This study aimed to isolate an EPS-producing bacterium from naturally fermented cucumber and to perform a preliminary physicochemical and spectroscopic characterization of the produced polymer. An EPS-producing bacterial isolate was recovered and identified as Bacillus tequilensis, a member of the Bacillus subtilis species complex, based on 16\u00a0S rRNA gene sequence analysis. The extracellular polysaccharide was partially purified and analyzed using FTIR and \u00b9H NMR spectroscopy, revealing structural features consistent with a glucan-type EPS. Rheological analysis demonstrated a concentration-dependent increase in viscosity, confirming the macromolecular nature of the polymer in aqueous systems. Sucrose-hydrolyzing activity was detected under optimized conditions, indicating active carbohydrate metabolism associated with EPS production. In vitro cytocompatibility assessment using Vero and WI-38 cell lines showed high cell viability at low to moderate concentrations, with a dose-dependent reduction observed at higher levels. Overall, this study reports the isolation of an EPS-producing Bacillus tequilensis strain from Egyptian fermented cucumber and provides preliminary insights into the properties of its glucan-type exopolysaccharide, highlighting fermented vegetable microbiota as a potential source of functional biopolymers."

"abstract_text": "ID: 42212401\nTitle: Texture Engineering of Nondairy Yogurt Alternatives: Ingredient Selection, Processing Strategies, and the Role of In Situ Dextrans.\nAbstract: A global shift from diets rich in animal-based products toward plant-based diets has been widely promoted as a key strategy for creating more sustainable food systems. However, the adoption of plant-based alternatives depends on multiple factors, including consumer preferences, sensory quality, product affordability, and availability, in addition to sustainability and ethical considerations. Although nondairy yogurt alternatives may offer environmental advantages over conventional dairy products, their broader adoption is often constrained by textural limitations, which remain a major barrier to consumer acceptance. Addressing texture deficiencies requires strategic ingredient selection and optimized processing techniques. While existing literature focuses primarily on plant-based systems, alternative protein sources such as fungal proteins remain underexplored, with few studies evaluating fungal protein-based yogurt analogues. This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy. Compared with many heteropolysaccharides often produced at relatively low yields by yogurt starters, dextran, a homopolysaccharide, can be synthesized at higher levels by certain lactic acid bacteria (LAB) and contributes to enhanced viscosity and gel formation in plant-based matrices. We discuss the mechanisms underlying these effects, including dextran-protein interactions and water-binding capacity, as well as their relevance to clean-label and functional food trends. Key research priorities include identifying food-grade, high-yield dextran-producing LAB strains, assessing their safety and allergenicity, and investigating the digestive fate and health effects of in situ-produced dextrans. Overall, in situ dextran production represents a promising strategy for improving the texture and consumer acceptance of nondairy yogurt alternatives."

"abstract_text": "ID: 42280098\nTitle: Striatal Metabolomic Profiling Links Brazilian Green Propolis to Suberic Acid Modulation and Nigrostriatal Neuroprotection in a Rat Model of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is characterized by progressive nigrostriatal degeneration and striatal dysfunction, yet its metabolic remodeling remains incompletely defined. Here, untargeted GC-MS metabolomics was used to investigate the effects of standardized Brazilian green propolis on the striatal metabolic profile in the 6-hydroxydopamine (6-OHDA) rat model. Discriminant metabolites, including suberic acid, gluconic acid, heptadecane, and tartaric acid, distinguished experimental groups, capturing key features of the metabolic response to dopaminergic injury and treatment. Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways. Propolis treatment attenuated the elevation of suberic acid, accompanied by a reduction in gluconic acid levels, suggesting a metabolic profile linked to pathways involved in redox balance and glucose handling. Given previous reports identifying heptadecane as a hydrocarbon constituent of volatile propolis fractions, complementary GC-Q-TOF analyses demonstrated that heptadecane was absent from the administered extract, despite its consistent association with propolis-treated groups. Metabolic changes were accompanied by attenuation of nigrostriatal dopaminergic neurodegeneration and improved motor performance. Together, these findings delineate a striatal metabolic signature associated with Brazilian green propolis and identify suberic acid as a key metabolite linked to neuroprotection in experimental Parkinsonism."

This study examined the impact of three probiotic combinations-Y1 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus rhamnosus), Y2 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus paracasei) and Y3 (Lactobacillus plantarum and Bifidobacterium sps.)- on microbial dynamics and metabolite formation in lupin-oat yoghurt analogues, using unfermented milk analogues as a control. Samples were assessed during fermentation and throughout 28 days of refrigerated storage (4 \u00b0C) using microbial enumeration, 16S rRNA sequencing, acidification profiling, and mass spectroscopy-based metabolomics. Fermentation increased volatile compounds, from 23 in the control to 28 (Y1), 41 (Y2) and 54 (Y3). Probiotic combination Y3 exhibited the most complex and stable aroma profile, enriched in pleasant volatiles such as butanoic acid, phenylacetaldehyde, and butyl esters which effectively masked off-flavours like hexanal and heptanal. Microbiota analysis revealed stable formulation-specific communities, with- Streptococcus dominating in yoghurt analogues Y1 and Y2, and Bifidobacterium prevailing in yoghurt analogues Y3. KEGG-based functional prediction linked these transformations to microbial enzymatic activities within metabolic pathways. Notably, Bifidobacterium dominance in Y3 facilitated enhanced ester biosynthesis and conversion of aldehydes to acids, highlighting the \"bifid shunt\" as a key contributor to flavour enhancement. This integrated multi-omics approach highlights the critical role of targeted probiotic selection in modulating fermentation biochemistry, microbial ecology, and sensory attributes in plant-based lupin-oat yoghurt analogues. Notably, Bifidobacterium-driven fermentation in Y3 offers a promising strategy for improving the flavour profile and consumer acceptance of lupin-oat yoghurt analogues."

The optimal preparation process of HPSCH was investigated by using schisandrin content and total extractive yield as indices. After one week of adaptive feeding, C57BL/6 mice were assigned to a normal control group, while the remaining mice were fed an HFD for eight weeks to establish the NAFLD mouse model. After being successfully modeled, the mice were divided into a blank control group, blank administration group, simple model group, fenofibrate group, SCH group, and HPSCH group. All groups were administered by intragastric administration for four weeks. Body weight changes of mice were recorded, and liver indices were calculated. The levels of blood lipid and liver function index in the serum of mice were measured. Hepatic histopathological changes were observed by using hematoxylin-eosin(HE) staining and oil red O staining. Mice's feces were collected, and the 16S rDNA high-throughput sequencing method was employed to analyze changes in the gut microbiota of mice. Untargeted lipidomic analysis of the liver was conducted by using liquid chromatography-mass spectrometry(LC-MS), and principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were adopted to screen and identify differential metabolites. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to perform relevant pathway analysis. Integrated analyses of gut microbiota and differential metabolites were performed to compare the similarities and differences in efficacy of HPSCH and SCH. The results show that both the HPSCH group and SCH group exert similar effects on biochemical indices in serum and hepatic pathological changes, lipid metabolism can be regulated, and liver injury in NAFLD mice can be improved. The two groups show similar changes in microbial abundance, trending toward the blank control group and maintaining intestinal homeostasis. Compared with those of the simple model group, the differential metabolites and metabolic pathways of both the HPSCH group and SCH group show similarity, and the differential metabolites are mainly triglycerides, diglycerides, phosphatidylcholines, phosphatidylglycerols, and so on. Metabolic pathways include glycerophospholipid metabolism, choline metabolism, retrograde endocannabinoid signaling, thermogenic lipolysis, and so on. This indicates that HPSCH and SCH share common advantages in improving hepatic function in mice and achieve comparable effects. HPSCH can improve blood lipid and liver function indices in NAFLD mice, attaining the therapeutic effect through the regulation of gut microbiota and lipid metabolism. Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application. Moreover, the application of HPSCH may contribute to the conservation of medicinal resources."

An oxidative injury model in MC3T3-E1 cells was established with 200 \u03bcmol\u00b7L~(-1) H_2O_2. The experiment was conducted with four groups: normal, model, psoralen, and inhibitor groups. Cell viability and proliferation were assessed by the CCK-8 assay and EdU incorporation assay, respectively. Apoptosis was analyzed by Annexin V-FITC/PI double-staining flow cytometry. Mitochondrial membrane potential was evaluated with the JC-1 probe, and reactive oxygen species(ROS) levels were measured by the DCFH-DA probe. Early osteogenic differentiation markers and late mineralized nodule formation were observed by alkaline phosphatase(ALP) staining and alizarin S staining, respectively. Transmission electron microscopy was employed to examine mitochondrial ultrastructure changes. Immunofluorescence staining and Western blot were employed to determine the expression levels of PINK1, Parkin, p62, Runt-related transcription factor 2(Runx2), and Osterix. Molecular docking and 100 ns molecular dynamics simulations were conducted to validate the binding mode and stability of psoralen with PINK1. The results showed that psoralen ameliorated H_2O_2-induced cell damage in a concentration-dependent manner, with the optimal concentration being 80 \u03bcmol\u00b7L~(-1). Psoralen significantly promoted cell proliferation, upregulated the expression of Runx2, Osterix, PINK1, and Parkin, enhanced mitochondrial membrane potential, increased mitophagy levels and osteogenic differentiation capacity, and enlarged mineralized nodule area. Simultaneously, it inhibited apoptosis, reduced intracellular ROS content, and downregulated the expression of autophagy substrate p62. Molecular docking results showed that the binding energy between psoralen and PINK1 was-7.024 kcal\u00b7mol~(-1), and 100 ns molecular dynamics simulations further confirmed the structural stability of the formed complex with persistent hydrogen bond interactions. In conclusion, psoralen directly targets and activates the PINK1/Parkin pathway to mediate mitophagy, clear damaged mitochondria, improve the oxidative stress microenvironment, promote the expression of osteogenic marker proteins and mineralization, thereby enhancing osteogenic differentiation of MC3T3-E1 cells, providing a new target and candidate drug for the prevention and treatment of osteoporosis."

Ubiquitination modification is implicated in the pathogenesis of cardiovascular diseases through diverse biological processes. However, the role of TRIM9, an E3 ubiquitin ligase, in AD remains unexplored. In this study, the expression profiles of TRIM9 and SMAD4 were analyzed using clinical samples, as well as Angiotensin II (Ang II)-induced mouse and human aortic endothelial cell (HAEC) models. Endothelial barrier function in AD was assessed through CCK-8 assays, vascular permeability measurements, immunofluorescence staining, hematoxylin-eosin and Verhoeff's van Gieson staining, and Western blot analysis. The underlying molecular mechanisms were elucidated using quantitative real-time PCR, immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and enzyme-linked immunosorbent assay (ELISA). TRIM9 was markedly overexpressed, whereas SMAD4 was significantly downregulated in AD. Knockdown of TRIM9 attenuated endothelial permeability, preserved the endothelial barrier integrity, and inhibited pyroptosis both in vivo and in vitro. Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression. Collectively, these findings demonstrate that elevated TRIM9 expression aggravates AD progression through SMAD4 destabilization, offering novel therapeutic insights for AD management."

Stilbamidine (SDC), a compound identified in Malaysian Kelulut honey (KH), has been reported to exhibit favourable binding affinity towards ACE2. This study aims to determine the effects of KH and SDC on the binding of spike protein to the ACE2 receptor, as well as to assess their modulatory potential on ACE2 gene and protein expression in lung and kidney cells.

"abstract_text": "ID: 42311683\nTitle: Gut microbiota modulation in the prevention and treatment of heat stroke.\nAbstract: In recent years, heat stroke (HS) have been reported with increasing frequency, and this trend is hard to separate from broader environmental changes, including climate change, recurrent extreme heat events, and air pollution. When people are exposed to high-temperature environments for a prolonged period, especially during intense physical activity, the condition may progress to HS. HS is an acute and potentially fatal disorder that can deteriorate rapidly if not treated in time. The intestine appears to be particularly vulnerable during HS. HS can disrupt intestinal tight junctions and weaken the barrier function of the gut, leading to what is commonly described as a \"leaky gut.\" Once this barrier is compromised, microbial products such as lipopolysaccharides can enter the bloodstream. These molecules may then activate immune cells, promote excessive cytokine release, and eventually drive a systemic inflammatory response. In severe cases, this inflammatory process can develop into systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Current evidence increasingly suggests that intestinal injury is not simply a secondary result of HS. Rather, it may serve as an important early event in the development and progression of the disease. Still, it should be noted that much of the available evidence comes from preclinical studies, and strong clinical confirmation is still limited. Probiotics have attracted attention because they may help reduce the occurrence and severity of HS by maintaining gut microbiota balance and regulating intestinal immune responses. However, since most supporting data are still derived from animal experiments, their protective effects in humans need to be interpreted carefully. Another point worth emphasizing is that the gut is not working alone. Through gut-organ communication networks, the intestinal microbiota can interact with distant organs, including the liver, lungs, and brain. These gut-liver, gut-lung, and gut-brain axes may help explain how HS leads to injury beyond the intestine itself. In this review, we summarize current findings on how modulation of the gut microbiota may improve intestinal thermotolerance and strengthen barrier function, with the aim of providing useful insights for the prevention and treatment of HS in clinical practice."

This study evaluated the effects of Lactobacillus plantarum 1582-fermented red onion bulb extract (LFRO), supplied through drinking water, on growth performance, cecal microbiota, and excreta gas emissions in heat-stressed yellow-feather chickens. A total of 300 one-day-old male Rilai chicks were assigned to four treatments in a completely randomized design with five replicate pens of 15 birds each: unsupplemented control or LFRO at 25, 50, or 100\u00a0mg/L in drinking water. Birds were reared for 70 days under natural chronic tropical heat stress, with the temperature-humidity index predominantly within the severe-to-very severe range (28.9-31.1). Supplementation with 100\u00a0mg/L LFRO increased final body weight and body weight gain, reduced feed intake, and improved feed conversion ratio over the whole trial. The European Production Efficiency Index and Broiler Performance Efficiency Factor were also highest in the 100\u00a0mg/L group. Cecal 16\u00a0S rRNA sequencing showed no major changes in alpha- or beta-diversity, but several selected bacterial genera were modulated. LFRO at 50 and 100\u00a0mg/L reduced ammonia emission from excreta, whereas the other measured gases were not affected.

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

Rhubarb (RR) is widely applied to treat IS in the clinic. However, its underlying pharmacological mechanisms remain incompletely elucidated. To dissect the mechanism and pharmacological basis of RR's ability to ameliorate IS from the side of modulating tryptophan-kynurenine (TRP-KYN) metabolism and neuroinflammation. An embolic middle cerebral artery occlusion (MCAO) model was employed in rats to simulate human IS. Neurological deficit scores, hematoxylin-eosin, 2,3,5-triphenyltetrazolium chloride, alcian blue-periodic acid-Schiff staining, Western blotting, targeted metabolomics, immunofluorescence, and enzyme-linked immunosorbent assay were utilized to evaluate the efficacy of RR against cerebral ischemic injury, gut permeability, TRP-KYN metabolism levels, and neuroinflammation. Surface plasmon resonance and cell-based assays were further utilized to screen and validate potential bioactive ingredients of RR for the treatment of IS. In addition to mitigating cerebral ischemic damage, RR treatment substantially restored intestinal barrier function in IS rats by reducing leaky gut biomarkers, ameliorating histopathological alterations, and upregulating colonic tight junction proteins. Moreover, RR modulated TRP-KYN metabolism, concomitant with regulated expression and enzymatic activity of indoleamine 2,3-dioxygenase 1 (IDO-1) and the triggering receptor expressed on myeloid cells-1 (TREM-1) levels in both colon tissue and serum. Within the central nervous system, RR attenuated neuroinflammation triggered by MCAO through orchestrating microglial polarization and cytokine levels, accompanied by suppression of the TREM-1-mediated inflammatory signaling cascade. Chrysophanol 8-O-\u03b2-d-glucoside, rutinum, lindleyin, and (-)-catechin gallate from RR were identified as potential IDO-1 inhibitors, while rhein, lindleyin, methyl gallate, and chrysophanol 8-O-\u03b2-d-glucoside were identified as potential TREM-1 inhibitors, capable of attenuating the overexpression of IDO-1 and TREM-1 or TREM-1 and NOD-like receptor protein 3 (NLRP3). This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation. These effects are attributed to its bioactive components, including rutinum, chrysophanol 8-O-\u03b2-d-glucoside, lindleyin, (-)-catechin gallate, rhein, and methyl gallate."

Although irritable bowel syndrome (IBS) is considered a disorder of gut-brain interaction, the role of UA in IBS remains unclear. An experimental rat model of IBS was induced using laser-induced shock waves (LISW) applied to the head. Hyperuricemia (HUA) was induced by intraperitoneal administration of inosine monophosphate and potassium oxonate. Visceral hypersensitivity was assessed by colorectal distension. Ileal mucosal permeability was measured using the Evans blue method. CRFR1 mRNA expression in the rectum, IL-10 and TGF-\u03b21 expression in the ileum, and IL-1\u03b1, IL-1\u03b2, and TNF expression in the medial prefrontal cortex (mPFC) and paraventricular nucleus (PVN) were quantified by qRT-PCR. Vagal involvement was assessed using subdiaphragmatic vagotomy or atropine treatment. LISW increased visceral hypersensitivity, ileal mucosal permeability, and rectal CRFR1 expression and reduced IL-10 expression in the ileum. HUA significantly ameliorated these changes. HUA was also associated with reduced IL-1\u03b2 expression in the mPFC and reduced IL-1\u03b1 and IL-1\u03b2 expression in the PVN in LISW-treated animals. Importantly, the ameliorative effects of HUA on visceral hypersensitivity were abolished by vagotomy or atropine treatment. Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain. The loss of HUA-induced suppression of visceral hypersensitivity after vagotomy or atropine treatment suggests the possible involvement of vagal and cholinergic brain-gut communication. Irritable bowel syndrome (IBS) is a common disorder in which people experience abdominal pain and bowel problems, often worsened by stress. We examined whether uric acid, a major endogenous antioxidant in the human body, can protect against changes seen in a rat model of IBS. An experimental model of IBS was created by applying laser\u2010induced shock waves to the head, leading to increased sensitivity to colorectal distension (a measure of visceral hypersensitivity), impaired barrier function of the lower small intestine, and reduced a protective anti\u2010inflammatory signal (IL\u201010) in the gut. Increasing blood uric acid levels reduced visceral hypersensitivity, improved the barrier function of the lower small intestine, and restored IL\u201010 levels. Importantly, the uric acid\u2013induced suppression of visceral hypersensitivity was lost when vagus nerve signaling was disrupted, indicating that vagal and cholinergic signaling is involved in this effect."

Although peripheral determinants of barrier dysfunction have been studied, the contribution of central regulatory mechanisms remains unclear. \u03b2-Hydroxybutyrate (BHB), a major ketone body elevated during fasting, exhibits anti-inflammatory and barrier-protective effects peripherally, but its central actions are unknown. Here, we investigated whether BHB acts within the brain to regulate intestinal barrier function and visceral sensitivity using an LPS-induced rat model. Intracisternal BHB dose-dependently attenuated LPS-induced colonic hyperpermeability and visceral hypersensitivity, whereas an equivalent subcutaneous dose was ineffective, indicating a centrally mediated effect. The protection conferred by intracisternal BHB was abolished by vagotomy and by pharmacological inhibition of brain AMPK, orexin 1 receptors, histamine H1 receptors, basal forebrain cholinergic neurons (BFCNs), or adenosine A2B receptors. Peripheral BHB also ameliorated barrier dysfunction and visceral hypersensitivity; however, these effects persisted after vagotomy while remaining sensitive to central pharmacological blockade, suggesting engagement of shared brain signaling modules together with vagus-nonobligatory components. Collectively, these findings demonstrate that BHB regulates intestinal barrier function and visceral sensitivity through both central and peripheral mechanisms. Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways. BHB thus emerges as a neuro-metabolic signal modulating core gut-brain interaction processes and represents a promising therapeutic target for leaky gut-associated disorders, particularly IBS."

This review examines emerging evidence that the gut microbiome plays a more active and specific role in this process than previously appreciated. Dysbiosis during critical illness directly contributes to barrier dysfunction through depletion of metabolites that sustain epithelial integrity. Culture-independent approaches have revealed that gut-derived organisms are a major reservoir for secondary infection, with translocation governed by microbial virulence, community dynamics, and immune cell-mediated transport rather than barrier permeability alone. In parallel, organism-specific microbial components - including structurally diverse forms of lipopolysaccharide and bacterial DNA detected across multiple blood fractions - enter the circulation and differentially modulate host immune responses. Recent studies link circulating microbial DNA composition to distinct inflammatory phenotypes in sepsis and acute respiratory distress syndrome, suggesting these signals contribute to clinical heterogeneity. These findings support a revised framework in which translocation reflects the composition of the dysbiotic gut, not barrier integrity alone. Integrating microbial data with host phenotyping may enable more precise risk stratification and microbiome-informed therapeutic strategies in critical illness."

Residual inflammation is strongly associated with an increased risk of cardiovascular disease, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, cancer, and neurocognitive impairment. This review summarizes the current evidence on the microbiology-oriented mechanisms that sustain this state. We first outline a multifactorial network in which incomplete repair of intestinal mucosal damage, dysbiosis, reduced short-chain fatty acid production, and disturbed bile acid metabolism generate a patchy \"leaky gut.\" Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits. These inputs interact with intermittent HIV antigen expression from latent reservoirs, inflammatory cell death, chronic coinfections, lymphoid tissue fibrosis, mitochondrial dysfunction, and traditional lifestyle-related risk factors. Together, they establish a self-reinforcing gut-liver-immune axis that maintains low-grade inflammation and a procoagulant milieu under viral suppression. We then link these mechanisms to organ-specific complications and review the intervention data, focusing on early ART initiation, statin therapy, and cotrimoxazole prophylaxis as a proof-of-concept that modifying inflammatory and mucosal pressures can improve outcomes. Finally, we highlight research priorities and argue that the effective prevention of long-term complications in virally suppressed PLWH requires combination strategies targeting multiple nodes of this network, with particular attention to gut barrier repair and microbiome modulation."

"abstract_text": "ID: 42543326\nTitle: [Research progress on action mechanisms of Rheum palmatum anthraquinones in improving acute lung injury].\nAbstract: Acute lung injury(ALI) and acute respiratory distress syndrome(ARDS) are severe respiratory diseases characterized by uncontrolled inflammatory responses and disruption of the alveolar-capillary barrier. This type of disease is often triggered by multiple factors such as infection, sepsis, trauma, or inhalation injury, and the pathological process involves multiple sections including inflammatory cascade reactions, oxidative stress imbalance, abnormal activation of immune cells, and increased pulmonary microvascular permeability. Owing to their complex pathogenesis and high mortality, available clinical therapeutic approaches remain limited. Therefore, the development of safe and effective therapeutic agents to attenuate ALI has become a major focus of current research field. As a TCM, Rheum palmatum has a long history of use in clearing heat and toxins, purging the bowels, and regulating systemic inflammatory responses. In recent years, increasing attention has been paid to its therapeutic effect in ALI. RESULTS:: show that R. palmatum and its major bioactive anthraquinones, such as emodin and rhein, exert protective effects through multi-target and multi-pathway mechanisms. These mechanisms mainly include inhibition of inflammatory signaling pathways such as nuclear factor-\u03baB(NF-\u03baB), mitogen-activated protein kinase(MAPK), and NOD-like receptor protein 3(NLRP3) inflammasome, attenuation of oxidative stress response, activation of the nuclear factor erythroid 2-related factor 2(Nrf2)-mediated antioxidant defense system, regulation of programmed death in immune cells including macrophages, improvement of immunometabolic status, modulation of macrophage polarization and the gut microbiota as well as the gut-lung axis, and so on. In addition, R. palmatum has been shown to preserve the integrity of the alveolar-capillary barrier and to suppress excessive neutrophil activation and the overformation of neutrophil extracellular traps(NETs), thereby reducing inflammation amplification effect and the risk of immune microthrombi. This paper summarized the action mechanisms and research progress of R. palmatum in the treatment of ALI, aiming to elucidate the unique advantages of R. palmatum anthraquinones in intervening in the complex pathological processes of ALI through systemic regulatory networks and to provide a solid theoretical basis for the research and development of innovative R. palmatum-based medicines and their clinical combination medication."

A total of 34 active ingredients of Scutellariae Radix were screened from the TCMSP database, and 65 potential therapeutic targets were identified by combining SwissTargetPrediction and GEO data analysis. Protein-protein interaction(PPI) network construction, molecular docking, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses indicated that Scutellariae Radix might exert the anti-AS effect by modulating inflammatory responses, negatively regulating pyroptosis, and influencing the NOD-like receptor(NLRP) signaling pathway. In vivo, AS was induced in ApoE~(-/-) mice by 16-week high-fat diet feeding, followed by intervention with Scutellariae Radix extract. The results showed that Scutellariae Radix significantly attenuated lipid deposition and plaque area in the aortic wall, decreased serum levels of total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG), and increased the high-density lipoprotein cholesterol(HDL-C) level, thereby improving lipid metabolism disorders. Meanwhile, it markedly inhibited the expression of proinflammatory cytokines tumor necrosis factor-\u03b1(TNF-\u03b1), interleukin(IL)-1\u03b2, and IL-6. In addition, Scutellariae Radix significantly suppressed nuclear factor-\u03baB(NF-\u03baB) phosphorylation and downregulated the protein expression of NOD-like receptor pyrin domain-containing protein 3(NLRP3), cleaved caspase-1, and the N-terminal fragment of gasdermin D(N-GSDMD), which suggested that Scutellariae Radix effectively inhibited pyroptosis in arterial tissues. Collectively, these findings suggested that Scutellariae Radix ameliorated AS by suppressing pyroptosis in arterial tissues, attenuating inflammation, and improving lipid metabolism via regulating the NLRP3/caspase-1/GSDMD signaling pathway."

While dysregulated metabolism has long been noted in DS, the underlying cause is poorly understood and vastly understudied. To fill this critical knowledge gap, we conducted a comprehensive metabolic analysis of Dp(16)1Yey/+mice (abbreviated Dp16), a segmental duplication model carrying ~58% of the triplicated Hsa21 gene orthologs. Our multi-tissue transcriptomic analyses reveal shared and sex-specific increases in expression dosage of the triplicated genes in white and brown adipose tissues, liver, skeletal muscle, and hypothalamus. Despite sexual dimorphism in body weight, body temperature, food intake, and physical activity, Dp16 males and females share striking core phenotypes of pronounced insulin resistance, glucose intolerance, impaired lipid clearance, and dyslipidemia. Functional assessments, combined with biochemical, transcriptomic, and metabolomic analyses reveal tissue signatures of immune activation and a pro-inflammatory state, ER and oxidative stress, fibrosis, impaired glucose and fatty acid catabolism, altered lipid and bile acid profiles, and reduced mitochondrial respiratory capacity in Dp16 mice. These concerted changes disrupt homeostatic mechanisms that underpin metabolic health, contributing to systemic metabolic dysfunction. An obesogenic diet further exacerbates insulin resistance in Dp16 males and females despite divergent weight gain. The collective phenotypes broadly reflect the metabolic profile of DS. Our extensive molecular, biochemical, and physiological data provide an essential foundation for genetic dissection of dosage-sensitive genes affecting glucose and lipid metabolism, and for testing therapeutic strategies to improve metabolic outcomes in DS."

Increasing evidence supports the view of HFpEF as a systemic inflammatory syndrome driven by aging and cardiometabolic comorbidities, including obesity, hypertension, and chronic kidney disease. Within this framework, regulatory T cells (Tregs), which are essential for maintaining immune tolerance and limiting excessive inflammation, have emerged as important modulators of disease progression. However, the mechanisms underlying Treg dysfunction in HFpEF have remained poorly understood. In this issue, Srinivas et al. identify stromal interaction molecule 1 (STIM1)-dependent calcium signaling as a critical regulator of Treg instability in HFpEF. The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways. Using a cardiometabolic murine model and Treg-specific STIM1 knockout mice, they establish a causal role for Treg-intrinsic STIM1 signaling in disease development. These findings position STIM1 as a molecular link between cardiometabolic stress, immune dysregulation, and cardiac remodeling. They further support the concept that immune-cell plasticity is a major determinant of HFpEF pathogenesis and suggest that preserving Treg stability may represent a novel therapeutic strategy. Although important questions remain regarding disease timing, clinical translation, and sex-specific effects, this work advances our understanding of HFpEF as an immune-mediated disorder and identifies STIM1-dependent calcium signaling as a promising therapeutic target."

This review examines emerging evidence that the gut microbiome plays a more active and specific role in this process than previously appreciated. Dysbiosis during critical illness directly contributes to barrier dysfunction through depletion of metabolites that sustain epithelial integrity. Culture-independent approaches have revealed that gut-derived organisms are a major reservoir for secondary infection, with translocation governed by microbial virulence, community dynamics, and immune cell-mediated transport rather than barrier permeability alone. In parallel, organism-specific microbial components - including structurally diverse forms of lipopolysaccharide and bacterial DNA detected across multiple blood fractions - enter the circulation and differentially modulate host immune responses. Recent studies link circulating microbial DNA composition to distinct inflammatory phenotypes in sepsis and acute respiratory distress syndrome, suggesting these signals contribute to clinical heterogeneity. These findings support a revised framework in which translocation reflects the composition of the dysbiotic gut, not barrier integrity alone. Integrating microbial data with host phenotyping may enable more precise risk stratification and microbiome-informed therapeutic strategies in critical illness."

Residual inflammation is strongly associated with an increased risk of cardiovascular disease, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, cancer, and neurocognitive impairment. This review summarizes the current evidence on the microbiology-oriented mechanisms that sustain this state. We first outline a multifactorial network in which incomplete repair of intestinal mucosal damage, dysbiosis, reduced short-chain fatty acid production, and disturbed bile acid metabolism generate a patchy \"leaky gut.\" Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits. These inputs interact with intermittent HIV antigen expression from latent reservoirs, inflammatory cell death, chronic coinfections, lymphoid tissue fibrosis, mitochondrial dysfunction, and traditional lifestyle-related risk factors. Together, they establish a self-reinforcing gut-liver-immune axis that maintains low-grade inflammation and a procoagulant milieu under viral suppression. We then link these mechanisms to organ-specific complications and review the intervention data, focusing on early ART initiation, statin therapy, and cotrimoxazole prophylaxis as a proof-of-concept that modifying inflammatory and mucosal pressures can improve outcomes. Finally, we highlight research priorities and argue that the effective prevention of long-term complications in virally suppressed PLWH requires combination strategies targeting multiple nodes of this network, with particular attention to gut barrier repair and microbiome modulation."

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

Although peripheral determinants of barrier dysfunction have been studied, the contribution of central regulatory mechanisms remains unclear. \u03b2-Hydroxybutyrate (BHB), a major ketone body elevated during fasting, exhibits anti-inflammatory and barrier-protective effects peripherally, but its central actions are unknown. Here, we investigated whether BHB acts within the brain to regulate intestinal barrier function and visceral sensitivity using an LPS-induced rat model. Intracisternal BHB dose-dependently attenuated LPS-induced colonic hyperpermeability and visceral hypersensitivity, whereas an equivalent subcutaneous dose was ineffective, indicating a centrally mediated effect. The protection conferred by intracisternal BHB was abolished by vagotomy and by pharmacological inhibition of brain AMPK, orexin 1 receptors, histamine H1 receptors, basal forebrain cholinergic neurons (BFCNs), or adenosine A2B receptors. Peripheral BHB also ameliorated barrier dysfunction and visceral hypersensitivity; however, these effects persisted after vagotomy while remaining sensitive to central pharmacological blockade, suggesting engagement of shared brain signaling modules together with vagus-nonobligatory components. Collectively, these findings demonstrate that BHB regulates intestinal barrier function and visceral sensitivity through both central and peripheral mechanisms. Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways. BHB thus emerges as a neuro-metabolic signal modulating core gut-brain interaction processes and represents a promising therapeutic target for leaky gut-associated disorders, particularly IBS."

Rhubarb (RR) is widely applied to treat IS in the clinic. However, its underlying pharmacological mechanisms remain incompletely elucidated. To dissect the mechanism and pharmacological basis of RR's ability to ameliorate IS from the side of modulating tryptophan-kynurenine (TRP-KYN) metabolism and neuroinflammation. An embolic middle cerebral artery occlusion (MCAO) model was employed in rats to simulate human IS. Neurological deficit scores, hematoxylin-eosin, 2,3,5-triphenyltetrazolium chloride, alcian blue-periodic acid-Schiff staining, Western blotting, targeted metabolomics, immunofluorescence, and enzyme-linked immunosorbent assay were utilized to evaluate the efficacy of RR against cerebral ischemic injury, gut permeability, TRP-KYN metabolism levels, and neuroinflammation. Surface plasmon resonance and cell-based assays were further utilized to screen and validate potential bioactive ingredients of RR for the treatment of IS. In addition to mitigating cerebral ischemic damage, RR treatment substantially restored intestinal barrier function in IS rats by reducing leaky gut biomarkers, ameliorating histopathological alterations, and upregulating colonic tight junction proteins. Moreover, RR modulated TRP-KYN metabolism, concomitant with regulated expression and enzymatic activity of indoleamine 2,3-dioxygenase 1 (IDO-1) and the triggering receptor expressed on myeloid cells-1 (TREM-1) levels in both colon tissue and serum. Within the central nervous system, RR attenuated neuroinflammation triggered by MCAO through orchestrating microglial polarization and cytokine levels, accompanied by suppression of the TREM-1-mediated inflammatory signaling cascade. Chrysophanol 8-O-\u03b2-d-glucoside, rutinum, lindleyin, and (-)-catechin gallate from RR were identified as potential IDO-1 inhibitors, while rhein, lindleyin, methyl gallate, and chrysophanol 8-O-\u03b2-d-glucoside were identified as potential TREM-1 inhibitors, capable of attenuating the overexpression of IDO-1 and TREM-1 or TREM-1 and NOD-like receptor protein 3 (NLRP3). This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation. These effects are attributed to its bioactive components, including rutinum, chrysophanol 8-O-\u03b2-d-glucoside, lindleyin, (-)-catechin gallate, rhein, and methyl gallate."

Ubiquitination modification is implicated in the pathogenesis of cardiovascular diseases through diverse biological processes. However, the role of TRIM9, an E3 ubiquitin ligase, in AD remains unexplored. In this study, the expression profiles of TRIM9 and SMAD4 were analyzed using clinical samples, as well as Angiotensin II (Ang II)-induced mouse and human aortic endothelial cell (HAEC) models. Endothelial barrier function in AD was assessed through CCK-8 assays, vascular permeability measurements, immunofluorescence staining, hematoxylin-eosin and Verhoeff's van Gieson staining, and Western blot analysis. The underlying molecular mechanisms were elucidated using quantitative real-time PCR, immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and enzyme-linked immunosorbent assay (ELISA). TRIM9 was markedly overexpressed, whereas SMAD4 was significantly downregulated in AD. Knockdown of TRIM9 attenuated endothelial permeability, preserved the endothelial barrier integrity, and inhibited pyroptosis both in vivo and in vitro. Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression. Collectively, these findings demonstrate that elevated TRIM9 expression aggravates AD progression through SMAD4 destabilization, offering novel therapeutic insights for AD management."

Although irritable bowel syndrome (IBS) is considered a disorder of gut-brain interaction, the role of UA in IBS remains unclear. An experimental rat model of IBS was induced using laser-induced shock waves (LISW) applied to the head. Hyperuricemia (HUA) was induced by intraperitoneal administration of inosine monophosphate and potassium oxonate. Visceral hypersensitivity was assessed by colorectal distension. Ileal mucosal permeability was measured using the Evans blue method. CRFR1 mRNA expression in the rectum, IL-10 and TGF-\u03b21 expression in the ileum, and IL-1\u03b1, IL-1\u03b2, and TNF expression in the medial prefrontal cortex (mPFC) and paraventricular nucleus (PVN) were quantified by qRT-PCR. Vagal involvement was assessed using subdiaphragmatic vagotomy or atropine treatment. LISW increased visceral hypersensitivity, ileal mucosal permeability, and rectal CRFR1 expression and reduced IL-10 expression in the ileum. HUA significantly ameliorated these changes. HUA was also associated with reduced IL-1\u03b2 expression in the mPFC and reduced IL-1\u03b1 and IL-1\u03b2 expression in the PVN in LISW-treated animals. Importantly, the ameliorative effects of HUA on visceral hypersensitivity were abolished by vagotomy or atropine treatment. Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain. The loss of HUA-induced suppression of visceral hypersensitivity after vagotomy or atropine treatment suggests the possible involvement of vagal and cholinergic brain-gut communication. Irritable bowel syndrome (IBS) is a common disorder in which people experience abdominal pain and bowel problems, often worsened by stress. We examined whether uric acid, a major endogenous antioxidant in the human body, can protect against changes seen in a rat model of IBS. An experimental model of IBS was created by applying laser\u2010induced shock waves to the head, leading to increased sensitivity to colorectal distension (a measure of visceral hypersensitivity), impaired barrier function of the lower small intestine, and reduced a protective anti\u2010inflammatory signal (IL\u201010) in the gut. Increasing blood uric acid levels reduced visceral hypersensitivity, improved the barrier function of the lower small intestine, and restored IL\u201010 levels. Importantly, the uric acid\u2013induced suppression of visceral hypersensitivity was lost when vagus nerve signaling was disrupted, indicating that vagal and cholinergic signaling is involved in this effect."

However, the adoption of plant-based alternatives depends on multiple factors, including consumer preferences, sensory quality, product affordability, and availability, in addition to sustainability and ethical considerations. Although nondairy yogurt alternatives may offer environmental advantages over conventional dairy products, their broader adoption is often constrained by textural limitations, which remain a major barrier to consumer acceptance. Addressing texture deficiencies requires strategic ingredient selection and optimized processing techniques. While existing literature focuses primarily on plant-based systems, alternative protein sources such as fungal proteins remain underexplored, with few studies evaluating fungal protein-based yogurt analogues. This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy. Compared with many heteropolysaccharides often produced at relatively low yields by yogurt starters, dextran, a homopolysaccharide, can be synthesized at higher levels by certain lactic acid bacteria (LAB) and contributes to enhanced viscosity and gel formation in plant-based matrices. We discuss the mechanisms underlying these effects, including dextran-protein interactions and water-binding capacity, as well as their relevance to clean-label and functional food trends. Key research priorities include identifying food-grade, high-yield dextran-producing LAB strains, assessing their safety and allergenicity, and investigating the digestive fate and health effects of in situ-produced dextrans. Overall, in situ dextran production represents a promising strategy for improving the texture and consumer acceptance of nondairy yogurt alternatives."

Discriminant metabolites, including suberic acid, gluconic acid, heptadecane, and tartaric acid, distinguished experimental groups, capturing key features of the metabolic response to dopaminergic injury and treatment. Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways. Propolis treatment attenuated the elevation of suberic acid, accompanied by a reduction in gluconic acid levels, suggesting a metabolic profile linked to pathways involved in redox balance and glucose handling. Given previous reports identifying heptadecane as a hydrocarbon constituent of volatile propolis fractions, complementary GC-Q-TOF analyses demonstrated that heptadecane was absent from the administered extract, despite its consistent association with propolis-treated groups. Metabolic changes were accompanied by attenuation of nigrostriatal dopaminergic neurodegeneration and improved motor performance. Together, these findings delineate a striatal metabolic signature associated with Brazilian green propolis and identify suberic acid as a key metabolite linked to neuroprotection in experimental Parkinsonism."

The optimal preparation process of HPSCH was investigated by using schisandrin content and total extractive yield as indices. After one week of adaptive feeding, C57BL/6 mice were assigned to a normal control group, while the remaining mice were fed an HFD for eight weeks to establish the NAFLD mouse model. After being successfully modeled, the mice were divided into a blank control group, blank administration group, simple model group, fenofibrate group, SCH group, and HPSCH group. All groups were administered by intragastric administration for four weeks. Body weight changes of mice were recorded, and liver indices were calculated. The levels of blood lipid and liver function index in the serum of mice were measured. Hepatic histopathological changes were observed by using hematoxylin-eosin(HE) staining and oil red O staining. Mice's feces were collected, and the 16S rDNA high-throughput sequencing method was employed to analyze changes in the gut microbiota of mice. Untargeted lipidomic analysis of the liver was conducted by using liquid chromatography-mass spectrometry(LC-MS), and principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were adopted to screen and identify differential metabolites. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to perform relevant pathway analysis. Integrated analyses of gut microbiota and differential metabolites were performed to compare the similarities and differences in efficacy of HPSCH and SCH. The results show that both the HPSCH group and SCH group exert similar effects on biochemical indices in serum and hepatic pathological changes, lipid metabolism can be regulated, and liver injury in NAFLD mice can be improved. The two groups show similar changes in microbial abundance, trending toward the blank control group and maintaining intestinal homeostasis. Compared with those of the simple model group, the differential metabolites and metabolic pathways of both the HPSCH group and SCH group show similarity, and the differential metabolites are mainly triglycerides, diglycerides, phosphatidylcholines, phosphatidylglycerols, and so on. Metabolic pathways include glycerophospholipid metabolism, choline metabolism, retrograde endocannabinoid signaling, thermogenic lipolysis, and so on. This indicates that HPSCH and SCH share common advantages in improving hepatic function in mice and achieve comparable effects. HPSCH can improve blood lipid and liver function indices in NAFLD mice, attaining the therapeutic effect through the regulation of gut microbiota and lipid metabolism. Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application. Moreover, the application of HPSCH may contribute to the conservation of medicinal resources."

A total of 34 active ingredients of Scutellariae Radix were screened from the TCMSP database, and 65 potential therapeutic targets were identified by combining SwissTargetPrediction and GEO data analysis. Protein-protein interaction(PPI) network construction, molecular docking, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses indicated that Scutellariae Radix might exert the anti-AS effect by modulating inflammatory responses, negatively regulating pyroptosis, and influencing the NOD-like receptor(NLRP) signaling pathway. In vivo, AS was induced in ApoE~(-/-) mice by 16-week high-fat diet feeding, followed by intervention with Scutellariae Radix extract. The results showed that Scutellariae Radix significantly attenuated lipid deposition and plaque area in the aortic wall, decreased serum levels of total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG), and increased the high-density lipoprotein cholesterol(HDL-C) level, thereby improving lipid metabolism disorders. Meanwhile, it markedly inhibited the expression of proinflammatory cytokines tumor necrosis factor-\u03b1(TNF-\u03b1), interleukin(IL)-1\u03b2, and IL-6. In addition, Scutellariae Radix significantly suppressed nuclear factor-\u03baB(NF-\u03baB) phosphorylation and downregulated the protein expression of NOD-like receptor pyrin domain-containing protein 3(NLRP3), cleaved caspase-1, and the N-terminal fragment of gasdermin D(N-GSDMD), which suggested that Scutellariae Radix effectively inhibited pyroptosis in arterial tissues.

While dysregulated metabolism has long been noted in DS, the underlying cause is poorly understood and vastly understudied. To fill this critical knowledge gap, we conducted a comprehensive metabolic analysis of Dp(16)1Yey/+mice (abbreviated Dp16), a segmental duplication model carrying ~58% of the triplicated Hsa21 gene orthologs. Our multi-tissue transcriptomic analyses reveal shared and sex-specific increases in expression dosage of the triplicated genes in white and brown adipose tissues, liver, skeletal muscle, and hypothalamus. Despite sexual dimorphism in body weight, body temperature, food intake, and physical activity, Dp16 males and females share striking core phenotypes of pronounced insulin resistance, glucose intolerance, impaired lipid clearance, and dyslipidemia. Functional assessments, combined with biochemical, transcriptomic, and metabolomic analyses reveal tissue signatures of immune activation and a pro-inflammatory state, ER and oxidative stress, fibrosis, impaired glucose and fatty acid catabolism, altered lipid and bile acid profiles, and reduced mitochondrial respiratory capacity in Dp16 mice. These concerted changes disrupt homeostatic mechanisms that underpin metabolic health, contributing to systemic metabolic dysfunction. An obesogenic diet further exacerbates insulin resistance in Dp16 males and females despite divergent weight gain. The collective phenotypes broadly reflect the metabolic profile of DS. Our extensive molecular, biochemical, and physiological data provide an essential foundation for genetic dissection of dosage-sensitive genes affecting glucose and lipid metabolism, and for testing therapeutic strategies to improve metabolic outcomes in DS."

Increasing evidence supports the view of HFpEF as a systemic inflammatory syndrome driven by aging and cardiometabolic comorbidities, including obesity, hypertension, and chronic kidney disease. Within this framework, regulatory T cells (Tregs), which are essential for maintaining immune tolerance and limiting excessive inflammation, have emerged as important modulators of disease progression. However, the mechanisms underlying Treg dysfunction in HFpEF have remained poorly understood. In this issue, Srinivas et al. identify stromal interaction molecule 1 (STIM1)-dependent calcium signaling as a critical regulator of Treg instability in HFpEF. The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways. Using a cardiometabolic murine model and Treg-specific STIM1 knockout mice, they establish a causal role for Treg-intrinsic STIM1 signaling in disease development. These findings position STIM1 as a molecular link between cardiometabolic stress, immune dysregulation, and cardiac remodeling. They further support the concept that immune-cell plasticity is a major determinant of HFpEF pathogenesis and suggest that preserving Treg stability may represent a novel therapeutic strategy. Although important questions remain regarding disease timing, clinical translation, and sex-specific effects, this work advances our understanding of HFpEF as an immune-mediated disorder and identifies STIM1-dependent calcium signaling as a promising therapeutic target."

We previously introduced ByeTACs, bifunctional molecules that directly recruit proteins to the proteasome for E-ligase independent degradation. Here, we report \"Truly\" degraders, a new class of dual-mechanism molecules that combine a ligand for the proteasomal receptor Rpn13 with a ligand for cereblon (CRBN) to simultaneously engage both ubiquitin-independent and ubiquitin-dependent degradation pathways. Structure-guided design identified an optimal linker length that supports efficient substrate processing, with the PEG4 derivative (Truly-4) inducing robust depletion of both Rpn13 and CRBN in several cancer cell types. Remarkably, Truly-4 is the first noncovalent small molecule shown to degrade full-length Rpn13, a target previously approached using covalent or domain-restricted strategies. Mechanistic studies confirmed that degradation of Rpn13 proceeds via CRBN-dependent E3 ligase activity, whereas CRBN degradation occurs through an E-ligase independent process, consistent with a ByeTAC mechanism. Importantly, Truly-4 induces selective cytotoxicity in hematologic and solid cancer cell lines but not in healthy cells, despite comparable Rpn13 depletion, indicating that dual degradation can uncouple target engagement from toxicity. These findings establish a generalizable framework for engineering bifunctional degraders that program the proteasome to execute parallel degradation mechanisms and highlight proteasome receptors as druggable nodes for selective destruction of disease-relevant proteins."

Yet the oversimplified concept of 'leaky gut' as a singular phenomenon has limited both mechanistic understanding and therapeutic development. It is now recognized that intestinal permeability occurs via two molecularly distinct, differentially regulated trans-tight junction pathways, while a tight junction-independent unrestricted pathway allows flux at sites of epithelial damage. The pore pathway is a high-conductance, size-selective and charge-selective flux route that mediates ion and water flux. Its upregulation can be either protective, as in infectious enterocolitis, or pathogenic, as in immune-mediated disease or, as shown recently, in sepsis. Myosin light chain kinase activation enhances flux across the leak pathway, a low-conductance macromolecular flux route, that promotes progression of immune-mediated diseases. Recently developed molecularly targeted, pathway-specific approaches to barrier restoration are effective and can outperform current therapies without the complications of broad immunosuppression. The evolving pathway-resolved framework transforms intestinal barrier biology from a descriptive science into mechanism-specific therapeutic approaches that have promise as independent agents and as complements to available immune-targeted therapies."

Strength training (ST) combined with adequate protein intake is a key element in reversing and improving functional capacity. Protein, especially Whey Protein isolates (WPI), is widely used to improve muscle mass. In contrast, high-protein products, such as protein yogurt (PY), may offer similar benefits for muscle health and drive additional effects on gut health, which is altered in older adults. For this, we aim to compare WP and PY supplementation during ST on body composition, strength, and gut microbiome in untrained older adults.\u00a0Seventeen untrained adults (60-70 years) were randomized to either consume WP (25 g) or PY (24.5 g) along with an 8-week supervised ST program (3 sessions/week). Initial and final assessments included body composition (BIA), strength (10RM, isokinetic torque, handgrip), gait speed, resting metabolic rate, and gut microbiome (16 S rRNA sequencing). Data were analyzed using repeated-measures ANOVA and diversity metrics. Both groups increased skeletal muscle mass (WP: +0.47 kg; PY: +0.50 kg) and improved strength and gait speed (p\u2009<\u20090.01), with no between-group differences. Fat mass decreased only in WP (p\u2009=\u20090.02), while resting metabolic rate increased in PY (p\u2009=\u20090.03). Microbiome analysis revealed distinct shifts: WP increased the Firmicutes/Bacteroidota ratio and enriched Subdoligranulum, whereas PY enhanced alpha diversity and increased the abundance of Coprococcus. Functional pathway predictions indicated differential enrichment in metabolic and signaling processes. High-protein yogurt and whey protein similarly improve muscle mass, strength, and functional capacity during ST, while exerting distinct effects on gut microbiome composition. Yogurt represents a cost-effective alternative to whey protein and may confer additional gut health benefits.Trial registration: Clinicaltrials.gov identifier NCT06412302.

Despite their broad consumption, systematic comparisons of their biochemical characteristics remain limited. In this study, integrated untargeted and targeted metabolomics approaches were applied to compare the comprehensive metabolite profiles of PS and YG. PS exhibited relatively higher levels of amino acids, dicarboxylic acids, and lysophospholipids, along with short-chain fatty acids such as acetate and propionate, and amino acid-derived bioactive metabolites, including \u03b3-aminobutyric acid, branched-chain hydroxy acids, indole derivatives, and \u03b3-glutamylpeptides.

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis."

We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference.

However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation."

ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC. These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication."

Probiotic supplementation represents a microbiota-targeted nutritional strategy for functional constipation, but associated host-response signals remain incompletely understood. This single-center, randomized, double-blind, placebo-controlled trial enrolled 104 adults who met the Rome IV criteria for functional constipation. Participants received either Lactiplantibacillus plantarum Probio87 or placebo for 8\u202fweeks, followed by a 4-week post-intervention follow-up. The primary endpoint was weekly complete spontaneous bowel movements. Secondary outcomes included Rome IV symptom scores, PAC-QOL, HAMD-24, safety parameters, and exploratory whole-blood gene-expression profiles related to inflammation, immune regulation, neuroendocrine signaling, and gut motility. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300075360). Probio87 supplementation significantly increased weekly complete spontaneous bowel movements compared with placebo at Week 8 and Week 12. Improvements were also observed in Rome IV symptom scores, constipation-related quality of life, and HAMD-24 domains related to anxiety, sleep, and retardation. Exploratory whole-blood gene-expression analysis showed differential host-response signals after intervention, characterized by increased BDNF expression and reduced expression of IL-1\u03b2, CD117, CXCR5, IDO1, DBH, and MLNR in the probiotic group relative to placebo. No intervention-related adverse events or clinically relevant abnormalities in hematological, hepatic, or renal safety parameters were observed. L. plantarum Probio87 supplementation was associated with sustained improvement in bowel function, constipation-related quality of life, and psychological well-being in adults with functional constipation. Exploratory peripheral gene-expression findings suggest that inflammatory, immune, neuroendocrine, and motility-related host-response pathways may be involved, although causal mechanisms require further validation. https://www.chictr.org.cn/showproj.html?proj=205514, identifier (ChiCTR2300075360)."

This review advances an effector-centered framework to explain how A. muciniphila acts through host-facing molecules, including outer membrane and secreted proteins such as Amuc_1100 (pilus-associated signaling, PAS) and P9, extracellular vesicles (EVs) and outer membrane vesicles (OMVs), and shed cell-envelope fragments and lipids. We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release. Key gaps include physiological dose realism, equivalence across colony-forming units (CFU) and protein or vesicle doses, strain and culture-condition dependence of effector expression, and limited human data for brain-relevant endpoints. Effector-defined preparations and engineered delivery systems may improve standardization and safety, but translation will require rigorous characterization, dose-response validation, and mechanism-linked biomarkers."

This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility."

"abstract_text": "ID: 42529162\nTitle: Reframing brain aging: neuroinflammation as an interconnected network process.\nAbstract: Neuroinflammation has emerged as a central component of brain aging, shaping the balance between neural resilience and vulnerability to cognitive decline. Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health."

Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression.

"abstract_text": "ID: 42505396\nTitle: Mediterranean Diet and Neurodegenerative Diseases: Recent Advances from the Gut-Immune-Brain Axis to Multi-Omics-Guided Precision Nutrition.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD) are regarded as systemic illnesses, mainly characterized by long-term neuroinflammation, metabolic dysregulation and barrier dysfunction. All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice."

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."

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management."

Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications."

In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS).

Overall, this study provides theoretical insights into the metabolic adaptations of frugivorous bats and the glucose-response strategies of insectivorous bats, offering new perspectives on metabolite-based therapeutic approaches to diabetes. \u73b0\u6709\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u624b\u6bb5\u4ecd\u7136\u6709\u9650\uff0c\u4e9f\u9700\u63a2\u7d22\u8840\u7cd6\u8c03\u63a7\u7684\u65b0\u673a\u5236\u3002\u8759\u8760\u5177\u6709\u9ad8\u5ea6\u591a\u6837\u5316\u7684\u98df\u6027\uff0c\u4e14\u666e\u904d\u8868\u73b0\u51fa\u8f83\u957f\u7684\u5bff\u547d\u7279\u5f81\uff0c\u8fd9\u4f7f\u5176\u6210\u4e3a\u7814\u7a76\u964d\u8840\u7cd6\u8c03\u63a7\u673a\u5236\u7684\u7406\u60f3\u6a21\u578b\u3002\u672c\u7814\u7a76\u5bf9\u4e94\u79cd\u8759\u8760\u5f00\u5c55\u4e86\u8179\u8154\u8461\u8404\u7cd6\u8010\u91cf\u8bd5\u9a8c\uff0c\u5176\u4e2d\u5305\u62ec\u4e09\u79cd\u98df\u679c\u6216\u98df\u871c\u8759\u8760\uff08\u9274\u4e8e\u6c34\u679c\u548c\u82b1\u871c\u5747\u5177\u6709\u8f83\u9ad8\u7684\u7cd6\u542b\u91cf\uff0c\u4e0b\u6587\u7edf\u79f0\u4e3a\u98df\u679c\u6027\u8759\u8760\uff09\u4ee5\u53ca\u4e24\u79cd\u98df\u866b\u8759\u8760\u3002\u91c7\u7528\u6db2\u76f8\u8272\u8c31-\u7535\u55b7\u96fe\u7535\u79bb-\u4e32\u8054\u8d28\u8c31\u6280\u672f\uff08LC-ESI-MS/MS\uff09\u5bf9\u9ad8\u7cd6\u523a\u6fc0\u4e4b\u4e0b\u8759\u8760\u8840\u6e05\u4e2d\u5171704\u79cd\u5df2\u77e5\u4ee3\u8c22\u7269\u8fdb\u884c\u4e86\u5b9a\u91cf\u5206\u6790\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u9ad8\u7cd6\u523a\u6fc0\u4e0b\uff0c\u4e0e\u98df\u866b\u8759\u8760\u76f8\u6bd4\uff0c\u98df\u679c\u8759\u8760\u4f53\u5185\u591a\u79cd\u6c28\u57fa\u9178\u76f8\u5173\u4ee3\u8c22\u7269\u6c34\u5e73\u663e\u8457\u5347\u9ad8\uff0c\u4e3b\u8981\u7c7b\u522b\u5305\u62ecN-\u9170\u57fa\u6c28\u57fa\u9178\u3001\u82b3\u9999\u65cf\u6c28\u57fa\u9178\u884d\u751f\u7269\u4ee5\u53ca\u652f\u94fe\u6c28\u57fa\u9178\u4ee3\u8c22\u7269\uff0c\u8fd9\u4e9b\u4ee3\u8c22\u7269\u663e\u8457\u5bcc\u96c6\u4e8e\u4e19\u6c28\u9178\u3001\u7cbe\u6c28\u9178\u548cD-\u6c28\u57fa\u9178\u4ee3\u8c22\u7b49\u901a\u8def\u3002\u6b64\u5916\uff0c\u591a\u79cd\u5df2\u77e5\u7684\u80a0-\u8111\u8f74\u76f8\u5173\u4ee3\u8c22\u7269\uff08\u5982\u795e\u7ecf\u9012\u8d28\u3001\u80c6\u6c41\u9178\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff09\u8868\u73b0\u51fa\u663e\u8457\u7684\u5bbf\u4e3b\u98df\u6027\u548c\u7269\u79cd\u6c34\u5e73\u7684\u7279\u5f02\u6027\u2014\u2014\u98df\u679c\u8759\u8760\u5bcc\u96c6\u4e86\u66f4\u591a\u7684\u4e0e\u80f0\u5c9b\u7d20\u8c03\u63a7\u76f8\u5173\u7684\u795e\u7ecf\u9012\u8d28\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff0c\u800c\u98df\u866b\u8759\u8760\u5219\u8868\u73b0\u51fa\u6c34\u5e73\u76f8\u5bf9\u66f4\u9ad8\u7684\u80c6\u6c41\u9178\u4ee3\u8c22\u7269\u3002\u603b\u4f53\u800c\u8a00\uff0c\u672c\u7814\u7a76\u4e3a\u63ed\u793a\u98df\u679c\u8759\u8760\u7684\u4ee3\u8c22\u9002\u5e94\u673a\u5236\u53ca\u98df\u866b\u8759\u8760\u7684\u8461\u8404\u7cd6\u5e94\u7b54\u7b56\u7565\u63d0\u4f9b\u4e86\u66f4\u591a\u7406\u8bba\u4f9d\u636e\uff0c\u5e76\u4e3a\u57fa\u4e8e\u4ee3\u8c22\u7269\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u89c6\u89d2\u3002."

Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk."

Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury."

Because increased dietary fat intake can both trigger IBS symptoms and promote LPS translocation in the gut, this study aimed to better understand how a turmeric formula (TF) affects fasting and postprandial LPS response, after a high-fat challenge in patients with IBS (primary outcome). Secondary outcomes included postprandial ApolipoproteinB48 (Apo-B48) and triglycerides (TG) as markers of chylomicron-mediated LPS translocation, as well as gastrointestinal (GI) symptoms and stool pattern. In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients."

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis. Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection."

"abstract_text": "ID: 42531833\nTitle: Poricoic acid a ameliorates ulcerative colitis via AMPK/PPAR\u03b3 pathway-dependent cellular senescence inhibition and concomitant gut microbiota-metabolome modulation.\nAbstract: Ulcerative colitis (UC) is an intractable inflammatory bowel disorder characterized by persistent intestinal inflammation and impaired gut barrier integrity. Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis."

Mela Rosa Marchigiana Preserves Intestinal Barrier Integrity and Confers Neuroprotection in a Gut-Brain Axis Co-Culture Model.\nAbstract: The gut-brain axis is a key target in neuroinflammatory disorders. We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference. These findings suggest MRME as a promising nutraceutical candidate for gut-brain axis dysregulation."

"abstract_text": "ID: 42528699\nTitle: Gut-brain axis mechanisms of remote brain dysfunction after traumatic spinal cord injury: immune inflammation, the vagus nerve, and neuroendocrine pathways.\nAbstract: Traumatic spinal cord injury (SCI) has traditionally been regarded as a central nervous system injury mainly confined to the injured segment. However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation."

ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC. These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication."

Probiotic supplementation represents a microbiota-targeted nutritional strategy for functional constipation, but associated host-response signals remain incompletely understood. This single-center, randomized, double-blind, placebo-controlled trial enrolled 104 adults who met the Rome IV criteria for functional constipation. Participants received either Lactiplantibacillus plantarum Probio87 or placebo for 8\u202fweeks, followed by a 4-week post-intervention follow-up. The primary endpoint was weekly complete spontaneous bowel movements. Secondary outcomes included Rome IV symptom scores, PAC-QOL, HAMD-24, safety parameters, and exploratory whole-blood gene-expression profiles related to inflammation, immune regulation, neuroendocrine signaling, and gut motility. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300075360). Probio87 supplementation significantly increased weekly complete spontaneous bowel movements compared with placebo at Week 8 and Week 12. Improvements were also observed in Rome IV symptom scores, constipation-related quality of life, and HAMD-24 domains related to anxiety, sleep, and retardation. Exploratory whole-blood gene-expression analysis showed differential host-response signals after intervention, characterized by increased BDNF expression and reduced expression of IL-1\u03b2, CD117, CXCR5, IDO1, DBH, and MLNR in the probiotic group relative to placebo. No intervention-related adverse events or clinically relevant abnormalities in hematological, hepatic, or renal safety parameters were observed. L. plantarum Probio87 supplementation was associated with sustained improvement in bowel function, constipation-related quality of life, and psychological well-being in adults with functional constipation. Exploratory peripheral gene-expression findings suggest that inflammatory, immune, neuroendocrine, and motility-related host-response pathways may be involved, although causal mechanisms require further validation. https://www.chictr.org.cn/showproj.html?proj=205514, identifier (ChiCTR2300075360)."

This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility."

"abstract_text": "ID: 42529162\nTitle: Reframing brain aging: neuroinflammation as an interconnected network process.\nAbstract: Neuroinflammation has emerged as a central component of brain aging, shaping the balance between neural resilience and vulnerability to cognitive decline. Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health."

Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression.

"abstract_text": "ID: 42505396\nTitle: Mediterranean Diet and Neurodegenerative Diseases: Recent Advances from the Gut-Immune-Brain Axis to Multi-Omics-Guided Precision Nutrition.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD) are regarded as systemic illnesses, mainly characterized by long-term neuroinflammation, metabolic dysregulation and barrier dysfunction. All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice."

Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications."

Bats despite diverse dietary habits, making them ideal models for studying hypoglycemic mechanisms. In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Compared with insectivorous bats, frugivorous bats exhibited significantly higher levels of amino acid-related metabolites under high-glucose stimulation. These included N-acyl amino acids, aromatic amino acid derivatives, and branched-chain amino acid metabolites, which were enriched significantly in pathways, such as alanine, arginine, and D-amino acid metabolism. Additionally, several known gut-brain axis (GBA) metabolites-such as neurotransmitters, bile acids, and short-chain fatty acids-exhibited strong host dietary and species specificity. Frugivorous bats were enriched in neurotransmitters and short-chain fatty acids associated with insulin regulation, whereas insectivorous bats exhibited relatively higher levels of bile acid metabolites.

Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk."

Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury."

In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients."

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."

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management."

This review advances an effector-centered framework to explain how A. muciniphila acts through host-facing molecules, including outer membrane and secreted proteins such as Amuc_1100 (pilus-associated signaling, PAS) and P9, extracellular vesicles (EVs) and outer membrane vesicles (OMVs), and shed cell-envelope fragments and lipids. We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release.

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis.

Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis."

We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference.

However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation."

ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC.

This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility."

Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health."

Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression.

All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice."

"abstract_text": "ID: 42207404\nTitle: Targeting Gut Microbiota by DPP-4 Inhibitors in Obesity: Mechanistic Insights and Therapeutic Implications.\nAbstract: Obesity is a complex metabolic disorder driven by factors such as chronic inflammation, insulin resistance, and significant alterations in the gut microbiota. Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications."

Bats despite diverse dietary habits, making them ideal models for studying hypoglycemic mechanisms. In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Compared with insectivorous bats, frugivorous bats exhibited significantly higher levels of amino acid-related metabolites under high-glucose stimulation. These included N-acyl amino acids, aromatic amino acid derivatives, and branched-chain amino acid metabolites, which were enriched significantly in pathways, such as alanine, arginine, and D-amino acid metabolism. Additionally, several known gut-brain axis (GBA) metabolites-such as neurotransmitters, bile acids, and short-chain fatty acids-exhibited strong host dietary and species specificity. Frugivorous bats were enriched in neurotransmitters and short-chain fatty acids associated with insulin regulation, whereas insectivorous bats exhibited relatively higher levels of bile acid metabolites. Overall, this study provides theoretical insights into the metabolic adaptations of frugivorous bats and the glucose-response strategies of insectivorous bats, offering new perspectives on metabolite-based therapeutic approaches to diabetes. \u73b0\u6709\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u624b\u6bb5\u4ecd\u7136\u6709\u9650\uff0c\u4e9f\u9700\u63a2\u7d22\u8840\u7cd6\u8c03\u63a7\u7684\u65b0\u673a\u5236\u3002\u8759\u8760\u5177\u6709\u9ad8\u5ea6\u591a\u6837\u5316\u7684\u98df\u6027\uff0c\u4e14\u666e\u904d\u8868\u73b0\u51fa\u8f83\u957f\u7684\u5bff\u547d\u7279\u5f81\uff0c\u8fd9\u4f7f\u5176\u6210\u4e3a\u7814\u7a76\u964d\u8840\u7cd6\u8c03\u63a7\u673a\u5236\u7684\u7406\u60f3\u6a21\u578b\u3002\u672c\u7814\u7a76\u5bf9\u4e94\u79cd\u8759\u8760\u5f00\u5c55\u4e86\u8179\u8154\u8461\u8404\u7cd6\u8010\u91cf\u8bd5\u9a8c\uff0c\u5176\u4e2d\u5305\u62ec\u4e09\u79cd\u98df\u679c\u6216\u98df\u871c\u8759\u8760\uff08\u9274\u4e8e\u6c34\u679c\u548c\u82b1\u871c\u5747\u5177\u6709\u8f83\u9ad8\u7684\u7cd6\u542b\u91cf\uff0c\u4e0b\u6587\u7edf\u79f0\u4e3a\u98df\u679c\u6027\u8759\u8760\uff09\u4ee5\u53ca\u4e24\u79cd\u98df\u866b\u8759\u8760\u3002\u91c7\u7528\u6db2\u76f8\u8272\u8c31-\u7535\u55b7\u96fe\u7535\u79bb-\u4e32\u8054\u8d28\u8c31\u6280\u672f\uff08LC-ESI-MS/MS\uff09\u5bf9\u9ad8\u7cd6\u523a\u6fc0\u4e4b\u4e0b\u8759\u8760\u8840\u6e05\u4e2d\u5171704\u79cd\u5df2\u77e5\u4ee3\u8c22\u7269\u8fdb\u884c\u4e86\u5b9a\u91cf\u5206\u6790\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u9ad8\u7cd6\u523a\u6fc0\u4e0b\uff0c\u4e0e\u98df\u866b\u8759\u8760\u76f8\u6bd4\uff0c\u98df\u679c\u8759\u8760\u4f53\u5185\u591a\u79cd\u6c28\u57fa\u9178\u76f8\u5173\u4ee3\u8c22\u7269\u6c34\u5e73\u663e\u8457\u5347\u9ad8\uff0c\u4e3b\u8981\u7c7b\u522b\u5305\u62ecN-\u9170\u57fa\u6c28\u57fa\u9178\u3001\u82b3\u9999\u65cf\u6c28\u57fa\u9178\u884d\u751f\u7269\u4ee5\u53ca\u652f\u94fe\u6c28\u57fa\u9178\u4ee3\u8c22\u7269\uff0c\u8fd9\u4e9b\u4ee3\u8c22\u7269\u663e\u8457\u5bcc\u96c6\u4e8e\u4e19\u6c28\u9178\u3001\u7cbe\u6c28\u9178\u548cD-\u6c28\u57fa\u9178\u4ee3\u8c22\u7b49\u901a\u8def\u3002\u6b64\u5916\uff0c\u591a\u79cd\u5df2\u77e5\u7684\u80a0-\u8111\u8f74\u76f8\u5173\u4ee3\u8c22\u7269\uff08\u5982\u795e\u7ecf\u9012\u8d28\u3001\u80c6\u6c41\u9178\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff09\u8868\u73b0\u51fa\u663e\u8457\u7684\u5bbf\u4e3b\u98df\u6027\u548c\u7269\u79cd\u6c34\u5e73\u7684\u7279\u5f02\u6027\u2014\u2014\u98df\u679c\u8759\u8760\u5bcc\u96c6\u4e86\u66f4\u591a\u7684\u4e0e\u80f0\u5c9b\u7d20\u8c03\u63a7\u76f8\u5173\u7684\u795e\u7ecf\u9012\u8d28\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff0c\u800c\u98df\u866b\u8759\u8760\u5219\u8868\u73b0\u51fa\u6c34\u5e73\u76f8\u5bf9\u66f4\u9ad8\u7684\u80c6\u6c41\u9178\u4ee3\u8c22\u7269\u3002\u603b\u4f53\u800c\u8a00\uff0c\u672c\u7814\u7a76\u4e3a\u63ed\u793a\u98df\u679c\u8759\u8760\u7684\u4ee3\u8c22\u9002\u5e94\u673a\u5236\u53ca\u98df\u866b\u8759\u8760\u7684\u8461\u8404\u7cd6\u5e94\u7b54\u7b56\u7565\u63d0\u4f9b\u4e86\u66f4\u591a\u7406\u8bba\u4f9d\u636e\uff0c\u5e76\u4e3a\u57fa\u4e8e\u4ee3\u8c22\u7269\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u89c6\u89d2\u3002."

Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk."

Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury."

Because increased dietary fat intake can both trigger IBS symptoms and promote LPS translocation in the gut, this study aimed to better understand how a turmeric formula (TF) affects fasting and postprandial LPS response, after a high-fat challenge in patients with IBS (primary outcome). Secondary outcomes included postprandial ApolipoproteinB48 (Apo-B48) and triglycerides (TG) as markers of chylomicron-mediated LPS translocation, as well as gastrointestinal (GI) symptoms and stool pattern. In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients."

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management."

We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release.

Xinqingning Tablet (XQNT) demonstrates neuroprotective potential in IS complicated by gut dysbiosis (GD), yet its mechanisms of GBA modulation remain unclear. A dual-hit IS-GD mouse model was established via fecal slurry transplantation and permanent middle cerebral artery occlusion (pMCAO) surgery. Gut function was evaluated by constipation indices and histopathological changes, while the neuroprotective efficacy of XQNT (0.36, 0.48, and 0.61 g kg\u207b\u00b9) was assessed via TTC staining, neurological deficit scores, cerebral water content, and Evans blue (EB) extravasation assays. Additionally, Western blot was employed to quantify blood-brain barrier (BBB) and inflammation-associated proteins. microRNA sequencing was used to screen the differentially expressed miRNAs. miR-126 expression levels were measured by RT-qPCR, while concentrations of LPS, IL-6 and IL-10 were determined by ELISA. Finally, mechanistic validation employed intravenous miR-126 agonism/antagonism coupled with phenotypic rescue experiments. XQNT conferred robust survival benefits, while concurrently ameliorating intestinal dysfunction and neurovascular injury. Mechanistically, XQNT elevated miR-126 expression, suppressing NF-\u03baB-driven neuroinflammation. Additionally, miR-126 agonism phenocopied XQNT efficacy, whereas miR-126 inhibition abrogated therapeutic benefits. This study provides early evidence that XQNT functions as a dual-target GBA modulator that alleviates IS with GD via regulation of the miR-126/NF-\u03baB axis. By simultaneously promoting barrier restoration and inflammatory resolution, XQNT offers a promising therapeutic approach that links regulation of the gastrointestinal system with cerebrovascular protection."

However, the provided literature extensively documents gut-brain axis mechanisms\u2014such as the modulation of intestinal permeability, the suppression of proinflammatory signaling, and the activation of metabolic pathways like the PI3K/Akt/Nrf2 or AMPK-orexin axis\u2014that are currently being repurposed as therapeutic targets in neurodegenerative diseases.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe claim concerning \"Almased\" is unsubstantiated by the provided literature. The investigation focuses on whether metabolic modulators identified in the text (e.g., bioactive plant extracts, metabolites like \u03b2-hydroxybutyrate, or specific fermentation products) can be repurposed as neuroprotective agents via the restoration of intestinal barrier integrity and modulation of gut-brain signaling, a valid scientific inquiry supported by the text.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent research suggests that systemic metabolic health is fundamentally coupled to gut barrier integrity. Pathological increases in intestinal permeability, often termed \"leaky gut,\" allow microbial products to enter systemic circulation, driving chronic inflammation that extends to the central nervous system. \"Microbial translocation has long been viewed as a nonspecific consequence of gut barrier failure in critical illness, with downstream effects attributed primarily to the host immune response.\" This translocation of bacterial toxins activates systemic inflammatory circuits. \"Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits.\" \n\nTherapeutic strategies increasingly focus on repairing this barrier to mitigate neurodegeneration. Agents that stabilize the intestinal lining, such as plant-derived exosome-like nanoparticles, have shown potential. \"MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms.\" Similarly, metabolic signaling molecules can bridge the gut-brain gap: \"Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways.\" The integration of these pathways suggests that metabolic interventions can indeed improve neuro-metabolic outcomes by shielding the brain from peripheral inflammatory signals originating in the gut.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The gut-brain axis is now considered a key target for treating neuroinflammation; systemic inflammation originating in the intestine spreads to the brain, contributing to neurodegenerative disorders.\n* \"Truly\" degraders represent a novel class of dual-mechanism molecules that engage both ubiquitin-independent and ubiquitin-dependent degradation pathways to eliminate disease-relevant proteins.\n* In situ dextran synthesis by lactic acid bacteria is an emerging biothickening strategy used to improve the texture of non-dairy yogurt alternatives while considering clean-label functional food trends.\n* High-protein yogurt can drive distinct microbiome shifts in older adults, specifically increasing the abundance of *Coprococcus*, potentially conferring gut health benefits.\n* Certain natural compounds, such as rhubab (RR), restore intestinal barrier function while reprogramming the IDO-1-dependent TRP-KYN metabolic pathway to attenuate neuroinflammation.\n* Fermentation of ginseng by specific probiotics enriches protopanaxadiol (PPD)-type ginsenosides, which can seal the gut and reset redox homeostasis for precision geroprotection.\n* The \"bifid shunt\" facilitated by *Bifidobacterium* dominance is a key contributor to flavor enhancement in fermented plant-based products.\n* The PI3K/Akt pathway acts as a functionally necessary mediator of neuroprotection for natural alkaloids against cerebral ischemia/reperfusion injury.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n\n1.

By utilizing plant-derived agents such as Magnolia biondii-derived exosome-like nanoparticles (MFELNs) or microbial-biotransformed ginsenosides (PPD), researchers have demonstrated effective suppression of neuroinflammatory signaling in the hippocampus and peripheral immune cells, thereby providing a viable strategy to manage neurodegenerative trajectories through the microbiota-gut-brain axis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the gastrointestinal barrier acts as a fundamental defense against systemic inflammation. As evidenced in the literature, barrier dysfunction leads to the translocation of endotoxins such as LPS, which serves as a potent trigger for the NLRP3 inflammasome and subsequent neuroinflammatory responses. Emerging evidence highlights that MFELNs, derived from *Magnolia biondii*, effectively mitigate colitis by suppressing inflammatory signaling and restoring intestinal barrier proteins. Similarly, the fermentation of ginseng to enrich protopanaxadiol (PPD) transforms it into a potent anti-aging agent that seals the gut and resets redox homeostasis. These agents function by modulating the gut-brain-liver axis, effectively acting as \"molecular bridges\" that prevent the chronic, low-grade systemic inflammation (inflammaging) associated with neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived exosome-like nanoparticles (PELNs) possess a phospholipid bilayer structurally homologous to mammalian cells, enhancing their bioavailability for drug delivery.\n* The gut microbiota serves as an active metabolic site for transforming herbal precursors (e.g., ginsenosides) into active, bioavailable neuroprotective agents.\n* Systemic inflammation in conditions like rheumatoid arthritis is directly linked to the entry of intestine-derived LPS into the bloodstream, establishing a clear gut-joint-brain connection.\n* Chronic fatigue syndrome and obesity-related anxiety share common mechanisms rooted in gut dysbiosis and HPA-axis hyperactivity.\n* Short-chain fatty acids (SCFAs) function as critical mediators in the microbiota-gut-brain axis by preserving blood-brain barrier integrity and modulating glial cell states.\n* The gut-liver axis acts as a key filter; when this filter fails, bile acid metabolism is disrupted, further exacerbating neuroinflammation.\n* Prebiotic interventions can restore the firmicutes/bacteroidota ratio, directly correlating with improved cognitive outcomes.\n* Microbial metabolites from fermentable fibers are essential for suppressing histone deacetylase-mediated neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This review examines emerging evidence that the gut microbiome plays a more active and specific role in this process than previously appreciated. Dysbiosis during critical illness directly contributes to barrier dysfunction through depletion of metabolites that sustain epithelial integrity. Culture-independent approaches have revealed that gut-derived organisms are a major reservoir for secondary infection, with translocation governed by microbial virulence, community dynamics, and immune cell-mediated transport rather than barrier permeability alone. In parallel, organism-specific microbial components - including structurally diverse forms of lipopolysaccharide and bacterial DNA detected across multiple blood fractions - enter the circulation and differentially modulate host immune responses. Recent studies link circulating microbial DNA composition to distinct inflammatory phenotypes in sepsis and acute respiratory distress syndrome, suggesting these signals contribute to clinical heterogeneity. These findings support a revised framework in which translocation reflects the composition of the dysbiotic gut, not barrier integrity alone. Integrating microbial data with host phenotyping may enable more precise risk stratification and microbiome-informed therapeutic strategies in critical illness."

Residual inflammation is strongly associated with an increased risk of cardiovascular disease, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, cancer, and neurocognitive impairment. This review summarizes the current evidence on the microbiology-oriented mechanisms that sustain this state. We first outline a multifactorial network in which incomplete repair of intestinal mucosal damage, dysbiosis, reduced short-chain fatty acid production, and disturbed bile acid metabolism generate a patchy \"leaky gut.\" Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits. These inputs interact with intermittent HIV antigen expression from latent reservoirs, inflammatory cell death, chronic coinfections, lymphoid tissue fibrosis, mitochondrial dysfunction, and traditional lifestyle-related risk factors. Together, they establish a self-reinforcing gut-liver-immune axis that maintains low-grade inflammation and a procoagulant milieu under viral suppression. We then link these mechanisms to organ-specific complications and review the intervention data, focusing on early ART initiation, statin therapy, and cotrimoxazole prophylaxis as a proof-of-concept that modifying inflammatory and mucosal pressures can improve outcomes. Finally, we highlight research priorities and argue that the effective prevention of long-term complications in virally suppressed PLWH requires combination strategies targeting multiple nodes of this network, with particular attention to gut barrier repair and microbiome modulation."

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

Although peripheral determinants of barrier dysfunction have been studied, the contribution of central regulatory mechanisms remains unclear. \u03b2-Hydroxybutyrate (BHB), a major ketone body elevated during fasting, exhibits anti-inflammatory and barrier-protective effects peripherally, but its central actions are unknown. Here, we investigated whether BHB acts within the brain to regulate intestinal barrier function and visceral sensitivity using an LPS-induced rat model. Intracisternal BHB dose-dependently attenuated LPS-induced colonic hyperpermeability and visceral hypersensitivity, whereas an equivalent subcutaneous dose was ineffective, indicating a centrally mediated effect. The protection conferred by intracisternal BHB was abolished by vagotomy and by pharmacological inhibition of brain AMPK, orexin 1 receptors, histamine H1 receptors, basal forebrain cholinergic neurons (BFCNs), or adenosine A2B receptors. Peripheral BHB also ameliorated barrier dysfunction and visceral hypersensitivity; however, these effects persisted after vagotomy while remaining sensitive to central pharmacological blockade, suggesting engagement of shared brain signaling modules together with vagus-nonobligatory components. Collectively, these findings demonstrate that BHB regulates intestinal barrier function and visceral sensitivity through both central and peripheral mechanisms. Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways. BHB thus emerges as a neuro-metabolic signal modulating core gut-brain interaction processes and represents a promising therapeutic target for leaky gut-associated disorders, particularly IBS."

Rhubarb (RR) is widely applied to treat IS in the clinic. However, its underlying pharmacological mechanisms remain incompletely elucidated. To dissect the mechanism and pharmacological basis of RR's ability to ameliorate IS from the side of modulating tryptophan-kynurenine (TRP-KYN) metabolism and neuroinflammation. An embolic middle cerebral artery occlusion (MCAO) model was employed in rats to simulate human IS. Neurological deficit scores, hematoxylin-eosin, 2,3,5-triphenyltetrazolium chloride, alcian blue-periodic acid-Schiff staining, Western blotting, targeted metabolomics, immunofluorescence, and enzyme-linked immunosorbent assay were utilized to evaluate the efficacy of RR against cerebral ischemic injury, gut permeability, TRP-KYN metabolism levels, and neuroinflammation. Surface plasmon resonance and cell-based assays were further utilized to screen and validate potential bioactive ingredients of RR for the treatment of IS. In addition to mitigating cerebral ischemic damage, RR treatment substantially restored intestinal barrier function in IS rats by reducing leaky gut biomarkers, ameliorating histopathological alterations, and upregulating colonic tight junction proteins. Moreover, RR modulated TRP-KYN metabolism, concomitant with regulated expression and enzymatic activity of indoleamine 2,3-dioxygenase 1 (IDO-1) and the triggering receptor expressed on myeloid cells-1 (TREM-1) levels in both colon tissue and serum. Within the central nervous system, RR attenuated neuroinflammation triggered by MCAO through orchestrating microglial polarization and cytokine levels, accompanied by suppression of the TREM-1-mediated inflammatory signaling cascade. Chrysophanol 8-O-\u03b2-d-glucoside, rutinum, lindleyin, and (-)-catechin gallate from RR were identified as potential IDO-1 inhibitors, while rhein, lindleyin, methyl gallate, and chrysophanol 8-O-\u03b2-d-glucoside were identified as potential TREM-1 inhibitors, capable of attenuating the overexpression of IDO-1 and TREM-1 or TREM-1 and NOD-like receptor protein 3 (NLRP3). This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation. These effects are attributed to its bioactive components, including rutinum, chrysophanol 8-O-\u03b2-d-glucoside, lindleyin, (-)-catechin gallate, rhein, and methyl gallate."

Ubiquitination modification is implicated in the pathogenesis of cardiovascular diseases through diverse biological processes. However, the role of TRIM9, an E3 ubiquitin ligase, in AD remains unexplored. In this study, the expression profiles of TRIM9 and SMAD4 were analyzed using clinical samples, as well as Angiotensin II (Ang II)-induced mouse and human aortic endothelial cell (HAEC) models. Endothelial barrier function in AD was assessed through CCK-8 assays, vascular permeability measurements, immunofluorescence staining, hematoxylin-eosin and Verhoeff's van Gieson staining, and Western blot analysis. The underlying molecular mechanisms were elucidated using quantitative real-time PCR, immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and enzyme-linked immunosorbent assay (ELISA). TRIM9 was markedly overexpressed, whereas SMAD4 was significantly downregulated in AD. Knockdown of TRIM9 attenuated endothelial permeability, preserved the endothelial barrier integrity, and inhibited pyroptosis both in vivo and in vitro. Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression. Collectively, these findings demonstrate that elevated TRIM9 expression aggravates AD progression through SMAD4 destabilization, offering novel therapeutic insights for AD management."

Stilbamidine (SDC), a compound identified in Malaysian Kelulut honey (KH), has been reported to exhibit favourable binding affinity towards ACE2. This study aims to determine the effects of KH and SDC on the binding of spike protein to the ACE2 receptor, as well as to assess their modulatory potential on ACE2 gene and protein expression in lung and kidney cells. KH, SDC, and MLN 4760 (ACE2 inhibitor) were tested using an in vitro spike S1:ACE2 inhibition assay.

Although irritable bowel syndrome (IBS) is considered a disorder of gut-brain interaction, the role of UA in IBS remains unclear. An experimental rat model of IBS was induced using laser-induced shock waves (LISW) applied to the head. Hyperuricemia (HUA) was induced by intraperitoneal administration of inosine monophosphate and potassium oxonate. Visceral hypersensitivity was assessed by colorectal distension. Ileal mucosal permeability was measured using the Evans blue method. CRFR1 mRNA expression in the rectum, IL-10 and TGF-\u03b21 expression in the ileum, and IL-1\u03b1, IL-1\u03b2, and TNF expression in the medial prefrontal cortex (mPFC) and paraventricular nucleus (PVN) were quantified by qRT-PCR. Vagal involvement was assessed using subdiaphragmatic vagotomy or atropine treatment. LISW increased visceral hypersensitivity, ileal mucosal permeability, and rectal CRFR1 expression and reduced IL-10 expression in the ileum. HUA significantly ameliorated these changes. HUA was also associated with reduced IL-1\u03b2 expression in the mPFC and reduced IL-1\u03b1 and IL-1\u03b2 expression in the PVN in LISW-treated animals. Importantly, the ameliorative effects of HUA on visceral hypersensitivity were abolished by vagotomy or atropine treatment. Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain. The loss of HUA-induced suppression of visceral hypersensitivity after vagotomy or atropine treatment suggests the possible involvement of vagal and cholinergic brain-gut communication. Irritable bowel syndrome (IBS) is a common disorder in which people experience abdominal pain and bowel problems, often worsened by stress. We examined whether uric acid, a major endogenous antioxidant in the human body, can protect against changes seen in a rat model of IBS. An experimental model of IBS was created by applying laser\u2010induced shock waves to the head, leading to increased sensitivity to colorectal distension (a measure of visceral hypersensitivity), impaired barrier function of the lower small intestine, and reduced a protective anti\u2010inflammatory signal (IL\u201010) in the gut. Increasing blood uric acid levels reduced visceral hypersensitivity, improved the barrier function of the lower small intestine, and restored IL\u201010 levels. Importantly, the uric acid\u2013induced suppression of visceral hypersensitivity was lost when vagus nerve signaling was disrupted, indicating that vagal and cholinergic signaling is involved in this effect."

However, the adoption of plant-based alternatives depends on multiple factors, including consumer preferences, sensory quality, product affordability, and availability, in addition to sustainability and ethical considerations. Although nondairy yogurt alternatives may offer environmental advantages over conventional dairy products, their broader adoption is often constrained by textural limitations, which remain a major barrier to consumer acceptance. Addressing texture deficiencies requires strategic ingredient selection and optimized processing techniques. While existing literature focuses primarily on plant-based systems, alternative protein sources such as fungal proteins remain underexplored, with few studies evaluating fungal protein-based yogurt analogues. This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy. Compared with many heteropolysaccharides often produced at relatively low yields by yogurt starters, dextran, a homopolysaccharide, can be synthesized at higher levels by certain lactic acid bacteria (LAB) and contributes to enhanced viscosity and gel formation in plant-based matrices. We discuss the mechanisms underlying these effects, including dextran-protein interactions and water-binding capacity, as well as their relevance to clean-label and functional food trends. Key research priorities include identifying food-grade, high-yield dextran-producing LAB strains, assessing their safety and allergenicity, and investigating the digestive fate and health effects of in situ-produced dextrans. Overall, in situ dextran production represents a promising strategy for improving the texture and consumer acceptance of nondairy yogurt alternatives."

Here, untargeted GC-MS metabolomics was used to investigate the effects of standardized Brazilian green propolis on the striatal metabolic profile in the 6-hydroxydopamine (6-OHDA) rat model. Discriminant metabolites, including suberic acid, gluconic acid, heptadecane, and tartaric acid, distinguished experimental groups, capturing key features of the metabolic response to dopaminergic injury and treatment. Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways. Propolis treatment attenuated the elevation of suberic acid, accompanied by a reduction in gluconic acid levels, suggesting a metabolic profile linked to pathways involved in redox balance and glucose handling. Given previous reports identifying heptadecane as a hydrocarbon constituent of volatile propolis fractions, complementary GC-Q-TOF analyses demonstrated that heptadecane was absent from the administered extract, despite its consistent association with propolis-treated groups. Metabolic changes were accompanied by attenuation of nigrostriatal dopaminergic neurodegeneration and improved motor performance. Together, these findings delineate a striatal metabolic signature associated with Brazilian green propolis and identify suberic acid as a key metabolite linked to neuroprotection in experimental Parkinsonism."

The optimal preparation process of HPSCH was investigated by using schisandrin content and total extractive yield as indices. After one week of adaptive feeding, C57BL/6 mice were assigned to a normal control group, while the remaining mice were fed an HFD for eight weeks to establish the NAFLD mouse model. After being successfully modeled, the mice were divided into a blank control group, blank administration group, simple model group, fenofibrate group, SCH group, and HPSCH group. All groups were administered by intragastric administration for four weeks. Body weight changes of mice were recorded, and liver indices were calculated. The levels of blood lipid and liver function index in the serum of mice were measured. Hepatic histopathological changes were observed by using hematoxylin-eosin(HE) staining and oil red O staining. Mice's feces were collected, and the 16S rDNA high-throughput sequencing method was employed to analyze changes in the gut microbiota of mice. Untargeted lipidomic analysis of the liver was conducted by using liquid chromatography-mass spectrometry(LC-MS), and principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were adopted to screen and identify differential metabolites. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to perform relevant pathway analysis. Integrated analyses of gut microbiota and differential metabolites were performed to compare the similarities and differences in efficacy of HPSCH and SCH. The results show that both the HPSCH group and SCH group exert similar effects on biochemical indices in serum and hepatic pathological changes, lipid metabolism can be regulated, and liver injury in NAFLD mice can be improved. The two groups show similar changes in microbial abundance, trending toward the blank control group and maintaining intestinal homeostasis. Compared with those of the simple model group, the differential metabolites and metabolic pathways of both the HPSCH group and SCH group show similarity, and the differential metabolites are mainly triglycerides, diglycerides, phosphatidylcholines, phosphatidylglycerols, and so on. Metabolic pathways include glycerophospholipid metabolism, choline metabolism, retrograde endocannabinoid signaling, thermogenic lipolysis, and so on. This indicates that HPSCH and SCH share common advantages in improving hepatic function in mice and achieve comparable effects. HPSCH can improve blood lipid and liver function indices in NAFLD mice, attaining the therapeutic effect through the regulation of gut microbiota and lipid metabolism. Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application. Moreover, the application of HPSCH may contribute to the conservation of medicinal resources."

A total of 34 active ingredients of Scutellariae Radix were screened from the TCMSP database, and 65 potential therapeutic targets were identified by combining SwissTargetPrediction and GEO data analysis. Protein-protein interaction(PPI) network construction, molecular docking, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses indicated that Scutellariae Radix might exert the anti-AS effect by modulating inflammatory responses, negatively regulating pyroptosis, and influencing the NOD-like receptor(NLRP) signaling pathway.

While dysregulated metabolism has long been noted in DS, the underlying cause is poorly understood and vastly understudied. To fill this critical knowledge gap, we conducted a comprehensive metabolic analysis of Dp(16)1Yey/+mice (abbreviated Dp16), a segmental duplication model carrying ~58% of the triplicated Hsa21 gene orthologs. Our multi-tissue transcriptomic analyses reveal shared and sex-specific increases in expression dosage of the triplicated genes in white and brown adipose tissues, liver, skeletal muscle, and hypothalamus. Despite sexual dimorphism in body weight, body temperature, food intake, and physical activity, Dp16 males and females share striking core phenotypes of pronounced insulin resistance, glucose intolerance, impaired lipid clearance, and dyslipidemia. Functional assessments, combined with biochemical, transcriptomic, and metabolomic analyses reveal tissue signatures of immune activation and a pro-inflammatory state, ER and oxidative stress, fibrosis, impaired glucose and fatty acid catabolism, altered lipid and bile acid profiles, and reduced mitochondrial respiratory capacity in Dp16 mice. These concerted changes disrupt homeostatic mechanisms that underpin metabolic health, contributing to systemic metabolic dysfunction. An obesogenic diet further exacerbates insulin resistance in Dp16 males and females despite divergent weight gain. The collective phenotypes broadly reflect the metabolic profile of DS. Our extensive molecular, biochemical, and physiological data provide an essential foundation for genetic dissection of dosage-sensitive genes affecting glucose and lipid metabolism, and for testing therapeutic strategies to improve metabolic outcomes in DS."

Increasing evidence supports the view of HFpEF as a systemic inflammatory syndrome driven by aging and cardiometabolic comorbidities, including obesity, hypertension, and chronic kidney disease. Within this framework, regulatory T cells (Tregs), which are essential for maintaining immune tolerance and limiting excessive inflammation, have emerged as important modulators of disease progression. However, the mechanisms underlying Treg dysfunction in HFpEF have remained poorly understood. In this issue, Srinivas et al. identify stromal interaction molecule 1 (STIM1)-dependent calcium signaling as a critical regulator of Treg instability in HFpEF. The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways. Using a cardiometabolic murine model and Treg-specific STIM1 knockout mice, they establish a causal role for Treg-intrinsic STIM1 signaling in disease development. These findings position STIM1 as a molecular link between cardiometabolic stress, immune dysregulation, and cardiac remodeling. They further support the concept that immune-cell plasticity is a major determinant of HFpEF pathogenesis and suggest that preserving Treg stability may represent a novel therapeutic strategy. Although important questions remain regarding disease timing, clinical translation, and sex-specific effects, this work advances our understanding of HFpEF as an immune-mediated disorder and identifies STIM1-dependent calcium signaling as a promising therapeutic target."

We previously introduced ByeTACs, bifunctional molecules that directly recruit proteins to the proteasome for E-ligase independent degradation. Here, we report \"Truly\" degraders, a new class of dual-mechanism molecules that combine a ligand for the proteasomal receptor Rpn13 with a ligand for cereblon (CRBN) to simultaneously engage both ubiquitin-independent and ubiquitin-dependent degradation pathways. Structure-guided design identified an optimal linker length that supports efficient substrate processing, with the PEG4 derivative (Truly-4) inducing robust depletion of both Rpn13 and CRBN in several cancer cell types. Remarkably, Truly-4 is the first noncovalent small molecule shown to degrade full-length Rpn13, a target previously approached using covalent or domain-restricted strategies. Mechanistic studies confirmed that degradation of Rpn13 proceeds via CRBN-dependent E3 ligase activity, whereas CRBN degradation occurs through an E-ligase independent process, consistent with a ByeTAC mechanism. Importantly, Truly-4 induces selective cytotoxicity in hematologic and solid cancer cell lines but not in healthy cells, despite comparable Rpn13 depletion, indicating that dual degradation can uncouple target engagement from toxicity. These findings establish a generalizable framework for engineering bifunctional degraders that program the proteasome to execute parallel degradation mechanisms and highlight proteasome receptors as druggable nodes for selective destruction of disease-relevant proteins."

Yet the oversimplified concept of 'leaky gut' as a singular phenomenon has limited both mechanistic understanding and therapeutic development. It is now recognized that intestinal permeability occurs via two molecularly distinct, differentially regulated trans-tight junction pathways, while a tight junction-independent unrestricted pathway allows flux at sites of epithelial damage. The pore pathway is a high-conductance, size-selective and charge-selective flux route that mediates ion and water flux. Its upregulation can be either protective, as in infectious enterocolitis, or pathogenic, as in immune-mediated disease or, as shown recently, in sepsis. Myosin light chain kinase activation enhances flux across the leak pathway, a low-conductance macromolecular flux route, that promotes progression of immune-mediated diseases. Recently developed molecularly targeted, pathway-specific approaches to barrier restoration are effective and can outperform current therapies without the complications of broad immunosuppression. The evolving pathway-resolved framework transforms intestinal barrier biology from a descriptive science into mechanism-specific therapeutic approaches that have promise as independent agents and as complements to available immune-targeted therapies."

Strength training (ST) combined with adequate protein intake is a key element in reversing and improving functional capacity. Protein, especially Whey Protein isolates (WPI), is widely used to improve muscle mass. In contrast, high-protein products, such as protein yogurt (PY), may offer similar benefits for muscle health and drive additional effects on gut health, which is altered in older adults. For this, we aim to compare WP and PY supplementation during ST on body composition, strength, and gut microbiome in untrained older adults.\u00a0Seventeen untrained adults (60-70 years) were randomized to either consume WP (25 g) or PY (24.5 g) along with an 8-week supervised ST program (3 sessions/week). Initial and final assessments included body composition (BIA), strength (10RM, isokinetic torque, handgrip), gait speed, resting metabolic rate, and gut microbiome (16 S rRNA sequencing). Data were analyzed using repeated-measures ANOVA and diversity metrics. Both groups increased skeletal muscle mass (WP: +0.47 kg; PY: +0.50 kg) and improved strength and gait speed (p\u2009<\u20090.01), with no between-group differences. Fat mass decreased only in WP (p\u2009=\u20090.02), while resting metabolic rate increased in PY (p\u2009=\u20090.03). Microbiome analysis revealed distinct shifts: WP increased the Firmicutes/Bacteroidota ratio and enriched Subdoligranulum, whereas PY enhanced alpha diversity and increased the abundance of Coprococcus. Functional pathway predictions indicated differential enrichment in metabolic and signaling processes. High-protein yogurt and whey protein similarly improve muscle mass, strength, and functional capacity during ST, while exerting distinct effects on gut microbiome composition. Yogurt represents a cost-effective alternative to whey protein and may confer additional gut health benefits.Trial registration: Clinicaltrials.gov identifier NCT06412302.

Despite their broad consumption, systematic comparisons of their biochemical characteristics remain limited. In this study, integrated untargeted and targeted metabolomics approaches were applied to compare the comprehensive metabolite profiles of PS and YG. PS exhibited relatively higher levels of amino acids, dicarboxylic acids, and lysophospholipids, along with short-chain fatty acids such as acetate and propionate, and amino acid-derived bioactive metabolites, including \u03b3-aminobutyric acid, branched-chain hydroxy acids, indole derivatives, and \u03b3-glutamylpeptides. In contrast, YG showed higher relative abundances of carbohydrates, acylcarnitines, sphingolipids, and bioactive metabolites such as butyrate, creatine, carnitine, and orotic acid. Based on these metabolomic differences, 27 PS-specific and 17 YG-specific marker metabolites were identified. To explore their functional relevance, in vitro antioxidant and antiglycation activities were evaluated. PS exhibited significantly higher antioxidant and antiglycation activities than YG, which were positively correlated with amino acids and indole derivatives. Indole-3-acrylic acid, indole-3-acetic acid, and indole-3-propionic acid showed antiglycation activity and were identified as PS-specific bioactive marker metabolites.

We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored.

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\"What is the core mechanism that Almased uses to improve metabolism and liver function and can the mechanism be repurposed as a therapeutic in neurodegenerative disease via the gut-brain axis?\"\n\nThe provided literature contains no mention of the product \"Almased.\" Consequently, no core mechanism for this specific agent can be established, nor can its efficacy in metabolic or liver function be evaluated using the context. However, the provided literature extensively documents gut-brain axis mechanisms\u2014such as the modulation of intestinal permeability, the suppression of proinflammatory signaling, and the activation of metabolic pathways like the PI3K/Akt/Nrf2 or AMPK-orexin axis\u2014that are currently being repurposed as therapeutic targets in neurodegenerative diseases.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe claim concerning \"Almased\" is unsubstantiated by the provided literature. The investigation focuses on whether metabolic modulators identified in the text (e.g., bioactive plant extracts, metabolites like \u03b2-hydroxybutyrate, or specific fermentation products) can be repurposed as neuroprotective agents via the restoration of intestinal barrier integrity and modulation of gut-brain signaling, a valid scientific inquiry supported by the text.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent research suggests that systemic metabolic health is fundamentally coupled to gut barrier integrity. Pathological increases in intestinal permeability, often termed \"leaky gut,\" allow microbial products to enter systemic circulation, driving chronic inflammation that extends to the central nervous system. \"Microbial translocation has long been viewed as a nonspecific consequence of gut barrier failure in critical illness, with downstream effects attributed primarily to the host immune response.\" This translocation of bacterial toxins activates systemic inflammatory circuits. \"Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits.\" \n\nTherapeutic strategies increasingly focus on repairing this barrier to mitigate neurodegeneration. Agents that stabilize the intestinal lining, such as plant-derived exosome-like nanoparticles, have shown potential. \"MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms.\" Similarly, metabolic signaling molecules can bridge the gut-brain gap: \"Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways.\" The integration of these pathways suggests that metabolic interventions can indeed improve neuro-metabolic outcomes by shielding the brain from peripheral inflammatory signals originating in the gut.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The gut-brain axis is now considered a key target for treating neuroinflammation; systemic inflammation originating in the intestine spreads to the brain, contributing to neurodegenerative disorders.\n* \"Truly\" degraders represent a novel class of dual-mechanism molecules that engage both ubiquitin-independent and ubiquitin-dependent degradation pathways to eliminate disease-relevant proteins.\n* In situ dextran synthesis by lactic acid bacteria is an emerging biothickening strategy used to improve the texture of non-dairy yogurt alternatives while considering clean-label functional food trends.\n* High-protein yogurt can drive distinct microbiome shifts in older adults, specifically increasing the abundance of *Coprococcus*, potentially conferring gut health benefits.\n* Certain natural compounds, such as rhubab (RR), restore intestinal barrier function while reprogramming the IDO-1-dependent TRP-KYN metabolic pathway to attenuate neuroinflammation.\n* Fermentation of ginseng by specific probiotics enriches protopanaxadiol (PPD)-type ginsenosides, which can seal the gut and reset redox homeostasis for precision geroprotection.\n* The \"bifid shunt\" facilitated by *Bifidobacterium* dominance is a key contributor to flavor enhancement in fermented plant-based products.\n* The PI3K/Akt pathway acts as a functionally necessary mediator of neuroprotection for natural alkaloids against cerebral ischemia/reperfusion injury.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n\n1.

