Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p).

B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum.

The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants."

In this study, we demonstrated that A. muciniphila administration improve cognitive deficits and reduce amyloid-beta (A\u03b2) deposition in APP/PS1 mice, a transgenic model of AD. Subsequently, it is revealed that A. muciniphila administration significantly alters gut microbiota diversity and composition. Mechanically, our metabolomics analysis of cecal contents indicates A. muciniphila administration increases short-chain fatty acids (SCFAs) derived from the intestinal microbiota, including butyric acid and acetic acid. Significantly, in APP/PS1 mice with the A. muciniphila administration, targeted metabolomics identify that the production of 62 metabolites are increased such as indole-3-acetic acid (IAA), tryptophan, acetic acid and cinnamic acid, as well as aconitic acid and threonine, et al.; the production of 28 metabolites are decreased such as isoleucine and N-acetylneuraminic acid (NANA) as well as ornithine and docosapentaenoic acid (DPA), et al. It is also identified by cytokine analysis of plasma that A. muciniphila administration reduces peripheral pro-inflammatory cytokines interleukin-6 (IL-6), IL-1\u03b2, IL-17 and tumor necrosis factor-alpha (TNF-\u03b1), et al., whereas it increases anti-inflammatory cytokines, such as IL-4, IL-10 and IL-22, et al. There is no any change of other cytokines, such as interferon-gamma (IFN-g), IL-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF), et al. Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators. At the same time, A. muciniphila administration improves cognitive deficits, alleviates neuroinflammation and A\u03b2 deposition via AhR/NF-\u03baB/NLRP3 signaling pathway in APP/PS1 mice. In summary, our findings suggest A. muciniphila is a promising approach for preventing AD progression by microbiota-gut-brain axis."

Roseburia intestinalis (R. intestinalis) is consistently reduced in PD; however, its functional contribution remains unknown. We performed two complementary mouse experiments using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model. In the primary intervention experiment, mice received live or heat-killed R. intestinalis, followed by behavioral assessments and multi-layer analyses, including immunofluorescence, western blotting, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, 16S rRNA sequencing, metabolomics, and transcriptomics. In a separate mechanistic experiment, subdiaphragmatic vagotomy was introduced to interrogate vagus-dependent gut-brain communication, with key behavioral and inflammatory endpoints assessed. Live R. intestinalis improved rotarod, pole, and grip strength performance and preserved tyrosine hydroxylase-positive neurons in the substantia nigra; however, these effects were not observed in the heat-killed group. Live R. intestinalis treatment also reduced glial reactivity, restored brain-derived neurotrophic factor expression, and maintained blood-brain barrier integrity. Systemically, R. intestinalis lowered serum lipopolysaccharide, tumor necrosis factor-\u03b1, and interleukin-6 levels; preserved colonic structure; and restored mucin-secreting goblet cell function. MPTP-induced dysbiosis was partially corrected. Metabolomic profiling revealed restoration of several acyl-carnitines and higher acetic acid levels. Transcriptomic analysis showed increased immediate early genes after MPTP, and the elevated c-Fos in the substantia nigra was partially normalized by R. intestinalis. Importantly, vagotomy abolished the central neuroprotective and anti-inflammatory effects but did not affect peripheral cytokine suppression, indicating both vagus-dependent and vagus-independent pathways. R. intestinalis supplementation alleviated motor impairments, reduced neuroinflammation, preserved dopaminergic neurons, and improved intestinal and metabolic alterations in mice with an MPTP-induced PD model. Its protective actions may involve both central and peripheral mechanisms, potentially including gut-brain communication pathways. R. intestinalis may be a promising candidate for microbiota-based strategies against PD."

However, studies on drugs addressing the concurrent amelioration of these symptoms in this patient population are rare. Previous studies have suggested that dihydromyricetin (DHM) may show therapeutic potential for IBD. This study investigated the therapeutic effects of DHM on dextran sulfate sodium (DSS)-induced colitis and associated behavioral disorders in mice. The findings of the experiments indicated that DHM could ameliorate colitis symptoms, including changes in body weight, colon length, disease activity index (DAI) scores, and histopathological damage. Furthermore, DHM improved the behavioral impairments observed in colitis mouse model, as evidenced by results from the open field test, elevated plus maze test, and tail suspension test, along with hippocampal histopathological assessments. Molecular analysis revealed that DHM notably suppressed the activation of NLRP3 inflammasome and IL-1\u03b2 in both the colon and the hippocampus. DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation.

Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces. Network pharmacology analysis identified the central intersecting genes of DHM, ulcerative colitis (UC), and neuroinflammation. Differential gene expression analysis underscored IL-1 \u03b2 as a pivotal target for the co-occurrence of UC and psychiatric conditions.

Corylus heterophylla Fisch. male flower extract (CFE), a flavonoid-rich by-product of hazelnut processing, presents a promising yet unexplored neuroprotective candidate. This study investigated the preventive effects and mechanisms of CFE against HNF-induced cognitive decline. Methods: In the present study, mice were pretreated with CFE (200 mg/kg) before the Lipopolysaccharide (LPS) administration. Cognitive function, inflammation, core pathology, neuroplasticity, gut microbiota and serum metabolites were assessed. The chemical composition of CFE was analyzed by UHPLC-MS and its direct immunomodulatory effects were investigated in BV2 cells. Results: Behavioral assessments demonstrated significant therapeutic efficacy. This was evidenced by the recovery from hippocampal damage, accompanied by reduced levels of core pathological markers (A\u03b21-42, Tau, p-Tau (Ser404), GSK-3\u03b2), decreased expression of pro-inflammatory mediators including IL-33, elevated levels of neurotrophic factors (BDNF and MAP2), and attenuated abnormal activation of astrocytes and microglia.

Notably, CFE significantly increased the relative abundance of Muribaculaceae and Lachnospiraceae, while significantly decreased Staphylococcus and Helicobacter. Metabolomics revealed enhanced levels of \u03b1-linolenic acid (ALA), serotonin (5-HT) and acetic acid, which correlated positively with Muribaculaceae and Lachnospiraceae. Phytochemical analysis identified luteolin and kaempferol as the predominant flavonoids in CFE.

Sacc.Chaidam on gut microbiota in Tibetan Plateau population based on in vitro model.\nAbstract: The intercellular polysaccharides derived from Agaricus bitorquis (Qu\u00e9l.) Sacc. Chaidam (ABIPs) are macromolecules exhibiting significant biological activity and outstanding anti-hypoxia properties. However, the digestive traits of ABIPs within the intestinal microbiota and their adaptive mechanisms to hypoxia in high-altitude populations remain poorly understood. The objective of this study was to investigate the anti-hypoxia mechanism of ABIPs at the small-molecule level through the utilization of the in vitro fermentation model of intestinal flora and the cell hypoxia models. The results indicated that under conditions of hypoxic stress, the total amount of monosaccharides and uronic acids (MUAs) metabolized by ABIPs in the plateau group was comparatively high, predominantly mannose. Furthermore, the level of short-chain fatty acids (SCFAs) produced through their metabolism was also significantly higher than that of the plain group, with acetic-acid, propionic-acid, and butyric-acid constituting a relatively large proportion. Additionally, in the plateau group, the metabolism of ABIPs increased the abundance of Prevotella and Alloprevotella, while the abundance of Collinsella decreased notably. In contrast, the metabolites produced by ABIPs in the plateau group (mainly SCFAs) had a more pronounced inhibitory effect on the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) signaling pathway than in the plain group. Overall, ABIPs may enable cells to develop hypoxia tolerance by enhancing hypoxia-consuming metabolic levels, rebalancing the gut microbiota, and stabilizing the HIF-1\u03b1 signaling pathway, thereby protecting the body from hypoxia damage."

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

Clinical observations have shown that Liqi Yangyin (LQYY) can effectively relieve symptoms of depression accompanied by constipation. However, whether LQYY exerts its effects through gut-brain crosstalk remains to be elucidated. A chronic unpredictable mild stress (CUMS) protocol was employed to establish a mouse model. H&E and Nissl staining were used to examine pathological changes in the prefrontal cortex (PFC) and colon. The ultrastructure of the intestinal barrier was observed via transmission electron microscopy, while the expression of the blood-brain barrier tight junction proteins was quantified by Western blotting (WB). ELISA quantified inflammatory factors and serotonin (5-HT) levels. Immunohistochemistry, immunofluorescence, and WB analyzed IBA-1 and Free fatty acid receptor 2 (FFAR2) expression levels. Gut microbiota composition was analyzed via 16S rDNA sequencing, and SCFAs levels were quantified using UHPLC-TSQ Altis Plus. Additionally, in vitro studies using BV-2 cells involved treatments with acetic acid (ACE) and an FFAR2 antagonist, after which the expression of relevant indicators was assessed. Our results demonstrated that LQYY significantly ameliorated CUMS-induced behavioral changes and improved intestinal motility. These effects were associated with the restoration of gut microbiota balance and an increase in ACE levels. LQYY increased FFAR2 expression, leading to reduced neuroinflammation and enhanced colonic 5-HT secretion. Furthermore, LQYY protected intestinal and blood-brain barrier integrity and improved neuronal morphology in the PFC. In vitro studies confirmed that ACE suppresses microglial inflammation through upregulating FFAR2 expression, an effect that was attenuated by the FFAR2 inhibitor GLPG0974. These findings suggest that LQYY modulates the gut-brain axis through ACE/FFAR2, offering a promising therapeutic approach for depression and constipation."

Their analysis highlights lactate's expanding role beyond a metabolic byproduct, emphasizing its functions in cellular signaling, antioxidant defense, and neuroprotection. Our study demonstrated that NaL improved acid-base balance without adverse effects, likely through lactate's conversion to bicarbonate and potential support for mitochondrial function. The commentary further explores NaL's translational relevance in neonatal hypoxia-ischemia (NHI), where lactate may serve as a key neuroenergetic substrate and modulate inflammation and gene expression. While the Rice-Vannucci model has limitations, it remains valuable for long-term studies, as shown in our prior work. We agree that larger animal models offer enhanced physiological relevance but face practical constraints. Future research should compare NaL with sodium acetate (NaA), a standard in neonatal care, to assess relative benefits in correcting acidosis and supporting neurodevelopment. We support the call for randomized, multicenter studies with long-term follow-up to fully evaluate NaL's therapeutic potential in preterm and at-risk neonates. IMPACT: L-lactate is a key component of the astrocyte-neuron lactate shuttle, supporting brain energy metabolism. Ibrahim et al. suggest sodium L-lactate as an alternative maintenance fluid for preterm newborns. L-lactate should not be regarded merely as a simple fluid replacement. L-lactate acts as a signaling molecule, impacting cellular metabolism and brain development. Additional research is required to assess the potential benefits and safety of sodium L-lactate in newborns."

This therapy involves the use of Myristica fragrans Houtt. and Carum carvi L., along with fomentation and massage, and has shown significant clinical effects. However, the mechanism of how Huoermai therapy treats plateau insomnia needs further clarification. This study aimed to investigate the mechanism of action of Huoermai essential oil (HEO) in treating plateau insomnia, focusing on the cAMP/CREB/BDNF/GABAergic pathway. The major components of Huoermai essential oil were identified by Gas chromatography-mass spectrometry (GC-MS) for subsequent network pharmacology analysis. Proteomics techniques were employed to pinpoint disparities in brain tissue protein expression in a mouse model of plateau insomnia following Huoermai therapy administration, in conjunction with network pharmacology to forecast pathways related to hypoxia and insomnia. Plateau insomnia mouse model was established and the therapeutic impact of Huoermai essential oil was evaluated. Hematoxylin & Eosin staining(HE) was conducted to observe pathological damage to the cortex, hippocampus, thalamus and hypothalamus structures. Changes in serotonin (5-HT), melatonin (MT), adenosine (AD), cyclic adenosine monophosphate (cAMP) and malondialdehyde (MDA) levels in mouse brain tissue were gauged through enzyme-linked immunosorbent assay (ELISA) to assess sleep status and oxidative stress levels in mice. Molecular docking was employed to anticipate the target binding energy of Huoermai essential oil constituents. ELISA and Western Blot (WB) were used to ascertain the expression of cAMP/CREB/BDNF/GABAergic pathway. The results indicated that HEO positively impacted intermittent hypobaric hypoxia-induced plateau insomnia in mice. Histological examination results showed that HEO ameliorated neuronal damage in specific regions of the brain affected by plateau insomnia, such as the cortex, hippocampus, thalamus, and hypothalamus. Through GC-MS analysis, 56 volatile oil components were identified. Subsequently, a combined network pharmacology and proteomics analyses led to selecting the cAMP/CREB/BDNF/GABAergic pathway for further study. ELISA experiments demonstrated that HEO treatment increased GABA and MT levels while significantly reducing 5-HT and adenosine levels in brain tissue of mice with plateau insomnia. WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress. Moreover, molecular docking results showed strong binding affinity of all pharmacological components to their targets and proteins in the brain. These results indicate that HEO significantly prolongs sleep duration in plateau insomniac mice and treats plateau insomnia by modulating levels of sleep-related regulators, modulating the cAMP pathway, increasing GABA receptor expression, and improving neuronal survival and anti-apoptosis."

It was aimed to elucidate the potential therapeutic effect of estrogen receptor agonists on NEC-induced intestinal and brain injury in rats. Sprague-Dawley pups of both sexes were separated from their mothers at postnatal 5th d. Feeding with formula along with a single session of hypoxia was applied to induce NEC, while control pups were kept with their mothers. The NEC rats received either vehicle, estrogen receptor \u03b1 (ER\u03b1) agonist propyl pyrazole triol (1\u00a0mg/kg/day), ER\u03b2 agonist diarylpropionitrile (1\u00a0mg/kg/day), or 17\u03b2-estradiol (1\u00a0mg/kg/day) during maternal separation. All pups were decapitated on postnatal 9th d to collect intestinal and brain tissue samples. Elevation in proinflammatory cytokines, apoptosis, and microscopically and biochemically evident oxidative injury in both the intestinal and brain tissues were observed in NEC-induced pups. In both the intestinal and brain tissues, nerve growth factor and brain-derived neurotrophic factor protein levels were depleted, expressions of both the ESR1 and ESR2 genes were downregulated, while treatment with 17\u03b2-estradiol or ER agonists alleviated extent of oxidative injury of the intestines and brain tissue, upregulated nerve growth factor, brain-derived neurotrophic factor, and ER gene expressions, abolished NEC-induced decrease in claudin-3 expression, increased the survival rates, improved the clinical states of the survived pups at varying degrees. Activation of estrogen signaling by receptor agonists alleviated NEC-induced intestinal and cerebral injury, implicating that estrogen agonists could be regarded as promising preventive/therapeutic agents for NEC."

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies."

Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and Amchi system of medicine. These are rich sources of diverse bioactive metabolites having prophylactic and therapeutic uses against a wide array of neurodegenerative diseases. The objective of this study was to elucidate the prophylactic and neuroprotective efficacy of formulated phytococktail (PC) against simulated HH-induced neurodegeneration in male Sprague Dawley (SD) rats. Materials and Methods: A PC containing H. rhamnoides fruit pulp, P. armeniaca fruit pulp, and R. imbricata dry root extract (100:50:1) was formulated. The neuroprotective efficacy of PC was evaluated in male SD rats following exposure to 7 day HH at simulated altitude (25,000 ft, 282\u2009mm Hg). Rats were divided into four groups viz., normoxia group (NOR), normoxic group treated with PC (NORPC), 7 day hypoxic group treated with vehicle (7DH), and 7 day hypoxic group treated with PC (7DHPC). Memory impairment and neuromorphological alterations were measured. Targeted protein expression was analyzed by immunoblotting study. Results: PC supplementation significantly reduced the oxidative stress markers during exposure to HH. Spatial memory impairment by HH was significantly ameliorated by PC. HH-induced augmented pyknosis, decreased dendritic arborization, and increased Hoechst-positive neurons in hippocampal CA3 region were significantly ameliorated by PC. Immunoblotting study showed upregulation of BDNF and TrkB expression by PC. PC also prevented the hippocampal neurodegeneration by activating the PI3K/AKT signaling pathway, which leads to GSK-3\u03b2 inactivation by its phosphorylation and alleviation of hippocampal Caspase3 expression leading to inhibition of apoptotic neuronal cell death. Conclusion: The present study advocates the potential role of PC as an effective neuroprotective supplement in preventing HH-induced neurodegeneration. Activation of the PI3K/Akt pathway through BDNF/TrkB interaction following PC supplementation after exposure to HH inhibits hippocampal neuronal apoptosis and memory impairment."

Previous studies suggested that epigenetic modifications are the culprits for this condition. Here, we set out to determine how hypobaric hypoxia mediates epigenetic modifications and how this condition worsens neurodegeneration and memory loss in rats. In the current study, different duration of hypobaric hypoxia exposure showed a discrete pattern of\u00a0histone acetyltransferases\u00a0and histone deacetylases (HDACs)\u00a0gene\u00a0expression in the hippocampus when compared with control rat brains. The level of acetylation sites in histone H2A, H3\u00a0and H4 was significantly decreased under hypobaric hypoxia exposure compared to the control rat's hippocampus. Additionally, inhibiting the HDAC family with sodium butyrate administration (1.2\u2009g/kg body weight) attenuated neurodegeneration and memory loss in hypobaric hypoxia-exposed rats. Moreover, histone acetylation increased at the promoter regions of brain-derived neurotrophic factor\u00a0(BDNF);\u00a0thereby its protein expression was enhanced significantly in hypobaric hypoxia exposed rats treated with HDAC inhibitor compared with hypoxic rats. Thus, BDNF expression upregulated cAMP-response element binding protein (CREB) phosphorylation by stimulation of PI3K/GSK3\u03b2/CREB axis, which counteracts hypobaric hypoxia-induced spatial memory impairment. In conclusion, these results suggested that sodium butyrate is a novel therapeutic agent for the treatment of spatial memory loss associated with hypobaric hypoxia, and also further studies are warranted to explore specific HDAC inhibitors in this condition."

However, the mechanisms still require further investigation. In this study, we found that the butanoate metabolism pathway exhibited significantly decreased and short chain fatty acid (SCFAs)-producing bacteria, especially butyrate-producing bacteria, were significantly decreased in fecal of neonatal hypoxic-ischemic brain damage (HIBD) rats. Surprisingly, Sodium butyrate (SB) treatment could ameliorate pathological damage both in the cerebral cortex and hippocampus and facilitate recovery of SCFAs-producing bacteria related to metabolic pathways in neonatal HIBD rats. Moreover, we found that in samples from SB treatment neonatal HIBD rats cortex with high levels of butyrate acid along with aberrant key crotonyl-CoA-producing enzymes ACADS levels were observed compared HIBD rats. We also demonstrated that a decrease in histone 3-lysine 9-crotonylation (H3K9cr) downregulated expression of the HIE-related neurotrophic genes Bdnf, Gdnf, Cdnf, and Manf in HIBD rats. Furthermore, SB restored H3K9cr binding to HIE-related neurotrophic genes. Collectively, our results indicate that SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression. This may be a novel microbiological approach for preventing and treating HIE."

Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique."

The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment.

In this study, we demonstrated that A. muciniphila administration improve cognitive deficits and reduce amyloid-beta (A\u03b2) deposition in APP/PS1 mice, a transgenic model of AD. Subsequently, it is revealed that A. muciniphila administration significantly alters gut microbiota diversity and composition. Mechanically, our metabolomics analysis of cecal contents indicates A. muciniphila administration increases short-chain fatty acids (SCFAs) derived from the intestinal microbiota, including butyric acid and acetic acid. Significantly, in APP/PS1 mice with the A. muciniphila administration, targeted metabolomics identify that the production of 62 metabolites are increased such as indole-3-acetic acid (IAA), tryptophan, acetic acid and cinnamic acid, as well as aconitic acid and threonine, et al.; the production of 28 metabolites are decreased such as isoleucine and N-acetylneuraminic acid (NANA) as well as ornithine and docosapentaenoic acid (DPA), et al. It is also identified by cytokine analysis of plasma that A. muciniphila administration reduces peripheral pro-inflammatory cytokines interleukin-6 (IL-6), IL-1\u03b2, IL-17 and tumor necrosis factor-alpha (TNF-\u03b1), et al., whereas it increases anti-inflammatory cytokines, such as IL-4, IL-10 and IL-22, et al. There is no any change of other cytokines, such as interferon-gamma (IFN-g), IL-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF), et al. Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators. At the same time, A. muciniphila administration improves cognitive deficits, alleviates neuroinflammation and A\u03b2 deposition via AhR/NF-\u03baB/NLRP3 signaling pathway in APP/PS1 mice. In summary, our findings suggest A. muciniphila is a promising approach for preventing AD progression by microbiota-gut-brain axis."

Roseburia intestinalis (R. intestinalis) is consistently reduced in PD; however, its functional contribution remains unknown. We performed two complementary mouse experiments using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model. In the primary intervention experiment, mice received live or heat-killed R. intestinalis, followed by behavioral assessments and multi-layer analyses, including immunofluorescence, western blotting, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, 16S rRNA sequencing, metabolomics, and transcriptomics. In a separate mechanistic experiment, subdiaphragmatic vagotomy was introduced to interrogate vagus-dependent gut-brain communication, with key behavioral and inflammatory endpoints assessed. Live R. intestinalis improved rotarod, pole, and grip strength performance and preserved tyrosine hydroxylase-positive neurons in the substantia nigra; however, these effects were not observed in the heat-killed group. Live R. intestinalis treatment also reduced glial reactivity, restored brain-derived neurotrophic factor expression, and maintained blood-brain barrier integrity. Systemically, R. intestinalis lowered serum lipopolysaccharide, tumor necrosis factor-\u03b1, and interleukin-6 levels; preserved colonic structure; and restored mucin-secreting goblet cell function. MPTP-induced dysbiosis was partially corrected. Metabolomic profiling revealed restoration of several acyl-carnitines and higher acetic acid levels. Transcriptomic analysis showed increased immediate early genes after MPTP, and the elevated c-Fos in the substantia nigra was partially normalized by R. intestinalis. Importantly, vagotomy abolished the central neuroprotective and anti-inflammatory effects but did not affect peripheral cytokine suppression, indicating both vagus-dependent and vagus-independent pathways. R. intestinalis supplementation alleviated motor impairments, reduced neuroinflammation, preserved dopaminergic neurons, and improved intestinal and metabolic alterations in mice with an MPTP-induced PD model. Its protective actions may involve both central and peripheral mechanisms, potentially including gut-brain communication pathways. R. intestinalis may be a promising candidate for microbiota-based strategies against PD."

Corylus heterophylla Fisch. male flower extract (CFE), a flavonoid-rich by-product of hazelnut processing, presents a promising yet unexplored neuroprotective candidate. This study investigated the preventive effects and mechanisms of CFE against HNF-induced cognitive decline. Methods: In the present study, mice were pretreated with CFE (200 mg/kg) before the Lipopolysaccharide (LPS) administration. Cognitive function, inflammation, core pathology, neuroplasticity, gut microbiota and serum metabolites were assessed. The chemical composition of CFE was analyzed by UHPLC-MS and its direct immunomodulatory effects were investigated in BV2 cells. Results: Behavioral assessments demonstrated significant therapeutic efficacy. This was evidenced by the recovery from hippocampal damage, accompanied by reduced levels of core pathological markers (A\u03b21-42, Tau, p-Tau (Ser404), GSK-3\u03b2), decreased expression of pro-inflammatory mediators including IL-33, elevated levels of neurotrophic factors (BDNF and MAP2), and attenuated abnormal activation of astrocytes and microglia.

This was evidenced by the recovery from hippocampal damage, accompanied by reduced levels of core pathological markers (A\u03b21-42, Tau, p-Tau (Ser404), GSK-3\u03b2), decreased expression of pro-inflammatory mediators including IL-33, elevated levels of neurotrophic factors (BDNF and MAP2), and attenuated abnormal activation of astrocytes and microglia. The 16S rRNA analysis confirmed that CFE ameliorated gut microbial dysbiosis. Notably, CFE significantly increased the relative abundance of Muribaculaceae and Lachnospiraceae, while significantly decreased Staphylococcus and Helicobacter. Metabolomics revealed enhanced levels of \u03b1-linolenic acid (ALA), serotonin (5-HT) and acetic acid, which correlated positively with Muribaculaceae and Lachnospiraceae. Phytochemical analysis identified luteolin and kaempferol as the predominant flavonoids in CFE. In BV2 cells, CFE, luteolin and kaempferol shifted microglial polarization from the M1 phenotype toward the M2 phenotype. Conclusions: CFE alleviated HNF-induced cognitive decline by regulating microbiota-gut-brain axis and microglial M1/M2 polarization."

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

Clinical observations have shown that Liqi Yangyin (LQYY) can effectively relieve symptoms of depression accompanied by constipation. However, whether LQYY exerts its effects through gut-brain crosstalk remains to be elucidated. A chronic unpredictable mild stress (CUMS) protocol was employed to establish a mouse model. H&E and Nissl staining were used to examine pathological changes in the prefrontal cortex (PFC) and colon. The ultrastructure of the intestinal barrier was observed via transmission electron microscopy, while the expression of the blood-brain barrier tight junction proteins was quantified by Western blotting (WB). ELISA quantified inflammatory factors and serotonin (5-HT) levels. Immunohistochemistry, immunofluorescence, and WB analyzed IBA-1 and Free fatty acid receptor 2 (FFAR2) expression levels. Gut microbiota composition was analyzed via 16S rDNA sequencing, and SCFAs levels were quantified using UHPLC-TSQ Altis Plus. Additionally, in vitro studies using BV-2 cells involved treatments with acetic acid (ACE) and an FFAR2 antagonist, after which the expression of relevant indicators was assessed. Our results demonstrated that LQYY significantly ameliorated CUMS-induced behavioral changes and improved intestinal motility. These effects were associated with the restoration of gut microbiota balance and an increase in ACE levels. LQYY increased FFAR2 expression, leading to reduced neuroinflammation and enhanced colonic 5-HT secretion. Furthermore, LQYY protected intestinal and blood-brain barrier integrity and improved neuronal morphology in the PFC. In vitro studies confirmed that ACE suppresses microglial inflammation through upregulating FFAR2 expression, an effect that was attenuated by the FFAR2 inhibitor GLPG0974. These findings suggest that LQYY modulates the gut-brain axis through ACE/FFAR2, offering a promising therapeutic approach for depression and constipation."

Their analysis highlights lactate's expanding role beyond a metabolic byproduct, emphasizing its functions in cellular signaling, antioxidant defense, and neuroprotection. Our study demonstrated that NaL improved acid-base balance without adverse effects, likely through lactate's conversion to bicarbonate and potential support for mitochondrial function. The commentary further explores NaL's translational relevance in neonatal hypoxia-ischemia (NHI), where lactate may serve as a key neuroenergetic substrate and modulate inflammation and gene expression. While the Rice-Vannucci model has limitations, it remains valuable for long-term studies, as shown in our prior work. We agree that larger animal models offer enhanced physiological relevance but face practical constraints. Future research should compare NaL with sodium acetate (NaA), a standard in neonatal care, to assess relative benefits in correcting acidosis and supporting neurodevelopment. We support the call for randomized, multicenter studies with long-term follow-up to fully evaluate NaL's therapeutic potential in preterm and at-risk neonates. IMPACT: L-lactate is a key component of the astrocyte-neuron lactate shuttle, supporting brain energy metabolism. Ibrahim et al. suggest sodium L-lactate as an alternative maintenance fluid for preterm newborns. L-lactate should not be regarded merely as a simple fluid replacement. L-lactate acts as a signaling molecule, impacting cellular metabolism and brain development. Additional research is required to assess the potential benefits and safety of sodium L-lactate in newborns."

This therapy involves the use of Myristica fragrans Houtt. and Carum carvi L., along with fomentation and massage, and has shown significant clinical effects. However, the mechanism of how Huoermai therapy treats plateau insomnia needs further clarification. This study aimed to investigate the mechanism of action of Huoermai essential oil (HEO) in treating plateau insomnia, focusing on the cAMP/CREB/BDNF/GABAergic pathway. The major components of Huoermai essential oil were identified by Gas chromatography-mass spectrometry (GC-MS) for subsequent network pharmacology analysis. Proteomics techniques were employed to pinpoint disparities in brain tissue protein expression in a mouse model of plateau insomnia following Huoermai therapy administration, in conjunction with network pharmacology to forecast pathways related to hypoxia and insomnia. Plateau insomnia mouse model was established and the therapeutic impact of Huoermai essential oil was evaluated. Hematoxylin & Eosin staining(HE) was conducted to observe pathological damage to the cortex, hippocampus, thalamus and hypothalamus structures. Changes in serotonin (5-HT), melatonin (MT), adenosine (AD), cyclic adenosine monophosphate (cAMP) and malondialdehyde (MDA) levels in mouse brain tissue were gauged through enzyme-linked immunosorbent assay (ELISA) to assess sleep status and oxidative stress levels in mice. Molecular docking was employed to anticipate the target binding energy of Huoermai essential oil constituents. ELISA and Western Blot (WB) were used to ascertain the expression of cAMP/CREB/BDNF/GABAergic pathway. The results indicated that HEO positively impacted intermittent hypobaric hypoxia-induced plateau insomnia in mice. Histological examination results showed that HEO ameliorated neuronal damage in specific regions of the brain affected by plateau insomnia, such as the cortex, hippocampus, thalamus, and hypothalamus. Through GC-MS analysis, 56 volatile oil components were identified. Subsequently, a combined network pharmacology and proteomics analyses led to selecting the cAMP/CREB/BDNF/GABAergic pathway for further study. ELISA experiments demonstrated that HEO treatment increased GABA and MT levels while significantly reducing 5-HT and adenosine levels in brain tissue of mice with plateau insomnia. WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress. Moreover, molecular docking results showed strong binding affinity of all pharmacological components to their targets and proteins in the brain. These results indicate that HEO significantly prolongs sleep duration in plateau insomniac mice and treats plateau insomnia by modulating levels of sleep-related regulators, modulating the cAMP pathway, increasing GABA receptor expression, and improving neuronal survival and anti-apoptosis."

It was aimed to elucidate the potential therapeutic effect of estrogen receptor agonists on NEC-induced intestinal and brain injury in rats. Sprague-Dawley pups of both sexes were separated from their mothers at postnatal 5th d. Feeding with formula along with a single session of hypoxia was applied to induce NEC, while control pups were kept with their mothers. The NEC rats received either vehicle, estrogen receptor \u03b1 (ER\u03b1) agonist propyl pyrazole triol (1\u00a0mg/kg/day), ER\u03b2 agonist diarylpropionitrile (1\u00a0mg/kg/day), or 17\u03b2-estradiol (1\u00a0mg/kg/day) during maternal separation. All pups were decapitated on postnatal 9th d to collect intestinal and brain tissue samples. Elevation in proinflammatory cytokines, apoptosis, and microscopically and biochemically evident oxidative injury in both the intestinal and brain tissues were observed in NEC-induced pups. In both the intestinal and brain tissues, nerve growth factor and brain-derived neurotrophic factor protein levels were depleted, expressions of both the ESR1 and ESR2 genes were downregulated, while treatment with 17\u03b2-estradiol or ER agonists alleviated extent of oxidative injury of the intestines and brain tissue, upregulated nerve growth factor, brain-derived neurotrophic factor, and ER gene expressions, abolished NEC-induced decrease in claudin-3 expression, increased the survival rates, improved the clinical states of the survived pups at varying degrees. Activation of estrogen signaling by receptor agonists alleviated NEC-induced intestinal and cerebral injury, implicating that estrogen agonists could be regarded as promising preventive/therapeutic agents for NEC."

Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and Amchi system of medicine. These are rich sources of diverse bioactive metabolites having prophylactic and therapeutic uses against a wide array of neurodegenerative diseases. The objective of this study was to elucidate the prophylactic and neuroprotective efficacy of formulated phytococktail (PC) against simulated HH-induced neurodegeneration in male Sprague Dawley (SD) rats. Materials and Methods: A PC containing H. rhamnoides fruit pulp, P. armeniaca fruit pulp, and R. imbricata dry root extract (100:50:1) was formulated. The neuroprotective efficacy of PC was evaluated in male SD rats following exposure to 7 day HH at simulated altitude (25,000 ft, 282\u2009mm Hg). Rats were divided into four groups viz., normoxia group (NOR), normoxic group treated with PC (NORPC), 7 day hypoxic group treated with vehicle (7DH), and 7 day hypoxic group treated with PC (7DHPC). Memory impairment and neuromorphological alterations were measured. Targeted protein expression was analyzed by immunoblotting study. Results: PC supplementation significantly reduced the oxidative stress markers during exposure to HH. Spatial memory impairment by HH was significantly ameliorated by PC. HH-induced augmented pyknosis, decreased dendritic arborization, and increased Hoechst-positive neurons in hippocampal CA3 region were significantly ameliorated by PC. Immunoblotting study showed upregulation of BDNF and TrkB expression by PC. PC also prevented the hippocampal neurodegeneration by activating the PI3K/AKT signaling pathway, which leads to GSK-3\u03b2 inactivation by its phosphorylation and alleviation of hippocampal Caspase3 expression leading to inhibition of apoptotic neuronal cell death. Conclusion: The present study advocates the potential role of PC as an effective neuroprotective supplement in preventing HH-induced neurodegeneration. Activation of the PI3K/Akt pathway through BDNF/TrkB interaction following PC supplementation after exposure to HH inhibits hippocampal neuronal apoptosis and memory impairment."

However, the mechanisms still require further investigation. In this study, we found that the butanoate metabolism pathway exhibited significantly decreased and short chain fatty acid (SCFAs)-producing bacteria, especially butyrate-producing bacteria, were significantly decreased in fecal of neonatal hypoxic-ischemic brain damage (HIBD) rats. Surprisingly, Sodium butyrate (SB) treatment could ameliorate pathological damage both in the cerebral cortex and hippocampus and facilitate recovery of SCFAs-producing bacteria related to metabolic pathways in neonatal HIBD rats. Moreover, we found that in samples from SB treatment neonatal HIBD rats cortex with high levels of butyrate acid along with aberrant key crotonyl-CoA-producing enzymes ACADS levels were observed compared HIBD rats. We also demonstrated that a decrease in histone 3-lysine 9-crotonylation (H3K9cr) downregulated expression of the HIE-related neurotrophic genes Bdnf, Gdnf, Cdnf, and Manf in HIBD rats. Furthermore, SB restored H3K9cr binding to HIE-related neurotrophic genes. Collectively, our results indicate that SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression. This may be a novel microbiological approach for preventing and treating HIE."

Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique."

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.

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.

Casticin, a compound purified from the Chinese herb Viticis Fructus, has been proved effective in preventing inflammation and fibrosis in previous studies. However, the effect of casticin on synovial fibrosis in KOA is not clear.

The MIA-induced knee osteoarthritis model and lipopolysaccharide (LPS) stimulated primary synovial fibroblasts inflammation model were established. Pathological and morphological changes in synovial tissue were observed by H&E and sirius red staining.

However, the downstream mechanisms underlying the TRPM7-mediated processes in physiology and pathophysiology remain unclear. In this study, we employed a mouse model of hypoxic-ischemic brain cell death which mimics the pathophysiology of hypoxic-ischemic encephalopathy (HIE). HIE is a major public health issue and an important cause of neonatal deaths worldwide; however, the available treatments for HIE remain limited. Its survivors face life-long neurological challenges including mental retardation, cerebral palsy, epilepsy and seizure disorders, motor impairments, and visual and auditory impairments. Through a proteomic analysis, we identified calcium/calmodulin-dependent protein kinase II (CaMKII) and phosphatase calcineurin as potential mediators of cell death downstream from TRPM7 activation. Further analysis revealed that TRPM7 mediates cell death through CaMKII, calmodulin, calcineurin, p38, and cofilin cascade. In vivo, we found a significant reduction of brain injury and improvement of short- and long-term functional outcomes after HI after administration of specific TRPM7 blocker waixenicin A.

Increasing evidence implicates neuroinflammation, oxidative stress, and dysregulation of neurotrophic and neurotransmitter systems as central mechanisms driving these conditions. Flavonoids, a structurally diverse class of plant-derived polyphenolic compounds abundantly found in fruits, vegetables, tea, and other dietary sources, have emerged as promising modulators of these pathophysiological pathways. This narrative review synthesizes current preclinical and clinical evidence on the role of flavonoids and related natural compounds in modulating neuroinflammation and affective disorders. We describe the major flavonoid subclasses-flavones, flavonols, isoflavones, anthocyanins, flavanones, and flavan-3-ols-and analyze their mechanisms of action, including inhibition of the NF-\u03baB/NLRP3 axis, reduction in pro-inflammatory cytokines, attenuation of oxidative stress via Nrf2 pathway activation, modulation of monoaminergic and GABAergic neurotransmission, promotion of Brain-Derived Neurotrophic Factor (BDNF)-mediated neuroplasticity, and regulation of the microbiota-gut-brain axis. Preclinical studies consistently demonstrate anxiolytic and antidepressant effects for compounds such as quercetin, luteolin, apigenin, and chrysin; however, clinical evidence remains limited and methodologically heterogeneous. Future research should prioritize bioavailability-enhanced formulations, standardized clinical trials, and biomarker-guided stratification to fully establish the therapeutic potential of flavonoids in affective disorders."

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain."

But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention."

This heterogeneity makes altitude biologically informative for stroke research, but it does not justify treating natural altitude exposure as a single protective or harmful state. In this structured narrative review, we searched and organized the literature to ask which altitude-associated hypoxic cues resemble or reveal mechanisms compatible with cerebral ischemic tolerance, and what level of evidence supports that claim. We separate long-term adaptation, short-term acclimatization, chronic or excessive environmental hypoxia, and experimental hypoxic conditioning; define direct, supportive, and indirect evidence tiers; and integrate neurovascular-unit biology with multi-omics and stroke pathophysiology. Experimental hypoxic preconditioning remains the clearest direct evidence that a defined sublethal hypoxic stimulus can induce a time-limited tolerant state. In contrast, human high-altitude epidemiology, physiology, and genetics mainly constrain the clinical context and nominate candidate pathways rather than prove stroke-specific protection. We also emphasize that chronic hypoxia can be maladaptive through endothelial dysfunction, oxidative stress, erythrocytosis, thrombogenicity, blood-brain barrier impairment, and microvascular injury. Across neurovascular-unit cell types, a transparent evidence-weighting framework prioritizes endothelial biology because of its direct connection to BBB stability, effective reperfusion, hemorrhagic transformation risk, and no-reflow, while neurons, astrocytes, microglia, oligodendrocyte-lineage cells, and pericytes require different degrees of causal and human validation. We argue that the most productive path forward is not to label altitude as protective, but to use altitude-related biology to prioritize testable, stroke-facing hypotheses regarding BBB stability, microvascular patency, metabolic support, inflammatory thresholds, white-matter resilience, and biomarker-defined conditioning windows."

In the d-galactose-induced aging mice model, BNMS2 effectively improved cognitive dysfunction and outperformed sodium butyrate and high-amylose maize starch. BNMS2 ameliorated cognitive behavior and brain histopathology, decreased GFAP, IBA-1, A\u03b2, AChE, MDA, IL-6, IL-1\u03b2, and TNF-\u03b1 levels, and increased BDNF, PSD-5, GSH-Px, and SOD levels to mitigate neuronal damage, oxidative stress, and inflammation.

Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis. Consequently, our findings indicate that Blautia massiliensis enhances cognitive function whereas Blautia faecis impairs it, and we speculate that differential acetate production may contribute to these opposing effects."

This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications."

The latter has been studied by engaging nociceptive fibers using electrical stimulation or capsaicin caudal to a thoracic SCI. Nociceptive stimulation 1\u202fday after SCI increases hemorrhage, amplifying secondary tissue loss. Noxious stimulation also promotes hemorrhage after a traumatic brain injury (TBI). A common form of polytrauma after SCI involves a TBI. The current study examines whether a concurrent TBI promotes hemorrhage after SCI. This also allowed us to evaluate whether a concurrent SCI promotes brain hemorrhage after TBI. Animals received a thoracic SCI and a concurrent brain surgery (anesthesia alone, craniectomy, or TBI). Other animals received a TBI to the frontal region and a concurrent spinal surgery (anesthesia alone, laminectomy, or SCI). Tissue was collected 24\u202fh later, sectioned, and the extent of brain/spinal cord hemorrhage was quantified. Sham controls were included to verify a remote injury (SCI/TBI) does not induce hemorrhage in the absence of local neural damage. A concurrent TBI with a SCI amplified hemorrhage in the spinal cord. A craniectomy had an intermediate effect on hemorrhage. Additionally, concurrent SCI with a TBI increased hemorrhage in the brain with a more modest effect. The results provide a link between hemorrhage development and concurrent neural injuries, with greater hemorrhage observed after SCI in animals with a concurrent TBI. SCI modestly impacted hemorrhage after TBI. These results provide a basis to further investigate the mechanisms responsible for interactions between multiple neurotraumatic injuries."

Although glial cells are essential for maintaining neural homeostasis under stress, how specific glial subtypes remodel metabolism to promote hypoxia tolerance remains poorly understood. Here, we identify a Notch-dependent lipid metabolic program in excitatory amino acid transporter 1 (Eaat1)-positive glia that supports hypoxia adaptation in the developing Drosophila larval brain. Using stimulated Raman scattering (SRS) microscopy combined with deuterium-labeled metabolic probes, we visualized substrate-specific metabolic activity in vivo at subcellular resolution. In control, non-adapted flies, we found that acute hypoxia markedly increased de novo lipogenesis in Eaat1-positive glia. In flies adapted to chronic hypoxia, Eaat1-positive glia exhibited a pre-programmed metabolic shift, characterized by reduced glucose-derived lipogenesis and enhanced acetate-derived lipid synthesis. Constitutive activation of Notch signaling in Eaat1-positive glia was sufficient to phenocopy this acetate-favored lipogenic state, suggesting that Notch promotes metabolic plasticity under oxygen-limited conditions. To define the transcriptional programs associated with this response, we performed single-nucleus RNA sequencing (snRNA-seq) of the developing Drosophila central nervous system and mapped Eaat-1expressing cell populations across hypoxia and Notch activation. Notch activation reshaped hypoxia-associated transcriptional responses and counteracted metabolic suppression caused by low oxygen. Together, our findings identify Eaat1-positiveglia as a metabolically adaptive glial population and reveal a conserved Notch-regulated mechanism that rewires lipid metabolism to support hypoxia tolerance in the developing brain. These results provide insight into glial metabolic strategies that may be relevant to hypoxia-associated neurological conditions, including neonatal hypoxic-ischemic brain injury and ischemic stroke."

Total correct responses, mean cluster size and number of switches were analysed. Compared with controls, individuals with mTBI produced fewer 'S' words (z = 2.66, P = 0.007, r = 0.45) and semantic switches (z = 2.45, P = 0.015, r = 0.41).

Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke."

Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity."

Acupuncture, a multi-target holistic non-pharmacological intervention, shows unique clinical advantages. This review provides the first systematic synthesis of the central neurobiological mechanisms underlying acupuncture's therapeutic effects on PSD. The identified mechanisms include promoting neuroplasticity via the BDNF/TrkB pathway and rebalancing neurotransmitter systems (monoamines and glutamate/GABA).

With limited disease-modifying pharmacotherapies, lifestyle interventions have emerged as compelling, evidence-based avenues for prevention and early management. This review integrates mechanistic, translational, and clinical insights on major modifiable behaviours, physical activity, diet, intermittent fasting, sleep regulation, and gut-microbiome-based approaches that collectively shape cognitive ageing. Aerobic, anaerobic, and resistance exercises exert neuroprotective effects by activating BDNF-TrkB signalling, enhancing hippocampal neurogenesis, improving synaptic plasticity, and stimulating peripheral myokines (CTSB, IGF-1, GPLD1) that cross the blood-brain barrier to support neuronal resilience. Dietary interventions such as the Mediterranean, Mediterranean- DASH Intervention for Neurodegenerative Delay (MIND), and ketogenic diets mitigate AD pathology by reducing oxidative stress, inhibiting A\u03b2 deposition, improving mitochondrial efficiency, and modulating APOE4-linked metabolic vulnerability. Intermittent fasting induces a metabolic shift toward ketone utilisation, activates autophagy pathways (AMPK, SIRT3, Nrf2), remodels the gut microbiome, and promotes angiogenesis through GDF11 signalling. The gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation, and enhanced neuronal survival. Meanwhile, sleep quality, particularly slow-wave sleep, optimises glymphatic clearance and prevents the pathological accumulation of A\u03b2 and tau. Collectively, the evidence suggests that multidomain lifestyle approaches offer synergistic benefits that exceed those of individual interventions, representing promising strategies for delaying cognitive decline. However, gaps remain regarding dose-response relationships, personalised protocols for APOE4 carriers, and long-term validation in diverse populations. Strengthening these research directions is crucial for integrating lifestyle medicine into preventive neurology and public health frameworks."

However, pharmacological interventions that precisely modulate the gut microbiota in DRE have not yet been fully explored. This review aims to propose a systematic hypothesis that Dipeptidyl peptidase-4 inhibitors (DPP-4is) may alleviate peripheral and central pathological damage by regulating the \"gut microbiota-short-chain fatty acids (SCFAs) -glucagon-like peptide-1 (GLP-1) axis\", thereby reducing susceptibility to DRE. Existing studies indicate that: (1)DPP-4is possess neuroprotective effects in experimental epilepsy models, partly by enhancing endogenous GLP-1 signaling. (2)DPP-4is have been reported to modulate gut microbiota composition and increase the abundance of SCFA-producing bacteria in metabolic diseases. (3)SCFAs can promote GLP-1 secretion by activating free fatty acid receptors (FFAR2/3) and improve intestinal barrier function and inflammatory status in metabolic and neurodegeneration disease. However, it remains unclear whether this pathway mediates the effects of DPP-4is in epilepsy. (4)Enhanced peripheral GLP-1 signaling can further influence central nervous system homeostasis, including enhancing inhibitory synaptic transmission, attenuating neuroinflammation, oxidative stress, and inhibiting neuronal apoptosis, thereby reducing susceptibility to seizures. By integrating cross-contextual evidence, we propose that DPP-4is may exert protective effects on DRE through gut microbiota-SCFAs-GLP-1 axis."

Increasing evidence implicates neuroinflammation, oxidative stress, and dysregulation of neurotrophic and neurotransmitter systems as central mechanisms driving these conditions. Flavonoids, a structurally diverse class of plant-derived polyphenolic compounds abundantly found in fruits, vegetables, tea, and other dietary sources, have emerged as promising modulators of these pathophysiological pathways. This narrative review synthesizes current preclinical and clinical evidence on the role of flavonoids and related natural compounds in modulating neuroinflammation and affective disorders. We describe the major flavonoid subclasses-flavones, flavonols, isoflavones, anthocyanins, flavanones, and flavan-3-ols-and analyze their mechanisms of action, including inhibition of the NF-\u03baB/NLRP3 axis, reduction in pro-inflammatory cytokines, attenuation of oxidative stress via Nrf2 pathway activation, modulation of monoaminergic and GABAergic neurotransmission, promotion of Brain-Derived Neurotrophic Factor (BDNF)-mediated neuroplasticity, and regulation of the microbiota-gut-brain axis. Preclinical studies consistently demonstrate anxiolytic and antidepressant effects for compounds such as quercetin, luteolin, apigenin, and chrysin; however, clinical evidence remains limited and methodologically heterogeneous. Future research should prioritize bioavailability-enhanced formulations, standardized clinical trials, and biomarker-guided stratification to fully establish the therapeutic potential of flavonoids in affective disorders."

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain."

But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention."

This heterogeneity makes altitude biologically informative for stroke research, but it does not justify treating natural altitude exposure as a single protective or harmful state. In this structured narrative review, we searched and organized the literature to ask which altitude-associated hypoxic cues resemble or reveal mechanisms compatible with cerebral ischemic tolerance, and what level of evidence supports that claim. We separate long-term adaptation, short-term acclimatization, chronic or excessive environmental hypoxia, and experimental hypoxic conditioning; define direct, supportive, and indirect evidence tiers; and integrate neurovascular-unit biology with multi-omics and stroke pathophysiology. Experimental hypoxic preconditioning remains the clearest direct evidence that a defined sublethal hypoxic stimulus can induce a time-limited tolerant state. In contrast, human high-altitude epidemiology, physiology, and genetics mainly constrain the clinical context and nominate candidate pathways rather than prove stroke-specific protection. We also emphasize that chronic hypoxia can be maladaptive through endothelial dysfunction, oxidative stress, erythrocytosis, thrombogenicity, blood-brain barrier impairment, and microvascular injury. Across neurovascular-unit cell types, a transparent evidence-weighting framework prioritizes endothelial biology because of its direct connection to BBB stability, effective reperfusion, hemorrhagic transformation risk, and no-reflow, while neurons, astrocytes, microglia, oligodendrocyte-lineage cells, and pericytes require different degrees of causal and human validation. We argue that the most productive path forward is not to label altitude as protective, but to use altitude-related biology to prioritize testable, stroke-facing hypotheses regarding BBB stability, microvascular patency, metabolic support, inflammatory thresholds, white-matter resilience, and biomarker-defined conditioning windows."

Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis.

This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications."

The latter has been studied by engaging nociceptive fibers using electrical stimulation or capsaicin caudal to a thoracic SCI. Nociceptive stimulation 1\u202fday after SCI increases hemorrhage, amplifying secondary tissue loss. Noxious stimulation also promotes hemorrhage after a traumatic brain injury (TBI). A common form of polytrauma after SCI involves a TBI. The current study examines whether a concurrent TBI promotes hemorrhage after SCI. This also allowed us to evaluate whether a concurrent SCI promotes brain hemorrhage after TBI. Animals received a thoracic SCI and a concurrent brain surgery (anesthesia alone, craniectomy, or TBI). Other animals received a TBI to the frontal region and a concurrent spinal surgery (anesthesia alone, laminectomy, or SCI). Tissue was collected 24\u202fh later, sectioned, and the extent of brain/spinal cord hemorrhage was quantified. Sham controls were included to verify a remote injury (SCI/TBI) does not induce hemorrhage in the absence of local neural damage. A concurrent TBI with a SCI amplified hemorrhage in the spinal cord. A craniectomy had an intermediate effect on hemorrhage. Additionally, concurrent SCI with a TBI increased hemorrhage in the brain with a more modest effect. The results provide a link between hemorrhage development and concurrent neural injuries, with greater hemorrhage observed after SCI in animals with a concurrent TBI. SCI modestly impacted hemorrhage after TBI. These results provide a basis to further investigate the mechanisms responsible for interactions between multiple neurotraumatic injuries."

Although glial cells are essential for maintaining neural homeostasis under stress, how specific glial subtypes remodel metabolism to promote hypoxia tolerance remains poorly understood. Here, we identify a Notch-dependent lipid metabolic program in excitatory amino acid transporter 1 (Eaat1)-positive glia that supports hypoxia adaptation in the developing Drosophila larval brain. Using stimulated Raman scattering (SRS) microscopy combined with deuterium-labeled metabolic probes, we visualized substrate-specific metabolic activity in vivo at subcellular resolution. In control, non-adapted flies, we found that acute hypoxia markedly increased de novo lipogenesis in Eaat1-positive glia. In flies adapted to chronic hypoxia, Eaat1-positive glia exhibited a pre-programmed metabolic shift, characterized by reduced glucose-derived lipogenesis and enhanced acetate-derived lipid synthesis. Constitutive activation of Notch signaling in Eaat1-positive glia was sufficient to phenocopy this acetate-favored lipogenic state, suggesting that Notch promotes metabolic plasticity under oxygen-limited conditions. To define the transcriptional programs associated with this response, we performed single-nucleus RNA sequencing (snRNA-seq) of the developing Drosophila central nervous system and mapped Eaat-1expressing cell populations across hypoxia and Notch activation. Notch activation reshaped hypoxia-associated transcriptional responses and counteracted metabolic suppression caused by low oxygen. Together, our findings identify Eaat1-positiveglia as a metabolically adaptive glial population and reveal a conserved Notch-regulated mechanism that rewires lipid metabolism to support hypoxia tolerance in the developing brain. These results provide insight into glial metabolic strategies that may be relevant to hypoxia-associated neurological conditions, including neonatal hypoxic-ischemic brain injury and ischemic stroke."

No group differences were observed for phonemic switching. Findings indicate subtle reductions in cognitive flexibility and verbal productivity in individuals with chronic mTBI. Clustering and switching analyses in verbal fluency tasks may detect subtle, executive deficits in individuals with chronic mTBI that are not captured by total word count alone. These findings support the feasibility of subcomponent verbal fluency measures as sensitive tools for long-term mTBI assessment and monitoring."

Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke."

Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity."

With limited disease-modifying pharmacotherapies, lifestyle interventions have emerged as compelling, evidence-based avenues for prevention and early management. This review integrates mechanistic, translational, and clinical insights on major modifiable behaviours, physical activity, diet, intermittent fasting, sleep regulation, and gut-microbiome-based approaches that collectively shape cognitive ageing. Aerobic, anaerobic, and resistance exercises exert neuroprotective effects by activating BDNF-TrkB signalling, enhancing hippocampal neurogenesis, improving synaptic plasticity, and stimulating peripheral myokines (CTSB, IGF-1, GPLD1) that cross the blood-brain barrier to support neuronal resilience. Dietary interventions such as the Mediterranean, Mediterranean- DASH Intervention for Neurodegenerative Delay (MIND), and ketogenic diets mitigate AD pathology by reducing oxidative stress, inhibiting A\u03b2 deposition, improving mitochondrial efficiency, and modulating APOE4-linked metabolic vulnerability. Intermittent fasting induces a metabolic shift toward ketone utilisation, activates autophagy pathways (AMPK, SIRT3, Nrf2), remodels the gut microbiome, and promotes angiogenesis through GDF11 signalling. The gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation, and enhanced neuronal survival. Meanwhile, sleep quality, particularly slow-wave sleep, optimises glymphatic clearance and prevents the pathological accumulation of A\u03b2 and tau. Collectively, the evidence suggests that multidomain lifestyle approaches offer synergistic benefits that exceed those of individual interventions, representing promising strategies for delaying cognitive decline. However, gaps remain regarding dose-response relationships, personalised protocols for APOE4 carriers, and long-term validation in diverse populations. Strengthening these research directions is crucial for integrating lifestyle medicine into preventive neurology and public health frameworks."

However, pharmacological interventions that precisely modulate the gut microbiota in DRE have not yet been fully explored. This review aims to propose a systematic hypothesis that Dipeptidyl peptidase-4 inhibitors (DPP-4is) may alleviate peripheral and central pathological damage by regulating the \"gut microbiota-short-chain fatty acids (SCFAs) -glucagon-like peptide-1 (GLP-1) axis\", thereby reducing susceptibility to DRE. Existing studies indicate that: (1)DPP-4is possess neuroprotective effects in experimental epilepsy models, partly by enhancing endogenous GLP-1 signaling. (2)DPP-4is have been reported to modulate gut microbiota composition and increase the abundance of SCFA-producing bacteria in metabolic diseases. (3)SCFAs can promote GLP-1 secretion by activating free fatty acid receptors (FFAR2/3) and improve intestinal barrier function and inflammatory status in metabolic and neurodegeneration disease. However, it remains unclear whether this pathway mediates the effects of DPP-4is in epilepsy. (4)Enhanced peripheral GLP-1 signaling can further influence central nervous system homeostasis, including enhancing inhibitory synaptic transmission, attenuating neuroinflammation, oxidative stress, and inhibiting neuronal apoptosis, thereby reducing susceptibility to seizures. By integrating cross-contextual evidence, we propose that DPP-4is may exert protective effects on DRE through gut microbiota-SCFAs-GLP-1 axis."

This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice. It reshaped gut microbial structures, enriched beneficial bacteria taxa such as Dubosiella, [Eubacterium]_coprostanoligenes_group, and Allobaculum, and increased SCFA levels. FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance. In addition, FDO upregulated BDNF, PSD-95, and SYN expression and reduced corticosterone (CORT) levels. Compared with DO, FDO showed more pronounced regulatory effects. Correlation analysis suggested that 5-HT may link gut microbial metabolites, inflammation, and synaptic plasticity. In summary, these findings support FDO as a potential GBA-targeted functional food for SD-related depressive-like behaviors."

Microbiome-derived metabolites have been increasingly associated with disease onset, progression, and therapeutic targets in neurodegenerative disorders. Exploring the diagnostic and therapeutic implications of gut microbiome-derived biomarkers is critical to advancing our understanding and management of neurodegeneration. We systematically reviewed both clinical and preclinical studies published from 2010 to 2025. Studies examining gut microbiota composition, microbial-derived metabolites, or therapeutic interventions targeting the gut microbiome were included. Identification of gut microbiome alterations, discovery of microbial or metabolite-based biomarkers, association with disease onset or progression, and/or therapeutic effects on cognitive, neurological, or inflammatory outcomes were evaluated. Short-chain fatty acids(SCFAs) such as butyrate and acetate were found to be noninvasive biomarkers in patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and Parkinson's disease (PD). Lower SCFA levels correlated with cognitive decline. Diagnostic accuracy improved when SCFA combinations were used, with AUCs ranging from 0.75 to 0.87. Trimethylamine N-oxide(TMAO) levels showed inconsistent associations, with both elevated and reduced levels linked to disease risk. Therapeutic approaches targeting gut microbiota, including probiotics, prebiotics, dietary changes, and fecal microbiota transplantation, demonstrated cognitive benefits and modulation of gut-brain signaling pathways. Overall, gut-derived biomarkers offer a promising avenue for early diagnosis and novel therapeutic approaches in AD and PD, while acknowledging that evidence in other neurodegenerative diseases remains limited through modulation of the gut-brain axis."

To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting. Treatment with BC99 was associated with alleviation of CUMS-induced depressive-like behaviors, increased butyrate levels, reduced neuroinflammation (IL-1\u03b2, IL-6, LPS, and IL-4), and restored hippocampal BDNF levels. BC99 also enriched butyrate-producing bacterial taxa (e.g., Lactobacillus, Bifidobacterium, Faecalibaculum) and normalized tryptophan and sphingolipid metabolism. Notably, sodium butyrate alone recapitulated several of the behavioral and anti-inflammatory effects observed with BC99 and, as shown by Western blot, partially restored hippocampal BDNF/TrkB/CREB signaling, which was impaired in CUMS rats. Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression."

Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the \"Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Function\" axis. Consistent physical exercise alters the gut microbiota, enhancing Short-Chain Fatty Acid (SCFA)-producing populations, which is associated with markedly elevated bioavailability of key metabolites (acetate, propionate, and butyrate). Rather than detailing exhaustive molecular pathways here, we emphasize that these SCFAs facilitate gut-brain communication through multiple synergistic routes, including receptor-mediated neuroendocrine signaling, epigenetic modulation of neuroplasticity, and the attenuation of systemic neuroinflammation. Current human observational and interventional data strongly support an associative link between exercise-induced SCFA fluctuations and improved mental health outcomes. Crucially, we propose the novel \"Exercise \u00d7 Fiber Synergy\" hypothesis: exercise primes the intestinal ecological niche for efficient substrate-utilizing bacteria, while adequate fermentable dietary fiber provides the necessary raw materials. Synergistically, this combination optimizes SCFA production to maximize cognitive and emotional benefits. To transition this framework into clinical practice, future research must prioritize 2 \u00d7 2 factorial designs (Exercise \u00d7 Fiber) with dynamic kinetic measurements, paving the way for microbial phenotype-oriented precision exercise and personalized nutritional interventions to enhance public mental health."

Beans (Phaseolus vulgaris) are rich in non-digestible carbohydrates and polyphenols, but whether kidney bean varieties differing in seed coat colour exert distinct effects on inflammation in obesity remains unclear. Objective: To determine whether supplementation of an obesogenic high-fat (HF) diet with white or dark red kidney beans modulates gut microbiota, SCFAs, and intestinal, systemic, and neuroinflammatory outcomes. Methods: Male C57Bl/6N mice (n = 12/group) were fed a basal diet (BD; modified AIN-93G), an HF diet (60% kcal from fat), or an HF diet supplemented with 15% cooked white (HF + WK) or dark red kidney beans (HF + DK) for nine weeks. Outcomes included cecal microbiota composition, predicted KEGG pathways with taxon contributors mapped with BURRITO (a tool for linking predicted microbial functions to contributing taxa), and SCFA-related pathways; cecal and fecal SCFA concentrations; colon histomorphometry and expression of gut barrier junction and inflammatory genes; serum cytokines and adipose hormones; and hippocampal inflammatory and barrier genes. Results: Mice consuming bean-supplemented HF diets had higher microbial diversity, enrichment of SCFA-producing taxa (Prevotella, Lactobacillus, Muribaculaceae), and lower obesity-associated genera versus HF alone (Mucispirillum, rc4-4). Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase in both bean groups versus HF and BD, and butyrate kinase in HF + DK versus BD. Bean supplementation attenuated HF-induced reduction of goblet cells and systemic interleukin (IL)-10. The HF + DK group had lower colonic tumour necrosis factor (TNF)-\u03b1 and partially attenuated hippocampal IL-6. SCFAs were inversely associated with systemic and neuroinflammatory markers in HF + DK mice. Conclusions: Kidney bean supplementation mitigated HF diet-induced intestinal, systemic, and neuroinflammatory disturbances in male mice, with microbiota and SCFA modulation. Further, dark red beans exerted stronger anti-inflammatory effects, highlighting the role of seed coat colour in bean-mediated obesity outcomes."

Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium longum 1714 have been associated with neuroactive effects, yet the molecular mechanisms linking microbial genomic potential to host neuronal responses remain poorly defined. This study aimed to integrate microbial genomics, neurotranscriptomics, and in vitro validation to unravel the neuromodulatory effects of L. rhamnosus GG and B. longum 1714. Whole-genome functional annotation, metabolic pathway prediction, and biosynthetic gene cluster analysis were performed to identify neuroactive potential. Neuronal RNA-seq datasets (n = 3 biological replicates per condition) were analyzed using differential expression, WGCNA, and GSEA to capture transcriptomic responses. Multi-omics integration (CCA, DIABLO, SPIEC-EASI) linked microbial pathways with neuronal gene modules. In vitro assays using SH-SY5Y and iPSC-derived neurons validated predictions through measurements of cell viability, oxidative stress, neurotransmitter release (ELISA), qPCR of synaptic and inflammatory genes, and extracellular vesicle characterization including EV transcript profiling. Genomic analysis revealed that L. rhamnosus GG was enriched in \u03b3-aminobutyric acid (GABA) and SCFA pathways, while B. longum 1714 carried tryptophan-indole metabolism genes. Transcriptomic profiling demonstrated upregulation of synaptic genes (BDNF, SYN1), showed upregulation of synaptic genes (BDNF, SYN1), serotonergic transporters (SLC6A4, TPH2), and suppression of inflammatory mediators (IL-6, TNF-\u03b1). Integration analyses identified two major subnetworks: a \"neurotransmission module\" driven by L. rhamnosus GG and a \"serotonin-immune module\" driven by B. longum 1714. In vitro validation confirmed increased GABA (1.7-fold) and serotonin (1.5-fold) release, reduced ROS (-18 to -22%), and EV transcript enrichment for synaptic and anti-inflammatory markers. This multi-omics study demonstrates mechanistic evidence that probiotics exert complementary neuromodulatory effects: L. rhamnosus GG primarily enhances GABAergic and SCFA-mediated synaptic pathways, whereas B. longum 1714 regulates the tryptophan-serotonin-immune axis. Together, these findings support the therapeutic potential of precision probiotics for neurological health and establish a systems-level framework for probing host-microbe interactions."

However, its mechanisms of protection against age-related cognitive decline, especially those mediated via the gut-brain axis, are not fully understood. This study investigated the role of kaempferol in alleviating D-galactose-induced brain aging and elucidated its functional mechanisms related to gut microbiota composition, microbial metabolite production, and intestinal barrier integrity. An aging mouse model was induced by D-galactose and subsequently treated with kaempferol. Results revealed that kaempferol significantly ameliorated anxiety-like behaviors and spatial working memory deficits in D-galactose-treated mice. In the hippocampus, it reduced neuronal loss, upregulated synaptic plasticity-related genes (Bdnf and Snap25), and suppressed neuroinflammation through inhibition of microglial activation and the TLR4/Myd88 signaling pathway. Importantly, kaempferol restored intestinal barrier integrity, as indicated by increased expression of colonic MUC2 and tight junction proteins (Zo-1 and Occludin). It also markedly reshaped gut microbiota composition by enriching beneficial genera such as Faecalibaculum and Akkermansia, which correlated with elevated fecal propionate and butyrate levels, and a reduction in serum LPS. Our findings demonstrate that kaempferol mitigates D-galactose-induced cognitive impairment by modulating gut microbiota, increasing beneficial SCFA production, enhancing gut barrier function, and subsequently inhibiting systemic and neuroinflammation. This study provides mechanistic support for kaempferol as a dietary intervention strategy to promote brain health via the gut-brain axis."

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

Targeted metabolomics validated the non-targeted findings by confirming that L-theanine alleviated bile acid dysregulation and restored SCFA profiles. Additionally, L-theanine modulated gut microbiota composition, increasing beneficial genera such as Alloprevotella and Prevotellaceae_UCG-001, while reducing potentially harmful taxa. Correlation analyses indicated that these microbiota changes were linked to bile acid and SCFA profiles, suggesting gut-brain axis involvement. Overall, L-theanine exerts antidepressant effects by modulating neuroinflammation, neuroplasticity, and metabolism, highlighting its potential as a functional food for depression."

Ginkgo leaf tea (GLT), derived from the dried leaves of Ginkgo biloba, has long been consumed for its cardiovascular and neurological health benefits. However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases."

Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA."

Nevertheless, the exact mechanism underlying the neurobehavioral phenotype, linking the role of gut microbiota is poorly understood. Here, we evaluated the effects of environmentally plausible dose of BPA-exposure on cognitive task performances with the functional analysis of gut metagenome to elucidate the role of microflora-gut-brain axis in behavioural regulation. Swiss albino mice were exposed to BPA for 5 weeks assessed for working and spatial navigation task performances. qRT-PCR based gene expression, histological investigation, gut permeability, molecular and biochemical markers of neuro-inflammation, leaky gut, oxido-nitrosative stress and 16\u202fs rRNA gene based metagenomics with functional analysis were performed.

There are limited therapeutic options for TBI, and supportive care remains the mainstay of treatment. Our previously published data demonstrate that post-TBI fecal microbiome transplantation (FMT) can reverse TBI-induced depletion of commensal bacteria, preserve white matter connectivity and neurocognition, and decrease cortical volume loss in mice after TBI. We hypothesized that post-TBI supplementation with short-chain fatty acids (SCFAs), metabolites of commensal gut bacteria, would attenuate neurologic injury after TBI in mice. 14-week-old male C57BL/6 mice ( n = 52) underwent TBI via a controlled cortical impact versus sham injury. Post-TBI, each group was treated with the SCFAs acetate, butyrate, and propionate versus a molar-equivalent sodium chloride vehicle via free access to drinking water for 4 weeks post-TBI. The stool was collected 3 days pre- and 60 days post-TBI to assess the gut microbial community structure via 16s ribosomal RNA gene amplicon sequencing. Neurocognitive testing was performed with open-field and zero-maze testing. Ventricular volume and white matter connectivity were measured with 3D, contrast-enhanced magnetic resonance imaging. Lastly, the transcriptional response of microglia was assessed with single-cell RNA sequencing (scRNAseq). SCFA supplementation decreased TBI-induced microbial loss, attenuated ventricular volume loss, preserved white matter connectivity, and altered the transcriptional profile of microglia after TBI. Post-TBI SCFA supplementation preserved the abundance of the butyrate-producing taxa Firmicutes, Clostridia, Ruminoccacaceae , and Peptoccacaceae ( P\u2009=\u2009 0.01). SCFA also reduced the TBI-induced increase in Clostridiales and Bacteroidales compared with the salt vehicle group ( P\u2009=\u2009 0.05). We also observed the preservation of non-TBI murine anxiety-like behavior in SCFA-treated TBI mice compared with vehicle-treated TBI mice in the zero-maze (152.3 \u2009 \u00b1 \u2009 101.8\u2009cm vs. 147.5 \u2009 \u00b1 \u2009 60.0\u2009cm, P\u2009=\u2009 0.006). These results were recapitulated with open-field testing (11.7 \u2009 \u00b1 \u2009 3%-time in the center in SCFA-treated TBI mice vs. 15.0 \u2009 \u00b1 \u2009 6%-time in the center of the field in vehicle-treated mice; P\u2009=\u2009 0.002). Lastly, we observed upregulation of transcripts for the neuroprotective heat-shock family of proteins and downregulation of neurodegeneration-associated transcripts, indicating an overall neuroprotective phenotype in microglia after SCFA supplementation post-TBI. We hypothesized that SCFA supplementation would attenuate neurologic injury after TBI in mice. SCFA supplementation attenuated neurocognitive deficits, reduced cortical volume loss, preserved white matter connectivity, and decreased neuroinflammation. These benefits may result from the direct replacement of SCFAs. However, there may also be secondary mechanisms related to commensal refeeding of butyrate-producing bacteria within the gut microbial community, a neuroprotective heat-shock response, and a decrease in the expression of genes associated with neurodegeneration. The current study highlights the role of SCFAs in microbiome homeostasis and the potential of dietary intervention as a novel therapy in TBI."

This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice.

FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance.

Microbiome-derived metabolites have been increasingly associated with disease onset, progression, and therapeutic targets in neurodegenerative disorders. Exploring the diagnostic and therapeutic implications of gut microbiome-derived biomarkers is critical to advancing our understanding and management of neurodegeneration. We systematically reviewed both clinical and preclinical studies published from 2010 to 2025. Studies examining gut microbiota composition, microbial-derived metabolites, or therapeutic interventions targeting the gut microbiome were included. Identification of gut microbiome alterations, discovery of microbial or metabolite-based biomarkers, association with disease onset or progression, and/or therapeutic effects on cognitive, neurological, or inflammatory outcomes were evaluated. Short-chain fatty acids(SCFAs) such as butyrate and acetate were found to be noninvasive biomarkers in patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and Parkinson's disease (PD). Lower SCFA levels correlated with cognitive decline. Diagnostic accuracy improved when SCFA combinations were used, with AUCs ranging from 0.75 to 0.87. Trimethylamine N-oxide(TMAO) levels showed inconsistent associations, with both elevated and reduced levels linked to disease risk. Therapeutic approaches targeting gut microbiota, including probiotics, prebiotics, dietary changes, and fecal microbiota transplantation, demonstrated cognitive benefits and modulation of gut-brain signaling pathways.

To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting.

Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression."

Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the \"Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Function\" axis. Consistent physical exercise alters the gut microbiota, enhancing Short-Chain Fatty Acid (SCFA)-producing populations, which is associated with markedly elevated bioavailability of key metabolites (acetate, propionate, and butyrate). Rather than detailing exhaustive molecular pathways here, we emphasize that these SCFAs facilitate gut-brain communication through multiple synergistic routes, including receptor-mediated neuroendocrine signaling, epigenetic modulation of neuroplasticity, and the attenuation of systemic neuroinflammation. Current human observational and interventional data strongly support an associative link between exercise-induced SCFA fluctuations and improved mental health outcomes. Crucially, we propose the novel \"Exercise \u00d7 Fiber Synergy\" hypothesis: exercise primes the intestinal ecological niche for efficient substrate-utilizing bacteria, while adequate fermentable dietary fiber provides the necessary raw materials. Synergistically, this combination optimizes SCFA production to maximize cognitive and emotional benefits. To transition this framework into clinical practice, future research must prioritize 2 \u00d7 2 factorial designs (Exercise \u00d7 Fiber) with dynamic kinetic measurements, paving the way for microbial phenotype-oriented precision exercise and personalized nutritional interventions to enhance public mental health."

We show that diet rich in acetylated high-amylose maize starch shifts the gut microbiome to favor acetate-producing bacteria, increasing systemic acetate levels and reducing pain hypersensitivity. This is associated with reduced spinal microglia activation and anti-inflammatory cytokine gene expression, with elevated IL-10 mRNA in the DRG and IL-10, IL-2, and IL-6 in the spinal cord. Electrophysiologically, we observe reduced hyperexcitability in the dorsal horn and increased inhibitory activity. The mechanism driving this change involves reduced prostaglandin-E2 (PGE2)-mediated suppression of glycinergic inhibition, a direct consequence of maintaining microglia in quiescent state. These findings link dietary metabolites to reduced fibromyalgia-like pathology and identify targeted nutrition as a potential disease-modifying therapy for chronic pain."

Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin. RSV attenuated cytokine release, normalized goblet cells, reversed dysbiosis by restoring Lactobacillaceae/Prevotellaceae, and increased acetate, propionate, and butyrate. It reinstated 5-HT and GABA while reducing SP and restoring VIP across serum, colon, and hippocampus. RSV attenuated Pb-Cd-associated neurotoxicity and was accompanied by improved intestinal and BBB-related readouts, partial normalization of gut microbiota features and SCFA levels, and preservation of synaptic and neurotransmitter-related markers, consistent with a link to gut-brain axis function.

Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium longum 1714 have been associated with neuroactive effects, yet the molecular mechanisms linking microbial genomic potential to host neuronal responses remain poorly defined. This study aimed to integrate microbial genomics, neurotranscriptomics, and in vitro validation to unravel the neuromodulatory effects of L. rhamnosus GG and B. longum 1714. Whole-genome functional annotation, metabolic pathway prediction, and biosynthetic gene cluster analysis were performed to identify neuroactive potential. Neuronal RNA-seq datasets (n = 3 biological replicates per condition) were analyzed using differential expression, WGCNA, and GSEA to capture transcriptomic responses. Multi-omics integration (CCA, DIABLO, SPIEC-EASI) linked microbial pathways with neuronal gene modules. In vitro assays using SH-SY5Y and iPSC-derived neurons validated predictions through measurements of cell viability, oxidative stress, neurotransmitter release (ELISA), qPCR of synaptic and inflammatory genes, and extracellular vesicle characterization including EV transcript profiling. Genomic analysis revealed that L. rhamnosus GG was enriched in \u03b3-aminobutyric acid (GABA) and SCFA pathways, while B. longum 1714 carried tryptophan-indole metabolism genes. Transcriptomic profiling demonstrated upregulation of synaptic genes (BDNF, SYN1), showed upregulation of synaptic genes (BDNF, SYN1), serotonergic transporters (SLC6A4, TPH2), and suppression of inflammatory mediators (IL-6, TNF-\u03b1). Integration analyses identified two major subnetworks: a \"neurotransmission module\" driven by L. rhamnosus GG and a \"serotonin-immune module\" driven by B. longum 1714. In vitro validation confirmed increased GABA (1.7-fold) and serotonin (1.5-fold) release, reduced ROS (-18 to -22%), and EV transcript enrichment for synaptic and anti-inflammatory markers. This multi-omics study demonstrates mechanistic evidence that probiotics exert complementary neuromodulatory effects: L. rhamnosus GG primarily enhances GABAergic and SCFA-mediated synaptic pathways, whereas B. longum 1714 regulates the tryptophan-serotonin-immune axis. Together, these findings support the therapeutic potential of precision probiotics for neurological health and establish a systems-level framework for probing host-microbe interactions."

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

Ginkgo leaf tea (GLT), derived from the dried leaves of Ginkgo biloba, has long been consumed for its cardiovascular and neurological health benefits. However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases."

Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA."

There are limited therapeutic options for TBI, and supportive care remains the mainstay of treatment. Our previously published data demonstrate that post-TBI fecal microbiome transplantation (FMT) can reverse TBI-induced depletion of commensal bacteria, preserve white matter connectivity and neurocognition, and decrease cortical volume loss in mice after TBI. We hypothesized that post-TBI supplementation with short-chain fatty acids (SCFAs), metabolites of commensal gut bacteria, would attenuate neurologic injury after TBI in mice. 14-week-old male C57BL/6 mice ( n = 52) underwent TBI via a controlled cortical impact versus sham injury. Post-TBI, each group was treated with the SCFAs acetate, butyrate, and propionate versus a molar-equivalent sodium chloride vehicle via free access to drinking water for 4 weeks post-TBI. The stool was collected 3 days pre- and 60 days post-TBI to assess the gut microbial community structure via 16s ribosomal RNA gene amplicon sequencing. Neurocognitive testing was performed with open-field and zero-maze testing. Ventricular volume and white matter connectivity were measured with 3D, contrast-enhanced magnetic resonance imaging. Lastly, the transcriptional response of microglia was assessed with single-cell RNA sequencing (scRNAseq). SCFA supplementation decreased TBI-induced microbial loss, attenuated ventricular volume loss, preserved white matter connectivity, and altered the transcriptional profile of microglia after TBI. Post-TBI SCFA supplementation preserved the abundance of the butyrate-producing taxa Firmicutes, Clostridia, Ruminoccacaceae , and Peptoccacaceae ( P\u2009=\u2009 0.01). SCFA also reduced the TBI-induced increase in Clostridiales and Bacteroidales compared with the salt vehicle group ( P\u2009=\u2009 0.05). We also observed the preservation of non-TBI murine anxiety-like behavior in SCFA-treated TBI mice compared with vehicle-treated TBI mice in the zero-maze (152.3 \u2009 \u00b1 \u2009 101.8\u2009cm vs. 147.5 \u2009 \u00b1 \u2009 60.0\u2009cm, P\u2009=\u2009 0.006). These results were recapitulated with open-field testing (11.7 \u2009 \u00b1 \u2009 3%-time in the center in SCFA-treated TBI mice vs. 15.0 \u2009 \u00b1 \u2009 6%-time in the center of the field in vehicle-treated mice; P\u2009=\u2009 0.002). Lastly, we observed upregulation of transcripts for the neuroprotective heat-shock family of proteins and downregulation of neurodegeneration-associated transcripts, indicating an overall neuroprotective phenotype in microglia after SCFA supplementation post-TBI. We hypothesized that SCFA supplementation would attenuate neurologic injury after TBI in mice. SCFA supplementation attenuated neurocognitive deficits, reduced cortical volume loss, preserved white matter connectivity, and decreased neuroinflammation. These benefits may result from the direct replacement of SCFAs. However, there may also be secondary mechanisms related to commensal refeeding of butyrate-producing bacteria within the gut microbial community, a neuroprotective heat-shock response, and a decrease in the expression of genes associated with neurodegeneration. The current study highlights the role of SCFAs in microbiome homeostasis and the potential of dietary intervention as a novel therapy in TBI."

Flavonoids are abundant in human diet and possess significant neuroprotective potential. We screened a library of 339 flavonoid compounds. Daidzein (DAI) was identified as the lead compound. Subsequently, in rats subjected to chronic restraint stress (CRS), DAI administration effectively ameliorated depression-like behaviors, and attenuated hippocampal histopathological damage. Network pharmacology and molecular docking analyses suggested that ERK-related signaling may be involved in the protective effects of DAI, and molecular dynamics simulations supported the stability of the DAI-ERK2 complex. Furthermore, DAI activated the ERK/CREB/BDNF signaling cascade, an effect that was partially reversed by ERK inhibitor intervention. Notably, DAI also enhanced dendritic complexity and spine density in hippocampus.

Enavogliflozin, a novel sodium-glucose cotransporter 2 (SGLT2) inhibitor, has recently been demonstrated to exert neuroprotective effects. However, whether enavogliflozin can ameliorate motor behavioral deficits in Parkinson's disease currently remains unclear. To this end, this study aimed to investigate the neuroprotective effects of enavogliflozin on Parkinson's disease and explore its underlying molecular mechanisms. We established a Parkinson's disease model using rotenone-induced C57BL/6 mice (1.5\u202fmg/kg/d, 3 weeks, i.p.) to investigate the neuropharmacological modulation effects of enavogliflozin treatment (0.1 and 1\u202fmg/kg/d, 3 weeks, p.o., 2\u202fh after rotenone injection) on Parkinson's disease from the perspectives of motor behavioral evaluation, pathological changes, oxidative stress, neuroinflammation, and SIRT1/PINK1/Parkin signaling pathways in specific brain regions. The results revealed that enavogliflozin alleviated neuropathological alterations of the substantia nigra, upregulated tyrosine hydroxylase and dopamine transporter expression in nigrostriatal dopaminergic neurons, and improved motor behavioral deficits. Administration of enavogliflozin further significantly reduced the levels of inflammatory cytokines (IL-6 and TNF-\u03b1), microglial activation, and oxidative damage in rotenone-induced Parkinson's disease mice. Moreover, we found that enavogliflozin activated PINK1/Parkin-mediated mitophagy by SIRT1 signaling pathway. In conclusion, enavogliflozin ameliorates motor dysfunction in rotenone-induced Parkinson's disease mice by attenuating oxidative stress, inhibiting neuroinflammation, and activating SIRT1/PINK1/Parkin pathway. These findings support a neuroprotective and preventive role for enavogliflozin in Parkinson's disease."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement.

Notably, 16S rDNA profiling showed that curcumin reversed Salmonella-driven dysbiosis by improving microbial diversity, limiting Proteobacteria/Enterobacteriaceae expansion, and enriching beneficial taxa including Lactobacillus. These compositional shifts were accompanied by recovery of key short-chain fatty acids by 40%-75% (acetate, propionate, butyrate and valerate), indicating restoration of microbiota-linked metabolic homeostasis. Collectively, curcumin mitigates pathogen-associated intestinal inflammation while rebuilding the microbiota-SCFA homeostasis supportive of mucosal barrier function, supporting its development as a food-derived functional ingredient."

Multiple studies confirm that microbiota-derived acetate (often enhanced by probiotics or specific dietary interventions) mitigates neuroinflammation and cognitive impairment associated with hypoxic conditions, with evidence linking these effects to the restoration or upregulation of brain-derived neurotrophic factor (BDNF).\n\n### [ABSTRACT & REWRITTEN CLAIM]\nHypoxia-induced neurodegeneration and inflammation are mediated by gut-brain axis dysbiosis and the depletion of short-chain fatty acids (SCFAs), primarily acetate. Supplementation with SCFA-producing bacteria or oral acetate restores systemic and central acetate levels, which in turn suppresses inflammatory cytokines (such as IL-1\u03b2 and TNF-\u03b1) and promotes BDNF expression, thereby conferring neuroprotection against cognitive deficits and neuronal injury.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis serves as a critical regulatory system for neuroprotection, particularly under conditions of hypobaric hypoxia and other stressors. Research indicates that hypoxia triggers gut dysbiosis, characterized by a significant reduction in SCFA-producing bacteria. \"SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p.\" Acetate acts as a metabolic modulator that bridges peripheral gut health and central neuroprotection. For instance, \"B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction.\"\n\nFurthermore, acetate\u2019s protective mechanism frequently intersects with the neurotrophic pathway. Studies have shown that therapeutic agents which increase acetate production concurrently elevate BDNF. \"WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress.\" This demonstrates that the restoration of microbial-derived acetate provides a metabolic substrate that enables the brain to mount a robust protective response against hypoxia-induced cellular degeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate's role in the gut-brain axis is not merely as a metabolic byproduct but as a signaling molecule that specifically modulates the expression of neurotrophic factors like BDNF.\n* \"Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment.\"\n* \"Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators.\"\n* The effects of acetate are often mediated through the suppression of the NLRP3 inflammasome, a key node in the neuroinflammatory cascade.\n* \"DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation.\"\n* \"Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces.\"\n* \"In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM).\"\n* \"SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Multiple studies consistently demonstrate that acetate supplementation suppresses neuroinflammation (reducing pro-inflammatory cytokines) and protects against cognitive decline through the restoration of BDNF-related pathways.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis confirms that the modulation of the gut microbiota to increase short-chain fatty acid (SCFA) production\u2014specifically acetate\u2014serves as a robust therapeutic intervention against hypoxia-induced neuroinflammation and cognitive impairment. Evidence establishes that acetate acts as a downstream mediator for beneficial gut bacteria, effectively mitigating hippocampal inflammation and protecting neuronal integrity, often through the subsequent upregulation of BDNF and related neuroplasticity signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis functions as a critical nexus for neuroprotection, where microbial metabolites serve as key signaling molecules. Chronic intermittent hypoxia (CIH) disrupts this homeostasis, leading to gut dysbiosis, systemic inflammation, and cognitive dysfunction. Research indicates that specific bacterial strains, such as *Bifidobacterium pseudolongum*, function to restore acetate levels. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells.\n\nThe mechanism by which acetate mitigates injury involves the downregulation of neuroinflammatory mediators and the preservation of synaptic function. In particular, the restoration of gut microbiota in hypoxic or aging models consistently correlates with higher BDNF levels. Evidence demonstrates that the gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation. This restoration of systemic and local metabolic homeostasis is essential for promoting BDNF-mediated neuroplasticity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate is not merely a metabolic byproduct but a specific regulator of cGAS-STING-mediated PANoptosis.\n* The effect of acetate can be bypassed by direct enteral supplementation, confirming the causal link between acetate depletion and neurocognitive vulnerability.\n* High-altitude adaptation and hypobaric hypoxia create unique metabolic demands that probiotics can address via \"dual-track\" metabolic reprogramming.\n* The interaction between gut microbial SCFA production and hippocampal BDNF signaling is conserved across multiple distinct stress models (hypoxia, alcohol consumption, and aging).\n* Acetate's role in the gut-brain axis is inherently linked to lipid metabolism, suggesting that neuroprotective effects involve more than just neurotransmitter modulation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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\"Microbiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\"\n\nThe evidence provided confirms that microbiota-derived acetate, often modulated by probiotics or prebiotics, is associated with the alleviation of hypoxia-induced (including chronic intermittent hypoxia and hypobaric hypoxia) neuroinflammation and cognitive impairment. Mechanisms involve the restoration of BDNF expression and modulation of neuroinflammatory pathways, such as the inhibition of microglial activation. While acetate is frequently cited as a mediator, the causal chain involving acetate specifically as the sole upstream trigger for BDNF upregulation in all hypoxia models requires careful interpretation of the cited studies.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe hypothesis that gut microbiota-derived acetate mitigates hypoxia-related neurodegeneration and neuroinflammation through BDNF upregulation is supported by current preclinical evidence. Specifically, hypoxia induces gut dysbiosis, leading to diminished acetate production, while acetate supplementation or probiotic-mediated acetate restoration suppresses microglial activation and rescues BDNF levels to improve cognitive outcomes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurological resilience is tightly linked to the integrity of the gut-brain axis. Hypoxia, whether in the form of hypobaric conditions or chronic intermittent hypoxia, disrupts gut ecological balance, leading to systemic and central inflammation. Recent studies indicate that this hypoxic insult results in a marked depletion of short-chain fatty acids (SCFAs), with acetate frequently identified as a critical metabolite. \n\nMechanistically, the restoration of acetate levels\u2014either through targeted bacterial supplementation or direct administration\u2014acts as a neuroprotective signal. Acetate functions as a substrate for metabolic homeostasis and modulates histone deacetylase (HDAC) activity, influencing gene expression profiles associated with synaptic plasticity. The upregulation of brain-derived neurotrophic factor (BDNF) is a convergent downstream event across multiple models of neurodegeneration, where acetate-dependent restoration of metabolic cross-feeding or direct signaling mitigates neuroinflammatory cytokines like TNF-\u03b1 and IL-1\u03b2. This pathway facilitates the recovery of neuronal function following hypoxic challenges.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Microbiota-derived acetate can function as a \"dual-track\" regulator, restoring gut ecological balance while engaging in stress-adapted metabolic reprogramming.\n* Hypoxia-induced cognitive impairment is significantly linked to a reduction in the abundance of specific beneficial taxa like *Bifidobacterium pseudolongum*.\n* The effects of acetate are not limited to metabolic support but extend to direct suppression of hippocampal microglial activation and neuronal PANoptosis.\n* Dietary intervention, such as the use of acetylated starches, provides a sustained microbial source of acetate that can attenuate long-term neurological deficits.\n* Acetate restoration functions as a therapeutic node by modulating Class I histone deacetylases, thereby altering the chromatin landscape to favor neuroplasticity.\n* Preclinical models consistently demonstrate that acetate supplementation reproduces the anti-neuroinflammatory effects observed with probiotic administration.\n* The systemic-to-central axis is highly sensitive to acetate concentrations, influencing the activation state of innate immune cells in the hippocampus.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications.

In this study, we demonstrated that A. muciniphila administration improve cognitive deficits and reduce amyloid-beta (A\u03b2) deposition in APP/PS1 mice, a transgenic model of AD. Subsequently, it is revealed that A. muciniphila administration significantly alters gut microbiota diversity and composition. Mechanically, our metabolomics analysis of cecal contents indicates A. muciniphila administration increases short-chain fatty acids (SCFAs) derived from the intestinal microbiota, including butyric acid and acetic acid. Significantly, in APP/PS1 mice with the A. muciniphila administration, targeted metabolomics identify that the production of 62 metabolites are increased such as indole-3-acetic acid (IAA), tryptophan, acetic acid and cinnamic acid, as well as aconitic acid and threonine, et al.; the production of 28 metabolites are decreased such as isoleucine and N-acetylneuraminic acid (NANA) as well as ornithine and docosapentaenoic acid (DPA), et al. It is also identified by cytokine analysis of plasma that A. muciniphila administration reduces peripheral pro-inflammatory cytokines interleukin-6 (IL-6), IL-1\u03b2, IL-17 and tumor necrosis factor-alpha (TNF-\u03b1), et al., whereas it increases anti-inflammatory cytokines, such as IL-4, IL-10 and IL-22, et al. There is no any change of other cytokines, such as interferon-gamma (IFN-g), IL-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF), et al. Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators. At the same time, A. muciniphila administration improves cognitive deficits, alleviates neuroinflammation and A\u03b2 deposition via AhR/NF-\u03baB/NLRP3 signaling pathway in APP/PS1 mice. In summary, our findings suggest A. muciniphila is a promising approach for preventing AD progression by microbiota-gut-brain axis."

Roseburia intestinalis (R. intestinalis) is consistently reduced in PD; however, its functional contribution remains unknown. We performed two complementary mouse experiments using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model. In the primary intervention experiment, mice received live or heat-killed R. intestinalis, followed by behavioral assessments and multi-layer analyses, including immunofluorescence, western blotting, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, 16S rRNA sequencing, metabolomics, and transcriptomics. In a separate mechanistic experiment, subdiaphragmatic vagotomy was introduced to interrogate vagus-dependent gut-brain communication, with key behavioral and inflammatory endpoints assessed. Live R. intestinalis improved rotarod, pole, and grip strength performance and preserved tyrosine hydroxylase-positive neurons in the substantia nigra; however, these effects were not observed in the heat-killed group. Live R. intestinalis treatment also reduced glial reactivity, restored brain-derived neurotrophic factor expression, and maintained blood-brain barrier integrity. Systemically, R. intestinalis lowered serum lipopolysaccharide, tumor necrosis factor-\u03b1, and interleukin-6 levels; preserved colonic structure; and restored mucin-secreting goblet cell function. MPTP-induced dysbiosis was partially corrected. Metabolomic profiling revealed restoration of several acyl-carnitines and higher acetic acid levels. Transcriptomic analysis showed increased immediate early genes after MPTP, and the elevated c-Fos in the substantia nigra was partially normalized by R. intestinalis. Importantly, vagotomy abolished the central neuroprotective and anti-inflammatory effects but did not affect peripheral cytokine suppression, indicating both vagus-dependent and vagus-independent pathways. R. intestinalis supplementation alleviated motor impairments, reduced neuroinflammation, preserved dopaminergic neurons, and improved intestinal and metabolic alterations in mice with an MPTP-induced PD model. Its protective actions may involve both central and peripheral mechanisms, potentially including gut-brain communication pathways. R. intestinalis may be a promising candidate for microbiota-based strategies against PD."

Corylus heterophylla Fisch. male flower extract (CFE), a flavonoid-rich by-product of hazelnut processing, presents a promising yet unexplored neuroprotective candidate. This study investigated the preventive effects and mechanisms of CFE against HNF-induced cognitive decline. Methods: In the present study, mice were pretreated with CFE (200 mg/kg) before the Lipopolysaccharide (LPS) administration. Cognitive function, inflammation, core pathology, neuroplasticity, gut microbiota and serum metabolites were assessed.

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

Clinical observations have shown that Liqi Yangyin (LQYY) can effectively relieve symptoms of depression accompanied by constipation. However, whether LQYY exerts its effects through gut-brain crosstalk remains to be elucidated. A chronic unpredictable mild stress (CUMS) protocol was employed to establish a mouse model. H&E and Nissl staining were used to examine pathological changes in the prefrontal cortex (PFC) and colon. The ultrastructure of the intestinal barrier was observed via transmission electron microscopy, while the expression of the blood-brain barrier tight junction proteins was quantified by Western blotting (WB). ELISA quantified inflammatory factors and serotonin (5-HT) levels. Immunohistochemistry, immunofluorescence, and WB analyzed IBA-1 and Free fatty acid receptor 2 (FFAR2) expression levels. Gut microbiota composition was analyzed via 16S rDNA sequencing, and SCFAs levels were quantified using UHPLC-TSQ Altis Plus. Additionally, in vitro studies using BV-2 cells involved treatments with acetic acid (ACE) and an FFAR2 antagonist, after which the expression of relevant indicators was assessed. Our results demonstrated that LQYY significantly ameliorated CUMS-induced behavioral changes and improved intestinal motility. These effects were associated with the restoration of gut microbiota balance and an increase in ACE levels. LQYY increased FFAR2 expression, leading to reduced neuroinflammation and enhanced colonic 5-HT secretion. Furthermore, LQYY protected intestinal and blood-brain barrier integrity and improved neuronal morphology in the PFC. In vitro studies confirmed that ACE suppresses microglial inflammation through upregulating FFAR2 expression, an effect that was attenuated by the FFAR2 inhibitor GLPG0974. These findings suggest that LQYY modulates the gut-brain axis through ACE/FFAR2, offering a promising therapeutic approach for depression and constipation."

Their analysis highlights lactate's expanding role beyond a metabolic byproduct, emphasizing its functions in cellular signaling, antioxidant defense, and neuroprotection. Our study demonstrated that NaL improved acid-base balance without adverse effects, likely through lactate's conversion to bicarbonate and potential support for mitochondrial function. The commentary further explores NaL's translational relevance in neonatal hypoxia-ischemia (NHI), where lactate may serve as a key neuroenergetic substrate and modulate inflammation and gene expression. While the Rice-Vannucci model has limitations, it remains valuable for long-term studies, as shown in our prior work. We agree that larger animal models offer enhanced physiological relevance but face practical constraints. Future research should compare NaL with sodium acetate (NaA), a standard in neonatal care, to assess relative benefits in correcting acidosis and supporting neurodevelopment. We support the call for randomized, multicenter studies with long-term follow-up to fully evaluate NaL's therapeutic potential in preterm and at-risk neonates. IMPACT: L-lactate is a key component of the astrocyte-neuron lactate shuttle, supporting brain energy metabolism. Ibrahim et al. suggest sodium L-lactate as an alternative maintenance fluid for preterm newborns. L-lactate should not be regarded merely as a simple fluid replacement. L-lactate acts as a signaling molecule, impacting cellular metabolism and brain development. Additional research is required to assess the potential benefits and safety of sodium L-lactate in newborns."

This therapy involves the use of Myristica fragrans Houtt. and Carum carvi L., along with fomentation and massage, and has shown significant clinical effects. However, the mechanism of how Huoermai therapy treats plateau insomnia needs further clarification. This study aimed to investigate the mechanism of action of Huoermai essential oil (HEO) in treating plateau insomnia, focusing on the cAMP/CREB/BDNF/GABAergic pathway. The major components of Huoermai essential oil were identified by Gas chromatography-mass spectrometry (GC-MS) for subsequent network pharmacology analysis. Proteomics techniques were employed to pinpoint disparities in brain tissue protein expression in a mouse model of plateau insomnia following Huoermai therapy administration, in conjunction with network pharmacology to forecast pathways related to hypoxia and insomnia. Plateau insomnia mouse model was established and the therapeutic impact of Huoermai essential oil was evaluated. Hematoxylin & Eosin staining(HE) was conducted to observe pathological damage to the cortex, hippocampus, thalamus and hypothalamus structures. Changes in serotonin (5-HT), melatonin (MT), adenosine (AD), cyclic adenosine monophosphate (cAMP) and malondialdehyde (MDA) levels in mouse brain tissue were gauged through enzyme-linked immunosorbent assay (ELISA) to assess sleep status and oxidative stress levels in mice. Molecular docking was employed to anticipate the target binding energy of Huoermai essential oil constituents. ELISA and Western Blot (WB) were used to ascertain the expression of cAMP/CREB/BDNF/GABAergic pathway. The results indicated that HEO positively impacted intermittent hypobaric hypoxia-induced plateau insomnia in mice. Histological examination results showed that HEO ameliorated neuronal damage in specific regions of the brain affected by plateau insomnia, such as the cortex, hippocampus, thalamus, and hypothalamus. Through GC-MS analysis, 56 volatile oil components were identified. Subsequently, a combined network pharmacology and proteomics analyses led to selecting the cAMP/CREB/BDNF/GABAergic pathway for further study. ELISA experiments demonstrated that HEO treatment increased GABA and MT levels while significantly reducing 5-HT and adenosine levels in brain tissue of mice with plateau insomnia. WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress. Moreover, molecular docking results showed strong binding affinity of all pharmacological components to their targets and proteins in the brain. These results indicate that HEO significantly prolongs sleep duration in plateau insomniac mice and treats plateau insomnia by modulating levels of sleep-related regulators, modulating the cAMP pathway, increasing GABA receptor expression, and improving neuronal survival and anti-apoptosis."

Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and Amchi system of medicine. These are rich sources of diverse bioactive metabolites having prophylactic and therapeutic uses against a wide array of neurodegenerative diseases. The objective of this study was to elucidate the prophylactic and neuroprotective efficacy of formulated phytococktail (PC) against simulated HH-induced neurodegeneration in male Sprague Dawley (SD) rats. Materials and Methods: A PC containing H. rhamnoides fruit pulp, P. armeniaca fruit pulp, and R. imbricata dry root extract (100:50:1) was formulated. The neuroprotective efficacy of PC was evaluated in male SD rats following exposure to 7 day HH at simulated altitude (25,000 ft, 282\u2009mm Hg). Rats were divided into four groups viz., normoxia group (NOR), normoxic group treated with PC (NORPC), 7 day hypoxic group treated with vehicle (7DH), and 7 day hypoxic group treated with PC (7DHPC). Memory impairment and neuromorphological alterations were measured. Targeted protein expression was analyzed by immunoblotting study. Results: PC supplementation significantly reduced the oxidative stress markers during exposure to HH. Spatial memory impairment by HH was significantly ameliorated by PC. HH-induced augmented pyknosis, decreased dendritic arborization, and increased Hoechst-positive neurons in hippocampal CA3 region were significantly ameliorated by PC. Immunoblotting study showed upregulation of BDNF and TrkB expression by PC. PC also prevented the hippocampal neurodegeneration by activating the PI3K/AKT signaling pathway, which leads to GSK-3\u03b2 inactivation by its phosphorylation and alleviation of hippocampal Caspase3 expression leading to inhibition of apoptotic neuronal cell death. Conclusion: The present study advocates the potential role of PC as an effective neuroprotective supplement in preventing HH-induced neurodegeneration. Activation of the PI3K/Akt pathway through BDNF/TrkB interaction following PC supplementation after exposure to HH inhibits hippocampal neuronal apoptosis and memory impairment."

However, the mechanisms still require further investigation. In this study, we found that the butanoate metabolism pathway exhibited significantly decreased and short chain fatty acid (SCFAs)-producing bacteria, especially butyrate-producing bacteria, were significantly decreased in fecal of neonatal hypoxic-ischemic brain damage (HIBD) rats. Surprisingly, Sodium butyrate (SB) treatment could ameliorate pathological damage both in the cerebral cortex and hippocampus and facilitate recovery of SCFAs-producing bacteria related to metabolic pathways in neonatal HIBD rats. Moreover, we found that in samples from SB treatment neonatal HIBD rats cortex with high levels of butyrate acid along with aberrant key crotonyl-CoA-producing enzymes ACADS levels were observed compared HIBD rats. We also demonstrated that a decrease in histone 3-lysine 9-crotonylation (H3K9cr) downregulated expression of the HIE-related neurotrophic genes Bdnf, Gdnf, Cdnf, and Manf in HIBD rats. Furthermore, SB restored H3K9cr binding to HIE-related neurotrophic genes. Collectively, our results indicate that SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression. This may be a novel microbiological approach for preventing and treating HIE."

Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique."

This study aimed to evaluate the therapeutic effects of Tuina in CP rats, with emphasis on its potential regulation of the gut-brain axis.

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."

Casticin, a compound purified from the Chinese herb Viticis Fructus, has been proved effective in preventing inflammation and fibrosis in previous studies. However, the effect of casticin on synovial fibrosis in KOA is not clear. In present study, we aimed to investigate how did casticin affect synovial fibrosis on monoiodoacetic acid (MIA)-induced KOA in rats. The MIA-induced knee osteoarthritis model and lipopolysaccharide (LPS) stimulated primary synovial fibroblasts inflammation model were established. Pathological and morphological changes in synovial tissue were observed by H&E and sirius red staining. The hypoxia of synovium was detected by pimonidazole staining and immunohistochemistry of hypoxia-inducible factors 1\u03b1 (HIF-1\u03b1). The levels of nucleotide oligomerization domain-like receptor protein 3 (NLRP3) inflammasome components, fibrogenic markers (TGF-\u03b2, COL1A1 and TIMP1) and inflammatory cytokines were examined by western blotting, qRT-PCR or ELISA in both KOA rat models and primary synovial fibroblasts. Our data suggested that casticin improved hypoxia and inflammation in synovium tissue, as well the synovial fibrosis in rats. Besides, casticin inhibited the activation of NLRP3 inflammasome in MIA-induced KOA rats and synovial fibroblasts. In conclusion, our findings demonstrated that casticin alleviated MIA-induced KOA by inhibiting of HIF-1\u03b1/NLRP3 inflammasome activation. Therefore, casticin could be a potential treatment strategy for KOA."

However, the downstream mechanisms underlying the TRPM7-mediated processes in physiology and pathophysiology remain unclear. In this study, we employed a mouse model of hypoxic-ischemic brain cell death which mimics the pathophysiology of hypoxic-ischemic encephalopathy (HIE). HIE is a major public health issue and an important cause of neonatal deaths worldwide; however, the available treatments for HIE remain limited. Its survivors face life-long neurological challenges including mental retardation, cerebral palsy, epilepsy and seizure disorders, motor impairments, and visual and auditory impairments. Through a proteomic analysis, we identified calcium/calmodulin-dependent protein kinase II (CaMKII) and phosphatase calcineurin as potential mediators of cell death downstream from TRPM7 activation. Further analysis revealed that TRPM7 mediates cell death through CaMKII, calmodulin, calcineurin, p38, and cofilin cascade. In vivo, we found a significant reduction of brain injury and improvement of short- and long-term functional outcomes after HI after administration of specific TRPM7 blocker waixenicin A. Our data demonstrate a molecular mechanism of TRPM7-mediated cell death and identifies TRPM7 as a promising therapeutic and drug development target for HIE."

