Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

We will programmatically validate these. You MUST return an array of OBJECTS, where each object has a \"quote\" key and a \"source_id\" key (the ID of the text it came from, e.g., the ID). Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival. The results confirm that fermented beet waste can be transformed into multifunctional, sustainable health-promoting raw materials."

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders."

Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations."

Targeting the gut-kidney axis with probiotics is a promising strategy, but most candidates are food-derived and not human-adapted. We isolated two Lactiplantibacillus strains, Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02, from the healthy newborn skin representing a relatively unperturbed, early-life human microbiome. In vitro, these two human-derived probiotic strains showed robust survival under simulated gastrointestinal conditions and efficiently degraded UA precursors (inosine, guanosine). In Uox-/- mice, oral supplementation with these probiotics for 12\u00a0weeks significantly reduced serum UA levels, improved renal function, and regulated key urate transporters, such as ABCG2, GLUT9, and OAT1, in kidney and ileum. The treatment also reinforced intestinal barrier integrity by upregulating tight junction proteins (Claudin-1, Occludin, ZO-1) and alleviated renal fibrosis by inhibiting the TGF-\u03b21/SMAD3 signaling pathway. Gut microbiome analysis showed that JWN01 and JWN02 administration reshaped the microbial composition by decreasing potentially harmful genera (Mammaliicoccus, Staphylococcus, Corynebacterium) and enriching beneficial taxa (Muribaculaceae, Lactiplantibacillus, Akkermansia). This microbial shift was accompanied by partial restoration of disturbed gut metabolites, including Coenzyme Q10 and p-cresol sulfate. Proteomic profiling of proximal tubules, along with subsequent validation, demonstrated that intervention with JWN01 and JWN02 suppressed pathological autophagy-evidenced by reduced ULK1, LC3A/B, and Beclin-1 expression, and increased P62 levels. Notably, the potential inflammation-related biomarkers MSP and IBA1, elevated in HN, were reversed following probiotic treatment. Together, these findings indicate that L. pentosus JWN01 and L. plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia."

To begin to address this gap in knowledge, we developed an online survey to assess participant familiarity with different types of fermented products, determine consumption frequency, and gain insight into the motivation for consumption. A total of 751 participants completed the survey. Yogurt was the most frequently identified fermented food (n\u202f=\u202f658; 87.62% of respondents). Participants reported consuming fermented cereal grains (n\u202f=\u202f307; 46.17%), fruits and vegetables (n\u202f=\u202f281; 42.26%), dairy products (n\u202f=\u202f204; 39.70%), soy/rice products (n\u202f=\u202f250; 37.60%) and fermented meats (n\u202f=\u202f204; 30.68%). Reported daily consumption was highest for categories of fermented cereal and dairy products, compared to the other categories which typically were consumed on a weekly or monthly basis. The primary motivator for consumption was taste (n\u202f=\u202f337; 50.68%) compared to health benefits (n\u202f=\u202f235; 35.34%) and cultural reasons (n\u202f=\u202f80; 12.03%).

Participants associated health benefits with all fermented products listed in the survey. Therefore, consumers may assume that all fermented foods confer the same health benefits. The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved."

Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment."

However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity."

A traditional Chinese medicine formula, known as the Qihuang Biwen decoction (QHBW), has been shown to have immunomodulatory benefits in clinical and experimental studies. Nevertheless, few studies have investigated the effects of microbial-fermented QHBW (FQHBW) on immunity. In this study, we used one-way and Plackett-Burman analyses to establish the preparation process of FQHBW (crucial parameters: ratio of bacterial strains LZU-J-TSL6 and LZU-S-ZCJ was 3:1, inoculum quantity was 3%, temperature was 37\u2103, time was 37\u00a0h). The study found that FQHBW has increased total polysaccharide, total acid, and antioxidant capacities. The increased constituents after fermentation potentially contribute to improving the ability of FQHBW to regulate immunity. Next, its immunostimulatory activity was evaluated in cyclophosphamide (CTX)-treated mice, and the possible mechanism was studied by microbiome-metabolome analysis. As expected, FQHBW effectively ameliorated CTX-induced immunosuppression by improving organ index, lymphocyte proliferation, phagocytic function, cytokine secretion, and antioxidant profile. It protected against CTX-induced intestinal dysbiosis by promoting the abundance of Oscillospira, Allobaculum, and Coprococcus, while moderately increasing Akkermansia and reducing Staphylococcus and Streptococcus. FQHBW primarily influenced amino acid and nucleotide metabolism to benefit immunity. Unlike QHBW, FQHBW uniquely up-regulates dopamine synapses, tryptophan metabolism, and nicotinate and nicotinamide metabolism, promoting host anti-oxidation, immune system remodeling, and disease resistance. This study suggests that microbial fermentation is indeed an effective strategy to alter the properties and function of QHBW. FQHBW has the potential to replace QHBW as a novel immunoenhancer and intestinal microecological regulator."

In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

Endogenous purine biosynthesis and purinosome formation are neglected in research of medical mechanism. In this study, the therapeutic effect and mechanism of metformin was explored in chronic high-fructose-induced hyperuricemic rats. Results indicated that four weeks of metformin administration effectively reduced uric acid (UA), creatinine, and urea levels, ameliorated renal and hepatic injuries, and promoted glycogen synthesis in hyperuricemic rats. Furthermore, metformin remarkedly downregulated the mRNA and protein expression of core enzymes in pentose phosphate pathway (PPP), and de novo purine biosynthesis (DNPB) of endogenous purine. Metformin was found to markedly inhibit the purine salvage pathway (PSP) and XOD to retard purine recycling and metabolism. Additionally, metformin effectively restored physiological purinosome architecture, preventing aberrant enzyme clustering and subcellular redistribution. The hepatic levels of IMP, inosine, hypoxanthine and xanthine in hyperuricemic rats were remarkably decreased by metformin. Besides, metformin favorably maintained the gut microbiome homeostasis and normalized purine metabolism to lower purine levels in intestine. Taken together, the results for the first time indicated that metformin exerted appreciable anti-hyperuricemic effect, at least partly, via inhibiting original biosynthetic and metabolic pathways of endogenous purine simultaneously mediated by PPP/DNPB/XOD, purinosome assembly, and modulating gut microflora profile. This work provided a scientific basis for its potential application in hyperuricemia therapy beyond its classical use in diabetes."

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

However, the mechanisms through which 3'-SL alleviates antibiotic-associated diarrhea remain poorly understood. In this study, an antibiotic-associated diarrhea model was established through the co-administration of ampicillin and neomycin.

Furthermore, 3'-SL reduced serum levels of IL-6, tumor necrosis factor (TNF)-\u03b1, and IL-1\u03b2, while increasing IL-10 levels in the mice. Moreover, 3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice. 16S rRNA analysis revealed that mice in the 3'-SL group exhibited greater abundances of Akkermansia, Bacteroides, and Dubosiella, along with a reduced relative abundance of the diarrhea-associated bacterium Alloprevotella. Furthermore, metabolomics analysis indicated that 3'-SL promoted enrichment of purine metabolism, pyrimidine metabolism, nucleotide metabolism, and the pentose phosphate pathway, which may be associated with diarrhea development, inflammation amelioration, and barrier regulation. In conclusion, our findings suggest that 3'-SL ameliorates antibiotic-associated diarrhea by modulating gut microbiota and metabolite profiles."

Multiple studies have shown that Akkermansia muciniphila, as a promising beneficial gut bacterium, is robustly associated with positive effects on host metabolism, immunological regulation, and its presence inversely correlates with body weight. But the precise function played by this bacterium underlying lipid degradation is still unknown. Here we identify a metallophosphoesterase from A. muciniphila. The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies."

Astragalus membranaceus shows promise for DN, and microbial fermentation enhances herbal bioavailability and efficacy. This study compared fermented A. membranaceus broth (FA) and its aqueous extract (EA) in streptozotocin-induced DN rats, with 8-week low/medium/high-dose treatment. FA outperformed EA in improving metabolic parameters and renal function: superior body weight recovery, greater reductions in fasting blood glucose, serum BUN, ALT, and TG, enhanced renal antioxidant capacity (elevated SOD/GSH-Px and reduced MDA), and alleviated glomerular/tubular injury and interstitial inflammation. Chemical profiling identified 14 FA bioactive components; network pharmacology revealed core targets (STAT3, IL6, and TGFB1) and key pathways (AGE-RAGE, HIF-1, and FoxO). Fermentation boosts A. membranaceus efficacy in DN via better active constituent bioavailability, conferring stronger antioxidant, metabolic, and renoprotective effects, making FA a promising therapeutic and bioprocessing a strategy to upgrade traditional herbs."

Targeted therapies, including immune checkpoint inhibitors (ICIs), phosphatidylinositol 3-kinase (PI3K) inhibitors and EGFR-tyrosine kinase inhibitors (TKIs), are both influenced by and themselves influence the patients' nutritional and metabolic status. Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount. Rational individualized approaches based on detailed and dynamic clinical assessment of patient-, cancer- and treatment-related factors, using validated prognostic scores and biomarkers, are needed to maximize the potential of precision nutrition now and in future trials in this arena."

Probiotics, which modulate the gut microbiome, hold considerable promise for both prophylaxis and therapeutic intervention. This requires deeper insights into the kinetic changes and molecular mechanisms upon probiotic entry into the body. In this study, we utilized advanced molecular imaging to delineate the in vivo kinetic dynamics of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations: a liquid culture and a lyophilized powder. Our results provide new insights into the gastrointestinal transit and growth kinetics of the different probiotics formulations. Strikingly, the liquid LPZ achieved its peak growth phase within a relatively short period of 6 to 8 h post-ingestion, culminating in a 270- to 680-fold increase in residues at the 24th hour post-ingestion when compared to the lyophilized powder LPZ. Furthermore, during peak in vivo replication, LPZ enhanced gut microbial diversity and enriched beneficial commensal communities. Functionally, LPZ ingestion attenuated virulence factors while upregulating carbohydrate-active enzymes. Notably, LPZ significantly reduced xanthine levels, a metabolite associated with hyperuricemia, thereby providing a mechanistic basis for the observed relief from gout symptoms. This supports the mechanism of prior clinical findings and paves the way for future clinical trials and therapeutic use of LPZ and related probiotics. The innovation of this study lies in visualizing the kinetic changes of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations (a liquid culture and lyophilized powder) within the gastrointestinal tract. It was found that liquid LPZ proliferates in vivo with a higher retention rate. Furthermore, we also found that when liquid LPZ reaches its peak proliferation phase in vivo, it not only effectively promotes the proliferation of other beneficial bacteria and the production of their metabolites but also generates more carbohydrate-active enzymes while reducing virulence factors, thereby amplifying the functions of LPZ. Meanwhile, we observed that liquid LPZ significantly reduces the production of xanthine in vivo, indicating its potential to lower uric acid. In light of the aforementioned findings, we herein propose the concept of \"probiotikinetics.\" These results provide new insights into the intake of LPZ, along with important evidence for its application in healthy populations."

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment."

To begin to address this gap in knowledge, we developed an online survey to assess participant familiarity with different types of fermented products, determine consumption frequency, and gain insight into the motivation for consumption. A total of 751 participants completed the survey. Yogurt was the most frequently identified fermented food (n\u202f=\u202f658; 87.62% of respondents). Participants reported consuming fermented cereal grains (n\u202f=\u202f307; 46.17%), fruits and vegetables (n\u202f=\u202f281; 42.26%), dairy products (n\u202f=\u202f204; 39.70%), soy/rice products (n\u202f=\u202f250; 37.60%) and fermented meats (n\u202f=\u202f204; 30.68%). Reported daily consumption was highest for categories of fermented cereal and dairy products, compared to the other categories which typically were consumed on a weekly or monthly basis. The primary motivator for consumption was taste (n\u202f=\u202f337; 50.68%) compared to health benefits (n\u202f=\u202f235; 35.34%) and cultural reasons (n\u202f=\u202f80; 12.03%).

Participants associated health benefits with all fermented products listed in the survey. Therefore, consumers may assume that all fermented foods confer the same health benefits. The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved."

However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity."

In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies."

Targeted therapies, including immune checkpoint inhibitors (ICIs), phosphatidylinositol 3-kinase (PI3K) inhibitors and EGFR-tyrosine kinase inhibitors (TKIs), are both influenced by and themselves influence the patients' nutritional and metabolic status. Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount. Rational individualized approaches based on detailed and dynamic clinical assessment of patient-, cancer- and treatment-related factors, using validated prognostic scores and biomarkers, are needed to maximize the potential of precision nutrition now and in future trials in this arena."

In this study, 50 LAB strains previously isolated from Korean traditional fermented foods and obtained from the National Agrobiodiversity Center (KACC, Jeonju-si, Republic of Korea) were systematically screened for bifunctional carbohydrate and protein degradation capacities, and their potential to improve the nutritional functionality of wheat bran was evaluated. Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations."

The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival.

Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD."

However, their broader use in food formulations is often limited by the presence of anti-nutritional factors (ANF) and other compounds that may negatively affect digestibility, technological performance, and sensory acceptability. In recent years, different technological and biotechnological strategies have been explored to enhance the nutritional and functional properties of legumes and legume-derived ingredients. Among these approaches, fermentation has emerged as a particularly effective and sustainable process widely applied in several traditional food systems. The use of selected lactic acid bacteria and fermentation processes inspired by sourdough technology has demonstrated a strong ability to reduce ANF, improve protein digestibility and nutrient bioavailability, and enhance the technological and sensory characteristics of legume flours and grains. In addition, fermentation contributes to improving food safety through the inhibition or transformation of spoilage microorganisms, pathogens, and toxic compounds. Beyond their direct consumption, fermented legumes are also key components of many traditional foods and can be successfully incorporated into innovative formulations of staple products, including baked goods and pasta, leading to foods with improved nutritional, functional, and shelf-life properties."

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders."

This study investigated the synergistic effects and underlying mechanisms of polystyrene NPs and ABM at environmentally relevant concentrations in juvenile rainbow trout (Oncorhynchus mykiss) during a 28-day exposure. Compared to ABM alone, co-exposure with NPs induced significantly greater synergistic toxicity. This was evidenced by exacerbated intestinal barrier dysfunction, including downregulation of tight junction proteins (Occludin, Claudin-23, ZO-1) and a shift in the gut microbiota characterized by the enrichment of potential pathogens, such as Neochlamydia. In the liver, the combined exposure markedly enhanced oxidative stress and inflammatory responses. Untargeted metabolomics further revealed that the co-exposure disturbed fundamental metabolic pathways more profoundly than either contaminant alone, particularly affecting amino acid, carbohydrate, and nucleotide metabolism. Critically, correlation analyses integrated gut microbiota dysbiosis with hepatic metabolic disorders, supporting a pivotal role for gut-liver axis disruption in the synergistic toxicity. Our findings demonstrate that NPs can act as an aggravating factor, significantly potentiating the physiological and toxicological impacts of ABM on fish via interconnected intestinal and hepatic pathways.

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment."

The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved."

However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity."

In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

However, the mechanisms through which 3'-SL alleviates antibiotic-associated diarrhea remain poorly understood. In this study, an antibiotic-associated diarrhea model was established through the co-administration of ampicillin and neomycin. The effects of 3'-SL supplementation on diarrhea phenotype, inflammation, intestinal permeability, and barrier function were examined in antibiotic-associated diarrhea-model mice. Moreover, gut microbiota composition, metabolite profiles, and their alterations were analyzed using genomic and metabolomic approaches. The results demonstrate that 3'-SL increased body weight and aquaporin (AQP) 3 and AQP4 levels but reduced diarrhea rate, cecal mass, and fecal water content in the model mice, indicating its therapeutic effect on diarrhea. Furthermore, 3'-SL reduced serum levels of IL-6, tumor necrosis factor (TNF)-\u03b1, and IL-1\u03b2, while increasing IL-10 levels in the mice. Moreover, 3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice. 16S rRNA analysis revealed that mice in the 3'-SL group exhibited greater abundances of Akkermansia, Bacteroides, and Dubosiella, along with a reduced relative abundance of the diarrhea-associated bacterium Alloprevotella. Furthermore, metabolomics analysis indicated that 3'-SL promoted enrichment of purine metabolism, pyrimidine metabolism, nucleotide metabolism, and the pentose phosphate pathway, which may be associated with diarrhea development, inflammation amelioration, and barrier regulation. In conclusion, our findings suggest that 3'-SL ameliorates antibiotic-associated diarrhea by modulating gut microbiota and metabolite profiles."

Multiple studies have shown that Akkermansia muciniphila, as a promising beneficial gut bacterium, is robustly associated with positive effects on host metabolism, immunological regulation, and its presence inversely correlates with body weight. But the precise function played by this bacterium underlying lipid degradation is still unknown. Here we identify a metallophosphoesterase from A. muciniphila. The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies."

Targeted therapies, including immune checkpoint inhibitors (ICIs), phosphatidylinositol 3-kinase (PI3K) inhibitors and EGFR-tyrosine kinase inhibitors (TKIs), are both influenced by and themselves influence the patients' nutritional and metabolic status. Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount. Rational individualized approaches based on detailed and dynamic clinical assessment of patient-, cancer- and treatment-related factors, using validated prognostic scores and biomarkers, are needed to maximize the potential of precision nutrition now and in future trials in this arena."

In this study, 50 LAB strains previously isolated from Korean traditional fermented foods and obtained from the National Agrobiodiversity Center (KACC, Jeonju-si, Republic of Korea) were systematically screened for bifunctional carbohydrate and protein degradation capacities, and their potential to improve the nutritional functionality of wheat bran was evaluated. Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations."

The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival.

Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD."

In addition, fermentation contributes to improving food safety through the inhibition or transformation of spoilage microorganisms, pathogens, and toxic compounds. Beyond their direct consumption, fermented legumes are also key components of many traditional foods and can be successfully incorporated into innovative formulations of staple products, including baked goods and pasta, leading to foods with improved nutritional, functional, and shelf-life properties."

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders."

This study investigated the synergistic effects and underlying mechanisms of polystyrene NPs and ABM at environmentally relevant concentrations in juvenile rainbow trout (Oncorhynchus mykiss) during a 28-day exposure. Compared to ABM alone, co-exposure with NPs induced significantly greater synergistic toxicity. This was evidenced by exacerbated intestinal barrier dysfunction, including downregulation of tight junction proteins (Occludin, Claudin-23, ZO-1) and a shift in the gut microbiota characterized by the enrichment of potential pathogens, such as Neochlamydia. In the liver, the combined exposure markedly enhanced oxidative stress and inflammatory responses. Untargeted metabolomics further revealed that the co-exposure disturbed fundamental metabolic pathways more profoundly than either contaminant alone, particularly affecting amino acid, carbohydrate, and nucleotide metabolism. Critically, correlation analyses integrated gut microbiota dysbiosis with hepatic metabolic disorders, supporting a pivotal role for gut-liver axis disruption in the synergistic toxicity. Our findings demonstrate that NPs can act as an aggravating factor, significantly potentiating the physiological and toxicological impacts of ABM on fish via interconnected intestinal and hepatic pathways.

Natural polysaccharides-high-molecular-weight carbohydrate polymers derived from plants, fungi, marine organisms, and animal sources-have emerged as a promising class of multi-target bioactive agents for T2DM management. This comprehensive review first outlines the key pathophysiological mechanisms of T2DM, encompassing insulin resistance, pancreatic \u03b2-cell dysfunction, chronic inflammation, oxidative stress, and gut microbiota dysbiosis. We then systematically review the natural sources and structural classification of polysaccharides, alongside their extraction and purification methods. The core of this review examines the molecular mechanisms by which natural polysaccharides ameliorate T2DM: (1) enhancing insulin sensitivity and glucose metabolism via the PI3K/Akt and AMPK signaling pathways; (2) protecting pancreatic \u03b2-cells from apoptosis and promoting insulin secretion; (3) suppressing chronic inflammation through NF-\u03baB and NLRP3 pathway inhibition; (4) attenuating oxidative stress via Nrf2/HO-1 pathway activation; and (5) restoring gut microbiota homeostasis, reinforcing intestinal barrier integrity, and elevating short-chain fatty acids production. Structure-activity relationship analyses indicate that hypoglycemic efficacy is tightly correlated with molecular weight, monosaccharide composition, glycosidic linkage types, degree of branching, three-dimensional conformation, and chemical derivatization. Finally, challenges surrounding clinical translation, standardization, and bioavailability are discussed, along with future research directions. This review provides a theoretical framework for the application of natural polysaccharides as functional foods, nutraceuticals, or lead compounds in T2DM prevention and treatment."

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources."

Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD."

Short-chain fatty acids (SCFAs) serve as central immunomodulatory metabolites mediate the crosstalk between the gut and lung. Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis. Meanwhile, to evaluate the therapeutic potential of TCM in treating ALI by modulating the gut microbiota and enhancing SCFA production.

Keywords included \"short-chain fatty acid\", \"gut microbes\", \"acute lung injury\", \"traditional Chinese medicine\", and related terms. The search focused on preclinical and mechanistic studies investigating SCFA signaling, gut microbiota remodeling, and the therapeutic effects of herbal compounds or their active constituents in ALI/ARDS models.

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767."

Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations.

Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions."

However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment."

Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions. In an intervention setting, butyrate supplementation partially ameliorated inflammatory and barrier-related readouts and improved behavioral performance."

This study investigated the mechanisms by which Bifidobacterium animalis subsp. lactis Probio-M8 fermented milk enhances digestive efficiency and protects against dextran sulfate sodium-induced colitis in rats. FM8 supplementation promoted weight gain without excessive adipogenesis, elevated leptin levels, and amplified sucrase, lactase, aminopeptidase, and lipase activities, outperforming conventional fermented milk.

In dextran sulfate sodium-challenged rats, FM8 pre-administration attenuated colitis severity by reducing disease activity index scores, normalizing colon histology, and suppressing interleukin (IL)-6 and IL-17 while elevating IL-10 and IL-22. Mechanistically, FM8 enriched Bifidobacterium animalis and butyrate levels, which inversely correlated with mucosal injury and pro-inflammatory cytokines.

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy."

While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels."

VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis."

However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936.

The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1.

Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources."

Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis.

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767."

This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis. By integrating epithelial protection, immunomodulation, and microbial reshaping, it represents a promising dietary strategy for the management of Inflammatory Bowel Diseases."

As functional proxies of their parent bacteria, probiotic extracellular vesicles (PEVs) have become the focus of attention in recent years because of their great potential in the treatment of IBD. This review summarizes the overview of PEVs and recent advances of PEVs on the therapeutical effect and potential mechanisms in IBD. In addition, the review discusses the possible applications and challenges of PEVs in IBD. Key scientific concepts of review: PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Although PEVs offer powerful innovations for the treatment of IBD, they still face challenges such as high-quality and scaled-up production, purification, safety, target specificity, and bioavailability. Consequently, future investigations will focus on establishing standard procedures of isolation, purification, and quality control while engineering PEVs for enhanced target-specific delivery in IBD treatment."

Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions."

However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment."

Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions. In an intervention setting, butyrate supplementation partially ameliorated inflammatory and barrier-related readouts and improved behavioral performance."

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy."

While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels."

VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis."

However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936. To improve its intestinal colonization efficiency, we constructed double-layered multinucleated microcapsules (probiotic microcapsules) of B. adolescentis FS2-3 and evaluated their effects on bacterial enteritis induced by five representative foodborne pathogens. The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1. These findings provide new insights into the application of probiotic microcapsules in the treatment of enteritis."

Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources."

Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures.

Short-chain fatty acids (SCFAs) serve as central immunomodulatory metabolites mediate the crosstalk between the gut and lung. Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis. Meanwhile, to evaluate the therapeutic potential of TCM in treating ALI by modulating the gut microbiota and enhancing SCFA production. A comprehensive literature search was conducted across PubMed, Ovid-Embase, Web of Science, and CNKI databases (2010-2025). Keywords included \"short-chain fatty acid\", \"gut microbes\", \"acute lung injury\", \"traditional Chinese medicine\", and related terms. The search focused on preclinical and mechanistic studies investigating SCFA signaling, gut microbiota remodeling, and the therapeutic effects of herbal compounds or their active constituents in ALI/ARDS models. This review identified acetate, propionate, and butyrate as key mediators that protect against ALI through distinct mechanisms, including anti-oxidation, anti-inflammation, immunomodulation, apoptosis reduction, airway tight-junction protection, and regulation of intestinal homeostasis.

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767."

This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis. By integrating epithelial protection, immunomodulation, and microbial reshaping, it represents a promising dietary strategy for the management of Inflammatory Bowel Diseases."

Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions."

However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment."

Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions. In an intervention setting, butyrate supplementation partially ameliorated inflammatory and barrier-related readouts and improved behavioral performance."

This study investigated the mechanisms by which Bifidobacterium animalis subsp. lactis Probio-M8 fermented milk enhances digestive efficiency and protects against dextran sulfate sodium-induced colitis in rats. FM8 supplementation promoted weight gain without excessive adipogenesis, elevated leptin levels, and amplified sucrase, lactase, aminopeptidase, and lipase activities, outperforming conventional fermented milk. Metagenomic analysis revealed microbial restructuring with Corynebacterium glutamicum and Bifidobacterium animalis enrichment, and increased short-chain fatty acids.Untargeted metabolomics identified FM8-responsive metabolites, including p-hydroxybenzaldehyde and indole-3-carboxaldehyde, linked to anti-inflammatory pathways. In dextran sulfate sodium-challenged rats, FM8 pre-administration attenuated colitis severity by reducing disease activity index scores, normalizing colon histology, and suppressing interleukin (IL)-6 and IL-17 while elevating IL-10 and IL-22. Mechanistically, FM8 enriched Bifidobacterium animalis and butyrate levels, which inversely correlated with mucosal injury and pro-inflammatory cytokines. These findings demonstrate that FM8 enhances gastrointestinal health through tripartite microbiota-metabolite-immune interactions, highlighting its functional potential for metabolic optimization and colitis prevention."

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy."

While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels."

VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis."

However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936. To improve its intestinal colonization efficiency, we constructed double-layered multinucleated microcapsules (probiotic microcapsules) of B. adolescentis FS2-3 and evaluated their effects on bacterial enteritis induced by five representative foodborne pathogens. The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1.

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

However, the therapeutic application of live A. muciniphila in IBD remains controversial. Interestingly, A. muciniphila-derived extracellular vesicles (AEVs) have been reported to improve intestinal barrier function, immune status, and gut microbiota composition, and may exert superior efficacy in IBD. In parallel, pasteurized A. muciniphila has been shown to retain, or even enhance, beneficial bioactivity compared with the live bacterium in certain disease settings. Here, we investigated whether extracellular vesicles derived from pasteurized A. muciniphila (PAEVs) preserve or further enhance the anti-inflammatory and barrier-protective effects of the parental bacterium. A dextran sulfate sodium (DSS)-induced mouse model of colitis was used to evaluate the therapeutic effects of PAEVs and AEVs. Disease severity, body weight loss, colonic histopathology, inflammatory cytokine expression, intestinal barrier integrity, inflammatory signaling pathways, and gut microbiota composition were assessed. PAEVs markedly attenuated DSS-induced colitis, as evidenced by reduced weight loss, improved colonic histology, decreased levels of TNF-\u03b1, IL-6, and IFN-\u03b3, and enhanced tight junction proteins. By contrast, AEVs improved only limited parameters, including Occludin expression and TNF-\u03b1 levels. Mechanistically, PAEV-mediated protection may be associated with suppression of the STING/I\u03baB/NF-\u03baB signaling axis and remodeling of the gut microbiota. These findings indicate that PAEVs effectively alleviate experimental IBD by enhancing tight junction proteins, suppressing some inflammatory cytokines, and modulating gut microbiota composition. Compared with AEVs, PAEVs exhibit broader protective effects, suggesting that extracellular vesicles derived from pasteurized A. muciniphila may represent a promising postbiotic strategy for IBD intervention. Importantly, this study offers the first systematic comparison of extracellular vesicles derived from live and pasteurized A. muciniphila, highlighting PAEVs as a distinct and potentially more effective postbiotic vesicle formulation for IBD intervention."

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition.

Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health."

However, low bioavailability and unclarified therapeutic mechanisms impeded its deeply application. Plant-derived exosome-like nanoparticles offered a promising option for improving bioavailability and targeted delivery capability. To obtain dark tea-derived exosome-like nanovesicles (DTELNs) and clarify their material basis, investigate the therapeutic effects on hepatocyte carcinoma (HCC) and potential mechanisms. DTELNs were isolated by tangential flow filtration, TEM, NTA, nucleic acid & protein analysis system and LC-MS/MS were used to characterize their morphological characteristics and chemical composition. Orthotopic HCC model mice were established and employed for DTELNs' oral administration. Living imaging, H&E staining and biochemical assays were used to evaluate therapeutic effects. Untargeted metabolomic, 16S rRNA sequencing and cytometry by time-of-flight (CyTOF) were used to investigate the alteration of endogenous substances and immune features. Potential targets were explored by network pharmacology, protein-protein interaction, and verified by western blot. Finally, HCC patient-derived organoids were generated to evaluate the clinical applicability of DTELNs. DTELNs exhibited typical exosomal features, major components including flavonoids, phenolic acids, lipids, amino acids and their derivatives, and miRNAs. DTELNs markedly suppressed tumor proliferation, modulated gut microbial diversity, normalized liver-gut axis physiological homeostasis and enhanced immune responses. DTELNs distinctly downregulated the expressions of p-Akt, NF-\u03baB, Bcl-2, cyclin D1, upregulated the expressions of p-p53, PTEN, Bax, cleaved-caspase 3 and p21. DTELNs also exhibited potent inhibitory effect on HCC organoids. DTELNs demonstrated potent therapeutic efficacy against HCC. The mechanisms mainly involved directly modulating Akt-related signalling pathways, rebalancing gut microbiota and related metabolites, and further boosting anti-tumor immune responses."

These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Co-formulation with Brassica rapa L. polysaccharide offers a promising strategy to enhance its functionality; however, the impact of different colloidal delivery systems on the encapsulation performance and subsequent biological fate of this mixture remains unclear. In this study, we systematically compared three spray-dried delivery platforms, including liposomes (LP-CP), sodium caseinate nanoparticles (SC-CP), and \u03b2-cyclodextrin inclusion complexes (CYC-CP), for encapsulating CP. Our results demonstrated that the carrier system critically determined encapsulation performance, with SC-CP exhibiting superior curcumin loading capacity (7.24%), curcumin thermal stability (82.87% retention at 95\u00a0\u00b0C), and favorable hygroscopicity profiles. Notably, SC-CP facilitated enhanced colonic accumulation in vivo, achieving a peak accumulation of 53.45% at 8\u00a0h post-gavage, representing a 15-fold increase compared to curcumin from unencapsulated CP. By integrating in vitro fermentation models with in vivo animal experiments and employing 16S rRNA sequencing alongside short-chain fatty acid (SCFA) analysis, we systematically elucidated the carrier-specific modulatory effects on the gut microbiota. In the in vitro fermentation system, SC-CP significantly promoted the production of acetate, propionate, and butyrate, while enriching butyrate-producing genera such as Lachnospiraceae_NK4A136_group. In the in vivo animal model, SC-CP intervention resulted in a 1.6-fold increase in cecal butyrate levels and a marked increase in the abundance of beneficial genera, including Akkermansia, demonstrating superior modulation of microbial community structure and metabolic function. Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology. This study provides a theoretical foundation for the rational selection of delivery systems to maximize the functional efficacy of bioactive ingredients in functional food applications."

Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems."

Resistant to upper gastrointestinal digestion, they reach the colon where gut microbiota ferment them into metabolites, chiefly short-chain fatty acids (SCFAs). These metabolites in turn modulate intestinal barrier integrity, immune and metabolic homeostasis, and inter-organ signaling. However, a critical caveat is that each polysaccharide type exhibits substantial structural variability in molecular weight, degree and position of sulfation, monosaccharide composition, and linkage pattern, depending on species, harvest time, and extraction method. This variability fundamentally alters fermentation kinetics and SCFA profiles, yet most studies treat these polysaccharides as uniform entities. This review critically synthesizes current in vitro and in vivo evidence and emphasizes that the therapeutic significance of seaweed polysaccharides lies in their microbiota-mediated, multi-organ actions rather than in isolated biological effects. In addition, we analyzed the main challenges for food and health applications, including variability in polysaccharide sources and extraction methods, limited bioavailability, pollution risk, and the lack of coordinated global regulations. Addressing these gaps is essential for translating promising biological activities into safe, standardized functional components and for developing these polysaccharides into functional ingredients that can modulate the gut-liver-brain axis."

The gut-kidney axis has emerged as a key factor in cisplatin-induced AKI, with gut microbial imbalance contributing to inflammation and metabolic dysregulation. Astragalus polysaccharides (APS), the main bioactive constituents of Astragalus membranaceus, have shown potential in mitigating AKI, partly through modulation of the gut microbiota. Clinical sequencing data indicate that cisplatin treatment reduces short-chain fatty acid (SCFA)-producing bacteria (e.g., Faecalibacterium, Roseburia) and increases potentially pathogenic groups (e.g., Enterobacteriaceae), leading to alterations in SCFA, amino acid, and bile acid metabolism. This study integrates these findings with existing literature to propose a molecular-weight (Mw)-defined APS model targeting the gut-kidney axis. While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects. Advanced gut-targeted delivery systems are also discussed as strategies to enhance APS bioavailability and colonic targeting. Understanding these Mw-dependent mechanisms is critical for developing APS as a precise adjunct therapy to prevent cisplatin-induced AKI and improve patient outcomes."

Emerging evidence highlights the gut-lung axis as a potential therapeutic target, with probiotics proposed to modulate Th17-related inflammatory pathways. In this randomized, double-blind, placebo-controlled trial, 50 patients with mild-to-moderate COPD were enrolled; 44 completed the 8-week intervention (23 probiotics, 21 placebo). Participants received either a multistrain probiotic formulation or placebo. Outcomes included spirometry, COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and serum IL-6, IL-17, and TGF-\u03b2 levels. Probiotic supplementation significantly improved FEV1 and FVC within the intervention group, although between-group spirometric differences were not significant. IL-6 levels declined significantly following probiotic therapy, with a significantly greater reduction compared to placebo, whereas IL-17 and TGF-\u03b2 remained unchanged. CAT scores improved significantly in the probiotic group, exceeding the minimal clinically important difference and demonstrating a significant between-group effect. No significant change was observed in mMRC scores. Eight weeks of probiotic supplementation was associated with reduced systemic IL-6 levels and clinically meaningful improvement in patient-reported outcomes in mild-to-moderate COPD. These findings support a potential adjunctive role for probiotics and warrant larger mechanistic trials.

Its high morbidity and mortality have posed a substantial public health burden, with current symptomatic treatments exhibiting inadequate control and potential adverse effects. With advances in microecological research techniques, the critical role of microbial homeostasis in the oral cavity, lungs, and gut in respiratory health has become increasingly prominent, and microbial dysbiosis is closely associated with progression and therapeutic outcomes of COPD. This review summarizes the compositional alterations of oral, lung, and gut microbiota in COPD patients, analyzes the interactions of the oral-lung axis and gut-lung axis, and delineates three mechanisms through which microbial dysbiosis promotes COPD progression: pathogenic bacterial migration, abnormal metabolite production and immune dysregulation. Additionally, this review summarizes Western and traditional Chinese medicine interventions targeting microbiota homeostasis, including antibiotics, microecological preparations, and herbal medicines, which have shown potential in improving COPD clinical outcomes. This review aims to provide a theoretical reference for the clinical diagnosis and management of COPD. Millions of people worldwide live with chronic obstructive pulmonary disease (COPD), which brings persistent breathing struggles that disrupt their daily living. Current standard treatments mainly relieve symptoms, but have limited effects on controlling disease progression, and may cause unwanted side effects. Mounting research shows that microbes in the mouth, lungs and gut play a critical role in maintaining lung health, while their imbalance can drive COPD progression. This review focused on the link between microbial balance and COPD to find new intervention ideas. We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders. We also sorted out Western and traditional Chinese medicine strategies that restore microbial balance to improve COPD treatment and quality of life. These findings show a promising strategy for COPD therapy from the perspective of regulating microbial balance."

In its most serious manifestations, it can cause death by asphyxiation. Currently, no efficacious therapeutic interventions exist to avert or counteract these serious outcomes. Baicalein (BAI) is a core quality marker of the traditional Chinese medicine Scutellaria baicalensis, but the mechanism of its oral action remains unclear. Assess the therapeutic efficacy of BAI in AA mice models and investigate its mechanism of action. Evaluate the efficacy of BAI on ovalbumin-induced AA mice. To assess alterations in the pulmonary and gut microbial communities, 16S rRNA sequencing was employed. The integrity and restoration of the lung and intestinal epithelial lining were evaluated via immunohistochemistry. Furthermore, gas chromatography-mass spectrometry quantified fecal levels of short-chain fatty acids (SCFAs) in AA mice, and flow cytometry was used to analyze the content of ILC2 cells in colon tissue. Finally, the role of beneficial bacteria and their metabolites in inhibiting AA was further confirmed through fecal microbiota transplantation (FMT). Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins. Moreover, BAI mitigated colonic epithelial damage, inhibited ILC2s activation in the colon, enriched the abundance of gut probiotics capable of producing SCFAs, especially Akkermansia muciniphila (A. muciniphila), and increased the content of SCFAs such as propionic acid in feces. The FMT experiment conducted after gavage with broad-spectrum antibiotics confirmed that BAI mediated reversal of microbial dysbiosis plays a key role in the treatment of AA, significantly increasing the expression of GPR41 mRNA in colon tissue and inhibiting the activation of ILC2s. The potential prebiotic BAI mitigates AA via targeting A. muciniphila and its metabolites, which consequently inhibits epithelial damage and type 2 immune activation."

However, the dynamic interactions among pulmonary pathology, gut microbiota, and host metabolism during these episodes remains unclear. This study aimed to delineate the longitudinal characteristics of virus-induced AECOPD and identify potential biomarkers. Mice were exposed to cigarette smoke for eight weeks, followed by intranasal inoculation with IAV. A longitudinal assessment was conducted from day 1 to day 15 post-infection, integrating analyses of lung pathology, lung function, gut microbiome, and both serum and fecal metabolomes. Additionally, random forest modeling was employed to identify specific metabolic biomarkers associated with the acute exacerbation stage. Mice exposed to cigarette smoke and IAV exhibited significant pulmonary immune cell recruitment, impaired lung function, and emphysematous changes, peaking at day 5 post-infection. By day 15, acute airway inflammation had subsided; however, interstitial immune cell infiltration, collagen deposition, and emphysema persisted. 16S rRNA sequencing revealed dynamic shifts in gut microbiota composition, with the abundance of Intestinimonas positively correlating with pulmonary inflammatory markers. Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation. Random forest analysis identified 1-Methylnicotinamide (1-MNA) as a promising biomarker for distinguishing virus-triggered AECOPD, achieving an area under the curve (AUC) of 1.0. This study demonstrates that cigarette smoke combined with influenza infection induces persistent lung injury alongside concurrent disruption of intestinal flora and serum metabolism. The findings show that gut microbiota and metabolites are potential biomarkers and supplementation with unsaturated fatty acids may represent a novel therapeutic strategy for virus-induced AECOPD."

Although electroacupuncture (EA) demonstrates therapeutic potential in COPD, its mechanisms in modulating the gut-lung axis to alleviate inflammation and EMT remain unclear. In cigarette smoke and lipopolysaccharide (LPS)-induced COPD rats, we evaluated lung function, airway collagen deposition, pro-inflammatory and anti-inflammatory cytokines in serum, bronchoalveolar lavage fluid (BALF), and colon tissue, EMT markers in lung tissue, serum LPS levels, and 16S rRNA sequencing of lung and gut microbiota. Interventions comprised authentic EA at bilateral \"Feishu\" (BL13) and \"Zusanli\" (ST36) acupoints versus sham acupuncture at non-acupoint. Electroacupuncture significantly attenuated airway remodeling, as evidenced by improved lung function and reduced collagen deposition. EA modulated gut-lung microbiota by suppressing pro-inflammatory pathogens and enriching immunoregulatory taxa. These changes correlated with reduced serum endotoxemia and inflammation, marked by decreased pro-inflammatory cytokines and increased IL-10 in serum, BALF, and colon tissues. The ameliorated inflammatory environment was further linked to inhibition of EMT in airways, shown by upregulated epithelial markers and downregulated mesenchymal markers. Correlative analyses supported these associations. Ligilactobacillus enrichment negatively correlated with serum LPS, while Mycoplasmopsis positively associated with inflammation and EMT markers. Sham acupuncture failed to achieve these effects. Electroacupuncture ameliorates airway remodeling in COPD by modulating gut and lung microbiotareducing inflammation and inhibits EMT, suggesting microbiota regulation as a potential contributor to its therapeutic effects."

There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as milk may have fewer adverse effects associated with high-dose supplemental intake. Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation. Structural and functional manipulation of milk proteins, such as whey and lactoferrin, can also modify matrix functionality; for example, appropriate processing conditions can preserve lactoferrin's iron-binding capacity, supporting iron transport and bioavailability. Compared with plant-based milks, which often require fortification and extensive processing, the dairy milk matrix is particularly effective at promoting nutrient absorption. Our findings highlight the importance of adopting a whole food perspective when considering milk in dietary recommendations and research."

While intestinal microbiota, particularly Akkermansia muciniphila (AKK), has been linked to the regulation of ALI in adult murine model, its impact on juvenile hosts, who exhibit heightened susceptibility to lipopolysaccharide (LPS)-induced ALI, remains poorly understood. Moreover, despite microencapsulation enhancing the probiotic gastrointestinal survival and colonization of probiotics, the therapeutic potential of microencapsulated AKK (AKK-MC) in juvenile murine ALI has not been explored. In this study, juvenile mice were orally gavaged with live AKK or AKK-MC for 14 days, with LPS-induced ALI established on day 11. Lung tissues were analyzed for morphological changes and inflammatory cytokine analysis. Bronchoalveolar lavage fluid (BALF) was collected for total cell counts and protein concentration. Macrophages and neutrophils infiltration in the lungs was quantified via immunofluorescence staining. Four segments of the intestinal tract (jejunum, ileum, cecum, and colon) were harvested for histological analysis using hematoxylin and eosin (H&E), Alcian blue-periodic acid-Schiff (AB-PAS), and toluidine blue (TBO) staining. These evaluations included measurements of villus height to crypt depth, intestinal injury scoring, and counts of goblet and mast cells. AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage. This was evidenced by reduced protein concentration and cell counts in BALF, downregulation of Tnf-\u03b1 and Il-1\u03b2 expression, improved lung histology, and decreased macrophage infiltration and neutrophil extracellular traps formation. In the intestine, AKK treatment restored mucosal architecture, increased villus height to crypt depth ratios, maintained goblet cell populations, and reduced mast cell infiltration across intestinal segments. These results demonstrate that microencapsulation enhances AKK's efficacy in ameliorating LPS-induced ALI in juvenile mice through gut microbiota modulation. This study provides a crucial foundation for the development of probiotic-based interventions in pediatric ALI."

SARS-CoV-2 infection is known to disrupt the gut microbiome, but the downstream functional impacts on microbial metabolism and host immune responses remain insufficiently understood. Using K18-hACE2 transgenic mice, researchers investigated the effects of SARS-CoV-2 variants (WA and Omicron) on the gut microbiome and host immunity. Microbial composition and functional profiles were assessed post-infection. To test the therapeutic potential of Akkermansia muciniphila (A. muciniphila), live bacteria were administered prophylactically, and various outcomes were evaluated, including weight loss, lung pathology, immune cell phenotypes, and cytokine production. In K18-hACE2 transgenic mice infected with SARS-CoV-2, there was a marked reduction in gut microbial diversity, accompanied by a consistent enrichment of A. muciniphila. This microbial shift was associated with functional disruptions in key metabolic pathways, particularly those involved in glycosaminoglycan degradation and lipid metabolism, suggesting a broader impact of infection on microbial functionality. Remarkably, prophylactic administration of live A. muciniphila prior to infection led to significant protective effects. Treated mice exhibited reduced weight loss and improved lung histopathology compared to untreated controls. Local antiviral immune responses in the lung were notably enhanced without triggering excessive systemic inflammation. Mice receiving A. muciniphila also demonstrated elevated production of Th2 and Th17 cytokines, robust expansion of tissue-resident memory T cells, and the formation of inducible bronchus-associated lymphoid tissue (iBALT)-all indicative of potentiated mucosal immunity. These findings highlight a functional role for A. muciniphila not only as a microbial signature of COVID-19-associated dysbiosis but also as an active modulator of host immune responses during respiratory viral infections. These findings position A. muciniphila as both a biomarker of COVID-19-related gut dysbiosis and a potent live biotherapeutic candidate for respiratory infections. Its ability to enhance mucosal immune responses through gut-lung axis modulation highlights its promise in prophylactic strategies against viral respiratory diseases, including SARS-CoV-2."

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition. This chapter explores the mechanistic links between microbial metabolism and host health, reviews emerging fermentation technologies for targeted metabolite production, and highlights industrial case studies demonstrating the transition of precision fermentation from research to commercial applications."

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health."

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Co-formulation with Brassica rapa L. polysaccharide offers a promising strategy to enhance its functionality; however, the impact of different colloidal delivery systems on the encapsulation performance and subsequent biological fate of this mixture remains unclear. In this study, we systematically compared three spray-dried delivery platforms, including liposomes (LP-CP), sodium caseinate nanoparticles (SC-CP), and \u03b2-cyclodextrin inclusion complexes (CYC-CP), for encapsulating CP. Our results demonstrated that the carrier system critically determined encapsulation performance, with SC-CP exhibiting superior curcumin loading capacity (7.24%), curcumin thermal stability (82.87% retention at 95\u00a0\u00b0C), and favorable hygroscopicity profiles. Notably, SC-CP facilitated enhanced colonic accumulation in vivo, achieving a peak accumulation of 53.45% at 8\u00a0h post-gavage, representing a 15-fold increase compared to curcumin from unencapsulated CP. By integrating in vitro fermentation models with in vivo animal experiments and employing 16S rRNA sequencing alongside short-chain fatty acid (SCFA) analysis, we systematically elucidated the carrier-specific modulatory effects on the gut microbiota. In the in vitro fermentation system, SC-CP significantly promoted the production of acetate, propionate, and butyrate, while enriching butyrate-producing genera such as Lachnospiraceae_NK4A136_group. In the in vivo animal model, SC-CP intervention resulted in a 1.6-fold increase in cecal butyrate levels and a marked increase in the abundance of beneficial genera, including Akkermansia, demonstrating superior modulation of microbial community structure and metabolic function. Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology. This study provides a theoretical foundation for the rational selection of delivery systems to maximize the functional efficacy of bioactive ingredients in functional food applications."

Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems."

The gut-kidney axis has emerged as a key factor in cisplatin-induced AKI, with gut microbial imbalance contributing to inflammation and metabolic dysregulation. Astragalus polysaccharides (APS), the main bioactive constituents of Astragalus membranaceus, have shown potential in mitigating AKI, partly through modulation of the gut microbiota. Clinical sequencing data indicate that cisplatin treatment reduces short-chain fatty acid (SCFA)-producing bacteria (e.g., Faecalibacterium, Roseburia) and increases potentially pathogenic groups (e.g., Enterobacteriaceae), leading to alterations in SCFA, amino acid, and bile acid metabolism. This study integrates these findings with existing literature to propose a molecular-weight (Mw)-defined APS model targeting the gut-kidney axis. While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects. Advanced gut-targeted delivery systems are also discussed as strategies to enhance APS bioavailability and colonic targeting. Understanding these Mw-dependent mechanisms is critical for developing APS as a precise adjunct therapy to prevent cisplatin-induced AKI and improve patient outcomes."

Its high morbidity and mortality have posed a substantial public health burden, with current symptomatic treatments exhibiting inadequate control and potential adverse effects. With advances in microecological research techniques, the critical role of microbial homeostasis in the oral cavity, lungs, and gut in respiratory health has become increasingly prominent, and microbial dysbiosis is closely associated with progression and therapeutic outcomes of COPD. This review summarizes the compositional alterations of oral, lung, and gut microbiota in COPD patients, analyzes the interactions of the oral-lung axis and gut-lung axis, and delineates three mechanisms through which microbial dysbiosis promotes COPD progression: pathogenic bacterial migration, abnormal metabolite production and immune dysregulation. Additionally, this review summarizes Western and traditional Chinese medicine interventions targeting microbiota homeostasis, including antibiotics, microecological preparations, and herbal medicines, which have shown potential in improving COPD clinical outcomes. This review aims to provide a theoretical reference for the clinical diagnosis and management of COPD. Millions of people worldwide live with chronic obstructive pulmonary disease (COPD), which brings persistent breathing struggles that disrupt their daily living. Current standard treatments mainly relieve symptoms, but have limited effects on controlling disease progression, and may cause unwanted side effects. Mounting research shows that microbes in the mouth, lungs and gut play a critical role in maintaining lung health, while their imbalance can drive COPD progression. This review focused on the link between microbial balance and COPD to find new intervention ideas. We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders. We also sorted out Western and traditional Chinese medicine strategies that restore microbial balance to improve COPD treatment and quality of life.

In its most serious manifestations, it can cause death by asphyxiation. Currently, no efficacious therapeutic interventions exist to avert or counteract these serious outcomes. Baicalein (BAI) is a core quality marker of the traditional Chinese medicine Scutellaria baicalensis, but the mechanism of its oral action remains unclear. Assess the therapeutic efficacy of BAI in AA mice models and investigate its mechanism of action. Evaluate the efficacy of BAI on ovalbumin-induced AA mice. To assess alterations in the pulmonary and gut microbial communities, 16S rRNA sequencing was employed. The integrity and restoration of the lung and intestinal epithelial lining were evaluated via immunohistochemistry. Furthermore, gas chromatography-mass spectrometry quantified fecal levels of short-chain fatty acids (SCFAs) in AA mice, and flow cytometry was used to analyze the content of ILC2 cells in colon tissue. Finally, the role of beneficial bacteria and their metabolites in inhibiting AA was further confirmed through fecal microbiota transplantation (FMT). Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins. Moreover, BAI mitigated colonic epithelial damage, inhibited ILC2s activation in the colon, enriched the abundance of gut probiotics capable of producing SCFAs, especially Akkermansia muciniphila (A. muciniphila), and increased the content of SCFAs such as propionic acid in feces. The FMT experiment conducted after gavage with broad-spectrum antibiotics confirmed that BAI mediated reversal of microbial dysbiosis plays a key role in the treatment of AA, significantly increasing the expression of GPR41 mRNA in colon tissue and inhibiting the activation of ILC2s. The potential prebiotic BAI mitigates AA via targeting A. muciniphila and its metabolites, which consequently inhibits epithelial damage and type 2 immune activation."

However, the dynamic interactions among pulmonary pathology, gut microbiota, and host metabolism during these episodes remains unclear. This study aimed to delineate the longitudinal characteristics of virus-induced AECOPD and identify potential biomarkers. Mice were exposed to cigarette smoke for eight weeks, followed by intranasal inoculation with IAV. A longitudinal assessment was conducted from day 1 to day 15 post-infection, integrating analyses of lung pathology, lung function, gut microbiome, and both serum and fecal metabolomes. Additionally, random forest modeling was employed to identify specific metabolic biomarkers associated with the acute exacerbation stage. Mice exposed to cigarette smoke and IAV exhibited significant pulmonary immune cell recruitment, impaired lung function, and emphysematous changes, peaking at day 5 post-infection. By day 15, acute airway inflammation had subsided; however, interstitial immune cell infiltration, collagen deposition, and emphysema persisted. 16S rRNA sequencing revealed dynamic shifts in gut microbiota composition, with the abundance of Intestinimonas positively correlating with pulmonary inflammatory markers. Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation. Random forest analysis identified 1-Methylnicotinamide (1-MNA) as a promising biomarker for distinguishing virus-triggered AECOPD, achieving an area under the curve (AUC) of 1.0. This study demonstrates that cigarette smoke combined with influenza infection induces persistent lung injury alongside concurrent disruption of intestinal flora and serum metabolism. The findings show that gut microbiota and metabolites are potential biomarkers and supplementation with unsaturated fatty acids may represent a novel therapeutic strategy for virus-induced AECOPD."

Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as milk may have fewer adverse effects associated with high-dose supplemental intake. Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation. Structural and functional manipulation of milk proteins, such as whey and lactoferrin, can also modify matrix functionality; for example, appropriate processing conditions can preserve lactoferrin's iron-binding capacity, supporting iron transport and bioavailability. Compared with plant-based milks, which often require fortification and extensive processing, the dairy milk matrix is particularly effective at promoting nutrient absorption. Our findings highlight the importance of adopting a whole food perspective when considering milk in dietary recommendations and research."

While intestinal microbiota, particularly Akkermansia muciniphila (AKK), has been linked to the regulation of ALI in adult murine model, its impact on juvenile hosts, who exhibit heightened susceptibility to lipopolysaccharide (LPS)-induced ALI, remains poorly understood. Moreover, despite microencapsulation enhancing the probiotic gastrointestinal survival and colonization of probiotics, the therapeutic potential of microencapsulated AKK (AKK-MC) in juvenile murine ALI has not been explored. In this study, juvenile mice were orally gavaged with live AKK or AKK-MC for 14 days, with LPS-induced ALI established on day 11. Lung tissues were analyzed for morphological changes and inflammatory cytokine analysis. Bronchoalveolar lavage fluid (BALF) was collected for total cell counts and protein concentration. Macrophages and neutrophils infiltration in the lungs was quantified via immunofluorescence staining. Four segments of the intestinal tract (jejunum, ileum, cecum, and colon) were harvested for histological analysis using hematoxylin and eosin (H&E), Alcian blue-periodic acid-Schiff (AB-PAS), and toluidine blue (TBO) staining. These evaluations included measurements of villus height to crypt depth, intestinal injury scoring, and counts of goblet and mast cells. AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage. This was evidenced by reduced protein concentration and cell counts in BALF, downregulation of Tnf-\u03b1 and Il-1\u03b2 expression, improved lung histology, and decreased macrophage infiltration and neutrophil extracellular traps formation. In the intestine, AKK treatment restored mucosal architecture, increased villus height to crypt depth ratios, maintained goblet cell populations, and reduced mast cell infiltration across intestinal segments. These results demonstrate that microencapsulation enhances AKK's efficacy in ameliorating LPS-induced ALI in juvenile mice through gut microbiota modulation. This study provides a crucial foundation for the development of probiotic-based interventions in pediatric ALI."

SARS-CoV-2 infection is known to disrupt the gut microbiome, but the downstream functional impacts on microbial metabolism and host immune responses remain insufficiently understood. Using K18-hACE2 transgenic mice, researchers investigated the effects of SARS-CoV-2 variants (WA and Omicron) on the gut microbiome and host immunity. Microbial composition and functional profiles were assessed post-infection. To test the therapeutic potential of Akkermansia muciniphila (A. muciniphila), live bacteria were administered prophylactically, and various outcomes were evaluated, including weight loss, lung pathology, immune cell phenotypes, and cytokine production. In K18-hACE2 transgenic mice infected with SARS-CoV-2, there was a marked reduction in gut microbial diversity, accompanied by a consistent enrichment of A. muciniphila. This microbial shift was associated with functional disruptions in key metabolic pathways, particularly those involved in glycosaminoglycan degradation and lipid metabolism, suggesting a broader impact of infection on microbial functionality. Remarkably, prophylactic administration of live A. muciniphila prior to infection led to significant protective effects. Treated mice exhibited reduced weight loss and improved lung histopathology compared to untreated controls. Local antiviral immune responses in the lung were notably enhanced without triggering excessive systemic inflammation. Mice receiving A. muciniphila also demonstrated elevated production of Th2 and Th17 cytokines, robust expansion of tissue-resident memory T cells, and the formation of inducible bronchus-associated lymphoid tissue (iBALT)-all indicative of potentiated mucosal immunity. These findings highlight a functional role for A. muciniphila not only as a microbial signature of COVID-19-associated dysbiosis but also as an active modulator of host immune responses during respiratory viral infections. These findings position A. muciniphila as both a biomarker of COVID-19-related gut dysbiosis and a potent live biotherapeutic candidate for respiratory infections. Its ability to enhance mucosal immune responses through gut-lung axis modulation highlights its promise in prophylactic strategies against viral respiratory diseases, including SARS-CoV-2."

Nucleotide supplementation may enhance the ability of A. muciniphila to modulate gut mucosal barrier integrity in hyperuricemia patients. *Akkermansia* possesses unique enzymes (\u03b2-N-acetylhexosaminidases) that allow it to colonize the mucosal layer and participate in mucin degradation.\"\n\nThis hypothesis is supported by the literature regarding the efficacy of fermented botanical extracts and specific microbial metabolites in reinforcing gut-lung and gut-kidney axes, though the claim about specific *Akkermansia* enzymatic mechanisms requires nuanced verification.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe restorative potential of the gut-lung and gut-kidney axes in chronic disease management involves leveraging fermented bioactive matrices to overcome nutrient bioavailability barriers. Nutritional interventions, including microbial-fermented phytochemicals and nucleotide supplements, promote gut barrier homeostasis and metabolic remodeling, which are crucial for mitigating systemic inflammation in conditions like COPD and hyperuricemia.\n\n### [INTRODUCTION & JUSTIFICATION]\nChronic obstructive pulmonary disease (COPD) and hyperuricemic nephropathy (HN) are systemic pathologies where gut dysbiosis facilitates disease progression via translocation of pathogen-associated molecular patterns (PAMPs). Fermentation functions as a biotechnological tool to enhance the bioavailability of phytochemicals, facilitating their role as systemic immunometabolic regulators. As stated in the literature, \"The fermented food microbiome comprises live microorganisms, their genetic elements and their metabolites, and represents an established dietary approach for modulating host-microbiome interactions through the consumption of fermented foods.\" This strategy is essential when host digestive capacities are compromised. Furthermore, nucleotide supplementation and specific probiotic strains, such as *Akkermansia muciniphila*, play synergistic roles in reinforcing intestinal barrier integrity, directly influencing pulmonary and renal repair pathways through the modulation of systemic inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation transforms complex phytochemicals, converting glycosides into highly bioavailable aglycones.\n*   The \"pathological circuit\" in lung injury links severe pulmonary inflammation to gut permeability and bacterial translocation, specifically LPS.\n*   *Akkermansia muciniphila* enrichment is consistently associated with mucosal barrier preservation in diverse inflammatory contexts.\n*   Nucleotide supplementation in aquaculture models (coho salmon) indicates a biphasic growth response and improved barrier integrity via NF-\u03baB p65 modulation.\n*   Lactobacillus-fermented products reduce JNK/p38 MAPK pathway activation, providing a direct link between microbial metabolites and anti-inflammatory outcomes in gastric mucosa.\n*   Hyperuricemia-associated renal fibrosis is mediated by the TGF-\u03b21/SMAD3 signaling pathway, which is potentially reversible through probiotic-induced gut-kidney axis modulation.\n*   Co-exposure to microplastics and pesticides induces synergistic toxicity in aquatic species via disruption of the gut-liver axis, which is not strictly predicted by individual pollutant assessments.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence supports that the gut-lung axis is a bidirectional communication highway fueled by microbial metabolites. Fermented plant-derived materials and specific bacterial consortia can restructure the gut microbiota to produce beneficial metabolites (e.g., SCFAs), which in turn support pulmonary homeostasis. While *Akkermansia* is recognized for mucin degradation via specific sulfatases, the claim concerning nucleotide supplementation's role in hyperuricemia-related *Akkermansia* colonization remains an area requiring further direct clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe systemic nature of lung health and repair is intrinsically linked to the intestinal microbiome through the gut-lung axis. The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange. Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA).\n\nMicrobial metabolites, particularly short-chain fatty acids (SCFAs), serve as pivotal signaling molecules delivered by the gut that shape the local respiratory environment. In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate. The structural complexity of plant matrices, when processed via fermentation, enhances their utility as carriers for beneficial bacteria and bioactive compounds. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43 mg/g.\n\nRegarding *Akkermansia muciniphila*, its role in maintaining intestinal homeostasis is well-documented, partially through the production of extracellular vesicles. PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Its colonization is further supported by complex enzymatic adaptations. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Bioavailability through Fermentation:** Fermentation acts as a biological \"pre-digestion\" step that degrades antinutritional factors (e.g., tannins and phytic acid), increasing the bioaccessibility of essential nutrients and potentially enhancing the stability of probiotic strains like *Lactobacillus*.\n*   **Extracellular Vesicle Superiority:** Evidence suggests that extracellular vesicles derived from pasteurized *Akkermansia* (PAEVs) may provide broader protective effects in IBD compared to live bacteria or standard vesicles (AEVs), highlighting a shift toward postbiotic strategies.\n*   **Targeted Urease Inhibition:** Novel compounds like luteolin act as competitive urease inhibitors against *Helicobacter pylori*, providing a mechanism for acid tolerance suppression without the broad-spectrum ecological damage caused by traditional antibiotics.\n*   **Metabolic Signaling Networks:** The cross-talk between the gut and host organs is not just limited to metabolites; it involves direct genomic-metabolic regulation, as demonstrated by models integrating Sirtuin1-dependent transcriptional control with butyrate fluxes.\n*   **Phase-Variable Colonization:** *Akkermansia* colonization is not static; it utilizes epigenetic switches (capsular phase variation) to adapt its ecological niche within the mucus layer, balancing planktonic and biofilm states.\n*   **Radioprotection via Bile Acids:** Flavonoids like Taxifolin can reshape the gut microbiota to promote specific bile acid production, which subsequently activates the FXR signaling axis to suppress radiation-induced inflammation.\n*   **Sex-Dimorphic Responses:** Some interventions, such as taurine supplementation for intestinal/cognitive resilience, exhibit sexually dimorphic immune responses, mandating a sex-stratified approach for future therapeutic development.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"COPD Related Alveoli and Lung Microbiome Axis Restoration Hypothesis: The use of 'pre-digested' (fermented) plant-based nutritional additives as a means to circumvent the bioavailability paradox in patients with gut dysbiosis, effectively using botanical matrices as drug-delivery vehicles. Nucleotide supplementation may enhance the ability of *Akkermansia* muciniphila to modulate gut mucosal barrier integrity in hyperuricemia patients. *Akkermansia* possesses unique enzymes (\u03b2-N-acetylhexosaminidases) that allow it to colonize the mucosal layer and participate in mucin degradation.\"\n\nThe hypothesis that fermented nutritional additives circumvent bioavailability limitations in COPD/dysbiosis is supported by substantial evidence. However, while *Akkermansia muciniphila* is widely documented to thrive on mucin glycans, the specific claim regarding its possession of \u03b2-N-acetylhexosaminidases as the unique colonization mechanism is not explicitly detailed within the provided literature; the text confirms its reliance on mucin glycans but lacks specific enzyme mapping. Furthermore, evidence regarding the specific impact of \"nucleotide supplementation\" on *Akkermansia*-mediated barrier integrity in hyperuricemia is insufficient in the provided literature.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nFermented plant-based nutritional additives represent a viable strategy to enhance the bioavailability of bioactive compounds and support gut-lung axis homeostasis in COPD patients by reshaping the gut microbiome and modulating systemic inflammation. While *Akkermansia muciniphila* is established as a key modulator of the intestinal barrier and metabolic health, the explicit enzymatic characterization and the efficacy of direct nucleotide supplementation require further targeted clinical validation within the provided dataset.\n\n### [INTRODUCTION & JUSTIFICATION]\nChronic obstructive pulmonary disease (COPD) and hyperuricemia (HUA) are increasingly viewed as systemic conditions linked by gut microbiota dysbiosis and barrier dysfunction. Botanical matrices, when processed through fermentation, overcome limitations of poor bioavailability. \"Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects.\" The utilization of these food-based matrices acts as a delivery system, where \"Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites.\" *Akkermansia muciniphila* is central to this paradigm, as \"AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage.\" Further, the therapeutic impact of such interventions is often dependent on the matrix, as \"Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses.\" \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation enables the transformation of plant-derived phytochemicals into more bioavailable forms, such as aglycones, which are essential for systemic therapeutic efficacy.\n*   *Akkermansia muciniphila* plays a dual role in hyperuricemia and COPD, serving as both a biomarker of health and a therapeutic agent that supports barrier integrity.\n*   Colloidal delivery systems for bioactive compounds, such as curcumin, significantly influence their spatiotemporal accumulation in the gut and subsequent microbial modulation.\n*   The \"gut-lung axis\" is not merely an immunological pathway; it is a metabolic rheostat fueled by short-chain fatty acids (SCFAs) and tryptophan metabolites.\n*   Heat-inactivated *Akkermansia muciniphila* (postbiotics) exhibits therapeutic potential comparable to live bacteria in modulating uric acid metabolism and inflammatory pathways.\n*   Cisplatin-induced nephrotoxicity represents another systemic disease context where gut-kidney axis modulation via polysaccharides mimics gut-lung axis dynamics.\n*   The use of probiotics, such as *Lactobacillus* species, provides an adjunctive therapy to reduce emphysema and inflammation in COPD by restoring microbial diversity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment."

To begin to address this gap in knowledge, we developed an online survey to assess participant familiarity with different types of fermented products, determine consumption frequency, and gain insight into the motivation for consumption. A total of 751 participants completed the survey. Yogurt was the most frequently identified fermented food (n\u202f=\u202f658; 87.62% of respondents). Participants reported consuming fermented cereal grains (n\u202f=\u202f307; 46.17%), fruits and vegetables (n\u202f=\u202f281; 42.26%), dairy products (n\u202f=\u202f204; 39.70%), soy/rice products (n\u202f=\u202f250; 37.60%) and fermented meats (n\u202f=\u202f204; 30.68%). Reported daily consumption was highest for categories of fermented cereal and dairy products, compared to the other categories which typically were consumed on a weekly or monthly basis. The primary motivator for consumption was taste (n\u202f=\u202f337; 50.68%) compared to health benefits (n\u202f=\u202f235; 35.34%) and cultural reasons (n\u202f=\u202f80; 12.03%).

Participants associated health benefits with all fermented products listed in the survey. Therefore, consumers may assume that all fermented foods confer the same health benefits. The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved."

However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity."

In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

However, the mechanisms through which 3'-SL alleviates antibiotic-associated diarrhea remain poorly understood. In this study, an antibiotic-associated diarrhea model was established through the co-administration of ampicillin and neomycin. The effects of 3'-SL supplementation on diarrhea phenotype, inflammation, intestinal permeability, and barrier function were examined in antibiotic-associated diarrhea-model mice. Moreover, gut microbiota composition, metabolite profiles, and their alterations were analyzed using genomic and metabolomic approaches. The results demonstrate that 3'-SL increased body weight and aquaporin (AQP) 3 and AQP4 levels but reduced diarrhea rate, cecal mass, and fecal water content in the model mice, indicating its therapeutic effect on diarrhea. Furthermore, 3'-SL reduced serum levels of IL-6, tumor necrosis factor (TNF)-\u03b1, and IL-1\u03b2, while increasing IL-10 levels in the mice. Moreover, 3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice. 16S rRNA analysis revealed that mice in the 3'-SL group exhibited greater abundances of Akkermansia, Bacteroides, and Dubosiella, along with a reduced relative abundance of the diarrhea-associated bacterium Alloprevotella. Furthermore, metabolomics analysis indicated that 3'-SL promoted enrichment of purine metabolism, pyrimidine metabolism, nucleotide metabolism, and the pentose phosphate pathway, which may be associated with diarrhea development, inflammation amelioration, and barrier regulation. In conclusion, our findings suggest that 3'-SL ameliorates antibiotic-associated diarrhea by modulating gut microbiota and metabolite profiles."

Multiple studies have shown that Akkermansia muciniphila, as a promising beneficial gut bacterium, is robustly associated with positive effects on host metabolism, immunological regulation, and its presence inversely correlates with body weight. But the precise function played by this bacterium underlying lipid degradation is still unknown. Here we identify a metallophosphoesterase from A. muciniphila. The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies."

Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount.

In this study, 50 LAB strains previously isolated from Korean traditional fermented foods and obtained from the National Agrobiodiversity Center (KACC, Jeonju-si, Republic of Korea) were systematically screened for bifunctional carbohydrate and protein degradation capacities, and their potential to improve the nutritional functionality of wheat bran was evaluated. Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations."

The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival.

Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD."

However, their broader use in food formulations is often limited by the presence of anti-nutritional factors (ANF) and other compounds that may negatively affect digestibility, technological performance, and sensory acceptability.

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach.

This study investigated the synergistic effects and underlying mechanisms of polystyrene NPs and ABM at environmentally relevant concentrations in juvenile rainbow trout (Oncorhynchus mykiss) during a 28-day exposure. Compared to ABM alone, co-exposure with NPs induced significantly greater synergistic toxicity. This was evidenced by exacerbated intestinal barrier dysfunction, including downregulation of tight junction proteins (Occludin, Claudin-23, ZO-1) and a shift in the gut microbiota characterized by the enrichment of potential pathogens, such as Neochlamydia. In the liver, the combined exposure markedly enhanced oxidative stress and inflammatory responses. Untargeted metabolomics further revealed that the co-exposure disturbed fundamental metabolic pathways more profoundly than either contaminant alone, particularly affecting amino acid, carbohydrate, and nucleotide metabolism. Critically, correlation analyses integrated gut microbiota dysbiosis with hepatic metabolic disorders, supporting a pivotal role for gut-liver axis disruption in the synergistic toxicity.

Natural polysaccharides-high-molecular-weight carbohydrate polymers derived from plants, fungi, marine organisms, and animal sources-have emerged as a promising class of multi-target bioactive agents for T2DM management. This comprehensive review first outlines the key pathophysiological mechanisms of T2DM, encompassing insulin resistance, pancreatic \u03b2-cell dysfunction, chronic inflammation, oxidative stress, and gut microbiota dysbiosis. We then systematically review the natural sources and structural classification of polysaccharides, alongside their extraction and purification methods. The core of this review examines the molecular mechanisms by which natural polysaccharides ameliorate T2DM: (1) enhancing insulin sensitivity and glucose metabolism via the PI3K/Akt and AMPK signaling pathways; (2) protecting pancreatic \u03b2-cells from apoptosis and promoting insulin secretion; (3) suppressing chronic inflammation through NF-\u03baB and NLRP3 pathway inhibition; (4) attenuating oxidative stress via Nrf2/HO-1 pathway activation; and (5) restoring gut microbiota homeostasis, reinforcing intestinal barrier integrity, and elevating short-chain fatty acids production. Structure-activity relationship analyses indicate that hypoglycemic efficacy is tightly correlated with molecular weight, monosaccharide composition, glycosidic linkage types, degree of branching, three-dimensional conformation, and chemical derivatization. Finally, challenges surrounding clinical translation, standardization, and bioavailability are discussed, along with future research directions. This review provides a theoretical framework for the application of natural polysaccharides as functional foods, nutraceuticals, or lead compounds in T2DM prevention and treatment."

Furthermore, nucleotide supplementation and specific probiotic strains, such as *Akkermansia muciniphila*, play synergistic roles in reinforcing intestinal barrier integrity, directly influencing pulmonary and renal repair pathways through the modulation of systemic inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation transforms complex phytochemicals, converting glycosides into highly bioavailable aglycones.\n*   The \"pathological circuit\" in lung injury links severe pulmonary inflammation to gut permeability and bacterial translocation, specifically LPS.\n*   *Akkermansia muciniphila* enrichment is consistently associated with mucosal barrier preservation in diverse inflammatory contexts.\n*   Nucleotide supplementation in aquaculture models (coho salmon) indicates a biphasic growth response and improved barrier integrity via NF-\u03baB p65 modulation.\n*   Lactobacillus-fermented products reduce JNK/p38 MAPK pathway activation, providing a direct link between microbial metabolites and anti-inflammatory outcomes in gastric mucosa.\n*   Hyperuricemia-associated renal fibrosis is mediated by the TGF-\u03b21/SMAD3 signaling pathway, which is potentially reversible through probiotic-induced gut-kidney axis modulation.\n*   Co-exposure to microplastics and pesticides induces synergistic toxicity in aquatic species via disruption of the gut-liver axis, which is not strictly predicted by individual pollutant assessments.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, the mechanistic basis linking dietary MP exposure to gut dysbiosis and intestinal dysfunction remains poorly resolved, limiting robust human health risk assessment. This review critically synthesizes current evidence on foodborne MPs, dietary exposure, and the physicochemical determinants of gastrointestinal fate, bioavailability, and toxicity. We examine the molecular and microbiome-mediated mechanisms linking MPs exposure to intestinal dysbiosis, barrier dysfunction, oxidative stress, immune activation, and metabolic reprogramming. Particular attention is given to the role of MPs as vectors for co-contaminants, which can amplify toxicity through synergistic interactions and reshape host-microbiome responses. We highlight advances in dynamic colon simulation and integrated multi-omics that unravels the mechanism underlying MP-induced intestinal toxicity. Current evidence indicates that gut microbiome dysregulation is a key mechanism driving foodborne MP-induced intestinal dysfunction and systemic toxicity. This review integrates multidisciplinary evidence to identify critical knowledge gaps and guide future research on the mechanisms, exposure, and health risks of foodborne microplastics.\n\nID: 42563498\nTitle: From Gut to Heart: The Emerging Role of Dietary Fermentable Fiber in Heart Failure with Preserved Ejection Fraction.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is a multisystemic syndrome that accounts for more than half of all heart failure cases and causes a substantial burden of morbidity and mortality. In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF.\n\nID: 42561489\nTitle: Neuroimmune mechanisms of the gut-brain axis in treatment-resistant depression: Implications for microbiome-based therapeutic strategies.\nAbstract: Treatment-resistant depression (TRD) represents a major clinical challenge characterised by inadequate response to conventional antidepressant therapies and high relapse rates. Emerging evidence suggests that TRD may extend beyond monoaminergic dysfunction and may involve dysregulation of the HPA axis, neuroinflammation, impaired neuroplasticity, and disruption of the gut-brain axis (GBA). Gut dysbiosis has been associated with treatment resistance through alterations in monoamine turnover, immune signalling, intestinal barrier integrity, and drug-microbiome interactions affecting antidepressant bioavailability. This review integrates emerging evidence supporting targeted modulation of the GBA as a mechanistically informed strategy for TRD. Specific microbial strains (e.g., Christensenella minuta, Akkermansia muciniphila, Bifidobacterium breve CCFM1025), microbial metabolites (e.g., indole-3-propionic acid, indole-3-lactic acid, anserine), and phytochemicals (e.g., curcumin, matrine, salidroside) are discussed for their proposed roles in modulating neuroendocrine signalling, neuroinflammation, and synaptic plasticity. The review also highlights emerging peripheral biomarkers, including the kynurenine/tryptophan ratio, serum metabolomics, and lymphocyte serotonin transporter clustering, as candidate tools for stratified psychiatry. Most of the evidence discussed in this review comes from animal studies, in vitro systems, and computational analyses, while direct evidence in patients with treatment-resistant depression remains limited. These findings provide important mechanistic insights into gut-brain axis dysfunction but require further validation in human TRD populations. Biomarker-guided and endotype-based approaches targeting the gut-brain axis may offer a useful framework for future research, although their clinical utility has yet to be established.\n\nID: 42553088\nTitle: Molecular insights into lower respiratory tract microbiota reveal disease-specific biomarkers and shared microbial networks in asthma and COPD.\nAbstract: Lower respiratory tract infections (LRTIs) exacerbate chronic airway diseases, yet phenotype-specific microbial signatures are poorly defined. We applied broncho-alveolar lavage fluid (BALF) genomic sequencing to identify biomarkers for asthma and chronic obstructive pulmonary disease (COPD). Between December 2023 and February 2025, 1-146 adults with suspected LRTI enrolled from the First Hospital of Jilin University underwent BALF next-generation sequencing. Patients were stratified by lung function, with the impaired pulmonary function group further divided into asthma, COPD-mild-moderate, and COPD-severe subgroups. Disease-specific key biomarkers were identified using machine learning algorithms and analyzed for co-occurrence. Impaired pulmonary function was not only associated with pathogenic microorganisms and its higher microbial burden, but also associated with a distinct community structure. Random forest models revealed disease-specific biomarkers, with Prevotella intermedia, Finegoldia magna, and Human parvovirus enriched in asthma, Veillonella parvula, Human respiratory syncytial virus, and Haemophilus influenzae enriched in COPD-mild-moderate, and Human respiratory syncytial virus, Human coronavirus, and Human parainfluenza virus enriched in COPD-severe. Co-occurrence network identified hubs linking asthma-centric (Haemophilus parainfluenzae and Schaalia odontolytica) and COPD-centric (Klebsiella pneumoniae, Veillonella parvula, and Streptococcus constellatus) clusters, suggesting potential cross-phenotype microbial crosstalk. Genomic sequencing profiling delineates distinct yet overlapping airway microbiota across separate pulmonary dysfunctional diseases - asthma and COPD. Compact biomarker panels classify each condition accurately and reveal shared microbial hubs that may drive chronic inflammation and exacerbations, supporting microbiome-guided precision diagnostics and therapy.\n\nID: 42549852\nTitle: Dynamic Changes in Airway Microbiota and Immune Homeostasis in Patients With COPD and the Implications for Nursing Management.\nAbstract: To investigate changes in airway microbiota and immune markers across Chronic Obstructive Pulmonary Disease (COPD) stages and their associations with clinical phenotypes and nursing factors, providing a basis for precision nursing. 284 stable COPD patients (GOLD 2-3) were enrolled. Sputum and clinical data were collected at baseline (T0), exacerbation (T1), and recovery (T2). Microbiota structure was analyzed via 16S rRNA sequencing, and levels of immune markers such as interleukin-8 (IL-8) and IL-1\u03b2 were measured by Enzyme-Linked Immunosorbent Assay (ELISA). Statistical analysis was performed by integrating clinical scale scores and nursing adherence data. At T1, airway microbial \u03b1 diversity was remarkably lower than at T0 and T2 (p < 0.01). The relative abundances of Haemophilus and Prevotella increased, while those of Veillonella and Lactococcus decreased (p < 0.01). Levels of IL 8, IL 1\u03b2, and TNF \u03b1 were elevated, and Secretory Leukocyte Protease Inhibitor (SLPI) levels were reduced at T1 (p < 0.01). Notable correlations were found between microbiota and immune markers (e.g., Haemophilus abundance with IL 8 levels, r = 0.52, p < 0.01), and these were positively associated with clinical scores such as COPD Assessment Test (CAT) and St. George's Respiratory Questionnaire (SGRQ) (p < 0.05). Patients with >80% inhaler adherence and regular breathing exercises/nutrition had higher microbial diversity and attenuated inflammation (p<0.05). The airway microbiota-immune axis in COPD patients demonstrates a disease stage-dependent imbalance, characterized by microbial dysbiosis and enhanced pro-inflammatory responses during acute exacerbation. Good nursing adherence can modulate this axis's homeostasis, offering novel targets for precision nursing.\n\nID: 42543328\nTitle: [Role of \"gut lung axis-NETs\" pathway in chronic obstructive pulmonary disease based on theory of \"deficiency, phlegm, stasis, and toxin\"].\nAbstract: Chronic obstructive pulmonary disease(COPD) is a systemic disease characterized by persistent airflow limitation and airway inflammation, with a consistently high incidence and a lack of effective clinical interventions to reverse disease progression. Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD.\n\nID: 42542225\nTitle: Micro(nano)plastics as dynamic vectors for hazardous agents: Bridging environmental transport to health impacts.\nAbstract: The pervasive accumulation of micro(nano)plastics (MNPs) in the environment establishes them as persistent contaminants, posing a significant threat to ecosystem integrity and human health. This review synthesizes the environmental journey of MNPs by framing them as dynamic colloidal particles and mechanistically tracing their pathway from source to biological uptake. We discuss fundamental interfacial processes, including DLVO and non-DLVO interactions, straining, and air-water interface capture, governing MNP mobility and retention in porous media. These processes control MNP dispersal and potential to contaminate groundwater and agricultural systems. The interplay of colloidal properties (size, shape, surface chemistry) with environmental parameters is examined to explain exposure routes. We also detail how this colloidal behavior dictates bioavailability, facilitating MNP uptake in plants and soil fauna and amplifying their role as vectors for co-contaminants and antibiotic resistance genes. Human biomonitoring studies reveal MNPs in blood, stool, placenta, and bronchoalveolar lavage fluid. Systematic review evidence indicates associations with cardiovascular inflammation, endothelial dysfunction, and fibrosis; in vitro studies demonstrate PS MP-induced reductions in human sperm motility, vitality, and fertility-related gene expression; and cross-sectional studies link higher fecal MNP concentrations to gut microbiota dysbiosis, including increased abundance of harmful bacteria and decreased beneficial taxa. However, causation remains unestablished due to methodological heterogeneity and the predominance of cross-sectional designs. By integrating colloid science with ecotoxicology and exposure science, this review bridges the gap between MNP physical transport and adverse health outcomes, provides a framework for risk assessment, and highlights urgent research priorities, including standardized methods, longitudinal studies, and human-relevant models.\n\nID: 42541365\nTitle: The gut microbiome and drug-resistant epilepsy: Microbiome-antiseizure medication interactions and implications for pharmacoresistance.\nAbstract: Drug-resistant epilepsy (DRE) affects approximately one-third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a potentially modifiable factor that may function as a systems-level modifier of these established mechanisms rather than a standalone pathway. The gut microbiome harbors a vast repertoire of drug-metabolizing enzymes capable of directly biotransforming orally administered antiseizure medications (ASMs)-including valproic acid, lamotrigine, carbamazepine, and oxcarbazepine-thereby altering their pharmacokinetics, bioavailability, and therapeutic efficacy. Additionally, microbial metabolites modulate host cytochrome P450 enzymes, nuclear receptors, and efflux transporters such as P-glycoprotein, while bacterial \u03b2-glucuronidases influence the enterohepatic recirculation of glucuronidated ASMs. Conversely, chronic ASM exposure reshapes the gut microbial ecosystem, creating a self-perpetuating cycle of dysbiosis and pharmacoresistance. This narrative review synthesizes current evidence on microbiome-ASM interactions in DRE, proposes a concrete experimental pipeline for characterizing ASM-specific microbial biotransformation, and outlines a framework for integrating physiologically based pharmacokinetic modeling with microbiome data. We discuss clinical implications for epileptologists-including the role of therapeutic drug monitoring in detecting microbiome-mediated pharmacokinetic variability, the concept of microbiome-neutral ASM selection, and earlier deployment of the ketogenic diet as a microbiome-targeted intervention. We highlight the translational potential of pharmacomicrobiomics-the study of how microbiome variation influences drug disposition and response-and identify critical knowledge gaps that warrant future investigation. PLAIN LANGUAGE SUMMARY: About one in three people with epilepsy continue to have seizures despite treatment. This review summarizes growing evidence that the gut microbiome-the community of bacteria living in the intestines-can influence how seizure medications work by altering their absorption, metabolism, and clearance. The medications themselves can reshape the microbiome in return, creating a cycle that may sustain treatment failure. Understanding this gut-drug relationship may open new paths to personalized epilepsy care through diet, probiotics, and microbiome-guided prescribing.\n\nID: 42528645\nTitle: Gut microbiota dysbiosis in COPD patients increases the level of queuine in the blood serum abnormally enhancing the viability of lung epithelial cells.\nAbstract: To investigate the association between gut-airway microbiota dysbiosis, serum queuine levels, and early malignant transformation in patients with chronic obstructive pulmonary disease (COPD). We further explored whether the potential mechanistic role of queuine in enhancing lung epithelial cell viability under cigarette smoke exposure. Stable COPD patients were stratified into a high relative abundance of Proteobacteria group (CH) and a low relative abundance of Proteobacteria group (CL) using 16S rRNA gene sequencing of fecal samples. Airway microbiota profiles were analyzed in parallel to assess gut-lung axis coupling. Serum queuine concentrations were quantified using LC-MS/MS in healthy controls, COPD subgroups (CL and CH), and COPD patients complicated by lung cancer. Clinical symptoms (CAT, mMRC, SCSS) and spirometry (FEV1/FVC, FEV1, FEV1% predicted, FVC, FEF25-75%) were assessed. In vitro experiments were performed using cigarette smoke extract (CSE)-stimulated lung cancer epithelial A549 cells and bronchial epithelial BEAS-2B cells to determine the effects of queuine on cell viability. Chest CT imaging was analyzed to quantify pulmonary nodules as an indicator of in vivo epithelial proliferative activity. The \u03b1-diversity of gut microbiota did not differ between CH and CL. In contrast, \u03b2-diversity showed separation (PERMANOVA P\u00a0=\u00a00.062), with CH characterized by Proteobacteria enrichment and relative depletion of Firmicutes, Bacteroidota, and Actinobacteriota. Airway communities showed concordant remodeling with shifts in taxa consistent with dysbiosis. Serum queuine concentrations increased stepwise from healthy controls to COPD, were higher in CH than CL, and were highest in COPD complicated by lung cancer. Despite comparable pulmonary function and symptom scores between CH and CL groups, the CH group exhibited a significantly higher number of pulmonary nodules on CT imaging, particularly ground-glass nodules. In vitro, queuine significantly enhanced the viability of CSE-stimulated A549 lung cancer cells but failed to rescue CSE-induced growth inhibition in BEAS-2B cells. COPD-associated gut microbiota dysbiosis, particularly enrichment of Proteobacteria, is closely associated with elevated systemic queuine levels. Excess queuine enhances cell viability of smoke-exposed lung cancer epithelial cells and is associated with increased pulmonary nodules in vivo. These findings identify queuine as a microbiota-derived metabolic mediator that may connect COPD-related dysbiosis to abnormal proliferation of lung epithelial cells.\n\nID: 42526595\nTitle: Taurine mitigates intestinal injury and spatial memory deficits induced by high-fat diet and abdominal irradiation.\nAbstract: Combined metabolic dysfunction and ionizing radiation produce multifactorial systemic harm, challenging organismal homeostasis and cognitive function. Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders.\n\nID: 42523106\nTitle: The associations of human genetic variations with airway microbiome, environmental exposures, and respiratory health.\nAbstract: The intricate interactions between environmental exposures, the respiratory microbiome, and host genetic variations remain inadequately understood in the context of respiratory health. This study utilized sputum metagenomic data from 1,651 individuals in our previous cohort to elucidate these associations. Mendelian randomization indicated that air pollutants (e.g., SO2, CO, and PM2.5) were associated with lung function, which is potentially mediated by microbes, such as Actinomyces, Haemophilus influenzae, and Veillonella spp. Several genetic loci associated with respiratory microbiome variation were found to be linked to genotype-dependent associations between environmental exposures and lung function. For bacteria, the MEOX1 locus (rs1973191819) was associated with lower Filifactor alocis abundance under air pollutant exposure. The FAM110D (1:26157175) and USP36 (rs1343834070) loci showed associations with higher levels of certain pathogenic taxa (e.g., Ralstonia pickettii, Neisseria) and lower levels of the commensal Oribacterium, increasing chronic obstructive pulmonary disease (COPD) risk. For fungi, DNAJC18 and CCDC57 loci exhibited associations with Candida and Penicillium abundance, respectively. These genotype-dependent associations between the microbiome and environmental exposures provide insights into airway dysbiosis and susceptibility to respiratory diseases. This study reveals why individuals exposed to identical air pollution exhibit varying degrees of respiratory severity, pointing to a critical missing link: our genetics. While pollution is a known disease trigger, our findings demonstrate that host genetic variation actively regulates and shapes the respiratory microbiome under environmental stress. By mapping specific genetic loci to pollutant-driven bacterial shifts, this work elucidates how host genetics filters environmental risks to govern microbial homeostasis. These results underscore the necessity of incorporating host-microbiome genetic regulation into environmental health research. Ultimately, this study shifts the paradigm toward personalized medicine, enabling the early identification of at-risk individuals and the development of targeted, microbiome-informed interventions.\n\nID: 42521224\nTitle: Gut microbiota and iron deficiency anemia: Mechanisms, microbial signatures, and dietary interactions (A narrative review).\nAbstract: Iron deficiency anemia (IDA) is one of the most prevalent micronutrient disorders worldwide. Recent work suggests that dysbiosis may not simply be a consequence of low iron status but may actively contribute to impaired absorption. This narrative review synthesizes the evidence on gut microbiota patterns in IDA across age groups, examines the mechanistic links between dysbiosis and iron metabolism, and identifies the potential roles of microbiota-related dietary and therapeutic strategies. This narrative review used a selective, theory-driven approach, based on targeted searches of PubMed, Scopus, and Web of Science (2005-2026), to synthesize heterogeneous human, experimental, and mechanistic evidence on gut microbiota-iron interactions in iron deficiency anemia (IDA). Evidence suggests a bidirectional, context-dependent relationship between IDA and gut microbiota involving host iron regulation, microbial competition, metabolites, and diet. Individuals with IDA often show reduced microbial diversity, depletion of SCFA-producing taxa, and enrichment of iron-scavenging bacteria, although direct causal evidence in humans remains limited. IDA is commonly associated with recurring dysbiosis patterns characterized by reduced short-chain fatty acid-producing commensals and relative enrichment of inflammatory, iron-competitive taxa. While iron supplementation remains the cornerstone of evidence-based IDA management, the ecological effects of unabsorbed luminal iron on gut microbial communities support the concept of a potential \"iron paradox,\" particularly in inflammatory or high-infection settings. Therefore, microbiota-targeted strategies should currently be regarded as hypothesis-generating concepts rather than established clinical interventions and require further mechanism and clinical validation.\n\nID: 42514322\nTitle: Urolithins at the Crossroads of Gut Inflammation and Cancer-A Narrative Review.\nAbstract: Chronic inflammation and the associated dysbiosis of the gut microbiota are increasingly recognized as key factors contributing to the development of inflammatory bowel disease (IBD) and colorectal cancer (CRC). The diet-gut microbiota-immune system-cancer axis is considered a key regulator of these processes. Among the bioactive compounds found in the diet, ellagitannins have garnered significant scientific interest due to their conversion by the gut microbiota into biologically active metabolites known as urolithins. Urolithin A (UroA), one of the best characterized compounds, exhibits broad anti-inflammatory, antioxidant, immunomodulatory, and anticancer properties. It modulates signaling pathways associated with inflammation, oxidative stress, mitochondrial dysfunction, and cell proliferation. Furthermore, UroA has been shown to improve intestinal barrier integrity, regulate immune cell activity, and induce mitophagy, thereby contributing to the restoration of mitochondrial and cellular homeostasis. A growing body of evidence also suggests that UroA may inhibit cancer cell proliferation, induce apoptosis, and disrupt the molecular pathways involved in colorectal carcinogenesis. This review summarizes the current state of knowledge regarding the biosynthesis and bioavailability of UroA, its molecular mechanisms of action in IBD, and its potential role in the prevention and treatment of CRC. Furthermore, the limitations of UroA-based therapies and future research directions are discussed. Although further, well-designed clinical trials are necessary, current findings suggest that UroA may represent a promising microflora-targeted therapeutic strategy in chronic inflammatory and CRC diseases.\n\nID: 42514077\nTitle: The Gut-Lung Microbiome Axis in Alveolar Stem Cell Regeneration and Lung Repair.\nAbstract: The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange. Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair.\n\nID: 42513562\nTitle: Microbiome-Targeted Modulation in Renal Transplantation.\nAbstract: The gut microbiome has emerged as a critical determinant of health and disease across virtually all organ systems. In the context of chronic kidney disease (CKD) and renal transplantation, mounting evidence reveals a complex bidirectional relationship between the intestinal microbiota and kidney function-commonly referred to as the gut-kidney axis. Patients with CKD harbor a profoundly altered gut microbial ecosystem characterized by reduced diversity, depletion of beneficial commensal organisms, and expansion of pathobiont taxa capable of generating uremic toxins and pro-inflammatory mediators. These perturbations are further compounded by the uremic milieu itself, dietary restrictions, frequent antibiotic exposure, and the use of immunosuppressive agents following transplantation. The gut-liver-kidney axis adds an additional layer of complexity, linking hepatic metabolism, bile acid signaling, endotoxemia, and systemic immune activation to the progression of renal disease. Gut-derived metabolites-including short-chain fatty acids (SCFAs), bile acids, trimethylamine N-oxide (TMAO), and tryptophan-derived uremic solutes such as indoxyl sulfate and p-cresyl sulfate-serve as molecular mediators of inter-organ crosstalk and have been identified as both biomarkers and therapeutic targets. A growing body of literature supports the diagnostic and prognostic utility of microbiome composition and its metabolic signatures in patients with CKD and those undergoing renal replacement therapy. Therapeutic strategies aimed at restoring microbial homeostasis-encompassing dietary interventions, prebiotics, probiotics, synbiotics, fecal microbiota transplantation (FMT), bile acid-based therapies, and novel pharmacological approaches-hold considerable promise for improving outcomes in CKD and transplant recipients. Importantly, the bidirectional relationship between immunosuppressive drugs and the gut microbiota has emerged as a clinically significant determinant of both microbial ecology and drug pharmacokinetics: each major immunosuppressive agent class-corticosteroids, calcineurin inhibitors, mycophenolate mofetil, and mTOR inhibitors-induces characteristic dysbiotic patterns, while in turn, the microbiota modulates drug bioavailability through enzymatic biotransformation (notably bacterial beta-glucuronidase activity affecting mycophenolic acid enterohepatic recirculation) and modulation of host drug-metabolizing enzymes. This narrative review provides a comprehensive overview of the current understanding of microbiome dysbiosis in the setting of renal disease and transplantation, examines the mechanistic underpinnings of the gut-liver-kidney axis, details the multifaceted impact of dysbiosis on transplant outcomes-including allograft function and rejection, infection, post-transplant diabetes, and cardiovascular complications-and critically appraises the translational potential of microbiome-targeted interventions. We conclude by highlighting ongoing challenges and future directions toward personalized, microbiome-informed clinical care.\n\nID: 42511204\nTitle: Postbiotics in Functional Foods: Preparation-Based Characterization, Gut-Brain Axis Interactions, and Translational Perspectives.\nAbstract: Postbiotics are defined as preparations of inanimate microorganisms and/or their components that confer a health benefit on the host. Although interest in postbiotics has increased substantially, their translational use in functional foods remains insufficiently characterized with respect to preparation identity, production methodology, food-matrix compatibility, mechanistic specificity, and regulatory positioning. This PRISMA-guided structured review aims to synthesize current evidence on postbiotics in functional food and nutraceutical contexts, with particular emphasis on preparation-based characterization, gut-brain axis-related mechanisms and clinical findings, food matrix applicability, and regulatory and health-claim considerations. Unlike broader postbiotic reviews that mainly address definitions, general health effects, or technological stability, this review integrates preparation identity, production process, gut-brain axis-related evidence, food matrix compatibility, and regulatory/health-claim translation within a single functional food framework. A structured literature search was conducted in Scopus and Web of Science Core Collection and was completed on 16 February 2026. The search strategy included three conceptual blocks: postbiotic and inactivation-based preparation terms, functional food/nutraceutical and food matrix terms, and gut-brain axis-related clinical and mechanistic terms. Cosmetic, topical, veterinary, animal feed, and aquaculture-focused publications were excluded. The export files contained 131 records from Scopus and 136 from the Web of Science Core Collection, yielding 267 records after applying document-type and language filters. After manually removing duplicates, 237 unique records were screened. Following title/abstract screening, 176 records were excluded as outside the scope of the review, and 61 publications were retained for full-text assessment and final thematic synthesis. The review was reported according to applicable PRISMA 2020 items. The evidence was organized into three thematic domains: gut-brain axis-related clinical findings, mechanistic evidence, and food matrix/product development applications. Heat-inactivated preparations, including Lactobacillus gasseri CP2305 and Lactiplantibacillus plantarum SNK12, have shown preliminary effects on stress-related symptoms, sleep quality, and selected neuroendocrine or inflammatory biomarkers in human studies. Mechanistic pathways include gut barrier integrity, immunomodulation, short-chain fatty acid signaling, tryptophan-kynurenine-serotonin metabolism, vagal communication, and regulation of the hypothalamic-pituitary-adrenal axis. Food matrix studies support the potential application of postbiotics in fermented dairy products, cereal-based systems, plant-based matrices, powders, concentrates, and bioactive packaging; however, matrix-dependent effects on bioavailability, sensory quality, and biological activity remain incompletely defined. Postbiotics provide a stable translational platform for functional-food development, but their scientific and commercial use requires clear characterization of the microbial source, production process, inactivation method, retained active fractions, dose metric, delivery matrix, and clinically meaningful endpoint. Future studies should avoid broad category-level claims and prioritize preparation- and matrix-defined human evidence with standardized safety reporting.\n\nID: 42509759\nTitle: Mulberry, Gut Microbiota and Gut Functionality: Effects Shaped by Raw Material and Processing Methods.\nAbstract: Mulberry species (Morus spp.) provide phytochemically distinct plant materials in which leaves are typically characterized by high levels of iminosugars (notably 1-deoxynojirimycin), flavonols/flavones, and polysaccharides, whereas fruits-especially Morus nigra-contain substantial amounts of anthocyanins alongside other phenolic compounds and polysaccharides. Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health.\n\nID: 42504192\nTitle: Construction and Validation of a Machine Learning Model Based on Clinical and Microbiomic Features for Predicting High Mucus Secretion in COPD.\nAbstract: To evaluate clinical and airway microbiome features of excessive mucus secretion (CMH) in COPD progression and apply machine learning for CMH status identification. A total of 319 COPD patients from Changzhi People's Hospital (May 2020-March 2024) were consecutively enrolled and divided by sputum volume and characteristics into a high mucus secretion group (n=173) and a non-high mucus secretion group (n=146). Patients were randomly assigned to training (80%) and testing (20%) sets. Airway microbiome structure was analyzed via 16S rRNA sequencing. From clinical and microbiome data, 70 features were extracted. Six machine learning algorithms (SVM, KNN, RF, BN, GBDT, NN) were used to build classification models. Feature selection employed filtering methods, and hyperparameters were optimized by 10-fold cross-validation. Model performance was assessed using sensitivity, specificity, accuracy, and AUC. The CMH group and the non-CMH group differed significantly in a number of factors, including age, the length of the disease, and pulmonary function indices, according to a comparison of baseline patient data. Analysis of airway microbiome characteristics revealed that the CMH group had significantly lower observed ASVs and Shannon indices (p<0.001), along with significant enrichment of potentially pathogenic bacterial genera such as Haemophilus and Pseudomonas. Following feature selection, disease duration, Haemophilus abundance, history of AECOPD, Pseudomonas abundance, and predicted FEV1% were identified as significant predictive factors. With a sensitivity of 0.867, specificity of 0.789, PPV of 0.805, NPV of 0.855, and AUC of 0.911, the Bayesian Network (BN) model outperformed the other six machine learning models on the testing sets; its generalization ability was significantly superior to other algorithms such as SVM and RF. CMH in COPD is linked to airway dysbiosis and pathogen enrichment. The BN model effectively identifies this phenotype with strong generalization ability.\n\nID: 42503325\nTitle: Vitamin B12-mediated microglial immunometabolic reprogramming: A novel mechanistic insight into diabetes-associated cognitive impairment.\nAbstract: Diabetes-associated cognitive impairment (DCI) is an increasingly recognized neurological complication of type 2 diabetes mellitus characterized by chronic neuroinflammation and microglial immunometabolic dysregulation. Vitamin B12 (VB12) deficiency, which is highly prevalent in patients with diabetes, has been strongly associated with cognitive decline, hippocampal atrophy, and white matter injury. Emerging evidence suggests that VB12 plays a critical role in maintaining one\u2011carbon metabolism, mitochondrial function, and redox homeostasis. Mechanistically, VB12 deficiency promotes homocysteine accumulation, disrupts the S-adenosylmethionine/S-adenosylhomocysteine balance, impairs mitochondrial oxidative phosphorylation, and enhances oxidative stress, thereby driving pro-inflammatory microglial activation and sustained neuroinflammation. In addition, gut microbiota dysbiosis, particularly reduced abundance of Akkermansia muciniphila and other VB12-producing bacteria, may further impair VB12 bioavailability and aggravate neuroinflammation through the gut-brain axis. This review summarizes current evidence linking VB12 deficiency to microglial immunometabolic remodeling in DCI and discusses the therapeutic potential of targeting VB12 metabolism and gut microbial ecology for preventing diabetes-related cognitive decline.\n\nID: 42497929\nTitle: Micro- and nanoplastics disrupt the gut-liver-brain axis: mechanisms of multi-organ toxicity in animal models.\nAbstract: Micro- and nanoplastics (MNPs) are ubiquitous environmental contaminants increasingly recognized as potential drivers of systemic toxicity. Growing evidence indicates that MNPs may affect interconnected physiological systems, particularly the gut-liver-brain axis, which integrates metabolic, immunological, and neuroendocrine responses. This review summarizes current knowledge on the effects of MNPs on the gut-liver-brain axis based on animal studies, with emphasis on mechanisms of toxicity and inter-organ communication. Available findings indicate that the gastrointestinal tract is the primary site of interaction, where MNPs induce intestinal barrier disruption, oxidative stress, immune activation, and gut microbiota dysbiosis. These alterations may promote endotoxemia and inflammatory signaling, contributing to hepatic metabolic disturbances, mitochondrial dysfunction, and hepatocellular injury. In parallel, MNPs may affect the central nervous system through neuroimmune responses, altered neurotransmission, blood-brain barrier dysfunction, and gut-brain signaling disturbances. Oxidative stress, chronic inflammation, and disrupted inter-organ communication appear to represent central mechanisms underlying MNPs toxicity. Nanoplastics, due to their higher bioavailability and ability to cross biological barriers, exhibit particularly strong toxic potential. Overall, current evidence supports a systems-level view of MNPs toxicity and highlights the importance of integrative approaches for improving environmental and health risk assessment.\n\nID: 42482939\nTitle: Modulation of gut microbiota and intestinal barrier by lotus seed, jujube, and longan aril in senna leaf-induced diarrhea in mice.\nAbstract: This study aimed to investigate the regulatory effects of lotus seed, jujube, and longan aril on the gut microbiota structure and barrier function in a senna leaf-induced diarrhea mouse model. Diarrhea was induced in ICR mice using senna leaf extract. Mice received aqueous extracts of lotus seed, jujube, or longan aril for treatment. Intestinal motility was assessed through fecal consistency scoring and the charcoal propulsion test. Colon tissues were collected for histopathological examination using H&E staining, as well as immunohistochemical and Western blot analyses of aquaporin 3 (AQP3) and sodium-hydrogen exchanger 8 (NHE8). Gut microbiota composition was analyzed via 16S rRNA sequencing. All three herbal interventions significantly reduced the loose stool rate and diarrhea index (p\u202f<\u202f0.05), inhibiting small intestinal hypermotility. Histological analysis revealed an increase in goblet cell numbers and improved crypt architecture in the colon. Immunohistochemical evaluation indicated downregulation of AQP3 and upregulation of NHE8 expression, which was confirmed by Western blot analysis. 16S rRNA sequencing demonstrated that all treatments restored \u03b1-diversity (Shannon index, p\u202f<\u202f0.05). \u03b2-diversity analysis revealed that longan aril induced a more extensive reshaping of gut microbial community structure compared to lotus seed and jujube, which exhibited a \"phased\" restoration. The relative abundance of potential pathogens (e.g., Akkermansia muciniphila, Citrobacter spp.) significantly decreased, while beneficial short-chain fatty acid-producing bacteria (e.g., Blautia coccoides, Faecalibaculum rodentium, Alloprevotella rava) were enriched. Unique protective taxa, such as nitrogen-fixing Azospirillum and antioxidant Deinococcus, emerged in specific treatment groups. Lotus seed, jujube, and longan aril synergistically alleviated diarrhea via multiple pathways, including modulation of gut microbiota structure, repair of barrier function, balance of water-electrolyte metabolism, and inhibition of intestinal hypermotility. This study provides a scientific foundation for the clinical application of medicinal and edible homology substances, as well as the development of microecological agents.\n\nID: 42465743\nTitle: Engineered Escherichia coli Nissle 1917 secreting anti-TNF-\u03b1 nanobody as a single-strain live biotherapeutic for inflammatory bowel disease.\nAbstract: The rising global incidence of inflammatory bowel disease (IBD) creates an urgent need for safer, gut-targeted therapies. Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment.\n\nID: 42452334\nTitle: The Oral Microbiome-Nitrate-Nitrite-Nitric Oxide Axis and Cardiovascular Health: A Narrative Review.\nAbstract: Background: The oral microbiome has emerged as a potential contributor to cardiovascular physiology through its role in the enterosalivary nitrate-nitrite-nitric oxide pathway. Oral nitrate-reducing bacteria convert dietary nitrate into nitrite, which can subsequently be reduced to nitric oxide, a signaling molecule associated with vascular tone, endothelial function, platelet activity, and blood pressure regulation. Disruption of this pathway has been associated with reduced nitric oxide bioavailability and impaired vascular responses. Methods: This narrative review summarizes current evidence regarding the relationship between the oral microbiome, nitrate metabolism, and cardiovascular function. Relevant literature was identified through searches of PubMed/MEDLINE and Google Scholar up to May 2026. Evidence from mechanistic, observational, and interventional human studies was reviewed and synthesized thematically. Results: Available evidence suggests that oral nitrate-reducing bacteria may influence nitric oxide bioavailability and vascular function. Studies have reported associations between oral microbiome disruption and changes in blood pressure, endothelial responsiveness, plasma nitrite concentrations, and other surrogate cardiovascular markers. However, findings remain heterogeneous and are influenced by factors such as diet, oral hygiene practices, smoking status, medication use, oral health, and underlying cardiometabolic conditions. Most studies are limited by small sample sizes, short intervention durations, and reliance on surrogate outcomes rather than major cardiovascular events. Conclusions: The oral microbiome may influence cardiovascular health through its role in nitrate metabolism and nitric oxide bioavailability. However, current evidence is largely limited to surrogate vascular outcomes, while data on major cardiovascular events remain scarce. Further longitudinal and interventional studies are needed to clarify causality and evaluate microbiome-targeted interventions.\n\nID: 42451043\nTitle: Blueberry Bioactives as Adjunctive Nutritional Strategies for Pediatric Neurodevelopmental and Emotional-Behavioral Health: Mechanisms, Evidence, and Translational Challenges.\nAbstract: The rising prevalence of neurodevelopmental, emotional, and behavioral disorders in children has prompted interest in dietary strategies that target neuroinflammation, oxidative stress, and gut dysbiosis. Blueberries (Vaccinium spp.) contain substantial amounts of anthocyanins and other neuroactive polyphenols that may confer neuroprotective effects. We summarize the literature published between 2016 and 2025 to examine how the bioactives in blueberries affect symptoms relevant to children with diagnosed neurodevelopmental or emotional-behavioral disorders, including ADHD, mood problems, and cognitive difficulties. Mechanistically, anthocyanins appear to modulate gut microbial composition, modulate neuroinflammation and alleviate oxidative stress via the Nrf2 pathway, and support synaptic plasticity and neurogenesis. Clinical trials, although limited in number and sample size, have reported modest improvements in mood and verbal memory in typically developing children and adolescents, with some gains in attention and executive function. However, direct trials in children with diagnosed neurodevelopmental or emotional-behavioral conditions remain scarce. There are substantial hurdles to translating these findings. Anthocyanins have poor physicochemical stability and low bioavailability, and routine food processing degrades their activity. Emerging solutions such as green extraction from agricultural by-products, colon-targeted microencapsulation, and zero-waste engineering could address these limitations. Rigorous randomized controlled trials in children with diagnosed neurodevelopmental or emotional-behavioral disorders are essential, as are advances in food engineering. Both are needed to move blueberry-based interventions from the laboratory to application.\n\nID: 42444969\nTitle: Exercise-induced gut microbiota metabolites and the gut-lung axis: implications for chronic obstructive pulmonary disease.\nAbstract: Chronic obstructive pulmonary disease (COPD) is increasingly recognised as a systemic disorder associated with gut dysbiosis and impaired gutlung communication. COPD-associated gut dysbiosis suggests potential bidirectional interactions between the gut and lung, which may be mediated by circulating immune cells, gut microbiota-derived metabolites and systemic inflammatory mediators. Emerging evidence suggests that exercise may improve COPD-related symptoms and quality of life not only through direct cardiopulmonary adaptations but also by reshaping gut microbiota composition and metabolic function. Microbiota-derived metabolites, including short-chain fatty acids (SCFAs), secondary bile acids (SBAs) and indole derivatives, may act as key mediators linking exercise-induced microbial changes to pulmonary immune regulation, inflammatory signalling, oxidative stress and epithelial barrier integrity. However, current evidence remains fragmented, and the mechanisms by which exercise-responsive microbial metabolites influence COPD-related pulmonary inflammation, barrier dysfunction and immune homeostasis have not been fully clarified. This review synthesises evidence from human studies, animal models and mechanistic investigations to clarify the relationship among exercise, gut microbiota and COPD, with a focus on how exercise-responsive microbial metabolites may contribute to improved pulmonary health. By integrating current evidence within an exercise-gut-lung axis framework, this review provides a mechanistic basis for developing microbiota-targeted exercise strategies for COPD prevention and management.\n\nID: 42436039\nTitle: Fermentation of plant-based foods: Microbial consortia and their impacts on composition, sensory quality, and health benefits of food products.\nAbstract: Fermented plant-based foods have obtained growing interests for their improved nutrition profile, enhanced flavor and taste, as well as their health-promoting properties. Fermentation using lactic acid bacteria (LAB) and yeasts can eliminate antinutritional components and off-flavor compounds present in plant matrices while also generating beneficial metabolites. The interaction between fermentative microbes and plant substrates is dependent on plant matrices, microbial strains, and processing conditions. Accumulating evidence indicates that fermentation modifies the generation, degradation, and bioavailability of food bioactive compounds such as bioactive peptides, vitamins, volatiles, phenolics, phytic acid and phytates, saponins, and raffinose-family oligosaccharides. This chapter reviews and critically examines research data on microbial transformations of bioactive compounds in fermented plant matrices and pinpoints key factors contributing to inconsistent findings. It also identifies key research directions for understanding and applying fermentation-driven changes to improve the nutritional and functional quality of plant-based fermented foods.\n\nID: 42436034\nTitle: Legume fermentation: Nutritional benefits and emerging applications.\nAbstract: Legumes are increasingly recognized as strategic plant-based ingredients due to their high content of proteins with good biological value, dietary fibers, minerals, oligosaccharides, and phenolic compounds. However, their broader use in food formulations is often limited by the presence of anti-nutritional factors (ANF) and other compounds that may negatively affect digestibility, technological performance, and sensory acceptability. In recent years, different technological and biotechnological strategies have been explored to enhance the nutritional and functional properties of legumes and legume-derived ingredients. Among these approaches, fermentation has emerged as a particularly effective and sustainable process widely applied in several traditional food systems. The use of selected lactic acid bacteria and fermentation processes inspired by sourdough technology has demonstrated a strong ability to reduce ANF, improve protein digestibility and nutrient bioavailability, and enhance the technological and sensory characteristics of legume flours and grains. In addition, fermentation contributes to improving food safety through the inhibition or transformation of spoilage microorganisms, pathogens, and toxic compounds. Beyond their direct consumption, fermented legumes are also key components of many traditional foods and can be successfully incorporated into innovative formulations of staple products, including baked goods and pasta, leading to foods with improved nutritional, functional, and shelf-life properties.\n\nID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, \u03b2-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1\u03b1 signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.\n\nID: 42429666\nTitle: Sialidase inhibitor modulates gut microbiota and enhances mucosal protection in the treatment of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is characterized by mucosal barrier erosion, a process exacerbated by bacterial sialidases. We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.\n\nID: 42421782\nTitle: Quantum dots in periodontology: emerging promise and translational challenges.\nAbstract: Periodontitis is a chronic inflammatory disease driven by microbial dysbiosis, resulting in irreversible destruction of the periodontal ligament and alveolar bone. Conventional therapies, including mechanical debridement and local drug delivery, frequently fail to achieve adequate outcomes in advanced disease due to poor biofilm penetration, limited site-specificity, and the inability to modulate the host immune microenvironment. Quantum Dots (QDs) are semiconductor nanocrystals measuring 1-10\u2005nm, which possess unique size-dependent photoluminescence, high photostability, broad excitation profiles, and versatile surface functionalization, properties that have not yet been systematically evaluated in the context of periodontology. This review evaluates QD applications across four domains: diagnostics and bioimaging, targeted therapeutics and local drug delivery, tissue engineering and regeneration, and dental implantology. In diagnostics, QDs enable ultrasensitive detection of salivary and crevicular inflammatory biomarkers, real-time pathogen imaging, and integration into wearable point-of-care platforms. Therapeutically, they facilitate photodynamic antimicrobial therapy, stimuli-responsive drug release, and improved bioavailability of agents such as curcumin and metformin. In regeneration, they promote osteogenic stem cell differentiation and immunomodulation of the local inflammatory microenvironment. On implant surfaces, they enhance antibacterial activity and osseointegration. Despite this breadth, clinical translation remains constrained by cytotoxicity of heavy-metal-based variants, physicochemical instability in the oral environment, and the absence of long-term in vivo data and harmonized regulatory pathways. QDs especially emerging carbon-based variants represent a scientifically promising nanoplatform for precision periodontal care, but bridging the gap from bench to chair will require standardized synthesis, rigorous safety profiling, and well-designed translational studies.\n\nID: 42415755\nTitle: Probiotic-fermented herbal residues in obesity management: a review.\nAbstract: The global prevalence of has reached epidemic proportions, largely driven by dietary shifts toward high-calorie, processed foods, and sedentary lifestyles. Obesity is a complex polygenic disorder characterized by excessive adipose tissue accumulation and adipocyte hypertrophy, leading to various metabolic dysfunctions. The gut microbiota plays a pivotal role in regulating host energy metabolism, and dysbiosis, an imbalance in its composition and function, is strongly linked to obesity development and progression, Traditional Chinese medicine (TCM) has long been utilized for weight management, yet \"efficiency limitations\" and \"resource waste\" remain significant concerns. This comprehensive review explores the emerging approach of using probiotic-fermented herbal residues for obesity management. We examine how fermentation technologies transform herbal byproducts into high-value anti-obesity preparations through biological processes that enhance bioactive compounds, improve bioavailability, and modulate the gut-liver axis. The integration of herbal medicine with modern biotechnology impossible represents a promising frontier in sustainable healthcare and precision medicine for metabolic disorders.\n\nID: 42403302\nTitle: Upper and lower airway crosstalk in acute exacerbations of COPD: a clinical and biological overview.\nAbstract: Acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) are acute worsening events characterized by increased dyspnea, cough, and sputum production. Although traditionally viewed as lower airway events, growing evidence suggests that AE-COPD may reflect broader pan-airway dysfunction involving both upper and lower respiratory compartments. This overview examines upper - lower airway crosstalk in AE-COPD across three domains: pan-airway inflammation, epithelial alarmin/cytokine networks, and the continuous airway microbiome. We discuss the coexistence of COPD with sinonasal inflammation, chronic rhinitis, and chronic rhinosinusitis, and their possible contribution to symptom burden, impaired quality of life, and exacerbation risk. We also review mechanisms linking upper and lower airways, including epithelial barrier dysfunction, impaired antiviral responses, innate immune activation, alarmin release, and microbiome-driven dysbiosis. Recognizing AE-COPD as a manifestation of pan-airway dysfunction may have relevant clinical implications. Systematic assessment of upper airway symptoms and comorbidities could improve phenotyping, risk stratification, and therapeutic targeting, particularly in frequent exacerbators. Future longitudinal and multi-omic studies are needed to validate upper airway biomarkers and determine whether targeted treatment of upper airway disease can modify COPD outcomes.\n\nID: 42386309\nTitle: Air pollution-induced airway epithelial barrier dysfunction in COPD: a narrative review of mechanisms and therapeutic implications.\nAbstract: Air pollution is particularly harmful to people with chronic obstructive pulmonary disease (COPD). Exposure to air pollution from sources such as biomass burning leads to a unique COPD phenotype. This phenotype mainly shows airway damage, with less emphysema than typical smoking-related phenotypes. Across various COPD phenotypes, airway epithelial barrier dysfunction is a basic pathological mechanism. This narrative review summarises the current available evidence on how different types of airborne pollutants, including particulate matter (PM), ozone (O3), diesel exhaust and microplastics, damage the airway epithelial barrier. The toxicity of fine PM with a diameter of \u22642.5 \u00b5m, one of its main constituents, largely depends on its chemical composition. Some metals or organic chemicals with redox properties can initiate oxidation reactions and induce pathologic responses. The main injury mechanisms are direct physical damage to apical junctional complexes, serious impairment of mucociliary clearance and induction of oxidative stress. Apart from these immediate harms, pollutants also create epigenetic modifications and disturbed epithelium-immune cell cross-talk, which breaks down the equilibrium of the airway epithelial barrier. These system-wide effects are exacerbated through the gut-lung axis, which aggravates local lung damage via microbiome dysregulation. We evaluate emerging therapeutic strategies that aim to restore barrier integrity, including antioxidants, natural compounds, inhibitors directing specific pathways (e.g. epidermal growth factor receptor (EGFR), NLR family pyrin domain containing 3 (NLRP3)) and microbiome modulation via probiotics. Protection and repair of the airway epithelial barrier offer a promising approach to reducing the onset and progression of pollution-related COPD in populations vulnerable to highly polluted environments.\n\nID: 42381725\nTitle: Precision prebiotics: Engineering food-derived polysaccharides to target specific SCFA-producing taxa for neuroprotection via the microbiota-gut-brain axis.\nAbstract: Neurodegenerative and neuropsychiatric disorders lack disease-modifying therapies. The microbiota-gut-brain (MGB) axis, particularly short-chain fatty acid (SCFA)-producing microbiota dysbiosis, has emerged as a conserved driver of neuroinjury pathogenesis. Natural food-derived polysaccharides have been explored as prebiotic substrates, but their clinical translation is hindered by poor target specificity, high interindividual heterogeneity, and low bioavailability. Engineered food-derived polysaccharides, as a next-generation precision prebiotic platform, enable rational tailoring of molecular fine structures via targeted physical, chemical, biological, and combinatorial modification technologies, aiming for strain-specific directional modulation of intestinal SCFA-producing microbiota and multi-pathway neuroprotection through the MGB axis. In this review, we systematically delineate the bidirectional regulatory mechanisms between SCFA-producing microbiota and neural homeostasis, dissect disease-specific pathological cascades driven by SCFA-producing microbiota dysbiosis, and discuss conflicting findings on the dual effects of SCFAs. We further propose a full-chain framework of the structure-activity relationship of engineered polysaccharides, dissecting core modification strategies, strain-specific targeting mechanisms, and a multi-dimensional efficacy evaluation system for these precision prebiotics. Additionally, we assess safety evaluation status, major global regulatory differences, and core clinical translation bottlenecks. Finally, we outline key unresolved challenges and propose a conceptual roadmap for AI-assisted rational design of precision prebiotics, personalized microbiota-adapted intervention strategies, and multicenter clinical translation directions. This review provides a mechanism-driven theoretical framework and practical guidance for developing engineered food-derived polysaccharides as precision nutrition interventions for neuroinjury-related disorders.\n\nID: 42364134\nTitle: Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways.\nAbstract: Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID-19, and asthma. The normal lung is not sterile, with a distinct microbial ecosystem that is spatially varied along the respiratory tract. The biogeography of the lung microbiome is balanced between microbial microaspiration from the oral-pharynx and clearance. The mouth is an important reservoir for respiratory pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, and Staphylococcus aureus, as well as oral microbes (Porphyromonas, Prevotella, Fusobacterium, etc.). Poor oral hygiene and periodontitis increase the bacterial load that can be aspirated, and the host produces pro-inflammatory components that enhance microbial virulence and compromize epithelial integrity. Both poor oral hygiene and periodontitis have been associated with pneumonia, particularly in hospitals and nursing home settings. Periodontitis may also facilitate viral pneumonia (including COVID-19) by altering receptor expression and immune function. Periodontitis correlates with COPD severity and exacerbation frequency through pathways involving matrix metalloproteinases and cytokines. Periodontitis also is associated with asthma and acute exacerbations. Inflammation shapes the lung microbiome by impacting microbial nutrient availability through vascular leakage, inducing changes to epithelial cells which facilitate bacterial adherence, and inducing the production of cytokines, leading to mucus overproduction, inhibition of phagocytosis, and enhancement of microbial pathogen virulence. Multiple biological pathways have been examined in\u00a0vitro that suggest how \"the oral-lung axis\" influences pneumonia, COPD, and asthma. Periodontal treatment and effective oral hygiene should be well integrated into medical care to prevent and manage respiratory diseases.\n\nID: 42354217\nTitle: The Potential for Bioactive Peptide Production in a Fermented Dairy Beverage Based on Chickpea Water Extract Using Proteolytic Lactic Acid Bacteria.\nAbstract: A chickpea-based milk beverage containing both plant and animal proteins represents an excellent substrate for the production of biologically active peptides through fermentation. Fermentation by lactic acid bacteria (LAB) increases its nutritional value compared to the unfermented beverage while improving the digestibility and bioavailability of essential nutrients via proteolytic enzyme activity. This study investigated the production of bioactive peptides in fermented chickpea water extract using ten bacterial strains isolated from plant and animal sources. The proteolytic activity of each strain was quantified using the trinitrobenzene sulfonic acid (TNBS) method, and the presence of proteolytic genes was confirmed via agarose gel electrophoresis. Peptides released during fermentation were identified through two-dimensional electrophoresis, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and tandem mass spectrometry. To predict the potential biological activities of the studied peptide sequences, a series of in silico analyses were performed using specialized bioinformatics tools. The identified peptides were predicted to exhibit antioxidant, antihypertensive, anticancer, antibacterial, antifungal, antituberculosis, and angiotensin-converting enzyme (ACE) inhibitory activities. Based on the results, L. fermentum SB-2 and L. sakei SD-8, were selected as promising candidates for bioactive peptide production in a chickpea water extract-based milk beverage and were subsequently applied in the beverage prototype.\n\nID: 42353283\nTitle: Molecular Mechanisms Underlying the Higher Prevalence of Anemia in Crohn's Disease Compared with Ulcerative Colitis: A Systematic Review.\nAbstract: Anemia represents one of the most frequent systemic complications of inflammatory bowel disease (IBD), with a consistently higher prevalence reported in patients with Crohn's disease (CD) compared with ulcerative colitis (UC). While chronic inflammation, impaired iron absorption, and intestinal blood loss are recognized contributors, microbiome-mediated mechanisms influencing host iron availability remain insufficiently explored. Emerging evidence indicates that CD-associated dysbiosis is characterized by an increased abundance of siderophore-producing bacteria, particularly members of the Enterobacteriaceae family. Because siderophores are high-affinity iron-chelating molecules capable of competing with host iron acquisition systems and partially escaping lipocalin-2-mediated sequestration, their expansion may contribute to reduced luminal iron bioavailability. In this systematic review, we analyzed comparative microbiome studies published between 2016 and 2026 that directly evaluated microbial differences between CD and UC. CD microbiota consistently demonstrated enrichment in siderophore-associated taxa relative to UC. Based on these findings, we propose that microbiome-driven iron competition may represent an additional mechanistic contributor to the increased prevalence and persistence of anemia observed in CD. Although direct in vivo quantification of siderophore activity in IBD remains limited, the convergence of ecological, functional, and strain-level microbiome evidence supports a biologically plausible interaction between microbial iron-scavenging strategies and host iron metabolism.\n\nID: 42352300\nTitle: The Gut-Lung Microbiome Crosstalk and Pulmonary Disease.\nAbstract: Both the gut and the lungs possess a microbiome, a community of commensal bacteria, archaea, fungi, and viruses that perform important housekeeping functions in those organs. The colonic microbiome primarily ferments indigestible dietary fibers into essential short-chain fatty acids, synthesizes essential vitamins, regulates the mucosal immune system, and forms a protective barrier against pathogenic colonization. The lung microbiome maintains respiratory health primarily by regulating mucosal immunity, providing a physical barrier against invading pathogens, and producing beneficial metabolites. Several colonic microbiota metabolites, including the short-chain fatty acids acetate, propionate, and butyrate, together with the tryptophan metabolites indole-3-acetate and indole-3-propionate, secondary bile acids, and the polyamines spermidine and putrescine, are transported to the lungs via the gut-lung axis. These colonic microbiota biomolecules suppress lung inflammation, strengthen immune homeostasis, and reduce the severity of respiratory diseases. In contrast, lung microorganisms and their metabolites can travel to the gut via the gut-lung axis, influencing intestinal immune responses and potentially leading to an imbalance of gut microorganisms or dysbiosis. This means that respiratory diseases may lead to digestive issues, intestinal inflammation and chronic diseases. Here, we have reviewed this crosstalk and its impact on the principal pulmonary diseases: asthma, chronic obstructive pulmonary disease, cystic fibrosis, bronchogenic carcinoma, COVID-19, interstitial lung diseases, pneumonia, and tuberculosis. It is concluded that the gut microbiome plays a significant part in lung health and disease. Diet, tobacco smoking and electronic cigarette vaping all impact both the gut and lung microbiomes.\n\nID: 42345642\nTitle: Characteristics of Respiratory Microbiome in COPD-A Literature Review.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a respiratory disease that progressively impairs airway function. Its aetiology and clinical presentation are very complex, resulting in an unpredictable course of the disease. The most important causes include smoking and environmental pollutants. However, upper airway microbiome dysbiosis has been linked with COPD severity. Through this review, we aim to compare the microbiome of the respiratory tract between its sites, and to see if there are any significant differences in the composition of the microbial flora of patients with COPD when compared to healthy individuals. While preparing this review, the PubMed database was searched using keywords such as bacteriome, COPD, exacerbation, and microbiome. Analysis of the airway microbiome shows that the three most abundant phyla are Firmicutes, Proteobacteria, and Bacteroidetes. The severity of the disease and the selected therapeutic methods influence the ratio of Proteobacteria and Firmicutes. It has been observed that a decrease in microbial diversity resulted in lower values of FEV1 in patients and could be related with COPD's progress and exacerbation events. While exacerbation cases need quick treatment, COPD's complex background makes it difficult to find a singular, microbial cause.\n\nID: 42345600\nTitle: Protective and Detoxifying Effects of Myrtus communis Essential Oil Against Bisphenol A-Induced Metabolic Disturbances in Wistar Rats.\nAbstract: Bisphenol A (BPA) is an endocrine disruptor widely used in industrial and consumer products. Its release into the environment raises major health concerns, particularly regarding metabolic disorders. After exposure, BPA leads to the accumulation of free BPA and its main metabolites, including bisphenol A-glucuronide (BPA-G), bisphenol A-disulfate (BPA-DS), and its chlorinated derivative, chlorinated bisphenol A-diglucuronide (BPA-DC). This study is aimed at evaluating the detoxifying effect of essential oil of Myrtus communis (EOMC) at 50, 100, and 200\u2009mg/kg, and vitamin E (100\u2009mg/kg), in male Wistar rats exposed to BPA (100\u2009mg/kg). Results showed a significant decrease in serum levels of BPA and its metabolites, along with increased urinary excretion, indicating enhanced biotransformation and elimination. BPA exposure also elevated fecal short-chain fatty acids (SCFAs) acetate, propionate, and butyrate, suggesting microbial dysbiosis and altered fermentation. EOMC and vitamin E treatments normalized SCFA profiles, demonstrating a modulatory effect on gut microbiota. The detection of \u03b1-pinene and 1,8-cineole in serum confirmed systemic bioavailability of EOMC and its role in detoxification. Overall, these findings highlight the protective effect of EOMC and vitamin E against BPA bioaccumulation and support their potential as natural detoxifying agents.\n\nID: 42340489\nTitle: Targeting microbiota-gut-brain axis with phytochemicals: a mechanistic roadmap for dementia.\nAbstract: Dementia is a growing global health concern, with limited therapeutic options. Treating dementia is a crucial but often overlooked part of neurological care for the elderly. The gut microbiota plays an essential role in the bidirectional interaction between the gut and the brain. Growing evidence suggests that gut microbes, which can influence neural development, modulate neurotransmission, and affect behaviour, may contribute to the development and pathophysiology of various neurodevelopmental, neuropsychiatric, and neurological disorders like dementia. This underscores the need for new interventions targeting the gut-brain axis(GBA). This review highlights the role and application of phytochemicals in treating dementia by modifying the GBA. We outline the harmful relationship between dementia and microbial dysbiosis, focusing on abnormal tryptophan- kynurenine metabolism, impaired SCFA synthesis, disruption of the BBB, and altered microglial activation states. Nevertheless, the potential of different phytochemicals, such as flavonoids, alkaloids, terpenoids, and polyphenols, to enhance neuroprotective metabolite production, restore microbial balance, regulate inflammatory signalling (e.g., NF- \u03bab, Nrf 2, MAPK, and TLR 4), and improve synaptic plasticity via pathways like BDNF-CREB, is under investigation. Key bioactive compounds like berberine, resveratrol, and curcumin are being tested for their efficacy concerning molecular targets and outcomes in both preclinical and clinical models of cognitive decline. In addition to specific phytochemicals, probiotic and prebiotic synergistic approaches may enhance gut homeostasis and cognitive resilience, opening avenues for functional food- based treatments. Although promising, challenges to clinical application remain, such as low bioavailability, standardisation issues, and interindividual microbiome variability. This review emphasises prospects for precision nutrition and microbiome- targeted therapies in dementia, discusses translational barriers, and summarises recent data on phytochemical modulation of the GBA in dementia.\n\nID: 42337354\nTitle: Fermented food microbiome: influence on oral and gut microbiota, and human health.\nAbstract: The fermented food microbiome comprises live microorganisms, their genetic elements and their metabolites, and represents an established dietary approach for modulating host-microbiome interactions through the consumption of fermented foods. Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease.\n\nID: 42324603\nTitle: Cross-kingdom microbiome interactions along the gut-lung axis: immune-microecological coordination, shared mechanisms, and disease-context dependence in respiratory disorders.\nAbstract: Cross-kingdom dysbiosis of the gut microbiome along the gut-lung axis has emerged as a key driver of chronic and acute respiratory diseases. Beyond bacteria, the intestinal mycobiome and virome, including bacteriophages, shape mucosal immunity and metabolism through partially overlapping but non-redundant pathways. In this Review, we synthesize rapidly expanding evidence that fungi, bacteria, and phages in the gut form an integrated network that may influence susceptibility, inflammatory tone, and therapeutic responsiveness across asthma, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and lung cancer via the gut-lung axis. We first summarize how cross-kingdom communities in the intestine are organized and interact, highlighting a tripartite framework centered on pathogen-associated molecular pattern-pattern recognition receptor (PAMP-PRR) circuits, the short-chain fatty acid (SCFA)-regulatory T-cell axis, and tryptophan-indole-aryl hydrocarbon receptor (AHR) signaling. We then compare how these shared axes are differentially perturbed across asthma, COPD, ARDS, and lung cancer, using these disorders as representative but non-sequential disease contexts along a conceptual gradient of immune-microecological disruption. Finally, we discuss how dietary modulation, pre-/pro-/postbiotics, mycobiome- and virome-targeted strategies, and phage-based approaches could be rationally combined to restore gut-derived immunometabolic circuits and improve respiratory outcomes. By integrating cross-kingdom ecology with mucosal immunology, this Review provides an integrative interpretive framework suggesting that gut microbiome-targeted strategies may help refine prevention, stratification, and adjunctive treatment approaches in selected respiratory disease contexts.\n\nID: 42317760\nTitle: Global research status and development trends of chronic obstructive pulmonary disease and gut microbiota: a comprehensive analysis based on bibliometrics and knowledge visualization.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by airflow obstruction due to chronic bronchitis and/or emphysema, which can further progress to cor pulmonale and respiratory failure. In recent years, the association between gut microbiota and COPD has attracted extensive attention from researchers. This study aimed to explore the current research hotspots, knowledge gaps, and future research trends in the field of gut microbiota and COPD. A comprehensive search of literature related to gut microbiota and COPD published between 2009 and 2025 was conducted using the Web of Science and Scopus databases. Bibliometric analyses were performed using VOSviewer, CiteSpace, and R software. The number of publications in this field showed a significant growth trend from 2009 to 2025, with the highest number of publications recorded in 2024. China and the United States were the leading contributing countries, and institutions such as the University of Technology Sydney made important contributions. The International Journal of Chronic Obstructive Pulmonary Disease served as the core publication platform in this field, and Hansbro, Philip M. was a key contributor. Research in this field involved keywords including gut-lung axis, inflammation, probiotics, bacteria, and short chain fatty acid, which revealed the core themes and trends of studies on gut microbiota and COPD. To our knowledge, this study presents the first quantitative bibliometric analysis of the field of gut microbiota and COPD. The core research hotspots identified include the characteristics of gut microbiota alterations in COPD patients, as well as the reciprocal interactions and underlying mechanisms between COPD and gut microbiota; microbiota intervention strategies have also emerged as an emerging research direction. Investigating immune regulation mediated by gut microbial metabolites has become an important trend in this field. This study provides a comprehensive analysis of the current research status and key hotspots in the field of gut microbiota and COPD, offering important references and insights for subsequent studies in related fields.\n\nID: 42295683\nTitle: Cucurbitacin derivatives (B, IIa, IIb, and E): modulating gut dysbiosis and inflammatory pathways for multi-target therapy of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is a colon-associated inflammatory bowel disease (IBD) that extends from rectum to complete colon characterized by ulceration, rectal bleeding, bloody diarrhoea, and abdominal pain, epithelial barrier disruption, gut dysbiosis, immune dysregulation and recurrent mucosal inflammation. Today, several clinical medications such as corticosteroids, aminoslicylates and immuno-modulators are available, but each one of them have their own side effects. Therefore, to overcome these limitations, we are moving toward herbal drug therapies. This review presents the emerging role of Cucurbitacin (Cu), a highly oxygenated tetracyclic triterpenoid compound found in a variety of Cucurbitaceae plants and known for its anti-inflammatory response. Unlike previous reviews which just focuses on single derivatives or isolated mechanisms, this review focuses on multi-target analysis of Cucurbitacin (Cu) derivatives- CuB, CuE, CuIIa, and CuIIb, their biosynthesis, structure-activity relationships (SAR), inflammatory pathway modulation, gut microbiota regulation, extracellular vesicle-associated microRNAs, and differentially expressed genes (DEGs). The preclinical evidences shows that these derivatives of Cu have capability to treat UC, by inhibiting the Inflammatory pathways such as NLRP3 inflammasome, NF-\u03baB, JAK2/STAT3, MAPK and EGFR, which results in decreasing the level of Inflammatory cytokines such as IL-6, IL-1\u03b2 and TNF-\u03b1. They also upregulates the SCFAs producing beneficial bacteria and downregulates the harmful bacteria, thereby restoring epithelial integrity. Notably, Cu \u2161a is associated with alteration in composition of protein and microRNA in extracellular vesicles. All these factors help in the treatment of UC. Although preclinical findings are encouraging, the current evidence is largely restricted to DSS induced animal models and the clinical validation in human is still lacking. Various challenges related to narrow therapeutic windows, poor bioavailability, and toxicity require resolution before clinical translation. This review find these translational gaps and proposes targeted research directions including nanoformulation strategies, pharmacokinetic profiling, and early-phase clinical evaluation.\n\nID: 42293193\nTitle: Molecular mechanisms and structure-activity relationships of natural polysaccharides in ameliorating type 2 diabetes mellitus: a comprehensive review.\nAbstract: Type 2 diabetes mellitus (T2DM) is a global metabolic pandemic affecting hundreds of millions of people, with current pharmacological therapies limited by adverse effects, long-term tolerability issues, and cost barriers. Natural polysaccharides-high-molecular-weight carbohydrate polymers derived from plants, fungi, marine organisms, and animal sources-have emerged as a promising class of multi-target bioactive agents for T2DM management. This comprehensive review first outlines the key pathophysiological mechanisms of T2DM, encompassing insulin resistance, pancreatic \u03b2-cell dysfunction, chronic inflammation, oxidative stress, and gut microbiota dysbiosis. We then systematically review the natural sources and structural classification of polysaccharides, alongside their extraction and purification methods. The core of this review examines the molecular mechanisms by which natural polysaccharides ameliorate T2DM: (1) enhancing insulin sensitivity and glucose metabolism via the PI3K/Akt and AMPK signaling pathways; (2) protecting pancreatic \u03b2-cells from apoptosis and promoting insulin secretion; (3) suppressing chronic inflammation through NF-\u03baB and NLRP3 pathway inhibition; (4) attenuating oxidative stress via Nrf2/HO-1 pathway activation; and (5) restoring gut microbiota homeostasis, reinforcing intestinal barrier integrity, and elevating short-chain fatty acids production. Structure-activity relationship analyses indicate that hypoglycemic efficacy is tightly correlated with molecular weight, monosaccharide composition, glycosidic linkage types, degree of branching, three-dimensional conformation, and chemical derivatization. Finally, challenges surrounding clinical translation, standardization, and bioavailability are discussed, along with future research directions. This review provides a theoretical framework for the application of natural polysaccharides as functional foods, nutraceuticals, or lead compounds in T2DM prevention and treatment.\n\nID: 42292489\nTitle: Dual role of IL-17A in COPD: amplifier of inflammatory cascades and mediator of airway remodeling and alveolar destruction.\nAbstract: Corticosteroid resistance remains a central challenge in managing chronic obstructive pulmonary disease (COPD). This refractory phenotype is primarily driven by persistent, neutrophil-dominated airway inflammation. Interleukin-17A (IL-17A) bridges innate and adaptive immunity and helps sustain this refractory inflammation, although it operates within a redundant cytokine network and its pathogenic contribution is clearest in a defined molecular subset of patients. Following an overview of upstream drivers including lung-gut microbiome dysbiosis and Th17/Treg immune imbalance, the downstream effector network of IL-17A is analyzed. In sustaining inflammation, IL-17A stabilizes pro-inflammatory transcripts via ACT1-mediated post-transcriptional regulation and produces a self-amplifying positive feedback loop with neutrophil extracellular traps (NETs). In tissue remodeling, IL-17A induces alveolar epithelial ferroptosis via the ACT1-TRAF6-p38 MAPK cascade to drive emphysema. It also mediates irreversible structural alterations in the airway and alveolar parenchyma by inhibiting fibroblast autophagy through the PI3K/AKT/mTOR pathway and inducing epithelial mucus hypersecretion. Given the lack of significant clinical benefit from early non-selective IL-17A blockade in unselected populations, precision intervention strategies guided by clinical endotypes are evaluated. Optimizing next-generation targeted therapies in COPD necessitates biomarker-driven patient stratification, coupled with upstream signal interception and the restoration of systemic immune homeostasis. Together, these strategies support a shift from symptomatic management toward endotype-specific disease modification.\n\nID: 42291325\nTitle: Profiling of human lung and gut microbiomes in different conditions of chronic obstructive pulmonary disease using ontology-based evidence synthesis and reasoning.\nAbstract: Chronic Obstructive Pulmonary Disease (COPD) remains one of the leading global causes of morbidity and mortality, with increasing evidence highlighting microbial dysbiosis as a key factor in disease progression and exacerbation. To resolve the inherent heterogeneity in COPD microbiome research, we developed a standardized pipeline termed as Ontology-based Evidence Synthesis and Reasoning (O-ESR), utilizing the Ontology of Host-Microbiome Interactions (OHMI) framework. Our analysis included over 30 studies and identified more than 100 significantly altered bacterial taxa in the human airway and gut microbiomes of human COPD patients across three clinical conditions: COPD versus healthy controls, exacerbation versus stable states, and severe versus moderate diseases. Profiling across taxonomic levels revealed a marked airway expansion of pathogenic genera, including Haemophilus, Moraxella, Pseudomonas, and Burkholderia. Species-level analysis confirmed the specific enrichment of Haemophilus influenzae and Pseudomonas aeruginosa, supporting their roles in airway inflammation and exacerbation susceptibility. In contrast, the gut microbiome of COPD patients exhibited a decrease of beneficial anaerobes involved in short-chain fatty acid (SCFA) production, including Bifidobacterium bifidum, Faecalibacterium prausnitzii, and members of Lachnospiraceae and Ruminococcaceae. Notably, ontology-based reasoning identified a shared depletion of commensal genera such as Prevotella and Veillonella across both anatomical sites and all three clinical conditions, indicating a systemic and progressive loss of microbial diversity. This integrated analysis reveals a COPD-associated microbial landscape characterized by airway Proteobacteria expansion and gut SCFA-producer depletion, suggesting coordinated epithelial dysfunction, immune dysregulation, and gut-lung axis involvement. These findings demonstrate the power of ontological reasoning in decoding complex host-microbiome interactions, providing a robust foundation for microbiome-informed stratification and targeted interventions in COPD management.\n\nID: 42542576\nTitle: The potential role of the lung-brain axis in the pathophysiology of epilepsy: A hypothesis-driven perspective.\nAbstract: The pathophysiology of epilepsy remains poorly understood. One of the less explored areas is the role of the lung-brain axis, a sophisticated and intricate bidirectional connection between these two vital organs. Inhaled air pollutants can disrupt lung microbiome homeostasis. This disruption, analogous to gut dysbiosis implicated in neurological conditions, may contribute to epilepsy pathogenesis. Here, we review the existing evidence and theoretical foundations supporting the hypothesis that dysbiosis within the lung microbiota may play a role in the pathophysiology of epilepsy. This includes the links between environmental factors (particularly air pollution) and epilepsy susceptibility; the associations between lung-intrinsic microbiota dysregulation and neurological dysfunction; and the underlying molecular, immunological, and neural mechanisms that enable the lung-brain axis to modulate epileptogenesis. Furthermore, we outline the possible potential pathogenic mechanisms of epilepsy from the perspective of the microbiota-lung-brain axis, offer fresh perspectives on the pathophysiology of epilepsy, and explore potential new research directions related to the lung-brain axis and epilepsy. We propose that a deeper understanding of the function of the lung-brain axis will provide new insights into the etiology, diagnosis, prognosis, and treatment of epilepsy.\n\nID: 42520861\nTitle: Dietary L-Malic Acid Supplementation during Early Pregnancy Improves Reproductive Performance through Modulation of Antioxidant Capacity and the Gut Microbiota-Metabolite Axis in Sows.\nAbstract: Embryo loss during early pregnancy is a major constraint on mammalian reproductive efficiency. We previously revealed that dietary L-malic acid (L-MA) supplementation benefits maternal health in sows during late pregnancy. However, the effect of L-MA on sows during early pregnancy is largely unexplored. In the present study, in vitro assays confirmed that L-MA directly promoted the adhesion of embryonic trophoblast (JAR) cells to endometrial epithelial (Ishikawa) cells, and alleviated H\u2082O\u2082-induced reactive oxygen species (ROS) accumulation in the endometrial cells. In vivo, L-MA supply during early pregnancy optimized the physiological environment in sows, thereby improving pregnancy outcomes, without altering circulating estradiol or progesterone levels on GD 28. L-MA significantly enhanced maternal antioxidant capacity and alleviated inflammatory responses. Metabolomics analysis showed that L-MA reshaped the maternal metabolic profile, modulated amino acid, lipid and nucleotide metabolism, and activated the NOD-like receptor signaling pathway and the cGMP-PKG signaling pathway. L-MA enriched beneficial bacteria, including short-chain fatty acid (SCFA)-producing, anti-inflammatory, and antioxidant taxa, while repressing inflammation-associated bacteria, and these specific taxa were significantly correlated with differential metabolites, antioxidant/anti-inflammatory markers, and reproductive outcomes. Overall, our data revealed that dietary L-MA supplementation during early pregnancy enhanced reproductive performance in sows. These benefits might be associated with shifts in the maternal gut microbiota-metabolite axis and enhanced antioxidant and anti-inflammatory capacities. Therefore, L-MA supplementation may be a potential strategy for ameliorating embryo loss and improving reproductive performance in mammals.\n\nID: 42519711\nTitle: Effects of Dietary Fish Meal Replacement With Yellow Mealworm (Tenebrio molitor) Meal on Growth, Intestinal Microbiota, Hepatopancreas Metabolites, and Immune Defense Against DIV1 in Giant Freshwater Prawn (Macrobrachium rosenbergii).\nAbstract: The yellow mealworm (Tenebrio molitor) stands out among insect protein sources for its ability to convert low-value agricultural by-products into valuable nutrients. This study evaluated the effects of replacing fish meal with yellow mealworm meal on growth performance, nutritional composition, intestinal microbiota, hepatopancreas metabolites, and immune defense against decapod iridescent virus 1 (DIV1) in giant freshwater prawn. Five isonitrogenous and isolipidic diets were formulated with yellow mealworm meal replacing fish meal at 0% (FM30), 10% (FM27), 20% (FM24), 40% (FM18), and 60% (FM12). A total of 750 prawns were randomly distributed into 15 tanks (three replicates per diet, 50 prawns per replicate) and cultured for 56 days, followed by a DIV1 challenge test. Results showed that Replacement of up to 60% of fish meal did not adversely affect growth performance, feed utilization, or the crude protein, crude lipid, and amino acid profiles in muscle. Muscle monounsaturated fatty acids (MUFAs) increased linearly with mealworm inclusion (p < 0.05). The FM12 group exhibited elevated arachidonic acid (ARA) and n-6 PUFA levels and reduced docosahexaenoic acid (DHA; p < 0.05), while the n-3/n-6 ratio remained unchanged. Gut microbiota composition shifted favorably, with increased abundance of Firmicutes and beneficial Lactococcus in the FM12 and FM18 groups (p < 0.05). Metabolic adaptation in the hepatopancreas involved glycerophospholipid metabolism, nucleotide metabolism, and pyruvate metabolism pathways. Following DIV1 challenge, the FM12 group showed significantly higher survival, increased plasma glutathione peroxidase (GPX) activity, decreased malondialdehyde (MDA) levels, and reduced hepatopancreatic apoptosis (p < 0.05). Immune-related upregulation of hpo, warts, mats, and ifn-\u03b1, alongside downregulation of caspase-3, was also observed (p < 0.05). In conclusion, replacing 60% of dietary fish meal with yellow mealworm meal is a nutritionally safe and beneficial strategy for giant freshwater prawn, effectively maintaining growth performance and muscle composition, modulating gut microbiota, and enhancing immune defense against DIV1.\n\nID: 42514673\nTitle: Conjoint Analysis of Sheep Microbiome, Metabolome, and Transcriptome Revealed the Effect Mechanisms of Feeding with Broccoli Extract.\nAbstract: Alterations in microbiota, transcript and metabolites are critical to intestinal homeostasis and host health. This study used a combination of 16s rRNA, transcriptome sequencing and liquid chromatography-mass spectrometry to investigate intestinal microbiota, genes and metabolic profiles in the ileum of Hu sheep fed broccoli extract. Here, we randomly allocated 14 Hu sheep to two diets: a basal diet without any supplementation (NC) and a basal diet supplemented with 200 mg/kg broccoli tail (BT). After 60 days of treatment, blood and jejunal samples were collected for serum biochemical indicators and multi-omics analysis. In this study, the extract of broccoli tails had a significant effect on the serum biochemical indicators, including white blood cells, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin concentration, mean platelet volume, triglycerides and total protein in Hu sheep (p < 0.05). Transcriptomic analysis showed that the 672 differentially expressed genes between the NC and BT groups were primarily enriched in linoleic acid metabolism, steroid hormone biosynthesis, and cholesterol metabolism. Metabolomics analysis using Kyoto Encyclopedia of Genes and Genomes enrichment showed that the 41 differentially abundant metabolites were mainly enriched in bile secretion, vitamin B6 metabolism, and the mTOR signaling pathway. 16S rRNA sequencing results indicated that the extract of broccoli tails increased the relative abundance of Peptostreptococcaceae and decreased the relative abundance of Lachnospiraceae, Lachnospirales, and Bacteroidaceae. Integrated transcriptome, metabolome, and microbiome analysis showed that the gut microbiota and host transcriptomic changes may participate in systemic metabolic regulation by modulating amino acid metabolism, lipid signal transduction, nucleotide metabolism, and vitamin B6-related metabolic pathways. These findings demonstrate that the extract of broccoli tails modulates intestinal gene expression, systemic metabolism, and gut microbial ecology in Hu sheep, providing new insights into the utilization of agricultural byproducts as a functional feed supplement for ruminants.\n\nID: 42511301\nTitle: Enhancing Nutritional and Health Benefits of Wheat Bran Through Bifunctional LAB Screening and BCAA-Enriched Fermentation.\nAbstract: Lactic acid bacteria (LAB)-mediated fermentation has been widely explored as a strategy to enhance the nutritional functionality of cereal processing by-products. In this study, 50 LAB strains previously isolated from Korean traditional fermented foods and obtained from the National Agrobiodiversity Center (KACC, Jeonju-si, Republic of Korea) were systematically screened for bifunctional carbohydrate and protein degradation capacities, and their potential to improve the nutritional functionality of wheat bran was evaluated. Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations.\n\nID: 42442577\nTitle: Torreya grandis polysaccharide alleviates acute lung injury via the lung-gut axis: Gut microbiota and immune regulation mechanisms.\nAbstract: Acute lung injury (ALI) is a severe condition with high morbidity and mortality, for which effective treatments remain limited. Polysaccharides have been shown to enhance gut microbiota diversity, regulate microbial composition, and promote beneficial bacteria, thereby exerting immunomodulatory effects. Torreya grandis Fort. et Lindl polysaccharide (TGP) is a key bioactive component derived from Torreya grandis (TG). Understanding how gut microbiota dysbiosis in ALI influences pulmonary inflammation through the lung-gut axis, and whether TGP can ameliorate ALI pathology by modulating this axis, is of great interest. However, the specific mechanisms of TGP remain unclear. This study aimed to explore the therapeutic effects of TGP on ALI in mice via the lung-gut axis and its underlying mechanisms. The results showed that TGP alleviated both intestinal and lung injury, significantly improving intestinal barrier function by upregulating the expression of tight junction proteins, secretory immunoglobulin A (sIgA), and mucin 2 (MUC-2). TGP also modulated gut microbial communities in a favorable manner, fostering the proliferation of beneficial bacteria and elevating short-chain fatty acids (SCFAs) levels. Notably, in contrast to most polysaccharide studies that have primarily focused on acetate and butyrate, TGP markedly restored the levels of caproic acid and enriched SCFA-producing genera such as Norank_f_Muribaculaceae. These changes ameliorated immunothrombosis and restored immune cell subsets. Furthermore, TGP reduced the protein expression associated with the Toll-like receptor 4/nuclear factor-kappa B (TLR4/NF-\u03baB) signaling cascade. Collectively, these findings suggest that TGP may mitigate the inflammatory response in ALI mice by modulating the lung-gut axis, with its potential roles in caproic acid regulation and immunothrombosis amelioration offering new insights into lung-gut axis-targeted therapeutic strategies for ALI.\n\nID: 42434393\nTitle: Metabolomic and Metagenomic Correlation Reveals the Network Regulatory Mechanism of Cecal Microbiota Structural Changes Induced by Eimeria tenella.\nAbstract: Eimeria tenella poses a significant threat to the poultry industry, and understanding the correlation between metabolic changes in cecal tissues and microbial community alterations is crucial for studying parasite-host interactions. To investigate the associations among dominant bacterial populations, key functional genes, and altered metabolites in cecal tissues and contents during E. tenella infection. Metagenomic analysis was first performed on cecal contents to identify the dominant bacterial communities, followed by metabolomic analysis of cecal tissues and contents. Correlation analysis was then conducted to evaluate the relationships among microbial communities, functional genes, and differential metabolites. Correlation analysis showed that increased potentially pathogenic genera were generally positively associated with upregulated metabolites and negatively associated with downregulated metabolites, whereas reduced commensal genera showed the opposite trend. Shared KEGG pathways co-enriched by differential metabolites and microbial functional genes were identified, mainly involving amino acid metabolism, transport systems, membrane-associated metabolism, and nucleotide metabolism. The metabolites linked to dominant bacterial communities were primarily enriched in pathways such as amino sugar metabolism, sialic acid metabolism, and glycerophospholipid metabolism. These findings reflected complex metabolic reprogramming and interactions between the host and pathogen, especially in cecal tissue repair, immune regulation, and metabolic competition with the pathogen. This study provided valuable insights into parasite-host interactions and laid a foundation for understanding the role of bacterial community-associated metabolites in cecal coccidiosis.\n\nID: 42387159\nTitle: Phytochemical Engineering of Alternative Plant Proteins for Enhanced Nutrition and Digestibility.\nAbstract: Global protein security is increasingly challenged by the growing demand for sustainable alternatives to animal-derived proteins. Although plant proteins are central to this transition, they remain limited by imbalanced amino acid profiles, reduced digestibility, and inferior techno-functional properties, restricting their nutritional equivalence. Recent studies have explored processing strategies to address these limitations; however, these approaches are often evaluated independently, with limited integration of structural mechanisms and phytochemical-protein interactions. This review presents a comparative and mechanistic synthesis based on cross-study evaluation, integrating protein structure, processing-induced modifications, and phytochemical-assisted interactions. Processing strategies including extrusion, fermentation, enzymatic hydrolysis, and pH shifting primarily enhance protein accessibility and reduce antinutritional constraints. In contrast, phytochemicals modulate protein conformation and interfacial behavior through both non-covalent and covalent interactions. Evidence across studies indicates that these effects are strongly concentration-dependent: moderate phytochemical interactions promote partial unfolding and improved functionality, whereas excessive interactions induce aggregation and reduce digestibility. Notably, the combined application of bioprocessing and phytochemical strategies yields greater improvements in solubility, emulsification, and bioavailability than individual approaches, although variability in protein source and processing conditions remains a key limitation. Overall, this review establishes a mechanistic framework linking protein structure, processing dynamics, and phytochemical interactions, highlighting concentration-dependent effects and synergistic strategies for improving plant protein functionality, while identifying variability and optimization challenges for future applications.\n\nID: 42354404\nTitle: Deamidated Zein Peptide Nanoparticles for Enhanced Quercetin Delivery: Structural Analysis, Stability, and Antioxidant Properties.\nAbstract: To address the poor solubility, instability, and low oral bioavailability of quercetin (Q), Q-loaded nanoparticles (Q@DDZ) were fabricated using deamidated zein peptide (DDZ) via a pH-driven method. As a food-grade hydrophilic colloid, DDZ effectively improves the colloidal stability of the delivery system. Deamidation increased hydrophilic amino acids and surface negative charge. DDZ bound Q via static quenching with a higher binding constant (Ka = 2.25 \u00d7 103 L/mol) and more binding sites (n = 1.7561) than zein, along with stronger hydrogen bonding and hydrophobic interactions. Q@DDZ exhibited higher encapsulation efficiency (45.36-87.32%) and loading capacity (1.82-12.27%) than Q@zein, with a smaller particle size and better dispersibility. At 50.0 \u03bcg/mL Q, Q@DDZ showed 41.06% (DPPH) and 46.62% (ABTS) higher scavenging rates than free Q. It displayed excellent stability under acidic, high ionic strength, and thermal conditions (80 \u00b0C, 180 min). In simulated digestion, Q@DDZ delayed Q release in the oral and gastric phases and prolonged intestinal release, which indicated potentially improved bioavailability. This study provides mechanistic insights into deamidation-modified plant protein delivery systems for hydrophobic bioactives, offering new perspectives for the development of functional biopolymer gel materials.\n\nID: 42353998\nTitle: Gut Microbiome Responses to Nutritional and Lifestyle Interventions in Pediatric Obesity: A Systematic Review Toward Precision Nutrition.\nAbstract: Background: Childhood obesity is increasingly associated with gut microbiome dysbiosis. This systematic review (PROSPERO CRD420251131354) evaluates evidence from studies published between 2020 and 2026 assessing how nutritional and lifestyle interventions influence gut microbiota in children with obesity. Methods: A systematic search of PubMed, EMBASE and EBSCO identified 21 interventional studies involving children aged 5-18 years with obesity, with the last search conducted in April 2026. Interventions comprised prebiotics, probiotics, synbiotics, postbiotics, high-fiber diets, calorie-restricted dietary approaches, and lifestyle modifications such as physical activity. Microbiome outcomes were analyzed using 16S rRNA sequencing, quantitative real-time polymerase chain reaction (qPCR), or metagenomics. Risk of bias was evaluated using the RoB 2 and ROBINS-I (version 2) tools. Due to substantial heterogeneity in study design, participant characteristics, intervention types, and analytical methods, a meta-analysis was not feasible. Results: Across 21 studies, nutritional interventions included measurable but heterogeneous alterations in gut microbiome composition. Inulin supplementation was associated with a significant increase in alpha diversity and with higher relative abundances of Bifidobacterium, Blautia, Megasphaera, Subdoligranulum, and Eubacterium coprostanoligenes. Synbiotic supplementation increased Prevotella and Dialister and reduced the Firmicutes/Bacteroidetes ratio. High-fiber dietary interventions increased Faecalibacterium, Bifidobacterium, and Clostridium, while reducing Bacteroides, and were associated with shifts in metabolic pathways related to carbohydrate, lipid, and nucleotide metabolism. Calorie-restricted diets and combined diet-exercise interventions increased beneficial taxa such as Akkermansia muciniphila, improved microbial diversity, and correlated with favorable metabolic and anthropometric outcomes. Overall, nutritional and lifestyle interventions in pediatric obesity were associated with taxon-specific and context-dependent microbiome changes, rather than uniform restructuring. Conclusions: Nutritional interventions can modulate gut microbiota diversity, composition, and predicted function in pediatric obesity; however, the observed effects vary substantially across studies. The limited number of trials, small sample sizes, and methodological heterogeneity underscore the need for larger, standardized studies to better define clinical and therapeutic implications.\n\nID: 42346341\nTitle: Integrating Metabolomics and Gut Microbiota to Reveal the Therapeutic Effect of Lonicerae japonicae Flos Against Respiratory Syncytial Virus.\nAbstract: Objectives: This study aimed to investigate the therapeutic effects and potential mechanisms of Lonicerae japonicae Flos (Jinyinhua, JYH) against respiratory syncytial virus (RSV)-induced pneumonia by integrating lung tissue metabolomics with gut microbiota analysis. Methods: An RSV-infected mouse model was established through intranasal inoculation. Lung pathological changes, viral RNA levels, lung index, and inflammatory cytokine levels were evaluated. Untargeted metabolomics and 16S rRNA gene amplicon sequencing were performed to characterize JYH-mediated alterations in pulmonary metabolites and the gut microbiota. Spearman correlation analysis was conducted to assess associations between differentially abundant bacterial genera and significantly altered metabolites. Results: JYH alleviated RSV-induced pulmonary histopathological injury, reduced viral RNA levels, decreased lung index and interleukin-6 (IL-6) levels, and increased interferon-\u03b3 (IFN-\u03b3) levels. Metabolomic profiling identified 46 differential metabolites, among which 26 showed a reversal trend following JYH administration. These metabolites were mainly enriched in pathways associated with the synaptic vesicle cycle, lysosomal function, and Forkhead box O (FoxO) signaling. Gut microbiota analysis showed that JYH increased microbial richness and diversity, whereas KEGG-based functional prediction indicated that the differentially abundant taxa were primarily involved in amino acid, carbohydrate, and nucleotide metabolism. Moreover, correlation analysis revealed significant associations between key bacterial genera, including Gemella, Sutterella, and CC_115, and differential metabolites such as pyridoxamine, uridine monophosphate (UMP), and argininosuccinic acid. Conclusions: JYH may protect against RSV-induced pneumonia by restoring pulmonary metabolic homeostasis and modulating gut microbiota composition. These findings provide new insights into metabolite-microbiota interactions underlying the anti-RSV activity of JYH.\n\nID: 42328059\nTitle: Differential analysis of gut microbiota between captive and wild forest musk deer (Moschus berezovskii) based on 16S rRNA sequencing.\nAbstract: Forest musk deer (Moschus berezovskii) is a globally endangered species, and its conservation has long been a matter of concern. Wild populations are scarce, while artificially captive populations are also constrained by health issues such as digestive system diseases. To reveal the differences in gut microbiota between captive and wild forest musk deer from different geographical regions, fecal samples were collected from captive individuals in Nanyang, Henan (HN) and Gaoping, Shanxi (SX), as well as wild individuals in Baotianman, Henan (YS), with 5 samples per group. High-throughput 16S rRNA sequencing was employed to analyze the microbial community structure and function. The sequencing revealed Firmicutes, Bacteroidota, and Proteobacteria as the dominant phyla across all three groups, with Actinobacteriota exhibiting a significantly higher abundance in the YS wild group (11.13%) than in the HN (1.29%) captive and SX (6.12%) captive groups. There were no significant differences in \u03b1-diversity among the groups. However, \u03b2-diversity analysis (PCoA and NMDS) indicated a clear separation in microbial community structure between captive and wild groups, with some individuals in the SX captive group clustering with the wild group. LEfSe analysis identified 36 differential biomarkers: the YS wild group was enriched in genera including Bacillus, Arthrobacter, and Microbacterium, whereas the HN captive group was enriched in Bacteroides, Clostridium, and Eubacterium, while the SX captive group was enriched in Skermanella (genus) and Cytophagales (order). Functional prediction analysis revealed that the gut microbiota of the wild group was significantly enriched in the pathways of xenobiotics biodegradation and metabolism as well as lipid metabolism, whereas the captive groups showed higher activity in the translation and nucleotide metabolism pathways. This study reveals the impacts of rearing methods and geographical factors on the gut microbial community structure and function of forest musk deer. These findings can serve as a theoretical foundation for promoting healthy breeding of captive populations and as a reference for evaluating the health status of wild populations.\n\nID: 42327796\nTitle: Non-invasive detection of pediatric atopic dermatitis based on fecal microbiota and metabolite profiles: a diagnostic approach.\nAbstract: Atopic dermatitis (AD) is a common chronic skin inflammation, which affects 15-20% of children worldwide. Gut microbiota and its metabolites are crucial modulators of the \"gut-skin axis\" in atopic dermatogenesis. However, systematic investigations integrating microbiome and metabolome profiling in mild-to-moderate pediatric AD remain limited. To characterize gut microbiota and metabolic profiles in children with mild-to-moderate AD versus healthy controls, and to identify potential biomarkers and mechanistic pathways involved in disease pathogenesis. This single-center case-control study investigated 53 children diagnosed with AD and 16 healthy participants, and collected their fecal samples for microbial and metabonomic analysis. Mild-moderate pediatric AD patients exhibited significantly increased gut microbial richness and distinct \u03b2-diversity compared to controls (PERMANOVA, R\u00b2=0.025, P\u00a0=\u00a00.017). Bacteroidota was enriched while Actinomycetota was depleted in AD patients (P <\u00a00.05). At genus level, Parabacteroides and Klebsiella increased, whereas Bifidobacterium decreased in AD. Species-level analysis revealed enrichment of bacteroides_plebeius, bacteroides_thetaiotaomicron, bacteroides_xylanisolvens, and parabacteroides_merdae in AD. A combined biomarker panel (Bacteroidota, Parabacteroides, and four key species) demonstrated promising exploratory diagnostic potential (AUC\u00a0=\u00a00.941, accuracy 84.6%), although these results require external validation in larger independent cohorts. Spearman analysis showed correlations between gut microbiome and clinical severity indicators. Thermodesulfobacteriota, Actinomycetota, Bifidobacterium, and specific ruminococcus strains positively correlated with the severity of AD. Metabolomics identified 68 differentially accumulated metabolites, primarily involved in lipid metabolism and nucleotide metabolism. Bacteroides species showed significant positive correlations with isovaleric acid levels in microbiota-metabolite analyses. Mild-to-moderate pediatric AD is characterized by distinct gut microbiota dysbiosis and metabolic alterations involving lipid metabolism. Cross-sectionally identified microbial features show exploratory associations with AD status, but causal inference is not possible. These hypothesis-generating findings support further investigation of the gut-skin axis in AD development and provide a rationale for future interventional studies targeting the microbiome and metabolome.\n\nID: 42264765\nTitle: Synergistic toxicity of abamectin with nanoplastics in rainbow trout mediated by gut-liver axis disruption: Insights into oxidative stress, metabolic dysregulation, and microbiota change.\nAbstract: Abamectin (ABM), a widely used pesticide in aquaculture, may interact with pervasive environmental contaminants like nanoplastics (NPs), potentially altering its toxicity to non-target organisms. This study investigated the synergistic effects and underlying mechanisms of polystyrene NPs and ABM at environmentally relevant concentrations in juvenile rainbow trout (Oncorhynchus mykiss) during a 28-day exposure. Compared to ABM alone, co-exposure with NPs induced significantly greater synergistic toxicity. This was evidenced by exacerbated intestinal barrier dysfunction, including downregulation of tight junction proteins (Occludin, Claudin-23, ZO-1) and a shift in the gut microbiota characterized by the enrichment of potential pathogens, such as Neochlamydia. In the liver, the combined exposure markedly enhanced oxidative stress and inflammatory responses. Untargeted metabolomics further revealed that the co-exposure disturbed fundamental metabolic pathways more profoundly than either contaminant alone, particularly affecting amino acid, carbohydrate, and nucleotide metabolism. Critically, correlation analyses integrated gut microbiota dysbiosis with hepatic metabolic disorders, supporting a pivotal role for gut-liver axis disruption in the synergistic toxicity. Our findings demonstrate that NPs can act as an aggravating factor, significantly potentiating the physiological and toxicological impacts of ABM on fish via interconnected intestinal and hepatic pathways. This study provides crucial mechanistic insights for the risk assessment of pesticide interactions with emerging contaminants in aquatic environments.\n\nID: 42203119\nTitle: From multi-omics insights to single-strain proof: How traditional agricultural system enhances fish flavor via the microbiome-gut-muscle axis.\nAbstract: Intensive aquaculture has significantly boosted aquatic product yields, but it often compromises sensory quality and remains constrained by reliance on unsustainable fishmeal. The Mulberry-dyke and Fish-pond system, used in China for millennia, suggests a circular approach, yet the underlying mechanism remains poorly understood. In this study, silkworm excrement (SE) from traditional sericulture (TSE) and modern insect factories (ISE) was evaluated as a functional aquafeed. Body weight, gut histology, and immunohistochemistry were employed to assess host health. Gut microbiome, electronic tongue analysis, and muscle metabolomics were conducted to assess fish flavor and identify flavor-related microorganisms. A single-strain feeding experiment further validated the microbiome-gut-muscle axis using electronic tongue analysis, gut transcriptomics, and determination of free amino acids and nucleotides. SE supplementation maintained fish yield while improving intestinal structure. Compared with commercial feed (CF), both SE treatments increased gut microbial diversity and community stability, and more than half of the significantly different ASVs were shared between the TSE and ISE groups, mainly involving immune regulation, nutrient metabolism, and flavor formation. SE, particularly TSE, enhanced antioxidant capacity and reduced lipid peroxidation, possibly through microbial regulation of lysophosphatidylcholines. As consistently indicated by electronic tongue and muscle metabolomics analyses, SE significantly improved fish flavor, with increased umami and reduced bitterness. Network analysis and single-strain feeding further suggested that Methylorubrum populi, Gemmobacter aquatilis, and Rhodobacter sphaeroides contributed to flavor improvement by regulating host amino acid and nucleotide metabolism along the microbiome-gut-muscle axis. These findings highlight SE as a promising sustainable bioresource for aquaculture.\n\nID: 42203021\nTitle: Analyzing differences in gut microbiota in secondary failure of sulfonylureas through 16S rDNA sequencing and metabolomics.\nAbstract: Currently, sulfonylureas, a class of medications used in type 2 diabetes mellitus (T2DM) treatment, are widely applied, but the problem of secondary failure isn't fully understood. This study aims to explore the potential mechanisms of secondary failure of sulfonylureas (SFS) and to identify reliable predictive biomarkers. In this study, 16S rDNA sequencing technology and non-targeted metabolomics were used to analyze the differences in gut microbiota and metabolic products between the SFS and sulfonylurea effective (SE) groups. The results of 16S rDNA sequencing indicated that there are differences in composition between two groups. Seventeen different bacterial types were identified, including six types from SFS patients and eleven from SE. SFS might be linked to disturbances in energy metabolism, amino acid metabolism, nucleotide metabolism, and lipid metabolism within the gut microbiota. Metabolomics results showed 66 different metabolites between two groups (49 metabolites were upregulated, and 17 metabolites were downregulated). Correlation analysis between gut bacteria and fecal metabolites revealed that 4 types of gut bacteria were significantly linked to 5 types of metabolites. This study reveals distinct gut microbiota composition in patients with sulfonylurea secondary failure, helping us understand changes in gut metabolites and providing new biomarkers for personalized treatment.\n\nID: 42198987\nTitle: Myco-foods and the gut microbiome: impacts of mycelial extracts, biomass, and mold-fermented foods.\nAbstract: Edible filamentous fungi include mushrooms and molds, which are consumed as extracts, mycelial biomass, and fermented foods. These fungal foods are often high in protein and fiber and are generally regarded as nutritious. This narrative review examines current knowledge on how mycelia from molds, including edible strains of Aspergillus, Rhizopus, Neurospora, Fusarium, Mucor, and Paecilomyces, affect the gut microbiome. Allfour human trials on these foods (two extracts, one biomass, and one fermented food) reported a measurable effect on the gut microbiome. These studies, plus the additional eight animal and eight in vitro studies performed, frequently found increases in the proportions of intestinal Akkermansia, Bifidobacterium, and lactobacilli. Bacteroides, Roseburia, and Eubacterium, which are recognized for their roles in fiber metabolism, were also frequently enriched, and numerous studies reported increases in fecal short-chain fatty acids. Notably, effects on the gut microbiome may be fungal species and food format-dependent. Although \u03b2-glucans and chitin are likely key determinants of gut microbiome responses to dietary mycelium, future studies should investigate how these and other potentially bioactive components of mycelia and fungal metabolites are metabolized by intestinal microorganisms. Such studies will result in an improved understanding of how myco-foods could support human health.\n\nID: 42197548\nTitle: Effects of Dietary Salvia sclarea L. Extract Supplementation on the Gut Microbiota, and Serum Metabolome in Lambs.\nAbstract: Salvia sclarea L. extract contains various bioactive components such as flavonoids and fatty acids, exhibiting anti-inflammatory, antioxidant, and antibacterial properties. This study aimed to investigate the effects of Salvia sclarea L. extract on the gut microbiota and serum metabolome in lambs. Sixty 2-month-old Chinese Merino female lambs (body weight 20 \u00b1 2 kg) were randomly assigned to five groups. The control (CK) group received the basal diet only, while the treatment groups received the basal diet supplemented with 0.04 mL/kg (CL1), 0.08 mL/kg (CL2), 0.12 mL/kg (CL3), and 0.16 mL/kg (CL4) of Salvia sclarea L. extract, respectively. The results showed that Firmicutes, Bacteroidetes, Spirochaetes, and Proteobacteria were identified as the dominant phyla across all groups (>90%). Compared with the CK group, CL1 and CL2 groups significantly reduced the relative abundance of Tenericutes (decreased by 38.2% and 32.9%, respectively, p < 0.05); the relative abundance of Patescibacteria in the CL1 group was significantly lower (decreased by 55.2%, p < 0.05). At the genus level, Ruminococcaceae constituted a substantial proportion, including Ruminococcaceae UCG-005, UCG-010, UCG-014, and NK4A214 group. STAMP analysis revealed that Klebsiella was significantly enriched in CL2, CL3, and CL4 groups compared to the CK group (p < 0.05). Correlation analysis between microbiota and immune indices showed that Christensenellaceae R-7 group was significantly negatively correlated with TNF-\u03b1 (p < 0.05); Ruminococcaceae UCG-005 was significantly negatively correlated with IFN-\u03b3 (p < 0.05) and showed a negative correlation trend with immunoglobulins (IgA, IgG, IgM). Conversely, Ruminococcaceae UCG-014 was significantly positively correlated with IL-4 (p < 0.05) but showed a negative correlation trend with IgM. Untargeted metabolomics analysis identified 8, 18, 25, and 20 differential metabolites in CL1, CL2, CL3, and CL4 groups, respectively. Notably, 3-hydroxy-7-methoxyflavone and Gamma-Glu-Cys were significantly upregulated across all treatment groups. KEGG pathway enrichment analysis indicated that these differential metabolites were primarily involved in nucleotide metabolism, fatty acid biosynthesis, and oxidative stress-related pathways. Further Spearman correlation analysis revealed significant associations between gut microbiota and differential metabolites. Specifically, g_Klebsiella was significantly positively correlated with 3-Hydroxycapric acid and 3-hydroxy-7-methoxyflavone (p < 0.05). In conclusion, Salvia sclarea L. extract modulates host energy metabolism by regulating nucleotide metabolism and fatty acid biosynthesis, and enhances immune function by alleviating oxidative stress, through the remodeling of gut microbiota and serum metabolome.\n\nID: 42186554\nTitle: Yeast nucleotide enhances barrier function by regulating the intestinal microbiota and metabolic pathways of fish to alleviate virus-induced intestinal damage.\nAbstract: Yeast nucleotides are known to modulate host immunity and gut microbiota. In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