This review synthesizes recent advances in microbial biosynthesis and engineering strategies for producing high-quality GABA-frozen yogurt, including lactic acid bacteria strain selection (e.g., Levilactobacillus brevis, Lactiplantibacillus plantarum), fermentation optimization, and critical processing steps such as homogenization, aging, and dynamic freezing. Advanced technologies, including high-pressure processing, microfluidization, and the use of cryoprotectants, are discussed in relation to achieving target physicochemical properties. Target physicochemical properties for frozen yogurt systems typically include 35%-40% (w/w) total solids in the frozen yogurt mix and 20%-50% (v/v) overrun in the final frozen product, consistent with ranged reported for frozen yogurt and adjacent frozen dairy desserts; these values depend on formulation composition and processing conditions. Previous clinical trials and limited human studies suggest that GABA may contribute to anxiolytic and neuroprotective effects via the gut-brain axis; however, evidence specific to dairy-based delivery systems remains limited. Key challenges include maintaining GABA stability during frozen storage, scaling production, and navigating regulatory frameworks. Future perspectives highlight nanoencapsulation, synbiotic formulations, and computational modeling as tools to advance the development of GABA-enriched frozen yogurt as a functional dairy product supporting cognitive wellness.\n\nID: 42436037\nTitle: Beyond dairy: The science, sustainability, and future of non-dairy yogurt alternatives.\nAbstract: Driven by rising consumer demand for sustainable alternative protein sources as viable replacements for conventional animal-based proteins in human diets, the non-dairy yogurt market has experienced significant global growth. This chapter comprehensively examines the scientific principles, sustainability implications, and future trends of these alternatives. Scientifically, the primary challenge lies in forming firm gel structures and desirable flavor compounds by fermenting non-dairy substrates which lack the inherent composition and structure of bovine milk. The possible strategies to address the two hurdles faced by the non-dairy yogurt industry are discussed, including a comparison of their respective merits and limits. The sustainability assessment is conducted from four aspects-nutrition, economy, society, and environment, alongside an analysis of health implications. The future trends of non-dairy yogurt alternatives, including the utilization of novel protein substrates (e.g., microbial protein and microalgae), assistance of artificial intelligence and novel biotechnology, and the development of personalized products with targeted nutritional profiles are discussed. With significant scientific breakthroughs emerging, non-dairy yogurts, in our opinion, are positioned to do more than compete with dairy. They are set to redefine consumers' expectations of yogurt entirely.\n\nID: 42402312\nTitle: The Effectiveness of Milk Fermentation in Escherichia coli and Staphylococcus aureus Inactivation During Yogurt Processing and Storage: A Systematic Review and Meta-Analysis.\nAbstract: Fermentation is widely used to control microbial growth in food, thereby improving microbial safety and extending shelf life. Studies have reported contradictory results regarding the efficiency of milk fermentation in microbial inactivation. Therefore, this meta-analysis aimed to evaluate the effect of fermentation on the inactivation of E. coli and S. aureus during yogurt processing and storage. The analysis was performed on 46 studies and 81 effect sizes, selected in accordance with PRISMA guidelines. Data were analyzed using Random and Mixed-Effects Models fitted with the REML estimator in the R environment using metafor. Results showed that yogurt storage exhibited the highest E. coli and S. aureus inactivation (4.66 log CFU/mL) compared to yogurt processing (1.68 log CFU/mL). Over 50% of the studies exhibited high pathogen reduction, with an interquartile range of 91.12 to 99.93% (median\u00a0=\u00a098.74%) and 99.89 to 100% (median\u00a0=\u00a0100%) during fermentation and storage, respectively. E. coli and S. aureus had higher reductions of 4.41 and 4.96 log CFU/mL during storage, respectively. Meta-regression showed that mesophilic and thermophilic temperatures and milk fermentation in the 0-12\u00a0h category had significantly higher S. aureus reduction (p\u00a0<\u00a00.05). Storage of milk for 37-48\u00a0h showed a greater E. coli reduction. Large inoculum size of over 6 log CFU/mL and the region Europe significantly influenced pathogen reduction. The results showed that a combination of milk fermentation and storage can eliminate E. coli and S. aureus, contributing to the safety of yogurt.\n\nID: 42377118\nTitle: Short-term responsiveness of DNA methylation-based aging biomarkers to a multimodal intervention comprising exercise and dietary guidance involving daily consumption of yogurt containing Bifidobacterium longum BB536: an exploratory randomized controlled trial.\nAbstract: Aging-related chronic diseases are driven by multiple mechanisms, motivating efforts to develop feasible interventions that can attenuate biological aging. DNA methylation-based epigenetic clocks, particularly measures of the pace of aging such as DunedinPACE, are sensitive to relatively short-term changes in aging processes. However, evidence from randomized controlled trials remains limited. We conducted a randomized controlled trial to test a 12-week multimodal lifestyle intervention comprising exercise and dietary guidance involving daily consumption of yogurt containing Bifidobacterium longum BB536 on DNA methylation-based aging measures in overweight men aged \u226550 years. The intervention group exhibited a significant deceleration in DunedinPACE, corresponding to an estimated 2.2% slower pace of aging, whereas no meaningful change was observed in the control group. Exploratory analyses further identified a significant reduction in DNAmCystatinC, a renal-related GrimAge surrogate marker, while no clock within the biological age remained significant after false discovery rate correction. These findings suggest that a feasible, multimodal lifestyle intervention-including exercise and dietary guidance with daily consumption of yogurt containing Bifidobacterium longum BB536-may be associated with short-term changes in selected DNA methylation-based aging measures. Larger and longer-term studies are warranted to confirm the durability and clinical relevance. This clinical trial was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000057293).\n\nID: 42316775\nTitle: Structural Modification of Milk Proteins During Yogurt Processing: Effects on Protein Digestion and Absorption.\nAbstract: Yogurt is a popular functional dairy product prized for health benefits and nutritional value, especially as a significant source of high-quality proteins. In recent years, the research on the processing-induced modification of milk protein structure to regulate its nutritional properties has attracted much attention. Although yogurt processing has been extensively studied at the physicochemical level, novel processing technologies continue to emerge. At the same time, increasing attention has been directed toward digestion-driven nutritional functionality, calling for a renewed, digestion-oriented interpretation of processing-induced protein modifications and their downstream physiological relevance. The review synthesizes current knowledge on how key yogurt processing technologies-standardization, homogenization, heat treatment, and fermentation-govern milk protein structural transformations, gel network formation, and bioactive peptide generation. Particular emphasis is placed on linking processing-induced protein changes with gastrointestinal digestion behaviors, including gastric emptying, enzymatic hydrolysis, and nutrient absorption. Precisely, processing-driven protein denaturation, aggregation, redistribution, and hydrolysis collectively determine yogurt matrix architecture and its digestive fate. Structural features of the yogurt matrix modulate gastric emptying kinetics, whereas protein conformational changes influence enzymatic accessibility and hydrolysis rates. Fermentation-associated proteolysis further alters the profile and availability of absorbable peptides and amino acids. This review may help for advancing yogurt production from standardized processing toward precision nutrition design and for developing functional yogurts with targeted digestive and health benefits.\n\nID: 42300034\nTitle: Microbiota dynamics and their impact on the metabolite in lupin oat yoghurt analogues.\nAbstract: The growing demand for nutritious, flavour-rich plant-based yoghurt analogues calls for innovative fermentation strategies. This study examined the impact of three probiotic combinations-Y1 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus rhamnosus), Y2 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus paracasei) and Y3 (Lactobacillus plantarum and Bifidobacterium sps.)- on microbial dynamics and metabolite formation in lupin-oat yoghurt analogues, using unfermented milk analogues as a control. Samples were assessed during fermentation and throughout 28 days of refrigerated storage (4 \u00b0C) using microbial enumeration, 16S rRNA sequencing, acidification profiling, and mass spectroscopy-based metabolomics. Fermentation increased volatile compounds, from 23 in the control to 28 (Y1), 41 (Y2) and 54 (Y3). Probiotic combination Y3 exhibited the most complex and stable aroma profile, enriched in pleasant volatiles such as butanoic acid, phenylacetaldehyde, and butyl esters which effectively masked off-flavours like hexanal and heptanal. Microbiota analysis revealed stable formulation-specific communities, with- Streptococcus dominating in yoghurt analogues Y1 and Y2, and Bifidobacterium prevailing in yoghurt analogues Y3. KEGG-based functional prediction linked these transformations to microbial enzymatic activities within metabolic pathways. Notably, Bifidobacterium dominance in Y3 facilitated enhanced ester biosynthesis and conversion of aldehydes to acids, highlighting the \"bifid shunt\" as a key contributor to flavour enhancement. This integrated multi-omics approach highlights the critical role of targeted probiotic selection in modulating fermentation biochemistry, microbial ecology, and sensory attributes in plant-based lupin-oat yoghurt analogues. Notably, Bifidobacterium-driven fermentation in Y3 offers a promising strategy for improving the flavour profile and consumer acceptance of lupin-oat yoghurt analogues.\n\nID: 42263786\nTitle: Production of exopolysaccharides from Lactobacillus species and optimization of physiochemical parameters by response surface methodology.\nAbstract: Exopolysaccharides (EPS) are high molecular weight carbohydrate polymers secreted by microorganisms. The aim of the study was to isolate Lactobacillus strains that produce EPS from dairy sources and to enhance EPS production. The dairy source milk, yogurt, and cheese were collected from the local market for isolation of EPS producing strain. The maximum EPS-producing strain was further identified based on biochemical, morphological, and 16S RNA sequencing. Whey was used as a substrate due to its low cost and nutrient- rich composition. Different organic and inorganic nitrogen sources were screened. Central Composite Design (CCD) of Response Surface Methodology (RSM) was used for the optimization of physiochemical parameters. Five various physio-chemical parameters i.e. pH, temperature, nitrogen source, substrate concentration, and incubation period, were optimised. The process was subsequently upscaled in a 1.5\u00a0L lab scale bioreactor. Among these, the isolate obtained from cheese exhibited the highest EPS yield. The isolated strain was identified as Limosilactobacillus fermentum-CP158463.1. The yeast extract was found to be the best source of nitrogen 1.7\u00a0\u00b1\u00a00.15\u00a0mg/ml of EPS yield. The optimal conditions for maximum EPS (2.729\u00a0mg/mL) were observed at pH\u00a08, 40\u00a0\u00b0C, 1% nitrogen concentration, 20% substrate concentration, and a 48-h incubation time. The maximum yield (8.396\u00a0\u00b1\u00a01.73\u00a0mg/ml) was obtained at 200\u00a0rpm with 96\u00a0h incubation period. The study shows that Lactobacillus originating from dairy has the capacity to produce EPS, and the RSM model can be used for effective low-cost production.\n\nID: 42235223\nTitle: Influence of Caatinga honey floral origin on fermentation performance, chemical composition, and bioactive profile of mead.\nAbstract: Honeys from the Caatinga biome exhibit diverse composition, which may be a key determinant for mead quality and diversity. This investigates the influence of floral origin on the fermentation performance, chemical composition, and antioxidant properties of meads. Five honey samples, including monofloral and polyfloral types, were characterised via melissopalynological analysis and fermented in 3\u00a0L glass bioreactors using S. cerevisiae (4.5\u00a0\u00d7\u00a0105 cells/mL) at 20\u00a0\u00b0C for 24\u00a0days. Honey quality was assessed through physicochemical parameters, sugar profiles, and colour, while meads were analysed for phenolic compounds, sugars, organic acids, and alcohols using HPLC. Antioxidant activity was evaluated using DPPH, ABTS, and FRAP assays. Floral origin influenced fermentation kinetics, yeast viability, and the bioactive composition of meads. Monofloral M1 (jurema-preta) and M5 (mal\u00edcia) yielded meads with the highest phenolic and antioxidant potential, whereas M2 (polyfloral) achieved superior ethanol content. The findings paves the way for developing alcoholic beverages using Caatinga honeys.\n\nID: 42212401\nTitle: Texture Engineering of Nondairy Yogurt Alternatives: Ingredient Selection, Processing Strategies, and the Role of In Situ Dextrans.\nAbstract: A global shift from diets rich in animal-based products toward plant-based diets has been widely promoted as a key strategy for creating more sustainable food systems. However, the adoption of plant-based alternatives depends on multiple factors, including consumer preferences, sensory quality, product affordability, and availability, in addition to sustainability and ethical considerations. Although nondairy yogurt alternatives may offer environmental advantages over conventional dairy products, their broader adoption is often constrained by textural limitations, which remain a major barrier to consumer acceptance. Addressing texture deficiencies requires strategic ingredient selection and optimized processing techniques. While existing literature focuses primarily on plant-based systems, alternative protein sources such as fungal proteins remain underexplored, with few studies evaluating fungal protein-based yogurt analogues. This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy. Compared with many heteropolysaccharides often produced at relatively low yields by yogurt starters, dextran, a homopolysaccharide, can be synthesized at higher levels by certain lactic acid bacteria (LAB) and contributes to enhanced viscosity and gel formation in plant-based matrices. We discuss the mechanisms underlying these effects, including dextran-protein interactions and water-binding capacity, as well as their relevance to clean-label and functional food trends. Key research priorities include identifying food-grade, high-yield dextran-producing LAB strains, assessing their safety and allergenicity, and investigating the digestive fate and health effects of in situ-produced dextrans. Overall, in situ dextran production represents a promising strategy for improving the texture and consumer acceptance of nondairy yogurt alternatives.\n\nID: 42202715\nTitle: Temporal dynamics of the S. thermophilus phage population in a yogurt production facility.\nAbstract: Starter cultures are essential for milk fermentation, but phage infections can disrupt production, compromising product quality and causing economic losses. In this study, we investigated the dynamics, diversity, and persistence of 25 S. thermophilus phages isolated over a 15-year period from a large yogurt manufacturing plant. Phages were classified into Moineauvirus (16) and Brussowvirus (9), comprising ten distinct restriction profiles. Host range, genomic features, and resistance to thermal and chemical treatments were analyzed to identify factors underlying their long-term persistence. No significant differences in thermal resistance between the two groups were observed at 63\u00a0\u00b0C (30\u00a0min), 72\u00a0\u00b0C (5\u00a0min), or 90\u00a0\u00b0C (5\u00a0min). However, Brussowvirus phages exhibited greater stability during storage at 25\u00a0\u00b0C and 8\u00a0\u00b0C over eight months and tolerated sodium hypochlorite concentrations up to 500\u00a0ppm. All phages were effectively inactivated by 2.0% Lysoform\u2122, below the manufacturer's recommended concentration (2.8%). Most phages displayed at least one resistance trait, contributing to their persistence in industrial environments. Genomic analysis revealed double-stranded DNA genomes ranging from 33.2 to 39.8\u00a0kb, encoding 40-58 predicted ORFs. Several phages carried genes coding for anti-CRISPR proteins (AcrIIA3, AcrIIA5, AcrIIA6, AcrIIA21, AcrIIA25, and truncated AcrIIA36), enabling evasion of the main defense systems in S. thermophilus. Notably, infectivity was not always linked to Acr presence or protospacer matches, indicating alternative bacterial resistance mechanisms. These findings underscore the complexity of phage-host interactions and highlight the need for continuous monitoring and improved control strategies in dairy processing environments.\n\nID: 42184521\nTitle: Balancing the modulation of soy protein structure to achieve improved texture and reduced antigenicity in soy yogurt: A practical approach of proteolytic pretreatment and lactic acid bacteria fermentation.\nAbstract: Achieving multiple goals in complex food systems requires precise protein modification. Soy yogurt, a promising plant-based alternative, suffers from poor texture and allergenicity. Few studies have investigated strategies for this dual goal or the mechanisms involved. A two-step strategy combining proteolytic pretreatment with lactic acid bacteria fermentation was developed to address both issues. Soymilk was pretreated with papain, alkaline protease or Flavourzyme (100-1300\u00a0U/g) before fermentation. Flavourzyme pretreatment maximized hydrolysis efficiency and significantly softened soy yogurt texture. A critical hydrolysis threshold (\u223c17%) is identified for optimal texture, yielding reduced psizes (\u223c15\u00a0\u03bcm) and minimized syneresis (26.8%-29.7%). Antigenicity reduction depends on epitope specificity rather than hydrolysis degree. Flavourzyme pretreatment reduced antigenicity to 1.28% at 700\u00a0U/g (77%-96% degradation of major epitopes) and ultimately to 0.77% at 1300\u00a0U/g. Coordinating psize with targeted degradation of allergenic epitopes therefore offers a practical strategy for plant-based yogurt systems.\n\nID: 42151371\nTitle: Protein yogurt and whey protein produce comparable muscle gains, but divergent microbiome shifts during strength training in older adults.\nAbstract: Sarcopenia, the age-related decline in muscle mass and strength, affects the functional capacity of older adults. Strength training (ST) combined with adequate protein intake is a key element in reversing and improving functional capacity. Protein, especially Whey Protein isolates (WPI), is widely used to improve muscle mass. In contrast, high-protein products, such as protein yogurt (PY), may offer similar benefits for muscle health and drive additional effects on gut health, which is altered in older adults. For this, we aim to compare WP and PY supplementation during ST on body composition, strength, and gut microbiome in untrained older adults.\u00a0Seventeen untrained adults (60-70 years) were randomized to either consume WP (25 g) or PY (24.5 g) along with an 8-week supervised ST program (3 sessions/week). Initial and final assessments included body composition (BIA), strength (10RM, isokinetic torque, handgrip), gait speed, resting metabolic rate, and gut microbiome (16 S rRNA sequencing). Data were analyzed using repeated-measures ANOVA and diversity metrics. Both groups increased skeletal muscle mass (WP: +0.47 kg; PY: +0.50 kg) and improved strength and gait speed (p\u2009<\u20090.01), with no between-group differences. Fat mass decreased only in WP (p\u2009=\u20090.02), while resting metabolic rate increased in PY (p\u2009=\u20090.03). Microbiome analysis revealed distinct shifts: WP increased the Firmicutes/Bacteroidota ratio and enriched Subdoligranulum, whereas PY enhanced alpha diversity and increased the abundance of Coprococcus. Functional pathway predictions indicated differential enrichment in metabolic and signaling processes. High-protein yogurt and whey protein similarly improve muscle mass, strength, and functional capacity during ST, while exerting distinct effects on gut microbiome composition. Yogurt represents a cost-effective alternative to whey protein and may confer additional gut health benefits.Trial registration: Clinicaltrials.gov identifier NCT06412302. Date of registration 06/05/2024.\n\nID: 42134119\nTitle: Effects of oat \u03b2-glucans with different molecular weights on the physicochemical properties, fermentation kinetics, and in vitro digestibility characteristics of yogurt.\nAbstract: This study investigated the effects of oat \u03b2-glucan concentration and molecular weight (MW) on the properties, fermentation kinetics, and in vitro digestibility of set-style yogurt. A hedonic test was used for sensory evaluation, along with texture analysis, water holding capacity, pH, acidity, viscosity, MTT assay, and INFOGEST digestion model (SDS-PAGE, degree of hydrolysis). Optimal concentration was 1.0% (w/v). Three fractions-high (H-\u03b2G), medium (M-\u03b2G), and low (L-\u03b2G) MW-were prepared by acid hydrolysis. M-\u03b2G gave the best sensory attributes, while H-\u03b2G showed highest firmness and viscosity. H-\u03b2G did not impede acidification, whereas M-\u03b2G and L-\u03b2G initially slowed acidification but increased early starter metabolic activity. M-\u03b2G and L-\u03b2G promoted gastric protein hydrolysis (higher degree of hydrolysis, faster SDS-PAGE band disappearance), while H-\u03b2G mildly delayed proteolysis due to high viscosity. In conclusion, \u03b2-glucan addition influenced yogurt properties in an MW-dependent manner, 1.0% M-\u03b2G improved texture, sensory quality, and protein digestibility.\n\nID: 42134014\nTitle: Antibacterial activity and effect on the outer membrane permeability of Apis mellifera honey from Brazil.\nAbstract: This study evaluates the antibacterial activity of Apis mellifera honey (in fresh form and in extracted fractions) and its effects on the outer membrane permeability of Enterococcus faecalis and Staphylococcus epidermidis. Five honey samples from four municipalities in the Midwest of Brazil (Mato Grosso state) were evaluated in this study. Samples of fresh honey and its hexane, ethyl acetate, and n-butanol fractions were prepared by the fractional extraction method in a separating funnel using each fraction's solvent. Antibacterial activities were assessed using the broth microdilution method with serial dilution of the samples ranging from 1000 to 1.95\u03bcg/ml. Outer membrane permeability was determined by the broth microdilution method with a combination of honey or solvent extract fraction (80-0.15mg/ml) and clarithromycin and erythromycin (20-0.04\u03bcg/ml) prepared in a checkerboard. Time-kill assays were performed at 2, 4, 8 and 24h. At a concentration of 1000\u03bcg/ml, no antibacterial activity was observed, with inhibition below 24% for two bacteria. Honey 1 (80mg/ml) and its n-butanol fraction increased the outer membrane permeability of E. faecalis when combined with clarithromycin (20\u03bcg/ml), but no effect on membrane permeability of E. faecalis was observed for the remaining r four honey samples and their fractions. None of the samples affected the membrane permeability of S. epidermidis. We concluded that honey 1 increase the antibacterial activity of clarithromycin and erythromycin against E. faecalis, possibly due to the action of flavonoids.\n\nID: 42116490\nTitle: The antidiabetic potential of Leuconostoc mesenteroides strain SB1075 fermented soy yoghurt: Insights from mouse intestinal transcriptomics and metabolite analyses.\nAbstract: Fermented foods are recognised as functional due to their health-promoting bioactive metabolites. Our previous study showed enhanced shelf-life with stable functional metabolites of soy yoghurt fermented with Leuconostoc mesenteroides strain SB1075. Building on these findings, we prepared a new batch of SB1075-fermented soy yoghurt for animal experiments and evaluated its antidiabetic potential using transcriptomic and metabolomic approaches. GC-MS profiling confirmed reproducible metabolite patterns in fermented soy yoghurt, with the putative presence of bioactive compounds including D-pinitol and myo-inositol. Soy yoghurt was administered orally (as lyophilised powder) at the doses of 100, 200, and 400\u00a0mg/kg body weight to streptozotocin (STZ)-induced diabetic Swiss albino mice for 5\u00a0weeks, with unfermented soymilk as a control. The 100\u00a0mg/kg dose produced the most pronounced metabolic improvement, markedly reduced fasting blood glucose (90.75\u00a0\u00b1\u00a08.72 vs 421.5\u00a0\u00b1\u00a028.94\u00a0mg/dL in diabetic controls, p\u00a0\u2264\u00a00.001), improving glucose tolerance, and restoring lipid and liver biochemical parameters. Transcriptomic analysis of the intestinal tissue revealed upregulation of genes associated with insulin signalling and glucose metabolism genes (Insr, Irs1, Gck, & Pklr) alongside downregulation of inflammatory mediators (Il6 and Tnf). Metabolomic profiling further indicated differential abundance of several putatively annotated metabolites linked to metabolic regulation and oxidative stress responses. Collectively, these findings suggest that fermentation of SB1075-fermented soy yoghurt enhances the functional metabolite profile and may contribute to improved glycaemic regulation in diabetic mice. However, further studies involving targeted validation and clinical investigations will be required to confirm these mechanistic insights and evaluate the translational potential of SB1075-fermented soy yoghurt as a functional dietary intervention for metabolic health.\n\nID: 42033495\nTitle: Inhibition of SARS-CoV-2 spike S1-ACE2 binding interaction and downregulation of ACE2 gene expression by Malaysian stingless bee honey and its bioactive compound, stilbamidine (SDC).\nAbstract: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus infects host cells by binding to angiotensin-converting enzyme 2 (ACE2). Stilbamidine (SDC), a compound identified in Malaysian Kelulut honey (KH), has been reported to exhibit favourable binding affinity towards ACE2. This study aims to determine the effects of KH and SDC on the binding of spike protein to the ACE2 receptor, as well as to assess their modulatory potential on ACE2 gene and protein expression in lung and kidney cells. KH, SDC, and MLN 4760 (ACE2 inhibitor) were tested using an in vitro spike S1:ACE2 inhibition assay. Their modulatory effects on the ACE2 gene and protein expression were further examined through real-time PCR and western blot analysis. KH inhibited the binding of Spike S1 to ACE2, surpassing MLN4760, with maximum effects (Emax) of 82.66\u2009\u00b1\u20090.24% and 59.81\u2009\u00b1\u20098.00%, respectively, while the Emax for SDC was 19.93\u2009\u00b1\u20090.4%. KH caused a significant, dose-dependent downregulation of ACE2 gene expression in kidney-derived Vero E6 cells after 24\u00a0h of treatment, whereas SDC reduced ACE2 gene expression in lung-derived A549-ACE2-TMPRSS2 cells after 72\u00a0h. Nevertheless, ACE2 protein expression remained unchanged following both treatments. KH and SDC inhibit the binding of the SARS-CoV-2 spike S1 protein to the ACE2 receptor and reduce ACE2 gene expression. The efficacy of ACE2-targeted interventions may be limited by ACE2 polymorphisms and inter-individual expression differences. Further in vivo studies are needed to confirm their prophylactic and therapeutic potential against SARS-CoV-2 infection.\n\nID: 41995207\nTitle: Effect of Capsicum annuum leaf extract addition timing on yogurt bioactivity, digestibility, and cellular antioxidant defence.\nAbstract: Capsicum leaves contain notable levels of bioactive compounds, making them a potential functional ingredient for fermented dairy systems. During fermentation, microbial activity can modify these compounds, suggesting that the timing of extract incorporation may influence product quality. In this study, yogurt was supplemented with capsicum leaf extract (CLE) either before fermentation (Pre-L) or after fermentation (Post-L) to compare the effects of microbial exposure on physicochemical properties, bioactive activities, digestibility, and cellular antioxidant responses. CLE moderated acidification, with Pre-L maintaining a higher pH during fermentation. LAB viability was above 8 log CFU g-1 throughout storage in all samples. CLE supplementation increased phenolic content and antioxidant activity, with Pre-L showing superior retention during storage. In contrast, Post-L preserved enzyme-inhibitory activity more effectively, with smaller losses in \u03b1-amylase and \u03b1-glucosidase inhibition compared to Pre-L. During in vitro digestion, CLE enhanced phenolic bioaccessibility and proteolysis. Peptidomic analysis revealed approximately two-fold higher soluble peptide abundance in Pre-L, while Post-L showed the greatest hydrolysis during intestinal digestion, confirming timing-dependent modulation of proteolysis. In RAW 264.7 macrophages, CLE-supplemented yogurts reduced H2O2-induced oxidative stress and preserved antioxidant defence, with Pre-L showing the strongest cytoprotection. Overall, the timing of incorporation offers distinct benefits. Pre-L enhances antioxidant retention and cellular protection, whereas Post-L improves protein digestibility.\n\nID: 41962904\nTitle: Clover Honey Limits Survival of Enterotoxigenic Escherichia coli in an In Vitro Gastric Model and Reduces In Vitro Fermentation pH of Small Intestine Microbes.\nAbstract: Honey has well-described antimicrobial properties in wound healing, but little is known about its effects within the gastrointestinal tract. We used in vitro gastric digestion and fermentation of clover honey to investigate its potential interactions with small intestine bacteria (SIB), the foodborne pathogen enterotoxigenic Escherichia coli (ETEC), and small intestine epithelial cells. In vitro gastric digestions of sterile-filtered honey, and a simple sugar control were performed with 1 \u00d7 108 colony-forming units (CFU)/mL ETEC H10407. ETEC CFU and pH were measured, and the resulting digesta were added to batch fermentations with SIB, in the form of a mock community or ileal aspirate from 6 healthy donors. SIB fermentations were characterized by 16S rRNA amplicon sequencing and application of fermentation supernatants to mature Caco-2 cell monolayers for analysis of changes in transepithelial electrical resistance (TEER) and interleukin (IL)-8 production. Differential abundance of bacterial taxa detected by 16S rRNA sequencing between the honey and sugar conditions was tested using an Analysis of Compositions of Microbiomes with Bias Correction 2. Differences in ETEC CFU, media pH, and changes in TEER and IL-8 production between the honey and sugar conditions were tested by linear mixed effects modeling with post hoc least-squares means analysis. Under pH 2.5 in vitro gastric digestion conditions, ETEC CFU decreased significantly (P < 0.0001) more in the presence of clover honey (0.0035% input) than in a sugar control (0.036% input). The pH of SIB fermentation media was significantly reduced (P < 0.0001) with digested honey relative to sugar. Honey fermentation supernatant from human ileal communities challenged with ETEC elicited a greater improvement in TEER (3.68 compared with -0.80, P = 0.0479) relative to the same fermentations performed with control. Honey limits the survival of ETEC H10407 within an in vitro gastric environment at low pH. Clover honey may also impart decreased pH and potential improvement in in vitro epithelial cell barrier integrity in the presence of a pathogen.\n\nID: 41956642\nTitle: Multi-omics reveal the mechanism of Plantaricin BM-1 in controlling yoghurt post-acidification by affecting the membrane and metabolism of Lactobacillus delbrueckii subsp. bulgaricus.\nAbstract: The post-acidification of fermented milk is primarily caused by the sustained acid production of Lactobacillus delbrueckii subsp. bulgaricus during storage at ambient temperature, which significantly compromises product quality. Results from growth curves, acid production assays, and multiple microscopy techniques (laser scanning confocal microscopy, scanning electron microscopy, and transmission electron microscopy) collectively demonstrate that 256\u00a0AU/mL plantaricin BM-1 alters the morphology and cell membrane permeability of L. bulgaricus YR, reducing its acid production capacity while preserving its viability. Transcriptomic analysis revealed that this treatment significantly upregulated fatty acid metabolism and the gene LDB_RS05285, and downregulated atpE in L. bulgaricus YR. Metabolomics further revealed significant alterations in membrane-associated fatty acids and sterol lipids, corroborating BM-1's influence on cell membrane structure. Integrating observational, transcriptomic, and metabolomic data, it is concluded that 256\u00a0AU/mL plantaricin regulates post-fermentation acidification by modulating membrane permeability and structure, thereby controlling the expression of marker genes LDB_RS05285 and atpE. Storage experiments demonstrate that BM-1 addition maintains yoghurt pH\u00a0\u2265\u00a03.9 for 21\u00a0days at ambient temperature, effectively retarding post-acidification.\n\nID: 42543745\nTitle: The Potential Role of Two Red Macroalgae (Asparagopsis taxiformis and A. armata) That Promote Anti-Methanogenic Activities in Laboratory Conditions.\nAbstract: The objectives of this study were to evaluate the effects of two red macroalgae species (RMS; Asparagopsis taxiformis and A. armata) on rumen fermentation profiles, greenhouse gas (GHG) emissions, microbiome changes, and anti-methanogenic activities. The two RMSs were included at dietary levels of 0%, 2%, and 4% (as-fed basis) in an in\u00a0vitro experiment with triplicate incubations (n\u2009=\u20093). Gases were collected using an ANKOM Gas Production system and analyzed for methane (CH4) and nitrous oxide (N2O) via gas chromatography. The RMS supplementation increased total gas, lactate, butyrate, valerate, hexanoate, heptanoate, 4-ethylphenol production, and AGR (non-glucogenic [acetate\u2009+\u2009butyrate]/glucogenic [propionate]) ratio (p\u2009<\u20090.01), while reducing production of CH4 (mg/g DM), acetate, propionate, iso-butyrate, phenylpropionate, phenylacetate, and acetate/propionate (A/P) ratios (p\u2009<\u20090.01), and in\u00a0vitro dry matter digestibility (IVDMD; % DM) (p\u2009<\u20090.01) as RMS supplementation increased. With both algal species present, there were decreases in Actinobacteria, Firmicutes (p\u2009<\u20090.001), Firmicutes/Bacteroidetes ratio (F/B), and Methanobrevibacter sp. (p\u2009<\u20090.01), but increases in Spirochetes, Proteobacteria (methanotrophs; p\u2009<\u20090.001), Candidatus methanomethylophilus alvus (CMC), and non-methanogenic archaea Thermoplasma sp. (p\u2009<\u20090.001) at 2% and 4% DM. Therefore, it may be possible to suppress methanogenesis both directly and indirectly by adding RMS.\n\nID: 42543330\nTitle: [Construction of a long-lived engineered yeast and its efficient catalytic synthesis of ursodeoxycholic acid].\nAbstract: Ursodeoxycholic acid(UDCA) is a first-line drug for the clinical treatment of hepatobiliary diseases. The bioconversion of chenodeoxycholic acid(CDCA) based on whole-cell catalysis provides an important alternative approach for its green production. However, during fermentation, cellular aging and CDCA-induced stress lead to decreased stability of the catalytic system, which severely restricts its industrial application. This study took the extension of cellular chronological lifespan as the entry point, and systematically evaluated the effects of overexpressing the chronological lifespan regulatory factor heme activator protein 4 gene(HAP4) on whole-cell catalytic performance. The results showed that, under CDCA stress conditions after 8 days of fermentation, the survival rate of cells overexpressing HAP4 was 4.5-fold higher than that of the wild type, indicating that HAP4 overexpression significantly prolonged the CLS of Saccharomyces cerevisiae. Furthermore, by screening efficient genetic elements, an efficient catalytic module was obtained, consisting of 7\u03b1-hydroxysteroid dehydrogenase(7\u03b1-HSDH) from Escherichia coli and RT-7\u03b2-hydroxysteroid dehydrogenase(RT-7\u03b2-HSDH) from Ruminococcus torques. These enzymes were assembled in S. cerevisiae BY4742 to construct an efficient CDCA whole-cell catalytic strain, BY-RT, which achieved a UDCA conversion rate of 96.0%. On this basis, HAP4 was further overexpressed to obtain a long-lived engineered strain, BY-RT-HAP4. After 20 days of shake-flask fermentation, the catalytic efficiency of BY-RT-HAP4 remained at 44.4%, representing a 14.8-fold increase compared with BY-RT. Finally, industrial fermentation conditions were simulated in a 5 L bioreactor to systematically evaluate the effect of enhanced HAP4 expression on UDCA whole-cell catalytic performance. Under conditions of greater environmental stress and higher substrate concentration stress, the catalytic efficiency of BY-RT-HAP4 at the end of fermentation was still 13.4% higher than that of BY-RT. These results demonstrate that enhanced HAP4 expression can effectively maintain cellular activity and metabolic homeostasis, significantly improve the whole-cell conversion efficiency of UDCA, and provide a new metabolic engineering strategy and theoretical basis for the green and efficient biosynthesis of UDCA.\n\nID: 42543229\nTitle: [Effects of Pediococcus acidilactici fermentation on the quality and functional properties of mulberry juice].\nAbstract: To investigate the effects of Pediococcus acidilactici fermentation on mulberry juice quality. Fresh mulberry juice was used as the raw material and inoculated with P. acidilactici strain 003W to establish a fermentation system. After fermentation at 37 \u2103 for 48 h, the active components (total phenolics and anthocyanins), physicochemical indexes (pH, total acid content, reducing sugar content), antioxidant activity (DPPH and ABTS+ radical scavenging rates), and electronic tongue flavor characteristics (sourness, astringency, richness, etc. ) were evaluated before and after fermentation. The result showed that after fermentation, the total phenolic content increased from 11.01 mg GAE/mL to 13.41 mg GAE/mL, and the anthocyanin content increased from 0.60 mg RE/mL to 0.79 mg RE/mL. The pH value decreased from 5.70 to 4.34; the total acid content (expressed as lactic acid) increased from 4.10 g/L to 12.24 g/L; and the reducing sugar content (expressed as glucose) decreased from 85.00 mg/mL to 75.00 mg/mL. The DPPH free radical scavenging rate and ABTS+ free radical scavenging rate reached 40.08% and 49.87% from 18.00% and 28.00%(P<0.05). Electronic tongue analysis indicated that the sourness and richness of fermented mulberry juice were enhanced, while the astringency was significantly reduced, resulting in a more harmonious flavor profile. This study demonstrates that fermentation by P. acidilactici 003W effectively enhances the content of active components, antioxidant capacity, and flavor characteristics of mulberry juice, offering a scientific foundation for developing high-value probiotic mulberry beverages.\n\nID: 42543072\nTitle: Enhancing Berseem (Trifolium alexandrinum L.) Ensiled With Molasses by Bioactive Agents: Effects on Ensiling Characteristics, Aerobic Stability, Rumen Fermentation, and Characteristics In\u00a0Vitro.\nAbstract: This study investigated the effects of plant-derived bioactive compounds on the fermentation characteristics and aerobic stability of berseem (Trifolium alexandrinum) silage and evaluated their impact on ruminal fermentation. In Experiment 1, curcumin, resveratrol, eugenol, limonene, and thymol were applied at 400 and 800\u2009mg/kg fresh matter in combination with molasses (50\u2009g/kg) and ensiled for 60\u2009days to screen their effects on silage quality. Bioactive supplementation modified fermentation in a compound- and dose-dependent manner, reflecting differences in physicochemical properties and antimicrobial selectivity. Among the tested compounds, eugenol was the most effective in enhancing silage fermentation and aerobic stability, as it reduced pH, increased lactic acid concentration (p\u2009<\u20090.05), and maintained Flieg's score comparable to the control. Experiment 2 evaluated the ruminal consequences of eugenol-treated silage using in\u00a0vitro incubation at 24 and 48\u2009h. Eugenol supplementation reduced nutrient degradability and microbial protein synthesis at 48\u2009h and decreased methane production at both incubation times (p\u2009<\u20090.05). Overall, eugenol showed promising effects for improving silage preservation and aerobic stability; however, it reduced in\u00a0vitro nutrient degradability and microbial protein synthesis, suggesting that optimization of inclusion strategies is required to minimize potential negative effects on ruminal nutrient utilization.\n\nID: 42541634\nTitle: PEGylated Liposomal Resveratrol Induces Region-Specific Redox Modulation Without Behavioral or Neurotrophin Recovery in a VPA Model of Autism.\nAbstract: Autism Spectrum Disorder (ASD) is associated with neuroinflammation and oxidative stress that disrupt neurodevelopmental processes. Resveratrol (RSV) is a polyphenol with antioxidant and anti-inflammatory properties, but its poor bioavailability limits therapeutic use. This study investigated whether PEGylated liposomes encapsulating RSV (LipRSV) could modulate oxidative and behavioral alterations in a valproic acid (VPA)-induced rat model of ASD.\u00a0PEGylated LipRSV were synthesized, characterized as hemocompatible, and administered to offspring from postnatal day (PND) 6 to 27. Behavioral tests included developmental milestones, olfactory discrimination, negative geotaxis, open field, and three-chamber social interaction. Oxidative stress markers and neurotrophins (BDNF, NGF) were quantified in the following brain regions: hippocampus, hypothalamus, striatum, cerebellum, frontal and posterior cortex.\u00a0LipRSV exerted limited and region-dependent redox effects, reducing ROS levels only in the hippocampus, cerebellum, and posterior cortex, while failing to improve behavioral outcomes and being associated with unfavorable neurochemical alterations, including reduced BDNF and NGF levels. Importantly, LipRSV also induced behavioral deficits, redox imbalance, and neurochemical alterations in control animals, indicating treatment-related effects in the absence of VPA exposure.\u00a0LipRSV modulated oxidative stress in a region-dependent manner without improving behavioral deficits in the VPA model and was associated with reduced BDNF and NGF levels. This study provides evidence that modulation of oxidative stress alone is insufficient to rescue behavioral phenotypes in the VPA model of ASD. These findings highlight the partial neurochemical efficacy and translational limitations of this formulation, suggesting the need for optimized nanocarrier design and dosing strategies in ASD pharmacotherapy.\n\nID: 42538615\nTitle: Pulp Callus Extract From Malus domestica var. Mela Rosa Marchigiana Preserves Intestinal Barrier Integrity and Confers Neuroprotection in a Gut-Brain Axis Co-Culture Model.\nAbstract: The gut-brain axis is a key target in neuroinflammatory disorders. We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference. These findings suggest MRME as a promising nutraceutical candidate for gut-brain axis dysregulation.\n\nID: 42536723\nTitle: Cellular stress triggers degradation and global redistribution of RNAPII.\nAbstract: Transcription is essential for cellular stress response. However, how RNAPII respond to and are regulated during stress are poorly understood. We show that RNAPII is degraded during many types of cellular stresses. In osmotic stressed cells, the TNF\u03b1-p38 pathway was activated and promoted the neddylation of the CUL1 E3 ligase complex, which interacted with RPB1 through FBXO11 to ubiquitylate and degrade RNAPII. This caused genome wide RNAPII binding reduction, but prevented RNAPII binding loss from genes with low promoter GC content. This redistribution protected the RNAPII loss from stress response genes in the cell adhesion, MAPK and GPCR pathways. RNAPII redistribution is vital for cell survival, as degradation blockage resulted in the loss of RNAPII from low GC promoters and compromised stress response from disrupted cell adhesion to increased apoptosis. Thus, rapid RNAPII degradation and RNAPII redistribution are components of the cellular stress response to benefit cell survival.\n\nID: 42536279\nTitle: TRIM9-Mediated Degradation of SMAD4 Promotes Pyroptosis and Disruption of the Endothelial Barrier in Aortic Dissection Disease.\nAbstract: Aortic dissection (AD) is a life-threatening cardiovascular disease with exceedingly high mortality, particularly during the acute phase. Ubiquitination modification is implicated in the pathogenesis of cardiovascular diseases through diverse biological processes. However, the role of TRIM9, an E3 ubiquitin ligase, in AD remains unexplored. In this study, the expression profiles of TRIM9 and SMAD4 were analyzed using clinical samples, as well as Angiotensin II (Ang II)-induced mouse and human aortic endothelial cell (HAEC) models. Endothelial barrier function in AD was assessed through CCK-8 assays, vascular permeability measurements, immunofluorescence staining, hematoxylin-eosin and Verhoeff's van Gieson staining, and Western blot analysis. The underlying molecular mechanisms were elucidated using quantitative real-time PCR, immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and enzyme-linked immunosorbent assay (ELISA). TRIM9 was markedly overexpressed, whereas SMAD4 was significantly downregulated in AD. Knockdown of TRIM9 attenuated endothelial permeability, preserved the endothelial barrier integrity, and inhibited pyroptosis both in vivo and in vitro. Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression. Collectively, these findings demonstrate that elevated TRIM9 expression aggravates AD progression through SMAD4 destabilization, offering novel therapeutic insights for AD management.\n\nID: 42536203\nTitle: Decoding mitochondrial apoptosis in ischemic stroke via a miR-21a-3p/Plaur-centered regulatory network.\nAbstract: Ischemic stroke is a major cause of death and disability, and current therapies only partly limit secondary brain injury driven by apoptosis and oxidative stress. Mitochondria dependent cell death is a key contributor, but the upstream regulatory networks and cell type specific effectors remain unclear. Single cell RNA sequencing, bulk RNA sequencing and miRNA profiling from mouse middle cerebral artery occlusion models were integrated to identify mitochondrial apoptosis related pathways and key regulators. Cell type composition and differentially expressed genes were analyzed by scRNA-seq, intersected bulk datasets were used to define shared apoptosis related genes, and miRNA target prediction nominated candidate miRNA-mRNA pairs. Hypoxia treated BV2 microglia and bEnd.3 endothelial cells were used for functional validation by qPCR, western blotting, flow cytometry, LDH release, CCK-8 and dual luciferase assays. scRNA-seq identified twelve brain cell populations and showed that endothelial cells, monocytes, astrocytes and microglia display the most prominent changes after ischemia, with Gene Ontology enrichment repeatedly highlighting \"apoptotic mitochondrial changes\" (GO:0008637). Intersecting two bulk RNA-seq cohorts recovered the same pathway and four candidates (Hk2, Pycard, Fas and Plaur), with Plaur most strongly dysregulated in endothelial and myeloid cells. miRNA profiling and multi database prediction highlighted miR-21a-3p as a putative upstream regulator of Plaur. In vitro, hypoxia increased Plaur and decreased miR-21a-3p. Plaur silencing reduced apoptosis, reactive oxygen species and LDH release and improved viability, while miR-21a-3p overexpression lowered Plaur and attenuated hypoxia induced injury; inhibition of miR-21a-3p had opposite effects. Dual luciferase assays confirmed direct binding of miR-21a-3p to the Plaur 3'UTR. The miR-21a-3p/Plaur axis links miRNA regulation to mitochondria associated apoptotic and oxidative damage pathways in ischemia related cellular models and represents a potential target for further mechanistic and translational studies in ischemic stroke.\n\nID: 42536189\nTitle: Screening and optimisation of crude exopolysaccharide production by marine Brevibacterium sp. JAB08 isolated from the jellyfish Chrysaora sp. from the coastal waters of Goa.\nAbstract: Marine jellyfish harbor diverse bacterial communities with potential biotechnological relevance. In this study, eleven bacterial isolates were obtained from different body parts (oral arms, gastric cavity, and mucus) of the jellyfish Chrysaora sp. collected from the coastal waters of Goa, India, and screened for exopolysaccharide (EPS) production. Among the screened isolates, Brevibacterium sp. JAB08 demonstrated the highest crude EPS production potential. Optimisation using a Box-Behnken Design coupled with response surface methodology identified sucrose 3% (w/v), inoculum size 2% (v/v), and an incubation period of 36\u00a0h as the optimal fermentation conditions with EPS yield of 4.26\u00a0g\u00a0l-1 in shake flask. Notably, this yield was achieved in 36\u00a0h, compared to 96\u00a0h required to reach a comparable yield under unoptimised conditions, indicating improved process efficiency, structural characterisation by FTIR revealed a neutral polysaccharide dominated by \u03b2-glycosidic linkages, while SEM revealed a porous, three-dimensional network of spheroidal aggregates. Overall, the results of the present study position jellyfish-associated microbes as a promising and largely unexplored source of exopolysaccharides with potential implications for sustainable marine biopolymer production following purification and compositional analysis.\n\nID: 42533119\nTitle: Comparative microbiome profiling of plant- and animal-derived traditional fermented foods from Mizoram, India using full-length 16S rRNA sequencing.\nAbstract: Traditional fermented foods represent complex microbial ecosystems shaped by substrate composition, indigenous processing practices, and local environmental conditions. However, the microbiomes of many traditional fermented foods from Northeast India remain poorly characterized. In this study, the bacterial communities associated with thirteen traditional fermented foods from Mizoram, India, representing both plant- and animal-derived fermentations, were characterized using full-length 16S rRNA gene sequencing on the Oxford Nanopore platform. Sequencing generated approximately 1.94 million high-quality reads, enabling high-resolution taxonomic profiling of the fermented food microbiomes. The microbial communities were predominantly composed of Bacillota, Pseudomonadota, and Cyanobacteriota, although their relative abundances varied considerably among fermented food types. Plant-derived fermented foods were enriched with fermentative bacterial genera, including Bacillus, Lactobacillus, Lacticaseibacillus, Pediococcus, and Weissella, whereas animal-derived fermented foods showed a greater abundance of anaerobic taxa, particularly Clostridium. Alpha diversity analyses demonstrated higher microbial richness in plant-derived fermented foods, while beta diversity revealed clear substrate-dependent clustering of microbial communities. Functional prediction indicated that metabolism-related pathways, particularly carbohydrate and amino acid metabolism, predominated across the fermented food microbiomes, and LEfSe analysis identified distinct microbial biomarkers associated with plant- and animal-derived fermentations. Collectively, these findings provide the first comprehensive microbiome characterization of traditional fermented foods from Mizoram and demonstrate that fermentation substrate is a major determinant of microbial community composition and predicted functional potential. Although full-length 16S rRNA gene sequencing improved taxonomic resolution, taxonomic interpretations were made cautiously at the genus level where appropriate because of the inherent limitations of 16S rRNA gene-based classification.\n\nID: 42533008\nTitle: Isolation and preliminary characterization of a glucan-type exopolysaccharide produced by Bacillus tequilensis strain HH from Egyptian fermented cucumber.\nAbstract: Exopolysaccharide (EPS) production is a common feature of microbial carbohydrate metabolism during fermentation; however, glucan-type EPS produced by Bacillus species in fermented vegetable systems remain insufficiently characterized. This study aimed to isolate an EPS-producing bacterium from naturally fermented cucumber and to perform a preliminary physicochemical and spectroscopic characterization of the produced polymer. An EPS-producing bacterial isolate was recovered and identified as Bacillus tequilensis, a member of the Bacillus subtilis species complex, based on 16\u00a0S rRNA gene sequence analysis. The extracellular polysaccharide was partially purified and analyzed using FTIR and \u00b9H NMR spectroscopy, revealing structural features consistent with a glucan-type EPS. Rheological analysis demonstrated a concentration-dependent increase in viscosity, confirming the macromolecular nature of the polymer in aqueous systems. Sucrose-hydrolyzing activity was detected under optimized conditions, indicating active carbohydrate metabolism associated with EPS production. In vitro cytocompatibility assessment using Vero and WI-38 cell lines showed high cell viability at low to moderate concentrations, with a dose-dependent reduction observed at higher levels. Overall, this study reports the isolation of an EPS-producing Bacillus tequilensis strain from Egyptian fermented cucumber and provides preliminary insights into the properties of its glucan-type exopolysaccharide, highlighting fermented vegetable microbiota as a potential source of functional biopolymers.\n\nID: 42532957\nTitle: Two Mechanisms One Molecule: Developing a 'Truly' Bifunctional Degrader Targeting Rpn13 and CRBN.\nAbstract: Targeted protein degradation (TPD) has emerged as a powerful strategy to eliminate disease-relevant proteins, yet current approaches remain largely constrained to hijacking ubiquitin ligases. We previously introduced ByeTACs, bifunctional molecules that directly recruit proteins to the proteasome for E-ligase independent degradation. Here, we report \"Truly\" degraders, a new class of dual-mechanism molecules that combine a ligand for the proteasomal receptor Rpn13 with a ligand for cereblon (CRBN) to simultaneously engage both ubiquitin-independent and ubiquitin-dependent degradation pathways. Structure-guided design identified an optimal linker length that supports efficient substrate processing, with the PEG4 derivative (Truly-4) inducing robust depletion of both Rpn13 and CRBN in several cancer cell types. Remarkably, Truly-4 is the first noncovalent small molecule shown to degrade full-length Rpn13, a target previously approached using covalent or domain-restricted strategies. Mechanistic studies confirmed that degradation of Rpn13 proceeds via CRBN-dependent E3 ligase activity, whereas CRBN degradation occurs through an E-ligase independent process, consistent with a ByeTAC mechanism. Importantly, Truly-4 induces selective cytotoxicity in hematologic and solid cancer cell lines but not in healthy cells, despite comparable Rpn13 depletion, indicating that dual degradation can uncouple target engagement from toxicity. These findings establish a generalizable framework for engineering bifunctional degraders that program the proteasome to execute parallel degradation mechanisms and highlight proteasome receptors as druggable nodes for selective destruction of disease-relevant proteins.\n\nID: 42531414\nTitle: An adaptor for feedback regulation of heme biosynthesis by a mitochondrial protease.\nAbstract: Heme biosynthesis is tightly coordinated to support essential functions without accumulating toxic porphyrins and depleting cellular iron. Heme induces degradation of the heme biosynthetic enzyme, 5-aminolevulinate synthase (ALAS), by the mitochondrial caseinolytic protease complex CLPX-CLPP (CLPXP), but the mechanism for heme-triggered degradation had not been elucidated. We found that polymerase delta-interacting protein 2 (POLDIP2) is a heme-sensing adaptor protein sufficient to reconstitute negative feedback degradation of ALAS by CLPXP. POLDIP2 was necessary to support ALAS turnover in cells and regulate heme production during erythropoiesis. POLDIP2 directly recognized and recruited heme-bound ALAS to CLPXP. Degradation initiation required a carboxyl-terminal element of ALAS, truncations of which cause an erythropoietic protoporphyria. Our findings establish a mechanism for conditional degradation by CLPXP that underlies erythropoietic protoporphyrias linked to CLPX and ALAS.\n\nID: 42530815\nTitle: Lactic-fermented red onion (Allium cepa L.) extract in drinking water improves feed efficiency, selectively modulates cecal microbiota, and reduces ammonia emission in heat-stressed yellow-feather chickens.\nAbstract: Heat stress is a major constraint to sustainable poultry production in tropical regions. This study evaluated the effects of Lactobacillus plantarum 1582-fermented red onion bulb extract (LFRO), supplied through drinking water, on growth performance, cecal microbiota, and excreta gas emissions in heat-stressed yellow-feather chickens. A total of 300 one-day-old male Rilai chicks were assigned to four treatments in a completely randomized design with five replicate pens of 15 birds each: unsupplemented control or LFRO at 25, 50, or 100\u00a0mg/L in drinking water. Birds were reared for 70 days under natural chronic tropical heat stress, with the temperature-humidity index predominantly within the severe-to-very severe range (28.9-31.1). Supplementation with 100\u00a0mg/L LFRO increased final body weight and body weight gain, reduced feed intake, and improved feed conversion ratio over the whole trial. The European Production Efficiency Index and Broiler Performance Efficiency Factor were also highest in the 100\u00a0mg/L group. Cecal 16\u00a0S rRNA sequencing showed no major changes in alpha- or beta-diversity, but several selected bacterial genera were modulated. LFRO at 50 and 100\u00a0mg/L reduced ammonia emission from excreta, whereas the other measured gases were not affected. This study shows LFRO at 100\u00a0mg/L is a natural drinking water supplement that improves feed efficiency and gut microbial balance in yellow-feathered chickens exposed to chronic tropical heat stress.\n\nID: 42530673\nTitle: ROS-Ca2+ signalling interplay is associated with cobalt-enhanced dendrobine-type total alkaloid production in Trichoderma longibrachiatum UN32.\nAbstract: Cobalt stress can promote the accumulation of dendrobine-type total alkaloids (DTTAs) in Trichoderma longibrachiatum UN32; however, the signalling mechanisms underlying this response remain unclear. In this study, we examined whether changes in Ca2+ and nitric oxide (NO) signalling were associated with ROS-related responses and cobalt-enhanced DTTAs production under cobalt stress. Co2+ treatment increased DTTAs accumulation together with intracellular hydrogen peroxide (H2O2), Ca2+ and NO levels. Among Ca2+ signalling inhibitors, neomycin (Neo) showed the strongest effect: 6 mM Neo reduced intracellular Ca2+ by 59.86%, DTTAs production by 33.70% and H2O2 levels by 25.50% compared with CoCl2 treatment. Time-course analysis further showed coordinated changes in H2O2, Ca2+ and DTTAs accumulation during fermentation. In contrast, L-NAME-mediated inhibition of NO synthesis did not significantly affect DTTAs production. These findings suggest that ROS-Ca2+ interplay is associated with cobalt-enhanced DTTAs accumulation in T. longibrachiatum UN32, whereas NO has a limited role under the tested conditions.\n\nID: 42530253\nTitle: Resveratrol-Mediated Regulation of Molecular and Cellular Signaling Networks in Polycystic Ovary Syndrome.\nAbstract: Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine-metabolic disorder characterized by dysregulated ovarian signaling, metabolic inflammation, insulin resistance, and aberrant angiogenesis, for which effective disease-modifying therapies remain limited. Resveratrol (RES), a pleiotropic polyphenol, has attracted increasing attention for its ability to modulate multiple molecular and cellular pathways implicated in PCOS pathophysiology. In this review, we synthesize current evidence to clarify how RES regulates key pathological signaling networks in PCOS, including ovarian follicular dysfunction, impaired insulin signaling, hyperandrogenism, oxidative stress, and vascular remodeling. Rather than merely cataloguing isolated mechanisms, we integrate findings from experimental models to highlight major convergent nodes-such as phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamycin (mTOR), sirtuin 1 (SIRT1)/AMP-activated protein kinase (AMPK), nuclear factor kappa-B (NF-\u03baB), and vascular endothelial growth factor (VEGF)-related pathways-through which RES may exert coordinated regulatory effects at the cellular and tissue levels. We further examine the available clinical studies to assess the translational relevance of these mechanistic insights, with particular emphasis on phenotypic heterogeneity, dose dependence, and the treatment window. Although clinical outcomes remain modest and variable, the available evidence suggests that RES may provide context-dependent benefits in selected PCOS subtypes. Collectively, this review offers a network-based framework linking the molecular actions of RES to the complex pathophysiology of PCOS and identifies key knowledge gaps that must be addressed to improve translational precision and therapeutic applicability.\n\nID: 42530049\nTitle: Microglia as Double-Edged Players in Ischemic Stroke.\nAbstract: Stroke has long been a leading cause of death and long-term disability worldwide. In recent years, more and more research has revealed that microglial responses to ischemic injury are highly heterogeneous and exhibit dynamic evolution over time, across brain regions, and under different metabolic states. This endows microglia with a dual regulatory role in both neurotoxicity and neuroprotection after ischemia: on one hand, they drive inflammatory responses, exacerbating secondary neuronal damage, blood-brain barrier disruption, and synaptic loss; on the other hand, they orchestrate debris clearance, vascular rebuilding, and neural repair. The traditional pro-inflammatory versus anti-inflammatory dichotomy is no longer sufficient to fully describe their complex functions. In this review we summarize recent advances in understanding the dual regulatory roles of microglia after ischemic stroke, with a focus on key mechanisms such as metabolic reprogramming, lipid metabolism regulation, inflammasome activation, and epigenetic modification. Furthermore, emerging therapeutic strategies targeting microglia and the challenges they face are discussed.\n\nID: 42528217\nTitle: Structure-Activity-Property Relationships of MZ1-Based Trivalent PROTACs Incorporating a 1,2,5-Trisubstituted Benzene Linker.\nAbstract: Studies on the structure-activity-property relationships of MZ1-based trivalent proteolysis-targeting chimeras (PROTACs) incorporating a trisubstituted benzene linker, particularly the 1,2,5-trisubstituted type, were conducted with a focus on the linker and the functional group introduced at the 5-position on the benzene ring. Introducing a polar, charged functional group at the end of the linker significantly increased the PROTAC's solubility. However, this polar group also significantly impaired the Brd4 degradation-inducing activity of these PROTACs, even though the PROTACs were designed not to disrupt the ternary complex formation among the POI, the E3 ligase, and the PROTAC. Capping the polar functional group restored the activity. These findings will be useful for designing functional PROTACs and PROTAC-based probes and will also help elucidate the modes of action of PROTACs.\n\nID: 42528048\nTitle: Exosome-Mediated Delivery of PROTACs for Targeted Protein Degradation in Cancer, Neurodegenerative, Infectious, and Inflammatory Diseases.\nAbstract: Proteolysis-targeting chimeras (PROTACs) are heterobifunctional molecules that hijack the ubiquitin-proteasome system to drive catalytic, sub-stoichiometric degradation of disease-associated proteins, offering a mechanistic advantage over occupancy-driven inhibitors and access to 'undruggable' targets. However, their clinical translation is constrained by high molecular weight, poor solubility, low oral bioavailability, inefficient membrane permeability, nonspecific biodistribution, off-target degradation, and the concentration-dependent 'hook effect.' Exosomes, nanoscale extracellular vesicles with innate biocompatibility, low immunogenicity, prolonged circulation, and the ability to cross barriers such as the blood-brain barrier, offer a biologically integrated platform to overcome these limitations. This review traces the evolution of PROTAC technology, delineates the challenges of conventional delivery, and evaluates the rationale for exosomal encapsulation, including cargo protection, intracellular trafficking, endosomal escape, and release kinetics. We examine natural and engineered exosomes spanning source selection, active loading strategies, and surface functionalization for tissue-specific homing and synthesize therapeutic applications across viral infections, cancer, neurodegenerative disorders, and inflammatory diseases. Proof-of-concept studies, such as camel milk-derived exosomes delivering the BRD4-targeting PROTAC ARV-825, demonstrate enhanced permeability, lower IC50 values, and improved oral bioavailability. Finally, we discuss key hurdles to clinical translation: scalable production, purification, and standardization, and outline future directions for exosome-mediated targeted protein degradation.\n\nID: 42525141\nTitle: SOX9 knockdown alleviates A\u03b21\u201142\u2011induced neuroinflammation by regulating microglial polarization via inactivation of the ASK1/JNK signaling pathway.\nAbstract: Neuroinflammation driven by microglial polarization imbalance plays a key role in A\u03b2-induced neuronal injury, a core pathological feature of Alzheimer's disease (AD). The transcription factor SOX9 has been linked to AD progression, but its mechanism remains unclear. SOX9 expression was measured in peripheral blood mononuclear cells from 24 patients with AD and 24 age-matched healthy controls and correlated with Montreal Cognitive Assessment scores. An A\u03b21-42-stimulated BV-2 cell model was used to investigate the effects of SOX9 and apoptosis signal-regulating kinase 1 (ASK1) on microglial polarization. Neuronal injury was evaluated in a BV-2/SH-SY5Y co-culture system. The transcriptional regulation of ASK1 by SOX9 was examined using dual-luciferase reporter and chromatin immunoprecipitation assays. ASK1 overexpression and the ASK1 inhibitor GS-4997 were used for mechanistic validation. SOX9 expression was increased in peripheral blood mononuclear cells from patients with AD and was negatively correlated with cognitive function. SOX9 was also upregulated in A\u03b21-42-stimulated BV-2 cells. SOX9 overexpression enhanced M1-associated inflammatory markers and reduced M2-associated markers, whereas SOX9 knockdown produced the opposite effects. In the co-culture system, SOX9 knockdown increased SH-SY5Y cell viability, reduced LDH release and apoptosis, increased Bcl-2 expression, and decreased Bax and cleaved caspase-3 expression. SOX9 bound to the ASK1 promoter and promoted ASK1 transcription. SOX9 silencing suppressed ASK1, JNK, and p38 phosphorylation, while ASK1 overexpression reversed the effects of SOX9 knockdown on microglial polarization and neuronal injury. Consistently, GS-4997 blocked the pro-inflammatory and neurotoxic effects induced by SOX9 overexpression. SOX9 exacerbates AD neuroinflammation by promoting microglial M1 polarization via the ASK1/JNK signaling axis.\n\nID: 42523672\nTitle: Osteoimmunological impacts of micro/nanoplastics: systemic translocation, inflammatory responses, and bone remodeling disruption.\nAbstract: Ingested environmental micro- and nanoplastics (MNPs) may represent an emerging systemic health concern. Although toxicological research has mainly focused on the gastrointestinal tract, increasing evidence suggests that the highly vascularized bone marrow may also be a relevant site for MNP accumulation. This narrative review proposes a \"gut-immune-bone\" axis linking intestinal barrier disruption, systemic translocation, and potential deposition within the bone marrow niche. Current experimental evidence, together with limited human detection data, suggests that MNPs may disturb osteoimmunological homeostasis by impairing osteogenesis and promoting macrophage-associated osteoclastogenesis, thereby favoring bone remodeling imbalance. We summarize potential mechanisms, including oxidative stress, nuclear factor-\u03baB (NF-\u03baB) signaling, NOD-like receptor protein 3 (NLRP3) inflammasome activation, gut microbiota dysbiosis, endocrine disruption, and MNP-heavy metal co-exposure. We also discuss susceptible pediatric and geriatric populations and highlight the need to incorporate osteoimmunological endpoints into future MNP risk assessment.\n\nID: 42514440\nTitle: The Effect of a Low-FODMAP Diet on Quality of Life, Severity of Symptoms and Leaky Gut in Patients with Irritable Bowel Syndrome.\nAbstract: Objective: We aimed to investigate the effects of a low-FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) diet on symptom severity, quality of life, and fecal zonulin levels in patients with irritable bowel syndrome (IBS). Methods: Twenty-four patients with IBS were prospectively randomized to either a low-FODMAP diet (LFD) or a traditional diet (TD) for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life (IBS-QOL), and fecal zonulin levels were assessed at baseline and week 4 in both groups. In the LFD group, FODMAP-containing foods were gradually reintroduced after week 4, and all assessments were repeated at week 16. Changes in laboratory parameters, fecal zonulin levels, IBS-SSS, and IBS-QOL scores were evaluated. Results: Fecal zonulin levels did not differ significantly between groups at baseline or week 4, and no significant within-group changes were observed over time (all p > 0.05). IBS-SSS scores improved significantly at week 4 in both groups compared with the baseline (p < 0.05), with no significant difference in the magnitude of improvement between groups (p > 0.05). In the LFD group, IBS-SSS scores increased at week 16 compared with week 4 (p < 0.05). Similarly, IBS-QOL scores improved significantly at week 4 in both groups (p < 0.05), without significant between-group differences (p > 0.05). In the LFD group, IBS-QOL scores returned to baseline levels by week 16. Conclusions: Both the LFD and TD were associated with significant short-term improvements in IBS symptom severity and quality of life. However, the LFD did not demonstrate superiority over the TD. Furthermore, no statistically significant changes in fecal zonulin levels were observed in either group, although these findings should be interpreted cautiously. In the LFD group, some improvements observed at week 4 were attenuated following FODMAP reintroduction at week 16; however, these findings represent exploratory within-group observations and should not be interpreted as evidence of long-term treatment efficacy or sustained benefit following FODMAP reintroduction.\n\nID: 42356295\nTitle: From Leaky Gut to a Vulnerable Brain: Obesity-Associated Gut Barrier Failure in Colorectal Cancer and Cognitive Dysfunction.\nAbstract: Obesity is a major risk factor for colorectal cancer (CRC) and is increasingly recognized as a contributor to cancer-related cognitive impairment; however, the mechanistic pathways linking metabolic dysfunction, tumor progression, and brain dysfunction remain incompletely defined. Emerging evidence indicates that obesity-induced gut microbial dysbiosis and intestinal barrier disruption may serve as a biologically plausible mechanism connecting these processes via the gut-brain axis although direct clinical causality remains to be firmly established. In obesity, alterations in gut microbiota composition characterized by depletion of barrier-protective taxa and enrichment of pro-inflammatory and genotoxic pathobionts compromise epithelial tight-junction integrity and promote metabolic endotoxemia. The translocation of microbial products, including lipopolysaccharide, sustains chronic systemic inflammation, accelerates CRC progression, and remodels the tumor microenvironment. Notably, these peripheral inflammatory signals extend beyond the intestine and tumor, disrupting blood-brain barrier integrity, activating microglia and astrocytes, and impairing synaptic plasticity within hippocampal and frontal networks. Clinically, these processes manifest as cancer-related cognitive impairment (CRCI), with predominant deficits in attention, processing speed, and working memory, which are often detectable around the time of diagnosis and independent of chemotherapy exposure. This review synthesizes in vivo, in vitro, and human evidence into a proposed theoretical \"two-barrier failure\" model of obesity-associated CRC and cognitive dysfunction. In addition to mechanistic synthesis, we discuss barrier-centered therapeutic strategies, including targeted probiotics, postbiotics, SCFA supplementation, obesity management through dietary and weight-loss interventions, and potential pharmacological approaches to epithelial and neurovascular barrier protection. We also outline testable clinical trial designs for evaluating these interventions in obesity-associated CRC.\n\nID: 42311683\nTitle: Gut microbiota modulation in the prevention and treatment of heat stroke.\nAbstract: In recent years, heat stroke (HS) have been reported with increasing frequency, and this trend is hard to separate from broader environmental changes, including climate change, recurrent extreme heat events, and air pollution. When people are exposed to high-temperature environments for a prolonged period, especially during intense physical activity, the condition may progress to HS. HS is an acute and potentially fatal disorder that can deteriorate rapidly if not treated in time. The intestine appears to be particularly vulnerable during HS. HS can disrupt intestinal tight junctions and weaken the barrier function of the gut, leading to what is commonly described as a \"leaky gut.\" Once this barrier is compromised, microbial products such as lipopolysaccharides can enter the bloodstream. These molecules may then activate immune cells, promote excessive cytokine release, and eventually drive a systemic inflammatory response. In severe cases, this inflammatory process can develop into systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Current evidence increasingly suggests that intestinal injury is not simply a secondary result of HS. Rather, it may serve as an important early event in the development and progression of the disease. Still, it should be noted that much of the available evidence comes from preclinical studies, and strong clinical confirmation is still limited. Probiotics have attracted attention because they may help reduce the occurrence and severity of HS by maintaining gut microbiota balance and regulating intestinal immune responses. However, since most supporting data are still derived from animal experiments, their protective effects in humans need to be interpreted carefully. Another point worth emphasizing is that the gut is not working alone. Through gut-organ communication networks, the intestinal microbiota can interact with distant organs, including the liver, lungs, and brain. These gut-liver, gut-lung, and gut-brain axes may help explain how HS leads to injury beyond the intestine itself. In this review, we summarize current findings on how modulation of the gut microbiota may improve intestinal thermotolerance and strengthen barrier function, with the aim of providing useful insights for the prevention and treatment of HS in clinical practice.\n\nID: 42304659\nTitle: The leaky gut and microbiome in critical illness: emerging insights into microbial \"translocation\".\nAbstract: Microbial translocation has long been viewed as a nonspecific consequence of gut barrier failure in critical illness, with downstream effects attributed primarily to the host immune response. This review examines emerging evidence that the gut microbiome plays a more active and specific role in this process than previously appreciated. Dysbiosis during critical illness directly contributes to barrier dysfunction through depletion of metabolites that sustain epithelial integrity. Culture-independent approaches have revealed that gut-derived organisms are a major reservoir for secondary infection, with translocation governed by microbial virulence, community dynamics, and immune cell-mediated transport rather than barrier permeability alone. In parallel, organism-specific microbial components - including structurally diverse forms of lipopolysaccharide and bacterial DNA detected across multiple blood fractions - enter the circulation and differentially modulate host immune responses. Recent studies link circulating microbial DNA composition to distinct inflammatory phenotypes in sepsis and acute respiratory distress syndrome, suggesting these signals contribute to clinical heterogeneity. These findings support a revised framework in which translocation reflects the composition of the dysbiotic gut, not barrier integrity alone. Integrating microbial data with host phenotyping may enable more precise risk stratification and microbiome-informed therapeutic strategies in critical illness.\n\nID: 42173456\nTitle: Supplementation with bovine thymus extract improves survival, motility and stress resistance in C. elegans.\nAbstract: Nutritional support for healthy aging is an active field of research. Bovine organ extracts, and glandular therapy in general, became popular in the 1900s, but their effect on healthy aging is unexplored, and their mechanisms of action are unclear. Here, we evaluated three bovine thymus materials with regards to their effect on healthy aging in C. elegans: two thymus extracts, a nuclear fraction (TNF) and a cytosolic fraction, and desiccated bovine thymus. All three materials extended C. elegans mid-life survival and improved mid-life motility. RNA sequencing revealed that TNF treatment elicited noticeable changes in the expression of genes related to the extracellular matrix and those necessary for defense responses. This was accompanied by protection from oxidative stress (paraquat) and pathogen (Pseudomonas aeruginosa)-induced early death and leaky gut. This study validates the hypothesis that dietary supplementation with bovine thymus extract can support healthy aging and protect C. elegans from environmental stressors.\n\nID: 42148126\nTitle: All roads lead to NF-\u03baB: the NF-\u03baB pathway as a major target for intestinal inflammatory disorders.\nAbstract: This review aims to comprehensively examine the role of the NF-\u03baB signalling pathway as a central mediator of intestinal inflammation, integrating evidence from microbiota dysbiosis, immune activation, neutrophil extracellular trap (NET) formation, and the gut-brain axis, and to evaluate current and emerging NF-\u03baB-targeted therapeutic strategies for inflammatory intestinal disorders. The NF-\u03baB family comprises transcription factors that control key processes in immune responses and inflammation by regulating specific gene expression. NF-\u03baB signalling mediates intestinal inflammatory responses at different levels including cytokine secretion, inflammasome signalling, the recruiting of immune cells and antibody production. The NF-\u03baB pathway acts as sensor of microbiota changes and is strongly activated by bacterial toxins such as LPS, MDP or TMAO. Thus, microbial dysbiosis activates pro-inflammatory NF-\u03baB, producing epithelial barrier dysfunction that can lead to a \"leaky gut\" syndrome, allowing pro-inflammatory factors to leak into the systemic circulation. Consequently, the inflammation originating in the intestine spreads to other organs like the brain, where it might contribute to the development of neurodegenerative disorders, such as Parkinson's disease. In addition, NF-\u03baB also promotes intestinal inflammation in response to Neutrophil Extracellular Traps (NETs) formation, promoting tissue damage and lesions of the intestinal epithelial lining. Therefore, a dysregulated NF-\u03baB signalling appears often in multiple chronic intestinal inflammatory conditions, such as Crohn's Disease (CD) and Ulcerative Colitis (UC), Celiac Disease (CeD) or microscopic colitis. In addition, NF-\u03baB is strongly activated in Irritable Bowel Syndrome (IBS) and in acute intestinal inflammation such as Necrotizing Enterocolitis (NEC). Confirming this evidence, inhibition of the NF-\u03baB pathway by drugs, peptides or natural compounds has been demonstrated to ameliorate the symptoms in many of these inflammatory diseases. In this review, we explore the role of the NF-\u03baB pathway in intestinal inflammation, given its essential role in linking microbiota dysbiosis, infections and chronic inflammation. Finally, we propose the NF-\u03baB pathway as a main therapeutic target for inflammatory intestinal disorders and discuss current inhibitory therapies in use.\n\nID: 42009106\nTitle: Chronic inflammation in virus-suppressed people living with human immunodeficiency virus infection: A microbiology-oriented perspective on gut barrier failure, microbial translocation, and immune activation.\nAbstract: Potent antiretroviral therapy (ART) has transformed human immunodeficiency virus (HIV) infection into a chronic manageable condition; however, many people living with HIV (PLWH) exhibit persistent immune activation and inflammation despite long-term virological suppression. Residual inflammation is strongly associated with an increased risk of cardiovascular disease, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, cancer, and neurocognitive impairment. This review summarizes the current evidence on the microbiology-oriented mechanisms that sustain this state. We first outline a multifactorial network in which incomplete repair of intestinal mucosal damage, dysbiosis, reduced short-chain fatty acid production, and disturbed bile acid metabolism generate a patchy \"leaky gut.\" Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits. These inputs interact with intermittent HIV antigen expression from latent reservoirs, inflammatory cell death, chronic coinfections, lymphoid tissue fibrosis, mitochondrial dysfunction, and traditional lifestyle-related risk factors. Together, they establish a self-reinforcing gut-liver-immune axis that maintains low-grade inflammation and a procoagulant milieu under viral suppression. We then link these mechanisms to organ-specific complications and review the intervention data, focusing on early ART initiation, statin therapy, and cotrimoxazole prophylaxis as a proof-of-concept that modifying inflammatory and mucosal pressures can improve outcomes. Finally, we highlight research priorities and argue that the effective prevention of long-term complications in virally suppressed PLWH requires combination strategies targeting multiple nodes of this network, with particular attention to gut barrier repair and microbiome modulation.\n\nID: 42003478\nTitle: JNK2 Is a Stress Integrator Driving Atrial Fibrillation Pathogenesis in Aging via Gut-Heart Crosstalk.\nAbstract: Atrial fibrillation (AF) is the most common arrhythmia and is associated with high morbidity and mortality, particularly in the aging population. Current treatment and prevention strategies remain suboptimal, highlighting the urgent need to better understand the mechanisms underlying aging-associated AF. We recently reported a causal role of the stress-activated kinase JNK2 (c-Jun N-terminal kinase 2) in aging-associated AF pathogenesis, mediated by JNK2-driven sarcoplasmic reticulum Ca2+ dysfunction. However, the mechanisms by which cardiac JNK2 is activated during aging to promote AF remain unclear. Emerging evidence suggests that interorgan crosstalk contributes critically to the development of cardiovascular diseases. A hyperpermeable gastrointestinal epithelial barrier (\"leaky gut\"), commonly observed in aged individuals, is associated with elevated levels of proinflammatory cytokines and an increased risk of AF. Although proinflammatory cytokines have been proposed as predisposing factors for AF, clinical and experimental studies have yielded inconsistent results, underscoring the complexity of inflammation-associated AF pathogenesis. Here, we investigated whether cardiac JNK2 integrates diverse stress stimuli, including proinflammatory cytokines and lipopolysaccharide, to drive AF pathogenesis. We used aged mice, intestinal epithelium-specific tight junction OD (occludin) knockdown (OD+/-) mice, and a well-established dextran sulfate sodium-induced leaky gut mouse model characterized by reduced gastrointestinal epithelial occludin expression. A series of physiological and molecular approaches was applied to assess cardiac and gastrointestinal responses. We found that leaky gut significantly activates atrial JNK2, which, in turn, drives Ca2+-triggered arrhythmic activity and increases AF inducibility in aged, dextran sulfate sodium-treated, and OD+/- mouse models. Restoration of gut barrier function in dextran sulfate sodium mice, a clinically relevant model, reduced AF susceptibility. Similarly, either JNK2 inhibition or TNF-\u03b1 (tumor necrosis factor \u03b1) blockade abolished the increased AF risk associated with leaky gut. Furthermore, we demonstrate, for the first time, that leaky gut-associated proinflammatory cytokines, including TNF-\u03b1 and IL-17A (interleukin-17A), together with lipopolysaccharide, activate cardiac JNK2. This activation promotes AF pathogenesis through JNK2-mediated arrhythmogenic mechanisms, including diastolic sarcoplasmic reticulum Ca2+ leak, Ca2+ waves, and delayed afterdepolarizations. Activated JNK2 functions as a pathological nodal integrator of leaky gut-associated stress signals, mediating gut-to-heart crosstalk and driving inflammation-induced AF pathogenesis. Targeting JNK2 may represent a novel therapeutic strategy for AF.\n\nID: 41972275\nTitle: Enhanced Antiaging Effect of Fermented Ginseng through Biotransformation of Protopanaxadiol (PPD)-Type Ginsenosides to PPD.\nAbstract: Aging couples oxidative stress, inflammation, and leaky gut; ginsenosides are promising yet hobbled by poor conversion. We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis. Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection.\n\nID: 41968935\nTitle: The end of 'leaky gut': pathway-specific mechanistic approaches to barrier restoration.\nAbstract: For over 50\u200ayears, increased intestinal permeability has been associated with diverse inflammatory and systemic diseases. Yet the oversimplified concept of 'leaky gut' as a singular phenomenon has limited both mechanistic understanding and therapeutic development. It is now recognized that intestinal permeability occurs via two molecularly distinct, differentially regulated trans-tight junction pathways, while a tight junction-independent unrestricted pathway allows flux at sites of epithelial damage. The pore pathway is a high-conductance, size-selective and charge-selective flux route that mediates ion and water flux. Its upregulation can be either protective, as in infectious enterocolitis, or pathogenic, as in immune-mediated disease or, as shown recently, in sepsis. Myosin light chain kinase activation enhances flux across the leak pathway, a low-conductance macromolecular flux route, that promotes progression of immune-mediated diseases. Recently developed molecularly targeted, pathway-specific approaches to barrier restoration are effective and can outperform current therapies without the complications of broad immunosuppression. The evolving pathway-resolved framework transforms intestinal barrier biology from a descriptive science into mechanism-specific therapeutic approaches that have promise as independent agents and as complements to available immune-targeted therapies.\n\nID: 41968102\nTitle: Effects of gut barrier dysfunction during a viral respiratory disease challenge on immune function of feedlot beef calves.\nAbstract: Feedlot morbidity and mortality have increased in recent decades, driven in part by the prevalence of bovine respiratory disease (BRD). Research on gut barrier dysfunction (GBD) reveals similarities in predisposing factors and etiopathogenic mechanisms to BRD. This overlap suggests that GBD may serve as a predisposing factor, increasing susceptibility to BRD. To explore this connection, 15 Angus \u00d7 Holstein heifers (initial body weight\u2009=\u2009475\u2009\u00b1\u200912\u2009kg) were used in a randomized complete block design experiment to evaluate the effects of induced changes in intestinal permeability on immune responsiveness during a viral respiratory disease challenge. Treatments were control (CT; n\u2009=\u20097) or GBD (n\u2009=\u20098), where GBD heifers underwent a protocol to increase gut permeability using aspirin (100\u2009mg/kg of body weight every 12\u2009h for 4 consecutive days). Daily dry matter intake and average daily vaginal temperature (DVT) were continuously recorded. After aspirin withdrawal, all heifers were inoculated with bovine herpesvirus-1. Complete blood count, cytokines, acute-phase proteins (APP), cortisol, and intestinal morphology were evaluated. Heifer was considered the experimental unit for all analyses. The statistical model included the fixed effect of treatment and hour/day and the resultant interactions, run and heifer (treatment) were used as random effects, and hour or day was the term for all repeated statements, and heifer (treatment) was the subject. Aspirin administration increased gut permeability in GBD heifers, as evidenced by greater plasma Chromium-EDTA recovery (P\u2009=\u20090.02) and increased lipopolysaccharide-binding protein concentration (treatment \u00d7 hour; P\u2009<\u20090.01) early in the disease challenge. Compared to CT, GBD heifers tended to exhibit decreased DVT (P\u2009=\u20090.10) and haptoglobin concentration (treatment \u00d7 hour; P\u2009=\u20090.06) by the end of the disease challenge. No significant differences were observed in serum amyloid A, interleukin-6, tumor necrosis factor-\u03b1, interleukin-10, or cortisol concentration (P\u2009\u2265\u20090.20). A tendency for decreased white blood cell (P\u2009=\u20090.08) and lymphocyte counts (treatment \u00d7 hour; P\u2009=\u20090.08) in GBD heifers was observed. There were no effects of treatments on intestinal morphology (P\u2009\u2265\u20090.16). These findings suggest that increased gut permeability influences immune responses by reducing the febrile response and decreasing the production of some APP. Greater emphasis on gut health could improve disease outcomes in BRD management. Death loss associated with bovine respiratory disease (BRD) has continued to rise in recent decades, and as such, new approaches should be sought to mitigate BRD. Research suggests that the predisposing factors of gut barrier dysfunction (GBD) are like BRD in that they can both be triggered and aggravated by stress events, thus, they may occur simultaneously. GBD describes a disease state in the gastrointestinal tract that increases the exposure of blood circulation to microorganisms that naturally reside in the small intestine, resulting in inflammation. Gut health may affect disease outcomes because the gastrointestinal barrier is the body\u2019s largest immune organ, and supporting the immune response imposes a significant energetic cost. This energetic burden that GBD imposes on the body should be considered in terms of its ability to affect overall health outcomes. In this experiment, heifers were (GBD group) or were not (control group) subjected to a protocol that induced GBD. All heifers were then subjected to a respiratory disease challenge, and important indicators of the immune response were measured. Heifers with increased gut permeability exhibited a decreased febrile response, which may suggest a less robust early immune activation, as fever is an important part of the normal response to infection. These heifers also displayed altered acute\u2011phase protein production, which may influence how efficiently cattle can control and recover from infection. These results suggest that gut health may play a significant role in overall cattle immunity and should be given greater consideration in the effort to improve disease outcomes.\n\nID: 41936926\nTitle: \u03b2-Hydroxybutyrate modulates intestinal barrier function and visceral sensitivity via a brain AMPK-orexin pathway recruiting histamine H1 receptors, basal forebrain cholinergic neurons, adenosine A2B receptors, and vagal output in rats.\nAbstract: Irritable bowel syndrome (IBS) is characterized by chronic abdominal pain and altered bowel habits, with visceral hypersensitivity and impaired intestinal barrier function as key pathophysiological features. Although peripheral determinants of barrier dysfunction have been studied, the contribution of central regulatory mechanisms remains unclear. \u03b2-Hydroxybutyrate (BHB), a major ketone body elevated during fasting, exhibits anti-inflammatory and barrier-protective effects peripherally, but its central actions are unknown. Here, we investigated whether BHB acts within the brain to regulate intestinal barrier function and visceral sensitivity using an LPS-induced rat model. Intracisternal BHB dose-dependently attenuated LPS-induced colonic hyperpermeability and visceral hypersensitivity, whereas an equivalent subcutaneous dose was ineffective, indicating a centrally mediated effect. The protection conferred by intracisternal BHB was abolished by vagotomy and by pharmacological inhibition of brain AMPK, orexin 1 receptors, histamine H1 receptors, basal forebrain cholinergic neurons (BFCNs), or adenosine A2B receptors. Peripheral BHB also ameliorated barrier dysfunction and visceral hypersensitivity; however, these effects persisted after vagotomy while remaining sensitive to central pharmacological blockade, suggesting engagement of shared brain signaling modules together with vagus-nonobligatory components. Collectively, these findings demonstrate that BHB regulates intestinal barrier function and visceral sensitivity through both central and peripheral mechanisms. Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways. BHB thus emerges as a neuro-metabolic signal modulating core gut-brain interaction processes and represents a promising therapeutic target for leaky gut-associated disorders, particularly IBS.\n\nID: 41932000\nTitle: Rhubarb ameliorates ischemic stroke-induced tryptophan-kynurenine metabolic reprogramming and neuroinflammation via modulation of the IDO-1/TREM-1 pathway.\nAbstract: Ischemic stroke (IS) elicits intertwined metabolic derangements and neuroinflammatory responses that propagate pathogenic cascades. Rhubarb (RR) is widely applied to treat IS in the clinic. However, its underlying pharmacological mechanisms remain incompletely elucidated. To dissect the mechanism and pharmacological basis of RR's ability to ameliorate IS from the side of modulating tryptophan-kynurenine (TRP-KYN) metabolism and neuroinflammation. An embolic middle cerebral artery occlusion (MCAO) model was employed in rats to simulate human IS. Neurological deficit scores, hematoxylin-eosin, 2,3,5-triphenyltetrazolium chloride, alcian blue-periodic acid-Schiff staining, Western blotting, targeted metabolomics, immunofluorescence, and enzyme-linked immunosorbent assay were utilized to evaluate the efficacy of RR against cerebral ischemic injury, gut permeability, TRP-KYN metabolism levels, and neuroinflammation. Surface plasmon resonance and cell-based assays were further utilized to screen and validate potential bioactive ingredients of RR for the treatment of IS. In addition to mitigating cerebral ischemic damage, RR treatment substantially restored intestinal barrier function in IS rats by reducing leaky gut biomarkers, ameliorating histopathological alterations, and upregulating colonic tight junction proteins. Moreover, RR modulated TRP-KYN metabolism, concomitant with regulated expression and enzymatic activity of indoleamine 2,3-dioxygenase 1 (IDO-1) and the triggering receptor expressed on myeloid cells-1 (TREM-1) levels in both colon tissue and serum. Within the central nervous system, RR attenuated neuroinflammation triggered by MCAO through orchestrating microglial polarization and cytokine levels, accompanied by suppression of the TREM-1-mediated inflammatory signaling cascade. Chrysophanol 8-O-\u03b2-d-glucoside, rutinum, lindleyin, and (-)-catechin gallate from RR were identified as potential IDO-1 inhibitors, while rhein, lindleyin, methyl gallate, and chrysophanol 8-O-\u03b2-d-glucoside were identified as potential TREM-1 inhibitors, capable of attenuating the overexpression of IDO-1 and TREM-1 or TREM-1 and NOD-like receptor protein 3 (NLRP3). This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation. These effects are attributed to its bioactive components, including rutinum, chrysophanol 8-O-\u03b2-d-glucoside, lindleyin, (-)-catechin gallate, rhein, and methyl gallate.\n\nID: 41885697\nTitle: Beneficial effect of omega-3 fatty acids supplementation on leaky gut, inflammation and oxidative stress in propionic acid-induced autism in aged rats.\nAbstract: This study examined the effects of omega-3 fatty acids supplementation on gut barrier integrity, systemic inflammation, neurotrans-mission and oxidative stress, in an aged rat model of propionic acid (PPA)-induced neurotoxicity. Twenty-four aged male rats were divided into four groups: control, omega-3, PPA and PPA + omega-3. Serum cytokines, tight-junction proteins (TJP1), dopamine, serotonin, short-chain fatty acids (SCFAs), oxidative stress markers, and histopathology of the brain and small intestine were evaluated. PPA exposure significantly increased tumour necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-6 (IL-6) and reduced TJP1 expression, confirming gut barrier disruption and systemic inflammation. Omega-3 fatty acids supplementation selectively reduced IL-6 but did not reverse PPA-induced TNF-\u03b1 elevation or oxidative stress. CLDN2 expression increased in PPA + omega-3 rats, suggesting a compensatory but incomplete barrier response. Dopamine, serotonin, and SCFA levels showed upward trends with supplementation but were not statistically significant. Histological analysis demonstrated partial preservation of neuronal and intestinal structure in the PPA + omega-3 group. Overall, omega-3 fatty acids exerted modest anti-inflammatory effects but failed to fully restore oxidative balance or barrier integrity in aged rats, suggesting that omega-3 fatty acids may be more effective as a preventive rather than restorative intervention in ageing-related gut-brain axis disruption.\n\nID: 41703973\nTitle: Impaired Intestinal Function Among Indigenous Shuar Children of Amazonian Ecuador: Evidence From Lactulose:Mannitol Tests of Absorption and Permeability.\nAbstract: Intestinal function is an important but often overlooked aspect of human biological variation, with the intestines serving as both a barrier against external pathogens/contaminants and the primary conduit of nutrient extraction from food. Impaired intestinal function among children is viewed as a key contributor to growth faltering globally. However, few studies have investigated children's intestinal function in rural settings or beyond infancy. To address this limitation, we conducted a pilot study to describe the intestinal function of school-age Indigenous Shuar children of Amazonian Ecuador and to assess the feasibility of implementing the widely utilized lactulose:mannitol (L:M) test of absorption and permeability with this group. The urinary L:M test was performed with 23 rural-living Shuar children aged 4-12\u2009years. Ultra-performance liquid chromatograph-high-resolution mass spectrometry was used to determine L:M ratios, lactulose recovery, and mannitol recovery. Age and sex patterns were investigated using linear regression models. Children's mean L:M ratio was 0.33\u2009\u00b1\u20090.32, a ratio comparable to values reported for children in other low- and middle-income settings. 35%-91% of children were categorized as having impaired intestinal function using common cut-off values. Children's lactulose (0.14%\u2009\u00b1\u20090.17%) and mannitol (2.60%\u2009\u00b1\u20092.22%) recoveries did not differ by sex but increased with age (p\u2009<\u20090.05) and indicated diminished intestinal absorptive capacity and increased permeability. Intestinal function appears to be considerably impaired among school-age Shuar children living in a low-resource, rural setting. Children living in unsanitary, non-industrialized contexts may routinely experience intestinal permeability-related immune activation and malabsorption-related energy/nutrient loss. More research is needed to explore the breadth of global variation in children's intestinal function and to investigate its many evolutionary and public health implications.\n\nID: 41663400\nTitle: Phytic acid (InsP6) activates HDAC3 epigenetic axis to maintain intestinal barrier function.\nAbstract: HDAC inhibition shows promise in cancer treatment but pan-HDAC inhibitors cause gastrointestinal issues in 48% of patients. Understanding HDAC activation mechanisms is crucial to treating diverse diseases beyond cancer. Our study reveals that inositol polyphosphate multikinase (IPMK) and inositol hexakisphosphate (InsP6 or phytic acid), enriched in vegan diets, play essential roles in activating the HDAC3 epigenetic axis and maintaining intestinal barrier integrity. IPMK binds to HDAC3 and drives InsP6 synthesis, which selectively activates HDAC3 at a 10\u2009nM concentration by recruiting the DAD domain of its corepressor protein. IPMK deletion diminishes HDAC3 activation, leading to histone hyperacetylation and MMP gene transcription that compromise intestinal barrier integrity. InsP6 treatment is sufficient to rescue these effects. In inflammatory bowel disease, diminished IPMK levels exacerbate intestinal permeability, while oral InsP6 treatment mitigates leaky gut effects by restoring the HDAC3 epigenetic axis, highlighting the clinical significance of the IPMK-HDAC3 pathway and the therapeutic potential of phytic acid.\n\nID: 41572438\nTitle: Functional shotgun metagenomic insights into gut microbial pathway and enzyme disruptions linking metabolism, affect, cognition, and suicidal ideation in major depressive disorder.\nAbstract: Major depression (MDD) is linked to neuro-immune, metabolic, and oxidative stress (NIMETOX) pathways. The gut microbiome may contribute to these pathways via leaky gut and immune\u2013metabolic processes. To identify gut microbial alterations in MDD and to quantify functional pathways and enzyme gene families and integrate these with the clinical phenome and immune\u2013metabolic biomarkers of MDD. Shotgun metagenomics with taxonomic profiling was performed in MDD versus controls using MetaPhlAn v4.0.6, and functional profiling was conducted using HUMAnN v3.9, aligning microbial reads to species-specific pangenomes (Bowtie2 v2.5.4) followed by alignment to the UniRef90 v201901 protein database (DIAMOND v2.1.9). Gut microbiome diversity, both species richness and evenness, is quite similar between MDD and controls. The top enriched taxa in the multivariate discriminant profile of MDD reflect gut dysbiosis associated with leaky gut and NIMETOX mechanisms, that is, Ruminococcus gnavus, Veillonella rogosaem, and Anaerobutyricum hallii. The top four protective taxa enriched in controls indicate an anti-inflammatory ecosystem and microbiome resilience, that is, Vescimonas coprocola, Coprococcus, Faecalibacterium prausnitzii, and Faecalibacterium parasitized. Pathway analysis indicates loss of barrier protection, antioxidants, and short-chain fatty acids, and activation of NIMETOX pathways. The differential abundance of gene families suggests that there are metabolic distinctions between both groups, indicating aberrations in purine, sugar, and protein metabolism. The gene and pathway scores explain a larger part of the variance in suicidal ideation, recurrence of illness, neurocognitive impairments, immune functions, and atherogenicity. The gut microbiome changes might contribute to activated peripheral NIMETOX pathways in MDD.\n\nID: 41530574\nTitle: The gut-kidney axis in pediatric acute kidney injury: a review of pathophysiological mechanisms and therapeutic frontiers.\nAbstract: Acute kidney injury (AKI) is a frequent and severe condition in hospitalized children, leading to significant morbidity, mortality, and long-term risk of chronic kidney disease. This review explores the gut-kidney axis, a concept describing the bidirectional relationship between the gut microbiome and kidney function, as a critical driver of pediatric AKI. In critically ill children, interventions such as broad-spectrum antibiotics and necessary nutritional support strategies (e.g., parenteral nutrition or fasting) can cause profound gut microbial imbalance (dysbiosis). This dysbiosis initiates a deleterious feedback loop, exacerbating kidney injury. Key mechanisms include the disruption of the intestinal barrier (leaky gut), which allows bacterial endotoxins to enter the bloodstream, triggering renal inflammation via Toll-like receptor 4 signaling. Concurrently, the dysbiotic gut increases production of directly nephrotoxic gut-derived uremic toxins, such as indoxyl sulfate and p-cresyl sulfate, while failing to produce protective anti-inflammatory metabolites like short-chain fatty acids. While therapies targeting the microbiome, such as probiotics, prebiotics, and fecal microbiota transplantation, are theoretically promising, their clinical use in pediatric AKI is unsupported by evidence and carries substantial risks, particularly iatrogenic infection. A significant knowledge gap exists due to a relative lack of pediatric-specific clinical research. The conclusion emphasizes an urgent need for longitudinal, multi-omics studies in children to understand this axis, identify functional biomarkers, and develop safe, targeted therapies to improve outcomes.\n\nID: 41511288\nTitle: Oxidative Stress-Microbiota-Epigenetics Crosstalk: A Missing Link Between Cognition and Social Behavior in Metabolic and Neuropsychiatric Disorders.\nAbstract: Oxidative stress (OS) reflects a pathologic imbalance between excessive production of reactive oxygen species (ROS) and insufficient antioxidant defenses. Growing evidence indicates that a healthy gut microbiota (GM) is essential for regulating redox homeostasis, whereas gut dysbiosis contributes to elevated ROS levels and oxidative damage in DNA, lipids, and proteins. This redox disequilibrium initiates a cascade of cellular disturbances-including synaptic dysfunction, altered receptor activity, excitotoxicity, mitochondrial disruption, and chronic neuroinflammation-that can, in turn, impair cognitive and social functioning in metabolic and neuropsychiatric disorders via epigenetic mechanisms. In this review, we synthesize current knowledge on (1) how OS contributes to cognitive and social deficits through epigenetic dysregulation; (2) the role of disrupted one-carbon metabolism in epigenetically mediated neurological dysfunction; and (3) mechanistic links between leaky gut, OS, altered GM composition, and GM-derived epigenetic metabolites. We also highlight emerging microbiota-based therapeutic strategies capable of mitigating epigenetic abnormalities and improving cognitive and social outcomes. Understanding the OS-microbiota-epigenetic interplay may uncover new targetable pathways for therapies aimed at restoring brain and behavioral health.\n\nID: 41254964\nTitle: The interrelationships between malnutrition and intestinal permeability in adults: a systematic review and critical appraisal of current evidence.\nAbstract: Malnutrition results from inadequate nutrient intake, assimilation or utilisation, negatively impacting clinical outcomes and quality of life. It likely compromises gut barrier integrity, increasing intestinal permeability (IP), which impairs nutrient absorption or utilisation and increases the risk of infections and inflammation. This systematic review aims to examine the current evidence on the association between malnutrition and IP, identifying existing research gaps. A systematic search was conducted on PubMed, Scopus and Web of Science up to June 2024. According to PECOS strategy, \u2018P\u2019 = malnourished individuals or at risk of malnutrition, assessed for intestinal permeability; \u2018E\u2019 = malnutrition or risk of malnutrition; \u2018C\u2019 = well-nourished individuals; \u2018O\u2019 = increased intestinal permeability; and \u2018S\u2019 = all study types. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist was followed, and Study Quality Assessment Tools (NIH) were used for methodological quality analysis. Sixteen studies met the inclusion criteria, with a moderate/high risk of bias. Malnourished individuals exhibited increased IP across various conditions (e.g. anorexia nervosa, cancer and liver cirrhosis) or setting (hospital and community). A wide heterogeneity was observed in malnutrition assessment tools, which consider different parameters such as body mass index, body weight loss and food intake. Similarly, diverse biomarkers/methods for assessing IP, including direct and indirect approaches, were used. Despite methodological heterogeneity, findings show an association between malnutrition and increased IP. Standardised research, including comprehensive biomarker panels, is needed to improve comparability, facilitating the development of targeted interventions for preventing malnutrition and managing its complications.\n\nID: 42543917\nTitle: Adaptation of White Adipocytes to Cooler Temperatures: Impacts on Energy Metabolism and Protein Acetylation.\nAbstract: Adipocytes throughout the body reside in distinct thermal environments. Visceral adipocytes within the body core are maintained near 37\u00b0C, whereas those in bone marrow, subcutaneous, and dermal depots occupy cooler regions within the peripheral shell. Although brown and beige adipocyte responses to cold stress are well characterized, much less is known about how white adipocytes adapt to moderately reduced temperatures below 37\u00b0C. Our recent work revealed that cultured adipocytes exposed to 31\u00b0C, a temperature representative of distal adipose regions, exhibit enhanced mitochondrial function, including increased substrate oxidation and ATP turnover, yet the mechanisms underlying this upregulation remain unclear. Here we show that adaptation to cool temperatures leads to a widespread decrease in protein acetylation in both undifferentiated and differentiated adipocytes, independent of nutrient status, and that this change is readily reversible upon rewarming. Subcellular fractionation and immunoblotting demonstrate that the hypoacetylation coincides with a compartment-specific enrichment of acetylated proteins within mitochondria, indicating selective remodeling of the mitochondrial acetylome. Transcriptomic and biochemical analyses reveal that these temperature-dependent changes occur without alterations in acetyltransferase or deacetylase expression, NAD+ concentration, or acetyl-CoA availability, suggesting regulation through alternative mechanisms affecting acetyl-CoA flux or enzyme activity. Integrative acetyl-proteomic and metabolomic profiling identifies mitochondrial enzymes, including serine hydroxymethyltransferase 2 (SHMT2) and propionyl-CoA carboxylase \u03b1 (PCCA), whose acetylation correlates closely with changes in associated metabolite pools. Together, these findings establish physiologically relevant cooling as a cell-autonomous regulator of mitochondrial protein acetylation and metabolic adaptation in adipocytes.\n\nID: 42543617\nTitle: N-Acetylcysteine, Dichloroacetate, and Metformin Restore Mitochondrial Homeostasis by Counteracting Oxidative Stress and Fusion-Fission Imbalance in Palmitic Acid-Induced Lipotoxicity.\nAbstract: Palmitic acid (PA)-driven lipotoxicity in skeletal muscle is associated with excessive reactive oxygen species (ROS) and disturbed mitochondrial dynamics. This study aimed to characterize PA-induced alterations in oxidative status and fusion-fission balance in C2C12 skeletal muscle cells and to test whether N-acetylcysteine (NAC), dichloroacetate (DCA), or metformin mitigate these changes. Differentiated C2C12 myotubes were exposed to PA under conditions detailed in the Methods. Intracellular ROS was quantified, antioxidant defenses were assessed by activities of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD), and mitochondrial dynamics were evaluated by expression of the fusion protein mitofusin 1 (MFN1) and the fission protein dynamin-related protein 1 (DRP1), together with morphological assessment of mitochondrial fragmentation. PA exposure increased ROS and was accompanied by decreases in CAT, GPx, and SOD activities. PA shifted mitochondrial dynamics toward fission, with reduced MFN1, elevated DRP1, and increased mitochondrial fragmentation. Co-treatment with NAC, DCA, or metformin attenuated PA-induced ROS accumulation, improved antioxidant enzyme activities relative to PA alone, and partially normalized MFN1 and DRP1 expression, with reduced fragmentation. In an in vitro C2C12 model, PA-induced lipotoxicity is associated with oxidative stress and a fusion-fission imbalance favoring mitochondrial fragmentation. NAC, DCA, and metformin mitigate these alterations and help preserve mitochondrial homeostasis. These findings support targeting oxidative stress and mitochondrial dynamics as a potential approach to counteract mitochondrial dysfunction under lipotoxic conditions.\n\nID: 42543445\nTitle: The potential therapeutic effect of quercetin on mitochondrial dysfunction in hepatorenal toxicity induced by aluminum chloride in an experimental rat model.\nAbstract: Aluminum is a xenobiotic element known to induce hepatorenal toxicity through mechanisms involving mitochondrial dysfunction, oxidative stress, and inflammation. Quercetin, a dietary flavonoid with potent antioxidant and anti-inflammatory properties, has shown promise as a therapeutic agent. This study aimed to evaluate the potential therapeutic effects of quercetin against aluminum chloride (AlCl\u2083)-induced hepatorenal toxicity and mitochondrial dysfunction in rats. Hepatorenal toxicity was induced by oral administration of hydrated aluminum chloride (75 mg/kg body weight) daily for six weeks. Quercetin was administered intraperitoneally at a dose of 30 mg/kg body weight daily for four weeks. Biochemical assays, mitochondrial gene expression analysis, and histopathological examinations were conducted to assess the therapeutic effects. Quercetin significantly ameliorated lipid, protein, and DNA oxidation parameters (MDA, AOPPs and 8-OHdG respectively), reduced inflammation marker (TNF-\u03b1), and restored mitochondrial biogenesis markers, including PGC-1\u03b1, mtTFA and mitochondrial DNA copy number (mtDNA-CN). In addition, Quercetin significantly decreased TNF-\u03b1 and increased PGC-1\u03b1 contents at protein levels. Histopathological findings corroborated these results, demonstrating that quercetin improved liver and kidney architecture. These findings suggest that quercetin may serve as a potential therapeutic agent for aluminum-induced hepatorenal toxicity.\n\nID: 42543341\nTitle: [Psoralen promotes osteogenic differentiation of MC3T3-E1 cells by regulating mitophagy via PINK1/Parkin pathway].\nAbstract: This study aims to investigate the protective effect of psoralen against hydrogen peroxide(H_2O_2)-induced oxidative stress injury in mouse cranial apical osteoblasts(MC3T3-E1) and explore its molecular mechanism in promoting osteogenic differentiation through PTEN-induced putative kinase 1(PINK1)/Parkin-mediated mitophagy regulation. An oxidative injury model in MC3T3-E1 cells was established with 200 \u03bcmol\u00b7L~(-1) H_2O_2. The experiment was conducted with four groups: normal, model, psoralen, and inhibitor groups. Cell viability and proliferation were assessed by the CCK-8 assay and EdU incorporation assay, respectively. Apoptosis was analyzed by Annexin V-FITC/PI double-staining flow cytometry. Mitochondrial membrane potential was evaluated with the JC-1 probe, and reactive oxygen species(ROS) levels were measured by the DCFH-DA probe. Early osteogenic differentiation markers and late mineralized nodule formation were observed by alkaline phosphatase(ALP) staining and alizarin S staining, respectively. Transmission electron microscopy was employed to examine mitochondrial ultrastructure changes. Immunofluorescence staining and Western blot were employed to determine the expression levels of PINK1, Parkin, p62, Runt-related transcription factor 2(Runx2), and Osterix. Molecular docking and 100 ns molecular dynamics simulations were conducted to validate the binding mode and stability of psoralen with PINK1. The results showed that psoralen ameliorated H_2O_2-induced cell damage in a concentration-dependent manner, with the optimal concentration being 80 \u03bcmol\u00b7L~(-1). Psoralen significantly promoted cell proliferation, upregulated the expression of Runx2, Osterix, PINK1, and Parkin, enhanced mitochondrial membrane potential, increased mitophagy levels and osteogenic differentiation capacity, and enlarged mineralized nodule area. Simultaneously, it inhibited apoptosis, reduced intracellular ROS content, and downregulated the expression of autophagy substrate p62. Molecular docking results showed that the binding energy between psoralen and PINK1 was-7.024 kcal\u00b7mol~(-1), and 100 ns molecular dynamics simulations further confirmed the structural stability of the formed complex with persistent hydrogen bond interactions. In conclusion, psoralen directly targets and activates the PINK1/Parkin pathway to mediate mitophagy, clear damaged mitochondria, improve the oxidative stress microenvironment, promote the expression of osteogenic marker proteins and mineralization, thereby enhancing osteogenic differentiation of MC3T3-E1 cells, providing a new target and candidate drug for the prevention and treatment of osteoporosis.\n\nID: 42543286\nTitle: [Inhibition of M1 polarization and inflammatory response in RAW264.7 macrophages by harpagide through PGC-1\u03b1-mediated improvement of mitochondrial function].\nAbstract: This study aimed to investigate whether harpagide can alleviate lipopolysaccharide(LPS) and interferon-gamma(IFN-\u03b3)-induced M1 polarization and inflammatory response in RAW264.7 macrophages by regulating peroxisome proliferator-activated receptor gamma coactivator-1 alpha(PGC-1\u03b1) and improving mitochondrial function. The GEO dataset GSE183077 was used for bioinformatics analysis to identify differentially expressed genes(DEGs) of M1 and M0 macrophages, which was followed by Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses. The M1 macrophage model was established in RAW264.7 macrophages by stimulation with LPS and IFN-\u03b3. Cell counting kit-8(CCK-8) assays were used to evaluate cell viability and determine the optimal concentration of harpagide for treatment. The Griess assay was performed to measure nitric oxide(NO) levels. The mRNA expression levels of interleukin-6(IL-6), interleukin-1\u03b2(IL-1\u03b2), and tumor necrosis factor-\u03b1(TNF-\u03b1) were determined by real-time quantitative polymerase chain reaction(qRT-PCR). JC-1, Mito-Tracker, and Mito-SOX fluorescent probes were used to assess mitochondrial membrane potential, mitochondrial function, and mitochondrial reactive oxygen species(ROS) levels, respectively. Western blot analysis was conducted to detect the protein expression levels of PGC-1\u03b1, NOD-like receptor family pyrin domain containing 3(NLRP3), dynamin-related protein 1(DRP1), inducible nitric oxide synthase(iNOS), and TNF-\u03b1. Transcriptomic analysis revealed that inflammatory responses and mitochondrial fission-related biological processes were significantly activated during M1 macrophage polarization. In vitro experiments confirmed that, compared with the control group, the model group exhibited an increased NO level in cell culture supernatant, elevated mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, impaired mitochondrial function, decreased mitochondrial membrane potential, and elevated mitochondrial ROS levels. Meanwhile, PGC-1\u03b1 protein expression was reduced, whereas NLRP3, DRP1, iNOS, and TNF-\u03b1 protein levels were upregulated. Following harpagide treatment, these changes were reversed in a dose-dependent manner, namely decreased NO production and mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, improved mitochondrial function, restored mitochondrial membrane potential and mitochondrial ROS levels, significantly upregulated PGC-1\u03b1 expression, and decreased expression of NLRP3, DRP1, iNOS, and TNF-\u03b1. In conclusion, harpagide alleviates inflammatory responses probably by modulating mitochondrial fission in macrophages and inhibiting NLRP3 inflammasome activation via activating PGC-1\u03b1.\n\nID: 42535759\nTitle: Stable Isotope-Resolved Metabolomics in Elucidating Mitochondrial Metabolic Reprogramming and Therapeutic Targets.\nAbstract: Stable isotope-resolved metabolomics (SIRM) has emerged as a pivotal methodology for dissecting mitochondrial metabolic reprogramming and its connection to therapeutic targets. By combining isotopically labeled substrates with metabolic flux analysis (MFA), SIRM enables dynamic, quantitative tracking of carbon flux through mitochondrial pathways. This review focuses on three disease contexts where SIRM has provided transformative insights: cancer, neurodegenerative disorders (Alzheimer's and Parkinson's diseases), and metabolic syndrome (type 2 diabetes and non-alcoholic fatty liver disease). Recent applications have delineated reprogramming signatures, identified metabolic dependencies, and elucidated drug mechanisms. SIRM also facilitates therapeutic monitoring and resistance assessment, offering quantitative biomarkers for patient stratification. We summarize recent advances, technical challenges, AI-powered innovations, and future directions, providing a foundation for optimizing metabolism-targeted therapies.\n\nID: 42535404\nTitle: Anticancer effects of tangeretin associated with reactive oxygen species generation, mitochondrial dysfunction and apoptosis in CaSki cells.\nAbstract: Cervical cancer is the fourth most common cancer and the fourth leading cause of cancer\u2011related mortality among women worldwide. Tangeretin (TAN), a polymethoxylated flavonoid derived from citrus fruit peel, exhibits relatively high structural stability due to its methoxy groups and exerts anticancer effects in various malignancies, including lung, liver and breast cancer. However, to the best of our knowledge, the anticancer effects of TAN in cervical cancer remain insufficiently explored. The present study investigated the mechanisms underlying the anticancer effects of TAN on the CaSki cervical cancer cell line. Cell viability was evaluated using the EZ\u2011Cytox cell viability assay. The colony formation and cell cycle arrest assays demonstrated that TAN inhibited cell proliferation by inducing G1 phase arrest. The wound\u2011healing and Transwell migration assays demonstrated that TAN could reduce the migratory ability of CaSki cells, and the Annexin V/propidium iodide staining assay revealed that TAN increased the apoptotic cell population. Mitochondrial reactive oxygen species (ROS) were identified using MitoSOX\u2122 staining and the mitochondrial membrane potential (MMP) was detected using JC\u20111 staining. The findings of these assays suggested that TAN could increase mitochondrial ROS levels and decrease mitochondrial MMP in CaSki cells. Western blot analysis showed that TAN upregulated the protein expression levels of E\u2011cadherin and Bax. In addition, TAN restored the tumor suppressor protein p53. Collectively, these findings suggested that may exhibit anticancer activity in CaSki cells.\n\nID: 42534766\nTitle: Overaccumulation of miR-483-3p exerts acute toxic effects on ovarian granulosa cells by impairing cell proliferation, mitochondrial function, and METTL3-mediated m6A modification.\nAbstract: Diminished ovarian reserve (DOR) is a common cause of female infertility. Prior high-throughput sequencing showed specific follicular fluid exosomal miRNA profiles in DOR patients, implicating exosomal miRNAs in DOR pathogenesis. Using miRNA PCR arrays, we found miR-483-3p was significantly upregulated in DOR follicular fluid exosomes. Bioinformatics and experiments indicated METTL3 as a potential miR-483-3p target, suggesting excess miR-483-3p exerts cytotoxicity and suppresses METTL3-mediated N6-methyladenosine (m6A) modification. This study thus investigated miR-483-3p effects on METTL3 expression, m6A levels, cell proliferation, and mitochondrial function in ovarian granulosa cells (GCs). The targeting interaction between miR-483-3p and METTL3 was confirmed using a dual-luciferase reporter gene assay. qRT-PCR, immunofluorescence, Western blot, and Dot blot were used to evaluate the effects of miR-483-3p mimics, cyclophosphamide (CTX), and STM2457 on METTL3 protein expression and m6A modification levels in KGN cells. Additionally, Cell Counting Kit-8 (CCK-8) and 5-Ethynyl-2'-deoxyuridine (EdU) assays, along with mitochondrial membrane potential (MMP) measurements, were used to examine the impact of these treatments on KGN cell proliferation and mitochondrial function. miR-483-3p directly targeted the 3'\u00a0untranslated region (3'UTR) of METTL3, and its mimics significantly suppressed METTL3 gene expression. In contrast, CTX robustly promoted METTL3 gene expression, accompanied by a substantial elevation in global m6A levels. STM2457 treatment also showed a similar trend. But miR-483-3p overexpression modestly inhibited METTL3 protein and m6A levels. Regarding cellular phenotypes, miR-483-3p overexpression, CTX, and STM2457 all exerted significant inhibitory effects on KGN cells. All three treatments consistently suppressed the cell viability of KGN cells, reduced the EdU-positive cell ratio, and decreased MMP levels. This study provides preliminary evidence suggesting a specific regulatory interaction between miR-483-3p and METTL3. We demonstrate that aberrantly high expression of miR-483-3p significantly suppresses METTL3 mRNA levels but only moderately reduces METTL3 protein and m6A levels, suggesting the involvement of complex post-transcriptional regulatory mechanisms. Furthermore, overaccumulation of miR-483-3p markedly inhibits the proliferation of ovarian GCs and impairs their mitochondrial function. Further investigation into the role of the candidate miR-483-3p-METTL3-m6A axis in DOR will be conducted using in vivo models alongside an expanded cohort of clinical samples.\n\nID: 42533686\nTitle: Reactive Oxygen Species: Molecular Mechanisms, Cellular Targets, and Implications for Genomic Stability.\nAbstract: Reactive oxygen species (ROS) are highly reactive molecules generated through endogenous metabolic pathways and exogenous environmental exposures. While essential for physiological processes-including cell signaling, proliferation, differentiation, immune defense, and neurotransmission-dysregulated ROS production contributes to oxidative stress and widespread biomolecular damage. This review outlines the major enzymatic and non-enzymatic mechanisms of ROS formation, emphasizing mitochondrial electron leakage, NADPH oxidase activity, and metal-catalyzed reactions. It further explores the impact of cold exposure, physical exercise, nutritional imbalance, and aging on ROS levels through alterations in mitochondrial function, calcium signaling, and antioxidant defenses. While ROS are vital for certain biological activities, the article also emphasizes their destructive potential. Particular attention is given to the vulnerability of mitochondrial DNA (mtDNA) and nuclear DNA to hydroxyl radical attack, resulting in base modifications, sugar lesions, tandem lesions, and DNA-protein cross-links. These lesions disrupt replication fidelity, impair DNA repair, and promote mutagenesis, ultimately threatening genomic stability. Finally, apoptosis is described as being modulated by ROS in a dose-dependent manner through the intrinsic, extrinsic, and ER-stress pathways, with the central role of p53 in determining cell fate being highlighted. Collectively, this review integrates current knowledge on ROS generation, physiological functions, stress-induced dysregulation, and the molecular mechanisms underlying oxidative damage, offering a comprehensive perspective on their implications for genomic integrity and disease development.\n\nID: 42533549\nTitle: Doxorubicin-Induced Cytotoxicity in Adipose-Derived Stem Cells Is Associated With Altered SAPK/JNK Signaling.\nAbstract: Adipose-derived stem cells (ADSCs) are widely used in regenerative medicine, but their functionality declines under chemotherapeutic stress. Doxorubicin (Dox) is an effective anticancer agent known to induce long-term toxicity in healthy tissues. Increasing evidence suggests that Dox promotes cellular dysfunction, including apoptosis, promotion of oxidative stress, and premature senescence. The SAPK/JNK signaling pathway is implicated in stress responses and may contribute to Dox-induced aging in stem cells. However, its role in ADSC senescence and functional decline remains unclear. This study evaluated the effects of Dox on ADSC viability and aging-associated processes, with a focus on SAPK/JNK signaling. ADSCs exposed to 0.1-100\u2009\u03bcM Dox for 24\u2009h showed reduced mitochondrial activity and ATP levels at clinically relevant doses (5\u2009\u03bcM), along with disrupted cell cycle progression and cytoskeletal alterations. Dox induced both apoptosis and premature senescence and increased oxidative stress. These effects were accompanied by alterations in SAPK/JNK pathway expression. Overall, Dox promoted ADSC dysfunction, highlighting potential limitations in the therapeutic use of ADSCs during chemotherapy and emphasizing the need for protective strategies. Alterations in the SAPK/JNK signaling pathway were observed in response to Dox-induced stress, suggesting that this pathway may contribute to the cellular stress response. These findings suggest that the development of approaches to preserve ADSC function and mitigate Dox toxicity is critical for improving the safety and efficacy of regenerative medicine applications.\n\nID: 42530255\nTitle: The miR-339-5p/ACSL4 Pathway Drives Ferroptosis in Macrophages Exposed to Silica Nanoparticles.\nAbstract: The widespread application of silica nanoparticles (SiNPs) in industrial fields has raised increasing concerns regarding their potential biological toxicity. However, the cellular mechanisms underlying SiNPs-related injury remain incompletely understood. This study was designed to investigate whether ferroptosis contributes to SiNPs-mediated cytotoxicity in macrophages and to explore the potential regulatory role of microRNAs. RAW264.7 cells were exposed to SiNPs to establish an in vitro toxicity model. Mitochondrial ultrastructure and cellular uptake were examined. Ferroptosis-related markers, including antioxidant capacity, lipid peroxidation, ferrous iron accumulation, and the expression of glutathione peroxidase 4 (GPX4), acyl-CoA synthetase long-chain family member 4 (ACSL4), and cyclooxygenase-2 (COX2), were assessed. The involvement of apoptosis and necroptosis was evaluated using specific pathway inhibitors. Transcriptomic sequencing was performed to identify differentially expressed miRNAs, followed by functional validation through miR-339-5p mimic transfection, and the direct interaction between miR-339-5p and ACSL4 was verified by dual luciferase reporter assay. SiNPs were efficiently internalized by RAW264.7 cells and induced pronounced mitochondrial structural damage, characterized by mitochondrial shrinkage and loss of cristae. SiNPs exposure markedly impaired cellular antioxidant capacity and promoted the accumulation of lipid peroxides and intracellular Fe2+. This coincided with a reduction in GPX4 expression, whereas ACSL4 and COX2 levels increased. Ferroptosis was identified as the predominant mode of SiNPs-induced cytotoxicity, while apoptosis and necroptosis played minor roles. Transcriptomic analysis identified miR-339-5p as a potential regulator associated with ferroptosis-related pathways, and the dual luciferase reporter assay confirmed that miR-339-5p directly targets Acsl4. Overexpression of miR-339-5p significantly attenuated the ferroptosis response induced by SiNPs. SiNPs induce ferroptosis as the predominant mode of cell death in macrophages through mechanisms involving oxidative stress and lipid peroxidation. miR-339-5p acts as a negative regulator of this process by directly targeting ACSL4, alleviating ferroptotic injury and providing new insights into the molecular mechanisms underlying the toxicity of SiNPs.\n\nID: 42522403\nTitle: Minoxidil Sulfate Regulates JAK/STAT Signalling and Mitochondrial Function in Alopecia Areata.\nAbstract: Alopecia areata (AA) is an autoimmune hair disorder characterized by interferon-gamma (IFN-\u03b3)-driven inflammation and collapse of hair follicle immune privilege. Although Janus kinase (JAK) inhibitors are effective, incomplete or delayed responses remain common. Minoxidil is frequently combined with JAK inhibitors in clinical practice, yet its immunomodulatory mechanisms in AA are unclear. We investigated the effects of minoxidil sulfate (MXS) on inflammatory signalling, immune privilege-associated features and mitochondrial stress responses, and evaluated whether MXS enhances the anti-inflammatory effects of the JAK inhibitor baricitinib. Clinical observations of patients receiving combination therapy were descriptively assessed. Mechanistic studies were conducted in human outer root sheath (ORS) cells stimulated with IFN-\u03b3 and polyinosinic:polycytidylic acid to model the AA inflammatory microenvironment. Representative clinical observations suggested accelerated hair regrowth after addition of oral minoxidil to baricitinib. In inflamed ORS cells, MXS enhanced baricitinib-mediated suppression of STAT1 phosphorylation and IFN-\u03b3-inducible chemokines (CXCL9, CXCL10, CXCL11). MXS also exerted baricitinib-independent anti-inflammatory effects by inhibiting STAT1 and STAT3 activation. Furthermore, MXS reduced inflammatory induction of MHC class I expression and partially restored insulin-like growth factor-1 expression. MXS attenuated cytosolic and mitochondrial reactive oxygen species accumulation, mitochondrial DNA damage and loss of mitochondrial membrane potential, accompanied by suppression of NOX1 and NOX4 expression. These findings suggest that MXS modulates inflammatory signalling, preserves immune privilege-associated features and protects mitochondrial integrity, providing a mechanistic rationale for adjunctive use with JAK inhibitors without additional systemic immunosuppression.\n\nID: 42521674\nTitle: Mitochondrial quality control in health and disease: mechanisms and therapeutic targets.\nAbstract: Mitochondria are essential for cellular homeostasis, integrating various signals to control key cellular functions such as metabolism, apoptosis, inflammation, cell proliferation and redox balance. Given their multifaceted functions, it is not surprising that mitochondrial dysfunction has been implicated as a key contributor to the pathogenesis of numerous human diseases. Consequently, preserving mitochondrial integrity and functionality is vital for overall organismal health. Mitochondrial health is safeguarded by a sophisticated and tightly regulated network of quality control systems. These include mitochondrial proteostasis, which ensures proper protein folding and degradation; mitochondrial biogenesis, which governs the synthesis of new mitochondria; mitochondrial dynamics, encompassing fusion and fission processes; and mitophagy, the selective autophagic removal of damaged mitochondria. Additionally, these core systems are intricately connected to other crucial mitochondrial processes, such as the maintenance of mitochondrial DNA integrity, the regulation of cristae architecture, and the control of mitochondrial permeability transition, all of which are indispensable for optimal mitochondrial performance. Preclinical and clinical studies consistently demonstrate a strong link between impairments in these quality control mechanisms and both aging and the development of a wide spectrum of diseases. These include cancer, metabolic disorders, cardiovascular conditions, neurodegenerative diseases and autoimmune pathologies. In this review, we explore the different facets of mitochondrial quality control and discuss their implications in disease progression and aging. Furthermore, we highlight recent advances in interventions and therapies aimed at modulating mitochondrial quality control, providing an overview of their potential to mitigate disease burden and promote healthy aging.\n\nID: 42518000\nTitle: The fullerenol C60(OH)36 influence on the structural-dynamic and functional parameters of mitochondria.\nAbstract: Fullerenols, which possess antioxidants, anti-inflammatory, and neuroprotective properties, can affect mitochondria. The effect of fullerenol C\u2086\u2080(OH)\u2083\u2086 on the structural-dynamic and functional parameters of mitochondria, both isolated in vitro and in vivo in Wistar rats, was studied. It was found that fullerenol at a dose of 10\u00a0mg/kg reduced bioenergetic parameters of both glutamate-dependent and succinate-dependent intracellular respiration in vivo. In the in vitro model system, fullerenol at a dose of 0.2\u00a0mg/ml significantly decreased the oxygen consumption rates in all metabolic states, leading to a reduction in the Lardy and Chance respiratory control ratios and the P/O ratio. Conversely, at a dose of 0.1\u00a0\u00b5g/ml, fullerenols significantly increased these respiratory parameters. Fullerenols, both in vivo and in vitro, increased the viscosity of annular and total mitochondrial membrane lipids. They did not affect the polarity of total lipids but decreased the polarity of annular lipids. Fullerenols at high doses induced significant conformational changes in membrane proteins, increasing their immersion into the lipid matrix. Our results demonstrate that fullerenols modulate mitochondrial bioenergetics and membrane structural dynamics in a dose-dependent manner, which may have implications for understanding both the cytoprotective and potentially cytotoxic effects of these nanoparticles.\n\nID: 42517342\nTitle: XPO1-dependent nuclear export regulates NS3 localization and promotes DENV-2 replication through mitochondrial remodeling and interferon suppression.\nAbstract: Nucleocytoplasmic transport is essential for cellular homeostasis and is frequently exploited by viruses during infection. Although dengue virus (DENV) non-structural protein 3 (NS3) undergoes nuclear trafficking, the role of nuclear export pathways in its localization and in viral replication remains poorly understood. Here, we show that pharmacological inhibition of exportin 1 (XPO1) promotes the accumulation of DENV-2 NS3 in both the nucleus and mitochondria of infected Huh-7 cells. XPO1 inhibition also induces mitochondrial morphological alterations resembling those observed during DENV infection. Moreover, blockade of nuclear export enhances DENV-2 replication in interferon-stimulated cells by reducing type I interferon production, suggesting the establishment of a pro-viral cellular environment. Our findings reveal that XPO1-mediated nuclear export contributes to the regulation of NS3 localization and links nuclear export to mitochondrial remodeling and suppression of antiviral signaling during DENV infection.\n\nID: 42514364\nTitle: NAD Metabolism in Acute Myeloid Leukaemia: Biological Rationale and Therapeutic Opportunities.\nAbstract: Acute myeloid leukaemia (AML) exhibits profound metabolic plasticity that enables leukaemic cells to survive environmental stress, nutrient limitation, and therapeutic pressure, ultimately driving disease persistence and relapse. While genetic and epigenetic alterations have guided risk stratification and therapeutic development, accumulating evidence indicates that nutrient-dependent metabolic rewiring represents a critical and targetable vulnerability in AML. Nicotinamide adenine dinucleotide (NAD) is a central metabolic cofactor whose intracellular availability is tightly linked to dietary intake of its precursors, including tryptophan, niacin (vitamin B3), nicotinamide, and nicotinamide riboside. NAD supports redox balance, mitochondrial metabolism, DNA repair, and stress adaptation, processes that are particularly critical for leukaemic stem cell survival under therapeutic stress. Recent studies demonstrate that AML cells, including those resistant to venetoclax- and hypomethylating agent-based regimens, exhibit heightened dependence on the NAD salvage pathway mediated by nicotinamide phosphoribosyltransferase (NAMPT). Pharmacological inhibition of this pathway induces profound NAD depletion, mitochondrial dysfunction, and selective leukaemic cell death. In this review, we integrate nutritional biology with emerging translational evidence to examine NAD metabolism as a nutrient-regulated metabolic vulnerability in AML. We discuss dietary sources and systemic regulation of NAD, the role of NAD-dependent pathways in leukaemic persistence, the translational exploitation of NAD salvage dependency, and the emerging controversy surrounding NAD supplementation in cancer. Finally, we highlight key knowledge gaps and future directions at the interface of nutrition, metabolism, and therapy response in AML.\n\nID: 42511861\nTitle: The Molecular and Cellular Mechanisms of Melatonin: From Physiological Actions to Clinical Applications in Reproductive Medicine.\nAbstract: Melatonin has evolved from its classical role as a pineal-derived circadian regulator to a molecule increasingly recognized for its mitochondrial and cytoprotective functions. This review examines the molecular mechanisms and translational implications of melatonin within a mitochondria-centered framework, with particular emphasis on reproductive medicine. Available evidence suggests that melatonin may influence mitochondrial quality control (MQC) through multiple interconnected processes, including ROS regulation, mitochondrial dynamics, mitophagy, biogenesis, and mitochondrial inflammatory signaling. In mitochondria, melatonin can attenuate electron transport chain-derived oxidative stress through direct radical-scavenging reactions, antioxidant metabolite formation, and indirect activation of endogenous antioxidant systems. Experimental studies further suggest that melatonin may modulate Drp1-mediated fission, OPA1- and Mfn1/2-associated fusion, PINK1/Parkin-mediated mitophagy, and SIRT1/PGC-1\u03b1-related mitochondrial biogenesis. In reproductive medicine, melatonin has been investigated as a potential adjunctive strategy in assisted reproductive technology, endometriosis, and polycystic ovary syndrome. However, clinical evidence remains heterogeneous, and most human studies have evaluated reproductive or biochemical outcomes rather than direct MQC-related biomarkers. Therefore, although melatonin represents a promising mitochondria-targeted adjunct, standardized dosing strategies, tissue-level pharmacodynamic assessment, and validated mitochondrial biomarkers are needed to determine whether these mechanisms translate into reproducible clinical benefit.\n\nID: 42511758\nTitle: UCP1-Dependent Thermogenic Adipose Tissue in Human Disease: Adipose-Centered Mechanisms, Biomarker Limitations, and Translational Perspectives.\nAbstract: Uncoupling protein 1 (UCP1) is a mitochondrial inner-membrane carrier classically recognized as the molecular effector of non-shivering thermogenesis in brown adipose tissue. By dissipating the proton-motive force generated by oxidative phosphorylation, UCP1 converts stored chemical energy into heat and enables adaptive thermogenesis during cold exposure. The rediscovery of metabolically active brown adipose tissue (BAT) and inducible beige adipocytes in adult humans has renewed interest in UCP1-positive thermogenic adipose tissue as a regulator of systemic metabolism and a potential target for therapeutic modulation in obesity and cardiometabolic disease. Beyond thermogenesis, accumulating evidence indicates that UCP1-positive brown/beige adipocytes and thermogenic adipose tissue are involved in lipid and glucose metabolism, mitochondrial redox homeostasis, inflammatory remodeling, organ protection, and tumor-associated metabolic adaptation, mainly through adipocyte-autonomous mechanisms and adipose-organ communication. However, UCP1 biology is complex: BAT activity measured by imaging does not directly quantify UCP1 proton conductance, non-adipose UCP1 expression is often low and technically challenging to validate, local cell-autonomous UCP1 function in non-adipose tissues remains controversial, and UCP1-independent thermogenic pathways may compensate in selected contexts. In this review, we summarize the molecular and structural basis of UCP1 function, its regulation at transcriptional and post-transcriptional levels, and its biological roles in cellular and systemic homeostasis, with explicit distinction between direct adipocyte-autonomous UCP1 functions, indirect systemic effects mediated by thermogenic adipose tissue, and preliminary or incompletely validated evidence of local UCP1 activity in non-adipose cells. We further discuss the association of UCP1-positive thermogenic adipose tissue with obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease, kidney injury, liver disease, neurological disorders, and cancer. Finally, we evaluate UCP1-related thermogenic adipose tissue activity as a biomarker and therapeutic target, highlighting current limitations, safety concerns, and future directions for precision metabolic medicine.\n\nID: 42511691\nTitle: Mitochondrial Toxicology of Heavy Metals and Pesticides: Transport Systems, Mitochondrial Dysfunction and Permeability Transition.\nAbstract: Mitochondrial transport systems are essential regulators of cellular bioenergetics, calcium homeostasis, and metabolic signaling, and have emerged as critical targets of environmental toxicants. Although heavy metals and pesticides act through distinct primary mechanisms, increasing evidence indicates that they converge on a common network of mitochondrial dysfunction characterized by oxidative stress, impaired metabolite transport, calcium dyshomeostasis, and sensitization to mitochondrial permeability transition. This review provides an updated overview of the major mitochondrial transport systems involved in environmental toxicity, including the adenine nucleotide translocator (ANT), phosphate carrier (PiC), mitochondrial calcium uniporter (MCU), voltage-dependent anion channel (VDAC), and F1\u00b7Fo-ATP synthase (ATP synthase). We discuss their physiological roles, the molecular mechanisms by which heavy metals and pesticides disrupt their function, and the effects on oxidative phosphorylation, reactive oxygen species (ROS) generation, cardiolipin remodeling, and mitochondrial membrane integrity. Particular attention is devoted to the debate surrounding the molecular basis of mitochondrial permeability transition pore (mPTP) formation and to the concept that permeability transition represents the integrated outcome of cumulative mitochondrial stress rather than dysfunction of a single protein. Finally, we summarize emerging therapeutic strategies aimed at preserving mitochondrial transport function, limiting mitochondrial permeability transition, and attenuating downstream inflammatory signaling. Understanding these convergent mechanisms may facilitate the development of interventions to mitigate chronic diseases associated with environmental toxicant exposure.\n\nID: 42511672\nTitle: Disulfidptosis-Associated Neurotoxicity Induced by Cadmium Under an Environmentally Relevant Cadmium Exposure Scenario.\nAbstract: Cadmium (Cd) is a widespread environmental pollutant associated with neurotoxicity, but its underlying mechanisms remain unclear. Disulfidptosis is a regulated cell death driven by disulfide stress under conditions of impaired cellular reducing capacity. This study investigated the potential involvement of disulfidptosis-associated molecular alterations in Cd-induced neurotoxicity. Male Sprague Dawley (SD) rats were exposed to cadmium chloride (Low-Dose Group: CdCl2: 0.036 mg/kg bw; High-Dose Group: CdCl2: 3.6 mg/kg bw) by oral gavage for 30 days. Neurobehavioral performance was assessed using the open field test, elevated plus maze, and Morris water maze. Hippocampal ultrastructure, redox-related metabolites, and disulfidptosis-associated genes were analyzed. In addition, bioinformatics analysis was performed by integrating cadmium-related, neurodegenerative disease-related, and disulfidptosis-related genes. The results showed that high-dose Cd exposure impaired locomotor activity, increased anxiety-like behavior, and disrupted spatial learning and memory (p < 0.05), accompanied by mitochondrial damage in hippocampal neurons. Bioinformatics analysis identified seven overlapping genes and enrichment of ferroptosis and oxidative phosphorylation pathways. Biochemically, cadmium exposure significantly increased the NADP+/NADPH ratio ([Control: 1.07 \u00b1 0.044] vs. [High-dose: 3.80 \u00b1 0.059], p < 0.05) and decreased the GSH/GSSG ratio ([Control: 2.80 \u00b1 0.059] vs. [High-dose: 1.14 \u00b1 0.091], p < 0.05), indicating severe redox imbalance. At the molecular level, cadmium exposure upregulated SLC7A11 mRNA expression by 1.48 \u00b1 0.12-fold (p < 0.01) and SLC3A2 by 1.91 \u00b1 0.55-fold (p < 0.05), while downregulating NDUFS1 expression to 0.84 \u00b1 0.01-fold of control levels (p < 0.01) in hippocampal tissues. These findings suggest that high-dose Cd exposure induced neurotoxicity is associated with mitochondrial dysfunction, redox imbalance, and disulfidptosis-associated molecular alterations.\n\nID: 42525157\nTitle: Electroacupuncture confers neuroprotection against ischemic stroke via the DNA methylation-RhoGDI\u03b1 axis.\nAbstract: Electroacupuncture (EA) has emerged as a promising alternative therapy for ischemic brain injury, yet its underlying molecular mechanisms remain incompletely understood. This study investigated the neuroprotective effects and epigenetic mechanisms of EA in a mouse model of ischemic stroke. Cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in mice. EA was applied at Baihui (GV20) and left Zusanli (ST36) acupoints following surgery. Neurological deficits were assessed, infarct volume was measured by TTC staining, and neuronal damage was evaluated by Nissl staining. RhoGDI\u03b1 protein expression was determined by Western blot. Global DNA methylation was quantified by ELISA, and promoter-specific methylation of RhoGDI\u03b1 was examined by quantitative methylation-specific PCR (MSP), and mRNA expression of candidate DNA methyltransferases (DNMTs) and demethylases (TETs) was measured by qPCR. EA alleviated MCAO-induced brain injury, as reflected by improved neurological scores, reduced infarct volume, and attenuated neuronal loss. RhoGDI\u03b1 expression was downregulated after MCAO and restored by EA treatment. Pharmacological inhibition of RhoGDI\u03b1 abolished the neuroprotective effects of EA, underscoring its essential role in EA-mediated protection. Mechanistically, MCAO induced hypermethylation of the RhoGDI\u03b1 promoter, which was reversed by EA, leading to restoration of RhoGDI\u03b1 expression. Furthermore, co-administration of the DNA methylation inhibitor 5-Azacytidine synergistically enhanced the neuroprotective efficacy of EA. Our findings demonstrate that EA ameliorates ischemic brain injury in association with epigenetic regulation of RhoGDI\u03b1 via promoter demethylation. This study identifies RhoGDI\u03b1 as a key mediator of EA-induced neuroprotection and suggests that the DNA methylation-RhoGDI\u03b1 axis may represent a promising therapeutic target for ischemic stroke.\n\nID: 42474536\nTitle: From glycemic control to neuroprotection: alogliptin as a repurposed candidate for Huntington's disease.\nAbstract: Huntington's disease (HD) is a progressive, autosomal dominant neurodegenerative disorder characterized by motor dysfunction, cognitive decline, and psychiatric disturbances, for which no disease-modifying therapies are currently available. Emerging evidence implicates metabolic impairment, mitochondrial dysfunction, oxidative stress, and neuroinflammation as central contributors to HD pathogenesis, thereby highlighting novel avenues for therapeutic intervention beyond conventional strategies. In this context, drug repurposing has gained considerable attention as an efficient approach to accelerate therapeutic development. Alogliptin has multiple complementary mechanisms of action that exert neuroprotective effects through inhibition of DPP-4 to boost endogenous incretin signaling (especially GLP-1), inhibition of inflammatory pathways, inhibition of oxidative stress, preservation of mitochondrial function, and modulation of neuronal survival signaling. The review summarizes existing data on the contribution of the incretin signaling to neuroprotection and critically analyzes the mechanism through which alogliptin might regulate important pathological events in HD, such as apoptosis, oxidative stress, and neuroinflammation. Additionally, preclinical results and pharmacological properties in favor of its translational potential are presented, as well as the reflection on its clinical usage and additional research perspectives. Even though direct evidence in HD is not extensive, the overlap of metabolic and neurodegenerative pathways offers a strong argument to study. This review identifies alogliptin as a potent repurposable agent and the necessity to conduct specific experimental and clinical research to determine its effectiveness in refining symptoms and changing the disease course in HD. This narrative review critically evaluates the available experimental evidence supporting the repurposing potential of Alogliptin for HD.\n\nID: 42438036\nTitle: Protective Effect of Uric Acid on Rat Model of Irritable Bowel Syndrome Requires Brain-Gut Communication Through Vagal Cholinergic Pathways.\nAbstract: Uric acid (UA) is an endogenous antioxidant that protects against neuroinflammatory diseases. Although irritable bowel syndrome (IBS) is considered a disorder of gut-brain interaction, the role of UA in IBS remains unclear. An experimental rat model of IBS was induced using laser-induced shock waves (LISW) applied to the head. Hyperuricemia (HUA) was induced by intraperitoneal administration of inosine monophosphate and potassium oxonate. Visceral hypersensitivity was assessed by colorectal distension. Ileal mucosal permeability was measured using the Evans blue method. CRFR1 mRNA expression in the rectum, IL-10 and TGF-\u03b21 expression in the ileum, and IL-1\u03b1, IL-1\u03b2, and TNF expression in the medial prefrontal cortex (mPFC) and paraventricular nucleus (PVN) were quantified by qRT-PCR. Vagal involvement was assessed using subdiaphragmatic vagotomy or atropine treatment. LISW increased visceral hypersensitivity, ileal mucosal permeability, and rectal CRFR1 expression and reduced IL-10 expression in the ileum. HUA significantly ameliorated these changes. HUA was also associated with reduced IL-1\u03b2 expression in the mPFC and reduced IL-1\u03b1 and IL-1\u03b2 expression in the PVN in LISW-treated animals. Importantly, the ameliorative effects of HUA on visceral hypersensitivity were abolished by vagotomy or atropine treatment. Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain. The loss of HUA-induced suppression of visceral hypersensitivity after vagotomy or atropine treatment suggests the possible involvement of vagal and cholinergic brain-gut communication. Irritable bowel syndrome (IBS) is a common disorder in which people experience abdominal pain and bowel problems, often worsened by stress. We examined whether uric acid, a major endogenous antioxidant in the human body, can protect against changes seen in a rat model of IBS. An experimental model of IBS was created by applying laser\u2010induced shock waves to the head, leading to increased sensitivity to colorectal distension (a measure of visceral hypersensitivity), impaired barrier function of the lower small intestine, and reduced a protective anti\u2010inflammatory signal (IL\u201010) in the gut. Increasing blood uric acid levels reduced visceral hypersensitivity, improved the barrier function of the lower small intestine, and restored IL\u201010 levels. Importantly, the uric acid\u2013induced suppression of visceral hypersensitivity was lost when vagus nerve signaling was disrupted, indicating that vagal and cholinergic signaling is involved in this effect.\n\nID: 42416049\nTitle: GLP-1 receptor agonists in neurological diseases: mechanisms and therapeutic prospects from metabolism to neuroprotection.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are widely used metabolic therapies for type 2 diabetes and obesity, with well-established cardiovascular benefits. Beyond glycemic control, accumulating experimental and clinical evidence suggests that GLP-1RAs exert pleiotropic actions relevant to neurological diseases. Metabolic dysfunction, chronic inflammation, oxidative stress, mitochondrial impairment, and neurovascular injury represent convergent mechanisms that contribute to neurodegeneration, cerebrovascular pathology, and metabolism-related brain disorders. Notably, these processes overlap with pathways modulated by GLP-1 signaling across systemic and central compartments. GLP-1 receptors are expressed in neurons, glial cells, and components of the neurovascular unit, providing a biological basis for possible neurological effects. Preclinical studies suggest that GLP-1RAs can reduce neuroinflammation and oxidative stress, support mitochondrial function, and help maintain blood-brain barrier integrity. Clinical findings, however, remain inconsistent. Studies in Parkinson's disease have reported encouraging signals, but biomarker evidence for disease modification is still limited. In Alzheimer's disease, clinical trials have produced mixed or negative results. These differences may reflect disease stage, patient selection, drug-specific pharmacology, central nervous system exposure, endpoint sensitivity, and treatment duration. Overall, GLP-1RAs may influence neurological disease through metabolic, inflammatory, and vascular pathways, but their clinical role remains unsettled. Future studies should use biomarker-informed designs, prespecified neurological endpoints, appropriate drug selection, and sufficiently long follow-up to determine which patients and disease stages are most likely to benefit.\n\nID: 42411478\nTitle: Multi-Method Investigation of the Role of the PI3K/Akt Pathway in Sinomenine-Mediated Neuroprotection Against Acute Ischemic Stroke.\nAbstract: Effective neuroprotective therapies for acute ischemic stroke (AIS) remain limited due to the complex interplay between neuroinflammation and apoptosis. Sinomenine (Sino), a bioactive alkaloid derived from Sinomenium acutum, exhibits anti-inflammatory and anti-apoptotic activities; however, its molecular targets and mechanisms in AIS remain unclear. This study aimed to identify potential targets and key pathways of Sino and validate its neuroprotective effects in AIS. A combined approach integrating network pharmacology, Mendelian randomization (MR), molecular docking, and in vivo validation was adopted. Potential targets of Sino and ischemic stroke were identified using public databases. Overlapping targets were analyzed through protein-protein interaction network construction and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Sprague-Dawley rats were randomly assigned to four groups, and a middle cerebral artery occlusion/reperfusion (MCAO/R) model was established (n = 12 per group): Sham, MCAO/R, Sino (20 mg/kg), and Sino +LY294002 (LY, 10 mg/kg). Sino and Sino + LY were administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Sham and MCAO groups were given the same amount of physiological saline undergoing the same procedures. Sino was administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Neurological deficits, infarct volume, neuronal injury, apoptosis, activation of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway, and inflammatory responses were assessed using behavioral tests, 2,3,5-Triphenyltetrazolium chloride (TTC)/Nissl/Terminal deoxynucleotidyl transferase dUTP Nick End Labeling (TUNEL) staining, Western blotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA). Twelve overlapping targets between Sino and ischemic stroke were identified, with Akt1 recognized as a central hub. Enrichment analysis highlighted the PI3K/Akt pathway as a critical signaling axis, while MR analysis indicated a nominal association between Akt1 and ischemic stroke. Molecular docking predicted stable binding between Sino and Akt1. In MCAO/R rats, Sino significantly improved neurological function, reduced infarct volumes, attenuated neuronal apoptosis, and increased neuronal survival. Mechanistically, Sino increased the p-PI3K/PI3K and p-Akt/Akt ratios, upregulated Bcl-2 expression, and decreased the expression of Bax, cleaved caspase-3, ionized calcium-binding adapter molecule 1 (Iba1), inducible nitric oxide synthase (iNOS), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1). These beneficial effects were notably attenuated by LY. This study establishes PI3K/Akt as a functionally necessary mediator of Sino's neuroprotection against cerebral ischemia/reperfusion injury. The incomplete LY reversal indicates multi-target activity, supporting Sino's development as an adjunctive therapeutic candidate for ischemic stroke.\n\nID: 42401758\nTitle: Mitochondrial insufficiencies and neuroprotection in glaucoma.\nAbstract: Antihypertensive management has long been the mainstay of treatment for glaucoma. Despite contemporary treatments, many patients still experience disease progression, with some ultimately losing vision. The purpose of this review is to demonstrate how derangements in mitochondrial biology underpin the pathophysiology of glaucoma, and to explore emerging therapeutic options. Literature searches were performed using multiple databases, aiming to identify recent developments in the scientific knowledge surrounding mitochondrial biology and glaucoma. Key words used in the primary literature search included combinations of \"glaucoma\", \"mitochondria\", \"oxidative stress\", \"metabolism\", \"inflammation\", \"transport\" and \"genetics\". Additional database searches were performed to further explore specific details identified in the primary search. Recent research points to mitochondrial insufficiencies as a primary culprit in the pathophysiology of glaucoma. Dysfunction of mitochondria occurs in a multitude of ways, and is an integral component of neuroinflammation, metabolic compromise, and disruption of axonal transport. This in part results from accumulated genetic factors, leading to generation of superoxides that damage retinal ganglion cells resulting in neurodegeneration of the optic nerve. Defects in mitochondrial biology among a range of ocular cell types contribute to the progression of glaucoma. With this understanding, emerging treatments targeting mitochondria, including gene therapies, tunneling nanotubules, and pharmacotherapeutics which enhance mitochondrial function and reduce oxidative stress, are likely the future of glaucoma management. By targeting mitochondrial insufficiencies as a root cause of glaucoma in addition to managing intraocular pressure, this new approach offers hope for preventing vision loss and potentially curing glaucoma.\n\nID: 42398271\nTitle: Inhibiting 15-PGDH restores redox homeostasis and confers neuroprotection in Parkinson's disease.\nAbstract: The prostaglandin- and autocoid-degrading enzyme 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is shown here to be pathologically elevated in Parkinson's disease (PD) patients and mouse models of PD in the substantia nigra, the region of the brain where dopaminergic neurons are lost in PD. Inhibiting 15-PGDH by pharmacologic blockade or partial genetic reduction restores redox homeostasis and mitigates microglial and astrocyte activation, dopaminergic neuron loss, and motor impairment across three mouse models of PD. These models included systemic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), intranigral lipopolysaccharide (LPS), and intrastriatal AAV-\u03b1-synuclein with intra-ventral tegmental area \u03b1-synuclein preformed fibrils (PFFs). The neuroprotective efficacy of 15-PGDH inhibition in PD is shown to be mediated by downregulation of the dopaminergic neuronal cell death mediator lipocalin-2 (Lcn2), the pro-inflammatory cytokine interleukin-1\u03b2, the reactive oxygen generator Cybb/Nox2, and oxidative tissue damage. Mechanistically, in vitro exposure of BV2 microglia to LPS recapitulates induction of Lcn2, Cybb/N OX2 and superoxide, and all three of these effects are reversed by co-treating with prostaglandin E2 (PGE2), the prototypical degradation substrate of 15-PGDH. With a 15-PGDH inhibitor (MF-300) currently in human clinical trials for peripheral indications, these findings have translational relevance for PD.\n\nID: 42341848\nTitle: BACH1 inhibition confers neuroprotection after subarachnoid hemorrhage through activation of the Nrf2 signaling pathway.\nAbstract: Subarachnoid hemorrhage (SAH) remains one of the most severe forms of stroke, yet effective therapeutic options remain limited. The BTB domain and CNC homolog 1 (BACH1), a transcription factor widely distributed across mammalian tissues, has been implicated in regulating diverse cellular functions. Nevertheless, its role in early brain injury after SAH remains incompletely understood. In this study, we found that BACH1 expression rose rapidly and peaked at 24\u202fh after SAH. Both neurons and microglia exhibited detectable BACH1 expression. Silencing BACH1 with siRNA markedly alleviated neuroinflammation and oxidative stress, and improved neurological performance. Additionally, BACH1 suppression shifted microglial phenotypes by diminishing the M1 response and enhancing M2 polarization. Further analysis revealed that inhibiting BACH1 activated the Nrf2-dependent pathway, whereas Nrf2 depletion with ML385 diminished the protective effects associated with BACH1 knockdown. Collectively, these results identify BACH1 as a promising candidate for alleviating brain damage associated with SAH.\n\nID: 42336160\nTitle: YTHDF1-modified neural stem cells confer neuroprotection and promote functional recovery following traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) is a significant contributor to global morbidity and mortality, with limited effective treatment options available. Neural stem cells (NSCs) have shown great potential in the treatment of TBI. However, the relatively low differentiation rate of neurons largely hinders the therapeutic efficacy of brain tissue repair. Here, we found that following TBI, the expression level of YTHDF1 in the hippocampus significantly increased and then decreased. Previous reports have also indicated that YTHDF1 mRNA is preferentially expressed in the mouse hippocampus, a key region involved in spatial learning and memory. Subsequently, we overexpressed or knocked down YTHDF1 in NSCs, and the results demonstrated that YTHDF1 promoted NSC proliferation and neuronal differentiation. In vitro, neuronal injury was induced by H2O2, and co-cultured with YTHDF1-modified NSCs to assess neuronal cell viability, apoptosis, and oxidative stress biomarkers, including the activities of superoxide dismutase (SOD) and catalase (CAT). YTHDF1-modified NSCs significantly reduced neuronal apoptosis and lowered oxidative stress levels. The expression of YTHDF1 in the hippocampus of TBI mice could rescue sensory, motor, and cognitive deficits, promoting neuronal survival. Mechanistically, YTHDF1 may be transcriptionally regulated by MYCN, and exert neuroprotective effects through the PI3K/AKT signaling pathway.\n\nID: 42320726\nTitle: Molecular crosstalk between MAPK signaling and neuroprotective pathways in Parkinson's disease: from pathogenesis to therapeutic potential.\nAbstract: Mitogen-activated protein kinase (MAPK) signaling is increasingly recognized as a central regulator in the pathogenesis of Parkinson's disease (PD). PD is a chronic neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc), driven by a complex interplay of mitochondrial dysfunction, oxidative stress, and neuroinflammation. While basal MAPK activity is essential for neuroprotection and neuronal growth, its overactivation, specifically via the JNK and p38 cascades, accelerates neurodegeneration. This review explores the molecular landscape of MAPK signaling, detailing how its dysregulation promotes the accumulation of alpha-synuclein and the activation of microglia. Furthermore, it highlights critical crosstalk between MAPK and other vital pathways, including the inhibition of the neuroprotective PI3K/AKT and PP2A pathways and the detrimental activation of GSK-3\u03b2 and PTEN signaling. Preclinical evidence strongly supports the use of MAPK inhibitors to mitigate dopaminergic neurotoxicity and reduce proinflammatory cytokine release. Despite promising results in experimental models and the development of highly selective inhibitors, clinical translation remains challenging due to potential systemic toxicities. This manuscript provides a comprehensive synthesis of mounting and mooting evidence, positioning MAPK inhibition as a potent, albeit complex, adjuvant strategy for delaying the onset and progression of PD neuropathology.\n\nID: 42313682\nTitle: Atypical Tetracyclines Promote Longevity and Ferroptotic Neuroprotection via Translation Attenuation.\nAbstract: Reducing protein synthesis extends lifespan across taxa, but pharmacological strategies to safely attenuate translation remain limited. Tetracyclines are clinically used antibiotics long observed to exert beneficial effects in age-associated diseases and extend lifespan in model organisms, though the underlying mechanisms remain unclear. Here, we systematically profiled commercially available tetracyclines and show that translation attenuation is a general property of the tetracycline class. Importantly, we identify the atypical tetracyclines 4-epiminocycline and 12-aminominocycline, which attenuate translation independently of antibiotic activity and integrated stress response (ISR) activation. These compounds extend lifespan in C. elegans, attenuate translation in human induced neurons, reduce hippocampal protein synthesis in\u00a0vivo, and protect neurons from ferroptotic stress. Together, our results demonstrate that pharmacological attenuation of translation is sufficient to promote longevity and establish translation attenuation as a druggable longevity mechanism in mammals.\n\nID: 42307855\nTitle: Therapeutic Effects of Zhilong Huoxue Tongyu Capsule on Oxidative Stress and Neuroprotection in a Rat Model of Intracerebral Hemorrhage.\nAbstract: The purpose of this study is to investigate the mechanism of Zhilong Huoxue Tongyu (ZL) capsule on the treatment of intracerebral hemorrhage (ICH).\u00a0In this study, ICH model was established to assess the neuroprotective efficacy of ZL capsule. The ICH-induced neurological deficits were analyzed by behavioral studies including Zea-Longa score, Neurological Severity Score, Open filed test, Y-maze test, Morris water maze, Rotarod test and pathological staining such as HE staining and Nissl staining. Perls staining was used to measure iron deposition after ICH. Malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) assay kits were performed to measure the level of lipid peroxide after ICH. The levels of oxidative stress-related targets were verified by quantitative real-time PCR and western blot.\u00a0This study demonstrated that ZL capsule treatment significantly reduced ICH-induced neurological deficits after ICH, improved the memory learning functions of rats and attenuated ICH\u2011Induced neuron damage in rats. After ICH, oxidative stress in brain tissue increased and ZL capsule could alleviate the pathological state of oxidative stress. The SOD and GSH activities were dramatically increased after the treatment of ZL capsule compared with the Ns group, while the content of MDA was markedly decreased after treatment with ZL capsule compared with Ns group. After ICH, the SLC40A1, SLC7A11, SESN2 and GPX4 mRNA in brain tissue increased, and the NOX4 and TFR1 mRNA in brain tissue decreased after the treatment of ZL capsule. Proteomics analysis also confirmed these results.\u00a0Our data suggested that ZL capsule showed a neuroprotective function after ICH and alleviated ICH induced neurological deficits in rats. The possible mechanism may be that ZL capsule inhibits iron deposition and lipid peroxidation, lessening oxidative stress in brain tissue. This study offers new insights into how the ZL capsule affects ICH at the molecular level and could be conducive to developing therapeutic drugs for ICH and traditional Chinese medicine.\n\nID: 42297218\nTitle: Current progress in the use of pyrazole-containing compounds for neuroprotection as a strategy to counteract neurodegeneration.\nAbstract: Pyrazoles, a versatile class of five-membered heterocyclic compounds, have attracted significant attention due to their broad biological activities, including neuroprotection. This review examines the role of pyrazole-containing compounds in protecting neuronal tissues against various forms of damage, such as oxidative stress, excitotoxicity, and neuroinflammation, which are critical contributors to neurodegenerative diseases, including Alzheimer's and Parkinson's diseases. The targets and molecular mechanisms through which pyrazoles exert their neuroprotective effects, including the modulation of signaling pathways, enzyme inhibition, and antioxidant activity, are also comprehensively discussed. Furthermore, recent advances in the design of pyrazole-bearing compounds with enhanced neuroprotective properties are highlighted through the presentation of key structure-activity relationships (SARs), emphasizing their therapeutic potential in the most prevalent neurodegenerative disorders, such as Alzheimer's disease (AD) and Parkinson's disease (PD). This review provides an up-to-date overview of pyrazoles, either as standalone scaffolds or in combination with other ring systems, in neuroprotection, thereby paving the way for future research and drug development in this promising field.\n\nID: 42280098\nTitle: Striatal Metabolomic Profiling Links Brazilian Green Propolis to Suberic Acid Modulation and Nigrostriatal Neuroprotection in a Rat Model of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is characterized by progressive nigrostriatal degeneration and striatal dysfunction, yet its metabolic remodeling remains incompletely defined. Here, untargeted GC-MS metabolomics was used to investigate the effects of standardized Brazilian green propolis on the striatal metabolic profile in the 6-hydroxydopamine (6-OHDA) rat model. Discriminant metabolites, including suberic acid, gluconic acid, heptadecane, and tartaric acid, distinguished experimental groups, capturing key features of the metabolic response to dopaminergic injury and treatment. Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways. Propolis treatment attenuated the elevation of suberic acid, accompanied by a reduction in gluconic acid levels, suggesting a metabolic profile linked to pathways involved in redox balance and glucose handling. Given previous reports identifying heptadecane as a hydrocarbon constituent of volatile propolis fractions, complementary GC-Q-TOF analyses demonstrated that heptadecane was absent from the administered extract, despite its consistent association with propolis-treated groups. Metabolic changes were accompanied by attenuation of nigrostriatal dopaminergic neurodegeneration and improved motor performance. Together, these findings delineate a striatal metabolic signature associated with Brazilian green propolis and identify suberic acid as a key metabolite linked to neuroprotection in experimental Parkinsonism.\n\nID: 42278259\nTitle: Jujube Polysaccharide Promotes Neuroprotection and Longevity in Caenorhabditis elegans Through Oxidative Stress Resistance and Stress-Response Signaling.\nAbstract: Parkinson's disease (PD) involves oxidative stress, proteotoxic aggregation, and neurotransmitter dysfunction, yet current therapies remain largely symptomatic. This study investigated whether Jujube polysaccharides (ZJP), a food-derived polysaccharide, confer neuroprotective and anti-aging benefits in Caenorhabditis elegans. ZJP was characterized for physicochemical features, antioxidant capacity, and in vivo safety. Effects were evaluated in wild-type N2 and PD models by measuring lifespan, locomotion, pharyngeal pumping, chemotaxis, \u03b1-syn::YFP fluorescence intensity, dopaminergic neuron integrity, adenosine triphosphate (ATP), reactive oxygen species (ROS), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and lipofuscin. Stress resilience was assessed under heat (37 \u00b0C) and H2O2 exposure. RT-qPCR profiled genes related to stress responses and neurotransmission. ZJP showed no detectable toxicity at tested doses. ZJP extended mean lifespan in N2 (10.3-14.1%) and NL5901 (9.1%), improved locomotion, pharyngeal pumping, and chemotaxis, reduced lipofuscin (26.8-50.6%), and increased survival under heat (23.6%) and oxidative stress (38.1%). In PD models, ZJP reduced \u03b1-syn::YFP fluorescence by up to 54.9%, protected dopaminergic neurons, and increased ATP. It also lowered ROS and MDA levels while raising SOD and CAT activities. Gene expression changes were associated with enhanced oxidative stress resistance and with altered expression of genes involved in SKN-1/DAF-16-related stress-response signaling. These findings provide preliminary evidence that ZJP may promote longevity, stress resilience, and neuroprotection in C. elegans models of PD, supporting its potential as a candidate for further investigation in neuroprotection.\n\nID: 42275700\nTitle: Allosteric activation of Trx1 by antagonizing nitrative modification at tyrosine 49 confers neuroprotection against ischemic stroke.\nAbstract: Ischemic stroke remains a leading cause of mortality and chronic disability worldwide, with limited therapeutic options. Tetramethylpyrazine (TMP) is a natural product with well-established clinical efficacy against ischemic stroke, yet its molecular target and mechanism of action remain elusive. By integrating a bifunctional photoaffinity TMP probe with stable isotope labeling by amino acids in cell culture and activity-based protein profiling (SILAC-ABPP), we identified thioredoxin 1 (Trx1) as a direct target of TMP. We demonstrate that TMP binds specifically to tyrosine 49 (Y49) on Trx1, antagonizes its nitrative modification, and functions as an allosteric activator. This binding enhances Trx1's reductase activity, strengthens its interaction with apoptosis signal-regulating kinase 1 (ASK1), and consequently suppresses the ASK1-p38/JNK signaling cascade. Genetic ablation of Trx1 or ASK1, or pharmacological induction of Trx1 nitration, completely abolishes TMP-mediated neuroprotection. Our findings not only decipher the mechanistic basis for TMP's clinical efficacy but also identify Y49 of Trx1 as a druggable allosteric site, unveiling a novel anti-nitrative therapeutic strategy for ischemic stroke and related disorders involving nitrative stress.\n\nID: 42274849\nTitle: \u03b1-Klotho as a central integrative signalling hub in cognitive function and neuroprotection in neurodegenerative diseases.\nAbstract: \u03b1-Klotho, a transmembrane protein predominantly expressed in the kidney and brain, has garnered significant attention for its anti-ageing and neuroprotective properties. Beyond its systemic role in mineral metabolism and oxidative stress regulation, emerging evidence highlights its critical involvement in maintaining cognitive function and protecting against neurodegenerative processes. This review explores the multifaceted role of \u03b1-Klotho in the central nervous system, emphasizing its physiological functions, underlying molecular mechanisms, and therapeutic potential. \u03b1-Klotho exerts neuroprotective effects by modulating calcium and phosphate homeostasis, attenuating oxidative stress, and suppressing neuroinflammation. Additionally, it regulates signalling pathways such as IGF-1, Wnt/\u03b2-catenin, and Nrf2, which are essential for neuronal survival and synaptic plasticity. Reduced \u03b1-Klotho expression has been linked to cognitive impairment, Alzheimer's disease, Parkinson's disease, and other age-related neurodegenerative disorders. Preclinical studies demonstrate that enhancing \u03b1-Klotho expression or administering a recombinant protein improves learning, memory, and neuronal resilience, positioning \u03b1-Klotho as a promising therapeutic target. However, challenges such as limited blood-brain barrier penetration, stability of recombinant forms, and incomplete mechanistic understanding hinder clinical translation. Overall, \u03b1-Klotho stands as a novel biomarker and a promising intervention strategy for mitigating neurodegeneration and promoting healthy brain ageing.\n\nID: 42260119\nTitle: A cross-species atlas of the dorsal vagal complex reveals neural mediators of the effects of cagrilintide on energy balance.\nAbstract: Amylin receptor agonists such as cagrilintide represent emerging obesity therapies. To understand mediators of cagrilintide action, we generated a transcriptomics atlas of over 530,000 cells comprising 80 neuronal cell populations across rat, mouse and macaque caudal brainstem, with spatial profiling to map distribution in the rat dorsal vagal complex (DVC). Here we show that cagrilintide regulates two conserved Calcr-expressing DVC neuronal populations. While acute cagrilintide treatment alters gene expression in area postrema Calcr/Ramp3 neurons, chemogenetic activation in rats fails to affect long-term food intake and body weight. In contrast, long-term cagrilintide treatment in rats upregulates prolactin-releasing hormone (Prlh) expression in nucleus of the solitary tract Calcr/Prlh cells that are conserved across rodents, macaques and humans. Knocking down DVC Prlh abrogates the effects of cagrilintide but not semaglutide in rats. Our study provides a cross-species spatially resolved atlas of DVC cell populations and defines Calcr/Prlh neurons as mediators of amylin receptor agonist action.\n\nID: 42260052\nTitle: Neurochemical Mechanisms Underlying Tanshinone-Mediated Neuroprotection and Formulation Strategies in Cerebral Ischemia/Reperfusion Injury.\nAbstract: Cerebral ischemia/reperfusion (I/R) injury represents a major pathological component of ischemic stroke and is driven by a complex cascade of neurochemical and molecular events, including excitotoxicity, oxidative and nitrosative stress, neuroinflammation, blood-brain barrier (BBB) disruption, mitochondrial dysfunction, and regulated cell death pathways such as apoptosis and ferroptosis. Tanshinones, a class of lipophilic diterpenoid quinones derived from Salvia miltiorrhiza (Danshen), have attracted increasing attention as multi-target neuroprotective agents in experimental models of cerebral I/R. Accumulating evidence demonstrates that major tanshinones, including tanshinone I, tanshinone IIA, tanshinone IIB, cryptotanshinone, and dihydrotanshinone I, modulate key neurochemical processes underlying cerebral I/R injury, including redox homeostasis, inflammatory signaling cascades, mitochondrial function, BBB integrity, and cell death regulatory networks. In parallel, recent advances in formulation strategies, including chemically modified derivatives (e.g., sodium tanshinone IIA sulfonate and the cryptotanshinone derivative DST-3), as well as microemulsions, liposomes, and nanoparticle-based delivery systems, have markedly improved aqueous solubility, pharmacokinetic behavior, and brain bioavailability of tanshinones, thereby potentially enhancing their neuroprotective effects in experimental models. This review comprehensively summarizes current evidence on the neurochemical and molecular mechanisms of tanshinones and their formulations in cerebral I/R injury, with an emphasis on signaling pathway modulation, redox regulation, mitochondrial protection, and formulation-driven improvements in brain delivery, and discusses remaining mechanistic challenges and future research directions.\n\nID: 42248290\nTitle: FTO knockdown confers neuroprotection in intracerebral hemorrhage rats by suppressing ferroptosis via inhibiting autophagy.\nAbstract: Intracerebral hemorrhage (ICH) has high disability rates and fatality. This study aims to investigate whether fat mass and obesity-associated protein (FTO) exacerbate ICH-induced brain injury by regulating autophagy-dependent ferroptosis and to identify potential therapeutic targets. An ICH model was established in rats via autologous blood injection. FTO expression was knocked down using adeno-associated virus-delivered short hairpin RNA (shRNA). Neurological scores, brain edema, and histopathology were assessed. Autophagy, oxidative stress, and ferroptosis markers were measured by Western blot and enzyme-linked immunosorbent assay (ELISA).Immunofluorescence was performed for FTO with neuronal nuclei (NeuN), glial fibrillary acidic protein (GFAP), ionized calcium-binding adapter molecule 1 (Iba-1), LC3, and GPX4/microtubule-associated protein 2 (MAP2). FTO expression was significantly upregulated post-ICH, correlating with neurological deterioration, cerebral edema, neuronal loss, and inflammatory infiltration. Immunofluorescence showed FTO colocalized with NeuN. FTO knockdown attenuated neurological deficits, reduced cerebral edema, and suppressed neuronal loss. FTO knockdown inhibited autophagy-related protein (ATG5)/microtubule-associated protein 1 light chain 3B (LC3B)-mediated autophagy activation, thereby mitigating iron overload, lipid peroxidation, and ferroptosis markers (decreased glutathione peroxidase 4 [GPX4], elevated acyl-CoA synthetase long-chain family member 4 [ACSL4], and cyclooxygenase-2 [COX2]). FTO knockdown also reduced LC3 fluorescence and restored GPX4/MAP2 colocalization. Rescue experiments further confirmed that ATG5 overexpression reversed the neuroprotective effects of FTO knockdown. FTO aggravates ICH-induced brain injury by promoting ATG5/LC3B-mediated autophagy and subsequent ferroptosis. Targeting FTO represents a promising therapeutic strategy to mitigate secondary brain damage post-ICH.\n\nID: 42223207\nTitle: Energy Stress-Induced Neuroprotection Against Ferroptosis in Dopaminergic Neurons.\nAbstract: Ferroptosis, an iron-dependent form of regulated necrosis, is implicated in the pathogenesis of Parkinson's disease (PD). We studied the influence of energy stress on ferroptosis in differentiated dopaminergic neurons (LUHMES). Glucose deprivation conferred protection against ferroptosis induced by erastin or arachidonic acid plus iron by reducing lipid peroxidation. Glucose withdrawal did not protect against RSL3-induced ferroptosis, suggesting that direct GPX4 inhibition cannot be reversed by metabolic modulation. The expression of ferroptosis markers ACSL4, GPX4, xCT, and TFRc remained unaltered during glucose deprivation. Inhibition of glycolysis using 2-deoxyglucose confirmed the role of energy stress in the regulation of ferroptosis. Activation of AMP-activated protein kinase (AMPK) by AICAR protected LUHMES cells from erastin-induced ferroptosis, even in the presence of glucose. Conversely, AMPK expression inhibition by siRNA re-sensitized cells to ferroptosis under glucose-free conditions. These findings suggest that glucose metabolism and AMPK-mediated energetic stress play crucial roles in regulating ferroptosis in dopaminergic neurons, with potential implications for understanding the mechanisms of neurodegeneration in PD. These findings identify a potential bioenergetic checkpoint regulating ferroptosis susceptibility under conditions of severe energy stress.\n\nID: 42214028\nTitle: Ergothioneine exerts neuroprotection in experimental ischemic stroke via activation of PI3K/Akt/Nrf2 pathway.\nAbstract: Ischemic stroke is a leading cause of serious long-term disability and mortality worldwide. Ergothioneine (EGT), a natural dietary sulfur-containing amino acid, possesses potent antioxidant properties. This study investigates the neuroprotective potential of EGT in experimental ischemic stroke and elucidates its underlying molecular signaling pathway. Two ischemic stroke models, the photochemical ischemia model and the middle cerebral artery occlusion (MCAO) model, were established to evaluate the neuroprotective effects of EGT. 2,3,5-Triphenyltetrazolium chloride staining was performed to assess infarct volume, and laser speckle contrast imaging was used to monitor cerebral blood flow. Immunofluorescence was employed to detect the activation of astrocytes and microglia. Proteins involved in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway were analyzed by Western blot to explore the underlying mechanism of EGT. In both photochemical ischemia and middle cerebral artery occlusion models, EGT significantly reduced infarct volume, improved cerebral perfusion and attenuated glial cells activation. Mechanistically, EGT promoted PI3K/Akt phosphorylation, reduced cytoplasmic Kelch-like erythroid cell-derived homology-associated protein 1 expression, and enhanced nuclear Nrf2 translocation. Notably, PI3K inhibitor, LY294002, completely abolished the neuroprotective effects of EGT. EGT exhibits significant neuroprotection against experimental ischemic stroke by mitigating oxidative stress and neuroinflammation, and its efficacy is critically dependent on the activation of the PI3K/Akt/Nrf2 signaling pathway.\n\nID: 42193898\nTitle: Uncovering the Secret of Mesenchymal Stromal Cells Secretome: From Extracellular Vesicle Cargo to Neuroprotection.\nAbstract: Mesenchymal stromal cells (MSCs), also known as multipotent stromal cells or mesenchymal stromal cells, support cell growth and viability through the secretion of trophic factors and immunomodulatory molecules. Their secretome exerts cytoprotective effects in the brain, although the mechanisms underlying MSC-mediated neurological recovery remain poorly understood. A substantial portion of the MSC secretome is delivered via extracellular vesicles (EVs), membrane-bound particles that facilitate intercellular communication. EVs derived from MSCs of various origins exhibit therapeutic potential, and numerous studies are examining the miRNA and protein cargo contained within MSC-EVs. Despite these efforts, methodological differences across the literature and the inherent variability associated with MSC sources have limited data interpretation and identification of EV-factors which may be responsible for neuroprotection. In this study, we have reviewed proteomic, transcriptomic and lipidomic datasets from a selection of recent MSC-EV studies, to identify shared cargo components that may contribute to promoting cell repair and plasticity in brain, counteracting neurodegeneration.\n\nID: 42189938\nTitle: Vagal activation inhibits insulin release through neuronal nitric oxide synthase in obese male mice.\nAbstract: The vagus nerve connects the brain and pancreas and enhances postprandial endocrine secretion from the pancreas through cholinergic signaling, such as increasing insulin release immediately after food intake in the cephalic-phase insulin response (CPIR). Here, we investigated how obesity affects vagal regulation of pancreatic endocrine function using designer receptors exclusively activated by designer drugs (DREADDs) to manipulate vagal activity. As expected, the plasma concentration of insulin was increased by vagal activation in mice expressing the excitatory DREADD hM3Dq (M3 mice) and decreased by vagal inactivation in mice expressing inhibitory DREADD hM4Di (M4 mice). However, vagal activation in M3 mice with diet-induced obesity did not elicit an early increase in insulin and instead produced a delayed insulin decrease. Mathematical modeling showed that plasma insulin dynamics in these mice were best explained by a model incorporating both the insulin-increasing and insulin-decreasing effects of the vagus nerve. Furthermore, the insulin-decreasing effect was mediated by nitric oxide (NO)-dependent, noncholinergic signaling and was enhanced in obesity. In obese M3 mice, vagal deficiency of neuronal NO synthase (nNOS) abolished the insulin-decreasing effect and restored insulin release after vagal activation. Vagal nNOS deficiency also enhanced insulin release after voluntary feeding, consistent with the CPIR. These findings suggest that vagal NO action inhibits postprandial insulin release, particularly in obesity.\n\nID: 42544450\nTitle: Gene dosage imbalance disrupts systemic metabolism in the Dp16 Down syndrome mouse model.\nAbstract: Gene dosage imbalance resulting from an extra copy of human chromosome 21 (Hsa21) contributes to numerous clinical features in Down syndrome (DS). While dysregulated metabolism has long been noted in DS, the underlying cause is poorly understood and vastly understudied. To fill this critical knowledge gap, we conducted a comprehensive metabolic analysis of Dp(16)1Yey/+mice (abbreviated Dp16), a segmental duplication model carrying ~58% of the triplicated Hsa21 gene orthologs. Our multi-tissue transcriptomic analyses reveal shared and sex-specific increases in expression dosage of the triplicated genes in white and brown adipose tissues, liver, skeletal muscle, and hypothalamus. Despite sexual dimorphism in body weight, body temperature, food intake, and physical activity, Dp16 males and females share striking core phenotypes of pronounced insulin resistance, glucose intolerance, impaired lipid clearance, and dyslipidemia. Functional assessments, combined with biochemical, transcriptomic, and metabolomic analyses reveal tissue signatures of immune activation and a pro-inflammatory state, ER and oxidative stress, fibrosis, impaired glucose and fatty acid catabolism, altered lipid and bile acid profiles, and reduced mitochondrial respiratory capacity in Dp16 mice. These concerted changes disrupt homeostatic mechanisms that underpin metabolic health, contributing to systemic metabolic dysfunction. An obesogenic diet further exacerbates insulin resistance in Dp16 males and females despite divergent weight gain. The collective phenotypes broadly reflect the metabolic profile of DS. Our extensive molecular, biochemical, and physiological data provide an essential foundation for genetic dissection of dosage-sensitive genes affecting glucose and lipid metabolism, and for testing therapeutic strategies to improve metabolic outcomes in DS.\n\nID: 42544301\nTitle: Neuroprotective Delivery of Dexmedetomidine Liposomes Mitigates Cerebral Energy Crisis by Modulating Calcium-Driven Aerobic Glycolysis in Cerebral Ischemia-Reperfusion Injury.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) involves complex pathogenesis with limited therapeutic options. This study investigated whether dexmedetomidine liposomes (Dex-lip) exert neuroprotective effects by modulating astrocytic aerobic glycolysis via calcium signaling. In vivo CIRI model mice received Dex-lip, with or without the aerobic glycolysis inhibitor 2-deoxy-D-glucose (2-DG). Neurological function, cortical calcium levels, aerobic glycolysis-related protein expression, lactate production, and hippocampal neuronal damage were assessed. In vitro, astrocytes were treated with the calcium channel blocker nifedipine to evaluate intracellular calcium, lactate levels, and glycolysis-related gene expression. Dex-lip treatment reduced cortical calcium overload, upregulated aerobic glycolysis key proteins, increased lactate production, and attenuated hippocampal neuronal injury. These neuroprotective effects were abolished by 2-DG. In vitro, nifedipine lowered astrocytic calcium concentration, which paradoxically increased lactate production, elevated ECAR, and upregulated HK1, HK2, and PFK1 mRNA expression, confirming that calcium reduction promotes aerobic glycolysis. Dex-lip ameliorates CIRI by reducing astrocytic calcium overload, enhancing aerobic glycolysis and lactate supply to neurons, thereby preventing apoptosis. This study provides a mechanistic basis and therapeutic strategy for CIRI.\n\nID: 42544276\nTitle: Magnolia biondii-Derived Exosome-Like Nanoparticles Ameliorate Ulcerative Colitis by Suppressing Inflammation, Reducing Oxidative Stress, and Modulating Gut Microbiota.\nAbstract: Ulcerative colitis (UC) is a chronic, relapsing inflammatory bowel disease with limited treatment options and suboptimal remission rates. Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals.\n\nID: 42543384\nTitle: Two stress-responsive kinases suppress ferroptosis by activating antioxidant programs under mild oxidative stress.\nAbstract: Cancer cells maintain chronically elevated levels of reactive oxygen species (ROS) while relying on robust antioxidant programs to preserve redox homeostasis and viability. Although therapeutic strategies that disrupt this balance to induce lethal oxidative stress and ferroptosis have emerged as promising anticancer approaches, the upstream signaling mechanisms that constrain ROS accumulation under physiologically relevant stress conditions remain incompletely understood. Here, we identify the stress-responsive kinases SMG1 and DNA-dependent protein kinase (DNA-PK) as functionally redundant regulators of redox homeostasis and ferroptosis resistance. Genetic or pharmacological inhibition of either kinase triggers ferroptotic cell death, accompanied by marked accumulation of total ROS, ferrous iron, and lipid hydroperoxides. Mechanistically, under mild oxidative stress, SMG1 and DNA-PK cooperatively phosphorylate the central antioxidant transcription factor NRF2 at serine 13 and serine 40, weakening its interaction with the negative regulator KEAP1 and promoting NRF2 accumulation and transcriptional activation. Transcriptomic profiling of de novo mRNAs revealed that inhibition of either kinase is sufficient to suppress NRF2-driven antioxidant gene expression. In contrast, excessive oxidative stress overrides this pro-survival pathway and redirects signaling toward anti-survival responses mediated by ATF4, ATM-CHK2, and JNK/p38 pathways. Collectively, these findings uncover a previously unrecognized SMG1/DNA-PK-NRF2 signaling axis that functions as a redox stress-intensity-dependent switch governing cell fate decisions between antioxidant adaptation and ferroptotic death. Targeting this axis may represent a promising therapeutic strategy for cancer treatment.\n\nID: 42543327\nTitle: [Research progress on mechanisms and therapeutic potential of active components of TCM in intervening lipid metabolism reprogramming in colorectal cancer].\nAbstract: Lipid metabolism reprogramming is a hallmark metabolic feature in the pathogenesis and progression of colorectal cancer(CRC), primarily involved in the aberrant activation of de novo lipogenesis(DNL), disruption of cholesterol homeostasis, enhancement of fatty acid oxidation(FAO), and resistance to ferroptosis. All of these pathological processes mediate malignant progression and multidrug resistance of tumors. According to TCM, the pathological foundation of CRC lies in the interlocking of "dampness, heat, stasis, and deficiency", which exhibits an intrinsic biological consistency with ectopic lipid accumulation, metabolic pathway perturbations, and the imbalance of microenvironmental homeostasis. This article systematically reviewed the molecular regulatory networks of lipid metabolism reprogramming in CRC, emphasizing the molecular mechanisms by which active components of TCM intervene in lipid metabolism homeostasis by modulating core targets such as sterol regulatory element-binding proteins(SREBPs), glutathione peroxidase 4(GPX4), solute carrier family 7 member 11(SLC7A11), and carnitine palmitoyltransferase 1(CPT1). Pharmacological studies demonstrate that active ingredients, including berberine, tanshinone \u2161_A, ginsenosides, curcumin, and hesperetin, elucidate the molecular scientific connotations of therapeutic principles, such as "clearing heat, drying dampness, promoting blood circulation, removing toxic substances, strengthening body resistance to consolidate the constitution, and disinhibiting dampness to transform phlegm", by intervening in lipid synthesis, ferroptosis, energy metabolism, and inflammatory signaling pathways. Furthermore, the clinical application potential of active components of TCM in reversing chemotherapy resistance, synergizing with immunotherapy, and the chemoprevention of adenomas is systematically evaluated. By providing an in-depth analysis of the biological correlations between TCM syndrome theory and lipid metabolism regulation, this review aims to offer a pharmacological basis for the development of TCM candidates targeting metabolic remodeling and for the optimization of diagnostic and therapeutic protocols of integrated Chinese and western medicine.\n\nID: 42543326\nTitle: [Research progress on action mechanisms of Rheum palmatum anthraquinones in improving acute lung injury].\nAbstract: Acute lung injury(ALI) and acute respiratory distress syndrome(ARDS) are severe respiratory diseases characterized by uncontrolled inflammatory responses and disruption of the alveolar-capillary barrier. This type of disease is often triggered by multiple factors such as infection, sepsis, trauma, or inhalation injury, and the pathological process involves multiple sections including inflammatory cascade reactions, oxidative stress imbalance, abnormal activation of immune cells, and increased pulmonary microvascular permeability. Owing to their complex pathogenesis and high mortality, available clinical therapeutic approaches remain limited. Therefore, the development of safe and effective therapeutic agents to attenuate ALI has become a major focus of current research field. As a TCM, Rheum palmatum has a long history of use in clearing heat and toxins, purging the bowels, and regulating systemic inflammatory responses. In recent years, increasing attention has been paid to its therapeutic effect in ALI. RESULTS:: show that R. palmatum and its major bioactive anthraquinones, such as emodin and rhein, exert protective effects through multi-target and multi-pathway mechanisms. These mechanisms mainly include inhibition of inflammatory signaling pathways such as nuclear factor-\u03baB(NF-\u03baB), mitogen-activated protein kinase(MAPK), and NOD-like receptor protein 3(NLRP3) inflammasome, attenuation of oxidative stress response, activation of the nuclear factor erythroid 2-related factor 2(Nrf2)-mediated antioxidant defense system, regulation of programmed death in immune cells including macrophages, improvement of immunometabolic status, modulation of macrophage polarization and the gut microbiota as well as the gut-lung axis, and so on. In addition, R. palmatum has been shown to preserve the integrity of the alveolar-capillary barrier and to suppress excessive neutrophil activation and the overformation of neutrophil extracellular traps(NETs), thereby reducing inflammation amplification effect and the risk of immune microthrombi. This paper summarized the action mechanisms and research progress of R. palmatum in the treatment of ALI, aiming to elucidate the unique advantages of R. palmatum anthraquinones in intervening in the complex pathological processes of ALI through systemic regulatory networks and to provide a solid theoretical basis for the research and development of innovative R. palmatum-based medicines and their clinical combination medication.\n\nID: 42543314\nTitle: [Mechanistic study of Scutellariae Radix against atherosclerosis through inhibition of pyroptosis based on network pharmacology and experimental verification].\nAbstract: This study systematically investigated the mechanism of Scutellariae Radix against atherosclerosis(AS) through the integrated application of network pharmacology, molecular docking, and animal experiments. A total of 34 active ingredients of Scutellariae Radix were screened from the TCMSP database, and 65 potential therapeutic targets were identified by combining SwissTargetPrediction and GEO data analysis. Protein-protein interaction(PPI) network construction, molecular docking, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses indicated that Scutellariae Radix might exert the anti-AS effect by modulating inflammatory responses, negatively regulating pyroptosis, and influencing the NOD-like receptor(NLRP) signaling pathway. In vivo, AS was induced in ApoE~(-/-) mice by 16-week high-fat diet feeding, followed by intervention with Scutellariae Radix extract. The results showed that Scutellariae Radix significantly attenuated lipid deposition and plaque area in the aortic wall, decreased serum levels of total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG), and increased the high-density lipoprotein cholesterol(HDL-C) level, thereby improving lipid metabolism disorders. Meanwhile, it markedly inhibited the expression of proinflammatory cytokines tumor necrosis factor-\u03b1(TNF-\u03b1), interleukin(IL)-1\u03b2, and IL-6. In addition, Scutellariae Radix significantly suppressed nuclear factor-\u03baB(NF-\u03baB) phosphorylation and downregulated the protein expression of NOD-like receptor pyrin domain-containing protein 3(NLRP3), cleaved caspase-1, and the N-terminal fragment of gasdermin D(N-GSDMD), which suggested that Scutellariae Radix effectively inhibited pyroptosis in arterial tissues. Collectively, these findings suggested that Scutellariae Radix ameliorated AS by suppressing pyroptosis in arterial tissues, attenuating inflammation, and improving lipid metabolism via regulating the NLRP3/caspase-1/GSDMD signaling pathway.\n\nID: 42543301\nTitle: [Comparative research on efficacy of high-pressure Schisandrae Chinensis Fructus decoction pieces and traditional decoction pieces on nonalcoholic fatty liver disease mice based on gut microbiota and metabolomics].\nAbstract: This paper aims to evaluate the feasibility of clinical application of high-pressure Schisandrae Chinensis Fructus decoction pieces(HPSCH) compared with that of traditional Schisandrae Chinensis Fructus decoction pieces(SCH), based on the efficacy of mice with nonalcoholic fatty liver disease(NAFLD) induced by a high-fat diet. The optimal preparation process of HPSCH was investigated by using schisandrin content and total extractive yield as indices. After one week of adaptive feeding, C57BL/6 mice were assigned to a normal control group, while the remaining mice were fed an HFD for eight weeks to establish the NAFLD mouse model. After being successfully modeled, the mice were divided into a blank control group, blank administration group, simple model group, fenofibrate group, SCH group, and HPSCH group. All groups were administered by intragastric administration for four weeks. Body weight changes of mice were recorded, and liver indices were calculated. The levels of blood lipid and liver function index in the serum of mice were measured. Hepatic histopathological changes were observed by using hematoxylin-eosin(HE) staining and oil red O staining. Mice's feces were collected, and the 16S rDNA high-throughput sequencing method was employed to analyze changes in the gut microbiota of mice. Untargeted lipidomic analysis of the liver was conducted by using liquid chromatography-mass spectrometry(LC-MS), and principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were adopted to screen and identify differential metabolites. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to perform relevant pathway analysis. Integrated analyses of gut microbiota and differential metabolites were performed to compare the similarities and differences in efficacy of HPSCH and SCH. The results show that both the HPSCH group and SCH group exert similar effects on biochemical indices in serum and hepatic pathological changes, lipid metabolism can be regulated, and liver injury in NAFLD mice can be improved. The two groups show similar changes in microbial abundance, trending toward the blank control group and maintaining intestinal homeostasis. Compared with those of the simple model group, the differential metabolites and metabolic pathways of both the HPSCH group and SCH group show similarity, and the differential metabolites are mainly triglycerides, diglycerides, phosphatidylcholines, phosphatidylglycerols, and so on. Metabolic pathways include glycerophospholipid metabolism, choline metabolism, retrograde endocannabinoid signaling, thermogenic lipolysis, and so on. This indicates that HPSCH and SCH share common advantages in improving hepatic function in mice and achieve comparable effects. HPSCH can improve blood lipid and liver function indices in NAFLD mice, attaining the therapeutic effect through the regulation of gut microbiota and lipid metabolism. Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application. Moreover, the application of HPSCH may contribute to the conservation of medicinal resources.\n\nID: 42543294\nTitle: [Overall pathophysiological network of sarcopenia secondary to chronic heart failure from perspectives of modern medicine and TCM].\nAbstract: Sarcopenia is a common and serious complication of chronic heart failure(CHF), with the two conditions forming a vicious cycle. However, the systemic pathological network underlying sarcopenia secondary to CHF remains unclear. This review constructed a multi-level mechanistic framework. Starting from the macroscopic hemodynamic disorders and neuroendocrine activation caused by CHF, the review proceeded to explain how they lead to mesoscopic multi-organ crosstalk dysfunction(including intestinal barrier damage/elevated trimethylamine N-oxide, impaired hepatic synthesis, pulmonary edema, and renal water-sodium retention). These alterations collectively created a systemic milieu characterized by chronic inflammation, oxidative stress, and insulin resistance. This milieu, in turn, triggered a series of microscopic lesions in skeletal muscle, encompassing metabolic imbalance of protein, neuromuscular junction degeneration, microcirculatory disturbances, and myokine secretion dysregulation, all of which ultimately converged, via mitochondrial dysfunction, on a common terminal pathway called "energy metabolism collapse." This review further interpreted this process through the lens of TCM theory, attributing it to a systemic dysfunction rooted in the progression from "Qi deficiency in heart" to "Yang deficiency in heart". This deficiency led to "Yang Qi counterflow" and "three energizer blockage", and the ensuing "internal toxin" and "sthenic fire", corresponding to the states of chronic inflammation and oxidative stress in modern medicine. The multi-level mechanistic framework proposed herein not only elucidates the active role of skeletal muscle via the "muscle-heart axis" but also thereby lays a theoretical foundation for future therapeutic strategies based on multi-target regulation and the integration of TCM and western medicine.\n\nID: 42543261\nTitle: BCL9 inhibition promotes fibroblast lipogenesis by regulating macrophage-fibroblast interactions to attenuate pulmonary fibrosis.\nAbstract: Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease with an urgent need for novel therapeutic strategies. M2 macrophage-derived TGF-\u03b21 promotes fibroblast myogenesis, contributing to IPF pathogenesis. Targeting macrophage polarization and fibroblast function thus represents an effective therapeutic approach for treating IPF. Here, we identify B-cell lymphoma 9 (BCL9) as a key upstream regulator implicated in IPF pathogenesis. We demonstrate that BCL9 drives the macrophage M2 program through the MerTK-ERK-SPP1 axis. Notably, pharmacological inhibition of BCL9 with our novel peptide, hsBCL9Z96, effectively attenuates pulmonary fibrosis by reprogramming macrophage-fibroblast crosstalk. Specifically, BCL9 inhibition promotes fibroblast lipogenesis via TGF-\u03b21 signaling, which in turn supports alveolar type 2 (AT2) cell expansion. This macrophage-orchestrated fibroblast phenotypic switch from myogenic to lipogenic is visually corroborated by spatial transcriptomic analyses and immunofluorescence staining of human lung tissues. Functionally, the pathological role of BCL9 and efficacy of hsBCL9Z96 are validated in human cellular models, including IPF patient-derived cells, confirming its translational significance. Collectively, our findings not only elucidate a novel BCL9-driven macrophage-fibroblast-AT2 cell axis in IPF but also establish hsBCL9Z96 as a promising first-in-class therapeutic candidate, providing a strong rationale for targeting BCL9-mediated Wnt signaling in clinical IPF treatment.\n\nID: 42543026\nTitle: Functional Role of ALKBH5 in Kidney Injury: Insights Into Mechanisms and Therapeutic Potential.\nAbstract: ALKBH5, as an m6A demethylase, plays a crucial regulatory role in various kidney diseases such as acute kidney injury, chronic kidney disease, renal fibrosis and renal cell carcinoma. However, its function often exhibits contradictory effects: In renal fibrosis, ALKBH5 has been reported to both promote and suppress fibrogenesis, whereas in renal cell carcinoma most studies support an oncogenic role, but some clinical observations link ALKBH5 downregulation to poor prognosis. These contradictions may stem from differences in cell types, disease stages, and microenvironments. This manuscript systematically reviews the complex function of ALKBH5 in kidney diseases and its underlying mechanisms, explores its potential as a therapeutic target, evaluates its therapeutic potential, and highlights the need for cell- and pathology-specific strategies to enable precise intervention. Future research should focus on its cell and pathological background specificity to achieve precise intervention.\n\nID: 42543015\nTitle: [Albuminuria for detection of chronic kidney disease: biomarker and therapeutic target].\nAbstract: Albuminuria is one of the most important biomarkers of chronic kidney disease and also a target that can be influenced by treatment. The amount of albumin excreted in the urine is an independent predictor of declining kidney function, cardiovascular events, and all-cause mortality. It is most easily determined based on the albumin-to-creatinine ratio (ACR) measured in the first morning urine sample; in the vast majority of cases, 24-hour urine collection is not required. The pathophysiology of albuminuria centers on damage to the glomerular filtration barrier - particularly podocytes - hemodynamic hyperfiltration, inflammation associated with tubular protein reabsorption, and activation of the renin-angiotensin-aldosterone system (RAAS). Modern four-pillar pharmacotherapy - RAS inhibitors (ACE inhibitors/ARBs), SGLT2 inhibitors, non-steroidal mineralocorticoid receptor antagonists (finerenone), and GLP1 receptor agonists in type 2 diabetes - acts on these processes through complementary mechanisms. When tailored to the degree of albuminuria and eGFR, this treatment significantly slows the progression of chronic kidney disease and reduces cardiovascular risk. Measuring and monitoring albuminuria must therefore be an essential part of daily clinical practice. Orv Hetil. 2026; 167(31): 1231-1237.