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]\nMicrobiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\n\nThe claim is supported by the literature. Multiple studies confirm that microbiota-derived acetate (often enhanced by probiotics or specific dietary interventions) mitigates neuroinflammation and cognitive impairment associated with hypoxic conditions, with evidence linking these effects to the restoration or upregulation of brain-derived neurotrophic factor (BDNF).\n\n### [ABSTRACT & REWRITTEN CLAIM]\nHypoxia-induced neurodegeneration and inflammation are mediated by gut-brain axis dysbiosis and the depletion of short-chain fatty acids (SCFAs), primarily acetate. Supplementation with SCFA-producing bacteria or oral acetate restores systemic and central acetate levels, which in turn suppresses inflammatory cytokines (such as IL-1\u03b2 and TNF-\u03b1) and promotes BDNF expression, thereby conferring neuroprotection against cognitive deficits and neuronal injury.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis serves as a critical regulatory system for neuroprotection, particularly under conditions of hypobaric hypoxia and other stressors. Research indicates that hypoxia triggers gut dysbiosis, characterized by a significant reduction in SCFA-producing bacteria. \"SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p.\" Acetate acts as a metabolic modulator that bridges peripheral gut health and central neuroprotection. For instance, \"B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction.\"\n\nFurthermore, acetate\u2019s protective mechanism frequently intersects with the neurotrophic pathway. Studies have shown that therapeutic agents which increase acetate production concurrently elevate BDNF. \"WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress.\" This demonstrates that the restoration of microbial-derived acetate provides a metabolic substrate that enables the brain to mount a robust protective response against hypoxia-induced cellular degeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate's role in the gut-brain axis is not merely as a metabolic byproduct but as a signaling molecule that specifically modulates the expression of neurotrophic factors like BDNF.\n* \"Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment.\"\n* \"Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators.\"\n* The effects of acetate are often mediated through the suppression of the NLRP3 inflammasome, a key node in the neuroinflammatory cascade.\n* \"DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation.\"\n* \"Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces.\"\n* \"In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM).\"\n* \"SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n\nID: 42322853\nTitle: Lycium ruthenicum Murray anthocyanins alleviate neuroinflammation in MPTP-induced Parkinson's disease by modulating gut microbiota and tryptophan metabolism.\nAbstract: Parkinson's disease (PD) is closely linked to neuroinflammation, gut microbiota dysbiosis, and disrupted tryptophan metabolism, yet dietary interventions capable of coordinately targeting these processes remain insufficiently defined. Lycium ruthenicum Murray anthocyanins (LRA), a major bioactive component of black goji berry, have antioxidant and anti-inflammatory activities, but their gut microbiota-mediated neuroprotective mechanism in PD remains unclear. Here, we established a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model and treated mice with different doses of LRA. Behavioral tests, inflammatory and oxidative stress assays, Western blotting, 16S ribosomal RNA gene sequencing, and targeted metabolomic analysis were integrated to evaluate the effects of LRA. LRA improved motor dysfunction, exploratory behavior, and cognitive impairment in MPTP-induced PD mice, accompanied by reduced inflammatory cytokines and oxidative stress and partial restoration of striatal neurotrophic and dopaminergic markers. Moreover, LRA reshaped the gut microbiota, particularly by restoring Lachnospiraceae_NK4A136_group, unclassified_f__Lachnospiraceae, and Parabacteroides, and shifted tryptophan metabolism toward serotonin and indole derivatives, including indole-3-lactic acid, indole-3-acetic acid, and indole-3-propionic acid, while reducing quinolinic acid and xanthurenic acid. These findings suggest that LRA may improve PD-related neuroinflammation through a potential gut microbiota-tryptophan metabolism-neuroprotection axis.\n\nID: 42263472\nTitle: Bifidobacterium pseudolongum alleviates chronic intermittent hypoxia-induced cognitive impairment by restoring acetate metabolism and suppressing hippocampal neuroinflammation and neuronal PANoptosis.\nAbstract: Obstructive sleep apnea, characterized by chronic intermittent hypoxia (CIH), is a common sleep disorder frequently accompanied by cognitive impairment. Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction. Targeting B.p and acetate may offer a promising therapeutic strategy for neuroprotection in OSA.\n\nID: 42048405\nTitle: Fecal microbiota transplantation mitigates respiratory infection in rats exposed to hypobaric hypoxia by modulating the NLRP3 inflammasome and mucosal immunity.\nAbstract: To investigate the role of the gut-lung axis in respiratory infection under hypobaric hypoxia and the therapeutic potential of fecal microbiota transplantation (FMT). Rats were exposed to hypobaric hypoxia (simulated 5000 m) for 14 days. Gut microbiota and serum short-chain fatty acids (SCFAs) were analyzed via 16S rRNA sequencing and GC-MS. Rats were then infected with Streptococcus pneumoniae and treated with FMT. Lung inflammation, NLRP3 inflammasome activity, cytokines, bacterial load, and secretory IgA (sIgA) were assessed. Hypobaric hypoxia triggered gut dysbiosis, marked by reduced abundance of Firmicutes D and Lactobacillus, elevated Bacteroidota, and decreased SCFA levels..FMT restored microbiota composition, increased acetic and butyric acid levels, and attenuated lung inflammation. FMT also enhanced NLRP3 inflammasome activation (NLRP3, ASC, Caspase-1), elevated IL-1\u03b2, IL-6, and TNF-\u03b1 in BALF, reduced bacterial colonies, and increased airway sIgA in infected rats. FMT alleviates hypobaric hypoxia-aggravated respiratory infection by restoring gut microbiota, modulating SCFAs, and enhancing NLRP3-mediated mucosal immunity, highlighting the gut-lung axis as a therapeutic target.\n\nID: 41977455\nTitle: Petasites japonicus Leaves Alleviate Depression in Dextran Sulfate Sodium-Induced Colitis Mice Through the BDNF/TrkB Pathway and Modulation of Inflammation.\nAbstract: Inflammatory bowel disease (IBD) is a chronic gastrointestinal disorder with a high incidence of anxiety and depression. However, the underlying mechanisms of these symptoms remain to be fully elucidated. This study investigated the effects and mechanisms of a 20% ethanolic extract of Petasites japonicus leaves (EPJ) on dextran sulfate sodium (DSS)-induced colitis and depression-like behaviors. The physiological compounds identified in the EPJ were citric acid, chlorogenic acid, caffeic acid, fukinolic acid, 3,5-dicaffeoylquinic acid, quercetin 3-O-\u03b2-D-glucose-6\u2033-acetate, 4,5-dicaffeoylquinic acid, kaempferol-3-O-(6\u2033-acetyl)-\u03b2-glucopyranoside, and pedunculoside. EPJ significantly alleviated DSS-induced colitis, as evidenced by improvements in body weight loss (87.41% vs. 76.02% in the DSS group), colon length (5.75 vs. 4.34 cm), intestinal permeability (52.80 vs. 163.01 \u03bcg/mL), and myeloperoxidase (MPO) activity (0.24 vs. 0.67 U/mg) (p < 0.05). Histological analysis further confirmed recovery of goblet cells and attenuation of muscle layer thickening. EPJ also reversed DSS-induced gut microbiota dysbiosis and contributed to the restoration of microbial homeostasis. Behavioral assessments showed that EPJ effectively ameliorated depression-like behaviors. EPJ improved antioxidant systems in colon and brain tissues by modulating malondialdehyde (MDA) levels and reduced glutathione (GSH) and superoxide dismutase (SOD) activity. EPJ further upregulated tight junction protein expression and suppressed TLR4/NF-\u03baB inflammatory pathway activation in both colon and brain tissues. Moreover, EPJ modulated serum stress-related hormones, normalized hypothalamic-pituitary-adrenal (HPA) axis dysregulation, regulated the BDNF/TrkB signaling pathway, and modulated tryptophan-kynurenine metabolism. Collectively, these findings suggest that EPJ exerts protective effects against DSS-induced colitis and depression-like behaviors.\n\nID: 41935130\nTitle: Protective effects of enteral acetate supplementation against brain injury in a rat model of necrotizing enterocolitis.\nAbstract: Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in preterm infants, often leading to brain injury. The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants.\n\nID: 41926238\nTitle: 2'-Fucosyllactose Alleviates Metabolic Hypertension in Mice via Gut Microbiota Modulation and Involvement of the LPS/TLR4 Signaling.\nAbstract: 2'-Fucosyllactose (2'-FL) shows promise in ameliorating metabolic disorders. However, the role of 2'-FL in metabolic hypertension (MH) remains unclear. This study aimed to evaluate the effects of 2'-FL on MH and explore its underlying mechanisms. 2'-FL treatment (1000 mg/kg) reduced systolic blood pressure (SBP) by 16.6% and alleviated dyslipidemia, microglial activation, and neuroinflammation in MH mice. 2'-FL markedly increased short-chain fatty acids (SCFAs)-producing beneficial bacteria, e.g., Akkermansia and Bifidobacterium by 3.9-fold and 19.5-fold, accompanied by increased fecal acetate and butyrate. Notably, the benefits of 2'-FL for MH were transferable via fecal microbiota transplantation (FMT). Particularly, 2'-FL-mediated attenuation of vascular dysfunction was associated with the inhibition of the lipopolysaccharide/toll-like receptor 4 (LPS/TLR4) signaling, a protective effect that could be transferred via FMT. The antihypertensive and metabolic benefits of 2'-FL in mice were accompanied by gut-brain axis modulation. These findings suggest that 2'-FL represents a promising dietary strategy for preventing hypertension-associated complications.\n\nID: 41903401\nTitle: Short-chain fatty acids, neuroinflammation, and autism spectrum disorders: A mechanistic systematic review.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social and communication deficits, repetitive behaviors, and cognitive alterations. Increasing evidence indicates that immune dysregulation, particularly neuroinflammation, is central to its pathophysiology. The gut-brain axis and microbial metabolites, especially short-chain fatty acids (SCFAs: butyrate, acetate, propionate), have emerged as potential modulators of these processes. SCFAs are absorbed from the gut and may modulate brain function via transporter-dependent mechanisms at the BBB, although evidence in ASD contexts remains limited, thereby allowing them to influence both peripheral and central immune responses. This qualitative systematic review included studies published between 2015 and 2025 addressing at least one of three links: (1) ASD and neuroinflammation, (2) ASD and SCFAs, and (3) SCFAs and neuroinflammation. Twenty studies met inclusion criteria and were analyzed. Findings indicate that SCFAs exert distinct effects: butyrate consistently shows neuroprotective and anti-inflammatory actions, acetate displays context-dependent dual effects, and propionate is mainly associated with detrimental outcomes, including social and cognitive impairments and elevated inflammatory markers. Overall, SCFAs may influence ASD pathophysiology through modulation of neuroinflammatory mechanisms, with effects depending on the specific SCFA, dosage, and context. Nutritional strategies that modulate SCFA production, such as dietary fiber enrichment, prebiotics, and probiotics, may offer feasible, non-invasive therapeutic approaches. However, clinical evidence remains limited and heterogeneous, highlighting the need for well-designed trials to determine optimal interventions targeting SCFAs in ASD.\n\nID: 41896724\nTitle: Circulatory dietary and gut-derived metabolites predict early cognitive decline.\nAbstract: A key component of disease prevention is the identification of at-risk individuals. Microbial dysbiosis in the early stages of cognitive decline and Alzheimer's disease (AD) and can modulate the levels of microbe-derived metabolites (MDM), thought to contribute to neuroinflammation, blood\u2012brain barrier dysfunction, and neuronal degeneration. However, the precise role of MDM in this process, as well as their potential value as risk factors, remains poorly understood. Mass spectrometry platforms determined the serum concentration of 33 metabolites (13 tryptophan-related compounds, 15 bile acid compounds, 3 TMAO-related metabolites and 2 cresol metabolites) from cognitively healthy subjects, subjective cognitive impairment (SCI) participants and mild cognitive impairment (MCI) participants (n\u2009=\u200950 per group, matched for age, BMI and sex). Multiple linear regression and machine learning techniques were applied to identify a metabolite panel capable of classifying early cognitive decline. 16S rRNA amplicon sequencing was employed to identify bacterial taxa associated with these metabolic changes. Multiple linear regression modelling, adjusted for sex, BMI, age, albumin (for its role in metabolite transport), liver and kidney function, and background diet, identified key neuroprotective metabolites, namely choline, 5-hydroxyindole acetic acid, and indole propionic acid (IPA), as lower in SCI and MCI individuals compared to healthy controls. In contrast, the cytotoxic metabolite, indoxyl sulfate, and kynurenic acid were elevated. A random forest algorithm with multiclass classification further validated these findings, highlighting six metabolites (indoxyl sulfate, choline, 5-hydroxyindole acetic acid, IPA, kynurenic acid, and kynurenine) as classifiers of early cognitive decline, achieving an area under the curve (AUC) of 0.79. These findings suggest that MDM may serve as putative composite biomarkers of early cognitive decline, offering potential clinical relevance for metabolic risk stratification and supporting the future development of minimally invasive screening tools.\n\nID: 41839449\nTitle: Resveratrol Attenuates Neuroinflammation and Gut-Brain Axis Dysfunction Induced by Lead and Cadmium Co-Exposure by Modulating Gut Microbiota in Rats.\nAbstract: Resveratrol (RSV), a dietary polyphenol widely present in traditional medicinal plants and foods, exhibits antioxidant and anti-inflammatory properties that are relevant to ethnopharmacological strategies for protecting against environmental neurotoxicants. Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin. RSV attenuated cytokine release, normalized goblet cells, reversed dysbiosis by restoring Lactobacillaceae/Prevotellaceae, and increased acetate, propionate, and butyrate. It reinstated 5-HT and GABA while reducing SP and restoring VIP across serum, colon, and hippocampus. RSV attenuated Pb-Cd-associated neurotoxicity and was accompanied by improved intestinal and BBB-related readouts, partial normalization of gut microbiota features and SCFA levels, and preservation of synaptic and neurotransmitter-related markers, consistent with a link to gut-brain axis function. This study is among the first to test RSV in a Pb-Cd co-exposure model using a multi-dose regimen with integrated behavioral, barrier, microbial, and neurochemical endpoints.\n\nID: 41761283\nTitle: Bacteroides coprocola protects dopaminergic neurons in rotenone-induced Parkinson's disease mouse model by modulating gut microbiota dysbiosis and inhibiting the NLRP3 signaling pathway.\nAbstract: Parkinson's disease (PD) is a prevalent neurodegenerative disease and its pathogenesis is still unclear. Emerging evidence supports the gut-origin hypothesis, highlighting gut microbiota dysbiosis as a contributing factor in PD pathogenesis. Our previous clinical study showed that Bacteroides coprocola (B. coprocola), a gut bacterium producing short-chain fatty acids (SCFAs), was significantly reduced in PD patients. This study was aimed to investigate the potential of B. coprocola in ameliorating PD pathology and explore the underlying mechanisms in a rotenone-induced PD mouse model. The rotenone-induced PD mouse model was treated by orally administering B. coprocola for three weeks. Immunofluorescence, Western blotting, flow cytometry, 16S rRNA sequencing, and metabolomics were performed to assess midbrain and intestinal changes, NLRP3 inflammasome activation, macrophage polarization, gut microbiota, and SCFA levels. In vitro, LPS-stimulated bone marrow-derived macrophages were used to validate the role of NLRP3 signaling in macrophage polarization following sodium acetate and sodium butyrate treatment via siRNA and molecular assays. B. coprocola treatment alleviated PD-related motor deficits, neuroinflammation, gut microbiota dysbiosis, and intestinal barrier permeability in the rotenone-induced PD mouse model. Mechanistically, B. coprocola reshaped the gut microbiota composition and modulated macrophage polarization, which were associated with the inhibition of the NLRP3 inflammasome signaling pathway. Furthermore, in vitro experiments confirmed that the acetate and butyrate-key metabolites of B. coprocola-attenuated the inflammatory responses and promoted M2-like macrophage polarization via free fatty acid receptor (FFAR) 2/3 receptors, thereby suppressing NLRP3 activation. In conclusion, B. coprocola treatment can improve motor deficits, neuroinflammation, and intestinal function in the rotenone-induced PD mouse model. The effects are associated with microbiota remodeling, regulation of macrophage polarization, and inhibition of the NLRP3 inflammasome pathway. Acetate and butyrate, key metabolites of B. coprocola, might play an important role in promoting M2 macrophage polarization through FFAR2/3 receptors.\n\nID: 41715194\nTitle: Akkermansia muciniphila reduces neuroinflammation and A\u03b2 deposition via tryptophan metabolism in the APP/PS1 mouse model of Alzheimer's disease.\nAbstract: Akkermansia muciniphila (A. muciniphila), a beneficial gut bacterium, has increasingly attracted interests in Alzheimer's disease (AD) research, its specific role in the microbiota-gut-brain axis still remains unclear. In this study, we demonstrated that A. muciniphila administration improve cognitive deficits and reduce amyloid-beta (A\u03b2) deposition in APP/PS1 mice, a transgenic model of AD. Subsequently, it is revealed that A. muciniphila administration significantly alters gut microbiota diversity and composition. Mechanically, our metabolomics analysis of cecal contents indicates A. muciniphila administration increases short-chain fatty acids (SCFAs) derived from the intestinal microbiota, including butyric acid and acetic acid. Significantly, in APP/PS1 mice with the A. muciniphila administration, targeted metabolomics identify that the production of 62 metabolites are increased such as indole-3-acetic acid (IAA), tryptophan, acetic acid and cinnamic acid, as well as aconitic acid and threonine, et al.; the production of 28 metabolites are decreased such as isoleucine and N-acetylneuraminic acid (NANA) as well as ornithine and docosapentaenoic acid (DPA), et al. It is also identified by cytokine analysis of plasma that A. muciniphila administration reduces peripheral pro-inflammatory cytokines interleukin-6 (IL-6), IL-1\u03b2, IL-17 and tumor necrosis factor-alpha (TNF-\u03b1), et al., whereas it increases anti-inflammatory cytokines, such as IL-4, IL-10 and IL-22, et al. There is no any change of other cytokines, such as interferon-gamma (IFN-g), IL-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF), et al. Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators. At the same time, A. muciniphila administration improves cognitive deficits, alleviates neuroinflammation and A\u03b2 deposition via AhR/NF-\u03baB/NLRP3 signaling pathway in APP/PS1 mice. In summary, our findings suggest A. muciniphila is a promising approach for preventing AD progression by microbiota-gut-brain axis.\n\nID: 41692443\nTitle: Xuefu Zhuyu Capsule alleviates depression in post-stroke depression model rats via modulation of the gut microbiota-gut-brain axis.\nAbstract: Xuefu Zhuyu Capsule (XFZY) demonstrated potential in alleviating post-stroke depression (PSD), a condition whose underlying mechanisms may involve the gut-brain axis. This study aimed to explore the therapeutic effects of XFZY on PSD and its possible modulation of the gut microbiota-gut-brain axis in a rat model. Wistar rats were randomly assigned to sham, PSD, three XFZY dose (0.216, 0.432, 0.864 g/kg), and fluoxetine (1.80 mg/kg) groups (n = 12 per group). The PSD model was established using transient middle cerebral artery occlusion (t-MCAO) combined with chronic unpredictable mild stress (CUMS), followed by 28 days of XFZY administration. In a separate experiment, gut microbiota was depleted via antibiotic cocktails, with rats divided into sham, PSD, XFZY medium Dose (XFM), pseudo-germ-free (PGF) and PGF + XFM (PGFX) groups. Behavioral tests indicated that XFZY ameliorated depressive-like behaviors, with the medium dose (0.432 g/kg) showing the most significant effect. Histological analysis using hematoxylin and eosin (H&E) and Nissl staining revealed that XFZY alleviated colonic and neuronal damage. Furthermore, 16S rRNA sequencing and gas chromatography revealed that XFZY modulated gut microbiota composition, increased species richness, and elevated levels of short-chain fatty acids such as acetic acid, propionic acid, and butyric acid. Enzyme-Linked Immunosorbent Assay (ELISA) results showed that XFZY reduced pro-inflammatory cytokines - interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1), while immunohistochemistry indicated enhanced intestinal barrier function and reduced neuroinflammation. Furthermore, after depletion of gut microbiota using antibiotic cocktails, these therapeutic effects of XFZY were abolished. In summary, XFZY may alleviate PSD by modulating the gut microbiota and regulating the gut-brain axis, offering a promising direction for future therapeutic research.\n\nID: 41683284\nTitle: Varietal Differences in Kidney Beans Modulate Gut Microbiota and Inflammation During High-Fat Diet-Induced Obesity in Male Mice.\nAbstract: Background: Obesity-associated inflammation arises from adipose dysfunction and intestinal disturbances, including altered microbiota and short-chain fatty acid (SCFA) metabolism. Beans (Phaseolus vulgaris) are rich in non-digestible carbohydrates and polyphenols, but whether kidney bean varieties differing in seed coat colour exert distinct effects on inflammation in obesity remains unclear. Objective: To determine whether supplementation of an obesogenic high-fat (HF) diet with white or dark red kidney beans modulates gut microbiota, SCFAs, and intestinal, systemic, and neuroinflammatory outcomes. Methods: Male C57Bl/6N mice (n = 12/group) were fed a basal diet (BD; modified AIN-93G), an HF diet (60% kcal from fat), or an HF diet supplemented with 15% cooked white (HF + WK) or dark red kidney beans (HF + DK) for nine weeks. Outcomes included cecal microbiota composition, predicted KEGG pathways with taxon contributors mapped with BURRITO (a tool for linking predicted microbial functions to contributing taxa), and SCFA-related pathways; cecal and fecal SCFA concentrations; colon histomorphometry and expression of gut barrier junction and inflammatory genes; serum cytokines and adipose hormones; and hippocampal inflammatory and barrier genes. Results: Mice consuming bean-supplemented HF diets had higher microbial diversity, enrichment of SCFA-producing taxa (Prevotella, Lactobacillus, Muribaculaceae), and lower obesity-associated genera versus HF alone (Mucispirillum, rc4-4). Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase in both bean groups versus HF and BD, and butyrate kinase in HF + DK versus BD. Bean supplementation attenuated HF-induced reduction of goblet cells and systemic interleukin (IL)-10. The HF + DK group had lower colonic tumour necrosis factor (TNF)-\u03b1 and partially attenuated hippocampal IL-6. SCFAs were inversely associated with systemic and neuroinflammatory markers in HF + DK mice. Conclusions: Kidney bean supplementation mitigated HF diet-induced intestinal, systemic, and neuroinflammatory disturbances in male mice, with microbiota and SCFA modulation. Further, dark red beans exerted stronger anti-inflammatory effects, highlighting the role of seed coat colour in bean-mediated obesity outcomes.\n\nID: 41679674\nTitle: The role of indole metabolites derived from gut microbiota in Parkinson's disease: A comprehensive review.\nAbstract: Emerging evidence suggests that Parkinson's disease (PD) extends beyond the brain and involves early disturbances along the gut-brain axis. Among the metabolites shaping this communication, bacterial products derived from tryptophan, particularly indole compounds, are gaining attention as key biochemical links between intestinal dysbiosis and neurodegeneration. Multi-omics studies consistently show a reduction in commensal bacteria capable of producing beneficial indoles and an enrichment of Enterobacteriaceae that redirect tryptophan catabolism toward toxic intermediates. This shift disrupts epithelial and blood-brain barrier function and amplifies inflammatory and oxidative stress pathways within the central nervous system. Protective metabolites such as indole-3-propionic acid (IPA), indole-3-acetic acid (IAA), indole-3-lactic acid (ILA), and indole-3-carbinol (I3C) exert antioxidant, barrier-stabilizing, and anti-inflammatory effects through receptors including the aryl hydrocarbon and pregnane X receptors. Conversely, uremic indoles such as indoxyl sulfate (IS) and p-cresyl sulfate (pCS) activate microglia and astrocytes, promote \u03b1-synuclein aggregation, and accelerate dopaminergic neuron loss. Together, these findings support a view of PD as a metabolic imbalance between neuroprotective and neurotoxic indoles. Understanding how microbial and host pathways regulate this balance may open opportunities for early diagnosis and targeted interventions that integrate metabolism, immunity, and neuroprotection.\n\nID: 41654311\nTitle: Beta-caryophyllene restores liver-brain axis integrity in thioacetamide-induced hepatic encephalopathy: Behavioral and molecular insights.\nAbstract: Hepatic encephalopathy (HE) is a severe neuropsychiatric complication of liver dysfunction, driven by hyperammonemia, oxidative stress, neuroinflammation, apoptosis, and endoplasmic reticulum (ER) stress, which disrupt the hepato-encephalic axis and impair cognition and motor functions. Despite its clinical burden, effective therapies that target this multi-organ pathology remain limited. \u03b2-Caryophyllene (BCP), an antioxidant and anti-inflammatory dietary sesquiterpene, has not been evaluated for its ability to modulate liver-brain crosstalk in HE. This study investigated the hepatoprotective and neuroprotective effects of BCP in a rat model of thioacetamide (TAA)-induced HE. Rats received TAA (200\u202fmg/kg, i.p.) for three days, followed by BCP (100-400\u202fmg/kg) for 14 days. A comprehensive evaluation included serum biochemistry, oxidative stress indices, inflammatory cytokines, apoptosis-related proteins, neurotrophic factors (BDNF), astroglial activation marker (GFAP), ER stress regulators (GRP78, IRE1, XBP1, PERK, CHOP, ATF6), histopathology, and behavioral outcomes. TAA caused severe hepatic and cerebral injury with elevated liver enzymes, oxidative and inflammatory mediators, ER stress dysregulation, pro-apoptotic signaling, reduced BDNF and GFAP, and impaired motor and exploratory behaviors. BCP treatment dose-dependently restored biochemical and molecular parameters, suppressed oxidative stress and neuroinflammation, normalized ER stress signaling, promoted anti-apoptotic pathways, preserved BDNF and maintained astroglial status as reflected by GFAP, and improved histoarchitecture. Importantly, moderate to high doses fully restored locomotor and exploratory activity, indicating coordinated protection across the hepato-encephalic axis. Here, for the first time, the BCP concurrently mitigates hepatic and cerebral pathology via oxidative, inflammatory, apoptotic, and ER stress pathways, supporting its translational potential as a dual hepatoprotective and neuroprotective candidate for xenobiotic-induced HE and related liver-brain disorders.\n\nID: 41606412\nTitle: Roseburia intestinalis Offers Vagus-Dependent Neuroprotection Against Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is characterized by dopaminergic neurodegeneration and increasingly associated with gut microbiota alterations. Roseburia intestinalis (R. intestinalis) is consistently reduced in PD; however, its functional contribution remains unknown. We performed two complementary mouse experiments using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model. In the primary intervention experiment, mice received live or heat-killed R. intestinalis, followed by behavioral assessments and multi-layer analyses, including immunofluorescence, western blotting, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, 16S rRNA sequencing, metabolomics, and transcriptomics. In a separate mechanistic experiment, subdiaphragmatic vagotomy was introduced to interrogate vagus-dependent gut-brain communication, with key behavioral and inflammatory endpoints assessed. Live R. intestinalis improved rotarod, pole, and grip strength performance and preserved tyrosine hydroxylase-positive neurons in the substantia nigra; however, these effects were not observed in the heat-killed group. Live R. intestinalis treatment also reduced glial reactivity, restored brain-derived neurotrophic factor expression, and maintained blood-brain barrier integrity. Systemically, R. intestinalis lowered serum lipopolysaccharide, tumor necrosis factor-\u03b1, and interleukin-6 levels; preserved colonic structure; and restored mucin-secreting goblet cell function. MPTP-induced dysbiosis was partially corrected. Metabolomic profiling revealed restoration of several acyl-carnitines and higher acetic acid levels. Transcriptomic analysis showed increased immediate early genes after MPTP, and the elevated c-Fos in the substantia nigra was partially normalized by R. intestinalis. Importantly, vagotomy abolished the central neuroprotective and anti-inflammatory effects but did not affect peripheral cytokine suppression, indicating both vagus-dependent and vagus-independent pathways. R. intestinalis supplementation alleviated motor impairments, reduced neuroinflammation, preserved dopaminergic neurons, and improved intestinal and metabolic alterations in mice with an MPTP-induced PD model. Its protective actions may involve both central and peripheral mechanisms, potentially including gut-brain communication pathways. R. intestinalis may be a promising candidate for microbiota-based strategies against PD.\n\nID: 41579799\nTitle: Dihydromyricetin improves DSS-induced colitis and behavioral disorders by regulating the microbiota-gut-brain axis balance and inhibiting the activation of NLRP3 inflammasome.\nAbstract: Patients with inflammatory bowel disease (IBD) commonly exhibit psychiatric symptoms, such as anxiety and depression. However, studies on drugs addressing the concurrent amelioration of these symptoms in this patient population are rare. Previous studies have suggested that dihydromyricetin (DHM) may show therapeutic potential for IBD. This study investigated the therapeutic effects of DHM on dextran sulfate sodium (DSS)-induced colitis and associated behavioral disorders in mice. The findings of the experiments indicated that DHM could ameliorate colitis symptoms, including changes in body weight, colon length, disease activity index (DAI) scores, and histopathological damage. Furthermore, DHM improved the behavioral impairments observed in colitis mouse model, as evidenced by results from the open field test, elevated plus maze test, and tail suspension test, along with hippocampal histopathological assessments. Molecular analysis revealed that DHM notably suppressed the activation of NLRP3 inflammasome and IL-1\u03b2 in both the colon and the hippocampus. DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation. DHM lowered the levels of IL-1\u03b2, tumor necrosis factor-\u03b1 (TNF-\u03b1), and lipopolysaccharide (LPS) in the serum. 16S rDNA sequencing results indicated that DHM could modulate DSS-induced gut microbiota dysbiosis, enriching various beneficial metabolic and neuromodulatory pathways. Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces. Network pharmacology analysis identified the central intersecting genes of DHM, ulcerative colitis (UC), and neuroinflammation. Differential gene expression analysis underscored IL-1 \u03b2 as a pivotal target for the co-occurrence of UC and psychiatric conditions. These findings imply that DHM may ameliorate DSS-induced colitis and concomitant behavioral disturbances in mice, underscoring its potential as a natural therapeutic agent for IBD accompanied by psychiatric comorbidities.\n\nID: 41470904\nTitle: From Microbiota to Metabolomics: How Corylus heterophylla Fisch. Male Flower Extract Shields Mice from Cognitive Decline.\nAbstract: Background/Objectives: Emerging evidence suggests that hippocampal neuroinflammation (HNF) drives cognitive decline via dysregulation of the microbiota-gut-brain axis. Corylus heterophylla Fisch. male flower extract (CFE), a flavonoid-rich by-product of hazelnut processing, presents a promising yet unexplored neuroprotective candidate. This study investigated the preventive effects and mechanisms of CFE against HNF-induced cognitive decline. Methods: In the present study, mice were pretreated with CFE (200 mg/kg) before the Lipopolysaccharide (LPS) administration. Cognitive function, inflammation, core pathology, neuroplasticity, gut microbiota and serum metabolites were assessed. The chemical composition of CFE was analyzed by UHPLC-MS and its direct immunomodulatory effects were investigated in BV2 cells. Results: Behavioral assessments demonstrated significant therapeutic efficacy. This was evidenced by the recovery from hippocampal damage, accompanied by reduced levels of core pathological markers (A\u03b21-42, Tau, p-Tau (Ser404), GSK-3\u03b2), decreased expression of pro-inflammatory mediators including IL-33, elevated levels of neurotrophic factors (BDNF and MAP2), and attenuated abnormal activation of astrocytes and microglia. The 16S rRNA analysis confirmed that CFE ameliorated gut microbial dysbiosis. Notably, CFE significantly increased the relative abundance of Muribaculaceae and Lachnospiraceae, while significantly decreased Staphylococcus and Helicobacter. Metabolomics revealed enhanced levels of \u03b1-linolenic acid (ALA), serotonin (5-HT) and acetic acid, which correlated positively with Muribaculaceae and Lachnospiraceae. Phytochemical analysis identified luteolin and kaempferol as the predominant flavonoids in CFE. In BV2 cells, CFE, luteolin and kaempferol shifted microglial polarization from the M1 phenotype toward the M2 phenotype. Conclusions: CFE alleviated HNF-induced cognitive decline by regulating microbiota-gut-brain axis and microglial M1/M2 polarization.\n\nID: 41421404\nTitle: Neuroprotective effects of Prosopis cineraria L. ameliorate Alzheimer's disease manifestations.\nAbstract: Prosopis cineraria is traditionally used to enhance cognitive function and manage mental disorders. Its stem bark is valued in ethnomedicine, but its potential anti-Alzheimer's disease (AD) effects are scientifically unexplored. This research has examined the neuroprotective effects of the ethyl acetate fraction of P. cineraria bark (Pc-EA) against AlCl3-induced AD pathology, focusing on behavioral, biochemical, histological, and molecular outcomes. Diseased rats were treated with Pc-EA (30, 100, and 300\u00a0mg/kg) for 42 days. Cognitive and affective functions were evaluated with behavioral tests on days 29-42. Biochemical assays measured oxidative stress and cholinesterase activity, while RT-PCR quantified neuroinflammatory markers. Histopathological examination was performed to evaluate the integrity of hippocampal regions. Bioactive compounds were identified by phytochemical profiling (HPLC, GC-MS), and molecular docking was performed to assess binding interactions with acetylcholinesterase. AlCl3 exposure impaired memory, augmented anxiety and depression-like behavior, elevated oxidative stress, AChE activity, and induced hippocampal neurodegeneration with upregulated BACE-1, Tau, Caspase-3, and NF-\u03baB alongside downregulated BDNF. These changes were reversed by Pc-EA (100\u00a0mg/kg), which enhanced cognitive function, restored antioxidant defense, inhibited AChE and neuroinflammatory markers, and maintained hippocampal architecture. Bioactive phytoconstituents (chlorogenic acid, kaempferol, quercetin), which exert anti-amyloidogenic, antioxidant, anti-inflammatory, and acetylcholinesterase inhibitory effects, were identified by HPLC and GC-MS, and their potential roles were corroborated via in silico validation. Pc-EA demonstrated multi-targeted neuroprotection in AlCl3-induced AD, which is consistent with ethnomedicinal claims. These findings indicate P. cineraria as a potential modulator of AD through antioxidant, anti-inflammatory, anti-amyloidogenic, and neurotrophic mechanisms.\n\nID: 41418957\nTitle: Hypoxic adaptation mechanism of polysaccharide from Agaricus bitorquis (Qu\u00e9l.) Sacc.Chaidam on gut microbiota in Tibetan Plateau population based on in vitro model.\nAbstract: The intercellular polysaccharides derived from Agaricus bitorquis (Qu\u00e9l.) Sacc. Chaidam (ABIPs) are macromolecules exhibiting significant biological activity and outstanding anti-hypoxia properties. However, the digestive traits of ABIPs within the intestinal microbiota and their adaptive mechanisms to hypoxia in high-altitude populations remain poorly understood. The objective of this study was to investigate the anti-hypoxia mechanism of ABIPs at the small-molecule level through the utilization of the in vitro fermentation model of intestinal flora and the cell hypoxia models. The results indicated that under conditions of hypoxic stress, the total amount of monosaccharides and uronic acids (MUAs) metabolized by ABIPs in the plateau group was comparatively high, predominantly mannose. Furthermore, the level of short-chain fatty acids (SCFAs) produced through their metabolism was also significantly higher than that of the plain group, with acetic-acid, propionic-acid, and butyric-acid constituting a relatively large proportion. Additionally, in the plateau group, the metabolism of ABIPs increased the abundance of Prevotella and Alloprevotella, while the abundance of Collinsella decreased notably. In contrast, the metabolites produced by ABIPs in the plateau group (mainly SCFAs) had a more pronounced inhibitory effect on the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) signaling pathway than in the plain group. Overall, ABIPs may enable cells to develop hypoxia tolerance by enhancing hypoxia-consuming metabolic levels, rebalancing the gut microbiota, and stabilizing the HIF-1\u03b1 signaling pathway, thereby protecting the body from hypoxia damage.\n\nID: 41387992\nTitle: Alterations in gut microbiota and associated metabolites in patients with chronic fatigue syndrome.\nAbstract: To investigate differences in gut microbiota composition and short-chain fatty acids (SCFAs) metabolism between patients with Chronic Fatigue Syndrome (CFS) and Healthy Controls (HC), and to explore their associations with the CFS pathogenesis. This case-control study included 80 subjects, comprising 40 patients with CFS and 40 age- and sex-matched HC. Fecal microbial community structure was analyzed using 16S rRNA gene high-throughput sequencing. Fecal SCFAs concentrations were quantified using Gas Chromatography-Mass Spectrometry (GC-MS). Spearman correlation analysis with false discovery rate (FDR) adjustment was performed to elucidate associations among gut microbiota, SCFAs, and clinical scores. Compared to the HC group, the CFS group exhibited reduced gut microbiota \u03b1-diversity (e.g., ACE, Chao1, Shannon indices, all P\u2009<\u20090.01) and significantly altered \u03b2-diversity (ADONIS, P\u2009=\u20090.006). After FDR adjustment, fecal levels of acetate, butyrate, isobutyrate, and isovalerate remained significantly lower in the CFS group (all q\u2009<\u20090.05). Differential abundance analysis revealed a significant reduction in key taxa including the phylum Firmicutes (q\u2009=\u20090.010), class Verrucomicrobiae (q\u2009=\u20090.038), order Clostridiales (q\u2009=\u20090.043), and families Rikenellaceae (q\u2009=\u20090.011) and Ruminococcaceae (q\u2009=\u20090.049). Spearman correlation analysis solidified functional connections: key SCFA-producing taxa (e.g., Faecalibacterium, Subdoligranulum, Ruminococcaceae) were positively correlated with butyrate levels (r\u2009=\u20090.52-0.56, all q\u2009<\u20090.05). Furthermore, reduced abundances of Rikenellaceae and Alistipes were associated with lower SF-36 scores (r\u2009=\u20090.26, q\u2009=\u20090.032) and higher fatigue scores (FSS/FS-14, r\u2009=\u2009\u2009-\u20090.28 to\u2009-\u20090.30, q\u2009<\u20090.05). Isovalerate levels were negatively correlated with FS-14 scores (r\u2009=\u2009\u2009-\u20090.307, q\u2009=\u20090.014). Among CFS patients, those with higher dietary fiber intake had significantly higher levels of acetate and isovalerate than those with lower intake (both q\u2009<\u20090.05). Patients with CFS exhibit significant gut dysbiosis and abnormal SCFA metabolism. The reduction in key SCFA-producing taxa, their positive correlations with SCFAs levels, and the negative correlations of both with fatigue severity solidify a functional link between gut microbial depletion, reduced SCFAs, and clinical symptoms in CFS. Higher dietary fiber intake may partially ameliorate SCFAs metabolic disturbances in CFS patients.\n\nID: 41366428\nTitle: Microbial production of short-chain fatty acids attenuates long-term neurologic impairment after traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) triggers persistent gut microbiome dysbiosis characterized by depletion of short-chain fatty acid (SCFA)-producing bacteria. However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease.\n\nID: 41317578\nTitle: Bilobalide isolated from Ginkgo leaf tea alleviates Parkinson's disease via suppressing neuroinflammation and remodeling gut microbiota.\nAbstract: Parkinson's disease (PD) is a prevalent neurodegenerative disorder with limited effective treatments. Ginkgo leaf tea (GLT), derived from the dried leaves of Ginkgo biloba, has long been consumed for its cardiovascular and neurological health benefits. However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases.\n\nID: 41314293\nTitle: Caloric Restriction Alleviates Anxiety-Like Behaviors by Mitigating Neuroinflammation and Insulin Signaling Dysregulation in a High-Fat Diet-Induced Obesity Mouse Model.\nAbstract: Caloric restriction (CR) is reported to promote longevity and improve metabolism in different species, such as rodents and flies. However, limited studies have examined the effects of CR on obesity-associated psychiatric disorders and the underlying mechanisms. This study aimed to investigate the effects of CR on obesity-associated anxiety-like behavior in mice fed on a high-fat diet (HFD) and elucidate the underlying mechanisms. Male C57BL/6 mice (n = 24) were randomized into the standard diet group and the HFD group (fed on an HFD for 8 wk to induce obesity). The mice in the HFD group (n = 16) were further randomized into the following 2 groups for an additional 4-wk dietary intervention: the HFD group and calorie-restricted HFD (HFCR) group (received 70% of the mean daily food intake in the previous 3 d). Mouse body weight, anxiety-like behaviors, peripheral insulin sensitivity, central insulin signaling, and fecal microbiota were assessed. HFCR effectively mitigated HFD-induced weight gain and insulin resistance, demonstrating significant reductions in final body weight (-28.0%), glucose area under the curve (-30.7%), and homeostasis model assessment of insulin resistance index (-58.8%) compared with the HFD group (P < 0.01). HFCR also significantly reduced anxiety-like behaviors in open-field and elevated plus maze tests (P < 0.05). Mechanistically, HFCR suppressed neuroinflammatory pathways by inhibiting NF-\u03baB activation and c-Jun N-terminal kinase phosphorylation, while concurrently improving central insulin sensitivity via the insulin receptor substrate 1/Akt pathway (P < 0.05). Furthermore, HFCR remodeled the gut microbiota profile and markedly increased fecal short-chain fatty acid concentrations, with acetic acid and propionic acid levels rising by 107.7% and 57.0%, respectively (P < 0.01). In summary, our data indicate that CR, even without a change in dietary composition, could attenuate HFD-induced anxiety symptoms by modulating the gut microbiota, suppressing neuroinflammation, and regulating the brain insulin signaling pathway in adult male obese mice.\n\nID: 41294874\nTitle: Valeric Acid: A Gut-Derived Metabolite as a Potential Epigenetic Modulator of Neuroinflammation in the Gut-Brain Axis.\nAbstract: The gut-brain axis (GBA) is a critical area of research for understanding the pathogenesis of neuroinflammatory and neurodegenerative diseases. Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA.\n\nID: 41278468\nTitle: Liqi Yangyin formula ameliorates CUMS-induced depression and comorbid constipation via ACE/FFAR2 modulation of the microbiota-gut-brain axis.\nAbstract: The gut-brain axis, involving bidirectional signaling between the gastrointestinal tract and the central nervous system. Clinical observations have shown that Liqi Yangyin (LQYY) can effectively relieve symptoms of depression accompanied by constipation. However, whether LQYY exerts its effects through gut-brain crosstalk remains to be elucidated. A chronic unpredictable mild stress (CUMS) protocol was employed to establish a mouse model. H&E and Nissl staining were used to examine pathological changes in the prefrontal cortex (PFC) and colon. The ultrastructure of the intestinal barrier was observed via transmission electron microscopy, while the expression of the blood-brain barrier tight junction proteins was quantified by Western blotting (WB). ELISA quantified inflammatory factors and serotonin (5-HT) levels. Immunohistochemistry, immunofluorescence, and WB analyzed IBA-1 and Free fatty acid receptor 2 (FFAR2) expression levels. Gut microbiota composition was analyzed via 16S rDNA sequencing, and SCFAs levels were quantified using UHPLC-TSQ Altis Plus. Additionally, in vitro studies using BV-2 cells involved treatments with acetic acid (ACE) and an FFAR2 antagonist, after which the expression of relevant indicators was assessed. Our results demonstrated that LQYY significantly ameliorated CUMS-induced behavioral changes and improved intestinal motility. These effects were associated with the restoration of gut microbiota balance and an increase in ACE levels. LQYY increased FFAR2 expression, leading to reduced neuroinflammation and enhanced colonic 5-HT secretion. Furthermore, LQYY protected intestinal and blood-brain barrier integrity and improved neuronal morphology in the PFC. In vitro studies confirmed that ACE suppresses microglial inflammation through upregulating FFAR2 expression, an effect that was attenuated by the FFAR2 inhibitor GLPG0974. These findings suggest that LQYY modulates the gut-brain axis through ACE/FFAR2, offering a promising therapeutic approach for depression and constipation.\n\nID: 41273628\nTitle: Oral Administrations of Short-Chain Fatty Acids or Probiotics Extend the Survival Times and Mitigate the Neuropathological Damages in the Scrapie-Infected Hamsters.\nAbstract: Prion diseases (PrDs) are fatal neurodegenerative conditions marked by brain spongiform degeneration, prion protein scrapie (PrPSc) accumulation, neuronal loss, and gliosis. Currently, there are no effective treatments or preventive measures for these disorders. This study evaluated the therapeutic potential of short-chain fatty acids (SCFAs) and probiotics on PrDs using hamsters intracerebrally inoculated with the 263K scrapie strain. Treatments included oral administration of SCFAs (sodium propionate, butyrate, acetate) and probiotics (Clostridium butyricum, Bifidobacterium infantis). Clinical symptoms were monitored, and samples from brains, feces, and sera were collected at various time points for analysis. Assessments covered PrPSc deposits, gliosis, neuroinflammation, SCFA-related elements, gut microbiota profiles via 16S rRNA sequencing, and fatty acid levels measured by LC-MS/MS. Although all infected animals eventually died, those treated with SCFAs and probiotics showed a significant delay in clinical symptom onset and extended disease course. There was a notable reduction in the progression of PrPSc deposits, gliosis, and neuroinflammation in treated groups. Additionally, the decrease in SCFA receptors GPR41 and MCT4, along with downstream proteins Nrf2 and HO-1 in the brain, was slowed. Gut microbiota analysis revealed more beneficial bacteria in the SCFA and probiotic groups compared to controls. However, no significant differences were observed in serum and fecal fatty acid levels among groups. Oral administration of SCFAs and probiotics post-prion infection can effectively delay disease onset and progression while mitigating neuropathological changes associated with prion diseases. These results suggest a promising, cost-effective dietary intervention strategy for managing PrDs clinically.\n\nID: 41254951\nTitle: The probiotic Limosilactobacillus fermentum CECT5716 enhances the antihypertensive response to hydrochlorothiazide in spontaneously hypertensive rats.\nAbstract: Limosilactobacillus fermentum CECT5716 (LC40) consumption reduces hypertension and improves endothelial dysfunction in spontaneously hypertensive rats (SHRs). The diuretic hydrochlorothiazide (HCTZ) lowers blood pressure in SHR but disrupts the gut microbiota balance. In this study, we investigated whether the LC40 could enhance the antihypertensive effects of HCTZ. Interestingly, we found that coadministration of LC40 with HCTZ potentiated the beneficial effects of HCTZ on endothelial dysfunction and blood pressure without altering plasma HCTZ concentrations or exacerbating electrolyte imbalances. These protective effects were associated with normalization of microbiota alterations, including a reduction in the Firmicutes/Bacteroidota ratio, suppression of lipopolysaccharide biosynthesis, and an increase in acetate-producing bacteria. Additionally, LC40 reduced intestinal pathology and endotoxemia. Furthermore, the HCTZ\u2009+\u2009LC40-treated rats exhibited reduced neuroinflammation and sympathetic activity, along with an immunoregulatory effect characterized by increased regulatory T cell infiltration and a reduction of vascular oxidative stress in the aorta. The beneficial effects of LC40 in HCTZ-treated rats appeared to be microbiota dependent, as they were replicated through fecal microbiota transplantation in germ-depleted normotensive rats. Our findings identify the gut microbiota as a novel therapeutic target to enhance the antihypertensive effects of diuretics. The coadministration of LC40 with HCTZ modulates immune responses, providing a promising strategy to improve hypertension management.\n\nID: 41192697\nTitle: Gut microbiome-derived tryptophan metabolites predict relapse in alcohol use disorder.\nAbstract: Relapse is common in alcohol use disorder (AUD), a condition that affects nearly 11\u00a0% of adults in the US. Excessive alcohol consumption causes gut dysbiosis, which may in turn alter the production of bacterial-derived tryptophan metabolites. These metabolites impact the intestinal enteroendocrine environment and modulate neuroinflammation. This can ultimately affect behavior. However, the role of bacterial-derived tryptophan metabolites in AUD is not well-understood. Thus, in this study, we enrolled 40 patients admitted for severe AUD (26 males, 14 females) to investigate whether bacterial-derived indoles could predict AUD relapse. Upon enrollment, alcohol use as well as depression and anxiety symptoms were assessed. Peripheral blood samples were collected and analyzed for cytokines, bacterial-derived as well as endogenous tryptophan metabolites, and hematological factors. At three months after discharge, 25 patients completed follow-up and were re-assessed for clinical symptoms to identify AUD relapse. Ten patients relapsed and 15 patients were in early remission. Two bacterial tryptophan metabolites, indole-3-carboxaldehyde (IAld) and indole-3-acetic acid (IAA), significantly predicted relapse versus remission using logistic regression models (p\u00a0=\u00a00.019, SGPV\u00a0=\u00a00, and p\u00a0=\u00a00.035, SGPV\u00a0=\u00a00 respectively). These findings remained significant after adjustment for age, sex, BMI, and when additionally adjusting for nicotine use and depression severity. Moreover, higher IAld levels correlated with increased serotonin levels (Pearson's R; 0.592, p\u00a0<\u00a00.001) and fewer white blood cells (Pearson's R; -0.318, p\u00a0<\u00a00.05) in all 40 patients. Our data indicate significant interactions between microbiome-derived metabolites and host metabolism, and that IAld specifically may have a protective role in AUD, potentially through serotonin modulation.\n\nID: 41177025\nTitle: Bisphenol-A at an environmentally plausible dose caused gut microbiota-led impaired cognitive performances in adult mice.\nAbstract: Omnipresent Bisphenol-A (BPA) exposure is linked to neurobehavioral deficits and gut dysbiosis. However, studies assessed its impact on cognitive performance at environmentally unrealistic doses. Nevertheless, the exact mechanism underlying the neurobehavioral phenotype, linking the role of gut microbiota is poorly understood. Here, we evaluated the effects of environmentally plausible dose of BPA-exposure on cognitive task performances with the functional analysis of gut metagenome to elucidate the role of microflora-gut-brain axis in behavioural regulation. Swiss albino mice were exposed to BPA for 5 weeks assessed for working and spatial navigation task performances. qRT-PCR based gene expression, histological investigation, gut permeability, molecular and biochemical markers of neuro-inflammation, leaky gut, oxido-nitrosative stress and 16\u202fs rRNA gene based metagenomics with functional analysis were performed. BPA exposure altered the cognitive task performances (mean difference for transfer latency in elevated plus maze 20.84\u202f\u00b1\u202f5.64\u202fsec in and -13.12\u202f\u00b1\u202f3.53 in Morris' water maze), changed serotonin levels (-70.95\u202f\u00b1\u202f21.43) and acetylcholinesterase activity (0.0032\u202f\u00b1\u202f0.0008), enhanced ileal permeability (12.36\u202f\u00b1\u202f3.56) and systemic and tissue level inflammation (increased brain LPS, TNF-a, IL-1b, IL-6 and circulating TNF-a and IL-1b), coupled with reduced SCFAs levels (acetate; 32.48\u202f\u00b1\u202f8.48, and butyrate; 28.16\u202f\u00b1\u202f9.86). Faecal microbial transplant cohort replicated similar behavioural, biochemical and molecular patterns, suggesting the role of gut-microbiota in the phenotype determination. Functional pathways prediction suggested altered serotonin, dopamine, SCFAs metabolism and LPS biosynthesis. BPA at a much lower but environmentally relevant dose altered the cognitive performances, which has potential linkage to gut-microbiota mediated pathways.\n\nID: 41160277\nTitle: Comprehensive chemical analysis of polyphenols in the ethyl acetate extract from the roots of Ephedra sinica Stapf and evaluation of its therapeutic effects on SU5416/hypoxia-induced pulmonary arterial hypertension rats.\nAbstract: Pulmonary hypertension (PH) is a deadly disease with limited treatment options and poor long-term survival, necessitating the discovery of novel therapeutics. Our previous study has revealed that dimeric proanthocyanidins (PACs) mainly existed in the ethyl acetate extract from the roots of Ephedra sinica Stapf (ERE), however, its therapeutic effects on SU5416/hypoxia-induced pulmonary hypertension (PH) rats remain elusive. In this study, column chromatography combined with UPLC-LTQ-Orbitrap-HRMS analysis was performed to comprehensively characterize polyphenols in ERE. The therapeutic effects of ERE were investigated using the SU5416/hypoxia rat model, in which the rats were injected with SU5416 (20 mg/kg), followed by a three-week hypoxia exposure (10% O2). Hemodynamic indicators determined by right heart catheterization, pulmonary arterial morphological changes assessed by histopathological analysis, cardiac function and pulmonary hemodynamics using echocardiography, as well as oxidative stress markers measured by corresponding kits were used to test the therapeutic effects of ERE. Moreover, 16S rRNA sequencing combined with untargeted metabolomics was employed to capture changes in gut microbiota and serum metabolites after ERE treatment. Comprehensive chemical analysis of polyphenols in ERE revealed various levels of proanthocyanidin monomers, dimers and trimers, especially A-type dimers. In vivo experiments showed that ERE decreased pulmonary arterial pressure, right ventricular hypertrophy, right ventricular free wall (RVFW) thickness and oxidative stress levels, increased pulmonary acceleration time (PAT) and alleviated pulmonary vascular remodeling in rats exposed to SU5416/hypoxia treatment. Meanwhile, ERE improved gut microbial dysbiosis and the disturbed glycerophospholipid metabolism. Collectively, this study presents the first report on the efficacy of A-type PACs from Ephedra sinica for the treatment of PH through regulating gut microbiota and host metabolism.\n\nID: 41123675\nTitle: Short-Chain Fatty Acids as a Therapeutic Strategy in Parkinson's Disease: Implications for Neurodegeneration.\nAbstract: Neurodegeneration involves the progressive deterioration of neuronal structure and function, leading to deficits in cognition, motor skills, and other neurological processes. Parkinson's disease (PD) is notably prevalent among neurodegenerative disorders, characterized by dopaminergic neurodegeneration, protein misfolding, and an inflammatory brain environment. Despite advancements in understanding its pathophysiology, PD and other neurodegenerative conditions still lack effective disease-modifying therapies. This shortfall highlights the need for novel, multifactorial approaches to treatment. Recent research has spotlighted the gut-brain axis as a significant player in neurological health, particularly through the activity of gut-derived short-chain fatty acids (SCFAs). These microbial metabolites, primarily acetate, propionate, and butyrate, are produced via the fermentation of dietary fibers and are vital for maintaining intestinal and neural homeostasis. SCFAs exert anti-inflammatory effects, preserve blood-brain barrier integrity, and modulate neurotransmitter systems. Among them, butyrate shows notable neuroprotective capabilities, including histone deacetylase inhibition and mitochondrial enhancement. Disruption in SCFA production has been associated with PD progression, further underscoring their relevance. This review explores the mechanistic roles of SCFAs in modulating neurodegeneration, with an emphasis on PD. SCFA-based strategies offer a promising adjunctive route to restoring microbial balance, mitigating neuroinflammation, and safeguarding neurological function in neurodegenerative disorders.\n\nID: 42486560\nTitle: Neuroprotective Mechanical Ventilation Strategies in Brain-Injured Patients.\nAbstract: Mechanical ventilation presents a unique challenge in acute brain injury, as lung-protective strategies may adversely affect cerebral physiology. Acute brain injury encompasses a heterogeneous spectrum of disorders with dynamic pathophysiology, precluding uniform ventilatory protocols. The concepts of ventilator-associated brain injury and brain-lung crosstalk underscore the bidirectional impact of mechanical ventilation on pulmonary and neuronal integrity, even in the absence of primary brain pathology but particularly when acute brain injury is present. This article summarizes current evidence on lung-protective ventilation and its cerebral effects, emphasizing high-risk populations. Future research should refine integrated brain-lung protective strategies tailored to each patient's physiologic profile.\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: 42463907\nTitle: The Exercise-CTSS-AD Axis: a novel framework for understanding exercise-induced neuroprotection in Alzheimer's disease.\nAbstract: Disease-modifying therapies for Alzheimer's disease (AD) targeting amyloid-\u03b2 and tau have consistently failed, highlighting the urgent need for innovative therapeutic strategies. Cathepsin S (CTSS), a lysosomal cysteine protease upregulated in AD, functions as a \"multifaceted disruptor\" that interconnects neuroinflammation, blood-brain barrier (BBB) dysfunction, and A\u03b2 metabolic dysregulation. Although exercise is a validated non-pharmacological intervention that mitigates AD pathology, its multi-target molecular mechanisms remain elusive. Here, we propose and substantiate the \"Exercise-CTSS-AD Axis\" hypothesis, positing that exercise confers neuroprotection by suppressing CTSS through synergistic anti-inflammatory, anti-aging, and metabolic regulatory pathways. Exercise-induced myokines and clearance of senescent cells inhibit CTSS transcription, while AMPK-TFEB axis activation enhances lysosomal function to repress CTSS enzymatic activity. This systemic CTSS suppression preserves BBB integrity, ameliorates microglia-driven neuroinflammation, and restores A\u03b2 homeostasis by reducing production and enhancing clearance. Our framework provides a unifying molecular explanation for the pleiotropic benefits of exercise, positions CTSS as a quantifiable biomarker for personalized exercise regimens, and supports an innovative combinatorial strategy: \"Exercise\u2009+\u2009low-dose CTSS inhibitors\" as a disease-modifying therapy for AD.\n\nID: 42420718\nTitle: Therapeutic Hypothermia for Neurological Injuries: Balancing Neuroprotection with Risks.\nAbstract: While the therapeutic potential of hypothermia for treating tissue damage has been investigated for over 90\u00a0years, its effectiveness is still debated. This review introduces the history of hypothermia in medicine first, followed by a description of cellular mechanisms behind its neuroprotective effects observed in animal studies and some clinical studies. The next section focuses on current cooling approaches/devices, as well as cooling parameters recommended by researchers and clinicians to maximize the benefits of hypothermia. Animal and clinical studies of implementing hypothermia for spinal cord and brain tissue injury are presented next. The outcomes in treating conditions like traumatic brain injury (TBI), spinal cord injury (SCI), stroke, and cardiopulmonary issues will be discussed in detail. The review also examines the risks and benefits of hypothermia, supported or disputed by clinical studies. Contributions from bioengineers in the research field are presented in the last section, with details of cooling device design and theoretical simulations. Ultimately, the review highlights that successful hypothermia treatment hinges on achieving targeted tissue cooling quickly after injury, with mild hypothermia often being proven as effective as deeper cooling, provided a slow rewarming rate is implemented.\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: 42400752\nTitle: Exerkine-Mediated Regulation of the NLRP3 Inflammasome in Neuroprotection: Mechanistic Insights and the Role of Exercise.\nAbstract: Neurodegeneration is a leading cause of long-term disability and cognitive impairment, and the aberrant activation of the NOD-like receptor protein 3 (NLRP3) inflammasome is closely implicated in its pathogenesis. The NLRP3 inflammasome, as a central mediator of inflammatory cascades, can, when excessively activated, promote neuroinflammation and glial polarization, induce neuronal death, disrupt the blood-brain barrier, suppress angiogenesis and neurogenesis, impair synaptic plasticity, and induce inflammaging, ultimately leading to neurodegeneration. Exerkines, including neurotrophic factors, adipokines, myokines, hepatokines, enzymes/coenzymes, metabolites, and miRNAs, can target the aberrant activation of the NLRP3 inflammasome, exerting neuroprotective effects. Exercise has attracted increasing attention for its benefits to brain health, as it can modulate the release and expression of numerous exerkines (such as BDNF, NGF, GDNF, APN, Chemerin, Apelin, Irisin, CX3CL1, HSP90, IGF-1, LCN2, SAA, SIRT1, lactate, and exosomal miRNAs), which, through the activation of specific kinases and downstream signaling pathways in the brain, precisely target the excessive activation of the NLRP3 inflammasome and thereby ameliorate neurodegeneration. This review summarizes and critically evaluates recent advances in the mechanistic roles of the NLRP3 inflammasome in the onset and progression of neurodegeneration, as well as in the molecular mechanisms by which exerkines regulate the NLRP3 inflammasome to ameliorate neurodegeneration, and in exercise interventions, providing a theoretical basis for the precise and targeted application of exercise in the prevention and treatment of neurodegeneration.\n\nID: 42390160\nTitle: The Role of Nrf2 in SIRT1-Mediated RGC Neuroprotection in Traumatic Optic Neuropathy.\nAbstract: Traumatic optic neuropathy (TON), often occurring in traumatic brain injury (TBI) patients, is characterized by optic nerve damage, retinal ganglion cell (RGC) loss, and vision loss. Upregulation of sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, reduces RGC loss and vision deficits in TON models, but mechanisms underlying these effects are not well understood. This study examined if Nrf2, a transcription factor that regulates antioxidant enzymes, helps mediate neuroprotective effects of SIRT1 in TON. Wild-type (WT) and Nrf2-deficient mice received an intravitreal injection with adeno-associated virus type 2 (AAV2) expressing an RGC-selective promoter-driven human SIRT1, green fluorescent protein (GFP), or Nrf2. TON was induced by repetitive mild head impacts, and vision was assessed by optokinetic responses (OKRs). RGCs from isolated retinas were immunolabeled with Brn3a antibodies and counted to quantify Brn3a+ RGC numbers. TON resulted in decreased Brn3a labeling and decreased OKR scores in AAV2/synuclein gamma (SNCG)/GFP-injected WT mice as compared with unimpacted mice; AAV2/SNCG/SIRT1 treatment attenuated this loss. This protective effect was absent in Nrf2-deficient mice subjected to TON, as these mice had significant decreases in Brn3a-labeled cells and OKR scores whether they received AAV2/SNCG/GFP or AAV2/SNCG/SIRT1 therapy. AAV2/SNCG/Nrf2-injected WT mice exhibited similar decreases in Brn3a labeling and OKR scores as AAV2/SNCG/GFP-injected WT mice. Nrf2 is implicated as an important downstream effector of SIRT1-mediated therapeutic effects given that Nrf2-deficient mice are unable to recapitulate the neuroprotective effects of AAV-based SIRT1 gene therapy. However, Nrf2 is not sufficient to induce similar neuroprotective effects when overexpressed selectively in RGCs. Results of this study define an important mechanism of SIRT1 gene therapy mediating RGC neuroprotection.\n\nID: 42378963\nTitle: Endogenous neuroprotection in vascular cognitive impairment and dementia.\nAbstract: Vascular cognitive impairment and dementia (VCID), affecting millions globally with 30% higher mortality than Alzheimer's disease, lacks effective pharmacotherapies. Microvascular dysfunction emerges decades before clinical symptoms, driving irreversible neurodegeneration once established. Clinical results show that nonpharmacologic interventions demonstrate greater effectiveness: three-fold greater cognitive improvement and five-fold enhanced functional outcomes versus pharmacotherapy, while avoiding adverse effects that affect 40% of patients receiving pharmacological treatments. These interventions orchestrate convergent mechanisms: vascular restoration (reversing vasoconstriction, augmenting perfusion), metabolic reprogramming (mitochondrial/glucose optimisation), neuroinflammation resolution, oxidative stress mitigation, and synaptic preservation. Exercise, neuromodulation, dietary modification, environmental enrichment and conditioning medicine activate multilevel endogenous repair mechanisms inaccessible to pharmacological targeting. This review presents a comprehensive mechanistic framework elucidating how nonpharmacologic strategies modulate interconnected vascular/non-vascular domains. It highlights emerging bioelectronic medicine as a promising disease-modifying therapy, establishing nonpharmacologic interventions as first-line strategies that reconceptualize VCID from intractable neurodegeneration to a preventable, potentially reversible, condition.\n\nID: 42356195\nTitle: Myelin Repair as a Neuroprotective Strategy for Multiple Sclerosis: From Bench to Bedside.\nAbstract: Multiple sclerosis (MS) is a neuro-inflammatory disease characterized by demyelination in the central nervous system (CNS). Although a substantial endogenous capacity for remyelination has been demonstrated, this process is frequently incomplete and exhibits marked intra- and inter-individual heterogeneity. Several factors influence the extent of spontaneous myelin regeneration, including age, sex, disease course, and lesion localization. Oligodendrocytes (OL), derived from oligodendrocyte progenitor cells (OPCs), are the principal myelinating cells of the CNS. The regenerative cascade involves several key stages, including OPC activation, recruitment, differentiation into oligodendrocytes (OL), and myelin deposition. This process is orchestrated in a spatiotemporal manner by a complex interplay of intracellular signaling pathways, genetic determinants, and dynamic microenvironmental cues, which together balance inhibitory and pro-remyelinating influences. Several lines of evidence indicate that chronically demyelinated axons are vulnerable to degeneration, whereas successful remyelination may confer neuroprotection. These observations underscore remyelination as a promising neuroprotective therapeutic target for preventing or slowing disability progression in MS, a condition in which gradual neuroaxonal degeneration is believed to underlie irreversible disability progression. In this review, we aim to bridge the gap between fundamental biological mechanisms of remyelination and their clinical relevance. We examine recent advances in in vivo techniques for assessing remyelination and discuss how these measures correlate with clinical and disability outcomes. In addition, we review recent clinical trials of remyelination-promoting therapies and analyze the challenges that have limited their advancement beyond phase II. Overall, we seek to provide a comprehensive overview of the remyelination process from bench to bedside, highlighting both the obstacles and the therapeutic potential of remyelination strategies in MS.\n\nID: 42353267\nTitle: Neuroprotection in Early Diabetic Retinal Disease Using Eyedrop Delivery.\nAbstract: Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis. Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.\n\nID: 42353204\nTitle: From Tradition to Translation: A Critical Appraisal of Bacopa monnieri for Neuroprotection from Preclinical and Clinical Perspectives and Challenges in Utilization.\nAbstract: Dementia, and more specifically Alzheimer's disease (AD), is a progressive neurodegenerative disorder that has become a growing health menace in the world with an escalation in incidence as well as enormous social and economic consequences. Existing pharmacological treatment including cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists are not very effective in reducing the symptoms and fail to prevent the disease process. The non-pharmacological treatment interventions such as diet, exercise and cognitive training have supportive effects and cannot be used as standalone treatments. Therapeutic gap has resulted in increased interest in complementary and alternative therapies, especially that of pleiotropic action of herbal medicines. Bacopa monnieri (BM) is an Ayurvedic herb that has historically been used to treat memory enhancement and now has both preclinical and clinical evidence supporting its ability to modulate neurotransmission, reduce oxidative stress and suppress neuroinflammation. However, such difficulties as low bioavailability, instability of the environmental factors, and variations in formulations restrict its clinical applicability. New technologies with a lot of potential such as microencapsulation technology can provide the solution to this problem by increasing stability, solubility, and targeted delivery of compounds that will increase treatment efficacy. This narrative review is a synthesis of the existing information on the pathogenesis of dementia, therapeutic approaches, and the effectiveness of BM as a complementary intervention. It points out links between traditional medicine and modern neuroscience, strengths and limitations of on-going evidence, gaps that need further research, such as long-term clinical trials, standardized formulations, and discovery of the role of BM in the gut-brain axis. BM is a prime example of how herbal medicines can be used as a complement to conventional treatment and play a role in multi-modal approaches aimed at reducing the cognitive impairment associated with dementia.\n\nID: 42348596\nTitle: Erythropoietin, transfusions, and outcomes of retinopathy of prematurity and brain injury in extremely preterm infants: A post hoc analysis of the Preterm Erythropoietin Neuroprotection Trial (PENUT).\nAbstract: Erythropoietin is perceived as both a neuroprotectant and a biomarker for hypoxic stress. To explore correlations between serum erythropoietin (Epo) concentrations, perinatal risk factors, red blood cell transfusions and recombinant human erythropoietin (rHuEpo) with outcomes including retinopathy of prematurity (ROP) and brain injury on magnetic resonance imaging (MRI) in extremely preterm infants. This is a post hoc analysis of data from the Preterm Erythropoietin Neuroprotection Trial of preterm infants born between 24 0/7 and 27 6/7 weeks gestation and randomized to placebo or rHuEpo treatment (N\u2009=\u2009941). Serum Epo concentrations were collected within 24 hours (baseline) and at 7, 9, and 14 days. MRI was obtained at 36 weeks postmenstrual age (N\u2009=\u2009220). Baseline Epo concentrations negatively correlated with gestational age, delayed cord clamping, and Apgar scores, and positively correlated with intraventricular hemorrhage and risk of death. Neither endogenous Epo at baseline nor trajectories from birth to 14 days were associated with ROP. In the placebo group, Epo at 1 week of life (r\u2009=\u20090.26, p\u2009=\u20090.033) and 2-week area under the curve (r\u2009=\u20090.28, p\u2009=\u20090.019) positively correlated with white matter injury. In the treatment group, Epo at 14 days negatively correlated with white matter injury (r\u2009=\u2009-0.35, p\u2009=\u20090.004). Grey matter injury negatively correlated with baseline Epo in the placebo group (r\u2009=\u2009-0.27, p\u2009=\u20090.01) but positively correlated in the treatment group (r\u2009=\u20090.23, p\u2009=\u20090.047). Transfusions were associated with severe ROP (p\u2009<\u20090.0001) and total brain injury on MRI (p\u2009=\u20090.007). Transfusion volumes in the first week of life were associated with a greater risk of severe ROP in males (p\u2009=\u20090.0006). Endogenous Epo concentrations in preterm infants are influenced by perinatal variables and correlate with poor outcomes. The association of Epo with MRI results differed between placebo and rHuEpo treatment groups. Transfusions were associated with increased ROP and brain injury on MRI.\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: 42335514\nTitle: Bacoside-A from Bacopa monnieri (L.) Wettst. in Parkinson's disease: In Silico and preclinical insights into dopaminergic neuroprotection.\nAbstract: Parkinson's disease (PD) presents a formidable therapeutic challenge rooted not in a singular pathogenic event but in the convergent failure of mitochondrial homeostasis, redox balance, \u03b1-synuclein proteostasis, autophagy-lysosomal integrity, and neuroinflammatory amplification within substantia nigra dopaminergic neurons. Existing dopaminergic pharmacotherapies address symptomatic deficits while leaving the underlying neurodegenerative cascade unchecked, underscoring the need for disease-modifying strategies with multi-target mechanistic reach. This review examines bacoside-A, the principal triterpenoid saponin complex of Bacopa monnieri (L.) Wettst., as a structurally distinctive, polypharmacological neuroprotective scaffold whose biological relevance emerges from convergence with core vulnerability pathways driving dopaminergic degeneration. Integrating in silico, in vitro, and in vivo evidence, we examine how bacoside-A engages molecular targets including \u03b1-synuclein aggregation intermediates, monoamine oxidase-B, LRRK2 kinase, PINK1-Parkin mitophagy regulators, and the redox sensor DJ-1, with computational predictions providing a coherent mechanistic framework for findings observed across MPP\u207a-, rotenone-, and 6-OHDA-based preclinical models, including attenuation of mitochondrial dysfunction, oxidative amplification, and apoptotic signalling, and partial nigrostriatal preservation with motor improvement in vivo. This review reframes bacoside-A as a stress-buffering, network-active modulator most relevant during early, pre-degenerative disease stages. While no clinical trial has yet evaluated bacoside-A in PD, and findings from cognitive or other non-PD indications cannot be extrapolated as efficacy evidence, the convergent mechanistic, computational, and preclinical evidence presented here provides a strong rationale for advancing bacoside-A toward systems pharmacology-guided preclinical and clinical evaluation as an adjunct neuroprotective candidate.\n\nID: 42329291\nTitle: Targeting mitochondrial dysfunction and neuroprotection in neurodegenerative disorders: emerging therapeutic potential of berberine and polymeric nanoparticle-based delivery systems.\nAbstract: Major neurodegenerative disorders, such as Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis, are pathologically driven by mitochondrial failure and persistent neuroinflammation. Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique.\n\nID: 42325092\nTitle: Microglial SWELL1 deficiency drives male-specific seizure vulnerability but paradoxical neuroprotection through impaired phagocytosis.\nAbstract: The discovery of genes encoding the volume-regulated anion channel (VRAC) has enabled detailed exploration of its cell type-specific roles in the brain. LRRC8A (SWELL1) is the essential VRAC subunit. We observed seizure-induced, subunit-specific changes in microglial VRAC expression and investigated its function using conditional KO (cKO) of LRRC8A in microglia. SWELL1 cKO mice exhibited a male-specific increase in kainate-induced seizure severity, yet showed paradoxical neuroprotection against seizure-associated neuronal loss. Mechanistically, SWELL1 deletion led to a cell-autonomous reduction in microglial density and decreased release of VRAC-permeable neuroactive metabolites, including taurine, GABA, and glutamate in culture. Additionally, impaired phagocytic kinetics and reduced lysosomal biogenesis contributed to the observed neuroprotection. These findings reveal potentially novel roles for microglial VRAC in regulating seizure outcomes and microglia-neuron interactions.\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: 42320692\nTitle: Modulating inflammasome (NLRP3) activation and stress granule (SG) formation: Insight of neuroprotection by Normobaric oxygen (NBO) in ischemic stroke.\nAbstract: NBO therapy has demonstrated a neuroprotective effect on ischemic stroke. This study investigated the role of HIF-1\u03b1 in regulating SG formation and NLRP3 inflammasome activation following I/R injury in NBO-induced neuroprotection. A total of 137 adult male SD rats underwent 2\u00a0h of MCAO, followed by 2, 6, 24 or 48\u00a0h of reperfusion. NBO (95% O\u2082 at 2\u00a0l/min) was administered for 2\u00a0h at the onset of reperfusion. HIF-1\u03b1 inhibitor (YC-1) was administered 2\u00a0h before MCAO. Brain damage was assessed by infarct volumes (TTC staining), LDH and ROS levels (ELISA), and apoptotic and pyroptosis cell death (flow cytometry and TUNEL assay). Gene and protein levels of HIF-1\u03b1 and inflammasome related factors (IL-18, IL-1\u03b2, NLRP3, cleaved-Caspase-1, GSDMD-N, ASC, TXNIP) were analyzed. SG proteins levels (G3BP1, TIA-1) and DDX3X were detected by Western blot. Co-IP detected the interaction between DDX3X and G3BP1 or NLRP3. Infarct volume, LDH expression, ROS levels, and cell death (apoptosis and pyroptosis) were significantly increased after I/R injury. NBO and YC-1 treatments significantly reduced infarct volume, LDH and ROS levels, and cell death at 24 and 48\u00a0h of reperfusion. NBO suppressed the expression of inflammasome-related markers (IL-1\u03b2, IL-18, NLRP3, TXNIP, ASC, cleaved-Caspase-1, GSDMD-N) at both mRNA and protein levels. Co-IP analysis showed that I/R enhanced the interaction between DDX3X and NLRP3, which was suppressed by NBO and YC-1. NBO increased SG formation by regulating G3BP1 and TIA-1 expression and strengthened the interaction between DDX3X and G3BP1. NBO\u00a0+\u00a0YC-1 did not show additive effects, indicating that the two treatments act through the same HIF-1\u03b1-dependent pathway. NBO exerts strong neuroprotection against ischemic stroke by inhibiting HIF-1\u03b1-mediated NLRP3 inflammasome activation and enhancing SG formation via DDX3X-G3BP1 interaction. This study identifies HIF-1\u03b1 as a key mediator of post-ischemic inflammation and stress response, highlighting NBO as a potent, mechanism-based therapeutic in ischemic stroke.\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: 42309440\nTitle: Plant-based neuroprotection against memory impairment: Insights from Drosophila melanogaster models of neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterised by the progressive dysfunction of neurons, and memory impairment is one of their most debilitating clinical manifestations. The etiopathogenic mechanisms are multifactorial, such as protein misfolding, oxidative stress, and mitochondrial malfunction and synaptic degeneration along with neuroinflammation. As yet, therapists still focus mainly on symptomatic treatment and no agents are found to halt or reverse the decline of cognitive, indicating what is more needed is other kinds of neuroprotective strategy. In this context, the plant-derived phytochemicals stand out as promising candidates owing to their multi-targeted mode of action, favourable safety profile and long-standing use in traditional medicine systems. These bioactive compounds modulate oxidative stress, inflammatory signalling, neurotransmitter balance, apoptotic pathways and protein aggregation to elicit neuroprotection. The attention of the research community has also turned towards using Drosophila melanogaster as a model system for neurodegenerative-related studies due to its genetic tractability, accessible behavioural learning and memory tests, and the evolutionary conservation of potentially important biological pathways. This review consolidates recent evidence regarding plant-based neuroprotective strategies against memory impairment, with a specific focus on mechanistic mechanisms elucidated from Drosophila models of neurodegenerative diseases. Integrating findings across molecular, cellular and behavioural levels, the review illustrates the therapeutic promise of phytochemicals and reaffirms Drosophila as a valuable preclinical tool. It also addresses practical translational considerations, such as bioavailability, standardisation, and clinical validation, and sets forth future directions for effectiveness of plant-based interventions to facilitate improvements out in the real world.\n\nID: 42309244\nTitle: PPAR\u03b1 activation with fenofibrate confers hippocampal neuroprotection but lacks disease-modifying efficacy in chronic temporal lobe epilepsy.\nAbstract: Activation of peroxisome proliferator-activated receptor alpha (PPAR\u03b1) suppresses neuroinflammation and may interrupt epileptogenesis. We tested whether early intervention with the PPAR\u03b1 agonist fenofibrate exerts disease-modifying effects in the chronic phase of the lithium-pilocarpine model of temporal lobe epilepsy. Male Wistar rats received fenofibrate (100\u202fmg/kg, i.p., daily for 15 days) initiated 1\u202fh after status epilepticus. Outcomes were assessed 1-3 months later. Fenofibrate significantly attenuated neuronal loss in the dorsal CA1 subfield and ventral hilus of the hippocampus, partially reduced astrogliosis in the hilus, and decreased the proportion of amoeboid microglia in CA1. Behaviorally, fenofibrate prevented the TLE-induced reduction in risk-assessment exploration in the elevated plus maze, without affecting general locomotion or anxiety. Critically, fenofibrate did not alter the incidence of spontaneous recurrent seizures, interictal spike frequency, or the pathological reduction in delta and theta EEG power. It also failed to normalize the aberrant cortical response to pentylenetetrazol or reduce seizure severity. These findings demonstrate that early PPAR\u03b1 activation confers region-restricted neuroprotection and modest behavioral benefit, but does not suppress the core pathophysiological features of chronic epilepsy. The results dissociate neuroprotection from antiepileptogenesis and caution against assuming that anti-inflammatory interventions alone are sufficient for disease modification in temporal lobe epilepsy.\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: 42289235\nTitle: Nao Tan Qing exerts neuroprotection against traumatic brain injury via multi-targeted immunomodulation and neurorestoration.\nAbstract: Traumatic brain injury (TBI) is a devastating neurological disorder with long-term functional deficits and limited effective therapies, where secondary injury driven by dysregulated immunity and disrupted signaling is pathogenic; Nao Tan Qing (NTQ), a Chinese herbal formula guided by the traditional principle of \"resolving phlegm and inducing resuscitation\" for \"brain collateral obstruction\", shows neuroprotective potential, but its role and mechanism in TBI treatment remain unclear. This study aimed to systematically investigate the neuroprotective effects of NTQ against TBI model mice and elucidate its underlying molecular mechanisms. A controlled cortical impact (CCI) mouse model of TBI was established, and animals received NTQ treatment for 28 consecutive days. NTQ's neuroprotective efficacy was comprehensively evaluated via behavioral tests (functional recovery), cerebral blood flow imaging (vascular integrity), and electromyography (neural activity). Post-treatment inflammatory levels in TBI mice were assessed by quantifying inflammatory cytokine expression using quantitative real-time PCR and detecting microglial activation via immunofluorescence. Mechanistic exploration integrated network pharmacology, transcriptomics and bioinformatics analyses to identify NTQ's active components, potential targets, and associated pathways in TBI. In vivo experiments demonstrated that NTQ significantly improved behavioral outcomes, restored cerebral blood flow, and enhanced neural activity in TBI mice. Concurrent with these functional benefits, NTQ robustly suppressed neuroinflammation, as evidenced by reduced pro-inflammatory cytokine expression and attenuated microglial activation. Integrated network pharmacology and transcriptomic analyses confirmed that NTQ acts primarily through immune regulation after TBI, modifying key immune-related molecules and pathways. Specifically, NTQ intervention elicited pronounced downregulation of immune-inflammatory mediators, including Cd3g, Cd5, Cd8a, Epcam, Slamf7, Il16, Il17r, Il18rap, Cxcl9, Cxcr6, Tnfsf11, and Tnfsf15. Further mechanistic dissection identified six putative bioactive constituents of NTQ, including nicotinamide, curcumin, baicalin, chrysin, daidzein, and apigenin, which may remodel the intracerebral immune microenvironment after TBI through three core pathways: amine ligand-binding receptors, nuclear receptor meta-pathways, and arachidonic acid metabolism. Taken together, our integrated analyses demonstrate that NTQ exerts neuroprotective effects in TBI by modulating immune responses and suppressing neuroinflammation, thereby establishing NTQ as a promising multi-target therapeutic agent for TBI.\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: 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: 42268366\nTitle: Unlocking Neuroprotection: Exercise-Induced Muscle Secretome (Myokines) as a Therapeutic Avenue Against Alzheimer's Disease Pathogenesis.\nAbstract: This review critically evaluates exercise-induced myokines as neuroprotective agents against Alzheimer's disease (AD) and is structured around three thematic sections: (1) mechanistic foundations of myokine neuroprotection, (2) translational barriers to therapeutic development, and (3) a strategic framework for future research. Epidemiological studies associate physical exercise with reduced AD risk (30-45%), yet mechanisms remain incompletely resolved. Preclinical studies demonstrate that exercise-induced myokines (Irisin, BDNF, Cathepsin B) modulate AD pathology by: (1) attenuating amyloid-beta (A\u03b2)/tau accumulation, (2) suppressing neuroinflammation, and (3) enhancing synaptic plasticity. However, human exercise interventions show conflicting results influenced by APOE genotype, age, and exercise modality. Associative human data suggest that Interleukin-6 (IL-6) exemplifies pleiotropy-affording neuroprotective effects in acute contexts but potentially detrimental effects in states of chronic inflammation. Therapeutic hurdles include blood-brain barrier (BBB) penetration, pleiotropic risks, and patient heterogeneity. Emerging concepts such as combinatorial approaches (nanocarriers, exercise mimetics) and biomarker-driven trials are proposed as hypothetical future strategies; however, these remain unvalidated and require substantial preclinical development before implemented in clinical care. This narrative review is structured around three thematic sections: mechanistic foundations of myokine neuroprotection, translational barriers to therapeutic development, and a strategic framework for future research. The muscle-brain axis represents a compelling but complex therapeutic target. Based on current preclinical and correlational human evidence, future research should prioritize mechanistic rigor, standardized biomarker validation, and clinically viable delivery strategies. Notably, several approaches discussed herein-including nanocarrier delivery systems, exercise mimetics, and combinatorial myokine cocktails-remain speculative and are presented as future research directions rather than established therapeutic interventions.\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: 42252031\nTitle: Neuroprotection by lactate in Parkinson's disease: A novel anti-inflammatory mechanism via 14-3-3 protein lactylation.\nAbstract: Novel therapeutic strategies for Parkinson's disease (PD) are urgently needed. Neuroinflammation is a critical driver of disease progression and represents a promising target for intervention. Emerging evidence highlights lactate as a signaling metabolite that regulates inflammatory responses through protein lactylation. Given the involvement of 14-3-3 proteins in PD pathogenesis, we investigated whether lactate confers neuroprotection by promoting 14-3-3 lactylation and modulating neuroinflammatory signaling in PD. A rat model of PD was induced by subcutaneous injection of Rotenone (ROT) into the dorsal cervical region. Lactate was administered intracerebroventricularly. Motor function was assessed using open field, grid, and suspension tests. TH-positive neurons in the substantia nigra were evaluated by immunohistochemistry. The lactylation of 14-3-3 proteins and their interaction with NLRP3 were examined by co-immunoprecipitation (Co-IP). Mitochondrial localization of GSDMD was visualized by immunoelectron microscopy. The cytosolic mtDNA was assessed using qPCR. NLRP3 inflammasome components, the cGAS-STING pathway, and mitochondrial GSDMD were analyzed by western blotting. Levels of inflammatory cytokines and cGAMP were quantified by ELISA. Lactate ameliorated motor deficits and dopaminergic neuron loss in ROT-treated rats. Lactate increased 14-3-3 lactylation and enhanced 14-3-3 binding to NLRP3, accompanied by reduced NLRP3 inflammasome activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppressed cGAS-STING pathway activation. Lactate exerts neuroprotective effects in PD through a mechanism associated with enhanced 14-3-3 lactylation, reduced NLRP3/GSDMD pathway activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppression of cGAS-STING signaling.\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: 42224261\nTitle: Magnesium neuroprotection in retinal ganglion cells: A computational study of frequency-dependent therapeutic windows and intervention timing.\nAbstract: Retinal ganglion cells (RGCs) are vulnerable to excitotoxic damage mediated by excessive NMDA receptor activation and calcium overload. Extracellular magnesium (Mg2+) blocks NMDA receptors in a voltage-dependent manner, offering potential neuroprotection. However, the optimal Mg2+ concentrations and timing for effective intervention remain poorly defined. We developed a conductance-based computational model of an RGC incorporating Hodgkin-Huxley dynamics, AMPA and NMDA receptor-mediated synaptic transmission, and intracellular calcium dynamics. We systematically varied Mg2+ concentration (0.2-2.5 mM) and stimulation frequency (10-100 Hz) to identify therapeutic windows balancing neuroprotection with function preservation. At physiological frequencies (10-60 Hz), elevated Mg2+ reduced calcium (Ca2+) accumulation by 50-85% without affecting spike output. At excitotoxic frequencies (80 Hz), a narrow therapeutic window of 1.6-2.0 mM was identified, lying within a broader 1.4-2.0 mM spike-loss plateau (20% loss), where calcium additionally fell below the toxicity threshold while spike output was preserved. Intervention timing analysis revealed that Mg2+ protection efficacy is maximal with pre-treatment or immediate intervention (100%), and declines steeply with delay-reflecting the rapid early rise in Ca2+ rather than a fixed biological deadline (\u226550% protection requires intervention within 0.2 s in our abrupt-onset protocol; \u223c11% by 0.5 s). Re-analysis in terms of normalized Ca2+ progress revealed that the critical constraint for \u226550% protection is intervention before \u223c35% of peak Ca2+ accumulation-a state-based threshold reflecting relative phase sensitivity that generalizes across timescales. Sensitivity analyses confirmed robustness of the therapeutic window across physiologically plausible parameter ranges, and numerical validation demonstrated accuracy of the computational approach. These findings demonstrate that Mg2+-mediated neuroprotection is highly dependent on both concentration and timing, with implications for therapeutic strategies targeting glutamate excitotoxicity in glaucoma and retinal ischemia.\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: 42217987\nTitle: Neuroprotective strategies for retinal disease.\nAbstract: Neurodegenerative diseases of the retina result from diverse insults, including genetic mutations, metabolic deficiencies, vascular compromise, and inflammatory injury. These processes converge on dysfunction of the neurovascular unit, where neurons, glia, and vascular cells cooperate to maintain retinal health. Thus, neuroprotection must be considered in a broader context that incorporates support of glial and vascular elements in addition to neurons. In this chapter, we review both classical and emerging neuroprotective strategies in retinal disease. We summarize preclinical and clinical studies of trophic factor-based approaches, including ciliary neurotrophic factor (CNTF), brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), neurotrophin-3 (NT-3), fibroblast growth factor 2 (FGF2), insulin-like growth factor-1 (IGF-1), and transforming growth factor-\u03b2 (TGF-\u03b2), outlining mechanisms, efficacy, limitations, and safety. We also highlight nonclassical agents such as mesencephalic astrocyte-derived neurotrophic factor (MANF) and the lipid mediator erucamide, which act through distinct pathways to modulate stress responses and neurovascular stability. Additional approaches, including stem cell-based therapies, extracellular vesicles, metabolic supplementation, and lifestyle interventions, are discussed. Finally, we emphasize the importance of human-derived models such as retinal explants and organoids to overcome translational barriers. Collectively, these studies suggest that multimodal strategies may offer meaningful neuroprotection and preserve vision in progressive retinal disease.\n\nID: 42217976\nTitle: Neurodegeneration and neuroprotection in retinal detachment.\nAbstract: Retinal detachment (RD) occurs when the neurosensory retina separates from the retinal pigment epithelium (RPE). The most frequent type, rhegmatogenous retinal detachment (RRD), is caused by full-thickness retinal breaks that typically arise from vitreoretinal traction during posterior vitreous detachment. These breaks permit fluid to enter the subretinal space, leading to acute and often severe visual loss. Key risk factors include aging, myopia, pseudophakia, and the occurrence of posterior vitreous detachment. RRD constitutes a surgical emergency. Modern vitreoretinal procedures achieve high rates of anatomic reattachment; however, functional recovery remains highly variable. A major reason is that photoreceptor loss begins rapidly after detachment, driven by apoptosis, necroptosis, and inflammatory pathways, leading to irreversible damage even after successful surgical repair. This has stimulated interest in adjunctive neuroprotective strategies. Experimental and early clinical data suggest that repurposed agents such as tauroursodeoxycholic acid (TUDCA), ursodeoxycholic acid (UDCA), and iron chelators may preserve photoreceptor integrity. A multicenter randomized controlled trial (NCT06294847) is currently investigating oral UDCA in patients with macula-off RRD. Given that photoreceptor degeneration is a major determinant of limited visual recovery, combining surgery with neuroprotective therapies targeting cell-survival pathways may represent an important advance in improving postoperative visual outcomes.\n\nID: 42215107\nTitle: Bound polyphenols from seabuckthorn pomace alleviate sleep deprivation-induced cognitive impairment via gut microbiota-driven homovanillic acid-mediated neuroprotection.\nAbstract: Polyphenols exhibit potential neuroprotective activity. Seabuckthorn pomace bound polyphenols (SBP), as key bioactives from seabuckthorn, mainly contain ellagic acid, kaempferol, rutin, salvianolic acid A, and isorhamnetin. Chronic sleep deprivation (SD) leads gut microbiota dysbiosis and systemic inflammation, impairs neuronal and synaptic structural integrity, induces cognitive dysfunction, and increases the risk of neurodegenerative diseases. However, the ameliorative effects and underlying molecular mechanisms of SBP against SD-induced cognitive impairment remain unclear. The study investigated the improving effects and underlying mechanisms of dietary SBP supplementation on cognitive injury induced by chronic SD in mice. Behavioral results showed that 45\u00a0mg\u00b7kg-1\u00b7d-1 SBP significantly alleviated cognitive dysfunction in SD mice. Meanwhile, SBP ameliorated intestinal inflammation, gut microbial imbalance and tyrosine metabolism disorder, and markedly enriched beneficial bacteria including Bifidobacterium, Lactobacillus and Ligilactobacillus, with increased homovanillic acid (HVA) levels in feces, serum and brain. Furthermore, SBP attenuated SD-induced neuronal and synaptic damage and upregulated synaptic proteins SYN1 and PSD-95, which was associated with HVA-mediated inhibition of LC3/P62 autophagy pathway and activation of BDNF/TrKB pathway. Overall, SBP improves SD-induced synaptic damage and cognitive impairment via the gut microbiota-HVA-brain axis. These results position SBP can be used as a functional active factor in food development with memory-improving potential.\n\nID: 41762442\nTitle: In silico evaluation of bioactive compounds as potential inhibitors targeting HIF-1\u03b1/VEGFA/BACE1 pathway against Alzheimer's disease.\nAbstract: Neurodegenerative disorders such as Alzheimer's disease (AD) are characterized by progressive neuronal degeneration, predominantly caused by the accumulation of amyloid-beta (A\u03b2) and neuroinflammatory processes. Hypoxia, characterized by diminished oxygen levels, intensifies these mechanisms by stimulating hypoxiainducible factor 1-alpha (HIF-1\u03b1), potentially enhancing BACE1 enzyme activity and resulting in increased A\u03b2 synthesis and render neurons especially susceptible to hypoxia, exacerbating disease progression. Existing therapies are constrained by inadequate medication distribution across the blood-brain barrier and associated adverse effects. This study aims to identify potential therapeutic agents targeting HIF-1\u03b1, VEGFA, BACE1 key molecules involved in AD by exploring neuroprotective effects of bioactive compounds like benzyl isothiocyanate (BITC), Aurantiamide Acetate (AA), and galantamine, with the goal of developing more effective, targeted treatments. We used in silico screening, such as molecular docking and ADMET analysis, to assess the binding affinity, pharmacokinetics, and toxicity of potential inhibitors, followed by in\u00a0vitro testing. Results identified several compounds with strong binding affinities and favorable ADMET profiles as potential inhibitors of HIF-1\u03b1, VEGFA, BACE1 and experimental data support that hypoxia, via HIF-1\u03b1, upregulates BACE1, increasing A\u03b2 production and contributing to AD. Targeting these pathways may offer a multi-faceted approach to therapy, reducing neuroinflammation and amyloid pathology. In silico screening of potential molecules across different pathogenic pathways in Alzheimer's disease shows promise in developing successful therapeutic methods and continued validation may result in more tailored and safer medicines that address underlying neurodegenerative pathways.\n\nID: 41452361\nTitle: Neuroprotection by canagliflozin in a Huntington's disease model: role of HIF-1\u03b1 and PI3K/AKT signaling.\nAbstract: Huntington's disease (HD) is a progressive neurodegenerative disorder characterized by motor, cognitive, and metabolic dysfunction, largely driven by mitochondrial impairment and defective energy metabolism. Altered signaling through hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) and PI3K/AKT cascades contributes to neuronal vulnerability. Canagliflozin (Cana), a sodium-glucose cotransporter-2 inhibitor, has shown cognitive benefits in experimental studies. Here, we evaluated whether Cana mitigates 3-nitropropionic acid (3NP, 10\u00a0mg/kg, i.p., 14\u00a0days)-induced HD-like neurotoxicity in rats. Animals received Cana (5 or 10\u00a0mg/kg, p.o.) daily for 14\u00a0days, followed by behavioral assessments (open-field, Morris water maze, novel object recognition), histopathology, immunohistochemistry, and biochemical assays. Cana treatment significantly improved locomotor and memory performance, reduced striatal histopathological alterations, and attenuated GFAP immunoreactivity. Mechanistically, Cana upregulated HIF-1\u03b1 and downstream GLUT1/GLUT3/HKII, restored PI3K/AKT/CREB/BDNF signaling, and enhanced SIRT1/PGC-1\u03b1/Nrf2 antioxidant responses, while suppressing inflammatory mediators and caspase-3 activation. These findings highlight Cana as a promising disease-modifying strategy for HD by targeting both energy metabolism and pro-survival pathways.\n\nID: 41102470\nTitle: Closing the gap before using L-lactate to guide newborn care.\nAbstract: We thank the authors for their insightful commentary on our study investigating sodium L-lactate (NaL) supplementation in preterm infants with metabolic acidosis. Their analysis highlights lactate's expanding role beyond a metabolic byproduct, emphasizing its functions in cellular signaling, antioxidant defense, and neuroprotection. Our study demonstrated that NaL improved acid-base balance without adverse effects, likely through lactate's conversion to bicarbonate and potential support for mitochondrial function. The commentary further explores NaL's translational relevance in neonatal hypoxia-ischemia (NHI), where lactate may serve as a key neuroenergetic substrate and modulate inflammation and gene expression. While the Rice-Vannucci model has limitations, it remains valuable for long-term studies, as shown in our prior work. We agree that larger animal models offer enhanced physiological relevance but face practical constraints. Future research should compare NaL with sodium acetate (NaA), a standard in neonatal care, to assess relative benefits in correcting acidosis and supporting neurodevelopment. We support the call for randomized, multicenter studies with long-term follow-up to fully evaluate NaL's therapeutic potential in preterm and at-risk neonates. IMPACT: L-lactate is a key component of the astrocyte-neuron lactate shuttle, supporting brain energy metabolism. Ibrahim et al. suggest sodium L-lactate as an alternative maintenance fluid for preterm newborns. L-lactate should not be regarded merely as a simple fluid replacement. L-lactate acts as a signaling molecule, impacting cellular metabolism and brain development. Additional research is required to assess the potential benefits and safety of sodium L-lactate in newborns.\n\nID: 40405855\nTitle: Influence of Montelukast Combined With Methylprednisolone on Liver Function, Platelet Count, Eosinophil Count, and Myocardial Enzymes in Bronchopneumonia Children With Wheezing.\nAbstract: Aims/Background Bronchopneumonia is a common infectious disease in pediatrics, which can lead to myocardial and hepatic impairments. Children with bronchopneumonia accompanied by wheezing are vulnerable to hypoxia, which may damage other systems. Therefore, this study explored the influence of montelukast combined with methylprednisolone on liver function, platelet count, eosinophil count, and myocardial enzymes in children with bronchopneumonia accompanied by wheezing. Methods The clinical data of this retrospective study included 82 pediatric cases diagnosed with bronchopneumonia and wheezing between April 2022 and April 2024. Based on treatment methods, patients were divided into the methylprednisolone group (40 cases) as well as the montelukast and methylprednisolone group (42 cases). Therapeutic efficacy, resolution time of clinical symptoms, and adverse effects were recorded. Furthermore, liver function indicators, platelet count, eosinophil count, and myocardial enzyme levels were comparatively assessed using biochemical analyzer, hematology analyzer and biological kits in both groups. Results The total efficacy rate of the montelukast and methylprednisolone group was 95.2% (40/42), higher than the 77.5% of the methylprednisolone group (p = 0.018). Patients in the montelukast and methylprednisolone group had shorter hospitalization and clinical symptom disappearance times than the methylprednisolone group (both p < 0.05). In addition, there was no significant difference in total incidence of adverse reactions (p = 0.700). Methylprednisolone monotherapy or in combination with montelukast, substantially reduced liver function indicators, platelet count, eosinophil count, and myocardial enzyme levels (p < 0.05). Moreover, the platelet count, eosinophil count, and myocardial enzymes [aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase isoenzyme (CK-MB)] were reduced in the montelukast and methylprednisolone group compared to the methylprednisolone group after treatment (p < 0.05). Compared to the methylprednisolone group, alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL) levels were significantly diminished in the montelukast and methylprednisolone group following treatment (p < 0.05). Conclusion Montelukast and methylprednisolone combination therapy reduces platelet and eosinophil counts, alleviates myocardial and liver function damage, and demonstrates good therapeutic efficacy in children with bronchopneumonia accompanied by wheezing.\n\nID: 39923354\nTitle: Insomnia patients have a poor intestinal prognosis: Accompanied by microbiota-derived short chain fatty acids, diet and zonulin.\nAbstract: It is becoming increasingly clear that the relationship between sleep disturbance and gut microbiota metabolites is of great importance. This study aimed to examine the changes in microbiota metabolites, brain-derived neurotrophic factors and synaptic proteins in insomnia patients, with a particular focus on the impact of diet. A total of 41 patients with insomnia and 45 healthy individuals participated in the study. The Food Frequency Questionnaire was employed to ascertain the subjects' daily macronutrient intake over the previous month. Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to evaluate insomnia complaints. The concentration of faecal short-chain fatty acids (SCFAs) was quantified by gas chromatography. Serum zonulin, brain derived neurotrophic factor (BDNF), postsynaptic density protein 95 (PSD-95) and synaptophysin-like protein 1 (SYPL1) protein levels were quantified using an enzyme-linked immunosorbent assay (ELISA) method. The total SCFAs, acetic acid, propionic acid, butyric acid and valeric acid levels were found to be significantly lower in the insomnia patient group compared to the control group. The levels of zonulin, PSD-95 and SYPL1 were found to be significantly elevated in the insomnia patient group in comparison to the control group. A significant negative correlation was observed between PSQI and ISI values and fatty acids. It has been demonstrated that sleep deprivation may be associated with alterations in the metabolites produced by the gut microbiota. In Western countries where dietary fibre consumption is low, increasing SCFA levels, promoting gut integrity and homeostasis may be regarded as a promising new approach for the treatment of diseases such as insomnia.\n\nID: 39733474\nTitle: Estrogen Alleviates Oxidative Bowel Injury and Neuroinflammation in Necrotizing Enterocolitis.\nAbstract: High mortality and morbidity of neonates with necrotizing enterocolitis (NEC) necessitates the investigation of novel therapies to improve outcomes. It was aimed to elucidate the potential therapeutic effect of estrogen receptor agonists on NEC-induced intestinal and brain injury in rats. Sprague-Dawley pups of both sexes were separated from their mothers at postnatal 5th d. Feeding with formula along with a single session of hypoxia was applied to induce NEC, while control pups were kept with their mothers. The NEC rats received either vehicle, estrogen receptor \u03b1 (ER\u03b1) agonist propyl pyrazole triol (1\u00a0mg/kg/day), ER\u03b2 agonist diarylpropionitrile (1\u00a0mg/kg/day), or 17\u03b2-estradiol (1\u00a0mg/kg/day) during maternal separation. All pups were decapitated on postnatal 9th d to collect intestinal and brain tissue samples. Elevation in proinflammatory cytokines, apoptosis, and microscopically and biochemically evident oxidative injury in both the intestinal and brain tissues were observed in NEC-induced pups. In both the intestinal and brain tissues, nerve growth factor and brain-derived neurotrophic factor protein levels were depleted, expressions of both the ESR1 and ESR2 genes were downregulated, while treatment with 17\u03b2-estradiol or ER agonists alleviated extent of oxidative injury of the intestines and brain tissue, upregulated nerve growth factor, brain-derived neurotrophic factor, and ER gene expressions, abolished NEC-induced decrease in claudin-3 expression, increased the survival rates, improved the clinical states of the survived pups at varying degrees. Activation of estrogen signaling by receptor agonists alleviated NEC-induced intestinal and cerebral injury, implicating that estrogen agonists could be regarded as promising preventive/therapeutic agents for NEC.\n\nID: 39532223\nTitle: Exploring the mechanism of action of huoermai essential oil for plateau insomnia based on the camp/CREB/BDNF/gabaergic pathway.\nAbstract: The traditional Huoermai therapy is a treatment for insomnia used by the Tibetan people living on the Tibetan plateau in China. This therapy involves the use of Myristica fragrans Houtt. and Carum carvi L., along with fomentation and massage, and has shown significant clinical effects. However, the mechanism of how Huoermai therapy treats plateau insomnia needs further clarification. This study aimed to investigate the mechanism of action of Huoermai essential oil (HEO) in treating plateau insomnia, focusing on the cAMP/CREB/BDNF/GABAergic pathway. The major components of Huoermai essential oil were identified by Gas chromatography-mass spectrometry (GC-MS) for subsequent network pharmacology analysis. Proteomics techniques were employed to pinpoint disparities in brain tissue protein expression in a mouse model of plateau insomnia following Huoermai therapy administration, in conjunction with network pharmacology to forecast pathways related to hypoxia and insomnia. Plateau insomnia mouse model was established and the therapeutic impact of Huoermai essential oil was evaluated. Hematoxylin & Eosin staining(HE) was conducted to observe pathological damage to the cortex, hippocampus, thalamus and hypothalamus structures. Changes in serotonin (5-HT), melatonin (MT), adenosine (AD), cyclic adenosine monophosphate (cAMP) and malondialdehyde (MDA) levels in mouse brain tissue were gauged through enzyme-linked immunosorbent assay (ELISA) to assess sleep status and oxidative stress levels in mice. Molecular docking was employed to anticipate the target binding energy of Huoermai essential oil constituents. ELISA and Western Blot (WB) were used to ascertain the expression of cAMP/CREB/BDNF/GABAergic pathway. The results indicated that HEO positively impacted intermittent hypobaric hypoxia-induced plateau insomnia in mice. Histological examination results showed that HEO ameliorated neuronal damage in specific regions of the brain affected by plateau insomnia, such as the cortex, hippocampus, thalamus, and hypothalamus. Through GC-MS analysis, 56 volatile oil components were identified. Subsequently, a combined network pharmacology and proteomics analyses led to selecting the cAMP/CREB/BDNF/GABAergic pathway for further study. ELISA experiments demonstrated that HEO treatment increased GABA and MT levels while significantly reducing 5-HT and adenosine levels in brain tissue of mice with plateau insomnia. WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress. Moreover, molecular docking results showed strong binding affinity of all pharmacological components to their targets and proteins in the brain. These results indicate that HEO significantly prolongs sleep duration in plateau insomniac mice and treats plateau insomnia by modulating levels of sleep-related regulators, modulating the cAMP pathway, increasing GABA receptor expression, and improving neuronal survival and anti-apoptosis.\n\nID: 38057032\nTitle: Central obesity is detrimental to anti-inflammatory, phenotype, and exhaustion markers in mononuclear cells - A cross-sectional study.\nAbstract: To investigate the role of central obesity on immunometabolic response in peripheral blood mononuclear cells (PBMCs) from normal weight and overweight/obese young men. Eighteen individuals were classified as normal weight (NW; n\u00a0=\u00a09 - age: 25\u00a0\u00b1\u00a05 and BMI: 21.4\u00a0\u00b1\u00a01.7) and overweight/obese (OW; n\u00a0=\u00a09 - age: 29\u00a0\u00b1\u00a07 and BMI: 29.2\u00a0\u00b1\u00a02.7). The body composition was evaluated by dual-energy x-ray absorptiometry (DXA), waist circumference, and visceral and subcutaneous fat depots by ultrasound. Physical activity levels, metabolic parameters, immune phenotypic characterization, cytokine production by lipopolysaccharide (LPS) -stimulated whole blood cells and LPS or phorbol 12-myristate 13-acetate (PMA)-stimulated PBMC, and mitochondrial respiration in PBMCs were evaluated. Expression of AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma (PPAR-\u03b3), nuclear factor-kappa B (NF-\u03baB), toll-like receptor 4 (TLR-4), hypoxia-inducible factor-1 alpha (HIF-1\u03b1), and adrenergic receptor beta 1 and 2 (AR-\u03b21 and \u03b22) genes were evaluated in cultured PBMC using quantitative real-time polymerase chain reaction (qRT-PCR). Individuals with overweight/obese (OW) presented higher glucose (P\u00a0=\u00a00.009) and leptin (P\u00a0=\u00a00.010) than individuals with normal weight (NW). PBMCs of OW under stimulation with LPS presented a lower production of interleukin-10 (IL-10) (P\u00a0=\u00a00.011) and macrophage inflammatory protein-1alpha (MIP-1\u03b1) (P\u00a0=\u00a00.048) than NW. Mitochondrial respiration rates were not different between NW and OW subjects. Cultured PBMCs in LPS-stimulated condition indicated higher gene expression of AR-\u03b22 in OW, while PMA-stimulated PBMCs presented lower expression of AMPK (P\u00a0=\u00a00.002) and higher expression of NF-\u03baB (P=<0.0001) than NW. OW presented higher numbers of CD3+CD4+ T cells (P\u00a0=\u00a00.009) and higher expression of programmed cell death protein 1 (PD-1) in CD8+ T cells (P\u00a0=\u00a00.001) than NW. Central obesity promoted reductions in interleukin 10 production response and increase in AR-\u03b22 expressions in mitogen-stimulated PBMCs. Furthermore, central obesity altered the phenotype of PBMCs, also increasing the expression of PD-1 exhaustion markers in young adults.\n\nID: 37932046\nTitle: Low Glycolysis Is Neuroprotective during Anoxic Spreading Depolarization (SD) and Reoxygenation in Locusts.\nAbstract: Migratory locusts enter a reversible hypometabolic coma to survive environmental anoxia, wherein the cessation of CNS activity is driven by spreading depolarization (SD). While glycolysis is recognized as a crucial anaerobic energy source contributing to animal anoxia tolerance, its influence on the anoxic SD trajectory and recovery outcomes remains poorly understood. We investigated the effects of varying glycolytic capacity on adult female locust anoxic SD parameters, using glucose or the glycolytic inhibitors 2-deoxy-d-glucose (2DG) or monosodium iodoacetate (MIA). Surprisingly, 2DG treatment shared similarities with glucose yet had opposite effects compared with MIA. Specifically, although SD onset was not affected, both glucose and 2DG expedited the recovery of CNS electrical activity during reoxygenation, whereas MIA delayed it. Additionally, glucose and MIA, but not 2DG, increased tissue damage and neural cell death following anoxia-reoxygenation. Notably, glucose-induced injuries were associated with heightened CO2 output during the early phase of reoxygenation. Conversely, 2DG resulted in a bimodal response, initially dampening CO2 output and gradually increasing it throughout the recovery period. Given the discrepancies between effects of 2DG and MIA, the current results require cautious interpretations. Nonetheless, our findings present evidence that glycolysis is not a critical metabolic component in either anoxic SD onset or recovery and that heightened glycolysis during reoxygenation may exacerbate CNS injuries. Furthermore, we suggest that locust anoxic recovery is not solely dependent on energy availability, and the regulation of metabolic flux during early reoxygenation may constitute a strategy to mitigate damage.\n\nID: 37607495\nTitle: Effect of Leuprolide Acetate, a GnRH Agonist, on Neuroinflammation and Anxiety-Like Behavior after Mild Hypoxic-Ischemic Encephalopathy in Rat Model.\nAbstract: Mild hypoxic-ischemic encephalopathy (HIE) is a condition that predisposes to negative outcomes such as neuroanatomical injury, mood disorders, and motor or cognitive disabilities. The neuroinflammation plays an important role in the neurological damage; therefore, reducing it could provide neuroprotection. The leuprolide acetate (LA) has shown to have neuroregenerative and immunomodulator properties in other nervous system injuries. The aim of this study was to evaluate the immunomodulatory effect of LA in the acute phase of mild HIE and its effects in motor activity and behavior in a subacute phase. Forty-five Wistar rats on postnatal day 7 were divided into Sham, HIE treated with saline solution (HIE-SS), and HIE-LA. The HIE was performed cutting of the right carotid artery followed by 60 min of hypoxia. The expression of the inflammatory cytokines interleukin (IL)-1\u03b2, tumor necrosis factor (TNF)-\u03b1, interferon (IFN)-\u03b3, and the chemokine CXCL-1 were evaluated 72 h after HIE by RT-qPCR and the motor activity and behavior were evaluated by open field test at postnatal day 33. HIE-SS animals showed increased expression of IL-1\u03b2, TNF-\u03b1, IFN-\u03b3, and CXCL-1 genes in injured tissue. However, the HIE-LA group exhibited similar expression levels of IL-1\u03b2 and TNF-\u03b1 to the Sham group, while IFN-\u03b3 and CXCL-1 mRNA expression were attenuated with LA treatment. LA treatment also prevented anxiety-like behavior in the open field test. Treatment with LA partially reverses HIE-induced neuroinflammation and prevents anxiety-like behavior in neonatal rats.\n\nID: 36682600\nTitle: Delayed administration of Trichilia catigua A. Juss. Ethyl-acetate fraction after cerebral ischemia prevents spatial memory deficits, decreases oxidative stress, and impacts neural plasticity in rats.\nAbstract: Trichilia catigua A. Juss (Meliaceae) is used in Brazilian folk medicine to alleviate fatigue and emotional stress and improve memory. Previous studies from our laboratory reported that an ethyl-acetate fraction (EAF) of T. catigua that was given before cerebral ischemia in vivo prevented memory loss and reduced oxidative stress and neuroinflammation. Despite the value of these findings of a neuroprotective effect of T. catigua, treatment that was given immediately before or immediately after ischemia limits its clinical relevance. Thus, unknown is whether T. catigua possesses a specific time window of efficacy (TWE) when administered postischemia. Given continuity to previous studies, we investigated whether an EAF of T. catigua maintains its neuroprotective properties if treatment begins at different time windows of efficacy after ischemia. We also evaluated, for the first time, whether T. catigua possesses neuroplasticity/neurotrophic properties. Rats were subjected to transient global brain ischemia (TGCI) and then given a single dose of the EAF (400\u00a0mg/kg) or vehicle (1\u00a0ml/kg) orally 1, 4, or 6\u00a0h postischemia. The levels of protein PCG, GSH, and GSSG, and activity of SOD and CAT were assayed as markers of oxidative stress on the day after ischemia. In another experiment, naive rats underwent spatial learning training in a radial maze task and then subjected to TGCI. Delayed treatment with the EAF began 4 or 6\u00a0h later and continued for 7 days. Retrograde memory performance was assessed 10, 17, and 24 days postischemia. Afterward, brains were examined for neurodegeneration and neuronal dendritic morphology in the hippocampus and cerebral cortex. Another group received the EAF at 4\u00a0h of reperfusion, and 4 days later their brains were examined for GFAP and Iba-1 immunoreactivity. Lastly, ischemic rats received the EAF 4\u00a0h after ischemia and neural plasticity-related proteins, BDNF, SYN, PSD 95, and NeuN were measured in the hippocampus 7 and 14 days after ischemia. A single EAF administration 1, 4, or 6\u00a0h postischemia alleviated oxidative stress that was caused by ischemia, expressed as a reduction of the amount of the PCG and GSSG, normalization of the GSH/GSSG ratio, and the restoration of SOD activity. Ischemia caused the persistent loss of memory (i.e., amnesia), an outcome that was consistently ameliorated by treatment with the EAF that was initiated 4 or 6\u00a0h postischemia. The 4\u00a0h delay in EAF treatment positively impacted dendritic morphology in neurons that survived ischemia. TGCI reduced BDNF, SYN, PSD-95, and NeuN protein levels in the hippocampus and cerebral cortex. The EAF normalized SYN and PSD-95 protein levels. Ischemia-induced neurodegeneration and glial cell activation were not prevented by EAF treatment. The present study corroborates prior data that demonstrated the neuroprotective potential of T. catigua and extends these data by showing that the delayed administration of EAF postischemia effectively prevented memory impairment and decreased oxidative stress, dendritic deterioration, and synaptic protein loss within a TWE that ranged from 1 to 6\u00a0h. This specific TWE in preclinical research may have clinical relevance by suggesting the possible utility of this plant for the development of neuroprotective strategies in the setting of ischemic brain diseases. Another innovative finding of the present study was the possible neurotrophic/neuroplastic properties of T. catigua.\n\nID: 36338029\nTitle: Sodium butyrate mediates histone crotonylation and alleviated neonatal rats hypoxic-ischemic brain injury through gut-brain axis.\nAbstract: Neonatal hypoxic-ischemic encephalopathy (HIE) refers to nervous system damage caused by perinatal hypoxia, which is the major cause of long-term neuro-developmental disorders in surviving infants. However, the mechanisms still require further investigation. In this study, we found that the butanoate metabolism pathway exhibited significantly decreased and short chain fatty acid (SCFAs)-producing bacteria, especially butyrate-producing bacteria, were significantly decreased in fecal of neonatal hypoxic-ischemic brain damage (HIBD) rats. Surprisingly, Sodium butyrate (SB) treatment could ameliorate pathological damage both in the cerebral cortex and hippocampus and facilitate recovery of SCFAs-producing bacteria related to metabolic pathways in neonatal HIBD rats. Moreover, we found that in samples from SB treatment neonatal HIBD rats cortex with high levels of butyrate acid along with aberrant key crotonyl-CoA-producing enzymes ACADS levels were observed compared HIBD rats. We also demonstrated that a decrease in histone 3-lysine 9-crotonylation (H3K9cr) downregulated expression of the HIE-related neurotrophic genes Bdnf, Gdnf, Cdnf, and Manf in HIBD rats. Furthermore, SB restored H3K9cr binding to HIE-related neurotrophic genes. Collectively, our results indicate that SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression. This may be a novel microbiological approach for preventing and treating HIE.\n\nID: 35652596\nTitle: Fenofibrate Improves Cognitive Impairment Induced by High-Fat High-Fructose Diet: A Possible Role of Irisin and Heat Shock Proteins.\nAbstract: A high-fat, high-fructose diet (HFFD) impairs cognitive functions and increases susceptibility to neurodegenerative disorders. Irisin and heat shock protein 70 (HSP70) are well known for their role in neuroprotection. The possible neuroprotective effects of fenofibrate on HFFD-induced cognitive dysfunction and the involvement of irisin and HSP70 in these effects were investigated in this study. Rats were divided into normal control, HFFD, dimethylsulfoxide+HFFD, and fenofibrate+HFFD groups. At the end of the experiment, fenofibrate treatment restored hippocampus histological characteristics to almost normal and improved HFFD-induced cognitive deficit. It reduced body weight gain and had hypolipidemic effects by significantly lowering total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels while increasing high-density lipoprotein cholesterol levels. It has antioxidant and anti-inflammatory effects as it significantly reduced the hippocampal malondialdehyde, interleukin-6, and tumor necrosis factor-alpha levels, while significantly increasing the reduced glutathione level. It prevented HFFD-induced hypoxia by significantly lowering hippocampal vascular endothelial growth factor and hypoxia-inducible factor-1 alpha levels. It significantly activated the hippocampal peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1\u03b1)/irisin/brain-derived neurotrophic factor pathway. It significantly increased hippocampal HSP70 while decreasing the HSP90 levels. It enhanced synaptic plasticity by significantly upregulating the hippocampal relative GluR1 gene expression. Furthermore, hippocampal irisin levels in the HFFD group were found to be positively correlated with cognitive function, hippocampal HSP70, and relative GluR1 gene expression levels, while negatively correlated with hippocampal HSP90 and HIF1\u03b1 levels. Therefore, fenofibrate may be used as a potential medication to treat HFFD-induced neurodegenerative disorders.\n\nID: 35348035\nTitle: Lithium upregulates growth-associated protein-43 (GAP-43) and postsynaptic density-95 (PSD-95) in cultured neurons exposed to oxygen-glucose deprivation and improves electrophysiological outcomes in rats subjected to transient focal cerebral ischemia following a long-term recovery period.\nAbstract: Lithium has numerous neuroplastic and neuroprotective effects in patients with stroke. Here, we evaluated whether delayed and short-term lithium treatment reduces brain infarction volume and improves electrophysiological and neurobehavioral outcomes following long-term recovery after cerebral ischemia and the possible contributions of lithium-mediated mechanisms of neuroplasticity. Male Sprague Dawley rats were subjected to right middle cerebral artery occlusion for 90\u00a0min, followed by 28\u00a0days of recovery. Lithium chloride (1 mEq/kg) or vehicle was administered via intraperitoneal infusion once per day at 24\u00a0h after reperfusion onset. Neurobehavioral outcomes and somatosensory evoked potentials (SSEPs) were examined before and 28\u00a0days after ischemia-reperfusion. Brain infarction was assessed using Nissl staining. Primary cortical neuron cultures were exposed to oxygen-glucose deprivation (OGD) and treated with 2 or 20\u00a0\u03bcM lithium for 24 or 48\u00a0h; subsequent brain-derived neurotrophic factor (BDNF), growth-associated protein-43 (GAP-43), postsynaptic density-95 (PSD-95), and synaptosomal-associated protein-25 (SNAP-25) levels were analyzed using western blotting. Compared to controls, lithium significantly reduced infarction volume in the ischemic brain and improved electrophysiological and neurobehavioral outcomes at 28\u00a0days post-insult. In cultured cortical neurons, BDNF, GAP-43, and PSD-95 expression were enhanced by 24- and 48-h treatment with lithium after OGD. Lithium upregulates BDNF, GAP-43, and PSD-95, which partly accounts for its improvement of neuroplasticity and provision of long-term neuroprotection in the ischemic brain.Abbreviations: BDNF: brain-derived neurotrophic factor; ECM: extracellular matrix; EDTA: ethylenediaminetetraacetic acid; GAP-43: growth-associated protein-43; GSK-3\u03b2: glycogen synthase kinase-3\u03b2; HBSS: Hank's balanced salt solution; LCBF: local cortical blood perfusion; LDF: laser-Doppler flowmetry; MCAO: middle cerebral artery occlusion; MMP: matrix metalloproteinase; NMDA: N-methyl-D-aspartate; NMDAR: N-methyl-D-aspartate receptor; OCT: optimal cutting temperature compound; OGD: oxygen-glucose deprivation; PSD-95: postsynaptic density-95; SDS: sodium dodecyl sulfate; SNAP-25: synaptosomal-associated protein-25; SSEP: somatosensory evoked potential.\n\nID: 34712383\nTitle: DCA Protects against Oxidation Injury Attributed to Cerebral Ischemia-Reperfusion by Regulating Glycolysis through PDK2-PDH-Nrf2 Axis.\nAbstract: Cerebral ischemic stroke (IS) is still a difficult problem to be solved; energy metabolism failure is one of the main factors causing mitochondrion dysfunction and oxidation stress damage within the pathogenesis of cerebral ischemia, which produces considerable reactive oxygen species (ROS) and opens the blood-brain barrier. Dichloroacetic acid (DCA) can inhibit pyruvate dehydrogenase kinase (PDK). Moreover, DCA has been indicated with the capability of increasing mitochondrial pyruvate uptake and promoting oxidation of glucose in the course of glycolysis, thereby improving the activity of pyruvate dehydrogenase (PDH). As a result, pyruvate flow is promoted into the tricarboxylic acid cycle to expedite ATP production. DCA has a protective effect on IS and brain ischemia/reperfusion (I/R) injury, but the specific mechanism remains unclear. This study adopted a transient middle cerebral artery occlusion (MCAO) mouse model for simulating IS and I/R injury in mice. We investigated the mechanism by which DCA regulates glycolysis and protects the oxidative damage induced by I/R injury through the PDK2-PDH-Nrf2 axis. As indicated from the results of this study, DCA may improve glycolysis, reduce oxidative stress and neuronal death, damage the blood-brain barrier, and promote the recovery of oxidative metabolism through inhibiting PDK2 and activating PDH. Additionally, DCA noticeably elevated the neurological score and reduced the infarct volume, brain water content, and necrotic neurons. Moreover, as suggested from the results, DCA elevated the content of Nrf2 as well as HO-1, i.e., the downstream antioxidant proteins pertaining to Nrf2, while decreasing the damage of BBB and the degradation of tight junction proteins. To simulate the condition of hypoxia and ischemia in vitro, HBMEC cells received exposure to transient oxygen and glucose deprivation (OGD). The DCA treatment is capable of reducing the oxidative stress and blood-brain barrier of HBMEC cells after in vitro hypoxia and reperfusion (H/R). Furthermore, this study evidenced that HBMEC cells could exhibit higher susceptibility to H/R-induced oxidative stress after ML385 application, the specific inhibitor of Nrf2. Besides, the protection mediated by DCA disappeared after ML385 application. To sum up, as revealed from the mentioned results, DCA could exert the neuroprotective effect on oxidative stress and blood-brain barrier after brain I/R injury via PDK2-PDH-Nrf2 pathway activation. Accordingly, the PDK2-PDH-Nrf2 pathway may play a key role and provide a new pharmacology target in cerebral IS and I/R protection by DCA.\n\nID: 34629091\nTitle: Study of montelukast in children with sickle cell disease (SMILES): a study protocol for a randomised controlled trial.\nAbstract: Young children with sickle cell anaemia (SCA) often have slowed processing speed associated with reduced brain white matter integrity, low oxygen saturation, and sleep-disordered breathing (SDB), related in part to enlarged adenoids and tonsils. Common treatments for SDB include adenotonsillectomy and nocturnal continuous positive airway pressure (CPAP), but adenotonsillectomy is an invasive surgical procedure, and CPAP is rarely well-tolerated. Further, there is no current consensus on the ability of these treatments to improve cognitive function. Several double-blind, randomised controlled trials (RCTs) have demonstrated the efficacy of montelukast, a safe, well-tolerated anti-inflammatory agent, as a treatment for airway obstruction and reducing adenoid size for children who do not have SCA. However, we do not yet know whether montelukast reduces adenoid size and improves cognition function in young children with SCA. The Study of Montelukast In Children with Sickle Cell Disease (SMILES) is a 12-week multicentre, double-blind, RCT. SMILES aims to recruit 200 paediatric patients with SCA and SDB aged 3-7.99\u2009years to assess the extent to which montelukast can improve cognitive function (i.e. processing speed) and sleep and reduce adenoidal size and white matter damage compared to placebo. Patients will be randomised to either montelukast or placebo for 12\u2009weeks. The primary objective of the SMILES trial is to assess the effect of montelukast on processing speed in young children with SCA. At baseline and post-treatment, we will administer a cognitive evaluation; caregivers will complete questionnaires (e.g. sleep, pain) and measures of demographics. Laboratory values will be obtained from medical records collected as part of standard care. If a family agrees, patients will undergo brain MRIs for adenoid size and other structural and haemodynamic quantitative measures at baseline and post-treatment, and we will obtain overnight oximetry. Findings from this study will increase our understanding of whether montelukast is an effective treatment for young children with SCA. Using cognitive testing and MRI, the SMILES trial hopes to gain critical knowledge to help develop targeted interventions to improve the outcomes of young children with SCA.

Here, we evaluate the bioactivity of essential oil and the various polarity-based solvent partitioned fractions obtained from Curcuma caesia for anti-amnesia, anxiolytic and antidepressant activities using Elevated plus maze and Morris water maze models. The cold maceration technique using methanol was adopted for extraction from dried powdered rhizomes and essential oil was extracted by hydrodistillation method. Partitioning of the methanolic extract based on solvent polarity by hexane, ethyl acetate, and methanol was continued, followed by column chromatography of the ethyl acetate fraction. Suspensions were prepared for fractions (dissolved in distilled water) and essential oil (dissolved in tween 20) at 200 mg/kg and 400 mg/kg after acute toxicity study and were orally administered to Wistar albino female rats after the orientation of hypoxia by sodium nitrite (50 mg/kg) and amnesia by scopolamine (1 mg/kg). Behavioural observations, biochemical and histopathological examinations were carried out for all the treated groups. Diazepam (12 mg/kg) and galantamine (3 mg/kg) were used as standard drugs for this study against hypoxia and amnesia. Data acquired from behavioural, biochemical (acetylcholinesterase, myeloperoxidase, superoxide dismutase, reduced glutathione, catalase) and histopathological studies have illustrated that fraction II acquires highly significant memory-enhancing, anxiolytic and antidepressant effects. Rest fractions (I and III) and essential oil showed moderate efficacy. In prospects, identification of active molecules from the most active fraction (fraction II) and further studies on a molecular basis would substantiate its specific mechanism of neuroprotective action.\n\nID: 33788269\nTitle: HDAC inhibition prevents hypobaric hypoxia-induced spatial memory impairment through\u00a0P\u03993K/GSK3\u03b2/CREB pathway.\nAbstract: Hypobaric hypoxia at higher altitudes usually impairs cognitive function. Previous studies suggested that epigenetic modifications are the culprits for this condition. Here, we set out to determine how hypobaric hypoxia mediates epigenetic modifications and how this condition worsens neurodegeneration and memory loss in rats. In the current study, different duration of hypobaric hypoxia exposure showed a discrete pattern of\u00a0histone acetyltransferases\u00a0and histone deacetylases (HDACs)\u00a0gene\u00a0expression in the hippocampus when compared with control rat brains. The level of acetylation sites in histone H2A, H3\u00a0and H4 was significantly decreased under hypobaric hypoxia exposure compared to the control rat's hippocampus. Additionally, inhibiting the HDAC family with sodium butyrate administration (1.2\u2009g/kg body weight) attenuated neurodegeneration and memory loss in hypobaric hypoxia-exposed rats. Moreover, histone acetylation increased at the promoter regions of brain-derived neurotrophic factor\u00a0(BDNF);\u00a0thereby its protein expression was enhanced significantly in hypobaric hypoxia exposed rats treated with HDAC inhibitor compared with hypoxic rats. Thus, BDNF expression upregulated cAMP-response element binding protein (CREB) phosphorylation by stimulation of PI3K/GSK3\u03b2/CREB axis, which counteracts hypobaric hypoxia-induced spatial memory impairment. In conclusion, these results suggested that sodium butyrate is a novel therapeutic agent for the treatment of spatial memory loss associated with hypobaric hypoxia, and also further studies are warranted to explore specific HDAC inhibitors in this condition.\n\nID: 33285471\nTitle: The potential LXR\u03b2 agonist stigmasterol protects against hypoxia/reoxygenation injury by modulating mitophagy in primary hippocampal neurons.\nAbstract: Neuronal excitotoxicity induces a plethora of downstream signaling pathways, resulting in the calcium overload-induced excitotoxic cell death, a well-known phenomenon in cerebrovascular and neurodegenerative disorders. The naturally occurring phytosterol, stigmasterol (ST) is known for its potential role in cholesterol homeostasis and neuronal development. However, the ability of ST to protect against the induced excitotoxicity in hippocampal neurons has not been investigated yet. The present study aimed to investigate whether ST could protect against hypoxia/reoxygenation (H/R)-induced excitotoxicity in hippocampal neurons. After H/R, neurons were initially subjected to trypan blue exclusion assay for the assessment of cell viability. Live staining using fluorescence dyes namely JC-1 (5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide), DCFDA (2',7'-dichlorofluorescein diacetate) and FM1-43 (N-(3-triethylammoniumpropyl)-4-(4-(dibutylamino)styryl) were used to measure MMP, ROS and synaptic vesicle pool size. Immunostaining was performed to analyze the expression levels of vesicular glutamate transporter 1 (VGLUT1), N-methyl-D-acetate receptor subunit 2B (GluN2B), LC3BII, p62, and PTEN induced protein kinase 1 (PINK1) in neuron after H/R. Western blotting was carried out to measure the protein expression of GluN2B. The molecular dynamics simulation was employed to elucidate the LXR\u03b2 agonistic conformation of ST. Pre-incubation of neuronal cultures with ST (20 \u03bcM) protected against excitotoxicity, and attenuated reactive oxygen species (ROS) generation, double-stranded DNA break, and mitochondrial membrane potential (MMP) loss. ST treatment also resulted in the downregulation of the expressions of VGLUT1 and GluN2B and the reduction of the size of recyclable synaptic vesicle (SV) pool. Like LXR\u03b2 agonist GW3695, ST suppressed the expression of GluN2B. Furthermore, ST induced mitophagy through upregulating the expressions of LC3BII, p62, and PINK1. The molecular simulation study showed that ST interacted with the ligand binding domain of liver X receptor \u03b2 (LXR\u03b2), a known binding receptor of ST, through multiple hydrogen bonding. Collectively, these findings revealed that ST exhibited a promising neuroprotective effect by regulating both pre- and post-synaptic events following H/R, particularly, attenuation of GluN2B-mediated excitotoxicity and oxidative stress, and induction of mitophagy, and suggested that ST might be a therapeutic promise against ischemic stroke and its associated neurological disorders.\n\nID: 32994545\nTitle: Waixenicin A, a marine-derived TRPM7 inhibitor: a promising CNS drug lead.\nAbstract: Ion channels are the third largest class of targets for therapeutic drugs. The pharmacology of ion channels is an important research area for identifying new treatment options for human diseases. The past decade or so has seen increasing interest in an ion channel protein belonging to the transient receptor potential (TRP) family, namely the melastatin subfamily member 7 (TRPM7), as an emerging drug target. TRPM7 is a bifunctional protein with a\u00a0magnesium and calcium-conducting divalent ion channel fused with an active kinase domain. TRPM7 is ubiquitously expressed in human tissues, including the brain, and regulates various cell biology processes such as magnesium and calcium homeostasis, cell growth and proliferation, and embryonic development. TRPM7 provides a link between cellular metabolic status and intracellular calcium homeostasis in neurons due to TRPM7's unique sensitivity to fluctuating intracellular Mg\u00b7ATP levels. Thus, the protein plays a key role in ischemic and hypoxic neuronal cell death and brain injury, and is one of the key nonglutamate mechanisms in cerebral ischemia and stroke. Currently, the most potent and specific TRPM7 inhibitor is waixenicin A, a xenicane diterpenoid from the Hawaiian soft coral Sarcothelia edmondsoni. Using waixenicin A as a pharmacological tool, we demonstrated that TRPM7 is involved in promoting neurite outgrowth in vitro. Most recently, we found that waixenicin A reduced hypoxic-ischemic brain injury and preserved long-term behavioral outcomes in mouse neonates. We here suggest that TRPM7 is an emerging drug target for CNS diseases and disorders, and waixenicin A is a viable drug lead for these disorders.\n\nID: 32887181\nTitle: Methyl jasmonate delays the latency to anoxic convulsions by normalizing the brain levels of oxidative stress biomarkers and serum corticosterone contents in mice with repeated anoxic stress.\nAbstract: Repeated exposure to anoxic stress damages the brain through cortisol-mediated increases in oxidative stress and cellular-antioxidants depletion. Thus, compounds with antioxidant property might confer protection against anoxic stress-induced brain injuries. In this study, we further examined the protective effect of methyl jasmonate (MJ), a potent anti-stress agent against anoxic stress-induced convulsions in mice. Thirty-six male Swiss mice randomized into six groups (n=6) were given MJ (25, 50 and 100\u00a0mg/kg, i.p.) or vehicle (10\u00a0mL/kg, i.p.) 30\u00a0min before 15\u00a0min daily exposure to anoxic stress for 7\u00a0days. The latency(s) to anoxic convulsion was recorded on day 7. The blood glucose and serum corticosterone levels were measured afterwards. The brains were also processed for the determination of malondialdehyde, nitrite, and glutathione levels. Methyl jasmonate (MJ) delayed the latency to anoxic convulsion and reduced the blood glucose and serum corticosterone levels. The increased malondialdehyde and nitrite contents accompanied by decreased glutathione concentrations in mice with anoxic stress were significantly attenuated by MJ. These findings further showed that MJ possesses anti-stress property via mechanisms relating to the reduction of serum contents of corticosterone and normalization of brain biomarker levels of oxidative stress in mice with anoxic stress.\n\nID: 32622201\nTitle: Casticin suppresses monoiodoacetic acid-induced knee osteoarthritis through inhibiting HIF-1\u03b1/NLRP3 inflammasome signaling.\nAbstract: Knee osteoarthritis (KOA) is a disabling chronic inflammatory disease that is closely associated with synovium tissue hypoxia and synovial fibrosis. Casticin, a compound purified from the Chinese herb Viticis Fructus, has been proved effective in preventing inflammation and fibrosis in previous studies. However, the effect of casticin on synovial fibrosis in KOA is not clear. In present study, we aimed to investigate how did casticin affect synovial fibrosis on monoiodoacetic acid (MIA)-induced KOA in rats. The MIA-induced knee osteoarthritis model and lipopolysaccharide (LPS) stimulated primary synovial fibroblasts inflammation model were established. Pathological and morphological changes in synovial tissue were observed by H&E and sirius red staining. The hypoxia of synovium was detected by pimonidazole staining and immunohistochemistry of hypoxia-inducible factors 1\u03b1 (HIF-1\u03b1). The levels of nucleotide oligomerization domain-like receptor protein 3 (NLRP3) inflammasome components, fibrogenic markers (TGF-\u03b2, COL1A1 and TIMP1) and inflammatory cytokines were examined by western blotting, qRT-PCR or ELISA in both KOA rat models and primary synovial fibroblasts. Our data suggested that casticin improved hypoxia and inflammation in synovium tissue, as well the synovial fibrosis in rats. Besides, casticin inhibited the activation of NLRP3 inflammasome in MIA-induced KOA rats and synovial fibroblasts. In conclusion, our findings demonstrated that casticin alleviated MIA-induced KOA by inhibiting of HIF-1\u03b1/NLRP3 inflammasome activation. Therefore, casticin could be a potential treatment strategy for KOA.\n\nID: 32471267\nTitle: Impact of a Histone Deacetylase Inhibitor-Trichostatin A on Neurogenesis after Hypoxia-Ischemia in Immature Rats.\nAbstract: Hypoxia-ischemia (HI) in the neonatal brain frequently results in neurologic impairments, including cognitive disability. Unfortunately, there are currently no known treatment options to minimize ischemia-induced neural damage. We previously showed the neuroprotective/neurogenic potential of a histone deacetylase inhibitor (HDACi), sodium butyrate (SB), in a neonatal HI rat pup model. The aim of the present study was to examine the capacity of another HDACi-Trichostatin A (TSA)-to stimulate neurogenesis in the subgranular zone of the hippocampus. We also assessed some of the cellular/molecular processes that could be involved in the action of TSA, including the expression of neurotrophic factors (glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), and brain-derived neurotrophic factor (BDNF)) as well as the TrkB receptor and its downstream signalling substrate- cAMP response element-binding protein (CREB). Seven-day-old rat pups were subjected to unilateral carotid artery ligation followed by hypoxia for 1 h. TSA was administered directly after the insult (0.2 mg/kg body weight). The study demonstrated that treatment with TSA restored the reduced by hypoxia-ischemia number of immature neurons (neuroblasts, BrdU/DCX-positive) as well as the number of oligodendrocyte progenitors (BrdU/NG2+) in the dentate gyrus of the ipsilateral damaged hemisphere. However, new generated cells did not develop the more mature phenotypes. Moreover, the administration of TSA stimulated the expression of BDNF and increased the activation of the TrkB receptor. These results suggest that BDNF-TrkB signalling pathways may contribute to the effects of TSA after neonatal hypoxic-ischemic injury.\n\nID: 32430797\nTitle: TRPM7 Mediates Neuronal Cell Death Upstream of Calcium/Calmodulin-Dependent Protein Kinase II and Calcineurin Mechanism in Neonatal Hypoxic-Ischemic Brain Injury.\nAbstract: Transient receptor potential melastatin 7 (TRPM7), a calcium-permeable, ubiquitously expressed ion channel, is critical for axonal development, and mediates hypoxic and ischemic neuronal cell death in vitro and in vivo. However, the downstream mechanisms underlying the TRPM7-mediated processes in physiology and pathophysiology remain unclear. In this study, we employed a mouse model of hypoxic-ischemic brain cell death which mimics the pathophysiology of hypoxic-ischemic encephalopathy (HIE). HIE is a major public health issue and an important cause of neonatal deaths worldwide; however, the available treatments for HIE remain limited. Its survivors face life-long neurological challenges including mental retardation, cerebral palsy, epilepsy and seizure disorders, motor impairments, and visual and auditory impairments. Through a proteomic analysis, we identified calcium/calmodulin-dependent protein kinase II (CaMKII) and phosphatase calcineurin as potential mediators of cell death downstream from TRPM7 activation. Further analysis revealed that TRPM7 mediates cell death through CaMKII, calmodulin, calcineurin, p38, and cofilin cascade. In vivo, we found a significant reduction of brain injury and improvement of short- and long-term functional outcomes after HI after administration of specific TRPM7 blocker waixenicin A. Our data demonstrate a molecular mechanism of TRPM7-mediated cell death and identifies TRPM7 as a promising therapeutic and drug development target for HIE.\n\nID: 32389853\nTitle: Network pharmacology-based strategy to investigate pharmacological mechanisms of Tinospora sinensis for treatment of Alzheimer's disease.\nAbstract: Tinospora sinensis (Lour.) Merr. belongs to the family Menispermaceae. It is called LeZhe and is widely used as a kind of folk medicine especially in the Tibetan Plateau of China. T. sinensis has the functions of clearing away heat and detoxification, dispelling wind and dredging collaterals, calming and soothing the nerves. T. sinensis is an effective medicine for the prevention and treatment of aging diseases such as Alzheimer's disease (AD) in the Tibetan Plateau of China, whereas its material basis and underlying mechanisms are not clear. The aim of this study was to investigate the material basis and potential mechanisms of T. sinensis in the treatment of AD by using network pharmacology and molecular docking. In this study, targets were collected from DrugBank database, Therapeutic Target Database (TTD) and literatures reports for the treatment of AD. Compounds were searched by literatures and systematic separation from T. sinensis. The molecular docking experiment was carried out by using Autodock Vina software to screen the bioactive compounds in T. sinensis and target proteins for AD. Then, the \"compound-target network\" was constructed by Cytoscape software. The drug-like properties of the active compounds were analyzed by pKCSM performs, and the protein-protein interaction (PPI) network was constructed by Search Tool for the Retrieval of Interacting Genes/Proteins (STRING). The Kyoto Encyclopedia of Genes and Genomes (KEGG) target pathway enrichment analysis was carried out by Database for Annotation, Visualization and Integrated Discovery (DAVID). Furthermore, the protective effect of neurons of two active compounds were verified with the injury cell model of PC12 and primary hippocampus neurons induced by A\u03b225-35. Finally, the key proteins of related pathways were quantitatively analyzed with Western blot method. In total, 105 compounds and 38 targets have been screened. The main active compounds contained berberine, which belongs to alkaloids, Aurantiamide acetate, N-P-coumaroyltyramine, which belongs to amides, Trans-syringin and 3-demethyl-phillyrin, which belongs to phenylpropanoids. The targets covered inflammation-related proteins, including Protein kinase B (AKT), Phosphoinositide 3-kinase (PI3K), Tyrosine-protein kinase JAK1 (JAK1), mammalian target of rapamycin (mTOR), tumor necrosis factor alpha (TNF-\u03b1), Neuronal NOS (NOS1), and cholinergic function-related proteins, including \u03b14-Nicotinic acetylcholine receptor (\u03b14 nAChR), Muscarinic acetylcholine receptor M1 (Muscarnic M1). Inflammation and cholinergic dysfunction were the center of the network and occupy a dominant position. And the results of enrichment analysis shown the pathways mainly contained phosphoinositide-3-kinase/Akt (PI3K/Akt) signal pathway, neurotrophic factors (NTFs) signal pathway, Hypoxia-inducible factor 1 (HIF-1) signal pathway, mechanistic Target of Rapamycin (mTOR) signal pathway, Tumor necrosis factor (TNF) signal pathway, insulin resistance (IR). The results of in vitro assays showed that the tested compounds could significantly improve the survival rate and inhibit the apoptosis of PC12\u00a0cells and primary hippocampal neurons injured by A\u03b225-35. Western blot results showed that T. sinensis had a significant effect on the expression of protein PI3K and Akt. Our results revealed that T. sinensis could prevent and treat AD through a multi-compound-multi-target-multi-pathway regulatory network. Our work also expected to provide new ideas and theoretical bases for searching for the active compounds in T. sinensis and potential mechanism in the prevention and treatment of AD by the network pharmacology and molecular docking. The results of in vitro assay and in vivo assay supported the results of molecular docking.\n\nID: 32382851\nTitle: Evans Blue Might Produce Pathologically Activated Neuroprotective Effects via the Inhibition of the P2X4R/p38 Signaling Pathway.\nAbstract: The main pathological features of ischemic stroke include neuronal damage and blood-brain barrier (BBB) dysfunction. Previous studies have shown that Evans Blue, a dye used to probe BBB integrity, could enter the brain only during the pathological status of ischemic stroke, indicating the potential pathologically activated therapeutic use of this chemical to treat ischemic stroke. In this study, we have reported that Evans Blue could produce in vitro neuroprotective effects against iodoacetic acid (IAA)-induced hypoxia neuronal death in HT22 cells. We further found that P2X\u00a0purinoreceptor 4 (P2X4R), a subtype of ATP-gated\u00a0cation\u00a0channel, was expressed in HT22 cells. Evans Blue could prevent IAA-induced increase of P2X4R mRNA and protein expression. Interestingly, shRNA of P2X4R could protect against IAA-induced activation of p38, and SB203580, a specific inhibitor of p38, could reverse IAA-induced neurotoxicity, indicating that p38 is a downstream signaling molecule of P2X4R. Molecular docking analysis further demonstrated the possible interaction between Evans Blue and the ATP binding site of P2X4R. Most importantly, pre-treatment of Evans Blue could largely reduce neurological and behavioral abnormity, and decrease brain infarct volume in middle cerebral artery occlusion/reperfusion (MCAO) rats. All these results strongly suggested that Evans Blue could exert neuroprotective effects via inhibiting the P2X4R/p38 pathway, possibly by acting on the ATP binding site of P2X4R, indicating that Evans Blue might be further developed as a pathologically activated therapeutic drug against ischemic stroke.\n\nID: 32182924\nTitle: Gelidium amansii Attenuates Hypoxia/Reoxygenation-Induced Oxidative Injury in Primary Hippocampal Neurons through Suppressing GluN2B Expression.\nAbstract: Oxidative stress is known to be critically implicated in the pathophysiology of several neurological disorders, including Alzheimer's disease and ischemic stroke. The remarkable neurotrophic activity of Gelidium amansii, which has been reported consistently in a series of our previous studies, inspired us to investigate whether this popular agarophyte could protect against hypoxia/reoxygenation (H/R)-induced oxidative injury in hippocampal neurons. The primary culture of hippocampal neurons challenged with H/R suffered from a significant loss of cell survival, accompanied by apoptosis and necrosis, DNA damage, generation of reactive oxygen species (ROS), and dissipation of mitochondrial membrane potential (\u0394\u03a8m), which were successfully attenuated when the neuronal cultures were preconditioned with ethanolic extract of G. amansii (GAE). GAE also attenuated an H/R-mediated increase of BAX and caspase 3 expressions while promoting Bcl-2 expression. Moreover, the expression of N-methyl-d-acetate receptor subunit 2B (GluN2B), an extrasynaptic glutamate receptor, was significantly repressed, while synaptic GluN2A expression was preserved in GAE-treated neurons as compared to those without GAE intervention. Together, this study demonstrates that GAE attenuated H/R-induced oxidative injury in hippocampal neurons through, at least in part, a potential neuroprotective mechanism that involves inhibition of GluN2B-mediated excitotoxicity and suppression of ROS production, and suggests that this edible seaweed could be a potential source of bioactive metabolites with therapeutic significance against oxidative stress-related neurodegeneration, including ischemic stroke and neurodegenerative diseases.\n\nID: 32048876\nTitle: Intermittent Hypoxia Augments Pulmonary Vasoconstrictor Reactivity through PKC\u03b2/Mitochondrial Oxidant Signaling.\nAbstract: Pulmonary vasoconstriction resulting from intermittent hypoxia (IH) contributes to pulmonary hypertension (pHTN) in patients with sleep apnea (SA), although the mechanisms involved remain poorly understood. Based on prior studies in patients with SA and animal models of SA, the objective of this study was to evaluate the role of PKC\u03b2 and mitochondrial reactive oxygen species (mitoROS) in mediating enhanced pulmonary vasoconstrictor reactivity after IH. We hypothesized that PKC\u03b2 mediates vasoconstriction through interaction with the scaffolding protein PICK1 (protein interacting with C kinase 1), activation of mitochondrial ATP-sensitive potassium channels (mitoKATP), and stimulated production of mitoROS. We further hypothesized that this signaling axis mediates enhanced vasoconstriction and pHTN after IH. Rats were exposed to IH or sham conditions (7 h/d, 4 wk). Chronic oral administration of the antioxidant Tempol or the PKC\u03b2 inhibitor LY-333531 abolished IH-induced increases in right ventricular systolic pressure and right ventricular hypertrophy. Furthermore, scavengers of O2- or mitoROS prevented enhanced PKC\u03b2-dependent vasoconstrictor reactivity to endothelin-1 in pulmonary arteries from IH rats. In addition, this PKC\u03b2/mitoROS signaling pathway could be stimulated by the PKC activator PMA in pulmonary arteries from control rats, and in both rat and human pulmonary arterial smooth muscle cells. These responses to PMA were attenuated by inhibition of mitoKATP or PICK1. Subcellular fractionation and proximity ligation assays further demonstrated that PKC\u03b2 acutely translocates to mitochondria upon stimulation and associates with PICK1. We conclude that a PKC\u03b2/mitoROS signaling axis contributes to enhanced vasoconstriction and pHTN after IH. Furthermore, PKC\u03b2 mediates pulmonary vasoconstriction through interaction with PICK1, activation of mitoKATP, and subsequent mitoROS generation.\n\nID: 31922892\nTitle: PKC\u03b2 and reactive oxygen species mediate enhanced pulmonary vasoconstrictor reactivity following chronic hypoxia in neonatal rats.\nAbstract: Reactive oxygen species (ROS), mitochondrial dysfunction, and excessive vasoconstriction are important contributors to chronic hypoxia (CH)-induced neonatal pulmonary hypertension. On the basis of evidence that PKC\u03b2 and mitochondrial oxidative stress are involved in several cardiovascular and metabolic disorders, we hypothesized that PKC\u03b2 and mitochondrial ROS (mitoROS) signaling contribute to enhanced pulmonary vasoconstriction in neonatal rats exposed to CH. To test this hypothesis, we examined effects of the PKC\u03b2 inhibitor LY-333,531, the ROS scavenger 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine (TEMPOL), and the mitochondrial antioxidants mitoquinone mesylate (MitoQ) and (2-(2,2,6,6-tetramethylpiperidin-1-oxyl-4-ylamino)-2-oxoethyl)triphenylphosphonium chloride (MitoTEMPO) on vasoconstrictor responses in saline-perfused lungs (in situ) or pressurized pulmonary arteries from 2-wk-old control and CH (12-day exposure, 0.5 atm) rats. Lungs from CH rats exhibited greater basal tone and vasoconstrictor sensitivity to 9,11-dideoxy-9\u03b1,11\u03b1-methanoepoxy prostaglandin F2\u03b1 (U-46619). LY-333,531 and TEMPOL attenuated these effects of CH, while having no effect in lungs from control animals. Basal tone was similarly elevated in isolated pulmonary arteries from neonatal CH rats compared with control rats, which was inhibited by both LY-333,531 and mitochondria-targeted antioxidants. Additional experiments assessing mitoROS generation with the mitochondria-targeted ROS indicator MitoSOX revealed that a PKC\u03b2-mitochondrial oxidant signaling pathway can be pharmacologically stimulated by the PKC activator phorbol 12-myristate 13-acetate in primary cultures of pulmonary artery smooth muscle cells (PASMCs) from control neonates. Finally, we found that neonatal CH increased mitochondrially localized PKC\u03b2 in pulmonary arteries as assessed by Western blotting of subcellular fractions. We conclude that PKC\u03b2 activation leads to mitoROS production in PASMCs from neonatal rats. Furthermore, this signaling axis may account for enhanced pulmonary vasoconstrictor sensitivity following CH exposure.NEW & NOTEWORTHY This research demonstrates a novel contribution of PKC\u03b2 and mitochondrial reactive oxygen species signaling to increased pulmonary vasoconstrictor reactivity in chronically hypoxic neonates. The results provide a potential mechanism by which chronic hypoxia increases both basal and agonist-induced pulmonary arterial smooth muscle tone, which may contribute to neonatal pulmonary hypertension.\n\nID: 31550185\nTitle: Trans-Himalayan Phytococktail Confers Protection Against Hypobaric Hypoxia-Induced Hippocampal Neurodegeneration and Memory Impairment in Male Sprague Dawley Rats.\nAbstract: Background: Exposure to hypobaric hypoxia (HH) has been reported to cause neurodegeneration and memory impairment. Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and Amchi system of medicine. These are rich sources of diverse bioactive metabolites having prophylactic and therapeutic uses against a wide array of neurodegenerative diseases. The objective of this study was to elucidate the prophylactic and neuroprotective efficacy of formulated phytococktail (PC) against simulated HH-induced neurodegeneration in male Sprague Dawley (SD) rats. Materials and Methods: A PC containing H. rhamnoides fruit pulp, P. armeniaca fruit pulp, and R. imbricata dry root extract (100:50:1) was formulated. The neuroprotective efficacy of PC was evaluated in male SD rats following exposure to 7 day HH at simulated altitude (25,000 ft, 282\u2009mm Hg). Rats were divided into four groups viz., normoxia group (NOR), normoxic group treated with PC (NORPC), 7 day hypoxic group treated with vehicle (7DH), and 7 day hypoxic group treated with PC (7DHPC). Memory impairment and neuromorphological alterations were measured. Targeted protein expression was analyzed by immunoblotting study. Results: PC supplementation significantly reduced the oxidative stress markers during exposure to HH. Spatial memory impairment by HH was significantly ameliorated by PC. HH-induced augmented pyknosis, decreased dendritic arborization, and increased Hoechst-positive neurons in hippocampal CA3 region were significantly ameliorated by PC. Immunoblotting study showed upregulation of BDNF and TrkB expression by PC. PC also prevented the hippocampal neurodegeneration by activating the PI3K/AKT signaling pathway, which leads to GSK-3\u03b2 inactivation by its phosphorylation and alleviation of hippocampal Caspase3 expression leading to inhibition of apoptotic neuronal cell death. Conclusion: The present study advocates the potential role of PC as an effective neuroprotective supplement in preventing HH-induced neurodegeneration. Activation of the PI3K/Akt pathway through BDNF/TrkB interaction following PC supplementation after exposure to HH inhibits hippocampal neuronal apoptosis and memory impairment.\n\nID: 31146971\nTitle: Mononuclear phagocytes orchestrate prolyl hydroxylase inhibition-mediated renoprotection in chronic tubulointerstitial nephritis.\nAbstract: Prolyl hydroxylase domain enzyme inhibitors (PHDIs) stabilize hypoxia-inducible factors (HIFs), and are protective in models of acute ischemic and inflammatory kidney disease. Whether PHDIs also confer protection in chronic inflammatory kidney disease models remains unknown. Here we investigated long-term effects of PHDI treatment in adenine-induced nephropathy as a model for chronic tubulointerstitial nephritis. After three weeks, renal dysfunction and tubulointerstitial damage, including proximal and distal tubular injury, tubular dilation and renal crystal deposition were significantly attenuated in PHDI-treated (the isoquinoline derivative ICA and Roxadustat) compared to vehicle-treated mice with adenine-induced nephropathy. Crystal-induced renal fibrosis was only partially diminished by treatment with ICA. Renoprotective effects of ICA treatment could not be attributed to changes in adenine metabolism or urinary excretion of the metabolite 2,8-dihydroxyadenine. ICA treatment reduced inflammatory infiltrates of F4/80+ mononuclear phagocytes in the kidneys and supported a regulatory, anti-inflammatory immune response. Furthermore, interstitial deposition of complement C1q was decreased in ICA-treated mice fed an adenine-enriched diet. Tubular cell-specific HIF-1\u03b1 and myeloid cell-specific HIF-1\u03b1 and HIF-2\u03b1 expression were not required for the renoprotective effects of ICA. In contrast, depletion of mononuclear phagocytes with clodronate largely abolished the nephroprotective effects of PHD inhibition. Thus, our findings indicate novel and potent systemic anti-inflammatory properties of PHDIs that confer preservation of kidney function and structure in chronic tubulointerstitial inflammation and might counteract kidney disease progression.\n\nID: 42354990\nTitle: The Gut-Brain-Muscle Axis: Microbial Regulation of Neuromuscular Aging and Cognitive Frailty.\nAbstract: Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, has emerged as a major challenge in aging populations and is closely linked to sarcopenia, neurodegeneration, and chronic inflammation. Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity.\n\nID: 41459064\nTitle: Potential effects of cinnamon on cancer prevention and progression.\nAbstract: Cinnamon has been used medicinally for centuries, but recently in vitro research has suggested it may have a role in cancer prevention and potentially treatment. The search for alternative and subjunctive therapies is essential due to the public demand and the increasing cost of healthcare. Here we review the biologically active components of cinnamon and discuss the methods of potential cinnamon activity against cancer, including: transcription factor regulation and kinase activity. Nuclear Factor kappa B (NF\u03baB) is a stress sensitive transcription factor that regulates transcription of genes involved in tumor progression and is inhibited by cinnamon components. Another way that cinnamon inhibits tumor growth is by suppression of transcription factor activator protein 1 (AP1) which interacts with genes responsible for apoptosis, metastasis and inflammation. Hypoxia-inducible transcription factor 1 (HIF1) and vascular endothelial growth factor (VEGF) are involved in angiogenesis, especially in the tumor microenvironment. The HIF1-VEGF pathway is a target of cinnamaldehyde, a compound found in cinnamon. Nuclear factor erythroid related factor 2 (Nrf2) is also examined and has been indicated to affect cancer progression and potentially provide preventative measures; various cinnamon derivatives target Nrf2. A cinnamaldehyde derivative has been implicated in a reduction of the mitogen-activated protein kinases (MAPKs), which are a group of kinases that regulate proliferation. Additionally, cinnamon components have been tied to cancer prevention by positively affecting the gut microbiome and inhibiting inflammation. The review concludes with a discussion of the future research needed, including the need for clinical studies and potential risk associated with cinnamon intake.\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=======================================================\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.