However, their effect on the gut microbiota remains incompletely understood, despite emerging evidence suggesting potential long-term alterations in microbial composition and reductions in beneficial taxa. In this study, Lactobacillus acidophilus, a well-known probiotic species, was used as a representative model organism to investigate the microbiological effects of PPIs. This specific bacterium is linked to immune modulation, vitamin metabolism, and the preservation of the epithelial barrier. The effects of PPIs on L. acidophilus at the structural and functional levels were elucidated by an integrated framework including subtractive genomics, molecular docking, molecular dynamics (MD) simulations, antimicrobial assays, and transcriptional analysis. Using a multi-criteria scoring system, essential, non-redundant, non-human homologous cytoplasmic proteins were ranked and mapped to important pathways such as ATP synthesis, peptidoglycan biosynthesis, amino-sugar metabolism, nucleotide metabolism, and protein maturation. Molecular docking suggested potential binding of pantoprazole and rabeprazole to targets such as MurA, MurB, MurE, GlmS, NadE, AtpD, Def, and PyrH proteins. MD simulation showed stable protein-PPI complexes with localized flexibility changes near catalytic domains while preserving the global fold. Consistent with in-silico expectations, both pantoprazole and rabeprazole exhibited dose-dependent growth inhibition of L. acidophilus, whereas qRT-PCR revealed transcriptional downregulation of genes involved in cell-wall production, NADH metabolism, and energy generation. Pantoprazole elicited the most uniform transcriptional suppression, whereas rabeprazole had stronger but more varied effects. The present findings provide preliminary insights into potential interactions between PPIs and probiotic bacteria at the molecular and cellular levels. However, the results reflect species-specific responses under in vitro conditions and should be interpreted cautiously, as transcriptional changes do not directly confirm functional inhibition and the concentrations tested may represent upper-range exposure scenarios. Further in vivo and multi-species studies are required to validate this observation and better understand their clinical implications for microbiome stability during PPI therapy.\n\nID: 42142727\nTitle: Gut microbiome and metabolic responses of adult zebrafish (Danio rerio) to the co-exposure of polyethylene microplastics and levofloxacin.\nAbstract: The co-occurrence of microplastics (MPs) and antibiotics in aquatic environments poses complex ecological risks. This study investigated the combined toxicity of polyethylene microplastics (PE MPs) and levofloxacin (LEV) in zebrafish using integrated untargeted metabolomics and gut microbiome profiling. Zebrafish were exposed to environmentally relevant concentrations of LEV (0.1\u00a0\u03bcg/L, 1\u00a0\u03bcg/L, 100\u00a0\u03bcg/L), PE (1\u00a0mg/L), and their combinations for 96\u00a0h. LEV exposure produced concentration-dependent metabolic toxicity, progressing from energy conservation at 0.1\u00a0\u03bcg/L to inflammatory activation at 1\u00a0\u03bcg/L, and ultimately to system-wide metabolic perturbation at 100\u00a0\u03bcg/L. PE independently disrupted oxidative stress and membrane integrity pathways. Co-exposure generated emergent interactive effects exceeding additive predictions, with PE\u00a0+\u00a0LEV 0.1\u00a0\u03bcg/L affecting 387 metabolites versus 245 for LEV alone. Crucially, co-exposure elicited synergistic toxicity with unique metabolic fingerprints-including neuroendocrine activation (dynorphin B) and mTOR signaling modulation-that were absent in individual treatments. Conversely, microbiome analysis revealed an antagonistic interaction; while LEV alone caused significant dysbiosis and enrichment of resistant taxa, co-exposure stabilized microbial diversity and composition, likely due to LEV adsorption onto PE particles reducing luminal bioavailability. These findings highlight a \"microbiome-host interaction paradox\": PE mitigates antibiotic-induced gut dysbiosis yet exacerbates host systemic toxicity through mechanisms of epithelial barrier disruption and pharmacokinetic modulation. This study demonstrates that microbiome stability does not reliably predict host physiological health under multi-stressor conditions, underscores the importance of integrative, multi-omics approaches to assess the emergent risks of complex environmental mixtures.\n\nID: 42130486\nTitle: Fermented Dairy Products as Modulators of the Gut Microbiome: Greek Yogurt as a Model System.\nAbstract: Greek yogurt, characterized by its thick texture and higher protein content, contains reduced lactose levels while still preserving large colonies of active bacteria when compared to conventional (or \"traditional\") yogurt. The starter cultures listed on its label do more than just ferment milk; they actively reshape the gut microbiome and adjust host physiology. This review examines currently available observations about distinct bacterial types within this product, especially regarding its effects on intestinal balance. The ability to produce short-chain fatty acids is a property linked to these strains, along with the potential to stabilize gut lining function, adjust immunity patterns, aid blood sugar regulation, and even offer possible cardiovascular benefits. Greek yogurt's properties and potential differ from other fermented food items. Findings from experimental and clinical research suggest the lactic acid and Bifidobacterium species found in Greek yogurt contribute to increased microbiota variety, encourage growth of butyrate-producing bacteria, and strengthen the intestinal lining. Inflammation levels are reduced by these microbes, leading to greater lactose tolerance, smoother digestion, and balanced metabolic activity. Still, much of the available data is limited because most studies do not distinguish Greek yogurt from conventional yogurt in their analyses, even though differences exist in live cultures, survival through digestion, and manufacturing. Fermented vegetables may offer wider microbe variety; however, consistency in bacterial strains and stronger clinical evidence gives Greek yogurt significance in nutritional and microbiome research. Future investigations should focus on Greek yogurt and prioritize direct comparisons to other fermented foods. To credibly refine dietary recommendations, improved microbial methodologies and expanded trials among diverse populations are warranted.\n\nID: 42099859\nTitle: Complex food matrices reveal microbiota-nutrient balance interactions that modulate gut microbiome diversity in vitro.\nAbstract: Diet-microbiome relationships are often evaluated using isolated nutrients, yet microbes encounter complex food matrices in which nutrient accessibility and baseline microbial community context jointly shape gut fermentation outcomes. This study integrated an in vitro digestion and gut fermentation to examine the nutrient-baseline microbiota interaction to modulate community diversity. Nutrient-defined matrix classes were grouped using free saccharides, free amino acids, and free fatty acids content in food digesta. Two machine learning models-a classification model that predicted nutrient-defined matrix class from genus-level relative abundance changes (0-12\u202fh) and regression models that predicted \u03b1-diversity change using nutrient and baseline (0\u202fh) community features-were developed. SHAP-based feature attribution revealed that three nutrient-defined matrix classes exhibited distinct microbial response signatures (Turicibacter/Alistipes/Staphylococcus-centered), suggesting post-digestion nutrient associations with gut microbial restructuring patterns. However, \u03b1-diversity shifts within the same nutrient class were bidirectional, and inclusion of baseline microbiota features improved model performance for predicting diversity change from R2\u202f=\u202f0.34 to R2\u202f=\u202f0.72, consistent with a role for baseline-nutrient interactions. Fermented food matrices further illustrated that food-associated microbial contexts can modify restructuring trajectories beyond nutrient profiles. Overall, these findings propose that diversity outcomes during fermentation may depend on baseline-conditioned responses to bioaccessible nutrients, highlighting a matrix-specific but context-dependent diet-microbiome effects.\n\nID: 42039801\nTitle: Consumer knowledge and motivations for consumption of fermented foods.\nAbstract: Non-alcoholic fermented foods (FFs) are a popular food group with consumers; however limited studies exist evaluating the motivations for consuming FFs and the frequency of consumption. To begin to address this gap in knowledge, we developed an online survey to assess participant familiarity with different types of fermented products, determine consumption frequency, and gain insight into the motivation for consumption. A total of 751 participants completed the survey. Yogurt was the most frequently identified fermented food (n\u202f=\u202f658; 87.62% of respondents). Participants reported consuming fermented cereal grains (n\u202f=\u202f307; 46.17%), fruits and vegetables (n\u202f=\u202f281; 42.26%), dairy products (n\u202f=\u202f204; 39.70%), soy/rice products (n\u202f=\u202f250; 37.60%) and fermented meats (n\u202f=\u202f204; 30.68%). Reported daily consumption was highest for categories of fermented cereal and dairy products, compared to the other categories which typically were consumed on a weekly or monthly basis. The primary motivator for consumption was taste (n\u202f=\u202f337; 50.68%) compared to health benefits (n\u202f=\u202f235; 35.34%) and cultural reasons (n\u202f=\u202f80; 12.03%). The most highly selected health benefits associated with FF consumption were \"improved gut microbiome\" (n\u202f=\u202f513; 77.14%), \"digestive benefits\" (n\u202f=\u202f508; 76.39%), and \"probiotic\" (n\u202f=\u202f458; 68.87%). Participants associated health benefits with all fermented products listed in the survey. Therefore, consumers may assume that all fermented foods confer the same health benefits. The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved.\n\nID: 42029584\nTitle: The Nutritional Paradox of Obesity: Mechanisms and Clinical Implications of Micronutrient Deficiencies.\nAbstract: Background: Obesity is commonly seen as a condition of overnutrition; however, it is paradoxically associated with micronutrient deficiencies. These deficiencies are clinically relevant and may contribute to the progression of obesity-related comorbidities through interconnected pathways, including chronic low-grade inflammation, oxidative stress, gut dysbiosis, and impaired nutrient absorption. Objectives: This narrative review aims to summarize current evidence regarding the prevalence, underlying mechanisms, and clinical consequences of micronutrient deficiencies in individuals with obesity, with particular emphasis on their metabolic implications and potential therapeutic strategies. Results: Among individuals with obesity, iron, zinc, magnesium, calcium, vitamin D, vitamin B12, and folate are the most frequently reported deficiencies. These deficiencies arise from multiple mechanisms, including poor diet quality, increased metabolic demands, and compromised gastrointestinal absorption. In addition, obesity-related alterations in pharmacokinetics may further interfere with micronutrient distribution and bioavailability. Together, these mechanisms may lead to various clinical outcomes, such as anemia, immune, metabolic, and cardiovascular dysfunctions, along with cognitive impairment. Although several studies suggest that correcting these deficiencies may improve clinical outcomes, findings remain inconsistent, highlighting the complex and multifactorial pathophysiology underlying micronutrient imbalance in obesity. Conclusions: Micronutrient deficiencies represent frequently overlooked contributors to metabolic dysregulation in obesity. Their identification and correction should be considered a central part of the obesity management strategy. A personalized supplementation approach, based on clinical, biological, and pathophysiological characteristics, may provide a complementary support for weight-management treatments.\n\nID: 41995217\nTitle: Multi-omics reveals gut microbiome- and metabolome-specific responses to sugar alcohols.\nAbstract: The impacts of sugar alcohols (SA) utilized as low-calorie sweeteners on the gut microbiome and metabolome remain undefined. Among six SAs tested, isomalt, erythritol, xylitol and sorbitol significantly lowered fasting serum insulin and hepatic lipid levels in healthy rats, while mannitol and maltitol showed no such effect. Moreover, isomalt consumption lowered body weight gain, low-density lipoprotein and tumor necrosis factor-\u03b1, while improving high-density lipoprotein concentrations. All SAs effectively regulated gut microbiota composition and functionality. Most of the microbiota enriched by isomalt were short-chain fatty acid producers, including Faecalibaculum, Bacillus, Dubosiella and Anaerostipes, which led to a significant increase in the propionate proportion in faeces. The elevated Blautia and UCG-008 and lowered Akkermansia were the key specific responders to sorbitol, mannitol and maltitol. Notably, almost all SAs showed inhibitive efficacy on opportunistic pathogens such as Streptococcus, Staphylococcus and Ruminococcus. Dietary SAs significantly shifted stool and global metabolome profiles in rats. Isomalt and maltitol activated aldosterone-regulated sodium reabsorption and suppressed steroid hormone biosynthesis. Isomalt and sorbitol induced the thyroid hormone signaling pathway. Erythritol intake expressively triggered histamine metabolism, chemical carcinogenesis-receptor activation and folate biosynthesis. Xylitol, sorbitol and mannitol robustly promoted nucleotide metabolism, lysine biosynthesis and pyrimidine metabolism. Sorbitol and mannitol administration induced arginine biosynthesis, nicotinate and nicotinamide metabolism and terpenoid backbone biosynthesis. Additionally, stool metabolome suggested that mannitol intake attenuated ferroptosis in rats. Interestingly, structurally similar SAs, e.g. sorbitol, mannitol and maltitol, showed more shared microbiota and metabolites. This systematic comparative study identifies specific microbiota and associated metabolic pathways as responders to each SA and provides novel insights for future application in functional foods.\n\nID: 41989870\nTitle: Effects of concurrent Helicobacter pylori infection and small intestinal bacterial overgrowth on the gut microbiota and metabolic profiles: A multi-omics study.\nAbstract: This study investigated the synergistic effects of Helicobacter pylori (Hp) infection and small intestinal bacterial overgrowth (SIBO) on the gut microbiota structure and metabolic profiles and elucidate the underlying pathophysiological mechanisms. Forty-two patients with gastrointestinal symptoms were recruited and assigned to group A (Hp+ SIBO+), B (Hp+ SIBO-), C (Hp- SIBO+), or D (Hp- SIBO-) based on their Hp infection and SIBO status. Fecal samples were collected for metagenomic sequencing and untargeted metabolomic analysis. The associations between microbiota and metabolites were evaluated using alpha/beta diversity analysis, differential species screening, metabolite identification, and Procrustes/Spearman correlation analysis. Neither Hp infection nor SIBO significantly altered the alpha or beta diversity of the gut microbiota (both P > 0.05). However, specific shifts in microbial abundance were observed. Specifically, the abundance of short-chain fatty acid-producing bacteria such as Megamonas was significantly decreased in the SIBO+ groups. Metabolomic analysis revealed significant enrichment of inflammatory metabolites (e.g., prostaglandin derivatives) in group A, disordered bile acid conjugates (e.g., chenodeoxycholylisoleucine) and nucleotide metabolism in SIBO+ groups, and abnormal lipid/carbohydrate metabolism pathways in Hp+ groups. Multi-omics integration analysis indicated a strong coupling between the microbial structure and metabolic profiles (Procrustes analysis, P < 0.05). In group A, the abundance of Faecalibacterium and Hominenteromicrobium was negatively correlated with bile acid levels, suggesting impaired bile acid transformation. Hp infection and SIBO might synergistically exacerbate gut ecological and metabolic disorders by reshaping specific microbiota and metabolic networks (enhanced inflammatory response, disrupted bile acid circulation). Their co-occurrence produces additive effects, which could explain the aggravated clinical symptoms. This study provides a theoretical basis for interventions targeting microbiota-metabolite interactions, such as probiotics and bile acid modulators.\n\nID: 41989563\nTitle: The gut microbiome axis: how Lactobacillus-fermented soymilk orchestrates health.\nAbstract: Human culinary traditions have been deeply rooted in the consumption of fermented food products, offering health-promoting benefits. Among these, soymilk fermentation by lactic acid bacteria emerges as a captivating opportunity to produce enhanced soy-based flavor profiles with extended nutritional value. Among the numerous advantages, components of soymilk, such as isoflavone aglycones and peptides, show a hypolipidemic effect, thus proving beneficial to humans. Of central interest is Lactobacillus, a well-studied probiotic genus that exerts a pivotal role in the maintenance of gut barrier and microbial diversity. The interplay between gut microbiome and host physiology underscores its role in health and disease. Gut dysbiosis results from the interaction of environmental cues with host metabolic state, triggering pathological consequences. These range from irritable bowel syndrome and gastric cancer to neurological disorders. This review attempts to evaluate the knowledge surrounding fermented soymilk to shed light on the vital role of Lactobacillus in restoring a dysbiotic state within the gut microbiome. Further, we elucidate multifaceted mechanisms underlying the therapeutic potential of Lactobacillus-fermented soymilk. By exploring this complex interplay of microbial metabolites and host immune responses, and incorporating recent advancements in probiotic therapeutics, we emphasize the utilization of Lactobacillus-fermented soymilk as a dietary intervention to promote gut health and alleviate disease states.\n\nID: 41980519\nTitle: Luteolin ameliorates Escherichia coli-induced intestinal injury by modulating gut microbiota, metabolites and the TLR4/MyD88/NF-kB signaling pathway.\nAbstract: Luteolin, a naturally occurring flavonoid abundantly found in various fruits and vegetables, possesses anti-inflammatory and antioxidant properties. Its biological activities, including modulating immune responses and alleviating oxidative stress, make it a promising therapeutic candidate for inflammatory diseases. However, the precise role of this compound in mitigatingEscherichia coli induced (E. coli-induced) intestinal inflammation remains largely unexplored. More specifically, the mechanistic underpinnings by which it preserves intestinal mucosal barrier integrity, fine-tunes the activation dynamics of key mediators in intestinal inflammatory signaling cascades, and orchestrates the intricate crosstalk between intestinal microbiota homeostasis and host immune responses remain poorly elucidated. In this study, a total of 144 three-week-old specific pathogen-free (SPF) chickens were randomly divided into groups. An E. coli-induced enteritis model was subsequently established in these animals. Luteolin was administered at varying doses through the feed for a period of one week. The potential protective effects of luteolin against E. coli-induced intestinal damage were investigated from multiple aspects, including intestinal barriers function, gut microbiota composition, and differential metabolites profiles. Luteolin alleviated intestinal damage, enhanced survival rate and weight gain in chicken (P<0.05) and improved antioxidant capacity by reducing oxidative stress (P<0.05). It repaired intestinal barrier injury by upregulating the mRNA levels of tight junction proteins, and reduced intestinal inflammation by inhibiting the activation of the Toll-like receptor 4 nuclear (TLR4)/Myeloid Differentiation Primary Response Protein 88 (MyD88)/factor-\u03baB (NF-\u03baB) signaling pathway (P<0.05). In addition, luteolin reversed E. coli-induced gut microbiota dysbiosis, increasing the abundance of beneficial microorganisms such as Lachnospiraceae-Clostridium and Butyricimonas. Metabolomics analysis further revealed that luteolin partially corrected E. coli-induced metabolic disorders by modulating nucleotide metabolism (IMP, P<0.05), amino acid biosynthesis(arginine ornithine and lysine, P<0.05), and glutathione metabolism (S - lactoyl glutathione, P<0.05). Notably, a significant association was observed between gut microbiota and metabolic products (P<0.05). In summary, luteolin alleviates E. coli-induced enteritis in chickens via a multi-target mode of action that entails preserving gut microbiota homeostasis, restoring intestinal metabolic signatures, and suppressing the TLR4/MyD88/NF-\u03baB signaling cascade, which offers new perspectives for avian disease management and highlights its prospects as a safe antibiotic substitute.\n\nID: 41969654\nTitle: Megasphaera in the gut microbiome and cancer: from Megasphaera elsdenii dysbiosis to Megasphaera sp. XA511 in tumor microenvironments.\nAbstract: Growing evidence suggests that the gut microbiome and specific gut microbes influence carcinogenesis both within the gastrointestinal tract and in distant organs through immune, metabolic, and inflammatory pathways. Megasphaera elsdenii, a gram-negative-staining, strictly anaerobic member of the Veillonellaceae family, has been implicated in disruption of colonic epithelial homeostasis and may exert systemic effects beyond the intestine. While much attention has focused on the gut-brain axis, this mini-review synthesizes current evidence linking intestinal dysbiosis, microbial metabolite signaling, and immune crosstalk along the gut-lung axis. By integrating findings from studies on microbial translocation, mucosal immunity, and metabolite-mediated inflammation, we present a hypothesis-generating model in which M. elsdenii-driven gut dysbiosis may shape lung cancer pathogenesis through short-chain fatty acid-dependent immunometabolic signaling and hypothesized lymphatic and outer membrane vesicle-mediated pathways, recognizing that existing lung data derive solely from non-causal, genus-level 16S rRNA surveys. We further distinguish viable colonization from detection of immunogenic DNA and vesicular debris in distal tissues and discuss the context-dependent roles of the genus, contrasting the systemic pathogenicity of M. elsdenii in the gut-lung axis with the divergent, protective metabolic profile of a distinct gut-derived strain, Megasphaera sp. XA511, in pancreatic tumor microenvironments. This framework highlights Megasphaera as an understudied but potentially actionable modulator of cancer immunobiology.\n\nID: 41939722\nTitle: Food-derived molecules as regulators of intestinal tight junctions and barrier function: mechanisms and implications.\nAbstract: Controlling TJ permeability in the small intestine facilitates nutrient absorption, maintains luminal osmotic balance, and prevents the paracellular entry of pathogens. The pharmaceutical industry has leveraged the capacity of medium-chain fatty acids and their derivatives to transiently and reversibly open epithelial TJs in formulations to enable oral administration of therapeutic peptides, some of which have received regulatory approval or are progressing in advanced clinical trials. Other food-derived agent including chitosan and its analogues enhance mucoadhesion and also modulate TJ permeability in the intestine. Recently, pelargonidin, a polyphenolic pigment isolated from strawberries, has emerged as a promising food-derived TJ opener, facilitating oral insulin delivery in rat models. Conversely, other food or food-derived molecules reinforce TJ integrity while exerting antioxidant effects, thereby offering potential therapeutic benefits for conditions characterized by increased intestinal permeability including inflammatory bowel disease, sepsis, and coeliac disease. Examples of such agents include the short-chain fatty acid (SCFA), sodium butyrate, various essential and non-essential amino acids, fermented food, the trace element, zinc, and anthocyanins. The exploration of food-derived substances as modulators of intestinal epithelial TJ dynamics is still in its early stages but holds significant promise for future health applications.\n\nID: 41896654\nTitle: Characteristics of gut microbiota and metabolites in patients with metabolic dysfunction-associated steatotic liver disease and colorectal adenoma.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become one of the most prevalent chronic liver conditions worldwide, with its incidence steadily rising. However, the underlying mechanisms linking MASLD to colorectal adenoma remain unclear, and the role of gut microbiota and metabolites in this association requires further investigation. This study aims to characterise the gut microbiota and metabolites in patients with MASLD and colorectal adenoma. A cohort of 58 MASLD patients was enrolled and stratified into two groups based on colorectal adenoma status: the MASLD with colorectal adenoma group (M-CA group, n\u2009=\u200930) and the MASLD without colorectal adenoma group (M-NCA group, n\u2009=\u200928). The gut microbial ecosystem in the M-CA group showed significant dysregulation, evidenced by a decreased Gut Microbiome Health Index (GMHI) and significantly increased Microbiome Dysbiosis Index (MDI). Linear Discriminant Analysis Effect Size (LEfSe) identified 75 differentially abundant microbial taxa between groups, with Bacteroides vulgatus, Bacteroides ovatus, uncultured bacterium of norank genus of Muribaculaceae family, Muribaculaceae, and norank of Muribaculaceae family being significantly enriched in the M-CA group, representing potential microbial biomarkers for this cohort. Partial Least Squares Discriminant Analysis (PLS-DA) screened 116 differential metabolites. When combined with Random Forest (RF), Support Vector Machine (SVM) and Least Absolute Shrinkage and Selection Operator (LASSO) machine learning algorithms, 16 significantly identified biomarkers were discovered. The joint analysis of both omics revealed that variations in differential metabolite levels were associated with changes in specific microbiota abundances. Kyoto encyclopedia of genes and genomes (KEGG) functional prediction analysis indicated that the coordinated alterations in metabolites and microbiota may collectively influence multiple metabolic pathways, including lipid metabolism, xenobiotics biodegradation and metabolism, amino acid metabolism, carbohydrate metabolism, biosynthesis of other secondary metabolites and nucleotide metabolism. This study revealed that patients with MASLD and colorectal adenoma exhibited significant alterations in the gut microbiota composition and metabolic profile, indicating potential impacts on associated metabolic pathways. These findings provided novel insights and a foundation for future research into potential intervention strategies for this clinical complication.\n\nID: 41878551\nTitle: Gut Microbiota Influence Host Metabolism and Immune Responses in Atopic Dermatitis: A Next-Generation Sequencing-Based Functional Profiling Study.\nAbstract: Gut dysbiosis has been linked to immune imbalance in allergic diseases, but the underlying mechanisms remain unclear. We aimed to verify whether gut microbiota composition is associated with cellular, metabolic, and immune pathways in atopic dermatitis. Fifty adults with atopic dermatitis and 25 sex- and age-matched healthy controls were enrolled. Gut microbiome composition was assessed using V3-V4 16S rRNA sequencing. Functional pathways were inferred from microbiome data using PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States). Despite only subtle differences in microbiota composition between patients with atopic dermatitis and controls, PICRUSt analysis identified significant differences in 149 functional pathways. Key pathways enriched in atopic dermatitis involved signal transduction mediated by protein kinases, as well as carbohydrate and lipid metabolism. Downregulated pathways included those related to energy metabolism, amino acid and nucleotide metabolism, antigen processing, and innate immune responses. In patients with atopic dermatitis, microbial diversity increased with EASI scores and IgE levels, correlating with additional predicted functional shifts. Our results suggest that even subtle structural differences in gut microbiota may exert significant functional effects in atopic dermatitis. Altered pathways could contribute to immune imbalance and impaired epidermal barrier function. These findings underscore the importance of incorporating functional analyses into future gut microbiota studies of atopic dermatitis to help identify therapeutic targets, including candidate probiotic strains for supplementation. Bacteria living in the gut, known as the gut microbiome, may play a role in the development of certain diseases. Changes in the diversity and composition of the gut microbiome have been linked to atopic dermatitis, a skin condition that causes itchy lesions and greatly affects quality of life. However, few studies have examined how gut bacteria may influence metabolism and immune responses in people with atopic dermatitis. In our study, we analyzed the gut microbiome of 50 adults with atopic dermatitis and 25\u00a0healthy individuals using sequencing methods and a software tool called PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States). Despite only subtle differences of microbiome composition between the groups, PICRUSt predicted changes in many metabolic, cellular, and immune-related pathways. These included carbohydrate, lipid, and amino acid metabolism, innate immune responses, and signal transduction pathways that may contribute to inflammation and skin barrier problems seen in atopic dermatitis. Our findings suggest that even when overall microbiome diversity appears similar, subtle changes in gut bacteria may still have important effects on metabolism and immune function. Future studies should combine microbiome and metabolic analyses to confirm these results and may help guide targeted treatments, such as probiotic supplementation.\n\nID: 41829032\nTitle: Compound Probiotics Alleviate Gut Microbiota Dysbiosis Induced by Heat Stress in Broilers.\nAbstract: Heat stress represents a key environmental challenge in poultry production, markedly impairing broiler health and productivity. This study investigated the association between compound probiotic supplementation and the gut microbial community structure in heat-challenged broilers, analyzing the cecal contents from both groups using 16S rDNA amplicon sequencing. Compound probiotic supplementation was associated with changes in alpha diversity and richness of the cecal microbiota, with lower Shannon, Chao1, and ACE indices (p < 0.05). At the phylum level, compound probiotic supplementation significantly increased the relative abundance of Bacteroidota (p < 0.001) while decreasing that of Proteobacteria (p < 0.0001) in the cecum of broilers, whereas the relative abundances of Firmicutes and Verrucomicrobiota showed increasing trends. At the genus level, the relative abundance of Bacteroides (p < 0.0001) was significantly increased in the HP group, whereas Lactobacillus and Fusobacterium exhibited decreasing trends compared with the HS group. LEfSe analysis suggested Verrucomicrobia as a potentially enriched taxon in the HP group. Furthermore, KEGG level 3 functional prediction suggested enrichment of predicted pathways related to starch and sucrose metabolism, as well as amino acid and nucleotide metabolism in the HP group. These findings suggest that compound probiotics are associated with changes in gut microbial composition and predicted functions in heat-stressed broilers, providing preliminary, exploratory insights into their potential associations under heat stress.\n\nID: 41827072\nTitle: Gut microbiome changes in people with diabetic retinopathy in India. DRMS-India report # 1: operational protocol and trends from first 100 participants.\nAbstract: Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus (DM), and the leading cause of vision impairment and blindness. India is among the top three countries in DM prevalence, and both DM and DR are projected to rise sharply in the future. There is no accepted strategy for the prevention of DR other than DM control. Recent studies suggest that DM is associated with alterations in a core group of gut microbiota, and progression to DR may be influenced by changes within this core group, highlighting a potential link between DR and gut microbiome. We studied these changes in a protocol-driven large case-control study, the Diabetic Retinopathy Microbiome Study-India (DRMS-India: CTRI/2024/02/062511), analysed the results of the first 100 individuals, and evaluated variations in gut microbiome in DR. The DRMS is designed to recruit 462 people aged\u2009\u2265\u200930 years into three cohorts: healthy controls (HCs), DM, and DR, at 17 independent sites in India. Shotgun metagenomic sequencing of first-pass morning fecal samples is performed at a centralized laboratory and correlated with disease status, lifestyle, dietary, and systemic factors. The first 100 participants included 26 HC, 33 DM, and 41 DR. The trends showed the DR group had 1, 6, and 10 unique core phyla, genera, and species, respectively. Alpha diversity was highest in the DR group; Beta diversity plots showed separate clusters of HCs and DR, with DM overlapping both. Firmicutes (highest in DR), Proteobacteria (highest in DM), Bacteroidetes, and Actinobacteria (highest in HC) were common phyla. Segatella was the most common genus, and Segatella copri was the most common species across all groups to date. Most microbial gene families were annotated to Molecular Functions (MF), and the pathways attributed to carbohydrate, amino acid, lipid, and nucleotide metabolism, indicating distinct functional adaptations in their gut microbiome. Trends from the first 100 individuals indicate that the gut microbiome of Indians with DR exhibits discriminatory features in microbial diversity and abundance, as well as in gene families and pathways that impact host gut metabolism. Data trends from DRMS-India indicate a region-specific non-invasive biomarker that may guide preventive therapy for DR.\n\nID: 41794480\nTitle: Modulation of intestinal microbiota and metabolites mediates the improvement of cyclophosphamide-induced immunodeficiency in mice by Monopterus albus slime protein.\nAbstract: Immunodeficiency significantly compromises host defense mechanisms and contributes to various pathologies. Monopterus albus whole slime (MS) is an underutilized aquatic by-product rich in proteins. This study examined the therapeutic effects and underlying mechanisms of MS and its purified protein (MSP) against cyclophosphamide (CTX)-induced immunodeficiency in mice. The results revealed that MSP significantly increased body weight, immune organ indices (spleen and thymus), cellular immune parameters (including counts of WBC, PLT, lymphocyte, and granulocyte), and humoral immune markers (including serum levels of IFN-\u03b3, IL-2, and IgA) in immunocompromised mice. Furthermore, MSP demonstrated superior efficacy compared to MS in promoting thymic recovery and enhancing IgA production (p\u00a0<\u00a00.05). Concurrently, MSP ameliorated intestinal integrity through improved villus structure, upregulation of tight junction proteins (ZO-1 and occludin), attenuation of oxidative stress (evidenced by decreased MDA level and increased SOD and GSH-Px activities), and elevated secretory IgA (SIgA) levels. Gut microbiota analysis indicated that MSP promoted the enrichment of beneficial bacterial genera (norank_f__Muribaculaceae, Muribaculum) while suppressing pathogenic bacteria (Desulfovibrio, Lachnospiraceae_UCG-006, Eubacterium_xylanophilum_group). Fecal metabolomic analysis revealed that both MS and MSP altered the profiles of various metabolites, with enriched pathways involved in nucleotide metabolism, ABC transporters, and taurine and hypotaurine metabolism. Collectively, these findings suggest that MSP may mitigate CTX-induced immunodeficiency through a potential \"gut microbiota-metabolite-intestinal barrier\" axis, thereby establishes the theoretical groundwork for the development of slime-derived proteins as potential immunomodulatory agents.\n\nID: 41780875\nTitle: Lacto-N-neotetraose and Bifidobacterium longum ssp. infantis together shape the unique gut microbiota and metabolites of allergic mice.\nAbstract: Food allergies are a major challenge in current healthcare. Probiotics and human milk oligosaccharides (HMO) are increasingly being used to address food allergies. However, the role of nonfucosylated neutral oligosaccharides in food allergies remains unclear. Moreover, HMO interact positively with probiotics, but the synergistic effects and underlying mechanisms of their combined action in alleviating food allergies remain poorly understood. Consequently, Bifidobacterium longum ssp. infantis (B. infantis), which exhibits the greatest capacity to use HMO, was chosen for this study. The effects of lacto-N-neotetraose (LNnT), B. infantis, and their combination on allergy was assessed using an ovalbumin (OVA)-induced allergic mouse model. The mechanisms underlying the alleviation of food allergies by LNnT + B. infantis were also investigated through genomics and metabolomics. The results demonstrated that LNnT and B. infantis exerted partial modulatory effects on allergic symptoms, BW, mast cell degranulation, cytokine levels, and immune cell populations in mice. Notably, the simultaneous administration of LNnT and B. infantis significantly outperformed the administration of either LNnT or B. infantis alone, indicating a synergistic effect. Furthermore, LNnT + B. infantis was found to alleviate intestinal injury. Gut microbiota analysis revealed that LNnT + B. infantis reduced the abundance of the allergy-associated bacterium Desulfovibrio and significantly increased the levels of beneficial bacteria, including Lactobacillus, Limosilactobacillus, and Blautia. The LNnT + B. infantis treatment also enhanced steroid hormone biosynthesis, ascorbate and aldarate metabolism, and nucleotide metabolism. Some substances in these pathways are produced by the gut microbiota and are linked to allergy amelioration. In conclusion, LNnT + B. infantis alleviates food allergies by modulating the gut microbiota and its associated metabolic functions in OVA mice.\n\nID: 41720241\nTitle: CuO nanoparticles trigger cuproptosis-linked mitochondrial damage and gut Microbiota-Metabolome disruption in zebrafish.\nAbstract: Copper oxide nanoparticles (CuO NPs), with their superior catalytic activity, antimicrobial performance and photoelectric properties, are widely used in production and daily life, thereby increasing their environmental release risk. Compared with the well-studied effects of ionic copper, the chronic toxicity of CuO NPs remains largely overlooked. In this study, zebrafish were exposed to environmentally relevant concentrations (5\u00a0mg/L Cu) of CuO NPs or copper sulfate (CuSO4) to systematically evaluate intestinal toxicity induced by long-term exposure to different forms of copper. An integrated strategy incorporating ultrastructural analysis, biochemical assays, gut microbiota profiling, and metabolomic analysis was employed. Both copper forms induced mitochondrial damage, metabolic perturbations, and gut microbial dysbiosis in intestinal epithelial cells. However, CuO NPs showed markedly stronger intestinal toxicity than ionic copper. Specifically, CuO NPs can directly penetrate mitochondria in particulate form, impair mitochondrial structure, and potently activate the FDX1-LIAS-DLAT cuproptosis pathway, thereby triggering significant disturbances in amino acid, lipid, and nucleotide metabolism. Furthermore, CuO NPs exerted a more robust impact on the bidirectional gut microbiota-host metabolite interactions. In conclusion, this study clarifies form-dependent differences in copper-induced intestinal toxicity and highlights the critical role of microbiota-metabolite crosstalk in CuO NP-mediated adverse effects. These findings yield critical mechanistic insights and provide a robust scientific basis for evaluating the potential health risks posed by chronic exposure to CuO NPs.\n\nID: 41687784\nTitle: Impact of Yogurt and Rolled Oats Consumption on the Gut Microbiome: A Randomized Crossover Study Displaying Individual Responses and General Resilience.\nAbstract: Yogurt and rolled oats are commonly linked to gut health through probiotic and prebiotic effects, but these potential benefits remain insufficiently studied, especially in healthy individuals. This study primarily aimed to investigate the effects of daily yogurt and rolled oats consumption on gut microbial composition. Secondary outcomes included stool metabolites and blood-based health markers. In this randomized, open-label, 2-period crossover trial, 119 healthy participants were randomly assigned to 1 of 2 sequences: 250 g of yogurt daily followed by 250 g of yogurt with 50 g of rolled oats, or the reverse with a washout period in between. Stool and blood samples were collected at baseline and post intervention. Metagenomic sequencing and metabolomic analyses were conducted on stool samples, whereas health markers related to metabolic control, inflammation, immune response, oxidative stress, and gut permeability were assessed in the participants' blood. Of the 119 randomly divided participants, 110 completed the study (53 yogurt first, 57 yogurt and rolled oat first). Yogurt consumption transiently increased yogurt-associated bacteria, with Streptococcus thermophilus rising from absent to 0.97% [95% confidence interval (CI): 0.71, 1.26] in the yogurt intervention and 0.79% (95% CI: 0.58, 1.03) in the yogurt with oats intervention. In a small Prevotella-predominant subgroup (n = 8), adding rolled oats increased microbial evenness (q < 0.001) and reduced interindividual divergence (q < 0.05), suggesting a temporary slight homogenization. No additional effects on fecal short-chain fatty acids concentrations or human health markers were identified. Functional metagenomic changes were mainly driven by yogurt-derived bacterial enrichment. A healthy gut microbiota is largely stable and resilient to short-term diet changes, yet individual differences highlight the importance of personalized dietary recommendations.

This study\u00a0aims to elucidate the therapeutic mechanisms of iTBS and cTBS for ASD. METHODS: Prenatal valproic acid-induced ASD rats were established and were randomized into VPA, VPA\u2009+\u2009iTBS, and VPA\u2009+\u2009cTBS groups, with a saline group as control. Core and comorbid ASD behaviors in rats were assessed. Multi-omics analyses included 16\u00a0S rRNA sequencing of cecal contents, non-targeted fecal metabolomics, and prefrontal cortex transcriptomics. Key pathways were validated via Western blot, ELISA, and immunofluorescence. Integrative analyses correlated multi-omics data with neuroendocrine findings. RESULTS: Behavioral assessments demonstrated that both iTBS and cTBS significantly ameliorated social deficits and repetitive behaviors in VPA-exposed rats. However, protocol-specific effects on comorbidities were observed: cTBS, but not iTBS, effectively alleviated anxiety-like behaviors, whereas iTBS, but not cTBS, significantly improved learning and memory. The multi-omics approach demonstrated that iTBS primarily modulated inflammatory immune responses and energy metabolism, while cTBS predominantly regulated oxidative stress, lipid metabolism, and nucleotide metabolism. Both interventions suppressed the hyperactivated PI3K/AKT/mTOR signaling pathway, an effect potentially linked to the normalization of hypothalamic-pituitary axis function. Furthermore, we identified a potential interplay between the GH/IGF-1 axis and the gut microbiome in ASD, which was differentially modulated by iTBS and cTBS. CONCLUSION: iTBS modulated inflammatory-immune responses and energy metabolism, while cTBS regulated oxidative stress, lipid metabolism, and nucleotide metabolism. The inhibition of the central GH/PI3K/AKT/mTOR pathway by both protocols may involve their specific regulation of distinct gut microbiota communities.\n\nID: 41572685\nTitle: Preliminary Study on Laboratory Indicators and Gut Microbiota Differences between Genders with Gastrointestinal Inflammation.\nAbstract: The human gastrointestinal tract is home to a vast array of microorganisms, and the imbalance of these microorganisms is closely linked to various diseases. The composition of gut microbiota in individuals is influenced by many factors, among which gender differences are often overlooked and lack targeted treatment plans in clinical practice. Based on this, we conducted this study aimed at exploring the pathogenesis of gastrointestinal inflammation and the importance of gender specificity, providing new ideas and targets for the diagnosis and treatment of gastrointestinal inflammation stratified by gender. We collected fecal samples from 89 patients with gastrointestinal inflammation (40 males and 49 females) for DNA extraction, DNA library construction, sequencing, and clinical data analysis. In laboratory indicators, male patients had significantly lower mean LDH levels than females (P < 0.05), whereas median GGT, HB, M, and E values were significantly higher (P < 0.05). Additionally, significant differences in microbial \u03b1 diversity at the species level were observed between the two groups (all P < 0.05). In the prediction analysis of microbial population function, the mean values of heterologous biodegradation and metabolism, signal transduction, cell activity, metabolism of other amino acids, and bacterial infectious disease pathways in the female patient group were higher than those in the male patient group (all P<0.05), and the mean values of nucleotide metabolism, replication and repair, and transcription and translation were lower than those in the male patient group (all P<0.05). Gender differences affect gastrointestinal inflammation progression, with male and female patients showing distinct gut microbiota and laboratory indicators. Males have lower LDH but higher GGT, HB, M, and E, linked to hormonal effects. The gut microbiome composition differs by gender, with males having a higher prevalence of Prevotella and altered metabolic pathways. Females show higher activity in xenobiotic degradation and infection-related functions. Diet, exercise, and clinical interventions, such as FMT, can modulate the microbiota, but gender-specific responses exist. Analysis revealed significant sex-based differences in gastrointestinal disease patients, including variations in laboratory indicators (LDH, GGT, HB, M, E), gut microbiome composition and diversity, and predicted microbial functional profiles. This provides insights for precise medical treatment of gastrointestinal inflammation stratified by gender.\n\nID: 41550492\nTitle: Analysis and characterization of a novel metallophosphoesterase from Akkermansia muciniphila involved in lipid degradation.\nAbstract: Gut microbes play an important role in the regulation of host health. Multiple studies have shown that Akkermansia muciniphila, as a promising beneficial gut bacterium, is robustly associated with positive effects on host metabolism, immunological regulation, and its presence inversely correlates with body weight. But the precise function played by this bacterium underlying lipid degradation is still unknown. Here we identify a metallophosphoesterase from A. muciniphila. The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies.\n\nID: 41547444\nTitle: 3'-Sialyllactose ameliorates antibiotic-associated diarrhea by shaping unique gut microbiota and metabolite composition.\nAbstract: 3'-Sialyllactose (3'-SL) is a naturally occurring prebiotic in milk, known to regulate intestinal microbiota and prevent diseases. However, the mechanisms through which 3'-SL alleviates antibiotic-associated diarrhea remain poorly understood. In this study, an antibiotic-associated diarrhea model was established through the co-administration of ampicillin and neomycin. The effects of 3'-SL supplementation on diarrhea phenotype, inflammation, intestinal permeability, and barrier function were examined in antibiotic-associated diarrhea-model mice. Moreover, gut microbiota composition, metabolite profiles, and their alterations were analyzed using genomic and metabolomic approaches. The results demonstrate that 3'-SL increased body weight and aquaporin (AQP) 3 and AQP4 levels but reduced diarrhea rate, cecal mass, and fecal water content in the model mice, indicating its therapeutic effect on diarrhea. Furthermore, 3'-SL reduced serum levels of IL-6, tumor necrosis factor (TNF)-\u03b1, and IL-1\u03b2, while increasing IL-10 levels in the mice. Moreover, 3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice. 16S rRNA analysis revealed that mice in the 3'-SL group exhibited greater abundances of Akkermansia, Bacteroides, and Dubosiella, along with a reduced relative abundance of the diarrhea-associated bacterium Alloprevotella. Furthermore, metabolomics analysis indicated that 3'-SL promoted enrichment of purine metabolism, pyrimidine metabolism, nucleotide metabolism, and the pentose phosphate pathway, which may be associated with diarrhea development, inflammation amelioration, and barrier regulation. In conclusion, our findings suggest that 3'-SL ameliorates antibiotic-associated diarrhea by modulating gut microbiota and metabolite profiles.\n\nID: 41502854\nTitle: Blastocystis presence alters gut archaeal communities and metabolic functions in Tibetan antelopes (Pantholops hodgsonii).\nAbstract: Archaea are vital members of the gut microbiota, yet their diversity and functions in high-altitude wildlife remain poorly understood. Understanding their ecological roles can provide insights into host health and microbial community dynamics. We applied metagenome-assembled genome (MAG)-based approaches to investigate gut archaea in Tibetan antelopes (Pantholops hodgsonii) and assess their shifts in the presence of Blastocystis. A total of 463 non-redundant archaeal MAGs were reconstructed and analyzed for taxonomic diversity and functional potential. The MAGs encompassed 16,189 protein clusters, with over 70% representing potentially novel species, highlighting substantial unexplored archaeal diversity. Alpha diversity showed no significant differences between healthy and Blastocystis-present groups, but beta diversity analysis revealed marked community restructuring, including decreased Methanobacteriota and increased Halobacteriota and Thermoplasmatota in the Blastocystis-present group. Functional annotation indicated changes in energy and nucleotide metabolism and alterations in carbohydrate-active enzyme composition. Additionally, putative viral sequences were detected within archaeal MAGs, suggesting potential virus-microbe interactions. Our findings provide novel insights into the diversity and ecological functions of gut archaea in Tibetan antelopes, offering a foundation for future research on their contributions to host health and microbial ecology.\n\nID: 41428219\nTitle: Research Advances on the Impact of Gut Microbiota on COPD: Exploring New Perspectives on the Microbiota-Gut-Lung Axis.\nAbstract: Chronic obstructive pulmonary disease (COPD), the third leading cause of mortality worldwide, is a heterogeneous disorder characterized by airway inflammation and progressive decline in lung function. While current therapies provide symptomatic relief, they fail to modify disease progression, with early diagnosis remaining challenging due to nonspecific clinical presentations. Emerging evidence has established the gut microbiota as a vital modulator of COPD pathogenesis via the microbiota-gut-lung axis, which is mediated through dysregulated short-chain fatty acid metabolism, bidirectional inflammatory cytokine regulation, and compromised mucosal barrier integrity. Clinically, COPD patients exhibit significantly reduced gut microbial diversity, and the dynamic Bacteroidetes/Firmicutes ratio has emerged as a promising early diagnostic biomarker. This comprehensive review synthesizes recent five-year evidence to elucidate gut-lung axis mechanisms, identify novel microbial biomarkers for early prediction, and evaluate microbiota-targeted therapeutic interventions, ultimately providing new scientific frameworks for developing targeted strategies for COPD prevention and clinical management.\n\nID: 41425618\nTitle: Nutritional strategies in supporting immune checkpoint inhibitor, PI3K inhibitor, and tyrosine kinase inhibitor cancer therapies.\nAbstract: Nutritional status of patients undergoing cancer treatment has been associated with cancer therapy and survival outcomes across multiple therapy types. Targeted therapies, including immune checkpoint inhibitors (ICIs), phosphatidylinositol 3-kinase (PI3K) inhibitors and EGFR-tyrosine kinase inhibitors (TKIs), are both influenced by and themselves influence the patients' nutritional and metabolic status. Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount. Rational individualized approaches based on detailed and dynamic clinical assessment of patient-, cancer- and treatment-related factors, using validated prognostic scores and biomarkers, are needed to maximize the potential of precision nutrition now and in future trials in this arena.\n\nID: 41420986\nTitle: Combined exposure to microplastics and cadmium alters gut microbiota composition in preschool children: A cross-sectional study.\nAbstract: Early childhood is a critical developmental stage during which the gut microbiota strongly influences nutrient absorption, immunity, and neurodevelopment. Diet is considered a primary route of exposure to both microplastics (MPs) and cadmium (Cd), raising concerns about their potential joint impacts on child health. However, the effects of combined exposure to MPs and Cd on the early-life gut microbiota remain poorly understood. Fecal samples from 68 preschool children under 6 years of age were analyzed using pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) and inductively coupled plasma mass spectrometry (ICP-MS) to quantify MPs and Cd, respectively. MPs were detected in all samples, with a median concentration of 123.7\u202f\u03bcg/g dry weight (DW) (interquartile range, IQR: 70.6-197.8). The predominant polymers were polyethylene (PE, 100\u202f%), polyamide-66 (PA66, 100\u202f%), and polyvinyl chloride (PVC, 93\u202f%). Cd was also detected in all children, with a median concentration of 0.31\u202f\u03bcg/g DW (range: 0.21-0.48). Cd concentrations were significantly higher in the low-MP-exposure group compared to the high-exposure group, indicating an inverse association between fecal MP and Cd levels in children. Under combined exposure to MPs and Cd, children with lower Cd levels exhibited higher abundances of beneficial taxa, such as Bifidobacterium and Faecalibacterium. In contrast, higher MP exposure was associated with enrichment of Bacilli and enhanced Bacilli-associated functional activity, particularly in amino acid, energy, and carbohydrate metabolism. KEGG functional predictions also showed that carbohydrate and nucleotide metabolism pathways are more prominent in both low Cd-MP and high Cd-MP exposure groups, indicating a non-monotonic trend. These findings provide novel evidence that combined exposure to MPs and Cd is associated with distinct alterations in the gut microbiota of preschool children, underscoring the need to consider multiple pollutants in early-life microbiome research.\n\nID: 41211757\nTitle: Characterizing gut microbiota and fecal metabolites in intervertebral disc degeneration: insights into the gut-disc axis.\nAbstract: This study aims to delineate the characteristic profiles of gut microbiota and fecal metabolites in individuals diagnosed with intervertebral disc degeneration (IDD), potentially elucidating the gut-disc axis as a novel perspective for understanding IDD pathophysiology. Fecal samples were collected from 15 patients diagnosed with IDD, classified according to the Pfirrmann grading system, with a distribution of three individuals per grade. Additionally, samples were obtained from five healthy controls for comparative analysis. 16S\u00a0rDNA sequencing was employed to analyze gut microbiota composition, while liquid chromatography-mass spectrometry was used for untargeted metabolite profiling. Distinct gut microbiota signatures were observed in IDD patients compared to controls, characterized by a dysbiotic state with increased biodiversity. More importantly, patients with IDD exhibit a higher abundance of Proteobacteria and Fusobacteriota, along with reduced abundances of Campilobacterota and Synergistota at the phylum level, as determined by Linear Discriminant Analysis Effect Size (LEfSe). Fecal metabolite analysis revealed an altered metabolic profile in IDD patients, including aggrandized levels of lipids and lipid-like molecules, which are associated with oxidative stress and tissue degradation. KEGG pathways identified five significant ones, including Nucleotide metabolism, Taurine and hypotaurine metabolism, Arginine and proline metabolism, Carbohydrate digestion and absorption, and FoxO signaling pathway. Together with receiver operating characteristic analysis, our data indicate that the upregulation of Permethrin and the reduction of 3ccPA, Thymine, His-ser, Hypoxanthine, N6-Acetyl-L-lysine, Safranin, and Peimine are highly associated with IDD. Our findings suggest a strong association between gut microbiota dysbiosis and fecal metabolite alterations in the pathogenesis of IDD.\n\nID: 41199512\nTitle: A CRISPRi Gene Regulation System for Bifidobacteria.\nAbstract: This work describes the development of a CRISPR interference (CRISPRi) system for targeted gene repression in bifidobacteria. We first validated the CRISPRi-based approach using Bifidobacterium breve strains engineered to express nuclease-dead orthologs of Cas9 and demonstrated that the CRISPR-Cas system from Streptococcus thermophilus is efficient at targeting both reporter and endogenous genes through the use of single guide RNAs corresponding to the gene of interest. We also developed a one-plasmid system for targeted gene repression in bifidobacteria and demonstrated its utility by targeting genes involved in nucleotide metabolism and carbohydrate metabolism in several species of bifidobacteria. Efficient gene repression was achieved across all tested bifidobacterial species without the requirement for extensive optimization of transformation parameters or sequence optimization to avoid restriction modification systems thus removing the key barriers to genetic manipulation in this genus. This CRISPRi system provides a novel approach to functional genomics in bifidobacteria which facilitates future mechanistic studies in these commercially important microbes.\n\nID: 41066744\nTitle: Yi-Qi-Xuan-Fei Formula ameliorate chronic obstructive pulmonary disease by remodeling lung and intestinal florase in rat models.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by various pathological lesions and an imbalance in the microflora. The Yi-Qi-Xuan-Fei Formula (YQXF) is a clinically effective formula with pharmacological potential to delay the progression of COPD. This study aims to explore the relationship between the therapeutic mechanism of YQXF and the microflora in COPD. Our study found that YQXF reduces inflammatory injury and inflammatory cell infiltration in lung tissue, repairs the intestinal mucosal barrier, and enhances immune function. Additionally, YQXF regulates the pulmonary and intestinal flora by increasing the abundance of Alloprevotella, Roseburia, Oscillibacter, and Lactobacillus, while reducing the abundance of Fusobacterium, Escherichia/Shigella, and Clostridium sensu stricto. Moreover, YQXF elevates the levels of short-chain fatty acids, which are produced by the intestinal flora. In conclusion, our findings demonstrate that YQXF reduces inflammation levels in lung tissue and repairs the intestinal barrier in COPD rats. Furthermore, the anti-inflammatory and tissue damage prevention effects of YQXF are based on its intervention in the pulmonary and intestinal flora. These findings provide valuable insights into the fundamental mechanism of the herbal formula YQXF and suggest that specifically targeting the intestinal flora could be a potential therapeutic approach for COPD.\n\nID: 41049420\nTitle: Recovery of Proteins and Bioactive Peptides From Potato Peels.\nAbstract: Potato peels, a significant byproduct of the potato processing industry, hold immense potential for sustainable utilization due to their rich composition of proteins, bioactive peptides, dietary fibers, and phenolic compounds. These components not only present opportunities for functional food development but also align with the principles of a circular economy by reducing waste and creating value-added products. This review provides a comprehensive synthesis of current knowledge on potato peel proteins and bioactive peptides, covering extraction and purification methods, health-promoting properties, and technological applications. Recent advances in enzymatic hydrolysis and membrane separation are discussed, along with the functional properties and health benefits of derived peptides, including antioxidant, anti-inflammatory, antihypertensive, and antidiabetic activities demonstrated in in\u00a0vitro and in\u00a0vivo models. While enzymatic production methods are well studied, alternative approaches such as autolysis and fermentation remain underexplored and merit further investigation. The review also addresses food safety concerns associated with glycoalkaloids and protease inhibitors present in potato peels. Despite current challenges-such as low protein content, bitter taste, and limited bioavailability-integrated valorization strategies can enhance their economic and functional potential. Overall, potato peel-derived proteins and peptides emerge as promising candidates for the development of functional foods and nutraceuticals, with future research needed to unlock their full application potential.\n\nID: 41032951\nTitle: Exploration of microorganism and metabolites relation to the egg production of Shanma ducks based on 16S rRNA gene sequencing and metabolomics.\nAbstract: Gut microbiota and metabolites play crucial roles in regulating poultry health, metabolism, and egg-laying performance. To elucidate the biological basis underlying differences in laying performance, this study employed 16S rRNA high-throughput sequencing and untargeted liquid chromatography-mass spectrometry (LC-MS/MS) to analyze the gut microbiota and serum metabolome of low-producing (LP) and high-producing (HP) Shanma ducks. The LP and HP groups exhibited significant differences in egg production performance, body size parameters, and slaughter traits. Firmicutes were the dominant phylum in the gut microbiota of both groups. However, Actinobacteria were significantly enriched in the HP group, while Campylobacter was more abundant in the LP group. Correlation analysis revealed a negative association between Campylobacter abundance and egg production, whereas Corynebacterium (belonging to Actinobacteria) showed a positive correlation. Non-targeted serum metabolomic analysis indicated that the differentially expressed metabolites were primarily enriched in nucleotide metabolism, choline metabolism, and glycerophospholipid metabolism pathways. Notably, Campylobacter abundance was negatively correlated with the levels of key metabolites involved in these pathways. Mantel analysis further confirmed a strong correlation between egg production and both gut microbiota composition and serum metabolomic profiles. Collectively, these findings provide new insights into the microbial and metabolic determinants of reproductive performance in ducks, offering a foundation for genetic selection and microbiota-targeted nutritional strategies to enhance laying efficiency in Shanma ducks.\n\nID: 41019167\nTitle: Astaxanthin Alleviates Lead-Induced Toxicity by Restoring Hepatic and Gut-Liver Axis Homeostasis Through Multidimensional Metabolic and Antioxidative Pathways.\nAbstract: Lead (Pb) poisoning is a major public health concern of environmental origin in the world. It is essential to develop effective ways such as utilizing natural products as therapeutic agents for prevention and therapy of Pb-induced diseases. This study explores the effects and underlying mechanisms of astaxanthin (ATX), a natural compound with potent antioxidant properties, in alleviating Pb-induced toxicity in model mice. Supplementation with ATX significantly ameliorated lead-induced physiological and biochemical disruptions, including weight loss, hepatic and renal damage, and metabolic imbalances. Metabolomic and transcriptomic analyses revealed that ATX played a positive role in improving redox homeostasis, regulating lipid, amino acid, and nucleotide metabolism, and activating critical pathways such as Nrf2/ARE, PPAR, and S1P, thereby enhancing the antioxidative, anti-inflammatory, and detoxification capacities of the mice. ATX supplementation also modulated mouse gut microbiota by promoting beneficial bacterial populations, suppressing harmful strains, and increasing short-chain fatty acid production, thereby effectively restoring gut-liver axis balance. These findings demonstrate that ATX possesses comprehensive activities against lead toxicity via multi-dimensional regulatory mechanisms, highlighting ATX as a promising therapeutic agent for heavy metal poisoning. Further research is warranted to validate the clinical applications of ATX and evaluate its long-term safety.\n\nID: 41010470\nTitle: Lycium ruthenicum Murr. Polysaccharide Attenuated Inflammatory Response and Intestinal Flora Dysbiosis in LPS-Induced Acute Lung Injury in Mice.\nAbstract: Background/Objectives: Acute lung injury (ALI) represents a life-threatening respiratory syndrome characterized by dysregulated pulmonary inflammation, alveolar-capillary barrier dysfunction, and gut-lung axis impairment. Although Lycium ruthenicum polysaccharide (LRP) possesses documented anti-inflammatory properties, its role in ALI remains systematically unexplored. This study aimed to investigate the protective effects of LRP against lipopolysaccharide (LPS)-induced ALI. Methods: In vitro, A549 cells were subjected to injury induction with 10 \u03bcg/mL LPS. In vivo, male C57BL/6J mice were randomly allocated to four groups and, respectively, administered 100 mg/kg LRP, 400 mg/kg LRP, or normal saline for 7 days prior to ALI induction via intratracheal LPS instillation (5 mg/kg). Results: LRP restored viability in LPS-injured A549 cells and attenuated their inflammatory responses. Histopathological analysis demonstrated that high-dose LRP (H-LRP) significantly reduced alveolar collapse and inhibited inflammatory cell infiltration in bronchoalveolar lavage fluid (BALF) compared to the LPS group. The H-LRP group exhibited marked downregulation of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6) concomitant with upregulation of the anti-inflammatory cytokine IL-10. Intestinal microbiome sequencing confirmed LRP-mediated restoration of gut microbiota homeostasis, evidenced by a 2.2-fold increase in commensal Bacteroides and decreased abundance of pathogenic Escherichia-Shigella. Conclusions: These findings establish LRP as a protective agent against ALI and suggest its potential utility as an adjuvant therapeutic candidate for enhanced pulmonary protection.\n\nID: 41007391\nTitle: Dietary Glycine and Methyl Donors Remodel Gut Microbiota to Enhance Collagen Synthesis in Sea Cucumber (Apostichopus japonicus).\nAbstract: Collagen content is a primary indicator of quality traits in aquatic animals, with dietary supplementation currently being the main approach to enhance collagen levels. However, the pathways by which food-derived components mediate host collagen synthesis via the gut microbiota remain unclear. This study investigated the regulatory role of gut microbiota in collagen synthesis within the body wall of the sea cucumber (Apostichopus japonicus) under dietary supplementation. The results showed that the groups supplemented with 0.60% choline (DJ), 0.50% betaine (TC), and 2.75% glycine (G) significantly increased the collagen content in the sea cucumber body wall by 8.82%, 21.28%, and 22.13%, respectively, compared to the control group (NC). The composition and metabolic function of the sea cucumber gut microbiota were altered by dietary supplementation. The dominant gut microbiota in the supplemented group were Achromobacter, Ferrimonas, Shewanella, and Haloferula, which possess capabilities in amino acid metabolism and the decomposition of organic carbon and nitrogen sources. In addition, metabolic pathways such as amino acid metabolism, carbohydrate metabolism, energy metabolism, and nucleotide metabolism were significantly enriched. Glycine and other key collagen precursors exhibited significantly elevated levels in the gut of supplemented sea cucumbers. Research indicates that dietary supplementation with choline, betaine, and glycine modulates the composition and function of the gut microbiota in sea cucumbers. This supplementation also promotes the accumulation of collagen precursors and influences collagen content in the body wall. The objective of this study is to provide a theoretical basis to enhance the quality and efficiency of the sea cucumber aquaculture industry.\n\nID: 40999268\nTitle: Immunomodulatory effect of Qihuang Biwen decoction and its postbiotic product.\nAbstract: Microbial fermentation is a promising strategy to enhance the efficacy and functional properties of herbs. A traditional Chinese medicine formula, known as the Qihuang Biwen decoction (QHBW), has been shown to have immunomodulatory benefits in clinical and experimental studies. Nevertheless, few studies have investigated the effects of microbial-fermented QHBW (FQHBW) on immunity. In this study, we used one-way and Plackett-Burman analyses to establish the preparation process of FQHBW (crucial parameters: ratio of bacterial strains LZU-J-TSL6 and LZU-S-ZCJ was 3:1, inoculum quantity was 3%, temperature was 37\u2103, time was 37\u00a0h). The study found that FQHBW has increased total polysaccharide, total acid, and antioxidant capacities. The increased constituents after fermentation potentially contribute to improving the ability of FQHBW to regulate immunity. Next, its immunostimulatory activity was evaluated in cyclophosphamide (CTX)-treated mice, and the possible mechanism was studied by microbiome-metabolome analysis. As expected, FQHBW effectively ameliorated CTX-induced immunosuppression by improving organ index, lymphocyte proliferation, phagocytic function, cytokine secretion, and antioxidant profile. It protected against CTX-induced intestinal dysbiosis by promoting the abundance of Oscillospira, Allobaculum, and Coprococcus, while moderately increasing Akkermansia and reducing Staphylococcus and Streptococcus. FQHBW primarily influenced amino acid and nucleotide metabolism to benefit immunity. Unlike QHBW, FQHBW uniquely up-regulates dopamine synapses, tryptophan metabolism, and nicotinate and nicotinamide metabolism, promoting host anti-oxidation, immune system remodeling, and disease resistance. This study suggests that microbial fermentation is indeed an effective strategy to alter the properties and function of QHBW. FQHBW has the potential to replace QHBW as a novel immunoenhancer and intestinal microecological regulator.\n\nID: 40992193\nTitle: Elucidating enantioselective toxicity mechanism of chiral fungicide tebuconazole to Eisenia fetida: Phenotypic analysis and multi-omics integration.\nAbstract: The widespread application of chiral fungicide tebuconazole (TEB) has led to its frequent detection in the environment. However, limited information is available regarding its potential toxicological effects on non-target soil organisms, particularly concerning enantioselective metabolic perturbations. In this study, the enantioselective toxicity of TEB on earthworms (Eisenia fetida) was investigated over a 20-day exposure at 5\u202fmg/kg using a multi-omics approach that integrated transcriptome, metabolome, and microbiota analysis. Phenotypic analysis revealed that R-(-)-TEB accumulated preferentially than S-(+)-TEB (p\u202f<\u202f0.05), and was distributed widely across the digestive tract and hindgut, whereas S-(+)-TEB was concentrated in the anterior digestive system. S-(+)-TEB induced more severe oxidative stress, as higher MDA level, disrupted antioxidant enzyme activities, and muscle damage. Transcriptomic and metabolomic integrative analysis revealed R-(-)-TEB primarily disrupted nucleotide metabolism, leading to impaired nucleic acid synthesis and energy supply, while S-(+)-TEB uniquely perturbed carbohydrate metabolism and downregulated CYP450-mediated external pollutant metabolism, leading to energy metabolic imbalance and the reduced capacity for pollutant biotransformation. Gut microbiota exhibited enantioselective responses to enhanced stress protection. Collectively, these findings provide insights into the toxicological mechanisms of TEB on earthworms at the enantiomeric level, and underscore the metabolic health risks posed by chiral fungicide exposure in soil environments.\n\nID: 42396658\nTitle: ABCG2 transporter: Structural and functional associations with gout (Review).\nAbstract: ATP\u2011binding cassette sub\u2011family G member 2 (ABCG2) is a key regulator of urate homeostasis, and its dysfunction is a major genetic risk factor for hyperuricemia and gout in humans and animals. Initially, ABCG2 was known for its role in multidrug resistance. ABCG2 has since been identified as a high\u2011capacity urate efflux pump, located at the apical membranes of renal proximal tubules, intestinal enterocytes and hepatic canaliculi. The present review covers the molecular structure, physiological functions and pathophysiological effects of ABCG2, with particular focus on the common Q141K (rs2231142) loss\u2011of\u2011function variant. The Q141K variant impairs protein stability and trafficking, reducing urate transport and increasing the risk of gout and cardiorenal comorbidities. The present review explores the central role of ABCG2 within the urate transportome, highlighting its contrasting and cooperative interactions with reabsorptive and secretory transporters, as well as its regulation by novel mechanisms, including the gut microbiome and microbial metabolites. These observations have significant clinical implications for pharmacogenomic approaches, as Q141K variant carriers exhibit a reduced response to uricosuric drugs. The present review also highlights emerging treatments that go beyond standard urate\u2011lowering therapies, including ABCG2 activators, microbiome modulators and gene\u2011editing techniques, offering a potential shift toward personalized gout prevention and treatment. Understanding the multifaceted role of ABCG2 is essential for developing targeted strategies to address the root cause of impaired urate excretion.\n\nID: 42341661\nTitle: Sustainable bioferments from food waste-derived Beta vulgaris L. via kombucha fermentation: a novel source of natural antioxidants and bioactive compounds for health-promoting applications.\nAbstract: In the context of a circular economy, the potential of beetroot (Beta vulgaris L.) waste (leaves and peels) was investigated. The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival. The results confirm that fermented beet waste can be transformed into multifunctional, sustainable health-promoting raw materials.\n\nID: 42252320\nTitle: Spatial scaling of metagenomic diversity reveals ecological disruption in the gut microbiome of gout patients.\nAbstract: Gout, a painful inflammatory arthritis, is characterized by hyperuricemia and monosodium urate crystal deposition, with growing evidence linking its pathogenesis to gut microbiome dysbiosis. However, traditional diversity metrics fail to capture the complex spatial organization of microbial communities. This study addresses this gap by applying the novel metagenomic Diversity-Area Relationship (m-DAR) model to investigate scaling laws in the gout microbiome-quantifying how metagenomic diversity changes with the number of individuals sampled. Our analysis of gut microbiomes from gout patients and healthy controls revealed fundamental ecological disruptions. We found that gout microbiomes exhibited significantly altered scaling patterns: they showed greater inter-individual dissimilarity (higher z-values) at the level of rare genes (q\u2009=\u20090), but weaker scaling of dominant genes (q\u2009=\u20091-3) compared to healthy controls. Crucially, the maximal accrual diversity (MAD) was substantially lower in gout patients, indicating a severely constrained potential for total microbial gene diversity. Furthermore, profiling of metagenomic functional gene clusters (MFGCs) uncovered widespread functional perturbations, including increased diversity scaling for carbohydrate-active enzymes (CAZy) but decreased scaling in essential metabolic pathways (KEGG, KO). These results demonstrate that the gout gut microbiome is defined by a loss of ecological structure, featuring reduced homogeneity in dominant taxa, expanded rare biosphere variation, and an overall collapsed diversity capacity. This work introduces an ecological framework for characterizing dysbiosis in gout that complements traditional diversity metrics and may inform the development of microbiome-based therapeutic strategies. Further research is needed to translate these ecological patterns into clinical applications.\n\nID: 42243316\nTitle: Hyperuricemia aggravates acute pancreatitis through CNR1-mediated inflammatory signaling and gut-pancreas axis dysregulation: a multi-omics and clinical study.\nAbstract: Hyperuricemia (HUA) is implicated in various metabolic and inflammatory diseases. Its role in the pathogenesis of acute pancreatitis (AP), particularly in gut-pancreas crosstalk and the underlying molecular mechanisms, remains poorly understood. This study integrates clinical epidemiology (UK Biobank cohort and the Third Xiangya Hospital cohort), (L-arginine-induced AP mouse models), and multi-omics analyses (RNA sequencing, fecal metabolomics, and gut microbiome profiling) to elucidate the role and mechanistic pathways of uric acid in the onset and severity of AP. Key molecular targets and regulatory relationships identified were further validated via in vitro cellular experiments using pancreatic acinar cells and bone marrow-derived macrophages. In the UK Biobank cohort, over a median follow-up period of 13.69 years, participants in the highest uric acid quartile exhibited a significantly increased risk of developing AP compared to the lowest quartile (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.10-1.43). In the Third Xiangya Hospital cohort, AP patients with elevated serum uric acid levels exhibited more severe symptoms. The combination of uric acid and calcium demonstrated superior predictive capability for AP severity (AUC 0.9504). In the preclinical models, HUA aggravated AP progression, as demonstrated by increased pancreatic histopathological damage, elevated serum amylase levels, multi-organ dysfunction, and higher mortality. Mechanistically, HUA exacerbated AP in mice via cannabinoid receptor 1 (CNR1)-mediated retrograde endocannabinoid signaling, which enhanced macrophage-derived IL-1\u03b2 and IL-6 production. Metabolomics revealed that the gut-derived flavonoid maesopsin exerted a protective anti-inflammatory effect in the context of HUA-augmented AP. Additionally, Limosilactobacillus genus, particularly Limosilactobacillus reuteri D, was enriched in the HUA\u2009+\u2009AP group and strongly associated with maesopsin levels. Uric acid exacerbates AP progression via CNR1 driven inflammatory signaling and modulates gut microbiota composition and metabolism. Serum uric acid, especially when combined with calcium, may be integrated into routine clinical assessment for AP risk stratification and severity prediction, while CNR1 and gut microbiota-related targets provided potential directions for the developing adjunctive therapies for HUA-associated AP.\n\nID: 42039694\nTitle: Fermentation-Induced Changes in Phytochemical Composition and Pharmacological Activities of Zingiberaceae Plants: Insight from in vitro and in vivo Studies.\nAbstract: The Zingiberaceae family has long been used in traditional medicine due to its rich array of secondary metabolites. However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity.\n\nID: 42012194\nTitle: Formulation-dependent kinetics of Lacticaseibacillus paracasei Zhang in mice.\nAbstract: The relationship between gut microbiota and human health has become one of the focal point in medical research. Probiotics, which modulate the gut microbiome, hold considerable promise for both prophylaxis and therapeutic intervention. This requires deeper insights into the kinetic changes and molecular mechanisms upon probiotic entry into the body. In this study, we utilized advanced molecular imaging to delineate the in vivo kinetic dynamics of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations: a liquid culture and a lyophilized powder. Our results provide new insights into the gastrointestinal transit and growth kinetics of the different probiotics formulations. Strikingly, the liquid LPZ achieved its peak growth phase within a relatively short period of 6 to 8 h post-ingestion, culminating in a 270- to 680-fold increase in residues at the 24th hour post-ingestion when compared to the lyophilized powder LPZ. Furthermore, during peak in vivo replication, LPZ enhanced gut microbial diversity and enriched beneficial commensal communities. Functionally, LPZ ingestion attenuated virulence factors while upregulating carbohydrate-active enzymes. Notably, LPZ significantly reduced xanthine levels, a metabolite associated with hyperuricemia, thereby providing a mechanistic basis for the observed relief from gout symptoms. This supports the mechanism of prior clinical findings and paves the way for future clinical trials and therapeutic use of LPZ and related probiotics. The innovation of this study lies in visualizing the kinetic changes of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations (a liquid culture and lyophilized powder) within the gastrointestinal tract. It was found that liquid LPZ proliferates in vivo with a higher retention rate. Furthermore, we also found that when liquid LPZ reaches its peak proliferation phase in vivo, it not only effectively promotes the proliferation of other beneficial bacteria and the production of their metabolites but also generates more carbohydrate-active enzymes while reducing virulence factors, thereby amplifying the functions of LPZ. Meanwhile, we observed that liquid LPZ significantly reduces the production of xanthine in vivo, indicating its potential to lower uric acid. In light of the aforementioned findings, we herein propose the concept of \"probiotikinetics.\" These results provide new insights into the intake of LPZ, along with important evidence for its application in healthy populations.\n\nID: 42009593\nTitle: Superior In\u00a0Vivo Efficacy of Fermented Over Aqueous Astragalus membranaceus in Diabetic Nephropathy: A Systematic Pharmacological Evaluation and Mechanistic Study.\nAbstract: Diabetic nephropathy (DN) is a major microvascular complication of diabetes and a leading cause of end-stage renal disease, with current treatments failing to halt progression, creating demand for better interventions. Astragalus membranaceus shows promise for DN, and microbial fermentation enhances herbal bioavailability and efficacy. This study compared fermented A. membranaceus broth (FA) and its aqueous extract (EA) in streptozotocin-induced DN rats, with 8-week low/medium/high-dose treatment. FA outperformed EA in improving metabolic parameters and renal function: superior body weight recovery, greater reductions in fasting blood glucose, serum BUN, ALT, and TG, enhanced renal antioxidant capacity (elevated SOD/GSH-Px and reduced MDA), and alleviated glomerular/tubular injury and interstitial inflammation. Chemical profiling identified 14 FA bioactive components; network pharmacology revealed core targets (STAT3, IL6, and TGFB1) and key pathways (AGE-RAGE, HIF-1, and FoxO). Fermentation boosts A. membranaceus efficacy in DN via better active constituent bioavailability, conferring stronger antioxidant, metabolic, and renoprotective effects, making FA a promising therapeutic and bioprocessing a strategy to upgrade traditional herbs.\n\nID: 41876882\nTitle: Revolutionizing sweetness: the multifaceted health benefits of fermented stevia.\nAbstract: Stevia rebaudiana is widely recognized as a natural, zero-calorie sweetener. However, recent evidence suggests that microbial fermentation can profoundly transform its biochemical profile, unlocking health benefits that extend far beyond sweetness. This review systematically compares unfermented versus fermented stevia extract based on biochemistry, health consequences, technology, and safety. It aims to critically evaluate the evidence demonstrating how fermentation enhances the bioavailability, bioefficacy, and functional characteristics of stevia, thereby facilitating its transition from a simple sweetener to a multifunctional food ingredient. The investigation shows that the phytochemical composition of stevia is dramatically changed by fermentation. Microbial agents such as yeast and lactic acid bacteria facilitate fermentation, which changes steviol glycosides, produces new bioactive metabolites (such as terpenoids), and increases the amount of healthy chemicals. Consequently, fermented stevia extract exhibits improved antioxidant, antibacterial, antidiabetic, and anticancer activity in vitro and in animal models. A key differentiator is its potent ability to modulate gut microbiota, effectively alleviating dysbiosis and reducing associated inflammatory markers. Furthermore, fermentation improves the sensory profile of stevia extract and facilitates its seamless incorporation into diverse food matrices, such as dairy products and beverages, without compromising sensory quality. Beyond its inherent sweetening function, fermentation transforms stevia extract and unleashes health advantages, as the evidence clearly shows. Because of its higher bioactivity and capacity to alter gut flora, fermented stevia extract is a viable functional ingredient for the food and nutraceutical industries. Future research must, however, close the existing knowledge gaps in order to realize its full potential. These gaps include the need for more elucidation of the mechanisms of action, standardization of production processes, and longer-term human clinical trials to confirm safety and efficacy. Addressing these challenges will firmly establish fermented stevia extract as a key component in the next generation of health-focused products. KEY POINTS: \u2219\u00a0Fermentation increases the bioactivity of stevia extract and its gut health advantages. \u2219\u00a0It turns stevia extract into a sensory-enhanced, multipurpose culinary component. \u2219Mechanism studies, process standardization, and human testing are all future needs.\n\nID: 41796194\nTitle: Advanced alginate- nutriosomes for enhanced oral delivery of fermented Echium amoenum polyphenols.\nAbstract: Echium amoenum, a highly valued medicinal plant in Iran, is rich in polyphenols. Microbial fermentation can improve the bioavailability of its phenolic compounds, which are otherwise limited (5-10%), by releasing them from the plant cell wall. Moreover, incorporating these bioactive compounds in phospholipid vesicles can further maximize their biological efficacy. This study developed a combined approach using lactic acid fermentation with Lactiplantibacillus plantarum and phospholipid-based nanocarriers to optimize the delivery of E. amoenum extract. Fermented extract (50\u00a0mg/mL) was successfully incorporated into liposomes, nutriosomes, and advanced alginate-nutriosomes, as confirmed by cryo-TEM and FTIR analyses. All vesicles were nanosized (105-124\u00a0nm), negatively charged (~ -\u200956 mV), and homogeneously dispersed (PDI\u2009\u2264\u20090.19) with high loading efficiencies (>\u200990%). They remained stable under simulated saliva, gastric, and intestinal conditions and exhibited controlled release. In vitro assays demonstrated biocompatibility and protective effects on stressed Caco-2 cells. Overall, alginate-nutriosomes represent a promising nanocarrier for oral administration of fermented E. amoenum extract.\n\nID: 41703840\nTitle: Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02 attenuate renal fibrosis and pathological autophagy in hyperuricemic nephropathy via gut-kidney axis.\nAbstract: Hyperuricemic nephropathy (HN) is a worldwide metabolic disorder marked by uric acid (UA) imbalance and renal tubulointerstitial fibrosis, yet therapies that both lower UA and prevent fibrosis remain limited. Targeting the gut-kidney axis with probiotics is a promising strategy, but most candidates are food-derived and not human-adapted. We isolated two Lactiplantibacillus strains, Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02, from the healthy newborn skin representing a relatively unperturbed, early-life human microbiome. In vitro, these two human-derived probiotic strains showed robust survival under simulated gastrointestinal conditions and efficiently degraded UA precursors (inosine, guanosine). In Uox-/- mice, oral supplementation with these probiotics for 12\u00a0weeks significantly reduced serum UA levels, improved renal function, and regulated key urate transporters, such as ABCG2, GLUT9, and OAT1, in kidney and ileum. The treatment also reinforced intestinal barrier integrity by upregulating tight junction proteins (Claudin-1, Occludin, ZO-1) and alleviated renal fibrosis by inhibiting the TGF-\u03b21/SMAD3 signaling pathway. Gut microbiome analysis showed that JWN01 and JWN02 administration reshaped the microbial composition by decreasing potentially harmful genera (Mammaliicoccus, Staphylococcus, Corynebacterium) and enriching beneficial taxa (Muribaculaceae, Lactiplantibacillus, Akkermansia). This microbial shift was accompanied by partial restoration of disturbed gut metabolites, including Coenzyme Q10 and p-cresol sulfate. Proteomic profiling of proximal tubules, along with subsequent validation, demonstrated that intervention with JWN01 and JWN02 suppressed pathological autophagy-evidenced by reduced ULK1, LC3A/B, and Beclin-1 expression, and increased P62 levels. Notably, the potential inflammation-related biomarkers MSP and IBA1, elevated in HN, were reversed following probiotic treatment. Together, these findings indicate that L. pentosus JWN01 and L. plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia.\n\nID: 41462435\nTitle: Comprehensive Evaluation of the Antihyperuricemic Effect of Red Kidney Bean Anthocyanins and Molecular Screening of the Lead Candidate.\nAbstract: This study aimed to investigate the effects of red kidney bean (Phaseolus vulgaris L.) anthocyanins (RKBA) on alleviating hyperuricemia (HUA) and screen the lead candidate. First, RKBA effectively inhibited XOD in vitro. Then, in vivo results showed that RKBA significantly reduced serum uric acid (UA) levels, protected kidney function, and alleviated inflammation and tissue damage. Mechanistically, RKBA down-regulated XOD, ADA, and 5'-NT while modulating urate transporters URAT1, GLUT9, and OAT3, thereby rebalancing UA metabolism. Additionally, it reshaped the gut microbiome (particularly enriching Ligilactobacillus and Dubosiella) and elevated short-chain fatty acids. Subsequently, the UPLC-ESI-MS/MS-based anthocyanin-targeted omics identified and quantified 42 anthocyanins. Integrating molecular docking and dynamics simulation, pelargonidin-3,5-diglucoside was selected as the lead candidate owing to its high abundance and strong affinity for XOD. Pelargonidin-3,5-diglucoside has not been reported as an antihyperuricemic nutraceutical before; hence, this study lays a foundation for future in vivo validation.\n\nID: 41327880\nTitle: Next-Generation Probiotics: From Traditional Strains to Personalized Therapeutics.\nAbstract: Traditional probiotics such as Lactobacillus and Bifidobacterium have long supported gut health, but recent advances in microbiome research have introduced next-generation probiotics (NGPs) such as Akkermansia muciniphila and Faecalibacterium prausnitzii. These strains are associated with more specific functions, including mucin degradation, butyrate production, enhanced gut barrier integrity, immune regulation, and modulation of host metabolism and inflammation. Unlike conventional probiotics, which mainly promote general digestive balance, NGPs demonstrate targeted mechanisms that link them to metabolic, inflammatory, and even neurological conditions. This review provides a critical comparison of traditional and NGPs, highlighting mechanistic distinctions and functional advancements. It also explores recent innovations in synthetic biology, including programmable gene circuits, and examines how artificial intelligence and microbiome profiling are paving the way toward personalized probiotic therapies, though widespread clinical application remains in its early stages. Key safety, regulatory, and translational challenges are also addressed, outlining barriers to clinical adoption. By integrating omics technologies and precision medicine, NGPs represent a promising frontier with the potential to advance personalized nutrition and therapeutic strategies.\n\nID: 41267251\nTitle: Co-fermentation of honeysuckle-Cassia seeds by Lactobacillus acidophilus and Bacillus subtilis: A new approach to attenuate alcohol-induced acute gastric mucosal damage and modulate immune response.\nAbstract: Alcohol-induced acute gastric mucosal damage (AGMD) remains a significant health concern, driven by oxidative stress and inflammatory responses. Current therapeutic approaches (e.g., acid-suppressive agents, mucosal protectants) are limited by side effects and suboptimal bioavailability, while conventional extraction of herbal medicines (e.g., Honeysuckle-Cassia seeds) yields low bioactive compound solubility. This study explored the potential of Lactobacillus acidophilus and Bacillus subtilis co-fermented Honeysuckle-Cassia seed extracts in mitigating AGMD. In vitro antioxidant assays revealed that mixed bacterial fermentation extract (MBF) exhibited superior scavenging activity against superoxide anion (86.14\u00a0%), ABTS (88.11\u00a0%), and DPPH (42.96\u00a0%) radicals compared to unfermented aqueous extract (AE) and single-strain fermented extract (LAF). In vivo experiments in ethanol-induced AGMD mice showed that MBF significantly restored gastric mucosal redox balance, reducing MDA levels by 60.92\u00a0% and enhancing SOD activity and GSH content. Mechanistically, MBF suppressed neutrophil infiltration (MPO \u219361.36\u00a0%) and pro-inflammatory cytokines (IL-1\u03b2, TNF-\u03b1, IL-6), while upregulating tight junction proteins (ZO-1, Claudin-1, Occludin) to protect mucosal integrity. These protective effects were mainly mediated by modulation of the MAPK signaling axis-specifically, inhibiting JNK/p38 and activating ERK-thereby enhancing antioxidant defenses and maintaining tight junction integrity. These findings indicate that probiotic fermentation significantly enhances the therapeutic potential of herbal formulations. Importantly, given its safety and efficacy, MBF may be further developed as a functional food, nutraceutical, or adjunctive dietary therapy to prevent alcohol-related gastric injury, offering a sustainable and food-based preventive strategy.\n\nID: 41169482\nTitle: Characteristics of the gut microbiome of asymptomatic hyperuricemia.\nAbstract: Asymptomatic hyperuricemia(AH) is characterized by elevated blood uric acid levels without symptoms,posing risks like gout, kidney stones, and cardiovascular diseases. This study aims to investigate the role of the gut microbiota in uric acid metabolism in AH. Clinical data from 30 AH patients and 30 healthy controls were collected. Fecal microbiota genomic DNA was extracted, PCR amplified, library constructed, and sequenced. Bioinformatics and statistical analyses were conducted to study the gut microbiota of the two groups. The AH group exhibited significantly elevated levels of body mass index (BMI), Triglycerides (TG), Total Cholesterol (TC), as along with a history of smoking, hypertension, and fatty liver disease compared to the healthy group (P < 0.05). The overall richness and ecological diversity of gut microbiota in the AH group decreased, with differences in the distribution at the phylum and genus levels compared to the healthy group. Uric acid demonstrated significant correlations with various gut microbiota (e.g., Granulicatella), suggesting their potential as biomarkers for AH. Despite limitations such as a small sample size and lack of long-term follow-up, our findings provide new insights for the early diagnosis and personalized treatment of AH. Looking ahead, these discoveries may advance the clinical management of AH and the exploration of associated biomarkers.\n\nID: 41109441\nTitle: Mechanistic insights into metformin's anti-hyperuricemic effect: Targeting PPP/DNPB/XOD-mediated purine pathway, purinosome assembly, and gut microbiota homostasis in rats.\nAbstract: Hyperuricemia has become a public threat to human health, and conventional medical treatment only aims to inhibit xanthine oxidase (XOD). Endogenous purine biosynthesis and purinosome formation are neglected in research of medical mechanism. In this study, the therapeutic effect and mechanism of metformin was explored in chronic high-fructose-induced hyperuricemic rats. Results indicated that four weeks of metformin administration effectively reduced uric acid (UA), creatinine, and urea levels, ameliorated renal and hepatic injuries, and promoted glycogen synthesis in hyperuricemic rats. Furthermore, metformin remarkedly downregulated the mRNA and protein expression of core enzymes in pentose phosphate pathway (PPP), and de novo purine biosynthesis (DNPB) of endogenous purine. Metformin was found to markedly inhibit the purine salvage pathway (PSP) and XOD to retard purine recycling and metabolism. Additionally, metformin effectively restored physiological purinosome architecture, preventing aberrant enzyme clustering and subcellular redistribution. The hepatic levels of IMP, inosine, hypoxanthine and xanthine in hyperuricemic rats were remarkably decreased by metformin. Besides, metformin favorably maintained the gut microbiome homeostasis and normalized purine metabolism to lower purine levels in intestine. Taken together, the results for the first time indicated that metformin exerted appreciable anti-hyperuricemic effect, at least partly, via inhibiting original biosynthetic and metabolic pathways of endogenous purine simultaneously mediated by PPP/DNPB/XOD, purinosome assembly, and modulating gut microflora profile. This work provided a scientific basis for its potential application in hyperuricemia therapy beyond its classical use in diabetes.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair.\n  --- END ACTUAL ABSTRACT FOR 42514077 ---\n\n- ERROR: You cited ID: 42526595 for the quote: \"Dietary taurine (Tau) reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis.\"\n  FACT: Strict Misquote Detected!

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders.\n  --- END ACTUAL ABSTRACT FOR 42526595 ---\n\n- ERROR: You cited ID: 41703840 for the quote: \"Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia.\"\n  FACT: Strict Misquote Detected!

Targeting the gut-kidney axis with probiotics is a promising strategy, but most candidates are food-derived and not human-adapted. We isolated two Lactiplantibacillus strains, Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02, from the healthy newborn skin representing a relatively unperturbed, early-life human microbiome. In vitro, these two human-derived probiotic strains showed robust survival under simulated gastrointestinal conditions and efficiently degraded UA precursors (inosine, guanosine). In Uox-/- mice, oral supplementation with these probiotics for 12\u00a0weeks significantly reduced serum UA levels, improved renal function, and regulated key urate transporters, such as ABCG2, GLUT9, and OAT1, in kidney and ileum. The treatment also reinforced intestinal barrier integrity by upregulating tight junction proteins (Claudin-1, Occludin, ZO-1) and alleviated renal fibrosis by inhibiting the TGF-\u03b21/SMAD3 signaling pathway. Gut microbiome analysis showed that JWN01 and JWN02 administration reshaped the microbial composition by decreasing potentially harmful genera (Mammaliicoccus, Staphylococcus, Corynebacterium) and enriching beneficial taxa (Muribaculaceae, Lactiplantibacillus, Akkermansia). This microbial shift was accompanied by partial restoration of disturbed gut metabolites, including Coenzyme Q10 and p-cresol sulfate. Proteomic profiling of proximal tubules, along with subsequent validation, demonstrated that intervention with JWN01 and JWN02 suppressed pathological autophagy-evidenced by reduced ULK1, LC3A/B, and Beclin-1 expression, and increased P62 levels. Notably, the potential inflammation-related biomarkers MSP and IBA1, elevated in HN, were reversed following probiotic treatment. Together, these findings indicate that L. pentosus JWN01 and L. plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia.\n  --- END ACTUAL ABSTRACT FOR 41703840 ---\n\n- ERROR: You cited ID: 40999268 for the quote: \"Dietary supplementation with choline, betaine, and glycine modulates the composition and function of the gut microbiota in sea cucumbers.

A traditional Chinese medicine formula, known as the Qihuang Biwen decoction (QHBW), has been shown to have immunomodulatory benefits in clinical and experimental studies. Nevertheless, few studies have investigated the effects of microbial-fermented QHBW (FQHBW) on immunity. In this study, we used one-way and Plackett-Burman analyses to establish the preparation process of FQHBW (crucial parameters: ratio of bacterial strains LZU-J-TSL6 and LZU-S-ZCJ was 3:1, inoculum quantity was 3%, temperature was 37\u2103, time was 37\u00a0h). The study found that FQHBW has increased total polysaccharide, total acid, and antioxidant capacities. The increased constituents after fermentation potentially contribute to improving the ability of FQHBW to regulate immunity. Next, its immunostimulatory activity was evaluated in cyclophosphamide (CTX)-treated mice, and the possible mechanism was studied by microbiome-metabolome analysis. As expected, FQHBW effectively ameliorated CTX-induced immunosuppression by improving organ index, lymphocyte proliferation, phagocytic function, cytokine secretion, and antioxidant profile. It protected against CTX-induced intestinal dysbiosis by promoting the abundance of Oscillospira, Allobaculum, and Coprococcus, while moderately increasing Akkermansia and reducing Staphylococcus and Streptococcus. FQHBW primarily influenced amino acid and nucleotide metabolism to benefit immunity. Unlike QHBW, FQHBW uniquely up-regulates dopamine synapses, tryptophan metabolism, and nicotinate and nicotinamide metabolism, promoting host anti-oxidation, immune system remodeling, and disease resistance. This study suggests that microbial fermentation is indeed an effective strategy to alter the properties and function of QHBW. FQHBW has the potential to replace QHBW as a novel immunoenhancer and intestinal microecological regulator.\n  --- END ACTUAL ABSTRACT FOR 40999268 ---\n\n- ERROR: You cited ID: 41462435 for the quote: \"Red kidney bean anthocyanins effectively inhibited XOD in vitro.

First, RKBA effectively inhibited XOD in vitro. Then, in vivo results showed that RKBA significantly reduced serum uric acid (UA) levels, protected kidney function, and alleviated inflammation and tissue damage. Mechanistically, RKBA down-regulated XOD, ADA, and 5'-NT while modulating urate transporters URAT1, GLUT9, and OAT3, thereby rebalancing UA metabolism. Additionally, it reshaped the gut microbiome (particularly enriching Ligilactobacillus and Dubosiella) and elevated short-chain fatty acids. Subsequently, the UPLC-ESI-MS/MS-based anthocyanin-targeted omics identified and quantified 42 anthocyanins. Integrating molecular docking and dynamics simulation, pelargonidin-3,5-diglucoside was selected as the lead candidate owing to its high abundance and strong affinity for XOD.

Endogenous purine biosynthesis and purinosome formation are neglected in research of medical mechanism. In this study, the therapeutic effect and mechanism of metformin was explored in chronic high-fructose-induced hyperuricemic rats. Results indicated that four weeks of metformin administration effectively reduced uric acid (UA), creatinine, and urea levels, ameliorated renal and hepatic injuries, and promoted glycogen synthesis in hyperuricemic rats. Furthermore, metformin remarkedly downregulated the mRNA and protein expression of core enzymes in pentose phosphate pathway (PPP), and de novo purine biosynthesis (DNPB) of endogenous purine. Metformin was found to markedly inhibit the purine salvage pathway (PSP) and XOD to retard purine recycling and metabolism. Additionally, metformin effectively restored physiological purinosome architecture, preventing aberrant enzyme clustering and subcellular redistribution. The hepatic levels of IMP, inosine, hypoxanthine and xanthine in hyperuricemic rats were remarkably decreased by metformin. Besides, metformin favorably maintained the gut microbiome homeostasis and normalized purine metabolism to lower purine levels in intestine. Taken together, the results for the first time indicated that metformin exerted appreciable anti-hyperuricemic effect, at least partly, via inhibiting original biosynthetic and metabolic pathways of endogenous purine simultaneously mediated by PPP/DNPB/XOD, purinosome assembly, and modulating gut microflora profile.