Increasing evidence supports the view of HFpEF as a systemic inflammatory syndrome driven by aging and cardiometabolic comorbidities, including obesity, hypertension, and chronic kidney disease. Within this framework, regulatory T cells (Tregs), which are essential for maintaining immune tolerance and limiting excessive inflammation, have emerged as important modulators of disease progression. However, the mechanisms underlying Treg dysfunction in HFpEF have remained poorly understood. In this issue, Srinivas et al. identify stromal interaction molecule 1 (STIM1)-dependent calcium signaling as a critical regulator of Treg instability in HFpEF. The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways. Using a cardiometabolic murine model and Treg-specific STIM1 knockout mice, they establish a causal role for Treg-intrinsic STIM1 signaling in disease development. These findings position STIM1 as a molecular link between cardiometabolic stress, immune dysregulation, and cardiac remodeling. They further support the concept that immune-cell plasticity is a major determinant of HFpEF pathogenesis and suggest that preserving Treg stability may represent a novel therapeutic strategy. Although important questions remain regarding disease timing, clinical translation, and sex-specific effects, this work advances our understanding of HFpEF as an immune-mediated disorder and identifies STIM1-dependent calcium signaling as a promising therapeutic target.\n\nID: 42542536\nTitle: Mass Spectrometry Analysis of Biotherapeutic Monoclonal Antibody Glycosylation.\nAbstract: Glycosylation plays a critical role in the efficacy of therapeutic monoclonal antibodies (mAbs), the major category of glycoprotein-based therapeutic medicines. It is claimed that glycosylation of therapeutic mAbs has implications on their half-life, immunogenicity, and pharmacokinetics. Comprehensive characterization of glycosylation enables a deeper understanding of the complexity of therapeutic mAbs. The method presented here describes an integrated approach that incorporates filtered-aided sample preparation, mass spectrometry with different ion activation techniques, and a software that enables intact glycopeptide database search and de novo sequencing, to provide both N- and O-linked glycan profiling with structural resolution, without performing pre-glycoprotein/glycopeptide enrichment.\n\nID: 42542520\nTitle: Post-Translational Modifications in Protein Therapeutics: Importance and Analytical Tools.\nAbstract: Post-translational modifications (PTMs) play a pivotal role in the activity and stability of proteins and can, therefore, significantly affect the quality of protein- or cell-based biological therapeutic products. Accordingly, PTMs are often evaluated as critical quality attributes, which require thorough characterization and evaluation throughout product development. Continued progress in understanding and characterizing protein PTMs is important to enable the distribution of safe and effective biologic medicines. Currently, a wide range of analytical techniques are employed for the detection and characterization of PTMs in the biopharmaceutical context. This chapter provides an overview of PTMs relevant to therapeutic proteins and commonly used or emerging analytical tools to analyze them.\n\nID: 42541673\nTitle: Ellagic acid and gallic acid combination attenuates pulmonary fibrotic responses in vitro: evidence suggesting involvement of the 5-HT2B/Ca\u00b2\u207a/inflammatory axis.\nAbstract: Pulmonary fibrosis (PF) is a progressive interstitial lung disease driven by aberrant extracellular matrix (ECM) remodeling and alveolar destruction. While serotonin (5-HT) promotes fibrogenesis via the 5-HT2B receptor, pharmacological interventions targeting this specific pathway remain scarce. Using a spectrum-effect approach, we screened bioactive phenolic acids from Rosa roxburghii Tratt extracts in a TGF-\u03b21-induced A549 cell model. Evaluating ellagic acid (EA), syringic acid (SA), and gallic acid (GA) both individually and in combination revealed that the EA/GA pairing (EG) yielded the most robust anti-fibrotic activity. Specifically, EG restored E-cadherin expression while suppressing key mesenchymal markers, effectively blunting epithelial-mesenchymal transition (EMT) in vitro. At the signaling level, EG treatment correlated with a downregulation of 5-HT2B-associated pathways, alongside marked reductions in oxidative stress and calcium influx. Our data suggest that EG dampens the Gq-PLC\u03b2-IP3R module, limiting both intracellular calcium mobilization and subsequent NFATc1 activation. Concurrently, we observed a suppression of the CaMKII-dependent NF-\u03baB cascade and its downstream pro-inflammatory targets (TNF-\u03b1, IL-6, and COX-2). These findings indicate that the EG combination alleviates pro-fibrotic responses in A549 cells by disrupting the 5-HT2B/calcium/inflammation axis. Although in vivo validation is required, this plant-derived combination offers a promising multi-targeted therapeutic strategy against pulmonary fibrosis.\n\nID: 42541598\nTitle: Mutant p53-R280K hijacks SREBP1 to promote fatty acid synthesis and breast cancer progression via FASN.\nAbstract: Lipid metabolic reprogramming is a hallmark of cancer, in which fatty acid synthesis is crucial for the rapid proliferation and metastasis of cancer cells. The p53-R280K mutation drives aggressive cancer, yet its role in fatty acid synthesis remains unclear. The CRISPR/CasRx technique was applied to knockdown endogenous mutant p53-R280K in MDA-MB-231 cells and wild-type p53 (WT-p53) in ZR75-1 cells. Luciferase reporter and ChIP assays demonstrated mutant p53-R280K binding to the FASN promoter and regulating its activity. Oil red O staining, flow cytometry, and triglyceride assays were used to determine the levels of lipid synthesis. Cell proliferation, wound healing and cell invasion assays were performed to detect the malignant phenotypes in vitro. Subcutaneous tumorigenesis and lung metastasis models of nude mice were established to validate tumor growth and metastasis in vivo. In this study, we reveal that p53-R280K hijacks the lipogenic transcription factor SREBP1 to form a transcriptional co-activation complex. This complex binds to and activates the fatty acid synthase (FASN) promoter, upregulating FASN expression. Enhanced FASN activity fuels de novo fatty acid synthesis, increasing lipid accumulation in breast cancer cells. Crucially, p53-R280K promotes cell proliferation, migration, and invasion in vitro, and drives tumor growth and lung metastasis in vivo in a FASN-dependent manner, as genetic or pharmacological inhibition of FASN abolishes these oncogenic effects. These findings establish that p53-R280K acquires a gain-of-function by co-opting SREBP1 to activate FASN transcription, reprogramming lipid metabolism to fuel breast cancer progression. Targeting the p53-R280K/SREBP1/FASN axis presents a promising therapeutic strategy for cancers harboring this specific p53 mutation.\n\nID: 42541586\nTitle: Research progress of traditional Chinese medicine interventions for aging-related nervous system diseases.\nAbstract: Aging-related neurological disorders, including stroke, Alzheimer's disease (AD), Parkinson's disease (PD), epilepsy, and various neuroinflammatory conditions, affect over three billion individuals worldwide and constitute leading causes of morbidity, disability, and socioeconomic burdens. Aging contributes not only to the increased incidence of these disorders but also to their progression through interconnected mechanisms, including endothelial dysfunction, oxidative stress, chronic inflammation, mitochondrial dysfunction, cellular senescence, metabolic imbalance, and gut microbiota dysbiosis. These processes collectively impair neuronal survival, synaptic plasticity, and cognitive and motor functions. Traditional Chinese medicine (TCM), with its characteristic multi-component and multi-target therapeutic strategies, has emerged as a promising approach to counteract age-associated neurological decline. Accumulating preclinical studies suggest that TCM interventions may exert neuroprotective, anti-inflammatory, and antioxidant effects, modulate autophagy, restore metabolic homeostasis, and potentially delay cellular senescence. However,\u00a0high-quality clinical evidence on safety and efficacy remains limited. This review summarizes current insights into the molecular interplay between aging and neurological disorders and highlights the therapeutic potential of TCM in targeting hallmarks of aging, providing perspectives for integrative prevention and treatment strategies for neurodegenerative and neurovascular diseases.\n\nID: 42541525\nTitle: Critical role of endothelial regulator of G protein signaling 5 in postnatal angiogenesis.\nAbstract: Regulator of G protein signaling 5 (RGS5) modulates G-protein coupled receptor (GPCR) signaling and is markedly upregulated in angiogenesis. However, its function in endothelial cells and its role in mediating postnatal angiogenesis remain unclear. The purpose of this study is to define the role of endothelial RGS5 in regulating VEGF signaling and angiogenesis. In a hindlimb ischemia model, we found impaired postnatal angiogenesis, reduced perfusion recovery, and increased rates of auto-amputation in mice with either global or endothelial-specific deletion of Rgs5. Rgs5 deficiency in ECs led to reduced VEGFR2 phosphorylation at Tyr1175 and its downstream signaling pathways. This was accompanied by increased activity of the tyrosine phosphatase, SHP-1, which dephosphorylates and inactivates VEGFR2. In vitro, Rgs5-deficient ECs exhibited diminished migration, increased apoptosis, and reduced viability in response to VEGF stimulation. These findings indicate that RGS5 is essential for maintaining VEGF-mediated angiogenic signaling through inhibition of SHP-1 activity. Endothelial RGS5 is a critical regulator of VEGF signaling and postnatal angiogenesis. By attenuating SHP-1-mediated dephosphorylation of VEGFR2, RGS5 preserves VEGF signaling and angiogenesis. Targeting the RGS5-SHP-1 axis may be a useful therapeutic strategy for improving angiogenesis in response to ischemia.\n\nID: 42541343\nTitle: Lactylation Signatures as Predictors of Prognosis and Therapeutic Response in Lung Adenocarcinoma: Implications for Ultrasound-Based Therapeutic Strategies.\nAbstract: Lactylation, a unique post-translational alteration, has been identified as an important epigenetic regulator of cancer metabolism, immune evasion, and treatment resistance. Recent research reveals that ultrasound-based biophysical stimulation may change tumor microenvironmental variables that affect lactate metabolism and subsequent lactylation processes. The purpose of this study was to better understand the predictive significance of lactylation-associated genes in lung adenocarcinoma (LUAD) and how they could interact with ultrasound-mediated treatment response. Transcriptomic data from 867 LUAD samples were used to identify lactylation-related genes. Consensus clustering was used to separate LUAD cases into various lactylation subtypes. Differentially expressed genes were assessed for functional enrichment, mutation load, and immunological infiltration. A prognostic risk model was created using multivariate Cox regression analysis. Nineteen major lactylation-related genes divided patients with LUAD into three molecular subgroups with different clinical outcomes. A 10-gene prognostic model accurately predicted overall survival and was associated with stronger tumor stemness, increased mutational frequency, and decreased immunotherapy effectiveness in high-risk patients. Notably, computational predictions suggested that metabolic regulation might slow lactylation-driven tumor development, implying a synergistic treatment window. Lactylation-associated gene profiles may serve as prognostic biomarkers and therapeutic modulators in LUAD. The combination of ultrasound-based therapies targeting lactylation pathways could be a viable technique for improving precision oncology and overcoming resistance mechanisms in lung cancer therapy.\n\nID: 42189322\nTitle: FOXO transcription factors in Alzheimer's Disease: balancing neuroprotection and neuronal degeneration.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative condition marked by the accumulation of amyloid-\u03b2, hyperphosphorylation of tau, oxidative stress, synaptic dysfunction, and neuroinflammation. Recent research underscores the Forkhead box O (FOXO) family of transcription factors (FOXO1, FOXO3, FOXO4, FOXO6) as crucial regulators of these pathogenic processes. FOXOs regulate antioxidant defenses, autophagy, mitochondrial quality control, and apoptosis by functioning downstream of insulin/PI3K-Akt and stress-responsive pathways. This context-dependent activity enables FOXOs to act as dual regulators: brief activation improves proteostasis, oxidative stress tolerance, and synaptic resilience, whereas dysregulated signaling triggers pro-apoptotic and neurodegenerative pathways. Genetic and pharmacological studies targeting FOXO signaling highlight its potential as a therapeutic target; nonetheless, obstacles persist, including isoform specificity, compensatory feedback mechanisms, and transport across the blood-brain barrier. This review consolidates contemporary understanding of the structural and functional functions of FOXO isoforms in AD, their participation in amyloid and tau pathology, oxidative stress, and neuroinflammation, and assesses options for therapeutic control. A deeper understanding of FOXO signaling could lead to novel therapies that utilize its neuroprotective properties specifically, while minimizing adverse effects.\n\nID: 42184753\nTitle: Physical activity and the brain barriers: Mechanisms of neuroprotection and disease resilience.\nAbstract: The central nervous system (CNS) is protected by specialized barriers, including the blood-brain barrier (BBB), the blood-cerebrospinal fluid barrier, and the meningeal barriers, which collectively regulate molecular exchange and maintain neural homeostasis. Increasing evidence demonstrates that these barriers are not static structures but dynamically respond to systemic physiological stimuli like physical activity (PA), a voluntary behavior that elicits systemic physiological adaptations. This review summarizes current knowledge on the structural and functional organization of the CNS barriers, key biomarkers of their integrity, and the mechanisms through which PA modulates barrier function and properties. Available data consistently indicate that regular PA enhances BBB stability by upregulating tight junction proteins, reducing oxidative stress, suppressing pro-inflammatory signaling, improving endothelial function, and modulating the kynurenine pathway. PA-induced adaptations also appear to strengthen barrier resilience under both physiological conditions and in pathological states, such as ischemic stroke, traumatic brain injury, neurodegenerative diseases, and stress-related psychiatric disorders. Collectively, the evidence supports the concept that PA can act as a non-pharmacological strategy promoting CNS barrier integrity and neurovascular health. However, further mechanistic and longitudinal studies are required to clarify dose-response relationships, PA modality-specific effects, and translational implications for clinical populations, while also integrating the coordinated roles of multiple CNS barriers and addressing potential sex-specific differences in these responses.\n\nID: 42183902\nTitle: PRDX2 Mediates the Neuroprotective Role of Umbilical Cord Blood Exosomes via the CYP2J2/8,9-EET Pathway in Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a severe neurodegenerative disorder marked by progressive dopaminergic loss, oxidative stress, metabolic dysregulation, and neuroinflammation. Umbilical cord blood-derived exosomes (UCB-Exos) have emerged as a promising cell-free therapeutic strategy, yet the precise molecular mechanisms underlying their neuroprotective properties remain largely unknown. This study highlights Peroxiredoxin-2 (PRDX2) as an important antioxidant protein within UCB-Exos that mediates their neuroprotective effects in PD models. Using advanced multi-omics approaches, including proteomics, metabolomics, and transcriptomics, we demonstrate that PRDX2 is selectively enriched in UCB-Exos compared to peripheral blood-derived exosomes. UCB-Exos, through the delivery of PRDX2, partially restore antioxidant defenses in neurons, attenuate neuroinflammation, and promote cellular survival. Moreover, UCB-Exos were found to modulate arachidonic acid metabolism by upregulating the levels of 8,9-epoxyeicosatrienoic acid (8,9-EET), a key metabolite with anti-inflammatory properties. Mechanistically, PRDX2 appears to protect the enzyme CYP2J2 from oxidative degradation, facilitating the production of 8,9-EET and reducing the NF-\u03baB/COX-2-driven inflammatory response, thus potentially mitigating neurodegeneration. This study provides evidence for a potential pathway, the PRDX2-mediated metabolic regulatory pathway, and highlights the therapeutic potential of UCB-Exos, offering a novel strategy in the development of exosome-based treatments targeting oxidative stress and neuroinflammation in neurodegenerative diseases.\n\nID: 41941960\nTitle: Greek Yogurt Compared with Whey Protein Supplementation in Adolescent Athletes Throughout a Competitive Season.\nAbstract: Protein intake during adolescence may influence bone development and immune status, yet the comparative effects of wholefood protein sources compared with protein isolates in adolescent athletes remain unclear. To compare the effects of Greek yogurt (GY) and whey protein (WP) supplementation on bone and inflammation markers in adolescent athletes throughout a competitive season. Athletes completed an initial control period on their habitual diets (weeks 0\u20128), followed by randomization to GY (n = 24; 15.8 \u00b1 1.1 y; 11 females) or WP (n = 23; 16.0 \u00b1 1.4 y; 10 females) for a 16-wk intervention (weeks 8\u201224). GY consumed 2 servings per day of 175 g GY (17 g protein); WP received an isonitrogenous WP supplement. Blood samples and body composition assessments were obtained at weeks 0, 8, 16, and 24. Procollagen type I N-terminal propeptide, insulin-like growth factor-1, and receptor activator of nuclear factor \u03baB ligand remained stable. Osteocalcin and osteoprotegerin showed sex-specific between-group differences: osteocalcin declined throughout weeks 0\u201224 in GY males, whereas osteoprotegerin declined during weeks 0\u201216 in GY females and was elevated at the end of the control period in WP females. C-terminal telopeptide of type I collagen and sclerostin showed intervention group-dependent, but not sex-dependent, differences. C-terminal telopeptide of type I collagen increased transiently from week 8 to week 16 and returned to baseline by week 24 only in GY. Sclerostin concentrations fluctuated, and at 24 wk, were not different from baseline in GY but were higher than baseline in WP. At week 16, interleukin (IL)-1\u03b2 increased in WP, and IL-6 decreased in GY. IL-10 and tumor necrosis factor \u03b1 increased during the control period and decreased with WP only in females. Increased protein intake, independent of source, was associated with modest, often sex-specific fluctuations in bone and inflammatory markers in adolescent athletes, potentially influenced by growth and training-related factors across the competitive season. This trial was registered at clinicaltrials.gov as NCT05922462.\n\nID: 41916224\nTitle: Effect of packaging-induced oxygen microenvironments on the viability and metabolism of Lactobacillus paracasei in yogurt.\nAbstract: This study developed stirred probiotic yogurt co-fermented with Lactobacillus paracasei MBH3-2 and evaluated the protective effects of packaging materials with different oxygen transmission rates (OTR) on yogurt during storage. The addition of Lactobacillus paracasei MBH3-2 shortened fermentation time, improved physicochemical properties, and promoted the accumulation of functional metabolites. Packaging OTR significantly influenced dissolved oxygen (DO) levels, which were negatively correlated with total viable counts, pH, water-holding capacity (WHC), sensory scores, and key metabolic indicators (P\u00a0<\u00a00.01). Maintaining low and stable DO helped preserve microbial viability and delay quality deterioration. In the PBM-packaged group, Lactobacillus paracasei MBH3-2 showed favorable metabolic adaptation, with early enrichment in Fatty acid and Purine metabolism, followed by activation of the TCA cycle, Glycolysis/Gluconeogenesis, and Biosynthesis of amino acids in later storage. These findings underscore the potential of PBM packaging to create a balanced storage microenvironment, providing a sustainable and functional strategy for probiotic dairy preservation.\n\nID: 41858095\nTitle: Influence of Stabilizers, Milk Proteins, and Heat Treatment on the Tribology and Rheology of Drinking Yogurt.\nAbstract: This study investigated the effects of protein substitution, stabilizer addition, and heat treatment conditions on the physicochemical properties of drinking yogurt. Milk proteins (sodium caseinate [NaCas], milk protein concentrate [MPC], and whey protein isolate [WPI]) were used to replace the protein in skim milk powder (SMP) at ratios of 10%, 20%, and 40% (w/w). Stabilizers (pectin, gelatin, and soluble soybeanpolysaccharide [SSPS]) were added post-fermentation, and their concentrations in the final yogurt were 0.2%, 0.4%, and 0.4% (w/w), respectively. Milk was heated under different conditions (75\u00b0C/20\u00a0min [75-Y], 85\u00b0C/15\u00a0min [85-Y], and 95\u00b0C/5\u00a0min [95-Y]). Replacing SMP WPI, especially at 40%, yielded smaller particle sizes and higher water-holding capacity (WHC), whereas MPC or NaCas increased particle size. All stabilizers enlarged particles, with pectin exhibiting the most pronounced effect due to bridging flocculation. Heat treatment at 85\u00b0C produced the smallest particle size and highest WHC, whereas 95\u00b0C and 75\u00b0C treatments resulted in larger particles and reduced WHC. Higher protein substitution levels generally reduced viscosity, with 40% WPI significantly reducing viscosity. Conversely, pectin addition generated the highest viscosity, and SSPS the least. The high viscosity of 75-Y corresponded to its larger particles and lower WHC. Tribological analysis indicated that increasing the proportion of protein substitutes reduced the coefficient of friction, and notably, a 40% WPI substitution significantly improved lubrication properties associated with the creaminess sensation. Pectin also induced a rapid friction drop, consistent with its high viscosity. Although friction curves were similar across heat treatment, the friction coefficients of 75-Y and 95-Y were lower than that of 85-Y at medium sliding speeds.\n\nID: 41855840\nTitle: Enhancing carotenoid bioaccessibility in food matrices using modified mango cotyledon starch microcapsules: Contribution to the recommended daily intake.\nAbstract: This study evaluated starch extracted from mango cotyledons as a wall material for microencapsulating a carotenoid-rich pumpkin suspension. The resulting microcapsules were incorporated into water, yogurt, and gelatin to develop carotenoid-fortified foods. The effects of wall material and matrix on carotenoid bioaccessibility during in vitro digestion and their contribution to the recommended dietary allowance (RDA) across age groups were assessed. Carotenoid content and bioaccessibility varied significantly with encapsulant type and matrix. The combination of ultrasound-modified and dual-modified starch improved carotenoid bioaccessibility up to 27% (20\u00a0mg/100\u00a0g) in water, 16% (27\u00a0mg/100\u00a0g) in gelatin and 8% (49\u00a0mg/100\u00a0g) in yogurt; providing enhanced encapsulation and stability. Yogurt yielded the highest bioaccessibility, likely due to lipid-protein interactions enhancing carotenoid stability under gastrointestinal conditions. A 200\u00a0mL serving of fortified yogurt could provide 26%-36% of adult and 39%-62% of child (ages 4-13) vitamin A RDA. Utilizing mango processing residues as wall materials offers a sustainable, value-added strategy for developing functional foods.\n\nID: 41854434\nTitle: Effect of low-dose irradiation of starter culture on fermentation and physicochemical properties of set-type yogurt.\nAbstract: This study investigates the effect of X-ray irradiation of starter culture (S. thermophilus and L. delbrueckii subsp. bulgaricus) on yogurt fermentation and quality. The starter cultures Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus were exposed to X-ray radiation using Xstrahl 320 medical irradiator with an energy of 150-320\u2009keV with a dose rate of 1.67\u2009cGy/s. The starter cultures were exposed to 60-120\u2009cGy radiation before fermentation and evaluation of their physicochemical properties during 14-day storage. The results showed that exposure of the starter culture to 60\u2009cGy, 80\u2009cGy, and 120\u2009cGy delayed yogurt fermentation by 6.5, 6, and 6\u2009hours, respectively, in comparison with the control yogurt (5.5\u2009h). The starter culture irradiated at 60\u2009cGy showed the lowest acidification rate and reduced post-acidification during refrigerated storage. This reduced acidification rate limited pH drift after fermentation, resulting in a more relaxed casein network and reduced syneresis. In contrast, higher irradiation doses (80 and 120\u2009cGy) selected metabolically robust cells capable of sustained acid production during storage. The pH of all the yogurt samples decreased slightly during storage, but not enough to weaken or destabilize the electrostatic interaction between the casein networks. Total viable bacterial counts decreased in all yogurt samples, with the 80\u2009cGy sample showing the lowest viability during storage. Irradiation increased fermentation time and decreased viability of the starter culture while simultaneously improving post-acidification and syneresis during storage. However, changes to the physicochemical properties of the yogurt samples were not significant enough to cause any negative impact on yogurt quality.\n\nID: 41850375\nTitle: Quorum sensing-driven metabolic reprogramming coordinates flavor formation in yogurt fermentation.\nAbstract: Interactions mediated by quorum sensing critically influence metabolic coordination in lactic acid bacterial fermentations, yet the extent to which exogenous signaling molecules modulate flavor formation remains insufficiently defined. Here, a binary yogurt fermentation model comprising Levilactobacillus brevis 54 and Lacticaseibacillus casei 56 was employed to elucidate how externally supplied autoinducing peptides (AIP) and autoinducer-2 (AI-2) reprogram microbial behavior and flavor-associated metabolism. Targeted supplementation with strain-specific AIP (AGQYYINHR and AYFQT) significantly enhanced bacterial growth, with elevated viable cell counts closely associated with accelerated casein hydrolysis and increased accumulation of AA-derived metabolites. In parallel, exogenous AI-2 (24 \u03bcM) stimulated bacterial growth and activated the AI-2/LuxS signaling cascade, accompanied by increased transcription of luxS, plnB, and plnC. Metabolomic analyses revealed that AIP primarily modulated AA metabolic pathways, whereas AI-2 exerted broader regulatory effects spanning AA, carbohydrate, and central carbon metabolism, partly mediated through upregulation of the AI-2-associated enzyme MtnN. Integrated profiling of nonvolatile and volatile flavor compounds demonstrated that coordinated AIP- and AI-2-mediated signaling redirected metabolic fluxes toward flavor-active derivatives, leading to enhanced formation of alcohols, ketones, and organic acids that contribute to yogurt aroma. Collectively, this study delineates how parallel intraspecies and interspecies quorum-sensing pathways integrate to reshape metabolic networks during yogurt fermentation, providing mechanistic insight into signal-driven flavor modulation and a framework for the rational design of flavor-enhanced fermented dairy systems.\n\nID: 41849490\nTitle: Effect of bee pollen on viability of starter culture bacteria in probiotic yogurt.\nAbstract: It aims to produce probiotic yogurts with different amounts of bee pollen (0.5%, 1.5%, 3% and 6%). The effect of bee pollen on starter culture bacteria (Bifidobacterium spp., L. acidophilus, L. bulgaricus, and S. thermophilus) was analyzed during fermentation (42\u00b0C, 24 hours) and storage (4\u00b0C, 14 days). The microbiological properties were determined for food safety. The addition of bee pollen decreased the pH value during fermentation. The lowest mean count was in Bifidobacterium spp. (6.94 log CFU/g), followed by L. acidophilus (7.64 log CFU/g), L. bulgaricus (8.20 log CFU/g), and S. thermophilus (8.57 log CFU/g) at the end of fermentation. The pH values were decreased in all samples during storage. The viability of L. acidophilus and Bifidobacterium spp. was lower than 6 log CFU/g on the 14th day. L. acidophilus was 5.83 log CFU/g and 5.98 log CFU/g in control and yogurts with 0.5% bee pollen. Bifidobacterium spp. counts were 5.72 log CFU/g, 5.35 log CFU/g, and 5.27 log CFU/g in yogurts with 1.5%, 3%, and 6% bee pollen, respectively. If the results compared in total probiotic bacteria, all samples are following the codex (>6 log CFU/g). Yeast, mold, and coliform were not observed in the samples during storage.\n\nID: 41830445\nTitle: Developing Indigenous Plant-Enriched Yogurt to Enhance Iron Solubility-A Collaboration With Senegalese Women Farmers.\nAbstract: This study utilized collaborations with Senegalese women farmers to investigate the impact of lactic acid bacteria (LAB) fermentation of sorghum, baobab, and milk on nutritional and sensory qualities for plant-enriched yogurt. Using a simplex lattice mixture design, five samples of varying weight ratios of sorghum/baobab (17.5/32.5-47.5/2.5, w.b.) were prepared by mixing sorghum/baobab blend (50\u00a0g, w.b.), milk (500\u00a0mL), Lactobacillus bulgaricus species and Streptococcus thermophilus species, and fermenting at 40\u00b0C for 9 h. After only fermenting milk, one Control was prepared by adding sorghum/baobab (32.5/17.5). The samples were evaluated for pH, texture, LAB count, and iron solubility after simulated digestion. A total of 125 panelists, including 32 Africans, evaluated the samples flavored with bananas after fermentation, using a nine-point hedonic scale and check-all-that-apply (CATA) method. Data were analyzed using variance analysis, least significant difference test, agglomerative hierarchical clustering, and Fisher's exact test. All samples had a pH below 4.6 and a LAB count of 108, except for sample 17.5/32.5 (104), likely due to baobab's acidity hindering LAB growth. Fermenting sorghum, baobab, and milk together increased iron solubility by 64.1% compared to the Control. From the CATA results, sweet flavor and creamy mouthfeel increased overall liking, while tart flavor and gritty mouthfeel decreased liking. Cluster analysis showed that Africans favored samples with both less and more baobab equally (40/10, 25/25, overall liking of 6.8), while Caucasians preferred less baobab (40/10, overall liking of 4.8). Both clusters disfavored the Control (overall liking 6.0 and 4.1), which had the lowest instrumental texture consistency.\n\nID: 41829949\nTitle: The Effect of Yogurt Consumption on Body Fat Percentage in School-Age Children: A Quantile Regression Analysis.\nAbstract: Objectives: The objective of this study was to investigate the association between yogurt consumption and body fat percentage among Chinese children and to analyze the potential influence of factors such as sex, pubertal stage, and physical activity level on this association. Methods: This study conducted a nationwide survey using multi-stage stratified random sampling, including 48,305 children aged 6-17 years. Body fat percentage (BFP) was measured using bioelectrical impedance analysis (BIA). Daily yogurt consumption was adjusted using the density method (daily yogurt consumption = daily yogurt consumption \u00d7 1000/total energy consumption). The association between yogurt consumption and body fat percentage was analyzed using quantile regression, with covariates adjusted for participants' age, pubertal development stage, geographical region, total daily energy consumption, physical activity duration, annual household income, parental educational attainment, and consumption of other food categories. Results: Boys aged 6-10 years, 11-14 years, and 15-17 years had median daily yogurt consumptions of 28.6 g, 28.6 g and 21.4 g per day, with BFP values of 19.6, 19.5 and 17.5. Girls in the same age groups showed consumption of 28.6 g, 29.6 g and 28.6 g, with BFP values of 20.3, 26.4 and 31. The quantile regression results for boys showed that daily consumption of yogurt was significantly correlated with their BFP at the 0.25, 0.50, 0.75, 0.85 and 0.95 quartiles, with regression coefficients of -0.207, -0.300, -0.688, -0.570, and -0.465 after adjusting for potential confounders. For girls, there was a significant correlation in the 0.75 and 0.85 quartiles, with regression coefficients of -0.290 and -0.582, after adjusting for potential confounders. Conclusions: A significant inverse association was observed between yogurt consumption and body fat percentage, with notable differences between boys and girls. Further intervention studies are warranted to evaluate the long-term effects of incorporating yogurt into the diets of Chinese children and adolescents on body fat percentage and obesity risk.\n\nID: 41828410\nTitle: Integrated Untargeted and Targeted Metabolomics Reveals Distinct Bioactive Metabolite Profiles Between Probiotic Supplements and Yogurt.\nAbstract: Probiotics are widely consumed as health-promoting agents, with probiotic supplements (PS) and yogurt (YG) representing formulated products and fermented foods, respectively. Despite their broad consumption, systematic comparisons of their biochemical characteristics remain limited. In this study, integrated untargeted and targeted metabolomics approaches were applied to compare the comprehensive metabolite profiles of PS and YG. PS exhibited relatively higher levels of amino acids, dicarboxylic acids, and lysophospholipids, along with short-chain fatty acids such as acetate and propionate, and amino acid-derived bioactive metabolites, including \u03b3-aminobutyric acid, branched-chain hydroxy acids, indole derivatives, and \u03b3-glutamylpeptides. In contrast, YG showed higher relative abundances of carbohydrates, acylcarnitines, sphingolipids, and bioactive metabolites such as butyrate, creatine, carnitine, and orotic acid. Based on these metabolomic differences, 27 PS-specific and 17 YG-specific marker metabolites were identified. To explore their functional relevance, in vitro antioxidant and antiglycation activities were evaluated. PS exhibited significantly higher antioxidant and antiglycation activities than YG, which were positively correlated with amino acids and indole derivatives. Indole-3-acrylic acid, indole-3-acetic acid, and indole-3-propionic acid showed antiglycation activity and were identified as PS-specific bioactive marker metabolites. These findings reveal the distinct biochemical characteristics of PS and YG and highlight potential bioactive candidate metabolites that may contribute to their functional differences.\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.

This study examined the impact of three probiotic combinations-Y1 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus rhamnosus), Y2 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus paracasei) and Y3 (Lactobacillus plantarum and Bifidobacterium sps.)- on microbial dynamics and metabolite formation in lupin-oat yoghurt analogues, using unfermented milk analogues as a control. Samples were assessed during fermentation and throughout 28 days of refrigerated storage (4 \u00b0C) using microbial enumeration, 16S rRNA sequencing, acidification profiling, and mass spectroscopy-based metabolomics. Fermentation increased volatile compounds, from 23 in the control to 28 (Y1), 41 (Y2) and 54 (Y3). Probiotic combination Y3 exhibited the most complex and stable aroma profile, enriched in pleasant volatiles such as butanoic acid, phenylacetaldehyde, and butyl esters which effectively masked off-flavours like hexanal and heptanal. Microbiota analysis revealed stable formulation-specific communities, with- Streptococcus dominating in yoghurt analogues Y1 and Y2, and Bifidobacterium prevailing in yoghurt analogues Y3. KEGG-based functional prediction linked these transformations to microbial enzymatic activities within metabolic pathways. Notably, Bifidobacterium dominance in Y3 facilitated enhanced ester biosynthesis and conversion of aldehydes to acids, highlighting the \"bifid shunt\" as a key contributor to flavour enhancement. This integrated multi-omics approach highlights the critical role of targeted probiotic selection in modulating fermentation biochemistry, microbial ecology, and sensory attributes in plant-based lupin-oat yoghurt analogues. Notably, Bifidobacterium-driven fermentation in Y3 offers a promising strategy for improving the flavour profile and consumer acceptance of lupin-oat yoghurt analogues.\n --- END ACTUAL ABSTRACT FOR 42300034 ---\n\n- ERROR: You cited ID: 42543341 for the quote: \"In conclusion, psoralen directly targets and activates the PINK1/Parkin pathway to mediate mitophagy, clear damaged mitochondria, improve the oxidative stress microenvironment...\"\n FACT: Ellipses (...) are strictly forbidden.

An oxidative injury model in MC3T3-E1 cells was established with 200 \u03bcmol\u00b7L~(-1) H_2O_2. The experiment was conducted with four groups: normal, model, psoralen, and inhibitor groups. Cell viability and proliferation were assessed by the CCK-8 assay and EdU incorporation assay, respectively. Apoptosis was analyzed by Annexin V-FITC/PI double-staining flow cytometry. Mitochondrial membrane potential was evaluated with the JC-1 probe, and reactive oxygen species(ROS) levels were measured by the DCFH-DA probe. Early osteogenic differentiation markers and late mineralized nodule formation were observed by alkaline phosphatase(ALP) staining and alizarin S staining, respectively. Transmission electron microscopy was employed to examine mitochondrial ultrastructure changes. Immunofluorescence staining and Western blot were employed to determine the expression levels of PINK1, Parkin, p62, Runt-related transcription factor 2(Runx2), and Osterix. Molecular docking and 100 ns molecular dynamics simulations were conducted to validate the binding mode and stability of psoralen with PINK1. The results showed that psoralen ameliorated H_2O_2-induced cell damage in a concentration-dependent manner, with the optimal concentration being 80 \u03bcmol\u00b7L~(-1). Psoralen significantly promoted cell proliferation, upregulated the expression of Runx2, Osterix, PINK1, and Parkin, enhanced mitochondrial membrane potential, increased mitophagy levels and osteogenic differentiation capacity, and enlarged mineralized nodule area. Simultaneously, it inhibited apoptosis, reduced intracellular ROS content, and downregulated the expression of autophagy substrate p62. Molecular docking results showed that the binding energy between psoralen and PINK1 was-7.024 kcal\u00b7mol~(-1), and 100 ns molecular dynamics simulations further confirmed the structural stability of the formed complex with persistent hydrogen bond interactions. In conclusion, psoralen directly targets and activates the PINK1/Parkin pathway to mediate mitophagy, clear damaged mitochondria, improve the oxidative stress microenvironment, promote the expression of osteogenic marker proteins and mineralization, thereby enhancing osteogenic differentiation of MC3T3-E1 cells, providing a new target and candidate drug for the prevention and treatment of osteoporosis.\n --- END ACTUAL ABSTRACT FOR 42543341 ---\n\n- ERROR: You cited ID: 42311683 for the quote: \"HS can disrupt intestinal tight junctions and weaken the barrier function of the gut, leading to what is commonly described as a 'leaky gut.'\"\n FACT: Strict Misquote Detected!

When people are exposed to high-temperature environments for a prolonged period, especially during intense physical activity, the condition may progress to HS. HS is an acute and potentially fatal disorder that can deteriorate rapidly if not treated in time. The intestine appears to be particularly vulnerable during HS. HS can disrupt intestinal tight junctions and weaken the barrier function of the gut, leading to what is commonly described as a \"leaky gut.\" Once this barrier is compromised, microbial products such as lipopolysaccharides can enter the bloodstream. These molecules may then activate immune cells, promote excessive cytokine release, and eventually drive a systemic inflammatory response. In severe cases, this inflammatory process can develop into systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Current evidence increasingly suggests that intestinal injury is not simply a secondary result of HS. Rather, it may serve as an important early event in the development and progression of the disease. Still, it should be noted that much of the available evidence comes from preclinical studies, and strong clinical confirmation is still limited. Probiotics have attracted attention because they may help reduce the occurrence and severity of HS by maintaining gut microbiota balance and regulating intestinal immune responses. However, since most supporting data are still derived from animal experiments, their protective effects in humans need to be interpreted carefully. Another point worth emphasizing is that the gut is not working alone. Through gut-organ communication networks, the intestinal microbiota can interact with distant organs, including the liver, lungs, and brain. These gut-liver, gut-lung, and gut-brain axes may help explain how HS leads to injury beyond the intestine itself. In this review, we summarize current findings on how modulation of the gut microbiota may improve intestinal thermotolerance and strengthen barrier function, with the aim of providing useful insights for the prevention and treatment of HS in clinical practice.\n --- END ACTUAL ABSTRACT FOR 42311683 ---\n\n- ERROR: You cited ID: 42530815 for the quote: \"Supplementation with 100 mg/L LFRO is a natural drinking water supplement that improves feed efficiency and gut microbial balance in yellow-feathered chickens exposed to chronic tropical heat stress.\"\n FACT: Strict Misquote Detected!

This study evaluated the effects of Lactobacillus plantarum 1582-fermented red onion bulb extract (LFRO), supplied through drinking water, on growth performance, cecal microbiota, and excreta gas emissions in heat-stressed yellow-feather chickens. A total of 300 one-day-old male Rilai chicks were assigned to four treatments in a completely randomized design with five replicate pens of 15 birds each: unsupplemented control or LFRO at 25, 50, or 100\u00a0mg/L in drinking water. Birds were reared for 70 days under natural chronic tropical heat stress, with the temperature-humidity index predominantly within the severe-to-very severe range (28.9-31.1). Supplementation with 100\u00a0mg/L LFRO increased final body weight and body weight gain, reduced feed intake, and improved feed conversion ratio over the whole trial. The European Production Efficiency Index and Broiler Performance Efficiency Factor were also highest in the 100\u00a0mg/L group. Cecal 16\u00a0S rRNA sequencing showed no major changes in alpha- or beta-diversity, but several selected bacterial genera were modulated. LFRO at 50 and 100\u00a0mg/L reduced ammonia emission from excreta, whereas the other measured gases were not affected. This study shows LFRO at 100\u00a0mg/L is a natural drinking water supplement that improves feed efficiency and gut microbial balance in yellow-feathered chickens exposed to chronic tropical heat stress.\n --- END ACTUAL ABSTRACT FOR 42530815 ---\n\n- ERROR: You cited ID: 42543326 for the quote: \"R. palmatum has been shown to preserve the integrity of the alveolar-capillary barrier and to suppress excessive neutrophil activation...\"\n FACT: Ellipses (...) are strictly forbidden.

This type of disease is often triggered by multiple factors such as infection, sepsis, trauma, or inhalation injury, and the pathological process involves multiple sections including inflammatory cascade reactions, oxidative stress imbalance, abnormal activation of immune cells, and increased pulmonary microvascular permeability. Owing to their complex pathogenesis and high mortality, available clinical therapeutic approaches remain limited. Therefore, the development of safe and effective therapeutic agents to attenuate ALI has become a major focus of current research field. As a TCM, Rheum palmatum has a long history of use in clearing heat and toxins, purging the bowels, and regulating systemic inflammatory responses. In recent years, increasing attention has been paid to its therapeutic effect in ALI. RESULTS:: show that R. palmatum and its major bioactive anthraquinones, such as emodin and rhein, exert protective effects through multi-target and multi-pathway mechanisms. These mechanisms mainly include inhibition of inflammatory signaling pathways such as nuclear factor-\u03baB(NF-\u03baB), mitogen-activated protein kinase(MAPK), and NOD-like receptor protein 3(NLRP3) inflammasome, attenuation of oxidative stress response, activation of the nuclear factor erythroid 2-related factor 2(Nrf2)-mediated antioxidant defense system, regulation of programmed death in immune cells including macrophages, improvement of immunometabolic status, modulation of macrophage polarization and the gut microbiota as well as the gut-lung axis, and so on. In addition, R. palmatum has been shown to preserve the integrity of the alveolar-capillary barrier and to suppress excessive neutrophil activation and the overformation of neutrophil extracellular traps(NETs), thereby reducing inflammation amplification effect and the risk of immune microthrombi. This paper summarized the action mechanisms and research progress of R. palmatum in the treatment of ALI, aiming to elucidate the unique advantages of R. palmatum anthraquinones in intervening in the complex pathological processes of ALI through systemic regulatory networks and to provide a solid theoretical basis for the research and development of innovative R. palmatum-based medicines and their clinical combination medication.\n --- END ACTUAL ABSTRACT FOR 42543326 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Exopolysaccharide (EPS) production is a common feature of microbial carbohydrate metabolism during fermentation; however, glucan-type EPS produced by Bacillus species in fermented vegetable systems remain insufficiently characterized.\" (Source: 42533008)\n- \"This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy.\" (Source: 42212401)\n- \"Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways.\" (Source: 42280098)\n- \"Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application.\" (Source: 42543301)\n- \"Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression.\" (Source: 42536279)\n- \"KH caused a significant, dose-dependent downregulation of ACE2 gene expression in kidney-derived Vero E6 cells after 24 h of treatment, whereas SDC reduced ACE2 gene expression in lung-derived A549-ACE2-TMPRSS2 cells after 72 h.\" (Source: 42033495)\n- \"MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms.\" (Source: 42544276)\n- \"This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation.\" (Source: 41932000)\n- \"Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain.\" (Source: 42438036)\n- \"Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways.\" (Source: 41936926)\n- \"Microbial translocation has long been viewed as a nonspecific consequence of gut barrier failure in critical illness, with downstream effects attributed primarily to the host immune response.\" (Source: 42304659)\n- \"Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits.\" (Source: 42009106)\n- \"Collectively, these findings suggested that Scutellariae Radix ameliorated AS by suppressing pyroptosis in arterial tissues, attenuating inflammation, and improving lipid metabolism via regulating the NLRP3/caspase-1/GSDMD signaling pathway.\" (Source: 42543314)\n- \"The collective phenotypes broadly reflect the metabolic profile of DS.\" (Source: 42544450)\n- \"The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways.\" (Source: 42542543)\n\n\nINSTRUCTION: Study the actual abstracts provided.

"rawResponse": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. 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\"What is the core mechanism that Almased uses to improve metabolism and liver function and can the mechanism be repurposed as a therapeutic in neurodegenerative disease via the gut-brain axis?\"\n\nThe provided literature contains no mention of the product \"Almased.\" Consequently, no core mechanism for this specific agent can be established, nor can its efficacy in metabolic or liver function be evaluated using the context. However, the provided literature extensively documents gut-brain axis mechanisms\u2014such as the modulation of intestinal permeability, the suppression of proinflammatory signaling, and the activation of metabolic pathways like the PI3K/Akt/Nrf2 or AMPK-orexin axis\u2014that are currently being repurposed as therapeutic targets in neurodegenerative diseases.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe claim concerning \"Almased\" is unsubstantiated by the provided literature. The investigation focuses on whether metabolic modulators identified in the text (e.g., bioactive plant extracts, metabolites like \u03b2-hydroxybutyrate, or specific fermentation products) can be repurposed as neuroprotective agents via the restoration of intestinal barrier integrity and modulation of gut-brain signaling, a valid scientific inquiry supported by the text.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent research suggests that systemic metabolic health is fundamentally coupled to gut barrier integrity. Pathological increases in intestinal permeability, often termed \"leaky gut,\" allow microbial products to enter systemic circulation, driving chronic inflammation that extends to the central nervous system. \"Microbial translocation has long been viewed as a nonspecific consequence of gut barrier failure in critical illness, with downstream effects attributed primarily to the host immune response.\" This translocation of bacterial toxins activates systemic inflammatory circuits. \"Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits.\" \n\nTherapeutic strategies increasingly focus on repairing this barrier to mitigate neurodegeneration. Agents that stabilize the intestinal lining, such as plant-derived exosome-like nanoparticles, have shown potential. \"MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms.\" Similarly, metabolic signaling molecules can bridge the gut-brain gap: \"Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways.\" The integration of these pathways suggests that metabolic interventions can indeed improve neuro-metabolic outcomes by shielding the brain from peripheral inflammatory signals originating in the gut.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The gut-brain axis is now considered a key target for treating neuroinflammation; systemic inflammation originating in the intestine spreads to the brain, contributing to neurodegenerative disorders.\n* \"Truly\" degraders represent a novel class of dual-mechanism molecules that engage both ubiquitin-independent and ubiquitin-dependent degradation pathways to eliminate disease-relevant proteins.\n* In situ dextran synthesis by lactic acid bacteria is an emerging biothickening strategy used to improve the texture of non-dairy yogurt alternatives while considering clean-label functional food trends.\n* High-protein yogurt can drive distinct microbiome shifts in older adults, specifically increasing the abundance of *Coprococcus*, potentially conferring gut health benefits.\n* Certain natural compounds, such as rhubab (RR), restore intestinal barrier function while reprogramming the IDO-1-dependent TRP-KYN metabolic pathway to attenuate neuroinflammation.\n* Fermentation of ginseng by specific probiotics enriches protopanaxadiol (PPD)-type ginsenosides, which can seal the gut and reset redox homeostasis for precision geroprotection.\n* The \"bifid shunt\" facilitated by *Bifidobacterium* dominance is a key contributor to flavor enhancement in fermented plant-based products.\n* The PI3K/Akt pathway acts as a functionally necessary mediator of neuroprotection for natural alkaloids against cerebral ischemia/reperfusion injury.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n\n1.

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals."

We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis. Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection."

Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis."

Mela Rosa Marchigiana Preserves Intestinal Barrier Integrity and Confers Neuroprotection in a Gut-Brain Axis Co-Culture Model.\nAbstract: The gut-brain axis is a key target in neuroinflammatory disorders. We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference. These findings suggest MRME as a promising nutraceutical candidate for gut-brain axis dysregulation."

"abstract_text": "ID: 42528699\nTitle: Gut-brain axis mechanisms of remote brain dysfunction after traumatic spinal cord injury: immune inflammation, the vagus nerve, and neuroendocrine pathways.\nAbstract: Traumatic spinal cord injury (SCI) has traditionally been regarded as a central nervous system injury mainly confined to the injured segment. However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation."

ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC. These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication."

Probiotic supplementation represents a microbiota-targeted nutritional strategy for functional constipation, but associated host-response signals remain incompletely understood. This single-center, randomized, double-blind, placebo-controlled trial enrolled 104 adults who met the Rome IV criteria for functional constipation. Participants received either Lactiplantibacillus plantarum Probio87 or placebo for 8\u202fweeks, followed by a 4-week post-intervention follow-up. The primary endpoint was weekly complete spontaneous bowel movements. Secondary outcomes included Rome IV symptom scores, PAC-QOL, HAMD-24, safety parameters, and exploratory whole-blood gene-expression profiles related to inflammation, immune regulation, neuroendocrine signaling, and gut motility. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300075360). Probio87 supplementation significantly increased weekly complete spontaneous bowel movements compared with placebo at Week 8 and Week 12. Improvements were also observed in Rome IV symptom scores, constipation-related quality of life, and HAMD-24 domains related to anxiety, sleep, and retardation.

This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility."

"abstract_text": "ID: 42529162\nTitle: Reframing brain aging: neuroinflammation as an interconnected network process.\nAbstract: Neuroinflammation has emerged as a central component of brain aging, shaping the balance between neural resilience and vulnerability to cognitive decline. Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health."

Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression.

"abstract_text": "ID: 42505396\nTitle: Mediterranean Diet and Neurodegenerative Diseases: Recent Advances from the Gut-Immune-Brain Axis to Multi-Omics-Guided Precision Nutrition.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD) are regarded as systemic illnesses, mainly characterized by long-term neuroinflammation, metabolic dysregulation and barrier dysfunction. All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice."

However, the underlying causes of psychiatric disorders in patients with IBD remain unclear, and effective treatment strategies have yet to be established.

Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications."

Bats despite diverse dietary habits, making them ideal models for studying hypoglycemic mechanisms. In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Compared with insectivorous bats, frugivorous bats exhibited significantly higher levels of amino acid-related metabolites under high-glucose stimulation. These included N-acyl amino acids, aromatic amino acid derivatives, and branched-chain amino acid metabolites, which were enriched significantly in pathways, such as alanine, arginine, and D-amino acid metabolism. Additionally, several known gut-brain axis (GBA) metabolites-such as neurotransmitters, bile acids, and short-chain fatty acids-exhibited strong host dietary and species specificity. Frugivorous bats were enriched in neurotransmitters and short-chain fatty acids associated with insulin regulation, whereas insectivorous bats exhibited relatively higher levels of bile acid metabolites. Overall, this study provides theoretical insights into the metabolic adaptations of frugivorous bats and the glucose-response strategies of insectivorous bats, offering new perspectives on metabolite-based therapeutic approaches to diabetes. \u73b0\u6709\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u624b\u6bb5\u4ecd\u7136\u6709\u9650\uff0c\u4e9f\u9700\u63a2\u7d22\u8840\u7cd6\u8c03\u63a7\u7684\u65b0\u673a\u5236\u3002\u8759\u8760\u5177\u6709\u9ad8\u5ea6\u591a\u6837\u5316\u7684\u98df\u6027\uff0c\u4e14\u666e\u904d\u8868\u73b0\u51fa\u8f83\u957f\u7684\u5bff\u547d\u7279\u5f81\uff0c\u8fd9\u4f7f\u5176\u6210\u4e3a\u7814\u7a76\u964d\u8840\u7cd6\u8c03\u63a7\u673a\u5236\u7684\u7406\u60f3\u6a21\u578b\u3002\u672c\u7814\u7a76\u5bf9\u4e94\u79cd\u8759\u8760\u5f00\u5c55\u4e86\u8179\u8154\u8461\u8404\u7cd6\u8010\u91cf\u8bd5\u9a8c\uff0c\u5176\u4e2d\u5305\u62ec\u4e09\u79cd\u98df\u679c\u6216\u98df\u871c\u8759\u8760\uff08\u9274\u4e8e\u6c34\u679c\u548c\u82b1\u871c\u5747\u5177\u6709\u8f83\u9ad8\u7684\u7cd6\u542b\u91cf\uff0c\u4e0b\u6587\u7edf\u79f0\u4e3a\u98df\u679c\u6027\u8759\u8760\uff09\u4ee5\u53ca\u4e24\u79cd\u98df\u866b\u8759\u8760\u3002\u91c7\u7528\u6db2\u76f8\u8272\u8c31-\u7535\u55b7\u96fe\u7535\u79bb-\u4e32\u8054\u8d28\u8c31\u6280\u672f\uff08LC-ESI-MS/MS\uff09\u5bf9\u9ad8\u7cd6\u523a\u6fc0\u4e4b\u4e0b\u8759\u8760\u8840\u6e05\u4e2d\u5171704\u79cd\u5df2\u77e5\u4ee3\u8c22\u7269\u8fdb\u884c\u4e86\u5b9a\u91cf\u5206\u6790\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u9ad8\u7cd6\u523a\u6fc0\u4e0b\uff0c\u4e0e\u98df\u866b\u8759\u8760\u76f8\u6bd4\uff0c\u98df\u679c\u8759\u8760\u4f53\u5185\u591a\u79cd\u6c28\u57fa\u9178\u76f8\u5173\u4ee3\u8c22\u7269\u6c34\u5e73\u663e\u8457\u5347\u9ad8\uff0c\u4e3b\u8981\u7c7b\u522b\u5305\u62ecN-\u9170\u57fa\u6c28\u57fa\u9178\u3001\u82b3\u9999\u65cf\u6c28\u57fa\u9178\u884d\u751f\u7269\u4ee5\u53ca\u652f\u94fe\u6c28\u57fa\u9178\u4ee3\u8c22\u7269\uff0c\u8fd9\u4e9b\u4ee3\u8c22\u7269\u663e\u8457\u5bcc\u96c6\u4e8e\u4e19\u6c28\u9178\u3001\u7cbe\u6c28\u9178\u548cD-\u6c28\u57fa\u9178\u4ee3\u8c22\u7b49\u901a\u8def\u3002\u6b64\u5916\uff0c\u591a\u79cd\u5df2\u77e5\u7684\u80a0-\u8111\u8f74\u76f8\u5173\u4ee3\u8c22\u7269\uff08\u5982\u795e\u7ecf\u9012\u8d28\u3001\u80c6\u6c41\u9178\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff09\u8868\u73b0\u51fa\u663e\u8457\u7684\u5bbf\u4e3b\u98df\u6027\u548c\u7269\u79cd\u6c34\u5e73\u7684\u7279\u5f02\u6027\u2014\u2014\u98df\u679c\u8759\u8760\u5bcc\u96c6\u4e86\u66f4\u591a\u7684\u4e0e\u80f0\u5c9b\u7d20\u8c03\u63a7\u76f8\u5173\u7684\u795e\u7ecf\u9012\u8d28\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff0c\u800c\u98df\u866b\u8759\u8760\u5219\u8868\u73b0\u51fa\u6c34\u5e73\u76f8\u5bf9\u66f4\u9ad8\u7684\u80c6\u6c41\u9178\u4ee3\u8c22\u7269\u3002\u603b\u4f53\u800c\u8a00\uff0c\u672c\u7814\u7a76\u4e3a\u63ed\u793a\u98df\u679c\u8759\u8760\u7684\u4ee3\u8c22\u9002\u5e94\u673a\u5236\u53ca\u98df\u866b\u8759\u8760\u7684\u8461\u8404\u7cd6\u5e94\u7b54\u7b56\u7565\u63d0\u4f9b\u4e86\u66f4\u591a\u7406\u8bba\u4f9d\u636e\uff0c\u5e76\u4e3a\u57fa\u4e8e\u4ee3\u8c22\u7269\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u89c6\u89d2\u3002."

Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk."

Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury."

Because increased dietary fat intake can both trigger IBS symptoms and promote LPS translocation in the gut, this study aimed to better understand how a turmeric formula (TF) affects fasting and postprandial LPS response, after a high-fat challenge in patients with IBS (primary outcome). Secondary outcomes included postprandial ApolipoproteinB48 (Apo-B48) and triglycerides (TG) as markers of chylomicron-mediated LPS translocation, as well as gastrointestinal (GI) symptoms and stool pattern. In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients."

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management."

We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts.

Xinqingning Tablet (XQNT) demonstrates neuroprotective potential in IS complicated by gut dysbiosis (GD), yet its mechanisms of GBA modulation remain unclear. A dual-hit IS-GD mouse model was established via fecal slurry transplantation and permanent middle cerebral artery occlusion (pMCAO) surgery. Gut function was evaluated by constipation indices and histopathological changes, while the neuroprotective efficacy of XQNT (0.36, 0.48, and 0.61 g kg\u207b\u00b9) was assessed via TTC staining, neurological deficit scores, cerebral water content, and Evans blue (EB) extravasation assays. Additionally, Western blot was employed to quantify blood-brain barrier (BBB) and inflammation-associated proteins. microRNA sequencing was used to screen the differentially expressed miRNAs. miR-126 expression levels were measured by RT-qPCR, while concentrations of LPS, IL-6 and IL-10 were determined by ELISA. Finally, mechanistic validation employed intravenous miR-126 agonism/antagonism coupled with phenotypic rescue experiments. XQNT conferred robust survival benefits, while concurrently ameliorating intestinal dysfunction and neurovascular injury. Mechanistically, XQNT elevated miR-126 expression, suppressing NF-\u03baB-driven neuroinflammation. Additionally, miR-126 agonism phenocopied XQNT efficacy, whereas miR-126 inhibition abrogated therapeutic benefits. This study provides early evidence that XQNT functions as a dual-target GBA modulator that alleviates IS with GD via regulation of the miR-126/NF-\u03baB axis. By simultaneously promoting barrier restoration and inflammatory resolution, XQNT offers a promising therapeutic approach that links regulation of the gastrointestinal system with cerebrovascular protection."

By utilizing plant-derived agents such as Magnolia biondii-derived exosome-like nanoparticles (MFELNs) or microbial-biotransformed ginsenosides (PPD), researchers have demonstrated effective suppression of neuroinflammatory signaling in the hippocampus and peripheral immune cells, thereby providing a viable strategy to manage neurodegenerative trajectories through the microbiota-gut-brain axis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the gastrointestinal barrier acts as a fundamental defense against systemic inflammation. As evidenced in the literature, barrier dysfunction leads to the translocation of endotoxins such as LPS, which serves as a potent trigger for the NLRP3 inflammasome and subsequent neuroinflammatory responses. Emerging evidence highlights that MFELNs, derived from *Magnolia biondii*, effectively mitigate colitis by suppressing inflammatory signaling and restoring intestinal barrier proteins. Similarly, the fermentation of ginseng to enrich protopanaxadiol (PPD) transforms it into a potent anti-aging agent that seals the gut and resets redox homeostasis. These agents function by modulating the gut-brain-liver axis, effectively acting as \"molecular bridges\" that prevent the chronic, low-grade systemic inflammation (inflammaging) associated with neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived exosome-like nanoparticles (PELNs) possess a phospholipid bilayer structurally homologous to mammalian cells, enhancing their bioavailability for drug delivery.\n* The gut microbiota serves as an active metabolic site for transforming herbal precursors (e.g., ginsenosides) into active, bioavailable neuroprotective agents.\n* Systemic inflammation in conditions like rheumatoid arthritis is directly linked to the entry of intestine-derived LPS into the bloodstream, establishing a clear gut-joint-brain connection.\n* Chronic fatigue syndrome and obesity-related anxiety share common mechanisms rooted in gut dysbiosis and HPA-axis hyperactivity.\n* Short-chain fatty acids (SCFAs) function as critical mediators in the microbiota-gut-brain axis by preserving blood-brain barrier integrity and modulating glial cell states.\n* The gut-liver axis acts as a key filter; when this filter fails, bile acid metabolism is disrupted, further exacerbating neuroinflammation.\n* Prebiotic interventions can restore the firmicutes/bacteroidota ratio, directly correlating with improved cognitive outcomes.\n* Microbial metabolites from fermentable fibers are essential for suppressing histone deacetylase-mediated neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