Sacc.Chaidam on gut microbiota in Tibetan Plateau population based on in vitro model.\nAbstract: The intercellular polysaccharides derived from Agaricus bitorquis (Qu\u00e9l.) Sacc. Chaidam (ABIPs) are macromolecules exhibiting significant biological activity and outstanding anti-hypoxia properties. However, the digestive traits of ABIPs within the intestinal microbiota and their adaptive mechanisms to hypoxia in high-altitude populations remain poorly understood. The objective of this study was to investigate the anti-hypoxia mechanism of ABIPs at the small-molecule level through the utilization of the in vitro fermentation model of intestinal flora and the cell hypoxia models. The results indicated that under conditions of hypoxic stress, the total amount of monosaccharides and uronic acids (MUAs) metabolized by ABIPs in the plateau group was comparatively high, predominantly mannose. Furthermore, the level of short-chain fatty acids (SCFAs) produced through their metabolism was also significantly higher than that of the plain group, with acetic-acid, propionic-acid, and butyric-acid constituting a relatively large proportion. Additionally, in the plateau group, the metabolism of ABIPs increased the abundance of Prevotella and Alloprevotella, while the abundance of Collinsella decreased notably. In contrast, the metabolites produced by ABIPs in the plateau group (mainly SCFAs) had a more pronounced inhibitory effect on the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) signaling pathway than in the plain group. Overall, ABIPs may enable cells to develop hypoxia tolerance by enhancing hypoxia-consuming metabolic levels, rebalancing the gut microbiota, and stabilizing the HIF-1\u03b1 signaling pathway, thereby protecting the body from hypoxia damage.\n --- END ACTUAL ABSTRACT FOR 41418957 ---\n\n- ERROR: You cited ID: 42458926 for the quote: \"The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovirion, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculaceae, and Lactobacillus.\"\n FACT: Strict Misquote Detected!

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n --- END ACTUAL ABSTRACT FOR 42458926 ---\n\n- ERROR: You cited ID: 33788269 for the quote: \"Sodium butyrate is a novel therapeutic agent for the treatment of spatial memory loss associated with hypobaric hypoxia, and also further studies are warranted to explore specific HDAC inhibitors in this condition.\"\n FACT: Strict Misquote Detected!

Previous studies suggested that epigenetic modifications are the culprits for this condition. Here, we set out to determine how hypobaric hypoxia mediates epigenetic modifications and how this condition worsens neurodegeneration and memory loss in rats. In the current study, different duration of hypobaric hypoxia exposure showed a discrete pattern of\u00a0histone acetyltransferases\u00a0and histone deacetylases (HDACs)\u00a0gene\u00a0expression in the hippocampus when compared with control rat brains. The level of acetylation sites in histone H2A, H3\u00a0and H4 was significantly decreased under hypobaric hypoxia exposure compared to the control rat's hippocampus. Additionally, inhibiting the HDAC family with sodium butyrate administration (1.2\u2009g/kg body weight) attenuated neurodegeneration and memory loss in hypobaric hypoxia-exposed rats. Moreover, histone acetylation increased at the promoter regions of brain-derived neurotrophic factor\u00a0(BDNF);\u00a0thereby its protein expression was enhanced significantly in hypobaric hypoxia exposed rats treated with HDAC inhibitor compared with hypoxic rats. Thus, BDNF expression upregulated cAMP-response element binding protein (CREB) phosphorylation by stimulation of PI3K/GSK3\u03b2/CREB axis, which counteracts hypobaric hypoxia-induced spatial memory impairment. In conclusion, these results suggested that sodium butyrate is a novel therapeutic agent for the treatment of spatial memory loss associated with hypobaric hypoxia, and also further studies are warranted to explore specific HDAC inhibitors in this condition.\n --- END ACTUAL ABSTRACT FOR 33788269 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction.\" (Source: 42263472)\n- \"SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum.

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]\nMicrobiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\n\nThe claim is supported by the literature. Multiple studies confirm that microbiota-derived acetate (often enhanced by probiotics or specific dietary interventions) mitigates neuroinflammation and cognitive impairment associated with hypoxic conditions, with evidence linking these effects to the restoration or upregulation of brain-derived neurotrophic factor (BDNF).\n\n### [ABSTRACT & REWRITTEN CLAIM]\nHypoxia-induced neurodegeneration and inflammation are mediated by gut-brain axis dysbiosis and the depletion of short-chain fatty acids (SCFAs), primarily acetate. Supplementation with SCFA-producing bacteria or oral acetate restores systemic and central acetate levels, which in turn suppresses inflammatory cytokines (such as IL-1\u03b2 and TNF-\u03b1) and promotes BDNF expression, thereby conferring neuroprotection against cognitive deficits and neuronal injury.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis serves as a critical regulatory system for neuroprotection, particularly under conditions of hypobaric hypoxia and other stressors. Research indicates that hypoxia triggers gut dysbiosis, characterized by a significant reduction in SCFA-producing bacteria. \"SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p.\" Acetate acts as a metabolic modulator that bridges peripheral gut health and central neuroprotection. For instance, \"B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction.\"\n\nFurthermore, acetate\u2019s protective mechanism frequently intersects with the neurotrophic pathway. Studies have shown that therapeutic agents which increase acetate production concurrently elevate BDNF. \"WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress.\" This demonstrates that the restoration of microbial-derived acetate provides a metabolic substrate that enables the brain to mount a robust protective response against hypoxia-induced cellular degeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate's role in the gut-brain axis is not merely as a metabolic byproduct but as a signaling molecule that specifically modulates the expression of neurotrophic factors like BDNF.\n* \"Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment.\"\n* \"Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators.\"\n* The effects of acetate are often mediated through the suppression of the NLRP3 inflammasome, a key node in the neuroinflammatory cascade.\n* \"DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation.\"\n* \"Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces.\"\n* \"In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM).\"\n* \"SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies."

Increasing evidence implicates neuroinflammation, oxidative stress, and dysregulation of neurotrophic and neurotransmitter systems as central mechanisms driving these conditions. Flavonoids, a structurally diverse class of plant-derived polyphenolic compounds abundantly found in fruits, vegetables, tea, and other dietary sources, have emerged as promising modulators of these pathophysiological pathways. This narrative review synthesizes current preclinical and clinical evidence on the role of flavonoids and related natural compounds in modulating neuroinflammation and affective disorders. We describe the major flavonoid subclasses-flavones, flavonols, isoflavones, anthocyanins, flavanones, and flavan-3-ols-and analyze their mechanisms of action, including inhibition of the NF-\u03baB/NLRP3 axis, reduction in pro-inflammatory cytokines, attenuation of oxidative stress via Nrf2 pathway activation, modulation of monoaminergic and GABAergic neurotransmission, promotion of Brain-Derived Neurotrophic Factor (BDNF)-mediated neuroplasticity, and regulation of the microbiota-gut-brain axis. Preclinical studies consistently demonstrate anxiolytic and antidepressant effects for compounds such as quercetin, luteolin, apigenin, and chrysin; however, clinical evidence remains limited and methodologically heterogeneous. Future research should prioritize bioavailability-enhanced formulations, standardized clinical trials, and biomarker-guided stratification to fully establish the therapeutic potential of flavonoids in affective disorders."

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain."

But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention."

This heterogeneity makes altitude biologically informative for stroke research, but it does not justify treating natural altitude exposure as a single protective or harmful state. In this structured narrative review, we searched and organized the literature to ask which altitude-associated hypoxic cues resemble or reveal mechanisms compatible with cerebral ischemic tolerance, and what level of evidence supports that claim. We separate long-term adaptation, short-term acclimatization, chronic or excessive environmental hypoxia, and experimental hypoxic conditioning; define direct, supportive, and indirect evidence tiers; and integrate neurovascular-unit biology with multi-omics and stroke pathophysiology. Experimental hypoxic preconditioning remains the clearest direct evidence that a defined sublethal hypoxic stimulus can induce a time-limited tolerant state. In contrast, human high-altitude epidemiology, physiology, and genetics mainly constrain the clinical context and nominate candidate pathways rather than prove stroke-specific protection. We also emphasize that chronic hypoxia can be maladaptive through endothelial dysfunction, oxidative stress, erythrocytosis, thrombogenicity, blood-brain barrier impairment, and microvascular injury. Across neurovascular-unit cell types, a transparent evidence-weighting framework prioritizes endothelial biology because of its direct connection to BBB stability, effective reperfusion, hemorrhagic transformation risk, and no-reflow, while neurons, astrocytes, microglia, oligodendrocyte-lineage cells, and pericytes require different degrees of causal and human validation. We argue that the most productive path forward is not to label altitude as protective, but to use altitude-related biology to prioritize testable, stroke-facing hypotheses regarding BBB stability, microvascular patency, metabolic support, inflammatory thresholds, white-matter resilience, and biomarker-defined conditioning windows."

Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis. Consequently, our findings indicate that Blautia massiliensis enhances cognitive function whereas Blautia faecis impairs it, and we speculate that differential acetate production may contribute to these opposing effects."

This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications."

"abstract_text": "ID: 42488390\nTitle: The effect of concurrent neural injuries on hemorrhage.\nAbstract: Spinal cord injury (SCI) is often accompanied by additional tissue damage (polytrauma) that amplifies inflammation and activates pain pathways. The latter has been studied by engaging nociceptive fibers using electrical stimulation or capsaicin caudal to a thoracic SCI. Nociceptive stimulation 1\u202fday after SCI increases hemorrhage, amplifying secondary tissue loss. Noxious stimulation also promotes hemorrhage after a traumatic brain injury (TBI). A common form of polytrauma after SCI involves a TBI. The current study examines whether a concurrent TBI promotes hemorrhage after SCI. This also allowed us to evaluate whether a concurrent SCI promotes brain hemorrhage after TBI. Animals received a thoracic SCI and a concurrent brain surgery (anesthesia alone, craniectomy, or TBI). Other animals received a TBI to the frontal region and a concurrent spinal surgery (anesthesia alone, laminectomy, or SCI). Tissue was collected 24\u202fh later, sectioned, and the extent of brain/spinal cord hemorrhage was quantified. Sham controls were included to verify a remote injury (SCI/TBI) does not induce hemorrhage in the absence of local neural damage. A concurrent TBI with a SCI amplified hemorrhage in the spinal cord. A craniectomy had an intermediate effect on hemorrhage. Additionally, concurrent SCI with a TBI increased hemorrhage in the brain with a more modest effect. The results provide a link between hemorrhage development and concurrent neural injuries, with greater hemorrhage observed after SCI in animals with a concurrent TBI. SCI modestly impacted hemorrhage after TBI. These results provide a basis to further investigate the mechanisms responsible for interactions between multiple neurotraumatic injuries."

Although glial cells are essential for maintaining neural homeostasis under stress, how specific glial subtypes remodel metabolism to promote hypoxia tolerance remains poorly understood. Here, we identify a Notch-dependent lipid metabolic program in excitatory amino acid transporter 1 (Eaat1)-positive glia that supports hypoxia adaptation in the developing Drosophila larval brain. Using stimulated Raman scattering (SRS) microscopy combined with deuterium-labeled metabolic probes, we visualized substrate-specific metabolic activity in vivo at subcellular resolution. In control, non-adapted flies, we found that acute hypoxia markedly increased de novo lipogenesis in Eaat1-positive glia. In flies adapted to chronic hypoxia, Eaat1-positive glia exhibited a pre-programmed metabolic shift, characterized by reduced glucose-derived lipogenesis and enhanced acetate-derived lipid synthesis. Constitutive activation of Notch signaling in Eaat1-positive glia was sufficient to phenocopy this acetate-favored lipogenic state, suggesting that Notch promotes metabolic plasticity under oxygen-limited conditions. To define the transcriptional programs associated with this response, we performed single-nucleus RNA sequencing (snRNA-seq) of the developing Drosophila central nervous system and mapped Eaat-1expressing cell populations across hypoxia and Notch activation. Notch activation reshaped hypoxia-associated transcriptional responses and counteracted metabolic suppression caused by low oxygen. Together, our findings identify Eaat1-positiveglia as a metabolically adaptive glial population and reveal a conserved Notch-regulated mechanism that rewires lipid metabolism to support hypoxia tolerance in the developing brain. These results provide insight into glial metabolic strategies that may be relevant to hypoxia-associated neurological conditions, including neonatal hypoxic-ischemic brain injury and ischemic stroke."

Thirty-five university students (mTBI = 9; controls = 26) aged 18-24 years completed phonemic (FAS) and semantic (animal naming) verbal fluency tasks. Total correct responses, mean cluster size and number of switches were analysed. Compared with controls, individuals with mTBI produced fewer 'S' words (z = 2.66, P = 0.007, r = 0.45) and semantic switches (z = 2.45, P = 0.015, r = 0.41). Both groups were significantly different in semantic and phonemic clusters (mTBI: z = 2.22, P = 0.026, r = 0.74; controls: z = 3.51; P < 0.001, r = 0.69). No group differences were observed for phonemic switching. Findings indicate subtle reductions in cognitive flexibility and verbal productivity in individuals with chronic mTBI. Clustering and switching analyses in verbal fluency tasks may detect subtle, executive deficits in individuals with chronic mTBI that are not captured by total word count alone. These findings support the feasibility of subcomponent verbal fluency measures as sensitive tools for long-term mTBI assessment and monitoring."

Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke."

Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis.

With limited disease-modifying pharmacotherapies, lifestyle interventions have emerged as compelling, evidence-based avenues for prevention and early management. This review integrates mechanistic, translational, and clinical insights on major modifiable behaviours, physical activity, diet, intermittent fasting, sleep regulation, and gut-microbiome-based approaches that collectively shape cognitive ageing. Aerobic, anaerobic, and resistance exercises exert neuroprotective effects by activating BDNF-TrkB signalling, enhancing hippocampal neurogenesis, improving synaptic plasticity, and stimulating peripheral myokines (CTSB, IGF-1, GPLD1) that cross the blood-brain barrier to support neuronal resilience. Dietary interventions such as the Mediterranean, Mediterranean- DASH Intervention for Neurodegenerative Delay (MIND), and ketogenic diets mitigate AD pathology by reducing oxidative stress, inhibiting A\u03b2 deposition, improving mitochondrial efficiency, and modulating APOE4-linked metabolic vulnerability. Intermittent fasting induces a metabolic shift toward ketone utilisation, activates autophagy pathways (AMPK, SIRT3, Nrf2), remodels the gut microbiome, and promotes angiogenesis through GDF11 signalling. The gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation, and enhanced neuronal survival. Meanwhile, sleep quality, particularly slow-wave sleep, optimises glymphatic clearance and prevents the pathological accumulation of A\u03b2 and tau. Collectively, the evidence suggests that multidomain lifestyle approaches offer synergistic benefits that exceed those of individual interventions, representing promising strategies for delaying cognitive decline. However, gaps remain regarding dose-response relationships, personalised protocols for APOE4 carriers, and long-term validation in diverse populations. Strengthening these research directions is crucial for integrating lifestyle medicine into preventive neurology and public health frameworks."

However, pharmacological interventions that precisely modulate the gut microbiota in DRE have not yet been fully explored. This review aims to propose a systematic hypothesis that Dipeptidyl peptidase-4 inhibitors (DPP-4is) may alleviate peripheral and central pathological damage by regulating the \"gut microbiota-short-chain fatty acids (SCFAs) -glucagon-like peptide-1 (GLP-1) axis\", thereby reducing susceptibility to DRE. Existing studies indicate that: (1)DPP-4is possess neuroprotective effects in experimental epilepsy models, partly by enhancing endogenous GLP-1 signaling. (2)DPP-4is have been reported to modulate gut microbiota composition and increase the abundance of SCFA-producing bacteria in metabolic diseases. (3)SCFAs can promote GLP-1 secretion by activating free fatty acid receptors (FFAR2/3) and improve intestinal barrier function and inflammatory status in metabolic and neurodegeneration disease. However, it remains unclear whether this pathway mediates the effects of DPP-4is in epilepsy. (4)Enhanced peripheral GLP-1 signaling can further influence central nervous system homeostasis, including enhancing inhibitory synaptic transmission, attenuating neuroinflammation, oxidative stress, and inhibiting neuronal apoptosis, thereby reducing susceptibility to seizures.

Multiple studies consistently demonstrate that acetate supplementation suppresses neuroinflammation (reducing pro-inflammatory cytokines) and protects against cognitive decline through the restoration of BDNF-related pathways.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis confirms that the modulation of the gut microbiota to increase short-chain fatty acid (SCFA) production\u2014specifically acetate\u2014serves as a robust therapeutic intervention against hypoxia-induced neuroinflammation and cognitive impairment. Evidence establishes that acetate acts as a downstream mediator for beneficial gut bacteria, effectively mitigating hippocampal inflammation and protecting neuronal integrity, often through the subsequent upregulation of BDNF and related neuroplasticity signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis functions as a critical nexus for neuroprotection, where microbial metabolites serve as key signaling molecules. Chronic intermittent hypoxia (CIH) disrupts this homeostasis, leading to gut dysbiosis, systemic inflammation, and cognitive dysfunction. Research indicates that specific bacterial strains, such as *Bifidobacterium pseudolongum*, function to restore acetate levels. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells.\n\nThe mechanism by which acetate mitigates injury involves the downregulation of neuroinflammatory mediators and the preservation of synaptic function. In particular, the restoration of gut microbiota in hypoxic or aging models consistently correlates with higher BDNF levels. Evidence demonstrates that the gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation. This restoration of systemic and local metabolic homeostasis is essential for promoting BDNF-mediated neuroplasticity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate is not merely a metabolic byproduct but a specific regulator of cGAS-STING-mediated PANoptosis.\n* The effect of acetate can be bypassed by direct enteral supplementation, confirming the causal link between acetate depletion and neurocognitive vulnerability.\n* High-altitude adaptation and hypobaric hypoxia create unique metabolic demands that probiotics can address via \"dual-track\" metabolic reprogramming.\n* The interaction between gut microbial SCFA production and hippocampal BDNF signaling is conserved across multiple distinct stress models (hypoxia, alcohol consumption, and aging).\n* Acetate's role in the gut-brain axis is inherently linked to lipid metabolism, suggesting that neuroprotective effects involve more than just neurotransmitter modulation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

These effects mimic key features of neurodegenerative diseases and share mechanistic overlap with adverse outcomes of airborne environmental exposures that compromise oxygen homeostasis through mechanisms involving Hypoxia-Inducible Factor 1-alpha (HIF-1\u03b1) stabilization, proteasome dysfunction, and gut-brain axis disruption. In this study, C57BL/6 mice were exposed to 12% O2 for 2\u00a0months and received oral probiotics supplementation, which rescued short-term memory deficits in the novel object recognition test, reduced hippocampal HIF-1\u03b1 accumulation, restored prolyl hydroxylase domain protein 2 (PHD2) and ubiquitin-proteasome pathway, and attenuated neuroinflammation and apoptosis, while elevating brain-derived neurotrophic factor (BDNF). Probiotics also normalized plasma gut hormones (glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and leptin), enhanced ileal tight junction proteins (zonulin-1, occludin and claudin) in Ileal tissue, countered gut microbiota \u03b2-diversity shifts and restored beneficial bacterial metabolites with improved predicted metabolic pathways. These findings provide preclinical evidence that probiotics oral supplementation can restore gut-brain axis homeostasis, and mitigate chronic hypoxia related neuroinflammation, offering a potential therapeutic strategy against neurodegeneration triggered by oxygen\u2011depriving environmental and pathological conditions.\n\nID: 42398656\nTitle: Ethyl acetate extract of Poecilobdella manillensis Lesson ameliorates ischemia stroke through inhibiting cell apoptosis and suppressing TLR4/NF-\u03baB-mediates neuroinflammation.\nAbstract: Poecilobdella manillensis Lesson is a well-recognized medicinal leech in traditional Chinese medicine and Guangxi Zhuang ethnic medicine. It has long been used to activate blood circulation and remove blood stasis for the treatment of ischemic stroke. Modern pharmacological research has verified its potent anticoagulant and anti-inflammatory activities. Current studies mainly focus on its polypeptide components that exert antithrombotic effects to improve cerebral ischemia, while the neuroprotective potential and related mechanisms of its small-molecule constituents remain largely unclear. This study aimed to investigate the therapeutic effects of the ethyl acetate extract (EA) of P. manillensis on cerebral ischemia-reperfusion injury and to clarify its underlying molecular mechanism. The chemical constituents of EA were identified by UPLC-Q-TOF-MS/MS. Network pharmacology and molecular docking were used to predict and verify core targets and pathways. Neuroprotective and anti-inflammatory effects of EA were evaluated in a rat MCAO/R model, OGD/R-injured SH-SY5Y cells, and LPS-stimulated BV2 cells, using histological staining, Western blot, immunohistochemistry, and RT-qPCR. Seven small-molecule components were identified in EA, and 314 overlapping targets related to ischemic stroke were screened. Network analysis showed that TLR4 was the core target, and the main enriched pathways included NF-\u03baB, Toll-like receptor, apoptosis and TNF signaling pathways. Consistent with the predicted results, EA significantly reduced cerebral infarct volume and improved neurological deficits in MCAO/R rats, and inhibited neuronal apoptosis and microglial inflammation in vivo. In vitro, EA notably improved the survival of OGD/R-injured neurons and suppressed LPS-induced inflammatory responses in BV2 cells. Meanwhile, EA markedly downregulated the expression of TLR4/NF-\u03baB and NLRP3 inflammasome-related molecules. The present study demonstrated that EA protects against cerebral ischemia-reperfusion injury by inhibiting neuronal apoptosis and TLR4/NF-\u03baB-mediated neuroinflammation. These findings provide a scientific basis for the traditional clinical application of P. manillensis and suggest that EA could serve as a potential therapeutic candidate for ischemic stroke.\n\nID: 42354990\nTitle: The Gut-Brain-Muscle Axis: Microbial Regulation of Neuromuscular Aging and Cognitive Frailty.\nAbstract: Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, has emerged as a major challenge in aging populations and is closely linked to sarcopenia, neurodegeneration, and chronic inflammation. Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity.\n\nID: 42354205\nTitle: Fermented Dendrobium officinale Ameliorates Sleep Deprivation-Induced Depressive-like Behaviors by Attenuating Neuroinflammation and Restoring 5-HT Synthesis via the Gut-Brain Axis.\nAbstract: Chronic sleep deprivation (SD) disrupts gut-brain axis (GBA) homeostasis and is closely associated with gut microbiota dysbiosis, neuroinflammation, and depression-like behaviors. This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice. It reshaped gut microbial structures, enriched beneficial bacteria taxa such as Dubosiella, [Eubacterium]_coprostanoligenes_group, and Allobaculum, and increased SCFA levels. FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance. In addition, FDO upregulated BDNF, PSD-95, and SYN expression and reduced corticosterone (CORT) levels. Compared with DO, FDO showed more pronounced regulatory effects. Correlation analysis suggested that 5-HT may link gut microbial metabolites, inflammation, and synaptic plasticity. In summary, these findings support FDO as a potential GBA-targeted functional food for SD-related depressive-like behaviors.\n\nID: 42309243\nTitle: Ayurvedic Herbs as neurogenesis modulators: Current understanding on their potential therapeutic relevance in enhancing neuroplasticity and cognition in aging and neurodegeneration.\nAbstract: Ayurvedic medicine, an ancient Indian health system, promotes a category of Ayurvedic herbs (AH) known as Medhya Rasayanas (nootropic rejuvenators) for cognitive enhancement and neuroprotection. Currently, AH are increasingly being studied for their potential to boost neuroplasticity and neurogenesis, as they can stimulate the growth of new neurons, improve the complexity of existing ones, and support cognitive resilience. Recent evidence-based research suggests the potential to use these AH and their formulations to develop new therapies for addressing cognitive decline during aging and neurodegenerative disorders (NDD). Neurogenesis is known to be compromised in mild cognitive impairment (MCI) and is impaired early in animal models of Alzheimer's disease (AD), suggesting that rescuing neurogenesis may restore hippocampal plasticity and attenuate neuronal vulnerability and memory loss. Several AH, including Brahmi (Bacopa monnieri), Gotu Kola (Centella asiatica), Ashwagandha (Withania somnifera), Shankhapushpi (Convolvulus pluricaulis), Guduchi (Tinospora cordifolia), and Yashtimadhu (Glycyrrhiza glabra), are well recognized for their cognitive-enhancing and neuroprotective properties. Further, in chronic stress models, the neurogenic effects of AH are proposed to be mediated by mechanisms including antioxidant and anti-inflammatory effects, modulation of neurotransmitters, and effects on the gut microbiota. Neurotrophins (particularly brain-derived neurotrophic factor -BDNF) are important mediators of neuroplasticity as they modulate multiple processes, including synaptic plasticity, axonal and dendritic growth, spine morphogenesis, and neurogenesis. BDNF is compromised in depression and recovered by conventional antidepressants. The antidepressant-like effects of AH are associated with the reversal of chronic stress-induced impairment in neuroplasticity, most notably through up-regulation of BDNF, activation of downstream signaling pathways, and increased neurogenesis in the hippocampus and/or prefrontal cortex. This review summarizes current developments regarding AH's propensity to enhance neuronal plasticity and its therapeutic role as a modulator of neurogenesis. It also emphasizes the importance of using them as adjuvant therapy to attenuate cognitive deficits associated with aging and neurodegeneration.\n\nID: 42300178\nTitle: Daily supplementation with egg yolk lipids from two eggs alleviated cognitive impairment in 5 \u00d7 FAD mice by restoring neuronal and synaptic function and regulating gut microbiota.\nAbstract: Eggs are recommended by dietary guidelines as an effective vehicle for DHA intake, yet direct evidence on the health effects and optimal dosage of egg yolk lipids against Alzheimer's disease (AD) remains limited. This study evaluated DHA-enriched egg yolk lipids in 5 \u00d7 FAD mice at doses of 1 and 2 g kg-1 day-1 for eight weeks, corresponding to human consumption of 1 or 2 eggs daily. The high-dose intervention (2 g kg-1) ameliorated cognitive deficits and neuronal damage by upregulating BDNF and NGF, improving synaptic plasticity (PSD95, SYN, Drebrin), increasing dendritic spine density, restoring cholinergic and glutamatergic neurons, and suppressing microglial activation-induced neuroinflammation (IL-6, IL-1\u03b2, IFN-\u03b3). Metabolomic and gut microbiota analysis revealed increased levels of neuroprotective metabolites (PC (20\u2009:\u20092/22\u2009:\u20096), neuroprotectin D1) and enhanced abundance of AD-beneficial genera including Muribaculaceae and Lachnospiraceae. This study provides direct experimental evidence supporting DHA-enriched egg yolk lipids as a dietary intervention strategy for AD, with an effective dosage of 2 g kg-1.\n\nID: 42263472\nTitle: Bifidobacterium pseudolongum alleviates chronic intermittent hypoxia-induced cognitive impairment by restoring acetate metabolism and suppressing hippocampal neuroinflammation and neuronal PANoptosis.\nAbstract: Obstructive sleep apnea, characterized by chronic intermittent hypoxia (CIH), is a common sleep disorder frequently accompanied by cognitive impairment. Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction. Targeting B.p and acetate may offer a promising therapeutic strategy for neuroprotection in OSA.\n\nID: 42260668\nTitle: Polygala oligosaccharide esters improve memory disorder by restoring gut microbiota homeostasis through the regulation of the \"gut-brain\" axis.\nAbstract: Yuanzhi (Polygala tenuifolia Willd.) possesses the effects of calming the spirit, enhancing intelligence, regulating the heart-kidney connection, eliminating phlegm, and reducing swelling. It is commonly used in the treatment of insomnia and forgetfulness. Previous studies have indicated that the oligosaccharide esters (OE) derived from Yuanzhi exhibit neuroprotective and memory-enhancing activities.\u00a0However, its underlying mechanisms, particularly those involving the gut-brain axis, remain unclear. This study aimed to investigate the therapeutic efficacy and underlying mechanisms of Oligosaccharide Esters (OE) from Polygala tenuifolia Willd. against memory dysfunction in mice, with a specific focus on the gut-brain axis. A mouse model of memory dysfunction was induced using D-galactose combined with AlCl\u2083. Behavioral tests, molecular biology techniques (histopathology, enzyme-linked immunosorbent assay (ELISA), immunohistochemistry, and Western blot), and multi-omics approaches (16S rRNA sequencing and lipidomic analysis) were employed to investigate the therapeutic efficacy of OE against memory dysfunction. Meanwhile, with the aid of fecal microbiota transplantation (FMT) assay, we observed the repair of brain and colonic tissues, inflammatory responses and intestinal permeability, further clarified the regulatory effect of OE on gut microbiota, and ultimately revealed the underlying mechanisms of OE mediated by the gut-brain axis. OE administration significantly enhanced learning and memory in MD mice, repaired neuronal damage in the hippocampal regions (CA1, CA3, DG) of the MD mouse brain, and increased the number of Nissl bodies. OE elevated the serum levels of BDNF and CREB and reduced the TMAO level; simultaneously, it enhanced the activities of SOD and GSH-Px and decreased the MDA content in the brain tissue. OE treatment modulated the relative abundance of the gut microbiota in MD mice, restored the microbial imbalance induced by memory deficits, and particularly affected the abundances of Firmicutes, Bacteroidetes, their ratio (F/B), and genera such as Ligilactobacillus. Lipidomics analysis indicated that OE exerts its therapeutic effects primarily by regulating the glycerophospholipid metabolism pathway, and a total of 17 key differential lipid metabolites were identified. Correlation analysis further revealed that the levels of key differential lipid metabolites, LysoPC(22:2) and PC(38:4), were significantly positively correlated with the levels of neuroprotective factors (CREB, BDNF) and the activities of antioxidant enzymes (SOD, GSH-Px), but were significantly negatively correlated with the harmful metabolite TMAO and the oxidative damage product MDA. In contrast, the lipid metabolite GPEA exhibited a trend opposite to that of LysoPC(22:2) and PC(38:4). Further investigation results demonstrated that OE could repair pathological damage in colon tissue, regulate the levels of the microbial metabolite TMAO and the neurotransmitter 5-HT, reduce the levels of pro-inflammatory factors (LPS, TNF-\u03b1, IL-6) in both the brain and colon, and inhibit the abnormal activation of astrocytes and the abnormal hyperphosphorylation of Tau protein. The results of correlation analysis indicated that beneficial bacteria [e.g., Ligilactobacillus) and beneficial lipids (e.g., LysoPC(22:2) and PC(38:4)] were collectively significantly negatively correlated with key pathological indicators (e.g., TMAO and TNF-\u03b1) and were positively correlated with the neurotransmitter (e.g., 5-HT). OE also significantly up-regulated the expression of tight junction proteins (Occludin, Claudin-5) in both brain and colon tissues, thereby structurally repairing the damaged gut-brain barrier. FMT experiments showed that FMT improved the learning and memory abilities of mice, repaired neuronal damage in the hippocampus (CA1, CA3, DG), and increased the number of Nissl bodies. In addition, FMT alleviated colonic tissue injury, attenuated inflammatory responses in the brain and colon, and reduced intestinal permeability in MD mice, exerting a therapeutic effect similar to that of OE. OE exerted anti-amnestic effects via the gut-brain axis, primarily by alleviating neuroinflammation and oxidative stress, restoring gut microbiota homeostasis, and regulating glycerophospholipid metabolism, ultimately improving learning and memory abilities in MD mice.\n\nID: 42251712\nTitle: Neuropsychopharmacological effects of Aronia melanocarpa: A narrative review.\nAbstract: This narrative review examines the neuropsychopharmacological effects of Aronia melanocarpa (black chokeberry), focusing on its potential in the prevention and treatment of neuropsychiatric disorders such as anxiety, depression, and cognitive decline. A comprehensive literature search across Web of Science, Scopus, and Google Scholar identified 29 original studies, based on in vitro, animal, and human research. Findings demonstrated that Aronia melanocarpa, rich in polyphenols like anthocyanins and proanthocyanidins, exerts cognitive-enhancing, anxiolytic-like, and antidepressant-like effects. These outcomes are mediated by mechanisms involving antioxidant activity, modulation of neurotransmitter systems, inhibition of monoamine oxidases, reduction of neuroinflammation, modulation of gut microbiota, and upregulation of brain-derived neurotrophic factor (BDNF). Animal models of Alzheimer's disease and stress-induced disorders, along with human clinical trials, corroborated these effects. The review underscores the therapeutic promise of Aronia melanocarpa nutraceuticals in neuropsychiatric health and highlights the need for further clinical validation.\n\nID: 42215424\nTitle: Lignans Alleviate Depression by Modulating the Gut-Brain Axis: Effect and Mechanism Based on Multi-Omics Analyses.\nAbstract: Major depressive disorder (MDD) is a highly disabling psychiatric illness characterized by persistent low mood and psychomotor retardation, often leading to cognitive impairment or even suicidality. As the pathogenesis remains poorly understood, the currently available treatment regimens are mostly symptomatic therapies with little satisfactory curative effect. The emerging paradigm of gut-brain axis has highlighted gut dysbiosis as a key etiological factor to elicit neuro-inflammation and jeopardize the central nervous system homeostasis. In this study, we evaluated the ameliorating effects of flaxseed lignans on the gut microbiome to regain the gut micro-environmental functionality and alleviate MDD. The lignans significantly mitigated the severity of disease and markedly altered the gut microbiota structure in the participants. In the MDD mouse model, the lignans reversed the experimental depression-like behaviors, repaired neural and gut damage and restored barrier integrity. Of great significance, the lignans elevated the levels of 5-hydroxytryptamine (5-HT), brain-derived neurotrophic factor (BDNF) and \u03b3-aminobutyric acid (GABA), and markedly attenuated microglial and systemic inflammation. Mechanistically, the lignans inhibited the IL-17/AP-1/NF-\u03baB axis through direct interaction with the Fos protein. In the BV-2 cells, the lignan enterolactone reduced levels of nitric oxide and pro-inflammatory cytokines, further validating the anti-inflammatory mechanism of the lignans. Together, these findings demonstrate that lignans exert potent antidepressant effects by modulating the gut-brain axis and resolving neuro-inflammation, providing useful information for the development of novel therapeutic strategies for MDD prevention and treatment.\n\nID: 42196538\nTitle: Flavonoids as Modulators of Neuroinflammation in Affective Disorders: A Narrative Review.\nAbstract: Affective disorders, including anxiety, depression, and bipolar disorder (BD), represent a global mental health burden with complex, multifactorial etiopathogenesis. Increasing evidence implicates neuroinflammation, oxidative stress, and dysregulation of neurotrophic and neurotransmitter systems as central mechanisms driving these conditions. Flavonoids, a structurally diverse class of plant-derived polyphenolic compounds abundantly found in fruits, vegetables, tea, and other dietary sources, have emerged as promising modulators of these pathophysiological pathways. This narrative review synthesizes current preclinical and clinical evidence on the role of flavonoids and related natural compounds in modulating neuroinflammation and affective disorders. We describe the major flavonoid subclasses-flavones, flavonols, isoflavones, anthocyanins, flavanones, and flavan-3-ols-and analyze their mechanisms of action, including inhibition of the NF-\u03baB/NLRP3 axis, reduction in pro-inflammatory cytokines, attenuation of oxidative stress via Nrf2 pathway activation, modulation of monoaminergic and GABAergic neurotransmission, promotion of Brain-Derived Neurotrophic Factor (BDNF)-mediated neuroplasticity, and regulation of the microbiota-gut-brain axis. Preclinical studies consistently demonstrate anxiolytic and antidepressant effects for compounds such as quercetin, luteolin, apigenin, and chrysin; however, clinical evidence remains limited and methodologically heterogeneous. Future research should prioritize bioavailability-enhanced formulations, standardized clinical trials, and biomarker-guided stratification to fully establish the therapeutic potential of flavonoids in affective disorders.\n\nID: 42125345\nTitle: Central Neurobiological Mechanisms of Acupuncture in Post-Stroke Depression: Multi-Target and Network-Based Regulation.\nAbstract: Post-stroke depression (PSD) is a common post-stroke complication with limited treatment options and significant adverse effects from conventional drugs. Acupuncture, a multi-target holistic non-pharmacological intervention, shows unique clinical advantages. This review provides the first systematic synthesis of the central neurobiological mechanisms underlying acupuncture's therapeutic effects on PSD. The identified mechanisms include promoting neuroplasticity via the BDNF/TrkB pathway and rebalancing neurotransmitter systems (monoamines and glutamate/GABA). Additionally, acupuncture inhibits microglial activation and TLR4/NF-\u03baB/NLRP3-driven neuroinflammation, restores mitochondrial homeostasis through AMPK-dependent autophagy, and modulates the gut microbiota-brain axis. Together, these findings elucidate the \"multi-target, network-based\" characteristics of acupuncture from a modern scientific perspective, providing a scientific basis for traditional Chinese acupuncture principles. By integrating recent mechanistic advances, this review addresses literature gaps and offers a theoretical foundation for optimizing clinical strategies, promoting mechanism-driven personalized interventions, and bridging traditional Chinese medicine with contemporary neuroscience.\n\nID: 42123660\nTitle: Butyrate Is Associated with the Antidepressant Effects of Weizmannia coagulans BC99: Functional Similarity of a Microbial Metabolite in the Microbiota-Gut-Brain Axis.\nAbstract: Butyrate, a short-chain fatty acid derived from the gut microbiota, has been linked to depression through correlational studies; however, whether it might act as a sufficient downstream mediator of the antidepressant effects of a probiotic remains poorly understood. To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting. Treatment with BC99 was associated with alleviation of CUMS-induced depressive-like behaviors, increased butyrate levels, reduced neuroinflammation (IL-1\u03b2, IL-6, LPS, and IL-4), and restored hippocampal BDNF levels. BC99 also enriched butyrate-producing bacterial taxa (e.g., Lactobacillus, Bifidobacterium, Faecalibaculum) and normalized tryptophan and sphingolipid metabolism. Notably, sodium butyrate alone recapitulated several of the behavioral and anti-inflammatory effects observed with BC99 and, as shown by Western blot, partially restored hippocampal BDNF/TrkB/CREB signaling, which was impaired in CUMS rats. Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression.\n\nID: 42108470\nTitle: Pulmonary microbiota-associated formononetin modulates microglial activation in asthma-related anxiety.\nAbstract: Asthma is frequently accompanied by anxiety disorders, yet the mechanisms linking asthma to neuropsychiatric symptoms remain poorly defined. Here, we investigated the contribution of the pulmonary microbiota and its metabolites to anxiety-like behavior in an ovalbumin-induced asthma mouse model. Behavioral testing and resting-state functional magnetic resonance imaging revealed anxiety-like phenotypes and altered hippocampal function in a subset of asthmatic mice that were susceptible to anxiety-like behavior. These mice exhibited hippocampal neuroinflammation and neuronal damage, accompanied by dysbiosis of the pulmonary microbiota. Intratracheal transplantation of lung microbiota from anxiety-susceptible donors induced similar behavioral changes in recipient mice, indicating a causal role of the pulmonary microbiota. Untargeted metabolomics identified formononetin as a candidate metabolite positively correlated with the relative abundance of Acidobacteria. Intratracheal administration of formononetin alleviated anxiety-like behaviors, reduced hippocampal inflammation and injury, and restored hippocampal BDNF/TrkB signaling. However, these effects were abolished by the TrkB antagonist ANA-12. Transcriptomic and immunofluorescence analyses suggested that formononetin acts through modulation of hippocampal microglia. In vitro and small RNA sequencing analyses further demonstrated that formononetin promotes BDNF production by downregulating miR-1912-3p, thereby relieving its translational repression in microglia. Together, these findings reveal a lung-brain axis in which a pulmonary microbiota-associated metabolite modulates microglial function to alleviate asthma-related anxiety.\n\nID: 42104939\nTitle: Ameliorative Effects of Butyrylated Starch on Cognitive Dysfunction in d-Galactose-Induced Aging Mice: A Comparative Analysis with Exogenous Butyrate and Resistant Starch.\nAbstract: Butyric acid improves cognitive dysfunction. Therefore, butyrylated starch acts as a butyrate carrier and resistant starch to produce butyric acid, potentially improving cognitive dysfunction. In the d-galactose-induced aging mice model, BNMS2 effectively improved cognitive dysfunction and outperformed sodium butyrate and high-amylose maize starch. BNMS2 ameliorated cognitive behavior and brain histopathology, decreased GFAP, IBA-1, A\u03b2, AChE, MDA, IL-6, IL-1\u03b2, and TNF-\u03b1 levels, and increased BDNF, PSD-5, GSH-Px, and SOD levels to mitigate neuronal damage, oxidative stress, and inflammation. BNMS2 also produced abundant butyric acid, enhanced the abundance of beneficial bacteria (Alistipes, Parasutterella, Parabacteroides, Lachnospiraceae_UCG-006, Muribaculum) and molecular transport and signaling functions, suppressed d-galactose-induced harmful bacteria proliferation and galactose metabolism, and increased dopamine, glutamic acid, \u03b3-aminobutyric acid, glutamine, tryptophan, N-acetylneuraminic acid, and nicotinamide levels. Overall, BNMS2 mitigated neural damage, oxidative stress, and inflammation by enhancing butyric acid production, modulating gut microbiota, and synergistically increasing cognitive-related metabolites, thereby mitigating cognitive dysfunction.\n\nID: 42099162\nTitle: A Multimodal Framework for Alzheimer's Prevention: Diet, Exercise, Fasting, Sleep, and Gut Microbiota.\nAbstract: Alzheimer's Disease (AD) and related dementias arise from a multifactorial interplay of genetic susceptibility, metabolic dysfunction, neuroinflammation, and lifestyle determinants. With limited disease-modifying pharmacotherapies, lifestyle interventions have emerged as compelling, evidence-based avenues for prevention and early management. This review integrates mechanistic, translational, and clinical insights on major modifiable behaviours, physical activity, diet, intermittent fasting, sleep regulation, and gut-microbiome-based approaches that collectively shape cognitive ageing. Aerobic, anaerobic, and resistance exercises exert neuroprotective effects by activating BDNF-TrkB signalling, enhancing hippocampal neurogenesis, improving synaptic plasticity, and stimulating peripheral myokines (CTSB, IGF-1, GPLD1) that cross the blood-brain barrier to support neuronal resilience. Dietary interventions such as the Mediterranean, Mediterranean- DASH Intervention for Neurodegenerative Delay (MIND), and ketogenic diets mitigate AD pathology by reducing oxidative stress, inhibiting A\u03b2 deposition, improving mitochondrial efficiency, and modulating APOE4-linked metabolic vulnerability. Intermittent fasting induces a metabolic shift toward ketone utilisation, activates autophagy pathways (AMPK, SIRT3, Nrf2), remodels the gut microbiome, and promotes angiogenesis through GDF11 signalling. The gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation, and enhanced neuronal survival. Meanwhile, sleep quality, particularly slow-wave sleep, optimises glymphatic clearance and prevents the pathological accumulation of A\u03b2 and tau. Collectively, the evidence suggests that multidomain lifestyle approaches offer synergistic benefits that exceed those of individual interventions, representing promising strategies for delaying cognitive decline. However, gaps remain regarding dose-response relationships, personalised protocols for APOE4 carriers, and long-term validation in diverse populations. Strengthening these research directions is crucial for integrating lifestyle medicine into preventive neurology and public health frameworks.\n\nID: 42097207\nTitle: Galacto-oligosaccharides ameliorate polystyrene nanoplastic-induced anxiety- and depression-like behaviors via a gut-initiated serotonergic cascade.\nAbstract: As emerging environmental contaminants, micro- and nanoplastics (MNPs) raise neurotoxic concerns. However, the mechanisms underlying their induction of emotional disorders remain poorly understood. In particular, intervention-oriented and functionally validated strategies for prevention and control are still lacking. To address this, we conducted a 28-day repeated oral exposure study in mice using a gradient of polystyrene nanoplastics (PS-NPs; 2, 10, and 50\u00a0mg/kg/day) spanning environmentally relevant doses, systematically assessing impacts along the microbiota-gut-brain axis. Our results showed that PS-NP exposure induced dose-dependent anxiety- and depression-like behaviors, with fluorescence tracing revealing predominant gut accumulation and limited brain distribution. Mechanistically, exposure induced gut microbiota dysbiosis, intestinal barrier impairment, and lipopolysaccharide translocation, ultimately leading to systemic inflammation and neuroinflammation. Serum biochemical analysis showed that gut dysbiosis initiates host tryptophan metabolism toward the kynurenine pathway by triggering inflammation and subsequent indoleamine 2,3-dioxygenase 1(IDO1) activation. Consistently, hippocampal transcriptomic and biochemical analyses confirmed decreased 5-HT levels and suppression of the downstream 5-HT1A-cAMP-PKA-CREB-BDNF neurotrophic cascade, demonstrating comprehensive serotonergic disruption from substrate depletion to receptor dysfunction. Notably, the prebiotic galacto-oligosaccharides (GOS) restored intestinal homeostasis and ameliorated these anxiety- and depression-like behavioral and metabolic deficits, exerting protective effects by counteracting the above pathway. Our work delivers a from-mechanism-to-solution understanding: it deciphers how microplastics disrupt the gut-brain axis to cause neurotoxicity and identifies GOS maintenance of intestinal health as a key mitigative strategy against plastic pollution risks. Therefore, maintaining intestinal health, particularly through dietary GOS, represents a viable strategy to mitigate the neurotoxicity induced by plastic pollution.\n\nID: 42062245\nTitle: From gut to brain: effects of fecal microbiota transplants from humans to rats on hippocampal gene regulation - a study on anorexia nervosa.\nAbstract: Fecal microbiota transplantation (FMT) has emerged as a novel approach for understanding anorexia nervosa (AN), a complex eating disorder characterized by severe underweight, fear of weight gain and distorted body image. Patients with AN show alterations in the gut microbiome, brain structure, and inflammatory processes, indicating the importance of the microbiome\u2012gut\u2012brain axis in AN pathology. This study aimed to investigate whether FMT from patients with AN into antibiotic-treated rats could transfer a phenotype associated with the disease inducing AN-like symptoms and hippocampal alterations. Female Wistar rats received antibiotics followed by FMT from healthy controls, patients with AN, or water. Gut microbiota effects were assessed through 16S rRNA gene sequencing, alongside post-mortem analyses of glial cells, neurogenesis markers, and inflammatory markers. The results revealed dysregulated microbial diversity after antibiotic treatment, which was partially restored after FMT. Successful transfer of human bacterial species was observed, but AN-like symptoms and changes in glial/neuronal counts were not detected. Notably, a decrease in hippocampal Bdnf expression was detected in the antibiotic control group, which was reversed by healthy control stool transplantation but not in the AN-transplanted group. Similar patterns were observed for neuroinflammation and Mki67, a marker of cell neogenesis. These findings suggest potential links between microbial changes, neuroinflammation and neuroplasticity in the hippocampus with the potential to correct deficits with FMT. Future studies should extend these findings by exploring the combination of FMT and starvation phases to better understand the roles of specific microbial populations in neuroinflammatory processes and, ultimately, clinical outcomes in AN.\n\nID: 42036577\nTitle: Chronic Inflammation and Neuroprogression in the Pathophysiology in Major Depression.\nAbstract: Major depressive disorder (MDD) results from interactions between genetic and environmental factors, contributing to neuroinflammation and neurodegeneration. Chronic stress, poor diet, and environmental toxins exacerbate inflammatory responses, leading to neuronal dysfunction and disease progression. Stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis promotes a pro-inflammatory state, impairing neuroplasticity and cognition. Likewise, unhealthy diets disrupt gut microbiota, increasing systemic inflammation, while anti-inflammatory diets offer neuroprotection. Exposure to air pollutants and heavy metals induces oxidative stress and mitochondrial dysfunction, further worsening neuroinflammation. Genetic predisposition influences inflammatory responses, with polymorphisms in interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-\u03b1), and brain-derived neurotrophic factor (BDNF), affecting MDD susceptibility and neuronal resilience. Given the inflammatory basis of MDD, treatment should extend beyond traditional monoaminergic therapies. Emerging approaches, including ketamine and monoclonal antibodies targeting inflammatory pathways, show promise. Lifestyle interventions such as physical exercise and anti-inflammatory diets may complement pharmacological treatments by reducing neuroinflammation and promoting neuronal health. This chapter explores the complex interactions between genetic and environmental factors in MDD, emphasizing their role in neuroinflammation and highlighting potential therapeutic strategies.\n\nID: 42021774\nTitle: Serum microbiome-related metabolites-including short-chain fatty acids and indole derivatives-predict outcome and delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage: a two-timepoint LC-MS study.\nAbstract: Delayed cerebral ischemia (DCI) remains a major determinant of poor outcome after aneurysmal subarachnoid hemorrhage (aSAH). Growing evidence suggests that gut microbiota-derived metabolites, including short-chain fatty acids (SCFAs) and tryptophan-related indole compounds, modulate neuroinflammation and cerebrovascular vulnerability. However, their temporal dynamics and clinical relevance after aSAH are insufficiently characterized. In this prospective observational study, 80 consecutive patients with aSAH were enrolled at a tertiary neurocritical care center. Serum concentrations of SCFAs (propionic, butyric, isobutyric, valeric, isovaleric, caproic acids) and tryptophan-derived metabolites (tryptophan, indole-3-propionic acid [IPA], indole-3-acetic acid, indole-3-lactic acid) were quantified using LC-MS on Day 1 and Day 9 after hemorrhage. Functional outcome at 3\u202fmonths was assessed using the modified Rankin Scale (mRS), and DCI was diagnosed according to consensus criteria. Associations were analyzed using non-parametric statistics, ROC analyses, and multivariable logistic regression adjusted for established clinical confounders. Patients with unfavorable 3-month outcomes (mRS 4-6) showed significantly lower Day 1 levels of propionic, isobutyric, and isovaleric acids, persistently reduced tryptophan at both time points, and markedly lower IPA concentrations on Day 9. DCI was associated with reduced tryptophan and propionic acid levels on both days and a pronounced decrease in IPA on Day 9. Tryptophan and propionic acid demonstrated excellent discriminative performance for outcome and DCI (AUCs up to 0.99). In multivariable models, low Day 1 propionic acid and low Day 9 IPA independently predicted unfavorable outcome, while Day 9 tryptophan, IPA, and propionic acid independently predicted DCI. Distinct temporal alterations in gut microbiota-derived metabolites after aSAH are strongly associated with functional outcome and DCI. SCFAs and tryptophan-related metabolites-particularly propionic acid, tryptophan, and IPA-emerge as promising biomarkers and potential mechanistic mediators in secondary brain injury after aSAH.\n\nID: 42021550\nTitle: Acupuncture: A Promising Non-Pharmacological Approach to Parkinson's Disease Management.\nAbstract: This review aims to elucidate the molecular mechanisms underlying the neuroprotective effects of acupuncture in preclinical models of Parkinson's disease (PD). In PD animal models, acupuncture inhibits oxidative stress by upregulating nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element (ARE), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) while reducing malondialdehyde (MDA) and lipid peroxidation. It regulates autophagy either independently of mammalian target of rapamycin (mTOR) or via mTOR activation, promoting alpha-synuclein (\u03b1-synuclein) clearance. Acupuncture also suppresses apoptosis (modulating Bcl-2-associated X protein (Bax)/B-cell lymphoma 2 (Bcl-2)) and pyroptosis (inhibiting NLR family pyrin domain containing 3 (NLRP3) inflammasome and gasdermin D (GSDMD)). It enhances neurogenesis through brain-derived neurotrophic factor (BDNF)/extracellular signal-regulated kinase (ERK)/cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB) and glial cell line-derived neurotrophic factor (GDNF) signaling, promoting neural stem cell proliferation and differentiation. Furthermore, acupuncture reduces neuroinflammation by decreasing microglial activation, cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-\u03b1), and interleukin-1 beta (IL-1\u03b2). It also modulates gut microbiota composition (e.g., increasing butyrate-producing bacteria like Butyricimonas and reducing pro-inflammatory Erysipelotrichaceae and Bacteroides) and influences lipid metabolism, thereby mitigating dopaminergic neuron loss and motor deficits. Preclinical evidence demonstrates that acupuncture exerts multi-target neuroprotective effects against PD through pathways involving oxidative stress, autophagy, apoptosis/pyroptosis, neurogenesis, neuroinflammation, and gut microbiota-lipid metabolism crosstalk. However, limitations include a focus on preventive rather than reversal effects, lack of long-term efficacy data, and heterogeneity in acupoint selection. Further mechanistic and standardization studies are warranted.\n\nID: 41991715\nTitle: Exploring the lung-brain axis in perioperative neurocognitive disorders: a potential therapeutic target.\nAbstract: Perioperative neurocognitive disorders (PND), primarily including postoperative delirium (POD) and postoperative cognitive dysfunction (POCD), are common and serious complications in elderly surgical patients. However, the exact mechanisms underlying PND are not fully understood. The lung-brain axis has recently been recognized as an important pathway in neurodegenerative diseases such as Alzheimer's disease (AD). Given that PND shares pathological features with AD, such as amyloid-\u03b2 (A\u03b2) accumulation, the lung-brain axis may also represent a plausible mechanistic contributor to PND. Furthermore, elderly surgical patients often receive inhalation anesthetics and undergo mechanical ventilation during general anesthesia, which directly affect the lungs and may alter the pulmonary microenvironment. Therefore, we hypothesize that the lung-brain axis plays a role in the development of PND. In this article, we discuss potential mechanisms by which surgery and anesthesia-especially inhalation anesthetics and mechanical ventilation-may influence cognitive function via the lung-brain axis. Potential mechanisms include changes in the pulmonary microbiota, secretion of brain-derived neurotrophic factor, and lung-derived inflammatory responses. These pathways may disrupt the blood-brain barrier, promote neuroinflammation, and exacerbate A\u03b2 deposition, ultimately leading to cognitive impairment. Exploring the role of the lung-brain axis could provide new insights into PND pathophysiology and reveal potential targets for prevention and treatment of PND by targeting pulmonary-mediated cascades.\n\nID: 41962264\nTitle: Anshen Bunao Syrup alleviates depression on CUMS rats by reducing neuroinflammation: Integral insights from transcriptomics, microbiomics, and metabolomics.\nAbstract: Anshen Bunao Syrup (ABS), a traditional Chinese medicinal formula, is widely used to treat neurological disorders such as insomnia, dizziness, and neurasthenia. However, its antidepressant effect and underlying mechanisms remain insufficiently characterized. This study aims to comprehensively evaluate the antidepressant effect of ABS in a rat model, and to elucidate the underlying mechanism. Chronic unpredictable mild stress (CUMS) induced depressive rats were used to evaluate the antidepressant effect of ABS. Histopathological alterations in the hippocampus and colonic mucosa were examined using Nissl and H&E staining. Microglial activation was evaluated by Iba-1 immunohistochemical staining. Gut microbiota composition and metabolic profiles were analyzed using 16S rRNA sequencing and untargeted metabolomics. Differential gene expression and pathway regulation were investigated by transcriptomics and confirmed by Western Blot (WB). ABS significantly ameliorated depressive-like behaviors and elevated dopamine and 5-Hydroxytryptamine levels in cortical regions. Furthermore, ABS mitigated hippocampal neuronal damage, suppressed microglial overactivation and reduced oxidative stress in the cortex. 16S rRNA sequencing analysis showed that ABS exerted antidepressant effects via modulation of the \"microbiota-gut-brain\" axis, particularly by altering intestinal microbiota composition, enhancing gut function, and suppressing HPA axis hyperactivity. Metabolomics revealed that ABS corrected metabolic disturbances, and alleviated inflammation-related metabolic disturbances, while transcriptomics indicated regulation of the Npas4-BDNF-PI3K/AKT signaling pathway, which was further confirmed by WB. ABS significantly ameliorated depression in a CUMS rat model, primarily through coordinated regulation of gut microbiota, metabolic homeostasis, and the Npas4-BDNF-PI3K/AKT signaling pathway, providing integrative mechanistic insights into its antidepressant effects.\n\nID: 41935130\nTitle: Protective effects of enteral acetate supplementation against brain injury in a rat model of necrotizing enterocolitis.\nAbstract: Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in preterm infants, often leading to brain injury. The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants.\n\nID: 41932583\nTitle: AICAR improves depression-like behaviors and is associated with hippocampal AMPK activation and modulation of neurogenesis and neuroinflammation in a microbiota disruption model.\nAbstract: Gut microbiota alterations are associated with the onset of depression; however, the underlying mechanisms remain unclear. Activation of hippocampal AMP-activated protein kinase (AMPK) in ulcerative colitis mice with disrupted gut microbiota balance produces antidepressant effects. However, the relationship between hippocampal AMPK and antibiotic treatment (ABX)-induced depression-like behavior remains unclear. Therefore, we aimed to investigate whether 5-aminoimidazole-4-carboxamide 1-\u03b2-d-ribofuranoside (AICAR), an AMPK activator, is associated with the prevention of ABX-induced depression-like behaviors. ABX mice exhibited depression-like behaviors, as evidenced by prolonged immobility and reduced sucrose preference. In the hippocampus of the ABX mice, Iba1 and pro-inflammatory microglial markers were upregulated, whereas brain-derived neurotrophic factor (BDNF), CD206, arginase-1, and interleukin-10 were downregulated. Additionally, levels of AMPK phosphorylation, cAMP response element binding protein (CREB), and tropomyosin-related kinase B (TrkB) were decreased. AICAR administration attenuated these behavioral and molecular alterations. Phosphorylated AMPK was colocalized with the neuronal marker-NeuN-and microglial marker-Iba1. AICAR ameliorated the reduction in hippocampal neuron proliferation and survival and reduced microglial activation-associated morphological changes in the hippocampus. These findings suggest that AICAR administration is associated with antidepressant-like effects, potentially involving enhanced neurogenesis and attenuation of neuroinflammation in the hippocampus of ABX mice. Together, this study highlights the significance of hippocampal AMPK phosphorylation in depression associated with gut microbiota alterations, and suggests a potential target for therapeutic interventions.\n\nID: 41868372\nTitle: Gut microbiota-derived EPA alleviates neuroinflammation associated with white matter injury by influencing H3K9ac/BDNF/TrkB pathway.\nAbstract: The objective of our investigation was to explore the features of gut microbiota dysbiosis and the concentrations of gut metabolites in relation to white matter injury (WMI). Furthermore, we sought to evaluate the influence of gut dysbiosis on neuroinflammation in WMI via intestinal metabolites, and its contribution to pathogenesis. A cerebral hypoxia-ischemia-induced WMI model was established in 3-day-old Sprague-Dawley rats. Liquid chromatography-mass spectrometry/gas chromatography-mass spectrometry analyses and 16S rRNA gene sequencing were undertaken to ascertain WMI biomarkers. Mechanistic experiments were used to analyse activation of the H3K9ac/BDNF/TrkB pathway and neuroinflammation. The analysis of 16S rRNA sequencing disclosed gut microbiota dysbiosis in WMI rats, quantified using linear discriminant analysis effect size. Overall, 341 differentially expressed metabolic markers between the WMI and Sham groups were discovered. The Kyoto Encyclopedia of Genes and Genomes network enhancement evaluation revealed significant downregulation of 20 metabolic processes in the WMI group, which is strongly related to changes in fecal microbial metabolites, and the synthesis process of unsaturated fatty acids was the most significant. Gut microbiota dysbiosis may influence WMI by downregulating metabolites such as eicosapentaenoic acid (EPA). Fecal microbiota transplantation increased EPA concentration in the brain tissue of WMI rats. Gut microbiota-derived EPA promoted H3K9ac and BDNF/TrkB expression and inhibited the transcription of pro-inflammatory TNF-\u03b1 and IL-1\u03b2 molecules. These EPA-mediated effects were reversed by TrkB inhibition. WMI induces gut dysbiosis involving down-regulation of unsaturated fatty acid synthesis. Fecal microbiota transplantation leads to increased levels of EPA. Gut microbiota-derived EPA increases levels of acetylated histone H3K9ac, causes activation of the BDNF/TrkB pathway, reduces neuroinflammation, and improves WMI-associated myelination disorders. It provides a basis for targeted treatment of white matter injury in the future.\n\nID: 41868184\nTitle: Advances and Therapeutic Potential of Anthraquinone Compounds in Neurodegenerative Diseases: A Comprehensive Review.\nAbstract: Rhubarb, traditionally used in China for neurological disorders, has recently attracted considerable scientific attention for its neuroprotective and cerebrovascular benefits. The main therapeutic components of rhubarb are anthraquinones, including emodin, aloe-emodin, chrysophanol, rhein, and physcion. Accumulating experimental evidence indicates that anthraquinones are of importance in neurodegenerative diseases (NDDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and multiple sclerosis. However, as a promising candidate for drug development, the mechanisms by which anthraquinones treat NDDs have not been systematically reviewed. Therefore, this article outlines the anti-neurodegenerative effects of anthraquinones, focusing on their molecular mechanisms. This article reviews recent research progress of anthraquinones in NDDs, focusing on their potential targets and pathways to provide new ideas for the intervention and treatment of NDDs. A comprehensive search of PubMed, Web of Science, and Google Scholar was conducted for articles on the intervention of anthraquinones in NDDs in the past 20 years. The collected information was then summarized and analyzed. Anthraquinones ameliorate NDDs through multiple mechanisms. They exhibit antioxidant and anti-inflammatory effects, protect mitochondria, and regulate microglial polarization. Furthermore, anthraquinones inhibit pyroptosis, apoptosis, tau phosphorylation, A\u03b2/\u03b1-synuclein aggregation, and acetylcholinesterase activity, while restoring metal homeostasis, activating estrogen receptors, modulating gut microbiota, increasing BDNF levels, and preserving blood-brain barrier permeability. More notably, these compounds play a neuroprotective role by mediating multiple signaling pathways and targets, including Nrf2, ERK1/2, PI3K/mTOR, ROS/TXNIP, SIRT1/PCG-1\u03b1, NLRP3, PI3K/Akt, MAPK, TLR4-NF\u03baB, CaM/CaMKIV, and Ca2+/EGFR/PLC\u03b3. The pleiotropic actions of anthraquinones highlight their potential as therapeutic candidates for NDDs, yet clinical validation remains essential. Future studies should emphasize rigorously designed clinical trials and optimized brain-targeted delivery platforms. This review consolidates current evidence to support their translational development.\n\nID: 41839449\nTitle: Resveratrol Attenuates Neuroinflammation and Gut-Brain Axis Dysfunction Induced by Lead and Cadmium Co-Exposure by Modulating Gut Microbiota in Rats.\nAbstract: Resveratrol (RSV), a dietary polyphenol widely present in traditional medicinal plants and foods, exhibits antioxidant and anti-inflammatory properties that are relevant to ethnopharmacological strategies for protecting against environmental neurotoxicants. Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin. RSV attenuated cytokine release, normalized goblet cells, reversed dysbiosis by restoring Lactobacillaceae/Prevotellaceae, and increased acetate, propionate, and butyrate. It reinstated 5-HT and GABA while reducing SP and restoring VIP across serum, colon, and hippocampus. RSV attenuated Pb-Cd-associated neurotoxicity and was accompanied by improved intestinal and BBB-related readouts, partial normalization of gut microbiota features and SCFA levels, and preservation of synaptic and neurotransmitter-related markers, consistent with a link to gut-brain axis function. This study is among the first to test RSV in a Pb-Cd co-exposure model using a multi-dose regimen with integrated behavioral, barrier, microbial, and neurochemical endpoints.\n\nID: 41824184\nTitle: Prebiotics attenuate depressive-like behavior, neuroinflammation and synaptic plasticity in Parkinson's disease by modulating butyrate-producing gut bacteria.\nAbstract: Parkinson's disease (PD) remains a challenging disease for treatment, which is usually polypharmacological. In addition to motor symptoms, non-motor symptoms such as depression are present in approximately 40% of patients, contributing to the loss of quality of life. In the last two decades, a growing body of evidence has emerged regarding the involvement of the microbiota-gut-brain axis in both PD and depression. Fructooligosaccharides (FOS) and galactooligosaccharides (GOS) are prebiotic fibers that can be fermented by the gut microbiota, which produce metabolites called short-chain fatty acids (SCFAs), whose effects can contribute to improvement in neurodegenerative and psychiatric conditions. This study analyzed the effects of FOS and GOS administration in a rotenone-induced PD model and demonstrated a relief of motor symptoms and depressive-like behavior, followed by an increase of brain serotonin and its respective receptor (SERT). FOS and GOS treatment also led to an increase in SCFAs-producing gut bacteria with significantly higher levels of serum and brain butyrate. Furthermore, in the intestine, prebiotics reduced the accumulation of \u03b1-synuclein, decreased inflammation, and improved the expression of zonula occludens and occludin. FOS and GOS also attenuated the loss of dopaminergic neurons and reduced neuroinflammation by decreasing \u03b1-synuclein, IBA-1, GFAP, iNOS, p-NFkB, and IL1-\u03b2 levels in the substantia nigra and prefrontal cortex. In addition, these prebiotics improved neuroplasticity by promoting the expression of butyrate receptors (GPR43 and GPR109), BDNF, p-CREB, and synaptic protein PSD-95. In conclusion, FOS and GOS administration attenuatted depressive-like behavior, neuroinflammation, and synaptic plasticity in Parkinson's disease by modulating butyrate-producing gut bacteria.\n\nID: 41794536\nTitle: Fermented red quinoa (FRQ) effectively mitigates chronic alcohol-induced cognitive impairment and hepatic steatosis through multi-mechanistic pathways.\nAbstract: Long-term alcohol consumption drives systemic damage through metabolites such as acetaldehyde, which trigger oxidative stress, inflammation, and gut dysbiosis. This study evaluated the protective effects of fermented red quinoa (FRQ) in an alcohol-exposed mouse model, with a focus on cognitive function. Male C57BL/6J mice were randomized into three groups for a 28-day study: a normal control, an alcohol-treated group gavaged with ethanol (1\u00a0mL/100\u00a0g\u00b7BW), and a group receiving the same ethanol dose co-administered with FRQ powder (human equivalent dose: 9\u00a0g/60\u00a0kg\u00b7BW). Our results demonstrated that fermentation with Lactobacillus kisonensis significantly increased the content of phenolic compounds (e.g., quercetin and veratric acid) in FRQ. FRQ intervention improved cognitive function, ameliorated synaptic structural impairment and blood-brain barrier disruption, and attenuated hepatic steatosis. The protective mechanisms involved three pathways: 1) The specific phenolic compounds in FRQ promoted alcohol metabolism by regulating ADH/ALDH activity, leading to reduced acetaldehyde levels. As a primary initiating pathway, this metabolic enhancement dominantly attenuated subsequent oxidative stress and inflammation, mitigating injury in the liver, brain, and colon. 2) It directly modulated AP-1 subunits (\u0394FOSB/JUND), restored BDNF, and rebalanced the glutamate/GABA systems. 3) It regulated the gut-liver-brain axis by remodeling the gut microbiota (e.g., enriching butyrate-producing Butyricicoccus), reinforcing intestinal barrier integrity, and thereby suppressing systemic LPS translocation and inflammation. In conclusion, FRQ mitigates alcohol-induced cognitive and hepatic damage via multiple mechanisms, highlighting its promise as an integrative dietary intervention.\n\nID: 42491970\nTitle: Discovery of novel indazole derivatives with anti-neuroinflammatory activity.\nAbstract: This study focuses on the critical role of microglia-mediated neuroinflammation in various neurological disorders. Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.\n\nID: 42491696\nTitle: Microglia and its P2RY12 receptors regulate seizure severity.\nAbstract: Microglia are possible regulators of seizures but previous employed approaches are insufficiently selective of microglial-specific manipulations. To more definitely determine microglial roles in seizure severity, we used the microglial-deficient Csf1r \u0394FIRE/\u0394FIRE mouse model where mice lack microglia but retain brain border-associated macrophages. Using two experimental paradigms, we confirm that a microglial deficiency exacerbates seizures and facilitates the likelihood of developing spontaneous recurrent seizures, indicating that microglia constrain seizure activity. To gain insights into microglial molecular regulators of seizure severity, we examined P2RY12 contributions and demonstrate that a loss of P2RY12 increased seizure severity in both global and microglial-specific knockout mice indicating that microglia suppress seizure severity. During seizures, P2RY12-deficient microglia displayed altered process complexity, accompanied by increased neuronal activation and reduced inhibitory tone. These results link impaired microglial responses to heightened seizure susceptibility and network excitability. Together, we establish microglia and P2RY12 signaling as protective regulators of seizure activity.\n\nID: 42491669\nTitle: Mapping human microglial morphological diversity via handcrafted and deep learning-derived image features.\nAbstract: Microglia regulate brain health and disease through diverse, dynamic activation states, but capturing this continuous heterogeneity at scale remains challenging. We developed an imaging and analysis framework to map activation landscapes of human iPSC-derived microglia (iMG) at single-cell resolution. High-content imaging combined a hypothesis-driven immunofluorescence (IF) panel targeting NF-\u03baB, ASC, and CD45 with a discovery-oriented cell painting (CP) assay. Phenotypes were quantified using handcrafted and representation-learning features. To classify cells, we applied Gaussian mixture models (GMMs), enabling soft probabilistic assignments that capture transitional states. Compared with graph-based methods such as Leiden, GMMs achieved similar performance while providing more interpretable descriptions of microglial heterogeneity. Deep-learning features from the targeted IF panel were most informative, yielding high classification accuracy and strong correlation with biological readouts, including NLRP3 inflammasome activation. This platform offers a scalable approach to quantify microglial states and provides a scalable platform for discovering compounds that modulate microglial phenotypes.\n\nID: 42491545\nTitle: Metabolic remodeling of endometriosis microenvironment: Energy stress and immune evasion.\nAbstract: Endometriosis (EMs) is an estrogen-dependent chronic inflammatory gynecological disease characterized by ectopic growth of endometrial tissues, leading to dysmenorrhea, pelvic pain, and infertility. Although the retrograde menstruation theory clarifies the dissemination of endometrial fragments to ectopic sites, the mechanisms behind the survival of ectopic lesions and their immune evasion in hostile microenvironments remain unclear. Endometrial stromal cells (ESCs) are chronically exposed to a microenvironment of hypoxia, nutrient deprivation and oxidative stress, and this energy stress state drives the ESCs to develop adaptive metabolic reprogramming. Through remodeling glucose, lipid, and amino acid metabolic pathways, ESCs not only fulfill their own proliferative requirements but also utilize metabolites as signaling mediators to modulate immune cell functions. This review elaborates on the characteristics of energy stress-driven metabolic reprogramming in EMs, deciphers its mechanisms underlying immune evasion, and discusses the therapeutic potential of combined metabolic-immune intervention strategies.\n\nID: 42491242\nTitle: Reconstructing the glioblastoma microenvironment in heterotypic 3D spheroids: a multicellular model to study tumor-stromal crosstalk.\nAbstract: The complex interplay between tumor cells and the stromal components of the glioma microenvironment necessitates the development of sophisticated in vitro models capable of modelling key aspects of cellular interactions that occur beyond the limitations of conventional monocultures. The development and characterization of homo- and heterotypic 3D spheroid models incorporating CCF-STTG1 astrocytes, HMC3 microglia, and U87MG glioma cells was undertaken. The assessment of morphological, molecular, and functional properties was performed via flow cytometry, cytokine arrays, ECM analysis and invasion assays (Matrigel\u2122/gelatin). Heterotypic spheroids have been observed to spontaneously self-assemble into a spatially polarized architecture, with microglia and glioma cells segregating into distinct compartments, a pattern suggestive of the cellular topology at the invasive front. The morphological, molecular, and functional properties of the generated 3D models recapitulated several established features associated with in vivo tumors, including growth, invasion, resistance to chemotherapy, and metabolic reprogramming alongside the expression of stemness markers, and key pro-invasive mediators (MMPs, SDF-1\u03b1, VEGF). Secretome profiling revealed a marked, non-additive upregulation of chemokines (IP-10, MIP-1\u03b1) and the emergence of novel correlations (HGF/SDF-1\u03b1, MCP-1/LIF), indicating potential modulation of paracrine networks involved in immune cell trafficking in the heterotypic setting. The initial formation of a rigid ECM matrix appears to be initiated by microglia, while the supply of fibronectin and laminin may be linked to astrocytes exhibiting some features of reactive gliosis, which could help organize invasion pathways. These heterotypic 3D spheroid models offer a stroma-enriched, reproducible platform for the analysis of stromal contributions to glioma progression and for exploratory preclinical evaluation of therapeutic strategies.\n\nID: 42491108\nTitle: Risk warning of systemic immune-inflammation index and coagulation parameters for hospital-acquired pneumonia in patients with traumatic brain injury.\nAbstract: To evaluate the predictive value of a thromboinflammatory signature integrating the Systemic Immune-Inflammation Index (SII) and routine coagulation markers for Hospital-Acquired Pneumonia (HAP) in patients with Traumatic Brain Injury (TBI). This retrospective study included two cohorts of patients with imaging-confirmed TBI: a development cohort (n=204) and an external validation cohort (n=80). Candidate predictors included demographic characteristics, Glasgow Coma Scale score, mechanical ventilation (MV), SII, and all routine coagulation markers, including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen (FIB), and thrombin time (TT). Multivariable logistic regression was used to identify factors associated with HAP. Among patients who developed HAP, ventilator-associated pneumonia (VAP) was analyzed descriptively as an exploratory subgroup only. In the development cohort, 76 of 204 patients (37.3%) developed HAP. Patients with HAP exhibited significant coagulation abnormalities, including elevated FIB. Multivariable logistic regression with collinearity diagnostics (VIF analysis) identified SII, FIB, and MV as independent predictors. The combined model demonstrated good discrimination (AUC=0.824) and maintained moderate performance in the external validation cohort (AUC=0.675). Admission SII, FIB, and MV are independently associated with HAP in patients with TBI. A combined model based on these variables retained original discrimination and nomogram performance for HAP. VAP-related observations are presented only as exploratory subgroup findings.\n\nID: 42491031\nTitle: Correlation between perioperative red blood cell transfusion strategy and 3-month neurological outcomes in patients undergoing craniotomy for traumatic brain injury.\nAbstract: To investigate the correlation between perioperative red blood cell (RBC) transfusion trigger thresholds and 3-month neurological outcomes in patients undergoing craniotomy for traumatic brain injury (TBI). A total of 113 patients were retrospectively enrolled and stratified into two groups according to hemoglobin (Hb) level: a restrictive transfusion group (Hb < 80 g/L) and an liberal transfusion group (Hb < 90 g/L). Transfusion exposure and clinical outcomes were compared between the two groups, and multivariate logistic regression as well as inverse probability of treatment weighting (IPTW) were adopted for statistical analysis. The restrictive group had lower transfusion rate and transfusion volume (both P < 0.05). The incidence of adverse neurological functional outcomes (defined as Glasgow Outcome Scale-Extended score, GOSE score \u2264 4) at 3 months postoperatively was lower in the restrictive group. Multivariate logistic regression analysis indicated that the restrictive transfusion strategy was marginally associated with a lower risk of adverse outcomes (OR=0.40, P=0.053). The IPTW analysis yielded a consistent trend without statistical significance (P=0.110). There was no statistically significant difference in the incidence of complications. The restrictive transfusion strategy can reduce transfusion exposure and is correlated with a favorable trend in neurological functional prognosis. Further studies are still required to validate these findings.\n\nID: 42491014\nTitle: Mechanism of HIF-1\u03b1-mediated angiogenesis in rheumatoid arthritis and progress of natural medicine interventions.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by hyperplasia of synovial pannus and progressive joint destruction. Pathological angiogenesis, driven by hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1), constitutes a core pathological mechanism and has become a critical therapeutic target for RA. This article systematically elucidates the molecular mechanisms by which HIF-1\u03b1 drives pathological angiogenesis through interactions with signaling pathways such as vascular endothelial growth factor (VEGF), angiogenin (ANG)-1/2, CXC chemokine ligand 12 (CXCL12)/CXC chemokine receptor 4 (CXCR4), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR). HIF-1\u03b1-mediated angiogenesis forms a positive feedback network with pathological processes including synovial inflammatory response, glycolytic metabolic reprogramming, and oxidative stress-mitochondrial damage, collectively promoting synovial pannus formation. Additionally, this article summarizes the effects of traditional Chinese medicine formulations and plant-derived monomeric metabolites on HIF-1\u03b1-mediated RA synovial angiogenesis, as well as the preclinical research advances of anti-angiogenic mechanisms. It also briefly explores the potential of novel botanical drugs delivery systems in enhancing the targeting of natural products to the HIF-1\u03b1 pathway and improving therapeutic efficacy, aiming to provide new perspectives and strategic options for HIF-1\u03b1-targeted RA therapies.\n\nID: 42490949\nTitle: High-altitude hypoxic cues and cerebral ischemic tolerance: an evidence-graded translational framework for stroke research.\nAbstract: High altitude exposes the brain to heterogeneous hypoxic, hemodynamic, rheological, inflammatory, and healthcare-access conditions. This heterogeneity makes altitude biologically informative for stroke research, but it does not justify treating natural altitude exposure as a single protective or harmful state. In this structured narrative review, we searched and organized the literature to ask which altitude-associated hypoxic cues resemble or reveal mechanisms compatible with cerebral ischemic tolerance, and what level of evidence supports that claim. We separate long-term adaptation, short-term acclimatization, chronic or excessive environmental hypoxia, and experimental hypoxic conditioning; define direct, supportive, and indirect evidence tiers; and integrate neurovascular-unit biology with multi-omics and stroke pathophysiology. Experimental hypoxic preconditioning remains the clearest direct evidence that a defined sublethal hypoxic stimulus can induce a time-limited tolerant state. In contrast, human high-altitude epidemiology, physiology, and genetics mainly constrain the clinical context and nominate candidate pathways rather than prove stroke-specific protection. We also emphasize that chronic hypoxia can be maladaptive through endothelial dysfunction, oxidative stress, erythrocytosis, thrombogenicity, blood-brain barrier impairment, and microvascular injury. Across neurovascular-unit cell types, a transparent evidence-weighting framework prioritizes endothelial biology because of its direct connection to BBB stability, effective reperfusion, hemorrhagic transformation risk, and no-reflow, while neurons, astrocytes, microglia, oligodendrocyte-lineage cells, and pericytes require different degrees of causal and human validation. We argue that the most productive path forward is not to label altitude as protective, but to use altitude-related biology to prioritize testable, stroke-facing hypotheses regarding BBB stability, microvascular patency, metabolic support, inflammatory thresholds, white-matter resilience, and biomarker-defined conditioning windows.\n\nID: 42490919\nTitle: Meta-analysis of factors affecting hyponatremia after spinal cord injury.\nAbstract: To systematically evaluate the risk factors for hyponatremia in patients with spinal cord injury (SCI) through a meta-analysis, and to provide evidence-based guidance for early identification of high-risk populations and the development of preventive strategies in clinical practice. Electronic databases including China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, Chinese Biomedical Literature Database (CBM), PubMed, and Web of Science were searched from their inception to November 10, 2024. Literature screening, data extraction, and quality assessment were independently conducted by two researchers. The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of the included studies. Meta-analysis was performed using RevMan 5.3 software. A total of 14 studies involving 2,729 patients with SCI were included, among whom 1,160 patients developed hyponatremia and 1,569 had normal serum sodium levels. The NOS scores of the included studies ranged from 7 to 8, indicating generally high methodological quality. Meta-analysis results showed that high-level spinal cord injury (OR\u202f=\u202f1.71, 95% CI: 1.04-2.81), complete spinal cord injury (OR\u202f=\u202f4.96, 95% CI: 3.75-6.57), concomitant traumatic brain injury (OR\u202f=\u202f2.70, 95% CI: 1.79-4.07), and the use of assisted ventilation (OR\u202f=\u202f3.28, 95% CI: 1.52-7.09) were significant risk factors for hyponatremia in patients with SCI (p <\u202f0.05). A funnel plot based on complete spinal cord injury was not completely symmetrical, suggesting a potential risk of publication bias. Current evidence indicates that high-level spinal cord injury (\u2264C4), complete spinal cord injury, concomitant craniocerebral injury, and the use of assisted ventilation are significant risk factors for hyponatremia in patients with SCI. Enhanced monitoring and management of these high-risk populations are recommended to facilitate early identification and timely intervention for hyponatremia. The systematic review was registered in PROSPERO (Unique Identifier: CRDCRD42024585004).\n\nID: 42490781\nTitle: Long-term functional outcomes after unilateral versus bilateral decompressive craniectomy-a single center experience.\nAbstract: Early initiation of neurological rehabilitation following stroke or traumatic brain injury requires access to ventilation and comprehensive care at neurorehabilitation centers. The recovery after decompressive craniectomy (DC) is very heterogeneous and influenced by surgical laterality and complications. This study compared long-term outcomes after unilateral (UDC) versus bilateral DC (BDC). Patients admitted to our neurological rehabilitation center between 2000 and 2018 after BDC were matched by age, sex, and etiology to UDC. Clinical data included initial Glasgow Coma Scale, intracranial lesions, hospital admission time, complications, outcome, ventriculoperitoneal shunts and time to cranioplasty. Functional outcomes were assessed using the Extended Glasgow Outcome Scale (GOSE), Barthel Index (BI), and Early Rehabilitation Barthel Index (eBI) at discharge and follow-up. Follow-up interviews were conducted with 28 patients (15 UDC, 13 BDC) to evaluate GOSE, BI, quality of life, and home circumstances. Fifty patients (mean age 28.2 \u00b1 13\u202fyears; 28% female) were analyzed. Favorable outcomes occurred in 36% of UDC patients versus 16% of BDC patients, while unfavorable outcomes were more frequent in BDC (44% vs. 24%). UDC patients demonstrated significantly better eBI scores at discharge and follow-up (p =\u202f0.043; p =\u202f0.016) and superior GOSE outcomes (p =\u202f0.011). Shorter hospitalization correlated with favorable outcomes in UDC (p =\u202f0.012; r =\u202f-0.628). BDC patients experienced more neurological complications, which were associated with poorer outcomes (GOSE follow-up p =\u202f0.019; r =\u202f-0.411; BI follow-up p =\u202f0.022; r\u202f=\u202f0.415). BDC is associated with poorer functional outcomes and higher complication rates compared to UDC. Further randomized studies are needed to confirm these findings.\n\nID: 42490679\nTitle: Platelet membrane biomimetic nanoparticle-based targeted delivery system of simvastatin for the treatment of ischemic stroke.\nAbstract: Blood-brain barrier (BBB) disruption and excessive neuroinflammation are pivotal drivers of cerebral ischemia-reperfusion injury. Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke.\n\nID: 42490621\nTitle: Cone photoreceptor ablation in microglia-deficient larval zebrafish retina elicits a regenerative response alongside a compensatory immune cell response.\nAbstract: Emerging evidence implicates retinal microglia and inflammation as important components impacting the outcome of retinal regeneration, which is spontaneously achieved in zebrafish retina following acute damage but is limited or blocked in mammals. Here we describe the regenerative response in the larval zebrafish retina following ablation of cone photoreceptors. To investigate the role of microglia in the regenerative response, we used irf8st95 heterozygote (microglia-sufficient) and irf8st95 homozygous mutant (microglia-deficient) zebrafish. We compared multiple aspects of the regenerative response in irf8\u2009+\u2009/- and irf8-/- larval retinas, including entry of the M\u00fcller glia (MG) into the cell cycle, the amplification of MG-derived progenitor cell (MGPC) proliferation, inflammatory and glial reactivity-associated gene expression, and the regeneration of cones. We found only modest impacts to early and late stages of MGPC proliferation and to inflammatory gene expression in irf8 mutants, with no obvious impacts to the regeneration of cones. Notably, we detected a population of immune cells in irf8 mutants that emerged following cone ablation, which expanded in number then were reduced over time, following a trajectory similar to microglia-sufficient siblings but at markedly reduced abundance. The immune cells detected in irf8 mutants included a subset with L-plastin/4C4 antibody staining patterns different than those in microglia-sufficient siblings, suggesting distinct origins and/or phenotype compared to resident microglia in controls. The presence of immune cells in irf8 mutants following cone ablation limited our ability to make strong conclusions about the role of microglia in regeneration of cones. However, our results are consistent with several reports that indicate a role for microglia in regulating MGPC proliferation in the regenerating retina. Collectively considered with other reports, our results further indicate that compensatory responses, which may include different immune cells and/or signaling from other retinal cell types such as M\u00fcller glia, may be elicited in microglia-deficient retinas upon neuronal damage.\n\nID: 42490474\nTitle: Epigenetic and 3D genome reprogramming during the aging of the human hippocampus.\nAbstract: Changes in gene expression have been observed in the aging human brain, but our understanding of the underlying regulatory mechanisms remains limited. To unravel these complexities, we analyzed single-nucleus gene expression, chromatin accessibility, DNA methylation, and three-dimensional (3D) chromatin architecture from human hippocampal tissues spanning the adult lifespan. We identified both linear and nonlinear dynamic gene regulatory programs during aging. Between the ages of 50 to 75, embryonic yolk sac-derived microglia were depleted and replaced by cells resembling peripheral blood monocyte-derived microglia. Hippocampal astrocytes decreased substantially with age, including those regulating synaptic transmission. Across cell types, 3D genome architecture underwent global erosion. Our analysis provides insights for how altered gene regulatory programs promote cell type-specific aging phenotypes in the human brain.\n\nID: 42490223\nTitle: Protocol for studying Chemerin 15-enhanced microglial phagocytosis in cerebral ischemia-reperfusion injury via the ChemR23/p38 MAPK pathway.\nAbstract: Chemerin 15 (C15), a chemerin-derived peptide, enhances microglial phagocytosis through the ChemR23/p38 MAPK pathway to alleviate brain damage after cerebral ischemia-reperfusion (I/R) injury. Here, we present a protocol for studying C15-enhanced microglial phagocytosis in cerebral I/R injury via the ChemR23/p38 MAPK pathway. We describe steps for establishing in vivo and in vitro models, detecting microglial phagocytic activity, verifying the underlying signaling pathway, and evaluating therapeutic effects. We detail procedures for model construction, functional detection, molecular mechanism verification, and outcome assessment. For complete details on the use and execution of this protocol, please refer to Yang et al.1.\n\nID: 42489971\nTitle: Glymphatic Dysfunction and Aquaporin-4 Dysregulation in Traumatic Brain Injury and Brain Tumors: A Review.\nAbstract: The glymphatic system is a cerebrospinal fluid-interstitial fluid exchange pathway that clears metabolic waste and maintains brain fluid homeostasis. Aquaporin-4 (AQP4), a water channel at astrocytic endfeet along the neurovascular interface, supports perivascular water transport and glymphatic flow. Disruption of this glymphatic-AQP4 unit is implicated in conditions with altered fluid dynamics, including traumatic brain injury (TBI) and brain tumors. We reviewed experimental and clinical studies examining glymphatic pathways and AQP4 regulation in TBI and brain tumors, and synthesized evidence on glymphatic physiology, AQP4 polarization, and imaging-based assessment to compare mechanisms of disruption in injury versus tumor remodeling. Evidence shows reduced glymphatic transport in both conditions, commonly accompanied by altered AQP4 localization. In TBI, mechanical injury triggers astrocytic reactivity, blood-brain barrier disruption, and loss of perivascular AQP4 polarization, impairing clearance across phases of injury. In brain tumors, parenchymal remodeling, vascular compression, and vasogenic edema disrupt cerebrospinal fluid dynamics and glymphatic pathways. Across disease states, total AQP4 expression alone poorly predicts glymphatic function; instead, spatial localization and polarization of AQP4 at astrocytic endfeet more consistently correlate with clearance efficiency. Emerging imaging approaches, including diffusion-based MRI metrics and perivascular space quantification, offer potential noninvasive methods for assessing glymphatic alterations in vivo, although their reliability and biological specificity remain debated and under active investigation. Overall, the glymphatic-AQP4 system is a key neurovascular interface regulating brain fluid balance. Disrupted AQP4 polarization and glymphatic transport contribute to edema and impaired solute clearance in both TBI and brain tumors. Future work should prioritize standardized imaging biomarkers and time-dependent strategies to restore glymphatic function and perivascular AQP4 organization.\n\nID: 42489761\nTitle: Lipoprotein(a) -Related Cognitive Vulnerability After Stroke Beyond High-Sensitivity C-Reactive Protein.\nAbstract: Post-stroke cognitive impairment (PSCI) reflects vulnerability to cognitive decline beyond acute brain injury. Lipoprotein(a) (Lp(a)) is a genetically determined vascular risk factor with pro-inflammatory and pro-atherogenic properties, but the pathways linking Lp(a) to cognitive outcomes after stroke remain unclear. We examined whether systemic inflammation mediates or modifies Lp(a)-related cognitive risk after ischemic stroke.\u00a0We analyzed data from a prespecified substudy of the Third China National Stroke Registry. Baseline serum Lp(a) and high-sensitivity C-reactive protein (hs-CRP) were measured. PSCI was defined as a Montreal Cognitive Assessment score\u2009\u2264\u200922 at 1 year. Multivariable logistic regression, interaction, joint exposure, and causal mediation analyses were performed to evaluate the role of systemic inflammation in the Lp(a)-PSCI association.\u00a0Among 954 patients with acute ischemic stroke, higher baseline Lp(a) was associated with increased PSCI risk after adjustment for baseline cognitive performance and clinical covariates (highest vs. lowest tertile: OR, 1.479; 95% CI, 1.007-2.170). In contrast, hs-CRP was not independently associated with PSCI after multivariable adjustment. No significant multiplicative interaction between Lp(a) and hs-CRP was observed (P\u2009=\u20090.2026). Although joint exposure analyses showed the highest PSCI risk among patients with both elevated Lp(a) and hs-CRP, mediation analysis did not support hs-CRP as a meaningful mediator (proportion mediated\u2009=\u20091.46%). These findings suggest that the observed association between Lp(a) and PSCI was not substantially explained by hs-CRP-indexed peripheral systemic inflammation.\u00a0Elevated Lp(a) was associated with PSCI independently of baseline cognitive performance, but this association was not mediated or significantly modified by hs-CRP. Lp(a)-related cognitive vulnerability after ischemic stroke may therefore reflect vascular susceptibility not captured by hs-CRP alone, with hs-CRP-defined systemic inflammation contributing to cumulative risk rather than serving as the primary mechanistic pathway.\n\nID: 42489732\nTitle: Acute-on-chronic versus isolated acute subdural hematoma in complicated mild traumatic brain injury: association with radiological mass effect markers in a multicenter cohort.\nAbstract: The clinical impact of acute-on-chronic subdural hematoma (acSDH) in mild traumatic brain injury (mTBI) remains incompletely characterized. We assessed whether acSDH, compared with isolated acute SDH (aSDH), is associated with worse neurological presentation and increased radiological markers of mass effect. We conducted a retrospective multicenter cohort study using the IMADIS teleradiology head trauma workflow (103 emergency departments in France, January 2020 to December 2022). Adult patients with complicated mTBI (i.e., GCS 13-15 plus intracranial hemorrhage or skull fracture) and acute SDH on non-contrast head CT were eligible. Exposure was acSDH versus aSDH based on structured radiology reports. Outcomes were (1) GCS\u2009<\u200915 at presentation, (2) SDH maximal thickness\u2009\u2265\u20097\u00a0mm, (3) radiological brain herniation, and (4) intermediate or high QueBIC risk category. Univariable and multivariable logistic regression models were used to estimate associations. Among 935 included patients, 107 (11.4%) had acSDH. Patients with acSDH were older (\u2265\u200975 years: 57.0% vs. 39.7%, p\u2009<\u2009.0001) and more frequently had dementia (8.4% vs. 3.7%, p\u2009=\u2009.0465). Compared with aSDH, acSDH was associated with GCS\u2009<\u200915 (37.4% vs. 21.7%, P\u2009=\u2009.0010) and confusion (41.0% vs. 25.8%, p\u2009=\u2009.0016). On CT, acSDH was associated with SDH thickness\u2009\u2265\u20097\u00a0mm (54.2% vs. 20.4%, OR 4.50, 95%CI 2.90 to 7.01) and brain herniation (27.1% vs. 10.7%, OR 3.61, 95%CI 2.20 to 5.85). AcSDH was independently associated with intermediate or high QueBIC category (OR 3.38, 95%CI 1.95 to 6.27) and with the other severity markers. In complicated mTBI with acute SDH, acSDH is associated with worse neurological presentation and substantially higher radiological markers of mass effect, as well as a higher QueBIC risk category. These findings support considering acSDH as a high-risk imaging phenotype that may warrant closer early monitoring and timely neurosurgical discussion. Future studies should evaluate associations with patient-centered clinical outcomes and neurosurgical interventions. This retrospective, observational, multicenter study was approved by the French National Radiological Review Board (CRM-2507-489, on 16 July 2025).\n\nID: 42489586\nTitle: Efficacy of combined transcranial direct current stimulation and computer-based cognitive rehabilitation on cognition in patients with traumatic brain injury: A systematic review.\nAbstract: Patients with traumatic brain injury (TBI) frequently experience cognitive deficits. Transcranial direct current stimulation (tDCS) and computer-based cognitive rehabilitation (CBCR) have been used in cognitive rehabilitation patients with TBI. This review aims to explore the effects of integrating tDCS and CBCR on cognition post-TBI. \"PsycINFO, PubMed, EMBASE, MEDLINE, SCOPUS, Web of Science, PEDro, and CINAHL\" were explored until March 2026. Randomized studies that integrated tDCS and CBCR and included at least one outcome measure evaluating cognitive function in patients with TBI were included. The Cochrane Risk of Bias 2 (RoB 2) instrument was employed to assess the risk of bias. Four studies involving 115 participants met the inclusion criteria. Two studies reported significant improvements in executive function and working memory after combining tDCS and CBCR compared with no-intervention controls. The other two studies found no significant differences between groups in memory, attention, or executive function outcomes after combining tDCS and CBCR compared with combining tDCS and CBCR. Overall, evidence on the effects of combining tDCS and CBCR is limited. Additional high-quality studies with consistent treatment protocols and long-term follow-up are strongly warranted to understand the effects of the intervention on cognition in individuals with TBI.\n\nID: 42489527\nTitle: Elevated ferritin expression in microglia and extracellular amyloid-\u03b2 deposition are associated with reduced neurofibrillary degeneration in human isocortex, but not allocortex.\nAbstract: BackgroundPrior work in preclinical late-onset Alzheimer's disease (LOAD) focused on neuritic plaque development suggested that intracellular ferritin expression in microglia and extracellular deposition of amyloid-\u03b2 (A\u03b2) are innate neuroprotective mechanisms geared specifically towards limiting aging-dependent increases in intracerebral free iron which likely contribute to development of neurofibrillary degeneration (NFD).ObjectiveImprove understanding of LOAD pathogenesis.MethodsImmunohistochemical comparison of the extent of NFD with the intensity of ferritin expression and A\u03b2 deposition in three brain regions, including temporal lobe (entorhinal cortex, hippocampus), frontal, and occipital cortex in 34 non-demented human subjects at Braak stages II-III.ResultsFerritin-positive microglia are present with similar quantity and intensity in the allo- and isocortices of every individual in the cohort. Extracellular A\u03b2 deposition in the isocortex is observed before substantial NFD develops, but in the allocortex (temporal lobe) there are no A\u03b2 deposits in 50% of subjects despite extensive NFD. Cytoskeletal lesions in the allocortex consist of atrophic grid cells, abundant pretangles, neuropil threads, neurofibrillary tangles, and neuritic plaques; isocortical sites show either no NFD at all or only minimal NFD presenting as solitary pretangles or tangles, neuropil threads, or droplet degeneration spheres from ferroptotic neurons. Presence of degenerating grid neurons in entorhinal cortex coincides with microglial apoptosis.ConclusionsNeuroprotection via ferritin expression and A\u03b2 deposition is more effective in the isocortex than in allocortex. Findings support the hypothesis that degeneration or death of neuroprotective microglia promotes neuronal degeneration.\n\nID: 42489526\nTitle: Tablet-based cognitive self-assessment: English translation of Cog-First app.\nAbstract: Acquired brain injuries (ABI) frequently lead to cognitive impairments, which can be challenging to detect and persist for years, negatively impacting patient outcomes. Timely and specific screening is crucial for proper management. Cog-First is a tablet-based self-assessment of executive functions, memory, and attention lasting approximately 20 min. This study aimed to develop the English version of Cog-First and evaluate its feasibility. A two-phase study was conducted. Phase 1 involved a rigorous translation and cultural adaptation process, following established guidelines. Phase 2 consisted of an exploratory comparison between MoCA and Cog-First scores in individuals with ABI. The English version of Cog-First was developed. Practitioners highly rated the relevance and applicability. Strong agreement (90%) was observed for memory, attention and inhibition sub-tests. About 90% of ABI participants expressed a high level of satisfaction. Exploratory analyses showed an association between MoCA and Cog-First scores (p\u2009=\u20090.037, r\u2009=\u2009.46). This study successfully translated and culturally adapted Cog-First into English and demonstrated its feasibility and acceptability in English-speaking individuals with ABI. While further research is required to explore its psychometric properties, normative values and clinical utility comprehensively, Cog-First might enhance the detection of subtle cognitive deficits and inform targeted rehabilitation strategies.\n\nID: 42489420\nTitle: Psychological flexibility or inflexibility: examining the distinct roles of these transdiagnostic factors in mild traumatic brain injury recovery.\nAbstract: Psychological flexibility (PF) and psychological inflexibility (PI) are transdiagnostic processes implicated in mental health outcomes, yet their distinct roles in mild traumatic brain injury (mTBI) recovery remain unclear. This study examined PF and PI in a treatment-seeking mTBI sample and tested whether these processes operate through distinct pathways linking post-concussion symptoms (PCS), functional disability, and psychological distress. Participants were 173 adults with mTBI recruited from outpatient concussion rehabilitation services in New Zealand. Participants completed measures of PCS (Rivermead Postconcussion Symptom Questionnaire), disability (WHODAS-12), psychological distress (DASS-21), PI (reactive avoidance; AAQ-ABI), and PF (Personalized Psychological Flexibility Index; PPFI). Structural equation modeling tested a parallel mediation model in which PCS and disability predicted distress indirectly via PI and PF. Three models were estimated, substituting PPFI facets (behavioral engagement, acceptance, harnessing). Across the three structural equation models, overall model fit was adequate, with the behavioral engagement model demonstrating excellent fit. Higher reactive avoidance was consistently associated with greater psychological distress, and a history of a mental health conditions, across all models. Reactive avoidance mediated the relationship between PCS and distress in the behavioral engagement and harnessing models. Behavioral engagement and acceptance were each independently associated with lower psychological distress, whereas harnessing showed a small positive association with distress. These facets did not mediate the relationship between PCS and psychological distress. No serial mediation effects between reactive avoidance and PF on psychological distress were observed. This study demonstrates that PF and PI represent related but distinct transdiagnostic processes shaping psychological outcomes following mTBI. Reactive avoidance emerged as a key mechanism linking PCS to psychological distress, while behavioral engagement and acceptance were independently associated with lower distress. By delineating these processes, the findings extend existing mTBI research and offer clinically relevant insights with the potential to inform transdiagnostic psychological interventions.\n\nID: 42489413\nTitle: Helmet Use, Clinical Outcomes, and Short-Term Direct Cost After Repeal of Nebraska's Universal Motorcycle Helmet Law.\nAbstract: On January 1, 2024, Nebraska repealed its universal motorcycle helmet law for riders aged \u226521 years with a valid Class M license. We evaluated changes in helmet use, clinical outcomes, and short-term direct institutional costs following repeal. In this multicenter retrospective cohort study, motorcycle crash patients treated at five ACS-verified Level I-III trauma centers in eastern Nebraska before and after repeal were compared by law era and helmet status. Helmet-use trends were assessed using segmented binomial logistic regression. Cost analyses were restricted to patients with positive direct institutional costs using survivor-only and log-transformed models. Among 467 patients (241 pre-repeal, 226 post-repeal), helmet use declined from 84.2% to 20.4% after repeal (p<0.001). Segmented regression demonstrated an immediate reduction in helmet use after repeal (OR 0.17, 95% CI 0.06-0.44; p<0.001), consistent with adjusted individual-level analysis (aOR 0.04, 95% CI 0.03-0.07; p<0.001). Post-repeal, non-helmeted riders had greater unadjusted head-injury burden and more neurosurgical interventions. After adjustment, non-helmeted status remained independently associated with neurosurgical intervention (aOR 3.10, 95% CI 1.03-9.35; p=0.044), but not BIG score \u22652, severe traumatic brain injury composite, or mortality. Adjusted log-transformed analyses showed lower short-term direct institutional costs among non-helmeted riders (cost ratio 0.68, 95% CI 0.54-0.86; p=0.001), likely reflecting differences in injury patterns and procedural utilization rather than reduced economic burden. Nebraska's helmet-law repeal was associated with an immediate and sustained reduction in helmet use. Non-helmeted riders had higher adjusted odds of neurosurgical intervention despite similar adjusted severe brain injury and mortality outcomes. Lower short-term institutional costs should not be interpreted as economic neutrality because they exclude downstream rehabilitation, disability, productivity losses, and societal costs.\n\nID: 42489128\nTitle: Photobiomodulation of immune crosstalk rescues neuroinflammation in Alzheimer's disease models.\nAbstract: Peripheral immune cell infiltration and crosstalk with brain-resident cells critically drive Alzheimer's disease (AD)-associated neuroinflammation, highlighting its therapeutic potential. Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration.\n\nID: 42488972\nTitle: Long-term medical and psychosocial vulnerability after home return following severe traumatic brain injury.\nAbstract: To identify a 5-year medical and psychosocial vulnerability profile among adults living at home 1 year after severe TBI and examine associated early characteristics. Retrospective secondary analysis of a multicentre longitudinal cohort. Adults aged 16 years or older with operationally defined severe traumatic brain injury, private residence at 1 year, linked 5-year follow-up, and complete data for 4 profile indicators. Latent class analysis used 5-year rehospitalization, PHQ-9, GAD-7, and Satisfaction With Life Scale scores dichotomized with prespecified clinically interpretable thresholds. External rehabilitation outcomes and early associated factors were examined descriptively and with multivariable logistic regression. Among 2,835 participants, a 2-class solution identified a lower-vulnerability profile (n\u2009=\u20092,361) and a multidomain vulnerability profile (n\u2009=\u2009474). The latter showed more depressive symptoms, anxiety symptoms, low life satisfaction, and rehospitalization, with poorer 5-year functioning, participation, health, productive status, and higher frequency of non-private residence. Better 1-year global outcome was protective; female sex, preinjury illicit drug use, and living alone at 1 year were associated with assignment to this profile. Home return after severe traumatic brain injury should be treated as a transition point for longitudinal rehabilitation surveillance.\n\nID: 42488958\nTitle: BCKDK, A Novel Hypoxia-Responsive Kinase That Exacerbates Cerebral Ischemia Injury.\nAbstract: Alterations in circulating amino acid profiles have been observed in ischemic stroke patients; however, whether cerebral ischemia disrupts amino acid metabolism within brain tissue and whether this disruption contributes to cellular stress and cerebral injury remain unknown. This hypothesis-testing study investigates disrupted BCAA (branched-chain amino acid) catabolism as a key mechanism of ischemic brain damage and evaluates BCKDK (branched-chain \u03b1-keto acid dehydrogenase kinase) as a novel therapeutic target. Mouse primary cortical neurons subjected to oxygen-glucose deprivation and brain tissue from a mouse acute ischemic stroke model were used as experimental systems. Untargeted metabolomics and metabolic flux analysis were used to characterize BCAA metabolism in both models. In vivo pharmacological inhibition or in vitro knockdown of BCKDK was performed using BT2 treatment or RNA interference. Primary outcome variables included infarct volume, BCKDH (branched-chain \u03b1-keto acid dehydrogenase) enzyme activity, neuronal viability, and markers of energy metabolism and glutamate excitotoxicity. Between-group differences were evaluated using 1-way ANOVA; data are presented as mean \u00b1 SD with 95% CIs and corresponding P values. Metabolomics analysis of oxygen-glucose deprivation-exposed primary neurons revealed impaired BCAA catabolism and significant BCAA accumulation compared with normoxic controls. In ischemic mouse brain tissue, BCKDH activity was significantly suppressed, and BCKDK expression was markedly upregulated relative to sham-operated animals. Both pharmacological and genetic suppression of BCKDK substantially reduced cerebral ischemic injury, as evidenced by decreased infarct volume and improved neuronal survival (95% CI and P values per comparison). Mechanistically, ischemia-induced BCKDK expression via HIF-1\u03b1 (hypoxia-inducible factor 1\u03b1)-mediated transcriptional activation, which inhibited BCAA conversion to tricarboxylic acid cycle substrates, thereby potentiating energy deficiency and glutamate excitotoxicity. These data identify BCKDK as a novel hypoxia-responsive factor whose upregulation drives disrupted BCAA catabolism as a key mechanism of ischemic neuronal injury. BCKDK represents a promising therapeutic target for cerebral ischemia, directly supported by both in vitro and in vivo experimental evidence presented here.\n\nID: 42488868\nTitle: Predicting Clinically Significant Brain Injuries Following Mild TBI: A Comparative Study of Canadian CT Head Rule and New Orleans Criteria at a National Trauma Centre.\nAbstract: Mild traumatic brain injury (mTBI) is one of the most common injuries treated at any trauma centre. Whereas the general use of CT for all patients with mTBI is inefficient and wasteful, the omission of a clinically important brain injury is not desirable. Several guidelines have been developed to assist physicians in determining who actually needs a head CT. For this reason, the Canadian CT Head Rule (CCHR) and the New Orleans Criteria (NOC) were compared in this study on their efficacy in predicting surgically significant brain injuries and the need for neurosurgical intervention. The research was a prospective cross-sectional study at a level 1 trauma centre that received ethical approval from the Hospital. Consenting adult patients who presented with mild TBI within 24 hours were recruited. They were assessed with the NOC and CCHR, whose decisions were compared with each other and with CT head findings. A total of 103 patients were successfully enrolled, males were 91 and females were 12, with a mean age of 32.48\u00b112.27 years old. The NOC guideline had a sensitivity (88.6%), specificity (21.4%), positive predictive value (47.0%) and negative predictive value (70.6%) of clinically significant brain injury; while CCHR guideline showed sensitivity (86.4%), specificity (30.4%), positive predictive value (49.4%) and negative predictive value (73.9%) of clinically significant brain injury (table 3), however, statistically were not significantly different with P-value of 0.39. Similarly, there was no statistically significant difference between the two guidelines for the need for neurosurgical intervention, as the P-value was 0.48. Following the findings, this study suggests that either NOC or CCHR is safe to be used for ordering a head CT for patients with mild TBI.\n\nID: 42488855\nTitle: Opioid Addiction Medicine in Nigeria: Bridging Clinical Gaps in a Silent Epidemic-A Narrative Review.\nAbstract: Opioid use disorder (OUD) is an emerging public-health challenge in Nigeria, driven largely by non-medical use of tramadol and codeine and compounded by limited access to evidence-based care. This narrative review synthesises evidence on the epidemiology, patterns, harms and treatment gaps for OUD in Nigeria and identifies priorities for policy and research. We searched PubMed/MEDLINE, Embase, PsycINFO, the Cochrane Library, African Journals Online, Google Scholar and grey literature from 2005 to 2024 for Nigerian data on non-medical opioid use, clinical harms, opioid agonist therapy (OAT) services, barriers and community supports. Findings were thematically synthesised using Braun and Clarke's framework, with quality appraisal using Joanna Briggs Institute tools and the SANRA scale. Thirty studies were included. The 2019 national drug use survey estimated past-year opioid use at 4.7% (approximately 4.6 million people), with institution-based surveys reporting high lifetime misuse among undergraduates. Reported harms included overdose, seizures, psychiatric comorbidity and injectable pentazocine dependence with severe soft-tissue infections. OAT availability remains highly centralised, with limited community recovery infrastructure. Nigeria's OUD burden is substantial but unevenly characterised, highlighting the need to decentralise OAT, integrate addiction training, strengthen surveillance and expand community supports.\n\nID: 42488755\nTitle: A single mild closed-head injury disrupts synaptic strength and promotes hippocampal hyperexcitability in mice.\nAbstract: Traumatic brain injury can result in persistent cognitive, behavioural, and emotional deficits, with the hippocampus among the most vulnerable circuits after injury. However, how diffuse injury differentially alters hippocampal subregions across time remains incompletely defined. Here, we used a mouse closed-head injury model to characterize early transcriptomics, subacute-to-chronic electrophysiology, dendritic spine morphology, and delayed immunoreactivity for glial fibrillary acidic protein (GFAP), ionized calcium-binding adapter molecule 1 (IBA1), and the pan-leukocyte marker CD45. Bulk RNA sequencing at 9, 24, and 72\u2005h post-injury revealed induction of immediate early genes and neuronal excitability transcripts at 9\u2005h alongside inflammatory pathways. These neuronal signatures diminished by 24-72\u2005h while immune-associated programs persisted. Ex vivo field recordings in CA1 and dentate gyrus at 1, 3, and 6 weeks post-injury revealed reductions in synaptic strength in both regions at 1 week. Dentate gyrus deficits persisted at 3 weeks but recovered by 6 weeks, whereas CA1 showed depression at 1 and 6 weeks with relative sparing at 3 weeks. Fibre volley recruitment was preserved across regions and timepoints, arguing against gross presynaptic loss. Population spike thresholds were reduced in both regions, indicating increased neuronal excitability that persisted in CA1 but partially recovered in dentate gyrus. DiOlistic labelling and spine reconstruction revealed stable total spine density, but spine class composition showed sex-dependent injury effects in CA1 with altered mushroom and stubby proportions in males. Immunohistochemistry across 1-8 weeks post-injury revealed cortical gliosis but no injury-related changes in hippocampal GFAP or IBA1, while CD45 immunoreactivity increased in a delayed, sex-dependent manner within hippocampus. Together, these findings show that a single closed-head injury produces sustained hippocampal circuit dysfunction characterized by reduced synaptic strength and increased neuronal excitability, with region-dependent recovery dynamics, preserved presynaptic recruitment, and delayed hippocampal CD45 increases that do not parallel local glial activation.\n\nID: 42488639\nTitle: Autoimmune signatures in neurodegenerative dementias: from peripheral immune activation to CNS pathology.\nAbstract: Neurodegenerative dementias, including Alzheimer's disease, Parkinson's disease dementia, dementia with Lewy bodies, and related tauopathies, are traditionally defined by protein aggregation, neuronal dysfunction, synaptic loss, and glial-mediated neuroinflammation. However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.\n\nID: 42488574\nTitle: Developmentally sensitive neuropharmacological effects of dexamethasone in neonatal bronchopulmonary dysplasia-associated brain injury via microglial Acod1-itaconate/IL-1\u03b2 signaling.\nAbstract: Bronchopulmonary dysplasia (BPD) in preterm infants is frequently accompanied by neurodevelopmental impairment, yet the central neuropharmacological actions of dexamethasone (DEX), a commonly used therapy for severe or evolving BPD, remain incompletely understood. In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain.\n\nID: 42488567\nTitle: Chinese prescription Kangen-karyu attenuates neuronal damage and improves cognitive function in global cerebral ischemia/reperfusion by regulating ROS-mediated MAPK activation.\nAbstract: Global cerebral ischemia is a well-established experimental model for studying hippocampal vulnerability and memory impairment. This study investigated the neuroprotective potential of Kangen-karyu (KK) in a mouse model of global cerebral ischemia/reperfusion injury induced by bilateral common carotid artery occlusion (BCCAO). Male C57BL/6J mice were subjected to BCCAO followed by reperfusion. KK or nimodipine was administered orally either before or after ischemia. Neurological outcomes, histopathology, and markers of oxidative stress, inflammation, and apoptosis were evaluated. Post-ischemic administration of KK significantly reduced brain edema, neuronal degeneration, and ischemia/reperfusion-induced brain damage, while improving cognitive performance. These effects were associated with decreased phosphorylation of JNK/p38 MAPK and reduced expression of iNOS and apoptosis-related proteins. Post-treatment produced greater benefits than pre-treatment or nimodipine. KK may have therapeutic potential for mitigating global cerebral ischemia/reperfusion-induced brain injury, possibly through modulation of stress- and inflammation-related pathways. Further studies are warranted to validate these findings.\n\nID: 42488555\nTitle: Modeling Alzheimer's disease with brain organoids: mechanisms, applications, and future directions.\nAbstract: Human pluripotent stem cell-derived brain organoids have emerged as a transformative platform for modeling Alzheimer's disease (AD), thus addressing long-standing translational obstacles posed by the disease's complex etiology and interspecies differences. This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications.\n\nID: 42488529\nTitle: Targeting Interleukin-6 Signaling with Reactive-Oxygen-Species-Responsive Hydrogel to Promote Regeneration after Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) triggers an excessive inflammatory response, characterized by the up-regulation of various inflammatory factors that impede neural regeneration and functional recovery. Interleukin-6 (IL-6) is an early and critical inflammatory mediator observed in lesions post-SCI. Antagonizing the signaling pathway presents a promising strategy to mitigate early inflammation and secondary injury after trauma. Here, we identified specific activation of the IL-6 receptor in neurons and microglia in lesions, indicating their responsiveness to early up-regulated IL-6 signaling within the microenvironment. In\u00a0vitro, neutralizing IL-6 signaling in microglia effectively alleviated their inhibitory effects on neuronal axon growth in conditioned media. Building on this, we developed a reactive-oxygen-species-responsive hydrogel for the sustained local delivery of tocilizumab, an IL-6 receptor antagonist, and implanted it in a complete transection SCI model. In\u00a0vivo, sustained IL-6 receptor blockade effectively reduced early inflammatory cell infiltration, modulated microglial polarization toward an anti-inflammatory phenotype, and fostered neuronal regeneration within the lesion. Importantly, this therapeutic intervention promoted long-term hind limb functional recovery in SCI mice. This study underscores the therapeutic potential of precisely targeting early inflammatory cytokine signaling pathways, particularly IL-6, to improve outcomes after SCI.\n\nID: 42488509\nTitle: Evaluating the electrocardiographic abnormalities in traumatic brain injury: prevalence, severity correlation, and outcome prediction.\nAbstract: Traumatic brain injury (TBI) induces systemic responses, including neurogenic cardiac injury via the brain-heart axis, manifesting as electrocardiographic (ECG) abnormalities that may predict outcomes. This systematic review aimed to evaluate the diagnostic and prognostic utility of ECG monitoring in patients with TBI, identify knowledge gaps, and guide future research. Following PRISMA guidelines, we searched PubMed and Google Scholar (January 2020 - March 2025) for studies on adult patients with TBI (\u2265 16 years) who underwent acute ECG assessment (\u2264 72 hours post-injury). The inclusion criteria focused on observational/cohort studies that reported ECG changes, severity correlations, and outcomes. The exclusion criteria were pediatric cases, pre-existing cardiac conditions, and non-English articles. Data were extracted from the eligible studies. Six studies (1,642 patients) revealed ECG abnormalities in 10-88% of cases, increasing with TBI severity (e.g., prolonged QTc in 3% of mild cases vs. 15% of severe cases). Common changes included repolarization issues (QTc prolongation and ST-segment/T-wave alterations), arrhythmias, and conduction disturbances. Abnormalities often resolved within days, improved post-neurosurgery (e.g., reduced QTc), and predicted mortality (e.g., QTc prolongation/ST depression as independent factors) and cardiac dysfunction. ECG changes are prevalent in TBI, correlate with severity, and have prognostic value for risk stratification. Routine monitoring is recommended, and larger, standardized studies are needed to optimize management.\n\nID: 42488470\nTitle: Electrochemical monitoring of early astrocytic responses underlying the synergistic effect of extracellular matrix softening and hypoxia.\nAbstract: Traumatic brain injury (TBI) disrupts central nervous system homeostasis, leading to extracellular matrix (ECM) softening and localized hypoxia and thus contributing to astrocytic activation and sustained neuroinflammation. But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention.\n\nID: 42488391\nTitle: Harmonization of social and physical health measures across prospective clinical studies of combat exposed service members and veterans: the total brain diagnostics program.\nAbstract: Traumatic Brain Injury is prevalent during military service and is associated with short- and long-term psychosocial and functional changes, though comprehensive longitudinal data on Veterans and active-duty service members (SMs) are lacking. To address this research gap, we utilized data from the Long-term Impact of Military-relevant Brain Injury Consortium (LIMBIC) and the Translational Research Center for TBI and Stress Disorders (TRACTS), two prospective longitudinal cohort studies of veterans and active duty SMs, each containing a wide range of symptom scales, objective assessments, and health-related outcomes. This paper describes the innovative methods used to achieve the initial proof-of-concept harmonization for baseline psychosocial and physical health data from these two large cohort studies. To achieve harmonization, we gathered a multidisciplinary team with clinical and research expertise. We created a list of measures utilized by each study and organized them into larger clinically meaningful domains. When possible, we harmonized full measures, or single items directly, while others needed to be indirectly harmonized, by recoding, aligning categorical levels, and categorizing scales based on established cut scores. We calculated descriptive statistics to summarize and compare data. We then conducted Principal Component Analysis (PCA) for all continuous measures to assess whether site-level effects were observed in the shared variance. A total of 73 variables capturing psychosocial function, sensorimotor, pain, and clinical health factors were harmonized across the LIMBIC and TRACTS studies. There were no differences in sex or ethnicity distributions between the studies. Sensory, social health, and health related clinical data were broadly comparable across cohorts, while pain intensity and headache disability were higher in LIMBIC. PCA analysis suggests data is suitable for pooled analysis. We were able to directly harmonize multiple self-report measures of social well-being and indirectly harmonize other functional and demographic variables. While this initial effort focused on baseline data, the included principles can be employed to harmonize longitudinal data to increase the ability to detect clinical phenotypes to be applied in precision medicine approaches in future research.\n\nID: 42488390\nTitle: The effect of concurrent neural injuries on hemorrhage.\nAbstract: Spinal cord injury (SCI) is often accompanied by additional tissue damage (polytrauma) that amplifies inflammation and activates pain pathways. The latter has been studied by engaging nociceptive fibers using electrical stimulation or capsaicin caudal to a thoracic SCI. Nociceptive stimulation 1\u202fday after SCI increases hemorrhage, amplifying secondary tissue loss. Noxious stimulation also promotes hemorrhage after a traumatic brain injury (TBI). A common form of polytrauma after SCI involves a TBI. The current study examines whether a concurrent TBI promotes hemorrhage after SCI. This also allowed us to evaluate whether a concurrent SCI promotes brain hemorrhage after TBI. Animals received a thoracic SCI and a concurrent brain surgery (anesthesia alone, craniectomy, or TBI). Other animals received a TBI to the frontal region and a concurrent spinal surgery (anesthesia alone, laminectomy, or SCI). Tissue was collected 24\u202fh later, sectioned, and the extent of brain/spinal cord hemorrhage was quantified. Sham controls were included to verify a remote injury (SCI/TBI) does not induce hemorrhage in the absence of local neural damage. A concurrent TBI with a SCI amplified hemorrhage in the spinal cord. A craniectomy had an intermediate effect on hemorrhage. Additionally, concurrent SCI with a TBI increased hemorrhage in the brain with a more modest effect. The results provide a link between hemorrhage development and concurrent neural injuries, with greater hemorrhage observed after SCI in animals with a concurrent TBI. SCI modestly impacted hemorrhage after TBI. These results provide a basis to further investigate the mechanisms responsible for interactions between multiple neurotraumatic injuries.\n\nID: 42488223\nTitle: Near-infrared spectroscopy cerebral oximetry in pediatric congenital heart disease with cardiopulmonary bypass: a narrative review of current evidence and neuroprotection.\nAbstract: Children with congenital heart disease (CHD) often require early surgical repair supported by cardiopulmonary bypass (CPB). Although survival has improved, neurological injury and later neurodevelopmental impairment remain common, motivating continuous perioperative neuromonitoring. Near-infrared spectroscopy (NIRS) provides noninvasive, real-time regional cerebral oxygen saturation (rScO2), reflecting the balance between cerebral oxygen delivery and metabolic demand. This review summarizes evidence on NIRS-derived perioperative rScO2 patterns in pediatric CHD surgery with CPB and examines associations between cerebral oxygenation abnormalities, markers of brain injury, and neurodevelopmental outcomes. rScO2 typically increases during cooling/deep hypothermia but reaches nadirs during low-flow perfusion or circulatory arrest and in early rewarming, suggesting vulnerability windows when oxygen supply-demand mismatch is most likely. Definitions and thresholds for cerebral desaturation vary substantially across studies, yet accumulating data indicate that postoperative cerebral oxygenation-particularly mean levels and cumulative desaturation burden within the first 12-24\u2005h-may correlate with adverse biomarkers or neuroimaging findings and poorer later cognitive performance. Hemodynamic disturbance, oxidative stress, and inflammation may further shape the relationship between rScO2 abnormalities and neurological injury risk. Overall, perioperative rScO2 trends and desaturation burden may support neurological risk stratification and individualized physiological assessment, but standardized metrics, multimodal monitoring strategies, and prospective studies with long-term neurodevelopmental endpoints are needed to define actionable targets.\n\nID: 42488212\nTitle: Nutritional substrates and microglial metabolic fitness in brain aging and Alzheimer's disease: from lipid handling to TREM2-linked translation.\nAbstract: Alzheimer's disease is increasingly viewed as a disorder in which age-related disturbances in microglial metabolism and the handling of nutritional substrates contribute to progressive loss of protective function. This review examines how lipids and ketone bodies shape microglial metabolic fitness in the aging brain and in Alzheimer's disease, and how these effects intersect with triggering receptor expressed on myeloid cells 2 (TREM2) signaling and translational biomarkers. Available evidence indicates that early compensatory glycolysis may give way to chronic bioenergetic failure, while cholesterol and lipoprotein trafficking, lipid droplet accumulation, ketone-body signaling, and TREM2-associated lysosomal pathways influence plaque engagement, phagocytosis, and inflammatory responses. The review also considers how apolipoprotein E genotype, brain region, sex, disease stage, and model system condition translation from experimental models to human disease. Fluid, imaging, and tissue readouts are therefore discussed as stage- and context-dependent proxies rather than fixed signatures. Overall, nutritional strategies and microglia-targeted interventions are most likely to be informative when aligned with disease stage and biological context.\n\nID: 42487693\nTitle: Microglial Sestrin2 alleviates depressive-like behaviors and cognitive impairment in a YTHDF1-dependent manner.\nAbstract: This study aims to investigate the role of microglial Sestrin2 in chronic unpredictable stress (CUS)-induced depressive-like behaviors and cognitive impairment in mice, and to explore the upstream molecular mechanism underlying the abnormal expression of microglial Sestrin2. Microglia-specific overexpression of Sestrin2 was achieved by injecting adeno-associated virus (AAV) into the CUS mouse hippocampus. Depressive-like behaviors were assessed using sucrose preference, tail suspension, and forced swim tests. Cognitive function was evaluated by the Morris water maze. Levels of IL-1\u03b2 and IL-6 in the hippocampus and cell supernatants were measured by ELISA. BV2 microglial cells were used for in vitro mechanistic studies. YTHDF1 siRNA and overexpressive lentivirus were used to regulate YTHDF1 expression in vitro. RNA immunoprecipitation was performed to demonstrate the physical interaction between YTHDF1 and Sestrin2 mRNA. Sestrin2 expression was significantly reduced in the hippocampus of CUS mice. Overexpression of Sestrin2 specifically in microglia ameliorated CUS-induced depressive-like behaviors, cognitive impairment, and inflammatory levels. YTHDF1 expression was also reduced in the CUS hippocampus. Mechanistically, YTHDF1 bound to Sestrin2 mRNA and knockdown of YTHDF1 decreased Sestrin2 expression. Molecular biology prediction results showed that positions 1943 and 2,114 of Sestrin2 mRNA are high-confidence N6-methyladenosine (m6A) modification sites. Mutation of the 2,114 site on Sestrin2 mRNA inhibited the effect of YTHDF1 on 3Flag expression. Furthermore, YTHDF1 knockdown promoted IL-1\u03b2 and IL-6 production in BV2 cells, which was reversed by Sestrin2 overexpression. Microglial Sestrin2 alleviates depressive-like behaviors, cognitive impairment and neuroinflammation. YTHDF1 regulates Sestrin2 expression via an m6A-dependent mechanism, and the YTHDF1-Sestrin2 axis may represent a novel therapeutic target for major depressive disorder.\n\nID: 42487691\nTitle: The potential role of aberrant microglial synaptic pruning in the neurodevelopmental pathogenesis of tourette syndrome.\nAbstract: Tourette syndrome is a neurodevelopmental disorder traditionally attributed to dopamine system hyperactivity within the cortico-striato-thalamo-cortical circuitry. However, classical neurotransmitter hypotheses fail to fully explain the spatiotemporal and developmental specificities of the disorder. Consequently, research focus has shifted toward the neuroimmune microenvironment, specifically the role of microglia. This review aims to comprehensively explore the potential mechanisms of microglia-mediated aberrant synaptic pruning in the pathogenesis of tourette syndrome and to evaluate emerging therapeutic strategies. Methodologically, the study employs a narrative review approach to synthesize current neuroimmunobiology literature to reconstruct the pathological trajectory from early immune dysregulation to targeted interneuron impairment. Additionally, it conceptually explores natural product active monomers through a multi-target network pharmacology framework and assesses the translational potential of engineered nanodelivery systems. The findings indicate that genetic susceptibilities, such as histidine decarboxylase gene mutations, interact with environmental stressors, like maternal immune activation, to induce a chronically primed state in basal ganglia microglia. These primed innate immune cells are hypothesized to execute excessive synaptic pruning against highly vulnerable parvalbumin-expressing fast-spiking interneurons, a process significantly facilitated by the pathological downregulation of presynaptic protective signals. The physical loss of this local gamma-aminobutyric acid-ergic inhibitory network attenuates feedforward inhibition on medium spiny neurons, potentially contributing to macroscopic dopaminergic disinhibition. To address these mechanisms, multi-target natural therapies delivered via intelligent nanoplatforms present a theoretically promising approach to penetrate the blood-brain barrier and reverse pathological microglial phenotypes. Ultimately, this manuscript proposes a perspective of tourette syndrome as a microstructural developmental disorder of the circuitry rather than a mere neurotransmitter imbalance, providing a critical theoretical foundation for developing precise, next-generation neuroimmune-modulating interventions.\n\nID: 42487363\nTitle: Correlation between Glasgow Coma Scale Pupil Score and Brain Computed Tomography Scan Findings in Head Trauma Patients.\nAbstract: Traumatic brain injury is a leading cause of morbidity and mortality worldwide, necessitating rapid neurological assessment for early triage and management. The Glasgow Coma Scale-Pupils (GCS-P) score integrates the GCS with pupillary reactivity to improve the prediction of intracranial injury severity. This study aims to examine the correlation between GCS-P scores at presentation and brain CT findings in patients with head trauma, particularly in a semi-urban Indian emergency setting where CT access is often delayed, to validate GCS-P as a practical triage tool in the resource-limited environments. This retrospective study enrolled 300 adult patients with acute head injuries presenting over 3 months. Patients underwent standardized neurological evaluation including GCS and pupillary assessments followed by noncontrast CT imaging within 2 h. The GCS-P score was computed by subtracting the pupil reactivity score from total GCS. CT findings were categorized by injury severity (normal, mild, moderate, and severe). Spearman's rank correlation analysis assessed the relationship between GCS-P scores and CT severity. The mean age was 37.6 \u00b1 15.8 years; 79.3% were male, and road traffic accidents were the predominant trauma mechanism (67%). The mean GCS-P score was 10.7 \u00b1 3.9. CT scans revealed severe injury in 23.3% of cases. A strong negative correlation existed between GCS-P score and CT severity (\u03c1 = -0.682, P < 0.001). Patients with severe CT findings had significantly lower GCS-P scores (5.9 \u00b1 2.4) than those with mild (12.4 \u00b1 2.1) or normal imaging (14.0 \u00b1 1.6) (P < 0.001). GCS-P is a reliable, practical tool for the early identification of severe intracranial injury, with a strong association with CT severity. Routine implementation of GCS-P scoring can enhance triage, neurosurgical decision-making, and resource allocation in emergency neurotrauma care. Further multicenter studies with long-term outcomes are warranted.