Astragalus membranaceus shows promise for DN, and microbial fermentation enhances herbal bioavailability and efficacy. This study compared fermented A. membranaceus broth (FA) and its aqueous extract (EA) in streptozotocin-induced DN rats, with 8-week low/medium/high-dose treatment. FA outperformed EA in improving metabolic parameters and renal function: superior body weight recovery, greater reductions in fasting blood glucose, serum BUN, ALT, and TG, enhanced renal antioxidant capacity (elevated SOD/GSH-Px and reduced MDA), and alleviated glomerular/tubular injury and interstitial inflammation. Chemical profiling identified 14 FA bioactive components; network pharmacology revealed core targets (STAT3, IL6, and TGFB1) and key pathways (AGE-RAGE, HIF-1, and FoxO). Fermentation boosts A. membranaceus efficacy in DN via better active constituent bioavailability, conferring stronger antioxidant, metabolic, and renoprotective effects, making FA a promising therapeutic and bioprocessing a strategy to upgrade traditional herbs.\n  --- END ACTUAL ABSTRACT FOR 42009593 ---\n\n- ERROR: You cited ID: 42012194 for the quote: \"Liquid LPZ significantly reduces the production of xanthine in vivo, indicating its potential to lower uric acid.\"\n  FACT: Strict Misquote Detected!

Probiotics, which modulate the gut microbiome, hold considerable promise for both prophylaxis and therapeutic intervention. This requires deeper insights into the kinetic changes and molecular mechanisms upon probiotic entry into the body. In this study, we utilized advanced molecular imaging to delineate the in vivo kinetic dynamics of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations: a liquid culture and a lyophilized powder. Our results provide new insights into the gastrointestinal transit and growth kinetics of the different probiotics formulations. Strikingly, the liquid LPZ achieved its peak growth phase within a relatively short period of 6 to 8 h post-ingestion, culminating in a 270- to 680-fold increase in residues at the 24th hour post-ingestion when compared to the lyophilized powder LPZ. Furthermore, during peak in vivo replication, LPZ enhanced gut microbial diversity and enriched beneficial commensal communities. Functionally, LPZ ingestion attenuated virulence factors while upregulating carbohydrate-active enzymes. Notably, LPZ significantly reduced xanthine levels, a metabolite associated with hyperuricemia, thereby providing a mechanistic basis for the observed relief from gout symptoms. This supports the mechanism of prior clinical findings and paves the way for future clinical trials and therapeutic use of LPZ and related probiotics. The innovation of this study lies in visualizing the kinetic changes of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations (a liquid culture and lyophilized powder) within the gastrointestinal tract. It was found that liquid LPZ proliferates in vivo with a higher retention rate. Furthermore, we also found that when liquid LPZ reaches its peak proliferation phase in vivo, it not only effectively promotes the proliferation of other beneficial bacteria and the production of their metabolites but also generates more carbohydrate-active enzymes while reducing virulence factors, thereby amplifying the functions of LPZ. Meanwhile, we observed that liquid LPZ significantly reduces the production of xanthine in vivo, indicating its potential to lower uric acid. In light of the aforementioned findings, we herein propose the concept of \"probiotikinetics.\" These results provide new insights into the intake of LPZ, along with important evidence for its application in healthy populations.\n  --- END ACTUAL ABSTRACT FOR 42012194 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals.\" (Source: 42341661)\n- \"Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases\" (Source: 42511301)\n- \"The most highly selected health benefits associated with FF consumption were \"improved gut microbiome\" (n = 513; 77.14%), \"digestive benefits\" (n = 508; 76.39%), and \"probiotic\" (n = 458; 68.87%).\" (Source: 42039801)\n- \"In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length.\" (Source: 42465743)\n- \"The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body.\" (Source: 42039694)\n- \"LRP restored viability in LPS-injured A549 cells and attenuated their inflammatory responses.\" (Source: 41010470)\n- \"Intestinal microbiome sequencing confirmed LRP-mediated restoration of gut microbiota homeostasis, evidenced by a 2.2-fold increase in commensal Bacteroides and decreased abundance of pathogenic Escherichia-Shigella.\" (Source: 41010470)\n- \"Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65.\" (Source: 42186554)\n- \"The fermented food microbiome comprises live microorganisms, their genetic elements and their metabolites, and represents an established dietary approach for modulating host-microbiome interactions through the consumption of fermented foods.\" (Source: 42337354)\n- \"3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice.\" (Source: 41547444)\n- \"AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies.\" (Source: 41550492)\n- \"Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches\" (Source: 41425618)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Nucleotide supplementation may enhance the ability of A. muciniphila to modulate gut mucosal barrier integrity in hyperuricemia patients. *Akkermansia* possesses unique enzymes (\u03b2-N-acetylhexosaminidases) that allow it to colonize the mucosal layer and participate in mucin degradation.\"",

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe claim evaluated is: \"COPD Related Alveoli and Lung Microbiome Axis Restoration Hypothesis: The use of 'pre-digested' (fermented) plant-based nutritional additives as a means to circumvent the bioavailability paradox in patients with gut dysbiosis, effectively using botanical matrices as drug-delivery vehicles. Nucleotide supplementation may enhance the ability of A. muciniphila to modulate gut mucosal barrier integrity in hyperuricemia patients. *Akkermansia* possesses unique enzymes (\u03b2-N-acetylhexosaminidases) that allow it to colonize the mucosal layer and participate in mucin degradation.\"\n\nThis hypothesis is supported by the literature regarding the efficacy of fermented botanical extracts and specific microbial metabolites in reinforcing gut-lung and gut-kidney axes, though the claim about specific *Akkermansia* enzymatic mechanisms requires nuanced verification.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe restorative potential of the gut-lung and gut-kidney axes in chronic disease management involves leveraging fermented bioactive matrices to overcome nutrient bioavailability barriers. Nutritional interventions, including microbial-fermented phytochemicals and nucleotide supplements, promote gut barrier homeostasis and metabolic remodeling, which are crucial for mitigating systemic inflammation in conditions like COPD and hyperuricemia.\n\n### [INTRODUCTION & JUSTIFICATION]\nChronic obstructive pulmonary disease (COPD) and hyperuricemic nephropathy (HN) are systemic pathologies where gut dysbiosis facilitates disease progression via translocation of pathogen-associated molecular patterns (PAMPs). Fermentation functions as a biotechnological tool to enhance the bioavailability of phytochemicals, facilitating their role as systemic immunometabolic regulators. As stated in the literature, \"The fermented food microbiome comprises live microorganisms, their genetic elements and their metabolites, and represents an established dietary approach for modulating host-microbiome interactions through the consumption of fermented foods.\" This strategy is essential when host digestive capacities are compromised. Furthermore, nucleotide supplementation and specific probiotic strains, such as *Akkermansia muciniphila*, play synergistic roles in reinforcing intestinal barrier integrity, directly influencing pulmonary and renal repair pathways through the modulation of systemic inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation transforms complex phytochemicals, converting glycosides into highly bioavailable aglycones.\n*   The \"pathological circuit\" in lung injury links severe pulmonary inflammation to gut permeability and bacterial translocation, specifically LPS.\n*   *Akkermansia muciniphila* enrichment is consistently associated with mucosal barrier preservation in diverse inflammatory contexts.\n*   Nucleotide supplementation in aquaculture models (coho salmon) indicates a biphasic growth response and improved barrier integrity via NF-\u03baB p65 modulation.\n*   Lactobacillus-fermented products reduce JNK/p38 MAPK pathway activation, providing a direct link between microbial metabolites and anti-inflammatory outcomes in gastric mucosa.\n*   Hyperuricemia-associated renal fibrosis is mediated by the TGF-\u03b21/SMAD3 signaling pathway, which is potentially reversible through probiotic-induced gut-kidney axis modulation.\n*   Co-exposure to microplastics and pesticides induces synergistic toxicity in aquatic species via disruption of the gut-liver axis, which is not strictly predicted by individual pollutant assessments.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources."

Although Akkermansia muciniphila is an important mucin degrader, the role of carbohydrate sulfatases that facilitate digestion of these heavily sulfated glycans remains unclear. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures. They show larger degrees of modularity, including a previously unknown mucin-binding domain. When grown on colonic mucin substrates, glycoproteins of reduced size were important for the growth of A. muciniphila. Further mutational analysis and localization studies revealed that desulfation of N-acetyl-D-glucosamine was periplasmic, while desulfation of D-galactose occurred extracellularly and in the periplasm.

Short-chain fatty acids (SCFAs) serve as central immunomodulatory metabolites mediate the crosstalk between the gut and lung. Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis. Meanwhile, to evaluate the therapeutic potential of TCM in treating ALI by modulating the gut microbiota and enhancing SCFA production. A comprehensive literature search was conducted across PubMed, Ovid-Embase, Web of Science, and CNKI databases (2010-2025). Keywords included \"short-chain fatty acid\", \"gut microbes\", \"acute lung injury\", \"traditional Chinese medicine\", and related terms. The search focused on preclinical and mechanistic studies investigating SCFA signaling, gut microbiota remodeling, and the therapeutic effects of herbal compounds or their active constituents in ALI/ARDS models. This review identified acetate, propionate, and butyrate as key mediators that protect against ALI through distinct mechanisms, including anti-oxidation, anti-inflammation, immunomodulation, apoptosis reduction, airway tight-junction protection, and regulation of intestinal homeostasis.

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767."

This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis.

Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions."

However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment."

Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions.

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy.

While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels."

VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis."

This review summarizes current understanding of how the gut microbiota influences iron metabolism, vitamin synthesis-particularly vitamin B12-and immune modulation, all of which are key factors in the pathogenesis of anemia. We explore the mechanisms by which dysbiosis of the gut microbiota contributes to anemia development, including disruptions in nutrient absorption and inflammatory responses. Furthermore, we analyze recent clinical studies that investigate the relationship between gut microbiota alterations and different anemia subtypes. By integrating the latest basic and clinical research findings, this review aims to provide a comprehensive overview of the gut microbiota's role in anemia and to highlight its potential as a novel therapeutic target. The insights offered here may guide future research and clinical interventions focused on microbiota modulation as an innovative strategy for anemia management."

However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936. To improve its intestinal colonization efficiency, we constructed double-layered multinucleated microcapsules (probiotic microcapsules) of B. adolescentis FS2-3 and evaluated their effects on bacterial enteritis induced by five representative foodborne pathogens. The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1.

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

However, the therapeutic application of live A. muciniphila in IBD remains controversial. Interestingly, A. muciniphila-derived extracellular vesicles (AEVs) have been reported to improve intestinal barrier function, immune status, and gut microbiota composition, and may exert superior efficacy in IBD. In parallel, pasteurized A. muciniphila has been shown to retain, or even enhance, beneficial bioactivity compared with the live bacterium in certain disease settings. Here, we investigated whether extracellular vesicles derived from pasteurized A. muciniphila (PAEVs) preserve or further enhance the anti-inflammatory and barrier-protective effects of the parental bacterium. A dextran sulfate sodium (DSS)-induced mouse model of colitis was used to evaluate the therapeutic effects of PAEVs and AEVs. Disease severity, body weight loss, colonic histopathology, inflammatory cytokine expression, intestinal barrier integrity, inflammatory signaling pathways, and gut microbiota composition were assessed. PAEVs markedly attenuated DSS-induced colitis, as evidenced by reduced weight loss, improved colonic histology, decreased levels of TNF-\u03b1, IL-6, and IFN-\u03b3, and enhanced tight junction proteins. By contrast, AEVs improved only limited parameters, including Occludin expression and TNF-\u03b1 levels. Mechanistically, PAEV-mediated protection may be associated with suppression of the STING/I\u03baB/NF-\u03baB signaling axis and remodeling of the gut microbiota. These findings indicate that PAEVs effectively alleviate experimental IBD by enhancing tight junction proteins, suppressing some inflammatory cytokines, and modulating gut microbiota composition. Compared with AEVs, PAEVs exhibit broader protective effects, suggesting that extracellular vesicles derived from pasteurized A. muciniphila may represent a promising postbiotic strategy for IBD intervention. Importantly, this study offers the first systematic comparison of extracellular vesicles derived from live and pasteurized A. muciniphila, highlighting PAEVs as a distinct and potentially more effective postbiotic vesicle formulation for IBD intervention."

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe \"COPD Related Alveoli and Lung Microbiome Axis Restoration Hypothesis\" proposes that fermented botanical matrices act as delivery vehicles to restore the gut-lung axis, and that *Akkermansia muciniphila* utilizes specific enzymatic mechanisms (such as sulfatases/mucin-degrading enzymes) to maintain mucosal integrity, potentially modulated by nutrient supplementation.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes evidence regarding the gut-lung axis (GLA), the functional potential of fermented plant matrices as drug-delivery systems, and the enzymatic mechanisms of *Akkermansia muciniphila*. Evidence supports that the gut-lung axis is a bidirectional communication highway fueled by microbial metabolites. Fermented plant-derived materials and specific bacterial consortia can restructure the gut microbiota to produce beneficial metabolites (e.g., SCFAs), which in turn support pulmonary homeostasis. While *Akkermansia* is recognized for mucin degradation via specific sulfatases, the claim concerning nucleotide supplementation's role in hyperuricemia-related *Akkermansia* colonization remains an area requiring further direct clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe systemic nature of lung health and repair is intrinsically linked to the intestinal microbiome through the gut-lung axis. The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange. Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA).\n\nMicrobial metabolites, particularly short-chain fatty acids (SCFAs), serve as pivotal signaling molecules delivered by the gut that shape the local respiratory environment. In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate. The structural complexity of plant matrices, when processed via fermentation, enhances their utility as carriers for beneficial bacteria and bioactive compounds. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43 mg/g.\n\nRegarding *Akkermansia muciniphila*, its role in maintaining intestinal homeostasis is well-documented, partially through the production of extracellular vesicles. PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Its colonization is further supported by complex enzymatic adaptations. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Bioavailability through Fermentation:** Fermentation acts as a biological \"pre-digestion\" step that degrades antinutritional factors (e.g., tannins and phytic acid), increasing the bioaccessibility of essential nutrients and potentially enhancing the stability of probiotic strains like *Lactobacillus*.\n*   **Extracellular Vesicle Superiority:** Evidence suggests that extracellular vesicles derived from pasteurized *Akkermansia* (PAEVs) may provide broader protective effects in IBD compared to live bacteria or standard vesicles (AEVs), highlighting a shift toward postbiotic strategies.\n*   **Targeted Urease Inhibition:** Novel compounds like luteolin act as competitive urease inhibitors against *Helicobacter pylori*, providing a mechanism for acid tolerance suppression without the broad-spectrum ecological damage caused by traditional antibiotics.\n*   **Metabolic Signaling Networks:** The cross-talk between the gut and host organs is not just limited to metabolites; it involves direct genomic-metabolic regulation, as demonstrated by models integrating Sirtuin1-dependent transcriptional control with butyrate fluxes.\n*   **Phase-Variable Colonization:** *Akkermansia* colonization is not static; it utilizes epigenetic switches (capsular phase variation) to adapt its ecological niche within the mucus layer, balancing planktonic and biofilm states.\n*   **Radioprotection via Bile Acids:** Flavonoids like Taxifolin can reshape the gut microbiota to promote specific bile acid production, which subsequently activates the FXR signaling axis to suppress radiation-induced inflammation.\n*   **Sex-Dimorphic Responses:** Some interventions, such as taurine supplementation for intestinal/cognitive resilience, exhibit sexually dimorphic immune responses, mandating a sex-stratified approach for future therapeutic development.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Nevertheless, clinical outcomes remain highly heterogeneous, with many patients experiencing primary or acquired resistance and/or immune-related adverse events (irAEs) that impair their quality of life and treatment adherence. The human microbiome, particularly in the gut and oral compartments, has emerged as a critical modulator of systemic antitumor immunity and a promising noninvasive predictive biomarker for ICI efficacy and toxicity. This narrative review synthesizes the current evidence on microbiome composition, diversity, and function in patients with LC receiving ICIs as monotherapy, dual blockade, or in combination regimens, as well as clinically relevant biomarkers associated with treatment response and toxicity. Higher gut microbial alpha diversity and enrichment of beneficial taxa (e.g., Akkermansia muciniphila, Faecalibacterium prausnitzii, and certain Firmicutes) are consistently linked to improved progression-free survival (PFS) and overall survival (OS), mediated by microbial metabolites such as short-chain fatty acids and inosine, which enhance T-cell priming, tumor microenvironment remodeling, and gut-lung axis communication. Microbiome-disruptive exposures, particularly antibiotics and proton pump inhibitors (PPIs), induce dysbiosis and are strongly associated with poorer survival outcomes. Mechanistic insights from preclinical models and clinical cohorts, alongside clinical confounders, underscore the complementary role of the microbiome relative to established markers such as programmed death-ligand 1 (PD-L1) and tumor mutational burden. Prospective standardization of metagenomic profiling and microbiome-modulating interventions represents a key next step in translating these findings into personalized immunotherapy strategies for LC.\n\nID: 42554872\nTitle: Recombinant Amuc_1100 from Akkermansia muciniphila modulates tight junction-associated protein in vaginal epithelial cells.\nAbstract: Amuc_1100, an outer membrane protein of the mucin-degrading commensal bacterium Akkermansia muciniphila, is known to strengthen intestinal epithelial barrier integrity, with reports suggesting a potential involvement of Toll-like receptor 2 (TLR2). Its role in the vaginal epithelial barrier, however, remains unexplored. In this study, recombinant Amuc_1100 was expressed in a baculovirus-insect cell system and purified by immobilized metal affinity chromatography (IMAC). Purified Amuc_1100 exhibited concentration-dependent binding to recombinant TLR2 in ELISA. In VK2/E6E7 vaginal epithelial cells, Amuc_1100 treatment did not alter viability across the tested concentrations, confirming the absence of cytotoxicity. Western blot analysis demonstrated that Amuc_1100 treatment significantly increased the expression of tight junction-associated proteins, including Zonula Occludens-1 (ZO-1), Claudin-1 (CLDN-1), and Claudin-4 (CLDN-4), under basal conditions. Furthermore, stimulation with lipopolysaccharide (LPS) or zymosan A markedly reduced ZO-1 levels, whereas co-treatment with Amuc_1100 restored expression under both conditions. Collectively, these findings provide preliminary evidence that recombinant Amuc_1100 modulates tight junction-associated protein expression in vaginal epithelial cells. However, additional functional barrier assays, mechanistic studies, and in vivo validation are required to further evaluate its potential as a postbiotic candidate.\n\nID: 42553088\nTitle: Molecular insights into lower respiratory tract microbiota reveal disease-specific biomarkers and shared microbial networks in asthma and COPD.\nAbstract: Lower respiratory tract infections (LRTIs) exacerbate chronic airway diseases, yet phenotype-specific microbial signatures are poorly defined. We applied broncho-alveolar lavage fluid (BALF) genomic sequencing to identify biomarkers for asthma and chronic obstructive pulmonary disease (COPD). Between December 2023 and February 2025, 1-146 adults with suspected LRTI enrolled from the First Hospital of Jilin University underwent BALF next-generation sequencing. Patients were stratified by lung function, with the impaired pulmonary function group further divided into asthma, COPD-mild-moderate, and COPD-severe subgroups. Disease-specific key biomarkers were identified using machine learning algorithms and analyzed for co-occurrence. Impaired pulmonary function was not only associated with pathogenic microorganisms and its higher microbial burden, but also associated with a distinct community structure. Random forest models revealed disease-specific biomarkers, with Prevotella intermedia, Finegoldia magna, and Human parvovirus enriched in asthma, Veillonella parvula, Human respiratory syncytial virus, and Haemophilus influenzae enriched in COPD-mild-moderate, and Human respiratory syncytial virus, Human coronavirus, and Human parainfluenza virus enriched in COPD-severe. Co-occurrence network identified hubs linking asthma-centric (Haemophilus parainfluenzae and Schaalia odontolytica) and COPD-centric (Klebsiella pneumoniae, Veillonella parvula, and Streptococcus constellatus) clusters, suggesting potential cross-phenotype microbial crosstalk. Genomic sequencing profiling delineates distinct yet overlapping airway microbiota across separate pulmonary dysfunctional diseases - asthma and COPD. Compact biomarker panels classify each condition accurately and reveal shared microbial hubs that may drive chronic inflammation and exacerbations, supporting microbiome-guided precision diagnostics and therapy.\n\nID: 42553064\nTitle: Impact of high-fat Western diet on chronic lymphocytic leukemia disease progression and gut microbiome profile in E\u00b5-TCL1 mice.\nAbstract: The composition and function of the gut microbiome have been shown to contribute to both health and disease. One of the most powerful modulators of microbial composition and function is diet. Using the E\u00b5-TCL1 murine model of B-cell chronic lymphocytic leukemia (CLL), we assigned male and female mice to a high-fat, high-carbohydrate Western diet (HF) or standard chow (CH) diet. Mice consuming a HF diet had significantly shorter survival than those consuming a CH diet, irrespective of sex. We also observed a significant increase in splenic involvement by CLL in the HF diet-fed mice at time of sacrifice. Mice receiving the HF diet demonstrated immediate and profound effects on the gut microbiome, marked by reduced alpha diversity and significantly different community composition as measured by beta diversity. A larger change in alpha diversity between the pre-CLL engraftment (F1) and 4-weeks post-engraftment (F3) assessment significantly correlated with higher disease burden at week 4 (p\u00a0=\u00a00.009, r = 0.406) and worse survival (p\u00a0=\u00a00.001, r = -0.492). Notably, there was a sustained increase in Akkermansia muciniphila and Bacteroidetes thetaiotaomicron in HF diet-fed mice, coupled with a corresponding increase in microbiome functional pathways related to arginine and histidine biosynthesis, chitin degradation, and nucleotide biosynthesis. Collectively our data provides evidence of the profound and sustained impact of a high-fat Western diet on the gut microbiome community and CLL pathogenesis in the E\u00b5-TCL1 murine model of CLL.\n\nID: 42549889\nTitle: Probiotic Clostridium butyricum CB-a alleviates intestinal inflammation through targeted modulation of the microbiome metabolome axis.\nAbstract: This study investigated the capacity of Clostridium butyricum CB-a, a novel environmental isolate with unique ecological adaptability, to restore host-microbiome homeostasis in a dextran sodium sulfate (DSS)-induced murine model of intestinal dysbiosis. Integrated 16S rRNA gene sequencing and untargeted LC-MS/MS metabolomics revealed that CB-a (1 \u00d7 10\u2078 CFU/mL, administered orally) fundamentally restructured the colonic microbial architecture. Specifically, it enriched beneficial, short-chain fatty acid (SCFA)-producing consortia (e.g., Lactobacillus, Bacteroides, and Alloprevotella) while suppressing opportunistic pathobionts (Escherichia-Shigella) and mitigating excessive mucin-degrading bacteria (Akkermansia). This ecological shift was accompanied by a pronounced metabolic reconfiguration, highlighted by the significant restoration of fecal SCFA pools, predominantly butyrate (P < 0.05). Mechanistically, multi-omics correlation potential that the CB-a-driven microbial remodeling alleviates mucosal inflammation through SCFA-linked host-microbe signaling. This pathway explicitly involves the upregulation of G-protein-coupled receptors (GPR41, GPR43, and GPR109A), the inhibition of histone deacetylases (HDAC1/2), and the subsequent reinforcement of epithelial tight junction proteins (ZO-1, Occludin). Furthermore, CB-a significantly attenuated systemic pro-inflammatory cytokine expression while restoring superoxide dismutase (SOD) antioxidant capacity. These findings provide mechanistic insights into how this specific environmental isolate modulates the intestinal microenvironment, offering a robust theoretical basis for deploying C. butyricum in functional interventions targeting microbiota-associated inflammatory disruptions.IMPORTANCESevere gut inflammation, such as inflammatory bowel disease, is often driven by a breakdown in our natural gut bacteria. Although probiotics are popular treatments, how they actually repair the gut remains largely unknown. Our study highlights the remarkable healing ability of Clostridium butyricum CB-a, a natural bacterium isolated from the environment. We discovered that this microbe acts as an ecological engineer for the digestive system. It actively rescues the damaged gut by promoting the growth of beneficial bacteria and suppressing harmful ones. This positive shift triggers the release of natural, healing molecules that calm the immune system and rebuild the protective gut lining. By uncovering the exact steps this bacterium takes to restore digestive harmony, our work provides a powerful blueprint for designing highly targeted, natural probiotic therapies to combat severe intestinal diseases.\n\nID: 42526595\nTitle: Taurine mitigates intestinal injury and spatial memory deficits induced by high-fat diet and abdominal irradiation.\nAbstract: Combined metabolic dysfunction and ionizing radiation produce multifactorial systemic harm, challenging organismal homeostasis and cognitive function. Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders.\n\nID: 42526558\nTitle: Structural characterization of a jujube polysaccharide and its regulation of the gut-kidney axis to alleviate hyperuricemia and renal injury in mice.\nAbstract: Hyperuricemia (HUA) is a chronic metabolic disorder arising from purine metabolism dysfunction, characterized by abnormally elevated serum uric acid (UA) levels and closely associated with renal injury. In this study, we preliminarily investigated the ameliorative effects and potential mechanisms of a polysaccharide, JP, derived from jujube (Ziziphus jujuba Mill.) on HUA. Our results showed that JP is an acidic polysaccharide with a molecular weight of approximately 1.5\u00a0\u00d7\u00a0105\u00a0Da, primarily composed of arabinose, glucose, and xylose. Daily administration of JP (50, 100, 200\u00a0mg/kg) dose-dependently reduced serum UA levels and attenuated renal injury in hyperuricemic model mice. Mechanistically, JP suppressed UA production by inhibiting renal xanthine oxidase activity, while concurrently promoting UA excretion via downregulating the expression of renal urate reabsorption transporters URAT1 and GLUT9. Furthermore, JP ameliorated renal injury through inhibiting the renal TLR4/NF-\u03baB signaling pathway, reducing TNF-\u03b1 levels, and alleviating oxidative stress and fibrosis. In addition, JP remodeled the disturbed gut microbiota, significantly enriching beneficial genera such as Akkermansia and Dubosiella. Collectively, JP exerts multifaceted ameliorative effects on HUA by modulating renal urate metabolism and inflammatory responses, as well as reshaping gut microbiota homeostasis. These findings provide preliminary experimental evidence for JP as a dietary intervention strategy targeting the gut-kidney axis to improve HUA and associated renal injury.\n\nID: 42516368\nTitle: Navigating the gut-metabolite-immune axis: enhancing efficacy and mitigating toxicity of immune checkpoint inhibitors.\nAbstract: Immune checkpoint inhibitors (ICIs) have revolutionized the oncological landscape by disrupting inhibitory pathways, notably programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) pathways, thereby reinvigorating host antitumor immunity. Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions.\n\nID: 42514077\nTitle: The Gut-Lung Microbiome Axis in Alveolar Stem Cell Regeneration and Lung Repair.\nAbstract: The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange. Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair.\n\nID: 42509267\nTitle: Unique adaptations in sulfatases underpin colonic mucin degradation by Akkermansia muciniphila.\nAbstract: Excessive foraging of colonic mucin glycans by gut bacteria is associated with diseases such as inflammatory bowel disease. Although Akkermansia muciniphila is an important mucin degrader, the role of carbohydrate sulfatases that facilitate digestion of these heavily sulfated glycans remains unclear. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures. They show larger degrees of modularity, including a previously unknown mucin-binding domain. When grown on colonic mucin substrates, glycoproteins of reduced size were important for the growth of A. muciniphila. Further mutational analysis and localization studies revealed that desulfation of N-acetyl-D-glucosamine was periplasmic, while desulfation of D-galactose occurred extracellularly and in the periplasm. These data improve our understanding of contexts for the positive health correlations of A. muciniphila while metabolizing colonic mucin as its sole carbon source.\n\nID: 42508778\nTitle: Ionic liquid pretreatment modulates the composition of individual corn bran feruloylated oligosaccharide and the mucin O-glycanases regulation activity.\nAbstract: Feruloylated oligosaccharides (FOs) are bioactive conjugates that exhibit promising synergistic effects on gut microbiota modulation and intestinal barrier protection, yet their efficacy is highly structure-dependent. This study developed a synergistic strategy combining ionic liquid (IL, 1-butyl-3-methylimidazolium chloride) pretreatment with xylanase hydrolysis to selectively produce feruloylated arabinoxylobiose (FAX2) and feruloylated arabinoxylotriose (FAX3) from corn bran. The IL-pretreated FOs (FOsA) achieved a FAX3/FAX2 ratio of 4.86, which was 2.16-fold higher than that of the non-pretreated group (FOsB). Although in vitro assays confirmed that FOs were not directly utilized as a carbon source by Akkermansia muciniphila (A. muciniphila), both FOsA and FOsB significantly modulated its mucin-degrading enzyme activities (p\u00a0<\u00a00.05). Specifically, both fractions increased sialidase activity while reducing \u03b1-N-acetylglucosaminidase and \u03b2-galactosidase activities. Notably, FOsA, with a higher FAX3/FAX2 ratio, exhibited significantly stronger inhibition of exo-\u03b1-L-fucosidase activity than FOsB (p\u00a0<\u00a00.05). These findings demonstrate that FOs act as effective modulators of A. muciniphila enzymatic functions rather than metabolic substrates, and that their fine structural composition critically influences their regulatory potency on mucin-degrading enzymes, with potential implications for maintaining intestinal mucus barrier integrity.\n\nID: 42505969\nTitle: Salicornia europaea L. as a Marine Bioactive Resource: Phytochemical Profile, Health Mechanisms, and Functional Applications in Precision Nutrition.\nAbstract: Marine halophytes are gaining attention as a source of plant-derived bioactive compounds with potential applications across nutraceuticals, functional foods, and preventive nutrition. Among them, Salicornia europaea L. is a coastal succulent whose adaptation to hypersaline environments shapes a distinctive phytochemical profile of pharmacological interest. This narrative review integrates current evidence on the bioactive composition, mechanistic activities, and translational relevance of S. europaea and related Salicornia species. Their secondary metabolome includes flavonols, isorhamnetin glycosides, hydroxycinnamic acids, oleanane-type triterpene saponins, fermentable polysaccharides, carotenoids, and a mineral-rich ionic matrix. Reported activities span antioxidant, anti-inflammatory, vascular-protective, anti-adipogenic, glycaemic-modulating, antimicrobial, and microbiome-related effects, mediated through pathways involving NF-\u03baB, PPAR-\u03b3, endothelial nitric oxide signalling, and short-chain fatty acid production. Beyond its individual phytochemical components, the matrix as a whole may also support sodium-reduction strategies in food formulation, providing a complementary nutritional rationale for its incorporation as a functional ingredient. Despite a coherent body of mechanistic and preclinical findings, clinical evidence remains limited, particularly regarding long-term efficacy, dose standardisation, and bioavailability in humans. Future work should prioritise adequately powered intervention trials and standardised characterisation of marine halophyte bioactives to clarify their evidence-based role in functional food development and future precision nutrition applications.\n\nID: 42499659\nTitle: Dynamic remodeling of the gut microbiome and host responses after myocardial infarction revealed by longitudinal metaproteomics.\nAbstract: The gut microbiota is increasingly recognized as a key regulator of cardiovascular health; however, its functional dynamics following myocardial infarction (MI) remain poorly defined. While traditional sequencing approaches focus on microbial composition, they cannot capture real-time functional activity. In this study, we established a rat model of MI via permanent ligation of the left anterior descending artery and collected fecal samples from MI and sham-operated cohorts at baseline and Days 2, 7, and 14 post-surgery. High-resolution metaproteomics was applied to quantify microbial and host proteins, integrating functional annotation, differential expression, and weighted gene co-expression network analysis (WGCNA). We observed an acute, generalized decline in microbial diversity at Day 2 across both groups, indicative of a physiological response to surgical stress. Crucially, MI-specific divergence emerged during the subacute phase (Day 7) and persisted into recovery (Day 14). At Day 7, functional perturbations peaked in the MI group, significantly involving carbohydrate metabolism, nucleotide biosynthesis, and oxidative stress pathways, accompanied by taxonomic shifts including the depletion of Akkermansia and enrichment of Odoribacter and Muribaculum. Concurrently, host-derived proteins displayed time-dependent alterations in lipid catabolism and redox regulation. WGCNA revealed co-regulated protein modules linked to MI status and the recovery phase, reflecting highly synchronized host-microbiome responses. This time-resolved metaproteomic study demonstrates that following initial surgical stress, MI triggers dynamic, stage-specific alterations in gut microbial function and coordinated host responses, providing mechanistic insights into the gut-heart axis and suggesting potential microbiota-targeted strategies to promote post-MI recovery.\n\nID: 42482939\nTitle: Modulation of gut microbiota and intestinal barrier by lotus seed, jujube, and longan aril in senna leaf-induced diarrhea in mice.\nAbstract: This study aimed to investigate the regulatory effects of lotus seed, jujube, and longan aril on the gut microbiota structure and barrier function in a senna leaf-induced diarrhea mouse model. Diarrhea was induced in ICR mice using senna leaf extract. Mice received aqueous extracts of lotus seed, jujube, or longan aril for treatment. Intestinal motility was assessed through fecal consistency scoring and the charcoal propulsion test. Colon tissues were collected for histopathological examination using H&E staining, as well as immunohistochemical and Western blot analyses of aquaporin 3 (AQP3) and sodium-hydrogen exchanger 8 (NHE8). Gut microbiota composition was analyzed via 16S rRNA sequencing. All three herbal interventions significantly reduced the loose stool rate and diarrhea index (p\u202f<\u202f0.05), inhibiting small intestinal hypermotility. Histological analysis revealed an increase in goblet cell numbers and improved crypt architecture in the colon. Immunohistochemical evaluation indicated downregulation of AQP3 and upregulation of NHE8 expression, which was confirmed by Western blot analysis. 16S rRNA sequencing demonstrated that all treatments restored \u03b1-diversity (Shannon index, p\u202f<\u202f0.05). \u03b2-diversity analysis revealed that longan aril induced a more extensive reshaping of gut microbial community structure compared to lotus seed and jujube, which exhibited a \"phased\" restoration. The relative abundance of potential pathogens (e.g., Akkermansia muciniphila, Citrobacter spp.) significantly decreased, while beneficial short-chain fatty acid-producing bacteria (e.g., Blautia coccoides, Faecalibaculum rodentium, Alloprevotella rava) were enriched. Unique protective taxa, such as nitrogen-fixing Azospirillum and antioxidant Deinococcus, emerged in specific treatment groups. Lotus seed, jujube, and longan aril synergistically alleviated diarrhea via multiple pathways, including modulation of gut microbiota structure, repair of barrier function, balance of water-electrolyte metabolism, and inhibition of intestinal hypermotility. This study provides a scientific foundation for the clinical application of medicinal and edible homology substances, as well as the development of microecological agents.\n\nID: 42456388\nTitle: Integrating multi-omics reveals the protective effects of Lycium ruthenicum anthocyanins against radiation pneumonitis through gut-lung axis modulation.\nAbstract: Radiation pneumonitis (RP) is a dose-limiting complication of thoracic radiotherapy, and effective preventive interventions remain limited. Lycium ruthenicum anthocyanins (LRACN) exhibit antioxidant and anti-inflammatory activities, but their effects on RP and the associated systemic mechanisms remain unclear. In this study, a mouse RP model was established by 15\u202fGy localised chest irradiation, and LRACN was administered orally before and after irradiation. Protective effects were evaluated using histopathology, inflammatory cytokines, and oxidative stress indices. Potential mechanisms were explored by integrating 16S rRNA sequencing, non-targeted serum metabolomics, metabolite-based target network analysis, transcriptomics, and single-cell RNA-seq. Compared with the model group, high-dose LRACN reduced injury score, collagen volume fraction, tumour necrosis factor-\u03b1, and malondialdehyde in the lung tissue by approximately 55%, 58%, 45%, and 44%, respectively. Multi-omics profiling revealed that LRACN partially restored radiation-disrupted gut microbial taxa, including Dubosiella, Ligilactobacillus, and Akkermansia, and reversed radiation-induced disturbances in serum purine and glycerophospholipid metabolism. Correlation analysis linked LRACN-responsive gut taxa and circulating metabolites with RP-related pathological, inflammatory, and oxidative indices. Integrated pathway analysis and western blotting suggested that the protective effect of LRACN was associated with reduced PI3K and Akt phosphorylation in lung tissue. These findings indicate that LRACN mitigates early RP in mice, and gut microbiota-associated metabolic remodelling may contribute to its protective effects.\n\nID: 42447972\nTitle: Short-chain fatty acid metabolism in acute lung injury and intervention strategies from traditional Chinese medicine.\nAbstract: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are severe conditions associated with high mortality rates and limited treatment options. Short-chain fatty acids (SCFAs) serve as central immunomodulatory metabolites mediate the crosstalk between the gut and lung. Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis. Meanwhile, to evaluate the therapeutic potential of TCM in treating ALI by modulating the gut microbiota and enhancing SCFA production. A comprehensive literature search was conducted across PubMed, Ovid-Embase, Web of Science, and CNKI databases (2010-2025). Keywords included \"short-chain fatty acid\", \"gut microbes\", \"acute lung injury\", \"traditional Chinese medicine\", and related terms. The search focused on preclinical and mechanistic studies investigating SCFA signaling, gut microbiota remodeling, and the therapeutic effects of herbal compounds or their active constituents in ALI/ARDS models. This review identified acetate, propionate, and butyrate as key mediators that protect against ALI through distinct mechanisms, including anti-oxidation, anti-inflammation, immunomodulation, apoptosis reduction, airway tight-junction protection, and regulation of intestinal homeostasis. In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate. SCFAs represent critical molecular mediators of the gut-lung axis, and their modulation by natural products offers a promising microbiota-centered strategy for ALI treatment. This microbiota-centered strategy holds great promise for ALI precision medicine.\n\nID: 42429666\nTitle: Sialidase inhibitor modulates gut microbiota and enhances mucosal protection in the treatment of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is characterized by mucosal barrier erosion, a process exacerbated by bacterial sialidases. We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.\n\nID: 42422874\nTitle: The role of gut microbiota dysbiosis in the pathogenesis of hyperuricemic nephropathy.\nAbstract: Hyperuricemic nephropathy (HN) is a renal complication associated with sustained hyperuricemia and urate-related renal injury. Emerging evidence suggests that gut microbiota dysbiosis may participate in HN pathogenesis by influencing uric acid metabolism, intestinal urate excretion, gut barrier integrity, microbial metabolite production, and gut-kidney immune crosstalk. However, the strength of evidence varies substantially across proposed mechanisms, with many findings derived from animal models, in vitro experiments, CKD studies, or human studies of hyperuricemia and gout rather than HN-specific clinical cohorts. This review summarizes current clinical and experimental evidence linking gut microbiota dysbiosis with HUA, gout, CKD, and HN, critically evaluates proposed mechanistic pathways, and discusses microbiota-targeted interventions including probiotics, prebiotics, dietary strategies, fecal microbiota transplantation, and metabolite-based approaches. Particular emphasis is placed on distinguishing association from causality and identifying translational gaps that should be addressed in future HN-specific studies.\n\nID: 42406268\nTitle: Huanglian-Wendan Decoction alleviates DSS-induced colitis by modulating the gut microbiota and protecting against intestinal injury via suppression of colonic apoptosis and endoplasmic reticulum stress.\nAbstract: Inflammatory bowel disease (IBD) is a chronic disorder characterized by recurrent intestinal inflammation and gut microbiota dysbiosis. Huanglian-Wendan Decoction (HLWDD) has been clinically used for IBD treatment; however, its underlying mechanisms remain unclear. In this study, a dextran sulfate sodium (DSS, 2.25%)-induced IBD mouse model was established to evaluate the therapeutic effects of HLWDD. The protective mechanisms were investigated in colon tissues of DSS-induced mice using ELISA, immunoblotting, histological, and immunohistochemical analyses. In addition, the impact of HLWDD on gut microbiota dysbiosis was analyzed using 16S rRNA sequencing. Antibiotic treatment was applied before DSS administration to deplete gut microbiota and verify the role of microbial modulation. Furthermore, the phytochemical constituents of HLWDD were characterized using liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (LC-QTOF-MS/MS). The results demonstrated that HLWDD markedly alleviated DSS-induced colitis, as evidenced by reduced body weight loss, rectal bleeding, colon shortening, and disease activity index (DAI) scores. Mechanistically, HLWDD suppressed inflammatory responses in colon tissues by inhibiting the TLR4/MyD88/NF-\u03baB and IL-6/JAK2/STAT3 signaling pathways, while enhancing epithelial barrier integrity through upregulation of ZO-1, Occludin, Claudin-1, and Mucin-2. In addition, HLWDD attenuated endoplasmic reticulum stress (ERS) and apoptosis by downregulating CHOP, phospho-eIF2\u03b1, cleaved caspase-3, and Bax, while increasing Bcl-2 expression in colonic tissues. Microbiota analysis revealed an increased abundance of beneficial bacterial genera such as Akkermansia and Escherichia-Shigella-related commensals, along with enrichment of beneficial bacterial families including Ruminococcaceae, Lachnospiraceae, and Verrucomicrobiaceae, whereas potentially harmful taxa such as Escherichia and Paraprevotella were reduced. HLWDD also increased the production of short-chain fatty acids (SCFAs), including acetate, butyrate, and isobutyrate, thereby promoting intestinal homeostasis. Importantly, the protective effects of HLWDD were largely abolished following antibiotic-mediated gut microbiota depletion, confirming the essential role of microbial modulation in its therapeutic action. Collectively, these findings suggest that HLWDD ameliorates IBD by regulating gut microbiota composition and function, thereby inhibiting colonic ER stress and apoptosis and restoring intestinal barrier integrity. This study provides mechanistic evidence supporting the potential clinical application of HLWDD as a novel therapeutic strategy for IBD.\n\nID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17A+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.\n\nID: 42380569\nTitle: Akkermansia muciniphila supplementation alters inflammatory profiles across diverse models of colitis.\nAbstract: Inflammatory bowel disease (IBD) is characterized by chronic intestinal inflammation and is thought to result from interactions among the immune system, environmental factors, and the gut microbiota in genetically susceptible individuals. Akkermansia muciniphila, a commensal bacterium has been reported to be depleted in individuals with IBD, although its precise role in intestinal inflammation remains unclear. This study examined the effects of A. muciniphila across multiple models of colitis, including dextran sulphate sodium (DSS)-induced colitis, the Mucin-2 knockout (Muc2-/-) model of spontaneous colitis, and Trichuris muris-mediated infectious colitis. In a DSS recovery model, treatment with pasteurized A. muciniphila reduced the severity of inflammation. However, when administered prior to DSS exposure, both live and pasteurized bacteria did not significantly reduce inflammatory markers, suggesting limited preventive effects. In T. muris-infected mice, supplementation with live A. muciniphila increased Th2 and anti-inflammatory cytokine responses, reduced parasite burden, and enhanced gene expression of the mucin Muc5ac. Additionally, both live and pasteurized A. muciniphila alleviated spontaneous colitis severity in Muc2-/- mice, indicating that these protective effects occur independently of Muc2. These findings expand understanding of the role of A. muciniphila in intestinal inflammation and highlight its potential as a therapeutic target for inflammatory intestinal disorders such as IBD.\n\nID: 42359789\nTitle: Mucin-derived sugars act as metabolic brakes controlling growth initiation in Akkermansia muciniphila.\nAbstract: Akkermansia muciniphila is a key member of the gut microbiota and plays important roles in host metabolism and health. In the colon, A. muciniphila extracts nutrients from oligosaccharide-rich mucin glycans that comprise the mucosa. However, this environment is complex and shaped by dietary inputs, microbiome metabolism, and mucin glycan composition varying across hosts, gastrointestinal regions, and physiological states. How strains of A. muciniphila integrate these nutrient signals into growth initiation and niche colonization remains unclear. Here, we compare physiological responses of a human- and mouse-derived strain of A. muciniphila, finding that dietary sugars differentially affect these isolates, suggesting host-associated tuning of metabolic capacity. In contrast, several mucin-derived sugars impose a conserved, concentration-dependent delay in growth initiation, implicating the lag phase as a critical metabolic checkpoint for growth. Genetic suppressor analysis identified sugar kinases and a component of the tricarboxylic acid cycle as genetically encoded control points linking glycan sugar exposure to the energy balance required for growth. These findings demonstrate that mucin-derived sugars function as both nutrients and metabolic stressors, regulating growth initiation. We propose that A. muciniphila employs metabolic \"brakes\" to coordinate growth with mucin composition, putatively linking host glycan landscapes to microbial physiology and ecological fitness within the mucus layer.\n\nID: 42356278\nTitle: Bioactive Low-Molecular-Weight Fraction from Limosilactobacillus fermentum CECT5716 Attenuates Intestinal Inflammation and Dysbiosis in DSS-Treated Mice.\nAbstract: Postbiotics, including cell-free supernatants and their fractions, have emerged as a safe and effective alternative to live probiotics for managing intestinal inflammation. This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis. By integrating epithelial protection, immunomodulation, and microbial reshaping, it represents a promising dietary strategy for the management of Inflammatory Bowel Diseases.\n\nID: 42353998\nTitle: Gut Microbiome Responses to Nutritional and Lifestyle Interventions in Pediatric Obesity: A Systematic Review Toward Precision Nutrition.\nAbstract: Background: Childhood obesity is increasingly associated with gut microbiome dysbiosis. This systematic review (PROSPERO CRD420251131354) evaluates evidence from studies published between 2020 and 2026 assessing how nutritional and lifestyle interventions influence gut microbiota in children with obesity. Methods: A systematic search of PubMed, EMBASE and EBSCO identified 21 interventional studies involving children aged 5-18 years with obesity, with the last search conducted in April 2026. Interventions comprised prebiotics, probiotics, synbiotics, postbiotics, high-fiber diets, calorie-restricted dietary approaches, and lifestyle modifications such as physical activity. Microbiome outcomes were analyzed using 16S rRNA sequencing, quantitative real-time polymerase chain reaction (qPCR), or metagenomics. Risk of bias was evaluated using the RoB 2 and ROBINS-I (version 2) tools. Due to substantial heterogeneity in study design, participant characteristics, intervention types, and analytical methods, a meta-analysis was not feasible. Results: Across 21 studies, nutritional interventions included measurable but heterogeneous alterations in gut microbiome composition. Inulin supplementation was associated with a significant increase in alpha diversity and with higher relative abundances of Bifidobacterium, Blautia, Megasphaera, Subdoligranulum, and Eubacterium coprostanoligenes. Synbiotic supplementation increased Prevotella and Dialister and reduced the Firmicutes/Bacteroidetes ratio. High-fiber dietary interventions increased Faecalibacterium, Bifidobacterium, and Clostridium, while reducing Bacteroides, and were associated with shifts in metabolic pathways related to carbohydrate, lipid, and nucleotide metabolism. Calorie-restricted diets and combined diet-exercise interventions increased beneficial taxa such as Akkermansia muciniphila, improved microbial diversity, and correlated with favorable metabolic and anthropometric outcomes. Overall, nutritional and lifestyle interventions in pediatric obesity were associated with taxon-specific and context-dependent microbiome changes, rather than uniform restructuring. Conclusions: Nutritional interventions can modulate gut microbiota diversity, composition, and predicted function in pediatric obesity; however, the observed effects vary substantially across studies. The limited number of trials, small sample sizes, and methodological heterogeneity underscore the need for larger, standardized studies to better define clinical and therapeutic implications.\n\nID: 42352300\nTitle: The Gut-Lung Microbiome Crosstalk and Pulmonary Disease.\nAbstract: Both the gut and the lungs possess a microbiome, a community of commensal bacteria, archaea, fungi, and viruses that perform important housekeeping functions in those organs. The colonic microbiome primarily ferments indigestible dietary fibers into essential short-chain fatty acids, synthesizes essential vitamins, regulates the mucosal immune system, and forms a protective barrier against pathogenic colonization. The lung microbiome maintains respiratory health primarily by regulating mucosal immunity, providing a physical barrier against invading pathogens, and producing beneficial metabolites. Several colonic microbiota metabolites, including the short-chain fatty acids acetate, propionate, and butyrate, together with the tryptophan metabolites indole-3-acetate and indole-3-propionate, secondary bile acids, and the polyamines spermidine and putrescine, are transported to the lungs via the gut-lung axis. These colonic microbiota biomolecules suppress lung inflammation, strengthen immune homeostasis, and reduce the severity of respiratory diseases. In contrast, lung microorganisms and their metabolites can travel to the gut via the gut-lung axis, influencing intestinal immune responses and potentially leading to an imbalance of gut microorganisms or dysbiosis. This means that respiratory diseases may lead to digestive issues, intestinal inflammation and chronic diseases. Here, we have reviewed this crosstalk and its impact on the principal pulmonary diseases: asthma, chronic obstructive pulmonary disease, cystic fibrosis, bronchogenic carcinoma, COVID-19, interstitial lung diseases, pneumonia, and tuberculosis. It is concluded that the gut microbiome plays a significant part in lung health and disease. Diet, tobacco smoking and electronic cigarette vaping all impact both the gut and lung microbiomes.\n\nID: 42346391\nTitle: Multi-Targeted Intervention of Eucommia ulmoides and Its Bioactive Constituents Against Metabolic Syndrome: From Molecular Mechanisms and Gut Microbiota Modulation to Clinical Translation.\nAbstract: Background/Objectives: Metabolic syndrome (MetS) is a pressing global health challenge comprising obesity, hyperglycemia, hypertension, and hyperlipidemia. Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.\n\nID: 42335777\nTitle: Effects of dietary L-Citrulline or L-arginine supplementation on immune function, intestinal morphology and intestinal microbiota in LPS-challenged broilers.\nAbstract: This study aimed to investigate the effects of dietary L-citrulline (L-Cit) or L-arginine (L-Arg) supplementation on jejunal mucosal barrier function and inflammatory response in broilers under lipopolysaccharide (LPS) challenge. A total of 384 one-day-old yellow-feathered broilers were randomly divided into 4 groups with 8 replicates per group and 12 birds per replicate. The control group and LPS group were fed a basal diet, while the L-Cit group and L-Arg group were supplemented with 1% L-Cit and 1% L-Arg in the basal diet, respectively. The experiment lasted for 27 days. On days 22, 24, and 26 of the experiment, broilers in the control group were intraperitoneally injected with 1 mg/kg body weight of saline, while those in the LPS group, L-Cit group, and L-Arg group were intraperitoneally injected with 1 mg/kg body weight of LPS. The results showed that no significant effect on growth performance of 21d broilers was observed among all groups (P > 0.05). Both the L-Cit group and L-Arg group significantly or extremely significantly increased the levels of T-AOC, SOD, IgG, and IgM (P < 0.05 or P < 0.01), and significantly decreased the levels of IL-6 and TNF-\u03b1 (P < 0.05 or P < 0.01). Hematoxylin-eosin staining and immunofluorescence analysis revealed that L-Cit alleviated intestinal villus atrophy and enhanced intestinal barrier integrity induced by LPS challenge. Notably, both L-Cit and L-Arg regulated the structure of the intestinal microbial community. L-Arg primarily promoted the abundance of beneficial bacteria such as g_Faecalibacterium and g_Barnesiella, whereas L-Cit significantly promoted g_Akkermansia to become the dominant genus and exert its function.\n\nID: 42316904\nTitle: The Role of Fecal Microbiome Transplantation in Steroid Hyporesponsive Asthma.\nAbstract: Asthma is a chronic inflammatory airway disease characterized by airflow obstruction, airway hyperresponsiveness, and structural remodeling. Corticosteroids remain the mainstay of asthma therapy; however, a substantial proportion of patients with severe disease develop steroid hyporesponsiveness, limiting therapeutic efficacy and increasing disease burden. Emerging evidence implicates the gut microbiome as a key regulator of systemic immune responses, with growing relevance to asthma pathogenesis and treatment responsiveness. In this study, we investigated whether gut microbiota dysbiosis contributes to steroid hyporesponsive lung inflammation and whether fecal microbiota transplantation (FMT) can restore steroid responsiveness. Using a steroid-hyporesponsive asthma model, we demonstrate that the disease is associated with significant gut microbial dysregulation, characterized by reduced microbial diversity and depletion of immunoregulatory taxa. FMT partially restored gut microbial diversity, normalized community structure, and selectively replenished beneficial commensal bacteria, including Akkermansia muciniphila and Faecalibacterium prausnitzii, while suppressing pathogenic taxa. Importantly, restoration of gut microbial balance was associated with attenuation of lung inflammation and improved steroid responsiveness. These findings support a functional gut-lung axis in steroid hyporesponsive asthma and identify modulation of gut microbiota as a potential therapeutic strategy. Incorporating microbiota-directed interventions such as FMT may represent a novel adjunct approach for the management of refractory steroid-hyporesponsive asthma.\n\nID: 42316508\nTitle: Macromolecular Organization in Lentinula edodes: Integrating Co-Occurring Bioactives for Structure-Function Relationships Across Gut Microbiota and Host Metabolism.\nAbstract: Diet-microbe-host interactions are increasingly recognized as properties of complex food matrices rather than the sum of isolated compounds. Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems.\n\nID: 42312862\nTitle: A phase-variable capsule facilitates Akkermansia muciniphila colonization of the intestinal mucus layer.\nAbstract: Akkermansia muciniphila is a mucophilic commensal bacterium that significantly impacts metabolic and immune homeostasis. However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment.\n\nID: 42570615\nTitle: Taxifolin ameliorates radiation-induced colitis via the gut microbiota-BAs-FXR/NLRP3 axis.\nAbstract: Radiation-induced colitis (RC) poses a substantial clinical challenge with limited therapeutic options. Taxifolin (TAX), a natural flavonoid, exhibits potential anti-inflammatory properties; however, its clinical application is hindered by poor oral bioavailability and an unclear mechanism of action in the context of radiation injury. This study aims to investigate the therapeutic potential and underlying mechanisms of the flavonoid monomer TAX in the context of RC, with a particular focus on the gut microbiota-BAs-FXR/NLRP3 axis. We employed a 13 Gy total abdominal irradiation (TAI) mouse model and HIEC-6 cells. Multi-omics approaches, including 16S rRNA sequencing and untargeted metabolomics, were used to map microbiota and metabolic profiles. Crucially, to establish causality, fecal microbiota transplantation (FMT) was performed to assess the microbiota's mediating role, and the specific FXR antagonist DY268 was utilized to verify the dependency on FXR signaling. Molecular interactions were confirmed via molecular docking, drug affinity responsive target stability (DARTS), and co-immunoprecipitation (Co-IP) assays. TAX significantly mitigated RC, characterized by preserved intestinal barrier integrity and reduced inflammatory cytokine production. It reshaped microbial homeostasis, specifically enriching bile acid (BA)-metabolizing genera (such as Lachnoclostridium) and promoting the accumulation of specific FXR-activating BAs, including glycocholic acid (GCA), taurochenodeoxycholic acid (TCDCA), and ursodeoxycholic acid (UDCA). FMT from TAX-treated donors successfully recapitulated the radioprotective phenotype in recipient mice, confirming the causal role of the gut microbiota. Mechanistically, both TAX and the enriched BAs directly bound to the farnesoid X receptor (FXR), inducing conformational changes that enhanced its physical interaction with NLRP3, thereby inhibiting inflammasome assembly and downstream signaling. Importantly, pharmacological blockade of FXR by DY268 abolished the protective effects of TAX, confirming that FXR activation is indispensable for its therapeutic action. TAX mitigates RC not merely as an antioxidant, but as a microecological modulator. Importantly, TAX acts as a natural modulator of the \"gut microbiota-BAs-FXR/NLRP3\" signaling axis for RC therapy. TAX-induced microbiota changes promote the production of specific bile acids that amplify intestinal FXR signaling to suppress inflammation. This study provides a robust mechanistic basis for using TAX as an orally active radioprotectant targeting the gut-liver axis.\n\nID: 42569868\nTitle: A Universal Fenton-Like Strategy for Selective Generation of 1O2 in Mixed Industrial Wastewater Treatment and Green Chemical Synthesis.\nAbstract: Sustained and selective generation of singlet oxygen (1O2) in Fenton-like catalytic systems is highly desirable for diverse applications, from freshwater resource management to green chemical synthesis. Despite advances in advanced oxidation processes, there remains a lack of generalizable methods that reliably modulate 1O2 selectivity. Here, we propose a descriptor-assisted coordination modulation strategy, in which machine-learning analysis identifies the d-band center as an important electronic descriptor associated with 1O2 selectivity. Through N-coordination modulation, the CoN5 catalyst exhibited near-complete 1O2 selectivity among the quantified reactive oxygen species (ROS) with a steady-state concentration of 394 \u00b5M, outperforming recent reports. As an internal-circulation pre-oxidation module, the CoN5/peroxymonosulfate (CoN5/PMS) system continuously raised wastewater biochemical oxygen demand/chemical oxygen demand (BOD/COD) to above 0.5 over 192\u00a0h, increased bioavailable dissolved organic matter (DOM), and showed high microbiome compatibility, evidenced by reduced Vibrio fischeri inhibition and microbial diversity ordination clustering near the background with greater shared-taxa overlap. This system also enabled selective thioanisole oxidation, achieving 90.6% conversion and 99.5% selectivity, with green synthesis potential demonstrated in a three-chamber continuous single-pass reactor. These results establish a generalizable coordination principle for steering ROS pathways and provide a deployable, low-ecological-risk route for both mixed wastewater treatment and green chemical synthesis.\n\nID: 42568853\nTitle: Development of fermentation and respiration bioprocesses for efficient nitrogen removal through microbial catabolism.\nAbstract: Conventional activated sludge processes are primarily designed for nitrogen and phosphorus removal, with carbon transformation regarded as a concomitant process that supports downstream denitrification rather than a proactively regulated process. Inspired by the metabolic division of labor in gut ecosystems, we proposed and validated a metabolism-guided strategy for an experimental membrane bioreactor (MBR-E) with a prefermentation unit that couples upstream fermentation with downstream denitrification to restructure carbon flux toward more bioavailable electron donors for nitrogen removal. Long-term operation showed that MBR-E achieved significantly lower effluent total nitrogen (7.9 \u00b1 2.4 mg/L) compared with the control MBR system (MBR-C, 12.3 \u00b1 3.5 mg/L), which was attributed to its elevated specific denitrification rate. Influent organics were efficiently converted into volatile fatty acids (VFAs) via fermentation and shortening hydraulic retention time from 0.67 h to 0.5 h shifted VFA composition from propionate/butyrate dominance to acetate enrichment. Further, 16S rRNA gene sequencing demonstrated that functional denitrifiers and nitrifiers were selectively enriched in MBR-E. Co-occurrence network analysis revealed strengthened cooperative interactions and tighter functional coupling between carbon degradation and nitrogen removal in MBR-E. Overall, this study demonstrates that fermentation-driven carbon reprogramming can effectively regulate downstream respiratory pathways and reshape the microbial community structure, providing a novel approach for efficient nitrogen removal from low-carbon/nitrogen wastewater.\n\nID: 42568521\nTitle: Geographic origin and wheat variety shape microbial and functional profiles of brewing wheat for Daqu fermentation.\nAbstract: Wheat is the primary raw material for traditional Baijiu Daqu fermentation, yet its role as a carrier of functional microbiota and its contribution to Daqu quality remain poorly understood. A total of 135 wheat samples representing five geographic regions and nine cultivars were subjected to sensory evaluation, physicochemical analysis, and 16S rRNA gene and ITS amplicon sequencing. Microbial community composition, predicted functional potential, and their associations with wheat quality traits were analyzed using PICRUSt2, Mantel tests, and correlation analyses. Sensory evaluation indicated that the cultivation environment had a greater impact on Daqu quality than wheat cultivar, with wheat from the Dayi region and the MM916 cultivar exhibiting the most favorable characteristics. Sequencing identified 1,732 bacterial and 484 fungal amplicon sequence variants (ASVs), revealing significant geographic and varietal differences in microbial communities, while core taxa dominated by Pseudomonadota and Basidiomycota were consistently detected across all samples. Functional prediction suggested that microbial communities were primarily enriched in metabolic pathways, particularly carbohydrate metabolism, energy metabolism, and cofactor and vitamin metabolism. Spatial variation was observed in starch and sucrose metabolism, acetoin biosynthesis, and enzymes such as \u03b2-glucosidase and alcohol dehydrogenase. Wheat quality traits, especially protein, starch, and wet gluten content, were significantly associated with microbial composition and predicted functions. Thirty-two genera, including Sphingomonas, Pedobacter, and Martelella, showed strong correlations with these quality traits. Geographic origin and wheat cultivar jointly shape the microbial communities and functional potential of brewing wheat, providing pre-existing microbial resources that may influence early Daqu fermentation and flavor formation. These findings offer a microbiome-based framework for evaluating and selecting high-quality wheat for Baijiu production.\n\nID: 42568500\nTitle: Flavonoids in MASLD: preclinical mechanisms, pharmacological targets, and translational challenges.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most prevalent chronic liver disease worldwide, yet no pharmacological therapy has achieved regulatory approval. Flavonoids, plant-derived polyphenols encompassing seven structural subclasses, exhibit considerable preclinical promise through multi-target mechanisms but face translational barriers owing to poor oral bioavailability and insufficient clinical validation. This review systematically evaluates 33 structurally characterized single flavonoids for their therapeutic mechanisms, pharmacological targets, and translational prospects in MASLD, integrating evidence from cellular models, diverse rodent models, and available clinical trials. A tiered evidence classification (Levels A-C) was applied based on clinical data availability, multi-model validation, mechanistic depth, and study design rigor. Mechanistically, flavonoids restore hepatic lipid homeostasis by concurrently inhibiting SREBP-1c-mediated de novo lipogenesis and promoting PPAR\u03b1-driven fatty acid \u03b2-oxidation via AMPK activation; ameliorate insulin resistance through IRS-1/PI3K/Akt signaling; attenuate hepatic inflammation by suppressing NF-\u03baB/NLRP3 inflammasome cascades; reinforce antioxidant defenses via Nrf2/ARE-mediated induction of HO-1, SOD, and GPX4 with concomitant ferroptosis inhibition; enhance autophagic-lysosomal lipid clearance through TFEB nuclear translocation and Sirt1-dependent lipophagy; and remodel gut microbiota composition to fortify intestinal barrier integrity. Genistein, dihydromyricetin, quercetin, and kaempferol exemplify polypharmacological engagement across multiple pathways. Despite robust mechanistic evidence, oral bioavailability remains limited to 1%-5% owing to poor aqueous solubility, extensive phase II conjugation, and food-matrix interactions. Emerging strategies-carbamate prodrugs, nanoliposomes, biomimetic nanoemulsions, and colon-targeted nanoparticles-demonstrate feasibility in surmounting these barriers. Clinical evidence reveals compound-specific efficacy profiles: hesperidin reduces steatosis and transaminases; genistein improves insulin sensitivity; naringenin ameliorates lipid profiles without altering fibrosis markers. Critical appraisal identifies persistent limitations including small sample sizes, predominant reliance on male animals, short intervention durations, and absence of biopsy-confirmed endpoints. Future research must prioritize rigorous multicenter randomized controlled trials with optimized formulations, comparative efficacy studies, systematic safety evaluations, and multi-omics integration to bridge the translational gap toward evidence-based flavonoid therapeutics for MASLD.\n\nID: 42567842\nTitle: The Gut Microbiome in Foodborne Microplastic Toxicity: Mechanistic Insights and Human Health Risk Assessment.\nAbstract: Microplastics (MPs) are emerging foodborne contaminants with increasing implications for gastrointestinal health. However, the mechanistic basis linking dietary MP exposure to gut dysbiosis and intestinal dysfunction remains poorly resolved, limiting robust human health risk assessment. This review critically synthesizes current evidence on foodborne MPs, dietary exposure, and the physicochemical determinants of gastrointestinal fate, bioavailability, and toxicity. We examine the molecular and microbiome-mediated mechanisms linking MPs exposure to intestinal dysbiosis, barrier dysfunction, oxidative stress, immune activation, and metabolic reprogramming. Particular attention is given to the role of MPs as vectors for co-contaminants, which can amplify toxicity through synergistic interactions and reshape host-microbiome responses. We highlight advances in dynamic colon simulation and integrated multi-omics that unravels the mechanism underlying MP-induced intestinal toxicity. Current evidence indicates that gut microbiome dysregulation is a key mechanism driving foodborne MP-induced intestinal dysfunction and systemic toxicity. This review integrates multidisciplinary evidence to identify critical knowledge gaps and guide future research on the mechanisms, exposure, and health risks of foodborne microplastics.\n\nID: 42567420\nTitle: High-fat diet and age disrupt a Muribaculaceae-associated SCFA network linked to gut barrier and cognitive deficits.\nAbstract: Both diet and aging shape the gut microbiota, yet how their combined remodeling propagates across microbial function to host barrier and brain outcomes remains poorly understood. Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions. In an intervention setting, butyrate supplementation partially ameliorated inflammatory and barrier-related readouts and improved behavioral performance.\n\nID: 42567355\nTitle: Therapeutic application of probiotic extracellular vesicles in inflammatory bowel disease.\nAbstract: The chronic, recurring nature of Inflammatory bowel disease (IBD) and the complications associated with conventional drugs have driven the search for next-generation therapies capable of overcoming the limitations of current treatment regimens. As functional proxies of their parent bacteria, probiotic extracellular vesicles (PEVs) have become the focus of attention in recent years because of their great potential in the treatment of IBD. This review summarizes the overview of PEVs and recent advances of PEVs on the therapeutical effect and potential mechanisms in IBD. In addition, the review discusses the possible applications and challenges of PEVs in IBD. Key scientific concepts of review: PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Although PEVs offer powerful innovations for the treatment of IBD, they still face challenges such as high-quality and scaled-up production, purification, safety, target specificity, and bioavailability. Consequently, future investigations will focus on establishing standard procedures of isolation, purification, and quality control while engineering PEVs for enhanced target-specific delivery in IBD treatment.\n\nID: 42567327\nTitle: Akkermansia muciniphila gavage alleviates depression-like behaviors in female A53T \u03b1-synuclein transgenic mice.\nAbstract: Parkinson's disease (PD) is characterized not only by progressive motor deficits but also by non-motor symptoms, such as depression, which often emerge during the prodromal stage and significantly impair quality of life. While Akkermansia muciniphila (AKK) has shown potential in modulating neuroinflammation, its specific role and underlying mechanisms in alleviating PD-associated non-motor symptoms remain unclear. In this study, we investigated the effects of AKK intervention in 16-month-old female A53T \u03b1-synuclein (\u03b1-syn) transgenic mice. Behavioral assessments revealed that oral administration of AKK significantly ameliorated depression-like behaviors, evidenced by reduced immobility in the forced swim test and increased sucrose preference, without affecting motor function, spatial memory, or gastrointestinal motility. Mechanistically, the intervention exhibited genotype-specific effects: AKK significantly increased plasma 5-HT levels in C57 mice. This increase was associated with an enrichment of Lactobacillus taiwanensis and metabolic pathways favoring peripheral tryptophan conversion. Conversely, in A53T mice, the treatment specifically elevated hippocampal 5-HT levels without altering plasma concentrations. This central effect correlated with distinct microbial remodeling, characterized by the enrichment of butyrate/propionate-producing Lachnospiraceae and the activation of purine degradation. Collectively, these findings provide novel mechanistic insights into the therapeutic potential of AKK for managing non-motor symptoms in PD. While limited to a female cohort, our results suggest that AKK ameliorates depression-like behaviors in PD through sex-specific remodeling of the gut microbiome and serotonergic signaling.\n\nID: 42566826\nTitle: Spatiotemporal heterogeneity drives acetic acid fermentation of traditional Chinese aromatic vinegar: Insights into microbiota dynamics and flavor formation.\nAbstract: To address the ecological implications of spatiotemporal heterogeneity on microbial assembly and flavor formation in Chinese aromatic vinegar, this study systematically revealed these dynamics during the solid-state acetic acid fermentation (AAF). Temporally, Lactobacillus, Acetobacter, and Komagataeibacter synergistically drove acid and aroma formation. In the early stage (day 1), Lactobacillus dominated, creating an acidic niche for Acetobacter. During the main fermentation stage (days 7 to 13), Acetobacter oxidized ethanol to acetic acid, while Lactobacillus accumulated lactic acid, facilitating ester production. In the late stage (day 21), increased Komagataeibacter abundance further enhanced the accumulation of acetic acid and ketones. Spatially, oxygen availability created distinct metabolic zones: the aerobic upper layer favored rapid acetic acid accumulation by the proliferation of Acetobacter and Komagataeibacter. The middle layer served as a metabolic transition zone. The anaerobic lower layer dominated by Lactobacillus accumulated lactic acid, alcohols, and esters. Bacterial community assembly shifted from stochastic to deterministic processes, with high-abundance Acetobacter and Lactobacillus (over 90%) reinforcing metabolic synergy through environmental filtering. The layer-by-layer turning process gradually reduced spatial heterogeneity, converting compartmentalized metabolism into integrated synergy, thereby ensuring balanced accumulation of aromatic compounds and maintaining acid production efficiency.\n\nID: 42566139\nTitle: Mixed solid-state fermentation and microbial consortium improved the nutritional value of mulberry leaves and distillers' grains.\nAbstract: The rapid expansion of the livestock sector has precipitated a substantial surge in animal feed demand, necessitating immediate exploration and development of alternative feed sources to ensure sustainable supply. Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources.\n\nID: 42564885\nTitle: A mannogalactoglucan from steam-exploded Hericium erinaceus: structural elucidation, digestion resistance and gut microbiota-modulating prebiotic activity.\nAbstract: Steam explosion (SE) pretreatment effectively enhanced the extraction yield and bioactivity of polysaccharides from Hericium erinaceus (H. erinaceus), demonstrating notable therapeutic potential. In this study, a polysaccharide fraction (Q60E) was isolated from SE-treated H. erinaceus. Structural analysis revealed that Q60E (M w , 8.89\u00a0\u00d7\u00a0104\u00a0g/mol) was a mannogalactoglucan, featuring a backbone of \u21923)-\u03b1-Manp-(1\u2192, \u21926)-\u03b2-Glcp-(1\u2192, \u21923,6)-\u03b2-Glcp-(1\u2192, \u21923)-\u03b1-Glcp-(1\u00a0\u2192\u00a0and \u21924,6)-\u03b2-Galp-(1\u00a0\u2192\u00a0linkages with side chains of \u21924)-\u03b1-Glcp-(1\u00a0\u2192\u00a0and terminal \u03b2-Glcp-(1\u00a0\u2192\u00a0residues. Based on the shape factor \u03c1 (1.71) and the Mark-Houwink-Sakurada parameter (exponent \u03b1, 0.51), Q60E adopted a random coil conformation in aqueous solution. In vitro fermentation studies demonstrated that Q60E modulated gut microbiota by promoting beneficial genera (Lactobacillus, Lachnospira and Bifidobacterium) while suppressing pathogenic Fusobacterium. Furthermore, Q60E fermentation additionally enhanced the acetic acid and total SCFAs production, underscoring its prebiotic capacity. These findings highlight the potential of the mannogalactoglucan from SE-pretreated H. erinaceus as effective prebiotics for gut health.\n\nID: 42564591\nTitle: Unveiling the distinctive features of Feng-flavor Daqu: A comparative study of microbial communities and volatile compounds.\nAbstract: Daqu acts as a multifunctional starter, providing essential microorganisms and enzymes for simultaneous saccharification and fermentation in Chinese Baijiu production. This work aims to reveal the distinct features among Feng-flavor Daqu (FXDQ) and the 3 main flavor types of Baijiu Daqu (Light-, Luzhou-, Sauce-flavor Daqu). FXDQ exhibited lower moisture content, and the higher acidity, esterifying power, liquefaction capacity. Microbially, Bacillus and Actinomyces dominated the bacterial community, whereas Saccharomycopsis was the predominant fungal genus. Across the four Daqu, 130 volatile compounds were detected and 16 of these were identified as key discriminators. Strong correlations were identified among the microbiota, physicochemical properties, enzyme activities, and volatile compounds. Moreover, PICRUSt2 was utilized to predict enzymes associated with the production of some important aroma compounds. These findings enhance our understanding of Daqu, particularly providing deeper insights into the unique characteristics of Feng-flavor Daqu, and offer a scientific basis for optimizing Daqu production processes.\n\nID: 42564588\nTitle: Enhancing Broiler Production With Humic Acid and Probiotics: Effects on Growth Performance, Carcass Traits, Immune Response, Gut Microbiota, and Economic Feasibility.\nAbstract: Humic acid and probiotics are increasingly used as natural alternatives to antibiotic growth promoters in poultry production. Humic substances have been reported to support nutrient absorption and gut health, while probiotics enhance microbial balance and immune function. This study aimed to evaluate the individual and combined effects of humic acid and probiotics on growth performance, carcass characteristics, immune parameters, caecal bacterial populations (Escherichia coli, Salmonella spp., and Lactobacillus spp.), and the financial feasibility of broiler production. A total of 195 one-day-old Lohmann Meat (Indian River) broiler chicks were allocated in a completely randomized design with five dietary treatments and 3 replicates of 13 birds each. Dietary treatments were as follows: a basal diet (control), a basal diet with 0.05% humic acid, a basal diet with 0.10% humic acid, a basal diet with 0.02% probiotics, and a basal diet containing both 0.05% humic acid and 0.02% probiotics. Dietary inclusion of humic acid or probiotics did not significantly affect (p > 0.05) body weight gain, feed intake, or feed conversion ratio at 28\u2009days (market age), but significant improvements were observed at 7, 14, and 21\u2009days. However, the combined supplementation of 0.05% humic acid and 0.02% probiotics significantly improved several carcass traits (thigh, drumstick, back, wing, and liver weights), reduced caecal pathogenic bacteria (E. coli and Salmonella spp.), increased beneficial Lactobacillus spp., and enhanced immune parameters (higher lymphocyte percentage and lower white blood cell counts) compared to the control (p < 0.05). Hematological values remained within normal physiological ranges across all treatments. Economic analysis revealed that the combined supplementation group recorded the highest net present value (176.44 USD), internal rate of return (43.51%), and benefit-cost ratio (1.22), and the shortest payback period (1.93\u2009years). Overall, this study demonstrated that dietary supplementation with humic acid and probiotics, particularly in combination, improved carcass traits, reduced pathogenic bacterial loads, enhanced selected immune parameters, and increased economic returns without affecting growth performance at 28\u2009days.\n\nID: 42564435\nTitle: Germinated Brown Rice: A Natural Source of Bioactive Compounds Boosting Human Health.\nAbstract: Germinated brown rice (GBR) has gained considerable attention as a functional food due to both nutritional and bioactive profiles as well as health-promoting properties. The present narrative review is aimed at summarizing and discussing available research on GBR, focusing on bioactive composition and potential to support human well-being. Based on available data, the germination process of brown rice enhances the bioavailability of key bioactive compounds, including polyphenols, \u03b3-aminobutyric acid, \u03b3-oryzanol, vitamins, and dietary fibers. Additionally, a substantial body of evidence supports the ability of GBR to exert beneficial physiological effects on the host, such as modulation of lipid and glucose metabolism, antioxidant and anti-inflammatory activities, and positive influences on gut microbiota composition. The use of GBR in formulating functional foods and nutraceutical supplements further highlights its versatility as a promising strategy in supporting human well-being.\n\nID: 42564241\nTitle: Characterization of the effects of nitrate and tungstate, alone or combined, and Salmonella Newport inoculation on rumen microbiota, fermentation, and Salmonella survivability in vitro.\nAbstract: Nitrate consumption by ruminants may enrich nitrate-respiring Salmonella in the gut. To test whether tungstate, an inhibitor of nitrate reductase, may prevent nitrate-promoted enrichment of Salmonella, ruminal microbes inoculated with or without 104 colony-forming units (CFU)/mL of Salmonella Newport were incubated for 26\u202fh under simulated rumen conditions with or without 10\u202fmM nitrate, 100\u202fmM tungstate, or their combination. Results indicated more nitrate was metabolized (p\u202f<\u202f0.05) by ruminal populations supplemented with nitrate alone than with nitrate and tungstate combined, with means (\u00b1 standard deviations) being 8.55\u202f\u00b1\u202f0.74 and 3.97\u202f\u00b1\u202f0.67\u202f\u03bcmol nitrate/mL, respectively. Nitrite accumulations were affected (p\u202f<\u202f0.05) by tungstate treatment, achieving 4.96\u202f\u00b1\u202f0.26 and 0.18\u202f\u00b1\u202f0.07\u202f\u03bcmol/mL in populations supplemented with nitrate alone or combined with tungstate, respectively, when not inoculated with S. Newport and achieving 1.95\u202f\u00b1\u202f0.18 and 0.06\u202f\u00b1\u202f0.01\u202f\u03bcmol/mL, respectively, when inoculated with S. Newport. Salmonella increased (p\u202f<\u202f0.05) in populations treated with tungstate, alone or combined with nitrate (5.82\u202f\u00b1\u202f0.10 and 5.57\u202f\u00b1\u202f0.15 log10 CFU/mL, respectively), compared to controls or nitrate-only supplemented populations (1.63\u202f\u00b1\u202f0.58 and 2.84\u202f\u00b1\u202f0.21 log10 CFU/mL, respectively). In populations not inoculated with S. Newport, the addition of nitrate, tungstate, or their combination increased (p\u202f<\u202f0.05) wild-type coliforms by 1.4 to 3.9 log10 units compared to untreated controls (2.67\u202f\u00b1\u202f0.18 log10 CFU/mL). In S. Newport-inoculated populations, tungstate treatment, alone or combined with nitrate, increased (p\u202f<\u202f0.05) coliforms by 2.8 to 3.2 log10 units compared to control and nitrate-only supplemented populations (3.06\u202f\u00b1\u202f0.48 and 3.49\u202f\u00b1\u202f0.06 log10 CFU/mL, respectively). Wildtype lactic acid bacteria were enriched by tungstate treatment and nitrate supplementation, alone or combined to 0.2 to 1.1 log10 units, compared to untreated controls (6.84\u202f\u00b1\u202f0.03 and 6.68\u202f\u00b1\u202f0.16 log10 CFU/mL, respectively). Methane production decreased by 70% (p\u202f<\u202f0.05) in populations supplemented with nitrate, whether alone or combined with tungstate, compared to untreated or tungstate-only treated populations (29.85\u202f\u00b1\u202f5.05 and 23.08\u202f\u00b1\u202f5.49\u202f\u03bcmol methane/mL of incubation fluid, respectively). These results indicate that tungstate treatment marginally decreased nitrate metabolism in the ruminal populations but surprisingly promoted Salmonella enrichment.\n\nID: 42564199\nTitle: Euonymus alatus in diabetes: a review of phytochemistry, pharmacokinetics, and anti-diabetic mechanisms.\nAbstract: Euonymus alatus: (EA), a traditional Chinese botanical drug documented in the Shennong Ben Cao Jing, has been investigated for its potential anti-diabetic effects. This review systematically examines the phytochemistry, pharmacokinetics, and anti-diabetic mechanisms of this botanical drug. Over 230 metabolites, including flavonoids, triterpenoids, and lignans, have been identified from EA. Pharmacokinetic studies remain limited; computational predictions suggest that some metabolites may exhibit oral bioavailability, but classical pharmacokinetic parameters have not been experimentally determined for any EA metabolite. Mechanistic studies demonstrate that EA exerts anti-diabetic effects through multiple experimentally validated pathways: (i) inhibiting alpha-glucosidase activity to delay intestinal glucose absorption; (ii) activating the peroxisome proliferator-activated receptor gamma and phosphatidylinositol 3-kinase/protein kinase B signaling pathways to ameliorate insulin resistance; (iii) modulating gut microbiota composition and increasing short-chain fatty acid production; (iv) suppressing the advanced glycation end products-receptor for advanced glycation end products axis along with the nuclear factor kappa B and mitogen-activated protein kinase inflammatory pathways to alleviate oxidative stress and inflammatory responses; and (v) regulating diacylglycerol acyltransferase activity to improve lipid metabolism. Preclinical studies indicate that EA reduces blood glucose and improves markers of diabetic nephropathy and retinopathy. Clinical studies of EA-containing formulations report reductions in fasting blood glucose and urinary protein. However, the clinical evidence remains limited by small sample sizes, lack of rigorous controls, and multi-botanical drug compositions that preclude attribution of effects to individual components. This review provides a critical synthesis of current evidence and identifies priorities for future investigation.\n\nID: 42564158\nTitle: Natural polysaccharides as immunometabolic modulators in metabolic diseases: mechanisms and translational challenges.\nAbstract: Metabolic disorders, especially obesity, type 2 diabetes mellitus, and metabolic dysfunction-associated steatotic liver disease, are becoming increasingly prevalent and have imposed a growing burden on public health systems. These diseases are commonly associated with insulin resistance and abnormal lipid metabolism, and increasing evidence indicates that immune imbalance and chronic low-grade inflammation are involved in their development. Natural polysaccharides are important bioactive components derived from plants, fungi, algae, and other natural sources. Current evidence supporting their beneficial effects in metabolic diseases is predominantly preclinical, mainly from cell-based and animal studies, while clinical evidence remains limited and heterogeneous. Natural polysaccharides have attracted interest as candidate bioactive compounds because some preparations have shown immunomodulatory and metabolic regulatory activities in experimental models. Their activities are closely related to structural features, including monosaccharide composition, glycosidic linkage types, molecular weight, branching structure, and chemical modification. Current preclinical evidence suggests that natural polysaccharides may alleviate metabolic inflammation by regulating macrophage polarization, suppressing pro-inflammatory cytokine production, modulating MAPK, NF-\u03baB, AMPK, and related signaling pathways, and reshaping the gut microbiota-immune axis. These compounds may help improve several pathological features of metabolic disorders, such as insulin resistance, abnormal lipid metabolism, inflammatory injury, and tissue dysfunction. However, several challenges still limit their translation, including unclear structure-activity relationships, inconsistent preparation standards, limited bioavailability, and insufficient well-designed clinical trials. Therefore, this review provides an overview of the natural sources, structural properties, immunomodulatory actions, and therapeutic prospects of natural polysaccharides in metabolic diseases, with a focus on their involvement in immune regulation and metabolic inflammation.\n\nID: 42564065\nTitle: Gut microbiota in anemia: mechanistic insights into iron metabolism, vitamin synthesis, and immune regulation.\nAbstract: The gut microbiota, as a vital micro-ecological system within the human body, plays a crucial role in regulating diverse physiological functions. Recent research has increasingly demonstrated its close association with the occurrence and progression of anemia. This review summarizes current understanding of how the gut microbiota influences iron metabolism, vitamin synthesis-particularly vitamin B12-and immune modulation, all of which are key factors in the pathogenesis of anemia. We explore the mechanisms by which dysbiosis of the gut microbiota contributes to anemia development, including disruptions in nutrient absorption and inflammatory responses. Furthermore, we analyze recent clinical studies that investigate the relationship between gut microbiota alterations and different anemia subtypes. By integrating the latest basic and clinical research findings, this review aims to provide a comprehensive overview of the gut microbiota's role in anemia and to highlight its potential as a novel therapeutic target. The insights offered here may guide future research and clinical interventions focused on microbiota modulation as an innovative strategy for anemia management.\n\nID: 42563498\nTitle: From Gut to Heart: The Emerging Role of Dietary Fermentable Fiber in Heart Failure with Preserved Ejection Fraction.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is a multisystemic syndrome that accounts for more than half of all heart failure cases and causes a substantial burden of morbidity and mortality. In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF.\n\nID: 42563484\nTitle: The gut microbiota plays a modifiable role in MS progression-YES.\nAbstract: \n\nID: 42562540\nTitle: Ecological mechanisms and functional stability of lactic acid Bacteria in synthetic microbial communities: Competition, cross-feeding, and homeostasis maintenance.\nAbstract: Synthetic microbial communities (SynComs) play a pivotal role in advancing precision fermentation and microbiome engineering. Within these multispecies systems, lactic acid bacteria (LAB) function as ecological and metabolic cornerstones. However, the mechanisms underlying LAB-mediated community stability remain insufficiently understood. This review synthesizes current knowledge on microbial competition, cross-feeding, and community homeostasis to evaluate the ecological contributions of LAB. We compare the metabolic roles of LAB in SynComs and natural ecosystems, highlighting competitive strategies, including acidification and antimicrobial production, as well as lactate-centered syntrophic interactions. As central metabolic hubs, LAB facilitate the division of labor by transforming excess metabolic outputs into shared resources, thereby reducing metabolic inefficiencies. We further examine how functional redundancy and metabolic coupling contribute to community resilience and stability. The review also discusses emerging applications of SynComs in gut health, particularly inflammatory bowel disease (IBD), and industrial fermentation processes. We conclude that the integration of multi-omics approaches with predictive modeling will be critical for the rational design and programmable regulation of stable microbial consortia. Furthermore, this review proposes a unified hierarchical framework for understanding the stability of LAB-mediated SynComs. By integrating competition-driven colonization, cooperation mediated through cross-feeding interactions, and multidimensional homeostatic mechanisms, the framework bridges fundamental ecological theory with applied microbiome engineering. The proposed framework is primarily applicable to LAB-centered SynComs associated with food fermentation systems, acidic environments, and lactate-driven metabolic networks.\n\nID: 42562527\nTitle: Fermented milk derived from a novel probiotic strain enhances digestive function and attenuates dextran sulfate sodium-induced colitis via the microbiota-metabolite-immune axis.\nAbstract: Probiotic-fermented dairy products are increasingly recognized for their dual role in nutrient optimization and disease prevention. This study investigated the mechanisms by which Bifidobacterium animalis subsp. lactis Probio-M8 fermented milk enhances digestive efficiency and protects against dextran sulfate sodium-induced colitis in rats. FM8 supplementation promoted weight gain without excessive adipogenesis, elevated leptin levels, and amplified sucrase, lactase, aminopeptidase, and lipase activities, outperforming conventional fermented milk. Metagenomic analysis revealed microbial restructuring with Corynebacterium glutamicum and Bifidobacterium animalis enrichment, and increased short-chain fatty acids.Untargeted metabolomics identified FM8-responsive metabolites, including p-hydroxybenzaldehyde and indole-3-carboxaldehyde, linked to anti-inflammatory pathways. In dextran sulfate sodium-challenged rats, FM8 pre-administration attenuated colitis severity by reducing disease activity index scores, normalizing colon histology, and suppressing interleukin (IL)-6 and IL-17 while elevating IL-10 and IL-22. Mechanistically, FM8 enriched Bifidobacterium animalis and butyrate levels, which inversely correlated with mucosal injury and pro-inflammatory cytokines. These findings demonstrate that FM8 enhances gastrointestinal health through tripartite microbiota-metabolite-immune interactions, highlighting its functional potential for metabolic optimization and colitis prevention.\n\nID: 42562520\nTitle: Growth stage vs. phyllosphere microbiota: dissecting their contributions to fermentation quality and bacterial community of fermented alfalfa.\nAbstract: A critical knowledge gap remains in disentangling the independent roles of growth stage and phyllosphere microbiota in driving fermentation profiles and bacterial community dynamics in fermented alfalfa. This study aimed to evaluate the respective contributions of alfalfa (Medicago sativa L.; AL) growth stage and phyllosphere microbiota to fermentation products, bacterial community diversity, co-occurrence networks, and functional potential using high-energy electron beam irradiation and microbiota transplantation methods. Alfalfa was harvested at the initial-flowering and full-flowering stages. The irradiated initial-flowering (AL1) and full-flowering (AL2) alfalfa were inoculated with 2\u00a0mL of phyllosphere microbiota inoculum eluted from the initial-flowering (AL1_IF, AL2_IF) and full-flowering (AL1_FF, AL2_FF) alfalfa, respectively. Chopped alfalfa (200\u00a0g fresh weight) was fermented in laboratory-scale plastic bags. Triplicate samples from each treatment were collected after 3 and 60\u00a0days of fermentation. After 60\u00a0days, growth stage exerted stronger effects on fermentation products, while phyllosphere microbiota significantly influenced bacterial community structure and co-occurrence network patterns. On day 60, AL1 groups exhibited higher (P\u00a0<\u00a00.05) acetic acid concentrations, pH, and proportions of potentially pathogenic bacteria than AL2 groups. Lactobacillus and Weissella dominated the bacterial community, with Pediococcus remarkably enriched in AL2 groups on day 60. Functional prediction indicated that glycolysis and lactate dehydrogenase were obviously upregulated during fermentation, and lactic acid was synergistically produced via both homolactic and heterolactic pathways. For practical production, initial-flowering alfalfa can be optimized by wilting or substrate supplementation, while full-flowering alfalfa benefits from inoculation with Lactobacillus and Pediococcus. These findings clarify the independent roles of growth stage and eluted phyllosphere microbiota and provide precise strategies for high-quality fermented alfalfa production.\n\nID: 42562513\nTitle: Cellar age reshapes Huangshui micro-ecosystem and metabolism to drive flavor formation in strong-aroma baijiu.\nAbstract: Huangshui, a slurry-like liquid exuded during strong-aroma Baijiu fermentation, serves as the core medium for material exchange between pit mud and fermented grains. However, how its micro-ecosystem evolves with cellar age and drives flavor formation remains unclear. Using Huangshui as a dynamic window, this study integrated metagenomics, metabolomics, and flavoromics to compare its temporal dynamics in new and old cellars over a complete fermentation cycle, systematically characterizing how cellar age is associated with the restructuring of the microbial community and metabolic functions of Huangshui, and how these changes are consistent with the flavor profiles observed in the final base liquor. The results showed that Huangshui from old cellars harbored a more diverse and stable microbial community, forming a syntrophic consortium of caproic acid-producing bacteria (Caproicibacterium, Caproiciproducens), syntrophic bacteria (Syntrophomonas), and methanogenic archaea (Methanosarcina), whereas new cellars were dominated by lactic acid bacteria (Acetilactobacillus). Metabolically, the old-cellar community exhibited a clear phase-dependent division. During the acid-producing phase, the TCA cycle, arginine biosynthesis, and pyruvate metabolism were preferentially activated to generate core precursors; during esterification, butanoate metabolism and acyl-CoA supply pathways were enhanced. This orderly shift was associated with higher concentrations of ethyl caproate and ethyl octanoate in old-cellar base liquor. Functional gene analysis revealed coordinated upregulation of chain-elongation, methanogenic, and acetate-activating pathways in old cellars. Network analysis revealed a tightly coupled caproic acid-producing co-occurrence module in old cellars, which was not observed in new ones. Together, these findings suggest that Huangshui may serve as a rapid proxy for assessing both the fermentation status and the maturity level of the cellar. This work identifies potential bioaugmentation targets to accelerate flavor development in new cellars and provides a theoretical basis for the precise micro-ecological management of strong-aroma Baijiu quality.\n\nID: 42562508\nTitle: Bacterial succession-guided three-stage temperature control stabilizes Huangjiu fermentation and shapes fatty acid ethyl ester profiles.\nAbstract: Temperature is a central lever linking microbial succession, fermentation stability, and aroma formation in mixed-culture cereal fermentations. This study investigated whether temperature control aligned with bacterial succession could stabilize Huangjiu fermentation and shape fatty acid ethyl ester (FAEE) profiles. Sequential screening identified 28\u00a0\u00b0C in stage I, 28\u00a0\u00b0C in stage II, and 20\u00a0\u00b0C in stage III as the benchmark schedule for robust fermentation, yielding the highest ethanol retention, balanced physicochemical traits, and the best terminal sensory quality. Further refinement showed that additional cooling did not further improve overall fermentation stability, as reflected by ethanol retention, acidification control, and terminal sensory balance, but selectively redirected terminal aroma formation. In S3-15, additional stage III cooling increased long-chain FAEEs by 112.7%. Stage II cooling in S2-24 increased medium-chain FAEEs by 80.0%, whereas combined cooling in S2-20/S3-15 produced the strongest medium-chain FAEE enrichment. Combined cooling in stages II and III produced the strongest terminal ester retention, increased medium-chain FAEEs by 2.81-fold, and enhanced selected aroma-active esters at the end of fermentation. Among the sequenced schedules, bacterial community analysis showed that stage-resolved cooling altered the timing of lactic acid bacteria (LAB)-dominated succession, and S2-20/S3-15 showed the strongest bacterial community-volatile organic compound (VOC) association. These findings support biologically aligned temperature control as an evidence-based strategy for stabilizing Huangjiu fermentation and provide broader insight into temperature-microbiota coordination in mixed-culture cereal fermentations.\n\nID: 42562486\nTitle: Microbial composition, dynamics, and functional roles in jinhua ham fermentation: integrating starter cultures and multi-omics for quality and safety.\nAbstract: Jinhua ham, a traditional Chinese dry-cured meat product with nearly a millennium of production history, derives its characteristic colour, layered aroma, and umami-rich taste from the coordinated biochemical activity of a dynamic microbial ecosystem across an eight-to-ten-month fermentation timeline. This review provides a critical synthesis of research between 2018 and 2025 on microbial composition, community dynamics, functional roles, safety risks, starter culture applications, and multi-omics characterisation of Jinhua ham fermentation, unified by precision fermentation as an organising framework. High-throughput sequencing has established that halotolerant bacterial genera, Staphylococcus, Psychrobacter, Halomonas, and Lactobacillus, and fungal communities comprising Aspergillus, Debaryomyces, Meyerozyma, and Penicillium undergo deterministic, physicochemically driven succession, with their enzymatic activities governing proteolysis, lipolysis, volatile compound formation, colour stabilisation, and the accumulation of biogenic amines, mycotoxins, and antimicrobial resistance genes (ARGs). Autochthonous starter cultures, including Staphylococcus xylosus, Lactiplantibacillus plantarum, and Penicillium aethiopicum, improve process controllability, safety, and sensory consistency, yet their mechanistic basis and validation remain incompletely established. Genomic and metabolomic approaches have generated datasets, but integrated metagenomics-metabolomics coupling, capable of linking microbial gene networks to flavour compound production, and metatranscriptomic characterisation of gene expression remain the unmet methodological needs. Five research directions are proposed: achieving species-level microbial resolution through long-read sequencing and longitudinal sampling; validating flavour-forming pathways through isotopic tracing and controlled inoculation; standardising analytical protocols for cross-study comparability; conducting starter culture and ARG safety validation; and developing low-salt fermentation strategies. Together, these directions define the research investment required to advance Jinhua ham production from empirical tradition to precision-engineered consistency.\n\nID: 42562480\nTitle: Fermentation of legumes as a strategy to enhance nutritional and sensory properties and modulate gut microbiome and human health.\nAbstract: Legumes represent a valuable and vegetable source of proteins and fiber with a very low environmental footprint production, therefore, both dietary guidelines and international agencies suggest increasing their production and consumption. Despite their favorable nutritional composition, they also naturally contain antinutritional factors such as phytic acid, that limit the absorption of micronutrients. This, coupled with the lower bioavailability of proteins as compared with meat, diminishes the biological and economic value of legumes. However, recent studies have shed a light on the power of fermentation to improve the protein profile of pulse and neutralize antinutritional compounds. In this review, we explore the benefits of legumes fermentation in depth, focusing on the role of microorganisms in enhancing the nutritional and sensory enhancement of legumes. Furthermore, we describe the properties and the microorganisms involved in the production of several craft-based fermented legumes typically consumed by non-Westernized populations, particularly delving into their effects on the gut microbiome and on the human health.\n\nID: 42562478\nTitle: Integrating ecological networks and metagenomics to decipher core microbial drivers of organic acid metabolism during heaped fermentation of sauce-flavor Baijiu.\nAbstract: Organic acids play crucial roles in both flavor quality and microbial succession of sauce-flavor Baijiu; however, the core microbial drivers responsible for their metabolism remain poorly understood. This study systematically investigated the microbial drivers of organic acid metabolism across six sequential rounds (R1-R6) of heaped fermentation. A total of 24 organic acids were identified, including nine non-volatile organic acids (NVOAs) and 15 volatile organic acids (VOAs). HPLC analysis revealed that the total content of acetic acid and nine NVOAs increased significantly across rounds, rising from 29.35\u00a0g/kg in R1 to 66.40\u00a0g/kg in R6. Lactic acid was the most abundant NVOA, while acetic acid, isovaleric acid, and hexanoic acid were the primary volatile contributors. Co-occurrence network analysis identified 488 consistently correlated bacterial pairs that clustered into two distinct guilds. Guild 2, mainly comprising Virgibacillus, Kroppenstedtia, Oceanobacillus, and Bacillus, exhibited high abundance (47%-78%) across all rounds and was defined as the core bacterial guild. Spearman correlation analysis revealed that guild 2 was positively correlated with NVOAs (69.41%) but negatively correlated with VOAs (63.02%). Metagenomic analysis reconstructed seven key pathways involved in organic acid biosynthesis. Kroppenstedtia, Lentibacillus, Desmospora, and Oceanobacillus were identified the taxa harboring the genetic potential most frequently detected across multiple pathways, with Kroppenstedtia and Lentibacillus exhibiting the highest gene abundances. These findings provide a theoretical foundation for targeted regulation of organic acid content in sauce-flavor Baijiu production.\n\nID: 42562466\nTitle: The dominance level of active dry yeasts reshaped the interactions between microbiota and metabolites during industrial wine fermentation.\nAbstract: The widespread use of commercial active dry yeasts (ADYs) in winemaking is well-established. Its successful implantation during industrial fermentation varies significantly according to wineries and regions. This inconsistency frequently causes undesirable quality fluctuations and deterioration. However, their interactions with native microbiota has not been fully elucidated. This study deciphers microbiota and metabolite profiles during industrial Cabernet Sauvignon wine fermentations with different implantation percentage of commercial active dry yeasts (ADYs) through multi-omics. Strain-level implantation percentages of ADYs were found to differ significantly among the studied wineries. High-throughput sequencing further showed differences in fungal and bacterial community structures between different dominance of ADYs. Metabolome analysis showed that 291 non-volatile metabolites represented the variations between high (80%) and low (50%) implantation percentage of ADYs. These metabolites were mainly involved in 20 different pathways, such as amino acids synthesis, cutin, suberine and wax biosynthesis. Also, significant differences in aroma profiles were observed between high and low dominance samples. Correlation analysis among microorganisms, non-volatile and volatile profiles revealed the effect of the implantation of ADYs on both microbial communities interactions and the resulting metabolite profiles, and highlighted the pivotal role of key microorganisms in shaping characteristic aromas. This study enhances understanding of how ADYs implantations affect microbial communities and metabolite profiles in wines, providing insights into a microbial \"terroir\" of relevance to wine character and wine quality.\n\nID: 42562459\nTitle: Food-derived dietary alkaloids: structure-biofunctionality relationships in modulating gut microbial biofilms for downregulation of colorectal carcinogenesis.\nAbstract: Colorectal cancer (CRC) is the second most common cancer across the globe, accounting for 10% cancer-related deaths annually. CRC has been recognized as a consequence of microbial (such as F. nucleatum, E. coli (pks+ strains) biofilms, inflammatory signaling, and redox imbalance in the human gut. Hence, natural bioactive substances as a part of the daily diet are crucial for the downregulation of biofilm-mediated CRC. Dietary alkaloids, nitrogen-containing secondary metabolites, have been identified as potential chemotherapeutic agents that can inhibit biofilm formation through quorum-sensing inhibition, modulating the tumor microenvironment, including redox and inflammatory pathway regulation. The present review primarily focuses on the alkaloids' structure-function relationships, microbial biotransformation, and inhibition of pathogenic biofilms, through downregulation of NF-\u03baB, IL-6, STAT3-mediated inflammatory cascades, apoptosis, induction of autophagy, and balancing the redox-oxidative homeostasis. Further, the synergistic effect of alkaloids with dietary fiber, short-chain fatty acid (SCFA)-mediated synergy, and polyphenol compounds is essential for microbial-epithelial barrier activity and metabolic homeostasis regulation. However, the integration of dose windows, dietary patterns, and regulatory landscapes is essential to establish dietary alkaloids as a functional food in biofilm-mediated CRC prevention. Moreover, bioavailability of dietary alkaloids is a potential challenge, and nano-enabled delivery, specifically lipid and polymeric nano carriers, is considered for the controlled delivery, mucosal bioactivity, and reduced systemic exposure of alkaloid carriers for colon mucosa bioactivity. Overall, the integration of microbiome with dietary alkaloids as bioactive food components, to modulate biofilm and tumor micro-niches, underlines the translational potential of dietary alkaloids for CRC prevention.\n\nID: 42562455\nTitle: The alleviative effect of protein-polysaccharide complex coacervation microcapsules on loperamide-induced constipation in mice.\nAbstract: The rising incidence of constipation and side effects of clinical drugs have spurred research on natural functional ingredients for its prevention and treatment. Probiotics and dietary fibers have diverse bioactivities but are limited by poor stability and low bioavailability. Herein, a novel microcapsule system co-loading Ganoderma lucidum dietary fiber (GLDF) and Lactobacillus fermentum CECT5716 was constructed using whey protein (WP) and xanthan gum (XG) via hybrid spray drying-complex coacervation. Optimal WP-XG interaction (driven by electrostatic forces and hydrogen bonds) was achieved at pH\u00a03.75 and 5:1 mass ratio; microcapsules with 1:1 wall-to-core ratio showed the best performance, with 72.3% post-encapsulation probiotic viability and enhanced stability under simulated gastrointestinal conditions and storage. Animal experiments confirmed that the microcapsules effectively alleviated loperamide (LOP)-induced constipation in mice, associated with regulating gut microbiota, promoting short-chain fatty acids (SCFAs) production, inhibiting colonic inflammation, repairing intestinal tight junctions, and downregulating aquaporins. In conclusion, the microcapsules prepared in this study provide a feasible strategy for the efficient co-delivery of probiotics and dietary fibers, and the developed composite functional ingredient holds great application potential in the field of constipation prevention and treatment.\n\nID: 42561489\nTitle: Neuroimmune mechanisms of the gut-brain axis in treatment-resistant depression: Implications for microbiome-based therapeutic strategies.\nAbstract: Treatment-resistant depression (TRD) represents a major clinical challenge characterised by inadequate response to conventional antidepressant therapies and high relapse rates. Emerging evidence suggests that TRD may extend beyond monoaminergic dysfunction and may involve dysregulation of the HPA axis, neuroinflammation, impaired neuroplasticity, and disruption of the gut-brain axis (GBA). Gut dysbiosis has been associated with treatment resistance through alterations in monoamine turnover, immune signalling, intestinal barrier integrity, and drug-microbiome interactions affecting antidepressant bioavailability. This review integrates emerging evidence supporting targeted modulation of the GBA as a mechanistically informed strategy for TRD. Specific microbial strains (e.g., Christensenella minuta, Akkermansia muciniphila, Bifidobacterium breve CCFM1025), microbial metabolites (e.g., indole-3-propionic acid, indole-3-lactic acid, anserine), and phytochemicals (e.g., curcumin, matrine, salidroside) are discussed for their proposed roles in modulating neuroendocrine signalling, neuroinflammation, and synaptic plasticity. The review also highlights emerging peripheral biomarkers, including the kynurenine/tryptophan ratio, serum metabolomics, and lymphocyte serotonin transporter clustering, as candidate tools for stratified psychiatry. Most of the evidence discussed in this review comes from animal studies, in vitro systems, and computational analyses, while direct evidence in patients with treatment-resistant depression remains limited. These findings provide important mechanistic insights into gut-brain axis dysfunction but require further validation in human TRD populations. Biomarker-guided and endotype-based approaches targeting the gut-brain axis may offer a useful framework for future research, although their clinical utility has yet to be established.\n\nID: 42561356\nTitle: Fructooligosaccharides modulate intestinal fermentation and immune response during Giardia lamblia infection in Meriones unguiculatus.\nAbstract: Giardia lamblia infection alters gut physiology and microbiota interactions, but the impact of prebiotic supplementation in this context remains unclear. This study investigated how fructooligosaccharide (FOS) treatment affects microbial fermentation, intestinal function, inflammation, and hepatic bile acid synthesis in G. lamblia-infected gerbils. Gerbils were divided into four groups: uninfected control, infected control, uninfected and FOS-treated, and infected and FOS-treated. Cecal short-chain fatty acids (SCFAs), intestinal disaccharidase activities, serum and intestinal cytokines, and hepatic expression of Cyp7a1 and Cyp8b1 were analysed. Giardia infection increased cecal acetate, reduced butyrate, elevated serum TNF-\u03b1, and increased hepatic Cyp7a1 expression. FOS supplementation increased cecal propionate and other SCFAs and elevated IL-10 levels in serum and intestinal tissue. Notably, FOS reduced intestinal maltase activity regardless of infection status, without affecting lactase activity. Together, these data indicate that giardiasis alters microbial fermentation and inflammatory responses, whereas FOS supplementation primarily promotes a more regulatory immune profile, characterized by increased IL-10 levels, alongside shifts in microbial fermentation, without directly modifying hepatic bile acid-related gene expression. These findings highlight complex diet-microbiota-host interactions during intestinal parasitic infection and support further mechanistic studies.\n\nID: 42560743\nTitle: The Vitamin D Receptor Story: Discovery, Control, and Genomic Reach.\nAbstract: The vitamin D receptor (VDR) is a ligand-activated nuclear receptor that mediates the biological actions of vitamin D and is a critical regulator of mineral homeostasis, cellular differentiation, immune function, and metabolism. VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis.\n\nID: 42560463\nTitle: Protective Effects of Double-layered Multinucleated Microcapsules Containing Bifidobacterium adolescentis FS2-3 Against Enteritis Mediated by Different Pathogens.\nAbstract: Bifidobacterium adolescentis (B. adolescentis), a dominant probiotic in the gut of infants and healthy adults, exerts protective effects on immune development and disease prevention. However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936. To improve its intestinal colonization efficiency, we constructed double-layered multinucleated microcapsules (probiotic microcapsules) of B. adolescentis FS2-3 and evaluated their effects on bacterial enteritis induced by five representative foodborne pathogens. The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1. These findings provide new insights into the application of probiotic microcapsules in the treatment of enteritis.\n\nID: 42570864\nTitle: Genome-scale modeling of the influence of microbiota-derived butyrate on the regulation of human metabolism by the histone deacetylase SIRT1.\nAbstract: Genome-scale metabolic models predict metabolic flux distributions but typically lack explicit transcriptional regulation, limiting their ability to simulate graded effects of epigenetic modulators such as Sirtuin1. To develop and validate a continuous regulatory-metabolic framework integrating Sirtuin T1-dependent transcriptional control into human genome-scale metabolism and to quantify the metabolic impact of microbiome-derived butyrate in intestinal epithelial cells. A curated Sirtuin1-centered regulatory network comprising 8 transcriptional regulators, 487 metabolic genes, and 2,296 reactions (\u223c22% of Recon3D) was integrated into the Recon3D reconstruction to generate iSirtuin1_HumanMet. Continuous regulatory logic was implemented within steady-state regulatory flux balance analysis. Tissue-specific models were derived from genotype-tissue expression transcriptomic data using FASTCORE. Human Caco-2 intestinal epithelial cells were treated with 0-9 mM sodium butyrate for 72 h. Sirtuin1 protein expression was quantified by Western blot and modeled using an inverse exponential regression (R2 = 0.669). Predicted maximal intracellular production capacities were compared with independent metabolomics data using Spearman correlation. Simulated Sirtuin1 activation (0.0-1.0) modulated 2,296 reactions, with 34.2% of upregulated reactions belonging to fatty acid oxidation. Increasing Sirtuin1 promoted gluconeogenesis and lipid utilization while repressing glycolysis and nucleotide interconversion. Tissue-specific simulations across 54 tissues revealed distinct clustering of metabolic responses. Incorporation of experimentally derived butyrate-Sirtuin1 inhibition resulted in concordant monotonic trends between predicted and measured intracellular metabolites for 11 of 13 metabolites (85%), with Spearman \u03c1 ranging from -0.64 to 0.94 (median \u03c1 \u2248 0.74). Integration of microbiome-predicted butyrate fluxes showed strong host metabolic associations, including correlations up to \u03c1 = -0.92 (p = 8.77 \u00d7 10-22). In Caco-2 intestinal epithelial cells and tissue-specific human metabolic models, continuous integration of Sirtuin1 regulation enables quantitative simulation of graded transcriptional control and microbiome-derived metabolic modulation, providing a systems-level framework to study diet-microbiome-host metabolic interactions.\n\nID: 42570481\nTitle: Lutein-loaded Pickering high internal phase emulsions stabilized by protein-polyphenol-polysaccharide self-assembled particles: Interfacial behavior, in vitro/in vivo stability and release.\nAbstract: This study aimed to encapsulate lutein in high internal phase emulsions (HIPEs) stabilized by quinoa protein isolate (QPI), tannic acid (TA), and high-methoxy pectin (HMP) particles at varying concentrations to address its low delivery efficiency and bioavailability. High concentrations (3%-4%) of QPI-TA-HMP particles demonstrated strong interfacial adsorption, forming thick viscoelastic films around oil droplets. These interfacial properties imparted controllable rheological behaviors, textural characteristics, and stable 3D-printing scaffolds to the lutein-loaded HIPEs, achieving an encapsulation efficiency of 81.65\u00a0\u00b1\u00a02.36%. In vitro tests indicated that HIPEs enhanced lutein's resistance to storage, heat, and UV exposure while facilitating sustained intestinal release, resulting in a lutein bioaccessibility of 43.73\u00a0\u00b1\u00a01.44%. In vivo experiments further demonstrated that the HIPEs delivery system maintained high lutein concentrations in the small intestine, cecum, and colon, thereby significantly enhancing lutein accumulation in systemic circulation. These findings provide new insights into enhancing lutein's stability, delivery performance, and bioavailability.\n\nID: 42570476\nTitle: Comprehensive characterization of walnut oil processing by-products: biochemical composition, bioactive properties, and polyphenol in vitro bioaccessibility and bioavailability.\nAbstract: Underutilized by-products from the walnut-oil industry, namely walnut oilcake (WOC) and walnut oil dregs (WOD), were evaluated for their nutritional composition, phenolic compound profile and digestive behaviour, as well as bioactive properties (antioxidant, antimicrobial, anti-inflammatory, cytotoxic and prebiotic activities). WOC was rich in protein (38.1\u00a0g/100\u00a0g) and dietary fiber (32.6\u00a0g/100\u00a0g), while WOD presented high fat (46.8\u00a0g/100\u00a0g) and carbohydrate content (20.9\u00a0g/100\u00a0g). Glansreginin A was the predominant phenolic compound in both matrices. Following in vitro digestion using the INFOGEST protocol, higher overall polyphenol bioaccessibility was noticed in WOD (78%) compared to WOC (15%). Bioaccessible fractions exhibited higher antioxidant activity than the undigested samples. Glansreginin A was detected only on the cellular apical compartment suggesting the absence of transport across Caco-2 cells. After in vitro digestion, the non-bioaccessible fractions enhanced the growth of Lactobacillus and Bifidobacterium strains, in some cases surpassing fructooligosaccharides, a standard prebiotic. These findings support the valorisation of walnut by-products as functional ingredients, also contributing to sustainable food systems.\n\nID: 42569490\nTitle: The metal-uptake-deficient Escherichia coli strain GR536 contains the \u03d580 prophage.\nAbstract: We report the genome sequence of Escherichia coli GR536, a previously constructed metal-uptake-deficient strain derived from E. coli W3110. Growth of GR536 in an iron-restricted liquid medium resulted in apparent lysis during the early exponential growth phase. This effect was exacerbated in cells transformed with pBAD30, a commonly used arabinose-inducible expression vector. Whole-genome sequencing confirmed the expected gene disruptions (entC, feoABC, mntH, zupT::cat and fecABCDE::kan). However, comparison to E. coli W3110 identified the presence of the \u03d580 prophage (46.16 kbp) and cryptic prophage CPZ-55 (6.763 kbp), as well as the absence of cryptic prophage e14 (15.193 kbp). We also identified 9 IS-element deletions, 3 IS-element insertions, 7 other deletions or insertions and 74 candidate individual nucleotide changes. The growth defect in GR536 correlated with lysis due to the production of \u03d580 virions as determined by the inability of isolated phage to infect an E. coli strain lacking the phage receptor (\u2206fhuA) and the BamHI digestion pattern of the purified phage DNA. We further determined that the \u03d580-dependent lysis in GR536 is exacerbated by the presence of the chloramphenicol- and kanamycin-resistance markers introduced during construction of GR536 and the pBAD30 plasmid multiple cloning site. Removal of the markers (E. coli GR536*) and disruption of the pBAD30 multiple cloning site generated a strain that showed a 104-fold reduction in \u03d580 production. Furthermore, construction of a W3110 lysogen containing the \u03d580 prophage and comparison with GR536* grown under the same conditions showed a ~104-fold higher level of phage production by the parent strain, indicating that phage-dependent lysis was not increased by the deletion of the metal-uptake genes and thus independent of iron availability. These observations clarify growth conditions that limit the effects of \u03d580-dependent lysis when using GR536 to identify metal-uptake genes by complementation, specifically, removal of the antibiotic resistance markers and the avoidance of using intact pBAD30 as a negative control.\n\nID: 42568574\nTitle: Marine nutraceuticals from Mexican Pacific Sargassum targeting oxidative stress and inflammation in age-related macular degeneration.\nAbstract: Age-related macular degeneration (AMD) is a multifactorial retinal neurodegenerative disease characterized by oxidative stress, chronic inflammation, retinal pigment epithelium (RPE) dysfunction, and progressive central vision loss. Marine-derived bioactive compounds from Mexican Pacific Sargassum species have emerged as promising nutraceutical candidates due to their antioxidant, anti-inflammatory, and cytoprotective properties. This narrative review critically examines the nutritional composition and pharmacologically relevant bioactive constituents of Mexican Pacific Sargassum, with emphasis on fucoxanthin, fucoidans, phlorotannins, and polyunsaturated fatty acids. Particular attention is given to their molecular mechanisms of action in AMD-related pathways, including modulation of oxidative stress, Nrf2/HO-1 signaling, NF-\u03baB-mediated inflammation, VEGF-associated angiogenesis, mitochondrial dysfunction, and apoptosis in retinal cells. Current evidence from preclinical retinal models suggests that these compounds may exert protective effects against AMD progression through multipronged regulation of redox and inflammatory pathways. Additionally, major translational challenges related to bioavailability, extraction standardization, safety, and the absence of AMD-specific clinical trials are critically discussed. Overall, Mexican Pacific Sargassum represents a promising yet underexplored source of marine bioactives with potential applications in the development of nutraceutical strategies targeting retinal degeneration and AMD.\n\nID: 42567908\nTitle: Vitamin D supplementation and bone health in post-menopausal women: a 24-month randomized controlled intervention with enhanced bioavailability formulations.\nAbstract: Postmenopausal osteoporosis is a major public health issue affecting over one billion people worldwide. However, limited evidence exists on how different formulations with enhanced bioavailability compare in clinical outcomes with one another, even if there is extensive research on vitamin D tablets. Post-menopausal women's bone mineral density (BMD), bone turnover markers, and fracture risk over a 24-month period were evaluated using regular cholecalciferol, micronized cholecalciferol, and liposomal vitamin D3 combined with calcium supplements. Using age and baseline 25-hydroxyvitamin D [25(OH)D] levels, 612 post-menopausal women (ages 50-75 years) with T-scores ranging from -1.5 to -2.5 on dual-energy X-ray absorptiometry (DXA) were randomly assigned to one of four groups: regular cholecalciferol (1200 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), micronized cholecalciferol (1200 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), liposomal vitamin D3 (800 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), or placebo (n\u2009=\u2009153). Other results were changes in femoral neck, lumbar spine, total hip bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), C-terminal telopeptide of type I collagen (CTX), serum 25(OH)D levels, and incidence of new fragility fractures. Mean serum 25(OH)D levels were substantially higher (p\u2009=\u20090.003) in the liposomal group (38.2\u2009\u00b1\u20097.5\u2009ng/mL) than those in the control cholecalciferol group (28.5\u2009\u00b1\u20096.8\u2009ng/mL). The liposomal vitamin D3 group exhibited somewhat higher femoral neck BMD (2.8% \u00b1 1.2%; p\u2009=\u20090.012) and lumbar spine BMD (2.8% \u00b1 1.2%; p\u2009=\u20090.008) enhancement than did the placebo group (1.1% \u00b1 0.9%). The liposomal form showed the highest ratio (2.4\u2009\u00b1\u20090.6 versus 1.8\u2009\u00b1\u20090.5 placebo; p\u2009=\u20090.001); hence, BSAP/CTX ratios were significantly better in all the active treatment groups. Eight patients (5.2%) in the placebo group had fresh fragility fractures; two (1.3%), three (2.0%), and one (0.7%) in the conventional, micronized, and liposomal groups, respectively; \u03c7\u00b2 = 7.42; p\u2009=\u20090.059. Greater success in raising bone mineral density and lowering indicators of bone turnover with recent bioavailability-enhanced vitamin D3 formulas was observed in post-menopausal women, especially those on liposomal delivery systems. These results suggest that public health guidelines and clinical practice have to take into account a rather important element impacting the efficacy of vitamin D supplements: formulation technology. ClinicalTrials.gov identifier: NCT04987654.\n\nID: 42567243\nTitle: Comparative study of lipidic and polymeric nanoparticles encapsulating Benznidazole in an acute mice model of Chagas disease.\nAbstract: Chagas disease is a neglected infectious disease endemic to Latin America. Only two approved medications are available, benznidazole (BNZ) and nifurtimox, and both have suboptimal efficacy in the chronic stage of the disease and severe side effects. To overcome these limitations, we previously described the development of a lipid nanoformulation of BNZ (NLC-BNZ). Here, we extended this work to polymeric nanoparticles (EU-BNZ) and evaluated both in vivo for pharmacokinetics (PK) and efficacy. At the highest concentration tested, nanoencapsulation notably reduced BNZ cytotoxicity in CHO cells (from 50% to 100% viability). No significant differences were found in the PK profiles between the formulations and the free drug, orally administered at doses equivalent to 30 mg/kg of BNZ. In the mouse model of acute T. cruzi infection, treatment with NLC-BNZ and EU-BNZ improved survival relative to controls (empty carriers or vehicle) but was not superior to free BNZ. Consistent with the in vitro observations, mice treated with NLC showed a higher survival percentage compared to their polymeric counterparts. This finding highlights lipidic nanoparticles not merely as carriers but as potential therapeutic agents. Our findings provide a promising starting point for the exploration of lipidic compounds with potential intrinsic antiparasitic properties.\n\nID: 42566869\nTitle: Legume-based selenium bioavailability for crop and human nutrition: A global meta-analysis.\nAbstract: Selenium (Se) plays an important role in plant growth and human nutrition, and its narrow safety margin can cause adverse effects in the legume-based food system. A comprehensive insight is required to understand the precise use of Se to legumes for sustainable agriculture production and biofortification. We conducted a meta-analysis of 1644 pair-wise observations published from 2009 to 2024 and analyzed data by machine learning models (RF, XGBoost, and SVM). Effects of Se fertilizer type, concentration, exposure duration, application method, and growth medium on legume growth and physiology were evaluated. Se application at \u2264\u202f2.5\u202fmg\u202fkg-1 improved shoot dry weight, biological yield, chlorophyll content, and antioxidant enzymes (SOD, POD, CAT, and APX), while reducing oxidative stress related indicators such as H2O2. In contrast, elevated Se levels (>2.5\u202fmg\u202fkg-1) reduced yield, germination, disrupted antioxidant defenses, and increased oxidative damage. Se accumulation in legume grains exhibited an exposure-medium dependent response, with the highest accumulation observed under hydroponic conditions, followed by soil applications. Machine learning confirmed Se concentration, fertilizer type, and exposure matrix as dominant drivers of Se impact on legumes. Overall, precise Se application rate \u2264\u202f2.5\u202fmg\u202fkg-1 improves legume performance and supports sustainable legume-based agroecosystem management globally.\n\nID: 42563436\nTitle: DASH Diet, Dietary Nitrate, and Nitric Oxide Bioavailability: Implications for Endothelial Dysfunction and Hypertension in Older Adults.\nAbstract: Hypertension in the elderly is closely associated with vascular aging, characterized by endothelial dysfunction (ED) and a progressive decline in nitric oxide (NO) bioavailability. Age-related dysfunction of endothelial nitric oxide synthase (eNOS), compounded by increased oxidative stress, creates a vicious cycle of oxidative-nitrosative imbalance, leading to chronic inflammation and arterial stiffness. The Dietary Approaches to Stop Hypertension (DASH) diet was developed as a primary intervention to restore NO balance by protecting endogenous pathways and supplying alternative nitrate-nitrite-NO precursors. However, its cardiovascular benefits are often diminished by age-related alterations in nitrate metabolism and the extensive use of multiple medications in the elderly. Thus, while restoring balance remains a key therapeutic goal, future clinical strategies must evolve from broad dietary recommendations to more personalized, precise nutritional approaches, considering the unique physiological and pharmacological challenges faced by older adults.\n\nID: 42562482\nTitle: Benchmarking a 16S rRNA sequencing protocol for microbiome analysis in low-moisture grain environments.\nAbstract: Microbial amplicon sequencing studies are an important tool in food and biomedical research. However, accurate interpretation of the 16S rRNA gene survey requires specialized software and an algorithm to convert raw sequencing data into reliable taxonomic profiles. Given the existence of multiple bioinformatics pipelines varying in sequence aggregation strategies, reference databases, and filtering parameters, there is little to no consensus on best practices for LMF processing systems. In this study, we systematically assessed discrepancies in taxonomic composition, alpha diversity, and beta diversity across 32 combinations of bioinformatics workflows, based on eight widely used 16S rRNA pipelines and four taxonomic databases, applied to 16S rRNA gene sequences extracted from wheat milling environments (n\u00a0=\u00a0160). Weighted composite scores were used to select the top 10-performing workflow combinations for downstream analysis. Taxonomic assignments were broadly similar across workflows at the family and genus levels; however, genus-level diversity metrics were more sensitive to workflow choice. At the family level, diversity metrics were conserved across pipeline-database combinations (Chao1: 22.97\u00a0\u00b1\u00a02.20-24.92\u00a0\u00b1\u00a02.04; Shannon: 2.59\u00a0\u00b1\u00a00.19-2.74\u00a0\u00b1\u00a00.18; InvSimpson: 10.63\u00a0\u00b1\u00a01.25-11.27\u00a0\u00b1\u00a01.06; Bray-Curtis: 0.528-0.556; Jaccard: 0.557-0.582), whereas at the genus level both alpha and beta diversity exhibited wider ranges and larger dispersion (Chao1: 45.27\u00a0\u00b1\u00a05.68-50.20\u00a0\u00b1\u00a05.64; Shannon: 2.54\u00a0\u00b1\u00a00.24-2.73\u00a0\u00b1\u00a00.22; InvSimpson: 10.37\u00a0\u00b1\u00a01.4-11.03\u00a0\u00b1\u00a01.05; Bray-Curtis: 0.79-0.82; Jaccard: 0.79-0.80). Furthermore, ASV vs. OTU workflows were comparable across the evaluated metrics; however, ASVs showed numerically higher values for some genus-level measures than OTUs because they can resolve variation down to the single-nucleotide level, thereby retaining low-abundance features important for LMF safety. This work paves the way toward using bioinformatics and 16S pipelines to characterize sparse, low-density, and uneven samples in low-moisture environments.\n\nID: 42562122\nTitle: Stoichiometric and Probabilistic Characterization of Se:Hg Interactions in Yellowfin Tuna for Iberian Consumers.\nAbstract: Mercury in tuna is routinely assessed against regulatory thresholds in isolation, an approach that disregards the biological antagonism between methylmercury and selenium central to Hg toxicity. We characterized Se and Hg concentrations in tuna (Thunnus albacares) integrating stoichiometric and probabilistic analyses to reframe Hg risk. [Se:Hg] and HBVSe values were uniformly protective across all samples, and Se and Hg accumulation were shown to be independent. A 2\u00d72 classification matrix, combining the EU regulatory Hg threshold (1.0 \u03bcg/g ww) with the [Se:Hg] stoichiometric threshold of 1, was applied to simultaneously assess regulatory compliance and selenoprotective status. All samples were in the protective quadrant, with Hg below the regulatory ceiling and Se in stoichiometric excess in every case. Monte Carlo simulations (n = 100,000) further demonstrated that tuna consumption contributes meaningfully to dietary Se adequacy for both Portuguese and Spanish adults. After correction for Hg-mediated Se sequestration (reducing theoretically bioavailable Se by a mean of 18.6%) median theoretically bioavailable Se intake remained at 25.0% and 14.4% of the Dietary Reference Value for Portugal and Spain, respectively. At typical Iberian consumption levels, tuna contributes meaningfully to dietary Se adequacy, with Se present in stoichiometric excess of Hg across all samples.\n\nID: 42560683\nTitle: Pharmacokinetics, Amino Acid Responses, and Short-Term Tolerability of Intravenous and Oral L-Citrulline in Healthy Neonatal Holstein Calves.\nAbstract: L-citrulline is a precursor for endogenous arginine synthesis, supporting nitric oxide production and urea cycle function, yet its pharmacokinetics in neonatal calves are unknown. This study characterized and compared the pharmacokinetics of L-citrulline after intravenous (IV) and oral (PO) administration in healthy neonatal Holstein calves and evaluated associated amino acid responses and short-term clinical and laboratory tolerability. Six healthy male calves (2-4\u2009weeks old) received a single 150\u2009mg/kg dose of L-citrulline as extemporaneously prepared 5% (w/v) IV and 10% (w/v) PO formulations in a randomized 2-period crossover design with a 7-day washout. Blood samples were collected pre-dose and up to 48\u2009h post-dose. Plasma amino acids were quantified by LC-MS/MS, and pharmacokinetic parameters were estimated using non-compartmental analysis. After IV administration, the highest observed total plasma L-citrulline concentration was detected at the first post-dose sampling time, 5\u2009min after bolus administration (Cpeak 2213\u2009\u00b1\u2009629\u2009\u03bcmol/L; range, 1329-2830\u2009\u03bcmol/L). After PO administration, Cmax was 1107\u2009\u00b1\u2009371\u2009\u03bcmol/L (range, 623-1478\u2009\u03bcmol/L), with a median Tmax of 60\u2009min (range, 45-120\u2009min). Baseline-corrected non-compartmental analysis yielded t1/2 values of 2.32\u2009\u00b1\u20090.79\u2009h after IV administration and 2.23\u2009\u00b1\u20090.60\u2009h after PO administration, with AUC0-\u221e values of 4130\u2009\u00b1\u2009558 and 3444\u2009\u00b1\u20091067\u2009\u03bcmol\u00b7h/L, respectively. Absolute oral bioavailability was 0.86\u2009\u00b1\u20090.32 (range, 0.52-1.28). Both routes increased plasma arginine (max +159% IV; +122% PO) and ornithine (max +132% IV; +149% PO) with no clinically relevant adverse effects or laboratory abnormalities during short-term monitoring of clinical, hematological, biochemical, blood gas/electrolyte, and coagulation variables. These findings support further evaluation of L-citrulline as a nutritional and/or therapeutic supplement in neonatal calves.\n\nID: 42558392\nTitle: Neuroprotective role of Lactiplantibacillus plantarum C10-derived SCFAs: a functional food approach targeting gut-brain-axis disruption in rotenone-induced Parkinson's disease in-vivo in adult zebrafish.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuronal degeneration, oxidative stress, neuroinflammation, and gut microbiota dysbiosis. Increasing evidence highlights the role of the gut-brain axis (GBA) and probiotic-derived short-chain fatty acids (SCFAs) in modulating neuroinflammation and disease progression. This study investigated the neuroprotective potential of SCFAs produced by Lactiplantibacillus plantarum C10 in a rotenone-induced PD zebrafish model. SCFA-producing lactic acid bacteria were isolated from traditionally fermented cabbage (sauerkraut), and the most promising isolate was identified as L. plantarum C10 using morphological, biochemical, phylogenetic, and 16S rRNA gene sequencing analyses. Fermentation conditions were optimized to maximize SCFA production, and the metabolites were characterized using Fourier-transform infrared spectroscopy (FTIR) and high-performance liquid chromatography (HPLC). Antioxidant activity was evaluated using DPPH and ABTS assays. Developmental toxicity was assessed in zebrafish embryos, followed by therapeutic evaluation in rotenone-induced adult zebrafish through behavioural, biochemical, molecular, and histopathological analyses. L. plantarum C10 exhibited strong probiotic characteristics, including antimicrobial activity, acid and bile tolerance, homofermentative metabolism, and extracellular polysaccharide production. Optimized fermentation significantly enhanced SCFA-associated metabolite production, while FTIR and HPLC confirmed the presence of fermentation-derived organic acid metabolites. The metabolites demonstrated potent antioxidant activity and showed minimal developmental toxicity up to 30 mg/mL in zebrafish embryos. In the rotenone-induced PD model, C10-derived SCFAs restored antioxidant enzyme activities, reduced oxidative stress, improved locomotor and cognitive performance, modulated genes associated with neuronal function, inflammation, the NRF2 signalling pathway, intestinal barrier integrity, and gut microbiota, and preserved normal brain and intestinal histoarchitecture. These findings demonstrate that L. plantarum C10-derived SCFA metabolites exert antioxidant, anti-inflammatory, and neuroprotective effects through modulation of the gut-brain axis. This study highlights the potential of probiotic-derived SCFAs as functional food-based therapeutic candidates for managing Parkinson's disease and associated gut dysbiosis.\n\nID: 42558378\nTitle: Extracellular vesicles from pasteurized Akkermansia muciniphila ameliorate inflammatory bowel disease through suppression of STING-driven inflammatory signaling.\nAbstract: Akkermansia muciniphila (A. muciniphila) has shown considerable potential in maintaining intestinal barrier homeostasis and regulating host inflammatory responses, both of which are commonly disrupted in inflammatory bowel disease (IBD). However, the therapeutic application of live A. muciniphila in IBD remains controversial. Interestingly, A. muciniphila-derived extracellular vesicles (AEVs) have been reported to improve intestinal barrier function, immune status, and gut microbiota composition, and may exert superior efficacy in IBD. In parallel, pasteurized A. muciniphila has been shown to retain, or even enhance, beneficial bioactivity compared with the live bacterium in certain disease settings. Here, we investigated whether extracellular vesicles derived from pasteurized A. muciniphila (PAEVs) preserve or further enhance the anti-inflammatory and barrier-protective effects of the parental bacterium. A dextran sulfate sodium (DSS)-induced mouse model of colitis was used to evaluate the therapeutic effects of PAEVs and AEVs. Disease severity, body weight loss, colonic histopathology, inflammatory cytokine expression, intestinal barrier integrity, inflammatory signaling pathways, and gut microbiota composition were assessed. PAEVs markedly attenuated DSS-induced colitis, as evidenced by reduced weight loss, improved colonic histology, decreased levels of TNF-\u03b1, IL-6, and IFN-\u03b3, and enhanced tight junction proteins. By contrast, AEVs improved only limited parameters, including Occludin expression and TNF-\u03b1 levels. Mechanistically, PAEV-mediated protection may be associated with suppression of the STING/I\u03baB/NF-\u03baB signaling axis and remodeling of the gut microbiota. These findings indicate that PAEVs effectively alleviate experimental IBD by enhancing tight junction proteins, suppressing some inflammatory cytokines, and modulating gut microbiota composition. Compared with AEVs, PAEVs exhibit broader protective effects, suggesting that extracellular vesicles derived from pasteurized A. muciniphila may represent a promising postbiotic strategy for IBD intervention. Importantly, this study offers the first systematic comparison of extracellular vesicles derived from live and pasteurized A. muciniphila, highlighting PAEVs as a distinct and potentially more effective postbiotic vesicle formulation for IBD intervention.\n\nID: 42558320\nTitle: Fermentable fiber supplementation in pigs promotes anti-parasitic defense mechanisms and impacts parasite growth in Ascaris suum infection.\nAbstract: Ascarids are among the most prevalent soil-transmitted helminths affecting both humans and livestock, particularly pigs. While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels.\n\nID: 42558218\nTitle: Development and validation of a nomogram for identifying prevalent sarcopenia in Chinese patients with Cardiovascular-Kidney-Metabolic Syndrome.\nAbstract: Sarcopenia is recognized as a significant comorbidity in patients with Cardiovascular-Kidney-Metabolic (CKM) Syndrome, yet validated prediction models for this population remain lacking. This study aimed to develop and validate a nomogram for predicting sarcopenia risk in Chinese patients with CKM syndrome. Data were derived from the China Health and Retirement Longitudinal Study (CHARLS) and an independent hospital dataset. The CHARLS 2015 dataset was split into a training set and an internal validation set; the CHARLS 2011 dataset served as the external validation set; and inpatients from Guangdong Provincial Hospital of Chinese Medicine constituted the hospital validation set. Sarcopenia was diagnosed according to the 2025 Asian Working Group for Sarcopenia criteria. Least absolute shrinkage and selection operator (LASSO) regression combined with multivariable logistic regression was used for predictor selection and model development. Model performance was evaluated by discrimination, calibration, and decision curve analysis (DCA). Nine predictors were identified: age, smoking status, high-density lipoprotein cholesterol, triglycerides, uric acid, C-reactive protein, hemoglobin, chronic obstructive pulmonary disease, and chronic liver disease. The model achieved area under the curve values of 0.817, 0.808, 0.800, and 0.834 in the training, internal validation, external validation, and hospital validation sets, respectively. Calibration was satisfactory in development cohorts (p\u202f>\u202f0.05), with some calibration drift in external populations. DCA confirmed clinical utility across all datasets. The developed nomogram incorporating nine accessible predictors demonstrated robust discrimination and clinical applicability for sarcopenia risk assessment in Chinese CKM patients, supporting its use in early screening and individualized intervention.\n\nID: 42558149\nTitle: Multi-omics analysis identifies a hepatocyte-associated signature in alcohol-related liver injury.\nAbstract: Alcohol-related liver disease (ALD) is a major cause of liver-related morbidity and mortality worldwide, yet the associations linking alcohol-induced gut microbial alterations to metabolic remodeling and hepatocyte dysfunction remain incompletely understood. Here, we applied an integrative multi-omics strategy combining untargeted fecal metabolomics, shotgun metagenomics, mouse liver bulk RNA sequencing, and reanalysis of publicly available human hepatic single-cell and bulk transcriptomic datasets to characterize alcohol exposure-associated gut-liver immunometabolic features. In a mouse model of acute ethanol-induced liver injury, fecal metabolomic and metagenomic profiling revealed marked alterations in microbial functional potential and fecal metabolic composition, identifying six convergent metabolic pathways across fecal multi-omics layers, including nucleotide metabolism, the pentose phosphate pathway, histidine metabolism, glycerophospholipid metabolism, glycine/serine/threonine metabolism, and the phosphotransferase system. Reanalysis of human ALD single-cell transcriptomes showed hepatocyte-enriched activity patterns for several corresponding pathways, suggesting potential pathway-level associations between fecal metabolic alterations and hepatic transcriptional responses. Integrative transcriptomic analysis further identified a ten-gene hepatocyte-associated signature, comprising LRG1, ORM1, ORM2, TAT, HP, FGB, FGG, ITIH3, NNMT, and AGT, which was associated with pathway activity and showed consistent upregulation across acute ethanol-induced liver injury and human ALD/AH transcriptomic datasets. In an external human cohort, this signature stratified patients into exploratory molecular subgroups with distinct metabolic pathway activities and clinical outcome distributions. Collectively, these findings provide a hypothesis-generating multi-omics framework for investigating alcohol-related liver injury and support further validation in chronic ethanol exposure models and functional studies.\n\nID: 42556887\nTitle: Microbiota, fermentation, and metabolite biotransformation: Pathways to functional foods and personalised nutrition.\nAbstract: Fermentation is among the oldest biotechnological processes and a modern platform for precision metabolic engineering, enabling the targeted production of health-promoting metabolites. The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition. This chapter explores the mechanistic links between microbial metabolism and host health, reviews emerging fermentation technologies for targeted metabolite production, and highlights industrial case studies demonstrating the transition of precision fermentation from research to commercial applications.\n\nID: 42556881\nTitle: Methodological approaches to assess protein digestibility with an emphasis on plant-derived foods.\nAbstract: The shift towards sustainable diets has increased interest in plant-based proteins and meat alternatives. The quality of protein depends on the content and digestibility of indispensable amino acids, which are shaped by molecular structure, food matrix interactions and processing. These factors influence amino acid bioavailability, digestion rates and metabolic outcomes. This work provides an overview of protein digestion, highlighting the influence of amino acid sequence, folding, \u03b2-sheet prevalence, disulfide crosslinking, aggregation and interactions with anti-nutritional factors on enzymatic accessibility and hydrolysis. Particular attention is given to plant-derived proteins and meat analogues, the digestibility of which is often modulated by intrinsic structural characteristics and complex matrix effects. Food processing has a dual effect, as mild treatments enhance proteolysis through unfolding and improved solubility, whereas harsh treatments cause aggregation, cross-linking, racemization and modifications that hinder enzyme access. This chapter covers\u00a0in vitro digestion models, including the standardized static INFOGEST model, as well as semi-dynamic, and dynamic models. It details their uses, advantages and disadvantages for evaluating protein digestibility and nutritional value. Advanced tools such as high-resolution mass spectrometry and peptidomics help to characterized digestion products and offer a better understanding of how hydrolysis influences functionality and safety implications. The chapter also addresses protein quality metrics such as Digestible Indispensable Amino Acid Score, the challenges associated with them, and the need for a comprehensive framework to assess the nutritional and health impacts of alternative and novel plant proteins.\n\nID: 42556880\nTitle: Pectins and modified pectins: Bridging food technology and human health innovations.\nAbstract: Pectins are a family of plant polysaccharides with complex structures whose significance extends beyond their established function as food texture modifiers. These compounds are directly relevant to human health, and their impact is influenced by structural diversity. The chemical composition of pectins varies according to botanical origin and is shaped by extraction and modification processes. Such structural differences determine both technological functionality and a range of bioactive properties, establishing pectins as potent dietary fibers with systemic health effects. Modified pectins exhibit immunomodulatory and anticancer activities through mechanisms including receptor interactions and modulation of key signaling pathways. In vivo studies further demonstrate their roles in regulating metabolism and in supporting gut barrier integrity. A critical aspect of pectin bioactivity involves promoting symbiotic interactions within the gut microbiota, increasing microbial diversity, and stimulating the production of beneficial metabolites, including short-chain fatty acids. Translational research, including clinical trials, has confirmed practical benefits for gastrointestinal management and metabolic health, and has highlighted the utility of pectins as adjuvants in pharmaceutical and nutritional formulations. This chapter highlights the link between pectins and the intersection of food science, nutrition, and biomedicine, emphasizing their potential as multifunctional ingredients for innovative health strategies.\n\nID: 42556236\nTitle: Protein digestibility and iron bioaccessibility of plant-based meat analogues.\nAbstract: Understanding the nutritional quality of plant-based meat alternatives (PBMAs) is important for consumers, manufacturers, and health professionals. This study examined nine commercial PBMAs, focusing on protein digestibility and iron dialyzability. In vitro protein digestibility ranged from 81 to 96%, comparable to meat (86-90%), and was highest in protein concentrates and isolates (97-99%). Extrusion conditions (150-750\u00a0rpm, 100-160\u00a0\u00b0C) had minimal impact on digestibility but significantly affected texture and sensory properties. Dialysable iron in PBMAs was lower (2-5%) than in fungi-based products (15-32%) and meat (2-40%), though PBMAs had higher total iron content. Iron fortification using ferrous citrate, fumarate, sulphate and ferric pyrophosphate yielded dialysable iron values of 1.9-3.4%. These findings provide valuable insights into the nutritional composition of PBMAs and highlight opportunities to optimize processing for improved iron bioavailability.\n\nID: 42555464\nTitle: Barnyard millet (Echinochloa species): an underutilized nutritional powerhouse with emerging nutraceutical benefits.\nAbstract: The impact of climate change presents an opportunity for orphan crops like millet to contribute to sustainable food systems. A prime example of an orphan crop with special traits and the potential to develop climate-smart agriculture is Barnyard millet (BYM). Alkaloids, steroids, polysaccharides, glycosides, tannins, phenols, dietary lignans and flavonoids are just a few of the antioxidants that are abundant in BYM. BYM's antioxidant potential, prebiotic status, anti-inflammatory, hypoglycemic, antibacterial and anticancerous properties help it to combat a myriad of diseases. The antinutritional compounds present in BYM such phytic acid, tannins, polyphenols, and amylase inhibitors limit the absorption of minerals because they form complexes with dietary minerals like calcium, zinc, magnesium, and iron and make them inaccessible for absorption. Various processing methods like dehulling, soaking, heating, gamma irradiation, cold plasma processing, fermentation might enhance the nutritional and technological functional qualities of BYM. The bioactives in BYM can improve their bioavailability, in vitro digestibility, efficiency, structural modification and stability by biological processing techniques such as germination and fermentation employing microbial strains. BYM straw's high cellulose and hemicellulose percentage makes C5 and C6 sugars accessible for bioconversion into bioethanol.\n\nID: 42555099\nTitle: Designing liposomal oral formulations aligned with physiology, payload properties, and scalable manufacturing.\nAbstract: Liposomes have long been established as versatile and biocompatible carriers for biologically active molecules. Advances in manufacturing technology have dramatically broadened their application landscape, positioning them today as effective platforms for the oral delivery of pharmacologically active compounds, nutrients, and dietary supplements. Developing effective oral liposomal formulations, however, demands more than empirical optimization. It requires a strategy that simultaneously accounts for the complex physiological environment of the gastrointestinal (GI) tract, the physicochemical profile of the encapsulated payload, and the practical realities of scalable production. This work presents an integrative framework that unifies four critical decision-making axes: the Biopharmaceutics Classification System (BCS), Lipinski's Rule of Five, log\u2009P assessment and production process constraints. By mapping BCS categories onto specific GI absorption mechanisms, this framework enables the rational engineering of liposome architecture and properties to actively exploit physiological uptake routes. If the approach is effectively applied, liposomal carriers can achieve bioavailability enhancement that is to some degree independent of the payload's intrinsic membrane permeability and markedly less susceptible to food-effect interference compared to conventional oral formulations. Critically, aligning payload BCS class and log\u2009P with manufacturing feasibility supports the rational selection of production methods and excipient systems, striking a calibrated balance among encapsulation efficiency, release kinetics, physicochemical stability, and scale-up practicality. The power of this integrated approach is illustrated through two contrasting compounds, vitamin C (highly hydrophilic, BCS Class I) and vitamin D (highly hydrophobic, BCS Class IV), representing opposite ends of the physicochemical spectrum. These case studies demonstrate that tailoring liposome composition and processing conditions to the specific payload profile and GI physiological context can yield meaningful, nutritionally relevant gains in oral bioavailability for both hydrophilic and lipophilic molecules. This framework provides a scientifically rigorous and industrially actionable foundation for the rational development of next-generation oral liposomal formulations, systems that are not only mechanistically optimized but also commercially viable, ultimately contributing to improved therapeutic and nutritional health outcomes.\n\nID: 42554711\nTitle: A survey of selected packaged food products in T\u00fcrkiye for listed ingredients containing phosphorus-based food additives.\nAbstract: This study aimed to determine the prevalence of phosphorus (P)-based additives in processed foods and beverages in the Turkish market and evaluate how these components are declared on ingredient labels. Ingredient lists of 3,293 products across 16 food categories from eight major retail chains and one online market operating across T\u00fcrkiye were systematically screened for phosphorus-based additives between January and April 2025. Data collected included food category, additive type (E number/name), total additive count, and declaration methods of phosphorus-based additives. P-based additives were identified in 58.3% of products. The highest prevalence was observed in cereal products (91.4%), ice creams (82.5%), and coffee and chocolate drinks (79.6%). Fourteen different P-based additives were detected, with lecithin (E 322, 39.9%), phosphate-containing modified starches (20.5%), and diphosphates (E 450, 18.8%) being the most common. Riboflavin-5'-phosphate was frequently found in snacks, while ammonium phosphatide was prominent in confectionery, cereal products, and ice creams. Declaration by name only (35.8%) was nearly twice as common as declaration by E number (18.2%). The prevalence of P-based additives in processed foods in T\u00fcrkiye exceeds global averages. The widespread presence of highly bioavailable inorganic phosphates and 'hidden' sources such as modified starch and lecithin, combined with complex labelling practices, may pose risks, particularly for individuals with renal disease. Improved labelling policies are warranted to support public health.\n\nID: 42554471\nTitle: Metagenome-assembled genomes of papillomaviruses from mallard and northern pintail cloacal swabs.\nAbstract: There is little known about papillomavirus diversity in waterfowl. From cloacal swabs of one mallard and three northern pintails sampled in New Mexico (USA), we identified four papillomavirus genomes. These papillomaviruses share >92.7% genome-wide nucleotide pairwise identity with Anas platyrhynchos papillomavirus 3 (AplaPV3) identified from a mallard in Missouri (USA).\n\nID: 42554132\nTitle: Characterizing the Milk Microbiome in Subclinical Mastitis: A Pilot 16S rRNA-Based Study in Cattle and Water Buffalo.\nAbstract: In the dairy sector of Bangladesh, subclinical mastitis (SCM) is a substantial and frequently undiagnosed challenge, with reported prevalence rates of 60%-77% in cattle and approximately 52% in buffaloes. Due to its complex characteristics and progressive development, efficient diagnosis and management are essential for enhancing dairy productivity. This pilot study employed 16S rRNA amplicon sequencing using Oxford Nanopore's MinION to investigate the milk microbiota of healthy and mastitic cattle and buffalo. A total of 423 clustered nucleotide sequences were identified in the samples, indicating significant taxonomic diversity: 11 phyla, 26 classes, 58 orders, 120 families and 272 genera. Distinct phylum-level patterns were observed, with Firmicutes predominating in healthy milk and a relative increase in Proteobacteria and Actinobacteriota in mastitic samples. At the genus level, Streptococcus and Lactococcus were predominant in mastitic samples, whereas Staphylococcus and Lactococcus were more prevalent in healthy milk. The results indicate that although overall microbial diversity was relatively consistent across groups, mastitis correlated with alterations in bacterial community composition, with notable differences between cattle and buffalo. This study suggests a potential association between SCM and microbial shifts; however, microbiome profiling cannot yet be recommended for diagnostic application. Clinical applicability requires validation in large-scale studies with individual-level sampling.\n\nID: 42554025\nTitle: High Methoxyl Pectin Consistently Reduces \u03b2-Carotene Bioaccessibility Across Various Gastrointestinal Digestion Conditions.\nAbstract: Dietary fiber could inhibit \u03b2-carotene bioaccessibility by restricting its release from the food matrix, interfering with digestive enzyme activities, binding bile salts, or modifying viscosity and other physicochemical properties of the digesta. In this study, we investigated whether high methoxyl pectin (HMP), a soluble dietary fiber found in fruits/vegetables and an additive for the food industry would impact \u03b2-carotene bioaccessibility under various physiological digestive conditions, following the INFOGEST gastrointestinal model. Concentrations of pancreatin plus bile salts and shear forces (simulated by varying water bath rounds/min. and glass bead addition) were modified in the presence (1.15\u00a0mg/mL digesta) and absence of HMP. Endpoints measured in the digesta included \u03b2-carotene bioaccessibility, surface tension, viscosity, micelle size, zeta potential, and triglyceride lipolysis. Adding HMP reduced overall bioaccessibility of \u03b2-carotene from 32.1\u00b16.2% to 24.1\u00b15.7% (p<0.001). All other parameters also had a significant impact on the bioaccessibility of \u03b2-carotene, that is, bile/pancreatin concentration (p<0.001), water bath shaking speed (p<0.001), and glass beads (p\u00a0=\u00a00.001). Surface tension, viscosity, and micelle size were less strongly affected by HMP addition (p<0.05), though not triglyceride lipolysis. The inhibitory effect of HMP varied depending on bile/pancreatin concentration and shear-forces, with strongest reductions when \u03b2-carotene bioaccessibility was highest at onset.\n\nID: 42552538\nTitle: Yiqi Huoxue Jiedu formula protects against sepsis-associated lung injury by modulating macrophage mitophagy and mtDNA-STING signaling.\nAbstract: Yiqi Huoxue Jiedu Formula (YHJF) is a traditional Chinese medicine formula that has been used as an adjunctive therapy for sepsis for nearly two decades. Previous clinical studies showed that YHJF improves Sequential Organ Failure Assessment (SOFA) scores and modulates gut microbiota in elderly patients with pneumonia-associated sepsis. However, the mechanism by which YHJF protects against sepsis-associated acute lung injury (SALI) remains unclear. A murine SALI model was established by cecal ligation and puncture (CLP). Therapeutic effects were evaluated by histopathology, micro-CT, pulmonary function assessment, and ELISA. Mechanistic studies included proteomic analysis of lung tissues and LPS-stimulated MH-S macrophages, pharmacological modulation with Mdivi-1 and urolithin A (UA), macrophage-epithelial co-culture, HPLC fingerprinting, UPLC-HRMS, and molecular docking. YHJF significantly improved 7-day survival and ameliorated lung injury, pulmonary edema, respiratory dysfunction, and systemic inflammation in mice with CLP-induced SALI. Proteomic profiling and subsequent functional assays suggested that enhanced mitophagy in macrophages represents a central protective mechanism. In vivo, YHJF increased autophagosome formation and PINK1/Parkin co-localization in BALF-derived alveolar macrophages. In vitro, YHJF restored mitochondrial homeostasis by activating PINK1/Parkin-dependent mitophagy in macrophages. This was accompanied by reduced cytoplasmic mtDNA leakage, downregulated cGAS expression, and suppression of the STING-TBK1-IRF3 pathway and subsequent type I interferon responses. Pharmacological inhibition of mitophagy with Mdivi-1 abolished these protective effects of YHJF, whereas activation with UA augmented them, demonstrating that mitophagy is necessary for YHJF-mediated protection. In a macrophage-epithelial co-culture system, YHJF-treated macrophages alleviated LPS-induced apoptosis in MLE-12 alveolar epithelial cells. Furthermore, chemical analysis integrated with molecular docking identified aloe-emodin, rhein, and genistein as candidate bioactive constituents of YHJF that likely contribute to its regulation of macrophage mitophagy. YHJF protects against SALI by restoring macrophage mitophagy and suppressing mtDNA-STING-mediated inflammatory signalling. These findings support YHJF as a potential therapeutic strategy for sepsis-associated lung injury.\n\nID: 42552537\nTitle: Chemotherapy-driven gut microbiota remodeling in ovarian cancer: a prospective longitudinal study.\nAbstract: The gut microbiome shapes chemotherapy efficacy and outcomes in several cancers, but evidence in ovarian cancer (OC) remains limited and largely cross-sectional. Despite high initial response rates, long-term relapse in OC remains frequent, while conventional markers capture only short-term therapeutic sensitivity. Whether longitudinal gut-microbiome trajectories during chemotherapy are associated with long-term recurrence remains unknown. Within the prospective SOCFCP cohort (N\u2009=\u200991; 13 recurrences), 100 serial fecal samples from a 33-patient sub-cohort were analyzed by 16S rRNA sequencing across the early, middle and late chemotherapy phases. Microbial successional trajectories and their association with recurrence were assessed by linear mixed-effects modeling, multivariable MaAsLin3 and repeated-measures correlation (rmcorr) networks, alongside stratified and covariate-adjusted sensitivity analyses and patient-level bootstrap assessment. The cumulative severe-toxicity-recurrence relationship was estimated by Firth penalized-likelihood regression, suited to sparse, separation-prone events. Microbial \u03b1-diversity rose progressively across the chemotherapy course (Shannon time effect p\u2009=\u20090.002), consistent with ecological succession, with higher turnover among peripheral than in core taxa (p\u2009=\u20090.005). Cumulative severe toxicity was not associated with recurrence (Firth OR\u2009=\u20090.99, 95% CI 0.68-1.39). Crucially, recurrent patients exhibited a progressive depletion of Fusicatenibacter (recurrence\u2009\u00d7\u2009time coefficient\u2009=\u2009-5.35, q\u2009<\u20090.001) that persisted across all sensitivity analyses-stratified, medication-adjusted, antibiotic-depleted and clinically-adjusted models (coefficient -4.60 to -5.66, all q\u2009<\u20090.001). PICRUSt2-based functional inference identified recurrence-associated differences in predicted de novo nucleotide-biosynthesis and cell-wall-assembly pathway abundance (q\u2009<\u20090.05). A bootstrap-supported co-variation network further linked specific taxa, notably Escherichia-Shigella and Roseburia, to these recurrence-associated pathways. Chemotherapy-driven gut-microbiome remodeling, in particular the recurrence-associated depletion of Fusicatenibacter, was associated with long-term OC relapse, whereas cumulative severe toxicity showed no significant association with recurrence. These longitudinal microbial dynamics support a candidate non-invasive marker that warrants external validation, and provide a hypothesis-generating rationale for testing whether targeting specific predicted bacterial functional pathways can modulate the host anti-tumor milieu.\n\nID: 42549852\nTitle: Dynamic Changes in Airway Microbiota and Immune Homeostasis in Patients With COPD and the Implications for Nursing Management.\nAbstract: To investigate changes in airway microbiota and immune markers across Chronic Obstructive Pulmonary Disease (COPD) stages and their associations with clinical phenotypes and nursing factors, providing a basis for precision nursing. 284 stable COPD patients (GOLD 2-3) were enrolled. Sputum and clinical data were collected at baseline (T0), exacerbation (T1), and recovery (T2). Microbiota structure was analyzed via 16S rRNA sequencing, and levels of immune markers such as interleukin-8 (IL-8) and IL-1\u03b2 were measured by Enzyme-Linked Immunosorbent Assay (ELISA). Statistical analysis was performed by integrating clinical scale scores and nursing adherence data. At T1, airway microbial \u03b1 diversity was remarkably lower than at T0 and T2 (p < 0.01). The relative abundances of Haemophilus and Prevotella increased, while those of Veillonella and Lactococcus decreased (p < 0.01). Levels of IL 8, IL 1\u03b2, and TNF \u03b1 were elevated, and Secretory Leukocyte Protease Inhibitor (SLPI) levels were reduced at T1 (p < 0.01). Notable correlations were found between microbiota and immune markers (e.g., Haemophilus abundance with IL 8 levels, r = 0.52, p < 0.01), and these were positively associated with clinical scores such as COPD Assessment Test (CAT) and St. George's Respiratory Questionnaire (SGRQ) (p < 0.05). Patients with >80% inhaler adherence and regular breathing exercises/nutrition had higher microbial diversity and attenuated inflammation (p<0.05). The airway microbiota-immune axis in COPD patients demonstrates a disease stage-dependent imbalance, characterized by microbial dysbiosis and enhanced pro-inflammatory responses during acute exacerbation. Good nursing adherence can modulate this axis's homeostasis, offering novel targets for precision nursing.\n\nID: 42548046\nTitle: Luteolin as a urease inhibitor: A novel therapeutic strategy against Helicobacter pylori.\nAbstract: The rising prevalence of antibiotic-resistant Helicobacter pylori (H. pylori) underscores the urgent need for alternative treatment strategies. By producing ammonia to neutralize gastric acid, the key virulence factor urease is essential for H. pylori acid tolerance, thereby representing a promising therapeutic target. In this study, we identified luteolin as a potent urease inhibitor (IC50\u2009=\u200930.50\u2009\u03bcg/mL) from a screening of over 200 natural compounds. Further investigation through molecular docking, dynamics simulations, cellular thermal shift assay, and enzyme kinetics studies confirmed its competitive binding to the Ni2+-centered catalytic site of H. pylori urease (HPU). Luteolin exhibited potent anti-H. pylori activity under standard and simulated gastric conditions, and showed low propensity for resistance development over 14 serial passages. Proteomic and metabolomic analyses revealed that luteolin inhibited HPU activity, and the consequent ammonia restriction triggered severe metabolic dysfunction, characterized by disruptions in nucleotide, amino acid biosynthesis and TCA cycle. In GES-1 cells, luteolin protected against H. pylori-induced damage. In a mouse model of H. pylori-induced peptic ulcer, luteolin treatment significantly reduced the bacterial load, with concomitant alleviation of gastric mucosal pathology and suppression of inflammatory responses. In contrast to antibiotic-induced gastric microbial dysbiosis, microbial diversity analysis indicated that luteolin treatment had minimal impact on the resident gastric microbiota. In summary, as a urease inhibitor, luteolin suppresses H. pylori by blocking ammonia production, thereby disrupting acid neutralization and inducing metabolic dysfunction, which collectively alleviates gastric damage and inflammation while minimizing microbiota disruption and resistance risk.\n\nID: 42544408\nTitle: Vitamin B deficiency and sarcopenia: an integrated narrative review of metabolic, inflammatory, endoplasmic reticulum stress, and myokine signaling pathways.\nAbstract: Sarcopenia is an age-related skeletal muscle disorder characterized by progressive decline in muscle mass, strength, and physical performance, leading to frailty, disability, falls, and increased mortality. Although its pathogenesis is multifactorial, growing evidence indicates that vitamin B complex deficiency contributes to muscle deterioration through interconnected metabolic and signaling pathways. This narrative review summarizes current evidence regarding the roles of B vitamins in skeletal muscle biology and their potential contribution to sarcopenia. Vitamin B deficiency impairs mitochondrial energy metabolism by reducing cofactor availability and adenosine triphosphate production, thereby increasing oxidative stress and chronic inflammation. These disturbances may trigger endoplasmic reticulum stress and the integrated stress response, leading to activating transcription factor 4 (ATF4)-dependent induction of growth differentiation factor 15 (GDF15) and fibroblast growth factor 21 (FGF21) expression. Collectively, these changes disrupt protein homeostasis, suppress anabolic signaling, impair neuromuscular function, and alter myokine secretion by reducing anabolic mediators while increasing catabolic and inflammatory myokines, thereby accelerating muscle loss and functional decline. Current evidence is the strongest for vitamins B6, B9, and B12, whereas mechanistic and clinical data for B2, B3, B5, and B7 remain limited. Overall, vitamin B deficiency can be viewed as a modifiable biological contributor to sarcopenia. Well-designed prospective studies and randomized clinical trials are required to clarify causality, validate biomarkers, and determine whether targeted vitamin B supplementation can enhance exercise- and nutrition-based strategies for preserving muscle health in older adults.\n\nID: 42544154\nTitle: Causal Relationship Between Gut Microbiome and Infectious Mononucleosis: Bidirectional Mendelian Randomization Reveals Infectious Mononucleosis-Driven Gut Dysbiosis.\nAbstract: Background To assess bidirectionality between gut microbiota and Epstein-Barr virus (EBV)-driven infectious mononucleosis (IM), we conducted two-sample Mendelian randomization (MR). Given IM's heterogeneous symptoms and evidence linking microbiota to viral infection, this may inform novel prevention or treatment strategies. Methods We employed a bidirectional two-sample MR framework using summary data from 207 gut microbial taxa and 205 metabolic pathways (Dutch Microbiome Project, n = 7,738) and the FinnGen consortium. Causality was assessed via inverse variance weighting (IVW), MR-Egger, weighted median, and mode-based estimation. Statistical significance was set at P <0.05 (Bonferroni-corrected), with instruments validated by F-statistics >10. Heterogeneity and pleiotropy were evaluated using Cochran's Q, MR-Egger intercepts, and leave-one-out analyses. Results Forward MR: Several bacterial pathways and taxa were\u00a0positively associated with IM risk. These include the de novo purine nucleotide biosynthesis II superpathway (odds ratio (OR) = 1.246, 95% confidence interval (CI): 1.026-1.514, P = 0.027), anhydromuropeptide recycling (OR = 1.24, 95% CI: 1.014-1.517, P = 0.036), the superpathway of unsaturated fatty acid biosynthesis (Escherichia\u00a0coli) (OR = 1.194, 95% CI: 1.019-1.4, P = 0.028), Lactobacillaceae\u00a0(OR = 1.109, 95% CI: 1.02-1.206, P = 0.016), and Lactobacillus\u00a0(OR = 1.108, 95% CI: 1.017-1.207, P = 0.019). Conversely, several taxa and pathways exhibited protective effects. These include the glucose-1-phosphate degradation pathway (G1P-DP) (OR = 0.852, 95% CI: 0.731-0.994, P = 0.042), heme biosynthesis from glutamate (OR = 0.809, 95% CI: 0.676-0.969, P = 0.032), the superpathway of L-tyrosine biosynthesis (OR = 0.9, 95% CI: 0.811-0.998, P = 0.046), the flavin biosynthesis I pathway (OR = 0.817, 95% CI: 0.672-0.993, P = 0.042),\u00a0Streptococcaceae\u00a0(OR = 0.869, 95% CI: 0.779-0.968, P = 0.011), and\u00a0Streptococcus\u00a0(OR = 0.844, 95% CI: 0.731-0.937, P = 0.020). Reverse MR: IM was found to causally alter gut microbiome composition. IM was associated with a decrease\u00a0of beneficial genera such as Roseburia\u00a0(OR = 0.901, 95% CI: 0.837-0.982, P = 0.016) and Bacteroides ovatus\u00a0(OR = 0.915, 95% CI: 0.841-0.995, P = 0.038), as well as Streptococcus\u00a0(OR = 0.876, 95% CI: 0.775-0.991, P = 0.035). Conversely, IM increased the risk of enrichment for Prevotellaceae\u00a0(OR = 1.107, 95% CI: 1.016-1.210, P = 0.020) and Prevotella copri\u00a0(OR = 1.096, 95% CI: 1.000-1.200, P = 0.048). Regarding metabolic pathways, IM increased the risk of polyamine biosynthesis II (OR = 1.123, 95% CI: 1.016-1.243, P = 0.024), L-lysine biosynthesis II (OR = 1.094, 95% CI: 1.008-1.118, P = 0.031), and L-lysine biosynthesis VI (OR = 1.083, 95% CI: 1.000-1.172, P = 0.048), while showing a protective association with L-rhamnose degradation I (OR = 0.922, 95% CI: 0.851-0.999, P = 0.046). Conclusion This study provides genetic evidence of a bidirectional causal relationship between the gut microbiome and IM. These findings suggest that IM may influence gut microbial ecosystem structure, characterized by a reduction in beneficial symbionts (e.g., Roseburia) and an enrichment of potentially pro-inflammatory taxa (e.g., P.\u00a0copri). These findings may inform future microbiota-targeted interventions or risk stratification strategies for EBV-related diseases. Limitations include the European ancestry of study populations and the need for mechanistic validation.\n\nID: 42543651\nTitle: [Hematopoietic cell transplantation in the era of genome analysis].\nAbstract: Genomic information for hematologic malignancies is now routinely available in clinical practice, supporting the adaptation of hematopoietic cell transplantation, selection of conditioning intensity, and implementation of post-transplant maintenance therapy through refinement of disease risk assessment and minimal residual disease (MRD) measurement. This review presents the current evidence on the effective utilization of genomic information for acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), and myeloproliferative neoplasms (MPN). It also presents an up-to-date framework for optimal donor selection based on donor genome information, addressing both donor clonal hematopoiesis of indetermined significance and the risk that related donor candidates may carry the same hereditary predisposition. Finally, it discusses research showing that patient and donor genetic polymorphisms (SNPs) can predict transplant complications such as GVHD, and that reduced gut microbiota diversity, as detected by metagenomic analysis, impacts GVHD severity and survival. These examples illustrate the multifaceted role of genomic information in research efforts to improve hematopoietic cell transplantation outcomes.\n\nID: 42543328\nTitle: [Role of \"gut lung axis-NETs\" pathway in chronic obstructive pulmonary disease based on theory of \"deficiency, phlegm, stasis, and toxin\"].\nAbstract: Chronic obstructive pulmonary disease(COPD) is a systemic disease characterized by persistent airflow limitation and airway inflammation, with a consistently high incidence and a lack of effective clinical interventions to reverse disease progression. Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD.\n\nID: 42555569\nTitle: Monitoring radiation exposure through skin swab multi-omic profiling.\nAbstract: Exposure to ionizing radiation poses major health risks across medical, occupational, and spaceflight settings, driving the need for rapid, non-invasive biodosimetry tools. As the body's most accessible organ and the most frequent site of radiation injury, the skin represents a promising interface for monitoring exposure. Using colonized human skin equivalents (coHSE; 0 Gy n\u2009=\u20098, 1 Gy n\u2009=\u20096, 4 Gy n\u2009=\u20096) and mice (n\u2009=\u20096/group) models, we performed multi-omic profiling, integrating metabolomics, lipidomics, and metagenomics, on skin swab samples collected after exposure to 0, 1, or 4 Gy of x-rays. We identified two distinct metabolite panels: one discriminating irradiated from non-irradiated skin, and another distinguishing dose-specific response. These panels included conserved radiation-responsive metabolites (e.g., uric acid, xanthine, taurine) and skin-specific markers associated with barrier integrity (e.g., proline, arginine). Diacylglycerol network enrichment and shifts in radioprotective microbial taxa, including Lachnospiraceae and Lactobacillales, further supported a repair-driven molecular response. These data support the feasibility of skin swab signatures for non-invasive exposure classification, providing a molecular and microbial framework for skin based monitoring measure development and motivating validation in human cohorts for real-world biodosimetry.\n\nID: 42553399\nTitle: The role of the gut microbiota-uric acid metabolism axis in high-altitude hyperuricemia: dysregulation mechanisms, pathway associations and therapeutic perspectives.\nAbstract: High-altitude areas (\u22652500 m) are characterized by low oxygen concentrations, which leads more people affected by high uronic acid in the blood. This review systematically investigates the \"gut microbiota-uric acid metabolism axis\" as a potential target for inhibiting Hyperuricemia (HUA). This review introduces the four functions of the axis: direct reduction of uric acid, intestinal excretion, regulation of uricase expression, and the intestinal-renal axis signal; then investigates how hypoxia alters all of these paths. In addition, this review illustrates how this axis is related to the classical metabolic pathway of purine synthesis, renal excretion, lactate metabolism, inflammatory-oxidative stress and genetic susceptibility. Adaptation difference: Native highlanders and migrants show different degrees of adjustment to life in the mountains, and migrants are relatively more prone to axis dysfunction. Finally, this review introduces targeted intervention strategies, such as probiotics, prebiotics, fecal microbiota transplantation, and their combination with uric acid-lowering or anti-inflammatory drugs, and put forward a population-stratified precision intervention framework. Overall, this paper provides a theoretical foundation and novel direction for understanding and preventing plateau HUA.\n\nID: 42551765\nTitle: XANTHINE OXIDOREDUCTASE IN DIGESTIVE DISEASES: A CONTEXT-DEPENDENT REDOX SWITCH LINKING INFLAMMATION, METABOLISM AND CARCINOGENESIS.\nAbstract: Xanthine oxidoreductase (XOR) is a molybdenum-containing enzyme that catalyzes the final steps of purine catabolism, generating uric acid and, under specific conditions, reactive oxygen species (ROS) and reactive nitrogen species. Due to its high expression in the liver and gastrointestinal tract, XOR has emerged as an important regulator of redox homeostasis, innate immunity and metabolic adaptation in digestive diseases. This review examines the role of XOR in hepatic disorders, intestinal ischemia-reperfusion (I/R) injury and inflammatory bowel disease (IBD), focusing on oxidative stress, tissue injury, host-microbiome interactions and carcinogenesis. Evidence indicates increased XOR activity in inflammatory and fibrotic liver diseases, where ROS generation contributes to hepatocellular damage, fibrosis and disease progression. In intestinal I/R injury, XOR links ATP depletion and hypoxanthine accumulation to reperfusion-associated oxidative stress, barrier dysfunction, bacterial translocation and systemic inflammation. In IBD, XOR participates in cytokine amplification, redox imbalance, thiopurine metabolism and inflammation-associated colorectal carcinogenesis. Emerging evidence also supports bidirectional interactions between XOR/urate metabolism and the gut microbiota, suggesting a broader role for XOR in regulating intestinal immune homeostasis. However, the biological significance of XOR is strongly context dependent. Whereas increased XOR activity promotes inflammatory tissue injury, advanced gastrointestinal malignancies are frequently characterized by reduced XOR expression, loss of cellular differentiation and enhanced de novo purine synthesis. Overall, XOR emerges as a central, but highly plastic, regulator at the interface between metabolism, inflammation and host-microbiome interactions in digestive diseases. Its clinical exploitation will depend on the ability to understand, rather than oversimplifying, this complexity.\n\nID: 42545610\nTitle: Comparative Assessment of Autochthonous Probiotic Lactic Acid Bacteria on Growth Performance, Blood Biochemistry, and Intestinal Microbiota of Broiler Chickens in C\u00f4te d'Ivoire.\nAbstract: Antimicrobial resistance is accelerating the search for sustainable alternatives to growth-promoting antibiotics (GPAs) in tropical poultry farming. The objective of this study was to evaluate three indigenous strains of lactic acid bacteria (LABs): Enterococcus faecium JK96, Pediococcus acidilactici JK148, and Lactobacillus pentosus JK151, isolated from the gastrointestinal tract of free-range, native Ivory Coast chickens, as probiotic candidates for commercial broiler production. To this end, in a 42-day completely randomized trial, 480 one-day-old Cobb 500 broiler chicks were divided into six treatment groups: three individual probiotic strains, a combination of several strains (1:1:1), an antibiotic growth promoter (Tylo-dox), and an untreated control group. Each group consisted of two pens of 40 chickens each. Freeze-dried probiotic powders (viable cell count: ~1.0\u2009\u00d7\u200910\u00b9\u2070 CFU/g) were administered daily in drinking water at a rate of 0.5\u00a0g per 10\u00a0L. Growth performance, blood biochemical parameters, and intestinal microbiota were assessed in 42-day-old chickens. The results of this study showed that probiotic supplementation significantly improved average daily gain (ADG) and feed conversion ratio (FCR) compared to the control and antibiotic-treated groups. The Lactobacillus pentosus JK151 strain achieved the highest ADG on day 28 (108.27\u00a0g/day vs. 83.83\u00a0g/day in the control group), maintained an FCR below 2.0 throughout the finishing period, and exhibited no cumulative mortality, compared to 5.0% in the antibiotic-treated group. No significant differences were observed in serum biochemical parameters (glucose, total protein, albumin, triglycerides, cholesterol, uric acid, alkaline phosphatase) or carcass characteristics between treatments (p\u2009>\u20090.05), thus confirming the physiological safety of all tested strains. All probiotic groups significantly reduced the intestinal bacterial load of Escherichia coli (1.38-9.54\u2009\u00d7\u200910\u2077 CFU/g) compared to the untreated control group (9.81\u2009\u00d7\u200910\u2079 CFU/g) and the antibiotic-treated group (1.10\u2009\u00d7\u200910\u2079 CFU/g), without significantly altering the total mesophilic aerobic flora or lactic acid bacteria populations. Notably, the antibiotic-treated group exhibited a higher bacterial load of E. coli than the control group, These results demonstrate that indigenous strains of lactic acid bacteria, in particular L. pentosus JK151, are effective, safe and locally adapted alternatives to growth-promoting antibiotics (GPAs) for sustainable broiler chicken production in C\u00f4te d'Ivoire.\n\nID: 42543271\nTitle: [Research progress on targeted regulation of inflammation-related signaling pathways by TCM for prevention and treatment of acute exacerbation of chronic obstructive pulmonary disease].\nAbstract: Acute exacerbation of chronic obstructive pulmonary disease(AECOPD) constitutes the acute deterioration phase of chronic obstructive pulmonary disease(COPD), typified by an abrupt intensification of respiratory symptomatology, encompassing exacerbated dyspnea, heightened cough severity, augmented sputum volume, and pronounced respiratory insufficiency. Systemic inflammatory cascades serve as a cardinal etiological driver of AECOPD, emanating from multifaceted host-pathogen interactions involving viral, bacterial, or polymicrobial infections, superimposed upon environmental modulators that collectively precipitate accelerated pathological progression. These contributory elements markedly escalate the inflammatory milieu within the small airways, surmounting endogenous anti-inflammatory safeguards, thereby precipitating airway epithelial barrier disruption, microvascular dilation, edema, and prolific immune cell infiltration, which in turn perpetuate an inflammatory amplification loop. Such mechanisms converge to synergistically impair pulmonary function and extend durations of inpatient care. Current therapeutic paradigms for AECOPD predominantly incorporate bronchodilators, anti-inflammatory pharmacotherapies, supplemental oxygen administration, and mechanical ventilatory support. Notwithstanding these interventions, persistent limitations include the adverse sequelae of protracted systemic glucocorticoid therapy, escalating antimicrobial resistance profiles, and ventilator-associated morbidities. Ergo, there exists an imperative to investigate novel therapeutic modalities that confer enhanced safety and efficacy. TCM proffers salient therapeutic merits via its multi-target and multi-pathway pharmacodynamics, facilitating regulation of pivotal signaling pathways, including the Toll-like receptor 4(TLR4)/nuclear factor-\u03baB(NF-\u03baB), NF-\u03baB/NOD-like receptor pyrin domain containing 3(NLRP3), phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), Janus kinase(JAK)/signal transducer and activator of transcription(STAT), and neutrophil elastase(NE)/mucin 5AC(MUC5AC) pathways. Through such regulatory interventions, TCM efficaciously attenuates inflammatory response, ameliorates symptomatic burden, and diminishes the incidence of AECOPD. The present investigation endeavors to delineate systematically the extant advancements in TCM-mediated regulation of inflammation-related signaling pathways within the context of AECOPD, thereby furnishing a robust theoretical framework and empirical guidance for optimized clinical interventions and pharmaceutical innovations in AECOPD management.\n\nID: 42532628\nTitle: Telomere dysfunction and mucociliary impairment drive idiopathic pulmonary fibrosis susceptibility: insights from a Sardinian whole-exome study.\nAbstract: Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease in which both environmental exposures and genetic predisposition contribute to disease susceptibility. Studying the burden of rare variants in a genetically homogeneous founder population may help identify disease-associated alleles that are difficult to detect in more heterogeneous populations. Whole exome sequencing was performed on 123 patients with IPF and 1110 unrelated controls from Sardinia (Italy). Variant prioritisations were conducted according to the American College of Medical Genetics (ACMG) guidelines. In parallel, gene burden of rare predicted loss-of-function variants was assessed using the Cohort Allelic Sums Test (CAST) algorithm to identify genes significantly enriched in IPF cases compared with controls. Pathogenic or likely pathogenic variants in known telomere-related genes were identified in 11.4% of patients. These variants were associated with younger age at diagnosis and a higher prevalence among never-smokers. CAST analysis identified a significant enrichment of loss-of-function variants in 82 genes, including MUC5B (OR=443.1, false discovery rate=3.7E-05), functionally related to cilium organisation and motility, with a significant overrepresentation of dynein-related genes. This study supports the contribution of telomere-related variants to IPF susceptibility and suggests a possible role for rare variants affecting mucociliary pathways. Together, these findings broaden the current understanding of IPF biology in this cohort. The distinctive genetic background of the Sardinian population may have facilitated the identification of rare or population-specific variants, underscoring the potential value of founder populations in complex disease genetics.\n\nID: 42530645\nTitle: Lacticaseibacillus paracasei Jlus66 ameliorates hyperuricemia by inhibiting xanthine oxidase activity, modulating uric acid transporter proteins and the gut microbiota.\nAbstract: A novel strain of Lacticaseibacillus paracasei Jlus66 was isolated from a traditional fermented dairy product known as \"Nai Geda\", and its role in hyperuricemia remains unclear. We constructed a mouse model using potassium oxonate (OXO) and a high-purine diet to examine the impacts of Jlus66 supplementation on hyperuricemia in vivo. The results revealed that Lacticaseibacillus paracasei Jlus66 intervention substantially lowered blood uric acid (UA) concentrations through suppressing xanthine oxidase (XOD) activity in the liver to reduce UA synthesis and modulating UA transport to enhance its renal excretion. Furthermore, Lacticaseibacillus paracasei Jlus66 supplementation increased short-chain fatty acids (SCFAs) in cecal samples, which might account for the reduced secretion of serum pro-inflammatory cytokines interleukin-6 (IL-6), interleukin-1\u03b2 (IL-1\u03b2), and tumor necrosis factor-\u03b1 (TNF-\u03b1). Lacticaseibacillus paracasei Jlus66 enhanced intestinal barrier function through upregulating tight junction proteins and reinstating gut microbiota homeostasis. In conclusion, Lacticaseibacillus paracasei Jlus66 may be a potential probiotic for the management of hyperuricemia through modulating gut microbiota, promoting UA excretion, and inhibiting UA synthesis.\n\nID: 42529078\nTitle: Dose Titration of Plant-Based Flavonoid Blend Supplementation on Performance, Digestibility, Gut Microbiome, Blood Biomarkers, and Meat Quality of Growing Rabbits.\nAbstract: Rabbit meat is increasingly valued for its high nutritional quality, driving growing interest in enhancing its production through phytobiotics like plant-based flavonoid blend (PFB). So, this study looked at how a PFB at different doses influences the performance, digestibility, gut microbiota, blood biomarkers, liver health, and meat quality of growing rabbits. Sixty rabbits (body weight 552.63\u2009\u00b1\u200913.44\u2009g) were assigned at random to five dietary groups, having twelve replicates per group. The rabbits were fed a basal diet as a total mixed ration having 17.02% crude protein and 11.60\u2009MJ metabolizable energy/kg dry matter (DM), supplemented with PFB (g/kg diet) at 0.0 (control), 0.20, 0.40, 0.60, and 0.80. Following a 2\u2009weeks adjustment period, the feeding trial was conducted for 5\u2009weeks. When the trial was over, rabbits were sacrificed to collect digesta, blood, and meat samples for further analysis. Supplementation with PFB at 0.60\u2009g/kg diet (range: 0.50-0.70\u2009g/kg) showed a better final body weight (p\u2009=\u20090.01), weight gain (p\u2009<\u20090.001), and feed conversion ratio (p\u2009<\u20090.001), while significantly improving DM, nitrogen-free extract (p\u2009<\u20090.001), and ether extract (p\u2009=\u20090.02) digestibility. Besides, supplementation with PFB presented a linear reduction in Escherichia coli (p\u2009=\u20090.003), accompanied by linear improvement in Lactobacillus spp. (p\u2009<\u20090.001) and serum high density lipoprotein-cholesterol (HDL-C; p\u2009=\u20090.001). Broken-line analysis indicated optimal PFB supplementation levels of 0.60, 0.47, and 0.60\u2009g/kg diet for E.\u2009coli, Lactobacillus spp., and HDL-C, respectively. However, feed intake, serum triglycerides, other cholesterols, total protein, albumin, globulin, and uric acid remained unchanged across the groups. Furthermore, supplementation with PFB with an estimated breakpoint of 0.55\u2009g PFB/kg of diet effectively (p\u2009\u2264\u20090.02) reduced serum liver enzymes (aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase) indicating better liver health. In addition, PFB supplementation linearly reduced meat ether extract content and improved meat redness (p\u2009<\u20090.001), with optimal responses at 0.58 and 0.60\u2009g/kg diet, respectively, while having no impacts on meat protein, ash, lightness, or yellowness. Therefore, dietary inclusion of PFB at 0.55\u2009g-0.60\u2009g per kg diet optimized growth performance through enhanced weight gain, feed efficiency, and nutrient digestibility, while favorably modulating cecum microbiome, serum cholesterol, liver enzyme activities, and ameliorated meat quality.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD.\n  --- END ACTUAL ABSTRACT FOR 42543328 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA).\" (Source: 42514077)\n- \"The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43 mg/g\" (Source: 42566139)\n- \"Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures.\" (Source: 42509267)\n- \"In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate.\" (Source: 42447972)\n- \"Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens.\" (Source: 42429666)\n- \"Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation.\" (Source: 42356278)\n- \"PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota.\" (Source: 42567355)\n- \"These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways.\" (Source: 42516368)\n- \"Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation.\" (Source: 42312862)\n- \"Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance.\" (Source: 42567420)\n- \"In vitro fermentation studies demonstrated that Q60E modulated gut microbiota by promoting beneficial genera (Lactobacillus, Lachnospira and Bifidobacterium) while suppressing pathogenic Fusobacterium.\" (Source: 42564885)\n- \"FM8 supplementation promoted weight gain without excessive adipogenesis, elevated leptin levels, and amplified sucrase, lactase, aminopeptidase, and lipase activities, outperforming conventional fermented milk.\" (Source: 42562527)\n- \"Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation.\" (Source: 42346391)\n- \"Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts.\" (Source: 42558320)\n- \"Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood.\" (Source: 42560743)\n- \"We explore the mechanisms by which dysbiosis of the gut microbiota contributes to anemia development, including disruptions in nutrient absorption and inflammatory responses.\" (Source: 42564065)\n- \"After in vitro digestion, the non-bioaccessible fractions enhanced the growth of Lactobacillus and Bifidobacterium strains, in some cases surpassing fructooligosaccharides, a standard prebiotic.\" (Source: 42570476)\n- \"Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1.\" (Source: 42560463)\n- \"The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange.