By systematically reviewing relevant domestic and international research, this paper elaborated on the multi-target molecular mechanisms underlying the antidepressant effects of puerarin, including the regulation of the gut microbiota-gut-brain axis, inhibition of neuroinflammation, promotion of neurotrophy and neurogenesis, amelioration of oxidative stress and mitochondrial function, modulation of neurotransmitters and the hypothalamic-pituitary-adrenal(HPA) axis, and epigenetic modifications. The paper further highlighted its synergistically therapeutic potential in comorbidity models such as diabetes with depression and post-stroke depression, as well as its application in compound compatibility and the current status of clinical translation research. Despite breakthroughs in emerging fields like the regulation of neural circuit plasticity, intervention in neuronal apoptosis, and modulation of non-coding RNA networks, the clinical application of puerarin is primarily limited by its pharmacokinetic drawbacks, such as poor water solubility and low bioavailability, coupled with a lack of high-quality clinical evidence. This paper aims to provide a theoretical basis for developing puerarin into a novel antidepressant by deeply analyzing the complex network of its mechanisms and evaluating its prospects for clinical translation.\n\nID: 42542289\nTitle: Differential effects of Lactobacillus casei in probiotic and paraprobiotic forms on behavioral performance, oxidative stress, neuroinflammation, and cholinergic dysfunction in a streptozotocin-induced model of sporadic Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, oxidative stress, neuroinflammation, and cholinergic dysfunction. Increasing evidence suggests that gut microbiota disturbances contribute to AD progression, encouraging the investigation of microbiota-modulating approaches such as probiotics and paraprobiotics. This study evaluated the effects of Lactobacillus casei probiotic and its thermally inactivated paraprobiotic on cognitive, behavioral, oxidative, cholinergic, and inflammatory alterations in a sporadic AD model induced by intracerebroventricular streptozotocin (STZ-ICV; 3\u202fmg/3\u202f\u03bcL/site) in female rats. From day 4, animals received daily oral treatment with probiotic L. casei (1\u202f\u00d7\u202f109\u202fCFU), paraprobiotic (100\u202fmg/kg), or saline for 14\u202fdays. Behavioral assessments of memory and exploratory activity were performed alongside biochemical analyses of oxidative stress markers, antioxidant defenses, acetylcholinesterase (AChE) activity, and neuroinflammatory parameters in central and peripheral tissues. STZ-ICV administration induced impairments in working and long-term memory, increased oxidative stress and neuroinflammation, elevated AChE activity, and promoted intestinal and behavioral alterations. Both probiotic and paraprobiotic treatments attenuated memory deficits, reduced lipid peroxidation, inhibited AChE activity, and decreased inflammatory markers. However, their effects differed in magnitude and tissue specificity. The probiotic mainly improved peripheral antioxidant defenses, whereas the paraprobiotic exerted broader neuroprotective effects, reducing cerebral oxidative stress, restoring non-enzymatic antioxidant levels in the hippocampus and colon, improving jejunal catalase activity, and attenuating hippocampal astrogliosis. These findings demonstrate that modulation of the gut-brain axis through L. casei-based interventions mitigates key pathological features of sporadic AD, with paraprobiotics emerging as a promising and stable alternative with enhanced neuroprotective potential independent of bacterial viability.\n\nID: 42542250\nTitle: Nanomedicine for epilepsy: Expanding beyond conventional drug targets.\nAbstract: Epilepsy remains a major neurological disorder characterized by unpredictable seizures and cumulative comorbidities that even endure with standard pharmacotherapy. Conventional antiepileptic drugs (AEDs) are constrained by two interrelated barriers: limited brain penetration due to the blood-brain barrier (BBB), which necessitates high systemic dosing and peripheral toxicity, and a narrow mechanistic focus on neuronal ion channels and synaptic receptors. This neuron-centric view overlooks non-neuronal drivers, such as neuroinflammation and BBB dysfunction, that sustain epileptogenesis and contribute to drug resistance in roughly one-third of patients. Nanomedicine addresses these limitations through a fundamentally different approach. Leveraging the unique advantages of nanocarriers, including facile synthesis, surface modification, and receptor-mediated BBB transcytosis, nanoparticles have evolved from passive delivery vehicles into intelligent, multifunctional therapeutic platforms that actively engage with disease biology. In this Perspective, we first delineate the inherent limitations of conventional AEDs in target selection. We then highlight how emerging nanomedicines are expanding the therapeutic target repertoire to include key non-neuronal nodes, with a focus on neuroinflammation and BBB repair. Finally, we offer a forward-looking perspective on two emerging frontiers: modulation of metabolic dysregulation and the microbiota-gut-brain axis, as well as the development of theranostic nanoplatforms that integrate real-time seizure monitoring with closed-loop intervention. Through this discussion, we aim to inspire a reorientation of nanomedicine strategies toward precision therapy for epilepsy.\n\nID: 42542073\nTitle: Gut microbiota and brain health: Disease-specific pathways and emerging therapeutic strategies.\nAbstract: The microbiota-gut-brain axis (MGBA) has emerged as a dynamic, bidirectional communication system linking the gastrointestinal tract and the central nervous system (CNS) through neural, immune, endocrine, and metabolic mechanisms. Increasing evidence indicates that alterations in gut microbial communities are associated with a wide range of neurological disorders; however, the strength of this association varies across diseases, and many mechanistic observations still rely predominantly on experimental models rather than human studies. This review provides an overview of current evidence regarding the role of the gut microbiota in maintaining CNS homeostasis, with particular emphasis on intestinal barrier function, immune modulation, vagal and enteric communication, and the generation of biologically active microbial metabolites, including short-chain fatty acids, bile acids, and neurotransmitter-related compounds. Studies in both clinical and experimental settings have reported disease-specific microbial signatures in conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, autism spectrum disorders, and amyotrophic lateral sclerosis. In parallel, microbiota-directed interventions-including probiotics, prebiotics, dietary approaches, fecal microbiota transplantation, and strategies targeting microbial metabolites-have produced encouraging findings in preclinical studies and early-stage clinical investigations. Nevertheless, considerable heterogeneity in study populations, experimental methodologies, and therapeutic protocols continues to limit the translation of these findings into routine clinical practice. Collectively, current evidence supports the MGBA as a valuable framework for understanding neurological diseases while underscoring the need for rigorously designed longitudinal studies and well-controlled clinical trials to define its therapeutic relevance better.\n\nID: 42539626\nTitle: Sodium oligomannate reduces cerebral infarction and improves neurological function through microbiota remodeling in MCAO/R rats.\nAbstract: Ischemic stroke is the second leading cause of death worldwide, characterized by high mortality and a narrow therapeutic window for thrombolysis. Gut microbiota dysbiosis and gliosis following ischemic stroke are key drivers of post-stroke neurological impairment. Sodium oligomannate (GV-971) is a low-molecular-weight acidic oligosaccharide that targets the gut-brain axis. It alleviates gliosis and improves cognitive dysfunction by remodeling gut microbiota in Alzheimer's disease. However, it is still unknown whether GV-971 has pharmacological activity against ischemic stroke. Here, we explore the efficacy of GV-971 on infarct volume, gliosis, blood-brain barrier integrity, gut microbiota composition, and post-stroke cognitive impairment (PSCI) using a middle cerebral artery occlusion/reperfusion (MCAO/R) model in male Sprague-Dawley rats. Administer medication before surgery for 4 consecutive days and once after surgery, after stroke 24-hour triphenyltetrazolium chloride (TTC) staining revealed that 0.3 mg/kg GV-971 significantly reduced infarct volume in ischemic brain tissue from 37.81\u00b12.391% to 13.30\u00b14.801% and neurological impairment score of GV-971 treatment significantly decreased from 11.50\u00b10.54 to 7.29\u00b11.47. After stroke 24-hour immunofluorescence analysis of glial activation confirmed that GV-971 significantly reduced central inflammatory responses. Western blot combined with Evans blue staining collectively demonstrated that after stroke 24-hour, GV-971 exerts a significant protective effect on the blood-brain barrier. In the gut, GV-971 reversed microbial dysbiosis, as revealed by shotgun metagenomics, enhanced intestinal barrier integrity, and suppressed colonic inflammation. Antibiotic depletion abolished GV-971's neuroprotective effect, while fecal microbiota transplantation from GV-971-treated donors restored protection, supporting a microbiota-dependent contribution. Furthermore, GV-971-treated rats subjected to MCAO/R exhibited significant improvements in motor and cognitive function. For example, on day 35, Y-maze test results indicated that GV-971 administered either before MCAO/R (pre-treatment) or during the perioperative period (co-treatment) increased spontaneous alternation rate from 60.95\u00b14.91% to 85.60\u00b16.32% and 85.64\u00b15.027%. On day 32, novel object recognition assay results indicated that GV-971 treatment increased new-object exploration from 0.2039\u00b10.03752 to 0.3991\u00b10.1122 (pre-treatment) and 0.5066\u00b10.06982 (co-treatment). On day 42, Barnes maze test results indicated that GV-971 treatment reduced the time required to locate the target hole from 76.45\u00b117.41s to 31.03\u00b120.75\u2009s and 33.37\u00b119.30\u2009s for pre- and co-treatment, respectively. Taken together, GV-971 demonstrated neuroprotective potential in experimental ischemic stroke.\n\nID: 42535497\nTitle: The significance of inflammation and biomarkers of neurodegeneration in essential tremor: a systematic review.\nAbstract: Essential tremor (ET) is one of the most prevalent yet mechanistically unresolved movement disorders. Although traditionally attributed to cerebellar dysfunction, accumulating evidence indicates the involvement of broader systemic processes, including neuroinflammation, immune dysregulation, and neurodegeneration. However, the role of inflammation in ET remains insufficiently defined, particularly regarding whether it constitutes a primary pathogenic mechanism or a secondary response. This systematic review aimed to comprehensively evaluate current evidence on inflammatory, immune- related, and neurodegeneration-associated biomarkers in ET. A structured search of PubMed, Scopus, and Web of Science identified relevant studies published between 2000 and March 2026. Thirty-two studies fulfilled the inclusion criteria. Across clinical and molecular investigations, the available evidence was highly heterogeneous and frequently inconsistent. No reproducible inflammatory profile has been established, and reported alterations in cytokines, acute-phase proteins, and hematological indices varied substantially across cohorts. Although selected cytokines were associated with tremor severity and cognitive impairment, these associations lacked consistency and specificity. Similarly, biomarkers of neurodegeneration, including neurofilament light chain and \u03b1-synuclein, demonstrated variable and non-disease-specific alterations. Emerging evidence suggests the involvement of integrative mechanisms encompassing blood-brain barrier dysfunction, impaired glymphatic clearance, and gut-brain axis interactions, although direct evidence in ET remains limited. Current evidence does not support inflammation as a primary driver of ET and instead indicates that inflammatory processes may act as context-dependent modulators within a multifactorial disease framework. Further well-designed longitudinal and multimodal studies are required to clarify the causal role of inflammation and its relationship to neurodegenerative mechanisms in ET.\n\nID: 42535369\nTitle: Integrating gut\u2011brain axis insights into bundled nutrition care for critically ill patients: From mechanisms to implementation (Review).\nAbstract: Critical illness induces a marked disruption of the gut\u2011brain axis, which is characterized by systemic inflammation and the rapid collapse of intestinal barrier integrity. These pathological shifts facilitate the translocation of pathogen\u2011associated molecular patterns, thereby driving neuroinflammation and exacerbating intensive care unit\u2011acquired syndromes such as delirium and muscular wasting. Although conventional nutritional strategies emphasize caloric and protein goals, emerging evidence has highlighted the necessity of modulating the host\u2011microbiome interface to preserve neurological and systemic homeostasis. The integration of fermentable fibers, probiotics and specialized lipid mediators into a standardized framework may effectively interrupt the self\u2011perpetuating cycle of dysbiosis and organ failure. The present review uniquely contributes to the field by integrating an implementation science framework for clinical bundle application and discussing artificial intelligence driven precision nutrition advances, which are topics that have not been comprehensively covered in the majority of previous reviews. Therefore, the present review bridges mechanistic insights with practical, scalable strategies to optimize nutritional care and improve recovery trajectories in patients with critical illness.\n\nID: 42534861\nTitle: Global research trends and hotspots of short-chain fatty acids in cognitive impairment: a bibliometric analysis based on two databases.\nAbstract: Short-chain fatty acids (SCFAs) have been widely investigated in research related to cognitive impairment, yet systematic bibliometric analyses focusing on their correlation remain relatively scarce. This study employed bibliometric analysis to objectively review relevant literature, identify key research contributors, and uncover emerging frontiers in the field. Relevant literature published from 2009 to 2025 was retrieved from the Web of Science Core Collection (WoSCC) and Scopus databases. Bibliometric analyses were performed using the Bibliometrix R package, VOSviewer, and CiteSpace software to evaluate research outputs and generate visualizations. A total of 425 eligible articles from WoSCC and 514 from Scopus were included. Annual publications on SCFAs and cognitive impairment showed a continuous upward trend from 2009 to 2025. China contributed the largest number of publications in this field, and an international collaboration network has been established, with Wenzhou Medical University (China) serving as the core collaboration hub. International Journal of Molecular Sciences was identified as a major publication platform, and Zhang, Xin was recognized as a core author in SCFA-cognitive impairment research. High-frequency keywords included \"gut microbiota,\" \"Alzheimer's disease,\" \"neuroinflammation,\" and \"gut-brain axis.\" In addition, recent research frontiers encompassed \"drug therapy,\" \"microbiology,\" and \"chemistry,\" revealing the core themes and trends of SCFA and cognitive impairment studies. This study conducted a comprehensive bibliometric analysis of the association between SCFAs and cognitive impairment, clarified the evolutionary trajectory of research themes, and identified potential future research directions. It revealed a developmental pattern whereby research in this field has gradually advanced from exploring basic correlations between diet and gut microbiota to in-depth investigations of pathological mechanisms, precise targeted interventions, and clinical translational applications. By systematically depicting the current research landscape, this study aims to provide guidance for subsequent investigations and fill critical knowledge gaps.\n\nID: 42532352\nTitle: Poricoic acid A alleviates depressive-like behaviors by targeting the gut microbiota-immune axis.\nAbstract: Poricoic acid A (PAA) is a bioactive triterpenoid from the fungus Poria cocos. Nevertheless, whether it exerts antidepressant-like effects and whether the gut microbiota and immune regulation are involved remain unknown. Male C57BL/6J mice were subjected to chronic unpredictable stress (CUS) and treated with PAA treatment. Behavioral tests were performed, and hippocampal damage was evaluated by H&E and TUNEL staining. Gut microbiota composition was analyzed using 16S rRNA sequencing, and hippocampal transcriptomic profiling was performed using RNA-seq, followed by immune cell infiltration, correlation, and functional enrichment analyses. PAA treatment eased CUS-induced depression- and anxiety-like behaviors. It also cut down hippocampal neuron damage and cell death. Besides, PAA fixed gut bacteria balance by lowering harmful germs like L. murinus and boosting good germs like A. muciniphila and L. reuteri. Hippocampal transcriptomic analysis revealed that PAA modulated immune cell infiltration by reducing M1 macrophages and restoring M2 macrophages, with significant correlations between gut microbial taxa and hippocampal immune-related gene expression. Functional enrichment analyses indicated that PAA regulates pathways related to synaptic plasticity, neuroinflammation, and neuronal development. qPCR and western blotting confirmed that PAA restored the hippocampal expression of key molecules involved in neuroinflammation (HSP90B1), synaptic plasticity (RPS6KB2 and IGF2BP2), and blood-brain barrier integrity (COL4A5) CONCLUSIONS: PAA alleviates depression-like Behaviors in CUS mice by remodeling the gut microbiota and modulating the hippocampal M1/M2 macrophage balance via the gut-brain axis. These findings support the potential of PAA as a prebiotic-like nutritional agent for major depressive disorder.\n\nID: 42530981\nTitle: Dietary plant polysaccharides as modulators of brain aging: mechanistic links to inflammaging, the gut brain axis and amyloid tau pathology.\nAbstract: Objectives: This review critically evaluates chemically characterized plant-derived polysaccharides (PS) as dietary modulators of brain aging, focusing on their structural features, gut-brain mechanisms and effects on neuroinflammation, amyloid pathology and tau-related pathways.Methods: Molecular, in vitro, preclinical and early human studies were critically examined. Evidence was assessed in relation to PS molecular weight, branching, charge, monosaccharide composition, purity, fermentability, dosage and associated non-carbohydrate constituents. Particular attention was given to gut microbiota modulation, short-chain fatty acid (SCFA) production, barrier integrity, immune signaling, microglial activation and neurodegenerative biomarkers.Results: Fermentable plant PS altered gut microbial composition and increased acetate, propionate and butyrate production in experimental models. These SCFAs may influence brain aging through FFAR2/FFAR3 signaling and histone deacetylase inhibition, thereby improving intestinal barrier function, regulating peripheral inflammation and modifying microglial responses. Direct anti-amyloid effects were supported mainly by in vitro studies, whereas evidence for tau modulation remained indirect and predominantly preclinical. Animal studies provided the strongest causal support, particularly through microbiota-transfer, antibiotic-depletion and receptor-pathway experiments. Human evidence was limited to associative studies and small fiber or prebiotic trials. Reported PS molecular masses ranged from about 10 kDa to more than 1,000 kDa, with preclinical doses of 50-500 mg/kg and human intakes of 5-15 g/day.Discussion: Plant PS are promising dietary modulators of brain aging but not established neurotherapeutics. Translation requires standardized fractions, control of co-extracted phenolics and proteins, dose-response studies and biomarker-rich clinical trials incorporating stool and plasma SCFAs, inflammatory markers, neurofilament light, phosphorylated tau, cognitive outcomes and neuroimaging measures.\n\nID: 42530574\nTitle: The gut-brain-mitochondria axis in type 2 diabetes-associated cognitive decline: mechanistic convergence, biomarkers, and therapeutic opportunities.\nAbstract: Type 2 diabetes mellitus (T2DM) is increasingly recognized as a major risk factor for cognitive impairment and dementia, extending beyond its traditional metabolic complications. Emerging evidence suggests that cognitive decline in T2DM arises from a complex interplay among gut dysbiosis, chronic inflammation, impaired insulin signaling, blood-brain barrier dysfunction, and mitochondrial abnormalities. The gut-brain-mitochondria (GBM) axis has recently emerged as an integrated mechanistic framework linking peripheral metabolic disturbances to central neurodegenerative processes. Within this axis, alterations in gut microbial composition and function promote intestinal barrier disruption, endotoxemia, and aberrant production of microbial metabolites, which collectively contribute to systemic inflammation, neuroinflammation, and neuronal insulin resistance. Mitochondria occupy a central position in this network by regulating cellular bioenergetics, redox homeostasis, calcium signaling, and neuronal survival. Mitochondrial dysfunction amplifies oxidative stress, impairs synaptic plasticity, disrupts adult hippocampal neurogenesis, and accelerates neurodegenerative signaling pathways associated with cognitive decline. Furthermore, bidirectional communication between gut-derived metabolites and mitochondrial pathways influences neuronal resilience and disease progression. This review synthesizes current evidence describing the mechanistic convergence of gut dysbiosis, mitochondrial dysfunction, and neuroinflammation in T2DM-associated cognitive impairment. We also discuss emerging biomarkers, including mitochondrial DNA copy number, circulating lactate, lipopolysaccharide, zonulin, and microbial metabolite signatures, that may facilitate early disease detection and patient stratification. Finally, we critically evaluate therapeutic strategies targeting the GBM axis, including microbiota-directed interventions, mitochondrial-targeted antioxidants, metabolic modulators, and lifestyle-based approaches. Understanding the integrated role of the GBM axis may provide novel opportunities for precision-based interventions to prevent or slow diabetes-associated cognitive decline.\n\nID: 42529162\nTitle: Reframing brain aging: neuroinflammation as an interconnected network process.\nAbstract: Neuroinflammation has emerged as a central component of brain aging, shaping the balance between neural resilience and vulnerability to cognitive decline. Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health.\n\nID: 42528699\nTitle: Gut-brain axis mechanisms of remote brain dysfunction after traumatic spinal cord injury: immune inflammation, the vagus nerve, and neuroendocrine pathways.\nAbstract: Traumatic spinal cord injury (SCI) has traditionally been regarded as a central nervous system injury mainly confined to the injured segment. However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation.\n\nID: 42528156\nTitle: Decoding Akkermansia muciniphila Effector Biology: From Microbial Molecules to Host Outcomes.\nAbstract: Akkermansia muciniphila is increasingly linked to host metabolic, immune, and neurobehavioral phenotypes, yet taxon-level associations are often inconsistent across studies and disease contexts. This review advances an effector-centered framework to explain how A. muciniphila acts through host-facing molecules, including outer membrane and secreted proteins such as Amuc_1100 (pilus-associated signaling, PAS) and P9, extracellular vesicles (EVs) and outer membrane vesicles (OMVs), and shed cell-envelope fragments and lipids. We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release. Key gaps include physiological dose realism, equivalence across colony-forming units (CFU) and protein or vesicle doses, strain and culture-condition dependence of effector expression, and limited human data for brain-relevant endpoints. Effector-defined preparations and engineered delivery systems may improve standardization and safety, but translation will require rigorous characterization, dose-response validation, and mechanism-linked biomarkers.\n\nID: 42526737\nTitle: Cannabinoid receptor-mediated modulation of the gut-brain axis under chronic stress: Neuroinflammatory mechanisms, microbial metabolites, and sexual dimorphism.\nAbstract: Chronic stress disrupts the gut-brain axis (GBA) through coordinated dysfunction of the intestinal barrier and of the vascular interfaces that protect the brain, fostering a neuroinflammatory state implicated in mood disorders, neuropsychiatric conditions, and chronic pain. This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility.\n\nID: 42524177\nTitle: Psychobiotic Effects of Postbiotics in Depression, Psychosis and Mania.\nAbstract: The gut microbiota significantly influences mental health through the gut-brain axis, modulating mood, cognition, and emotional regulation. While probiotics and prebiotics have been widely studied for their psychobiotic effects, postbiotics-metabolic byproducts of probiotics-represent an underexplored area with potential therapeutic applications. Understanding the role of postbiotics in mental health disorders, such as depression, psychosis, and mania, could lead to novel treatment strategies. This review examines the psychobiotic potential of postbiotics and their mechanisms of action. A systematic literature review was conducted to evaluate the effects of postbiotics on mental health conditions. We searched PubMed, Medline, EMBASE, and the Cochrane Library for English-language articles published between January 1, 2015, and January 1, 2025, using keywords such as \"postbiotic,\" \"paraprobiotic,\" \"depression,\" \"anxiety,\" and \"psychosis.\" A manual search supplemented the electronic search to ensure comprehensive coverage. Studies focusing on postbiotic effects on mood regulation, neuroinflammation, and neurotransmitter modulation were included. Postbiotics demonstrate promising psychobiotic effects in depression, psychosis, and mania. They modulate neurotransmitter levels, including serotonin and gamma-aminobutyric acid (GABA), and reduce neuroinflammation, contributing to improved mood and cognitive function. Additionally, postbiotics influence the hypothalamic-pituitary-adrenal (HPA) axis, enhancing stress response and emotional regulation. These findings suggest that postbiotics may serve as effective therapeutic agents for mental health disorders. Postbiotics offer significant potential as novel interventions for mental health conditions, with mechanisms involving neurotransmitter modulation and neuroinflammation reduction. Further empirical research is needed to elucidate their clinical applications and optimize therapeutic protocols. This review highlights the importance of postbiotics in advancing innovative strategies to improve mental health outcomes and well-being.\n\nID: 42497020\nTitle: Metabolic endotoxemia in metabolic and neurodegenerative diseases.\nAbstract: Metabolic diseases, which include obesity, type 2 diabetes, atherosclerosis, and metabolic dysfunction-associated steatotic liver disease (MASLD), are significant global health challenges. Patients with these conditions frequently exhibit gut dysbiosis and compromised gut barrier integrity, which lead to excessive translocation of Gram-negative bacterial lipopolysaccharide (LPS or endotoxin) from the gut lumen into the systemic circulation. This results in chronically elevated systemic LPS levels, a condition termed \"metabolic endotoxemia\". Gut-derived LPS may stimulate inflammatory responses and oxidative stress when it translocates and is recognized by host Toll-like receptor 4 (TLR4) and caspase-4/-5/-11. Metabolic endotoxemia is a primary trigger for the low-grade inflammation that promotes the development of metabolic diseases. Emerging evidence also indicates that metabolic endotoxemia acts as a key driver in the pathogenesis of neurodegenerative disorders, such as Alzheimer's disease, by promoting chronic neuroinflammation. In this review, we discuss: (1) the molecular structure of LPS that determines its bioactivity and its recognition by host cells, (2) host regulation of its bioactivity, (3) its translocation from the gut lumen into the systemic circulation, and (4) how metabolic endotoxemia contributes to obesity, type 2 diabetes, atherosclerosis, MASLD, and Alzheimer's disease. We conclude by exploring potential interventions aimed at preventing or mitigating metabolic endotoxemia by promoting LPS degradation and inactivation.\n\nID: 42474276\nTitle: Targeted \u03b2-Glucan-Veiled Oral Apremilast Nanotherapy Modulates Key Dysbiosis-Associated Gut Microbiota and Alleviates Ulcerative Colitis-Associated Anxiety, Depression, and Neuropsychiatric Behaviors.\nAbstract: Oral nanomedicines that modulate gut microbiota and gut-brain interactions are crucial for effectively treating inflammatory bowel disease (IBD) and associated psychiatric disorders, such as anxiety and depression. However, the underlying causes of psychiatric disorders in patients with IBD remain unclear, and effective treatment strategies have yet to be established. Herein, we developed oral gastroprotective \u03b2G@Apr-WPG NMs (\u03b2-glucan armored apremilast encapsulating tryptophan-poly(lactic-co-glycolic acid)-glutathione nanomicelles). This system effectively treats IBD and associated anxiety/depression by modulating the microbiota-gut-brain axis. \u03b2G@Apr-WPG NMs demonstrated gastroprotection enhances retention, and enables sustained release within the inflamed colon, enhances drug solubility, and inflammation-responsive apremilast release significantly improving oral therapeutic efficacy. Oral \u03b2G@Apr-WPG NMs administration outperformed free apremilast by restoring gut barrier integrity, reducing histopathological damage, and modulating microbial dysbiosis. Systemic inflammation and neuroinflammation were markedly suppressed. Notably, the \u03b2G@Apr-WPG NMs ameliorated anxiety- and depression-like symptoms, as well as cognitive deficits in colitis-induced mice, highlighting its therapeutic impact beyond the gut. Addressing reduced efficacy of conventional therapies, this multifunctional \u03b2G@Apr-WPG NMs platform offers safe, simple, and highly efficient therapeutic strategy integrating targets\u00a0intestinal inflammation, microbiota-gut-brain axis\u00a0modulation, in the pathogenesis of\u00a0IBD with comorbid neuropsychiatric disorders with confirmed safety.\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: 42389262\nTitle: 2-Pentadecyl-2-oxazoline alleviates anxiety-like behaviour and modulates the microbiota-gut-brain axis in obese mice.\nAbstract: A bidirectional relationship between obesity and anxiety disorders has been increasingly associated with neuroinflammation and dysregulation of the gut-brain axis. Here, we investigated the pharmacological effects of the N-palmitoylethanolamine oxazoline derivative 2-pentadecyl-2-oxazoline (C15OXA) in a mouse model of high-fat diet (HFD)-induced obesity, with particular attention to its central and peripheral mechanisms of action. Male C57Bl/6J mice were fed an HFD for 12 weeks and subsequently treated with C15OXA (30\u00a0mg\u00b7kg-1, p. o.) for 7 weeks. Behavioural, molecular, and microbiota analyses were performed to evaluate the effects of the compound. C15OXA significantly reduced anxiety-like behaviour in obese mice without affecting body weight, fat mass, or glucose tolerance. At the central level, C15OXA attenuated hippocampal neuroinflammation, as shown by reduced expression of COX-2, TLR4, NLRP3 and IL-1\u03b2. In parallel, C15OXA restored tight junction gene expression associated with blood-brain barrier integrity, and modulated unfolded protein response signalling. In addition, C15OXA enhanced markers of neurogenesis and synaptic plasticity. At the peripheral level, C15OXA treatment reduced colonic inflammation and improved gut barrier integrity. These effects were associated with a targeted reshaping of gut microbiota composition. In particular, C15OXA promoted the enrichment of butyrate- and menaquinone-producing bacteria, as taxa linked to beneficial metabolic functions. Overall, these findings suggest that C15OXA exerts anxiolytic-like effects associated with coordinated central and peripheral pathways involving the modulation of neuroinflammatory pathways, barrier integrity, and gut-brain axis signalling. This study provides novel pharmacological insight into the therapeutic potential of C15OXA for the treatment of obesity-associated neuropsychiatric disorders.\n\nID: 42346775\nTitle: GV-971 Ameliorates Chronic Restraint Stress-Induced Depression-like Phenotypes Accompanied by Reshaping of the Microbiota-Gut-Brain Axis.\nAbstract: Depression is increasingly linked to microbiota-gut-brain axis dysfunction, yet current monoaminergic antidepressants show limited efficacy. This study investigated the therapeutic potential and underlying mechanisms of GV-971, a marine-derived oligosaccharide, in a chronic restraint stress (CRS) mouse model. We first established that 8 h of daily restraint for 4-8 weeks induces a stable depression-like phenotype characterized by behavioral despair and significant reduction in peripheral monoamine neurotransmitters (5-HT and norepinephrine). GV-971 treatment robustly attenuated CRS-induced depression- and anxiety-like behaviors, restored hippocampal serotonin levels, reduced elevated plasma corticosterone concentrations, and ameliorated CRS-induced adrenal cortical hyperplasia. Mechanistically, GV-971 significantly suppressed neuroinflammation by inhibiting microglial hyperactivation in the prefrontal cortex and hippocampus. Concurrently, it repaired intestinal barrier dysfunction, evidenced by reduced permeability, restored mucosal integrity, and recovered goblet cell numbers. Crucially, integrated shot-gun metagenomics and plasma metabolomics revealed that GV-971 not only reshaped microbial taxonomy but also functionally recalibrated the gut ecosystem. It enriched beneficial taxa (e.g., Bifidobacterium pseudolongum, Bacteroides uniformis) and specific metabolic pathways, leading to increased short-chain fatty acids (valeric and caproic acids) and a significant reduction in plasma levels of tryptophan-kynurenine pathway metabolites, specifically the neurotoxic compounds kynurenine and quinolinic acid. Fecal microbiota transplantation (FMT) from GV-971-treated donors partially recapitulated the antidepressant and gut-protective effects in CRS recipients, confirming a causal role for the remodeled microbiota. Collectively, GV-971 exerts antidepressant effects by coordinately remodeling the gut microbiota, normalizing tryptophan and SCFA metabolism, restoring gut barrier integrity, and dampening central neuroinflammation, supporting its potential as a novel gut-brain axis-targeted therapy for depression.\n\nID: 42338576\nTitle: Exploring the gut-brain axis: dietary influences on Alzheimer's disease pathogenesis.\nAbstract: Alzheimer's disease (AD) is one of the most diagnosed neurodegenerative disorders worldwide and presents a significant challenge for both affected individuals and their caregivers. Alzheimer's disease is characterized by the accumulation of amyloid plaques and dysfunctional tau protein in the brain, along with the final development of dementia. Recently, in addition to the strongly developing ischemic etiology of AD, it is suggested that the gut and oral microbiota may also participate in the development of this disease. This involvement may stem from an unbalanced diet and the consumption of foods containing harmful chemical additives. An unhealthy diet can compromise the integrity of the gut barrier, facilitating the translocation of bacterial pathogens and leading to a pro-inflammatory T-cell response mediated by innate immune cells. This inflammatory response can disrupt systemic homeostasis and may contribute to neuroinflammation. The brain and gut interact through a complex network known as the \"gut-brain-microbiota axis,\" and emerging studies suggest that the intestinal microbiota and their metabolites may play a significant role in the pathogenesis of Alzheimer's disease. Moreover, these inflammatory mediators and microbial metabolites can reach the brain via the gut-brain axis, potentially exacerbating neurodegenerative processes. Preclinical and limited clinical evidence indicates that low-fiber diets are associated with alterations in intestinal microbiota composition, which may contribute to the onset and progression of Alzheimer's disease. This review aims to explore the potential connections between AD and the gut microbiome, emphasizing the significance of dietary factors in shaping these relationships. A comprehensive understanding of the interactions between the human microbiome and the brain, particularly in the context of diet and its ingredients, may enhance our understanding of AD etiology and inform the development of preventative strategies, through dietary modifications or therapeutic interventions. This area of research holds promise for identifying novel approaches to prevent or slow the progression of AD.\n\nID: 42325748\nTitle: Perioperative gut microbiota homeostasis and its interactions with anesthetic agents: recent advances.\nAbstract: The perioperative period is a critical and acute phase during which host-microbiota interactions play an essential role in determining susceptibility to anesthetic exposure and post-surgical stress. Immune homeostasis, gut barrier integrity, and metabolic regulation, as well as gut-brain and gut-liver axis, are highly dependent on the gut microbiota. However, this microbial ecosystem is disrupted during the perioperative period due to the combined effects of fasting, bowel preparation, surgical stress, hemodynamic alterations, and antibiotic and opioid use. Growing evidence has linked perioperative dysbiosis to a wide range of adverse outcomes, including infectious complications, anastomotic leakage, postoperative ileus, organ dysfunction, and perioperative neurocognitive disorders. Meanwhile, anesthetic and analgesic agents do not act in isolation from this ecosystem; rather, they engage in a bidirectional chemical interaction with the microbiota. These interactions can alter microbial structure and metabolite profiles, thereby influencing host metabolic processes, while microbial activity, in turn, affects drug disposition, immune response, and neuroinflammation. In this review, we first describe the vulnerability of gut microbiota homeostasis during the perioperative period and its associated clinical consequences. We subsequently elaborate on the mechanistic framework of anesthetic-microbiota crosstalk, highlighting pathways involving vascular, epithelial, immune and neural signaling. Then, we summarize emerging evidence demonstrating that different anesthetic and analgesic regimens generate discrete microbiota-metabolite signatures, which may underlie intersubject differences in postoperative recovery trajectories. Finally, we describe perioperative microbiota-targeted strategies, including probiotics and synbiotics, postbiotics and microbial consortia, nutritional optimization, and microbiome-based customization of anesthetic and analgesic protocols. Collectively, existing data suggest that preserving and actively modulating gut microbiota homeostasis represents a promising yet underexplored strategy for improving the safety of anesthesia and postoperative outcomes.\n\nID: 42323912\nTitle: Bioactive protopanaxadiol-enriched rice (DJ-PPD) exerts potent anti-inflammatory and antioxidant effects via dual regulation of NF-\u03baB/MAPK/Akt and NRF2/HO-1 signalling.\nAbstract: Protopanaxadiol (PPD) is a bioactive ginsenoside with significant anti-inflammatory potential; however, its low natural abundance and dependence on inefficient intestinal microbial bioconversion hinder pharmaceutical development. To overcome these supply and bioavailability constraints, we developed a metabolically engineered rice variety, DJ-PPD, capable of directly biosynthesizing the aglycone PPD. This study investigated the anti-inflammatory and antioxidant mechanisms of DJ-PPD extract in lipopolysaccharide (LPS)-stimulated BV2 cells. DJ-PPD treatment significantly reduced nitric oxide (NO) production, pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and the expression of iNOS and COX-2. Its efficacy surpassed conventional ginseng extract and was comparable to synthetic PPD (S-PPD). Mechanistically, DJ-PPD inhibited NF-\u03baB, MAPKs, and Akt phosphorylation while activating the NRF2/HO-1 antioxidant pathway. These findings demonstrate that DJ-PPD simultaneously inhibits pro-inflammatory cascades and reinforces intrinsic antioxidant defences. By effectively bypassing the need for gut microbiota metabolism, this genetically engineered rice represents a sustainable, bioavailable, and commercially viable multi-target therapeutic candidate for neuroinflammatory conditions.\n\nID: 42214609\nTitle: Treadmill exercise attenuates neuroinflammation in APP/PS1 mice via gut microbiota remodeling: Evidence from fecal microbiota transplantation.\nAbstract: Alzheimer's disease is associated with gut microbiota dysbiosis, intestinal barrier dysfunction, lipopolysaccharide (LPS) translocation, and neuroinflammation. However, it is unclear whether exercise-induced gut microbiota remodeling causally contributes to the neuroprotective effects of exercise in AD. Herein, APP/PS1 mice underwent 12\u00a0weeks of treadmill exercise, and fecal microbiota transplantation (FMT) was used to determine whether exercise-related benefits could be transferred to the recipient mice. Behavioral performance was assessed using the Morris water maze and open-field test. Gut microbial profiles were analyzed by 16S rDNA sequencing. Intestinal barrier integrity was evaluated using histology, AB-PAS staining, and tight-junction protein expression, while plasma and brain LPS levels were measured by enzyme-linked immunosorbent assay. Neuroinflammation was examined with immunofluorescence and Western blotting. It was found that treadmill exercise improved spatial learning, memory, and anxiety-like behavior in APP/PS1 mice. These benefits were partly reproduced in recipients of microbiota from exercised donors. Exercise also restored gut microbial diversity and composition, increased the abundance of taxa including Dubosiella and UBA1819, alleviated colonic injury, enhanced mucus secretion, upregulated ZO-1, Occludin, and Claudin-1, and reduced plasma and brain LPS levels. In parallel, exercise and FMT from exercised donors decreased brain TLR4 expression, attenuated microglial and astrocytic activation, and suppressed TLR4/NF-\u03baB signaling and downstream inflammatory cytokines. These findings indicate that treadmill exercise alleviates neuroinflammation in APP/PS1 mice, at least in part, through gut microbiota remodeling, improved intestinal barrier integrity, and reduced LPS-driven inflammatory signaling.\n\nID: 42207404\nTitle: Targeting Gut Microbiota by DPP-4 Inhibitors in Obesity: Mechanistic Insights and Therapeutic Implications.\nAbstract: Obesity is a complex metabolic disorder driven by factors such as chronic inflammation, insulin resistance, and significant alterations in the gut microbiota. Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications.\n\nID: 42195997\nTitle: Elaeagnus angustifolia L. Polysaccharide Alleviates High-Fat High-Fructose Diet (HFFD)-Induced Cognitive Impairment by Modulating the Gut-Liver-Brain Axis.\nAbstract: Cognitive impairment induced by a high-fat high-fructose diet (HFFD) is associated with gut-liver-brain axis dysfunction, yet whether polysaccharide intervention can modulate this axis to achieve cognitive rescue remains unexplored. This study investigated whether Elaeagnus angustifolia polysaccharide (EAP) is associated with protection against HFFD-induced cognitive decline by modulating this axis. Male C57BL/6J mice (n = 15/group) received Control, HFFD, HFFD + LEAP (300 mg/kg/day EAP), or HFFD + HEAP (800 mg/kg/day EAP) for 14 weeks. HEAP improved spatial memory, reducing escape latency by 31.2% on day 5 (p < 0.01). Multi-omics and histopathological analyses revealed that EAP was dose-dependently associated with restructuring of the gut microbiota, expanding Muribaculaceae and other SCFA-producers while suppressing pathobionts, thereby reversing the Firmicutes/Bacteroidota ratio from 1.71 to 0.94 (p < 0.01). Elevated cecal, hepatic, and cerebral acetate, propionate, and butyrate (p < 0.01) were associated with improved intestinal barrier integrity, attenuated systemic LPS translocation, and reduced hepatic inflammation and changes consistent with normalization toward control levels of PPAR\u03b1/\u03b3 signaling. These peripheral improvements were accompanied by changes in the hippocampus, where EAP suppressed IBA-1 microglial activation (from 4.5-fold to 2.1-fold of control, p < 0.01) and IL-6/TNF-\u03b1 signaling, changes in neurotransmitter balance (Glu, 5-HT, DA), and preserved postsynaptic density ultrastructure and PSD-95 expression (p < 0.01). These findings support a role for EAP in modulating the gut-liver-brain axis and may help prevent diet-related cognitive impairment, supporting its development as a microbiome-targeted functional food ingredient.\n\nID: 42177952\nTitle: Molecular pathways and clinical applications of probiotics as effective supporters of intestinal, neurologic, and cardiovascular health: A narrative review.\nAbstract: This narrative review aims to synthesize current knowledge on the molecular mechanisms and clinical applications of probiotics across three major health domains: intestinal, neurologic, and cardiovascular. Intestinal health: Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium lactis BB-12 reinforce epithelial integrity via upregulation of tight-junction proteins (occludin, claudin-1), attenuate inflammation through cytokine modulation (\u2191IL-10, \u2193TNF-\u03b1, IL-6), and restore eubiosis in conditions including IBS, constipation, and antibiotic-associated diarrhea. Neurologic health: \"Psychobiotic\" strains (e.g., L. rhamnosus JB-1, B. longum 1714, L. helveticus R0052 + B. longum R0175) modulate neurotransmitter synthesis (GABA, serotonin), dampen HPA-axis hyperactivity, and reduce neuroinflammation, yielding improvements in anxiety, stress resilience, cognitive function, and slowing brain-atrophy progression in MCI and Alzheimer's disease. Cardiovascular health: Meta-analyses of 30+ RCTs demonstrate that probiotic supplementation (notably L. acidophilus, L. plantarum, B. longum) lowers total and LDL cholesterol (-7 to -10 mg/dL) via bile-salt hydrolase activity, SCFA-mediated GPR signaling, direct cholesterol assimilation, and modestly reduces systolic (-2 to -4 mmHg) and diastolic blood pressure through anti-inflammatory pathways and improved endothelial function. Safety: While generally safe in healthy populations, rare adverse events (bacteremia, D-lactic acidosis, horizontal gene transfer) have been reported in immunocompromised or critically ill individuals, underscoring the need for individualized risk-benefit assessments and rigorous adverse-event surveillance. Probiotics exert strain-specific, multimechanistic benefits on gut barrier integrity, neuroendocrine signaling, and cardiometabolic regulation. To fully realize their therapeutic promise, future research must pursue large-scale, head-to-head clinical trials, integrate multiomics and precision-design approaches, and establish standardized frameworks for safety monitoring and personalized formulation.\n\nID: 42162800\nTitle: Limosilactobacillus reuteri ameliorates maternal immune activation-induced autism-like behaviors by reprogramming lipid biosynthesis in the gut epithelium.\nAbstract: Autism spectrum disorder (ASD) is frequently associated with gastrointestinal dysfunction and dysbiosis. Here, we demonstrate that the probiotic Limosilactobacillus reuteri (L. reuteri) ameliorates behavioral deficits and cortical dysfunction in offspring from a maternal immune activation (MIA) mouse model of ASD through two synergistic gut-brain pathways. Mechanistically, L. reuteri restores gut barrier integrity and attenuates inflammation by reprogramming colonic lipid metabolism toward cholesterol biosynthesis. Critically, cholesterol synthesis is indispensable for L. reuteri's therapeutic effects, as demonstrated by the fact that statin-mediated inhibition of cholesterol synthesis abolishes the benefits on gut barrier function and neurobehavior. Moreover, L. reuteri elevates serum levels of N-oleoyldopamine (OLDA), an endogenous lipid amide that crosses the blood-brain barrier and attenuates neuroinflammation. Exogenous OLDA administration alone is sufficient to attenuate neuroinflammation and ameliorate neurobehavioral and cortical dysfunction in MIA offspring. Together, these findings delineate a gut-brain axis mechanism by which L. reuteri counteracts MIA-induced autism-like behaviors, highlighting the therapeutic potential of targeting microbial-lipid crosstalk in ASD.\n\nID: 42149101\nTitle: The Copper-Gut-Brain Axis: A Triple Inflammatory Pathway Driving Neuroinflammation in Alzheimer's Disease.\nAbstract: Serum copper increases progressively with normal aging, yet its downstream consequences for the gut microbiome and neuroinflammation remain unexplored. Gut microbiota dysbiosis and elevated lipopolysaccharide levels are established features of Alzheimer's disease, and growing evidence indicates that this dysbiosis drives neuroinflammatory disease progression. Yet the upstream trigger initiating this dysbiosis remains unknown. We propose that age-related copper dyshomeostasis serves as this missing trigger. The redox-active copper content of ceruloplasmin increases across the adult lifespan, and copper is selectively toxic to anaerobic bacteria, preferentially affecting butyrate-producing genera including Faecalibacterium, Roseburia, and Coprococcus while sparing copper-resistant species. This selective toxicity is supported by animal studies demonstrating copper-induced elimination of butyrate producers with reversible gut barrier damage and by Wilson's disease cohorts showing consistent depletion of butyrate-producing genera due to elevated copper levels. The resulting dysbiosis creates a triple inflammatory pathway: butyrate loss compromises gut barrier integrity and removes histone deacetylase-mediated suppression of neuroinflammation; the increase of Gram-negative bacteria elevates lipopolysaccharide translocation through the compromised barrier; and impaired blood-brain barrier integrity reduces amyloid-\u03b2 clearance. These three insults trigger microglial activation through NF-\u03baB signaling, creating a 'triple hit' on a single transcription factor that may explain the magnitude of neuroinflammatory effects observed in Alzheimer's disease. This mechanism explains the increased acetate/butyrate ratio recently identified as a biomarker distinguishing Alzheimer's-related from non-Alzheimer's cognitive impairment (AUC 0.951), since copper disrupts microbial metabolic cross-feeding networks that convert acetate to butyrate. We present specific, falsifiable predictions that can be tested in human cohorts and propose copper as a novel upstream therapeutic target for Alzheimer's disease prevention.\n\nID: 42111070\nTitle: Microbiota and Guillain-Barr\u00e9 syndrome: role of microbial metabolites, biomarkers, and emerging therapeutic strategies.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is an acute autoimmune polyradiculoneuropathy that follows infection and is characterized by immune-mediated demyelination or axonal injury of the peripheral nervous system. While established triggers such as Campylobacter jejuni are well recognized, increasing evidence implicates the gut microbiota as a key modulator of immune responses relevant to GBS pathogenesis. The intestinal microbiota produces a diverse array of bioactive metabolites, including short-chain fatty acids (SCFAs), tryptophan-derived indoles, and neurotransmitter-like molecules, which influence immune tolerance, gut barrier integrity, and neuroinflammatory signaling. SCFAs, particularly butyrate, exert anti-inflammatory effects and support epithelial and blood-nerve barrier function. Microbial tryptophan metabolites regulate astrocyte and microglial activity via aryl hydrocarbon receptor (AHR) signaling, thereby restraining central and peripheral neuroinflammation. In contrast, dysbiosis-associated metabolites such as lipopolysaccharide (LPS) may enhance systemic inflammation, disrupt immune tolerance, and promote autoantibody production through mechanisms including molecular mimicry. Studies suggest that specific microbial taxa and metabolite signatures may serve as diagnostic or prognostic biomarkers in GBS, offering insights into disease susceptibility and progression. Microbiota-targeted therapeutic strategies are emerging as promising adjuncts to immunotherapy. Probiotics and prebiotics may restore beneficial microbial communities and rebalance immunoregulatory metabolite production, while host-directed metabolic interventions such as creatine supplementation may further support mitochondrial function, immunometabolic homeostasis, and neuroprotection. Fecal microbiota transplantation (FMT), though still experimental in GBS, has shown benefit in related neuroinflammatory disorders by reestablishing eubiosis and dampening immune activation. Future studies integrating metagenomic, metabolomic, and immunologic profiling in well-characterized GBS cohorts are essential to validate these findings and advance personalized microbiota-based interventions.\n\nID: 41966379\nTitle: Yeast \u03b2-glucan alleviates alcohol-related brain injury by restoring gut-brain axis homeostasis.\nAbstract: This study investigated the protective effects of yeast \u03b2-glucan (YBG) against alcohol-related brain injury (ARBI), with a focus on potential mechanisms mediated by the gut-brain axis. Our findings revealed that YBG supplementation significantly alleviated alcohol-induced anxiety-like behaviors and cognitive deficits in mice. In the brain, YBG mitigated oxidative stress, reduced neuroinflammation, and ameliorated neurotransmitter dysregulation. In the gut, YBG protected the alcohol-damaged intestinal barrier, upregulating the expression of tight junction proteins (Claudin-1, Occludin, and ZO-1) by 1.5- to 4.5-fold. Furthermore, YBG modulated the gut microbial community, markedly increasing the relative abundance of genera such as Akkermansia (from 0.13% to 4.3%) and Lactobacillus (from 0% to 0.89%), while suppressing alcohol-associated taxa including Alistipes (from 0.20% to 0.05%) and Colidextribacter (from 0.61% to 0.01%). These gut-level ecological changes were accompanied by significant shifts in the microbial metabolome, including elevated short-chain fatty acid levels and altered profiles of neuroactive amino acids, particularly L-tryptophan and L-tyrosine (which exhibited 2.9- and 2.7-fold increases, respectively). KEGG pathway analysis revealed that differential metabolites were primarily enriched in amino acid biosynthesis pathways. Correlation analysis showed strong positive associations among YBG-enriched bacteria, favorable metabolites, and markers of brain health. Together, these findings suggest that YBG's protective effects against ARBI are closely associated with the restoration of gut barrier integrity, restructuring the gut microbiota, and modulating microbial metabolism, which collectively correlate with the attenuation of neuroinflammation and oxidative stress.\n\nID: 41947394\nTitle: Goat Milk Fat Globule Membrane Supplementation Ameliorates Alzheimer Disease Cognitive Impairment by Modulating the Gut Microbiota.\nAbstract: Research has found Alzheimer disease (AD) is accompanied by cognitive dysfunction and gut microbiota imbalance. Goat milk fat globule membrane (GMFGM) derived from goat milk, is a membrane primarily composed of proteins and polar lipids that regulates the gut microbiota. However, its role in AD remains unclear. Therefore, we examined the neuroprotective effects of GMFGM in 5xFAD mice. Supplementation with GMFGM (400 mg/kg bw, 8 weeks) improved cognitive performance, reduced brain A\u03b2 deposition, alleviated neuroinflammation, and upregulated neurotrophic factors. Moreover, GMFGM preserved gut barrier integrity, lowered serum LPS levels, and reshaped gut microbiota composition, decreasing Alistipes, Dorea formicigenerans, and Duncaniella dubosii while increasing Stenotrophomonas. Further fecal microbiota transplantation validated the mechanism by which GMFGM ameliorates AD cognitive impairment by modulating the gut microbiota. These results indicate that GMFGM may rescue cognition by modulating the gut microbiota, alleviating gut damage, reducing LPS levels, and consequently inhibiting neuroinflammatory.\n\nID: 41901236\nTitle: Synergistic Therapeutic Effects of Tetrahydroberberine Combined with Protopanaxadiol on PCPA-Induced Insomnia in Rats: Involvement of the Microbiota-Gut-Brain Axis and Regulation of PI3K/AKT/AGE-RAGE Pathways.\nAbstract: Aim: This study investigated the synergistic therapeutic effects and underlying mechanisms of tetrahydroberberine (THB) combined with protopanaxadiol (PPD) on p-chlorophenylalanine (PCPA)-induced insomnia in rats. Methods: Rats were randomly divided into normal, model, diazepam, THB monotherapy, PPD monotherapy, and THB + PPD combination groups. Evaluations included the pentobarbital sleep test, HE staining, ELISA, 16S rRNA sequencing, metabolomics, and Western blot. Results: Results demonstrated that the THB + PPD combination exhibited significant synergistic effects compared with monotherapies: the combination shortened sleep latency by 56.2% (vs. 44.2% for THB alone and 20.7% for PPD alone) and prolonged sleep duration by 112.8% (vs. 70.2% for THB and 59.6% for PPD) relative to the model group, while effectively restoring body weight gain. Histologically, combined treatment significantly alleviated hippocampal neuronal damage and increased the number of intact neurons in the dentate gyrus. Molecularly, it upregulated brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) levels, restored neurotransmitter balance (serotonin, dopamine, and glutamate), suppressed overactivation of the hypothalamic-pituitary-adrenal (HPA) axis (reducing corticotropin-releasing hormone and corticosterone), and decreased pro-inflammatory cytokine expression. Gut microbiota analysis revealed that the combination restored microbial homeostasis (increasing beneficial bacteria such as *Lactobacillus*) and modulated the glycine-serine-threonine metabolic pathway. Mechanistically, THB + PPD synergistically activated the PI3K/AKT neurotrophic pathway (p-PI3K and p-AKT expression increased by 1.9-fold and 2.5-fold, respectively, vs. model), inhibited the AGE/RAGE pro-inflammatory axis (RAGE expression decreased by 31.8%), and enhanced blood-brain barrier integrity by upregulating tight junction proteins (ZO-1, Occludin). Conclusions: THB combined with PPD exerts synergistic anti-insomnia effects through multi-level regulation of the microbiota-gut-brain axis, neurochemical balance, and key signaling pathways, providing a promising foundation for developing safe natural product-based combination therapies.\n\nID: 41885697\nTitle: Beneficial effect of omega-3 fatty acids supplementation on leaky gut, inflammation and oxidative stress in propionic acid-induced autism in aged rats.\nAbstract: This study examined the effects of omega-3 fatty acids supplementation on gut barrier integrity, systemic inflammation, neurotrans-mission and oxidative stress, in an aged rat model of propionic acid (PPA)-induced neurotoxicity. Twenty-four aged male rats were divided into four groups: control, omega-3, PPA and PPA + omega-3. Serum cytokines, tight-junction proteins (TJP1), dopamine, serotonin, short-chain fatty acids (SCFAs), oxidative stress markers, and histopathology of the brain and small intestine were evaluated. PPA exposure significantly increased tumour necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-6 (IL-6) and reduced TJP1 expression, confirming gut barrier disruption and systemic inflammation. Omega-3 fatty acids supplementation selectively reduced IL-6 but did not reverse PPA-induced TNF-\u03b1 elevation or oxidative stress. CLDN2 expression increased in PPA + omega-3 rats, suggesting a compensatory but incomplete barrier response. Dopamine, serotonin, and SCFA levels showed upward trends with supplementation but were not statistically significant. Histological analysis demonstrated partial preservation of neuronal and intestinal structure in the PPA + omega-3 group. Overall, omega-3 fatty acids exerted modest anti-inflammatory effects but failed to fully restore oxidative balance or barrier integrity in aged rats, suggesting that omega-3 fatty acids may be more effective as a preventive rather than restorative intervention in ageing-related gut-brain axis disruption.\n\nID: 41874395\nTitle: Dysbiosis and the gut-brain axis impairment in the pathophysiology of Alzheimer's disease and related dementias: is 'pathobiome' an etiological element?\nAbstract: The gut microbiome plays a pivotal role in host metabolic, cardiovascular, and immune health. Increasing evidence also links it to aging-associated neurocognitive decline and neurodegenerative disorders, including Alzheimer's disease (AD) and related dementias. While the precise mechanisms of the gut-microbiome-brain axis remain incompletely understood, recent findings challenge the traditional view of AD as a disease confined to the central nervous system. Aging-associated gut dysbiosis, marked by loss of beneficial microbes, expansion of opportunistic pathogens, and reduced microbial diversity, can compromise intestinal barrier integrity, leading to 'leaky gut' and increased translocation of microbial components or pathogens into the circulation. These elements may cross a weakened blood-brain barrier, triggering neuroinflammation, amyloid-beta accumulation, tau hyperphosphorylation, and neuronal injury. Such pathobiome-driven inflammatory cascades may initiate or accelerate AD pathology, shifting the etiological perspective beyond the amyloid and tau hypotheses toward systemic and peripheral contributors. Our work and others' have identified distinct dysbiotic microbiome signatures in AD, supporting the possibility that AD pathogenesis may begin in the gut. Restoring microbial homeostasis through targeted interventions could attenuate neuroinflammatory and neurodegenerative processes, offering a novel preventive and therapeutic avenue. This emerging paradigm underscores the need for comprehensive, mechanistic, and longitudinal studies to define how aging-driven microbiome alterations influence the gut-brain axis and contribute to AD progression.\n\nID: 41870947\nTitle: Acupoint catgut embedding ameliorates laparotomy-induced cognitive decline in aged mice by restoring gut microbiota.\nAbstract: Postoperative cognitive dysfunction (POCD), a common neurological complication in elderly patients, significantly impairs recovery. Emerging evidence suggests the gut microbiota is involved in its pathogenesis. This study aimed to determine whether acupoint catgut embedding (ACE) could alleviate POCD by modulating the gut microbiota in aged mice after laparotomy. Eighteen-month-old male C57BL/6J mice underwent laparotomy on day 8 (excluding the Sham group). The ACE group received ACE treatment, while the anesthesia and surgery group served as surgical controls. The fecal microbiota transplantation (FMT)-ACE and FMT-AS groups received FMT from corresponding donors. Additional groups received oral indole-3-propionic acid (IPA) or vehicle-treated surgery. Hippocampal inflammation and blood-brain barrier proteins were assessed on day 9; cognitive function and intestinal markers on day 15. Cognitive function was significantly improved in the ACE, FMT-ACE, and IPA groups. ACE and FMT-ACE treatments specifically elevated fecal g-Clostridia_UCG-014 abundance and serum IPA levels. These changes were accompanied by suppressed hippocampal toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-\u03baB) signaling and proinflammatory cytokines [tumor necrosis factor alpha, interleukin (IL)-1\u03b2], together with elevated tight junction proteins (occludin, claudin-5). Furthermore, colonic aryl hydrocarbon receptor (AhR) and IL-22 were upregulated, while serum lipopolysaccharide and diamine oxidase were reduced. Accordingly, IPA treatment mirrored the key anti-inflammatory and barrier-protective effects. ACE alleviates POCD probably by modulating gut microbiota, specifically increasing g-Clostridia_UCG-014 abundance and metabolite IPA. These effects are potentially mediated by dual pathways: (a) suppression of neuroinflammation via TLR4/NF-\u03baB signaling, and (b) enhancement of gut barrier integrity via AhR/IL-22 axis. Our findings highlight the therapeutic potential of ACE in targeting the gut-brain axis for POCD management.\n\nID: 41837594\nTitle: Probiotic Interventions and Cognitive Performance: Insights from Recent Clinical Trials.\nAbstract: Probiotics, traditionally recognized for their role in gastrointestinal health, have recently been investigated for their potential influence on cognitive function through modulation of the gut-brain axis (GBA). This review summarizes the current clinical evidence and mechanistic insights on the role of probiotic interventions in mitigating cognitive decline and enhancing brain function, particularly in older adults and individuals with neuropsychiatric conditions. Cognitive impairments in the elderly, driven by neurodegeneration, vascular compromise, inflammation, and lifestyle factors, present significant challenges to public health systems. Several randomized controlled trials have demonstrated the beneficial effects of specific probiotic strains, such as Bifidobacterium breve A1, Lactiplantibacillus plantarum P8, and multispecies formulations, in improving memory, attention, and emotional regulation in populations with mild cognitive impairment, Alzheimer's disease, major depressive disorder, and schizophrenia. The cognitive improvements are linked to various mechanisms, including anti-inflammatory and antioxidant activities, modulation of neurotransmitter levels, maintenance of gut barrier integrity, and shifts in gut microbiota composition favoring beneficial taxa. However, not all interventions have yielded significant effects, suggesting strain-specific efficacy and interindividual variability in response. The present study discusses the limitations of existing studies and emphasizes the need for personalized approaches and rigorous, long-term clinical trials. Overall, probiotics show promise as adjunctive agents for preserving cognitive health and managing neurodegenerative and psychiatric disorders via modulation of the microbiota-GBA.\n\nID: 42522048\nTitle: Neuroinflammation in Alzheimer's and Parkinson's diseases: pathogenic mechanisms and therapeutic strategies.\nAbstract: Neuroinflammation is increasingly recognized as a key contributor and amplifier associated with the pathogenesis of Alzheimer's disease (AD) and Parkinson's disease (PD). Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression. This comprehensive review emphasizes that precise targeting of neuroinflammation represents a tractable strategy for developing effective disease\u2011modifying treatments for AD and PD.\n\nID: 42513192\nTitle: Intestinal and Blood-Brain Barrier Dysfunction in Lupus: Emerging Mechanisms and Modulation by Cinnamon.\nAbstract: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with evolving pathogenesis. Biological barriers, especially intestinal and blood-brain barriers (BBBs) with their tight junctions (TJ), are gaining attention in recent years as key players in disease initiation and progression. Among natural products targeting these barriers, cinnamon is emerging as a multi-targeted modulator of TJ. This narrative review integrates current evidence about gut and brain barrier dysfunction in lupus pathogenesis and highlights, on the basis of animal studies, the potential of cinnamon as a therapeutic candidate to restore barrier integrity and attenuate immune and neuroinflammation associated with lupus. Experimental evidence from lupus models supports the role of TJ disruption in disease pathogenesis. The alteration of TJ protein distribution in the epithelial barrier is correlated with an increased permeability of the intestinal barrier and changes in the microbiota composition in lupus, with consequent alteration in the gut-liver axis, liver inflammation and oxidative stress. Pre-clinical studies have demonstrated the restorative effect of cinnamon on gut TJ and permeability, microbiota and the gut-liver axis. Moreover, accumulating data suggest BBB disruption in lupus, correlated with neuroinflammation and behavioral disturbances. A murine model demonstrates the protective effect of cinnamon on BBB, especially via TJ localization, with the alleviation of neuropsychiatric alterations. Future perspectives should focus on cinnamon's effect on the gut-brain axis and translational studies.\n\nID: 42505396\nTitle: Mediterranean Diet and Neurodegenerative Diseases: Recent Advances from the Gut-Immune-Brain Axis to Multi-Omics-Guided Precision Nutrition.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD) are regarded as systemic illnesses, mainly characterized by long-term neuroinflammation, metabolic dysregulation and barrier dysfunction. All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice.\n\nID: 42488690\nTitle: A whole-transcriptome analysis of differentially expressed genes, transcripts, and transcript usage in blood samples from Parkinson's disease patients.\nAbstract: Parkinson's disease (PD) is a complex neurodegenerative disorder with diverse molecular signatures that extend beyond the central nervous system. Peripheral blood serves as a minimally invasive source of transcriptomic biomarkers reflecting systemic inflammation, mitochondrial dysfunction, lysosomal impairment, and disrupted RNA processing-key pathways involved in PD. Long-read RNA sequencing with Oxford Nanopore Technologies (ONT) offers unprecedented detail of full-length transcripts, alternative isoforms, and RNA modifications, enabling more accurate detection of disease-related transcriptional changes. We conducted high-throughput ONT long-read RNA sequencing on blood samples from 145 individuals, including PD patients and age-matched healthy controls. RNA libraries were prepared using a cDNA-based protocol optimised for high-accuracy PromethION sequencing. Transcriptomes were quantified with ONT-specific pipelines, and analyses of differential gene expression (DGE), differential transcript expression (DEX), differential transcript usage (DTU), and alternative splicing were performed using ONT-aware tools such as DRIMSeq, DEXSeq, and stageR. Pathway enrichment linked disease-related changes to mitochondrial, lysosomal, and vesicle-trafficking pathways. Our analysis identified highly significant PD-associated transcriptional signatures in peripheral blood (SNCA, VPS13C, LRRK2, GRN, STAU1, NPTN, PARK7). Long-read sequencing uncovered extensive isoform-level dysregulation, including novel transcript variants (e.g., BCL2L2-PABPN1, SQSTM1) in pathways relevant to PD, such as autophagy and endolysosomal trafficking. DTU analyses revealed shifts in isoforms of LRRK2 and GBA1, indicating widespread disturbances in RNA processing. Enrichment analysis showed activation of molecular pathways linked to neurodegeneration. This study provides the largest long-read blood transcriptomic dataset in PD to date, demonstrating that ONT sequencing can resolve isoform-level changes and reveal systemic molecular signatures of PD. Our findings support the development of blood-based RNA biomarkers and the establishment of long-read transcriptomics as a transformative approach for genomic pathology in PD.\n\nID: 42477453\nTitle: Microglial states revisited: from homeostasis to disease.\nAbstract: Microglia, the resident macrophages of the CNS parenchyma, are recognized as highly plastic, transcriptionally diverse cells whose phenotypes are moulded by development, region, sex, age, genotype and environment. Advances in single-cell and single-nucleus transcriptomics, chromatin accessibility profiling, and spatial multi-omics have negated binary frameworks of 'resting versus activated' or 'M1 (pro-inflammatory) versus M2 (anti-inflammatory)' and revealed a multidimensional state space that supports brain development, homeostasis and adaptive responses to perturbation. Building on the foundational concepts of the microglial sensome, homeostatic and disease-associated signatures, microglia exhibit transcriptomic state transitions in neurodegeneration, demyelination, infection and systemic inflammation. Moreover, a mechanistic framework for more 'hidden' microglial states\u00a0has emerged, in which latent programmes that appear homeostatic at baseline are revealed by challenges and are instructed through innate immune training or tolerance. We argue that these covert reprogrammed states, which are shaped by ageing, genotype, sex, location and prior exposures such as sepsis or viral infection, help explain interindividual variability in disease trajectories. We conclude by outlining priorities for unifying state annotation across species and modalities, and for translating state-resolved insights into biomarkers and interventions.\n\nID: 42470112\nTitle: Inflammatory proteins and cognitive decline in older black adults.\nAbstract: Strong evidence supports the role of low-grade systemic inflammation in neurodegeneration, including cognitive decline. Given the literature documenting chronic persistent inflammation in older Black adults, we investigated the association between circulating inflammatory proteins and cognitive decline in this high-risk population. We used data (n\u2009=\u2009642) from the Minority Aging Research Study (MARS) and the Rush Clinical Core, including plasma samples to assess circulating inflammatory proteins (Olink\u00ae Target-96 Inflammation) and cognition (global cognition and five cognitive domains) assessed annually following proteomics measurement using previously stored blood samples. Linear mixed-effect and latent class mixed models (age at blood draw for proteomics measurement, sex, and education-adjusted), and elastic-net regression were used. Statistical significance was determined using an FDR threshold of 10%. Participants (62.3 to 99.4 years) were mostly women (80.68%) with 15.1 years of education. In multivariable linear mixed-effect models, we found that higher levels of osteoprotegerin (OPG) and chemokine (C-C motif) ligand 23 (CCL23) were cross-sectionally associated with poorer global cognition (beta=-0.205 and beta=-0.148), and higher CCL23 was associated with poorer semantic memory (beta=-0.206). Furthermore, protein\u2009\u00d7\u2009time interaction analyses indicated that higher OPG, Stem cell factor (SCF), and chemokine (C-X-C motif) ligand 9 (CXCL9) levels were associated with faster decline in global cognition (OPG\u2009\u00d7\u2009time term: beta=-0.042), semantic memory (SCF\u2009\u00d7\u2009time term: beta=-0.059, OPG\u2009\u00d7\u2009time term: beta=-0.043), episodic memory (SCF\u2009\u00d7\u2009time term: beta=-0.064; OPG\u2009\u00d7\u2009time term: beta=-0.044), and visuospatial ability (CXCL9\u00d7time term: beta=-0.012). In latent class mixed models, several significant protein\u2009\u00d7\u2009time interactions were observed for episodic memory in the subgroup with initial below-average performance and gradual decline. Using elastic net regression, we identified signatures of global cognitive level (26 proteins), but the prediction of cognitive decline was poor. In older Black adults, circulating inflammatory proteins were linked to cognition, reinforcing the role of systemic inflammation as a potential driver of neurodegeneration in this population.\n\nID: 42466150\nTitle: Targeting the cardio-neuro axis through nutrition: inflammatory mechanisms linking cardiovascular and neurodegenerative diseases.\nAbstract: Non-communicable diseases (NCD), particularly cardiovascular diseases (CVD) and neurodegenerative diseases (ND), remain leading causes of global morbidity and mortality. Although traditionally studied in isolation, accumulating evidence indicates that these conditions are mechanistically interconnected through shared pathways, including chronic systemic inflammation, endothelial dysfunction, and dysregulated lipid metabolism. Here, we propose a cardio-neuro axis in which vascular and neurodegenerative processes are linked along a continuum that is modifiable through diet. In this perspective, we synthesise evidence linking inflammatory and neurovascular dysfunction across CVD and ND and argue that nutrition represents a primary, yet under-integrated, lever for targeting these shared mechanisms. We focus on dietary patterns and bioactive components that influence inflammation resolution, endothelial function, and metabolic homeostasis. However, despite strong mechanistic rationale, nutritional strategies for ND remain fragmented, with an overreliance on single-nutrient interventions and limited incorporation of vascular endpoints or mechanistic biomarkers. We contend that progress in this field requires a shift from reductionist approaches toward whole-diet interventions evaluated using integrated cardio-neuro outcomes, alongside stratified and personalised designs. Embedding nutrition within a unified cardio-neuro framework earlier in life may offer a scalable and mechanistically grounded strategy to reduce the burden of NCD across the life course.\n\nID: 42465490\nTitle: Genetic context alters central nervous system compartment dependent responses to lipopolysaccharide.\nAbstract: Systemic inflammation drives neurodegeneration, yet its differential effects across neural tissues and genetic backgrounds remain poorly understood. We performed RNA-sequencing on brain, optic nerve head (ONH), and retina from four genetically diverse mouse strains (B6, CAST, NZO, WSB) following lipopolysaccharide (LPS)-induced systemic inflammation. The ONH mounted the largest response to LPS (9510 DEGs), followed by retina (5152) and brain (4586). A conserved core of 1444 DEGs across all tissues was enriched for innate immune and acute-phase pathways. Tissue-specific responses were apparent; the retina downregulated phototransduction and visual perception genes; ONH exhibited bidirectional remodeling with upregulated proteasome and ribosome biogenesis and suppressed lipid metabolism and lysosomal function; yet the brain displayed no significant pathway level enrichment. Genetic background strongly modulated the LPS response across the three tissues; the retina exhibited the greatest strain-dependent divergence. Interestingly, differing genetic context affected the ONH response to LPS the least despite its markedly larger response to LPS overall. In totality, both genetic and physical context dictate the neuroinflammatory response to LPS.\n\nID: 42464739\nTitle: Brain iron deposition mediates cognitive impairment in COPD: A possible imaging marker linking systemic inflammation to neurodegeneration.\nAbstract: Cognitive impairment is a relatively prevalent comorbidity in chronic obstructive pulmonary disease (COPD), yet its neuropathological mechanism remains poorly understood. We enrolled 48 stable COPD patients, categorized into cognitively normal (CogN, n = 22) and impaired (Cog, n = 26) groups based on Montreal Cognitive Assessment (MoCA) scores, along with 34 matched healthy controls. All participants underwent 3T MRI with quantitative susceptibility mapping (QSM) to quantify regional brain iron content. Group comparisons of whole-brain and region-of-interest susceptibility were performed. Mediation analysis was then used to test whether specific brain iron deposition mediates the relationship of both COPD status and peripheral inflammatory markers with cognitive performance. Cog patients showed increased total iron in the right cerebellum crus I, while CogN patients exhibited higher paramagnetic susceptibility (\u03c7para) in the left orbitofrontal cortex (OFC), right precentral gyrus, and right brainstem. \u03c7para in the left OFC and right brainstem were positively correlated with total MoCA, abstraction, and orientation scores. Mediation analysis demonstrated that \u03c7para of the left OFC mediated the effects of both COPD status and systemic neutrophil counts on impaired abstraction. Additionally, right brainstem \u03c7para mediated the relationship between COPD and deficits in orientation. COPD patients with cognitive impairment exhibited distinct patterns of brain iron deposition. Importantly, deposition in several key regions served as a potential mediator, linking both COPD and systemic inflammation to specific cognitive deficits. These preliminary findings suggest a possible association between brain iron accumulation and cognitive impairment in COPD, offering candidate neuroimaging markers for early identification.\u2009\u2009.\n\nID: 42448200\nTitle: Oral disease-associated proteins implicated in neuronal disorders: Emerging roles in diagnosis and treatment.\nAbstract: Oral health plays a crucial role in maintaining cognitive functions, reflecting a complex interplay between the oral cavity and brain health. Emerging evidence indicates that various oral disease-associated protein molecules are implicated in the pathogenesis of diverse neuronal disorders, including neurodegenerative diseases. This review comprehensively summarizes oral disease-related protein molecules involved in several neuronal disorders, including Alzheimer's disease, Parkinson's disease, neurodegeneration, neuroinflammation, dementia, cognitive decline, and brain fog in two different contexts. Firstly, it describes protein molecules under the classical oral disease condition [A\u03b242, total-Tau, phosphorylated-Tau, \u03b1-synuclein, DJ-1, lactoferrin, MMP-2/8/9, IL-6, IL-1\u03b2, TNF-\u03b1, CRP, S100A8, S100A9, S100B, RAGE, LCN2, cathepsin B/L, HSP70/90, NfL, CXCL2/8, C3/4, defensins (\u03b1 and \u03b2), and lysozyme]. Secondly, it explains in COVID-19 context [ACE2, TMPRSS2, furin-1, NRP1, spike, T1R, and T2R]. The review explores oral proteins implicated in neuronal disorders, highlighting their roles in activating inflammatory pathways, contributing to memory impairment, and mediating taste dysfunction in the context of COVID-19. Furthermore, the review delineates the mechanisms underlying the oral-brain axis, highlighting the roles of systemic inflammation, microbial interactions, and blood-brain barrier dysfunction in mediating these effects. It also highlights the innovative diagnostic potential of oral disease-associated proteins as non-invasive biomarkers for early detection and monitoring of neuronal disorders in both classical and COVID-19 contexts. In addition, the emerging therapeutic significance of these proteins is discussed, emphasizing their potential as molecular targets for the prevention and treatment of neurological diseases. Understanding oral disease-associated protein molecules provides novel insights into early diagnosis and progression of neuronal disorders.\n\nID: 42416017\nTitle: Mechanisms of multi-organ damage in Wilson disease from the gut-liver-brain axis perspective: copper metabolism, gut microbiota, and metabolite communication.\nAbstract: Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations, leading to pathological copper deposition in the liver, brain, and cornea. Although the gut-liver-brain axis plays a role, direct copper accumulation in multiple organs remains the primary cause of tissue damage. Recent years have seen growing attention to the gut microbiota in WD pathogenesis. Copper imbalance remodels gut microbiota composition and function, while dysbiosis, in turn, affects copper absorption and excretion, forming a vicious cycle that exacerbates multi-organ damage. Copper-induced intestinal barrier disruption, lipopolysaccharide translocation, and systemic inflammation are key links connecting local copper accumulation to systemic injury. This review summarizes the genetic basis of WD, mechanisms of copper toxicity, gut microbiota alterations, and their roles in liver injury and neurodegeneration. It highlights microbiota-derived metabolites-short-chain fatty acids, tryptophan metabolites, bile acids, sulfur-containing amino acids, and branched-chain amino acids-in inter-organ communication. The bidirectional interaction between WD therapies (chelators, zinc salts, dietary interventions) and the gut microbiota is analyzed, along with microbiota-based personalized therapies. However, most current evidence derives from animal models or small cross-sectional studies; large-scale longitudinal human data are critically lacking. A deeper understanding of the gut-liver-brain axis in WD may reveal novel biomarkers and therapeutic targets.\n\nID: 42403869\nTitle: Cardiovascular Biomarkers as a Primary Care Gateway to Early Alzheimer's Disease Detection: The Case for an Integrated Screening Approach.\nAbstract: Alzheimer's disease (AD) affects millions of Americans and represents one of the leading causes of disability and healthcare expenditure in the United States. The vast majority of patients are diagnosed at the symptomatic stage, when substantial neuronal loss has already occurred and the therapeutic window for disease-modifying treatment has closed. Recently approved disease-modifying therapies have created an urgent clinical need for pre-symptomatic patient identification. The cardiovascular risk factors most commonly managed in primary care -- hypertension, dyslipidemia, type 2 diabetes, atrial fibrillation, and chronic heart failure -- are among the most powerful modifiable antecedents of AD pathology, operating through systemic inflammation, cerebral small vessel disease, impaired glymphatic clearance, and tau hyperphosphorylation. The biomarkers used to monitor these conditions -- C-reactive protein, cardiac troponin, NT-proBNP, and homocysteine -- reflect active neurodegeneration risk processes already measured routinely in primary care. This clinical perspective proposes a three-stage\u00a0integrated neuro-cardiological screening protocol linking cardiovascular biomarker assessment to plasma P-tau217 blood testing for AD confirmation. This framework addresses the implementation gap identified in recent United States primary care literature and represents a practical step toward closing the AD diagnostic gap.\n\nID: 42377735\nTitle: The interplay between gut microbiota and Alzheimer's disease: mechanistic insights from dysbiosis to disease modulation.\nAbstract: Alzheimer's disease (AD) is a chronic, progressive, neurodegenerative condition marked by memory loss and cognitive decline. It is characterized by neuropathological features such as amyloid plaque accumulation, neurofibrillary tangles of tau protein, and inflammatory changes in the brain. Recent research emphasizes how gut microbes influence the onset and progression of AD primarily through the gut-brain connection, a bidirectional communication system. The human gastrointestinal tract (GI) contains trillions of bacteria, primarily Bacteroidetes, Firmicutes, and Actinobacteria, which play vital roles in digestion, metabolic regulation, and immune modulation. However, factors such as diet, lifestyle, and environmental exposure can disrupt microbial balance, weaken intestinal barrier function, and initiate systemic inflammation. Such dysbiosis has been linked to defective regulation of the amyloid precursor protein (APP), leading to increased deposition of amyloidogenic peptides (A\u03b2). Moreover, the enteric nervous system, which expresses APP, may serve as an initial site of amyloid deposition, affecting gastrointestinal motility and inflammatory susceptibility. The gut microbiota also produces key bioactive compounds, including neurotransmitters such as serotonin, dopamine, acetylcholine, histamine, and gamma-aminobutyric acid (GABA), which influence the central nervous system (CNS) through neural, immune, and endocrine pathways. An imbalance in these neuroactive molecules may disrupt synaptic signaling and contribute to Alzheimer's-related cognitive dysfunction. Therefore, improving our understanding of gut-brain communication may advance knowledge of AD development and support the creation of new therapies. This review highlights the strong association between intestinal microbes and Alzheimer's pathogenesis, emphasizing microbiota modulation through probiotics, prebiotics, postbiotics, synbiotics, and antibiotics as potential therapeutic approaches, supported by emerging clinical trial evidence.\n\nID: 42371165\nTitle: The microbiota-mitochondria axis: linking metabolic dysfunction to neurodegeneration.\nAbstract: The interplay between gut microbiota and mitochondria represents a dynamic relationship that profoundly impacts host physiology, ranging from maintaining intestinal homeostasis to regulating systemic metabolic and neurological functions. Microbial metabolites such as short-chain-fatty-acids, bile acids, and amino acid derivatives serve as pivotal modulators of mitochondrial bioenergetics, oxidative stress management, and fission-fusion processes. These interactions are vital for preserving epithelial integrity, supporting energy metabolism, shaping immune responses, and managing inflammatory signaling pathways. Disruptions within this microbiota-mitochondria axis are associated with various pathologies, including non-alcoholic fatty liver disease, obesity, type 2 diabetes, and chronic inflammatory conditions like inflammatory bowel disease. Additionally, growing evidence connects gut dysbiosis and mitochondrial dysfunction to neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease, highlighting the importance of this bidirectional relationship in maintaining neuronal health. On a mechanistic level, pathways involving AMPK, sirtuins, and PGC-1\u03b1 govern mitochondrial biogenesis and adaptive responses to microbial signals. Dysregulation of these pathways can heighten oxidative stress, hinder mitophagy, and contribute to systemic inflammation. Emerging therapeutic strategies aim to target this axis through dietary modifications, probiotics and engineered microbes, FMT, and mitochondria-specific pharmacological treatments. These interventions focus on restoring metabolic stability, enhance resilience against oxidative damage, and slowing disease progression. By integrating insights from fields such as metabolism, immunology, and neuroscience, this review positions the microbiota-mitochondria axis as a critical area of focus in biomedical research. A deeper understanding of this communication network offers promising opportunities for precision therapies aimed at addressing metabolic, inflammatory, and neurodegenerative diseases.\n\nID: 42369655\nTitle: Sarcopenia in cognitive disorders: Toward a shared pathophysiological framework.\nAbstract: Sarcopenia and cognitive disorders frequently co-occur and may share convergent biology spanning systemic inflammation, vascular dysfunction, oxidative stress, and hormonal-metabolic dysregulation. Literature search was conducted using PubMed, Cochrane, Embase, and CENTRAL from January 2000 to March 2026. Search terms included \"Sarcopenia\", \"Mild Cognitive Impairment\", and \"Dementia\". Eighty-two studies met inclusion criteria (54 clinical; 28 interventions), discussing epidemiological trends, mechanistic pathways, biomarkers, and therapeutic targets. Clinical evidence clustered across inflammation, vascular change and energetics, hormonal-metabolic dysregulation, and biomarkers. Elevated inflammatory mediators tracked slower gait, weaker grip, and poorer cognition, mapping to mobility decline and Montreal Cognitive Assessment (MoCA) deficits. Cross-domain readouts linked muscle and brain: muscular fat infiltration related to worse cognitive-motor performance; temporalis muscle thickness correlated with MoCA and tau signal; impaired post-exercise phosphocreatine recovery associated with higher neurodegeneration risk and slower processing/gait. Blood biomarkers consistently stratified motor-cognitive status/decline. Among intervention reports, aerobic/resistance training improved strength, mobility, and often processing outcomes; protein (\u00b1 vitamin D) and n-3 polyunsaturated fatty acid showed supportive but heterogeneous effects; vitamin D alone showed mixed muscle results but associated with lower dementia incidence; single-pathway metabolic/anti-cytokine strategies were mixed. Few studies powered dual musculoskeletal-cognitive endpoints, limiting quantitative synthesis. There is compelling evidence for bidirectional crosstalk between sarcopenia and cognitive impairment. However, evidence substantiating shared interventions remains limited and could benefit from more multi-center dual-outcome randomized controlled trials. Establishing consensus risk stratification criteria based on common biomarkers may support integrated management of these conditions, improving patient outcomes.\n\nID: 42367763\nTitle: Gut dysbiosis and systemic inflammation in elderly hypertensive patients with amnestic mild cognitive impairment.\nAbstract: Gut microbial dysbiosis has been linked to both high blood pressure and neurodegeneration, but its involvement in hypertensive patients with amnestic mild cognitive impairment (aMCI) has not been well characterized in this specific population. In this cross-sectional investigation, we enrolled 205 older Chinese adults: 52 healthy controls, 83 hypertensive individuals with normal cognition (HTN-CN), and 70 hypertensive subjects with aMCI (HTN-aMCI). Gut microbiota composition was profiled by 16S rRNA sequencing, and serum levels of 27 inflammatory mediators were quantified by multiplex immunoassay. Compared to the HTN-CN and control groups, the HTN-aMCI group showed not only a greater richness of gut microbes but also a markedly segregated microbial community structure. The HTN-aMCI microbiota was characterized by significant depletion of short-chain fatty acid (SCFA)-producing genera (Roseburia, Blautia, Faecalibacterium) and enrichment of opportunistic pathogens (Streptococcus, Clostridium_sensu_stricto_1, Enterococcus). Co-occurrence network analysis revealed disrupted microbial interactions in HTN-aMCI, and functional prediction showed enhanced lipopolysaccharide biosynthesis and reduced SCFA metabolism. HTN-aMCI patients had elevated pro-inflammatory cytokines (IL-1\u03b2, IL-6, IL-8, IL-17, IP-10, RANTES). Notably, after FDR correction, Blautia abundance correlated negatively with inflammatory markers and positively with cognitive scores, whereas pathobionts showed opposite patterns (all q < 0.05). These findings indicate that hypertensive individuals with aMCI harbor a specific gut microbial dysbiosis marked by loss of SCFA producers, expansion of pathobionts, and disrupted microbial networks, which together associate with systemic inflammation and cognitive decline. Our results support the notion that targeting gut microbiota might represent a potential therapeutic avenue for hypertension-related cognitive impairment.\n\nID: 42346280\nTitle: Gastric Juice miR-106a-5p as a Non-Invasive Biomarker of Neuroinflammation and Neurodegeneration: A Prospective Observational Study.\nAbstract: Neuroinflammation is a key contributor to the progression of several neurodegenerative disorders, including Alzheimer's disease, stroke, and small vessel disease. Emerging evidence highlights the role of circulating microRNAs (miRNAs) as non-invasive biomarkers of neuroinflammation and neuronal injury. miR-106a-5p, a member of the miR-17~92 cluster, is known to regulate inflammation, apoptosis, and vascular function. While typically studied in plasma or cerebrospinal fluid, gastric juice miRNAs represent a novel and underexplored source for biomarker discovery within the gut-brain axis. This exploratory study aimed to investigate the association between gastric juice miR-106a-5p expression and markers of neuroinflammation, including C-reactive protein (CRP), lactate dehydrogenase (LDH), and imaging-based evidence of neurodegeneration. A prospective, observational study was conducted on 38 participants (22 with neurodegenerative pathology and 16 healthy controls). Gastric juice samples were analyzed for miR-106a-5p using RT-qPCR, normalized to U6 snRNA. \u0394Ct values were used to determine relative expression. Statistical analyses included t-tests/Wilcoxon tests, ROC curve analysis, and correlation testing, with significance set at p < 0.05. Patients with neurodegenerative changes exhibited significantly lower gastric miR-106a-5p expression compared to controls (p = 0.044). Elevated CRP and LDH levels were associated with higher \u0394Ct values (indicating lower expression), with p-values of 0.019 and 0.023, respectively. ROC analysis showed moderate diagnostic accuracy (AUC = 0.701) for miR-106a in identifying neurodegenerative status. miR-106a levels also correlated inversely with carotid intima-media thickness and brain MRI abnormalities, also reduced gastric miR-106a-5p expression is associated with systemic inflammation and neuroimaging evidence of neurodegeneration. While causality cannot be inferred, these findings suggest that gastric miR-106a may serve as a promising non-invasive biomarker within the gut-brain axis framework. Further longitudinal and mechanistic studies are warranted to validate its clinical utility and explore its potential role in monitoring neuroinflammatory conditions.\n\nID: 42337797\nTitle: The complement system in Alzheimer's disease: evaluating biomarker potential in a complex neuroimmune context.\nAbstract: Neuroinflammatory processes are increasingly recognised as important modulators of Alzheimer's disease (AD) progression, driving interest in immune-related biomarkers beyond classical pathological measures. Among these, the complement system has attracted attention because of its interactions with amyloid-\u03b2 (A\u03b2) and tau pathology, genetic associations with AD risk, and evidence of activation within affected brain regions. However, these biological observations do not directly translate into straightforward biomarker signals. Complement activity is highly dynamic, spans multiple activation and regulatory states, and may reflect both central and peripheral immune processes. This complexity limits interpretation when complement markers are assessed in isolation, as age, systemic inflammation, vascular comorbidity, and blood-brain barrier integrity can influence measured levels. Current evidence does not support complement-derived biomarkers as stand-alone diagnostic classifiers comparable to established amyloid, tau, and neurodegeneration (AT(N)) measures. Their independent or additive value within multimodal biomarker frameworks remains unclear, partly because of cohort heterogeneity, incomplete assay harmonisation, uncertain tissue-source attribution, and limited longitudinal validation. This review critically evaluates complement-derived measures as biologically informative markers of neuroimmune activity in AD, distinguishing biological plausibility from analytical and clinical utility. We argue that their most defensible current role is within multimodal biomarker frameworks, where they may provide context-specific information on inflammatory state rather than function as independent diagnostic, staging, or treatment-monitoring tools. Progress toward clinical application will require rigorous standardisation, mechanistic clarification, and validation across large, longitudinal, and diverse cohorts.\n\nID: 42334840\nTitle: Unhealthy dietary patterns and Alzheimer's disease: associations and underlying mechanistic pathways.\nAbstract: Unhealthy dietary patterns are increasingly recognized as important modifiable factors associated with cognitive decline and Alzheimer's disease (AD). Diets characterized by high intake of saturated fats, refined sugars, and ultra-processed foods are consistently linked to metabolic dysfunction, systemic inflammation, and impaired brain health. Epidemiological and interventional studies suggest that these dietary patterns are associated with poorer cognitive outcomes, whereas adherence to nutrient-rich dietary patterns such as the Mediterranean, MIND, and DASH diets is linked to improved metabolic profiles and slower cognitive decline. Several biological mechanisms have been proposed to explain these associations, including insulin resistance, oxidative stress, neuroinflammation, vascular dysfunction, and alterations in gut-brain axis signaling; however, much of the current human evidence remains observational, limiting definitive causal inference. Emerging research also indicates that individual susceptibility to diet-related AD risk may be modified by genetic background, metabolic status, and sex-specific biological factors. Despite variability in study findings, the overall body of evidence supports a biologically plausible relationship between dietary quality and key processes implicated in AD pathogenesis. Future research should prioritize long-term, biomarker-driven randomized controlled trials, alongside life-course approaches that consider early- and mid-life dietary exposures, to better clarify causal pathways and inform targeted nutritional strategies for AD risk reduction.\n\nID: 42333360\nTitle: Oral-Systemic Links: A Narrative Review of the Role of Periodontitis in Alzheimer's Disease Development.\nAbstract: Alzheimer's disease (AD) and periodontitis are prevalent chronic conditions that disproportionately affect aging populations and pose substantial public health challenges worldwide. Increasing evidence suggests a potential association between these two diseases, with chronic oral infection and systemic inflammation emerging as key linking mechanisms. Periodontitis is characterized by a dysbiotic oral microbiome and persistent inflammatory responses that can lead to the dissemination of periodontal pathogens and their virulence factors into the systemic circulation. Notably, some studies have reported the detection of pathogens such as Porphyromonas gingivalis and their toxic products in the brains of individuals with AD, implicating a possible role in neuroinflammation and neurodegeneration. However, it should be clarified that detection does not establish causation. This narrative review aims to synthesize the existing evidence from animal studies exploring the link between periodontitis and AD and its related mechanisms, including neuroinflammation, amyloid and tau pathology, blood-brain barrier dysfunction, and systemic interactions. The electronic search in PubMed yielded 585 results. We focused on the past 10 years, thus removing 114 results. A total of 471 studies remained. Of the 471 articles reviewed, 239 studies were excluded based on their titles, abstracts, publication types, and topics because of inappropriate study designs (i.e., designs other than cross-sectional or animal studies). A total of 232 studies were further investigated. In this review, the analysis focused exclusively on animal studies, and the full texts were assessed against predefined eligibility criteria focusing on study design, animal model, periodontal exposure, and AD-related outcomes. Studies that met all inclusion criteria were included, whereas articles with inappropriate study designs or irrelevant outcomes were excluded. After full-text screening, 101 studies remained. Preclinical (animal) evidence supported plausible mechanistic links between periodontitis and AD. Furthermore, oral pathogens appear to mediate this ongoing neuroinflammation.\n\nID: 42311948\nTitle: Consumption of ultra-processed foods is associated with cognitive status in elderly patients.\nAbstract: Emerging evidence suggests that there might be an association between excess consumption of ultra-processed foods (UPFs) on cognitive health. UPF intake could promote systemic inflammation, oxidative stress phenomena, and metabolic dysregulation, contributing to neurodegeneration onset and cognitive decline in elderly population. The aim of this cross-sectional study was to examine the relation between UPF dietary pattern on MCI status in elderly patients taking into account the contribution of inflammatory markers. The dietary intake was assessed using a validated food frequency questionnaire in ninety-two participants. All reported food items were categorized according to the NOVA system, classifying foods on the basis of the extent and purpose of industrial processing. Plasmatic concentrations of TGF-\u03b21 and TNF-\u0251 were measured by ELISA assay at the time of baseline neuropsychological evaluation. The Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) were administered to evaluate the cognitive function in all participants. Non-parametric tests, correlation analysis, and logistic regression models were performed to assess the relations between variables of interest. No significant associations were observed for unprocessed/minimally processed foods, culinary processed foods, or processed foods across the different regression models. In contrast, higher consumption of UPF was associated with increased odds of MCI (adjusted OR\u202f=\u202f4.24, 95% CI: 1.05-17.13). However, after additional adjustment for inflammatory biomarkers (TGF-\u03b2 and TNF-\u03b1), the association was attenuated and no longer statistically significant (OR\u202f=\u202f4.79, 95% CI: 0.73-31.24), although the direction of the association remained positive. UPF consumption may be associated with increased likelihood of MCI, and inflammatory status may potentially play a role in this association.\n\nID: 42307649\nTitle: Gut microbiota and immune modulation: role in neurodegenerative disorders and cancer.\nAbstract: The gut microbiota plays a crucial role in maintaining host metabolic balance and immune homeostasis, with increasing evidence linking its dysregulation to neurodegenerative diseases and cancer. This review aims to provide a comprehensive and integrative analysis of gut microbiota-mediated immune modulation in Parkinson's disease, Alzheimer's disease, and cancer. A structured literature-based approach was employed to examine recent studies focusing on microbial composition, metabolite production, and host microbe immune interactions. We summarize the role of key microbial metabolites, particularly short-chain fatty acids, in regulating immune responses, maintaining gut barrier integrity, and modulating systemic inflammation. In addition, the bidirectional communication along the gut-brain axis is discussed, highlighting its differential involvement in neurodegenerative disorders, while microbiota driven immune mechanisms contributing to tumorigenesis are also evaluated. Importantly, this review emphasizes the translational relevance of microbiome-targeted interventions, including prebiotics, probiotics, synbiotics, and emerging postbiotic strategies, in modulating disease progression and therapeutic outcomes. Although limitations lies in correlating the human gut microbiota to the results obtained from the animal studies which may not fully reflect the physiological conditions of the human gut as it is affected by several factors, this work provides a unified framework linking gut microbiota, immune regulation, and disease pathogenesis, and outlines future directions for the development of targeted and personalized microbiome-based therapies which may be achieved through well designed longitudinal and large scale clinical studies further.\n\nID: 42286650\nTitle: Circadian gatekeepers of the gut-brain-immune axis: implications for neuroinflammation and neurodegeneration.\nAbstract: Circadian rhythms, primarily regulated by light-dark cycles, play a crucial role in maintaining physiological health, including metabolism and immune responses. Evidence shows that circadian rhythms are involved in modulating gut microbiota composition, peripheral and central immune systems, and neurodegenerative disease progression. Recent research has illuminated the complex interplay between circadian rhythms and the gut microbiota-immune-brain axis. This review examines the bidirectional relationship between circadian rhythms and gut microbiota, and explores how this interaction influences brain function through the gut-brain axis, with particular focus on neuroinflammation and neurodegeneration. We aim to provide novel insights that could inform therapeutic strategies to prevent or slow down the progression of neurodegenerative diseases through circadian rhythm modulation.\n\nID: 42278527\nTitle: CRP Is a Key Indicator of Rheumatoid Arthritis-Associated Vascular Injury and Neurodegeneration.\nAbstract: Systemic inflammation plays a pivotal role in the progression of rheumatoid arthritis (RA) and its associated comorbidities, ranging from cardiovascular (CV) disease to neurodegenerative conditions such as Alzheimer's disease (AD). This narrative review examines the molecular cross-talk linking these pathologies, with a specific focus on the distinction between pentameric C-reactive protein (pCRP) and its proinflammatory monomeric form (mCRP). We discuss evidence suggesting that mCRP is not merely a passive marker but also an active driver of endothelial dysfunction, atherosclerosis, and synovial inflammation. This review further explores the connections among inflammatory biomarkers, blood vessel integrity, and neurodegeneration, detailing how persistent cytokine elevation (IL-6, TNF-\u03b1) and vascular injury contribute to cerebral small vessel disease (cSVD) and cognitive decline, with neurofilament light chain (NfL) serving as a key biomarker of neuroaxonal injury. Additionally, we address the neurobiology of pain in RA, highlighting the mechanisms of central sensitization (CS) and neuroimmune signalling that sustain pain-independent joint swelling. This evidence indicates that understanding the dynamic connection between CRP isoforms and neuronal markers should offer new insights for risk stratification and suggests that targeting mCRP may provide a novel therapeutic avenue to mitigate both articular and extra-articular manifestations of RA.\n\nID: 42266250\nTitle: The kynurenine pathway: an immunometabolic bridge linking systemic inflammation to neuroaxonal vulnerability in multiple sclerosis.\nAbstract: Multiple sclerosis (MS) extends beyond focal autoimmune demyelination, with progressive neurodegeneration and cognitive impairment arising from mechanisms not fully explained by inflammatory lesions alone. We propose the kynurenine pathway (KP) as a unifying immunometabolic interface that translates peripheral inflammation into central neuroaxonal vulnerability. Cytokine-driven induction of indoleamine 2,3-dioxygenase accelerates systemic tryptophan catabolism, increasing circulating kynurenine that crosses the blood-brain barrier via L-type amino acid transporter 1 (LAT1). Within the CNS, microglial kynurenine 3-monooxygenase generates the excitotoxic and pro-oxidant metabolites quinolinic acid and 3-hydroxykynurenine, while astrocytic kynurenine aminotransferases produce the neuroprotective antagonist kynurenic acid. This enzymatic dichotomy creates a dynamic amplification loop that intensifies excitotoxicity, oxidative stress, oligodendrocyte injury, and axonal loss. Clinical evidence shows that kynurenine metabolite ratios correlate with plasma neurofilament light chain, cognitive deficits, obesity-related inflammation, and phenotype-specific exercise responsiveness, underscoring KP plasticity as a potential determinant of disease trajectory. By reframing MS through this immunometabolic lens, the KP emerges as both a mechanistic bridge between inflammation and neurodegeneration and a tractable biomarker system with therapeutic potential.\n\nID: 42207784\nTitle: Long-term rapamycin treatment suppresses IL-17-producing gamma delta T cells and blunts neuroinflammation in aging.\nAbstract: Aging is the gradual accumulation of structural and functional changes in an organism over time, including immune remodeling and a progressive increase in basal inflammation, or inflammaging. The mTOR pathway is a central driver of aging-related diseases, such as cancer, chronic inflammation and neurodegeneration; pharmacological inhibition with rapamycin is associated with reduced aged-related morbidity and increased lifespan across species. Nonetheless, concerns remain about the use of rapamycin, a well-established immunosuppressant in transplant medicine, as an anti-aging intervention. Here, we evaluated the impact of prolonged low-dose dietary rapamycin on the aging immune system. Treatment did not significantly alter innate or adaptive immune cell populations, including brain resident microglia; however, it attenuated the age-associated accumulation of IL-17-producing \u03b3\u03b4 T cells, particularly in the peritoneal cavity. After a peripheral inflammatory LPS challenge, circulating IL-17 levels were significantly reduced and correlated with an attenuation of microglia inflammatory phenotype. These findings suggest that prolonged low-dose rapamycin exposure exerts minor systemic immune changes, while selectively limiting age-related \u03b3\u03b4 T cell expansion and neuroinflammation associated with systemic inflammation.\n\nID: 42511164\nTitle: Isolation, Characterization, and Anti-Inflammatory Effects of Carthamus tinctorius L. Leaf-Derived Exosome-like Nanoparticles in ETEC-Challenged IPEC-J2 Cells.\nAbstract: Safflower (Carthamus tinctorius L.) is a cash crop grown worldwide. Its seeds and flowers are primarily processed for edible oil and medicinal raw materials, while stems and leaves are discarded as agricultural waste. Recently, plant-derived exosome-like nanoparticles (PELNs) have gained growing research interest in food nutrition owing to their exceptional biocompatibility and relatively low cost for large-scale production. This study aimed to explore the potential functional value of safflower leaf agricultural waste by isolating safflower-derived PELNs. Firstly, a protocol was established for the isolation and purification of safflower (Carthamus tinctorius L.)-derived exosome-like nanoparticles (Ct-ELNs) from safflower leaves using sucrose density gradient ultracentrifugation. NTA analysis revealed that the 30-45% sucrose fraction enriched with Ct-ELNs exhibited the most uniform particle size, highest particle concentration, and optimal purity. Transmission electron microscopy confirmed typical PELNs ultrastructure: disc- or cup-shaped vesicles surrounded by bilayer lipid membranes. FM4-64 fluorescence suggests time-dependent association and likely cellular uptake of labeled Ct-ELNs by IPEC-J2 cells. Cellular assays demonstrated that Ct-ELNs elevated IPEC-J2 cell metabolic activity under matched protein-normalized dosing conditions. The 30-45% sucrose fraction showed the most favorable physicochemical profile and preliminary in vitro protective effects, including improved IPEC-J2 cell metabolic activity and modulation of Enterotoxigenic Escherichia coli (ETEC)-induced inflammation-related gene expression. Overall, this study established an optimized isolation protocol for Ct-ELNs derived from safflower leaves. These data indicate that safflower-derived Ct-ELNs confer preliminary cytoprotective transcriptional regulatory effects on intestinal epithelial cells under in vitro culture conditions.\n\nID: 42510758\nTitle: Probiotics in Alleviating Constipation: Mechanisms, Strain Screening, and Applications.\nAbstract: Constipation is a prevalent gastrointestinal disorder with limited effective therapeutic options. Probiotics have emerged as promising microecological interventions, yet marked strain-specific efficacy and incomplete mechanistic understanding hinder clinical translation. This review systematically synthesizes evidence from human randomized controlled trials, animal studies, and mechanistic investigations on probiotic interventions for constipation. We catalog major anti-constipation strains across Bifidobacterium, Lactobacillus, Bacillus, and other genera, and summarize key findings from published meta-analyses indicating that B. coagulans improves stool consistency by 52.8%, L. paracasei demonstrates 86.3% effectiveness for incomplete defecation severity and 87.6% for PAC-SYM, while L. reuteri achieves 99.9% effectiveness on PAC-QoL. Mechanistically, probiotics act through four synergistic pathways: gut microbiota modulation, metabolite-mediated actions centered on SCFAs and 5-HT-with strains harboring the abfA gene cluster exhibiting enhanced arabinan utilization for sustained metabolite production-gut-brain axis neuro regulation, and dynamic mucosal barrier restoration. Finally, we propose a systematic four-stage screening pipeline integrating genomic pre-screening, probiotic property evaluation, in vitro functional prediction, and in vivo multi-tiered validation. This review provides a comprehensive framework for evidence-based strain selection and personalized probiotic therapy in constipation management.\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: 42357366\nTitle: Medicinal Plant-Derived Exosome-like Nanoparticles: From Basic Research to Biomedical Applications.\nAbstract: Plant-derived exosome-like nanoparticles (PELNs), a subset of extracellular vesicle (EV) secreted by plant cells, have emerged as revolutionary biomaterial with broad applications in biomedicine, agriculture, and nanotechnology. Structurally, PELNs feature a phospholipid bilayer homologous to plant cell membranes, encapsulating bioactive components such as proteins, nucleic acids, lipids, and secondary metabolites. The native structure of PELNs endows them with enhanced bioavailability, reduced immunogenicity, and improved barrier penetration for precise tissue delivery. Recent studies highlight the cross-kingdom therapeutic potential of PELNs in mammals, including antitumor, anti-inflammatory, tissue repair, immunomodulation and so on. This review comprehensively summarized recent advancements in PELN research, including innovative isolation techniques, molecular characterization, their roles in drug delivery and disease therapy. We also discussed challenges in standardization, scalability, and regulatory frameworks which could provide future perspectives for translating PELNs into clinical and industrial applications.\n\nID: 42281745\nTitle: The Intestinal Barrier: A Multilayered Gatekeeper Against Systemic Disease.\nAbstract: The intestine performs two distinct yet seemingly contradictory functions: the digestion and absorption of nutrients, and the defense against harmful substances and pathogens. The intestinal barrier is a multilayered system maintained by four key components: the physical, chemical, microbiological, and immunological barriers. Each layer plays a unique role in preventing the translocation of harmful entities from the intestinal lumen into the body. Disruption of this integrated barrier increases intestinal permeability, a condition commonly referred to as \"leaky gut,\" in which harmful substances and pathogens can enter the systemic circulation. We also highlight that barrier dysfunction differs between the small and large intestines, reflecting regional differences in epithelial structure, mucus architecture, and microbial load. Growing evidence indicates that such barrier disruption triggers cascades of inflammatory responses in various organs, including the liver, brain, muscles, and kidneys, leading to impaired physiological functions. This review delineates the four layers of the intestinal barrier and explores the systemic consequences of its disruption. In addition, it summarizes current approaches for assessing intestinal barrier function and discusses the strengths and limitations of widely used experimental models. The review also outlines current therapeutic strategies for barrier restoration, including dietary interventions, microbiota-directed approaches, postbiotics, bile acid modulators, anti-inflammatory and immunomodulatory therapies, and lifestyle modification. A deeper understanding of this multilayered gatekeeper is essential for developing novel preventive and therapeutic strategies aimed at restoring barrier integrity and strengthening the defense against a wide range of systemic diseases.\n\nID: 42005347\nTitle: Cargo-driven extracellular vesicles as pharmaceutical nanocarriers: A pharmaceutics-oriented comparison of animal exosomes and plant-derived exosome-like nanoparticles.\nAbstract: Exosomes and plant-derived exosome-like nanoparticles (PELNs) are increasingly investigated as biologically derived nanocarriers that can couple cargo protection with biointerface-enabled transport. From a pharmaceutics standpoint, their therapeutic performance is often cargo-governed (e.g., microRNAs and proteins) and is ultimately constrained by delivery determinants such as stability, biodistribution, cellular uptake, and intracellular trafficking. In this review, we compare animal-derived exosomes (ADEs) and PELNs through a formulation-centric lens, emphasizing how source-dependent molecular composition shapes critical delivery behaviors and translational feasibility. We reorganize representative preclinical evidence into pharmaceutics-relevant delivery scenarios-including systemic/vascular targeting, blood-brain barrier transport, oral gastrointestinal delivery, and tumor microenvironment modulation-to connect cargo identity with exposure-site interactions and pharmacodynamic outcomes. We further discuss engineering strategies for improving payload control, targeting precision, and dosing accuracy, including endogenous enrichment, exogenous loading, and surface functionalization, while highlighting scale-up and safety considerations introduced by modification. Finally, we delineate translational priorities required to advance exosome-based products toward clinical development: standardized dose metrics (particle- and cargo-normalized), quantitative PK/biodistribution-PD relationships, potency assays and critical quality attributes (CQAs), manufacturing consistency under GMP, and regulatory-compliant characterization. Collectively, this review reframes ADEs and PELNs as cargo-driven pharmaceutical delivery systems and provides a practical roadmap for translation, with particular attention to the oral and scalable potential of PELNs.\n\nID: 41972275\nTitle: Enhanced Antiaging Effect of Fermented Ginseng through Biotransformation of Protopanaxadiol (PPD)-Type Ginsenosides to PPD.\nAbstract: Aging couples oxidative stress, inflammation, and leaky gut; ginsenosides are promising yet hobbled by poor conversion. We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis. Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection.\n\nID: 41877549\nTitle: Nanopiezoelectric 3D-Bioprinted Neural Organoid Models Epileptic Neuron-Microglia Circuit in Neurodegeneration.\nAbstract: Epilepsy is increasingly linked to neurodegeneration, yet the cellular drivers of the neuron-microglia interplay remain unclear. Herein, we present \"EpiNeuroid\", a 3D-bioprinted human neural organoid that incorporates barium titanate piezoelectric nanoparticles to generate an on-demand, ultrasound-triggered electrostimulatory microenvironment that induces a hyperexcitable state, recapitulating key electrophysiological signatures indicative of a trend toward epileptiform discharges. EpiNeuroid recapitulates neuronal DAMPs release (HMGB1, TLR4, NF-\u03baB), microglial activation (Iba1, TNF-\u03b1, IL-1\u03b2, IL-6, iNOS), heightened neuronal Ca2+ influx, and progressive viability loss, with microglia amplifying injury and hyperexcitability to establish a self-perpetuating epilepsy-neurodegeneration loop. To enable therapeutic screening, we engineered self-assembled ginsenoside protopanaxadiol nanorods (PPD-NRs), which outperformed free protopanaxadiol by suppressing BDNF/ERK/CREB/mTOR hyperactivation, reducing cytokines and HMGB1, restoring Ca2+ homeostasis, and preserving neurosphere integrity. Collectively, EpiNeuroid provides a human-relevant, tunable platform for the mechanistic dissection and discovery of nanotherapeutic interventions in epilepsy-associated neurodegeneration.\n\nID: 41405182\nTitle: Neuroprotective Effects of Tuina in CP Rats Are Associated With Gut Microbiota Remodeling and Intestinal Barrier Restoration.\nAbstract: Cerebral palsy (CP) is a neurodevelopmental disorder that has been linked to gut microbiota dysbiosis. Although Tuina has shown neuroprotective effects, it remains unclear whether these benefits involve regulation of the gut-brain axis. This study aimed to evaluate the therapeutic effects of Tuina in CP rats, with emphasis on its potential regulation of the gut-brain axis. CP was induced in 7-day-old Sprague-Dawley rats through hypoxia-ischemia. Beginning on postnatal day 8 (P8), the Tuina group received daily Tuina therapy for 32 consecutive days. Motor function was assessed using the negative geotaxis test (P6-P12), the beam balance test (P36-P39), and the modified neurological severity score on P40. Gut microbiota composition was analyzed\u00a0using 16S rRNA sequencing. Brain and intestinal histopathology were evaluated histologically via hematoxylin-eosin and Luxol fast blue staining. Protein expression of BDNF, Nrf2, GPX4, ZO-1, and occludin was assessed via western blotting and immunofluorescence. Serum short-chain fatty acids (SCFAs) were measured by mass spectrometry, whereas oxidative stress and intestinal barrier markers (superoxide dismutase, malondialdehyde, glutathione peroxidase, lipopolysaccharide [LPS], diamine oxidase [DAO], and D-lactate [D-LA]) were detected using enzyme-linked immunosorbent assay. In CP models induced by hypoxic-ischemic encephalopathy, significant brain injury and motor dysfunction were observed, accompanied by gut microbiota dysbiosis and impaired intestinal barrier function. Tuina intervention improved motor function and growth, regulated gut microbiota, and increased serum SCFA levels. It also enhanced intestinal barrier proteins (occludin, ZO-1), reduced serum levels of LPS, DAO, and D-LA, and increased the expression of brain-derived BDNF, Nrf2, and GPX4. Tuina significantly alleviated brain injury and improved motor function in CP rats. These effects were associated with modulation of the gut microbiota and restoration of intestinal barrier integrity, suggesting that the gut-brain axis may mediate the neuroprotective effects of Tuina.\n\nID: 41293219\nTitle: Review on extraction technology and function of plant-derived exosome-like nanoparticles.\nAbstract: Plant-derived exosome-like nanoparticles (PELNs) are currently a hot research topic, which have been confirmed to have similar structures and functions to mammalian-derived exosomes. PELNs are lipid bilayer membrane nanovesicles containing bioactive constituents such as miRNA, mRNA, protein, and lipids obtained from plant cells, that can participate in intercellular communication and mediate transboundary communication, have high bioavailability and low immunogenicity, are relatively safe, and have been shown to play an important role in maintaining cell homeostasis and preventing, and treating a variety of diseases. The author has read recent articles on PELNs and summarized them. We summarized the importance and challenges of PELNs and provided a theoretical basis for the future research and clinical application of PELNs. In this review, we describe the biogenesis, isolation and purification methods, structural composition, stability and function of PELNs, mainly introducing the role of PELN in anti-inflammatory, anti-tumor, and drug delivery.\n\nID: 41103318\nTitle: Bioactive compounds in Chinese herbal medicine: anti-inflammatory mechanisms targeting neurological disorders.\nAbstract: Nearly 16% of the world's population is affected by neurological disorders, including neurodegenerative and neuroimmune diseases caused by acute or chronic inflammation. Inflammatory processes in the central nervous system can exacerbate these diseases by causing neuronal damage and apoptosis. Traditional Chinese medicines have become an important area of research in anti-neuroinflammation and neuroprotection owing to their multi-target effects and favorable safety profiles. In this paper, we review the molecular mechanisms by which bioactive compounds of herbal origin inhibit neuroinflammation and improve disease progression through the modulation of inflammatory factors (including TLR4/MyD88/NF-\u03baB, NLRP3 inflammasomes, and Janus kinase-STAT signaling), epigenetic modifications, cell-type-specific modulation (microglia M1/M2 polarization and astrocyte A1/A2 transformation), and gut-brain axis interactions. These bioactive compounds are mainly classified into those with well-defined chemical structures (such as baicalein, baicalin, berberine, and ginsenoside Rg1), plant extracts (such as tonifying Yang Huiwu Tang, Tongxinluo capsule, Shu Xuning injection, and Xingxiong injection), and preparations based on special mechanisms of action or technical means (such as Hedysari polysaccharides [RHP] and microglial cell exosome carrier berberine and palmatine [Exos-Ber/Pal]). We found that these compounds can improve cognitive and motor dysfunction by inhibiting neuroinflammation while exerting neuronal protection, but their low bioavailability, mechanistic complexity, and lack of clinical translational evidence remain challenges. In the future, a combination of multi-omics techniques, rigorously designed clinical trials, and interdisciplinary strategies will be required to promote the precise application of herbal medicines in neuroinflammation-related diseases.\n\nID: 41075520\nTitle: Xinqingning tablet attenuates ischemic stroke complicated by gut dysbiosis through regulating the miR-126-driven gut-brain axis.\nAbstract: Ischemic stroke (IS), the predominant clinical stroke subtype, is increasingly linked to dysregulation of the gut-brain axis (GBA)-a bidirectional neuroendocrine-immune interface connecting intestinal homeostasis with cerebrovascular pathophysiology. Xinqingning Tablet (XQNT) demonstrates neuroprotective potential in IS complicated by gut dysbiosis (GD), yet its mechanisms of GBA modulation remain unclear. A dual-hit IS-GD mouse model was established via fecal slurry transplantation and permanent middle cerebral artery occlusion (pMCAO) surgery. Gut function was evaluated by constipation indices and histopathological changes, while the neuroprotective efficacy of XQNT (0.36, 0.48, and 0.61 g kg\u207b\u00b9) was assessed via TTC staining, neurological deficit scores, cerebral water content, and Evans blue (EB) extravasation assays. Additionally, Western blot was employed to quantify blood-brain barrier (BBB) and inflammation-associated proteins. microRNA sequencing was used to screen the differentially expressed miRNAs. miR-126 expression levels were measured by RT-qPCR, while concentrations of LPS, IL-6 and IL-10 were determined by ELISA. Finally, mechanistic validation employed intravenous miR-126 agonism/antagonism coupled with phenotypic rescue experiments. XQNT conferred robust survival benefits, while concurrently ameliorating intestinal dysfunction and neurovascular injury. Mechanistically, XQNT elevated miR-126 expression, suppressing NF-\u03baB-driven neuroinflammation. Additionally, miR-126 agonism phenocopied XQNT efficacy, whereas miR-126 inhibition abrogated therapeutic benefits. This study provides early evidence that XQNT functions as a dual-target GBA modulator that alleviates IS with GD via regulation of the miR-126/NF-\u03baB axis. By simultaneously promoting barrier restoration and inflammatory resolution, XQNT offers a promising therapeutic approach that links regulation of the gastrointestinal system with cerebrovascular protection.\n\nID: 41074090\nTitle: Resveratrol alleviates IBD-associated neuropsychiatric comorbidities via microbiota-dependent arginine metabolism reprogramming and microglial M2 polarization through gut-brain axis.\nAbstract: Inflammatory bowel disease (IBD) is intricately linked to neuropsychiatric comorbidities through gut-brain axis dysregulation. This study demonstrates that resveratrol (RSV), a natural polyphenol, alleviates DSS-induced colitis-associated anxiety and depression by reprogramming the microbiota\u2500metabolite-barrier network. RSV (100 mg/kg/day) ameliorated DSS-associated anxiety-like behaviors in open field tests (peripheral zone time \u219312.6%, P< 0.0001) and depression-like phenotypes (TST immobility \u219331.0%, P = 0.0004). It restored colonic barrier integrity via ZO-1 mRNA upregulation (\u219180.4%, P < 0.0001) and PAS score recovery (\u219129.6%, P < 0.0001), while reducing systemic inflammation (serum LPS \u219331.9%, TNF-\u03b1 \u219329.9%; P < 0.0001) vs. DSS. Crucially, RSV attenuated neuroinflammation by enhancing brain ZO-1 protein expression (\u2191146.1%, P = 0.0016), suppressing TLR4/MyD88/NF-\u03baB signaling (TLR4 mRNA \u219368.8%, MyD88 protein \u219348.8%; P < 0.05), and promoting M2 microglial polarization (CD206 protein \u2191171.9%, P = 0.0003) vs. DSS. Multi-omics integration revealed RSV\u2019s dual regulatory mechanism: \u2460 Suppression of the pro-inflammatory Turicibacter4-guanidinobutanoic acid axis (\u219342% and \u219337%, respectively; P < 0.01), disrupting LPS\u2500TLR4\u2500MyD88 cascades; \u2461 Enrichment of barrier-protective Muribaculum (\u2191419%) and Dubosiella (\u2191208%), driving polyamine synthesis (spermidine \u219192%, spermine \u219138%) vs. DSS to reinforce gut-brain barriers. Spearman correlations confirmed Turicibacter-4-guanidinobutanoic acid-LPS-MyD88 interactions(r = 0.658-0.865) and Dubosiella-spermine-ZO-1 associations (r = 0.539-0.725). Conclusions: These findings establish RSV as a microbiota-metabolite modulator that redirects arginine metabolism from a pro-inflammatory bypass to polyamine-mediated barrier repair, offering novel therapeutic strategies for IBD-related neuropsychiatric complications. The integrated \"microbe-metabolite-neuroimmune\" axis provides mechanistic insights into gut-brain crosstalk, emphasizing dual-barrier restoration as a critical intervention node.\n\nID: 41024269\nTitle: Effects of exercise on neuroinflammation in age-related neurodegenerative disorders.\nAbstract: Neuroinflammation plays a critical role in the pathogenesis of aging-related neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, and Multiple Sclerosis. It involves the activation of glial cells and the release of pro-inflammatory mediators and reactive oxygen and nitrogen species, which, when chronically sustained, contribute to neuronal damage and cognitive decline. Recent evidence suggests that regular physical exercise exerts neuroprotective effects by modulating neuroinflammatory pathways and enhancing brain health. Exercise has been shown to regulate the activity of microglia and astrocytes, strengthen the blood-brain barrier, and reduce systemic and gut-derived inflammation-all of which are implicated in the progression of neurodegeneration. Additionally, exercise influences inflammasome signaling, a key component in the innate immune response, further mitigating inflammation-induced neuronal injury. This review summarizes current findings on the impact of physical activity on inflammation and inflammasome pathways in aging-related neurodegenerative diseases, highlighting the therapeutic potential of exercise as a non-pharmacological intervention. Further research is warranted to optimize exercise protocols for maximal neuroprotective benefits.\n\nID: 41009713\nTitle: Exosome-like Nanoparticles Extracted from Plant Cells for Diabetes Therapy.\nAbstract: Diabetes mellitus (DM) is a complex metabolic disorder characterized by chronic hyperglycemia and associated complications such as cardiovascular disease, nephropathy, retinopathy, neuropathy, and chronic non-healing wounds. Current antidiabetic therapies offer only partial glycemic control and are limited by poor bioavailability, adverse effects, and an inability to prevent disease progression. Plant-derived exosome-like nanoparticles (PENPs) have emerged as a promising class of natural nanocarriers with excellent biocompatibility, low immunogenicity, and intrinsic multi-component bioactivity. However, few reviews have addressed recent progress in PENPs for DM therapy. To capture the recent developments in this area, this review provides a systematic synthesis of recent advances in PENPs for DM therapy, covering plant sources, extraction and purification methods, molecular compositions, and therapeutic mechanisms. Preclinical studies have demonstrated that PENPs can improve hyperglycemia, enhance insulin sensitivity, regulate hepatic lipid metabolism, and promote wound healing by modulating oxidative stress, inflammation, gut microbiota, glucose metabolism, and insulin signaling. Additionally, PENPs have been shown to promote angiogenesis via glycolytic reprogramming. Despite these promising findings, challenges including scalable isolation, standardized physicochemical characterization, and clinical translation remain. Future directions include engineering multifunctional PENPs, establishing Good Manufacturing Practice (GMP)-compliant production, and conducting clinical trials to facilitate their integration into precision therapeutics for diabetes management.\n\nID: 40994453\nTitle: Plant-Derived Exosome-Like Nanoparticles: Innovative Nanomedicine for Therapeutic Applications.\nAbstract: Plant-derived exosome-like nanoparticles (PELNs) have demonstrated substantial potential and promising prospects in the realms of disease prevention and therapy. Composed of a diverse array of bioactive constituents and secondary metabolites, they are poised to exert significant influence in anti-inflammatory, antitumor, and antioxidant activities. Furthermore, their inherent nanomaterial properties coupled with excellent biocompatibility render PELNs natural candidates for drug delivery systems, enhancing bioavailability. This paper mainly reviews the biogenesis, isolation, and characterization of PELNs, then endeavors to synthesize the current body of knowledge on them and emphasize their potential therapeutic applications. We focus on key findings regarding anti-inflammatory, antitumor, and antioxidant effects and discuss how these insights can guide the design of next-generation nanomedicines.\n\nID: 40947628\nTitle: Ginsenoside Rk3 Alleviates Neuroinflammation and Gastrointestinal Dysfunction in Parkinson's Disease via Modulation of Gut Microbiota-Mediated Butyric Acid Metabolism.\nAbstract: Accumulating evidence links gut microbiota dysbiosis and metabolic disorders to the pathogenesis of Parkinson's disease (PD). Ginsenoside Rk3 (Rk3), a rare ginseng saponin, possesses anti-inflammatory and microbiota-modulating properties. However, its role in the regulation of the gut-brain axis remains unclear. In this study, the key gut microbial species and microbial metabolites associated with the PD-protective effects of Rk3 was explored using rotenone-induced PD mouse model through behavioral experiments, multiomics analysis and targeted bacteria/metabolites supplementation. Rk3 could restore the intestinal microbial homeostasis by enriching Lactobacillus murinus and Clostridium, and delay PD progression by lightening neuroinflammation in a gut microbiota-dependent manner. Crucially, Rk3 significantly increased levels of microbial metabolite butyrate, which could protect dopaminergic neurons and mitigate neuroinflammation by inhibiting histone deacetylase (HDAC) activity and activating the JAK/STAT3 signaling pathway. Overall, Rk3 delays PD progression via intestinal microbial homeostasis remodeling, highlighting its therapeutic potential for neurodegenerative disorders mediated by the gut-brain axis.\n\nID: 40876612\nTitle: Ginsenoside Rb3 modulates gut microbiota to alleviate cerebral inflammation and ferroptosis via the NLRP3/NF-\u03baB/GPX4 pathway in rats with cerebral ischemia/reperfusion injury.\nAbstract: Cerebral ischemia/reperfusion injury (CIRI) poses a significant threat to human life and health. Ginsenoside Rb3 (Rb3) is known to exhibit protective effects against myocardial ischemia, its impact on CIRI remains unclear. Therefore, we investigated the protective effects of Rb3 on CIRI and its underlying mechanisms. Our results showed that Rb3 reduced cerebral infarct volume, decreased blood-brain barrier (BBB) permeability, and improved neurological deficits in CIRI rats. Rb3 also mitigated cerebral ferroptosis and alleviated neuroinflammation, as evidenced by decreased iron levels, reduced MDA content, an improved GSH/GSSG ratio, and lower levels of TNF-\u03b1, IL-1\u03b2, and IL-6, through modulation of the NLRP3/NF-\u03baB/GPX4 pathway. Additionally, Rb3 alleviated intestinal inflammation, improved the intestinal barrier, and corrected gut microbiota dysbiosis and reduced the microbial metabolites TMAO and LPS in CIRI rats. It is noteworthy that in pseudo germ-free rats with CIRI, fecal microbiota transplants (FMT) from Rb3-treated rats conferred similar protective effects as Rb3. Summarily, this study reveals that Rb3 reduces neuroinflammation and ferroptosis in the brains of middle cerebral artery occlusion/reperfusion (MCAO/R) rats via the NLRP3/NF-\u03baB/GPX4 pathway in a gut microbiota-dependent manner.\n\nID: 40850655\nTitle: Ginsenoside Rg1 mitigates the prolonged isoflurane anesthesia-induced neuroimmune disruptions.\nAbstract: Ginsenoside Rg1, a primary bioactive component of Panax ginseng, has been historically used in traditional Chinese medicine to replenish qi, nourish vitality, and restore cognitive function. Its neuroprotective properties have been documented in conditions involving neurological exhaustion and immune dysregulation. This study investigated the therapeutic potential and mechanisms of ginsenoside Rg1 in mitigating neurobehavioral and systemic immune dysfunction induced by prolonged general anesthesia. Mice exposed to 6\u00a0h of isoflurane anesthesia received ginsenoside Rg1 (10\u00a0mg/kg, i.p.) every 24\u00a0h for three doses. Neurobehavioral outcomes were assessed using Y-maze and open field tests. Hippocampal synaptic function (mIPSCs), systemic inflammation (IL-6, TNF-\u03b1), gut barrier integrity (FITC-dextran assay), and colonic regulatory T cell (Treg) populations were quantified. Treg dependency was validated using DEREG mice with diphtheria toxin-mediated ablation. Mice exposed to prolonged isoflurane anesthesia exhibited anxiety-like behaviors, cognitive deficits, elevated IL-6 and TNF-\u03b1 levels in the hippocampus and bloodstream, impaired synaptic transmission, increased intestinal permeability, and reduced regulatory T cells, indicative of gut-immune-brain axis disruption. Treatment with Ginsenoside Rg1 effectively reversed these deficits by improving behavior, reducing inflammation, restoring synaptic function, and preserving gut-immune integrity. Crucially, Treg ablation in DEREG mice abolished Rg1's benefits, while Treg levels correlated with cognitive improvement. Ginsenoside Rg1 ameliorates anesthesia-induced neuroimmune dysfunction through Treg-mediated gut-immune-brain axis restoration, offering a novel therapeutic strategy for postoperative neurological complications.\n\nID: 40796868\nTitle: Exploring the bioactivity of MicroRNAs Originated\u00a0from\u00a0Plant-derived Exosome-like Nanoparticles (PELNs): current perspectives.\nAbstract: Exosomes, nano-sized extracellular vesicles, facilitate intercellular communication by transferring biomolecules such as microRNAs (miRNAs), which are key regulators of gene expression. While mammalian-derived exosomes (MDEs) have shown therapeutic promise, their clinical application has been limited by challenges such as\u00a0immune-related toxicities, low yield and high production costs. In contrast, plant-derived exosome-like nanoparticles (PELNs) offer a sustainable, biocompatible, and cost-effective alternative, encapsulating a diverse array of bioactive miRNAs with significant therapeutic potential. Studies have demonstrated the ability of PELN-derived miRNAs in cross-kingdom communication, effectively transferring into mammalian cells, where they modulate disease-related pathways, including cancer, inflammation, metabolism, and neurodegeneration. This review explores the bioactivity of plant-derived miRNAs, highlighting their role as novel therapeutic agents. The study explores the bioactivity and potential mechanisms by which these miRNAs influence human cellular processes, focusing on their ability to regulate gene expression in different tissues. Additionally, the study examines recent advances in PELN research, emphasizing their potential for clinical translation in precision medicine, and highlights challenges and future prospects in harnessing the therapeutic capabilities of these bioactive miRNAs. This review underscores the potential of PELNs to revolutionize therapeutic strategies, offering a sustainable, biocompatible, and cost-effective platform for targeted miRNA delivery, paving the way for innovative interventions leveraging nature's own nanocarriers.\n\nID: 40695370\nTitle: Paederia scandens-derived exosome-like nanoparticles as a delivery system for andrographolide to treat ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by relapsing colon inflammation. Side effects and drug resistance limit current therapies. Andrographolide (AG), an NF-\u03baB pathway inhibitor, shows promise in UC treatment but suffers from poor oral bioavailability. In this study, Paederia scandens-derived exosome-like nanoparticles (P-ELNs) were used as a delivery system to enhance the therapeutic efficacy of AG in UC. P-ELNs were extracted from Paederia scandens leaves and characterized for size, zeta potential, and morphology using transmission electron microscopy (TEM) and nanoparticle tracking analysis. AG was loaded into P-ELNs (AG-P-ELNs), and the complex was characterized for encapsulation efficiency using high-performance liquid chromatography (HPLC). The anti-inflammatory effects of AG, P-ELN, and the AG-P-ELNs complex were assessed in LPS-stimulated RAW264.7 macrophages (in vitro) and in a dextran sulphate sodium (DSS)-induced colitis mouse model (in vivo). According to the results, AG-P-ELNs demonstrated a high encapsulation efficiency of 38.64\u00a0% and a stable dispersion system with a zeta potential of -38.55\u00a0mV, indicating good colloidal stability. In vitro, AG-P-ELNs significantly reduced the production of pro-inflammatory cytokines IL-1\u03b2, IL-6, IL-18 and TNF-\u03b1, promoting M1 macrophage polarized to M2. In vivo, AG-P-ELN treatment ameliorated DSS-induced colitis, normalized colon length, and mitigated inflammatory cell infiltration. The AG-P-ELN group showed the lowest NF-\u03baB, NLRP3, and iNOS expression, suggesting a synergistic therapeutic effect in modulating macrophage polarization and inflammation. P-ELNs effectively enhance the bioavailability and therapeutic efficacy of AG in treating UC by improving its solubility, stability, and cellular uptake while modulating macrophage polarization and inflammation. This study provides a novel approach for the delivery of AG and highlights the potential of plant-derived nanoparticles in inflammatory bowel disease management.\n\nID: 40547857\nTitle: Understanding mechanisms of Polygonatum sibiricum-derived exosome-like nanoparticles against breast cancer through an integrated metabolomics and network pharmacology analysis.\nAbstract: Polygonatum sibiricum has a long history of medicinal and edible usages, and has attracted widespread attention from researchers due to its rich pharmacological activities. Research has found that plant-derived exosome-like nanoparticles (PELNs) have enormous potential in the field of biomedicine, such as serving as natural nanomedicines to treat diseases or as carriers for drug delivery. However, there are no studies on P. sibiricum-derived exosome-like nanoparticles (PSELNs) against cancer. This work used ultracentrifugation to extract the PSELNs and characterized them using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and dynamic light scattering (DLS). Proteomics and metabolomics were used to analyze the components of the PSELNs, and the Herb database was used to screen for active metabolites. The OMIM and TTD databases were used to analyze active metabolites, and we further speculated that they may have anti-breast cancer (BC) activity. Network pharmacology was used to analyze the possible mechanisms of the PSELNs against BC, mainly including protein-protein interaction (PPI) network analysis for potential targets, gene ontology (GO) for analyzing biological processes, and Kyoto Encyclopedia of Genes and Genomes (KEGG) for analyzing related signaling pathways. After that, the related data of BC was retrieved from the GEO database, and the clinical expression and survival prognosis of the key genes screened by network pharmacology were analyzed by bioinformatics. Molecular docking and Molecular dynamics (MD) simulation were used to verify the binding of active metabolites in the PSELNs with their targets. Finally, the CCK-8 method was used to validate the inhibitory effect of the PSELNs on BC. Firstly, TEM, NTA, and DLS confirmed that the PSELNs were successfully isolated. Then, Proteomics identified 18 protein components from the PSELNs, including ATP synthase subunit alpha, protein Ycf2, and Mannose/silica acid binding lectin. Metabolomics identified 357 metabolic components from the PSELNs and further screened 23 active metabolites by oral bioavailability (OB), including Sedanolide, Baicalein, and 6-Gingerol, etc. By analyzing 23 active metabolites, it was speculated that the PSELNs may have pharmacological activity against BC. After that, network pharmacology was used to screen 23 key targets of the PSELNs against BC. KEGG and GO enrichment analysis showed that the MAPK signaling pathway, PI3k-Akt signaling pathway, and AMPK signaling pathway were involved in the anti-BC effect of the PSELNs. Through bioinformatics analysis of 23 key targets in BC clinical samples, it was found that, except for ESR1, which was significantly upregulated, CAV1, FGF2, and PPARG were all significantly downregulated. The expression levels of 4 targets were positively correlated with survival status. These 4 targets were validated by molecular docking and MD simulation with active metabolites in the PSELNs, and it was found that the binding of sedanolide and ESR1, Baicalein and PPARG, and 6-Gingerol and ESR1 can remain stable. Finally, The inhibitory effect of the PSELNs on BC cells (MDA-MB-231) was validated by the CCK-8 method. This was the first time that the PSELNs have been studied against cancer. It was verified that they have anti-BC activity, and the mechanism may be related to targets such as ESR1 and PPARG, regulated by active metabolites in the PSELNs. This work laid a foundation and reference for more follow-up related research studies.\n\nID: 40409744\nTitle: Macropinocytosis and Fast Endophilin-Mediated Endocytosis Mediate Absorption of Garlic Chive-Derived Vesicle-like Nanoparticles in Human Intestinal Epithelial Cells.\nAbstract: Dietary extracellular vesicles (EVs) or vesicle-like nanoparticles (VLNs) have been shown to exert beneficial functions in a wide range of diseases such as cancer, colitis, and metabolic diseases. They have also been used as natural carriers for medications. Despite the promising translational potential of dietary EVs or VLNs, the molecular mechanisms of their absorption in the gastrointestinal tract are not well understood. In this study, we investigated the absorption mechanisms of garlic chive-derived VLNs (GC-VLNs) using C57BL/6J mice and a human intestinal epithelial cell line, Caco-2 cells. We found that orally administered GC-VLNs crossed the epithelial layer of the small intestine and entered the underlying lamina propria. GC-VLNs were taken up and transported across the fully differentiated Caco-2 epithelial monolayer. Proteins and lipids, but not RNAs, in GC-VLNs mediated their uptake by Caco-2 cells. Chemical inhibitor treatments demonstrated that macropinocytosis and fast endophilin-mediated endocytosis (FEME) played key roles in the internalization of GC-VLNs. On the other hand, clathrin-coated pit-mediated endocytosis and clathrin-independent carrier/glycosylphosphatidylinositol-anchored protein-enriched early endocytic compartment endocytosis did not contribute to GC-VLN uptake. Activation of macropinocytosis and FEME using their specific activators promoted the internalization of GC-VLNs. In addition, genetic manipulation of key molecules in macropinocytosis and FEME confirmed the important engagement of these two specific endocytic pathways in GC-VLN absorption by human intestinal epithelial cells. Our study has provided proof-of-principle evidence to advance our understanding of the absorption mechanism of GC-VLNs, which would be the key to further manipulation and engineering of these nanoparticles to improve their delivery efficiency as therapeutic modalities or drug carriers.\n\nID: 40390612\nTitle: [Acupuncture effects and neuro-immune regulation: a breakthrough in \"treating diseases at the root\"].\nAbstract: The holistic philosophy of traditional Chinese medicine (TCM) embodied in acupuncture therapy has gained novel insights within the neuroimmune regulatory framework. Its mechanistic framework encompasses 3 pivotal dimensions: 1) Acupuncture stimulation at acupoints transduces mechanical signals into neuroelectrical and biochemical signals, initiating localized immunomodulatory microenvironment remodeling; 2) The autonomic nervous system orchestrates systemic and organ-specific immune homeostasis through vagus nerve-mediated anti-inflammatory effects and sympathetic nerve-mediated bidirectional regulatory dynamics; 3) The enteric nervous system facilitates barrier restoration via neuropeptide-microbiota crosstalk, establishing bidirectional gut-brain axis immune communication. Emerging bioelectronic devices based on somatosensory-autonomic reflex circuits are driving the evolution of acupuncture from empirical practice to precision neuromodulation. Future research should integrate multi-omics profiling and artificial intelligence algorithms to construct a comprehensive \"mechanical stimulation-neural coding-immune response\" mapping paradigm. This will operationalize TCM's core principle of \"treating the root of disease\" into targeted neuromodulation strategies against inflammatory and immune-related disorders through defined neural circuit interventions. \u9488\u523a\u7597\u6cd5\u6240\u5448\u73b0\u7684\u4e2d\u533b\u6574\u4f53\u89c2\u5ff5\u5728\u795e\u7ecf\u514d\u75ab\u8c03\u63a7\u65b9\u5411\u83b7\u5f97\u5168\u65b0\u89e3\u8bfb\u3002\u5176\u4f5c\u7528\u67b6\u6784\u6db5\u76d6\uff1a\u5c40\u90e8\u7269\u7406\u523a\u6fc0\u4fe1\u53f7\u5411\u795e\u7ecf\u7535\u4fe1\u53f7\u548c\u5316\u5b66\u4fe1\u53f7\u8f6c\u5bfc\uff0c\u9a71\u52a8\u7a74\u533a\u5c40\u90e8\u514d\u75ab\u5fae\u73af\u5883\u91cd\u5851\uff1b\u9488\u523a\u8c03\u63a7\u81ea\u4e3b\u795e\u7ecf\u7cfb\u7edf\u7ecf\u7531\u8ff7\u8d70\u4e0e\u4ea4\u611f\u795e\u7ecf\u534f\u8c03\u5168\u8eab\u7cfb\u7edf\u6027\u4e0e\u5c40\u90e8\u9776\u5668\u5b98\u7684\u514d\u75ab\u7a33\u6001\u5e73\u8861\uff1b\u9488\u523a\u8c03\u63a7\u80a0\u795e\u7ecf\u7cfb\u7edf\u901a\u8fc7\u795e\u7ecf\u80bd-\u83cc\u7fa4\u4ea4\u4e92\u4f5c\u7528\u5b8c\u6210\u5c4f\u969c\u4fee\u590d\uff0c\u5efa\u7acb\u80a0-\u8111\u8f74\u514d\u75ab\u901a\u8baf\u7a97\u53e3\u3002\u57fa\u4e8e\u201c\u8eaf\u4f53\u611f\u89c9-\u81ea\u4e3b\u795e\u7ecf\u53cd\u5c04\u201d\u7814\u53d1\u7684\u201c\u7535\u5b50\u836f\u201d\u8bbe\u5907\uff0c\u6b63\u63a8\u52a8\u9488\u523a\u4ece\u7ecf\u9a8c\u64cd\u4f5c\u5411\u7cbe\u51c6\u795e\u7ecf\u8c03\u63a7\u53d1\u5c55\u8dc3\u8fc1\u3002\u672a\u6765\u9700\u6574\u5408\u591a\u7ec4\u5b66\u4e0e\u667a\u80fd\u7b97\u6cd5\uff0c\u6784\u5efa\u201c\u673a\u68b0\u523a\u6fc0-\u795e\u7ecf\u7f16\u7801-\u514d\u75ab\u5e94\u7b54\u201d\u6a21\u5f0f\u56fe\u8c31\uff0c\u5c06\u4e2d\u533b\u201c\u6cbb\u75c5\u6c42\u672c\u201d\u7684\u6838\u5fc3\u7406\u5ff5\u5177\u8c61\u5316\u4e3a\u5e94\u5bf9\u708e\u6027\u53cd\u5e94\u53ca\u514d\u75ab\u76f8\u5173\u75be\u75c5\u7684\u9776\u5411\u6027\u795e\u7ecf\u73af\u8def\u5e72\u9884\u65b9\u6848\u3002.\n\nID: 42544498\nTitle: PPE18 protein of Mycobacterium tuberculosis downregulates LPS-induced IgG production by inhibiting nitric oxide synthesis.\nAbstract: Mycobacterial PPE18 is a virulence factor. Previous studies have demonstrated that recombinant PPE18 protein (rPPE18) downregulates inflammation-induced nitric oxide synthase (iNOS) and nitric oxide (NO) production. Given its ability to inhibit iNOS, we investigated whether rPPE18 can also affect IgG secretion, which is modulated by NO levels. Mouse splenocytes and purified B cells were stimulated with lipopolysaccharide (LPS) to induce iNOS-mediated NO as well as IgG and IgM production. The addition of rPPE18 to LPS-stimulated cells reduced NO and iNOS at both the transcript and protein levels. This was accompanied by a drop in total secreted IgG, which could be reversed by the addition of SNAP, an NO donor. Importantly, rPPE18 did not affect secreted IgM levels. These data suggest that rPPE18 interferes with NO-dependent antibody class-switching from IgM to IgG. This was further confirmed by significantly reduced transcript levels of activation-induced cytidine deaminase (AID) in rPPE18-treated LPS-stimulated splenocytes. AID is crucial for class-switch recombination and is regulated by NO levels. These data highlight a novel mycobacterial virulence mechanism, in which rPPE18 inhibits IgG secretion and dampens protective humoral immunity, which is a critical component of the host anti-mycobacterial response.\n\nID: 42544394\nTitle: Long-term moderate lard intake reduces susceptibility to colitis and secondary liver injury in mice.\nAbstract: The role of dietary fats in inflammatory bowel disease is source-dependent. Lard has long been considered a less favorable dietary fat, yet its effects on intestinal health may be dose-dependent, and the mechanisms remain poorly understood. In this study, a dextran sulfate sodium (DSS)-induced colitis model was used to investigate the effects of moderate intake of different dietary fats-lard, beef tallow (beef), and corn oil (corn)-on colitis and secondary liver injury. We found that, compared to beef or corn, lard reduced susceptibility to DSS-induced colitis, as evidenced by less severe colonic inflammation, enhanced intestinal barrier integrity with upregulation of tight junction proteins (ZO-1, Occludin, Claudin1), and reduced colonic and systemic levels of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, lard-fed mice exhibited less severe secondary liver injury than beef- or corn-fed mice, as indicated by decreased serum ALT/AST levels, lower hepatic LPS accumulation, and reduced oxidative stress markers (MDA, protein carbonyl, 3-nitrotyrosine). Untargeted metabolomics revealed that lard enriched specific intestinal metabolites, including crispolide, steviol, swertiamarin, genipin, and several diglycerides. Hepatic transcriptomics and RT-qPCR validation further showed that lard specifically activated the PPAR signaling pathway and fatty acid degradation pathway, which was corroborated at the protein level by elevated PPAR\u03b1 and PPAR\u03b3 expression. Spearman correlation analysis established positive associations between key intestinal metabolites and critical genes involved in these pathways. These results demonstrated that moderate lard intake reduced susceptibility to DSS-induced colitis and secondary liver injury compared to beef or corn, potentially through modulation of gut-liver crosstalk.\n\nID: 42544276\nTitle: Magnolia biondii-Derived Exosome-Like Nanoparticles Ameliorate Ulcerative Colitis by Suppressing Inflammation, Reducing Oxidative Stress, and Modulating Gut Microbiota.\nAbstract: Ulcerative colitis (UC) is a chronic, relapsing inflammatory bowel disease with limited treatment options and suboptimal remission rates. Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals.\n\nID: 42544182\nTitle: Application and prospects of organoid-on-a-chip in research on the intestinal mucosal barrier.\nAbstract: The integrity of the intestinal mucosal barrier is essential for maintaining normal gut physiology, and its disruption is associated with a wide range of conditions, including trauma- and burn-related intestinal injury, which remain difficult to manage clinically. Intestinal organoid-on-a-chip systems have emerged as advanced in vitro models that reproduce key features of the intestinal microenvironment and physiological function. These systems have shown promise for studying mucosal injury and repair, assessing therapeutic strategies, and supporting translational research. This review summarizes the basic principles of intestinal organoid-on-a-chip technology and examines its use in modeling intestinal barrier function, inflammatory responses, drug screening, regenerative approaches, and trauma-related barrier repair. It also reviews recent progress in preclinical studies, considers potential applications in gastrointestinal research, and discusses current technical challenges, particularly those related to scalability and reproducibility. Future directions for the development of next-generation systems are also outlined. With the continued integration of advances across disciplines, these platforms may provide useful tools for studying and treating disorders involving the intestinal mucosal barrier, especially in the context of trauma and burns.\n\nID: 42544151\nTitle: Comparative Evaluation of Salivary Chemerin and Malondialdehyde Among Patients With Periodontitis and Oral Squamous Cell Carcinoma: A Cross-Sectional Study.\nAbstract: Introduction Periodontitis and oral squamous cell carcinoma (OSCC) are long-lasting inflammatory conditions that lead to tissue damage, oxidative stress, and changes in immune responses. Recent studies indicate a potential biological link between periodontal inflammation and the development of oral cancer. Salivary biomarkers such as chemerin and malondialdehyde (MDA) may serve as non-invasive tools for early diagnosis and disease monitoring. This study was designed to assess and compare salivary chemerin and MDA levels in three groups: healthy individuals, patients with periodontitis, and those with OSCC. Methods This study was conducted on 75 participants distributed evenly among the three groups: healthy individuals (Group A), periodontitis patients (Group B), and OSCC patients (Group C). Clinical periodontal parameters, including Oral Hygiene Index-Simplified (OHI-S), Russell's periodontal index, probing pocket depth (PPD), and clinical attachment level (CAL), were recorded. Unstimulated saliva samples were collected and analyzed for chemerin and MDA levels using enzyme-linked immunosorbent assay (ELISA) kits. Statistical analysis was done using analysis of variance (ANOVA), Tukey's post hoc test, and Pearson's correlation coefficient, with p<0.05 considered statistically significant. Results Salivary chemerin and MDA levels showed a progressive increase from healthy controls to periodontitis patients and OSCC patients. One-way ANOVA revealed statistically significant differences among the three groups for both chemerin (F(2,72)=4.28; p=0.017) and MDA (F(2,72)=3.45; p=0.037). Tukey's post hoc analysis demonstrated significant pairwise differences between all groups for both biomarkers (p<0.001), indicating increasing levels with disease severity. Pearson's correlation analysis showed a statistically significant positive correlation between chemerin and MDA, suggesting an association between inflammatory and oxidative stress pathways in periodontal disease. Conclusion Salivary chemerin and MDA levels were significantly increased in periodontitis and OSCC patients, with the highest levels observed in OSCC. These findings suggest that chemerin and MDA may serve as promising non-invasive salivary biomarkers for the diagnosis, risk assessment, and monitoring of periodontal disease and OSCC. Further large-scale longitudinal studies are recommended to validate their clinical applicability.\n\nID: 42543896\nTitle: Utilization of Postpartum Depression Screening in the Pediatric Emergency Department.\nAbstract: Postpartum depression (PPD) is a common complication of childbirth with significant implications for maternal and child health. Standard screening practices may miss mothers with later-onset symptoms. The pediatric emergency department (PED) may provide an opportunity to extend PPD screening beyond routine outpatient care. To evaluate the feasibility and utilization of Edinburgh Postnatal Depression Scale (EPDS) screening for PPD among mothers of children 12 months or younger presenting to a PED and to describe the demographics of screened patients. We conducted a retrospective descriptive study of EPDS screening implemented as a quality improvement initiative in an urban academic PED between May 15, 2023 and November 30, 2023. Biological mothers of children 12 months or younger were screened at triage using the EPDS in English or Spanish. Positive screens were defined as a score \u22659 or endorsement of suicidal ideation. Demographic data, Emergency Severity Index (ESI), insurance status, EPDS results, and documented interventions were abstracted from the electronic medical record. A total of 734 EPDS screens were completed. Forty-one mothers (5.6%) screened at risk or positive. Of these, 17 (41%) had infants aged 6 to 12 months. Maternal mental health resources were offered to 37 (90.2%) mothers with positive screens. All mothers with positive screens had public insurance. The screened population was predominantly white (41.1%) and Hispanic (41.1%). PPD screening in the PED for mothers of children up to 12 months of age is feasible and may identify at-risk mothers. PED-based screening may help address gaps in maternal mental health care for underserved populations.\n\nID: 42543884\nTitle: Correction to \"Maternal High-Fat Diet and Neonatal LPS Exposure Prolong USV Sequences and Shift Call-Type Repertoires in Neonatal Rats\".\nAbstract: \n\nID: 42543801\nTitle: Gut Microbiome and ADHD: A Narrative Review of Clinical Evidence and Practice Implications.\nAbstract: This narrative review evaluates the current evidence on the efficacy of probiotic interventions for Attention Deficit Hyperactivity Disorder (ADHD) symptoms in both medicated and drug-na\u00efve paediatric and adult populations and assesses the implications for clinical dietetic practice. A narrative review synthesizing randomized controlled trials and observational microbiome studies in paediatric and adult populations, specifically distinguishing between probiotic monotherapy and adjunctive protocols. Observational data confirm gut microbiome alterations in ADHD populations, although specific bacterial signatures vary across studies. Evidence from treatment trials demonstrates that the efficacy of probiotics as monotherapy for core ADHD symptoms remains inconclusive. However, specific adjunctive trials combining probiotics with conventional medication have reported preliminary positive findings on symptom reduction, though results remain heterogeneous. Adult evidence is sparse but indicates potential benefits for emotional dysregulation in specific contexts. This review concludes that current data do not support universal probiotic supplementation or routine clinical recommendation. However, when families inquire about complementary approaches, the existing literature enables evidence informed guidance within a shared decision-making framework that acknowledges the preliminary nature of current findings and sets realistic expectations.\n\nID: 42543530\nTitle: Impact of 3-day turmeric supplementation on fasting and postprandial LPS and chylomicron-related markers in patients with IBS: A randomized crossover trial.\nAbstract: Lipopolysaccharide (LPS) has been implicated in increased gut permeability and low-grade mucosal inflammation, conditions that are linked to the pathophysiology of irritable bowel syndrome (IBS). Because increased dietary fat intake can both trigger IBS symptoms and promote LPS translocation in the gut, this study aimed to better understand how a turmeric formula (TF) affects fasting and postprandial LPS response, after a high-fat challenge in patients with IBS (primary outcome). Secondary outcomes included postprandial ApolipoproteinB48 (Apo-B48) and triglycerides (TG) as markers of chylomicron-mediated LPS translocation, as well as gastrointestinal (GI) symptoms and stool pattern. In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients.\n\nID: 42543510\nTitle: Altered IRF1-miR-20a-5p regulatory axis in the hippocampus of patients with major depressive disorder.\nAbstract: Neuroinflammation has been implicated in the pathogenesis of major depressive disorder (MDD), with interferon regulatory factor 1 (IRF1) playing a potential role. MicroRNAs (miRs) are also involved in MDD through posttranscriptional regulation of gene expression. This study investigated whether miR-20a-5p regulates IRF1 in MDD. IRF1 mRNA and miR-20a-5p expression levels were measured by qPCR in postmortem hippocampi from 14 MDD subjects and 14 controls, and in chronic social defeat stress (CSDS) mice. Their regulatory relationship was examined in HEK293 cells using miR-20a-5p overexpression and a dual-luciferase assay. Neuro2a cells treated with DMSO were used to evaluate the effects of cellular stress on Irf1 and miR-20a-5p expression. IRF1 mRNA and miR-20a-5p expression levels were significantly increased in both MDD hippocampi and CSDS mice. Luciferase assays showed that miR-20a-5p directly targeted the conserved seed sequence within the IRF1 3'-UTR and suppressed IRF1 expression. During the early phase of cellular stress, Irf1 mRNA was upregulated, whereas miR-20a-5p was downregulated, suggesting that stress initially induces Irf1 expression, followed by secondary regulation of miR-20a-5p. IRF1 mRNA expression was increased in the hippocampus of both MDD subjects and CSDS mice. Moreover, miR-20a-5p directly targeted the IRF1 3'-UTR, supporting a potential miR-20a-5p-IRF1 regulatory axis involved in inflammatory signaling in MDD. However, its functional significance in vivo remains to be determined.\n\nID: 42543442\nTitle: Effects of photobiomodulation, alone or combined with dexamethasone, on cellular metabolic activity and inflammatory markers in LPS/IFN-\u03b3-stimulated J774 macrophages.\nAbstract: The aim of the present study was to investigate the effects of photobiomodulation (PBM), dexamethasone (DEXA), and their combination on cellular metabolic activity and inflammatory cytokines in LPS/IFN-\u03b3-stimulated J774 macrophages.Cells were stimulated with lipopolysaccharide (LPS) and interferon-gamma (IFN-\u03b3) and treated with PBM (780 nm) and/or DEXA (2 or 4 \u03bcM). Cellmorphology, metabolic activity assessed by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay, and total protein, tumornecrosis factor-alpha (TNF-\u03b1), and interleukin-6 (IL-6) levels measured by enzyme-linked immunosorbent assay (ELISA) were analyzed at 24 and 48hours. PBM combined with DEXA at 2 \u03bcM increased MTT metabolic activity at 24 hours and was associated with preserved morphology and maintainedhigher total protein levels, with consistent superiority over DEXA alone. PBM + DEXA 2 \u03bcM produced the strongest reduction in TNF-\u03b1 and IL-6 at 24hours, and IL-6 levels remained lower at 48 hours compared to the M1 + PBM group. The 4 \u03bcM dose demonstrated lower efficacy and signs of functionalimpairment, which were partially mitigated by PBM. These findings indicate that PBM may enhance the anti-inflammatory effects of low-dose DEXA while supporting a favorable cellular metabolic response, suggesting its potential as an adjunct strategy to optimize the glucocorticoid-based modulation ofinflammatory responses.\n\nID: 42543374\nTitle: [Mechanism of Xiaoyao San in ameliorating of brain-gut interaction disorder in chronic stress mice based on Th1/Th2 immune balance].\nAbstract: This study investigated the mechanism by which Xiaoyao San ameliorates "brain-gut" interaction disorders in chronic stress-induced mice by examining its effects on T helper 1 cell(Th1)/T helper 2 cell(Th2) immune balance. Forty male C57BL/6 mice(6-8 weeks old, SPF grade) were randomly assigned to four groups(n=10 per group): control group, model group, Xiaoyao San group(7.63 g\u00b7kg~(-1)), and fluoxetine hydrochloride group(4.11 mg\u00b7kg~(-1)). Except for the control group, all groups underwent 28 days of chronic unpredictable mild stress(CUMS) to establish the model. Behavioral tests were conducted on day 28. From day 29, the Xiaoyao San and fluoxetine hydrochloride groups received corresponding drug solutions via oral gavage for 28 days(once daily), while the control and model groups received equivalent volumes of saline. CUMS modeling continued uninterrupted during the administration period. Behavioral assessments were repeated on day 56, with body weight monitored throughout the experiment. Hematoxylin-eosin(HE) staining was used to observe pathological changes in intestinal tissues. The villus height and crypt depth were measured, and their ratio was calculated. Immunohistochemistry(IHC) was employed to detect the expression of tight junction proteins zonula occludens-1(ZO-1) and occludin in the intestinal mucosa. Serum levels of interferon-\u03b3(IFN-\u03b3), interleukin(IL)-2, IL-4, IL-10, corticosterone(CORT), gastrin(GAS), motilin(MTL), and somatostatin(SS) were measured using enzyme-linked immunosorbent assay(ELISA) and subjected to correlation analysis. Western blot was performed to assess T-box transcription factor T-bet and GATA-binding protein 3(GATA-3) protein expression in the hypothalamus and intestinal tissues. The results demonstrated that Xiaoyao San significantly alleviated CUMS-induced depressive-like behaviors, including weight loss, reduced sucrose preference, and decreased locomotor activity in the open field test. HE staining indicated that Xiaoyao San effectively restored intestinal villus structure and increased the villus height-to-crypt depth ratio. IHC results showed that Xiaoyao San enhanced the expression of occludin and ZO-1 related to intestinal mucosal barrier, suggesting improved intestinal barrier function. ELISA analysis revealed that Xiaoyao San significantly decreased serum levels of CORT, SS, IFN-\u03b3, and IL-2, while increasing GAS, MTL, IL-4, and IL-10, indicating mitigation of stress-induced damage and inflammatory responses, as well as regulation of brain-gut peptide secretion. Western blot results showed that Xiaoyao San significantly reduced T-bet protein expression and the T-bet/GATA-3 ratio in both the hypothalamus and intestinal tissues, suggesting correction of Th1/Th2 immune imbalance induced by CUMS. Correlation analysis indicated significant associations between brain-gut peptides and Th1/Th2-related inflammatory factors, implying a link between Th1/Th2 inflammatory responses and brain-gut regulatory function. In conclusion, Xiaoyao San ameliorates brain-gut interaction disorders in chronic stress mice, potentially through restoring Th1/Th2 immune balance, attenuating inflammatory responses, and modulating "brain-gut" peptide secretion.\n\nID: 42543365\nTitle: [Mechanism of ethanol extract of Cyanotis arachnoidea in improving ischemic stroke: a metabolomics and transcriptomics study].\nAbstract: This study aimed to explore the mechanism by which the ethanol extract of Cyanotis arachnoidea(ECA) ameliorates ischemic stroke(IS) in rats, based on metabolomics and transcriptomics. A rat model of middle cerebral artery occlusion(MCAO)-induced IS was established using the modified suture occlusion method. Ninety Sprague-Dawley(SD) rats were randomly divided into the sham operation(sham) group, the model(model) group, ECA low-, medium-and high-dose groups(ECA-L, ECA-M, ECA-H), and the positive drug nimodipine(NMDP) group. The therapeutic effects of ECA were evaluated by neurological deficit scores, 2,3,5-triphenyltetrazolium chloride(TTC) staining, serum biochemical assays, hematoxylin-eosin(HE) staining, and Nissl staining. Transcriptomic and metabolomic analyses were performed on brain tissues from the sham, model, and ECA-H groups. Core gene expression was verified using real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). The results showed that ECA significantly reduced neurological deficit scores and cerebral infarct volume, ameliorated pathological damage in the cerebral cortex, and dose-dependently downregulated the inflammatory factor levels and oxidative stress markers in IS rats. Transcriptomic analysis revealed that ECA-H regulated the expression of 328 differentially expressed genes(DEGs) in the model group, with 129 genes identified as core regulatory targets. Gene Ontology(GO) enrichment analysis showed that these DEGs were mainly involved in IS-related processes, including cerebral cortex development and neuronal development. Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis showed that the DEGs were primarily enriched in pathways such as the calcium signaling pathway and the cyclic adenosine monophosphate(cAMP) signaling pathway. RT-qPCR verification demonstrated that ECA significantly upregulated the relative expression levels of 10 genes related to these two signaling pathways. Metabolomic analysis revealed that ECA-H significantly regulated the levels of 11 differential metabolites in rat brain tissues, mainly involving metabolic pathways such as folate-mediated one-carbon metabolism, lysine degradation, and cysteine and methionine metabolism. In summary, the ECA exerts neuroprotective effects in IS by synergistically activating the calcium and cAMP signaling pathways, targeting the expression of core genes, and regulating key metabolic pathways, thereby inhibiting neuroinflammation, balancing oxidative stress, and alleviating neuronal damage.\n\nID: 42543363\nTitle: [Huangqin Qingre Chubi Capsules alleviate rheumatoid arthritis by inhibiting entry of intestine-derived LPS into bloodstream and blocking M1 macrophage-FLS cell communication].\nAbstract: This study aimed to investigate the therapeutic effect of Huangqin Qingre Chubi Capsules(HQC) on rheumatoid arthritis(RA) and the mechanism of inhibiting RA macrophage polarization by reducing the entry of intestine-derived lipopolysaccharide(LPS) into the bloodstream. ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC. These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication.\n\nID: 42543343\nTitle: [Shenge Yifei Formula ameliorates pulmonary inflammation and dysfunction in chronic obstructive pulmonary disease mice by suppressing Th1 response].\nAbstract: This study aimed to investigate the ameliorative effects of the traditional Chinese herbal compound formula, Shenge Yifei Formula, on pulmonary inflammation and function in mice with chronic obstructive pulmonary disease(COPD) and to elucidate its underlying mechanism from the perspective of inhibiting T helper 1(Th1) immune responses. A COPD model was established in C57BL/6 mice by intratracheal instillation of lipopolysaccharide(LPS) combined with passive smoking exposure. The mice were randomly divided into a blank group, a model group, a tiotropium bromide group, and low-and high-dose Shenge Yifei Formula groups. Following a 5-week intervention, pulmonary function tests and HE staining were performed to assess lung histopathological changes. Flow cytometry, multicolor immunofluorescence, and ELISA were employed to detect the proportion and distribution of CD4~+ C-X-C chemokine receptor 3(CXCR3)~+ Th1 cells in lung tissue, as well as the levels of interferon-\u03b3(IFN-\u03b3), interleukin-12(IL-12), and C-X-C motif chemokine ligand 10(CXCL10) in bronchoalveolar lavage fluid(BALF). Additionally, transcriptomic sequencing was conducted on lung tissue from the high-dose Shenge Yifei Formula group. The study demonstrated that, compared with the model group, Shenge Yifei Formula significantly improved pulmonary function in COPD mice and attenuated alveolar structural damage, airway remodeling, and inflammatory cell infiltration in a dose-dependent manner. Mechanistic investigations revealed that the high dose of Shenge Yifei Formula markedly reduced the proportion and density of CD4~+CXCR3~+Th1 cells in lung tissue and decreased the levels of IFN-\u03b3, IL-12, and CXCL10 in BALF. Transcriptomic analysis further confirmed that its mechanism of action is closely associated with the modulation of immune pathways such as T cell differentiation and cytokine-cytokine receptor interaction. In conclusion, Shenge Yifei Formula effectively ameliorates pulmonary inflammation and dysfunction in COPD mice by inhibiting Th1 cell differentiation, recruitment, and the associated cytokine network. Unlike tiotropium bromide, which primarily improves ventilatory function, Shenge Yifei Formula exerts a significant inhibitory effect on the Th1 axis, suggesting a distinct advantage complementary to bronchodilator therapy at the level of immune inflammation. This study provides modern experimental evidence for the clinical application of Shenge Yifei Formula and indicates its therapeutic potential in COPD by concurrently targeting anti-inflammatory and anti-remodeling processes.\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: 42543294\nTitle: [Overall pathophysiological network of sarcopenia secondary to chronic heart failure from perspectives of modern medicine and TCM].\nAbstract: Sarcopenia is a common and serious complication of chronic heart failure(CHF), with the two conditions forming a vicious cycle. However, the systemic pathological network underlying sarcopenia secondary to CHF remains unclear. This review constructed a multi-level mechanistic framework. Starting from the macroscopic hemodynamic disorders and neuroendocrine activation caused by CHF, the review proceeded to explain how they lead to mesoscopic multi-organ crosstalk dysfunction(including intestinal barrier damage/elevated trimethylamine N-oxide, impaired hepatic synthesis, pulmonary edema, and renal water-sodium retention). These alterations collectively created a systemic milieu characterized by chronic inflammation, oxidative stress, and insulin resistance. This milieu, in turn, triggered a series of microscopic lesions in skeletal muscle, encompassing metabolic imbalance of protein, neuromuscular junction degeneration, microcirculatory disturbances, and myokine secretion dysregulation, all of which ultimately converged, via mitochondrial dysfunction, on a common terminal pathway called "energy metabolism collapse." This review further interpreted this process through the lens of TCM theory, attributing it to a systemic dysfunction rooted in the progression from "Qi deficiency in heart" to "Yang deficiency in heart". This deficiency led to "Yang Qi counterflow" and "three energizer blockage", and the ensuing "internal toxin" and "sthenic fire", corresponding to the states of chronic inflammation and oxidative stress in modern medicine. The multi-level mechanistic framework proposed herein not only elucidates the active role of skeletal muscle via the "muscle-heart axis" but also thereby lays a theoretical foundation for future therapeutic strategies based on multi-target regulation and the integration of TCM and western medicine.\n\nID: 42543288\nTitle: [Transcriptomics study of total flavonoids from Hemerocallis citrina in improving emotional behaviors in chronic stress mice via regulating 5-hydroxytryptamine signaling pathways].\nAbstract: This study aims to investigate the improving effects and potential molecular mechanisms of total flavonoids from Hemerocallis citrina(HCFs) on depression-like behaviors induced by chronic unpredictable mild stress(CUMS) in mice. The mice were randomly divided into a control group, model group, low-dose HCFs group, middle-dose HCFs group, high-dose HCFs group, and fluoxetine group. After four consecutive weeks of gastric gavage administration, the sucrose preference test, forced swimming test, tail suspension test, and open-field test were conducted to evaluate depression-like behaviors. The levels of corticosterone(CORT), interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), hippocampal 5-hydroxytryptamine(5-HT), and brain-derived neurotrophic factor(BDNF) in the serum were determined by enzyme-linked immunosorbent assay; hematoxylin-eosin staining was used to observe hippocampal pathological changes; transcriptome sequencing was performed to analyze differentially expressed genes and Western blot was performed to detect the expression levels of key proteins related to the neuronal function and inflammatory response. The results demonstrate that compared with the model group, HCFs groups with low, medium, and high doses can significantly increase sucrose preference, decrease immobility time, enhance central zone activity, reduce CORT, IL-6, and TNF-\u03b1 levels, elevate BDNF and 5-HT contents, and alleviate hippocampal tissue injury. Transcriptomics and Western blot analyses reveal that HCFs can significantly up-regulate the pathways related to neurotransmitter synthesis, myelin formation, synaptic plasticity, and energy metabolism regulation, while down-regulating the pathways related to inflammatory response and excessive metabolism and regulating the expressions of proteins related to hippocampal neuronal function and inflammatory response. In conclusion, HCFs exert a significant antidepressant effect on CUMS-induced mice, and their mechanism may be related to the multi-target synergistic regulation involving monoamine neurotransmitter balance and neuroinflammation inhibition.\n\nID: 42543286\nTitle: [Inhibition of M1 polarization and inflammatory response in RAW264.7 macrophages by harpagide through PGC-1\u03b1-mediated improvement of mitochondrial function].\nAbstract: This study aimed to investigate whether harpagide can alleviate lipopolysaccharide(LPS) and interferon-gamma(IFN-\u03b3)-induced M1 polarization and inflammatory response in RAW264.7 macrophages by regulating peroxisome proliferator-activated receptor gamma coactivator-1 alpha(PGC-1\u03b1) and improving mitochondrial function. The GEO dataset GSE183077 was used for bioinformatics analysis to identify differentially expressed genes(DEGs) of M1 and M0 macrophages, which was followed by Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses. The M1 macrophage model was established in RAW264.7 macrophages by stimulation with LPS and IFN-\u03b3. Cell counting kit-8(CCK-8) assays were used to evaluate cell viability and determine the optimal concentration of harpagide for treatment. The Griess assay was performed to measure nitric oxide(NO) levels. The mRNA expression levels of interleukin-6(IL-6), interleukin-1\u03b2(IL-1\u03b2), and tumor necrosis factor-\u03b1(TNF-\u03b1) were determined by real-time quantitative polymerase chain reaction(qRT-PCR). JC-1, Mito-Tracker, and Mito-SOX fluorescent probes were used to assess mitochondrial membrane potential, mitochondrial function, and mitochondrial reactive oxygen species(ROS) levels, respectively. Western blot analysis was conducted to detect the protein expression levels of PGC-1\u03b1, NOD-like receptor family pyrin domain containing 3(NLRP3), dynamin-related protein 1(DRP1), inducible nitric oxide synthase(iNOS), and TNF-\u03b1. Transcriptomic analysis revealed that inflammatory responses and mitochondrial fission-related biological processes were significantly activated during M1 macrophage polarization. In vitro experiments confirmed that, compared with the control group, the model group exhibited an increased NO level in cell culture supernatant, elevated mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, impaired mitochondrial function, decreased mitochondrial membrane potential, and elevated mitochondrial ROS levels. Meanwhile, PGC-1\u03b1 protein expression was reduced, whereas NLRP3, DRP1, iNOS, and TNF-\u03b1 protein levels were upregulated. Following harpagide treatment, these changes were reversed in a dose-dependent manner, namely decreased NO production and mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, improved mitochondrial function, restored mitochondrial membrane potential and mitochondrial ROS levels, significantly upregulated PGC-1\u03b1 expression, and decreased expression of NLRP3, DRP1, iNOS, and TNF-\u03b1. In conclusion, harpagide alleviates inflammatory responses probably by modulating mitochondrial fission in macrophages and inhibiting NLRP3 inflammasome activation via activating PGC-1\u03b1.\n\nID: 42543281\nTitle: [Quality markers of Cordyceps militaris in improving respiratory diseases].\nAbstract: This study predicted the quality markers of Cordyceps militaris in improving respiratory diseases by employing high performance liquid chromatography(HPLC) fingerprint, chemometric analysis, and network pharmacology and preliminarily validated them through anti-inflammatory activity evaluation in vitro, providing reference for quality control of C. militaris. HPLC was used to establish fingerprints of fifteen batches of C. militaris, and chemometric analysis was performed to preliminarily screen out differential components. A "component-target-pathway" network was constructed utilizing network pharmacology to further predict quality markers of C. militaris in improvement of respiratory diseases. The inflammatory model of the BEAS-2B cell was induced by lipopolysaccharide, and the levels of inflammatory factors interleukin(IL)-6, IL-1\u03b2, and tumor necrosis factor(TNF)-\u03b1 were detected by quantitative real-time polymerase chain reaction(PCR) to verify the activity of quality markers. Their content was determined by HPLC. In the fingerprints of the fifteen batches of C. militaris, eight common peaks were calibrated, and five main components were identified with similarities between 0.893 and 0.996. Five differential compounds were preliminarily screened through chemometric analysis. Seven efficacy related ingredients were predicted by network pharmacology. Based on the "five principles" characteristics of TCM quality markers, four functional components, namely uridine, guanosine, adenosine, and cordycepin, were ultimately selected as quality markers of C. militaris for improving respiratory diseases. Furthermore, the quality markers were found to significantly inhibit the expression of IL-6, IL-1\u03b2, and TNF-\u03b1, exerting anti-inflammatory effects in in vitro experiments. Their average content was 0.198%, 0.142%, 0.258%, and 0.116%, respectively. This study comprehensively utilized HPLC fingerprint, chemometrics, network pharmacology, and activity evaluation to predict the quality markers of C. militaris in improving respiratory diseases. The study provides references for improving the quality evaluation standard system of C. militaris and lays a foundation for exploring its mechanism in treating respiratory diseases.\n\nID: 42543280\nTitle: [One new ent-kaurane diterpenoid from Isodon serra].\nAbstract: Isodon serra, a Chinese medicinal herb widely used in the Lingnan region, has extensive pharmacological activities. However, its chemical constituents remain to be studied. In this study, a variety of modern chromatographic separation techniques were used to isolate five compounds from 95% ethanol extract of the aboveground part of I. serra. Their planar structures were determined by ultraviolet spectroscopy(UV), infrared spectroscopy(IR), high resolution-electrospray ionization-mass spectrometry(HR-ESI-MS), 1D and 2D nuclear magnetic resonance(1D NMR and 2D NMR), single-crystal X-ray diffraction(SC-XRD), and literature analysis. The compounds were identified as five 6,7-seco-ent-kaurane diterpenoids: isodon I(1), epi-nodosinol(2), carpalasionin(3), epi-nodosin(4), and enmein(5), among which compound 1 was a new one. The results of the pharmacological activity evaluation showed that compound 5 significantly inhibited nitric oxide(NO) release in RAW264.7 cells exposed to lipopolysaccharide(LPS).\n\nID: 42543274\nTitle: [Research progress on active ingredients of Astragali Radix and Acori Tatarinowii Rhizoma and mechanism of their herb pair against Alzheimer's disease].\nAbstract: Alzheimer's disease(AD) is a highly prevalent neurodegenerative disorder with complex pathogenesis. Currently available mainstream drugs offer limited efficacy and often cause significant side effects. The herb pair of Astragali Radix and Acori Tatarinowii Rhizoma, known for its Qi-tonifying and orifice-opening properties in TCM, has demonstrated advantages in multi-target and holistic regulation in anti-AD research. This review systematically summarizes the synergistic mechanisms of active ingredients such as astragaloside \u2163, calycosin, and \u03b2-asarone against AD through multiple pathways, including peroxisome proliferator-activated receptor \u03b3(PPAR\u03b3)/brain-derived neurotrophic factor(BDNF) pathway, phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) pathway, and gut-brain axis. It also points out that current studies remain largely confined to in vitro and animal experiments, with insufficient evidence for clinical translation. Building on this, the review further proposes innovative research directions, such as constructing astragaloside \u2163-\u03b2-asarone co-delivery nanosystems, optimizing the compatibility ratio of the herb pair, and combining with fecal microbiota transplantation to validate causal mechanisms via microbiota-gut-brain axis. These proposals aim to provide a systematic theoretical framework and experimental pathway for the in-depth development and clinical translation of the herb pair of Astragali Radix and Acori Tatarinowii Rhizoma.\n\nID: 42543266\nTitle: [Protective effects of Juhongtai standard decoction against acute lung injury via TLR4/MAPK/NF-\u03baB signaling pathway].\nAbstract: This study aimed to investigate the protective effect and mechanism of Juhongtai standard decoction(JSD) against lipopolysaccharide(LPS)-induced acute lung injury(ALI). In vivo, an ALI model was established using SD rats by intraperitoneal injection of LPS(5 mg\u00b7kg~(-1)). The animals were randomly divided into six groups: control group, model group, dexamethasone(DEX, 0.315 mg\u00b7kg~(-1)) group, and low-, medium-, and high-dose JSD groups(0.787 5, 1.575, and 3.15 g\u00b7kg~(-1), respectively). Wet/dry weight ratio(W/D), myeloperoxidase(MPO) activity, superoxide dismutase(SOD) activity in lung tissues, and nitric oxide(NO) levels in serum were measured. Pathological changes in lung tissue were observed by hematoxylin-eosin(HE) staining, and the percentage of alveolar area(PAA) was scored. Enzyme-linked immunosorbent assay(ELISA) and real-time quantitative polymerase chain reaction(RT-qPCR) were used to detect the content and mRNA expression of tumor necrosis factor(TNF)-\u03b1 and interleukin(IL)-1\u03b2 in serum and lung tissues. Immunohistochemistry and Western blot were employed to analyze the protein expression of Toll-like receptor 4(TLR4) and matrix metalloproteinase 9(MMP9), as well as the phosphorylation levels of inhibitor of nuclear factor-\u03baB(I\u03baB), p65, p38, and extracellular signal-regulated kinase(ERK). In vitro, A549 cells were stimulated with LPS(20 \u03bcg\u00b7mL~(-1)) to establish an inflammation model and treated with JSD-containing serum. Cell viability was assessed by MTT assay. The mRNA expression of TNF-\u03b1, IL-1\u03b2, IL-6, IL-18, TLR4, myeloid differentiation factor 88(MyD88), MMP9, CXC chemokine ligand 2(CXCL2), and IL-10 was detected by RT-qPCR. Western blot was used to evaluate the phosphorylation of I\u03baB, p65, p38, and ERK. The results showed that JSD significantly reduced the lung W/D ratio and alleviated pulmonary edema. It inhibited MPO activity and NO levels and enhanced SOD activity, which indicated the mitigation of oxidative stress. HE staining showed that it significantly ameliorated LPS-induced pathological changes, including alveolar structural destruction and inflammatory cell infiltration, and increased the PAA score. ELISA and RT-qPCR indicated that JSD decreased the levels and mRNA expression of pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2. Immunohistochemistry and Western blot revealed that JSD suppressed the protein expression of TLR4 and MMP9 and downregulated the phosphorylation of I\u03baB, p65, p38 and ERK. In vitro, JSD-containing serum had no significant effect on cell viability but significantly reduced the mRNA expression of inflammatory factors(TNF-\u03b1, IL-1\u03b2, IL-6, IL-18, TLR4, MyD88, MMP9, and CXCL2) and increased the expression of the anti-inflammatory factor(IL-10). It also downregulated the phosphorylation of I\u03baB, p65, p38 and ERK. In conclusion, JSD alleviates LPS-induced ALI by regulating the TLR4/MAPK/NF-\u03baB signaling pathway and thereby suppressing inflammatory response and oxidative stress.\n\nID: 42543264\nTitle: [Saposhnikoviae Radix enhances resistance to respiratory tract infection by potentiating interferon signaling].\nAbstract: This study aimed to investigate the immunopharmacological mechanism of Saposhnikoviae Radix(SR) against respiratory viruses and bacteria infections based on immune signal activation. Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury.\n\nID: 42543263\nTitle: [Effect of Maxing Kugan Decoction on intestinal flora in bleomycin-induced idiopathic pulmonary fibrosis rats].\nAbstract: Based on the "lung-gut axis" theory, this study explored the effects of Maxing Kugan Decoction(Mxd) on inflammation and intestinal barrier and flora in rats with bleomycin-induced idiopathic pulmonary fibrosis(IPF). A total of 24 male SD rats were randomly divided into four groups: a control group, a model group, a positive control group and an Mxd treatment group, with 6 rats in each group. After 5 days of quarantine and adaptive feeding, the IPF pathological model was induced by intratracheal instillation of bleomycin under laryngoscopic assistance in the model group, positive control group, and Mxd treatment group. Gastric gavage was initiated after successful modeling, and all SD rats were sacrificed on the 15th day post gavage. HE staining and Masson staining were used to observe histopathological changes of lung tissue, while HE staining was adopted to evaluate jejunal pathological changes. Enzyme-linked immunosorbent assay(ELISA) was performed to detect the serum levels of interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6), and tumor necrosis factor-\u03b1(TNF-\u03b1) in rats. AB-PAS staining was employed to determine the number of goblet cells in jejunal mucosal tissue. Immunofluorescence assay was used to detect the expression of zonula occludens-1(ZO-1) and occludin in rat jejunum, and 16S rDNA sequencing was conducted to analyze the intestinal microbiome of all rats. The results showed that the model group exhibited severe damage to jejunal mucosa and lung tissue accompanied by massive inflammatory cell infiltration, while the two treatment groups demonstrated partial structural defects with a small amount of inflammatory cell infiltration in the lungs and jejuna of rats. Compared with the control group, the model group showed significantly decreased body weight, number of goblet cells, and expression of ZO-1 and occludin proteins(P<0.01), while these indicators were notably increased after intervention in the two treatment groups(P<0.05 or P<0.01). According to 16S rDNA sequencing results, Mxd could regulate the richness and diversity of intestinal flora in rats. KEGG pathway analysis indicated that Mxd regulated pathways such as oxidative phosphorylation, amino sugar, and nucleotide sugar metabolism of intestinal flora in rats. In conclusion, the alteration of intestinal microbiome may be one of the potential mechanisms underlying the therapeutic effect of Mxd on IPF. Mxd can regulate the structure of intestinal microbiome, increase the abundance of beneficial bacteria, and reduce the number of harmful bacteria, as well as protect intestinal barrier and inhibit inflammatory response.\n\nID: 42538615\nTitle: Pulp Callus Extract From Malus domestica var. Mela Rosa Marchigiana Preserves Intestinal Barrier Integrity and Confers Neuroprotection in a Gut-Brain Axis Co-Culture Model.\nAbstract: The gut-brain axis is a key target in neuroinflammatory disorders. We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference. These findings suggest MRME as a promising nutraceutical candidate for gut-brain axis dysregulation.\n\nID: 42533809\nTitle: The hepatic portal area in homeostasis and disease.\nAbstract: \n\nID: 42529103\nTitle: Non-thermal venous endothelial injury by microsecond irreversible electroporation: mechanisms of apoptosis, oxidative stress, and vascular closure initiation.\nAbstract: Minimally invasive treatments for lower extremity varicose veins carry risks of thermal diffusion injury, nerve damage, ectopic embolism, and limited efficacy, highlighting the need for safer venous closure techniques. Microsecond irreversible electroporation (IRE) is a non-thermal ablation method whose mechanism of action on venous endothelium remains unclear. Using human umbilical vein endothelial cells (HUVECs) and a porcine hepatic portal vein model, we evaluated the killing efficacy, mechanism of action, and in vivo pathological changes induced by microsecond IRE at varying parameters. IRE killed venous endothelial cells in a parameter-dependent manner: apoptosis predominated at 400 V/cm, while necrosis predominated at 800 V/cm with high pulse counts. IRE activated the intrinsic apoptotic pathway via reduced mitochondrial membrane potential, elevated ROS, and calcium overload, while promoting release of DAMPs (ATP, HMGB1, vWF). In the porcine portal vein model, IRE induced early inflammatory and microthrombotic changes while preserving overall vascular wall architecture. Microsecond IRE achieves controllable, non-thermal venous endothelial injury and initiates signals necessary for venous closure, providing preclinical evidence for its development as a novel endovascular treatment for varicose veins.\n\nID: 42514986\nTitle: A Comprehensive Review of the Gut-Microbiota-Brain Axis in Alzheimer's Disease: From Pathophysiology to Potential Therapies.\nAbstract: The gut-microbiota-brain axis (GMBA), an intricate network connecting the gastrointestinal (GI) tract and the brain, plays a pivotal role in maintaining overall health and influencing disease processes. The human gut microbiota, comprising over 3000 bacterial species, regulates immune responses, hormonal signals, and metabolite production, maintaining homeostasis under normal conditions. Dysbiosis, or microbial imbalance, has been linked to various central nervous system (CNS) disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and autism spectrum disorder (ASD). Given the growing interest in this topic and the limited effectiveness of current therapeutic strategies for managing patients with AD, the purpose of the current narrative review is to analyze the pathophysiological role of the GMBA in the pathogenesis of AD and assess potential therapeutic strategies targeting the GMBA, particularly the microbiome and its metabolites. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science to identify clinical studies, experimental research, and review articles examining the GMBA in health and AD, as well as related therapeutic strategies. The search terms included \"Alzheimer's disease\", \"neuroinflammation\", \"amyloid-beta\", \"tau\", \"gut-brain axis\", \"microbiome\", \"short-chain fatty acids\", \"probiotics\", \"prebiotics\", and \"fecal microbiota transplantation\". In AD, altered gut microbiota composition is associated with neuroinflammation, neurodegeneration, and exacerbation of disease progression. Probiotics have shown potential in enhancing cognitive function and reducing neuroinflammation by modulating microbiota composition and influencing brain-derived neurotrophic factor (BDNF) levels. Prebiotics, through their impact on gut microbiota and metabolite production, also offer therapeutic promise by improving cognitive function and mitigating neuroinflammation. With its historical and modern applications, fecal microbiota transplantation (FMT) may represent a potential strategy for addressing dysbiosis and its neurological implications. This manuscript focuses on GMBA and its effects on neuroinflammation, neurodegeneration, and CNS health while emphasizing the need for further research into microbiome-based therapies and the gut-brain relationship in patients with AD.\n\nID: 42512767\nTitle: Rethinking Congestion in Heart Failure from Volume Overload to Venous Pressure and Organ Disfunction with VExUS.\nAbstract: Congestion is a major driver of symptoms, hospitalization, and adverse outcomes in heart failure (HF), yet its clinical assessment remains challenging. Traditional approaches based on physical examination, biomarkers, and isolated imaging surrogates often fail to capture the complexity of systemic venous congestion and its impact on organ function. In HF, congestion should be interpreted as a multifactorial process resulting from the interaction between intravascular volume burden, venous compliance, cardiac filling pressures, neurohormonal activation, blood volume redistribution, and organ-specific susceptibility. In this context, point-of-care ultrasound has emerged as a promising adjunctive tool for bedside congestion assessment. The Venous Excess Ultrasound (VExUS) score integrates inferior vena cava assessment with Doppler analysis of hepatic, portal, and intrarenal veins, allowing for the evaluation of venous pressure transmission and organ-level congestion. Observational studies suggest that VExUS and related venous Doppler abnormalities correlate with invasive hemodynamic parameters and are associated with acute kidney injury, diuretic response, heart failure hospitalization, and mortality. Serial changes in venous congestion may provide additional information regarding treatment response and clinical trajectory. However, the available evidence remains heterogeneous across acute HF, ambulatory HF, cardiorenal syndrome, and critical care populations, and randomized trials evaluating VExUS-guided management are lacking. Therefore, VExUS should be interpreted as a complementary tool within a multimodal assessment that includes echocardiography, lung ultrasound, biomarkers, renal function, urine output, physical examination, and response to therapy. By integrating fluid burden with venous pressure transmission and organ perfusion, multimodal ultrasound may support more individualized congestion assessment and risk stratification in HF.\n\nID: 42512539\nTitle: Cognitive Impairment Associated with Chemotherapy: Neuroimmunological Interactions, Gut-Brain Axis, and Therapeutic Approaches.\nAbstract: Chemotherapy is a treatment designed to contain or eradicate neoplastic cells; however, patients may experience various treatment-related adverse effects. Chemotherapy-related cognitive impairment (CRCI), clinically referred to as \"chemobrain,\" is a frequent complication with a duration ranging from months to years, affecting between 17% and 70% of cancer patients. These cognitive deficits not only impair social, educational, and occupational functioning but may also impact survival outcomes, possibly by interfering with medication adherence and health-related behaviors. Emerging evidence has converged on an integrative cascade in which chemotherapy-induced systemic inflammation, intestinal dysbiosis, blood-brain barrier disruption, microglial/astroglial activation, and impaired hippocampal neurogenesis act in sequence rather than as independent pathways. Underlying pathophysiological mechanisms include neuroinflammation, reduced neurogenesis, loss of dendritic spines, oxidative stress, hormonal changes, epigenetic modifications, and mitochondrial dysfunction. In contrast, repair mechanisms involve complex glial responses, particularly those of astrocytes and microglia. Emerging studies suggest a link between changes in the microbiome and cognitive decline, demonstrating the importance of bidirectional communication in the gut-brain axis. Current research seeks to determine appropriate tests to identify chemobrain. Therefore, several biomarkers, such as GFAP, S100\u03b2, and isoprostanes, have been proposed to assess chemobrain, alongside screening tools such as MoCA, MMSE, and CAB-CF, to evaluate cognitive impairment and enable early detection. Pharmacological candidates-including lithium, fluoxetine, methylphenidate, modafinil, metformin, agomelatine, and melatonin-as well as nutritional and lifestyle interventions such as physical exercise, omega-3 fatty acids, curcumin, probiotics, and traditional Chinese medicine formulations-have been investigated, predominantly in animal models. These remain candidate, not validated, therapies; clinical evidence in CRCI populations is limited, heterogeneous, or absent, and well-powered randomized controlled trials are required before any recommendation can be issued. However, optimal strategies for symptom improvement remain unclear, as various approaches have yielded mixed outcomes. This review provides a comprehensive overview of chemobrain, focusing on its molecular mechanisms, interactions with the gut-brain axis, and potential therapeutic targets to improve the quality of life for cancer survivors.\n\nID: 42512456\nTitle: Integrated Inflammatory and Gut Microbial Signatures in Major Depressive Disorder: A Case-Control Study.\nAbstract: Major depressive disorder (MDD) is increasingly recognized as involving inflammation and the microbiota-gut-brain axis. Few studies have simultaneously assessed systemic inflammatory markers and gut microbiota composition within the same cohort while accounting for metabolic confounders. Moreover, data from Middle Eastern and North African (MENA) populations remain limited, restricting our understanding of how diet may influence neuroimmune-microbiome interactions in depression. This study aimed to investigate associations between MDD, systemic inflammatory markers, and gut microbiota composition in Lebanese adults. To our knowledge, this is the first study of its kind in Lebanon, as well as in the MENA region. In this cross-sectional case-control study, we examined circulating inflammatory markers and gut microbial profiles in 46 adults with DSM-5-confirmed MDD and 25 healthy controls. Plasma C-reactive protein (CRP) and interleukin-6 (IL-6) were measured, and the gut microbiota composition was characterized using 16S rRNA gene sequencing. Multivariable models were adjusted for age, sex, body mass index (BMI), Mediterranean diet adherence, and fluoxetine exposure. Depression status was not independently associated with CRP or IL-6 after adjustment, whereas BMI emerged as a significant determinant of systemic inflammation. At the genus level, MDD was associated with the enrichment of Dorea, Lachnoclostridium, Collinsella, Bilophila, and Klebsiella and the depletion of Christensenella, Mitsuokella, and Victivallis, independent of inflammatory biomarkers. Alpha diversity did not differ between groups, while beta diversity showed modest metric-dependent differences, primarily driven by presence/absence-based measures. Specific microbial taxa may contribute to gut-brain signaling pathways implicated in MDD and systemic inflammation. Further longitudinal and mechanistic studies are required to clarify causal interactions within inflammation-microbiome networks in MDD.\n\nID: 42511198\nTitle: Camel Milk Alleviates Chronic Fatigue Syndrome-like Symptoms in Mice by Modulating the Small Intestinal Microbiota and Inflammation.\nAbstract: This study aimed to investigate the therapeutic effects of camel milk (CM) on chronic fatigue syndrome (CFS) and elucidate the mechanisms underlying the microbiota-gut-brain axis. Using a murine model of CFS induced by chronic restraint and forced swimming stress, we administered lyophilized CM (1500 mg/kg/day, equivalent to approximately 121.5 mg/kg/day in humans based on body surface area conversion using the standard allometric scaling formula) orally. CM supplementation was significantly associated with ameliorated fatigue-like behaviors, as evidenced by prolonged swimming endurance and reduced immobility time. Metagenomic analysis revealed that CM was associated with reshaping of the small intestinal microbiota, including enrichment of beneficial Lactococcus lactis and suppression of pathobionts (H. hepaticus and H. typhlonius). These microbial shifts correlated with increased luminal lactic acid, improved intestinal barrier integrity (increased villus height, reduced crypt depth), and attenuated local inflammation (reduced TNF-\u03b1 and IL-6, elevated IL-10). Consequently, CM was associated with reduced bacterial translocation and systemic inflammation, and normalization of hypothalamic-pituitary-adrenal (HPA) axis hyperactivity. We conclude that CM is associated with prevention of CFS-like symptoms through modulation of the gut ecosystem and strengthening of the intestinal barrier, potentially breaking the vicious cycle of gut inflammation and HPA axis dysfunction, although causality remains to be established through fecal microbiota transplantation or similar mechanistic studies.\n\nID: 42510550\nTitle: Is Ergothioneine an Important Source of Plasma Trimethylamine N-Oxide in Humans?\nAbstract: High circulating levels of trimethylamine-N-oxide (TMAO), largely produced by hepatic oxidation of gut-microbiota-derived trimethylamine (TMA), are associated with increased risk of cardiometabolic and neurodegenerative diseases. In contrast, the diet-derived compound ergothioneine (ET) possesses cytoprotective and neuroprotective properties, and higher circulating ET levels have been linked to a lower risk of cardiovascular, neurodegenerative, and other age-related disorders. However, concerns have been raised that microbial degradation of ET may also contribute to the TMAO pool. In this study, we examined the relationship between ET and TMAO. Bioinformatic analyses indicated that ergothionase, the enzyme responsible for ET degradation to trimethylamine (TMA), is restricted to a limited number of bacterial genera and is far less prevalent than choline trimethylamine lyase, which generates TMA from choline. In a randomised, placebo-controlled human study, ET supplementation (25 mg/day for 7 days) significantly increased plasma ET levels but did not increase TMAO concentrations. Similarly, in a heart failure cohort, plasma ET showed no correlation with TMA or TMAO levels, whereas TMAO was clearly correlated with TMA. Collectively, these findings suggest that ET is unlikely to contribute significantly to systemic TMAO levels.\n\nID: 42508392\nTitle: Targeting the Microbiota-Butyrate-BHB Axis As a Potential Metabolic Therapeutic Strategy for Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is increasingly linked to metabolic and microbial dysregulations, with butyrate and \u03b2-hydroxybutyrate (BHB) identified as key modulators. BHB is a ketone body primarily produced by the liver during periods of low glucose availability, and BHB levels are reduced in the AD brain and peripheral blood. Butyrate, a microbiota-derived short-chain fatty acid, is also reduced in the peripheral blood in association with gut microbiota dysbiosis. The reduction of butyrate and BHB, together with gut microbiota dysbiosis, is commonly observed in AD patients and correlates with cognitive decline and AD-related pathologies. Reduced levels of butyrate and BHB may impair energy metabolism, exacerbating amyloid-beta (A\u03b2) and tau pathologies. In contrast, preliminary evidence from interventional and ketogenic studies suggests that increasing butyrate and BHB levels may attenuate AD-related pathologies, such as A\u03b2 and tau abnormalities, while improving cognitive function. Emerging evidence suggests that both butyrate and BHB can cross the blood-brain barrier (BBB), suppressing oxidative stress and pro-inflammatory cytokines and potentially mitigating A\u03b2 aggregation and tau hyperphosphorylation. Accordingly, therapeutic strategies targeting the microbiota-butyrate-BHB axis represent a promising and biologically plausible approach that warrants further rigorous clinical investigation for the prevention and treatment of AD. This review comprehensively examines the roles of butyrate and BHB in ameliorating key AD-related pathologies, including A\u03b2 aggregation, tau hyperphosphorylation, neuroinflammation, and neurodegeneration. Additionally, the review explores the bidirectional association between butyrate/BHB and gut dysbiosis in AD, including how dysbiosis reduces butyrate/BHB levels while elevating them may reverse dysbiosis and improve gut-brain axis function. Collectively, these findings suggest that butyrate and BHB emerge as promising candidates for potential novel adjunctive therapies for AD, although supporting human evidence remains preliminary and heterogeneous.\n\nID: 42506336\nTitle: The Gut Microbiota in Addiction Biology: A Systematic Review of Substance-Induced Dysbiosis and Gut-Brain Axis Alterations.\nAbstract: Growing evidence suggests that chronic substance use disrupts the gut microbiota composition and function, which can contribute to intestinal dysfunction, systemic inflammation, and gut-brain axis dysregulation. However, current evidence remains fragmented and heterogenous, with most studies focusing on individual substances rather than substance-specific microbial signatures. Therefore, this systematic review synthesizes recent evidence (2019-2025) to characterize the impact of chronic substance use, including alcohol, nicotine, opioids, cocaine, and methamphetamine, on the gut microbiota composition and functional integrity. Following the PRISMA 2020 guidelines, a total of 91,421 records were identified before screening through searches conducted across electronic databases and publisher platforms, including PubMed, Web of Science, ProQuest, and BSCOhost, among others. After duplication removal and application of the predefined eligibility criteria, 60 studies were selected for qualitative analysis. The findings revealed an interspecies similarity in which chronic substance exposure generally induced dysbiosis characterized by a depletion of beneficial short-chain fatty acid (SCFA)-producing taxa, such as Lactobacillus, Akkermansia, and Faecalibacterium, alongside the enrichment of opportunistic pathogens such as Escherichia-Shigella. Alcohol emerged as a particularly potent ecological driver, consistently reducing the richness and diversity of the microbial community. Mechanistically, these alterations are linked to impaired intestinal barrier function, increased lipopolysaccharide translocation, and the activation of systemic inflammatory pathways. Furthermore, substance-specific metabolic fingerprints were identified, including disruptions in glutamate pathways for cocaine and trimethylamine N-oxide precursors for methamphetamine. Preclinical evidence from fecal microbiota transplantation and germ-free models suggests that these microbial shifts actively modulate reward sensitivity and neuroplasticity through the gut-brain axis. Collectively, the data presented in this study support a shift from reductionist addiction models toward a systems-level framework, positioning the gut microbiome as a pivotal, modifiable component of addiction biology and a promising target for novel therapeutic interventions.\n\nID: 42505588\nTitle: The Microbiota as a Potential Cause of Disease.\nAbstract: Background: The human microbiota plays a crucial role in maintaining physiological homeostasis and influencing the development of chronic diseases not only in the gut but in the whole body. Material and Methods: This literature review is based on a comprehensive search of the PubMed database covering the period from 2008 to 2026. Approximately 65 key studies were included in the final analysis. Only articles published in English were included. The search included keywords such as microbiota, inflammaging, eubiosis, diet, gut diseases, cardiovascular diseases, diabetes, and osteoporosis. This narrative review explores the composition, development, and functional significance of the gut microbiota across the human lifespan, highlighting its dynamic interaction with environmental factors. Early-life microbial colonization, shaped by factors including delivery mode and breastfeeding, has long-term implications for immune system maturation and disease susceptibility. Results: A balanced gut microbiota (eubiosis) supports host health through metabolic activities, mainly by the production of short-chain fatty acids (SCFAs), which regulate intestinal barrier integrity, immune responses, and systemic inflammation. Contrarily, dysbiosis-characterized by reduced microbial diversity and an overrepresentation of pro-inflammatory species-is associated with chronic low-grade inflammation (inflammaging) and contributes to the pathogenesis of multiple diseases. Age-related changes in microbial composition are shown to activate inflammatory processes and impair immune regulation, thereby increasing disease risk. Therefore, it is important to recognize the role of microbiota alterations in key pathological conditions, including neurodegenerative diseases, cardiovascular diseases, type 2 diabetes mellitus, and osteoporosis. Conclusions: Finally, the potential of microbiome-targeted interventions, such as probiotics, prebiotics, and dietary modulation-in particular the Mediterranean diet is recognized as the most balanced-is discussed as a promising strategy to restore microbial balance and mitigate inflammaging. Further research is needed to better understand the association between microbiota and host health and to optimize therapeutic approaches for aging populations.\n\nID: 42505345\nTitle: Membrane Fusion-Based Mirabilis Himalaica-Derived Exosome-like Nanoparticles Fused with Cell-Penetrating Peptide Mediated for Chebulinic Acid Delivery Against UVA-Induced Photoaging.\nAbstract: Exposure to ultraviolet (UV), particularly UVA radiation, is a primary driver of photoaging due to its deep dermal penetration, which triggers DNA damage, collagen degradation, and immune suppression. Chebulinic acid (CA), a polyphenolic compound from Terminalia chebula, exhibits potent antioxidant and anti-inflammatory properties against UVB-induced skin damage. However, its large molecular weight hinders transdermal delivery and the TAT47-57 peptide (core of HIV-1 TAT) enables rapid transmembrane transport. Large particles with double-layer membrane structure and a diameter exceeding 1000 nm were obtained during the separation of plant-derived exosome-like nanoparticles (PELNs), which are not considered as PELNs (50-500 nm), after a mixture with TAT anchored to the surface of engineered artificial vesicles (EAVs) and extrusion causes membrane fusion, employed as novel nanocarriers to overcome the difficulty in skin penetration by leveraging their lipid bilayer structure and surface membrane-anchored TAT for efficient epidermal fusion and intercellular penetration. Furthermore, CA-loaded TAT-ePELNs demonstrate significant efficacy in mitigating UVA-induced photoaging. Collectively, this study expands the anti-UVR damage application spectrum of CA from UVB to UVA exposure and establishes a green, efficient, and biosafe strategy for transdermal drug delivery by utilization of non-PELNs generated during the preparation process of PELNs.\n\nID: 42503985\nTitle: [Morphology and anatomical variations of the left gastric vein].\nAbstract: Objective: To explore the gross morphology and variation characteristics of the left gastric vein (LGV) by means of cadaveric anatomical measurement and three-dimensional imaging reconstruction. Methods: A total of 39 adult cadaver specimens fixed with 4% formaldehyde solution from Zhongshan School of Medicine, Sun Yat-sen University, and 40 cases of abdominal contrast-enhanced CT imaging data of patients with gastric cancer admitted to the Seventh Affiliated Hospital of Sun Yat-sen University between January 2023 and December 2024 were included in this study. Specimens with obvious decomposition, tissue deformation, structural damage, or a history of upper abdominal surgery were excluded; patients with pathologically confirmed gastric cancer and CT images suitable for three-dimensional vascular reconstruction were selected, while those complicated with liver cirrhosis, portal hypertension, or a history of major upper abdominal surgery were excluded. The perigastric and perihepatic vessels were exposed in cadaver specimens to observe the morphology and course of the LGV and measure related anatomical parameters; the imaging data were scanned with dual-source CT using standardized parameters, and three-dimensional vascular reconstruction was performed on a post-processing workstation. The LGV was classified according to the Lee criteria. Results: Cadaveric dissection showed that the LGV originated from the middle of the lesser curvature of the stomach, coursed leftward along the lesser curvature, received 2-3 esophageal veins at the inferior margin of the esophageal hiatus, and then obliquely descended rightward to drain into the hepatic portal vein. Both cadaveric dissection and imaging detected three drainage sites of the LGV: the hepatic portal vein, the portal vein angle, and the splenic vein. CT angiography (coronal plane) and cadaver specimens both showed that the proportion of drainage into the hepatic portal vein was the highest [52.5% (21/40) vs. 53.8% (21/39)], followed by the splenic vein [35.0% (14/40) vs. 41.0% (16/ 39)], and the least common was drainage into the portal vein angle [12.5% (5/40) vs. 5.1% (2/39)]. The length of the LGV was (40.3\u00b17.4) mm in cadaver specimens and (48.4\u00b111.9) mm on imaging; the distance from the drainage site to the portal vein angle was (13.8\u00b18.1) mm in cadaver specimens and (13.1\u00b18.2) mm on imaging. In both the imaging group and the cadaver group, the type Ip accounted for the highest proportion of LGV classification, at 40.0% (16/40) and 41.0% (16/39), respectively, and no type IV was detected in either group. The proportion of type II in the imaging group was 22.5% (9/40), which was higher than that in the cadaver group (7.7%, 3/39); the proportion of type Ia in the cadaver group was 25.6% (10/39), which was higher than that in the imaging group (15.0%, 6/40); the proportions of type IIIa (20.0% in the imaging group vs. 20.5% in the cadaver group) and type IIIp (2.5% in the imaging group vs. 5.1% in the cadaver group) were similar between the two groups. Conclusions: There are certain variations in the anatomical course and diameter of the LGV. The LGV most commonly drains into the hepatic portal vein, and is mainly classified as type I. \u76ee\u7684\uff1a \u91c7\u7528\u5c38\u4f53\u89e3\u5256\u5b66\u6d4b\u91cf\u4e0e\u5f71\u50cf\u5b66\u4e09\u7ef4\u91cd\u5efa\u7684\u65b9\u6cd5\uff0c\u63a2\u7a76\u80c3\u5de6\u9759\u8109\u5927\u4f53\u5f62\u6001\u548c\u53d8\u5f02\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u672c\u7814\u7a76\u7eb3\u5165\u4e2d\u5c71\u5927\u5b66\u4e2d\u5c71\u533b\u5b66\u9662\u768439\u5177\u7ecf4%\u7532\u919b\u6eb6\u6db2\u56fa\u5b9a\u7684\u6210\u4eba\u5c38\u4f53\u6807\u672c\u4ee5\u53ca\u4e2d\u5c71\u5927\u5b66\u9644\u5c5e\u7b2c\u4e03\u533b\u9662\u4e8e2023\u5e741\u6708\u81f32024\u5e7412\u6708\u671f\u95f4\u6536\u6cbb\u768440\u4f8b\u80c3\u764c\u60a3\u8005\u8179\u90e8\u589e\u5f3aCT\u5f71\u50cf\u8d44\u6599\u3002\u6807\u672c\u6392\u9664\u8150\u8d25\u53d8\u5f62\u3001\u7ed3\u6784\u635f\u6bc1\u53ca\u6709\u4e0a\u8179\u90e8\u624b\u672f\u53f2\u8005\uff1b\u60a3\u8005\u9009\u53d6\u75c5\u7406\u786e\u8bca\u80c3\u764c\u3001CT\u56fe\u50cf\u53ef\u5b8c\u6210\u8840\u7ba1\u4e09\u7ef4\u91cd\u5efa\u75c5\u4f8b\uff0c\u6392\u9664\u5408\u5e76\u809d\u786c\u5316\u3001\u95e8\u9759\u8109\u9ad8\u538b\u53ca\u4e0a\u8179\u90e8\u91cd\u5927\u624b\u672f\u53f2\u8005\u3002\u5bf9\u5c38\u4f53\u6807\u672c\u89e3\u5256\u66b4\u9732\u80c3\u5468\u53ca\u809d\u5468\u8840\u7ba1\uff0c\u89c2\u5bdf\u80c3\u5de6\u9759\u8109\u5f62\u6001\u8d70\u884c\u5e76\u6d4b\u91cf\u76f8\u5173\u89e3\u5256\u53c2\u6570\uff1b\u5f71\u50cf\u5b66\u8d44\u6599\u91c7\u7528\u53cc\u6e90CT\u89c4\u8303\u53c2\u6570\u626b\u63cf\uff0c\u7ecf\u540e\u5904\u7406\u5de5\u4f5c\u7ad9\u884c\u8840\u7ba1\u4e09\u7ef4\u91cd\u5efa\u3002\u53c2\u7167Lee\u6807\u51c6\u5bf9\u80c3\u5de6\u9759\u8109\u8fdb\u884c\u5206\u578b\u3002 \u7ed3\u679c\uff1a \u5c38\u4f53\u6807\u672c\u89e3\u5256\u663e\u793a\uff0c\u80c3\u5de6\u9759\u8109\u59cb\u4e8e\u80c3\u5c0f\u5f2f\u4e2d\u90e8\uff0c\u6cbf\u80c3\u5c0f\u5f2f\u5de6\u884c\uff0c\u4e8e\u98df\u7ba1\u88c2\u5b54\u4e0b\u7f18\u6536\u7eb32~3\u6761\u98df\u7ba1\u9759\u8109\uff0c\u7ee7\u800c\u5411\u4e0b\u659c\u884c\u5411\u53f3\u6c47\u5165\u809d\u95e8\u9759\u8109\u3002\u5c38\u4f53\u89e3\u5256\u548c\u5f71\u50cf\u5b66\u5747\u6d4b\u5f97\u80c3\u5de6\u9759\u8109\u6c47\u5165\u70b9\u4f4d\u7f6e\u6709\uff1a\u809d\u95e8\u9759\u8109\u3001\u95e8\u9759\u8109\u89d2\u3001\u813e\u9759\u8109\u3002CT\u8840\u7ba1\u5f71\u50cf\uff08\u51a0\u72b6\u9762\uff09\u548c\u5c38\u4f53\u6807\u672c\u5747\u663e\u793a\uff0c\u6c47\u5165\u809d\u95e8\u9759\u8109\u7684\u6bd4\u4f8b\u6700\u9ad8\uff3b\u5206\u522b\u4e3a\uff1a52.5%\uff0821/40\uff09\u300153.8%\uff0821/39\uff09\uff3d\uff0c\u5176\u6b21\u662f\u813e\u9759\u8109\uff3b\u5206\u522b\u4e3a\uff1a35.0%\uff0814/40\uff09\u300141.0%\uff0816/39\uff09\uff3d\uff0c\u6700\u5c11\u6c47\u5165\u5230\u95e8\u9759\u8109\u89d2\uff3b\u5206\u522b\u4e3a\uff1a12.5%\uff085/40\uff09\u30015.1%\uff082/39\uff09\uff3d\u3002\u80c3\u5de6\u9759\u8109\u7684\u5c38\u4f53\u6807\u672c\u957f\u5ea6\uff0840.3\u00b17.4\uff09mm\uff0c\u5f71\u50cf\u5b66\u4e3a\uff0848.4\u00b111.9\uff09mm\uff0c\u6c47\u5165\u70b9\u4e0e\u95e8\u9759\u8109\u89d2\u8ddd\u79bb\uff0813.8\u00b18.1\uff09mm\uff0c\u5f71\u50cf\u5b66\u4e3a\uff0813.1\u00b18.2\uff09mm\u3002\u5f71\u50cf\u7ec4\u4e0e\u5c38\u4f53\u6807\u672c\u7ec4\u80c3\u5de6\u9759\u8109\uff08\u80c3\u5de6\u9759\u8109\uff09\u5206\u578b\u5747\u4ee5\u2160p\u578b\u5360\u6bd4\u6700\u9ad8\uff0c\u5206\u522b\u4e3a40.0%\uff0816/40\uff09\u4e0e41.0%\uff0816/39\uff09\uff0c\u4e14\u5747\u672a\u68c0\u51fa\u2163\u578b\u3002\u5f71\u50cf\u7ec4\u4e2d\u2161\u578b\u5360\u6bd4\u4e3a22.5%\uff089/40\uff09\uff0c\u9ad8\u4e8e\u6807\u672c\u7ec4\u76847.7%\uff083/39\uff09\uff1b\u800c\u2160a\u578b\u5360\u6bd4\u5728\u6807\u672c\u7ec4\u4e3a25.6%\uff0810/39\uff09\uff0c\u9ad8\u4e8e\u5f71\u50cf\u7ec4\u768415.0%\uff086/40\uff09\uff1b\u4e24\u7ec4\u95f4\u2162a\u578b\uff08\u5f71\u50cf\u7ec420.0%\u3001\u6807\u672c\u7ec420.5%\uff09\u4e0e\u2162p\u578b\uff08\u5f71\u50cf\u7ec42.5%\u3001\u6807\u672c\u7ec45.1%\uff09\u5360\u6bd4\u76f8\u8fd1\u3002 \u7ed3\u8bba\uff1a \u80c3\u5de6\u9759\u8109\u89e3\u5256\u8d70\u884c\u53ca\u7ba1\u5f84\u5b58\u5728\u4e00\u5b9a\u53d8\u5f02\uff0c\u80c3\u5de6\u9759\u8109\u6c47\u5165\u809d\u95e8\u9759\u8109\u6bd4\u4f8b\u6700\u9ad8\uff0c\u5206\u578b\u4ee5\u2160\u578b\u4e3a\u4e3b\u3002.\n\nID: 42501862\nTitle: The gut microbiota metabolite IAA modulates gut-brain axis to alleviate reproductive endocrine dysfunction in PCOS.\nAbstract: Circadian rhythm disruption (CD) and gut microbiota dysbiosis are emerging drivers of the polycystic ovary syndrome (PCOS). However, the specific microbial metabolites mediating the gut-brain-ovary axis remain poorly defined, limiting the development of targeted microecological therapies. We aimed to identify the functional role of the gut microbiota-derived metabolite indole-3-acetic acid (IAA) in PCOS, dissecting its peripheral and central mechanisms in ameliorating reproductive-endocrine phenotypes. Multi-omics analyses of clinical PCOS cohorts (feces, serum, follicular fluid) were integrated with CD and DHEA-induced rodent models. Mechanistic pathways were dissected using microbiota-depleted (ABX) models, pharmacokinetic profiling, in vivo chemogenetics via Fos-CreERT2 transgenic mice, and gene silencing (Clock siRNA) in vitro, combined with histological and immunological evaluations. We established the essential role of the gut microbiota in development of CD-induced PCOS phenotypes in rats. Integrating this finding with multi-omics profiling, we identified a profound impairment in indole biosynthesis, characterized by significantly diminished serum IAA levels in both PCOS rat models and clinical patients. Exogenous IAA supplementation across multiple PCOS rodent models ameliorated hyperandrogenism, restored estrous cyclicity, and improved ovarian pathology. Mechanistically, IAA exerted an integrated protective effect across the gut-brain axis. Locally, IAA reinforced intestinal barrier integrity via a CLOCK-dependent pathway, restricting lipopolysaccharide (LPS) translocation and systemic inflammation. Concurrently, IAA treatment suppressed the pathological hyperactivity of ventromedial hypothalamus (VMH) neurons. Crucially, the therapeutic efficacy of IAA was neutralized in microbiota-depleted models, indicating that its restorative function is fundamentally contingent upon a pre-existing dysbiotic context. Our study suggests that the gut microbiota plays a pivotal role in mediating CD-induced PCOS-like phenotypes. IAA functions as a crucial microbial mediator that alleviates PCOS by concurrently restoring peripheral intestinal barriers, dampening systemic inflammation, and rectifying central VMH neuroendocrine hyperactivity. These findings highlight IAA as a microbiota-dependent precision modulator for resetting the gut-brain-ovary axis in PCOS.\n\nID: 42501008\nTitle: Targeting the microbiota-gut-brain axis in neurodegeneration: Zebrafish-based investigations.\nAbstract: The microbiota-gut-brain axis (MGBA) is a bidirectional signaling pathway regulated by the gut microbiome and the central nervous system (CNS). Moreover, MGBA is crucial for normal growth, development, and physiology of the brain and gut of the host; dysfunction in MGBA has been closely linked with the development of neurological disorders. Gut dysbiosis and its metabolites modulate barrier permeability and cause gastrointestinal tract (GIT) inflammation, which is followed by an increase in pro-inflammatory cytokines, immune cell infiltration into the brain, and vagus nerve dysfunction, resulting in neuroinflammation and neuronal defects in the brain, as well as some other behavioral defects. In this review, we will discuss the molecular and neurobehavioral properties of Zebrafish as a research model to study MGBA, as well as current discoveries in humans, highlighting the vital role of MGBA in neuropathological conditions. Using Zebrafish as a genetic model in combination with in vivo imaging technology may suggest some novel mechanisms for the interaction between gut microbiota and CNS, particularly in the case of neurological disorders including Alzheimer's disease (AD), Parkinson's disease (PD) and autism spectrum disorder (ASD). A comprehensive literature search was conducted using electronic databases including PubMed, Scopus, Web of Science, and Google Scholar.\n\nID: 42500659\nTitle: Clinical advances and multifactorial pathophysiological mechanisms of neuropsychiatric comorbidity in systemic sclerosis.\nAbstract: This review addresses the high prevalence of depression and anxiety in systemic sclerosis (SSc), as well as the core biological, psychological and social mechanisms underlying such psychiatric comorbidities, The prevalence of clinically significant depression or anxiety disorders reaches 30%-50% among patients with SSc who satisfy corresponding diagnostic criteria. Established risk factors encompass multi-organ involvement (e.g., lung fibrosis, digital ulcers), chronic pain, physical disability and disease-related stigma. Three key pathophysiological mechanisms drive this comorbidity: immune dysregulation induces neuroinflammation via pro-inflammatory cytokines (IL-6, TNF-\u03b1), pathogenic autoantibodies and gut-brain axis disruption; cerebral microvascular damage and chronic hypoxia impair emotion-regulating neural circuits; tissue fibrosis and persistent stress over activate the HPA axis, forming a pathogenic cycle connecting systemic inflammation, glucocorticoid resistance and negative mood. Clinical management of SSc should extend beyond conventional antidepressants and cognitive behavioral therapy to include integrated rheumatology-psychiatry care, IL-6/JAK-targeted biologics and transcutaneous vagus nerve stimulation (tVNS), all designed to ameliorate patients' physical and psychiatric symptoms simultaneously. In conclusion, psychiatric comorbidity in SSc stems from the intricate interplay of biological, psychological and social factors. Elucidating these mechanisms facilitates the development of targeted therapeutic strategies that address both systemic SSc manifestations and associated mental health conditions, thereby enhancing patients' health-related quality of life and long-term psychiatric outcomes.\n\nID: 42499636\nTitle: Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights.\nAbstract: This review summarizes the potential genes involved in both Parkinson's disease (PD) pathogenesis and colorectal cancer (CRC) carcinogenesis, focusing on the oncogenic mechanisms that may arise from PD gene dysfunctions. By investigating genes such as PRKN, PINK1, and DJ-1, which influence pathways primarily related to oxidative stress, mitophagy, cell cycle regulation, and inflammation, this review provides insight into how PD genes may contribute to CRC tumorigenesis through interactions with gut microbes such as Bacillus subtilis and Clostridium butyricum. This review highlights a mechanistic bridge between neurodegeneration and cancer centered on mitochondrial dysfunction, mitophagy, and inflammation. The convergence of molecular mechanisms and gut microbiota in PD and CRC highlights promising avenues for microbiome-targeted interventions alongside genetic and molecular approaches to advance novel diagnostic and therapeutic strategies for these two diseases. Importantly, therapeutic strategies should be considered in a holistic manner, as interventions for one disease may influence the course of another, and probiotics represent a unique modality with the potential to confer preventive and therapeutic benefits across both conditions.\n\nID: 42495768\nTitle: Chronic kidney disease\u2011associated encephalopathy: Clinical features, pathomechanisms and emerging therapeutic strategies (Review).\nAbstract: Chronic kidney disease (CKD) is a progressive disorder whose systemic effects extend to the central nervous system, leading to CKD\u2011associated encephalopathy. Epidemiological data indicate that the prevalence of cognitive impairment in patients with CKD is as high as 40%, while mood disorders such as depression and anxiety exceed 60% among those receiving hemodialysis, and the risk of cerebrovascular events is also notably increased. These complications substantially impair the quality of life of patients, functional independence and long\u2011term prognosis, thereby constituting a considerable clinical burden. The key pathological mechanisms involve disruption of the 'gut\u2011kidney\u2011brain axis'. Declining renal function leads to the accumulation of gut microbiota\u2011derived uremic toxins, such as indoxyl sulfate, p\u2011Cresyl sulfate and trimethylamine N\u2011oxide. Through multiple pathways, including disruption of blood\u2011brain barrier integrity, induction of neuroinflammation, promotion of oxidative stress and direct neurotoxicity, these toxins collectively contribute to the injury of the neurovascular unit, neuronal dysfunction and even neurodegeneration. The present review systematically outlines the clinical manifestations, the aforementioned core pathogenic mechanisms and emerging therapeutic strategies for CKD\u2011associated encephalopathy. Clinically, early identification of neurological complications (such as through neuropsychological assessment, gait analysis and neuroimaging), along with monitoring of specific biomarkers, is crucial for timely intervention and improved prognosis. In terms of treatment, the targeted interventions on the gut\u2011kidney\u2011brain axis (such as specific probiotics and intestinal adsorbents), and the advantages and disadvantages of stem cells and gene therapy are summarized in the present review. A deeper understanding of these mechanisms will provide a solid theoretical foundation for the development of innovative treatments and ultimately improve neurological outcomes in patients with CKD.\n\nID: 42539791\nTitle: Inflammatory Bowel Disease and Risk of Periprosthetic Joint Infection After Total Joint Arthroplasty: A Systematic Review of the Current Literature.\nAbstract: Periprosthetic joint infection (PJI) is a severe complication after total joint arthroplasty (TJA). Inflammatory bowel disease (IBD) may plausibly increase this risk because of chronic systemic inflammation, intestinal barrier dysfunction, malnutrition, and exposure to immunosuppressive therapies; however, the available orthopedic literature is sparse and heterogeneous. This systematic review was revised in accordance with PRISMA 2020 principles and the PRISMA 2020 for Abstracts recommendations. The primary review question was whether patients with IBD undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) are at increased risk of PJI or septic revision. Cohort and case-control studies reporting arthroplasty-related infectious outcomes in patients with Crohn's disease, ulcerative colitis, or unspecified IBD were eligible for the primary analysis. To ensure the study is scientifically sound, case reports describing nonprosthetic osteomyelitis were excluded from the primary quantitative analysis and evaluated separately using CARE principles as contextual qualitative evidence. No prospective protocol registration was completed before the original review process. The revised review identified two retrospective cohort studies suitable for the primary analysis and two case reports retained in a separate qualitative appendix. The primary analysis included 22,320 arthroplasty patients with IBD studied against much larger non-IBD comparator cohorts. One THA registry study found a higher risk of septic revision in patients with IBD, whereas one TKA database study found higher postoperative PJI odds in both Crohn's disease and ulcerative colitis. Direct quantitative pooling was considered inappropriate because the studies differed in joint type, follow-up duration, and outcome definition. The currently available evidence suggests that IBD may be associated with an increased risk of infection-related failure after arthroplasty, but the certainty of evidence is low to very low because only two retrospective cohort studies directly addressed this question. Future research should use standardized PJI definitions, report disease activity and immunosuppressive treatment in detail, and prospectively evaluate whether the excess risk is related to IBD itself or to modifiable perioperative factors.\n\nID: 42539437\nTitle: Gastrointestinal axis in post-traumatic sepsis: from molecular mechanisms to translational perspectives.\nAbstract: Post-traumatic sepsis is the leading cause of late mortality in intensive care units. While the concept of \"gut-origin sepsis\" has evolved over the past three decades, the stomach has largely been overlooked as an active contributor. This review synthesizes current evidence and proposes a novel \"Gastrointestinal Axis\" (GIA) integrating gastric and intestinal dysfunction as interconnected drivers of post-traumatic sepsis, with gastric autophagy as a proposed regulatory node. The mechanistic data supporting this framework derive primarily from intestinal epithelial cells and general sepsis models; direct evidence for gastric mucosal autophagy in human post-traumatic sepsis remains limited, and the causal inference that gastric autophagy failure initiates downstream intestinal injury remains a hypothesis requiring further validation. A comprehensive literature search of PubMed, Web of Science, and Scopus was conducted to identify relevant peer-reviewed studies on gut barrier dysfunction, dysbiosis, autophagy, and immune responses in post-traumatic sepsis. The central mechanistic framework involves histone deacetylase 5 (HDAC5) upregulation silencing ghrelin, thereby impairing gastric autophagy-a proposed regulatory node in the GIA-which reduces E2F1-mediated NF-\u03baB suppression and impairs intestinal barrier integrity. Parallel protective pathways include PLK1-mTOR-regulated autophagy and SIRT3-mediated mitochondrial protection. This gastric dysfunction may propagate to the intestine, where dysbiosis with loss of obligate anaerobes and overgrowth of Enterobacteriaceae creates a \"pathobiome\" that potentially amplifies systemic inflammation. Bidirectional communication occurs via lymphatic, humoral, cellular, and neural routes. Emerging biomarkers such as intestinal fatty acid-binding protein, D-lactate, citrulline, and the Acute Gastrointestinal Injury grading system enable multimodal risk stratification. Early enteral nutrition (OR 0.36) and synbiotics (RR 0.61) show promise; preclinical data support HDAC5 inhibitors, ghrelin restoration, and teprenone as promising adjuncts for preserving GIA integrity. The GIA concept reframes gastric and intestinal protection as an integrated therapeutic strategy and provides a new conceptual foundation for preventing post-traumatic sepsis and guiding biomarker-driven mechanism-based interventions.\n\nID: 42535828\nTitle: Microalgae Hybrid Biosystem for Enhanced Oral Delivery of Rifaximin in Hepatic Encephalopathy Treatment.\nAbstract: Hepatic encephalopathy (HE) is a serious neuropsychiatric complication of acute or chronic liver failure. It occurred in approximately 40% of acute liver failure cases and affected 30%-45% of patients with chronic liver failure or decompensated cirrhosis. Hyperammonemia is widely recognized as a central pathogenic factor in the pathogenesis of HE. Rifaximin (RIF), a non-absorbable oral antibiotic, was widely used to manage HE by modulating gut microbiota and reducing ammonia production. However, its clinical efficacy remained suboptimal due to poor aqueous solubility, limited dispersibility, and inadequate gastrointestinal retention. These limitations were further exacerbated in severe cases, owing to restricted oral dosing, recurrence associated with poor adherence, and potential risks of antimicrobial resistance and infection-related adverse events. This study presented a microalgae-nanoparticle hybrid system (SP@RIF) for drug delivery, in which RIF-encapsulated nanoparticles (RIFnano) were electrostatically loaded onto the surface of Spirulina platensis (SP), aiming to improve the oral delivery and therapeutic efficiency in HE treatment. RIFnano exhibited significantly enhanced antibacterial activity compared to free RIF. SP@RIF demonstrated prolonged gastrointestinal retention and sustained drug release profiles. In mouse models of HE, oral administration of SP@RIF markedly reduced systemic ammonia levels and improved behavioral outcomes. Furthermore, SP@RIF enhanced intestinal barrier function, attenuated systemic inflammation and neuroinflammation, ameliorated cognitive impairments, and modulated the gut microbiota. Importantly, these therapeutic benefits were achieved without observable toxicity. These findings highlight SP@RIF as a potential therapeutic strategy for treating HE.\n\nID: 42534787\nTitle: Microbiota-derived metabolites and cognitive dysfunction in dialysis patients: mechanisms and targeted therapeutic strategies.\nAbstract: Cognitive impairment (CI) in dialysis patients is a common and serious complication that significantly affects prognosis, with lack of effective treatment strategies. However, its mechanisms are still not fully clear, and effective treatment strategies are still limited. In recent years, more evidence has suggested that gut microbiota dysbiosis and changes in gut-derived metabolites may be involved in the development of CI in dialysis patients through the microbiota-gut-kidney-brain axis. Recent studies have shown that gut microbiota dysbiosis in dialysis patients may promote the progression of CI through several pathways. These include the accumulation of gut-derived uremic toxins, such as indoxyl sulfate (IS), p-cresyl sulfate (PCS), and Trimethylamine N oxide (TMAO), changes in bile acid metabolism; and the reduction of short-chain fatty acids (SCFAs) with neuroprotective effects. These changes may damage the intestinal barrier and the blood-brain barrier (BBB), and promote systemic inflammation, oxidative stress, and neuroinflammation. As a result, cognitive dysfunction in dialysis patients may be further aggravated. Therefore, targeting the gut microbiota has become a promising treatment direction. These strategies include dietary intervention, probiotics and related preparations, fecal microbiota transplantation (FMT), and targeted removal of uremic toxins and their derivatives. This review summarizes the gut microbiota composition associated with CI in dialysis patients, examines the molecular mechanisms of injury mediated by the microbiota-gut-brain-kidney axis, evaluates current microbiota-targeted interventions, and discusses future research directions for improving clinical prevention and treatment.\n\nID: 42534522\nTitle: Ginseng-derived exosomes loaded in fibrin gel promote retinal ganglion cell survival in glaucoma by exerting anti-inflammatory effects through modulating microglial polarization.\nAbstract: Glaucoma is the leading cause of irreversible blindness globally. Chronic neuroinflammation drives progressive retinal ganglion cell (RGC) loss independent of intraocular pressure, yet safe, sustained and precise neuroprotective modulation of the retinal inflammatory microenvironment remains a significant challenge. We developed an injectable fibrin gel delivery system loaded with ginseng-derived exosomes (GE-fibrin gel, GE-gel) to modulate microglial polarization, reduce retinal inflammation and promote RGC survival. In vitro, GE showed strong antioxidant and anti-apoptotic effects by getting rid of reactive oxygen species caused by oxidative stress and lowering apoptosis in R28 cells. Both GE and GE-gel stopped lipopolysaccharide from causing pro-inflammatory M1 polarization of microglia and increased anti-inflammatory M2 phenotypic change. Intravitreal injection of GE-gel suppressed pro-inflammatory microglial activation, diminished neuroinflammation and improved the survival of RGCs in a chronic ocular hypertension rat model. These results show that GE-gel could promote microglial polarization, change the immune environment in the retina and protect RGCs functionally over the long term. This approach may hopefully provide promising solutions for rapid and effective glaucoma therapy.\n\nID: 42532227\nTitle: Steaming reduces Polygonum multiflorum hepatotoxicity by modulating gut microbiota-bile acid-FXR/NF-\u03baB signaling in the gut-liver axis.\nAbstract: Polygonum multiflorum Thunb. (PM) can induce hepatotoxicity, particularly with prolonged use. Traditional processing methods, notably steaming (SPM) and steaming with black bean decoction (PPM), are recognized for their ability to mitigate this toxicity; however, the underlying mechanisms, especially from the gut-liver axis perspective, remain poorly understood. This study aims to clarify the mechanism by which processing reduces PM-induced hepatotoxicity, with a particular focus on the regulation of the gut-liver axis. We employed a comprehensive approach integrating histopathological examination, multi-omics analyses (including 16S rRNA sequencing, transcriptomics, and metabolomics), and molecular analysis to investigate the distinct effects of PM, SPM, and PPM in a mouse model. PM caused significant liver injury, characterized by elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and severe pathological damage. This damage was marked by intestinal barrier disruption (decreased tight junction protein-1 (ZO-1) and occludin), systemic inflammation (elevated tumor necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-6 (IL-6) levels), and activation of the hepatic nuclear factor-kappa B (NF-\u03baB) pathway. Multi-omics analysis revealed that PM induced severe GM dysbiosis (e.g., reduction in the Lactobacillus and a significant increase in the unclassified_f_Oscillospiraceae), a marked decrease in short-chain fatty acids (SCFAs) (e.g., a 72% reduction in butyrate), and disruption of the hepatic bile acid profile. Notably, the two processed products, particularly PPM, significantly reversed these alterations. Compared to the PM group, PPM treatment reduced serum ALT by 82% and exerted extensive protective effects. It restored beneficial bacteria, increased SCFAs levels, normalized bile acid metabolism, and suppressed the hepatic fibrogenic/NF-\u03baB inflammatory axis. This detoxifying effect may be associated with reduced systemic exposure to toxic stilbene glycosides and anthraquinones in the processed PM groups compared to the PM group. This study suggests that processing, particularly with black bean decoction (PPM), can alleviate PM-induced hepatotoxicity by reshaping the GM, restoring its metabolic products (SCFAs), normalizing bile acid signaling, and downregulating the FXR/NF-\u03baB inflammatory axis within the gut-liver axis. These findings provide a mechanistic basis for the clinical preference for processed PM products and highlight the importance of stringent quality control, while also underscoring that residual risk may persist, particularly in susceptible populations.\n\nID: 42530240\nTitle: The Role of Gut Microbiota in Osteoporosis Triggered by High-Fat Diets: Mechanisms and Targeted Therapeutic Strategies.\nAbstract: Overnutrition, and specifically a high-fat diet (HFD) in which more than 30% of energy intake is derived from fat, has been unequivocally identified as a modifiable risk factor for several major diseases including osteoporosis, cardiovascular disorders, diabetes, and metabolic syndrome. The continued rise in prevalence of osteoporosis, particularly among younger populations, along with widespread adoption of HFD, has made the underlying mechanisms and preventative strategies related to HFD-induced osteoporosis a primary focus in the field of bone metabolism research. Early studies suggested that HFD-mediated weight gain might confer protective effects on skeletal health. However, emerging evidence reveals that HFD disrupts bone metabolic homeostasis and accelerates the progression of osteoporosis through multiple pathways, including pathological expansion of adipose tissue, systemic chronic inflammation, and gut microbial dysbiosis. The gut microbiota (GM) is a crucial mediator of dietary fat absorption and is increasingly recognized as a pivotal factor in the pathogenesis of HFD-associated osteoporosis. HFD-induced alterations in gut microbial composition and metabolic function compromise intestinal barrier integrity, triggering chronic systemic inflammation and metabolic disturbances that collectively exacerbate bone loss and promote osteoporosis. Targeted microbiota interventions have shown promise in ameliorating bone deterioration, paving the way for innovative therapeutic approaches against HFD-related osteoporosis. This review systematically examines the pathways through which HFD induces osteoporosis via modulation of GM, and evaluates emerging microbiota-focused treatment strategies.\n\nID: 42529294\nTitle: Effects of probiotic supplementation on gut barrier function in combat athletes during pre-competition weight loss.\nAbstract: Combat sports athletes frequently experience gastrointestinal disturbances during pre-competition weight management. This study aimed to investigate the effects of probiotic supplementation on gut barrier function in combat athletes undergoing rapid weight loss prior to competition. Twenty-four elite male athletes were randomized to receive either a complex sports probiotic (1.5\u202f\u00d7\u202f1010 CFU, twice daily) or placebo for 4 weeks. Results showed that probiotic supplementation significantly reduced gastrointestinal symptoms and gut permeability markers (Zonulin, intestinal fatty acid-binding protein, D-lactate), increased secretory immunoglobulin A (SIgA) levels, and attenuated systemic inflammation compared to placebo. The intervention enriched beneficial butyrate-producing bacteria (Blautia, Latilactobacillus) while suppressing pathogenic Streptococcus. These findings demonstrate that probiotic supplementation serves as a safe, effective nutritional strategy to maintain gut homeostasis during rapid weight loss in combat athletes. http://www.chictr.org.cn, identifier ChiCTR2400079908.\n\nID: 42529164\nTitle: Gut microbiota and intestinal permeability in rheumatoid arthritis: pathogenic mechanisms.\nAbstract: Rheumatoid arthritis is a chronic systemic autoimmune disease in which the earliest breaks in immune tolerance may arise at mucosal surfaces before the clinical onset of synovitis. Among these sites, the gut has emerged as a particularly compelling candidate because it integrates microbial, epithelial, metabolic, and immune pathways with the potential to shape systemic inflammation. In this review, we examine the biological foundations of the gut-joint axis in rheumatoid arthritis, focusing on intestinal barrier structure, microbiome alterations, mucosal immune crosstalk, and mechanisms of barrier dysfunction. Current human evidence links rheumatoid arthritis to heterogeneous shifts in gut microbial composition, depletion of beneficial metabolite-producing commensals, altered immune-metabolic signaling, and biomarker patterns consistent with epithelial injury and microbial-product translocation. At the same time, available data do not support the existence of a single, universal microbial or permeability signature that defines the disease across populations. Recent longitudinal studies further challenge the concept of stable, long-standing dysbiosis and instead suggest a late, transient phase of ecological instability arising close to symptom onset. Experimental models provide stronger mechanistic support, showing that dysbiotic microbial communities, impaired barrier integrity, and strain-specific host-microbe interactions can promote T helper 17-skewed immunity and aggravate arthritis. Collectively, these findings support a context-dependent contribution of the gut to rheumatoid arthritis pathogenesis while underscoring the need for longitudinal, strain-resolved, and multi-omic human studies to clarify causality, refine disease models, and identify clinically meaningful windows for intervention.\n\nID: 42529077\nTitle: Shotgun metagenomic analysis reveals taxonomic and functional alterations in the gut microbiome across prodromal and symptomatic Lewy body disease.\nAbstract: Lewy body disease (LBD) is a progressive neurodegenerative a-synucleinopathy, whereas isolated REM sleep behavior disorder (iRBD) is recognized as a prodromal stage of LBD. Although growing evidence implicates the gut-brain axis in neurodegeneration, the taxonomic and functional roles of the gut microbiome across the prodromal-to-symptomatic LBD continuum remain poorly defined. Here, we performed shotgun metagenomic sequencing on stool samples from 25 patients with LBD (10 mild cognitive impairment due to LBD [MCI-LB] and 15 dementia with Lewy bodies [DLB]), 10 individuals with iRBD, and their household matched cohabitant controls to characterize disease-associated microbial alterations while minimizing environmental confounding. Despite no significant differences in global microbial diversity, we identified convergent shifts in microbial taxa, metabolic pathways, and gene families across disease stages. Both LBD and iRBD showed increased abundance of microbial taxa potentially associated with gut barrier disruption, as well as higher abundance of functional pathways related to lipopolysaccharide biosynthesis. LBD showed lower abundance of pathways related to complex carbohydrate fermentation, and both groups showed lower abundance of pathways associated with neurotransmitter-related metabolism. In particular, pathways and gene families associated with starch degradation were reduced in LBD, and those associated with histidine-to-glutamate/ GABA metabolism were reduced in both groups. These exploratory findings represent the first high-resolution, shotgun metagenomic characterization of gut microbiome alterations across the LBD continuum, highlighting functional patterns that may serve as candidate markers of disease progression in future longitudinal and mechanistic studies.\n\nID: 42524083\nTitle: Pulmonary injury in inflammatory bowel disease: intestinal barrier disruption, gut-lung axis remodeling, and treatment-related lung toxicity.\nAbstract: Inflammatory bowel disease (IBD)-associated pulmonary injury is one of the frequently underestimated extraintestinal manifestations in clinical practice. It can present as subclinical pulmonary function abnormalities, radiographic changes, or overt inflammatory pulmonary diseases and often overlaps with infection- and treatment-related pulmonary toxicity, complicating early recognition and differential diagnosis. Growing evidence indicates that IBD-associated pulmonary injury is not an isolated pulmonary event but rather a cross-organ pathological process jointly driven by disruption of the intestinal mucosal barrier, dysbiosis, and aberrant microbial metabolites, systemic inflammation, and abnormal immune cell trafficking. This article provides a comprehensive review of current basic and clinical research evidence regarding intestinal barrier dysfunction, bidirectional gut-lung axis regulation, immune remodeling mediated by microbial metabolites, such as short-chain fatty acids (SCFAs), and the mechanisms and differential diagnosis of drug-induced pulmonary injury in IBD treatment. Existing studies suggest that SCFAs, tryptophan metabolites, immune cell homing, and alterations in the local pulmonary microbiota may represent key regulatory nodes in IBD-associated pulmonary injury; however, prospective studies integrating intestinal inflammatory activity, circulating biomarkers, pulmonary phenotypes, and drug exposure are still lacking. In the future, emphasis should be placed on establishing a stratified diagnostic framework for distinguishing pulmonary involvement intrinsic to the disease, infection, and drug-induced pulmonary injury, and on evaluating precision intervention strategies targeting microbial function, metabolite supplementation, and barrier repair to advance the translational application of mechanistic research on IBD-associated pulmonary injury into clinical practice.\n\nID: 42523904\nTitle: Gut feelings and sweet teeth: nutritional solutions to the gut damage in inflammatory bowel disease and HIV infection.\nAbstract: Damage to the mucosal layer of the gut is a central feature of chronic inflammatory diseases, often resulting in gut dysbiosis, microbial imbalances, and dysregulated immunometabolism. Gut dysfunction significantly impacts human health, disrupting metabolic, cardiovascular, and neurological systems, and leading to metabolic syndrome. Here, we discuss two clinical entities that are apparently unrelated but actually share similar alterations to gut mucosal barrier integrity: inflammatory bowel disease (IBD) and human immunodeficiency virus (HIV). We use the particular cases of pediatric IBD and nonhuman primate models of HIV infection to compare and contrast the impact of these diseases on gut integrity and microbiome composition. We also explore potential therapies, focusing on dietary interventions. Both HIV infection and IBD cause gut barrier disruption, but via different mechanisms. HIV rapidly depletes mucosal CD4+ T cells (especially Th17 cells), weakening epithelial defenses, leading to a loss of tight junctions (\"leaky gut\"), microbial translocation, and systemic inflammation. In IBD (Crohn's disease and ulcerative colitis), chronic immune attacks on the gut lining produce ulcers and tight-junction defects. These ulcerations trigger immune-cell infiltration and markedly increase permeability. In both conditions, impaired mucus and epithelial integrity result in higher circulating lipopolysaccharides (LPS), macrophage activation, and systemic inflammation. HIV and IBD also induce distinct yet overlapping dysbioses. HIV infection is associated with markedly reduced bacterial diversity and an overgrowth of potentially inflammatory taxa (e.g., Proteobacteria, Prevotella). Similarly, IBD patients have low diversity and loss of beneficial Firmicutes (notably Faecalibacterium prausnitzii) with relative Proteobacteria overabundance. In both diseases, the gut flora shifts away from fiber-fermenting commensals to \"pathobionts,\" fueling local inflammation. While the therapeutic potential of targeting metabolic products is widely explored, there is also a push towards discovering nondrug solutions, particularly through diet and nutrition. We present the effects of micronutrient intake, feeding mechanisms (exclusive enteral nutrition), and different diets (high fiber, Mediterranean, high fat) on disease progression and cellular metabolism. As a low-intervention approach, nutrition has enormous potential to improve human health by reducing inflammation and associated metabolic disturbances. Finally, we emphasize the capabilities of using animal models to elucidate the complexities of disease mechanics in IBD and HIV.\n\nID: 42518164\nTitle: Probiotics and Plant Extracts in the Gut-Brain Axis: Mechanisms, Interactions, and Clinical Perspectives.\nAbstract: Growing evidence highlights the microbiota-Gut-Brain Axis (MGBA) as a critical pathway linking diet to neurological health. This review synthesizes current evidence on the complementary, additive, and potentially synergistic interactions between probiotics and plant-derived phytochemicals within the MGBA. While the individual benefits of these dietary components are well established, their combined synbiotic application offers expanded mechanistic breadth through coordinated modulation of microbial ecology, epithelial barrier integrity, immune inflammatory signaling, and neurochemical pathways. Probiotics and phytochemicals interact bidirectionally via microbial biotransformation, enhancing short-chain fatty acid production, reducing endotoxin translocation, and attenuating systemic and neuroinflammation. These effects are further linked to indirect modulation of neurotransmitter systems and neurotrophic signaling relevant to mood regulation, cognitive function, and neurodegenerative processes. Evidence from preclinical and emerging clinical studies supports the relevance of these mechanisms in conditions such as Alzheimer's disease, Parkinson's disease, mood disorders, and Autism Spectrum Disorder, although human data remain limited. Overall, this narrative review proposes a mechanistic framework describing how probiotics and plant-derived phytochemicals may interact through complementary microbial, immune, and neurochemical pathways within the Microbiota-Gut-Brain Axis. It also highlights current knowledge gaps and emphasizes the need for well-designed clinical studies to validate their combined therapeutic potential.\n\nID: 42514886\nTitle: Anti-Inflammatory Effects of Ginsenoside Rg1 and Low-Dose Ginseng Extract in an Astrocyte-Microglia Co-Culture Model of Inflammation.\nAbstract: Background: Neuroinflammation contributes to the etiopathology and symptom severity of neurodegenerative and neuropsychiatric disorders. Glial cells, especially microglia and astrocytes, play a crucial role in neuroinflammation. It has been reported that ginseng (Panax ginseng) and its bioactive component ginsenoside Rg1 exhibit anti-inflammatory effects and can improve cognitive performance in various models. However, the exact underlying mechanisms remain unclear. Methods: Astrocyte-microglia co-culture models simulating physiological (M5, 5-10% microglia) and pathological/inflammatory (M30, 30-40% microglia) conditions were treated with different concentrations of ginsenoside Rg1 (15, 30, 45 \u00b5M) or ginseng extract (derived from Korean red ginseng) at low (12.5, 25, 37.5 \u00b5g/mL) or high doses (125, 250, 375 \u00b5g/mL) for 24 h. Cell viability was assessed using the MTT assay while microglial reactivity was examined using immunocytochemistry. Astrocytic gap-junctional coupling was investigated using the scrape-loading method, and connexin 43 (Cx43) expression was analyzed using immunocytochemistry and Western blot. Results: Both Rg1 and low-dose ginseng extract reduced microglial activation under inflammatory conditions by promoting a shift in microglia from an activated to homeostatic (resting) phenotype. Rg1 preserved astrocytic gap-junctional function by preventing the inflammation-induced downregulation of Cx43 expression and enhancing Cx43-mediated gap-junctional intercellular communication. Rg1 caused a significant reduction in glial cell viability, but only at high concentrations (30 and 45 \u00b5M), under inflammatory conditions. High-dose ginseng extract showed a significant concentration-dependent reduction in glial cell viability under physiological and pathological conditions, without comparable anti-inflammatory benefits. Conclusions: This study demonstrates that low-dose ginseng and its active compound Rg1 exert anti-inflammatory effects by modulating astrocytic coupling and microglial reactivity. These results provide a novel therapeutic perspective for the use of ginseng in the treatment of neurodegenerative and neuropsychiatric diseases related to neuroinflammation.\n\nID: 42514135\nTitle: Maternal Microbiome in Gestational Diabetes Mellitus: Mechanisms, Biomarkers, and Therapeutic Perspectives.\nAbstract: Gestational diabetes mellitus (GDM) is an increasingly prevalent metabolic disorder of pregnancy, driven by rising maternal age, obesity, and complex metabolic-inflammatory interactions. Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk.\n\nID: 42514045\nTitle: High Humidity Exacerbates Rheumatoid Arthritis in Mice via Prevotella stercorea-Mediated Chondroitin Sulfate Degradation.\nAbstract: Background: Rheumatoid arthritis (RA) is influenced by environmental exposures. High humidity has been clinically associated with worsened joint symptoms, but the microbial and metabolic mechanisms remain unclear. We investigated whether a gut microbiota-metabolism axis contributes to humidity-associated aggravation of collagen-induced arthritis (CIA). Methods: CIA mice were maintained under normal or high relative humidity. We integrated 16S rRNA and metagenomic sequencing, liquid chromatography-tandem mass spectrometry metabolomics, and intestinal barrier assessments. Fecal microbiota transplantation (FMT) was performed to evaluate microbiota dependency. Based on multi-omics findings, we quantified chondroitin sulfate (CS) and conducted functional experiments involving Prevotella stercorea (P. stercorea) supplementation, CS administration, and in vitro degradation assays. Results: High humidity aggravated arthritis severity and systemic inflammation, including increased interleukin-6, interleukin-17A, and granulocyte colony-stimulating factor, and was accompanied by impaired intestinal barrier integrity. FMT supported a microbiota-dependent contribution. Metagenomic analysis identified enrichment of P. stercorea and glycosaminoglycan degradation pathways under high humidity. CS abundance was reduced in articular cartilage, P. stercorea degraded CS in vitro and was associated with cartilage CS loss in vivo, and CS supplementation attenuated arthritis under high humidity and reduced the arthritis-promoting effects associated with P. stercorea. Conclusions: High humidity is associated with microbiota-dependent functional remodeling, enhanced CS degradation, and aggravated arthritis in CIA mice. These findings suggest that humidity-associated alterations in microbial CS metabolism may link environmental exposure to cartilage disruption and joint inflammation.\n\nID: 42542165\nTitle: Multi-omics suggests a pathogenic pathway linking gut dysbiosis, arachidonic acid, and hippocampal ferroptosis in central fatigue.\nAbstract: Central fatigue is a debilitating condition with unclear pathogenesis and limited treatments. Emerging evidence implicates the gut-brain axis in neurological disorders, but its role in central fatigue remains unexplored. This study aimed to elucidate the gut-brain axis in central fatigue via multi-omics and identify potential therapeutic targets. We employed a multi-omics approach in a validated rat model of central fatigue, integrating 16S rRNA sequencing of gut microbiota, untargeted serum metabolomics, and hippocampal transcriptomics. Behavioral tests and fatigue-related biochemical indicators confirmed the central fatigue phenotype. Network analysis connected microbial and metabolic changes. The key findings from the multi-omics analysis were validated through assessments of mitochondrial structure and function, along with molecular expression analyses. Central fatigue was associated with significant gut microbiota dysbiosis and altered serum metabolites, notably an alteration in peripheral arachidonic acid. Multi-omics integration identified a core \"Bacteroides-arachidonic acid\" axis. Hippocampal transcriptomics revealed enrichment in ferroptosis and oxidative phosphorylation pathways. Subsequent validation demonstrated that arachidonic acid activates the ACSL4-ALOX15 pathway, resulting in elevated 15-HETE and ROS levels, along with Fe2+ accumulation, GPX4 downregulation, transferrin upregulation, and mitochondrial dysfunction, which collectively may contribute to hippocampal ferroptosis. Conversely, treatment with the ferroptosis inhibitor ferrostatin-1 significantly restored hippocampal mitochondrial function and ameliorated key behavioral manifestations of central fatigue. This study delineates a novel gut-brain pathway in central fatigue, where microbiota-associated arachidonic acid metabolic alterations are associated with hippocampal ferroptosis, potentially involving the ACSL4-ALOX15-GPX4 pathway. These findings provide new mechanistic insights and therapeutic targets for central fatigue.\n\nID: 42540505\nTitle: Lactiplantibacillus plantarum Probio87 supplementation improves functional constipation and is associated with peripheral gene-expression responses related to inflammation and the gut-brain axis: a randomized, double-blind, placebo-controlled trial.\nAbstract: Functional constipation is a common disorder of gut-brain interaction that substantially affects bowel function, psychological well-being, and quality of life. Probiotic supplementation represents a microbiota-targeted nutritional strategy for functional constipation, but associated host-response signals remain incompletely understood. This single-center, randomized, double-blind, placebo-controlled trial enrolled 104 adults who met the Rome IV criteria for functional constipation. Participants received either Lactiplantibacillus plantarum Probio87 or placebo for 8\u202fweeks, followed by a 4-week post-intervention follow-up. The primary endpoint was weekly complete spontaneous bowel movements. Secondary outcomes included Rome IV symptom scores, PAC-QOL, HAMD-24, safety parameters, and exploratory whole-blood gene-expression profiles related to inflammation, immune regulation, neuroendocrine signaling, and gut motility. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300075360). Probio87 supplementation significantly increased weekly complete spontaneous bowel movements compared with placebo at Week 8 and Week 12. Improvements were also observed in Rome IV symptom scores, constipation-related quality of life, and HAMD-24 domains related to anxiety, sleep, and retardation. Exploratory whole-blood gene-expression analysis showed differential host-response signals after intervention, characterized by increased BDNF expression and reduced expression of IL-1\u03b2, CD117, CXCR5, IDO1, DBH, and MLNR in the probiotic group relative to placebo. No intervention-related adverse events or clinically relevant abnormalities in hematological, hepatic, or renal safety parameters were observed. L. plantarum Probio87 supplementation was associated with sustained improvement in bowel function, constipation-related quality of life, and psychological well-being in adults with functional constipation. Exploratory peripheral gene-expression findings suggest that inflammatory, immune, neuroendocrine, and motility-related host-response pathways may be involved, although causal mechanisms require further validation. https://www.chictr.org.cn/showproj.html?proj=205514, identifier (ChiCTR2300075360).\n\nID: 42535110\nTitle: The vagus nerve as a neurovisceral interface: a comprehensive review.\nAbstract: The vagus nerve is the longest cranial nerve and a key component of the autonomic nervous system, functioning as a neurovisceral interface between the brain and peripheral organs. Despite well-defined anatomy, the mechanisms underlying its integrative roles in cardiovascular, metabolic, and neuropsychiatric regulation remain incompletely understood. This narrative review synthesizes current evidence on the anatomical organization, physiological functions, and clinical relevance of the vagus nerve, focusing on cardiac autonomic control, gastrointestinal and metabolic regulation, the gut-brain axis, and vagus nerve stimulation. In the cardiovascular system, it interacts with sympathetic pathways within the cardiac plexus and intrinsic cardiac nervous system to regulate heart rate and conduction. In the gastrointestinal system, it coordinates motility, secretion, and metabolic homeostasis through nutrient- and hormone-sensitive pathways. Within the gut-brain axis, emerging evidence highlights rapid neuroepithelial signaling and microbiota-dependent modulation mediated by vagal circuits. The vagus nerve stimulation represents a promising therapeutic strategy for restoring autonomic balance, although challenges remain in fiber selectivity and clinical variability. Advances in multi-omics approaches are beginning to reveal the molecular heterogeneity of vagal neurons, but significant gaps persist due to limited human anatomical data. In conclusion, the vagus nerve functions as a multidimensional integrative system, and a deeper understanding of its structure and molecular organization is essential for developing precise neuromodulatory therapies.\n\nID: 42535092\nTitle: Omics research in Parkinson's disease: evolution, integrated analysis, pathogenic mechanisms, biomarkers, and therapeutic targets.\nAbstract: Parkinson's Disease (PD) is a common neurodegenerative disorder that has been widely investigated using omics approaches over 2020-2025. This review focuses on the transition from single-omics to integrative multi-omics analysis, which helps overcome the constraints of individual omics strategies and provides a more systematic understanding of PD pathogenesis. Key topics include the elucidation of core mechanisms (mitochondrial dysfunction, lipid metabolic disturbance, \u03b1-synucleinopathy, and gut-brain axis impairment), the development of biomarkers (shifting from invasive cerebrospinal fluid samples to less invasive plasma/urine panels with improved performance), and the identification of potential interventional targets (signaling pathways, key molecules, and gut microbiota). Technical advances include refined single-omics detection, AI-assisted multi-omics integration, and the emergence of multi-center large cohorts. Despite notable progress, major challenges remain, including limited sample diversity, insufficient technical standardization, and gaps between basic research and clinical translation. Future directions should prioritize the establishment of multi-center longitudinal biobanks, high-sensitivity detection methods, and clinical translation through precision subtyping and targeted intervention. Integrative multi-omics has significantly advanced PD research from fragmented studies to a more systematic framework, providing a foundation for early diagnosis and precision therapy. Further efforts are needed to address current limitations and translate findings into clinical benefit for PD patients.\n\nID: 42533574\nTitle: Metabolomic insights into the response strategies of bats to high-glucose stimulation.\nAbstract: Existing therapeutic options for diabetes remain limited, underscoring the urgent need to explore novel mechanisms for blood glucose regulation. Bats despite diverse dietary habits, making them ideal models for studying hypoglycemic mechanisms. In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Compared with insectivorous bats, frugivorous bats exhibited significantly higher levels of amino acid-related metabolites under high-glucose stimulation. These included N-acyl amino acids, aromatic amino acid derivatives, and branched-chain amino acid metabolites, which were enriched significantly in pathways, such as alanine, arginine, and D-amino acid metabolism. Additionally, several known gut-brain axis (GBA) metabolites-such as neurotransmitters, bile acids, and short-chain fatty acids-exhibited strong host dietary and species specificity. Frugivorous bats were enriched in neurotransmitters and short-chain fatty acids associated with insulin regulation, whereas insectivorous bats exhibited relatively higher levels of bile acid metabolites. Overall, this study provides theoretical insights into the metabolic adaptations of frugivorous bats and the glucose-response strategies of insectivorous bats, offering new perspectives on metabolite-based therapeutic approaches to diabetes. \u73b0\u6709\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u624b\u6bb5\u4ecd\u7136\u6709\u9650\uff0c\u4e9f\u9700\u63a2\u7d22\u8840\u7cd6\u8c03\u63a7\u7684\u65b0\u673a\u5236\u3002\u8759\u8760\u5177\u6709\u9ad8\u5ea6\u591a\u6837\u5316\u7684\u98df\u6027\uff0c\u4e14\u666e\u904d\u8868\u73b0\u51fa\u8f83\u957f\u7684\u5bff\u547d\u7279\u5f81\uff0c\u8fd9\u4f7f\u5176\u6210\u4e3a\u7814\u7a76\u964d\u8840\u7cd6\u8c03\u63a7\u673a\u5236\u7684\u7406\u60f3\u6a21\u578b\u3002\u672c\u7814\u7a76\u5bf9\u4e94\u79cd\u8759\u8760\u5f00\u5c55\u4e86\u8179\u8154\u8461\u8404\u7cd6\u8010\u91cf\u8bd5\u9a8c\uff0c\u5176\u4e2d\u5305\u62ec\u4e09\u79cd\u98df\u679c\u6216\u98df\u871c\u8759\u8760\uff08\u9274\u4e8e\u6c34\u679c\u548c\u82b1\u871c\u5747\u5177\u6709\u8f83\u9ad8\u7684\u7cd6\u542b\u91cf\uff0c\u4e0b\u6587\u7edf\u79f0\u4e3a\u98df\u679c\u6027\u8759\u8760\uff09\u4ee5\u53ca\u4e24\u79cd\u98df\u866b\u8759\u8760\u3002\u91c7\u7528\u6db2\u76f8\u8272\u8c31-\u7535\u55b7\u96fe\u7535\u79bb-\u4e32\u8054\u8d28\u8c31\u6280\u672f\uff08LC-ESI-MS/MS\uff09\u5bf9\u9ad8\u7cd6\u523a\u6fc0\u4e4b\u4e0b\u8759\u8760\u8840\u6e05\u4e2d\u5171704\u79cd\u5df2\u77e5\u4ee3\u8c22\u7269\u8fdb\u884c\u4e86\u5b9a\u91cf\u5206\u6790\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u9ad8\u7cd6\u523a\u6fc0\u4e0b\uff0c\u4e0e\u98df\u866b\u8759\u8760\u76f8\u6bd4\uff0c\u98df\u679c\u8759\u8760\u4f53\u5185\u591a\u79cd\u6c28\u57fa\u9178\u76f8\u5173\u4ee3\u8c22\u7269\u6c34\u5e73\u663e\u8457\u5347\u9ad8\uff0c\u4e3b\u8981\u7c7b\u522b\u5305\u62ecN-\u9170\u57fa\u6c28\u57fa\u9178\u3001\u82b3\u9999\u65cf\u6c28\u57fa\u9178\u884d\u751f\u7269\u4ee5\u53ca\u652f\u94fe\u6c28\u57fa\u9178\u4ee3\u8c22\u7269\uff0c\u8fd9\u4e9b\u4ee3\u8c22\u7269\u663e\u8457\u5bcc\u96c6\u4e8e\u4e19\u6c28\u9178\u3001\u7cbe\u6c28\u9178\u548cD-\u6c28\u57fa\u9178\u4ee3\u8c22\u7b49\u901a\u8def\u3002\u6b64\u5916\uff0c\u591a\u79cd\u5df2\u77e5\u7684\u80a0-\u8111\u8f74\u76f8\u5173\u4ee3\u8c22\u7269\uff08\u5982\u795e\u7ecf\u9012\u8d28\u3001\u80c6\u6c41\u9178\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff09\u8868\u73b0\u51fa\u663e\u8457\u7684\u5bbf\u4e3b\u98df\u6027\u548c\u7269\u79cd\u6c34\u5e73\u7684\u7279\u5f02\u6027\u2014\u2014\u98df\u679c\u8759\u8760\u5bcc\u96c6\u4e86\u66f4\u591a\u7684\u4e0e\u80f0\u5c9b\u7d20\u8c03\u63a7\u76f8\u5173\u7684\u795e\u7ecf\u9012\u8d28\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff0c\u800c\u98df\u866b\u8759\u8760\u5219\u8868\u73b0\u51fa\u6c34\u5e73\u76f8\u5bf9\u66f4\u9ad8\u7684\u80c6\u6c41\u9178\u4ee3\u8c22\u7269\u3002\u603b\u4f53\u800c\u8a00\uff0c\u672c\u7814\u7a76\u4e3a\u63ed\u793a\u98df\u679c\u8759\u8760\u7684\u4ee3\u8c22\u9002\u5e94\u673a\u5236\u53ca\u98df\u866b\u8759\u8760\u7684\u8461\u8404\u7cd6\u5e94\u7b54\u7b56\u7565\u63d0\u4f9b\u4e86\u66f4\u591a\u7406\u8bba\u4f9d\u636e\uff0c\u5e76\u4e3a\u57fa\u4e8e\u4ee3\u8c22\u7269\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u89c6\u89d2\u3002.\n\nID: 42532542\nTitle: [Research progress on the bidirectional relationship between oral infectious diseases and mental health issues].\nAbstract: Infectious oral diseases represent the most prevalent categories of oral conditions, including dental caries, periodontitis, periapical lesions, and pericoronitis. Their bidirectional relationship with mental health has emerged as a critical interdisciplinary research frontier. This paper integrates epidemiological findings and molecular mechanism evidence to analyze the significant comorbidity and correlation characteristics between infectious oral diseases such as caries and periodontitis, and psychological disorders including depression and anxiety. Oral diseases not only directly impair mental well-being through pain, functional impairment, and social anxiety, but also induce systemic inflammatory responses that disrupt the blood-brain barrier, activate microglia, and alter neurotransmitter metabolism, thereby contributing to functional dysregulation within emotional regulatory centers. The dysbiosis of the oral microbiota caused by infectious oral diseases plays a central role in the vicious cycle of \"oral infection-mental health disorders\" through the\"oral-gut-brain axis\", inflammation-mediated neuroimmune cascades, and hypothalamic-pituitary-adrenal axis dysregulation. Meanwhile, mental disorders exacerbate oral microbial imbalance and tissue destruction through poor oral hygiene behaviors, xerostomia induced by psychotropic medications, and stress-related neuroendocrine alterations. This paper advocates for synergistically integrate oral clinical interventions with mental health improvement strategies, and for the development of microbiome-targeted precision modulation approaches. It further proposes an integrated health management paradigm that bridges dentistry and psychiatry, providing both theoretical foundations and practical pathways to transcend traditional disciplinary boundaries and achieve holistic oral-mental co-management. \u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u662f\u53d1\u75c5\u7387\u8f83\u9ad8\u7684\u4e00\u7c7b\u53e3\u8154\u75be\u75c5\uff0c\u4ee5\u9f8b\u75c5\u3001\u7259\u5468\u75c5\u3001\u6839\u5c16\u5468\u75c5\u3001\u51a0\u5468\u708e\u4e3a\u4ee3\u8868\uff0c\u5176\u4e0e\u5fc3\u7406\u75be\u75c5\u7684\u53cc\u5411\u5173\u8054\u5df2\u6210\u4e3a\u8de8\u5b66\u79d1\u7814\u7a76\u7684\u91cd\u8981\u524d\u6cbf\u3002\u672c\u6587\u6574\u5408\u4e86\u6d41\u884c\u75c5\u5b66\u4e0e\u5206\u5b50\u673a\u5236\u7814\u7a76\u8bc1\u636e\uff0c\u5206\u6790\u9f8b\u75c5\u3001\u7259\u5468\u708e\u7b49\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u4e0e\u6291\u90c1\u3001\u7126\u8651\u969c\u788d\u7b49\u5fc3\u7406\u5065\u5eb7\u95ee\u9898\u4e4b\u95f4\u5b58\u5728\u7684\u663e\u8457\u5171\u75c5\u5173\u7cfb\u4e0e\u76f8\u5173\u6027\u3002\u53e3\u8154\u75be\u75c5\u4e0d\u4ec5\u901a\u8fc7\u75bc\u75db\u3001\u529f\u80fd\u969c\u788d\u4e0e\u793e\u4ea4\u7126\u8651\u76f4\u63a5\u635f\u5bb3\u5fc3\u7406\u5065\u5eb7\uff0c\u8fd8\u53ef\u80fd\u8bf1\u53d1\u7cfb\u7edf\u6027\u708e\u75c7\u53cd\u5e94\uff0c\u901a\u8fc7\u7834\u574f\u8840\u8111\u5c4f\u969c\u3001\u6fc0\u6d3b\u5c0f\u80f6\u8d28\u7ec6\u80de\u53ca\u6539\u53d8\u795e\u7ecf\u9012\u8d28\u4ee3\u8c22\u76f4\u63a5\u53c2\u4e0e\u60c5\u7eea\u8c03\u8282\u4e2d\u67a2\u7684\u529f\u80fd\u7d0a\u4e71\u3002\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u6240\u81f4\u7684\u53e3\u8154\u83cc\u7fa4\u7a33\u6001\u5931\u8861\uff0c\u53ef\u901a\u8fc7\u201c\u53e3\u8154-\u80a0-\u8111\u8f74\u201d\u3001\u708e\u75c7\u4ecb\u8d28\u9a71\u52a8\u7684\u795e\u7ecf\u514d\u75ab\u708e\u75c7\u7ea7\u8054\u53cd\u5e94\u4ee5\u53ca\u4e0b\u4e18\u8111-\u5782\u4f53-\u80be\u4e0a\u817a\u8f74\u529f\u80fd\u7d0a\u4e71\u7b49\u5728\u201c\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5-\u5fc3\u7406\u5065\u5eb7\u969c\u788d\u201d\u6076\u6027\u5faa\u73af\u4e2d\u8d77\u5230\u6838\u5fc3\u4f5c\u7528\u3002\u540c\u65f6\uff0c\u5fc3\u7406\u75be\u75c5\u53ef\u901a\u8fc7\u53e3\u8154\u536b\u751f\u884c\u4e3a\u9000\u5316\u3001\u7cbe\u795e\u7c7b\u836f\u7269\u6240\u81f4\u53e3\u5e72\u75c7\u53ca\u5e94\u6fc0\u76f8\u5173\u795e\u7ecf\u5185\u5206\u6ccc\u6539\u53d8\uff0c\u663e\u8457\u52a0\u5267\u53e3\u8154\u83cc\u7fa4\u5931\u8c03\u4e0e\u7ec4\u7ec7\u7834\u574f\u3002\u672c\u6587\u63d0\u51fa\u5e94\u63a8\u52a8\u53e3\u8154\u4e34\u5e8a\u5e72\u9884\u4e0e\u5fc3\u7406\u5065\u5eb7\u6539\u5584\u7684\u534f\u540c\uff0c\u53d1\u5c55\u4ee5\u5fae\u751f\u7269\u7ec4\u4e3a\u9776\u70b9\u7684\u7cbe\u51c6\u8c03\u63a7\u7b56\u7565\uff0c\u6784\u5efa\u878d\u5408\u53e3\u8154\u533b\u5b66\u4e0e\u7cbe\u795e\u533b\u5b66\u7684\u7efc\u5408\u5065\u5eb7\u7ba1\u7406\u8303\u5f0f\uff0c\u4e3a\u7a81\u7834\u4f20\u7edf\u5355\u79d1\u8bca\u7597\u5c40\u9650\u3001\u5b9e\u73b0\u53e3-\u5fc3\u5171\u6cbb\u63d0\u4f9b\u7406\u8bba\u4f9d\u636e\u4e0e\u5b9e\u8df5\u8def\u5f84\u3002.\n\nID: 42532353\nTitle: The Microbiota-Gut-Brain Axis in Neuropsychiatric Disorders: Mechanisms, Advances, and Clinical Applications.\nAbstract: Neuropsychiatric disorders are increasingly recognized as systemic conditions arising from dynamic interactions within the gut-brain-immune network. The Microbiota-Gut-Brain Axis (MGBA) serves as a central regulatory system orchestrating neurodevelopment, neural homeostasis, and immune-metabolic balance. This review summarizes evidence across seven major neuropsychiatric disorders, Depression, Autism Spectrum Disorder, Attention-Deficit/Hyperactivity Disorder, Alzheimer's disease, Schizophrenia, Anxiety and Obsessive Compulsive Disorder, demonstrating that dysregulation of the MGBA constitutes a shared pathological mechanism. On this common basis, we delineate disorder specific neurochemical and immunological features and highlight the clinical potential of microbiota-targeted interventions. Moreover, psychotropic medications profoundly alter microbial physiology, influencing bacterial growth and metabolism, thereby complicating interpretation of MGBA-disease relationships. Future research should define strain-specific therapeutic actions and integrate multi-omics approaches to unravel causal pathways, ultimately enabling precision microbiome modulation in neuropsychiatric medicine.\n\nID: 42530713\nTitle: Integrative Analysis Reveals Interactions Between Gut Microbiota-Derived Metabolites and the Brain in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disorder increasingly associated with gut microbiota alterations, yet the mechanisms by which microbial metabolites influence PD remain unclear. Here, we applied an integrative computational and experimental strategy to identify key gut microbial metabolites and host genes potentially involved in PD. Differentially abundant gut microbes were obtained from the gutMDisorder database and their corresponding metabolites from gutMGene, with predicted protein targets generated using the Similarity Ensemble Approach. Transcriptomic data from PD brain tissues were analyzed to identify differentially expressed genes, which were intersected with metabolite targets, followed by enrichment and protein-protein interaction analyses. Three machine learning algorithms were applied for gene prioritization, while molecular docking evaluated metabolite-gene binding affinities and ProTox3.0 predicted toxicity and blood-brain barrier permeability. In vitro assays further assessed the functional effects of 3-indolepropionic acid in a rotenone-induced SH-SY5Y cell model. Our analyses identified 44 PD-associated microbial taxa linked to 77 metabolites and 905 predicted target genes, with 29 overlapping differentially expressed genes enriched in synaptic signaling and dopaminergic pathways. Dopamine receptor D2 (DRD2) emerged as a central hub gene, with strong docking interactions predicted for two indole metabolites, 3-(1H-indol-3-yl)propanoate and 3-indolepropionic acid. Functional validation showed that 3-indolepropionic acid improved cell viability, reduced apoptosis, and preserved DRD2 expression under neurotoxic stress. Together, these findings suggest that specific gut microbial metabolites may modulate host dopaminergic signaling via DRD2, offering new insights into the microbiota-brain axis and potential targets for further PD research.\n\nID: 42530642\nTitle: The gut microbiota mediates the antidepressant effects of imipramine: Evidence from fecal microbiota transplantation and prebiotic inulin intervention.\nAbstract: Many antidepressants exert their effects by modulating the gut microbiota, but it is unknown if this mechanism extends to the tricyclic antidepressant imipramine. We probed the extent to which specific gut bacterial taxa mediate the antidepressant effects of imipramine. Using a chronic unpredictable mild stress (CUMS) mouse model, we administered imipramine, the prebiotic inulin, or their combination, and systematically evaluated depressive-like phenotypes. Gut microbial dynamics were profiled by 16S rRNA sequencing, and fecal microbiota transplantation (FMT) was performed to determine the transmissibility of microbiota-derived antidepressant effects. Immunofluorescence staining was used to quantify brain-derived neurotrophic factor (BDNF) expression and to assess intestinal barrier integrity via ZO-1 and occludin. Imipramine treatment significantly increased the relative abundances of putative A. muciniphila and L. reuteri, both of which showed strong correlations with behavioral improvements. Furthermore, FMT from imipramine-treated donors effectively alleviated CUMS-induced depressive-like behaviors, upregulated BDNF expression and restored gut barrier integrity in recipient mice. Co-administration of imipramine and inulin produced synergistic antidepressant effects. Imipramine partially exerts its antidepressant activity through microbiota modulation, with putative A. muciniphila and L. reuteri emerging as important mediators. The superior efficacy of the imipramine-inulin combination highlights a promising microbiota-targeted strategy for advancing antidepressant therapy.\n\nID: 42528818\nTitle: Gut microbiota induces immune-related alterations in gene expression, RNA methylation, and metabolism in glioblastoma revealed by single-cell and spatial multi-omics.\nAbstract: Glioblastoma (GBM) is a highly malignant tumor with poor prognosis and limited effective treatment options. Emerging studies have suggested that gut microbiota may influence glioma progression through the gut-brain axis, though the precise mechanisms remain largely unclear. In this study, we employed a comprehensive multi-omics approach-encompassing single-cell transcriptomics, spatial transcriptomics, metagenomics, metabolomics, and m6A-seq-to investigate how antibiotic-induced gut microbiota disruption impacts glioma progression in a mouse model. Gene expression analysis revealed significant alterations in antibiotics-treated mice (ABX-treated mice), including reduced expression of Epha6 and upregulated expression of Tead1, key genes associated with glioma progression and immune modulation. Spatial transcriptomics and metabolomic profiling identified reduced methionine levels in gliomas of ABX-treated mice, linking gut-derived metabolite changes to epigenetic regulation via m6A methylation. Single-cell RNA sequencing further demonstrated an increased proportion of AC-like cells, disrupted intercellular communication, and aberrations in the EPHA and NRXN signaling pathways. These findings highlight the interplay between gut microbiota, immune signaling, and epigenetic modifications in shaping the glioma microenvironment. This study advances our understanding of the gut-brain axis in glioma biology and proposes the EPHA pathway as a promising biomarker for the immune-mediated modulation of tumor progression, thereby providing new insights into the role of the gut-brain axis in glioma regulation.\n\nID: 42528640\nTitle: Huanglian Wendan decoction modulates gut microbiota-brain axis for depression comorbid with insomnia: a mini review.\nAbstract: Depression comorbid with insomnia (DCI) is a highly prevalent mental disorder with complex pathogenesis, posing great clinical challenges for Western medical interventions due to adverse reactions, drug dependence and single targets. Accumulating preclinical evidence confirms the microbiota-gut-brain axis (MGBA) as a core regulatory hub in DCI pathogenesis, with gut microbiota dysbiosis being the initiating factor that disrupts host neuroendocrine, immune and circadian systems via multiple pathways, forming a vicious circle to aggravate DCI symptoms. Huanglian Wendan Decoction (HLWDD), a classic traditional Chinese medicine herbal formula, shows potential therapeutic effects on DCI by targeting the gut microbiota-the core node of MGBA. Notably, most relevant evidence is derived from animal preclinical models. This Mini Review succinctly summarizes the core pathological mechanisms of gut microbiota dysbiosis inducing DCI via MGBA, and elaborates HLWDD's multi-target therapeutic effects on DCI centered on gut microbiota regulation: reshaping gut microbiota composition, promoting short-chain fatty acids (SCFAs) production, and protecting intestinal mucosal barrier integrity, as well as improving central nervous system dysfunction via MGBA bidirectional regulation. We also discuss the existing academic controversies, critical research gaps and potential future development directions in this field. This review highlights the gut microbiota as a key therapeutic target of HLWDD for DCI, and provides a scientific basis for its clinical application and translational research via MGBA modulation.\n\nID: 42526548\nTitle: Forsythiae Fructus attenuates DSS-induced colitis and associated neuroinflammation with modulation of AMPK/mTOR-related autophagy signaling.\nAbstract: Forsythiae Fructus, the dried fruit of Forsythia suspensa (Thunb.) Vahl is a traditional herbal medicine widely used in East Asia for inflammatory disorders. Although Forsythiae Fructus exhibits anti-inflammatory activity in experimental colitis, its effects on colitis-associated brain inflammation and autophagy-related signaling remain unclear. This study investigated the protective effects of Forsythiae Fructus extract (FF) on intestinal and brain inflammatory responses in dextran sulfate sodium (DSS)-induced colitis mice and explored the involvement of AMPK/mTOR-related signaling. Mice received FF (100\u202fmg/kg) or 5-aminosalicylic acid (ASA, 100\u202fmg/kg) by oral gavage once daily for 15 days. DSS (5%, w/v) was administered in drinking water from day 7 to day 12, followed by a 3-day recovery period with normal drinking water (day 12-15). Disease severity, intestinal permeability, inflammatory mediators, and autophagy-related markers in the colon and brain were assessed using endoscopy, histology, ELISA, immunoblotting, immunofluorescence, and RT-qPCR. FF substantially alleviated DSS-induced colitis by attenuating body weight loss (-9.0% vs. -17.1% in DSS), reducing the disease activity index by approximately 40%, increasing colon length by 18%, and decreasing intestinal permeability by approximately 59%. FF restored epithelial barrier integrity by increasing Occludin, ZO-1, Muc2, and Tff3 expression. It also decreased IL-1\u03b2, IL-6, and TNF-\u03b1 levels in the colon, serum, and brain, accompanied by reduced microglial activation and NF-\u03baB signaling. FF increased AMPK phosphorylation and LC3B-II/LC3B-I ratios while reducing mTOR activation and SQSTM1 accumulation in both colon and brain tissues. FF effectively alleviated DSS-induced colitis, reducing disease activity by approximately 40% and restoring intestinal barrier function. These protective effects were accompanied by suppression of intestinal and brain inflammatory responses and modulation of AMPK/mTOR-related autophagy signaling. These findings provide experimental support for the traditional use of FF in inflammatory disorders and highlight its potential as a protective candidate for ulcerative colitis and its associated gut-brain inflammatory manifestations.\n\nID: 42520989\nTitle: Long-term antibiotics treatment-induced anxiety-like behavior is associated with disrupted colonic tryptophan metabolism.\nAbstract: The widespread and often excessive use of antibiotics has raised concerns about its long-term impact on host health. Growing evidence suggests that antibiotics-induced gut microbiota dysbiosis may contribute to neuropsychiatric conditions, including anxiety. However, the mechanistic pathways linking chronic antibiotic exposure, microbial disruption, and anxiety-like behaviors remain largely unclear. To investigate the effects of antibiotic exposure on gut-brain axis function, mice were administered antibiotic-containing drinking water for either short-term or long-term durations. Behavioral assessments, 16S rRNA gene sequencing, biochemical analyses, histological staining, and Western blotting were used to evaluate anxiety-like behaviors, microbiota composition, tryptophan (Trp) metabolism, intestinal barrier integrity, and inflammation in both the colon and hippocampus. Long-term, but not short-term, antibiotic treatment induced pronounced anxiety-like behaviors in mice. Microbiota analysis revealed that long-term antibiotic exposure significantly reduced microbial diversity and altered the abundance of key bacterial genera. These changes were associated with disrupted colonic Trp metabolism, reflected by decreased Trp and 5-HT levels in the colon and serum, along with suppressed expression of the Trp metabolic enzyme TPH1 and 5-HT4R. Additionally, long-term antibiotic treatment impaired intestinal barrier integrity, downregulated tight junction proteins and MUC2, and activated colonic TLR4/NF-\u03baB/NLRP3 inflammatory signaling pathways. Neuroinflammation was also observed in the hippocampus. Our results reveal a time-dependent effect of antibiotic-induced anxiety-like behaviors and suggest that gut microbiota dysbiosis, disrupted colonic Trp metabolism, intestinal barrier dysfunction, and neuroinflammation may collectively contribute to the behavioral alterations associated with long-term antibiotic exposure. These findings provide new insights into the gut-brain mechanisms underlying microbiota-associated mood disorders.\n\nID: 42519705\nTitle: Gut microbiota signatures associated with lithium treatment and clinical response in patients with bipolar disorder.\nAbstract: Lithium, the gold-standard treatment for bipolar disorder, exhibits highly heterogeneous clinical responses and no validated biological predictors of responsiveness are currently available. Emerging evidence suggests that the gut microbiota influences mood disorders and psychotropic drug response, raising the hypothesis that specific microbial signatures may modulate lithium responsiveness. In this study, we characterized taxonomic and functional gut microbiota profiles in 77 patients with bipolar disorder, of whom 40 were receiving lithium (20 responders, 20 non-responders) and 37 were treated with valproate as the main mood stabilizer (valproate, n = 31; lamotrigine, n = 6), with the aim of identifying potential microbial markers of clinical response. Microbiota composition was assessed through 16S rRNA sequencing targeting the V3-V4 region. Differential abundance was evaluated using Analysis of Composition of Microbiomes with Bias Correction (ANCOM-BC2), and the functional potential was inferred using the Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2 (PICRUSt2). Our finding showed that lithium treatment was associated with a selective gut microbiota reorganization, including reduced Actinobacteria (Actinomycetota) phylum, notably Coriobacteriia class, and enrichment in Firmicutes (Bacillota) taxa, including Selenomonadales, Megamonas and Clostridia taxa, alongside reductions in primary fermentative and biosynthetic pathways. This shift, characterized by a reduction of primary fermenters and enrichment of secondary fermenters and SCFA-producing taxa, suggests a more efficient fermentative ecosystem in lithium-treated patients. Responders showed enrichment in methanogenic taxa (Methanobrevibacter) and Clostridiales vadinBB60 group when compared with patients treated with other mood stabilizers; however, these differences were not observed in the direct comparison between lithium responders and non-responders. While causal relationships cannot be inferred, these findings indicate treatment-associated microbial patterns and support further investigation into microbiota-directed adjunctive therapies.\n\nID: 42519496\nTitle: Postoperative hyperinflammation and recovery challenges in necrotizingenterocolitis.\nAbstract: Necrotizing enterocolitis (NEC) remains one of the most devastating gastrointestinal emergencies in neonates, particularly affecting premature infants with immature intestinal, immune and microvascular systems. While surgical intervention is often lifesaving in severe NEC, the postoperative period introduces distinct challenges that critically influence survival and long-term outcomes. This review examines postoperative hyperinflammation as a central driver of morbidity following surgical NEC. Despite resection of necrotic bowel, many infants experience persistent systemic inflammation characterized by dysregulated innate immune activation, excessive cytokine release and sustained gut barrier dysfunction. Key mediators including tumor necrosis factor-alpha (TNF-\u03b1), interleukin (IL)-6, IL-1\u03b2 and IL-8 contribute to endothelial injury, capillary leak, hemodynamic instability and multiorgan dysfunction. Ongoing intestinal permeability and microbial translocation perpetuate inflammatory signaling, delaying mucosal healing and predisposing infants to recurrent NEC, sepsis and short bowel syndrome. Clinically, postoperative hyperinflammation manifests as systemic inflammatory response syndrome, coagulopathy, feeding intolerance, impaired wound healing and neurodevelopmental injury. Recovery is frequently prolonged by nutritional compromise, dependence on parenteral nutrition and recurrent infections, which further amplify inflammatory stress. Current management remains largely supportive, focusing on optimization of nutrition, infection prevention and multidisciplinary care. Emerging immunomodulatory and microbiome-based therapies remain investigational. Postoperative hyperinflammation remains a difficult and complex sequelae of NEC and future investigation is needed to improve long-term outcomes.\n\nID: 42519007\nTitle: Multi-omics profiling reveals gut microbiome signatures associated with cognitive decline in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is increasingly being linked to gut microbial dysbiosis via the gut-brain axis. We applied integrated metagenomics and metabolomics to characterize gut microecology in 28 patients with AD and 33 controls. Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies.\n\nID: 42541189\nTitle: Mycobacterium tuberculosis PPE2 protein-derived peptide ameliorates DSS-induced colitis by depleting mast cells.\nAbstract: In the present study, we demonstrated that a synthetic peptide derived from the Mycobacterium tuberculosis PPE2 protein alleviates dextran sodium sulphate (DSS)-induced colitis in mice and markedly improves ulcerative colitis (UC) symptoms, as evidenced by improvement in body weight loss, disease activity index (DAI) score, colon length, and decrease in myeloperoxidase activity. PPE2-peptide treatment attenuated the induction of pro-inflammatory cytokines, enhanced the mRNA levels of tight junction proteins (Occludin, Claudin-1, and ZO-1), and prevented gut barrier function. PPE2 acts mainly by targeting the mast cells, as adoptive transfer of mast cells restored the symptoms of DSS-induced colitis in PPE2-treated mice. We further explored the development of a combination therapy aimed at targeting multiple pathways involved in inflammatory bowel disease (IBD) pathogenesis and showed that combination therapy of PPE2-peptide and mesalazine had better efficacy in improving UC symptoms. This study highlights a potential therapeutic strategy targeting fibroblast-mast cell crosstalk in IBD.\n\nID: 42537886\nTitle: The study of intestinal toxicity induced by gossypol acetic acid and the mechanism using zebrafish model and network toxicology.\nAbstract: Gossypol acetic acid (GAA), a natural product obtained from the cottonseed, has various bioactivities, including antiviral, anti-tumor and anti-inflammatory properties, among others. However, the potential intestinal toxicity of GAA is poorly studied. Here, the intestinal toxicity and the underlying mechanism were investigated in vivo using zebrafish and network toxicology. After exposure from 3\u202fdays post fertilization (dpf) to 6 dpf, GAA could notably affect the zebrafish gut barrier by reducing the microvilli and goblet cells, and subsequently affected the intestinal function, including decreasing the intestinal peristalsis and peristalsis number, endocytic capacity. In addition, GAA promoted the intestinal infiltration of neutrophil cells and cell death in the intestine. Furthermore, the mechanism study by network toxicology, molecular docking and RT-qPCR, showed that GAA could affect lipid metabolism, redox balance, apoptosis, inflammation and pyroptosis by regulating PPAR/NLRP3/GSDMD pathways. Taken together, these results will help to deeply understand GAA's harmful effects and underlying mechanisms.\n\nID: 42532671\nTitle: Decompression of portal hypertension by transjugular intrahepatic portosystemic shunt reverses markers of gut barrier dysfunction and cirrhosis-associated immune dysfunction.\nAbstract: Decompensated cirrhosis is associated with cirrhosis-associated immune dysfunction (CAID), predisposing patients to bacterial infections and poor outcomes. The mechanisms driving CAID remain incompletely understood. To examine whether portal hypertension (PH) is a key upstream driver of CAID and whether its reduction by transjugular intrahepatic portosystemic shunt (TIPS) reverses immune dysfunction. In a prospective cohort study, patients undergoing TIPS (n=75) and controls with compensated cirrhosis (n=15) were included. Plasma markers of gut barrier dysfunction, bacterial translocation, systemic inflammation and monocyte activation were measured in controls and longitudinally before and after TIPS. The effects of patient sera from different stages of cirrhosis on healthy donor-derived monocytes were assessed in vitro. Bulk RNA sequencing was performed on patient monocytes. Immunological findings were correlated with clinical outcomes, which were also validated in an external prospective cohort and a retrospective multicentre cohort of 1180 patients. Patients with decompensated cirrhosis showed elevated markers of gut barrier dysfunction, bacterial translocation, systemic inflammation and monocyte activation compared with compensated controls. These markers significantly decreased after TIPS. Sera from decompensated patients, but not from post-TIPS patients, induced anti-inflammatory markers (MER Tyrosine Kinase (MERTK), CD163) and suppressed interleukin 6 secretion in monocytes in vitro. Transcriptomic analysis identified an anti-inflammatory monocyte signature in decompensated cirrhosis that resolved after TIPS. CAID improvement occurred only in patients with ascites resolution and was associated with fewer bacterial infections. PH is a central driver of CAID in decompensated cirrhosis. Its reduction by TIPS restores gut barrier integrity, reduces inflammation and re-establishes immune homeostasis.\n\nID: 42531833\nTitle: Poricoic acid a ameliorates ulcerative colitis via AMPK/PPAR\u03b3 pathway-dependent cellular senescence inhibition and concomitant gut microbiota-metabolome modulation.\nAbstract: Ulcerative colitis (UC) is an intractable inflammatory bowel disorder characterized by persistent intestinal inflammation and impaired gut barrier integrity. Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis.\n\nID: 42531785\nTitle: Curdlan alleviates non-alcoholic fatty liver disease by enriching butyrate-producing gut microbiota-liver axis.\nAbstract: The gut microbiota-liver axis is a critical target for non-alcoholic fatty liver disease (NAFLD) intervention, yet effective strategies to restore gut microbiota balance and mitigate hepatic metabolic inflammation remain limited. Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.\n\nID: 42528924\nTitle: Mucosal and systemic immune signatures reveal compartmentalized regulation of gut barrier integrity in virologically suppressed HIV Infection.\nAbstract: Persistent immune activation and inflammation contribute to non-AIDS comorbidities in people living with HIV (PLWH) despite long-term virological suppression. Given the central role of the gut in immune homeostasis, we investigated whether mucosal and peripheral molecular signatures relate to clinical status, immune recovery, and antiretroviral therapy (ART) class. Sixty-eight virologically suppressed PLWH were stratified by CDC clinical stage, ART regimen (integrase strand transfer inhibitor [INSTI]-based vs. non-INSTI), and CD4/CD8 ratio. Targeted gene expression was assessed by RT-PCR in anorectal mucosal biopsies and peripheral blood mononuclear cells, while epithelial protein expression was evaluated by Western blot in mucosal biopsies. Plasma biomarkers of epithelial injury, microbial translocation, and systemic inflammation were quantified by ELISA. Group comparisons and correlation analyses were performed using non-parametric statistics. Mucosal analyses revealed distinct transcriptional and protein-level alterations associated with clinical and immunological stratifications, whereas peripheral cellular and circulating biomarkers showed limited discriminatory capacity. Notably, specific ART-related patterns emerged at the mucosal level, accompanied by coordinated associations between epithelial junctional features and local immune parameters that were not mirrored systemically. Together, these findings indicate persistent, spatially restricted epithelial-immune remodelling in treated HIV infection, underscoring the importance of direct mucosal assessment to capture residual barrier and immune perturbations under suppressive ART.\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.