Although increased synovial angiogenesis is a hallmark of synovial inflammation, efficiency of the oxygen supply to the synovium is poor, leading to a hypoxic gradient that impacts differential cellular responses. This hypoxic gradient occurs as infiltrating cells and cells that reside within the joint increase their metabolic demand beyond what the highly dysregulated vasculature can supply. This hypoxic environment favours an increase in reactive oxygen species, leading to oxidative damage that further promotes inflammation. In this adverse microenvironment, synovial cells adapt to generate energy and switch their cellular metabolism from a resting regulatory state to a highly metabolically active state, enabling them to produce essential building blocks to support their proliferation. This metabolic shift results in the accumulation of metabolic intermediates that function as signalling molecules, which further dictate the inflammatory response. However, the synovium is a complex multicellular tissue, and the specific cellular reliance on oxygen and metabolites differs across the synovium. Cellular demands depend on anatomical location, cell-cell interactions and competition for nutrients. Understanding the complex interplay between hypoxia-induced signalling pathways, oxidative stress and inflammatory responses will provide a better insight into the underlying mechanisms of disease pathogenesis.\n\nID: 42486823\nTitle: [Tongqiao Huoxue Decoction-medicated rat cerebrospinal fluid attenuates oxygen and glucose deprivation-induced neuronal injury by suppressing fibrinogen-mediated NLRP3 inflammasome activation].\nAbstract: To examine the protective effects of cerebrospinal fluid from Tongqiao Huoxue Decoction-treated rats (TQHXD-CSF) against oxygen and glucose deprivation and reoxygenation (OGD/R)-induced injury in murine BV-2 microglial cells and co-cultured HT22 cells. In a Transwell co-culture system of BV-2 and HT22 cells, OGD/R+fibrinogen (FIB) injury was induced in BV-2 cells followed by treatment with TQHXD-CSF intervention, and HT22 cells in the lower chamber were cultured under normal conditions. The cells were observed for changes in cell morphology, viability, intracellular ROS level, apoptosis, M1/M2 polarization, and FIB-containing extracellular vesicles (EVs). The cellular expressions of NLRP3, ASC, caspase-1, GSDMD, IL-1\u03b2, and IL-18 were quantified using Western blotting, and FIB-NLRP3 binding was confirmed by pull-down assay. OGD/R+FIB injury caused polarization of BV-2 cells to the pro-inflammatory M1 phenotype, increased CD86 expression and release of FIB-containing EVs, and activated the NLRP3 inflammasome. The co-cultured HT22 cells showed reduced cell viability, elevated ROS, and increased cells apoptosis. Treatment with TQHXD-CSF promoted M2 polarization in BV-2 cells, upregulated CD206 expression, suppressed FIB+ EVs secretion, and inhibited NLRP3 inflammasome activation in HT22 cells, which showed significantly lowered expressions of NLRP3, ASC, caspase-1, GSDMD, IL-1\u03b2, and IL-18 proteins and hence reduced inflammatory injury and cell apoptosis. Pull-down assay confirmed direct FIB and NLRP3 binding. In the co-culture system of BV-2 cells and HT22 cells, TQHXD-CSF treatment protects HT22 cells against OGD/R+FIB-induced injury by inhibiting FIB-containing EVs release from BV-2 cells and suppressing NLRP3 inflammasome activation. \u76ee\u7684: \u63a2\u8ba8\u901a\u7a8d\u6d3b\u8840\u6c64\u542b\u836f\u8111\u810a\u6db2\uff08TQHXD-CSF\uff09\u5bf9\u6c27\u7cd6\u5265\u593a/\u590d\u7cd6\u590d\u6c27\uff08OGD/R\uff09\u635f\u4f24\u5c0f\u9f20\u5c0f\u80f6\u8d28\u7ec6\u80de\uff08BV-2\uff09\u708e\u75c7\u635f\u4f24\u7684\u4fee\u590d\u4f5c\u7528\uff0c\u4ee5\u53ca\u5176\u5bf9\u5171\u57f9\u517b\u4f53\u7cfb\u4e2d\u795e\u7ecf\u5143\uff08HT22\uff09\u7ec6\u80de\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u91c7\u7528Transwell\u5171\u57f9\u517b\u4f53\u7cfb\uff0c\u5c06BV-2\u7ec6\u80de\u4e0eHT22\u7ec6\u80de\u8fdb\u884c\u5171\u57f9\u517b;\u5bf9Transwell\u5c0f\u5ba4\u4e2dBV-2\u7ec6\u80de\u5efa\u7acbOGD/R+FIB\u635f\u4f24\u6a21\u578b\u540e\uff0c\u7ed9\u4e88TQHXD-CSF\u5e72\u9884\uff0c\u4e0b\u5c42HT22\u7ec6\u80de\u6b63\u5e38\u57f9\u517b\u3002\u901a\u8fc7\u5012\u7f6e\u663e\u5fae\u955c\u89c2\u5bdf\u5404\u7ec4BV-2\u7ec6\u80de\u5f62\u6001\u53d8\u5316;\u91c7\u7528CCK-8\u6cd5\u68c0\u6d4b\u5404\u7ec4\u7ec6\u80de\u5b58\u6d3b\u7387;\u6d41\u5f0f\u7ec6\u80de\u672f\u5206\u6790\u7ec6\u80de\u5185\u6d3b\u6027\u6c27\uff08ROS\uff09\u542b\u91cf\u53ca\u7ec6\u80de\u51cb\u4ea1\u7387;CD86/CD206\u514d\u75ab\u8367\u5149\u53cc\u67d3\u6cd5\u89c2\u5bdfBV-2\u7ec6\u80de\u6781\u5316\u8868\u578b;\u900f\u5c04\u7535\u955c\u7ed3\u5408\u6d41\u5f0f\u7ec6\u80de\u672f\u9274\u5b9a\u5e76\u5b9a\u91cf\u542b\u7ea4\u7ef4\u86cb\u767d\u539f\uff08FIB\uff09\u7684\u7ec6\u80de\u5916\u56ca\u6ce1\uff08EVs\uff09;Western blotting\u6cd5\u68c0\u6d4bNLRP3\u708e\u6027\u4f53\u76f8\u5173\u86cb\u767d\uff08NLRP3\u3001ASC\u3001Caspase-1\u3001GSDMD\uff09\u53ca\u708e\u75c7\u56e0\u5b50\uff08IL-1\u03b2\u3001IL-18\uff09\u7684\u8868\u8fbe\u6c34\u5e73;Pull-down\u5b9e\u9a8c\u9a8c\u8bc1FIB\u4e0eNLRP3\u86cb\u767d\u7684\u76f8\u4e92\u4f5c\u7528\u3002\u7ed3\u679c: OGD/R+FIB\u635f\u4f24\u53ef\u663e\u8457\u8bf1\u5bfcBV-2\u7ec6\u80de\u5411M1\u578b\u4fc3\u708e\u8868\u578b\u6781\u5316\uff0c\u4e0a\u8c03CD86\u8868\u8fbe\u6c34\u5e73\uff0c\u589e\u52a0\u542bFIB\u7684EVs\u91ca\u653e\uff0c\u6fc0\u6d3bNLRP3\u708e\u6027\u4f53\u901a\u8def\uff08P<0.01\uff09;\u8fdb\u800c\u5bfc\u81f4\u5171\u57f9\u517b\u7684HT22\u7ec6\u80de\u6d3b\u529b\u4e0b\u964d\u3001ROS\u751f\u6210\u589e\u591a\u3001\u51cb\u4ea1\u7387\u5347\u9ad8\uff08P<0.01\uff09\u3002TQHXD-CSF\u5e72\u9884\u540e\uff0c\u53ef\u663e\u8457\u4fc3\u8fdbBV-2\u7ec6\u80de\u5411M2\u578b\u6297\u708e\u8868\u578b\u6781\u5316\uff0c\u4e0a\u8c03\u6297\u708e\u6807\u5fd7\u7269CD206\u8868\u8fbe\uff0c\u51cf\u5c11\u542bFIB\u7684EVs\u5206\u6ccc\uff08P<0.01\uff09;\u540c\u65f6\u53ef\u663e\u8457\u6291\u5236BV-2\u7ec6\u80de\u6d3b\u5316\u4ecb\u5bfc\u7684HT22\u7ec6\u80de\u4e2dNLRP3\u3001ASC\u3001Caspase-1\u3001GSDMD\u3001IL-1\u03b2\u3001IL-18\u7684\u86cb\u767d\u8868\u8fbe\uff0c\u6291\u5236NLRP3\u708e\u6027\u4f53\u8fc7\u5ea6\u6fc0\u6d3b\uff0c\u660e\u663e\u6539\u5584HT22\u7ec6\u80de\u7684\u708e\u75c7\u635f\u4f24\u53ca\u51cb\u4ea1\u60c5\u51b5\uff08P<0.01\uff09\u3002Pull-down\u5b9e\u9a8c\u8bc1\u5b9e\uff0cFIB\u4e0eNLRP3\u86cb\u767d\u4e4b\u95f4\u5b58\u5728\u76f4\u63a5\u76f8\u4e92\u4f5c\u7528\u3002\u7ed3\u8bba: TQHXD-CSF\u53ef\u901a\u8fc7\u6291\u5236OGD/R+FIB\u635f\u4f24\u540eBV-2\u7ec6\u80de\u91ca\u653e\u542bFIB\u7684EVs\uff0c\u963b\u65adNLRP3\u708e\u6027\u4f53\u6fc0\u6d3b\u4ecb\u5bfc\u7684\u708e\u75c7\u53cd\u5e94\uff0c\u5bf9HT22\u7ec6\u80de\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u51cf\u8f7b\u7f3a\u8840\u6027\u8111\u5352\u4e2d\u540e\u7684\u795e\u7ecf\u708e\u75c7\u635f\u4f24\u63d0\u4f9b\u5b9e\u9a8c\u4f9d\u636e\u3002.\n\nID: 42486819\nTitle: [Gastrodin alleviates hypobaric hypoxia-induced brain injury in rats by reducing neuronal ferroptosis via the P53/SLC7A11/GPX4 signaling axis].\nAbstract: To investigate the neuroprotective effect of gastrodin (GAS) against hypobaric hypoxia (HH)-induced brain injury in rats and the underlying mechanism. Twenty-four adult SD rats were randomized equally into normoxic control group, HH model group, low-dose (100 mg/kg) GAS group (HH+GAS-L group), and high-dose (200 mg/kg) GAS group (HH+GAS-H group). In the latter 3 groups, the rats were exposed to HH in a hypobaric oxygen chamber for 24 h to simulate the condition at an altitude of 6000 m, and GAS was administered intraperitoneally once daily for 7 days. Cerebral cortex tissues were collected for analysis of P53, SLC7A11, and GPX4 protein expressions using Western blotting and for determination of the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and ferrous ion (Fe\u00b2\u207a). In cultured HT22 neurons exposed to oxygen-glucose deprivation (OGD), the effects of GAS (500 \u03bcmol/L), nutlin-3 (a P53 agonist; 10 \u03bcmol/L) or their combination were examined on ferroptosis-related protein expressions, intracellular ROS, lipid peroxidation, MDA, GSH, cell viability, mitochondrial membrane potential, and Fe\u00b2\u207a levels. In the rat models of HH, GAS treatment significantly inhibited P53 expression, upregulated SLC7A11 and GPX4 proteins, markedly reduced Fe\u00b2\u207a, ROS, and MDA levels, and increased GSH content in the cerebral cortex. In cultured HT22 neurons, GAS treatment effectively alleviated OGD-induced cell ferroptosis as shown by decreased P53 expression, increased SLC7A11 and GPX4 expressions, and lowered levels of intracellular ROS generation, lipid peroxidation, and Fe\u00b2\u207a accumulation, along with obvious restoration of GSH levels, cell viability, and mitochondrial membrane potential. The protective effects of GAS was markedly attenuated by activation of the P53 pathway using nutlin-3. GAS produces neuroprotective effects against HH-induced brain injury in rats by inhibiting neuronal ferroptosis via regulating the P53/SLC7A11/GPX4 signaling pathway. \u76ee\u7684: \u7814\u7a76\u5929\u9ebb\u7d20\uff08GAS\uff09\u5bf9\u9ad8\u539f\u4f4e\u538b\u7f3a\u6c27\uff08HH\uff09\u6027\u8111\u635f\u4f24\u7684\u795e\u7ecf\u4fdd\u62a4\u4f5c\u7528\uff0c\u5e76\u63a2\u8ba8\u5176\u673a\u5236\u662f\u5426\u4e0e\u8c03\u8282P53/SLC7A11/GPX4\u4fe1\u53f7\u901a\u8def\u3001\u6291\u5236\u795e\u7ecf\u5143\u94c1\u6b7b\u4ea1\u76f8\u5173\u3002\u65b9\u6cd5: \u4f53\u5185\u5b9e\u9a8c\u9009\u53d624\u53ea\u6210\u5e74SD\u5927\u9f20\uff0c\u968f\u673a\u5206\u4e3a4\u7ec4\uff08n=6\uff09:\u5e38\u538b\u5e38\u6c27\u5bf9\u7167\u7ec4\uff08Nor\uff09\u3001\u4f4e\u538b\u7f3a\u6c27\u6a21\u578b\u7ec4\uff08HH\uff09\u3001\u5929\u9ebb\u7d20\u4f4e\u5242\u91cf\u7ec4\uff08HH+GAS-L\uff0c100 mg/kg\uff09\u3001\u5929\u9ebb\u7d20\u9ad8\u5242\u91cf\u7ec4\uff08HH+GAS-H\uff0c200 mg/kg\uff09\u3002\u9664\u5bf9\u7167\u7ec4\u5916\uff0c\u5176\u4f59\u5404\u7ec4\u5927\u9f20\u7f6e\u4e8e\u6a21\u62df\u6d77\u62d46000 m\u7684\u4f4e\u538b\u6c27\u8231\u4e2d\u6301\u7eed\u66b4\u973224 h\u4ee5\u5efa\u7acbHH\u6a21\u578b\u3002\u5929\u9ebb\u7d20\u4e8e\u9020\u6a21\u540e\u8179\u8154\u7ed9\u836f\uff0c1\u6b21/d\u3002\u53d6\u7b2c7\u5929\u7684\u8111\u76ae\u5c42\u8fdb\u884cWestern blotting\u68c0\u6d4bP53\u3001SLC7A11\u53caGPX4\u86cb\u767d\u8868\u8fbe\uff0c\u540c\u65f6\u6d4b\u5b9a\u7ec4\u7ec7\u5185\u6d3b\u6027\u6c27\u6807\u5fd7\u7269\uff08DHE\uff09\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u8c37\u80f1\u7518\u80bd\uff08GSH\uff09\u53ca\u4e9a\u94c1\u79bb\u5b50\uff08Fe\u00b2\u207a\uff09\u7684\u542b\u91cf\u3002\u4f53\u5916\u57f9\u517bHT22\u795e\u7ecf\u5143\uff0c\u5206\u4e3a:\u5bf9\u7167\u7ec4\uff08Control\uff09\u3001\u6a21\u578b\u7ec4\uff08OGD\uff09\u3001\u5929\u9ebb\u7d20\u5e72\u9884\u7ec4\uff08OGD+GAS\uff0c500 \u03bcmol/L\uff09\u3001P53\u6fc0\u52a8\u5242\u7ec4\uff08OGD+Nutlin-3\uff0c10 \u03bcmol/L\uff09\u53ca\u8054\u5408\u5904\u7406\u7ec4\uff08OGD+GAS+Nutlin-3\uff09\u3002\u68c0\u6d4b\u6307\u6807\u5305\u62ec\u94c1\u6b7b\u4ea1\u76f8\u5173\u86cb\u767d\u8868\u8fbe\u3001\u7ec6\u80de\u5185\u6d3b\u6027\u6c27\uff08DCFH-DA\uff09\u3001\u8102\u8d28\u8fc7\u6c27\u5316\uff08BODIPY-C11\uff09\u3001MDA\u3001GSH\u3001\u7ec6\u80de\u5b58\u6d3b\u7387\uff08CCK-8\uff09\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\uff08JC-1\uff09\u53ca\u4e9a\u94c1\u79bb\u5b50\uff08FerroOrange\uff09\u3002\u7ed3\u679c: \u52a8\u7269\u5b9e\u9a8c\u663e\u793a\uff0c\u4e0eHH\u7ec4\u76f8\u6bd4\uff0c\u5929\u9ebb\u7d20\u663e\u8457\u6291\u5236P53\u8868\u8fbe\uff0c\u4e0a\u8c03SLC7A11\u4e0eGPX4\u86cb\u767d\u6c34\u5e73\uff08P<0.05\uff09\uff0c\u5e76\u663e\u8457\u964d\u4f4e\u8111\u76ae\u5c42\u7ec4\u7ec7Fe\u00b2\u207a\u3001ROS\u548cMDA\u542b\u91cf\uff0c\u63d0\u9ad8GSH\u6c34\u5e73\uff08P<0.05\uff09\u3002\u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u4e00\u81f4\uff0c\u5929\u9ebb\u7d20\u6709\u6548\u51cf\u8f7b\u4f4e\u538b\u7f3a\u6c27\u8bf1\u5bfc\u7684\u94c1\u6b7b\u4ea1\uff0c\u8868\u73b0\u4e3aP53\u8868\u8fbe\u4e0b\u964d\uff0cSLC7A11\u4e0eGPX4\u8868\u8fbe\u5347\u9ad8\uff08P<0.05\uff09\uff0c\u7ec6\u80de\u5185ROS\u751f\u6210\u3001\u8102\u8d28\u8fc7\u6c27\u5316\u548cFe\u00b2\u207a\u84c4\u79ef\u88ab\u6291\u5236\uff0c\u540c\u65f6GSH\u542b\u91cf\u3001\u7ec6\u80de\u6d3b\u6027\u548c\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u663e\u8457\u6062\u590d\uff08P<0.05\uff09\u3002\u800c\u4f7f\u7528Nutlin-3\u6fc0\u6d3bP53\u4fe1\u53f7\u901a\u8def\u540e\uff0c\u5929\u9ebb\u7d20\u7684\u4fdd\u62a4\u4f5c\u7528\u88ab\u660e\u663e\u9006\u8f6c\uff08P<0.05\uff09\u3002\u7ed3\u8bba: \u5929\u9ebb\u7d20\u53ef\u80fd\u901a\u8fc7\u8c03\u63a7P53/SLC7A11/GPX4\u4fe1\u53f7\u901a\u8def\u6291\u5236\u795e\u7ecf\u5143\u94c1\u6b7b\u4ea1\uff0c\u4ece\u800c\u5bf9\u9ad8\u539f\u4f4e\u538b\u7f3a\u6c27\u6027\u8111\u635f\u4f24\u53d1\u6325\u795e\u7ecf\u4fdd\u62a4\u4f5c\u7528\u3002.\n\nID: 42486777\nTitle: Beyond word count: a pilot study of the verbal fluency task in chronic mild traumatic brain injury.\nAbstract: To examine the clustering and switching behaviours, beyond total word count, as indicators of subtle executive dysfunction in individuals with and without a history of mild traumatic brain injury (mTBI), and to determine whether subcomponent analyses reveal cognitive inefficiencies overlooked by standard assessments. Thirty-five university students (mTBI = 9; controls = 26) aged 18-24 years completed phonemic (FAS) and semantic (animal naming) verbal fluency tasks. Total correct responses, mean cluster size and number of switches were analysed. Compared with controls, individuals with mTBI produced fewer 'S' words (z = 2.66, P = 0.007, r = 0.45) and semantic switches (z = 2.45, P = 0.015, r = 0.41). Both groups were significantly different in semantic and phonemic clusters (mTBI: z = 2.22, P = 0.026, r = 0.74; controls: z = 3.51; P < 0.001, r = 0.69). No group differences were observed for phonemic switching. Findings indicate subtle reductions in cognitive flexibility and verbal productivity in individuals with chronic mTBI. Clustering and switching analyses in verbal fluency tasks may detect subtle, executive deficits in individuals with chronic mTBI that are not captured by total word count alone. These findings support the feasibility of subcomponent verbal fluency measures as sensitive tools for long-term mTBI assessment and monitoring.\n\nID: 42466852\nTitle: Gut microbiota-nanoparticle interactions in Parkinson's disease: mechanistic insights and therapeutic perspective.\nAbstract: This review introduces the 'nanomaterial-microbiome-brain interface' as a conceptual framework uniting three systems: gut microbiota, nanoparticles, and neurodegeneration. We synthesize evidence showing that titanium dioxide, silver, and zinc oxide nanoparticles differentially alter microbial composition. These microbial shifts intersect with established gut-brain mechanisms, including short-chain fatty acid production and immune modulation, providing plausible pathways linking nanomaterial exposure to neurological outcomes. We propose the 'nanomaterial-microbiome-brain interface' as a novel conceptual framework with twofold relevance-serving both as a potential contributor to Parkinson's disease pathogenesis through unintentional environmental exposure, and as an underexplored avenue for therapeutic intervention. Critical knowledge gaps persist. Addressing these gaps will require integrated approaches that bridge nanomaterial research, microbiome science, and neurodegeneration studies.\n\nID: 42460525\nTitle: High Levels of Plasma Neurturin Partially Mediate the Protective Effect of Reduced Ruminococcus2 Abundance on Multiple Sclerosis: A Mendelian Randomization Study.\nAbstract: Genetic evidence implicates the contribution of the gut-brain axis to neurodegenerative diseases (NDDs). Alterations in gut microbiota and inflammation are key pathophysiological contributors. Elucidating the genetic basis and the role of cytokines can provide insights into mechanisms linking gut microbial composition to neurodegeneration. Using aggregated statistics from five large-scale Genome-Wide Association Studies (GWAS) on Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple sclerosis, and amyotrophic lateral sclerosis, bidirectional two-sample Mendelian Randomization (MR) was used to examine the associations. A two-step multivariable Mendelian randomization approach incorporates data from 91 cytokines to explore potential mediators. The study reveals 18 positive and 17 negative effects between gut microbiota and NDDs, as well as 10 positive and 10 negative effects between cytokines and NDDs. Remarkably, mediation analysis identified a causal pathway, with evidence that plasma neurturin levels partially mediate the association from genus Ruminococcus2 to multiple sclerosis, with a mediation proportion of 19.19% (OR = 1.038, 95% CI = 1.001-1.086, P = 0.044). No pleiotropy or heterogeneity was detected. These MR findings provide compelling evidence for a genetically anchored gutimmune-brain network in NDDs, with cytokines as intermediates. Bidirectional effects highlight disease-specific microbial signatures and inflammatory contexts. The Ruminococcus2-neurturin pathway in multiple sclerosis may offer mechanistic specificity, aligning with neurotrophic and anti-inflammatory signaling pathways. This study emphasizes the importance of gut microbiota alterations in NDDs and explores inflammation's partial intermediary role. The findings suggest potential targets for personalized neurodegeneration prevention strategies.\n\nID: 42458926\nTitle: The gut microbiota-metabolome axis mediates the adaptive protective effects of a high-altitude probiotic against distinct aging etiologies.\nAbstract: Aging is a major driver of chronic diseases and mortality, yet effective interventions against distinct aging etiologies remain limited. Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n\nID: 42456856\nTitle: Selenium nanoparticles modulate gut-brain axis via NRF2 to attenuate Parkinsonian neurotoxicity.\nAbstract: Parkinson's disease (PD) is characterized by progressive dopaminergic neurodegeneration driven by mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired gut-brain communication. Here, we report a biogenic selenium nanoparticle (Se-NP) platform derived from mussel tissue and demonstrate its nano-enabled neuroprotective efficacy in a rotenone-induced zebrafish model of Parkinsonian neurotoxicity. Selenium was extracted from the tissue of Perna viridis (mussel) and used for the biogenic synthesis of Se-NPs through a green reduction approach under controlled conditions. The mussel-derived Se-NPs exhibited high redox-buffering capacity, enabling efficient attenuation of rotenone-induced oxidative stress, lipid peroxidation, and nitric oxide accumulation. Se-NP treatment preserved dopaminergic neuronal architecture, reduced microglial activation, and maintained gut epithelial integrity, indicating coordinated neuro-intestinal protection. Mechanistically, Se-NPs activated NRF2-driven antioxidant signaling through upregulation of NFE2L2a and HMOX1a and suppression of KEAP1a, thereby restoring endogenous antioxidant defences. At the neurovascular interface, Se-NPs enhanced blood-brain barrier integrity by upregulating tight junction proteins Claudin-5a and ZO-1, linking redox regulation to barrier stabilization. Notably, Se-NPs restored dopaminergic gene expression, modulated inflammatory signaling pathways, and normalized gut-associated microbial markers, thereby supporting nano-mediated regulation of the gut-brain axis. Collectively, this study establishes biogenic Se-NPs as a multifunctional nanotherapeutic that integrates antioxidant signaling, neurovascular protection, and gut-brain axis modulation to counteract rotenone-induced neurodegeneration, highlighting their potential as a nano-enabled strategy for PD intervention.\n\nID: 42451206\nTitle: KetoFLEX 12/3 Diet and Cognitive Health: A Precision-Nutrition Perspective on Mechanisms, Emerging Evidence, and Future Directions.\nAbstract: Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder characterized by impaired glucose metabolism, mitochondrial dysfunction, inflammation, oxidative stress, and progressive cognitive decline. Because currently available pharmacological therapies provide only modest symptomatic benefit, nutrition-based interventions are increasingly being explored as complementary strategies for supporting brain metabolism and cognitive resilience. The KetoFLEX 12/3 dietary pattern, developed within the ReCODE (Reversal of Cognitive Decline) program, is a plant-rich, mildly ketogenic nutrition and lifestyle framework that integrates low-glycemic nutrition, time-restricted eating, and personalized metabolic optimization. The diet emphasizes deeply pigmented non-starchy vegetables, extra-virgin olive oil, nuts and seeds, omega-3-rich seafood, and minimally processed foods while limiting refined carbohydrates, sugars, processed foods, and selected grains and dairy products. Emerging mechanistic and clinical evidence suggests that KetoFLEX 12/3 may influence several pathways relevant to AD pathophysiology, including insulin signaling, mitochondrial bioenergetics, neuroinflammation, oxidative stress, autophagy, detoxification pathways, and gut-brain axis function. Observational findings from ReCODE-related studies have reported improvements in metabolic parameters, mood-related outcomes, cognitive measures, and brain volumetrics in participants adhering to multimodal precision-medicine interventions incorporating the KetoFLEX principles. Compared with traditional dietary models such as the Mediterranean or MIND diets, KetoFLEX 12/3 places greater emphasis on mild nutritional ketosis, meal timing, and metabolic personalization based on factors such as ApoE genotype and insulin sensitivity. The objective of this Perspective is to examine the mechanistic rationale, emerging evidence, limitations, and future research priorities for KetoFLEX 12/3 as a precision-nutrition framework for cognitive health in AD. Although much of the current evidence remains mechanistic, observational, or derived from multimodal intervention studies, the framework offers a biologically plausible precision-nutrition model that may inform future research and clinical investigation in cognitive decline.\n\nID: 42437581\nTitle: Peripheral nerve injury-induced upregulation of acyl-CoA synthetase 2 contributes to neuropathic pain via mediating microglial autophagy disruption in the spinal dorsal horn.\nAbstract: Acyl-CoA synthetase 2 (ACSS2), by producing acetyl-coenzyme A from acetate in the nucleus, facilitates histone acetylation and regulates gene expression. However, the role of ACSS2 in neuropathic pain remains unclear. Herein, we found that lumbar 5 spinal nerve ligation (SNL) increased ACSS2 expression predominately in microglia of the spinal dorsal horn. This increase was accompanied by elevated histone H3K27 acetylation (H3K27ac), enhanced raptor expression, activated mTORC1/TFEB signaling, raised p62, and reduced LC3II/LC3I ratio. Repeated intrathecal or intravenous injections of ACSS2 inhibitor (ACSS2i) partially prevented development of, and reversed established, neuropathic pain in male and female rats. Microglia-specific AAV-F4/80-ACSS2 shRNA injection into L5 spinal dorsal horn alleviated SNL-induced pain hypersensitivity, counteracted the increase in H3K27ac and rescued mTORC1/TFEB signaling-mediated autophagy impairment. SNL-enhanced binding of SP1, a transcriptional regulator of raptor, and the elevation of H3K27ac at the raptor promoter were inhibited by AAV-F4/80-ACSS2 shRNA. The increases of IL-1\u03b2 and TNF-\u03b1 production after SNL were also reversed by these interventions. Microglia-specific Acss2 knockout (Acss2cKO) mitigated SNL-induced abnormal pain, and prevented microglial autophagy disruption in male and female mice. ACSS2i treatment decreased H3K27ac, reduced SP1 binding with raptor promoter, and restored autophagy disruption in cultured BV2 cells following LPS stimulation. In addition, knockdown of ACSS2 specifically in neurons or astrocytes partially reduced pain following SNL. Collectively, our findings suggest that the peripheral nerve injury-induced upregulation of ACSS2 in the spinal dorsal horn contributes to neuropathic pain might partially through regulating raptor expression and subsequently activating mTORC1/TFEB signaling-mediated microglial autophagy disruption.\n\nID: 42427525\nTitle: Notch Signaling Reprograms Glial Lipid Metabolism to Promote Hypoxia Resistance.\nAbstract: Hypoxia poses a major threat to the developing nervous system, where high metabolic demand is required to support brain growth, glial and neuronal maturation, and function. Although glial cells are essential for maintaining neural homeostasis under stress, how specific glial subtypes remodel metabolism to promote hypoxia tolerance remains poorly understood. Here, we identify a Notch-dependent lipid metabolic program in excitatory amino acid transporter 1 (Eaat1)-positive glia that supports hypoxia adaptation in the developing Drosophila larval brain. Using stimulated Raman scattering (SRS) microscopy combined with deuterium-labeled metabolic probes, we visualized substrate-specific metabolic activity in vivo at subcellular resolution. In control, non-adapted flies, we found that acute hypoxia markedly increased de novo lipogenesis in Eaat1-positive glia. In flies adapted to chronic hypoxia, Eaat1-positive glia exhibited a pre-programmed metabolic shift, characterized by reduced glucose-derived lipogenesis and enhanced acetate-derived lipid synthesis. Constitutive activation of Notch signaling in Eaat1-positive glia was sufficient to phenocopy this acetate-favored lipogenic state, suggesting that Notch promotes metabolic plasticity under oxygen-limited conditions. To define the transcriptional programs associated with this response, we performed single-nucleus RNA sequencing (snRNA-seq) of the developing Drosophila central nervous system and mapped Eaat-1expressing cell populations across hypoxia and Notch activation. Notch activation reshaped hypoxia-associated transcriptional responses and counteracted metabolic suppression caused by low oxygen. Together, our findings identify Eaat1-positiveglia as a metabolically adaptive glial population and reveal a conserved Notch-regulated mechanism that rewires lipid metabolism to support hypoxia tolerance in the developing brain. These results provide insight into glial metabolic strategies that may be relevant to hypoxia-associated neurological conditions, including neonatal hypoxic-ischemic brain injury and ischemic stroke.\n\nID: 42425421\nTitle: Dietary bioactive compounds and inflammaging: Pro-inflammatory triggers and geroprotective countermeasures.\nAbstract: Chronic low-grade inflammation (\"inflammaging\") is a key driver of age-related pathologies including cardiovascular disease, neurodegeneration, and metabolic syndrome. Diet plays a dual role in modulating this process, acting both as a source of pro-inflammatory molecular patterns and as a delivery system for geroprotective compounds. This review examines the pro-inflammatory dietary components (advanced glycation end products, lipid peroxidation products, oxysterols, trans fats, and microbiome-derived metabolites) that activate pattern recognition receptors and trigger inflammatory cascades, as well as the anti-inflammatory mechanisms of bioactive dietary compounds including polyphenols, omega-3 fatty acids, carotenoids, vitamins, and essential microelements. Evidence from cellular, animal, and clinical studies is synthesized to evaluate dietary interventions for healthy aging. PubMed and Google Scholar were systematically searched from inception through November 2025, with evidence quality and translational limitations critically appraised throughout. Pro-inflammatory dietary components activate nuclear factor-kappa B pathways, while geroprotective compounds demonstrate potent anti-inflammatory properties through multiple mechanisms: polyphenols (quercetin, EGCG, resveratrol, curcumin) inhibit pro-inflammatory signaling and activate sirtuin and Nrf2 pathways; omega-3 fatty acids reduce pro-inflammatory eicosanoids and increase specialized pro-resolving mediators; carotenoids, vitamins, and microelements (selenium, zinc, magnesium) suppress oxidative stress and modulate immune function. These dietary geroprotectors reduce inflammatory biomarkers in cellular and animal models, while clinical evidence in humans remains largely restricted to biomarker and healthspan-related endpoints rather than demonstrated lifespan extension. Optimized nutrition-emphasizing fruits, vegetables, legumes, nuts, whole grains, and omega-3-rich foods while limiting refined sugars and trans fats-represents a cornerstone intervention for mitigating inflammaging and promoting healthy longevity, with the Dietary Inflammatory Index providing a translational framework for implementation.\n\nID: 42422257\nTitle: Ligand-specific duality of aryl hydrocarbon receptor signaling in cognitive health: from environmental neurotoxicity to microbiome-mediated neuroprotection.\nAbstract: The aromatic hydrocarbon receptor (AhR) is a key molecular interface integrating environmental chemical signals with host-microbiome metabolism, with profound effects on brain function. This review systematically addresses the ligand-specific duality of AhR signaling in cognitive health, comparing the predominantly neurotoxic signaling driven by environmental polycyclic aromatic hydrocarbons (PAHs) with the predominantly neuroprotective signaling mediated by gut microbiota-derived tryptophan metabolites. However, this dichotomy is context-dependent rather than absolute. PAHs activate AhR in a sustained, high-affinity manner, engaging downstream NF-\u03baB neuroinflammation, NLRP3 inflammasome activation, oxidative stress, synaptic dysfunction, and transgenerational epigenetic alterations. In contrast, microbiota-derived metabolites such as indole-3-propionic acid (IPA) and kynurenic acid (KYNA) elicit transient, low-affinity AhR activation that engages cell-type-specific programs promoting anti-inflammatory responses, neurogenesis, blood-brain barrier integrity, and neuronal homeostasis. Critically, the outcome of AhR activation is modulated by ligand pharmacokinetics, cell-type identity, temporal dynamics of receptor engagement, and tissue-specific co-factor availability. These contextual variables determine whether AhR functions as a driver of neurodegeneration or a guardian of cognitive resilience. We further examine the divergent roles of AhR in Alzheimer's and Parkinson's diseases, where the balance between detrimental and protective ligands determines disease progression. Finally, we discuss therapeutic strategies targeting the AhR-gut-brain axis, including dietary modulation, probiotic interventions, and selective AhR modulators. Understanding the context-dependent outcomes of AhR activation provides a framework for developing precision approaches to preserve cognitive function and prevent neurodegeneration.\n\nID: 42422212\nTitle: Opposite regulatory effects of Blautia massiliensis and Blautia faecis on cognitive function, microglia and metabolite acetic acid in mice.\nAbstract: Cognitive impairment is a significant health problem worldwide, closely associated with the status of gut microbiota. Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis. Consequently, our findings indicate that Blautia massiliensis enhances cognitive function whereas Blautia faecis impairs it, and we speculate that differential acetate production may contribute to these opposing effects.\n\nID: 42418295\nTitle: Advances in the Core Role and Mechanisms of Mitochondrial Dysfunction in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder whose pathogenesis involves multi-level pathological alterations. This review aims to systematically elucidate the central role and multifaceted molecular mechanisms of mitochondrial dysfunction in the progression of AD. A comprehensive analysis of the existing literature was conducted, synthesizing findings from studies investigating mitochondrial involvement in AD pathology. The review focused on key mechanistic pathways, including energy metabolism deficits, oxidative stress, synaptic damage, mitochondrial dynamics, mitochondria-associated membranes (MAMs), mitophagy, and the gut-brain axis. The analysis revealed several critical mechanisms linking mitochondrial dysfunction to AD progression: (i) impaired mitochondrial energy metabolism, which establishes a causal relationship with oxidative stress and synaptic injury; (ii) dysregulation of mitochondrial fusion/fission dynamics, particularly the aberrant interactions of amyloid-beta (A\u03b2) and p-Tau with the fission protein Drp1 and the channel protein VDAC1; (iii) dysfunction of mitochondria-associated membranes (MAMs); (iv) defective mitophagy involving both the PINK1/Parkin pathway and receptor-mediated pathways; and (v) bidirectional crosstalk between mitochondria and the gut-brain axis. These interconnected pathways converge to amplify neuroinflammation and neuronal death. Accumulated evidence positions mitochondrial dysfunction as a critical hub that integrates A\u03b2/Tau pathology, neuroinflammation, and neuronal loss, thereby perpetuating a self-sustaining vicious cycle in AD. Targeting mitochondrial bioenergetics, dynamics, quality control, and the mitochondria-inflammation axis offers substantial therapeutic promise. Emerging small molecules such as SS31 and DDQ have demonstrated protective effects in preclinical models. Future investigations should prioritize mechanistic dissection and translational research to facilitate the clinical development of mitochondria-targeted therapies for AD.\n\nID: 42416058\nTitle: DPP-4 inhibitors in drug-resistant epilepsy: a hypothesized mechanism via the gut microbiota-short-chain fatty acids-glucagon-like peptide-1 axis.\nAbstract: Drug-resistant epilepsy (DRE) affects approximately one-third of patients with epilepsy and remains a major therapeutic challenge.Recent studies have demonstrated significant gut microbiota dysbiosis in patients with DRE, and certain interventions targeting the gut microbiota demonstrate therapeutic efficacy. However, pharmacological interventions that precisely modulate the gut microbiota in DRE have not yet been fully explored. This review aims to propose a systematic hypothesis that Dipeptidyl peptidase-4 inhibitors (DPP-4is) may alleviate peripheral and central pathological damage by regulating the \"gut microbiota-short-chain fatty acids (SCFAs) -glucagon-like peptide-1 (GLP-1) axis\", thereby reducing susceptibility to DRE. Existing studies indicate that: (1)DPP-4is possess neuroprotective effects in experimental epilepsy models, partly by enhancing endogenous GLP-1 signaling. (2)DPP-4is have been reported to modulate gut microbiota composition and increase the abundance of SCFA-producing bacteria in metabolic diseases. (3)SCFAs can promote GLP-1 secretion by activating free fatty acid receptors (FFAR2/3) and improve intestinal barrier function and inflammatory status in metabolic and neurodegeneration disease. However, it remains unclear whether this pathway mediates the effects of DPP-4is in epilepsy. (4)Enhanced peripheral GLP-1 signaling can further influence central nervous system homeostasis, including enhancing inhibitory synaptic transmission, attenuating neuroinflammation, oxidative stress, and inhibiting neuronal apoptosis, thereby reducing susceptibility to seizures. By integrating cross-contextual evidence, we propose that DPP-4is may exert protective effects on DRE through gut microbiota-SCFAs-GLP-1 axis.\n\nID: 42413884\nTitle: Ageing-driven gastrointestinal variability in Parkinson's disease: implications for oral levodopa pharmacokinetics and formulation design.\nAbstract: Parkinson's disease is a distinctly age-associated neurodegenerative disorder in which oral levodopa remains the therapeutic foundation, particularly in older adults. Yet with advancing age, the reliability of oral therapy progressively declines not simply due to inadequate dosing, but because ageing reshapes the gastrointestinal environment on which drug absorption depends. This review integrates evidence spanning neuromuscular decline, epithelial barrier fragility, altered luminal chemistry, immune dysregulation, microbiome remodelling, and enteric neurodegeneration to explain how the ageing gut generates exposure instability. Delayed gastric emptying, inconsistent proximal intestinal delivery, microbial drug metabolism, and real-world administration constraints collectively amplify pharmacokinetic variability, producing erratic onset, fluctuating plasma profiles, and reduced therapeutic predictability. Using levodopa as a clinically established model system, we extend these insights to the broader challenge of ensuring reliable performance of oral therapies in ageing populations. We argue that therapeutic success in older adults depends less on maximizing mean bioavailability and more on stabilising exposure under heterogeneous physiological and practical conditions. Accordingly, the review integrates ageing-associated gastrointestinal decline, altered luminal and epithelial determinants of drug absorption, pharmacokinetic instability, and formulation design responses into a unified translational framework for ageing-aware oral therapy. By reframing levodopa failure as a consequence of ageing-driven gut-drug instability, this review proposes an ageing-aware formulation framework and identifies exposure-stability endpoints to guide the development and evaluation of physiologically resilient oral therapies for older adults.\n\nID: 42413380\nTitle: \u03b2-sitosterol and next-generation neuroprotection for multi-target strategies and the gut-brain axis in neurodegenerative diseases.\nAbstract: Neurodegenerative disorders such as Alzheimer's and Parkinson's diseases arise from complex interactions among oxidative stress, neuroinflammation, metabolic dysfunction, and dysregulated signaling networks. This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints. Collectively, these findings position phytochemicals as promising candidates for multi-target disease modification and the development of next-generation neurotherapeutic strategies.\n\nID: 42411493\nTitle: Beyond Amyloid: Evolutionary and Immune-Metabolic Perspectives on Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is increasingly recognized as a multifactorial and systems-level disorder that extends beyond the classical amyloid cascade hypothesis. Rather than dismissing established concepts such as tau pathology, synaptic dysfunction, vascular compromise, mitochondrial abnormalities, and impaired proteostasis, emerging evidence suggests that these processes may interact dynamically with chronic immune activation, microbial signaling, and systemic metabolic stress. Recent studies examining the microbiome-gut-brain axis, chronic infection, innate immunity, and systemic immune-metabolic dysfunction have broadened the conceptual framework of AD pathogenesis. Importantly, amyloid-\u03b2 (A\u03b2) is now understood to possess evolutionarily conserved antimicrobial and immunomodulatory properties, suggesting that amyloid deposition may initially represent a protective host-defense response rather than solely a toxic pathological event. This perspective does not overturn the amyloid cascade model but instead reframes amyloid biology within a broader adaptive evolutionary context in which chronic or dysregulated activation becomes maladaptive during aging. The present opinion article integrates these converging concepts into a unified framework in which AD emerges from the prolonged interaction among immune responses, microbial exposures, metabolic disturbances, mitochondrial dysfunction, vascular injury, and age-associated failures in proteostatic resilience. This integrative interpretation seeks to humanize the disease process by viewing neurodegeneration not simply as isolated protein accumulation, but as the gradual exhaustion of ancient host-defense and energy-regulatory systems that were originally evolutionarily advantageous for survival.\n\nID: 42410293\nTitle: Neuroinflammation in neurodegenerative diseases: pathogenic pathways and emerging pharmacotherapeutic targets in Alzheimer's and Parkinson's disease.\nAbstract: Neuroinflammation is now widely recognized as a key contributor to the initiation and progression of neurodegenerative diseases, particularly Alzheimer's disease (AD) and Parkinson's disease (PD). Chronic activation of brain-resident immune cells, including microglia and astrocytes, in response to misfolded protein aggregates such as amyloid-\u03b2 and tau in AD and \u03b1-synuclein in PD, promotes maladaptive immune signaling, sustained cytokine release, and disruption of the blood-brain barrier (BBB). This chronic brain inflammation leads to synaptic dysfunction, neuronal loss and ultimately clinical deterioration. These processes are accompanied by disease-specific factors, such as inflammation of the gut-brain axis in PD and genetic modulators including APOE4, TREM2, and LRRK2. Furthermore, the development of fluid biomarkers together with neuroimaging techniques has improved early detection and monitoring of neuroinflammation leading to personalized therapeutic approaches. Clinical trials targeting microglial phenotypes, cytokine signaling, inflammasome activity, and genetic risk factors are emerging therapeutic strategies. Model limitations and heterogeneity of patients present challenges, but insights into neuroimmune interactions could provide a path forward for disease-modifying strategies. The present review aims to summarize new knowledge about the protective and detrimental aspects of neuroinflammation in AD and PD, providing an analysis on these developing prospects for targeted interventions toward slowing or stopping neurodegeneration.\n\nID: 42399494\nTitle: Unhealthy fat distribution as a sex-specific predictor of declining hippocampus insulin sensitivity.\nAbstract: Impairments in peripheral glucose metabolism and reduced brain insulin sensitivity are linked to an increased risk of both metabolic and neurodegenerative diseases. Brain insulin resistance represents a shared pathological mechanism underlying these disorders. Notably, hippocampal insulin responsiveness declines with age and differs between men and women. This study aimed to identify clinically relevant metabolic predictors of hippocampal insulin sensitivity in the context of age and sex. In 260 non-diabetic participants (165 women, mean BMI 29.7\u00a0\u00b1\u00a06.2\u2009kg/m2, mean age 44.2\u00a0\u00b1\u00a016.6 years), functional MRI was performed before and after intranasal insulin administration to assess hippocampal insulin response. Metabolic phenotyping comprised laboratory assessments including oral glucose tolerance tests, whole-body MRI and 1H-MRS. In addition, participants were assigned to high- and low-risk prediabetes clusters using the T\u00fcbingen risk cluster tool. Prediabetes was defined as impaired fasting glucose and/or impaired glucose tolerance and/or elevated HbA1c. We used linear regression models to select the most relevant predictors, including interactions with sex and age. Fasting plasma glucose levels predicted lower hippocampal insulin response with age independently of sex (estimate 0.533, p=0.016). Significant interactions were present between age, sex and body fat distribution (waist-to-hip ratio [WHR]: estimate 0.233, p=0.010; visceral adipose tissue [VAT]: estimate 0.007, p=0.013; intrahepatic lipid content [IHL]: estimate 0.003, p=0.010). In women, higher WHR, VAT and IHL were predictors of lower hippocampal insulin responsiveness with increasing age. These effects remained significant after adjusting for BMI. Postmenopausal women showed lower hippocampal insulin responsiveness with higher WHR and IHL (p<0.05), and women in high-risk T\u00fcbingen prediabetes clusters also showed lower hippocampal insulin responsiveness than men (sex \u00d7 cluster type: estimate 0.39, p=0.02). The hippocampal insulin response did not correlate with hippocampal volume (p>0.05). Unhealthy body fat distribution was a sex-dependent predictor for decreased hippocampal insulin sensitivity with increasing age. Older women with high abdominal fat and/or those assigned to high-risk clusters were most vulnerable to impaired insulin responsiveness in the hippocampus. These findings may contribute to explaining sex differences in the development of type 2 diabetes and neurodegenerative diseases.\n\nID: 42399329\nTitle: Microbial characterization of oral microbiome in patients with open-angle glaucoma.\nAbstract: Glaucoma is a progressive optic nerve degenerative disease that often leads to blindness. Local inflammatory responses in the retina and optic nerve are implicated in the pathology of glaucoma. In addition, microbial populations in other parts of the body have been linked to glaucoma. To explore the relationship between oral health and glaucoma we queried the FinnGen database (Risteys 10.0) to assess whether poor oral health carries an increased risk of subsequently developing primary open angle glaucoma (POAG). In a separate study, we also collected mouthwash samples and administered a questionnaire relating to oral health status to a cohort of participants enrolled in Diagnostic Innovations in Glaucoma Study (DIGS) that included 107 participants with glaucoma and 19 healthy non-glaucomatous controls. 16S sequencing was performed to characterize the number of bacteria species and total bacteria count of the samples. A significant association between having dental conditions affecting the teeth, gingiva, or periodontium and developing glaucoma after 1\u00a0year, 1-5\u00a0years, 5-15\u00a0years and cumulatively was detected in the FinnGen data, a population of 429,209 with at least 153,661 having a dental condition and 10,687 having POAG. Among the cohort of the DIGS ancillary study, the total bacterial count of the glaucoma group was significantly higher compared to that of controls (Mean\u2009\u00b1\u2009SD: 1.7\u2009\u00b1\u20091.4 and 0.9\u2009\u00b1\u20090.6, respectively, p\u2009<\u20090.03, two-sample t-test), while the species richness was significantly lower in glaucoma subjects compared to controls (p\u2009<\u20090.0005, Wilcoxon rank sum test). While the top taxa ordered by total abundance were similar between the two groups, mostly organisms associated with the commensal oral microbiome, there were some taxa linked with periodontal disease that were associated with glaucoma cases. However, the study was underpowered for the differences in top taxa between the glaucoma and non-glaucomatous control groups to achieve statistical significance (<\u20090.05) after adjusting for multiple comparison testing. A different bacterial abundance profile was detected between cases and controls by stepwise linear discriminant analysis. Inclusion of sleep apnea and the presence of cardiovascular disease as covariates in the analysis models did not significantly affect the results. Answers to the questionnaire about oral health and oral/dental history did not show a statistically significant difference between the two groups. The above findings suggest a potential link between oral health and glaucoma that may warrant further investigation.\n\nID: 42395216\nTitle: Human Exposure to Micro- and Nanoplastics and Their Potential Neurological Implications: A Systematic Review of Emerging Evidence.\nAbstract: The growing prevalence of micro- and nanoplastics (MNPs) in the environment elicits concerns about their possible impact on human neurological health. Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.\n\nID: 42381240\nTitle: Domino Effect of the Kynurenine Pathway: Systemic Homeostasis, Metabolic Crosstalk, and Therapeutic Potential.\nAbstract: The kynurenine (KYN) pathway (KP) is a central hub in tryptophan (Trp) metabolism, orchestrating immune regulation, neural signaling, and systemic energy homeostasis. Although KP dysregulation has been linked to multiple diseases, a unifying framework explaining how localized metabolic perturbations propagate across organs -a \"Domino Effect\"- is lacking. This review provides a comprehensive synthesis of KP's dual, context-dependent roles in immunity, neurodegeneration, cardiovascular disease, and gastrointestinal disorders. We critically evaluate the mechanistic basis of KYN as a master regulator via the aryl hydrocarbon receptor (AhR) and NAD+ biosynthesis, resolving controversies surrounding its pro-versus anti-inflammatory and pro-versus antitumorigenic functions. Key findings reveal that KP metabolites determine disease outcomes: KYNA/QA balance in the brain, inflammatory vascular remodeling in the heart, and host-microbiome crosstalk in the gut. We further assess therapeutic targeting of KP enzymes (IDO1, TDO2, KMO) and AhR, acknowledging both promising preclinical data and clinical translation challenges. Finally, we propose that future strategies must move beyond conventional enzyme inhibition to include upstream regulatory mechanisms. This review proposes a \"Domino Effect\" framework to provide new avenues for biomarker discovery, precision medicine, and structure-based drug design targeting the KP.\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: 42367844\nTitle: Cocaine-Enriched Oral Streptococcus parasanguinis Promotes Neuroimmune Dysfunction and Memory Impairment.\nAbstract: Chronic cocaine use is associated with neuroinflammation and cognitive dysfunction, but the underlying mechanisms remain unclear. We previously identified oral enrichment of Streptococcus parasanguinis (SP) and other species in individuals with cocaine use disorder (CUD), and here demonstrate that cocaine selectively enhanced SP growth in vitro . To investigate causality, antibiotic-pretreated wild-type C57BL/6 mice received chronic oral inoculation of SP, S. salivarius , Neisseria flavescens , or vehicle. SP-treated mice exhibited spatial memory impairment, increased brain IL-1\u03b2, and non-region-specific microglial activation, without detectable bacterial translocation into the brain. While amyloid-associated signaling changes were observed across all bacterial treatment groups, only SP induced cognitive deficits and neuroinflammation. Untargeted metabolomics identified distinct SP-associated oral-to-brain metabolite signatures, including cysteine S-sulfate (CSS) and altered histamine-associated metabolites. CSS and histamine induced neuroinflammatory and amyloid-associated responses in vitro . Together, these findings identify a cocaine-associated oral pathobiont that promotes neuroinflammation and neurodegeneration, suggesting a novel oral microbiome-brain axis in CUD.\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: 42362546\nTitle: Gut bacterial metabolite imidazole propionate potentiates Alzheimer's disease pathology.\nAbstract: The gut microbiome modulates metabolic and neurovascular processes implicated in Alzheimer's disease and related dementias (ADRD), but the underlying mechanisms remain unclear. Here, we identify the bacterial metabolite imidazole propionate (ImP) as a modifier of ADRD pathology. In a cohort of 1196 cognitively unimpaired adults, higher plasma ImP levels were associated with lower preclinical cognitive scores and biomarkers of ADRD, both cross-sectionally and longitudinally. Fecal metagenomic analysis linked putative ImP producers to ADRD phenotypes. Genome-wide integrative analysis revealed a locus on chromosome 12 associated with both plasma ImP levels and AD risk in humans, supporting a host genetic contribution to ImP regulation and a causal role of this metabolite in AD. In mice, chronic ImP administration exacerbated AD-like pathology. ImP impaired brain endothelial barrier and promoted tau hyperphosphorylation in primary neurons, an effect blocked by glycogen synthase kinase-3\u03b2 inhibition. Together, this study links ImP to hallmarks of neurodegeneration and suggests that targeting ImP may represent a potential strategy to modify ADRD risk.\n\nID: 42356271\nTitle: The Multiple Functions of Amyloid Beta in the Gut Epithelium and the Role of the Microbiota: A Study in the APP/PS1 Animal Model Subjected to Chronic Synbiotic Treatment.\nAbstract: Background:/ Over the past decade, increasing evidence has shifted attention from the brain to the gut microbiota (MB) as a source and site of systemic dissemination of amyloid-\u03b2 (A\u03b2), an APP derivative responsible for plaque formation in the brains of Alzheimer's disease (AD) patients. Furthermore, AD patients and APP/PS1 mice, a transgenic model of AD, exhibit dysbiosis. Objectives: Using APP/PS1 mice treated from 2 to 8 months of age, we studied ileal and colonic epithelial integrity, intestinal barrier (IB) integrity assessed through tight junction (TJ) protein expression, local immune system, the presence/increase in A\u03b2 expression in enterocytes, and the protective effects of synbiotic treatment. Methods: The tissue was stained with Periodic Acid-Schiff and Alcian Blue to evaluate epithelial morphology and mucus production, and immunohistochemistry was performed to assess TJs, immune markers, and A\u03b2 expression. Results: Our results demonstrate that colonic and ileal epithelium of 8-month-old APP/PS1 mice displays IB impairment in term of alterations of goblet cells staining and TJ protein expression and signs of immune involvement. The ileum was more severely affected, showing a reduced epithelial surface area, decreased lysozyme production, and fewer tuft cells. Long-term synbiotic treatment largely prevented APP/PS1 mouse changes and caused a significant increase in A\u03b2 expression in all treated mice. Conclusions: These findings support the belief in early intestinal involvement in AD and highlight the potential of the microbiota as a target for early intervention aimed at modifying the progression to neurodegeneration. Increased epithelial A\u03b2 labeling after treatment raises the possibility of intestinal management of A\u03b2, which requires further validation.\n\nID: 42356129\nTitle: \"Brain-First\" vs. \"Body-First\" PD: Definitions and Implications in Everyday Clinical Practice: A Systematic Review.\nAbstract: (1) Background and Objectives: Parkinson's disease's (PD) underlying pathophysiology still remains incompletely understood, with Braak's hypothesis of ASyn pathology propagation being the most widely accepted. Recently, a novel model has been introduced, proposing two distinct ASyn propagation pathways: a bottom-up trajectory termed Body-first PD, and a central nervous system (CNS)-initiated pathway termed Brain-first PD. This distinction introduces new perspectives in the PD literature landscape regarding diagnosis, prognostic factors and patient management. This study set out to systematically synthesize the current literature comparing Brain-first and Body-first PD, with a focus on clinical characteristics and disease progression, diagnostic biomarkers, and management approaches. (2) Materials and Methods: A systematic literature search was conducted in March 2025 using PubMed, Cochrane Library, DOAJ and Google Scholar. Human observational, diagnostic, and interventional studies published between 2019 and March 2025, including patients with de novo or early PD, were eligible. Pre-motor REM sleep behavioral disorder (RBD) was used as the primary differentiation criterion. Risk of bias was evaluated using the Joanna Briggs Institute (JBI) critical appraisal checklists. Results were synthesized using a narrative approach. (3) Results: Sixteen studies comprising 2107 PD patients met the inclusion criteria. Body-first PD was associated with a higher non-motor symptom (NMS) burden, faster disease progression, and a higher prevalence of cognitive impairment. Additionally, Body-first PD patients exhibited more widespread and symmetrical neurodegeneration, along with electrophysiological and metabolic differences. Distinct biomarker and microbiome profiles were also observed between subtypes. No eligible studies addressing management approaches were identified. (4) Conclusions: In conclusion, the available evidence suggests that Brain-first and Body-first PD may represent two distinct pathophysiological entities, a proposal with great significance for the diagnosis, prognosis and management of PD patients. However, the predominantly cross-sectional nature of the current literature limits causal inference. Future longitudinal and interventional studies are required to clarify the potential clinical implications of this subtype classification theory.\n\nID: 42356119\nTitle: The Role of Gut Microbiome in Mild Cognitive Impairment: A Twin Study.\nAbstract: Background and Objectives: Recent studies have revealed the potential roles of gut microbiota and microbial metabolites in influencing mild cognitive impairment (MCI) and Alzheimer's disease via the gut-brain axis. This relationship has not yet been investigated in monozygotic twin pairs, which represent an ideal model for minimizing genetic confounding. Materials and Methods: Seven twin pairs discordant for ACE and 15 for MoCA were enrolled. Stool samples were subjected to 16S ribosomal RNA-based microbiome analysis. Results: No significant differences in alpha or beta diversity were observed between MCI-discordant twin pairs at the genus or family level. The most robust finding was a significantly lower abundance of Lachnospiraceae in MCI-affected twins, identified independently by ANCOM-BC and LEfSe. Additional exploratory findings included higher abundances of Sutterella, Succinivibrio, Odoribacter, and Ruminococcus. However, several taxa showed opposing patterns between ACE- and MoCA-derived cohorts, highlighting the methodological impact of cognitive instrument selection. Conclusions: The convergent reduction of Lachnospiraceae across two independent analytical methods represents the most substantive finding. The remaining results are exploratory, limited by small sample size, restricted statistical power, and lack of availability to fully control for dietary habits, physical activity, and medication use. Validation in larger longitudinal twin cohorts with a standardized cognitive assessment is warranted.\n\nID: 42354855\nTitle: Postbiotics as Multifunctional Bioactives: Mechanistic Insights and Translational Applications in Host Physiology and Microbial Ecosystem Modulation.\nAbstract: Postbiotics are increasingly recognized as a predominant group of biotherapeutic agents sourced from the microbial secretome, offering functional benefits, while circumventing the safety concerns associated with the application of live microbial consortia. These microbial derivatives are emerging as promising approaches for tackling complex diseases, encompassing cancer, autoimmune diseases, and metabolic disorders, through modulation of host cell signalling pathways, including G protein-coupled receptors (GPCRs), the NF-\u03baB (Nuclear Factor Kappa B) pathway, and epigenetic regulatory pathways. Besides systemic effects, postbiotics may also have localized effects, such as epithelial regeneration, modulation of fibroblast functions, and control of collagen remodelling. Eventually, the scale-up in the production of postbiotics has initiated new avenues in improving sustainable agriculture and environmental biotechnology. This comprehensive review attempts to integrate mechanistic insights and translational applications, highlighting the therapeutic potential of postbiotics across biomedical and ecological domains.

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: 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: 42327194\nTitle: Gut bacterial Infection drives Parkinsonian pathology in LRRK2 G2019S Knock-in Mice.\nAbstract: The LRRK2 G2019S mutation is one of the most common genetic risk factors for Parkinson's disease (PD), yet LRRK2 G2019S knock-in (KI) mice rarely develop robust neurodegeneration under basal conditions, suggesting that additional environmental triggers are required for disease progression. Here, we established a clinically relevant gene-environment interaction mouse model of PD by subjecting LRRK2 G2019S KI mice to recurrent Citrobacter (C.) rodentium infection, a murine model of enteric bacterial inflammation. Repeated infection induced progressive PD-like phenotypes selectively in KI mice, including motor impairment, reduced locomotor activity, impaired motor coordination, selective nigrostriatal dopaminergic neurodegeneration, enhanced neuroinflammation, and pathological phosphorylated \u03b1-synuclein (p-\u03b1Syn) accumulation, whereas wild-type (WT) mice remained largely resistant. Mechanistically, infected KI mice developed markedly exacerbated colonic inflammation, epithelial barrier dysfunction, increased intestinal permeability, and enhanced inflammasome activation despite normal bacterial clearance, indicating that pathogenic LRRK2 signaling amplifies inflammatory responses rather than impairing antimicrobial defense. In parallel, recurrent infection induced pronounced intestinal p-\u03b1Syn accumulation and expansion of pathology beyond the epithelial layer in KI mice, supporting a gut-brain axis mechanism linking intestinal inflammation to neurodegeneration. Collectively, these findings demonstrate that the LRRK2 G2019S mutation functions as a sensitizing factor that cooperates with recurrent enteric inflammation to drive PD-related pathology. This study establishes a physiologically relevant LRRK2 G2019S gene-environment interaction mouse model that recapitulates key behavioral, neuropathological, and inflammatory features of PD.\n\nID: 42326513\nTitle: Interconnected influences of diet, gut microbiome, and metabolome on cognition across three metabolomics platforms.\nAbstract: Cognitive impairment is increasing with global aging, yet mechanisms linking diet, the gut microbiome, and metabolism to cognitive function remain unclear. To investigate a diet-microbiome-metabolome axis associated with cognition, we integrated fecal metagenomics, diet, and multi-platform plasma metabolomics in 505 older adults from four ADRCs. Several microbes broadly associated with circulating metabolites were also linked to multiple measures of cognitive performance. These taxa exhibited coordinated metabolic signatures, with cognition-positive microbes associated with antioxidant, lipid, and microbial-host co-metabolites, and microbes negatively associated with cognition were linked to inflammatory and aromatic amino acid-derived metabolites. Dietary patterns, particularly the Healthy Eating Index Greens and Beans component, were associated with microbial composition and metabolomic structure. Mediation analyses supported a diet-microbe-metabolite-cognition pathway, while metabolites remained associated with cognition after accounting for microbial features. These findings highlight the metabolome as a central integrator of diet, microbial activity, and cognitive function.\n\nID: 42324487\nTitle: Emerging directions in tauopathy research.\nAbstract: The Tau Global Conference 2025, hosted by the Alzheimer's Association, CurePSP, and the Rainwater Charitable Foundation, convened international experts from academia, industry, government, and philanthropy to explore advances and challenges in tauopathy research. The meeting highlighted progress across tau biology, including emerging models of tau regulation, degradation, and propagation; advances in biomarker development for the diagnosis and staging of tauopathies; and evolving therapeutic strategies targeting diverse aspects of tau pathophysiology. Discussions also emphasized the importance of cross-sector collaboration, and global initiatives to address disparities in tau research. This report synthesizes key insights from the conference and underscores the critical role of interdisciplinary, biomarker-driven, and globally inclusive approaches in accelerating the translation of tau research into effective clinical applications.\n\nID: 42321809\nTitle: Bacteria-derived glutarate mitigates Alzheimer's disease model pathology through autophagy-lysosomal pathway.\nAbstract: Probiotics exert neuroprotective effects against Alzheimer's disease (AD) by modulating gut-brain axis pathways, though disease-modifying therapies remain unavailable. Our study revealed that Escherichia coli (E. coli) strain HB101 ameliorated AD-related phenotypes in Caenorhabditis elegans\u200c (C. elegans) models, including learning deficits, neurodegeneration, and paralysis. Mechanistically, HB101 reduced amyloid-\u03b2 (A\u03b2) aggregation by enhancing lysosomal activity, autophagy, and mitochondrial/endoplasmic reticulum unfolded protein responses (UPRmt/UPRer). Specifically, HB101 activated UPRmt via atfs-1 and sphk-1, and UPRer through pek-1. Metabolomic screening pinpointed glutarate as a bioactive metabolite that mitigates AD-related pathology through lysosomal activation and autophagy promotion.\n\nID: 42319691\nTitle: A Comprehensive Review on the Microbial Signatures and Metabolic Mechanisms Underlying the Gut-Alzheimer's Disease Axis.\nAbstract: Alzheimer's disease (AD) is the most common form of dementia, driven by complex interactions among aging-related biological changes, neuronal degeneration, mitochondrial dysfunction, and environmental factors. Despite extensive research, effective disease-modifying therapies remain unavailable. Increasing evidence highlights the gut-brain axis as an important contributor to AD pathogenesis, particularly through amyloid-producing gut microbes that promote immune activation, neuroinflammation, and cerebral amyloid accumulation. This review summarizes current evidence linking gut microbiota (GM) dysbiosis to AD, focusing on microbial metabolites, neuroinflammatory pathways, and microbiota-targeted therapeutic strategies. A systematic analysis of experimental and clinical studies reveals that altered gut microbial composition is associated with systemic and neuroinflammation, blood-brain barrier dysfunction, oxidative stress, and neuronal damage. Key microbial metabolites, including short-chain fatty acids and indole derivatives, exhibit neuroprotective effects by regulating immune responses, maintaining barrier integrity, and supporting neuronal energy metabolism; disruption of these metabolites may accelerate neurodegeneration. Microbiota-based interventions such as probiotics, prebiotics, dietary modification, and fecal microbiota transplantation show beneficial effects in preclinical models by restoring microbial balance and reducing neuropathological features, although clinical evidence in humans remains limited. Overall, current findings support a contributory role of gut dysbiosis in AD and suggest that targeting the GM may offer a promising complementary strategy for disease modification and future therapeutic development.\n\nID: 42319427\nTitle: Disease modification in advanced Parkinson's disease: a review and roadmap for paving the way for next-generation interventions.\nAbstract: Parkinson's disease (PD) exhibits highly heterogeneous clinical trajectories, yet \"advanced PD\" (aPD) lacks a standardized definition. Current reliance on clinical milestones (e.g., motor fluctuations, cognitive decline) is limited by non-linear progression and the absence of objective measures. Although biomarkers like aggregated \u03b1-synuclein, MRI, and PET are under investigation, their correlation with clinical progression remains modest. Robust, reproducible endpoints are urgently needed to evaluate disease-modifying therapies across diverse phenotypes, accounting for genetic background, age of onset, co-pathologies, and motor/autonomic/cognitive domains. Given this complexity, single-target interventions are likely insufficient. We propose a multi-domain therapeutic framework for aPD that integrates: (A) simultaneous targeting of key pathological cascades, including \u03b1-synuclein aggregation, mitochondrial dysfunction, oxidative stress, proteostasis imbalance, neuroinflammation, and the gut-brain axis; (B) biology-driven patient stratification using emerging biomarkers to match subgroups with targeted interventions; and (C) systematic management of comorbidities and lifestyle factors, such as cardiovascular health and exercise, to enhance neuroresilience. Finally, advancing aPD care requires addressing systemic determinants, including global healthcare inequities, and prioritizing caregiver well-being. Mechanistically informed, patient-centered strategies that combine multi-target therapies with precision stratification and holistic support will be essential to modify disease progression and improve long-term outcomes.\n\nID: 42317872\nTitle: Nutrients and bioactive compounds as modifiers of neurodegenerative trajectories: molecular mechanisms, translational barriers, and precision nutrition.\nAbstract: The Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS) are a growing health burden across the world with minimal disease-modifying treatment and therapy. It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.\n\nID: 42309987\nTitle: Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications.\nAbstract: The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high-impact studies using ADNI data or biospecimens from 2023 to mid-2025 to clarify mechanisms of Alzheimer's disease (AD) progression. Studies describe impairment of glymphatic clearance and the impact of cerebral small vessel disease, trajectories of amyloid beta and tau deposition, inflammation, metabolic disturbances, synaptic dysfunction, and neurodegeneration, leading to cognitive impairment and neuropsychiatric symptoms. Multifactorial contributions from genetic and epigenetic influences, co-pathologies and comorbidities, and mechanisms of resilience modulate disease progression. Finally, heterogeneity of clinical presentation and disease course is described in the context of multiple contributing factors, highlighting the complexity of AD. By integrating imaging, fluid biomarkers, genetics, and clinical measures, ADNI provides a comprehensive research dataset for unraveling mechanisms underlying AD progression.\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=======================================================\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.

Acupuncture, a multi-target holistic non-pharmacological intervention, shows unique clinical advantages. This review provides the first systematic synthesis of the central neurobiological mechanisms underlying acupuncture's therapeutic effects on PSD. The identified mechanisms include promoting neuroplasticity via the BDNF/TrkB pathway and rebalancing neurotransmitter systems (monoamines and glutamate/GABA). Additionally, acupuncture inhibits microglial activation and TLR4/NF-\u03baB/NLRP3-driven neuroinflammation, restores mitochondrial homeostasis through AMPK-dependent autophagy, and modulates the gut microbiota-brain axis.

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\"Microbiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\"\n\nThe evidence provided confirms that microbiota-derived acetate, often facilitated by specific probiotic strains, exerts neuroprotective effects under hypoxic conditions. Multiple studies consistently demonstrate that acetate supplementation suppresses neuroinflammation (reducing pro-inflammatory cytokines) and protects against cognitive decline through the restoration of BDNF-related pathways.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis confirms that the modulation of the gut microbiota to increase short-chain fatty acid (SCFA) production\u2014specifically acetate\u2014serves as a robust therapeutic intervention against hypoxia-induced neuroinflammation and cognitive impairment. Evidence establishes that acetate acts as a downstream mediator for beneficial gut bacteria, effectively mitigating hippocampal inflammation and protecting neuronal integrity, often through the subsequent upregulation of BDNF and related neuroplasticity signaling.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe gut-brain axis functions as a critical nexus for neuroprotection, where microbial metabolites serve as key signaling molecules. Chronic intermittent hypoxia (CIH) disrupts this homeostasis, leading to gut dysbiosis, systemic inflammation, and cognitive dysfunction. Research indicates that specific bacterial strains, such as *Bifidobacterium pseudolongum*, function to restore acetate levels. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells.\n\nThe mechanism by which acetate mitigates injury involves the downregulation of neuroinflammatory mediators and the preservation of synaptic function. In particular, the restoration of gut microbiota in hypoxic or aging models consistently correlates with higher BDNF levels. Evidence demonstrates that the gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation. This restoration of systemic and local metabolic homeostasis is essential for promoting BDNF-mediated neuroplasticity.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Acetate is not merely a metabolic byproduct but a specific regulator of cGAS-STING-mediated PANoptosis.\n* The effect of acetate can be bypassed by direct enteral supplementation, confirming the causal link between acetate depletion and neurocognitive vulnerability.\n* High-altitude adaptation and hypobaric hypoxia create unique metabolic demands that probiotics can address via \"dual-track\" metabolic reprogramming.\n* The interaction between gut microbial SCFA production and hippocampal BDNF signaling is conserved across multiple distinct stress models (hypoxia, alcohol consumption, and aging).\n* Acetate's role in the gut-brain axis is inherently linked to lipid metabolism, suggesting that neuroprotective effects involve more than just neurotransmitter modulation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice. It reshaped gut microbial structures, enriched beneficial bacteria taxa such as Dubosiella, [Eubacterium]_coprostanoligenes_group, and Allobaculum, and increased SCFA levels. FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance. In addition, FDO upregulated BDNF, PSD-95, and SYN expression and reduced corticosterone (CORT) levels. Compared with DO, FDO showed more pronounced regulatory effects.

Microbiome-derived metabolites have been increasingly associated with disease onset, progression, and therapeutic targets in neurodegenerative disorders. Exploring the diagnostic and therapeutic implications of gut microbiome-derived biomarkers is critical to advancing our understanding and management of neurodegeneration. We systematically reviewed both clinical and preclinical studies published from 2010 to 2025. Studies examining gut microbiota composition, microbial-derived metabolites, or therapeutic interventions targeting the gut microbiome were included. Identification of gut microbiome alterations, discovery of microbial or metabolite-based biomarkers, association with disease onset or progression, and/or therapeutic effects on cognitive, neurological, or inflammatory outcomes were evaluated. Short-chain fatty acids(SCFAs) such as butyrate and acetate were found to be noninvasive biomarkers in patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and Parkinson's disease (PD). Lower SCFA levels correlated with cognitive decline. Diagnostic accuracy improved when SCFA combinations were used, with AUCs ranging from 0.75 to 0.87. Trimethylamine N-oxide(TMAO) levels showed inconsistent associations, with both elevated and reduced levels linked to disease risk. Therapeutic approaches targeting gut microbiota, including probiotics, prebiotics, dietary changes, and fecal microbiota transplantation, demonstrated cognitive benefits and modulation of gut-brain signaling pathways. Overall, gut-derived biomarkers offer a promising avenue for early diagnosis and novel therapeutic approaches in AD and PD, while acknowledging that evidence in other neurodegenerative diseases remains limited through modulation of the gut-brain axis."

To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting. Treatment with BC99 was associated with alleviation of CUMS-induced depressive-like behaviors, increased butyrate levels, reduced neuroinflammation (IL-1\u03b2, IL-6, LPS, and IL-4), and restored hippocampal BDNF levels. BC99 also enriched butyrate-producing bacterial taxa (e.g., Lactobacillus, Bifidobacterium, Faecalibaculum) and normalized tryptophan and sphingolipid metabolism. Notably, sodium butyrate alone recapitulated several of the behavioral and anti-inflammatory effects observed with BC99 and, as shown by Western blot, partially restored hippocampal BDNF/TrkB/CREB signaling, which was impaired in CUMS rats. Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression."

Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the \"Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Function\" axis. Consistent physical exercise alters the gut microbiota, enhancing Short-Chain Fatty Acid (SCFA)-producing populations, which is associated with markedly elevated bioavailability of key metabolites (acetate, propionate, and butyrate). Rather than detailing exhaustive molecular pathways here, we emphasize that these SCFAs facilitate gut-brain communication through multiple synergistic routes, including receptor-mediated neuroendocrine signaling, epigenetic modulation of neuroplasticity, and the attenuation of systemic neuroinflammation. Current human observational and interventional data strongly support an associative link between exercise-induced SCFA fluctuations and improved mental health outcomes. Crucially, we propose the novel \"Exercise \u00d7 Fiber Synergy\" hypothesis: exercise primes the intestinal ecological niche for efficient substrate-utilizing bacteria, while adequate fermentable dietary fiber provides the necessary raw materials. Synergistically, this combination optimizes SCFA production to maximize cognitive and emotional benefits. To transition this framework into clinical practice, future research must prioritize 2 \u00d7 2 factorial designs (Exercise \u00d7 Fiber) with dynamic kinetic measurements, paving the way for microbial phenotype-oriented precision exercise and personalized nutritional interventions to enhance public mental health."

We show that diet rich in acetylated high-amylose maize starch shifts the gut microbiome to favor acetate-producing bacteria, increasing systemic acetate levels and reducing pain hypersensitivity. This is associated with reduced spinal microglia activation and anti-inflammatory cytokine gene expression, with elevated IL-10 mRNA in the DRG and IL-10, IL-2, and IL-6 in the spinal cord. Electrophysiologically, we observe reduced hyperexcitability in the dorsal horn and increased inhibitory activity. The mechanism driving this change involves reduced prostaglandin-E2 (PGE2)-mediated suppression of glycinergic inhibition, a direct consequence of maintaining microglia in quiescent state. These findings link dietary metabolites to reduced fibromyalgia-like pathology and identify targeted nutrition as a potential disease-modifying therapy for chronic pain."

Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin.

Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium longum 1714 have been associated with neuroactive effects, yet the molecular mechanisms linking microbial genomic potential to host neuronal responses remain poorly defined. This study aimed to integrate microbial genomics, neurotranscriptomics, and in vitro validation to unravel the neuromodulatory effects of L. rhamnosus GG and B. longum 1714. Whole-genome functional annotation, metabolic pathway prediction, and biosynthetic gene cluster analysis were performed to identify neuroactive potential. Neuronal RNA-seq datasets (n = 3 biological replicates per condition) were analyzed using differential expression, WGCNA, and GSEA to capture transcriptomic responses. Multi-omics integration (CCA, DIABLO, SPIEC-EASI) linked microbial pathways with neuronal gene modules. In vitro assays using SH-SY5Y and iPSC-derived neurons validated predictions through measurements of cell viability, oxidative stress, neurotransmitter release (ELISA), qPCR of synaptic and inflammatory genes, and extracellular vesicle characterization including EV transcript profiling. Genomic analysis revealed that L. rhamnosus GG was enriched in \u03b3-aminobutyric acid (GABA) and SCFA pathways, while B. longum 1714 carried tryptophan-indole metabolism genes. Transcriptomic profiling demonstrated upregulation of synaptic genes (BDNF, SYN1), showed upregulation of synaptic genes (BDNF, SYN1), serotonergic transporters (SLC6A4, TPH2), and suppression of inflammatory mediators (IL-6, TNF-\u03b1). Integration analyses identified two major subnetworks: a \"neurotransmission module\" driven by L. rhamnosus GG and a \"serotonin-immune module\" driven by B. longum 1714. In vitro validation confirmed increased GABA (1.7-fold) and serotonin (1.5-fold) release, reduced ROS (-18 to -22%), and EV transcript enrichment for synaptic and anti-inflammatory markers. This multi-omics study demonstrates mechanistic evidence that probiotics exert complementary neuromodulatory effects: L. rhamnosus GG primarily enhances GABAergic and SCFA-mediated synaptic pathways, whereas B. longum 1714 regulates the tryptophan-serotonin-immune axis. Together, these findings support the therapeutic potential of precision probiotics for neurological health and establish a systems-level framework for probing host-microbe interactions."

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease."

However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases."

Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA."

There are limited therapeutic options for TBI, and supportive care remains the mainstay of treatment. Our previously published data demonstrate that post-TBI fecal microbiome transplantation (FMT) can reverse TBI-induced depletion of commensal bacteria, preserve white matter connectivity and neurocognition, and decrease cortical volume loss in mice after TBI. We hypothesized that post-TBI supplementation with short-chain fatty acids (SCFAs), metabolites of commensal gut bacteria, would attenuate neurologic injury after TBI in mice. 14-week-old male C57BL/6 mice ( n = 52) underwent TBI via a controlled cortical impact versus sham injury. Post-TBI, each group was treated with the SCFAs acetate, butyrate, and propionate versus a molar-equivalent sodium chloride vehicle via free access to drinking water for 4 weeks post-TBI. The stool was collected 3 days pre- and 60 days post-TBI to assess the gut microbial community structure via 16s ribosomal RNA gene amplicon sequencing. Neurocognitive testing was performed with open-field and zero-maze testing. Ventricular volume and white matter connectivity were measured with 3D, contrast-enhanced magnetic resonance imaging. Lastly, the transcriptional response of microglia was assessed with single-cell RNA sequencing (scRNAseq). SCFA supplementation decreased TBI-induced microbial loss, attenuated ventricular volume loss, preserved white matter connectivity, and altered the transcriptional profile of microglia after TBI. Post-TBI SCFA supplementation preserved the abundance of the butyrate-producing taxa Firmicutes, Clostridia, Ruminoccacaceae , and Peptoccacaceae ( P\u2009=\u2009 0.01). SCFA also reduced the TBI-induced increase in Clostridiales and Bacteroidales compared with the salt vehicle group ( P\u2009=\u2009 0.05). We also observed the preservation of non-TBI murine anxiety-like behavior in SCFA-treated TBI mice compared with vehicle-treated TBI mice in the zero-maze (152.3 \u2009 \u00b1 \u2009 101.8\u2009cm vs. 147.5 \u2009 \u00b1 \u2009 60.0\u2009cm, P\u2009=\u2009 0.006). These results were recapitulated with open-field testing (11.7 \u2009 \u00b1 \u2009 3%-time in the center in SCFA-treated TBI mice vs. 15.0 \u2009 \u00b1 \u2009 6%-time in the center of the field in vehicle-treated mice; P\u2009=\u2009 0.002). Lastly, we observed upregulation of transcripts for the neuroprotective heat-shock family of proteins and downregulation of neurodegeneration-associated transcripts, indicating an overall neuroprotective phenotype in microglia after SCFA supplementation post-TBI. We hypothesized that SCFA supplementation would attenuate neurologic injury after TBI in mice. SCFA supplementation attenuated neurocognitive deficits, reduced cortical volume loss, preserved white matter connectivity, and decreased neuroinflammation. These benefits may result from the direct replacement of SCFAs. However, there may also be secondary mechanisms related to commensal refeeding of butyrate-producing bacteria within the gut microbial community, a neuroprotective heat-shock response, and a decrease in the expression of genes associated with neurodegeneration. The current study highlights the role of SCFAs in microbiome homeostasis and the potential of dietary intervention as a novel therapy in TBI."

It induces depression-like behaviors primarily by disrupting hypothalamic-pituitary-adrenal (HPA) axis homeostasis and impairing hippocampal synaptic plasticity. Flavonoids are abundant in human diet and possess significant neuroprotective potential. We screened a library of 339 flavonoid compounds. Daidzein (DAI) was identified as the lead compound. Subsequently, in rats subjected to chronic restraint stress (CRS), DAI administration effectively ameliorated depression-like behaviors, and attenuated hippocampal histopathological damage. Network pharmacology and molecular docking analyses suggested that ERK-related signaling may be involved in the protective effects of DAI, and molecular dynamics simulations supported the stability of the DAI-ERK2 complex. Furthermore, DAI activated the ERK/CREB/BDNF signaling cascade, an effect that was partially reversed by ERK inhibitor intervention. Notably, DAI also enhanced dendritic complexity and spine density in hippocampus. In summary, our study demonstrates that DAI alleviates stress-induced synaptic plasticity damage through the ERK/CREB/BDNF signaling pathway."

Enavogliflozin, a novel sodium-glucose cotransporter 2 (SGLT2) inhibitor, has recently been demonstrated to exert neuroprotective effects. However, whether enavogliflozin can ameliorate motor behavioral deficits in Parkinson's disease currently remains unclear. To this end, this study aimed to investigate the neuroprotective effects of enavogliflozin on Parkinson's disease and explore its underlying molecular mechanisms. We established a Parkinson's disease model using rotenone-induced C57BL/6 mice (1.5\u202fmg/kg/d, 3 weeks, i.p.) to investigate the neuropharmacological modulation effects of enavogliflozin treatment (0.1 and 1\u202fmg/kg/d, 3 weeks, p.o., 2\u202fh after rotenone injection) on Parkinson's disease from the perspectives of motor behavioral evaluation, pathological changes, oxidative stress, neuroinflammation, and SIRT1/PINK1/Parkin signaling pathways in specific brain regions. The results revealed that enavogliflozin alleviated neuropathological alterations of the substantia nigra, upregulated tyrosine hydroxylase and dopamine transporter expression in nigrostriatal dopaminergic neurons, and improved motor behavioral deficits. Administration of enavogliflozin further significantly reduced the levels of inflammatory cytokines (IL-6 and TNF-\u03b1), microglial activation, and oxidative damage in rotenone-induced Parkinson's disease mice. Moreover, we found that enavogliflozin activated PINK1/Parkin-mediated mitophagy by SIRT1 signaling pathway. In conclusion, enavogliflozin ameliorates motor dysfunction in rotenone-induced Parkinson's disease mice by attenuating oxidative stress, inhibiting neuroinflammation, and activating SIRT1/PINK1/Parkin pathway. These findings support a neuroprotective and preventive role for enavogliflozin in Parkinson's disease."

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy."

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement.

Target-network analysis identified 79 shared targets associated with curcumin and intestinal inflammation. In vitro, macrophages were treated with curcumin at 40 and 80 \u03bcM before stimulation with lipopolysaccharide or Salmonella Enteritidis infection. In vivo, mice were challenged with S.

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\"Microbiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\"\n\nThe evidence provided confirms that microbiota-derived acetate, often modulated by probiotics or prebiotics, is associated with the alleviation of hypoxia-induced (including chronic intermittent hypoxia and hypobaric hypoxia) neuroinflammation and cognitive impairment. Mechanisms involve the restoration of BDNF expression and modulation of neuroinflammatory pathways, such as the inhibition of microglial activation. While acetate is frequently cited as a mediator, the causal chain involving acetate specifically as the sole upstream trigger for BDNF upregulation in all hypoxia models requires careful interpretation of the cited studies.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe hypothesis that gut microbiota-derived acetate mitigates hypoxia-related neurodegeneration and neuroinflammation through BDNF upregulation is supported by current preclinical evidence. Specifically, hypoxia induces gut dysbiosis, leading to diminished acetate production, while acetate supplementation or probiotic-mediated acetate restoration suppresses microglial activation and rescues BDNF levels to improve cognitive outcomes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurological resilience is tightly linked to the integrity of the gut-brain axis. Hypoxia, whether in the form of hypobaric conditions or chronic intermittent hypoxia, disrupts gut ecological balance, leading to systemic and central inflammation. Recent studies indicate that this hypoxic insult results in a marked depletion of short-chain fatty acids (SCFAs), with acetate frequently identified as a critical metabolite. \n\nMechanistically, the restoration of acetate levels\u2014either through targeted bacterial supplementation or direct administration\u2014acts as a neuroprotective signal. Acetate functions as a substrate for metabolic homeostasis and modulates histone deacetylase (HDAC) activity, influencing gene expression profiles associated with synaptic plasticity. The upregulation of brain-derived neurotrophic factor (BDNF) is a convergent downstream event across multiple models of neurodegeneration, where acetate-dependent restoration of metabolic cross-feeding or direct signaling mitigates neuroinflammatory cytokines like TNF-\u03b1 and IL-1\u03b2. This pathway facilitates the recovery of neuronal function following hypoxic challenges.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Microbiota-derived acetate can function as a \"dual-track\" regulator, restoring gut ecological balance while engaging in stress-adapted metabolic reprogramming.\n* Hypoxia-induced cognitive impairment is significantly linked to a reduction in the abundance of specific beneficial taxa like *Bifidobacterium pseudolongum*.\n* The effects of acetate are not limited to metabolic support but extend to direct suppression of hippocampal microglial activation and neuronal PANoptosis.\n* Dietary intervention, such as the use of acetylated starches, provides a sustained microbial source of acetate that can attenuate long-term neurological deficits.\n* Acetate restoration functions as a therapeutic node by modulating Class I histone deacetylases, thereby altering the chromatin landscape to favor neuroplasticity.\n* Preclinical models consistently demonstrate that acetate supplementation reproduces the anti-neuroinflammatory effects observed with probiotic administration.\n* The systemic-to-central axis is highly sensitive to acetate concentrations, influencing the activation state of innate immune cells in the hippocampus.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n\nID: 42422212\nTitle: Opposite regulatory effects of Blautia massiliensis and Blautia faecis on cognitive function, microglia and metabolite acetic acid in mice.\nAbstract: Cognitive impairment is a significant health problem worldwide, closely associated with the status of gut microbiota. Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis. Consequently, our findings indicate that Blautia massiliensis enhances cognitive function whereas Blautia faecis impairs it, and we speculate that differential acetate production may contribute to these opposing effects.\n\nID: 42354990\nTitle: The Gut-Brain-Muscle Axis: Microbial Regulation of Neuromuscular Aging and Cognitive Frailty.\nAbstract: Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, has emerged as a major challenge in aging populations and is closely linked to sarcopenia, neurodegeneration, and chronic inflammation. Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity.\n\nID: 42354205\nTitle: Fermented Dendrobium officinale Ameliorates Sleep Deprivation-Induced Depressive-like Behaviors by Attenuating Neuroinflammation and Restoring 5-HT Synthesis via the Gut-Brain Axis.\nAbstract: Chronic sleep deprivation (SD) disrupts gut-brain axis (GBA) homeostasis and is closely associated with gut microbiota dysbiosis, neuroinflammation, and depression-like behaviors. This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice. It reshaped gut microbial structures, enriched beneficial bacteria taxa such as Dubosiella, [Eubacterium]_coprostanoligenes_group, and Allobaculum, and increased SCFA levels. FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance. In addition, FDO upregulated BDNF, PSD-95, and SYN expression and reduced corticosterone (CORT) levels. Compared with DO, FDO showed more pronounced regulatory effects. Correlation analysis suggested that 5-HT may link gut microbial metabolites, inflammation, and synaptic plasticity. In summary, these findings support FDO as a potential GBA-targeted functional food for SD-related depressive-like behaviors.\n\nID: 42322241\nTitle: Gut-Brain Axis Modulation by Short-Chain Fatty Acids Exerts Disease-Modifying Effects in a Murine Model of Drug-Resistant Epilepsy.\nAbstract: Drug-resistant epilepsy (DRE) remains a clinical challenge, as therapies modifying disease trajectory are lacking. Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short-chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti-inflammatory properties. Clinical studies show that people with DRE exhibit gut microbiota alterations that may impair fecal SCFAs production. Here, we investigated whether supplementation of SCFAs confers disease-modifying effects in a preclinical model of DRE. Adult male mice were subjected to status epilepticus (SE) and subsequently treated with a balanced mixture of acetate, propionate, and butyrate, or vehicle. Seizure frequency and temporal progression were monitored for 70 days by electroencephalography (EEG). At the study end point, cognitive performance, brain and gut histopathology, and neuroinflammation were assessed, together with metabolomic profiling of feces and blood. Brain SCFA levels and receptor expression were also analyzed in mice and in brain tissue from individuals with DRE. SCFA supplementation reduced the proportion of mice exhibiting a progressive phenotype and decreased the overall progression index (PI) 3-fold, without significantly altering overall daily seizure frequency. Treatment reduced seizure clustering, improved cognitive deficits, restored hippocampal and intestinal alterations, and partially normalized cerebral SCFAs levels. Metabolomic profiling in epileptic mice and analysis of human epilepsy brain tissue support a mechanistic contribution of gut-brain axis dysfunction to disease progression. These findings identify SCFAs supplementation as a therapeutic strategy capable of modifying disease trajectory in experimental DRE, with clear translational relevance.

Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction. Targeting B.p and acetate may offer a promising therapeutic strategy for neuroprotection in OSA.\n\nID: 42237711\nTitle: Gut Microbiome-Sleep Crosstalk: Mechanistic Pathways, Dysbiosis Signatures, and Microbiome-Based Interventions.\nAbstract: This review examines the bidirectional relationship between sleep regulation and the gut microbiome within the gut-brain axis, with particular attention to mechanistic pathways, disorder-associated dysbiosis patterns, and microbiome-targeted interventions in insomnia, obstructive sleep apnea, circadian disruption, and sleep loss-related states. We critically synthesized evidence from both human and preclinical studies, focusing on microbial metabolites, neuroimmune and neuroendocrine signaling, circadian regulation, and intervention-based approaches. Rather than only summarizing individual studies, we aimed to distinguish associative human findings from mechanistic evidence derived mainly from animal models. Current evidence supports a bidirectional link between sleep and the gut microbiome. Microbiota-derived metabolites, particularly short-chain fatty acids, tryptophan-related metabolites, and gamma-aminobutyric acid, appear to influence sleep homeostasis through effects on intestinal barrier integrity, inflammatory tone, stress-axis regulation, and central signaling pathways. Across sleep disorders, recurrent microbial patterns include reduced abundance of potentially beneficial taxa such as Bifidobacterium and Faecalibacterium and enrichment of pro-inflammatory or stress-associated taxa, although these signatures are not yet fully consistent across cohorts or disorders. In humans, most data remain observational and support association rather than causation, whereas stronger mechanistic support comes from experimental models of sleep deprivation, intermittent hypoxia, and microbiota transfer. Early intervention studies suggest that selected probiotics, prebiotics, dietary modulation, and related microbiome-directed strategies may improve sleep-related outcomes, but the magnitude and reproducibility of these effects remain uncertain. The gut microbiome represents a promising mechanistic and therapeutic target in sleep medicine, but clinical translation is still constrained by heterogeneity in microbiome profiling, sleep phenotyping, intervention design, and strain-specific effects. Future work should prioritize longitudinal human studies, standardized outcome measures, and mechanistically informed trials capable of identifying clinically actionable and biologically credible microbiome signatures.\n\nID: 42227044\nTitle: The gut-brain axis in Alzheimer's and Parkinson's diseases: a systematic review of microbiota-derived biomarkers and novel therapeutic approaches.\nAbstract: The altered gut microbiota substantially impacts the onset and progression of Alzheimer's disease (AD) and Parkinson's disease (PD), the two most widely studied neurodegenerative conditions. Microbiome-derived metabolites have been increasingly associated with disease onset, progression, and therapeutic targets in neurodegenerative disorders. Exploring the diagnostic and therapeutic implications of gut microbiome-derived biomarkers is critical to advancing our understanding and management of neurodegeneration. We systematically reviewed both clinical and preclinical studies published from 2010 to 2025. Studies examining gut microbiota composition, microbial-derived metabolites, or therapeutic interventions targeting the gut microbiome were included. Identification of gut microbiome alterations, discovery of microbial or metabolite-based biomarkers, association with disease onset or progression, and/or therapeutic effects on cognitive, neurological, or inflammatory outcomes were evaluated. Short-chain fatty acids(SCFAs) such as butyrate and acetate were found to be noninvasive biomarkers in patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and Parkinson's disease (PD). Lower SCFA levels correlated with cognitive decline. Diagnostic accuracy improved when SCFA combinations were used, with AUCs ranging from 0.75 to 0.87. Trimethylamine N-oxide(TMAO) levels showed inconsistent associations, with both elevated and reduced levels linked to disease risk. Therapeutic approaches targeting gut microbiota, including probiotics, prebiotics, dietary changes, and fecal microbiota transplantation, demonstrated cognitive benefits and modulation of gut-brain signaling pathways. Overall, gut-derived biomarkers offer a promising avenue for early diagnosis and novel therapeutic approaches in AD and PD, while acknowledging that evidence in other neurodegenerative diseases remains limited through modulation of the gut-brain axis.\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: 42123660\nTitle: Butyrate Is Associated with the Antidepressant Effects of Weizmannia coagulans BC99: Functional Similarity of a Microbial Metabolite in the Microbiota-Gut-Brain Axis.\nAbstract: Butyrate, a short-chain fatty acid derived from the gut microbiota, has been linked to depression through correlational studies; however, whether it might act as a sufficient downstream mediator of the antidepressant effects of a probiotic remains poorly understood. To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting. Treatment with BC99 was associated with alleviation of CUMS-induced depressive-like behaviors, increased butyrate levels, reduced neuroinflammation (IL-1\u03b2, IL-6, LPS, and IL-4), and restored hippocampal BDNF levels. BC99 also enriched butyrate-producing bacterial taxa (e.g., Lactobacillus, Bifidobacterium, Faecalibaculum) and normalized tryptophan and sphingolipid metabolism. Notably, sodium butyrate alone recapitulated several of the behavioral and anti-inflammatory effects observed with BC99 and, as shown by Western blot, partially restored hippocampal BDNF/TrkB/CREB signaling, which was impaired in CUMS rats. Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression.\n\nID: 42069333\nTitle: BBB permeable selective HDAC3 inhibitor SP108 restores hippocampal plasticity and learning in a MAM-induced model of schizophrenia.\nAbstract: Schizophrenia is a complex neurodevelopmental disorder with cognitive impairment being one of the core features that remains largely unresponsive to current antipsychotic treatments. Histone deacetylase 3 (HDAC3), a negative regulator of memory and synaptic plasticity, has been implicated in neurodegenerative conditions, but its role remains underexplored in psychosis. Here, we hypothesized that aberrant HDAC3 activity contributes to hippocampal dysfunction and learning deficits in schizophrenia. Pregnant SD rats were administered methylazoxymethanol (MAM; 20\u202fmg/kg) and vehicle on GD 17. We characterized the pharmacokinetic profile of selective HDAC3 inhibitor, SP108, to ensure adequate BBB penetration and systemic exposure. Next, adult male offspring were administered SP108 (25\u202fmg/kg, i.p.) and vehicle every day for 3 weeks, followed by behavioral analysis. The MAM-exposed group showed schizophrenia-like behavioral patterns with increased hippocampal HDAC3 expression and activity. HDAC3 inhibitor treatment selectively ameliorated avoidance learning and MK801-induced hyperlocomotion. At the molecular level, HDAC3 inhibition elevated hippocampal H3K9 acetylation and increased the expression of synaptic plasticity markers BDNF and PSD95. To establish a neurodevelopmental link, HDAC3 knockdown was performed in differentiating neurons from mouse embryonic stem cells (mESCs) exposed to MAM at the early differentiating phase in vitro. HDAC3 knockdown in MAM-exposed differentiating neurons enhanced MAP2 intensity and neurite length with improved levels of MAP2, NeuN, TUBB3 (neuronal differentiation and maturation markers), BDNF, and PSD95 (neuroplasticity markers). Collectively, these findings identify HDAC3 as an important regulator of hippocampal dysfunction and cognitive impairment in a schizophrenia-like preclinical model, highlighting its potential to augment the therapeutic outcomes beyond current antipsychotic treatments.\n\nID: 42052400\nTitle: Exercise prescription for mood and cognition: targeting the microbiota-gut-brain axis through short-chain fatty acids.\nAbstract: Scientific study has extensively corroborated the advantageous impacts of exercise on mood, cognitive function, and stress resilience. Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the \"Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Function\" axis. Consistent physical exercise alters the gut microbiota, enhancing Short-Chain Fatty Acid (SCFA)-producing populations, which is associated with markedly elevated bioavailability of key metabolites (acetate, propionate, and butyrate). Rather than detailing exhaustive molecular pathways here, we emphasize that these SCFAs facilitate gut-brain communication through multiple synergistic routes, including receptor-mediated neuroendocrine signaling, epigenetic modulation of neuroplasticity, and the attenuation of systemic neuroinflammation. Current human observational and interventional data strongly support an associative link between exercise-induced SCFA fluctuations and improved mental health outcomes. Crucially, we propose the novel \"Exercise \u00d7 Fiber Synergy\" hypothesis: exercise primes the intestinal ecological niche for efficient substrate-utilizing bacteria, while adequate fermentable dietary fiber provides the necessary raw materials. Synergistically, this combination optimizes SCFA production to maximize cognitive and emotional benefits. To transition this framework into clinical practice, future research must prioritize 2 \u00d7 2 factorial designs (Exercise \u00d7 Fiber) with dynamic kinetic measurements, paving the way for microbial phenotype-oriented precision exercise and personalized nutritional interventions to enhance public mental health.\n\nID: 42006347\nTitle: Microbiome-derived metabolites alleviate chronic pain in a reserpine-induced model of fibromyalgia.\nAbstract: Fibromyalgia is a chronic pain disorder driven by central sensitization and neuroinflammation, increasingly linked to gut-brain axis dysfunction. Here, we delineate a gut-to-CNS axis for pain modulation, demonstrating that an acetate-producing diet alleviates reserpine-induced-fibromyalgia in a rodent model. We show that diet rich in acetylated high-amylose maize starch shifts the gut microbiome to favor acetate-producing bacteria, increasing systemic acetate levels and reducing pain hypersensitivity. This is associated with reduced spinal microglia activation and anti-inflammatory cytokine gene expression, with elevated IL-10 mRNA in the DRG and IL-10, IL-2, and IL-6 in the spinal cord. Electrophysiologically, we observe reduced hyperexcitability in the dorsal horn and increased inhibitory activity. The mechanism driving this change involves reduced prostaglandin-E2 (PGE2)-mediated suppression of glycinergic inhibition, a direct consequence of maintaining microglia in quiescent state. These findings link dietary metabolites to reduced fibromyalgia-like pathology and identify targeted nutrition as a potential disease-modifying therapy for chronic pain.\n\nID: 41935130\nTitle: Protective effects of enteral acetate supplementation against brain injury in a rat model of necrotizing enterocolitis.\nAbstract: Necrotizing enterocolitis (NEC) is a severe gastrointestinal disease in preterm infants, often leading to brain injury. The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants.\n\nID: 41926238\nTitle: 2'-Fucosyllactose Alleviates Metabolic Hypertension in Mice via Gut Microbiota Modulation and Involvement of the LPS/TLR4 Signaling.\nAbstract: 2'-Fucosyllactose (2'-FL) shows promise in ameliorating metabolic disorders. However, the role of 2'-FL in metabolic hypertension (MH) remains unclear. This study aimed to evaluate the effects of 2'-FL on MH and explore its underlying mechanisms. 2'-FL treatment (1000 mg/kg) reduced systolic blood pressure (SBP) by 16.6% and alleviated dyslipidemia, microglial activation, and neuroinflammation in MH mice. 2'-FL markedly increased short-chain fatty acids (SCFAs)-producing beneficial bacteria, e.g., Akkermansia and Bifidobacterium by 3.9-fold and 19.5-fold, accompanied by increased fecal acetate and butyrate. Notably, the benefits of 2'-FL for MH were transferable via fecal microbiota transplantation (FMT). Particularly, 2'-FL-mediated attenuation of vascular dysfunction was associated with the inhibition of the lipopolysaccharide/toll-like receptor 4 (LPS/TLR4) signaling, a protective effect that could be transferred via FMT. The antihypertensive and metabolic benefits of 2'-FL in mice were accompanied by gut-brain axis modulation. These findings suggest that 2'-FL represents a promising dietary strategy for preventing hypertension-associated complications.\n\nID: 41907517\nTitle: Obesity-associated gut microbiome influences diet-induced metabolic and cognitive outcomes in older adults.\nAbstract: Obesity in older adults is a known risk factor for Alzheimer's disease and related dementias, potentially driven by metabolic dysfunction, inflammation and gut dysbiosis. The gut-brain axis, influenced by diet and the gut microbiome, is increasingly recognized as a contributor to neurodegeneration. In this sub-analysis of a 10-week randomized dietary education intervention (NCT06121986), we examined how obesity modulates gut microbiome, metabolome, and cognitive responses in 31 adults aged 55-85, with or without mild cognitive impairment. Participants received education on either a Mediterranean Diet or a Modified Mediterranean-Ketogenic Diet. Analyses were stratified by baseline obesity (BMI\u2009\u226530 kg/m\u00b2). Individuals with obesity exhibited lower microbial alpha-diversity, higher Bacteroides, and lower Akkermansia and Christensenellaceae_R-7_group, along with poorer memory and executive function. Only in the obese group did fat loss correlate with improvements in episodic memory and cognitive flexibility. In contrast, increased fat mass was associated with improved memory in non-obese participants. Gains in skeletal muscle mass predicted cognitive improvement in adults aged\u2009\u226573. Changes in gut (acetate, propionate, lactate) and plasma (acetate, pyruvate, citric acid) metabolites were linked to cognitive and body composition outcomes. These exploratory findings highlight the gut-muscle-brain axis as a modifiable target to enhance cognitive health in aging populations.\n\nID: 41903401\nTitle: Short-chain fatty acids, neuroinflammation, and autism spectrum disorders: A mechanistic systematic review.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social and communication deficits, repetitive behaviors, and cognitive alterations. Increasing evidence indicates that immune dysregulation, particularly neuroinflammation, is central to its pathophysiology. The gut-brain axis and microbial metabolites, especially short-chain fatty acids (SCFAs: butyrate, acetate, propionate), have emerged as potential modulators of these processes. SCFAs are absorbed from the gut and may modulate brain function via transporter-dependent mechanisms at the BBB, although evidence in ASD contexts remains limited, thereby allowing them to influence both peripheral and central immune responses. This qualitative systematic review included studies published between 2015 and 2025 addressing at least one of three links: (1) ASD and neuroinflammation, (2) ASD and SCFAs, and (3) SCFAs and neuroinflammation. Twenty studies met inclusion criteria and were analyzed. Findings indicate that SCFAs exert distinct effects: butyrate consistently shows neuroprotective and anti-inflammatory actions, acetate displays context-dependent dual effects, and propionate is mainly associated with detrimental outcomes, including social and cognitive impairments and elevated inflammatory markers. Overall, SCFAs may influence ASD pathophysiology through modulation of neuroinflammatory mechanisms, with effects depending on the specific SCFA, dosage, and context. Nutritional strategies that modulate SCFA production, such as dietary fiber enrichment, prebiotics, and probiotics, may offer feasible, non-invasive therapeutic approaches. However, clinical evidence remains limited and heterogeneous, highlighting the need for well-designed trials to determine optimal interventions targeting SCFAs in ASD.\n\nID: 41839449\nTitle: Resveratrol Attenuates Neuroinflammation and Gut-Brain Axis Dysfunction Induced by Lead and Cadmium Co-Exposure by Modulating Gut Microbiota in Rats.\nAbstract: Resveratrol (RSV), a dietary polyphenol widely present in traditional medicinal plants and foods, exhibits antioxidant and anti-inflammatory properties that are relevant to ethnopharmacological strategies for protecting against environmental neurotoxicants. Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin. RSV attenuated cytokine release, normalized goblet cells, reversed dysbiosis by restoring Lactobacillaceae/Prevotellaceae, and increased acetate, propionate, and butyrate. It reinstated 5-HT and GABA while reducing SP and restoring VIP across serum, colon, and hippocampus. RSV attenuated Pb-Cd-associated neurotoxicity and was accompanied by improved intestinal and BBB-related readouts, partial normalization of gut microbiota features and SCFA levels, and preservation of synaptic and neurotransmitter-related markers, consistent with a link to gut-brain axis function. This study is among the first to test RSV in a Pb-Cd co-exposure model using a multi-dose regimen with integrated behavioral, barrier, microbial, and neurochemical endpoints.\n\nID: 41683284\nTitle: Varietal Differences in Kidney Beans Modulate Gut Microbiota and Inflammation During High-Fat Diet-Induced Obesity in Male Mice.\nAbstract: Background: Obesity-associated inflammation arises from adipose dysfunction and intestinal disturbances, including altered microbiota and short-chain fatty acid (SCFA) metabolism. Beans (Phaseolus vulgaris) are rich in non-digestible carbohydrates and polyphenols, but whether kidney bean varieties differing in seed coat colour exert distinct effects on inflammation in obesity remains unclear. Objective: To determine whether supplementation of an obesogenic high-fat (HF) diet with white or dark red kidney beans modulates gut microbiota, SCFAs, and intestinal, systemic, and neuroinflammatory outcomes. Methods: Male C57Bl/6N mice (n = 12/group) were fed a basal diet (BD; modified AIN-93G), an HF diet (60% kcal from fat), or an HF diet supplemented with 15% cooked white (HF + WK) or dark red kidney beans (HF + DK) for nine weeks. Outcomes included cecal microbiota composition, predicted KEGG pathways with taxon contributors mapped with BURRITO (a tool for linking predicted microbial functions to contributing taxa), and SCFA-related pathways; cecal and fecal SCFA concentrations; colon histomorphometry and expression of gut barrier junction and inflammatory genes; serum cytokines and adipose hormones; and hippocampal inflammatory and barrier genes. Results: Mice consuming bean-supplemented HF diets had higher microbial diversity, enrichment of SCFA-producing taxa (Prevotella, Lactobacillus, Muribaculaceae), and lower obesity-associated genera versus HF alone (Mucispirillum, rc4-4). Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase in both bean groups versus HF and BD, and butyrate kinase in HF + DK versus BD. Bean supplementation attenuated HF-induced reduction of goblet cells and systemic interleukin (IL)-10. The HF + DK group had lower colonic tumour necrosis factor (TNF)-\u03b1 and partially attenuated hippocampal IL-6. SCFAs were inversely associated with systemic and neuroinflammatory markers in HF + DK mice. Conclusions: Kidney bean supplementation mitigated HF diet-induced intestinal, systemic, and neuroinflammatory disturbances in male mice, with microbiota and SCFA modulation. Further, dark red beans exerted stronger anti-inflammatory effects, highlighting the role of seed coat colour in bean-mediated obesity outcomes.\n\nID: 41672225\nTitle: Bidirectional relationship between cancer and depression: From shared mechanisms to integrated therapeutic strategies.\nAbstract: Cancer and depression exhibit a clinically significant bidirectional association, as evidenced by the key findings: cancer patients are prone to depression, and depressed patients are prone to cancer. This may help explain why depression is commonly observed in cancer populations, where it is associated with poorer treatment adherence, diminished quality of life, and elevated mortality. Conversely, depression associated with an elevated cancer risk, potentially mediated by factors, such as neuroimmune dysregulation, chronic inflammation, and unhealthy lifestyles. Shared mechanisms include stress-induced \u03b2-adrenergic signaling, neuroinflammation, kynurenine pathway activation, and gut-brain-tumor axis disruptions involving bacterial metabolites like acetate. Common lifestyle factors such as smoking and sleep disruption, may further link both conditions through pathways like Wnt/\u03b2-catenin and JAK/STAT. Integrated treatment strategies combining anti-inflammatory medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or tumor necrosis factor-\u03b1 (TNF-\u03b1) inhibitors, psychotropic medications such as selective serotonin reuptake inhibitors (SSRIs), lifestyle modifications (e.g., exercise, Mediterranean diet) and psychotherapy (e.g., CBT) are promising for breaking the potential depression-cancer cycle and improving outcomes.\n\nID: 41607522\nTitle: Integrating microbial genomics and neurotranscriptomics to understand the impact of probiotic strains on neurological health.\nAbstract: The gut-brain axis is increasingly recognized as a key regulator of neurological health, with microbial metabolites influencing neurotransmission, synaptic plasticity, and neuroinflammation. Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium longum 1714 have been associated with neuroactive effects, yet the molecular mechanisms linking microbial genomic potential to host neuronal responses remain poorly defined. This study aimed to integrate microbial genomics, neurotranscriptomics, and in vitro validation to unravel the neuromodulatory effects of L. rhamnosus GG and B. longum 1714. Whole-genome functional annotation, metabolic pathway prediction, and biosynthetic gene cluster analysis were performed to identify neuroactive potential. Neuronal RNA-seq datasets (n = 3 biological replicates per condition) were analyzed using differential expression, WGCNA, and GSEA to capture transcriptomic responses. Multi-omics integration (CCA, DIABLO, SPIEC-EASI) linked microbial pathways with neuronal gene modules. In vitro assays using SH-SY5Y and iPSC-derived neurons validated predictions through measurements of cell viability, oxidative stress, neurotransmitter release (ELISA), qPCR of synaptic and inflammatory genes, and extracellular vesicle characterization including EV transcript profiling. Genomic analysis revealed that L. rhamnosus GG was enriched in \u03b3-aminobutyric acid (GABA) and SCFA pathways, while B. longum 1714 carried tryptophan-indole metabolism genes. Transcriptomic profiling demonstrated upregulation of synaptic genes (BDNF, SYN1), showed upregulation of synaptic genes (BDNF, SYN1), serotonergic transporters (SLC6A4, TPH2), and suppression of inflammatory mediators (IL-6, TNF-\u03b1). Integration analyses identified two major subnetworks: a \"neurotransmission module\" driven by L. rhamnosus GG and a \"serotonin-immune module\" driven by B. longum 1714. In vitro validation confirmed increased GABA (1.7-fold) and serotonin (1.5-fold) release, reduced ROS (-18 to -22%), and EV transcript enrichment for synaptic and anti-inflammatory markers. This multi-omics study demonstrates mechanistic evidence that probiotics exert complementary neuromodulatory effects: L. rhamnosus GG primarily enhances GABAergic and SCFA-mediated synaptic pathways, whereas B. longum 1714 regulates the tryptophan-serotonin-immune axis. Together, these findings support the therapeutic potential of precision probiotics for neurological health and establish a systems-level framework for probing host-microbe interactions.\n\nID: 41606419\nTitle: Functional Training Mitigates Reduced Circulating Indole-3-Lactate Levels in Persons With Relapsing-Remitting Multiple Sclerosis.\nAbstract: Indoles are tryptophan (Trp)-derived metabolites that are produced by the gut microbiota and may influence the gut-microbiota-brain axis in multiple sclerosis (MS). Indole-3-lactate (ILA) is reduced in persons with MS and improves MS clinical scores in animal models via its anti-inflammatory remyelinating properties. The ILA/indole-3-acetate (IAA) (ILA/AA) index is considered a neuroprotection index. Physical exercise and diet can modify gut microbiota and indole metabolism. This secondary analysis of a randomized control trial aimed to assess the effects of acute and chronic exercise on serum indoles in relapsing-remitting MS (RRMS). Thirty-one RRMS patients (\u2265\u200970% session attendance) completed a 10\u2009week multimodal functional training (60\u2009min, 3\u00d7/week) vs. a waitlist control group. Blood samples were collected at baseline and compared to a matched healthy control group, and after 10\u2009weeks for the assessment of chronic effects. Additionally, acute effects of a single bout of exercise were assessed with a blood sample before, during, and immediately after one interim training session. Serum indole concentrations were measured using LC-MS/MS. Baseline indole levels in RRMS patients differed from those of matched healthy controls, and reduced ILA levels were observed. The 10\u2009week intervention increased the ILA/IAA index, while a single exercise bout induced an increase in both ILA and ILA/IAA. Multimodal functional training over 10\u2009weeks led to an improved ILA/IAA index suggesting a neuroprotective shift in gut microbiota composition, and a single bout acutely increases the circulating level of ILA.