We constructed a mouse model using potassium oxonate (OXO) and a high-purine diet to examine the impacts of Jlus66 supplementation on hyperuricemia in vivo. The results revealed that Lacticaseibacillus paracasei Jlus66 intervention substantially lowered blood uric acid (UA) concentrations through suppressing xanthine oxidase (XOD) activity in the liver to reduce UA synthesis and modulating UA transport to enhance its renal excretion. Furthermore, Lacticaseibacillus paracasei Jlus66 supplementation increased short-chain fatty acids (SCFAs) in cecal samples, which might account for the reduced secretion of serum pro-inflammatory cytokines interleukin-6 (IL-6), interleukin-1\u03b2 (IL-1\u03b2), and tumor necrosis factor-\u03b1 (TNF-\u03b1). Lacticaseibacillus paracasei Jlus66 enhanced intestinal barrier function through upregulating tight junction proteins and reinstating gut microbiota homeostasis.

Evidence supports that the gut-lung axis is a bidirectional communication highway fueled by microbial metabolites. Fermented plant-derived materials and specific bacterial consortia can restructure the gut microbiota to produce beneficial metabolites (e.g., SCFAs), which in turn support pulmonary homeostasis. While *Akkermansia* is recognized for mucin degradation via specific sulfatases, the claim concerning nucleotide supplementation's role in hyperuricemia-related *Akkermansia* colonization remains an area requiring further direct clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe systemic nature of lung health and repair is intrinsically linked to the intestinal microbiome through the gut-lung axis.

Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA).\n\nMicrobial metabolites, particularly short-chain fatty acids (SCFAs), serve as pivotal signaling molecules delivered by the gut that shape the local respiratory environment. In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate. The structural complexity of plant matrices, when processed via fermentation, enhances their utility as carriers for beneficial bacteria and bioactive compounds. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43 mg/g.\n\nRegarding *Akkermansia muciniphila*, its role in maintaining intestinal homeostasis is well-documented, partially through the production of extracellular vesicles. PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Its colonization is further supported by complex enzymatic adaptations. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Bioavailability through Fermentation:** Fermentation acts as a biological \"pre-digestion\" step that degrades antinutritional factors (e.g., tannins and phytic acid), increasing the bioaccessibility of essential nutrients and potentially enhancing the stability of probiotic strains like *Lactobacillus*.\n*   **Extracellular Vesicle Superiority:** Evidence suggests that extracellular vesicles derived from pasteurized *Akkermansia* (PAEVs) may provide broader protective effects in IBD compared to live bacteria or standard vesicles (AEVs), highlighting a shift toward postbiotic strategies.\n*   **Targeted Urease Inhibition:** Novel compounds like luteolin act as competitive urease inhibitors against *Helicobacter pylori*, providing a mechanism for acid tolerance suppression without the broad-spectrum ecological damage caused by traditional antibiotics.\n*   **Metabolic Signaling Networks:** The cross-talk between the gut and host organs is not just limited to metabolites; it involves direct genomic-metabolic regulation, as demonstrated by models integrating Sirtuin1-dependent transcriptional control with butyrate fluxes.\n*   **Phase-Variable Colonization:** *Akkermansia* colonization is not static; it utilizes epigenetic switches (capsular phase variation) to adapt its ecological niche within the mucus layer, balancing planktonic and biofilm states.\n*   **Radioprotection via Bile Acids:** Flavonoids like Taxifolin can reshape the gut microbiota to promote specific bile acid production, which subsequently activates the FXR signaling axis to suppress radiation-induced inflammation.\n*   **Sex-Dimorphic Responses:** Some interventions, such as taurine supplementation for intestinal/cognitive resilience, exhibit sexually dimorphic immune responses, mandating a sex-stratified approach for future therapeutic development.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition. This chapter explores the mechanistic links between microbial metabolism and host health, reviews emerging fermentation technologies for targeted metabolite production, and highlights industrial case studies demonstrating the transition of precision fermentation from research to commercial applications."

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair."

Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health."

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease."

Co-formulation with Brassica rapa L. polysaccharide offers a promising strategy to enhance its functionality; however, the impact of different colloidal delivery systems on the encapsulation performance and subsequent biological fate of this mixture remains unclear. In this study, we systematically compared three spray-dried delivery platforms, including liposomes (LP-CP), sodium caseinate nanoparticles (SC-CP), and \u03b2-cyclodextrin inclusion complexes (CYC-CP), for encapsulating CP. Our results demonstrated that the carrier system critically determined encapsulation performance, with SC-CP exhibiting superior curcumin loading capacity (7.24%), curcumin thermal stability (82.87% retention at 95\u00a0\u00b0C), and favorable hygroscopicity profiles. Notably, SC-CP facilitated enhanced colonic accumulation in vivo, achieving a peak accumulation of 53.45% at 8\u00a0h post-gavage, representing a 15-fold increase compared to curcumin from unencapsulated CP. By integrating in vitro fermentation models with in vivo animal experiments and employing 16S rRNA sequencing alongside short-chain fatty acid (SCFA) analysis, we systematically elucidated the carrier-specific modulatory effects on the gut microbiota. In the in vitro fermentation system, SC-CP significantly promoted the production of acetate, propionate, and butyrate, while enriching butyrate-producing genera such as Lachnospiraceae_NK4A136_group. In the in vivo animal model, SC-CP intervention resulted in a 1.6-fold increase in cecal butyrate levels and a marked increase in the abundance of beneficial genera, including Akkermansia, demonstrating superior modulation of microbial community structure and metabolic function. Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology. This study provides a theoretical foundation for the rational selection of delivery systems to maximize the functional efficacy of bioactive ingredients in functional food applications."

Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems."

The gut-kidney axis has emerged as a key factor in cisplatin-induced AKI, with gut microbial imbalance contributing to inflammation and metabolic dysregulation. Astragalus polysaccharides (APS), the main bioactive constituents of Astragalus membranaceus, have shown potential in mitigating AKI, partly through modulation of the gut microbiota. Clinical sequencing data indicate that cisplatin treatment reduces short-chain fatty acid (SCFA)-producing bacteria (e.g., Faecalibacterium, Roseburia) and increases potentially pathogenic groups (e.g., Enterobacteriaceae), leading to alterations in SCFA, amino acid, and bile acid metabolism. This study integrates these findings with existing literature to propose a molecular-weight (Mw)-defined APS model targeting the gut-kidney axis. While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects. Advanced gut-targeted delivery systems are also discussed as strategies to enhance APS bioavailability and colonic targeting. Understanding these Mw-dependent mechanisms is critical for developing APS as a precise adjunct therapy to prevent cisplatin-induced AKI and improve patient outcomes."

Emerging evidence highlights the gut-lung axis as a potential therapeutic target, with probiotics proposed to modulate Th17-related inflammatory pathways. In this randomized, double-blind, placebo-controlled trial, 50 patients with mild-to-moderate COPD were enrolled; 44 completed the 8-week intervention (23 probiotics, 21 placebo). Participants received either a multistrain probiotic formulation or placebo. Outcomes included spirometry, COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and serum IL-6, IL-17, and TGF-\u03b2 levels. Probiotic supplementation significantly improved FEV1 and FVC within the intervention group, although between-group spirometric differences were not significant. IL-6 levels declined significantly following probiotic therapy, with a significantly greater reduction compared to placebo, whereas IL-17 and TGF-\u03b2 remained unchanged. CAT scores improved significantly in the probiotic group, exceeding the minimal clinically important difference and demonstrating a significant between-group effect. No significant change was observed in mMRC scores.

Its high morbidity and mortality have posed a substantial public health burden, with current symptomatic treatments exhibiting inadequate control and potential adverse effects. With advances in microecological research techniques, the critical role of microbial homeostasis in the oral cavity, lungs, and gut in respiratory health has become increasingly prominent, and microbial dysbiosis is closely associated with progression and therapeutic outcomes of COPD. This review summarizes the compositional alterations of oral, lung, and gut microbiota in COPD patients, analyzes the interactions of the oral-lung axis and gut-lung axis, and delineates three mechanisms through which microbial dysbiosis promotes COPD progression: pathogenic bacterial migration, abnormal metabolite production and immune dysregulation. Additionally, this review summarizes Western and traditional Chinese medicine interventions targeting microbiota homeostasis, including antibiotics, microecological preparations, and herbal medicines, which have shown potential in improving COPD clinical outcomes. This review aims to provide a theoretical reference for the clinical diagnosis and management of COPD. Millions of people worldwide live with chronic obstructive pulmonary disease (COPD), which brings persistent breathing struggles that disrupt their daily living. Current standard treatments mainly relieve symptoms, but have limited effects on controlling disease progression, and may cause unwanted side effects. Mounting research shows that microbes in the mouth, lungs and gut play a critical role in maintaining lung health, while their imbalance can drive COPD progression. This review focused on the link between microbial balance and COPD to find new intervention ideas. We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders. We also sorted out Western and traditional Chinese medicine strategies that restore microbial balance to improve COPD treatment and quality of life. These findings show a promising strategy for COPD therapy from the perspective of regulating microbial balance."

In its most serious manifestations, it can cause death by asphyxiation. Currently, no efficacious therapeutic interventions exist to avert or counteract these serious outcomes. Baicalein (BAI) is a core quality marker of the traditional Chinese medicine Scutellaria baicalensis, but the mechanism of its oral action remains unclear. Assess the therapeutic efficacy of BAI in AA mice models and investigate its mechanism of action. Evaluate the efficacy of BAI on ovalbumin-induced AA mice. To assess alterations in the pulmonary and gut microbial communities, 16S rRNA sequencing was employed. The integrity and restoration of the lung and intestinal epithelial lining were evaluated via immunohistochemistry. Furthermore, gas chromatography-mass spectrometry quantified fecal levels of short-chain fatty acids (SCFAs) in AA mice, and flow cytometry was used to analyze the content of ILC2 cells in colon tissue. Finally, the role of beneficial bacteria and their metabolites in inhibiting AA was further confirmed through fecal microbiota transplantation (FMT). Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins. Moreover, BAI mitigated colonic epithelial damage, inhibited ILC2s activation in the colon, enriched the abundance of gut probiotics capable of producing SCFAs, especially Akkermansia muciniphila (A. muciniphila), and increased the content of SCFAs such as propionic acid in feces. The FMT experiment conducted after gavage with broad-spectrum antibiotics confirmed that BAI mediated reversal of microbial dysbiosis plays a key role in the treatment of AA, significantly increasing the expression of GPR41 mRNA in colon tissue and inhibiting the activation of ILC2s. The potential prebiotic BAI mitigates AA via targeting A. muciniphila and its metabolites, which consequently inhibits epithelial damage and type 2 immune activation."

However, the dynamic interactions among pulmonary pathology, gut microbiota, and host metabolism during these episodes remains unclear. This study aimed to delineate the longitudinal characteristics of virus-induced AECOPD and identify potential biomarkers. Mice were exposed to cigarette smoke for eight weeks, followed by intranasal inoculation with IAV. A longitudinal assessment was conducted from day 1 to day 15 post-infection, integrating analyses of lung pathology, lung function, gut microbiome, and both serum and fecal metabolomes. Additionally, random forest modeling was employed to identify specific metabolic biomarkers associated with the acute exacerbation stage. Mice exposed to cigarette smoke and IAV exhibited significant pulmonary immune cell recruitment, impaired lung function, and emphysematous changes, peaking at day 5 post-infection. By day 15, acute airway inflammation had subsided; however, interstitial immune cell infiltration, collagen deposition, and emphysema persisted. 16S rRNA sequencing revealed dynamic shifts in gut microbiota composition, with the abundance of Intestinimonas positively correlating with pulmonary inflammatory markers. Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation. Random forest analysis identified 1-Methylnicotinamide (1-MNA) as a promising biomarker for distinguishing virus-triggered AECOPD, achieving an area under the curve (AUC) of 1.0. This study demonstrates that cigarette smoke combined with influenza infection induces persistent lung injury alongside concurrent disruption of intestinal flora and serum metabolism. The findings show that gut microbiota and metabolites are potential biomarkers and supplementation with unsaturated fatty acids may represent a novel therapeutic strategy for virus-induced AECOPD."

There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as milk may have fewer adverse effects associated with high-dose supplemental intake. Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation. Structural and functional manipulation of milk proteins, such as whey and lactoferrin, can also modify matrix functionality; for example, appropriate processing conditions can preserve lactoferrin's iron-binding capacity, supporting iron transport and bioavailability. Compared with plant-based milks, which often require fortification and extensive processing, the dairy milk matrix is particularly effective at promoting nutrient absorption.

While intestinal microbiota, particularly Akkermansia muciniphila (AKK), has been linked to the regulation of ALI in adult murine model, its impact on juvenile hosts, who exhibit heightened susceptibility to lipopolysaccharide (LPS)-induced ALI, remains poorly understood. Moreover, despite microencapsulation enhancing the probiotic gastrointestinal survival and colonization of probiotics, the therapeutic potential of microencapsulated AKK (AKK-MC) in juvenile murine ALI has not been explored. In this study, juvenile mice were orally gavaged with live AKK or AKK-MC for 14 days, with LPS-induced ALI established on day 11. Lung tissues were analyzed for morphological changes and inflammatory cytokine analysis. Bronchoalveolar lavage fluid (BALF) was collected for total cell counts and protein concentration. Macrophages and neutrophils infiltration in the lungs was quantified via immunofluorescence staining. Four segments of the intestinal tract (jejunum, ileum, cecum, and colon) were harvested for histological analysis using hematoxylin and eosin (H&E), Alcian blue-periodic acid-Schiff (AB-PAS), and toluidine blue (TBO) staining. These evaluations included measurements of villus height to crypt depth, intestinal injury scoring, and counts of goblet and mast cells. AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage. This was evidenced by reduced protein concentration and cell counts in BALF, downregulation of Tnf-\u03b1 and Il-1\u03b2 expression, improved lung histology, and decreased macrophage infiltration and neutrophil extracellular traps formation. In the intestine, AKK treatment restored mucosal architecture, increased villus height to crypt depth ratios, maintained goblet cell populations, and reduced mast cell infiltration across intestinal segments. These results demonstrate that microencapsulation enhances AKK's efficacy in ameliorating LPS-induced ALI in juvenile mice through gut microbiota modulation.

SARS-CoV-2 infection is known to disrupt the gut microbiome, but the downstream functional impacts on microbial metabolism and host immune responses remain insufficiently understood. Using K18-hACE2 transgenic mice, researchers investigated the effects of SARS-CoV-2 variants (WA and Omicron) on the gut microbiome and host immunity. Microbial composition and functional profiles were assessed post-infection. To test the therapeutic potential of Akkermansia muciniphila (A. muciniphila), live bacteria were administered prophylactically, and various outcomes were evaluated, including weight loss, lung pathology, immune cell phenotypes, and cytokine production. In K18-hACE2 transgenic mice infected with SARS-CoV-2, there was a marked reduction in gut microbial diversity, accompanied by a consistent enrichment of A. muciniphila. This microbial shift was associated with functional disruptions in key metabolic pathways, particularly those involved in glycosaminoglycan degradation and lipid metabolism, suggesting a broader impact of infection on microbial functionality. Remarkably, prophylactic administration of live A. muciniphila prior to infection led to significant protective effects. Treated mice exhibited reduced weight loss and improved lung histopathology compared to untreated controls. Local antiviral immune responses in the lung were notably enhanced without triggering excessive systemic inflammation. Mice receiving A. muciniphila also demonstrated elevated production of Th2 and Th17 cytokines, robust expansion of tissue-resident memory T cells, and the formation of inducible bronchus-associated lymphoid tissue (iBALT)-all indicative of potentiated mucosal immunity. These findings highlight a functional role for A. muciniphila not only as a microbial signature of COVID-19-associated dysbiosis but also as an active modulator of host immune responses during respiratory viral infections. These findings position A. muciniphila as both a biomarker of COVID-19-related gut dysbiosis and a potent live biotherapeutic candidate for respiratory infections. Its ability to enhance mucosal immune responses through gut-lung axis modulation highlights its promise in prophylactic strategies against viral respiratory diseases, including SARS-CoV-2."

Botanical matrices, when processed through fermentation, overcome limitations of poor bioavailability. \"Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects.\" The utilization of these food-based matrices acts as a delivery system, where \"Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites.\" *Akkermansia muciniphila* is central to this paradigm, as \"AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage.\" Further, the therapeutic impact of such interventions is often dependent on the matrix, as \"Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses.\" \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation enables the transformation of plant-derived phytochemicals into more bioavailable forms, such as aglycones, which are essential for systemic therapeutic efficacy.\n*   *Akkermansia muciniphila* plays a dual role in hyperuricemia and COPD, serving as both a biomarker of health and a therapeutic agent that supports barrier integrity.\n*   Colloidal delivery systems for bioactive compounds, such as curcumin, significantly influence their spatiotemporal accumulation in the gut and subsequent microbial modulation.\n*   The \"gut-lung axis\" is not merely an immunological pathway; it is a metabolic rheostat fueled by short-chain fatty acids (SCFAs) and tryptophan metabolites.\n*   Heat-inactivated *Akkermansia muciniphila* (postbiotics) exhibits therapeutic potential comparable to live bacteria in modulating uric acid metabolism and inflammatory pathways.\n*   Cisplatin-induced nephrotoxicity represents another systemic disease context where gut-kidney axis modulation via polysaccharides mimics gut-lung axis dynamics.\n*   The use of probiotics, such as *Lactobacillus* species, provides an adjunctive therapy to reduce emphysema and inflammation in COPD by restoring microbial diversity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition. This chapter explores the mechanistic links between microbial metabolism and host health, reviews emerging fermentation technologies for targeted metabolite production, and highlights industrial case studies demonstrating the transition of precision fermentation from research to commercial applications.\n\nID: 42554872\nTitle: Recombinant Amuc_1100 from Akkermansia muciniphila modulates tight junction-associated protein in vaginal epithelial cells.\nAbstract: Amuc_1100, an outer membrane protein of the mucin-degrading commensal bacterium Akkermansia muciniphila, is known to strengthen intestinal epithelial barrier integrity, with reports suggesting a potential involvement of Toll-like receptor 2 (TLR2). Its role in the vaginal epithelial barrier, however, remains unexplored. In this study, recombinant Amuc_1100 was expressed in a baculovirus-insect cell system and purified by immobilized metal affinity chromatography (IMAC). Purified Amuc_1100 exhibited concentration-dependent binding to recombinant TLR2 in ELISA. In VK2/E6E7 vaginal epithelial cells, Amuc_1100 treatment did not alter viability across the tested concentrations, confirming the absence of cytotoxicity. Western blot analysis demonstrated that Amuc_1100 treatment significantly increased the expression of tight junction-associated proteins, including Zonula Occludens-1 (ZO-1), Claudin-1 (CLDN-1), and Claudin-4 (CLDN-4), under basal conditions. Furthermore, stimulation with lipopolysaccharide (LPS) or zymosan A markedly reduced ZO-1 levels, whereas co-treatment with Amuc_1100 restored expression under both conditions. Collectively, these findings provide preliminary evidence that recombinant Amuc_1100 modulates tight junction-associated protein expression in vaginal epithelial cells. However, additional functional barrier assays, mechanistic studies, and in vivo validation are required to further evaluate its potential as a postbiotic candidate.\n\nID: 42543328\nTitle: [Role of \"gut lung axis-NETs\" pathway in chronic obstructive pulmonary disease based on theory of \"deficiency, phlegm, stasis, and toxin\"].\nAbstract: Chronic obstructive pulmonary disease(COPD) is a systemic disease characterized by persistent airflow limitation and airway inflammation, with a consistently high incidence and a lack of effective clinical interventions to reverse disease progression. Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD.\n\nID: 42528645\nTitle: Gut microbiota dysbiosis in COPD patients increases the level of queuine in the blood serum abnormally enhancing the viability of lung epithelial cells.\nAbstract: To investigate the association between gut-airway microbiota dysbiosis, serum queuine levels, and early malignant transformation in patients with chronic obstructive pulmonary disease (COPD). We further explored whether the potential mechanistic role of queuine in enhancing lung epithelial cell viability under cigarette smoke exposure. Stable COPD patients were stratified into a high relative abundance of Proteobacteria group (CH) and a low relative abundance of Proteobacteria group (CL) using 16S rRNA gene sequencing of fecal samples. Airway microbiota profiles were analyzed in parallel to assess gut-lung axis coupling. Serum queuine concentrations were quantified using LC-MS/MS in healthy controls, COPD subgroups (CL and CH), and COPD patients complicated by lung cancer. Clinical symptoms (CAT, mMRC, SCSS) and spirometry (FEV1/FVC, FEV1, FEV1% predicted, FVC, FEF25-75%) were assessed. In vitro experiments were performed using cigarette smoke extract (CSE)-stimulated lung cancer epithelial A549 cells and bronchial epithelial BEAS-2B cells to determine the effects of queuine on cell viability. Chest CT imaging was analyzed to quantify pulmonary nodules as an indicator of in vivo epithelial proliferative activity. The \u03b1-diversity of gut microbiota did not differ between CH and CL. In contrast, \u03b2-diversity showed separation (PERMANOVA P\u00a0=\u00a00.062), with CH characterized by Proteobacteria enrichment and relative depletion of Firmicutes, Bacteroidota, and Actinobacteriota. Airway communities showed concordant remodeling with shifts in taxa consistent with dysbiosis. Serum queuine concentrations increased stepwise from healthy controls to COPD, were higher in CH than CL, and were highest in COPD complicated by lung cancer. Despite comparable pulmonary function and symptom scores between CH and CL groups, the CH group exhibited a significantly higher number of pulmonary nodules on CT imaging, particularly ground-glass nodules. In vitro, queuine significantly enhanced the viability of CSE-stimulated A549 lung cancer cells but failed to rescue CSE-induced growth inhibition in BEAS-2B cells. COPD-associated gut microbiota dysbiosis, particularly enrichment of Proteobacteria, is closely associated with elevated systemic queuine levels. Excess queuine enhances cell viability of smoke-exposed lung cancer epithelial cells and is associated with increased pulmonary nodules in vivo. These findings identify queuine as a microbiota-derived metabolic mediator that may connect COPD-related dysbiosis to abnormal proliferation of lung epithelial cells.\n\nID: 42514077\nTitle: The Gut-Lung Microbiome Axis in Alveolar Stem Cell Regeneration and Lung Repair.\nAbstract: The mammalian respiratory system stands as a frontline barrier, constantly exposed to environmental insults, balancing defensive immunity with gas exchange. Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair.\n\nID: 42509759\nTitle: Mulberry, Gut Microbiota and Gut Functionality: Effects Shaped by Raw Material and Processing Methods.\nAbstract: Mulberry species (Morus spp.) provide phytochemically distinct plant materials in which leaves are typically characterized by high levels of iminosugars (notably 1-deoxynojirimycin), flavonols/flavones, and polysaccharides, whereas fruits-especially Morus nigra-contain substantial amounts of anthocyanins alongside other phenolic compounds and polysaccharides. Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health.\n\nID: 42501848\nTitle: Food peptides and the immune system: A review of their effects on macrophages, lymphocytes, and cytokine production.\nAbstract: Food-derived bioactive peptides (FDBPs) are short amino acid sequences encrypted within dietary proteins that can be released during digestion, food processing or fermentation and exert immunomodulatory effects. This review critically examines recent evidence on the interactions between FDBPs and the immune system, with particular emphasis on macrophages, lymphocytes, and cytokine production. Peptides derived from dairy, egg, marine, and plant proteins have been shown to influence key immune functions. In macrophages, FDBPs may enhance phagocytosis and proliferation, and modulate M1/M2 polarization. Their effects on cytokine production are highly context-dependent: in resting cells, many peptides stimulate pro-inflammatory mediators such as TNF-\u03b1, IL-6, and nitric oxide, whereas in activated macrophages they may suppress these same mediators and promote IL-10 expression. In lymphocytes, FDBPs can stimulate proliferation and influence CD4+ T-helper cell differentiation, often shifting responses away from Th2-mediated allergy-associated pathways towards Th1 and regulatory T-cell-mediated tolerance. These effects are linked to interactions with cell surface receptors, including TLRs and to modulation of intracellular NF-\u03baB and MAPK signaling pathways. This review also evaluates the methodological limitations in peptide generation, purification, and experimental modeling that contribute to inconsistent findings across studies. Finally, major knowledge gaps are identified, including the need for more human clinical trials, a deeper understanding of peptide bioavailability, and the role of the gut microbiota as a potential intermediary. Standardized, physiologically relevant models will be essential for translating the immunotherapeutic potential of FDBPs into practical applications.\n\nID: 42482463\nTitle: Multifaceted effects of galU deletion on phenotype and virulence of Pseudomonas aeruginosa in vitro and in vivo.\nAbstract: Pseudomonas aeruginosa is a widespread Gram-negative opportunistic pathogen in environmental and hospital settings, frequently causing respiratory diseases such as cystic fibrosis (CF), chronic obstructive pulmonary disorder (COPD), and ventilator-associated pneumonia. In our previous study, a galU-deleted clinical P. aeruginosa was found to exhibit increased susceptibility to polymyxins. The galU gene plays an important role in the biosynthesis of lipopolysaccharide (LPS) O-antigen. Here, we systematically evaluated the effects of galU deletion on the phenotype and virulence of P. aeruginosa PAO1. A galU deletion mutant was successfully constructed in P. aeruginosa PAO1 by CRISPR/Cas9, and the complementation was accomplished by pUCP18 plasmid carrying wild-type galU. The changes in phenotype, virulence, and pathogenicity were systemically studied. The results revealed that knockout of galU led to the loss of O-antigen, which affected growth, virulence, and pathogenicity through various ways in P. aeruginosa, and significantly affected the susceptibility of P. aeruginosa to polymyxins. Mechanism study suggested the involvements of quorum sensing, Entner-Doudoroff pathway, and tyrosine metabolism on bacterial virulence and antibiotic susceptibility changes after galU deletion. galU and the related pathways may serve as effective targets for the treatment of P. aeruginosa infection, providing a theoretical basis for the development of novel antibacterial drugs.\n\nID: 42444969\nTitle: Exercise-induced gut microbiota metabolites and the gut-lung axis: implications for chronic obstructive pulmonary disease.\nAbstract: Chronic obstructive pulmonary disease (COPD) is increasingly recognised as a systemic disorder associated with gut dysbiosis and impaired gutlung communication. COPD-associated gut dysbiosis suggests potential bidirectional interactions between the gut and lung, which may be mediated by circulating immune cells, gut microbiota-derived metabolites and systemic inflammatory mediators. Emerging evidence suggests that exercise may improve COPD-related symptoms and quality of life not only through direct cardiopulmonary adaptations but also by reshaping gut microbiota composition and metabolic function. Microbiota-derived metabolites, including short-chain fatty acids (SCFAs), secondary bile acids (SBAs) and indole derivatives, may act as key mediators linking exercise-induced microbial changes to pulmonary immune regulation, inflammatory signalling, oxidative stress and epithelial barrier integrity. However, current evidence remains fragmented, and the mechanisms by which exercise-responsive microbial metabolites influence COPD-related pulmonary inflammation, barrier dysfunction and immune homeostasis have not been fully clarified. This review synthesises evidence from human studies, animal models and mechanistic investigations to clarify the relationship among exercise, gut microbiota and COPD, with a focus on how exercise-responsive microbial metabolites may contribute to improved pulmonary health. By integrating current evidence within an exercise-gut-lung axis framework, this review provides a mechanistic basis for developing microbiota-targeted exercise strategies for COPD prevention and management.\n\nID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, \u03b2-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1\u03b1 signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.\n\nID: 42425354\nTitle: Natural chlorophyll\u2011sodium alginate oral hydrogel for robust treatment of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is a chronic and relapsing inflammatory bowel disorder that may lead to debilitating symptoms and serious complications such as toxic megacolon, intestinal perforation, and colon cancer. Conventional oral therapies are often limited by poor bioavailability and significant adverse effects. Herein, we developed an oral hydrogel for treatment of UC by electrostatic and hydrogen-bonding interactions of chlorophyll (Chl) and sodium alginate (SA) for the first time. The as-prepared Chl-SA hydrogel exhibited excellent biocompatibility and pH-responsive properties. In vitro assays showed that it reduced TNF-\u03b1 (271.51\u00a0pg/mL compared with 863.4\u00a0pg/mL in the LPS group), increased IL-10 (321.53\u00a0pg/mL compared with 91.66\u00a0pg/mL in the LPS group), and achieved 70% DPPH radical scavenging, confirming its potent anti-inflammatory and antioxidant activities. It exhibited robust therapeutic effects in a DSS-induced colitis mouse model after seven days of treatment, including ameliorating intestinal inflammation and restoring barrier integrity. These effects were achieved by mitigating oxidative stress, promoting mucosal healing and the expression of ZO-1 and occludin-1, as well as rebalancing the gut microbiota and restoring its richness and diversity. Importantly, given that hydrogels are generally known to offer advantages for patients with dysphagia over traditional oral formulations, the present study suggests that the Chl-SA hydrogel can offer therapeutic potential as a suitable oral dosage form for UC.\n\nID: 42424676\nTitle: Dark tea-derived exosome-like nanovesicles suppress hepatocellular carcinoma via inhibiting Akt pathway and modulating immune profiles.\nAbstract: Accumulating evidence indicates the microbial fermentation enhanced the health benefits and potential anti-tumor effect of dark tea. However, low bioavailability and unclarified therapeutic mechanisms impeded its deeply application. Plant-derived exosome-like nanoparticles offered a promising option for improving bioavailability and targeted delivery capability. To obtain dark tea-derived exosome-like nanovesicles (DTELNs) and clarify their material basis, investigate the therapeutic effects on hepatocyte carcinoma (HCC) and potential mechanisms. DTELNs were isolated by tangential flow filtration, TEM, NTA, nucleic acid & protein analysis system and LC-MS/MS were used to characterize their morphological characteristics and chemical composition. Orthotopic HCC model mice were established and employed for DTELNs' oral administration. Living imaging, H&E staining and biochemical assays were used to evaluate therapeutic effects. Untargeted metabolomic, 16S rRNA sequencing and cytometry by time-of-flight (CyTOF) were used to investigate the alteration of endogenous substances and immune features. Potential targets were explored by network pharmacology, protein-protein interaction, and verified by western blot. Finally, HCC patient-derived organoids were generated to evaluate the clinical applicability of DTELNs. DTELNs exhibited typical exosomal features, major components including flavonoids, phenolic acids, lipids, amino acids and their derivatives, and miRNAs. DTELNs markedly suppressed tumor proliferation, modulated gut microbial diversity, normalized liver-gut axis physiological homeostasis and enhanced immune responses. DTELNs distinctly downregulated the expressions of p-Akt, NF-\u03baB, Bcl-2, cyclin D1, upregulated the expressions of p-p53, PTEN, Bax, cleaved-caspase 3 and p21. DTELNs also exhibited potent inhibitory effect on HCC organoids. DTELNs demonstrated potent therapeutic efficacy against HCC. The mechanisms mainly involved directly modulating Akt-related signalling pathways, rebalancing gut microbiota and related metabolites, and further boosting anti-tumor immune responses.\n\nID: 42419400\nTitle: Preventive administration of ethanol extract of Atractylodes lancea (Thunb.) DC. attenuates Staphylococcus aureus-induced lung-gut injury in mice: explanatory pharmacological evidence related to its traditional dampness-resolving use.\nAbstract: Atractylodes lancea (Thunb.) DC. (A. lancea), a major botanical source of Atractylodis Rhizoma, has traditionally been used to dry dampness, strengthen the spleen, dispel wind-dampness, and regulate disorders associated with phlegm and impaired fluid transformation. However, the modern pharmacological basis linking these traditional indications to measurable lung-gut pathological changes remains insufficiently clarified. This study aimed to evaluate whether preventive administration of the ethanol extract of A. lancea (EEA) could attenuate Staphylococcus aureus-induced acute lung injury (ALI) in mice and to explore whether pulmonary edema, MUC5AC upregulation, intestinal barrier impairment, gut microbiota disturbance, and histidine metabolic remodeling may provide explanatory pharmacological evidence related to its traditional dampness-resolving and spleen-strengthening use. The chemical profile of EEA and its absorbed prototype constituents in plasma were characterized by UPLC-Triple TOF-MS/MS. Female BALB/c mice were orally administered EEA for 15 consecutive days and then challenged intranasally with Staphylococcus aureus. Lung injury, pulmonary edema, MUC5AC expression, inflammatory responses, MPO activity, hematological changes, intestinal barrier damage, and gut microbiota composition were evaluated using histopathological staining, lung wet/dry weight ratio, qRT-PCR, ELISA, blood cell analysis, and 16S rRNA sequencing. Untargeted metabolomics of serum and lung tissues, molecular docking, qRT-PCR validation of histidine metabolism-related genes, and correlation analysis were further performed to explore pathways associated with EEA intervention. A total of 29 compounds were identified in EEA, and six prototype constituents were detected in plasma after oral administration of EEA. Staphylococcus aureus challenge induced lung inflammatory injury characterized by increased lung index, elevated lung wet/dry weight ratio, inflammatory cell infiltration, pulmonary pathological damage, increased MUC5AC expression, increased IL-6 and TNF-\u03b1 levels, and decreased IL-10 levels. EEA attenuated these pulmonary abnormalities, reduced edema-related injury, decreased MUC5AC upregulation, and suppressed lung MPO activity. In parallel, EEA ameliorated intestinal pathological damage, restored mucin- and tight-junction-related gene expression, and partially modulated gut microbiota composition. Integrated serum and lung metabolomics consistently indicated that histidine metabolism was markedly perturbed in model mice and modulated by EEA intervention, as reflected by changes in L-histidine, histamine, N-methylhistamine, and methylimidazoleacetic acid. Molecular docking, qRT-PCR validation, and correlation analysis provided additional association-based evidence that histidine metabolic remodeling was correlated with the preventive effects of EEA. EEA attenuated Staphylococcus aureus-induced lung-gut inflammatory injury in mice, which was associated with its suppression of inflammatory responses, protection of intestinal barrier function, partial modulation of gut microbiota composition, and remodeling of histidine metabolism. These findings provide explanatory pharmacological evidence relevant to, rather than direct validation of, the traditional dampness-resolving and spleen-strengthening use of A. lancea.\n\nID: 42415755\nTitle: Probiotic-fermented herbal residues in obesity management: a review.\nAbstract: The global prevalence of has reached epidemic proportions, largely driven by dietary shifts toward high-calorie, processed foods, and sedentary lifestyles. Obesity is a complex polygenic disorder characterized by excessive adipose tissue accumulation and adipocyte hypertrophy, leading to various metabolic dysfunctions. The gut microbiota plays a pivotal role in regulating host energy metabolism, and dysbiosis, an imbalance in its composition and function, is strongly linked to obesity development and progression, Traditional Chinese medicine (TCM) has long been utilized for weight management, yet \"efficiency limitations\" and \"resource waste\" remain significant concerns. This comprehensive review explores the emerging approach of using probiotic-fermented herbal residues for obesity management. We examine how fermentation technologies transform herbal byproducts into high-value anti-obesity preparations through biological processes that enhance bioactive compounds, improve bioavailability, and modulate the gut-liver axis. The integration of herbal medicine with modern biotechnology impossible represents a promising frontier in sustainable healthcare and precision medicine for metabolic disorders.\n\nID: 42409563\nTitle: Effects of different processing methods on the nutritional components and in vitro digestion and fermentation characteristics of foxtail millet (Setaria italica).\nAbstract: Foxtail millet (Setaria italica) is highly nutritious but has limited consumer acceptance due to its taste and low nutrient bioavailability. Adopting different processing methods may increase the nutritional components and bioavailability of whole grains. However, no study has systematically compared the different processing methods. Therefore, we systematically compared seven processing methods (raw grain, ultrafine pulverization, steaming, ultrasound, extrusion puffing, early sprouting (24\u00a0h), and sprouting (84\u00a0h) to evaluate their effects on foxtail millet nutritional quality and gut microbiota fermentation. In vitro simulated digestion and human fecal fermentation models were used to assess the release of nutrients, digestibility, and microbial metabolic response. The best effects were achieved using sprouting (84\u00a0h), which significantly increased the polyphenol content, \u03b3-aminobutyric acid (GABA), and phenylalanine ammonia-lyase (PAL) activity. The digestion products had high concentrations of short-chain fatty acids (particularly propionate and butyrate) during fecal fermentation, indicating enhanced prebiotic potential. PAL activity transiently increased with extrusion puffing; however, effective GABA accumulation did not occur. Notably, the abundance of Proteobacteria increased with sprouting (84\u00a0h), suggesting a potential risk of opportunistic bacterial proliferation. Collectively, sprouting (84\u00a0h) is the optimal processing method for improving both the nutritional quality and prebiotic potential of foxtail millet, achieving primary nutrient enhancement and secondary metabolic regulation.\n\nID: 42404789\nTitle: Gut microbiota-mediated cardiovascular effects of Gastrodia elata polysaccharides: resolving the bioavailability-efficacy paradox.\nAbstract: Growing evidence suggests that many plant-derived polysaccharides exert systemic effects through gut microbiota-mediated mechanisms rather than direct absorption. Gastrodia elata polysaccharides (GEPs) represent a promising but mechanistically complex class of bioactive compounds with potential cardiovascular relevance. This review aims to examine the role of gut microbiota in mediating the biological effects of GEPs, with particular focus on resolving the bioavailability-efficacy paradox through host-microbe interactions. A narrative synthesis of recent literature was conducted, integrating data on microbiota-polysaccharide interactions, microbial fermentation processes, metabolite production, and downstream host signaling pathways. Due to limited systemic bioavailability, GEPs undergo extensive fermentation by gut microbiota, generating bioactive metabolites such as short-chain fatty acids and secondary bile acids. These metabolites modulate key host pathways including inflammation, oxidative stress, endothelial function, and lipid metabolism. Emerging evidence highlights the central role of the gut-heart axis in mediating these effects. The biological activity of GEPs is best understood within a microbiota-centered framework. This perspective provides new insights into polysaccharide pharmacology and supports the development of microbiome-targeted therapeutic strategies.\n\nID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17A+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.\n\nID: 42386309\nTitle: Air pollution-induced airway epithelial barrier dysfunction in COPD: a narrative review of mechanisms and therapeutic implications.\nAbstract: Air pollution is particularly harmful to people with chronic obstructive pulmonary disease (COPD). Exposure to air pollution from sources such as biomass burning leads to a unique COPD phenotype. This phenotype mainly shows airway damage, with less emphysema than typical smoking-related phenotypes. Across various COPD phenotypes, airway epithelial barrier dysfunction is a basic pathological mechanism. This narrative review summarises the current available evidence on how different types of airborne pollutants, including particulate matter (PM), ozone (O3), diesel exhaust and microplastics, damage the airway epithelial barrier. The toxicity of fine PM with a diameter of \u22642.5 \u00b5m, one of its main constituents, largely depends on its chemical composition. Some metals or organic chemicals with redox properties can initiate oxidation reactions and induce pathologic responses. The main injury mechanisms are direct physical damage to apical junctional complexes, serious impairment of mucociliary clearance and induction of oxidative stress. Apart from these immediate harms, pollutants also create epigenetic modifications and disturbed epithelium-immune cell cross-talk, which breaks down the equilibrium of the airway epithelial barrier. These system-wide effects are exacerbated through the gut-lung axis, which aggravates local lung damage via microbiome dysregulation. We evaluate emerging therapeutic strategies that aim to restore barrier integrity, including antioxidants, natural compounds, inhibitors directing specific pathways (e.g. epidermal growth factor receptor (EGFR), NLR family pyrin domain containing 3 (NLRP3)) and microbiome modulation via probiotics. Protection and repair of the airway epithelial barrier offer a promising approach to reducing the onset and progression of pollution-related COPD in populations vulnerable to highly polluted environments.\n\nID: 42370343\nTitle: Fermented garlic as a functional food strategy for malnutrition: microbial ecology, bioactive compounds, and clinical perspectives.\nAbstract: Fermented garlic (Allium sativum) represents a promising functional food with potential applications as a complementary nutritional intervention for malnourished populations. Through microbial fermentation and thermal processing two mechanistically distinct pathways, garlic undergoes significant biochemical transformations that enhance the availability of bioactive compounds, including S-allyl-L-cysteine (SAC), polyphenols, and \u03b3-aminobutyric acid (GABA), which collectively contribute to improved antioxidant capacity and gut health. This comprehensive review examines the microbial ecology underlying garlic fermentation, the biochemical pathways that generate bioactive metabolites, and the mechanistic basis by which fermented garlic employed in the broader food fortification strategy or incorporated into fortified therapeutic food formulations targeting clinical malnutrition, may support nutritional recovery in the context of Environmental Enteric Dysfunction (EED), the dominant gut pathology underlying stunting and wasting in low- and middle-income countries (LMICs). Fermented garlic is a bioactive-dense nutritional adjuvant rather than a macronutrient source, its clinical relevance lies in potential enhancement of gut barrier integrity, reduction of mucosal inflammation, and support of micronutrient bioavailability, rather than direct caloric contribution. Preclinical evidence from animal models demonstrates improvements in intestinal morphology, metabolic parameters, and immune function, suggesting potential utility in nutritionally stressed populations. However, well-designed human clinical trials specifically examining fermented garlic in malnourished populations are currently underrepresented in the literature, and all translational implications discussed herein remain preliminary. Substantial research gaps persist regarding optimal dosage, long-term clinical safety, and standardization of fermentation protocols. This review identifies critical research priorities necessary to establish fermented garlic as a scalable, culturally acceptable food-based complementary intervention for vulnerable populations worldwide.\n\nID: 42364134\nTitle: Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways.\nAbstract: Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID-19, and asthma. The normal lung is not sterile, with a distinct microbial ecosystem that is spatially varied along the respiratory tract. The biogeography of the lung microbiome is balanced between microbial microaspiration from the oral-pharynx and clearance. The mouth is an important reservoir for respiratory pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, and Staphylococcus aureus, as well as oral microbes (Porphyromonas, Prevotella, Fusobacterium, etc.). Poor oral hygiene and periodontitis increase the bacterial load that can be aspirated, and the host produces pro-inflammatory components that enhance microbial virulence and compromize epithelial integrity. Both poor oral hygiene and periodontitis have been associated with pneumonia, particularly in hospitals and nursing home settings. Periodontitis may also facilitate viral pneumonia (including COVID-19) by altering receptor expression and immune function. Periodontitis correlates with COPD severity and exacerbation frequency through pathways involving matrix metalloproteinases and cytokines. Periodontitis also is associated with asthma and acute exacerbations. Inflammation shapes the lung microbiome by impacting microbial nutrient availability through vascular leakage, inducing changes to epithelial cells which facilitate bacterial adherence, and inducing the production of cytokines, leading to mucus overproduction, inhibition of phagocytosis, and enhancement of microbial pathogen virulence. Multiple biological pathways have been examined in\u00a0vitro that suggest how \"the oral-lung axis\" influences pneumonia, COPD, and asthma. Periodontal treatment and effective oral hygiene should be well integrated into medical care to prevent and manage respiratory diseases.\n\nID: 42359789\nTitle: Mucin-derived sugars act as metabolic brakes controlling growth initiation in Akkermansia muciniphila.\nAbstract: Akkermansia muciniphila is a key member of the gut microbiota and plays important roles in host metabolism and health. In the colon, A. muciniphila extracts nutrients from oligosaccharide-rich mucin glycans that comprise the mucosa. However, this environment is complex and shaped by dietary inputs, microbiome metabolism, and mucin glycan composition varying across hosts, gastrointestinal regions, and physiological states. How strains of A. muciniphila integrate these nutrient signals into growth initiation and niche colonization remains unclear. Here, we compare physiological responses of a human- and mouse-derived strain of A. muciniphila, finding that dietary sugars differentially affect these isolates, suggesting host-associated tuning of metabolic capacity. In contrast, several mucin-derived sugars impose a conserved, concentration-dependent delay in growth initiation, implicating the lag phase as a critical metabolic checkpoint for growth. Genetic suppressor analysis identified sugar kinases and a component of the tricarboxylic acid cycle as genetically encoded control points linking glycan sugar exposure to the energy balance required for growth. These findings demonstrate that mucin-derived sugars function as both nutrients and metabolic stressors, regulating growth initiation. We propose that A. muciniphila employs metabolic \"brakes\" to coordinate growth with mucin composition, putatively linking host glycan landscapes to microbial physiology and ecological fitness within the mucus layer.\n\nID: 42356278\nTitle: Bioactive Low-Molecular-Weight Fraction from Limosilactobacillus fermentum CECT5716 Attenuates Intestinal Inflammation and Dysbiosis in DSS-Treated Mice.\nAbstract: Postbiotics, including cell-free supernatants and their fractions, have emerged as a safe and effective alternative to live probiotics for managing intestinal inflammation. This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis. By integrating epithelial protection, immunomodulation, and microbial reshaping, it represents a promising dietary strategy for the management of Inflammatory Bowel Diseases.\n\nID: 42345600\nTitle: Protective and Detoxifying Effects of Myrtus communis Essential Oil Against Bisphenol A-Induced Metabolic Disturbances in Wistar Rats.\nAbstract: Bisphenol A (BPA) is an endocrine disruptor widely used in industrial and consumer products. Its release into the environment raises major health concerns, particularly regarding metabolic disorders. After exposure, BPA leads to the accumulation of free BPA and its main metabolites, including bisphenol A-glucuronide (BPA-G), bisphenol A-disulfate (BPA-DS), and its chlorinated derivative, chlorinated bisphenol A-diglucuronide (BPA-DC). This study is aimed at evaluating the detoxifying effect of essential oil of Myrtus communis (EOMC) at 50, 100, and 200\u2009mg/kg, and vitamin E (100\u2009mg/kg), in male Wistar rats exposed to BPA (100\u2009mg/kg). Results showed a significant decrease in serum levels of BPA and its metabolites, along with increased urinary excretion, indicating enhanced biotransformation and elimination. BPA exposure also elevated fecal short-chain fatty acids (SCFAs) acetate, propionate, and butyrate, suggesting microbial dysbiosis and altered fermentation. EOMC and vitamin E treatments normalized SCFA profiles, demonstrating a modulatory effect on gut microbiota. The detection of \u03b1-pinene and 1,8-cineole in serum confirmed systemic bioavailability of EOMC and its role in detoxification. Overall, these findings highlight the protective effect of EOMC and vitamin E against BPA bioaccumulation and support their potential as natural detoxifying agents.\n\nID: 42337354\nTitle: Fermented food microbiome: influence on oral and gut microbiota, and human health.\nAbstract: The fermented food microbiome comprises live microorganisms, their genetic elements and their metabolites, and represents an established dietary approach for modulating host-microbiome interactions through the consumption of fermented foods. Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease.\n\nID: 42324603\nTitle: Cross-kingdom microbiome interactions along the gut-lung axis: immune-microecological coordination, shared mechanisms, and disease-context dependence in respiratory disorders.\nAbstract: Cross-kingdom dysbiosis of the gut microbiome along the gut-lung axis has emerged as a key driver of chronic and acute respiratory diseases. Beyond bacteria, the intestinal mycobiome and virome, including bacteriophages, shape mucosal immunity and metabolism through partially overlapping but non-redundant pathways. In this Review, we synthesize rapidly expanding evidence that fungi, bacteria, and phages in the gut form an integrated network that may influence susceptibility, inflammatory tone, and therapeutic responsiveness across asthma, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and lung cancer via the gut-lung axis. We first summarize how cross-kingdom communities in the intestine are organized and interact, highlighting a tripartite framework centered on pathogen-associated molecular pattern-pattern recognition receptor (PAMP-PRR) circuits, the short-chain fatty acid (SCFA)-regulatory T-cell axis, and tryptophan-indole-aryl hydrocarbon receptor (AHR) signaling. We then compare how these shared axes are differentially perturbed across asthma, COPD, ARDS, and lung cancer, using these disorders as representative but non-sequential disease contexts along a conceptual gradient of immune-microecological disruption. Finally, we discuss how dietary modulation, pre-/pro-/postbiotics, mycobiome- and virome-targeted strategies, and phage-based approaches could be rationally combined to restore gut-derived immunometabolic circuits and improve respiratory outcomes. By integrating cross-kingdom ecology with mucosal immunology, this Review provides an integrative interpretive framework suggesting that gut microbiome-targeted strategies may help refine prevention, stratification, and adjunctive treatment approaches in selected respiratory disease contexts.\n\nID: 42324006\nTitle: Effects of colloidal delivery systems for curcumin-Brassica rapa L. polysaccharide mixture encapsulation on physicochemical properties, stability, and gut microbiota modulation.\nAbstract: The therapeutic potential of curcumin is severely constrained by its poor physicochemical stability and low oral bioavailability. Co-formulation with Brassica rapa L. polysaccharide offers a promising strategy to enhance its functionality; however, the impact of different colloidal delivery systems on the encapsulation performance and subsequent biological fate of this mixture remains unclear. In this study, we systematically compared three spray-dried delivery platforms, including liposomes (LP-CP), sodium caseinate nanoparticles (SC-CP), and \u03b2-cyclodextrin inclusion complexes (CYC-CP), for encapsulating CP. Our results demonstrated that the carrier system critically determined encapsulation performance, with SC-CP exhibiting superior curcumin loading capacity (7.24%), curcumin thermal stability (82.87% retention at 95\u00a0\u00b0C), and favorable hygroscopicity profiles. Notably, SC-CP facilitated enhanced colonic accumulation in vivo, achieving a peak accumulation of 53.45% at 8\u00a0h post-gavage, representing a 15-fold increase compared to curcumin from unencapsulated CP. By integrating in vitro fermentation models with in vivo animal experiments and employing 16S rRNA sequencing alongside short-chain fatty acid (SCFA) analysis, we systematically elucidated the carrier-specific modulatory effects on the gut microbiota. In the in vitro fermentation system, SC-CP significantly promoted the production of acetate, propionate, and butyrate, while enriching butyrate-producing genera such as Lachnospiraceae_NK4A136_group. In the in vivo animal model, SC-CP intervention resulted in a 1.6-fold increase in cecal butyrate levels and a marked increase in the abundance of beneficial genera, including Akkermansia, demonstrating superior modulation of microbial community structure and metabolic function. Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology. This study provides a theoretical foundation for the rational selection of delivery systems to maximize the functional efficacy of bioactive ingredients in functional food applications.\n\nID: 42317760\nTitle: Global research status and development trends of chronic obstructive pulmonary disease and gut microbiota: a comprehensive analysis based on bibliometrics and knowledge visualization.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by airflow obstruction due to chronic bronchitis and/or emphysema, which can further progress to cor pulmonale and respiratory failure. In recent years, the association between gut microbiota and COPD has attracted extensive attention from researchers. This study aimed to explore the current research hotspots, knowledge gaps, and future research trends in the field of gut microbiota and COPD. A comprehensive search of literature related to gut microbiota and COPD published between 2009 and 2025 was conducted using the Web of Science and Scopus databases. Bibliometric analyses were performed using VOSviewer, CiteSpace, and R software. The number of publications in this field showed a significant growth trend from 2009 to 2025, with the highest number of publications recorded in 2024. China and the United States were the leading contributing countries, and institutions such as the University of Technology Sydney made important contributions. The International Journal of Chronic Obstructive Pulmonary Disease served as the core publication platform in this field, and Hansbro, Philip M. was a key contributor. Research in this field involved keywords including gut-lung axis, inflammation, probiotics, bacteria, and short chain fatty acid, which revealed the core themes and trends of studies on gut microbiota and COPD. To our knowledge, this study presents the first quantitative bibliometric analysis of the field of gut microbiota and COPD. The core research hotspots identified include the characteristics of gut microbiota alterations in COPD patients, as well as the reciprocal interactions and underlying mechanisms between COPD and gut microbiota; microbiota intervention strategies have also emerged as an emerging research direction. Investigating immune regulation mediated by gut microbial metabolites has become an important trend in this field. This study provides a comprehensive analysis of the current research status and key hotspots in the field of gut microbiota and COPD, offering important references and insights for subsequent studies in related fields.\n\nID: 42316508\nTitle: Macromolecular Organization in Lentinula edodes: Integrating Co-Occurring Bioactives for Structure-Function Relationships Across Gut Microbiota and Host Metabolism.\nAbstract: Diet-microbe-host interactions are increasingly recognized as properties of complex food matrices rather than the sum of isolated compounds. Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems.\n\nID: 42316485\nTitle: Bioactive carbohydrates: a mini-review.\nAbstract: Bioactive carbohydrates, including dietary fibers, prebiotics and resistant starches, play emerging roles in gut health, metabolic regulation, as well as chronic disease prevention. This mini review systematically classifies these compounds, summarizes their mechanisms of action, and evaluates their current and potential applications in functional food development. It also identifies several critical gaps, for example: how structural properties (type, source, molecular characteristics) and non-short-chain fatty acid fermentation metabolites influence physiological outcomes, the challenge of maintaining stability and functionality during processing (heat and pH optimization), the need to investigate nano-carbohydrate systems and prebiotic delivery matrices for microbiota modulation, metabolite release, and bioavailability, and the optimization of resistant starch extraction and application to balance functional benefits with sensory quality and in vivo validation. Translational evidence gaps, regulatory frameworks, personalized nutrition, and microbiome-based therapeutics are also discussed as future priorities. Generally, this mini-review provides a brief overview of the role of bioactive carbohydrates in food and nutrition. \u00a9 2026 Society of Chemical Industry.\n\nID: 42312862\nTitle: A phase-variable capsule facilitates Akkermansia muciniphila colonization of the intestinal mucus layer.\nAbstract: Akkermansia muciniphila is a mucophilic commensal bacterium that significantly impacts metabolic and immune homeostasis. However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment.\n\nID: 42297164\nTitle: Seaweed polysaccharides as multifunctional biotherapeutics in modulating gut microbiome, metabolic disorders and beyond: A review.\nAbstract: Seaweed-derived polysaccharides-fucoidan, laminarin, alginates, ulvan, and carrageenan-are often described as promising prebiotics with potential to influence the gut-liver-brain axis. Resistant to upper gastrointestinal digestion, they reach the colon where gut microbiota ferment them into metabolites, chiefly short-chain fatty acids (SCFAs). These metabolites in turn modulate intestinal barrier integrity, immune and metabolic homeostasis, and inter-organ signaling. However, a critical caveat is that each polysaccharide type exhibits substantial structural variability in molecular weight, degree and position of sulfation, monosaccharide composition, and linkage pattern, depending on species, harvest time, and extraction method. This variability fundamentally alters fermentation kinetics and SCFA profiles, yet most studies treat these polysaccharides as uniform entities. This review critically synthesizes current in vitro and in vivo evidence and emphasizes that the therapeutic significance of seaweed polysaccharides lies in their microbiota-mediated, multi-organ actions rather than in isolated biological effects. In addition, we analyzed the main challenges for food and health applications, including variability in polysaccharide sources and extraction methods, limited bioavailability, pollution risk, and the lack of coordinated global regulations. Addressing these gaps is essential for translating promising biological activities into safe, standardized functional components and for developing these polysaccharides into functional ingredients that can modulate the gut-liver-brain axis.\n\nID: 42293527\nTitle: Function of molecular-weight-optimized Astragalus polysaccharides in cisplatin-caused acute kidney injury: mechanisms centered on gut microbiota regulation and precise treatment approaches.\nAbstract: Cisplatin is a widely used chemotherapeutic drug for solid tumors, including colorectal cancer, but its clinical application is limited by dose-dependent nephrotoxicity, often resulting in acute kidney injury (AKI). The gut-kidney axis has emerged as a key factor in cisplatin-induced AKI, with gut microbial imbalance contributing to inflammation and metabolic dysregulation. Astragalus polysaccharides (APS), the main bioactive constituents of Astragalus membranaceus, have shown potential in mitigating AKI, partly through modulation of the gut microbiota. Clinical sequencing data indicate that cisplatin treatment reduces short-chain fatty acid (SCFA)-producing bacteria (e.g., Faecalibacterium, Roseburia) and increases potentially pathogenic groups (e.g., Enterobacteriaceae), leading to alterations in SCFA, amino acid, and bile acid metabolism. This study integrates these findings with existing literature to propose a molecular-weight (Mw)-defined APS model targeting the gut-kidney axis. While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects. Advanced gut-targeted delivery systems are also discussed as strategies to enhance APS bioavailability and colonic targeting. Understanding these Mw-dependent mechanisms is critical for developing APS as a precise adjunct therapy to prevent cisplatin-induced AKI and improve patient outcomes.\n\nID: 42291325\nTitle: Profiling of human lung and gut microbiomes in different conditions of chronic obstructive pulmonary disease using ontology-based evidence synthesis and reasoning.\nAbstract: Chronic Obstructive Pulmonary Disease (COPD) remains one of the leading global causes of morbidity and mortality, with increasing evidence highlighting microbial dysbiosis as a key factor in disease progression and exacerbation. To resolve the inherent heterogeneity in COPD microbiome research, we developed a standardized pipeline termed as Ontology-based Evidence Synthesis and Reasoning (O-ESR), utilizing the Ontology of Host-Microbiome Interactions (OHMI) framework. Our analysis included over 30 studies and identified more than 100 significantly altered bacterial taxa in the human airway and gut microbiomes of human COPD patients across three clinical conditions: COPD versus healthy controls, exacerbation versus stable states, and severe versus moderate diseases. Profiling across taxonomic levels revealed a marked airway expansion of pathogenic genera, including Haemophilus, Moraxella, Pseudomonas, and Burkholderia. Species-level analysis confirmed the specific enrichment of Haemophilus influenzae and Pseudomonas aeruginosa, supporting their roles in airway inflammation and exacerbation susceptibility. In contrast, the gut microbiome of COPD patients exhibited a decrease of beneficial anaerobes involved in short-chain fatty acid (SCFA) production, including Bifidobacterium bifidum, Faecalibacterium prausnitzii, and members of Lachnospiraceae and Ruminococcaceae. Notably, ontology-based reasoning identified a shared depletion of commensal genera such as Prevotella and Veillonella across both anatomical sites and all three clinical conditions, indicating a systemic and progressive loss of microbial diversity. This integrated analysis reveals a COPD-associated microbial landscape characterized by airway Proteobacteria expansion and gut SCFA-producer depletion, suggesting coordinated epithelial dysfunction, immune dysregulation, and gut-lung axis involvement. These findings demonstrate the power of ontological reasoning in decoding complex host-microbiome interactions, providing a robust foundation for microbiome-informed stratification and targeted interventions in COPD management.\n\nID: 42346391\nTitle: Multi-Targeted Intervention of Eucommia ulmoides and Its Bioactive Constituents Against Metabolic Syndrome: From Molecular Mechanisms and Gut Microbiota Modulation to Clinical Translation.\nAbstract: Background/Objectives: Metabolic syndrome (MetS) is a pressing global health challenge comprising obesity, hyperglycemia, hypertension, and hyperlipidemia. Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.\n\nID: 42316904\nTitle: The Role of Fecal Microbiome Transplantation in Steroid Hyporesponsive Asthma.\nAbstract: Asthma is a chronic inflammatory airway disease characterized by airflow obstruction, airway hyperresponsiveness, and structural remodeling. Corticosteroids remain the mainstay of asthma therapy; however, a substantial proportion of patients with severe disease develop steroid hyporesponsiveness, limiting therapeutic efficacy and increasing disease burden. Emerging evidence implicates the gut microbiome as a key regulator of systemic immune responses, with growing relevance to asthma pathogenesis and treatment responsiveness. In this study, we investigated whether gut microbiota dysbiosis contributes to steroid hyporesponsive lung inflammation and whether fecal microbiota transplantation (FMT) can restore steroid responsiveness. Using a steroid-hyporesponsive asthma model, we demonstrate that the disease is associated with significant gut microbial dysregulation, characterized by reduced microbial diversity and depletion of immunoregulatory taxa. FMT partially restored gut microbial diversity, normalized community structure, and selectively replenished beneficial commensal bacteria, including Akkermansia muciniphila and Faecalibacterium prausnitzii, while suppressing pathogenic taxa. Importantly, restoration of gut microbial balance was associated with attenuation of lung inflammation and improved steroid responsiveness. These findings support a functional gut-lung axis in steroid hyporesponsive asthma and identify modulation of gut microbiota as a potential therapeutic strategy. Incorporating microbiota-directed interventions such as FMT may represent a novel adjunct approach for the management of refractory steroid-hyporesponsive asthma.\n\nID: 42237852\nTitle: Study on the Alleviating Effect of Tropical Psidium guajava Basal Postbiotics on Hyperuricemia.\nAbstract: Hyperuricemia (HUA) is a growing global health concern with a younger onset trend. Using a high-purine diet-induced HUA mouse model, this study evaluated kidney, colon, and gut microbiota damage and investigated the effects of Psidium guajava basal postbiotics (PGP). PGP reduced xanthine oxidase activity, modulated purine metabolism, and increased beneficial gut bacteria (Akkermansia muciniphila) and short-chain fatty acids (acetate, butyrate, propionate). This led to decreased blood urea nitrogen, creatinine, and renal malondialdehyde, along with reduced inflammatory factors (IL-8, LPS). Consequently, PGP alleviated HUA and mitigated HUA-induced kidney and colonic damage. This study highlights the therapeutic potential of tropical postbiotics against HUA, offering a theoretical basis for dietary supplements in chronic disease prevention.\n\nID: 42075073\nTitle: Fermentation Enhances Antioxidant, Antiplatelet, and Anti-Inflammatory Properties of Oat- and Soy-Derived Dairy Alternatives.\nAbstract: The increasing demand for plant-based dairy alternatives has stimulated interest in their potential health-promoting properties, particularly when combined with fermentation processes that may enhance the bio-efficacy and bioavailability of bioactive compounds. The present study investigated the impact of fermentation on the antioxidant, antiplatelet, and anti-inflammatory activities of oat- and soy-based dairy alternatives. Total lipids were extracted and fractionated into lipophilic and amphiphilic lipid fractions, which were subsequently evaluated for antioxidant capacity using 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP) assays, as well as for their inhibitory activity against platelet aggregation induced by platelet-activating factor (PAF) or by ADP. Fermentation significantly enhanced the biological activity of the tested products, with fermented samples exhibiting lower IC50 values and thus more potent anti-inflammatory and antiplatelet efficacy and improved antioxidant performance compared with the non-fermented plant-based dairy alternative products. The amphiphilic lipid fractions demonstrated the strongest bioactivity, suggesting that fermentation promotes structural modifications in polar lipids that contribute to enhanced functional properties. Overall, fermented soy products exhibited stronger antiplatelet (anti-ADP) and anti-inflammatory (anti-PAF) activities, with lower IC50 values (indicating higher inhibitory potency), whereas fermented oat products demonstrated particularly enhanced antioxidant capacity, especially in TAC fractions, as evidenced by higher FRAP values and carotenoid content (e.g., oat yogurt TAC: 19.14 \u00b1 9.97 mg CE/g extract). In DPPH assays, TAC fractions of both soy and oat showed comparable radical scavenging activity (TEAC \u2248 0.019 for soy yogurt TAC), while ABTS and FRAP assays highlighted matrix-dependent differences between lipid fractions. Fatty acid analysis further indicated favorable compositional changes associated with fermentation, including favorable alterations in the n-6/n-3 fatty acid ratio of the fatty acid content of the bioactive polar lipid species, while OMICs analysis indicated the specific molecular species of phospho-/glyco-based polar lipids present in these products. These findings suggest that fermentation can substantially improve the biofunctional profile of plant-based dairy alternatives and highlight fermented oat- and soy-based products as promising dietary sources of bioactive polar lipids with potential cardioprotective properties.\n\nID: 41851729\nTitle: Parabacteroides goldsteinii-derived outer membrane vesicles alleviate acute lung injury via modulation of bile acid metabolism.\nAbstract: Acute respiratory distress syndrome (ARDS) is a severe clinical syndrome with limited therapeutic options. Acute lung injury (ALI) is widely used as an experimental animal model that recapitulates the key pathological features of human ARDS. Parabacteroides goldsteinii, a newly identified Gram-negative probiotic, exhibits anti-inflammatory effects in certain disease models. Gram-negative bacteria release nanoscale structures called outer membrane vesicles (OMVs), which show varying composition across species. The role of P. goldsteinii-derived OMVs (Pg-OMVs) in ALI or ARDS remains to be elucidated. In this study, we investigated the therapeutic potential of Pg-OMVs in a bleomycin (BLM)-induced ALI mouse model and explored their effects on pulmonary inflammation and gut microbiota composition. Compared to mice receiving BLM alone, Pg-OMV-treated mice exhibited significantly reduced inflammatory cell infiltration and lower levels of pro-inflammatory cytokines. Notably, Pg-OMV treatment significantly altered the gut microbiota composition, characterized by an increased abundance of Akkermansia muciniphila and a decreased abundance of Clostridia_bacterium. Fecal microbiota transplantation (FMT) experiments confirmed that the protective effects of Pg-OMVs were mediated via gut-lung axis. Further analysis revealed elevated cholic acid (CA) levels in the peripheral blood and bronchoalveolar lavage fluid following Pg-OMV treatment. CA was shown to suppress BLM-induced macrophage pyroptosis in the lung. Pharmacological inhibition of CA reversed the protective effects of Pg-OMVs, further confirming its pivotal role. In summary, Pg-OMVs increased the abundance of Akkermansia muciniphila while decreasing the abundance of Clostridia_bacterium in the gut, elevated systemic CA levels, and suppressed macrophage pyroptosis via inhibition of the NF-\u03baB pathway, thereby attenuating pulmonary inflammation and ultimately alleviating ALI. These findings highlight a novel therapeutic strategy for the treatment of ALI or ARDS by targeting the gut-lung axis.\n\nID: 41836373\nTitle: Akkermansia muciniphila primes lung-resident antiviral immunity via the gut-lung axis during SARS-CoV-2 infection.\nAbstract: The gut microbiota plays a central role in shaping systemic immunity and modulating the gut-lung axis, which is crucial during respiratory infections such as COVID-19. SARS-CoV-2 infection is known to disrupt the gut microbiome, but the downstream functional impacts on microbial metabolism and host immune responses remain insufficiently understood. Using K18-hACE2 transgenic mice, researchers investigated the effects of SARS-CoV-2 variants (WA and Omicron) on the gut microbiome and host immunity. Microbial composition and functional profiles were assessed post-infection. To test the therapeutic potential of Akkermansia muciniphila (A. muciniphila), live bacteria were administered prophylactically, and various outcomes were evaluated, including weight loss, lung pathology, immune cell phenotypes, and cytokine production. In K18-hACE2 transgenic mice infected with SARS-CoV-2, there was a marked reduction in gut microbial diversity, accompanied by a consistent enrichment of A. muciniphila. This microbial shift was associated with functional disruptions in key metabolic pathways, particularly those involved in glycosaminoglycan degradation and lipid metabolism, suggesting a broader impact of infection on microbial functionality. Remarkably, prophylactic administration of live A. muciniphila prior to infection led to significant protective effects. Treated mice exhibited reduced weight loss and improved lung histopathology compared to untreated controls. Local antiviral immune responses in the lung were notably enhanced without triggering excessive systemic inflammation. Mice receiving A. muciniphila also demonstrated elevated production of Th2 and Th17 cytokines, robust expansion of tissue-resident memory T cells, and the formation of inducible bronchus-associated lymphoid tissue (iBALT)-all indicative of potentiated mucosal immunity. These findings highlight a functional role for A. muciniphila not only as a microbial signature of COVID-19-associated dysbiosis but also as an active modulator of host immune responses during respiratory viral infections. These findings position A. muciniphila as both a biomarker of COVID-19-related gut dysbiosis and a potent live biotherapeutic candidate for respiratory infections. Its ability to enhance mucosal immune responses through gut-lung axis modulation highlights its promise in prophylactic strategies against viral respiratory diseases, including SARS-CoV-2.\n\nID: 41800246\nTitle: Gut-Lung Microbiota Axis Shapes the Immune Microenvironment and Immunotherapeutic Response in Lung Cancer.\nAbstract: The gut-lung axis microbiota plays a pivotal role in shaping the tumor immune microenvironment (TIME) and regulating immunotherapeutic responses in lung cancer. This review highlights that pulmonary and gut microbial dysbiosis drives lung cancer development through inducing chronic inflammation, remodeling the immune microenvironment, and reprogramming metabolism. Lung cancer patients exhibit distinct microbial signatures characterized by altered microbiotal diversity and enrichment of specific taxa like Streptococcus, Veillonella, and Bacteroidetes in the airways, along with gut microbial shifts involving decreased Firmicutes/Bacteroidetes ratio. These microbial alterations promote tumor progression via activation of pro-inflammatory pathways (e.g., interleukin-17 (IL-17)/interleukin-23 (IL-23) axis) and suppression of antitumor immunity.Notably, the gut-lung microbiome exerts a profound impact on immunotherapeutic efficacy: responders are enriched with beneficial microbes like Akkermansia muciniphila and Bifidobacterium that enhance CD8\u207a T cell responses, while non-responders show elevated levels of Gammaproteobacteria and Fusobacterium associated with immunosuppression. Regulatory mechanisms include systemic immune modulation by microbial metabolites such as short-chain fatty acids, as well as activation of key signaling pathways including cGAS-STING and CD40L-CD40/NF-\u03baB. Emerging translational applications encompass lung cancer diagnosis and immunotherapeutic response prediction via microbial biomarkers, as well as therapeutic interventions including fecal microbiota transplantation (FMT) and probiotic supplementation. Future studies should clarify microbe-host interaction mechanisms and develop personalized microbiota-based strategies to overcome immunotherapy resistance, offering the potential to revolutionize precision oncology through integrating microbiota modulation with conventional therapies.\n\nID: 41703840\nTitle: Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02 attenuate renal fibrosis and pathological autophagy in hyperuricemic nephropathy via gut-kidney axis.\nAbstract: Hyperuricemic nephropathy (HN) is a worldwide metabolic disorder marked by uric acid (UA) imbalance and renal tubulointerstitial fibrosis, yet therapies that both lower UA and prevent fibrosis remain limited. Targeting the gut-kidney axis with probiotics is a promising strategy, but most candidates are food-derived and not human-adapted. We isolated two Lactiplantibacillus strains, Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02, from the healthy newborn skin representing a relatively unperturbed, early-life human microbiome. In vitro, these two human-derived probiotic strains showed robust survival under simulated gastrointestinal conditions and efficiently degraded UA precursors (inosine, guanosine). In Uox-/- mice, oral supplementation with these probiotics for 12\u00a0weeks significantly reduced serum UA levels, improved renal function, and regulated key urate transporters, such as ABCG2, GLUT9, and OAT1, in kidney and ileum. The treatment also reinforced intestinal barrier integrity by upregulating tight junction proteins (Claudin-1, Occludin, ZO-1) and alleviated renal fibrosis by inhibiting the TGF-\u03b21/SMAD3 signaling pathway. Gut microbiome analysis showed that JWN01 and JWN02 administration reshaped the microbial composition by decreasing potentially harmful genera (Mammaliicoccus, Staphylococcus, Corynebacterium) and enriching beneficial taxa (Muribaculaceae, Lactiplantibacillus, Akkermansia). This microbial shift was accompanied by partial restoration of disturbed gut metabolites, including Coenzyme Q10 and p-cresol sulfate. Proteomic profiling of proximal tubules, along with subsequent validation, demonstrated that intervention with JWN01 and JWN02 suppressed pathological autophagy-evidenced by reduced ULK1, LC3A/B, and Beclin-1 expression, and increased P62 levels. Notably, the potential inflammation-related biomarkers MSP and IBA1, elevated in HN, were reversed following probiotic treatment. Together, these findings indicate that L. pentosus JWN01 and L. plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia.\n\nID: 41660421\nTitle: Unveiling the pathways of Xuanbai Chengqi Decoction in obese asthma: from immune modulation to microbial restoration.\nAbstract: Obesity asthma is a unique asthma phenotype, which has the characteristics of aggravation of clinical symptoms, change of immune response, and resistance to standard treatment. Obese asthma, as a clinical refractory asthma type, urgently needs effective and side-effect-free treatment. Xuanbai Chengqi Decoction (XBCQD) is a traditional Chinese medicine prescription widely used in the treatment of lung diseases, including asthma in China. However, the efficacy and mechanism of obese asthma remain to be explored. To elucidate the therapeutic effect of XBCQD on obese asthma and reveal its mechanism. Network pharmacology was used to predict the potential therapeutic targets and pathways of XBCQD in the treatment of obese asthma. We established a mouse model of obese asthma by feeding a high-fat diet combined with intraperitoneal injection of ovalbumin (OVA) to induce sensitization, and then intervened with intragastric administration of high, medium, and low doses of XBCQD. During the modeling period, lung function and body weight of mice were used to evaluate the preparation of the obese asthma model. H&E staining, RT-qPCR, ELISA, Western blot, and flow cytometry were used to quantify Th cell subsets, 16S rRNA sequencing was used to determine microbial composition, and GC/MS was used to detect the content of short-chain fatty acids in intestinal contents to explore the mechanism of Xuanbai Chengqi Decoction on obese asthma. Network pharmacology showed that XBCQD may improve obese asthma by affecting core targets such as IL-6, TNF, and Caspase1, and through signaling pathways such as the IL-17 signaling pathway, AGE-RAGE signaling pathway, TNF signaling pathway, and Th17 cell differentiation. Experimental studies have found that XBCQD can alleviate the symptoms of obese asthma and lung inflammation, reduce serum IgE, reduce the expression of IL-6, IL-17, and IL-23 in serum, to reduce lung inflammation induced by obese asthma in mice; flow cytometry of spleen tissue showed that XBCQD reduced the proportion of Th17 cells and restored the proportion of Treg cells. Proteomics showed that XBCQD inhibited the expression of NLRP3, Caspase-1, and IL-1\u03b2 by up-regulating the expression of GPR43, thereby inhibiting Th17-related protein ROR\u03b3t and restoring Treg-related protein Foxp3, thereby regulating immune imbalance. At the same time, XBCQD restored the intestinal microbial species, and restored the beneficial bacteria such as Dubosiella, Akkermansia_muciniphila, Rikenella, which were reduced in obese asthmatic mice, and increased the content of acetic acid, propionic acid, and butyric acid in intestinal flora metabolites. XBCQD regulates Th17/Treg immune imbalance in obese asthma by improving intestinal microecology and regulating SCFAs/GPR43/NLRP3 pathway. These findings provide new pharmacological evidence for its clinical application in obese asthma.\n\nID: 41564978\nTitle: Maxing Shigan decoction serves as a key component of Lianhua Qingwen in alleviating lung and gut injury by restoring gut microbiota homeostasis and inhibiting inflammation via TLR4/NF-\u03baB and JAK2/STAT3 dual regulation.\nAbstract: Lianhua Qingwen (LHQW), a clinically validated herbal medicine containing Maxing Shigan Decoction (MXSGT) and others, shows broad efficacy in various respiratory disease. However, its regulatory role on the gut-lung axis, particularly the contribution of its MXSGT components, remains unexplored. This study employed a formula-disassembled approach to decipher this mechanism. Three preparations, including the complete LHQW prescription, LHQW excluding MXSGT components (LHQW-MXSGT), and MXSGT along, were administered to LPS-induced acute lung injury and DSS-induced ulcerative colitis to evaluate their therapeutic effects via the gut-lung axis. Pathological changes, mucosal barrier integrity, inflammatory cell infiltration and pro-inflammatory cytokine levels were evaluated by H&E staining, histochemical staining, immunofluorescence, ELISA, RT-qPCR and Western blot. Metagenomic analysis (16S rDNA sequencing) was conducted to examine their regulatory role of gut microbiota. Network pharmacology analysis and cellular validation was employed to explore their underlying mechanisms. Our analyses demonstrated that LHQW and MXSGT, but not LHQW-MXSGT, significantly attenuated lung/intestinal pathology damage, reduced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), and restored gut barrier proteins (ZO-1, Occludin, MUC2). LHQW/MXSGT suppressed pathogenic bacteria (Escherichia coli, Salmonella, Klebsiella pneumoniae) while enriching Akkermansia muciniphila, correlating with decreased systemic LPS. Network pharmacology and subsequent validation identified dual inhibition of TLR4/NF-\u03baB and JAK2/STAT3 pathways as key mechanism of MXSGT. In conclusion, MXSGT serves a pivotal pharmacologically active component of LHQW for its gut-lung axis regulation, acting through gut microbiota homeostasis restoration, intestinal barrier integrity maintenance, and anti-inflammatory signaling pathways, providing compelling scientific evidence supporting LHQW's potential therapeutic application in managing diseases characterized by comorbid gut and lung inflammation.\n\nID: 41456349\nTitle: Heat-inactivated Akkermansia muciniphila AKK PROBIO attenuates hyperuricemia via integrated modulation of uric acid metabolism, TLR4/NF-\u03baB/NLRP3 pathway, and gut microbiota.\nAbstract: Hyperuricemia is a metabolic disorder associated with multiple comorbidities, yet effective therapies with minimal side effects remain limited. This study demonstrates that heat-inactivated Akkermansia muciniphila AKK PROBIO significantly reduces serum uric acid levels in hyperuricemic mice (24.1\u00a0%, P\u00a0<\u00a00.05). The therapeutic effects are mediated through multiple interconnected mechanisms, including improved renal function (reduced serum creatinine and blood urea nitrogen), suppression of hepatic xanthine oxidase activity, mitigation of oxidative stress (lower malondialdehyde and higher superoxide dismutase activity), and attenuation of inflammation via inhibition of the TLR4/IKK\u03b2/NF-\u03baB pathway and NLRP3 inflammasome activation. Notably, levels of pro-inflammatory cytokines (IL-1\u03b2, IL-2, TNF-\u03b1) were downregulated, whereas anti-inflammatory cytokine IL-10 was upregulated. Furthermore, the probioctic treatment enhanced uric acid excretion by modulating key transporters (ABCG2 and GLUT9). Gut microbiota analysis revealed a restored Bacteroidota/Bacillota ratio, increased abundance of Rikenellaceae, elevated short-chain fatty acids, and reduced branched-chain fatty acids. Collectively, these findings indicate that heat-inactivated A. muciniphila AKK PROBIO may represent a promising therapeutic strategy for hyperuricemia management.\n\nID: 41301995\nTitle: Dietary Supplementation with Yak Stomach Lysozyme Improves Intestinal Health and Nutrient Metabolism in Weaned Piglets Challenged with Enterotoxigenic Escherichia coli (ETEC).\nAbstract: Post-weaning diarrhea caused by Enterotoxigenic Escherichia coli (ETEC) is a major disease in piglets and leads to substantial economic losses in the swine industry. Compared to conventional lysozyme, yak stomach lysozyme (YSL) demonstrates distinctive resistance to pepsin, trypsin, high temperature, and acidic conditions. This study investigated the effects of dietary YSL supplementation on intestinal health in weaned piglets challenged with ETEC, utilizing metabolomics and proteomics. A total of 18 weaned piglets were randomly divided into three groups: control (C), diarrhea (D), and YSL treatment (YLT). Groups C and D were fed a basal diet, while the YLT group received the basal diet supplemented with YSL at a dosage of 100,000 U/kg following ETEC challenge. Following an acclimation period, piglets in groups D and YLT were orally challenged with ETEC, while group C received the same volume of sterile LB broth. The feeding trial lasted for 21 days before sample collection. The results demonstrated that dietary supplementation with YSL significantly reduced the diarrhea rate (p < 0.05). Compared with the D group, the YLT group exhibited significantly increased serum albumin levels (p < 0.05), along with a tendency toward greater villus height (p = 0.085) and higher serum glucose levels (p = 0.052), indicating an improvement in nutritional and metabolic status Metabolomic analysis identified 260 differentially abundant metabolites between the YLT and D groups (81 upregulated, 179 downregulated), which were predominantly enriched in pathways related to amino acid biosynthesis and metabolism, purine metabolism, and nucleic acid metabolism. Proteomic profiling revealed 571 differentially expressed proteins (237 upregulated, 334 downregulated). Upregulated proteins were mainly involved in arginine biosynthesis and base excision repair, while downregulated proteins were associated with the PPAR signaling pathway and Salmonella infection. In summary, dietary YSL supplementation alters the metabolic and proteomic profiles in the intestines of diarrheic piglets, potentially improving gut barrier function and nutrient utilization. This study offers novel insights into the potential of YSL as a promising feed additive for prevention of post-weaning diarrhea in pigs.\n\nID: 41030386\nTitle: In vitro fecal fermentation demonstrates the prebiotic-like properties of quinoa modulated by different preparation methods.\nAbstract: Quinoa grain represents an excellent source of nutrition, including protein, lipids, and fiber. Quinoa processing and cooking alters its chemical composition and bioavailability of nutrients, and while extracts have been studied, little is known about the impact of quinoa food products on the human gut microbiota. One selected quinoa line was tested in raw, boiled, extruded, and baked (cookie) forms for its ability to modulate fecal microbiota from 10 healthy donors. After in vitro digestion, samples underwent fecal fermentation with measurements taken at 0, 6, 12, 24, and 48\u00a0h (h). Boiled and extruded quinoa exhibited significantly higher total polyphenol content when compared to raw quinoa (p\u00a0<\u00a00.05), while baked quinoa had lower polyphenol content, though the difference was not significant. Fecal fermentation of pre-digested raw and processed quinoa significantly increased (p\u00a0<\u00a00.05) beneficial lactic acid-producing bacterial (LAB) genera, including Bifidobacterium and Lactobacillus. All quinoa samples (raw, boiled, extruded, and baked) significantly increased Bifidobacterium abundance from 6 to 48\u00a0h compared to the start of fermentation (0\u00a0h), while Lactobacillus increased significantly in boiled, baked, and extruded samples at 12-48\u00a0h. Pediococcus and Weissella were more abundant in raw quinoa, suggesting that less-processed plant material might be harder to ferment. These findings highlight quinoa's prebiotic properties, which are largely preserved across various cooking methods. Future studies on quinoa and other grain products should integrate food chemistry and gut microbiota outcomes to identify physicochemical properties that influence microbiota responses.\n\nID: 40882135\nTitle: Gut-kidney axis modulation by viable and inactivated Akkermansia muciniphila mitigates avian hyperuricemia through microbial-metabolic crosstalk.\nAbstract: Hyperuricemia (HUA) has become the fourth most important health-threatening risk factor after hypertension, hyperglycemia, and hyperlipidemia, but the efficacy of existing uric acid-lowering treatments (ULT) is poor, and there is an urgent need to explore novel ULT strategies. Akkermansia muciniphila (A. muciniphila), a next-generation probiotic, shows promise in promoting intestinal homeostasis and metabolic regulation. Previous studies have demonstrated the potential application of A. muciniphila in ULT, but its specific mechanism has not been elucidated. In this study, we isolated a strain of A. muciniphila, named K101, from the cecum of goslings. In vitro experiments showed that K101 directly degrades uric acid, suggesting a potential microbial-metabolic crosstalk mechanism for anti-HUA. In vivo experiments showed that K101 increased the abundance of uric acid metabolism-related microbiota, such as A. muciniphila and Lactobacillus. Functionally, K101 synergistically promoted uric acid excretion by activating the intestinal excretory protein ABCG2 and inhibiting the renal uric acid reabsorption protein GLUT9. In addition, K101 provides a stable environment for uric acid metabolism by inhibiting renal inflammatory responses. Overall, A. muciniphila K101 exerts anti-HUA effects by remodeling the intestinal microbiota and excretion of uric acid through the gut-renal axis. This study offers new insights into microbial-metabolic crosstalk in uric acid metabolism in A. muciniphila and identifies potential targets for gout prevention and ULT strategy development.IMPORTANCEThe rising prevalence of hyperuricemia (HUA) underscores the need for new therapies and treatment approaches. Our study highlights the developmental and therapeutic potential of natural uric acid-degrading bacteria discovered in the avian gut, expanding the range of bacteria with possible medical applications. Another key finding is the notable efficacy of microbiota metabolites in alleviating HUA. While the underlying mechanisms warrant further investigation, these findings offer promising insights into microbiota-based therapeutics.\n\nID: 40815946\nTitle: Puerarin-rich compound Puerariae lobatae formulas alleviate hyperuricemia in mice by enhancing renal and intestinal function through regulating gut microbiota.\nAbstract: Hyperuricemia, a metabolic disorder strongly associated with gout and cardiorenal diseases, has become a global health threat affecting over 15% of the worldwide population. Current pharmacotherapies face limitations due to adverse effects during prolonged use. Natural medicines like Radix Puerariae Lobatae have demonstrated therapeutic potential with superior safety profiles. This study investigated the anti-hyperuricemic efficacy of compound Puerariae lobatae formulas (PLF1 and PLF2) and their bioactive component puerarin, focusing on their mechanisms for enhancing renal/intestinal uric acid excretion, alleviating pathological damage, and modulating gut microbiota composition. A hyperuricemic mouse model was established using an adenine/potassium oxonate diet. Mice were treated with PLF1 (250/500 mg/kg), PLF2 (300/600 mg/kg), puerarin (100 mg/kg), or benzbromarone (40 mg/kg, positive control). Plasma and tissue uric acid levels, XOD and ADA activities, and renal/intestinal transporter expression (ABCG2, OAT1) were analyzed. Histopathological examinations were performed using HE staining to assess kidney, liver, and intestinal integrity. Gut microbiota composition was evaluated via PacBio Sequel II 16S rRNA sequencing. Antibiotic-induced microbiota depletion and fecal microbiota transplantation (FMT) approaches were employed to validate microbiota-dependent effects. PLF1, PLF2, and puerarin significantly reduced plasma uric acid levels and suppressed XOD/ADA activities. Histopathological analysis demonstrated marked improvements in renal tubular injury, hepatic steatosis, and intestinal structural integrity, including restoration of villus architecture and crypt morphology. The expression of renal ABCG2 and OAT1, as well as intestinal ABCG2, was significantly upregulated, accompanied by enhanced expression of colonic tight junction proteins (ZO-1 and occludin). Antibiotic-induced microbiota depletion abolished the hypouricemic effect of puerarin, while FMT from puerarin-treated donors significantly alleviated hyperuricemia in recipient mice. Gut microbiota analysis revealed that both PLF2 and puerarin selectively enriched the beneficial bacterium Akkermansia muciniphila while simultaneously reducing pathogenic taxa. This study establishes Puerariae lobatae formulas and puerarin as multi-target therapeutics for hyperuricemia, offering dual advantages over conventional drugs by enhancing renal/intestinal uric acid excretion while also repairing organ damage, and remodeling gut microbiota to enrich probiotics like A. muciniphila. The microbiota-dependent efficacy of puerarin not only underscores its potential as a novel natural therapeutic agent but also provides critical pharmacological evidence for advancing puerarin and Radix Puerariae Lobatae-based formulas in hyperuricemia treatment, bridging traditional herbal medicine with modern microbiota-targeting strategies.\n\nID: 40749263\nTitle: The industrial biocide benzisothiazolinone impairs pathogen resistance in larval zebrafish by inducing microbiota dysbiosis.\nAbstract: Benzisothiazolinone (BIT), a most widely-used isothiazolinone biocide, has been detected in water environments, posing risks to aquatic ecosystems. However, toxicological studies of BIT in aquatic organisms are still limited. This study exposed zebrafish embryos to 0, 1, 10, 100, and 1000 \u03bcg/L BIT for 14 days, and investigated the effect of BIT on the innate immune function of larval fish. 16S rRNA sequencing revealed that BIT exposure reduced microbial diversity and richness, while increased pathogenic genera like Plesiomonas and Acinetobacter in larval fish. Then, the intestinal structure and gut barrier function were impaired, and the elevated lipopolysaccharides levels activated the Toll-like receptor signaling pathway and triggered a pro-inflammatory innate immune response in zebrafish. The ability of zebrafish to resist pathogen infection was further impaired, as indicated by a failed recruitment of macrophages in the intestinal area after Escherichia coli infection. Whereas, dietary administration of probiotic Lactobacillus rhamnosus ameliorated the immunotoxicity of BIT, and restored the zebrafish larvae' immunity against pathogens. These findings elucidated the adverse effect of BIT on the innate immune function of larval zebrafish from the perspective of intestinal health and microbial disruption, and also provided insights into probiotic-based strategies for mitigating isothiazolinone biocides toxicity in aquatic organisms.\n\nID: 40616741\nTitle: Gout, Hyperuricemia, and the Intestinal Microbiome.\nAbstract: Gout is a disease of hyperuricemia (HU) leading to monosodium urate crystal deposition in the joint, resulting in inflammation and joint damage. Recently, efforts have been made to characterize the intestinal microbiome of patients who suffer from HU and gout, and pre-clinical studies have evaluated the utility of prebiotics and probiotics in alleviating gout. Herein we review recent notable studies addressing these topics. In brief, the \"gouty\" microbiome is characterized by reduced diversity, an elevated Bacteroides: Firmicutes ratio, and reduced presence of Akkermansia and Bifidobacterium. In anserine models, supplementation with Lactobacillus probiotic strains appears to reduce serum urate (SU) and HU-induced inflammation. Murine models suggest that the chicory-derived prebiotic inulin may reduce SU, and oral supplementation with the anti-inflammatory short-chain fatty acid butyrate may lower SU by enhancing urate excretion and alleviate HU-induced tissue inflammation. Many of these studies are limited by modest numbers of participants and/or incompletely documented experimental controls, and, in the case of animal models, questionable reproducibility in humans. Many studies have been geographically limited. There remains a need for more information regarding the features of the \"gouty\" microbiome in wider populations, as well as for additional well-controlled probiotic and prebiotic studies in more physiologically relevant animal models prior to clinical trials.\n\nID: 40431419\nTitle: Coix Seed Oil Alleviates Hyperuricemia in Mice by Ameliorating Oxidative Stress and Intestinal Microbial Composition.\nAbstract: Background: Coix seed oil (YRO), rich in unsaturated fatty acids, has emerged as a promising intervention for hyperuricemia (HUA) due to its potential to alleviate oxidative damage and support organ health. Methods: The fatty acid composition of YRO was determined by gas chromatography-mass spectrometry (GC-MS). A HUA mouse model was established, and serum markers and hepatic enzymes were evaluated. Renal mitochondrial function was assessed using immunohistochemistry and immunofluorescence, and urate transporter expression, along with key signaling proteins, was quantified by Western blot analysis. Additionally, gut microbiota composition was analyzed, and non-targeted metabolomics was performed to observe alterations in serum lipid metabolites. Results: YRO significantly reduced serum uric acid (UA) levels and normalized hepatic enzyme activities. Histological evaluation revealed less tissue damage in both the kidney and the intestine. In the kidney, YRO improved mitochondrial function and supported antioxidant defenses via regulation of Keap1/Nrf2 signaling. In the intestine, YRO enhanced barrier integrity by increasing ZO-1, Occludin, and Claudin-1 expression. Moreover, YRO modulated gut microbiota by increasing beneficial bacteria (Muribaculaceae, Prevotellaceae UCG-001, Lachnospiraceae_ NK4A136_group, Akkermansia) while suppressing harmful species (Bacteroides, Dubosiella). Lipid metabolomics indicated a restoration of phospholipid balance through modulation of the PI3K/AKT/mTOR pathway. Conclusions: YRO supported metabolic health by promoting UA homeostasis, enhancing mitochondrial function, reinforcing antioxidant capacity, and maintaining gut integrity. These findings suggest that coix seed oil could serve as a nutritional supplement in managing HUA and related metabolic disturbances.\n\nID: 40136712\nTitle: Impact of a High-Fat Diet on the Gut Microbiome: A Comprehensive Study of Microbial and Metabolite Shifts During Obesity.\nAbstract: Over the last few decades, the prevalence of metabolic diseases such as obesity, diabetes, non-alcoholic fatty liver disease, hypertension, and hyperuricemia has surged, primarily due to high-fat diet (HFD). The pathologies of these metabolic diseases show disease-specific alterations in the composition and function of their gut microbiome. How HFD alters the microbiome and its metabolite to mediate adipose tissue (AT) inflammation and obesity is not well known. Thus, this study aimed to identify the changes in the gut microbiome and metabolomic signatures induced by an HFD to alter obesity. To explore the changes in the gut microbiota and metabolites, 16S rRNA gene amplicon sequencing and metabolomic analyses were performed after HFD and normal diet (ND) feeding. We noticed that, at taxonomic levels, the number of operational taxonomic units (OTUs), along with the Chao and Shannon indexes, significantly shifted in HFD-fed mice compared to those fed a ND. Similarly, at the phylum level, an increase in Firmicutes and a decrease in Bacteroidetes were noticed in HFD-fed mice. At the genus level, an increase in Lactobacillus and Ruminococcus was observed, while Allobaculum, Clostridium, and Akkermansia were markedly reduced in the HFD group. Many bacteria from the Ruminococcus genus impair bile acid metabolism and restrict weight loss. Firmicutes are efficient in breaking down complex carbohydrates into short-chain fatty acids (SCFAs) and other metabolites, whereas Bacteroidetes are involved in a more balanced or efficient energy extraction. Thus, an increase in Firmicutes over Bacteroidetes enhances the absorption of more calories from food, which may contribute to obesity. Taken together, the altered gut microbiota and metabolites trigger AT inflammation, which contributes to metabolic dysregulation and disease progression. Thus, this study highlights the potential of the gut microbiome in the development of therapeutic strategies for obesity and related metabolic disorders.\n\nID: 40029218\nTitle: Investigating the modulatory effects of Pu-erh tea on the gut microbiota in ameliorating hyperuricemia induced by circadian rhythm disruption.\nAbstract: Circadian rhythm disruption (CRD) can induce a variety of metabolic disorders. Our previous laboratory studies have shown that Pu-erh tea could alleviate CRD-induced syndromes, including obesity, intestinal dysfunction, and tryptophan metabolism disorders. However, its potential protective mechanism against CRD-induced hyperuricaemia remains unclear. In this work, we found that polyphenols of Pu-erh tea were significantly released in the stage of intestinal digestion, which might promote their interaction with gut microbes. Through animal experiments, C57BL6/J mice were given water or different doses of Pu-erh tea for 60 days, followed by a 90-day CRD, the lifestyle of modern individuals who frequently stay up late. Our results indicated that CRD mice exhibited high serum uric acid levels and gut microbiota disorders. Pu-erh tea intake significantly reshaped the gut microbiome, especially increasing the abundance of Bifidobacterium, Akkermansia and Faecalibaculum, and increased the production of short-chain fatty acids (SCFAs), especially acetic acid, which restored the function of the intestinal barrier. This improvement further regulated oxidative stress pathways (NRF2/HO-1), reduced systemic inflammatory response (IL-6, IL-1\u03b2, and TNF-\u03b1), restored hepatic function (SOD, MOD, CAT, and GSH) and modulated the activity of enzymes related to UA metabolism in the liver (XOD and ADA). Finally, Pu-erh tea intake promoted the excretion of UA and reduced the levels of UA and xanthine in the serum. Moreover, the results of antibiotic experiments showed that the UA improvement effect of Pu-erh tea depended on the existence of the gut microbiota. Collectively, Pu-erh tea intake has the potential to prevent CRD-induced hyperuricaemia by reshaping the gut microbiota.\n\nID: 39925238\nTitle: Dietary Oligosaccharides Isolated from Coix Seed Mitigate Hyperuricemia through Modulation of Lipid Metabolites and Intestinal Homeostasis.\nAbstract: Hyperuricemia (HUA) is a prevalent metabolic disorder associated with chronic disease, posing significant global health challenges. Coix seed, a traditional cereal, has shown therapeutic potential against HUA, with oligosaccharides serving as its primary active components. However, the mechanisms of Coix seed oligosaccharides in HUA management remain underexplored. In this study, a novel oligosaccharide was isolated from Coix seed (CSO) through enzymatic hydrolysis and column chromatography. Structural analysis revealed that the CSO is primarily composed of glucose, with a backbone of \u21924)-\u03b2-Glcp-(1\u2192 linkages. CSO exhibited significant hypouricemic effects in both adenosine-induced HK-2 cells and HUA mice by inhibiting XOD activity and regulating urate transporter expression. Furthermore, CSO restored lipid imbalances, particularly in PS and PC, and modulated gut microbiota by increasing Ruminococcus, Akkermansia, and Lachnospiraceae abundance to alleviate HUA-related systemic disturbances. Importantly, CSO alleviated HUA-induced renal injury by downregulating the IL-6/JAK2/STAT3 signaling pathway. This study provided meaningful evidence supporting the effect of CSO on HUA and offered new directions for natural oligosaccharide interventions in metabolic health.\n\nID: 39649550\nTitle: Gut microbiota participates and remodels host metabolism: From treating patients to treating their gut flora.\nAbstract: In this editorial, we comment on Liu et al's article published in the recent issue of the World Journal of Gastroenterology. Biochemically and pathologically, Liu et al proved that the urate-lowering activity of leech total protein (LTP) was mainly attributed to the rectification of gut microbiota. Specifically, we noticed the change in Bacteroides and Akkermansia after LTP administration. Both bacteria have been reported to alleviate metabolic dysfunction-associated steatohepatitis and other chronic metabolic diseases. LTP was administrated through intragastric manners. Most possibly, LTP would be digested by the gut microbiota further. The anti-hyperuricemia effects should, to the most possible extent, be exerted by the peptides or their secondary metabolic products. Human gut microbiota communicates with other organs through metabolites generated by the microbes or co-metabolized with the host. Whether the anti-hyperuricemia effect could be partially ascribed to the microbiota metabolites also deserves to be discussed. Although metabolomics analysis was performed for serum samples, fecal metabolomics was highly advocated which could facilitate exact mechanism explanation. This study implied that gut microbiota contains many unexplored targets with different therapeutic potentials. It is foreseeable that utilizing these targets can avoid the impairment or side effects of directly using human targets to some extent.\n\nID: 39189204\nTitle: Beneficial Bacteria in the Gut Microbiota May Lead to Improved Metabolic and Immunological Status in Chronic Obstructive Pulmonary Disease.\nAbstract: The progression of chronic obstructive pulmonary disease (COPD) is characterized by functional changes in the airways. The lung-gut axis and gut microbiota (GM) have been linked to the pathophysiology of airway diseases. Regarding COPD, studies have shown that GM alterations could be related the stages of this disease. However, the relationship between GM and clinical, biochemical and immunological parameters in patients with COPD are not well understood. The aim of this study was to compare the relative abundance of specific groups of beneficial gut bacteria between COPD patients and healthy controls (CTLs) in order to evaluate relationships with metabolic and inflammatory markers in COPD. We included 16 stable COPD patients and 16 healthy volunteer CTLs. The relative abundances of Bifidobacterium spp. (Bf) and Akkermansia muciniphila (Akk) bacteria and the Bacteroidetes and Firmicutes phyla were assessed by qPCR. Pulmonary function was evaluated by spirometry, biochemical parameters by colorimetric methods and plasma cytokine levels by cytometric bead array analysis. The Firmicutes/Bacteroides ratio was related to emergency hospital visits and six-minute walk test (6MWT) results. Furthermore, the relative abundance of Bf was associated with plasma concentrations of glucose, triglycerides, HDL-C and IL-10. In addition, Firmicutes levels and the Firmicutes/Bacteroidetes ratio were associated with the IL-12/IL-10 ratio, while Akk abundance was linked to IL-12 levels. The present findings suggest that the abundance of beneficial bacteria in the GM could influence clinical presentation and immunoregulation in COPD.\n\nID: 39156502\nTitle: Leech Poecilobdella manillensis protein extract ameliorated hyperuricemia by restoring gut microbiota dysregulation and affecting serum metabolites.\nAbstract: Hyperuricemia (HUA) is a public health concern that needs to be solved urgently. The lyophilized powder of Poecilobdella manillensis has been shown to significantly alleviate HUA; however, its underlying metabolic regulation remains unclear. To explore the underlying mechanisms of Poecilobdella manillensis in HUA based on modulation of the gut microbiota and host metabolism. A mouse model of rapid HUA was established using a high-purine diet and potassium oxonate injections. The mice received oral drugs or saline. Additionally, 16S rRNA sequencing and ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry-based untargeted metabolomics were performed to identify changes in the microbiome and host metabolome, respectively. The levels of uric acid transporters and epithelial tight junction proteins in the renal and intestinal tissues were analyzed using an enzyme-linked immunosorbent assay. The protein extract of Poecilobdella manillensis lyophilized powder (49 mg/kg) showed an enhanced anti-trioxypurine ability than that of allopurinol (5 mg/kg) (P < 0.05). A total of nine bacterial genera were identified to be closely related to the anti-trioxypurine activity of Poecilobdella manillensis powder, which included the genera of Prevotella, Delftia, Dialister, Akkermansia, Lactococcus, Escherichia_Shigella, Enterococcus, and Bacteroides. Furthermore, 22 metabolites in the serum were found to be closely related to the anti-trioxypurine activity of Poecilobdella manillensis powder, which correlated to the Kyoto Encyclopedia of Genes and Genomes pathways of cysteine and methionine metabolism, sphingolipid metabolism, galactose metabolism, and phenylalanine, tyrosine, and tryptophan biosynthesis. Correlation analysis found that changes in the gut microbiota were significantly related to these metabolites. The proteins in Poecilobdella manillensis powder were effective for HUA. Mechanistically, they are associated with improvements in gut microbiota dysbiosis and the regulation of sphingolipid and galactose metabolism.\n\nID: 39132829\nTitle: Alterations in the gut microbiome and metabolism profiles reveal the possible molecular mechanism of renal injury induced by hyperuricemia in a mouse model of renal insufficiency.\nAbstract: Objectives: To investigate the role of the intestinal flora and metabolites in the development of hyperuricemic renal injury in chronic kidney disease (CKD).Methods: Unilaterally nephrectomized mice were fed with adenine and potassium oxonate for 9 weeks. HE staining combined with plasma biochemical indicators was used to evaluate renal pathological and functional changes. We conducted 16S rRNA sequencing and untargeted metabolomics on feces and plasma samples to reveale changes in intestinal microbiota and metabolites.Result: Our analysis revealed significant differences in 15 bacterial genera, with 7 being upregulated and 8 being downregulated. Furthermore, metabolomic analysis revealed changes in the distribution of amino acid and biotin metabolites in basic metabolic pathways in both feces and serum. Specifically, differentially abundant metabolites in feces were associated primarily with histidine metabolism; the biosynthesis of phenylalanine, tyrosine, and tryptophan; and tyrosine metabolism. In plasma, the differentially abundant metabolites were involved in multiple metabolic pathways, including aminoacyl-tRNA biosynthesis; glycine, serine, and threonine amino acid metabolism; valine, leucine, and isoleucine biosynthesis; tyrosine biosynthesis and metabolism; biotin metabolism; and taurine and hypotaurine metabolism. Furthermore, correlation analysis revealed that Akkermansia, UCG-005, Lachnospiraceae_NK4A136_group, Lactococcus, and Butymonas were associated with various differentially abundant metabolites as well as renal function, oxidative stress, and mitophagy. The changes in the intestinal flora observed in hyperuricemia may lead to imbalances in amino acid and biotin metabolism in both the intestine and host, ultimately affecting oxidative stress and mitophagy in mice and accelerating the progression of CKD.Conclusion: Our findings provide insights into a potential pathogenic mechanism by which hyperuricemia exacerbates renal injury in mice with renal insufficiency. Understanding these pathways may offer new therapeutic strategies for managing hyperuricemic renal injury in CKD patients.\n\nID: 39030804\nTitle: The role of fermentation with lactic acid bacteria in quality and health effects of plant-based dairy analogues.\nAbstract: The modern food industry is undergoing a rapid change with the trend of production of plant-based food products that are more sustainable and have less impact on nature. Plant-based dairy analogues have been increasingly popular due to their suitability for individuals with milk protein allergy or lactose intolerance and those preferring a plant-based diet. Nevertheless, plant-based products still have insufficient nutritional quality, undesirable structure, and earthy, green, and bean-like flavor compared to dairy products. In addition, most plant-based foods contain lesser amounts of essential nutrients, antinutrients limiting the bioavailability of some nutrients, and allergenic proteins. Novel processing technologies can be applied to have a homogeneous and stable structure. On the other hand, fermentation of plant-based matrix with lactic acid bacteria can provide a solution to most of these problems. Additional nutrients can be produced and antinutrients can be degraded by bacterial metabolism, thereby increasing nutritional value. Allergenic proteins can be hydrolyzed reducing their immunoreactivity. In addition, fermentation has been found to reduce undesired flavors and to enhance various bioactivities of plant foods. However, the main challenge in the production of fermented plant-based dairy analogues is to mimic familiar dairy-like flavors by producing the major flavor compounds other than organic acids, yielding a flavor profile similar to those of fermented dairy products. Further studies are required for the improvement of the flavor of fermented plant-based dairy analogues through the selection of special microbial cultures and formulations.\n\nID: 38865030\nTitle: A Lactobacillus Combination Ameliorates Lung Inflammation in an Elastase/LPS-induced Mouse Model of Chronic Obstructive Pulmonary Disease.\nAbstract: Chronic obstructive pulmonary disease (COPD) is the world's leading lung disease and lacks effective and specific clinical strategies. Probiotics are increasingly used to support the improvement of the course of inflammatory diseases. In this study, we evaluated the potential of a lactic acid bacteria (LAB) combination containing Limosilactobacillus reuteri GMNL-89 and Lacticaseibacillus paracasei GMNL-133 to decrease lung inflammation and emphysema in a COPD mouse model. This model was induced by intranasal stimulation with elastase and LPS for 4\u00a0weeks, followed by 2\u00a0weeks of oral LAB administration. The results showed that the LAB combination decreased lung emphysema and reduced inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in the lung tissue of COPD mice. Microbiome analysis revealed that Bifidobacterium and Akkermansia muciniphila, reduced in the gut of COPD mice, could be restored after LAB treatment. Microbial \u03b1-diversity in the lungs decreased in COPD mice but was reversed after LAB administration, which also increased the relative abundance of Candidatus arthromitus in the gut and decreased Burkholderia in the lungs. Furthermore, LAB-treated COPD mice exhibited increased levels of short-chain fatty acids, specifically acetic acid and propionic acid, in the cecum. Additionally, pulmonary emphysema and inflammation negatively correlated with C. arthromitus and Adlercreutzia levels. In conclusion, the combination of L. reuteri GMNL-89 and L. paracasei GMNL-133 demonstrates beneficial effects on pulmonary emphysema and inflammation in experimental COPD mice, correlating with changes in gut and lung microbiota, and providing a potential strategy for future adjuvant therapy.\n\nID: 38826102\nTitle: The ameliorative and neuroprotective effects of dietary fibre on hyperuricaemia mice: a perspective from microbiome and metabolome.\nAbstract: The effect of single dietary fibre (DF) on lowering uric acid (UA) level has been reported in the literature. However, the potential protective mechanism of DF against potassium oxybate-induced hyperuricaemia (HUA), as modelled by prophylactic administration, remains unclear. The data demonstrate that DF significantly decreased serum and cerebral tissue UA concentrations, inhibited xanthine oxidase expression and activity in the liver and reduced levels of creatinine and urea nitrogen in the serum. Additionally, it mitigated the deposition of amyloid-\u03b2 in cerebral tissue. Correlation analysis showed that DF modulated the Toll-like receptor 4/NF-\u03baB signalling pathway, attenuating oxidative stress and inflammatory responses in HUA mice. Additionally, DF helps to maintain the composition of the gut microbiota, reducing harmful Desulfovibrio and enriching beneficial Akkermansia and Ruminococcus populations. The results of the faecal metabolomics analysis indicate that DF facilitates the regulation of metabolic pathways involved in oxidative stress and inflammation. These pathways include pyrimidine metabolism, tryptophan metabolism, nucleotide metabolism and vitamin B6 metabolism. Additionally, the study found that DF has a preventive effect on anxiety-like behaviour induced by HUA. In summary, DF shows promise in mitigating HUA and cognitive deficits, primarily by modulating gut microbiota and metabolites.\n\nID: 38768838\nTitle: Investigating the effects of rare ginsenosides on hyperuricemia and associated sperm damage via nontargeted metabolomics and gut microbiota.\nAbstract: In ancient times, ginseng was used for hyperuricemia treatment as described in the classic traditional Chinese medical text Shang Han Lun. Recent studies have shown that common ginsenosides and rare ginsenosides (RGS) are the main active compounds in ginseng. RGS have higher activity and are less studied in the treatment of hyperuricemia. To determine whether RGS prevents and ameliorates potassium oxonate(PO)-induced hyperuricemia and concomitant spermatozoa damage in mice and the possible underlying mechanisms. Potassium oxonate (PO, 300\u00a0mg/kg) induced hyperuricemia in mice via the oral administration of RGS (50, 100, or 200\u00a0mg/kg) or allopurinol (ALL, 5\u00a0mg/kg) for 35 days. Uric acid (UA) and xanthine oxidase (XO) levels were measured to assess the degree of histopathological damage in the liver, kidney, and testis, and renal creatinine (CRE), urea nitrogen (BUN), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), and inflammatory factor (IL-1\u03b2) levels were measured to calculate the sperm density. Mechanisms were also explored based on blood and urine metabolomics and the gut microbiota. In this study, we demonstrated that RGS containing Rg3, Rk1, Rg6, and Rg5 could reduce serum UA levels, inhibit serum and hepatic XO activity, reduce renal CRE and BUN levels, further restore renal SOD and GSH activities, reduce the accumulation of MDA in the kidneys, and attenuate the production of renal IL-1\u03b2. RGS was able to restore sperm density. Metabolomic analysis revealed that RGS improved sphingolipid metabolism, pyrimidine metabolism, and other metabolic pathways. 16S rDNA sequencing revealed that RGS could increase gut microbial diversity, restore the Firmicutes/Bacteroidetes (F/B) ratio, and adjust the intestinal microbial balance. Spearman's correlation analysis revealed a correlation between differentially metabolites and the gut microbiota. Lactobacillus and Akkermansia are the core genera. RGS can be a candidate for the prevention and amelioration of hyperuricemia and concomitant sperm damage. Its mechanism of action is closely related to sphingolipid metabolism, pyrimidine metabolism, and the modulation of gut microbiota, such as Lactobacillus and Akkermansia.\n\nID: 38476614\nTitle: Long access heroin self-administration significantly alters gut microbiome composition and structure.\nAbstract: It is well known that chronic opioid use disorder is associated with alterations in gastrointestinal (GI) function that include constipation, reduced motility, and increased bacterial translocation due to compromised gut barrier function. These signs of disrupted GI function can be associated with alterations in the gut microbiome. However, it is not known if long-access opioid self-administration has effects on the gut microbiome. We used 16S rRNA gene sequencing to investigate the gut microbiome in three independent cohorts (N=40 for each) of NIH heterogeneous stock rats before onset of long-access heroin self-administration (i.e., na\u00efve status), at the end of a 15-day period of self-administration, and after post-extinction reinstatement. Measures of microbial \u03b1- and \u03b2-diversity were evaluated for all phases. High-dimensional class comparisons were carried out with MaAsLin2. PICRUSt2 was used for predicting functional pathways impacted by heroin based on marker gene sequences. Community \u03b1-diversity was not altered by heroin at any of the three phases by comparison to saline-yoked controls. Analyses of \u03b2-diversity showed that the heroin and saline-yoked groups clustered significantly apart from each other using the Bray-Curtis (community structure) index. Heroin caused significant alterations at the ASV level at the self-administration and extinction phases. At the phylum level, the relative abundance of Firmicutes was increased at the self-administration phase. Deferribacteres was decreased in heroin whereas Patescibacteria was increased in heroin at the extinction phase. Potential biomarkers for heroin emerged from the MaAsLin2 analysis. Bacterial metabolomic pathways relating to degradation of carboxylic acids, nucleotides, nucleosides, carbohydrates, and glycogen were increased by heroin while pathways relating to biosynthesis of vitamins, propionic acid, fatty acids, and lipids were decreased. These findings support the view that long access heroin self-administration significantly alters the structure of the gut microbiome by comparison to saline-yoked controls. Inferred metabolic pathway alterations suggest the development of a microbial imbalance favoring gut inflammation and energy expenditure. Potential microbial biomarkers and related functional pathways likely invoked by heroin self-administration could be targets for therapeutic intervention.\n\nID: 38445660\nTitle: Shotgun metagenomics and systemic targeted metabolomics highlight indole-3-propionic acid as a protective gut microbial metabolite against influenza infection.\nAbstract: The gut-to-lung axis is critical during respiratory infections, including influenza A virus (IAV) infection. In the present study, we used high-resolution shotgun metagenomics and targeted metabolomic analysis to characterize influenza-associated changes in the composition and metabolism of the mouse gut microbiota. We observed several taxonomic-level changes on day (D)7 post-infection, including a marked reduction in the abundance of members of the Lactobacillaceae and Bifidobacteriaceae families, and an increase in the abundance of Akkermansia muciniphila. On D14, perturbation persisted in some species. Functional scale analysis of metagenomic data revealed transient changes in several metabolic pathways, particularly those leading to the production of short-chain fatty acids (SCFAs), polyamines, and tryptophan metabolites. Quantitative targeted metabolomics analysis of the serum revealed changes in specific classes of gut microbiota metabolites, including SCFAs, trimethylamine, polyamines, and indole-containing tryptophan metabolites. A marked decrease in indole-3-propionic acid (IPA) blood level was observed on D7. Changes in microbiota-associated metabolites correlated with changes in taxon abundance and disease marker levels. In particular, IPA was positively correlated with some Lactobacillaceae and Bifidobacteriaceae species (Limosilactobacillus reuteri, Lactobacillus animalis) and negatively correlated with Bacteroidales bacterium M7, viral load, and inflammation markers. IPA supplementation in diseased animals reduced viral load and lowered local (lung) and systemic inflammation. Treatment of mice with antibiotics targeting IPA-producing bacteria before infection enhanced viral load and lung inflammation, an effect inhibited by IPA supplementation. The results of this integrated metagenomic-metabolomic analysis highlighted IPA as an important contributor to influenza outcomes and a potential biomarker of disease severity.\n\nID: 38088975\nTitle: A dynamics association study of gut barrier and microbiota in hyperuricemia.\nAbstract: The intricate interplay between gut microbiota and hyperuricemia remains a subject of growing interest. However, existing studies only provided snapshots of the gut microbiome at single time points, the temporal dynamics of gut microbiota alterations during hyperuricemia progression and the intricate interplay between the gut barrier and microbiota remain underexplored. Our investigation revealed compelling insights into the dynamic changes in both gut microbiota and intestinal barrier function throughout the course of hyperuricemia. The hyperuricemia mice (HY) were given intragastric administration of adenine and potassium oxalate. Gut microbiota was analyzed by 16S rRNA sequencing at 3, 7, 14, and 21 days after the start of the modeling process. Intestinal permeability as well as LPS, TNF-\u03b1, and IL-1\u03b2 levels were measured at 3, 7, 14, and 21 days. We discovered that shifts in microbial community composition occur prior to the onset of hyperuricemia, key bacterial Bacteroidaceae, Bacteroides, and Blautia exhibited reduced levels, potentially fueling microbial dysbiosis as the disease progresses. During the course of hyperuricemia, the dynamic fluctuations in both uric acid levels and intestinal barrier function was accompanied with the depletion of key beneficial bacteria, including Prevotellaceae, Muribaculum, Parabacteroides, Akkermansia, and Bacteroides, and coincided with an increase in pathogenic bacteria such as Oscillibacter and Ruminiclostridium. This microbial community shift likely contributed to elevated lipopolysaccharide (LPS) and pro-inflammatory cytokine levels, ultimately promoting metabolic inflammation. The decline of Burkholderiaceae and Parasutterella was inversely related to uric acid levels, Conversely, key families Ruminococcaceae, Family_XIII, genera Anaeroplasma exhibited positive correlations with uric acid levels. Akkermansiaceae and Bacteroidaceae demonstrating negative correlations, while LPS-containing microbiota such as Desulfovibrio and Enterorhabdus exhibited positive correlations with intestinal permeability. In summary, this study offers a dynamic perspective on the complex interplay between gut microbiota, uric acid levels, and intestinal barrier function during hyperuricemia progression. Our study suggested that Ruminiclostridium, Bacteroides, Akkermansiaceae, Bilophila, Burkholderiaceae and Parasutterella were the key bacteria that play vital rols in the progress of hyperuricemia and compromised intestinal barrier, which provide a potential avenue for therapeutic interventions in hyperuricemia.\n\nID: 36413756\nTitle: Dietary Turmeric Consumption Alleviates Ulcerative Colitis via Restoring Tryptophan Metabolism and Alleviating Gut Microbiota Dysbiosis in Mice.\nAbstract: This study was designed to first verify the protective capacity of turmeric powder (TP) as a traditional cooking spice against dextran sulfate sodium (DSS)-induced intestinal inflammation and intestine microbiota imbalance. The DSS-induced mice were fed a standard rodent chow supplemented with or without TP (8%) for 37 days. The results indicated that the pathological phenotype, gut barrier disruption, and colon inflammation of DSS-induced mice were significantly improved through supplementation of TP. In addition, 16S rRNA-based microbiota or targeted metabolomics analysis indicated that TP ameliorated intestinal microbiota dysbiosis caused by DSS and particularly enhanced the abundances of probiotics correlated with tryptophan metabolism, such as Lactobacillus and Bifidobacterium, where the cecal tryptophan was metabolized to indole-3-propionic acid and indole-3-acetic acid. Consumption of TP markedly enhanced the expression levels of colonic aromatic hydrocarbon receptors and further increased the expressions of intestinal tight junction proteins and interleukin-22 in the colitis mice. Collectively, these findings manifest the protective actions of dietary TP consumption against ulcerative colitis via restoring the intestinal microbiota disorders, promoting microbial metabolism, and improving intestinal barrier damage.\n\nID: 36374311\nTitle: Live and pasteurized Akkermansia muciniphila attenuate hyperuricemia in mice through modulating uric acid metabolism, inflammation, and gut microbiota.\nAbstract: Akkermansia muciniphila (A. muciniphila) has been demonstrated to exhibit beneficial effects against various metabolic diseases, but whether A. muciniphila has an anti-hyperuricemia effect remains unexplored. In this study, live and pasteurized A. muciniphila were examined for their efficacy in alleviating hyperuricemia in mice. Live and pasteurized A. muciniphila (approximately 2 \u00d7 108 CFU) were given to a hyperuricemic mice model via oral gavage for three weeks. Both forms of A. muciniphila decreased serum urate and inhibited xanthine oxidase in the liver. In addition, fecal and urinal urate was increased in both treatment groups, which corresponds to the changes in the mRNA and protein expression levels of renal uric acid-related transporters (URAT1, GLUT9, and ABCG2) and intestinal ABCG2. Both forms of bacteria reduced the mRNA expression of inflammatory factors in the liver, kidneys and colon. Live A. muciniphila enhanced the expression of tight junction proteins and improved the dysbiosis of intestinal flora. These findings suggest that both live or pasteurized A. muciniphila could effectively attenuate hyperuricemia by moderating uric acid metabolism and inflammation, and live bacteria exhibit additional beneficial effects on the gut microbiota. These findings highlight that A. muciniphila could be potentially developed as a probiotic or postbiotic to combat hyperuricemia.\n\nID: 36266751\nTitle: Berberine Attenuates Hyperuricemia by Regulating Urate Transporters and Gut Microbiota.\nAbstract: Hyperuricemia (HUA) and its associated metabolic diseases seriously threaten human health, and commensal microbiota has been identified as one of the environmental triggers of HUA.\u00a0The role of berberine (BBR) in the treatment of HUA has begun to receive attention in recent years. However, how BBR modulates the microbiota to slow HUA progression is unclear. In this study, we showed that BBR alleviated potassium oxonate (PO)-induced HUA in mice by suppressing the expression of xanthine oxidase (XOD) in the liver and urate transporter 1 (URAT1) and glucose transporter 9 (GLUT9) in the kidney. The BBR also improved renal inflammation by inhibiting the expression of TNF-[Formula: see text], IL-1[Formula: see text], and caspase-1. Subsequently, we evaluated whether the observed anti-HUA effects of BBR were associated with changes in gut microbial structure in mice. 16S rRNA sequencing data showed that BBR significantly altered the community compositional structure of the gut microbiota. Specifically, BBR enriched the abundance of Coprococcus, Bacteroides, Akkermansia, and Prevotella. Antibiotic treatment can reverse the anti-HUA effects of BBR that further supports the role of the gut microbiota. In conclusion, our study provides evidence that BBR ameliorates PO-induced HUA by modulating the gut microbiota.\n\nID: 36201123\nTitle: The impact of short-chain fatty acid-producing bacteria of the gut microbiota in hyperuricemia and gout diagnosis.\nAbstract: Persistent hyperuricemia is a key factor in gout; however, only 13.5% of hyperuricemic individuals manifest the disease. The gut microbiota could be one of the many factors underlying this phenomenon. We aimed to assess the difference in taxonomic and predicted functional profiles of the gut microbiota between asymptomatic hyperuricemia (AH) individuals and gout patients. The V3-V4 region of the 16S rRNA gene of the gut microbiota of AH individuals, gout patients, and controls was sequenced. Bioinformatic analyses were carried out with QIIME2 and phyloseq to determine the difference in the relative abundance of bacterial genera among the study groups. Tax4fun2 was used to predict the functional profile of the gut microbiota. AH individuals presented a higher abundance of butyrate- and propionate-producing bacteria than gout patients; however, the latter had more bacteria capable of producing acetate. The abundance of Prevotella genus bacteria was not significantly different between the patients but was higher than that in controls. This result was corroborated by the functional profile, in which AH individuals had less pyruvate oxidase abundance than gout patients and less abundance of an enzyme that regulates glutamate synthetase activation than controls. We observed a distinctive taxonomic profile in AH individuals characterized by a higher abundance of short-chain fatty acid-producing bacteria in comparison to those observed in gout patients. Furthermore, we provide scientific evidence that indicates that the gut microbiota of AH individuals could provide anti-inflammatory mediators, which prevent the appearance of gout flares. Key Points \u2022 AH and gout patients both have a higher abundance of Prevotella genus bacteria than controls. \u2022 AH individuals' gut microbiota had more butyrate- and propionate-producing bacteria than gout patients. \u2022 The gut microbiome of AH individuals provides anti-inflammatory mediators that could prevent gout flares.\n\nID: 35913271\nTitle: Exposure to particulate matter 2.5 leading to lung microbiome disorder and the alleviation effect of Auricularia auricular-judae polysaccharide.\nAbstract: The aim of the paper is to explore the role of lung microbiome disorder in lung tissue injury induced by exposure to particulate matter with a maximum diameter of 2.5 \u03bcm (PM2.5) and the alleviation effect of Auricularia auricular-judae polysaccharide (AAP). Sprague Dawley rats were given PM2.5 suspension at a dose of 20 mg/l twice a week for 8 weeks. Then, 100 mg/kg or 200 mg/kg of AAP was administered to the rats after PM2.5 exposure. The bronchoalveolar lavage fluid (BALF) and lung tissue samples were collected at the end of the experiment. The BALF was meant to detect changes in lung microbiome by 16S sequences and cluster analysis, with the application of the principal component analysis and the partial least squares discriminant analysis. The levels of interferon-\u03b3 (IFN-\u03b3), and interleukin (IL)-4, IL-8, and IL-10 in lung tissue were detected by the enzyme-linked immunosorbent assay method. The pathological changes in lung tissue were observed by hematoxylin and eosin staining. After PM2.5 exposure, the alveolar septum was widened, and the structures of alveolar walls were destroyed. There was inflammatory cells infiltration in the alveolar space and the interstitial space. Alpha diversity in BALF showed that the Chao1, ACE, Simpson, and Shannon values were increased, and the lung microbiome analysis revealed that the relative abundance of Firmicutes and Clostridium increased, while the relative abundance of Bacteroidetes and Akkermansia decreased. The contents of IFN-\u03b3 and IL-8 in lung tissue increased while the content of IL-10 decreased. After the administration of AAP, the alveolar structure damage was alleviated, and the interstitial hemorrhage, edema, and inflammatory cells infiltration were reduced. The Chao1 and ACE values decreased, and the taxonomic abundance values of Akkermansia were much higher. Simultaneously, the contents of IFN-\u03b3, IL-4, and IL-8 decreased, and the content of IL-10 increased. It was found that PM2.5 resulted in lung microbiome disorder, which might lead to the inflammation of lung tissue. It was also revealed that AAP could alleviate the inflammatory damage of lung tissue induced by PM2.5.