This review advances an effector-centered framework to explain how A. muciniphila acts through host-facing molecules, including outer membrane and secreted proteins such as Amuc_1100 (pilus-associated signaling, PAS) and P9, extracellular vesicles (EVs) and outer membrane vesicles (OMVs), and shed cell-envelope fragments and lipids. We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release. Key gaps include physiological dose realism, equivalence across colony-forming units (CFU) and protein or vesicle doses, strain and culture-condition dependence of effector expression, and limited human data for brain-relevant endpoints. Effector-defined preparations and engineered delivery systems may improve standardization and safety, but translation will require rigorous characterization, dose-response validation, and mechanism-linked biomarkers.\n --- END ACTUAL ABSTRACT FOR 42528156 ---\n\n- ERROR: You cited ID: 42543328 for the quote: \"Furthermore, impairment of the intestinal barrier results in the translocation of lipopolysaccharide(LPS) into the bloodstream.

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- ERROR: You cited ID: 42531785 for the quote: \"Curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels.\"\n FACT: Strict Misquote Detected!

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.\n --- END ACTUAL ABSTRACT FOR 42531785 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms.\" (Source: 42544276)\n- \"Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection.\" (Source: 41972275)\n- \"PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway.\" (Source: 42531833)\n- \"MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference.\" (Source: 42538615)\n- \"Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals.\" (Source: 42528699)\n- \"These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication.\" (Source: 42543363)\n- \"Exploratory whole-blood gene-expression analysis showed differential host-response signals after intervention, characterized by increased BDNF expression and reduced expression of IL-1\u03b2, CD117, CXCR5, IDO1, DBH, and MLNR in the probiotic group relative to placebo.\" (Source: 42540505)\n- \"First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation.\" (Source: 42526737)\n- \"Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis.\" (Source: 42529162)\n- \"Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses.\" (Source: 42522048)\n- \"These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions.\" (Source: 42505396)\n- \"Oral \u03b2G@Apr-WPG NMs administration outperformed free apremilast by restoring gut barrier integrity, reducing histopathological damage, and modulating microbial dysbiosis.

By utilizing plant-derived agents such as Magnolia biondii-derived exosome-like nanoparticles (MFELNs) or microbial-biotransformed ginsenosides (PPD), researchers have demonstrated effective suppression of neuroinflammatory signaling in the hippocampus and peripheral immune cells, thereby providing a viable strategy to manage neurodegenerative trajectories through the microbiota-gut-brain axis.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the gastrointestinal barrier acts as a fundamental defense against systemic inflammation. As evidenced in the literature, barrier dysfunction leads to the translocation of endotoxins such as LPS, which serves as a potent trigger for the NLRP3 inflammasome and subsequent neuroinflammatory responses. Emerging evidence highlights that MFELNs, derived from *Magnolia biondii*, effectively mitigate colitis by suppressing inflammatory signaling and restoring intestinal barrier proteins. Similarly, the fermentation of ginseng to enrich protopanaxadiol (PPD) transforms it into a potent anti-aging agent that seals the gut and resets redox homeostasis. These agents function by modulating the gut-brain-liver axis, effectively acting as \"molecular bridges\" that prevent the chronic, low-grade systemic inflammation (inflammaging) associated with neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived exosome-like nanoparticles (PELNs) possess a phospholipid bilayer structurally homologous to mammalian cells, enhancing their bioavailability for drug delivery.\n* The gut microbiota serves as an active metabolic site for transforming herbal precursors (e.g., ginsenosides) into active, bioavailable neuroprotective agents.\n* Systemic inflammation in conditions like rheumatoid arthritis is directly linked to the entry of intestine-derived LPS into the bloodstream, establishing a clear gut-joint-brain connection.\n* Chronic fatigue syndrome and obesity-related anxiety share common mechanisms rooted in gut dysbiosis and HPA-axis hyperactivity.\n* Short-chain fatty acids (SCFAs) function as critical mediators in the microbiota-gut-brain axis by preserving blood-brain barrier integrity and modulating glial cell states.\n* The gut-liver axis acts as a key filter; when this filter fails, bile acid metabolism is disrupted, further exacerbating neuroinflammation.\n* Prebiotic interventions can restore the firmicutes/bacteroidota ratio, directly correlating with improved cognitive outcomes.\n* Microbial metabolites from fermentable fibers are essential for suppressing histone deacetylase-mediated neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"40390612": "ID: 40390612\nTitle: [Acupuncture effects and neuro-immune regulation: a breakthrough in \"treating diseases at the root\"].\nAbstract: The holistic philosophy of traditional Chinese medicine (TCM) embodied in acupuncture therapy has gained novel insights within the neuroimmune regulatory framework. Its mechanistic framework encompasses 3 pivotal dimensions: 1) Acupuncture stimulation at acupoints transduces mechanical signals into neuroelectrical and biochemical signals, initiating localized immunomodulatory microenvironment remodeling; 2) The autonomic nervous system orchestrates systemic and organ-specific immune homeostasis through vagus nerve-mediated anti-inflammatory effects and sympathetic nerve-mediated bidirectional regulatory dynamics; 3) The enteric nervous system facilitates barrier restoration via neuropeptide-microbiota crosstalk, establishing bidirectional gut-brain axis immune communication. Emerging bioelectronic devices based on somatosensory-autonomic reflex circuits are driving the evolution of acupuncture from empirical practice to precision neuromodulation. Future research should integrate multi-omics profiling and artificial intelligence algorithms to construct a comprehensive \"mechanical stimulation-neural coding-immune response\" mapping paradigm. This will operationalize TCM's core principle of \"treating the root of disease\" into targeted neuromodulation strategies against inflammatory and immune-related disorders through defined neural circuit interventions. \u9488\u523a\u7597\u6cd5\u6240\u5448\u73b0\u7684\u4e2d\u533b\u6574\u4f53\u89c2\u5ff5\u5728\u795e\u7ecf\u514d\u75ab\u8c03\u63a7\u65b9\u5411\u83b7\u5f97\u5168\u65b0\u89e3\u8bfb\u3002\u5176\u4f5c\u7528\u67b6\u6784\u6db5\u76d6\uff1a\u5c40\u90e8\u7269\u7406\u523a\u6fc0\u4fe1\u53f7\u5411\u795e\u7ecf\u7535\u4fe1\u53f7\u548c\u5316\u5b66\u4fe1\u53f7\u8f6c\u5bfc\uff0c\u9a71\u52a8\u7a74\u533a\u5c40\u90e8\u514d\u75ab\u5fae\u73af\u5883\u91cd\u5851\uff1b\u9488\u523a\u8c03\u63a7\u81ea\u4e3b\u795e\u7ecf\u7cfb\u7edf\u7ecf\u7531\u8ff7\u8d70\u4e0e\u4ea4\u611f\u795e\u7ecf\u534f\u8c03\u5168\u8eab\u7cfb\u7edf\u6027\u4e0e\u5c40\u90e8\u9776\u5668\u5b98\u7684\u514d\u75ab\u7a33\u6001\u5e73\u8861\uff1b\u9488\u523a\u8c03\u63a7\u80a0\u795e\u7ecf\u7cfb\u7edf\u901a\u8fc7\u795e\u7ecf\u80bd-\u83cc\u7fa4\u4ea4\u4e92\u4f5c\u7528\u5b8c\u6210\u5c4f\u969c\u4fee\u590d\uff0c\u5efa\u7acb\u80a0-\u8111\u8f74\u514d\u75ab\u901a\u8baf\u7a97\u53e3\u3002\u57fa\u4e8e\u201c\u8eaf\u4f53\u611f\u89c9-\u81ea\u4e3b\u795e\u7ecf\u53cd\u5c04\u201d\u7814\u53d1\u7684\u201c\u7535\u5b50\u836f\u201d\u8bbe\u5907\uff0c\u6b63\u63a8\u52a8\u9488\u523a\u4ece\u7ecf\u9a8c\u64cd\u4f5c\u5411\u7cbe\u51c6\u795e\u7ecf\u8c03\u63a7\u53d1\u5c55\u8dc3\u8fc1\u3002\u672a\u6765\u9700\u6574\u5408\u591a\u7ec4\u5b66\u4e0e\u667a\u80fd\u7b97\u6cd5\uff0c\u6784\u5efa\u201c\u673a\u68b0\u523a\u6fc0-\u795e\u7ecf\u7f16\u7801-\u514d\u75ab\u5e94\u7b54\u201d\u6a21\u5f0f\u56fe\u8c31\uff0c\u5c06\u4e2d\u533b\u201c\u6cbb\u75c5\u6c42\u672c\u201d\u7684\u6838\u5fc3\u7406\u5ff5\u5177\u8c61\u5316\u4e3a\u5e94\u5bf9\u708e\u6027\u53cd\u5e94\u53ca\u514d\u75ab\u76f8\u5173\u75be\u75c5\u7684\u9776\u5411\u6027\u795e\u7ecf\u73af\u8def\u5e72\u9884\u65b9\u6848\u3002.",
"40409744": "ID: 40409744\nTitle: Macropinocytosis and Fast Endophilin-Mediated Endocytosis Mediate Absorption of Garlic Chive-Derived Vesicle-like Nanoparticles in Human Intestinal Epithelial Cells.\nAbstract: Dietary extracellular vesicles (EVs) or vesicle-like nanoparticles (VLNs) have been shown to exert beneficial functions in a wide range of diseases such as cancer, colitis, and metabolic diseases. They have also been used as natural carriers for medications. Despite the promising translational potential of dietary EVs or VLNs, the molecular mechanisms of their absorption in the gastrointestinal tract are not well understood. In this study, we investigated the absorption mechanisms of garlic chive-derived VLNs (GC-VLNs) using C57BL/6J mice and a human intestinal epithelial cell line, Caco-2 cells. We found that orally administered GC-VLNs crossed the epithelial layer of the small intestine and entered the underlying lamina propria. GC-VLNs were taken up and transported across the fully differentiated Caco-2 epithelial monolayer. Proteins and lipids, but not RNAs, in GC-VLNs mediated their uptake by Caco-2 cells. Chemical inhibitor treatments demonstrated that macropinocytosis and fast endophilin-mediated endocytosis (FEME) played key roles in the internalization of GC-VLNs. On the other hand, clathrin-coated pit-mediated endocytosis and clathrin-independent carrier/glycosylphosphatidylinositol-anchored protein-enriched early endocytic compartment endocytosis did not contribute to GC-VLN uptake. Activation of macropinocytosis and FEME using their specific activators promoted the internalization of GC-VLNs. In addition, genetic manipulation of key molecules in macropinocytosis and FEME confirmed the important engagement of these two specific endocytic pathways in GC-VLN absorption by human intestinal epithelial cells. Our study has provided proof-of-principle evidence to advance our understanding of the absorption mechanism of GC-VLNs, which would be the key to further manipulation and engineering of these nanoparticles to improve their delivery efficiency as therapeutic modalities or drug carriers.",
"40547857": "ID: 40547857\nTitle: Understanding mechanisms of Polygonatum sibiricum-derived exosome-like nanoparticles against breast cancer through an integrated metabolomics and network pharmacology analysis.\nAbstract: Polygonatum sibiricum has a long history of medicinal and edible usages, and has attracted widespread attention from researchers due to its rich pharmacological activities. Research has found that plant-derived exosome-like nanoparticles (PELNs) have enormous potential in the field of biomedicine, such as serving as natural nanomedicines to treat diseases or as carriers for drug delivery. However, there are no studies on P. sibiricum-derived exosome-like nanoparticles (PSELNs) against cancer. This work used ultracentrifugation to extract the PSELNs and characterized them using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and dynamic light scattering (DLS). Proteomics and metabolomics were used to analyze the components of the PSELNs, and the Herb database was used to screen for active metabolites. The OMIM and TTD databases were used to analyze active metabolites, and we further speculated that they may have anti-breast cancer (BC) activity. Network pharmacology was used to analyze the possible mechanisms of the PSELNs against BC, mainly including protein-protein interaction (PPI) network analysis for potential targets, gene ontology (GO) for analyzing biological processes, and Kyoto Encyclopedia of Genes and Genomes (KEGG) for analyzing related signaling pathways. After that, the related data of BC was retrieved from the GEO database, and the clinical expression and survival prognosis of the key genes screened by network pharmacology were analyzed by bioinformatics. Molecular docking and Molecular dynamics (MD) simulation were used to verify the binding of active metabolites in the PSELNs with their targets. Finally, the CCK-8 method was used to validate the inhibitory effect of the PSELNs on BC. Firstly, TEM, NTA, and DLS confirmed that the PSELNs were successfully isolated. Then, Proteomics identified 18 protein components from the PSELNs, including ATP synthase subunit alpha, protein Ycf2, and Mannose/silica acid binding lectin. Metabolomics identified 357 metabolic components from the PSELNs and further screened 23 active metabolites by oral bioavailability (OB), including Sedanolide, Baicalein, and 6-Gingerol, etc. By analyzing 23 active metabolites, it was speculated that the PSELNs may have pharmacological activity against BC. After that, network pharmacology was used to screen 23 key targets of the PSELNs against BC. KEGG and GO enrichment analysis showed that the MAPK signaling pathway, PI3k-Akt signaling pathway, and AMPK signaling pathway were involved in the anti-BC effect of the PSELNs. Through bioinformatics analysis of 23 key targets in BC clinical samples, it was found that, except for ESR1, which was significantly upregulated, CAV1, FGF2, and PPARG were all significantly downregulated. The expression levels of 4 targets were positively correlated with survival status. These 4 targets were validated by molecular docking and MD simulation with active metabolites in the PSELNs, and it was found that the binding of sedanolide and ESR1, Baicalein and PPARG, and 6-Gingerol and ESR1 can remain stable. Finally, The inhibitory effect of the PSELNs on BC cells (MDA-MB-231) was validated by the CCK-8 method. This was the first time that the PSELNs have been studied against cancer. It was verified that they have anti-BC activity, and the mechanism may be related to targets such as ESR1 and PPARG, regulated by active metabolites in the PSELNs. This work laid a foundation and reference for more follow-up related research studies.",

Side effects and drug resistance limit current therapies. Andrographolide (AG), an NF-\u03baB pathway inhibitor, shows promise in UC treatment but suffers from poor oral bioavailability. In this study, Paederia scandens-derived exosome-like nanoparticles (P-ELNs) were used as a delivery system to enhance the therapeutic efficacy of AG in UC. P-ELNs were extracted from Paederia scandens leaves and characterized for size, zeta potential, and morphology using transmission electron microscopy (TEM) and nanoparticle tracking analysis. AG was loaded into P-ELNs (AG-P-ELNs), and the complex was characterized for encapsulation efficiency using high-performance liquid chromatography (HPLC). The anti-inflammatory effects of AG, P-ELN, and the AG-P-ELNs complex were assessed in LPS-stimulated RAW264.7 macrophages (in vitro) and in a dextran sulphate sodium (DSS)-induced colitis mouse model (in vivo). According to the results, AG-P-ELNs demonstrated a high encapsulation efficiency of 38.64\u00a0% and a stable dispersion system with a zeta potential of -38.55\u00a0mV, indicating good colloidal stability. In vitro, AG-P-ELNs significantly reduced the production of pro-inflammatory cytokines IL-1\u03b2, IL-6, IL-18 and TNF-\u03b1, promoting M1 macrophage polarized to M2. In vivo, AG-P-ELN treatment ameliorated DSS-induced colitis, normalized colon length, and mitigated inflammatory cell infiltration. The AG-P-ELN group showed the lowest NF-\u03baB, NLRP3, and iNOS expression, suggesting a synergistic therapeutic effect in modulating macrophage polarization and inflammation. P-ELNs effectively enhance the bioavailability and therapeutic efficacy of AG in treating UC by improving its solubility, stability, and cellular uptake while modulating macrophage polarization and inflammation. This study provides a novel approach for the delivery of AG and highlights the potential of plant-derived nanoparticles in inflammatory bowel disease management.",

Its neuroprotective properties have been documented in conditions involving neurological exhaustion and immune dysregulation. This study investigated the therapeutic potential and mechanisms of ginsenoside Rg1 in mitigating neurobehavioral and systemic immune dysfunction induced by prolonged general anesthesia. Mice exposed to 6\u00a0h of isoflurane anesthesia received ginsenoside Rg1 (10\u00a0mg/kg, i.p.) every 24\u00a0h for three doses. Neurobehavioral outcomes were assessed using Y-maze and open field tests. Hippocampal synaptic function (mIPSCs), systemic inflammation (IL-6, TNF-\u03b1), gut barrier integrity (FITC-dextran assay), and colonic regulatory T cell (Treg) populations were quantified. Treg dependency was validated using DEREG mice with diphtheria toxin-mediated ablation. Mice exposed to prolonged isoflurane anesthesia exhibited anxiety-like behaviors, cognitive deficits, elevated IL-6 and TNF-\u03b1 levels in the hippocampus and bloodstream, impaired synaptic transmission, increased intestinal permeability, and reduced regulatory T cells, indicative of gut-immune-brain axis disruption. Treatment with Ginsenoside Rg1 effectively reversed these deficits by improving behavior, reducing inflammation, restoring synaptic function, and preserving gut-immune integrity. Crucially, Treg ablation in DEREG mice abolished Rg1's benefits, while Treg levels correlated with cognitive improvement. Ginsenoside Rg1 ameliorates anesthesia-induced neuroimmune dysfunction through Treg-mediated gut-immune-brain axis restoration, offering a novel therapeutic strategy for postoperative neurological complications.",

Ginsenoside Rb3 (Rb3) is known to exhibit protective effects against myocardial ischemia, its impact on CIRI remains unclear. Therefore, we investigated the protective effects of Rb3 on CIRI and its underlying mechanisms. Our results showed that Rb3 reduced cerebral infarct volume, decreased blood-brain barrier (BBB) permeability, and improved neurological deficits in CIRI rats. Rb3 also mitigated cerebral ferroptosis and alleviated neuroinflammation, as evidenced by decreased iron levels, reduced MDA content, an improved GSH/GSSG ratio, and lower levels of TNF-\u03b1, IL-1\u03b2, and IL-6, through modulation of the NLRP3/NF-\u03baB/GPX4 pathway. Additionally, Rb3 alleviated intestinal inflammation, improved the intestinal barrier, and corrected gut microbiota dysbiosis and reduced the microbial metabolites TMAO and LPS in CIRI rats. It is noteworthy that in pseudo germ-free rats with CIRI, fecal microbiota transplants (FMT) from Rb3-treated rats conferred similar protective effects as Rb3. Summarily, this study reveals that Rb3 reduces neuroinflammation and ferroptosis in the brains of middle cerebral artery occlusion/reperfusion (MCAO/R) rats via the NLRP3/NF-\u03baB/GPX4 pathway in a gut microbiota-dependent manner.",

Ginsenoside Rk3 (Rk3), a rare ginseng saponin, possesses anti-inflammatory and microbiota-modulating properties. However, its role in the regulation of the gut-brain axis remains unclear. In this study, the key gut microbial species and microbial metabolites associated with the PD-protective effects of Rk3 was explored using rotenone-induced PD mouse model through behavioral experiments, multiomics analysis and targeted bacteria/metabolites supplementation. Rk3 could restore the intestinal microbial homeostasis by enriching Lactobacillus murinus and Clostridium, and delay PD progression by lightening neuroinflammation in a gut microbiota-dependent manner. Crucially, Rk3 significantly increased levels of microbial metabolite butyrate, which could protect dopaminergic neurons and mitigate neuroinflammation by inhibiting histone deacetylase (HDAC) activity and activating the JAK/STAT3 signaling pathway. Overall, Rk3 delays PD progression via intestinal microbial homeostasis remodeling, highlighting its therapeutic potential for neurodegenerative disorders mediated by the gut-brain axis.",

Current antidiabetic therapies offer only partial glycemic control and are limited by poor bioavailability, adverse effects, and an inability to prevent disease progression. Plant-derived exosome-like nanoparticles (PENPs) have emerged as a promising class of natural nanocarriers with excellent biocompatibility, low immunogenicity, and intrinsic multi-component bioactivity. However, few reviews have addressed recent progress in PENPs for DM therapy. To capture the recent developments in this area, this review provides a systematic synthesis of recent advances in PENPs for DM therapy, covering plant sources, extraction and purification methods, molecular compositions, and therapeutic mechanisms. Preclinical studies have demonstrated that PENPs can improve hyperglycemia, enhance insulin sensitivity, regulate hepatic lipid metabolism, and promote wound healing by modulating oxidative stress, inflammation, gut microbiota, glucose metabolism, and insulin signaling. Additionally, PENPs have been shown to promote angiogenesis via glycolytic reprogramming. Despite these promising findings, challenges including scalable isolation, standardized physicochemical characterization, and clinical translation remain. Future directions include engineering multifunctional PENPs, establishing Good Manufacturing Practice (GMP)-compliant production, and conducting clinical trials to facilitate their integration into precision therapeutics for diabetes management.",
"41024269": "ID: 41024269\nTitle: Effects of exercise on neuroinflammation in age-related neurodegenerative disorders.\nAbstract: Neuroinflammation plays a critical role in the pathogenesis of aging-related neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, and Multiple Sclerosis. It involves the activation of glial cells and the release of pro-inflammatory mediators and reactive oxygen and nitrogen species, which, when chronically sustained, contribute to neuronal damage and cognitive decline. Recent evidence suggests that regular physical exercise exerts neuroprotective effects by modulating neuroinflammatory pathways and enhancing brain health. Exercise has been shown to regulate the activity of microglia and astrocytes, strengthen the blood-brain barrier, and reduce systemic and gut-derived inflammation-all of which are implicated in the progression of neurodegeneration. Additionally, exercise influences inflammasome signaling, a key component in the innate immune response, further mitigating inflammation-induced neuronal injury. This review summarizes current findings on the impact of physical activity on inflammation and inflammasome pathways in aging-related neurodegenerative diseases, highlighting the therapeutic potential of exercise as a non-pharmacological intervention. Further research is warranted to optimize exercise protocols for maximal neuroprotective benefits.",

This study demonstrates that resveratrol (RSV), a natural polyphenol, alleviates DSS-induced colitis-associated anxiety and depression by reprogramming the microbiota\u2500metabolite-barrier network. RSV (100 mg/kg/day) ameliorated DSS-associated anxiety-like behaviors in open field tests (peripheral zone time \u219312.6%, P< 0.0001) and depression-like phenotypes (TST immobility \u219331.0%, P = 0.0004). It restored colonic barrier integrity via ZO-1 mRNA upregulation (\u219180.4%, P < 0.0001) and PAS score recovery (\u219129.6%, P < 0.0001), while reducing systemic inflammation (serum LPS \u219331.9%, TNF-\u03b1 \u219329.9%; P < 0.0001) vs. DSS. Crucially, RSV attenuated neuroinflammation by enhancing brain ZO-1 protein expression (\u2191146.1%, P = 0.0016), suppressing TLR4/MyD88/NF-\u03baB signaling (TLR4 mRNA \u219368.8%, MyD88 protein \u219348.8%; P < 0.05), and promoting M2 microglial polarization (CD206 protein \u2191171.9%, P = 0.0003) vs. DSS. Multi-omics integration revealed RSV\u2019s dual regulatory mechanism: \u2460 Suppression of the pro-inflammatory Turicibacter4-guanidinobutanoic acid axis (\u219342% and \u219337%, respectively; P < 0.01), disrupting LPS\u2500TLR4\u2500MyD88 cascades; \u2461 Enrichment of barrier-protective Muribaculum (\u2191419%) and Dubosiella (\u2191208%), driving polyamine synthesis (spermidine \u219192%, spermine \u219138%) vs. DSS to reinforce gut-brain barriers.

Xinqingning Tablet (XQNT) demonstrates neuroprotective potential in IS complicated by gut dysbiosis (GD), yet its mechanisms of GBA modulation remain unclear. A dual-hit IS-GD mouse model was established via fecal slurry transplantation and permanent middle cerebral artery occlusion (pMCAO) surgery. Gut function was evaluated by constipation indices and histopathological changes, while the neuroprotective efficacy of XQNT (0.36, 0.48, and 0.61 g kg\u207b\u00b9) was assessed via TTC staining, neurological deficit scores, cerebral water content, and Evans blue (EB) extravasation assays. Additionally, Western blot was employed to quantify blood-brain barrier (BBB) and inflammation-associated proteins. microRNA sequencing was used to screen the differentially expressed miRNAs. miR-126 expression levels were measured by RT-qPCR, while concentrations of LPS, IL-6 and IL-10 were determined by ELISA. Finally, mechanistic validation employed intravenous miR-126 agonism/antagonism coupled with phenotypic rescue experiments. XQNT conferred robust survival benefits, while concurrently ameliorating intestinal dysfunction and neurovascular injury. Mechanistically, XQNT elevated miR-126 expression, suppressing NF-\u03baB-driven neuroinflammation. Additionally, miR-126 agonism phenocopied XQNT efficacy, whereas miR-126 inhibition abrogated therapeutic benefits. This study provides early evidence that XQNT functions as a dual-target GBA modulator that alleviates IS with GD via regulation of the miR-126/NF-\u03baB axis. By simultaneously promoting barrier restoration and inflammatory resolution, XQNT offers a promising therapeutic approach that links regulation of the gastrointestinal system with cerebrovascular protection.",

Inflammatory processes in the central nervous system can exacerbate these diseases by causing neuronal damage and apoptosis. Traditional Chinese medicines have become an important area of research in anti-neuroinflammation and neuroprotection owing to their multi-target effects and favorable safety profiles. In this paper, we review the molecular mechanisms by which bioactive compounds of herbal origin inhibit neuroinflammation and improve disease progression through the modulation of inflammatory factors (including TLR4/MyD88/NF-\u03baB, NLRP3 inflammasomes, and Janus kinase-STAT signaling), epigenetic modifications, cell-type-specific modulation (microglia M1/M2 polarization and astrocyte A1/A2 transformation), and gut-brain axis interactions. These bioactive compounds are mainly classified into those with well-defined chemical structures (such as baicalein, baicalin, berberine, and ginsenoside Rg1), plant extracts (such as tonifying Yang Huiwu Tang, Tongxinluo capsule, Shu Xuning injection, and Xingxiong injection), and preparations based on special mechanisms of action or technical means (such as Hedysari polysaccharides [RHP] and microglial cell exosome carrier berberine and palmatine [Exos-Ber/Pal]). We found that these compounds can improve cognitive and motor dysfunction by inhibiting neuroinflammation while exerting neuronal protection, but their low bioavailability, mechanistic complexity, and lack of clinical translational evidence remain challenges. In the future, a combination of multi-omics techniques, rigorously designed clinical trials, and interdisciplinary strategies will be required to promote the precise application of herbal medicines in neuroinflammation-related diseases.",

This systematic review aims to examine the current evidence on the association between malnutrition and IP, identifying existing research gaps. A systematic search was conducted on PubMed, Scopus and Web of Science up to June 2024. According to PECOS strategy, \u2018P\u2019 = malnourished individuals or at risk of malnutrition, assessed for intestinal permeability; \u2018E\u2019 = malnutrition or risk of malnutrition; \u2018C\u2019 = well-nourished individuals; \u2018O\u2019 = increased intestinal permeability; and \u2018S\u2019 = all study types.

Sixteen studies met the inclusion criteria, with a moderate/high risk of bias. Malnourished individuals exhibited increased IP across various conditions (e.g. anorexia nervosa, cancer and liver cirrhosis) or setting (hospital and community). A wide heterogeneity was observed in malnutrition assessment tools, which consider different parameters such as body mass index, body weight loss and food intake. Similarly, diverse biomarkers/methods for assessing IP, including direct and indirect approaches, were used.

Although Tuina has shown neuroprotective effects, it remains unclear whether these benefits involve regulation of the gut-brain axis. This study aimed to evaluate the therapeutic effects of Tuina in CP rats, with emphasis on its potential regulation of the gut-brain axis. CP was induced in 7-day-old Sprague-Dawley rats through hypoxia-ischemia. Beginning on postnatal day 8 (P8), the Tuina group received daily Tuina therapy for 32 consecutive days. Motor function was assessed using the negative geotaxis test (P6-P12), the beam balance test (P36-P39), and the modified neurological severity score on P40. Gut microbiota composition was analyzed\u00a0using 16S rRNA sequencing. Brain and intestinal histopathology were evaluated histologically via hematoxylin-eosin and Luxol fast blue staining. Protein expression of BDNF, Nrf2, GPX4, ZO-1, and occludin was assessed via western blotting and immunofluorescence. Serum short-chain fatty acids (SCFAs) were measured by mass spectrometry, whereas oxidative stress and intestinal barrier markers (superoxide dismutase, malondialdehyde, glutathione peroxidase, lipopolysaccharide [LPS], diamine oxidase [DAO], and D-lactate [D-LA]) were detected using enzyme-linked immunosorbent assay. In CP models induced by hypoxic-ischemic encephalopathy, significant brain injury and motor dysfunction were observed, accompanied by gut microbiota dysbiosis and impaired intestinal barrier function. Tuina intervention improved motor function and growth, regulated gut microbiota, and increased serum SCFA levels. It also enhanced intestinal barrier proteins (occludin, ZO-1), reduced serum levels of LPS, DAO, and D-LA, and increased the expression of brain-derived BDNF, Nrf2, and GPX4. Tuina significantly alleviated brain injury and improved motor function in CP rats. These effects were associated with modulation of the gut microbiota and restoration of intestinal barrier integrity, suggesting that the gut-brain axis may mediate the neuroprotective effects of Tuina.",

Growing evidence indicates that a healthy gut microbiota (GM) is essential for regulating redox homeostasis, whereas gut dysbiosis contributes to elevated ROS levels and oxidative damage in DNA, lipids, and proteins. This redox disequilibrium initiates a cascade of cellular disturbances-including synaptic dysfunction, altered receptor activity, excitotoxicity, mitochondrial disruption, and chronic neuroinflammation-that can, in turn, impair cognitive and social functioning in metabolic and neuropsychiatric disorders via epigenetic mechanisms. In this review, we synthesize current knowledge on (1) how OS contributes to cognitive and social deficits through epigenetic dysregulation; (2) the role of disrupted one-carbon metabolism in epigenetically mediated neurological dysfunction; and (3) mechanistic links between leaky gut, OS, altered GM composition, and GM-derived epigenetic metabolites. We also highlight emerging microbiota-based therapeutic strategies capable of mitigating epigenetic abnormalities and improving cognitive and social outcomes. Understanding the OS-microbiota-epigenetic interplay may uncover new targetable pathways for therapies aimed at restoring brain and behavioral health.",
"41530574": "ID: 41530574\nTitle: The gut-kidney axis in pediatric acute kidney injury: a review of pathophysiological mechanisms and therapeutic frontiers.\nAbstract: Acute kidney injury (AKI) is a frequent and severe condition in hospitalized children, leading to significant morbidity, mortality, and long-term risk of chronic kidney disease. This review explores the gut-kidney axis, a concept describing the bidirectional relationship between the gut microbiome and kidney function, as a critical driver of pediatric AKI. In critically ill children, interventions such as broad-spectrum antibiotics and necessary nutritional support strategies (e.g., parenteral nutrition or fasting) can cause profound gut microbial imbalance (dysbiosis). This dysbiosis initiates a deleterious feedback loop, exacerbating kidney injury. Key mechanisms include the disruption of the intestinal barrier (leaky gut), which allows bacterial endotoxins to enter the bloodstream, triggering renal inflammation via Toll-like receptor 4 signaling. Concurrently, the dysbiotic gut increases production of directly nephrotoxic gut-derived uremic toxins, such as indoxyl sulfate and p-cresyl sulfate, while failing to produce protective anti-inflammatory metabolites like short-chain fatty acids. While therapies targeting the microbiome, such as probiotics, prebiotics, and fecal microbiota transplantation, are theoretically promising, their clinical use in pediatric AKI is unsupported by evidence and carries substantial risks, particularly iatrogenic infection. A significant knowledge gap exists due to a relative lack of pediatric-specific clinical research. The conclusion emphasizes an urgent need for longitudinal, multi-omics studies in children to understand this axis, identify functional biomarkers, and develop safe, targeted therapies to improve outcomes.",

The gut microbiome may contribute to these pathways via leaky gut and immune\u2013metabolic processes. To identify gut microbial alterations in MDD and to quantify functional pathways and enzyme gene families and integrate these with the clinical phenome and immune\u2013metabolic biomarkers of MDD. Shotgun metagenomics with taxonomic profiling was performed in MDD versus controls using MetaPhlAn v4.0.6, and functional profiling was conducted using HUMAnN v3.9, aligning microbial reads to species-specific pangenomes (Bowtie2 v2.5.4) followed by alignment to the UniRef90 v201901 protein database (DIAMOND v2.1.9). Gut microbiome diversity, both species richness and evenness, is quite similar between MDD and controls. The top enriched taxa in the multivariate discriminant profile of MDD reflect gut dysbiosis associated with leaky gut and NIMETOX mechanisms, that is, Ruminococcus gnavus, Veillonella rogosaem, and Anaerobutyricum hallii. The top four protective taxa enriched in controls indicate an anti-inflammatory ecosystem and microbiome resilience, that is, Vescimonas coprocola, Coprococcus, Faecalibacterium prausnitzii, and Faecalibacterium parasitized. Pathway analysis indicates loss of barrier protection, antioxidants, and short-chain fatty acids, and activation of NIMETOX pathways. The differential abundance of gene families suggests that there are metabolic distinctions between both groups, indicating aberrations in purine, sugar, and protein metabolism. The gene and pathway scores explain a larger part of the variance in suicidal ideation, recurrence of illness, neurocognitive impairments, immune functions, and atherogenicity. The gut microbiome changes might contribute to activated peripheral NIMETOX pathways in MDD.",
"41663400": "ID: 41663400\nTitle: Phytic acid (InsP6) activates HDAC3 epigenetic axis to maintain intestinal barrier function.\nAbstract: HDAC inhibition shows promise in cancer treatment but pan-HDAC inhibitors cause gastrointestinal issues in 48% of patients. Understanding HDAC activation mechanisms is crucial to treating diverse diseases beyond cancer. Our study reveals that inositol polyphosphate multikinase (IPMK) and inositol hexakisphosphate (InsP6 or phytic acid), enriched in vegan diets, play essential roles in activating the HDAC3 epigenetic axis and maintaining intestinal barrier integrity. IPMK binds to HDAC3 and drives InsP6 synthesis, which selectively activates HDAC3 at a 10\u2009nM concentration by recruiting the DAD domain of its corepressor protein. IPMK deletion diminishes HDAC3 activation, leading to histone hyperacetylation and MMP gene transcription that compromise intestinal barrier integrity. InsP6 treatment is sufficient to rescue these effects. In inflammatory bowel disease, diminished IPMK levels exacerbate intestinal permeability, while oral InsP6 treatment mitigates leaky gut effects by restoring the HDAC3 epigenetic axis, highlighting the clinical significance of the IPMK-HDAC3 pathway and the therapeutic potential of phytic acid.",
"41703973": "ID: 41703973\nTitle: Impaired Intestinal Function Among Indigenous Shuar Children of Amazonian Ecuador: Evidence From Lactulose:Mannitol Tests of Absorption and Permeability.\nAbstract: Intestinal function is an important but often overlooked aspect of human biological variation, with the intestines serving as both a barrier against external pathogens/contaminants and the primary conduit of nutrient extraction from food. Impaired intestinal function among children is viewed as a key contributor to growth faltering globally. However, few studies have investigated children's intestinal function in rural settings or beyond infancy. To address this limitation, we conducted a pilot study to describe the intestinal function of school-age Indigenous Shuar children of Amazonian Ecuador and to assess the feasibility of implementing the widely utilized lactulose:mannitol (L:M) test of absorption and permeability with this group. The urinary L:M test was performed with 23 rural-living Shuar children aged 4-12\u2009years. Ultra-performance liquid chromatograph-high-resolution mass spectrometry was used to determine L:M ratios, lactulose recovery, and mannitol recovery. Age and sex patterns were investigated using linear regression models. Children's mean L:M ratio was 0.33\u2009\u00b1\u20090.32, a ratio comparable to values reported for children in other low- and middle-income settings. 35%-91% of children were categorized as having impaired intestinal function using common cut-off values. Children's lactulose (0.14%\u2009\u00b1\u20090.17%) and mannitol (2.60%\u2009\u00b1\u20092.22%) recoveries did not differ by sex but increased with age (p\u2009<\u20090.05) and indicated diminished intestinal absorptive capacity and increased permeability. Intestinal function appears to be considerably impaired among school-age Shuar children living in a low-resource, rural setting. Children living in unsanitary, non-industrialized contexts may routinely experience intestinal permeability-related immune activation and malabsorption-related energy/nutrient loss. More research is needed to explore the breadth of global variation in children's intestinal function and to investigate its many evolutionary and public health implications.",
"41828410": "ID: 41828410\nTitle: Integrated Untargeted and Targeted Metabolomics Reveals Distinct Bioactive Metabolite Profiles Between Probiotic Supplements and Yogurt.\nAbstract: Probiotics are widely consumed as health-promoting agents, with probiotic supplements (PS) and yogurt (YG) representing formulated products and fermented foods, respectively. Despite their broad consumption, systematic comparisons of their biochemical characteristics remain limited. In this study, integrated untargeted and targeted metabolomics approaches were applied to compare the comprehensive metabolite profiles of PS and YG. PS exhibited relatively higher levels of amino acids, dicarboxylic acids, and lysophospholipids, along with short-chain fatty acids such as acetate and propionate, and amino acid-derived bioactive metabolites, including \u03b3-aminobutyric acid, branched-chain hydroxy acids, indole derivatives, and \u03b3-glutamylpeptides. In contrast, YG showed higher relative abundances of carbohydrates, acylcarnitines, sphingolipids, and bioactive metabolites such as butyrate, creatine, carnitine, and orotic acid. Based on these metabolomic differences, 27 PS-specific and 17 YG-specific marker metabolites were identified. To explore their functional relevance, in vitro antioxidant and antiglycation activities were evaluated. PS exhibited significantly higher antioxidant and antiglycation activities than YG, which were positively correlated with amino acids and indole derivatives. Indole-3-acrylic acid, indole-3-acetic acid, and indole-3-propionic acid showed antiglycation activity and were identified as PS-specific bioactive marker metabolites. These findings reveal the distinct biochemical characteristics of PS and YG and highlight potential bioactive candidate metabolites that may contribute to their functional differences.",

Methods: This study conducted a nationwide survey using multi-stage stratified random sampling, including 48,305 children aged 6-17 years. Body fat percentage (BFP) was measured using bioelectrical impedance analysis (BIA). Daily yogurt consumption was adjusted using the density method (daily yogurt consumption = daily yogurt consumption \u00d7 1000/total energy consumption). The association between yogurt consumption and body fat percentage was analyzed using quantile regression, with covariates adjusted for participants' age, pubertal development stage, geographical region, total daily energy consumption, physical activity duration, annual household income, parental educational attainment, and consumption of other food categories. Results: Boys aged 6-10 years, 11-14 years, and 15-17 years had median daily yogurt consumptions of 28.6 g, 28.6 g and 21.4 g per day, with BFP values of 19.6, 19.5 and 17.5. Girls in the same age groups showed consumption of 28.6 g, 29.6 g and 28.6 g, with BFP values of 20.3, 26.4 and 31. The quantile regression results for boys showed that daily consumption of yogurt was significantly correlated with their BFP at the 0.25, 0.50, 0.75, 0.85 and 0.95 quartiles, with regression coefficients of -0.207, -0.300, -0.688, -0.570, and -0.465 after adjusting for potential confounders. For girls, there was a significant correlation in the 0.75 and 0.85 quartiles, with regression coefficients of -0.290 and -0.582, after adjusting for potential confounders. Conclusions: A significant inverse association was observed between yogurt consumption and body fat percentage, with notable differences between boys and girls. Further intervention studies are warranted to evaluate the long-term effects of incorporating yogurt into the diets of Chinese children and adolescents on body fat percentage and obesity risk.",

Using a simplex lattice mixture design, five samples of varying weight ratios of sorghum/baobab (17.5/32.5-47.5/2.5, w.b.) were prepared by mixing sorghum/baobab blend (50\u00a0g, w.b.), milk (500\u00a0mL), Lactobacillus bulgaricus species and Streptococcus thermophilus species, and fermenting at 40\u00b0C for 9 h. After only fermenting milk, one Control was prepared by adding sorghum/baobab (32.5/17.5). The samples were evaluated for pH, texture, LAB count, and iron solubility after simulated digestion. A total of 125 panelists, including 32 Africans, evaluated the samples flavored with bananas after fermentation, using a nine-point hedonic scale and check-all-that-apply (CATA) method. Data were analyzed using variance analysis, least significant difference test, agglomerative hierarchical clustering, and Fisher's exact test. All samples had a pH below 4.6 and a LAB count of 108, except for sample 17.5/32.5 (104), likely due to baobab's acidity hindering LAB growth. Fermenting sorghum, baobab, and milk together increased iron solubility by 64.1% compared to the Control. From the CATA results, sweet flavor and creamy mouthfeel increased overall liking, while tart flavor and gritty mouthfeel decreased liking. Cluster analysis showed that Africans favored samples with both less and more baobab equally (40/10, 25/25, overall liking of 6.8), while Caucasians preferred less baobab (40/10, overall liking of 4.8). Both clusters disfavored the Control (overall liking 6.0 and 4.1), which had the lowest instrumental texture consistency.",

This review summarizes the current clinical evidence and mechanistic insights on the role of probiotic interventions in mitigating cognitive decline and enhancing brain function, particularly in older adults and individuals with neuropsychiatric conditions. Cognitive impairments in the elderly, driven by neurodegeneration, vascular compromise, inflammation, and lifestyle factors, present significant challenges to public health systems. Several randomized controlled trials have demonstrated the beneficial effects of specific probiotic strains, such as Bifidobacterium breve A1, Lactiplantibacillus plantarum P8, and multispecies formulations, in improving memory, attention, and emotional regulation in populations with mild cognitive impairment, Alzheimer's disease, major depressive disorder, and schizophrenia. The cognitive improvements are linked to various mechanisms, including anti-inflammatory and antioxidant activities, modulation of neurotransmitter levels, maintenance of gut barrier integrity, and shifts in gut microbiota composition favoring beneficial taxa. However, not all interventions have yielded significant effects, suggesting strain-specific efficacy and interindividual variability in response. The present study discusses the limitations of existing studies and emphasizes the need for personalized approaches and rigorous, long-term clinical trials. Overall, probiotics show promise as adjunctive agents for preserving cognitive health and managing neurodegenerative and psychiatric disorders via modulation of the microbiota-GBA.",

The effect of bee pollen on starter culture bacteria (Bifidobacterium spp., L. acidophilus, L. bulgaricus, and S. thermophilus) was analyzed during fermentation (42\u00b0C, 24 hours) and storage (4\u00b0C, 14 days). The microbiological properties were determined for food safety. The addition of bee pollen decreased the pH value during fermentation. The lowest mean count was in Bifidobacterium spp. (6.94 log CFU/g), followed by L. acidophilus (7.64 log CFU/g), L. bulgaricus (8.20 log CFU/g), and S. thermophilus (8.57 log CFU/g) at the end of fermentation. The pH values were decreased in all samples during storage. The viability of L. acidophilus and Bifidobacterium spp. was lower than 6 log CFU/g on the 14th day. L. acidophilus was 5.83 log CFU/g and 5.98 log CFU/g in control and yogurts with 0.5% bee pollen. Bifidobacterium spp. counts were 5.72 log CFU/g, 5.35 log CFU/g, and 5.27 log CFU/g in yogurts with 1.5%, 3%, and 6% bee pollen, respectively.