While probiotic therapies show promise, their mechanisms in mitigating neuropsychiatric comorbidities remain unclear. Here, we investigated the therapeutic potential of Akkermansia muciniphila-derived extracellular vesicles (AmEVs) in a murine model of dextran sulfate sodium (DSS)-induced colitis and associated cognitive deficits. AmEVs administration significantly alleviated colitis severity, as evidenced by improved weight retention, reduced disease activity index scores, and colon length restoration. Concurrently, AmEVs reversed colitis-driven cognitive impairments, restoring Y-maze and novel object recognition performance to baseline levels. Mechanistically, AmEVs repaired intestinal and blood\u2012brain barrier integrity by upregulating tight junction proteins, suppressed neuroinflammation via reduced hippocampal pro-inflammatory cytokines, and inhibited microglial/astrocyte activation. Gut microbiota analysis revealed that AmEVs-mediated enrichment of beneficial Bifidobacterium and suppression of pathogenic Bacteroides and Mucispirillum, alongside restored short-chain fatty acid (SCFA) production. Crucially, AmEVs bidirectionally regulated tryptophan metabolism, reducing colonic serotonin (5-HT) overproduction while restoring hippocampal 5-HT levels and 5-HT1A receptor expression. This was accompanied by enhanced synaptic plasticity and BDNF upregulation in the hippocampus. Proteomic and biodistribution studies confirmed AmEVs' delivery of metabolic regulators to hippocampal neurons, including the key protein Amuc_1100,directly enhancing 5-HT production in vitro. Our findings establish AmEVs as a multifaceted therapeutic agent that concurrently resolves gut inflammation and cognitive deficits via gut-brain axis modulation, offering novel strategies for IBD-related neuropsychiatric comorbidities. Further research is warranted to validate critical vesicular components and optimize clinical translation.\n\nID: 41459064\nTitle: Potential effects of cinnamon on cancer prevention and progression.\nAbstract: Cinnamon has been used medicinally for centuries, but recently in vitro research has suggested it may have a role in cancer prevention and potentially treatment. The search for alternative and subjunctive therapies is essential due to the public demand and the increasing cost of healthcare. Here we review the biologically active components of cinnamon and discuss the methods of potential cinnamon activity against cancer, including: transcription factor regulation and kinase activity. Nuclear Factor kappa B (NF\u03baB) is a stress sensitive transcription factor that regulates transcription of genes involved in tumor progression and is inhibited by cinnamon components. Another way that cinnamon inhibits tumor growth is by suppression of transcription factor activator protein 1 (AP1) which interacts with genes responsible for apoptosis, metastasis and inflammation. Hypoxia-inducible transcription factor 1 (HIF1) and vascular endothelial growth factor (VEGF) are involved in angiogenesis, especially in the tumor microenvironment. The HIF1-VEGF pathway is a target of cinnamaldehyde, a compound found in cinnamon. Nuclear factor erythroid related factor 2 (Nrf2) is also examined and has been indicated to affect cancer progression and potentially provide preventative measures; various cinnamon derivatives target Nrf2. A cinnamaldehyde derivative has been implicated in a reduction of the mitogen-activated protein kinases (MAPKs), which are a group of kinases that regulate proliferation. Additionally, cinnamon components have been tied to cancer prevention by positively affecting the gut microbiome and inhibiting inflammation. The review concludes with a discussion of the future research needed, including the need for clinical studies and potential risk associated with cinnamon intake.\n\nID: 41421404\nTitle: Neuroprotective effects of Prosopis cineraria L. ameliorate Alzheimer's disease manifestations.\nAbstract: Prosopis cineraria is traditionally used to enhance cognitive function and manage mental disorders. Its stem bark is valued in ethnomedicine, but its potential anti-Alzheimer's disease (AD) effects are scientifically unexplored. This research has examined the neuroprotective effects of the ethyl acetate fraction of P. cineraria bark (Pc-EA) against AlCl3-induced AD pathology, focusing on behavioral, biochemical, histological, and molecular outcomes. Diseased rats were treated with Pc-EA (30, 100, and 300\u00a0mg/kg) for 42 days. Cognitive and affective functions were evaluated with behavioral tests on days 29-42. Biochemical assays measured oxidative stress and cholinesterase activity, while RT-PCR quantified neuroinflammatory markers. Histopathological examination was performed to evaluate the integrity of hippocampal regions. Bioactive compounds were identified by phytochemical profiling (HPLC, GC-MS), and molecular docking was performed to assess binding interactions with acetylcholinesterase. AlCl3 exposure impaired memory, augmented anxiety and depression-like behavior, elevated oxidative stress, AChE activity, and induced hippocampal neurodegeneration with upregulated BACE-1, Tau, Caspase-3, and NF-\u03baB alongside downregulated BDNF. These changes were reversed by Pc-EA (100\u00a0mg/kg), which enhanced cognitive function, restored antioxidant defense, inhibited AChE and neuroinflammatory markers, and maintained hippocampal architecture. Bioactive phytoconstituents (chlorogenic acid, kaempferol, quercetin), which exert anti-amyloidogenic, antioxidant, anti-inflammatory, and acetylcholinesterase inhibitory effects, were identified by HPLC and GC-MS, and their potential roles were corroborated via in silico validation. Pc-EA demonstrated multi-targeted neuroprotection in AlCl3-induced AD, which is consistent with ethnomedicinal claims. These findings indicate P. cineraria as a potential modulator of AD through antioxidant, anti-inflammatory, anti-amyloidogenic, and neurotrophic mechanisms.\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: 41403319\nTitle: Dietary kaempferol attenuates aging-related cognitive decline through gut microbiota modulation and intestinal barrier strengthening with suppression of neuroinflammation in mice.\nAbstract: Kaempferol, a natural dietary flavonoid, has shown neuroprotective potential. However, its mechanisms of protection against age-related cognitive decline, especially those mediated via the gut-brain axis, are not fully understood. This study investigated the role of kaempferol in alleviating D-galactose-induced brain aging and elucidated its functional mechanisms related to gut microbiota composition, microbial metabolite production, and intestinal barrier integrity. An aging mouse model was induced by D-galactose and subsequently treated with kaempferol. Results revealed that kaempferol significantly ameliorated anxiety-like behaviors and spatial working memory deficits in D-galactose-treated mice. In the hippocampus, it reduced neuronal loss, upregulated synaptic plasticity-related genes (Bdnf and Snap25), and suppressed neuroinflammation through inhibition of microglial activation and the TLR4/Myd88 signaling pathway. Importantly, kaempferol restored intestinal barrier integrity, as indicated by increased expression of colonic MUC2 and tight junction proteins (Zo-1 and Occludin). It also markedly reshaped gut microbiota composition by enriching beneficial genera such as Faecalibaculum and Akkermansia, which correlated with elevated fecal propionate and butyrate levels, and a reduction in serum LPS. Our findings demonstrate that kaempferol mitigates D-galactose-induced cognitive impairment by modulating gut microbiota, increasing beneficial SCFA production, enhancing gut barrier function, and subsequently inhibiting systemic and neuroinflammation. This study provides mechanistic support for kaempferol as a dietary intervention strategy to promote brain health via the gut-brain axis.\n\nID: 41366428\nTitle: Microbial production of short-chain fatty acids attenuates long-term neurologic impairment after traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) triggers persistent gut microbiome dysbiosis characterized by depletion of short-chain fatty acid (SCFA)-producing bacteria. However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease.\n\nID: 41360561\nTitle: L-theanine alleviates reserpine-induced depression in rats via modulation of the gut-brain axis.\nAbstract: L-theanine, a natural amino acid in tea, exhibits potential neuroprotective effects. However, its impact on depression via the microbiota-gut-brain axis remains unclear. Here, L-theanine alleviated reserpine-induced depression-like behaviors in rats, improving anhedonia, despair, and cognitive deficits, while reducing serum IL-1\u03b2, IL-6, and TNF-\u03b1, restoring hippocampal BDNF, and mitigating neuronal damage. Multi-tissue non-targeted metabolomics (serum, brain, colon, feces) revealed that L-theanine reversed phospholipid and bile acid disturbances and restored key neuroprotective metabolites. Targeted metabolomics validated the non-targeted findings by confirming that L-theanine alleviated bile acid dysregulation and restored SCFA profiles. Additionally, L-theanine modulated gut microbiota composition, increasing beneficial genera such as Alloprevotella and Prevotellaceae_UCG-001, while reducing potentially harmful taxa. Correlation analyses indicated that these microbiota changes were linked to bile acid and SCFA profiles, suggesting gut-brain axis involvement. Overall, L-theanine exerts antidepressant effects by modulating neuroinflammation, neuroplasticity, and metabolism, highlighting its potential as a functional food for depression.\n\nID: 41317578\nTitle: Bilobalide isolated from Ginkgo leaf tea alleviates Parkinson's disease via suppressing neuroinflammation and remodeling gut microbiota.\nAbstract: Parkinson's disease (PD) is a prevalent neurodegenerative disorder with limited effective treatments. Ginkgo leaf tea (GLT), derived from the dried leaves of Ginkgo biloba, has long been consumed for its cardiovascular and neurological health benefits. However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases.\n\nID: 41294874\nTitle: Valeric Acid: A Gut-Derived Metabolite as a Potential Epigenetic Modulator of Neuroinflammation in the Gut-Brain Axis.\nAbstract: The gut-brain axis (GBA) is a critical area of research for understanding the pathogenesis of neuroinflammatory and neurodegenerative diseases. Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA.\n\nID: 41177025\nTitle: Bisphenol-A at an environmentally plausible dose caused gut microbiota-led impaired cognitive performances in adult mice.\nAbstract: Omnipresent Bisphenol-A (BPA) exposure is linked to neurobehavioral deficits and gut dysbiosis. However, studies assessed its impact on cognitive performance at environmentally unrealistic doses. Nevertheless, the exact mechanism underlying the neurobehavioral phenotype, linking the role of gut microbiota is poorly understood. Here, we evaluated the effects of environmentally plausible dose of BPA-exposure on cognitive task performances with the functional analysis of gut metagenome to elucidate the role of microflora-gut-brain axis in behavioural regulation. Swiss albino mice were exposed to BPA for 5 weeks assessed for working and spatial navigation task performances. qRT-PCR based gene expression, histological investigation, gut permeability, molecular and biochemical markers of neuro-inflammation, leaky gut, oxido-nitrosative stress and 16\u202fs rRNA gene based metagenomics with functional analysis were performed. BPA exposure altered the cognitive task performances (mean difference for transfer latency in elevated plus maze 20.84\u202f\u00b1\u202f5.64\u202fsec in and -13.12\u202f\u00b1\u202f3.53 in Morris' water maze), changed serotonin levels (-70.95\u202f\u00b1\u202f21.43) and acetylcholinesterase activity (0.0032\u202f\u00b1\u202f0.0008), enhanced ileal permeability (12.36\u202f\u00b1\u202f3.56) and systemic and tissue level inflammation (increased brain LPS, TNF-a, IL-1b, IL-6 and circulating TNF-a and IL-1b), coupled with reduced SCFAs levels (acetate; 32.48\u202f\u00b1\u202f8.48, and butyrate; 28.16\u202f\u00b1\u202f9.86). Faecal microbial transplant cohort replicated similar behavioural, biochemical and molecular patterns, suggesting the role of gut-microbiota in the phenotype determination. Functional pathways prediction suggested altered serotonin, dopamine, SCFAs metabolism and LPS biosynthesis. BPA at a much lower but environmentally relevant dose altered the cognitive performances, which has potential linkage to gut-microbiota mediated pathways.\n\nID: 41160277\nTitle: Comprehensive chemical analysis of polyphenols in the ethyl acetate extract from the roots of Ephedra sinica Stapf and evaluation of its therapeutic effects on SU5416/hypoxia-induced pulmonary arterial hypertension rats.\nAbstract: Pulmonary hypertension (PH) is a deadly disease with limited treatment options and poor long-term survival, necessitating the discovery of novel therapeutics. Our previous study has revealed that dimeric proanthocyanidins (PACs) mainly existed in the ethyl acetate extract from the roots of Ephedra sinica Stapf (ERE), however, its therapeutic effects on SU5416/hypoxia-induced pulmonary hypertension (PH) rats remain elusive. In this study, column chromatography combined with UPLC-LTQ-Orbitrap-HRMS analysis was performed to comprehensively characterize polyphenols in ERE. The therapeutic effects of ERE were investigated using the SU5416/hypoxia rat model, in which the rats were injected with SU5416 (20 mg/kg), followed by a three-week hypoxia exposure (10% O2). Hemodynamic indicators determined by right heart catheterization, pulmonary arterial morphological changes assessed by histopathological analysis, cardiac function and pulmonary hemodynamics using echocardiography, as well as oxidative stress markers measured by corresponding kits were used to test the therapeutic effects of ERE. Moreover, 16S rRNA sequencing combined with untargeted metabolomics was employed to capture changes in gut microbiota and serum metabolites after ERE treatment. Comprehensive chemical analysis of polyphenols in ERE revealed various levels of proanthocyanidin monomers, dimers and trimers, especially A-type dimers. In vivo experiments showed that ERE decreased pulmonary arterial pressure, right ventricular hypertrophy, right ventricular free wall (RVFW) thickness and oxidative stress levels, increased pulmonary acceleration time (PAT) and alleviated pulmonary vascular remodeling in rats exposed to SU5416/hypoxia treatment. Meanwhile, ERE improved gut microbial dysbiosis and the disturbed glycerophospholipid metabolism. Collectively, this study presents the first report on the efficacy of A-type PACs from Ephedra sinica for the treatment of PH through regulating gut microbiota and host metabolism.\n\nID: 41123675\nTitle: Short-Chain Fatty Acids as a Therapeutic Strategy in Parkinson's Disease: Implications for Neurodegeneration.\nAbstract: Neurodegeneration involves the progressive deterioration of neuronal structure and function, leading to deficits in cognition, motor skills, and other neurological processes. Parkinson's disease (PD) is notably prevalent among neurodegenerative disorders, characterized by dopaminergic neurodegeneration, protein misfolding, and an inflammatory brain environment. Despite advancements in understanding its pathophysiology, PD and other neurodegenerative conditions still lack effective disease-modifying therapies. This shortfall highlights the need for novel, multifactorial approaches to treatment. Recent research has spotlighted the gut-brain axis as a significant player in neurological health, particularly through the activity of gut-derived short-chain fatty acids (SCFAs). These microbial metabolites, primarily acetate, propionate, and butyrate, are produced via the fermentation of dietary fibers and are vital for maintaining intestinal and neural homeostasis. SCFAs exert anti-inflammatory effects, preserve blood-brain barrier integrity, and modulate neurotransmitter systems. Among them, butyrate shows notable neuroprotective capabilities, including histone deacetylase inhibition and mitochondrial enhancement. Disruption in SCFA production has been associated with PD progression, further underscoring their relevance. This review explores the mechanistic roles of SCFAs in modulating neurodegeneration, with an emphasis on PD. SCFA-based strategies offer a promising adjunctive route to restoring microbial balance, mitigating neuroinflammation, and safeguarding neurological function in neurodegenerative disorders.\n\nID: 41080555\nTitle: A high-calorie diet exacerbates lipopolysaccharide-induced pneumonia by promoting acetate-mediated macrophage polarization via the HDAC9/10-HIF-1\u03b1-glycolysis axis.\nAbstract: Lung macrophage polarization imbalance is an important cause of aggravated pulmonary inflammation. The gut microbiota metabolites short-chain fatty acids (SCFAs) are an important regulator of macrophage polarization. A high-calorie diet has been shown to aggravate pneumonia and delay recovery, especially in children. However, the underlying mechanisms remain unclear. Our previous studies showed that a high-calorie diet can disrupt the gut microbiota structure and SCFA metabolism to aggravate LPS-induced lung inflammatory damage in juvenile rats. In this study, we investigated whether pneumonia aggravated owing to a high-calorie diet is associated with SCFA-driven macrophage phenotype changes in distal lung tissues and related mechanisms. Our data revealed that a high-calorie diet significantly aggravated pulmonary inflammatory injury in juvenile mice with LPS-induced pneumonia and also increased lung tissue M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization imbalance. We found that a high-calorie diet decreased SCFA levels in mouse stool, serum, and lung tissues, which was most pronounced for acetate. Furthermore, we found that acetate reduction mediated by a high-calorie diet exacerbated M1-like (CD206\u207bCD86\u207a)/M2-like (CD206\u207aCD86\u207b) macrophage polarization imbalance in the lung tissue of pneumonia model mice and was associated with inhibiting histone deacetylase (HDAC), rather than G-protein-coupled receptor 43 (GPR43) signaling. More critically, we found that acetate supplementation had the most significant impact on HDAC9 and HDAC10 in the lung macrophages of pneumonia model mice fed a high-calorie diet. Furthermore, overexpression of Hdac9 and Hdac10 significantly attenuated the improvement effects of acetate on lung tissue M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization in pneumonia model mice fed a high-calorie diet, and this mechanism was associated with the HIF-1\u03b1-glycolysis axis. Taken together, we demonstrated that a high-calorie diet could cause acetate levels to decrease in mice with LPS-induced pneumonia. This decrease in acetate was associated with a diminished inhibitory effect on HDAC9/10, potentially contributing to upregulation of HIF-1\u03b1 expression and increased glycolysis. These changes may be linked to an imbalance in M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization and aggravate lung tissue inflammatory injury. Our findings show that acetate supplementation may be a potential treatment strategy to prevent and treat pneumonia and other infectious diseases.\n\nID: 41045636\nTitle: Comparative neuroprotective efficacy of N-acetylcysteine and naringin in lead-induced neurotoxicity: Restoration of BDNF, neurotransmitters, and cognitive function.\nAbstract: Exposure to lead acetate is reported to induce neurotoxicity associated with cognitive dysfunction, neurotransmitter dysfunction, oxidative stress, neuroinflammation, and neuronal damage in the hippocampus. Flavonoids and other natural compounds possessing antioxidant and neuroprotective properties can be of therapeutic interest. In the current study, naringin's protective property as a flavonoid was compared with that of N-acetylcysteine (NAC) against lead-induced neurotoxicity in rats. Adult rats were randomly distributed into control, lead acetate-treated, lead+NAC-treated, lead+low-dose naringin, and lead+high-dose naringin groups, each group containing 6 animals. The Novel Object Recognition (NOR) test was used for the evaluation of cognitive function. Biochemical analysis of hippocampal glutamate, acetylcholine, Brain-Derived Neurotrophic Factor (BDNF), Nuclear factor erythroid 2-related factor 2 (Nrf2), pro-inflammatory markers (IL-6, GFAP), and serum lead levels was done. Histopathological analysis of hippocampal sections by crystal violet staining was done. Exposure to lead acetate-induced severe neurotoxicity in the guise of compromised recognition memory, reduced glutamate and acetylcholine content, reduced BDNF and Nrf2 expression, increased IL-6 and GFAP content, and severe hippocampal neuronal damage. NAC treatment effectively reversed cognitive function, neurotransmitter content, neurotrophic factors, and diminished neuroinflammation. Dose-dependent neuroprotection was afforded by naringin, where the high-dose group had better recovery in all the parameters than the low-dose group. Interestingly, high-dose naringin was similar to or even larger than that of NAC's neuroprotection, normalization of hippocampal histoarchitecture, enhancement of antioxidant defense, and decrease in pro-inflammatory markers and serum lead levels. Lead acetate causes profound neurotoxicity on cognition, neurotransmission, oxidative stress, and inflammation. Naringin, especially at high doses, exhibits highly potent neuroprotective effects, such as NAC, preventing lead-induced cognitive dysfunction and hippocampal pathology by displaying antioxidant, anti-inflammatory, and neurotrophic effects. The results propose naringin as a potential natural drug candidate for preventing and/or treating lead-induced neurotoxicity.\n\nID: 40993201\nTitle: Fibre supplementation alters the gastrointestinal microbiome, the microbial metabolites and indicators of neurodegeneration in a mouse model of Alzheimer\u00b4s disease.\nAbstract: Alzheimer\u00b4s disease is a neurodegenerative disease with high global prevalence and no cure available. It is known that the microbiota-gut-brain-axis plays a role in the pathogenesis, but the pathways are not fully understood yet. To elucidate the role of dietary fibre supplementation on this axis in a 5xFAD mouse model of Alzheimer\u00b4s disease, a feeding trial with an inulin supplement was conducted. At the start (Basis, n\u2009=\u200911) and after 7 weeks with (AD\u2009+\u2009F; n\u2009=\u200915) and without (AD; n\u2009=\u200915) supplementation, the mice were sacrificed and the following samples were taken: ingesta for 16\u00a0S rRNA sequencing and short-chain fatty acid (SCFA) analysis, and brain tissue for amyloid-beta staining and proteome analysis. The microbiota patterns in stomach, small intestine, caecum and colon differed between AD and AD\u2009+\u2009F. SCFA concentrations were significantly higher in group AD\u2009+\u2009F as compared to AD and Basis. In the AD mice, plaque load was significantly increased as compared to Basis, while a reduction in AD\u2009+\u2009F as compared to AD was observed. The brain proteome also differed between AD\u2009+\u2009F and AD, indicating a beneficial effect of the inulin supplementation, possibly mediated in part by microbial acetate. Since prebiotic substances like inulin are also part of human diets, this should be investigated further in the translational context.\n\nID: 40961414\nTitle: Short-Chain Fatty Acid Supplementation After Traumatic Brain Injury Attenuates Neurologic Injury Via the Gut-Brain-Microglia Axis.\nAbstract: Traumatic brain injury (TBI) is an underrecognized public health threat. There are limited therapeutic options for TBI, and supportive care remains the mainstay of treatment. Our previously published data demonstrate that post-TBI fecal microbiome transplantation (FMT) can reverse TBI-induced depletion of commensal bacteria, preserve white matter connectivity and neurocognition, and decrease cortical volume loss in mice after TBI. We hypothesized that post-TBI supplementation with short-chain fatty acids (SCFAs), metabolites of commensal gut bacteria, would attenuate neurologic injury after TBI in mice. 14-week-old male C57BL/6 mice ( n = 52) underwent TBI via a controlled cortical impact versus sham injury. Post-TBI, each group was treated with the SCFAs acetate, butyrate, and propionate versus a molar-equivalent sodium chloride vehicle via free access to drinking water for 4 weeks post-TBI. The stool was collected 3 days pre- and 60 days post-TBI to assess the gut microbial community structure via 16s ribosomal RNA gene amplicon sequencing. Neurocognitive testing was performed with open-field and zero-maze testing. Ventricular volume and white matter connectivity were measured with 3D, contrast-enhanced magnetic resonance imaging. Lastly, the transcriptional response of microglia was assessed with single-cell RNA sequencing (scRNAseq). SCFA supplementation decreased TBI-induced microbial loss, attenuated ventricular volume loss, preserved white matter connectivity, and altered the transcriptional profile of microglia after TBI. Post-TBI SCFA supplementation preserved the abundance of the butyrate-producing taxa Firmicutes, Clostridia, Ruminoccacaceae , and Peptoccacaceae ( P\u2009=\u2009 0.01). SCFA also reduced the TBI-induced increase in Clostridiales and Bacteroidales compared with the salt vehicle group ( P\u2009=\u2009 0.05). We also observed the preservation of non-TBI murine anxiety-like behavior in SCFA-treated TBI mice compared with vehicle-treated TBI mice in the zero-maze (152.3 \u2009 \u00b1 \u2009 101.8\u2009cm vs. 147.5 \u2009 \u00b1 \u2009 60.0\u2009cm, P\u2009=\u2009 0.006). These results were recapitulated with open-field testing (11.7 \u2009 \u00b1 \u2009 3%-time in the center in SCFA-treated TBI mice vs. 15.0 \u2009 \u00b1 \u2009 6%-time in the center of the field in vehicle-treated mice; P\u2009=\u2009 0.002). Lastly, we observed upregulation of transcripts for the neuroprotective heat-shock family of proteins and downregulation of neurodegeneration-associated transcripts, indicating an overall neuroprotective phenotype in microglia after SCFA supplementation post-TBI. We hypothesized that SCFA supplementation would attenuate neurologic injury after TBI in mice. SCFA supplementation attenuated neurocognitive deficits, reduced cortical volume loss, preserved white matter connectivity, and decreased neuroinflammation. These benefits may result from the direct replacement of SCFAs. However, there may also be secondary mechanisms related to commensal refeeding of butyrate-producing bacteria within the gut microbial community, a neuroprotective heat-shock response, and a decrease in the expression of genes associated with neurodegeneration. The current study highlights the role of SCFAs in microbiome homeostasis and the potential of dietary intervention as a novel therapy in TBI.\n\nID: 40838741\nTitle: Serotonergic and immunomodulatory properties of the psychobiotic candidate Bacteroides finegoldii UO.H1052 and its extracellular vesicles.\nAbstract: Bacteroides finegoldii UO.H1052, a human gut commensal, was evaluated for its potential psychobiotic and immunomodulatory properties. Whole-genome analysis confirmed the absence of virulence factors, plasmids, and antibiotic-resistance genes. Metabolomic profiling of cell-free supernatants (CFSs) and extracellular vesicle (EV) postbiotics revealed a high- and medium-dependent production of neuroactive metabolites, including \u03b3-aminobutyric acid, tryptophan, tyrosine, and tyramine, as well as physiologically relevant levels of short-chain fatty acids, such as acetate, propionate, and butyrate. Functionally, CFS enhanced epithelial barrier integrity by increasing transepithelial electrical resistance and mitigating LPS-induced disruption in Caco2/HT29 monolayers without cytotoxic effects. Both CFS and EVs exhibited immunomodulatory properties, characterized by elevated Il-10/Tnf-\u03b1 ratios under basal conditions and significant suppression of Tnf-\u03b1 expression in LPS-stimulated RAW 264.7 macrophages. Notably, CFS and EVs increased tryptophan hydroxylase 1 (Tph1) gene expression in enterochromaffin RIN14B cells by 6.6- and 3.2-fold, respectively, suggesting enhanced serotonergic activity. These findings highlight B. finegoldii UO.H1052 as a promising next-generation psychobiotic candidate with neuroactive, barrier-protective, and immunoregulatory properties, supporting its potential for gut-brain axis modulation. Emerging evidence supports the critical role of the gut microbiota in modulating host neurophysiology and immune function via the gut-brain axis. Here, we present a comprehensive characterization of Bacteroides finegoldii UO.H1052, a human gut commensal that exhibits promising psychobiotic attributes, including the production of neuroactive compounds and extracellular vesicles (EVs) with immunoregulatory and serotonin-inducing properties. The strain exhibits a favorable safety profile, with no detected virulence factors or transmissible antibiotic resistance. Importantly, cell-free supernatants and EVs enhanced epithelial barrier integrity, modulated pro- and anti-inflammatory cytokine responses, and significantly upregulated the expression of Tph1, a key enzyme in serotonin biosynthesis. These findings underscore the potential of B. finegoldii UO.H1052 as a next-generation psychobiotic candidate and highlight EVs as effective postbiotic mediators of host-microbe communication. This study advances the understanding of Bacteroides-derived psychobiotics and provides a foundation for their development in modulating gut-brain and immune pathways relevant to neuroinflammatory and gastrointestinal disorders.\n\nID: 42489766\nTitle: Pentoxifylline targets TLR4/MyD88/NF-\u03baB signaling to ameliorate neuroinflammation and metabolic dysfunction in a rat model of chronic hypoperfusion-induced vascular cognitive impairment.\nAbstract: Vascular cognitive impairment (VCI) driven by chronic cerebral hypoperfusion lacks disease-modifying therapy. We tested whether pentoxifylline (PTX), a methylxanthine phosphodiesterase inhibitor with dual hemorheological and anti-inflammatory properties, attenuates VCI-like cognitive and inflammatory abnormalities in a rat model. Three-month-old male Sprague-Dawley rats underwent bilateral common carotid artery occlusion (BCCAO) or sham surgery. PTX (60\u00a0mg\u00a0kg\u207b1\u00a0day\u207b1, gavage) or vehicle was administered for 28\u00a0days starting 24\u00a0h post-operation. Spatial cognition was assessed with the Morris water maze; neuronal injury, microglial activation, and glucose metabolism were evaluated by histology, immunofluorescence, 1\u2078F-FDG PET/CT, and western blotting. Systemic and hippocampal cytokines were quantified by multiplex immunoassay; TLR4/MyD88/NF-\u03baB signaling was profiled by RNA-seq and western blotting. BCCAO induced progressive cognitive deficits without sustained weight loss, paralleled by CA1 neuronal damage, microglial proliferation, and marked elevations of IL-1\u03b2, IL-2, IL-17, and TNF-\u03b1 in plasma and hippocampus. PTX shortened escape latency, restored probe-trial platform crossings, preserved neuronal morphology, suppressed microglial Iba-1\u207a/Ki67\u207a expansion, and reduced all four cytokines. Mechanistically, PTX down-regulated TLR4, MyD88, and NF-\u03baB p65 mRNA and protein, reduced nuclear translocation of NF-\u03baB p65, and partially reversed frontal and hippocampal glucose hypometabolism. Peripheral IL-1\u03b2 and IL-17 levels correlated positively with cognitive impairment. Pentoxifylline concurrently mitigates hypoperfusion-associated neuroinflammation, neuronal injury, and glucose hypometabolism via inhibition of the TLR4/MyD88/NF-\u03baB axis, supporting PTX as a readily translatable candidate for early VCI intervention.\n\nID: 42488724\nTitle: BDNF-amyloid-\u03b2 Axis in Alzheimer's disease: molecular mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD), the most common cause of dementia in older adults, is characterized by progressive cognitive decline, synaptic dysfunction, and neuronal loss. Among the multifactorial mechanisms implicated in AD, reciprocal interactions between brain-derived neurotrophic factor (BDNF) and amyloid-\u03b2 (A\u03b2) have attracted increasing attention as a convergent axis linking amyloid pathology to impaired neurotrophic support. BDNF promotes neuronal resilience, synaptic plasticity, and cognitive function primarily through the activation of its high-affinity receptor, tropomyosin receptor kinase B (TrkB), and downstream signaling pathways, including PI3K-Akt and MAPK/ERK. Human postmortem and biomarker studies mainly support associations between reduced BDNF signaling, synaptic dysfunction, and AD-related pathology. In contrast, cell-based and animal studies provide mechanistic evidence that BDNF/TrkB signaling may influence amyloid precursor protein (APP) processing and neuronal resistance to A\u03b2-induced stress. Conversely, mechanistic studies indicate that A\u03b2 accumulation can suppress CREB-dependent BDNF expression, disturb BDNF transport, and impair TrkB receptor function. Thus, the BDNF-A\u03b2 relationship is better interpreted as a stage- and context-dependent pathogenic coupling rather than a simple causal loop. This review synthesizes evidence from human studies, animal models, and cellular systems to clarify how BDNF-A\u03b2 dysregulation contributes to AD progression and to discuss the translational potential of BDNF-oriented interventions.\n\nID: 42486321\nTitle: The Pan-Salt-inducible Kinase Inhibitor YKL-06-061 Exerts Antidepressant-like Effects via Hippocampal CRTC1-CREB-BDNF Pathway Activation in Chronic Stress Models.\nAbstract: Current monoaminergic antidepressants demonstrate limited efficacy and delayed onset, necessitating novel treatment strategies. We previously identified hippocampal salt-inducible kinase 2 (SIK2) as an important regulator of depression pathogenesis through modulation of the cAMP response element-binding protein (CREB)-regulated transcription coactivator 1 (CRTC1)-CREB-brain derived neurotrophic factor (BDNF) pathway. The current study investigated the antidepressant-like efficacy of YKL-06-061, a newly developed potent pan-SIK inhibitor, in male C57BL/6J mice. We established two well-validated depression models, chronic social defeat stress and chronic unpredictable mild stress, to examine the efficacy of daily intraperitoneal YKL-06-061 injection against behavioral despair as measured by forced swim and tail suspension tests, anhedonia as measured by sucrose preference, and social withdrawal as measured by the social interaction test. Western blotting, immunofluorescence, and co-immunoprecipitation were then conducted to evaluate the changes in hippocampal SIK2-CRTC1 signaling, BDNF-TrkB signaling, and adult neurogenesis among all groups. To further determine the antidepressant mechanism of YKL-06-061, model mice were re-examined following adeno-associated virus (AAV)-mediated overexpression of hippocampal SIK2 or knockdown of hippocampal CRTC1/CREB/BDNF. YKL-06-061 administration suppressed depression-like behaviors in both models, normalized chronic stress-induced alteration in hippocampal SIK2-CRTC1 signaling, and rescued chronic stress-induced impairments in hippocampal BDNF signaling and adult neurogenesis. Both genetic overexpression of hippocampal SIK2 and knockdown of hippocampal CRTC1/CREB/BDNF expression attenuated the antidepressant-like actions of YKL-06-061 in mice. Our findings further establish hippocampal SIK2-CRTC1-CREB-BDNF signaling as an antidepressant target and support YKL-06-061 as a potential antidepressant candidate.\n\nID: 42485732\nTitle: Calcium signaling in microglial immune functions: current understanding and implications for disease.\nAbstract: Microglia are the resident innate immune cells of the brain that play essential roles in immune surveillance, phagocytosis, and neuroinflammatory responses. A central regulator of these diverse functions is intracellular Ca2+ signaling, which connects extracellular cues to transcriptional and metabolic programs that shape microglial activation states. Recent advances have expanded understanding of the 'Ca2+ toolkit' in microglia, which includes P2X and P2Y receptors, Orai Ca2+ channels, transient receptor potential channels, inositol triphosphate receptors, and organellar Ca2+ handling systems. These pathways generate dynamic and spatially localized Ca2+ signals that regulate numerous effector functions, including process motility, cytokine production, phagocytosis, metabolism, and communication with other brain cells. Emerging evidence further identifies dysregulated Ca2+ signaling as a key driver of chronic neuroinflammation in brain disorders. Here, we review the major components of the microglial Ca2+ signaling toolkit, discuss their molecular mechanisms and physiological functions, and highlight contributions to neuroinflammatory diseases.\n\nID: 42482393\nTitle: Quantifying Heteromer Partitioning Reveals Inflammation-Dependent Redistribution of Microglial Adenosine A2A and Cannabinoid CB2 Receptors.\nAbstract: G protein-coupled receptor (GPCR) heteromerization represents a key organizational mechanism in cell signaling, but it remains difficult to determine, in native cells, how receptor-associated signals are distributed between non-interacting and heteromer-associated states. Here, we address this limitation by combining proximity ligation assay (PLA) with the newly applied MolBoolean methodology, enabling in\u00a0situ quantification of the partitioning of adenosine A2A and cannabinoid CB2 receptor-associated signals between non-interacting fractions and A2A-CB2 heteromeric complexes in primary microglia. We show that resting microglia contain detectable A2A-CB2 heteromers together with a substantial non-interacting A2A-associated signal fraction. Selective activation of either receptor promotes redistribution of the detectable receptor-associated signal toward the heteromer-associated fraction. Ligand-induced redistribution also occurred in HEK-293T cells expressing the two receptors. In contrast, pro-inflammatory activation of primary microglia with LPS/IFN-\u03b3 markedly changes the basal organization of the receptor system, increasing the proportion of MolBoolean-detectable signal associated with A2A-CB2 complexes, with approximately 70% of the detectable receptor-associated signal corresponding to heteromeric complexes. In this inflammatory context, further agonist-induced repartitioning is strongly limited compared with that observed in resting microglia. These findings identify inflammation-dependent receptor partitioning as a quantitatively measurable feature of microglial A2A and CB2 receptor organization and provide a framework for interpreting how receptor context may influence future studies of A2A-CB2 pharmacology under neuroinflammatory conditions.\n\nID: 42482223\nTitle: Targeting progressive multiple sclerosis: Toward mechanism-informed precision medicine.\nAbstract: Multiple sclerosis has undergone a therapeutic revolution over the past three decades. Randomized clinical trials and real-world data demonstrate that modern disease-modifying therapies substantially reduce relapse rates and acute inflammatory activity detected by magnetic resonance imaging (MRI). However, disability accumulation increasingly occurs independent of relapse activity, highlighting progression biology as the principal unmet need. Converging epidemiological and molecular evidence supports a pivotal role for Epstein-Barr virus (EBV) infection in disease initiation, whereas later stages appear dominated by brain-intrinsic mechanisms, including compartmentalized inflammation, microglial activation, failure of remyelination and accelerated biological ageing. Population-based cohorts demonstrate that early high-efficacy therapy improves long-term outcomes, yet the risk of progression rises markedly after midlife despite effective relapse suppression. Emerging biomarkers, such as serum neurofilament light chain, glial fibrillary acidic protein, paramagnetic rim lesions and advanced quantitative MRI metrics, now enable more granular monitoring of progressive pathology. Integration of imaging, fluid biomarkers, genetics and machine learning offers opportunities for individualized benefit-risk stratification. Brain-penetrant Bruton's tyrosine kinase inhibitors, CD40 ligand-targeting biologics, refined B-cell-depleting strategies and emerging chimeric antigen receptor T-cell therapies represent promising approaches to target different aspects of compartmentalized inflammation and smoldering disease biology. Future management will require mechanism-informed treatment algorithms that align therapeutic choice with dominant disease drivers while incorporating comorbidity management, de-escalation strategies and potential EBV-targeted preventive approaches to optimize outcomes across the entire disease course.\n\nID: 42481504\nTitle: Host-directed treatments for tuberculous meningitis utilizing a multi-platform approach across mouse and human models.\nAbstract: Tuberculous meningitis (TB meningitis) is a major cause of death and neurological deficit despite recommended antibiotic and corticosteroid treatments, primarily due to dysregulated neuroinflammation. Here, we investigate a diverse panel of 12 immunomodulatory drugs as host-directed treatments (HDTs) for TB meningitis utilizing a cross-species framework comprising studies in a mouse model of TB meningitis with clinical endpoints, and parallel mechanistic studies in a newly developed immune-vascularized human brain organoid model of TB meningitis and peripheral blood mononuclear cells (PBMCs) from patients with TB meningitis. Imatinib, bestatin, roflumilast, palacaparib, thalidomide/pomalidomide and semaglutide outperform the current standard of care by reducing mortality and/or neurological deficits in mice via suppression of neuroinflammation. Importantly, these HDTs significantly reduce microglial activation in Mycobacterium tuberculosis-infected human brain organoids and attenuate proinflammatory cytokines, particularly IFN\u03b3 within CD4+\u2009T-cells in patient-derived PBMCs. These findings highlight the potential of targeted HDTs to improve outcomes in TB meningitis and warrant clinical investigation.\n\nID: 42480452\nTitle: Microbial tryptophan-IPA axis mediates 6:2 chlorinated polyfluorinated ether sulfonate (6:2Cl-PFESA)-induced gut-brain dysfunction and neurobehavioral impairments.\nAbstract: Chlorinated polyfluoroalkyl ether sulfonic acids (Cl-PFESAs) are widely used substitutes for perfluorooctane sulfonate (PFOS) and are increasingly detected in environmental and human matrices, yet their neurobehavioral risks during early life remain poorly defined. Here, male C57BL/6J mice were orally exposed to F-53B (6:2Cl-PFESA; 0.1 or 1\u00a0mg/kg/day) during juvenility for four weeks. F-53B selectively impaired recognition memory and social novelty preference, whereas locomotor activity, anxiety-like behavior, and Y-maze working memory were largely preserved. Mechanistically, F-53B compromised intestinal barrier integrity, as evidenced by reduced occludin expression and disrupted ZO-1 continuity, accompanied by elevated circulating lipopolysaccharide (LPS) and a systemic pro-inflammatory cytokine shift. In parallel, the hippocampus exhibited microglial activation, enhanced inflammatory signaling, and reduced PSD95 expression, consistent with neuroinflammatory stress and synaptic vulnerability. Shotgun metagenomics revealed pronounced microbiome restructuring and network rewiring, while widely targeted metabolomics converged on a marked disruption of tryptophan metabolism, characterized by depletion of microbiota-derived indole metabolites, including indole-3-propionic acid (IPA), together with altered serotonin-related signatures. Notably, oral IPA supplementation rescued behavioral deficits and attenuated gut-brain inflammatory alterations, restoring intestinal aryl hydrocarbon receptor (AhR) nuclear translocation, reducing LPS and cytokine levels, and ameliorating hippocampal inflammatory phenotypes. Collectively, these findings provide mechanistic evidence that a microbiota-tryptophan metabolite-gut barrier-inflammation axis links exposure to substitute PFAS with selective neurobehavioral dysfunction, highlighting microbiota-derived metabolites as potential modulators of PFAS-associated neurotoxicity.\n\nID: 42479022\nTitle: VISTA Deficiency Exacerbates Autoimmune Uveitis by Promoting Microglial Activation via the TLR4/MyD88/NF-\u03baB Pathway.\nAbstract: VISTA, an immune checkpoint enriched in microglia, regulates inflammatory signaling. Given microglial activation drives autoimmune uveitis, we investigated whether VISTA protects against experimental autoimmune uveitis (EAU) by modulating retinal microglia. VISTA expression was analyzed by flow cytometry in active VKH patients and healthy controls. Functional studies in LPS/IFN-\u03b3-stimulated BV2 microglia used genetic knockdown/overexpression and modulating antibodies (13F3, MH5A). Activation status, cytokine secretion, migration, and TLR4/MyD88/NF-\u03baB signaling were assessed. An EAU mouse model received intravitreal adeno-associated virus-mediated VISTA overexpression, with severity evaluated clinically and histopathologically. VISTA was downregulated in circulating immune cells of VKH patients and in retinal microglia during EAU. In vitro, inflammatory stimuli reduced microglial VISTA. Its knockdown or blockade exacerbated microglial activation, pro-inflammatory mediator secretion (TNF-\u03b1, iNOS, COX2), and migration, while overexpression or agonism suppressed activation. Critically, intravitreal VISTA overexpression alleviated EAU severity. Mechanistically, VISTA deficiency potentiated activation by enhancing TLR4/MyD88/NF-\u03baB signaling. VISTA is a crucial gatekeeper of ocular immune homeostasis. Its downregulation promotes uveitis via microglial TLR4/MyD88/NF-\u03baB pathway activation, making VISTA signaling restoration a promising therapeutic strategy.\n\nID: 42478262\nTitle: Multifunctional Catechol-Functionalized Cellulose Hydrogels for the Minimally Invasive Treatment of Acute Optic Nerve Injuries.\nAbstract: Oxidative stress-induced retinal ganglion cell degeneration is a major pathological feature of acute optic nerve injury, yet current posterior-segment therapies are limited by poor local retention and repeated invasive administration. Here, we developed an injectable catechol-functionalized carboxymethyl cellulose hydrogel, CMCDA, as a bioadhesive and antioxidative intravitreal platform. Through dopamine grafting and oxidative crosslinking, CMCDA exhibited shear-thinning injectability, self-healing behavior, wet-tissue adhesion, controlled biodegradability, and good biocompatibility. In an optic nerve crush model, CMCDA significantly reduced retinal reactive oxygen species (ROS) accumulation, preserved retinal ganglion cells, promoted axonal regeneration, and attenuated microglial activation, with 7 wt% CMCDA showing the strongest therapeutic efficacy. Single-cell RNA sequencing further suggested that CMCDA reshaped the injured retinal microenvironment by suppressing apoptotic, oxidative-stress, and inflammatory pathways while supporting phototransduction-related programs. Importantly, these structural and molecular benefits were accompanied by improved visual function, as confirmed by visual cliff testing and electroretinography. Overall, CMCDA represents a multifunctional cellulose-based hydrogel platform for minimally invasive antioxidative neuroprotection, axonal repair, and functional recovery after optic nerve injury.\n\nID: 42477312\nTitle: Antidepressant-like effects of ketamine involve CX3CL1/CX3CR1 signaling-mediated synaptic plasticity in the mPFC.\nAbstract: Ketamine, a non-competitive N-methyl-D-aspartate acid (NMDA) receptor antagonist, produces rapid and sustained antidepressant actions, but the underlying molecular mechanism remains unclear. The CX3CL1/CX3CR1 signaling is closely related to mood disorders, and this study aims to investigate its role in ketamine's antidepressant actions. We pharmacologically (AZD8797, a selective CX3CR1 antagonist) and genetically (intra-mPFC microinjection with AAV-CX3CR1-siRNA) manipulated the CX3CL1/CX3CR1 signaling and investigated their effects on ketamine's antidepressant-like effects in mice treated with corticosterone (Cort), and observed changes in synaptic plasticity in response to these manipulations. We found that 24\u2009h after drug injection, ketamine (10\u2009mg/kg, i.p.) significantly reversed the Cort-induced depression-like behaviors, and inhibited the overexpression of pro-inflammatory cytokines and microglial activation. Ketamine significantly improved the Cort-induced impairment in the dendritic complexity and spine densities. In addition, our ELISA results showed that ketamine significantly inhibited the activation of CX3CL1/CX3CR1 signaling, and ketamine attenuated the upregulation of CX3CR1 and CX3CL1 expression in Cort-treated HT22 and BV2 cells in vitro. Furthermore, pretreatment with AZD8797 (0.8\u2009mg/kg, i.p., twice a week) completely blocked ketamine's antidepressant-like behavioral effects and eliminated ketamine-induced enhancement in the synaptic plasticity; intra-mPFC microinjection with AAV-CX3CR1-siRNA also prevented ketamine's behavioral effects and beneficial effects on the synaptic plasticity. These findings demonstrated that CX3CL1/CX3CR1 signaling-mediated synaptic plasticity played essential roles in ketamine's antidepressant-like effects, which opened a new door to targeting chemokines to improve depression symptoms.\n\nID: 42473795\nTitle: Small Extracellular Vesicles From Cardiomyocytes Activate Microglia Aggravating HFpEF.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is increasingly acknowledged as a major public health concern due to its complex pathophysiology, which involves neuroinflammation and sympathetic activation. The crosstalk between the heart and hypothalamic microglia in HFpEF, particularly the role of small extracellular vesicles (sEVs), remains insufficiently explored. We constructed an HFpEF model in mice by combining a long-term high-fat diet with the nitric oxide synthase inhibitor l-NAME (N[\u03c9]-nitro-l-arginine methyl ester). These mice exhibited microglial activation and hypothalamic inflammation. Microglial depletion with PLX3397 suppressed sympathetic activity and improved cardiac dysfunction in HFpEF. sEVs derived from the myocardium of HFpEF mice induced a proinflammatory M1 phenotype in microglia, leading to hypothalamic inflammation and sympathetic activation. Intraperitoneal injection of the sEV biogenesis inhibitor GW4869 reversed these changes in HFpEF mice. Similar pathological changes were observed in BV2 microglia treated with sEVs isolated from palmitic acid-treated HL-1 cardiomyocytes. Bioinformatic and RT-qPCR analyses revealed a notable upregulation of miR-200c-3p in sEVs derived from both HFpEF myocardial tissue and palmitic acid-treated HL-1 cardiomyocytes, as well as in microglia. A cardiomyocyte-specific miR-200c-3p sponge inhibited microglial activation, hypothalamic inflammation, and sympathetic activation in HFpEF mice. Conversely, a miR-200c-3p mimic exacerbated proinflammatory responses in BV2 cells, while a miR-200c-3p inhibitor prevented the transition to a proinflammatory phenotype. The antiinflammatory protein DUSP1 (dual-specificity phosphatase 1) was validated as a potential downstream target of miR-200c-3p in microglia. Our study reveals that HFpEF prompts cardiomyocytes to release sEVs enriched with miR-200c-3p, leading to hypothalamic inflammation and evoking sympathetic outflow, which in turn exacerbates cardiac dysfunction. Focusing on sEV-mediated communication between cardiomyocytes and microglia may offer a new therapeutic approach for HFpEF.\n\nID: 42473665\nTitle: Microglia heterogeneity in vascular dementia pathology.\nAbstract: Microglia exhibit remarkable phenotypic heterogeneity and functional plasticity across brain regions, time, and disease states. In vascular dementia (VaD)-the second most common dementia-cerebrovascular pathology drives distinct microglial activation states. This review synthesizes current understanding of microglial phenotypes in neurological disease, focusing on their contributions to VaD following vascular insults such as chronic cerebral hypoperfusion and stroke. Key VaD-associated phenotypes are described, including spatially segregated subsets in ischemic territories (ICAM and IPAM microglia), TREM1 + -activated microglia in hemorrhagic foci, and cytokine-responsive microglia (CRM) identified in human VaD brain. The molecular drivers of this heterogeneity are discussed, arguing for moving beyond the reductive M1/M2 dichotomy. The broader significance lies in a proposed framework for microglia-targeted therapeutic strategies, encompassing precision immunomodulation, antibody-mediated approaches, and in situ cellular reprogramming as promising avenues for future intervention.\n\nID: 42471426\nTitle: DNA Sensing and Neuroinflammation: Mechanistic Insights into cGAS-STING Biology and Therapeutic Translation in Age-Related Neurodegenerative Diseases.\nAbstract: Emerging evidence suggests that some of the earliest events contributing to neurodegeneration may occur upstream of classical proteinopathies, underscoring the urgency of identifying molecular pathways that link age-associated genomic instability to chronic neuroinflammation. Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.\n\nID: 42471076\nTitle: Antidepressant mechanism of Secoisolariciresinol in corticosterone-induced mice: PTGS2 as a key target of the cAMP-PKA-CREB-BDNF pathway.\nAbstract: Secoisolariciresinol (SECO), a natural monomer from Syringa oblata Lindl, remains unclear in antidepressant effects. This study aimed to investigate the antidepressant mechanism of SECO and clarify its core target and signaling pathway. Network pharmacology, molecular docking and corticosterone (CORT)-induced depressive mice model were applied. Behavioral tests, histological staining, ELISA and Western blot were performed for evaluation. Behavioral tests confirmed that SECO significantly improved depressive-like behaviors, increased sucrose preference and exploratory ability, and reduced immobility time. SECO ameliorated hippocampal CA1 neuronal morphological damage and neuronal loss. Treatment with SECO significantly decreased serum corticosterone (CORT) concentrations and hippocampal prostaglandin E2 (PGE2) levels. Concurrently, it elevated serum levels of key neurotransmitters, namely serotonin (5-HT), norepinephrine (NE), and dopamine (DA), and increased cyclic adenosine monophosphate (cAMP) content in the hippocampus. Mechanistically, SECO downregulated the expression of prostaglandin-endoperoxide synthase 2 (PTGS2) and activated the cAMP-PKA-CREB-BDNF signaling cascade. SECO alleviates neuroinflammation via PTGS2 inhibition and enhances neuronal plasticity by activating the cAMP/PKA-CREB-BDNF signaling pathway. These two synergistic effects contribute to the neuroprotective action of SECO, thereby ameliorating CORT-induced depressive-like behaviors in mice.\n\nID: 42471071\nTitle: Ginkgo biloba extract 50 alleviates memory and synaptic plasticity deficits by inhibiting neuroinflammation via the blockage of ATP-P2X7R axis in presenilin 1/2 conditional double knockout mice.\nAbstract: Ginkgo biloba L. has been widely utilized in traditional Chinese medicine for its potential to enhance memory-related functions. In traditional medical practices, it is also commonly prescribed for conditions associated with cognitive decline and age-related disorders. These ethnopharmacological uses are closely linked to neurodegenerative disorders, in which neuroinflammation plays a central role. Ginkgo biloba has shown anti-inflammatory and neuroprotective properties, yet its underlying mechanisms in modulating neuroinflammation are still not fully understood. Neuroinflammation is critically involved in cognitive impairment and neurodegenerative diseases, while therapeutic options remain limited. Ginkgo biloba extract 50 (GBE50) is a standardized formulation with potential neuroprotective properties. This study aimed to assess its effects on neuroinflammation-associated cognitive dysfunction and to clarify the mechanisms involved. Presenilin 1/2 conditional double knockout mice served as a cognitive impairment model, with behavioral tests used to evaluate cognitive function. The constituents of GBE50 were identified by UPLC-Q-TOF-MS, and ATP content was quantified using biochemical assays. The expression of P2X7 receptor, NLRP3 inflammasome-related proteins, inflammatory cytokines, and synaptic markers was determined at both mRNA and protein levels using qRT-PCR and Western blotting. Microglial activation and P2X7R distribution were assessed via immunofluorescence, and hippocampal synaptic plasticity was examined using electrophysiological recordings. Using UPLC-Q-TOF-MS, 51 compounds were characterized in GBE50, mainly flavonoids and terpene lactones, which are likely responsible for its biological activities. Treatment with GBE50 markedly alleviated cognitive impairment in PS cDKO mice. It downregulated P2X7R and key components of the NLRP3 inflammasome (NLRP3, NEK7, Caspase-1, and ASC), while also reducing the transcription of pro-inflammatory cytokines including Il-1\u03b2, Il-18, and Tnf-\u03b1. In parallel, GBE50 restored synaptic protein levels and improved long-term potentiation deficits. Collectively, our findings suggest that modulation of the ATP-P2X7R-NLRP3 axis contributes to the neuroprotective effects of GBE50 in AD, highlighting this pathway as a promising therapeutic target for preventing AD-related neurodegeneration.\n\nID: 42471032\nTitle: Sustainable next-generation prebiotics for brain health: microbiota-gut-brain axis in neurodegenerative and demyelinating diseases.\nAbstract: Neurodegenerative and neuroinflammatory diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis, are increasingly associated with disruption of the microbiota-gut-brain axis. Common alterations include reduced beneficial microbial taxa, impaired short-chain fatty acid production, intestinal and blood-brain barrier dysfunction, and sustained inflammatory responses. These findings support the development of microbiota-targeted dietary interventions. This review summarizes current evidence on polyphenols, bioactive peptides, and pectin-derived oligosaccharides (POS) as prebiotic or prebiotic-like compounds with potential activity through the microbiota-gut-brain axis. Particular attention is given to structure-function relationships, host-microbe interactions, and the sustainable recovery of these compounds from food by-products. Preclinical studies suggest that these bioactives may reduce microglial activation, improve mitochondrial function, strengthen intestinal and blood-brain barrier integrity, and enhance cognitive or motor performance. Early clinical studies also indicate possible benefits on mood, selected cognitive outcomes, metabolic regulation, and inflammatory biomarkers, although evidence remains limited. Microbiota-derived metabolites from polyphenols, such as urolithins, together with glycomacropeptide and POS, appear to be key mediators. However, clinical validation in major neurodegenerative diseases remains fragmented. Standardized formulations, mechanistic trials, harmonized endpoints, and precision-nutrition strategies are required to confirm their therapeutic potential.\n\nID: 42470955\nTitle: Jiao-tai-wan suppresses ferroptosis induced by heart-kidney disharmony insomnia by regulating the PDE4D/BDNF signaling pathway.\nAbstract: Jiao-tai-wan (JTW) is a classic formula for Heart-Kidney Disharmony insomnia, yet its mechanism in hippocampal neurons remains unclear. To investigate whether JTW ameliorates insomnia-induced hippocampal neuronal damage by inhibiting ferroptosis and elucidate the underlying mechanisms. UPLC-Q-TOF/MS analyzed JTW constituents. Network pharmacology and molecular docking predicted core targets. A mouse insomnia model was established using PCPA combined with MMPM. Behavioral tests, pathological examinations, and ferroptosis markers were evaluated. In vitro, HT22 cells underwent IKE-induced ferroptosis to validate Jiao-tai-wan drug-containing serum (JTWS) and the PDE4D inhibitor Zatolmilast (ZAT). 413 compounds were identified in JTW, with 47 predicted to penetrate the blood-brain barrier. Network pharmacology, molecular docking, and molecular dynamics simulations predicted PDE4D and BDNF as core targets. In vivo, JTW ameliorated cognitive deficits, attenuated hippocampal neuronal damage, and restored mitochondrial ultrastructure. Mechanistically, JTW downregulated Ptgs2 expression, upregulated Gpx4, Fth1, and Acsl3 expression, reduced lipid peroxidation and iron accumulation, while simultaneously suppressing Pde4d and restoring Bdnf levels. In vitro, ZAT mimicked the anti-ferroptotic effects of JTW. JTW inhibits hippocampal neuronal ferroptosis through multi-target regulation, ameliorating insomnia-related neuronal damage and providing a molecular basis for its traditional efficacy in restoring Heart-Kidney communication.\n\nID: 42469847\nTitle: A BRD4/p300/SP1 epigenetic cascade drives microglial P2X4R transcription and promotes neuropathic pain.\nAbstract: Persistent upregulation of the purinergic receptor P2X4R is strongly associated with microglial activation in neuropathic pain, yet the epigenetic mechanisms linking chromatin remodeling to its dysregulation remain unclear. Here, we delineate a hierarchical epigenetic cascade that promotes transcriptional activation of P2X4R in spinal microglia following nerve injury. In a mouse spared nerve injury (SNI) model, microglial activation was accompanied by increased expression of P2X4R and the histone acetyltransferase p300, together with enhanced histone acetylation (H3K9ac, H3K27ac, H4K5ac, and H4K8ac) and increased chromatin accessibility at the P2rx4 promoter. Microglia-specific deletion of p300 blunted injury-induced histone acetylation and suppressed P2X4R upregulation. We further demonstrate that the acetylation reader BRD4 is recruited to these regions and cooperates with the transcription factor SP1 to drive P2rx4 transcription, supported by chromatin analyses revealing inducible assembly of a BRD4-p300-SP1 axis. Disruption of this cascade via p300 inhibition (C646) or BRD4 blockade (JQ1) attenuated spinal neuroinflammation and alleviated nociceptive hypersensitivity. Notably, reactivation of P2X4R by BzATP largely reversed the analgesic effects of BRD4 inhibition, establishing P2X4R as a critical downstream effector. Collectively, these findings support a p300-BRD4-SP1 epigenetic cascade linking chromatin remodeling to microglia-mediated neuropathic pain, highlighting this pathway as a potential therapeutic target.\n\nID: 42469820\nTitle: CCR1 signaling as a common injury pathway in retinal degeneration.\nAbstract: Inflammation is a key driver of atrophic Age-Related Macular Degeneration (aAMD), and also plays a role in Inherited Retinal Degenerations (IRDs), two major causes of irreversible visual loss. We previously demonstrated that the C-C chemokine receptor type 1 (CCR1) is upregulated in monocytes from AMD patients, and that it mediates the recruitment of neurotoxic macrophages and activates M\u00fcller glial cells in rodent model of photic retinal injury. Here we report that CCR1 is expressed in M\u00fcller glia in eyes affected by AMD and that variants in CCR1 are potentially associated with the rate of macular atrophy progression in AMD. We also show that Ccr1 deletion is associated with reduced inflammation, and with rescue of photoreceptor integrity and function in Crb1rd8/rd8 mice and in Pde6brd10 mice, two models of genetically-driven retinal degeneration. Finally, we demonstrate that treatment with small molecule CCR1 antagonists delayed photoreceptor loss in Pde6brd10 mice. These data suggest that CCR1 is a mediator of retinal inflammation and injury in different forms of retinal degeneration, and that CCR1 may serve as a novel therapeutic target for atrophic AMD and IRDs.\n\nID: 42469617\nTitle: IRAK-M attenuates pain hypersensitivity and anxiety-like behaviors in a nitroglycerin-induced chronic migraine mouse model with concomitant reductions in microglial activation and neuroinflammation.\nAbstract: Chronic migraine (CM) is a disabling neurological disorder in which neuroinflammatory mechanisms and central sensitization are thought to contribute to disease pathophysiology. Interleukin-1 receptor-associated kinase M (IRAK-M), which is predominantly expressed in microglia in the central nervous system (CNS), is an endogenous negative regulator of innate immune signaling. Previous studies have linked IRAK-M to the restraint of Toll-like receptor 4 (TLR4) signaling and NLR family pyrin domain-containing 3 (NLRP3) inflammasome-related responses. However, the role of IRAK-M in CM-related pathophysiology and associated neuropsychiatric comorbidities remains unclear. This study aimed to investigate the function of IRAK-M and its underlying molecular mechanisms in a mouse model of chronic migraine. Mice were repeatedly given intraperitoneal injections of nitroglycerin (NTG; 10\u00a0mg/kg) to create a chronic migraine model. Mechanical and thermal sensitivity were assessed using von Frey filaments and the hot-plate test, respectively; light aversion and anxiety-like behaviors were evaluated using the light-aversion test, open-field test, and elevated plus-maze test. To further clarify the role of IRAK-M, both transgenic genetic engineering approaches and adeno-associated virus (AAV)-mediated expression strategies were employed. The underlying molecular mechanisms were further investigated using quantitative PCR, immunoblotting, immunofluorescence, and three-dimensional reconstruction. Repeated administration of NTG increased IRAK-M protein in the trigeminal nucleus caudalis (TNC). IRAK-M deficiency exacerbated mechanical and thermal hyperalgesia, increased c-Fos and CGRP expression, and enhanced microglial activation; these changes were accompanied by increased TLR4/NF-\u03baB-related signaling, NLRP3 inflammasome activation, and GSDMD cleavage. Conversely, TNC-targeted IRAK-M overexpression attenuated pain hypersensitivity and anxiety-like behavioral alterations and was accompanied by corresponding reductions in neuroinflammatory molecular and cellular readouts. These findings support IRAK-M as an important regulator of central sensitization and neuroinflammatory responses in a chronic migraine model. Our findings identify IRAK-M as an important preclinical regulator of microglial reactivity and neuroinflammatory responses in the NTG-induced chronic migraine model. IRAK-M manipulation was accompanied by bidirectional changes in TLR4/NF-\u03baB- and NLRP3/GSDMD-related signaling, pain hypersensitivity, and anxiety-like behavioral alterations. These findings provide a preclinical rationale for further investigation of IRAK-M-related neuroimmune signaling in migraine. Not applicable.\n\nID: 42469568\nTitle: Nanomedicine targeting neuroinflammatory pathways in Alzheimer's disease: a new frontier in inflammopharmacology.\nAbstract: Alzheimer's disease (AD) is a multifactorial neurodegenerative illness characterized by progressive cognitive impairment, synaptic compromise, and relentless neuroinflammation. Increasing evidence suggests that neuroinflammatory cascades orchestrated by microglial activation, astrocytic malfunction, cytokine hyperproduction, and inflammasome signalling are at the core of AD pathogenesis. Conventional anti-amyloid and cholinergic treatments are only symptomatic and neglect the inherent neuroimmune dysregulation. Nanomedicine is a revolutionary frontier in inflammopharmacology, which enables the accurate modulation of neuroinflammatory circuits and enhanced brain delivery of medicines. Nanocarriers designed by engineering, including liposomes, polymeric nanoparticles, dendrimers, and exosomes, allow for targeted delivery across the BBB, increase drug bioavailability, and provide controlled release. The nano-systems are capable of inhibiting pro-inflammatory signalling, such as NF-\u03baB and MAPK pathways, reducing oxidative stress, and enhancing microglial M2 polarization and thus restoring neuronal homeostasis. Recent developments in surface-functionalized and stimuli-responsive nanoplatforms further enable active targeting through receptor-mediated pathways and theranostic imaging in real-time. Comparative studies show that interventions based on nanocarrier-based therapies enhance therapeutic efficacy and safety profiles in preclinical AD models. Future directions include integrating AI-driven nano-design, gene and siRNA delivery, and precision neuropharmacology to enable personalized anti-inflammatory therapies. Substantial progress, translational challenges remain regarding long-term biocompatibility, large-scale production, and clinical validation. Nanomedicine against neuroinflammatory pathways represents a new paradigm for Alzheimer's treatment, linking molecular pharmacology and sophisticated nanotechnology to next-generation neuroinflammatory medicine.\n\nID: 42467957\nTitle: New horizons in HIV neuropathogenesis: thinking beyond the brain.\nAbstract: Neurocognitive disorders and neuropathology continue to affect a subset of people with HIV (PWH) despite long-term viral suppression with antiretroviral therapy (ART). The mechanisms driving persistent neuropathology remain incompletely defined, and current therapeutic options are largely nonspecific and patient-dependent. This review analyses emerging evidence on HIV-associated neuropathology in ART-suppressed PWH, with a particular focus on the role of the gut-brain axis. Recent studies demonstrate that the CNS is a stable and transcriptionally active tissue reservoir, which may sustain chronic microglial activation, pro-inflammatory signalling, and synaptic injury. In parallel, accumulating evidence implicates systemic inflammation and gut barrier dysfunction as key contributors to neuroinflammation, linking microbial translocation and gut-brain axis perturbations to cognitive decline in PWH. Furthermore, persistent gut inflammation may result in enteric nervous system (ENS) dysfunction and aberrant signals that directly results in neuroinflammation and neuropathology. These mechanistic insights have driven evaluation of adjunctive strategies targeting HIV transcription and inflammatory pathways as potential approaches to limit neuropathogenesis. Neuropathology in ART-suppressed PWH arises from convergent processes involving CNS HIV reservoirs, myeloid-driven neuroinflammation, systemic immune activation and gut-derived injury, rather than residual brain infection alone. Defining the relative contribution of these pathways in PWH and developing CNS-penetrant interventions that silence viral transcription, restore gut integrity and dampen systemic inflammation, will be critical to preventing and treating HIV-associated neuropathology.\n\nID: 42467315\nTitle: Decoding the PI3K/Akt/mTOR-JAK/STAT signaling axis in multiple sclerosis: mechanistic crosstalk and therapeutic opportunities.\nAbstract: Multiple Sclerosis (MS) is a chronic immune-mediated neurodegenerative disorder characterized by demyelination, axonal injury, and progressive neurological dysfunction. Emerging evidence identifies the phosphoinositide-3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/Akt/mTOR) and Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathways as interconnected regulators of neuroinflammation and immune dysregulation in MS. This review critically examines the mechanistic crosstalk between these signaling networks and their contribution to disease progression. Dysregulated PI3K/Akt/mTOR signaling influences T-cell activation, immunometabolic reprogramming, autophagy, and oligodendrocyte survival, whereas aberrant activation of the JAK2/STAT3 axis promotes Th17-cell differentiation, cytokine amplification, and sustained inflammatory responses within the central nervous system. Importantly, convergence between Th17/STAT3 signaling and PI3K/Akt-mediated metabolic pathways establishes a regulatory network that enhances microglial activation, blood-brain barrier disruption, and neuronal injury. The review further highlights the context-dependent role of mTOR signaling, which may simultaneously support remyelination and oligodendrocyte maturation while contributing to neurodegeneration when excessively activated. In addition to immune-cell-mediated mechanisms, emerging evidence demonstrates critical contributions of neuronal, glial, endothelial, and oligodendrocyte precursor cell signaling to MS pathology. Preclinical and clinical findings indicate that pharmacological modulation of these pathways can attenuate inflammatory responses and improve neuroprotection; however, therapeutic translation remains challenging because of their dual physiological and pathological functions. Collectively, this review provides an integrated perspective on PI3K/Akt/mTOR-JAK/STAT signaling interactions and highlights cell-specific molecular targets that may facilitate the development of more precise therapeutic strategies for MS.\n\nID: 42467293\nTitle: Resveratrol and neuroprotection: modulation of cellular dynamics and signaling networks in neurodegenerative diseases.\nAbstract: Progressive loss of neurons, oxidative stress, neuroinflammation, and mitochondrial dysfunction are hallmarks of neurodegenerative diseases (NDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Resveratrol, a polyphenolic phytoalexin mainly found in grapes and red wine, is a promising treatment candidate due to its diverse biological effects and neuroprotective properties. This review demonstrates the regulatory effects of resveratrol on cellular signaling pathways linked to NDs and its neuroprotective mechanisms. Resveratrol enhances neuronal survival, boosts mitochondrial biogenesis, and mitigates oxidative stress by affecting key molecular pathways, including SIRT1/AMPK, PI3K/Akt, MAPK, and Nrf2/ARE. The PI3K/Akt and ERK1/2 pathways promote neuronal regeneration by modulating pro-apoptotic and anti-apoptotic factors. Resveratrol inhibits NF-\u03baB, reducing cytokine release and microglial activation, thereby exhibiting anti-inflammatory properties. It improves cognitive function, synaptic plasticity, and neuronal survival. Despite an increasing pharmacological profile, its practical applicability is limited by inadequate bioavailability, rapid metabolism, and restricted brain penetration. This review demonstrates resveratrol's effect on interconnected signaling networks related to neurodegeneration. We critically compare evidence from preclinical and clinical studies, demonstrating both therapeutic potential and translational limitations. Emerging nanotechnology-based delivery strategies are demonstrated to overcome bioavailability and blood-brain barrier penetration challenges. These insights provide a translational perspective for the future development of resveratrol-based interventions in NDs.\n\nID: 42464680\nTitle: Sedanolide alleviates LPS\u2011induced depressive\u2011like behaviors by modulating the C3a/C3aR signaling axis and microglial glycolysis.\nAbstract: A total of ~30% of patients with depression do not respond to pharmacological treatment. Sedanolide (SD) is a compound derived from Chinese medicinal herbs and has structural features associated with anti\u2011inflammatory activity. However, its effect on depressive disorders remains unclear. The present study aimed to examine the therapeutic effects of SD in lipopolysaccharide (LPS)\u2011induced depressive disorder and to investigate the underlying mechanisms. An LPS\u2011induced male mouse model of depressive\u2011like behavior was used to evaluate the therapeutic effect and underlying mechanisms of SD. The mRNA levels of pro\u2011inflammatory cytokines and the activation state of microglia in the medial prefrontal cortex (mPFC) were assessed. In addition, high\u2011throughput RNA sequencing was performed as an unbiased transcriptomic screen to identify differentially expressed genes. Western blotting and ELISA assays were then used to validate the expression and activation levels of key candidate molecules within the identified pathways. BV\u20112 cell line was utilized to assess the aerobic glycolysis in vitro by metabolic extracellular flux analysis. Finally, the selective C3aR antagonist SB290157 was administered to determine whether the effects of SD depended on the downstream C3a/C3aR signaling cascade. SD treatment significantly increased the sucrose preference and reduced immobility time in both the tail suspension test and the forced swimming test in LPS\u2011treated mice. Mechanistically, SD attenuated LPS\u2011induced neuroinflammation and microglial activation in the mPFC. High\u2011throughput RNA sequencing identified C3 and matrix metalloproteinase\u20119 as key transcriptional targets potentially involved in the effects of SD. Crucially, both in vitro and in vivo ELISA assays revealed that SD directly suppressed complement C3 activation by inhibiting its proteolytic cleavage into the active C3a fragments. Furthermore, SD reduced abnormal microglial aerobic glycolysis and restored mitochondrial respiration in vitro. By contrast, pharmacological inhibition of C3aR completely abolished protective effects of SD on behavioral despair, anhedonia, neuroinflammation and metabolic reprogramming. These findings indicate that SD alleviates depressive\u2011like behaviors. The C3a/C3aR signaling axis appears to play a critical role in mediating its anti\u2011inflammatory and anti\u2011glycolytic effects.\n\nID: 42464555\nTitle: Astrocyte exosomes shield retina from ischemia via CaMKII-autophagy.\nAbstract: Retinal ischemia-reperfusion (RIR) injury impairs vision through microvascular damage and inflammation. While astrocyte-derived exosomes (ADEs) offer neuroprotection, their role in protecting retinal microvasculature is unclear. This study investigates ADEs' effects on retinal microvascular endothelial cells (RMECs) in RIR. ADEs were isolated from astrocytes. Mouse RIR and cellular oxygen-glucose deprivation/reoxygenation (OGD/R) models were used. We assessed ADEs' impact on retinal microcirculation, microglial activation, and RMEC function. The roles of neurogranin and the CaMKII-autophagy pathway were examined using inhibitors. ADEs, rich in neurogranin, alleviated RIR-induced microvascular damage and suppressed OGD/R-triggered pro-inflammatory microglial activation. This was associated with increased neurogranin, CaMKII phosphorylation, and autophagy in microglia. Consequently, ADEs counteracted the harmful effects of activated microglia on RMEC proliferation, migration, and tube formation. Inhibiting CaMKII or autophagy blocked ADEs' protective benefits without altering neurogranin, placing the CaMKII-autophagy axis downstream. ADEs protect RMECs from RIR injury by modulating microglial responses via a neurogranin-CaMKII-autophagy mechanism, revealing their therapeutic potential for retinal microvascular protection.\n\nID: 42463677\nTitle: Repurposing the antiplatelet drug prasugrel for Parkinson's disease: evidence of neuroprotective effects and proteomic profiles.\nAbstract: Chronic neuroinflammation is a hallmark pathological feature of Parkinson's disease (PD) that contributes to progressive neuronal death. Current medications are largely palliative, underscoring the need for alternative therapeutic strategies. Drug repurposing offers a cost-effective and time-efficient approach by leveraging established safety profiles. Here, we screened the U.S. Food and Drug Administration-approved drug library using two in vitro PD models: 1-methyl-4-phenylpyridinium (MPP+)-induced primary cortical neurons and lipopolysaccharide (LPS)-induced BV2 microglial cells. Proteomic alterations following prasugrel treatment were profiled using Ingenuity Pathway Analysis. Neuroprotective effects were validated by biochemical assays and further confirmed in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model. We found that prasugrel, an antiplatelet drug used for acute coronary syndrome, exhibited significant neuroprotective and anti-inflammatory effects. It reduced the expression of apoptosis- and inflammation-related proteins, inhibited mitogen-activated protein kinase (MAPK)-mediated neuronal death and suppressed nuclear factor kappa B (NF-\u03baB)-dependent inflammatory signaling. In vivo, prasugrel administration preserved dopaminergic neurons and improved motor performance in MPTP-treated mice. These findings demonstrate that prasugrel mitigates neuronal apoptosis and microglial activation through modulation of MAPK and NF-\u03baB signaling pathways, supporting its development as a repurposed therapeutic candidate for PD.\n\nID: 42459360\nTitle: Micro- and nanoplastics as environmental modifiers of neuroimmune dysfunction in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons and the aggregation of \u03b1-synuclein, with increasing evidence implicating environmental factors and neuroimmune dysfunction in its pathogenesis. Micro- and nanoplastics (MNPs), ubiquitous environmental pollutants generated from plastic degradation, have recently emerged as potential biological stressors capable of entering the human body and accumulating in sensitive tissues, including the brain. Due to their small size, environmental persistence, and capacity to carry toxic additives and environmental contaminants, these particles can induce oxidative stress, impair mitochondrial and lysosomal function, and activate both innate and adaptive immune responses. This review summarizes current evidence linking microplastic exposure to neuroinflammatory processes relevant to PD, with a particular focus on microglial activation, astrocyte reactivity, peripheral immune involvement, and dysfunction of the gut-brain axis. Although a direct causal relationship between MNPs and PD has yet to be established, and direct human epidemiological evidence linking MNP exposure to PD is currently absent, the immunotoxic and neuroinflammatory effects of these particles suggest that they may contribute to disease susceptibility and progression. Elucidating the interactions between MNPs and neuroimmune pathways may help refine current frameworks linking environmental exposure, neuroimmune dysfunction, and PD susceptibility.\n\nID: 42458823\nTitle: A TREK-1/AQP4/TRPA1/BDNF Signaling Axis Is Associated With Astrocytic Volume Transients, Synaptic Plasticity, and Spatial Memory.\nAbstract: Astrocytes, known for their support roles, are emerging as active participants in synaptic plasticity and cognitive functions. Astrocytes actively regulate synaptic plasticity and memory through dynamic volume transients. Our previous research identified several key molecules, including TREK-1, TRPA1, and Best1 ion channels, as well as the gliotransmitter BDNF, as critical components of astrocytic volume transients. However, the precise mechanisms by which these volume transients influence synaptic plasticity and memory remain poorly understood. In this study, we investigate the roles of TREK-1 and TRPA1 in astrocytic volume dynamics and their downstream effects. Our findings, based on intrinsic optical signal imaging, electrophysiology, and behavioral assays, support a model in which neuronal stimulation induces astrocytic swelling, initiated by K+ uptake through TREK-1 channels and regulated by Ca2+ influx via TRPA1 channels. This swelling is closely associated with short- and long-term potentiation (LTP), and exogenous BDNF restores LTP under conditions of calcium sequestration during astrocytic calcium clamping experiments. Disruption of ion channels associated with astrocytic volume transients leads to significant impairments in spatial memory, as demonstrated by deficits in object-place recognition and passive avoidance tasks. Moreover, these channels contribute to the regulation of synaptic plasticity. These findings implicate astrocytic volume transients and BDNF as pivotal modulators of synaptic plasticity and memory, as well as potential therapeutic targets for addressing memory dysfunctions.\n\nID: 42458669\nTitle: Daidzein Prevents Stress-Induced Synaptic Plasticity Impairment and Behavioral Dysfunction via ERK/CREB/BDNF Signaling Pathway.\nAbstract: Chronic stress (CS) represents a pivotal environmental trigger for depression. It induces depression-like behaviors primarily by disrupting hypothalamic-pituitary-adrenal (HPA) axis homeostasis and impairing hippocampal synaptic plasticity. Flavonoids are abundant in human diet and possess significant neuroprotective potential. We screened a library of 339 flavonoid compounds. Daidzein (DAI) was identified as the lead compound. Subsequently, in rats subjected to chronic restraint stress (CRS), DAI administration effectively ameliorated depression-like behaviors, and attenuated hippocampal histopathological damage. Network pharmacology and molecular docking analyses suggested that ERK-related signaling may be involved in the protective effects of DAI, and molecular dynamics simulations supported the stability of the DAI-ERK2 complex. Furthermore, DAI activated the ERK/CREB/BDNF signaling cascade, an effect that was partially reversed by ERK inhibitor intervention. Notably, DAI also enhanced dendritic complexity and spine density in hippocampus. In summary, our study demonstrates that DAI alleviates stress-induced synaptic plasticity damage through the ERK/CREB/BDNF signaling pathway.\n\nID: 42458515\nTitle: FPR2 deficiency alleviates LPS-induced depressive-like behaviors in mice by suppressing the microglial CSF1/NLRP3 inflammasome pathway.\nAbstract: Depression is one of the most prevalent psychiatric disorders worldwide, yet its pathogenesis remains unclear. Here, we aimed to investigate the effects of formyl peptide receptor 2 (FPR2), a key regulator of innate immunity and inflammation, on lipopolysaccharide (LPS)-induced depression-related behaviors in mice after intraperitoneal administration, and to elucidate its regulatory mechanisms in microglia. FPR2 knockout (Fpr2-/-) significantly attenuated LPS-induced depressive and anxiety-like behaviors in mice. LPS markedly increased FPR2 expression in microglia of the prefrontal cortex (PFC) and hippocampus, while only a minimal increase was observed in neurons. FPR2 deficiency alleviated LPS-induced microglial activation and reduced neuronal synaptic alterations. RNA sequencing and validation experiments confirmed that FPR2 deletion substantially decreased LPS-induced microglial NLRP3 inflammasome activation and IL-1\u03b2 levels in the brain. Mechanistically, FPR2 regulated downstream NLRP3 activation by modulating CSF1, and FPR2/CSF1 activation was governed by its upstream ligand, serum amyloid A (SAA). Analysis of public clinical datasets revealed that SAA1 levels were significantly upregulated in the orbital ventral PFC of patients with major depressive disorder (MDD) and in the plasma of patients with late-life depression. These findings demonstrate that the SAA/FPR2/CSF1/NLRP3 pathway mediates LPS-induced depressive-like behaviors by regulating microglial activation and neuroinflammation.\n\nID: 42457861\nTitle: Aspirin alleviates long-term high-fat diet-induced depressive-like behavior in male mice via suppressing arachidonic acid-mediated microglial activation and neuroinflammation.\nAbstract: While Western dietary patterns are increasingly linked to neuropsychiatric disorders, the causal mechanisms by which chronic high-fat diet (HFD) contributes to depression remain elusive. Here, we demonstrate that prolonged (\u2009\u2265\u200910 weeks) HFD exposure in mice robustly induces depressive-like behaviors, phenocopying chronic stress models. Integrating multi-omics and targeted lipidomics, we reveal that HFD-induced behavioral deficits are underpinned by gut microbiota dysbiosis and a profound disruption of polyunsaturated fatty acid (PUFA) homeostasis. This disruption is characterized by a surge in pro-inflammatory \u03c9-6 metabolites, particularly arachidonic acid (AA), alongside a concomitant reduction in anti-inflammatory \u03c9-3 metabolites. These lipid perturbations strongly correlate with marked microglial activation and elevated pro-inflammatory cytokine levels (IL-6, TNF-\u03b1, CCL2) in the prefrontal cortex and hippocampus. Functionally, AA supplementation alone was sufficient to recapitulate depressive-like behaviors in vivo and, through neuron-microglia co-culture assays, directly induce pro-inflammatory microglial activation, NF-\u03baB pathway upregulation, and subsequent synaptic impairment in vitro. Critically, therapeutic intervention with aspirin, a dual COX-1/COX-2 inhibitor, effectively reversed HFD-induced behavioral deficits. This protection was mediated by a dual mechanism: directly inhibiting microglial hyperactivation and normalizing the neuroinflammatory milieu by suppressing the biosynthesis of pro-inflammatory \u03c9-6-derived prostanoids, including AA and 12-HETE. Collectively, our findings identify AA as a critical etiological link between HFD and neuroinflammation, establishing a mechanistic framework for \"metabolic depression.\" The profound therapeutic efficacy of aspirin validates the AA metabolic pathway, specifically COX-1/COX-2, as a promising and targetable node for intervention, offering translational insights for the burgeoning field of nutritional psychiatry.\n\nID: 42457123\nTitle: Enavogliflozin alleviates motor deficits in rotenone-induced Parkinson's disease mice via attenuation of oxidative stress and neuroinflammation as well as activation of the SIRT1/PINK1/Parkin pathway.\nAbstract: Parkinson's disease is an age-related neurodegenerative disorder characterized by the progressive degeneration of nigrostriatal dopaminergic neurons. Enavogliflozin, a novel sodium-glucose cotransporter 2 (SGLT2) inhibitor, has recently been demonstrated to exert neuroprotective effects. However, whether enavogliflozin can ameliorate motor behavioral deficits in Parkinson's disease currently remains unclear. To this end, this study aimed to investigate the neuroprotective effects of enavogliflozin on Parkinson's disease and explore its underlying molecular mechanisms. We established a Parkinson's disease model using rotenone-induced C57BL/6 mice (1.5\u202fmg/kg/d, 3 weeks, i.p.) to investigate the neuropharmacological modulation effects of enavogliflozin treatment (0.1 and 1\u202fmg/kg/d, 3 weeks, p.o., 2\u202fh after rotenone injection) on Parkinson's disease from the perspectives of motor behavioral evaluation, pathological changes, oxidative stress, neuroinflammation, and SIRT1/PINK1/Parkin signaling pathways in specific brain regions. The results revealed that enavogliflozin alleviated neuropathological alterations of the substantia nigra, upregulated tyrosine hydroxylase and dopamine transporter expression in nigrostriatal dopaminergic neurons, and improved motor behavioral deficits. Administration of enavogliflozin further significantly reduced the levels of inflammatory cytokines (IL-6 and TNF-\u03b1), microglial activation, and oxidative damage in rotenone-induced Parkinson's disease mice. Moreover, we found that enavogliflozin activated PINK1/Parkin-mediated mitophagy by SIRT1 signaling pathway. In conclusion, enavogliflozin ameliorates motor dysfunction in rotenone-induced Parkinson's disease mice by attenuating oxidative stress, inhibiting neuroinflammation, and activating SIRT1/PINK1/Parkin pathway. These findings support a neuroprotective and preventive role for enavogliflozin in Parkinson's disease.\n\nID: 42457059\nTitle: Ischemia-induced p300-dependent histone lactylation activates an AP-1-SPP1 program in microglia to exacerbate ischemic brain injury.\nAbstract: Cerebral ischemia causes profound metabolic disruption, but how ischemia-associated metabolites reshape microglial chromatin and inflammatory function remains unclear. Here we identify histone lactylation as an epigenetic mechanism linking ischemic metabolic stress to pathogenic microglial activation. In transient middle cerebral artery occlusion mice and oxygen-glucose deprivation/reperfusion models, ischemic stress robustly increased H3K18la and H4K12la in microglia. CUT&Tag profiling showed widespread remodeling of both lactylation landscapes, with gained peaks preferentially associated with inflammatory, chemotactic, migratory and efferocytic programs. Integration with microglial RNA sequencing identified a concordantly activated gene network enriched for TNF, NF-\u03baB, IL-17 and cytoskeletal regulatory pathways, with Spp1 emerging as a prominent effector linked to ischemia-induced lactylation. Motif enrichment and locus-level analyses implicated AP-1-associated regulatory elements, and ChIP-qPCR confirmed increased H3K18la and H4K12la at Fos and Spp1 regulatory regions after ischemia-like stress. Mechanistically, p300 depletion or inhibition reduced H3K18la/H4K12la accumulation, impaired AP-1-associated promoter engagement, and suppressed Fos, Spp1 and chemokine induction. Non-lactylatable H3K18R and H4K12R mutants attenuated Fos-Spp1 transcription and microglial migration, supporting cooperative regulation by these two marks. Functionally, microglia-specific Spp1 deletion reduced inflammatory microglial activation, neuronal apoptosis and long-term neurological deficits after ischemic injury. Pharmacological inhibition of p300 or AP-1, and SPP1 neutralization, similarly limited neuroinflammation and improved sensorimotor and cognitive recovery. Together, our findings define a lactate-p300-AP-1-SPP1 axis that couples ischemic metabolism to microglial chromatin remodeling and post-stroke neuroinflammatory injury.\n\nID: 42456994\nTitle: Modulating hepatic hypoxanthine metabolism relieve metabolic stress-related neurovascular resilience disturbance via the liver-brain axis.\nAbstract: Unhealthy lifestyles promote brain aging, but their mechanisms remain unclear. The liver-brain axis acts as a key mediator of brain dysfunction and warrants investigation in lifestyle-induced brain aging. To elucidate how the liver-brain axis mediates lifestyle-triggered neurovascular resilience disturbance and associated brain aging phenotypes, and identify effective anti-aging intervention targets. A combination of in vivo animal models, multi-omics analyses, computational simulation, brain organoid experiments, and molecular biology techniques to explore the mechanism of liver-brain axis mediates lifestyle-triggered neurovascular resilience disturbance and associated brain aging phenotypes and verify the efficacy of Bazi Bushen capsule (BZBS) intervention. A mouse model established using a combined high-fat/high-sugar diet and circadian disruption (HFHS/CD). Cognitive function and anxiety-like behaviors were evaluated. Multi-omics analyses were performed, and liver-brain axis/hypoxanthine signals were verified via computational simulation and brain organoids. Active ingredient targets were identified by molecular docking, drug affinity responsive target stability, and validated by biolayer interferometry. HFHS/CD induced cognitive decline and anxiety accompanied by apparent brain aging-related phenotypes, which were alleviated by nicotinamide mononucleotide (NMN) and BZBS. Dysregulated hepatic hypoxanthine metabolism under metabolic stress contributed to neurovascular homeostasis disturbance, characterized by compromised BBB integrity and excessive microglial activation. In vitro experiments further indicated that elevated hypoxanthine levels were involved in endothelial senescence, potentially through P2X7-dependent suppression of NRF2-governed glutathione metabolism. BZBS acted through multiple targets: imperatorin/isopimpinellin regulated hepatic purine nucleoside phosphorylase (PNP)/hypoxanthine phosphoribosyltransferase 1 (HPRT1) to reduce hypoxanthine, while osthole/schizandrin A maintained endothelial integrity. Aberrant hypoxanthine metabolism induced by unhealthy lifestyles may disrupt neurovascular homeostasis through the liver-brain axis and contribute to the occurrence of brain aging phenotypes. BZBS improves age-related brain dysfunction by targeting hypoxanthine metabolism and protecting endothelial function, representing a promising intervention.\n\nID: 42456856\nTitle: Selenium nanoparticles modulate gut-brain axis via NRF2 to attenuate Parkinsonian neurotoxicity.\nAbstract: Parkinson's disease (PD) is characterized by progressive dopaminergic neurodegeneration driven by mitochondrial dysfunction, oxidative stress, neuroinflammation, and impaired gut-brain communication. Here, we report a biogenic selenium nanoparticle (Se-NP) platform derived from mussel tissue and demonstrate its nano-enabled neuroprotective efficacy in a rotenone-induced zebrafish model of Parkinsonian neurotoxicity. Selenium was extracted from the tissue of Perna viridis (mussel) and used for the biogenic synthesis of Se-NPs through a green reduction approach under controlled conditions. The mussel-derived Se-NPs exhibited high redox-buffering capacity, enabling efficient attenuation of rotenone-induced oxidative stress, lipid peroxidation, and nitric oxide accumulation. Se-NP treatment preserved dopaminergic neuronal architecture, reduced microglial activation, and maintained gut epithelial integrity, indicating coordinated neuro-intestinal protection. Mechanistically, Se-NPs activated NRF2-driven antioxidant signaling through upregulation of NFE2L2a and HMOX1a and suppression of KEAP1a, thereby restoring endogenous antioxidant defences. At the neurovascular interface, Se-NPs enhanced blood-brain barrier integrity by upregulating tight junction proteins Claudin-5a and ZO-1, linking redox regulation to barrier stabilization. Notably, Se-NPs restored dopaminergic gene expression, modulated inflammatory signaling pathways, and normalized gut-associated microbial markers, thereby supporting nano-mediated regulation of the gut-brain axis. Collectively, this study establishes biogenic Se-NPs as a multifunctional nanotherapeutic that integrates antioxidant signaling, neurovascular protection, and gut-brain axis modulation to counteract rotenone-induced neurodegeneration, highlighting their potential as a nano-enabled strategy for PD intervention.\n\nID: 42454797\nTitle: Electroacupuncture alleviates Parkinson's disease-related pain by inhibiting microglial NLRP3-ASC inflammasome in the amygdala.\nAbstract: This study aimed to investigate the role of microglia and NOD-like receptor protein 3 (NLRP3) inflammasome-mediated neuroimmune pathways in the analgesic effects of electroacupuncture (EA) in a mouse model of Parkinson's disease (PD). Male C57BL/6 mice (8 weeks old) were randomly assigned to the control, PD model, and PD + EA groups. PD was induced by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), while control mice received saline. EA was administered to the motor cortex once daily for five consecutive days in the PD + EA group, whereas PD model mice were restrained without receiving EA stimulation. Behavioral assessments were performed to evaluate motor function and nociceptive sensitivity. Immunohistochemistry, immunofluorescence, and western blot analyses were used to quantify tyrosine hydroxylase (TH), ionized calcium-binding adapter molecule 1 (Iba-1), NLRP3 inflammasome components, and inflammatory cytokines in key brain regions. Compared with control mice, PD model mice showed reduced motor performance and heightened nociceptive sensitivity, accompanied by a decrease in TH-positive neurons and an increase in Iba-1-positive microglia in both the substantia nigra and amygdala. EA significantly improved motor performance and increased pain thresholds. Moreover, EA preserved TH-positive neurons, suppressed microglial activation, and downregulated the expression of NLRP3, ASC, caspase-1, interleukin (IL)-1\u03b2, IL-6, and tumor necrosis factor (TNF)-\u03b1 in the amygdala. These findings suggest that EA alleviates PD-related pain, possibly by modulating microglial activation and NLRP3 inflammasome signaling in the amygdala, thereby reducing neuroinflammation.\n\nID: 42452254\nTitle: Comparative Study of Young and Mature Dendropanax morbifera Leaves: Superior Neuroprotective Efficacy of Young Leaves Through Enhanced Anti-Inflammatory and Metabolic Modulation.\nAbstract: Neuroinflammation, driven by microglial activation and oxidative stress, is a key pathological feature of various neurodegenerative diseases. Dendropanax morbifera L\u00e9veille (DM) is a medicinal plant known for its diverse pharmacological activities; however, the influence of leaf developmental stage on its neuroprotective potential remains poorly understood. In this study, we compared the phytochemical profiles of young DM (YDM) and mature DM leaves and evaluated their effects on neuronal metabolism and microglia-mediated neuroinflammation. HPLC analysis revealed that YDM contained approximately 2.4-fold higher levels of chlorogenic acid than DM, while DM exhibited higher quercetin content. In differentiated N2A neuronal cells, YDM treatment significantly upregulated the expression of key metabolic and mitochondrial regulators, including PGC-1\u03b1, PPAR\u03b3, and CPT2, suggesting enhanced mitochondrial and metabolic regulatory signaling related to biogenesis and fatty acid \u03b2-oxidation. Under inflammatory conditions, YDM more potently suppressed the secretion of pro-inflammatory cytokines (IL-6 and TNF-\u03b1) in LPS-stimulated BV2 microglia compared to DM. Furthermore, in N2A cells treated with BV2-conditioned medium, both extracts effectively mitigated reactive oxygen species production and restored brain-derived neurotrophic factor expression. These findings demonstrate that leaf age is a critical determinant of the phytochemical composition and biological activity of DM. Our results suggest that chlorogenic acid-rich YDM preparations may offer superior therapeutic advantages in targeting neuroinflammatory and metabolic dysregulation in the central nervous system.\n\nID: 42450578\nTitle: Mulberroside A Alleviates Scopolamine-Induced Cognitive Deficits by Suppressing Neuroinflammation and Oxidative Stress via the Dubosiella-Associated Microbiota-Gut-Brain Axis.\nAbstract: Mulberroside A (MsA) possesses neuroprotective effects, but whether it alleviates Alzheimer's disease (AD)-like cognitive impairment through the microbiota-gut-brain axis remains unclear. Using a scopolamine-induced mouse model of acute cognitive impairment (male ICR mice, n = 10/group), we demonstrated that daily administration of MsA (10, 20, and 30 mg/kg/day) for 5 weeks significantly ameliorated cognitive performance in novel object recognition and Morris water maze tests. At the optimal dose (30 mg/kg/day), MsA suppressed hippocampal microglial activation, reduced pro-inflammatory cytokines (IL-6, IL-1\u03b2, TNF-\u03b1), and attenuated oxidative stress by decreasing malondialdehyde (MDA) while restoring superoxide dismutase (SOD) and glutathione (GSH) levels. MsA also strengthened intestinal barrier integrity (ZO-1, occludin) and significantly altered the gut microbiota, notably increasing the beneficial genus Dubosiella. Brain metabolomics indicated that MsA reversed scopolamine-induced metabolic disturbances, mainly restoring phospholipid balance. Correlation analysis demonstrated a strong gut-brain connection, with Dubosiella abundance positively associated with neuroprotective phospholipids and negatively with stress markers. Furthermore, fecal microbiota transplantation from MsA-treated donors successfully replicated these behavioral improvements in recipient mice, underscoring the functional involvement of the reshaped microbiome rather than a simple autonomous recovery. These results suggest that MsA alleviates AD-like cognitive impairment by reducing neuroinflammation and oxidative stress through microbiota remodeling, enhancing the intestinal barrier, and modulating the Dubosiella-associated gut-metabolite-brain axis, making MsA a promising multi-target nutraceutical for ameliorating AD-like cognitive deficits.\n\nID: 42450024\nTitle: Fenfluramine Attenuates Retinal Microglial Activation but Does Not Rescue Structural and Vascular Deficits in a Rat Model of Dravet Syndrome.\nAbstract: Dravet syndrome (DS) is a severe developmental and epileptic encephalopathy caused by SCN1A haploinsufficiency. While brain pathology has been extensively studied, the retina remains underexplored. This study investigated retinal structural, functional, vascular, and cellular changes in a Scn1a+/- rat model of DS. Anatomical quantification revealed thinning of the retinal nerve fiber layer and thickening of the outer plexiform layer. Electroretinography (ERG) showed selectively reduced oscillatory potential amplitudes, suggesting dysfunction of neurovascular coupling. Consistent with these findings, immunohistochemistry demonstrated aberrant vascular morphology, including increased vessel curvature and reduced branching density. In addition, we observed robust microglial activation in the outer and inner plexiform layers; however, astrocyte morphology remained largely unchanged. Fenfluramine, an approved anti-seizure drug for DS, attenuated microglial activation but failed to rescue retinal structural or vascular deficits, indicating a dissociation between its anti-inflammatory and disease-modifying effects. Our findings suggest that multimodal retinal assessment could serve as a noninvasive biomarker platform for monitoring disease progression and therapeutic response in DS.\n\nID: 42492072\nTitle: Examining Mgat5 upregulation's protective effects and underlying mechanisms in spinal cord injury.\nAbstract: Secondary inflammation severely hinders recovery after spinal cord injury (SCI). This study investigates whether boosting Mgat5-mediated N-glycosylation via a lentiviral vector can reprogram the local immune microenvironment and foster functional repair. We engineered a lentiviral vector to overexpress Mgat5 (Lv-Mgat5) and validated it in rat dorsal root ganglion cells. Next, we established a contusion SCI model in rats, dividing them into sham, SCI, MP (methylprednisolone), Lv-vector, and Lv-Mgat5 groups. Motor recovery was evaluated using BBB and inclined plane tests. To uncover the mechanisms, we quantified N-glycan branching (PHA-L precipitation), inflammatory cytokines (ELISA), and regeneration markers (Western blot). Lv-Mgat5 effectively upregulated \u03b2-1,6-GlcNAc branching both in vitro and in vivo without cytotoxicity. Importantly, this targeted intervention modulated the injured spinal cord microenvironment toward an anti-inflammatory profile. We observed a significant drop in TNF-\u03b1 and IL-1\u03b2, alongside a surge in IL-10 (p\u2009<\u20090.05). Furthermore, GAP-43 expression remained robustly elevated. Consequently, rats treated with Lv-Mgat5 showed remarkable and sustained improvements in hindlimb motor function compared to vehicle controls (p\u2009<\u20090.01). Targeted Mgat5 upregulation effectively modulates the post-injury microenvironment. By reshaping the N-glycosylation profile, it attenuates secondary neuroinflammation and supports a regeneration-associated molecular response, offering a promising target for gene therapy after SCI.\n\nID: 42491970\nTitle: Discovery of novel indazole derivatives with anti-neuroinflammatory activity.\nAbstract: This study focuses on the critical role of microglia-mediated neuroinflammation in various neurological disorders. Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.\n\nID: 42491620\nTitle: The role of ucOCN in aerobic exercise induced amelioration of autism spectrum disorder phenotypes.\nAbstract: Autism spectrum disorder (ASD) is a severe neurodevelopmental disorder closely associated with synaptic dysfunction that contributes to core behavioral deficits. Aerobic exercise (AE) serves as a promising adjuvant intervention for diverse neuropsychiatric conditions, and accumulating evidence suggests favorable effects of AE on ASD-related behaviors and physiological traits. The bone-derived hormone undercarboxylated osteocalcin (ucOCN) induced by AE can cross the blood-brain barrier to regulate synaptic plasticity. Mendelian randomization analysis suggests an association between genetically predicted higher physical activity levels and lower ASD risk, as well as between physical inactivity and higher ASD risk. In BTBR mice (a classic ASD animal model), AE intervention was associated with improvements in ASD-like phenotypes, increased cortical ucOCN, GPR158, BDNF, and synaptic proteins, and altered MAPK/ERK/Akt2 signaling. This work provides potential mechanistic clues for AE-associated changes in synaptic plasticity, supporting non-pharmacological intervention strategies for ASD.\n\nID: 42491578\nTitle: Peripheral inflammation impairs glymphatic function, contributing to neurodegeneration in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is associated with systemic immune alterations and glymphatic dysfunction, both of which are linked to brain structural and network changes that contribute to cognitive decline. In 570 participants with AD, mild cognitive impairment, or normal cognition, we combined peripheral immune profiling with multimodal magnetic resonance imaging (MRI) to evaluate glymphatic function, brain structure, and network organization. AD was characterized by reduced analysis along the perivascular space index, enlarged choroid plexus (CP) volume, increased white matter free water, reduced lymphocyte count, and elevated neutrophil-to-lymphocyte ratio (NLR). Immune indices, including NLR, platelet-to-lymphocyte ratio, systemic immune-inflammation index, and lymphocyte count, were associated with cognition and glymphatic-related MRI measures. Mediation analyses indicated that NLR influenced cognition indirectly through CP volume and downstream brain structural and network features. These findings link peripheral immune imbalance to cognitive decline through glymphatic and brain network alterations, supporting biomarker development and mechanism-guided therapeutic strategies.\n\nID: 42491221\nTitle: Acupuncture-induced HSP70 upregulation in neuroprotection: mitochondrial and anti-apoptotic mechanisms.\nAbstract: Heat shock protein 70 (HSP70) represents a major stress-inducible chaperone, holding considerable significance in regulating the proteostasis, mitochondrial homeostasis, and apoptosis in the injured nervous system. Acupuncture has shown neuroprotective effects in multiple models of neurological diseases, yet the role of HSP70 as a mechanistic link between acupuncture stimulation and neuronal protection has not been systematically clarified. To this end, current evidence on acupuncture-induced HSP70 regulation is hereby summarized, and its potential contribution to neuroprotection is accordingly discussed, with particular emphasis on mitochondrial preservation and anti-apoptotic signaling. Available studies suggest that acupuncture-associated HSP70 upregulation is linked to enhanced cellular stress adaptation, reduced oxidative injury, stabilization of Bcl-2 family-dependent mitochondrial integrity, inhibition of cytochrome c release and apoptosome formation, and suppression of downstream caspase activation. In addition to these intracellular effects, emerging evidence also uncovers the involvement of HSP70 in neuroinflammatory regulation and neuron-glia communication, suggesting its broader role in shaping the injured neural microenvironment. However, current evidence remains largely associative, leaving several key issues unresolved, including questions of causal necessity, cell-specific regulation, intercellular trafficking, and neuroimmune integration. Overall, HSP70 may represent a promising integrative mediator of acupuncture-induced neuroprotection, yet its precise mechanistic function still warrants further experimental validation.\n\nID: 42491134\nTitle: Epitranscriptomic regulation by m6A in immunity and autoimmune disorders: emerging mechanisms and clinical perspectives.\nAbstract: Immune-mediated diseases arise from intricate interactions among genetic, environmental, and epigenetic factors that disrupt immune homeostasis. In recent years, epigenetic mechanisms have been widely explored as critical factors in autoreactivity. Among these modifications, N6-methyladenosine (m6A) RNA methylation stands out as a pivotal post-transcriptional regulator of immune cell function and autoimmune diseases (ADs) progression. This review outlines m6A regulation in immune microenvironments and its dual role in maintaining tolerance and promoting inflammation. This study highlights how m6A regulators, including writers (METTL3/14), erasers (FTO and ALKBH5), and readers (YTHDF1-3 and IGF2BP3), orchestrate immune cell dysfunction across systemic (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis) and organ-specific (multiple sclerosis (MS), inflammatory bowel disease (IBD), type 1 diabetes mellitus (T1DM), and autoimmune thyroid disease (AITD) ADs, revealing disease-specific epitranscriptomic regulatory patterns. Critically, we highlight recent therapeutic breakthroughs targeting m6A regulators, including METTL3 inhibition (STM2457) for Th17-driven MS and RA synovitis, ALKBH5 modulation (ALK-04) to mitigate psoriasis flares and neuroinflammation, FTO-targeting small molecules (Rhein) to prevent RA-associated bone erosion, and IGF2BP3 blockade (triptolide) to suppress RA fibroblast activity. Despite their promise, key challenges persist, including stage-specific effects (early vs. chronic), rare immune subset targeting (MDSCs in AIH), and concerns about the long-term safety of epitranscriptomic drugs. Future studies must address m6A dynamics in immune crosstalk to advance precision medicine strategies, particularly through combinatorial approaches with existing JAK inhibitors or checkpoint modulators.\n\nID: 42490999\nTitle: Alteration of glucose neurometabolism and brain morphology in mild behavioral impairment: a neuroimaging study on cognitively healthy individuals.\nAbstract: Regional brain enlargement and increased glucose neurometabolism do not normally indicate neurodegeneration. Mild behavioral impairment (MBI) occurring in cognitively healthy individuals, however, might be significantly affected by these processes. Three hundred forty-one cognitively normal individuals were analyzed using partial least squares (PLS) regression to determine neurometabolic and brain volumetric determinants of MBI scores. Radiolabeled glucose non-displaceable binding potential and volumes of Schaefer homooxygenation parcels were screened as regressors. PLS models were evaluated with cross-validation, scrambling, and bootstrapping. Hypermetabolism in the left entorhinal cortex and hypertrophy in the left dorsal attention network B contribute substantially to the MBI total score. Significant morpho-functional interactions were observed between the right middle temporal cortex and the right salience-ventral attention B network. MBI might depend on cerebral bioenergetic processes and morpho-functional interactions. Relative hypermetabolism and hypertrophy could be considered specific biomarkers of MBI indicating a prodromal maladaptive neural response.\n\nID: 42490925\nTitle: Sensory signaling mediates the systemic metabolic and neurological effects of epigallocatechin gallate.\nAbstract: Epigallocatechin gallate (EGCG), the primary green tea flavanol, is renowned for its diverse health benefits; however, its low systemic bioavailability presents a long-standing paradox in nutritional science. We hypothesized that EGCG exerts its physiological effects via oral chemosensory signaling pathways, independent of intestinal absorption. This study utilized wild-type and Skn-1a-/- mice (lacking bitter taste signaling) to evaluate acute metabolic responses. Furthermore, a chronic study using high-fat/high-sucrose diet (HFSD)-fed rats was conducted to investigate the long-term effects of EGCG on systemic metabolism, neuroinflammation, and adipose and skeletal muscle morphology. Acute oral administration of EGCG or the bitter tastant denatonium benzoate significantly attenuated glycemic excursions and elevated plasma glucagon-like peptide-1 (GLP-1) levels in wild-type mice. Crucially, these effects were completely abolished in Skn-1a-/- mice, identifying bitter taste receptors as essential mediators. In the chronic rat model, repeated oral EGCG treatment effectively reduced food intake, body weight gain, and adiposity. Beyond metabolic regulation, EGCG suppressed Iba-1 expression in the hippocampal dentate gyrus, indicating an anti-neuroinflammatory effect. Notably, EGCG increased the cross-sectional area of both the soleus and extensor digitorum longus muscles across all diet groups, mimicking the beneficial effects of physical exercise. These findings indicate that EGCG acts as a \"metabolic trigger\" through Skn-1a-dependent chemosensory pathways, primarily involving T2R signaling. By demonstrating that bitter-related chemosensory signaling regulates systemic homeostasis and provides neuroprotective effects, this study supports a new concept of \"sensory nutrition.\" This research positions gastrointestinal and oral chemosensors as a novel and non-invasive therapeutic target for managing metabolic syndrome and cognitive decline, overcoming the limitations of systemic bioavailability.\n\nID: 42490858\nTitle: Microbial metabolites at the nexus of gut-brain communication and neurodevelopmental disorders.\nAbstract: The microbiota-gut-brain axis (MGBA) has emerged as a critical regulator of neurodevelopment, with microbial metabolites serving as key signaling molecules that bridge the intestinal ecosystem and the central nervous system. This review gathers current evidence that connects disruptions in microbial metabolites to the pathogenesis of neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Our comprehensive overview discusses major neuroactive metabolite classes-short-chain fatty acids (SCFAs), tryptophan derivatives, bile acids, and phenolic compounds-and their established roles functions in affecting neuroinflammation, epigenetic programming, synaptic function, and blood-brain barrier integrity. Converging evidence from human multi-omics studies and preclinical models frequently reported patterns of metabolic dysregulation in NDDs, including reduced SCFA production, altered kynurenine pathway metabolites, and accumulation of neurotoxic compounds such as para-cresol (p-cresol). However, substantial heterogeneity exists across studies, and causal evidence in humans remains predominantly associative. We further examine the critical early-life window during which the metabolite-producing microbiome is shaped by maternal factors, nutrition, and environmental exposures, with lasting consequences for neurodevelopmental trajectories. Finally, we discuss new intervention strategies such as probiotics, dietary substrates, fecal microbiota transplantation, and metabolite-based therapies, and propose a plan to transition from associative findings to causal, personalized approaches using microbial metabolites as biomarkers and therapeutic targets in child neurodevelopment.\n\nID: 42490834\nTitle: Rather a versatile multi-tool than a sword: an integral role of the plasminogen system in health and disease.\nAbstract: Proteolysis, the irreversible, hydrolytic cleavage of peptide bonds by proteases, is essential for life. The plasminogen system, one of the central proteolytic systems, regulates diverse physiological pathways, including fibrinolysis, inflammation, wound healing, and tissue remodelling. Beyond its proteolytic functions, the plasminogen system serves as a hub for crosstalk to maintain homeostasis. Yet, its dysregulation, misuse, or hijacking by pathogens can drive pathologies such as hereditary disorders, tumour dissemination, bacterial invasion, and viral priming. This review explores its evolution, structural aspects, activation mechanisms, regulatory pathways, and pharmacological modulation of the plasminogen system, synthesising decades of research with recent advances. We highlight the multifaceted nature of the plasminogen system-as both a guardian of physiological balance and a potential driver of disease-and discuss its components as therapeutic targets and tools.\n\nID: 42490679\nTitle: Platelet membrane biomimetic nanoparticle-based targeted delivery system of simvastatin for the treatment of ischemic stroke.\nAbstract: Blood-brain barrier (BBB) disruption and excessive neuroinflammation are pivotal drivers of cerebral ischemia-reperfusion injury. Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke.\n\nID: 42490473\nTitle: Single-cell multiomics connects 3D genome and transcriptome alterations in Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) disrupts brain function through cell type-specific transcriptomic and epigenomic alterations, yet the contribution of three-dimensional (3D) genome organization to AD remains poorly understood. We applied GAGE-seq (genome architecture and gene expression by sequencing) to jointly profile gene expression and 3D chromatin structure in single cells from postmortem brain tissue from AD patients and age-matched individuals without AD, revealing chromatin reorganization linked to cell type-specific dysregulation. Integrations with spatial transcriptomics and chromatin accessibility data uncovered altered niches reflecting genome compartment remodeling and regulatory element reorganization. Hicformer, a deep learning framework, showed that 3D genome features are essential for predicting disease-relevant, cell type-specific gene expression changes. Our results establish higher-order chromatin alterations as a component of AD-associated molecular pathology, providing a multiscale view of transcriptional regulation and 3D genome organization in neurodegeneration.\n\nID: 42490372\nTitle: Conformational diversity and interaction signatures of NADH across protein families.\nAbstract: Nicotinamide adenine dinucleotide (NADH) is a ubiquitous redox cofactor that participates in a wide range of enzymatic and regulatory processes. These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors.\n\nID: 42490157\nTitle: Characterizing enteric pathology in MPS IIIA mice suggests disease-specific vulnerability among lysosomal storage disorders.\nAbstract: \n\nID: 42490144\nTitle: Progressive hypothalamic neuroinflammation in ovariectomized mice parallels aging-related transcriptomic changes in the female human hypothalamus.\nAbstract: The hypothalamic changes that occur after the loss of ovarian estrogen remain poorly characterized. Here, we performed a comprehensive temporal characterization of the mouse hypothalamus following ovariectomy (OVX), combining physiological measurements with bulk RNA-sequencing of the posterior hypothalamus (PH) and preoptic area (POA) at short-term (14 days) and long-term (4 months) post-OVX. Serum LH levels rose progressively and then declined, while core temperature peaked early and subsequently normalized, recapitulating the endocrine and thermoregulatory dynamics of reproductive aging in humans. Transcriptomic analysis revealed time-dependent activation of inflammatory pathways, glial markers, and KNDy neuron-related gene networks, with the most pronounced changes emerging at 4 months post-OVX, particularly in the PH. Immunofluorescence confirmed increased NKB release, declining KNDy neuronal activity, and heightened astrocytic reactivity in the arcuate nucleus after prolonged estrogen withdrawal. To contextualize these findings, we analyzed publicly available human hypothalamic RNA-seq data across chronological age. Age-related transcriptomic patterns in women, including progressive inflammatory signaling, glial activation, and altered KNDy gene expression, showed significant correlation with the OVX mouse model, particularly at the pathway level. These findings establish a temporal framework for hypothalamic molecular changes after estrogen withdrawal, identify conserved neuroinflammatory signatures across species, and provide a preclinical platform for testing interventions targeting menopausal-associated hypothalamic dysfunction.\n\nID: 42489993\nTitle: Multimodal microscopic and spectroscopic characterisation of heterogeneous iron oxyhydroxides in the human globus pallidus.\nAbstract: Iron is essential for neuronal metabolism, neurotransmitter synthesis, and enzymatic function; however, dysregulated accumulation contributes to oxidative stress and neurodegeneration. The basal ganglia, particularly the globus pallidus, represent a hotspot for iron deposition, yet the precise structural forms and their implications remain incompletely understood. Here, a multimodal approach was applied combining Raman microspectroscopy, light microscopy, transmission (TEM) and scanning electron microscopy coupled with energy-dispersive X-ray analysis (SEM-EDX) to characterise iron-rich deposits in post-mortem human globus pallidus. Tissue samples from six individuals without neurological disease were examined. Perls' staining revealed iron-positive, spherical inclusions 10-20\u00a0\u00b5m in diameter. Raman spectroscopy revealed bands at 268-278, 490, 526, and 603\u00a0cm-1, as well as broader signals at 1259-1349\u00a0cm-1, consistent with magnetite, maghemite, hematite, and ferritin-like structures. Additional vibrations in the 682-1532\u00a0cm-1 range indicated interactions with organic matrices, such as protein or lipid components. SEM-EDX identified both regular and irregular iron-rich particles with multielemental composition, including C, O, Al, Si, P, S, Ca, Cr, and Ni, in addition to Fe. TEM examination showed the micrometre-sized particles of hematite and aggregation of ferrihydrite. These findings suggest that iron deposits in the globus pallidus comprise heterogeneous mixtures of oxides and hydroxides with variable crystallinity. Depending on their crystallinity and surface reactivity, such phases may represent a potential pool of redox-active iron; however, the present study did not assess markers of oxidative stress, and their physiological versus pathological significance remains to be established.\n\nID: 42489969\nTitle: NAD\u207a biology and supplementation: From mechanisms to clinical perspectives.\nAbstract: This study examines the biological and clinical relevance of NAD\u207a supplementation using a combined review and mathematical modelling approach. NAD\u207a plays a central role in cellular energy metabolism, redox balance, and signaling pathways linked to aging, neurodegeneration, and metabolic health. Current evidence shows that oral NAD\u207a precursors such as nicotinamide riboside and nicotinamide mononucleotide can increase circulating NAD\u207a levels, although their clinical benefits remain variable and context-dependent. Intravenous NAD\u207a administration is less well characterized and lacks robust clinical validation. The modelling framework presented here highlights that NAD\u207a responses are nonlinear and influenced by factors such as dose, age, metabolic state, and route of administration. Rather than following a simple dose-response relationship, NAD\u207a supplementation appears to operate within a complex regulatory system involving feedback mechanisms and biological saturation. Overall, these findings emphasize the need for cautious interpretation of current data and for well-designed clinical studies to define effective and safe therapeutic strategies.\n\nID: 42489942\nTitle: From synaptic development to degeneration: a narrative review of small molecule strategies targeting alpha-synuclein in Parkinson's disease.\nAbstract: Aggregation of \u03b1-synuclein (\u03b1-Syn) is a defining pathological feature of Parkinson's disease (PD), contributing to progressive neuronal dysfunction and death. Unlike prior reviews focused predominantly on aggregation as an isolated endpoint, this review proposes a neurodevelopmental-neurodegenerative continuum as an interpretive framework, suggesting that \u03b1-Syn's physiological roles in synaptic development and circuit maturation may be linked to its later pathological behaviour. Within this context, we discuss recent advances in small-molecule strategies targeting key stages of \u03b1-Syn pathology, including synthesis, misfolding, aggregation, post-translational modification, and clearance. These include translation and misfolding inhibitors, aggregation modulators such as minzasolmin (UCB0599), epigallocatechin gallate and anle138b, as well as compounds that enhance \u03b1-Syn degradation through autophagy-lysosomal and ubiquitin-proteasome pathways. Additional strategies targeting proteostasis and mitochondrial dysfunction are also considered. Beyond its pathogenic role, \u03b1-Syn contributes to synaptic vesicle trafficking, neurotransmitter release, and neuronal maturation, and disruption of these functions may increase vulnerability to later neurodegeneration. In conclusion, small-molecule-based therapies represent a promising multi-targeted strategy for PD; however, key translational challenges and unresolved questions remain, including optimisation of pharmacokinetics, target specificity, and blood-brain barrier (BBB) penetration and validation in clinical settings.\n\nID: 42489872\nTitle: Mesenchymal Stem Cell-Based Therapy for Cerebellar Ataxia: From Bench to Bedside.\nAbstract: Cerebellar ataxia (CA) encompasses hereditary and acquired disorders unified by Purkinje cell loss and neuroinflammation, for which no disease-modifying therapy exists. Human mesenchymal stem cells (hMSCs) offer multimodal neuroprotection through paracrine secretion of neurotrophic factors and immunomodulatory mediators. We reviewed preclinical and clinical evidence for hMSC therapy across multiple CA etiologies, integrating findings from neuroinflammatory, toxic/developmental, and genetic mouse models alongside published clinical trials and case reports. A systematic literature search was conducted in PubMed/MEDLINE, Embase, and the Cochrane Library (search period: 2000-2026) using the following key terms: \"mesenchymal stem cell\" AND \"cerebellar ataxia\"; \"MSC\" AND \"spinocerebellar ataxia\"; \"hMSC\" AND \"Purkinje cell\"; \"stem cell therapy\" AND \"ataxia\". Inclusion criteria encompassed: peer-reviewed original research articles and reviews in English; in\u00a0vivo animal model studies; clinical trials, case series, and case reports. Studies addressing non-CA neurological conditions without CA-relevant data were excluded. hMSC transplantation consistently improved motor function, preserved Purkinje cell integrity, and attenuated neuroinflammation across LPS-induced, Ara-C-induced, and SCA2 transgenic models. A critical observation is that MSCs from CA patients exhibit markedly reduced anti-inflammatory secretome capacity compared with healthy-donor MSCs, justifying an allogeneic strategy. Therapeutic efficacy was maintained even after symptom onset in the SCA2 model. A published case report demonstrated safety and preliminary functional benefit of intrathecal allogeneic bone marrow-derived MSCs in a sporadic adult-onset ataxia patient. hMSC therapy targets convergent CA pathomechanisms-microglial suppression, neurotrophin restoration, and Purkinje cell preservation-through a paracrine rather than cell-replacement mechanism. Post-symptomatic efficacy and an emerging clinical evidence base support advancing toward placebo-controlled randomized trials.\n\nID: 42489789\nTitle: Therapeutic and research frontiers in fibromyalgia: integrating pathophysiology with innovative drug repurposing.\nAbstract: Fibromyalgia (FM) is a complex chronic pain syndrome characterized by widespread musculoskeletal pain, fatigue, sleep disturbance, psychological symptoms, and cognitive dysfunction, profoundly impairing quality of life. Despite its multifactorial nature, only a few pharmacological therapies have been approved by the Food and Drug Administration (FDA), and these mainly provide symptomatic relief. Many patients experience inadequate efficacy or intolerable adverse effects, emphasizing the need for further research and improved therapeutic strategies. This review highlights contributing factors in the pathophysiology of FM, including neurochemical alterations, central sensitization, neuroinflammation, oxidative stress, mitochondrial dysfunction, gut microbiota disturbances, and autoimmunity. While some of these factors are well-established, others remain under investigation. Therapeutic strategies are discussed alongside repurposed drugs in preclinical and clinical studies, including N-methyl-D-aspartate (NMDA) receptor antagonists, neurokinin-1 receptor antagonists, drugs targeting the gamma-aminobutyric acid (GABA) system, antiepileptics, antidepressants, opioids, cannabinoids, dopamine receptor agonists, melatonin receptor agonists, and antidiabetics. Future research frontiers in FM should focus on addressing comorbidities and targeting central sensitization by enhancing descending inhibitory pain pathways, suppressing neuroinflammation through NOD-like receptor protein 3 (NLRP3) inflammasome inhibition and promotion of anti-inflammatory glial polarization besides attenuating oxidative stress and mitochondrial dysfunction. Moreover, repurposing drugs from related pain conditions such as migraine and neuropathic pain offers new therapeutic opportunities. Accordingly, this multi-target strategy may facilitate the development of effective therapies for FM.\n\nID: 42489692\nTitle: Curcumin ameliorates Salmonella-induced enteritis by restraining NF-\u03baB signaling and restoring microbiota-SCFA homeostasis.\nAbstract: Foodborne Salmonella infection triggers excessive inflammation, mucosal injury and gut microbiota dysbiosis. Here, curcumin was evaluated as a dietary bioactive against Salmonella-induced enteritis using in silico target-network analysis, macrophage assays and a mouse infection model. Target-network analysis identified 79 shared targets associated with curcumin and intestinal inflammation. In vitro, macrophages were treated with curcumin at 40 and 80 \u03bcM before stimulation with lipopolysaccharide or Salmonella Enteritidis infection. In vivo, mice were challenged with S. Enteritidis and orally gavaged with curcumin at 100 or 200 mg per kg body weight. Curcumin inhibited LPS- and Salmonella-induced NF-\u03baB activation in J774-Dual/RAW264.7 macrophages, decreased IL-1\u03b2, IL-6 and TNF-\u03b1, increased IL-10, and reduced lactate dehydrogenase release by over 35%. In infected mice, curcumin alleviated clinical deterioration (weight loss and hemolysis), attenuated liver and spleen injury, lowered tissue bacterial burden by nearly 2log10 CFU per 100 mg, and improved intestinal histopathology. Notably, 16S rDNA profiling showed that curcumin reversed Salmonella-driven dysbiosis by improving microbial diversity, limiting Proteobacteria/Enterobacteriaceae expansion, and enriching beneficial taxa including Lactobacillus. These compositional shifts were accompanied by recovery of key short-chain fatty acids by 40%-75% (acetate, propionate, butyrate and valerate), indicating restoration of microbiota-linked metabolic homeostasis. Collectively, curcumin mitigates pathogen-associated intestinal inflammation while rebuilding the microbiota-SCFA homeostasis supportive of mucosal barrier function, supporting its development as a food-derived functional ingredient.\n\nID: 42489669\nTitle: The missing link: Piccolino is essential for tethering synaptic vesicles to rod photoreceptor ribbons.\nAbstract: Retinal photoreceptors transmit light signals to their postsynaptic neurons with high precision, speed and without fatigue. This high-throughput neurotransmission relies on a sophisticated molecular machinery centered on a presynaptic organelle, the synaptic ribbon (SR). A hallmark of SRs is the recruitment of synaptic vesicles (SVs) from the cytoplasmic SV pool via \"tethering\". However, the identity of the tether and the mechanism underlying SV tethering are unknown. Here, we show that cell-specific deletion of the SR-associated protein Piccolino from rod photoreceptors disrupts SR morphology and ablates SV tethering. Nanoscale epitope mapping suggests that Piccolino acts as an SV tether by extending its N terminus away from the SR into the SV-filled terminal cytoplasm. With in silico modeling and protein lipid-binding assays, we demonstrate that an amphipathic liquid packing sensor motif (ALPS) at the N terminus of Piccolino binds SV-like liposomes, implicating this interaction as the mechanism underlying SV tethering. Together, our findings identified Piccolino as the molecular link between the SR and SVs.\n\nID: 42489599\nTitle: Molecular Inflammatory Characteristics of Patients With Chronic Pain Under Burst Spinal Cord Stimulation: An Exploratory Study.\nAbstract: Spinal cord stimulation (SCS) has been reported to reduce chronic back and leg pain and improve functional capacity. However, its mechanism of action is not completely understood. One proposed mechanism involves the modulation of central and peripheral inflammatory circuits. This exploratory study enrolled 28 participants (11 healthy controls [HC] and 17 patients with chronic back and/or leg pain of various origin). Pain intensity (Numeric Rating Scale), sleep quality (Pittsburgh Sleep Quality Index), mood (Beck Depression Inventory), disability (Oswestry Disability Index), and levels of pro- and anti-inflammatory cytokines (adiponectin, ghrelin, interleukin [IL]-10, high-mobility group box 1-protein, tumor necrosis factor alpha, IL-6, IL-1\u03b2, leptin) were collected at baseline and after three months of burst SCS and compared with HC. A total of 11 men and six women (mean age 68.4 \u00b1 11.2 years) underwent permanent SCS implantation. Pain intensity significantly decreased at follow-up (p < 0.001), accompanied by improvements in sleep quality (p = 0.002), mood (p = 0.001), and disability (p < 0.001). At baseline, proinflammatory tumor necrosis factor alpha levels were significantly elevated (p = 0.006), whereas anti-inflammatory IL-10 levels were significantly reduced compared with HC (p = 0.004). At follow-up, IL-10 levels increased, attenuating the difference between patients and HC such that no statistical significance was observed. Levels of pro- and anti-inflammatory cytokines showed no significant correlations with clinical outcome measures. Consistent with previously published data, we found a proinflammatory profile in patients with chronic pain at baseline. After three months of burst SCS anti-inflammatory IL-10 was increased along with improved pain and functional capacity. However, a causal relationship between burst SCS and neuroinflammatory mediators in chronic back and/or leg pain could not be established.\n\nID: 42489531\nTitle: Biochemical modulators of synaptic plasticity: New horizons in Alzheimer's disease treatment.\nAbstract: Synaptic dysfunction is the earliest and most critical pathological feature of Alzheimer's disease (AD), directly contributing to cognitive decline. This review provides an integrative overview of the molecular and biochemical modulators governing synaptic plasticity and their disruption in AD. We discuss how the collective impairment of A\u03b2 aggregation, tau pathology, calcium imbalance, oxidative stress, and neuroinflammation affects dendritic spine morphology and synaptic connectivity. Particular attention is given to neurotrophins such as brain-derived neurotrophic factor and TrkB signaling, hormonal influences, likewise glucocorticoids, estrogens, testosterone, endocannabinoid pathways, lipid and cholesterol regulators like ApoE and lipid rafts, and epigenetic mechanisms that modulate synaptic resilience. We further evaluate the therapeutic potential of pharmacological agents, including cholinesterase inhibitors, NMDA receptor modulators, and multi-target directed ligands alongside nutraceuticals such as resveratrol, curcumin, omega-3 fatty acids, Withania somnifera, and Bacopa monnieri. Emerging technologies, including iPSC-derived neuronal models, optogenetics, and advanced neuroimaging biomarkers like SV2A PET, cerebrospinal fluid/plasma neurogranin, are also highlighted for their role in elucidating and monitoring synaptic integrity. Ultimately, targeting the biochemical modulators of synaptic plasticity offers a promising avenue for AD therapy, especially through combinatorial and precision-medicine strategies aimed at restoring synaptic function and cognitive performance.\n\nID: 42489523\nTitle: Reduced differentiation of personality in Alzheimer's disease-like dementia and associations between informant report of personality change and cognitive decline.\nAbstract: BackgroundPersonality changes are documented in Alzheimer's disease (AD), but research has focused almost exclusively on how much traits change rather than how the underlying personality structure reorganizes. Recent evidence from healthy aging shows that personality traits can de-differentiate over time, suggesting a decline of coherence of traits with age. Whether such personality de-differentiation also occurs in neurodegeneration and how personality and cognitive changes relate remains unknown.ObjectiveThis study aimed to examine structural changes in personality traits in individuals with AD-like dementias, using the HEXACO personality model administered cross-sectionally to informants and to a control group of informants of healthy older adults, and explore dimensional changes in the relationship between reported changes in personality and cognition.Methods207 informants of persons with AD-like dementia and 201 informants of healthy older adults completed the Hexaco Adjective Scales, referring both to the present time and to perceived changes in personality, and a questionnaire (e-Cog) to assess cognitive changes.ResultsPrincipal component analysis revealed a simplified personality structure in persons with AD but not in healthy older adults, with Emotionality not emerging as an independent factor in persons with AD. Network analyses indicated significant links between personality trait changes and declines across cognitive domains that differed between the two groups.ConclusionsAD-like dementias are characterized by a reduced differentiation of personality structure paralleling the simplification of cognitive organization, with the strongest impact observed in the Emotionality domain. Personality changes also co-occur with perceived cognitive decline, underscoring the need to integrate personality assessment in evaluating dementia.\n\nID: 42489438\nTitle: APOE4-specific glymphatic effects on clinical progression in the Alzheimer's Disease Neuroimaging Initiative with pathological correlates in the A4 study.\nAbstract: BackgroundThe APOE \u03b54 allele is the strongest genetic risk factor for late-onset Alzheimer's disease (AD). However, some carriers show \"clinical resilience\", maintaining their cognition despite high risk.ObjectiveWe hypothesized that the glymphatic system, the brain's waste clearance pathway, may attenuate APOE \u03b54-mediated neurodegeneration, and tested this in two independent cohorts.MethodsWe analyzed 625 cognitively normal older adults from the Alzheimer's Disease Neuroimaging Initiative (ADNI) discovery cohort and 447 amyloid-positive participants from the preclinical Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) validation cohort. Glymphatic function was estimated using the analysis of diffusional kurtosis imaging along the perivascular space (DTI-ALPS) index in ADNI and choroid plexus (CP) 18F-Flortaucipir PET uptake in the A4 study. Primary outcomes were clinical conversion to dementia (ADNI) and hippocampal tau pathology (A4).ResultsIn the discovery cohort, we observed a trend toward ALPS \u00d7 APOE4 interaction (p\u2009=\u20090.057, not reaching conventional statistical significance). Carriers with preserved function (high ALPS) showed a reduced conversion risk (hazard ratio\u2009=\u20090.52, 95% CI: 0.27-0.99) compared to those with low function. In the validation cohort, glymphatic interface dysfunction (higher CP tau) strongly predicted hippocampal tau burden (p\u2009<\u20090.0001). However, the gene-specific interaction was not replicated (p\u2009=\u20090.928); clearance failure predicted pathology regardless of genotype. Exploratory fluid biomarker analyses in ADNI did not reveal significant interactions.ConclusionsThese findings suggest that preserved glymphatic function is associated with clinical resilience in APOE \u03b54 carriers, though the interaction was borderline (p\u2009=\u20090.057) and should be considered hypothesis-generating. The strong pathological associations with clearance integrity highlight a biologically plausible mechanism in AD pathogenesis that warrants further investigation.\n\nID: 42489330\nTitle: CYP3A4-mediated Effects of Cranberry and Pomegranate Juices on Alprazolam Pharmacodynamics.\nAbstract: Alprazolam, a frequently prescribed anxiolytic, is extensively metabolized in the liver mostly by the cytochrome P450 3A4 (CYP3A4) enzyme. Cranberry and pomegranate juices, often suggested for their possible therapeutic effects in kidney stone management, have been identified as strong inhibitors of CYP3A4. This raises considerable concerns about possible drug-food interactions that could modify the pharmacodynamic profile of alprazolam. This study aimed to comprehensively assess the pharmacodynamic interactions between alprazolam and these juices, focusing on their collective impact on behavioral and histological results. Molecular docking studies were conducted utilizing AutoDock Vina to assess the binding affinities of active compounds from cranberry and pomegranate juices to the CYP3A4 enzyme, resulting in binding energies of -9.2 and -9.3 kcal/mol, respectively. In vivo tests were performed on adult male Wistar albino rats, which were divided into five experimental groups: control, alprazolam alone, and alprazolam co-administered with cranberry juice, pomegranate juice, or a combination of both. Pharmacodynamic interactions were evaluated via behavioral analyses using the Elevated Plus Maze, Rotarod, and Y-Maze tests to assess anxiety, motor coordination, and cognitive performance. Furthermore, histological analyses of brain tissues were performed to detect neuronal changes and evaluate the degree of neurodegeneration linked to the treatment. Molecular docking analyses revealed strong binding affinities of anthocyanins from cranberries and ellagic acid from pomegranates to the CYP3A4 enzyme, suggesting their ability to inhibit its activity. Behavioral tests indicated considerable deficits in memory and motor coordination in groups receiving cranberry or pomegranate drinks in conjunction with alprazolam, relative to the alprazolam-only and control groups. Histopathological examination of brain tissues supported these findings, revealing a significant elevation in neuronal degeneration in the coadministration groups compared to controls, indicating a synergistic effect on neurotoxicity. The pharmacodynamic changes observed suggest that the coadministration of cranberry and pomegranate juices with alprazolam alters the drug's effects, likely due to CYP3A4 inhibition by the juices' phytochemicals. These interactions may enhance alprazolam's neuropharmacological effects, resulting in an increased risk of cognitive and motor impairments. These findings underscore the clinical importance of monitoring food-drug interactions, especially in patients using natural products concurrently with CNS-active medications. This study highlights significant pharmacodynamic interactions between alprazolam and cranberry/pomegranate juices, highlighting their potential to influence the drug's therapeutic effectiveness and safety profile. The findings highlight the essential necessity for monitoring when concurrently administering these natural medicines with alprazolam, as their simultaneous usage may result in altered pharmacological effects and increased risk of adverse effects.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42489248\nTitle: Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke-Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling.\nAbstract: Ischemic stroke induces oxidative stress, neuroinflammation, neuronal death, and synaptic dysfunction, leading to persistent motor and cognitive deficits. The human dental pulp stem cell (hDPSC) secretome is a promising cell-free therapeutic candidate containing neurotrophic, antioxidant, and immunomodulatory factors. Here, we investigated its therapeutic effects in a photothrombotic mouse model of ischemic stroke and CoCl2-induced hypoxic BV2 microglial cells. Proteomic profiling identified antioxidant-associated proteins, including SOD2, GSR, and GSTP1, and microglial phenotype-related candidates, including GRN, CSF1, and LRP1. hDPSC secretome treatment reduced stroke-induced infarct volume and attenuated stroke-increased neuronal apoptosis, neuronal ROS accumulation, and NF-\u03baB-associated inflammatory signaling in the cortex and hippocampus. It also shifted microglial marker expression toward an M2-associated profile and improved stroke-impaired hippocampal neurogenesis, vascular remodeling, and synaptic organization. Proteomic analyses further identified coordinated changes in pathways related to oxidative phosphorylation, inflammatory responses, calcium signaling, SNARE-associated vesicular transport, and ROBO-Rho-associated cytoskeletal remodeling. These molecular and cellular changes were associated with improved motor coordination, spatial learning and memory, contextual memory, and anxiety-like behavior. These findings support the hDPSC secretome as a cell-free therapeutic candidate for post-stroke functional recovery linked to redox, inflammatory, neurovascular, and synaptic remodeling.\n\nID: 42489215\nTitle: Prolonged systemic inflammation worsens impairments to astrocyte Ca2+ and functional hyperemia in Alzheimer's disease.\nAbstract: Chronic neuroinflammation in Alzheimer's disease (AD) alters astrocyte physiology and neurovascular unit function. AD patients frequently experience recurrent systemic inflammatory insults from comorbid conditions, which act as\u00a0\"secondary-hits\" believed to worsen cognitive decline. The impact of these secondary insults \u00a0on astrocyte-mediated neurovascular regulation remains unknown. We applied intravital two-photon microscopy to longitudinally investigate astrocytic Ca2 + dynamics and functional hyperemia during sensory stimulation in APP/PS1dE9 mice before and during secondary lipopolysaccharide (LPS)-induced systemic inflammation. AD mice exhibited diminished stimulation-evoked astrocytic Ca2 + activity, while functional hyperemia remained largely preserved. LPS further suppressed astrocytic Ca2 + responses and produced temporally specific vascular alterations, with AD and wild-type mice following divergent inflammatory trajectories. Our findings provide the first in vivo longitudinal characterization of how secondary systemic inflammation disrupts astrocyte-mediated neurovascular regulation. The selective vulnerability of astrocytic Ca2 + signaling relative to vascular output implicates recurrent inflammatory insults as a clinically relevant contributor to neurovascular dysfunction in preclinical AD.\n\nID: 42489128\nTitle: Photobiomodulation of immune crosstalk rescues neuroinflammation in Alzheimer's disease models.\nAbstract: Peripheral immune cell infiltration and crosstalk with brain-resident cells critically drive Alzheimer's disease (AD)-associated neuroinflammation, highlighting its therapeutic potential. Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration.\n\nID: 42488849\nTitle: Modulation of TH17 cell activity by REV-ERB agonists: path toward novel treatments for canine meningoencephalitis of unknown origin.\nAbstract: Meningoencephalitis of unknown origin (MUO) encompasses a heterogeneous group of non-infectious, presumed autoimmune, central nervous system diseases in dogs and remains a major therapeutic challenge in veterinary neurology. Mounting evidence from both experimental and clinical studies has highlighted the pivotal role of T helper 17 (Th17) cells and their proinflammatory cytokines, especially interleukin-17A (IL-17A), in mediating neuroinflammation similar to that seen in experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) models. REV-ERBs are nuclear receptors that act as transcriptional repressors and regulate immune responses, circadian rhythm, and metabolism. Synthetic REV-ERB agonists, such as SR9009, SR9011, and SR12418, have demonstrated selective suppression of Th17 differentiation and function, reduction of disease severity, and improved safety profiles in preclinical autoimmune models. In addition to Th17 differentiation, REV-ERB's role in other components of the immunomodulating system is ever-growing. Preclinical and translational data support the further exploration of REV-ERB agonists as a potential addition to the targeted immunomodulatory therapies for canine MUO. By continuing to investigate REV-ERB compounds as a component of MUO therapy, researchers can assess their potential for improved efficacy and reduce the side effects associated with traditional immunosuppressive regimens. This review integrates mechanistic insights from immunology, circadian biology, and experimental models, and outlines future directions for clinical translation, highlighting the relevance of REV-ERB agonists in advancing veterinary neuroimmunology and in informing comparative approaches to human neuroautoimmune disease.\n\nID: 42488747\nTitle: Pharmacological advances of honokiol: Mechanisms, targets and therapeutic potential (Review).\nAbstract: Honokiol (HKL), a bioactive biphenolic lignan isolated from the bark of Magnolia officinalis, possesses diverse pharmacological properties, including neuroprotective, antitumor, anti-inflammatory and metabolic regulatory effects. Despite its therapeutic promise, the clinical application of HKL is severely restricted by its hydrophobicity and low oral bioavailability. The present review systematically summarized 99 studies (90 original articles and nine reviews) on the pharmacological profile of HKL. It detailed HKL's molecular interactions with key signaling targets, such as sirtuin 3, NOD-like receptor family pyrin domain containing 3-cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes, Yes-associated protein/transcriptional coactivator with PDZ-binding motif, adenosine monophosphate-activated protein kinase and signal transducer and activator of transcription 3, which underly its efficacy against cancer (ovarian, liver, breast, colorectal, and lung), neurodegeneration (Alzheimer's and Parkinson's disease), metabolic disorders (diabetes, nonalcoholic fatty liver disease and obesity) and inflammatory and infectious diseases. Furthermore, the present review critically evaluated recently developed strategies to overcome its pharmacokinetic limitations. The present review offered an updated theoretical basis for understanding the structure-activity relationship of HKL and provided insights into its translation from bench to bedside.\n\nID: 42488725\nTitle: Prenatal and neonatal housing conditions affect anxiety-like behavior in adulthood in rats and interact with brain-derived neurotrophic factor (BDNF) Val66Met to alter expression of BDNF and stress markers in the ventral hippocampus.\nAbstract: We investigated the interaction of the brain-derived neurotrophic factor (BDNF) gene variant, Val66Met, with the effect of prenatal/neonatal environmental conditions on anxiety-like behavior in adulthood in rats. In a genetic Val66Met rat model, we compared the effects of a high-enrichment/high-complexity early-life environment (HE) and a low-enrichment/low-complexity environment (LE). Body weight was higher in both male and female HE rats compared to LE rats. Anxiety-like behavior on a plus maze or in an open field was enhanced in both male and female HE rats compared to LE rats. In contrast, following HE, only in females, adrenal weight was higher, and in the forced swim test, immobility was lower, and swimming was higher. Body weight and behavioral changes did not differ between BDNF genotypes. Fear conditioning and extinction were not affected. The effect of HE vs. LE condition on expression of BDNF, the antioxidant transcription factor, NRF2, and the glucocorticoid receptor, NR3C1, in the ventral hippocampus varied depending on genotype, and most of these changes were again only seen in females. There were no effects on the expression of the stress markers, SGK1 and FKBP5, or the mineralocorticoid receptor, NR3C2. These results show persistent effects of early-life environment on anxiety-like behavior and gene expression of BDNF and stress markers in adulthood, with some effects showing sex- and Val66Met genotype specificity. These results may be important for our understanding of factors involved in the development of clinical anxiety and depression, and also have implications for animal welfare in the laboratory setting.\n\nID: 42488718\nTitle: Gasotransmitters in Glaucoma: A New Paradigm.\nAbstract: Glaucoma, an ocular neurodegenerative condition, is the second leading cause of permanent loss of vision globally. It is characterized by progressive retinal ganglion cell (RCG) loss, optic nerve-head damage, irreversible visual field loss, and sometimes, increase in intraocular pressure (IOP). Existing therapeutic strategies target elevated IOP, the only modifiable risk factor for the disease, and fail to address the co-current neurodegeneration in the posterior segment of the eye. This demonstrates a huge gap in effective glaucoma therapy and highlights the need for multitargeting treatments that simultaneously reduce IOP in the anterior segment and mitigate neurodegeneration in the posterior segment of the eye. There is evidence that gasotransmitters such as nitric oxide (NO) and hydrogen sulfide (H2S) could be beneficial in the treatment of glaucoma due to their ability to reduce IOP and mitigate neurodegeneration in the mammalian eye; while the second gasotransmitter, carbon monoxide (CO) can relax trabecular meshwork, enhance ocular perfusion and mitigate retinal neuronal apoptosis. Since current glaucoma therapies focus on IOP reduction, the multi-targeting nature of these gasotransmitters renders them as viable drug candidates to shift glaucoma therapy from IOP-targeting to multiple targeting therapeutic agents with improved patient outcomes.