Previous studies have associated antimicrobial use with allergies, but the real impact of antibiotics on asthma is still elusive. We investigated the potential impact of amoxicillin (Amox), trimethoprim/sulfamethoxazole (TMP/SMX), and metronidazole (Metro) in a murine model of OVA-induced allergic airway inflammation. BALB/c mice received three cycles of 7 days of antibiotics in drinking water followed by 7 days washout and were sensitized i.p. with OVA/Alum at days 0 and 14. After the end of the last antibiotic washout, the mice were challenged with aerosolized OVA. Pulmonary parameters were evaluated, and serum, BAL, and feces were collected for analysis. Amox- and TMP/SMX-treated animals displayed more severe allergic airway inflammation parameters with increased airway hyperresponsiveness, reduced lung alveolar volume, and increased levels in BAL of IL-4 and IL-6. In contrast, Metro-treated mice showed preserved FEV-50, decreased lung inflammation, and higher levels of butyrate and propionate in their feces. Metro treatment was associated with increased OVA-specific IgA in serum. BAL microbiota was abundant in allergic groups but not in nonallergic controls with the Amox-treated group displaying the increased frequency of Proteobacteria, while Metro and TMP/SMX showed increased levels of Firmicutes. In the gut, we observed the enrichment of Akkermansia muciniphila associated with reduced airway inflammation phenotype in the Metro group, even after the recovery period. Our data suggest that different antibiotic treatments may impact the course of experimental allergic airway inflammation in diverse ways by several mechanisms, including modulation of short-chain fat acids production by intestinal microbiota.\n\nID: 35752076\nTitle: Simiao Wan modulates the gut microbiota and bile acid metabolism during improving type 2 diabetes mellitus in mice.\nAbstract: Gut microbiota coupled with their metabolites (bile acids, BAs) get involved in diabetic pathogenesis. Simiao Wan is a famous traditional Chinese formula consisting on Phellodendron chinense C.K.Schneid. (Rutaceae), Atractylodes lancea (Thunb.) DC. (Asteraceae), Achyranthes bidentata Blume (Amaranthaceae) and Coix lacryma-jobi var. ma-yuen (Rom.Caill.) Stapf (Poaceae), and used to treat gouty arthritis and hyperuricemia for thousands of years. However, the mechanisms underlying its beneficial efficacy on diabetes still needs to be explored. Our study was performed to reveal the effects of the 75% ethanol extraction of Simiao Wan (SMW) on diabetes, gut microbiota and bile acids (BAs) in diabetic mice. The effects of SMW on diabetes were evaluated in mice treated by high-fat diet (HFD)/streptozotocin (STZ). The 16S rDNA sequencing and BAs metabolomics were performed to assess the changes of BAs profiles and gut microbiota induced by SMW. Western blot and real-time quantitative PCR were conducted to evaluate the possible mechanism of SMW. SMW significantly improved insulin resistance and hepatic lipid accumulation in HFD/STZ mice. It remarkably enriched in the bacteria Allobaculum, Clostridium, Akkermansia, Lactobacilus and Bilophila whereas decreased Coprococcus and Halomonas in diabetic mice. Furthermore, the profiles of BAs were also modulated by SMW, indicated by the reduction of conjugated BAs and 12\u03b1-OH/non-12\u03b1-OH BAs ratio in liver as well as the increase of primary BAs in feces. SMW also activated farnesoid X receptor and inhibited sterol regulatory element-binding protein-1 expression, contributing to its beneficial actions on lipid accumulation in liver. Our results showed that SMW exerted its beneficial effects on insulin resistance and hepatic lipid accumulation indirectly through regulating profiles of gut microbe and BAs.\n\nID: 35274663\nTitle: Novel anti-hyperuricemic hexapeptides derived from Apostichopus japonicus hydrolysate and their modulation effects on the gut microbiota and host microRNA profile.\nAbstract: Hyperuricemia (HUA) is the second most common metabolic disease nowadays, and is characterized by permanently increased concentrations of serum uric acid. In this study, two novel hexapeptides (GPAGPR and GPSGRP) were identified from Apostichopus japonicus hydrolysate and predicted to have xanthine oxidase (XOD) inhibitory activity by molecular docking. Their in vitro XOD inhibition rates reached 37.3% and 48.6%, respectively, at a concentration of 40 mg mL-1. Subsequently, in vivo experiments were carried out in a HUA mouse model, and we found that both peptides reduced the serum uric acid by inhibiting uric acid biosynthesis and reabsorption, as well as alleviated renal inflammation via suppressing the activation of the NLRP3 inflammasome. 16S rDNA sequencing indicated that both peptide treatments reduced the richness and diversity of the gut microbiota, altered the composition in the phylum and genus levels, but different change trends were observed in the phylum Verrucomicrobia and genera Akkermansia, Dubosiella, Alloprevotella, Clostridium unclassified and Alistipes. In addition, changes in the renal microRNA (miRNA) profiles induced by GPSGRP treatment were analyzed; 21 differentially expressed (DE) miRNAs were identified among groups, and KEGG pathway analysis indicated that their potential target genes were involved in pluripotency of stem cell regulation, mTOR signaling pathway and proteoglycans. Moreover, ten miRNAs involved in the HUA onset and alleviation were identified, which showed a high correlation with genera related to the metabolism of short-chain fatty acids, bile acids and tryptophan. This study delineated two hexapeptides as potential microbiota modulators and miRNA regulators that can ameliorate HUA.\n\nID: 35265071\nTitle: The Ability of Resveratrol to Attenuate Ovalbumin-Mediated Allergic Asthma Is Associated With Changes in Microbiota Involving the Gut-Lung Axis, Enhanced Barrier Function and Decreased Inflammation in the Lungs.\nAbstract: Asthma is a chronic respiratory disease highly prevalent worldwide. Recent studies have suggested a role for microbiome-associated gut-lung axis in asthma development. In the current study, we investigated if Resveratrol (RES), a plant-based polyphenol, can attenuate ovalbumin (OVA)-induced murine allergic asthma, and if so, the role of microbiome in the gut-lung axis in this process. We found that RES attenuated allergic asthma with significant improvements in pulmonary functions in OVA-exposed mice when tested using plethysmography for frequency (F), mean volume (MV), specific airway resistance (sRaw), and delay time(dT). RES treatment also suppressed inflammatory cytokines in the lungs. RES modulated lung microbiota and caused an abundance of Akkermansia muciniphila accompanied by a reduction of LPS biosynthesis in OVA-treated mice. Furthermore, RES also altered gut microbiota and induced enrichment of Bacteroides acidifaciens significantly in the colon accompanied by an increase in butyric acid concentration in the colonic contents from OVA-treated mice. Additionally, RES caused significant increases in tight junction proteins and decreased mucin (Muc5ac) in the pulmonary epithelium of OVA-treated mice. Our results demonstrated that RES may attenuate asthma by inducing beneficial microbiota in the gut-lung axis and through the promotion of normal barrier functions of the lung.\n\nID: 35259052\nTitle: Lacticaseibacillus paracasei sh2020 induced antitumor immunity and synergized with anti-programmed cell death 1 to reduce tumor burden in mice.\nAbstract: The gut microbiota was emerging as critical regulatory elements in shaping the outcome of cancer immunotherapy. However, the underlying mechanisms by which the gut commensal species enhance antitumor immunity remain largely unexplored. Here, we show that the gut microbiota from healthy individuals conferred considerable sensitivity to anti-PD-1 in the colorectal cancer (CRC) tumor-bearing mice, whereas gut microbiota from CRC patients failed to do so. By 16S rRNA gene sequencing, we identified Lactobacillus that was significantly increased in the mice with good response to anti-PD-1, and significantly correlated with anti-tumor immunity. After a series of screening, we isolated a novel Lacticaseibacillus strain, named L. paracasei sh2020. L. paracasei sh2020 showed the most notable anti-tumor immunity in the mice with gut dysbiosis. Mechanistically, the antitumor immune response elicited by L. paracasei sh2020 was dependent on CD8+ T cell. In vitro and in vivo studies revealed that L. paracasei sh2020 stimulation triggered the upregulated expression of CXCL10 in the tumors and subsequently enhanced CD8+ T cell recruitment. Meanwhile, the modulation of gut microbiota caused by L. paracasei sh2020 enhanced its antitumor effect and gut barrier function. Overall, our study offered novel insights into the mechanism by which gut microbiota shaped the outcome of cancer immunotherapy and, more importantly, the novel strain L. paracasei sh2020 might serve as an easy and effective way to promote anti-PD-1 effect in clinical practice.\n\nID: 42511204\nTitle: Postbiotics in Functional Foods: Preparation-Based Characterization, Gut-Brain Axis Interactions, and Translational Perspectives.\nAbstract: Postbiotics are defined as preparations of inanimate microorganisms and/or their components that confer a health benefit on the host. Although interest in postbiotics has increased substantially, their translational use in functional foods remains insufficiently characterized with respect to preparation identity, production methodology, food-matrix compatibility, mechanistic specificity, and regulatory positioning. This PRISMA-guided structured review aims to synthesize current evidence on postbiotics in functional food and nutraceutical contexts, with particular emphasis on preparation-based characterization, gut-brain axis-related mechanisms and clinical findings, food matrix applicability, and regulatory and health-claim considerations. Unlike broader postbiotic reviews that mainly address definitions, general health effects, or technological stability, this review integrates preparation identity, production process, gut-brain axis-related evidence, food matrix compatibility, and regulatory/health-claim translation within a single functional food framework. A structured literature search was conducted in Scopus and Web of Science Core Collection and was completed on 16 February 2026. The search strategy included three conceptual blocks: postbiotic and inactivation-based preparation terms, functional food/nutraceutical and food matrix terms, and gut-brain axis-related clinical and mechanistic terms. Cosmetic, topical, veterinary, animal feed, and aquaculture-focused publications were excluded. The export files contained 131 records from Scopus and 136 from the Web of Science Core Collection, yielding 267 records after applying document-type and language filters. After manually removing duplicates, 237 unique records were screened. Following title/abstract screening, 176 records were excluded as outside the scope of the review, and 61 publications were retained for full-text assessment and final thematic synthesis. The review was reported according to applicable PRISMA 2020 items. The evidence was organized into three thematic domains: gut-brain axis-related clinical findings, mechanistic evidence, and food matrix/product development applications. Heat-inactivated preparations, including Lactobacillus gasseri CP2305 and Lactiplantibacillus plantarum SNK12, have shown preliminary effects on stress-related symptoms, sleep quality, and selected neuroendocrine or inflammatory biomarkers in human studies. Mechanistic pathways include gut barrier integrity, immunomodulation, short-chain fatty acid signaling, tryptophan-kynurenine-serotonin metabolism, vagal communication, and regulation of the hypothalamic-pituitary-adrenal axis. Food matrix studies support the potential application of postbiotics in fermented dairy products, cereal-based systems, plant-based matrices, powders, concentrates, and bioactive packaging; however, matrix-dependent effects on bioavailability, sensory quality, and biological activity remain incompletely defined. Postbiotics provide a stable translational platform for functional-food development, but their scientific and commercial use requires clear characterization of the microbial source, production process, inactivation method, retained active fractions, dose metric, delivery matrix, and clinically meaningful endpoint. Future studies should avoid broad category-level claims and prioritize preparation- and matrix-defined human evidence with standardized safety reporting.\n\nID: 42436039\nTitle: Fermentation of plant-based foods: Microbial consortia and their impacts on composition, sensory quality, and health benefits of food products.\nAbstract: Fermented plant-based foods have obtained growing interests for their improved nutrition profile, enhanced flavor and taste, as well as their health-promoting properties. Fermentation using lactic acid bacteria (LAB) and yeasts can eliminate antinutritional components and off-flavor compounds present in plant matrices while also generating beneficial metabolites. The interaction between fermentative microbes and plant substrates is dependent on plant matrices, microbial strains, and processing conditions. Accumulating evidence indicates that fermentation modifies the generation, degradation, and bioavailability of food bioactive compounds such as bioactive peptides, vitamins, volatiles, phenolics, phytic acid and phytates, saponins, and raffinose-family oligosaccharides. This chapter reviews and critically examines research data on microbial transformations of bioactive compounds in fermented plant matrices and pinpoints key factors contributing to inconsistent findings. It also identifies key research directions for understanding and applying fermentation-driven changes to improve the nutritional and functional quality of plant-based fermented foods.\n\nID: 42436034\nTitle: Legume fermentation: Nutritional benefits and emerging applications.\nAbstract: Legumes are increasingly recognized as strategic plant-based ingredients due to their high content of proteins with good biological value, dietary fibers, minerals, oligosaccharides, and phenolic compounds. However, their broader use in food formulations is often limited by the presence of anti-nutritional factors (ANF) and other compounds that may negatively affect digestibility, technological performance, and sensory acceptability. In recent years, different technological and biotechnological strategies have been explored to enhance the nutritional and functional properties of legumes and legume-derived ingredients. Among these approaches, fermentation has emerged as a particularly effective and sustainable process widely applied in several traditional food systems. The use of selected lactic acid bacteria and fermentation processes inspired by sourdough technology has demonstrated a strong ability to reduce ANF, improve protein digestibility and nutrient bioavailability, and enhance the technological and sensory characteristics of legume flours and grains. In addition, fermentation contributes to improving food safety through the inhibition or transformation of spoilage microorganisms, pathogens, and toxic compounds. Beyond their direct consumption, fermented legumes are also key components of many traditional foods and can be successfully incorporated into innovative formulations of staple products, including baked goods and pasta, leading to foods with improved nutritional, functional, and shelf-life properties.\n\nID: 42354217\nTitle: The Potential for Bioactive Peptide Production in a Fermented Dairy Beverage Based on Chickpea Water Extract Using Proteolytic Lactic Acid Bacteria.\nAbstract: A chickpea-based milk beverage containing both plant and animal proteins represents an excellent substrate for the production of biologically active peptides through fermentation. Fermentation by lactic acid bacteria (LAB) increases its nutritional value compared to the unfermented beverage while improving the digestibility and bioavailability of essential nutrients via proteolytic enzyme activity. This study investigated the production of bioactive peptides in fermented chickpea water extract using ten bacterial strains isolated from plant and animal sources. The proteolytic activity of each strain was quantified using the trinitrobenzene sulfonic acid (TNBS) method, and the presence of proteolytic genes was confirmed via agarose gel electrophoresis. Peptides released during fermentation were identified through two-dimensional electrophoresis, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and tandem mass spectrometry. To predict the potential biological activities of the studied peptide sequences, a series of in silico analyses were performed using specialized bioinformatics tools. The identified peptides were predicted to exhibit antioxidant, antihypertensive, anticancer, antibacterial, antifungal, antituberculosis, and angiotensin-converting enzyme (ACE) inhibitory activities. Based on the results, L. fermentum SB-2 and L. sakei SD-8, were selected as promising candidates for bioactive peptide production in a chickpea water extract-based milk beverage and were subsequently applied in the beverage prototype.\n\nID: 42286603\nTitle: Probiotic supplementation reduces IL-6 and improves clinical outcomes in patients with mild-to-moderate COPD: a randomized placebo-controlled trial.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent inflammation and progressive airflow limitation. Emerging evidence highlights the gut-lung axis as a potential therapeutic target, with probiotics proposed to modulate Th17-related inflammatory pathways. In this randomized, double-blind, placebo-controlled trial, 50 patients with mild-to-moderate COPD were enrolled; 44 completed the 8-week intervention (23 probiotics, 21 placebo). Participants received either a multistrain probiotic formulation or placebo. Outcomes included spirometry, COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and serum IL-6, IL-17, and TGF-\u03b2 levels. Probiotic supplementation significantly improved FEV1 and FVC within the intervention group, although between-group spirometric differences were not significant. IL-6 levels declined significantly following probiotic therapy, with a significantly greater reduction compared to placebo, whereas IL-17 and TGF-\u03b2 remained unchanged. CAT scores improved significantly in the probiotic group, exceeding the minimal clinically important difference and demonstrating a significant between-group effect. No significant change was observed in mMRC scores. Eight weeks of probiotic supplementation was associated with reduced systemic IL-6 levels and clinically meaningful improvement in patient-reported outcomes in mild-to-moderate COPD. These findings support a potential adjunctive role for probiotics and warrant larger mechanistic trials.

This study aimed to systematically analyse literature on TCM nursing interventions for COPD complicated by GI dysfunction, using bibliometric methods to identify research trends, thematic structures, and future research directions. This study conducted a bibliometric analysis of relevant literature. Publications from 2015 to 2025 on TCM nursing for COPD with GI dysfunction were retrieved from the Web of Science, PubMed, Scopus, and China National Knowledge Infrastructure. After removing duplicates, 1,563 relevant publications were analysed. Bibliographic data were extracted and analysed using CiteSpace, VOSviewer, and bibliometrix (R package). Annual publication volume exhibited steady growth, peaking in 2024. China emerged as the primary research contributor, collaborating extensively with the USA, Australia, and European nations. Institutional analysis revealed key research centres predominantly located in China, with increasing international cooperation. Core authors, such as Chen Wang and Ke Huang, significantly influenced research collaboration networks. Major thematic clusters included pulmonary rehabilitation, quality of life improvement, gut-lung interactions, and molecular mechanisms. Landmark references reflected the growing integration of TCM nursing into conventional COPD care and the increasing attention on patient-centred outcomes. Research in this niche is increasingly oriented towards rehabilitation-focused integrative care and mechanism-informed perspectives (gut-lung axis). Future studies should prioritise a GI-inclusive core outcome set, standardised reporting of nursing-deliverable TCM modalities, and pragmatic/hybrid effectiveness-implementation designs aligned with gut-lung-related hypotheses.\n\nID: 42244886\nTitle: The Role of Microbiota Homeostasis in the Progression and Treatment of Chronic Obstructive Pulmonary Disease.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a heterogeneous chronic respiratory disorder characterized by persistent airflow obstruction. Its high morbidity and mortality have posed a substantial public health burden, with current symptomatic treatments exhibiting inadequate control and potential adverse effects. With advances in microecological research techniques, the critical role of microbial homeostasis in the oral cavity, lungs, and gut in respiratory health has become increasingly prominent, and microbial dysbiosis is closely associated with progression and therapeutic outcomes of COPD. This review summarizes the compositional alterations of oral, lung, and gut microbiota in COPD patients, analyzes the interactions of the oral-lung axis and gut-lung axis, and delineates three mechanisms through which microbial dysbiosis promotes COPD progression: pathogenic bacterial migration, abnormal metabolite production and immune dysregulation. Additionally, this review summarizes Western and traditional Chinese medicine interventions targeting microbiota homeostasis, including antibiotics, microecological preparations, and herbal medicines, which have shown potential in improving COPD clinical outcomes. This review aims to provide a theoretical reference for the clinical diagnosis and management of COPD. Millions of people worldwide live with chronic obstructive pulmonary disease (COPD), which brings persistent breathing struggles that disrupt their daily living. Current standard treatments mainly relieve symptoms, but have limited effects on controlling disease progression, and may cause unwanted side effects. Mounting research shows that microbes in the mouth, lungs and gut play a critical role in maintaining lung health, while their imbalance can drive COPD progression. This review focused on the link between microbial balance and COPD to find new intervention ideas. We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders. We also sorted out Western and traditional Chinese medicine strategies that restore microbial balance to improve COPD treatment and quality of life. These findings show a promising strategy for COPD therapy from the perspective of regulating microbial balance.\n\nID: 42243780\nTitle: Emphysema severity-associated gut microbiota modulates smoke-induced emphysema: evidence from fecal microbiota transplantation.\nAbstract: Cigarette smoking is the key risk factor for chronic obstructive pulmonary disease, but even similar levels of smoking can result in different disease severity. We hypothesize that differences in gut microbiota and metabolites contribute to differences in emphysema severity through the gut-lung axis. In this study, we compared the microbiome and metabolome among non-emphysema, non-severe emphysema and severe emphysema groups. Additionally, the impact of fecal microbiota transplantation from non-emphysema, non-severe emphysema and severe emphysema groups on emphysema were investigated. A total of 78 participants with a smoking history were included in this study and categorized into three groups: non-emphysema, non-severe emphysema, and severe emphysema. Gut microbiota and metabolites were analyzed, and germ-free mice underwent fecal microbiota transplantation with feces from donors representative of each group prior to smoking exposure. Significant differences in gut microbiota and metabolites were observed among the groups, with lower acetic acid levels in patients with severe emphysema, and a greater abundance of Prevotellaceae and Megasphaera in patients without emphysema. Fecal microbiota transplantation from donors with severe emphysema worsened lung pathology in mice subjected to smoking exposure, whereas fecal microbiota transplantation from donors without emphysema attenuated emphysema development. Gut microbiota and metabolites in participants with a smoking history differ according to the presence of emphysema and its severity, and can affect emphysema development. This suggests a role for gut microbiota in lung disease and provides a foundation for exploring gut microbiota as a potential therapeutic target for chronic obstructive pulmonary disease.\n\nID: 42196196\nTitle: Characteristics of Gut Microbiota in Patients with Chronic Obstructive Pulmonary Disease Based on Metagenomics and Metabolomics.\nAbstract: The gut-lung axis is important in Chronic Obstructive Pulmonary Disease (COPD) pathogenesis; however, most studies rely on low-resolution 16S rRNA sequencing, and integrated multi-omics investigations in Chinese COPD populations are scarce. A total of 104 participants including 74 stable COPD patients and 30 healthy controls from northern China were recruited, and shotgun metagenomic sequencing and untargeted metabolomics were performed. Results showed that alpha diversity of the gut microbiota did not differ significantly between COPD patients and healthy controls, whereas beta diversity showed clear separation. Marked differences in microbial composition from phylum to species levels (e.g., Oscillospiraceae) and altered microbial functions (signal transduction, antibiotic resistance, etc.) were observed in COPD patients. Metabolomic profiling identified 497 differential fecal metabolites and 1260 differential serum metabolites in COPD patients. Importantly, serum riboflavin levels were significantly reduced and positively correlated with pulmonary function indices as well as the key differential gut microbial functional gene K11752. Serum metabolite eremopetasinorol exhibited high diagnostic accuracy for COPD (AUC = 0.947, 95% CI: 0.8-0.98), surpassing fecal metabolites and microbial features. This study provides integrated metagenomic and metabolomic characterization of gut microbiota alterations in Chinese COPD patients, offering novel insights for biomarker discovery and targeted intervention strategies.\n\nID: 42169007\nTitle: Baicalein mitigates epithelial barrier impairment and microbiota dysbiosis in allergic asthmatic mice via the gut\u2011lung axis.\nAbstract: Allergic asthma (AA) may result in repeated episodes of chest constriction and coughing. In its most serious manifestations, it can cause death by asphyxiation. Currently, no efficacious therapeutic interventions exist to avert or counteract these serious outcomes. Baicalein (BAI) is a core quality marker of the traditional Chinese medicine Scutellaria baicalensis, but the mechanism of its oral action remains unclear. Assess the therapeutic efficacy of BAI in AA mice models and investigate its mechanism of action. Evaluate the efficacy of BAI on ovalbumin-induced AA mice. To assess alterations in the pulmonary and gut microbial communities, 16S rRNA sequencing was employed. The integrity and restoration of the lung and intestinal epithelial lining were evaluated via immunohistochemistry. Furthermore, gas chromatography-mass spectrometry quantified fecal levels of short-chain fatty acids (SCFAs) in AA mice, and flow cytometry was used to analyze the content of ILC2 cells in colon tissue. Finally, the role of beneficial bacteria and their metabolites in inhibiting AA was further confirmed through fecal microbiota transplantation (FMT). Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins. Moreover, BAI mitigated colonic epithelial damage, inhibited ILC2s activation in the colon, enriched the abundance of gut probiotics capable of producing SCFAs, especially Akkermansia muciniphila (A. muciniphila), and increased the content of SCFAs such as propionic acid in feces. The FMT experiment conducted after gavage with broad-spectrum antibiotics confirmed that BAI mediated reversal of microbial dysbiosis plays a key role in the treatment of AA, significantly increasing the expression of GPR41 mRNA in colon tissue and inhibiting the activation of ILC2s. The potential prebiotic BAI mitigates AA via targeting A. muciniphila and its metabolites, which consequently inhibits epithelial damage and type 2 immune activation.\n\nID: 42131229\nTitle: Mechanisms by which complex carbohydrates influence immune imbalance in COPD via the gut-lung axis: from colonic fermentation to pulmonary immune responses.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized not only by local airway inflammation and tissue injury, but also frequently by persistent systemic immune imbalance. After entering the colon, complex carbohydrates can be converted by the gut microbiota into gut-derived molecules such as short-chain fatty acids (SCFAs) and tryptophan metabolites, which may further influence the pulmonary immune status in COPD. These effects are mainly related to the regulation of colonic fermentation kinetics and metabolite production by substrate structure, as well as to the actions of selected metabolites on pulmonary immune cells and airway epithelium after intestinal absorption and systemic distribution. The monosaccharide composition, glycosidic linkage type, degree of branching, and degree of polymerization of complex carbohydrates can affect colonic fermentation kinetics and further alter the production ratio of SCFAs and tryptophan metabolites. SCFAs are the main candidate metabolites linked to the regulation of aberrant neutrophil recruitment, alveolar macrophage inflammatory status, the Treg/Th17 balance, and airway epithelial barrier integrity; selected tryptophan metabolites are mainly involved in mucosal defense and epithelial repair. In COPD, bile acids are more likely to be associated with microaspiration from gastroesophageal reflux and local microecological alterations. Complex carbohydrates may participate in the regulation of immune imbalance in COPD by affecting the production, distribution, and local pulmonary actions of gut-derived metabolites, but the quantitative relationships among these processes across the gut, blood, and lung, as well as their specific pulmonary effects in COPD, still require further clarification, particularly in human studies with synchronized sampling.\n\nID: 42110505\nTitle: Potential Benefits of Gut Microbiota Modulation in Chronic Obstructive Pulmonary Disease.\nAbstract: The gut-lung axis is increasingly recognized. This study aimed to find out whether and how the gut microbiome involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Gut microbiota was characterized via 16S rRNA gene sequencing in COPD patients and a smoking-induced mouse model. Gut dysbiosis was induced by antibiotic cocktail (ABX) and restored by fecal microbiota transplantation (FMT). Plasma metabolomics was conducted using liquid chromatography-mass spectrometry (LC-MS), and pathway analysis was performed with MetaboAnalyst 5.0. Differentially expressed genes were identified by RNA sequencing and functionally interpreted through gene set enrichment analysis (GSEA). Both COPD patients and mice showed altered gut microbiota, characterized by a unique microbial composition and reduced diversity. ABX induced gut dysbiosis exacerbated pathological lung changes, impaired lung function, and promoted Treg cell exhaustion in COPD mice. Restoration of gut homeostasis via FMT attenuated these alterations. Higher plasma levels of acetylcholine (ACh) were observed in COPD mice, while the highest ACh levels were found in ABX treated COPD mice compared to controls. Notably, ACh levels correlated positively with genus Parasutterella, which was more abundant in COPD mice, and inversely with genera Candidatus Saccharimonas and Lactobacillus, which were predominant in control mice. Metabolomic pathways analysis revealed enrichment in unsaturated fatty acids biosynthesis and purine metabolism in COPD mice relative to controls. These findings highlight the involvement of the gut microbiome in COPD development and suggest that maintaining gut homeostasis may represent a novel therapeutic strategy for COPD.\n\nID: 42099600\nTitle: The gut-lung axis: pathological crosstalk and inter-organ communication in chronic obstructive pulmonary disease and inflammatory bowel disease.\nAbstract: The significant bidirectional comorbidity risk and extensive subclinical involvement observed between chronic obstructive pulmonary disease (COPD) and inflammatory bowel disease (IBD) underscore the pivotal role of the \"gut-lung axis\" in cross-organ pathological crosstalk. Here, we comprehensively review the molecular and immunological mechanisms driving this comorbidity. Genome-wide association studies (GWAS) have substantiated genetic pleiotropy that underpins a shared susceptibility to mucosal defense deficits. The \"common mucosal immune system\" (CMIS), rooted in embryonic homology, constitutes the anatomical basis for this pathological interplay, wherein aberrant immune cell homing, Th17/Treg imbalance, and the cross-organ trafficking of innate lymphoid cells (ILCs) mediate the distal dissemination of inflammation. Furthermore, gut dysbiosis-induced depletion of short-chain fatty acids (SCFAs), acting in concert with systemic hypoxia and the IL-23/IL-17 axis, potentiates synergistic injury to the gut-lung barriers. We highlight the reciprocal, bidirectional causality of this \"hypoxic loop\" and its testable mechanistic predictions for barrier dysfunction. Furthermore, we evaluate pharmacological evidence from drug repositioning, alongside a critical examination of the \"hidden axis\" of clinical therapies as profound iatrogenic confounders. Elucidating these mechanisms is critical for establishing systemic diagnostic and therapeutic strategies; interventions targeting shared molecular targets and the microbiota hold promise for achieving a simultaneous treatment approach for these distinct pathologies.\n\nID: 42062386\nTitle: The gut mycobiome and inter-kingdom microbial networks are linked to COPD severity in lung cancer patients.\nAbstract: Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a systemic disorder affecting host\u2013microbiome interactions beyond the airways. Although bacterial alterations in COPD have been documented, the gut mycobiome and its ecological integration with bacterial communities remain unexplored. In this study, we profiled the gut mycobiome of 61 non-small-cell lung cancer (NSCLC) patients stratified by COPD severity using ITS2 sequencing and analyzed 47 overlapping patients with available metagenomic data to construct cross-kingdom bacterial\u2013fungal networks. Alpha diversity, assessed by Shannon, Simpson, and Chao1 indices, did not differ significantly between patients with and without severe COPD. Partial least squares discriminant analysis (PLS-DA) revealed partial separation of the two groups, with COPD severity explaining 6% of overall compositional variance (R\u00b2=0.06, p\u2009=\u20090.058). COPD-severe patients exhibited a significantly reduced Ascomycota/Basidiomycota ratio (p\u2009=\u20090.039) and lower relative abundance of Mucoromycota. Analysis of compositions of microbiomes (ANCOM) identified Myrothecium and Lasiodiplodia crassispora enriched in severe COPD, while Helotiales_unclassified and Phallus atrovolvatus were more abundant in non-severe cases. Fungal co-occurrence networks demonstrated reduced connectivity and modularity in severe COPD compared with non-severe COPD. Cross-kingdom analyses integrating bacterial genera revealed strengthened Candida\u2013Enterococcus/Clostridium hubs and weakened Faecalibacterium/Roseburia\u2013yeast associations in severe disease. Keystone analysis showed increased centrality for Candida, Aspergillus, Enterococcus, and Clostridium, and decreased centrality for Akkermansia and Roseburia. A compositional balance classifier achieved high discriminatory power (AUC\u2009=\u20090.88) in distinguishing COPD-severe from non-severe patients. These findings indicate that COPD severity is not characterized by major diversity loss but by guild-specific compositional shifts and extensive network rewiring, favoring oxygen-tolerant, opportunistic taxa over short-chain fatty acid\u2013associated commensals.\n\nID: 42046064\nTitle: SCFAs inhibited NETosis to alleviate lung inflammation in COPD: a potential role for GPR43.\nAbstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and poses a significant socioeconomic burden attributable to its high mortality and morbidity. Short-chain fatty acids (SCFAs), as the key metabolites produced by gut microbiota, have been considered to be involved in the regulation of pulmonary inflammation. However, the underlying bridging mechanisms through the gut-lung axis remain elusive. METHODS: To delineate cellular heterogeneity during COPD progression, we profiled lung tissues from rats at distinct stages (Days 0, 7, 14, and 28) using scRNA-seq, followed by bulk transcriptomic analysis to pinpoint critical dysregulated pathways. Gas chromatography-mass spectrometry (GC-MS) was employed to quantify the differential SCFA levels. The protective effects of SCFAs against pulmonary inflammation in COPD were evaluated via pulmonary function testing, HE staining, and ELISA. Flow cytometry, Western blotting, immunofluorescence and scanning electron microscopy were employed to explore the mechanism of SCFAs regulating neutrophil extracellular trap (NET) formation in vitro and in vivo. Finally, metagenomic sequencing was applied to investigate the impact of SCFAs on gut microbial communities. RESULTS: ScRNA-seq demonstrated the intense immune activation during the progress of COPD, characterized by neutrophil accumulation exceeding 50% of cellular composition on the 14th day in the lung tissue. Transcriptomic analysis further pinpointed neutrophil-driven NETosis as the key pathogenic pathway. The results of GC-MS showed the significant downregulation of SCFAs represented by acetic acid and propionic acid in COPD. Exogenous supplementation with SCFAs (acetic acid and propionic acid) activated the key receptor GPR43, suppressed the expression of NETs marker proteins (NE, MPO, and CitH3) and attenuated inflammatory cytokine levels in COPD rats. Rescue experiments with NETs inducers/inhibitors and GPR43 agonists/antagonists further elucidated the regulatory mechanisms of SCFAs/GPR43 axis in COPD inflammation. Furthermore, metagenomic sequencing revealed that SCFAs reshaped the intestinal flora in COPD by enriching the abundance of beneficial bacteria. CONCLUSION: As one of the key receptors for gut microbiota-derived SCFAs, GPR43 may be involved in the process by which SCFAs alleviate pulmonary inflammation in COPD through regulating NET formation. These findings provide valuable experimental evidence for promoting the clinical translation of therapeutic strategies characterized by gut microbiota and their metabolites.\n\nID: 42040562\nTitle: Global research trends and thematic evolution of respiratory microbiota in COPD: a bibliometric study.\nAbstract: Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a disorder influenced by the respiratory microbiota. Microbial dysbiosis has been linked to disease progression, inflammation, and clinical outcomes. However, a comprehensive overview of the global research landscape and evolving themes in this field is still lacking. Publications on COPD and respiratory microbiota were retrieved from the Web of Science Core Collection (WoSCC) and Scopus databases. Bibliometric analyses, including publication trends, co-authorship networks, keyword co-occurrence, citation bursts, and thematic evolution, were conducted using VOSviewer, CiteSpace, and the bibliometrix package in R. Between 2001 and 2025, 296 publications were identified in WoSCC and 433 in Scopus, reflecting a sustained growth in research output. Keyword co-occurrence and clustering analyses revealed three main research hotspots: (1) respiratory microbiota composition and dynamics, (2) pathogen colonization and inflammation-related processes, and (3) clinically relevant outcomes. Citation burst and thematic evolution analyses demonstrated a clear temporal shift from pathogen-centered studies toward microbiota-based, dynamic, and clinically oriented research paradigms. International collaboration is increasingly prominent, with China, the USA, and the UK leading in productivity and citation impact. This bibliometric study systematically delineates the intellectual structure and evolving trends of COPD-related respiratory microbiota research. Our findings highlight the maturation of the field, reveal emerging research directions such as multi-omics integration and gut-lung axis interactions, and provide a quantitative reference for guiding future translational and microbiota-focused studies in COPD.\n\nID: 42039694\nTitle: Fermentation-Induced Changes in Phytochemical Composition and Pharmacological Activities of Zingiberaceae Plants: Insight from in vitro and in vivo Studies.\nAbstract: The Zingiberaceae family has long been used in traditional medicine due to its rich array of secondary metabolites. However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity.\n\nID: 42022800\nTitle: Longitudinal multi-omics evidence reveals lung injury and concurrent disruption of intestinal flora and serum metabolism by cigarette smoke and influenza virus.\nAbstract: Cigarette smoke (CS) exposure is the primary risk factor for chronic obstructive pulmonary disease (COPD), and respiratory viral infections, particularly influenza A virus (IAV), are major triggers of acute exacerbations of COPD (AECOPD). However, the dynamic interactions among pulmonary pathology, gut microbiota, and host metabolism during these episodes remains unclear. This study aimed to delineate the longitudinal characteristics of virus-induced AECOPD and identify potential biomarkers. Mice were exposed to cigarette smoke for eight weeks, followed by intranasal inoculation with IAV. A longitudinal assessment was conducted from day 1 to day 15 post-infection, integrating analyses of lung pathology, lung function, gut microbiome, and both serum and fecal metabolomes. Additionally, random forest modeling was employed to identify specific metabolic biomarkers associated with the acute exacerbation stage. Mice exposed to cigarette smoke and IAV exhibited significant pulmonary immune cell recruitment, impaired lung function, and emphysematous changes, peaking at day 5 post-infection. By day 15, acute airway inflammation had subsided; however, interstitial immune cell infiltration, collagen deposition, and emphysema persisted. 16S rRNA sequencing revealed dynamic shifts in gut microbiota composition, with the abundance of Intestinimonas positively correlating with pulmonary inflammatory markers. Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation. Random forest analysis identified 1-Methylnicotinamide (1-MNA) as a promising biomarker for distinguishing virus-triggered AECOPD, achieving an area under the curve (AUC) of 1.0. This study demonstrates that cigarette smoke combined with influenza infection induces persistent lung injury alongside concurrent disruption of intestinal flora and serum metabolism. The findings show that gut microbiota and metabolites are potential biomarkers and supplementation with unsaturated fatty acids may represent a novel therapeutic strategy for virus-induced AECOPD.\n\nID: 42016608\nTitle: From the gut to the lungs: The role of gut microbiota in chronic obstructive pulmonary disease and related research progress.\nAbstract: Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disease with high morbidity and mortality. Existing treatment methods are difficult to effectively curb disease progression, highlighting the urgency to explore new pathogenesis mechanisms and therapeutic targets. With the development of microbiomics, the proposal of the \"gut-lung axis\" concept has provided a brand-new perspective for understanding the pathological mechanisms of COPD, revealing that the gut and lungs maintain a close connection through pathways such as immune regulation and metabolic interaction. This article systematically elaborates on the association between gut microbiota and COPD: First, it deeply analyzes the pathological interaction between the gut and lungs from the perspective of the gut-lung axis. On this basis, it examines the characteristic changes in gut microbiota and their metabolites in COPD patients, explores the key influencing factors driving such microbiota dysbiosis, and further systematically explains the core mechanisms by which gut microbiota contribute to the occurrence and progression of COPD. Finally, it focuses on strategies for the prevention and treatment of COPD based on gut microbiota regulation, and prospects their clinical application potential. The purpose of this article is to provide new ideas and directions for the basic research and clinical practice of COPD by comprehensively sorting out the association between gut microbiota and COPD, thereby helping to improve the current status of COPD prevention and treatment.\n\nID: 41994273\nTitle: Targeting the gut-lung axis in COPD: from microbial metabolites to fecal microbiota transplantation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is a complex, multidimensional syndrome manifested by persistent airway inflammation, oxidative stress, and progressive airflow limitation, with pathology extending far beyond the lung. The gut-lung axis has emerged as a pivotal paradigm for understanding this systemic nature, underscoring the regulatory potency of gut microbiota-derived metabolites in inter-organ immune and metabolic crosstalk. Accumulating evidence suggests that COPD is intricately linked to gut microbiota dysbiosis and widespread disturbances in bioactive metabolites, particularly short-chain fatty acids (SCFAs), tryptophan-related amino acids (AAs), and bile acids (BAs). These metabolic aberrations exacerbate pulmonary inflammation by dysregulating immune homeostasis, compromising intestinal barrier integrity, and skewing redox balance. Fecal microbiota transplantation (FMT), as a strategy capable of comprehensively reconstituting gut microbial and metabolic homeostasis, has demonstrated potential in preclinical and translational settings to attenuate pulmonary injury via the gut-lung axis. This review centers on gut microbiota-associated metabolites, systematically summarizing their roles in COPD pathogenesis and critically evaluating the emerging evidence and mechanistic basis by which FMT recalibrates COPD progression through metabolic pathways, thereby providing a robust theoretical framework for developing precision gut microbiota-targeted systemic therapeutic strategies.\n\nID: 41994269\nTitle: Electroacupuncture modulates gut-lung microbiota and lung EMT to attenuate airway remodeling in COPD.\nAbstract: Chronic obstructive pulmonary disease (COPD) airway remodeling is primarily driven by epithelial-mesenchymal transition (EMT), which is exacerbated by gut-lung axis (the bidirectional communication between gut and lung microbiota) dysbiosis and systemic inflammation. Although electroacupuncture (EA) demonstrates therapeutic potential in COPD, its mechanisms in modulating the gut-lung axis to alleviate inflammation and EMT remain unclear. In cigarette smoke and lipopolysaccharide (LPS)-induced COPD rats, we evaluated lung function, airway collagen deposition, pro-inflammatory and anti-inflammatory cytokines in serum, bronchoalveolar lavage fluid (BALF), and colon tissue, EMT markers in lung tissue, serum LPS levels, and 16S rRNA sequencing of lung and gut microbiota. Interventions comprised authentic EA at bilateral \"Feishu\" (BL13) and \"Zusanli\" (ST36) acupoints versus sham acupuncture at non-acupoint. Electroacupuncture significantly attenuated airway remodeling, as evidenced by improved lung function and reduced collagen deposition. EA modulated gut-lung microbiota by suppressing pro-inflammatory pathogens and enriching immunoregulatory taxa. These changes correlated with reduced serum endotoxemia and inflammation, marked by decreased pro-inflammatory cytokines and increased IL-10 in serum, BALF, and colon tissues. The ameliorated inflammatory environment was further linked to inhibition of EMT in airways, shown by upregulated epithelial markers and downregulated mesenchymal markers. Correlative analyses supported these associations. Ligilactobacillus enrichment negatively correlated with serum LPS, while Mycoplasmopsis positively associated with inflammation and EMT markers. Sham acupuncture failed to achieve these effects. Electroacupuncture ameliorates airway remodeling in COPD by modulating gut and lung microbiotareducing inflammation and inhibits EMT, suggesting microbiota regulation as a potential contributor to its therapeutic effects.\n\nID: 41988476\nTitle: Finger millet and soybean as functional ingredients in next-generation fermented foods: a review of nutritional, technological, and health-promoting perspectives.\nAbstract: The ever-increasing global malnutrition, environmental degradation, and food insecurity challenges have intensified interest in sustainable food systems and underutilized crops. Fermentation improves the nutritional quality, digestibility, shelf life, and sensory attributes of plant-based foods. Finger millet (Eleusine coracana) and soybean (Glycine max) are promising for functional food development due to their complementary nutrient profiles. Finger millet is rich in minerals, fibre, and polyphenols, while soybean provides high-quality protein and bioactive compounds. Their synergistic amino acid profiles and the benefits of fermentation-such as improved micronutrient bioavailability and reduced antinutritional factors-make them suitable for developing innovative fermented foods. Therefore, this review evaluates the nutritional value, fermentation potential, and health-promoting properties of finger millet and soybean for sustainable nutrition and food security. A narrative review following PRISMA principles was conducted using Google Scholar, PubMed, ScienceDirect, and Scopus. Literature from 2000-2025 on finger millet, soybean, fermentation, and functional foods was searched, yielding 116 records. After screening, 59 peer-reviewed studies were included. Two reviewers independently extracted and analysed data through thematic synthesis on nutritional composition, fermentation methods, microbial ecology, functional properties, and health benefits. The literature shows that fermentation significantly enhances the nutritional and functional value of both crops. Fermentation reduces antinutritional factors such as phytates and tannins, improves protein digestibility, and increases mineral bioavailability. Lactic and acetic acid fermentation also enhance flavour, texture, and shelf stability. However, the review identified a major research gap: few documented fermented foods combine finger millet and soybean despite their complementary nutritional profiles. Finger millet and soybean present strong potential for developing next generation fermented functional foods that address malnutrition, lactose intolerance, and dietary protein deficiencies. Nevertheless, several challenges remain, including fermentation standardization, sensory acceptance, limited infrastructure, and insufficient characterization of microbial communities and bioactive metabolites. Advancing multi-omics research, improving fermentation technologies, and promoting supportive policies and value chains will be critical for translating these crops into scalable, sustainable food innovations.\n\nID: 41983252\nTitle: Exploring the dairy milk matrix beyond isolated nutrients-a narrative review.\nAbstract: The concept of the food matrix considers individual components along with how they are structured, interact, and are modified during processing. There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as milk may have fewer adverse effects associated with high-dose supplemental intake. Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation. Structural and functional manipulation of milk proteins, such as whey and lactoferrin, can also modify matrix functionality; for example, appropriate processing conditions can preserve lactoferrin's iron-binding capacity, supporting iron transport and bioavailability. Compared with plant-based milks, which often require fortification and extensive processing, the dairy milk matrix is particularly effective at promoting nutrient absorption. Our findings highlight the importance of adopting a whole food perspective when considering milk in dietary recommendations and research.\n\nID: 41980958\nTitle: A colon mimetic screening approach reveals Lactobacillus fermentum as a microbiome-based therapy for COPD.\nAbstract: Chronic obstructive pulmonary disease (COPD) remains a major health burden with few effective therapies, particularly for emphysema. The gut-lung axis and microbial metabolites, such as short-chain fatty acids (SCFAs), have emerged as modulators of lung inflammation. We investigated the therapeutic effects of Lactobacillus fermentum HEM20792 (LF), identified through a colon mimetic personalized pharmaceutical meta-analytical screening (PMAS) platform using fecal samples from severe COPD patients. LF and Lactobacillus sakei HEM20224 (LS) were orally administered to smoke-exposed mice, followed by lung function testing, histopathology, RNA sequencing, single-cell transcriptomics, and fecal microbiome/SCFAs analyses. LF attenuated emphysematous changes, improved compliance, and reduced macrophage and IL-17+ lymphocyte infiltration. Single-cell analysis showed restoration of alveolar macrophages and reduction of pathogenic C1q+ macrophages, while transcriptomics revealed normalization of NF-\u03baB and arachidonic acid pathways and attenuation of IL-17- and SPP1-associated signaling. LF also increased fecal SCFAs levels. These findings provide preclinical evidence for LF as a promising microbiome-based therapeutic candidate for COPD.\n\nID: 41965517\nTitle: Intestinal dysbiosis associates with silica-induced pulmonary fibrosis in mice via arginine and tryptophan pathways.\nAbstract: Pulmonary fibrosis (PF) is a life-threatening interstitial lung disease with a lack of effective therapeutic approaches. Silicosis is a subtype of PF that is specifically caused by the inhalation of crystalline silica particles. In recent years, the gut-lung axis has been shown to be involved in the occurrence and progression of various respiratory diseases. However, the involvement and specific mechanism of action of the gut microbiome in silica-induced PF remain to be elucidated. Therefore, we established a silica-induced PF murine model using an inhalation exposure system, and combined gut metagenomic and untargeted metabolomics data to correlate microbial and metabolic changes with profibrotic cytokine levels. In mice exposed to silica dust for 64 days and 128 days, Akkermansia muciniphila and Staphylococcus lentus were significantly enriched, whereas the abundance of Lactobacillus murinus was notably reduced. Relevant network analysis revealed that these gut microbiota changes were highly correlated with metabolic disorders of tryptophan and arginine. Moreover, changes in the gut microbiome composition corresponded with the fluctuations in the levels of profibrotic cytokines, including transforming growth factor-beta, tumor necrosis factor-alpha, fibroblast growth factor, and hydroxyproline. We successfully established a murine model of PF induced by silica inhalation. Our results suggest that Lactobacillus murinus, Akkermansia muciniphila, and Staphylococcus lentus are key microorganisms involved in the development of silica-induced PF, while the arginine and tryptophan metabolic pathways serve as key regulatory pathways in the gut-lung axis contributing to disease development.\n\nID: 41910951\nTitle: Metagenomics in Obstructive Lung Diseases: Insights into Microbial Dysbiosis, Host-Microbe Interactions, and the Gut-Lung Axis.\nAbstract: Obstructive lung diseases (OLDs), including asthma and chronic obstructive pulmonary disease (COPD), arise from complex interactions among microbial ecosystems, host immunity, metabolic regulation, and environmental exposures. Metagenomic approaches have substantially advanced understanding of these interactions by enabling comprehensive profiling of respiratory and gut-associated microbiomes and their functional potential. Evidence indicates that asthma is frequently associated with early-life microbial perturbations, reduced community diversity, enrichment of Streptococcus, Moraxella, and allergen-associated fungi, and gut dysbiosis that influences immune maturation and tolerance. In contrast, COPD is characterized by adult-onset dysbiosis with Proteobacteria dominance, depletion of commensal anaerobes such as Prevotella and Veillonella, and functional signatures linked to chronic inflammation, xenobiotic metabolism, and exacerbation risk. Across both diseases, alterations in gut microbial composition and metabolite profiles, including short-chain fatty acids, highlight the gut-lung axis as a key regulatory interface shaping airway immune responses. Despite these advances, critical knowledge gaps remain, including limited longitudinal data, incomplete multi-kingdom analyses, and insufficient mechanistic and translational validation of disease-associated microbiome signatures. This review integrates current metagenomic evidence to delineate disease-specific and shared microbial patterns, examines host-microbe interaction pathways within molecular and clinical contexts, and critically evaluates the implications and limitations of microbiome-based interventions. By framing microbiome research within a systems biology and public health perspective, this article underscores the importance of context-dependent interpretation and identifies priorities for future longitudinal, mechanistic, and translational studies in OLDs.\n\nID: 41904863\nTitle: Germination-tunable structural remodeling of LAB-fermented soymilk gels: Unraveling gastrointestinal digestive fate and bioactive peptide release.\nAbstract: This study explores how germination duration affects the structure and gastrointestinal digestion of LAB-fermented soymilk gels. Soybeans germinated for 0-3\u00a0days were fermented, with their rheology, microstructure, intermolecular interactions, and in vitro digestion analyzed. Germination weakened gel viscoelasticity, increased pore size, and shifted the dominant forces from hydrogen bonds to hydrophobic interactions. This is likely due to the higher endogenous proteases and 7S/11S ratio. Germination-derived gels (especially 2-3\u00a0days) disintegrated faster in the stomach, released more soluble protein in the intestine, and produced more peptides. Peptidomic analysis revealed that 2-day germination (fermented soft gel, FSG) yielded the most bioactive peptides via targeted subunit degradation, while 3-day germination (fermented ultrasoft gel, FUG) caused over-hydrolysis, leading to loss of specific bioactive motifs. These findings demonstrate that controlled germination time (2-day) optimizes LAB-fermented gel structure to improve digestive efficiency and bioactive peptide release, providing a novel strategy for designing plant-based dairy.\n\nID: 41895991\nTitle: Effect of processing on the protein digestibility and mineral bioavailability of legumes.\nAbstract: This study evaluates how processing methods, soaking/cooking, fermentation (e.g. tempeh), and protein coagulation (e.g. tofu), affect the nutritional profile, protein digestibility, and mineral bioavailability of faba beans, grey peas, yellow peas, and soybeans. Protein digestibility was assessed using in vitro digestion and o-phthalaldehyde (OPA) assay, whilst mineral bioavailability was estimated using phytate-to-mineral molar ratios and further evaluated using a Caco-2/HT29-MTX co-culture model measuring ferritin formation. Processing markedly influenced nutritional properties. Protein coagulation resulted in the highest protein content and degree of hydrolysis, indicating improved protein digestibility. Fermentation substantially reduced phytate levels across all crops, in some cases below detection limits, leading to lower phytate-to-mineral ratios compared with cooked and tofu products. Consistent with these estimates, higher ferritin formation was observed in cells exposed to digested fermented products than to tofu digesta. Processing also altered amino acid composition, reflecting structural modifications of proteins. Overall, the results demonstrate that processing modulates protein digestibility and mineral bioavailability of legumes. Fermentation shows potential to enhance mineral availability, whereas protein coagulation improves protein digestibility. These findings are based on in vitro and cell-based models and provide guidance for the development of nutritionally improved plant-based foods.\n\nID: 41895350\nTitle: Understanding gut microbiota dysbiosis as a plausible link between obstructive sleep apnea (OSA), viral infections, and lifestyle diseases.\nAbstract: Obstructive sleep apnea (OSA) is a multifactorial disorder which is influenced by intermittent hypoxia, sleep fragmentation, and systemic inflammation. Recent evidence suggests that lifestyle diseases and viral infections further exacerbate OSA severity through common inflammatory and metabolic pathways. Parallelly, gut dysbiosis has gained recognition as a key mediator which links respiratory, metabolic, and infectious disease processes via the gut-lung axis. This review explores the convergent role of gut microbial dysbiosis across OSA, lifestyle-associated comorbidities such as obesity, diabetes, and cardiovascular disease and viral infections including respiratory syncytial virus (RSV), influenza, dengue, Human Immunodeficiency Virus (HIV), and SARS-CoV-2. Across these conditions, a recurring pattern of reduced beneficial commensals (e.g., Bifidobacterium, Faecalibacterium prausnitzii, Roseburia, Akkermansia muciniphila) and a noted increase of pro-inflammatory taxa (e.g., Escherichia, Streptococcus, Enterobacteriaceae) has been observed. It contributes to epithelial barrier breakdown, endotoxemia, metabolic dysfunction, and immune dysregulation. In OSA patients, intermittent hypoxia is observed that causes gut barrier impairment and microbial translocation, thus amplifying systemic inflammation. Similarly, viral infections reshape the gut ecology, bringing adverse effects to host immunity and respiratory outcomes. The review highlights upon the therapeutic potentials of prebiotics and probiotics supplementation for modulating gut dysbiosis. It discusses the role of these therapeutic interventions in improving metabolic homeostasis, reducing inflammation, and potentially mitigating OSA-related complications. Collectively, this analysis highlights gut dysbiosis as a plausible unifying mechanism connecting lifestyle diseases, viral infections, and OSA, presenting a compelling avenue for integrated, microbiome-targeted interventions.\n\nID: 41878303\nTitle: Gut-Lung Axis in COPD: Investigating the Impact of Dietary Fiber Intake on Systemic Inflammation and Lung Function Decline.\nAbstract: The gut-lung axis represents a promising therapeutic target in chronic obstructive pulmonary disease (COPD). This study investigated whether dietary fiber intake differs between COPD patients and healthy controls, and examined its association with systemic inflammation and lung function. A case-control study was conducted including 100 COPD patients (cases) and 100 age- and sex-matched healthy controls. Dietary fiber intake was assessed using a validated food frequency questionnaire. Systemic inflammatory markers (CRP, IL-6) were measured by ELISA. Lung function parameters (FEV1, FEV1/FVC, DLCO) were evaluated according to ATS/ERS guidelines. Logistic regression analysis was performed to assess the association between dietary fiber intake and COPD risk. COPD patients had significantly lower dietary fiber intake (18.30 \u00b1 6.20 g/day) compared to controls (28.70 \u00b1 8.10 g/day, P < 0.001). Inflammatory markers were significantly elevated in COPD patients: CRP (5.80 \u00b1 3.20 vs. 1.20 \u00b1 0.80 mg/L), IL-6 (8.40 \u00b1 4.10 vs. 2.10 \u00b1 1.30 pg/mL) (all P < 0.001). In COPD patients, dietary fiber intake was inversely correlated with CRP (r = -0.52), IL-6 (r = -0.48), and positively correlated with FEV1 (r = 0.41) and DLCO (r = 0.38) (all P < 0.001). After adjusting for confounders, low dietary fiber intake (<20 g/day) was associated with 3.2-fold increased odds of COPD (OR = 3.24, 95% CI: 1.86-5.65, P < 0.001). Low dietary fiber intake is significantly associated with COPD and correlates with increased systemic inflammation and reduced lung function. These findings support the potential role of the gut-lung axis in COPD pathophysiology. However, causality cannot be established due to the limitations of the cross-sectional case-control design. Prospective interventional studies are warranted to confirm these associations and evaluate whether dietary fiber modification can improve clinical outcomes in COPD patients.\n\nID: 41877093\nTitle: The red cell distribution width-to-albumin ratio mediates the association between the dietary index for gut microbiota and chronic obstructive pulmonary disease.\nAbstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major global health burden, with emerging evidence implicating gut microbiota dysbiosis via the gut-lung axis. The Dietary Index for Gut Microbiota (DI-GM) quantifies dietary impact on microbial health, but the mechanisms linking DI-GM to COPD risk remain unclear. This study aimed to investigate whether systemic inflammatory-nutritional biomarkers might explain the association between DI-GM and COPD, with a focus on the red cell distribution width-to-albumin ratio (RAR). METHODS: This cross-sectional analysis included 20,487 U.S. adults aged\u2009\u2265\u200940 years from the National Health and Nutrition Examination Survey (2005\u20132018). DI-GM was derived from 24-hour dietary recalls, and COPD was defined by self-reported physician diagnosis. Survey-weighted multivariable logistic regression and mediation analysis were used to assess associations and statistically decompose the potential mediating effects of 11 inflammatory-nutritional biomarkers. RESULTS: Each one-unit increase in DI-GM was associated with an 8% reduction in COPD prevalence (odds ratio 0.92, 95% confidence interval 0.88\u20130.97). In the mediation analysis, RAR was the most robust factor, accounting for 10.3% of the observed total association. Other biomarkers, including the neutrophil percentage-to-albumin ratio and monocyte-to-albumin ratio, showed significant but weaker contributions. These findings were consistent in sensitivity analyses. CONCLUSIONS: Adherence to a gut microbiota-beneficial diet is associated with reduced COPD risk, and this association may be partially explained by systemic inflammatory-nutritional status. RAR emerged as a significant intermediary factor in this observed association, providing epidemiological clues for the gut-lung axis and suggesting its potential as a biomarker for further investigation in targeted prevention strategies.\n\nID: 41874370\nTitle: Gut microbiota impact on lung diseases: a mini review of clinical evidence.\nAbstract: The gut-lung axis represents a bidirectional communication network through which the gut microbiota (GM) influences respiratory health. This mini-review synthesizes clinical evidence on the role of the GM in lung diseases. We focused exclusively on human clinical trials, randomized controlled trials, meta-analyses, and systematic reviews, sourced from major databases after duplicate removal. The evidence indicates that GM dysbiosis is a significant risk factor for the susceptibility and severity of various respiratory conditions, including asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and infections, such as COVID-19 and pneumonia. Specific microbial signatures and metabolic profiles, particularly involving short-chain fatty acids (SCFAs), are associated with disease states and outcomes. Interventions like probiotics, prebiotics, synbiotics, and fecal microbiota transplantation (FMT) show promise in modulating the GM and improving clinical parameters, though their efficacy can be inconsistent and influenced by confounding factors. In conclusion, the GM is a promising therapeutic target for lung diseases. However, future research must prioritize large-scale, longitudinal clinical trials and deeper mechanistic investigations to establish causality and develop effective, personalized microbiome-based therapies.\n\nID: 41852666\nTitle: Microencapsulated Akkermansia muciniphila alleviates acute lung injury in juvenile mice by protecting intestinal barrier.\nAbstract: The gut-lung axis plays a critical role in the pathogenesis of acute lung injury (ALI). While intestinal microbiota, particularly Akkermansia muciniphila (AKK), has been linked to the regulation of ALI in adult murine model, its impact on juvenile hosts, who exhibit heightened susceptibility to lipopolysaccharide (LPS)-induced ALI, remains poorly understood. Moreover, despite microencapsulation enhancing the probiotic gastrointestinal survival and colonization of probiotics, the therapeutic potential of microencapsulated AKK (AKK-MC) in juvenile murine ALI has not been explored. In this study, juvenile mice were orally gavaged with live AKK or AKK-MC for 14 days, with LPS-induced ALI established on day 11. Lung tissues were analyzed for morphological changes and inflammatory cytokine analysis. Bronchoalveolar lavage fluid (BALF) was collected for total cell counts and protein concentration. Macrophages and neutrophils infiltration in the lungs was quantified via immunofluorescence staining. Four segments of the intestinal tract (jejunum, ileum, cecum, and colon) were harvested for histological analysis using hematoxylin and eosin (H&E), Alcian blue-periodic acid-Schiff (AB-PAS), and toluidine blue (TBO) staining. These evaluations included measurements of villus height to crypt depth, intestinal injury scoring, and counts of goblet and mast cells. AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage. This was evidenced by reduced protein concentration and cell counts in BALF, downregulation of Tnf-\u03b1 and Il-1\u03b2 expression, improved lung histology, and decreased macrophage infiltration and neutrophil extracellular traps formation. In the intestine, AKK treatment restored mucosal architecture, increased villus height to crypt depth ratios, maintained goblet cell populations, and reduced mast cell infiltration across intestinal segments. These results demonstrate that microencapsulation enhances AKK's efficacy in ameliorating LPS-induced ALI in juvenile mice through gut microbiota modulation. This study provides a crucial foundation for the development of probiotic-based interventions in pediatric ALI.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

However, low bioavailability and unclarified therapeutic mechanisms impeded its deeply application. Plant-derived exosome-like nanoparticles offered a promising option for improving bioavailability and targeted delivery capability. To obtain dark tea-derived exosome-like nanovesicles (DTELNs) and clarify their material basis, investigate the therapeutic effects on hepatocyte carcinoma (HCC) and potential mechanisms. DTELNs were isolated by tangential flow filtration, TEM, NTA, nucleic acid & protein analysis system and LC-MS/MS were used to characterize their morphological characteristics and chemical composition. Orthotopic HCC model mice were established and employed for DTELNs' oral administration. Living imaging, H&E staining and biochemical assays were used to evaluate therapeutic effects. Untargeted metabolomic, 16S rRNA sequencing and cytometry by time-of-flight (CyTOF) were used to investigate the alteration of endogenous substances and immune features. Potential targets were explored by network pharmacology, protein-protein interaction, and verified by western blot. Finally, HCC patient-derived organoids were generated to evaluate the clinical applicability of DTELNs. DTELNs exhibited typical exosomal features, major components including flavonoids, phenolic acids, lipids, amino acids and their derivatives, and miRNAs. DTELNs markedly suppressed tumor proliferation, modulated gut microbial diversity, normalized liver-gut axis physiological homeostasis and enhanced immune responses. DTELNs distinctly downregulated the expressions of p-Akt, NF-\u03baB, Bcl-2, cyclin D1, upregulated the expressions of p-p53, PTEN, Bax, cleaved-caspase 3 and p21. DTELNs also exhibited potent inhibitory effect on HCC organoids. DTELNs demonstrated potent therapeutic efficacy against HCC. The mechanisms mainly involved directly modulating Akt-related signalling pathways, rebalancing gut microbiota and related metabolites, and further boosting anti-tumor immune responses.\n  --- END ACTUAL ABSTRACT FOR 42424676 ---\n\n- ERROR: You cited ID: 42297164 for the quote: \"Their therapeutic significance of seaweed polysaccharides lies in their microbiota-mediated, multi-organ actions rather than in isolated biological effects.\"\n  FACT: Strict Misquote Detected!

Resistant to upper gastrointestinal digestion, they reach the colon where gut microbiota ferment them into metabolites, chiefly short-chain fatty acids (SCFAs). These metabolites in turn modulate intestinal barrier integrity, immune and metabolic homeostasis, and inter-organ signaling. However, a critical caveat is that each polysaccharide type exhibits substantial structural variability in molecular weight, degree and position of sulfation, monosaccharide composition, and linkage pattern, depending on species, harvest time, and extraction method. This variability fundamentally alters fermentation kinetics and SCFA profiles, yet most studies treat these polysaccharides as uniform entities. This review critically synthesizes current in vitro and in vivo evidence and emphasizes that the therapeutic significance of seaweed polysaccharides lies in their microbiota-mediated, multi-organ actions rather than in isolated biological effects. In addition, we analyzed the main challenges for food and health applications, including variability in polysaccharide sources and extraction methods, limited bioavailability, pollution risk, and the lack of coordinated global regulations. Addressing these gaps is essential for translating promising biological activities into safe, standardized functional components and for developing these polysaccharides into functional ingredients that can modulate the gut-liver-brain axis.\n  --- END ACTUAL ABSTRACT FOR 42297164 ---\n\n- ERROR: You cited ID: 42040562 for the quote: \"Exogenous supplementation with SCFAs (acetic acid and propionic acid) activated the key receptor GPR43, suppressed the expression of NETs marker proteins (NE, MPO, and CitH3) and attenuated inflammatory cytokine levels in COPD rats.\"\n  FACT: Quote was found in context but NOT in the specific abstract mapped to ID '42040562'.\n  \n  Below is the complete, true text of ID 42040562 that you MUST read. \n  Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n  \n  --- BEGIN ACTUAL ABSTRACT FOR 42040562 ---\n  ID: 42040562\nTitle: Global research trends and thematic evolution of respiratory microbiota in COPD: a bibliometric study.\nAbstract: Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a disorder influenced by the respiratory microbiota. Microbial dysbiosis has been linked to disease progression, inflammation, and clinical outcomes. However, a comprehensive overview of the global research landscape and evolving themes in this field is still lacking. Publications on COPD and respiratory microbiota were retrieved from the Web of Science Core Collection (WoSCC) and Scopus databases. Bibliometric analyses, including publication trends, co-authorship networks, keyword co-occurrence, citation bursts, and thematic evolution, were conducted using VOSviewer, CiteSpace, and the bibliometrix package in R. Between 2001 and 2025, 296 publications were identified in WoSCC and 433 in Scopus, reflecting a sustained growth in research output. Keyword co-occurrence and clustering analyses revealed three main research hotspots: (1) respiratory microbiota composition and dynamics, (2) pathogen colonization and inflammation-related processes, and (3) clinically relevant outcomes. Citation burst and thematic evolution analyses demonstrated a clear temporal shift from pathogen-centered studies toward microbiota-based, dynamic, and clinically oriented research paradigms. International collaboration is increasingly prominent, with China, the USA, and the UK leading in productivity and citation impact. This bibliometric study systematically delineates the intellectual structure and evolving trends of COPD-related respiratory microbiota research. Our findings highlight the maturation of the field, reveal emerging research directions such as multi-omics integration and gut-lung axis interactions, and provide a quantitative reference for guiding future translational and microbiota-focused studies in COPD.\n  --- END ACTUAL ABSTRACT FOR 42040562 ---\n\n- ERROR: You cited ID: 41994269 for the quote: \"Electroacupuncture modulates gut-lung microbiota by suppressing pro-inflammatory pathogens and enriching immunoregulatory taxa.\"\n  FACT: Strict Misquote Detected!

Although electroacupuncture (EA) demonstrates therapeutic potential in COPD, its mechanisms in modulating the gut-lung axis to alleviate inflammation and EMT remain unclear. In cigarette smoke and lipopolysaccharide (LPS)-induced COPD rats, we evaluated lung function, airway collagen deposition, pro-inflammatory and anti-inflammatory cytokines in serum, bronchoalveolar lavage fluid (BALF), and colon tissue, EMT markers in lung tissue, serum LPS levels, and 16S rRNA sequencing of lung and gut microbiota. Interventions comprised authentic EA at bilateral \"Feishu\" (BL13) and \"Zusanli\" (ST36) acupoints versus sham acupuncture at non-acupoint. Electroacupuncture significantly attenuated airway remodeling, as evidenced by improved lung function and reduced collagen deposition. EA modulated gut-lung microbiota by suppressing pro-inflammatory pathogens and enriching immunoregulatory taxa. These changes correlated with reduced serum endotoxemia and inflammation, marked by decreased pro-inflammatory cytokines and increased IL-10 in serum, BALF, and colon tissues. The ameliorated inflammatory environment was further linked to inhibition of EMT in airways, shown by upregulated epithelial markers and downregulated mesenchymal markers. Correlative analyses supported these associations. Ligilactobacillus enrichment negatively correlated with serum LPS, while Mycoplasmopsis positively associated with inflammation and EMT markers. Sham acupuncture failed to achieve these effects. Electroacupuncture ameliorates airway remodeling in COPD by modulating gut and lung microbiotareducing inflammation and inhibits EMT, suggesting microbiota regulation as a potential contributor to its therapeutic effects.\n  --- END ACTUAL ABSTRACT FOR 41994269 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects.\" (Source: 42556887)\n- \"This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations.\" (Source: 42514077)\n- \"Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy\" (Source: 42509759)\n- \"We examine how fermentation technologies transform herbal byproducts into high-value anti-obesity preparations through biological processes that enhance bioactive compounds, improve bioavailability, and modulate the gut-liver axis.\" (Source: 42415755)\n- \"Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites.\" (Source: 42337354)\n- \"Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology.\" (Source: 42324006)\n- \"Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses.\" (Source: 42316508)\n- \"While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects.\" (Source: 42293527)\n- \"Probiotic supplementation significantly improved FEV1 and FVC within the intervention group, although between-group spirometric differences were not significant.\" (Source: 42286603)\n- \"We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders.\" (Source: 42244886)\n- \"PGP reduced xanthine oxidase activity, modulated purine metabolism, and increased beneficial gut bacteria (Akkermansia muciniphila) and short-chain fatty acids (acetate, butyrate, propionate).\" (Source: 42237852)\n- \"Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins.\" (Source: 42169007)\n- \"Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation.\" (Source: 42022800)\n- \"Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation.\" (Source: 41983252)\n- \"AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group.

However, while *Akkermansia muciniphila* is widely documented to thrive on mucin glycans, the specific claim regarding its possession of \u03b2-N-acetylhexosaminidases as the unique colonization mechanism is not explicitly detailed within the provided literature; the text confirms its reliance on mucin glycans but lacks specific enzyme mapping.

Botanical matrices, when processed through fermentation, overcome limitations of poor bioavailability. \"Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects.\" The utilization of these food-based matrices acts as a delivery system, where \"Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites.\" *Akkermansia muciniphila* is central to this paradigm, as \"AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage.\" Further, the therapeutic impact of such interventions is often dependent on the matrix, as \"Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses.\" \n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Fermentation enables the transformation of plant-derived phytochemicals into more bioavailable forms, such as aglycones, which are essential for systemic therapeutic efficacy.\n*   *Akkermansia muciniphila* plays a dual role in hyperuricemia and COPD, serving as both a biomarker of health and a therapeutic agent that supports barrier integrity.\n*   Colloidal delivery systems for bioactive compounds, such as curcumin, significantly influence their spatiotemporal accumulation in the gut and subsequent microbial modulation.\n*   The \"gut-lung axis\" is not merely an immunological pathway; it is a metabolic rheostat fueled by short-chain fatty acids (SCFAs) and tryptophan metabolites.\n*   Heat-inactivated *Akkermansia muciniphila* (postbiotics) exhibits therapeutic potential comparable to live bacteria in modulating uric acid metabolism and inflammatory pathways.\n*   Cisplatin-induced nephrotoxicity represents another systemic disease context where gut-kidney axis modulation via polysaccharides mimics gut-lung axis dynamics.\n*   The use of probiotics, such as *Lactobacillus* species, provides an adjunctive therapy to reduce emphysema and inflammation in COPD by restoring microbial diversity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, the underlying mechanisms by which the gut commensal species enhance antitumor immunity remain largely unexplored. Here, we show that the gut microbiota from healthy individuals conferred considerable sensitivity to anti-PD-1 in the colorectal cancer (CRC) tumor-bearing mice, whereas gut microbiota from CRC patients failed to do so. By 16S rRNA gene sequencing, we identified Lactobacillus that was significantly increased in the mice with good response to anti-PD-1, and significantly correlated with anti-tumor immunity. After a series of screening, we isolated a novel Lacticaseibacillus strain, named L. paracasei sh2020. L. paracasei sh2020 showed the most notable anti-tumor immunity in the mice with gut dysbiosis. Mechanistically, the antitumor immune response elicited by L. paracasei sh2020 was dependent on CD8+ T cell. In vitro and in vivo studies revealed that L. paracasei sh2020 stimulation triggered the upregulated expression of CXCL10 in the tumors and subsequently enhanced CD8+ T cell recruitment. Meanwhile, the modulation of gut microbiota caused by L. paracasei sh2020 enhanced its antitumor effect and gut barrier function. Overall, our study offered novel insights into the mechanism by which gut microbiota shaped the outcome of cancer immunotherapy and, more importantly, the novel strain L. paracasei sh2020 might serve as an easy and effective way to promote anti-PD-1 effect in clinical practice.",
        "35265071": "ID: 35265071\nTitle: The Ability of Resveratrol to Attenuate Ovalbumin-Mediated Allergic Asthma Is Associated With Changes in Microbiota Involving the Gut-Lung Axis, Enhanced Barrier Function and Decreased Inflammation in the Lungs.\nAbstract: Asthma is a chronic respiratory disease highly prevalent worldwide. Recent studies have suggested a role for microbiome-associated gut-lung axis in asthma development. In the current study, we investigated if Resveratrol (RES), a plant-based polyphenol, can attenuate ovalbumin (OVA)-induced murine allergic asthma, and if so, the role of microbiome in the gut-lung axis in this process. We found that RES attenuated allergic asthma with significant improvements in pulmonary functions in OVA-exposed mice when tested using plethysmography for frequency (F), mean volume (MV), specific airway resistance (sRaw), and delay time(dT). RES treatment also suppressed inflammatory cytokines in the lungs. RES modulated lung microbiota and caused an abundance of Akkermansia muciniphila accompanied by a reduction of LPS biosynthesis in OVA-treated mice. Furthermore, RES also altered gut microbiota and induced enrichment of Bacteroides acidifaciens significantly in the colon accompanied by an increase in butyric acid concentration in the colonic contents from OVA-treated mice. Additionally, RES caused significant increases in tight junction proteins and decreased mucin (Muc5ac) in the pulmonary epithelium of OVA-treated mice. Our results demonstrated that RES may attenuate asthma by inducing beneficial microbiota in the gut-lung axis and through the promotion of normal barrier functions of the lung.",
        "35274663": "ID: 35274663\nTitle: Novel anti-hyperuricemic hexapeptides derived from Apostichopus japonicus hydrolysate and their modulation effects on the gut microbiota and host microRNA profile.\nAbstract: Hyperuricemia (HUA) is the second most common metabolic disease nowadays, and is characterized by permanently increased concentrations of serum uric acid. In this study, two novel hexapeptides (GPAGPR and GPSGRP) were identified from Apostichopus japonicus hydrolysate and predicted to have xanthine oxidase (XOD) inhibitory activity by molecular docking. Their in vitro XOD inhibition rates reached 37.3% and 48.6%, respectively, at a concentration of 40 mg mL-1. Subsequently, in vivo experiments were carried out in a HUA mouse model, and we found that both peptides reduced the serum uric acid by inhibiting uric acid biosynthesis and reabsorption, as well as alleviated renal inflammation via suppressing the activation of the NLRP3 inflammasome. 16S rDNA sequencing indicated that both peptide treatments reduced the richness and diversity of the gut microbiota, altered the composition in the phylum and genus levels, but different change trends were observed in the phylum Verrucomicrobia and genera Akkermansia, Dubosiella, Alloprevotella, Clostridium unclassified and Alistipes. In addition, changes in the renal microRNA (miRNA) profiles induced by GPSGRP treatment were analyzed; 21 differentially expressed (DE) miRNAs were identified among groups, and KEGG pathway analysis indicated that their potential target genes were involved in pluripotency of stem cell regulation, mTOR signaling pathway and proteoglycans. Moreover, ten miRNAs involved in the HUA onset and alleviation were identified, which showed a high correlation with genera related to the metabolism of short-chain fatty acids, bile acids and tryptophan. This study delineated two hexapeptides as potential microbiota modulators and miRNA regulators that can ameliorate HUA.",

(Asteraceae), Achyranthes bidentata Blume (Amaranthaceae) and Coix lacryma-jobi var. ma-yuen (Rom.Caill.) Stapf (Poaceae), and used to treat gouty arthritis and hyperuricemia for thousands of years. However, the mechanisms underlying its beneficial efficacy on diabetes still needs to be explored. Our study was performed to reveal the effects of the 75% ethanol extraction of Simiao Wan (SMW) on diabetes, gut microbiota and bile acids (BAs) in diabetic mice. The effects of SMW on diabetes were evaluated in mice treated by high-fat diet (HFD)/streptozotocin (STZ). The 16S rDNA sequencing and BAs metabolomics were performed to assess the changes of BAs profiles and gut microbiota induced by SMW. Western blot and real-time quantitative PCR were conducted to evaluate the possible mechanism of SMW. SMW significantly improved insulin resistance and hepatic lipid accumulation in HFD/STZ mice. It remarkably enriched in the bacteria Allobaculum, Clostridium, Akkermansia, Lactobacilus and Bilophila whereas decreased Coprococcus and Halomonas in diabetic mice. Furthermore, the profiles of BAs were also modulated by SMW, indicated by the reduction of conjugated BAs and 12\u03b1-OH/non-12\u03b1-OH BAs ratio in liver as well as the increase of primary BAs in feces. SMW also activated farnesoid X receptor and inhibited sterol regulatory element-binding protein-1 expression, contributing to its beneficial actions on lipid accumulation in liver. Our results showed that SMW exerted its beneficial effects on insulin resistance and hepatic lipid accumulation indirectly through regulating profiles of gut microbe and BAs.",

Previous studies have associated antimicrobial use with allergies, but the real impact of antibiotics on asthma is still elusive. We investigated the potential impact of amoxicillin (Amox), trimethoprim/sulfamethoxazole (TMP/SMX), and metronidazole (Metro) in a murine model of OVA-induced allergic airway inflammation. BALB/c mice received three cycles of 7 days of antibiotics in drinking water followed by 7 days washout and were sensitized i.p. with OVA/Alum at days 0 and 14. After the end of the last antibiotic washout, the mice were challenged with aerosolized OVA. Pulmonary parameters were evaluated, and serum, BAL, and feces were collected for analysis. Amox- and TMP/SMX-treated animals displayed more severe allergic airway inflammation parameters with increased airway hyperresponsiveness, reduced lung alveolar volume, and increased levels in BAL of IL-4 and IL-6. In contrast, Metro-treated mice showed preserved FEV-50, decreased lung inflammation, and higher levels of butyrate and propionate in their feces. Metro treatment was associated with increased OVA-specific IgA in serum. BAL microbiota was abundant in allergic groups but not in nonallergic controls with the Amox-treated group displaying the increased frequency of Proteobacteria, while Metro and TMP/SMX showed increased levels of Firmicutes. In the gut, we observed the enrichment of Akkermansia muciniphila associated with reduced airway inflammation phenotype in the Metro group, even after the recovery period. Our data suggest that different antibiotic treatments may impact the course of experimental allergic airway inflammation in diverse ways by several mechanisms, including modulation of short-chain fat acids production by intestinal microbiota.",

Sprague Dawley rats were given PM2.5 suspension at a dose of 20 mg/l twice a week for 8 weeks. Then, 100 mg/kg or 200 mg/kg of AAP was administered to the rats after PM2.5 exposure. The bronchoalveolar lavage fluid (BALF) and lung tissue samples were collected at the end of the experiment. The BALF was meant to detect changes in lung microbiome by 16S sequences and cluster analysis, with the application of the principal component analysis and the partial least squares discriminant analysis. The levels of interferon-\u03b3 (IFN-\u03b3), and interleukin (IL)-4, IL-8, and IL-10 in lung tissue were detected by the enzyme-linked immunosorbent assay method. The pathological changes in lung tissue were observed by hematoxylin and eosin staining. After PM2.5 exposure, the alveolar septum was widened, and the structures of alveolar walls were destroyed. There was inflammatory cells infiltration in the alveolar space and the interstitial space. Alpha diversity in BALF showed that the Chao1, ACE, Simpson, and Shannon values were increased, and the lung microbiome analysis revealed that the relative abundance of Firmicutes and Clostridium increased, while the relative abundance of Bacteroidetes and Akkermansia decreased. The contents of IFN-\u03b3 and IL-8 in lung tissue increased while the content of IL-10 decreased. After the administration of AAP, the alveolar structure damage was alleviated, and the interstitial hemorrhage, edema, and inflammatory cells infiltration were reduced. The Chao1 and ACE values decreased, and the taxonomic abundance values of Akkermansia were much higher. Simultaneously, the contents of IFN-\u03b3, IL-4, and IL-8 decreased, and the content of IL-10 increased. It was found that PM2.5 resulted in lung microbiome disorder, which might lead to the inflammation of lung tissue. It was also revealed that AAP could alleviate the inflammatory damage of lung tissue induced by PM2.5. Int J Occup Med Environ Health. 2022;35(6):651-64.",

The gut microbiota could be one of the many factors underlying this phenomenon. We aimed to assess the difference in taxonomic and predicted functional profiles of the gut microbiota between asymptomatic hyperuricemia (AH) individuals and gout patients. The V3-V4 region of the 16S rRNA gene of the gut microbiota of AH individuals, gout patients, and controls was sequenced. Bioinformatic analyses were carried out with QIIME2 and phyloseq to determine the difference in the relative abundance of bacterial genera among the study groups. Tax4fun2 was used to predict the functional profile of the gut microbiota. AH individuals presented a higher abundance of butyrate- and propionate-producing bacteria than gout patients; however, the latter had more bacteria capable of producing acetate. The abundance of Prevotella genus bacteria was not significantly different between the patients but was higher than that in controls. This result was corroborated by the functional profile, in which AH individuals had less pyruvate oxidase abundance than gout patients and less abundance of an enzyme that regulates glutamate synthetase activation than controls. We observed a distinctive taxonomic profile in AH individuals characterized by a higher abundance of short-chain fatty acid-producing bacteria in comparison to those observed in gout patients. Furthermore, we provide scientific evidence that indicates that the gut microbiota of AH individuals could provide anti-inflammatory mediators, which prevent the appearance of gout flares. Key Points \u2022 AH and gout patients both have a higher abundance of Prevotella genus bacteria than controls. \u2022 AH individuals' gut microbiota had more butyrate- and propionate-producing bacteria than gout patients. \u2022 The gut microbiome of AH individuals provides anti-inflammatory mediators that could prevent gout flares.",

However, how BBR modulates the microbiota to slow HUA progression is unclear. In this study, we showed that BBR alleviated potassium oxonate (PO)-induced HUA in mice by suppressing the expression of xanthine oxidase (XOD) in the liver and urate transporter 1 (URAT1) and glucose transporter 9 (GLUT9) in the kidney. The BBR also improved renal inflammation by inhibiting the expression of TNF-[Formula: see text], IL-1[Formula: see text], and caspase-1. Subsequently, we evaluated whether the observed anti-HUA effects of BBR were associated with changes in gut microbial structure in mice. 16S rRNA sequencing data showed that BBR significantly altered the community compositional structure of the gut microbiota. Specifically, BBR enriched the abundance of Coprococcus, Bacteroides, Akkermansia, and Prevotella. Antibiotic treatment can reverse the anti-HUA effects of BBR that further supports the role of the gut microbiota. In conclusion, our study provides evidence that BBR ameliorates PO-induced HUA by modulating the gut microbiota.",

In this study, live and pasteurized A. muciniphila were examined for their efficacy in alleviating hyperuricemia in mice. Live and pasteurized A. muciniphila (approximately 2 \u00d7 108 CFU) were given to a hyperuricemic mice model via oral gavage for three weeks. Both forms of A. muciniphila decreased serum urate and inhibited xanthine oxidase in the liver. In addition, fecal and urinal urate was increased in both treatment groups, which corresponds to the changes in the mRNA and protein expression levels of renal uric acid-related transporters (URAT1, GLUT9, and ABCG2) and intestinal ABCG2. Both forms of bacteria reduced the mRNA expression of inflammatory factors in the liver, kidneys and colon. Live A. muciniphila enhanced the expression of tight junction proteins and improved the dysbiosis of intestinal flora. These findings suggest that both live or pasteurized A. muciniphila could effectively attenuate hyperuricemia by moderating uric acid metabolism and inflammation, and live bacteria exhibit additional beneficial effects on the gut microbiota. These findings highlight that A. muciniphila could be potentially developed as a probiotic or postbiotic to combat hyperuricemia.",

The DSS-induced mice were fed a standard rodent chow supplemented with or without TP (8%) for 37 days. The results indicated that the pathological phenotype, gut barrier disruption, and colon inflammation of DSS-induced mice were significantly improved through supplementation of TP. In addition, 16S rRNA-based microbiota or targeted metabolomics analysis indicated that TP ameliorated intestinal microbiota dysbiosis caused by DSS and particularly enhanced the abundances of probiotics correlated with tryptophan metabolism, such as Lactobacillus and Bifidobacterium, where the cecal tryptophan was metabolized to indole-3-propionic acid and indole-3-acetic acid. Consumption of TP markedly enhanced the expression levels of colonic aromatic hydrocarbon receptors and further increased the expressions of intestinal tight junction proteins and interleukin-22 in the colitis mice. Collectively, these findings manifest the protective actions of dietary TP consumption against ulcerative colitis via restoring the intestinal microbiota disorders, promoting microbial metabolism, and improving intestinal barrier damage.",

However, existing studies only provided snapshots of the gut microbiome at single time points, the temporal dynamics of gut microbiota alterations during hyperuricemia progression and the intricate interplay between the gut barrier and microbiota remain underexplored. Our investigation revealed compelling insights into the dynamic changes in both gut microbiota and intestinal barrier function throughout the course of hyperuricemia. The hyperuricemia mice (HY) were given intragastric administration of adenine and potassium oxalate. Gut microbiota was analyzed by 16S rRNA sequencing at 3, 7, 14, and 21 days after the start of the modeling process. Intestinal permeability as well as LPS, TNF-\u03b1, and IL-1\u03b2 levels were measured at 3, 7, 14, and 21 days. We discovered that shifts in microbial community composition occur prior to the onset of hyperuricemia, key bacterial Bacteroidaceae, Bacteroides, and Blautia exhibited reduced levels, potentially fueling microbial dysbiosis as the disease progresses. During the course of hyperuricemia, the dynamic fluctuations in both uric acid levels and intestinal barrier function was accompanied with the depletion of key beneficial bacteria, including Prevotellaceae, Muribaculum, Parabacteroides, Akkermansia, and Bacteroides, and coincided with an increase in pathogenic bacteria such as Oscillibacter and Ruminiclostridium. This microbial community shift likely contributed to elevated lipopolysaccharide (LPS) and pro-inflammatory cytokine levels, ultimately promoting metabolic inflammation. The decline of Burkholderiaceae and Parasutterella was inversely related to uric acid levels, Conversely, key families Ruminococcaceae, Family_XIII, genera Anaeroplasma exhibited positive correlations with uric acid levels. Akkermansiaceae and Bacteroidaceae demonstrating negative correlations, while LPS-containing microbiota such as Desulfovibrio and Enterorhabdus exhibited positive correlations with intestinal permeability. In summary, this study offers a dynamic perspective on the complex interplay between gut microbiota, uric acid levels, and intestinal barrier function during hyperuricemia progression. Our study suggested that Ruminiclostridium, Bacteroides, Akkermansiaceae, Bilophila, Burkholderiaceae and Parasutterella were the key bacteria that play vital rols in the progress of hyperuricemia and compromised intestinal barrier, which provide a potential avenue for therapeutic interventions in hyperuricemia.",

In the present study, we used high-resolution shotgun metagenomics and targeted metabolomic analysis to characterize influenza-associated changes in the composition and metabolism of the mouse gut microbiota. We observed several taxonomic-level changes on day (D)7 post-infection, including a marked reduction in the abundance of members of the Lactobacillaceae and Bifidobacteriaceae families, and an increase in the abundance of Akkermansia muciniphila. On D14, perturbation persisted in some species. Functional scale analysis of metagenomic data revealed transient changes in several metabolic pathways, particularly those leading to the production of short-chain fatty acids (SCFAs), polyamines, and tryptophan metabolites. Quantitative targeted metabolomics analysis of the serum revealed changes in specific classes of gut microbiota metabolites, including SCFAs, trimethylamine, polyamines, and indole-containing tryptophan metabolites. A marked decrease in indole-3-propionic acid (IPA) blood level was observed on D7. Changes in microbiota-associated metabolites correlated with changes in taxon abundance and disease marker levels. In particular, IPA was positively correlated with some Lactobacillaceae and Bifidobacteriaceae species (Limosilactobacillus reuteri, Lactobacillus animalis) and negatively correlated with Bacteroidales bacterium M7, viral load, and inflammation markers. IPA supplementation in diseased animals reduced viral load and lowered local (lung) and systemic inflammation. Treatment of mice with antibiotics targeting IPA-producing bacteria before infection enhanced viral load and lung inflammation, an effect inhibited by IPA supplementation. The results of this integrated metagenomic-metabolomic analysis highlighted IPA as an important contributor to influenza outcomes and a potential biomarker of disease severity.",

These signs of disrupted GI function can be associated with alterations in the gut microbiome. However, it is not known if long-access opioid self-administration has effects on the gut microbiome. We used 16S rRNA gene sequencing to investigate the gut microbiome in three independent cohorts (N=40 for each) of NIH heterogeneous stock rats before onset of long-access heroin self-administration (i.e., na\u00efve status), at the end of a 15-day period of self-administration, and after post-extinction reinstatement. Measures of microbial \u03b1- and \u03b2-diversity were evaluated for all phases. High-dimensional class comparisons were carried out with MaAsLin2. PICRUSt2 was used for predicting functional pathways impacted by heroin based on marker gene sequences. Community \u03b1-diversity was not altered by heroin at any of the three phases by comparison to saline-yoked controls. Analyses of \u03b2-diversity showed that the heroin and saline-yoked groups clustered significantly apart from each other using the Bray-Curtis (community structure) index. Heroin caused significant alterations at the ASV level at the self-administration and extinction phases. At the phylum level, the relative abundance of Firmicutes was increased at the self-administration phase. Deferribacteres was decreased in heroin whereas Patescibacteria was increased in heroin at the extinction phase. Potential biomarkers for heroin emerged from the MaAsLin2 analysis. Bacterial metabolomic pathways relating to degradation of carboxylic acids, nucleotides, nucleosides, carbohydrates, and glycogen were increased by heroin while pathways relating to biosynthesis of vitamins, propionic acid, fatty acids, and lipids were decreased. These findings support the view that long access heroin self-administration significantly alters the structure of the gut microbiome by comparison to saline-yoked controls. Inferred metabolic pathway alterations suggest the development of a microbial imbalance favoring gut inflammation and energy expenditure. Potential microbial biomarkers and related functional pathways likely invoked by heroin self-administration could be targets for therapeutic intervention.",

Recent studies have shown that common ginsenosides and rare ginsenosides (RGS) are the main active compounds in ginseng. RGS have higher activity and are less studied in the treatment of hyperuricemia. To determine whether RGS prevents and ameliorates potassium oxonate(PO)-induced hyperuricemia and concomitant spermatozoa damage in mice and the possible underlying mechanisms. Potassium oxonate (PO, 300\u00a0mg/kg) induced hyperuricemia in mice via the oral administration of RGS (50, 100, or 200\u00a0mg/kg) or allopurinol (ALL, 5\u00a0mg/kg) for 35 days. Uric acid (UA) and xanthine oxidase (XO) levels were measured to assess the degree of histopathological damage in the liver, kidney, and testis, and renal creatinine (CRE), urea nitrogen (BUN), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), and inflammatory factor (IL-1\u03b2) levels were measured to calculate the sperm density. Mechanisms were also explored based on blood and urine metabolomics and the gut microbiota. In this study, we demonstrated that RGS containing Rg3, Rk1, Rg6, and Rg5 could reduce serum UA levels, inhibit serum and hepatic XO activity, reduce renal CRE and BUN levels, further restore renal SOD and GSH activities, reduce the accumulation of MDA in the kidneys, and attenuate the production of renal IL-1\u03b2. RGS was able to restore sperm density. Metabolomic analysis revealed that RGS improved sphingolipid metabolism, pyrimidine metabolism, and other metabolic pathways. 16S rDNA sequencing revealed that RGS could increase gut microbial diversity, restore the Firmicutes/Bacteroidetes (F/B) ratio, and adjust the intestinal microbial balance. Spearman's correlation analysis revealed a correlation between differentially metabolites and the gut microbiota. Lactobacillus and Akkermansia are the core genera. RGS can be a candidate for the prevention and amelioration of hyperuricemia and concomitant sperm damage. Its mechanism of action is closely related to sphingolipid metabolism, pyrimidine metabolism, and the modulation of gut microbiota, such as Lactobacillus and Akkermansia.",

However, the potential protective mechanism of DF against potassium oxybate-induced hyperuricaemia (HUA), as modelled by prophylactic administration, remains unclear. The data demonstrate that DF significantly decreased serum and cerebral tissue UA concentrations, inhibited xanthine oxidase expression and activity in the liver and reduced levels of creatinine and urea nitrogen in the serum. Additionally, it mitigated the deposition of amyloid-\u03b2 in cerebral tissue. Correlation analysis showed that DF modulated the Toll-like receptor 4/NF-\u03baB signalling pathway, attenuating oxidative stress and inflammatory responses in HUA mice. Additionally, DF helps to maintain the composition of the gut microbiota, reducing harmful Desulfovibrio and enriching beneficial Akkermansia and Ruminococcus populations. The results of the faecal metabolomics analysis indicate that DF facilitates the regulation of metabolic pathways involved in oxidative stress and inflammation. These pathways include pyrimidine metabolism, tryptophan metabolism, nucleotide metabolism and vitamin B6 metabolism. Additionally, the study found that DF has a preventive effect on anxiety-like behaviour induced by HUA. In summary, DF shows promise in mitigating HUA and cognitive deficits, primarily by modulating gut microbiota and metabolites.",

Probiotics are increasingly used to support the improvement of the course of inflammatory diseases. In this study, we evaluated the potential of a lactic acid bacteria (LAB) combination containing Limosilactobacillus reuteri GMNL-89 and Lacticaseibacillus paracasei GMNL-133 to decrease lung inflammation and emphysema in a COPD mouse model. This model was induced by intranasal stimulation with elastase and LPS for 4\u00a0weeks, followed by 2\u00a0weeks of oral LAB administration. The results showed that the LAB combination decreased lung emphysema and reduced inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in the lung tissue of COPD mice. Microbiome analysis revealed that Bifidobacterium and Akkermansia muciniphila, reduced in the gut of COPD mice, could be restored after LAB treatment. Microbial \u03b1-diversity in the lungs decreased in COPD mice but was reversed after LAB administration, which also increased the relative abundance of Candidatus arthromitus in the gut and decreased Burkholderia in the lungs. Furthermore, LAB-treated COPD mice exhibited increased levels of short-chain fatty acids, specifically acetic acid and propionic acid, in the cecum. Additionally, pulmonary emphysema and inflammation negatively correlated with C. arthromitus and Adlercreutzia levels.