Here, a binary yogurt fermentation model comprising Levilactobacillus brevis 54 and Lacticaseibacillus casei 56 was employed to elucidate how externally supplied autoinducing peptides (AIP) and autoinducer-2 (AI-2) reprogram microbial behavior and flavor-associated metabolism. Targeted supplementation with strain-specific AIP (AGQYYINHR and AYFQT) significantly enhanced bacterial growth, with elevated viable cell counts closely associated with accelerated casein hydrolysis and increased accumulation of AA-derived metabolites. In parallel, exogenous AI-2 (24 \u03bcM) stimulated bacterial growth and activated the AI-2/LuxS signaling cascade, accompanied by increased transcription of luxS, plnB, and plnC. Metabolomic analyses revealed that AIP primarily modulated AA metabolic pathways, whereas AI-2 exerted broader regulatory effects spanning AA, carbohydrate, and central carbon metabolism, partly mediated through upregulation of the AI-2-associated enzyme MtnN. Integrated profiling of nonvolatile and volatile flavor compounds demonstrated that coordinated AIP- and AI-2-mediated signaling redirected metabolic fluxes toward flavor-active derivatives, leading to enhanced formation of alcohols, ketones, and organic acids that contribute to yogurt aroma. Collectively, this study delineates how parallel intraspecies and interspecies quorum-sensing pathways integrate to reshape metabolic networks during yogurt fermentation, providing mechanistic insight into signal-driven flavor modulation and a framework for the rational design of flavor-enhanced fermented dairy systems.",

The starter cultures Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus were exposed to X-ray radiation using Xstrahl 320 medical irradiator with an energy of 150-320\u2009keV with a dose rate of 1.67\u2009cGy/s. The starter cultures were exposed to 60-120\u2009cGy radiation before fermentation and evaluation of their physicochemical properties during 14-day storage. The results showed that exposure of the starter culture to 60\u2009cGy, 80\u2009cGy, and 120\u2009cGy delayed yogurt fermentation by 6.5, 6, and 6\u2009hours, respectively, in comparison with the control yogurt (5.5\u2009h). The starter culture irradiated at 60\u2009cGy showed the lowest acidification rate and reduced post-acidification during refrigerated storage. This reduced acidification rate limited pH drift after fermentation, resulting in a more relaxed casein network and reduced syneresis. In contrast, higher irradiation doses (80 and 120\u2009cGy) selected metabolically robust cells capable of sustained acid production during storage. The pH of all the yogurt samples decreased slightly during storage, but not enough to weaken or destabilize the electrostatic interaction between the casein networks. Total viable bacterial counts decreased in all yogurt samples, with the 80\u2009cGy sample showing the lowest viability during storage. Irradiation increased fermentation time and decreased viability of the starter culture while simultaneously improving post-acidification and syneresis during storage. However, changes to the physicochemical properties of the yogurt samples were not significant enough to cause any negative impact on yogurt quality.",

The resulting microcapsules were incorporated into water, yogurt, and gelatin to develop carotenoid-fortified foods. The effects of wall material and matrix on carotenoid bioaccessibility during in vitro digestion and their contribution to the recommended dietary allowance (RDA) across age groups were assessed. Carotenoid content and bioaccessibility varied significantly with encapsulant type and matrix. The combination of ultrasound-modified and dual-modified starch improved carotenoid bioaccessibility up to 27% (20\u00a0mg/100\u00a0g) in water, 16% (27\u00a0mg/100\u00a0g) in gelatin and 8% (49\u00a0mg/100\u00a0g) in yogurt; providing enhanced encapsulation and stability. Yogurt yielded the highest bioaccessibility, likely due to lipid-protein interactions enhancing carotenoid stability under gastrointestinal conditions. A 200\u00a0mL serving of fortified yogurt could provide 26%-36% of adult and 39%-62% of child (ages 4-13) vitamin A RDA.

Milk proteins (sodium caseinate [NaCas], milk protein concentrate [MPC], and whey protein isolate [WPI]) were used to replace the protein in skim milk powder (SMP) at ratios of 10%, 20%, and 40% (w/w). Stabilizers (pectin, gelatin, and soluble soybeanpolysaccharide [SSPS]) were added post-fermentation, and their concentrations in the final yogurt were 0.2%, 0.4%, and 0.4% (w/w), respectively. Milk was heated under different conditions (75\u00b0C/20\u00a0min [75-Y], 85\u00b0C/15\u00a0min [85-Y], and 95\u00b0C/5\u00a0min [95-Y]). Replacing SMP WPI, especially at 40%, yielded smaller particle sizes and higher water-holding capacity (WHC), whereas MPC or NaCas increased particle size. All stabilizers enlarged particles, with pectin exhibiting the most pronounced effect due to bridging flocculation. Heat treatment at 85\u00b0C produced the smallest particle size and highest WHC, whereas 95\u00b0C and 75\u00b0C treatments resulted in larger particles and reduced WHC. Higher protein substitution levels generally reduced viscosity, with 40% WPI significantly reducing viscosity. Conversely, pectin addition generated the highest viscosity, and SSPS the least. The high viscosity of 75-Y corresponded to its larger particles and lower WHC. Tribological analysis indicated that increasing the proportion of protein substitutes reduced the coefficient of friction, and notably, a 40% WPI substitution significantly improved lubrication properties associated with the creaminess sensation. Pectin also induced a rapid friction drop, consistent with its high viscosity. Although friction curves were similar across heat treatment, the friction coefficients of 75-Y and 95-Y were lower than that of 85-Y at medium sliding speeds.",

Emerging evidence suggests the gut microbiota is involved in its pathogenesis. This study aimed to determine whether acupoint catgut embedding (ACE) could alleviate POCD by modulating the gut microbiota in aged mice after laparotomy. Eighteen-month-old male C57BL/6J mice underwent laparotomy on day 8 (excluding the Sham group). The ACE group received ACE treatment, while the anesthesia and surgery group served as surgical controls. The fecal microbiota transplantation (FMT)-ACE and FMT-AS groups received FMT from corresponding donors. Additional groups received oral indole-3-propionic acid (IPA) or vehicle-treated surgery. Hippocampal inflammation and blood-brain barrier proteins were assessed on day 9; cognitive function and intestinal markers on day 15. Cognitive function was significantly improved in the ACE, FMT-ACE, and IPA groups. ACE and FMT-ACE treatments specifically elevated fecal g-Clostridia_UCG-014 abundance and serum IPA levels. These changes were accompanied by suppressed hippocampal toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-\u03baB) signaling and proinflammatory cytokines [tumor necrosis factor alpha, interleukin (IL)-1\u03b2], together with elevated tight junction proteins (occludin, claudin-5). Furthermore, colonic aryl hydrocarbon receptor (AhR) and IL-22 were upregulated, while serum lipopolysaccharide and diamine oxidase were reduced. Accordingly, IPA treatment mirrored the key anti-inflammatory and barrier-protective effects. ACE alleviates POCD probably by modulating gut microbiota, specifically increasing g-Clostridia_UCG-014 abundance and metabolite IPA. These effects are potentially mediated by dual pathways: (a) suppression of neuroinflammation via TLR4/NF-\u03baB signaling, and (b) enhancement of gut barrier integrity via AhR/IL-22 axis. Our findings highlight the therapeutic potential of ACE in targeting the gut-brain axis for POCD management.",
"41874395": "ID: 41874395\nTitle: Dysbiosis and the gut-brain axis impairment in the pathophysiology of Alzheimer's disease and related dementias: is 'pathobiome' an etiological element?\nAbstract: The gut microbiome plays a pivotal role in host metabolic, cardiovascular, and immune health. Increasing evidence also links it to aging-associated neurocognitive decline and neurodegenerative disorders, including Alzheimer's disease (AD) and related dementias. While the precise mechanisms of the gut-microbiome-brain axis remain incompletely understood, recent findings challenge the traditional view of AD as a disease confined to the central nervous system. Aging-associated gut dysbiosis, marked by loss of beneficial microbes, expansion of opportunistic pathogens, and reduced microbial diversity, can compromise intestinal barrier integrity, leading to 'leaky gut' and increased translocation of microbial components or pathogens into the circulation. These elements may cross a weakened blood-brain barrier, triggering neuroinflammation, amyloid-beta accumulation, tau hyperphosphorylation, and neuronal injury. Such pathobiome-driven inflammatory cascades may initiate or accelerate AD pathology, shifting the etiological perspective beyond the amyloid and tau hypotheses toward systemic and peripheral contributors. Our work and others' have identified distinct dysbiotic microbiome signatures in AD, supporting the possibility that AD pathogenesis may begin in the gut. Restoring microbial homeostasis through targeted interventions could attenuate neuroinflammatory and neurodegenerative processes, offering a novel preventive and therapeutic avenue. This emerging paradigm underscores the need for comprehensive, mechanistic, and longitudinal studies to define how aging-driven microbiome alterations influence the gut-brain axis and contribute to AD progression.",

Twenty-four aged male rats were divided into four groups: control, omega-3, PPA and PPA + omega-3. Serum cytokines, tight-junction proteins (TJP1), dopamine, serotonin, short-chain fatty acids (SCFAs), oxidative stress markers, and histopathology of the brain and small intestine were evaluated. PPA exposure significantly increased tumour necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-6 (IL-6) and reduced TJP1 expression, confirming gut barrier disruption and systemic inflammation. Omega-3 fatty acids supplementation selectively reduced IL-6 but did not reverse PPA-induced TNF-\u03b1 elevation or oxidative stress. CLDN2 expression increased in PPA + omega-3 rats, suggesting a compensatory but incomplete barrier response. Dopamine, serotonin, and SCFA levels showed upward trends with supplementation but were not statistically significant. Histological analysis demonstrated partial preservation of neuronal and intestinal structure in the PPA + omega-3 group. Overall, omega-3 fatty acids exerted modest anti-inflammatory effects but failed to fully restore oxidative balance or barrier integrity in aged rats, suggesting that omega-3 fatty acids may be more effective as a preventive rather than restorative intervention in ageing-related gut-brain axis disruption.",

Methods: Rats were randomly divided into normal, model, diazepam, THB monotherapy, PPD monotherapy, and THB + PPD combination groups. Evaluations included the pentobarbital sleep test, HE staining, ELISA, 16S rRNA sequencing, metabolomics, and Western blot. Results: Results demonstrated that the THB + PPD combination exhibited significant synergistic effects compared with monotherapies: the combination shortened sleep latency by 56.2% (vs. 44.2% for THB alone and 20.7% for PPD alone) and prolonged sleep duration by 112.8% (vs. 70.2% for THB and 59.6% for PPD) relative to the model group, while effectively restoring body weight gain. Histologically, combined treatment significantly alleviated hippocampal neuronal damage and increased the number of intact neurons in the dentate gyrus. Molecularly, it upregulated brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) levels, restored neurotransmitter balance (serotonin, dopamine, and glutamate), suppressed overactivation of the hypothalamic-pituitary-adrenal (HPA) axis (reducing corticotropin-releasing hormone and corticosterone), and decreased pro-inflammatory cytokine expression. Gut microbiota analysis revealed that the combination restored microbial homeostasis (increasing beneficial bacteria such as *Lactobacillus*) and modulated the glycine-serine-threonine metabolic pathway. Mechanistically, THB + PPD synergistically activated the PI3K/AKT neurotrophic pathway (p-PI3K and p-AKT expression increased by 1.9-fold and 2.5-fold, respectively, vs. model), inhibited the AGE/RAGE pro-inflammatory axis (RAGE expression decreased by 31.8%), and enhanced blood-brain barrier integrity by upregulating tight junction proteins (ZO-1, Occludin). Conclusions: THB combined with PPD exerts synergistic anti-insomnia effects through multi-level regulation of the microbiota-gut-brain axis, neurochemical balance, and key signaling pathways, providing a promising foundation for developing safe natural product-based combination therapies.",

The addition of Lactobacillus paracasei MBH3-2 shortened fermentation time, improved physicochemical properties, and promoted the accumulation of functional metabolites. Packaging OTR significantly influenced dissolved oxygen (DO) levels, which were negatively correlated with total viable counts, pH, water-holding capacity (WHC), sensory scores, and key metabolic indicators (P\u00a0<\u00a00.01). Maintaining low and stable DO helped preserve microbial viability and delay quality deterioration. In the PBM-packaged group, Lactobacillus paracasei MBH3-2 showed favorable metabolic adaptation, with early enrichment in Fatty acid and Purine metabolism, followed by activation of the TCA cycle, Glycolysis/Gluconeogenesis, and Biosynthesis of amino acids in later storage. These findings underscore the potential of PBM packaging to create a balanced storage microenvironment, providing a sustainable and functional strategy for probiotic dairy preservation.",

Rhubarb (RR) is widely applied to treat IS in the clinic. However, its underlying pharmacological mechanisms remain incompletely elucidated. To dissect the mechanism and pharmacological basis of RR's ability to ameliorate IS from the side of modulating tryptophan-kynurenine (TRP-KYN) metabolism and neuroinflammation. An embolic middle cerebral artery occlusion (MCAO) model was employed in rats to simulate human IS. Neurological deficit scores, hematoxylin-eosin, 2,3,5-triphenyltetrazolium chloride, alcian blue-periodic acid-Schiff staining, Western blotting, targeted metabolomics, immunofluorescence, and enzyme-linked immunosorbent assay were utilized to evaluate the efficacy of RR against cerebral ischemic injury, gut permeability, TRP-KYN metabolism levels, and neuroinflammation. Surface plasmon resonance and cell-based assays were further utilized to screen and validate potential bioactive ingredients of RR for the treatment of IS. In addition to mitigating cerebral ischemic damage, RR treatment substantially restored intestinal barrier function in IS rats by reducing leaky gut biomarkers, ameliorating histopathological alterations, and upregulating colonic tight junction proteins. Moreover, RR modulated TRP-KYN metabolism, concomitant with regulated expression and enzymatic activity of indoleamine 2,3-dioxygenase 1 (IDO-1) and the triggering receptor expressed on myeloid cells-1 (TREM-1) levels in both colon tissue and serum. Within the central nervous system, RR attenuated neuroinflammation triggered by MCAO through orchestrating microglial polarization and cytokine levels, accompanied by suppression of the TREM-1-mediated inflammatory signaling cascade. Chrysophanol 8-O-\u03b2-d-glucoside, rutinum, lindleyin, and (-)-catechin gallate from RR were identified as potential IDO-1 inhibitors, while rhein, lindleyin, methyl gallate, and chrysophanol 8-O-\u03b2-d-glucoside were identified as potential TREM-1 inhibitors, capable of attenuating the overexpression of IDO-1 and TREM-1 or TREM-1 and NOD-like receptor protein 3 (NLRP3). This study demonstrates that RR exerts therapeutic effects in IS by improving the intestinal barrier function, reprogramming the IDO-1-dependent TRP-KYN pathway, and attenuating neuroinflammation. These effects are attributed to its bioactive components, including rutinum, chrysophanol 8-O-\u03b2-d-glucoside, lindleyin, (-)-catechin gallate, rhein, and methyl gallate.",

Although peripheral determinants of barrier dysfunction have been studied, the contribution of central regulatory mechanisms remains unclear. \u03b2-Hydroxybutyrate (BHB), a major ketone body elevated during fasting, exhibits anti-inflammatory and barrier-protective effects peripherally, but its central actions are unknown. Here, we investigated whether BHB acts within the brain to regulate intestinal barrier function and visceral sensitivity using an LPS-induced rat model. Intracisternal BHB dose-dependently attenuated LPS-induced colonic hyperpermeability and visceral hypersensitivity, whereas an equivalent subcutaneous dose was ineffective, indicating a centrally mediated effect. The protection conferred by intracisternal BHB was abolished by vagotomy and by pharmacological inhibition of brain AMPK, orexin 1 receptors, histamine H1 receptors, basal forebrain cholinergic neurons (BFCNs), or adenosine A2B receptors. Peripheral BHB also ameliorated barrier dysfunction and visceral hypersensitivity; however, these effects persisted after vagotomy while remaining sensitive to central pharmacological blockade, suggesting engagement of shared brain signaling modules together with vagus-nonobligatory components. Collectively, these findings demonstrate that BHB regulates intestinal barrier function and visceral sensitivity through both central and peripheral mechanisms. Central BHB signaling engages an AMPK-orexin pathway involving histamine H1 receptors, BFCNs, adenosine A2B receptor-related mechanisms, and vagal pathways. BHB thus emerges as a neuro-metabolic signal modulating core gut-brain interaction processes and represents a promising therapeutic target for leaky gut-associated disorders, particularly IBS.",

Osteocalcin and osteoprotegerin showed sex-specific between-group differences: osteocalcin declined throughout weeks 0\u201224 in GY males, whereas osteoprotegerin declined during weeks 0\u201216 in GY females and was elevated at the end of the control period in WP females. C-terminal telopeptide of type I collagen and sclerostin showed intervention group-dependent, but not sex-dependent, differences. C-terminal telopeptide of type I collagen increased transiently from week 8 to week 16 and returned to baseline by week 24 only in GY. Sclerostin concentrations fluctuated, and at 24 wk, were not different from baseline in GY but were higher than baseline in WP. At week 16, interleukin (IL)-1\u03b2 increased in WP, and IL-6 decreased in GY. IL-10 and tumor necrosis factor \u03b1 increased during the control period and decreased with WP only in females. Increased protein intake, independent of source, was associated with modest, often sex-specific fluctuations in bone and inflammatory markers in adolescent athletes, potentially influenced by growth and training-related factors across the competitive season. This trial was registered at clinicaltrials.gov as NCT05922462.",

Goat milk fat globule membrane (GMFGM) derived from goat milk, is a membrane primarily composed of proteins and polar lipids that regulates the gut microbiota. However, its role in AD remains unclear. Therefore, we examined the neuroprotective effects of GMFGM in 5xFAD mice. Supplementation with GMFGM (400 mg/kg bw, 8 weeks) improved cognitive performance, reduced brain A\u03b2 deposition, alleviated neuroinflammation, and upregulated neurotrophic factors. Moreover, GMFGM preserved gut barrier integrity, lowered serum LPS levels, and reshaped gut microbiota composition, decreasing Alistipes, Dorea formicigenerans, and Duncaniella dubosii while increasing Stenotrophomonas. Further fecal microbiota transplantation validated the mechanism by which GMFGM ameliorates AD cognitive impairment by modulating the gut microbiota. These results indicate that GMFGM may rescue cognition by modulating the gut microbiota, alleviating gut damage, reducing LPS levels, and consequently inhibiting neuroinflammatory.",

Results from growth curves, acid production assays, and multiple microscopy techniques (laser scanning confocal microscopy, scanning electron microscopy, and transmission electron microscopy) collectively demonstrate that 256\u00a0AU/mL plantaricin BM-1 alters the morphology and cell membrane permeability of L. bulgaricus YR, reducing its acid production capacity while preserving its viability. Transcriptomic analysis revealed that this treatment significantly upregulated fatty acid metabolism and the gene LDB_RS05285, and downregulated atpE in L. bulgaricus YR. Metabolomics further revealed significant alterations in membrane-associated fatty acids and sterol lipids, corroborating BM-1's influence on cell membrane structure. Integrating observational, transcriptomic, and metabolomic data, it is concluded that 256\u00a0AU/mL plantaricin regulates post-fermentation acidification by modulating membrane permeability and structure, thereby controlling the expression of marker genes LDB_RS05285 and atpE. Storage experiments demonstrate that BM-1 addition maintains yoghurt pH\u00a0\u2265\u00a03.9 for 21\u00a0days at ambient temperature, effectively retarding post-acidification.",
"41962904": "ID: 41962904\nTitle: Clover Honey Limits Survival of Enterotoxigenic Escherichia coli in an In Vitro Gastric Model and Reduces In Vitro Fermentation pH of Small Intestine Microbes.\nAbstract: Honey has well-described antimicrobial properties in wound healing, but little is known about its effects within the gastrointestinal tract. We used in vitro gastric digestion and fermentation of clover honey to investigate its potential interactions with small intestine bacteria (SIB), the foodborne pathogen enterotoxigenic Escherichia coli (ETEC), and small intestine epithelial cells. In vitro gastric digestions of sterile-filtered honey, and a simple sugar control were performed with 1 \u00d7 108 colony-forming units (CFU)/mL ETEC H10407. ETEC CFU and pH were measured, and the resulting digesta were added to batch fermentations with SIB, in the form of a mock community or ileal aspirate from 6 healthy donors. SIB fermentations were characterized by 16S rRNA amplicon sequencing and application of fermentation supernatants to mature Caco-2 cell monolayers for analysis of changes in transepithelial electrical resistance (TEER) and interleukin (IL)-8 production. Differential abundance of bacterial taxa detected by 16S rRNA sequencing between the honey and sugar conditions was tested using an Analysis of Compositions of Microbiomes with Bias Correction 2. Differences in ETEC CFU, media pH, and changes in TEER and IL-8 production between the honey and sugar conditions were tested by linear mixed effects modeling with post hoc least-squares means analysis. Under pH 2.5 in vitro gastric digestion conditions, ETEC CFU decreased significantly (P < 0.0001) more in the presence of clover honey (0.0035% input) than in a sugar control (0.036% input). The pH of SIB fermentation media was significantly reduced (P < 0.0001) with digested honey relative to sugar. Honey fermentation supernatant from human ileal communities challenged with ETEC elicited a greater improvement in TEER (3.68 compared with -0.80, P = 0.0479) relative to the same fermentations performed with control. Honey limits the survival of ETEC H10407 within an in vitro gastric environment at low pH. Clover honey may also impart decreased pH and potential improvement in in vitro epithelial cell barrier integrity in the presence of a pathogen.",
"41966379": "ID: 41966379\nTitle: Yeast \u03b2-glucan alleviates alcohol-related brain injury by restoring gut-brain axis homeostasis.\nAbstract: This study investigated the protective effects of yeast \u03b2-glucan (YBG) against alcohol-related brain injury (ARBI), with a focus on potential mechanisms mediated by the gut-brain axis. Our findings revealed that YBG supplementation significantly alleviated alcohol-induced anxiety-like behaviors and cognitive deficits in mice. In the brain, YBG mitigated oxidative stress, reduced neuroinflammation, and ameliorated neurotransmitter dysregulation. In the gut, YBG protected the alcohol-damaged intestinal barrier, upregulating the expression of tight junction proteins (Claudin-1, Occludin, and ZO-1) by 1.5- to 4.5-fold. Furthermore, YBG modulated the gut microbial community, markedly increasing the relative abundance of genera such as Akkermansia (from 0.13% to 4.3%) and Lactobacillus (from 0% to 0.89%), while suppressing alcohol-associated taxa including Alistipes (from 0.20% to 0.05%) and Colidextribacter (from 0.61% to 0.01%). These gut-level ecological changes were accompanied by significant shifts in the microbial metabolome, including elevated short-chain fatty acid levels and altered profiles of neuroactive amino acids, particularly L-tryptophan and L-tyrosine (which exhibited 2.9- and 2.7-fold increases, respectively). KEGG pathway analysis revealed that differential metabolites were primarily enriched in amino acid biosynthesis pathways. Correlation analysis showed strong positive associations among YBG-enriched bacteria, favorable metabolites, and markers of brain health. Together, these findings suggest that YBG's protective effects against ARBI are closely associated with the restoration of gut barrier integrity, restructuring the gut microbiota, and modulating microbial metabolism, which collectively correlate with the attenuation of neuroinflammation and oxidative stress.",
"41968102": "ID: 41968102\nTitle: Effects of gut barrier dysfunction during a viral respiratory disease challenge on immune function of feedlot beef calves.\nAbstract: Feedlot morbidity and mortality have increased in recent decades, driven in part by the prevalence of bovine respiratory disease (BRD). Research on gut barrier dysfunction (GBD) reveals similarities in predisposing factors and etiopathogenic mechanisms to BRD. This overlap suggests that GBD may serve as a predisposing factor, increasing susceptibility to BRD. To explore this connection, 15 Angus \u00d7 Holstein heifers (initial body weight\u2009=\u2009475\u2009\u00b1\u200912\u2009kg) were used in a randomized complete block design experiment to evaluate the effects of induced changes in intestinal permeability on immune responsiveness during a viral respiratory disease challenge. Treatments were control (CT; n\u2009=\u20097) or GBD (n\u2009=\u20098), where GBD heifers underwent a protocol to increase gut permeability using aspirin (100\u2009mg/kg of body weight every 12\u2009h for 4 consecutive days). Daily dry matter intake and average daily vaginal temperature (DVT) were continuously recorded. After aspirin withdrawal, all heifers were inoculated with bovine herpesvirus-1. Complete blood count, cytokines, acute-phase proteins (APP), cortisol, and intestinal morphology were evaluated. Heifer was considered the experimental unit for all analyses. The statistical model included the fixed effect of treatment and hour/day and the resultant interactions, run and heifer (treatment) were used as random effects, and hour or day was the term for all repeated statements, and heifer (treatment) was the subject. Aspirin administration increased gut permeability in GBD heifers, as evidenced by greater plasma Chromium-EDTA recovery (P\u2009=\u20090.02) and increased lipopolysaccharide-binding protein concentration (treatment \u00d7 hour; P\u2009<\u20090.01) early in the disease challenge. Compared to CT, GBD heifers tended to exhibit decreased DVT (P\u2009=\u20090.10) and haptoglobin concentration (treatment \u00d7 hour; P\u2009=\u20090.06) by the end of the disease challenge. No significant differences were observed in serum amyloid A, interleukin-6, tumor necrosis factor-\u03b1, interleukin-10, or cortisol concentration (P\u2009\u2265\u20090.20). A tendency for decreased white blood cell (P\u2009=\u20090.08) and lymphocyte counts (treatment \u00d7 hour; P\u2009=\u20090.08) in GBD heifers was observed. There were no effects of treatments on intestinal morphology (P\u2009\u2265\u20090.16). These findings suggest that increased gut permeability influences immune responses by reducing the febrile response and decreasing the production of some APP. Greater emphasis on gut health could improve disease outcomes in BRD management. Death loss associated with bovine respiratory disease (BRD) has continued to rise in recent decades, and as such, new approaches should be sought to mitigate BRD. Research suggests that the predisposing factors of gut barrier dysfunction (GBD) are like BRD in that they can both be triggered and aggravated by stress events, thus, they may occur simultaneously. GBD describes a disease state in the gastrointestinal tract that increases the exposure of blood circulation to microorganisms that naturally reside in the small intestine, resulting in inflammation. Gut health may affect disease outcomes because the gastrointestinal barrier is the body\u2019s largest immune organ, and supporting the immune response imposes a significant energetic cost. This energetic burden that GBD imposes on the body should be considered in terms of its ability to affect overall health outcomes. In this experiment, heifers were (GBD group) or were not (control group) subjected to a protocol that induced GBD. All heifers were then subjected to a respiratory disease challenge, and important indicators of the immune response were measured. Heifers with increased gut permeability exhibited a decreased febrile response, which may suggest a less robust early immune activation, as fever is an important part of the normal response to infection. These heifers also displayed altered acute\u2011phase protein production, which may influence how efficiently cattle can control and recover from infection. These results suggest that gut health may play a significant role in overall cattle immunity and should be given greater consideration in the effort to improve disease outcomes.",
"41968935": "ID: 41968935\nTitle: The end of 'leaky gut': pathway-specific mechanistic approaches to barrier restoration.\nAbstract: For over 50\u200ayears, increased intestinal permeability has been associated with diverse inflammatory and systemic diseases. Yet the oversimplified concept of 'leaky gut' as a singular phenomenon has limited both mechanistic understanding and therapeutic development. It is now recognized that intestinal permeability occurs via two molecularly distinct, differentially regulated trans-tight junction pathways, while a tight junction-independent unrestricted pathway allows flux at sites of epithelial damage. The pore pathway is a high-conductance, size-selective and charge-selective flux route that mediates ion and water flux. Its upregulation can be either protective, as in infectious enterocolitis, or pathogenic, as in immune-mediated disease or, as shown recently, in sepsis. Myosin light chain kinase activation enhances flux across the leak pathway, a low-conductance macromolecular flux route, that promotes progression of immune-mediated diseases. Recently developed molecularly targeted, pathway-specific approaches to barrier restoration are effective and can outperform current therapies without the complications of broad immunosuppression. The evolving pathway-resolved framework transforms intestinal barrier biology from a descriptive science into mechanism-specific therapeutic approaches that have promise as independent agents and as complements to available immune-targeted therapies.",

We asked whether probiotic fermentation enriching PPD-type ginsenosides converts ginseng into a potent, low-dose antiaging agent. In D-galactose-aged mice, 20 mg/kg of probiotic-fermented ginseng (GFB) outperformed 600 mg/kg native ginseng: Rg3/Rg5/Rd and antioxidant capacity surged, cytokines fell, redox balance, barrier integrity, and youthful microbiota were restored. Plasma 20(S)-protopanaxadiol (PPD) increased 4-6-fold only in fermented-ginseng mice; PPD down-regulated barrier-destabilizing genes and docked stably into CC-chemokine receptor 6 (CCR6), suggesting a potential mechanism for blocking CCL20-driven chemotaxis. Thus, fermentation transforms ginseng into a food-grade, microbe-activated pro-drug that delivers systemic PPD, antagonizes CCR6, and simultaneously quells inflammation, seals the gut, and resets redox homeostasis for precision geroprotection.",
"41995207": "ID: 41995207\nTitle: Effect of Capsicum annuum leaf extract addition timing on yogurt bioactivity, digestibility, and cellular antioxidant defence.\nAbstract: Capsicum leaves contain notable levels of bioactive compounds, making them a potential functional ingredient for fermented dairy systems. During fermentation, microbial activity can modify these compounds, suggesting that the timing of extract incorporation may influence product quality. In this study, yogurt was supplemented with capsicum leaf extract (CLE) either before fermentation (Pre-L) or after fermentation (Post-L) to compare the effects of microbial exposure on physicochemical properties, bioactive activities, digestibility, and cellular antioxidant responses. CLE moderated acidification, with Pre-L maintaining a higher pH during fermentation. LAB viability was above 8 log CFU g-1 throughout storage in all samples. CLE supplementation increased phenolic content and antioxidant activity, with Pre-L showing superior retention during storage. In contrast, Post-L preserved enzyme-inhibitory activity more effectively, with smaller losses in \u03b1-amylase and \u03b1-glucosidase inhibition compared to Pre-L. During in vitro digestion, CLE enhanced phenolic bioaccessibility and proteolysis. Peptidomic analysis revealed approximately two-fold higher soluble peptide abundance in Pre-L, while Post-L showed the greatest hydrolysis during intestinal digestion, confirming timing-dependent modulation of proteolysis. In RAW 264.7 macrophages, CLE-supplemented yogurts reduced H2O2-induced oxidative stress and preserved antioxidant defence, with Pre-L showing the strongest cytoprotection. Overall, the timing of incorporation offers distinct benefits. Pre-L enhances antioxidant retention and cellular protection, whereas Post-L improves protein digestibility.",
"42003478": "ID: 42003478\nTitle: JNK2 Is a Stress Integrator Driving Atrial Fibrillation Pathogenesis in Aging via Gut-Heart Crosstalk.\nAbstract: Atrial fibrillation (AF) is the most common arrhythmia and is associated with high morbidity and mortality, particularly in the aging population. Current treatment and prevention strategies remain suboptimal, highlighting the urgent need to better understand the mechanisms underlying aging-associated AF. We recently reported a causal role of the stress-activated kinase JNK2 (c-Jun N-terminal kinase 2) in aging-associated AF pathogenesis, mediated by JNK2-driven sarcoplasmic reticulum Ca2+ dysfunction. However, the mechanisms by which cardiac JNK2 is activated during aging to promote AF remain unclear. Emerging evidence suggests that interorgan crosstalk contributes critically to the development of cardiovascular diseases. A hyperpermeable gastrointestinal epithelial barrier (\"leaky gut\"), commonly observed in aged individuals, is associated with elevated levels of proinflammatory cytokines and an increased risk of AF. Although proinflammatory cytokines have been proposed as predisposing factors for AF, clinical and experimental studies have yielded inconsistent results, underscoring the complexity of inflammation-associated AF pathogenesis. Here, we investigated whether cardiac JNK2 integrates diverse stress stimuli, including proinflammatory cytokines and lipopolysaccharide, to drive AF pathogenesis. We used aged mice, intestinal epithelium-specific tight junction OD (occludin) knockdown (OD+/-) mice, and a well-established dextran sulfate sodium-induced leaky gut mouse model characterized by reduced gastrointestinal epithelial occludin expression. A series of physiological and molecular approaches was applied to assess cardiac and gastrointestinal responses. We found that leaky gut significantly activates atrial JNK2, which, in turn, drives Ca2+-triggered arrhythmic activity and increases AF inducibility in aged, dextran sulfate sodium-treated, and OD+/- mouse models. Restoration of gut barrier function in dextran sulfate sodium mice, a clinically relevant model, reduced AF susceptibility. Similarly, either JNK2 inhibition or TNF-\u03b1 (tumor necrosis factor \u03b1) blockade abolished the increased AF risk associated with leaky gut. Furthermore, we demonstrate, for the first time, that leaky gut-associated proinflammatory cytokines, including TNF-\u03b1 and IL-17A (interleukin-17A), together with lipopolysaccharide, activate cardiac JNK2. This activation promotes AF pathogenesis through JNK2-mediated arrhythmogenic mechanisms, including diastolic sarcoplasmic reticulum Ca2+ leak, Ca2+ waves, and delayed afterdepolarizations. Activated JNK2 functions as a pathological nodal integrator of leaky gut-associated stress signals, mediating gut-to-heart crosstalk and driving inflammation-induced AF pathogenesis. Targeting JNK2 may represent a novel therapeutic strategy for AF.",

From a pharmaceutics standpoint, their therapeutic performance is often cargo-governed (e.g., microRNAs and proteins) and is ultimately constrained by delivery determinants such as stability, biodistribution, cellular uptake, and intracellular trafficking. In this review, we compare animal-derived exosomes (ADEs) and PELNs through a formulation-centric lens, emphasizing how source-dependent molecular composition shapes critical delivery behaviors and translational feasibility. We reorganize representative preclinical evidence into pharmaceutics-relevant delivery scenarios-including systemic/vascular targeting, blood-brain barrier transport, oral gastrointestinal delivery, and tumor microenvironment modulation-to connect cargo identity with exposure-site interactions and pharmacodynamic outcomes. We further discuss engineering strategies for improving payload control, targeting precision, and dosing accuracy, including endogenous enrichment, exogenous loading, and surface functionalization, while highlighting scale-up and safety considerations introduced by modification. Finally, we delineate translational priorities required to advance exosome-based products toward clinical development: standardized dose metrics (particle- and cargo-normalized), quantitative PK/biodistribution-PD relationships, potency assays and critical quality attributes (CQAs), manufacturing consistency under GMP, and regulatory-compliant characterization. Collectively, this review reframes ADEs and PELNs as cargo-driven pharmaceutical delivery systems and provides a practical roadmap for translation, with particular attention to the oral and scalable potential of PELNs.",
"42009106": "ID: 42009106\nTitle: Chronic inflammation in virus-suppressed people living with human immunodeficiency virus infection: A microbiology-oriented perspective on gut barrier failure, microbial translocation, and immune activation.\nAbstract: Potent antiretroviral therapy (ART) has transformed human immunodeficiency virus (HIV) infection into a chronic manageable condition; however, many people living with HIV (PLWH) exhibit persistent immune activation and inflammation despite long-term virological suppression. Residual inflammation is strongly associated with an increased risk of cardiovascular disease, chronic kidney disease, metabolic dysfunction-associated steatotic liver disease, cancer, and neurocognitive impairment. This review summarizes the current evidence on the microbiology-oriented mechanisms that sustain this state. We first outline a multifactorial network in which incomplete repair of intestinal mucosal damage, dysbiosis, reduced short-chain fatty acid production, and disturbed bile acid metabolism generate a patchy \"leaky gut.\" Continuous translocation of bacterial lipopolysaccharide, fungal \u03b2-D-glucan, and other microbial products activates monocyte-macrophage and portal-liver inflammatory circuits. These inputs interact with intermittent HIV antigen expression from latent reservoirs, inflammatory cell death, chronic coinfections, lymphoid tissue fibrosis, mitochondrial dysfunction, and traditional lifestyle-related risk factors. Together, they establish a self-reinforcing gut-liver-immune axis that maintains low-grade inflammation and a procoagulant milieu under viral suppression. We then link these mechanisms to organ-specific complications and review the intervention data, focusing on early ART initiation, statin therapy, and cotrimoxazole prophylaxis as a proof-of-concept that modifying inflammatory and mucosal pressures can improve outcomes. Finally, we highlight research priorities and argue that the effective prevention of long-term complications in virally suppressed PLWH requires combination strategies targeting multiple nodes of this network, with particular attention to gut barrier repair and microbiome modulation.",
"42033495": "ID: 42033495\nTitle: Inhibition of SARS-CoV-2 spike S1-ACE2 binding interaction and downregulation of ACE2 gene expression by Malaysian stingless bee honey and its bioactive compound, stilbamidine (SDC).\nAbstract: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus infects host cells by binding to angiotensin-converting enzyme 2 (ACE2). Stilbamidine (SDC), a compound identified in Malaysian Kelulut honey (KH), has been reported to exhibit favourable binding affinity towards ACE2. This study aims to determine the effects of KH and SDC on the binding of spike protein to the ACE2 receptor, as well as to assess their modulatory potential on ACE2 gene and protein expression in lung and kidney cells. KH, SDC, and MLN 4760 (ACE2 inhibitor) were tested using an in vitro spike S1:ACE2 inhibition assay. Their modulatory effects on the ACE2 gene and protein expression were further examined through real-time PCR and western blot analysis. KH inhibited the binding of Spike S1 to ACE2, surpassing MLN4760, with maximum effects (Emax) of 82.66\u2009\u00b1\u20090.24% and 59.81\u2009\u00b1\u20098.00%, respectively, while the Emax for SDC was 19.93\u2009\u00b1\u20090.4%. KH caused a significant, dose-dependent downregulation of ACE2 gene expression in kidney-derived Vero E6 cells after 24\u00a0h of treatment, whereas SDC reduced ACE2 gene expression in lung-derived A549-ACE2-TMPRSS2 cells after 72\u00a0h. Nevertheless, ACE2 protein expression remained unchanged following both treatments. KH and SDC inhibit the binding of the SARS-CoV-2 spike S1 protein to the ACE2 receptor and reduce ACE2 gene expression. The efficacy of ACE2-targeted interventions may be limited by ACE2 polymorphisms and inter-individual expression differences. Further in vivo studies are needed to confirm their prophylactic and therapeutic potential against SARS-CoV-2 infection.",
"42111070": "ID: 42111070\nTitle: Microbiota and Guillain-Barr\u00e9 syndrome: role of microbial metabolites, biomarkers, and emerging therapeutic strategies.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is an acute autoimmune polyradiculoneuropathy that follows infection and is characterized by immune-mediated demyelination or axonal injury of the peripheral nervous system. While established triggers such as Campylobacter jejuni are well recognized, increasing evidence implicates the gut microbiota as a key modulator of immune responses relevant to GBS pathogenesis. The intestinal microbiota produces a diverse array of bioactive metabolites, including short-chain fatty acids (SCFAs), tryptophan-derived indoles, and neurotransmitter-like molecules, which influence immune tolerance, gut barrier integrity, and neuroinflammatory signaling. SCFAs, particularly butyrate, exert anti-inflammatory effects and support epithelial and blood-nerve barrier function. Microbial tryptophan metabolites regulate astrocyte and microglial activity via aryl hydrocarbon receptor (AHR) signaling, thereby restraining central and peripheral neuroinflammation. In contrast, dysbiosis-associated metabolites such as lipopolysaccharide (LPS) may enhance systemic inflammation, disrupt immune tolerance, and promote autoantibody production through mechanisms including molecular mimicry. Studies suggest that specific microbial taxa and metabolite signatures may serve as diagnostic or prognostic biomarkers in GBS, offering insights into disease susceptibility and progression. Microbiota-targeted therapeutic strategies are emerging as promising adjuncts to immunotherapy. Probiotics and prebiotics may restore beneficial microbial communities and rebalance immunoregulatory metabolite production, while host-directed metabolic interventions such as creatine supplementation may further support mitochondrial function, immunometabolic homeostasis, and neuroprotection. Fecal microbiota transplantation (FMT), though still experimental in GBS, has shown benefit in related neuroinflammatory disorders by reestablishing eubiosis and dampening immune activation. Future studies integrating metagenomic, metabolomic, and immunologic profiling in well-characterized GBS cohorts are essential to validate these findings and advance personalized microbiota-based interventions.",

Our previous study showed enhanced shelf-life with stable functional metabolites of soy yoghurt fermented with Leuconostoc mesenteroides strain SB1075. Building on these findings, we prepared a new batch of SB1075-fermented soy yoghurt for animal experiments and evaluated its antidiabetic potential using transcriptomic and metabolomic approaches. GC-MS profiling confirmed reproducible metabolite patterns in fermented soy yoghurt, with the putative presence of bioactive compounds including D-pinitol and myo-inositol. Soy yoghurt was administered orally (as lyophilised powder) at the doses of 100, 200, and 400\u00a0mg/kg body weight to streptozotocin (STZ)-induced diabetic Swiss albino mice for 5\u00a0weeks, with unfermented soymilk as a control. The 100\u00a0mg/kg dose produced the most pronounced metabolic improvement, markedly reduced fasting blood glucose (90.75\u00a0\u00b1\u00a08.72 vs 421.5\u00a0\u00b1\u00a028.94\u00a0mg/dL in diabetic controls, p\u00a0\u2264\u00a00.001), improving glucose tolerance, and restoring lipid and liver biochemical parameters. Transcriptomic analysis of the intestinal tissue revealed upregulation of genes associated with insulin signalling and glucose metabolism genes (Insr, Irs1, Gck, & Pklr) alongside downregulation of inflammatory mediators (Il6 and Tnf). Metabolomic profiling further indicated differential abundance of several putatively annotated metabolites linked to metabolic regulation and oxidative stress responses. Collectively, these findings suggest that fermentation of SB1075-fermented soy yoghurt enhances the functional metabolite profile and may contribute to improved glycaemic regulation in diabetic mice. However, further studies involving targeted validation and clinical investigations will be required to confirm these mechanistic insights and evaluate the translational potential of SB1075-fermented soy yoghurt as a functional dietary intervention for metabolic health.",

Five honey samples from four municipalities in the Midwest of Brazil (Mato Grosso state) were evaluated in this study. Samples of fresh honey and its hexane, ethyl acetate, and n-butanol fractions were prepared by the fractional extraction method in a separating funnel using each fraction's solvent. Antibacterial activities were assessed using the broth microdilution method with serial dilution of the samples ranging from 1000 to 1.95\u03bcg/ml. Outer membrane permeability was determined by the broth microdilution method with a combination of honey or solvent extract fraction (80-0.15mg/ml) and clarithromycin and erythromycin (20-0.04\u03bcg/ml) prepared in a checkerboard. Time-kill assays were performed at 2, 4, 8 and 24h. At a concentration of 1000\u03bcg/ml, no antibacterial activity was observed, with inhibition below 24% for two bacteria. Honey 1 (80mg/ml) and its n-butanol fraction increased the outer membrane permeability of E. faecalis when combined with clarithromycin (20\u03bcg/ml), but no effect on membrane permeability of E. faecalis was observed for the remaining r four honey samples and their fractions. None of the samples affected the membrane permeability of S. epidermidis. We concluded that honey 1 increase the antibacterial activity of clarithromycin and erythromycin against E. faecalis, possibly due to the action of flavonoids.",

A hedonic test was used for sensory evaluation, along with texture analysis, water holding capacity, pH, acidity, viscosity, MTT assay, and INFOGEST digestion model (SDS-PAGE, degree of hydrolysis). Optimal concentration was 1.0% (w/v). Three fractions-high (H-\u03b2G), medium (M-\u03b2G), and low (L-\u03b2G) MW-were prepared by acid hydrolysis. M-\u03b2G gave the best sensory attributes, while H-\u03b2G showed highest firmness and viscosity. H-\u03b2G did not impede acidification, whereas M-\u03b2G and L-\u03b2G initially slowed acidification but increased early starter metabolic activity. M-\u03b2G and L-\u03b2G promoted gastric protein hydrolysis (higher degree of hydrolysis, faster SDS-PAGE band disappearance), while H-\u03b2G mildly delayed proteolysis due to high viscosity.

"42148126": "ID: 42148126\nTitle: All roads lead to NF-\u03baB: the NF-\u03baB pathway as a major target for intestinal inflammatory disorders.\nAbstract: This review aims to comprehensively examine the role of the NF-\u03baB signalling pathway as a central mediator of intestinal inflammation, integrating evidence from microbiota dysbiosis, immune activation, neutrophil extracellular trap (NET) formation, and the gut-brain axis, and to evaluate current and emerging NF-\u03baB-targeted therapeutic strategies for inflammatory intestinal disorders. The NF-\u03baB family comprises transcription factors that control key processes in immune responses and inflammation by regulating specific gene expression. NF-\u03baB signalling mediates intestinal inflammatory responses at different levels including cytokine secretion, inflammasome signalling, the recruiting of immune cells and antibody production. The NF-\u03baB pathway acts as sensor of microbiota changes and is strongly activated by bacterial toxins such as LPS, MDP or TMAO. Thus, microbial dysbiosis activates pro-inflammatory NF-\u03baB, producing epithelial barrier dysfunction that can lead to a \"leaky gut\" syndrome, allowing pro-inflammatory factors to leak into the systemic circulation. Consequently, the inflammation originating in the intestine spreads to other organs like the brain, where it might contribute to the development of neurodegenerative disorders, such as Parkinson's disease. In addition, NF-\u03baB also promotes intestinal inflammation in response to Neutrophil Extracellular Traps (NETs) formation, promoting tissue damage and lesions of the intestinal epithelial lining. Therefore, a dysregulated NF-\u03baB signalling appears often in multiple chronic intestinal inflammatory conditions, such as Crohn's Disease (CD) and Ulcerative Colitis (UC), Celiac Disease (CeD) or microscopic colitis. In addition, NF-\u03baB is strongly activated in Irritable Bowel Syndrome (IBS) and in acute intestinal inflammation such as Necrotizing Enterocolitis (NEC). Confirming this evidence, inhibition of the NF-\u03baB pathway by drugs, peptides or natural compounds has been demonstrated to ameliorate the symptoms in many of these inflammatory diseases. In this review, we explore the role of the NF-\u03baB pathway in intestinal inflammation, given its essential role in linking microbiota dysbiosis, infections and chronic inflammation. Finally, we propose the NF-\u03baB pathway as a main therapeutic target for inflammatory intestinal disorders and discuss current inhibitory therapies in use.",

Gut microbiota dysbiosis and elevated lipopolysaccharide levels are established features of Alzheimer's disease, and growing evidence indicates that this dysbiosis drives neuroinflammatory disease progression. Yet the upstream trigger initiating this dysbiosis remains unknown. We propose that age-related copper dyshomeostasis serves as this missing trigger. The redox-active copper content of ceruloplasmin increases across the adult lifespan, and copper is selectively toxic to anaerobic bacteria, preferentially affecting butyrate-producing genera including Faecalibacterium, Roseburia, and Coprococcus while sparing copper-resistant species. This selective toxicity is supported by animal studies demonstrating copper-induced elimination of butyrate producers with reversible gut barrier damage and by Wilson's disease cohorts showing consistent depletion of butyrate-producing genera due to elevated copper levels. The resulting dysbiosis creates a triple inflammatory pathway: butyrate loss compromises gut barrier integrity and removes histone deacetylase-mediated suppression of neuroinflammation; the increase of Gram-negative bacteria elevates lipopolysaccharide translocation through the compromised barrier; and impaired blood-brain barrier integrity reduces amyloid-\u03b2 clearance. These three insults trigger microglial activation through NF-\u03baB signaling, creating a 'triple hit' on a single transcription factor that may explain the magnitude of neuroinflammatory effects observed in Alzheimer's disease. This mechanism explains the increased acetate/butyrate ratio recently identified as a biomarker distinguishing Alzheimer's-related from non-Alzheimer's cognitive impairment (AUC 0.951), since copper disrupts microbial metabolic cross-feeding networks that convert acetate to butyrate. We present specific, falsifiable predictions that can be tested in human cohorts and propose copper as a novel upstream therapeutic target for Alzheimer's disease prevention.",

Strength training (ST) combined with adequate protein intake is a key element in reversing and improving functional capacity. Protein, especially Whey Protein isolates (WPI), is widely used to improve muscle mass. In contrast, high-protein products, such as protein yogurt (PY), may offer similar benefits for muscle health and drive additional effects on gut health, which is altered in older adults. For this, we aim to compare WP and PY supplementation during ST on body composition, strength, and gut microbiome in untrained older adults.\u00a0Seventeen untrained adults (60-70 years) were randomized to either consume WP (25 g) or PY (24.5 g) along with an 8-week supervised ST program (3 sessions/week). Initial and final assessments included body composition (BIA), strength (10RM, isokinetic torque, handgrip), gait speed, resting metabolic rate, and gut microbiome (16 S rRNA sequencing). Data were analyzed using repeated-measures ANOVA and diversity metrics. Both groups increased skeletal muscle mass (WP: +0.47 kg; PY: +0.50 kg) and improved strength and gait speed (p\u2009<\u20090.01), with no between-group differences. Fat mass decreased only in WP (p\u2009=\u20090.02), while resting metabolic rate increased in PY (p\u2009=\u20090.03). Microbiome analysis revealed distinct shifts: WP increased the Firmicutes/Bacteroidota ratio and enriched Subdoligranulum, whereas PY enhanced alpha diversity and increased the abundance of Coprococcus. Functional pathway predictions indicated differential enrichment in metabolic and signaling processes. High-protein yogurt and whey protein similarly improve muscle mass, strength, and functional capacity during ST, while exerting distinct effects on gut microbiome composition. Yogurt represents a cost-effective alternative to whey protein and may confer additional gut health benefits.Trial registration: Clinicaltrials.gov identifier NCT06412302.

Here, we demonstrate that the probiotic Limosilactobacillus reuteri (L. reuteri) ameliorates behavioral deficits and cortical dysfunction in offspring from a maternal immune activation (MIA) mouse model of ASD through two synergistic gut-brain pathways. Mechanistically, L. reuteri restores gut barrier integrity and attenuates inflammation by reprogramming colonic lipid metabolism toward cholesterol biosynthesis. Critically, cholesterol synthesis is indispensable for L. reuteri's therapeutic effects, as demonstrated by the fact that statin-mediated inhibition of cholesterol synthesis abolishes the benefits on gut barrier function and neurobehavior. Moreover, L. reuteri elevates serum levels of N-oleoyldopamine (OLDA), an endogenous lipid amide that crosses the blood-brain barrier and attenuates neuroinflammation. Exogenous OLDA administration alone is sufficient to attenuate neuroinflammation and ameliorate neurobehavioral and cortical dysfunction in MIA offspring. Together, these findings delineate a gut-brain axis mechanism by which L. reuteri counteracts MIA-induced autism-like behaviors, highlighting the therapeutic potential of targeting microbial-lipid crosstalk in ASD.",

Bovine organ extracts, and glandular therapy in general, became popular in the 1900s, but their effect on healthy aging is unexplored, and their mechanisms of action are unclear. Here, we evaluated three bovine thymus materials with regards to their effect on healthy aging in C. elegans: two thymus extracts, a nuclear fraction (TNF) and a cytosolic fraction, and desiccated bovine thymus. All three materials extended C. elegans mid-life survival and improved mid-life motility. RNA sequencing revealed that TNF treatment elicited noticeable changes in the expression of genes related to the extracellular matrix and those necessary for defense responses. This was accompanied by protection from oxidative stress (paraquat) and pathogen (Pseudomonas aeruginosa)-induced early death and leaky gut. This study validates the hypothesis that dietary supplementation with bovine thymus extract can support healthy aging and protect C. elegans from environmental stressors.",

Intestinal health: Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium lactis BB-12 reinforce epithelial integrity via upregulation of tight-junction proteins (occludin, claudin-1), attenuate inflammation through cytokine modulation (\u2191IL-10, \u2193TNF-\u03b1, IL-6), and restore eubiosis in conditions including IBS, constipation, and antibiotic-associated diarrhea. Neurologic health: \"Psychobiotic\" strains (e.g., L. rhamnosus JB-1, B. longum 1714, L. helveticus R0052 + B. longum R0175) modulate neurotransmitter synthesis (GABA, serotonin), dampen HPA-axis hyperactivity, and reduce neuroinflammation, yielding improvements in anxiety, stress resilience, cognitive function, and slowing brain-atrophy progression in MCI and Alzheimer's disease. Cardiovascular health: Meta-analyses of 30+ RCTs demonstrate that probiotic supplementation (notably L. acidophilus, L. plantarum, B. longum) lowers total and LDL cholesterol (-7 to -10 mg/dL) via bile-salt hydrolase activity, SCFA-mediated GPR signaling, direct cholesterol assimilation, and modestly reduces systolic (-2 to -4 mmHg) and diastolic blood pressure through anti-inflammatory pathways and improved endothelial function. Safety: While generally safe in healthy populations, rare adverse events (bacteremia, D-lactic acidosis, horizontal gene transfer) have been reported in immunocompromised or critically ill individuals, underscoring the need for individualized risk-benefit assessments and rigorous adverse-event surveillance. Probiotics exert strain-specific, multimechanistic benefits on gut barrier integrity, neuroendocrine signaling, and cardiometabolic regulation. To fully realize their therapeutic promise, future research must pursue large-scale, head-to-head clinical trials, integrate multiomics and precision-design approaches, and establish standardized frameworks for safety monitoring and personalized formulation.",
"42183902": "ID: 42183902\nTitle: PRDX2 Mediates the Neuroprotective Role of Umbilical Cord Blood Exosomes via the CYP2J2/8,9-EET Pathway in Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a severe neurodegenerative disorder marked by progressive dopaminergic loss, oxidative stress, metabolic dysregulation, and neuroinflammation. Umbilical cord blood-derived exosomes (UCB-Exos) have emerged as a promising cell-free therapeutic strategy, yet the precise molecular mechanisms underlying their neuroprotective properties remain largely unknown. This study highlights Peroxiredoxin-2 (PRDX2) as an important antioxidant protein within UCB-Exos that mediates their neuroprotective effects in PD models. Using advanced multi-omics approaches, including proteomics, metabolomics, and transcriptomics, we demonstrate that PRDX2 is selectively enriched in UCB-Exos compared to peripheral blood-derived exosomes. UCB-Exos, through the delivery of PRDX2, partially restore antioxidant defenses in neurons, attenuate neuroinflammation, and promote cellular survival. Moreover, UCB-Exos were found to modulate arachidonic acid metabolism by upregulating the levels of 8,9-epoxyeicosatrienoic acid (8,9-EET), a key metabolite with anti-inflammatory properties. Mechanistically, PRDX2 appears to protect the enzyme CYP2J2 from oxidative degradation, facilitating the production of 8,9-EET and reducing the NF-\u03baB/COX-2-driven inflammatory response, thus potentially mitigating neurodegeneration. This study provides evidence for a potential pathway, the PRDX2-mediated metabolic regulatory pathway, and highlights the therapeutic potential of UCB-Exos, offering a novel strategy in the development of exosome-based treatments targeting oxidative stress and neuroinflammation in neurodegenerative diseases.",
"42184521": "ID: 42184521\nTitle: Balancing the modulation of soy protein structure to achieve improved texture and reduced antigenicity in soy yogurt: A practical approach of proteolytic pretreatment and lactic acid bacteria fermentation.\nAbstract: Achieving multiple goals in complex food systems requires precise protein modification. Soy yogurt, a promising plant-based alternative, suffers from poor texture and allergenicity. Few studies have investigated strategies for this dual goal or the mechanisms involved. A two-step strategy combining proteolytic pretreatment with lactic acid bacteria fermentation was developed to address both issues. Soymilk was pretreated with papain, alkaline protease or Flavourzyme (100-1300\u00a0U/g) before fermentation. Flavourzyme pretreatment maximized hydrolysis efficiency and significantly softened soy yogurt texture. A critical hydrolysis threshold (\u223c17%) is identified for optimal texture, yielding reduced psizes (\u223c15\u00a0\u03bcm) and minimized syneresis (26.8%-29.7%). Antigenicity reduction depends on epitope specificity rather than hydrolysis degree. Flavourzyme pretreatment reduced antigenicity to 1.28% at 700\u00a0U/g (77%-96% degradation of major epitopes) and ultimately to 0.77% at 1300\u00a0U/g. Coordinating psize with targeted degradation of allergenic epitopes therefore offers a practical strategy for plant-based yogurt systems.",
"42184753": "ID: 42184753\nTitle: Physical activity and the brain barriers: Mechanisms of neuroprotection and disease resilience.\nAbstract: The central nervous system (CNS) is protected by specialized barriers, including the blood-brain barrier (BBB), the blood-cerebrospinal fluid barrier, and the meningeal barriers, which collectively regulate molecular exchange and maintain neural homeostasis. Increasing evidence demonstrates that these barriers are not static structures but dynamically respond to systemic physiological stimuli like physical activity (PA), a voluntary behavior that elicits systemic physiological adaptations. This review summarizes current knowledge on the structural and functional organization of the CNS barriers, key biomarkers of their integrity, and the mechanisms through which PA modulates barrier function and properties. Available data consistently indicate that regular PA enhances BBB stability by upregulating tight junction proteins, reducing oxidative stress, suppressing pro-inflammatory signaling, improving endothelial function, and modulating the kynurenine pathway. PA-induced adaptations also appear to strengthen barrier resilience under both physiological conditions and in pathological states, such as ischemic stroke, traumatic brain injury, neurodegenerative diseases, and stress-related psychiatric disorders. Collectively, the evidence supports the concept that PA can act as a non-pharmacological strategy promoting CNS barrier integrity and neurovascular health. However, further mechanistic and longitudinal studies are required to clarify dose-response relationships, PA modality-specific effects, and translational implications for clinical populations, while also integrating the coordinated roles of multiple CNS barriers and addressing potential sex-specific differences in these responses.",

Recent research underscores the Forkhead box O (FOXO) family of transcription factors (FOXO1, FOXO3, FOXO4, FOXO6) as crucial regulators of these pathogenic processes. FOXOs regulate antioxidant defenses, autophagy, mitochondrial quality control, and apoptosis by functioning downstream of insulin/PI3K-Akt and stress-responsive pathways. This context-dependent activity enables FOXOs to act as dual regulators: brief activation improves proteostasis, oxidative stress tolerance, and synaptic resilience, whereas dysregulated signaling triggers pro-apoptotic and neurodegenerative pathways. Genetic and pharmacological studies targeting FOXO signaling highlight its potential as a therapeutic target; nonetheless, obstacles persist, including isoform specificity, compensatory feedback mechanisms, and transport across the blood-brain barrier. This review consolidates contemporary understanding of the structural and functional functions of FOXO isoforms in AD, their participation in amyloid and tau pathology, oxidative stress, and neuroinflammation, and assesses options for therapeutic control. A deeper understanding of FOXO signaling could lead to novel therapies that utilize its neuroprotective properties specifically, while minimizing adverse effects.",
"42189938": "ID: 42189938\nTitle: Vagal activation inhibits insulin release through neuronal nitric oxide synthase in obese male mice.\nAbstract: The vagus nerve connects the brain and pancreas and enhances postprandial endocrine secretion from the pancreas through cholinergic signaling, such as increasing insulin release immediately after food intake in the cephalic-phase insulin response (CPIR). Here, we investigated how obesity affects vagal regulation of pancreatic endocrine function using designer receptors exclusively activated by designer drugs (DREADDs) to manipulate vagal activity. As expected, the plasma concentration of insulin was increased by vagal activation in mice expressing the excitatory DREADD hM3Dq (M3 mice) and decreased by vagal inactivation in mice expressing inhibitory DREADD hM4Di (M4 mice). However, vagal activation in M3 mice with diet-induced obesity did not elicit an early increase in insulin and instead produced a delayed insulin decrease. Mathematical modeling showed that plasma insulin dynamics in these mice were best explained by a model incorporating both the insulin-increasing and insulin-decreasing effects of the vagus nerve. Furthermore, the insulin-decreasing effect was mediated by nitric oxide (NO)-dependent, noncholinergic signaling and was enhanced in obesity. In obese M3 mice, vagal deficiency of neuronal NO synthase (nNOS) abolished the insulin-decreasing effect and restored insulin release after vagal activation. Vagal nNOS deficiency also enhanced insulin release after voluntary feeding, consistent with the CPIR. These findings suggest that vagal NO action inhibits postprandial insulin release, particularly in obesity.",

Their secretome exerts cytoprotective effects in the brain, although the mechanisms underlying MSC-mediated neurological recovery remain poorly understood. A substantial portion of the MSC secretome is delivered via extracellular vesicles (EVs), membrane-bound particles that facilitate intercellular communication. EVs derived from MSCs of various origins exhibit therapeutic potential, and numerous studies are examining the miRNA and protein cargo contained within MSC-EVs. Despite these efforts, methodological differences across the literature and the inherent variability associated with MSC sources have limited data interpretation and identification of EV-factors which may be responsible for neuroprotection. In this study, we have reviewed proteomic, transcriptomic and lipidomic datasets from a selection of recent MSC-EV studies, to identify shared cargo components that may contribute to promoting cell repair and plasticity in brain, counteracting neurodegeneration.",

This study investigated whether Elaeagnus angustifolia polysaccharide (EAP) is associated with protection against HFFD-induced cognitive decline by modulating this axis. Male C57BL/6J mice (n = 15/group) received Control, HFFD, HFFD + LEAP (300 mg/kg/day EAP), or HFFD + HEAP (800 mg/kg/day EAP) for 14 weeks. HEAP improved spatial memory, reducing escape latency by 31.2% on day 5 (p < 0.01). Multi-omics and histopathological analyses revealed that EAP was dose-dependently associated with restructuring of the gut microbiota, expanding Muribaculaceae and other SCFA-producers while suppressing pathobionts, thereby reversing the Firmicutes/Bacteroidota ratio from 1.71 to 0.94 (p < 0.01). Elevated cecal, hepatic, and cerebral acetate, propionate, and butyrate (p < 0.01) were associated with improved intestinal barrier integrity, attenuated systemic LPS translocation, and reduced hepatic inflammation and changes consistent with normalization toward control levels of PPAR\u03b1/\u03b3 signaling. These peripheral improvements were accompanied by changes in the hippocampus, where EAP suppressed IBA-1 microglial activation (from 4.5-fold to 2.1-fold of control, p < 0.01) and IL-6/TNF-\u03b1 signaling, changes in neurotransmitter balance (Glu, 5-HT, DA), and preserved postsynaptic density ultrastructure and PSD-95 expression (p < 0.01). These findings support a role for EAP in modulating the gut-liver-brain axis and may help prevent diet-related cognitive impairment, supporting its development as a microbiome-targeted functional food ingredient.",

In this study, we investigated the dynamics, diversity, and persistence of 25 S. thermophilus phages isolated over a 15-year period from a large yogurt manufacturing plant. Phages were classified into Moineauvirus (16) and Brussowvirus (9), comprising ten distinct restriction profiles. Host range, genomic features, and resistance to thermal and chemical treatments were analyzed to identify factors underlying their long-term persistence. No significant differences in thermal resistance between the two groups were observed at 63\u00a0\u00b0C (30\u00a0min), 72\u00a0\u00b0C (5\u00a0min), or 90\u00a0\u00b0C (5\u00a0min). However, Brussowvirus phages exhibited greater stability during storage at 25\u00a0\u00b0C and 8\u00a0\u00b0C over eight months and tolerated sodium hypochlorite concentrations up to 500\u00a0ppm. All phages were effectively inactivated by 2.0% Lysoform\u2122, below the manufacturer's recommended concentration (2.8%). Most phages displayed at least one resistance trait, contributing to their persistence in industrial environments. Genomic analysis revealed double-stranded DNA genomes ranging from 33.2 to 39.8\u00a0kb, encoding 40-58 predicted ORFs. Several phages carried genes coding for anti-CRISPR proteins (AcrIIA3, AcrIIA5, AcrIIA6, AcrIIA21, AcrIIA25, and truncated AcrIIA36), enabling evasion of the main defense systems in S. thermophilus. Notably, infectivity was not always linked to Acr presence or protospacer matches, indicating alternative bacterial resistance mechanisms. These findings underscore the complexity of phage-host interactions and highlight the need for continuous monitoring and improved control strategies in dairy processing environments.",

Dipeptidyl peptidase-4 (DPP-4), an enzyme primarily known for inactivating incretin hormones like glucagon-like peptide-1 (GLP-1), is now recognized as a critical link between metabolic dysfunction and gut microbiome dysbiosis. This review aims to examine the mechanistic role of DPP-4 and its inhibitors in obesity, specifically focusing on how they modulate the gut microbiome to influence host energy balance and metabolic health. Recent experimental and clinical evidence indicates that DPP-4 activity contributes to obesity by influencing microbial composition, diversity, and function. Studies demonstrate that DPP-4 inhibitors can reshape the gut microbiota by reducing dysbiosis, decreasing the Firmicutes-to-Bacteroidetes ratio, and enhancing the production of short-chain fatty acids (SCFAs). Furthermore, these inhibitors improve gut barrier integrity and regulate bile acid metabolism, which helps attenuate systemic inflammation and restore insulin sensitivity. While DPP-4 inhibitors are often weight-neutral in clinical settings, they appear to assist in maintaining metabolic stability by enhancing central satiety signaling and reducing neuroinflammation. The gut microbiome acts as a key intermediary in the metabolic regulation managed by DPP-4. By restoring microbial balance and promoting beneficial metabolites, DPP-4 inhibitors offer therapeutic advantages that extend beyond traditional glycemic control to include improved energy equilibrium and reduced adiposity. Targeting the interactions between DPP-4 and the microbiota represents a promising future therapeutic strategy for managing obesity and its associated metabolic complications.",

The mTOR pathway is a central driver of aging-related diseases, such as cancer, chronic inflammation and neurodegeneration; pharmacological inhibition with rapamycin is associated with reduced aged-related morbidity and increased lifespan across species. Nonetheless, concerns remain about the use of rapamycin, a well-established immunosuppressant in transplant medicine, as an anti-aging intervention. Here, we evaluated the impact of prolonged low-dose dietary rapamycin on the aging immune system. Treatment did not significantly alter innate or adaptive immune cell populations, including brain resident microglia; however, it attenuated the age-associated accumulation of IL-17-producing \u03b3\u03b4 T cells, particularly in the peritoneal cavity. After a peripheral inflammatory LPS challenge, circulating IL-17 levels were significantly reduced and correlated with an attenuation of microglia inflammatory phenotype.

However, the adoption of plant-based alternatives depends on multiple factors, including consumer preferences, sensory quality, product affordability, and availability, in addition to sustainability and ethical considerations. Although nondairy yogurt alternatives may offer environmental advantages over conventional dairy products, their broader adoption is often constrained by textural limitations, which remain a major barrier to consumer acceptance. Addressing texture deficiencies requires strategic ingredient selection and optimized processing techniques. While existing literature focuses primarily on plant-based systems, alternative protein sources such as fungal proteins remain underexplored, with few studies evaluating fungal protein-based yogurt analogues. This review summarizes recent advances in improving the texture of nondairy yogurt alternatives, with particular attention to in situ dextran synthesis during fermentation as a natural biothickening strategy. Compared with many heteropolysaccharides often produced at relatively low yields by yogurt starters, dextran, a homopolysaccharide, can be synthesized at higher levels by certain lactic acid bacteria (LAB) and contributes to enhanced viscosity and gel formation in plant-based matrices. We discuss the mechanisms underlying these effects, including dextran-protein interactions and water-binding capacity, as well as their relevance to clean-label and functional food trends. Key research priorities include identifying food-grade, high-yield dextran-producing LAB strains, assessing their safety and allergenicity, and investigating the digestive fate and health effects of in situ-produced dextrans. Overall, in situ dextran production represents a promising strategy for improving the texture and consumer acceptance of nondairy yogurt alternatives.",

Ergothioneine (EGT), a natural dietary sulfur-containing amino acid, possesses potent antioxidant properties. This study investigates the neuroprotective potential of EGT in experimental ischemic stroke and elucidates its underlying molecular signaling pathway. Two ischemic stroke models, the photochemical ischemia model and the middle cerebral artery occlusion (MCAO) model, were established to evaluate the neuroprotective effects of EGT. 2,3,5-Triphenyltetrazolium chloride staining was performed to assess infarct volume, and laser speckle contrast imaging was used to monitor cerebral blood flow. Immunofluorescence was employed to detect the activation of astrocytes and microglia. Proteins involved in the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway were analyzed by Western blot to explore the underlying mechanism of EGT. In both photochemical ischemia and middle cerebral artery occlusion models, EGT significantly reduced infarct volume, improved cerebral perfusion and attenuated glial cells activation. Mechanistically, EGT promoted PI3K/Akt phosphorylation, reduced cytoplasmic Kelch-like erythroid cell-derived homology-associated protein 1 expression, and enhanced nuclear Nrf2 translocation. Notably, PI3K inhibitor, LY294002, completely abolished the neuroprotective effects of EGT. EGT exhibits significant neuroprotection against experimental ischemic stroke by mitigating oxidative stress and neuroinflammation, and its efficacy is critically dependent on the activation of the PI3K/Akt/Nrf2 signaling pathway.",

However, it is unclear whether exercise-induced gut microbiota remodeling causally contributes to the neuroprotective effects of exercise in AD. Herein, APP/PS1 mice underwent 12\u00a0weeks of treadmill exercise, and fecal microbiota transplantation (FMT) was used to determine whether exercise-related benefits could be transferred to the recipient mice. Behavioral performance was assessed using the Morris water maze and open-field test. Gut microbial profiles were analyzed by 16S rDNA sequencing. Intestinal barrier integrity was evaluated using histology, AB-PAS staining, and tight-junction protein expression, while plasma and brain LPS levels were measured by enzyme-linked immunosorbent assay. Neuroinflammation was examined with immunofluorescence and Western blotting. It was found that treadmill exercise improved spatial learning, memory, and anxiety-like behavior in APP/PS1 mice. These benefits were partly reproduced in recipients of microbiota from exercised donors. Exercise also restored gut microbial diversity and composition, increased the abundance of taxa including Dubosiella and UBA1819, alleviated colonic injury, enhanced mucus secretion, upregulated ZO-1, Occludin, and Claudin-1, and reduced plasma and brain LPS levels. In parallel, exercise and FMT from exercised donors decreased brain TLR4 expression, attenuated microglial and astrocytic activation, and suppressed TLR4/NF-\u03baB signaling and downstream inflammatory cytokines. These findings indicate that treadmill exercise alleviates neuroinflammation in APP/PS1 mice, at least in part, through gut microbiota remodeling, improved intestinal barrier integrity, and reduced LPS-driven inflammatory signaling.",
"42223207": "ID: 42223207\nTitle: Energy Stress-Induced Neuroprotection Against Ferroptosis in Dopaminergic Neurons.\nAbstract: Ferroptosis, an iron-dependent form of regulated necrosis, is implicated in the pathogenesis of Parkinson's disease (PD). We studied the influence of energy stress on ferroptosis in differentiated dopaminergic neurons (LUHMES). Glucose deprivation conferred protection against ferroptosis induced by erastin or arachidonic acid plus iron by reducing lipid peroxidation. Glucose withdrawal did not protect against RSL3-induced ferroptosis, suggesting that direct GPX4 inhibition cannot be reversed by metabolic modulation. The expression of ferroptosis markers ACSL4, GPX4, xCT, and TFRc remained unaltered during glucose deprivation. Inhibition of glycolysis using 2-deoxyglucose confirmed the role of energy stress in the regulation of ferroptosis. Activation of AMP-activated protein kinase (AMPK) by AICAR protected LUHMES cells from erastin-induced ferroptosis, even in the presence of glucose. Conversely, AMPK expression inhibition by siRNA re-sensitized cells to ferroptosis under glucose-free conditions. These findings suggest that glucose metabolism and AMPK-mediated energetic stress play crucial roles in regulating ferroptosis in dopaminergic neurons, with potential implications for understanding the mechanisms of neurodegeneration in PD. These findings identify a potential bioenergetic checkpoint regulating ferroptosis susceptibility under conditions of severe energy stress.",

This investigates the influence of floral origin on the fermentation performance, chemical composition, and antioxidant properties of meads. Five honey samples, including monofloral and polyfloral types, were characterised via melissopalynological analysis and fermented in 3\u00a0L glass bioreactors using S. cerevisiae (4.5\u00a0\u00d7\u00a0105 cells/mL) at 20\u00a0\u00b0C for 24\u00a0days. Honey quality was assessed through physicochemical parameters, sugar profiles, and colour, while meads were analysed for phenolic compounds, sugars, organic acids, and alcohols using HPLC. Antioxidant activity was evaluated using DPPH, ABTS, and FRAP assays. Floral origin influenced fermentation kinetics, yeast viability, and the bioactive composition of meads. Monofloral M1 (jurema-preta) and M5 (mal\u00edcia) yielded meads with the highest phenolic and antioxidant potential, whereas M2 (polyfloral) achieved superior ethanol content. The findings paves the way for developing alcoholic beverages using Caatinga honeys.",

This study aims to investigate whether fat mass and obesity-associated protein (FTO) exacerbate ICH-induced brain injury by regulating autophagy-dependent ferroptosis and to identify potential therapeutic targets. An ICH model was established in rats via autologous blood injection. FTO expression was knocked down using adeno-associated virus-delivered short hairpin RNA (shRNA). Neurological scores, brain edema, and histopathology were assessed. Autophagy, oxidative stress, and ferroptosis markers were measured by Western blot and enzyme-linked immunosorbent assay (ELISA).Immunofluorescence was performed for FTO with neuronal nuclei (NeuN), glial fibrillary acidic protein (GFAP), ionized calcium-binding adapter molecule 1 (Iba-1), LC3, and GPX4/microtubule-associated protein 2 (MAP2). FTO expression was significantly upregulated post-ICH, correlating with neurological deterioration, cerebral edema, neuronal loss, and inflammatory infiltration. Immunofluorescence showed FTO colocalized with NeuN. FTO knockdown attenuated neurological deficits, reduced cerebral edema, and suppressed neuronal loss. FTO knockdown inhibited autophagy-related protein (ATG5)/microtubule-associated protein 1 light chain 3B (LC3B)-mediated autophagy activation, thereby mitigating iron overload, lipid peroxidation, and ferroptosis markers (decreased glutathione peroxidase 4 [GPX4], elevated acyl-CoA synthetase long-chain family member 4 [ACSL4], and cyclooxygenase-2 [COX2]). FTO knockdown also reduced LC3 fluorescence and restored GPX4/MAP2 colocalization. Rescue experiments further confirmed that ATG5 overexpression reversed the neuroprotective effects of FTO knockdown. FTO aggravates ICH-induced brain injury by promoting ATG5/LC3B-mediated autophagy and subsequent ferroptosis. Targeting FTO represents a promising therapeutic strategy to mitigate secondary brain damage post-ICH.",

Tanshinones, a class of lipophilic diterpenoid quinones derived from Salvia miltiorrhiza (Danshen), have attracted increasing attention as multi-target neuroprotective agents in experimental models of cerebral I/R. Accumulating evidence demonstrates that major tanshinones, including tanshinone I, tanshinone IIA, tanshinone IIB, cryptotanshinone, and dihydrotanshinone I, modulate key neurochemical processes underlying cerebral I/R injury, including redox homeostasis, inflammatory signaling cascades, mitochondrial function, BBB integrity, and cell death regulatory networks. In parallel, recent advances in formulation strategies, including chemically modified derivatives (e.g., sodium tanshinone IIA sulfonate and the cryptotanshinone derivative DST-3), as well as microemulsions, liposomes, and nanoparticle-based delivery systems, have markedly improved aqueous solubility, pharmacokinetic behavior, and brain bioavailability of tanshinones, thereby potentially enhancing their neuroprotective effects in experimental models. This review comprehensively summarizes current evidence on the neurochemical and molecular mechanisms of tanshinones and their formulations in cerebral I/R injury, with an emphasis on signaling pathway modulation, redox regulation, mitochondrial protection, and formulation-driven improvements in brain delivery, and discusses remaining mechanistic challenges and future research directions.",

To understand mediators of cagrilintide action, we generated a transcriptomics atlas of over 530,000 cells comprising 80 neuronal cell populations across rat, mouse and macaque caudal brainstem, with spatial profiling to map distribution in the rat dorsal vagal complex (DVC). Here we show that cagrilintide regulates two conserved Calcr-expressing DVC neuronal populations. While acute cagrilintide treatment alters gene expression in area postrema Calcr/Ramp3 neurons, chemogenetic activation in rats fails to affect long-term food intake and body weight. In contrast, long-term cagrilintide treatment in rats upregulates prolactin-releasing hormone (Prlh) expression in nucleus of the solitary tract Calcr/Prlh cells that are conserved across rodents, macaques and humans. Knocking down DVC Prlh abrogates the effects of cagrilintide but not semaglutide in rats. Our study provides a cross-species spatially resolved atlas of DVC cell populations and defines Calcr/Prlh neurons as mediators of amylin receptor agonist action.",

The aim of the study was to isolate Lactobacillus strains that produce EPS from dairy sources and to enhance EPS production. The dairy source milk, yogurt, and cheese were collected from the local market for isolation of EPS producing strain. The maximum EPS-producing strain was further identified based on biochemical, morphological, and 16S RNA sequencing. Whey was used as a substrate due to its low cost and nutrient- rich composition. Different organic and inorganic nitrogen sources were screened. Central Composite Design (CCD) of Response Surface Methodology (RSM) was used for the optimization of physiochemical parameters. Five various physio-chemical parameters i.e. pH, temperature, nitrogen source, substrate concentration, and incubation period, were optimised. The process was subsequently upscaled in a 1.5\u00a0L lab scale bioreactor. Among these, the isolate obtained from cheese exhibited the highest EPS yield. The isolated strain was identified as Limosilactobacillus fermentum-CP158463.1. The yeast extract was found to be the best source of nitrogen 1.7\u00a0\u00b1\u00a00.15\u00a0mg/ml of EPS yield. The optimal conditions for maximum EPS (2.729\u00a0mg/mL) were observed at pH\u00a08, 40\u00a0\u00b0C, 1% nitrogen concentration, 20% substrate concentration, and a 48-h incubation time. The maximum yield (8.396\u00a0\u00b1\u00a01.73\u00a0mg/ml) was obtained at 200\u00a0rpm with 96\u00a0h incubation period. The study shows that Lactobacillus originating from dairy has the capacity to produce EPS, and the RSM model can be used for effective low-cost production.",
"42266250": "ID: 42266250\nTitle: The kynurenine pathway: an immunometabolic bridge linking systemic inflammation to neuroaxonal vulnerability in multiple sclerosis.\nAbstract: Multiple sclerosis (MS) extends beyond focal autoimmune demyelination, with progressive neurodegeneration and cognitive impairment arising from mechanisms not fully explained by inflammatory lesions alone. We propose the kynurenine pathway (KP) as a unifying immunometabolic interface that translates peripheral inflammation into central neuroaxonal vulnerability. Cytokine-driven induction of indoleamine 2,3-dioxygenase accelerates systemic tryptophan catabolism, increasing circulating kynurenine that crosses the blood-brain barrier via L-type amino acid transporter 1 (LAT1). Within the CNS, microglial kynurenine 3-monooxygenase generates the excitotoxic and pro-oxidant metabolites quinolinic acid and 3-hydroxykynurenine, while astrocytic kynurenine aminotransferases produce the neuroprotective antagonist kynurenic acid. This enzymatic dichotomy creates a dynamic amplification loop that intensifies excitotoxicity, oxidative stress, oligodendrocyte injury, and axonal loss. Clinical evidence shows that kynurenine metabolite ratios correlate with plasma neurofilament light chain, cognitive deficits, obesity-related inflammation, and phenotype-specific exercise responsiveness, underscoring KP plasticity as a potential determinant of disease trajectory. By reframing MS through this immunometabolic lens, the KP emerges as both a mechanistic bridge between inflammation and neurodegeneration and a tractable biomarker system with therapeutic potential.",

Beyond its systemic role in mineral metabolism and oxidative stress regulation, emerging evidence highlights its critical involvement in maintaining cognitive function and protecting against neurodegenerative processes. This review explores the multifaceted role of \u03b1-Klotho in the central nervous system, emphasizing its physiological functions, underlying molecular mechanisms, and therapeutic potential. \u03b1-Klotho exerts neuroprotective effects by modulating calcium and phosphate homeostasis, attenuating oxidative stress, and suppressing neuroinflammation. Additionally, it regulates signalling pathways such as IGF-1, Wnt/\u03b2-catenin, and Nrf2, which are essential for neuronal survival and synaptic plasticity. Reduced \u03b1-Klotho expression has been linked to cognitive impairment, Alzheimer's disease, Parkinson's disease, and other age-related neurodegenerative disorders. Preclinical studies demonstrate that enhancing \u03b1-Klotho expression or administering a recombinant protein improves learning, memory, and neuronal resilience, positioning \u03b1-Klotho as a promising therapeutic target. However, challenges such as limited blood-brain barrier penetration, stability of recombinant forms, and incomplete mechanistic understanding hinder clinical translation. Overall, \u03b1-Klotho stands as a novel biomarker and a promising intervention strategy for mitigating neurodegeneration and promoting healthy brain ageing.",

Tetramethylpyrazine (TMP) is a natural product with well-established clinical efficacy against ischemic stroke, yet its molecular target and mechanism of action remain elusive. By integrating a bifunctional photoaffinity TMP probe with stable isotope labeling by amino acids in cell culture and activity-based protein profiling (SILAC-ABPP), we identified thioredoxin 1 (Trx1) as a direct target of TMP. We demonstrate that TMP binds specifically to tyrosine 49 (Y49) on Trx1, antagonizes its nitrative modification, and functions as an allosteric activator. This binding enhances Trx1's reductase activity, strengthens its interaction with apoptosis signal-regulating kinase 1 (ASK1), and consequently suppresses the ASK1-p38/JNK signaling cascade. Genetic ablation of Trx1 or ASK1, or pharmacological induction of Trx1 nitration, completely abolishes TMP-mediated neuroprotection. Our findings not only decipher the mechanistic basis for TMP's clinical efficacy but also identify Y49 of Trx1 as a druggable allosteric site, unveiling a novel anti-nitrative therapeutic strategy for ischemic stroke and related disorders involving nitrative stress.",

This study investigated whether Jujube polysaccharides (ZJP), a food-derived polysaccharide, confer neuroprotective and anti-aging benefits in Caenorhabditis elegans. ZJP was characterized for physicochemical features, antioxidant capacity, and in vivo safety. Effects were evaluated in wild-type N2 and PD models by measuring lifespan, locomotion, pharyngeal pumping, chemotaxis, \u03b1-syn::YFP fluorescence intensity, dopaminergic neuron integrity, adenosine triphosphate (ATP), reactive oxygen species (ROS), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and lipofuscin. Stress resilience was assessed under heat (37 \u00b0C) and H2O2 exposure. RT-qPCR profiled genes related to stress responses and neurotransmission. ZJP showed no detectable toxicity at tested doses. ZJP extended mean lifespan in N2 (10.3-14.1%) and NL5901 (9.1%), improved locomotion, pharyngeal pumping, and chemotaxis, reduced lipofuscin (26.8-50.6%), and increased survival under heat (23.6%) and oxidative stress (38.1%). In PD models, ZJP reduced \u03b1-syn::YFP fluorescence by up to 54.9%, protected dopaminergic neurons, and increased ATP. It also lowered ROS and MDA levels while raising SOD and CAT activities. Gene expression changes were associated with enhanced oxidative stress resistance and with altered expression of genes involved in SKN-1/DAF-16-related stress-response signaling. These findings provide preliminary evidence that ZJP may promote longevity, stress resilience, and neuroprotection in C. elegans models of PD, supporting its potential as a candidate for further investigation in neuroprotection.",

This narrative review examines the molecular cross-talk linking these pathologies, with a specific focus on the distinction between pentameric C-reactive protein (pCRP) and its proinflammatory monomeric form (mCRP). We discuss evidence suggesting that mCRP is not merely a passive marker but also an active driver of endothelial dysfunction, atherosclerosis, and synovial inflammation. This review further explores the connections among inflammatory biomarkers, blood vessel integrity, and neurodegeneration, detailing how persistent cytokine elevation (IL-6, TNF-\u03b1) and vascular injury contribute to cerebral small vessel disease (cSVD) and cognitive decline, with neurofilament light chain (NfL) serving as a key biomarker of neuroaxonal injury. Additionally, we address the neurobiology of pain in RA, highlighting the mechanisms of central sensitization (CS) and neuroimmune signalling that sustain pain-independent joint swelling. This evidence indicates that understanding the dynamic connection between CRP isoforms and neuronal markers should offer new insights for risk stratification and suggests that targeting mCRP may provide a novel therapeutic avenue to mitigate both articular and extra-articular manifestations of RA.",

Here, untargeted GC-MS metabolomics was used to investigate the effects of standardized Brazilian green propolis on the striatal metabolic profile in the 6-hydroxydopamine (6-OHDA) rat model. Discriminant metabolites, including suberic acid, gluconic acid, heptadecane, and tartaric acid, distinguished experimental groups, capturing key features of the metabolic response to dopaminergic injury and treatment. Suberic acid emerged as a prominently modulated metabolite, potentially linked to alterations in lipid catabolism associated with mitochondrial-peroxisomal pathways. Propolis treatment attenuated the elevation of suberic acid, accompanied by a reduction in gluconic acid levels, suggesting a metabolic profile linked to pathways involved in redox balance and glucose handling. Given previous reports identifying heptadecane as a hydrocarbon constituent of volatile propolis fractions, complementary GC-Q-TOF analyses demonstrated that heptadecane was absent from the administered extract, despite its consistent association with propolis-treated groups. Metabolic changes were accompanied by attenuation of nigrostriatal dopaminergic neurodegeneration and improved motor performance. Together, these findings delineate a striatal metabolic signature associated with Brazilian green propolis and identify suberic acid as a key metabolite linked to neuroprotection in experimental Parkinsonism.",
"42281745": "ID: 42281745\nTitle: The Intestinal Barrier: A Multilayered Gatekeeper Against Systemic Disease.\nAbstract: The intestine performs two distinct yet seemingly contradictory functions: the digestion and absorption of nutrients, and the defense against harmful substances and pathogens. The intestinal barrier is a multilayered system maintained by four key components: the physical, chemical, microbiological, and immunological barriers. Each layer plays a unique role in preventing the translocation of harmful entities from the intestinal lumen into the body. Disruption of this integrated barrier increases intestinal permeability, a condition commonly referred to as \"leaky gut,\" in which harmful substances and pathogens can enter the systemic circulation. We also highlight that barrier dysfunction differs between the small and large intestines, reflecting regional differences in epithelial structure, mucus architecture, and microbial load. Growing evidence indicates that such barrier disruption triggers cascades of inflammatory responses in various organs, including the liver, brain, muscles, and kidneys, leading to impaired physiological functions. This review delineates the four layers of the intestinal barrier and explores the systemic consequences of its disruption. In addition, it summarizes current approaches for assessing intestinal barrier function and discusses the strengths and limitations of widely used experimental models. The review also outlines current therapeutic strategies for barrier restoration, including dietary interventions, microbiota-directed approaches, postbiotics, bile acid modulators, anti-inflammatory and immunomodulatory therapies, and lifestyle modification. A deeper understanding of this multilayered gatekeeper is essential for developing novel preventive and therapeutic strategies aimed at restoring barrier integrity and strengthening the defense against a wide range of systemic diseases.",

This study examined the impact of three probiotic combinations-Y1 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus rhamnosus), Y2 (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus and Lactobacillus paracasei) and Y3 (Lactobacillus plantarum and Bifidobacterium sps.)- on microbial dynamics and metabolite formation in lupin-oat yoghurt analogues, using unfermented milk analogues as a control. Samples were assessed during fermentation and throughout 28 days of refrigerated storage (4 \u00b0C) using microbial enumeration, 16S rRNA sequencing, acidification profiling, and mass spectroscopy-based metabolomics. Fermentation increased volatile compounds, from 23 in the control to 28 (Y1), 41 (Y2) and 54 (Y3). Probiotic combination Y3 exhibited the most complex and stable aroma profile, enriched in pleasant volatiles such as butanoic acid, phenylacetaldehyde, and butyl esters which effectively masked off-flavours like hexanal and heptanal. Microbiota analysis revealed stable formulation-specific communities, with- Streptococcus dominating in yoghurt analogues Y1 and Y2, and Bifidobacterium prevailing in yoghurt analogues Y3. KEGG-based functional prediction linked these transformations to microbial enzymatic activities within metabolic pathways. Notably, Bifidobacterium dominance in Y3 facilitated enhanced ester biosynthesis and conversion of aldehydes to acids, highlighting the \"bifid shunt\" as a key contributor to flavour enhancement. This integrated multi-omics approach highlights the critical role of targeted probiotic selection in modulating fermentation biochemistry, microbial ecology, and sensory attributes in plant-based lupin-oat yoghurt analogues.

This review examines emerging evidence that the gut microbiome plays a more active and specific role in this process than previously appreciated. Dysbiosis during critical illness directly contributes to barrier dysfunction through depletion of metabolites that sustain epithelial integrity. Culture-independent approaches have revealed that gut-derived organisms are a major reservoir for secondary infection, with translocation governed by microbial virulence, community dynamics, and immune cell-mediated transport rather than barrier permeability alone. In parallel, organism-specific microbial components - including structurally diverse forms of lipopolysaccharide and bacterial DNA detected across multiple blood fractions - enter the circulation and differentially modulate host immune responses. Recent studies link circulating microbial DNA composition to distinct inflammatory phenotypes in sepsis and acute respiratory distress syndrome, suggesting these signals contribute to clinical heterogeneity. These findings support a revised framework in which translocation reflects the composition of the dysbiotic gut, not barrier integrity alone. Integrating microbial data with host phenotyping may enable more precise risk stratification and microbiome-informed therapeutic strategies in critical illness.",

Importantly, this review emphasizes the translational relevance of microbiome-targeted interventions, including prebiotics, probiotics, synbiotics, and emerging postbiotic strategies, in modulating disease progression and therapeutic outcomes. Although limitations lies in correlating the human gut microbiota to the results obtained from the animal studies which may not fully reflect the physiological conditions of the human gut as it is affected by several factors, this work provides a unified framework linking gut microbiota, immune regulation, and disease pathogenesis, and outlines future directions for the development of targeted and personalized microbiome-based therapies which may be achieved through well designed longitudinal and large scale clinical studies further.",

The ICH-induced neurological deficits were analyzed by behavioral studies including Zea-Longa score, Neurological Severity Score, Open filed test, Y-maze test, Morris water maze, Rotarod test and pathological staining such as HE staining and Nissl staining. Perls staining was used to measure iron deposition after ICH. Malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) assay kits were performed to measure the level of lipid peroxide after ICH. The levels of oxidative stress-related targets were verified by quantitative real-time PCR and western blot.\u00a0This study demonstrated that ZL capsule treatment significantly reduced ICH-induced neurological deficits after ICH, improved the memory learning functions of rats and attenuated ICH\u2011Induced neuron damage in rats. After ICH, oxidative stress in brain tissue increased and ZL capsule could alleviate the pathological state of oxidative stress. The SOD and GSH activities were dramatically increased after the treatment of ZL capsule compared with the Ns group, while the content of MDA was markedly decreased after treatment with ZL capsule compared with Ns group. After ICH, the SLC40A1, SLC7A11, SESN2 and GPX4 mRNA in brain tissue increased, and the NOX4 and TFR1 mRNA in brain tissue decreased after the treatment of ZL capsule. Proteomics analysis also confirmed these results.\u00a0Our data suggested that ZL capsule showed a neuroprotective function after ICH and alleviated ICH induced neurological deficits in rats. The possible mechanism may be that ZL capsule inhibits iron deposition and lipid peroxidation, lessening oxidative stress in brain tissue.

"42311683": "ID: 42311683\nTitle: Gut microbiota modulation in the prevention and treatment of heat stroke.\nAbstract: In recent years, heat stroke (HS) have been reported with increasing frequency, and this trend is hard to separate from broader environmental changes, including climate change, recurrent extreme heat events, and air pollution. When people are exposed to high-temperature environments for a prolonged period, especially during intense physical activity, the condition may progress to HS. HS is an acute and potentially fatal disorder that can deteriorate rapidly if not treated in time. The intestine appears to be particularly vulnerable during HS. HS can disrupt intestinal tight junctions and weaken the barrier function of the gut, leading to what is commonly described as a \"leaky gut.\" Once this barrier is compromised, microbial products such as lipopolysaccharides can enter the bloodstream. These molecules may then activate immune cells, promote excessive cytokine release, and eventually drive a systemic inflammatory response. In severe cases, this inflammatory process can develop into systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Current evidence increasingly suggests that intestinal injury is not simply a secondary result of HS. Rather, it may serve as an important early event in the development and progression of the disease. Still, it should be noted that much of the available evidence comes from preclinical studies, and strong clinical confirmation is still limited. Probiotics have attracted attention because they may help reduce the occurrence and severity of HS by maintaining gut microbiota balance and regulating intestinal immune responses. However, since most supporting data are still derived from animal experiments, their protective effects in humans need to be interpreted carefully. Another point worth emphasizing is that the gut is not working alone. Through gut-organ communication networks, the intestinal microbiota can interact with distant organs, including the liver, lungs, and brain. These gut-liver, gut-lung, and gut-brain axes may help explain how HS leads to injury beyond the intestine itself. In this review, we summarize current findings on how modulation of the gut microbiota may improve intestinal thermotolerance and strengthen barrier function, with the aim of providing useful insights for the prevention and treatment of HS in clinical practice.",

UPF intake could promote systemic inflammation, oxidative stress phenomena, and metabolic dysregulation, contributing to neurodegeneration onset and cognitive decline in elderly population. The aim of this cross-sectional study was to examine the relation between UPF dietary pattern on MCI status in elderly patients taking into account the contribution of inflammatory markers. The dietary intake was assessed using a validated food frequency questionnaire in ninety-two participants. All reported food items were categorized according to the NOVA system, classifying foods on the basis of the extent and purpose of industrial processing. Plasmatic concentrations of TGF-\u03b21 and TNF-\u0251 were measured by ELISA assay at the time of baseline neuropsychological evaluation. The Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) were administered to evaluate the cognitive function in all participants. Non-parametric tests, correlation analysis, and logistic regression models were performed to assess the relations between variables of interest. No significant associations were observed for unprocessed/minimally processed foods, culinary processed foods, or processed foods across the different regression models. In contrast, higher consumption of UPF was associated with increased odds of MCI (adjusted OR\u202f=\u202f4.24, 95% CI: 1.05-17.13).

Here, we systematically profiled commercially available tetracyclines and show that translation attenuation is a general property of the tetracycline class. Importantly, we identify the atypical tetracyclines 4-epiminocycline and 12-aminominocycline, which attenuate translation independently of antibiotic activity and integrated stress response (ISR) activation. These compounds extend lifespan in C. elegans, attenuate translation in human induced neurons, reduce hippocampal protein synthesis in\u00a0vivo, and protect neurons from ferroptotic stress.

At the same time, increasing attention has been directed toward digestion-driven nutritional functionality, calling for a renewed, digestion-oriented interpretation of processing-induced protein modifications and their downstream physiological relevance. The review synthesizes current knowledge on how key yogurt processing technologies-standardization, homogenization, heat treatment, and fermentation-govern milk protein structural transformations, gel network formation, and bioactive peptide generation. Particular emphasis is placed on linking processing-induced protein changes with gastrointestinal digestion behaviors, including gastric emptying, enzymatic hydrolysis, and nutrient absorption. Precisely, processing-driven protein denaturation, aggregation, redistribution, and hydrolysis collectively determine yogurt matrix architecture and its digestive fate. Structural features of the yogurt matrix modulate gastric emptying kinetics, whereas protein conformational changes influence enzymatic accessibility and hydrolysis rates. Fermentation-associated proteolysis further alters the profile and availability of absorbable peptides and amino acids. This review may help for advancing yogurt production from standardized processing toward precision nutrition design and for developing functional yogurts with targeted digestive and health benefits.",

PD is a chronic neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc), driven by a complex interplay of mitochondrial dysfunction, oxidative stress, and neuroinflammation. While basal MAPK activity is essential for neuroprotection and neuronal growth, its overactivation, specifically via the JNK and p38 cascades, accelerates neurodegeneration. This review explores the molecular landscape of MAPK signaling, detailing how its dysregulation promotes the accumulation of alpha-synuclein and the activation of microglia. Furthermore, it highlights critical crosstalk between MAPK and other vital pathways, including the inhibition of the neuroprotective PI3K/AKT and PP2A pathways and the detrimental activation of GSK-3\u03b2 and PTEN signaling. Preclinical evidence strongly supports the use of MAPK inhibitors to mitigate dopaminergic neurotoxicity and reduce proinflammatory cytokine release. Despite promising results in experimental models and the development of highly selective inhibitors, clinical translation remains challenging due to potential systemic toxicities. This manuscript provides a comprehensive synthesis of mounting and mooting evidence, positioning MAPK inhibition as a potent, albeit complex, adjuvant strategy for delaying the onset and progression of PD neuropathology.",

To overcome these supply and bioavailability constraints, we developed a metabolically engineered rice variety, DJ-PPD, capable of directly biosynthesizing the aglycone PPD. This study investigated the anti-inflammatory and antioxidant mechanisms of DJ-PPD extract in lipopolysaccharide (LPS)-stimulated BV2 cells. DJ-PPD treatment significantly reduced nitric oxide (NO) production, pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and the expression of iNOS and COX-2. Its efficacy surpassed conventional ginseng extract and was comparable to synthetic PPD (S-PPD). Mechanistically, DJ-PPD inhibited NF-\u03baB, MAPKs, and Akt phosphorylation while activating the NRF2/HO-1 antioxidant pathway. These findings demonstrate that DJ-PPD simultaneously inhibits pro-inflammatory cascades and reinforces intrinsic antioxidant defences. By effectively bypassing the need for gut microbiota metabolism, this genetically engineered rice represents a sustainable, bioavailable, and commercially viable multi-target therapeutic candidate for neuroinflammatory conditions.",
"42325748": "ID: 42325748\nTitle: Perioperative gut microbiota homeostasis and its interactions with anesthetic agents: recent advances.\nAbstract: The perioperative period is a critical and acute phase during which host-microbiota interactions play an essential role in determining susceptibility to anesthetic exposure and post-surgical stress. Immune homeostasis, gut barrier integrity, and metabolic regulation, as well as gut-brain and gut-liver axis, are highly dependent on the gut microbiota. However, this microbial ecosystem is disrupted during the perioperative period due to the combined effects of fasting, bowel preparation, surgical stress, hemodynamic alterations, and antibiotic and opioid use. Growing evidence has linked perioperative dysbiosis to a wide range of adverse outcomes, including infectious complications, anastomotic leakage, postoperative ileus, organ dysfunction, and perioperative neurocognitive disorders. Meanwhile, anesthetic and analgesic agents do not act in isolation from this ecosystem; rather, they engage in a bidirectional chemical interaction with the microbiota. These interactions can alter microbial structure and metabolite profiles, thereby influencing host metabolic processes, while microbial activity, in turn, affects drug disposition, immune response, and neuroinflammation. In this review, we first describe the vulnerability of gut microbiota homeostasis during the perioperative period and its associated clinical consequences. We subsequently elaborate on the mechanistic framework of anesthetic-microbiota crosstalk, highlighting pathways involving vascular, epithelial, immune and neural signaling. Then, we summarize emerging evidence demonstrating that different anesthetic and analgesic regimens generate discrete microbiota-metabolite signatures, which may underlie intersubject differences in postoperative recovery trajectories. Finally, we describe perioperative microbiota-targeted strategies, including probiotics and synbiotics, postbiotics and microbial consortia, nutritional optimization, and microbiome-based customization of anesthetic and analgesic protocols. Collectively, existing data suggest that preserving and actively modulating gut microbiota homeostasis represents a promising yet underexplored strategy for improving the safety of anesthesia and postoperative outcomes.",

Increasing evidence suggests a potential association between these two diseases, with chronic oral infection and systemic inflammation emerging as key linking mechanisms. Periodontitis is characterized by a dysbiotic oral microbiome and persistent inflammatory responses that can lead to the dissemination of periodontal pathogens and their virulence factors into the systemic circulation. Notably, some studies have reported the detection of pathogens such as Porphyromonas gingivalis and their toxic products in the brains of individuals with AD, implicating a possible role in neuroinflammation and neurodegeneration. However, it should be clarified that detection does not establish causation. This narrative review aims to synthesize the existing evidence from animal studies exploring the link between periodontitis and AD and its related mechanisms, including neuroinflammation, amyloid and tau pathology, blood-brain barrier dysfunction, and systemic interactions. The electronic search in PubMed yielded 585 results. We focused on the past 10 years, thus removing 114 results. A total of 471 studies remained. Of the 471 articles reviewed, 239 studies were excluded based on their titles, abstracts, publication types, and topics because of inappropriate study designs (i.e., designs other than cross-sectional or animal studies). A total of 232 studies were further investigated. In this review, the analysis focused exclusively on animal studies, and the full texts were assessed against predefined eligibility criteria focusing on study design, animal model, periodontal exposure, and AD-related outcomes. Studies that met all inclusion criteria were included, whereas articles with inappropriate study designs or irrelevant outcomes were excluded. After full-text screening, 101 studies remained. Preclinical (animal) evidence supported plausible mechanistic links between periodontitis and AD. Furthermore, oral pathogens appear to mediate this ongoing neuroinflammation.",
"42334840": "ID: 42334840\nTitle: Unhealthy dietary patterns and Alzheimer's disease: associations and underlying mechanistic pathways.\nAbstract: Unhealthy dietary patterns are increasingly recognized as important modifiable factors associated with cognitive decline and Alzheimer's disease (AD). Diets characterized by high intake of saturated fats, refined sugars, and ultra-processed foods are consistently linked to metabolic dysfunction, systemic inflammation, and impaired brain health. Epidemiological and interventional studies suggest that these dietary patterns are associated with poorer cognitive outcomes, whereas adherence to nutrient-rich dietary patterns such as the Mediterranean, MIND, and DASH diets is linked to improved metabolic profiles and slower cognitive decline. Several biological mechanisms have been proposed to explain these associations, including insulin resistance, oxidative stress, neuroinflammation, vascular dysfunction, and alterations in gut-brain axis signaling; however, much of the current human evidence remains observational, limiting definitive causal inference. Emerging research also indicates that individual susceptibility to diet-related AD risk may be modified by genetic background, metabolic status, and sex-specific biological factors. Despite variability in study findings, the overall body of evidence supports a biologically plausible relationship between dietary quality and key processes implicated in AD pathogenesis. Future research should prioritize long-term, biomarker-driven randomized controlled trials, alongside life-course approaches that consider early- and mid-life dietary exposures, to better clarify causal pathways and inform targeted nutritional strategies for AD risk reduction.",
"42336160": "ID: 42336160\nTitle: YTHDF1-modified neural stem cells confer neuroprotection and promote functional recovery following traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) is a significant contributor to global morbidity and mortality, with limited effective treatment options available. Neural stem cells (NSCs) have shown great potential in the treatment of TBI. However, the relatively low differentiation rate of neurons largely hinders the therapeutic efficacy of brain tissue repair. Here, we found that following TBI, the expression level of YTHDF1 in the hippocampus significantly increased and then decreased. Previous reports have also indicated that YTHDF1 mRNA is preferentially expressed in the mouse hippocampus, a key region involved in spatial learning and memory. Subsequently, we overexpressed or knocked down YTHDF1 in NSCs, and the results demonstrated that YTHDF1 promoted NSC proliferation and neuronal differentiation. In vitro, neuronal injury was induced by H2O2, and co-cultured with YTHDF1-modified NSCs to assess neuronal cell viability, apoptosis, and oxidative stress biomarkers, including the activities of superoxide dismutase (SOD) and catalase (CAT). YTHDF1-modified NSCs significantly reduced neuronal apoptosis and lowered oxidative stress levels. The expression of YTHDF1 in the hippocampus of TBI mice could rescue sensory, motor, and cognitive deficits, promoting neuronal survival. Mechanistically, YTHDF1 may be transcriptionally regulated by MYCN, and exert neuroprotective effects through the PI3K/AKT signaling pathway.",
"42337797": "ID: 42337797\nTitle: The complement system in Alzheimer's disease: evaluating biomarker potential in a complex neuroimmune context.\nAbstract: Neuroinflammatory processes are increasingly recognised as important modulators of Alzheimer's disease (AD) progression, driving interest in immune-related biomarkers beyond classical pathological measures. Among these, the complement system has attracted attention because of its interactions with amyloid-\u03b2 (A\u03b2) and tau pathology, genetic associations with AD risk, and evidence of activation within affected brain regions. However, these biological observations do not directly translate into straightforward biomarker signals. Complement activity is highly dynamic, spans multiple activation and regulatory states, and may reflect both central and peripheral immune processes. This complexity limits interpretation when complement markers are assessed in isolation, as age, systemic inflammation, vascular comorbidity, and blood-brain barrier integrity can influence measured levels. Current evidence does not support complement-derived biomarkers as stand-alone diagnostic classifiers comparable to established amyloid, tau, and neurodegeneration (AT(N)) measures. Their independent or additive value within multimodal biomarker frameworks remains unclear, partly because of cohort heterogeneity, incomplete assay harmonisation, uncertain tissue-source attribution, and limited longitudinal validation. This review critically evaluates complement-derived measures as biologically informative markers of neuroimmune activity in AD, distinguishing biological plausibility from analytical and clinical utility. We argue that their most defensible current role is within multimodal biomarker frameworks, where they may provide context-specific information on inflammatory state rather than function as independent diagnostic, staging, or treatment-monitoring tools. Progress toward clinical application will require rigorous standardisation, mechanistic clarification, and validation across large, longitudinal, and diverse cohorts.",
"42338576": "ID: 42338576\nTitle: Exploring the gut-brain axis: dietary influences on Alzheimer's disease pathogenesis.\nAbstract: Alzheimer's disease (AD) is one of the most diagnosed neurodegenerative disorders worldwide and presents a significant challenge for both affected individuals and their caregivers. Alzheimer's disease is characterized by the accumulation of amyloid plaques and dysfunctional tau protein in the brain, along with the final development of dementia. Recently, in addition to the strongly developing ischemic etiology of AD, it is suggested that the gut and oral microbiota may also participate in the development of this disease. This involvement may stem from an unbalanced diet and the consumption of foods containing harmful chemical additives. An unhealthy diet can compromise the integrity of the gut barrier, facilitating the translocation of bacterial pathogens and leading to a pro-inflammatory T-cell response mediated by innate immune cells. This inflammatory response can disrupt systemic homeostasis and may contribute to neuroinflammation. The brain and gut interact through a complex network known as the \"gut-brain-microbiota axis,\" and emerging studies suggest that the intestinal microbiota and their metabolites may play a significant role in the pathogenesis of Alzheimer's disease. Moreover, these inflammatory mediators and microbial metabolites can reach the brain via the gut-brain axis, potentially exacerbating neurodegenerative processes. Preclinical and limited clinical evidence indicates that low-fiber diets are associated with alterations in intestinal microbiota composition, which may contribute to the onset and progression of Alzheimer's disease. This review aims to explore the potential connections between AD and the gut microbiome, emphasizing the significance of dietary factors in shaping these relationships. A comprehensive understanding of the interactions between the human microbiome and the brain, particularly in the context of diet and its ingredients, may enhance our understanding of AD etiology and inform the development of preventative strategies, through dietary modifications or therapeutic interventions. This area of research holds promise for identifying novel approaches to prevent or slow the progression of AD.",

The BTB domain and CNC homolog 1 (BACH1), a transcription factor widely distributed across mammalian tissues, has been implicated in regulating diverse cellular functions. Nevertheless, its role in early brain injury after SAH remains incompletely understood. In this study, we found that BACH1 expression rose rapidly and peaked at 24\u202fh after SAH. Both neurons and microglia exhibited detectable BACH1 expression. Silencing BACH1 with siRNA markedly alleviated neuroinflammation and oxidative stress, and improved neurological performance. Additionally, BACH1 suppression shifted microglial phenotypes by diminishing the M1 response and enhancing M2 polarization. Further analysis revealed that inhibiting BACH1 activated the Nrf2-dependent pathway, whereas Nrf2 depletion with ML385 diminished the protective effects associated with BACH1 knockdown. Collectively, these results identify BACH1 as a promising candidate for alleviating brain damage associated with SAH.",
"42346280": "ID: 42346280\nTitle: Gastric Juice miR-106a-5p as a Non-Invasive Biomarker of Neuroinflammation and Neurodegeneration: A Prospective Observational Study.\nAbstract: Neuroinflammation is a key contributor to the progression of several neurodegenerative disorders, including Alzheimer's disease, stroke, and small vessel disease. Emerging evidence highlights the role of circulating microRNAs (miRNAs) as non-invasive biomarkers of neuroinflammation and neuronal injury. miR-106a-5p, a member of the miR-17~92 cluster, is known to regulate inflammation, apoptosis, and vascular function. While typically studied in plasma or cerebrospinal fluid, gastric juice miRNAs represent a novel and underexplored source for biomarker discovery within the gut-brain axis. This exploratory study aimed to investigate the association between gastric juice miR-106a-5p expression and markers of neuroinflammation, including C-reactive protein (CRP), lactate dehydrogenase (LDH), and imaging-based evidence of neurodegeneration. A prospective, observational study was conducted on 38 participants (22 with neurodegenerative pathology and 16 healthy controls). Gastric juice samples were analyzed for miR-106a-5p using RT-qPCR, normalized to U6 snRNA. \u0394Ct values were used to determine relative expression. Statistical analyses included t-tests/Wilcoxon tests, ROC curve analysis, and correlation testing, with significance set at p < 0.05. Patients with neurodegenerative changes exhibited significantly lower gastric miR-106a-5p expression compared to controls (p = 0.044). Elevated CRP and LDH levels were associated with higher \u0394Ct values (indicating lower expression), with p-values of 0.019 and 0.023, respectively. ROC analysis showed moderate diagnostic accuracy (AUC = 0.701) for miR-106a in identifying neurodegenerative status. miR-106a levels also correlated inversely with carotid intima-media thickness and brain MRI abnormalities, also reduced gastric miR-106a-5p expression is associated with systemic inflammation and neuroimaging evidence of neurodegeneration. While causality cannot be inferred, these findings suggest that gastric miR-106a may serve as a promising non-invasive biomarker within the gut-brain axis framework. Further longitudinal and mechanistic studies are warranted to validate its clinical utility and explore its potential role in monitoring neuroinflammatory conditions.",
"42346775": "ID: 42346775\nTitle: GV-971 Ameliorates Chronic Restraint Stress-Induced Depression-like Phenotypes Accompanied by Reshaping of the Microbiota-Gut-Brain Axis.\nAbstract: Depression is increasingly linked to microbiota-gut-brain axis dysfunction, yet current monoaminergic antidepressants show limited efficacy. This study investigated the therapeutic potential and underlying mechanisms of GV-971, a marine-derived oligosaccharide, in a chronic restraint stress (CRS) mouse model. We first established that 8 h of daily restraint for 4-8 weeks induces a stable depression-like phenotype characterized by behavioral despair and significant reduction in peripheral monoamine neurotransmitters (5-HT and norepinephrine). GV-971 treatment robustly attenuated CRS-induced depression- and anxiety-like behaviors, restored hippocampal serotonin levels, reduced elevated plasma corticosterone concentrations, and ameliorated CRS-induced adrenal cortical hyperplasia. Mechanistically, GV-971 significantly suppressed neuroinflammation by inhibiting microglial hyperactivation in the prefrontal cortex and hippocampus. Concurrently, it repaired intestinal barrier dysfunction, evidenced by reduced permeability, restored mucosal integrity, and recovered goblet cell numbers. Crucially, integrated shot-gun metagenomics and plasma metabolomics revealed that GV-971 not only reshaped microbial taxonomy but also functionally recalibrated the gut ecosystem. It enriched beneficial taxa (e.g., Bifidobacterium pseudolongum, Bacteroides uniformis) and specific metabolic pathways, leading to increased short-chain fatty acids (valeric and caproic acids) and a significant reduction in plasma levels of tryptophan-kynurenine pathway metabolites, specifically the neurotoxic compounds kynurenine and quinolinic acid. Fecal microbiota transplantation (FMT) from GV-971-treated donors partially recapitulated the antidepressant and gut-protective effects in CRS recipients, confirming a causal role for the remodeled microbiota. Collectively, GV-971 exerts antidepressant effects by coordinately remodeling the gut microbiota, normalizing tryptophan and SCFA metabolism, restoring gut barrier integrity, and dampening central neuroinflammation, supporting its potential as a novel gut-brain axis-targeted therapy for depression.",
"42356295": "ID: 42356295\nTitle: From Leaky Gut to a Vulnerable Brain: Obesity-Associated Gut Barrier Failure in Colorectal Cancer and Cognitive Dysfunction.\nAbstract: Obesity is a major risk factor for colorectal cancer (CRC) and is increasingly recognized as a contributor to cancer-related cognitive impairment; however, the mechanistic pathways linking metabolic dysfunction, tumor progression, and brain dysfunction remain incompletely defined. Emerging evidence indicates that obesity-induced gut microbial dysbiosis and intestinal barrier disruption may serve as a biologically plausible mechanism connecting these processes via the gut-brain axis although direct clinical causality remains to be firmly established. In obesity, alterations in gut microbiota composition characterized by depletion of barrier-protective taxa and enrichment of pro-inflammatory and genotoxic pathobionts compromise epithelial tight-junction integrity and promote metabolic endotoxemia. The translocation of microbial products, including lipopolysaccharide, sustains chronic systemic inflammation, accelerates CRC progression, and remodels the tumor microenvironment. Notably, these peripheral inflammatory signals extend beyond the intestine and tumor, disrupting blood-brain barrier integrity, activating microglia and astrocytes, and impairing synaptic plasticity within hippocampal and frontal networks. Clinically, these processes manifest as cancer-related cognitive impairment (CRCI), with predominant deficits in attention, processing speed, and working memory, which are often detectable around the time of diagnosis and independent of chemotherapy exposure. This review synthesizes in vivo, in vitro, and human evidence into a proposed theoretical \"two-barrier failure\" model of obesity-associated CRC and cognitive dysfunction. In addition to mechanistic synthesis, we discuss barrier-centered therapeutic strategies, including targeted probiotics, postbiotics, SCFA supplementation, obesity management through dietary and weight-loss interventions, and potential pharmacological approaches to epithelial and neurovascular barrier protection. We also outline testable clinical trial designs for evaluating these interventions in obesity-associated CRC.",

Structurally, PELNs feature a phospholipid bilayer homologous to plant cell membranes, encapsulating bioactive components such as proteins, nucleic acids, lipids, and secondary metabolites. The native structure of PELNs endows them with enhanced bioavailability, reduced immunogenicity, and improved barrier penetration for precise tissue delivery. Recent studies highlight the cross-kingdom therapeutic potential of PELNs in mammals, including antitumor, anti-inflammatory, tissue repair, immunomodulation and so on.

In this cross-sectional investigation, we enrolled 205 older Chinese adults: 52 healthy controls, 83 hypertensive individuals with normal cognition (HTN-CN), and 70 hypertensive subjects with aMCI (HTN-aMCI). Gut microbiota composition was profiled by 16S rRNA sequencing, and serum levels of 27 inflammatory mediators were quantified by multiplex immunoassay. Compared to the HTN-CN and control groups, the HTN-aMCI group showed not only a greater richness of gut microbes but also a markedly segregated microbial community structure. The HTN-aMCI microbiota was characterized by significant depletion of short-chain fatty acid (SCFA)-producing genera (Roseburia, Blautia, Faecalibacterium) and enrichment of opportunistic pathogens (Streptococcus, Clostridium_sensu_stricto_1, Enterococcus). Co-occurrence network analysis revealed disrupted microbial interactions in HTN-aMCI, and functional prediction showed enhanced lipopolysaccharide biosynthesis and reduced SCFA metabolism. HTN-aMCI patients had elevated pro-inflammatory cytokines (IL-1\u03b2, IL-6, IL-8, IL-17, IP-10, RANTES). Notably, after FDR correction, Blautia abundance correlated negatively with inflammatory markers and positively with cognitive scores, whereas pathobionts showed opposite patterns (all q < 0.05). These findings indicate that hypertensive individuals with aMCI harbor a specific gut microbial dysbiosis marked by loss of SCFA producers, expansion of pathobionts, and disrupted microbial networks, which together associate with systemic inflammation and cognitive decline. Our results support the notion that targeting gut microbiota might represent a potential therapeutic avenue for hypertension-related cognitive impairment.",

Literature search was conducted using PubMed, Cochrane, Embase, and CENTRAL from January 2000 to March 2026. Search terms included \"Sarcopenia\", \"Mild Cognitive Impairment\", and \"Dementia\". Eighty-two studies met inclusion criteria (54 clinical; 28 interventions), discussing epidemiological trends, mechanistic pathways, biomarkers, and therapeutic targets. Clinical evidence clustered across inflammation, vascular change and energetics, hormonal-metabolic dysregulation, and biomarkers. Elevated inflammatory mediators tracked slower gait, weaker grip, and poorer cognition, mapping to mobility decline and Montreal Cognitive Assessment (MoCA) deficits. Cross-domain readouts linked muscle and brain: muscular fat infiltration related to worse cognitive-motor performance; temporalis muscle thickness correlated with MoCA and tau signal; impaired post-exercise phosphocreatine recovery associated with higher neurodegeneration risk and slower processing/gait. Blood biomarkers consistently stratified motor-cognitive status/decline. Among intervention reports, aerobic/resistance training improved strength, mobility, and often processing outcomes; protein (\u00b1 vitamin D) and n-3 polyunsaturated fatty acid showed supportive but heterogeneous effects; vitamin D alone showed mixed muscle results but associated with lower dementia incidence; single-pathway metabolic/anti-cytokine strategies were mixed. Few studies powered dual musculoskeletal-cognitive endpoints, limiting quantitative synthesis. There is compelling evidence for bidirectional crosstalk between sarcopenia and cognitive impairment. However, evidence substantiating shared interventions remains limited and could benefit from more multi-center dual-outcome randomized controlled trials. Establishing consensus risk stratification criteria based on common biomarkers may support integrated management of these conditions, improving patient outcomes.",

Microbial metabolites such as short-chain-fatty-acids, bile acids, and amino acid derivatives serve as pivotal modulators of mitochondrial bioenergetics, oxidative stress management, and fission-fusion processes. These interactions are vital for preserving epithelial integrity, supporting energy metabolism, shaping immune responses, and managing inflammatory signaling pathways. Disruptions within this microbiota-mitochondria axis are associated with various pathologies, including non-alcoholic fatty liver disease, obesity, type 2 diabetes, and chronic inflammatory conditions like inflammatory bowel disease. Additionally, growing evidence connects gut dysbiosis and mitochondrial dysfunction to neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease, highlighting the importance of this bidirectional relationship in maintaining neuronal health. On a mechanistic level, pathways involving AMPK, sirtuins, and PGC-1\u03b1 govern mitochondrial biogenesis and adaptive responses to microbial signals. Dysregulation of these pathways can heighten oxidative stress, hinder mitophagy, and contribute to systemic inflammation. Emerging therapeutic strategies aim to target this axis through dietary modifications, probiotics and engineered microbes, FMT, and mitochondria-specific pharmacological treatments. These interventions focus on restoring metabolic stability, enhance resilience against oxidative damage, and slowing disease progression. By integrating insights from fields such as metabolism, immunology, and neuroscience, this review positions the microbiota-mitochondria axis as a critical area of focus in biomedical research. A deeper understanding of this communication network offers promising opportunities for precision therapies aimed at addressing metabolic, inflammatory, and neurodegenerative diseases.",

DNA methylation-based epigenetic clocks, particularly measures of the pace of aging such as DunedinPACE, are sensitive to relatively short-term changes in aging processes. However, evidence from randomized controlled trials remains limited. We conducted a randomized controlled trial to test a 12-week multimodal lifestyle intervention comprising exercise and dietary guidance involving daily consumption of yogurt containing Bifidobacterium longum BB536 on DNA methylation-based aging measures in overweight men aged \u226550 years. The intervention group exhibited a significant deceleration in DunedinPACE, corresponding to an estimated 2.2% slower pace of aging, whereas no meaningful change was observed in the control group. Exploratory analyses further identified a significant reduction in DNAmCystatinC, a renal-related GrimAge surrogate marker, while no clock within the biological age remained significant after false discovery rate correction. These findings suggest that a feasible, multimodal lifestyle intervention-including exercise and dietary guidance with daily consumption of yogurt containing Bifidobacterium longum BB536-may be associated with short-term changes in selected DNA methylation-based aging measures. Larger and longer-term studies are warranted to confirm the durability and clinical relevance.

"42377735": "ID: 42377735\nTitle: The interplay between gut microbiota and Alzheimer's disease: mechanistic insights from dysbiosis to disease modulation.\nAbstract: Alzheimer's disease (AD) is a chronic, progressive, neurodegenerative condition marked by memory loss and cognitive decline. It is characterized by neuropathological features such as amyloid plaque accumulation, neurofibrillary tangles of tau protein, and inflammatory changes in the brain. Recent research emphasizes how gut microbes influence the onset and progression of AD primarily through the gut-brain connection, a bidirectional communication system. The human gastrointestinal tract (GI) contains trillions of bacteria, primarily Bacteroidetes, Firmicutes, and Actinobacteria, which play vital roles in digestion, metabolic regulation, and immune modulation. However, factors such as diet, lifestyle, and environmental exposure can disrupt microbial balance, weaken intestinal barrier function, and initiate systemic inflammation. Such dysbiosis has been linked to defective regulation of the amyloid precursor protein (APP), leading to increased deposition of amyloidogenic peptides (A\u03b2). Moreover, the enteric nervous system, which expresses APP, may serve as an initial site of amyloid deposition, affecting gastrointestinal motility and inflammatory susceptibility. The gut microbiota also produces key bioactive compounds, including neurotransmitters such as serotonin, dopamine, acetylcholine, histamine, and gamma-aminobutyric acid (GABA), which influence the central nervous system (CNS) through neural, immune, and endocrine pathways. An imbalance in these neuroactive molecules may disrupt synaptic signaling and contribute to Alzheimer's-related cognitive dysfunction. Therefore, improving our understanding of gut-brain communication may advance knowledge of AD development and support the creation of new therapies. This review highlights the strong association between intestinal microbes and Alzheimer's pathogenesis, emphasizing microbiota modulation through probiotics, prebiotics, postbiotics, synbiotics, and antibiotics as potential therapeutic approaches, supported by emerging clinical trial evidence.",

Here, we investigated the pharmacological effects of the N-palmitoylethanolamine oxazoline derivative 2-pentadecyl-2-oxazoline (C15OXA) in a mouse model of high-fat diet (HFD)-induced obesity, with particular attention to its central and peripheral mechanisms of action. Male C57Bl/6J mice were fed an HFD for 12 weeks and subsequently treated with C15OXA (30\u00a0mg\u00b7kg-1, p. o.) for 7 weeks. Behavioural, molecular, and microbiota analyses were performed to evaluate the effects of the compound. C15OXA significantly reduced anxiety-like behaviour in obese mice without affecting body weight, fat mass, or glucose tolerance. At the central level, C15OXA attenuated hippocampal neuroinflammation, as shown by reduced expression of COX-2, TLR4, NLRP3 and IL-1\u03b2. In parallel, C15OXA restored tight junction gene expression associated with blood-brain barrier integrity, and modulated unfolded protein response signalling. In addition, C15OXA enhanced markers of neurogenesis and synaptic plasticity. At the peripheral level, C15OXA treatment reduced colonic inflammation and improved gut barrier integrity. These effects were associated with a targeted reshaping of gut microbiota composition. In particular, C15OXA promoted the enrichment of butyrate- and menaquinone-producing bacteria, as taxa linked to beneficial metabolic functions. Overall, these findings suggest that C15OXA exerts anxiolytic-like effects associated with coordinated central and peripheral pathways involving the modulation of neuroinflammatory pathways, barrier integrity, and gut-brain axis signalling. This study provides novel pharmacological insight into the therapeutic potential of C15OXA for the treatment of obesity-associated neuropsychiatric disorders.",

Inhibiting 15-PGDH by pharmacologic blockade or partial genetic reduction restores redox homeostasis and mitigates microglial and astrocyte activation, dopaminergic neuron loss, and motor impairment across three mouse models of PD. These models included systemic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), intranigral lipopolysaccharide (LPS), and intrastriatal AAV-\u03b1-synuclein with intra-ventral tegmental area \u03b1-synuclein preformed fibrils (PFFs). The neuroprotective efficacy of 15-PGDH inhibition in PD is shown to be mediated by downregulation of the dopaminergic neuronal cell death mediator lipocalin-2 (Lcn2), the pro-inflammatory cytokine interleukin-1\u03b2, the reactive oxygen generator Cybb/Nox2, and oxidative tissue damage. Mechanistically, in vitro exposure of BV2 microglia to LPS recapitulates induction of Lcn2, Cybb/N OX2 and superoxide, and all three of these effects are reversed by co-treating with prostaglandin E2 (PGE2), the prototypical degradation substrate of 15-PGDH. With a 15-PGDH inhibitor (MF-300) currently in human clinical trials for peripheral indications, these findings have translational relevance for PD.",

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.",

Despite contemporary treatments, many patients still experience disease progression, with some ultimately losing vision. The purpose of this review is to demonstrate how derangements in mitochondrial biology underpin the pathophysiology of glaucoma, and to explore emerging therapeutic options. Literature searches were performed using multiple databases, aiming to identify recent developments in the scientific knowledge surrounding mitochondrial biology and glaucoma. Key words used in the primary literature search included combinations of \"glaucoma\", \"mitochondria\", \"oxidative stress\", \"metabolism\", \"inflammation\", \"transport\" and \"genetics\". Additional database searches were performed to further explore specific details identified in the primary search. Recent research points to mitochondrial insufficiencies as a primary culprit in the pathophysiology of glaucoma. Dysfunction of mitochondria occurs in a multitude of ways, and is an integral component of neuroinflammation, metabolic compromise, and disruption of axonal transport. This in part results from accumulated genetic factors, leading to generation of superoxides that damage retinal ganglion cells resulting in neurodegeneration of the optic nerve. Defects in mitochondrial biology among a range of ocular cell types contribute to the progression of glaucoma. With this understanding, emerging treatments targeting mitochondria, including gene therapies, tunneling nanotubules, and pharmacotherapeutics which enhance mitochondrial function and reduce oxidative stress, are likely the future of glaucoma management. By targeting mitochondrial insufficiencies as a root cause of glaucoma in addition to managing intraocular pressure, this new approach offers hope for preventing vision loss and potentially curing glaucoma.",

Studies have reported contradictory results regarding the efficiency of milk fermentation in microbial inactivation. Therefore, this meta-analysis aimed to evaluate the effect of fermentation on the inactivation of E. coli and S. aureus during yogurt processing and storage. The analysis was performed on 46 studies and 81 effect sizes, selected in accordance with PRISMA guidelines. Data were analyzed using Random and Mixed-Effects Models fitted with the REML estimator in the R environment using metafor. Results showed that yogurt storage exhibited the highest E. coli and S. aureus inactivation (4.66 log CFU/mL) compared to yogurt processing (1.68 log CFU/mL). Over 50% of the studies exhibited high pathogen reduction, with an interquartile range of 91.12 to 99.93% (median\u00a0=\u00a098.74%) and 99.89 to 100% (median\u00a0=\u00a0100%) during fermentation and storage, respectively. E. coli and S. aureus had higher reductions of 4.41 and 4.96 log CFU/mL during storage, respectively. Meta-regression showed that mesophilic and thermophilic temperatures and milk fermentation in the 0-12\u00a0h category had significantly higher S. aureus reduction (p\u00a0<\u00a00.05). Storage of milk for 37-48\u00a0h showed a greater E. coli reduction. Large inoculum size of over 6 log CFU/mL and the region Europe significantly influenced pathogen reduction. The results showed that a combination of milk fermentation and storage can eliminate E. coli and S. aureus, contributing to the safety of yogurt.",

The vast majority of patients are diagnosed at the symptomatic stage, when substantial neuronal loss has already occurred and the therapeutic window for disease-modifying treatment has closed. Recently approved disease-modifying therapies have created an urgent clinical need for pre-symptomatic patient identification. The cardiovascular risk factors most commonly managed in primary care -- hypertension, dyslipidemia, type 2 diabetes, atrial fibrillation, and chronic heart failure -- are among the most powerful modifiable antecedents of AD pathology, operating through systemic inflammation, cerebral small vessel disease, impaired glymphatic clearance, and tau hyperphosphorylation. The biomarkers used to monitor these conditions -- C-reactive protein, cardiac troponin, NT-proBNP, and homocysteine -- reflect active neurodegeneration risk processes already measured routinely in primary care. This clinical perspective proposes a three-stage\u00a0integrated neuro-cardiological screening protocol linking cardiovascular biomarker assessment to plasma P-tau217 blood testing for AD confirmation. This framework addresses the implementation gap identified in recent United States primary care literature and represents a practical step toward closing the AD diagnostic gap.",

Sinomenine (Sino), a bioactive alkaloid derived from Sinomenium acutum, exhibits anti-inflammatory and anti-apoptotic activities; however, its molecular targets and mechanisms in AIS remain unclear. This study aimed to identify potential targets and key pathways of Sino and validate its neuroprotective effects in AIS. A combined approach integrating network pharmacology, Mendelian randomization (MR), molecular docking, and in vivo validation was adopted. Potential targets of Sino and ischemic stroke were identified using public databases. Overlapping targets were analyzed through protein-protein interaction network construction and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Sprague-Dawley rats were randomly assigned to four groups, and a middle cerebral artery occlusion/reperfusion (MCAO/R) model was established (n = 12 per group): Sham, MCAO/R, Sino (20 mg/kg), and Sino +LY294002 (LY, 10 mg/kg). Sino and Sino + LY were administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Sham and MCAO groups were given the same amount of physiological saline undergoing the same procedures. Sino was administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Neurological deficits, infarct volume, neuronal injury, apoptosis, activation of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway, and inflammatory responses were assessed using behavioral tests, 2,3,5-Triphenyltetrazolium chloride (TTC)/Nissl/Terminal deoxynucleotidyl transferase dUTP Nick End Labeling (TUNEL) staining, Western blotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA). Twelve overlapping targets between Sino and ischemic stroke were identified, with Akt1 recognized as a central hub. Enrichment analysis highlighted the PI3K/Akt pathway as a critical signaling axis, while MR analysis indicated a nominal association between Akt1 and ischemic stroke. Molecular docking predicted stable binding between Sino and Akt1. In MCAO/R rats, Sino significantly improved neurological function, reduced infarct volumes, attenuated neuronal apoptosis, and increased neuronal survival. Mechanistically, Sino increased the p-PI3K/PI3K and p-Akt/Akt ratios, upregulated Bcl-2 expression, and decreased the expression of Bax, cleaved caspase-3, ionized calcium-binding adapter molecule 1 (Iba1), inducible nitric oxide synthase (iNOS), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1). These beneficial effects were notably attenuated by LY. This study establishes PI3K/Akt as a functionally necessary mediator of Sino's neuroprotection against cerebral ischemia/reperfusion injury. The incomplete LY reversal indicates multi-target activity, supporting Sino's development as an adjunctive therapeutic candidate for ischemic stroke.",
"42416017": "ID: 42416017\nTitle: Mechanisms of multi-organ damage in Wilson disease from the gut-liver-brain axis perspective: copper metabolism, gut microbiota, and metabolite communication.\nAbstract: Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations, leading to pathological copper deposition in the liver, brain, and cornea. Although the gut-liver-brain axis plays a role, direct copper accumulation in multiple organs remains the primary cause of tissue damage. Recent years have seen growing attention to the gut microbiota in WD pathogenesis. Copper imbalance remodels gut microbiota composition and function, while dysbiosis, in turn, affects copper absorption and excretion, forming a vicious cycle that exacerbates multi-organ damage. Copper-induced intestinal barrier disruption, lipopolysaccharide translocation, and systemic inflammation are key links connecting local copper accumulation to systemic injury. This review summarizes the genetic basis of WD, mechanisms of copper toxicity, gut microbiota alterations, and their roles in liver injury and neurodegeneration. It highlights microbiota-derived metabolites-short-chain fatty acids, tryptophan metabolites, bile acids, sulfur-containing amino acids, and branched-chain amino acids-in inter-organ communication. The bidirectional interaction between WD therapies (chelators, zinc salts, dietary interventions) and the gut microbiota is analyzed, along with microbiota-based personalized therapies. However, most current evidence derives from animal models or small cross-sectional studies; large-scale longitudinal human data are critically lacking. A deeper understanding of the gut-liver-brain axis in WD may reveal novel biomarkers and therapeutic targets.",
"42416049": "ID: 42416049\nTitle: GLP-1 receptor agonists in neurological diseases: mechanisms and therapeutic prospects from metabolism to neuroprotection.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are widely used metabolic therapies for type 2 diabetes and obesity, with well-established cardiovascular benefits. Beyond glycemic control, accumulating experimental and clinical evidence suggests that GLP-1RAs exert pleiotropic actions relevant to neurological diseases. Metabolic dysfunction, chronic inflammation, oxidative stress, mitochondrial impairment, and neurovascular injury represent convergent mechanisms that contribute to neurodegeneration, cerebrovascular pathology, and metabolism-related brain disorders. Notably, these processes overlap with pathways modulated by GLP-1 signaling across systemic and central compartments. GLP-1 receptors are expressed in neurons, glial cells, and components of the neurovascular unit, providing a biological basis for possible neurological effects. Preclinical studies suggest that GLP-1RAs can reduce neuroinflammation and oxidative stress, support mitochondrial function, and help maintain blood-brain barrier integrity. Clinical findings, however, remain inconsistent. Studies in Parkinson's disease have reported encouraging signals, but biomarker evidence for disease modification is still limited. In Alzheimer's disease, clinical trials have produced mixed or negative results. These differences may reflect disease stage, patient selection, drug-specific pharmacology, central nervous system exposure, endpoint sensitivity, and treatment duration. Overall, GLP-1RAs may influence neurological disease through metabolic, inflammatory, and vascular pathways, but their clinical role remains unsettled. Future studies should use biomarker-informed designs, prespecified neurological endpoints, appropriate drug selection, and sufficiently long follow-up to determine which patients and disease stages are most likely to benefit.",

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.",

This chapter comprehensively examines the scientific principles, sustainability implications, and future trends of these alternatives. Scientifically, the primary challenge lies in forming firm gel structures and desirable flavor compounds by fermenting non-dairy substrates which lack the inherent composition and structure of bovine milk. The possible strategies to address the two hurdles faced by the non-dairy yogurt industry are discussed, including a comparison of their respective merits and limits. The sustainability assessment is conducted from four aspects-nutrition, economy, society, and environment, alongside an analysis of health implications. The future trends of non-dairy yogurt alternatives, including the utilization of novel protein substrates (e.g., microbial protein and microalgae), assistance of artificial intelligence and novel biotechnology, and the development of personalized products with targeted nutritional profiles are discussed. With significant scientific breakthroughs emerging, non-dairy yogurts, in our opinion, are positioned to do more than compete with dairy. They are set to redefine consumers' expectations of yogurt entirely.",

Although irritable bowel syndrome (IBS) is considered a disorder of gut-brain interaction, the role of UA in IBS remains unclear. An experimental rat model of IBS was induced using laser-induced shock waves (LISW) applied to the head. Hyperuricemia (HUA) was induced by intraperitoneal administration of inosine monophosphate and potassium oxonate. Visceral hypersensitivity was assessed by colorectal distension. Ileal mucosal permeability was measured using the Evans blue method. CRFR1 mRNA expression in the rectum, IL-10 and TGF-\u03b21 expression in the ileum, and IL-1\u03b1, IL-1\u03b2, and TNF expression in the medial prefrontal cortex (mPFC) and paraventricular nucleus (PVN) were quantified by qRT-PCR. Vagal involvement was assessed using subdiaphragmatic vagotomy or atropine treatment. LISW increased visceral hypersensitivity, ileal mucosal permeability, and rectal CRFR1 expression and reduced IL-10 expression in the ileum. HUA significantly ameliorated these changes. HUA was also associated with reduced IL-1\u03b2 expression in the mPFC and reduced IL-1\u03b1 and IL-1\u03b2 expression in the PVN in LISW-treated animals. Importantly, the ameliorative effects of HUA on visceral hypersensitivity were abolished by vagotomy or atropine treatment. Hyperuricemia ameliorated LISW-induced visceral hypersensitivity, improved ileal mucosal permeability, restored IL-10 expression in the ileal mucosa, and reduced proinflammatory cytokine expression in the brain. The loss of HUA-induced suppression of visceral hypersensitivity after vagotomy or atropine treatment suggests the possible involvement of vagal and cholinergic brain-gut communication. Irritable bowel syndrome (IBS) is a common disorder in which people experience abdominal pain and bowel problems, often worsened by stress. We examined whether uric acid, a major endogenous antioxidant in the human body, can protect against changes seen in a rat model of IBS. An experimental model of IBS was created by applying laser\u2010induced shock waves to the head, leading to increased sensitivity to colorectal distension (a measure of visceral hypersensitivity), impaired barrier function of the lower small intestine, and reduced a protective anti\u2010inflammatory signal (IL\u201010) in the gut. Increasing blood uric acid levels reduced visceral hypersensitivity, improved the barrier function of the lower small intestine, and restored IL\u201010 levels. Importantly, the uric acid\u2013induced suppression of visceral hypersensitivity was lost when vagus nerve signaling was disrupted, indicating that vagal and cholinergic signaling is involved in this effect.",

Emerging evidence indicates that various oral disease-associated protein molecules are implicated in the pathogenesis of diverse neuronal disorders, including neurodegenerative diseases. This review comprehensively summarizes oral disease-related protein molecules involved in several neuronal disorders, including Alzheimer's disease, Parkinson's disease, neurodegeneration, neuroinflammation, dementia, cognitive decline, and brain fog in two different contexts. Firstly, it describes protein molecules under the classical oral disease condition [A\u03b242, total-Tau, phosphorylated-Tau, \u03b1-synuclein, DJ-1, lactoferrin, MMP-2/8/9, IL-6, IL-1\u03b2, TNF-\u03b1, CRP, S100A8, S100A9, S100B, RAGE, LCN2, cathepsin B/L, HSP70/90, NfL, CXCL2/8, C3/4, defensins (\u03b1 and \u03b2), and lysozyme]. Secondly, it explains in COVID-19 context [ACE2, TMPRSS2, furin-1, NRP1, spike, T1R, and T2R]. The review explores oral proteins implicated in neuronal disorders, highlighting their roles in activating inflammatory pathways, contributing to memory impairment, and mediating taste dysfunction in the context of COVID-19. Furthermore, the review delineates the mechanisms underlying the oral-brain axis, highlighting the roles of systemic inflammation, microbial interactions, and blood-brain barrier dysfunction in mediating these effects. It also highlights the innovative diagnostic potential of oral disease-associated proteins as non-invasive biomarkers for early detection and monitoring of neuronal disorders in both classical and COVID-19 contexts. In addition, the emerging therapeutic significance of these proteins is discussed, emphasizing their potential as molecular targets for the prevention and treatment of neurological diseases.