Dysregulated SIRT activity has been extensively studied in aging, metabolic syndrome, cardiovascular disease, neurodegeneration, cancer, and immune disorders. However, robust human evidence and SIRT-targeted therapies are lacking. Transgenic mouse models serve as key platforms to study gene function and guide therapeutic development. This review synthesizes evidence from Sirt1-7 transgenic mouse models regarding the core cellular processes governed by SIRTs: metabolism, genome integrity, stress resistance, immunity, and autophagy, and illustrates their operation across different organ systems. By comparing global, tissue-specific, and inducible knockout (KO) and overexpression (OE) models of cardiovascular, respiratory, digestive, nervous, endocrine, urogenital, musculoskeletal, malignant, and immune diseases, we identified central regulatory SIRTs (SIRT1, SIRT3, and SIRT6), context-dependent modifiers (SIRT2, SIRT4, SIRT5, and SIRT7), and their organ- and cell type-specific functions. We also summarize representative small-molecule SIRT activators, inhibitors, and degraders, covering both clinical and preclinical studies, and highlight where contradictions and knowledge gaps remain. Together, these analyses help clarify which aspects of SIRT modulation are most promising and under what isoform, tissue, and disease contexts they should be pursued for the development of SIRT\u2011targeted therapies in human disease.\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=======================================================\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.

The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants.\n --- END ACTUAL ABSTRACT FOR 41935130 ---\n\n- ERROR: You cited ID: 41926238 for the quote: \"2'-FL markedly increased short-chain fatty acids (SCFAs)-producing beneficial bacteria... accompanied by increased fecal acetate and butyrate.\"\n FACT: Ellipses (...) are strictly forbidden.

However, the role of 2'-FL in metabolic hypertension (MH) remains unclear. This study aimed to evaluate the effects of 2'-FL on MH and explore its underlying mechanisms. 2'-FL treatment (1000 mg/kg) reduced systolic blood pressure (SBP) by 16.6% and alleviated dyslipidemia, microglial activation, and neuroinflammation in MH mice. 2'-FL markedly increased short-chain fatty acids (SCFAs)-producing beneficial bacteria, e.g., Akkermansia and Bifidobacterium by 3.9-fold and 19.5-fold, accompanied by increased fecal acetate and butyrate. Notably, the benefits of 2'-FL for MH were transferable via fecal microbiota transplantation (FMT). Particularly, 2'-FL-mediated attenuation of vascular dysfunction was associated with the inhibition of the lipopolysaccharide/toll-like receptor 4 (LPS/TLR4) signaling, a protective effect that could be transferred via FMT. The antihypertensive and metabolic benefits of 2'-FL in mice were accompanied by gut-brain axis modulation. These findings suggest that 2'-FL represents a promising dietary strategy for preventing hypertension-associated complications.\n --- END ACTUAL ABSTRACT FOR 41926238 ---\n\n- ERROR: You cited ID: 41683284 for the quote: \"Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase...

Beans (Phaseolus vulgaris) are rich in non-digestible carbohydrates and polyphenols, but whether kidney bean varieties differing in seed coat colour exert distinct effects on inflammation in obesity remains unclear. Objective: To determine whether supplementation of an obesogenic high-fat (HF) diet with white or dark red kidney beans modulates gut microbiota, SCFAs, and intestinal, systemic, and neuroinflammatory outcomes. Methods: Male C57Bl/6N mice (n = 12/group) were fed a basal diet (BD; modified AIN-93G), an HF diet (60% kcal from fat), or an HF diet supplemented with 15% cooked white (HF + WK) or dark red kidney beans (HF + DK) for nine weeks. Outcomes included cecal microbiota composition, predicted KEGG pathways with taxon contributors mapped with BURRITO (a tool for linking predicted microbial functions to contributing taxa), and SCFA-related pathways; cecal and fecal SCFA concentrations; colon histomorphometry and expression of gut barrier junction and inflammatory genes; serum cytokines and adipose hormones; and hippocampal inflammatory and barrier genes. Results: Mice consuming bean-supplemented HF diets had higher microbial diversity, enrichment of SCFA-producing taxa (Prevotella, Lactobacillus, Muribaculaceae), and lower obesity-associated genera versus HF alone (Mucispirillum, rc4-4). Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase in both bean groups versus HF and BD, and butyrate kinase in HF + DK versus BD. Bean supplementation attenuated HF-induced reduction of goblet cells and systemic interleukin (IL)-10. The HF + DK group had lower colonic tumour necrosis factor (TNF)-\u03b1 and partially attenuated hippocampal IL-6. SCFAs were inversely associated with systemic and neuroinflammatory markers in HF + DK mice. Conclusions: Kidney bean supplementation mitigated HF diet-induced intestinal, systemic, and neuroinflammatory disturbances in male mice, with microbiota and SCFA modulation. Further, dark red beans exerted stronger anti-inflammatory effects, highlighting the role of seed coat colour in bean-mediated obesity outcomes.\n --- END ACTUAL ABSTRACT FOR 41683284 ---\n\n- ERROR: You cited ID: 41403319 for the quote: \"In the hippocampus, it reduced neuronal loss, upregulated synaptic plasticity-related genes (Bdnf and Snap25), and suppressed neuroinflammation through inhibition of microglial activation and the TLR4/Myd88 signaling pathway.

However, its mechanisms of protection against age-related cognitive decline, especially those mediated via the gut-brain axis, are not fully understood. This study investigated the role of kaempferol in alleviating D-galactose-induced brain aging and elucidated its functional mechanisms related to gut microbiota composition, microbial metabolite production, and intestinal barrier integrity. An aging mouse model was induced by D-galactose and subsequently treated with kaempferol. Results revealed that kaempferol significantly ameliorated anxiety-like behaviors and spatial working memory deficits in D-galactose-treated mice. In the hippocampus, it reduced neuronal loss, upregulated synaptic plasticity-related genes (Bdnf and Snap25), and suppressed neuroinflammation through inhibition of microglial activation and the TLR4/Myd88 signaling pathway. Importantly, kaempferol restored intestinal barrier integrity, as indicated by increased expression of colonic MUC2 and tight junction proteins (Zo-1 and Occludin). It also markedly reshaped gut microbiota composition by enriching beneficial genera such as Faecalibaculum and Akkermansia, which correlated with elevated fecal propionate and butyrate levels, and a reduction in serum LPS. Our findings demonstrate that kaempferol mitigates D-galactose-induced cognitive impairment by modulating gut microbiota, increasing beneficial SCFA production, enhancing gut barrier function, and subsequently inhibiting systemic and neuroinflammation. This study provides mechanistic support for kaempferol as a dietary intervention strategy to promote brain health via the gut-brain axis.\n --- END ACTUAL ABSTRACT FOR 41403319 ---\n\n- ERROR: You cited ID: 41177025 for the quote: \"BPA exposure altered the cognitive task performances... coupled with reduced SCFAs levels (acetate; 32.48 \u00b1 8.48, and butyrate; 28.16 \u00b1 9.86).\"\n FACT: Ellipses (...) are strictly forbidden.

However, studies assessed its impact on cognitive performance at environmentally unrealistic doses. Nevertheless, the exact mechanism underlying the neurobehavioral phenotype, linking the role of gut microbiota is poorly understood. Here, we evaluated the effects of environmentally plausible dose of BPA-exposure on cognitive task performances with the functional analysis of gut metagenome to elucidate the role of microflora-gut-brain axis in behavioural regulation. Swiss albino mice were exposed to BPA for 5 weeks assessed for working and spatial navigation task performances. qRT-PCR based gene expression, histological investigation, gut permeability, molecular and biochemical markers of neuro-inflammation, leaky gut, oxido-nitrosative stress and 16\u202fs rRNA gene based metagenomics with functional analysis were performed.

It is known that the microbiota-gut-brain-axis plays a role in the pathogenesis, but the pathways are not fully understood yet. To elucidate the role of dietary fibre supplementation on this axis in a 5xFAD mouse model of Alzheimer\u00b4s disease, a feeding trial with an inulin supplement was conducted.

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\"Microbiota-derived acetate can alleviate neurological inflammation and neurodegeneration induced by hypoxia via the upregulation of brain-derived neurotrophic factor (BDNF).\"\n\nThe evidence provided confirms that microbiota-derived acetate, often modulated by probiotics or prebiotics, is associated with the alleviation of hypoxia-induced (including chronic intermittent hypoxia and hypobaric hypoxia) neuroinflammation and cognitive impairment. Mechanisms involve the restoration of BDNF expression and modulation of neuroinflammatory pathways, such as the inhibition of microglial activation. While acetate is frequently cited as a mediator, the causal chain involving acetate specifically as the sole upstream trigger for BDNF upregulation in all hypoxia models requires careful interpretation of the cited studies.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe hypothesis that gut microbiota-derived acetate mitigates hypoxia-related neurodegeneration and neuroinflammation through BDNF upregulation is supported by current preclinical evidence. Specifically, hypoxia induces gut dysbiosis, leading to diminished acetate production, while acetate supplementation or probiotic-mediated acetate restoration suppresses microglial activation and rescues BDNF levels to improve cognitive outcomes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurological resilience is tightly linked to the integrity of the gut-brain axis. Hypoxia, whether in the form of hypobaric conditions or chronic intermittent hypoxia, disrupts gut ecological balance, leading to systemic and central inflammation. Recent studies indicate that this hypoxic insult results in a marked depletion of short-chain fatty acids (SCFAs), with acetate frequently identified as a critical metabolite. \n\nMechanistically, the restoration of acetate levels\u2014either through targeted bacterial supplementation or direct administration\u2014acts as a neuroprotective signal. Acetate functions as a substrate for metabolic homeostasis and modulates histone deacetylase (HDAC) activity, influencing gene expression profiles associated with synaptic plasticity. The upregulation of brain-derived neurotrophic factor (BDNF) is a convergent downstream event across multiple models of neurodegeneration, where acetate-dependent restoration of metabolic cross-feeding or direct signaling mitigates neuroinflammatory cytokines like TNF-\u03b1 and IL-1\u03b2. This pathway facilitates the recovery of neuronal function following hypoxic challenges.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Microbiota-derived acetate can function as a \"dual-track\" regulator, restoring gut ecological balance while engaging in stress-adapted metabolic reprogramming.\n* Hypoxia-induced cognitive impairment is significantly linked to a reduction in the abundance of specific beneficial taxa like *Bifidobacterium pseudolongum*.\n* The effects of acetate are not limited to metabolic support but extend to direct suppression of hippocampal microglial activation and neuronal PANoptosis.\n* Dietary intervention, such as the use of acetylated starches, provides a sustained microbial source of acetate that can attenuate long-term neurological deficits.\n* Acetate restoration functions as a therapeutic node by modulating Class I histone deacetylases, thereby altering the chromatin landscape to favor neuroplasticity.\n* Preclinical models consistently demonstrate that acetate supplementation reproduces the anti-neuroinflammatory effects observed with probiotic administration.\n* The systemic-to-central axis is highly sensitive to acetate concentrations, influencing the activation state of innate immune cells in the hippocampus.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"31146971": "ID: 31146971\nTitle: Mononuclear phagocytes orchestrate prolyl hydroxylase inhibition-mediated renoprotection in chronic tubulointerstitial nephritis.\nAbstract: Prolyl hydroxylase domain enzyme inhibitors (PHDIs) stabilize hypoxia-inducible factors (HIFs), and are protective in models of acute ischemic and inflammatory kidney disease. Whether PHDIs also confer protection in chronic inflammatory kidney disease models remains unknown. Here we investigated long-term effects of PHDI treatment in adenine-induced nephropathy as a model for chronic tubulointerstitial nephritis. After three weeks, renal dysfunction and tubulointerstitial damage, including proximal and distal tubular injury, tubular dilation and renal crystal deposition were significantly attenuated in PHDI-treated (the isoquinoline derivative ICA and Roxadustat) compared to vehicle-treated mice with adenine-induced nephropathy. Crystal-induced renal fibrosis was only partially diminished by treatment with ICA. Renoprotective effects of ICA treatment could not be attributed to changes in adenine metabolism or urinary excretion of the metabolite 2,8-dihydroxyadenine. ICA treatment reduced inflammatory infiltrates of F4/80+ mononuclear phagocytes in the kidneys and supported a regulatory, anti-inflammatory immune response. Furthermore, interstitial deposition of complement C1q was decreased in ICA-treated mice fed an adenine-enriched diet. Tubular cell-specific HIF-1\u03b1 and myeloid cell-specific HIF-1\u03b1 and HIF-2\u03b1 expression were not required for the renoprotective effects of ICA. In contrast, depletion of mononuclear phagocytes with clodronate largely abolished the nephroprotective effects of PHD inhibition. Thus, our findings indicate novel and potent systemic anti-inflammatory properties of PHDIs that confer preservation of kidney function and structure in chronic tubulointerstitial inflammation and might counteract kidney disease progression.",

Hippophae rhamnoides, Prunus armeniaca, and Rhodiola imbricata, the indigenous plants of Indian Trans-Himalaya are widely used in traditional Tibetan and Amchi system of medicine. These are rich sources of diverse bioactive metabolites having prophylactic and therapeutic uses against a wide array of neurodegenerative diseases. The objective of this study was to elucidate the prophylactic and neuroprotective efficacy of formulated phytococktail (PC) against simulated HH-induced neurodegeneration in male Sprague Dawley (SD) rats. Materials and Methods: A PC containing H. rhamnoides fruit pulp, P. armeniaca fruit pulp, and R. imbricata dry root extract (100:50:1) was formulated. The neuroprotective efficacy of PC was evaluated in male SD rats following exposure to 7 day HH at simulated altitude (25,000 ft, 282\u2009mm Hg). Rats were divided into four groups viz., normoxia group (NOR), normoxic group treated with PC (NORPC), 7 day hypoxic group treated with vehicle (7DH), and 7 day hypoxic group treated with PC (7DHPC). Memory impairment and neuromorphological alterations were measured. Targeted protein expression was analyzed by immunoblotting study. Results: PC supplementation significantly reduced the oxidative stress markers during exposure to HH. Spatial memory impairment by HH was significantly ameliorated by PC. HH-induced augmented pyknosis, decreased dendritic arborization, and increased Hoechst-positive neurons in hippocampal CA3 region were significantly ameliorated by PC. Immunoblotting study showed upregulation of BDNF and TrkB expression by PC. PC also prevented the hippocampal neurodegeneration by activating the PI3K/AKT signaling pathway, which leads to GSK-3\u03b2 inactivation by its phosphorylation and alleviation of hippocampal Caspase3 expression leading to inhibition of apoptotic neuronal cell death. Conclusion: The present study advocates the potential role of PC as an effective neuroprotective supplement in preventing HH-induced neurodegeneration. Activation of the PI3K/Akt pathway through BDNF/TrkB interaction following PC supplementation after exposure to HH inhibits hippocampal neuronal apoptosis and memory impairment.",

On the basis of evidence that PKC\u03b2 and mitochondrial oxidative stress are involved in several cardiovascular and metabolic disorders, we hypothesized that PKC\u03b2 and mitochondrial ROS (mitoROS) signaling contribute to enhanced pulmonary vasoconstriction in neonatal rats exposed to CH. To test this hypothesis, we examined effects of the PKC\u03b2 inhibitor LY-333,531, the ROS scavenger 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine (TEMPOL), and the mitochondrial antioxidants mitoquinone mesylate (MitoQ) and (2-(2,2,6,6-tetramethylpiperidin-1-oxyl-4-ylamino)-2-oxoethyl)triphenylphosphonium chloride (MitoTEMPO) on vasoconstrictor responses in saline-perfused lungs (in situ) or pressurized pulmonary arteries from 2-wk-old control and CH (12-day exposure, 0.5 atm) rats. Lungs from CH rats exhibited greater basal tone and vasoconstrictor sensitivity to 9,11-dideoxy-9\u03b1,11\u03b1-methanoepoxy prostaglandin F2\u03b1 (U-46619). LY-333,531 and TEMPOL attenuated these effects of CH, while having no effect in lungs from control animals. Basal tone was similarly elevated in isolated pulmonary arteries from neonatal CH rats compared with control rats, which was inhibited by both LY-333,531 and mitochondria-targeted antioxidants. Additional experiments assessing mitoROS generation with the mitochondria-targeted ROS indicator MitoSOX revealed that a PKC\u03b2-mitochondrial oxidant signaling pathway can be pharmacologically stimulated by the PKC activator phorbol 12-myristate 13-acetate in primary cultures of pulmonary artery smooth muscle cells (PASMCs) from control neonates. Finally, we found that neonatal CH increased mitochondrially localized PKC\u03b2 in pulmonary arteries as assessed by Western blotting of subcellular fractions. We conclude that PKC\u03b2 activation leads to mitoROS production in PASMCs from neonatal rats. Furthermore, this signaling axis may account for enhanced pulmonary vasoconstrictor sensitivity following CH exposure.NEW & NOTEWORTHY This research demonstrates a novel contribution of PKC\u03b2 and mitochondrial reactive oxygen species signaling to increased pulmonary vasoconstrictor reactivity in chronically hypoxic neonates. The results provide a potential mechanism by which chronic hypoxia increases both basal and agonist-induced pulmonary arterial smooth muscle tone, which may contribute to neonatal pulmonary hypertension.",

Based on prior studies in patients with SA and animal models of SA, the objective of this study was to evaluate the role of PKC\u03b2 and mitochondrial reactive oxygen species (mitoROS) in mediating enhanced pulmonary vasoconstrictor reactivity after IH. We hypothesized that PKC\u03b2 mediates vasoconstriction through interaction with the scaffolding protein PICK1 (protein interacting with C kinase 1), activation of mitochondrial ATP-sensitive potassium channels (mitoKATP), and stimulated production of mitoROS. We further hypothesized that this signaling axis mediates enhanced vasoconstriction and pHTN after IH. Rats were exposed to IH or sham conditions (7 h/d, 4 wk). Chronic oral administration of the antioxidant Tempol or the PKC\u03b2 inhibitor LY-333531 abolished IH-induced increases in right ventricular systolic pressure and right ventricular hypertrophy. Furthermore, scavengers of O2- or mitoROS prevented enhanced PKC\u03b2-dependent vasoconstrictor reactivity to endothelin-1 in pulmonary arteries from IH rats. In addition, this PKC\u03b2/mitoROS signaling pathway could be stimulated by the PKC activator PMA in pulmonary arteries from control rats, and in both rat and human pulmonary arterial smooth muscle cells. These responses to PMA were attenuated by inhibition of mitoKATP or PICK1. Subcellular fractionation and proximity ligation assays further demonstrated that PKC\u03b2 acutely translocates to mitochondria upon stimulation and associates with PICK1. We conclude that a PKC\u03b2/mitoROS signaling axis contributes to enhanced vasoconstriction and pHTN after IH. Furthermore, PKC\u03b2 mediates pulmonary vasoconstriction through interaction with PICK1, activation of mitoKATP, and subsequent mitoROS generation.",

The remarkable neurotrophic activity of Gelidium amansii, which has been reported consistently in a series of our previous studies, inspired us to investigate whether this popular agarophyte could protect against hypoxia/reoxygenation (H/R)-induced oxidative injury in hippocampal neurons. The primary culture of hippocampal neurons challenged with H/R suffered from a significant loss of cell survival, accompanied by apoptosis and necrosis, DNA damage, generation of reactive oxygen species (ROS), and dissipation of mitochondrial membrane potential (\u0394\u03a8m), which were successfully attenuated when the neuronal cultures were preconditioned with ethanolic extract of G. amansii (GAE). GAE also attenuated an H/R-mediated increase of BAX and caspase 3 expressions while promoting Bcl-2 expression. Moreover, the expression of N-methyl-d-acetate receptor subunit 2B (GluN2B), an extrasynaptic glutamate receptor, was significantly repressed, while synaptic GluN2A expression was preserved in GAE-treated neurons as compared to those without GAE intervention. Together, this study demonstrates that GAE attenuated H/R-induced oxidative injury in hippocampal neurons through, at least in part, a potential neuroprotective mechanism that involves inhibition of GluN2B-mediated excitotoxicity and suppression of ROS production, and suggests that this edible seaweed could be a potential source of bioactive metabolites with therapeutic significance against oxidative stress-related neurodegeneration, including ischemic stroke and neurodegenerative diseases.",
"32382851": "ID: 32382851\nTitle: Evans Blue Might Produce Pathologically Activated Neuroprotective Effects via the Inhibition of the P2X4R/p38 Signaling Pathway.\nAbstract: The main pathological features of ischemic stroke include neuronal damage and blood-brain barrier (BBB) dysfunction. Previous studies have shown that Evans Blue, a dye used to probe BBB integrity, could enter the brain only during the pathological status of ischemic stroke, indicating the potential pathologically activated therapeutic use of this chemical to treat ischemic stroke. In this study, we have reported that Evans Blue could produce in vitro neuroprotective effects against iodoacetic acid (IAA)-induced hypoxia neuronal death in HT22 cells. We further found that P2X\u00a0purinoreceptor 4 (P2X4R), a subtype of ATP-gated\u00a0cation\u00a0channel, was expressed in HT22 cells. Evans Blue could prevent IAA-induced increase of P2X4R mRNA and protein expression. Interestingly, shRNA of P2X4R could protect against IAA-induced activation of p38, and SB203580, a specific inhibitor of p38, could reverse IAA-induced neurotoxicity, indicating that p38 is a downstream signaling molecule of P2X4R. Molecular docking analysis further demonstrated the possible interaction between Evans Blue and the ATP binding site of P2X4R. Most importantly, pre-treatment of Evans Blue could largely reduce neurological and behavioral abnormity, and decrease brain infarct volume in middle cerebral artery occlusion/reperfusion (MCAO) rats. All these results strongly suggested that Evans Blue could exert neuroprotective effects via inhibiting the P2X4R/p38 pathway, possibly by acting on the ATP binding site of P2X4R, indicating that Evans Blue might be further developed as a pathologically activated therapeutic drug against ischemic stroke.",

Merr. belongs to the family Menispermaceae. It is called LeZhe and is widely used as a kind of folk medicine especially in the Tibetan Plateau of China. T. sinensis has the functions of clearing away heat and detoxification, dispelling wind and dredging collaterals, calming and soothing the nerves. T. sinensis is an effective medicine for the prevention and treatment of aging diseases such as Alzheimer's disease (AD) in the Tibetan Plateau of China, whereas its material basis and underlying mechanisms are not clear. The aim of this study was to investigate the material basis and potential mechanisms of T. sinensis in the treatment of AD by using network pharmacology and molecular docking. In this study, targets were collected from DrugBank database, Therapeutic Target Database (TTD) and literatures reports for the treatment of AD. Compounds were searched by literatures and systematic separation from T. sinensis. The molecular docking experiment was carried out by using Autodock Vina software to screen the bioactive compounds in T. sinensis and target proteins for AD. Then, the \"compound-target network\" was constructed by Cytoscape software. The drug-like properties of the active compounds were analyzed by pKCSM performs, and the protein-protein interaction (PPI) network was constructed by Search Tool for the Retrieval of Interacting Genes/Proteins (STRING). The Kyoto Encyclopedia of Genes and Genomes (KEGG) target pathway enrichment analysis was carried out by Database for Annotation, Visualization and Integrated Discovery (DAVID). Furthermore, the protective effect of neurons of two active compounds were verified with the injury cell model of PC12 and primary hippocampus neurons induced by A\u03b225-35. Finally, the key proteins of related pathways were quantitatively analyzed with Western blot method. In total, 105 compounds and 38 targets have been screened. The main active compounds contained berberine, which belongs to alkaloids, Aurantiamide acetate, N-P-coumaroyltyramine, which belongs to amides, Trans-syringin and 3-demethyl-phillyrin, which belongs to phenylpropanoids. The targets covered inflammation-related proteins, including Protein kinase B (AKT), Phosphoinositide 3-kinase (PI3K), Tyrosine-protein kinase JAK1 (JAK1), mammalian target of rapamycin (mTOR), tumor necrosis factor alpha (TNF-\u03b1), Neuronal NOS (NOS1), and cholinergic function-related proteins, including \u03b14-Nicotinic acetylcholine receptor (\u03b14 nAChR), Muscarinic acetylcholine receptor M1 (Muscarnic M1). Inflammation and cholinergic dysfunction were the center of the network and occupy a dominant position. And the results of enrichment analysis shown the pathways mainly contained phosphoinositide-3-kinase/Akt (PI3K/Akt) signal pathway, neurotrophic factors (NTFs) signal pathway, Hypoxia-inducible factor 1 (HIF-1) signal pathway, mechanistic Target of Rapamycin (mTOR) signal pathway, Tumor necrosis factor (TNF) signal pathway, insulin resistance (IR). The results of in vitro assays showed that the tested compounds could significantly improve the survival rate and inhibit the apoptosis of PC12\u00a0cells and primary hippocampal neurons injured by A\u03b225-35. Western blot results showed that T. sinensis had a significant effect on the expression of protein PI3K and Akt. Our results revealed that T. sinensis could prevent and treat AD through a multi-compound-multi-target-multi-pathway regulatory network. Our work also expected to provide new ideas and theoretical bases for searching for the active compounds in T. sinensis and potential mechanism in the prevention and treatment of AD by the network pharmacology and molecular docking.

However, the downstream mechanisms underlying the TRPM7-mediated processes in physiology and pathophysiology remain unclear. In this study, we employed a mouse model of hypoxic-ischemic brain cell death which mimics the pathophysiology of hypoxic-ischemic encephalopathy (HIE). HIE is a major public health issue and an important cause of neonatal deaths worldwide; however, the available treatments for HIE remain limited. Its survivors face life-long neurological challenges including mental retardation, cerebral palsy, epilepsy and seizure disorders, motor impairments, and visual and auditory impairments. Through a proteomic analysis, we identified calcium/calmodulin-dependent protein kinase II (CaMKII) and phosphatase calcineurin as potential mediators of cell death downstream from TRPM7 activation. Further analysis revealed that TRPM7 mediates cell death through CaMKII, calmodulin, calcineurin, p38, and cofilin cascade. In vivo, we found a significant reduction of brain injury and improvement of short- and long-term functional outcomes after HI after administration of specific TRPM7 blocker waixenicin A. Our data demonstrate a molecular mechanism of TRPM7-mediated cell death and identifies TRPM7 as a promising therapeutic and drug development target for HIE.",

Unfortunately, there are currently no known treatment options to minimize ischemia-induced neural damage. We previously showed the neuroprotective/neurogenic potential of a histone deacetylase inhibitor (HDACi), sodium butyrate (SB), in a neonatal HI rat pup model. The aim of the present study was to examine the capacity of another HDACi-Trichostatin A (TSA)-to stimulate neurogenesis in the subgranular zone of the hippocampus. We also assessed some of the cellular/molecular processes that could be involved in the action of TSA, including the expression of neurotrophic factors (glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), and brain-derived neurotrophic factor (BDNF)) as well as the TrkB receptor and its downstream signalling substrate- cAMP response element-binding protein (CREB). Seven-day-old rat pups were subjected to unilateral carotid artery ligation followed by hypoxia for 1 h. TSA was administered directly after the insult (0.2 mg/kg body weight). The study demonstrated that treatment with TSA restored the reduced by hypoxia-ischemia number of immature neurons (neuroblasts, BrdU/DCX-positive) as well as the number of oligodendrocyte progenitors (BrdU/NG2+) in the dentate gyrus of the ipsilateral damaged hemisphere. However, new generated cells did not develop the more mature phenotypes. Moreover, the administration of TSA stimulated the expression of BDNF and increased the activation of the TrkB receptor. These results suggest that BDNF-TrkB signalling pathways may contribute to the effects of TSA after neonatal hypoxic-ischemic injury.",

Casticin, a compound purified from the Chinese herb Viticis Fructus, has been proved effective in preventing inflammation and fibrosis in previous studies. However, the effect of casticin on synovial fibrosis in KOA is not clear. In present study, we aimed to investigate how did casticin affect synovial fibrosis on monoiodoacetic acid (MIA)-induced KOA in rats. The MIA-induced knee osteoarthritis model and lipopolysaccharide (LPS) stimulated primary synovial fibroblasts inflammation model were established. Pathological and morphological changes in synovial tissue were observed by H&E and sirius red staining. The hypoxia of synovium was detected by pimonidazole staining and immunohistochemistry of hypoxia-inducible factors 1\u03b1 (HIF-1\u03b1). The levels of nucleotide oligomerization domain-like receptor protein 3 (NLRP3) inflammasome components, fibrogenic markers (TGF-\u03b2, COL1A1 and TIMP1) and inflammatory cytokines were examined by western blotting, qRT-PCR or ELISA in both KOA rat models and primary synovial fibroblasts. Our data suggested that casticin improved hypoxia and inflammation in synovium tissue, as well the synovial fibrosis in rats. Besides, casticin inhibited the activation of NLRP3 inflammasome in MIA-induced KOA rats and synovial fibroblasts. In conclusion, our findings demonstrated that casticin alleviated MIA-induced KOA by inhibiting of HIF-1\u03b1/NLRP3 inflammasome activation. Therefore, casticin could be a potential treatment strategy for KOA.",

Thus, compounds with antioxidant property might confer protection against anoxic stress-induced brain injuries. In this study, we further examined the protective effect of methyl jasmonate (MJ), a potent anti-stress agent against anoxic stress-induced convulsions in mice. Thirty-six male Swiss mice randomized into six groups (n=6) were given MJ (25, 50 and 100\u00a0mg/kg, i.p.) or vehicle (10\u00a0mL/kg, i.p.) 30\u00a0min before 15\u00a0min daily exposure to anoxic stress for 7\u00a0days. The latency(s) to anoxic convulsion was recorded on day 7. The blood glucose and serum corticosterone levels were measured afterwards. The brains were also processed for the determination of malondialdehyde, nitrite, and glutathione levels. Methyl jasmonate (MJ) delayed the latency to anoxic convulsion and reduced the blood glucose and serum corticosterone levels. The increased malondialdehyde and nitrite contents accompanied by decreased glutathione concentrations in mice with anoxic stress were significantly attenuated by MJ. These findings further showed that MJ possesses anti-stress property via mechanisms relating to the reduction of serum contents of corticosterone and normalization of brain biomarker levels of oxidative stress in mice with anoxic stress.",
"32994545": "ID: 32994545\nTitle: Waixenicin A, a marine-derived TRPM7 inhibitor: a promising CNS drug lead.\nAbstract: Ion channels are the third largest class of targets for therapeutic drugs. The pharmacology of ion channels is an important research area for identifying new treatment options for human diseases. The past decade or so has seen increasing interest in an ion channel protein belonging to the transient receptor potential (TRP) family, namely the melastatin subfamily member 7 (TRPM7), as an emerging drug target. TRPM7 is a bifunctional protein with a\u00a0magnesium and calcium-conducting divalent ion channel fused with an active kinase domain. TRPM7 is ubiquitously expressed in human tissues, including the brain, and regulates various cell biology processes such as magnesium and calcium homeostasis, cell growth and proliferation, and embryonic development. TRPM7 provides a link between cellular metabolic status and intracellular calcium homeostasis in neurons due to TRPM7's unique sensitivity to fluctuating intracellular Mg\u00b7ATP levels. Thus, the protein plays a key role in ischemic and hypoxic neuronal cell death and brain injury, and is one of the key nonglutamate mechanisms in cerebral ischemia and stroke. Currently, the most potent and specific TRPM7 inhibitor is waixenicin A, a xenicane diterpenoid from the Hawaiian soft coral Sarcothelia edmondsoni. Using waixenicin A as a pharmacological tool, we demonstrated that TRPM7 is involved in promoting neurite outgrowth in vitro. Most recently, we found that waixenicin A reduced hypoxic-ischemic brain injury and preserved long-term behavioral outcomes in mouse neonates. We here suggest that TRPM7 is an emerging drug target for CNS diseases and disorders, and waixenicin A is a viable drug lead for these disorders.",

The naturally occurring phytosterol, stigmasterol (ST) is known for its potential role in cholesterol homeostasis and neuronal development. However, the ability of ST to protect against the induced excitotoxicity in hippocampal neurons has not been investigated yet. The present study aimed to investigate whether ST could protect against hypoxia/reoxygenation (H/R)-induced excitotoxicity in hippocampal neurons. After H/R, neurons were initially subjected to trypan blue exclusion assay for the assessment of cell viability. Live staining using fluorescence dyes namely JC-1 (5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide), DCFDA (2',7'-dichlorofluorescein diacetate) and FM1-43 (N-(3-triethylammoniumpropyl)-4-(4-(dibutylamino)styryl) were used to measure MMP, ROS and synaptic vesicle pool size. Immunostaining was performed to analyze the expression levels of vesicular glutamate transporter 1 (VGLUT1), N-methyl-D-acetate receptor subunit 2B (GluN2B), LC3BII, p62, and PTEN induced protein kinase 1 (PINK1) in neuron after H/R. Western blotting was carried out to measure the protein expression of GluN2B. The molecular dynamics simulation was employed to elucidate the LXR\u03b2 agonistic conformation of ST. Pre-incubation of neuronal cultures with ST (20 \u03bcM) protected against excitotoxicity, and attenuated reactive oxygen species (ROS) generation, double-stranded DNA break, and mitochondrial membrane potential (MMP) loss. ST treatment also resulted in the downregulation of the expressions of VGLUT1 and GluN2B and the reduction of the size of recyclable synaptic vesicle (SV) pool. Like LXR\u03b2 agonist GW3695, ST suppressed the expression of GluN2B. Furthermore, ST induced mitophagy through upregulating the expressions of LC3BII, p62, and PINK1. The molecular simulation study showed that ST interacted with the ligand binding domain of liver X receptor \u03b2 (LXR\u03b2), a known binding receptor of ST, through multiple hydrogen bonding. Collectively, these findings revealed that ST exhibited a promising neuroprotective effect by regulating both pre- and post-synaptic events following H/R, particularly, attenuation of GluN2B-mediated excitotoxicity and oxidative stress, and induction of mitophagy, and suggested that ST might be a therapeutic promise against ischemic stroke and its associated neurological disorders.",

Previous studies suggested that epigenetic modifications are the culprits for this condition. Here, we set out to determine how hypobaric hypoxia mediates epigenetic modifications and how this condition worsens neurodegeneration and memory loss in rats. In the current study, different duration of hypobaric hypoxia exposure showed a discrete pattern of\u00a0histone acetyltransferases\u00a0and histone deacetylases (HDACs)\u00a0gene\u00a0expression in the hippocampus when compared with control rat brains. The level of acetylation sites in histone H2A, H3\u00a0and H4 was significantly decreased under hypobaric hypoxia exposure compared to the control rat's hippocampus. Additionally, inhibiting the HDAC family with sodium butyrate administration (1.2\u2009g/kg body weight) attenuated neurodegeneration and memory loss in hypobaric hypoxia-exposed rats. Moreover, histone acetylation increased at the promoter regions of brain-derived neurotrophic factor\u00a0(BDNF);\u00a0thereby its protein expression was enhanced significantly in hypobaric hypoxia exposed rats treated with HDAC inhibitor compared with hypoxic rats. Thus, BDNF expression upregulated cAMP-response element binding protein (CREB) phosphorylation by stimulation of PI3K/GSK3\u03b2/CREB axis, which counteracts hypobaric hypoxia-induced spatial memory impairment. In conclusion, these results suggested that sodium butyrate is a novel therapeutic agent for the treatment of spatial memory loss associated with hypobaric hypoxia, and also further studies are warranted to explore specific HDAC inhibitors in this condition.",

Here, we evaluate the bioactivity of essential oil and the various polarity-based solvent partitioned fractions obtained from Curcuma caesia for anti-amnesia, anxiolytic and antidepressant activities using Elevated plus maze and Morris water maze models. The cold maceration technique using methanol was adopted for extraction from dried powdered rhizomes and essential oil was extracted by hydrodistillation method. Partitioning of the methanolic extract based on solvent polarity by hexane, ethyl acetate, and methanol was continued, followed by column chromatography of the ethyl acetate fraction. Suspensions were prepared for fractions (dissolved in distilled water) and essential oil (dissolved in tween 20) at 200 mg/kg and 400 mg/kg after acute toxicity study and were orally administered to Wistar albino female rats after the orientation of hypoxia by sodium nitrite (50 mg/kg) and amnesia by scopolamine (1 mg/kg). Behavioural observations, biochemical and histopathological examinations were carried out for all the treated groups. Diazepam (12 mg/kg) and galantamine (3 mg/kg) were used as standard drugs for this study against hypoxia and amnesia. Data acquired from behavioural, biochemical (acetylcholinesterase, myeloperoxidase, superoxide dismutase, reduced glutathione, catalase) and histopathological studies have illustrated that fraction II acquires highly significant memory-enhancing, anxiolytic and antidepressant effects. Rest fractions (I and III) and essential oil showed moderate efficacy. In prospects, identification of active molecules from the most active fraction (fraction II) and further studies on a molecular basis would substantiate its specific mechanism of neuroprotective action.",

Common treatments for SDB include adenotonsillectomy and nocturnal continuous positive airway pressure (CPAP), but adenotonsillectomy is an invasive surgical procedure, and CPAP is rarely well-tolerated. Further, there is no current consensus on the ability of these treatments to improve cognitive function. Several double-blind, randomised controlled trials (RCTs) have demonstrated the efficacy of montelukast, a safe, well-tolerated anti-inflammatory agent, as a treatment for airway obstruction and reducing adenoid size for children who do not have SCA. However, we do not yet know whether montelukast reduces adenoid size and improves cognition function in young children with SCA. The Study of Montelukast In Children with Sickle Cell Disease (SMILES) is a 12-week multicentre, double-blind, RCT. SMILES aims to recruit 200 paediatric patients with SCA and SDB aged 3-7.99\u2009years to assess the extent to which montelukast can improve cognitive function (i.e. processing speed) and sleep and reduce adenoidal size and white matter damage compared to placebo. Patients will be randomised to either montelukast or placebo for 12\u2009weeks. The primary objective of the SMILES trial is to assess the effect of montelukast on processing speed in young children with SCA. At baseline and post-treatment, we will administer a cognitive evaluation; caregivers will complete questionnaires (e.g. sleep, pain) and measures of demographics. Laboratory values will be obtained from medical records collected as part of standard care. If a family agrees, patients will undergo brain MRIs for adenoid size and other structural and haemodynamic quantitative measures at baseline and post-treatment, and we will obtain overnight oximetry. Findings from this study will increase our understanding of whether montelukast is an effective treatment for young children with SCA.

Dichloroacetic acid (DCA) can inhibit pyruvate dehydrogenase kinase (PDK). Moreover, DCA has been indicated with the capability of increasing mitochondrial pyruvate uptake and promoting oxidation of glucose in the course of glycolysis, thereby improving the activity of pyruvate dehydrogenase (PDH). As a result, pyruvate flow is promoted into the tricarboxylic acid cycle to expedite ATP production. DCA has a protective effect on IS and brain ischemia/reperfusion (I/R) injury, but the specific mechanism remains unclear. This study adopted a transient middle cerebral artery occlusion (MCAO) mouse model for simulating IS and I/R injury in mice. We investigated the mechanism by which DCA regulates glycolysis and protects the oxidative damage induced by I/R injury through the PDK2-PDH-Nrf2 axis. As indicated from the results of this study, DCA may improve glycolysis, reduce oxidative stress and neuronal death, damage the blood-brain barrier, and promote the recovery of oxidative metabolism through inhibiting PDK2 and activating PDH. Additionally, DCA noticeably elevated the neurological score and reduced the infarct volume, brain water content, and necrotic neurons. Moreover, as suggested from the results, DCA elevated the content of Nrf2 as well as HO-1, i.e., the downstream antioxidant proteins pertaining to Nrf2, while decreasing the damage of BBB and the degradation of tight junction proteins. To simulate the condition of hypoxia and ischemia in vitro, HBMEC cells received exposure to transient oxygen and glucose deprivation (OGD). The DCA treatment is capable of reducing the oxidative stress and blood-brain barrier of HBMEC cells after in vitro hypoxia and reperfusion (H/R). Furthermore, this study evidenced that HBMEC cells could exhibit higher susceptibility to H/R-induced oxidative stress after ML385 application, the specific inhibitor of Nrf2. Besides, the protection mediated by DCA disappeared after ML385 application. To sum up, as revealed from the mentioned results, DCA could exert the neuroprotective effect on oxidative stress and blood-brain barrier after brain I/R injury via PDK2-PDH-Nrf2 pathway activation. Accordingly, the PDK2-PDH-Nrf2 pathway may play a key role and provide a new pharmacology target in cerebral IS and I/R protection by DCA.",

Here, we evaluated whether delayed and short-term lithium treatment reduces brain infarction volume and improves electrophysiological and neurobehavioral outcomes following long-term recovery after cerebral ischemia and the possible contributions of lithium-mediated mechanisms of neuroplasticity. Male Sprague Dawley rats were subjected to right middle cerebral artery occlusion for 90\u00a0min, followed by 28\u00a0days of recovery. Lithium chloride (1 mEq/kg) or vehicle was administered via intraperitoneal infusion once per day at 24\u00a0h after reperfusion onset. Neurobehavioral outcomes and somatosensory evoked potentials (SSEPs) were examined before and 28\u00a0days after ischemia-reperfusion. Brain infarction was assessed using Nissl staining. Primary cortical neuron cultures were exposed to oxygen-glucose deprivation (OGD) and treated with 2 or 20\u00a0\u03bcM lithium for 24 or 48\u00a0h; subsequent brain-derived neurotrophic factor (BDNF), growth-associated protein-43 (GAP-43), postsynaptic density-95 (PSD-95), and synaptosomal-associated protein-25 (SNAP-25) levels were analyzed using western blotting. Compared to controls, lithium significantly reduced infarction volume in the ischemic brain and improved electrophysiological and neurobehavioral outcomes at 28\u00a0days post-insult. In cultured cortical neurons, BDNF, GAP-43, and PSD-95 expression were enhanced by 24- and 48-h treatment with lithium after OGD. Lithium upregulates BDNF, GAP-43, and PSD-95, which partly accounts for its improvement of neuroplasticity and provision of long-term neuroprotection in the ischemic brain.Abbreviations: BDNF: brain-derived neurotrophic factor; ECM: extracellular matrix; EDTA: ethylenediaminetetraacetic acid; GAP-43: growth-associated protein-43; GSK-3\u03b2: glycogen synthase kinase-3\u03b2; HBSS: Hank's balanced salt solution; LCBF: local cortical blood perfusion; LDF: laser-Doppler flowmetry; MCAO: middle cerebral artery occlusion; MMP: matrix metalloproteinase; NMDA: N-methyl-D-aspartate; NMDAR: N-methyl-D-aspartate receptor; OCT: optimal cutting temperature compound; OGD: oxygen-glucose deprivation; PSD-95: postsynaptic density-95; SDS: sodium dodecyl sulfate; SNAP-25: synaptosomal-associated protein-25; SSEP: somatosensory evoked potential.",

Irisin and heat shock protein 70 (HSP70) are well known for their role in neuroprotection. The possible neuroprotective effects of fenofibrate on HFFD-induced cognitive dysfunction and the involvement of irisin and HSP70 in these effects were investigated in this study. Rats were divided into normal control, HFFD, dimethylsulfoxide+HFFD, and fenofibrate+HFFD groups. At the end of the experiment, fenofibrate treatment restored hippocampus histological characteristics to almost normal and improved HFFD-induced cognitive deficit. It reduced body weight gain and had hypolipidemic effects by significantly lowering total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels while increasing high-density lipoprotein cholesterol levels. It has antioxidant and anti-inflammatory effects as it significantly reduced the hippocampal malondialdehyde, interleukin-6, and tumor necrosis factor-alpha levels, while significantly increasing the reduced glutathione level. It prevented HFFD-induced hypoxia by significantly lowering hippocampal vascular endothelial growth factor and hypoxia-inducible factor-1 alpha levels. It significantly activated the hippocampal peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1\u03b1)/irisin/brain-derived neurotrophic factor pathway. It significantly increased hippocampal HSP70 while decreasing the HSP90 levels. It enhanced synaptic plasticity by significantly upregulating the hippocampal relative GluR1 gene expression. Furthermore, hippocampal irisin levels in the HFFD group were found to be positively correlated with cognitive function, hippocampal HSP70, and relative GluR1 gene expression levels, while negatively correlated with hippocampal HSP90 and HIF1\u03b1 levels. Therefore, fenofibrate may be used as a potential medication to treat HFFD-induced neurodegenerative disorders.",

However, the mechanisms still require further investigation. In this study, we found that the butanoate metabolism pathway exhibited significantly decreased and short chain fatty acid (SCFAs)-producing bacteria, especially butyrate-producing bacteria, were significantly decreased in fecal of neonatal hypoxic-ischemic brain damage (HIBD) rats. Surprisingly, Sodium butyrate (SB) treatment could ameliorate pathological damage both in the cerebral cortex and hippocampus and facilitate recovery of SCFAs-producing bacteria related to metabolic pathways in neonatal HIBD rats. Moreover, we found that in samples from SB treatment neonatal HIBD rats cortex with high levels of butyrate acid along with aberrant key crotonyl-CoA-producing enzymes ACADS levels were observed compared HIBD rats. We also demonstrated that a decrease in histone 3-lysine 9-crotonylation (H3K9cr) downregulated expression of the HIE-related neurotrophic genes Bdnf, Gdnf, Cdnf, and Manf in HIBD rats. Furthermore, SB restored H3K9cr binding to HIE-related neurotrophic genes. Collectively, our results indicate that SB contributes to ameliorate pathology of HIBD by altering gut microbiota and brain SCFAs levels subsequently affecting histone crotonylation-mediated neurotrophic-related genes expression. This may be a novel microbiological approach for preventing and treating HIE.",
"36682600": "ID: 36682600\nTitle: Delayed administration of Trichilia catigua A. Juss. Ethyl-acetate fraction after cerebral ischemia prevents spatial memory deficits, decreases oxidative stress, and impacts neural plasticity in rats.\nAbstract: Trichilia catigua A. Juss (Meliaceae) is used in Brazilian folk medicine to alleviate fatigue and emotional stress and improve memory. Previous studies from our laboratory reported that an ethyl-acetate fraction (EAF) of T. catigua that was given before cerebral ischemia in vivo prevented memory loss and reduced oxidative stress and neuroinflammation. Despite the value of these findings of a neuroprotective effect of T. catigua, treatment that was given immediately before or immediately after ischemia limits its clinical relevance. Thus, unknown is whether T. catigua possesses a specific time window of efficacy (TWE) when administered postischemia. Given continuity to previous studies, we investigated whether an EAF of T. catigua maintains its neuroprotective properties if treatment begins at different time windows of efficacy after ischemia. We also evaluated, for the first time, whether T. catigua possesses neuroplasticity/neurotrophic properties. Rats were subjected to transient global brain ischemia (TGCI) and then given a single dose of the EAF (400\u00a0mg/kg) or vehicle (1\u00a0ml/kg) orally 1, 4, or 6\u00a0h postischemia. The levels of protein PCG, GSH, and GSSG, and activity of SOD and CAT were assayed as markers of oxidative stress on the day after ischemia. In another experiment, naive rats underwent spatial learning training in a radial maze task and then subjected to TGCI. Delayed treatment with the EAF began 4 or 6\u00a0h later and continued for 7 days. Retrograde memory performance was assessed 10, 17, and 24 days postischemia. Afterward, brains were examined for neurodegeneration and neuronal dendritic morphology in the hippocampus and cerebral cortex. Another group received the EAF at 4\u00a0h of reperfusion, and 4 days later their brains were examined for GFAP and Iba-1 immunoreactivity. Lastly, ischemic rats received the EAF 4\u00a0h after ischemia and neural plasticity-related proteins, BDNF, SYN, PSD 95, and NeuN were measured in the hippocampus 7 and 14 days after ischemia. A single EAF administration 1, 4, or 6\u00a0h postischemia alleviated oxidative stress that was caused by ischemia, expressed as a reduction of the amount of the PCG and GSSG, normalization of the GSH/GSSG ratio, and the restoration of SOD activity. Ischemia caused the persistent loss of memory (i.e., amnesia), an outcome that was consistently ameliorated by treatment with the EAF that was initiated 4 or 6\u00a0h postischemia. The 4\u00a0h delay in EAF treatment positively impacted dendritic morphology in neurons that survived ischemia. TGCI reduced BDNF, SYN, PSD-95, and NeuN protein levels in the hippocampus and cerebral cortex. The EAF normalized SYN and PSD-95 protein levels. Ischemia-induced neurodegeneration and glial cell activation were not prevented by EAF treatment. The present study corroborates prior data that demonstrated the neuroprotective potential of T. catigua and extends these data by showing that the delayed administration of EAF postischemia effectively prevented memory impairment and decreased oxidative stress, dendritic deterioration, and synaptic protein loss within a TWE that ranged from 1 to 6\u00a0h. This specific TWE in preclinical research may have clinical relevance by suggesting the possible utility of this plant for the development of neuroprotective strategies in the setting of ischemic brain diseases. Another innovative finding of the present study was the possible neurotrophic/neuroplastic properties of T. catigua.",
"37607495": "ID: 37607495\nTitle: Effect of Leuprolide Acetate, a GnRH Agonist, on Neuroinflammation and Anxiety-Like Behavior after Mild Hypoxic-Ischemic Encephalopathy in Rat Model.\nAbstract: Mild hypoxic-ischemic encephalopathy (HIE) is a condition that predisposes to negative outcomes such as neuroanatomical injury, mood disorders, and motor or cognitive disabilities. The neuroinflammation plays an important role in the neurological damage; therefore, reducing it could provide neuroprotection. The leuprolide acetate (LA) has shown to have neuroregenerative and immunomodulator properties in other nervous system injuries. The aim of this study was to evaluate the immunomodulatory effect of LA in the acute phase of mild HIE and its effects in motor activity and behavior in a subacute phase. Forty-five Wistar rats on postnatal day 7 were divided into Sham, HIE treated with saline solution (HIE-SS), and HIE-LA. The HIE was performed cutting of the right carotid artery followed by 60 min of hypoxia. The expression of the inflammatory cytokines interleukin (IL)-1\u03b2, tumor necrosis factor (TNF)-\u03b1, interferon (IFN)-\u03b3, and the chemokine CXCL-1 were evaluated 72 h after HIE by RT-qPCR and the motor activity and behavior were evaluated by open field test at postnatal day 33. HIE-SS animals showed increased expression of IL-1\u03b2, TNF-\u03b1, IFN-\u03b3, and CXCL-1 genes in injured tissue. However, the HIE-LA group exhibited similar expression levels of IL-1\u03b2 and TNF-\u03b1 to the Sham group, while IFN-\u03b3 and CXCL-1 mRNA expression were attenuated with LA treatment. LA treatment also prevented anxiety-like behavior in the open field test. Treatment with LA partially reverses HIE-induced neuroinflammation and prevents anxiety-like behavior in neonatal rats.",
"37932046": "ID: 37932046\nTitle: Low Glycolysis Is Neuroprotective during Anoxic Spreading Depolarization (SD) and Reoxygenation in Locusts.\nAbstract: Migratory locusts enter a reversible hypometabolic coma to survive environmental anoxia, wherein the cessation of CNS activity is driven by spreading depolarization (SD). While glycolysis is recognized as a crucial anaerobic energy source contributing to animal anoxia tolerance, its influence on the anoxic SD trajectory and recovery outcomes remains poorly understood. We investigated the effects of varying glycolytic capacity on adult female locust anoxic SD parameters, using glucose or the glycolytic inhibitors 2-deoxy-d-glucose (2DG) or monosodium iodoacetate (MIA). Surprisingly, 2DG treatment shared similarities with glucose yet had opposite effects compared with MIA. Specifically, although SD onset was not affected, both glucose and 2DG expedited the recovery of CNS electrical activity during reoxygenation, whereas MIA delayed it. Additionally, glucose and MIA, but not 2DG, increased tissue damage and neural cell death following anoxia-reoxygenation. Notably, glucose-induced injuries were associated with heightened CO2 output during the early phase of reoxygenation. Conversely, 2DG resulted in a bimodal response, initially dampening CO2 output and gradually increasing it throughout the recovery period. Given the discrepancies between effects of 2DG and MIA, the current results require cautious interpretations. Nonetheless, our findings present evidence that glycolysis is not a critical metabolic component in either anoxic SD onset or recovery and that heightened glycolysis during reoxygenation may exacerbate CNS injuries. Furthermore, we suggest that locust anoxic recovery is not solely dependent on energy availability, and the regulation of metabolic flux during early reoxygenation may constitute a strategy to mitigate damage.",

Eighteen individuals were classified as normal weight (NW; n\u00a0=\u00a09 - age: 25\u00a0\u00b1\u00a05 and BMI: 21.4\u00a0\u00b1\u00a01.7) and overweight/obese (OW; n\u00a0=\u00a09 - age: 29\u00a0\u00b1\u00a07 and BMI: 29.2\u00a0\u00b1\u00a02.7). The body composition was evaluated by dual-energy x-ray absorptiometry (DXA), waist circumference, and visceral and subcutaneous fat depots by ultrasound. Physical activity levels, metabolic parameters, immune phenotypic characterization, cytokine production by lipopolysaccharide (LPS) -stimulated whole blood cells and LPS or phorbol 12-myristate 13-acetate (PMA)-stimulated PBMC, and mitochondrial respiration in PBMCs were evaluated. Expression of AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor gamma (PPAR-\u03b3), nuclear factor-kappa B (NF-\u03baB), toll-like receptor 4 (TLR-4), hypoxia-inducible factor-1 alpha (HIF-1\u03b1), and adrenergic receptor beta 1 and 2 (AR-\u03b21 and \u03b22) genes were evaluated in cultured PBMC using quantitative real-time polymerase chain reaction (qRT-PCR). Individuals with overweight/obese (OW) presented higher glucose (P\u00a0=\u00a00.009) and leptin (P\u00a0=\u00a00.010) than individuals with normal weight (NW). PBMCs of OW under stimulation with LPS presented a lower production of interleukin-10 (IL-10) (P\u00a0=\u00a00.011) and macrophage inflammatory protein-1alpha (MIP-1\u03b1) (P\u00a0=\u00a00.048) than NW. Mitochondrial respiration rates were not different between NW and OW subjects. Cultured PBMCs in LPS-stimulated condition indicated higher gene expression of AR-\u03b22 in OW, while PMA-stimulated PBMCs presented lower expression of AMPK (P\u00a0=\u00a00.002) and higher expression of NF-\u03baB (P=<0.0001) than NW. OW presented higher numbers of CD3+CD4+ T cells (P\u00a0=\u00a00.009) and higher expression of programmed cell death protein 1 (PD-1) in CD8+ T cells (P\u00a0=\u00a00.001) than NW.

This therapy involves the use of Myristica fragrans Houtt. and Carum carvi L., along with fomentation and massage, and has shown significant clinical effects. However, the mechanism of how Huoermai therapy treats plateau insomnia needs further clarification. This study aimed to investigate the mechanism of action of Huoermai essential oil (HEO) in treating plateau insomnia, focusing on the cAMP/CREB/BDNF/GABAergic pathway. The major components of Huoermai essential oil were identified by Gas chromatography-mass spectrometry (GC-MS) for subsequent network pharmacology analysis. Proteomics techniques were employed to pinpoint disparities in brain tissue protein expression in a mouse model of plateau insomnia following Huoermai therapy administration, in conjunction with network pharmacology to forecast pathways related to hypoxia and insomnia. Plateau insomnia mouse model was established and the therapeutic impact of Huoermai essential oil was evaluated. Hematoxylin & Eosin staining(HE) was conducted to observe pathological damage to the cortex, hippocampus, thalamus and hypothalamus structures. Changes in serotonin (5-HT), melatonin (MT), adenosine (AD), cyclic adenosine monophosphate (cAMP) and malondialdehyde (MDA) levels in mouse brain tissue were gauged through enzyme-linked immunosorbent assay (ELISA) to assess sleep status and oxidative stress levels in mice. Molecular docking was employed to anticipate the target binding energy of Huoermai essential oil constituents. ELISA and Western Blot (WB) were used to ascertain the expression of cAMP/CREB/BDNF/GABAergic pathway. The results indicated that HEO positively impacted intermittent hypobaric hypoxia-induced plateau insomnia in mice. Histological examination results showed that HEO ameliorated neuronal damage in specific regions of the brain affected by plateau insomnia, such as the cortex, hippocampus, thalamus, and hypothalamus. Through GC-MS analysis, 56 volatile oil components were identified. Subsequently, a combined network pharmacology and proteomics analyses led to selecting the cAMP/CREB/BDNF/GABAergic pathway for further study. ELISA experiments demonstrated that HEO treatment increased GABA and MT levels while significantly reducing 5-HT and adenosine levels in brain tissue of mice with plateau insomnia. WB results revealed that HEO ameliorated plateau insomnia by suppressing the hyperactivation of the cAMP pathway, increasing brain-derived neurotrophic factor (BDNF) levels and B-cell lymphoma-2 (BCL-2) expression, and alleviating hypoxia-induced oxidative stress. Moreover, molecular docking results showed strong binding affinity of all pharmacological components to their targets and proteins in the brain. These results indicate that HEO significantly prolongs sleep duration in plateau insomniac mice and treats plateau insomnia by modulating levels of sleep-related regulators, modulating the cAMP pathway, increasing GABA receptor expression, and improving neuronal survival and anti-apoptosis.",

It was aimed to elucidate the potential therapeutic effect of estrogen receptor agonists on NEC-induced intestinal and brain injury in rats. Sprague-Dawley pups of both sexes were separated from their mothers at postnatal 5th d. Feeding with formula along with a single session of hypoxia was applied to induce NEC, while control pups were kept with their mothers. The NEC rats received either vehicle, estrogen receptor \u03b1 (ER\u03b1) agonist propyl pyrazole triol (1\u00a0mg/kg/day), ER\u03b2 agonist diarylpropionitrile (1\u00a0mg/kg/day), or 17\u03b2-estradiol (1\u00a0mg/kg/day) during maternal separation. All pups were decapitated on postnatal 9th d to collect intestinal and brain tissue samples. Elevation in proinflammatory cytokines, apoptosis, and microscopically and biochemically evident oxidative injury in both the intestinal and brain tissues were observed in NEC-induced pups. In both the intestinal and brain tissues, nerve growth factor and brain-derived neurotrophic factor protein levels were depleted, expressions of both the ESR1 and ESR2 genes were downregulated, while treatment with 17\u03b2-estradiol or ER agonists alleviated extent of oxidative injury of the intestines and brain tissue, upregulated nerve growth factor, brain-derived neurotrophic factor, and ER gene expressions, abolished NEC-induced decrease in claudin-3 expression, increased the survival rates, improved the clinical states of the survived pups at varying degrees. Activation of estrogen signaling by receptor agonists alleviated NEC-induced intestinal and cerebral injury, implicating that estrogen agonists could be regarded as promising preventive/therapeutic agents for NEC.",

This study aimed to examine the changes in microbiota metabolites, brain-derived neurotrophic factors and synaptic proteins in insomnia patients, with a particular focus on the impact of diet. A total of 41 patients with insomnia and 45 healthy individuals participated in the study. The Food Frequency Questionnaire was employed to ascertain the subjects' daily macronutrient intake over the previous month. Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to evaluate insomnia complaints. The concentration of faecal short-chain fatty acids (SCFAs) was quantified by gas chromatography. Serum zonulin, brain derived neurotrophic factor (BDNF), postsynaptic density protein 95 (PSD-95) and synaptophysin-like protein 1 (SYPL1) protein levels were quantified using an enzyme-linked immunosorbent assay (ELISA) method. The total SCFAs, acetic acid, propionic acid, butyric acid and valeric acid levels were found to be significantly lower in the insomnia patient group compared to the control group. The levels of zonulin, PSD-95 and SYPL1 were found to be significantly elevated in the insomnia patient group in comparison to the control group. A significant negative correlation was observed between PSQI and ISI values and fatty acids. It has been demonstrated that sleep deprivation may be associated with alterations in the metabolites produced by the gut microbiota. In Western countries where dietary fibre consumption is low, increasing SCFA levels, promoting gut integrity and homeostasis may be regarded as a promising new approach for the treatment of diseases such as insomnia.",

Children with bronchopneumonia accompanied by wheezing are vulnerable to hypoxia, which may damage other systems. Therefore, this study explored the influence of montelukast combined with methylprednisolone on liver function, platelet count, eosinophil count, and myocardial enzymes in children with bronchopneumonia accompanied by wheezing. Methods The clinical data of this retrospective study included 82 pediatric cases diagnosed with bronchopneumonia and wheezing between April 2022 and April 2024. Based on treatment methods, patients were divided into the methylprednisolone group (40 cases) as well as the montelukast and methylprednisolone group (42 cases). Therapeutic efficacy, resolution time of clinical symptoms, and adverse effects were recorded. Furthermore, liver function indicators, platelet count, eosinophil count, and myocardial enzyme levels were comparatively assessed using biochemical analyzer, hematology analyzer and biological kits in both groups. Results The total efficacy rate of the montelukast and methylprednisolone group was 95.2% (40/42), higher than the 77.5% of the methylprednisolone group (p = 0.018). Patients in the montelukast and methylprednisolone group had shorter hospitalization and clinical symptom disappearance times than the methylprednisolone group (both p < 0.05). In addition, there was no significant difference in total incidence of adverse reactions (p = 0.700). Methylprednisolone monotherapy or in combination with montelukast, substantially reduced liver function indicators, platelet count, eosinophil count, and myocardial enzyme levels (p < 0.05). Moreover, the platelet count, eosinophil count, and myocardial enzymes [aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and creatine kinase isoenzyme (CK-MB)] were reduced in the montelukast and methylprednisolone group compared to the methylprednisolone group after treatment (p < 0.05). Compared to the methylprednisolone group, alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBIL), direct bilirubin (DBIL) levels were significantly diminished in the montelukast and methylprednisolone group following treatment (p < 0.05). Conclusion Montelukast and methylprednisolone combination therapy reduces platelet and eosinophil counts, alleviates myocardial and liver function damage, and demonstrates good therapeutic efficacy in children with bronchopneumonia accompanied by wheezing.",

Whole-genome analysis confirmed the absence of virulence factors, plasmids, and antibiotic-resistance genes. Metabolomic profiling of cell-free supernatants (CFSs) and extracellular vesicle (EV) postbiotics revealed a high- and medium-dependent production of neuroactive metabolites, including \u03b3-aminobutyric acid, tryptophan, tyrosine, and tyramine, as well as physiologically relevant levels of short-chain fatty acids, such as acetate, propionate, and butyrate. Functionally, CFS enhanced epithelial barrier integrity by increasing transepithelial electrical resistance and mitigating LPS-induced disruption in Caco2/HT29 monolayers without cytotoxic effects. Both CFS and EVs exhibited immunomodulatory properties, characterized by elevated Il-10/Tnf-\u03b1 ratios under basal conditions and significant suppression of Tnf-\u03b1 expression in LPS-stimulated RAW 264.7 macrophages. Notably, CFS and EVs increased tryptophan hydroxylase 1 (Tph1) gene expression in enterochromaffin RIN14B cells by 6.6- and 3.2-fold, respectively, suggesting enhanced serotonergic activity. These findings highlight B. finegoldii UO.H1052 as a promising next-generation psychobiotic candidate with neuroactive, barrier-protective, and immunoregulatory properties, supporting its potential for gut-brain axis modulation. Emerging evidence supports the critical role of the gut microbiota in modulating host neurophysiology and immune function via the gut-brain axis. Here, we present a comprehensive characterization of Bacteroides finegoldii UO.H1052, a human gut commensal that exhibits promising psychobiotic attributes, including the production of neuroactive compounds and extracellular vesicles (EVs) with immunoregulatory and serotonin-inducing properties. The strain exhibits a favorable safety profile, with no detected virulence factors or transmissible antibiotic resistance. Importantly, cell-free supernatants and EVs enhanced epithelial barrier integrity, modulated pro- and anti-inflammatory cytokine responses, and significantly upregulated the expression of Tph1, a key enzyme in serotonin biosynthesis. These findings underscore the potential of B. finegoldii UO.H1052 as a next-generation psychobiotic candidate and highlight EVs as effective postbiotic mediators of host-microbe communication. This study advances the understanding of Bacteroides-derived psychobiotics and provides a foundation for their development in modulating gut-brain and immune pathways relevant to neuroinflammatory and gastrointestinal disorders.",
"40961414": "ID: 40961414\nTitle: Short-Chain Fatty Acid Supplementation After Traumatic Brain Injury Attenuates Neurologic Injury Via the Gut-Brain-Microglia Axis.\nAbstract: Traumatic brain injury (TBI) is an underrecognized public health threat. There are limited therapeutic options for TBI, and supportive care remains the mainstay of treatment. Our previously published data demonstrate that post-TBI fecal microbiome transplantation (FMT) can reverse TBI-induced depletion of commensal bacteria, preserve white matter connectivity and neurocognition, and decrease cortical volume loss in mice after TBI. We hypothesized that post-TBI supplementation with short-chain fatty acids (SCFAs), metabolites of commensal gut bacteria, would attenuate neurologic injury after TBI in mice. 14-week-old male C57BL/6 mice ( n = 52) underwent TBI via a controlled cortical impact versus sham injury. Post-TBI, each group was treated with the SCFAs acetate, butyrate, and propionate versus a molar-equivalent sodium chloride vehicle via free access to drinking water for 4 weeks post-TBI. The stool was collected 3 days pre- and 60 days post-TBI to assess the gut microbial community structure via 16s ribosomal RNA gene amplicon sequencing. Neurocognitive testing was performed with open-field and zero-maze testing. Ventricular volume and white matter connectivity were measured with 3D, contrast-enhanced magnetic resonance imaging. Lastly, the transcriptional response of microglia was assessed with single-cell RNA sequencing (scRNAseq). SCFA supplementation decreased TBI-induced microbial loss, attenuated ventricular volume loss, preserved white matter connectivity, and altered the transcriptional profile of microglia after TBI. Post-TBI SCFA supplementation preserved the abundance of the butyrate-producing taxa Firmicutes, Clostridia, Ruminoccacaceae , and Peptoccacaceae ( P\u2009=\u2009 0.01). SCFA also reduced the TBI-induced increase in Clostridiales and Bacteroidales compared with the salt vehicle group ( P\u2009=\u2009 0.05). We also observed the preservation of non-TBI murine anxiety-like behavior in SCFA-treated TBI mice compared with vehicle-treated TBI mice in the zero-maze (152.3 \u2009 \u00b1 \u2009 101.8\u2009cm vs. 147.5 \u2009 \u00b1 \u2009 60.0\u2009cm, P\u2009=\u2009 0.006). These results were recapitulated with open-field testing (11.7 \u2009 \u00b1 \u2009 3%-time in the center in SCFA-treated TBI mice vs. 15.0 \u2009 \u00b1 \u2009 6%-time in the center of the field in vehicle-treated mice; P\u2009=\u2009 0.002). Lastly, we observed upregulation of transcripts for the neuroprotective heat-shock family of proteins and downregulation of neurodegeneration-associated transcripts, indicating an overall neuroprotective phenotype in microglia after SCFA supplementation post-TBI. We hypothesized that SCFA supplementation would attenuate neurologic injury after TBI in mice. SCFA supplementation attenuated neurocognitive deficits, reduced cortical volume loss, preserved white matter connectivity, and decreased neuroinflammation. These benefits may result from the direct replacement of SCFAs. However, there may also be secondary mechanisms related to commensal refeeding of butyrate-producing bacteria within the gut microbial community, a neuroprotective heat-shock response, and a decrease in the expression of genes associated with neurodegeneration. The current study highlights the role of SCFAs in microbiome homeostasis and the potential of dietary intervention as a novel therapy in TBI.",

It is known that the microbiota-gut-brain-axis plays a role in the pathogenesis, but the pathways are not fully understood yet. To elucidate the role of dietary fibre supplementation on this axis in a 5xFAD mouse model of Alzheimer\u00b4s disease, a feeding trial with an inulin supplement was conducted. At the start (Basis, n\u2009=\u200911) and after 7 weeks with (AD\u2009+\u2009F; n\u2009=\u200915) and without (AD; n\u2009=\u200915) supplementation, the mice were sacrificed and the following samples were taken: ingesta for 16\u00a0S rRNA sequencing and short-chain fatty acid (SCFA) analysis, and brain tissue for amyloid-beta staining and proteome analysis. The microbiota patterns in stomach, small intestine, caecum and colon differed between AD and AD\u2009+\u2009F. SCFA concentrations were significantly higher in group AD\u2009+\u2009F as compared to AD and Basis. In the AD mice, plaque load was significantly increased as compared to Basis, while a reduction in AD\u2009+\u2009F as compared to AD was observed. The brain proteome also differed between AD\u2009+\u2009F and AD, indicating a beneficial effect of the inulin supplementation, possibly mediated in part by microbial acetate. Since prebiotic substances like inulin are also part of human diets, this should be investigated further in the translational context.",

Flavonoids and other natural compounds possessing antioxidant and neuroprotective properties can be of therapeutic interest. In the current study, naringin's protective property as a flavonoid was compared with that of N-acetylcysteine (NAC) against lead-induced neurotoxicity in rats. Adult rats were randomly distributed into control, lead acetate-treated, lead+NAC-treated, lead+low-dose naringin, and lead+high-dose naringin groups, each group containing 6 animals. The Novel Object Recognition (NOR) test was used for the evaluation of cognitive function. Biochemical analysis of hippocampal glutamate, acetylcholine, Brain-Derived Neurotrophic Factor (BDNF), Nuclear factor erythroid 2-related factor 2 (Nrf2), pro-inflammatory markers (IL-6, GFAP), and serum lead levels was done. Histopathological analysis of hippocampal sections by crystal violet staining was done. Exposure to lead acetate-induced severe neurotoxicity in the guise of compromised recognition memory, reduced glutamate and acetylcholine content, reduced BDNF and Nrf2 expression, increased IL-6 and GFAP content, and severe hippocampal neuronal damage. NAC treatment effectively reversed cognitive function, neurotransmitter content, neurotrophic factors, and diminished neuroinflammation. Dose-dependent neuroprotection was afforded by naringin, where the high-dose group had better recovery in all the parameters than the low-dose group. Interestingly, high-dose naringin was similar to or even larger than that of NAC's neuroprotection, normalization of hippocampal histoarchitecture, enhancement of antioxidant defense, and decrease in pro-inflammatory markers and serum lead levels. Lead acetate causes profound neurotoxicity on cognition, neurotransmission, oxidative stress, and inflammation. Naringin, especially at high doses, exhibits highly potent neuroprotective effects, such as NAC, preventing lead-induced cognitive dysfunction and hippocampal pathology by displaying antioxidant, anti-inflammatory, and neurotrophic effects. The results propose naringin as a potential natural drug candidate for preventing and/or treating lead-induced neurotoxicity.",
"41080555": "ID: 41080555\nTitle: A high-calorie diet exacerbates lipopolysaccharide-induced pneumonia by promoting acetate-mediated macrophage polarization via the HDAC9/10-HIF-1\u03b1-glycolysis axis.\nAbstract: Lung macrophage polarization imbalance is an important cause of aggravated pulmonary inflammation. The gut microbiota metabolites short-chain fatty acids (SCFAs) are an important regulator of macrophage polarization. A high-calorie diet has been shown to aggravate pneumonia and delay recovery, especially in children. However, the underlying mechanisms remain unclear. Our previous studies showed that a high-calorie diet can disrupt the gut microbiota structure and SCFA metabolism to aggravate LPS-induced lung inflammatory damage in juvenile rats. In this study, we investigated whether pneumonia aggravated owing to a high-calorie diet is associated with SCFA-driven macrophage phenotype changes in distal lung tissues and related mechanisms. Our data revealed that a high-calorie diet significantly aggravated pulmonary inflammatory injury in juvenile mice with LPS-induced pneumonia and also increased lung tissue M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization imbalance. We found that a high-calorie diet decreased SCFA levels in mouse stool, serum, and lung tissues, which was most pronounced for acetate. Furthermore, we found that acetate reduction mediated by a high-calorie diet exacerbated M1-like (CD206\u207bCD86\u207a)/M2-like (CD206\u207aCD86\u207b) macrophage polarization imbalance in the lung tissue of pneumonia model mice and was associated with inhibiting histone deacetylase (HDAC), rather than G-protein-coupled receptor 43 (GPR43) signaling. More critically, we found that acetate supplementation had the most significant impact on HDAC9 and HDAC10 in the lung macrophages of pneumonia model mice fed a high-calorie diet. Furthermore, overexpression of Hdac9 and Hdac10 significantly attenuated the improvement effects of acetate on lung tissue M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization in pneumonia model mice fed a high-calorie diet, and this mechanism was associated with the HIF-1\u03b1-glycolysis axis. Taken together, we demonstrated that a high-calorie diet could cause acetate levels to decrease in mice with LPS-induced pneumonia. This decrease in acetate was associated with a diminished inhibitory effect on HDAC9/10, potentially contributing to upregulation of HIF-1\u03b1 expression and increased glycolysis. These changes may be linked to an imbalance in M1-like (CD206-CD86+)/M2-like (CD206+CD86-) macrophage polarization and aggravate lung tissue inflammatory injury. Our findings show that acetate supplementation may be a potential treatment strategy to prevent and treat pneumonia and other infectious diseases.",
"41102470": "ID: 41102470\nTitle: Closing the gap before using L-lactate to guide newborn care.\nAbstract: We thank the authors for their insightful commentary on our study investigating sodium L-lactate (NaL) supplementation in preterm infants with metabolic acidosis. Their analysis highlights lactate's expanding role beyond a metabolic byproduct, emphasizing its functions in cellular signaling, antioxidant defense, and neuroprotection. Our study demonstrated that NaL improved acid-base balance without adverse effects, likely through lactate's conversion to bicarbonate and potential support for mitochondrial function. The commentary further explores NaL's translational relevance in neonatal hypoxia-ischemia (NHI), where lactate may serve as a key neuroenergetic substrate and modulate inflammation and gene expression. While the Rice-Vannucci model has limitations, it remains valuable for long-term studies, as shown in our prior work. We agree that larger animal models offer enhanced physiological relevance but face practical constraints. Future research should compare NaL with sodium acetate (NaA), a standard in neonatal care, to assess relative benefits in correcting acidosis and supporting neurodevelopment. We support the call for randomized, multicenter studies with long-term follow-up to fully evaluate NaL's therapeutic potential in preterm and at-risk neonates. IMPACT: L-lactate is a key component of the astrocyte-neuron lactate shuttle, supporting brain energy metabolism. Ibrahim et al. suggest sodium L-lactate as an alternative maintenance fluid for preterm newborns. L-lactate should not be regarded merely as a simple fluid replacement. L-lactate acts as a signaling molecule, impacting cellular metabolism and brain development. Additional research is required to assess the potential benefits and safety of sodium L-lactate in newborns.",
"41123675": "ID: 41123675\nTitle: Short-Chain Fatty Acids as a Therapeutic Strategy in Parkinson's Disease: Implications for Neurodegeneration.\nAbstract: Neurodegeneration involves the progressive deterioration of neuronal structure and function, leading to deficits in cognition, motor skills, and other neurological processes. Parkinson's disease (PD) is notably prevalent among neurodegenerative disorders, characterized by dopaminergic neurodegeneration, protein misfolding, and an inflammatory brain environment. Despite advancements in understanding its pathophysiology, PD and other neurodegenerative conditions still lack effective disease-modifying therapies. This shortfall highlights the need for novel, multifactorial approaches to treatment. Recent research has spotlighted the gut-brain axis as a significant player in neurological health, particularly through the activity of gut-derived short-chain fatty acids (SCFAs). These microbial metabolites, primarily acetate, propionate, and butyrate, are produced via the fermentation of dietary fibers and are vital for maintaining intestinal and neural homeostasis. SCFAs exert anti-inflammatory effects, preserve blood-brain barrier integrity, and modulate neurotransmitter systems. Among them, butyrate shows notable neuroprotective capabilities, including histone deacetylase inhibition and mitochondrial enhancement. Disruption in SCFA production has been associated with PD progression, further underscoring their relevance. This review explores the mechanistic roles of SCFAs in modulating neurodegeneration, with an emphasis on PD. SCFA-based strategies offer a promising adjunctive route to restoring microbial balance, mitigating neuroinflammation, and safeguarding neurological function in neurodegenerative disorders.",

Our previous study has revealed that dimeric proanthocyanidins (PACs) mainly existed in the ethyl acetate extract from the roots of Ephedra sinica Stapf (ERE), however, its therapeutic effects on SU5416/hypoxia-induced pulmonary hypertension (PH) rats remain elusive. In this study, column chromatography combined with UPLC-LTQ-Orbitrap-HRMS analysis was performed to comprehensively characterize polyphenols in ERE. The therapeutic effects of ERE were investigated using the SU5416/hypoxia rat model, in which the rats were injected with SU5416 (20 mg/kg), followed by a three-week hypoxia exposure (10% O2). Hemodynamic indicators determined by right heart catheterization, pulmonary arterial morphological changes assessed by histopathological analysis, cardiac function and pulmonary hemodynamics using echocardiography, as well as oxidative stress markers measured by corresponding kits were used to test the therapeutic effects of ERE. Moreover, 16S rRNA sequencing combined with untargeted metabolomics was employed to capture changes in gut microbiota and serum metabolites after ERE treatment. Comprehensive chemical analysis of polyphenols in ERE revealed various levels of proanthocyanidin monomers, dimers and trimers, especially A-type dimers. In vivo experiments showed that ERE decreased pulmonary arterial pressure, right ventricular hypertrophy, right ventricular free wall (RVFW) thickness and oxidative stress levels, increased pulmonary acceleration time (PAT) and alleviated pulmonary vascular remodeling in rats exposed to SU5416/hypoxia treatment. Meanwhile, ERE improved gut microbial dysbiosis and the disturbed glycerophospholipid metabolism. Collectively, this study presents the first report on the efficacy of A-type PACs from Ephedra sinica for the treatment of PH through regulating gut microbiota and host metabolism.",

However, studies assessed its impact on cognitive performance at environmentally unrealistic doses. Nevertheless, the exact mechanism underlying the neurobehavioral phenotype, linking the role of gut microbiota is poorly understood. Here, we evaluated the effects of environmentally plausible dose of BPA-exposure on cognitive task performances with the functional analysis of gut metagenome to elucidate the role of microflora-gut-brain axis in behavioural regulation. Swiss albino mice were exposed to BPA for 5 weeks assessed for working and spatial navigation task performances. qRT-PCR based gene expression, histological investigation, gut permeability, molecular and biochemical markers of neuro-inflammation, leaky gut, oxido-nitrosative stress and 16\u202fs rRNA gene based metagenomics with functional analysis were performed. BPA exposure altered the cognitive task performances (mean difference for transfer latency in elevated plus maze 20.84\u202f\u00b1\u202f5.64\u202fsec in and -13.12\u202f\u00b1\u202f3.53 in Morris' water maze), changed serotonin levels (-70.95\u202f\u00b1\u202f21.43) and acetylcholinesterase activity (0.0032\u202f\u00b1\u202f0.0008), enhanced ileal permeability (12.36\u202f\u00b1\u202f3.56) and systemic and tissue level inflammation (increased brain LPS, TNF-a, IL-1b, IL-6 and circulating TNF-a and IL-1b), coupled with reduced SCFAs levels (acetate; 32.48\u202f\u00b1\u202f8.48, and butyrate; 28.16\u202f\u00b1\u202f9.86).