Plant-based dairy analogues have been increasingly popular due to their suitability for individuals with milk protein allergy or lactose intolerance and those preferring a plant-based diet. Nevertheless, plant-based products still have insufficient nutritional quality, undesirable structure, and earthy, green, and bean-like flavor compared to dairy products. In addition, most plant-based foods contain lesser amounts of essential nutrients, antinutrients limiting the bioavailability of some nutrients, and allergenic proteins. Novel processing technologies can be applied to have a homogeneous and stable structure. On the other hand, fermentation of plant-based matrix with lactic acid bacteria can provide a solution to most of these problems. Additional nutrients can be produced and antinutrients can be degraded by bacterial metabolism, thereby increasing nutritional value. Allergenic proteins can be hydrolyzed reducing their immunoreactivity. In addition, fermentation has been found to reduce undesired flavors and to enhance various bioactivities of plant foods. However, the main challenge in the production of fermented plant-based dairy analogues is to mimic familiar dairy-like flavors by producing the major flavor compounds other than organic acids, yielding a flavor profile similar to those of fermented dairy products. Further studies are required for the improvement of the flavor of fermented plant-based dairy analogues through the selection of special microbial cultures and formulations.",

HE staining combined with plasma biochemical indicators was used to evaluate renal pathological and functional changes. We conducted 16S rRNA sequencing and untargeted metabolomics on feces and plasma samples to reveale changes in intestinal microbiota and metabolites.Result: Our analysis revealed significant differences in 15 bacterial genera, with 7 being upregulated and 8 being downregulated. Furthermore, metabolomic analysis revealed changes in the distribution of amino acid and biotin metabolites in basic metabolic pathways in both feces and serum. Specifically, differentially abundant metabolites in feces were associated primarily with histidine metabolism; the biosynthesis of phenylalanine, tyrosine, and tryptophan; and tyrosine metabolism. In plasma, the differentially abundant metabolites were involved in multiple metabolic pathways, including aminoacyl-tRNA biosynthesis; glycine, serine, and threonine amino acid metabolism; valine, leucine, and isoleucine biosynthesis; tyrosine biosynthesis and metabolism; biotin metabolism; and taurine and hypotaurine metabolism. Furthermore, correlation analysis revealed that Akkermansia, UCG-005, Lachnospiraceae_NK4A136_group, Lactococcus, and Butymonas were associated with various differentially abundant metabolites as well as renal function, oxidative stress, and mitophagy. The changes in the intestinal flora observed in hyperuricemia may lead to imbalances in amino acid and biotin metabolism in both the intestine and host, ultimately affecting oxidative stress and mitophagy in mice and accelerating the progression of CKD.Conclusion: Our findings provide insights into a potential pathogenic mechanism by which hyperuricemia exacerbates renal injury in mice with renal insufficiency.

The lyophilized powder of Poecilobdella manillensis has been shown to significantly alleviate HUA; however, its underlying metabolic regulation remains unclear. To explore the underlying mechanisms of Poecilobdella manillensis in HUA based on modulation of the gut microbiota and host metabolism. A mouse model of rapid HUA was established using a high-purine diet and potassium oxonate injections. The mice received oral drugs or saline. Additionally, 16S rRNA sequencing and ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry-based untargeted metabolomics were performed to identify changes in the microbiome and host metabolome, respectively. The levels of uric acid transporters and epithelial tight junction proteins in the renal and intestinal tissues were analyzed using an enzyme-linked immunosorbent assay. The protein extract of Poecilobdella manillensis lyophilized powder (49 mg/kg) showed an enhanced anti-trioxypurine ability than that of allopurinol (5 mg/kg) (P < 0.05). A total of nine bacterial genera were identified to be closely related to the anti-trioxypurine activity of Poecilobdella manillensis powder, which included the genera of Prevotella, Delftia, Dialister, Akkermansia, Lactococcus, Escherichia_Shigella, Enterococcus, and Bacteroides.

Regarding COPD, studies have shown that GM alterations could be related the stages of this disease. However, the relationship between GM and clinical, biochemical and immunological parameters in patients with COPD are not well understood. The aim of this study was to compare the relative abundance of specific groups of beneficial gut bacteria between COPD patients and healthy controls (CTLs) in order to evaluate relationships with metabolic and inflammatory markers in COPD. We included 16 stable COPD patients and 16 healthy volunteer CTLs. The relative abundances of Bifidobacterium spp. (Bf) and Akkermansia muciniphila (Akk) bacteria and the Bacteroidetes and Firmicutes phyla were assessed by qPCR. Pulmonary function was evaluated by spirometry, biochemical parameters by colorimetric methods and plasma cytokine levels by cytometric bead array analysis. The Firmicutes/Bacteroides ratio was related to emergency hospital visits and six-minute walk test (6MWT) results. Furthermore, the relative abundance of Bf was associated with plasma concentrations of glucose, triglycerides, HDL-C and IL-10. In addition, Firmicutes levels and the Firmicutes/Bacteroidetes ratio were associated with the IL-12/IL-10 ratio, while Akk abundance was linked to IL-12 levels. The present findings suggest that the abundance of beneficial bacteria in the GM could influence clinical presentation and immunoregulation in COPD.",

Biochemically and pathologically, Liu et al proved that the urate-lowering activity of leech total protein (LTP) was mainly attributed to the rectification of gut microbiota. Specifically, we noticed the change in Bacteroides and Akkermansia after LTP administration. Both bacteria have been reported to alleviate metabolic dysfunction-associated steatohepatitis and other chronic metabolic diseases. LTP was administrated through intragastric manners. Most possibly, LTP would be digested by the gut microbiota further. The anti-hyperuricemia effects should, to the most possible extent, be exerted by the peptides or their secondary metabolic products. Human gut microbiota communicates with other organs through metabolites generated by the microbes or co-metabolized with the host. Whether the anti-hyperuricemia effect could be partially ascribed to the microbiota metabolites also deserves to be discussed. Although metabolomics analysis was performed for serum samples, fecal metabolomics was highly advocated which could facilitate exact mechanism explanation. This study implied that gut microbiota contains many unexplored targets with different therapeutic potentials. It is foreseeable that utilizing these targets can avoid the impairment or side effects of directly using human targets to some extent.",

Coix seed, a traditional cereal, has shown therapeutic potential against HUA, with oligosaccharides serving as its primary active components. However, the mechanisms of Coix seed oligosaccharides in HUA management remain underexplored. In this study, a novel oligosaccharide was isolated from Coix seed (CSO) through enzymatic hydrolysis and column chromatography. Structural analysis revealed that the CSO is primarily composed of glucose, with a backbone of \u21924)-\u03b2-Glcp-(1\u2192 linkages. CSO exhibited significant hypouricemic effects in both adenosine-induced HK-2 cells and HUA mice by inhibiting XOD activity and regulating urate transporter expression. Furthermore, CSO restored lipid imbalances, particularly in PS and PC, and modulated gut microbiota by increasing Ruminococcus, Akkermansia, and Lachnospiraceae abundance to alleviate HUA-related systemic disturbances. Importantly, CSO alleviated HUA-induced renal injury by downregulating the IL-6/JAK2/STAT3 signaling pathway. This study provided meaningful evidence supporting the effect of CSO on HUA and offered new directions for natural oligosaccharide interventions in metabolic health.",

Our previous laboratory studies have shown that Pu-erh tea could alleviate CRD-induced syndromes, including obesity, intestinal dysfunction, and tryptophan metabolism disorders. However, its potential protective mechanism against CRD-induced hyperuricaemia remains unclear. In this work, we found that polyphenols of Pu-erh tea were significantly released in the stage of intestinal digestion, which might promote their interaction with gut microbes. Through animal experiments, C57BL6/J mice were given water or different doses of Pu-erh tea for 60 days, followed by a 90-day CRD, the lifestyle of modern individuals who frequently stay up late. Our results indicated that CRD mice exhibited high serum uric acid levels and gut microbiota disorders. Pu-erh tea intake significantly reshaped the gut microbiome, especially increasing the abundance of Bifidobacterium, Akkermansia and Faecalibaculum, and increased the production of short-chain fatty acids (SCFAs), especially acetic acid, which restored the function of the intestinal barrier. This improvement further regulated oxidative stress pathways (NRF2/HO-1), reduced systemic inflammatory response (IL-6, IL-1\u03b2, and TNF-\u03b1), restored hepatic function (SOD, MOD, CAT, and GSH) and modulated the activity of enzymes related to UA metabolism in the liver (XOD and ADA). Finally, Pu-erh tea intake promoted the excretion of UA and reduced the levels of UA and xanthine in the serum. Moreover, the results of antibiotic experiments showed that the UA improvement effect of Pu-erh tea depended on the existence of the gut microbiota. Collectively, Pu-erh tea intake has the potential to prevent CRD-induced hyperuricaemia by reshaping the gut microbiota.",
        "40136712": "ID: 40136712\nTitle: Impact of a High-Fat Diet on the Gut Microbiome: A Comprehensive Study of Microbial and Metabolite Shifts During Obesity.\nAbstract: Over the last few decades, the prevalence of metabolic diseases such as obesity, diabetes, non-alcoholic fatty liver disease, hypertension, and hyperuricemia has surged, primarily due to high-fat diet (HFD). The pathologies of these metabolic diseases show disease-specific alterations in the composition and function of their gut microbiome. How HFD alters the microbiome and its metabolite to mediate adipose tissue (AT) inflammation and obesity is not well known. Thus, this study aimed to identify the changes in the gut microbiome and metabolomic signatures induced by an HFD to alter obesity. To explore the changes in the gut microbiota and metabolites, 16S rRNA gene amplicon sequencing and metabolomic analyses were performed after HFD and normal diet (ND) feeding. We noticed that, at taxonomic levels, the number of operational taxonomic units (OTUs), along with the Chao and Shannon indexes, significantly shifted in HFD-fed mice compared to those fed a ND. Similarly, at the phylum level, an increase in Firmicutes and a decrease in Bacteroidetes were noticed in HFD-fed mice. At the genus level, an increase in Lactobacillus and Ruminococcus was observed, while Allobaculum, Clostridium, and Akkermansia were markedly reduced in the HFD group. Many bacteria from the Ruminococcus genus impair bile acid metabolism and restrict weight loss. Firmicutes are efficient in breaking down complex carbohydrates into short-chain fatty acids (SCFAs) and other metabolites, whereas Bacteroidetes are involved in a more balanced or efficient energy extraction. Thus, an increase in Firmicutes over Bacteroidetes enhances the absorption of more calories from food, which may contribute to obesity. Taken together, the altered gut microbiota and metabolites trigger AT inflammation, which contributes to metabolic dysregulation and disease progression. Thus, this study highlights the potential of the gut microbiome in the development of therapeutic strategies for obesity and related metabolic disorders.",

Methods: The fatty acid composition of YRO was determined by gas chromatography-mass spectrometry (GC-MS). A HUA mouse model was established, and serum markers and hepatic enzymes were evaluated. Renal mitochondrial function was assessed using immunohistochemistry and immunofluorescence, and urate transporter expression, along with key signaling proteins, was quantified by Western blot analysis. Additionally, gut microbiota composition was analyzed, and non-targeted metabolomics was performed to observe alterations in serum lipid metabolites. Results: YRO significantly reduced serum uric acid (UA) levels and normalized hepatic enzyme activities. Histological evaluation revealed less tissue damage in both the kidney and the intestine. In the kidney, YRO improved mitochondrial function and supported antioxidant defenses via regulation of Keap1/Nrf2 signaling. In the intestine, YRO enhanced barrier integrity by increasing ZO-1, Occludin, and Claudin-1 expression. Moreover, YRO modulated gut microbiota by increasing beneficial bacteria (Muribaculaceae, Prevotellaceae UCG-001, Lachnospiraceae_ NK4A136_group, Akkermansia) while suppressing harmful species (Bacteroides, Dubosiella). Lipid metabolomics indicated a restoration of phospholipid balance through modulation of the PI3K/AKT/mTOR pathway. Conclusions: YRO supported metabolic health by promoting UA homeostasis, enhancing mitochondrial function, reinforcing antioxidant capacity, and maintaining gut integrity. These findings suggest that coix seed oil could serve as a nutritional supplement in managing HUA and related metabolic disturbances.",
        "40616741": "ID: 40616741\nTitle: Gout, Hyperuricemia, and the Intestinal Microbiome.\nAbstract: Gout is a disease of hyperuricemia (HU) leading to monosodium urate crystal deposition in the joint, resulting in inflammation and joint damage. Recently, efforts have been made to characterize the intestinal microbiome of patients who suffer from HU and gout, and pre-clinical studies have evaluated the utility of prebiotics and probiotics in alleviating gout. Herein we review recent notable studies addressing these topics. In brief, the \"gouty\" microbiome is characterized by reduced diversity, an elevated Bacteroides: Firmicutes ratio, and reduced presence of Akkermansia and Bifidobacterium. In anserine models, supplementation with Lactobacillus probiotic strains appears to reduce serum urate (SU) and HU-induced inflammation. Murine models suggest that the chicory-derived prebiotic inulin may reduce SU, and oral supplementation with the anti-inflammatory short-chain fatty acid butyrate may lower SU by enhancing urate excretion and alleviate HU-induced tissue inflammation. Many of these studies are limited by modest numbers of participants and/or incompletely documented experimental controls, and, in the case of animal models, questionable reproducibility in humans. Many studies have been geographically limited. There remains a need for more information regarding the features of the \"gouty\" microbiome in wider populations, as well as for additional well-controlled probiotic and prebiotic studies in more physiologically relevant animal models prior to clinical trials.",

However, toxicological studies of BIT in aquatic organisms are still limited. This study exposed zebrafish embryos to 0, 1, 10, 100, and 1000 \u03bcg/L BIT for 14 days, and investigated the effect of BIT on the innate immune function of larval fish. 16S rRNA sequencing revealed that BIT exposure reduced microbial diversity and richness, while increased pathogenic genera like Plesiomonas and Acinetobacter in larval fish. Then, the intestinal structure and gut barrier function were impaired, and the elevated lipopolysaccharides levels activated the Toll-like receptor signaling pathway and triggered a pro-inflammatory innate immune response in zebrafish. The ability of zebrafish to resist pathogen infection was further impaired, as indicated by a failed recruitment of macrophages in the intestinal area after Escherichia coli infection. Whereas, dietary administration of probiotic Lactobacillus rhamnosus ameliorated the immunotoxicity of BIT, and restored the zebrafish larvae' immunity against pathogens. These findings elucidated the adverse effect of BIT on the innate immune function of larval zebrafish from the perspective of intestinal health and microbial disruption, and also provided insights into probiotic-based strategies for mitigating isothiazolinone biocides toxicity in aquatic organisms.",

Current pharmacotherapies face limitations due to adverse effects during prolonged use. Natural medicines like Radix Puerariae Lobatae have demonstrated therapeutic potential with superior safety profiles. This study investigated the anti-hyperuricemic efficacy of compound Puerariae lobatae formulas (PLF1 and PLF2) and their bioactive component puerarin, focusing on their mechanisms for enhancing renal/intestinal uric acid excretion, alleviating pathological damage, and modulating gut microbiota composition. A hyperuricemic mouse model was established using an adenine/potassium oxonate diet. Mice were treated with PLF1 (250/500 mg/kg), PLF2 (300/600 mg/kg), puerarin (100 mg/kg), or benzbromarone (40 mg/kg, positive control). Plasma and tissue uric acid levels, XOD and ADA activities, and renal/intestinal transporter expression (ABCG2, OAT1) were analyzed. Histopathological examinations were performed using HE staining to assess kidney, liver, and intestinal integrity. Gut microbiota composition was evaluated via PacBio Sequel II 16S rRNA sequencing. Antibiotic-induced microbiota depletion and fecal microbiota transplantation (FMT) approaches were employed to validate microbiota-dependent effects. PLF1, PLF2, and puerarin significantly reduced plasma uric acid levels and suppressed XOD/ADA activities. Histopathological analysis demonstrated marked improvements in renal tubular injury, hepatic steatosis, and intestinal structural integrity, including restoration of villus architecture and crypt morphology. The expression of renal ABCG2 and OAT1, as well as intestinal ABCG2, was significantly upregulated, accompanied by enhanced expression of colonic tight junction proteins (ZO-1 and occludin). Antibiotic-induced microbiota depletion abolished the hypouricemic effect of puerarin, while FMT from puerarin-treated donors significantly alleviated hyperuricemia in recipient mice. Gut microbiota analysis revealed that both PLF2 and puerarin selectively enriched the beneficial bacterium Akkermansia muciniphila while simultaneously reducing pathogenic taxa. This study establishes Puerariae lobatae formulas and puerarin as multi-target therapeutics for hyperuricemia, offering dual advantages over conventional drugs by enhancing renal/intestinal uric acid excretion while also repairing organ damage, and remodeling gut microbiota to enrich probiotics like A. muciniphila. The microbiota-dependent efficacy of puerarin not only underscores its potential as a novel natural therapeutic agent but also provides critical pharmacological evidence for advancing puerarin and Radix Puerariae Lobatae-based formulas in hyperuricemia treatment, bridging traditional herbal medicine with modern microbiota-targeting strategies.",

Akkermansia muciniphila (A. muciniphila), a next-generation probiotic, shows promise in promoting intestinal homeostasis and metabolic regulation. Previous studies have demonstrated the potential application of A. muciniphila in ULT, but its specific mechanism has not been elucidated. In this study, we isolated a strain of A. muciniphila, named K101, from the cecum of goslings. In vitro experiments showed that K101 directly degrades uric acid, suggesting a potential microbial-metabolic crosstalk mechanism for anti-HUA. In vivo experiments showed that K101 increased the abundance of uric acid metabolism-related microbiota, such as A. muciniphila and Lactobacillus. Functionally, K101 synergistically promoted uric acid excretion by activating the intestinal excretory protein ABCG2 and inhibiting the renal uric acid reabsorption protein GLUT9. In addition, K101 provides a stable environment for uric acid metabolism by inhibiting renal inflammatory responses. Overall, A. muciniphila K101 exerts anti-HUA effects by remodeling the intestinal microbiota and excretion of uric acid through the gut-renal axis. This study offers new insights into microbial-metabolic crosstalk in uric acid metabolism in A. muciniphila and identifies potential targets for gout prevention and ULT strategy development.IMPORTANCEThe rising prevalence of hyperuricemia (HUA) underscores the need for new therapies and treatment approaches. Our study highlights the developmental and therapeutic potential of natural uric acid-degrading bacteria discovered in the avian gut, expanding the range of bacteria with possible medical applications. Another key finding is the notable efficacy of microbiota metabolites in alleviating HUA. While the underlying mechanisms warrant further investigation, these findings offer promising insights into microbiota-based therapeutics.",

However, limited information is available regarding its potential toxicological effects on non-target soil organisms, particularly concerning enantioselective metabolic perturbations. In this study, the enantioselective toxicity of TEB on earthworms (Eisenia fetida) was investigated over a 20-day exposure at 5\u202fmg/kg using a multi-omics approach that integrated transcriptome, metabolome, and microbiota analysis. Phenotypic analysis revealed that R-(-)-TEB accumulated preferentially than S-(+)-TEB (p\u202f<\u202f0.05), and was distributed widely across the digestive tract and hindgut, whereas S-(+)-TEB was concentrated in the anterior digestive system. S-(+)-TEB induced more severe oxidative stress, as higher MDA level, disrupted antioxidant enzyme activities, and muscle damage. Transcriptomic and metabolomic integrative analysis revealed R-(-)-TEB primarily disrupted nucleotide metabolism, leading to impaired nucleic acid synthesis and energy supply, while S-(+)-TEB uniquely perturbed carbohydrate metabolism and downregulated CYP450-mediated external pollutant metabolism, leading to energy metabolic imbalance and the reduced capacity for pollutant biotransformation. Gut microbiota exhibited enantioselective responses to enhanced stress protection. Collectively, these findings provide insights into the toxicological mechanisms of TEB on earthworms at the enantiomeric level, and underscore the metabolic health risks posed by chiral fungicide exposure in soil environments.",

A traditional Chinese medicine formula, known as the Qihuang Biwen decoction (QHBW), has been shown to have immunomodulatory benefits in clinical and experimental studies. Nevertheless, few studies have investigated the effects of microbial-fermented QHBW (FQHBW) on immunity. In this study, we used one-way and Plackett-Burman analyses to establish the preparation process of FQHBW (crucial parameters: ratio of bacterial strains LZU-J-TSL6 and LZU-S-ZCJ was 3:1, inoculum quantity was 3%, temperature was 37\u2103, time was 37\u00a0h). The study found that FQHBW has increased total polysaccharide, total acid, and antioxidant capacities. The increased constituents after fermentation potentially contribute to improving the ability of FQHBW to regulate immunity. Next, its immunostimulatory activity was evaluated in cyclophosphamide (CTX)-treated mice, and the possible mechanism was studied by microbiome-metabolome analysis. As expected, FQHBW effectively ameliorated CTX-induced immunosuppression by improving organ index, lymphocyte proliferation, phagocytic function, cytokine secretion, and antioxidant profile. It protected against CTX-induced intestinal dysbiosis by promoting the abundance of Oscillospira, Allobaculum, and Coprococcus, while moderately increasing Akkermansia and reducing Staphylococcus and Streptococcus. FQHBW primarily influenced amino acid and nucleotide metabolism to benefit immunity. Unlike QHBW, FQHBW uniquely up-regulates dopamine synapses, tryptophan metabolism, and nicotinate and nicotinamide metabolism, promoting host anti-oxidation, immune system remodeling, and disease resistance. This study suggests that microbial fermentation is indeed an effective strategy to alter the properties and function of QHBW. FQHBW has the potential to replace QHBW as a novel immunoenhancer and intestinal microecological regulator.",

However, the pathways by which food-derived components mediate host collagen synthesis via the gut microbiota remain unclear. This study investigated the regulatory role of gut microbiota in collagen synthesis within the body wall of the sea cucumber (Apostichopus japonicus) under dietary supplementation. The results showed that the groups supplemented with 0.60% choline (DJ), 0.50% betaine (TC), and 2.75% glycine (G) significantly increased the collagen content in the sea cucumber body wall by 8.82%, 21.28%, and 22.13%, respectively, compared to the control group (NC). The composition and metabolic function of the sea cucumber gut microbiota were altered by dietary supplementation. The dominant gut microbiota in the supplemented group were Achromobacter, Ferrimonas, Shewanella, and Haloferula, which possess capabilities in amino acid metabolism and the decomposition of organic carbon and nitrogen sources. In addition, metabolic pathways such as amino acid metabolism, carbohydrate metabolism, energy metabolism, and nucleotide metabolism were significantly enriched. Glycine and other key collagen precursors exhibited significantly elevated levels in the gut of supplemented sea cucumbers. Research indicates that dietary supplementation with choline, betaine, and glycine modulates the composition and function of the gut microbiota in sea cucumbers.

Polysaccharide Attenuated Inflammatory Response and Intestinal Flora Dysbiosis in LPS-Induced Acute Lung Injury in Mice.\nAbstract: Background/Objectives: Acute lung injury (ALI) represents a life-threatening respiratory syndrome characterized by dysregulated pulmonary inflammation, alveolar-capillary barrier dysfunction, and gut-lung axis impairment. Although Lycium ruthenicum polysaccharide (LRP) possesses documented anti-inflammatory properties, its role in ALI remains systematically unexplored. This study aimed to investigate the protective effects of LRP against lipopolysaccharide (LPS)-induced ALI. Methods: In vitro, A549 cells were subjected to injury induction with 10 \u03bcg/mL LPS. In vivo, male C57BL/6J mice were randomly allocated to four groups and, respectively, administered 100 mg/kg LRP, 400 mg/kg LRP, or normal saline for 7 days prior to ALI induction via intratracheal LPS instillation (5 mg/kg). Results: LRP restored viability in LPS-injured A549 cells and attenuated their inflammatory responses. Histopathological analysis demonstrated that high-dose LRP (H-LRP) significantly reduced alveolar collapse and inhibited inflammatory cell infiltration in bronchoalveolar lavage fluid (BALF) compared to the LPS group. The H-LRP group exhibited marked downregulation of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6) concomitant with upregulation of the anti-inflammatory cytokine IL-10. Intestinal microbiome sequencing confirmed LRP-mediated restoration of gut microbiota homeostasis, evidenced by a 2.2-fold increase in commensal Bacteroides and decreased abundance of pathogenic Escherichia-Shigella. Conclusions: These findings establish LRP as a protective agent against ALI and suggest its potential utility as an adjuvant therapeutic candidate for enhanced pulmonary protection.",

It is essential to develop effective ways such as utilizing natural products as therapeutic agents for prevention and therapy of Pb-induced diseases. This study explores the effects and underlying mechanisms of astaxanthin (ATX), a natural compound with potent antioxidant properties, in alleviating Pb-induced toxicity in model mice. Supplementation with ATX significantly ameliorated lead-induced physiological and biochemical disruptions, including weight loss, hepatic and renal damage, and metabolic imbalances. Metabolomic and transcriptomic analyses revealed that ATX played a positive role in improving redox homeostasis, regulating lipid, amino acid, and nucleotide metabolism, and activating critical pathways such as Nrf2/ARE, PPAR, and S1P, thereby enhancing the antioxidative, anti-inflammatory, and detoxification capacities of the mice. ATX supplementation also modulated mouse gut microbiota by promoting beneficial bacterial populations, suppressing harmful strains, and increasing short-chain fatty acid production, thereby effectively restoring gut-liver axis balance. These findings demonstrate that ATX possesses comprehensive activities against lead toxicity via multi-dimensional regulatory mechanisms, highlighting ATX as a promising therapeutic agent for heavy metal poisoning. Further research is warranted to validate the clinical applications of ATX and evaluate its long-term safety.",

Quinoa processing and cooking alters its chemical composition and bioavailability of nutrients, and while extracts have been studied, little is known about the impact of quinoa food products on the human gut microbiota. One selected quinoa line was tested in raw, boiled, extruded, and baked (cookie) forms for its ability to modulate fecal microbiota from 10 healthy donors. After in vitro digestion, samples underwent fecal fermentation with measurements taken at 0, 6, 12, 24, and 48\u00a0h (h). Boiled and extruded quinoa exhibited significantly higher total polyphenol content when compared to raw quinoa (p\u00a0<\u00a00.05), while baked quinoa had lower polyphenol content, though the difference was not significant. Fecal fermentation of pre-digested raw and processed quinoa significantly increased (p\u00a0<\u00a00.05) beneficial lactic acid-producing bacterial (LAB) genera, including Bifidobacterium and Lactobacillus. All quinoa samples (raw, boiled, extruded, and baked) significantly increased Bifidobacterium abundance from 6 to 48\u00a0h compared to the start of fermentation (0\u00a0h), while Lactobacillus increased significantly in boiled, baked, and extruded samples at 12-48\u00a0h. Pediococcus and Weissella were more abundant in raw quinoa, suggesting that less-processed plant material might be harder to ferment. These findings highlight quinoa's prebiotic properties, which are largely preserved across various cooking methods. Future studies on quinoa and other grain products should integrate food chemistry and gut microbiota outcomes to identify physicochemical properties that influence microbiota responses.",

To elucidate the biological basis underlying differences in laying performance, this study employed 16S rRNA high-throughput sequencing and untargeted liquid chromatography-mass spectrometry (LC-MS/MS) to analyze the gut microbiota and serum metabolome of low-producing (LP) and high-producing (HP) Shanma ducks. The LP and HP groups exhibited significant differences in egg production performance, body size parameters, and slaughter traits. Firmicutes were the dominant phylum in the gut microbiota of both groups. However, Actinobacteria were significantly enriched in the HP group, while Campylobacter was more abundant in the LP group. Correlation analysis revealed a negative association between Campylobacter abundance and egg production, whereas Corynebacterium (belonging to Actinobacteria) showed a positive correlation. Non-targeted serum metabolomic analysis indicated that the differentially expressed metabolites were primarily enriched in nucleotide metabolism, choline metabolism, and glycerophospholipid metabolism pathways. Notably, Campylobacter abundance was negatively correlated with the levels of key metabolites involved in these pathways. Mantel analysis further confirmed a strong correlation between egg production and both gut microbiota composition and serum metabolomic profiles.

The Yi-Qi-Xuan-Fei Formula (YQXF) is a clinically effective formula with pharmacological potential to delay the progression of COPD. This study aims to explore the relationship between the therapeutic mechanism of YQXF and the microflora in COPD. Our study found that YQXF reduces inflammatory injury and inflammatory cell infiltration in lung tissue, repairs the intestinal mucosal barrier, and enhances immune function. Additionally, YQXF regulates the pulmonary and intestinal flora by increasing the abundance of Alloprevotella, Roseburia, Oscillibacter, and Lactobacillus, while reducing the abundance of Fusobacterium, Escherichia/Shigella, and Clostridium sensu stricto. Moreover, YQXF elevates the levels of short-chain fatty acids, which are produced by the intestinal flora. In conclusion, our findings demonstrate that YQXF reduces inflammation levels in lung tissue and repairs the intestinal barrier in COPD rats. Furthermore, the anti-inflammatory and tissue damage prevention effects of YQXF are based on its intervention in the pulmonary and intestinal flora. These findings provide valuable insights into the fundamental mechanism of the herbal formula YQXF and suggest that specifically targeting the intestinal flora could be a potential therapeutic approach for COPD.",

Endogenous purine biosynthesis and purinosome formation are neglected in research of medical mechanism. In this study, the therapeutic effect and mechanism of metformin was explored in chronic high-fructose-induced hyperuricemic rats. Results indicated that four weeks of metformin administration effectively reduced uric acid (UA), creatinine, and urea levels, ameliorated renal and hepatic injuries, and promoted glycogen synthesis in hyperuricemic rats. Furthermore, metformin remarkedly downregulated the mRNA and protein expression of core enzymes in pentose phosphate pathway (PPP), and de novo purine biosynthesis (DNPB) of endogenous purine. Metformin was found to markedly inhibit the purine salvage pathway (PSP) and XOD to retard purine recycling and metabolism. Additionally, metformin effectively restored physiological purinosome architecture, preventing aberrant enzyme clustering and subcellular redistribution. The hepatic levels of IMP, inosine, hypoxanthine and xanthine in hyperuricemic rats were remarkably decreased by metformin. Besides, metformin favorably maintained the gut microbiome homeostasis and normalized purine metabolism to lower purine levels in intestine. Taken together, the results for the first time indicated that metformin exerted appreciable anti-hyperuricemic effect, at least partly, via inhibiting original biosynthetic and metabolic pathways of endogenous purine simultaneously mediated by PPP/DNPB/XOD, purinosome assembly, and modulating gut microflora profile. This work provided a scientific basis for its potential application in hyperuricemia therapy beyond its classical use in diabetes.",

We first validated the CRISPRi-based approach using Bifidobacterium breve strains engineered to express nuclease-dead orthologs of Cas9 and demonstrated that the CRISPR-Cas system from Streptococcus thermophilus is efficient at targeting both reporter and endogenous genes through the use of single guide RNAs corresponding to the gene of interest. We also developed a one-plasmid system for targeted gene repression in bifidobacteria and demonstrated its utility by targeting genes involved in nucleotide metabolism and carbohydrate metabolism in several species of bifidobacteria. Efficient gene repression was achieved across all tested bifidobacterial species without the requirement for extensive optimization of transformation parameters or sequence optimization to avoid restriction modification systems thus removing the key barriers to genetic manipulation in this genus. This CRISPRi system provides a novel approach to functional genomics in bifidobacteria which facilitates future mechanistic studies in these commercially important microbes.",

Fecal samples were collected from 15 patients diagnosed with IDD, classified according to the Pfirrmann grading system, with a distribution of three individuals per grade. Additionally, samples were obtained from five healthy controls for comparative analysis. 16S\u00a0rDNA sequencing was employed to analyze gut microbiota composition, while liquid chromatography-mass spectrometry was used for untargeted metabolite profiling. Distinct gut microbiota signatures were observed in IDD patients compared to controls, characterized by a dysbiotic state with increased biodiversity. More importantly, patients with IDD exhibit a higher abundance of Proteobacteria and Fusobacteriota, along with reduced abundances of Campilobacterota and Synergistota at the phylum level, as determined by Linear Discriminant Analysis Effect Size (LEfSe). Fecal metabolite analysis revealed an altered metabolic profile in IDD patients, including aggrandized levels of lipids and lipid-like molecules, which are associated with oxidative stress and tissue degradation. KEGG pathways identified five significant ones, including Nucleotide metabolism, Taurine and hypotaurine metabolism, Arginine and proline metabolism, Carbohydrate digestion and absorption, and FoxO signaling pathway. Together with receiver operating characteristic analysis, our data indicate that the upregulation of Permethrin and the reduction of 3ccPA, Thymine, His-ser, Hypoxanthine, N6-Acetyl-L-lysine, Safranin, and Peimine are highly associated with IDD. Our findings suggest a strong association between gut microbiota dysbiosis and fecal metabolite alterations in the pathogenesis of IDD.",

Current therapeutic approaches (e.g., acid-suppressive agents, mucosal protectants) are limited by side effects and suboptimal bioavailability, while conventional extraction of herbal medicines (e.g., Honeysuckle-Cassia seeds) yields low bioactive compound solubility. This study explored the potential of Lactobacillus acidophilus and Bacillus subtilis co-fermented Honeysuckle-Cassia seed extracts in mitigating AGMD. In vitro antioxidant assays revealed that mixed bacterial fermentation extract (MBF) exhibited superior scavenging activity against superoxide anion (86.14\u00a0%), ABTS (88.11\u00a0%), and DPPH (42.96\u00a0%) radicals compared to unfermented aqueous extract (AE) and single-strain fermented extract (LAF). In vivo experiments in ethanol-induced AGMD mice showed that MBF significantly restored gastric mucosal redox balance, reducing MDA levels by 60.92\u00a0% and enhancing SOD activity and GSH content. Mechanistically, MBF suppressed neutrophil infiltration (MPO \u219361.36\u00a0%) and pro-inflammatory cytokines (IL-1\u03b2, TNF-\u03b1, IL-6), while upregulating tight junction proteins (ZO-1, Claudin-1, Occludin) to protect mucosal integrity. These protective effects were mainly mediated by modulation of the MAPK signaling axis-specifically, inhibiting JNK/p38 and activating ERK-thereby enhancing antioxidant defenses and maintaining tight junction integrity. These findings indicate that probiotic fermentation significantly enhances the therapeutic potential of herbal formulations. Importantly, given its safety and efficacy, MBF may be further developed as a functional food, nutraceutical, or adjunctive dietary therapy to prevent alcohol-related gastric injury, offering a sustainable and food-based preventive strategy.",

Compared to conventional lysozyme, yak stomach lysozyme (YSL) demonstrates distinctive resistance to pepsin, trypsin, high temperature, and acidic conditions. This study investigated the effects of dietary YSL supplementation on intestinal health in weaned piglets challenged with ETEC, utilizing metabolomics and proteomics. A total of 18 weaned piglets were randomly divided into three groups: control (C), diarrhea (D), and YSL treatment (YLT). Groups C and D were fed a basal diet, while the YLT group received the basal diet supplemented with YSL at a dosage of 100,000 U/kg following ETEC challenge. Following an acclimation period, piglets in groups D and YLT were orally challenged with ETEC, while group C received the same volume of sterile LB broth. The feeding trial lasted for 21 days before sample collection. The results demonstrated that dietary supplementation with YSL significantly reduced the diarrhea rate (p < 0.05). Compared with the D group, the YLT group exhibited significantly increased serum albumin levels (p < 0.05), along with a tendency toward greater villus height (p = 0.085) and higher serum glucose levels (p = 0.052), indicating an improvement in nutritional and metabolic status Metabolomic analysis identified 260 differentially abundant metabolites between the YLT and D groups (81 upregulated, 179 downregulated), which were predominantly enriched in pathways related to amino acid biosynthesis and metabolism, purine metabolism, and nucleic acid metabolism. Proteomic profiling revealed 571 differentially expressed proteins (237 upregulated, 334 downregulated). Upregulated proteins were mainly involved in arginine biosynthesis and base excision repair, while downregulated proteins were associated with the PPAR signaling pathway and Salmonella infection. In summary, dietary YSL supplementation alters the metabolic and proteomic profiles in the intestines of diarrheic piglets, potentially improving gut barrier function and nutrient utilization. This study offers novel insights into the potential of YSL as a promising feed additive for prevention of post-weaning diarrhea in pigs.",

These strains are associated with more specific functions, including mucin degradation, butyrate production, enhanced gut barrier integrity, immune regulation, and modulation of host metabolism and inflammation. Unlike conventional probiotics, which mainly promote general digestive balance, NGPs demonstrate targeted mechanisms that link them to metabolic, inflammatory, and even neurological conditions. This review provides a critical comparison of traditional and NGPs, highlighting mechanistic distinctions and functional advancements. It also explores recent innovations in synthetic biology, including programmable gene circuits, and examines how artificial intelligence and microbiome profiling are paving the way toward personalized probiotic therapies, though widespread clinical application remains in its early stages. Key safety, regulatory, and translational challenges are also addressed, outlining barriers to clinical adoption.

Diet is considered a primary route of exposure to both microplastics (MPs) and cadmium (Cd), raising concerns about their potential joint impacts on child health. However, the effects of combined exposure to MPs and Cd on the early-life gut microbiota remain poorly understood. Fecal samples from 68 preschool children under 6 years of age were analyzed using pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) and inductively coupled plasma mass spectrometry (ICP-MS) to quantify MPs and Cd, respectively. MPs were detected in all samples, with a median concentration of 123.7\u202f\u03bcg/g dry weight (DW) (interquartile range, IQR: 70.6-197.8). The predominant polymers were polyethylene (PE, 100\u202f%), polyamide-66 (PA66, 100\u202f%), and polyvinyl chloride (PVC, 93\u202f%). Cd was also detected in all children, with a median concentration of 0.31\u202f\u03bcg/g DW (range: 0.21-0.48). Cd concentrations were significantly higher in the low-MP-exposure group compared to the high-exposure group, indicating an inverse association between fecal MP and Cd levels in children. Under combined exposure to MPs and Cd, children with lower Cd levels exhibited higher abundances of beneficial taxa, such as Bifidobacterium and Faecalibacterium. In contrast, higher MP exposure was associated with enrichment of Bacilli and enhanced Bacilli-associated functional activity, particularly in amino acid, energy, and carbohydrate metabolism. KEGG functional predictions also showed that carbohydrate and nucleotide metabolism pathways are more prominent in both low Cd-MP and high Cd-MP exposure groups, indicating a non-monotonic trend. These findings provide novel evidence that combined exposure to MPs and Cd is associated with distinct alterations in the gut microbiota of preschool children, underscoring the need to consider multiple pollutants in early-life microbiome research.",

Targeted therapies, including immune checkpoint inhibitors (ICIs), phosphatidylinositol 3-kinase (PI3K) inhibitors and EGFR-tyrosine kinase inhibitors (TKIs), are both influenced by and themselves influence the patients' nutritional and metabolic status. Precision nutrition approaches that address specific aspects of targeted therapies, from minimizing toxicities and treatment resistance to potential therapeutic synergies, offer an important avenue to optimize clinical outcomes for patients receiving targeted oncological treatments as a part of an overall precision integrative oncology approach. Optimizing ICI treatment may necessitate gastrointestinal microbiome modulation and managing systemic inflammation with a variety of dietary approaches under study, including the Mediterranean diet, increasing fiber and fermented food intake, fasting and fasting mimicking diet and the ketogenic diet. Supplementation approaches using live biotherapeutics alongside ICIs predominate over prebiotic, postbiotic and synbiotic studies, which require further attention and investment, alongside human research on mycotherapy and fucoidan-based combinations. Optimizing PI3K treatment tolerance requires close attention to monitoring and managing glycemic control through nutrition, lifestyle and pharmacological intervention as necessary, and in supporting patients with EGFR-TKIs both nutritional prehabilitation and close attention to managing gastrointestinal toxicities is paramount. Rational individualized approaches based on detailed and dynamic clinical assessment of patient-, cancer- and treatment-related factors, using validated prognostic scores and biomarkers, are needed to maximize the potential of precision nutrition now and in future trials in this arena.",

While current therapies provide symptomatic relief, they fail to modify disease progression, with early diagnosis remaining challenging due to nonspecific clinical presentations. Emerging evidence has established the gut microbiota as a vital modulator of COPD pathogenesis via the microbiota-gut-lung axis, which is mediated through dysregulated short-chain fatty acid metabolism, bidirectional inflammatory cytokine regulation, and compromised mucosal barrier integrity. Clinically, COPD patients exhibit significantly reduced gut microbial diversity, and the dynamic Bacteroidetes/Firmicutes ratio has emerged as a promising early diagnostic biomarker. This comprehensive review synthesizes recent five-year evidence to elucidate gut-lung axis mechanisms, identify novel microbial biomarkers for early prediction, and evaluate microbiota-targeted therapeutic interventions, ultimately providing new scientific frameworks for developing targeted strategies for COPD prevention and clinical management.",

This study demonstrates that heat-inactivated Akkermansia muciniphila AKK PROBIO significantly reduces serum uric acid levels in hyperuricemic mice (24.1\u00a0%, P\u00a0<\u00a00.05). The therapeutic effects are mediated through multiple interconnected mechanisms, including improved renal function (reduced serum creatinine and blood urea nitrogen), suppression of hepatic xanthine oxidase activity, mitigation of oxidative stress (lower malondialdehyde and higher superoxide dismutase activity), and attenuation of inflammation via inhibition of the TLR4/IKK\u03b2/NF-\u03baB pathway and NLRP3 inflammasome activation. Notably, levels of pro-inflammatory cytokines (IL-1\u03b2, IL-2, TNF-\u03b1) were downregulated, whereas anti-inflammatory cytokine IL-10 was upregulated. Furthermore, the probioctic treatment enhanced uric acid excretion by modulating key transporters (ABCG2 and GLUT9). Gut microbiota analysis revealed a restored Bacteroidota/Bacillota ratio, increased abundance of Rikenellaceae, elevated short-chain fatty acids, and reduced branched-chain fatty acids. Collectively, these findings indicate that heat-inactivated A. muciniphila AKK PROBIO may represent a promising therapeutic strategy for hyperuricemia management.",

First, RKBA effectively inhibited XOD in vitro. Then, in vivo results showed that RKBA significantly reduced serum uric acid (UA) levels, protected kidney function, and alleviated inflammation and tissue damage. Mechanistically, RKBA down-regulated XOD, ADA, and 5'-NT while modulating urate transporters URAT1, GLUT9, and OAT3, thereby rebalancing UA metabolism. Additionally, it reshaped the gut microbiome (particularly enriching Ligilactobacillus and Dubosiella) and elevated short-chain fatty acids. Subsequently, the UPLC-ESI-MS/MS-based anthocyanin-targeted omics identified and quantified 42 anthocyanins. Integrating molecular docking and dynamics simulation, pelargonidin-3,5-diglucoside was selected as the lead candidate owing to its high abundance and strong affinity for XOD.

Understanding their ecological roles can provide insights into host health and microbial community dynamics. We applied metagenome-assembled genome (MAG)-based approaches to investigate gut archaea in Tibetan antelopes (Pantholops hodgsonii) and assess their shifts in the presence of Blastocystis. A total of 463 non-redundant archaeal MAGs were reconstructed and analyzed for taxonomic diversity and functional potential. The MAGs encompassed 16,189 protein clusters, with over 70% representing potentially novel species, highlighting substantial unexplored archaeal diversity. Alpha diversity showed no significant differences between healthy and Blastocystis-present groups, but beta diversity analysis revealed marked community restructuring, including decreased Methanobacteriota and increased Halobacteriota and Thermoplasmatota in the Blastocystis-present group. Functional annotation indicated changes in energy and nucleotide metabolism and alterations in carbohydrate-active enzyme composition. Additionally, putative viral sequences were detected within archaeal MAGs, suggesting potential virus-microbe interactions.

However, the mechanisms through which 3'-SL alleviates antibiotic-associated diarrhea remain poorly understood. In this study, an antibiotic-associated diarrhea model was established through the co-administration of ampicillin and neomycin. The effects of 3'-SL supplementation on diarrhea phenotype, inflammation, intestinal permeability, and barrier function were examined in antibiotic-associated diarrhea-model mice. Moreover, gut microbiota composition, metabolite profiles, and their alterations were analyzed using genomic and metabolomic approaches. The results demonstrate that 3'-SL increased body weight and aquaporin (AQP) 3 and AQP4 levels but reduced diarrhea rate, cecal mass, and fecal water content in the model mice, indicating its therapeutic effect on diarrhea. Furthermore, 3'-SL reduced serum levels of IL-6, tumor necrosis factor (TNF)-\u03b1, and IL-1\u03b2, while increasing IL-10 levels in the mice. Moreover, 3'-SL reduced intestinal permeability by enhancing both the mechanical barrier (ZO-1 and occludin mRNA expression) and the chemical barrier (MUC2 mRNA and protein expression) in the mice. 16S rRNA analysis revealed that mice in the 3'-SL group exhibited greater abundances of Akkermansia, Bacteroides, and Dubosiella, along with a reduced relative abundance of the diarrhea-associated bacterium Alloprevotella. Furthermore, metabolomics analysis indicated that 3'-SL promoted enrichment of purine metabolism, pyrimidine metabolism, nucleotide metabolism, and the pentose phosphate pathway, which may be associated with diarrhea development, inflammation amelioration, and barrier regulation. In conclusion, our findings suggest that 3'-SL ameliorates antibiotic-associated diarrhea by modulating gut microbiota and metabolite profiles.",

Multiple studies have shown that Akkermansia muciniphila, as a promising beneficial gut bacterium, is robustly associated with positive effects on host metabolism, immunological regulation, and its presence inversely correlates with body weight. But the precise function played by this bacterium underlying lipid degradation is still unknown. Here we identify a metallophosphoesterase from A. muciniphila. The metallophosphoesterase is composed of a binuclear metal center connected with tyrosine residues and a highly conserved calcineurin-like_PHP_ApaH domain. The enzyme activity has reached its peak in the conditions of pH 8.0, temperature of 37\u202f\u00b0C. The enzyme is active for esters with short fatty-acid chains, and has high catalytic activity for hydrolysis of phospholipid sodium salts. In addition, five of predicted active sites of the metallophosphoesterase affecting its enzymatic activity are individually analyzed. Point mutation of H47 reduces the catalytic activity of the metallophosphoesterase for its most preferred substrate, while mutation of H181 has the opposite effect of increasing the enzymatic activity. Overall, we report the first characterization of AMUC-1901, a novel metallophosphoesterase from A. muciniphila with lipid degradation capabilities, which has potential for further exploration in developing novel food or pharma supplements for obesity therapies.",

However, its regulatory role on the gut-lung axis, particularly the contribution of its MXSGT components, remains unexplored. This study employed a formula-disassembled approach to decipher this mechanism. Three preparations, including the complete LHQW prescription, LHQW excluding MXSGT components (LHQW-MXSGT), and MXSGT along, were administered to LPS-induced acute lung injury and DSS-induced ulcerative colitis to evaluate their therapeutic effects via the gut-lung axis. Pathological changes, mucosal barrier integrity, inflammatory cell infiltration and pro-inflammatory cytokine levels were evaluated by H&E staining, histochemical staining, immunofluorescence, ELISA, RT-qPCR and Western blot. Metagenomic analysis (16S rDNA sequencing) was conducted to examine their regulatory role of gut microbiota. Network pharmacology analysis and cellular validation was employed to explore their underlying mechanisms. Our analyses demonstrated that LHQW and MXSGT, but not LHQW-MXSGT, significantly attenuated lung/intestinal pathology damage, reduced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), and restored gut barrier proteins (ZO-1, Occludin, MUC2). LHQW/MXSGT suppressed pathogenic bacteria (Escherichia coli, Salmonella, Klebsiella pneumoniae) while enriching Akkermansia muciniphila, correlating with decreased systemic LPS. Network pharmacology and subsequent validation identified dual inhibition of TLR4/NF-\u03baB and JAK2/STAT3 pathways as key mechanism of MXSGT. In conclusion, MXSGT serves a pivotal pharmacologically active component of LHQW for its gut-lung axis regulation, acting through gut microbiota homeostasis restoration, intestinal barrier integrity maintenance, and anti-inflammatory signaling pathways, providing compelling scientific evidence supporting LHQW's potential therapeutic application in managing diseases characterized by comorbid gut and lung inflammation.",

The composition of gut microbiota in individuals is influenced by many factors, among which gender differences are often overlooked and lack targeted treatment plans in clinical practice. Based on this, we conducted this study aimed at exploring the pathogenesis of gastrointestinal inflammation and the importance of gender specificity, providing new ideas and targets for the diagnosis and treatment of gastrointestinal inflammation stratified by gender. We collected fecal samples from 89 patients with gastrointestinal inflammation (40 males and 49 females) for DNA extraction, DNA library construction, sequencing, and clinical data analysis. In laboratory indicators, male patients had significantly lower mean LDH levels than females (P < 0.05), whereas median GGT, HB, M, and E values were significantly higher (P < 0.05). Additionally, significant differences in microbial \u03b1 diversity at the species level were observed between the two groups (all P < 0.05). In the prediction analysis of microbial population function, the mean values of heterologous biodegradation and metabolism, signal transduction, cell activity, metabolism of other amino acids, and bacterial infectious disease pathways in the female patient group were higher than those in the male patient group (all P<0.05), and the mean values of nucleotide metabolism, replication and repair, and transcription and translation were lower than those in the male patient group (all P<0.05). Gender differences affect gastrointestinal inflammation progression, with male and female patients showing distinct gut microbiota and laboratory indicators. Males have lower LDH but higher GGT, HB, M, and E, linked to hormonal effects. The gut microbiome composition differs by gender, with males having a higher prevalence of Prevotella and altered metabolic pathways. Females show higher activity in xenobiotic degradation and infection-related functions. Diet, exercise, and clinical interventions, such as FMT, can modulate the microbiota, but gender-specific responses exist. Analysis revealed significant sex-based differences in gastrointestinal disease patients, including variations in laboratory indicators (LDH, GGT, HB, M, E), gut microbiome composition and diversity, and predicted microbial functional profiles. This provides insights for precise medical treatment of gastrointestinal inflammation stratified by gender.",

This study\u00a0aims to elucidate the therapeutic mechanisms of iTBS and cTBS for ASD. METHODS: Prenatal valproic acid-induced ASD rats were established and were randomized into VPA, VPA\u2009+\u2009iTBS, and VPA\u2009+\u2009cTBS groups, with a saline group as control. Core and comorbid ASD behaviors in rats were assessed. Multi-omics analyses included 16\u00a0S rRNA sequencing of cecal contents, non-targeted fecal metabolomics, and prefrontal cortex transcriptomics. Key pathways were validated via Western blot, ELISA, and immunofluorescence. Integrative analyses correlated multi-omics data with neuroendocrine findings. RESULTS: Behavioral assessments demonstrated that both iTBS and cTBS significantly ameliorated social deficits and repetitive behaviors in VPA-exposed rats. However, protocol-specific effects on comorbidities were observed: cTBS, but not iTBS, effectively alleviated anxiety-like behaviors, whereas iTBS, but not cTBS, significantly improved learning and memory. The multi-omics approach demonstrated that iTBS primarily modulated inflammatory immune responses and energy metabolism, while cTBS predominantly regulated oxidative stress, lipid metabolism, and nucleotide metabolism. Both interventions suppressed the hyperactivated PI3K/AKT/mTOR signaling pathway, an effect potentially linked to the normalization of hypothalamic-pituitary axis function. Furthermore, we identified a potential interplay between the GH/IGF-1 axis and the gut microbiome in ASD, which was differentially modulated by iTBS and cTBS. CONCLUSION: iTBS modulated inflammatory-immune responses and energy metabolism, while cTBS regulated oxidative stress, lipid metabolism, and nucleotide metabolism. The inhibition of the central GH/PI3K/AKT/mTOR pathway by both protocols may involve their specific regulation of distinct gut microbiota communities.",

Obese asthma, as a clinical refractory asthma type, urgently needs effective and side-effect-free treatment. Xuanbai Chengqi Decoction (XBCQD) is a traditional Chinese medicine prescription widely used in the treatment of lung diseases, including asthma in China. However, the efficacy and mechanism of obese asthma remain to be explored. To elucidate the therapeutic effect of XBCQD on obese asthma and reveal its mechanism. Network pharmacology was used to predict the potential therapeutic targets and pathways of XBCQD in the treatment of obese asthma. We established a mouse model of obese asthma by feeding a high-fat diet combined with intraperitoneal injection of ovalbumin (OVA) to induce sensitization, and then intervened with intragastric administration of high, medium, and low doses of XBCQD. During the modeling period, lung function and body weight of mice were used to evaluate the preparation of the obese asthma model. H&E staining, RT-qPCR, ELISA, Western blot, and flow cytometry were used to quantify Th cell subsets, 16S rRNA sequencing was used to determine microbial composition, and GC/MS was used to detect the content of short-chain fatty acids in intestinal contents to explore the mechanism of Xuanbai Chengqi Decoction on obese asthma. Network pharmacology showed that XBCQD may improve obese asthma by affecting core targets such as IL-6, TNF, and Caspase1, and through signaling pathways such as the IL-17 signaling pathway, AGE-RAGE signaling pathway, TNF signaling pathway, and Th17 cell differentiation. Experimental studies have found that XBCQD can alleviate the symptoms of obese asthma and lung inflammation, reduce serum IgE, reduce the expression of IL-6, IL-17, and IL-23 in serum, to reduce lung inflammation induced by obese asthma in mice; flow cytometry of spleen tissue showed that XBCQD reduced the proportion of Th17 cells and restored the proportion of Treg cells. Proteomics showed that XBCQD inhibited the expression of NLRP3, Caspase-1, and IL-1\u03b2 by up-regulating the expression of GPR43, thereby inhibiting Th17-related protein ROR\u03b3t and restoring Treg-related protein Foxp3, thereby regulating immune imbalance. At the same time, XBCQD restored the intestinal microbial species, and restored the beneficial bacteria such as Dubosiella, Akkermansia_muciniphila, Rikenella, which were reduced in obese asthmatic mice, and increased the content of acetic acid, propionic acid, and butyric acid in intestinal flora metabolites. XBCQD regulates Th17/Treg immune imbalance in obese asthma by improving intestinal microecology and regulating SCFAs/GPR43/NLRP3 pathway. These findings provide new pharmacological evidence for its clinical application in obese asthma.",

This study primarily aimed to investigate the effects of daily yogurt and rolled oats consumption on gut microbial composition. Secondary outcomes included stool metabolites and blood-based health markers. In this randomized, open-label, 2-period crossover trial, 119 healthy participants were randomly assigned to 1 of 2 sequences: 250 g of yogurt daily followed by 250 g of yogurt with 50 g of rolled oats, or the reverse with a washout period in between. Stool and blood samples were collected at baseline and post intervention. Metagenomic sequencing and metabolomic analyses were conducted on stool samples, whereas health markers related to metabolic control, inflammation, immune response, oxidative stress, and gut permeability were assessed in the participants' blood. Of the 119 randomly divided participants, 110 completed the study (53 yogurt first, 57 yogurt and rolled oat first). Yogurt consumption transiently increased yogurt-associated bacteria, with Streptococcus thermophilus rising from absent to 0.97% [95% confidence interval (CI): 0.71, 1.26] in the yogurt intervention and 0.79% (95% CI: 0.58, 1.03) in the yogurt with oats intervention. In a small Prevotella-predominant subgroup (n = 8), adding rolled oats increased microbial evenness (q < 0.001) and reduced interindividual divergence (q < 0.05), suggesting a temporary slight homogenization. No additional effects on fecal short-chain fatty acids concentrations or human health markers were identified. Functional metagenomic changes were mainly driven by yogurt-derived bacterial enrichment.

Targeting the gut-kidney axis with probiotics is a promising strategy, but most candidates are food-derived and not human-adapted. We isolated two Lactiplantibacillus strains, Lactiplantibacillus pentosus JWN01 and Lactiplantibacillus plantarum JWN02, from the healthy newborn skin representing a relatively unperturbed, early-life human microbiome. In vitro, these two human-derived probiotic strains showed robust survival under simulated gastrointestinal conditions and efficiently degraded UA precursors (inosine, guanosine). In Uox-/- mice, oral supplementation with these probiotics for 12\u00a0weeks significantly reduced serum UA levels, improved renal function, and regulated key urate transporters, such as ABCG2, GLUT9, and OAT1, in kidney and ileum. The treatment also reinforced intestinal barrier integrity by upregulating tight junction proteins (Claudin-1, Occludin, ZO-1) and alleviated renal fibrosis by inhibiting the TGF-\u03b21/SMAD3 signaling pathway. Gut microbiome analysis showed that JWN01 and JWN02 administration reshaped the microbial composition by decreasing potentially harmful genera (Mammaliicoccus, Staphylococcus, Corynebacterium) and enriching beneficial taxa (Muribaculaceae, Lactiplantibacillus, Akkermansia). This microbial shift was accompanied by partial restoration of disturbed gut metabolites, including Coenzyme Q10 and p-cresol sulfate. Proteomic profiling of proximal tubules, along with subsequent validation, demonstrated that intervention with JWN01 and JWN02 suppressed pathological autophagy-evidenced by reduced ULK1, LC3A/B, and Beclin-1 expression, and increased P62 levels. Notably, the potential inflammation-related biomarkers MSP and IBA1, elevated in HN, were reversed following probiotic treatment. Together, these findings indicate that L. pentosus JWN01 and L. plantarum JWN02 confer protective effects against HN through modulation of the gut-kidney axis, supporting their potential as functional probiotics for dietary management of hyperuricemia.",

Compared with the well-studied effects of ionic copper, the chronic toxicity of CuO NPs remains largely overlooked. In this study, zebrafish were exposed to environmentally relevant concentrations (5\u00a0mg/L Cu) of CuO NPs or copper sulfate (CuSO4) to systematically evaluate intestinal toxicity induced by long-term exposure to different forms of copper. An integrated strategy incorporating ultrastructural analysis, biochemical assays, gut microbiota profiling, and metabolomic analysis was employed. Both copper forms induced mitochondrial damage, metabolic perturbations, and gut microbial dysbiosis in intestinal epithelial cells. However, CuO NPs showed markedly stronger intestinal toxicity than ionic copper. Specifically, CuO NPs can directly penetrate mitochondria in particulate form, impair mitochondrial structure, and potently activate the FDX1-LIAS-DLAT cuproptosis pathway, thereby triggering significant disturbances in amino acid, lipid, and nucleotide metabolism. Furthermore, CuO NPs exerted a more robust impact on the bidirectional gut microbiota-host metabolite interactions. In conclusion, this study clarifies form-dependent differences in copper-induced intestinal toxicity and highlights the critical role of microbiota-metabolite crosstalk in CuO NP-mediated adverse effects. These findings yield critical mechanistic insights and provide a robust scientific basis for evaluating the potential health risks posed by chronic exposure to CuO NPs.",

Probiotics and human milk oligosaccharides (HMO) are increasingly being used to address food allergies. However, the role of nonfucosylated neutral oligosaccharides in food allergies remains unclear. Moreover, HMO interact positively with probiotics, but the synergistic effects and underlying mechanisms of their combined action in alleviating food allergies remain poorly understood. Consequently, Bifidobacterium longum ssp. infantis (B. infantis), which exhibits the greatest capacity to use HMO, was chosen for this study. The effects of lacto-N-neotetraose (LNnT), B. infantis, and their combination on allergy was assessed using an ovalbumin (OVA)-induced allergic mouse model. The mechanisms underlying the alleviation of food allergies by LNnT + B. infantis were also investigated through genomics and metabolomics. The results demonstrated that LNnT and B. infantis exerted partial modulatory effects on allergic symptoms, BW, mast cell degranulation, cytokine levels, and immune cell populations in mice. Notably, the simultaneous administration of LNnT and B. infantis significantly outperformed the administration of either LNnT or B. infantis alone, indicating a synergistic effect. Furthermore, LNnT + B. infantis was found to alleviate intestinal injury. Gut microbiota analysis revealed that LNnT + B. infantis reduced the abundance of the allergy-associated bacterium Desulfovibrio and significantly increased the levels of beneficial bacteria, including Lactobacillus, Limosilactobacillus, and Blautia. The LNnT + B. infantis treatment also enhanced steroid hormone biosynthesis, ascorbate and aldarate metabolism, and nucleotide metabolism. Some substances in these pathways are produced by the gut microbiota and are linked to allergy amelioration. In conclusion, LNnT + B. infantis alleviates food allergies by modulating the gut microbiota and its associated metabolic functions in OVA mice.",

Monopterus albus whole slime (MS) is an underutilized aquatic by-product rich in proteins. This study examined the therapeutic effects and underlying mechanisms of MS and its purified protein (MSP) against cyclophosphamide (CTX)-induced immunodeficiency in mice. The results revealed that MSP significantly increased body weight, immune organ indices (spleen and thymus), cellular immune parameters (including counts of WBC, PLT, lymphocyte, and granulocyte), and humoral immune markers (including serum levels of IFN-\u03b3, IL-2, and IgA) in immunocompromised mice. Furthermore, MSP demonstrated superior efficacy compared to MS in promoting thymic recovery and enhancing IgA production (p\u00a0<\u00a00.05). Concurrently, MSP ameliorated intestinal integrity through improved villus structure, upregulation of tight junction proteins (ZO-1 and occludin), attenuation of oxidative stress (evidenced by decreased MDA level and increased SOD and GSH-Px activities), and elevated secretory IgA (SIgA) levels. Gut microbiota analysis indicated that MSP promoted the enrichment of beneficial bacterial genera (norank_f__Muribaculaceae, Muribaculum) while suppressing pathogenic bacteria (Desulfovibrio, Lachnospiraceae_UCG-006, Eubacterium_xylanophilum_group). Fecal metabolomic analysis revealed that both MS and MSP altered the profiles of various metabolites, with enriched pathways involved in nucleotide metabolism, ABC transporters, and taurine and hypotaurine metabolism. Collectively, these findings suggest that MSP may mitigate CTX-induced immunodeficiency through a potential \"gut microbiota-metabolite-intestinal barrier\" axis, thereby establishes the theoretical groundwork for the development of slime-derived proteins as potential immunomodulatory agents.",
        "41796194": "ID: 41796194\nTitle: Advanced alginate- nutriosomes for enhanced oral delivery of fermented Echium amoenum polyphenols.\nAbstract: Echium amoenum, a highly valued medicinal plant in Iran, is rich in polyphenols. Microbial fermentation can improve the bioavailability of its phenolic compounds, which are otherwise limited (5-10%), by releasing them from the plant cell wall. Moreover, incorporating these bioactive compounds in phospholipid vesicles can further maximize their biological efficacy. This study developed a combined approach using lactic acid fermentation with Lactiplantibacillus plantarum and phospholipid-based nanocarriers to optimize the delivery of E. amoenum extract. Fermented extract (50\u00a0mg/mL) was successfully incorporated into liposomes, nutriosomes, and advanced alginate-nutriosomes, as confirmed by cryo-TEM and FTIR analyses. All vesicles were nanosized (105-124\u00a0nm), negatively charged (~ -\u200956 mV), and homogeneously dispersed (PDI\u2009\u2264\u20090.19) with high loading efficiencies (>\u200990%). They remained stable under simulated saliva, gastric, and intestinal conditions and exhibited controlled release. In vitro assays demonstrated biocompatibility and protective effects on stressed Caco-2 cells. Overall, alginate-nutriosomes represent a promising nanocarrier for oral administration of fermented E. amoenum extract.",
        "41800246": "ID: 41800246\nTitle: Gut-Lung Microbiota Axis Shapes the Immune Microenvironment and Immunotherapeutic Response in Lung Cancer.\nAbstract: The gut-lung axis microbiota plays a pivotal role in shaping the tumor immune microenvironment (TIME) and regulating immunotherapeutic responses in lung cancer. This review highlights that pulmonary and gut microbial dysbiosis drives lung cancer development through inducing chronic inflammation, remodeling the immune microenvironment, and reprogramming metabolism. Lung cancer patients exhibit distinct microbial signatures characterized by altered microbiotal diversity and enrichment of specific taxa like Streptococcus, Veillonella, and Bacteroidetes in the airways, along with gut microbial shifts involving decreased Firmicutes/Bacteroidetes ratio. These microbial alterations promote tumor progression via activation of pro-inflammatory pathways (e.g., interleukin-17 (IL-17)/interleukin-23 (IL-23) axis) and suppression of antitumor immunity.Notably, the gut-lung microbiome exerts a profound impact on immunotherapeutic efficacy: responders are enriched with beneficial microbes like Akkermansia muciniphila and Bifidobacterium that enhance CD8\u207a T cell responses, while non-responders show elevated levels of Gammaproteobacteria and Fusobacterium associated with immunosuppression. Regulatory mechanisms include systemic immune modulation by microbial metabolites such as short-chain fatty acids, as well as activation of key signaling pathways including cGAS-STING and CD40L-CD40/NF-\u03baB. Emerging translational applications encompass lung cancer diagnosis and immunotherapeutic response prediction via microbial biomarkers, as well as therapeutic interventions including fecal microbiota transplantation (FMT) and probiotic supplementation. Future studies should clarify microbe-host interaction mechanisms and develop personalized microbiota-based strategies to overcome immunotherapy resistance, offering the potential to revolutionize precision oncology through integrating microbiota modulation with conventional therapies.",
        "41827072": "ID: 41827072\nTitle: Gut microbiome changes in people with diabetic retinopathy in India. DRMS-India report # 1: operational protocol and trends from first 100 participants.\nAbstract: Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus (DM), and the leading cause of vision impairment and blindness. India is among the top three countries in DM prevalence, and both DM and DR are projected to rise sharply in the future. There is no accepted strategy for the prevention of DR other than DM control. Recent studies suggest that DM is associated with alterations in a core group of gut microbiota, and progression to DR may be influenced by changes within this core group, highlighting a potential link between DR and gut microbiome. We studied these changes in a protocol-driven large case-control study, the Diabetic Retinopathy Microbiome Study-India (DRMS-India: CTRI/2024/02/062511), analysed the results of the first 100 individuals, and evaluated variations in gut microbiome in DR. The DRMS is designed to recruit 462 people aged\u2009\u2265\u200930 years into three cohorts: healthy controls (HCs), DM, and DR, at 17 independent sites in India. Shotgun metagenomic sequencing of first-pass morning fecal samples is performed at a centralized laboratory and correlated with disease status, lifestyle, dietary, and systemic factors. The first 100 participants included 26 HC, 33 DM, and 41 DR. The trends showed the DR group had 1, 6, and 10 unique core phyla, genera, and species, respectively. Alpha diversity was highest in the DR group; Beta diversity plots showed separate clusters of HCs and DR, with DM overlapping both. Firmicutes (highest in DR), Proteobacteria (highest in DM), Bacteroidetes, and Actinobacteria (highest in HC) were common phyla. Segatella was the most common genus, and Segatella copri was the most common species across all groups to date. Most microbial gene families were annotated to Molecular Functions (MF), and the pathways attributed to carbohydrate, amino acid, lipid, and nucleotide metabolism, indicating distinct functional adaptations in their gut microbiome. Trends from the first 100 individuals indicate that the gut microbiome of Indians with DR exhibits discriminatory features in microbial diversity and abundance, as well as in gene families and pathways that impact host gut metabolism. Data trends from DRMS-India indicate a region-specific non-invasive biomarker that may guide preventive therapy for DR.",

This study investigated the association between compound probiotic supplementation and the gut microbial community structure in heat-challenged broilers, analyzing the cecal contents from both groups using 16S rDNA amplicon sequencing. Compound probiotic supplementation was associated with changes in alpha diversity and richness of the cecal microbiota, with lower Shannon, Chao1, and ACE indices (p < 0.05). At the phylum level, compound probiotic supplementation significantly increased the relative abundance of Bacteroidota (p < 0.001) while decreasing that of Proteobacteria (p < 0.0001) in the cecum of broilers, whereas the relative abundances of Firmicutes and Verrucomicrobiota showed increasing trends. At the genus level, the relative abundance of Bacteroides (p < 0.0001) was significantly increased in the HP group, whereas Lactobacillus and Fusobacterium exhibited decreasing trends compared with the HS group. LEfSe analysis suggested Verrucomicrobia as a potentially enriched taxon in the HP group. Furthermore, KEGG level 3 functional prediction suggested enrichment of predicted pathways related to starch and sucrose metabolism, as well as amino acid and nucleotide metabolism in the HP group. These findings suggest that compound probiotics are associated with changes in gut microbial composition and predicted functions in heat-stressed broilers, providing preliminary, exploratory insights into their potential associations under heat stress.",
        "41836373": "ID: 41836373\nTitle: Akkermansia muciniphila primes lung-resident antiviral immunity via the gut-lung axis during SARS-CoV-2 infection.\nAbstract: The gut microbiota plays a central role in shaping systemic immunity and modulating the gut-lung axis, which is crucial during respiratory infections such as COVID-19. SARS-CoV-2 infection is known to disrupt the gut microbiome, but the downstream functional impacts on microbial metabolism and host immune responses remain insufficiently understood. Using K18-hACE2 transgenic mice, researchers investigated the effects of SARS-CoV-2 variants (WA and Omicron) on the gut microbiome and host immunity. Microbial composition and functional profiles were assessed post-infection. To test the therapeutic potential of Akkermansia muciniphila (A. muciniphila), live bacteria were administered prophylactically, and various outcomes were evaluated, including weight loss, lung pathology, immune cell phenotypes, and cytokine production. In K18-hACE2 transgenic mice infected with SARS-CoV-2, there was a marked reduction in gut microbial diversity, accompanied by a consistent enrichment of A. muciniphila. This microbial shift was associated with functional disruptions in key metabolic pathways, particularly those involved in glycosaminoglycan degradation and lipid metabolism, suggesting a broader impact of infection on microbial functionality. Remarkably, prophylactic administration of live A. muciniphila prior to infection led to significant protective effects. Treated mice exhibited reduced weight loss and improved lung histopathology compared to untreated controls. Local antiviral immune responses in the lung were notably enhanced without triggering excessive systemic inflammation. Mice receiving A. muciniphila also demonstrated elevated production of Th2 and Th17 cytokines, robust expansion of tissue-resident memory T cells, and the formation of inducible bronchus-associated lymphoid tissue (iBALT)-all indicative of potentiated mucosal immunity. These findings highlight a functional role for A. muciniphila not only as a microbial signature of COVID-19-associated dysbiosis but also as an active modulator of host immune responses during respiratory viral infections. These findings position A. muciniphila as both a biomarker of COVID-19-related gut dysbiosis and a potent live biotherapeutic candidate for respiratory infections. Its ability to enhance mucosal immune responses through gut-lung axis modulation highlights its promise in prophylactic strategies against viral respiratory diseases, including SARS-CoV-2.",
        "41851729": "ID: 41851729\nTitle: Parabacteroides goldsteinii-derived outer membrane vesicles alleviate acute lung injury via modulation of bile acid metabolism.\nAbstract: Acute respiratory distress syndrome (ARDS) is a severe clinical syndrome with limited therapeutic options. Acute lung injury (ALI) is widely used as an experimental animal model that recapitulates the key pathological features of human ARDS. Parabacteroides goldsteinii, a newly identified Gram-negative probiotic, exhibits anti-inflammatory effects in certain disease models. Gram-negative bacteria release nanoscale structures called outer membrane vesicles (OMVs), which show varying composition across species. The role of P. goldsteinii-derived OMVs (Pg-OMVs) in ALI or ARDS remains to be elucidated. In this study, we investigated the therapeutic potential of Pg-OMVs in a bleomycin (BLM)-induced ALI mouse model and explored their effects on pulmonary inflammation and gut microbiota composition. Compared to mice receiving BLM alone, Pg-OMV-treated mice exhibited significantly reduced inflammatory cell infiltration and lower levels of pro-inflammatory cytokines. Notably, Pg-OMV treatment significantly altered the gut microbiota composition, characterized by an increased abundance of Akkermansia muciniphila and a decreased abundance of Clostridia_bacterium. Fecal microbiota transplantation (FMT) experiments confirmed that the protective effects of Pg-OMVs were mediated via gut-lung axis. Further analysis revealed elevated cholic acid (CA) levels in the peripheral blood and bronchoalveolar lavage fluid following Pg-OMV treatment. CA was shown to suppress BLM-induced macrophage pyroptosis in the lung. Pharmacological inhibition of CA reversed the protective effects of Pg-OMVs, further confirming its pivotal role. In summary, Pg-OMVs increased the abundance of Akkermansia muciniphila while decreasing the abundance of Clostridia_bacterium in the gut, elevated systemic CA levels, and suppressed macrophage pyroptosis via inhibition of the NF-\u03baB pathway, thereby attenuating pulmonary inflammation and ultimately alleviating ALI. These findings highlight a novel therapeutic strategy for the treatment of ALI or ARDS by targeting the gut-lung axis.",
        "41852666": "ID: 41852666\nTitle: Microencapsulated Akkermansia muciniphila alleviates acute lung injury in juvenile mice by protecting intestinal barrier.\nAbstract: The gut-lung axis plays a critical role in the pathogenesis of acute lung injury (ALI). While intestinal microbiota, particularly Akkermansia muciniphila (AKK), has been linked to the regulation of ALI in adult murine model, its impact on juvenile hosts, who exhibit heightened susceptibility to lipopolysaccharide (LPS)-induced ALI, remains poorly understood. Moreover, despite microencapsulation enhancing the probiotic gastrointestinal survival and colonization of probiotics, the therapeutic potential of microencapsulated AKK (AKK-MC) in juvenile murine ALI has not been explored. In this study, juvenile mice were orally gavaged with live AKK or AKK-MC for 14 days, with LPS-induced ALI established on day 11. Lung tissues were analyzed for morphological changes and inflammatory cytokine analysis. Bronchoalveolar lavage fluid (BALF) was collected for total cell counts and protein concentration. Macrophages and neutrophils infiltration in the lungs was quantified via immunofluorescence staining. Four segments of the intestinal tract (jejunum, ileum, cecum, and colon) were harvested for histological analysis using hematoxylin and eosin (H&E), Alcian blue-periodic acid-Schiff (AB-PAS), and toluidine blue (TBO) staining. These evaluations included measurements of villus height to crypt depth, intestinal injury scoring, and counts of goblet and mast cells. AKK-MC treatment resulted in higher fecal abundance of AKK compared to AKK group. AKK treatment attenuated LPS-induced weight loss and mitigated lung damage. This was evidenced by reduced protein concentration and cell counts in BALF, downregulation of Tnf-\u03b1 and Il-1\u03b2 expression, improved lung histology, and decreased macrophage infiltration and neutrophil extracellular traps formation. In the intestine, AKK treatment restored mucosal architecture, increased villus height to crypt depth ratios, maintained goblet cell populations, and reduced mast cell infiltration across intestinal segments. These results demonstrate that microencapsulation enhances AKK's efficacy in ameliorating LPS-induced ALI in juvenile mice through gut microbiota modulation. This study provides a crucial foundation for the development of probiotic-based interventions in pediatric ALI.",
        "41874370": "ID: 41874370\nTitle: Gut microbiota impact on lung diseases: a mini review of clinical evidence.\nAbstract: The gut-lung axis represents a bidirectional communication network through which the gut microbiota (GM) influences respiratory health. This mini-review synthesizes clinical evidence on the role of the GM in lung diseases. We focused exclusively on human clinical trials, randomized controlled trials, meta-analyses, and systematic reviews, sourced from major databases after duplicate removal. The evidence indicates that GM dysbiosis is a significant risk factor for the susceptibility and severity of various respiratory conditions, including asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and infections, such as COVID-19 and pneumonia. Specific microbial signatures and metabolic profiles, particularly involving short-chain fatty acids (SCFAs), are associated with disease states and outcomes. Interventions like probiotics, prebiotics, synbiotics, and fecal microbiota transplantation (FMT) show promise in modulating the GM and improving clinical parameters, though their efficacy can be inconsistent and influenced by confounding factors. In conclusion, the GM is a promising therapeutic target for lung diseases. However, future research must prioritize large-scale, longitudinal clinical trials and deeper mechanistic investigations to establish causality and develop effective, personalized microbiome-based therapies.",
        "41876882": "ID: 41876882\nTitle: Revolutionizing sweetness: the multifaceted health benefits of fermented stevia.\nAbstract: Stevia rebaudiana is widely recognized as a natural, zero-calorie sweetener. However, recent evidence suggests that microbial fermentation can profoundly transform its biochemical profile, unlocking health benefits that extend far beyond sweetness. This review systematically compares unfermented versus fermented stevia extract based on biochemistry, health consequences, technology, and safety. It aims to critically evaluate the evidence demonstrating how fermentation enhances the bioavailability, bioefficacy, and functional characteristics of stevia, thereby facilitating its transition from a simple sweetener to a multifunctional food ingredient. The investigation shows that the phytochemical composition of stevia is dramatically changed by fermentation. Microbial agents such as yeast and lactic acid bacteria facilitate fermentation, which changes steviol glycosides, produces new bioactive metabolites (such as terpenoids), and increases the amount of healthy chemicals. Consequently, fermented stevia extract exhibits improved antioxidant, antibacterial, antidiabetic, and anticancer activity in vitro and in animal models. A key differentiator is its potent ability to modulate gut microbiota, effectively alleviating dysbiosis and reducing associated inflammatory markers. Furthermore, fermentation improves the sensory profile of stevia extract and facilitates its seamless incorporation into diverse food matrices, such as dairy products and beverages, without compromising sensory quality. Beyond its inherent sweetening function, fermentation transforms stevia extract and unleashes health advantages, as the evidence clearly shows. Because of its higher bioactivity and capacity to alter gut flora, fermented stevia extract is a viable functional ingredient for the food and nutraceutical industries. Future research must, however, close the existing knowledge gaps in order to realize its full potential. These gaps include the need for more elucidation of the mechanisms of action, standardization of production processes, and longer-term human clinical trials to confirm safety and efficacy. Addressing these challenges will firmly establish fermented stevia extract as a key component in the next generation of health-focused products. KEY POINTS: \u2219\u00a0Fermentation increases the bioactivity of stevia extract and its gut health advantages. \u2219\u00a0It turns stevia extract into a sensory-enhanced, multipurpose culinary component. \u2219Mechanism studies, process standardization, and human testing are all future needs.",
        "41877093": "ID: 41877093\nTitle: The red cell distribution width-to-albumin ratio mediates the association between the dietary index for gut microbiota and chronic obstructive pulmonary disease.\nAbstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major global health burden, with emerging evidence implicating gut microbiota dysbiosis via the gut-lung axis. The Dietary Index for Gut Microbiota (DI-GM) quantifies dietary impact on microbial health, but the mechanisms linking DI-GM to COPD risk remain unclear. This study aimed to investigate whether systemic inflammatory-nutritional biomarkers might explain the association between DI-GM and COPD, with a focus on the red cell distribution width-to-albumin ratio (RAR). METHODS: This cross-sectional analysis included 20,487 U.S. adults aged\u2009\u2265\u200940 years from the National Health and Nutrition Examination Survey (2005\u20132018). DI-GM was derived from 24-hour dietary recalls, and COPD was defined by self-reported physician diagnosis. Survey-weighted multivariable logistic regression and mediation analysis were used to assess associations and statistically decompose the potential mediating effects of 11 inflammatory-nutritional biomarkers. RESULTS: Each one-unit increase in DI-GM was associated with an 8% reduction in COPD prevalence (odds ratio 0.92, 95% confidence interval 0.88\u20130.97). In the mediation analysis, RAR was the most robust factor, accounting for 10.3% of the observed total association. Other biomarkers, including the neutrophil percentage-to-albumin ratio and monocyte-to-albumin ratio, showed significant but weaker contributions. These findings were consistent in sensitivity analyses. CONCLUSIONS: Adherence to a gut microbiota-beneficial diet is associated with reduced COPD risk, and this association may be partially explained by systemic inflammatory-nutritional status. RAR emerged as a significant intermediary factor in this observed association, providing epidemiological clues for the gut-lung axis and suggesting its potential as a biomarker for further investigation in targeted prevention strategies.",

This study investigated whether dietary fiber intake differs between COPD patients and healthy controls, and examined its association with systemic inflammation and lung function. A case-control study was conducted including 100 COPD patients (cases) and 100 age- and sex-matched healthy controls. Dietary fiber intake was assessed using a validated food frequency questionnaire. Systemic inflammatory markers (CRP, IL-6) were measured by ELISA. Lung function parameters (FEV1, FEV1/FVC, DLCO) were evaluated according to ATS/ERS guidelines. Logistic regression analysis was performed to assess the association between dietary fiber intake and COPD risk. COPD patients had significantly lower dietary fiber intake (18.30 \u00b1 6.20 g/day) compared to controls (28.70 \u00b1 8.10 g/day, P < 0.001). Inflammatory markers were significantly elevated in COPD patients: CRP (5.80 \u00b1 3.20 vs. 1.20 \u00b1 0.80 mg/L), IL-6 (8.40 \u00b1 4.10 vs. 2.10 \u00b1 1.30 pg/mL) (all P < 0.001). In COPD patients, dietary fiber intake was inversely correlated with CRP (r = -0.52), IL-6 (r = -0.48), and positively correlated with FEV1 (r = 0.41) and DLCO (r = 0.38) (all P < 0.001). After adjusting for confounders, low dietary fiber intake (<20 g/day) was associated with 3.2-fold increased odds of COPD (OR = 3.24, 95% CI: 1.86-5.65, P < 0.001). Low dietary fiber intake is significantly associated with COPD and correlates with increased systemic inflammation and reduced lung function. These findings support the potential role of the gut-lung axis in COPD pathophysiology. However, causality cannot be established due to the limitations of the cross-sectional case-control design. Prospective interventional studies are warranted to confirm these associations and evaluate whether dietary fiber modification can improve clinical outcomes in COPD patients.",

We aimed to verify whether gut microbiota composition is associated with cellular, metabolic, and immune pathways in atopic dermatitis. Fifty adults with atopic dermatitis and 25 sex- and age-matched healthy controls were enrolled. Gut microbiome composition was assessed using V3-V4 16S rRNA sequencing. Functional pathways were inferred from microbiome data using PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States). Despite only subtle differences in microbiota composition between patients with atopic dermatitis and controls, PICRUSt analysis identified significant differences in 149 functional pathways. Key pathways enriched in atopic dermatitis involved signal transduction mediated by protein kinases, as well as carbohydrate and lipid metabolism. Downregulated pathways included those related to energy metabolism, amino acid and nucleotide metabolism, antigen processing, and innate immune responses. In patients with atopic dermatitis, microbial diversity increased with EASI scores and IgE levels, correlating with additional predicted functional shifts. Our results suggest that even subtle structural differences in gut microbiota may exert significant functional effects in atopic dermatitis. Altered pathways could contribute to immune imbalance and impaired epidermal barrier function. These findings underscore the importance of incorporating functional analyses into future gut microbiota studies of atopic dermatitis to help identify therapeutic targets, including candidate probiotic strains for supplementation. Bacteria living in the gut, known as the gut microbiome, may play a role in the development of certain diseases. Changes in the diversity and composition of the gut microbiome have been linked to atopic dermatitis, a skin condition that causes itchy lesions and greatly affects quality of life. However, few studies have examined how gut bacteria may influence metabolism and immune responses in people with atopic dermatitis. In our study, we analyzed the gut microbiome of 50 adults with atopic dermatitis and 25\u00a0healthy individuals using sequencing methods and a software tool called PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States). Despite only subtle differences of microbiome composition between the groups, PICRUSt predicted changes in many metabolic, cellular, and immune-related pathways. These included carbohydrate, lipid, and amino acid metabolism, innate immune responses, and signal transduction pathways that may contribute to inflammation and skin barrier problems seen in atopic dermatitis. Our findings suggest that even when overall microbiome diversity appears similar, subtle changes in gut bacteria may still have important effects on metabolism and immune function. Future studies should combine microbiome and metabolic analyses to confirm these results and may help guide targeted treatments, such as probiotic supplementation.",

Recent evidence suggests that lifestyle diseases and viral infections further exacerbate OSA severity through common inflammatory and metabolic pathways. Parallelly, gut dysbiosis has gained recognition as a key mediator which links respiratory, metabolic, and infectious disease processes via the gut-lung axis. This review explores the convergent role of gut microbial dysbiosis across OSA, lifestyle-associated comorbidities such as obesity, diabetes, and cardiovascular disease and viral infections including respiratory syncytial virus (RSV), influenza, dengue, Human Immunodeficiency Virus (HIV), and SARS-CoV-2. Across these conditions, a recurring pattern of reduced beneficial commensals (e.g., Bifidobacterium, Faecalibacterium prausnitzii, Roseburia, Akkermansia muciniphila) and a noted increase of pro-inflammatory taxa (e.g., Escherichia, Streptococcus, Enterobacteriaceae) has been observed. It contributes to epithelial barrier breakdown, endotoxemia, metabolic dysfunction, and immune dysregulation. In OSA patients, intermittent hypoxia is observed that causes gut barrier impairment and microbial translocation, thus amplifying systemic inflammation. Similarly, viral infections reshape the gut ecology, bringing adverse effects to host immunity and respiratory outcomes. The review highlights upon the therapeutic potentials of prebiotics and probiotics supplementation for modulating gut dysbiosis. It discusses the role of these therapeutic interventions in improving metabolic homeostasis, reducing inflammation, and potentially mitigating OSA-related complications. Collectively, this analysis highlights gut dysbiosis as a plausible unifying mechanism connecting lifestyle diseases, viral infections, and OSA, presenting a compelling avenue for integrated, microbiome-targeted interventions.",
        "41895991": "ID: 41895991\nTitle: Effect of processing on the protein digestibility and mineral bioavailability of legumes.\nAbstract: This study evaluates how processing methods, soaking/cooking, fermentation (e.g. tempeh), and protein coagulation (e.g. tofu), affect the nutritional profile, protein digestibility, and mineral bioavailability of faba beans, grey peas, yellow peas, and soybeans. Protein digestibility was assessed using in vitro digestion and o-phthalaldehyde (OPA) assay, whilst mineral bioavailability was estimated using phytate-to-mineral molar ratios and further evaluated using a Caco-2/HT29-MTX co-culture model measuring ferritin formation. Processing markedly influenced nutritional properties. Protein coagulation resulted in the highest protein content and degree of hydrolysis, indicating improved protein digestibility. Fermentation substantially reduced phytate levels across all crops, in some cases below detection limits, leading to lower phytate-to-mineral ratios compared with cooked and tofu products. Consistent with these estimates, higher ferritin formation was observed in cells exposed to digested fermented products than to tofu digesta. Processing also altered amino acid composition, reflecting structural modifications of proteins. Overall, the results demonstrate that processing modulates protein digestibility and mineral bioavailability of legumes. Fermentation shows potential to enhance mineral availability, whereas protein coagulation improves protein digestibility. These findings are based on in vitro and cell-based models and provide guidance for the development of nutritionally improved plant-based foods.",

However, the underlying mechanisms linking MASLD to colorectal adenoma remain unclear, and the role of gut microbiota and metabolites in this association requires further investigation. This study aims to characterise the gut microbiota and metabolites in patients with MASLD and colorectal adenoma. A cohort of 58 MASLD patients was enrolled and stratified into two groups based on colorectal adenoma status: the MASLD with colorectal adenoma group (M-CA group, n\u2009=\u200930) and the MASLD without colorectal adenoma group (M-NCA group, n\u2009=\u200928). The gut microbial ecosystem in the M-CA group showed significant dysregulation, evidenced by a decreased Gut Microbiome Health Index (GMHI) and significantly increased Microbiome Dysbiosis Index (MDI). Linear Discriminant Analysis Effect Size (LEfSe) identified 75 differentially abundant microbial taxa between groups, with Bacteroides vulgatus, Bacteroides ovatus, uncultured bacterium of norank genus of Muribaculaceae family, Muribaculaceae, and norank of Muribaculaceae family being significantly enriched in the M-CA group, representing potential microbial biomarkers for this cohort. Partial Least Squares Discriminant Analysis (PLS-DA) screened 116 differential metabolites. When combined with Random Forest (RF), Support Vector Machine (SVM) and Least Absolute Shrinkage and Selection Operator (LASSO) machine learning algorithms, 16 significantly identified biomarkers were discovered. The joint analysis of both omics revealed that variations in differential metabolite levels were associated with changes in specific microbiota abundances. Kyoto encyclopedia of genes and genomes (KEGG) functional prediction analysis indicated that the coordinated alterations in metabolites and microbiota may collectively influence multiple metabolic pathways, including lipid metabolism, xenobiotics biodegradation and metabolism, amino acid metabolism, carbohydrate metabolism, biosynthesis of other secondary metabolites and nucleotide metabolism. This study revealed that patients with MASLD and colorectal adenoma exhibited significant alterations in the gut microbiota composition and metabolic profile, indicating potential impacts on associated metabolic pathways. These findings provided novel insights and a foundation for future research into potential intervention strategies for this clinical complication.",

Soybeans germinated for 0-3\u00a0days were fermented, with their rheology, microstructure, intermolecular interactions, and in vitro digestion analyzed. Germination weakened gel viscoelasticity, increased pore size, and shifted the dominant forces from hydrogen bonds to hydrophobic interactions. This is likely due to the higher endogenous proteases and 7S/11S ratio. Germination-derived gels (especially 2-3\u00a0days) disintegrated faster in the stomach, released more soluble protein in the intestine, and produced more peptides. Peptidomic analysis revealed that 2-day germination (fermented soft gel, FSG) yielded the most bioactive peptides via targeted subunit degradation, while 3-day germination (fermented ultrasoft gel, FUG) caused over-hydrolysis, leading to loss of specific bioactive motifs. These findings demonstrate that controlled germination time (2-day) optimizes LAB-fermented gel structure to improve digestive efficiency and bioactive peptide release, providing a novel strategy for designing plant-based dairy.",

Metagenomic approaches have substantially advanced understanding of these interactions by enabling comprehensive profiling of respiratory and gut-associated microbiomes and their functional potential. Evidence indicates that asthma is frequently associated with early-life microbial perturbations, reduced community diversity, enrichment of Streptococcus, Moraxella, and allergen-associated fungi, and gut dysbiosis that influences immune maturation and tolerance. In contrast, COPD is characterized by adult-onset dysbiosis with Proteobacteria dominance, depletion of commensal anaerobes such as Prevotella and Veillonella, and functional signatures linked to chronic inflammation, xenobiotic metabolism, and exacerbation risk. Across both diseases, alterations in gut microbial composition and metabolite profiles, including short-chain fatty acids, highlight the gut-lung axis as a key regulatory interface shaping airway immune responses. Despite these advances, critical knowledge gaps remain, including limited longitudinal data, incomplete multi-kingdom analyses, and insufficient mechanistic and translational validation of disease-associated microbiome signatures. This review integrates current metagenomic evidence to delineate disease-specific and shared microbial patterns, examines host-microbe interaction pathways within molecular and clinical contexts, and critically evaluates the implications and limitations of microbiome-based interventions. By framing microbiome research within a systems biology and public health perspective, this article underscores the importance of context-dependent interpretation and identifies priorities for future longitudinal, mechanistic, and translational studies in OLDs.",

The pharmaceutical industry has leveraged the capacity of medium-chain fatty acids and their derivatives to transiently and reversibly open epithelial TJs in formulations to enable oral administration of therapeutic peptides, some of which have received regulatory approval or are progressing in advanced clinical trials. Other food-derived agent including chitosan and its analogues enhance mucoadhesion and also modulate TJ permeability in the intestine. Recently, pelargonidin, a polyphenolic pigment isolated from strawberries, has emerged as a promising food-derived TJ opener, facilitating oral insulin delivery in rat models. Conversely, other food or food-derived molecules reinforce TJ integrity while exerting antioxidant effects, thereby offering potential therapeutic benefits for conditions characterized by increased intestinal permeability including inflammatory bowel disease, sepsis, and coeliac disease. Examples of such agents include the short-chain fatty acid (SCFA), sodium butyrate, various essential and non-essential amino acids, fermented food, the trace element, zinc, and anthocyanins. The exploration of food-derived substances as modulators of intestinal epithelial TJ dynamics is still in its early stages but holds significant promise for future health applications.",

Silicosis is a subtype of PF that is specifically caused by the inhalation of crystalline silica particles. In recent years, the gut-lung axis has been shown to be involved in the occurrence and progression of various respiratory diseases. However, the involvement and specific mechanism of action of the gut microbiome in silica-induced PF remain to be elucidated. Therefore, we established a silica-induced PF murine model using an inhalation exposure system, and combined gut metagenomic and untargeted metabolomics data to correlate microbial and metabolic changes with profibrotic cytokine levels. In mice exposed to silica dust for 64 days and 128 days, Akkermansia muciniphila and Staphylococcus lentus were significantly enriched, whereas the abundance of Lactobacillus murinus was notably reduced. Relevant network analysis revealed that these gut microbiota changes were highly correlated with metabolic disorders of tryptophan and arginine. Moreover, changes in the gut microbiome composition corresponded with the fluctuations in the levels of profibrotic cytokines, including transforming growth factor-beta, tumor necrosis factor-alpha, fibroblast growth factor, and hydroxyproline. We successfully established a murine model of PF induced by silica inhalation. Our results suggest that Lactobacillus murinus, Akkermansia muciniphila, and Staphylococcus lentus are key microorganisms involved in the development of silica-induced PF, while the arginine and tryptophan metabolic pathways serve as key regulatory pathways in the gut-lung axis contributing to disease development.",

XA511 in tumor microenvironments.\nAbstract: Growing evidence suggests that the gut microbiome and specific gut microbes influence carcinogenesis both within the gastrointestinal tract and in distant organs through immune, metabolic, and inflammatory pathways. Megasphaera elsdenii, a gram-negative-staining, strictly anaerobic member of the Veillonellaceae family, has been implicated in disruption of colonic epithelial homeostasis and may exert systemic effects beyond the intestine. While much attention has focused on the gut-brain axis, this mini-review synthesizes current evidence linking intestinal dysbiosis, microbial metabolite signaling, and immune crosstalk along the gut-lung axis. By integrating findings from studies on microbial translocation, mucosal immunity, and metabolite-mediated inflammation, we present a hypothesis-generating model in which M. elsdenii-driven gut dysbiosis may shape lung cancer pathogenesis through short-chain fatty acid-dependent immunometabolic signaling and hypothesized lymphatic and outer membrane vesicle-mediated pathways, recognizing that existing lung data derive solely from non-causal, genus-level 16S rRNA surveys. We further distinguish viable colonization from detection of immunogenic DNA and vesicular debris in distal tissues and discuss the context-dependent roles of the genus, contrasting the systemic pathogenicity of M. elsdenii in the gut-lung axis with the divergent, protective metabolic profile of a distinct gut-derived strain, Megasphaera sp. XA511, in pancreatic tumor microenvironments. This framework highlights Megasphaera as an understudied but potentially actionable modulator of cancer immunobiology.",

Its biological activities, including modulating immune responses and alleviating oxidative stress, make it a promising therapeutic candidate for inflammatory diseases. However, the precise role of this compound in mitigatingEscherichia coli induced (E. coli-induced) intestinal inflammation remains largely unexplored. More specifically, the mechanistic underpinnings by which it preserves intestinal mucosal barrier integrity, fine-tunes the activation dynamics of key mediators in intestinal inflammatory signaling cascades, and orchestrates the intricate crosstalk between intestinal microbiota homeostasis and host immune responses remain poorly elucidated. In this study, a total of 144 three-week-old specific pathogen-free (SPF) chickens were randomly divided into groups. An E. coli-induced enteritis model was subsequently established in these animals. Luteolin was administered at varying doses through the feed for a period of one week. The potential protective effects of luteolin against E. coli-induced intestinal damage were investigated from multiple aspects, including intestinal barriers function, gut microbiota composition, and differential metabolites profiles. Luteolin alleviated intestinal damage, enhanced survival rate and weight gain in chicken (P<0.05) and improved antioxidant capacity by reducing oxidative stress (P<0.05). It repaired intestinal barrier injury by upregulating the mRNA levels of tight junction proteins, and reduced intestinal inflammation by inhibiting the activation of the Toll-like receptor 4 nuclear (TLR4)/Myeloid Differentiation Primary Response Protein 88 (MyD88)/factor-\u03baB (NF-\u03baB) signaling pathway (P<0.05). In addition, luteolin reversed E. coli-induced gut microbiota dysbiosis, increasing the abundance of beneficial microorganisms such as Lachnospiraceae-Clostridium and Butyricimonas. Metabolomics analysis further revealed that luteolin partially corrected E. coli-induced metabolic disorders by modulating nucleotide metabolism (IMP, P<0.05), amino acid biosynthesis(arginine ornithine and lysine, P<0.05), and glutathione metabolism (S - lactoyl glutathione, P<0.05). Notably, a significant association was observed between gut microbiota and metabolic products (P<0.05). In summary, luteolin alleviates E. coli-induced enteritis in chickens via a multi-target mode of action that entails preserving gut microbiota homeostasis, restoring intestinal metabolic signatures, and suppressing the TLR4/MyD88/NF-\u03baB signaling cascade, which offers new perspectives for avian disease management and highlights its prospects as a safe antibiotic substitute.",

The gut-lung axis and microbial metabolites, such as short-chain fatty acids (SCFAs), have emerged as modulators of lung inflammation. We investigated the therapeutic effects of Lactobacillus fermentum HEM20792 (LF), identified through a colon mimetic personalized pharmaceutical meta-analytical screening (PMAS) platform using fecal samples from severe COPD patients. LF and Lactobacillus sakei HEM20224 (LS) were orally administered to smoke-exposed mice, followed by lung function testing, histopathology, RNA sequencing, single-cell transcriptomics, and fecal microbiome/SCFAs analyses. LF attenuated emphysematous changes, improved compliance, and reduced macrophage and IL-17+ lymphocyte infiltration. Single-cell analysis showed restoration of alveolar macrophages and reduction of pathogenic C1q+ macrophages, while transcriptomics revealed normalization of NF-\u03baB and arachidonic acid pathways and attenuation of IL-17- and SPP1-associated signaling. LF also increased fecal SCFAs levels. These findings provide preclinical evidence for LF as a promising microbiome-based therapeutic candidate for COPD.",

There is increasing interest around the health effects of individual nutrients versus whole foods, creating a need to better understand how the matrix may influence health outcomes. This narrative review explores the dairy milk matrix and compares health effects with those of isolated components, with additional comparisons to plant-based milk alternatives. Comparative evidence suggests that while calcium from food and supplements generally has similar effects (depending on the form of the supplemental calcium), consumption of food-based sources such as milk may have fewer adverse effects associated with high-dose supplemental intake. Fermented milk products appear to offer additional health benefits compared with unfermented milk, likely due to bioactive compounds produced during fermentation. Structural and functional manipulation of milk proteins, such as whey and lactoferrin, can also modify matrix functionality; for example, appropriate processing conditions can preserve lactoferrin's iron-binding capacity, supporting iron transport and bioavailability. Compared with plant-based milks, which often require fortification and extensive processing, the dairy milk matrix is particularly effective at promoting nutrient absorption. Our findings highlight the importance of adopting a whole food perspective when considering milk in dietary recommendations and research.",

Fermentation improves the nutritional quality, digestibility, shelf life, and sensory attributes of plant-based foods. Finger millet (Eleusine coracana) and soybean (Glycine max) are promising for functional food development due to their complementary nutrient profiles. Finger millet is rich in minerals, fibre, and polyphenols, while soybean provides high-quality protein and bioactive compounds. Their synergistic amino acid profiles and the benefits of fermentation-such as improved micronutrient bioavailability and reduced antinutritional factors-make them suitable for developing innovative fermented foods. Therefore, this review evaluates the nutritional value, fermentation potential, and health-promoting properties of finger millet and soybean for sustainable nutrition and food security. A narrative review following PRISMA principles was conducted using Google Scholar, PubMed, ScienceDirect, and Scopus. Literature from 2000-2025 on finger millet, soybean, fermentation, and functional foods was searched, yielding 116 records. After screening, 59 peer-reviewed studies were included. Two reviewers independently extracted and analysed data through thematic synthesis on nutritional composition, fermentation methods, microbial ecology, functional properties, and health benefits. The literature shows that fermentation significantly enhances the nutritional and functional value of both crops. Fermentation reduces antinutritional factors such as phytates and tannins, improves protein digestibility, and increases mineral bioavailability. Lactic and acetic acid fermentation also enhance flavour, texture, and shelf stability. However, the review identified a major research gap: few documented fermented foods combine finger millet and soybean despite their complementary nutritional profiles. Finger millet and soybean present strong potential for developing next generation fermented functional foods that address malnutrition, lactose intolerance, and dietary protein deficiencies. Nevertheless, several challenges remain, including fermentation standardization, sensory acceptance, limited infrastructure, and insufficient characterization of microbial communities and bioactive metabolites. Advancing multi-omics research, improving fermentation technologies, and promoting supportive policies and value chains will be critical for translating these crops into scalable, sustainable food innovations.",

Among these, soymilk fermentation by lactic acid bacteria emerges as a captivating opportunity to produce enhanced soy-based flavor profiles with extended nutritional value. Among the numerous advantages, components of soymilk, such as isoflavone aglycones and peptides, show a hypolipidemic effect, thus proving beneficial to humans. Of central interest is Lactobacillus, a well-studied probiotic genus that exerts a pivotal role in the maintenance of gut barrier and microbial diversity. The interplay between gut microbiome and host physiology underscores its role in health and disease. Gut dysbiosis results from the interaction of environmental cues with host metabolic state, triggering pathological consequences. These range from irritable bowel syndrome and gastric cancer to neurological disorders. This review attempts to evaluate the knowledge surrounding fermented soymilk to shed light on the vital role of Lactobacillus in restoring a dysbiotic state within the gut microbiome. Further, we elucidate multifaceted mechanisms underlying the therapeutic potential of Lactobacillus-fermented soymilk. By exploring this complex interplay of microbial metabolites and host immune responses, and incorporating recent advancements in probiotic therapeutics, we emphasize the utilization of Lactobacillus-fermented soymilk as a dietary intervention to promote gut health and alleviate disease states.",

Forty-two patients with gastrointestinal symptoms were recruited and assigned to group A (Hp+ SIBO+), B (Hp+ SIBO-), C (Hp- SIBO+), or D (Hp- SIBO-) based on their Hp infection and SIBO status. Fecal samples were collected for metagenomic sequencing and untargeted metabolomic analysis. The associations between microbiota and metabolites were evaluated using alpha/beta diversity analysis, differential species screening, metabolite identification, and Procrustes/Spearman correlation analysis. Neither Hp infection nor SIBO significantly altered the alpha or beta diversity of the gut microbiota (both P > 0.05). However, specific shifts in microbial abundance were observed. Specifically, the abundance of short-chain fatty acid-producing bacteria such as Megamonas was significantly decreased in the SIBO+ groups. Metabolomic analysis revealed significant enrichment of inflammatory metabolites (e.g., prostaglandin derivatives) in group A, disordered bile acid conjugates (e.g., chenodeoxycholylisoleucine) and nucleotide metabolism in SIBO+ groups, and abnormal lipid/carbohydrate metabolism pathways in Hp+ groups. Multi-omics integration analysis indicated a strong coupling between the microbial structure and metabolic profiles (Procrustes analysis, P < 0.05). In group A, the abundance of Faecalibacterium and Hominenteromicrobium was negatively correlated with bile acid levels, suggesting impaired bile acid transformation. Hp infection and SIBO might synergistically exacerbate gut ecological and metabolic disorders by reshaping specific microbiota and metabolic networks (enhanced inflammatory response, disrupted bile acid circulation). Their co-occurrence produces additive effects, which could explain the aggravated clinical symptoms. This study provides a theoretical basis for interventions targeting microbiota-metabolite interactions, such as probiotics and bile acid modulators.",

Although electroacupuncture (EA) demonstrates therapeutic potential in COPD, its mechanisms in modulating the gut-lung axis to alleviate inflammation and EMT remain unclear. In cigarette smoke and lipopolysaccharide (LPS)-induced COPD rats, we evaluated lung function, airway collagen deposition, pro-inflammatory and anti-inflammatory cytokines in serum, bronchoalveolar lavage fluid (BALF), and colon tissue, EMT markers in lung tissue, serum LPS levels, and 16S rRNA sequencing of lung and gut microbiota. Interventions comprised authentic EA at bilateral \"Feishu\" (BL13) and \"Zusanli\" (ST36) acupoints versus sham acupuncture at non-acupoint. Electroacupuncture significantly attenuated airway remodeling, as evidenced by improved lung function and reduced collagen deposition. EA modulated gut-lung microbiota by suppressing pro-inflammatory pathogens and enriching immunoregulatory taxa. These changes correlated with reduced serum endotoxemia and inflammation, marked by decreased pro-inflammatory cytokines and increased IL-10 in serum, BALF, and colon tissues. The ameliorated inflammatory environment was further linked to inhibition of EMT in airways, shown by upregulated epithelial markers and downregulated mesenchymal markers. Correlative analyses supported these associations. Ligilactobacillus enrichment negatively correlated with serum LPS, while Mycoplasmopsis positively associated with inflammation and EMT markers. Sham acupuncture failed to achieve these effects. Electroacupuncture ameliorates airway remodeling in COPD by modulating gut and lung microbiotareducing inflammation and inhibits EMT, suggesting microbiota regulation as a potential contributor to its therapeutic effects.",

The gut-lung axis has emerged as a pivotal paradigm for understanding this systemic nature, underscoring the regulatory potency of gut microbiota-derived metabolites in inter-organ immune and metabolic crosstalk. Accumulating evidence suggests that COPD is intricately linked to gut microbiota dysbiosis and widespread disturbances in bioactive metabolites, particularly short-chain fatty acids (SCFAs), tryptophan-related amino acids (AAs), and bile acids (BAs). These metabolic aberrations exacerbate pulmonary inflammation by dysregulating immune homeostasis, compromising intestinal barrier integrity, and skewing redox balance. Fecal microbiota transplantation (FMT), as a strategy capable of comprehensively reconstituting gut microbial and metabolic homeostasis, has demonstrated potential in preclinical and translational settings to attenuate pulmonary injury via the gut-lung axis. This review centers on gut microbiota-associated metabolites, systematically summarizing their roles in COPD pathogenesis and critically evaluating the emerging evidence and mechanistic basis by which FMT recalibrates COPD progression through metabolic pathways, thereby providing a robust theoretical framework for developing precision gut microbiota-targeted systemic therapeutic strategies.",

Among six SAs tested, isomalt, erythritol, xylitol and sorbitol significantly lowered fasting serum insulin and hepatic lipid levels in healthy rats, while mannitol and maltitol showed no such effect. Moreover, isomalt consumption lowered body weight gain, low-density lipoprotein and tumor necrosis factor-\u03b1, while improving high-density lipoprotein concentrations. All SAs effectively regulated gut microbiota composition and functionality. Most of the microbiota enriched by isomalt were short-chain fatty acid producers, including Faecalibaculum, Bacillus, Dubosiella and Anaerostipes, which led to a significant increase in the propionate proportion in faeces. The elevated Blautia and UCG-008 and lowered Akkermansia were the key specific responders to sorbitol, mannitol and maltitol. Notably, almost all SAs showed inhibitive efficacy on opportunistic pathogens such as Streptococcus, Staphylococcus and Ruminococcus. Dietary SAs significantly shifted stool and global metabolome profiles in rats. Isomalt and maltitol activated aldosterone-regulated sodium reabsorption and suppressed steroid hormone biosynthesis. Isomalt and sorbitol induced the thyroid hormone signaling pathway. Erythritol intake expressively triggered histamine metabolism, chemical carcinogenesis-receptor activation and folate biosynthesis. Xylitol, sorbitol and mannitol robustly promoted nucleotide metabolism, lysine biosynthesis and pyrimidine metabolism. Sorbitol and mannitol administration induced arginine biosynthesis, nicotinate and nicotinamide metabolism and terpenoid backbone biosynthesis. Additionally, stool metabolome suggested that mannitol intake attenuated ferroptosis in rats. Interestingly, structurally similar SAs, e.g. sorbitol, mannitol and maltitol, showed more shared microbiota and metabolites. This systematic comparative study identifies specific microbiota and associated metabolic pathways as responders to each SA and provides novel insights for future application in functional foods.",

Astragalus membranaceus shows promise for DN, and microbial fermentation enhances herbal bioavailability and efficacy. This study compared fermented A. membranaceus broth (FA) and its aqueous extract (EA) in streptozotocin-induced DN rats, with 8-week low/medium/high-dose treatment. FA outperformed EA in improving metabolic parameters and renal function: superior body weight recovery, greater reductions in fasting blood glucose, serum BUN, ALT, and TG, enhanced renal antioxidant capacity (elevated SOD/GSH-Px and reduced MDA), and alleviated glomerular/tubular injury and interstitial inflammation. Chemical profiling identified 14 FA bioactive components; network pharmacology revealed core targets (STAT3, IL6, and TGFB1) and key pathways (AGE-RAGE, HIF-1, and FoxO). Fermentation boosts A. membranaceus efficacy in DN via better active constituent bioavailability, conferring stronger antioxidant, metabolic, and renoprotective effects, making FA a promising therapeutic and bioprocessing a strategy to upgrade traditional herbs.",

Probiotics, which modulate the gut microbiome, hold considerable promise for both prophylaxis and therapeutic intervention. This requires deeper insights into the kinetic changes and molecular mechanisms upon probiotic entry into the body. In this study, we utilized advanced molecular imaging to delineate the in vivo kinetic dynamics of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations: a liquid culture and a lyophilized powder. Our results provide new insights into the gastrointestinal transit and growth kinetics of the different probiotics formulations. Strikingly, the liquid LPZ achieved its peak growth phase within a relatively short period of 6 to 8 h post-ingestion, culminating in a 270- to 680-fold increase in residues at the 24th hour post-ingestion when compared to the lyophilized powder LPZ. Furthermore, during peak in vivo replication, LPZ enhanced gut microbial diversity and enriched beneficial commensal communities. Functionally, LPZ ingestion attenuated virulence factors while upregulating carbohydrate-active enzymes. Notably, LPZ significantly reduced xanthine levels, a metabolite associated with hyperuricemia, thereby providing a mechanistic basis for the observed relief from gout symptoms. This supports the mechanism of prior clinical findings and paves the way for future clinical trials and therapeutic use of LPZ and related probiotics. The innovation of this study lies in visualizing the kinetic changes of two Lacticaseibacillus paracasei Zhang (L. paracasei Zhang, LPZ) formulations (a liquid culture and lyophilized powder) within the gastrointestinal tract. It was found that liquid LPZ proliferates in vivo with a higher retention rate. Furthermore, we also found that when liquid LPZ reaches its peak proliferation phase in vivo, it not only effectively promotes the proliferation of other beneficial bacteria and the production of their metabolites but also generates more carbohydrate-active enzymes while reducing virulence factors, thereby amplifying the functions of LPZ. Meanwhile, we observed that liquid LPZ significantly reduces the production of xanthine in vivo, indicating its potential to lower uric acid. In light of the aforementioned findings, we herein propose the concept of \"probiotikinetics.\" These results provide new insights into the intake of LPZ, along with important evidence for its application in healthy populations.",

However, the dynamic interactions among pulmonary pathology, gut microbiota, and host metabolism during these episodes remains unclear. This study aimed to delineate the longitudinal characteristics of virus-induced AECOPD and identify potential biomarkers. Mice were exposed to cigarette smoke for eight weeks, followed by intranasal inoculation with IAV. A longitudinal assessment was conducted from day 1 to day 15 post-infection, integrating analyses of lung pathology, lung function, gut microbiome, and both serum and fecal metabolomes. Additionally, random forest modeling was employed to identify specific metabolic biomarkers associated with the acute exacerbation stage. Mice exposed to cigarette smoke and IAV exhibited significant pulmonary immune cell recruitment, impaired lung function, and emphysematous changes, peaking at day 5 post-infection. By day 15, acute airway inflammation had subsided; however, interstitial immune cell infiltration, collagen deposition, and emphysema persisted. 16S rRNA sequencing revealed dynamic shifts in gut microbiota composition, with the abundance of Intestinimonas positively correlating with pulmonary inflammatory markers. Untargeted metabolomics demonstrated sustained downregulation of serum unsaturated fatty acid biosynthesis pathways from day 3 to day 15, and these metabolites were negatively correlated with lung inflammation. Random forest analysis identified 1-Methylnicotinamide (1-MNA) as a promising biomarker for distinguishing virus-triggered AECOPD, achieving an area under the curve (AUC) of 1.0. This study demonstrates that cigarette smoke combined with influenza infection induces persistent lung injury alongside concurrent disruption of intestinal flora and serum metabolism. The findings show that gut microbiota and metabolites are potential biomarkers and supplementation with unsaturated fatty acids may represent a novel therapeutic strategy for virus-induced AECOPD.",

These deficiencies are clinically relevant and may contribute to the progression of obesity-related comorbidities through interconnected pathways, including chronic low-grade inflammation, oxidative stress, gut dysbiosis, and impaired nutrient absorption. Objectives: This narrative review aims to summarize current evidence regarding the prevalence, underlying mechanisms, and clinical consequences of micronutrient deficiencies in individuals with obesity, with particular emphasis on their metabolic implications and potential therapeutic strategies. Results: Among individuals with obesity, iron, zinc, magnesium, calcium, vitamin D, vitamin B12, and folate are the most frequently reported deficiencies. These deficiencies arise from multiple mechanisms, including poor diet quality, increased metabolic demands, and compromised gastrointestinal absorption. In addition, obesity-related alterations in pharmacokinetics may further interfere with micronutrient distribution and bioavailability. Together, these mechanisms may lead to various clinical outcomes, such as anemia, immune, metabolic, and cardiovascular dysfunctions, along with cognitive impairment. Although several studies suggest that correcting these deficiencies may improve clinical outcomes, findings remain inconsistent, highlighting the complex and multifactorial pathophysiology underlying micronutrient imbalance in obesity. Conclusions: Micronutrient deficiencies represent frequently overlooked contributors to metabolic dysregulation in obesity. Their identification and correction should be considered a central part of the obesity management strategy. A personalized supplementation approach, based on clinical, biological, and pathophysiological characteristics, may provide a complementary support for weight-management treatments.",

However, its low bioavailability, limited stability in its native form, degradation during digestion, and poor solubility in water all restrict its absorption in the human body. Fermentation represents an effective biotechnological method for modifying the phytochemical composition and potentially enhancing its pharmacological effects. This study aims to explore the impact of fermentation on Zingiberaceae, focusing on the alteration of phytochemical profiles and the enhancement of pharmacological activities. Articles were sourced from the Scopus and PubMed databases and filtered for publications between 2015 and 2025; there were 2 articles that were electronically removed before screening due to duplication, yielding 62 articles. These articles were then further screened based on titles, abstracts, and full texts, resulting in five relevant studies. Fermentation was found to improve the phytochemical profile, influenced by the microbial strains used and the physicochemical properties of the phytochemicals. The fermentation process enhanced the stability of compounds, such as converting 6-gingerol to 6-shogaol and transforming glycosides into aglycones, which are more easily absorbed by the body. Additionally, fermentation increased phenolic and flavonoid content, accompanied by enhanced antioxidant and anti-inflammatory activities. Pharmacologically, in vitro studies showed that fermented extracts modulate cytokine signaling pathways in immune cells while enhancing anti-aging properties and skin barrier protection. Meanwhile, in vivo studies demonstrated improvements in metabolic regulation and neuroprotective effects in cognitive disorders. Further mechanistic investigations are needed to clarify the pathways through which fermentation influences the behavior of phytoconstituents and their pharmacological performance. This review provides an overview of preclinical fermentation studies on Zingiberaceae plants, both in vitro and in vivo, with a focus on their phytochemical composition and effectiveness in enhancing pharmacological activity.",
        "42039801": "ID: 42039801\nTitle: Consumer knowledge and motivations for consumption of fermented foods.\nAbstract: Non-alcoholic fermented foods (FFs) are a popular food group with consumers; however limited studies exist evaluating the motivations for consuming FFs and the frequency of consumption. To begin to address this gap in knowledge, we developed an online survey to assess participant familiarity with different types of fermented products, determine consumption frequency, and gain insight into the motivation for consumption. A total of 751 participants completed the survey. Yogurt was the most frequently identified fermented food (n\u202f=\u202f658; 87.62% of respondents). Participants reported consuming fermented cereal grains (n\u202f=\u202f307; 46.17%), fruits and vegetables (n\u202f=\u202f281; 42.26%), dairy products (n\u202f=\u202f204; 39.70%), soy/rice products (n\u202f=\u202f250; 37.60%) and fermented meats (n\u202f=\u202f204; 30.68%). Reported daily consumption was highest for categories of fermented cereal and dairy products, compared to the other categories which typically were consumed on a weekly or monthly basis. The primary motivator for consumption was taste (n\u202f=\u202f337; 50.68%) compared to health benefits (n\u202f=\u202f235; 35.34%) and cultural reasons (n\u202f=\u202f80; 12.03%). The most highly selected health benefits associated with FF consumption were \"improved gut microbiome\" (n\u202f=\u202f513; 77.14%), \"digestive benefits\" (n\u202f=\u202f508; 76.39%), and \"probiotic\" (n\u202f=\u202f458; 68.87%). Participants associated health benefits with all fermented products listed in the survey. Therefore, consumers may assume that all fermented foods confer the same health benefits. The motivations for consumption (sensory attributes, health benefits, cultural reasons) did not vary when individuals were asked to respond for FFs as a broad category versus specifically for non-alcoholic, fermented fruits and vegetables. This suggests that consumers view FFs similarly regardless of the starting ingredients and fermentative process involved.",

Microbial dysbiosis has been linked to disease progression, inflammation, and clinical outcomes. However, a comprehensive overview of the global research landscape and evolving themes in this field is still lacking. Publications on COPD and respiratory microbiota were retrieved from the Web of Science Core Collection (WoSCC) and Scopus databases. Bibliometric analyses, including publication trends, co-authorship networks, keyword co-occurrence, citation bursts, and thematic evolution, were conducted using VOSviewer, CiteSpace, and the bibliometrix package in R. Between 2001 and 2025, 296 publications were identified in WoSCC and 433 in Scopus, reflecting a sustained growth in research output. Keyword co-occurrence and clustering analyses revealed three main research hotspots: (1) respiratory microbiota composition and dynamics, (2) pathogen colonization and inflammation-related processes, and (3) clinically relevant outcomes. Citation burst and thematic evolution analyses demonstrated a clear temporal shift from pathogen-centered studies toward microbiota-based, dynamic, and clinically oriented research paradigms. International collaboration is increasingly prominent, with China, the USA, and the UK leading in productivity and citation impact. This bibliometric study systematically delineates the intellectual structure and evolving trends of COPD-related respiratory microbiota research. Our findings highlight the maturation of the field, reveal emerging research directions such as multi-omics integration and gut-lung axis interactions, and provide a quantitative reference for guiding future translational and microbiota-focused studies in COPD.",
        "42046064": "ID: 42046064\nTitle: SCFAs inhibited NETosis to alleviate lung inflammation in COPD: a potential role for GPR43.\nAbstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and poses a significant socioeconomic burden attributable to its high mortality and morbidity. Short-chain fatty acids (SCFAs), as the key metabolites produced by gut microbiota, have been considered to be involved in the regulation of pulmonary inflammation. However, the underlying bridging mechanisms through the gut-lung axis remain elusive. METHODS: To delineate cellular heterogeneity during COPD progression, we profiled lung tissues from rats at distinct stages (Days 0, 7, 14, and 28) using scRNA-seq, followed by bulk transcriptomic analysis to pinpoint critical dysregulated pathways. Gas chromatography-mass spectrometry (GC-MS) was employed to quantify the differential SCFA levels. The protective effects of SCFAs against pulmonary inflammation in COPD were evaluated via pulmonary function testing, HE staining, and ELISA. Flow cytometry, Western blotting, immunofluorescence and scanning electron microscopy were employed to explore the mechanism of SCFAs regulating neutrophil extracellular trap (NET) formation in vitro and in vivo. Finally, metagenomic sequencing was applied to investigate the impact of SCFAs on gut microbial communities. RESULTS: ScRNA-seq demonstrated the intense immune activation during the progress of COPD, characterized by neutrophil accumulation exceeding 50% of cellular composition on the 14th day in the lung tissue. Transcriptomic analysis further pinpointed neutrophil-driven NETosis as the key pathogenic pathway. The results of GC-MS showed the significant downregulation of SCFAs represented by acetic acid and propionic acid in COPD. Exogenous supplementation with SCFAs (acetic acid and propionic acid) activated the key receptor GPR43, suppressed the expression of NETs marker proteins (NE, MPO, and CitH3) and attenuated inflammatory cytokine levels in COPD rats. Rescue experiments with NETs inducers/inhibitors and GPR43 agonists/antagonists further elucidated the regulatory mechanisms of SCFAs/GPR43 axis in COPD inflammation. Furthermore, metagenomic sequencing revealed that SCFAs reshaped the intestinal flora in COPD by enriching the abundance of beneficial bacteria. CONCLUSION: As one of the key receptors for gut microbiota-derived SCFAs, GPR43 may be involved in the process by which SCFAs alleviate pulmonary inflammation in COPD through regulating NET formation. These findings provide valuable experimental evidence for promoting the clinical translation of therapeutic strategies characterized by gut microbiota and their metabolites.",

Although bacterial alterations in COPD have been documented, the gut mycobiome and its ecological integration with bacterial communities remain unexplored. In this study, we profiled the gut mycobiome of 61 non-small-cell lung cancer (NSCLC) patients stratified by COPD severity using ITS2 sequencing and analyzed 47 overlapping patients with available metagenomic data to construct cross-kingdom bacterial\u2013fungal networks. Alpha diversity, assessed by Shannon, Simpson, and Chao1 indices, did not differ significantly between patients with and without severe COPD. Partial least squares discriminant analysis (PLS-DA) revealed partial separation of the two groups, with COPD severity explaining 6% of overall compositional variance (R\u00b2=0.06, p\u2009=\u20090.058). COPD-severe patients exhibited a significantly reduced Ascomycota/Basidiomycota ratio (p\u2009=\u20090.039) and lower relative abundance of Mucoromycota. Analysis of compositions of microbiomes (ANCOM) identified Myrothecium and Lasiodiplodia crassispora enriched in severe COPD, while Helotiales_unclassified and Phallus atrovolvatus were more abundant in non-severe cases. Fungal co-occurrence networks demonstrated reduced connectivity and modularity in severe COPD compared with non-severe COPD. Cross-kingdom analyses integrating bacterial genera revealed strengthened Candida\u2013Enterococcus/Clostridium hubs and weakened Faecalibacterium/Roseburia\u2013yeast associations in severe disease. Keystone analysis showed increased centrality for Candida, Aspergillus, Enterococcus, and Clostridium, and decreased centrality for Akkermansia and Roseburia. A compositional balance classifier achieved high discriminatory power (AUC\u2009=\u20090.88) in distinguishing COPD-severe from non-severe patients. These findings indicate that COPD severity is not characterized by major diversity loss but by guild-specific compositional shifts and extensive network rewiring, favoring oxygen-tolerant, opportunistic taxa over short-chain fatty acid\u2013associated commensals.",

The present study investigated the impact of fermentation on the antioxidant, antiplatelet, and anti-inflammatory activities of oat- and soy-based dairy alternatives. Total lipids were extracted and fractionated into lipophilic and amphiphilic lipid fractions, which were subsequently evaluated for antioxidant capacity using 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric reducing antioxidant power (FRAP) assays, as well as for their inhibitory activity against platelet aggregation induced by platelet-activating factor (PAF) or by ADP. Fermentation significantly enhanced the biological activity of the tested products, with fermented samples exhibiting lower IC50 values and thus more potent anti-inflammatory and antiplatelet efficacy and improved antioxidant performance compared with the non-fermented plant-based dairy alternative products. The amphiphilic lipid fractions demonstrated the strongest bioactivity, suggesting that fermentation promotes structural modifications in polar lipids that contribute to enhanced functional properties. Overall, fermented soy products exhibited stronger antiplatelet (anti-ADP) and anti-inflammatory (anti-PAF) activities, with lower IC50 values (indicating higher inhibitory potency), whereas fermented oat products demonstrated particularly enhanced antioxidant capacity, especially in TAC fractions, as evidenced by higher FRAP values and carotenoid content (e.g., oat yogurt TAC: 19.14 \u00b1 9.97 mg CE/g extract). In DPPH assays, TAC fractions of both soy and oat showed comparable radical scavenging activity (TEAC \u2248 0.019 for soy yogurt TAC), while ABTS and FRAP assays highlighted matrix-dependent differences between lipid fractions. Fatty acid analysis further indicated favorable compositional changes associated with fermentation, including favorable alterations in the n-6/n-3 fatty acid ratio of the fatty acid content of the bioactive polar lipid species, while OMICs analysis indicated the specific molecular species of phospho-/glyco-based polar lipids present in these products. These findings suggest that fermentation can substantially improve the biofunctional profile of plant-based dairy alternatives and highlight fermented oat- and soy-based products as promising dietary sources of bioactive polar lipids with potential cardioprotective properties.",
        "42099600": "ID: 42099600\nTitle: The gut-lung axis: pathological crosstalk and inter-organ communication in chronic obstructive pulmonary disease and inflammatory bowel disease.\nAbstract: The significant bidirectional comorbidity risk and extensive subclinical involvement observed between chronic obstructive pulmonary disease (COPD) and inflammatory bowel disease (IBD) underscore the pivotal role of the \"gut-lung axis\" in cross-organ pathological crosstalk. Here, we comprehensively review the molecular and immunological mechanisms driving this comorbidity. Genome-wide association studies (GWAS) have substantiated genetic pleiotropy that underpins a shared susceptibility to mucosal defense deficits. The \"common mucosal immune system\" (CMIS), rooted in embryonic homology, constitutes the anatomical basis for this pathological interplay, wherein aberrant immune cell homing, Th17/Treg imbalance, and the cross-organ trafficking of innate lymphoid cells (ILCs) mediate the distal dissemination of inflammation. Furthermore, gut dysbiosis-induced depletion of short-chain fatty acids (SCFAs), acting in concert with systemic hypoxia and the IL-23/IL-17 axis, potentiates synergistic injury to the gut-lung barriers. We highlight the reciprocal, bidirectional causality of this \"hypoxic loop\" and its testable mechanistic predictions for barrier dysfunction. Furthermore, we evaluate pharmacological evidence from drug repositioning, alongside a critical examination of the \"hidden axis\" of clinical therapies as profound iatrogenic confounders. Elucidating these mechanisms is critical for establishing systemic diagnostic and therapeutic strategies; interventions targeting shared molecular targets and the microbiota hold promise for achieving a simultaneous treatment approach for these distinct pathologies.",
        "42099859": "ID: 42099859\nTitle: Complex food matrices reveal microbiota-nutrient balance interactions that modulate gut microbiome diversity in vitro.\nAbstract: Diet-microbiome relationships are often evaluated using isolated nutrients, yet microbes encounter complex food matrices in which nutrient accessibility and baseline microbial community context jointly shape gut fermentation outcomes. This study integrated an in vitro digestion and gut fermentation to examine the nutrient-baseline microbiota interaction to modulate community diversity. Nutrient-defined matrix classes were grouped using free saccharides, free amino acids, and free fatty acids content in food digesta. Two machine learning models-a classification model that predicted nutrient-defined matrix class from genus-level relative abundance changes (0-12\u202fh) and regression models that predicted \u03b1-diversity change using nutrient and baseline (0\u202fh) community features-were developed. SHAP-based feature attribution revealed that three nutrient-defined matrix classes exhibited distinct microbial response signatures (Turicibacter/Alistipes/Staphylococcus-centered), suggesting post-digestion nutrient associations with gut microbial restructuring patterns. However, \u03b1-diversity shifts within the same nutrient class were bidirectional, and inclusion of baseline microbiota features improved model performance for predicting diversity change from R2\u202f=\u202f0.34 to R2\u202f=\u202f0.72, consistent with a role for baseline-nutrient interactions. Fermented food matrices further illustrated that food-associated microbial contexts can modify restructuring trajectories beyond nutrient profiles. Overall, these findings propose that diversity outcomes during fermentation may depend on baseline-conditioned responses to bioaccessible nutrients, highlighting a matrix-specific but context-dependent diet-microbiome effects.",
        "42110505": "ID: 42110505\nTitle: Potential Benefits of Gut Microbiota Modulation in Chronic Obstructive Pulmonary Disease.\nAbstract: The gut-lung axis is increasingly recognized. This study aimed to find out whether and how the gut microbiome involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). Gut microbiota was characterized via 16S rRNA gene sequencing in COPD patients and a smoking-induced mouse model. Gut dysbiosis was induced by antibiotic cocktail (ABX) and restored by fecal microbiota transplantation (FMT). Plasma metabolomics was conducted using liquid chromatography-mass spectrometry (LC-MS), and pathway analysis was performed with MetaboAnalyst 5.0. Differentially expressed genes were identified by RNA sequencing and functionally interpreted through gene set enrichment analysis (GSEA). Both COPD patients and mice showed altered gut microbiota, characterized by a unique microbial composition and reduced diversity. ABX induced gut dysbiosis exacerbated pathological lung changes, impaired lung function, and promoted Treg cell exhaustion in COPD mice. Restoration of gut homeostasis via FMT attenuated these alterations. Higher plasma levels of acetylcholine (ACh) were observed in COPD mice, while the highest ACh levels were found in ABX treated COPD mice compared to controls. Notably, ACh levels correlated positively with genus Parasutterella, which was more abundant in COPD mice, and inversely with genera Candidatus Saccharimonas and Lactobacillus, which were predominant in control mice. Metabolomic pathways analysis revealed enrichment in unsaturated fatty acids biosynthesis and purine metabolism in COPD mice relative to controls. These findings highlight the involvement of the gut microbiome in COPD development and suggest that maintaining gut homeostasis may represent a novel therapeutic strategy for COPD.",
        "42130486": "ID: 42130486\nTitle: Fermented Dairy Products as Modulators of the Gut Microbiome: Greek Yogurt as a Model System.\nAbstract: Greek yogurt, characterized by its thick texture and higher protein content, contains reduced lactose levels while still preserving large colonies of active bacteria when compared to conventional (or \"traditional\") yogurt. The starter cultures listed on its label do more than just ferment milk; they actively reshape the gut microbiome and adjust host physiology. This review examines currently available observations about distinct bacterial types within this product, especially regarding its effects on intestinal balance. The ability to produce short-chain fatty acids is a property linked to these strains, along with the potential to stabilize gut lining function, adjust immunity patterns, aid blood sugar regulation, and even offer possible cardiovascular benefits. Greek yogurt's properties and potential differ from other fermented food items. Findings from experimental and clinical research suggest the lactic acid and Bifidobacterium species found in Greek yogurt contribute to increased microbiota variety, encourage growth of butyrate-producing bacteria, and strengthen the intestinal lining. Inflammation levels are reduced by these microbes, leading to greater lactose tolerance, smoother digestion, and balanced metabolic activity. Still, much of the available data is limited because most studies do not distinguish Greek yogurt from conventional yogurt in their analyses, even though differences exist in live cultures, survival through digestion, and manufacturing. Fermented vegetables may offer wider microbe variety; however, consistency in bacterial strains and stronger clinical evidence gives Greek yogurt significance in nutritional and microbiome research. Future investigations should focus on Greek yogurt and prioritize direct comparisons to other fermented foods. To credibly refine dietary recommendations, improved microbial methodologies and expanded trials among diverse populations are warranted.",
        "42131229": "ID: 42131229\nTitle: Mechanisms by which complex carbohydrates influence immune imbalance in COPD via the gut-lung axis: from colonic fermentation to pulmonary immune responses.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized not only by local airway inflammation and tissue injury, but also frequently by persistent systemic immune imbalance. After entering the colon, complex carbohydrates can be converted by the gut microbiota into gut-derived molecules such as short-chain fatty acids (SCFAs) and tryptophan metabolites, which may further influence the pulmonary immune status in COPD. These effects are mainly related to the regulation of colonic fermentation kinetics and metabolite production by substrate structure, as well as to the actions of selected metabolites on pulmonary immune cells and airway epithelium after intestinal absorption and systemic distribution. The monosaccharide composition, glycosidic linkage type, degree of branching, and degree of polymerization of complex carbohydrates can affect colonic fermentation kinetics and further alter the production ratio of SCFAs and tryptophan metabolites. SCFAs are the main candidate metabolites linked to the regulation of aberrant neutrophil recruitment, alveolar macrophage inflammatory status, the Treg/Th17 balance, and airway epithelial barrier integrity; selected tryptophan metabolites are mainly involved in mucosal defense and epithelial repair. In COPD, bile acids are more likely to be associated with microaspiration from gastroesophageal reflux and local microecological alterations. Complex carbohydrates may participate in the regulation of immune imbalance in COPD by affecting the production, distribution, and local pulmonary actions of gut-derived metabolites, but the quantitative relationships among these processes across the gut, blood, and lung, as well as their specific pulmonary effects in COPD, still require further clarification, particularly in human studies with synchronized sampling.",

This study investigated the combined toxicity of polyethylene microplastics (PE MPs) and levofloxacin (LEV) in zebrafish using integrated untargeted metabolomics and gut microbiome profiling. Zebrafish were exposed to environmentally relevant concentrations of LEV (0.1\u00a0\u03bcg/L, 1\u00a0\u03bcg/L, 100\u00a0\u03bcg/L), PE (1\u00a0mg/L), and their combinations for 96\u00a0h. LEV exposure produced concentration-dependent metabolic toxicity, progressing from energy conservation at 0.1\u00a0\u03bcg/L to inflammatory activation at 1\u00a0\u03bcg/L, and ultimately to system-wide metabolic perturbation at 100\u00a0\u03bcg/L. PE independently disrupted oxidative stress and membrane integrity pathways. Co-exposure generated emergent interactive effects exceeding additive predictions, with PE\u00a0+\u00a0LEV 0.1\u00a0\u03bcg/L affecting 387 metabolites versus 245 for LEV alone. Crucially, co-exposure elicited synergistic toxicity with unique metabolic fingerprints-including neuroendocrine activation (dynorphin B) and mTOR signaling modulation-that were absent in individual treatments. Conversely, microbiome analysis revealed an antagonistic interaction; while LEV alone caused significant dysbiosis and enrichment of resistant taxa, co-exposure stabilized microbial diversity and composition, likely due to LEV adsorption onto PE particles reducing luminal bioavailability. These findings highlight a \"microbiome-host interaction paradox\": PE mitigates antibiotic-induced gut dysbiosis yet exacerbates host systemic toxicity through mechanisms of epithelial barrier disruption and pharmacokinetic modulation. This study demonstrates that microbiome stability does not reliably predict host physiological health under multi-stressor conditions, underscores the importance of integrative, multi-omics approaches to assess the emergent risks of complex environmental mixtures.",

In its most serious manifestations, it can cause death by asphyxiation. Currently, no efficacious therapeutic interventions exist to avert or counteract these serious outcomes. Baicalein (BAI) is a core quality marker of the traditional Chinese medicine Scutellaria baicalensis, but the mechanism of its oral action remains unclear. Assess the therapeutic efficacy of BAI in AA mice models and investigate its mechanism of action. Evaluate the efficacy of BAI on ovalbumin-induced AA mice. To assess alterations in the pulmonary and gut microbial communities, 16S rRNA sequencing was employed. The integrity and restoration of the lung and intestinal epithelial lining were evaluated via immunohistochemistry. Furthermore, gas chromatography-mass spectrometry quantified fecal levels of short-chain fatty acids (SCFAs) in AA mice, and flow cytometry was used to analyze the content of ILC2 cells in colon tissue. Finally, the role of beneficial bacteria and their metabolites in inhibiting AA was further confirmed through fecal microbiota transplantation (FMT). Oral BAI effectively alleviated AA-related lung epithelial damage and microbiota dysbiosis, while elevating the production of the tight junction proteins. Moreover, BAI mitigated colonic epithelial damage, inhibited ILC2s activation in the colon, enriched the abundance of gut probiotics capable of producing SCFAs, especially Akkermansia muciniphila (A. muciniphila), and increased the content of SCFAs such as propionic acid in feces. The FMT experiment conducted after gavage with broad-spectrum antibiotics confirmed that BAI mediated reversal of microbial dysbiosis plays a key role in the treatment of AA, significantly increasing the expression of GPR41 mRNA in colon tissue and inhibiting the activation of ILC2s. The potential prebiotic BAI mitigates AA via targeting A. muciniphila and its metabolites, which consequently inhibits epithelial damage and type 2 immune activation.",
        "42180251": "ID: 42180251\nTitle: Proton pump inhibitor exposure modulates functional and transcriptional responses in Lactobacillus acidophilus: a comprehensive computational and experimental insights.\nAbstract: Proton pump inhibitors (PPIs) are among the most widely prescribed medications for gastric acid-related disorders. However, their effect on the gut microbiota remains incompletely understood, despite emerging evidence suggesting potential long-term alterations in microbial composition and reductions in beneficial taxa. In this study, Lactobacillus acidophilus, a well-known probiotic species, was used as a representative model organism to investigate the microbiological effects of PPIs. This specific bacterium is linked to immune modulation, vitamin metabolism, and the preservation of the epithelial barrier. The effects of PPIs on L. acidophilus at the structural and functional levels were elucidated by an integrated framework including subtractive genomics, molecular docking, molecular dynamics (MD) simulations, antimicrobial assays, and transcriptional analysis. Using a multi-criteria scoring system, essential, non-redundant, non-human homologous cytoplasmic proteins were ranked and mapped to important pathways such as ATP synthesis, peptidoglycan biosynthesis, amino-sugar metabolism, nucleotide metabolism, and protein maturation. Molecular docking suggested potential binding of pantoprazole and rabeprazole to targets such as MurA, MurB, MurE, GlmS, NadE, AtpD, Def, and PyrH proteins. MD simulation showed stable protein-PPI complexes with localized flexibility changes near catalytic domains while preserving the global fold. Consistent with in-silico expectations, both pantoprazole and rabeprazole exhibited dose-dependent growth inhibition of L. acidophilus, whereas qRT-PCR revealed transcriptional downregulation of genes involved in cell-wall production, NADH metabolism, and energy generation. Pantoprazole elicited the most uniform transcriptional suppression, whereas rabeprazole had stronger but more varied effects. The present findings provide preliminary insights into potential interactions between PPIs and probiotic bacteria at the molecular and cellular levels. However, the results reflect species-specific responses under in vitro conditions and should be interpreted cautiously, as transcriptional changes do not directly confirm functional inhibition and the concentrations tested may represent upper-range exposure scenarios. Further in vivo and multi-species studies are required to validate this observation and better understand their clinical implications for microbiome stability during PPI therapy.",

In teleosts, the intestinal mucosa represents a principal portal of viral entry, compromising barrier integrity, yet the mechanisms by which yeast nucleotides potentiate antiviral defenses remain to be elucidated. Herein, this study performed an eight-week feeding trial of coho salmon with graded yeast nucleotide levels (0, 125, 250, 500, and 1000\u00a0mg/kg), followed by intraperitoneal IHNV challenge with sampling at four\u00a0days post-infection, and an in vitro assessment of intestinal mucus from the control and 500\u00a0mg/kg groups co-incubated with EPC cells and IHNV to evaluate antiviral efficacy. Coho salmon showed a biphasic growth response to dietary yeast nucleotides, with the 500\u00a0mg/kg group achieving the highest growth among all treatments. Yeast nucleotide enhanced intestinal tight junction integrity by upregulating proteins, such as Occludin, and potentiated mucosal immunity via modulation of NF-\u03baB p65. Notably, yeast nucleotides reshaped gut microbiota and were associated with changes in lipid metabolism and increased levels of bioactive metabolites, with taxa such as Romboutsia, Bacillus, Turicibacter and Clostridium sensu stricto\u202f1 showing significant correlations with these metabolic and immune parameters, although direct functional roles remain to be confirmed. Upon IHNV challenge, the 500\u00a0mg/kg group demonstrated significantly reduced cumulative mortality and ameliorated virus-induced disruption of intestinal barrier function compared to the control group. Finally, intestinal mucus from 500\u00a0mg/kg yeast nucleotides-fed fish conferred antiviral protection in vitro by upregulating host antiviral gene expression in EPC cells. These findings highlight dietary yeast nucleotides as key modulators of antiviral defense and intestinal barrier integrity potentially through microbiota-associated lipid metabolism and bioactive metabolite profiles, while acknowledging that further functional studies are required to establish causality, offering promising nutritional strategies against virus-induced gut injury.