We enrolled 48 stable COPD patients, categorized into cognitively normal (CogN, n = 22) and impaired (Cog, n = 26) groups based on Montreal Cognitive Assessment (MoCA) scores, along with 34 matched healthy controls. All participants underwent 3T MRI with quantitative susceptibility mapping (QSM) to quantify regional brain iron content. Group comparisons of whole-brain and region-of-interest susceptibility were performed. Mediation analysis was then used to test whether specific brain iron deposition mediates the relationship of both COPD status and peripheral inflammatory markers with cognitive performance. Cog patients showed increased total iron in the right cerebellum crus I, while CogN patients exhibited higher paramagnetic susceptibility (\u03c7para) in the left orbitofrontal cortex (OFC), right precentral gyrus, and right brainstem. \u03c7para in the left OFC and right brainstem were positively correlated with total MoCA, abstraction, and orientation scores. Mediation analysis demonstrated that \u03c7para of the left OFC mediated the effects of both COPD status and systemic neutrophil counts on impaired abstraction. Additionally, right brainstem \u03c7para mediated the relationship between COPD and deficits in orientation. COPD patients with cognitive impairment exhibited distinct patterns of brain iron deposition. Importantly, deposition in several key regions served as a potential mediator, linking both COPD and systemic inflammation to specific cognitive deficits. These preliminary findings suggest a possible association between brain iron accumulation and cognitive impairment in COPD, offering candidate neuroimaging markers for early identification.\u2009\u2009.",

We performed RNA-sequencing on brain, optic nerve head (ONH), and retina from four genetically diverse mouse strains (B6, CAST, NZO, WSB) following lipopolysaccharide (LPS)-induced systemic inflammation. The ONH mounted the largest response to LPS (9510 DEGs), followed by retina (5152) and brain (4586). A conserved core of 1444 DEGs across all tissues was enriched for innate immune and acute-phase pathways. Tissue-specific responses were apparent; the retina downregulated phototransduction and visual perception genes; ONH exhibited bidirectional remodeling with upregulated proteasome and ribosome biogenesis and suppressed lipid metabolism and lysosomal function; yet the brain displayed no significant pathway level enrichment. Genetic background strongly modulated the LPS response across the three tissues; the retina exhibited the greatest strain-dependent divergence. Interestingly, differing genetic context affected the ONH response to LPS the least despite its markedly larger response to LPS overall. In totality, both genetic and physical context dictate the neuroinflammatory response to LPS.",

Although traditionally studied in isolation, accumulating evidence indicates that these conditions are mechanistically interconnected through shared pathways, including chronic systemic inflammation, endothelial dysfunction, and dysregulated lipid metabolism. Here, we propose a cardio-neuro axis in which vascular and neurodegenerative processes are linked along a continuum that is modifiable through diet. In this perspective, we synthesise evidence linking inflammatory and neurovascular dysfunction across CVD and ND and argue that nutrition represents a primary, yet under-integrated, lever for targeting these shared mechanisms. We focus on dietary patterns and bioactive components that influence inflammation resolution, endothelial function, and metabolic homeostasis. However, despite strong mechanistic rationale, nutritional strategies for ND remain fragmented, with an overreliance on single-nutrient interventions and limited incorporation of vascular endpoints or mechanistic biomarkers. We contend that progress in this field requires a shift from reductionist approaches toward whole-diet interventions evaluated using integrated cardio-neuro outcomes, alongside stratified and personalised designs. Embedding nutrition within a unified cardio-neuro framework earlier in life may offer a scalable and mechanistically grounded strategy to reduce the burden of NCD across the life course.",

Given the literature documenting chronic persistent inflammation in older Black adults, we investigated the association between circulating inflammatory proteins and cognitive decline in this high-risk population. We used data (n\u2009=\u2009642) from the Minority Aging Research Study (MARS) and the Rush Clinical Core, including plasma samples to assess circulating inflammatory proteins (Olink\u00ae Target-96 Inflammation) and cognition (global cognition and five cognitive domains) assessed annually following proteomics measurement using previously stored blood samples. Linear mixed-effect and latent class mixed models (age at blood draw for proteomics measurement, sex, and education-adjusted), and elastic-net regression were used. Statistical significance was determined using an FDR threshold of 10%. Participants (62.3 to 99.4 years) were mostly women (80.68%) with 15.1 years of education. In multivariable linear mixed-effect models, we found that higher levels of osteoprotegerin (OPG) and chemokine (C-C motif) ligand 23 (CCL23) were cross-sectionally associated with poorer global cognition (beta=-0.205 and beta=-0.148), and higher CCL23 was associated with poorer semantic memory (beta=-0.206). Furthermore, protein\u2009\u00d7\u2009time interaction analyses indicated that higher OPG, Stem cell factor (SCF), and chemokine (C-X-C motif) ligand 9 (CXCL9) levels were associated with faster decline in global cognition (OPG\u2009\u00d7\u2009time term: beta=-0.042), semantic memory (SCF\u2009\u00d7\u2009time term: beta=-0.059, OPG\u2009\u00d7\u2009time term: beta=-0.043), episodic memory (SCF\u2009\u00d7\u2009time term: beta=-0.064; OPG\u2009\u00d7\u2009time term: beta=-0.044), and visuospatial ability (CXCL9\u00d7time term: beta=-0.012). In latent class mixed models, several significant protein\u2009\u00d7\u2009time interactions were observed for episodic memory in the subgroup with initial below-average performance and gradual decline.

However, the underlying causes of psychiatric disorders in patients with IBD remain unclear, and effective treatment strategies have yet to be established. Herein, we developed oral gastroprotective \u03b2G@Apr-WPG NMs (\u03b2-glucan armored apremilast encapsulating tryptophan-poly(lactic-co-glycolic acid)-glutathione nanomicelles).

Emerging evidence implicates metabolic impairment, mitochondrial dysfunction, oxidative stress, and neuroinflammation as central contributors to HD pathogenesis, thereby highlighting novel avenues for therapeutic intervention beyond conventional strategies. In this context, drug repurposing has gained considerable attention as an efficient approach to accelerate therapeutic development. Alogliptin has multiple complementary mechanisms of action that exert neuroprotective effects through inhibition of DPP-4 to boost endogenous incretin signaling (especially GLP-1), inhibition of inflammatory pathways, inhibition of oxidative stress, preservation of mitochondrial function, and modulation of neuronal survival signaling. The review summarizes existing data on the contribution of the incretin signaling to neuroprotection and critically analyzes the mechanism through which alogliptin might regulate important pathological events in HD, such as apoptosis, oxidative stress, and neuroinflammation. Additionally, preclinical results and pharmacological properties in favor of its translational potential are presented, as well as the reflection on its clinical usage and additional research perspectives. Even though direct evidence in HD is not extensive, the overlap of metabolic and neurodegenerative pathways offers a strong argument to study.

Advances in single-cell and single-nucleus transcriptomics, chromatin accessibility profiling, and spatial multi-omics have negated binary frameworks of 'resting versus activated' or 'M1 (pro-inflammatory) versus M2 (anti-inflammatory)' and revealed a multidimensional state space that supports brain development, homeostasis and adaptive responses to perturbation. Building on the foundational concepts of the microglial sensome, homeostatic and disease-associated signatures, microglia exhibit transcriptomic state transitions in neurodegeneration, demyelination, infection and systemic inflammation. Moreover, a mechanistic framework for more 'hidden' microglial states\u00a0has emerged, in which latent programmes that appear homeostatic at baseline are revealed by challenges and are instructed through innate immune training or tolerance. We argue that these covert reprogrammed states, which are shaped by ageing, genotype, sex, location and prior exposures such as sepsis or viral infection, help explain interindividual variability in disease trajectories. We conclude by outlining priorities for unifying state annotation across species and modalities, and for translating state-resolved insights into biomarkers and interventions.",

Peripheral blood serves as a minimally invasive source of transcriptomic biomarkers reflecting systemic inflammation, mitochondrial dysfunction, lysosomal impairment, and disrupted RNA processing-key pathways involved in PD. Long-read RNA sequencing with Oxford Nanopore Technologies (ONT) offers unprecedented detail of full-length transcripts, alternative isoforms, and RNA modifications, enabling more accurate detection of disease-related transcriptional changes. We conducted high-throughput ONT long-read RNA sequencing on blood samples from 145 individuals, including PD patients and age-matched healthy controls. RNA libraries were prepared using a cDNA-based protocol optimised for high-accuracy PromethION sequencing. Transcriptomes were quantified with ONT-specific pipelines, and analyses of differential gene expression (DGE), differential transcript expression (DEX), differential transcript usage (DTU), and alternative splicing were performed using ONT-aware tools such as DRIMSeq, DEXSeq, and stageR. Pathway enrichment linked disease-related changes to mitochondrial, lysosomal, and vesicle-trafficking pathways. Our analysis identified highly significant PD-associated transcriptional signatures in peripheral blood (SNCA, VPS13C, LRRK2, GRN, STAU1, NPTN, PARK7). Long-read sequencing uncovered extensive isoform-level dysregulation, including novel transcript variants (e.g., BCL2L2-PABPN1, SQSTM1) in pathways relevant to PD, such as autophagy and endolysosomal trafficking. DTU analyses revealed shifts in isoforms of LRRK2 and GBA1, indicating widespread disturbances in RNA processing. Enrichment analysis showed activation of molecular pathways linked to neurodegeneration. This study provides the largest long-read blood transcriptomic dataset in PD to date, demonstrating that ONT sequencing can resolve isoform-level changes and reveal systemic molecular signatures of PD. Our findings support the development of blood-based RNA biomarkers and the establishment of long-read transcriptomics as a transformative approach for genomic pathology in PD.",

Although GABA has been associated with neurophysiological roles, product-specific clinical evidence for GABA-enriched frozen yogurt is not established. This review focuses on technological and engineering aspects rather than clinical efficacy. This review synthesizes recent advances in microbial biosynthesis and engineering strategies for producing high-quality GABA-frozen yogurt, including lactic acid bacteria strain selection (e.g., Levilactobacillus brevis, Lactiplantibacillus plantarum), fermentation optimization, and critical processing steps such as homogenization, aging, and dynamic freezing. Advanced technologies, including high-pressure processing, microfluidization, and the use of cryoprotectants, are discussed in relation to achieving target physicochemical properties. Target physicochemical properties for frozen yogurt systems typically include 35%-40% (w/w) total solids in the frozen yogurt mix and 20%-50% (v/v) overrun in the final frozen product, consistent with ranged reported for frozen yogurt and adjacent frozen dairy desserts; these values depend on formulation composition and processing conditions. Previous clinical trials and limited human studies suggest that GABA may contribute to anxiolytic and neuroprotective effects via the gut-brain axis; however, evidence specific to dairy-based delivery systems remains limited. Key challenges include maintaining GABA stability during frozen storage, scaling production, and navigating regulatory frameworks. Future perspectives highlight nanoencapsulation, synbiotic formulations, and computational modeling as tools to advance the development of GABA-enriched frozen yogurt as a functional dairy product supporting cognitive wellness.",
"42495768": "ID: 42495768\nTitle: Chronic kidney disease\u2011associated encephalopathy: Clinical features, pathomechanisms and emerging therapeutic strategies (Review).\nAbstract: Chronic kidney disease (CKD) is a progressive disorder whose systemic effects extend to the central nervous system, leading to CKD\u2011associated encephalopathy. Epidemiological data indicate that the prevalence of cognitive impairment in patients with CKD is as high as 40%, while mood disorders such as depression and anxiety exceed 60% among those receiving hemodialysis, and the risk of cerebrovascular events is also notably increased. These complications substantially impair the quality of life of patients, functional independence and long\u2011term prognosis, thereby constituting a considerable clinical burden. The key pathological mechanisms involve disruption of the 'gut\u2011kidney\u2011brain axis'. Declining renal function leads to the accumulation of gut microbiota\u2011derived uremic toxins, such as indoxyl sulfate, p\u2011Cresyl sulfate and trimethylamine N\u2011oxide. Through multiple pathways, including disruption of blood\u2011brain barrier integrity, induction of neuroinflammation, promotion of oxidative stress and direct neurotoxicity, these toxins collectively contribute to the injury of the neurovascular unit, neuronal dysfunction and even neurodegeneration. The present review systematically outlines the clinical manifestations, the aforementioned core pathogenic mechanisms and emerging therapeutic strategies for CKD\u2011associated encephalopathy. Clinically, early identification of neurological complications (such as through neuropsychological assessment, gait analysis and neuroimaging), along with monitoring of specific biomarkers, is crucial for timely intervention and improved prognosis. In terms of treatment, the targeted interventions on the gut\u2011kidney\u2011brain axis (such as specific probiotics and intestinal adsorbents), and the advantages and disadvantages of stem cells and gene therapy are summarized in the present review. A deeper understanding of these mechanisms will provide a solid theoretical foundation for the development of innovative treatments and ultimately improve neurological outcomes in patients with CKD.",
"42497020": "ID: 42497020\nTitle: Metabolic endotoxemia in metabolic and neurodegenerative diseases.\nAbstract: Metabolic diseases, which include obesity, type 2 diabetes, atherosclerosis, and metabolic dysfunction-associated steatotic liver disease (MASLD), are significant global health challenges. Patients with these conditions frequently exhibit gut dysbiosis and compromised gut barrier integrity, which lead to excessive translocation of Gram-negative bacterial lipopolysaccharide (LPS or endotoxin) from the gut lumen into the systemic circulation. This results in chronically elevated systemic LPS levels, a condition termed \"metabolic endotoxemia\". Gut-derived LPS may stimulate inflammatory responses and oxidative stress when it translocates and is recognized by host Toll-like receptor 4 (TLR4) and caspase-4/-5/-11. Metabolic endotoxemia is a primary trigger for the low-grade inflammation that promotes the development of metabolic diseases. Emerging evidence also indicates that metabolic endotoxemia acts as a key driver in the pathogenesis of neurodegenerative disorders, such as Alzheimer's disease, by promoting chronic neuroinflammation. In this review, we discuss: (1) the molecular structure of LPS that determines its bioactivity and its recognition by host cells, (2) host regulation of its bioactivity, (3) its translocation from the gut lumen into the systemic circulation, and (4) how metabolic endotoxemia contributes to obesity, type 2 diabetes, atherosclerosis, MASLD, and Alzheimer's disease. We conclude by exploring potential interventions aimed at preventing or mitigating metabolic endotoxemia by promoting LPS degradation and inactivation.",
"42499636": "ID: 42499636\nTitle: Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights.\nAbstract: This review summarizes the potential genes involved in both Parkinson's disease (PD) pathogenesis and colorectal cancer (CRC) carcinogenesis, focusing on the oncogenic mechanisms that may arise from PD gene dysfunctions. By investigating genes such as PRKN, PINK1, and DJ-1, which influence pathways primarily related to oxidative stress, mitophagy, cell cycle regulation, and inflammation, this review provides insight into how PD genes may contribute to CRC tumorigenesis through interactions with gut microbes such as Bacillus subtilis and Clostridium butyricum. This review highlights a mechanistic bridge between neurodegeneration and cancer centered on mitochondrial dysfunction, mitophagy, and inflammation. The convergence of molecular mechanisms and gut microbiota in PD and CRC highlights promising avenues for microbiome-targeted interventions alongside genetic and molecular approaches to advance novel diagnostic and therapeutic strategies for these two diseases. Importantly, therapeutic strategies should be considered in a holistic manner, as interventions for one disease may influence the course of another, and probiotics represent a unique modality with the potential to confer preventive and therapeutic benefits across both conditions.",
"42500659": "ID: 42500659\nTitle: Clinical advances and multifactorial pathophysiological mechanisms of neuropsychiatric comorbidity in systemic sclerosis.\nAbstract: This review addresses the high prevalence of depression and anxiety in systemic sclerosis (SSc), as well as the core biological, psychological and social mechanisms underlying such psychiatric comorbidities, The prevalence of clinically significant depression or anxiety disorders reaches 30%-50% among patients with SSc who satisfy corresponding diagnostic criteria. Established risk factors encompass multi-organ involvement (e.g., lung fibrosis, digital ulcers), chronic pain, physical disability and disease-related stigma. Three key pathophysiological mechanisms drive this comorbidity: immune dysregulation induces neuroinflammation via pro-inflammatory cytokines (IL-6, TNF-\u03b1), pathogenic autoantibodies and gut-brain axis disruption; cerebral microvascular damage and chronic hypoxia impair emotion-regulating neural circuits; tissue fibrosis and persistent stress over activate the HPA axis, forming a pathogenic cycle connecting systemic inflammation, glucocorticoid resistance and negative mood. Clinical management of SSc should extend beyond conventional antidepressants and cognitive behavioral therapy to include integrated rheumatology-psychiatry care, IL-6/JAK-targeted biologics and transcutaneous vagus nerve stimulation (tVNS), all designed to ameliorate patients' physical and psychiatric symptoms simultaneously. In conclusion, psychiatric comorbidity in SSc stems from the intricate interplay of biological, psychological and social factors. Elucidating these mechanisms facilitates the development of targeted therapeutic strategies that address both systemic SSc manifestations and associated mental health conditions, thereby enhancing patients' health-related quality of life and long-term psychiatric outcomes.",
"42501008": "ID: 42501008\nTitle: Targeting the microbiota-gut-brain axis in neurodegeneration: Zebrafish-based investigations.\nAbstract: The microbiota-gut-brain axis (MGBA) is a bidirectional signaling pathway regulated by the gut microbiome and the central nervous system (CNS). Moreover, MGBA is crucial for normal growth, development, and physiology of the brain and gut of the host; dysfunction in MGBA has been closely linked with the development of neurological disorders. Gut dysbiosis and its metabolites modulate barrier permeability and cause gastrointestinal tract (GIT) inflammation, which is followed by an increase in pro-inflammatory cytokines, immune cell infiltration into the brain, and vagus nerve dysfunction, resulting in neuroinflammation and neuronal defects in the brain, as well as some other behavioral defects. In this review, we will discuss the molecular and neurobehavioral properties of Zebrafish as a research model to study MGBA, as well as current discoveries in humans, highlighting the vital role of MGBA in neuropathological conditions. Using Zebrafish as a genetic model in combination with in vivo imaging technology may suggest some novel mechanisms for the interaction between gut microbiota and CNS, particularly in the case of neurological disorders including Alzheimer's disease (AD), Parkinson's disease (PD) and autism spectrum disorder (ASD). A comprehensive literature search was conducted using electronic databases including PubMed, Scopus, Web of Science, and Google Scholar.",
"42501862": "ID: 42501862\nTitle: The gut microbiota metabolite IAA modulates gut-brain axis to alleviate reproductive endocrine dysfunction in PCOS.\nAbstract: Circadian rhythm disruption (CD) and gut microbiota dysbiosis are emerging drivers of the polycystic ovary syndrome (PCOS). However, the specific microbial metabolites mediating the gut-brain-ovary axis remain poorly defined, limiting the development of targeted microecological therapies. We aimed to identify the functional role of the gut microbiota-derived metabolite indole-3-acetic acid (IAA) in PCOS, dissecting its peripheral and central mechanisms in ameliorating reproductive-endocrine phenotypes. Multi-omics analyses of clinical PCOS cohorts (feces, serum, follicular fluid) were integrated with CD and DHEA-induced rodent models. Mechanistic pathways were dissected using microbiota-depleted (ABX) models, pharmacokinetic profiling, in vivo chemogenetics via Fos-CreERT2 transgenic mice, and gene silencing (Clock siRNA) in vitro, combined with histological and immunological evaluations. We established the essential role of the gut microbiota in development of CD-induced PCOS phenotypes in rats. Integrating this finding with multi-omics profiling, we identified a profound impairment in indole biosynthesis, characterized by significantly diminished serum IAA levels in both PCOS rat models and clinical patients. Exogenous IAA supplementation across multiple PCOS rodent models ameliorated hyperandrogenism, restored estrous cyclicity, and improved ovarian pathology. Mechanistically, IAA exerted an integrated protective effect across the gut-brain axis. Locally, IAA reinforced intestinal barrier integrity via a CLOCK-dependent pathway, restricting lipopolysaccharide (LPS) translocation and systemic inflammation. Concurrently, IAA treatment suppressed the pathological hyperactivity of ventromedial hypothalamus (VMH) neurons. Crucially, the therapeutic efficacy of IAA was neutralized in microbiota-depleted models, indicating that its restorative function is fundamentally contingent upon a pre-existing dysbiotic context. Our study suggests that the gut microbiota plays a pivotal role in mediating CD-induced PCOS-like phenotypes. IAA functions as a crucial microbial mediator that alleviates PCOS by concurrently restoring peripheral intestinal barriers, dampening systemic inflammation, and rectifying central VMH neuroendocrine hyperactivity. These findings highlight IAA as a microbiota-dependent precision modulator for resetting the gut-brain-ovary axis in PCOS.",
"42503985": "ID: 42503985\nTitle: [Morphology and anatomical variations of the left gastric vein].\nAbstract: Objective: To explore the gross morphology and variation characteristics of the left gastric vein (LGV) by means of cadaveric anatomical measurement and three-dimensional imaging reconstruction. Methods: A total of 39 adult cadaver specimens fixed with 4% formaldehyde solution from Zhongshan School of Medicine, Sun Yat-sen University, and 40 cases of abdominal contrast-enhanced CT imaging data of patients with gastric cancer admitted to the Seventh Affiliated Hospital of Sun Yat-sen University between January 2023 and December 2024 were included in this study. Specimens with obvious decomposition, tissue deformation, structural damage, or a history of upper abdominal surgery were excluded; patients with pathologically confirmed gastric cancer and CT images suitable for three-dimensional vascular reconstruction were selected, while those complicated with liver cirrhosis, portal hypertension, or a history of major upper abdominal surgery were excluded. The perigastric and perihepatic vessels were exposed in cadaver specimens to observe the morphology and course of the LGV and measure related anatomical parameters; the imaging data were scanned with dual-source CT using standardized parameters, and three-dimensional vascular reconstruction was performed on a post-processing workstation. The LGV was classified according to the Lee criteria. Results: Cadaveric dissection showed that the LGV originated from the middle of the lesser curvature of the stomach, coursed leftward along the lesser curvature, received 2-3 esophageal veins at the inferior margin of the esophageal hiatus, and then obliquely descended rightward to drain into the hepatic portal vein. Both cadaveric dissection and imaging detected three drainage sites of the LGV: the hepatic portal vein, the portal vein angle, and the splenic vein. CT angiography (coronal plane) and cadaver specimens both showed that the proportion of drainage into the hepatic portal vein was the highest [52.5% (21/40) vs. 53.8% (21/39)], followed by the splenic vein [35.0% (14/40) vs. 41.0% (16/ 39)], and the least common was drainage into the portal vein angle [12.5% (5/40) vs. 5.1% (2/39)]. The length of the LGV was (40.3\u00b17.4) mm in cadaver specimens and (48.4\u00b111.9) mm on imaging; the distance from the drainage site to the portal vein angle was (13.8\u00b18.1) mm in cadaver specimens and (13.1\u00b18.2) mm on imaging. In both the imaging group and the cadaver group, the type Ip accounted for the highest proportion of LGV classification, at 40.0% (16/40) and 41.0% (16/39), respectively, and no type IV was detected in either group. The proportion of type II in the imaging group was 22.5% (9/40), which was higher than that in the cadaver group (7.7%, 3/39); the proportion of type Ia in the cadaver group was 25.6% (10/39), which was higher than that in the imaging group (15.0%, 6/40); the proportions of type IIIa (20.0% in the imaging group vs. 20.5% in the cadaver group) and type IIIp (2.5% in the imaging group vs. 5.1% in the cadaver group) were similar between the two groups. Conclusions: There are certain variations in the anatomical course and diameter of the LGV. The LGV most commonly drains into the hepatic portal vein, and is mainly classified as type I. \u76ee\u7684\uff1a \u91c7\u7528\u5c38\u4f53\u89e3\u5256\u5b66\u6d4b\u91cf\u4e0e\u5f71\u50cf\u5b66\u4e09\u7ef4\u91cd\u5efa\u7684\u65b9\u6cd5\uff0c\u63a2\u7a76\u80c3\u5de6\u9759\u8109\u5927\u4f53\u5f62\u6001\u548c\u53d8\u5f02\u7279\u70b9\u3002 \u65b9\u6cd5\uff1a \u672c\u7814\u7a76\u7eb3\u5165\u4e2d\u5c71\u5927\u5b66\u4e2d\u5c71\u533b\u5b66\u9662\u768439\u5177\u7ecf4%\u7532\u919b\u6eb6\u6db2\u56fa\u5b9a\u7684\u6210\u4eba\u5c38\u4f53\u6807\u672c\u4ee5\u53ca\u4e2d\u5c71\u5927\u5b66\u9644\u5c5e\u7b2c\u4e03\u533b\u9662\u4e8e2023\u5e741\u6708\u81f32024\u5e7412\u6708\u671f\u95f4\u6536\u6cbb\u768440\u4f8b\u80c3\u764c\u60a3\u8005\u8179\u90e8\u589e\u5f3aCT\u5f71\u50cf\u8d44\u6599\u3002\u6807\u672c\u6392\u9664\u8150\u8d25\u53d8\u5f62\u3001\u7ed3\u6784\u635f\u6bc1\u53ca\u6709\u4e0a\u8179\u90e8\u624b\u672f\u53f2\u8005\uff1b\u60a3\u8005\u9009\u53d6\u75c5\u7406\u786e\u8bca\u80c3\u764c\u3001CT\u56fe\u50cf\u53ef\u5b8c\u6210\u8840\u7ba1\u4e09\u7ef4\u91cd\u5efa\u75c5\u4f8b\uff0c\u6392\u9664\u5408\u5e76\u809d\u786c\u5316\u3001\u95e8\u9759\u8109\u9ad8\u538b\u53ca\u4e0a\u8179\u90e8\u91cd\u5927\u624b\u672f\u53f2\u8005\u3002\u5bf9\u5c38\u4f53\u6807\u672c\u89e3\u5256\u66b4\u9732\u80c3\u5468\u53ca\u809d\u5468\u8840\u7ba1\uff0c\u89c2\u5bdf\u80c3\u5de6\u9759\u8109\u5f62\u6001\u8d70\u884c\u5e76\u6d4b\u91cf\u76f8\u5173\u89e3\u5256\u53c2\u6570\uff1b\u5f71\u50cf\u5b66\u8d44\u6599\u91c7\u7528\u53cc\u6e90CT\u89c4\u8303\u53c2\u6570\u626b\u63cf\uff0c\u7ecf\u540e\u5904\u7406\u5de5\u4f5c\u7ad9\u884c\u8840\u7ba1\u4e09\u7ef4\u91cd\u5efa\u3002\u53c2\u7167Lee\u6807\u51c6\u5bf9\u80c3\u5de6\u9759\u8109\u8fdb\u884c\u5206\u578b\u3002 \u7ed3\u679c\uff1a \u5c38\u4f53\u6807\u672c\u89e3\u5256\u663e\u793a\uff0c\u80c3\u5de6\u9759\u8109\u59cb\u4e8e\u80c3\u5c0f\u5f2f\u4e2d\u90e8\uff0c\u6cbf\u80c3\u5c0f\u5f2f\u5de6\u884c\uff0c\u4e8e\u98df\u7ba1\u88c2\u5b54\u4e0b\u7f18\u6536\u7eb32~3\u6761\u98df\u7ba1\u9759\u8109\uff0c\u7ee7\u800c\u5411\u4e0b\u659c\u884c\u5411\u53f3\u6c47\u5165\u809d\u95e8\u9759\u8109\u3002\u5c38\u4f53\u89e3\u5256\u548c\u5f71\u50cf\u5b66\u5747\u6d4b\u5f97\u80c3\u5de6\u9759\u8109\u6c47\u5165\u70b9\u4f4d\u7f6e\u6709\uff1a\u809d\u95e8\u9759\u8109\u3001\u95e8\u9759\u8109\u89d2\u3001\u813e\u9759\u8109\u3002CT\u8840\u7ba1\u5f71\u50cf\uff08\u51a0\u72b6\u9762\uff09\u548c\u5c38\u4f53\u6807\u672c\u5747\u663e\u793a\uff0c\u6c47\u5165\u809d\u95e8\u9759\u8109\u7684\u6bd4\u4f8b\u6700\u9ad8\uff3b\u5206\u522b\u4e3a\uff1a52.5%\uff0821/40\uff09\u300153.8%\uff0821/39\uff09\uff3d\uff0c\u5176\u6b21\u662f\u813e\u9759\u8109\uff3b\u5206\u522b\u4e3a\uff1a35.0%\uff0814/40\uff09\u300141.0%\uff0816/39\uff09\uff3d\uff0c\u6700\u5c11\u6c47\u5165\u5230\u95e8\u9759\u8109\u89d2\uff3b\u5206\u522b\u4e3a\uff1a12.5%\uff085/40\uff09\u30015.1%\uff082/39\uff09\uff3d\u3002\u80c3\u5de6\u9759\u8109\u7684\u5c38\u4f53\u6807\u672c\u957f\u5ea6\uff0840.3\u00b17.4\uff09mm\uff0c\u5f71\u50cf\u5b66\u4e3a\uff0848.4\u00b111.9\uff09mm\uff0c\u6c47\u5165\u70b9\u4e0e\u95e8\u9759\u8109\u89d2\u8ddd\u79bb\uff0813.8\u00b18.1\uff09mm\uff0c\u5f71\u50cf\u5b66\u4e3a\uff0813.1\u00b18.2\uff09mm\u3002\u5f71\u50cf\u7ec4\u4e0e\u5c38\u4f53\u6807\u672c\u7ec4\u80c3\u5de6\u9759\u8109\uff08\u80c3\u5de6\u9759\u8109\uff09\u5206\u578b\u5747\u4ee5\u2160p\u578b\u5360\u6bd4\u6700\u9ad8\uff0c\u5206\u522b\u4e3a40.0%\uff0816/40\uff09\u4e0e41.0%\uff0816/39\uff09\uff0c\u4e14\u5747\u672a\u68c0\u51fa\u2163\u578b\u3002\u5f71\u50cf\u7ec4\u4e2d\u2161\u578b\u5360\u6bd4\u4e3a22.5%\uff089/40\uff09\uff0c\u9ad8\u4e8e\u6807\u672c\u7ec4\u76847.7%\uff083/39\uff09\uff1b\u800c\u2160a\u578b\u5360\u6bd4\u5728\u6807\u672c\u7ec4\u4e3a25.6%\uff0810/39\uff09\uff0c\u9ad8\u4e8e\u5f71\u50cf\u7ec4\u768415.0%\uff086/40\uff09\uff1b\u4e24\u7ec4\u95f4\u2162a\u578b\uff08\u5f71\u50cf\u7ec420.0%\u3001\u6807\u672c\u7ec420.5%\uff09\u4e0e\u2162p\u578b\uff08\u5f71\u50cf\u7ec42.5%\u3001\u6807\u672c\u7ec45.1%\uff09\u5360\u6bd4\u76f8\u8fd1\u3002 \u7ed3\u8bba\uff1a \u80c3\u5de6\u9759\u8109\u89e3\u5256\u8d70\u884c\u53ca\u7ba1\u5f84\u5b58\u5728\u4e00\u5b9a\u53d8\u5f02\uff0c\u80c3\u5de6\u9759\u8109\u6c47\u5165\u809d\u95e8\u9759\u8109\u6bd4\u4f8b\u6700\u9ad8\uff0c\u5206\u578b\u4ee5\u2160\u578b\u4e3a\u4e3b\u3002.",

Chebulinic acid (CA), a polyphenolic compound from Terminalia chebula, exhibits potent antioxidant and anti-inflammatory properties against UVB-induced skin damage. However, its large molecular weight hinders transdermal delivery and the TAT47-57 peptide (core of HIV-1 TAT) enables rapid transmembrane transport. Large particles with double-layer membrane structure and a diameter exceeding 1000 nm were obtained during the separation of plant-derived exosome-like nanoparticles (PELNs), which are not considered as PELNs (50-500 nm), after a mixture with TAT anchored to the surface of engineered artificial vesicles (EAVs) and extrusion causes membrane fusion, employed as novel nanocarriers to overcome the difficulty in skin penetration by leveraging their lipid bilayer structure and surface membrane-anchored TAT for efficient epidermal fusion and intercellular penetration. Furthermore, CA-loaded TAT-ePELNs demonstrate significant efficacy in mitigating UVA-induced photoaging. Collectively, this study expands the anti-UVR damage application spectrum of CA from UVB to UVA exposure and establishes a green, efficient, and biosafe strategy for transdermal drug delivery by utilization of non-PELNs generated during the preparation process of PELNs.",
"42505396": "ID: 42505396\nTitle: Mediterranean Diet and Neurodegenerative Diseases: Recent Advances from the Gut-Immune-Brain Axis to Multi-Omics-Guided Precision Nutrition.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD) and Parkinson's disease (PD) are regarded as systemic illnesses, mainly characterized by long-term neuroinflammation, metabolic dysregulation and barrier dysfunction. All these factors interact through the gut-immune-brain axis. The Mediterranean diet, rich in plant-based foods, olive oil, and fish, has been consistently associated with slower cognitive decline and reduced risk of neurodegeneration in observational studies and some clinical trials. This review provides a systems-level synthesis that distinguishes itself from previous narratives by integrating disease-specific mechanistic frameworks with multi-omics-guided precision nutrition strategies. We summarize recent evidence showing that this dietary pattern can remodel gut microbiota composition and enhance the production of bioactive metabolites such as short-chain fatty acids (SCFAs). These metabolites are associated with improved intestinal barrier integrity, reduced systemic inflammation, and potential modulation of brain functions. Within the central nervous system, diet-related metabolites have been linked to reduced neuroinflammation via modulation of microglial and astrocytic states. They have been linked to protection of mitochondrial function, maintenance of proteostasis, and preservation of blood-brain barrier (BBB) integrity. In AD and PD patients, adherence to this diet is associated with favorable changes in pathological hallmarks, including amyloid-beta (A\u03b2), tau, and \u03b1-synuclein accumulation. Nowadays, multi-omics tools, including single-cell transcriptomics, spatial transcriptomics and microbiome analysis, are widely used in this field, which helps researchers explore these complicated effects more deeply. Importantly, individual responses to the diet vary considerably due to differences in genetic background, gut microbial composition, and metabolic phenotypes, which underscore the need to move from generalized dietary guidelines toward personalized precision nutrition. The Mediterranean diet is not only a dietary pattern but also an effective way to modulate neuro-immune and metabolic networks. However, current evidence remains largely observational, and we critically discuss the need for more randomized controlled trials (RCTs) and standardized multi-omics data analysis frameworks. To sum up, the Mediterranean diet plays a neuroprotective role via the gut-immune-brain axis, and multi-omics techniques promote the development of precision nutrition. More trials and improved multi-omics systems are required to apply these research results in clinical practice.",
"42505588": "ID: 42505588\nTitle: The Microbiota as a Potential Cause of Disease.\nAbstract: Background: The human microbiota plays a crucial role in maintaining physiological homeostasis and influencing the development of chronic diseases not only in the gut but in the whole body. Material and Methods: This literature review is based on a comprehensive search of the PubMed database covering the period from 2008 to 2026. Approximately 65 key studies were included in the final analysis. Only articles published in English were included. The search included keywords such as microbiota, inflammaging, eubiosis, diet, gut diseases, cardiovascular diseases, diabetes, and osteoporosis. This narrative review explores the composition, development, and functional significance of the gut microbiota across the human lifespan, highlighting its dynamic interaction with environmental factors. Early-life microbial colonization, shaped by factors including delivery mode and breastfeeding, has long-term implications for immune system maturation and disease susceptibility. Results: A balanced gut microbiota (eubiosis) supports host health through metabolic activities, mainly by the production of short-chain fatty acids (SCFAs), which regulate intestinal barrier integrity, immune responses, and systemic inflammation. Contrarily, dysbiosis-characterized by reduced microbial diversity and an overrepresentation of pro-inflammatory species-is associated with chronic low-grade inflammation (inflammaging) and contributes to the pathogenesis of multiple diseases. Age-related changes in microbial composition are shown to activate inflammatory processes and impair immune regulation, thereby increasing disease risk. Therefore, it is important to recognize the role of microbiota alterations in key pathological conditions, including neurodegenerative diseases, cardiovascular diseases, type 2 diabetes mellitus, and osteoporosis. Conclusions: Finally, the potential of microbiome-targeted interventions, such as probiotics, prebiotics, and dietary modulation-in particular the Mediterranean diet is recognized as the most balanced-is discussed as a promising strategy to restore microbial balance and mitigate inflammaging. Further research is needed to better understand the association between microbiota and host health and to optimize therapeutic approaches for aging populations.",
"42506336": "ID: 42506336\nTitle: The Gut Microbiota in Addiction Biology: A Systematic Review of Substance-Induced Dysbiosis and Gut-Brain Axis Alterations.\nAbstract: Growing evidence suggests that chronic substance use disrupts the gut microbiota composition and function, which can contribute to intestinal dysfunction, systemic inflammation, and gut-brain axis dysregulation. However, current evidence remains fragmented and heterogenous, with most studies focusing on individual substances rather than substance-specific microbial signatures. Therefore, this systematic review synthesizes recent evidence (2019-2025) to characterize the impact of chronic substance use, including alcohol, nicotine, opioids, cocaine, and methamphetamine, on the gut microbiota composition and functional integrity. Following the PRISMA 2020 guidelines, a total of 91,421 records were identified before screening through searches conducted across electronic databases and publisher platforms, including PubMed, Web of Science, ProQuest, and BSCOhost, among others. After duplication removal and application of the predefined eligibility criteria, 60 studies were selected for qualitative analysis. The findings revealed an interspecies similarity in which chronic substance exposure generally induced dysbiosis characterized by a depletion of beneficial short-chain fatty acid (SCFA)-producing taxa, such as Lactobacillus, Akkermansia, and Faecalibacterium, alongside the enrichment of opportunistic pathogens such as Escherichia-Shigella. Alcohol emerged as a particularly potent ecological driver, consistently reducing the richness and diversity of the microbial community. Mechanistically, these alterations are linked to impaired intestinal barrier function, increased lipopolysaccharide translocation, and the activation of systemic inflammatory pathways. Furthermore, substance-specific metabolic fingerprints were identified, including disruptions in glutamate pathways for cocaine and trimethylamine N-oxide precursors for methamphetamine. Preclinical evidence from fecal microbiota transplantation and germ-free models suggests that these microbial shifts actively modulate reward sensitivity and neuroplasticity through the gut-brain axis. Collectively, the data presented in this study support a shift from reductionist addiction models toward a systems-level framework, positioning the gut microbiome as a pivotal, modifiable component of addiction biology and a promising target for novel therapeutic interventions.",
"42508392": "ID: 42508392\nTitle: Targeting the Microbiota-Butyrate-BHB Axis As a Potential Metabolic Therapeutic Strategy for Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is increasingly linked to metabolic and microbial dysregulations, with butyrate and \u03b2-hydroxybutyrate (BHB) identified as key modulators. BHB is a ketone body primarily produced by the liver during periods of low glucose availability, and BHB levels are reduced in the AD brain and peripheral blood. Butyrate, a microbiota-derived short-chain fatty acid, is also reduced in the peripheral blood in association with gut microbiota dysbiosis. The reduction of butyrate and BHB, together with gut microbiota dysbiosis, is commonly observed in AD patients and correlates with cognitive decline and AD-related pathologies. Reduced levels of butyrate and BHB may impair energy metabolism, exacerbating amyloid-beta (A\u03b2) and tau pathologies. In contrast, preliminary evidence from interventional and ketogenic studies suggests that increasing butyrate and BHB levels may attenuate AD-related pathologies, such as A\u03b2 and tau abnormalities, while improving cognitive function. Emerging evidence suggests that both butyrate and BHB can cross the blood-brain barrier (BBB), suppressing oxidative stress and pro-inflammatory cytokines and potentially mitigating A\u03b2 aggregation and tau hyperphosphorylation. Accordingly, therapeutic strategies targeting the microbiota-butyrate-BHB axis represent a promising and biologically plausible approach that warrants further rigorous clinical investigation for the prevention and treatment of AD. This review comprehensively examines the roles of butyrate and BHB in ameliorating key AD-related pathologies, including A\u03b2 aggregation, tau hyperphosphorylation, neuroinflammation, and neurodegeneration. Additionally, the review explores the bidirectional association between butyrate/BHB and gut dysbiosis in AD, including how dysbiosis reduces butyrate/BHB levels while elevating them may reverse dysbiosis and improve gut-brain axis function. Collectively, these findings suggest that butyrate and BHB emerge as promising candidates for potential novel adjunctive therapies for AD, although supporting human evidence remains preliminary and heterogeneous.",
"42510550": "ID: 42510550\nTitle: Is Ergothioneine an Important Source of Plasma Trimethylamine N-Oxide in Humans?\nAbstract: High circulating levels of trimethylamine-N-oxide (TMAO), largely produced by hepatic oxidation of gut-microbiota-derived trimethylamine (TMA), are associated with increased risk of cardiometabolic and neurodegenerative diseases. In contrast, the diet-derived compound ergothioneine (ET) possesses cytoprotective and neuroprotective properties, and higher circulating ET levels have been linked to a lower risk of cardiovascular, neurodegenerative, and other age-related disorders. However, concerns have been raised that microbial degradation of ET may also contribute to the TMAO pool. In this study, we examined the relationship between ET and TMAO. Bioinformatic analyses indicated that ergothionase, the enzyme responsible for ET degradation to trimethylamine (TMA), is restricted to a limited number of bacterial genera and is far less prevalent than choline trimethylamine lyase, which generates TMA from choline. In a randomised, placebo-controlled human study, ET supplementation (25 mg/day for 7 days) significantly increased plasma ET levels but did not increase TMAO concentrations. Similarly, in a heart failure cohort, plasma ET showed no correlation with TMA or TMAO levels, whereas TMAO was clearly correlated with TMA. Collectively, these findings suggest that ET is unlikely to contribute significantly to systemic TMAO levels.",

Probiotics have emerged as promising microecological interventions, yet marked strain-specific efficacy and incomplete mechanistic understanding hinder clinical translation. This review systematically synthesizes evidence from human randomized controlled trials, animal studies, and mechanistic investigations on probiotic interventions for constipation. We catalog major anti-constipation strains across Bifidobacterium, Lactobacillus, Bacillus, and other genera, and summarize key findings from published meta-analyses indicating that B. coagulans improves stool consistency by 52.8%, L. paracasei demonstrates 86.3% effectiveness for incomplete defecation severity and 87.6% for PAC-SYM, while L. reuteri achieves 99.9% effectiveness on PAC-QoL. Mechanistically, probiotics act through four synergistic pathways: gut microbiota modulation, metabolite-mediated actions centered on SCFAs and 5-HT-with strains harboring the abfA gene cluster exhibiting enhanced arabinan utilization for sustained metabolite production-gut-brain axis neuro regulation, and dynamic mucosal barrier restoration. Finally, we propose a systematic four-stage screening pipeline integrating genomic pre-screening, probiotic property evaluation, in vitro functional prediction, and in vivo multi-tiered validation. This review provides a comprehensive framework for evidence-based strain selection and personalized probiotic therapy in constipation management.",

Leaf-Derived Exosome-like Nanoparticles in ETEC-Challenged IPEC-J2 Cells.\nAbstract: Safflower (Carthamus tinctorius L.) is a cash crop grown worldwide. Its seeds and flowers are primarily processed for edible oil and medicinal raw materials, while stems and leaves are discarded as agricultural waste. Recently, plant-derived exosome-like nanoparticles (PELNs) have gained growing research interest in food nutrition owing to their exceptional biocompatibility and relatively low cost for large-scale production. This study aimed to explore the potential functional value of safflower leaf agricultural waste by isolating safflower-derived PELNs. Firstly, a protocol was established for the isolation and purification of safflower (Carthamus tinctorius L.)-derived exosome-like nanoparticles (Ct-ELNs) from safflower leaves using sucrose density gradient ultracentrifugation. NTA analysis revealed that the 30-45% sucrose fraction enriched with Ct-ELNs exhibited the most uniform particle size, highest particle concentration, and optimal purity. Transmission electron microscopy confirmed typical PELNs ultrastructure: disc- or cup-shaped vesicles surrounded by bilayer lipid membranes. FM4-64 fluorescence suggests time-dependent association and likely cellular uptake of labeled Ct-ELNs by IPEC-J2 cells. Cellular assays demonstrated that Ct-ELNs elevated IPEC-J2 cell metabolic activity under matched protein-normalized dosing conditions. The 30-45% sucrose fraction showed the most favorable physicochemical profile and preliminary in vitro protective effects, including improved IPEC-J2 cell metabolic activity and modulation of Enterotoxigenic Escherichia coli (ETEC)-induced inflammation-related gene expression. Overall, this study established an optimized isolation protocol for Ct-ELNs derived from safflower leaves. These data indicate that safflower-derived Ct-ELNs confer preliminary cytoprotective transcriptional regulatory effects on intestinal epithelial cells under in vitro culture conditions.",
"42511198": "ID: 42511198\nTitle: Camel Milk Alleviates Chronic Fatigue Syndrome-like Symptoms in Mice by Modulating the Small Intestinal Microbiota and Inflammation.\nAbstract: This study aimed to investigate the therapeutic effects of camel milk (CM) on chronic fatigue syndrome (CFS) and elucidate the mechanisms underlying the microbiota-gut-brain axis. Using a murine model of CFS induced by chronic restraint and forced swimming stress, we administered lyophilized CM (1500 mg/kg/day, equivalent to approximately 121.5 mg/kg/day in humans based on body surface area conversion using the standard allometric scaling formula) orally. CM supplementation was significantly associated with ameliorated fatigue-like behaviors, as evidenced by prolonged swimming endurance and reduced immobility time. Metagenomic analysis revealed that CM was associated with reshaping of the small intestinal microbiota, including enrichment of beneficial Lactococcus lactis and suppression of pathobionts (H. hepaticus and H. typhlonius). These microbial shifts correlated with increased luminal lactic acid, improved intestinal barrier integrity (increased villus height, reduced crypt depth), and attenuated local inflammation (reduced TNF-\u03b1 and IL-6, elevated IL-10). Consequently, CM was associated with reduced bacterial translocation and systemic inflammation, and normalization of hypothalamic-pituitary-adrenal (HPA) axis hyperactivity. We conclude that CM is associated with prevention of CFS-like symptoms through modulation of the gut ecosystem and strengthening of the intestinal barrier, potentially breaking the vicious cycle of gut inflammation and HPA axis dysfunction, although causality remains to be established through fecal microbiota transplantation or similar mechanistic studies.",
"42511672": "ID: 42511672\nTitle: Disulfidptosis-Associated Neurotoxicity Induced by Cadmium Under an Environmentally Relevant Cadmium Exposure Scenario.\nAbstract: Cadmium (Cd) is a widespread environmental pollutant associated with neurotoxicity, but its underlying mechanisms remain unclear. Disulfidptosis is a regulated cell death driven by disulfide stress under conditions of impaired cellular reducing capacity. This study investigated the potential involvement of disulfidptosis-associated molecular alterations in Cd-induced neurotoxicity. Male Sprague Dawley (SD) rats were exposed to cadmium chloride (Low-Dose Group: CdCl2: 0.036 mg/kg bw; High-Dose Group: CdCl2: 3.6 mg/kg bw) by oral gavage for 30 days. Neurobehavioral performance was assessed using the open field test, elevated plus maze, and Morris water maze. Hippocampal ultrastructure, redox-related metabolites, and disulfidptosis-associated genes were analyzed. In addition, bioinformatics analysis was performed by integrating cadmium-related, neurodegenerative disease-related, and disulfidptosis-related genes. The results showed that high-dose Cd exposure impaired locomotor activity, increased anxiety-like behavior, and disrupted spatial learning and memory (p < 0.05), accompanied by mitochondrial damage in hippocampal neurons. Bioinformatics analysis identified seven overlapping genes and enrichment of ferroptosis and oxidative phosphorylation pathways. Biochemically, cadmium exposure significantly increased the NADP+/NADPH ratio ([Control: 1.07 \u00b1 0.044] vs. [High-dose: 3.80 \u00b1 0.059], p < 0.05) and decreased the GSH/GSSG ratio ([Control: 2.80 \u00b1 0.059] vs. [High-dose: 1.14 \u00b1 0.091], p < 0.05), indicating severe redox imbalance. At the molecular level, cadmium exposure upregulated SLC7A11 mRNA expression by 1.48 \u00b1 0.12-fold (p < 0.01) and SLC3A2 by 1.91 \u00b1 0.55-fold (p < 0.05), while downregulating NDUFS1 expression to 0.84 \u00b1 0.01-fold of control levels (p < 0.01) in hippocampal tissues. These findings suggest that high-dose Cd exposure induced neurotoxicity is associated with mitochondrial dysfunction, redox imbalance, and disulfidptosis-associated molecular alterations.",

Although heavy metals and pesticides act through distinct primary mechanisms, increasing evidence indicates that they converge on a common network of mitochondrial dysfunction characterized by oxidative stress, impaired metabolite transport, calcium dyshomeostasis, and sensitization to mitochondrial permeability transition. This review provides an updated overview of the major mitochondrial transport systems involved in environmental toxicity, including the adenine nucleotide translocator (ANT), phosphate carrier (PiC), mitochondrial calcium uniporter (MCU), voltage-dependent anion channel (VDAC), and F1\u00b7Fo-ATP synthase (ATP synthase). We discuss their physiological roles, the molecular mechanisms by which heavy metals and pesticides disrupt their function, and the effects on oxidative phosphorylation, reactive oxygen species (ROS) generation, cardiolipin remodeling, and mitochondrial membrane integrity. Particular attention is devoted to the debate surrounding the molecular basis of mitochondrial permeability transition pore (mPTP) formation and to the concept that permeability transition represents the integrated outcome of cumulative mitochondrial stress rather than dysfunction of a single protein. Finally, we summarize emerging therapeutic strategies aimed at preserving mitochondrial transport function, limiting mitochondrial permeability transition, and attenuating downstream inflammatory signaling. Understanding these convergent mechanisms may facilitate the development of interventions to mitigate chronic diseases associated with environmental toxicant exposure.",

By dissipating the proton-motive force generated by oxidative phosphorylation, UCP1 converts stored chemical energy into heat and enables adaptive thermogenesis during cold exposure. The rediscovery of metabolically active brown adipose tissue (BAT) and inducible beige adipocytes in adult humans has renewed interest in UCP1-positive thermogenic adipose tissue as a regulator of systemic metabolism and a potential target for therapeutic modulation in obesity and cardiometabolic disease. Beyond thermogenesis, accumulating evidence indicates that UCP1-positive brown/beige adipocytes and thermogenic adipose tissue are involved in lipid and glucose metabolism, mitochondrial redox homeostasis, inflammatory remodeling, organ protection, and tumor-associated metabolic adaptation, mainly through adipocyte-autonomous mechanisms and adipose-organ communication. However, UCP1 biology is complex: BAT activity measured by imaging does not directly quantify UCP1 proton conductance, non-adipose UCP1 expression is often low and technically challenging to validate, local cell-autonomous UCP1 function in non-adipose tissues remains controversial, and UCP1-independent thermogenic pathways may compensate in selected contexts. In this review, we summarize the molecular and structural basis of UCP1 function, its regulation at transcriptional and post-transcriptional levels, and its biological roles in cellular and systemic homeostasis, with explicit distinction between direct adipocyte-autonomous UCP1 functions, indirect systemic effects mediated by thermogenic adipose tissue, and preliminary or incompletely validated evidence of local UCP1 activity in non-adipose cells. We further discuss the association of UCP1-positive thermogenic adipose tissue with obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease, kidney injury, liver disease, neurological disorders, and cancer. Finally, we evaluate UCP1-related thermogenic adipose tissue activity as a biomarker and therapeutic target, highlighting current limitations, safety concerns, and future directions for precision metabolic medicine.",
"42511861": "ID: 42511861\nTitle: The Molecular and Cellular Mechanisms of Melatonin: From Physiological Actions to Clinical Applications in Reproductive Medicine.\nAbstract: Melatonin has evolved from its classical role as a pineal-derived circadian regulator to a molecule increasingly recognized for its mitochondrial and cytoprotective functions. This review examines the molecular mechanisms and translational implications of melatonin within a mitochondria-centered framework, with particular emphasis on reproductive medicine. Available evidence suggests that melatonin may influence mitochondrial quality control (MQC) through multiple interconnected processes, including ROS regulation, mitochondrial dynamics, mitophagy, biogenesis, and mitochondrial inflammatory signaling. In mitochondria, melatonin can attenuate electron transport chain-derived oxidative stress through direct radical-scavenging reactions, antioxidant metabolite formation, and indirect activation of endogenous antioxidant systems. Experimental studies further suggest that melatonin may modulate Drp1-mediated fission, OPA1- and Mfn1/2-associated fusion, PINK1/Parkin-mediated mitophagy, and SIRT1/PGC-1\u03b1-related mitochondrial biogenesis. In reproductive medicine, melatonin has been investigated as a potential adjunctive strategy in assisted reproductive technology, endometriosis, and polycystic ovary syndrome. However, clinical evidence remains heterogeneous, and most human studies have evaluated reproductive or biochemical outcomes rather than direct MQC-related biomarkers. Therefore, although melatonin represents a promising mitochondria-targeted adjunct, standardized dosing strategies, tissue-level pharmacodynamic assessment, and validated mitochondrial biomarkers are needed to determine whether these mechanisms translate into reproducible clinical benefit.",

Few studies have simultaneously assessed systemic inflammatory markers and gut microbiota composition within the same cohort while accounting for metabolic confounders. Moreover, data from Middle Eastern and North African (MENA) populations remain limited, restricting our understanding of how diet may influence neuroimmune-microbiome interactions in depression. This study aimed to investigate associations between MDD, systemic inflammatory markers, and gut microbiota composition in Lebanese adults. To our knowledge, this is the first study of its kind in Lebanon, as well as in the MENA region. In this cross-sectional case-control study, we examined circulating inflammatory markers and gut microbial profiles in 46 adults with DSM-5-confirmed MDD and 25 healthy controls. Plasma C-reactive protein (CRP) and interleukin-6 (IL-6) were measured, and the gut microbiota composition was characterized using 16S rRNA gene sequencing. Multivariable models were adjusted for age, sex, body mass index (BMI), Mediterranean diet adherence, and fluoxetine exposure. Depression status was not independently associated with CRP or IL-6 after adjustment, whereas BMI emerged as a significant determinant of systemic inflammation. At the genus level, MDD was associated with the enrichment of Dorea, Lachnoclostridium, Collinsella, Bilophila, and Klebsiella and the depletion of Christensenella, Mitsuokella, and Victivallis, independent of inflammatory biomarkers. Alpha diversity did not differ between groups, while beta diversity showed modest metric-dependent differences, primarily driven by presence/absence-based measures. Specific microbial taxa may contribute to gut-brain signaling pathways implicated in MDD and systemic inflammation. Further longitudinal and mechanistic studies are required to clarify causal interactions within inflammation-microbiome networks in MDD.",
"42512539": "ID: 42512539\nTitle: Cognitive Impairment Associated with Chemotherapy: Neuroimmunological Interactions, Gut-Brain Axis, and Therapeutic Approaches.\nAbstract: Chemotherapy is a treatment designed to contain or eradicate neoplastic cells; however, patients may experience various treatment-related adverse effects. Chemotherapy-related cognitive impairment (CRCI), clinically referred to as \"chemobrain,\" is a frequent complication with a duration ranging from months to years, affecting between 17% and 70% of cancer patients. These cognitive deficits not only impair social, educational, and occupational functioning but may also impact survival outcomes, possibly by interfering with medication adherence and health-related behaviors. Emerging evidence has converged on an integrative cascade in which chemotherapy-induced systemic inflammation, intestinal dysbiosis, blood-brain barrier disruption, microglial/astroglial activation, and impaired hippocampal neurogenesis act in sequence rather than as independent pathways. Underlying pathophysiological mechanisms include neuroinflammation, reduced neurogenesis, loss of dendritic spines, oxidative stress, hormonal changes, epigenetic modifications, and mitochondrial dysfunction. In contrast, repair mechanisms involve complex glial responses, particularly those of astrocytes and microglia. Emerging studies suggest a link between changes in the microbiome and cognitive decline, demonstrating the importance of bidirectional communication in the gut-brain axis. Current research seeks to determine appropriate tests to identify chemobrain. Therefore, several biomarkers, such as GFAP, S100\u03b2, and isoprostanes, have been proposed to assess chemobrain, alongside screening tools such as MoCA, MMSE, and CAB-CF, to evaluate cognitive impairment and enable early detection. Pharmacological candidates-including lithium, fluoxetine, methylphenidate, modafinil, metformin, agomelatine, and melatonin-as well as nutritional and lifestyle interventions such as physical exercise, omega-3 fatty acids, curcumin, probiotics, and traditional Chinese medicine formulations-have been investigated, predominantly in animal models. These remain candidate, not validated, therapies; clinical evidence in CRCI populations is limited, heterogeneous, or absent, and well-powered randomized controlled trials are required before any recommendation can be issued. However, optimal strategies for symptom improvement remain unclear, as various approaches have yielded mixed outcomes. This review provides a comprehensive overview of chemobrain, focusing on its molecular mechanisms, interactions with the gut-brain axis, and potential therapeutic targets to improve the quality of life for cancer survivors.",
"42512767": "ID: 42512767\nTitle: Rethinking Congestion in Heart Failure from Volume Overload to Venous Pressure and Organ Disfunction with VExUS.\nAbstract: Congestion is a major driver of symptoms, hospitalization, and adverse outcomes in heart failure (HF), yet its clinical assessment remains challenging. Traditional approaches based on physical examination, biomarkers, and isolated imaging surrogates often fail to capture the complexity of systemic venous congestion and its impact on organ function. In HF, congestion should be interpreted as a multifactorial process resulting from the interaction between intravascular volume burden, venous compliance, cardiac filling pressures, neurohormonal activation, blood volume redistribution, and organ-specific susceptibility. In this context, point-of-care ultrasound has emerged as a promising adjunctive tool for bedside congestion assessment. The Venous Excess Ultrasound (VExUS) score integrates inferior vena cava assessment with Doppler analysis of hepatic, portal, and intrarenal veins, allowing for the evaluation of venous pressure transmission and organ-level congestion. Observational studies suggest that VExUS and related venous Doppler abnormalities correlate with invasive hemodynamic parameters and are associated with acute kidney injury, diuretic response, heart failure hospitalization, and mortality. Serial changes in venous congestion may provide additional information regarding treatment response and clinical trajectory. However, the available evidence remains heterogeneous across acute HF, ambulatory HF, cardiorenal syndrome, and critical care populations, and randomized trials evaluating VExUS-guided management are lacking. Therefore, VExUS should be interpreted as a complementary tool within a multimodal assessment that includes echocardiography, lung ultrasound, biomarkers, renal function, urine output, physical examination, and response to therapy. By integrating fluid burden with venous pressure transmission and organ perfusion, multimodal ultrasound may support more individualized congestion assessment and risk stratification in HF.",
"42513192": "ID: 42513192\nTitle: Intestinal and Blood-Brain Barrier Dysfunction in Lupus: Emerging Mechanisms and Modulation by Cinnamon.\nAbstract: Systemic lupus erythematosus (SLE) is a complex autoimmune disease with evolving pathogenesis. Biological barriers, especially intestinal and blood-brain barriers (BBBs) with their tight junctions (TJ), are gaining attention in recent years as key players in disease initiation and progression. Among natural products targeting these barriers, cinnamon is emerging as a multi-targeted modulator of TJ. This narrative review integrates current evidence about gut and brain barrier dysfunction in lupus pathogenesis and highlights, on the basis of animal studies, the potential of cinnamon as a therapeutic candidate to restore barrier integrity and attenuate immune and neuroinflammation associated with lupus. Experimental evidence from lupus models supports the role of TJ disruption in disease pathogenesis. The alteration of TJ protein distribution in the epithelial barrier is correlated with an increased permeability of the intestinal barrier and changes in the microbiota composition in lupus, with consequent alteration in the gut-liver axis, liver inflammation and oxidative stress. Pre-clinical studies have demonstrated the restorative effect of cinnamon on gut TJ and permeability, microbiota and the gut-liver axis. Moreover, accumulating data suggest BBB disruption in lupus, correlated with neuroinflammation and behavioral disturbances. A murine model demonstrates the protective effect of cinnamon on BBB, especially via TJ localization, with the alleviation of neuropsychiatric alterations. Future perspectives should focus on cinnamon's effect on the gut-brain axis and translational studies.",

High humidity has been clinically associated with worsened joint symptoms, but the microbial and metabolic mechanisms remain unclear. We investigated whether a gut microbiota-metabolism axis contributes to humidity-associated aggravation of collagen-induced arthritis (CIA). Methods: CIA mice were maintained under normal or high relative humidity. We integrated 16S rRNA and metagenomic sequencing, liquid chromatography-tandem mass spectrometry metabolomics, and intestinal barrier assessments. Fecal microbiota transplantation (FMT) was performed to evaluate microbiota dependency. Based on multi-omics findings, we quantified chondroitin sulfate (CS) and conducted functional experiments involving Prevotella stercorea (P. stercorea) supplementation, CS administration, and in vitro degradation assays. Results: High humidity aggravated arthritis severity and systemic inflammation, including increased interleukin-6, interleukin-17A, and granulocyte colony-stimulating factor, and was accompanied by impaired intestinal barrier integrity. FMT supported a microbiota-dependent contribution. Metagenomic analysis identified enrichment of P. stercorea and glycosaminoglycan degradation pathways under high humidity. CS abundance was reduced in articular cartilage, P. stercorea degraded CS in vitro and was associated with cartilage CS loss in vivo, and CS supplementation attenuated arthritis under high humidity and reduced the arthritis-promoting effects associated with P. stercorea. Conclusions: High humidity is associated with microbiota-dependent functional remodeling, enhanced CS degradation, and aggravated arthritis in CIA mice. These findings suggest that humidity-associated alterations in microbial CS metabolism may link environmental exposure to cartilage disruption and joint inflammation.",
"42514135": "ID: 42514135\nTitle: Maternal Microbiome in Gestational Diabetes Mellitus: Mechanisms, Biomarkers, and Therapeutic Perspectives.\nAbstract: Gestational diabetes mellitus (GDM) is an increasingly prevalent metabolic disorder of pregnancy, driven by rising maternal age, obesity, and complex metabolic-inflammatory interactions. Emerging evidence implicates the maternal microbiome as a key modulator of metabolic adaptation during gestation; however, its precise role in GDM pathogenesis remains incompletely defined. This narrative review synthesizes current knowledge on microbiome alterations across gut, vaginal, and oral niches, focusing on their contribution to insulin resistance, metabolic endotoxemia, and immune dysregulation. GDM is consistently associated with reduced microbial diversity, depletion of beneficial taxa (e.g., Akkermansia, Bifidobacterium, Faecalibacterium), and expansion of pro-inflammatory pathobionts, which collectively may impair intestinal barrier integrity and promote low-grade systemic inflammation. These mechanisms are linked to altered insulin signaling and adverse maternal-fetal outcomes. In parallel, microbiome-derived metabolites and early taxonomic signatures have been proposed as potential biomarkers for first-trimester risk stratification, offering an opportunity to overcome the limitations of late diagnostic approaches such as the oral glucose tolerance test. Despite these advances, most available evidence remains associative, with substantial heterogeneity across studies and limited mechanistic validation. The clinical utility of microbiome-based interventions-including dietary modulation, prebiotics, and probiotics-remains promising but inconclusive, with outcomes highly dependent on individual, microbial, and methodological factors. Overall, the maternal microbiome represents a compelling but still evolving target in GDM research. Future progress will depend on standardized methodologies, longitudinal multi-omics studies, and the development of precision medicine approaches capable of integrating microbial, metabolic, and host data. Such advances may enable earlier diagnosis, targeted prevention, and ultimately the disruption of intergenerational metabolic risk.",
"42514364": "ID: 42514364\nTitle: NAD Metabolism in Acute Myeloid Leukaemia: Biological Rationale and Therapeutic Opportunities.\nAbstract: Acute myeloid leukaemia (AML) exhibits profound metabolic plasticity that enables leukaemic cells to survive environmental stress, nutrient limitation, and therapeutic pressure, ultimately driving disease persistence and relapse. While genetic and epigenetic alterations have guided risk stratification and therapeutic development, accumulating evidence indicates that nutrient-dependent metabolic rewiring represents a critical and targetable vulnerability in AML. Nicotinamide adenine dinucleotide (NAD) is a central metabolic cofactor whose intracellular availability is tightly linked to dietary intake of its precursors, including tryptophan, niacin (vitamin B3), nicotinamide, and nicotinamide riboside. NAD supports redox balance, mitochondrial metabolism, DNA repair, and stress adaptation, processes that are particularly critical for leukaemic stem cell survival under therapeutic stress. Recent studies demonstrate that AML cells, including those resistant to venetoclax- and hypomethylating agent-based regimens, exhibit heightened dependence on the NAD salvage pathway mediated by nicotinamide phosphoribosyltransferase (NAMPT). Pharmacological inhibition of this pathway induces profound NAD depletion, mitochondrial dysfunction, and selective leukaemic cell death. In this review, we integrate nutritional biology with emerging translational evidence to examine NAD metabolism as a nutrient-regulated metabolic vulnerability in AML. We discuss dietary sources and systemic regulation of NAD, the role of NAD-dependent pathways in leukaemic persistence, the translational exploitation of NAD salvage dependency, and the emerging controversy surrounding NAD supplementation in cancer. Finally, we highlight key knowledge gaps and future directions at the interface of nutrition, metabolism, and therapy response in AML.",
"42514440": "ID: 42514440\nTitle: The Effect of a Low-FODMAP Diet on Quality of Life, Severity of Symptoms and Leaky Gut in Patients with Irritable Bowel Syndrome.\nAbstract: Objective: We aimed to investigate the effects of a low-FODMAP (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) diet on symptom severity, quality of life, and fecal zonulin levels in patients with irritable bowel syndrome (IBS). Methods: Twenty-four patients with IBS were prospectively randomized to either a low-FODMAP diet (LFD) or a traditional diet (TD) for 4 weeks. IBS Symptom Severity Scale (IBS-SSS), IBS Quality of Life (IBS-QOL), and fecal zonulin levels were assessed at baseline and week 4 in both groups. In the LFD group, FODMAP-containing foods were gradually reintroduced after week 4, and all assessments were repeated at week 16. Changes in laboratory parameters, fecal zonulin levels, IBS-SSS, and IBS-QOL scores were evaluated. Results: Fecal zonulin levels did not differ significantly between groups at baseline or week 4, and no significant within-group changes were observed over time (all p > 0.05). IBS-SSS scores improved significantly at week 4 in both groups compared with the baseline (p < 0.05), with no significant difference in the magnitude of improvement between groups (p > 0.05). In the LFD group, IBS-SSS scores increased at week 16 compared with week 4 (p < 0.05). Similarly, IBS-QOL scores improved significantly at week 4 in both groups (p < 0.05), without significant between-group differences (p > 0.05). In the LFD group, IBS-QOL scores returned to baseline levels by week 16. Conclusions: Both the LFD and TD were associated with significant short-term improvements in IBS symptom severity and quality of life. However, the LFD did not demonstrate superiority over the TD. Furthermore, no statistically significant changes in fecal zonulin levels were observed in either group, although these findings should be interpreted cautiously. In the LFD group, some improvements observed at week 4 were attenuated following FODMAP reintroduction at week 16; however, these findings represent exploratory within-group observations and should not be interpreted as evidence of long-term treatment efficacy or sustained benefit following FODMAP reintroduction.",
"42514886": "ID: 42514886\nTitle: Anti-Inflammatory Effects of Ginsenoside Rg1 and Low-Dose Ginseng Extract in an Astrocyte-Microglia Co-Culture Model of Inflammation.\nAbstract: Background: Neuroinflammation contributes to the etiopathology and symptom severity of neurodegenerative and neuropsychiatric disorders. Glial cells, especially microglia and astrocytes, play a crucial role in neuroinflammation. It has been reported that ginseng (Panax ginseng) and its bioactive component ginsenoside Rg1 exhibit anti-inflammatory effects and can improve cognitive performance in various models. However, the exact underlying mechanisms remain unclear. Methods: Astrocyte-microglia co-culture models simulating physiological (M5, 5-10% microglia) and pathological/inflammatory (M30, 30-40% microglia) conditions were treated with different concentrations of ginsenoside Rg1 (15, 30, 45 \u00b5M) or ginseng extract (derived from Korean red ginseng) at low (12.5, 25, 37.5 \u00b5g/mL) or high doses (125, 250, 375 \u00b5g/mL) for 24 h. Cell viability was assessed using the MTT assay while microglial reactivity was examined using immunocytochemistry. Astrocytic gap-junctional coupling was investigated using the scrape-loading method, and connexin 43 (Cx43) expression was analyzed using immunocytochemistry and Western blot. Results: Both Rg1 and low-dose ginseng extract reduced microglial activation under inflammatory conditions by promoting a shift in microglia from an activated to homeostatic (resting) phenotype. Rg1 preserved astrocytic gap-junctional function by preventing the inflammation-induced downregulation of Cx43 expression and enhancing Cx43-mediated gap-junctional intercellular communication. Rg1 caused a significant reduction in glial cell viability, but only at high concentrations (30 and 45 \u00b5M), under inflammatory conditions. High-dose ginseng extract showed a significant concentration-dependent reduction in glial cell viability under physiological and pathological conditions, without comparable anti-inflammatory benefits. Conclusions: This study demonstrates that low-dose ginseng and its active compound Rg1 exert anti-inflammatory effects by modulating astrocytic coupling and microglial reactivity. These results provide a novel therapeutic perspective for the use of ginseng in the treatment of neurodegenerative and neuropsychiatric diseases related to neuroinflammation.",

The human gut microbiota, comprising over 3000 bacterial species, regulates immune responses, hormonal signals, and metabolite production, maintaining homeostasis under normal conditions. Dysbiosis, or microbial imbalance, has been linked to various central nervous system (CNS) disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and autism spectrum disorder (ASD). Given the growing interest in this topic and the limited effectiveness of current therapeutic strategies for managing patients with AD, the purpose of the current narrative review is to analyze the pathophysiological role of the GMBA in the pathogenesis of AD and assess potential therapeutic strategies targeting the GMBA, particularly the microbiome and its metabolites. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science to identify clinical studies, experimental research, and review articles examining the GMBA in health and AD, as well as related therapeutic strategies. The search terms included \"Alzheimer's disease\", \"neuroinflammation\", \"amyloid-beta\", \"tau\", \"gut-brain axis\", \"microbiome\", \"short-chain fatty acids\", \"probiotics\", \"prebiotics\", and \"fecal microbiota transplantation\". In AD, altered gut microbiota composition is associated with neuroinflammation, neurodegeneration, and exacerbation of disease progression. Probiotics have shown potential in enhancing cognitive function and reducing neuroinflammation by modulating microbiota composition and influencing brain-derived neurotrophic factor (BDNF) levels. Prebiotics, through their impact on gut microbiota and metabolite production, also offer therapeutic promise by improving cognitive function and mitigating neuroinflammation. With its historical and modern applications, fecal microbiota transplantation (FMT) may represent a potential strategy for addressing dysbiosis and its neurological implications. This manuscript focuses on GMBA and its effects on neuroinflammation, neurodegeneration, and CNS health while emphasizing the need for further research into microbiome-based therapies and the gut-brain relationship in patients with AD.",

Although dengue virus (DENV) non-structural protein 3 (NS3) undergoes nuclear trafficking, the role of nuclear export pathways in its localization and in viral replication remains poorly understood. Here, we show that pharmacological inhibition of exportin 1 (XPO1) promotes the accumulation of DENV-2 NS3 in both the nucleus and mitochondria of infected Huh-7 cells. XPO1 inhibition also induces mitochondrial morphological alterations resembling those observed during DENV infection. Moreover, blockade of nuclear export enhances DENV-2 replication in interferon-stimulated cells by reducing type I interferon production, suggesting the establishment of a pro-viral cellular environment. Our findings reveal that XPO1-mediated nuclear export contributes to the regulation of NS3 localization and links nuclear export to mitochondrial remodeling and suppression of antiviral signaling during DENV infection.",

The effect of fullerenol C\u2086\u2080(OH)\u2083\u2086 on the structural-dynamic and functional parameters of mitochondria, both isolated in vitro and in vivo in Wistar rats, was studied. It was found that fullerenol at a dose of 10\u00a0mg/kg reduced bioenergetic parameters of both glutamate-dependent and succinate-dependent intracellular respiration in vivo. In the in vitro model system, fullerenol at a dose of 0.2\u00a0mg/ml significantly decreased the oxygen consumption rates in all metabolic states, leading to a reduction in the Lardy and Chance respiratory control ratios and the P/O ratio. Conversely, at a dose of 0.1\u00a0\u00b5g/ml, fullerenols significantly increased these respiratory parameters. Fullerenols, both in vivo and in vitro, increased the viscosity of annular and total mitochondrial membrane lipids. They did not affect the polarity of total lipids but decreased the polarity of annular lipids. Fullerenols at high doses induced significant conformational changes in membrane proteins, increasing their immersion into the lipid matrix. Our results demonstrate that fullerenols modulate mitochondrial bioenergetics and membrane structural dynamics in a dose-dependent manner, which may have implications for understanding both the cytoprotective and potentially cytotoxic effects of these nanoparticles.",

This review synthesizes current evidence on the complementary, additive, and potentially synergistic interactions between probiotics and plant-derived phytochemicals within the MGBA. While the individual benefits of these dietary components are well established, their combined synbiotic application offers expanded mechanistic breadth through coordinated modulation of microbial ecology, epithelial barrier integrity, immune inflammatory signaling, and neurochemical pathways. Probiotics and phytochemicals interact bidirectionally via microbial biotransformation, enhancing short-chain fatty acid production, reducing endotoxin translocation, and attenuating systemic and neuroinflammation. These effects are further linked to indirect modulation of neurotransmitter systems and neurotrophic signaling relevant to mood regulation, cognitive function, and neurodegenerative processes. Evidence from preclinical and emerging clinical studies supports the relevance of these mechanisms in conditions such as Alzheimer's disease, Parkinson's disease, mood disorders, and Autism Spectrum Disorder, although human data remain limited. Overall, this narrative review proposes a mechanistic framework describing how probiotics and plant-derived phytochemicals may interact through complementary microbial, immune, and neurochemical pathways within the Microbiota-Gut-Brain Axis. It also highlights current knowledge gaps and emphasizes the need for well-designed clinical studies to validate their combined therapeutic potential.",

Metagenomic analysis revealed distinct microbial community structures, with increased abundance of Akkermansia massiliensis, Alistipes onderdonkii, and Barnesiella intestinihominis in AD. Phageome analysis revealed increased richness and altered composition, with more Podoviridae and fewer Microviridae. Functional profiling identified shifts in microbial metabolic pathways involving tryptophan and short-chain fatty acid metabolism. Untargeted metabolomics revealed elevated fecal spermidine, taurocholate, and glycerophosphocholine levels in patients with AD. A random forest model combining metabolites, gut metabolic modules, and bacteriophages achieved good within-cohort classification (AUC = 0.83) but lacked external validation due to unavailable matched fecal metabolomic data. Overall, these findings link AD to coordinated disruptions across bacterial, viral, and metabolic gut layers, highlighting the need for external validation and mechanistic studies.",

While surgical intervention is often lifesaving in severe NEC, the postoperative period introduces distinct challenges that critically influence survival and long-term outcomes. This review examines postoperative hyperinflammation as a central driver of morbidity following surgical NEC. Despite resection of necrotic bowel, many infants experience persistent systemic inflammation characterized by dysregulated innate immune activation, excessive cytokine release and sustained gut barrier dysfunction. Key mediators including tumor necrosis factor-alpha (TNF-\u03b1), interleukin (IL)-6, IL-1\u03b2 and IL-8 contribute to endothelial injury, capillary leak, hemodynamic instability and multiorgan dysfunction. Ongoing intestinal permeability and microbial translocation perpetuate inflammatory signaling, delaying mucosal healing and predisposing infants to recurrent NEC, sepsis and short bowel syndrome. Clinically, postoperative hyperinflammation manifests as systemic inflammatory response syndrome, coagulopathy, feeding intolerance, impaired wound healing and neurodevelopmental injury. Recovery is frequently prolonged by nutritional compromise, dependence on parenteral nutrition and recurrent infections, which further amplify inflammatory stress. Current management remains largely supportive, focusing on optimization of nutrition, infection prevention and multidisciplinary care. Emerging immunomodulatory and microbiome-based therapies remain investigational. Postoperative hyperinflammation remains a difficult and complex sequelae of NEC and future investigation is needed to improve long-term outcomes.",

Emerging evidence suggests that the gut microbiota influences mood disorders and psychotropic drug response, raising the hypothesis that specific microbial signatures may modulate lithium responsiveness. In this study, we characterized taxonomic and functional gut microbiota profiles in 77 patients with bipolar disorder, of whom 40 were receiving lithium (20 responders, 20 non-responders) and 37 were treated with valproate as the main mood stabilizer (valproate, n = 31; lamotrigine, n = 6), with the aim of identifying potential microbial markers of clinical response. Microbiota composition was assessed through 16S rRNA sequencing targeting the V3-V4 region. Differential abundance was evaluated using Analysis of Composition of Microbiomes with Bias Correction (ANCOM-BC2), and the functional potential was inferred using the Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2 (PICRUSt2). Our finding showed that lithium treatment was associated with a selective gut microbiota reorganization, including reduced Actinobacteria (Actinomycetota) phylum, notably Coriobacteriia class, and enrichment in Firmicutes (Bacillota) taxa, including Selenomonadales, Megamonas and Clostridia taxa, alongside reductions in primary fermentative and biosynthetic pathways. This shift, characterized by a reduction of primary fermenters and enrichment of secondary fermenters and SCFA-producing taxa, suggests a more efficient fermentative ecosystem in lithium-treated patients. Responders showed enrichment in methanogenic taxa (Methanobrevibacter) and Clostridiales vadinBB60 group when compared with patients treated with other mood stabilizers; however, these differences were not observed in the direct comparison between lithium responders and non-responders. While causal relationships cannot be inferred, these findings indicate treatment-associated microbial patterns and support further investigation into microbiota-directed adjunctive therapies.",

Growing evidence suggests that antibiotics-induced gut microbiota dysbiosis may contribute to neuropsychiatric conditions, including anxiety. However, the mechanistic pathways linking chronic antibiotic exposure, microbial disruption, and anxiety-like behaviors remain largely unclear. To investigate the effects of antibiotic exposure on gut-brain axis function, mice were administered antibiotic-containing drinking water for either short-term or long-term durations. Behavioral assessments, 16S rRNA gene sequencing, biochemical analyses, histological staining, and Western blotting were used to evaluate anxiety-like behaviors, microbiota composition, tryptophan (Trp) metabolism, intestinal barrier integrity, and inflammation in both the colon and hippocampus. Long-term, but not short-term, antibiotic treatment induced pronounced anxiety-like behaviors in mice. Microbiota analysis revealed that long-term antibiotic exposure significantly reduced microbial diversity and altered the abundance of key bacterial genera. These changes were associated with disrupted colonic Trp metabolism, reflected by decreased Trp and 5-HT levels in the colon and serum, along with suppressed expression of the Trp metabolic enzyme TPH1 and 5-HT4R. Additionally, long-term antibiotic treatment impaired intestinal barrier integrity, downregulated tight junction proteins and MUC2, and activated colonic TLR4/NF-\u03baB/NLRP3 inflammatory signaling pathways. Neuroinflammation was also observed in the hippocampus. Our results reveal a time-dependent effect of antibiotic-induced anxiety-like behaviors and suggest that gut microbiota dysbiosis, disrupted colonic Trp metabolism, intestinal barrier dysfunction, and neuroinflammation may collectively contribute to the behavioral alterations associated with long-term antibiotic exposure. These findings provide new insights into the gut-brain mechanisms underlying microbiota-associated mood disorders.",
"42521674": "ID: 42521674\nTitle: Mitochondrial quality control in health and disease: mechanisms and therapeutic targets.\nAbstract: Mitochondria are essential for cellular homeostasis, integrating various signals to control key cellular functions such as metabolism, apoptosis, inflammation, cell proliferation and redox balance. Given their multifaceted functions, it is not surprising that mitochondrial dysfunction has been implicated as a key contributor to the pathogenesis of numerous human diseases. Consequently, preserving mitochondrial integrity and functionality is vital for overall organismal health. Mitochondrial health is safeguarded by a sophisticated and tightly regulated network of quality control systems. These include mitochondrial proteostasis, which ensures proper protein folding and degradation; mitochondrial biogenesis, which governs the synthesis of new mitochondria; mitochondrial dynamics, encompassing fusion and fission processes; and mitophagy, the selective autophagic removal of damaged mitochondria. Additionally, these core systems are intricately connected to other crucial mitochondrial processes, such as the maintenance of mitochondrial DNA integrity, the regulation of cristae architecture, and the control of mitochondrial permeability transition, all of which are indispensable for optimal mitochondrial performance. Preclinical and clinical studies consistently demonstrate a strong link between impairments in these quality control mechanisms and both aging and the development of a wide spectrum of diseases. These include cancer, metabolic disorders, cardiovascular conditions, neurodegenerative diseases and autoimmune pathologies. In this review, we explore the different facets of mitochondrial quality control and discuss their implications in disease progression and aging. Furthermore, we highlight recent advances in interventions and therapies aimed at modulating mitochondrial quality control, providing an overview of their potential to mitigate disease burden and promote healthy aging.",

Neuroinflammation occurs throughout various stages of these diseases with expanding complexity. Currently, no effective therapies exist that specifically target neuroinflammatory processes in these disorders. In this review, we synthesize current understanding of central and peripheral inflammatory mechanisms implicated in both diseases. We illustrate how endogenous pathological triggers, such as amyloid-\u03b2 (A\u03b2) peptide, hyperphosphorylated tau, and \u03b1-synuclein, activate glial cells, contributing to chronic neuroinflammation that exacerbates neurodegeneration. Additionally, peripheral factors, including systemic inflammation, environmental exposures, and gut-brain axis interactions, are discussed for their roles in modulating neuroinflammatory responses. Notably, the underappreciated roles of oligodendrocyte precursor cells and oligodendrocytes in neuroimmune crosstalk are also highlighted. Advanced methodologies, including glial cell imaging, single-cell transcriptomics, and human induced pluripotent stem cell-derived organoid models, are providing unprecedented insights into the molecular and cellular mechanisms underlying neuroinflammation. Finally, we evaluate emerging therapeutic strategies and ongoing clinical trials targeting neuroinflammatory pathways and analyze the potential of immunomodulatory approaches to slow disease progression. This comprehensive review emphasizes that precise targeting of neuroinflammation represents a tractable strategy for developing effective disease\u2011modifying treatments for AD and PD.",
"42522403": "ID: 42522403\nTitle: Minoxidil Sulfate Regulates JAK/STAT Signalling and Mitochondrial Function in Alopecia Areata.\nAbstract: Alopecia areata (AA) is an autoimmune hair disorder characterized by interferon-gamma (IFN-\u03b3)-driven inflammation and collapse of hair follicle immune privilege. Although Janus kinase (JAK) inhibitors are effective, incomplete or delayed responses remain common. Minoxidil is frequently combined with JAK inhibitors in clinical practice, yet its immunomodulatory mechanisms in AA are unclear. We investigated the effects of minoxidil sulfate (MXS) on inflammatory signalling, immune privilege-associated features and mitochondrial stress responses, and evaluated whether MXS enhances the anti-inflammatory effects of the JAK inhibitor baricitinib. Clinical observations of patients receiving combination therapy were descriptively assessed. Mechanistic studies were conducted in human outer root sheath (ORS) cells stimulated with IFN-\u03b3 and polyinosinic:polycytidylic acid to model the AA inflammatory microenvironment. Representative clinical observations suggested accelerated hair regrowth after addition of oral minoxidil to baricitinib. In inflamed ORS cells, MXS enhanced baricitinib-mediated suppression of STAT1 phosphorylation and IFN-\u03b3-inducible chemokines (CXCL9, CXCL10, CXCL11). MXS also exerted baricitinib-independent anti-inflammatory effects by inhibiting STAT1 and STAT3 activation. Furthermore, MXS reduced inflammatory induction of MHC class I expression and partially restored insulin-like growth factor-1 expression. MXS attenuated cytosolic and mitochondrial reactive oxygen species accumulation, mitochondrial DNA damage and loss of mitochondrial membrane potential, accompanied by suppression of NOX1 and NOX4 expression. These findings suggest that MXS modulates inflammatory signalling, preserves immune privilege-associated features and protects mitochondrial integrity, providing a mechanistic rationale for adjunctive use with JAK inhibitors without additional systemic immunosuppression.",

Although toxicological research has mainly focused on the gastrointestinal tract, increasing evidence suggests that the highly vascularized bone marrow may also be a relevant site for MNP accumulation. This narrative review proposes a \"gut-immune-bone\" axis linking intestinal barrier disruption, systemic translocation, and potential deposition within the bone marrow niche. Current experimental evidence, together with limited human detection data, suggests that MNPs may disturb osteoimmunological homeostasis by impairing osteogenesis and promoting macrophage-associated osteoclastogenesis, thereby favoring bone remodeling imbalance. We summarize potential mechanisms, including oxidative stress, nuclear factor-\u03baB (NF-\u03baB) signaling, NOD-like receptor protein 3 (NLRP3) inflammasome activation, gut microbiota dysbiosis, endocrine disruption, and MNP-heavy metal co-exposure. We also discuss susceptible pediatric and geriatric populations and highlight the need to incorporate osteoimmunological endpoints into future MNP risk assessment.",
"42523904": "ID: 42523904\nTitle: Gut feelings and sweet teeth: nutritional solutions to the gut damage in inflammatory bowel disease and HIV infection.\nAbstract: Damage to the mucosal layer of the gut is a central feature of chronic inflammatory diseases, often resulting in gut dysbiosis, microbial imbalances, and dysregulated immunometabolism. Gut dysfunction significantly impacts human health, disrupting metabolic, cardiovascular, and neurological systems, and leading to metabolic syndrome. Here, we discuss two clinical entities that are apparently unrelated but actually share similar alterations to gut mucosal barrier integrity: inflammatory bowel disease (IBD) and human immunodeficiency virus (HIV). We use the particular cases of pediatric IBD and nonhuman primate models of HIV infection to compare and contrast the impact of these diseases on gut integrity and microbiome composition. We also explore potential therapies, focusing on dietary interventions. Both HIV infection and IBD cause gut barrier disruption, but via different mechanisms. HIV rapidly depletes mucosal CD4+ T cells (especially Th17 cells), weakening epithelial defenses, leading to a loss of tight junctions (\"leaky gut\"), microbial translocation, and systemic inflammation. In IBD (Crohn's disease and ulcerative colitis), chronic immune attacks on the gut lining produce ulcers and tight-junction defects. These ulcerations trigger immune-cell infiltration and markedly increase permeability. In both conditions, impaired mucus and epithelial integrity result in higher circulating lipopolysaccharides (LPS), macrophage activation, and systemic inflammation. HIV and IBD also induce distinct yet overlapping dysbioses. HIV infection is associated with markedly reduced bacterial diversity and an overgrowth of potentially inflammatory taxa (e.g., Proteobacteria, Prevotella). Similarly, IBD patients have low diversity and loss of beneficial Firmicutes (notably Faecalibacterium prausnitzii) with relative Proteobacteria overabundance. In both diseases, the gut flora shifts away from fiber-fermenting commensals to \"pathobionts,\" fueling local inflammation. While the therapeutic potential of targeting metabolic products is widely explored, there is also a push towards discovering nondrug solutions, particularly through diet and nutrition. We present the effects of micronutrient intake, feeding mechanisms (exclusive enteral nutrition), and different diets (high fiber, Mediterranean, high fat) on disease progression and cellular metabolism. As a low-intervention approach, nutrition has enormous potential to improve human health by reducing inflammation and associated metabolic disturbances. Finally, we emphasize the capabilities of using animal models to elucidate the complexities of disease mechanics in IBD and HIV.",
"42524083": "ID: 42524083\nTitle: Pulmonary injury in inflammatory bowel disease: intestinal barrier disruption, gut-lung axis remodeling, and treatment-related lung toxicity.\nAbstract: Inflammatory bowel disease (IBD)-associated pulmonary injury is one of the frequently underestimated extraintestinal manifestations in clinical practice. It can present as subclinical pulmonary function abnormalities, radiographic changes, or overt inflammatory pulmonary diseases and often overlaps with infection- and treatment-related pulmonary toxicity, complicating early recognition and differential diagnosis. Growing evidence indicates that IBD-associated pulmonary injury is not an isolated pulmonary event but rather a cross-organ pathological process jointly driven by disruption of the intestinal mucosal barrier, dysbiosis, and aberrant microbial metabolites, systemic inflammation, and abnormal immune cell trafficking. This article provides a comprehensive review of current basic and clinical research evidence regarding intestinal barrier dysfunction, bidirectional gut-lung axis regulation, immune remodeling mediated by microbial metabolites, such as short-chain fatty acids (SCFAs), and the mechanisms and differential diagnosis of drug-induced pulmonary injury in IBD treatment. Existing studies suggest that SCFAs, tryptophan metabolites, immune cell homing, and alterations in the local pulmonary microbiota may represent key regulatory nodes in IBD-associated pulmonary injury; however, prospective studies integrating intestinal inflammatory activity, circulating biomarkers, pulmonary phenotypes, and drug exposure are still lacking. In the future, emphasis should be placed on establishing a stratified diagnostic framework for distinguishing pulmonary involvement intrinsic to the disease, infection, and drug-induced pulmonary injury, and on evaluating precision intervention strategies targeting microbial function, metabolite supplementation, and barrier repair to advance the translational application of mechanistic research on IBD-associated pulmonary injury into clinical practice.",

While probiotics and prebiotics have been widely studied for their psychobiotic effects, postbiotics-metabolic byproducts of probiotics-represent an underexplored area with potential therapeutic applications. Understanding the role of postbiotics in mental health disorders, such as depression, psychosis, and mania, could lead to novel treatment strategies. This review examines the psychobiotic potential of postbiotics and their mechanisms of action. A systematic literature review was conducted to evaluate the effects of postbiotics on mental health conditions. We searched PubMed, Medline, EMBASE, and the Cochrane Library for English-language articles published between January 1, 2015, and January 1, 2025, using keywords such as \"postbiotic,\" \"paraprobiotic,\" \"depression,\" \"anxiety,\" and \"psychosis.\" A manual search supplemented the electronic search to ensure comprehensive coverage. Studies focusing on postbiotic effects on mood regulation, neuroinflammation, and neurotransmitter modulation were included. Postbiotics demonstrate promising psychobiotic effects in depression, psychosis, and mania. They modulate neurotransmitter levels, including serotonin and gamma-aminobutyric acid (GABA), and reduce neuroinflammation, contributing to improved mood and cognitive function. Additionally, postbiotics influence the hypothalamic-pituitary-adrenal (HPA) axis, enhancing stress response and emotional regulation. These findings suggest that postbiotics may serve as effective therapeutic agents for mental health disorders. Postbiotics offer significant potential as novel interventions for mental health conditions, with mechanisms involving neurotransmitter modulation and neuroinflammation reduction. Further empirical research is needed to elucidate their clinical applications and optimize therapeutic protocols. This review highlights the importance of postbiotics in advancing innovative strategies to improve mental health outcomes and well-being.",

The transcription factor SOX9 has been linked to AD progression, but its mechanism remains unclear. SOX9 expression was measured in peripheral blood mononuclear cells from 24 patients with AD and 24 age-matched healthy controls and correlated with Montreal Cognitive Assessment scores. An A\u03b21-42-stimulated BV-2 cell model was used to investigate the effects of SOX9 and apoptosis signal-regulating kinase 1 (ASK1) on microglial polarization. Neuronal injury was evaluated in a BV-2/SH-SY5Y co-culture system. The transcriptional regulation of ASK1 by SOX9 was examined using dual-luciferase reporter and chromatin immunoprecipitation assays. ASK1 overexpression and the ASK1 inhibitor GS-4997 were used for mechanistic validation. SOX9 expression was increased in peripheral blood mononuclear cells from patients with AD and was negatively correlated with cognitive function. SOX9 was also upregulated in A\u03b21-42-stimulated BV-2 cells. SOX9 overexpression enhanced M1-associated inflammatory markers and reduced M2-associated markers, whereas SOX9 knockdown produced the opposite effects. In the co-culture system, SOX9 knockdown increased SH-SY5Y cell viability, reduced LDH release and apoptosis, increased Bcl-2 expression, and decreased Bax and cleaved caspase-3 expression. SOX9 bound to the ASK1 promoter and promoted ASK1 transcription. SOX9 silencing suppressed ASK1, JNK, and p38 phosphorylation, while ASK1 overexpression reversed the effects of SOX9 knockdown on microglial polarization and neuronal injury. Consistently, GS-4997 blocked the pro-inflammatory and neurotoxic effects induced by SOX9 overexpression. SOX9 exacerbates AD neuroinflammation by promoting microglial M1 polarization via the ASK1/JNK signaling axis.",

This study investigated the neuroprotective effects and epigenetic mechanisms of EA in a mouse model of ischemic stroke. Cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in mice. EA was applied at Baihui (GV20) and left Zusanli (ST36) acupoints following surgery. Neurological deficits were assessed, infarct volume was measured by TTC staining, and neuronal damage was evaluated by Nissl staining. RhoGDI\u03b1 protein expression was determined by Western blot. Global DNA methylation was quantified by ELISA, and promoter-specific methylation of RhoGDI\u03b1 was examined by quantitative methylation-specific PCR (MSP), and mRNA expression of candidate DNA methyltransferases (DNMTs) and demethylases (TETs) was measured by qPCR. EA alleviated MCAO-induced brain injury, as reflected by improved neurological scores, reduced infarct volume, and attenuated neuronal loss. RhoGDI\u03b1 expression was downregulated after MCAO and restored by EA treatment. Pharmacological inhibition of RhoGDI\u03b1 abolished the neuroprotective effects of EA, underscoring its essential role in EA-mediated protection. Mechanistically, MCAO induced hypermethylation of the RhoGDI\u03b1 promoter, which was reversed by EA, leading to restoration of RhoGDI\u03b1 expression. Furthermore, co-administration of the DNA methylation inhibitor 5-Azacytidine synergistically enhanced the neuroprotective efficacy of EA. Our findings demonstrate that EA ameliorates ischemic brain injury in association with epigenetic regulation of RhoGDI\u03b1 via promoter demethylation. This study identifies RhoGDI\u03b1 as a key mediator of EA-induced neuroprotection and suggests that the DNA methylation-RhoGDI\u03b1 axis may represent a promising therapeutic target for ischemic stroke.",
"42526548": "ID: 42526548\nTitle: Forsythiae Fructus attenuates DSS-induced colitis and associated neuroinflammation with modulation of AMPK/mTOR-related autophagy signaling.\nAbstract: Forsythiae Fructus, the dried fruit of Forsythia suspensa (Thunb.) Vahl is a traditional herbal medicine widely used in East Asia for inflammatory disorders. Although Forsythiae Fructus exhibits anti-inflammatory activity in experimental colitis, its effects on colitis-associated brain inflammation and autophagy-related signaling remain unclear. This study investigated the protective effects of Forsythiae Fructus extract (FF) on intestinal and brain inflammatory responses in dextran sulfate sodium (DSS)-induced colitis mice and explored the involvement of AMPK/mTOR-related signaling. Mice received FF (100\u202fmg/kg) or 5-aminosalicylic acid (ASA, 100\u202fmg/kg) by oral gavage once daily for 15 days. DSS (5%, w/v) was administered in drinking water from day 7 to day 12, followed by a 3-day recovery period with normal drinking water (day 12-15). Disease severity, intestinal permeability, inflammatory mediators, and autophagy-related markers in the colon and brain were assessed using endoscopy, histology, ELISA, immunoblotting, immunofluorescence, and RT-qPCR. FF substantially alleviated DSS-induced colitis by attenuating body weight loss (-9.0% vs. -17.1% in DSS), reducing the disease activity index by approximately 40%, increasing colon length by 18%, and decreasing intestinal permeability by approximately 59%. FF restored epithelial barrier integrity by increasing Occludin, ZO-1, Muc2, and Tff3 expression. It also decreased IL-1\u03b2, IL-6, and TNF-\u03b1 levels in the colon, serum, and brain, accompanied by reduced microglial activation and NF-\u03baB signaling. FF increased AMPK phosphorylation and LC3B-II/LC3B-I ratios while reducing mTOR activation and SQSTM1 accumulation in both colon and brain tissues. FF effectively alleviated DSS-induced colitis, reducing disease activity by approximately 40% and restoring intestinal barrier function. These protective effects were accompanied by suppression of intestinal and brain inflammatory responses and modulation of AMPK/mTOR-related autophagy signaling. These findings provide experimental support for the traditional use of FF in inflammatory disorders and highlight its potential as a protective candidate for ulcerative colitis and its associated gut-brain inflammatory manifestations.",
"42526737": "ID: 42526737\nTitle: Cannabinoid receptor-mediated modulation of the gut-brain axis under chronic stress: Neuroinflammatory mechanisms, microbial metabolites, and sexual dimorphism.\nAbstract: Chronic stress disrupts the gut-brain axis (GBA) through coordinated dysfunction of the intestinal barrier and of the vascular interfaces that protect the brain, fostering a neuroinflammatory state implicated in mood disorders, neuropsychiatric conditions, and chronic pain. This narrative review synthesizes evidence across five domains. First, the inflammatory cascade by which stress-induced disruption of the epithelial and gut vascular barriers activates the NLRP3 inflammasome and sustains central neuroinflammation. Second, microbial metabolites, namely short-chain fatty acids (SCFAs), tryptophan-kynurenine products, and indole derivatives, as modulators of gut-brain homeostasis. Third, the gut microbiome-endocannabinoidome axis, including the capacity of commensal bacteria to generate endocannabinoid-like N-acyl amides that engage host receptors. Fourth, the receptor-specific pharmacology of phytocannabinoids, distinguishing \u03949-tetrahydrocannabinol (THC), which acts principally at CB1 and CB2 with comparable affinity, from cannabidiol (CBD), which has low affinity for these receptors and signals mainly through TRPV1, TRPA1, GPR55, PPARs, and 5-HT1A. Fifth, sexual dimorphism in barrier vulnerability and treatment response. In rodent models, chronic stress reduces intestinal and blood-brain barrier tight junction expression, elevates circulating lipopolysaccharide, and activates the NLRP3 inflammasome, while tryptophan metabolism shifts toward neurotoxic kynurenine products. Cannabinoid modulation of the kynurenine pathway and cannabinoid-mediated restoration of blood-brain barrier integrity remain mechanistic hypotheses extrapolated from indirect evidence rather than demonstrated mechanisms in chronic psychological stress paradigms. Human data are largely limited to small trials of microbiota-targeted interventions and of CBD in anxiety, and to observational endocannabinoidome-microbiome studies. These observations provide a preclinical rationale for GBA-targeted pharmacological strategies, with translational claims explicitly separated from mechanistic plausibility.",

However, their clinical translation is constrained by high molecular weight, poor solubility, low oral bioavailability, inefficient membrane permeability, nonspecific biodistribution, off-target degradation, and the concentration-dependent 'hook effect.' Exosomes, nanoscale extracellular vesicles with innate biocompatibility, low immunogenicity, prolonged circulation, and the ability to cross barriers such as the blood-brain barrier, offer a biologically integrated platform to overcome these limitations. This review traces the evolution of PROTAC technology, delineates the challenges of conventional delivery, and evaluates the rationale for exosomal encapsulation, including cargo protection, intracellular trafficking, endosomal escape, and release kinetics. We examine natural and engineered exosomes spanning source selection, active loading strategies, and surface functionalization for tissue-specific homing and synthesize therapeutic applications across viral infections, cancer, neurodegenerative disorders, and inflammatory diseases. Proof-of-concept studies, such as camel milk-derived exosomes delivering the BRD4-targeting PROTAC ARV-825, demonstrate enhanced permeability, lower IC50 values, and improved oral bioavailability. Finally, we discuss key hurdles to clinical translation: scalable production, purification, and standardization, and outline future directions for exosome-mediated targeted protein degradation.",

This review advances an effector-centered framework to explain how A. muciniphila acts through host-facing molecules, including outer membrane and secreted proteins such as Amuc_1100 (pilus-associated signaling, PAS) and P9, extracellular vesicles (EVs) and outer membrane vesicles (OMVs), and shed cell-envelope fragments and lipids. We synthesize evidence spanning barrier biology, immunometabolic regulation, infection and inflammatory injury, cancer immunology, and microbiota-gut-brain axis research. Across models, effectors modulate the mucus and epithelial barrier to limit translocation and dampen Toll-like receptor (TLR) signaling, but mucus-active enzymes or antigenic epitopes may also create liabilities in susceptible hosts. Defined effectors can reproduce key whole-cell effects: in high-fat diet (HFD)/carbon tetrachloride (CCl4) liver injury, vesicle preparations matched or exceeded pasteurized bacteria; Amuc_1100 maps to immune reprogramming and barrier signaling; and P9 links microbial cues to glucagon-like peptide 1 (GLP-1) release. Key gaps include physiological dose realism, equivalence across colony-forming units (CFU) and protein or vesicle doses, strain and culture-condition dependence of effector expression, and limited human data for brain-relevant endpoints. Effector-defined preparations and engineered delivery systems may improve standardization and safety, but translation will require rigorous characterization, dose-response validation, and mechanism-linked biomarkers.",

Introducing a polar, charged functional group at the end of the linker significantly increased the PROTAC's solubility. However, this polar group also significantly impaired the Brd4 degradation-inducing activity of these PROTACs, even though the PROTACs were designed not to disrupt the ternary complex formation among the POI, the E3 ligase, and the PROTAC. Capping the polar functional group restored the activity. These findings will be useful for designing functional PROTACs and PROTAC-based probes and will also help elucidate the modes of action of PROTACs.",

Accumulating preclinical evidence confirms the microbiota-gut-brain axis (MGBA) as a core regulatory hub in DCI pathogenesis, with gut microbiota dysbiosis being the initiating factor that disrupts host neuroendocrine, immune and circadian systems via multiple pathways, forming a vicious circle to aggravate DCI symptoms. Huanglian Wendan Decoction (HLWDD), a classic traditional Chinese medicine herbal formula, shows potential therapeutic effects on DCI by targeting the gut microbiota-the core node of MGBA. Notably, most relevant evidence is derived from animal preclinical models. This Mini Review succinctly summarizes the core pathological mechanisms of gut microbiota dysbiosis inducing DCI via MGBA, and elaborates HLWDD's multi-target therapeutic effects on DCI centered on gut microbiota regulation: reshaping gut microbiota composition, promoting short-chain fatty acids (SCFAs) production, and protecting intestinal mucosal barrier integrity, as well as improving central nervous system dysfunction via MGBA bidirectional regulation. We also discuss the existing academic controversies, critical research gaps and potential future development directions in this field. This review highlights the gut microbiota as a key therapeutic target of HLWDD for DCI, and provides a scientific basis for its clinical application and translational research via MGBA modulation.",

However, increasing evidence indicates that SCI can also induce neuroinflammation, cognitive decline, and emotional disorders in remote brain regions, suggesting that its pathological impact is systemic rather than purely local. Remote brain dysfunction after SCI is unlikely to be driven by a single pathway, but may arise from the combined effects of systemic inflammation, autonomic imbalance, neuroendocrine dysregulation, and disruption of intestinal homeostasis. Unlike previous reviews that mainly discuss SCI-associated gut dysbiosis, neuroinflammation, or gut-brain communication separately, this review organizes SCI-related intestinal abnormalities around the concept of \"gut-derived pathological signals\" and further distinguishes direct SCI evidence from cross-disease mechanistic evidence and proposed mechanistic inference. Specifically, we summarize how intestinal dysmotility, microbial metabolic remodeling, abnormalities in short-chain fatty acids (SCFAs), barrier vulnerability, and mucosal immune imbalance after SCI may generate persistent pathological signals. We then analyze how these signals may affect the central nervous system through an immune-inflammatory main axis, a vagal neural relay branch, and a neuroendocrine modulatory branch, ultimately converging on a common downstream brain effector stage characterized by blood-brain barrier impairment, neuroinflammation, synaptic plasticity deficits, and dysfunction of key brain regions such as the hippocampus and medial prefrontal cortex (mPFC). Based on this cascade, we propose a stratified intervention framework involving upstream restoration of intestinal homeostasis, midstream regulation of interorgan transmission pathways, and downstream protection of brain effector mechanisms. Overall, this review provides an evidence-stratified gut-brain axis framework for understanding remote brain dysfunction after SCI and highlights the need for SCI-specific temporal mapping and pathway-selective causal validation.",

Emerging studies have suggested that gut microbiota may influence glioma progression through the gut-brain axis, though the precise mechanisms remain largely unclear. In this study, we employed a comprehensive multi-omics approach-encompassing single-cell transcriptomics, spatial transcriptomics, metagenomics, metabolomics, and m6A-seq-to investigate how antibiotic-induced gut microbiota disruption impacts glioma progression in a mouse model. Gene expression analysis revealed significant alterations in antibiotics-treated mice (ABX-treated mice), including reduced expression of Epha6 and upregulated expression of Tead1, key genes associated with glioma progression and immune modulation. Spatial transcriptomics and metabolomic profiling identified reduced methionine levels in gliomas of ABX-treated mice, linking gut-derived metabolite changes to epigenetic regulation via m6A methylation. Single-cell RNA sequencing further demonstrated an increased proportion of AC-like cells, disrupted intercellular communication, and aberrations in the EPHA and NRXN signaling pathways. These findings highlight the interplay between gut microbiota, immune signaling, and epigenetic modifications in shaping the glioma microenvironment. This study advances our understanding of the gut-brain axis in glioma biology and proposes the EPHA pathway as a promising biomarker for the immune-mediated modulation of tumor progression, thereby providing new insights into the role of the gut-brain axis in glioma regulation.",

Given the central role of the gut in immune homeostasis, we investigated whether mucosal and peripheral molecular signatures relate to clinical status, immune recovery, and antiretroviral therapy (ART) class. Sixty-eight virologically suppressed PLWH were stratified by CDC clinical stage, ART regimen (integrase strand transfer inhibitor [INSTI]-based vs. non-INSTI), and CD4/CD8 ratio. Targeted gene expression was assessed by RT-PCR in anorectal mucosal biopsies and peripheral blood mononuclear cells, while epithelial protein expression was evaluated by Western blot in mucosal biopsies. Plasma biomarkers of epithelial injury, microbial translocation, and systemic inflammation were quantified by ELISA. Group comparisons and correlation analyses were performed using non-parametric statistics. Mucosal analyses revealed distinct transcriptional and protein-level alterations associated with clinical and immunological stratifications, whereas peripheral cellular and circulating biomarkers showed limited discriminatory capacity. Notably, specific ART-related patterns emerged at the mucosal level, accompanied by coordinated associations between epithelial junctional features and local immune parameters that were not mirrored systemically. Together, these findings indicate persistent, spatially restricted epithelial-immune remodelling in treated HIV infection, underscoring the importance of direct mucosal assessment to capture residual barrier and immune perturbations under suppressive ART.",

Although growing evidence implicates the gut-brain axis in neurodegeneration, the taxonomic and functional roles of the gut microbiome across the prodromal-to-symptomatic LBD continuum remain poorly defined. Here, we performed shotgun metagenomic sequencing on stool samples from 25 patients with LBD (10 mild cognitive impairment due to LBD [MCI-LB] and 15 dementia with Lewy bodies [DLB]), 10 individuals with iRBD, and their household matched cohabitant controls to characterize disease-associated microbial alterations while minimizing environmental confounding. Despite no significant differences in global microbial diversity, we identified convergent shifts in microbial taxa, metabolic pathways, and gene families across disease stages. Both LBD and iRBD showed increased abundance of microbial taxa potentially associated with gut barrier disruption, as well as higher abundance of functional pathways related to lipopolysaccharide biosynthesis. LBD showed lower abundance of pathways related to complex carbohydrate fermentation, and both groups showed lower abundance of pathways associated with neurotransmitter-related metabolism. In particular, pathways and gene families associated with starch degradation were reduced in LBD, and those associated with histidine-to-glutamate/ GABA metabolism were reduced in both groups. These exploratory findings represent the first high-resolution, shotgun metagenomic characterization of gut microbiome alterations across the LBD continuum, highlighting functional patterns that may serve as candidate markers of disease progression in future longitudinal and mechanistic studies.",

Microsecond irreversible electroporation (IRE) is a non-thermal ablation method whose mechanism of action on venous endothelium remains unclear. Using human umbilical vein endothelial cells (HUVECs) and a porcine hepatic portal vein model, we evaluated the killing efficacy, mechanism of action, and in vivo pathological changes induced by microsecond IRE at varying parameters. IRE killed venous endothelial cells in a parameter-dependent manner: apoptosis predominated at 400 V/cm, while necrosis predominated at 800 V/cm with high pulse counts. IRE activated the intrinsic apoptotic pathway via reduced mitochondrial membrane potential, elevated ROS, and calcium overload, while promoting release of DAMPs (ATP, HMGB1, vWF). In the porcine portal vein model, IRE induced early inflammatory and microthrombotic changes while preserving overall vascular wall architecture. Microsecond IRE achieves controllable, non-thermal venous endothelial injury and initiates signals necessary for venous closure, providing preclinical evidence for its development as a novel endovascular treatment for varicose veins.",
"42529162": "ID: 42529162\nTitle: Reframing brain aging: neuroinflammation as an interconnected network process.\nAbstract: Neuroinflammation has emerged as a central component of brain aging, shaping the balance between neural resilience and vulnerability to cognitive decline. Rather than representing a simple consequence of neuronal damage, neuroinflammatory processes are increasingly recognized as active regulators of synaptic integrity, neuronal survival, and circuit function. Under physiological conditions, neuroimmune signaling may contribute to tissue homeostasis, synaptic maintenance, and adaptive responses to cellular stress; however, persistent or dysregulated inflammatory activity may disrupt these functions, promoting network instability and increasing vulnerability to age-related pathology. These processes arise from complex interactions among neurons, glial cells, vascular elements, and peripheral immune signals that together form dynamic neuroimmune networks. Within the aging brain, microglia and astrocytes play key roles in coordinating immune surveillance, synaptic remodeling, and inflammatory signaling. Age-related alterations in glial function can disrupt homeostatic communication within neuron-glia networks, promoting persistent low-grade inflammation and altered synaptic regulation. Importantly, neuroinflammatory activity in the brain is strongly influenced by systemic factors, including peripheral immune aging, changes in blood-brain barrier integrity, and signals originating from the gut-brain axis. In this mini-review, we discuss brain aging from a network perspective, emphasizing how multiscale interactions between cellular and systemic processes shape neuroinflammatory trajectories across the lifespan. We further highlight emerging approaches-including multi-omics technologies, advanced neuroimaging, and systems-level analyses-that are enabling a more integrated understanding of neuroinflammatory dynamics. Viewing neuroinflammation as a network phenomenon may provide new insights into mechanisms of cognitive aging and identify potential targets for strategies aimed at preserving brain health.",

Among these sites, the gut has emerged as a particularly compelling candidate because it integrates microbial, epithelial, metabolic, and immune pathways with the potential to shape systemic inflammation. In this review, we examine the biological foundations of the gut-joint axis in rheumatoid arthritis, focusing on intestinal barrier structure, microbiome alterations, mucosal immune crosstalk, and mechanisms of barrier dysfunction. Current human evidence links rheumatoid arthritis to heterogeneous shifts in gut microbial composition, depletion of beneficial metabolite-producing commensals, altered immune-metabolic signaling, and biomarker patterns consistent with epithelial injury and microbial-product translocation. At the same time, available data do not support the existence of a single, universal microbial or permeability signature that defines the disease across populations. Recent longitudinal studies further challenge the concept of stable, long-standing dysbiosis and instead suggest a late, transient phase of ecological instability arising close to symptom onset. Experimental models provide stronger mechanistic support, showing that dysbiotic microbial communities, impaired barrier integrity, and strain-specific host-microbe interactions can promote T helper 17-skewed immunity and aggravate arthritis. Collectively, these findings support a context-dependent contribution of the gut to rheumatoid arthritis pathogenesis while underscoring the need for longitudinal, strain-resolved, and multi-omic human studies to clarify causality, refine disease models, and identify clinically meaningful windows for intervention.",

This study aimed to investigate the effects of probiotic supplementation on gut barrier function in combat athletes undergoing rapid weight loss prior to competition. Twenty-four elite male athletes were randomized to receive either a complex sports probiotic (1.5\u202f\u00d7\u202f1010 CFU, twice daily) or placebo for 4 weeks. Results showed that probiotic supplementation significantly reduced gastrointestinal symptoms and gut permeability markers (Zonulin, intestinal fatty acid-binding protein, D-lactate), increased secretory immunoglobulin A (SIgA) levels, and attenuated systemic inflammation compared to placebo. The intervention enriched beneficial butyrate-producing bacteria (Blautia, Latilactobacillus) while suppressing pathogenic Streptococcus. These findings demonstrate that probiotic supplementation serves as a safe, effective nutritional strategy to maintain gut homeostasis during rapid weight loss in combat athletes. http://www.chictr.org.cn, identifier ChiCTR2400079908.",

In recent years, more and more research has revealed that microglial responses to ischemic injury are highly heterogeneous and exhibit dynamic evolution over time, across brain regions, and under different metabolic states. This endows microglia with a dual regulatory role in both neurotoxicity and neuroprotection after ischemia: on one hand, they drive inflammatory responses, exacerbating secondary neuronal damage, blood-brain barrier disruption, and synaptic loss; on the other hand, they orchestrate debris clearance, vascular rebuilding, and neural repair. The traditional pro-inflammatory versus anti-inflammatory dichotomy is no longer sufficient to fully describe their complex functions. In this review we summarize recent advances in understanding the dual regulatory roles of microglia after ischemic stroke, with a focus on key mechanisms such as metabolic reprogramming, lipid metabolism regulation, inflammasome activation, and epigenetic modification. Furthermore, emerging therapeutic strategies targeting microglia and the challenges they face are discussed.",

The continued rise in prevalence of osteoporosis, particularly among younger populations, along with widespread adoption of HFD, has made the underlying mechanisms and preventative strategies related to HFD-induced osteoporosis a primary focus in the field of bone metabolism research. Early studies suggested that HFD-mediated weight gain might confer protective effects on skeletal health. However, emerging evidence reveals that HFD disrupts bone metabolic homeostasis and accelerates the progression of osteoporosis through multiple pathways, including pathological expansion of adipose tissue, systemic chronic inflammation, and gut microbial dysbiosis. The gut microbiota (GM) is a crucial mediator of dietary fat absorption and is increasingly recognized as a pivotal factor in the pathogenesis of HFD-associated osteoporosis. HFD-induced alterations in gut microbial composition and metabolic function compromise intestinal barrier integrity, triggering chronic systemic inflammation and metabolic disturbances that collectively exacerbate bone loss and promote osteoporosis. Targeted microbiota interventions have shown promise in ameliorating bone deterioration, paving the way for innovative therapeutic approaches against HFD-related osteoporosis. This review systematically examines the pathways through which HFD induces osteoporosis via modulation of GM, and evaluates emerging microbiota-focused treatment strategies.",

Resveratrol (RES), a pleiotropic polyphenol, has attracted increasing attention for its ability to modulate multiple molecular and cellular pathways implicated in PCOS pathophysiology. In this review, we synthesize current evidence to clarify how RES regulates key pathological signaling networks in PCOS, including ovarian follicular dysfunction, impaired insulin signaling, hyperandrogenism, oxidative stress, and vascular remodeling. Rather than merely cataloguing isolated mechanisms, we integrate findings from experimental models to highlight major convergent nodes-such as phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamycin (mTOR), sirtuin 1 (SIRT1)/AMP-activated protein kinase (AMPK), nuclear factor kappa-B (NF-\u03baB), and vascular endothelial growth factor (VEGF)-related pathways-through which RES may exert coordinated regulatory effects at the cellular and tissue levels. We further examine the available clinical studies to assess the translational relevance of these mechanistic insights, with particular emphasis on phenotypic heterogeneity, dose dependence, and the treatment window. Although clinical outcomes remain modest and variable, the available evidence suggests that RES may provide context-dependent benefits in selected PCOS subtypes. Collectively, this review offers a network-based framework linking the molecular actions of RES to the complex pathophysiology of PCOS and identifies key knowledge gaps that must be addressed to improve translational precision and therapeutic applicability.",

However, the cellular mechanisms underlying SiNPs-related injury remain incompletely understood. This study was designed to investigate whether ferroptosis contributes to SiNPs-mediated cytotoxicity in macrophages and to explore the potential regulatory role of microRNAs. RAW264.7 cells were exposed to SiNPs to establish an in vitro toxicity model. Mitochondrial ultrastructure and cellular uptake were examined. Ferroptosis-related markers, including antioxidant capacity, lipid peroxidation, ferrous iron accumulation, and the expression of glutathione peroxidase 4 (GPX4), acyl-CoA synthetase long-chain family member 4 (ACSL4), and cyclooxygenase-2 (COX2), were assessed. The involvement of apoptosis and necroptosis was evaluated using specific pathway inhibitors. Transcriptomic sequencing was performed to identify differentially expressed miRNAs, followed by functional validation through miR-339-5p mimic transfection, and the direct interaction between miR-339-5p and ACSL4 was verified by dual luciferase reporter assay. SiNPs were efficiently internalized by RAW264.7 cells and induced pronounced mitochondrial structural damage, characterized by mitochondrial shrinkage and loss of cristae. SiNPs exposure markedly impaired cellular antioxidant capacity and promoted the accumulation of lipid peroxides and intracellular Fe2+. This coincided with a reduction in GPX4 expression, whereas ACSL4 and COX2 levels increased. Ferroptosis was identified as the predominant mode of SiNPs-induced cytotoxicity, while apoptosis and necroptosis played minor roles. Transcriptomic analysis identified miR-339-5p as a potential regulator associated with ferroptosis-related pathways, and the dual luciferase reporter assay confirmed that miR-339-5p directly targets Acsl4. Overexpression of miR-339-5p significantly attenuated the ferroptosis response induced by SiNPs. SiNPs induce ferroptosis as the predominant mode of cell death in macrophages through mechanisms involving oxidative stress and lipid peroxidation. miR-339-5p acts as a negative regulator of this process by directly targeting ACSL4, alleviating ferroptotic injury and providing new insights into the molecular mechanisms underlying the toxicity of SiNPs.",
"42530574": "ID: 42530574\nTitle: The gut-brain-mitochondria axis in type 2 diabetes-associated cognitive decline: mechanistic convergence, biomarkers, and therapeutic opportunities.\nAbstract: Type 2 diabetes mellitus (T2DM) is increasingly recognized as a major risk factor for cognitive impairment and dementia, extending beyond its traditional metabolic complications. Emerging evidence suggests that cognitive decline in T2DM arises from a complex interplay among gut dysbiosis, chronic inflammation, impaired insulin signaling, blood-brain barrier dysfunction, and mitochondrial abnormalities. The gut-brain-mitochondria (GBM) axis has recently emerged as an integrated mechanistic framework linking peripheral metabolic disturbances to central neurodegenerative processes. Within this axis, alterations in gut microbial composition and function promote intestinal barrier disruption, endotoxemia, and aberrant production of microbial metabolites, which collectively contribute to systemic inflammation, neuroinflammation, and neuronal insulin resistance. Mitochondria occupy a central position in this network by regulating cellular bioenergetics, redox homeostasis, calcium signaling, and neuronal survival. Mitochondrial dysfunction amplifies oxidative stress, impairs synaptic plasticity, disrupts adult hippocampal neurogenesis, and accelerates neurodegenerative signaling pathways associated with cognitive decline. Furthermore, bidirectional communication between gut-derived metabolites and mitochondrial pathways influences neuronal resilience and disease progression. This review synthesizes current evidence describing the mechanistic convergence of gut dysbiosis, mitochondrial dysfunction, and neuroinflammation in T2DM-associated cognitive impairment. We also discuss emerging biomarkers, including mitochondrial DNA copy number, circulating lactate, lipopolysaccharide, zonulin, and microbial metabolite signatures, that may facilitate early disease detection and patient stratification. Finally, we critically evaluate therapeutic strategies targeting the GBM axis, including microbiota-directed interventions, mitochondrial-targeted antioxidants, metabolic modulators, and lifestyle-based approaches. Understanding the integrated role of the GBM axis may provide novel opportunities for precision-based interventions to prevent or slow diabetes-associated cognitive decline.",

We probed the extent to which specific gut bacterial taxa mediate the antidepressant effects of imipramine. Using a chronic unpredictable mild stress (CUMS) mouse model, we administered imipramine, the prebiotic inulin, or their combination, and systematically evaluated depressive-like phenotypes. Gut microbial dynamics were profiled by 16S rRNA sequencing, and fecal microbiota transplantation (FMT) was performed to determine the transmissibility of microbiota-derived antidepressant effects. Immunofluorescence staining was used to quantify brain-derived neurotrophic factor (BDNF) expression and to assess intestinal barrier integrity via ZO-1 and occludin. Imipramine treatment significantly increased the relative abundances of putative A. muciniphila and L. reuteri, both of which showed strong correlations with behavioral improvements. Furthermore, FMT from imipramine-treated donors effectively alleviated CUMS-induced depressive-like behaviors, upregulated BDNF expression and restored gut barrier integrity in recipient mice. Co-administration of imipramine and inulin produced synergistic antidepressant effects. Imipramine partially exerts its antidepressant activity through microbiota modulation, with putative A. muciniphila and L. reuteri emerging as important mediators. The superior efficacy of the imipramine-inulin combination highlights a promising microbiota-targeted strategy for advancing antidepressant therapy.",

In this study, we examined whether changes in Ca2+ and nitric oxide (NO) signalling were associated with ROS-related responses and cobalt-enhanced DTTAs production under cobalt stress. Co2+ treatment increased DTTAs accumulation together with intracellular hydrogen peroxide (H2O2), Ca2+ and NO levels. Among Ca2+ signalling inhibitors, neomycin (Neo) showed the strongest effect: 6 mM Neo reduced intracellular Ca2+ by 59.86%, DTTAs production by 33.70% and H2O2 levels by 25.50% compared with CoCl2 treatment. Time-course analysis further showed coordinated changes in H2O2, Ca2+ and DTTAs accumulation during fermentation. In contrast, L-NAME-mediated inhibition of NO synthesis did not significantly affect DTTAs production. These findings suggest that ROS-Ca2+ interplay is associated with cobalt-enhanced DTTAs accumulation in T. longibrachiatum UN32, whereas NO has a limited role under the tested conditions.",

Here, we applied an integrative computational and experimental strategy to identify key gut microbial metabolites and host genes potentially involved in PD. Differentially abundant gut microbes were obtained from the gutMDisorder database and their corresponding metabolites from gutMGene, with predicted protein targets generated using the Similarity Ensemble Approach. Transcriptomic data from PD brain tissues were analyzed to identify differentially expressed genes, which were intersected with metabolite targets, followed by enrichment and protein-protein interaction analyses. Three machine learning algorithms were applied for gene prioritization, while molecular docking evaluated metabolite-gene binding affinities and ProTox3.0 predicted toxicity and blood-brain barrier permeability. In vitro assays further assessed the functional effects of 3-indolepropionic acid in a rotenone-induced SH-SY5Y cell model. Our analyses identified 44 PD-associated microbial taxa linked to 77 metabolites and 905 predicted target genes, with 29 overlapping differentially expressed genes enriched in synaptic signaling and dopaminergic pathways. Dopamine receptor D2 (DRD2) emerged as a central hub gene, with strong docking interactions predicted for two indole metabolites, 3-(1H-indol-3-yl)propanoate and 3-indolepropionic acid. Functional validation showed that 3-indolepropionic acid improved cell viability, reduced apoptosis, and preserved DRD2 expression under neurotoxic stress. Together, these findings suggest that specific gut microbial metabolites may modulate host dopaminergic signaling via DRD2, offering new insights into the microbiota-brain axis and potential targets for further PD research.",

This study evaluated the effects of Lactobacillus plantarum 1582-fermented red onion bulb extract (LFRO), supplied through drinking water, on growth performance, cecal microbiota, and excreta gas emissions in heat-stressed yellow-feather chickens. A total of 300 one-day-old male Rilai chicks were assigned to four treatments in a completely randomized design with five replicate pens of 15 birds each: unsupplemented control or LFRO at 25, 50, or 100\u00a0mg/L in drinking water. Birds were reared for 70 days under natural chronic tropical heat stress, with the temperature-humidity index predominantly within the severe-to-very severe range (28.9-31.1). Supplementation with 100\u00a0mg/L LFRO increased final body weight and body weight gain, reduced feed intake, and improved feed conversion ratio over the whole trial. The European Production Efficiency Index and Broiler Performance Efficiency Factor were also highest in the 100\u00a0mg/L group. Cecal 16\u00a0S rRNA sequencing showed no major changes in alpha- or beta-diversity, but several selected bacterial genera were modulated. LFRO at 50 and 100\u00a0mg/L reduced ammonia emission from excreta, whereas the other measured gases were not affected. This study shows LFRO at 100\u00a0mg/L is a natural drinking water supplement that improves feed efficiency and gut microbial balance in yellow-feathered chickens exposed to chronic tropical heat stress.",

Evidence was assessed in relation to PS molecular weight, branching, charge, monosaccharide composition, purity, fermentability, dosage and associated non-carbohydrate constituents. Particular attention was given to gut microbiota modulation, short-chain fatty acid (SCFA) production, barrier integrity, immune signaling, microglial activation and neurodegenerative biomarkers.Results: Fermentable plant PS altered gut microbial composition and increased acetate, propionate and butyrate production in experimental models. These SCFAs may influence brain aging through FFAR2/FFAR3 signaling and histone deacetylase inhibition, thereby improving intestinal barrier function, regulating peripheral inflammation and modifying microglial responses. Direct anti-amyloid effects were supported mainly by in vitro studies, whereas evidence for tau modulation remained indirect and predominantly preclinical. Animal studies provided the strongest causal support, particularly through microbiota-transfer, antibiotic-depletion and receptor-pathway experiments. Human evidence was limited to associative studies and small fiber or prebiotic trials. Reported PS molecular masses ranged from about 10 kDa to more than 1,000 kDa, with preclinical doses of 50-500 mg/kg and human intakes of 5-15 g/day.Discussion: Plant PS are promising dietary modulators of brain aging but not established neurotherapeutics.