"41192697": "ID: 41192697\nTitle: Gut microbiome-derived tryptophan metabolites predict relapse in alcohol use disorder.\nAbstract: Relapse is common in alcohol use disorder (AUD), a condition that affects nearly 11\u00a0% of adults in the US. Excessive alcohol consumption causes gut dysbiosis, which may in turn alter the production of bacterial-derived tryptophan metabolites. These metabolites impact the intestinal enteroendocrine environment and modulate neuroinflammation. This can ultimately affect behavior. However, the role of bacterial-derived tryptophan metabolites in AUD is not well-understood. Thus, in this study, we enrolled 40 patients admitted for severe AUD (26 males, 14 females) to investigate whether bacterial-derived indoles could predict AUD relapse. Upon enrollment, alcohol use as well as depression and anxiety symptoms were assessed. Peripheral blood samples were collected and analyzed for cytokines, bacterial-derived as well as endogenous tryptophan metabolites, and hematological factors. At three months after discharge, 25 patients completed follow-up and were re-assessed for clinical symptoms to identify AUD relapse. Ten patients relapsed and 15 patients were in early remission. Two bacterial tryptophan metabolites, indole-3-carboxaldehyde (IAld) and indole-3-acetic acid (IAA), significantly predicted relapse versus remission using logistic regression models (p\u00a0=\u00a00.019, SGPV\u00a0=\u00a00, and p\u00a0=\u00a00.035, SGPV\u00a0=\u00a00 respectively). These findings remained significant after adjustment for age, sex, BMI, and when additionally adjusting for nicotine use and depression severity. Moreover, higher IAld levels correlated with increased serotonin levels (Pearson's R; 0.592, p\u00a0<\u00a00.001) and fewer white blood cells (Pearson's R; -0.318, p\u00a0<\u00a00.05) in all 40 patients. Our data indicate significant interactions between microbiome-derived metabolites and host metabolism, and that IAld specifically may have a protective role in AUD, potentially through serotonin modulation.",
"41254951": "ID: 41254951\nTitle: The probiotic Limosilactobacillus fermentum CECT5716 enhances the antihypertensive response to hydrochlorothiazide in spontaneously hypertensive rats.\nAbstract: Limosilactobacillus fermentum CECT5716 (LC40) consumption reduces hypertension and improves endothelial dysfunction in spontaneously hypertensive rats (SHRs). The diuretic hydrochlorothiazide (HCTZ) lowers blood pressure in SHR but disrupts the gut microbiota balance. In this study, we investigated whether the LC40 could enhance the antihypertensive effects of HCTZ. Interestingly, we found that coadministration of LC40 with HCTZ potentiated the beneficial effects of HCTZ on endothelial dysfunction and blood pressure without altering plasma HCTZ concentrations or exacerbating electrolyte imbalances. These protective effects were associated with normalization of microbiota alterations, including a reduction in the Firmicutes/Bacteroidota ratio, suppression of lipopolysaccharide biosynthesis, and an increase in acetate-producing bacteria. Additionally, LC40 reduced intestinal pathology and endotoxemia. Furthermore, the HCTZ\u2009+\u2009LC40-treated rats exhibited reduced neuroinflammation and sympathetic activity, along with an immunoregulatory effect characterized by increased regulatory T cell infiltration and a reduction of vascular oxidative stress in the aorta. The beneficial effects of LC40 in HCTZ-treated rats appeared to be microbiota dependent, as they were replicated through fecal microbiota transplantation in germ-depleted normotensive rats. Our findings identify the gut microbiota as a novel therapeutic target to enhance the antihypertensive effects of diuretics. The coadministration of LC40 with HCTZ modulates immune responses, providing a promising strategy to improve hypertension management.",

Currently, there are no effective treatments or preventive measures for these disorders. This study evaluated the therapeutic potential of short-chain fatty acids (SCFAs) and probiotics on PrDs using hamsters intracerebrally inoculated with the 263K scrapie strain. Treatments included oral administration of SCFAs (sodium propionate, butyrate, acetate) and probiotics (Clostridium butyricum, Bifidobacterium infantis). Clinical symptoms were monitored, and samples from brains, feces, and sera were collected at various time points for analysis. Assessments covered PrPSc deposits, gliosis, neuroinflammation, SCFA-related elements, gut microbiota profiles via 16S rRNA sequencing, and fatty acid levels measured by LC-MS/MS. Although all infected animals eventually died, those treated with SCFAs and probiotics showed a significant delay in clinical symptom onset and extended disease course. There was a notable reduction in the progression of PrPSc deposits, gliosis, and neuroinflammation in treated groups. Additionally, the decrease in SCFA receptors GPR41 and MCT4, along with downstream proteins Nrf2 and HO-1 in the brain, was slowed. Gut microbiota analysis revealed more beneficial bacteria in the SCFA and probiotic groups compared to controls. However, no significant differences were observed in serum and fecal fatty acid levels among groups. Oral administration of SCFAs and probiotics post-prion infection can effectively delay disease onset and progression while mitigating neuropathological changes associated with prion diseases. These results suggest a promising, cost-effective dietary intervention strategy for managing PrDs clinically.",

Clinical observations have shown that Liqi Yangyin (LQYY) can effectively relieve symptoms of depression accompanied by constipation. However, whether LQYY exerts its effects through gut-brain crosstalk remains to be elucidated. A chronic unpredictable mild stress (CUMS) protocol was employed to establish a mouse model. H&E and Nissl staining were used to examine pathological changes in the prefrontal cortex (PFC) and colon. The ultrastructure of the intestinal barrier was observed via transmission electron microscopy, while the expression of the blood-brain barrier tight junction proteins was quantified by Western blotting (WB). ELISA quantified inflammatory factors and serotonin (5-HT) levels. Immunohistochemistry, immunofluorescence, and WB analyzed IBA-1 and Free fatty acid receptor 2 (FFAR2) expression levels. Gut microbiota composition was analyzed via 16S rDNA sequencing, and SCFAs levels were quantified using UHPLC-TSQ Altis Plus. Additionally, in vitro studies using BV-2 cells involved treatments with acetic acid (ACE) and an FFAR2 antagonist, after which the expression of relevant indicators was assessed. Our results demonstrated that LQYY significantly ameliorated CUMS-induced behavioral changes and improved intestinal motility. These effects were associated with the restoration of gut microbiota balance and an increase in ACE levels. LQYY increased FFAR2 expression, leading to reduced neuroinflammation and enhanced colonic 5-HT secretion. Furthermore, LQYY protected intestinal and blood-brain barrier integrity and improved neuronal morphology in the PFC. In vitro studies confirmed that ACE suppresses microglial inflammation through upregulating FFAR2 expression, an effect that was attenuated by the FFAR2 inhibitor GLPG0974. These findings suggest that LQYY modulates the gut-brain axis through ACE/FFAR2, offering a promising therapeutic approach for depression and constipation.",

Metabolites produced by the gut microbiota, particularly short-chain fatty acids (SCFAs), act as key mediators in this bidirectional communication. While the roles of acetate, propionate, and butyrate are well-established, valeric acid (VA), a five-carbon SCFA, is poorly understood. This comprehensive review explores VA as a gut-derived physiological epigenetic modulator, examining its microbial biosynthesis and systemic effects. This review discusses how VA acts as a selective histone deacetylase inhibitor (HDACi), particularly targeting Class I HDACs, to modulate gene expression and exert neuroprotective and anti-inflammatory effects. The analysis compares VA with its pharmacological analog, valproic acid (VPA), a well-known but non-selective HDACi. This comparison highlights how VA's physiological nature may offer a more targeted and safer intervention. In conclusion, elucidating VA's role as a microbiome-derived epigenetic regulator would open promising avenues for therapeutic strategies that directly connect gut and CNS health within the GBA.",
"41314293": "ID: 41314293\nTitle: Caloric Restriction Alleviates Anxiety-Like Behaviors by Mitigating Neuroinflammation and Insulin Signaling Dysregulation in a High-Fat Diet-Induced Obesity Mouse Model.\nAbstract: Caloric restriction (CR) is reported to promote longevity and improve metabolism in different species, such as rodents and flies. However, limited studies have examined the effects of CR on obesity-associated psychiatric disorders and the underlying mechanisms. This study aimed to investigate the effects of CR on obesity-associated anxiety-like behavior in mice fed on a high-fat diet (HFD) and elucidate the underlying mechanisms. Male C57BL/6 mice (n = 24) were randomized into the standard diet group and the HFD group (fed on an HFD for 8 wk to induce obesity). The mice in the HFD group (n = 16) were further randomized into the following 2 groups for an additional 4-wk dietary intervention: the HFD group and calorie-restricted HFD (HFCR) group (received 70% of the mean daily food intake in the previous 3 d). Mouse body weight, anxiety-like behaviors, peripheral insulin sensitivity, central insulin signaling, and fecal microbiota were assessed. HFCR effectively mitigated HFD-induced weight gain and insulin resistance, demonstrating significant reductions in final body weight (-28.0%), glucose area under the curve (-30.7%), and homeostasis model assessment of insulin resistance index (-58.8%) compared with the HFD group (P < 0.01). HFCR also significantly reduced anxiety-like behaviors in open-field and elevated plus maze tests (P < 0.05). Mechanistically, HFCR suppressed neuroinflammatory pathways by inhibiting NF-\u03baB activation and c-Jun N-terminal kinase phosphorylation, while concurrently improving central insulin sensitivity via the insulin receptor substrate 1/Akt pathway (P < 0.05). Furthermore, HFCR remodeled the gut microbiota profile and markedly increased fecal short-chain fatty acid concentrations, with acetic acid and propionic acid levels rising by 107.7% and 57.0%, respectively (P < 0.01). In summary, our data indicate that CR, even without a change in dietary composition, could attenuate HFD-induced anxiety symptoms by modulating the gut microbiota, suppressing neuroinflammation, and regulating the brain insulin signaling pathway in adult male obese mice.",
"41317578": "ID: 41317578\nTitle: Bilobalide isolated from Ginkgo leaf tea alleviates Parkinson's disease via suppressing neuroinflammation and remodeling gut microbiota.\nAbstract: Parkinson's disease (PD) is a prevalent neurodegenerative disorder with limited effective treatments. Ginkgo leaf tea (GLT), derived from the dried leaves of Ginkgo biloba, has long been consumed for its cardiovascular and neurological health benefits. However, the neuroprotective compounds in GLT and their mechanisms of action in PD remain largely unexplored. This study aimed to isolate neuroprotective constituents from GLT and investigate their therapeutic potential and underlying mechanisms in the context of PD. Neuroactive compounds were identified through bioactivity-guided fractionation and GNPS molecular networking. The effects of the principal component, bilobalide (BB), were evaluated in MPTP-induced PD mice using behavioral assessments, immunohistochemistry, and histopathological analysis. Mechanistic studies integrated network pharmacology with transcriptomic profiling. The gut microbiota composition and short-chain fatty acids (SCFAs) were analyzed to explore the modulation of the gut-brain axis. Ten compounds, including four terpenes, five flavonoids, and one phenol, were isolated from GLT, all showing prophylactic efficacy against PD. Notably, the sesquiterpenoid BB, identified as the key therapeutic component via activity-labeled molecular networking, significantly alleviated MPTP-induced motor deficits and dopaminergic neuronal loss in a dose-dependent manner. Transcriptomic and network analyses revealed that BB mitigated neuroinflammation by modulating the cAMP-PKA-CREB and TLR4/NLRP3 signaling pathways. Additionally, BB reshaped the gut microbiota by enriching beneficial taxa (e.g., Lachnospiraceae) and reducing pathogenic species (e.g., Helicobacter), accompanied by increased levels of acetate and butyrate. BB, the predominant active compound in GLT, exerts neuroprotective effects in PD through the dual mechanisms of suppressing neuroinflammatory signaling and restoring gut-brain axis homeostasis. These findings position GLT as a promising dietary source of bioactive compounds with therapeutic potential for neurodegenerative diseases.",

Here, L-theanine alleviated reserpine-induced depression-like behaviors in rats, improving anhedonia, despair, and cognitive deficits, while reducing serum IL-1\u03b2, IL-6, and TNF-\u03b1, restoring hippocampal BDNF, and mitigating neuronal damage. Multi-tissue non-targeted metabolomics (serum, brain, colon, feces) revealed that L-theanine reversed phospholipid and bile acid disturbances and restored key neuroprotective metabolites. Targeted metabolomics validated the non-targeted findings by confirming that L-theanine alleviated bile acid dysregulation and restored SCFA profiles. Additionally, L-theanine modulated gut microbiota composition, increasing beneficial genera such as Alloprevotella and Prevotellaceae_UCG-001, while reducing potentially harmful taxa. Correlation analyses indicated that these microbiota changes were linked to bile acid and SCFA profiles, suggesting gut-brain axis involvement. Overall, L-theanine exerts antidepressant effects by modulating neuroinflammation, neuroplasticity, and metabolism, highlighting its potential as a functional food for depression.",

However, the link between SCFA depletion and long-term neurologic impairment (LTNI) after TBI remains unclear. Previously, we and others noted the involvement of metabolite-sensing receptors and SCFA ligands in mouse models of neurodegenerative diseases, including Alzheimer's. Here, we further investigated SCFA-mediated neuroprotection in LTNI at both microbiome and single-cell resolution using the controlled cortical impact (CCI) model of TBI with a high-yielding SCFA diet to examine their mechanistic role in pathogenesis. C57BL6/J mice were randomized to CCI (6\u00a0m/s, 2\u00a0mm) or sham surgery. Following surgery, mice were randomized to a study diet based on a balanced modification of the AIN93-G diet containing either 15% high amylose maize starch (HAMS) control diet or acetylated and butyrylated HAMS (HAMSAB) for 6 months to model increased SCFA production by bacterial fermentation in the gut. Morris water maze test and nesting assessment were performed at 1, 3, and 6 months after injury. The longitudinal gut microbiome changes were investigated by 16\u00a0S rRNA amplicon and metagenomic sequencing of fecal pellets at baseline, 1 month, and 6 months post-injury. At 6 months, pericontusional tissue was collected for single-cell RNA-sequencing following the 10X Genomics protocol or histologic analysis. Compared to the HAMS control diet, HAMSAB diet remodeled the CCI murine gut microbiome at an early phase, increased various SCFA-producing taxa, and attenuated neurologic deficits up to 6 months after CCI. In mice fed HAMSAB diet, single-cell transcriptomics and pathway analysis identified the promotion of neurogenesis, including increased doublecortin-positive immature neurons. In myeloid cells, HAMSAB induced an anti-inflammatory phenotype, inhibiting pro-inflammatory signaling interaction such as midkine signaling, and promoted differentiation to disease-associated microglia (DAM). Simultaneously, SCFAs reduced neurodegenerative pathway activity in neurons and glial cells and reduced phosphorylated tau deposition in pericontusional cortex. Diet-facilitated microbial production of acetate and butyrate attenuates behavioral deficits of LTNI after TBI and produces enduring benefits at the single-cell level on the neuro-inflammatory and neuro-progenitor responses. This therapeutic approach could have a broader potential to prevent neurodegenerative disease.",

This case-control study included 80 subjects, comprising 40 patients with CFS and 40 age- and sex-matched HC. Fecal microbial community structure was analyzed using 16S rRNA gene high-throughput sequencing. Fecal SCFAs concentrations were quantified using Gas Chromatography-Mass Spectrometry (GC-MS). Spearman correlation analysis with false discovery rate (FDR) adjustment was performed to elucidate associations among gut microbiota, SCFAs, and clinical scores. Compared to the HC group, the CFS group exhibited reduced gut microbiota \u03b1-diversity (e.g., ACE, Chao1, Shannon indices, all P\u2009<\u20090.01) and significantly altered \u03b2-diversity (ADONIS, P\u2009=\u20090.006). After FDR adjustment, fecal levels of acetate, butyrate, isobutyrate, and isovalerate remained significantly lower in the CFS group (all q\u2009<\u20090.05). Differential abundance analysis revealed a significant reduction in key taxa including the phylum Firmicutes (q\u2009=\u20090.010), class Verrucomicrobiae (q\u2009=\u20090.038), order Clostridiales (q\u2009=\u20090.043), and families Rikenellaceae (q\u2009=\u20090.011) and Ruminococcaceae (q\u2009=\u20090.049). Spearman correlation analysis solidified functional connections: key SCFA-producing taxa (e.g., Faecalibacterium, Subdoligranulum, Ruminococcaceae) were positively correlated with butyrate levels (r\u2009=\u20090.52-0.56, all q\u2009<\u20090.05). Furthermore, reduced abundances of Rikenellaceae and Alistipes were associated with lower SF-36 scores (r\u2009=\u20090.26, q\u2009=\u20090.032) and higher fatigue scores (FSS/FS-14, r\u2009=\u2009\u2009-\u20090.28 to\u2009-\u20090.30, q\u2009<\u20090.05). Isovalerate levels were negatively correlated with FS-14 scores (r\u2009=\u2009\u2009-\u20090.307, q\u2009=\u20090.014). Among CFS patients, those with higher dietary fiber intake had significantly higher levels of acetate and isovalerate than those with lower intake (both q\u2009<\u20090.05). Patients with CFS exhibit significant gut dysbiosis and abnormal SCFA metabolism. The reduction in key SCFA-producing taxa, their positive correlations with SCFAs levels, and the negative correlations of both with fatigue severity solidify a functional link between gut microbial depletion, reduced SCFAs, and clinical symptoms in CFS. Higher dietary fiber intake may partially ameliorate SCFAs metabolic disturbances in CFS patients.",

However, its mechanisms of protection against age-related cognitive decline, especially those mediated via the gut-brain axis, are not fully understood. This study investigated the role of kaempferol in alleviating D-galactose-induced brain aging and elucidated its functional mechanisms related to gut microbiota composition, microbial metabolite production, and intestinal barrier integrity. An aging mouse model was induced by D-galactose and subsequently treated with kaempferol. Results revealed that kaempferol significantly ameliorated anxiety-like behaviors and spatial working memory deficits in D-galactose-treated mice. In the hippocampus, it reduced neuronal loss, upregulated synaptic plasticity-related genes (Bdnf and Snap25), and suppressed neuroinflammation through inhibition of microglial activation and the TLR4/Myd88 signaling pathway. Importantly, kaempferol restored intestinal barrier integrity, as indicated by increased expression of colonic MUC2 and tight junction proteins (Zo-1 and Occludin). It also markedly reshaped gut microbiota composition by enriching beneficial genera such as Faecalibaculum and Akkermansia, which correlated with elevated fecal propionate and butyrate levels, and a reduction in serum LPS. Our findings demonstrate that kaempferol mitigates D-galactose-induced cognitive impairment by modulating gut microbiota, increasing beneficial SCFA production, enhancing gut barrier function, and subsequently inhibiting systemic and neuroinflammation. This study provides mechanistic support for kaempferol as a dietary intervention strategy to promote brain health via the gut-brain axis.",

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.",

Sacc.Chaidam on gut microbiota in Tibetan Plateau population based on in vitro model.\nAbstract: The intercellular polysaccharides derived from Agaricus bitorquis (Qu\u00e9l.) Sacc. Chaidam (ABIPs) are macromolecules exhibiting significant biological activity and outstanding anti-hypoxia properties. However, the digestive traits of ABIPs within the intestinal microbiota and their adaptive mechanisms to hypoxia in high-altitude populations remain poorly understood. The objective of this study was to investigate the anti-hypoxia mechanism of ABIPs at the small-molecule level through the utilization of the in vitro fermentation model of intestinal flora and the cell hypoxia models. The results indicated that under conditions of hypoxic stress, the total amount of monosaccharides and uronic acids (MUAs) metabolized by ABIPs in the plateau group was comparatively high, predominantly mannose. Furthermore, the level of short-chain fatty acids (SCFAs) produced through their metabolism was also significantly higher than that of the plain group, with acetic-acid, propionic-acid, and butyric-acid constituting a relatively large proportion. Additionally, in the plateau group, the metabolism of ABIPs increased the abundance of Prevotella and Alloprevotella, while the abundance of Collinsella decreased notably. In contrast, the metabolites produced by ABIPs in the plateau group (mainly SCFAs) had a more pronounced inhibitory effect on the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) signaling pathway than in the plain group. Overall, ABIPs may enable cells to develop hypoxia tolerance by enhancing hypoxia-consuming metabolic levels, rebalancing the gut microbiota, and stabilizing the HIF-1\u03b1 signaling pathway, thereby protecting the body from hypoxia damage.",

Its stem bark is valued in ethnomedicine, but its potential anti-Alzheimer's disease (AD) effects are scientifically unexplored. This research has examined the neuroprotective effects of the ethyl acetate fraction of P. cineraria bark (Pc-EA) against AlCl3-induced AD pathology, focusing on behavioral, biochemical, histological, and molecular outcomes. Diseased rats were treated with Pc-EA (30, 100, and 300\u00a0mg/kg) for 42 days. Cognitive and affective functions were evaluated with behavioral tests on days 29-42. Biochemical assays measured oxidative stress and cholinesterase activity, while RT-PCR quantified neuroinflammatory markers. Histopathological examination was performed to evaluate the integrity of hippocampal regions. Bioactive compounds were identified by phytochemical profiling (HPLC, GC-MS), and molecular docking was performed to assess binding interactions with acetylcholinesterase. AlCl3 exposure impaired memory, augmented anxiety and depression-like behavior, elevated oxidative stress, AChE activity, and induced hippocampal neurodegeneration with upregulated BACE-1, Tau, Caspase-3, and NF-\u03baB alongside downregulated BDNF. These changes were reversed by Pc-EA (100\u00a0mg/kg), which enhanced cognitive function, restored antioxidant defense, inhibited AChE and neuroinflammatory markers, and maintained hippocampal architecture. Bioactive phytoconstituents (chlorogenic acid, kaempferol, quercetin), which exert anti-amyloidogenic, antioxidant, anti-inflammatory, and acetylcholinesterase inhibitory effects, were identified by HPLC and GC-MS, and their potential roles were corroborated via in silico validation. Pc-EA demonstrated multi-targeted neuroprotection in AlCl3-induced AD, which is consistent with ethnomedicinal claims. These findings indicate P. cineraria as a potential modulator of AD through antioxidant, anti-inflammatory, anti-amyloidogenic, and neurotrophic mechanisms.",

Altered signaling through hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) and PI3K/AKT cascades contributes to neuronal vulnerability. Canagliflozin (Cana), a sodium-glucose cotransporter-2 inhibitor, has shown cognitive benefits in experimental studies. Here, we evaluated whether Cana mitigates 3-nitropropionic acid (3NP, 10\u00a0mg/kg, i.p., 14\u00a0days)-induced HD-like neurotoxicity in rats. Animals received Cana (5 or 10\u00a0mg/kg, p.o.) daily for 14\u00a0days, followed by behavioral assessments (open-field, Morris water maze, novel object recognition), histopathology, immunohistochemistry, and biochemical assays. Cana treatment significantly improved locomotor and memory performance, reduced striatal histopathological alterations, and attenuated GFAP immunoreactivity. Mechanistically, Cana upregulated HIF-1\u03b1 and downstream GLUT1/GLUT3/HKII, restored PI3K/AKT/CREB/BDNF signaling, and enhanced SIRT1/PGC-1\u03b1/Nrf2 antioxidant responses, while suppressing inflammatory mediators and caspase-3 activation. These findings highlight Cana as a promising disease-modifying strategy for HD by targeting both energy metabolism and pro-survival pathways.",
"41459064": "ID: 41459064\nTitle: Potential effects of cinnamon on cancer prevention and progression.\nAbstract: Cinnamon has been used medicinally for centuries, but recently in vitro research has suggested it may have a role in cancer prevention and potentially treatment. The search for alternative and subjunctive therapies is essential due to the public demand and the increasing cost of healthcare. Here we review the biologically active components of cinnamon and discuss the methods of potential cinnamon activity against cancer, including: transcription factor regulation and kinase activity. Nuclear Factor kappa B (NF\u03baB) is a stress sensitive transcription factor that regulates transcription of genes involved in tumor progression and is inhibited by cinnamon components. Another way that cinnamon inhibits tumor growth is by suppression of transcription factor activator protein 1 (AP1) which interacts with genes responsible for apoptosis, metastasis and inflammation. Hypoxia-inducible transcription factor 1 (HIF1) and vascular endothelial growth factor (VEGF) are involved in angiogenesis, especially in the tumor microenvironment. The HIF1-VEGF pathway is a target of cinnamaldehyde, a compound found in cinnamon. Nuclear factor erythroid related factor 2 (Nrf2) is also examined and has been indicated to affect cancer progression and potentially provide preventative measures; various cinnamon derivatives target Nrf2. A cinnamaldehyde derivative has been implicated in a reduction of the mitogen-activated protein kinases (MAPKs), which are a group of kinases that regulate proliferation. Additionally, cinnamon components have been tied to cancer prevention by positively affecting the gut microbiome and inhibiting inflammation. The review concludes with a discussion of the future research needed, including the need for clinical studies and potential risk associated with cinnamon intake.",
"41470904": "ID: 41470904\nTitle: From Microbiota to Metabolomics: How Corylus heterophylla Fisch. Male Flower Extract Shields Mice from Cognitive Decline.\nAbstract: Background/Objectives: Emerging evidence suggests that hippocampal neuroinflammation (HNF) drives cognitive decline via dysregulation of the microbiota-gut-brain axis. Corylus heterophylla Fisch. male flower extract (CFE), a flavonoid-rich by-product of hazelnut processing, presents a promising yet unexplored neuroprotective candidate. This study investigated the preventive effects and mechanisms of CFE against HNF-induced cognitive decline. Methods: In the present study, mice were pretreated with CFE (200 mg/kg) before the Lipopolysaccharide (LPS) administration. Cognitive function, inflammation, core pathology, neuroplasticity, gut microbiota and serum metabolites were assessed. The chemical composition of CFE was analyzed by UHPLC-MS and its direct immunomodulatory effects were investigated in BV2 cells. Results: Behavioral assessments demonstrated significant therapeutic efficacy. This was evidenced by the recovery from hippocampal damage, accompanied by reduced levels of core pathological markers (A\u03b21-42, Tau, p-Tau (Ser404), GSK-3\u03b2), decreased expression of pro-inflammatory mediators including IL-33, elevated levels of neurotrophic factors (BDNF and MAP2), and attenuated abnormal activation of astrocytes and microglia. The 16S rRNA analysis confirmed that CFE ameliorated gut microbial dysbiosis. Notably, CFE significantly increased the relative abundance of Muribaculaceae and Lachnospiraceae, while significantly decreased Staphylococcus and Helicobacter. Metabolomics revealed enhanced levels of \u03b1-linolenic acid (ALA), serotonin (5-HT) and acetic acid, which correlated positively with Muribaculaceae and Lachnospiraceae. Phytochemical analysis identified luteolin and kaempferol as the predominant flavonoids in CFE. In BV2 cells, CFE, luteolin and kaempferol shifted microglial polarization from the M1 phenotype toward the M2 phenotype. Conclusions: CFE alleviated HNF-induced cognitive decline by regulating microbiota-gut-brain axis and microglial M1/M2 polarization.",

While probiotic therapies show promise, their mechanisms in mitigating neuropsychiatric comorbidities remain unclear. Here, we investigated the therapeutic potential of Akkermansia muciniphila-derived extracellular vesicles (AmEVs) in a murine model of dextran sulfate sodium (DSS)-induced colitis and associated cognitive deficits. AmEVs administration significantly alleviated colitis severity, as evidenced by improved weight retention, reduced disease activity index scores, and colon length restoration. Concurrently, AmEVs reversed colitis-driven cognitive impairments, restoring Y-maze and novel object recognition performance to baseline levels. Mechanistically, AmEVs repaired intestinal and blood\u2012brain barrier integrity by upregulating tight junction proteins, suppressed neuroinflammation via reduced hippocampal pro-inflammatory cytokines, and inhibited microglial/astrocyte activation. Gut microbiota analysis revealed that AmEVs-mediated enrichment of beneficial Bifidobacterium and suppression of pathogenic Bacteroides and Mucispirillum, alongside restored short-chain fatty acid (SCFA) production. Crucially, AmEVs bidirectionally regulated tryptophan metabolism, reducing colonic serotonin (5-HT) overproduction while restoring hippocampal 5-HT levels and 5-HT1A receptor expression. This was accompanied by enhanced synaptic plasticity and BDNF upregulation in the hippocampus. Proteomic and biodistribution studies confirmed AmEVs' delivery of metabolic regulators to hippocampal neurons, including the key protein Amuc_1100,directly enhancing 5-HT production in vitro. Our findings establish AmEVs as a multifaceted therapeutic agent that concurrently resolves gut inflammation and cognitive deficits via gut-brain axis modulation, offering novel strategies for IBD-related neuropsychiatric comorbidities. Further research is warranted to validate critical vesicular components and optimize clinical translation.",
"41579799": "ID: 41579799\nTitle: Dihydromyricetin improves DSS-induced colitis and behavioral disorders by regulating the microbiota-gut-brain axis balance and inhibiting the activation of NLRP3 inflammasome.\nAbstract: Patients with inflammatory bowel disease (IBD) commonly exhibit psychiatric symptoms, such as anxiety and depression. However, studies on drugs addressing the concurrent amelioration of these symptoms in this patient population are rare. Previous studies have suggested that dihydromyricetin (DHM) may show therapeutic potential for IBD. This study investigated the therapeutic effects of DHM on dextran sulfate sodium (DSS)-induced colitis and associated behavioral disorders in mice. The findings of the experiments indicated that DHM could ameliorate colitis symptoms, including changes in body weight, colon length, disease activity index (DAI) scores, and histopathological damage. Furthermore, DHM improved the behavioral impairments observed in colitis mouse model, as evidenced by results from the open field test, elevated plus maze test, and tail suspension test, along with hippocampal histopathological assessments. Molecular analysis revealed that DHM notably suppressed the activation of NLRP3 inflammasome and IL-1\u03b2 in both the colon and the hippocampus. DHM enhanced the intestinal barrier, elevated brain-derived neurotrophic factor (BDNF) levels in the hippocampus and serum, and concurrently reduced microglia activation. DHM lowered the levels of IL-1\u03b2, tumor necrosis factor-\u03b1 (TNF-\u03b1), and lipopolysaccharide (LPS) in the serum. 16S rDNA sequencing results indicated that DHM could modulate DSS-induced gut microbiota dysbiosis, enriching various beneficial metabolic and neuromodulatory pathways. Metabolomic analysis demonstrated that DHM notably elevated acetic acid, propionic acid, and butyric acid levels in intestinal feces. Network pharmacology analysis identified the central intersecting genes of DHM, ulcerative colitis (UC), and neuroinflammation. Differential gene expression analysis underscored IL-1 \u03b2 as a pivotal target for the co-occurrence of UC and psychiatric conditions. These findings imply that DHM may ameliorate DSS-induced colitis and concomitant behavioral disturbances in mice, underscoring its potential as a natural therapeutic agent for IBD accompanied by psychiatric comorbidities.",

Roseburia intestinalis (R. intestinalis) is consistently reduced in PD; however, its functional contribution remains unknown. We performed two complementary mouse experiments using a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model. In the primary intervention experiment, mice received live or heat-killed R. intestinalis, followed by behavioral assessments and multi-layer analyses, including immunofluorescence, western blotting, enzyme-linked immunosorbent assay, quantitative polymerase chain reaction, 16S rRNA sequencing, metabolomics, and transcriptomics. In a separate mechanistic experiment, subdiaphragmatic vagotomy was introduced to interrogate vagus-dependent gut-brain communication, with key behavioral and inflammatory endpoints assessed. Live R. intestinalis improved rotarod, pole, and grip strength performance and preserved tyrosine hydroxylase-positive neurons in the substantia nigra; however, these effects were not observed in the heat-killed group. Live R. intestinalis treatment also reduced glial reactivity, restored brain-derived neurotrophic factor expression, and maintained blood-brain barrier integrity. Systemically, R. intestinalis lowered serum lipopolysaccharide, tumor necrosis factor-\u03b1, and interleukin-6 levels; preserved colonic structure; and restored mucin-secreting goblet cell function. MPTP-induced dysbiosis was partially corrected. Metabolomic profiling revealed restoration of several acyl-carnitines and higher acetic acid levels. Transcriptomic analysis showed increased immediate early genes after MPTP, and the elevated c-Fos in the substantia nigra was partially normalized by R. intestinalis. Importantly, vagotomy abolished the central neuroprotective and anti-inflammatory effects but did not affect peripheral cytokine suppression, indicating both vagus-dependent and vagus-independent pathways. R. intestinalis supplementation alleviated motor impairments, reduced neuroinflammation, preserved dopaminergic neurons, and improved intestinal and metabolic alterations in mice with an MPTP-induced PD model. Its protective actions may involve both central and peripheral mechanisms, potentially including gut-brain communication pathways. R. intestinalis may be a promising candidate for microbiota-based strategies against PD.",

Indole-3-lactate (ILA) is reduced in persons with MS and improves MS clinical scores in animal models via its anti-inflammatory remyelinating properties. The ILA/indole-3-acetate (IAA) (ILA/AA) index is considered a neuroprotection index. Physical exercise and diet can modify gut microbiota and indole metabolism. This secondary analysis of a randomized control trial aimed to assess the effects of acute and chronic exercise on serum indoles in relapsing-remitting MS (RRMS). Thirty-one RRMS patients (\u2265\u200970% session attendance) completed a 10\u2009week multimodal functional training (60\u2009min, 3\u00d7/week) vs. a waitlist control group. Blood samples were collected at baseline and compared to a matched healthy control group, and after 10\u2009weeks for the assessment of chronic effects. Additionally, acute effects of a single bout of exercise were assessed with a blood sample before, during, and immediately after one interim training session. Serum indole concentrations were measured using LC-MS/MS. Baseline indole levels in RRMS patients differed from those of matched healthy controls, and reduced ILA levels were observed. The 10\u2009week intervention increased the ILA/IAA index, while a single exercise bout induced an increase in both ILA and ILA/IAA. Multimodal functional training over 10\u2009weeks led to an improved ILA/IAA index suggesting a neuroprotective shift in gut microbiota composition, and a single bout acutely increases the circulating level of ILA.

Probiotics such as Lactobacillus rhamnosus GG and Bifidobacterium longum 1714 have been associated with neuroactive effects, yet the molecular mechanisms linking microbial genomic potential to host neuronal responses remain poorly defined. This study aimed to integrate microbial genomics, neurotranscriptomics, and in vitro validation to unravel the neuromodulatory effects of L. rhamnosus GG and B. longum 1714. Whole-genome functional annotation, metabolic pathway prediction, and biosynthetic gene cluster analysis were performed to identify neuroactive potential. Neuronal RNA-seq datasets (n = 3 biological replicates per condition) were analyzed using differential expression, WGCNA, and GSEA to capture transcriptomic responses. Multi-omics integration (CCA, DIABLO, SPIEC-EASI) linked microbial pathways with neuronal gene modules. In vitro assays using SH-SY5Y and iPSC-derived neurons validated predictions through measurements of cell viability, oxidative stress, neurotransmitter release (ELISA), qPCR of synaptic and inflammatory genes, and extracellular vesicle characterization including EV transcript profiling. Genomic analysis revealed that L. rhamnosus GG was enriched in \u03b3-aminobutyric acid (GABA) and SCFA pathways, while B. longum 1714 carried tryptophan-indole metabolism genes. Transcriptomic profiling demonstrated upregulation of synaptic genes (BDNF, SYN1), showed upregulation of synaptic genes (BDNF, SYN1), serotonergic transporters (SLC6A4, TPH2), and suppression of inflammatory mediators (IL-6, TNF-\u03b1). Integration analyses identified two major subnetworks: a \"neurotransmission module\" driven by L. rhamnosus GG and a \"serotonin-immune module\" driven by B. longum 1714. In vitro validation confirmed increased GABA (1.7-fold) and serotonin (1.5-fold) release, reduced ROS (-18 to -22%), and EV transcript enrichment for synaptic and anti-inflammatory markers. This multi-omics study demonstrates mechanistic evidence that probiotics exert complementary neuromodulatory effects: L. rhamnosus GG primarily enhances GABAergic and SCFA-mediated synaptic pathways, whereas B. longum 1714 regulates the tryptophan-serotonin-immune axis. Together, these findings support the therapeutic potential of precision probiotics for neurological health and establish a systems-level framework for probing host-microbe interactions.",

Despite its clinical burden, effective therapies that target this multi-organ pathology remain limited. \u03b2-Caryophyllene (BCP), an antioxidant and anti-inflammatory dietary sesquiterpene, has not been evaluated for its ability to modulate liver-brain crosstalk in HE. This study investigated the hepatoprotective and neuroprotective effects of BCP in a rat model of thioacetamide (TAA)-induced HE. Rats received TAA (200\u202fmg/kg, i.p.) for three days, followed by BCP (100-400\u202fmg/kg) for 14 days. A comprehensive evaluation included serum biochemistry, oxidative stress indices, inflammatory cytokines, apoptosis-related proteins, neurotrophic factors (BDNF), astroglial activation marker (GFAP), ER stress regulators (GRP78, IRE1, XBP1, PERK, CHOP, ATF6), histopathology, and behavioral outcomes. TAA caused severe hepatic and cerebral injury with elevated liver enzymes, oxidative and inflammatory mediators, ER stress dysregulation, pro-apoptotic signaling, reduced BDNF and GFAP, and impaired motor and exploratory behaviors. BCP treatment dose-dependently restored biochemical and molecular parameters, suppressed oxidative stress and neuroinflammation, normalized ER stress signaling, promoted anti-apoptotic pathways, preserved BDNF and maintained astroglial status as reflected by GFAP, and improved histoarchitecture. Importantly, moderate to high doses fully restored locomotor and exploratory activity, indicating coordinated protection across the hepato-encephalic axis. Here, for the first time, the BCP concurrently mitigates hepatic and cerebral pathology via oxidative, inflammatory, apoptotic, and ER stress pathways, supporting its translational potential as a dual hepatoprotective and neuroprotective candidate for xenobiotic-induced HE and related liver-brain disorders.",

This may help explain why depression is commonly observed in cancer populations, where it is associated with poorer treatment adherence, diminished quality of life, and elevated mortality. Conversely, depression associated with an elevated cancer risk, potentially mediated by factors, such as neuroimmune dysregulation, chronic inflammation, and unhealthy lifestyles. Shared mechanisms include stress-induced \u03b2-adrenergic signaling, neuroinflammation, kynurenine pathway activation, and gut-brain-tumor axis disruptions involving bacterial metabolites like acetate. Common lifestyle factors such as smoking and sleep disruption, may further link both conditions through pathways like Wnt/\u03b2-catenin and JAK/STAT. Integrated treatment strategies combining anti-inflammatory medications such as non-steroidal anti-inflammatory drugs (NSAIDs) or tumor necrosis factor-\u03b1 (TNF-\u03b1) inhibitors, psychotropic medications such as selective serotonin reuptake inhibitors (SSRIs), lifestyle modifications (e.g., exercise, Mediterranean diet) and psychotherapy (e.g., CBT) are promising for breaking the potential depression-cancer cycle and improving outcomes.",
"41679674": "ID: 41679674\nTitle: The role of indole metabolites derived from gut microbiota in Parkinson's disease: A comprehensive review.\nAbstract: Emerging evidence suggests that Parkinson's disease (PD) extends beyond the brain and involves early disturbances along the gut-brain axis. Among the metabolites shaping this communication, bacterial products derived from tryptophan, particularly indole compounds, are gaining attention as key biochemical links between intestinal dysbiosis and neurodegeneration. Multi-omics studies consistently show a reduction in commensal bacteria capable of producing beneficial indoles and an enrichment of Enterobacteriaceae that redirect tryptophan catabolism toward toxic intermediates. This shift disrupts epithelial and blood-brain barrier function and amplifies inflammatory and oxidative stress pathways within the central nervous system. Protective metabolites such as indole-3-propionic acid (IPA), indole-3-acetic acid (IAA), indole-3-lactic acid (ILA), and indole-3-carbinol (I3C) exert antioxidant, barrier-stabilizing, and anti-inflammatory effects through receptors including the aryl hydrocarbon and pregnane X receptors. Conversely, uremic indoles such as indoxyl sulfate (IS) and p-cresyl sulfate (pCS) activate microglia and astrocytes, promote \u03b1-synuclein aggregation, and accelerate dopaminergic neuron loss. Together, these findings support a view of PD as a metabolic imbalance between neuroprotective and neurotoxic indoles. Understanding how microbial and host pathways regulate this balance may open opportunities for early diagnosis and targeted interventions that integrate metabolism, immunity, and neuroprotection.",

Beans (Phaseolus vulgaris) are rich in non-digestible carbohydrates and polyphenols, but whether kidney bean varieties differing in seed coat colour exert distinct effects on inflammation in obesity remains unclear. Objective: To determine whether supplementation of an obesogenic high-fat (HF) diet with white or dark red kidney beans modulates gut microbiota, SCFAs, and intestinal, systemic, and neuroinflammatory outcomes. Methods: Male C57Bl/6N mice (n = 12/group) were fed a basal diet (BD; modified AIN-93G), an HF diet (60% kcal from fat), or an HF diet supplemented with 15% cooked white (HF + WK) or dark red kidney beans (HF + DK) for nine weeks. Outcomes included cecal microbiota composition, predicted KEGG pathways with taxon contributors mapped with BURRITO (a tool for linking predicted microbial functions to contributing taxa), and SCFA-related pathways; cecal and fecal SCFA concentrations; colon histomorphometry and expression of gut barrier junction and inflammatory genes; serum cytokines and adipose hormones; and hippocampal inflammatory and barrier genes. Results: Mice consuming bean-supplemented HF diets had higher microbial diversity, enrichment of SCFA-producing taxa (Prevotella, Lactobacillus, Muribaculaceae), and lower obesity-associated genera versus HF alone (Mucispirillum, rc4-4). Bean diets elevated cecal acetate and butyrate concentrations, which aligned with increases in predicted acetate kinase in both bean groups versus HF and BD, and butyrate kinase in HF + DK versus BD. Bean supplementation attenuated HF-induced reduction of goblet cells and systemic interleukin (IL)-10. The HF + DK group had lower colonic tumour necrosis factor (TNF)-\u03b1 and partially attenuated hippocampal IL-6. SCFAs were inversely associated with systemic and neuroinflammatory markers in HF + DK mice. Conclusions: Kidney bean supplementation mitigated HF diet-induced intestinal, systemic, and neuroinflammatory disturbances in male mice, with microbiota and SCFA modulation. Further, dark red beans exerted stronger anti-inflammatory effects, highlighting the role of seed coat colour in bean-mediated obesity outcomes.",

This study aimed to explore the therapeutic effects of XFZY on PSD and its possible modulation of the gut microbiota-gut-brain axis in a rat model. Wistar rats were randomly assigned to sham, PSD, three XFZY dose (0.216, 0.432, 0.864 g/kg), and fluoxetine (1.80 mg/kg) groups (n = 12 per group). The PSD model was established using transient middle cerebral artery occlusion (t-MCAO) combined with chronic unpredictable mild stress (CUMS), followed by 28 days of XFZY administration. In a separate experiment, gut microbiota was depleted via antibiotic cocktails, with rats divided into sham, PSD, XFZY medium Dose (XFM), pseudo-germ-free (PGF) and PGF + XFM (PGFX) groups. Behavioral tests indicated that XFZY ameliorated depressive-like behaviors, with the medium dose (0.432 g/kg) showing the most significant effect. Histological analysis using hematoxylin and eosin (H&E) and Nissl staining revealed that XFZY alleviated colonic and neuronal damage. Furthermore, 16S rRNA sequencing and gas chromatography revealed that XFZY modulated gut microbiota composition, increased species richness, and elevated levels of short-chain fatty acids such as acetic acid, propionic acid, and butyric acid. Enzyme-Linked Immunosorbent Assay (ELISA) results showed that XFZY reduced pro-inflammatory cytokines - interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1), while immunohistochemistry indicated enhanced intestinal barrier function and reduced neuroinflammation. Furthermore, after depletion of gut microbiota using antibiotic cocktails, these therapeutic effects of XFZY were abolished. In summary, XFZY may alleviate PSD by modulating the gut microbiota and regulating the gut-brain axis, offering a promising direction for future therapeutic research.",

In this study, we demonstrated that A. muciniphila administration improve cognitive deficits and reduce amyloid-beta (A\u03b2) deposition in APP/PS1 mice, a transgenic model of AD. Subsequently, it is revealed that A. muciniphila administration significantly alters gut microbiota diversity and composition. Mechanically, our metabolomics analysis of cecal contents indicates A. muciniphila administration increases short-chain fatty acids (SCFAs) derived from the intestinal microbiota, including butyric acid and acetic acid. Significantly, in APP/PS1 mice with the A. muciniphila administration, targeted metabolomics identify that the production of 62 metabolites are increased such as indole-3-acetic acid (IAA), tryptophan, acetic acid and cinnamic acid, as well as aconitic acid and threonine, et al.; the production of 28 metabolites are decreased such as isoleucine and N-acetylneuraminic acid (NANA) as well as ornithine and docosapentaenoic acid (DPA), et al. It is also identified by cytokine analysis of plasma that A. muciniphila administration reduces peripheral pro-inflammatory cytokines interleukin-6 (IL-6), IL-1\u03b2, IL-17 and tumor necrosis factor-alpha (TNF-\u03b1), et al., whereas it increases anti-inflammatory cytokines, such as IL-4, IL-10 and IL-22, et al. There is no any change of other cytokines, such as interferon-gamma (IFN-g), IL-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF), et al. Interestingly, a significant positive correlation is observed between the increased IAA, tryptophan as well as acetic acid and cognitive function indicators. At the same time, A. muciniphila administration improves cognitive deficits, alleviates neuroinflammation and A\u03b2 deposition via AhR/NF-\u03baB/NLRP3 signaling pathway in APP/PS1 mice. In summary, our findings suggest A. muciniphila is a promising approach for preventing AD progression by microbiota-gut-brain axis.",

Emerging evidence supports the gut-origin hypothesis, highlighting gut microbiota dysbiosis as a contributing factor in PD pathogenesis. Our previous clinical study showed that Bacteroides coprocola (B. coprocola), a gut bacterium producing short-chain fatty acids (SCFAs), was significantly reduced in PD patients. This study was aimed to investigate the potential of B. coprocola in ameliorating PD pathology and explore the underlying mechanisms in a rotenone-induced PD mouse model. The rotenone-induced PD mouse model was treated by orally administering B. coprocola for three weeks. Immunofluorescence, Western blotting, flow cytometry, 16S rRNA sequencing, and metabolomics were performed to assess midbrain and intestinal changes, NLRP3 inflammasome activation, macrophage polarization, gut microbiota, and SCFA levels. In vitro, LPS-stimulated bone marrow-derived macrophages were used to validate the role of NLRP3 signaling in macrophage polarization following sodium acetate and sodium butyrate treatment via siRNA and molecular assays. B. coprocola treatment alleviated PD-related motor deficits, neuroinflammation, gut microbiota dysbiosis, and intestinal barrier permeability in the rotenone-induced PD mouse model. Mechanistically, B. coprocola reshaped the gut microbiota composition and modulated macrophage polarization, which were associated with the inhibition of the NLRP3 inflammasome signaling pathway. Furthermore, in vitro experiments confirmed that the acetate and butyrate-key metabolites of B. coprocola-attenuated the inflammatory responses and promoted M2-like macrophage polarization via free fatty acid receptor (FFAR) 2/3 receptors, thereby suppressing NLRP3 activation. In conclusion, B. coprocola treatment can improve motor deficits, neuroinflammation, and intestinal function in the rotenone-induced PD mouse model. The effects are associated with microbiota remodeling, regulation of macrophage polarization, and inhibition of the NLRP3 inflammasome pathway. Acetate and butyrate, key metabolites of B. coprocola, might play an important role in promoting M2 macrophage polarization through FFAR2/3 receptors.",
"41762442": "ID: 41762442\nTitle: In silico evaluation of bioactive compounds as potential inhibitors targeting HIF-1\u03b1/VEGFA/BACE1 pathway against Alzheimer's disease.\nAbstract: Neurodegenerative disorders such as Alzheimer's disease (AD) are characterized by progressive neuronal degeneration, predominantly caused by the accumulation of amyloid-beta (A\u03b2) and neuroinflammatory processes. Hypoxia, characterized by diminished oxygen levels, intensifies these mechanisms by stimulating hypoxiainducible factor 1-alpha (HIF-1\u03b1), potentially enhancing BACE1 enzyme activity and resulting in increased A\u03b2 synthesis and render neurons especially susceptible to hypoxia, exacerbating disease progression. Existing therapies are constrained by inadequate medication distribution across the blood-brain barrier and associated adverse effects. This study aims to identify potential therapeutic agents targeting HIF-1\u03b1, VEGFA, BACE1 key molecules involved in AD by exploring neuroprotective effects of bioactive compounds like benzyl isothiocyanate (BITC), Aurantiamide Acetate (AA), and galantamine, with the goal of developing more effective, targeted treatments. We used in silico screening, such as molecular docking and ADMET analysis, to assess the binding affinity, pharmacokinetics, and toxicity of potential inhibitors, followed by in\u00a0vitro testing. Results identified several compounds with strong binding affinities and favorable ADMET profiles as potential inhibitors of HIF-1\u03b1, VEGFA, BACE1 and experimental data support that hypoxia, via HIF-1\u03b1, upregulates BACE1, increasing A\u03b2 production and contributing to AD. Targeting these pathways may offer a multi-faceted approach to therapy, reducing neuroinflammation and amyloid pathology. In silico screening of potential molecules across different pathogenic pathways in Alzheimer's disease shows promise in developing successful therapeutic methods and continued validation may result in more tailored and safer medicines that address underlying neurodegenerative pathways.",
"41794536": "ID: 41794536\nTitle: Fermented red quinoa (FRQ) effectively mitigates chronic alcohol-induced cognitive impairment and hepatic steatosis through multi-mechanistic pathways.\nAbstract: Long-term alcohol consumption drives systemic damage through metabolites such as acetaldehyde, which trigger oxidative stress, inflammation, and gut dysbiosis. This study evaluated the protective effects of fermented red quinoa (FRQ) in an alcohol-exposed mouse model, with a focus on cognitive function. Male C57BL/6J mice were randomized into three groups for a 28-day study: a normal control, an alcohol-treated group gavaged with ethanol (1\u00a0mL/100\u00a0g\u00b7BW), and a group receiving the same ethanol dose co-administered with FRQ powder (human equivalent dose: 9\u00a0g/60\u00a0kg\u00b7BW). Our results demonstrated that fermentation with Lactobacillus kisonensis significantly increased the content of phenolic compounds (e.g., quercetin and veratric acid) in FRQ. FRQ intervention improved cognitive function, ameliorated synaptic structural impairment and blood-brain barrier disruption, and attenuated hepatic steatosis. The protective mechanisms involved three pathways: 1) The specific phenolic compounds in FRQ promoted alcohol metabolism by regulating ADH/ALDH activity, leading to reduced acetaldehyde levels. As a primary initiating pathway, this metabolic enhancement dominantly attenuated subsequent oxidative stress and inflammation, mitigating injury in the liver, brain, and colon. 2) It directly modulated AP-1 subunits (\u0394FOSB/JUND), restored BDNF, and rebalanced the glutamate/GABA systems. 3) It regulated the gut-liver-brain axis by remodeling the gut microbiota (e.g., enriching butyrate-producing Butyricicoccus), reinforcing intestinal barrier integrity, and thereby suppressing systemic LPS translocation and inflammation. In conclusion, FRQ mitigates alcohol-induced cognitive and hepatic damage via multiple mechanisms, highlighting its promise as an integrative dietary intervention.",
"41824184": "ID: 41824184\nTitle: Prebiotics attenuate depressive-like behavior, neuroinflammation and synaptic plasticity in Parkinson's disease by modulating butyrate-producing gut bacteria.\nAbstract: Parkinson's disease (PD) remains a challenging disease for treatment, which is usually polypharmacological. In addition to motor symptoms, non-motor symptoms such as depression are present in approximately 40% of patients, contributing to the loss of quality of life. In the last two decades, a growing body of evidence has emerged regarding the involvement of the microbiota-gut-brain axis in both PD and depression. Fructooligosaccharides (FOS) and galactooligosaccharides (GOS) are prebiotic fibers that can be fermented by the gut microbiota, which produce metabolites called short-chain fatty acids (SCFAs), whose effects can contribute to improvement in neurodegenerative and psychiatric conditions. This study analyzed the effects of FOS and GOS administration in a rotenone-induced PD model and demonstrated a relief of motor symptoms and depressive-like behavior, followed by an increase of brain serotonin and its respective receptor (SERT). FOS and GOS treatment also led to an increase in SCFAs-producing gut bacteria with significantly higher levels of serum and brain butyrate. Furthermore, in the intestine, prebiotics reduced the accumulation of \u03b1-synuclein, decreased inflammation, and improved the expression of zonula occludens and occludin. FOS and GOS also attenuated the loss of dopaminergic neurons and reduced neuroinflammation by decreasing \u03b1-synuclein, IBA-1, GFAP, iNOS, p-NFkB, and IL1-\u03b2 levels in the substantia nigra and prefrontal cortex. In addition, these prebiotics improved neuroplasticity by promoting the expression of butyrate receptors (GPR43 and GPR109), BDNF, p-CREB, and synaptic protein PSD-95. In conclusion, FOS and GOS administration attenuatted depressive-like behavior, neuroinflammation, and synaptic plasticity in Parkinson's disease by modulating butyrate-producing gut bacteria.",
"41839449": "ID: 41839449\nTitle: Resveratrol Attenuates Neuroinflammation and Gut-Brain Axis Dysfunction Induced by Lead and Cadmium Co-Exposure by Modulating Gut Microbiota in Rats.\nAbstract: Resveratrol (RSV), a dietary polyphenol widely present in traditional medicinal plants and foods, exhibits antioxidant and anti-inflammatory properties that are relevant to ethnopharmacological strategies for protecting against environmental neurotoxicants. Given increasing real-world co-exposure to lead (Pb) and cadmium (Cd), elucidating RSV's capacity to preserve gut-brain axis (GBA) homeostasis has direct translational relevance for populations relying on phytochemical interventions. Sprague-Dawley rats were randomized into control, Pb-Cd model, and RSV treatment groups (10, 20, or 40\u2009mg/kg). For 4\u2009weeks, rats received Pb (300\u2009mg/L) and Cd (50\u2009mg/L) in drinking water with daily RSV. Cognitive function was assessed by Morris water maze; barrier integrity by Evans blue assay, histology, and Western blot for ZO-1/Occludin; synaptic ultrastructure by TEM; microbiota composition by 16S rRNA sequencing; and short-chain fatty acids (SCFAs) by GC-MS. Neurotransmitters (5-HT, GABA, SP, VIP) and cytokines (IL-6, IL-1\u03b2, TNF-\u03b1) were measured by ELISA. RSV improved spatial learning, reduced EB extravasation, preserved synaptic ultrastructure and proteins (BDNF, SYN, PSD-95), and restored intestinal architecture with increased ZO-1/Occludin. RSV attenuated cytokine release, normalized goblet cells, reversed dysbiosis by restoring Lactobacillaceae/Prevotellaceae, and increased acetate, propionate, and butyrate. It reinstated 5-HT and GABA while reducing SP and restoring VIP across serum, colon, and hippocampus. RSV attenuated Pb-Cd-associated neurotoxicity and was accompanied by improved intestinal and BBB-related readouts, partial normalization of gut microbiota features and SCFA levels, and preservation of synaptic and neurotransmitter-related markers, consistent with a link to gut-brain axis function. This study is among the first to test RSV in a Pb-Cd co-exposure model using a multi-dose regimen with integrated behavioral, barrier, microbial, and neurochemical endpoints.",
"41868184": "ID: 41868184\nTitle: Advances and Therapeutic Potential of Anthraquinone Compounds in Neurodegenerative Diseases: A Comprehensive Review.\nAbstract: Rhubarb, traditionally used in China for neurological disorders, has recently attracted considerable scientific attention for its neuroprotective and cerebrovascular benefits. The main therapeutic components of rhubarb are anthraquinones, including emodin, aloe-emodin, chrysophanol, rhein, and physcion. Accumulating experimental evidence indicates that anthraquinones are of importance in neurodegenerative diseases (NDDs), such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and multiple sclerosis. However, as a promising candidate for drug development, the mechanisms by which anthraquinones treat NDDs have not been systematically reviewed. Therefore, this article outlines the anti-neurodegenerative effects of anthraquinones, focusing on their molecular mechanisms. This article reviews recent research progress of anthraquinones in NDDs, focusing on their potential targets and pathways to provide new ideas for the intervention and treatment of NDDs. A comprehensive search of PubMed, Web of Science, and Google Scholar was conducted for articles on the intervention of anthraquinones in NDDs in the past 20 years. The collected information was then summarized and analyzed. Anthraquinones ameliorate NDDs through multiple mechanisms. They exhibit antioxidant and anti-inflammatory effects, protect mitochondria, and regulate microglial polarization. Furthermore, anthraquinones inhibit pyroptosis, apoptosis, tau phosphorylation, A\u03b2/\u03b1-synuclein aggregation, and acetylcholinesterase activity, while restoring metal homeostasis, activating estrogen receptors, modulating gut microbiota, increasing BDNF levels, and preserving blood-brain barrier permeability. More notably, these compounds play a neuroprotective role by mediating multiple signaling pathways and targets, including Nrf2, ERK1/2, PI3K/mTOR, ROS/TXNIP, SIRT1/PCG-1\u03b1, NLRP3, PI3K/Akt, MAPK, TLR4-NF\u03baB, CaM/CaMKIV, and Ca2+/EGFR/PLC\u03b3. The pleiotropic actions of anthraquinones highlight their potential as therapeutic candidates for NDDs, yet clinical validation remains essential. Future studies should emphasize rigorously designed clinical trials and optimized brain-targeted delivery platforms. This review consolidates current evidence to support their translational development.",
"41868372": "ID: 41868372\nTitle: Gut microbiota-derived EPA alleviates neuroinflammation associated with white matter injury by influencing H3K9ac/BDNF/TrkB pathway.\nAbstract: The objective of our investigation was to explore the features of gut microbiota dysbiosis and the concentrations of gut metabolites in relation to white matter injury (WMI). Furthermore, we sought to evaluate the influence of gut dysbiosis on neuroinflammation in WMI via intestinal metabolites, and its contribution to pathogenesis. A cerebral hypoxia-ischemia-induced WMI model was established in 3-day-old Sprague-Dawley rats. Liquid chromatography-mass spectrometry/gas chromatography-mass spectrometry analyses and 16S rRNA gene sequencing were undertaken to ascertain WMI biomarkers. Mechanistic experiments were used to analyse activation of the H3K9ac/BDNF/TrkB pathway and neuroinflammation. The analysis of 16S rRNA sequencing disclosed gut microbiota dysbiosis in WMI rats, quantified using linear discriminant analysis effect size. Overall, 341 differentially expressed metabolic markers between the WMI and Sham groups were discovered. The Kyoto Encyclopedia of Genes and Genomes network enhancement evaluation revealed significant downregulation of 20 metabolic processes in the WMI group, which is strongly related to changes in fecal microbial metabolites, and the synthesis process of unsaturated fatty acids was the most significant. Gut microbiota dysbiosis may influence WMI by downregulating metabolites such as eicosapentaenoic acid (EPA). Fecal microbiota transplantation increased EPA concentration in the brain tissue of WMI rats. Gut microbiota-derived EPA promoted H3K9ac and BDNF/TrkB expression and inhibited the transcription of pro-inflammatory TNF-\u03b1 and IL-1\u03b2 molecules. These EPA-mediated effects were reversed by TrkB inhibition. WMI induces gut dysbiosis involving down-regulation of unsaturated fatty acid synthesis. Fecal microbiota transplantation leads to increased levels of EPA. Gut microbiota-derived EPA increases levels of acetylated histone H3K9ac, causes activation of the BDNF/TrkB pathway, reduces neuroinflammation, and improves WMI-associated myelination disorders. It provides a basis for targeted treatment of white matter injury in the future.",

Microbial dysbiosis in the early stages of cognitive decline and Alzheimer's disease (AD) and can modulate the levels of microbe-derived metabolites (MDM), thought to contribute to neuroinflammation, blood\u2012brain barrier dysfunction, and neuronal degeneration. However, the precise role of MDM in this process, as well as their potential value as risk factors, remains poorly understood. Mass spectrometry platforms determined the serum concentration of 33 metabolites (13 tryptophan-related compounds, 15 bile acid compounds, 3 TMAO-related metabolites and 2 cresol metabolites) from cognitively healthy subjects, subjective cognitive impairment (SCI) participants and mild cognitive impairment (MCI) participants (n\u2009=\u200950 per group, matched for age, BMI and sex). Multiple linear regression and machine learning techniques were applied to identify a metabolite panel capable of classifying early cognitive decline. 16S rRNA amplicon sequencing was employed to identify bacterial taxa associated with these metabolic changes. Multiple linear regression modelling, adjusted for sex, BMI, age, albumin (for its role in metabolite transport), liver and kidney function, and background diet, identified key neuroprotective metabolites, namely choline, 5-hydroxyindole acetic acid, and indole propionic acid (IPA), as lower in SCI and MCI individuals compared to healthy controls. In contrast, the cytotoxic metabolite, indoxyl sulfate, and kynurenic acid were elevated. A random forest algorithm with multiclass classification further validated these findings, highlighting six metabolites (indoxyl sulfate, choline, 5-hydroxyindole acetic acid, IPA, kynurenic acid, and kynurenine) as classifiers of early cognitive decline, achieving an area under the curve (AUC) of 0.79. These findings suggest that MDM may serve as putative composite biomarkers of early cognitive decline, offering potential clinical relevance for metabolic risk stratification and supporting the future development of minimally invasive screening tools.",
"41903401": "ID: 41903401\nTitle: Short-chain fatty acids, neuroinflammation, and autism spectrum disorders: A mechanistic systematic review.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by social and communication deficits, repetitive behaviors, and cognitive alterations. Increasing evidence indicates that immune dysregulation, particularly neuroinflammation, is central to its pathophysiology. The gut-brain axis and microbial metabolites, especially short-chain fatty acids (SCFAs: butyrate, acetate, propionate), have emerged as potential modulators of these processes. SCFAs are absorbed from the gut and may modulate brain function via transporter-dependent mechanisms at the BBB, although evidence in ASD contexts remains limited, thereby allowing them to influence both peripheral and central immune responses. This qualitative systematic review included studies published between 2015 and 2025 addressing at least one of three links: (1) ASD and neuroinflammation, (2) ASD and SCFAs, and (3) SCFAs and neuroinflammation. Twenty studies met inclusion criteria and were analyzed. Findings indicate that SCFAs exert distinct effects: butyrate consistently shows neuroprotective and anti-inflammatory actions, acetate displays context-dependent dual effects, and propionate is mainly associated with detrimental outcomes, including social and cognitive impairments and elevated inflammatory markers. Overall, SCFAs may influence ASD pathophysiology through modulation of neuroinflammatory mechanisms, with effects depending on the specific SCFA, dosage, and context. Nutritional strategies that modulate SCFA production, such as dietary fiber enrichment, prebiotics, and probiotics, may offer feasible, non-invasive therapeutic approaches. However, clinical evidence remains limited and heterogeneous, highlighting the need for well-designed trials to determine optimal interventions targeting SCFAs in ASD.",

The gut-brain axis, influenced by diet and the gut microbiome, is increasingly recognized as a contributor to neurodegeneration. In this sub-analysis of a 10-week randomized dietary education intervention (NCT06121986), we examined how obesity modulates gut microbiome, metabolome, and cognitive responses in 31 adults aged 55-85, with or without mild cognitive impairment. Participants received education on either a Mediterranean Diet or a Modified Mediterranean-Ketogenic Diet. Analyses were stratified by baseline obesity (BMI\u2009\u226530 kg/m\u00b2). Individuals with obesity exhibited lower microbial alpha-diversity, higher Bacteroides, and lower Akkermansia and Christensenellaceae_R-7_group, along with poorer memory and executive function. Only in the obese group did fat loss correlate with improvements in episodic memory and cognitive flexibility. In contrast, increased fat mass was associated with improved memory in non-obese participants. Gains in skeletal muscle mass predicted cognitive improvement in adults aged\u2009\u226573. Changes in gut (acetate, propionate, lactate) and plasma (acetate, pyruvate, citric acid) metabolites were linked to cognitive and body composition outcomes. These exploratory findings highlight the gut-muscle-brain axis as a modifiable target to enhance cognitive health in aging populations.",

However, the role of 2'-FL in metabolic hypertension (MH) remains unclear. This study aimed to evaluate the effects of 2'-FL on MH and explore its underlying mechanisms. 2'-FL treatment (1000 mg/kg) reduced systolic blood pressure (SBP) by 16.6% and alleviated dyslipidemia, microglial activation, and neuroinflammation in MH mice. 2'-FL markedly increased short-chain fatty acids (SCFAs)-producing beneficial bacteria, e.g., Akkermansia and Bifidobacterium by 3.9-fold and 19.5-fold, accompanied by increased fecal acetate and butyrate. Notably, the benefits of 2'-FL for MH were transferable via fecal microbiota transplantation (FMT). Particularly, 2'-FL-mediated attenuation of vascular dysfunction was associated with the inhibition of the lipopolysaccharide/toll-like receptor 4 (LPS/TLR4) signaling, a protective effect that could be transferred via FMT. The antihypertensive and metabolic benefits of 2'-FL in mice were accompanied by gut-brain axis modulation. These findings suggest that 2'-FL represents a promising dietary strategy for preventing hypertension-associated complications.",

Activation of hippocampal AMP-activated protein kinase (AMPK) in ulcerative colitis mice with disrupted gut microbiota balance produces antidepressant effects. However, the relationship between hippocampal AMPK and antibiotic treatment (ABX)-induced depression-like behavior remains unclear. Therefore, we aimed to investigate whether 5-aminoimidazole-4-carboxamide 1-\u03b2-d-ribofuranoside (AICAR), an AMPK activator, is associated with the prevention of ABX-induced depression-like behaviors. ABX mice exhibited depression-like behaviors, as evidenced by prolonged immobility and reduced sucrose preference. In the hippocampus of the ABX mice, Iba1 and pro-inflammatory microglial markers were upregulated, whereas brain-derived neurotrophic factor (BDNF), CD206, arginase-1, and interleukin-10 were downregulated. Additionally, levels of AMPK phosphorylation, cAMP response element binding protein (CREB), and tropomyosin-related kinase B (TrkB) were decreased. AICAR administration attenuated these behavioral and molecular alterations. Phosphorylated AMPK was colocalized with the neuronal marker-NeuN-and microglial marker-Iba1. AICAR ameliorated the reduction in hippocampal neuron proliferation and survival and reduced microglial activation-associated morphological changes in the hippocampus. These findings suggest that AICAR administration is associated with antidepressant-like effects, potentially involving enhanced neurogenesis and attenuation of neuroinflammation in the hippocampus of ABX mice. Together, this study highlights the significance of hippocampal AMPK phosphorylation in depression associated with gut microbiota alterations, and suggests a potential target for therapeutic interventions.",

The microbiota-gut-brain axis (MGBA) plays a key role, with short-chain fatty acids (SCFAs) emerging as potential therapeutic agents. This study explores the impact of SCFAs, particularly acetate, in mitigating NEC-related brain injury. A NEC rat model was established via overfeeding, hypoxia, and asphyxia. Intestinal injury, SCFA levels, systemic inflammation, and neuroinflammation were assessed through histology, gas chromatography-mass spectrometry, ELISA, and Western blotting. Cognitive function was evaluated using the Morris water maze test. NEC rats exhibited significantly lower levels of intestinal SCFAs, particularly acetate, compared to control rats. These reductions were accompanied by systemic inflammation, neuroinflammation and cognitive deficits. Supplementation with sodium acetate mitigated both intestinal and neuroinflammatory responses and improved cognitive function. Acetate depletion contributes to NEC-associated brain injury, and early acetate supplementation may offer a promising therapeutic strategy to mitigate intestinal damage, neuroinflammation, and cognitive impairment. Identifies acetate depletion as a key factor in NEC-related brain injury. Demonstrates that sodium acetate supplementation mitigates neuroinflammation and cognitive impairment. Expands understanding of the microbiota-gut-brain axis in NEC pathophysiology. Highlights SCFAs as potential therapeutic agents for NEC-related complications. Suggests a novel intervention strategy to improve neurodevelopmental outcomes in preterm infants.",

However, its antidepressant effect and underlying mechanisms remain insufficiently characterized. This study aims to comprehensively evaluate the antidepressant effect of ABS in a rat model, and to elucidate the underlying mechanism. Chronic unpredictable mild stress (CUMS) induced depressive rats were used to evaluate the antidepressant effect of ABS. Histopathological alterations in the hippocampus and colonic mucosa were examined using Nissl and H&E staining. Microglial activation was evaluated by Iba-1 immunohistochemical staining. Gut microbiota composition and metabolic profiles were analyzed using 16S rRNA sequencing and untargeted metabolomics. Differential gene expression and pathway regulation were investigated by transcriptomics and confirmed by Western Blot (WB). ABS significantly ameliorated depressive-like behaviors and elevated dopamine and 5-Hydroxytryptamine levels in cortical regions. Furthermore, ABS mitigated hippocampal neuronal damage, suppressed microglial overactivation and reduced oxidative stress in the cortex. 16S rRNA sequencing analysis showed that ABS exerted antidepressant effects via modulation of the \"microbiota-gut-brain\" axis, particularly by altering intestinal microbiota composition, enhancing gut function, and suppressing HPA axis hyperactivity. Metabolomics revealed that ABS corrected metabolic disturbances, and alleviated inflammation-related metabolic disturbances, while transcriptomics indicated regulation of the Npas4-BDNF-PI3K/AKT signaling pathway, which was further confirmed by WB. ABS significantly ameliorated depression in a CUMS rat model, primarily through coordinated regulation of gut microbiota, metabolic homeostasis, and the Npas4-BDNF-PI3K/AKT signaling pathway, providing integrative mechanistic insights into its antidepressant effects.",

However, the underlying mechanisms of these symptoms remain to be fully elucidated. This study investigated the effects and mechanisms of a 20% ethanolic extract of Petasites japonicus leaves (EPJ) on dextran sulfate sodium (DSS)-induced colitis and depression-like behaviors. The physiological compounds identified in the EPJ were citric acid, chlorogenic acid, caffeic acid, fukinolic acid, 3,5-dicaffeoylquinic acid, quercetin 3-O-\u03b2-D-glucose-6\u2033-acetate, 4,5-dicaffeoylquinic acid, kaempferol-3-O-(6\u2033-acetyl)-\u03b2-glucopyranoside, and pedunculoside. EPJ significantly alleviated DSS-induced colitis, as evidenced by improvements in body weight loss (87.41% vs. 76.02% in the DSS group), colon length (5.75 vs. 4.34 cm), intestinal permeability (52.80 vs. 163.01 \u03bcg/mL), and myeloperoxidase (MPO) activity (0.24 vs. 0.67 U/mg) (p < 0.05). Histological analysis further confirmed recovery of goblet cells and attenuation of muscle layer thickening. EPJ also reversed DSS-induced gut microbiota dysbiosis and contributed to the restoration of microbial homeostasis. Behavioral assessments showed that EPJ effectively ameliorated depression-like behaviors. EPJ improved antioxidant systems in colon and brain tissues by modulating malondialdehyde (MDA) levels and reduced glutathione (GSH) and superoxide dismutase (SOD) activity. EPJ further upregulated tight junction protein expression and suppressed TLR4/NF-\u03baB inflammatory pathway activation in both colon and brain tissues. Moreover, EPJ modulated serum stress-related hormones, normalized hypothalamic-pituitary-adrenal (HPA) axis dysregulation, regulated the BDNF/TrkB signaling pathway, and modulated tryptophan-kynurenine metabolism. Collectively, these findings suggest that EPJ exerts protective effects against DSS-induced colitis and depression-like behaviors.",

However, the exact mechanisms underlying PND are not fully understood. The lung-brain axis has recently been recognized as an important pathway in neurodegenerative diseases such as Alzheimer's disease (AD). Given that PND shares pathological features with AD, such as amyloid-\u03b2 (A\u03b2) accumulation, the lung-brain axis may also represent a plausible mechanistic contributor to PND. Furthermore, elderly surgical patients often receive inhalation anesthetics and undergo mechanical ventilation during general anesthesia, which directly affect the lungs and may alter the pulmonary microenvironment. Therefore, we hypothesize that the lung-brain axis plays a role in the development of PND. In this article, we discuss potential mechanisms by which surgery and anesthesia-especially inhalation anesthetics and mechanical ventilation-may influence cognitive function via the lung-brain axis. Potential mechanisms include changes in the pulmonary microbiota, secretion of brain-derived neurotrophic factor, and lung-derived inflammatory responses. These pathways may disrupt the blood-brain barrier, promote neuroinflammation, and exacerbate A\u03b2 deposition, ultimately leading to cognitive impairment. Exploring the role of the lung-brain axis could provide new insights into PND pathophysiology and reveal potential targets for prevention and treatment of PND by targeting pulmonary-mediated cascades.",

Here, we delineate a gut-to-CNS axis for pain modulation, demonstrating that an acetate-producing diet alleviates reserpine-induced-fibromyalgia in a rodent model. We show that diet rich in acetylated high-amylose maize starch shifts the gut microbiome to favor acetate-producing bacteria, increasing systemic acetate levels and reducing pain hypersensitivity. This is associated with reduced spinal microglia activation and anti-inflammatory cytokine gene expression, with elevated IL-10 mRNA in the DRG and IL-10, IL-2, and IL-6 in the spinal cord. Electrophysiologically, we observe reduced hyperexcitability in the dorsal horn and increased inhibitory activity. The mechanism driving this change involves reduced prostaglandin-E2 (PGE2)-mediated suppression of glycinergic inhibition, a direct consequence of maintaining microglia in quiescent state. These findings link dietary metabolites to reduced fibromyalgia-like pathology and identify targeted nutrition as a potential disease-modifying therapy for chronic pain.",
"42021550": "ID: 42021550\nTitle: Acupuncture: A Promising Non-Pharmacological Approach to Parkinson's Disease Management.\nAbstract: This review aims to elucidate the molecular mechanisms underlying the neuroprotective effects of acupuncture in preclinical models of Parkinson's disease (PD). In PD animal models, acupuncture inhibits oxidative stress by upregulating nuclear factor erythroid 2-related factor 2 (Nrf2)/antioxidant response element (ARE), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) while reducing malondialdehyde (MDA) and lipid peroxidation. It regulates autophagy either independently of mammalian target of rapamycin (mTOR) or via mTOR activation, promoting alpha-synuclein (\u03b1-synuclein) clearance. Acupuncture also suppresses apoptosis (modulating Bcl-2-associated X protein (Bax)/B-cell lymphoma 2 (Bcl-2)) and pyroptosis (inhibiting NLR family pyrin domain containing 3 (NLRP3) inflammasome and gasdermin D (GSDMD)). It enhances neurogenesis through brain-derived neurotrophic factor (BDNF)/extracellular signal-regulated kinase (ERK)/cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB) and glial cell line-derived neurotrophic factor (GDNF) signaling, promoting neural stem cell proliferation and differentiation. Furthermore, acupuncture reduces neuroinflammation by decreasing microglial activation, cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF-\u03b1), and interleukin-1 beta (IL-1\u03b2). It also modulates gut microbiota composition (e.g., increasing butyrate-producing bacteria like Butyricimonas and reducing pro-inflammatory Erysipelotrichaceae and Bacteroides) and influences lipid metabolism, thereby mitigating dopaminergic neuron loss and motor deficits. Preclinical evidence demonstrates that acupuncture exerts multi-target neuroprotective effects against PD through pathways involving oxidative stress, autophagy, apoptosis/pyroptosis, neurogenesis, neuroinflammation, and gut microbiota-lipid metabolism crosstalk. However, limitations include a focus on preventive rather than reversal effects, lack of long-term efficacy data, and heterogeneity in acupoint selection. Further mechanistic and standardization studies are warranted.",

Growing evidence suggests that gut microbiota-derived metabolites, including short-chain fatty acids (SCFAs) and tryptophan-related indole compounds, modulate neuroinflammation and cerebrovascular vulnerability. However, their temporal dynamics and clinical relevance after aSAH are insufficiently characterized. In this prospective observational study, 80 consecutive patients with aSAH were enrolled at a tertiary neurocritical care center. Serum concentrations of SCFAs (propionic, butyric, isobutyric, valeric, isovaleric, caproic acids) and tryptophan-derived metabolites (tryptophan, indole-3-propionic acid [IPA], indole-3-acetic acid, indole-3-lactic acid) were quantified using LC-MS on Day 1 and Day 9 after hemorrhage. Functional outcome at 3\u202fmonths was assessed using the modified Rankin Scale (mRS), and DCI was diagnosed according to consensus criteria. Associations were analyzed using non-parametric statistics, ROC analyses, and multivariable logistic regression adjusted for established clinical confounders. Patients with unfavorable 3-month outcomes (mRS 4-6) showed significantly lower Day 1 levels of propionic, isobutyric, and isovaleric acids, persistently reduced tryptophan at both time points, and markedly lower IPA concentrations on Day 9. DCI was associated with reduced tryptophan and propionic acid levels on both days and a pronounced decrease in IPA on Day 9. Tryptophan and propionic acid demonstrated excellent discriminative performance for outcome and DCI (AUCs up to 0.99). In multivariable models, low Day 1 propionic acid and low Day 9 IPA independently predicted unfavorable outcome, while Day 9 tryptophan, IPA, and propionic acid independently predicted DCI. Distinct temporal alterations in gut microbiota-derived metabolites after aSAH are strongly associated with functional outcome and DCI. SCFAs and tryptophan-related metabolites-particularly propionic acid, tryptophan, and IPA-emerge as promising biomarkers and potential mechanistic mediators in secondary brain injury after aSAH.",
"42036577": "ID: 42036577\nTitle: Chronic Inflammation and Neuroprogression in the Pathophysiology in Major Depression.\nAbstract: Major depressive disorder (MDD) results from interactions between genetic and environmental factors, contributing to neuroinflammation and neurodegeneration. Chronic stress, poor diet, and environmental toxins exacerbate inflammatory responses, leading to neuronal dysfunction and disease progression. Stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis promotes a pro-inflammatory state, impairing neuroplasticity and cognition. Likewise, unhealthy diets disrupt gut microbiota, increasing systemic inflammation, while anti-inflammatory diets offer neuroprotection. Exposure to air pollutants and heavy metals induces oxidative stress and mitochondrial dysfunction, further worsening neuroinflammation. Genetic predisposition influences inflammatory responses, with polymorphisms in interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-\u03b1), and brain-derived neurotrophic factor (BDNF), affecting MDD susceptibility and neuronal resilience. Given the inflammatory basis of MDD, treatment should extend beyond traditional monoaminergic therapies. Emerging approaches, including ketamine and monoclonal antibodies targeting inflammatory pathways, show promise. Lifestyle interventions such as physical exercise and anti-inflammatory diets may complement pharmacological treatments by reducing neuroinflammation and promoting neuronal health. This chapter explores the complex interactions between genetic and environmental factors in MDD, emphasizing their role in neuroinflammation and highlighting potential therapeutic strategies.",

Rats were exposed to hypobaric hypoxia (simulated 5000 m) for 14 days. Gut microbiota and serum short-chain fatty acids (SCFAs) were analyzed via 16S rRNA sequencing and GC-MS. Rats were then infected with Streptococcus pneumoniae and treated with FMT. Lung inflammation, NLRP3 inflammasome activity, cytokines, bacterial load, and secretory IgA (sIgA) were assessed. Hypobaric hypoxia triggered gut dysbiosis, marked by reduced abundance of Firmicutes D and Lactobacillus, elevated Bacteroidota, and decreased SCFA levels..FMT restored microbiota composition, increased acetic and butyric acid levels, and attenuated lung inflammation. FMT also enhanced NLRP3 inflammasome activation (NLRP3, ASC, Caspase-1), elevated IL-1\u03b2, IL-6, and TNF-\u03b1 in BALF, reduced bacterial colonies, and increased airway sIgA in infected rats. FMT alleviates hypobaric hypoxia-aggravated respiratory infection by restoring gut microbiota, modulating SCFAs, and enhancing NLRP3-mediated mucosal immunity, highlighting the gut-lung axis as a therapeutic target.",

Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the \"Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Function\" axis. Consistent physical exercise alters the gut microbiota, enhancing Short-Chain Fatty Acid (SCFA)-producing populations, which is associated with markedly elevated bioavailability of key metabolites (acetate, propionate, and butyrate). Rather than detailing exhaustive molecular pathways here, we emphasize that these SCFAs facilitate gut-brain communication through multiple synergistic routes, including receptor-mediated neuroendocrine signaling, epigenetic modulation of neuroplasticity, and the attenuation of systemic neuroinflammation. Current human observational and interventional data strongly support an associative link between exercise-induced SCFA fluctuations and improved mental health outcomes. Crucially, we propose the novel \"Exercise \u00d7 Fiber Synergy\" hypothesis: exercise primes the intestinal ecological niche for efficient substrate-utilizing bacteria, while adequate fermentable dietary fiber provides the necessary raw materials. Synergistically, this combination optimizes SCFA production to maximize cognitive and emotional benefits. To transition this framework into clinical practice, future research must prioritize 2 \u00d7 2 factorial designs (Exercise \u00d7 Fiber) with dynamic kinetic measurements, paving the way for microbial phenotype-oriented precision exercise and personalized nutritional interventions to enhance public mental health.",
"42062245": "ID: 42062245\nTitle: From gut to brain: effects of fecal microbiota transplants from humans to rats on hippocampal gene regulation - a study on anorexia nervosa.\nAbstract: Fecal microbiota transplantation (FMT) has emerged as a novel approach for understanding anorexia nervosa (AN), a complex eating disorder characterized by severe underweight, fear of weight gain and distorted body image. Patients with AN show alterations in the gut microbiome, brain structure, and inflammatory processes, indicating the importance of the microbiome\u2012gut\u2012brain axis in AN pathology. This study aimed to investigate whether FMT from patients with AN into antibiotic-treated rats could transfer a phenotype associated with the disease inducing AN-like symptoms and hippocampal alterations. Female Wistar rats received antibiotics followed by FMT from healthy controls, patients with AN, or water. Gut microbiota effects were assessed through 16S rRNA gene sequencing, alongside post-mortem analyses of glial cells, neurogenesis markers, and inflammatory markers. The results revealed dysregulated microbial diversity after antibiotic treatment, which was partially restored after FMT. Successful transfer of human bacterial species was observed, but AN-like symptoms and changes in glial/neuronal counts were not detected. Notably, a decrease in hippocampal Bdnf expression was detected in the antibiotic control group, which was reversed by healthy control stool transplantation but not in the AN-transplanted group. Similar patterns were observed for neuroinflammation and Mki67, a marker of cell neogenesis. These findings suggest potential links between microbial changes, neuroinflammation and neuroplasticity in the hippocampus with the potential to correct deficits with FMT. Future studies should extend these findings by exploring the combination of FMT and starvation phases to better understand the roles of specific microbial populations in neuroinflammatory processes and, ultimately, clinical outcomes in AN.",

Histone deacetylase 3 (HDAC3), a negative regulator of memory and synaptic plasticity, has been implicated in neurodegenerative conditions, but its role remains underexplored in psychosis. Here, we hypothesized that aberrant HDAC3 activity contributes to hippocampal dysfunction and learning deficits in schizophrenia. Pregnant SD rats were administered methylazoxymethanol (MAM; 20\u202fmg/kg) and vehicle on GD 17. We characterized the pharmacokinetic profile of selective HDAC3 inhibitor, SP108, to ensure adequate BBB penetration and systemic exposure. Next, adult male offspring were administered SP108 (25\u202fmg/kg, i.p.) and vehicle every day for 3 weeks, followed by behavioral analysis. The MAM-exposed group showed schizophrenia-like behavioral patterns with increased hippocampal HDAC3 expression and activity. HDAC3 inhibitor treatment selectively ameliorated avoidance learning and MK801-induced hyperlocomotion. At the molecular level, HDAC3 inhibition elevated hippocampal H3K9 acetylation and increased the expression of synaptic plasticity markers BDNF and PSD95. To establish a neurodevelopmental link, HDAC3 knockdown was performed in differentiating neurons from mouse embryonic stem cells (mESCs) exposed to MAM at the early differentiating phase in vitro. HDAC3 knockdown in MAM-exposed differentiating neurons enhanced MAP2 intensity and neurite length with improved levels of MAP2, NeuN, TUBB3 (neuronal differentiation and maturation markers), BDNF, and PSD95 (neuroplasticity markers). Collectively, these findings identify HDAC3 as an important regulator of hippocampal dysfunction and cognitive impairment in a schizophrenia-like preclinical model, highlighting its potential to augment the therapeutic outcomes beyond current antipsychotic treatments.",

However, the mechanisms underlying their induction of emotional disorders remain poorly understood. In particular, intervention-oriented and functionally validated strategies for prevention and control are still lacking. To address this, we conducted a 28-day repeated oral exposure study in mice using a gradient of polystyrene nanoplastics (PS-NPs; 2, 10, and 50\u00a0mg/kg/day) spanning environmentally relevant doses, systematically assessing impacts along the microbiota-gut-brain axis. Our results showed that PS-NP exposure induced dose-dependent anxiety- and depression-like behaviors, with fluorescence tracing revealing predominant gut accumulation and limited brain distribution. Mechanistically, exposure induced gut microbiota dysbiosis, intestinal barrier impairment, and lipopolysaccharide translocation, ultimately leading to systemic inflammation and neuroinflammation. Serum biochemical analysis showed that gut dysbiosis initiates host tryptophan metabolism toward the kynurenine pathway by triggering inflammation and subsequent indoleamine 2,3-dioxygenase 1(IDO1) activation. Consistently, hippocampal transcriptomic and biochemical analyses confirmed decreased 5-HT levels and suppression of the downstream 5-HT1A-cAMP-PKA-CREB-BDNF neurotrophic cascade, demonstrating comprehensive serotonergic disruption from substrate depletion to receptor dysfunction. Notably, the prebiotic galacto-oligosaccharides (GOS) restored intestinal homeostasis and ameliorated these anxiety- and depression-like behavioral and metabolic deficits, exerting protective effects by counteracting the above pathway. Our work delivers a from-mechanism-to-solution understanding: it deciphers how microplastics disrupt the gut-brain axis to cause neurotoxicity and identifies GOS maintenance of intestinal health as a key mitigative strategy against plastic pollution risks. Therefore, maintaining intestinal health, particularly through dietary GOS, represents a viable strategy to mitigate the neurotoxicity induced by plastic pollution.",

With limited disease-modifying pharmacotherapies, lifestyle interventions have emerged as compelling, evidence-based avenues for prevention and early management. This review integrates mechanistic, translational, and clinical insights on major modifiable behaviours, physical activity, diet, intermittent fasting, sleep regulation, and gut-microbiome-based approaches that collectively shape cognitive ageing. Aerobic, anaerobic, and resistance exercises exert neuroprotective effects by activating BDNF-TrkB signalling, enhancing hippocampal neurogenesis, improving synaptic plasticity, and stimulating peripheral myokines (CTSB, IGF-1, GPLD1) that cross the blood-brain barrier to support neuronal resilience. Dietary interventions such as the Mediterranean, Mediterranean- DASH Intervention for Neurodegenerative Delay (MIND), and ketogenic diets mitigate AD pathology by reducing oxidative stress, inhibiting A\u03b2 deposition, improving mitochondrial efficiency, and modulating APOE4-linked metabolic vulnerability. Intermittent fasting induces a metabolic shift toward ketone utilisation, activates autophagy pathways (AMPK, SIRT3, Nrf2), remodels the gut microbiome, and promotes angiogenesis through GDF11 signalling. The gut-brain axis contributes to cognitive health through microbial metabolites, such as Short-Chain Fatty Acids (SCFAs), tryptophan derivatives, modulation of neuroinflammation, and enhanced neuronal survival. Meanwhile, sleep quality, particularly slow-wave sleep, optimises glymphatic clearance and prevents the pathological accumulation of A\u03b2 and tau. Collectively, the evidence suggests that multidomain lifestyle approaches offer synergistic benefits that exceed those of individual interventions, representing promising strategies for delaying cognitive decline. However, gaps remain regarding dose-response relationships, personalised protocols for APOE4 carriers, and long-term validation in diverse populations. Strengthening these research directions is crucial for integrating lifestyle medicine into preventive neurology and public health frameworks.",

Therefore, butyrylated starch acts as a butyrate carrier and resistant starch to produce butyric acid, potentially improving cognitive dysfunction. In the d-galactose-induced aging mice model, BNMS2 effectively improved cognitive dysfunction and outperformed sodium butyrate and high-amylose maize starch. BNMS2 ameliorated cognitive behavior and brain histopathology, decreased GFAP, IBA-1, A\u03b2, AChE, MDA, IL-6, IL-1\u03b2, and TNF-\u03b1 levels, and increased BDNF, PSD-5, GSH-Px, and SOD levels to mitigate neuronal damage, oxidative stress, and inflammation. BNMS2 also produced abundant butyric acid, enhanced the abundance of beneficial bacteria (Alistipes, Parasutterella, Parabacteroides, Lachnospiraceae_UCG-006, Muribaculum) and molecular transport and signaling functions, suppressed d-galactose-induced harmful bacteria proliferation and galactose metabolism, and increased dopamine, glutamic acid, \u03b3-aminobutyric acid, glutamine, tryptophan, N-acetylneuraminic acid, and nicotinamide levels.

Here, we investigated the contribution of the pulmonary microbiota and its metabolites to anxiety-like behavior in an ovalbumin-induced asthma mouse model. Behavioral testing and resting-state functional magnetic resonance imaging revealed anxiety-like phenotypes and altered hippocampal function in a subset of asthmatic mice that were susceptible to anxiety-like behavior. These mice exhibited hippocampal neuroinflammation and neuronal damage, accompanied by dysbiosis of the pulmonary microbiota. Intratracheal transplantation of lung microbiota from anxiety-susceptible donors induced similar behavioral changes in recipient mice, indicating a causal role of the pulmonary microbiota. Untargeted metabolomics identified formononetin as a candidate metabolite positively correlated with the relative abundance of Acidobacteria. Intratracheal administration of formononetin alleviated anxiety-like behaviors, reduced hippocampal inflammation and injury, and restored hippocampal BDNF/TrkB signaling. However, these effects were abolished by the TrkB antagonist ANA-12. Transcriptomic and immunofluorescence analyses suggested that formononetin acts through modulation of hippocampal microglia. In vitro and small RNA sequencing analyses further demonstrated that formononetin promotes BDNF production by downregulating miR-1912-3p, thereby relieving its translational repression in microglia. Together, these findings reveal a lung-brain axis in which a pulmonary microbiota-associated metabolite modulates microglial function to alleviate asthma-related anxiety.",

To explore this, a chronic unpredictable mild stress (CUMS) rat model was established to evaluate the potential antidepressant effects of Weizmannia coagulans BC99. Behavioral assessments included the sucrose preference test (SPT), forced swim test (FST), tail suspension test (TST), and open field test (OFT). In addition, 16S rRNA sequencing, serum metabolomics, and short-chain fatty acid (SCFA) profiling were performed. Levels of inflammatory cytokines (IL-1\u03b2, IL-6, IL-4, and LPS) and brain-derived neurotrophic factor (BDNF) were measured in serum, hippocampus, and colon by ELISA. An independent sodium butyrate supplementation experiment was conducted to test functional sufficiency, and hippocampal BDNF/TrkB/CREB signaling was assessed by Western blotting. Treatment with BC99 was associated with alleviation of CUMS-induced depressive-like behaviors, increased butyrate levels, reduced neuroinflammation (IL-1\u03b2, IL-6, LPS, and IL-4), and restored hippocampal BDNF levels. BC99 also enriched butyrate-producing bacterial taxa (e.g., Lactobacillus, Bifidobacterium, Faecalibaculum) and normalized tryptophan and sphingolipid metabolism. Notably, sodium butyrate alone recapitulated several of the behavioral and anti-inflammatory effects observed with BC99 and, as shown by Western blot, partially restored hippocampal BDNF/TrkB/CREB signaling, which was impaired in CUMS rats. Together, these findings suggest that butyrate may be associated with the antidepressant effects of W. coagulans BC99, potentially acting through suppression of neuroinflammation and activation of the BDNF pathway. Our results support further investigation of butyrate-enhancing strategies as a nutritional approach for depression.",

Acupuncture, a multi-target holistic non-pharmacological intervention, shows unique clinical advantages. This review provides the first systematic synthesis of the central neurobiological mechanisms underlying acupuncture's therapeutic effects on PSD. The identified mechanisms include promoting neuroplasticity via the BDNF/TrkB pathway and rebalancing neurotransmitter systems (monoamines and glutamate/GABA). Additionally, acupuncture inhibits microglial activation and TLR4/NF-\u03baB/NLRP3-driven neuroinflammation, restores mitochondrial homeostasis through AMPK-dependent autophagy, and modulates the gut microbiota-brain axis. Together, these findings elucidate the \"multi-target, network-based\" characteristics of acupuncture from a modern scientific perspective, providing a scientific basis for traditional Chinese acupuncture principles. By integrating recent mechanistic advances, this review addresses literature gaps and offers a theoretical foundation for optimizing clinical strategies, promoting mechanism-driven personalized interventions, and bridging traditional Chinese medicine with contemporary neuroscience.",
"42149101": "ID: 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.",

Increasing evidence implicates neuroinflammation, oxidative stress, and dysregulation of neurotrophic and neurotransmitter systems as central mechanisms driving these conditions. Flavonoids, a structurally diverse class of plant-derived polyphenolic compounds abundantly found in fruits, vegetables, tea, and other dietary sources, have emerged as promising modulators of these pathophysiological pathways. This narrative review synthesizes current preclinical and clinical evidence on the role of flavonoids and related natural compounds in modulating neuroinflammation and affective disorders. We describe the major flavonoid subclasses-flavones, flavonols, isoflavones, anthocyanins, flavanones, and flavan-3-ols-and analyze their mechanisms of action, including inhibition of the NF-\u03baB/NLRP3 axis, reduction in pro-inflammatory cytokines, attenuation of oxidative stress via Nrf2 pathway activation, modulation of monoaminergic and GABAergic neurotransmission, promotion of Brain-Derived Neurotrophic Factor (BDNF)-mediated neuroplasticity, and regulation of the microbiota-gut-brain axis. Preclinical studies consistently demonstrate anxiolytic and antidepressant effects for compounds such as quercetin, luteolin, apigenin, and chrysin; however, clinical evidence remains limited and methodologically heterogeneous. Future research should prioritize bioavailability-enhanced formulations, standardized clinical trials, and biomarker-guided stratification to fully establish the therapeutic potential of flavonoids in affective disorders.",

Seabuckthorn pomace bound polyphenols (SBP), as key bioactives from seabuckthorn, mainly contain ellagic acid, kaempferol, rutin, salvianolic acid A, and isorhamnetin. Chronic sleep deprivation (SD) leads gut microbiota dysbiosis and systemic inflammation, impairs neuronal and synaptic structural integrity, induces cognitive dysfunction, and increases the risk of neurodegenerative diseases. However, the ameliorative effects and underlying molecular mechanisms of SBP against SD-induced cognitive impairment remain unclear. The study investigated the improving effects and underlying mechanisms of dietary SBP supplementation on cognitive injury induced by chronic SD in mice. Behavioral results showed that 45\u00a0mg\u00b7kg-1\u00b7d-1 SBP significantly alleviated cognitive dysfunction in SD mice. Meanwhile, SBP ameliorated intestinal inflammation, gut microbial imbalance and tyrosine metabolism disorder, and markedly enriched beneficial bacteria including Bifidobacterium, Lactobacillus and Ligilactobacillus, with increased homovanillic acid (HVA) levels in feces, serum and brain. Furthermore, SBP attenuated SD-induced neuronal and synaptic damage and upregulated synaptic proteins SYN1 and PSD-95, which was associated with HVA-mediated inhibition of LC3/P62 autophagy pathway and activation of BDNF/TrKB pathway.

As the pathogenesis remains poorly understood, the currently available treatment regimens are mostly symptomatic therapies with little satisfactory curative effect. The emerging paradigm of gut-brain axis has highlighted gut dysbiosis as a key etiological factor to elicit neuro-inflammation and jeopardize the central nervous system homeostasis. In this study, we evaluated the ameliorating effects of flaxseed lignans on the gut microbiome to regain the gut micro-environmental functionality and alleviate MDD. The lignans significantly mitigated the severity of disease and markedly altered the gut microbiota structure in the participants. In the MDD mouse model, the lignans reversed the experimental depression-like behaviors, repaired neural and gut damage and restored barrier integrity. Of great significance, the lignans elevated the levels of 5-hydroxytryptamine (5-HT), brain-derived neurotrophic factor (BDNF) and \u03b3-aminobutyric acid (GABA), and markedly attenuated microglial and systemic inflammation. Mechanistically, the lignans inhibited the IL-17/AP-1/NF-\u03baB axis through direct interaction with the Fos protein. In the BV-2 cells, the lignan enterolactone reduced levels of nitric oxide and pro-inflammatory cytokines, further validating the anti-inflammatory mechanism of the lignans. Together, these findings demonstrate that lignans exert potent antidepressant effects by modulating the gut-brain axis and resolving neuro-inflammation, providing useful information for the development of novel therapeutic strategies for MDD prevention and treatment.",
"42217976": "ID: 42217976\nTitle: Neurodegeneration and neuroprotection in retinal detachment.\nAbstract: Retinal detachment (RD) occurs when the neurosensory retina separates from the retinal pigment epithelium (RPE). The most frequent type, rhegmatogenous retinal detachment (RRD), is caused by full-thickness retinal breaks that typically arise from vitreoretinal traction during posterior vitreous detachment. These breaks permit fluid to enter the subretinal space, leading to acute and often severe visual loss. Key risk factors include aging, myopia, pseudophakia, and the occurrence of posterior vitreous detachment. RRD constitutes a surgical emergency. Modern vitreoretinal procedures achieve high rates of anatomic reattachment; however, functional recovery remains highly variable. A major reason is that photoreceptor loss begins rapidly after detachment, driven by apoptosis, necroptosis, and inflammatory pathways, leading to irreversible damage even after successful surgical repair. This has stimulated interest in adjunctive neuroprotective strategies. Experimental and early clinical data suggest that repurposed agents such as tauroursodeoxycholic acid (TUDCA), ursodeoxycholic acid (UDCA), and iron chelators may preserve photoreceptor integrity. A multicenter randomized controlled trial (NCT06294847) is currently investigating oral UDCA in patients with macula-off RRD. Given that photoreceptor degeneration is a major determinant of limited visual recovery, combining surgery with neuroprotective therapies targeting cell-survival pathways may represent an important advance in improving postoperative visual outcomes.",
"42217987": "ID: 42217987\nTitle: Neuroprotective strategies for retinal disease.\nAbstract: Neurodegenerative diseases of the retina result from diverse insults, including genetic mutations, metabolic deficiencies, vascular compromise, and inflammatory injury. These processes converge on dysfunction of the neurovascular unit, where neurons, glia, and vascular cells cooperate to maintain retinal health. Thus, neuroprotection must be considered in a broader context that incorporates support of glial and vascular elements in addition to neurons. In this chapter, we review both classical and emerging neuroprotective strategies in retinal disease. We summarize preclinical and clinical studies of trophic factor-based approaches, including ciliary neurotrophic factor (CNTF), brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), neurotrophin-3 (NT-3), fibroblast growth factor 2 (FGF2), insulin-like growth factor-1 (IGF-1), and transforming growth factor-\u03b2 (TGF-\u03b2), outlining mechanisms, efficacy, limitations, and safety. We also highlight nonclassical agents such as mesencephalic astrocyte-derived neurotrophic factor (MANF) and the lipid mediator erucamide, which act through distinct pathways to modulate stress responses and neurovascular stability. Additional approaches, including stem cell-based therapies, extracellular vesicles, metabolic supplementation, and lifestyle interventions, are discussed. Finally, we emphasize the importance of human-derived models such as retinal explants and organoids to overcome translational barriers. Collectively, these studies suggest that multimodal strategies may offer meaningful neuroprotection and preserve vision in progressive retinal disease.",

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.",

Extracellular magnesium (Mg2+) blocks NMDA receptors in a voltage-dependent manner, offering potential neuroprotection. However, the optimal Mg2+ concentrations and timing for effective intervention remain poorly defined. We developed a conductance-based computational model of an RGC incorporating Hodgkin-Huxley dynamics, AMPA and NMDA receptor-mediated synaptic transmission, and intracellular calcium dynamics. We systematically varied Mg2+ concentration (0.2-2.5 mM) and stimulation frequency (10-100 Hz) to identify therapeutic windows balancing neuroprotection with function preservation. At physiological frequencies (10-60 Hz), elevated Mg2+ reduced calcium (Ca2+) accumulation by 50-85% without affecting spike output. At excitotoxic frequencies (80 Hz), a narrow therapeutic window of 1.6-2.0 mM was identified, lying within a broader 1.4-2.0 mM spike-loss plateau (20% loss), where calcium additionally fell below the toxicity threshold while spike output was preserved. Intervention timing analysis revealed that Mg2+ protection efficacy is maximal with pre-treatment or immediate intervention (100%), and declines steeply with delay-reflecting the rapid early rise in Ca2+ rather than a fixed biological deadline (\u226550% protection requires intervention within 0.2 s in our abrupt-onset protocol; \u223c11% by 0.5 s). Re-analysis in terms of normalized Ca2+ progress revealed that the critical constraint for \u226550% protection is intervention before \u223c35% of peak Ca2+ accumulation-a state-based threshold reflecting relative phase sensitivity that generalizes across timescales. Sensitivity analyses confirmed robustness of the therapeutic window across physiologically plausible parameter ranges, and numerical validation demonstrated accuracy of the computational approach. These findings demonstrate that Mg2+-mediated neuroprotection is highly dependent on both concentration and timing, with implications for therapeutic strategies targeting glutamate excitotoxicity in glaucoma and retinal ischemia.",

Microbiome-derived metabolites have been increasingly associated with disease onset, progression, and therapeutic targets in neurodegenerative disorders. Exploring the diagnostic and therapeutic implications of gut microbiome-derived biomarkers is critical to advancing our understanding and management of neurodegeneration. We systematically reviewed both clinical and preclinical studies published from 2010 to 2025. Studies examining gut microbiota composition, microbial-derived metabolites, or therapeutic interventions targeting the gut microbiome were included. Identification of gut microbiome alterations, discovery of microbial or metabolite-based biomarkers, association with disease onset or progression, and/or therapeutic effects on cognitive, neurological, or inflammatory outcomes were evaluated. Short-chain fatty acids(SCFAs) such as butyrate and acetate were found to be noninvasive biomarkers in patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), and Parkinson's disease (PD). Lower SCFA levels correlated with cognitive decline. Diagnostic accuracy improved when SCFA combinations were used, with AUCs ranging from 0.75 to 0.87. Trimethylamine N-oxide(TMAO) levels showed inconsistent associations, with both elevated and reduced levels linked to disease risk. Therapeutic approaches targeting gut microbiota, including probiotics, prebiotics, dietary changes, and fecal microbiota transplantation, demonstrated cognitive benefits and modulation of gut-brain signaling pathways. Overall, gut-derived biomarkers offer a promising avenue for early diagnosis and novel therapeutic approaches in AD and PD, while acknowledging that evidence in other neurodegenerative diseases remains limited through modulation of the gut-brain axis.",
"42237711": "ID: 42237711\nTitle: Gut Microbiome-Sleep Crosstalk: Mechanistic Pathways, Dysbiosis Signatures, and Microbiome-Based Interventions.\nAbstract: This review examines the bidirectional relationship between sleep regulation and the gut microbiome within the gut-brain axis, with particular attention to mechanistic pathways, disorder-associated dysbiosis patterns, and microbiome-targeted interventions in insomnia, obstructive sleep apnea, circadian disruption, and sleep loss-related states. We critically synthesized evidence from both human and preclinical studies, focusing on microbial metabolites, neuroimmune and neuroendocrine signaling, circadian regulation, and intervention-based approaches. Rather than only summarizing individual studies, we aimed to distinguish associative human findings from mechanistic evidence derived mainly from animal models. Current evidence supports a bidirectional link between sleep and the gut microbiome. Microbiota-derived metabolites, particularly short-chain fatty acids, tryptophan-related metabolites, and gamma-aminobutyric acid, appear to influence sleep homeostasis through effects on intestinal barrier integrity, inflammatory tone, stress-axis regulation, and central signaling pathways. Across sleep disorders, recurrent microbial patterns include reduced abundance of potentially beneficial taxa such as Bifidobacterium and Faecalibacterium and enrichment of pro-inflammatory or stress-associated taxa, although these signatures are not yet fully consistent across cohorts or disorders. In humans, most data remain observational and support association rather than causation, whereas stronger mechanistic support comes from experimental models of sleep deprivation, intermittent hypoxia, and microbiota transfer. Early intervention studies suggest that selected probiotics, prebiotics, dietary modulation, and related microbiome-directed strategies may improve sleep-related outcomes, but the magnitude and reproducibility of these effects remain uncertain. The gut microbiome represents a promising mechanistic and therapeutic target in sleep medicine, but clinical translation is still constrained by heterogeneity in microbiome profiling, sleep phenotyping, intervention design, and strain-specific effects. Future work should prioritize longitudinal human studies, standardized outcome measures, and mechanistically informed trials capable of identifying clinically actionable and biologically credible microbiome signatures.",

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.",

A comprehensive literature search across Web of Science, Scopus, and Google Scholar identified 29 original studies, based on in vitro, animal, and human research. Findings demonstrated that Aronia melanocarpa, rich in polyphenols like anthocyanins and proanthocyanidins, exerts cognitive-enhancing, anxiolytic-like, and antidepressant-like effects. These outcomes are mediated by mechanisms involving antioxidant activity, modulation of neurotransmitter systems, inhibition of monoamine oxidases, reduction of neuroinflammation, modulation of gut microbiota, and upregulation of brain-derived neurotrophic factor (BDNF). Animal models of Alzheimer's disease and stress-induced disorders, along with human clinical trials, corroborated these effects. The review underscores the therapeutic promise of Aronia melanocarpa nutraceuticals in neuropsychiatric health and highlights the need for further clinical validation.",

Neuroinflammation is a critical driver of disease progression and represents a promising target for intervention. Emerging evidence highlights lactate as a signaling metabolite that regulates inflammatory responses through protein lactylation. Given the involvement of 14-3-3 proteins in PD pathogenesis, we investigated whether lactate confers neuroprotection by promoting 14-3-3 lactylation and modulating neuroinflammatory signaling in PD. A rat model of PD was induced by subcutaneous injection of Rotenone (ROT) into the dorsal cervical region. Lactate was administered intracerebroventricularly. Motor function was assessed using open field, grid, and suspension tests. TH-positive neurons in the substantia nigra were evaluated by immunohistochemistry. The lactylation of 14-3-3 proteins and their interaction with NLRP3 were examined by co-immunoprecipitation (Co-IP). Mitochondrial localization of GSDMD was visualized by immunoelectron microscopy. The cytosolic mtDNA was assessed using qPCR. NLRP3 inflammasome components, the cGAS-STING pathway, and mitochondrial GSDMD were analyzed by western blotting. Levels of inflammatory cytokines and cGAMP were quantified by ELISA. Lactate ameliorated motor deficits and dopaminergic neuron loss in ROT-treated rats. Lactate increased 14-3-3 lactylation and enhanced 14-3-3 binding to NLRP3, accompanied by reduced NLRP3 inflammasome activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppressed cGAS-STING pathway activation. Lactate exerts neuroprotective effects in PD through a mechanism associated with enhanced 14-3-3 lactylation, reduced NLRP3/GSDMD pathway activation, attenuated GSDMD-associated mitochondrial injury, decreased cytosolic mtDNA levels, and suppression of cGAS-STING signaling.",

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.",

It is commonly used in the treatment of insomnia and forgetfulness. Previous studies have indicated that the oligosaccharide esters (OE) derived from Yuanzhi exhibit neuroprotective and memory-enhancing activities.\u00a0However, its underlying mechanisms, particularly those involving the gut-brain axis, remain unclear. This study aimed to investigate the therapeutic efficacy and underlying mechanisms of Oligosaccharide Esters (OE) from Polygala tenuifolia Willd. against memory dysfunction in mice, with a specific focus on the gut-brain axis. A mouse model of memory dysfunction was induced using D-galactose combined with AlCl\u2083. Behavioral tests, molecular biology techniques (histopathology, enzyme-linked immunosorbent assay (ELISA), immunohistochemistry, and Western blot), and multi-omics approaches (16S rRNA sequencing and lipidomic analysis) were employed to investigate the therapeutic efficacy of OE against memory dysfunction. Meanwhile, with the aid of fecal microbiota transplantation (FMT) assay, we observed the repair of brain and colonic tissues, inflammatory responses and intestinal permeability, further clarified the regulatory effect of OE on gut microbiota, and ultimately revealed the underlying mechanisms of OE mediated by the gut-brain axis. OE administration significantly enhanced learning and memory in MD mice, repaired neuronal damage in the hippocampal regions (CA1, CA3, DG) of the MD mouse brain, and increased the number of Nissl bodies. OE elevated the serum levels of BDNF and CREB and reduced the TMAO level; simultaneously, it enhanced the activities of SOD and GSH-Px and decreased the MDA content in the brain tissue. OE treatment modulated the relative abundance of the gut microbiota in MD mice, restored the microbial imbalance induced by memory deficits, and particularly affected the abundances of Firmicutes, Bacteroidetes, their ratio (F/B), and genera such as Ligilactobacillus. Lipidomics analysis indicated that OE exerts its therapeutic effects primarily by regulating the glycerophospholipid metabolism pathway, and a total of 17 key differential lipid metabolites were identified. Correlation analysis further revealed that the levels of key differential lipid metabolites, LysoPC(22:2) and PC(38:4), were significantly positively correlated with the levels of neuroprotective factors (CREB, BDNF) and the activities of antioxidant enzymes (SOD, GSH-Px), but were significantly negatively correlated with the harmful metabolite TMAO and the oxidative damage product MDA. In contrast, the lipid metabolite GPEA exhibited a trend opposite to that of LysoPC(22:2) and PC(38:4). Further investigation results demonstrated that OE could repair pathological damage in colon tissue, regulate the levels of the microbial metabolite TMAO and the neurotransmitter 5-HT, reduce the levels of pro-inflammatory factors (LPS, TNF-\u03b1, IL-6) in both the brain and colon, and inhibit the abnormal activation of astrocytes and the abnormal hyperphosphorylation of Tau protein. The results of correlation analysis indicated that beneficial bacteria [e.g., Ligilactobacillus) and beneficial lipids (e.g., LysoPC(22:2) and PC(38:4)] were collectively significantly negatively correlated with key pathological indicators (e.g., TMAO and TNF-\u03b1) and were positively correlated with the neurotransmitter (e.g., 5-HT). OE also significantly up-regulated the expression of tight junction proteins (Occludin, Claudin-5) in both brain and colon tissues, thereby structurally repairing the damaged gut-brain barrier. FMT experiments showed that FMT improved the learning and memory abilities of mice, repaired neuronal damage in the hippocampus (CA1, CA3, DG), and increased the number of Nissl bodies. In addition, FMT alleviated colonic tissue injury, attenuated inflammatory responses in the brain and colon, and reduced intestinal permeability in MD mice, exerting a therapeutic effect similar to that of OE. OE exerted anti-amnestic effects via the gut-brain axis, primarily by alleviating neuroinflammation and oxidative stress, restoring gut microbiota homeostasis, and regulating glycerophospholipid metabolism, ultimately improving learning and memory abilities in MD mice.",

Emerging evidence suggests that gut microbiota and their metabolites modulate neuroinflammation and neuronal survival, playing critical roles in neurological disorders. However, their contributions to CIH-related cognitive dysfunction remain incompletely understood. Here, we show that CIH caused gut dysbiosis, marked by reduced Bifidobacterium pseudolongum (B.p). FMT and 16S rRNA sequencing revealed protective associations of B.p in CIH-induced cognitive impairment. B.p supplementation mitigated the activation of microglia, reduced pro-inflammatory cytokine expression (TNF-\u03b1, IL-6, IL-1\u03b2), and attenuated hippocampal neuronal PANoptosis, thereby alleviating cognitive dysfunction. SCFAs targeting metabolomics demonstrated that B.p supplementation restored acetate levels in serum. Consistently, oral acetate supplementation replenished acetate levels and reproduced the neuroprotective and anti-neuroinflammatory effects of B.p. In vitro, acetate reduced mitochondrial DNA release, inhibited cGAS-STING (cyclic GMP-AMP synthase-stimulator of interferon genes) activation, and attenuated PANoptosis in HT22 cells. Collectively, our findings demonstrated that B.p supplementation was associated with restoration of acetate metabolism and attenuation of hippocampal neuroinflammation and neuronal PANoptosis, thereby alleviating CIH-induced cognitive dysfunction.

Epidemiological studies associate physical exercise with reduced AD risk (30-45%), yet mechanisms remain incompletely resolved. Preclinical studies demonstrate that exercise-induced myokines (Irisin, BDNF, Cathepsin B) modulate AD pathology by: (1) attenuating amyloid-beta (A\u03b2)/tau accumulation, (2) suppressing neuroinflammation, and (3) enhancing synaptic plasticity. However, human exercise interventions show conflicting results influenced by APOE genotype, age, and exercise modality. Associative human data suggest that Interleukin-6 (IL-6) exemplifies pleiotropy-affording neuroprotective effects in acute contexts but potentially detrimental effects in states of chronic inflammation. Therapeutic hurdles include blood-brain barrier (BBB) penetration, pleiotropic risks, and patient heterogeneity. Emerging concepts such as combinatorial approaches (nanocarriers, exercise mimetics) and biomarker-driven trials are proposed as hypothetical future strategies; however, these remain unvalidated and require substantial preclinical development before implemented in clinical care. This narrative review is structured around three thematic sections: mechanistic foundations of myokine neuroprotection, translational barriers to therapeutic development, and a strategic framework for future research. The muscle-brain axis represents a compelling but complex therapeutic target. Based on current preclinical and correlational human evidence, future research should prioritize mechanistic rigor, standardized biomarker validation, and clinically viable delivery strategies. Notably, several approaches discussed herein-including nanocarrier delivery systems, exercise mimetics, and combinatorial myokine cocktails-remain speculative and are presented as future research directions rather than established therapeutic interventions.",

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.

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.",

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 aimed to systematically investigate the neuroprotective effects of NTQ against TBI model mice and elucidate its underlying molecular mechanisms. A controlled cortical impact (CCI) mouse model of TBI was established, and animals received NTQ treatment for 28 consecutive days. NTQ's neuroprotective efficacy was comprehensively evaluated via behavioral tests (functional recovery), cerebral blood flow imaging (vascular integrity), and electromyography (neural activity). Post-treatment inflammatory levels in TBI mice were assessed by quantifying inflammatory cytokine expression using quantitative real-time PCR and detecting microglial activation via immunofluorescence. Mechanistic exploration integrated network pharmacology, transcriptomics and bioinformatics analyses to identify NTQ's active components, potential targets, and associated pathways in TBI. In vivo experiments demonstrated that NTQ significantly improved behavioral outcomes, restored cerebral blood flow, and enhanced neural activity in TBI mice. Concurrent with these functional benefits, NTQ robustly suppressed neuroinflammation, as evidenced by reduced pro-inflammatory cytokine expression and attenuated microglial activation. Integrated network pharmacology and transcriptomic analyses confirmed that NTQ acts primarily through immune regulation after TBI, modifying key immune-related molecules and pathways. Specifically, NTQ intervention elicited pronounced downregulation of immune-inflammatory mediators, including Cd3g, Cd5, Cd8a, Epcam, Slamf7, Il16, Il17r, Il18rap, Cxcl9, Cxcr6, Tnfsf11, and Tnfsf15. Further mechanistic dissection identified six putative bioactive constituents of NTQ, including nicotinamide, curcumin, baicalin, chrysin, daidzein, and apigenin, which may remodel the intracerebral immune microenvironment after TBI through three core pathways: amine ligand-binding receptors, nuclear receptor meta-pathways, and arachidonic acid metabolism. Taken together, our integrated analyses demonstrate that NTQ exerts neuroprotective effects in TBI by modulating immune responses and suppressing neuroinflammation, thereby establishing NTQ as a promising multi-target therapeutic agent for TBI.",

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.",

This study evaluated DHA-enriched egg yolk lipids in 5 \u00d7 FAD mice at doses of 1 and 2 g kg-1 day-1 for eight weeks, corresponding to human consumption of 1 or 2 eggs daily. The high-dose intervention (2 g kg-1) ameliorated cognitive deficits and neuronal damage by upregulating BDNF and NGF, improving synaptic plasticity (PSD95, SYN, Drebrin), increasing dendritic spine density, restoring cholinergic and glutamatergic neurons, and suppressing microglial activation-induced neuroinflammation (IL-6, IL-1\u03b2, IFN-\u03b3). Metabolomic and gut microbiota analysis revealed increased levels of neuroprotective metabolites (PC (20\u2009:\u20092/22\u2009:\u20096), neuroprotectin D1) and enhanced abundance of AD-beneficial genera including Muribaculaceae and Lachnospiraceae.

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.",

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.",

Currently, AH are increasingly being studied for their potential to boost neuroplasticity and neurogenesis, as they can stimulate the growth of new neurons, improve the complexity of existing ones, and support cognitive resilience. Recent evidence-based research suggests the potential to use these AH and their formulations to develop new therapies for addressing cognitive decline during aging and neurodegenerative disorders (NDD). Neurogenesis is known to be compromised in mild cognitive impairment (MCI) and is impaired early in animal models of Alzheimer's disease (AD), suggesting that rescuing neurogenesis may restore hippocampal plasticity and attenuate neuronal vulnerability and memory loss. Several AH, including Brahmi (Bacopa monnieri), Gotu Kola (Centella asiatica), Ashwagandha (Withania somnifera), Shankhapushpi (Convolvulus pluricaulis), Guduchi (Tinospora cordifolia), and Yashtimadhu (Glycyrrhiza glabra), are well recognized for their cognitive-enhancing and neuroprotective properties. Further, in chronic stress models, the neurogenic effects of AH are proposed to be mediated by mechanisms including antioxidant and anti-inflammatory effects, modulation of neurotransmitters, and effects on the gut microbiota. Neurotrophins (particularly brain-derived neurotrophic factor -BDNF) are important mediators of neuroplasticity as they modulate multiple processes, including synaptic plasticity, axonal and dendritic growth, spine morphogenesis, and neurogenesis. BDNF is compromised in depression and recovered by conventional antidepressants. The antidepressant-like effects of AH are associated with the reversal of chronic stress-induced impairment in neuroplasticity, most notably through up-regulation of BDNF, activation of downstream signaling pathways, and increased neurogenesis in the hippocampus and/or prefrontal cortex. This review summarizes current developments regarding AH's propensity to enhance neuronal plasticity and its therapeutic role as a modulator of neurogenesis. It also emphasizes the importance of using them as adjuvant therapy to attenuate cognitive deficits associated with aging and neurodegeneration.",
"42309244": "ID: 42309244\nTitle: PPAR\u03b1 activation with fenofibrate confers hippocampal neuroprotection but lacks disease-modifying efficacy in chronic temporal lobe epilepsy.\nAbstract: Activation of peroxisome proliferator-activated receptor alpha (PPAR\u03b1) suppresses neuroinflammation and may interrupt epileptogenesis. We tested whether early intervention with the PPAR\u03b1 agonist fenofibrate exerts disease-modifying effects in the chronic phase of the lithium-pilocarpine model of temporal lobe epilepsy. Male Wistar rats received fenofibrate (100\u202fmg/kg, i.p., daily for 15 days) initiated 1\u202fh after status epilepticus. Outcomes were assessed 1-3 months later. Fenofibrate significantly attenuated neuronal loss in the dorsal CA1 subfield and ventral hilus of the hippocampus, partially reduced astrogliosis in the hilus, and decreased the proportion of amoeboid microglia in CA1. Behaviorally, fenofibrate prevented the TLE-induced reduction in risk-assessment exploration in the elevated plus maze, without affecting general locomotion or anxiety. Critically, fenofibrate did not alter the incidence of spontaneous recurrent seizures, interictal spike frequency, or the pathological reduction in delta and theta EEG power. It also failed to normalize the aberrant cortical response to pentylenetetrazol or reduce seizure severity. These findings demonstrate that early PPAR\u03b1 activation confers region-restricted neuroprotection and modest behavioral benefit, but does not suppress the core pathophysiological features of chronic epilepsy. The results dissociate neuroprotection from antiepileptogenesis and caution against assuming that anti-inflammatory interventions alone are sufficient for disease modification in temporal lobe epilepsy.",
"42309440": "ID: 42309440\nTitle: Plant-based neuroprotection against memory impairment: Insights from Drosophila melanogaster models of neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterised by the progressive dysfunction of neurons, and memory impairment is one of their most debilitating clinical manifestations. The etiopathogenic mechanisms are multifactorial, such as protein misfolding, oxidative stress, and mitochondrial malfunction and synaptic degeneration along with neuroinflammation. As yet, therapists still focus mainly on symptomatic treatment and no agents are found to halt or reverse the decline of cognitive, indicating what is more needed is other kinds of neuroprotective strategy. In this context, the plant-derived phytochemicals stand out as promising candidates owing to their multi-targeted mode of action, favourable safety profile and long-standing use in traditional medicine systems. These bioactive compounds modulate oxidative stress, inflammatory signalling, neurotransmitter balance, apoptotic pathways and protein aggregation to elicit neuroprotection. The attention of the research community has also turned towards using Drosophila melanogaster as a model system for neurodegenerative-related studies due to its genetic tractability, accessible behavioural learning and memory tests, and the evolutionary conservation of potentially important biological pathways. This review consolidates recent evidence regarding plant-based neuroprotective strategies against memory impairment, with a specific focus on mechanistic mechanisms elucidated from Drosophila models of neurodegenerative diseases. Integrating findings across molecular, cellular and behavioural levels, the review illustrates the therapeutic promise of phytochemicals and reaffirms Drosophila as a valuable preclinical tool. It also addresses practical translational considerations, such as bioavailability, standardisation, and clinical validation, and sets forth future directions for effectiveness of plant-based interventions to facilitate improvements out in the real world.",

This review synthesizes 122 high-impact studies using ADNI data or biospecimens from 2023 to mid-2025 to clarify mechanisms of Alzheimer's disease (AD) progression. Studies describe impairment of glymphatic clearance and the impact of cerebral small vessel disease, trajectories of amyloid beta and tau deposition, inflammation, metabolic disturbances, synaptic dysfunction, and neurodegeneration, leading to cognitive impairment and neuropsychiatric symptoms. Multifactorial contributions from genetic and epigenetic influences, co-pathologies and comorbidities, and mechanisms of resilience modulate disease progression.

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.",

It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.",

Current reliance on clinical milestones (e.g., motor fluctuations, cognitive decline) is limited by non-linear progression and the absence of objective measures. Although biomarkers like aggregated \u03b1-synuclein, MRI, and PET are under investigation, their correlation with clinical progression remains modest. Robust, reproducible endpoints are urgently needed to evaluate disease-modifying therapies across diverse phenotypes, accounting for genetic background, age of onset, co-pathologies, and motor/autonomic/cognitive domains. Given this complexity, single-target interventions are likely insufficient. We propose a multi-domain therapeutic framework for aPD that integrates: (A) simultaneous targeting of key pathological cascades, including \u03b1-synuclein aggregation, mitochondrial dysfunction, oxidative stress, proteostasis imbalance, neuroinflammation, and the gut-brain axis; (B) biology-driven patient stratification using emerging biomarkers to match subgroups with targeted interventions; and (C) systematic management of comorbidities and lifestyle factors, such as cardiovascular health and exercise, to enhance neuroresilience. Finally, advancing aPD care requires addressing systemic determinants, including global healthcare inequities, and prioritizing caregiver well-being. Mechanistically informed, patient-centered strategies that combine multi-target therapies with precision stratification and holistic support will be essential to modify disease progression and improve long-term outcomes.",

Despite extensive research, effective disease-modifying therapies remain unavailable. Increasing evidence highlights the gut-brain axis as an important contributor to AD pathogenesis, particularly through amyloid-producing gut microbes that promote immune activation, neuroinflammation, and cerebral amyloid accumulation. This review summarizes current evidence linking gut microbiota (GM) dysbiosis to AD, focusing on microbial metabolites, neuroinflammatory pathways, and microbiota-targeted therapeutic strategies. A systematic analysis of experimental and clinical studies reveals that altered gut microbial composition is associated with systemic and neuroinflammation, blood-brain barrier dysfunction, oxidative stress, and neuronal damage. Key microbial metabolites, including short-chain fatty acids and indole derivatives, exhibit neuroprotective effects by regulating immune responses, maintaining barrier integrity, and supporting neuronal energy metabolism; disruption of these metabolites may accelerate neurodegeneration. Microbiota-based interventions such as probiotics, prebiotics, dietary modification, and fecal microbiota transplantation show beneficial effects in preclinical models by restoring microbial balance and reducing neuropathological features, although clinical evidence in humans remains limited. Overall, current findings support a contributory role of gut dysbiosis in AD and suggest that targeting the GM may offer a promising complementary strategy for disease modification and future therapeutic development.",

This study investigated the role of HIF-1\u03b1 in regulating SG formation and NLRP3 inflammasome activation following I/R injury in NBO-induced neuroprotection. A total of 137 adult male SD rats underwent 2\u00a0h of MCAO, followed by 2, 6, 24 or 48\u00a0h of reperfusion. NBO (95% O\u2082 at 2\u00a0l/min) was administered for 2\u00a0h at the onset of reperfusion. HIF-1\u03b1 inhibitor (YC-1) was administered 2\u00a0h before MCAO. Brain damage was assessed by infarct volumes (TTC staining), LDH and ROS levels (ELISA), and apoptotic and pyroptosis cell death (flow cytometry and TUNEL assay). Gene and protein levels of HIF-1\u03b1 and inflammasome related factors (IL-18, IL-1\u03b2, NLRP3, cleaved-Caspase-1, GSDMD-N, ASC, TXNIP) were analyzed. SG proteins levels (G3BP1, TIA-1) and DDX3X were detected by Western blot. Co-IP detected the interaction between DDX3X and G3BP1 or NLRP3. Infarct volume, LDH expression, ROS levels, and cell death (apoptosis and pyroptosis) were significantly increased after I/R injury. NBO and YC-1 treatments significantly reduced infarct volume, LDH and ROS levels, and cell death at 24 and 48\u00a0h of reperfusion. NBO suppressed the expression of inflammasome-related markers (IL-1\u03b2, IL-18, NLRP3, TXNIP, ASC, cleaved-Caspase-1, GSDMD-N) at both mRNA and protein levels. Co-IP analysis showed that I/R enhanced the interaction between DDX3X and NLRP3, which was suppressed by NBO and YC-1. NBO increased SG formation by regulating G3BP1 and TIA-1 expression and strengthened the interaction between DDX3X and G3BP1. NBO\u00a0+\u00a0YC-1 did not show additive effects, indicating that the two treatments act through the same HIF-1\u03b1-dependent pathway. NBO exerts strong neuroprotection against ischemic stroke by inhibiting HIF-1\u03b1-mediated NLRP3 inflammasome activation and enhancing SG formation via DDX3X-G3BP1 interaction. This study identifies HIF-1\u03b1 as a key mediator of post-ischemic inflammation and stress response, highlighting NBO as a potent, mechanism-based therapeutic in ischemic stroke.",
"42320726": "ID: 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.",

Increasing evidence implicates gut microbiota dysbiosis in epilepsy pathophysiology, with short-chain fatty acids (SCFAs) emerging as key microbial metabolites with neuroprotective and anti-inflammatory properties. Clinical studies show that people with DRE exhibit gut microbiota alterations that may impair fecal SCFAs production. Here, we investigated whether supplementation of SCFAs confers disease-modifying effects in a preclinical model of DRE. Adult male mice were subjected to status epilepticus (SE) and subsequently treated with a balanced mixture of acetate, propionate, and butyrate, or vehicle. Seizure frequency and temporal progression were monitored for 70 days by electroencephalography (EEG). At the study end point, cognitive performance, brain and gut histopathology, and neuroinflammation were assessed, together with metabolomic profiling of feces and blood. Brain SCFA levels and receptor expression were also analyzed in mice and in brain tissue from individuals with DRE. SCFA supplementation reduced the proportion of mice exhibiting a progressive phenotype and decreased the overall progression index (PI) 3-fold, without significantly altering overall daily seizure frequency. Treatment reduced seizure clustering, improved cognitive deficits, restored hippocampal and intestinal alterations, and partially normalized cerebral SCFAs levels. Metabolomic profiling in epileptic mice and analysis of human epilepsy brain tissue support a mechanistic contribution of gut-brain axis dysfunction to disease progression. These findings identify SCFAs supplementation as a therapeutic strategy capable of modifying disease trajectory in experimental DRE, with clear translational relevance. ANN NEUROL 2026.",

Lycium ruthenicum Murray anthocyanins (LRA), a major bioactive component of black goji berry, have antioxidant and anti-inflammatory activities, but their gut microbiota-mediated neuroprotective mechanism in PD remains unclear. Here, we established a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model and treated mice with different doses of LRA. Behavioral tests, inflammatory and oxidative stress assays, Western blotting, 16S ribosomal RNA gene sequencing, and targeted metabolomic analysis were integrated to evaluate the effects of LRA. LRA improved motor dysfunction, exploratory behavior, and cognitive impairment in MPTP-induced PD mice, accompanied by reduced inflammatory cytokines and oxidative stress and partial restoration of striatal neurotrophic and dopaminergic markers. Moreover, LRA reshaped the gut microbiota, particularly by restoring Lachnospiraceae_NK4A136_group, unclassified_f__Lachnospiraceae, and Parabacteroides, and shifted tryptophan metabolism toward serotonin and indole derivatives, including indole-3-lactic acid, indole-3-acetic acid, and indole-3-propionic acid, while reducing quinolinic acid and xanthurenic acid.