A total of 104 participants including 74 stable COPD patients and 30 healthy controls from northern China were recruited, and shotgun metagenomic sequencing and untargeted metabolomics were performed. Results showed that alpha diversity of the gut microbiota did not differ significantly between COPD patients and healthy controls, whereas beta diversity showed clear separation. Marked differences in microbial composition from phylum to species levels (e.g., Oscillospiraceae) and altered microbial functions (signal transduction, antibiotic resistance, etc.) were observed in COPD patients. Metabolomic profiling identified 497 differential fecal metabolites and 1260 differential serum metabolites in COPD patients. Importantly, serum riboflavin levels were significantly reduced and positively correlated with pulmonary function indices as well as the key differential gut microbial functional gene K11752. Serum metabolite eremopetasinorol exhibited high diagnostic accuracy for COPD (AUC = 0.947, 95% CI: 0.8-0.98), surpassing fecal metabolites and microbial features. This study provides integrated metagenomic and metabolomic characterization of gut microbiota alterations in Chinese COPD patients, offering novel insights for biomarker discovery and targeted intervention strategies.",

Extract Supplementation on the Gut Microbiota, and Serum Metabolome in Lambs.\nAbstract: Salvia sclarea L. extract contains various bioactive components such as flavonoids and fatty acids, exhibiting anti-inflammatory, antioxidant, and antibacterial properties. This study aimed to investigate the effects of Salvia sclarea L. extract on the gut microbiota and serum metabolome in lambs. Sixty 2-month-old Chinese Merino female lambs (body weight 20 \u00b1 2 kg) were randomly assigned to five groups. The control (CK) group received the basal diet only, while the treatment groups received the basal diet supplemented with 0.04 mL/kg (CL1), 0.08 mL/kg (CL2), 0.12 mL/kg (CL3), and 0.16 mL/kg (CL4) of Salvia sclarea L. extract, respectively. The results showed that Firmicutes, Bacteroidetes, Spirochaetes, and Proteobacteria were identified as the dominant phyla across all groups (>90%). Compared with the CK group, CL1 and CL2 groups significantly reduced the relative abundance of Tenericutes (decreased by 38.2% and 32.9%, respectively, p < 0.05); the relative abundance of Patescibacteria in the CL1 group was significantly lower (decreased by 55.2%, p < 0.05). At the genus level, Ruminococcaceae constituted a substantial proportion, including Ruminococcaceae UCG-005, UCG-010, UCG-014, and NK4A214 group. STAMP analysis revealed that Klebsiella was significantly enriched in CL2, CL3, and CL4 groups compared to the CK group (p < 0.05). Correlation analysis between microbiota and immune indices showed that Christensenellaceae R-7 group was significantly negatively correlated with TNF-\u03b1 (p < 0.05); Ruminococcaceae UCG-005 was significantly negatively correlated with IFN-\u03b3 (p < 0.05) and showed a negative correlation trend with immunoglobulins (IgA, IgG, IgM). Conversely, Ruminococcaceae UCG-014 was significantly positively correlated with IL-4 (p < 0.05) but showed a negative correlation trend with IgM. Untargeted metabolomics analysis identified 8, 18, 25, and 20 differential metabolites in CL1, CL2, CL3, and CL4 groups, respectively. Notably, 3-hydroxy-7-methoxyflavone and Gamma-Glu-Cys were significantly upregulated across all treatment groups. KEGG pathway enrichment analysis indicated that these differential metabolites were primarily involved in nucleotide metabolism, fatty acid biosynthesis, and oxidative stress-related pathways. Further Spearman correlation analysis revealed significant associations between gut microbiota and differential metabolites. Specifically, g_Klebsiella was significantly positively correlated with 3-Hydroxycapric acid and 3-hydroxy-7-methoxyflavone (p < 0.05). In conclusion, Salvia sclarea L. extract modulates host energy metabolism by regulating nucleotide metabolism and fatty acid biosynthesis, and enhances immune function by alleviating oxidative stress, through the remodeling of gut microbiota and serum metabolome.",

These fungal foods are often high in protein and fiber and are generally regarded as nutritious. This narrative review examines current knowledge on how mycelia from molds, including edible strains of Aspergillus, Rhizopus, Neurospora, Fusarium, Mucor, and Paecilomyces, affect the gut microbiome. Allfour human trials on these foods (two extracts, one biomass, and one fermented food) reported a measurable effect on the gut microbiome. These studies, plus the additional eight animal and eight in vitro studies performed, frequently found increases in the proportions of intestinal Akkermansia, Bifidobacterium, and lactobacilli. Bacteroides, Roseburia, and Eubacterium, which are recognized for their roles in fiber metabolism, were also frequently enriched, and numerous studies reported increases in fecal short-chain fatty acids. Notably, effects on the gut microbiome may be fungal species and food format-dependent. Although \u03b2-glucans and chitin are likely key determinants of gut microbiome responses to dietary mycelium, future studies should investigate how these and other potentially bioactive components of mycelia and fungal metabolites are metabolized by intestinal microorganisms. Such studies will result in an improved understanding of how myco-foods could support human health.",

This study aims to explore the potential mechanisms of secondary failure of sulfonylureas (SFS) and to identify reliable predictive biomarkers. In this study, 16S rDNA sequencing technology and non-targeted metabolomics were used to analyze the differences in gut microbiota and metabolic products between the SFS and sulfonylurea effective (SE) groups. The results of 16S rDNA sequencing indicated that there are differences in composition between two groups. Seventeen different bacterial types were identified, including six types from SFS patients and eleven from SE. SFS might be linked to disturbances in energy metabolism, amino acid metabolism, nucleotide metabolism, and lipid metabolism within the gut microbiota. Metabolomics results showed 66 different metabolites between two groups (49 metabolites were upregulated, and 17 metabolites were downregulated). Correlation analysis between gut bacteria and fecal metabolites revealed that 4 types of gut bacteria were significantly linked to 5 types of metabolites. This study reveals distinct gut microbiota composition in patients with sulfonylurea secondary failure, helping us understand changes in gut metabolites and providing new biomarkers for personalized treatment.",

The Mulberry-dyke and Fish-pond system, used in China for millennia, suggests a circular approach, yet the underlying mechanism remains poorly understood. In this study, silkworm excrement (SE) from traditional sericulture (TSE) and modern insect factories (ISE) was evaluated as a functional aquafeed. Body weight, gut histology, and immunohistochemistry were employed to assess host health. Gut microbiome, electronic tongue analysis, and muscle metabolomics were conducted to assess fish flavor and identify flavor-related microorganisms. A single-strain feeding experiment further validated the microbiome-gut-muscle axis using electronic tongue analysis, gut transcriptomics, and determination of free amino acids and nucleotides. SE supplementation maintained fish yield while improving intestinal structure. Compared with commercial feed (CF), both SE treatments increased gut microbial diversity and community stability, and more than half of the significantly different ASVs were shared between the TSE and ISE groups, mainly involving immune regulation, nutrient metabolism, and flavor formation. SE, particularly TSE, enhanced antioxidant capacity and reduced lipid peroxidation, possibly through microbial regulation of lysophosphatidylcholines. As consistently indicated by electronic tongue and muscle metabolomics analyses, SE significantly improved fish flavor, with increased umami and reduced bitterness. Network analysis and single-strain feeding further suggested that Methylorubrum populi, Gemmobacter aquatilis, and Rhodobacter sphaeroides contributed to flavor improvement by regulating host amino acid and nucleotide metabolism along the microbiome-gut-muscle axis. These findings highlight SE as a promising sustainable bioresource for aquaculture.",

Using a high-purine diet-induced HUA mouse model, this study evaluated kidney, colon, and gut microbiota damage and investigated the effects of Psidium guajava basal postbiotics (PGP). PGP reduced xanthine oxidase activity, modulated purine metabolism, and increased beneficial gut bacteria (Akkermansia muciniphila) and short-chain fatty acids (acetate, butyrate, propionate). This led to decreased blood urea nitrogen, creatinine, and renal malondialdehyde, along with reduced inflammatory factors (IL-8, LPS). Consequently, PGP alleviated HUA and mitigated HUA-induced kidney and colonic damage.

Its role in the pathogenesis of acute pancreatitis (AP), particularly in gut-pancreas crosstalk and the underlying molecular mechanisms, remains poorly understood. This study integrates clinical epidemiology (UK Biobank cohort and the Third Xiangya Hospital cohort), (L-arginine-induced AP mouse models), and multi-omics analyses (RNA sequencing, fecal metabolomics, and gut microbiome profiling) to elucidate the role and mechanistic pathways of uric acid in the onset and severity of AP. Key molecular targets and regulatory relationships identified were further validated via in vitro cellular experiments using pancreatic acinar cells and bone marrow-derived macrophages. In the UK Biobank cohort, over a median follow-up period of 13.69 years, participants in the highest uric acid quartile exhibited a significantly increased risk of developing AP compared to the lowest quartile (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.10-1.43). In the Third Xiangya Hospital cohort, AP patients with elevated serum uric acid levels exhibited more severe symptoms. The combination of uric acid and calcium demonstrated superior predictive capability for AP severity (AUC 0.9504). In the preclinical models, HUA aggravated AP progression, as demonstrated by increased pancreatic histopathological damage, elevated serum amylase levels, multi-organ dysfunction, and higher mortality. Mechanistically, HUA exacerbated AP in mice via cannabinoid receptor 1 (CNR1)-mediated retrograde endocannabinoid signaling, which enhanced macrophage-derived IL-1\u03b2 and IL-6 production. Metabolomics revealed that the gut-derived flavonoid maesopsin exerted a protective anti-inflammatory effect in the context of HUA-augmented AP. Additionally, Limosilactobacillus genus, particularly Limosilactobacillus reuteri D, was enriched in the HUA\u2009+\u2009AP group and strongly associated with maesopsin levels. Uric acid exacerbates AP progression via CNR1 driven inflammatory signaling and modulates gut microbiota composition and metabolism. Serum uric acid, especially when combined with calcium, may be integrated into routine clinical assessment for AP risk stratification and severity prediction, while CNR1 and gut microbiota-related targets provided potential directions for the developing adjunctive therapies for HUA-associated AP.",

We hypothesize that differences in gut microbiota and metabolites contribute to differences in emphysema severity through the gut-lung axis. In this study, we compared the microbiome and metabolome among non-emphysema, non-severe emphysema and severe emphysema groups. Additionally, the impact of fecal microbiota transplantation from non-emphysema, non-severe emphysema and severe emphysema groups on emphysema were investigated. A total of 78 participants with a smoking history were included in this study and categorized into three groups: non-emphysema, non-severe emphysema, and severe emphysema. Gut microbiota and metabolites were analyzed, and germ-free mice underwent fecal microbiota transplantation with feces from donors representative of each group prior to smoking exposure. Significant differences in gut microbiota and metabolites were observed among the groups, with lower acetic acid levels in patients with severe emphysema, and a greater abundance of Prevotellaceae and Megasphaera in patients without emphysema. Fecal microbiota transplantation from donors with severe emphysema worsened lung pathology in mice subjected to smoking exposure, whereas fecal microbiota transplantation from donors without emphysema attenuated emphysema development. Gut microbiota and metabolites in participants with a smoking history differ according to the presence of emphysema and its severity, and can affect emphysema development. This suggests a role for gut microbiota in lung disease and provides a foundation for exploring gut microbiota as a potential therapeutic target for chronic obstructive pulmonary disease.",

Its high morbidity and mortality have posed a substantial public health burden, with current symptomatic treatments exhibiting inadequate control and potential adverse effects. With advances in microecological research techniques, the critical role of microbial homeostasis in the oral cavity, lungs, and gut in respiratory health has become increasingly prominent, and microbial dysbiosis is closely associated with progression and therapeutic outcomes of COPD. This review summarizes the compositional alterations of oral, lung, and gut microbiota in COPD patients, analyzes the interactions of the oral-lung axis and gut-lung axis, and delineates three mechanisms through which microbial dysbiosis promotes COPD progression: pathogenic bacterial migration, abnormal metabolite production and immune dysregulation. Additionally, this review summarizes Western and traditional Chinese medicine interventions targeting microbiota homeostasis, including antibiotics, microecological preparations, and herbal medicines, which have shown potential in improving COPD clinical outcomes. This review aims to provide a theoretical reference for the clinical diagnosis and management of COPD. Millions of people worldwide live with chronic obstructive pulmonary disease (COPD), which brings persistent breathing struggles that disrupt their daily living. Current standard treatments mainly relieve symptoms, but have limited effects on controlling disease progression, and may cause unwanted side effects. Mounting research shows that microbes in the mouth, lungs and gut play a critical role in maintaining lung health, while their imbalance can drive COPD progression. This review focused on the link between microbial balance and COPD to find new intervention ideas. We summarized changes in oral, lung, and gut microbes in people with COPD, and clarified how microbial imbalance exacerbates COPD via pathogen spread, abnormal metabolites and immune disorders. We also sorted out Western and traditional Chinese medicine strategies that restore microbial balance to improve COPD treatment and quality of life. These findings show a promising strategy for COPD therapy from the perspective of regulating microbial balance.",

However, traditional diversity metrics fail to capture the complex spatial organization of microbial communities. This study addresses this gap by applying the novel metagenomic Diversity-Area Relationship (m-DAR) model to investigate scaling laws in the gout microbiome-quantifying how metagenomic diversity changes with the number of individuals sampled. Our analysis of gut microbiomes from gout patients and healthy controls revealed fundamental ecological disruptions. We found that gout microbiomes exhibited significantly altered scaling patterns: they showed greater inter-individual dissimilarity (higher z-values) at the level of rare genes (q\u2009=\u20090), but weaker scaling of dominant genes (q\u2009=\u20091-3) compared to healthy controls. Crucially, the maximal accrual diversity (MAD) was substantially lower in gout patients, indicating a severely constrained potential for total microbial gene diversity. Furthermore, profiling of metagenomic functional gene clusters (MFGCs) uncovered widespread functional perturbations, including increased diversity scaling for carbohydrate-active enzymes (CAZy) but decreased scaling in essential metabolic pathways (KEGG, KO). These results demonstrate that the gout gut microbiome is defined by a loss of ecological structure, featuring reduced homogeneity in dominant taxa, expanded rare biosphere variation, and an overall collapsed diversity capacity. This work introduces an ecological framework for characterizing dysbiosis in gout that complements traditional diversity metrics and may inform the development of microbiome-based therapeutic strategies. Further research is needed to translate these ecological patterns into clinical applications.",

This study investigated the synergistic effects and underlying mechanisms of polystyrene NPs and ABM at environmentally relevant concentrations in juvenile rainbow trout (Oncorhynchus mykiss) during a 28-day exposure. Compared to ABM alone, co-exposure with NPs induced significantly greater synergistic toxicity. This was evidenced by exacerbated intestinal barrier dysfunction, including downregulation of tight junction proteins (Occludin, Claudin-23, ZO-1) and a shift in the gut microbiota characterized by the enrichment of potential pathogens, such as Neochlamydia. In the liver, the combined exposure markedly enhanced oxidative stress and inflammatory responses. Untargeted metabolomics further revealed that the co-exposure disturbed fundamental metabolic pathways more profoundly than either contaminant alone, particularly affecting amino acid, carbohydrate, and nucleotide metabolism. Critically, correlation analyses integrated gut microbiota dysbiosis with hepatic metabolic disorders, supporting a pivotal role for gut-liver axis disruption in the synergistic toxicity. Our findings demonstrate that NPs can act as an aggravating factor, significantly potentiating the physiological and toxicological impacts of ABM on fish via interconnected intestinal and hepatic pathways. This study provides crucial mechanistic insights for the risk assessment of pesticide interactions with emerging contaminants in aquatic environments.",

This study aimed to systematically analyse literature on TCM nursing interventions for COPD complicated by GI dysfunction, using bibliometric methods to identify research trends, thematic structures, and future research directions. This study conducted a bibliometric analysis of relevant literature. Publications from 2015 to 2025 on TCM nursing for COPD with GI dysfunction were retrieved from the Web of Science, PubMed, Scopus, and China National Knowledge Infrastructure. After removing duplicates, 1,563 relevant publications were analysed. Bibliographic data were extracted and analysed using CiteSpace, VOSviewer, and bibliometrix (R package). Annual publication volume exhibited steady growth, peaking in 2024. China emerged as the primary research contributor, collaborating extensively with the USA, Australia, and European nations. Institutional analysis revealed key research centres predominantly located in China, with increasing international cooperation. Core authors, such as Chen Wang and Ke Huang, significantly influenced research collaboration networks. Major thematic clusters included pulmonary rehabilitation, quality of life improvement, gut-lung interactions, and molecular mechanisms. Landmark references reflected the growing integration of TCM nursing into conventional COPD care and the increasing attention on patient-centred outcomes. Research in this niche is increasingly oriented towards rehabilitation-focused integrative care and mechanism-informed perspectives (gut-lung axis). Future studies should prioritise a GI-inclusive core outcome set, standardised reporting of nursing-deliverable TCM modalities, and pragmatic/hybrid effectiveness-implementation designs aligned with gut-lung-related hypotheses.",

Emerging evidence highlights the gut-lung axis as a potential therapeutic target, with probiotics proposed to modulate Th17-related inflammatory pathways. In this randomized, double-blind, placebo-controlled trial, 50 patients with mild-to-moderate COPD were enrolled; 44 completed the 8-week intervention (23 probiotics, 21 placebo). Participants received either a multistrain probiotic formulation or placebo. Outcomes included spirometry, COPD Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, and serum IL-6, IL-17, and TGF-\u03b2 levels. Probiotic supplementation significantly improved FEV1 and FVC within the intervention group, although between-group spirometric differences were not significant. IL-6 levels declined significantly following probiotic therapy, with a significantly greater reduction compared to placebo, whereas IL-17 and TGF-\u03b2 remained unchanged. CAT scores improved significantly in the probiotic group, exceeding the minimal clinically important difference and demonstrating a significant between-group effect. No significant change was observed in mMRC scores. Eight weeks of probiotic supplementation was associated with reduced systemic IL-6 levels and clinically meaningful improvement in patient-reported outcomes in mild-to-moderate COPD. These findings support a potential adjunctive role for probiotics and warrant larger mechanistic trials.

To resolve the inherent heterogeneity in COPD microbiome research, we developed a standardized pipeline termed as Ontology-based Evidence Synthesis and Reasoning (O-ESR), utilizing the Ontology of Host-Microbiome Interactions (OHMI) framework. Our analysis included over 30 studies and identified more than 100 significantly altered bacterial taxa in the human airway and gut microbiomes of human COPD patients across three clinical conditions: COPD versus healthy controls, exacerbation versus stable states, and severe versus moderate diseases. Profiling across taxonomic levels revealed a marked airway expansion of pathogenic genera, including Haemophilus, Moraxella, Pseudomonas, and Burkholderia. Species-level analysis confirmed the specific enrichment of Haemophilus influenzae and Pseudomonas aeruginosa, supporting their roles in airway inflammation and exacerbation susceptibility. In contrast, the gut microbiome of COPD patients exhibited a decrease of beneficial anaerobes involved in short-chain fatty acid (SCFA) production, including Bifidobacterium bifidum, Faecalibacterium prausnitzii, and members of Lachnospiraceae and Ruminococcaceae. Notably, ontology-based reasoning identified a shared depletion of commensal genera such as Prevotella and Veillonella across both anatomical sites and all three clinical conditions, indicating a systemic and progressive loss of microbial diversity. This integrated analysis reveals a COPD-associated microbial landscape characterized by airway Proteobacteria expansion and gut SCFA-producer depletion, suggesting coordinated epithelial dysfunction, immune dysregulation, and gut-lung axis involvement. These findings demonstrate the power of ontological reasoning in decoding complex host-microbiome interactions, providing a robust foundation for microbiome-informed stratification and targeted interventions in COPD management.",
        "42292489": "ID: 42292489\nTitle: Dual role of IL-17A in COPD: amplifier of inflammatory cascades and mediator of airway remodeling and alveolar destruction.\nAbstract: Corticosteroid resistance remains a central challenge in managing chronic obstructive pulmonary disease (COPD). This refractory phenotype is primarily driven by persistent, neutrophil-dominated airway inflammation. Interleukin-17A (IL-17A) bridges innate and adaptive immunity and helps sustain this refractory inflammation, although it operates within a redundant cytokine network and its pathogenic contribution is clearest in a defined molecular subset of patients. Following an overview of upstream drivers including lung-gut microbiome dysbiosis and Th17/Treg immune imbalance, the downstream effector network of IL-17A is analyzed. In sustaining inflammation, IL-17A stabilizes pro-inflammatory transcripts via ACT1-mediated post-transcriptional regulation and produces a self-amplifying positive feedback loop with neutrophil extracellular traps (NETs). In tissue remodeling, IL-17A induces alveolar epithelial ferroptosis via the ACT1-TRAF6-p38 MAPK cascade to drive emphysema. It also mediates irreversible structural alterations in the airway and alveolar parenchyma by inhibiting fibroblast autophagy through the PI3K/AKT/mTOR pathway and inducing epithelial mucus hypersecretion. Given the lack of significant clinical benefit from early non-selective IL-17A blockade in unselected populations, precision intervention strategies guided by clinical endotypes are evaluated. Optimizing next-generation targeted therapies in COPD necessitates biomarker-driven patient stratification, coupled with upstream signal interception and the restoration of systemic immune homeostasis. Together, these strategies support a shift from symptomatic management toward endotype-specific disease modification.",

Natural polysaccharides-high-molecular-weight carbohydrate polymers derived from plants, fungi, marine organisms, and animal sources-have emerged as a promising class of multi-target bioactive agents for T2DM management. This comprehensive review first outlines the key pathophysiological mechanisms of T2DM, encompassing insulin resistance, pancreatic \u03b2-cell dysfunction, chronic inflammation, oxidative stress, and gut microbiota dysbiosis. We then systematically review the natural sources and structural classification of polysaccharides, alongside their extraction and purification methods. The core of this review examines the molecular mechanisms by which natural polysaccharides ameliorate T2DM: (1) enhancing insulin sensitivity and glucose metabolism via the PI3K/Akt and AMPK signaling pathways; (2) protecting pancreatic \u03b2-cells from apoptosis and promoting insulin secretion; (3) suppressing chronic inflammation through NF-\u03baB and NLRP3 pathway inhibition; (4) attenuating oxidative stress via Nrf2/HO-1 pathway activation; and (5) restoring gut microbiota homeostasis, reinforcing intestinal barrier integrity, and elevating short-chain fatty acids production. Structure-activity relationship analyses indicate that hypoglycemic efficacy is tightly correlated with molecular weight, monosaccharide composition, glycosidic linkage types, degree of branching, three-dimensional conformation, and chemical derivatization. Finally, challenges surrounding clinical translation, standardization, and bioavailability are discussed, along with future research directions. This review provides a theoretical framework for the application of natural polysaccharides as functional foods, nutraceuticals, or lead compounds in T2DM prevention and treatment.",

The gut-kidney axis has emerged as a key factor in cisplatin-induced AKI, with gut microbial imbalance contributing to inflammation and metabolic dysregulation. Astragalus polysaccharides (APS), the main bioactive constituents of Astragalus membranaceus, have shown potential in mitigating AKI, partly through modulation of the gut microbiota. Clinical sequencing data indicate that cisplatin treatment reduces short-chain fatty acid (SCFA)-producing bacteria (e.g., Faecalibacterium, Roseburia) and increases potentially pathogenic groups (e.g., Enterobacteriaceae), leading to alterations in SCFA, amino acid, and bile acid metabolism. This study integrates these findings with existing literature to propose a molecular-weight (Mw)-defined APS model targeting the gut-kidney axis. While high-Mw APS (>100 kDa) primarily act via microbial fermentation to restore SCFA production and gut barrier function, low-Mw APS (< 10 kDa) may exert direct anti-inflammatory and anti-apoptotic effects. Advanced gut-targeted delivery systems are also discussed as strategies to enhance APS bioavailability and colonic targeting. Understanding these Mw-dependent mechanisms is critical for developing APS as a precise adjunct therapy to prevent cisplatin-induced AKI and improve patient outcomes.",

Today, several clinical medications such as corticosteroids, aminoslicylates and immuno-modulators are available, but each one of them have their own side effects. Therefore, to overcome these limitations, we are moving toward herbal drug therapies. This review presents the emerging role of Cucurbitacin (Cu), a highly oxygenated tetracyclic triterpenoid compound found in a variety of Cucurbitaceae plants and known for its anti-inflammatory response. Unlike previous reviews which just focuses on single derivatives or isolated mechanisms, this review focuses on multi-target analysis of Cucurbitacin (Cu) derivatives- CuB, CuE, CuIIa, and CuIIb, their biosynthesis, structure-activity relationships (SAR), inflammatory pathway modulation, gut microbiota regulation, extracellular vesicle-associated microRNAs, and differentially expressed genes (DEGs). The preclinical evidences shows that these derivatives of Cu have capability to treat UC, by inhibiting the Inflammatory pathways such as NLRP3 inflammasome, NF-\u03baB, JAK2/STAT3, MAPK and EGFR, which results in decreasing the level of Inflammatory cytokines such as IL-6, IL-1\u03b2 and TNF-\u03b1. They also upregulates the SCFAs producing beneficial bacteria and downregulates the harmful bacteria, thereby restoring epithelial integrity. Notably, Cu \u2161a is associated with alteration in composition of protein and microRNA in extracellular vesicles. All these factors help in the treatment of UC. Although preclinical findings are encouraging, the current evidence is largely restricted to DSS induced animal models and the clinical validation in human is still lacking. Various challenges related to narrow therapeutic windows, poor bioavailability, and toxicity require resolution before clinical translation. This review find these translational gaps and proposes targeted research directions including nanoformulation strategies, pharmacokinetic profiling, and early-phase clinical evaluation.",
        "42297164": "ID: 42297164\nTitle: Seaweed polysaccharides as multifunctional biotherapeutics in modulating gut microbiome, metabolic disorders and beyond: A review.\nAbstract: Seaweed-derived polysaccharides-fucoidan, laminarin, alginates, ulvan, and carrageenan-are often described as promising prebiotics with potential to influence the gut-liver-brain axis. Resistant to upper gastrointestinal digestion, they reach the colon where gut microbiota ferment them into metabolites, chiefly short-chain fatty acids (SCFAs). These metabolites in turn modulate intestinal barrier integrity, immune and metabolic homeostasis, and inter-organ signaling. However, a critical caveat is that each polysaccharide type exhibits substantial structural variability in molecular weight, degree and position of sulfation, monosaccharide composition, and linkage pattern, depending on species, harvest time, and extraction method. This variability fundamentally alters fermentation kinetics and SCFA profiles, yet most studies treat these polysaccharides as uniform entities. This review critically synthesizes current in vitro and in vivo evidence and emphasizes that the therapeutic significance of seaweed polysaccharides lies in their microbiota-mediated, multi-organ actions rather than in isolated biological effects. In addition, we analyzed the main challenges for food and health applications, including variability in polysaccharide sources and extraction methods, limited bioavailability, pollution risk, and the lack of coordinated global regulations. Addressing these gaps is essential for translating promising biological activities into safe, standardized functional components and for developing these polysaccharides into functional ingredients that can modulate the gut-liver-brain axis.",

However, the bacterial factors involved in colonization of the gastrointestinal tract are not well understood. Here, we clarify the role of capsular polysaccharides (CPS) in Akkermansia (Akk) colonization. We show that Akkermansia species have multiple cps loci, with cps1 being the most conserved across species. We find that cps1 is regulated by phase variation via invertible genetic elements, leading to population diversity during growth in culture media, mice, and humans. An A. muciniphila mutant that cannot produce capsular polysaccharides successfully colonized the intestines of mice but showed a reduced ability to interact with the mucus layer. Additionally, this mutant tended to form biofilms and increased aggregation on abiotic surfaces and within the gastrointestinal lumen. Our findings suggest that the A. muciniphila capsule acts as a phase-variable regulator of colonization by balancing planktonic mucus-associated states and biofilm formation. Akkermansia muciniphila, a member of the human gut microbiota, is associated with improved metabolic and immune health. However, the bacterial factors that allow this organism to thrive in the intestine and interact with the host are not fully understood. We identify capsular polysaccharides as key regulators of A. muciniphila association with mucin-rich layers in the gastrointestinal tract and its proximity to the intestinal lining. Furthermore, capsule synthesis in Akkermansia is controlled by epigenetic switches; hence, a small but significant fraction of bacteria lack a capsule. These capsule-free bacteria cluster and are prone to forming biofilms. Therefore, capsular phase variation enables A. muciniphila to switch between different colonization states, underscoring the role of A. muciniphila glycans in adapting to the gut environment.",

This mini review systematically classifies these compounds, summarizes their mechanisms of action, and evaluates their current and potential applications in functional food development. It also identifies several critical gaps, for example: how structural properties (type, source, molecular characteristics) and non-short-chain fatty acid fermentation metabolites influence physiological outcomes, the challenge of maintaining stability and functionality during processing (heat and pH optimization), the need to investigate nano-carbohydrate systems and prebiotic delivery matrices for microbiota modulation, metabolite release, and bioavailability, and the optimization of resistant starch extraction and application to balance functional benefits with sensory quality and in vivo validation. Translational evidence gaps, regulatory frameworks, personalized nutrition, and microbiome-based therapeutics are also discussed as future priorities.

        "42316508": "ID: 42316508\nTitle: Macromolecular Organization in Lentinula edodes: Integrating Co-Occurring Bioactives for Structure-Function Relationships Across Gut Microbiota and Host Metabolism.\nAbstract: Diet-microbe-host interactions are increasingly recognized as properties of complex food matrices rather than the sum of isolated compounds. Lentinula edodes (shiitake) provides a chemically diverse system containing \u03b2-(1\u21923),(1\u21926)-glucans, heteropolysaccharides, phenolics, terpenoids, eritadenine, ergothioneine, and bioactive peptides. Evidence suggests that biological effects attributed to shiitake are better interpreted within the whole matrix rather than through reductionist, single-compound approaches. Key structural features-including \u03b2-glucan branching, molecular-weight distribution, conformational stability, and polysaccharide-phenolic interactions- shape microbial accessibility and downstream host responses. Here, macromolecular organization refers to the architecture and co-occurrence of these components across digestion and microbial transformation. Across experimental systems, shiitake polysaccharides are linked to shifts in gut microbial composition, including enrichment of butyrate-producing and mucin-associated taxa such as Faecalibacterium, Roseburia, Akkermansia, and Bifidobacterium. These changes are often accompanied by altered short-chain fatty acid profiles and related signaling pathways. In parallel, low-molecular-weight compounds, particularly eritadenine and ergothioneine, are associated with lipid metabolism and redox-related processes in preclinical and limited human studies. However, interpretation is constrained by variability in structural characterization, study design, and limited availability of structure-resolved human data. This review integrates evidence across biosynthesis, processing, microbial fermentation, and host responses, emphasizing context-dependent associations rather than causal claims. By positioning shiitake as a model system, it highlights the value of structure-guided frameworks and outlines directions to improve reproducibility and translational relevance in functional food science. These insights extend beyond shiitake and provide a framework for interpreting structure-function relationships in complex food systems.",

Corticosteroids remain the mainstay of asthma therapy; however, a substantial proportion of patients with severe disease develop steroid hyporesponsiveness, limiting therapeutic efficacy and increasing disease burden. Emerging evidence implicates the gut microbiome as a key regulator of systemic immune responses, with growing relevance to asthma pathogenesis and treatment responsiveness. In this study, we investigated whether gut microbiota dysbiosis contributes to steroid hyporesponsive lung inflammation and whether fecal microbiota transplantation (FMT) can restore steroid responsiveness. Using a steroid-hyporesponsive asthma model, we demonstrate that the disease is associated with significant gut microbial dysregulation, characterized by reduced microbial diversity and depletion of immunoregulatory taxa. FMT partially restored gut microbial diversity, normalized community structure, and selectively replenished beneficial commensal bacteria, including Akkermansia muciniphila and Faecalibacterium prausnitzii, while suppressing pathogenic taxa. Importantly, restoration of gut microbial balance was associated with attenuation of lung inflammation and improved steroid responsiveness. These findings support a functional gut-lung axis in steroid hyporesponsive asthma and identify modulation of gut microbiota as a potential therapeutic strategy. Incorporating microbiota-directed interventions such as FMT may represent a novel adjunct approach for the management of refractory steroid-hyporesponsive asthma.",

In recent years, the association between gut microbiota and COPD has attracted extensive attention from researchers. This study aimed to explore the current research hotspots, knowledge gaps, and future research trends in the field of gut microbiota and COPD. A comprehensive search of literature related to gut microbiota and COPD published between 2009 and 2025 was conducted using the Web of Science and Scopus databases. Bibliometric analyses were performed using VOSviewer, CiteSpace, and R software. The number of publications in this field showed a significant growth trend from 2009 to 2025, with the highest number of publications recorded in 2024. China and the United States were the leading contributing countries, and institutions such as the University of Technology Sydney made important contributions. The International Journal of Chronic Obstructive Pulmonary Disease served as the core publication platform in this field, and Hansbro, Philip M. was a key contributor. Research in this field involved keywords including gut-lung axis, inflammation, probiotics, bacteria, and short chain fatty acid, which revealed the core themes and trends of studies on gut microbiota and COPD. To our knowledge, this study presents the first quantitative bibliometric analysis of the field of gut microbiota and COPD. The core research hotspots identified include the characteristics of gut microbiota alterations in COPD patients, as well as the reciprocal interactions and underlying mechanisms between COPD and gut microbiota; microbiota intervention strategies have also emerged as an emerging research direction.

Co-formulation with Brassica rapa L. polysaccharide offers a promising strategy to enhance its functionality; however, the impact of different colloidal delivery systems on the encapsulation performance and subsequent biological fate of this mixture remains unclear. In this study, we systematically compared three spray-dried delivery platforms, including liposomes (LP-CP), sodium caseinate nanoparticles (SC-CP), and \u03b2-cyclodextrin inclusion complexes (CYC-CP), for encapsulating CP. Our results demonstrated that the carrier system critically determined encapsulation performance, with SC-CP exhibiting superior curcumin loading capacity (7.24%), curcumin thermal stability (82.87% retention at 95\u00a0\u00b0C), and favorable hygroscopicity profiles. Notably, SC-CP facilitated enhanced colonic accumulation in vivo, achieving a peak accumulation of 53.45% at 8\u00a0h post-gavage, representing a 15-fold increase compared to curcumin from unencapsulated CP. By integrating in vitro fermentation models with in vivo animal experiments and employing 16S rRNA sequencing alongside short-chain fatty acid (SCFA) analysis, we systematically elucidated the carrier-specific modulatory effects on the gut microbiota. In the in vitro fermentation system, SC-CP significantly promoted the production of acetate, propionate, and butyrate, while enriching butyrate-producing genera such as Lachnospiraceae_NK4A136_group. In the in vivo animal model, SC-CP intervention resulted in a 1.6-fold increase in cecal butyrate levels and a marked increase in the abundance of beneficial genera, including Akkermansia, demonstrating superior modulation of microbial community structure and metabolic function. Collectively, these findings establish that the selection of a colloidal carrier not only dictates the physicochemical stability of the curcumin-polysaccharide mixture but also governs its spatiotemporal distribution within the gastrointestinal tract and its prebiotic capacity to remodel the gut microecology. This study provides a theoretical foundation for the rational selection of delivery systems to maximize the functional efficacy of bioactive ingredients in functional food applications.",

Beyond bacteria, the intestinal mycobiome and virome, including bacteriophages, shape mucosal immunity and metabolism through partially overlapping but non-redundant pathways. In this Review, we synthesize rapidly expanding evidence that fungi, bacteria, and phages in the gut form an integrated network that may influence susceptibility, inflammatory tone, and therapeutic responsiveness across asthma, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and lung cancer via the gut-lung axis. We first summarize how cross-kingdom communities in the intestine are organized and interact, highlighting a tripartite framework centered on pathogen-associated molecular pattern-pattern recognition receptor (PAMP-PRR) circuits, the short-chain fatty acid (SCFA)-regulatory T-cell axis, and tryptophan-indole-aryl hydrocarbon receptor (AHR) signaling. We then compare how these shared axes are differentially perturbed across asthma, COPD, ARDS, and lung cancer, using these disorders as representative but non-sequential disease contexts along a conceptual gradient of immune-microecological disruption. Finally, we discuss how dietary modulation, pre-/pro-/postbiotics, mycobiome- and virome-targeted strategies, and phage-based approaches could be rationally combined to restore gut-derived immunometabolic circuits and improve respiratory outcomes. By integrating cross-kingdom ecology with mucosal immunology, this Review provides an integrative interpretive framework suggesting that gut microbiome-targeted strategies may help refine prevention, stratification, and adjunctive treatment approaches in selected respiratory disease contexts.",

Gut microbiota and its metabolites are crucial modulators of the \"gut-skin axis\" in atopic dermatogenesis. However, systematic investigations integrating microbiome and metabolome profiling in mild-to-moderate pediatric AD remain limited. To characterize gut microbiota and metabolic profiles in children with mild-to-moderate AD versus healthy controls, and to identify potential biomarkers and mechanistic pathways involved in disease pathogenesis. This single-center case-control study investigated 53 children diagnosed with AD and 16 healthy participants, and collected their fecal samples for microbial and metabonomic analysis. Mild-moderate pediatric AD patients exhibited significantly increased gut microbial richness and distinct \u03b2-diversity compared to controls (PERMANOVA, R\u00b2=0.025, P\u00a0=\u00a00.017). Bacteroidota was enriched while Actinomycetota was depleted in AD patients (P <\u00a00.05). At genus level, Parabacteroides and Klebsiella increased, whereas Bifidobacterium decreased in AD. Species-level analysis revealed enrichment of bacteroides_plebeius, bacteroides_thetaiotaomicron, bacteroides_xylanisolvens, and parabacteroides_merdae in AD. A combined biomarker panel (Bacteroidota, Parabacteroides, and four key species) demonstrated promising exploratory diagnostic potential (AUC\u00a0=\u00a00.941, accuracy 84.6%), although these results require external validation in larger independent cohorts. Spearman analysis showed correlations between gut microbiome and clinical severity indicators. Thermodesulfobacteriota, Actinomycetota, Bifidobacterium, and specific ruminococcus strains positively correlated with the severity of AD. Metabolomics identified 68 differentially accumulated metabolites, primarily involved in lipid metabolism and nucleotide metabolism. Bacteroides species showed significant positive correlations with isovaleric acid levels in microbiota-metabolite analyses. Mild-to-moderate pediatric AD is characterized by distinct gut microbiota dysbiosis and metabolic alterations involving lipid metabolism. Cross-sectionally identified microbial features show exploratory associations with AD status, but causal inference is not possible. These hypothesis-generating findings support further investigation of the gut-skin axis in AD development and provide a rationale for future interventional studies targeting the microbiome and metabolome.",

Wild populations are scarce, while artificially captive populations are also constrained by health issues such as digestive system diseases. To reveal the differences in gut microbiota between captive and wild forest musk deer from different geographical regions, fecal samples were collected from captive individuals in Nanyang, Henan (HN) and Gaoping, Shanxi (SX), as well as wild individuals in Baotianman, Henan (YS), with 5 samples per group. High-throughput 16S rRNA sequencing was employed to analyze the microbial community structure and function. The sequencing revealed Firmicutes, Bacteroidota, and Proteobacteria as the dominant phyla across all three groups, with Actinobacteriota exhibiting a significantly higher abundance in the YS wild group (11.13%) than in the HN (1.29%) captive and SX (6.12%) captive groups. There were no significant differences in \u03b1-diversity among the groups. However, \u03b2-diversity analysis (PCoA and NMDS) indicated a clear separation in microbial community structure between captive and wild groups, with some individuals in the SX captive group clustering with the wild group. LEfSe analysis identified 36 differential biomarkers: the YS wild group was enriched in genera including Bacillus, Arthrobacter, and Microbacterium, whereas the HN captive group was enriched in Bacteroides, Clostridium, and Eubacterium, while the SX captive group was enriched in Skermanella (genus) and Cytophagales (order). Functional prediction analysis revealed that the gut microbiota of the wild group was significantly enriched in the pathways of xenobiotics biodegradation and metabolism as well as lipid metabolism, whereas the captive groups showed higher activity in the translation and nucleotide metabolism pathways. This study reveals the impacts of rearing methods and geographical factors on the gut microbial community structure and function of forest musk deer. These findings can serve as a theoretical foundation for promoting healthy breeding of captive populations and as a reference for evaluating the health status of wild populations.",

A total of 384 one-day-old yellow-feathered broilers were randomly divided into 4 groups with 8 replicates per group and 12 birds per replicate. The control group and LPS group were fed a basal diet, while the L-Cit group and L-Arg group were supplemented with 1% L-Cit and 1% L-Arg in the basal diet, respectively. The experiment lasted for 27 days. On days 22, 24, and 26 of the experiment, broilers in the control group were intraperitoneally injected with 1 mg/kg body weight of saline, while those in the LPS group, L-Cit group, and L-Arg group were intraperitoneally injected with 1 mg/kg body weight of LPS. The results showed that no significant effect on growth performance of 21d broilers was observed among all groups (P > 0.05). Both the L-Cit group and L-Arg group significantly or extremely significantly increased the levels of T-AOC, SOD, IgG, and IgM (P < 0.05 or P < 0.01), and significantly decreased the levels of IL-6 and TNF-\u03b1 (P < 0.05 or P < 0.01). Hematoxylin-eosin staining and immunofluorescence analysis revealed that L-Cit alleviated intestinal villus atrophy and enhanced intestinal barrier integrity induced by LPS challenge. Notably, both L-Cit and L-Arg regulated the structure of the intestinal microbial community. L-Arg primarily promoted the abundance of beneficial bacteria such as g_Faecalibacterium and g_Barnesiella, whereas L-Cit significantly promoted g_Akkermansia to become the dominant genus and exert its function.",

Fermentation enhances food preservation and nutrient bioavailability, and supplies the host with probiotics, prebiotic substrates and postbiotic metabolites. These bioactive compounds can influence the oral and gut microbiota, modulate immune function and support metabolic resilience. Fibre-rich, plant-based fermented foods retain such components within structured matrices that enhance microbial viability and mucosal interactions more consistently than do fermented dairy foods. This Review explores how the fermented food microbiome affects the oral-gut axis via both transient microbial exposure and metabolite-mediated signalling. Drawing on clinical and preclinical evidence, we examine how fermented food intake alters resident microbiota and host physiology throughout the digestive tract. Despite growing evidence, the mechanisms through which fermented food might promote health remain insufficiently defined in humans owing to strain variability, inconsistency in microbial composition across fermented foods, heterogeneous clinical outcomes and regulatory ambiguity. Taking into account these limitations, we propose a roadmap to integrate the fermented food microbiome into precision nutrition as a feasible, personalized, diet-based strategy to promote health and prevent disease.",

Treating dementia is a crucial but often overlooked part of neurological care for the elderly. The gut microbiota plays an essential role in the bidirectional interaction between the gut and the brain. Growing evidence suggests that gut microbes, which can influence neural development, modulate neurotransmission, and affect behaviour, may contribute to the development and pathophysiology of various neurodevelopmental, neuropsychiatric, and neurological disorders like dementia. This underscores the need for new interventions targeting the gut-brain axis(GBA). This review highlights the role and application of phytochemicals in treating dementia by modifying the GBA. We outline the harmful relationship between dementia and microbial dysbiosis, focusing on abnormal tryptophan- kynurenine metabolism, impaired SCFA synthesis, disruption of the BBB, and altered microglial activation states. Nevertheless, the potential of different phytochemicals, such as flavonoids, alkaloids, terpenoids, and polyphenols, to enhance neuroprotective metabolite production, restore microbial balance, regulate inflammatory signalling (e.g., NF- \u03bab, Nrf 2, MAPK, and TLR 4), and improve synaptic plasticity via pathways like BDNF-CREB, is under investigation. Key bioactive compounds like berberine, resveratrol, and curcumin are being tested for their efficacy concerning molecular targets and outcomes in both preclinical and clinical models of cognitive decline. In addition to specific phytochemicals, probiotic and prebiotic synergistic approaches may enhance gut homeostasis and cognitive resilience, opening avenues for functional food- based treatments. Although promising, challenges to clinical application remain, such as low bioavailability, standardisation issues, and interindividual microbiome variability. This review emphasises prospects for precision nutrition and microbiome- targeted therapies in dementia, discusses translational barriers, and summarises recent data on phytochemical modulation of the GBA in dementia.",

The activity of unfermented and kombucha-fermented extracts was compared using tests for antioxidant activity, cytotoxicity, anti-inflammatory activity, antimicrobial activity, and transepidermal water loss (TEWL). Fermentation lasting 20\u00a0days (F20) significantly increased the bioavailability of compounds. Fermentation of root peels (F20) demonstrated the highest antioxidant capacity, achieving 65% inhibition of ABTS radicals. In anti-inflammatory tests, it most strongly inhibited IL-6, reducing the level of this cytokine from 5.31-fold (for the positive control with LPS) to only 3.61-fold. Furthermore, the F20 extract effectively improved the epidermal barrier by reducing TEWL and demonstrated potent antimicrobial activity, with a zone of inhibition for S. aureus of 18\u00a0mm. Cytotoxicity studies demonstrated good cell tolerance (viability above 100%) at low concentrations, while higher doses limited cell survival. The results confirm that fermented beet waste can be transformed into multifunctional, sustainable health-promoting raw materials.",

Its release into the environment raises major health concerns, particularly regarding metabolic disorders. After exposure, BPA leads to the accumulation of free BPA and its main metabolites, including bisphenol A-glucuronide (BPA-G), bisphenol A-disulfate (BPA-DS), and its chlorinated derivative, chlorinated bisphenol A-diglucuronide (BPA-DC). This study is aimed at evaluating the detoxifying effect of essential oil of Myrtus communis (EOMC) at 50, 100, and 200\u2009mg/kg, and vitamin E (100\u2009mg/kg), in male Wistar rats exposed to BPA (100\u2009mg/kg). Results showed a significant decrease in serum levels of BPA and its metabolites, along with increased urinary excretion, indicating enhanced biotransformation and elimination. BPA exposure also elevated fecal short-chain fatty acids (SCFAs) acetate, propionate, and butyrate, suggesting microbial dysbiosis and altered fermentation. EOMC and vitamin E treatments normalized SCFA profiles, demonstrating a modulatory effect on gut microbiota. The detection of \u03b1-pinene and 1,8-cineole in serum confirmed systemic bioavailability of EOMC and its role in detoxification. Overall, these findings highlight the protective effect of EOMC and vitamin E against BPA bioaccumulation and support their potential as natural detoxifying agents.",

Its aetiology and clinical presentation are very complex, resulting in an unpredictable course of the disease. The most important causes include smoking and environmental pollutants. However, upper airway microbiome dysbiosis has been linked with COPD severity. Through this review, we aim to compare the microbiome of the respiratory tract between its sites, and to see if there are any significant differences in the composition of the microbial flora of patients with COPD when compared to healthy individuals. While preparing this review, the PubMed database was searched using keywords such as bacteriome, COPD, exacerbation, and microbiome. Analysis of the airway microbiome shows that the three most abundant phyla are Firmicutes, Proteobacteria, and Bacteroidetes. The severity of the disease and the selected therapeutic methods influence the ratio of Proteobacteria and Firmicutes. It has been observed that a decrease in microbial diversity resulted in lower values of FEV1 in patients and could be related with COPD's progress and exacerbation events. While exacerbation cases need quick treatment, COPD's complex background makes it difficult to find a singular, microbial cause.",

Methods: An RSV-infected mouse model was established through intranasal inoculation. Lung pathological changes, viral RNA levels, lung index, and inflammatory cytokine levels were evaluated. Untargeted metabolomics and 16S rRNA gene amplicon sequencing were performed to characterize JYH-mediated alterations in pulmonary metabolites and the gut microbiota. Spearman correlation analysis was conducted to assess associations between differentially abundant bacterial genera and significantly altered metabolites. Results: JYH alleviated RSV-induced pulmonary histopathological injury, reduced viral RNA levels, decreased lung index and interleukin-6 (IL-6) levels, and increased interferon-\u03b3 (IFN-\u03b3) levels. Metabolomic profiling identified 46 differential metabolites, among which 26 showed a reversal trend following JYH administration. These metabolites were mainly enriched in pathways associated with the synaptic vesicle cycle, lysosomal function, and Forkhead box O (FoxO) signaling. Gut microbiota analysis showed that JYH increased microbial richness and diversity, whereas KEGG-based functional prediction indicated that the differentially abundant taxa were primarily involved in amino acid, carbohydrate, and nucleotide metabolism. Moreover, correlation analysis revealed significant associations between key bacterial genera, including Gemella, Sutterella, and CC_115, and differential metabolites such as pyridoxamine, uridine monophosphate (UMP), and argininosuccinic acid. Conclusions: JYH may protect against RSV-induced pneumonia by restoring pulmonary metabolic homeostasis and modulating gut microbiota composition. These findings provide new insights into metabolite-microbiota interactions underlying the anti-RSV activity of JYH.",

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPAR\u03b1/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.",
        "42352300": "ID: 42352300\nTitle: The Gut-Lung Microbiome Crosstalk and Pulmonary Disease.\nAbstract: Both the gut and the lungs possess a microbiome, a community of commensal bacteria, archaea, fungi, and viruses that perform important housekeeping functions in those organs. The colonic microbiome primarily ferments indigestible dietary fibers into essential short-chain fatty acids, synthesizes essential vitamins, regulates the mucosal immune system, and forms a protective barrier against pathogenic colonization. The lung microbiome maintains respiratory health primarily by regulating mucosal immunity, providing a physical barrier against invading pathogens, and producing beneficial metabolites. Several colonic microbiota metabolites, including the short-chain fatty acids acetate, propionate, and butyrate, together with the tryptophan metabolites indole-3-acetate and indole-3-propionate, secondary bile acids, and the polyamines spermidine and putrescine, are transported to the lungs via the gut-lung axis. These colonic microbiota biomolecules suppress lung inflammation, strengthen immune homeostasis, and reduce the severity of respiratory diseases. In contrast, lung microorganisms and their metabolites can travel to the gut via the gut-lung axis, influencing intestinal immune responses and potentially leading to an imbalance of gut microorganisms or dysbiosis. This means that respiratory diseases may lead to digestive issues, intestinal inflammation and chronic diseases. Here, we have reviewed this crosstalk and its impact on the principal pulmonary diseases: asthma, chronic obstructive pulmonary disease, cystic fibrosis, bronchogenic carcinoma, COVID-19, interstitial lung diseases, pneumonia, and tuberculosis. It is concluded that the gut microbiome plays a significant part in lung health and disease. Diet, tobacco smoking and electronic cigarette vaping all impact both the gut and lung microbiomes.",

While chronic inflammation, impaired iron absorption, and intestinal blood loss are recognized contributors, microbiome-mediated mechanisms influencing host iron availability remain insufficiently explored. Emerging evidence indicates that CD-associated dysbiosis is characterized by an increased abundance of siderophore-producing bacteria, particularly members of the Enterobacteriaceae family. Because siderophores are high-affinity iron-chelating molecules capable of competing with host iron acquisition systems and partially escaping lipocalin-2-mediated sequestration, their expansion may contribute to reduced luminal iron bioavailability. In this systematic review, we analyzed comparative microbiome studies published between 2016 and 2026 that directly evaluated microbial differences between CD and UC. CD microbiota consistently demonstrated enrichment in siderophore-associated taxa relative to UC. Based on these findings, we propose that microbiome-driven iron competition may represent an additional mechanistic contributor to the increased prevalence and persistence of anemia observed in CD. Although direct in vivo quantification of siderophore activity in IBD remains limited, the convergence of ecological, functional, and strain-level microbiome evidence supports a biologically plausible interaction between microbial iron-scavenging strategies and host iron metabolism.",

This systematic review (PROSPERO CRD420251131354) evaluates evidence from studies published between 2020 and 2026 assessing how nutritional and lifestyle interventions influence gut microbiota in children with obesity. Methods: A systematic search of PubMed, EMBASE and EBSCO identified 21 interventional studies involving children aged 5-18 years with obesity, with the last search conducted in April 2026. Interventions comprised prebiotics, probiotics, synbiotics, postbiotics, high-fiber diets, calorie-restricted dietary approaches, and lifestyle modifications such as physical activity. Microbiome outcomes were analyzed using 16S rRNA sequencing, quantitative real-time polymerase chain reaction (qPCR), or metagenomics. Risk of bias was evaluated using the RoB 2 and ROBINS-I (version 2) tools. Due to substantial heterogeneity in study design, participant characteristics, intervention types, and analytical methods, a meta-analysis was not feasible. Results: Across 21 studies, nutritional interventions included measurable but heterogeneous alterations in gut microbiome composition. Inulin supplementation was associated with a significant increase in alpha diversity and with higher relative abundances of Bifidobacterium, Blautia, Megasphaera, Subdoligranulum, and Eubacterium coprostanoligenes. Synbiotic supplementation increased Prevotella and Dialister and reduced the Firmicutes/Bacteroidetes ratio. High-fiber dietary interventions increased Faecalibacterium, Bifidobacterium, and Clostridium, while reducing Bacteroides, and were associated with shifts in metabolic pathways related to carbohydrate, lipid, and nucleotide metabolism. Calorie-restricted diets and combined diet-exercise interventions increased beneficial taxa such as Akkermansia muciniphila, improved microbial diversity, and correlated with favorable metabolic and anthropometric outcomes. Overall, nutritional and lifestyle interventions in pediatric obesity were associated with taxon-specific and context-dependent microbiome changes, rather than uniform restructuring. Conclusions: Nutritional interventions can modulate gut microbiota diversity, composition, and predicted function in pediatric obesity; however, the observed effects vary substantially across studies. The limited number of trials, small sample sizes, and methodological heterogeneity underscore the need for larger, standardized studies to better define clinical and therapeutic implications.",

Fermentation by lactic acid bacteria (LAB) increases its nutritional value compared to the unfermented beverage while improving the digestibility and bioavailability of essential nutrients via proteolytic enzyme activity. This study investigated the production of bioactive peptides in fermented chickpea water extract using ten bacterial strains isolated from plant and animal sources. The proteolytic activity of each strain was quantified using the trinitrobenzene sulfonic acid (TNBS) method, and the presence of proteolytic genes was confirmed via agarose gel electrophoresis. Peptides released during fermentation were identified through two-dimensional electrophoresis, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and tandem mass spectrometry. To predict the potential biological activities of the studied peptide sequences, a series of in silico analyses were performed using specialized bioinformatics tools. The identified peptides were predicted to exhibit antioxidant, antihypertensive, anticancer, antibacterial, antifungal, antituberculosis, and angiotensin-converting enzyme (ACE) inhibitory activities. Based on the results, L. fermentum SB-2 and L. sakei SD-8, were selected as promising candidates for bioactive peptide production in a chickpea water extract-based milk beverage and were subsequently applied in the beverage prototype.",

As a food-grade hydrophilic colloid, DDZ effectively improves the colloidal stability of the delivery system. Deamidation increased hydrophilic amino acids and surface negative charge. DDZ bound Q via static quenching with a higher binding constant (Ka = 2.25 \u00d7 103 L/mol) and more binding sites (n = 1.7561) than zein, along with stronger hydrogen bonding and hydrophobic interactions. Q@DDZ exhibited higher encapsulation efficiency (45.36-87.32%) and loading capacity (1.82-12.27%) than Q@zein, with a smaller particle size and better dispersibility. At 50.0 \u03bcg/mL Q, Q@DDZ showed 41.06% (DPPH) and 46.62% (ABTS) higher scavenging rates than free Q. It displayed excellent stability under acidic, high ionic strength, and thermal conditions (80 \u00b0C, 180 min). In simulated digestion, Q@DDZ delayed Q release in the oral and gastric phases and prolonged intestinal release, which indicated potentially improved bioavailability. This study provides mechanistic insights into deamidation-modified plant protein delivery systems for hydrophobic bioactives, offering new perspectives for the development of functional biopolymer gel materials.",

This study investigated the protective effects of low-molecular-weight fractions (<3 kDa) of the probiotic Limosilactobacillus fermentum CECT5716 (LMW-LF) in a murine model of experimental colitis. Male C57BL/6J mice were orally administered LMW-LF for 10 days prior to colitis induction with 3% dextran sodium sulfate (DSS) for 5 days. Colonic damage was assessed via the Disease Activity Index (DAI), histology, and immunofluorescence (Ocln and Ki67). Immune cell populations were analyzed by flow cytometry, while mucosal gene expression and gut microbiota composition were evaluated using RT-qPCR and 16S rRNA sequencing, respectively. LMW-LF administration significantly attenuated clinical symptoms and macroscopic colonic damage. Treatment restored epithelial barrier integrity by upregulating tight junction proteins (Tjp1) and mucin genes (Muc1-3) while normalizing DSS-induced epithelial hyperproliferation. Immunologically, LMW-LF reduced pro-inflammatory monocyte infiltration; downregulated Il6, Tnfa, and Ifng; and promoted an immunoregulatory phenotype by enhancing Ampk expression and partially restoring regulatory T cell (Treg) populations. Furthermore, LMW-LF reshaped the gut microbiota by increasing alpha diversity and promoting the enrichment of beneficial taxa, specifically Akkermansia muciniphila, which correlated with improved mucus layer preservation. LMW-LF is an active fraction acting across the host-microbiota axis. By integrating epithelial protection, immunomodulation, and microbial reshaping, it represents a promising dietary strategy for the management of Inflammatory Bowel Diseases.",
        "42359789": "ID: 42359789\nTitle: Mucin-derived sugars act as metabolic brakes controlling growth initiation in Akkermansia muciniphila.\nAbstract: Akkermansia muciniphila is a key member of the gut microbiota and plays important roles in host metabolism and health. In the colon, A. muciniphila extracts nutrients from oligosaccharide-rich mucin glycans that comprise the mucosa. However, this environment is complex and shaped by dietary inputs, microbiome metabolism, and mucin glycan composition varying across hosts, gastrointestinal regions, and physiological states. How strains of A. muciniphila integrate these nutrient signals into growth initiation and niche colonization remains unclear. Here, we compare physiological responses of a human- and mouse-derived strain of A. muciniphila, finding that dietary sugars differentially affect these isolates, suggesting host-associated tuning of metabolic capacity. In contrast, several mucin-derived sugars impose a conserved, concentration-dependent delay in growth initiation, implicating the lag phase as a critical metabolic checkpoint for growth. Genetic suppressor analysis identified sugar kinases and a component of the tricarboxylic acid cycle as genetically encoded control points linking glycan sugar exposure to the energy balance required for growth. These findings demonstrate that mucin-derived sugars function as both nutrients and metabolic stressors, regulating growth initiation. We propose that A. muciniphila employs metabolic \"brakes\" to coordinate growth with mucin composition, putatively linking host glycan landscapes to microbial physiology and ecological fitness within the mucus layer.",

The normal lung is not sterile, with a distinct microbial ecosystem that is spatially varied along the respiratory tract. The biogeography of the lung microbiome is balanced between microbial microaspiration from the oral-pharynx and clearance. The mouth is an important reservoir for respiratory pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, and Staphylococcus aureus, as well as oral microbes (Porphyromonas, Prevotella, Fusobacterium, etc.). Poor oral hygiene and periodontitis increase the bacterial load that can be aspirated, and the host produces pro-inflammatory components that enhance microbial virulence and compromize epithelial integrity. Both poor oral hygiene and periodontitis have been associated with pneumonia, particularly in hospitals and nursing home settings. Periodontitis may also facilitate viral pneumonia (including COVID-19) by altering receptor expression and immune function. Periodontitis correlates with COPD severity and exacerbation frequency through pathways involving matrix metalloproteinases and cytokines. Periodontitis also is associated with asthma and acute exacerbations. Inflammation shapes the lung microbiome by impacting microbial nutrient availability through vascular leakage, inducing changes to epithelial cells which facilitate bacterial adherence, and inducing the production of cytokines, leading to mucus overproduction, inhibition of phagocytosis, and enhancement of microbial pathogen virulence. Multiple biological pathways have been examined in\u00a0vitro that suggest how \"the oral-lung axis\" influences pneumonia, COPD, and asthma. Periodontal treatment and effective oral hygiene should be well integrated into medical care to prevent and manage respiratory diseases.",

Through microbial fermentation and thermal processing two mechanistically distinct pathways, garlic undergoes significant biochemical transformations that enhance the availability of bioactive compounds, including S-allyl-L-cysteine (SAC), polyphenols, and \u03b3-aminobutyric acid (GABA), which collectively contribute to improved antioxidant capacity and gut health. This comprehensive review examines the microbial ecology underlying garlic fermentation, the biochemical pathways that generate bioactive metabolites, and the mechanistic basis by which fermented garlic employed in the broader food fortification strategy or incorporated into fortified therapeutic food formulations targeting clinical malnutrition, may support nutritional recovery in the context of Environmental Enteric Dysfunction (EED), the dominant gut pathology underlying stunting and wasting in low- and middle-income countries (LMICs). Fermented garlic is a bioactive-dense nutritional adjuvant rather than a macronutrient source, its clinical relevance lies in potential enhancement of gut barrier integrity, reduction of mucosal inflammation, and support of micronutrient bioavailability, rather than direct caloric contribution. Preclinical evidence from animal models demonstrates improvements in intestinal morphology, metabolic parameters, and immune function, suggesting potential utility in nutritionally stressed populations. However, well-designed human clinical trials specifically examining fermented garlic in malnourished populations are currently underrepresented in the literature, and all translational implications discussed herein remain preliminary. Substantial research gaps persist regarding optimal dosage, long-term clinical safety, and standardization of fermentation protocols. This review identifies critical research priorities necessary to establish fermented garlic as a scalable, culturally acceptable food-based complementary intervention for vulnerable populations worldwide.",

Akkermansia muciniphila, a commensal bacterium has been reported to be depleted in individuals with IBD, although its precise role in intestinal inflammation remains unclear. This study examined the effects of A. muciniphila across multiple models of colitis, including dextran sulphate sodium (DSS)-induced colitis, the Mucin-2 knockout (Muc2-/-) model of spontaneous colitis, and Trichuris muris-mediated infectious colitis. In a DSS recovery model, treatment with pasteurized A. muciniphila reduced the severity of inflammation. However, when administered prior to DSS exposure, both live and pasteurized bacteria did not significantly reduce inflammatory markers, suggesting limited preventive effects. In T. muris-infected mice, supplementation with live A. muciniphila increased Th2 and anti-inflammatory cytokine responses, reduced parasite burden, and enhanced gene expression of the mucin Muc5ac. Additionally, both live and pasteurized A. muciniphila alleviated spontaneous colitis severity in Muc2-/- mice, indicating that these protective effects occur independently of Muc2. These findings expand understanding of the role of A. muciniphila in intestinal inflammation and highlight its potential as a therapeutic target for inflammatory intestinal disorders such as IBD.",

The microbiota-gut-brain (MGB) axis, particularly short-chain fatty acid (SCFA)-producing microbiota dysbiosis, has emerged as a conserved driver of neuroinjury pathogenesis. Natural food-derived polysaccharides have been explored as prebiotic substrates, but their clinical translation is hindered by poor target specificity, high interindividual heterogeneity, and low bioavailability. Engineered food-derived polysaccharides, as a next-generation precision prebiotic platform, enable rational tailoring of molecular fine structures via targeted physical, chemical, biological, and combinatorial modification technologies, aiming for strain-specific directional modulation of intestinal SCFA-producing microbiota and multi-pathway neuroprotection through the MGB axis. In this review, we systematically delineate the bidirectional regulatory mechanisms between SCFA-producing microbiota and neural homeostasis, dissect disease-specific pathological cascades driven by SCFA-producing microbiota dysbiosis, and discuss conflicting findings on the dual effects of SCFAs. We further propose a full-chain framework of the structure-activity relationship of engineered polysaccharides, dissecting core modification strategies, strain-specific targeting mechanisms, and a multi-dimensional efficacy evaluation system for these precision prebiotics. Additionally, we assess safety evaluation status, major global regulatory differences, and core clinical translation bottlenecks. Finally, we outline key unresolved challenges and propose a conceptual roadmap for AI-assisted rational design of precision prebiotics, personalized microbiota-adapted intervention strategies, and multicenter clinical translation directions. This review provides a mechanism-driven theoretical framework and practical guidance for developing engineered food-derived polysaccharides as precision nutrition interventions for neuroinjury-related disorders.",

Exposure to air pollution from sources such as biomass burning leads to a unique COPD phenotype. This phenotype mainly shows airway damage, with less emphysema than typical smoking-related phenotypes. Across various COPD phenotypes, airway epithelial barrier dysfunction is a basic pathological mechanism. This narrative review summarises the current available evidence on how different types of airborne pollutants, including particulate matter (PM), ozone (O3), diesel exhaust and microplastics, damage the airway epithelial barrier. The toxicity of fine PM with a diameter of \u22642.5 \u00b5m, one of its main constituents, largely depends on its chemical composition. Some metals or organic chemicals with redox properties can initiate oxidation reactions and induce pathologic responses. The main injury mechanisms are direct physical damage to apical junctional complexes, serious impairment of mucociliary clearance and induction of oxidative stress. Apart from these immediate harms, pollutants also create epigenetic modifications and disturbed epithelium-immune cell cross-talk, which breaks down the equilibrium of the airway epithelial barrier. These system-wide effects are exacerbated through the gut-lung axis, which aggravates local lung damage via microbiome dysregulation. We evaluate emerging therapeutic strategies that aim to restore barrier integrity, including antioxidants, natural compounds, inhibitors directing specific pathways (e.g. epidermal growth factor receptor (EGFR), NLR family pyrin domain containing 3 (NLRP3)) and microbiome modulation via probiotics. Protection and repair of the airway epithelial barrier offer a promising approach to reducing the onset and progression of pollution-related COPD in populations vulnerable to highly polluted environments.",

Although plant proteins are central to this transition, they remain limited by imbalanced amino acid profiles, reduced digestibility, and inferior techno-functional properties, restricting their nutritional equivalence. Recent studies have explored processing strategies to address these limitations; however, these approaches are often evaluated independently, with limited integration of structural mechanisms and phytochemical-protein interactions. This review presents a comparative and mechanistic synthesis based on cross-study evaluation, integrating protein structure, processing-induced modifications, and phytochemical-assisted interactions. Processing strategies including extrusion, fermentation, enzymatic hydrolysis, and pH shifting primarily enhance protein accessibility and reduce antinutritional constraints. In contrast, phytochemicals modulate protein conformation and interfacial behavior through both non-covalent and covalent interactions. Evidence across studies indicates that these effects are strongly concentration-dependent: moderate phytochemical interactions promote partial unfolding and improved functionality, whereas excessive interactions induce aggregation and reduce digestibility. Notably, the combined application of bioprocessing and phytochemical strategies yields greater improvements in solubility, emulsification, and bioavailability than individual approaches, although variability in protein source and processing conditions remains a key limitation. Overall, this review establishes a mechanistic framework linking protein structure, processing dynamics, and phytochemical interactions, highlighting concentration-dependent effects and synergistic strategies for improving plant protein functionality, while identifying variability and optimization challenges for future applications.",

Initially, ABCG2 was known for its role in multidrug resistance. ABCG2 has since been identified as a high\u2011capacity urate efflux pump, located at the apical membranes of renal proximal tubules, intestinal enterocytes and hepatic canaliculi. The present review covers the molecular structure, physiological functions and pathophysiological effects of ABCG2, with particular focus on the common Q141K (rs2231142) loss\u2011of\u2011function variant. The Q141K variant impairs protein stability and trafficking, reducing urate transport and increasing the risk of gout and cardiorenal comorbidities. The present review explores the central role of ABCG2 within the urate transportome, highlighting its contrasting and cooperative interactions with reabsorptive and secretory transporters, as well as its regulation by novel mechanisms, including the gut microbiome and microbial metabolites. These observations have significant clinical implications for pharmacogenomic approaches, as Q141K variant carriers exhibit a reduced response to uricosuric drugs. The present review also highlights emerging treatments that go beyond standard urate\u2011lowering therapies, including ABCG2 activators, microbiome modulators and gene\u2011editing techniques, offering a potential shift toward personalized gout prevention and treatment. Understanding the multifaceted role of ABCG2 is essential for developing targeted strategies to address the root cause of impaired urate excretion.",

However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17A+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.",

Although traditionally viewed as lower airway events, growing evidence suggests that AE-COPD may reflect broader pan-airway dysfunction involving both upper and lower respiratory compartments. This overview examines upper - lower airway crosstalk in AE-COPD across three domains: pan-airway inflammation, epithelial alarmin/cytokine networks, and the continuous airway microbiome. We discuss the coexistence of COPD with sinonasal inflammation, chronic rhinitis, and chronic rhinosinusitis, and their possible contribution to symptom burden, impaired quality of life, and exacerbation risk. We also review mechanisms linking upper and lower airways, including epithelial barrier dysfunction, impaired antiviral responses, innate immune activation, alarmin release, and microbiome-driven dysbiosis. Recognizing AE-COPD as a manifestation of pan-airway dysfunction may have relevant clinical implications. Systematic assessment of upper airway symptoms and comorbidities could improve phenotyping, risk stratification, and therapeutic targeting, particularly in frequent exacerbators. Future longitudinal and multi-omic studies are needed to validate upper airway biomarkers and determine whether targeted treatment of upper airway disease can modify COPD outcomes.",

Gastrodia elata polysaccharides (GEPs) represent a promising but mechanistically complex class of bioactive compounds with potential cardiovascular relevance. This review aims to examine the role of gut microbiota in mediating the biological effects of GEPs, with particular focus on resolving the bioavailability-efficacy paradox through host-microbe interactions. A narrative synthesis of recent literature was conducted, integrating data on microbiota-polysaccharide interactions, microbial fermentation processes, metabolite production, and downstream host signaling pathways. Due to limited systemic bioavailability, GEPs undergo extensive fermentation by gut microbiota, generating bioactive metabolites such as short-chain fatty acids and secondary bile acids. These metabolites modulate key host pathways including inflammation, oxidative stress, endothelial function, and lipid metabolism. Emerging evidence highlights the central role of the gut-heart axis in mediating these effects. The biological activity of GEPs is best understood within a microbiota-centered framework. This perspective provides new insights into polysaccharide pharmacology and supports the development of microbiome-targeted therapeutic strategies.",

Huanglian-Wendan Decoction (HLWDD) has been clinically used for IBD treatment; however, its underlying mechanisms remain unclear. In this study, a dextran sulfate sodium (DSS, 2.25%)-induced IBD mouse model was established to evaluate the therapeutic effects of HLWDD. The protective mechanisms were investigated in colon tissues of DSS-induced mice using ELISA, immunoblotting, histological, and immunohistochemical analyses. In addition, the impact of HLWDD on gut microbiota dysbiosis was analyzed using 16S rRNA sequencing. Antibiotic treatment was applied before DSS administration to deplete gut microbiota and verify the role of microbial modulation. Furthermore, the phytochemical constituents of HLWDD were characterized using liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (LC-QTOF-MS/MS). The results demonstrated that HLWDD markedly alleviated DSS-induced colitis, as evidenced by reduced body weight loss, rectal bleeding, colon shortening, and disease activity index (DAI) scores. Mechanistically, HLWDD suppressed inflammatory responses in colon tissues by inhibiting the TLR4/MyD88/NF-\u03baB and IL-6/JAK2/STAT3 signaling pathways, while enhancing epithelial barrier integrity through upregulation of ZO-1, Occludin, Claudin-1, and Mucin-2. In addition, HLWDD attenuated endoplasmic reticulum stress (ERS) and apoptosis by downregulating CHOP, phospho-eIF2\u03b1, cleaved caspase-3, and Bax, while increasing Bcl-2 expression in colonic tissues. Microbiota analysis revealed an increased abundance of beneficial bacterial genera such as Akkermansia and Escherichia-Shigella-related commensals, along with enrichment of beneficial bacterial families including Ruminococcaceae, Lachnospiraceae, and Verrucomicrobiaceae, whereas potentially harmful taxa such as Escherichia and Paraprevotella were reduced. HLWDD also increased the production of short-chain fatty acids (SCFAs), including acetate, butyrate, and isobutyrate, thereby promoting intestinal homeostasis. Importantly, the protective effects of HLWDD were largely abolished following antibiotic-mediated gut microbiota depletion, confirming the essential role of microbial modulation in its therapeutic action. Collectively, these findings suggest that HLWDD ameliorates IBD by regulating gut microbiota composition and function, thereby inhibiting colonic ER stress and apoptosis and restoring intestinal barrier integrity. This study provides mechanistic evidence supporting the potential clinical application of HLWDD as a novel therapeutic strategy for IBD.",

Adopting different processing methods may increase the nutritional components and bioavailability of whole grains. However, no study has systematically compared the different processing methods. Therefore, we systematically compared seven processing methods (raw grain, ultrafine pulverization, steaming, ultrasound, extrusion puffing, early sprouting (24\u00a0h), and sprouting (84\u00a0h) to evaluate their effects on foxtail millet nutritional quality and gut microbiota fermentation. In vitro simulated digestion and human fecal fermentation models were used to assess the release of nutrients, digestibility, and microbial metabolic response. The best effects were achieved using sprouting (84\u00a0h), which significantly increased the polyphenol content, \u03b3-aminobutyric acid (GABA), and phenylalanine ammonia-lyase (PAL) activity. The digestion products had high concentrations of short-chain fatty acids (particularly propionate and butyrate) during fecal fermentation, indicating enhanced prebiotic potential. PAL activity transiently increased with extrusion puffing; however, effective GABA accumulation did not occur. Notably, the abundance of Proteobacteria increased with sprouting (84\u00a0h), suggesting a potential risk of opportunistic bacterial proliferation. Collectively, sprouting (84\u00a0h) is the optimal processing method for improving both the nutritional quality and prebiotic potential of foxtail millet, achieving primary nutrient enhancement and secondary metabolic regulation.",

DC. attenuates Staphylococcus aureus-induced lung-gut injury in mice: explanatory pharmacological evidence related to its traditional dampness-resolving use.\nAbstract: Atractylodes lancea (Thunb.) DC. (A. lancea), a major botanical source of Atractylodis Rhizoma, has traditionally been used to dry dampness, strengthen the spleen, dispel wind-dampness, and regulate disorders associated with phlegm and impaired fluid transformation. However, the modern pharmacological basis linking these traditional indications to measurable lung-gut pathological changes remains insufficiently clarified. This study aimed to evaluate whether preventive administration of the ethanol extract of A. lancea (EEA) could attenuate Staphylococcus aureus-induced acute lung injury (ALI) in mice and to explore whether pulmonary edema, MUC5AC upregulation, intestinal barrier impairment, gut microbiota disturbance, and histidine metabolic remodeling may provide explanatory pharmacological evidence related to its traditional dampness-resolving and spleen-strengthening use. The chemical profile of EEA and its absorbed prototype constituents in plasma were characterized by UPLC-Triple TOF-MS/MS. Female BALB/c mice were orally administered EEA for 15 consecutive days and then challenged intranasally with Staphylococcus aureus. Lung injury, pulmonary edema, MUC5AC expression, inflammatory responses, MPO activity, hematological changes, intestinal barrier damage, and gut microbiota composition were evaluated using histopathological staining, lung wet/dry weight ratio, qRT-PCR, ELISA, blood cell analysis, and 16S rRNA sequencing. Untargeted metabolomics of serum and lung tissues, molecular docking, qRT-PCR validation of histidine metabolism-related genes, and correlation analysis were further performed to explore pathways associated with EEA intervention. A total of 29 compounds were identified in EEA, and six prototype constituents were detected in plasma after oral administration of EEA. Staphylococcus aureus challenge induced lung inflammatory injury characterized by increased lung index, elevated lung wet/dry weight ratio, inflammatory cell infiltration, pulmonary pathological damage, increased MUC5AC expression, increased IL-6 and TNF-\u03b1 levels, and decreased IL-10 levels. EEA attenuated these pulmonary abnormalities, reduced edema-related injury, decreased MUC5AC upregulation, and suppressed lung MPO activity. In parallel, EEA ameliorated intestinal pathological damage, restored mucin- and tight-junction-related gene expression, and partially modulated gut microbiota composition. Integrated serum and lung metabolomics consistently indicated that histidine metabolism was markedly perturbed in model mice and modulated by EEA intervention, as reflected by changes in L-histidine, histamine, N-methylhistamine, and methylimidazoleacetic acid. Molecular docking, qRT-PCR validation, and correlation analysis provided additional association-based evidence that histidine metabolic remodeling was correlated with the preventive effects of EEA. EEA attenuated Staphylococcus aureus-induced lung-gut inflammatory injury in mice, which was associated with its suppression of inflammatory responses, protection of intestinal barrier function, partial modulation of gut microbiota composition, and remodeling of histidine metabolism. These findings provide explanatory pharmacological evidence relevant to, rather than direct validation of, the traditional dampness-resolving and spleen-strengthening use of A. lancea.",

Conventional therapies, including mechanical debridement and local drug delivery, frequently fail to achieve adequate outcomes in advanced disease due to poor biofilm penetration, limited site-specificity, and the inability to modulate the host immune microenvironment. Quantum Dots (QDs) are semiconductor nanocrystals measuring 1-10\u2005nm, which possess unique size-dependent photoluminescence, high photostability, broad excitation profiles, and versatile surface functionalization, properties that have not yet been systematically evaluated in the context of periodontology. This review evaluates QD applications across four domains: diagnostics and bioimaging, targeted therapeutics and local drug delivery, tissue engineering and regeneration, and dental implantology. In diagnostics, QDs enable ultrasensitive detection of salivary and crevicular inflammatory biomarkers, real-time pathogen imaging, and integration into wearable point-of-care platforms. Therapeutically, they facilitate photodynamic antimicrobial therapy, stimuli-responsive drug release, and improved bioavailability of agents such as curcumin and metformin. In regeneration, they promote osteogenic stem cell differentiation and immunomodulation of the local inflammatory microenvironment. On implant surfaces, they enhance antibacterial activity and osseointegration. Despite this breadth, clinical translation remains constrained by cytotoxicity of heavy-metal-based variants, physicochemical instability in the oral environment, and the absence of long-term in vivo data and harmonized regulatory pathways. QDs especially emerging carbon-based variants represent a scientifically promising nanoplatform for precision periodontal care, but bridging the gap from bench to chair will require standardized synthesis, rigorous safety profiling, and well-designed translational studies.",

Emerging evidence suggests that gut microbiota dysbiosis may participate in HN pathogenesis by influencing uric acid metabolism, intestinal urate excretion, gut barrier integrity, microbial metabolite production, and gut-kidney immune crosstalk. However, the strength of evidence varies substantially across proposed mechanisms, with many findings derived from animal models, in vitro experiments, CKD studies, or human studies of hyperuricemia and gout rather than HN-specific clinical cohorts. This review summarizes current clinical and experimental evidence linking gut microbiota dysbiosis with HUA, gout, CKD, and HN, critically evaluates proposed mechanistic pathways, and discusses microbiota-targeted interventions including probiotics, prebiotics, dietary strategies, fecal microbiota transplantation, and metabolite-based approaches. Particular emphasis is placed on distinguishing association from causality and identifying translational gaps that should be addressed in future HN-specific studies.",

However, low bioavailability and unclarified therapeutic mechanisms impeded its deeply application. Plant-derived exosome-like nanoparticles offered a promising option for improving bioavailability and targeted delivery capability. To obtain dark tea-derived exosome-like nanovesicles (DTELNs) and clarify their material basis, investigate the therapeutic effects on hepatocyte carcinoma (HCC) and potential mechanisms. DTELNs were isolated by tangential flow filtration, TEM, NTA, nucleic acid & protein analysis system and LC-MS/MS were used to characterize their morphological characteristics and chemical composition. Orthotopic HCC model mice were established and employed for DTELNs' oral administration. Living imaging, H&E staining and biochemical assays were used to evaluate therapeutic effects. Untargeted metabolomic, 16S rRNA sequencing and cytometry by time-of-flight (CyTOF) were used to investigate the alteration of endogenous substances and immune features. Potential targets were explored by network pharmacology, protein-protein interaction, and verified by western blot. Finally, HCC patient-derived organoids were generated to evaluate the clinical applicability of DTELNs. DTELNs exhibited typical exosomal features, major components including flavonoids, phenolic acids, lipids, amino acids and their derivatives, and miRNAs. DTELNs markedly suppressed tumor proliferation, modulated gut microbial diversity, normalized liver-gut axis physiological homeostasis and enhanced immune responses. DTELNs distinctly downregulated the expressions of p-Akt, NF-\u03baB, Bcl-2, cyclin D1, upregulated the expressions of p-p53, PTEN, Bax, cleaved-caspase 3 and p21. DTELNs also exhibited potent inhibitory effect on HCC organoids. DTELNs demonstrated potent therapeutic efficacy against HCC. The mechanisms mainly involved directly modulating Akt-related signalling pathways, rebalancing gut microbiota and related metabolites, and further boosting anti-tumor immune responses.",

Conventional oral therapies are often limited by poor bioavailability and significant adverse effects. Herein, we developed an oral hydrogel for treatment of UC by electrostatic and hydrogen-bonding interactions of chlorophyll (Chl) and sodium alginate (SA) for the first time. The as-prepared Chl-SA hydrogel exhibited excellent biocompatibility and pH-responsive properties. In vitro assays showed that it reduced TNF-\u03b1 (271.51\u00a0pg/mL compared with 863.4\u00a0pg/mL in the LPS group), increased IL-10 (321.53\u00a0pg/mL compared with 91.66\u00a0pg/mL in the LPS group), and achieved 70% DPPH radical scavenging, confirming its potent anti-inflammatory and antioxidant activities. It exhibited robust therapeutic effects in a DSS-induced colitis mouse model after seven days of treatment, including ameliorating intestinal inflammation and restoring barrier integrity. These effects were achieved by mitigating oxidative stress, promoting mucosal healing and the expression of ZO-1 and occludin-1, as well as rebalancing the gut microbiota and restoring its richness and diversity. Importantly, given that hydrogels are generally known to offer advantages for patients with dysphagia over traditional oral formulations, the present study suggests that the Chl-SA hydrogel can offer therapeutic potential as a suitable oral dosage form for UC.",

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.",

To investigate the associations among dominant bacterial populations, key functional genes, and altered metabolites in cecal tissues and contents during E. tenella infection. Metagenomic analysis was first performed on cecal contents to identify the dominant bacterial communities, followed by metabolomic analysis of cecal tissues and contents. Correlation analysis was then conducted to evaluate the relationships among microbial communities, functional genes, and differential metabolites. Correlation analysis showed that increased potentially pathogenic genera were generally positively associated with upregulated metabolites and negatively associated with downregulated metabolites, whereas reduced commensal genera showed the opposite trend. Shared KEGG pathways co-enriched by differential metabolites and microbial functional genes were identified, mainly involving amino acid metabolism, transport systems, membrane-associated metabolism, and nucleotide metabolism. The metabolites linked to dominant bacterial communities were primarily enriched in pathways such as amino sugar metabolism, sialic acid metabolism, and glycerophospholipid metabolism. These findings reflected complex metabolic reprogramming and interactions between the host and pathogen, especially in cecal tissue repair, immune regulation, and metabolic competition with the pathogen. This study provided valuable insights into parasite-host interactions and laid a foundation for understanding the role of bacterial community-associated metabolites in cecal coccidiosis.",

Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, \u03b2-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1\u03b1 signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.",
        "42436034": "ID: 42436034\nTitle: Legume fermentation: Nutritional benefits and emerging applications.\nAbstract: Legumes are increasingly recognized as strategic plant-based ingredients due to their high content of proteins with good biological value, dietary fibers, minerals, oligosaccharides, and phenolic compounds. However, their broader use in food formulations is often limited by the presence of anti-nutritional factors (ANF) and other compounds that may negatively affect digestibility, technological performance, and sensory acceptability. In recent years, different technological and biotechnological strategies have been explored to enhance the nutritional and functional properties of legumes and legume-derived ingredients. Among these approaches, fermentation has emerged as a particularly effective and sustainable process widely applied in several traditional food systems. The use of selected lactic acid bacteria and fermentation processes inspired by sourdough technology has demonstrated a strong ability to reduce ANF, improve protein digestibility and nutrient bioavailability, and enhance the technological and sensory characteristics of legume flours and grains. In addition, fermentation contributes to improving food safety through the inhibition or transformation of spoilage microorganisms, pathogens, and toxic compounds. Beyond their direct consumption, fermented legumes are also key components of many traditional foods and can be successfully incorporated into innovative formulations of staple products, including baked goods and pasta, leading to foods with improved nutritional, functional, and shelf-life properties.",

Fermentation using lactic acid bacteria (LAB) and yeasts can eliminate antinutritional components and off-flavor compounds present in plant matrices while also generating beneficial metabolites. The interaction between fermentative microbes and plant substrates is dependent on plant matrices, microbial strains, and processing conditions.

Polysaccharides have been shown to enhance gut microbiota diversity, regulate microbial composition, and promote beneficial bacteria, thereby exerting immunomodulatory effects. Torreya grandis Fort. et Lindl polysaccharide (TGP) is a key bioactive component derived from Torreya grandis (TG). Understanding how gut microbiota dysbiosis in ALI influences pulmonary inflammation through the lung-gut axis, and whether TGP can ameliorate ALI pathology by modulating this axis, is of great interest. However, the specific mechanisms of TGP remain unclear. This study aimed to explore the therapeutic effects of TGP on ALI in mice via the lung-gut axis and its underlying mechanisms. The results showed that TGP alleviated both intestinal and lung injury, significantly improving intestinal barrier function by upregulating the expression of tight junction proteins, secretory immunoglobulin A (sIgA), and mucin 2 (MUC-2). TGP also modulated gut microbial communities in a favorable manner, fostering the proliferation of beneficial bacteria and elevating short-chain fatty acids (SCFAs) levels. Notably, in contrast to most polysaccharide studies that have primarily focused on acetate and butyrate, TGP markedly restored the levels of caproic acid and enriched SCFA-producing genera such as Norank_f_Muribaculaceae. These changes ameliorated immunothrombosis and restored immune cell subsets. Furthermore, TGP reduced the protein expression associated with the Toll-like receptor 4/nuclear factor-kappa B (TLR4/NF-\u03baB) signaling cascade. Collectively, these findings suggest that TGP may mitigate the inflammatory response in ALI mice by modulating the lung-gut axis, with its potential roles in caproic acid regulation and immunothrombosis amelioration offering new insights into lung-gut axis-targeted therapeutic strategies for ALI.",

COPD-associated gut dysbiosis suggests potential bidirectional interactions between the gut and lung, which may be mediated by circulating immune cells, gut microbiota-derived metabolites and systemic inflammatory mediators. Emerging evidence suggests that exercise may improve COPD-related symptoms and quality of life not only through direct cardiopulmonary adaptations but also by reshaping gut microbiota composition and metabolic function. Microbiota-derived metabolites, including short-chain fatty acids (SCFAs), secondary bile acids (SBAs) and indole derivatives, may act as key mediators linking exercise-induced microbial changes to pulmonary immune regulation, inflammatory signalling, oxidative stress and epithelial barrier integrity. However, current evidence remains fragmented, and the mechanisms by which exercise-responsive microbial metabolites influence COPD-related pulmonary inflammation, barrier dysfunction and immune homeostasis have not been fully clarified. This review synthesises evidence from human studies, animal models and mechanistic investigations to clarify the relationship among exercise, gut microbiota and COPD, with a focus on how exercise-responsive microbial metabolites may contribute to improved pulmonary health. By integrating current evidence within an exercise-gut-lung axis framework, this review provides a mechanistic basis for developing microbiota-targeted exercise strategies for COPD prevention and management.",

Short-chain fatty acids (SCFAs) serve as central immunomodulatory metabolites mediate the crosstalk between the gut and lung. Traditional Chinese medicine (TCM), with its holistic approach, shows promise in restoring gut-lung balance and alleviating respiratory inflammation by modulating gut microbiota and SCFA metabolism. To elucidate the protective role and mechanism of SCFAs in ALI and ARDS via the gut-lung axis. Meanwhile, to evaluate the therapeutic potential of TCM in treating ALI by modulating the gut microbiota and enhancing SCFA production. A comprehensive literature search was conducted across PubMed, Ovid-Embase, Web of Science, and CNKI databases (2010-2025). Keywords included \"short-chain fatty acid\", \"gut microbes\", \"acute lung injury\", \"traditional Chinese medicine\", and related terms. The search focused on preclinical and mechanistic studies investigating SCFA signaling, gut microbiota remodeling, and the therapeutic effects of herbal compounds or their active constituents in ALI/ARDS models. This review identified acetate, propionate, and butyrate as key mediators that protect against ALI through distinct mechanisms, including anti-oxidation, anti-inflammation, immunomodulation, apoptosis reduction, airway tight-junction protection, and regulation of intestinal homeostasis. In addition, 9 bioactive components, 5 single-herb extracts, and 4 Chinese herb formulations were found to ameliorate ALI by enriching SCFA-producing bacteria, such as Akkermansia, Lactobacillus, and Lachnospiraceae, thereby elevating systemic and local levels of acetate, propionate, and butyrate. SCFAs represent critical molecular mediators of the gut-lung axis, and their modulation by natural products offers a promising microbiota-centered strategy for ALI treatment. This microbiota-centered strategy holds great promise for ALI precision medicine.",

Blueberries (Vaccinium spp.) contain substantial amounts of anthocyanins and other neuroactive polyphenols that may confer neuroprotective effects. We summarize the literature published between 2016 and 2025 to examine how the bioactives in blueberries affect symptoms relevant to children with diagnosed neurodevelopmental or emotional-behavioral disorders, including ADHD, mood problems, and cognitive difficulties. Mechanistically, anthocyanins appear to modulate gut microbial composition, modulate neuroinflammation and alleviate oxidative stress via the Nrf2 pathway, and support synaptic plasticity and neurogenesis. Clinical trials, although limited in number and sample size, have reported modest improvements in mood and verbal memory in typically developing children and adolescents, with some gains in attention and executive function. However, direct trials in children with diagnosed neurodevelopmental or emotional-behavioral conditions remain scarce. There are substantial hurdles to translating these findings. Anthocyanins have poor physicochemical stability and low bioavailability, and routine food processing degrades their activity. Emerging solutions such as green extraction from agricultural by-products, colon-targeted microencapsulation, and zero-waste engineering could address these limitations. Rigorous randomized controlled trials in children with diagnosed neurodevelopmental or emotional-behavioral disorders are essential, as are advances in food engineering. Both are needed to move blueberry-based interventions from the laboratory to application.",

Oral nitrate-reducing bacteria convert dietary nitrate into nitrite, which can subsequently be reduced to nitric oxide, a signaling molecule associated with vascular tone, endothelial function, platelet activity, and blood pressure regulation. Disruption of this pathway has been associated with reduced nitric oxide bioavailability and impaired vascular responses. Methods: This narrative review summarizes current evidence regarding the relationship between the oral microbiome, nitrate metabolism, and cardiovascular function. Relevant literature was identified through searches of PubMed/MEDLINE and Google Scholar up to May 2026. Evidence from mechanistic, observational, and interventional human studies was reviewed and synthesized thematically. Results: Available evidence suggests that oral nitrate-reducing bacteria may influence nitric oxide bioavailability and vascular function. Studies have reported associations between oral microbiome disruption and changes in blood pressure, endothelial responsiveness, plasma nitrite concentrations, and other surrogate cardiovascular markers. However, findings remain heterogeneous and are influenced by factors such as diet, oral hygiene practices, smoking status, medication use, oral health, and underlying cardiometabolic conditions. Most studies are limited by small sample sizes, short intervention durations, and reliance on surrogate outcomes rather than major cardiovascular events. Conclusions: The oral microbiome may influence cardiovascular health through its role in nitrate metabolism and nitric oxide bioavailability. However, current evidence is largely limited to surrogate vascular outcomes, while data on major cardiovascular events remain scarce. Further longitudinal and interventional studies are needed to clarify causality and evaluate microbiome-targeted interventions.",

Lycium ruthenicum anthocyanins (LRACN) exhibit antioxidant and anti-inflammatory activities, but their effects on RP and the associated systemic mechanisms remain unclear. In this study, a mouse RP model was established by 15\u202fGy localised chest irradiation, and LRACN was administered orally before and after irradiation. Protective effects were evaluated using histopathology, inflammatory cytokines, and oxidative stress indices. Potential mechanisms were explored by integrating 16S rRNA sequencing, non-targeted serum metabolomics, metabolite-based target network analysis, transcriptomics, and single-cell RNA-seq. Compared with the model group, high-dose LRACN reduced injury score, collagen volume fraction, tumour necrosis factor-\u03b1, and malondialdehyde in the lung tissue by approximately 55%, 58%, 45%, and 44%, respectively. Multi-omics profiling revealed that LRACN partially restored radiation-disrupted gut microbial taxa, including Dubosiella, Ligilactobacillus, and Akkermansia, and reversed radiation-induced disturbances in serum purine and glycerophospholipid metabolism. Correlation analysis linked LRACN-responsive gut taxa and circulating metabolites with RP-related pathological, inflammatory, and oxidative indices. Integrated pathway analysis and western blotting suggested that the protective effect of LRACN was associated with reduced PI3K and Akt phosphorylation in lung tissue. These findings indicate that LRACN mitigates early RP in mice, and gut microbiota-associated metabolic remodelling may contribute to its protective effects.",

Current treatments, from small-molecule drugs to systemic anti-tumor necrosis factor-alpha (TNF-\u03b1) biologics, are frequently limited by off-target immunosuppression, heightened infection risk, and poor mucosal bioavailability. Engineered probiotic-based live biotherapeutics offer a compelling alternative by enabling localized drug production within the inflamed intestine. We engineered Escherichia coli Nissle 1917 (EcN) to secrete the anti-TNF-\u03b1 nanobody MT1, creating the streamlined, single-strain platform EcN-MT1. Five signal peptides were screened, and plasmid-based and CRISPR-Cas9-mediated chromosomal integration strategies were compared. Structural modeling and molecular dynamics simulated MT1-murine TNF-\u03b1 (mTNF-\u03b1) binding. Binding affinity and anti-inflammatory activity were assessed by ELISA and in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Therapeutic efficacy was further evaluated in a dextran sulfate sodium (DSS)-induced murine colitis model by assessing body weight, disease activity index (DAI), colon length, histopathology, colonic pro-inflammatory cytokines, and 16S rRNA gut microbiota profiling. Among the tested signal peptides, \u03b1-hemolysin (HlyA) achieved highest secretion (4.6\u00a0mg/L), and the plasmid-based strain markedly outperformed genomic integrants without impairing growth. Simulations confirmed stable complementarity-determining regions (CDR)-mediated binding, consistent with the high affinity (EC50 27.9\u00a0nM) and potent suppression of LPS-induced mRNA expression of Tnf and interleukin-1\u03b2 (Il1b) in macrophages. In the DSS-induced murine colitis model, oral administration of EcN-MT1 significantly attenuated weight loss, improved DAI scores, and preserved colon length. Histopathological analysis revealed reduced mucosal ulceration, crypt loss, and immune cell infiltration, accompanied by downregulated colonic Tnf and Il1b mRNA. Notably, EcN-MT1 treatment restored gut microbial diversity, corrected dysbiosis, and enriched beneficial taxa linked to butyrate production, barrier enhancement, and anti-inflammatory effects. This study establishes EcN-MT1 as a potent, orally deliverable live biotherapeutic that achieves localized TNF-\u03b1 neutralization while concurrently promoting microbial and mucosal homeostasis, offering a novel and translatable strategy for IBD treatment.",

In our previous study, a galU-deleted clinical P. aeruginosa was found to exhibit increased susceptibility to polymyxins. The galU gene plays an important role in the biosynthesis of lipopolysaccharide (LPS) O-antigen. Here, we systematically evaluated the effects of galU deletion on the phenotype and virulence of P. aeruginosa PAO1. A galU deletion mutant was successfully constructed in P. aeruginosa PAO1 by CRISPR/Cas9, and the complementation was accomplished by pUCP18 plasmid carrying wild-type galU. The changes in phenotype, virulence, and pathogenicity were systemically studied. The results revealed that knockout of galU led to the loss of O-antigen, which affected growth, virulence, and pathogenicity through various ways in P. aeruginosa, and significantly affected the susceptibility of P. aeruginosa to polymyxins. Mechanism study suggested the involvements of quorum sensing, Entner-Doudoroff pathway, and tyrosine metabolism on bacterial virulence and antibiotic susceptibility changes after galU deletion. galU and the related pathways may serve as effective targets for the treatment of P. aeruginosa infection, providing a theoretical basis for the development of novel antibacterial drugs.",

Diarrhea was induced in ICR mice using senna leaf extract. Mice received aqueous extracts of lotus seed, jujube, or longan aril for treatment. Intestinal motility was assessed through fecal consistency scoring and the charcoal propulsion test. Colon tissues were collected for histopathological examination using H&E staining, as well as immunohistochemical and Western blot analyses of aquaporin 3 (AQP3) and sodium-hydrogen exchanger 8 (NHE8). Gut microbiota composition was analyzed via 16S rRNA sequencing. All three herbal interventions significantly reduced the loose stool rate and diarrhea index (p\u202f<\u202f0.05), inhibiting small intestinal hypermotility. Histological analysis revealed an increase in goblet cell numbers and improved crypt architecture in the colon. Immunohistochemical evaluation indicated downregulation of AQP3 and upregulation of NHE8 expression, which was confirmed by Western blot analysis. 16S rRNA sequencing demonstrated that all treatments restored \u03b1-diversity (Shannon index, p\u202f<\u202f0.05). \u03b2-diversity analysis revealed that longan aril induced a more extensive reshaping of gut microbial community structure compared to lotus seed and jujube, which exhibited a \"phased\" restoration. The relative abundance of potential pathogens (e.g., Akkermansia muciniphila, Citrobacter spp.) significantly decreased, while beneficial short-chain fatty acid-producing bacteria (e.g., Blautia coccoides, Faecalibaculum rodentium, Alloprevotella rava) were enriched. Unique protective taxa, such as nitrogen-fixing Azospirillum and antioxidant Deinococcus, emerged in specific treatment groups. Lotus seed, jujube, and longan aril synergistically alleviated diarrhea via multiple pathways, including modulation of gut microbiota structure, repair of barrier function, balance of water-electrolyte metabolism, and inhibition of intestinal hypermotility.

Growing evidence indicates that MNPs may affect interconnected physiological systems, particularly the gut-liver-brain axis, which integrates metabolic, immunological, and neuroendocrine responses. This review summarizes current knowledge on the effects of MNPs on the gut-liver-brain axis based on animal studies, with emphasis on mechanisms of toxicity and inter-organ communication. Available findings indicate that the gastrointestinal tract is the primary site of interaction, where MNPs induce intestinal barrier disruption, oxidative stress, immune activation, and gut microbiota dysbiosis. These alterations may promote endotoxemia and inflammatory signaling, contributing to hepatic metabolic disturbances, mitochondrial dysfunction, and hepatocellular injury. In parallel, MNPs may affect the central nervous system through neuroimmune responses, altered neurotransmission, blood-brain barrier dysfunction, and gut-brain signaling disturbances. Oxidative stress, chronic inflammation, and disrupted inter-organ communication appear to represent central mechanisms underlying MNPs toxicity. Nanoplastics, due to their higher bioavailability and ability to cross biological barriers, exhibit particularly strong toxic potential. Overall, current evidence supports a systems-level view of MNPs toxicity and highlights the importance of integrative approaches for improving environmental and health risk assessment.",

High-resolution metaproteomics was applied to quantify microbial and host proteins, integrating functional annotation, differential expression, and weighted gene co-expression network analysis (WGCNA). We observed an acute, generalized decline in microbial diversity at Day 2 across both groups, indicative of a physiological response to surgical stress. Crucially, MI-specific divergence emerged during the subacute phase (Day 7) and persisted into recovery (Day 14). At Day 7, functional perturbations peaked in the MI group, significantly involving carbohydrate metabolism, nucleotide biosynthesis, and oxidative stress pathways, accompanied by taxonomic shifts including the depletion of Akkermansia and enrichment of Odoribacter and Muribaculum. Concurrently, host-derived proteins displayed time-dependent alterations in lipid catabolism and redox regulation. WGCNA revealed co-regulated protein modules linked to MI status and the recovery phase, reflecting highly synchronized host-microbiome responses. This time-resolved metaproteomic study demonstrates that following initial surgical stress, MI triggers dynamic, stage-specific alterations in gut microbial function and coordinated host responses, providing mechanistic insights into the gut-heart axis and suggesting potential microbiota-targeted strategies to promote post-MI recovery.",

This review critically examines recent evidence on the interactions between FDBPs and the immune system, with particular emphasis on macrophages, lymphocytes, and cytokine production. Peptides derived from dairy, egg, marine, and plant proteins have been shown to influence key immune functions. In macrophages, FDBPs may enhance phagocytosis and proliferation, and modulate M1/M2 polarization. Their effects on cytokine production are highly context-dependent: in resting cells, many peptides stimulate pro-inflammatory mediators such as TNF-\u03b1, IL-6, and nitric oxide, whereas in activated macrophages they may suppress these same mediators and promote IL-10 expression. In lymphocytes, FDBPs can stimulate proliferation and influence CD4+ T-helper cell differentiation, often shifting responses away from Th2-mediated allergy-associated pathways towards Th1 and regulatory T-cell-mediated tolerance. These effects are linked to interactions with cell surface receptors, including TLRs and to modulation of intracellular NF-\u03baB and MAPK signaling pathways. This review also evaluates the methodological limitations in peptide generation, purification, and experimental modeling that contribute to inconsistent findings across studies. Finally, major knowledge gaps are identified, including the need for more human clinical trials, a deeper understanding of peptide bioavailability, and the role of the gut microbiota as a potential intermediary. Standardized, physiologically relevant models will be essential for translating the immunotherapeutic potential of FDBPs into practical applications.",

Vitamin B12 (VB12) deficiency, which is highly prevalent in patients with diabetes, has been strongly associated with cognitive decline, hippocampal atrophy, and white matter injury. Emerging evidence suggests that VB12 plays a critical role in maintaining one\u2011carbon metabolism, mitochondrial function, and redox homeostasis. Mechanistically, VB12 deficiency promotes homocysteine accumulation, disrupts the S-adenosylmethionine/S-adenosylhomocysteine balance, impairs mitochondrial oxidative phosphorylation, and enhances oxidative stress, thereby driving pro-inflammatory microglial activation and sustained neuroinflammation. In addition, gut microbiota dysbiosis, particularly reduced abundance of Akkermansia muciniphila and other VB12-producing bacteria, may further impair VB12 bioavailability and aggravate neuroinflammation through the gut-brain axis. This review summarizes current evidence linking VB12 deficiency to microglial immunometabolic remodeling in DCI and discusses the therapeutic potential of targeting VB12 metabolism and gut microbial ecology for preventing diabetes-related cognitive decline.",

A total of 319 COPD patients from Changzhi People's Hospital (May 2020-March 2024) were consecutively enrolled and divided by sputum volume and characteristics into a high mucus secretion group (n=173) and a non-high mucus secretion group (n=146). Patients were randomly assigned to training (80%) and testing (20%) sets. Airway microbiome structure was analyzed via 16S rRNA sequencing. From clinical and microbiome data, 70 features were extracted. Six machine learning algorithms (SVM, KNN, RF, BN, GBDT, NN) were used to build classification models. Feature selection employed filtering methods, and hyperparameters were optimized by 10-fold cross-validation. Model performance was assessed using sensitivity, specificity, accuracy, and AUC. The CMH group and the non-CMH group differed significantly in a number of factors, including age, the length of the disease, and pulmonary function indices, according to a comparison of baseline patient data. Analysis of airway microbiome characteristics revealed that the CMH group had significantly lower observed ASVs and Shannon indices (p<0.001), along with significant enrichment of potentially pathogenic bacterial genera such as Haemophilus and Pseudomonas. Following feature selection, disease duration, Haemophilus abundance, history of AECOPD, Pseudomonas abundance, and predicted FEV1% were identified as significant predictive factors. With a sensitivity of 0.867, specificity of 0.789, PPV of 0.805, NPV of 0.855, and AUC of 0.911, the Bayesian Network (BN) model outperformed the other six machine learning models on the testing sets; its generalization ability was significantly superior to other algorithms such as SVM and RF. CMH in COPD is linked to airway dysbiosis and pathogen enrichment. The BN model effectively identifies this phenotype with strong generalization ability.",

Among them, Salicornia europaea L. is a coastal succulent whose adaptation to hypersaline environments shapes a distinctive phytochemical profile of pharmacological interest. This narrative review integrates current evidence on the bioactive composition, mechanistic activities, and translational relevance of S. europaea and related Salicornia species. Their secondary metabolome includes flavonols, isorhamnetin glycosides, hydroxycinnamic acids, oleanane-type triterpene saponins, fermentable polysaccharides, carotenoids, and a mineral-rich ionic matrix. Reported activities span antioxidant, anti-inflammatory, vascular-protective, anti-adipogenic, glycaemic-modulating, antimicrobial, and microbiome-related effects, mediated through pathways involving NF-\u03baB, PPAR-\u03b3, endothelial nitric oxide signalling, and short-chain fatty acid production. Beyond its individual phytochemical components, the matrix as a whole may also support sodium-reduction strategies in food formulation, providing a complementary nutritional rationale for its incorporation as a functional ingredient. Despite a coherent body of mechanistic and preclinical findings, clinical evidence remains limited, particularly regarding long-term efficacy, dose standardisation, and bioavailability in humans. Future work should prioritise adequately powered intervention trials and standardised characterisation of marine halophyte bioactives to clarify their evidence-based role in functional food development and future precision nutrition applications.",
        "42508778": "ID: 42508778\nTitle: Ionic liquid pretreatment modulates the composition of individual corn bran feruloylated oligosaccharide and the mucin O-glycanases regulation activity.\nAbstract: Feruloylated oligosaccharides (FOs) are bioactive conjugates that exhibit promising synergistic effects on gut microbiota modulation and intestinal barrier protection, yet their efficacy is highly structure-dependent. This study developed a synergistic strategy combining ionic liquid (IL, 1-butyl-3-methylimidazolium chloride) pretreatment with xylanase hydrolysis to selectively produce feruloylated arabinoxylobiose (FAX2) and feruloylated arabinoxylotriose (FAX3) from corn bran. The IL-pretreated FOs (FOsA) achieved a FAX3/FAX2 ratio of 4.86, which was 2.16-fold higher than that of the non-pretreated group (FOsB). Although in vitro assays confirmed that FOs were not directly utilized as a carbon source by Akkermansia muciniphila (A. muciniphila), both FOsA and FOsB significantly modulated its mucin-degrading enzyme activities (p\u00a0<\u00a00.05). Specifically, both fractions increased sialidase activity while reducing \u03b1-N-acetylglucosaminidase and \u03b2-galactosidase activities. Notably, FOsA, with a higher FAX3/FAX2 ratio, exhibited significantly stronger inhibition of exo-\u03b1-L-fucosidase activity than FOsB (p\u00a0<\u00a00.05). These findings demonstrate that FOs act as effective modulators of A. muciniphila enzymatic functions rather than metabolic substrates, and that their fine structural composition critically influences their regulatory potency on mucin-degrading enzymes, with potential implications for maintaining intestinal mucus barrier integrity.",
        "42509267": "ID: 42509267\nTitle: Unique adaptations in sulfatases underpin colonic mucin degradation by Akkermansia muciniphila.\nAbstract: Excessive foraging of colonic mucin glycans by gut bacteria is associated with diseases such as inflammatory bowel disease. Although Akkermansia muciniphila is an important mucin degrader, the role of carbohydrate sulfatases that facilitate digestion of these heavily sulfated glycans remains unclear. Combining in vitro digestion assays, proteomics and structural biology, we show that A. muciniphila sulfatases, such as Amuc1755 and Amuc0953, have rare adaptations targeted towards known sulfated mucin structures. They show larger degrees of modularity, including a previously unknown mucin-binding domain. When grown on colonic mucin substrates, glycoproteins of reduced size were important for the growth of A. muciniphila. Further mutational analysis and localization studies revealed that desulfation of N-acetyl-D-glucosamine was periplasmic, while desulfation of D-galactose occurred extracellularly and in the periplasm. These data improve our understanding of contexts for the positive health correlations of A. muciniphila while metabolizing colonic mucin as its sole carbon source.",
        "42509759": "ID: 42509759\nTitle: Mulberry, Gut Microbiota and Gut Functionality: Effects Shaped by Raw Material and Processing Methods.\nAbstract: Mulberry species (Morus spp.) provide phytochemically distinct plant materials in which leaves are typically characterized by high levels of iminosugars (notably 1-deoxynojirimycin), flavonols/flavones, and polysaccharides, whereas fruits-especially Morus nigra-contain substantial amounts of anthocyanins alongside other phenolic compounds and polysaccharides. Importantly, the composition and biological properties of mulberry-derived products depend not only on species and plant part (leaf vs. fruit), but also on preparation and processing variables, including drying, maceration, fermentation, and extraction, or fractionation strategy (e.g., aqueous vs. hydroalcoholic extracts or enriched fractions). Such technological factors may substantially influence the chemical composition, bioavailability, and functionality of mulberry-derived preparations and thereby modify their interactions with gut microbiota and host metabolic processes. Available preclinical studies indicate that mulberry leaf- and fruit-derived preparations can affect gut microbial composition or activity in experimental models of metabolic dysfunction. Reported findings frequently include enrichment of microbial taxa commonly regarded as beneficial, such as Bifidobacterium, Lactobacillus, and Akkermansia, normalization of dysbiosis-associated microbial patterns, and increased production of short-chain fatty acids, particularly acetate, propionate, and butyrate. These microbial changes are sometimes observed alongside improvements in metabolic parameters such as glucose regulation, lipid profile, adiposity, or inflammatory markers. However, reported responses differ across plant parts, species, and preparation approaches, indicating that phytochemical composition and processing strategy are likely to influence biological outcomes. Interpretation of the current evidence is limited by the predominance of non-human studies and by incomplete or inconsistent reporting of extract composition, processing conditions, and standardization procedures. These factors reduce comparability between studies and complicate mechanistic interpretation of microbiome-related effects. Overall, existing preclinical data support the possibility that mulberry-derived preparations may influence metabolic health through microbiota-associated pathways shaped by both botanical origin and preparative technology. Well-designed human intervention studies using chemically characterized and standardized preparations, together with comprehensive gut microbiome analyses, are needed to determine the translational relevance of these observations and to identify which mulberry-derived preparations offer the greatest potential for supporting gut and metabolic health.",
        "42511204": "ID: 42511204\nTitle: Postbiotics in Functional Foods: Preparation-Based Characterization, Gut-Brain Axis Interactions, and Translational Perspectives.\nAbstract: Postbiotics are defined as preparations of inanimate microorganisms and/or their components that confer a health benefit on the host. Although interest in postbiotics has increased substantially, their translational use in functional foods remains insufficiently characterized with respect to preparation identity, production methodology, food-matrix compatibility, mechanistic specificity, and regulatory positioning. This PRISMA-guided structured review aims to synthesize current evidence on postbiotics in functional food and nutraceutical contexts, with particular emphasis on preparation-based characterization, gut-brain axis-related mechanisms and clinical findings, food matrix applicability, and regulatory and health-claim considerations. Unlike broader postbiotic reviews that mainly address definitions, general health effects, or technological stability, this review integrates preparation identity, production process, gut-brain axis-related evidence, food matrix compatibility, and regulatory/health-claim translation within a single functional food framework. A structured literature search was conducted in Scopus and Web of Science Core Collection and was completed on 16 February 2026. The search strategy included three conceptual blocks: postbiotic and inactivation-based preparation terms, functional food/nutraceutical and food matrix terms, and gut-brain axis-related clinical and mechanistic terms. Cosmetic, topical, veterinary, animal feed, and aquaculture-focused publications were excluded. The export files contained 131 records from Scopus and 136 from the Web of Science Core Collection, yielding 267 records after applying document-type and language filters. After manually removing duplicates, 237 unique records were screened. Following title/abstract screening, 176 records were excluded as outside the scope of the review, and 61 publications were retained for full-text assessment and final thematic synthesis. The review was reported according to applicable PRISMA 2020 items. The evidence was organized into three thematic domains: gut-brain axis-related clinical findings, mechanistic evidence, and food matrix/product development applications. Heat-inactivated preparations, including Lactobacillus gasseri CP2305 and Lactiplantibacillus plantarum SNK12, have shown preliminary effects on stress-related symptoms, sleep quality, and selected neuroendocrine or inflammatory biomarkers in human studies. Mechanistic pathways include gut barrier integrity, immunomodulation, short-chain fatty acid signaling, tryptophan-kynurenine-serotonin metabolism, vagal communication, and regulation of the hypothalamic-pituitary-adrenal axis. Food matrix studies support the potential application of postbiotics in fermented dairy products, cereal-based systems, plant-based matrices, powders, concentrates, and bioactive packaging; however, matrix-dependent effects on bioavailability, sensory quality, and biological activity remain incompletely defined. Postbiotics provide a stable translational platform for functional-food development, but their scientific and commercial use requires clear characterization of the microbial source, production process, inactivation method, retained active fractions, dose metric, delivery matrix, and clinically meaningful endpoint. Future studies should avoid broad category-level claims and prioritize preparation- and matrix-defined human evidence with standardized safety reporting.",
        "42511301": "ID: 42511301\nTitle: Enhancing Nutritional and Health Benefits of Wheat Bran Through Bifunctional LAB Screening and BCAA-Enriched Fermentation.\nAbstract: Lactic acid bacteria (LAB)-mediated fermentation has been widely explored as a strategy to enhance the nutritional functionality of cereal processing by-products. In this study, 50 LAB strains previously isolated from Korean traditional fermented foods and obtained from the National Agrobiodiversity Center (KACC, Jeonju-si, Republic of Korea) were systematically screened for bifunctional carbohydrate and protein degradation capacities, and their potential to improve the nutritional functionality of wheat bran was evaluated. Paper disc assays revealed substantial inter-strain variability, with clear zone diameters ranging from 12.35 to 29.52 mm for carbohydrate degradation and 11.61 to 25.45 mm for protein degradation. Ten strains exceeding both upper-quartile enzymatic degradation cutoff thresholds (\u226525.25 mm for carbohydrate degradation and \u226517.98 mm for protein degradation, respectively) were putatively identified as Lactiplantibacillus plantarum and Lacticaseibacillus paracasei based on 16S rRNA gene sequencing (99.73-100% similarity). Substrate-specific fermentation using L. paracasei KS 595 across four substrates (brewed soy sauce soybean meal, pea, floury rice, and wheat bran) demonstrated substrate-dependent differences in growth and branched-chain amino acid (BCAA) accumulation, with the highest increase observed in pea fermentation. Strain-specific evaluation during wheat bran fermentation revealed distinct differences in growth kinetics, pH reduction, and BCAA production driven by cell-envelope proteinases and intracellular peptidases, with viable cell counts reaching 9-10 log CFU/mL after 48 h. Biogenic amine analysis indicated that histamine levels remained below commonly accepted safety limits in all strains, while L. paracasei KS 543 showed no detectable tyramine or histamine. Although the potential improvement in plant protein bioavailability was indirectly inferred through the free BCAA enrichment rather than directly measured in vivo, these results support a systematic screening approach for selecting LAB strains capable of producing BCAA-enriched fermented wheat bran, with potential implications for improving plant protein bioavailability and addressing nutritional needs in aging and active populations.",

In the context of chronic kidney disease (CKD) and renal transplantation, mounting evidence reveals a complex bidirectional relationship between the intestinal microbiota and kidney function-commonly referred to as the gut-kidney axis. Patients with CKD harbor a profoundly altered gut microbial ecosystem characterized by reduced diversity, depletion of beneficial commensal organisms, and expansion of pathobiont taxa capable of generating uremic toxins and pro-inflammatory mediators. These perturbations are further compounded by the uremic milieu itself, dietary restrictions, frequent antibiotic exposure, and the use of immunosuppressive agents following transplantation. The gut-liver-kidney axis adds an additional layer of complexity, linking hepatic metabolism, bile acid signaling, endotoxemia, and systemic immune activation to the progression of renal disease. Gut-derived metabolites-including short-chain fatty acids (SCFAs), bile acids, trimethylamine N-oxide (TMAO), and tryptophan-derived uremic solutes such as indoxyl sulfate and p-cresyl sulfate-serve as molecular mediators of inter-organ crosstalk and have been identified as both biomarkers and therapeutic targets. A growing body of literature supports the diagnostic and prognostic utility of microbiome composition and its metabolic signatures in patients with CKD and those undergoing renal replacement therapy. Therapeutic strategies aimed at restoring microbial homeostasis-encompassing dietary interventions, prebiotics, probiotics, synbiotics, fecal microbiota transplantation (FMT), bile acid-based therapies, and novel pharmacological approaches-hold considerable promise for improving outcomes in CKD and transplant recipients. Importantly, the bidirectional relationship between immunosuppressive drugs and the gut microbiota has emerged as a clinically significant determinant of both microbial ecology and drug pharmacokinetics: each major immunosuppressive agent class-corticosteroids, calcineurin inhibitors, mycophenolate mofetil, and mTOR inhibitors-induces characteristic dysbiotic patterns, while in turn, the microbiota modulates drug bioavailability through enzymatic biotransformation (notably bacterial beta-glucuronidase activity affecting mycophenolic acid enterohepatic recirculation) and modulation of host drug-metabolizing enzymes. This narrative review provides a comprehensive overview of the current understanding of microbiome dysbiosis in the setting of renal disease and transplantation, examines the mechanistic underpinnings of the gut-liver-kidney axis, details the multifaceted impact of dysbiosis on transplant outcomes-including allograft function and rejection, infection, post-transplant diabetes, and cardiovascular complications-and critically appraises the translational potential of microbiome-targeted interventions. We conclude by highlighting ongoing challenges and future directions toward personalized, microbiome-informed clinical care.",

Historically considered sterile, the lung harbors a dynamic, low-biomass microbiome that evolves continuously in response to pulmonary pathologies. Accumulating evidence underscores that respiratory health and structural recovery are not autonomous but are critically integrated with distal microbial systems, especially the intestinal tract, through the gut-lung axis (GLA). This review characterizes the GLA as a bidirectional communication highway fueled by immune pathways, microbial metabolites, and direct microbial translocations. During acute or chronic injuries, such as COVID-19, COPD, asthma, idiopathic pulmonary fibrosis (IPF) and lung cancer, the gut microbiota serves as a remote metabolic \"rheostat\". It delivers pivotal signaling molecules, such as short-chain fatty acids (SCFAs) and tryptophan metabolites (indoles), that could shape the local microenvironment in which the respiratory epithelium undergoes functional repair or maladaptive, fibrotic remodeling. Mechanistically, gut-derived butyrate enhances mitochondrial activity in alveolar epithelial cells, while resident progenitors, such as Alveolar Type 2 (AT2) cells, depend on intact mitochondrial fatty acid oxidation for proper regenerative differentiation. Conversely, critical lung illness disrupts this homeostasis via a \"pathological circuit,\" where severe pulmonary inflammation drives gut permeability, fecal dysbiosis, and the subsequent translocation of pathogen-associated molecular patterns (PAMPs, such as LPS) or gut-associated bacteria back into the pulmonary circulation. This review highlights the systemic nature of lung regeneration, which likely depends heavily on intestinal health through the GLA. Ultimately, leveraging these remote microbial networks through precision postbiotic supplementation, dietary priming, or microbiota transplantation represents a crucial frontier in precision medicine to promote definitive alveolar repair.",

The diet-gut microbiota-immune system-cancer axis is considered a key regulator of these processes. Among the bioactive compounds found in the diet, ellagitannins have garnered significant scientific interest due to their conversion by the gut microbiota into biologically active metabolites known as urolithins. Urolithin A (UroA), one of the best characterized compounds, exhibits broad anti-inflammatory, antioxidant, immunomodulatory, and anticancer properties. It modulates signaling pathways associated with inflammation, oxidative stress, mitochondrial dysfunction, and cell proliferation. Furthermore, UroA has been shown to improve intestinal barrier integrity, regulate immune cell activity, and induce mitophagy, thereby contributing to the restoration of mitochondrial and cellular homeostasis. A growing body of evidence also suggests that UroA may inhibit cancer cell proliferation, induce apoptosis, and disrupt the molecular pathways involved in colorectal carcinogenesis. This review summarizes the current state of knowledge regarding the biosynthesis and bioavailability of UroA, its molecular mechanisms of action in IBD, and its potential role in the prevention and treatment of CRC. Furthermore, the limitations of UroA-based therapies and future research directions are discussed. Although further, well-designed clinical trials are necessary, current findings suggest that UroA may represent a promising microflora-targeted therapeutic strategy in chronic inflammatory and CRC diseases.",

This study used a combination of 16s rRNA, transcriptome sequencing and liquid chromatography-mass spectrometry to investigate intestinal microbiota, genes and metabolic profiles in the ileum of Hu sheep fed broccoli extract. Here, we randomly allocated 14 Hu sheep to two diets: a basal diet without any supplementation (NC) and a basal diet supplemented with 200 mg/kg broccoli tail (BT). After 60 days of treatment, blood and jejunal samples were collected for serum biochemical indicators and multi-omics analysis. In this study, the extract of broccoli tails had a significant effect on the serum biochemical indicators, including white blood cells, red blood cells, mean corpuscular volume, mean corpuscular hemoglobin concentration, mean platelet volume, triglycerides and total protein in Hu sheep (p < 0.05). Transcriptomic analysis showed that the 672 differentially expressed genes between the NC and BT groups were primarily enriched in linoleic acid metabolism, steroid hormone biosynthesis, and cholesterol metabolism. Metabolomics analysis using Kyoto Encyclopedia of Genes and Genomes enrichment showed that the 41 differentially abundant metabolites were mainly enriched in bile secretion, vitamin B6 metabolism, and the mTOR signaling pathway. 16S rRNA sequencing results indicated that the extract of broccoli tails increased the relative abundance of Peptostreptococcaceae and decreased the relative abundance of Lachnospiraceae, Lachnospirales, and Bacteroidaceae. Integrated transcriptome, metabolome, and microbiome analysis showed that the gut microbiota and host transcriptomic changes may participate in systemic metabolic regulation by modulating amino acid metabolism, lipid signal transduction, nucleotide metabolism, and vitamin B6-related metabolic pathways. These findings demonstrate that the extract of broccoli tails modulates intestinal gene expression, systemic metabolism, and gut microbial ecology in Hu sheep, providing new insights into the utilization of agricultural byproducts as a functional feed supplement for ruminants.",