Heme induces degradation of the heme biosynthetic enzyme, 5-aminolevulinate synthase (ALAS), by the mitochondrial caseinolytic protease complex CLPX-CLPP (CLPXP), but the mechanism for heme-triggered degradation had not been elucidated. We found that polymerase delta-interacting protein 2 (POLDIP2) is a heme-sensing adaptor protein sufficient to reconstitute negative feedback degradation of ALAS by CLPXP. POLDIP2 was necessary to support ALAS turnover in cells and regulate heme production during erythropoiesis. POLDIP2 directly recognized and recruited heme-bound ALAS to CLPXP. Degradation initiation required a carboxyl-terminal element of ALAS, truncations of which cause an erythropoietic protoporphyria. Our findings establish a mechanism for conditional degradation by CLPXP that underlies erythropoietic protoporphyrias linked to CLPX and ALAS.",

Curdlan, a Food and Drug Administration-approved microbial exopolysaccharide, is widely used as a food additive, but its role in modulating the gut-liver axis to combat NAFLD has never been explored. Here, we demonstrate that curdlan alleviates high-fat and fiber-deficient (HFFD) diet-induced NAFLD by orchestrating gut microbiota remodeling and enhancing gut-liver crosstalk associated with the enrichment of butyrate-producing bacteria. In the mouse model of NAFLD, curdlan significantly attenuated hepatic steatosis, inflammation, and M1 macrophage infiltration. Hepatic transcriptome analysis revealed that curdlan modulated immune response and metabolism pathways, as further evidenced by the improvement of the NF\u03baB-PTP1B-Akt signaling axis. Crucially, curdlan reversed gut barrier disruption by enhancing tight junction proteins and enriching butyrate-producing genera (Clostridium_sensu_stricto_1, Anaerovorax, Roseburia, Turicibacter, and others), thereby increasing serum butyrate levels. Integrative correlation analysis revealed a significant correlation between butyrate-producing bacteria, increased serum butyrate levels, reduced serum lipopolysaccharide, and downregulated hepatic proinflammatory cytokines. Strikingly, Clostridium butyricum supplementation recapitulated the protective effects of curdlan, suggesting a role for butyrate in mediating gut-liver interactions. These findings establish curdlan as a novel prebiotic and metabolic modulator with therapeutic potential for NAFLD and support the translational application of functional food additives in metabolic disease management.",

Its pathogenesis is multifactorial, involving gut microbiota dysbiosis, metabolic dysfunction, and cellular senescence. Current therapeutic regimens remain limited, underscoring an urgent need for innovative agents that target these interrelated pathological cascades. This study aimed to evaluate the pharmacological effects of poricoic acid A (PAA) on DSS-induced senescence in intestinal epithelial cells and in a murine model of ulcerative colitis (UC), as well as the underlying molecular mechanisms. We established a DSS-stimulated senescent intestinal epithelial cell model and a DSS-induced UC mouse model. Multi-omics and bioinformatics strategies, including network pharmacology, transcriptome profiling, gut metagenomics, and intestinal targeted metabolomics, were combined with molecular docking to predict candidate signaling axes. Subsequent pharmacological inhibition and siRNA-mediated silencing assays were performed to validate core pathways functionally. PAA robustly suppressed DSS-induced senescence and inflammatory responses in intestinal epithelial cells. In vivo assays verified that PAA alleviated UC-related manifestations, including body weight loss, rectal hemorrhage, and colonic histological injury. Joint network pharmacology and transcriptomic screening identified the AMPK/PPAR\u03b3 as the core pathway mediating PAA's bioactivity. Mechanistic experiments confirmed that PAA directly bound and activated PPAR, further functionally triggering downstream AMPK/SirT1/PGC1\u03b1 signaling. Blockade of AMPK via pharmaceutical antagonists or siRNA largely abolished PAA's anti-senescence and anti-inflammatory capacities; PPAR\u03b3 suppression, in turn, secondary deactivated the AMPK and its downstream functional effectors. In mouse models, AMPK inhibition drastically compromised PAA's protective effects against UC. Moreover, PAA treatment of UC is closely associated with remodeling of the gut microbiome-metabolome axis and restoration of intestinal homeostasis. PAA exerts potent anti-senescence, anti-inflammatory, and colon-protective effects in UC via activating the AMPK/PPAR\u03b3 signaling pathway. Such beneficial activity may be associated with the normalization of gut microbiota-metabolome homeostasis. This work identifies novel molecular targets and a promising lead compound for the intervention of ulcerative colitis.",

(PM) can induce hepatotoxicity, particularly with prolonged use. Traditional processing methods, notably steaming (SPM) and steaming with black bean decoction (PPM), are recognized for their ability to mitigate this toxicity; however, the underlying mechanisms, especially from the gut-liver axis perspective, remain poorly understood. This study aims to clarify the mechanism by which processing reduces PM-induced hepatotoxicity, with a particular focus on the regulation of the gut-liver axis. We employed a comprehensive approach integrating histopathological examination, multi-omics analyses (including 16S rRNA sequencing, transcriptomics, and metabolomics), and molecular analysis to investigate the distinct effects of PM, SPM, and PPM in a mouse model. PM caused significant liver injury, characterized by elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and severe pathological damage. This damage was marked by intestinal barrier disruption (decreased tight junction protein-1 (ZO-1) and occludin), systemic inflammation (elevated tumor necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-6 (IL-6) levels), and activation of the hepatic nuclear factor-kappa B (NF-\u03baB) pathway. Multi-omics analysis revealed that PM induced severe GM dysbiosis (e.g., reduction in the Lactobacillus and a significant increase in the unclassified_f_Oscillospiraceae), a marked decrease in short-chain fatty acids (SCFAs) (e.g., a 72% reduction in butyrate), and disruption of the hepatic bile acid profile. Notably, the two processed products, particularly PPM, significantly reversed these alterations. Compared to the PM group, PPM treatment reduced serum ALT by 82% and exerted extensive protective effects. It restored beneficial bacteria, increased SCFAs levels, normalized bile acid metabolism, and suppressed the hepatic fibrogenic/NF-\u03baB inflammatory axis. This detoxifying effect may be associated with reduced systemic exposure to toxic stilbene glycosides and anthraquinones in the processed PM groups compared to the PM group. This study suggests that processing, particularly with black bean decoction (PPM), can alleviate PM-induced hepatotoxicity by reshaping the GM, restoring its metabolic products (SCFAs), normalizing bile acid signaling, and downregulating the FXR/NF-\u03baB inflammatory axis within the gut-liver axis. These findings provide a mechanistic basis for the clinical preference for processed PM products and highlight the importance of stringent quality control, while also underscoring that residual risk may persist, particularly in susceptible populations.",
"42532352": "ID: 42532352\nTitle: Poricoic acid A alleviates depressive-like behaviors by targeting the gut microbiota-immune axis.\nAbstract: Poricoic acid A (PAA) is a bioactive triterpenoid from the fungus Poria cocos. Nevertheless, whether it exerts antidepressant-like effects and whether the gut microbiota and immune regulation are involved remain unknown. Male C57BL/6J mice were subjected to chronic unpredictable stress (CUS) and treated with PAA treatment. Behavioral tests were performed, and hippocampal damage was evaluated by H&E and TUNEL staining. Gut microbiota composition was analyzed using 16S rRNA sequencing, and hippocampal transcriptomic profiling was performed using RNA-seq, followed by immune cell infiltration, correlation, and functional enrichment analyses. PAA treatment eased CUS-induced depression- and anxiety-like behaviors. It also cut down hippocampal neuron damage and cell death. Besides, PAA fixed gut bacteria balance by lowering harmful germs like L. murinus and boosting good germs like A. muciniphila and L. reuteri. Hippocampal transcriptomic analysis revealed that PAA modulated immune cell infiltration by reducing M1 macrophages and restoring M2 macrophages, with significant correlations between gut microbial taxa and hippocampal immune-related gene expression. Functional enrichment analyses indicated that PAA regulates pathways related to synaptic plasticity, neuroinflammation, and neuronal development. qPCR and western blotting confirmed that PAA restored the hippocampal expression of key molecules involved in neuroinflammation (HSP90B1), synaptic plasticity (RPS6KB2 and IGF2BP2), and blood-brain barrier integrity (COL4A5) CONCLUSIONS: PAA alleviates depression-like Behaviors in CUS mice by remodeling the gut microbiota and modulating the hippocampal M1/M2 macrophage balance via the gut-brain axis. These findings support the potential of PAA as a prebiotic-like nutritional agent for major depressive disorder.",

The Microbiota-Gut-Brain Axis (MGBA) serves as a central regulatory system orchestrating neurodevelopment, neural homeostasis, and immune-metabolic balance. This review summarizes evidence across seven major neuropsychiatric disorders, Depression, Autism Spectrum Disorder, Attention-Deficit/Hyperactivity Disorder, Alzheimer's disease, Schizophrenia, Anxiety and Obsessive Compulsive Disorder, demonstrating that dysregulation of the MGBA constitutes a shared pathological mechanism. On this common basis, we delineate disorder specific neurochemical and immunological features and highlight the clinical potential of microbiota-targeted interventions. Moreover, psychotropic medications profoundly alter microbial physiology, influencing bacterial growth and metabolism, thereby complicating interpretation of MGBA-disease relationships. Future research should define strain-specific therapeutic actions and integrate multi-omics approaches to unravel causal pathways, ultimately enabling precision microbiome modulation in neuropsychiatric medicine.",
"42532542": "ID: 42532542\nTitle: [Research progress on the bidirectional relationship between oral infectious diseases and mental health issues].\nAbstract: Infectious oral diseases represent the most prevalent categories of oral conditions, including dental caries, periodontitis, periapical lesions, and pericoronitis. Their bidirectional relationship with mental health has emerged as a critical interdisciplinary research frontier. This paper integrates epidemiological findings and molecular mechanism evidence to analyze the significant comorbidity and correlation characteristics between infectious oral diseases such as caries and periodontitis, and psychological disorders including depression and anxiety. Oral diseases not only directly impair mental well-being through pain, functional impairment, and social anxiety, but also induce systemic inflammatory responses that disrupt the blood-brain barrier, activate microglia, and alter neurotransmitter metabolism, thereby contributing to functional dysregulation within emotional regulatory centers. The dysbiosis of the oral microbiota caused by infectious oral diseases plays a central role in the vicious cycle of \"oral infection-mental health disorders\" through the\"oral-gut-brain axis\", inflammation-mediated neuroimmune cascades, and hypothalamic-pituitary-adrenal axis dysregulation. Meanwhile, mental disorders exacerbate oral microbial imbalance and tissue destruction through poor oral hygiene behaviors, xerostomia induced by psychotropic medications, and stress-related neuroendocrine alterations. This paper advocates for synergistically integrate oral clinical interventions with mental health improvement strategies, and for the development of microbiome-targeted precision modulation approaches. It further proposes an integrated health management paradigm that bridges dentistry and psychiatry, providing both theoretical foundations and practical pathways to transcend traditional disciplinary boundaries and achieve holistic oral-mental co-management. \u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u662f\u53d1\u75c5\u7387\u8f83\u9ad8\u7684\u4e00\u7c7b\u53e3\u8154\u75be\u75c5\uff0c\u4ee5\u9f8b\u75c5\u3001\u7259\u5468\u75c5\u3001\u6839\u5c16\u5468\u75c5\u3001\u51a0\u5468\u708e\u4e3a\u4ee3\u8868\uff0c\u5176\u4e0e\u5fc3\u7406\u75be\u75c5\u7684\u53cc\u5411\u5173\u8054\u5df2\u6210\u4e3a\u8de8\u5b66\u79d1\u7814\u7a76\u7684\u91cd\u8981\u524d\u6cbf\u3002\u672c\u6587\u6574\u5408\u4e86\u6d41\u884c\u75c5\u5b66\u4e0e\u5206\u5b50\u673a\u5236\u7814\u7a76\u8bc1\u636e\uff0c\u5206\u6790\u9f8b\u75c5\u3001\u7259\u5468\u708e\u7b49\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u4e0e\u6291\u90c1\u3001\u7126\u8651\u969c\u788d\u7b49\u5fc3\u7406\u5065\u5eb7\u95ee\u9898\u4e4b\u95f4\u5b58\u5728\u7684\u663e\u8457\u5171\u75c5\u5173\u7cfb\u4e0e\u76f8\u5173\u6027\u3002\u53e3\u8154\u75be\u75c5\u4e0d\u4ec5\u901a\u8fc7\u75bc\u75db\u3001\u529f\u80fd\u969c\u788d\u4e0e\u793e\u4ea4\u7126\u8651\u76f4\u63a5\u635f\u5bb3\u5fc3\u7406\u5065\u5eb7\uff0c\u8fd8\u53ef\u80fd\u8bf1\u53d1\u7cfb\u7edf\u6027\u708e\u75c7\u53cd\u5e94\uff0c\u901a\u8fc7\u7834\u574f\u8840\u8111\u5c4f\u969c\u3001\u6fc0\u6d3b\u5c0f\u80f6\u8d28\u7ec6\u80de\u53ca\u6539\u53d8\u795e\u7ecf\u9012\u8d28\u4ee3\u8c22\u76f4\u63a5\u53c2\u4e0e\u60c5\u7eea\u8c03\u8282\u4e2d\u67a2\u7684\u529f\u80fd\u7d0a\u4e71\u3002\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5\u6240\u81f4\u7684\u53e3\u8154\u83cc\u7fa4\u7a33\u6001\u5931\u8861\uff0c\u53ef\u901a\u8fc7\u201c\u53e3\u8154-\u80a0-\u8111\u8f74\u201d\u3001\u708e\u75c7\u4ecb\u8d28\u9a71\u52a8\u7684\u795e\u7ecf\u514d\u75ab\u708e\u75c7\u7ea7\u8054\u53cd\u5e94\u4ee5\u53ca\u4e0b\u4e18\u8111-\u5782\u4f53-\u80be\u4e0a\u817a\u8f74\u529f\u80fd\u7d0a\u4e71\u7b49\u5728\u201c\u53e3\u8154\u611f\u67d3\u6027\u75be\u75c5-\u5fc3\u7406\u5065\u5eb7\u969c\u788d\u201d\u6076\u6027\u5faa\u73af\u4e2d\u8d77\u5230\u6838\u5fc3\u4f5c\u7528\u3002\u540c\u65f6\uff0c\u5fc3\u7406\u75be\u75c5\u53ef\u901a\u8fc7\u53e3\u8154\u536b\u751f\u884c\u4e3a\u9000\u5316\u3001\u7cbe\u795e\u7c7b\u836f\u7269\u6240\u81f4\u53e3\u5e72\u75c7\u53ca\u5e94\u6fc0\u76f8\u5173\u795e\u7ecf\u5185\u5206\u6ccc\u6539\u53d8\uff0c\u663e\u8457\u52a0\u5267\u53e3\u8154\u83cc\u7fa4\u5931\u8c03\u4e0e\u7ec4\u7ec7\u7834\u574f\u3002\u672c\u6587\u63d0\u51fa\u5e94\u63a8\u52a8\u53e3\u8154\u4e34\u5e8a\u5e72\u9884\u4e0e\u5fc3\u7406\u5065\u5eb7\u6539\u5584\u7684\u534f\u540c\uff0c\u53d1\u5c55\u4ee5\u5fae\u751f\u7269\u7ec4\u4e3a\u9776\u70b9\u7684\u7cbe\u51c6\u8c03\u63a7\u7b56\u7565\uff0c\u6784\u5efa\u878d\u5408\u53e3\u8154\u533b\u5b66\u4e0e\u7cbe\u795e\u533b\u5b66\u7684\u7efc\u5408\u5065\u5eb7\u7ba1\u7406\u8303\u5f0f\uff0c\u4e3a\u7a81\u7834\u4f20\u7edf\u5355\u79d1\u8bca\u7597\u5c40\u9650\u3001\u5b9e\u73b0\u53e3-\u5fc3\u5171\u6cbb\u63d0\u4f9b\u7406\u8bba\u4f9d\u636e\u4e0e\u5b9e\u8df5\u8def\u5f84\u3002.",
"42532671": "ID: 42532671\nTitle: Decompression of portal hypertension by transjugular intrahepatic portosystemic shunt reverses markers of gut barrier dysfunction and cirrhosis-associated immune dysfunction.\nAbstract: Decompensated cirrhosis is associated with cirrhosis-associated immune dysfunction (CAID), predisposing patients to bacterial infections and poor outcomes. The mechanisms driving CAID remain incompletely understood. To examine whether portal hypertension (PH) is a key upstream driver of CAID and whether its reduction by transjugular intrahepatic portosystemic shunt (TIPS) reverses immune dysfunction. In a prospective cohort study, patients undergoing TIPS (n=75) and controls with compensated cirrhosis (n=15) were included. Plasma markers of gut barrier dysfunction, bacterial translocation, systemic inflammation and monocyte activation were measured in controls and longitudinally before and after TIPS. The effects of patient sera from different stages of cirrhosis on healthy donor-derived monocytes were assessed in vitro. Bulk RNA sequencing was performed on patient monocytes. Immunological findings were correlated with clinical outcomes, which were also validated in an external prospective cohort and a retrospective multicentre cohort of 1180 patients. Patients with decompensated cirrhosis showed elevated markers of gut barrier dysfunction, bacterial translocation, systemic inflammation and monocyte activation compared with compensated controls. These markers significantly decreased after TIPS. Sera from decompensated patients, but not from post-TIPS patients, induced anti-inflammatory markers (MER Tyrosine Kinase (MERTK), CD163) and suppressed interleukin 6 secretion in monocytes in vitro. Transcriptomic analysis identified an anti-inflammatory monocyte signature in decompensated cirrhosis that resolved after TIPS. CAID improvement occurred only in patients with ascites resolution and was associated with fewer bacterial infections. PH is a central driver of CAID in decompensated cirrhosis. Its reduction by TIPS restores gut barrier integrity, reduces inflammation and re-establishes immune homeostasis.",
"42532957": "ID: 42532957\nTitle: Two Mechanisms One Molecule: Developing a 'Truly' Bifunctional Degrader Targeting Rpn13 and CRBN.\nAbstract: Targeted protein degradation (TPD) has emerged as a powerful strategy to eliminate disease-relevant proteins, yet current approaches remain largely constrained to hijacking ubiquitin ligases. We previously introduced ByeTACs, bifunctional molecules that directly recruit proteins to the proteasome for E-ligase independent degradation. Here, we report \"Truly\" degraders, a new class of dual-mechanism molecules that combine a ligand for the proteasomal receptor Rpn13 with a ligand for cereblon (CRBN) to simultaneously engage both ubiquitin-independent and ubiquitin-dependent degradation pathways. Structure-guided design identified an optimal linker length that supports efficient substrate processing, with the PEG4 derivative (Truly-4) inducing robust depletion of both Rpn13 and CRBN in several cancer cell types. Remarkably, Truly-4 is the first noncovalent small molecule shown to degrade full-length Rpn13, a target previously approached using covalent or domain-restricted strategies. Mechanistic studies confirmed that degradation of Rpn13 proceeds via CRBN-dependent E3 ligase activity, whereas CRBN degradation occurs through an E-ligase independent process, consistent with a ByeTAC mechanism. Importantly, Truly-4 induces selective cytotoxicity in hematologic and solid cancer cell lines but not in healthy cells, despite comparable Rpn13 depletion, indicating that dual degradation can uncouple target engagement from toxicity. These findings establish a generalizable framework for engineering bifunctional degraders that program the proteasome to execute parallel degradation mechanisms and highlight proteasome receptors as druggable nodes for selective destruction of disease-relevant proteins.",
"42533008": "ID: 42533008\nTitle: Isolation and preliminary characterization of a glucan-type exopolysaccharide produced by Bacillus tequilensis strain HH from Egyptian fermented cucumber.\nAbstract: Exopolysaccharide (EPS) production is a common feature of microbial carbohydrate metabolism during fermentation; however, glucan-type EPS produced by Bacillus species in fermented vegetable systems remain insufficiently characterized. This study aimed to isolate an EPS-producing bacterium from naturally fermented cucumber and to perform a preliminary physicochemical and spectroscopic characterization of the produced polymer. An EPS-producing bacterial isolate was recovered and identified as Bacillus tequilensis, a member of the Bacillus subtilis species complex, based on 16\u00a0S rRNA gene sequence analysis. The extracellular polysaccharide was partially purified and analyzed using FTIR and \u00b9H NMR spectroscopy, revealing structural features consistent with a glucan-type EPS. Rheological analysis demonstrated a concentration-dependent increase in viscosity, confirming the macromolecular nature of the polymer in aqueous systems. Sucrose-hydrolyzing activity was detected under optimized conditions, indicating active carbohydrate metabolism associated with EPS production. In vitro cytocompatibility assessment using Vero and WI-38 cell lines showed high cell viability at low to moderate concentrations, with a dose-dependent reduction observed at higher levels. Overall, this study reports the isolation of an EPS-producing Bacillus tequilensis strain from Egyptian fermented cucumber and provides preliminary insights into the properties of its glucan-type exopolysaccharide, highlighting fermented vegetable microbiota as a potential source of functional biopolymers.",
"42533119": "ID: 42533119\nTitle: Comparative microbiome profiling of plant- and animal-derived traditional fermented foods from Mizoram, India using full-length 16S rRNA sequencing.\nAbstract: Traditional fermented foods represent complex microbial ecosystems shaped by substrate composition, indigenous processing practices, and local environmental conditions. However, the microbiomes of many traditional fermented foods from Northeast India remain poorly characterized. In this study, the bacterial communities associated with thirteen traditional fermented foods from Mizoram, India, representing both plant- and animal-derived fermentations, were characterized using full-length 16S rRNA gene sequencing on the Oxford Nanopore platform. Sequencing generated approximately 1.94 million high-quality reads, enabling high-resolution taxonomic profiling of the fermented food microbiomes. The microbial communities were predominantly composed of Bacillota, Pseudomonadota, and Cyanobacteriota, although their relative abundances varied considerably among fermented food types. Plant-derived fermented foods were enriched with fermentative bacterial genera, including Bacillus, Lactobacillus, Lacticaseibacillus, Pediococcus, and Weissella, whereas animal-derived fermented foods showed a greater abundance of anaerobic taxa, particularly Clostridium. Alpha diversity analyses demonstrated higher microbial richness in plant-derived fermented foods, while beta diversity revealed clear substrate-dependent clustering of microbial communities. Functional prediction indicated that metabolism-related pathways, particularly carbohydrate and amino acid metabolism, predominated across the fermented food microbiomes, and LEfSe analysis identified distinct microbial biomarkers associated with plant- and animal-derived fermentations. Collectively, these findings provide the first comprehensive microbiome characterization of traditional fermented foods from Mizoram and demonstrate that fermentation substrate is a major determinant of microbial community composition and predicted functional potential. Although full-length 16S rRNA gene sequencing improved taxonomic resolution, taxonomic interpretations were made cautiously at the genus level where appropriate because of the inherent limitations of 16S rRNA gene-based classification.",
"42533549": "ID: 42533549\nTitle: Doxorubicin-Induced Cytotoxicity in Adipose-Derived Stem Cells Is Associated With Altered SAPK/JNK Signaling.\nAbstract: Adipose-derived stem cells (ADSCs) are widely used in regenerative medicine, but their functionality declines under chemotherapeutic stress. Doxorubicin (Dox) is an effective anticancer agent known to induce long-term toxicity in healthy tissues. Increasing evidence suggests that Dox promotes cellular dysfunction, including apoptosis, promotion of oxidative stress, and premature senescence. The SAPK/JNK signaling pathway is implicated in stress responses and may contribute to Dox-induced aging in stem cells. However, its role in ADSC senescence and functional decline remains unclear. This study evaluated the effects of Dox on ADSC viability and aging-associated processes, with a focus on SAPK/JNK signaling. ADSCs exposed to 0.1-100\u2009\u03bcM Dox for 24\u2009h showed reduced mitochondrial activity and ATP levels at clinically relevant doses (5\u2009\u03bcM), along with disrupted cell cycle progression and cytoskeletal alterations. Dox induced both apoptosis and premature senescence and increased oxidative stress. These effects were accompanied by alterations in SAPK/JNK pathway expression. Overall, Dox promoted ADSC dysfunction, highlighting potential limitations in the therapeutic use of ADSCs during chemotherapy and emphasizing the need for protective strategies. Alterations in the SAPK/JNK signaling pathway were observed in response to Dox-induced stress, suggesting that this pathway may contribute to the cellular stress response. These findings suggest that the development of approaches to preserve ADSC function and mitigate Dox toxicity is critical for improving the safety and efficacy of regenerative medicine applications.",

Bats despite diverse dietary habits, making them ideal models for studying hypoglycemic mechanisms. In this study, we performed intraperitoneal glucose tolerance tests (IPGTTs) on five bat species three frugivorous or nectarivorous species (hereafter collectively referred to as frugivorous bats, given the high sugar content of both fruits and nectar) and two insectivorous species. A total of 704 known serum metabolites were analyzed quantitatively using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS). Compared with insectivorous bats, frugivorous bats exhibited significantly higher levels of amino acid-related metabolites under high-glucose stimulation. These included N-acyl amino acids, aromatic amino acid derivatives, and branched-chain amino acid metabolites, which were enriched significantly in pathways, such as alanine, arginine, and D-amino acid metabolism. Additionally, several known gut-brain axis (GBA) metabolites-such as neurotransmitters, bile acids, and short-chain fatty acids-exhibited strong host dietary and species specificity. Frugivorous bats were enriched in neurotransmitters and short-chain fatty acids associated with insulin regulation, whereas insectivorous bats exhibited relatively higher levels of bile acid metabolites. Overall, this study provides theoretical insights into the metabolic adaptations of frugivorous bats and the glucose-response strategies of insectivorous bats, offering new perspectives on metabolite-based therapeutic approaches to diabetes. \u73b0\u6709\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u624b\u6bb5\u4ecd\u7136\u6709\u9650\uff0c\u4e9f\u9700\u63a2\u7d22\u8840\u7cd6\u8c03\u63a7\u7684\u65b0\u673a\u5236\u3002\u8759\u8760\u5177\u6709\u9ad8\u5ea6\u591a\u6837\u5316\u7684\u98df\u6027\uff0c\u4e14\u666e\u904d\u8868\u73b0\u51fa\u8f83\u957f\u7684\u5bff\u547d\u7279\u5f81\uff0c\u8fd9\u4f7f\u5176\u6210\u4e3a\u7814\u7a76\u964d\u8840\u7cd6\u8c03\u63a7\u673a\u5236\u7684\u7406\u60f3\u6a21\u578b\u3002\u672c\u7814\u7a76\u5bf9\u4e94\u79cd\u8759\u8760\u5f00\u5c55\u4e86\u8179\u8154\u8461\u8404\u7cd6\u8010\u91cf\u8bd5\u9a8c\uff0c\u5176\u4e2d\u5305\u62ec\u4e09\u79cd\u98df\u679c\u6216\u98df\u871c\u8759\u8760\uff08\u9274\u4e8e\u6c34\u679c\u548c\u82b1\u871c\u5747\u5177\u6709\u8f83\u9ad8\u7684\u7cd6\u542b\u91cf\uff0c\u4e0b\u6587\u7edf\u79f0\u4e3a\u98df\u679c\u6027\u8759\u8760\uff09\u4ee5\u53ca\u4e24\u79cd\u98df\u866b\u8759\u8760\u3002\u91c7\u7528\u6db2\u76f8\u8272\u8c31-\u7535\u55b7\u96fe\u7535\u79bb-\u4e32\u8054\u8d28\u8c31\u6280\u672f\uff08LC-ESI-MS/MS\uff09\u5bf9\u9ad8\u7cd6\u523a\u6fc0\u4e4b\u4e0b\u8759\u8760\u8840\u6e05\u4e2d\u5171704\u79cd\u5df2\u77e5\u4ee3\u8c22\u7269\u8fdb\u884c\u4e86\u5b9a\u91cf\u5206\u6790\u3002\u7ed3\u679c\u663e\u793a\uff0c\u5728\u9ad8\u7cd6\u523a\u6fc0\u4e0b\uff0c\u4e0e\u98df\u866b\u8759\u8760\u76f8\u6bd4\uff0c\u98df\u679c\u8759\u8760\u4f53\u5185\u591a\u79cd\u6c28\u57fa\u9178\u76f8\u5173\u4ee3\u8c22\u7269\u6c34\u5e73\u663e\u8457\u5347\u9ad8\uff0c\u4e3b\u8981\u7c7b\u522b\u5305\u62ecN-\u9170\u57fa\u6c28\u57fa\u9178\u3001\u82b3\u9999\u65cf\u6c28\u57fa\u9178\u884d\u751f\u7269\u4ee5\u53ca\u652f\u94fe\u6c28\u57fa\u9178\u4ee3\u8c22\u7269\uff0c\u8fd9\u4e9b\u4ee3\u8c22\u7269\u663e\u8457\u5bcc\u96c6\u4e8e\u4e19\u6c28\u9178\u3001\u7cbe\u6c28\u9178\u548cD-\u6c28\u57fa\u9178\u4ee3\u8c22\u7b49\u901a\u8def\u3002\u6b64\u5916\uff0c\u591a\u79cd\u5df2\u77e5\u7684\u80a0-\u8111\u8f74\u76f8\u5173\u4ee3\u8c22\u7269\uff08\u5982\u795e\u7ecf\u9012\u8d28\u3001\u80c6\u6c41\u9178\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff09\u8868\u73b0\u51fa\u663e\u8457\u7684\u5bbf\u4e3b\u98df\u6027\u548c\u7269\u79cd\u6c34\u5e73\u7684\u7279\u5f02\u6027\u2014\u2014\u98df\u679c\u8759\u8760\u5bcc\u96c6\u4e86\u66f4\u591a\u7684\u4e0e\u80f0\u5c9b\u7d20\u8c03\u63a7\u76f8\u5173\u7684\u795e\u7ecf\u9012\u8d28\u548c\u77ed\u94fe\u8102\u80aa\u9178\uff0c\u800c\u98df\u866b\u8759\u8760\u5219\u8868\u73b0\u51fa\u6c34\u5e73\u76f8\u5bf9\u66f4\u9ad8\u7684\u80c6\u6c41\u9178\u4ee3\u8c22\u7269\u3002\u603b\u4f53\u800c\u8a00\uff0c\u672c\u7814\u7a76\u4e3a\u63ed\u793a\u98df\u679c\u8759\u8760\u7684\u4ee3\u8c22\u9002\u5e94\u673a\u5236\u53ca\u98df\u866b\u8759\u8760\u7684\u8461\u8404\u7cd6\u5e94\u7b54\u7b56\u7565\u63d0\u4f9b\u4e86\u66f4\u591a\u7406\u8bba\u4f9d\u636e\uff0c\u5e76\u4e3a\u57fa\u4e8e\u4ee3\u8c22\u7269\u7684\u7cd6\u5c3f\u75c5\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u89c6\u89d2\u3002.",

While essential for physiological processes-including cell signaling, proliferation, differentiation, immune defense, and neurotransmission-dysregulated ROS production contributes to oxidative stress and widespread biomolecular damage. This review outlines the major enzymatic and non-enzymatic mechanisms of ROS formation, emphasizing mitochondrial electron leakage, NADPH oxidase activity, and metal-catalyzed reactions. It further explores the impact of cold exposure, physical exercise, nutritional imbalance, and aging on ROS levels through alterations in mitochondrial function, calcium signaling, and antioxidant defenses. While ROS are vital for certain biological activities, the article also emphasizes their destructive potential. Particular attention is given to the vulnerability of mitochondrial DNA (mtDNA) and nuclear DNA to hydroxyl radical attack, resulting in base modifications, sugar lesions, tandem lesions, and DNA-protein cross-links. These lesions disrupt replication fidelity, impair DNA repair, and promote mutagenesis, ultimately threatening genomic stability. Finally, apoptosis is described as being modulated by ROS in a dose-dependent manner through the intrinsic, extrinsic, and ER-stress pathways, with the central role of p53 in determining cell fate being highlighted. Collectively, this review integrates current knowledge on ROS generation, physiological functions, stress-induced dysregulation, and the molecular mechanisms underlying oxidative damage, offering a comprehensive perspective on their implications for genomic integrity and disease development.",

Chronic neuroinflammation drives progressive retinal ganglion cell (RGC) loss independent of intraocular pressure, yet safe, sustained and precise neuroprotective modulation of the retinal inflammatory microenvironment remains a significant challenge. We developed an injectable fibrin gel delivery system loaded with ginseng-derived exosomes (GE-fibrin gel, GE-gel) to modulate microglial polarization, reduce retinal inflammation and promote RGC survival. In vitro, GE showed strong antioxidant and anti-apoptotic effects by getting rid of reactive oxygen species caused by oxidative stress and lowering apoptosis in R28 cells. Both GE and GE-gel stopped lipopolysaccharide from causing pro-inflammatory M1 polarization of microglia and increased anti-inflammatory M2 phenotypic change. Intravitreal injection of GE-gel suppressed pro-inflammatory microglial activation, diminished neuroinflammation and improved the survival of RGCs in a chronic ocular hypertension rat model. These results show that GE-gel could promote microglial polarization, change the immune environment in the retina and protect RGCs functionally over the long term. This approach may hopefully provide promising solutions for rapid and effective glaucoma therapy.",

Prior high-throughput sequencing showed specific follicular fluid exosomal miRNA profiles in DOR patients, implicating exosomal miRNAs in DOR pathogenesis. Using miRNA PCR arrays, we found miR-483-3p was significantly upregulated in DOR follicular fluid exosomes. Bioinformatics and experiments indicated METTL3 as a potential miR-483-3p target, suggesting excess miR-483-3p exerts cytotoxicity and suppresses METTL3-mediated N6-methyladenosine (m6A) modification. This study thus investigated miR-483-3p effects on METTL3 expression, m6A levels, cell proliferation, and mitochondrial function in ovarian granulosa cells (GCs). The targeting interaction between miR-483-3p and METTL3 was confirmed using a dual-luciferase reporter gene assay. qRT-PCR, immunofluorescence, Western blot, and Dot blot were used to evaluate the effects of miR-483-3p mimics, cyclophosphamide (CTX), and STM2457 on METTL3 protein expression and m6A modification levels in KGN cells. Additionally, Cell Counting Kit-8 (CCK-8) and 5-Ethynyl-2'-deoxyuridine (EdU) assays, along with mitochondrial membrane potential (MMP) measurements, were used to examine the impact of these treatments on KGN cell proliferation and mitochondrial function. miR-483-3p directly targeted the 3'\u00a0untranslated region (3'UTR) of METTL3, and its mimics significantly suppressed METTL3 gene expression. In contrast, CTX robustly promoted METTL3 gene expression, accompanied by a substantial elevation in global m6A levels. STM2457 treatment also showed a similar trend. But miR-483-3p overexpression modestly inhibited METTL3 protein and m6A levels. Regarding cellular phenotypes, miR-483-3p overexpression, CTX, and STM2457 all exerted significant inhibitory effects on KGN cells. All three treatments consistently suppressed the cell viability of KGN cells, reduced the EdU-positive cell ratio, and decreased MMP levels. This study provides preliminary evidence suggesting a specific regulatory interaction between miR-483-3p and METTL3. We demonstrate that aberrantly high expression of miR-483-3p significantly suppresses METTL3 mRNA levels but only moderately reduces METTL3 protein and m6A levels, suggesting the involvement of complex post-transcriptional regulatory mechanisms. Furthermore, overaccumulation of miR-483-3p markedly inhibits the proliferation of ovarian GCs and impairs their mitochondrial function. Further investigation into the role of the candidate miR-483-3p-METTL3-m6A axis in DOR will be conducted using in vivo models alongside an expanded cohort of clinical samples.",
"42534787": "ID: 42534787\nTitle: Microbiota-derived metabolites and cognitive dysfunction in dialysis patients: mechanisms and targeted therapeutic strategies.\nAbstract: Cognitive impairment (CI) in dialysis patients is a common and serious complication that significantly affects prognosis, with lack of effective treatment strategies. However, its mechanisms are still not fully clear, and effective treatment strategies are still limited. In recent years, more evidence has suggested that gut microbiota dysbiosis and changes in gut-derived metabolites may be involved in the development of CI in dialysis patients through the microbiota-gut-kidney-brain axis. Recent studies have shown that gut microbiota dysbiosis in dialysis patients may promote the progression of CI through several pathways. These include the accumulation of gut-derived uremic toxins, such as indoxyl sulfate (IS), p-cresyl sulfate (PCS), and Trimethylamine N oxide (TMAO), changes in bile acid metabolism; and the reduction of short-chain fatty acids (SCFAs) with neuroprotective effects. These changes may damage the intestinal barrier and the blood-brain barrier (BBB), and promote systemic inflammation, oxidative stress, and neuroinflammation. As a result, cognitive dysfunction in dialysis patients may be further aggravated. Therefore, targeting the gut microbiota has become a promising treatment direction. These strategies include dietary intervention, probiotics and related preparations, fecal microbiota transplantation (FMT), and targeted removal of uremic toxins and their derivatives. This review summarizes the gut microbiota composition associated with CI in dialysis patients, examines the molecular mechanisms of injury mediated by the microbiota-gut-brain-kidney axis, evaluates current microbiota-targeted interventions, and discusses future research directions for improving clinical prevention and treatment.",

This study employed bibliometric analysis to objectively review relevant literature, identify key research contributors, and uncover emerging frontiers in the field. Relevant literature published from 2009 to 2025 was retrieved from the Web of Science Core Collection (WoSCC) and Scopus databases. Bibliometric analyses were performed using the Bibliometrix R package, VOSviewer, and CiteSpace software to evaluate research outputs and generate visualizations. A total of 425 eligible articles from WoSCC and 514 from Scopus were included. Annual publications on SCFAs and cognitive impairment showed a continuous upward trend from 2009 to 2025. China contributed the largest number of publications in this field, and an international collaboration network has been established, with Wenzhou Medical University (China) serving as the core collaboration hub. International Journal of Molecular Sciences was identified as a major publication platform, and Zhang, Xin was recognized as a core author in SCFA-cognitive impairment research. High-frequency keywords included \"gut microbiota,\" \"Alzheimer's disease,\" \"neuroinflammation,\" and \"gut-brain axis.\" In addition, recent research frontiers encompassed \"drug therapy,\" \"microbiology,\" and \"chemistry,\" revealing the core themes and trends of SCFA and cognitive impairment studies. This study conducted a comprehensive bibliometric analysis of the association between SCFAs and cognitive impairment, clarified the evolutionary trajectory of research themes, and identified potential future research directions. It revealed a developmental pattern whereby research in this field has gradually advanced from exploring basic correlations between diet and gut microbiota to in-depth investigations of pathological mechanisms, precise targeted interventions, and clinical translational applications. By systematically depicting the current research landscape, this study aims to provide guidance for subsequent investigations and fill critical knowledge gaps.",

This review focuses on the transition from single-omics to integrative multi-omics analysis, which helps overcome the constraints of individual omics strategies and provides a more systematic understanding of PD pathogenesis. Key topics include the elucidation of core mechanisms (mitochondrial dysfunction, lipid metabolic disturbance, \u03b1-synucleinopathy, and gut-brain axis impairment), the development of biomarkers (shifting from invasive cerebrospinal fluid samples to less invasive plasma/urine panels with improved performance), and the identification of potential interventional targets (signaling pathways, key molecules, and gut microbiota). Technical advances include refined single-omics detection, AI-assisted multi-omics integration, and the emergence of multi-center large cohorts. Despite notable progress, major challenges remain, including limited sample diversity, insufficient technical standardization, and gaps between basic research and clinical translation. Future directions should prioritize the establishment of multi-center longitudinal biobanks, high-sensitivity detection methods, and clinical translation through precision subtyping and targeted intervention. Integrative multi-omics has significantly advanced PD research from fragmented studies to a more systematic framework, providing a foundation for early diagnosis and precision therapy. Further efforts are needed to address current limitations and translate findings into clinical benefit for PD patients.",
"42535110": "ID: 42535110\nTitle: The vagus nerve as a neurovisceral interface: a comprehensive review.\nAbstract: The vagus nerve is the longest cranial nerve and a key component of the autonomic nervous system, functioning as a neurovisceral interface between the brain and peripheral organs. Despite well-defined anatomy, the mechanisms underlying its integrative roles in cardiovascular, metabolic, and neuropsychiatric regulation remain incompletely understood. This narrative review synthesizes current evidence on the anatomical organization, physiological functions, and clinical relevance of the vagus nerve, focusing on cardiac autonomic control, gastrointestinal and metabolic regulation, the gut-brain axis, and vagus nerve stimulation. In the cardiovascular system, it interacts with sympathetic pathways within the cardiac plexus and intrinsic cardiac nervous system to regulate heart rate and conduction. In the gastrointestinal system, it coordinates motility, secretion, and metabolic homeostasis through nutrient- and hormone-sensitive pathways. Within the gut-brain axis, emerging evidence highlights rapid neuroepithelial signaling and microbiota-dependent modulation mediated by vagal circuits. The vagus nerve stimulation represents a promising therapeutic strategy for restoring autonomic balance, although challenges remain in fiber selectivity and clinical variability. Advances in multi-omics approaches are beginning to reveal the molecular heterogeneity of vagal neurons, but significant gaps persist due to limited human anatomical data. In conclusion, the vagus nerve functions as a multidimensional integrative system, and a deeper understanding of its structure and molecular organization is essential for developing precise neuromodulatory therapies.",

These pathological shifts facilitate the translocation of pathogen\u2011associated molecular patterns, thereby driving neuroinflammation and exacerbating intensive care unit\u2011acquired syndromes such as delirium and muscular wasting. Although conventional nutritional strategies emphasize caloric and protein goals, emerging evidence has highlighted the necessity of modulating the host\u2011microbiome interface to preserve neurological and systemic homeostasis. The integration of fermentable fibers, probiotics and specialized lipid mediators into a standardized framework may effectively interrupt the self\u2011perpetuating cycle of dysbiosis and organ failure. The present review uniquely contributes to the field by integrating an implementation science framework for clinical bundle application and discussing artificial intelligence driven precision nutrition advances, which are topics that have not been comprehensively covered in the majority of previous reviews.

Tangeretin (TAN), a polymethoxylated flavonoid derived from citrus fruit peel, exhibits relatively high structural stability due to its methoxy groups and exerts anticancer effects in various malignancies, including lung, liver and breast cancer. However, to the best of our knowledge, the anticancer effects of TAN in cervical cancer remain insufficiently explored. The present study investigated the mechanisms underlying the anticancer effects of TAN on the CaSki cervical cancer cell line. Cell viability was evaluated using the EZ\u2011Cytox cell viability assay. The colony formation and cell cycle arrest assays demonstrated that TAN inhibited cell proliferation by inducing G1 phase arrest. The wound\u2011healing and Transwell migration assays demonstrated that TAN could reduce the migratory ability of CaSki cells, and the Annexin V/propidium iodide staining assay revealed that TAN increased the apoptotic cell population. Mitochondrial reactive oxygen species (ROS) were identified using MitoSOX\u2122 staining and the mitochondrial membrane potential (MMP) was detected using JC\u20111 staining. The findings of these assays suggested that TAN could increase mitochondrial ROS levels and decrease mitochondrial MMP in CaSki cells. Western blot analysis showed that TAN upregulated the protein expression levels of E\u2011cadherin and Bax. In addition, TAN restored the tumor suppressor protein p53. Collectively, these findings suggested that may exhibit anticancer activity in CaSki cells.",
"42535497": "ID: 42535497\nTitle: The significance of inflammation and biomarkers of neurodegeneration in essential tremor: a systematic review.\nAbstract: Essential tremor (ET) is one of the most prevalent yet mechanistically unresolved movement disorders. Although traditionally attributed to cerebellar dysfunction, accumulating evidence indicates the involvement of broader systemic processes, including neuroinflammation, immune dysregulation, and neurodegeneration. However, the role of inflammation in ET remains insufficiently defined, particularly regarding whether it constitutes a primary pathogenic mechanism or a secondary response. This systematic review aimed to comprehensively evaluate current evidence on inflammatory, immune- related, and neurodegeneration-associated biomarkers in ET. A structured search of PubMed, Scopus, and Web of Science identified relevant studies published between 2000 and March 2026. Thirty-two studies fulfilled the inclusion criteria. Across clinical and molecular investigations, the available evidence was highly heterogeneous and frequently inconsistent. No reproducible inflammatory profile has been established, and reported alterations in cytokines, acute-phase proteins, and hematological indices varied substantially across cohorts. Although selected cytokines were associated with tremor severity and cognitive impairment, these associations lacked consistency and specificity. Similarly, biomarkers of neurodegeneration, including neurofilament light chain and \u03b1-synuclein, demonstrated variable and non-disease-specific alterations. Emerging evidence suggests the involvement of integrative mechanisms encompassing blood-brain barrier dysfunction, impaired glymphatic clearance, and gut-brain axis interactions, although direct evidence in ET remains limited. Current evidence does not support inflammation as a primary driver of ET and instead indicates that inflammatory processes may act as context-dependent modulators within a multifactorial disease framework. Further well-designed longitudinal and multimodal studies are required to clarify the causal role of inflammation and its relationship to neurodegenerative mechanisms in ET.",

"42535828": "ID: 42535828\nTitle: Microalgae Hybrid Biosystem for Enhanced Oral Delivery of Rifaximin in Hepatic Encephalopathy Treatment.\nAbstract: Hepatic encephalopathy (HE) is a serious neuropsychiatric complication of acute or chronic liver failure. It occurred in approximately 40% of acute liver failure cases and affected 30%-45% of patients with chronic liver failure or decompensated cirrhosis. Hyperammonemia is widely recognized as a central pathogenic factor in the pathogenesis of HE. Rifaximin (RIF), a non-absorbable oral antibiotic, was widely used to manage HE by modulating gut microbiota and reducing ammonia production. However, its clinical efficacy remained suboptimal due to poor aqueous solubility, limited dispersibility, and inadequate gastrointestinal retention. These limitations were further exacerbated in severe cases, owing to restricted oral dosing, recurrence associated with poor adherence, and potential risks of antimicrobial resistance and infection-related adverse events. This study presented a microalgae-nanoparticle hybrid system (SP@RIF) for drug delivery, in which RIF-encapsulated nanoparticles (RIFnano) were electrostatically loaded onto the surface of Spirulina platensis (SP), aiming to improve the oral delivery and therapeutic efficiency in HE treatment. RIFnano exhibited significantly enhanced antibacterial activity compared to free RIF. SP@RIF demonstrated prolonged gastrointestinal retention and sustained drug release profiles. In mouse models of HE, oral administration of SP@RIF markedly reduced systemic ammonia levels and improved behavioral outcomes. Furthermore, SP@RIF enhanced intestinal barrier function, attenuated systemic inflammation and neuroinflammation, ameliorated cognitive impairments, and modulated the gut microbiota. Importantly, these therapeutic benefits were achieved without observable toxicity. These findings highlight SP@RIF as a potential therapeutic strategy for treating HE.",

In this study, eleven bacterial isolates were obtained from different body parts (oral arms, gastric cavity, and mucus) of the jellyfish Chrysaora sp. collected from the coastal waters of Goa, India, and screened for exopolysaccharide (EPS) production. Among the screened isolates, Brevibacterium sp. JAB08 demonstrated the highest crude EPS production potential. Optimisation using a Box-Behnken Design coupled with response surface methodology identified sucrose 3% (w/v), inoculum size 2% (v/v), and an incubation period of 36\u00a0h as the optimal fermentation conditions with EPS yield of 4.26\u00a0g\u00a0l-1 in shake flask. Notably, this yield was achieved in 36\u00a0h, compared to 96\u00a0h required to reach a comparable yield under unoptimised conditions, indicating improved process efficiency, structural characterisation by FTIR revealed a neutral polysaccharide dominated by \u03b2-glycosidic linkages, while SEM revealed a porous, three-dimensional network of spheroidal aggregates.

Mitochondria dependent cell death is a key contributor, but the upstream regulatory networks and cell type specific effectors remain unclear. Single cell RNA sequencing, bulk RNA sequencing and miRNA profiling from mouse middle cerebral artery occlusion models were integrated to identify mitochondrial apoptosis related pathways and key regulators. Cell type composition and differentially expressed genes were analyzed by scRNA-seq, intersected bulk datasets were used to define shared apoptosis related genes, and miRNA target prediction nominated candidate miRNA-mRNA pairs. Hypoxia treated BV2 microglia and bEnd.3 endothelial cells were used for functional validation by qPCR, western blotting, flow cytometry, LDH release, CCK-8 and dual luciferase assays. scRNA-seq identified twelve brain cell populations and showed that endothelial cells, monocytes, astrocytes and microglia display the most prominent changes after ischemia, with Gene Ontology enrichment repeatedly highlighting \"apoptotic mitochondrial changes\" (GO:0008637). Intersecting two bulk RNA-seq cohorts recovered the same pathway and four candidates (Hk2, Pycard, Fas and Plaur), with Plaur most strongly dysregulated in endothelial and myeloid cells. miRNA profiling and multi database prediction highlighted miR-21a-3p as a putative upstream regulator of Plaur. In vitro, hypoxia increased Plaur and decreased miR-21a-3p. Plaur silencing reduced apoptosis, reactive oxygen species and LDH release and improved viability, while miR-21a-3p overexpression lowered Plaur and attenuated hypoxia induced injury; inhibition of miR-21a-3p had opposite effects. Dual luciferase assays confirmed direct binding of miR-21a-3p to the Plaur 3'UTR. The miR-21a-3p/Plaur axis links miRNA regulation to mitochondria associated apoptotic and oxidative damage pathways in ischemia related cellular models and represents a potential target for further mechanistic and translational studies in ischemic stroke.",

Ubiquitination modification is implicated in the pathogenesis of cardiovascular diseases through diverse biological processes. However, the role of TRIM9, an E3 ubiquitin ligase, in AD remains unexplored. In this study, the expression profiles of TRIM9 and SMAD4 were analyzed using clinical samples, as well as Angiotensin II (Ang II)-induced mouse and human aortic endothelial cell (HAEC) models. Endothelial barrier function in AD was assessed through CCK-8 assays, vascular permeability measurements, immunofluorescence staining, hematoxylin-eosin and Verhoeff's van Gieson staining, and Western blot analysis. The underlying molecular mechanisms were elucidated using quantitative real-time PCR, immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and enzyme-linked immunosorbent assay (ELISA). TRIM9 was markedly overexpressed, whereas SMAD4 was significantly downregulated in AD. Knockdown of TRIM9 attenuated endothelial permeability, preserved the endothelial barrier integrity, and inhibited pyroptosis both in vivo and in vitro. Mechanistically, TRIM9 promoted the ubiquitination and subsequent proteasomal degradation of SMAD4, thereby exacerbating AD progression. Collectively, these findings demonstrate that elevated TRIM9 expression aggravates AD progression through SMAD4 destabilization, offering novel therapeutic insights for AD management.",

However, how RNAPII respond to and are regulated during stress are poorly understood. We show that RNAPII is degraded during many types of cellular stresses. In osmotic stressed cells, the TNF\u03b1-p38 pathway was activated and promoted the neddylation of the CUL1 E3 ligase complex, which interacted with RPB1 through FBXO11 to ubiquitylate and degrade RNAPII. This caused genome wide RNAPII binding reduction, but prevented RNAPII binding loss from genes with low promoter GC content. This redistribution protected the RNAPII loss from stress response genes in the cell adhesion, MAPK and GPCR pathways. RNAPII redistribution is vital for cell survival, as degradation blockage resulted in the loss of RNAPII from low GC promoters and compromised stress response from disrupted cell adhesion to increased apoptosis. Thus, rapid RNAPII degradation and RNAPII redistribution are components of the cellular stress response to benefit cell survival.",

However, the potential intestinal toxicity of GAA is poorly studied. Here, the intestinal toxicity and the underlying mechanism were investigated in vivo using zebrafish and network toxicology. After exposure from 3\u202fdays post fertilization (dpf) to 6 dpf, GAA could notably affect the zebrafish gut barrier by reducing the microvilli and goblet cells, and subsequently affected the intestinal function, including decreasing the intestinal peristalsis and peristalsis number, endocytic capacity. In addition, GAA promoted the intestinal infiltration of neutrophil cells and cell death in the intestine. Furthermore, the mechanism study by network toxicology, molecular docking and RT-qPCR, showed that GAA could affect lipid metabolism, redox balance, apoptosis, inflammation and pyroptosis by regulating PPAR/NLRP3/GSDMD pathways. Taken together, these results will help to deeply understand GAA's harmful effects and underlying mechanisms.",

Mela Rosa Marchigiana Preserves Intestinal Barrier Integrity and Confers Neuroprotection in a Gut-Brain Axis Co-Culture Model.\nAbstract: The gut-brain axis is a key target in neuroinflammatory disorders. We investigated the protective effects of Mela Rosa Marchigiana pulp callus extract (MRME), a phytocomplex with a unique triterpenic profile. Using a validated transwell co-culture model of the intestinal-neural interface, differentiated Caco-2 cells formed a polarized epithelial barrier (apical), while BV2 microglia or SH-SY5Y neurons were seeded in the basolateral compartment. Apical MRME pretreatment preserved Caco-2 barrier integrity against lipopolysaccharide or dextran sodium sulfate-induced damage. MRME maintained occludin integrity and transepithelial electrical resistance (TEER), effectively neutralizing \"leaky gut\"-like conditions. By stabilizing the barrier, MRME exerted indirect neuroprotection since high-throughput live-cell imaging revealed dose-dependent reductions in reactive oxygen species generation and apoptosis (caspase-3/7 activation) in both BV2 and SH-SY5Y cells. MRME demonstrated a microbiologically neutral profile, exerting no inhibitory effects on either pathogenic or probiotic strains up to 10,000\u2009\u03bcg/mL. MRME provides dual protection by strengthening the intestinal barrier and shielding the neural environment from systemic inflammation through host cellular modulation rather than microbial interference. These findings suggest MRME as a promising nutraceutical candidate for gut-brain axis dysregulation.",
"42539437": "ID: 42539437\nTitle: Gastrointestinal axis in post-traumatic sepsis: from molecular mechanisms to translational perspectives.\nAbstract: Post-traumatic sepsis is the leading cause of late mortality in intensive care units. While the concept of \"gut-origin sepsis\" has evolved over the past three decades, the stomach has largely been overlooked as an active contributor. This review synthesizes current evidence and proposes a novel \"Gastrointestinal Axis\" (GIA) integrating gastric and intestinal dysfunction as interconnected drivers of post-traumatic sepsis, with gastric autophagy as a proposed regulatory node. The mechanistic data supporting this framework derive primarily from intestinal epithelial cells and general sepsis models; direct evidence for gastric mucosal autophagy in human post-traumatic sepsis remains limited, and the causal inference that gastric autophagy failure initiates downstream intestinal injury remains a hypothesis requiring further validation. A comprehensive literature search of PubMed, Web of Science, and Scopus was conducted to identify relevant peer-reviewed studies on gut barrier dysfunction, dysbiosis, autophagy, and immune responses in post-traumatic sepsis. The central mechanistic framework involves histone deacetylase 5 (HDAC5) upregulation silencing ghrelin, thereby impairing gastric autophagy-a proposed regulatory node in the GIA-which reduces E2F1-mediated NF-\u03baB suppression and impairs intestinal barrier integrity. Parallel protective pathways include PLK1-mTOR-regulated autophagy and SIRT3-mediated mitochondrial protection. This gastric dysfunction may propagate to the intestine, where dysbiosis with loss of obligate anaerobes and overgrowth of Enterobacteriaceae creates a \"pathobiome\" that potentially amplifies systemic inflammation. Bidirectional communication occurs via lymphatic, humoral, cellular, and neural routes. Emerging biomarkers such as intestinal fatty acid-binding protein, D-lactate, citrulline, and the Acute Gastrointestinal Injury grading system enable multimodal risk stratification. Early enteral nutrition (OR 0.36) and synbiotics (RR 0.61) show promise; preclinical data support HDAC5 inhibitors, ghrelin restoration, and teprenone as promising adjuncts for preserving GIA integrity. The GIA concept reframes gastric and intestinal protection as an integrated therapeutic strategy and provides a new conceptual foundation for preventing post-traumatic sepsis and guiding biomarker-driven mechanism-based interventions.",

Gut microbiota dysbiosis and gliosis following ischemic stroke are key drivers of post-stroke neurological impairment. Sodium oligomannate (GV-971) is a low-molecular-weight acidic oligosaccharide that targets the gut-brain axis. It alleviates gliosis and improves cognitive dysfunction by remodeling gut microbiota in Alzheimer's disease. However, it is still unknown whether GV-971 has pharmacological activity against ischemic stroke. Here, we explore the efficacy of GV-971 on infarct volume, gliosis, blood-brain barrier integrity, gut microbiota composition, and post-stroke cognitive impairment (PSCI) using a middle cerebral artery occlusion/reperfusion (MCAO/R) model in male Sprague-Dawley rats. Administer medication before surgery for 4 consecutive days and once after surgery, after stroke 24-hour triphenyltetrazolium chloride (TTC) staining revealed that 0.3 mg/kg GV-971 significantly reduced infarct volume in ischemic brain tissue from 37.81\u00b12.391% to 13.30\u00b14.801% and neurological impairment score of GV-971 treatment significantly decreased from 11.50\u00b10.54 to 7.29\u00b11.47. After stroke 24-hour immunofluorescence analysis of glial activation confirmed that GV-971 significantly reduced central inflammatory responses. Western blot combined with Evans blue staining collectively demonstrated that after stroke 24-hour, GV-971 exerts a significant protective effect on the blood-brain barrier. In the gut, GV-971 reversed microbial dysbiosis, as revealed by shotgun metagenomics, enhanced intestinal barrier integrity, and suppressed colonic inflammation. Antibiotic depletion abolished GV-971's neuroprotective effect, while fecal microbiota transplantation from GV-971-treated donors restored protection, supporting a microbiota-dependent contribution. Furthermore, GV-971-treated rats subjected to MCAO/R exhibited significant improvements in motor and cognitive function. For example, on day 35, Y-maze test results indicated that GV-971 administered either before MCAO/R (pre-treatment) or during the perioperative period (co-treatment) increased spontaneous alternation rate from 60.95\u00b14.91% to 85.60\u00b16.32% and 85.64\u00b15.027%. On day 32, novel object recognition assay results indicated that GV-971 treatment increased new-object exploration from 0.2039\u00b10.03752 to 0.3991\u00b10.1122 (pre-treatment) and 0.5066\u00b10.06982 (co-treatment). On day 42, Barnes maze test results indicated that GV-971 treatment reduced the time required to locate the target hole from 76.45\u00b117.41s to 31.03\u00b120.75\u2009s and 33.37\u00b119.30\u2009s for pre- and co-treatment, respectively.

"42539791": "ID: 42539791\nTitle: Inflammatory Bowel Disease and Risk of Periprosthetic Joint Infection After Total Joint Arthroplasty: A Systematic Review of the Current Literature.\nAbstract: Periprosthetic joint infection (PJI) is a severe complication after total joint arthroplasty (TJA). Inflammatory bowel disease (IBD) may plausibly increase this risk because of chronic systemic inflammation, intestinal barrier dysfunction, malnutrition, and exposure to immunosuppressive therapies; however, the available orthopedic literature is sparse and heterogeneous. This systematic review was revised in accordance with PRISMA 2020 principles and the PRISMA 2020 for Abstracts recommendations. The primary review question was whether patients with IBD undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) are at increased risk of PJI or septic revision. Cohort and case-control studies reporting arthroplasty-related infectious outcomes in patients with Crohn's disease, ulcerative colitis, or unspecified IBD were eligible for the primary analysis. To ensure the study is scientifically sound, case reports describing nonprosthetic osteomyelitis were excluded from the primary quantitative analysis and evaluated separately using CARE principles as contextual qualitative evidence. No prospective protocol registration was completed before the original review process. The revised review identified two retrospective cohort studies suitable for the primary analysis and two case reports retained in a separate qualitative appendix. The primary analysis included 22,320 arthroplasty patients with IBD studied against much larger non-IBD comparator cohorts. One THA registry study found a higher risk of septic revision in patients with IBD, whereas one TKA database study found higher postoperative PJI odds in both Crohn's disease and ulcerative colitis. Direct quantitative pooling was considered inappropriate because the studies differed in joint type, follow-up duration, and outcome definition. The currently available evidence suggests that IBD may be associated with an increased risk of infection-related failure after arthroplasty, but the certainty of evidence is low to very low because only two retrospective cohort studies directly addressed this question. Future research should use standardized PJI definitions, report disease activity and immunosuppressive treatment in detail, and prospectively evaluate whether the excess risk is related to IBD itself or to modifiable perioperative factors.",

Probiotic supplementation represents a microbiota-targeted nutritional strategy for functional constipation, but associated host-response signals remain incompletely understood. This single-center, randomized, double-blind, placebo-controlled trial enrolled 104 adults who met the Rome IV criteria for functional constipation. Participants received either Lactiplantibacillus plantarum Probio87 or placebo for 8\u202fweeks, followed by a 4-week post-intervention follow-up. The primary endpoint was weekly complete spontaneous bowel movements. Secondary outcomes included Rome IV symptom scores, PAC-QOL, HAMD-24, safety parameters, and exploratory whole-blood gene-expression profiles related to inflammation, immune regulation, neuroendocrine signaling, and gut motility. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR2300075360). Probio87 supplementation significantly increased weekly complete spontaneous bowel movements compared with placebo at Week 8 and Week 12. Improvements were also observed in Rome IV symptom scores, constipation-related quality of life, and HAMD-24 domains related to anxiety, sleep, and retardation. Exploratory whole-blood gene-expression analysis showed differential host-response signals after intervention, characterized by increased BDNF expression and reduced expression of IL-1\u03b2, CD117, CXCR5, IDO1, DBH, and MLNR in the probiotic group relative to placebo. No intervention-related adverse events or clinically relevant abnormalities in hematological, hepatic, or renal safety parameters were observed. L. plantarum Probio87 supplementation was associated with sustained improvement in bowel function, constipation-related quality of life, and psychological well-being in adults with functional constipation. Exploratory peripheral gene-expression findings suggest that inflammatory, immune, neuroendocrine, and motility-related host-response pathways may be involved, although causal mechanisms require further validation. https://www.chictr.org.cn/showproj.html?proj=205514, identifier (ChiCTR2300075360).",

PPE2-peptide treatment attenuated the induction of pro-inflammatory cytokines, enhanced the mRNA levels of tight junction proteins (Occludin, Claudin-1, and ZO-1), and prevented gut barrier function. PPE2 acts mainly by targeting the mast cells, as adoptive transfer of mast cells restored the symptoms of DSS-induced colitis in PPE2-treated mice. We further explored the development of a combination therapy aimed at targeting multiple pathways involved in inflammatory bowel disease (IBD) pathogenesis and showed that combination therapy of PPE2-peptide and mesalazine had better efficacy in improving UC symptoms. This study highlights a potential therapeutic strategy targeting fibroblast-mast cell crosstalk in IBD.",

Recent research reveals that ultrasound-based biophysical stimulation may change tumor microenvironmental variables that affect lactate metabolism and subsequent lactylation processes. The purpose of this study was to better understand the predictive significance of lactylation-associated genes in lung adenocarcinoma (LUAD) and how they could interact with ultrasound-mediated treatment response. Transcriptomic data from 867 LUAD samples were used to identify lactylation-related genes. Consensus clustering was used to separate LUAD cases into various lactylation subtypes. Differentially expressed genes were assessed for functional enrichment, mutation load, and immunological infiltration. A prognostic risk model was created using multivariate Cox regression analysis. Nineteen major lactylation-related genes divided patients with LUAD into three molecular subgroups with different clinical outcomes. A 10-gene prognostic model accurately predicted overall survival and was associated with stronger tumor stemness, increased mutational frequency, and decreased immunotherapy effectiveness in high-risk patients. Notably, computational predictions suggested that metabolic regulation might slow lactylation-driven tumor development, implying a synergistic treatment window. Lactylation-associated gene profiles may serve as prognostic biomarkers and therapeutic modulators in LUAD. The combination of ultrasound-based therapies targeting lactylation pathways could be a viable technique for improving precision oncology and overcoming resistance mechanisms in lung cancer therapy.",

However, its function in endothelial cells and its role in mediating postnatal angiogenesis remain unclear. The purpose of this study is to define the role of endothelial RGS5 in regulating VEGF signaling and angiogenesis. In a hindlimb ischemia model, we found impaired postnatal angiogenesis, reduced perfusion recovery, and increased rates of auto-amputation in mice with either global or endothelial-specific deletion of Rgs5. Rgs5 deficiency in ECs led to reduced VEGFR2 phosphorylation at Tyr1175 and its downstream signaling pathways. This was accompanied by increased activity of the tyrosine phosphatase, SHP-1, which dephosphorylates and inactivates VEGFR2. In vitro, Rgs5-deficient ECs exhibited diminished migration, increased apoptosis, and reduced viability in response to VEGF stimulation. These findings indicate that RGS5 is essential for maintaining VEGF-mediated angiogenic signaling through inhibition of SHP-1 activity. Endothelial RGS5 is a critical regulator of VEGF signaling and postnatal angiogenesis. By attenuating SHP-1-mediated dephosphorylation of VEGFR2, RGS5 preserves VEGF signaling and angiogenesis. Targeting the RGS5-SHP-1 axis may be a useful therapeutic strategy for improving angiogenesis in response to ischemia.",

Aging contributes not only to the increased incidence of these disorders but also to their progression through interconnected mechanisms, including endothelial dysfunction, oxidative stress, chronic inflammation, mitochondrial dysfunction, cellular senescence, metabolic imbalance, and gut microbiota dysbiosis. These processes collectively impair neuronal survival, synaptic plasticity, and cognitive and motor functions. Traditional Chinese medicine (TCM), with its characteristic multi-component and multi-target therapeutic strategies, has emerged as a promising approach to counteract age-associated neurological decline. Accumulating preclinical studies suggest that TCM interventions may exert neuroprotective, anti-inflammatory, and antioxidant effects, modulate autophagy, restore metabolic homeostasis, and potentially delay cellular senescence.

The p53-R280K mutation drives aggressive cancer, yet its role in fatty acid synthesis remains unclear. The CRISPR/CasRx technique was applied to knockdown endogenous mutant p53-R280K in MDA-MB-231 cells and wild-type p53 (WT-p53) in ZR75-1 cells. Luciferase reporter and ChIP assays demonstrated mutant p53-R280K binding to the FASN promoter and regulating its activity. Oil red O staining, flow cytometry, and triglyceride assays were used to determine the levels of lipid synthesis. Cell proliferation, wound healing and cell invasion assays were performed to detect the malignant phenotypes in vitro. Subcutaneous tumorigenesis and lung metastasis models of nude mice were established to validate tumor growth and metastasis in vivo. In this study, we reveal that p53-R280K hijacks the lipogenic transcription factor SREBP1 to form a transcriptional co-activation complex. This complex binds to and activates the fatty acid synthase (FASN) promoter, upregulating FASN expression. Enhanced FASN activity fuels de novo fatty acid synthesis, increasing lipid accumulation in breast cancer cells. Crucially, p53-R280K promotes cell proliferation, migration, and invasion in vitro, and drives tumor growth and lung metastasis in vivo in a FASN-dependent manner, as genetic or pharmacological inhibition of FASN abolishes these oncogenic effects. These findings establish that p53-R280K acquires a gain-of-function by co-opting SREBP1 to activate FASN transcription, reprogramming lipid metabolism to fuel breast cancer progression. Targeting the p53-R280K/SREBP1/FASN axis presents a promising therapeutic strategy for cancers harboring this specific p53 mutation.",

Resveratrol (RSV) is a polyphenol with antioxidant and anti-inflammatory properties, but its poor bioavailability limits therapeutic use. This study investigated whether PEGylated liposomes encapsulating RSV (LipRSV) could modulate oxidative and behavioral alterations in a valproic acid (VPA)-induced rat model of ASD.\u00a0PEGylated LipRSV were synthesized, characterized as hemocompatible, and administered to offspring from postnatal day (PND) 6 to 27. Behavioral tests included developmental milestones, olfactory discrimination, negative geotaxis, open field, and three-chamber social interaction. Oxidative stress markers and neurotrophins (BDNF, NGF) were quantified in the following brain regions: hippocampus, hypothalamus, striatum, cerebellum, frontal and posterior cortex.\u00a0LipRSV exerted limited and region-dependent redox effects, reducing ROS levels only in the hippocampus, cerebellum, and posterior cortex, while failing to improve behavioral outcomes and being associated with unfavorable neurochemical alterations, including reduced BDNF and NGF levels. Importantly, LipRSV also induced behavioral deficits, redox imbalance, and neurochemical alterations in control animals, indicating treatment-related effects in the absence of VPA exposure.\u00a0LipRSV modulated oxidative stress in a region-dependent manner without improving behavioral deficits in the VPA model and was associated with reduced BDNF and NGF levels. This study provides evidence that modulation of oxidative stress alone is insufficient to rescue behavioral phenotypes in the VPA model of ASD. These findings highlight the partial neurochemical efficacy and translational limitations of this formulation, suggesting the need for optimized nanocarrier design and dosing strategies in ASD pharmacotherapy.",

While serotonin (5-HT) promotes fibrogenesis via the 5-HT2B receptor, pharmacological interventions targeting this specific pathway remain scarce. Using a spectrum-effect approach, we screened bioactive phenolic acids from Rosa roxburghii Tratt extracts in a TGF-\u03b21-induced A549 cell model. Evaluating ellagic acid (EA), syringic acid (SA), and gallic acid (GA) both individually and in combination revealed that the EA/GA pairing (EG) yielded the most robust anti-fibrotic activity. Specifically, EG restored E-cadherin expression while suppressing key mesenchymal markers, effectively blunting epithelial-mesenchymal transition (EMT) in vitro. At the signaling level, EG treatment correlated with a downregulation of 5-HT2B-associated pathways, alongside marked reductions in oxidative stress and calcium influx. Our data suggest that EG dampens the Gq-PLC\u03b2-IP3R module, limiting both intracellular calcium mobilization and subsequent NFATc1 activation. Concurrently, we observed a suppression of the CaMKII-dependent NF-\u03baB cascade and its downstream pro-inflammatory targets (TNF-\u03b1, IL-6, and COX-2). These findings indicate that the EG combination alleviates pro-fibrotic responses in A549 cells by disrupting the 5-HT2B/calcium/inflammation axis. Although in vivo validation is required, this plant-derived combination offers a promising multi-targeted therapeutic strategy against pulmonary fibrosis.",

Increasing evidence indicates that alterations in gut microbial communities are associated with a wide range of neurological disorders; however, the strength of this association varies across diseases, and many mechanistic observations still rely predominantly on experimental models rather than human studies. This review provides an overview of current evidence regarding the role of the gut microbiota in maintaining CNS homeostasis, with particular emphasis on intestinal barrier function, immune modulation, vagal and enteric communication, and the generation of biologically active microbial metabolites, including short-chain fatty acids, bile acids, and neurotransmitter-related compounds. Studies in both clinical and experimental settings have reported disease-specific microbial signatures in conditions such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, autism spectrum disorders, and amyotrophic lateral sclerosis. In parallel, microbiota-directed interventions-including probiotics, prebiotics, dietary approaches, fecal microbiota transplantation, and strategies targeting microbial metabolites-have produced encouraging findings in preclinical studies and early-stage clinical investigations. Nevertheless, considerable heterogeneity in study populations, experimental methodologies, and therapeutic protocols continues to limit the translation of these findings into routine clinical practice. Collectively, current evidence supports the MGBA as a valuable framework for understanding neurological diseases while underscoring the need for rigorously designed longitudinal studies and well-controlled clinical trials to define its therapeutic relevance better.",

Emerging evidence implicates the gut-brain axis in neurological disorders, but its role in central fatigue remains unexplored. This study aimed to elucidate the gut-brain axis in central fatigue via multi-omics and identify potential therapeutic targets. We employed a multi-omics approach in a validated rat model of central fatigue, integrating 16S rRNA sequencing of gut microbiota, untargeted serum metabolomics, and hippocampal transcriptomics. Behavioral tests and fatigue-related biochemical indicators confirmed the central fatigue phenotype. Network analysis connected microbial and metabolic changes. The key findings from the multi-omics analysis were validated through assessments of mitochondrial structure and function, along with molecular expression analyses. Central fatigue was associated with significant gut microbiota dysbiosis and altered serum metabolites, notably an alteration in peripheral arachidonic acid. Multi-omics integration identified a core \"Bacteroides-arachidonic acid\" axis. Hippocampal transcriptomics revealed enrichment in ferroptosis and oxidative phosphorylation pathways. Subsequent validation demonstrated that arachidonic acid activates the ACSL4-ALOX15 pathway, resulting in elevated 15-HETE and ROS levels, along with Fe2+ accumulation, GPX4 downregulation, transferrin upregulation, and mitochondrial dysfunction, which collectively may contribute to hippocampal ferroptosis. Conversely, treatment with the ferroptosis inhibitor ferrostatin-1 significantly restored hippocampal mitochondrial function and ameliorated key behavioral manifestations of central fatigue. This study delineates a novel gut-brain pathway in central fatigue, where microbiota-associated arachidonic acid metabolic alterations are associated with hippocampal ferroptosis, potentially involving the ACSL4-ALOX15-GPX4 pathway. These findings provide new mechanistic insights and therapeutic targets for central fatigue.",

Conventional antiepileptic drugs (AEDs) are constrained by two interrelated barriers: limited brain penetration due to the blood-brain barrier (BBB), which necessitates high systemic dosing and peripheral toxicity, and a narrow mechanistic focus on neuronal ion channels and synaptic receptors. This neuron-centric view overlooks non-neuronal drivers, such as neuroinflammation and BBB dysfunction, that sustain epileptogenesis and contribute to drug resistance in roughly one-third of patients. Nanomedicine addresses these limitations through a fundamentally different approach. Leveraging the unique advantages of nanocarriers, including facile synthesis, surface modification, and receptor-mediated BBB transcytosis, nanoparticles have evolved from passive delivery vehicles into intelligent, multifunctional therapeutic platforms that actively engage with disease biology. In this Perspective, we first delineate the inherent limitations of conventional AEDs in target selection. We then highlight how emerging nanomedicines are expanding the therapeutic target repertoire to include key non-neuronal nodes, with a focus on neuroinflammation and BBB repair. Finally, we offer a forward-looking perspective on two emerging frontiers: modulation of metabolic dysregulation and the microbiota-gut-brain axis, as well as the development of theranostic nanoplatforms that integrate real-time seizure monitoring with closed-loop intervention. Through this discussion, we aim to inspire a reorientation of nanomedicine strategies toward precision therapy for epilepsy.",

Increasing evidence suggests that gut microbiota disturbances contribute to AD progression, encouraging the investigation of microbiota-modulating approaches such as probiotics and paraprobiotics.

From day 4, animals received daily oral treatment with probiotic L. casei (1\u202f\u00d7\u202f109\u202fCFU), paraprobiotic (100\u202fmg/kg), or saline for 14\u202fdays. Behavioral assessments of memory and exploratory activity were performed alongside biochemical analyses of oxidative stress markers, antioxidant defenses, acetylcholinesterase (AChE) activity, and neuroinflammatory parameters in central and peripheral tissues. STZ-ICV administration induced impairments in working and long-term memory, increased oxidative stress and neuroinflammation, elevated AChE activity, and promoted intestinal and behavioral alterations. Both probiotic and paraprobiotic treatments attenuated memory deficits, reduced lipid peroxidation, inhibited AChE activity, and decreased inflammatory markers. However, their effects differed in magnitude and tissue specificity. The probiotic mainly improved peripheral antioxidant defenses, whereas the paraprobiotic exerted broader neuroprotective effects, reducing cerebral oxidative stress, restoring non-enzymatic antioxidant levels in the hippocampus and colon, improving jejunal catalase activity, and attenuating hippocampal astrogliosis. These findings demonstrate that modulation of the gut-brain axis through L. casei-based interventions mitigates key pathological features of sporadic AD, with paraprobiotics emerging as a promising and stable alternative with enhanced neuroprotective potential independent of bacterial viability.",

Increasing evidence supports the view of HFpEF as a systemic inflammatory syndrome driven by aging and cardiometabolic comorbidities, including obesity, hypertension, and chronic kidney disease. Within this framework, regulatory T cells (Tregs), which are essential for maintaining immune tolerance and limiting excessive inflammation, have emerged as important modulators of disease progression. However, the mechanisms underlying Treg dysfunction in HFpEF have remained poorly understood. In this issue, Srinivas et al. identify stromal interaction molecule 1 (STIM1)-dependent calcium signaling as a critical regulator of Treg instability in HFpEF. The authors show that patients with HFpEF exhibit reduced circulating Treg numbers, increased STIM1 expression, and activation of endoplasmic reticulum stress, apoptotic, and inflammatory pathways. Using a cardiometabolic murine model and Treg-specific STIM1 knockout mice, they establish a causal role for Treg-intrinsic STIM1 signaling in disease development. These findings position STIM1 as a molecular link between cardiometabolic stress, immune dysregulation, and cardiac remodeling. They further support the concept that immune-cell plasticity is a major determinant of HFpEF pathogenesis and suggest that preserving Treg stability may represent a novel therapeutic strategy. Although important questions remain regarding disease timing, clinical translation, and sex-specific effects, this work advances our understanding of HFpEF as an immune-mediated disorder and identifies STIM1-dependent calcium signaling as a promising therapeutic target.",

The amount of albumin excreted in the urine is an independent predictor of declining kidney function, cardiovascular events, and all-cause mortality. It is most easily determined based on the albumin-to-creatinine ratio (ACR) measured in the first morning urine sample; in the vast majority of cases, 24-hour urine collection is not required. The pathophysiology of albuminuria centers on damage to the glomerular filtration barrier - particularly podocytes - hemodynamic hyperfiltration, inflammation associated with tubular protein reabsorption, and activation of the renin-angiotensin-aldosterone system (RAAS). Modern four-pillar pharmacotherapy - RAS inhibitors (ACE inhibitors/ARBs), SGLT2 inhibitors, non-steroidal mineralocorticoid receptor antagonists (finerenone), and GLP1 receptor agonists in type 2 diabetes - acts on these processes through complementary mechanisms. When tailored to the degree of albuminuria and eGFR, this treatment significantly slows the progression of chronic kidney disease and reduces cardiovascular risk. Measuring and monitoring albuminuria must therefore be an essential part of daily clinical practice. Orv Hetil. 2026; 167(31): 1231-1237.

However, its function often exhibits contradictory effects: In renal fibrosis, ALKBH5 has been reported to both promote and suppress fibrogenesis, whereas in renal cell carcinoma most studies support an oncogenic role, but some clinical observations link ALKBH5 downregulation to poor prognosis. These contradictions may stem from differences in cell types, disease stages, and microenvironments. This manuscript systematically reviews the complex function of ALKBH5 in kidney diseases and its underlying mechanisms, explores its potential as a therapeutic target, evaluates its therapeutic potential, and highlights the need for cell- and pathology-specific strategies to enable precise intervention.

Ensiled With Molasses by Bioactive Agents: Effects on Ensiling Characteristics, Aerobic Stability, Rumen Fermentation, and Characteristics In\u00a0Vitro.\nAbstract: This study investigated the effects of plant-derived bioactive compounds on the fermentation characteristics and aerobic stability of berseem (Trifolium alexandrinum) silage and evaluated their impact on ruminal fermentation. In Experiment 1, curcumin, resveratrol, eugenol, limonene, and thymol were applied at 400 and 800\u2009mg/kg fresh matter in combination with molasses (50\u2009g/kg) and ensiled for 60\u2009days to screen their effects on silage quality. Bioactive supplementation modified fermentation in a compound- and dose-dependent manner, reflecting differences in physicochemical properties and antimicrobial selectivity. Among the tested compounds, eugenol was the most effective in enhancing silage fermentation and aerobic stability, as it reduced pH, increased lactic acid concentration (p\u2009<\u20090.05), and maintained Flieg's score comparable to the control. Experiment 2 evaluated the ruminal consequences of eugenol-treated silage using in\u00a0vitro incubation at 24 and 48\u2009h. Eugenol supplementation reduced nutrient degradability and microbial protein synthesis at 48\u2009h and decreased methane production at both incubation times (p\u2009<\u20090.05). Overall, eugenol showed promising effects for improving silage preservation and aerobic stability; however, it reduced in\u00a0vitro nutrient degradability and microbial protein synthesis, suggesting that optimization of inclusion strategies is required to minimize potential negative effects on ruminal nutrient utilization.",

Fresh mulberry juice was used as the raw material and inoculated with P. acidilactici strain 003W to establish a fermentation system. After fermentation at 37 \u2103 for 48 h, the active components (total phenolics and anthocyanins), physicochemical indexes (pH, total acid content, reducing sugar content), antioxidant activity (DPPH and ABTS+ radical scavenging rates), and electronic tongue flavor characteristics (sourness, astringency, richness, etc. ) were evaluated before and after fermentation. The result showed that after fermentation, the total phenolic content increased from 11.01 mg GAE/mL to 13.41 mg GAE/mL, and the anthocyanin content increased from 0.60 mg RE/mL to 0.79 mg RE/mL. The pH value decreased from 5.70 to 4.34; the total acid content (expressed as lactic acid) increased from 4.10 g/L to 12.24 g/L; and the reducing sugar content (expressed as glucose) decreased from 85.00 mg/mL to 75.00 mg/mL. The DPPH free radical scavenging rate and ABTS+ free radical scavenging rate reached 40.08% and 49.87% from 18.00% and 28.00%(P<0.05). Electronic tongue analysis indicated that the sourness and richness of fermented mulberry juice were enhanced, while the astringency was significantly reduced, resulting in a more harmonious flavor profile. This study demonstrates that fermentation by P. acidilactici 003W effectively enhances the content of active components, antioxidant capacity, and flavor characteristics of mulberry juice, offering a scientific foundation for developing high-value probiotic mulberry beverages.",
"42543261": "ID: 42543261\nTitle: BCL9 inhibition promotes fibroblast lipogenesis by regulating macrophage-fibroblast interactions to attenuate pulmonary fibrosis.\nAbstract: Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease with an urgent need for novel therapeutic strategies. M2 macrophage-derived TGF-\u03b21 promotes fibroblast myogenesis, contributing to IPF pathogenesis. Targeting macrophage polarization and fibroblast function thus represents an effective therapeutic approach for treating IPF. Here, we identify B-cell lymphoma 9 (BCL9) as a key upstream regulator implicated in IPF pathogenesis. We demonstrate that BCL9 drives the macrophage M2 program through the MerTK-ERK-SPP1 axis. Notably, pharmacological inhibition of BCL9 with our novel peptide, hsBCL9Z96, effectively attenuates pulmonary fibrosis by reprogramming macrophage-fibroblast crosstalk. Specifically, BCL9 inhibition promotes fibroblast lipogenesis via TGF-\u03b21 signaling, which in turn supports alveolar type 2 (AT2) cell expansion. This macrophage-orchestrated fibroblast phenotypic switch from myogenic to lipogenic is visually corroborated by spatial transcriptomic analyses and immunofluorescence staining of human lung tissues. Functionally, the pathological role of BCL9 and efficacy of hsBCL9Z96 are validated in human cellular models, including IPF patient-derived cells, confirming its translational significance. Collectively, our findings not only elucidate a novel BCL9-driven macrophage-fibroblast-AT2 cell axis in IPF but also establish hsBCL9Z96 as a promising first-in-class therapeutic candidate, providing a strong rationale for targeting BCL9-mediated Wnt signaling in clinical IPF treatment.",

A total of 24 male SD rats were randomly divided into four groups: a control group, a model group, a positive control group and an Mxd treatment group, with 6 rats in each group. After 5 days of quarantine and adaptive feeding, the IPF pathological model was induced by intratracheal instillation of bleomycin under laryngoscopic assistance in the model group, positive control group, and Mxd treatment group. Gastric gavage was initiated after successful modeling, and all SD rats were sacrificed on the 15th day post gavage. HE staining and Masson staining were used to observe histopathological changes of lung tissue, while HE staining was adopted to evaluate jejunal pathological changes. Enzyme-linked immunosorbent assay(ELISA) was performed to detect the serum levels of interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6), and tumor necrosis factor-\u03b1(TNF-\u03b1) in rats. AB-PAS staining was employed to determine the number of goblet cells in jejunal mucosal tissue. Immunofluorescence assay was used to detect the expression of zonula occludens-1(ZO-1) and occludin in rat jejunum, and 16S rDNA sequencing was conducted to analyze the intestinal microbiome of all rats. The results showed that the model group exhibited severe damage to jejunal mucosa and lung tissue accompanied by massive inflammatory cell infiltration, while the two treatment groups demonstrated partial structural defects with a small amount of inflammatory cell infiltration in the lungs and jejuna of rats. Compared with the control group, the model group showed significantly decreased body weight, number of goblet cells, and expression of ZO-1 and occludin proteins(P<0.01), while these indicators were notably increased after intervention in the two treatment groups(P<0.05 or P<0.01). According to 16S rDNA sequencing results, Mxd could regulate the richness and diversity of intestinal flora in rats. KEGG pathway analysis indicated that Mxd regulated pathways such as oxidative phosphorylation, amino sugar, and nucleotide sugar metabolism of intestinal flora in rats. In conclusion, the alteration of intestinal microbiome may be one of the potential mechanisms underlying the therapeutic effect of Mxd on IPF. Mxd can regulate the structure of intestinal microbiome, increase the abundance of beneficial bacteria, and reduce the number of harmful bacteria, as well as protect intestinal barrier and inhibit inflammatory response.",

Mouse models of pneumonia induced by intranasal influenza A virus(H1N1) infection and intratracheal lipopolysaccharide(LPS) instillation were established. The effects of the water extract of SR on pulmonary CT imaging, histological damage, and inflammatory cytokine expression in lung tissues were evaluated. Using bone marrow-derived macrophages, this study analyzed the regulatory effects of the extract on macrophage proliferation and phagocytic function. RNA-seq and bioinformatics analysis, combined with molecular biology experiments, were employed to explore the regulatory role of the water extract of SR on the type \u2160 interferon(IFN-\u2160) signaling pathway. The findings revealed that the water extract of SR significantly alleviated H1N1 infection-induced lung imaging and pathological damage in mice, reduced lung viral gene copies, and downregulated the expression of inflammatory cytokines such as interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), and CXC motif chemokine ligand 10(CXCL10). Concurrently, drug treatment demonstrated similar lung tissue protective functions in the LPS-induced mouse pneumonia model. Cell experiments showed that the extract promoted proliferation of macrophages and enhanced their phagocytic capacity toward neutral red. Transcriptomic analysis revealed that genes upregulated by the extract of SR were significantly enriched in pathways including H1N1 infection, Toll-like receptor signaling, NOD-like receptor signaling, and IFN signaling. Finally, qRT-PCR and Western blot confirmed that the extract activated the interferon signaling pathway. In conclusion, the extract of SR activates innate immunity centered on IFN-\u2160 signaling and enhances macrophage function, thereby improving the host's defense against viral and bacterial infections. It possesses potential preventive and therapeutic value for respiratory tract infection-associated pneumonia and lung injury.",

In vivo, an ALI model was established using SD rats by intraperitoneal injection of LPS(5 mg\u00b7kg~(-1)). The animals were randomly divided into six groups: control group, model group, dexamethasone(DEX, 0.315 mg\u00b7kg~(-1)) group, and low-, medium-, and high-dose JSD groups(0.787 5, 1.575, and 3.15 g\u00b7kg~(-1), respectively). Wet/dry weight ratio(W/D), myeloperoxidase(MPO) activity, superoxide dismutase(SOD) activity in lung tissues, and nitric oxide(NO) levels in serum were measured. Pathological changes in lung tissue were observed by hematoxylin-eosin(HE) staining, and the percentage of alveolar area(PAA) was scored. Enzyme-linked immunosorbent assay(ELISA) and real-time quantitative polymerase chain reaction(RT-qPCR) were used to detect the content and mRNA expression of tumor necrosis factor(TNF)-\u03b1 and interleukin(IL)-1\u03b2 in serum and lung tissues. Immunohistochemistry and Western blot were employed to analyze the protein expression of Toll-like receptor 4(TLR4) and matrix metalloproteinase 9(MMP9), as well as the phosphorylation levels of inhibitor of nuclear factor-\u03baB(I\u03baB), p65, p38, and extracellular signal-regulated kinase(ERK). In vitro, A549 cells were stimulated with LPS(20 \u03bcg\u00b7mL~(-1)) to establish an inflammation model and treated with JSD-containing serum. Cell viability was assessed by MTT assay. The mRNA expression of TNF-\u03b1, IL-1\u03b2, IL-6, IL-18, TLR4, myeloid differentiation factor 88(MyD88), MMP9, CXC chemokine ligand 2(CXCL2), and IL-10 was detected by RT-qPCR. Western blot was used to evaluate the phosphorylation of I\u03baB, p65, p38, and ERK. The results showed that JSD significantly reduced the lung W/D ratio and alleviated pulmonary edema. It inhibited MPO activity and NO levels and enhanced SOD activity, which indicated the mitigation of oxidative stress. HE staining showed that it significantly ameliorated LPS-induced pathological changes, including alveolar structural destruction and inflammatory cell infiltration, and increased the PAA score. ELISA and RT-qPCR indicated that JSD decreased the levels and mRNA expression of pro-inflammatory cytokines such as TNF-\u03b1 and IL-1\u03b2. Immunohistochemistry and Western blot revealed that JSD suppressed the protein expression of TLR4 and MMP9 and downregulated the phosphorylation of I\u03baB, p65, p38 and ERK. In vitro, JSD-containing serum had no significant effect on cell viability but significantly reduced the mRNA expression of inflammatory factors(TNF-\u03b1, IL-1\u03b2, IL-6, IL-18, TLR4, MyD88, MMP9, and CXCL2) and increased the expression of the anti-inflammatory factor(IL-10). It also downregulated the phosphorylation of I\u03baB, p65, p38 and ERK. In conclusion, JSD alleviates LPS-induced ALI by regulating the TLR4/MAPK/NF-\u03baB signaling pathway and thereby suppressing inflammatory response and oxidative stress.",

HPLC was used to establish fingerprints of fifteen batches of C. militaris, and chemometric analysis was performed to preliminarily screen out differential components. A "component-target-pathway" network was constructed utilizing network pharmacology to further predict quality markers of C. militaris in improvement of respiratory diseases. The inflammatory model of the BEAS-2B cell was induced by lipopolysaccharide, and the levels of inflammatory factors interleukin(IL)-6, IL-1\u03b2, and tumor necrosis factor(TNF)-\u03b1 were detected by quantitative real-time polymerase chain reaction(PCR) to verify the activity of quality markers. Their content was determined by HPLC. In the fingerprints of the fifteen batches of C. militaris, eight common peaks were calibrated, and five main components were identified with similarities between 0.893 and 0.996. Five differential compounds were preliminarily screened through chemometric analysis. Seven efficacy related ingredients were predicted by network pharmacology. Based on the "five principles" characteristics of TCM quality markers, four functional components, namely uridine, guanosine, adenosine, and cordycepin, were ultimately selected as quality markers of C. militaris for improving respiratory diseases. Furthermore, the quality markers were found to significantly inhibit the expression of IL-6, IL-1\u03b2, and TNF-\u03b1, exerting anti-inflammatory effects in in vitro experiments. Their average content was 0.198%, 0.142%, 0.258%, and 0.116%, respectively.

The GEO dataset GSE183077 was used for bioinformatics analysis to identify differentially expressed genes(DEGs) of M1 and M0 macrophages, which was followed by Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses. The M1 macrophage model was established in RAW264.7 macrophages by stimulation with LPS and IFN-\u03b3. Cell counting kit-8(CCK-8) assays were used to evaluate cell viability and determine the optimal concentration of harpagide for treatment. The Griess assay was performed to measure nitric oxide(NO) levels. The mRNA expression levels of interleukin-6(IL-6), interleukin-1\u03b2(IL-1\u03b2), and tumor necrosis factor-\u03b1(TNF-\u03b1) were determined by real-time quantitative polymerase chain reaction(qRT-PCR). JC-1, Mito-Tracker, and Mito-SOX fluorescent probes were used to assess mitochondrial membrane potential, mitochondrial function, and mitochondrial reactive oxygen species(ROS) levels, respectively. Western blot analysis was conducted to detect the protein expression levels of PGC-1\u03b1, NOD-like receptor family pyrin domain containing 3(NLRP3), dynamin-related protein 1(DRP1), inducible nitric oxide synthase(iNOS), and TNF-\u03b1. Transcriptomic analysis revealed that inflammatory responses and mitochondrial fission-related biological processes were significantly activated during M1 macrophage polarization. In vitro experiments confirmed that, compared with the control group, the model group exhibited an increased NO level in cell culture supernatant, elevated mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, impaired mitochondrial function, decreased mitochondrial membrane potential, and elevated mitochondrial ROS levels. Meanwhile, PGC-1\u03b1 protein expression was reduced, whereas NLRP3, DRP1, iNOS, and TNF-\u03b1 protein levels were upregulated. Following harpagide treatment, these changes were reversed in a dose-dependent manner, namely decreased NO production and mRNA expression of IL-6, IL-1\u03b2, and TNF-\u03b1, improved mitochondrial function, restored mitochondrial membrane potential and mitochondrial ROS levels, significantly upregulated PGC-1\u03b1 expression, and decreased expression of NLRP3, DRP1, iNOS, and TNF-\u03b1. In conclusion, harpagide alleviates inflammatory responses probably by modulating mitochondrial fission in macrophages and inhibiting NLRP3 inflammasome activation via activating PGC-1\u03b1.",

The mice were randomly divided into a control group, model group, low-dose HCFs group, middle-dose HCFs group, high-dose HCFs group, and fluoxetine group. After four consecutive weeks of gastric gavage administration, the sucrose preference test, forced swimming test, tail suspension test, and open-field test were conducted to evaluate depression-like behaviors. The levels of corticosterone(CORT), interleukin-6(IL-6), tumor necrosis factor-\u03b1(TNF-\u03b1), hippocampal 5-hydroxytryptamine(5-HT), and brain-derived neurotrophic factor(BDNF) in the serum were determined by enzyme-linked immunosorbent assay; hematoxylin-eosin staining was used to observe hippocampal pathological changes; transcriptome sequencing was performed to analyze differentially expressed genes and Western blot was performed to detect the expression levels of key proteins related to the neuronal function and inflammatory response. The results demonstrate that compared with the model group, HCFs groups with low, medium, and high doses can significantly increase sucrose preference, decrease immobility time, enhance central zone activity, reduce CORT, IL-6, and TNF-\u03b1 levels, elevate BDNF and 5-HT contents, and alleviate hippocampal tissue injury. Transcriptomics and Western blot analyses reveal that HCFs can significantly up-regulate the pathways related to neurotransmitter synthesis, myelin formation, synaptic plasticity, and energy metabolism regulation, while down-regulating the pathways related to inflammatory response and excessive metabolism and regulating the expressions of proteins related to hippocampal neuronal function and inflammatory response. In conclusion, HCFs exert a significant antidepressant effect on CUMS-induced mice, and their mechanism may be related to the multi-target synergistic regulation involving monoamine neurotransmitter balance and neuroinflammation inhibition.",

However, the systemic pathological network underlying sarcopenia secondary to CHF remains unclear. This review constructed a multi-level mechanistic framework. Starting from the macroscopic hemodynamic disorders and neuroendocrine activation caused by CHF, the review proceeded to explain how they lead to mesoscopic multi-organ crosstalk dysfunction(including intestinal barrier damage/elevated trimethylamine N-oxide, impaired hepatic synthesis, pulmonary edema, and renal water-sodium retention). These alterations collectively created a systemic milieu characterized by chronic inflammation, oxidative stress, and insulin resistance. This milieu, in turn, triggered a series of microscopic lesions in skeletal muscle, encompassing metabolic imbalance of protein, neuromuscular junction degeneration, microcirculatory disturbances, and myokine secretion dysregulation, all of which ultimately converged, via mitochondrial dysfunction, on a common terminal pathway called "energy metabolism collapse." This review further interpreted this process through the lens of TCM theory, attributing it to a systemic dysfunction rooted in the progression from "Qi deficiency in heart" to "Yang deficiency in heart". This deficiency led to "Yang Qi counterflow" and "three energizer blockage", and the ensuing "internal toxin" and "sthenic fire", corresponding to the states of chronic inflammation and oxidative stress in modern medicine. The multi-level mechanistic framework proposed herein not only elucidates the active role of skeletal muscle via the "muscle-heart axis" but also thereby lays a theoretical foundation for future therapeutic strategies based on multi-target regulation and the integration of TCM and western medicine.",

The optimal preparation process of HPSCH was investigated by using schisandrin content and total extractive yield as indices. After one week of adaptive feeding, C57BL/6 mice were assigned to a normal control group, while the remaining mice were fed an HFD for eight weeks to establish the NAFLD mouse model. After being successfully modeled, the mice were divided into a blank control group, blank administration group, simple model group, fenofibrate group, SCH group, and HPSCH group. All groups were administered by intragastric administration for four weeks. Body weight changes of mice were recorded, and liver indices were calculated. The levels of blood lipid and liver function index in the serum of mice were measured. Hepatic histopathological changes were observed by using hematoxylin-eosin(HE) staining and oil red O staining. Mice's feces were collected, and the 16S rDNA high-throughput sequencing method was employed to analyze changes in the gut microbiota of mice. Untargeted lipidomic analysis of the liver was conducted by using liquid chromatography-mass spectrometry(LC-MS), and principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were adopted to screen and identify differential metabolites. Kyoto Encyclopedia of Genes and Genomes(KEGG) database was used to perform relevant pathway analysis. Integrated analyses of gut microbiota and differential metabolites were performed to compare the similarities and differences in efficacy of HPSCH and SCH. The results show that both the HPSCH group and SCH group exert similar effects on biochemical indices in serum and hepatic pathological changes, lipid metabolism can be regulated, and liver injury in NAFLD mice can be improved. The two groups show similar changes in microbial abundance, trending toward the blank control group and maintaining intestinal homeostasis. Compared with those of the simple model group, the differential metabolites and metabolic pathways of both the HPSCH group and SCH group show similarity, and the differential metabolites are mainly triglycerides, diglycerides, phosphatidylcholines, phosphatidylglycerols, and so on. Metabolic pathways include glycerophospholipid metabolism, choline metabolism, retrograde endocannabinoid signaling, thermogenic lipolysis, and so on. This indicates that HPSCH and SCH share common advantages in improving hepatic function in mice and achieve comparable effects. HPSCH can improve blood lipid and liver function indices in NAFLD mice, attaining the therapeutic effect through the regulation of gut microbiota and lipid metabolism. Notably, HPSCH achieved the same efficacy as SCH at half the conventional dose, demonstrating its feasibility for clinical application. Moreover, the application of HPSCH may contribute to the conservation of medicinal resources.",

A total of 34 active ingredients of Scutellariae Radix were screened from the TCMSP database, and 65 potential therapeutic targets were identified by combining SwissTargetPrediction and GEO data analysis. Protein-protein interaction(PPI) network construction, molecular docking, and Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses indicated that Scutellariae Radix might exert the anti-AS effect by modulating inflammatory responses, negatively regulating pyroptosis, and influencing the NOD-like receptor(NLRP) signaling pathway. In vivo, AS was induced in ApoE~(-/-) mice by 16-week high-fat diet feeding, followed by intervention with Scutellariae Radix extract. The results showed that Scutellariae Radix significantly attenuated lipid deposition and plaque area in the aortic wall, decreased serum levels of total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG), and increased the high-density lipoprotein cholesterol(HDL-C) level, thereby improving lipid metabolism disorders. Meanwhile, it markedly inhibited the expression of proinflammatory cytokines tumor necrosis factor-\u03b1(TNF-\u03b1), interleukin(IL)-1\u03b2, and IL-6. In addition, Scutellariae Radix significantly suppressed nuclear factor-\u03baB(NF-\u03baB) phosphorylation and downregulated the protein expression of NOD-like receptor pyrin domain-containing protein 3(NLRP3), cleaved caspase-1, and the N-terminal fragment of gasdermin D(N-GSDMD), which suggested that Scutellariae Radix effectively inhibited pyroptosis in arterial tissues. Collectively, these findings suggested that Scutellariae Radix ameliorated AS by suppressing pyroptosis in arterial tissues, attenuating inflammation, and improving lipid metabolism via regulating the NLRP3/caspase-1/GSDMD signaling pathway.",
"42543326": "ID: 42543326\nTitle: [Research progress on action mechanisms of Rheum palmatum anthraquinones in improving acute lung injury].\nAbstract: Acute lung injury(ALI) and acute respiratory distress syndrome(ARDS) are severe respiratory diseases characterized by uncontrolled inflammatory responses and disruption of the alveolar-capillary barrier. This type of disease is often triggered by multiple factors such as infection, sepsis, trauma, or inhalation injury, and the pathological process involves multiple sections including inflammatory cascade reactions, oxidative stress imbalance, abnormal activation of immune cells, and increased pulmonary microvascular permeability. Owing to their complex pathogenesis and high mortality, available clinical therapeutic approaches remain limited. Therefore, the development of safe and effective therapeutic agents to attenuate ALI has become a major focus of current research field. As a TCM, Rheum palmatum has a long history of use in clearing heat and toxins, purging the bowels, and regulating systemic inflammatory responses. In recent years, increasing attention has been paid to its therapeutic effect in ALI. RESULTS:: show that R. palmatum and its major bioactive anthraquinones, such as emodin and rhein, exert protective effects through multi-target and multi-pathway mechanisms. These mechanisms mainly include inhibition of inflammatory signaling pathways such as nuclear factor-\u03baB(NF-\u03baB), mitogen-activated protein kinase(MAPK), and NOD-like receptor protein 3(NLRP3) inflammasome, attenuation of oxidative stress response, activation of the nuclear factor erythroid 2-related factor 2(Nrf2)-mediated antioxidant defense system, regulation of programmed death in immune cells including macrophages, improvement of immunometabolic status, modulation of macrophage polarization and the gut microbiota as well as the gut-lung axis, and so on. In addition, R. palmatum has been shown to preserve the integrity of the alveolar-capillary barrier and to suppress excessive neutrophil activation and the overformation of neutrophil extracellular traps(NETs), thereby reducing inflammation amplification effect and the risk of immune microthrombi. This paper summarized the action mechanisms and research progress of R. palmatum in the treatment of ALI, aiming to elucidate the unique advantages of R. palmatum anthraquinones in intervening in the complex pathological processes of ALI through systemic regulatory networks and to provide a solid theoretical basis for the research and development of innovative R. palmatum-based medicines and their clinical combination medication.",
"42543327": "ID: 42543327\nTitle: [Research progress on mechanisms and therapeutic potential of active components of TCM in intervening lipid metabolism reprogramming in colorectal cancer].\nAbstract: Lipid metabolism reprogramming is a hallmark metabolic feature in the pathogenesis and progression of colorectal cancer(CRC), primarily involved in the aberrant activation of de novo lipogenesis(DNL), disruption of cholesterol homeostasis, enhancement of fatty acid oxidation(FAO), and resistance to ferroptosis. All of these pathological processes mediate malignant progression and multidrug resistance of tumors. According to TCM, the pathological foundation of CRC lies in the interlocking of "dampness, heat, stasis, and deficiency", which exhibits an intrinsic biological consistency with ectopic lipid accumulation, metabolic pathway perturbations, and the imbalance of microenvironmental homeostasis. This article systematically reviewed the molecular regulatory networks of lipid metabolism reprogramming in CRC, emphasizing the molecular mechanisms by which active components of TCM intervene in lipid metabolism homeostasis by modulating core targets such as sterol regulatory element-binding proteins(SREBPs), glutathione peroxidase 4(GPX4), solute carrier family 7 member 11(SLC7A11), and carnitine palmitoyltransferase 1(CPT1). Pharmacological studies demonstrate that active ingredients, including berberine, tanshinone \u2161_A, ginsenosides, curcumin, and hesperetin, elucidate the molecular scientific connotations of therapeutic principles, such as "clearing heat, drying dampness, promoting blood circulation, removing toxic substances, strengthening body resistance to consolidate the constitution, and disinhibiting dampness to transform phlegm", by intervening in lipid synthesis, ferroptosis, energy metabolism, and inflammatory signaling pathways. Furthermore, the clinical application potential of active components of TCM in reversing chemotherapy resistance, synergizing with immunotherapy, and the chemoprevention of adenomas is systematically evaluated. By providing an in-depth analysis of the biological correlations between TCM syndrome theory and lipid metabolism regulation, this review aims to offer a pharmacological basis for the development of TCM candidates targeting metabolic remodeling and for the optimization of diagnostic and therapeutic protocols of integrated Chinese and western medicine.",
"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.",
"42543330": "ID: 42543330\nTitle: [Construction of a long-lived engineered yeast and its efficient catalytic synthesis of ursodeoxycholic acid].\nAbstract: Ursodeoxycholic acid(UDCA) is a first-line drug for the clinical treatment of hepatobiliary diseases. The bioconversion of chenodeoxycholic acid(CDCA) based on whole-cell catalysis provides an important alternative approach for its green production. However, during fermentation, cellular aging and CDCA-induced stress lead to decreased stability of the catalytic system, which severely restricts its industrial application. This study took the extension of cellular chronological lifespan as the entry point, and systematically evaluated the effects of overexpressing the chronological lifespan regulatory factor heme activator protein 4 gene(HAP4) on whole-cell catalytic performance. The results showed that, under CDCA stress conditions after 8 days of fermentation, the survival rate of cells overexpressing HAP4 was 4.5-fold higher than that of the wild type, indicating that HAP4 overexpression significantly prolonged the CLS of Saccharomyces cerevisiae. Furthermore, by screening efficient genetic elements, an efficient catalytic module was obtained, consisting of 7\u03b1-hydroxysteroid dehydrogenase(7\u03b1-HSDH) from Escherichia coli and RT-7\u03b2-hydroxysteroid dehydrogenase(RT-7\u03b2-HSDH) from Ruminococcus torques. These enzymes were assembled in S. cerevisiae BY4742 to construct an efficient CDCA whole-cell catalytic strain, BY-RT, which achieved a UDCA conversion rate of 96.0%. On this basis, HAP4 was further overexpressed to obtain a long-lived engineered strain, BY-RT-HAP4. After 20 days of shake-flask fermentation, the catalytic efficiency of BY-RT-HAP4 remained at 44.4%, representing a 14.8-fold increase compared with BY-RT. Finally, industrial fermentation conditions were simulated in a 5 L bioreactor to systematically evaluate the effect of enhanced HAP4 expression on UDCA whole-cell catalytic performance. Under conditions of greater environmental stress and higher substrate concentration stress, the catalytic efficiency of BY-RT-HAP4 at the end of fermentation was still 13.4% higher than that of BY-RT. These results demonstrate that enhanced HAP4 expression can effectively maintain cellular activity and metabolic homeostasis, significantly improve the whole-cell conversion efficiency of UDCA, and provide a new metabolic engineering strategy and theoretical basis for the green and efficient biosynthesis of UDCA.",

An oxidative injury model in MC3T3-E1 cells was established with 200 \u03bcmol\u00b7L~(-1) H_2O_2. The experiment was conducted with four groups: normal, model, psoralen, and inhibitor groups. Cell viability and proliferation were assessed by the CCK-8 assay and EdU incorporation assay, respectively. Apoptosis was analyzed by Annexin V-FITC/PI double-staining flow cytometry. Mitochondrial membrane potential was evaluated with the JC-1 probe, and reactive oxygen species(ROS) levels were measured by the DCFH-DA probe. Early osteogenic differentiation markers and late mineralized nodule formation were observed by alkaline phosphatase(ALP) staining and alizarin S staining, respectively. Transmission electron microscopy was employed to examine mitochondrial ultrastructure changes. Immunofluorescence staining and Western blot were employed to determine the expression levels of PINK1, Parkin, p62, Runt-related transcription factor 2(Runx2), and Osterix. Molecular docking and 100 ns molecular dynamics simulations were conducted to validate the binding mode and stability of psoralen with PINK1. The results showed that psoralen ameliorated H_2O_2-induced cell damage in a concentration-dependent manner, with the optimal concentration being 80 \u03bcmol\u00b7L~(-1). Psoralen significantly promoted cell proliferation, upregulated the expression of Runx2, Osterix, PINK1, and Parkin, enhanced mitochondrial membrane potential, increased mitophagy levels and osteogenic differentiation capacity, and enlarged mineralized nodule area. Simultaneously, it inhibited apoptosis, reduced intracellular ROS content, and downregulated the expression of autophagy substrate p62. Molecular docking results showed that the binding energy between psoralen and PINK1 was-7.024 kcal\u00b7mol~(-1), and 100 ns molecular dynamics simulations further confirmed the structural stability of the formed complex with persistent hydrogen bond interactions. In conclusion, psoralen directly targets and activates the PINK1/Parkin pathway to mediate mitophagy, clear damaged mitochondria, improve the oxidative stress microenvironment, promote the expression of osteogenic marker proteins and mineralization, thereby enhancing osteogenic differentiation of MC3T3-E1 cells, providing a new target and candidate drug for the prevention and treatment of osteoporosis.",

A COPD model was established in C57BL/6 mice by intratracheal instillation of lipopolysaccharide(LPS) combined with passive smoking exposure. The mice were randomly divided into a blank group, a model group, a tiotropium bromide group, and low-and high-dose Shenge Yifei Formula groups. Following a 5-week intervention, pulmonary function tests and HE staining were performed to assess lung histopathological changes. Flow cytometry, multicolor immunofluorescence, and ELISA were employed to detect the proportion and distribution of CD4~+ C-X-C chemokine receptor 3(CXCR3)~+ Th1 cells in lung tissue, as well as the levels of interferon-\u03b3(IFN-\u03b3), interleukin-12(IL-12), and C-X-C motif chemokine ligand 10(CXCL10) in bronchoalveolar lavage fluid(BALF). Additionally, transcriptomic sequencing was conducted on lung tissue from the high-dose Shenge Yifei Formula group. The study demonstrated that, compared with the model group, Shenge Yifei Formula significantly improved pulmonary function in COPD mice and attenuated alveolar structural damage, airway remodeling, and inflammatory cell infiltration in a dose-dependent manner. Mechanistic investigations revealed that the high dose of Shenge Yifei Formula markedly reduced the proportion and density of CD4~+CXCR3~+Th1 cells in lung tissue and decreased the levels of IFN-\u03b3, IL-12, and CXCL10 in BALF. Transcriptomic analysis further confirmed that its mechanism of action is closely associated with the modulation of immune pathways such as T cell differentiation and cytokine-cytokine receptor interaction. In conclusion, Shenge Yifei Formula effectively ameliorates pulmonary inflammation and dysfunction in COPD mice by inhibiting Th1 cell differentiation, recruitment, and the associated cytokine network. Unlike tiotropium bromide, which primarily improves ventilatory function, Shenge Yifei Formula exerts a significant inhibitory effect on the Th1 axis, suggesting a distinct advantage complementary to bronchodilator therapy at the level of immune inflammation. This study provides modern experimental evidence for the clinical application of Shenge Yifei Formula and indicates its therapeutic potential in COPD by concurrently targeting anti-inflammatory and anti-remodeling processes.",

By systematically reviewing relevant domestic and international research, this paper elaborated on the multi-target molecular mechanisms underlying the antidepressant effects of puerarin, including the regulation of the gut microbiota-gut-brain axis, inhibition of neuroinflammation, promotion of neurotrophy and neurogenesis, amelioration of oxidative stress and mitochondrial function, modulation of neurotransmitters and the hypothalamic-pituitary-adrenal(HPA) axis, and epigenetic modifications. The paper further highlighted its synergistically therapeutic potential in comorbidity models such as diabetes with depression and post-stroke depression, as well as its application in compound compatibility and the current status of clinical translation research. Despite breakthroughs in emerging fields like the regulation of neural circuit plasticity, intervention in neuronal apoptosis, and modulation of non-coding RNA networks, the clinical application of puerarin is primarily limited by its pharmacokinetic drawbacks, such as poor water solubility and low bioavailability, coupled with a lack of high-quality clinical evidence. This paper aims to provide a theoretical basis for developing puerarin into a novel antidepressant by deeply analyzing the complex network of its mechanisms and evaluating its prospects for clinical translation.",
"42543363": "ID: 42543363\nTitle: [Huangqin Qingre Chubi Capsules alleviate rheumatoid arthritis by inhibiting entry of intestine-derived LPS into bloodstream and blocking M1 macrophage-FLS cell communication].\nAbstract: This study aimed to investigate the therapeutic effect of Huangqin Qingre Chubi Capsules(HQC) on rheumatoid arthritis(RA) and the mechanism of inhibiting RA macrophage polarization by reducing the entry of intestine-derived lipopolysaccharide(LPS) into the bloodstream. ELISA and 16S rRNA analysis were used to assess the inhibitory effect of HQC on LPS in the intestinal contents of mice in vivo. The effect of HQC on macrophage proliferation was detected by CCK-8 assay to determine the appropriate dose of drug-containing serum. RT-qPCR and immunofluorescence assay were used to detect the expression of genes related to macrophage polarization. Transcriptomics was used to predict the biomolecular function of macrophages upon LPS stimulation, and molecular docking was utilized to verify the binding of key HQC components to Wnt family member 7b(Wnt7b). Following co-culture of macrophages with fibroblast-like synoviocytes(FLS), RT-qPCR, Western blot, scratch assay, flow cytometry, and immunofluorescence assay were employed to investigate the regulatory mechanism of HQC on M1 macrophage-FLS communication via the Wnt/\u03b2-catenin signaling pathway. The results showed that LPS was highly expressed in the intestinal contents of collagen-induced arthritis(CIA) model mice, and HQC administration exhibited a negative correlation with this expression. M1 macrophages promoted the expression of inflammatory factors such as inducible nitric oxide synthase(iNOS), tumor necrosis factor-\u03b1(TNF-\u03b1), and interleukin-6(IL-6), and also increased oxidative activity; these effects could be reversed by HQC. Transcriptomic analysis predicted that the Wnt/\u03b2-catenin signaling pathway was highly correlated with the effect of HQC on macrophage polarization in RA treatment. HQC-containing serum inhibited FLS migration, promoted apoptosis, and suppressed the expression of key genes in the Wnt signaling pathway, including c-Myc, CCND1, and \u03b2-catenin. Molecular docking indicated strong binding affinity between key components of HQC and Wnt7b. Overexpression of Wnt7b in macrophages, followed by co-culture with FLS, significantly interfered with the therapeutic effects of HQC. These findings demonstrated that HQC alleviates RA by inhibiting the entry of intestine-derived LPS into the bloodstream, thereby blocking M1 macrophages-FLS communication.",

A rat model of middle cerebral artery occlusion(MCAO)-induced IS was established using the modified suture occlusion method. Ninety Sprague-Dawley(SD) rats were randomly divided into the sham operation(sham) group, the model(model) group, ECA low-, medium-and high-dose groups(ECA-L, ECA-M, ECA-H), and the positive drug nimodipine(NMDP) group. The therapeutic effects of ECA were evaluated by neurological deficit scores, 2,3,5-triphenyltetrazolium chloride(TTC) staining, serum biochemical assays, hematoxylin-eosin(HE) staining, and Nissl staining. Transcriptomic and metabolomic analyses were performed on brain tissues from the sham, model, and ECA-H groups. Core gene expression was verified using real-time fluorescence quantitative polymerase chain reaction(RT-qPCR). The results showed that ECA significantly reduced neurological deficit scores and cerebral infarct volume, ameliorated pathological damage in the cerebral cortex, and dose-dependently downregulated the inflammatory factor levels and oxidative stress markers in IS rats. Transcriptomic analysis revealed that ECA-H regulated the expression of 328 differentially expressed genes(DEGs) in the model group, with 129 genes identified as core regulatory targets. Gene Ontology(GO) enrichment analysis showed that these DEGs were mainly involved in IS-related processes, including cerebral cortex development and neuronal development. Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis showed that the DEGs were primarily enriched in pathways such as the calcium signaling pathway and the cyclic adenosine monophosphate(cAMP) signaling pathway. RT-qPCR verification demonstrated that ECA significantly upregulated the relative expression levels of 10 genes related to these two signaling pathways. Metabolomic analysis revealed that ECA-H significantly regulated the levels of 11 differential metabolites in rat brain tissues, mainly involving metabolic pathways such as folate-mediated one-carbon metabolism, lysine degradation, and cysteine and methionine metabolism. In summary, the ECA exerts neuroprotective effects in IS by synergistically activating the calcium and cAMP signaling pathways, targeting the expression of core genes, and regulating key metabolic pathways, thereby inhibiting neuroinflammation, balancing oxidative stress, and alleviating neuronal damage.",

Forty male C57BL/6 mice(6-8 weeks old, SPF grade) were randomly assigned to four groups(n=10 per group): control group, model group, Xiaoyao San group(7.63 g\u00b7kg~(-1)), and fluoxetine hydrochloride group(4.11 mg\u00b7kg~(-1)). Except for the control group, all groups underwent 28 days of chronic unpredictable mild stress(CUMS) to establish the model. Behavioral tests were conducted on day 28. From day 29, the Xiaoyao San and fluoxetine hydrochloride groups received corresponding drug solutions via oral gavage for 28 days(once daily), while the control and model groups received equivalent volumes of saline. CUMS modeling continued uninterrupted during the administration period. Behavioral assessments were repeated on day 56, with body weight monitored throughout the experiment. Hematoxylin-eosin(HE) staining was used to observe pathological changes in intestinal tissues. The villus height and crypt depth were measured, and their ratio was calculated. Immunohistochemistry(IHC) was employed to detect the expression of tight junction proteins zonula occludens-1(ZO-1) and occludin in the intestinal mucosa. Serum levels of interferon-\u03b3(IFN-\u03b3), interleukin(IL)-2, IL-4, IL-10, corticosterone(CORT), gastrin(GAS), motilin(MTL), and somatostatin(SS) were measured using enzyme-linked immunosorbent assay(ELISA) and subjected to correlation analysis. Western blot was performed to assess T-box transcription factor T-bet and GATA-binding protein 3(GATA-3) protein expression in the hypothalamus and intestinal tissues. The results demonstrated that Xiaoyao San significantly alleviated CUMS-induced depressive-like behaviors, including weight loss, reduced sucrose preference, and decreased locomotor activity in the open field test. HE staining indicated that Xiaoyao San effectively restored intestinal villus structure and increased the villus height-to-crypt depth ratio. IHC results showed that Xiaoyao San enhanced the expression of occludin and ZO-1 related to intestinal mucosal barrier, suggesting improved intestinal barrier function. ELISA analysis revealed that Xiaoyao San significantly decreased serum levels of CORT, SS, IFN-\u03b3, and IL-2, while increasing GAS, MTL, IL-4, and IL-10, indicating mitigation of stress-induced damage and inflammatory responses, as well as regulation of brain-gut peptide secretion. Western blot results showed that Xiaoyao San significantly reduced T-bet protein expression and the T-bet/GATA-3 ratio in both the hypothalamus and intestinal tissues, suggesting correction of Th1/Th2 immune imbalance induced by CUMS. Correlation analysis indicated significant associations between brain-gut peptides and Th1/Th2-related inflammatory factors, implying a link between Th1/Th2 inflammatory responses and brain-gut regulatory function. In conclusion, Xiaoyao San ameliorates brain-gut interaction disorders in chronic stress mice, potentially through restoring Th1/Th2 immune balance, attenuating inflammatory responses, and modulating "brain-gut" peptide secretion.",

Although therapeutic strategies that disrupt this balance to induce lethal oxidative stress and ferroptosis have emerged as promising anticancer approaches, the upstream signaling mechanisms that constrain ROS accumulation under physiologically relevant stress conditions remain incompletely understood. Here, we identify the stress-responsive kinases SMG1 and DNA-dependent protein kinase (DNA-PK) as functionally redundant regulators of redox homeostasis and ferroptosis resistance. Genetic or pharmacological inhibition of either kinase triggers ferroptotic cell death, accompanied by marked accumulation of total ROS, ferrous iron, and lipid hydroperoxides. Mechanistically, under mild oxidative stress, SMG1 and DNA-PK cooperatively phosphorylate the central antioxidant transcription factor NRF2 at serine 13 and serine 40, weakening its interaction with the negative regulator KEAP1 and promoting NRF2 accumulation and transcriptional activation. Transcriptomic profiling of de novo mRNAs revealed that inhibition of either kinase is sufficient to suppress NRF2-driven antioxidant gene expression. In contrast, excessive oxidative stress overrides this pro-survival pathway and redirects signaling toward anti-survival responses mediated by ATF4, ATM-CHK2, and JNK/p38 pathways. Collectively, these findings uncover a previously unrecognized SMG1/DNA-PK-NRF2 signaling axis that functions as a redox stress-intensity-dependent switch governing cell fate decisions between antioxidant adaptation and ferroptotic death. Targeting this axis may represent a promising therapeutic strategy for cancer treatment.",

Cellmorphology, metabolic activity assessed by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay, and total protein, tumornecrosis factor-alpha (TNF-\u03b1), and interleukin-6 (IL-6) levels measured by enzyme-linked immunosorbent assay (ELISA) were analyzed at 24 and 48hours. PBM combined with DEXA at 2 \u03bcM increased MTT metabolic activity at 24 hours and was associated with preserved morphology and maintainedhigher total protein levels, with consistent superiority over DEXA alone. PBM + DEXA 2 \u03bcM produced the strongest reduction in TNF-\u03b1 and IL-6 at 24hours, and IL-6 levels remained lower at 48 hours compared to the M1 + PBM group. The 4 \u03bcM dose demonstrated lower efficacy and signs of functionalimpairment, which were partially mitigated by PBM. These findings indicate that PBM may enhance the anti-inflammatory effects of low-dose DEXA while supporting a favorable cellular metabolic response, suggesting its potential as an adjunct strategy to optimize the glucocorticoid-based modulation ofinflammatory responses.",
"42543445": "ID: 42543445\nTitle: The potential therapeutic effect of quercetin on mitochondrial dysfunction in hepatorenal toxicity induced by aluminum chloride in an experimental rat model.\nAbstract: Aluminum is a xenobiotic element known to induce hepatorenal toxicity through mechanisms involving mitochondrial dysfunction, oxidative stress, and inflammation. Quercetin, a dietary flavonoid with potent antioxidant and anti-inflammatory properties, has shown promise as a therapeutic agent. This study aimed to evaluate the potential therapeutic effects of quercetin against aluminum chloride (AlCl\u2083)-induced hepatorenal toxicity and mitochondrial dysfunction in rats. Hepatorenal toxicity was induced by oral administration of hydrated aluminum chloride (75 mg/kg body weight) daily for six weeks. Quercetin was administered intraperitoneally at a dose of 30 mg/kg body weight daily for four weeks. Biochemical assays, mitochondrial gene expression analysis, and histopathological examinations were conducted to assess the therapeutic effects. Quercetin significantly ameliorated lipid, protein, and DNA oxidation parameters (MDA, AOPPs and 8-OHdG respectively), reduced inflammation marker (TNF-\u03b1), and restored mitochondrial biogenesis markers, including PGC-1\u03b1, mtTFA and mitochondrial DNA copy number (mtDNA-CN). In addition, Quercetin significantly decreased TNF-\u03b1 and increased PGC-1\u03b1 contents at protein levels. Histopathological findings corroborated these results, demonstrating that quercetin improved liver and kidney architecture. These findings suggest that quercetin may serve as a potential therapeutic agent for aluminum-induced hepatorenal toxicity.",

MicroRNAs (miRs) are also involved in MDD through posttranscriptional regulation of gene expression. This study investigated whether miR-20a-5p regulates IRF1 in MDD. IRF1 mRNA and miR-20a-5p expression levels were measured by qPCR in postmortem hippocampi from 14 MDD subjects and 14 controls, and in chronic social defeat stress (CSDS) mice. Their regulatory relationship was examined in HEK293 cells using miR-20a-5p overexpression and a dual-luciferase assay. Neuro2a cells treated with DMSO were used to evaluate the effects of cellular stress on Irf1 and miR-20a-5p expression. IRF1 mRNA and miR-20a-5p expression levels were significantly increased in both MDD hippocampi and CSDS mice. Luciferase assays showed that miR-20a-5p directly targeted the conserved seed sequence within the IRF1 3'-UTR and suppressed IRF1 expression. During the early phase of cellular stress, Irf1 mRNA was upregulated, whereas miR-20a-5p was downregulated, suggesting that stress initially induces Irf1 expression, followed by secondary regulation of miR-20a-5p. IRF1 mRNA expression was increased in the hippocampus of both MDD subjects and CSDS mice. Moreover, miR-20a-5p directly targeted the IRF1 3'-UTR, supporting a potential miR-20a-5p-IRF1 regulatory axis involved in inflammatory signaling in MDD. However, its functional significance in vivo remains to be determined.",
"42543530": "ID: 42543530\nTitle: Impact of 3-day turmeric supplementation on fasting and postprandial LPS and chylomicron-related markers in patients with IBS: A randomized crossover trial.\nAbstract: Lipopolysaccharide (LPS) has been implicated in increased gut permeability and low-grade mucosal inflammation, conditions that are linked to the pathophysiology of irritable bowel syndrome (IBS). Because increased dietary fat intake can both trigger IBS symptoms and promote LPS translocation in the gut, this study aimed to better understand how a turmeric formula (TF) affects fasting and postprandial LPS response, after a high-fat challenge in patients with IBS (primary outcome). Secondary outcomes included postprandial ApolipoproteinB48 (Apo-B48) and triglycerides (TG) as markers of chylomicron-mediated LPS translocation, as well as gastrointestinal (GI) symptoms and stool pattern. In this randomized, double-blind, placebo-controlled cross-over trial, eighteen patients with IBS completed two high-fat challenge tests after 3-day supplementation with either 300 mg TF or placebo. Blood was collected in the fasting state and up to 5 hours postprandially. Data were analyzed using repeated measures mixed models. TF did not significantly alter postprandial LPS levels compared with placebo but significantly reduced postprandial Apo-B48 and TG (mean ratios 0.82 and 0.87, p=0.04 and p=0.01, respectively). Fasting LPS and TG showed a non-significant reduction after TF (mean ratios 0.79 and 0.87; both p=0.06, respectively). No differences were observed in gastrointestinal symptoms or stool characteristics. To conclude, TF did not influence dietary fat-mediated LPS translocation, but it reduced postprandial chylomicron markers, indicating a potential attenuation of chylomicron-mediated postprandial inflammation. Together with the observed trend towards reduced fasting LPS levels, these findings suggest that TF might have beneficial effects on low-grade subclinical inflammation, which could be relevant for IBS patients.",
"42543617": "ID: 42543617\nTitle: N-Acetylcysteine, Dichloroacetate, and Metformin Restore Mitochondrial Homeostasis by Counteracting Oxidative Stress and Fusion-Fission Imbalance in Palmitic Acid-Induced Lipotoxicity.\nAbstract: Palmitic acid (PA)-driven lipotoxicity in skeletal muscle is associated with excessive reactive oxygen species (ROS) and disturbed mitochondrial dynamics. This study aimed to characterize PA-induced alterations in oxidative status and fusion-fission balance in C2C12 skeletal muscle cells and to test whether N-acetylcysteine (NAC), dichloroacetate (DCA), or metformin mitigate these changes. Differentiated C2C12 myotubes were exposed to PA under conditions detailed in the Methods. Intracellular ROS was quantified, antioxidant defenses were assessed by activities of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD), and mitochondrial dynamics were evaluated by expression of the fusion protein mitofusin 1 (MFN1) and the fission protein dynamin-related protein 1 (DRP1), together with morphological assessment of mitochondrial fragmentation. PA exposure increased ROS and was accompanied by decreases in CAT, GPx, and SOD activities. PA shifted mitochondrial dynamics toward fission, with reduced MFN1, elevated DRP1, and increased mitochondrial fragmentation. Co-treatment with NAC, DCA, or metformin attenuated PA-induced ROS accumulation, improved antioxidant enzyme activities relative to PA alone, and partially normalized MFN1 and DRP1 expression, with reduced fragmentation. In an in vitro C2C12 model, PA-induced lipotoxicity is associated with oxidative stress and a fusion-fission imbalance favoring mitochondrial fragmentation. NAC, DCA, and metformin mitigate these alterations and help preserve mitochondrial homeostasis. These findings support targeting oxidative stress and mitochondrial dynamics as a potential approach to counteract mitochondrial dysfunction under lipotoxic conditions.",

The two RMSs were included at dietary levels of 0%, 2%, and 4% (as-fed basis) in an in\u00a0vitro experiment with triplicate incubations (n\u2009=\u20093). Gases were collected using an ANKOM Gas Production system and analyzed for methane (CH4) and nitrous oxide (N2O) via gas chromatography. The RMS supplementation increased total gas, lactate, butyrate, valerate, hexanoate, heptanoate, 4-ethylphenol production, and AGR (non-glucogenic [acetate\u2009+\u2009butyrate]/glucogenic [propionate]) ratio (p\u2009<\u20090.01), while reducing production of CH4 (mg/g DM), acetate, propionate, iso-butyrate, phenylpropionate, phenylacetate, and acetate/propionate (A/P) ratios (p\u2009<\u20090.01), and in\u00a0vitro dry matter digestibility (IVDMD; % DM) (p\u2009<\u20090.01) as RMS supplementation increased.

A narrative review synthesizing randomized controlled trials and observational microbiome studies in paediatric and adult populations, specifically distinguishing between probiotic monotherapy and adjunctive protocols. Observational data confirm gut microbiome alterations in ADHD populations, although specific bacterial signatures vary across studies. Evidence from treatment trials demonstrates that the efficacy of probiotics as monotherapy for core ADHD symptoms remains inconclusive. However, specific adjunctive trials combining probiotics with conventional medication have reported preliminary positive findings on symptom reduction, though results remain heterogeneous. Adult evidence is sparse but indicates potential benefits for emotional dysregulation in specific contexts. This review concludes that current data do not support universal probiotic supplementation or routine clinical recommendation. However, when families inquire about complementary approaches, the existing literature enables evidence informed guidance within a shared decision-making framework that acknowledges the preliminary nature of current findings and sets realistic expectations.",

Standard screening practices may miss mothers with later-onset symptoms. The pediatric emergency department (PED) may provide an opportunity to extend PPD screening beyond routine outpatient care. To evaluate the feasibility and utilization of Edinburgh Postnatal Depression Scale (EPDS) screening for PPD among mothers of children 12 months or younger presenting to a PED and to describe the demographics of screened patients. We conducted a retrospective descriptive study of EPDS screening implemented as a quality improvement initiative in an urban academic PED between May 15, 2023 and November 30, 2023. Biological mothers of children 12 months or younger were screened at triage using the EPDS in English or Spanish. Positive screens were defined as a score \u22659 or endorsement of suicidal ideation. Demographic data, Emergency Severity Index (ESI), insurance status, EPDS results, and documented interventions were abstracted from the electronic medical record. A total of 734 EPDS screens were completed. Forty-one mothers (5.6%) screened at risk or positive. Of these, 17 (41%) had infants aged 6 to 12 months. Maternal mental health resources were offered to 37 (90.2%) mothers with positive screens. All mothers with positive screens had public insurance. The screened population was predominantly white (41.1%) and Hispanic (41.1%). PPD screening in the PED for mothers of children up to 12 months of age is feasible and may identify at-risk mothers. PED-based screening may help address gaps in maternal mental health care for underserved populations.",
"42543917": "ID: 42543917\nTitle: Adaptation of White Adipocytes to Cooler Temperatures: Impacts on Energy Metabolism and Protein Acetylation.\nAbstract: Adipocytes throughout the body reside in distinct thermal environments. Visceral adipocytes within the body core are maintained near 37\u00b0C, whereas those in bone marrow, subcutaneous, and dermal depots occupy cooler regions within the peripheral shell. Although brown and beige adipocyte responses to cold stress are well characterized, much less is known about how white adipocytes adapt to moderately reduced temperatures below 37\u00b0C. Our recent work revealed that cultured adipocytes exposed to 31\u00b0C, a temperature representative of distal adipose regions, exhibit enhanced mitochondrial function, including increased substrate oxidation and ATP turnover, yet the mechanisms underlying this upregulation remain unclear. Here we show that adaptation to cool temperatures leads to a widespread decrease in protein acetylation in both undifferentiated and differentiated adipocytes, independent of nutrient status, and that this change is readily reversible upon rewarming. Subcellular fractionation and immunoblotting demonstrate that the hypoacetylation coincides with a compartment-specific enrichment of acetylated proteins within mitochondria, indicating selective remodeling of the mitochondrial acetylome. Transcriptomic and biochemical analyses reveal that these temperature-dependent changes occur without alterations in acetyltransferase or deacetylase expression, NAD+ concentration, or acetyl-CoA availability, suggesting regulation through alternative mechanisms affecting acetyl-CoA flux or enzyme activity. Integrative acetyl-proteomic and metabolomic profiling identifies mitochondrial enzymes, including serine hydroxymethyltransferase 2 (SHMT2) and propionyl-CoA carboxylase \u03b1 (PCCA), whose acetylation correlates closely with changes in associated metabolite pools. Together, these findings establish physiologically relevant cooling as a cell-autonomous regulator of mitochondrial protein acetylation and metabolic adaptation in adipocytes.",
"42544151": "ID: 42544151\nTitle: Comparative Evaluation of Salivary Chemerin and Malondialdehyde Among Patients With Periodontitis and Oral Squamous Cell Carcinoma: A Cross-Sectional Study.\nAbstract: Introduction Periodontitis and oral squamous cell carcinoma (OSCC) are long-lasting inflammatory conditions that lead to tissue damage, oxidative stress, and changes in immune responses. Recent studies indicate a potential biological link between periodontal inflammation and the development of oral cancer. Salivary biomarkers such as chemerin and malondialdehyde (MDA) may serve as non-invasive tools for early diagnosis and disease monitoring. This study was designed to assess and compare salivary chemerin and MDA levels in three groups: healthy individuals, patients with periodontitis, and those with OSCC. Methods This study was conducted on 75 participants distributed evenly among the three groups: healthy individuals (Group A), periodontitis patients (Group B), and OSCC patients (Group C). Clinical periodontal parameters, including Oral Hygiene Index-Simplified (OHI-S), Russell's periodontal index, probing pocket depth (PPD), and clinical attachment level (CAL), were recorded. Unstimulated saliva samples were collected and analyzed for chemerin and MDA levels using enzyme-linked immunosorbent assay (ELISA) kits. Statistical analysis was done using analysis of variance (ANOVA), Tukey's post hoc test, and Pearson's correlation coefficient, with p<0.05 considered statistically significant. Results Salivary chemerin and MDA levels showed a progressive increase from healthy controls to periodontitis patients and OSCC patients. One-way ANOVA revealed statistically significant differences among the three groups for both chemerin (F(2,72)=4.28; p=0.017) and MDA (F(2,72)=3.45; p=0.037). Tukey's post hoc analysis demonstrated significant pairwise differences between all groups for both biomarkers (p<0.001), indicating increasing levels with disease severity. Pearson's correlation analysis showed a statistically significant positive correlation between chemerin and MDA, suggesting an association between inflammatory and oxidative stress pathways in periodontal disease. Conclusion Salivary chemerin and MDA levels were significantly increased in periodontitis and OSCC patients, with the highest levels observed in OSCC. These findings suggest that chemerin and MDA may serve as promising non-invasive salivary biomarkers for the diagnosis, risk assessment, and monitoring of periodontal disease and OSCC. Further large-scale longitudinal studies are recommended to validate their clinical applicability.",

Intestinal organoid-on-a-chip systems have emerged as advanced in vitro models that reproduce key features of the intestinal microenvironment and physiological function. These systems have shown promise for studying mucosal injury and repair, assessing therapeutic strategies, and supporting translational research. This review summarizes the basic principles of intestinal organoid-on-a-chip technology and examines its use in modeling intestinal barrier function, inflammatory responses, drug screening, regenerative approaches, and trauma-related barrier repair. It also reviews recent progress in preclinical studies, considers potential applications in gastrointestinal research, and discusses current technical challenges, particularly those related to scalability and reproducibility. Future directions for the development of next-generation systems are also outlined. With the continued integration of advances across disciplines, these platforms may provide useful tools for studying and treating disorders involving the intestinal mucosal barrier, especially in the context of trauma and burns.",

Plant-derived exosome-like nanoparticles have emerged as promising therapeutic agents due to their natural origin, biocompatibility, and capacity to deliver bioactive cargo. This study aimed to isolate exosome-like nanoparticles from the decoction of Magnolia biondii flower buds (Xinyi) (MFELNs) and evaluate their therapeutic potential in a murine model of UC. MFELNs were isolated from Xinyi decoction using differential centrifugation and ultracentrifugation. MFELNs were characterized by transmission electron microscopy, nanoparticle size and potential analysis, and metabolomic profiling. The in vitro antioxidant activity was assessed by DPPH scavenging and intracellular ROS suppression assays. Anti-inflammatory effects were evaluated in LPS-stimulated RAW 264.7 macrophages by measuring cytokine expression and macrophage polarization via flow cytometry. The promotion of cell migration was assessed in NIH3T3 cells by scratch assay. UC was induced in C57BL/6 mice using dextran sodium sulfate (DSS), and MFELNs were orally administered daily for 14 days. Disease activity index, colon length, histopathology, colonic cytokine expression, and gut microbiota composition were evaluated. Bioinformatics analysis, molecular docking, and Western blot were performed to elucidate the underlying molecular mechanisms. MFELNs exhibited typical exosome-like morphology with a size of 66.7 \u00b1 1.3 nm and a negative surface charge. Metabolomic profiling revealed enrichment in flavonoids, alkaloids, lignans, and phenolic acids. MFELNs demonstrated satisfactory biocompatibility and gastrointestinal stability. In vitro, MFELNs scavenged DPPH radicals, suppressed H2O2-induced ROS generation, downregulated LPS-induced pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6), restored IL-10 expression, and promoted macrophage polarization from M1 to M2 phenotype. In vivo, MFELNs attenuated DSS-induced body\u2011weight loss, reduced DAI scores, prevented colon shortening, and alleviated histopathological damage. MFELNs downregulated colonic pro-inflammatory cytokines and restored IL-10 expression. Gut microbiota analysis revealed that MFELNs restored the DSS-elevated Firmicutes/Bacteroidota ratio without significantly affecting \u03b1-diversity. Bioinformatics screening identified four potential bioactive components (sesamin, litsoeine/laurotetanine, demethylwedelolactone, and armepavine) that target SRC. Molecular docking demonstrated favorable binding between these components and SRC, while Western blot confirmed that MFELNs suppressed the SRC/NF-\u03baB signaling pathway. MFELNs represent a novel class of decoction-derived exosome-like nanoparticles that ameliorate UC through integrated anti-inflammatory, antioxidant, and microbiota-modulating mechanisms. Their therapeutic effects are mediated, at least in part, through suppression of the SRC/NF-\u03baB signaling pathway. These findings position MFELNs as a promising natural nanotherapeutic strategy for UC and support the concept that self-assembled nanoparticles formed during herbal decoction constitute an important material basis for the efficacy of traditional Chinese herbals.",

This study investigated whether dexmedetomidine liposomes (Dex-lip) exert neuroprotective effects by modulating astrocytic aerobic glycolysis via calcium signaling. In vivo CIRI model mice received Dex-lip, with or without the aerobic glycolysis inhibitor 2-deoxy-D-glucose (2-DG). Neurological function, cortical calcium levels, aerobic glycolysis-related protein expression, lactate production, and hippocampal neuronal damage were assessed. In vitro, astrocytes were treated with the calcium channel blocker nifedipine to evaluate intracellular calcium, lactate levels, and glycolysis-related gene expression. Dex-lip treatment reduced cortical calcium overload, upregulated aerobic glycolysis key proteins, increased lactate production, and attenuated hippocampal neuronal injury. These neuroprotective effects were abolished by 2-DG. In vitro, nifedipine lowered astrocytic calcium concentration, which paradoxically increased lactate production, elevated ECAR, and upregulated HK1, HK2, and PFK1 mRNA expression, confirming that calcium reduction promotes aerobic glycolysis. Dex-lip ameliorates CIRI by reducing astrocytic calcium overload, enhancing aerobic glycolysis and lactate supply to neurons, thereby preventing apoptosis. This study provides a mechanistic basis and therapeutic strategy for CIRI.",
"42544394": "ID: 42544394\nTitle: Long-term moderate lard intake reduces susceptibility to colitis and secondary liver injury in mice.\nAbstract: The role of dietary fats in inflammatory bowel disease is source-dependent. Lard has long been considered a less favorable dietary fat, yet its effects on intestinal health may be dose-dependent, and the mechanisms remain poorly understood. In this study, a dextran sulfate sodium (DSS)-induced colitis model was used to investigate the effects of moderate intake of different dietary fats-lard, beef tallow (beef), and corn oil (corn)-on colitis and secondary liver injury. We found that, compared to beef or corn, lard reduced susceptibility to DSS-induced colitis, as evidenced by less severe colonic inflammation, enhanced intestinal barrier integrity with upregulation of tight junction proteins (ZO-1, Occludin, Claudin1), and reduced colonic and systemic levels of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, lard-fed mice exhibited less severe secondary liver injury than beef- or corn-fed mice, as indicated by decreased serum ALT/AST levels, lower hepatic LPS accumulation, and reduced oxidative stress markers (MDA, protein carbonyl, 3-nitrotyrosine). Untargeted metabolomics revealed that lard enriched specific intestinal metabolites, including crispolide, steviol, swertiamarin, genipin, and several diglycerides. Hepatic transcriptomics and RT-qPCR validation further showed that lard specifically activated the PPAR signaling pathway and fatty acid degradation pathway, which was corroborated at the protein level by elevated PPAR\u03b1 and PPAR\u03b3 expression. Spearman correlation analysis established positive associations between key intestinal metabolites and critical genes involved in these pathways. These results demonstrated that moderate lard intake reduced susceptibility to DSS-induced colitis and secondary liver injury compared to beef or corn, potentially through modulation of gut-liver crosstalk.",
"42544450": "ID: 42544450\nTitle: Gene dosage imbalance disrupts systemic metabolism in the Dp16 Down syndrome mouse model.\nAbstract: Gene dosage imbalance resulting from an extra copy of human chromosome 21 (Hsa21) contributes to numerous clinical features in Down syndrome (DS). While dysregulated metabolism has long been noted in DS, the underlying cause is poorly understood and vastly understudied. To fill this critical knowledge gap, we conducted a comprehensive metabolic analysis of Dp(16)1Yey/+mice (abbreviated Dp16), a segmental duplication model carrying ~58% of the triplicated Hsa21 gene orthologs. Our multi-tissue transcriptomic analyses reveal shared and sex-specific increases in expression dosage of the triplicated genes in white and brown adipose tissues, liver, skeletal muscle, and hypothalamus. Despite sexual dimorphism in body weight, body temperature, food intake, and physical activity, Dp16 males and females share striking core phenotypes of pronounced insulin resistance, glucose intolerance, impaired lipid clearance, and dyslipidemia. Functional assessments, combined with biochemical, transcriptomic, and metabolomic analyses reveal tissue signatures of immune activation and a pro-inflammatory state, ER and oxidative stress, fibrosis, impaired glucose and fatty acid catabolism, altered lipid and bile acid profiles, and reduced mitochondrial respiratory capacity in Dp16 mice. These concerted changes disrupt homeostatic mechanisms that underpin metabolic health, contributing to systemic metabolic dysfunction. An obesogenic diet further exacerbates insulin resistance in Dp16 males and females despite divergent weight gain. The collective phenotypes broadly reflect the metabolic profile of DS. Our extensive molecular, biochemical, and physiological data provide an essential foundation for genetic dissection of dosage-sensitive genes affecting glucose and lipid metabolism, and for testing therapeutic strategies to improve metabolic outcomes in DS.",
"42544498": "ID: 42544498\nTitle: PPE18 protein of Mycobacterium tuberculosis downregulates LPS-induced IgG production by inhibiting nitric oxide synthesis.\nAbstract: Mycobacterial PPE18 is a virulence factor. Previous studies have demonstrated that recombinant PPE18 protein (rPPE18) downregulates inflammation-induced nitric oxide synthase (iNOS) and nitric oxide (NO) production. Given its ability to inhibit iNOS, we investigated whether rPPE18 can also affect IgG secretion, which is modulated by NO levels. Mouse splenocytes and purified B cells were stimulated with lipopolysaccharide (LPS) to induce iNOS-mediated NO as well as IgG and IgM production. The addition of rPPE18 to LPS-stimulated cells reduced NO and iNOS at both the transcript and protein levels. This was accompanied by a drop in total secreted IgG, which could be reversed by the addition of SNAP, an NO donor. Importantly, rPPE18 did not affect secreted IgM levels. These data suggest that rPPE18 interferes with NO-dependent antibody class-switching from IgM to IgG. This was further confirmed by significantly reduced transcript levels of activation-induced cytidine deaminase (AID) in rPPE18-treated LPS-stimulated splenocytes. AID is crucial for class-switch recombination and is regulated by NO levels. These data highlight a novel mycobacterial virulence mechanism, in which rPPE18 inhibits IgG secretion and dampens protective humoral immunity, which is a critical component of the host anti-mycobacterial response."