Although these agents have emerged as frontline standard therapies for malignancies, their clinical utility remains limited. Interpatient therapeutic variability is inextricably linked to the composition and functional capacity of the gut microbiome. The underlying mechanisms appear to involve a complex dialogue between the microbiota and host immune system, where microbial metabolites serve as critical mediators in remodeling the tumor microenvironment. Despite these insights, progression in the field remains constrained due to heterogeneity in study cohorts and sample-processing methodologies, hindering the establishment of reproducible individualized predictive models and clinical intervention strategies. Consequently, there is an urgent need to systematically delineate the microbiome-metabolite-immune axis to optimize the balance between ICI efficacy and systemic toxicity. By synthesizing the latest evidence, this review aimed to highlight the pivotal roles of specific taxa, including Bacteroides, Bifidobacterium, and Akkermansia muciniphila, in ICI efficacy. These microbes and their metabolic byproducts potentiate therapeutic responses by enhancing dendritic cell cross-presentation and promoting CD8+ T-cell infiltration, often via activation of the cyclic GMP-AMP synthase-stimulator of interferon genes or nucleotide-binding oligomerization domain-containing protein 2 signaling pathways. Furthermore, these microbial components demonstrate the ability to protect the heart and colon against inflammation and barrier disruption, thereby mitigating immune-related adverse events. Although the feasibility and safety of interventions such as fecal microbiota transplantation and supplementation with next-generation encapsulated probiotics, postbiotics, or dietary fiber have been demonstrated in preclinical and Phase I trials, substantial hurdles remain. Future progress requires large-scale, multicenter, standardized, longitudinal studies integrating metagenomics and metabolomics to construct robust cross-cancer and cross-population predictive models. Such rigorous validation would enable the development of precise microbial interventions that maximize therapeutic gains while minimizing the incidence of adverse reactions.",

This study evaluated the effects of replacing fish meal with yellow mealworm meal on growth performance, nutritional composition, intestinal microbiota, hepatopancreas metabolites, and immune defense against decapod iridescent virus 1 (DIV1) in giant freshwater prawn. Five isonitrogenous and isolipidic diets were formulated with yellow mealworm meal replacing fish meal at 0% (FM30), 10% (FM27), 20% (FM24), 40% (FM18), and 60% (FM12). A total of 750 prawns were randomly distributed into 15 tanks (three replicates per diet, 50 prawns per replicate) and cultured for 56 days, followed by a DIV1 challenge test. Results showed that Replacement of up to 60% of fish meal did not adversely affect growth performance, feed utilization, or the crude protein, crude lipid, and amino acid profiles in muscle. Muscle monounsaturated fatty acids (MUFAs) increased linearly with mealworm inclusion (p < 0.05). The FM12 group exhibited elevated arachidonic acid (ARA) and n-6 PUFA levels and reduced docosahexaenoic acid (DHA; p < 0.05), while the n-3/n-6 ratio remained unchanged. Gut microbiota composition shifted favorably, with increased abundance of Firmicutes and beneficial Lactococcus in the FM12 and FM18 groups (p < 0.05). Metabolic adaptation in the hepatopancreas involved glycerophospholipid metabolism, nucleotide metabolism, and pyruvate metabolism pathways. Following DIV1 challenge, the FM12 group showed significantly higher survival, increased plasma glutathione peroxidase (GPX) activity, decreased malondialdehyde (MDA) levels, and reduced hepatopancreatic apoptosis (p < 0.05). Immune-related upregulation of hpo, warts, mats, and ifn-\u03b1, alongside downregulation of caspase-3, was also observed (p < 0.05). In conclusion, replacing 60% of dietary fish meal with yellow mealworm meal is a nutritionally safe and beneficial strategy for giant freshwater prawn, effectively maintaining growth performance and muscle composition, modulating gut microbiota, and enhancing immune defense against DIV1.",

We previously revealed that dietary L-malic acid (L-MA) supplementation benefits maternal health in sows during late pregnancy. However, the effect of L-MA on sows during early pregnancy is largely unexplored. In the present study, in vitro assays confirmed that L-MA directly promoted the adhesion of embryonic trophoblast (JAR) cells to endometrial epithelial (Ishikawa) cells, and alleviated H\u2082O\u2082-induced reactive oxygen species (ROS) accumulation in the endometrial cells. In vivo, L-MA supply during early pregnancy optimized the physiological environment in sows, thereby improving pregnancy outcomes, without altering circulating estradiol or progesterone levels on GD 28. L-MA significantly enhanced maternal antioxidant capacity and alleviated inflammatory responses. Metabolomics analysis showed that L-MA reshaped the maternal metabolic profile, modulated amino acid, lipid and nucleotide metabolism, and activated the NOD-like receptor signaling pathway and the cGMP-PKG signaling pathway. L-MA enriched beneficial bacteria, including short-chain fatty acid (SCFA)-producing, anti-inflammatory, and antioxidant taxa, while repressing inflammation-associated bacteria, and these specific taxa were significantly correlated with differential metabolites, antioxidant/anti-inflammatory markers, and reproductive outcomes. Overall, our data revealed that dietary L-MA supplementation during early pregnancy enhanced reproductive performance in sows. These benefits might be associated with shifts in the maternal gut microbiota-metabolite axis and enhanced antioxidant and anti-inflammatory capacities. Therefore, L-MA supplementation may be a potential strategy for ameliorating embryo loss and improving reproductive performance in mammals.",

Recent work suggests that dysbiosis may not simply be a consequence of low iron status but may actively contribute to impaired absorption. This narrative review synthesizes the evidence on gut microbiota patterns in IDA across age groups, examines the mechanistic links between dysbiosis and iron metabolism, and identifies the potential roles of microbiota-related dietary and therapeutic strategies. This narrative review used a selective, theory-driven approach, based on targeted searches of PubMed, Scopus, and Web of Science (2005-2026), to synthesize heterogeneous human, experimental, and mechanistic evidence on gut microbiota-iron interactions in iron deficiency anemia (IDA). Evidence suggests a bidirectional, context-dependent relationship between IDA and gut microbiota involving host iron regulation, microbial competition, metabolites, and diet. Individuals with IDA often show reduced microbial diversity, depletion of SCFA-producing taxa, and enrichment of iron-scavenging bacteria, although direct causal evidence in humans remains limited. IDA is commonly associated with recurring dysbiosis patterns characterized by reduced short-chain fatty acid-producing commensals and relative enrichment of inflammatory, iron-competitive taxa. While iron supplementation remains the cornerstone of evidence-based IDA management, the ecological effects of unabsorbed luminal iron on gut microbial communities support the concept of a potential \"iron paradox,\" particularly in inflammatory or high-infection settings. Therefore, microbiota-targeted strategies should currently be regarded as hypothesis-generating concepts rather than established clinical interventions and require further mechanism and clinical validation.",
        "42523106": "ID: 42523106\nTitle: The associations of human genetic variations with airway microbiome, environmental exposures, and respiratory health.\nAbstract: The intricate interactions between environmental exposures, the respiratory microbiome, and host genetic variations remain inadequately understood in the context of respiratory health. This study utilized sputum metagenomic data from 1,651 individuals in our previous cohort to elucidate these associations. Mendelian randomization indicated that air pollutants (e.g., SO2, CO, and PM2.5) were associated with lung function, which is potentially mediated by microbes, such as Actinomyces, Haemophilus influenzae, and Veillonella spp. Several genetic loci associated with respiratory microbiome variation were found to be linked to genotype-dependent associations between environmental exposures and lung function. For bacteria, the MEOX1 locus (rs1973191819) was associated with lower Filifactor alocis abundance under air pollutant exposure. The FAM110D (1:26157175) and USP36 (rs1343834070) loci showed associations with higher levels of certain pathogenic taxa (e.g., Ralstonia pickettii, Neisseria) and lower levels of the commensal Oribacterium, increasing chronic obstructive pulmonary disease (COPD) risk. For fungi, DNAJC18 and CCDC57 loci exhibited associations with Candida and Penicillium abundance, respectively. These genotype-dependent associations between the microbiome and environmental exposures provide insights into airway dysbiosis and susceptibility to respiratory diseases. This study reveals why individuals exposed to identical air pollution exhibit varying degrees of respiratory severity, pointing to a critical missing link: our genetics. While pollution is a known disease trigger, our findings demonstrate that host genetic variation actively regulates and shapes the respiratory microbiome under environmental stress. By mapping specific genetic loci to pollutant-driven bacterial shifts, this work elucidates how host genetics filters environmental risks to govern microbial homeostasis. These results underscore the necessity of incorporating host-microbiome genetic regulation into environmental health research. Ultimately, this study shifts the paradigm toward personalized medicine, enabling the early identification of at-risk individuals and the development of targeted, microbiome-informed interventions.",

In this study, we preliminarily investigated the ameliorative effects and potential mechanisms of a polysaccharide, JP, derived from jujube (Ziziphus jujuba Mill.) on HUA. Our results showed that JP is an acidic polysaccharide with a molecular weight of approximately 1.5\u00a0\u00d7\u00a0105\u00a0Da, primarily composed of arabinose, glucose, and xylose. Daily administration of JP (50, 100, 200\u00a0mg/kg) dose-dependently reduced serum UA levels and attenuated renal injury in hyperuricemic model mice. Mechanistically, JP suppressed UA production by inhibiting renal xanthine oxidase activity, while concurrently promoting UA excretion via downregulating the expression of renal urate reabsorption transporters URAT1 and GLUT9. Furthermore, JP ameliorated renal injury through inhibiting the renal TLR4/NF-\u03baB signaling pathway, reducing TNF-\u03b1 levels, and alleviating oxidative stress and fibrosis. In addition, JP remodeled the disturbed gut microbiota, significantly enriching beneficial genera such as Akkermansia and Dubosiella. Collectively, JP exerts multifaceted ameliorative effects on HUA by modulating renal urate metabolism and inflammatory responses, as well as reshaping gut microbiota homeostasis. These findings provide preliminary experimental evidence for JP as a dietary intervention strategy targeting the gut-kidney axis to improve HUA and associated renal injury.",

Here, we define a new role for dietary taurine (Tau) protection against combined high-fat diet (HFD) and whole-abdominal irradiation (WAI) stress. In a two-sex murine model, we show that Tau intervention blocks metabolic organ damage and severe structural enteropathy. Histological analyses indicate that Tau preserves the intestinal mucosal barrier, which is accompanied by the restoration of Mucin 2 (MUC2) expression. Furthermore, 16S rRNA sequencing showed that Tau reshapes gut dysbiosis, increasing the relative abundance of the mucin-degrading bacterium Akkermansia muciniphila, which may potentially contribute to mucosal homeostasis. Coincident with the stabilization of this mucin-microbiome interface, we observed that Tau attenuates systemic endotoxemia and reduces inflammatory extracellular vesicle transmission of the gut-brain axis. Consequently, this reduced peripheral inflammation preserves hippocampal dentate gyrus (DG) architecture and ameliorates spatial memory deficit. Importantly, while this microbiome-gut-brain protection is similar in both sexes, systemic immune responses are strikingly sexually dimorphic, mandating a sex-stratified therapeutic approach. Together, these studies reveal a potential microbiome-associated link in Tau-induced systemic resilience, providing a translatable nutritional strategy against combined radiotoxic and metabolic disorders.",

We further explored whether the potential mechanistic role of queuine in enhancing lung epithelial cell viability under cigarette smoke exposure. Stable COPD patients were stratified into a high relative abundance of Proteobacteria group (CH) and a low relative abundance of Proteobacteria group (CL) using 16S rRNA gene sequencing of fecal samples. Airway microbiota profiles were analyzed in parallel to assess gut-lung axis coupling. Serum queuine concentrations were quantified using LC-MS/MS in healthy controls, COPD subgroups (CL and CH), and COPD patients complicated by lung cancer. Clinical symptoms (CAT, mMRC, SCSS) and spirometry (FEV1/FVC, FEV1, FEV1% predicted, FVC, FEF25-75%) were assessed. In vitro experiments were performed using cigarette smoke extract (CSE)-stimulated lung cancer epithelial A549 cells and bronchial epithelial BEAS-2B cells to determine the effects of queuine on cell viability. Chest CT imaging was analyzed to quantify pulmonary nodules as an indicator of in vivo epithelial proliferative activity. The \u03b1-diversity of gut microbiota did not differ between CH and CL. In contrast, \u03b2-diversity showed separation (PERMANOVA P\u00a0=\u00a00.062), with CH characterized by Proteobacteria enrichment and relative depletion of Firmicutes, Bacteroidota, and Actinobacteriota. Airway communities showed concordant remodeling with shifts in taxa consistent with dysbiosis. Serum queuine concentrations increased stepwise from healthy controls to COPD, were higher in CH than CL, and were highest in COPD complicated by lung cancer. Despite comparable pulmonary function and symptom scores between CH and CL groups, the CH group exhibited a significantly higher number of pulmonary nodules on CT imaging, particularly ground-glass nodules. In vitro, queuine significantly enhanced the viability of CSE-stimulated A549 lung cancer cells but failed to rescue CSE-induced growth inhibition in BEAS-2B cells. COPD-associated gut microbiota dysbiosis, particularly enrichment of Proteobacteria, is closely associated with elevated systemic queuine levels. Excess queuine enhances cell viability of smoke-exposed lung cancer epithelial cells and is associated with increased pulmonary nodules in vivo. These findings identify queuine as a microbiota-derived metabolic mediator that may connect COPD-related dysbiosis to abnormal proliferation of lung epithelial cells.",

So, this study looked at how a PFB at different doses influences the performance, digestibility, gut microbiota, blood biomarkers, liver health, and meat quality of growing rabbits. Sixty rabbits (body weight 552.63\u2009\u00b1\u200913.44\u2009g) were assigned at random to five dietary groups, having twelve replicates per group. The rabbits were fed a basal diet as a total mixed ration having 17.02% crude protein and 11.60\u2009MJ metabolizable energy/kg dry matter (DM), supplemented with PFB (g/kg diet) at 0.0 (control), 0.20, 0.40, 0.60, and 0.80. Following a 2\u2009weeks adjustment period, the feeding trial was conducted for 5\u2009weeks. When the trial was over, rabbits were sacrificed to collect digesta, blood, and meat samples for further analysis. Supplementation with PFB at 0.60\u2009g/kg diet (range: 0.50-0.70\u2009g/kg) showed a better final body weight (p\u2009=\u20090.01), weight gain (p\u2009<\u20090.001), and feed conversion ratio (p\u2009<\u20090.001), while significantly improving DM, nitrogen-free extract (p\u2009<\u20090.001), and ether extract (p\u2009=\u20090.02) digestibility. Besides, supplementation with PFB presented a linear reduction in Escherichia coli (p\u2009=\u20090.003), accompanied by linear improvement in Lactobacillus spp. (p\u2009<\u20090.001) and serum high density lipoprotein-cholesterol (HDL-C; p\u2009=\u20090.001). Broken-line analysis indicated optimal PFB supplementation levels of 0.60, 0.47, and 0.60\u2009g/kg diet for E.\u2009coli, Lactobacillus spp., and HDL-C, respectively. However, feed intake, serum triglycerides, other cholesterols, total protein, albumin, globulin, and uric acid remained unchanged across the groups. Furthermore, supplementation with PFB with an estimated breakpoint of 0.55\u2009g PFB/kg of diet effectively (p\u2009\u2264\u20090.02) reduced serum liver enzymes (aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase) indicating better liver health. In addition, PFB supplementation linearly reduced meat ether extract content and improved meat redness (p\u2009<\u20090.001), with optimal responses at 0.58 and 0.60\u2009g/kg diet, respectively, while having no impacts on meat protein, ash, lightness, or yellowness. Therefore, dietary inclusion of PFB at 0.55\u2009g-0.60\u2009g per kg diet optimized growth performance through enhanced weight gain, feed efficiency, and nutrient digestibility, while favorably modulating cecum microbiome, serum cholesterol, liver enzyme activities, and ameliorated meat quality.",

We constructed a mouse model using potassium oxonate (OXO) and a high-purine diet to examine the impacts of Jlus66 supplementation on hyperuricemia in vivo. The results revealed that Lacticaseibacillus paracasei Jlus66 intervention substantially lowered blood uric acid (UA) concentrations through suppressing xanthine oxidase (XOD) activity in the liver to reduce UA synthesis and modulating UA transport to enhance its renal excretion. Furthermore, Lacticaseibacillus paracasei Jlus66 supplementation increased short-chain fatty acids (SCFAs) in cecal samples, which might account for the reduced secretion of serum pro-inflammatory cytokines interleukin-6 (IL-6), interleukin-1\u03b2 (IL-1\u03b2), and tumor necrosis factor-\u03b1 (TNF-\u03b1). Lacticaseibacillus paracasei Jlus66 enhanced intestinal barrier function through upregulating tight junction proteins and reinstating gut microbiota homeostasis. In conclusion, Lacticaseibacillus paracasei Jlus66 may be a potential probiotic for the management of hyperuricemia through modulating gut microbiota, promoting UA excretion, and inhibiting UA synthesis.",

Studying the burden of rare variants in a genetically homogeneous founder population may help identify disease-associated alleles that are difficult to detect in more heterogeneous populations. Whole exome sequencing was performed on 123 patients with IPF and 1110 unrelated controls from Sardinia (Italy). Variant prioritisations were conducted according to the American College of Medical Genetics (ACMG) guidelines. In parallel, gene burden of rare predicted loss-of-function variants was assessed using the Cohort Allelic Sums Test (CAST) algorithm to identify genes significantly enriched in IPF cases compared with controls. Pathogenic or likely pathogenic variants in known telomere-related genes were identified in 11.4% of patients. These variants were associated with younger age at diagnosis and a higher prevalence among never-smokers. CAST analysis identified a significant enrichment of loss-of-function variants in 82 genes, including MUC5B (OR=443.1, false discovery rate=3.7E-05), functionally related to cilium organisation and motility, with a significant overrepresentation of dynein-related genes. This study supports the contribution of telomere-related variants to IPF susceptibility and suggests a possible role for rare variants affecting mucociliary pathways. Together, these findings broaden the current understanding of IPF biology in this cohort. The distinctive genetic background of the Sardinian population may have facilitated the identification of rare or population-specific variants, underscoring the potential value of founder populations in complex disease genetics.",
        "42541365": "ID: 42541365\nTitle: The gut microbiome and drug-resistant epilepsy: Microbiome-antiseizure medication interactions and implications for pharmacoresistance.\nAbstract: Drug-resistant epilepsy (DRE) affects approximately one-third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a potentially modifiable factor that may function as a systems-level modifier of these established mechanisms rather than a standalone pathway. The gut microbiome harbors a vast repertoire of drug-metabolizing enzymes capable of directly biotransforming orally administered antiseizure medications (ASMs)-including valproic acid, lamotrigine, carbamazepine, and oxcarbazepine-thereby altering their pharmacokinetics, bioavailability, and therapeutic efficacy. Additionally, microbial metabolites modulate host cytochrome P450 enzymes, nuclear receptors, and efflux transporters such as P-glycoprotein, while bacterial \u03b2-glucuronidases influence the enterohepatic recirculation of glucuronidated ASMs. Conversely, chronic ASM exposure reshapes the gut microbial ecosystem, creating a self-perpetuating cycle of dysbiosis and pharmacoresistance. This narrative review synthesizes current evidence on microbiome-ASM interactions in DRE, proposes a concrete experimental pipeline for characterizing ASM-specific microbial biotransformation, and outlines a framework for integrating physiologically based pharmacokinetic modeling with microbiome data. We discuss clinical implications for epileptologists-including the role of therapeutic drug monitoring in detecting microbiome-mediated pharmacokinetic variability, the concept of microbiome-neutral ASM selection, and earlier deployment of the ketogenic diet as a microbiome-targeted intervention. We highlight the translational potential of pharmacomicrobiomics-the study of how microbiome variation influences drug disposition and response-and identify critical knowledge gaps that warrant future investigation. PLAIN LANGUAGE SUMMARY: About one in three people with epilepsy continue to have seizures despite treatment. This review summarizes growing evidence that the gut microbiome-the community of bacteria living in the intestines-can influence how seizure medications work by altering their absorption, metabolism, and clearance. The medications themselves can reshape the microbiome in return, creating a cycle that may sustain treatment failure. Understanding this gut-drug relationship may open new paths to personalized epilepsy care through diet, probiotics, and microbiome-guided prescribing.",

This review synthesizes the environmental journey of MNPs by framing them as dynamic colloidal particles and mechanistically tracing their pathway from source to biological uptake. We discuss fundamental interfacial processes, including DLVO and non-DLVO interactions, straining, and air-water interface capture, governing MNP mobility and retention in porous media. These processes control MNP dispersal and potential to contaminate groundwater and agricultural systems. The interplay of colloidal properties (size, shape, surface chemistry) with environmental parameters is examined to explain exposure routes. We also detail how this colloidal behavior dictates bioavailability, facilitating MNP uptake in plants and soil fauna and amplifying their role as vectors for co-contaminants and antibiotic resistance genes. Human biomonitoring studies reveal MNPs in blood, stool, placenta, and bronchoalveolar lavage fluid. Systematic review evidence indicates associations with cardiovascular inflammation, endothelial dysfunction, and fibrosis; in vitro studies demonstrate PS MP-induced reductions in human sperm motility, vitality, and fertility-related gene expression; and cross-sectional studies link higher fecal MNP concentrations to gut microbiota dysbiosis, including increased abundance of harmful bacteria and decreased beneficial taxa. However, causation remains unestablished due to methodological heterogeneity and the predominance of cross-sectional designs. By integrating colloid science with ecotoxicology and exposure science, this review bridges the gap between MNP physical transport and adverse health outcomes, provides a framework for risk assessment, and highlights urgent research priorities, including standardized methods, longitudinal studies, and human-relevant models.",

One of the less explored areas is the role of the lung-brain axis, a sophisticated and intricate bidirectional connection between these two vital organs. Inhaled air pollutants can disrupt lung microbiome homeostasis. This disruption, analogous to gut dysbiosis implicated in neurological conditions, may contribute to epilepsy pathogenesis. Here, we review the existing evidence and theoretical foundations supporting the hypothesis that dysbiosis within the lung microbiota may play a role in the pathophysiology of epilepsy. This includes the links between environmental factors (particularly air pollution) and epilepsy susceptibility; the associations between lung-intrinsic microbiota dysregulation and neurological dysfunction; and the underlying molecular, immunological, and neural mechanisms that enable the lung-brain axis to modulate epileptogenesis. Furthermore, we outline the possible potential pathogenic mechanisms of epilepsy from the perspective of the microbiota-lung-brain axis, offer fresh perspectives on the pathophysiology of epilepsy, and explore potential new research directions related to the lung-brain axis and epilepsy. We propose that a deeper understanding of the function of the lung-brain axis will provide new insights into the etiology, diagnosis, prognosis, and treatment of epilepsy.",

Systemic inflammatory cascades serve as a cardinal etiological driver of AECOPD, emanating from multifaceted host-pathogen interactions involving viral, bacterial, or polymicrobial infections, superimposed upon environmental modulators that collectively precipitate accelerated pathological progression. These contributory elements markedly escalate the inflammatory milieu within the small airways, surmounting endogenous anti-inflammatory safeguards, thereby precipitating airway epithelial barrier disruption, microvascular dilation, edema, and prolific immune cell infiltration, which in turn perpetuate an inflammatory amplification loop. Such mechanisms converge to synergistically impair pulmonary function and extend durations of inpatient care. Current therapeutic paradigms for AECOPD predominantly incorporate bronchodilators, anti-inflammatory pharmacotherapies, supplemental oxygen administration, and mechanical ventilatory support. Notwithstanding these interventions, persistent limitations include the adverse sequelae of protracted systemic glucocorticoid therapy, escalating antimicrobial resistance profiles, and ventilator-associated morbidities. Ergo, there exists an imperative to investigate novel therapeutic modalities that confer enhanced safety and efficacy. TCM proffers salient therapeutic merits via its multi-target and multi-pathway pharmacodynamics, facilitating regulation of pivotal signaling pathways, including the Toll-like receptor 4(TLR4)/nuclear factor-\u03baB(NF-\u03baB), NF-\u03baB/NOD-like receptor pyrin domain containing 3(NLRP3), phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt), Janus kinase(JAK)/signal transducer and activator of transcription(STAT), and neutrophil elastase(NE)/mucin 5AC(MUC5AC) pathways. Through such regulatory interventions, TCM efficaciously attenuates inflammatory response, ameliorates symptomatic burden, and diminishes the incidence of AECOPD. The present investigation endeavors to delineate systematically the extant advancements in TCM-mediated regulation of inflammation-related signaling pathways within the context of AECOPD, thereby furnishing a robust theoretical framework and empirical guidance for optimized clinical interventions and pharmaceutical innovations in AECOPD management.",
        "42543328": "ID: 42543328\nTitle: [Role of \"gut lung axis-NETs\" pathway in chronic obstructive pulmonary disease based on theory of \"deficiency, phlegm, stasis, and toxin\"].\nAbstract: Chronic obstructive pulmonary disease(COPD) is a systemic disease characterized by persistent airflow limitation and airway inflammation, with a consistently high incidence and a lack of effective clinical interventions to reverse disease progression. Based on the core TCM pathogenesis theory of "deficiency, phlegm, stasis, and toxin", this paper systematically explores the critical role of the "gut lung axis-neutrophil extracellular traps(NETs)" pathway in the occurrence and development of COPD, as well as its intrinsic association with TCM pathogenesis. Specifically, dysbiosis of the intestinal microecology and dysregulation of pulmonary NETs persist throughout the disease course. Among these, "deficiency of healthy Qi" serves as the initiating factor; disruption of the gut microbiota and deficiency of metabolic products lead to decreased pulmonary defensive function and immunometabolic imbalance. Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream. As an "endogenous toxin", LPS activates pulmonary neutrophils, triggers oxidative stress, and promotes the formation of NETs. Moreover, the explosive release of pulmonary NETs represents the microscopic entity of the pathological products of "phlegm, stasis, and toxin". The highly viscous DNA backbone of NETs contributes to the formation of "tenacious phlegm" that obstructs the airways; NETs-induced immunothrombosis leads to "stasis obstructing lung collaterals"; and the cytotoxic proteins carried by NETs act as "virulent toxins" that directly damage the lung parenchyma. These pathological processes are the microscopic manifestations of the core pathogenesis of COPD, namely "deficiency leading to excess", "intertwining of phlegm and stasis", and "toxin damaging lung collaterals". In this context, spleen Qi deficiency drives dysregulation of the gut-lung microecology; the influx of endogenous toxins induces NETs activation; and the accumulation of phlegm, stasis, and toxin aggravates lung tissue remodeling. Accordingly, this paper proposes the application of the "consolidating the foundation and clearing the source" method to reconstruct intestinal microecology and block the origin of endogenous toxins, as well as the "removing toxins and dredging collaterals" method to target NETs regulation for resolving phlegm and removing stasis. Through dual "gut-lung" targeting to restore systemic homeostasis, this study provides a theoretical basis and new insights for the integrated TCM and western medicine prevention and treatment of COPD.",

Given IM's heterogeneous symptoms and evidence linking microbiota to viral infection, this may inform novel prevention or treatment strategies. Methods We employed a bidirectional two-sample MR framework using summary data from 207 gut microbial taxa and 205 metabolic pathways (Dutch Microbiome Project, n = 7,738) and the FinnGen consortium. Causality was assessed via inverse variance weighting (IVW), MR-Egger, weighted median, and mode-based estimation. Statistical significance was set at P <0.05 (Bonferroni-corrected), with instruments validated by F-statistics >10. Heterogeneity and pleiotropy were evaluated using Cochran's Q, MR-Egger intercepts, and leave-one-out analyses. Results Forward MR: Several bacterial pathways and taxa were\u00a0positively associated with IM risk. These include the de novo purine nucleotide biosynthesis II superpathway (odds ratio (OR) = 1.246, 95% confidence interval (CI): 1.026-1.514, P = 0.027), anhydromuropeptide recycling (OR = 1.24, 95% CI: 1.014-1.517, P = 0.036), the superpathway of unsaturated fatty acid biosynthesis (Escherichia\u00a0coli) (OR = 1.194, 95% CI: 1.019-1.4, P = 0.028), Lactobacillaceae\u00a0(OR = 1.109, 95% CI: 1.02-1.206, P = 0.016), and Lactobacillus\u00a0(OR = 1.108, 95% CI: 1.017-1.207, P = 0.019). Conversely, several taxa and pathways exhibited protective effects. These include the glucose-1-phosphate degradation pathway (G1P-DP) (OR = 0.852, 95% CI: 0.731-0.994, P = 0.042), heme biosynthesis from glutamate (OR = 0.809, 95% CI: 0.676-0.969, P = 0.032), the superpathway of L-tyrosine biosynthesis (OR = 0.9, 95% CI: 0.811-0.998, P = 0.046), the flavin biosynthesis I pathway (OR = 0.817, 95% CI: 0.672-0.993, P = 0.042),\u00a0Streptococcaceae\u00a0(OR = 0.869, 95% CI: 0.779-0.968, P = 0.011), and\u00a0Streptococcus\u00a0(OR = 0.844, 95% CI: 0.731-0.937, P = 0.020). Reverse MR: IM was found to causally alter gut microbiome composition. IM was associated with a decrease\u00a0of beneficial genera such as Roseburia\u00a0(OR = 0.901, 95% CI: 0.837-0.982, P = 0.016) and Bacteroides ovatus\u00a0(OR = 0.915, 95% CI: 0.841-0.995, P = 0.038), as well as Streptococcus\u00a0(OR = 0.876, 95% CI: 0.775-0.991, P = 0.035). Conversely, IM increased the risk of enrichment for Prevotellaceae\u00a0(OR = 1.107, 95% CI: 1.016-1.210, P = 0.020) and Prevotella copri\u00a0(OR = 1.096, 95% CI: 1.000-1.200, P = 0.048). Regarding metabolic pathways, IM increased the risk of polyamine biosynthesis II (OR = 1.123, 95% CI: 1.016-1.243, P = 0.024), L-lysine biosynthesis II (OR = 1.094, 95% CI: 1.008-1.118, P = 0.031), and L-lysine biosynthesis VI (OR = 1.083, 95% CI: 1.000-1.172, P = 0.048), while showing a protective association with L-rhamnose degradation I (OR = 0.922, 95% CI: 0.851-0.999, P = 0.046). Conclusion This study provides genetic evidence of a bidirectional causal relationship between the gut microbiome and IM. These findings suggest that IM may influence gut microbial ecosystem structure, characterized by a reduction in beneficial symbionts (e.g., Roseburia) and an enrichment of potentially pro-inflammatory taxa (e.g., P.\u00a0copri). These findings may inform future microbiota-targeted interventions or risk stratification strategies for EBV-related diseases.

Although its pathogenesis is multifactorial, growing evidence indicates that vitamin B complex deficiency contributes to muscle deterioration through interconnected metabolic and signaling pathways. This narrative review summarizes current evidence regarding the roles of B vitamins in skeletal muscle biology and their potential contribution to sarcopenia. Vitamin B deficiency impairs mitochondrial energy metabolism by reducing cofactor availability and adenosine triphosphate production, thereby increasing oxidative stress and chronic inflammation. These disturbances may trigger endoplasmic reticulum stress and the integrated stress response, leading to activating transcription factor 4 (ATF4)-dependent induction of growth differentiation factor 15 (GDF15) and fibroblast growth factor 21 (FGF21) expression. Collectively, these changes disrupt protein homeostasis, suppress anabolic signaling, impair neuromuscular function, and alter myokine secretion by reducing anabolic mediators while increasing catabolic and inflammatory myokines, thereby accelerating muscle loss and functional decline. Current evidence is the strongest for vitamins B6, B9, and B12, whereas mechanistic and clinical data for B2, B3, B5, and B7 remain limited. Overall, vitamin B deficiency can be viewed as a modifiable biological contributor to sarcopenia. Well-designed prospective studies and randomized clinical trials are required to clarify causality, validate biomarkers, and determine whether targeted vitamin B supplementation can enhance exercise- and nutrition-based strategies for preserving muscle health in older adults.",

The objective of this study was to evaluate three indigenous strains of lactic acid bacteria (LABs): Enterococcus faecium JK96, Pediococcus acidilactici JK148, and Lactobacillus pentosus JK151, isolated from the gastrointestinal tract of free-range, native Ivory Coast chickens, as probiotic candidates for commercial broiler production. To this end, in a 42-day completely randomized trial, 480 one-day-old Cobb 500 broiler chicks were divided into six treatment groups: three individual probiotic strains, a combination of several strains (1:1:1), an antibiotic growth promoter (Tylo-dox), and an untreated control group. Each group consisted of two pens of 40 chickens each. Freeze-dried probiotic powders (viable cell count: ~1.0\u2009\u00d7\u200910\u00b9\u2070 CFU/g) were administered daily in drinking water at a rate of 0.5\u00a0g per 10\u00a0L. Growth performance, blood biochemical parameters, and intestinal microbiota were assessed in 42-day-old chickens. The results of this study showed that probiotic supplementation significantly improved average daily gain (ADG) and feed conversion ratio (FCR) compared to the control and antibiotic-treated groups. The Lactobacillus pentosus JK151 strain achieved the highest ADG on day 28 (108.27\u00a0g/day vs. 83.83\u00a0g/day in the control group), maintained an FCR below 2.0 throughout the finishing period, and exhibited no cumulative mortality, compared to 5.0% in the antibiotic-treated group. No significant differences were observed in serum biochemical parameters (glucose, total protein, albumin, triglycerides, cholesterol, uric acid, alkaline phosphatase) or carcass characteristics between treatments (p\u2009>\u20090.05), thus confirming the physiological safety of all tested strains. All probiotic groups significantly reduced the intestinal bacterial load of Escherichia coli (1.38-9.54\u2009\u00d7\u200910\u2077 CFU/g) compared to the untreated control group (9.81\u2009\u00d7\u200910\u2079 CFU/g) and the antibiotic-treated group (1.10\u2009\u00d7\u200910\u2079 CFU/g), without significantly altering the total mesophilic aerobic flora or lactic acid bacteria populations. Notably, the antibiotic-treated group exhibited a higher bacterial load of E. coli than the control group, These results demonstrate that indigenous strains of lactic acid bacteria, in particular L. pentosus JK151, are effective, safe and locally adapted alternatives to growth-promoting antibiotics (GPAs) for sustainable broiler chicken production in C\u00f4te d'Ivoire.",

By producing ammonia to neutralize gastric acid, the key virulence factor urease is essential for H. pylori acid tolerance, thereby representing a promising therapeutic target. In this study, we identified luteolin as a potent urease inhibitor (IC50\u2009=\u200930.50\u2009\u03bcg/mL) from a screening of over 200 natural compounds. Further investigation through molecular docking, dynamics simulations, cellular thermal shift assay, and enzyme kinetics studies confirmed its competitive binding to the Ni2+-centered catalytic site of H. pylori urease (HPU). Luteolin exhibited potent anti-H. pylori activity under standard and simulated gastric conditions, and showed low propensity for resistance development over 14 serial passages. Proteomic and metabolomic analyses revealed that luteolin inhibited HPU activity, and the consequent ammonia restriction triggered severe metabolic dysfunction, characterized by disruptions in nucleotide, amino acid biosynthesis and TCA cycle. In GES-1 cells, luteolin protected against H. pylori-induced damage. In a mouse model of H. pylori-induced peptic ulcer, luteolin treatment significantly reduced the bacterial load, with concomitant alleviation of gastric mucosal pathology and suppression of inflammatory responses. In contrast to antibiotic-induced gastric microbial dysbiosis, microbial diversity analysis indicated that luteolin treatment had minimal impact on the resident gastric microbiota. In summary, as a urease inhibitor, luteolin suppresses H. pylori by blocking ammonia production, thereby disrupting acid neutralization and inducing metabolic dysfunction, which collectively alleviates gastric damage and inflammation while minimizing microbiota disruption and resistance risk.",

Sputum and clinical data were collected at baseline (T0), exacerbation (T1), and recovery (T2). Microbiota structure was analyzed via 16S rRNA sequencing, and levels of immune markers such as interleukin-8 (IL-8) and IL-1\u03b2 were measured by Enzyme-Linked Immunosorbent Assay (ELISA). Statistical analysis was performed by integrating clinical scale scores and nursing adherence data. At T1, airway microbial \u03b1 diversity was remarkably lower than at T0 and T2 (p < 0.01). The relative abundances of Haemophilus and Prevotella increased, while those of Veillonella and Lactococcus decreased (p < 0.01). Levels of IL 8, IL 1\u03b2, and TNF \u03b1 were elevated, and Secretory Leukocyte Protease Inhibitor (SLPI) levels were reduced at T1 (p < 0.01). Notable correlations were found between microbiota and immune markers (e.g., Haemophilus abundance with IL 8 levels, r = 0.52, p < 0.01), and these were positively associated with clinical scores such as COPD Assessment Test (CAT) and St. George's Respiratory Questionnaire (SGRQ) (p < 0.05). Patients with >80% inhaler adherence and regular breathing exercises/nutrition had higher microbial diversity and attenuated inflammation (p<0.05). The airway microbiota-immune axis in COPD patients demonstrates a disease stage-dependent imbalance, characterized by microbial dysbiosis and enhanced pro-inflammatory responses during acute exacerbation. Good nursing adherence can modulate this axis's homeostasis, offering novel targets for precision nursing.",

Integrated 16S rRNA gene sequencing and untargeted LC-MS/MS metabolomics revealed that CB-a (1 \u00d7 10\u2078 CFU/mL, administered orally) fundamentally restructured the colonic microbial architecture. Specifically, it enriched beneficial, short-chain fatty acid (SCFA)-producing consortia (e.g., Lactobacillus, Bacteroides, and Alloprevotella) while suppressing opportunistic pathobionts (Escherichia-Shigella) and mitigating excessive mucin-degrading bacteria (Akkermansia). This ecological shift was accompanied by a pronounced metabolic reconfiguration, highlighted by the significant restoration of fecal SCFA pools, predominantly butyrate (P < 0.05). Mechanistically, multi-omics correlation potential that the CB-a-driven microbial remodeling alleviates mucosal inflammation through SCFA-linked host-microbe signaling. This pathway explicitly involves the upregulation of G-protein-coupled receptors (GPR41, GPR43, and GPR109A), the inhibition of histone deacetylases (HDAC1/2), and the subsequent reinforcement of epithelial tight junction proteins (ZO-1, Occludin). Furthermore, CB-a significantly attenuated systemic pro-inflammatory cytokine expression while restoring superoxide dismutase (SOD) antioxidant capacity. These findings provide mechanistic insights into how this specific environmental isolate modulates the intestinal microenvironment, offering a robust theoretical basis for deploying C. butyricum in functional interventions targeting microbiota-associated inflammatory disruptions.IMPORTANCESevere gut inflammation, such as inflammatory bowel disease, is often driven by a breakdown in our natural gut bacteria. Although probiotics are popular treatments, how they actually repair the gut remains largely unknown. Our study highlights the remarkable healing ability of Clostridium butyricum CB-a, a natural bacterium isolated from the environment. We discovered that this microbe acts as an ecological engineer for the digestive system. It actively rescues the damaged gut by promoting the growth of beneficial bacteria and suppressing harmful ones. This positive shift triggers the release of natural, healing molecules that calm the immune system and rebuild the protective gut lining. By uncovering the exact steps this bacterium takes to restore digestive harmony, our work provides a powerful blueprint for designing highly targeted, natural probiotic therapies to combat severe intestinal diseases.",

Due to its high expression in the liver and gastrointestinal tract, XOR has emerged as an important regulator of redox homeostasis, innate immunity and metabolic adaptation in digestive diseases. This review examines the role of XOR in hepatic disorders, intestinal ischemia-reperfusion (I/R) injury and inflammatory bowel disease (IBD), focusing on oxidative stress, tissue injury, host-microbiome interactions and carcinogenesis. Evidence indicates increased XOR activity in inflammatory and fibrotic liver diseases, where ROS generation contributes to hepatocellular damage, fibrosis and disease progression. In intestinal I/R injury, XOR links ATP depletion and hypoxanthine accumulation to reperfusion-associated oxidative stress, barrier dysfunction, bacterial translocation and systemic inflammation. In IBD, XOR participates in cytokine amplification, redox imbalance, thiopurine metabolism and inflammation-associated colorectal carcinogenesis. Emerging evidence also supports bidirectional interactions between XOR/urate metabolism and the gut microbiota, suggesting a broader role for XOR in regulating intestinal immune homeostasis. However, the biological significance of XOR is strongly context dependent. Whereas increased XOR activity promotes inflammatory tissue injury, advanced gastrointestinal malignancies are frequently characterized by reduced XOR expression, loss of cellular differentiation and enhanced de novo purine synthesis. Overall, XOR emerges as a central, but highly plastic, regulator at the interface between metabolism, inflammation and host-microbiome interactions in digestive diseases. Its clinical exploitation will depend on the ability to understand, rather than oversimplifying, this complexity.",

Despite high initial response rates, long-term relapse in OC remains frequent, while conventional markers capture only short-term therapeutic sensitivity. Whether longitudinal gut-microbiome trajectories during chemotherapy are associated with long-term recurrence remains unknown. Within the prospective SOCFCP cohort (N\u2009=\u200991; 13 recurrences), 100 serial fecal samples from a 33-patient sub-cohort were analyzed by 16S rRNA sequencing across the early, middle and late chemotherapy phases. Microbial successional trajectories and their association with recurrence were assessed by linear mixed-effects modeling, multivariable MaAsLin3 and repeated-measures correlation (rmcorr) networks, alongside stratified and covariate-adjusted sensitivity analyses and patient-level bootstrap assessment. The cumulative severe-toxicity-recurrence relationship was estimated by Firth penalized-likelihood regression, suited to sparse, separation-prone events. Microbial \u03b1-diversity rose progressively across the chemotherapy course (Shannon time effect p\u2009=\u20090.002), consistent with ecological succession, with higher turnover among peripheral than in core taxa (p\u2009=\u20090.005). Cumulative severe toxicity was not associated with recurrence (Firth OR\u2009=\u20090.99, 95% CI 0.68-1.39). Crucially, recurrent patients exhibited a progressive depletion of Fusicatenibacter (recurrence\u2009\u00d7\u2009time coefficient\u2009=\u2009-5.35, q\u2009<\u20090.001) that persisted across all sensitivity analyses-stratified, medication-adjusted, antibiotic-depleted and clinically-adjusted models (coefficient -4.60 to -5.66, all q\u2009<\u20090.001). PICRUSt2-based functional inference identified recurrence-associated differences in predicted de novo nucleotide-biosynthesis and cell-wall-assembly pathway abundance (q\u2009<\u20090.05). A bootstrap-supported co-variation network further linked specific taxa, notably Escherichia-Shigella and Roseburia, to these recurrence-associated pathways. Chemotherapy-driven gut-microbiome remodeling, in particular the recurrence-associated depletion of Fusicatenibacter, was associated with long-term OC relapse, whereas cumulative severe toxicity showed no significant association with recurrence. These longitudinal microbial dynamics support a candidate non-invasive marker that warrants external validation, and provide a hypothesis-generating rationale for testing whether targeting specific predicted bacterial functional pathways can modulate the host anti-tumor milieu.",

Previous clinical studies showed that YHJF improves Sequential Organ Failure Assessment (SOFA) scores and modulates gut microbiota in elderly patients with pneumonia-associated sepsis. However, the mechanism by which YHJF protects against sepsis-associated acute lung injury (SALI) remains unclear. A murine SALI model was established by cecal ligation and puncture (CLP). Therapeutic effects were evaluated by histopathology, micro-CT, pulmonary function assessment, and ELISA. Mechanistic studies included proteomic analysis of lung tissues and LPS-stimulated MH-S macrophages, pharmacological modulation with Mdivi-1 and urolithin A (UA), macrophage-epithelial co-culture, HPLC fingerprinting, UPLC-HRMS, and molecular docking. YHJF significantly improved 7-day survival and ameliorated lung injury, pulmonary edema, respiratory dysfunction, and systemic inflammation in mice with CLP-induced SALI. Proteomic profiling and subsequent functional assays suggested that enhanced mitophagy in macrophages represents a central protective mechanism. In vivo, YHJF increased autophagosome formation and PINK1/Parkin co-localization in BALF-derived alveolar macrophages. In vitro, YHJF restored mitochondrial homeostasis by activating PINK1/Parkin-dependent mitophagy in macrophages. This was accompanied by reduced cytoplasmic mtDNA leakage, downregulated cGAS expression, and suppression of the STING-TBK1-IRF3 pathway and subsequent type I interferon responses. Pharmacological inhibition of mitophagy with Mdivi-1 abolished these protective effects of YHJF, whereas activation with UA augmented them, demonstrating that mitophagy is necessary for YHJF-mediated protection. In a macrophage-epithelial co-culture system, YHJF-treated macrophages alleviated LPS-induced apoptosis in MLE-12 alveolar epithelial cells. Furthermore, chemical analysis integrated with molecular docking identified aloe-emodin, rhein, and genistein as candidate bioactive constituents of YHJF that likely contribute to its regulation of macrophage mitophagy. YHJF protects against SALI by restoring macrophage mitophagy and suppressing mtDNA-STING-mediated inflammatory signalling. These findings support YHJF as a potential therapeutic strategy for sepsis-associated lung injury.",

One of the most powerful modulators of microbial composition and function is diet. Using the E\u00b5-TCL1 murine model of B-cell chronic lymphocytic leukemia (CLL), we assigned male and female mice to a high-fat, high-carbohydrate Western diet (HF) or standard chow (CH) diet. Mice consuming a HF diet had significantly shorter survival than those consuming a CH diet, irrespective of sex. We also observed a significant increase in splenic involvement by CLL in the HF diet-fed mice at time of sacrifice. Mice receiving the HF diet demonstrated immediate and profound effects on the gut microbiome, marked by reduced alpha diversity and significantly different community composition as measured by beta diversity. A larger change in alpha diversity between the pre-CLL engraftment (F1) and 4-weeks post-engraftment (F3) assessment significantly correlated with higher disease burden at week 4 (p\u00a0=\u00a00.009, r = 0.406) and worse survival (p\u00a0=\u00a00.001, r = -0.492). Notably, there was a sustained increase in Akkermansia muciniphila and Bacteroidetes thetaiotaomicron in HF diet-fed mice, coupled with a corresponding increase in microbiome functional pathways related to arginine and histidine biosynthesis, chitin degradation, and nucleotide biosynthesis. Collectively our data provides evidence of the profound and sustained impact of a high-fat Western diet on the gut microbiome community and CLL pathogenesis in the E\u00b5-TCL1 murine model of CLL.",

We applied broncho-alveolar lavage fluid (BALF) genomic sequencing to identify biomarkers for asthma and chronic obstructive pulmonary disease (COPD). Between December 2023 and February 2025, 1-146 adults with suspected LRTI enrolled from the First Hospital of Jilin University underwent BALF next-generation sequencing. Patients were stratified by lung function, with the impaired pulmonary function group further divided into asthma, COPD-mild-moderate, and COPD-severe subgroups. Disease-specific key biomarkers were identified using machine learning algorithms and analyzed for co-occurrence. Impaired pulmonary function was not only associated with pathogenic microorganisms and its higher microbial burden, but also associated with a distinct community structure. Random forest models revealed disease-specific biomarkers, with Prevotella intermedia, Finegoldia magna, and Human parvovirus enriched in asthma, Veillonella parvula, Human respiratory syncytial virus, and Haemophilus influenzae enriched in COPD-mild-moderate, and Human respiratory syncytial virus, Human coronavirus, and Human parainfluenza virus enriched in COPD-severe. Co-occurrence network identified hubs linking asthma-centric (Haemophilus parainfluenzae and Schaalia odontolytica) and COPD-centric (Klebsiella pneumoniae, Veillonella parvula, and Streptococcus constellatus) clusters, suggesting potential cross-phenotype microbial crosstalk. Genomic sequencing profiling delineates distinct yet overlapping airway microbiota across separate pulmonary dysfunctional diseases - asthma and COPD.

This review systematically investigates the \"gut microbiota-uric acid metabolism axis\" as a potential target for inhibiting Hyperuricemia (HUA). This review introduces the four functions of the axis: direct reduction of uric acid, intestinal excretion, regulation of uricase expression, and the intestinal-renal axis signal; then investigates how hypoxia alters all of these paths. In addition, this review illustrates how this axis is related to the classical metabolic pathway of purine synthesis, renal excretion, lactate metabolism, inflammatory-oxidative stress and genetic susceptibility. Adaptation difference: Native highlanders and migrants show different degrees of adjustment to life in the mountains, and migrants are relatively more prone to axis dysfunction. Finally, this review introduces targeted intervention strategies, such as probiotics, prebiotics, fecal microbiota transplantation, and their combination with uric acid-lowering or anti-inflammatory drugs, and put forward a population-stratified precision intervention framework.

In this study, we investigated whether high methoxyl pectin (HMP), a soluble dietary fiber found in fruits/vegetables and an additive for the food industry would impact \u03b2-carotene bioaccessibility under various physiological digestive conditions, following the INFOGEST gastrointestinal model. Concentrations of pancreatin plus bile salts and shear forces (simulated by varying water bath rounds/min. and glass bead addition) were modified in the presence (1.15\u00a0mg/mL digesta) and absence of HMP. Endpoints measured in the digesta included \u03b2-carotene bioaccessibility, surface tension, viscosity, micelle size, zeta potential, and triglyceride lipolysis. Adding HMP reduced overall bioaccessibility of \u03b2-carotene from 32.1\u00b16.2% to 24.1\u00b15.7% (p<0.001). All other parameters also had a significant impact on the bioaccessibility of \u03b2-carotene, that is, bile/pancreatin concentration (p<0.001), water bath shaking speed (p<0.001), and glass beads (p\u00a0=\u00a00.001). Surface tension, viscosity, and micelle size were less strongly affected by HMP addition (p<0.05), though not triglyceride lipolysis. The inhibitory effect of HMP varied depending on bile/pancreatin concentration and shear-forces, with strongest reductions when \u03b2-carotene bioaccessibility was highest at onset.",

Due to its complex characteristics and progressive development, efficient diagnosis and management are essential for enhancing dairy productivity. This pilot study employed 16S rRNA amplicon sequencing using Oxford Nanopore's MinION to investigate the milk microbiota of healthy and mastitic cattle and buffalo. A total of 423 clustered nucleotide sequences were identified in the samples, indicating significant taxonomic diversity: 11 phyla, 26 classes, 58 orders, 120 families and 272 genera. Distinct phylum-level patterns were observed, with Firmicutes predominating in healthy milk and a relative increase in Proteobacteria and Actinobacteriota in mastitic samples. At the genus level, Streptococcus and Lactococcus were predominant in mastitic samples, whereas Staphylococcus and Lactococcus were more prevalent in healthy milk. The results indicate that although overall microbial diversity was relatively consistent across groups, mastitis correlated with alterations in bacterial community composition, with notable differences between cattle and buffalo. This study suggests a potential association between SCM and microbial shifts; however, microbiome profiling cannot yet be recommended for diagnostic application. Clinical applicability requires validation in large-scale studies with individual-level sampling.",

Ingredient lists of 3,293 products across 16 food categories from eight major retail chains and one online market operating across T\u00fcrkiye were systematically screened for phosphorus-based additives between January and April 2025. Data collected included food category, additive type (E number/name), total additive count, and declaration methods of phosphorus-based additives. P-based additives were identified in 58.3% of products. The highest prevalence was observed in cereal products (91.4%), ice creams (82.5%), and coffee and chocolate drinks (79.6%). Fourteen different P-based additives were detected, with lecithin (E 322, 39.9%), phosphate-containing modified starches (20.5%), and diphosphates (E 450, 18.8%) being the most common. Riboflavin-5'-phosphate was frequently found in snacks, while ammonium phosphatide was prominent in confectionery, cereal products, and ice creams.

Its role in the vaginal epithelial barrier, however, remains unexplored. In this study, recombinant Amuc_1100 was expressed in a baculovirus-insect cell system and purified by immobilized metal affinity chromatography (IMAC). Purified Amuc_1100 exhibited concentration-dependent binding to recombinant TLR2 in ELISA. In VK2/E6E7 vaginal epithelial cells, Amuc_1100 treatment did not alter viability across the tested concentrations, confirming the absence of cytotoxicity. Western blot analysis demonstrated that Amuc_1100 treatment significantly increased the expression of tight junction-associated proteins, including Zonula Occludens-1 (ZO-1), Claudin-1 (CLDN-1), and Claudin-4 (CLDN-4), under basal conditions. Furthermore, stimulation with lipopolysaccharide (LPS) or zymosan A markedly reduced ZO-1 levels, whereas co-treatment with Amuc_1100 restored expression under both conditions.

Advances in manufacturing technology have dramatically broadened their application landscape, positioning them today as effective platforms for the oral delivery of pharmacologically active compounds, nutrients, and dietary supplements. Developing effective oral liposomal formulations, however, demands more than empirical optimization. It requires a strategy that simultaneously accounts for the complex physiological environment of the gastrointestinal (GI) tract, the physicochemical profile of the encapsulated payload, and the practical realities of scalable production. This work presents an integrative framework that unifies four critical decision-making axes: the Biopharmaceutics Classification System (BCS), Lipinski's Rule of Five, log\u2009P assessment and production process constraints. By mapping BCS categories onto specific GI absorption mechanisms, this framework enables the rational engineering of liposome architecture and properties to actively exploit physiological uptake routes. If the approach is effectively applied, liposomal carriers can achieve bioavailability enhancement that is to some degree independent of the payload's intrinsic membrane permeability and markedly less susceptible to food-effect interference compared to conventional oral formulations. Critically, aligning payload BCS class and log\u2009P with manufacturing feasibility supports the rational selection of production methods and excipient systems, striking a calibrated balance among encapsulation efficiency, release kinetics, physicochemical stability, and scale-up practicality. The power of this integrated approach is illustrated through two contrasting compounds, vitamin C (highly hydrophilic, BCS Class I) and vitamin D (highly hydrophobic, BCS Class IV), representing opposite ends of the physicochemical spectrum. These case studies demonstrate that tailoring liposome composition and processing conditions to the specific payload profile and GI physiological context can yield meaningful, nutritionally relevant gains in oral bioavailability for both hydrophilic and lipophilic molecules. This framework provides a scientifically rigorous and industrially actionable foundation for the rational development of next-generation oral liposomal formulations, systems that are not only mechanistically optimized but also commercially viable, ultimately contributing to improved therapeutic and nutritional health outcomes.",

BYM's antioxidant potential, prebiotic status, anti-inflammatory, hypoglycemic, antibacterial and anticancerous properties help it to combat a myriad of diseases. The antinutritional compounds present in BYM such phytic acid, tannins, polyphenols, and amylase inhibitors limit the absorption of minerals because they form complexes with dietary minerals like calcium, zinc, magnesium, and iron and make them inaccessible for absorption. Various processing methods like dehulling, soaking, heating, gamma irradiation, cold plasma processing, fermentation might enhance the nutritional and technological functional qualities of BYM. The bioactives in BYM can improve their bioavailability, in vitro digestibility, efficiency, structural modification and stability by biological processing techniques such as germination and fermentation employing microbial strains. BYM straw's high cellulose and hemicellulose percentage makes C5 and C6 sugars accessible for bioconversion into bioethanol.",

As the body's most accessible organ and the most frequent site of radiation injury, the skin represents a promising interface for monitoring exposure. Using colonized human skin equivalents (coHSE; 0 Gy n\u2009=\u20098, 1 Gy n\u2009=\u20096, 4 Gy n\u2009=\u20096) and mice (n\u2009=\u20096/group) models, we performed multi-omic profiling, integrating metabolomics, lipidomics, and metagenomics, on skin swab samples collected after exposure to 0, 1, or 4 Gy of x-rays. We identified two distinct metabolite panels: one discriminating irradiated from non-irradiated skin, and another distinguishing dose-specific response. These panels included conserved radiation-responsive metabolites (e.g., uric acid, xanthine, taurine) and skin-specific markers associated with barrier integrity (e.g., proline, arginine). Diacylglycerol network enrichment and shifts in radioprotective microbial taxa, including Lachnospiraceae and Lactobacillales, further supported a repair-driven molecular response. These data support the feasibility of skin swab signatures for non-invasive exposure classification, providing a molecular and microbial framework for skin based monitoring measure development and motivating validation in human cohorts for real-world biodosimetry.",

This study examined nine commercial PBMAs, focusing on protein digestibility and iron dialyzability. In vitro protein digestibility ranged from 81 to 96%, comparable to meat (86-90%), and was highest in protein concentrates and isolates (97-99%). Extrusion conditions (150-750\u00a0rpm, 100-160\u00a0\u00b0C) had minimal impact on digestibility but significantly affected texture and sensory properties. Dialysable iron in PBMAs was lower (2-5%) than in fungi-based products (15-32%) and meat (2-40%), though PBMAs had higher total iron content. Iron fortification using ferrous citrate, fumarate, sulphate and ferric pyrophosphate yielded dialysable iron values of 1.9-3.4%. These findings provide valuable insights into the nutritional composition of PBMAs and highlight opportunities to optimize processing for improved iron bioavailability.",

These compounds are directly relevant to human health, and their impact is influenced by structural diversity. The chemical composition of pectins varies according to botanical origin and is shaped by extraction and modification processes. Such structural differences determine both technological functionality and a range of bioactive properties, establishing pectins as potent dietary fibers with systemic health effects. Modified pectins exhibit immunomodulatory and anticancer activities through mechanisms including receptor interactions and modulation of key signaling pathways. In vivo studies further demonstrate their roles in regulating metabolism and in supporting gut barrier integrity. A critical aspect of pectin bioactivity involves promoting symbiotic interactions within the gut microbiota, increasing microbial diversity, and stimulating the production of beneficial metabolites, including short-chain fatty acids. Translational research, including clinical trials, has confirmed practical benefits for gastrointestinal management and metabolic health, and has highlighted the utility of pectins as adjuvants in pharmaceutical and nutritional formulations. This chapter highlights the link between pectins and the intersection of food science, nutrition, and biomedicine, emphasizing their potential as multifunctional ingredients for innovative health strategies.",

The quality of protein depends on the content and digestibility of indispensable amino acids, which are shaped by molecular structure, food matrix interactions and processing. These factors influence amino acid bioavailability, digestion rates and metabolic outcomes. This work provides an overview of protein digestion, highlighting the influence of amino acid sequence, folding, \u03b2-sheet prevalence, disulfide crosslinking, aggregation and interactions with anti-nutritional factors on enzymatic accessibility and hydrolysis. Particular attention is given to plant-derived proteins and meat analogues, the digestibility of which is often modulated by intrinsic structural characteristics and complex matrix effects. Food processing has a dual effect, as mild treatments enhance proteolysis through unfolding and improved solubility, whereas harsh treatments cause aggregation, cross-linking, racemization and modifications that hinder enzyme access. This chapter covers\u00a0in vitro digestion models, including the standardized static INFOGEST model, as well as semi-dynamic, and dynamic models. It details their uses, advantages and disadvantages for evaluating protein digestibility and nutritional value. Advanced tools such as high-resolution mass spectrometry and peptidomics help to characterized digestion products and offer a better understanding of how hydrolysis influences functionality and safety implications. The chapter also addresses protein quality metrics such as Digestible Indispensable Amino Acid Score, the challenges associated with them, and the need for a comprehensive framework to assess the nutritional and health impacts of alternative and novel plant proteins.",

The human gut microbiota, with its complex enzymatic potential, converts dietary substrates into a wide range of bioactive molecules, including short-chain fatty acids, vitamins, neuroactive compounds, and polyphenol-derived metabolites that influence host metabolism, immunity, and neurological functions. Advances in microbial genomics, systems biology, and synthetic biology now allow the design of fermentation processes and engineered microbial strains capable of producing specific metabolites with improved bioavailability and tailored health effects. Precision fermentation integrates traditional microbial fermentation with genome editing, metabolic flux optimisation, and AI-assisted pathway design to achieve predictable yields of vitamins, polyphenols, bioactive peptides, and long-chain polyunsaturated fatty acids. These innovations create opportunities to develop functional foods, nutraceuticals, and personalized nutrition strategies that match metabolite profiles to an individual's microbiome composition.

Here, we applied an integrative multi-omics strategy combining untargeted fecal metabolomics, shotgun metagenomics, mouse liver bulk RNA sequencing, and reanalysis of publicly available human hepatic single-cell and bulk transcriptomic datasets to characterize alcohol exposure-associated gut-liver immunometabolic features. In a mouse model of acute ethanol-induced liver injury, fecal metabolomic and metagenomic profiling revealed marked alterations in microbial functional potential and fecal metabolic composition, identifying six convergent metabolic pathways across fecal multi-omics layers, including nucleotide metabolism, the pentose phosphate pathway, histidine metabolism, glycerophospholipid metabolism, glycine/serine/threonine metabolism, and the phosphotransferase system. Reanalysis of human ALD single-cell transcriptomes showed hepatocyte-enriched activity patterns for several corresponding pathways, suggesting potential pathway-level associations between fecal metabolic alterations and hepatic transcriptional responses. Integrative transcriptomic analysis further identified a ten-gene hepatocyte-associated signature, comprising LRG1, ORM1, ORM2, TAT, HP, FGB, FGG, ITIH3, NNMT, and AGT, which was associated with pathway activity and showed consistent upregulation across acute ethanol-induced liver injury and human ALD/AH transcriptomic datasets. In an external human cohort, this signature stratified patients into exploratory molecular subgroups with distinct metabolic pathway activities and clinical outcome distributions. Collectively, these findings provide a hypothesis-generating multi-omics framework for investigating alcohol-related liver injury and support further validation in chronic ethanol exposure models and functional studies.",

This study aimed to develop and validate a nomogram for predicting sarcopenia risk in Chinese patients with CKM syndrome. Data were derived from the China Health and Retirement Longitudinal Study (CHARLS) and an independent hospital dataset. The CHARLS 2015 dataset was split into a training set and an internal validation set; the CHARLS 2011 dataset served as the external validation set; and inpatients from Guangdong Provincial Hospital of Chinese Medicine constituted the hospital validation set. Sarcopenia was diagnosed according to the 2025 Asian Working Group for Sarcopenia criteria. Least absolute shrinkage and selection operator (LASSO) regression combined with multivariable logistic regression was used for predictor selection and model development. Model performance was evaluated by discrimination, calibration, and decision curve analysis (DCA). Nine predictors were identified: age, smoking status, high-density lipoprotein cholesterol, triglycerides, uric acid, C-reactive protein, hemoglobin, chronic obstructive pulmonary disease, and chronic liver disease. The model achieved area under the curve values of 0.817, 0.808, 0.800, and 0.834 in the training, internal validation, external validation, and hospital validation sets, respectively. Calibration was satisfactory in development cohorts (p\u202f>\u202f0.05), with some calibration drift in external populations. DCA confirmed clinical utility across all datasets. The developed nomogram incorporating nine accessible predictors demonstrated robust discrimination and clinical applicability for sarcopenia risk assessment in Chinese CKM patients, supporting its use in early screening and individualized intervention.",

While reduced anthelmintic efficacy has been reported in humans, frequent reinfection and the lack of a vaccine highlight the need for alternative control strategies across species. In pigs, fermentable dietary fibers have been shown to enhance type 2 immune responses and mucosal barrier function and may represent a complementary strategy for parasite control. Here, we investigated the effects of a fermentable fiber diet in pigs infected with the parasite Ascaris suum (A. suum). Weaned pigs were fed either a diet enriched with fermentable fibers (HFD) or a control diet low in fermentable fibers (LFD). Four weeks after initiating supplementation, pigs were infected with A. suum eggs and maintained on the respective diets for an additional five weeks. HFD supplementation did not affect worm burden but significantly reduced worm size. This was associated with enhanced systemic and mucosal type 2 immune responses. Small intestinal Th2 responses, goblet cell expansion and the production of the anti-helminth effector molecules Arg1 and RELM-\u03b2 were increased, along with elevated peripheral eosinophil counts. Hence, dietary supplementation with HFD promoted innate and adaptive Th2 responses in A. suum infected pigs leading to impaired parasite development. These findings suggest that fermentable dietary fibers such as inulin and sugar beet pulp can influence infection dynamics at both the host and parasite levels.",
        "42558378": "ID: 42558378\nTitle: Extracellular vesicles from pasteurized Akkermansia muciniphila ameliorate inflammatory bowel disease through suppression of STING-driven inflammatory signaling.\nAbstract: Akkermansia muciniphila (A. muciniphila) has shown considerable potential in maintaining intestinal barrier homeostasis and regulating host inflammatory responses, both of which are commonly disrupted in inflammatory bowel disease (IBD). However, the therapeutic application of live A. muciniphila in IBD remains controversial. Interestingly, A. muciniphila-derived extracellular vesicles (AEVs) have been reported to improve intestinal barrier function, immune status, and gut microbiota composition, and may exert superior efficacy in IBD. In parallel, pasteurized A. muciniphila has been shown to retain, or even enhance, beneficial bioactivity compared with the live bacterium in certain disease settings. Here, we investigated whether extracellular vesicles derived from pasteurized A. muciniphila (PAEVs) preserve or further enhance the anti-inflammatory and barrier-protective effects of the parental bacterium. A dextran sulfate sodium (DSS)-induced mouse model of colitis was used to evaluate the therapeutic effects of PAEVs and AEVs. Disease severity, body weight loss, colonic histopathology, inflammatory cytokine expression, intestinal barrier integrity, inflammatory signaling pathways, and gut microbiota composition were assessed. PAEVs markedly attenuated DSS-induced colitis, as evidenced by reduced weight loss, improved colonic histology, decreased levels of TNF-\u03b1, IL-6, and IFN-\u03b3, and enhanced tight junction proteins. By contrast, AEVs improved only limited parameters, including Occludin expression and TNF-\u03b1 levels. Mechanistically, PAEV-mediated protection may be associated with suppression of the STING/I\u03baB/NF-\u03baB signaling axis and remodeling of the gut microbiota. These findings indicate that PAEVs effectively alleviate experimental IBD by enhancing tight junction proteins, suppressing some inflammatory cytokines, and modulating gut microbiota composition. Compared with AEVs, PAEVs exhibit broader protective effects, suggesting that extracellular vesicles derived from pasteurized A. muciniphila may represent a promising postbiotic strategy for IBD intervention. Importantly, this study offers the first systematic comparison of extracellular vesicles derived from live and pasteurized A. muciniphila, highlighting PAEVs as a distinct and potentially more effective postbiotic vesicle formulation for IBD intervention.",

Increasing evidence highlights the role of the gut-brain axis (GBA) and probiotic-derived short-chain fatty acids (SCFAs) in modulating neuroinflammation and disease progression. This study investigated the neuroprotective potential of SCFAs produced by Lactiplantibacillus plantarum C10 in a rotenone-induced PD zebrafish model. SCFA-producing lactic acid bacteria were isolated from traditionally fermented cabbage (sauerkraut), and the most promising isolate was identified as L. plantarum C10 using morphological, biochemical, phylogenetic, and 16S rRNA gene sequencing analyses. Fermentation conditions were optimized to maximize SCFA production, and the metabolites were characterized using Fourier-transform infrared spectroscopy (FTIR) and high-performance liquid chromatography (HPLC). Antioxidant activity was evaluated using DPPH and ABTS assays. Developmental toxicity was assessed in zebrafish embryos, followed by therapeutic evaluation in rotenone-induced adult zebrafish through behavioural, biochemical, molecular, and histopathological analyses. L. plantarum C10 exhibited strong probiotic characteristics, including antimicrobial activity, acid and bile tolerance, homofermentative metabolism, and extracellular polysaccharide production. Optimized fermentation significantly enhanced SCFA-associated metabolite production, while FTIR and HPLC confirmed the presence of fermentation-derived organic acid metabolites. The metabolites demonstrated potent antioxidant activity and showed minimal developmental toxicity up to 30 mg/mL in zebrafish embryos. In the rotenone-induced PD model, C10-derived SCFAs restored antioxidant enzyme activities, reduced oxidative stress, improved locomotor and cognitive performance, modulated genes associated with neuronal function, inflammation, the NRF2 signalling pathway, intestinal barrier integrity, and gut microbiota, and preserved normal brain and intestinal histoarchitecture. These findings demonstrate that L. plantarum C10-derived SCFA metabolites exert antioxidant, anti-inflammatory, and neuroprotective effects through modulation of the gut-brain axis. This study highlights the potential of probiotic-derived SCFAs as functional food-based therapeutic candidates for managing Parkinson's disease and associated gut dysbiosis.",

However, the intervention capability of B. adolescentis against different pathogenic bacteria remains unclear. In this study, we verified that B. adolescentis FS2-3 showed inhibitory effects against five common pathogenic bacteria, including Shigella dysenteriae CMCC 51,252, Klebsiella pneumoniae NCTC 13,440, Pseudomonas aeruginosa CMCC 10,104, Salmonella enteritidis CMCC 50,746, and Campylobacter jejuni CICC 22,936. To improve its intestinal colonization efficiency, we constructed double-layered multinucleated microcapsules (probiotic microcapsules) of B. adolescentis FS2-3 and evaluated their effects on bacterial enteritis induced by five representative foodborne pathogens. The in vitro experiments showed that the survival rate of B. adolescentis FS2-3 in the microcapsules was increased by 5.76 times compared with the unencapsulated strain. Additionally, the probiotic microcapsules significantly reduced intestinal tissue damage and inflammation in all enteritis mice, especially in Salmonella-infected mice. Specifically, the probiotic microcapsules reversed the abnormal bacterial composition by promoting the colonization of beneficial bacteria Bifidobacterium, Alloprevotella, and Lachnospiraceae. Furthermore, the probiotic microcapsules inhibited the overexpression of TLR-4 and reduced the expression of inflammatory mediators, including IL-1\u03b2, NF-\u03baB, and TNF-\u03b1. These findings provide new insights into the application of probiotic microcapsules in the treatment of enteritis.",

This study characterized and compared the pharmacokinetics of L-citrulline after intravenous (IV) and oral (PO) administration in healthy neonatal Holstein calves and evaluated associated amino acid responses and short-term clinical and laboratory tolerability. Six healthy male calves (2-4\u2009weeks old) received a single 150\u2009mg/kg dose of L-citrulline as extemporaneously prepared 5% (w/v) IV and 10% (w/v) PO formulations in a randomized 2-period crossover design with a 7-day washout. Blood samples were collected pre-dose and up to 48\u2009h post-dose. Plasma amino acids were quantified by LC-MS/MS, and pharmacokinetic parameters were estimated using non-compartmental analysis. After IV administration, the highest observed total plasma L-citrulline concentration was detected at the first post-dose sampling time, 5\u2009min after bolus administration (Cpeak 2213\u2009\u00b1\u2009629\u2009\u03bcmol/L; range, 1329-2830\u2009\u03bcmol/L).

VDR is a high-affinity intracellular binding protein for the most active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25D). Early biochemical and molecular studies established VDR as a member of the nuclear receptor superfamily, functioning as a transcription factor that heterodimerizes with the retinoid X receptor and binds vitamin D response elements to regulate gene expression. Since the cloning of the VDR gene in the 1980s, characterization of its structural domains, and identification of co-regulators significantly advanced understanding of its genomic mechanisms of action. Over the past several decades, research has expanded the scope of VDR biology beyond classical calcium and phosphate metabolism. Genome-wide binding analyses and transcriptomic studies have revealed extensive VDR cistromes and context-dependent gene networks across diverse tissues. These advances have positioned VDR as a key factor linking vitamin D availability to tissue-specific outcomes. Despite substantial progress, fundamental questions remain including mechanisms governing tissue-specific VDR actions, integration of genomic signaling pathways, and role of VDR in complex diseases such as cancer, autoimmune disorders, and aging. Additionally, how VDR function is modulated by chromatin context, metabolic state, and the microbiome remains incompletely understood. Here, we summarize what is known about these actions of VDR and its history of discovery. Addressing these questions will be essential for translating mechanistic insights into improved therapeutic strategies targeting the vitamin D axis.",

This study investigated how fructooligosaccharide (FOS) treatment affects microbial fermentation, intestinal function, inflammation, and hepatic bile acid synthesis in G. lamblia-infected gerbils. Gerbils were divided into four groups: uninfected control, infected control, uninfected and FOS-treated, and infected and FOS-treated. Cecal short-chain fatty acids (SCFAs), intestinal disaccharidase activities, serum and intestinal cytokines, and hepatic expression of Cyp7a1 and Cyp8b1 were analysed. Giardia infection increased cecal acetate, reduced butyrate, elevated serum TNF-\u03b1, and increased hepatic Cyp7a1 expression. FOS supplementation increased cecal propionate and other SCFAs and elevated IL-10 levels in serum and intestinal tissue. Notably, FOS reduced intestinal maltase activity regardless of infection status, without affecting lactase activity. Together, these data indicate that giardiasis alters microbial fermentation and inflammatory responses, whereas FOS supplementation primarily promotes a more regulatory immune profile, characterized by increased IL-10 levels, alongside shifts in microbial fermentation, without directly modifying hepatic bile acid-related gene expression. These findings highlight complex diet-microbiota-host interactions during intestinal parasitic infection and support further mechanistic studies.",

Emerging evidence suggests that TRD may extend beyond monoaminergic dysfunction and may involve dysregulation of the HPA axis, neuroinflammation, impaired neuroplasticity, and disruption of the gut-brain axis (GBA). Gut dysbiosis has been associated with treatment resistance through alterations in monoamine turnover, immune signalling, intestinal barrier integrity, and drug-microbiome interactions affecting antidepressant bioavailability. This review integrates emerging evidence supporting targeted modulation of the GBA as a mechanistically informed strategy for TRD. Specific microbial strains (e.g., Christensenella minuta, Akkermansia muciniphila, Bifidobacterium breve CCFM1025), microbial metabolites (e.g., indole-3-propionic acid, indole-3-lactic acid, anserine), and phytochemicals (e.g., curcumin, matrine, salidroside) are discussed for their proposed roles in modulating neuroendocrine signalling, neuroinflammation, and synaptic plasticity. The review also highlights emerging peripheral biomarkers, including the kynurenine/tryptophan ratio, serum metabolomics, and lymphocyte serotonin transporter clustering, as candidate tools for stratified psychiatry. Most of the evidence discussed in this review comes from animal studies, in vitro systems, and computational analyses, while direct evidence in patients with treatment-resistant depression remains limited. These findings provide important mechanistic insights into gut-brain axis dysfunction but require further validation in human TRD populations. Biomarker-guided and endotype-based approaches targeting the gut-brain axis may offer a useful framework for future research, although their clinical utility has yet to be established.",

We characterized Se and Hg concentrations in tuna (Thunnus albacares) integrating stoichiometric and probabilistic analyses to reframe Hg risk. [Se:Hg] and HBVSe values were uniformly protective across all samples, and Se and Hg accumulation were shown to be independent. A 2\u00d72 classification matrix, combining the EU regulatory Hg threshold (1.0 \u03bcg/g ww) with the [Se:Hg] stoichiometric threshold of 1, was applied to simultaneously assess regulatory compliance and selenoprotective status. All samples were in the protective quadrant, with Hg below the regulatory ceiling and Se in stoichiometric excess in every case. Monte Carlo simulations (n = 100,000) further demonstrated that tuna consumption contributes meaningfully to dietary Se adequacy for both Portuguese and Spanish adults. After correction for Hg-mediated Se sequestration (reducing theoretically bioavailable Se by a mean of 18.6%) median theoretically bioavailable Se intake remained at 25.0% and 14.4% of the Dietary Reference Value for Portugal and Spain, respectively. At typical Iberian consumption levels, tuna contributes meaningfully to dietary Se adequacy, with Se present in stoichiometric excess of Hg across all samples.",

Probiotics and dietary fibers have diverse bioactivities but are limited by poor stability and low bioavailability. Herein, a novel microcapsule system co-loading Ganoderma lucidum dietary fiber (GLDF) and Lactobacillus fermentum CECT5716 was constructed using whey protein (WP) and xanthan gum (XG) via hybrid spray drying-complex coacervation. Optimal WP-XG interaction (driven by electrostatic forces and hydrogen bonds) was achieved at pH\u00a03.75 and 5:1 mass ratio; microcapsules with 1:1 wall-to-core ratio showed the best performance, with 72.3% post-encapsulation probiotic viability and enhanced stability under simulated gastrointestinal conditions and storage. Animal experiments confirmed that the microcapsules effectively alleviated loperamide (LOP)-induced constipation in mice, associated with regulating gut microbiota, promoting short-chain fatty acids (SCFAs) production, inhibiting colonic inflammation, repairing intestinal tight junctions, and downregulating aquaporins. In conclusion, the microcapsules prepared in this study provide a feasible strategy for the efficient co-delivery of probiotics and dietary fibers, and the developed composite functional ingredient holds great application potential in the field of constipation prevention and treatment.",

CRC has been recognized as a consequence of microbial (such as F. nucleatum, E. coli (pks+ strains) biofilms, inflammatory signaling, and redox imbalance in the human gut. Hence, natural bioactive substances as a part of the daily diet are crucial for the downregulation of biofilm-mediated CRC. Dietary alkaloids, nitrogen-containing secondary metabolites, have been identified as potential chemotherapeutic agents that can inhibit biofilm formation through quorum-sensing inhibition, modulating the tumor microenvironment, including redox and inflammatory pathway regulation. The present review primarily focuses on the alkaloids' structure-function relationships, microbial biotransformation, and inhibition of pathogenic biofilms, through downregulation of NF-\u03baB, IL-6, STAT3-mediated inflammatory cascades, apoptosis, induction of autophagy, and balancing the redox-oxidative homeostasis. Further, the synergistic effect of alkaloids with dietary fiber, short-chain fatty acid (SCFA)-mediated synergy, and polyphenol compounds is essential for microbial-epithelial barrier activity and metabolic homeostasis regulation. However, the integration of dose windows, dietary patterns, and regulatory landscapes is essential to establish dietary alkaloids as a functional food in biofilm-mediated CRC prevention. Moreover, bioavailability of dietary alkaloids is a potential challenge, and nano-enabled delivery, specifically lipid and polymeric nano carriers, is considered for the controlled delivery, mucosal bioactivity, and reduced systemic exposure of alkaloid carriers for colon mucosa bioactivity. Overall, the integration of microbiome with dietary alkaloids as bioactive food components, to modulate biofilm and tumor micro-niches, underlines the translational potential of dietary alkaloids for CRC prevention.",

Its successful implantation during industrial fermentation varies significantly according to wineries and regions. This inconsistency frequently causes undesirable quality fluctuations and deterioration. However, their interactions with native microbiota has not been fully elucidated. This study deciphers microbiota and metabolite profiles during industrial Cabernet Sauvignon wine fermentations with different implantation percentage of commercial active dry yeasts (ADYs) through multi-omics. Strain-level implantation percentages of ADYs were found to differ significantly among the studied wineries. High-throughput sequencing further showed differences in fungal and bacterial community structures between different dominance of ADYs. Metabolome analysis showed that 291 non-volatile metabolites represented the variations between high (80%) and low (50%) implantation percentage of ADYs. These metabolites were mainly involved in 20 different pathways, such as amino acids synthesis, cutin, suberine and wax biosynthesis. Also, significant differences in aroma profiles were observed between high and low dominance samples. Correlation analysis among microorganisms, non-volatile and volatile profiles revealed the effect of the implantation of ADYs on both microbial communities interactions and the resulting metabolite profiles, and highlighted the pivotal role of key microorganisms in shaping characteristic aromas. This study enhances understanding of how ADYs implantations affect microbial communities and metabolite profiles in wines, providing insights into a microbial \"terroir\" of relevance to wine character and wine quality.",

This study systematically investigated the microbial drivers of organic acid metabolism across six sequential rounds (R1-R6) of heaped fermentation. A total of 24 organic acids were identified, including nine non-volatile organic acids (NVOAs) and 15 volatile organic acids (VOAs). HPLC analysis revealed that the total content of acetic acid and nine NVOAs increased significantly across rounds, rising from 29.35\u00a0g/kg in R1 to 66.40\u00a0g/kg in R6. Lactic acid was the most abundant NVOA, while acetic acid, isovaleric acid, and hexanoic acid were the primary volatile contributors. Co-occurrence network analysis identified 488 consistently correlated bacterial pairs that clustered into two distinct guilds. Guild 2, mainly comprising Virgibacillus, Kroppenstedtia, Oceanobacillus, and Bacillus, exhibited high abundance (47%-78%) across all rounds and was defined as the core bacterial guild. Spearman correlation analysis revealed that guild 2 was positively correlated with NVOAs (69.41%) but negatively correlated with VOAs (63.02%). Metagenomic analysis reconstructed seven key pathways involved in organic acid biosynthesis. Kroppenstedtia, Lentibacillus, Desmospora, and Oceanobacillus were identified the taxa harboring the genetic potential most frequently detected across multiple pathways, with Kroppenstedtia and Lentibacillus exhibiting the highest gene abundances. These findings provide a theoretical foundation for targeted regulation of organic acid content in sauce-flavor Baijiu production.",

Despite their favorable nutritional composition, they also naturally contain antinutritional factors such as phytic acid, that limit the absorption of micronutrients. This, coupled with the lower bioavailability of proteins as compared with meat, diminishes the biological and economic value of legumes. However, recent studies have shed a light on the power of fermentation to improve the protein profile of pulse and neutralize antinutritional compounds. In this review, we explore the benefits of legumes fermentation in depth, focusing on the role of microorganisms in enhancing the nutritional and sensory enhancement of legumes. Furthermore, we describe the properties and the microorganisms involved in the production of several craft-based fermented legumes typically consumed by non-Westernized populations, particularly delving into their effects on the gut microbiome and on the human health.",

However, accurate interpretation of the 16S rRNA gene survey requires specialized software and an algorithm to convert raw sequencing data into reliable taxonomic profiles. Given the existence of multiple bioinformatics pipelines varying in sequence aggregation strategies, reference databases, and filtering parameters, there is little to no consensus on best practices for LMF processing systems. In this study, we systematically assessed discrepancies in taxonomic composition, alpha diversity, and beta diversity across 32 combinations of bioinformatics workflows, based on eight widely used 16S rRNA pipelines and four taxonomic databases, applied to 16S rRNA gene sequences extracted from wheat milling environments (n\u00a0=\u00a0160). Weighted composite scores were used to select the top 10-performing workflow combinations for downstream analysis. Taxonomic assignments were broadly similar across workflows at the family and genus levels; however, genus-level diversity metrics were more sensitive to workflow choice. At the family level, diversity metrics were conserved across pipeline-database combinations (Chao1: 22.97\u00a0\u00b1\u00a02.20-24.92\u00a0\u00b1\u00a02.04; Shannon: 2.59\u00a0\u00b1\u00a00.19-2.74\u00a0\u00b1\u00a00.18; InvSimpson: 10.63\u00a0\u00b1\u00a01.25-11.27\u00a0\u00b1\u00a01.06; Bray-Curtis: 0.528-0.556; Jaccard: 0.557-0.582), whereas at the genus level both alpha and beta diversity exhibited wider ranges and larger dispersion (Chao1: 45.27\u00a0\u00b1\u00a05.68-50.20\u00a0\u00b1\u00a05.64; Shannon: 2.54\u00a0\u00b1\u00a00.24-2.73\u00a0\u00b1\u00a00.22; InvSimpson: 10.37\u00a0\u00b1\u00a01.4-11.03\u00a0\u00b1\u00a01.05; Bray-Curtis: 0.79-0.82; Jaccard: 0.79-0.80). Furthermore, ASV vs. OTU workflows were comparable across the evaluated metrics; however, ASVs showed numerically higher values for some genus-level measures than OTUs because they can resolve variation down to the single-nucleotide level, thereby retaining low-abundance features important for LMF safety. This work paves the way toward using bioinformatics and 16S pipelines to characterize sparse, low-density, and uneven samples in low-moisture environments.",

This review provides a critical synthesis of research between 2018 and 2025 on microbial composition, community dynamics, functional roles, safety risks, starter culture applications, and multi-omics characterisation of Jinhua ham fermentation, unified by precision fermentation as an organising framework. High-throughput sequencing has established that halotolerant bacterial genera, Staphylococcus, Psychrobacter, Halomonas, and Lactobacillus, and fungal communities comprising Aspergillus, Debaryomyces, Meyerozyma, and Penicillium undergo deterministic, physicochemically driven succession, with their enzymatic activities governing proteolysis, lipolysis, volatile compound formation, colour stabilisation, and the accumulation of biogenic amines, mycotoxins, and antimicrobial resistance genes (ARGs). Autochthonous starter cultures, including Staphylococcus xylosus, Lactiplantibacillus plantarum, and Penicillium aethiopicum, improve process controllability, safety, and sensory consistency, yet their mechanistic basis and validation remain incompletely established. Genomic and metabolomic approaches have generated datasets, but integrated metagenomics-metabolomics coupling, capable of linking microbial gene networks to flavour compound production, and metatranscriptomic characterisation of gene expression remain the unmet methodological needs. Five research directions are proposed: achieving species-level microbial resolution through long-read sequencing and longitudinal sampling; validating flavour-forming pathways through isotopic tracing and controlled inoculation; standardising analytical protocols for cross-study comparability; conducting starter culture and ARG safety validation; and developing low-salt fermentation strategies. Together, these directions define the research investment required to advance Jinhua ham production from empirical tradition to precision-engineered consistency.",

This study investigated whether temperature control aligned with bacterial succession could stabilize Huangjiu fermentation and shape fatty acid ethyl ester (FAEE) profiles. Sequential screening identified 28\u00a0\u00b0C in stage I, 28\u00a0\u00b0C in stage II, and 20\u00a0\u00b0C in stage III as the benchmark schedule for robust fermentation, yielding the highest ethanol retention, balanced physicochemical traits, and the best terminal sensory quality. Further refinement showed that additional cooling did not further improve overall fermentation stability, as reflected by ethanol retention, acidification control, and terminal sensory balance, but selectively redirected terminal aroma formation. In S3-15, additional stage III cooling increased long-chain FAEEs by 112.7%. Stage II cooling in S2-24 increased medium-chain FAEEs by 80.0%, whereas combined cooling in S2-20/S3-15 produced the strongest medium-chain FAEE enrichment. Combined cooling in stages II and III produced the strongest terminal ester retention, increased medium-chain FAEEs by 2.81-fold, and enhanced selected aroma-active esters at the end of fermentation. Among the sequenced schedules, bacterial community analysis showed that stage-resolved cooling altered the timing of lactic acid bacteria (LAB)-dominated succession, and S2-20/S3-15 showed the strongest bacterial community-volatile organic compound (VOC) association. These findings support biologically aligned temperature control as an evidence-based strategy for stabilizing Huangjiu fermentation and provide broader insight into temperature-microbiota coordination in mixed-culture cereal fermentations.",

However, how its micro-ecosystem evolves with cellar age and drives flavor formation remains unclear. Using Huangshui as a dynamic window, this study integrated metagenomics, metabolomics, and flavoromics to compare its temporal dynamics in new and old cellars over a complete fermentation cycle, systematically characterizing how cellar age is associated with the restructuring of the microbial community and metabolic functions of Huangshui, and how these changes are consistent with the flavor profiles observed in the final base liquor. The results showed that Huangshui from old cellars harbored a more diverse and stable microbial community, forming a syntrophic consortium of caproic acid-producing bacteria (Caproicibacterium, Caproiciproducens), syntrophic bacteria (Syntrophomonas), and methanogenic archaea (Methanosarcina), whereas new cellars were dominated by lactic acid bacteria (Acetilactobacillus). Metabolically, the old-cellar community exhibited a clear phase-dependent division. During the acid-producing phase, the TCA cycle, arginine biosynthesis, and pyruvate metabolism were preferentially activated to generate core precursors; during esterification, butanoate metabolism and acyl-CoA supply pathways were enhanced. This orderly shift was associated with higher concentrations of ethyl caproate and ethyl octanoate in old-cellar base liquor. Functional gene analysis revealed coordinated upregulation of chain-elongation, methanogenic, and acetate-activating pathways in old cellars. Network analysis revealed a tightly coupled caproic acid-producing co-occurrence module in old cellars, which was not observed in new ones. Together, these findings suggest that Huangshui may serve as a rapid proxy for assessing both the fermentation status and the maturity level of the cellar. This work identifies potential bioaugmentation targets to accelerate flavor development in new cellars and provides a theoretical basis for the precise micro-ecological management of strong-aroma Baijiu quality.",

This study aimed to evaluate the respective contributions of alfalfa (Medicago sativa L.; AL) growth stage and phyllosphere microbiota to fermentation products, bacterial community diversity, co-occurrence networks, and functional potential using high-energy electron beam irradiation and microbiota transplantation methods. Alfalfa was harvested at the initial-flowering and full-flowering stages. The irradiated initial-flowering (AL1) and full-flowering (AL2) alfalfa were inoculated with 2\u00a0mL of phyllosphere microbiota inoculum eluted from the initial-flowering (AL1_IF, AL2_IF) and full-flowering (AL1_FF, AL2_FF) alfalfa, respectively. Chopped alfalfa (200\u00a0g fresh weight) was fermented in laboratory-scale plastic bags. Triplicate samples from each treatment were collected after 3 and 60\u00a0days of fermentation. After 60\u00a0days, growth stage exerted stronger effects on fermentation products, while phyllosphere microbiota significantly influenced bacterial community structure and co-occurrence network patterns. On day 60, AL1 groups exhibited higher (P\u00a0<\u00a00.05) acetic acid concentrations, pH, and proportions of potentially pathogenic bacteria than AL2 groups. Lactobacillus and Weissella dominated the bacterial community, with Pediococcus remarkably enriched in AL2 groups on day 60. Functional prediction indicated that glycolysis and lactate dehydrogenase were obviously upregulated during fermentation, and lactic acid was synergistically produced via both homolactic and heterolactic pathways. For practical production, initial-flowering alfalfa can be optimized by wilting or substrate supplementation, while full-flowering alfalfa benefits from inoculation with Lactobacillus and Pediococcus. These findings clarify the independent roles of growth stage and eluted phyllosphere microbiota and provide precise strategies for high-quality fermented alfalfa production.",

This study investigated the mechanisms by which Bifidobacterium animalis subsp. lactis Probio-M8 fermented milk enhances digestive efficiency and protects against dextran sulfate sodium-induced colitis in rats. FM8 supplementation promoted weight gain without excessive adipogenesis, elevated leptin levels, and amplified sucrase, lactase, aminopeptidase, and lipase activities, outperforming conventional fermented milk. Metagenomic analysis revealed microbial restructuring with Corynebacterium glutamicum and Bifidobacterium animalis enrichment, and increased short-chain fatty acids.Untargeted metabolomics identified FM8-responsive metabolites, including p-hydroxybenzaldehyde and indole-3-carboxaldehyde, linked to anti-inflammatory pathways. In dextran sulfate sodium-challenged rats, FM8 pre-administration attenuated colitis severity by reducing disease activity index scores, normalizing colon histology, and suppressing interleukin (IL)-6 and IL-17 while elevating IL-10 and IL-22. Mechanistically, FM8 enriched Bifidobacterium animalis and butyrate levels, which inversely correlated with mucosal injury and pro-inflammatory cytokines. These findings demonstrate that FM8 enhances gastrointestinal health through tripartite microbiota-metabolite-immune interactions, highlighting its functional potential for metabolic optimization and colitis prevention.",

Within these multispecies systems, lactic acid bacteria (LAB) function as ecological and metabolic cornerstones. However, the mechanisms underlying LAB-mediated community stability remain insufficiently understood. This review synthesizes current knowledge on microbial competition, cross-feeding, and community homeostasis to evaluate the ecological contributions of LAB. We compare the metabolic roles of LAB in SynComs and natural ecosystems, highlighting competitive strategies, including acidification and antimicrobial production, as well as lactate-centered syntrophic interactions. As central metabolic hubs, LAB facilitate the division of labor by transforming excess metabolic outputs into shared resources, thereby reducing metabolic inefficiencies. We further examine how functional redundancy and metabolic coupling contribute to community resilience and stability. The review also discusses emerging applications of SynComs in gut health, particularly inflammatory bowel disease (IBD), and industrial fermentation processes. We conclude that the integration of multi-omics approaches with predictive modeling will be critical for the rational design and programmable regulation of stable microbial consortia. Furthermore, this review proposes a unified hierarchical framework for understanding the stability of LAB-mediated SynComs. By integrating competition-driven colonization, cooperation mediated through cross-feeding interactions, and multidimensional homeostatic mechanisms, the framework bridges fundamental ecological theory with applied microbiome engineering. The proposed framework is primarily applicable to LAB-centered SynComs associated with food fermentation systems, acidic environments, and lactate-driven metabolic networks.",

Age-related dysfunction of endothelial nitric oxide synthase (eNOS), compounded by increased oxidative stress, creates a vicious cycle of oxidative-nitrosative imbalance, leading to chronic inflammation and arterial stiffness. The Dietary Approaches to Stop Hypertension (DASH) diet was developed as a primary intervention to restore NO balance by protecting endogenous pathways and supplying alternative nitrate-nitrite-NO precursors. However, its cardiovascular benefits are often diminished by age-related alterations in nitrate metabolism and the extensive use of multiple medications in the elderly. Thus, while restoring balance remains a key therapeutic goal, future clinical strategies must evolve from broad dietary recommendations to more personalized, precise nutritional approaches, considering the unique physiological and pharmacological challenges faced by older adults.",

In contrast to heart failure with reduced ejection fraction (HFrEF), few disease-modifying therapies exist for HFpEF, reflecting differences in pathophysiology. Low fermentable fiber (FF) intake, gut dysbiosis, and depletion of short-chain fatty acids (SCFAs), microbial metabolites central to immune, metabolic, and vascular homeostasis, are increasingly linked to the pathophysiology of HFpEF. Here, we synthesize preclinical and clinical evidence on FF and SCFAs and evaluate their therapeutic relevance to HFpEF. Preclinical studies demonstrate that FF supplementation or direct SCFA administration improves cardiometabolic function and attenuates cardiac remodeling through SCFA receptor signaling, enhanced nitric oxide bioavailability, reduced inflammation, and metabolic support of the energy-starved failing heart. Supporting the translational relevance of these findings, a systematic review of 27 human randomized controlled trials showed that FF interventions exert microbiome-mediated effects, enriching SCFA-producing taxa and augmenting fecal and circulating SCFA levels, while improving insulin sensitivity and reducing abdominal adiposity and LDL cholesterol. Direct SCFA supplementation increases SCFA availability and provides modest metabolic benefits, including reduced adiposity and liver fat. However, its effects are inconsistent. Collectively, these findings provide a mechanistic and translational rationale for FF-based interventions in HFpEF. To date, no clinical trials have evaluated the effects of FF on HFpEF-specific outcomes. Clinical studies are therefore needed to determine whether increasing FF intake can improve symptoms, cardiac function, and disease progression in HFpEF.",

This review summarizes current understanding of how the gut microbiota influences iron metabolism, vitamin synthesis-particularly vitamin B12-and immune modulation, all of which are key factors in the pathogenesis of anemia. We explore the mechanisms by which dysbiosis of the gut microbiota contributes to anemia development, including disruptions in nutrient absorption and inflammatory responses.

These diseases are commonly associated with insulin resistance and abnormal lipid metabolism, and increasing evidence indicates that immune imbalance and chronic low-grade inflammation are involved in their development. Natural polysaccharides are important bioactive components derived from plants, fungi, algae, and other natural sources. Current evidence supporting their beneficial effects in metabolic diseases is predominantly preclinical, mainly from cell-based and animal studies, while clinical evidence remains limited and heterogeneous. Natural polysaccharides have attracted interest as candidate bioactive compounds because some preparations have shown immunomodulatory and metabolic regulatory activities in experimental models. Their activities are closely related to structural features, including monosaccharide composition, glycosidic linkage types, molecular weight, branching structure, and chemical modification. Current preclinical evidence suggests that natural polysaccharides may alleviate metabolic inflammation by regulating macrophage polarization, suppressing pro-inflammatory cytokine production, modulating MAPK, NF-\u03baB, AMPK, and related signaling pathways, and reshaping the gut microbiota-immune axis. These compounds may help improve several pathological features of metabolic disorders, such as insulin resistance, abnormal lipid metabolism, inflammatory injury, and tissue dysfunction. However, several challenges still limit their translation, including unclear structure-activity relationships, inconsistent preparation standards, limited bioavailability, and insufficient well-designed clinical trials. Therefore, this review provides an overview of the natural sources, structural properties, immunomodulatory actions, and therapeutic prospects of natural polysaccharides in metabolic diseases, with a focus on their involvement in immune regulation and metabolic inflammation.",

Nevertheless, clinical outcomes remain highly heterogeneous, with many patients experiencing primary or acquired resistance and/or immune-related adverse events (irAEs) that impair their quality of life and treatment adherence. The human microbiome, particularly in the gut and oral compartments, has emerged as a critical modulator of systemic antitumor immunity and a promising noninvasive predictive biomarker for ICI efficacy and toxicity. This narrative review synthesizes the current evidence on microbiome composition, diversity, and function in patients with LC receiving ICIs as monotherapy, dual blockade, or in combination regimens, as well as clinically relevant biomarkers associated with treatment response and toxicity. Higher gut microbial alpha diversity and enrichment of beneficial taxa (e.g., Akkermansia muciniphila, Faecalibacterium prausnitzii, and certain Firmicutes) are consistently linked to improved progression-free survival (PFS) and overall survival (OS), mediated by microbial metabolites such as short-chain fatty acids and inosine, which enhance T-cell priming, tumor microenvironment remodeling, and gut-lung axis communication. Microbiome-disruptive exposures, particularly antibiotics and proton pump inhibitors (PPIs), induce dysbiosis and are strongly associated with poorer survival outcomes. Mechanistic insights from preclinical models and clinical cohorts, alongside clinical confounders, underscore the complementary role of the microbiome relative to established markers such as programmed death-ligand 1 (PD-L1) and tumor mutational burden. Prospective standardization of metagenomic profiling and microbiome-modulating interventions represents a key next step in translating these findings into personalized immunotherapy strategies for LC.",

This review systematically examines the phytochemistry, pharmacokinetics, and anti-diabetic mechanisms of this botanical drug. Over 230 metabolites, including flavonoids, triterpenoids, and lignans, have been identified from EA. Pharmacokinetic studies remain limited; computational predictions suggest that some metabolites may exhibit oral bioavailability, but classical pharmacokinetic parameters have not been experimentally determined for any EA metabolite. Mechanistic studies demonstrate that EA exerts anti-diabetic effects through multiple experimentally validated pathways: (i) inhibiting alpha-glucosidase activity to delay intestinal glucose absorption; (ii) activating the peroxisome proliferator-activated receptor gamma and phosphatidylinositol 3-kinase/protein kinase B signaling pathways to ameliorate insulin resistance; (iii) modulating gut microbiota composition and increasing short-chain fatty acid production; (iv) suppressing the advanced glycation end products-receptor for advanced glycation end products axis along with the nuclear factor kappa B and mitogen-activated protein kinase inflammatory pathways to alleviate oxidative stress and inflammatory responses; and (v) regulating diacylglycerol acyltransferase activity to improve lipid metabolism. Preclinical studies indicate that EA reduces blood glucose and improves markers of diabetic nephropathy and retinopathy. Clinical studies of EA-containing formulations report reductions in fasting blood glucose and urinary protein. However, the clinical evidence remains limited by small sample sizes, lack of rigorous controls, and multi-botanical drug compositions that preclude attribution of effects to individual components.

This study aimed to evaluate the individual and combined effects of humic acid and probiotics on growth performance, carcass characteristics, immune parameters, caecal bacterial populations (Escherichia coli, Salmonella spp., and Lactobacillus spp.), and the financial feasibility of broiler production. A total of 195 one-day-old Lohmann Meat (Indian River) broiler chicks were allocated in a completely randomized design with five dietary treatments and 3 replicates of 13 birds each. Dietary treatments were as follows: a basal diet (control), a basal diet with 0.05% humic acid, a basal diet with 0.10% humic acid, a basal diet with 0.02% probiotics, and a basal diet containing both 0.05% humic acid and 0.02% probiotics. Dietary inclusion of humic acid or probiotics did not significantly affect (p > 0.05) body weight gain, feed intake, or feed conversion ratio at 28\u2009days (market age), but significant improvements were observed at 7, 14, and 21\u2009days. However, the combined supplementation of 0.05% humic acid and 0.02% probiotics significantly improved several carcass traits (thigh, drumstick, back, wing, and liver weights), reduced caecal pathogenic bacteria (E. coli and Salmonella spp.), increased beneficial Lactobacillus spp., and enhanced immune parameters (higher lymphocyte percentage and lower white blood cell counts) compared to the control (p < 0.05). Hematological values remained within normal physiological ranges across all treatments. Economic analysis revealed that the combined supplementation group recorded the highest net present value (176.44 USD), internal rate of return (43.51%), and benefit-cost ratio (1.22), and the shortest payback period (1.93\u2009years). Overall, this study demonstrated that dietary supplementation with humic acid and probiotics, particularly in combination, improved carcass traits, reduced pathogenic bacterial loads, enhanced selected immune parameters, and increased economic returns without affecting growth performance at 28\u2009days.",

This work aims to reveal the distinct features among Feng-flavor Daqu (FXDQ) and the 3 main flavor types of Baijiu Daqu (Light-, Luzhou-, Sauce-flavor Daqu). FXDQ exhibited lower moisture content, and the higher acidity, esterifying power, liquefaction capacity. Microbially, Bacillus and Actinomyces dominated the bacterial community, whereas Saccharomycopsis was the predominant fungal genus. Across the four Daqu, 130 volatile compounds were detected and 16 of these were identified as key discriminators. Strong correlations were identified among the microbiota, physicochemical properties, enzyme activities, and volatile compounds. Moreover, PICRUSt2 was utilized to predict enzymes associated with the production of some important aroma compounds. These findings enhance our understanding of Daqu, particularly providing deeper insights into the unique characteristics of Feng-flavor Daqu, and offer a scientific basis for optimizing Daqu production processes.",

In this study, a polysaccharide fraction (Q60E) was isolated from SE-treated H. erinaceus. Structural analysis revealed that Q60E (M w , 8.89\u00a0\u00d7\u00a0104\u00a0g/mol) was a mannogalactoglucan, featuring a backbone of \u21923)-\u03b1-Manp-(1\u2192, \u21926)-\u03b2-Glcp-(1\u2192, \u21923,6)-\u03b2-Glcp-(1\u2192, \u21923)-\u03b1-Glcp-(1\u00a0\u2192\u00a0and \u21924,6)-\u03b2-Galp-(1\u00a0\u2192\u00a0linkages with side chains of \u21924)-\u03b1-Glcp-(1\u00a0\u2192\u00a0and terminal \u03b2-Glcp-(1\u00a0\u2192\u00a0residues. Based on the shape factor \u03c1 (1.71) and the Mark-Houwink-Sakurada parameter (exponent \u03b1, 0.51), Q60E adopted a random coil conformation in aqueous solution. In vitro fermentation studies demonstrated that Q60E modulated gut microbiota by promoting beneficial genera (Lactobacillus, Lachnospira and Bifidobacterium) while suppressing pathogenic Fusobacterium. Furthermore, Q60E fermentation additionally enhanced the acetic acid and total SCFAs production, underscoring its prebiotic capacity. These findings highlight the potential of the mannogalactoglucan from SE-pretreated H. erinaceus as effective prebiotics for gut health.",

Mulberry leaves (ML) and distillers' grains (DG) are by-products generated from agriculture and industry in Sichuan, China. Characterized by abundant output and favorable nutritional composition, two materials can be further processed to alleviate the shortage of feed resources. In this study, four strains including Bacillus subtilis, Saccharomyces cerevisiae, Levilactobacillus brevis and Lactiplantibacillus plantarum were mixed at three ratios: A (B. subtilis: S. cerevisiae: L. brevis\u2009=\u20091:1:1), B (B. subtilis: S. cerevisiae: L. plantarum\u2009=\u20091:1:1), and C (B. subtilis: S. cerevisiae: L. brevis: L. plantarum\u2009=\u20091:1:1:1). 10% inoculation rate was adopted for short-term anaerobic fermentation lasting 5 days using ML, DG and their mixed substrates (ML&DG) to optimize fermentation performance and modulate the microbial community structure. The results demonstrated that exogenous microbial inoculation effectively degraded tannin (50.81%) and phytic acid (52.66%), lowered the pH value below 4.77, and increased lactic acid content to 83.43\u00a0mg/g, which was 4.57 times higher than that of the control group. Meanwhile, the mixed fermentation of mulberry leaves and distillers' grains maintained a true protein retention rate of over 99% and retained antioxidant activity, with the ABTS radical scavenging capacity of the mixed substrates reaching 114.35% relative to the initial level. Microbial analysis confirmed Lactobacillus as the dominant genus correlating with quality enhancement. This study demonstrates the efficient bio-conversion of ML and DG into high-nutrient feed via solid-state fermentation using mixed fermentation and a designed microbial consortium. This waste-to-feed strategy establishes a sustainable model for circular agriculture by transforming low-value residues into functional feed resources.",
        "42566826": "ID: 42566826\nTitle: Spatiotemporal heterogeneity drives acetic acid fermentation of traditional Chinese aromatic vinegar: Insights into microbiota dynamics and flavor formation.\nAbstract: To address the ecological implications of spatiotemporal heterogeneity on microbial assembly and flavor formation in Chinese aromatic vinegar, this study systematically revealed these dynamics during the solid-state acetic acid fermentation (AAF). Temporally, Lactobacillus, Acetobacter, and Komagataeibacter synergistically drove acid and aroma formation. In the early stage (day 1), Lactobacillus dominated, creating an acidic niche for Acetobacter. During the main fermentation stage (days 7 to 13), Acetobacter oxidized ethanol to acetic acid, while Lactobacillus accumulated lactic acid, facilitating ester production. In the late stage (day 21), increased Komagataeibacter abundance further enhanced the accumulation of acetic acid and ketones. Spatially, oxygen availability created distinct metabolic zones: the aerobic upper layer favored rapid acetic acid accumulation by the proliferation of Acetobacter and Komagataeibacter. The middle layer served as a metabolic transition zone. The anaerobic lower layer dominated by Lactobacillus accumulated lactic acid, alcohols, and esters. Bacterial community assembly shifted from stochastic to deterministic processes, with high-abundance Acetobacter and Lactobacillus (over 90%) reinforcing metabolic synergy through environmental filtering. The layer-by-layer turning process gradually reduced spatial heterogeneity, converting compartmentalized metabolism into integrated synergy, thereby ensuring balanced accumulation of aromatic compounds and maintaining acid production efficiency.",

A comprehensive insight is required to understand the precise use of Se to legumes for sustainable agriculture production and biofortification. We conducted a meta-analysis of 1644 pair-wise observations published from 2009 to 2024 and analyzed data by machine learning models (RF, XGBoost, and SVM). Effects of Se fertilizer type, concentration, exposure duration, application method, and growth medium on legume growth and physiology were evaluated. Se application at \u2264\u202f2.5\u202fmg\u202fkg-1 improved shoot dry weight, biological yield, chlorophyll content, and antioxidant enzymes (SOD, POD, CAT, and APX), while reducing oxidative stress related indicators such as H2O2. In contrast, elevated Se levels (>2.5\u202fmg\u202fkg-1) reduced yield, germination, disrupted antioxidant defenses, and increased oxidative damage. Se accumulation in legume grains exhibited an exposure-medium dependent response, with the highest accumulation observed under hydroponic conditions, followed by soil applications. Machine learning confirmed Se concentration, fertilizer type, and exposure matrix as dominant drivers of Se impact on legumes. Overall, precise Se application rate \u2264\u202f2.5\u202fmg\u202fkg-1 improves legume performance and supports sustainable legume-based agroecosystem management globally.",

Only two approved medications are available, benznidazole (BNZ) and nifurtimox, and both have suboptimal efficacy in the chronic stage of the disease and severe side effects. To overcome these limitations, we previously described the development of a lipid nanoformulation of BNZ (NLC-BNZ). Here, we extended this work to polymeric nanoparticles (EU-BNZ) and evaluated both in vivo for pharmacokinetics (PK) and efficacy. At the highest concentration tested, nanoencapsulation notably reduced BNZ cytotoxicity in CHO cells (from 50% to 100% viability). No significant differences were found in the PK profiles between the formulations and the free drug, orally administered at doses equivalent to 30 mg/kg of BNZ. In the mouse model of acute T. cruzi infection, treatment with NLC-BNZ and EU-BNZ improved survival relative to controls (empty carriers or vehicle) but was not superior to free BNZ. Consistent with the in vitro observations, mice treated with NLC showed a higher survival percentage compared to their polymeric counterparts. This finding highlights lipidic nanoparticles not merely as carriers but as potential therapeutic agents. Our findings provide a promising starting point for the exploration of lipidic compounds with potential intrinsic antiparasitic properties.",

While Akkermansia muciniphila (AKK) has shown potential in modulating neuroinflammation, its specific role and underlying mechanisms in alleviating PD-associated non-motor symptoms remain unclear. In this study, we investigated the effects of AKK intervention in 16-month-old female A53T \u03b1-synuclein (\u03b1-syn) transgenic mice. Behavioral assessments revealed that oral administration of AKK significantly ameliorated depression-like behaviors, evidenced by reduced immobility in the forced swim test and increased sucrose preference, without affecting motor function, spatial memory, or gastrointestinal motility. Mechanistically, the intervention exhibited genotype-specific effects: AKK significantly increased plasma 5-HT levels in C57 mice. This increase was associated with an enrichment of Lactobacillus taiwanensis and metabolic pathways favoring peripheral tryptophan conversion. Conversely, in A53T mice, the treatment specifically elevated hippocampal 5-HT levels without altering plasma concentrations. This central effect correlated with distinct microbial remodeling, characterized by the enrichment of butyrate/propionate-producing Lachnospiraceae and the activation of purine degradation. Collectively, these findings provide novel mechanistic insights into the therapeutic potential of AKK for managing non-motor symptoms in PD. While limited to a female cohort, our results suggest that AKK ameliorates depression-like behaviors in PD through sex-specific remodeling of the gut microbiome and serotonergic signaling.",

As functional proxies of their parent bacteria, probiotic extracellular vesicles (PEVs) have become the focus of attention in recent years because of their great potential in the treatment of IBD. This review summarizes the overview of PEVs and recent advances of PEVs on the therapeutical effect and potential mechanisms in IBD. In addition, the review discusses the possible applications and challenges of PEVs in IBD. Key scientific concepts of review: PEVs facilitate a complex molecular crosstalk that preserves intestinal homeostasis in IBD by concurrently modulating immunological response, reinforcing intestinal barrier, and stabilizing the gut microbiota. Although PEVs offer powerful innovations for the treatment of IBD, they still face challenges such as high-quality and scaled-up production, purification, safety, target specificity, and bioavailability. Consequently, future investigations will focus on establishing standard procedures of isolation, purification, and quality control while engineering PEVs for enhanced target-specific delivery in IBD treatment.",

Despite abundant links between Short-chain fatty acids (SCFAs) and intestinal health, integrative studies that connect community ecology with SCFA linked metabolism, epithelial signaling, systemic inflammation, behavior, and test causal reversibility are limited. In this study, we assessed gut microbiota and function alongside host tissues and behavior. In mice fed a high-fat diet (HFD), particularly in the 12-month-old cohort, we observed hippocampal-dependent cognitive and locomotor deficits (longer escape latency, fewer platform crossings, reduced target-quadrant time; lower distance, speed and center time), accompanied by systemic inflammation, with serum lipopolysaccharide (LPS) and cytokines (IL-6 and TNF-\u03b1) elevated and associated with adiposity. We then profiled the gut microbiota and its functions alongside host tissues and behavior, finding that HFD and age reduced \u03b1-diversity and shifted \u03b2-diversity, with a selective depletion of Muribaculaceae and depressed SCFA-linked pathways. Muribaculaceae abundance positively correlated with predicted SCFA-related pathways, while qRT-PCR of microbial fermentation genes supported concurrent functional alterations. In the colon, ELISA-measured butyrate level, SCFA receptors Ffar2, Ffar3 and tight-junction genes Tjp1 and Ocln were downregulated, with ZO-1 and occludin mislocalization, while serum LPS and inflammatory cytokines increased and associated with adiposity. Notably, an intervention arm showed that sodium butyrate supplementation attenuated cytokinemia, restored Ffar2, Ffar3 and tight-junction expression, improved ZO-1 and occludin integrity, and rescued behavioral performance. Collectively, these findings support an association between Muribaculaceae depletion, reduced SCFA-related functional signatures, impaired barrier associated markers, systemic inflammation, and behavioral deficits under HFD and age-associated conditions. In an intervention setting, butyrate supplementation partially ameliorated inflammatory and barrier-related readouts and improved behavioral performance.",

However, the mechanistic basis linking dietary MP exposure to gut dysbiosis and intestinal dysfunction remains poorly resolved, limiting robust human health risk assessment. This review critically synthesizes current evidence on foodborne MPs, dietary exposure, and the physicochemical determinants of gastrointestinal fate, bioavailability, and toxicity. We examine the molecular and microbiome-mediated mechanisms linking MPs exposure to intestinal dysbiosis, barrier dysfunction, oxidative stress, immune activation, and metabolic reprogramming. Particular attention is given to the role of MPs as vectors for co-contaminants, which can amplify toxicity through synergistic interactions and reshape host-microbiome responses. We highlight advances in dynamic colon simulation and integrated multi-omics that unravels the mechanism underlying MP-induced intestinal toxicity. Current evidence indicates that gut microbiome dysregulation is a key mechanism driving foodborne MP-induced intestinal dysfunction and systemic toxicity. This review integrates multidisciplinary evidence to identify critical knowledge gaps and guide future research on the mechanisms, exposure, and health risks of foodborne microplastics.",

However, limited evidence exists on how different formulations with enhanced bioavailability compare in clinical outcomes with one another, even if there is extensive research on vitamin D tablets. Post-menopausal women's bone mineral density (BMD), bone turnover markers, and fracture risk over a 24-month period were evaluated using regular cholecalciferol, micronized cholecalciferol, and liposomal vitamin D3 combined with calcium supplements. Using age and baseline 25-hydroxyvitamin D [25(OH)D] levels, 612 post-menopausal women (ages 50-75 years) with T-scores ranging from -1.5 to -2.5 on dual-energy X-ray absorptiometry (DXA) were randomly assigned to one of four groups: regular cholecalciferol (1200 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), micronized cholecalciferol (1200 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), liposomal vitamin D3 (800 IU/day + 1000\u2009mg calcium, n\u2009=\u2009153), or placebo (n\u2009=\u2009153). Other results were changes in femoral neck, lumbar spine, total hip bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), C-terminal telopeptide of type I collagen (CTX), serum 25(OH)D levels, and incidence of new fragility fractures. Mean serum 25(OH)D levels were substantially higher (p\u2009=\u20090.003) in the liposomal group (38.2\u2009\u00b1\u20097.5\u2009ng/mL) than those in the control cholecalciferol group (28.5\u2009\u00b1\u20096.8\u2009ng/mL). The liposomal vitamin D3 group exhibited somewhat higher femoral neck BMD (2.8% \u00b1 1.2%; p\u2009=\u20090.012) and lumbar spine BMD (2.8% \u00b1 1.2%; p\u2009=\u20090.008) enhancement than did the placebo group (1.1% \u00b1 0.9%). The liposomal form showed the highest ratio (2.4\u2009\u00b1\u20090.6 versus 1.8\u2009\u00b1\u20090.5 placebo; p\u2009=\u20090.001); hence, BSAP/CTX ratios were significantly better in all the active treatment groups. Eight patients (5.2%) in the placebo group had fresh fragility fractures; two (1.3%), three (2.0%), and one (0.7%) in the conventional, micronized, and liposomal groups, respectively; \u03c7\u00b2 = 7.42; p\u2009=\u20090.059. Greater success in raising bone mineral density and lowering indicators of bone turnover with recent bioavailability-enhanced vitamin D3 formulas was observed in post-menopausal women, especially those on liposomal delivery systems. These results suggest that public health guidelines and clinical practice have to take into account a rather important element impacting the efficacy of vitamin D supplements: formulation technology.

Flavonoids, plant-derived polyphenols encompassing seven structural subclasses, exhibit considerable preclinical promise through multi-target mechanisms but face translational barriers owing to poor oral bioavailability and insufficient clinical validation. This review systematically evaluates 33 structurally characterized single flavonoids for their therapeutic mechanisms, pharmacological targets, and translational prospects in MASLD, integrating evidence from cellular models, diverse rodent models, and available clinical trials. A tiered evidence classification (Levels A-C) was applied based on clinical data availability, multi-model validation, mechanistic depth, and study design rigor. Mechanistically, flavonoids restore hepatic lipid homeostasis by concurrently inhibiting SREBP-1c-mediated de novo lipogenesis and promoting PPAR\u03b1-driven fatty acid \u03b2-oxidation via AMPK activation; ameliorate insulin resistance through IRS-1/PI3K/Akt signaling; attenuate hepatic inflammation by suppressing NF-\u03baB/NLRP3 inflammasome cascades; reinforce antioxidant defenses via Nrf2/ARE-mediated induction of HO-1, SOD, and GPX4 with concomitant ferroptosis inhibition; enhance autophagic-lysosomal lipid clearance through TFEB nuclear translocation and Sirt1-dependent lipophagy; and remodel gut microbiota composition to fortify intestinal barrier integrity. Genistein, dihydromyricetin, quercetin, and kaempferol exemplify polypharmacological engagement across multiple pathways. Despite robust mechanistic evidence, oral bioavailability remains limited to 1%-5% owing to poor aqueous solubility, extensive phase II conjugation, and food-matrix interactions. Emerging strategies-carbamate prodrugs, nanoliposomes, biomimetic nanoemulsions, and colon-targeted nanoparticles-demonstrate feasibility in surmounting these barriers. Clinical evidence reveals compound-specific efficacy profiles: hesperidin reduces steatosis and transaminases; genistein improves insulin sensitivity; naringenin ameliorates lipid profiles without altering fibrosis markers. Critical appraisal identifies persistent limitations including small sample sizes, predominant reliance on male animals, short intervention durations, and absence of biopsy-confirmed endpoints. Future research must prioritize rigorous multicenter randomized controlled trials with optimized formulations, comparative efficacy studies, systematic safety evaluations, and multi-omics integration to bridge the translational gap toward evidence-based flavonoid therapeutics for MASLD.",

A total of 135 wheat samples representing five geographic regions and nine cultivars were subjected to sensory evaluation, physicochemical analysis, and 16S rRNA gene and ITS amplicon sequencing. Microbial community composition, predicted functional potential, and their associations with wheat quality traits were analyzed using PICRUSt2, Mantel tests, and correlation analyses. Sensory evaluation indicated that the cultivation environment had a greater impact on Daqu quality than wheat cultivar, with wheat from the Dayi region and the MM916 cultivar exhibiting the most favorable characteristics. Sequencing identified 1,732 bacterial and 484 fungal amplicon sequence variants (ASVs), revealing significant geographic and varietal differences in microbial communities, while core taxa dominated by Pseudomonadota and Basidiomycota were consistently detected across all samples. Functional prediction suggested that microbial communities were primarily enriched in metabolic pathways, particularly carbohydrate metabolism, energy metabolism, and cofactor and vitamin metabolism. Spatial variation was observed in starch and sucrose metabolism, acetoin biosynthesis, and enzymes such as \u03b2-glucosidase and alcohol dehydrogenase. Wheat quality traits, especially protein, starch, and wet gluten content, were significantly associated with microbial composition and predicted functions. Thirty-two genera, including Sphingomonas, Pedobacter, and Martelella, showed strong correlations with these quality traits. Geographic origin and wheat cultivar jointly shape the microbial communities and functional potential of brewing wheat, providing pre-existing microbial resources that may influence early Daqu fermentation and flavor formation. These findings offer a microbiome-based framework for evaluating and selecting high-quality wheat for Baijiu production.",

Marine-derived bioactive compounds from Mexican Pacific Sargassum species have emerged as promising nutraceutical candidates due to their antioxidant, anti-inflammatory, and cytoprotective properties. This narrative review critically examines the nutritional composition and pharmacologically relevant bioactive constituents of Mexican Pacific Sargassum, with emphasis on fucoxanthin, fucoidans, phlorotannins, and polyunsaturated fatty acids. Particular attention is given to their molecular mechanisms of action in AMD-related pathways, including modulation of oxidative stress, Nrf2/HO-1 signaling, NF-\u03baB-mediated inflammation, VEGF-associated angiogenesis, mitochondrial dysfunction, and apoptosis in retinal cells. Current evidence from preclinical retinal models suggests that these compounds may exert protective effects against AMD progression through multipronged regulation of redox and inflammatory pathways. Additionally, major translational challenges related to bioavailability, extraction standardization, safety, and the absence of AMD-specific clinical trials are critically discussed. Overall, Mexican Pacific Sargassum represents a promising yet underexplored source of marine bioactives with potential applications in the development of nutraceutical strategies targeting retinal degeneration and AMD.",

Inspired by the metabolic division of labor in gut ecosystems, we proposed and validated a metabolism-guided strategy for an experimental membrane bioreactor (MBR-E) with a prefermentation unit that couples upstream fermentation with downstream denitrification to restructure carbon flux toward more bioavailable electron donors for nitrogen removal. Long-term operation showed that MBR-E achieved significantly lower effluent total nitrogen (7.9 \u00b1 2.4 mg/L) compared with the control MBR system (MBR-C, 12.3 \u00b1 3.5 mg/L), which was attributed to its elevated specific denitrification rate. Influent organics were efficiently converted into volatile fatty acids (VFAs) via fermentation and shortening hydraulic retention time from 0.67 h to 0.5 h shifted VFA composition from propionate/butyrate dominance to acetate enrichment. Further, 16S rRNA gene sequencing demonstrated that functional denitrifiers and nitrifiers were selectively enriched in MBR-E. Co-occurrence network analysis revealed strengthened cooperative interactions and tighter functional coupling between carbon degradation and nitrogen removal in MBR-E. Overall, this study demonstrates that fermentation-driven carbon reprogramming can effectively regulate downstream respiratory pathways and reshape the microbial community structure, providing a novel approach for efficient nitrogen removal from low-carbon/nitrogen wastewater.",

Growth of GR536 in an iron-restricted liquid medium resulted in apparent lysis during the early exponential growth phase. This effect was exacerbated in cells transformed with pBAD30, a commonly used arabinose-inducible expression vector. Whole-genome sequencing confirmed the expected gene disruptions (entC, feoABC, mntH, zupT::cat and fecABCDE::kan). However, comparison to E. coli W3110 identified the presence of the \u03d580 prophage (46.16 kbp) and cryptic prophage CPZ-55 (6.763 kbp), as well as the absence of cryptic prophage e14 (15.193 kbp). We also identified 9 IS-element deletions, 3 IS-element insertions, 7 other deletions or insertions and 74 candidate individual nucleotide changes. The growth defect in GR536 correlated with lysis due to the production of \u03d580 virions as determined by the inability of isolated phage to infect an E. coli strain lacking the phage receptor (\u2206fhuA) and the BamHI digestion pattern of the purified phage DNA. We further determined that the \u03d580-dependent lysis in GR536 is exacerbated by the presence of the chloramphenicol- and kanamycin-resistance markers introduced during construction of GR536 and the pBAD30 plasmid multiple cloning site. Removal of the markers (E. coli GR536*) and disruption of the pBAD30 multiple cloning site generated a strain that showed a 104-fold reduction in \u03d580 production. Furthermore, construction of a W3110 lysogen containing the \u03d580 prophage and comparison with GR536* grown under the same conditions showed a ~104-fold higher level of phage production by the parent strain, indicating that phage-dependent lysis was not increased by the deletion of the metal-uptake genes and thus independent of iron availability. These observations clarify growth conditions that limit the effects of \u03d580-dependent lysis when using GR536 to identify metal-uptake genes by complementation, specifically, removal of the antibiotic resistance markers and the avoidance of using intact pBAD30 as a negative control.",

Despite advances in advanced oxidation processes, there remains a lack of generalizable methods that reliably modulate 1O2 selectivity. Here, we propose a descriptor-assisted coordination modulation strategy, in which machine-learning analysis identifies the d-band center as an important electronic descriptor associated with 1O2 selectivity. Through N-coordination modulation, the CoN5 catalyst exhibited near-complete 1O2 selectivity among the quantified reactive oxygen species (ROS) with a steady-state concentration of 394 \u00b5M, outperforming recent reports. As an internal-circulation pre-oxidation module, the CoN5/peroxymonosulfate (CoN5/PMS) system continuously raised wastewater biochemical oxygen demand/chemical oxygen demand (BOD/COD) to above 0.5 over 192\u00a0h, increased bioavailable dissolved organic matter (DOM), and showed high microbiome compatibility, evidenced by reduced Vibrio fischeri inhibition and microbial diversity ordination clustering near the background with greater shared-taxa overlap. This system also enabled selective thioanisole oxidation, achieving 90.6% conversion and 99.5% selectivity, with green synthesis potential demonstrated in a three-chamber continuous single-pass reactor. These results establish a generalizable coordination principle for steering ROS pathways and provide a deployable, low-ecological-risk route for both mixed wastewater treatment and green chemical synthesis.",
        "42570476": "ID: 42570476\nTitle: Comprehensive characterization of walnut oil processing by-products: biochemical composition, bioactive properties, and polyphenol in vitro bioaccessibility and bioavailability.\nAbstract: Underutilized by-products from the walnut-oil industry, namely walnut oilcake (WOC) and walnut oil dregs (WOD), were evaluated for their nutritional composition, phenolic compound profile and digestive behaviour, as well as bioactive properties (antioxidant, antimicrobial, anti-inflammatory, cytotoxic and prebiotic activities). WOC was rich in protein (38.1\u00a0g/100\u00a0g) and dietary fiber (32.6\u00a0g/100\u00a0g), while WOD presented high fat (46.8\u00a0g/100\u00a0g) and carbohydrate content (20.9\u00a0g/100\u00a0g). Glansreginin A was the predominant phenolic compound in both matrices. Following in vitro digestion using the INFOGEST protocol, higher overall polyphenol bioaccessibility was noticed in WOD (78%) compared to WOC (15%). Bioaccessible fractions exhibited higher antioxidant activity than the undigested samples. Glansreginin A was detected only on the cellular apical compartment suggesting the absence of transport across Caco-2 cells. After in vitro digestion, the non-bioaccessible fractions enhanced the growth of Lactobacillus and Bifidobacterium strains, in some cases surpassing fructooligosaccharides, a standard prebiotic. These findings support the valorisation of walnut by-products as functional ingredients, also contributing to sustainable food systems.",
        "42570481": "ID: 42570481\nTitle: Lutein-loaded Pickering high internal phase emulsions stabilized by protein-polyphenol-polysaccharide self-assembled particles: Interfacial behavior, in vitro/in vivo stability and release.\nAbstract: This study aimed to encapsulate lutein in high internal phase emulsions (HIPEs) stabilized by quinoa protein isolate (QPI), tannic acid (TA), and high-methoxy pectin (HMP) particles at varying concentrations to address its low delivery efficiency and bioavailability. High concentrations (3%-4%) of QPI-TA-HMP particles demonstrated strong interfacial adsorption, forming thick viscoelastic films around oil droplets. These interfacial properties imparted controllable rheological behaviors, textural characteristics, and stable 3D-printing scaffolds to the lutein-loaded HIPEs, achieving an encapsulation efficiency of 81.65\u00a0\u00b1\u00a02.36%. In vitro tests indicated that HIPEs enhanced lutein's resistance to storage, heat, and UV exposure while facilitating sustained intestinal release, resulting in a lutein bioaccessibility of 43.73\u00a0\u00b1\u00a01.44%. In vivo experiments further demonstrated that the HIPEs delivery system maintained high lutein concentrations in the small intestine, cecum, and colon, thereby significantly enhancing lutein accumulation in systemic circulation. These findings provide new insights into enhancing lutein's stability, delivery performance, and bioavailability.",
        "42570615": "ID: 42570615\nTitle: Taxifolin ameliorates radiation-induced colitis via the gut microbiota-BAs-FXR/NLRP3 axis.\nAbstract: Radiation-induced colitis (RC) poses a substantial clinical challenge with limited therapeutic options. Taxifolin (TAX), a natural flavonoid, exhibits potential anti-inflammatory properties; however, its clinical application is hindered by poor oral bioavailability and an unclear mechanism of action in the context of radiation injury. This study aims to investigate the therapeutic potential and underlying mechanisms of the flavonoid monomer TAX in the context of RC, with a particular focus on the gut microbiota-BAs-FXR/NLRP3 axis. We employed a 13 Gy total abdominal irradiation (TAI) mouse model and HIEC-6 cells. Multi-omics approaches, including 16S rRNA sequencing and untargeted metabolomics, were used to map microbiota and metabolic profiles. Crucially, to establish causality, fecal microbiota transplantation (FMT) was performed to assess the microbiota's mediating role, and the specific FXR antagonist DY268 was utilized to verify the dependency on FXR signaling. Molecular interactions were confirmed via molecular docking, drug affinity responsive target stability (DARTS), and co-immunoprecipitation (Co-IP) assays. TAX significantly mitigated RC, characterized by preserved intestinal barrier integrity and reduced inflammatory cytokine production. It reshaped microbial homeostasis, specifically enriching bile acid (BA)-metabolizing genera (such as Lachnoclostridium) and promoting the accumulation of specific FXR-activating BAs, including glycocholic acid (GCA), taurochenodeoxycholic acid (TCDCA), and ursodeoxycholic acid (UDCA). FMT from TAX-treated donors successfully recapitulated the radioprotective phenotype in recipient mice, confirming the causal role of the gut microbiota. Mechanistically, both TAX and the enriched BAs directly bound to the farnesoid X receptor (FXR), inducing conformational changes that enhanced its physical interaction with NLRP3, thereby inhibiting inflammasome assembly and downstream signaling. Importantly, pharmacological blockade of FXR by DY268 abolished the protective effects of TAX, confirming that FXR activation is indispensable for its therapeutic action. TAX mitigates RC not merely as an antioxidant, but as a microecological modulator. Importantly, TAX acts as a natural modulator of the \"gut microbiota-BAs-FXR/NLRP3\" signaling axis for RC therapy. TAX-induced microbiota changes promote the production of specific bile acids that amplify intestinal FXR signaling to suppress inflammation. This study provides a robust mechanistic basis for using TAX as an orally active radioprotectant targeting the gut-liver axis.",
        "42570864": "ID: 42570864\nTitle: Genome-scale modeling of the influence of microbiota-derived butyrate on the regulation of human metabolism by the histone deacetylase SIRT1.\nAbstract: Genome-scale metabolic models predict metabolic flux distributions but typically lack explicit transcriptional regulation, limiting their ability to simulate graded effects of epigenetic modulators such as Sirtuin1. To develop and validate a continuous regulatory-metabolic framework integrating Sirtuin T1-dependent transcriptional control into human genome-scale metabolism and to quantify the metabolic impact of microbiome-derived butyrate in intestinal epithelial cells. A curated Sirtuin1-centered regulatory network comprising 8 transcriptional regulators, 487 metabolic genes, and 2,296 reactions (\u223c22% of Recon3D) was integrated into the Recon3D reconstruction to generate iSirtuin1_HumanMet. Continuous regulatory logic was implemented within steady-state regulatory flux balance analysis. Tissue-specific models were derived from genotype-tissue expression transcriptomic data using FASTCORE. Human Caco-2 intestinal epithelial cells were treated with 0-9 mM sodium butyrate for 72 h. Sirtuin1 protein expression was quantified by Western blot and modeled using an inverse exponential regression (R2 = 0.669). Predicted maximal intracellular production capacities were compared with independent metabolomics data using Spearman correlation. Simulated Sirtuin1 activation (0.0-1.0) modulated 2,296 reactions, with 34.2% of upregulated reactions belonging to fatty acid oxidation. Increasing Sirtuin1 promoted gluconeogenesis and lipid utilization while repressing glycolysis and nucleotide interconversion. Tissue-specific simulations across 54 tissues revealed distinct clustering of metabolic responses. Incorporation of experimentally derived butyrate-Sirtuin1 inhibition resulted in concordant monotonic trends between predicted and measured intracellular metabolites for 11 of 13 metabolites (85%), with Spearman \u03c1 ranging from -0.64 to 0.94 (median \u03c1 \u2248 0.74). Integration of microbiome-predicted butyrate fluxes showed strong host metabolic associations, including correlations up to \u03c1 = -0.92 (p = 8.77 \u00d7 10-22). In Caco-2 intestinal epithelial cells and tissue-specific human metabolic models, continuous integration of Sirtuin1 regulation enables quantitative simulation of graded transcriptional control and microbiome-derived metabolic modulation, providing a systems-level framework to study diet-microbiome-host metabolic interactions."