LRRC8A (SWELL1) is the essential VRAC subunit. We observed seizure-induced, subunit-specific changes in microglial VRAC expression and investigated its function using conditional KO (cKO) of LRRC8A in microglia. SWELL1 cKO mice exhibited a male-specific increase in kainate-induced seizure severity, yet showed paradoxical neuroprotection against seizure-associated neuronal loss. Mechanistically, SWELL1 deletion led to a cell-autonomous reduction in microglial density and decreased release of VRAC-permeable neuroactive metabolites, including taurine, GABA, and glutamate in culture. Additionally, impaired phagocytic kinetics and reduced lysosomal biogenesis contributed to the observed neuroprotection. These findings reveal potentially novel roles for microglial VRAC in regulating seizure outcomes and microglia-neuron interactions.",

To investigate a diet-microbiome-metabolome axis associated with cognition, we integrated fecal metagenomics, diet, and multi-platform plasma metabolomics in 505 older adults from four ADRCs. Several microbes broadly associated with circulating metabolites were also linked to multiple measures of cognitive performance. These taxa exhibited coordinated metabolic signatures, with cognition-positive microbes associated with antioxidant, lipid, and microbial-host co-metabolites, and microbes negatively associated with cognition were linked to inflammatory and aromatic amino acid-derived metabolites. Dietary patterns, particularly the Healthy Eating Index Greens and Beans component, were associated with microbial composition and metabolomic structure. Mediation analyses supported a diet-microbe-metabolite-cognition pathway, while metabolites remained associated with cognition after accounting for microbial features. These findings highlight the metabolome as a central integrator of diet, microbial activity, and cognitive function.",

Here, we established a clinically relevant gene-environment interaction mouse model of PD by subjecting LRRK2 G2019S KI mice to recurrent Citrobacter (C.) rodentium infection, a murine model of enteric bacterial inflammation. Repeated infection induced progressive PD-like phenotypes selectively in KI mice, including motor impairment, reduced locomotor activity, impaired motor coordination, selective nigrostriatal dopaminergic neurodegeneration, enhanced neuroinflammation, and pathological phosphorylated \u03b1-synuclein (p-\u03b1Syn) accumulation, whereas wild-type (WT) mice remained largely resistant. Mechanistically, infected KI mice developed markedly exacerbated colonic inflammation, epithelial barrier dysfunction, increased intestinal permeability, and enhanced inflammasome activation despite normal bacterial clearance, indicating that pathogenic LRRK2 signaling amplifies inflammatory responses rather than impairing antimicrobial defense. In parallel, recurrent infection induced pronounced intestinal p-\u03b1Syn accumulation and expansion of pathology beyond the epithelial layer in KI mice, supporting a gut-brain axis mechanism linking intestinal inflammation to neurodegeneration. Collectively, these findings demonstrate that the LRRK2 G2019S mutation functions as a sensitizing factor that cooperates with recurrent enteric inflammation to drive PD-related pathology. This study establishes a physiologically relevant LRRK2 G2019S gene-environment interaction mouse model that recapitulates key behavioral, neuropathological, and inflammatory features of PD.",

Defects in oxidative phosphorylation, excess Reactive Oxygen Species (ROS), and impaired mitophagy cause an imbalance in neuronal energy and promote the release of mitochondrial Damage-Associated Molecular Patterns (DAMPs) that activate microglial inflammasomes and enhance inflammatory signalling. Current therapeutic strategies have largely targeted individual pathways and have been unable to effectively modulate this interrelated mitochondrial immune axis or achieve efficient delivery to the Central Nervous System (CNS). This review addresses the dual promise of berberine therapy, a biologically active plant alkaloid that enhances mitochondrial production via AMPK/PGC-1\u03b1 and SIRT1, restores membrane potential, promotes mitophagy, and inhibits NF-\u03baB and NLRP3-mediated inflammation. Nevertheless, this compound's weak solubility, limited bioavailability, and extremely poor Blood-Brain Barrier (BBB) penetration limit its therapeutic application. Encapsulation of berberine in polymeric nanoparticles, including Polyethylene glycol (PEG)-based polymeric nanoparticle systems, offers improved stability, bioavailability, and targeted mitochondrial delivery. An effective method for reducing neuroinflammation and mitochondrial dysfunction is this comprehensive phytochemical nanotechnology technique.",

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.",

Wettst. in Parkinson's disease: In Silico and preclinical insights into dopaminergic neuroprotection.\nAbstract: Parkinson's disease (PD) presents a formidable therapeutic challenge rooted not in a singular pathogenic event but in the convergent failure of mitochondrial homeostasis, redox balance, \u03b1-synuclein proteostasis, autophagy-lysosomal integrity, and neuroinflammatory amplification within substantia nigra dopaminergic neurons. Existing dopaminergic pharmacotherapies address symptomatic deficits while leaving the underlying neurodegenerative cascade unchecked, underscoring the need for disease-modifying strategies with multi-target mechanistic reach. This review examines bacoside-A, the principal triterpenoid saponin complex of Bacopa monnieri (L.) Wettst., as a structurally distinctive, polypharmacological neuroprotective scaffold whose biological relevance emerges from convergence with core vulnerability pathways driving dopaminergic degeneration. Integrating in silico, in vitro, and in vivo evidence, we examine how bacoside-A engages molecular targets including \u03b1-synuclein aggregation intermediates, monoamine oxidase-B, LRRK2 kinase, PINK1-Parkin mitophagy regulators, and the redox sensor DJ-1, with computational predictions providing a coherent mechanistic framework for findings observed across MPP\u207a-, rotenone-, and 6-OHDA-based preclinical models, including attenuation of mitochondrial dysfunction, oxidative amplification, and apoptotic signalling, and partial nigrostriatal preservation with motor improvement in vivo. This review reframes bacoside-A as a stress-buffering, network-active modulator most relevant during early, pre-degenerative disease stages. While no clinical trial has yet evaluated bacoside-A in PD, and findings from cognitive or other non-PD indications cannot be extrapolated as efficacy evidence, the convergent mechanistic, computational, and preclinical evidence presented here provides a strong rationale for advancing bacoside-A toward systems pharmacology-guided preclinical and clinical evaluation as an adjunct neuroprotective candidate.",
"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.",

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.",

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.",

To explore correlations between serum erythropoietin (Epo) concentrations, perinatal risk factors, red blood cell transfusions and recombinant human erythropoietin (rHuEpo) with outcomes including retinopathy of prematurity (ROP) and brain injury on magnetic resonance imaging (MRI) in extremely preterm infants. This is a post hoc analysis of data from the Preterm Erythropoietin Neuroprotection Trial of preterm infants born between 24 0/7 and 27 6/7 weeks gestation and randomized to placebo or rHuEpo treatment (N\u2009=\u2009941). Serum Epo concentrations were collected within 24 hours (baseline) and at 7, 9, and 14 days. MRI was obtained at 36 weeks postmenstrual age (N\u2009=\u2009220). Baseline Epo concentrations negatively correlated with gestational age, delayed cord clamping, and Apgar scores, and positively correlated with intraventricular hemorrhage and risk of death. Neither endogenous Epo at baseline nor trajectories from birth to 14 days were associated with ROP. In the placebo group, Epo at 1 week of life (r\u2009=\u20090.26, p\u2009=\u20090.033) and 2-week area under the curve (r\u2009=\u20090.28, p\u2009=\u20090.019) positively correlated with white matter injury. In the treatment group, Epo at 14 days negatively correlated with white matter injury (r\u2009=\u2009-0.35, p\u2009=\u20090.004). Grey matter injury negatively correlated with baseline Epo in the placebo group (r\u2009=\u2009-0.27, p\u2009=\u20090.01) but positively correlated in the treatment group (r\u2009=\u20090.23, p\u2009=\u20090.047). Transfusions were associated with severe ROP (p\u2009<\u20090.0001) and total brain injury on MRI (p\u2009=\u20090.007). Transfusion volumes in the first week of life were associated with a greater risk of severe ROP in males (p\u2009=\u20090.0006). Endogenous Epo concentrations in preterm infants are influenced by perinatal variables and correlate with poor outcomes. The association of Epo with MRI results differed between placebo and rHuEpo treatment groups. Transfusions were associated with increased ROP and brain injury on MRI.",

Existing pharmacological treatment including cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists are not very effective in reducing the symptoms and fail to prevent the disease process. The non-pharmacological treatment interventions such as diet, exercise and cognitive training have supportive effects and cannot be used as standalone treatments. Therapeutic gap has resulted in increased interest in complementary and alternative therapies, especially that of pleiotropic action of herbal medicines. Bacopa monnieri (BM) is an Ayurvedic herb that has historically been used to treat memory enhancement and now has both preclinical and clinical evidence supporting its ability to modulate neurotransmission, reduce oxidative stress and suppress neuroinflammation. However, such difficulties as low bioavailability, instability of the environmental factors, and variations in formulations restrict its clinical applicability. New technologies with a lot of potential such as microencapsulation technology can provide the solution to this problem by increasing stability, solubility, and targeted delivery of compounds that will increase treatment efficacy. This narrative review is a synthesis of the existing information on the pathogenesis of dementia, therapeutic approaches, and the effectiveness of BM as a complementary intervention. It points out links between traditional medicine and modern neuroscience, strengths and limitations of on-going evidence, gaps that need further research, such as long-term clinical trials, standardized formulations, and discovery of the role of BM in the gut-brain axis. BM is a prime example of how herbal medicines can be used as a complement to conventional treatment and play a role in multi-modal approaches aimed at reducing the cognitive impairment associated with dementia.",

Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.",

This study investigated whether fermentation enhances the antidepressant-like effects of Dendrobium officinale by comparing fermented Dendrobium officinale (FDO) with unfermented Dendrobium officinale (DO) in a chronic SD mouse model. FDO significantly ameliorated anxiety and depressive-like behaviors in SD mice. It reshaped gut microbial structures, enriched beneficial bacteria taxa such as Dubosiella, [Eubacterium]_coprostanoligenes_group, and Allobaculum, and increased SCFA levels. FDO also enhanced colonic ZO-1 and Occludin expression and reduced serum levels of LPS and the pro-inflammatory cytokines. At the central nervous system level, FDO inhibited the activation of hippocampal microglia and astrocytes; alleviated neuroinflammation; restored hippocampal TPH2, 5-hydroxytryptamine (5-HT), and 5-HIAA levels; and modulated the 5-HT1A/5-HT2A receptor balance. In addition, FDO upregulated BDNF, PSD-95, and SYN expression and reduced corticosterone (CORT) levels. Compared with DO, FDO showed more pronounced regulatory effects. Correlation analysis suggested that 5-HT may link gut microbial metabolites, inflammation, and synaptic plasticity. In summary, these findings support FDO as a potential GBA-targeted functional food for SD-related depressive-like behaviors.",

These microbial derivatives are emerging as promising approaches for tackling complex diseases, encompassing cancer, autoimmune diseases, and metabolic disorders, through modulation of host cell signalling pathways, including G protein-coupled receptors (GPCRs), the NF-\u03baB (Nuclear Factor Kappa B) pathway, and epigenetic regulatory pathways. Besides systemic effects, postbiotics may also have localized effects, such as epithelial regeneration, modulation of fibroblast functions, and control of collagen remodelling. Eventually, the scale-up in the production of postbiotics has initiated new avenues in improving sustainable agriculture and environmental biotechnology. This comprehensive review attempts to integrate mechanistic insights and translational applications, highlighting the therapeutic potential of postbiotics across biomedical and ecological domains. These observations could pave the way to bridge the gap between microbiome regulation, precision medicine, and sustainable biotechnology, thereby positioning postbiotics as a versatile tool addressing some of the most pressing health and sustainability challenges of the 21st century.",

Increasing evidence suggests that the gut microbiota acts as a central regulator of neuromuscular and neurocognitive aging through the integrated gut-brain-muscle axis. This review highlights how microbial dysbiosis, reduced short-chain fatty acid (SCFA) production, systemic endotoxemia, and altered microbial metabolites contribute to mitochondrial dysfunction, neuroinflammation, anabolic resistance, and impaired neuroplasticity. Key signaling mediators, including SCFAs, bile acids, tryptophan-derived metabolites, cytokines, and myokines such as irisin, brain-derived neurotrophic factor (BDNF), and cathepsin B, orchestrate bidirectional communication among the gut, skeletal muscle, and brain. We further discuss the role of exercise-induced microbiota remodeling and muscle endocrine signaling in promoting mitochondrial biogenesis and cognitive resilience. In addition, emerging translational strategies including probiotics, prebiotics, postbiotics, polyphenol-rich functional foods, marine bioactives, and precision nutrition are explored as potential interventions targeting this axis. Collectively, the gut-brain-muscle axis provides a novel systems biology framework for understanding cognitive frailty and developing integrated therapeutic strategies for healthy longevity.",

This relationship has not yet been investigated in monozygotic twin pairs, which represent an ideal model for minimizing genetic confounding. Materials and Methods: Seven twin pairs discordant for ACE and 15 for MoCA were enrolled. Stool samples were subjected to 16S ribosomal RNA-based microbiome analysis. Results: No significant differences in alpha or beta diversity were observed between MCI-discordant twin pairs at the genus or family level. The most robust finding was a significantly lower abundance of Lachnospiraceae in MCI-affected twins, identified independently by ANCOM-BC and LEfSe. Additional exploratory findings included higher abundances of Sutterella, Succinivibrio, Odoribacter, and Ruminococcus. However, several taxa showed opposing patterns between ACE- and MoCA-derived cohorts, highlighting the methodological impact of cognitive instrument selection. Conclusions: The convergent reduction of Lachnospiraceae across two independent analytical methods represents the most substantive finding. The remaining results are exploratory, limited by small sample size, restricted statistical power, and lack of availability to fully control for dietary habits, physical activity, and medication use. Validation in larger longitudinal twin cohorts with a standardized cognitive assessment is warranted.",

Recently, a novel model has been introduced, proposing two distinct ASyn propagation pathways: a bottom-up trajectory termed Body-first PD, and a central nervous system (CNS)-initiated pathway termed Brain-first PD. This distinction introduces new perspectives in the PD literature landscape regarding diagnosis, prognostic factors and patient management. This study set out to systematically synthesize the current literature comparing Brain-first and Body-first PD, with a focus on clinical characteristics and disease progression, diagnostic biomarkers, and management approaches. (2) Materials and Methods: A systematic literature search was conducted in March 2025 using PubMed, Cochrane Library, DOAJ and Google Scholar. Human observational, diagnostic, and interventional studies published between 2019 and March 2025, including patients with de novo or early PD, were eligible. Pre-motor REM sleep behavioral disorder (RBD) was used as the primary differentiation criterion. Risk of bias was evaluated using the Joanna Briggs Institute (JBI) critical appraisal checklists. Results were synthesized using a narrative approach. (3) Results: Sixteen studies comprising 2107 PD patients met the inclusion criteria. Body-first PD was associated with a higher non-motor symptom (NMS) burden, faster disease progression, and a higher prevalence of cognitive impairment. Additionally, Body-first PD patients exhibited more widespread and symmetrical neurodegeneration, along with electrophysiological and metabolic differences. Distinct biomarker and microbiome profiles were also observed between subtypes. No eligible studies addressing management approaches were identified. (4) Conclusions: In conclusion, the available evidence suggests that Brain-first and Body-first PD may represent two distinct pathophysiological entities, a proposal with great significance for the diagnosis, prognosis and management of PD patients. However, the predominantly cross-sectional nature of the current literature limits causal inference. Future longitudinal and interventional studies are required to clarify the potential clinical implications of this subtype classification theory.",
"42356195": "ID: 42356195\nTitle: Myelin Repair as a Neuroprotective Strategy for Multiple Sclerosis: From Bench to Bedside.\nAbstract: Multiple sclerosis (MS) is a neuro-inflammatory disease characterized by demyelination in the central nervous system (CNS). Although a substantial endogenous capacity for remyelination has been demonstrated, this process is frequently incomplete and exhibits marked intra- and inter-individual heterogeneity. Several factors influence the extent of spontaneous myelin regeneration, including age, sex, disease course, and lesion localization. Oligodendrocytes (OL), derived from oligodendrocyte progenitor cells (OPCs), are the principal myelinating cells of the CNS. The regenerative cascade involves several key stages, including OPC activation, recruitment, differentiation into oligodendrocytes (OL), and myelin deposition. This process is orchestrated in a spatiotemporal manner by a complex interplay of intracellular signaling pathways, genetic determinants, and dynamic microenvironmental cues, which together balance inhibitory and pro-remyelinating influences. Several lines of evidence indicate that chronically demyelinated axons are vulnerable to degeneration, whereas successful remyelination may confer neuroprotection. These observations underscore remyelination as a promising neuroprotective therapeutic target for preventing or slowing disability progression in MS, a condition in which gradual neuroaxonal degeneration is believed to underlie irreversible disability progression. In this review, we aim to bridge the gap between fundamental biological mechanisms of remyelination and their clinical relevance. We examine recent advances in in vivo techniques for assessing remyelination and discuss how these measures correlate with clinical and disability outcomes. In addition, we review recent clinical trials of remyelination-promoting therapies and analyze the challenges that have limited their advancement beyond phase II. Overall, we seek to provide a comprehensive overview of the remyelination process from bench to bedside, highlighting both the obstacles and the therapeutic potential of remyelination strategies in MS.",

Furthermore, AD patients and APP/PS1 mice, a transgenic model of AD, exhibit dysbiosis. Objectives: Using APP/PS1 mice treated from 2 to 8 months of age, we studied ileal and colonic epithelial integrity, intestinal barrier (IB) integrity assessed through tight junction (TJ) protein expression, local immune system, the presence/increase in A\u03b2 expression in enterocytes, and the protective effects of synbiotic treatment. Methods: The tissue was stained with Periodic Acid-Schiff and Alcian Blue to evaluate epithelial morphology and mucus production, and immunohistochemistry was performed to assess TJs, immune markers, and A\u03b2 expression. Results: Our results demonstrate that colonic and ileal epithelium of 8-month-old APP/PS1 mice displays IB impairment in term of alterations of goblet cells staining and TJ protein expression and signs of immune involvement. The ileum was more severely affected, showing a reduced epithelial surface area, decreased lysozyme production, and fewer tuft cells. Long-term synbiotic treatment largely prevented APP/PS1 mouse changes and caused a significant increase in A\u03b2 expression in all treated mice. Conclusions: These findings support the belief in early intestinal involvement in AD and highlight the potential of the microbiota as a target for early intervention aimed at modifying the progression to neurodegeneration. Increased epithelial A\u03b2 labeling after treatment raises the possibility of intestinal management of A\u03b2, which requires further validation.",

Here, we identify the bacterial metabolite imidazole propionate (ImP) as a modifier of ADRD pathology. In a cohort of 1196 cognitively unimpaired adults, higher plasma ImP levels were associated with lower preclinical cognitive scores and biomarkers of ADRD, both cross-sectionally and longitudinally. Fecal metagenomic analysis linked putative ImP producers to ADRD phenotypes. Genome-wide integrative analysis revealed a locus on chromosome 12 associated with both plasma ImP levels and AD risk in humans, supporting a host genetic contribution to ImP regulation and a causal role of this metabolite in AD. In mice, chronic ImP administration exacerbated AD-like pathology. ImP impaired brain endothelial barrier and promoted tau hyperphosphorylation in primary neurons, an effect blocked by glycogen synthase kinase-3\u03b2 inhibition. Together, this study links ImP to hallmarks of neurodegeneration and suggests that targeting ImP may represent a potential strategy to modify ADRD risk.",

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.",

We previously identified oral enrichment of Streptococcus parasanguinis (SP) and other species in individuals with cocaine use disorder (CUD), and here demonstrate that cocaine selectively enhanced SP growth in vitro . To investigate causality, antibiotic-pretreated wild-type C57BL/6 mice received chronic oral inoculation of SP, S. salivarius , Neisseria flavescens , or vehicle. SP-treated mice exhibited spatial memory impairment, increased brain IL-1\u03b2, and non-region-specific microglial activation, without detectable bacterial translocation into the brain. While amyloid-associated signaling changes were observed across all bacterial treatment groups, only SP induced cognitive deficits and neuroinflammation. Untargeted metabolomics identified distinct SP-associated oral-to-brain metabolite signatures, including cysteine S-sulfate (CSS) and altered histamine-associated metabolites. CSS and histamine induced neuroinflammatory and amyloid-associated responses in vitro . Together, these findings identify a cocaine-associated oral pathobiont that promotes neuroinflammation and neurodegeneration, suggesting a novel oral microbiome-brain axis in CUD.",

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.",
"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.",

Microvascular dysfunction emerges decades before clinical symptoms, driving irreversible neurodegeneration once established. Clinical results show that nonpharmacologic interventions demonstrate greater effectiveness: three-fold greater cognitive improvement and five-fold enhanced functional outcomes versus pharmacotherapy, while avoiding adverse effects that affect 40% of patients receiving pharmacological treatments. These interventions orchestrate convergent mechanisms: vascular restoration (reversing vasoconstriction, augmenting perfusion), metabolic reprogramming (mitochondrial/glucose optimisation), neuroinflammation resolution, oxidative stress mitigation, and synaptic preservation. Exercise, neuromodulation, dietary modification, environmental enrichment and conditioning medicine activate multilevel endogenous repair mechanisms inaccessible to pharmacological targeting. This review presents a comprehensive mechanistic framework elucidating how nonpharmacologic strategies modulate interconnected vascular/non-vascular domains. It highlights emerging bioelectronic medicine as a promising disease-modifying therapy, establishing nonpharmacologic interventions as first-line strategies that reconceptualize VCID from intractable neurodegeneration to a preventable, potentially reversible, condition.",

Although KP dysregulation has been linked to multiple diseases, a unifying framework explaining how localized metabolic perturbations propagate across organs -a \"Domino Effect\"- is lacking. This review provides a comprehensive synthesis of KP's dual, context-dependent roles in immunity, neurodegeneration, cardiovascular disease, and gastrointestinal disorders. We critically evaluate the mechanistic basis of KYN as a master regulator via the aryl hydrocarbon receptor (AhR) and NAD+ biosynthesis, resolving controversies surrounding its pro-versus anti-inflammatory and pro-versus antitumorigenic functions. Key findings reveal that KP metabolites determine disease outcomes: KYNA/QA balance in the brain, inflammatory vascular remodeling in the heart, and host-microbiome crosstalk in the gut. We further assess therapeutic targeting of KP enzymes (IDO1, TDO2, KMO) and AhR, acknowledging both promising preclinical data and clinical translation challenges. Finally, we propose that future strategies must move beyond conventional enzyme inhibition to include upstream regulatory mechanisms. This review proposes a \"Domino Effect\" framework to provide new avenues for biomarker discovery, precision medicine, and structure-based drug design targeting the KP.",

Upregulation of sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, reduces RGC loss and vision deficits in TON models, but mechanisms underlying these effects are not well understood. This study examined if Nrf2, a transcription factor that regulates antioxidant enzymes, helps mediate neuroprotective effects of SIRT1 in TON. Wild-type (WT) and Nrf2-deficient mice received an intravitreal injection with adeno-associated virus type 2 (AAV2) expressing an RGC-selective promoter-driven human SIRT1, green fluorescent protein (GFP), or Nrf2. TON was induced by repetitive mild head impacts, and vision was assessed by optokinetic responses (OKRs). RGCs from isolated retinas were immunolabeled with Brn3a antibodies and counted to quantify Brn3a+ RGC numbers. TON resulted in decreased Brn3a labeling and decreased OKR scores in AAV2/synuclein gamma (SNCG)/GFP-injected WT mice as compared with unimpacted mice; AAV2/SNCG/SIRT1 treatment attenuated this loss. This protective effect was absent in Nrf2-deficient mice subjected to TON, as these mice had significant decreases in Brn3a-labeled cells and OKR scores whether they received AAV2/SNCG/GFP or AAV2/SNCG/SIRT1 therapy. AAV2/SNCG/Nrf2-injected WT mice exhibited similar decreases in Brn3a labeling and OKR scores as AAV2/SNCG/GFP-injected WT mice. Nrf2 is implicated as an important downstream effector of SIRT1-mediated therapeutic effects given that Nrf2-deficient mice are unable to recapitulate the neuroprotective effects of AAV-based SIRT1 gene therapy. However, Nrf2 is not sufficient to induce similar neuroprotective effects when overexpressed selectively in RGCs. Results of this study define an important mechanism of SIRT1 gene therapy mediating RGC neuroprotection.",

Although studies on animals have suggested neurotoxic effects, evidence from humans is still scarce. This systematic review gathers existing human data to assess the presence, types, detection techniques, and neurological consequences of MNPs in different biological matrices. A comprehensive review was performed on peer-reviewed research concentrating on human studies that report the detection of MNPs in biological tissues and fluids. Four qualifying studies were identified: one clinical observational study, two cadaveric analyses, and one quasi-experimental trial. The data collected encompassed demographics, detection methods, types and concentrations of polymers, biological matrices examined, and neurological biomarkers. MNPs were observed in cerebrospinal fluid (CSF), faeces, urine, olfactory bulbs (OBs), and in brain, liver, and kidney tissues from postmortem cases. The polymers that were reported most frequently were polyethylene (PE) and polypropylene (PP). The detection methods included micro-Fourier transform infrared spectroscopy (\u00b5FTIR), pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), laser direct infrared imaging (LDIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Although the available evidence is limited, emerging findings indicate the possible accumulation of MNPs in the human central nervous system (CNS), particularly in individuals with dementia or compromised blood-brain barrier (BBB) integrity. Relationships were noted between MNP exposure and disruptions in the BBB, inflammatory markers, and alterations in the gut-brain axis. This review consolidates the findings and emphasizes the need for further exploration of human exposure to MNPs and their possible accumulation in neural tissues. Although there is variability in methodologies used in the reviewed articles, PE and PP stand out as the primary polymers of concern. While a direct causal relationship cannot yet be confirmed, the results highlight the necessity for improved detection methods, larger sample sizes, and long-term studies to better understand the impact of MNPs on neuroinflammation and neurodegeneration.",
"42398656": "ID: 42398656\nTitle: Ethyl acetate extract of Poecilobdella manillensis Lesson ameliorates ischemia stroke through inhibiting cell apoptosis and suppressing TLR4/NF-\u03baB-mediates neuroinflammation.\nAbstract: Poecilobdella manillensis Lesson is a well-recognized medicinal leech in traditional Chinese medicine and Guangxi Zhuang ethnic medicine. It has long been used to activate blood circulation and remove blood stasis for the treatment of ischemic stroke. Modern pharmacological research has verified its potent anticoagulant and anti-inflammatory activities. Current studies mainly focus on its polypeptide components that exert antithrombotic effects to improve cerebral ischemia, while the neuroprotective potential and related mechanisms of its small-molecule constituents remain largely unclear. This study aimed to investigate the therapeutic effects of the ethyl acetate extract (EA) of P. manillensis on cerebral ischemia-reperfusion injury and to clarify its underlying molecular mechanism. The chemical constituents of EA were identified by UPLC-Q-TOF-MS/MS. Network pharmacology and molecular docking were used to predict and verify core targets and pathways. Neuroprotective and anti-inflammatory effects of EA were evaluated in a rat MCAO/R model, OGD/R-injured SH-SY5Y cells, and LPS-stimulated BV2 cells, using histological staining, Western blot, immunohistochemistry, and RT-qPCR. Seven small-molecule components were identified in EA, and 314 overlapping targets related to ischemic stroke were screened. Network analysis showed that TLR4 was the core target, and the main enriched pathways included NF-\u03baB, Toll-like receptor, apoptosis and TNF signaling pathways. Consistent with the predicted results, EA significantly reduced cerebral infarct volume and improved neurological deficits in MCAO/R rats, and inhibited neuronal apoptosis and microglial inflammation in vivo. In vitro, EA notably improved the survival of OGD/R-injured neurons and suppressed LPS-induced inflammatory responses in BV2 cells. Meanwhile, EA markedly downregulated the expression of TLR4/NF-\u03baB and NLRP3 inflammasome-related molecules. The present study demonstrated that EA protects against cerebral ischemia-reperfusion injury by inhibiting neuronal apoptosis and TLR4/NF-\u03baB-mediated neuroinflammation. These findings provide a scientific basis for the traditional clinical application of P. manillensis and suggest that EA could serve as a potential therapeutic candidate for ischemic stroke.",

Local inflammatory responses in the retina and optic nerve are implicated in the pathology of glaucoma. In addition, microbial populations in other parts of the body have been linked to glaucoma. To explore the relationship between oral health and glaucoma we queried the FinnGen database (Risteys 10.0) to assess whether poor oral health carries an increased risk of subsequently developing primary open angle glaucoma (POAG). In a separate study, we also collected mouthwash samples and administered a questionnaire relating to oral health status to a cohort of participants enrolled in Diagnostic Innovations in Glaucoma Study (DIGS) that included 107 participants with glaucoma and 19 healthy non-glaucomatous controls. 16S sequencing was performed to characterize the number of bacteria species and total bacteria count of the samples. A significant association between having dental conditions affecting the teeth, gingiva, or periodontium and developing glaucoma after 1\u00a0year, 1-5\u00a0years, 5-15\u00a0years and cumulatively was detected in the FinnGen data, a population of 429,209 with at least 153,661 having a dental condition and 10,687 having POAG. Among the cohort of the DIGS ancillary study, the total bacterial count of the glaucoma group was significantly higher compared to that of controls (Mean\u2009\u00b1\u2009SD: 1.7\u2009\u00b1\u20091.4 and 0.9\u2009\u00b1\u20090.6, respectively, p\u2009<\u20090.03, two-sample t-test), while the species richness was significantly lower in glaucoma subjects compared to controls (p\u2009<\u20090.0005, Wilcoxon rank sum test). While the top taxa ordered by total abundance were similar between the two groups, mostly organisms associated with the commensal oral microbiome, there were some taxa linked with periodontal disease that were associated with glaucoma cases. However, the study was underpowered for the differences in top taxa between the glaucoma and non-glaucomatous control groups to achieve statistical significance (<\u20090.05) after adjusting for multiple comparison testing. A different bacterial abundance profile was detected between cases and controls by stepwise linear discriminant analysis. Inclusion of sleep apnea and the presence of cardiovascular disease as covariates in the analysis models did not significantly affect the results. Answers to the questionnaire about oral health and oral/dental history did not show a statistically significant difference between the two groups. The above findings suggest a potential link between oral health and glaucoma that may warrant further investigation.",
"42399494": "ID: 42399494\nTitle: Unhealthy fat distribution as a sex-specific predictor of declining hippocampus insulin sensitivity.\nAbstract: Impairments in peripheral glucose metabolism and reduced brain insulin sensitivity are linked to an increased risk of both metabolic and neurodegenerative diseases. Brain insulin resistance represents a shared pathological mechanism underlying these disorders. Notably, hippocampal insulin responsiveness declines with age and differs between men and women. This study aimed to identify clinically relevant metabolic predictors of hippocampal insulin sensitivity in the context of age and sex. In 260 non-diabetic participants (165 women, mean BMI 29.7\u00a0\u00b1\u00a06.2\u2009kg/m2, mean age 44.2\u00a0\u00b1\u00a016.6 years), functional MRI was performed before and after intranasal insulin administration to assess hippocampal insulin response. Metabolic phenotyping comprised laboratory assessments including oral glucose tolerance tests, whole-body MRI and 1H-MRS. In addition, participants were assigned to high- and low-risk prediabetes clusters using the T\u00fcbingen risk cluster tool. Prediabetes was defined as impaired fasting glucose and/or impaired glucose tolerance and/or elevated HbA1c. We used linear regression models to select the most relevant predictors, including interactions with sex and age. Fasting plasma glucose levels predicted lower hippocampal insulin response with age independently of sex (estimate 0.533, p=0.016). Significant interactions were present between age, sex and body fat distribution (waist-to-hip ratio [WHR]: estimate 0.233, p=0.010; visceral adipose tissue [VAT]: estimate 0.007, p=0.013; intrahepatic lipid content [IHL]: estimate 0.003, p=0.010). In women, higher WHR, VAT and IHL were predictors of lower hippocampal insulin responsiveness with increasing age. These effects remained significant after adjusting for BMI. Postmenopausal women showed lower hippocampal insulin responsiveness with higher WHR and IHL (p<0.05), and women in high-risk T\u00fcbingen prediabetes clusters also showed lower hippocampal insulin responsiveness than men (sex \u00d7 cluster type: estimate 0.39, p=0.02). The hippocampal insulin response did not correlate with hippocampal volume (p>0.05). Unhealthy body fat distribution was a sex-dependent predictor for decreased hippocampal insulin sensitivity with increasing age. Older women with high abdominal fat and/or those assigned to high-risk clusters were most vulnerable to impaired insulin responsiveness in the hippocampus. These findings may contribute to explaining sex differences in the development of type 2 diabetes and neurodegenerative diseases.",

The NLRP3 inflammasome, as a central mediator of inflammatory cascades, can, when excessively activated, promote neuroinflammation and glial polarization, induce neuronal death, disrupt the blood-brain barrier, suppress angiogenesis and neurogenesis, impair synaptic plasticity, and induce inflammaging, ultimately leading to neurodegeneration. Exerkines, including neurotrophic factors, adipokines, myokines, hepatokines, enzymes/coenzymes, metabolites, and miRNAs, can target the aberrant activation of the NLRP3 inflammasome, exerting neuroprotective effects. Exercise has attracted increasing attention for its benefits to brain health, as it can modulate the release and expression of numerous exerkines (such as BDNF, NGF, GDNF, APN, Chemerin, Apelin, Irisin, CX3CL1, HSP90, IGF-1, LCN2, SAA, SIRT1, lactate, and exosomal miRNAs), which, through the activation of specific kinases and downstream signaling pathways in the brain, precisely target the excessive activation of the NLRP3 inflammasome and thereby ameliorate neurodegeneration. This review summarizes and critically evaluates recent advances in the mechanistic roles of the NLRP3 inflammasome in the onset and progression of neurodegeneration, as well as in the molecular mechanisms by which exerkines regulate the NLRP3 inflammasome to ameliorate neurodegeneration, and in exercise interventions, providing a theoretical basis for the precise and targeted application of exercise in the prevention and treatment of neurodegeneration.",
"42401758": "ID: 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.",

Chronic activation of brain-resident immune cells, including microglia and astrocytes, in response to misfolded protein aggregates such as amyloid-\u03b2 and tau in AD and \u03b1-synuclein in PD, promotes maladaptive immune signaling, sustained cytokine release, and disruption of the blood-brain barrier (BBB). This chronic brain inflammation leads to synaptic dysfunction, neuronal loss and ultimately clinical deterioration. These processes are accompanied by disease-specific factors, such as inflammation of the gut-brain axis in PD and genetic modulators including APOE4, TREM2, and LRRK2. Furthermore, the development of fluid biomarkers together with neuroimaging techniques has improved early detection and monitoring of neuroinflammation leading to personalized therapeutic approaches. Clinical trials targeting microglial phenotypes, cytokine signaling, inflammasome activity, and genetic risk factors are emerging therapeutic strategies. Model limitations and heterogeneity of patients present challenges, but insights into neuroimmune interactions could provide a path forward for disease-modifying strategies. The present review aims to summarize new knowledge about the protective and detrimental aspects of neuroinflammation in AD and PD, providing an analysis on these developing prospects for targeted interventions toward slowing or stopping neurodegeneration.",

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.",
"42411493": "ID: 42411493\nTitle: Beyond Amyloid: Evolutionary and Immune-Metabolic Perspectives on Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is increasingly recognized as a multifactorial and systems-level disorder that extends beyond the classical amyloid cascade hypothesis. Rather than dismissing established concepts such as tau pathology, synaptic dysfunction, vascular compromise, mitochondrial abnormalities, and impaired proteostasis, emerging evidence suggests that these processes may interact dynamically with chronic immune activation, microbial signaling, and systemic metabolic stress. Recent studies examining the microbiome-gut-brain axis, chronic infection, innate immunity, and systemic immune-metabolic dysfunction have broadened the conceptual framework of AD pathogenesis. Importantly, amyloid-\u03b2 (A\u03b2) is now understood to possess evolutionarily conserved antimicrobial and immunomodulatory properties, suggesting that amyloid deposition may initially represent a protective host-defense response rather than solely a toxic pathological event. This perspective does not overturn the amyloid cascade model but instead reframes amyloid biology within a broader adaptive evolutionary context in which chronic or dysregulated activation becomes maladaptive during aging. The present opinion article integrates these converging concepts into a unified framework in which AD emerges from the prolonged interaction among immune responses, microbial exposures, metabolic disturbances, mitochondrial dysfunction, vascular injury, and age-associated failures in proteostatic resilience. This integrative interpretation seeks to humanize the disease process by viewing neurodegeneration not simply as isolated protein accumulation, but as the gradual exhaustion of ancient host-defense and energy-regulatory systems that were originally evolutionarily advantageous for survival.",

This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints. Collectively, these findings position phytochemicals as promising candidates for multi-target disease modification and the development of next-generation neurotherapeutic strategies.",
"42413884": "ID: 42413884\nTitle: Ageing-driven gastrointestinal variability in Parkinson's disease: implications for oral levodopa pharmacokinetics and formulation design.\nAbstract: Parkinson's disease is a distinctly age-associated neurodegenerative disorder in which oral levodopa remains the therapeutic foundation, particularly in older adults. Yet with advancing age, the reliability of oral therapy progressively declines not simply due to inadequate dosing, but because ageing reshapes the gastrointestinal environment on which drug absorption depends. This review integrates evidence spanning neuromuscular decline, epithelial barrier fragility, altered luminal chemistry, immune dysregulation, microbiome remodelling, and enteric neurodegeneration to explain how the ageing gut generates exposure instability. Delayed gastric emptying, inconsistent proximal intestinal delivery, microbial drug metabolism, and real-world administration constraints collectively amplify pharmacokinetic variability, producing erratic onset, fluctuating plasma profiles, and reduced therapeutic predictability. Using levodopa as a clinically established model system, we extend these insights to the broader challenge of ensuring reliable performance of oral therapies in ageing populations. We argue that therapeutic success in older adults depends less on maximizing mean bioavailability and more on stabilising exposure under heterogeneous physiological and practical conditions. Accordingly, the review integrates ageing-associated gastrointestinal decline, altered luminal and epithelial determinants of drug absorption, pharmacokinetic instability, and formulation design responses into a unified translational framework for ageing-aware oral therapy. By reframing levodopa failure as a consequence of ageing-driven gut-drug instability, this review proposes an ageing-aware formulation framework and identifies exposure-stability endpoints to guide the development and evaluation of physiologically resilient oral therapies for older adults.",

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, pharmacological interventions that precisely modulate the gut microbiota in DRE have not yet been fully explored. This review aims to propose a systematic hypothesis that Dipeptidyl peptidase-4 inhibitors (DPP-4is) may alleviate peripheral and central pathological damage by regulating the \"gut microbiota-short-chain fatty acids (SCFAs) -glucagon-like peptide-1 (GLP-1) axis\", thereby reducing susceptibility to DRE. Existing studies indicate that: (1)DPP-4is possess neuroprotective effects in experimental epilepsy models, partly by enhancing endogenous GLP-1 signaling. (2)DPP-4is have been reported to modulate gut microbiota composition and increase the abundance of SCFA-producing bacteria in metabolic diseases. (3)SCFAs can promote GLP-1 secretion by activating free fatty acid receptors (FFAR2/3) and improve intestinal barrier function and inflammatory status in metabolic and neurodegeneration disease. However, it remains unclear whether this pathway mediates the effects of DPP-4is in epilepsy. (4)Enhanced peripheral GLP-1 signaling can further influence central nervous system homeostasis, including enhancing inhibitory synaptic transmission, attenuating neuroinflammation, oxidative stress, and inhibiting neuronal apoptosis, thereby reducing susceptibility to seizures. By integrating cross-contextual evidence, we propose that DPP-4is may exert protective effects on DRE through gut microbiota-SCFAs-GLP-1 axis.",

This review aims to systematically elucidate the central role and multifaceted molecular mechanisms of mitochondrial dysfunction in the progression of AD. A comprehensive analysis of the existing literature was conducted, synthesizing findings from studies investigating mitochondrial involvement in AD pathology. The review focused on key mechanistic pathways, including energy metabolism deficits, oxidative stress, synaptic damage, mitochondrial dynamics, mitochondria-associated membranes (MAMs), mitophagy, and the gut-brain axis. The analysis revealed several critical mechanisms linking mitochondrial dysfunction to AD progression: (i) impaired mitochondrial energy metabolism, which establishes a causal relationship with oxidative stress and synaptic injury; (ii) dysregulation of mitochondrial fusion/fission dynamics, particularly the aberrant interactions of amyloid-beta (A\u03b2) and p-Tau with the fission protein Drp1 and the channel protein VDAC1; (iii) dysfunction of mitochondria-associated membranes (MAMs); (iv) defective mitophagy involving both the PINK1/Parkin pathway and receptor-mediated pathways; and (v) bidirectional crosstalk between mitochondria and the gut-brain axis. These interconnected pathways converge to amplify neuroinflammation and neuronal death. Accumulated evidence positions mitochondrial dysfunction as a critical hub that integrates A\u03b2/Tau pathology, neuroinflammation, and neuronal loss, thereby perpetuating a self-sustaining vicious cycle in AD. Targeting mitochondrial bioenergetics, dynamics, quality control, and the mitochondria-inflammation axis offers substantial therapeutic promise. Emerging small molecules such as SS31 and DDQ have demonstrated protective effects in preclinical models. Future investigations should prioritize mechanistic dissection and translational research to facilitate the clinical development of mitochondria-targeted therapies for AD.",

This review introduces the history of hypothermia in medicine first, followed by a description of cellular mechanisms behind its neuroprotective effects observed in animal studies and some clinical studies. The next section focuses on current cooling approaches/devices, as well as cooling parameters recommended by researchers and clinicians to maximize the benefits of hypothermia. Animal and clinical studies of implementing hypothermia for spinal cord and brain tissue injury are presented next. The outcomes in treating conditions like traumatic brain injury (TBI), spinal cord injury (SCI), stroke, and cardiopulmonary issues will be discussed in detail. The review also examines the risks and benefits of hypothermia, supported or disputed by clinical studies. Contributions from bioengineers in the research field are presented in the last section, with details of cooling device design and theoretical simulations. Ultimately, the review highlights that successful hypothermia treatment hinges on achieving targeted tissue cooling quickly after injury, with mild hypothermia often being proven as effective as deeper cooling, provided a slow rewarming rate is implemented.",

Our recent research has revealed the Blautia faecis and Blautia massiliensis exhibit opposing associations with cognitive function in children with Down syndrome clinically characterized by cognitive dysfunction. However, the role and mechanisms of Blautia faecis and Blautia massiliensis in cognitive function remain unknown. Therefore, we gavaged C57BL/6 male mice with commercially available Blautia faecis and Blautia massiliensis for 3\u202fweeks and assessed cognitive function using the novel object recognition and Y-maze test. Blautia faecis administration impaired cognitive performance, whereas Blautia massiliensis treatment improved it, with these effects observed predominantly in the absence of antibiotic pretreatment. Furthermore, we observed that administration of Blautia faecis increased the number of microglia, resulting in a twofold increase in cell count relative to WT control. Hippocampal pro-inflammatory cytokines were significantly upregulated in the Blautia faecis group, while Blautia massiliensis suppressed these neuroinflammatory responses. Notably, Blautia massiliensis produces approximately six times more acetate than Blautia faecis. Consequently, our findings indicate that Blautia massiliensis enhances cognitive function whereas Blautia faecis impairs it, and we speculate that differential acetate production may contribute to these opposing effects.",

This review systematically addresses the ligand-specific duality of AhR signaling in cognitive health, comparing the predominantly neurotoxic signaling driven by environmental polycyclic aromatic hydrocarbons (PAHs) with the predominantly neuroprotective signaling mediated by gut microbiota-derived tryptophan metabolites. However, this dichotomy is context-dependent rather than absolute. PAHs activate AhR in a sustained, high-affinity manner, engaging downstream NF-\u03baB neuroinflammation, NLRP3 inflammasome activation, oxidative stress, synaptic dysfunction, and transgenerational epigenetic alterations. In contrast, microbiota-derived metabolites such as indole-3-propionic acid (IPA) and kynurenic acid (KYNA) elicit transient, low-affinity AhR activation that engages cell-type-specific programs promoting anti-inflammatory responses, neurogenesis, blood-brain barrier integrity, and neuronal homeostasis. Critically, the outcome of AhR activation is modulated by ligand pharmacokinetics, cell-type identity, temporal dynamics of receptor engagement, and tissue-specific co-factor availability. These contextual variables determine whether AhR functions as a driver of neurodegeneration or a guardian of cognitive resilience. We further examine the divergent roles of AhR in Alzheimer's and Parkinson's diseases, where the balance between detrimental and protective ligands determines disease progression. Finally, we discuss therapeutic strategies targeting the AhR-gut-brain axis, including dietary modulation, probiotic interventions, and selective AhR modulators. Understanding the context-dependent outcomes of AhR activation provides a framework for developing precision approaches to preserve cognitive function and prevent neurodegeneration.",
"42425421": "ID: 42425421\nTitle: Dietary bioactive compounds and inflammaging: Pro-inflammatory triggers and geroprotective countermeasures.\nAbstract: Chronic low-grade inflammation (\"inflammaging\") is a key driver of age-related pathologies including cardiovascular disease, neurodegeneration, and metabolic syndrome. Diet plays a dual role in modulating this process, acting both as a source of pro-inflammatory molecular patterns and as a delivery system for geroprotective compounds. This review examines the pro-inflammatory dietary components (advanced glycation end products, lipid peroxidation products, oxysterols, trans fats, and microbiome-derived metabolites) that activate pattern recognition receptors and trigger inflammatory cascades, as well as the anti-inflammatory mechanisms of bioactive dietary compounds including polyphenols, omega-3 fatty acids, carotenoids, vitamins, and essential microelements. Evidence from cellular, animal, and clinical studies is synthesized to evaluate dietary interventions for healthy aging. PubMed and Google Scholar were systematically searched from inception through November 2025, with evidence quality and translational limitations critically appraised throughout. Pro-inflammatory dietary components activate nuclear factor-kappa B pathways, while geroprotective compounds demonstrate potent anti-inflammatory properties through multiple mechanisms: polyphenols (quercetin, EGCG, resveratrol, curcumin) inhibit pro-inflammatory signaling and activate sirtuin and Nrf2 pathways; omega-3 fatty acids reduce pro-inflammatory eicosanoids and increase specialized pro-resolving mediators; carotenoids, vitamins, and microelements (selenium, zinc, magnesium) suppress oxidative stress and modulate immune function. These dietary geroprotectors reduce inflammatory biomarkers in cellular and animal models, while clinical evidence in humans remains largely restricted to biomarker and healthspan-related endpoints rather than demonstrated lifespan extension. Optimized nutrition-emphasizing fruits, vegetables, legumes, nuts, whole grains, and omega-3-rich foods while limiting refined sugars and trans fats-represents a cornerstone intervention for mitigating inflammaging and promoting healthy longevity, with the Dietary Inflammatory Index providing a translational framework for implementation.",
"42427525": "ID: 42427525\nTitle: Notch Signaling Reprograms Glial Lipid Metabolism to Promote Hypoxia Resistance.\nAbstract: Hypoxia poses a major threat to the developing nervous system, where high metabolic demand is required to support brain growth, glial and neuronal maturation, and function. Although glial cells are essential for maintaining neural homeostasis under stress, how specific glial subtypes remodel metabolism to promote hypoxia tolerance remains poorly understood. Here, we identify a Notch-dependent lipid metabolic program in excitatory amino acid transporter 1 (Eaat1)-positive glia that supports hypoxia adaptation in the developing Drosophila larval brain. Using stimulated Raman scattering (SRS) microscopy combined with deuterium-labeled metabolic probes, we visualized substrate-specific metabolic activity in vivo at subcellular resolution. In control, non-adapted flies, we found that acute hypoxia markedly increased de novo lipogenesis in Eaat1-positive glia. In flies adapted to chronic hypoxia, Eaat1-positive glia exhibited a pre-programmed metabolic shift, characterized by reduced glucose-derived lipogenesis and enhanced acetate-derived lipid synthesis. Constitutive activation of Notch signaling in Eaat1-positive glia was sufficient to phenocopy this acetate-favored lipogenic state, suggesting that Notch promotes metabolic plasticity under oxygen-limited conditions. To define the transcriptional programs associated with this response, we performed single-nucleus RNA sequencing (snRNA-seq) of the developing Drosophila central nervous system and mapped Eaat-1expressing cell populations across hypoxia and Notch activation. Notch activation reshaped hypoxia-associated transcriptional responses and counteracted metabolic suppression caused by low oxygen. Together, our findings identify Eaat1-positiveglia as a metabolically adaptive glial population and reveal a conserved Notch-regulated mechanism that rewires lipid metabolism to support hypoxia tolerance in the developing brain. These results provide insight into glial metabolic strategies that may be relevant to hypoxia-associated neurological conditions, including neonatal hypoxic-ischemic brain injury and ischemic stroke.",
"42437581": "ID: 42437581\nTitle: Peripheral nerve injury-induced upregulation of acyl-CoA synthetase 2 contributes to neuropathic pain via mediating microglial autophagy disruption in the spinal dorsal horn.\nAbstract: Acyl-CoA synthetase 2 (ACSS2), by producing acetyl-coenzyme A from acetate in the nucleus, facilitates histone acetylation and regulates gene expression. However, the role of ACSS2 in neuropathic pain remains unclear. Herein, we found that lumbar 5 spinal nerve ligation (SNL) increased ACSS2 expression predominately in microglia of the spinal dorsal horn. This increase was accompanied by elevated histone H3K27 acetylation (H3K27ac), enhanced raptor expression, activated mTORC1/TFEB signaling, raised p62, and reduced LC3II/LC3I ratio. Repeated intrathecal or intravenous injections of ACSS2 inhibitor (ACSS2i) partially prevented development of, and reversed established, neuropathic pain in male and female rats. Microglia-specific AAV-F4/80-ACSS2 shRNA injection into L5 spinal dorsal horn alleviated SNL-induced pain hypersensitivity, counteracted the increase in H3K27ac and rescued mTORC1/TFEB signaling-mediated autophagy impairment. SNL-enhanced binding of SP1, a transcriptional regulator of raptor, and the elevation of H3K27ac at the raptor promoter were inhibited by AAV-F4/80-ACSS2 shRNA. The increases of IL-1\u03b2 and TNF-\u03b1 production after SNL were also reversed by these interventions. Microglia-specific Acss2 knockout (Acss2cKO) mitigated SNL-induced abnormal pain, and prevented microglial autophagy disruption in male and female mice. ACSS2i treatment decreased H3K27ac, reduced SP1 binding with raptor promoter, and restored autophagy disruption in cultured BV2 cells following LPS stimulation. In addition, knockdown of ACSS2 specifically in neurons or astrocytes partially reduced pain following SNL. Collectively, our findings suggest that the peripheral nerve injury-induced upregulation of ACSS2 in the spinal dorsal horn contributes to neuropathic pain might partially through regulating raptor expression and subsequently activating mTORC1/TFEB signaling-mediated microglial autophagy disruption.",
"42450024": "ID: 42450024\nTitle: Fenfluramine Attenuates Retinal Microglial Activation but Does Not Rescue Structural and Vascular Deficits in a Rat Model of Dravet Syndrome.\nAbstract: Dravet syndrome (DS) is a severe developmental and epileptic encephalopathy caused by SCN1A haploinsufficiency. While brain pathology has been extensively studied, the retina remains underexplored. This study investigated retinal structural, functional, vascular, and cellular changes in a Scn1a+/- rat model of DS. Anatomical quantification revealed thinning of the retinal nerve fiber layer and thickening of the outer plexiform layer. Electroretinography (ERG) showed selectively reduced oscillatory potential amplitudes, suggesting dysfunction of neurovascular coupling. Consistent with these findings, immunohistochemistry demonstrated aberrant vascular morphology, including increased vessel curvature and reduced branching density. In addition, we observed robust microglial activation in the outer and inner plexiform layers; however, astrocyte morphology remained largely unchanged. Fenfluramine, an approved anti-seizure drug for DS, attenuated microglial activation but failed to rescue retinal structural or vascular deficits, indicating a dissociation between its anti-inflammatory and disease-modifying effects. Our findings suggest that multimodal retinal assessment could serve as a noninvasive biomarker platform for monitoring disease progression and therapeutic response in DS.",

Using a scopolamine-induced mouse model of acute cognitive impairment (male ICR mice, n = 10/group), we demonstrated that daily administration of MsA (10, 20, and 30 mg/kg/day) for 5 weeks significantly ameliorated cognitive performance in novel object recognition and Morris water maze tests. At the optimal dose (30 mg/kg/day), MsA suppressed hippocampal microglial activation, reduced pro-inflammatory cytokines (IL-6, IL-1\u03b2, TNF-\u03b1), and attenuated oxidative stress by decreasing malondialdehyde (MDA) while restoring superoxide dismutase (SOD) and glutathione (GSH) levels. MsA also strengthened intestinal barrier integrity (ZO-1, occludin) and significantly altered the gut microbiota, notably increasing the beneficial genus Dubosiella. Brain metabolomics indicated that MsA reversed scopolamine-induced metabolic disturbances, mainly restoring phospholipid balance. Correlation analysis demonstrated a strong gut-brain connection, with Dubosiella abundance positively associated with neuroprotective phospholipids and negatively with stress markers. Furthermore, fecal microbiota transplantation from MsA-treated donors successfully replicated these behavioral improvements in recipient mice, underscoring the functional involvement of the reshaped microbiome rather than a simple autonomous recovery. These results suggest that MsA alleviates AD-like cognitive impairment by reducing neuroinflammation and oxidative stress through microbiota remodeling, enhancing the intestinal barrier, and modulating the Dubosiella-associated gut-metabolite-brain axis, making MsA a promising multi-target nutraceutical for ameliorating AD-like cognitive deficits.",
"42451206": "ID: 42451206\nTitle: KetoFLEX 12/3 Diet and Cognitive Health: A Precision-Nutrition Perspective on Mechanisms, Emerging Evidence, and Future Directions.\nAbstract: Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder characterized by impaired glucose metabolism, mitochondrial dysfunction, inflammation, oxidative stress, and progressive cognitive decline. Because currently available pharmacological therapies provide only modest symptomatic benefit, nutrition-based interventions are increasingly being explored as complementary strategies for supporting brain metabolism and cognitive resilience. The KetoFLEX 12/3 dietary pattern, developed within the ReCODE (Reversal of Cognitive Decline) program, is a plant-rich, mildly ketogenic nutrition and lifestyle framework that integrates low-glycemic nutrition, time-restricted eating, and personalized metabolic optimization. The diet emphasizes deeply pigmented non-starchy vegetables, extra-virgin olive oil, nuts and seeds, omega-3-rich seafood, and minimally processed foods while limiting refined carbohydrates, sugars, processed foods, and selected grains and dairy products. Emerging mechanistic and clinical evidence suggests that KetoFLEX 12/3 may influence several pathways relevant to AD pathophysiology, including insulin signaling, mitochondrial bioenergetics, neuroinflammation, oxidative stress, autophagy, detoxification pathways, and gut-brain axis function. Observational findings from ReCODE-related studies have reported improvements in metabolic parameters, mood-related outcomes, cognitive measures, and brain volumetrics in participants adhering to multimodal precision-medicine interventions incorporating the KetoFLEX principles. Compared with traditional dietary models such as the Mediterranean or MIND diets, KetoFLEX 12/3 places greater emphasis on mild nutritional ketosis, meal timing, and metabolic personalization based on factors such as ApoE genotype and insulin sensitivity. The objective of this Perspective is to examine the mechanistic rationale, emerging evidence, limitations, and future research priorities for KetoFLEX 12/3 as a precision-nutrition framework for cognitive health in AD. Although much of the current evidence remains mechanistic, observational, or derived from multimodal intervention studies, the framework offers a biologically plausible precision-nutrition model that may inform future research and clinical investigation in cognitive decline.",
"42452254": "ID: 42452254\nTitle: Comparative Study of Young and Mature Dendropanax morbifera Leaves: Superior Neuroprotective Efficacy of Young Leaves Through Enhanced Anti-Inflammatory and Metabolic Modulation.\nAbstract: Neuroinflammation, driven by microglial activation and oxidative stress, is a key pathological feature of various neurodegenerative diseases. Dendropanax morbifera L\u00e9veille (DM) is a medicinal plant known for its diverse pharmacological activities; however, the influence of leaf developmental stage on its neuroprotective potential remains poorly understood. In this study, we compared the phytochemical profiles of young DM (YDM) and mature DM leaves and evaluated their effects on neuronal metabolism and microglia-mediated neuroinflammation. HPLC analysis revealed that YDM contained approximately 2.4-fold higher levels of chlorogenic acid than DM, while DM exhibited higher quercetin content. In differentiated N2A neuronal cells, YDM treatment significantly upregulated the expression of key metabolic and mitochondrial regulators, including PGC-1\u03b1, PPAR\u03b3, and CPT2, suggesting enhanced mitochondrial and metabolic regulatory signaling related to biogenesis and fatty acid \u03b2-oxidation. Under inflammatory conditions, YDM more potently suppressed the secretion of pro-inflammatory cytokines (IL-6 and TNF-\u03b1) in LPS-stimulated BV2 microglia compared to DM. Furthermore, in N2A cells treated with BV2-conditioned medium, both extracts effectively mitigated reactive oxygen species production and restored brain-derived neurotrophic factor expression. These findings demonstrate that leaf age is a critical determinant of the phytochemical composition and biological activity of DM. Our results suggest that chlorogenic acid-rich YDM preparations may offer superior therapeutic advantages in targeting neuroinflammatory and metabolic dysregulation in the central nervous system.",

Male C57BL/6 mice (8 weeks old) were randomly assigned to the control, PD model, and PD + EA groups. PD was induced by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), while control mice received saline. EA was administered to the motor cortex once daily for five consecutive days in the PD + EA group, whereas PD model mice were restrained without receiving EA stimulation. Behavioral assessments were performed to evaluate motor function and nociceptive sensitivity. Immunohistochemistry, immunofluorescence, and western blot analyses were used to quantify tyrosine hydroxylase (TH), ionized calcium-binding adapter molecule 1 (Iba-1), NLRP3 inflammasome components, and inflammatory cytokines in key brain regions. Compared with control mice, PD model mice showed reduced motor performance and heightened nociceptive sensitivity, accompanied by a decrease in TH-positive neurons and an increase in Iba-1-positive microglia in both the substantia nigra and amygdala. EA significantly improved motor performance and increased pain thresholds. Moreover, EA preserved TH-positive neurons, suppressed microglial activation, and downregulated the expression of NLRP3, ASC, caspase-1, interleukin (IL)-1\u03b2, IL-6, and tumor necrosis factor (TNF)-\u03b1 in the amygdala. These findings suggest that EA alleviates PD-related pain, possibly by modulating microglial activation and NLRP3 inflammasome signaling in the amygdala, thereby reducing neuroinflammation.",

Here, we report a biogenic selenium nanoparticle (Se-NP) platform derived from mussel tissue and demonstrate its nano-enabled neuroprotective efficacy in a rotenone-induced zebrafish model of Parkinsonian neurotoxicity. Selenium was extracted from the tissue of Perna viridis (mussel) and used for the biogenic synthesis of Se-NPs through a green reduction approach under controlled conditions. The mussel-derived Se-NPs exhibited high redox-buffering capacity, enabling efficient attenuation of rotenone-induced oxidative stress, lipid peroxidation, and nitric oxide accumulation. Se-NP treatment preserved dopaminergic neuronal architecture, reduced microglial activation, and maintained gut epithelial integrity, indicating coordinated neuro-intestinal protection. Mechanistically, Se-NPs activated NRF2-driven antioxidant signaling through upregulation of NFE2L2a and HMOX1a and suppression of KEAP1a, thereby restoring endogenous antioxidant defences. At the neurovascular interface, Se-NPs enhanced blood-brain barrier integrity by upregulating tight junction proteins Claudin-5a and ZO-1, linking redox regulation to barrier stabilization. Notably, Se-NPs restored dopaminergic gene expression, modulated inflammatory signaling pathways, and normalized gut-associated microbial markers, thereby supporting nano-mediated regulation of the gut-brain axis. Collectively, this study establishes biogenic Se-NPs as a multifunctional nanotherapeutic that integrates antioxidant signaling, neurovascular protection, and gut-brain axis modulation to counteract rotenone-induced neurodegeneration, highlighting their potential as a nano-enabled strategy for PD intervention.",

The liver-brain axis acts as a key mediator of brain dysfunction and warrants investigation in lifestyle-induced brain aging. To elucidate how the liver-brain axis mediates lifestyle-triggered neurovascular resilience disturbance and associated brain aging phenotypes, and identify effective anti-aging intervention targets. A combination of in vivo animal models, multi-omics analyses, computational simulation, brain organoid experiments, and molecular biology techniques to explore the mechanism of liver-brain axis mediates lifestyle-triggered neurovascular resilience disturbance and associated brain aging phenotypes and verify the efficacy of Bazi Bushen capsule (BZBS) intervention. A mouse model established using a combined high-fat/high-sugar diet and circadian disruption (HFHS/CD). Cognitive function and anxiety-like behaviors were evaluated. Multi-omics analyses were performed, and liver-brain axis/hypoxanthine signals were verified via computational simulation and brain organoids. Active ingredient targets were identified by molecular docking, drug affinity responsive target stability, and validated by biolayer interferometry. HFHS/CD induced cognitive decline and anxiety accompanied by apparent brain aging-related phenotypes, which were alleviated by nicotinamide mononucleotide (NMN) and BZBS. Dysregulated hepatic hypoxanthine metabolism under metabolic stress contributed to neurovascular homeostasis disturbance, characterized by compromised BBB integrity and excessive microglial activation. In vitro experiments further indicated that elevated hypoxanthine levels were involved in endothelial senescence, potentially through P2X7-dependent suppression of NRF2-governed glutathione metabolism. BZBS acted through multiple targets: imperatorin/isopimpinellin regulated hepatic purine nucleoside phosphorylase (PNP)/hypoxanthine phosphoribosyltransferase 1 (HPRT1) to reduce hypoxanthine, while osthole/schizandrin A maintained endothelial integrity. Aberrant hypoxanthine metabolism induced by unhealthy lifestyles may disrupt neurovascular homeostasis through the liver-brain axis and contribute to the occurrence of brain aging phenotypes. BZBS improves age-related brain dysfunction by targeting hypoxanthine metabolism and protecting endothelial function, representing a promising intervention.",
"42457059": "ID: 42457059\nTitle: Ischemia-induced p300-dependent histone lactylation activates an AP-1-SPP1 program in microglia to exacerbate ischemic brain injury.\nAbstract: Cerebral ischemia causes profound metabolic disruption, but how ischemia-associated metabolites reshape microglial chromatin and inflammatory function remains unclear. Here we identify histone lactylation as an epigenetic mechanism linking ischemic metabolic stress to pathogenic microglial activation. In transient middle cerebral artery occlusion mice and oxygen-glucose deprivation/reperfusion models, ischemic stress robustly increased H3K18la and H4K12la in microglia. CUT&Tag profiling showed widespread remodeling of both lactylation landscapes, with gained peaks preferentially associated with inflammatory, chemotactic, migratory and efferocytic programs. Integration with microglial RNA sequencing identified a concordantly activated gene network enriched for TNF, NF-\u03baB, IL-17 and cytoskeletal regulatory pathways, with Spp1 emerging as a prominent effector linked to ischemia-induced lactylation. Motif enrichment and locus-level analyses implicated AP-1-associated regulatory elements, and ChIP-qPCR confirmed increased H3K18la and H4K12la at Fos and Spp1 regulatory regions after ischemia-like stress. Mechanistically, p300 depletion or inhibition reduced H3K18la/H4K12la accumulation, impaired AP-1-associated promoter engagement, and suppressed Fos, Spp1 and chemokine induction. Non-lactylatable H3K18R and H4K12R mutants attenuated Fos-Spp1 transcription and microglial migration, supporting cooperative regulation by these two marks. Functionally, microglia-specific Spp1 deletion reduced inflammatory microglial activation, neuronal apoptosis and long-term neurological deficits after ischemic injury. Pharmacological inhibition of p300 or AP-1, and SPP1 neutralization, similarly limited neuroinflammation and improved sensorimotor and cognitive recovery. Together, our findings define a lactate-p300-AP-1-SPP1 axis that couples ischemic metabolism to microglial chromatin remodeling and post-stroke neuroinflammatory injury.",

Enavogliflozin, a novel sodium-glucose cotransporter 2 (SGLT2) inhibitor, has recently been demonstrated to exert neuroprotective effects. However, whether enavogliflozin can ameliorate motor behavioral deficits in Parkinson's disease currently remains unclear. To this end, this study aimed to investigate the neuroprotective effects of enavogliflozin on Parkinson's disease and explore its underlying molecular mechanisms. We established a Parkinson's disease model using rotenone-induced C57BL/6 mice (1.5\u202fmg/kg/d, 3 weeks, i.p.) to investigate the neuropharmacological modulation effects of enavogliflozin treatment (0.1 and 1\u202fmg/kg/d, 3 weeks, p.o., 2\u202fh after rotenone injection) on Parkinson's disease from the perspectives of motor behavioral evaluation, pathological changes, oxidative stress, neuroinflammation, and SIRT1/PINK1/Parkin signaling pathways in specific brain regions. The results revealed that enavogliflozin alleviated neuropathological alterations of the substantia nigra, upregulated tyrosine hydroxylase and dopamine transporter expression in nigrostriatal dopaminergic neurons, and improved motor behavioral deficits. Administration of enavogliflozin further significantly reduced the levels of inflammatory cytokines (IL-6 and TNF-\u03b1), microglial activation, and oxidative damage in rotenone-induced Parkinson's disease mice. Moreover, we found that enavogliflozin activated PINK1/Parkin-mediated mitophagy by SIRT1 signaling pathway. In conclusion, enavogliflozin ameliorates motor dysfunction in rotenone-induced Parkinson's disease mice by attenuating oxidative stress, inhibiting neuroinflammation, and activating SIRT1/PINK1/Parkin pathway. These findings support a neuroprotective and preventive role for enavogliflozin in Parkinson's disease.",
"42457861": "ID: 42457861\nTitle: Aspirin alleviates long-term high-fat diet-induced depressive-like behavior in male mice via suppressing arachidonic acid-mediated microglial activation and neuroinflammation.\nAbstract: While Western dietary patterns are increasingly linked to neuropsychiatric disorders, the causal mechanisms by which chronic high-fat diet (HFD) contributes to depression remain elusive. Here, we demonstrate that prolonged (\u2009\u2265\u200910 weeks) HFD exposure in mice robustly induces depressive-like behaviors, phenocopying chronic stress models. Integrating multi-omics and targeted lipidomics, we reveal that HFD-induced behavioral deficits are underpinned by gut microbiota dysbiosis and a profound disruption of polyunsaturated fatty acid (PUFA) homeostasis. This disruption is characterized by a surge in pro-inflammatory \u03c9-6 metabolites, particularly arachidonic acid (AA), alongside a concomitant reduction in anti-inflammatory \u03c9-3 metabolites. These lipid perturbations strongly correlate with marked microglial activation and elevated pro-inflammatory cytokine levels (IL-6, TNF-\u03b1, CCL2) in the prefrontal cortex and hippocampus. Functionally, AA supplementation alone was sufficient to recapitulate depressive-like behaviors in vivo and, through neuron-microglia co-culture assays, directly induce pro-inflammatory microglial activation, NF-\u03baB pathway upregulation, and subsequent synaptic impairment in vitro. Critically, therapeutic intervention with aspirin, a dual COX-1/COX-2 inhibitor, effectively reversed HFD-induced behavioral deficits. This protection was mediated by a dual mechanism: directly inhibiting microglial hyperactivation and normalizing the neuroinflammatory milieu by suppressing the biosynthesis of pro-inflammatory \u03c9-6-derived prostanoids, including AA and 12-HETE. Collectively, our findings identify AA as a critical etiological link between HFD and neuroinflammation, establishing a mechanistic framework for \"metabolic depression.\" The profound therapeutic efficacy of aspirin validates the AA metabolic pathway, specifically COX-1/COX-2, as a promising and targetable node for intervention, offering translational insights for the burgeoning field of nutritional psychiatry.",

Here, we aimed to investigate the effects of formyl peptide receptor 2 (FPR2), a key regulator of innate immunity and inflammation, on lipopolysaccharide (LPS)-induced depression-related behaviors in mice after intraperitoneal administration, and to elucidate its regulatory mechanisms in microglia. FPR2 knockout (Fpr2-/-) significantly attenuated LPS-induced depressive and anxiety-like behaviors in mice. LPS markedly increased FPR2 expression in microglia of the prefrontal cortex (PFC) and hippocampus, while only a minimal increase was observed in neurons. FPR2 deficiency alleviated LPS-induced microglial activation and reduced neuronal synaptic alterations. RNA sequencing and validation experiments confirmed that FPR2 deletion substantially decreased LPS-induced microglial NLRP3 inflammasome activation and IL-1\u03b2 levels in the brain. Mechanistically, FPR2 regulated downstream NLRP3 activation by modulating CSF1, and FPR2/CSF1 activation was governed by its upstream ligand, serum amyloid A (SAA). Analysis of public clinical datasets revealed that SAA1 levels were significantly upregulated in the orbital ventral PFC of patients with major depressive disorder (MDD) and in the plasma of patients with late-life depression. These findings demonstrate that the SAA/FPR2/CSF1/NLRP3 pathway mediates LPS-induced depressive-like behaviors by regulating microglial activation and neuroinflammation.",

Flavonoids are abundant in human diet and possess significant neuroprotective potential. We screened a library of 339 flavonoid compounds. Daidzein (DAI) was identified as the lead compound. Subsequently, in rats subjected to chronic restraint stress (CRS), DAI administration effectively ameliorated depression-like behaviors, and attenuated hippocampal histopathological damage. Network pharmacology and molecular docking analyses suggested that ERK-related signaling may be involved in the protective effects of DAI, and molecular dynamics simulations supported the stability of the DAI-ERK2 complex. Furthermore, DAI activated the ERK/CREB/BDNF signaling cascade, an effect that was partially reversed by ERK inhibitor intervention. Notably, DAI also enhanced dendritic complexity and spine density in hippocampus. In summary, our study demonstrates that DAI alleviates stress-induced synaptic plasticity damage through the ERK/CREB/BDNF signaling pathway.",

Astrocytes actively regulate synaptic plasticity and memory through dynamic volume transients. Our previous research identified several key molecules, including TREK-1, TRPA1, and Best1 ion channels, as well as the gliotransmitter BDNF, as critical components of astrocytic volume transients. However, the precise mechanisms by which these volume transients influence synaptic plasticity and memory remain poorly understood. In this study, we investigate the roles of TREK-1 and TRPA1 in astrocytic volume dynamics and their downstream effects. Our findings, based on intrinsic optical signal imaging, electrophysiology, and behavioral assays, support a model in which neuronal stimulation induces astrocytic swelling, initiated by K+ uptake through TREK-1 channels and regulated by Ca2+ influx via TRPA1 channels. This swelling is closely associated with short- and long-term potentiation (LTP), and exogenous BDNF restores LTP under conditions of calcium sequestration during astrocytic calcium clamping experiments. Disruption of ion channels associated with astrocytic volume transients leads to significant impairments in spatial memory, as demonstrated by deficits in object-place recognition and passive avoidance tasks. Moreover, these channels contribute to the regulation of synaptic plasticity. These findings implicate astrocytic volume transients and BDNF as pivotal modulators of synaptic plasticity and memory, as well as potential therapeutic targets for addressing memory dysfunctions.",

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.",

Micro- and nanoplastics (MNPs), ubiquitous environmental pollutants generated from plastic degradation, have recently emerged as potential biological stressors capable of entering the human body and accumulating in sensitive tissues, including the brain. Due to their small size, environmental persistence, and capacity to carry toxic additives and environmental contaminants, these particles can induce oxidative stress, impair mitochondrial and lysosomal function, and activate both innate and adaptive immune responses. This review summarizes current evidence linking microplastic exposure to neuroinflammatory processes relevant to PD, with a particular focus on microglial activation, astrocyte reactivity, peripheral immune involvement, and dysfunction of the gut-brain axis. Although a direct causal relationship between MNPs and PD has yet to be established, and direct human epidemiological evidence linking MNP exposure to PD is currently absent, the immunotoxic and neuroinflammatory effects of these particles suggest that they may contribute to disease susceptibility and progression. Elucidating the interactions between MNPs and neuroimmune pathways may help refine current frameworks linking environmental exposure, neuroimmune dysfunction, and PD susceptibility.",

Alterations in gut microbiota and inflammation are key pathophysiological contributors. Elucidating the genetic basis and the role of cytokines can provide insights into mechanisms linking gut microbial composition to neurodegeneration. Using aggregated statistics from five large-scale Genome-Wide Association Studies (GWAS) on Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple sclerosis, and amyotrophic lateral sclerosis, bidirectional two-sample Mendelian Randomization (MR) was used to examine the associations. A two-step multivariable Mendelian randomization approach incorporates data from 91 cytokines to explore potential mediators. The study reveals 18 positive and 17 negative effects between gut microbiota and NDDs, as well as 10 positive and 10 negative effects between cytokines and NDDs. Remarkably, mediation analysis identified a causal pathway, with evidence that plasma neurturin levels partially mediate the association from genus Ruminococcus2 to multiple sclerosis, with a mediation proportion of 19.19% (OR = 1.038, 95% CI = 1.001-1.086, P = 0.044). No pleiotropy or heterogeneity was detected. These MR findings provide compelling evidence for a genetically anchored gutimmune-brain network in NDDs, with cytokines as intermediates. Bidirectional effects highlight disease-specific microbial signatures and inflammatory contexts. The Ruminococcus2-neurturin pathway in multiple sclerosis may offer mechanistic specificity, aligning with neurotrophic and anti-inflammatory signaling pathways. This study emphasizes the importance of gut microbiota alterations in NDDs and explores inflammation's partial intermediary role. The findings suggest potential targets for personalized neurodegeneration prevention strategies.",

Current medications are largely palliative, underscoring the need for alternative therapeutic strategies. Drug repurposing offers a cost-effective and time-efficient approach by leveraging established safety profiles. Here, we screened the U.S. Food and Drug Administration-approved drug library using two in vitro PD models: 1-methyl-4-phenylpyridinium (MPP+)-induced primary cortical neurons and lipopolysaccharide (LPS)-induced BV2 microglial cells. Proteomic alterations following prasugrel treatment were profiled using Ingenuity Pathway Analysis. Neuroprotective effects were validated by biochemical assays and further confirmed in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model. We found that prasugrel, an antiplatelet drug used for acute coronary syndrome, exhibited significant neuroprotective and anti-inflammatory effects. It reduced the expression of apoptosis- and inflammation-related proteins, inhibited mitogen-activated protein kinase (MAPK)-mediated neuronal death and suppressed nuclear factor kappa B (NF-\u03baB)-dependent inflammatory signaling. In vivo, prasugrel administration preserved dopaminergic neurons and improved motor performance in MPTP-treated mice. These findings demonstrate that prasugrel mitigates neuronal apoptosis and microglial activation through modulation of MAPK and NF-\u03baB signaling pathways, supporting its development as a repurposed therapeutic candidate for PD.",
"42463907": "ID: 42463907\nTitle: The Exercise-CTSS-AD Axis: a novel framework for understanding exercise-induced neuroprotection in Alzheimer's disease.\nAbstract: Disease-modifying therapies for Alzheimer's disease (AD) targeting amyloid-\u03b2 and tau have consistently failed, highlighting the urgent need for innovative therapeutic strategies. Cathepsin S (CTSS), a lysosomal cysteine protease upregulated in AD, functions as a \"multifaceted disruptor\" that interconnects neuroinflammation, blood-brain barrier (BBB) dysfunction, and A\u03b2 metabolic dysregulation. Although exercise is a validated non-pharmacological intervention that mitigates AD pathology, its multi-target molecular mechanisms remain elusive. Here, we propose and substantiate the \"Exercise-CTSS-AD Axis\" hypothesis, positing that exercise confers neuroprotection by suppressing CTSS through synergistic anti-inflammatory, anti-aging, and metabolic regulatory pathways. Exercise-induced myokines and clearance of senescent cells inhibit CTSS transcription, while AMPK-TFEB axis activation enhances lysosomal function to repress CTSS enzymatic activity. This systemic CTSS suppression preserves BBB integrity, ameliorates microglia-driven neuroinflammation, and restores A\u03b2 homeostasis by reducing production and enhancing clearance. Our framework provides a unifying molecular explanation for the pleiotropic benefits of exercise, positions CTSS as a quantifiable biomarker for personalized exercise regimens, and supports an innovative combinatorial strategy: \"Exercise\u2009+\u2009low-dose CTSS inhibitors\" as a disease-modifying therapy for AD.",

While astrocyte-derived exosomes (ADEs) offer neuroprotection, their role in protecting retinal microvasculature is unclear. This study investigates ADEs' effects on retinal microvascular endothelial cells (RMECs) in RIR. ADEs were isolated from astrocytes. Mouse RIR and cellular oxygen-glucose deprivation/reoxygenation (OGD/R) models were used. We assessed ADEs' impact on retinal microcirculation, microglial activation, and RMEC function. The roles of neurogranin and the CaMKII-autophagy pathway were examined using inhibitors. ADEs, rich in neurogranin, alleviated RIR-induced microvascular damage and suppressed OGD/R-triggered pro-inflammatory microglial activation. This was associated with increased neurogranin, CaMKII phosphorylation, and autophagy in microglia. Consequently, ADEs counteracted the harmful effects of activated microglia on RMEC proliferation, migration, and tube formation. Inhibiting CaMKII or autophagy blocked ADEs' protective benefits without altering neurogranin, placing the CaMKII-autophagy axis downstream. ADEs protect RMECs from RIR injury by modulating microglial responses via a neurogranin-CaMKII-autophagy mechanism, revealing their therapeutic potential for retinal microvascular protection.",

Sedanolide (SD) is a compound derived from Chinese medicinal herbs and has structural features associated with anti\u2011inflammatory activity. However, its effect on depressive disorders remains unclear. The present study aimed to examine the therapeutic effects of SD in lipopolysaccharide (LPS)\u2011induced depressive disorder and to investigate the underlying mechanisms. An LPS\u2011induced male mouse model of depressive\u2011like behavior was used to evaluate the therapeutic effect and underlying mechanisms of SD. The mRNA levels of pro\u2011inflammatory cytokines and the activation state of microglia in the medial prefrontal cortex (mPFC) were assessed. In addition, high\u2011throughput RNA sequencing was performed as an unbiased transcriptomic screen to identify differentially expressed genes. Western blotting and ELISA assays were then used to validate the expression and activation levels of key candidate molecules within the identified pathways. BV\u20112 cell line was utilized to assess the aerobic glycolysis in vitro by metabolic extracellular flux analysis. Finally, the selective C3aR antagonist SB290157 was administered to determine whether the effects of SD depended on the downstream C3a/C3aR signaling cascade. SD treatment significantly increased the sucrose preference and reduced immobility time in both the tail suspension test and the forced swimming test in LPS\u2011treated mice. Mechanistically, SD attenuated LPS\u2011induced neuroinflammation and microglial activation in the mPFC. High\u2011throughput RNA sequencing identified C3 and matrix metalloproteinase\u20119 as key transcriptional targets potentially involved in the effects of SD. Crucially, both in vitro and in vivo ELISA assays revealed that SD directly suppressed complement C3 activation by inhibiting its proteolytic cleavage into the active C3a fragments. Furthermore, SD reduced abnormal microglial aerobic glycolysis and restored mitochondrial respiration in vitro. By contrast, pharmacological inhibition of C3aR completely abolished protective effects of SD on behavioral despair, anhedonia, neuroinflammation and metabolic reprogramming. These findings indicate that SD alleviates depressive\u2011like behaviors. The C3a/C3aR signaling axis appears to play a critical role in mediating its anti\u2011inflammatory and anti\u2011glycolytic effects.",

We synthesize evidence showing that titanium dioxide, silver, and zinc oxide nanoparticles differentially alter microbial composition. These microbial shifts intersect with established gut-brain mechanisms, including short-chain fatty acid production and immune modulation, providing plausible pathways linking nanomaterial exposure to neurological outcomes. We propose the 'nanomaterial-microbiome-brain interface' as a novel conceptual framework with twofold relevance-serving both as a potential contributor to Parkinson's disease pathogenesis through unintentional environmental exposure, and as an underexplored avenue for therapeutic intervention. Critical knowledge gaps persist. Addressing these gaps will require integrated approaches that bridge nanomaterial research, microbiome science, and neurodegeneration studies.",

Resveratrol, a polyphenolic phytoalexin mainly found in grapes and red wine, is a promising treatment candidate due to its diverse biological effects and neuroprotective properties. This review demonstrates the regulatory effects of resveratrol on cellular signaling pathways linked to NDs and its neuroprotective mechanisms. Resveratrol enhances neuronal survival, boosts mitochondrial biogenesis, and mitigates oxidative stress by affecting key molecular pathways, including SIRT1/AMPK, PI3K/Akt, MAPK, and Nrf2/ARE. The PI3K/Akt and ERK1/2 pathways promote neuronal regeneration by modulating pro-apoptotic and anti-apoptotic factors. Resveratrol inhibits NF-\u03baB, reducing cytokine release and microglial activation, thereby exhibiting anti-inflammatory properties. It improves cognitive function, synaptic plasticity, and neuronal survival. Despite an increasing pharmacological profile, its practical applicability is limited by inadequate bioavailability, rapid metabolism, and restricted brain penetration. This review demonstrates resveratrol's effect on interconnected signaling networks related to neurodegeneration. We critically compare evidence from preclinical and clinical studies, demonstrating both therapeutic potential and translational limitations. Emerging nanotechnology-based delivery strategies are demonstrated to overcome bioavailability and blood-brain barrier penetration challenges. These insights provide a translational perspective for the future development of resveratrol-based interventions in NDs.",

Emerging evidence identifies the phosphoinositide-3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/Akt/mTOR) and Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathways as interconnected regulators of neuroinflammation and immune dysregulation in MS. This review critically examines the mechanistic crosstalk between these signaling networks and their contribution to disease progression. Dysregulated PI3K/Akt/mTOR signaling influences T-cell activation, immunometabolic reprogramming, autophagy, and oligodendrocyte survival, whereas aberrant activation of the JAK2/STAT3 axis promotes Th17-cell differentiation, cytokine amplification, and sustained inflammatory responses within the central nervous system. Importantly, convergence between Th17/STAT3 signaling and PI3K/Akt-mediated metabolic pathways establishes a regulatory network that enhances microglial activation, blood-brain barrier disruption, and neuronal injury. The review further highlights the context-dependent role of mTOR signaling, which may simultaneously support remyelination and oligodendrocyte maturation while contributing to neurodegeneration when excessively activated. In addition to immune-cell-mediated mechanisms, emerging evidence demonstrates critical contributions of neuronal, glial, endothelial, and oligodendrocyte precursor cell signaling to MS pathology. Preclinical and clinical findings indicate that pharmacological modulation of these pathways can attenuate inflammatory responses and improve neuroprotection; however, therapeutic translation remains challenging because of their dual physiological and pathological functions. Collectively, this review provides an integrated perspective on PI3K/Akt/mTOR-JAK/STAT signaling interactions and highlights cell-specific molecular targets that may facilitate the development of more precise therapeutic strategies for MS.",

The mechanisms driving persistent neuropathology remain incompletely defined, and current therapeutic options are largely nonspecific and patient-dependent. This review analyses emerging evidence on HIV-associated neuropathology in ART-suppressed PWH, with a particular focus on the role of the gut-brain axis. Recent studies demonstrate that the CNS is a stable and transcriptionally active tissue reservoir, which may sustain chronic microglial activation, pro-inflammatory signalling, and synaptic injury. In parallel, accumulating evidence implicates systemic inflammation and gut barrier dysfunction as key contributors to neuroinflammation, linking microbial translocation and gut-brain axis perturbations to cognitive decline in PWH. Furthermore, persistent gut inflammation may result in enteric nervous system (ENS) dysfunction and aberrant signals that directly results in neuroinflammation and neuropathology. These mechanistic insights have driven evaluation of adjunctive strategies targeting HIV transcription and inflammatory pathways as potential approaches to limit neuropathogenesis. Neuropathology in ART-suppressed PWH arises from convergent processes involving CNS HIV reservoirs, myeloid-driven neuroinflammation, systemic immune activation and gut-derived injury, rather than residual brain infection alone. Defining the relative contribution of these pathways in PWH and developing CNS-penetrant interventions that silence viral transcription, restore gut integrity and dampen systemic inflammation, will be critical to preventing and treating HIV-associated neuropathology.",

Increasing evidence suggests that neuroinflammatory cascades orchestrated by microglial activation, astrocytic malfunction, cytokine hyperproduction, and inflammasome signalling are at the core of AD pathogenesis. Conventional anti-amyloid and cholinergic treatments are only symptomatic and neglect the inherent neuroimmune dysregulation. Nanomedicine is a revolutionary frontier in inflammopharmacology, which enables the accurate modulation of neuroinflammatory circuits and enhanced brain delivery of medicines. Nanocarriers designed by engineering, including liposomes, polymeric nanoparticles, dendrimers, and exosomes, allow for targeted delivery across the BBB, increase drug bioavailability, and provide controlled release. The nano-systems are capable of inhibiting pro-inflammatory signalling, such as NF-\u03baB and MAPK pathways, reducing oxidative stress, and enhancing microglial M2 polarization and thus restoring neuronal homeostasis. Recent developments in surface-functionalized and stimuli-responsive nanoplatforms further enable active targeting through receptor-mediated pathways and theranostic imaging in real-time. Comparative studies show that interventions based on nanocarrier-based therapies enhance therapeutic efficacy and safety profiles in preclinical AD models. Future directions include integrating AI-driven nano-design, gene and siRNA delivery, and precision neuropharmacology to enable personalized anti-inflammatory therapies. Substantial progress, translational challenges remain regarding long-term biocompatibility, large-scale production, and clinical validation.

Interleukin-1 receptor-associated kinase M (IRAK-M), which is predominantly expressed in microglia in the central nervous system (CNS), is an endogenous negative regulator of innate immune signaling. Previous studies have linked IRAK-M to the restraint of Toll-like receptor 4 (TLR4) signaling and NLR family pyrin domain-containing 3 (NLRP3) inflammasome-related responses. However, the role of IRAK-M in CM-related pathophysiology and associated neuropsychiatric comorbidities remains unclear. This study aimed to investigate the function of IRAK-M and its underlying molecular mechanisms in a mouse model of chronic migraine. Mice were repeatedly given intraperitoneal injections of nitroglycerin (NTG; 10\u00a0mg/kg) to create a chronic migraine model. Mechanical and thermal sensitivity were assessed using von Frey filaments and the hot-plate test, respectively; light aversion and anxiety-like behaviors were evaluated using the light-aversion test, open-field test, and elevated plus-maze test. To further clarify the role of IRAK-M, both transgenic genetic engineering approaches and adeno-associated virus (AAV)-mediated expression strategies were employed. The underlying molecular mechanisms were further investigated using quantitative PCR, immunoblotting, immunofluorescence, and three-dimensional reconstruction. Repeated administration of NTG increased IRAK-M protein in the trigeminal nucleus caudalis (TNC). IRAK-M deficiency exacerbated mechanical and thermal hyperalgesia, increased c-Fos and CGRP expression, and enhanced microglial activation; these changes were accompanied by increased TLR4/NF-\u03baB-related signaling, NLRP3 inflammasome activation, and GSDMD cleavage. Conversely, TNC-targeted IRAK-M overexpression attenuated pain hypersensitivity and anxiety-like behavioral alterations and was accompanied by corresponding reductions in neuroinflammatory molecular and cellular readouts. These findings support IRAK-M as an important regulator of central sensitization and neuroinflammatory responses in a chronic migraine model. Our findings identify IRAK-M as an important preclinical regulator of microglial reactivity and neuroinflammatory responses in the NTG-induced chronic migraine model. IRAK-M manipulation was accompanied by bidirectional changes in TLR4/NF-\u03baB- and NLRP3/GSDMD-related signaling, pain hypersensitivity, and anxiety-like behavioral alterations. These findings provide a preclinical rationale for further investigation of IRAK-M-related neuroimmune signaling in migraine. Not applicable.",

Here, we delineate a hierarchical epigenetic cascade that promotes transcriptional activation of P2X4R in spinal microglia following nerve injury. In a mouse spared nerve injury (SNI) model, microglial activation was accompanied by increased expression of P2X4R and the histone acetyltransferase p300, together with enhanced histone acetylation (H3K9ac, H3K27ac, H4K5ac, and H4K8ac) and increased chromatin accessibility at the P2rx4 promoter. Microglia-specific deletion of p300 blunted injury-induced histone acetylation and suppressed P2X4R upregulation. We further demonstrate that the acetylation reader BRD4 is recruited to these regions and cooperates with the transcription factor SP1 to drive P2rx4 transcription, supported by chromatin analyses revealing inducible assembly of a BRD4-p300-SP1 axis. Disruption of this cascade via p300 inhibition (C646) or BRD4 blockade (JQ1) attenuated spinal neuroinflammation and alleviated nociceptive hypersensitivity. Notably, reactivation of P2X4R by BzATP largely reversed the analgesic effects of BRD4 inhibition, establishing P2X4R as a critical downstream effector.

Common alterations include reduced beneficial microbial taxa, impaired short-chain fatty acid production, intestinal and blood-brain barrier dysfunction, and sustained inflammatory responses. These findings support the development of microbiota-targeted dietary interventions. This review summarizes current evidence on polyphenols, bioactive peptides, and pectin-derived oligosaccharides (POS) as prebiotic or prebiotic-like compounds with potential activity through the microbiota-gut-brain axis. Particular attention is given to structure-function relationships, host-microbe interactions, and the sustainable recovery of these compounds from food by-products. Preclinical studies suggest that these bioactives may reduce microglial activation, improve mitochondrial function, strengthen intestinal and blood-brain barrier integrity, and enhance cognitive or motor performance. Early clinical studies also indicate possible benefits on mood, selected cognitive outcomes, metabolic regulation, and inflammatory biomarkers, although evidence remains limited. Microbiota-derived metabolites from polyphenols, such as urolithins, together with glycomacropeptide and POS, appear to be key mediators.

In traditional medical practices, it is also commonly prescribed for conditions associated with cognitive decline and age-related disorders. These ethnopharmacological uses are closely linked to neurodegenerative disorders, in which neuroinflammation plays a central role. Ginkgo biloba has shown anti-inflammatory and neuroprotective properties, yet its underlying mechanisms in modulating neuroinflammation are still not fully understood. Neuroinflammation is critically involved in cognitive impairment and neurodegenerative diseases, while therapeutic options remain limited. Ginkgo biloba extract 50 (GBE50) is a standardized formulation with potential neuroprotective properties. This study aimed to assess its effects on neuroinflammation-associated cognitive dysfunction and to clarify the mechanisms involved. Presenilin 1/2 conditional double knockout mice served as a cognitive impairment model, with behavioral tests used to evaluate cognitive function. The constituents of GBE50 were identified by UPLC-Q-TOF-MS, and ATP content was quantified using biochemical assays. The expression of P2X7 receptor, NLRP3 inflammasome-related proteins, inflammatory cytokines, and synaptic markers was determined at both mRNA and protein levels using qRT-PCR and Western blotting. Microglial activation and P2X7R distribution were assessed via immunofluorescence, and hippocampal synaptic plasticity was examined using electrophysiological recordings. Using UPLC-Q-TOF-MS, 51 compounds were characterized in GBE50, mainly flavonoids and terpene lactones, which are likely responsible for its biological activities. Treatment with GBE50 markedly alleviated cognitive impairment in PS cDKO mice. It downregulated P2X7R and key components of the NLRP3 inflammasome (NLRP3, NEK7, Caspase-1, and ASC), while also reducing the transcription of pro-inflammatory cytokines including Il-1\u03b2, Il-18, and Tnf-\u03b1. In parallel, GBE50 restored synaptic protein levels and improved long-term potentiation deficits. Collectively, our findings suggest that modulation of the ATP-P2X7R-NLRP3 axis contributes to the neuroprotective effects of GBE50 in AD, highlighting this pathway as a promising therapeutic target for preventing AD-related neurodegeneration.",

This study aimed to investigate the antidepressant mechanism of SECO and clarify its core target and signaling pathway. Network pharmacology, molecular docking and corticosterone (CORT)-induced depressive mice model were applied. Behavioral tests, histological staining, ELISA and Western blot were performed for evaluation. Behavioral tests confirmed that SECO significantly improved depressive-like behaviors, increased sucrose preference and exploratory ability, and reduced immobility time. SECO ameliorated hippocampal CA1 neuronal morphological damage and neuronal loss. Treatment with SECO significantly decreased serum corticosterone (CORT) concentrations and hippocampal prostaglandin E2 (PGE2) levels. Concurrently, it elevated serum levels of key neurotransmitters, namely serotonin (5-HT), norepinephrine (NE), and dopamine (DA), and increased cyclic adenosine monophosphate (cAMP) content in the hippocampus. Mechanistically, SECO downregulated the expression of prostaglandin-endoperoxide synthase 2 (PTGS2) and activated the cAMP-PKA-CREB-BDNF signaling cascade. SECO alleviates neuroinflammation via PTGS2 inhibition and enhances neuronal plasticity by activating the cAMP/PKA-CREB-BDNF signaling pathway. These two synergistic effects contribute to the neuroprotective action of SECO, thereby ameliorating CORT-induced depressive-like behaviors in mice.",

Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.",

These effects mimic key features of neurodegenerative diseases and share mechanistic overlap with adverse outcomes of airborne environmental exposures that compromise oxygen homeostasis through mechanisms involving Hypoxia-Inducible Factor 1-alpha (HIF-1\u03b1) stabilization, proteasome dysfunction, and gut-brain axis disruption. In this study, C57BL/6 mice were exposed to 12% O2 for 2\u00a0months and received oral probiotics supplementation, which rescued short-term memory deficits in the novel object recognition test, reduced hippocampal HIF-1\u03b1 accumulation, restored prolyl hydroxylase domain protein 2 (PHD2) and ubiquitin-proteasome pathway, and attenuated neuroinflammation and apoptosis, while elevating brain-derived neurotrophic factor (BDNF). Probiotics also normalized plasma gut hormones (glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and leptin), enhanced ileal tight junction proteins (zonulin-1, occludin and claudin) in Ileal tissue, countered gut microbiota \u03b2-diversity shifts and restored beneficial bacterial metabolites with improved predicted metabolic pathways. These findings provide preclinical evidence that probiotics oral supplementation can restore gut-brain axis homeostasis, and mitigate chronic hypoxia related neuroinflammation, offering a potential therapeutic strategy against neurodegeneration triggered by oxygen\u2011depriving environmental and pathological conditions.",

In vascular dementia (VaD)-the second most common dementia-cerebrovascular pathology drives distinct microglial activation states. This review synthesizes current understanding of microglial phenotypes in neurological disease, focusing on their contributions to VaD following vascular insults such as chronic cerebral hypoperfusion and stroke. Key VaD-associated phenotypes are described, including spatially segregated subsets in ischemic territories (ICAM and IPAM microglia), TREM1 + -activated microglia in hemorrhagic foci, and cytokine-responsive microglia (CRM) identified in human VaD brain. The molecular drivers of this heterogeneity are discussed, arguing for moving beyond the reductive M1/M2 dichotomy. The broader significance lies in a proposed framework for microglia-targeted therapeutic strategies, encompassing precision immunomodulation, antibody-mediated approaches, and in situ cellular reprogramming as promising avenues for future intervention.",

The crosstalk between the heart and hypothalamic microglia in HFpEF, particularly the role of small extracellular vesicles (sEVs), remains insufficiently explored. We constructed an HFpEF model in mice by combining a long-term high-fat diet with the nitric oxide synthase inhibitor l-NAME (N[\u03c9]-nitro-l-arginine methyl ester). These mice exhibited microglial activation and hypothalamic inflammation. Microglial depletion with PLX3397 suppressed sympathetic activity and improved cardiac dysfunction in HFpEF. sEVs derived from the myocardium of HFpEF mice induced a proinflammatory M1 phenotype in microglia, leading to hypothalamic inflammation and sympathetic activation. Intraperitoneal injection of the sEV biogenesis inhibitor GW4869 reversed these changes in HFpEF mice. Similar pathological changes were observed in BV2 microglia treated with sEVs isolated from palmitic acid-treated HL-1 cardiomyocytes. Bioinformatic and RT-qPCR analyses revealed a notable upregulation of miR-200c-3p in sEVs derived from both HFpEF myocardial tissue and palmitic acid-treated HL-1 cardiomyocytes, as well as in microglia. A cardiomyocyte-specific miR-200c-3p sponge inhibited microglial activation, hypothalamic inflammation, and sympathetic activation in HFpEF mice. Conversely, a miR-200c-3p mimic exacerbated proinflammatory responses in BV2 cells, while a miR-200c-3p inhibitor prevented the transition to a proinflammatory phenotype. The antiinflammatory protein DUSP1 (dual-specificity phosphatase 1) was validated as a potential downstream target of miR-200c-3p in microglia. Our study reveals that HFpEF prompts cardiomyocytes to release sEVs enriched with miR-200c-3p, leading to hypothalamic inflammation and evoking sympathetic outflow, which in turn exacerbates cardiac dysfunction. Focusing on sEV-mediated communication between cardiomyocytes and microglia may offer a new therapeutic approach for HFpEF.",

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.",

The CX3CL1/CX3CR1 signaling is closely related to mood disorders, and this study aims to investigate its role in ketamine's antidepressant actions. We pharmacologically (AZD8797, a selective CX3CR1 antagonist) and genetically (intra-mPFC microinjection with AAV-CX3CR1-siRNA) manipulated the CX3CL1/CX3CR1 signaling and investigated their effects on ketamine's antidepressant-like effects in mice treated with corticosterone (Cort), and observed changes in synaptic plasticity in response to these manipulations. We found that 24\u2009h after drug injection, ketamine (10\u2009mg/kg, i.p.) significantly reversed the Cort-induced depression-like behaviors, and inhibited the overexpression of pro-inflammatory cytokines and microglial activation. Ketamine significantly improved the Cort-induced impairment in the dendritic complexity and spine densities. In addition, our ELISA results showed that ketamine significantly inhibited the activation of CX3CL1/CX3CR1 signaling, and ketamine attenuated the upregulation of CX3CR1 and CX3CL1 expression in Cort-treated HT22 and BV2 cells in vitro. Furthermore, pretreatment with AZD8797 (0.8\u2009mg/kg, i.p., twice a week) completely blocked ketamine's antidepressant-like behavioral effects and eliminated ketamine-induced enhancement in the synaptic plasticity; intra-mPFC microinjection with AAV-CX3CR1-siRNA also prevented ketamine's behavioral effects and beneficial effects on the synaptic plasticity. These findings demonstrated that CX3CL1/CX3CR1 signaling-mediated synaptic plasticity played essential roles in ketamine's antidepressant-like effects, which opened a new door to targeting chemokines to improve depression symptoms.",

Here, we developed an injectable catechol-functionalized carboxymethyl cellulose hydrogel, CMCDA, as a bioadhesive and antioxidative intravitreal platform. Through dopamine grafting and oxidative crosslinking, CMCDA exhibited shear-thinning injectability, self-healing behavior, wet-tissue adhesion, controlled biodegradability, and good biocompatibility. In an optic nerve crush model, CMCDA significantly reduced retinal reactive oxygen species (ROS) accumulation, preserved retinal ganglion cells, promoted axonal regeneration, and attenuated microglial activation, with 7 wt% CMCDA showing the strongest therapeutic efficacy. Single-cell RNA sequencing further suggested that CMCDA reshaped the injured retinal microenvironment by suppressing apoptotic, oxidative-stress, and inflammatory pathways while supporting phototransduction-related programs. Importantly, these structural and molecular benefits were accompanied by improved visual function, as confirmed by visual cliff testing and electroretinography. Overall, CMCDA represents a multifunctional cellulose-based hydrogel platform for minimally invasive antioxidative neuroprotection, axonal repair, and functional recovery after optic nerve injury.",

Given microglial activation drives autoimmune uveitis, we investigated whether VISTA protects against experimental autoimmune uveitis (EAU) by modulating retinal microglia. VISTA expression was analyzed by flow cytometry in active VKH patients and healthy controls. Functional studies in LPS/IFN-\u03b3-stimulated BV2 microglia used genetic knockdown/overexpression and modulating antibodies (13F3, MH5A). Activation status, cytokine secretion, migration, and TLR4/MyD88/NF-\u03baB signaling were assessed. An EAU mouse model received intravitreal adeno-associated virus-mediated VISTA overexpression, with severity evaluated clinically and histopathologically. VISTA was downregulated in circulating immune cells of VKH patients and in retinal microglia during EAU. In vitro, inflammatory stimuli reduced microglial VISTA. Its knockdown or blockade exacerbated microglial activation, pro-inflammatory mediator secretion (TNF-\u03b1, iNOS, COX2), and migration, while overexpression or agonism suppressed activation. Critically, intravitreal VISTA overexpression alleviated EAU severity. Mechanistically, VISTA deficiency potentiated activation by enhancing TLR4/MyD88/NF-\u03baB signaling. VISTA is a crucial gatekeeper of ocular immune homeostasis. Its downregulation promotes uveitis via microglial TLR4/MyD88/NF-\u03baB pathway activation, making VISTA signaling restoration a promising therapeutic strategy.",

Here, male C57BL/6J mice were orally exposed to F-53B (6:2Cl-PFESA; 0.1 or 1\u00a0mg/kg/day) during juvenility for four weeks. F-53B selectively impaired recognition memory and social novelty preference, whereas locomotor activity, anxiety-like behavior, and Y-maze working memory were largely preserved. Mechanistically, F-53B compromised intestinal barrier integrity, as evidenced by reduced occludin expression and disrupted ZO-1 continuity, accompanied by elevated circulating lipopolysaccharide (LPS) and a systemic pro-inflammatory cytokine shift. In parallel, the hippocampus exhibited microglial activation, enhanced inflammatory signaling, and reduced PSD95 expression, consistent with neuroinflammatory stress and synaptic vulnerability. Shotgun metagenomics revealed pronounced microbiome restructuring and network rewiring, while widely targeted metabolomics converged on a marked disruption of tryptophan metabolism, characterized by depletion of microbiota-derived indole metabolites, including indole-3-propionic acid (IPA), together with altered serotonin-related signatures. Notably, oral IPA supplementation rescued behavioral deficits and attenuated gut-brain inflammatory alterations, restoring intestinal aryl hydrocarbon receptor (AhR) nuclear translocation, reducing LPS and cytokine levels, and ameliorating hippocampal inflammatory phenotypes. Collectively, these findings provide mechanistic evidence that a microbiota-tryptophan metabolite-gut barrier-inflammation axis links exposure to substitute PFAS with selective neurobehavioral dysfunction, highlighting microbiota-derived metabolites as potential modulators of PFAS-associated neurotoxicity.",

Here, we investigate a diverse panel of 12 immunomodulatory drugs as host-directed treatments (HDTs) for TB meningitis utilizing a cross-species framework comprising studies in a mouse model of TB meningitis with clinical endpoints, and parallel mechanistic studies in a newly developed immune-vascularized human brain organoid model of TB meningitis and peripheral blood mononuclear cells (PBMCs) from patients with TB meningitis. Imatinib, bestatin, roflumilast, palacaparib, thalidomide/pomalidomide and semaglutide outperform the current standard of care by reducing mortality and/or neurological deficits in mice via suppression of neuroinflammation. Importantly, these HDTs significantly reduce microglial activation in Mycobacterium tuberculosis-infected human brain organoids and attenuate proinflammatory cytokines, particularly IFN\u03b3 within CD4+\u2009T-cells in patient-derived PBMCs.

Randomized clinical trials and real-world data demonstrate that modern disease-modifying therapies substantially reduce relapse rates and acute inflammatory activity detected by magnetic resonance imaging (MRI). However, disability accumulation increasingly occurs independent of relapse activity, highlighting progression biology as the principal unmet need. Converging epidemiological and molecular evidence supports a pivotal role for Epstein-Barr virus (EBV) infection in disease initiation, whereas later stages appear dominated by brain-intrinsic mechanisms, including compartmentalized inflammation, microglial activation, failure of remyelination and accelerated biological ageing. Population-based cohorts demonstrate that early high-efficacy therapy improves long-term outcomes, yet the risk of progression rises markedly after midlife despite effective relapse suppression. Emerging biomarkers, such as serum neurofilament light chain, glial fibrillary acidic protein, paramagnetic rim lesions and advanced quantitative MRI metrics, now enable more granular monitoring of progressive pathology. Integration of imaging, fluid biomarkers, genetics and machine learning offers opportunities for individualized benefit-risk stratification. Brain-penetrant Bruton's tyrosine kinase inhibitors, CD40 ligand-targeting biologics, refined B-cell-depleting strategies and emerging chimeric antigen receptor T-cell therapies represent promising approaches to target different aspects of compartmentalized inflammation and smoldering disease biology. Future management will require mechanism-informed treatment algorithms that align therapeutic choice with dominant disease drivers while incorporating comorbidity management, de-escalation strategies and potential EBV-targeted preventive approaches to optimize outcomes across the entire disease course.",

Here, we address this limitation by combining proximity ligation assay (PLA) with the newly applied MolBoolean methodology, enabling in\u00a0situ quantification of the partitioning of adenosine A2A and cannabinoid CB2 receptor-associated signals between non-interacting fractions and A2A-CB2 heteromeric complexes in primary microglia. We show that resting microglia contain detectable A2A-CB2 heteromers together with a substantial non-interacting A2A-associated signal fraction. Selective activation of either receptor promotes redistribution of the detectable receptor-associated signal toward the heteromer-associated fraction. Ligand-induced redistribution also occurred in HEK-293T cells expressing the two receptors. In contrast, pro-inflammatory activation of primary microglia with LPS/IFN-\u03b3 markedly changes the basal organization of the receptor system, increasing the proportion of MolBoolean-detectable signal associated with A2A-CB2 complexes, with approximately 70% of the detectable receptor-associated signal corresponding to heteromeric complexes. In this inflammatory context, further agonist-induced repartitioning is strongly limited compared with that observed in resting microglia. These findings identify inflammation-dependent receptor partitioning as a quantitatively measurable feature of microglial A2A and CB2 receptor organization and provide a framework for interpreting how receptor context may influence future studies of A2A-CB2 pharmacology under neuroinflammatory conditions.",

A central regulator of these diverse functions is intracellular Ca2+ signaling, which connects extracellular cues to transcriptional and metabolic programs that shape microglial activation states. Recent advances have expanded understanding of the 'Ca2+ toolkit' in microglia, which includes P2X and P2Y receptors, Orai Ca2+ channels, transient receptor potential channels, inositol triphosphate receptors, and organellar Ca2+ handling systems. These pathways generate dynamic and spatially localized Ca2+ signals that regulate numerous effector functions, including process motility, cytokine production, phagocytosis, metabolism, and communication with other brain cells. Emerging evidence further identifies dysregulated Ca2+ signaling as a key driver of chronic neuroinflammation in brain disorders. Here, we review the major components of the microglial Ca2+ signaling toolkit, discuss their molecular mechanisms and physiological functions, and highlight contributions to neuroinflammatory diseases.",

We previously identified hippocampal salt-inducible kinase 2 (SIK2) as an important regulator of depression pathogenesis through modulation of the cAMP response element-binding protein (CREB)-regulated transcription coactivator 1 (CRTC1)-CREB-brain derived neurotrophic factor (BDNF) pathway. The current study investigated the antidepressant-like efficacy of YKL-06-061, a newly developed potent pan-SIK inhibitor, in male C57BL/6J mice. We established two well-validated depression models, chronic social defeat stress and chronic unpredictable mild stress, to examine the efficacy of daily intraperitoneal YKL-06-061 injection against behavioral despair as measured by forced swim and tail suspension tests, anhedonia as measured by sucrose preference, and social withdrawal as measured by the social interaction test. Western blotting, immunofluorescence, and co-immunoprecipitation were then conducted to evaluate the changes in hippocampal SIK2-CRTC1 signaling, BDNF-TrkB signaling, and adult neurogenesis among all groups. To further determine the antidepressant mechanism of YKL-06-061, model mice were re-examined following adeno-associated virus (AAV)-mediated overexpression of hippocampal SIK2 or knockdown of hippocampal CRTC1/CREB/BDNF. YKL-06-061 administration suppressed depression-like behaviors in both models, normalized chronic stress-induced alteration in hippocampal SIK2-CRTC1 signaling, and rescued chronic stress-induced impairments in hippocampal BDNF signaling and adult neurogenesis. Both genetic overexpression of hippocampal SIK2 and knockdown of hippocampal CRTC1/CREB/BDNF expression attenuated the antidepressant-like actions of YKL-06-061 in mice. Our findings further establish hippocampal SIK2-CRTC1-CREB-BDNF signaling as an antidepressant target and support YKL-06-061 as a potential antidepressant candidate.",

Thirty-five university students (mTBI = 9; controls = 26) aged 18-24 years completed phonemic (FAS) and semantic (animal naming) verbal fluency tasks. Total correct responses, mean cluster size and number of switches were analysed. Compared with controls, individuals with mTBI produced fewer 'S' words (z = 2.66, P = 0.007, r = 0.45) and semantic switches (z = 2.45, P = 0.015, r = 0.41). Both groups were significantly different in semantic and phonemic clusters (mTBI: z = 2.22, P = 0.026, r = 0.74; controls: z = 3.51; P < 0.001, r = 0.69). No group differences were observed for phonemic switching. Findings indicate subtle reductions in cognitive flexibility and verbal productivity in individuals with chronic mTBI. Clustering and switching analyses in verbal fluency tasks may detect subtle, executive deficits in individuals with chronic mTBI that are not captured by total word count alone. These findings support the feasibility of subcomponent verbal fluency measures as sensitive tools for long-term mTBI assessment and monitoring.",

Twenty-four adult SD rats were randomized equally into normoxic control group, HH model group, low-dose (100 mg/kg) GAS group (HH+GAS-L group), and high-dose (200 mg/kg) GAS group (HH+GAS-H group). In the latter 3 groups, the rats were exposed to HH in a hypobaric oxygen chamber for 24 h to simulate the condition at an altitude of 6000 m, and GAS was administered intraperitoneally once daily for 7 days. Cerebral cortex tissues were collected for analysis of P53, SLC7A11, and GPX4 protein expressions using Western blotting and for determination of the levels of reactive oxygen species (ROS), malondialdehyde (MDA), glutathione (GSH), and ferrous ion (Fe\u00b2\u207a). In cultured HT22 neurons exposed to oxygen-glucose deprivation (OGD), the effects of GAS (500 \u03bcmol/L), nutlin-3 (a P53 agonist; 10 \u03bcmol/L) or their combination were examined on ferroptosis-related protein expressions, intracellular ROS, lipid peroxidation, MDA, GSH, cell viability, mitochondrial membrane potential, and Fe\u00b2\u207a levels. In the rat models of HH, GAS treatment significantly inhibited P53 expression, upregulated SLC7A11 and GPX4 proteins, markedly reduced Fe\u00b2\u207a, ROS, and MDA levels, and increased GSH content in the cerebral cortex. In cultured HT22 neurons, GAS treatment effectively alleviated OGD-induced cell ferroptosis as shown by decreased P53 expression, increased SLC7A11 and GPX4 expressions, and lowered levels of intracellular ROS generation, lipid peroxidation, and Fe\u00b2\u207a accumulation, along with obvious restoration of GSH levels, cell viability, and mitochondrial membrane potential. The protective effects of GAS was markedly attenuated by activation of the P53 pathway using nutlin-3. GAS produces neuroprotective effects against HH-induced brain injury in rats by inhibiting neuronal ferroptosis via regulating the P53/SLC7A11/GPX4 signaling pathway. \u76ee\u7684: \u7814\u7a76\u5929\u9ebb\u7d20\uff08GAS\uff09\u5bf9\u9ad8\u539f\u4f4e\u538b\u7f3a\u6c27\uff08HH\uff09\u6027\u8111\u635f\u4f24\u7684\u795e\u7ecf\u4fdd\u62a4\u4f5c\u7528\uff0c\u5e76\u63a2\u8ba8\u5176\u673a\u5236\u662f\u5426\u4e0e\u8c03\u8282P53/SLC7A11/GPX4\u4fe1\u53f7\u901a\u8def\u3001\u6291\u5236\u795e\u7ecf\u5143\u94c1\u6b7b\u4ea1\u76f8\u5173\u3002\u65b9\u6cd5: \u4f53\u5185\u5b9e\u9a8c\u9009\u53d624\u53ea\u6210\u5e74SD\u5927\u9f20\uff0c\u968f\u673a\u5206\u4e3a4\u7ec4\uff08n=6\uff09:\u5e38\u538b\u5e38\u6c27\u5bf9\u7167\u7ec4\uff08Nor\uff09\u3001\u4f4e\u538b\u7f3a\u6c27\u6a21\u578b\u7ec4\uff08HH\uff09\u3001\u5929\u9ebb\u7d20\u4f4e\u5242\u91cf\u7ec4\uff08HH+GAS-L\uff0c100 mg/kg\uff09\u3001\u5929\u9ebb\u7d20\u9ad8\u5242\u91cf\u7ec4\uff08HH+GAS-H\uff0c200 mg/kg\uff09\u3002\u9664\u5bf9\u7167\u7ec4\u5916\uff0c\u5176\u4f59\u5404\u7ec4\u5927\u9f20\u7f6e\u4e8e\u6a21\u62df\u6d77\u62d46000 m\u7684\u4f4e\u538b\u6c27\u8231\u4e2d\u6301\u7eed\u66b4\u973224 h\u4ee5\u5efa\u7acbHH\u6a21\u578b\u3002\u5929\u9ebb\u7d20\u4e8e\u9020\u6a21\u540e\u8179\u8154\u7ed9\u836f\uff0c1\u6b21/d\u3002\u53d6\u7b2c7\u5929\u7684\u8111\u76ae\u5c42\u8fdb\u884cWestern blotting\u68c0\u6d4bP53\u3001SLC7A11\u53caGPX4\u86cb\u767d\u8868\u8fbe\uff0c\u540c\u65f6\u6d4b\u5b9a\u7ec4\u7ec7\u5185\u6d3b\u6027\u6c27\u6807\u5fd7\u7269\uff08DHE\uff09\u3001\u4e19\u4e8c\u919b\uff08MDA\uff09\u3001\u8c37\u80f1\u7518\u80bd\uff08GSH\uff09\u53ca\u4e9a\u94c1\u79bb\u5b50\uff08Fe\u00b2\u207a\uff09\u7684\u542b\u91cf\u3002\u4f53\u5916\u57f9\u517bHT22\u795e\u7ecf\u5143\uff0c\u5206\u4e3a:\u5bf9\u7167\u7ec4\uff08Control\uff09\u3001\u6a21\u578b\u7ec4\uff08OGD\uff09\u3001\u5929\u9ebb\u7d20\u5e72\u9884\u7ec4\uff08OGD+GAS\uff0c500 \u03bcmol/L\uff09\u3001P53\u6fc0\u52a8\u5242\u7ec4\uff08OGD+Nutlin-3\uff0c10 \u03bcmol/L\uff09\u53ca\u8054\u5408\u5904\u7406\u7ec4\uff08OGD+GAS+Nutlin-3\uff09\u3002\u68c0\u6d4b\u6307\u6807\u5305\u62ec\u94c1\u6b7b\u4ea1\u76f8\u5173\u86cb\u767d\u8868\u8fbe\u3001\u7ec6\u80de\u5185\u6d3b\u6027\u6c27\uff08DCFH-DA\uff09\u3001\u8102\u8d28\u8fc7\u6c27\u5316\uff08BODIPY-C11\uff09\u3001MDA\u3001GSH\u3001\u7ec6\u80de\u5b58\u6d3b\u7387\uff08CCK-8\uff09\u3001\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\uff08JC-1\uff09\u53ca\u4e9a\u94c1\u79bb\u5b50\uff08FerroOrange\uff09\u3002\u7ed3\u679c: \u52a8\u7269\u5b9e\u9a8c\u663e\u793a\uff0c\u4e0eHH\u7ec4\u76f8\u6bd4\uff0c\u5929\u9ebb\u7d20\u663e\u8457\u6291\u5236P53\u8868\u8fbe\uff0c\u4e0a\u8c03SLC7A11\u4e0eGPX4\u86cb\u767d\u6c34\u5e73\uff08P<0.05\uff09\uff0c\u5e76\u663e\u8457\u964d\u4f4e\u8111\u76ae\u5c42\u7ec4\u7ec7Fe\u00b2\u207a\u3001ROS\u548cMDA\u542b\u91cf\uff0c\u63d0\u9ad8GSH\u6c34\u5e73\uff08P<0.05\uff09\u3002\u7ec6\u80de\u5b9e\u9a8c\u7ed3\u679c\u4e00\u81f4\uff0c\u5929\u9ebb\u7d20\u6709\u6548\u51cf\u8f7b\u4f4e\u538b\u7f3a\u6c27\u8bf1\u5bfc\u7684\u94c1\u6b7b\u4ea1\uff0c\u8868\u73b0\u4e3aP53\u8868\u8fbe\u4e0b\u964d\uff0cSLC7A11\u4e0eGPX4\u8868\u8fbe\u5347\u9ad8\uff08P<0.05\uff09\uff0c\u7ec6\u80de\u5185ROS\u751f\u6210\u3001\u8102\u8d28\u8fc7\u6c27\u5316\u548cFe\u00b2\u207a\u84c4\u79ef\u88ab\u6291\u5236\uff0c\u540c\u65f6GSH\u542b\u91cf\u3001\u7ec6\u80de\u6d3b\u6027\u548c\u7ebf\u7c92\u4f53\u819c\u7535\u4f4d\u663e\u8457\u6062\u590d\uff08P<0.05\uff09\u3002\u800c\u4f7f\u7528Nutlin-3\u6fc0\u6d3bP53\u4fe1\u53f7\u901a\u8def\u540e\uff0c\u5929\u9ebb\u7d20\u7684\u4fdd\u62a4\u4f5c\u7528\u88ab\u660e\u663e\u9006\u8f6c\uff08P<0.05\uff09\u3002\u7ed3\u8bba: \u5929\u9ebb\u7d20\u53ef\u80fd\u901a\u8fc7\u8c03\u63a7P53/SLC7A11/GPX4\u4fe1\u53f7\u901a\u8def\u6291\u5236\u795e\u7ecf\u5143\u94c1\u6b7b\u4ea1\uff0c\u4ece\u800c\u5bf9\u9ad8\u539f\u4f4e\u538b\u7f3a\u6c27\u6027\u8111\u635f\u4f24\u53d1\u6325\u795e\u7ecf\u4fdd\u62a4\u4f5c\u7528\u3002.",

In a Transwell co-culture system of BV-2 and HT22 cells, OGD/R+fibrinogen (FIB) injury was induced in BV-2 cells followed by treatment with TQHXD-CSF intervention, and HT22 cells in the lower chamber were cultured under normal conditions. The cells were observed for changes in cell morphology, viability, intracellular ROS level, apoptosis, M1/M2 polarization, and FIB-containing extracellular vesicles (EVs). The cellular expressions of NLRP3, ASC, caspase-1, GSDMD, IL-1\u03b2, and IL-18 were quantified using Western blotting, and FIB-NLRP3 binding was confirmed by pull-down assay. OGD/R+FIB injury caused polarization of BV-2 cells to the pro-inflammatory M1 phenotype, increased CD86 expression and release of FIB-containing EVs, and activated the NLRP3 inflammasome. The co-cultured HT22 cells showed reduced cell viability, elevated ROS, and increased cells apoptosis. Treatment with TQHXD-CSF promoted M2 polarization in BV-2 cells, upregulated CD206 expression, suppressed FIB+ EVs secretion, and inhibited NLRP3 inflammasome activation in HT22 cells, which showed significantly lowered expressions of NLRP3, ASC, caspase-1, GSDMD, IL-1\u03b2, and IL-18 proteins and hence reduced inflammatory injury and cell apoptosis. Pull-down assay confirmed direct FIB and NLRP3 binding. In the co-culture system of BV-2 cells and HT22 cells, TQHXD-CSF treatment protects HT22 cells against OGD/R+FIB-induced injury by inhibiting FIB-containing EVs release from BV-2 cells and suppressing NLRP3 inflammasome activation. \u76ee\u7684: \u63a2\u8ba8\u901a\u7a8d\u6d3b\u8840\u6c64\u542b\u836f\u8111\u810a\u6db2\uff08TQHXD-CSF\uff09\u5bf9\u6c27\u7cd6\u5265\u593a/\u590d\u7cd6\u590d\u6c27\uff08OGD/R\uff09\u635f\u4f24\u5c0f\u9f20\u5c0f\u80f6\u8d28\u7ec6\u80de\uff08BV-2\uff09\u708e\u75c7\u635f\u4f24\u7684\u4fee\u590d\u4f5c\u7528\uff0c\u4ee5\u53ca\u5176\u5bf9\u5171\u57f9\u517b\u4f53\u7cfb\u4e2d\u795e\u7ecf\u5143\uff08HT22\uff09\u7ec6\u80de\u7684\u4fdd\u62a4\u4f5c\u7528\u3002\u65b9\u6cd5: \u91c7\u7528Transwell\u5171\u57f9\u517b\u4f53\u7cfb\uff0c\u5c06BV-2\u7ec6\u80de\u4e0eHT22\u7ec6\u80de\u8fdb\u884c\u5171\u57f9\u517b;\u5bf9Transwell\u5c0f\u5ba4\u4e2dBV-2\u7ec6\u80de\u5efa\u7acbOGD/R+FIB\u635f\u4f24\u6a21\u578b\u540e\uff0c\u7ed9\u4e88TQHXD-CSF\u5e72\u9884\uff0c\u4e0b\u5c42HT22\u7ec6\u80de\u6b63\u5e38\u57f9\u517b\u3002\u901a\u8fc7\u5012\u7f6e\u663e\u5fae\u955c\u89c2\u5bdf\u5404\u7ec4BV-2\u7ec6\u80de\u5f62\u6001\u53d8\u5316;\u91c7\u7528CCK-8\u6cd5\u68c0\u6d4b\u5404\u7ec4\u7ec6\u80de\u5b58\u6d3b\u7387;\u6d41\u5f0f\u7ec6\u80de\u672f\u5206\u6790\u7ec6\u80de\u5185\u6d3b\u6027\u6c27\uff08ROS\uff09\u542b\u91cf\u53ca\u7ec6\u80de\u51cb\u4ea1\u7387;CD86/CD206\u514d\u75ab\u8367\u5149\u53cc\u67d3\u6cd5\u89c2\u5bdfBV-2\u7ec6\u80de\u6781\u5316\u8868\u578b;\u900f\u5c04\u7535\u955c\u7ed3\u5408\u6d41\u5f0f\u7ec6\u80de\u672f\u9274\u5b9a\u5e76\u5b9a\u91cf\u542b\u7ea4\u7ef4\u86cb\u767d\u539f\uff08FIB\uff09\u7684\u7ec6\u80de\u5916\u56ca\u6ce1\uff08EVs\uff09;Western blotting\u6cd5\u68c0\u6d4bNLRP3\u708e\u6027\u4f53\u76f8\u5173\u86cb\u767d\uff08NLRP3\u3001ASC\u3001Caspase-1\u3001GSDMD\uff09\u53ca\u708e\u75c7\u56e0\u5b50\uff08IL-1\u03b2\u3001IL-18\uff09\u7684\u8868\u8fbe\u6c34\u5e73;Pull-down\u5b9e\u9a8c\u9a8c\u8bc1FIB\u4e0eNLRP3\u86cb\u767d\u7684\u76f8\u4e92\u4f5c\u7528\u3002\u7ed3\u679c: OGD/R+FIB\u635f\u4f24\u53ef\u663e\u8457\u8bf1\u5bfcBV-2\u7ec6\u80de\u5411M1\u578b\u4fc3\u708e\u8868\u578b\u6781\u5316\uff0c\u4e0a\u8c03CD86\u8868\u8fbe\u6c34\u5e73\uff0c\u589e\u52a0\u542bFIB\u7684EVs\u91ca\u653e\uff0c\u6fc0\u6d3bNLRP3\u708e\u6027\u4f53\u901a\u8def\uff08P<0.01\uff09;\u8fdb\u800c\u5bfc\u81f4\u5171\u57f9\u517b\u7684HT22\u7ec6\u80de\u6d3b\u529b\u4e0b\u964d\u3001ROS\u751f\u6210\u589e\u591a\u3001\u51cb\u4ea1\u7387\u5347\u9ad8\uff08P<0.01\uff09\u3002TQHXD-CSF\u5e72\u9884\u540e\uff0c\u53ef\u663e\u8457\u4fc3\u8fdbBV-2\u7ec6\u80de\u5411M2\u578b\u6297\u708e\u8868\u578b\u6781\u5316\uff0c\u4e0a\u8c03\u6297\u708e\u6807\u5fd7\u7269CD206\u8868\u8fbe\uff0c\u51cf\u5c11\u542bFIB\u7684EVs\u5206\u6ccc\uff08P<0.01\uff09;\u540c\u65f6\u53ef\u663e\u8457\u6291\u5236BV-2\u7ec6\u80de\u6d3b\u5316\u4ecb\u5bfc\u7684HT22\u7ec6\u80de\u4e2dNLRP3\u3001ASC\u3001Caspase-1\u3001GSDMD\u3001IL-1\u03b2\u3001IL-18\u7684\u86cb\u767d\u8868\u8fbe\uff0c\u6291\u5236NLRP3\u708e\u6027\u4f53\u8fc7\u5ea6\u6fc0\u6d3b\uff0c\u660e\u663e\u6539\u5584HT22\u7ec6\u80de\u7684\u708e\u75c7\u635f\u4f24\u53ca\u51cb\u4ea1\u60c5\u51b5\uff08P<0.01\uff09\u3002Pull-down\u5b9e\u9a8c\u8bc1\u5b9e\uff0cFIB\u4e0eNLRP3\u86cb\u767d\u4e4b\u95f4\u5b58\u5728\u76f4\u63a5\u76f8\u4e92\u4f5c\u7528\u3002\u7ed3\u8bba: TQHXD-CSF\u53ef\u901a\u8fc7\u6291\u5236OGD/R+FIB\u635f\u4f24\u540eBV-2\u7ec6\u80de\u91ca\u653e\u542bFIB\u7684EVs\uff0c\u963b\u65adNLRP3\u708e\u6027\u4f53\u6fc0\u6d3b\u4ecb\u5bfc\u7684\u708e\u75c7\u53cd\u5e94\uff0c\u5bf9HT22\u7ec6\u80de\u53d1\u6325\u4fdd\u62a4\u4f5c\u7528\uff0c\u4e3a\u51cf\u8f7b\u7f3a\u8840\u6027\u8111\u5352\u4e2d\u540e\u7684\u795e\u7ecf\u708e\u75c7\u635f\u4f24\u63d0\u4f9b\u5b9e\u9a8c\u4f9d\u636e\u3002.",
"42487016": "ID: 42487016\nTitle: Hypoxia as an amplifier of synovial inflammation in rheumatoid arthritis.\nAbstract: Inflammatory arthritis is characterized by neovascularization, leukocyte extravasation and synovial hyperplasia, leading to joint destruction and functional disability. Although increased synovial angiogenesis is a hallmark of synovial inflammation, efficiency of the oxygen supply to the synovium is poor, leading to a hypoxic gradient that impacts differential cellular responses. This hypoxic gradient occurs as infiltrating cells and cells that reside within the joint increase their metabolic demand beyond what the highly dysregulated vasculature can supply. This hypoxic environment favours an increase in reactive oxygen species, leading to oxidative damage that further promotes inflammation. In this adverse microenvironment, synovial cells adapt to generate energy and switch their cellular metabolism from a resting regulatory state to a highly metabolically active state, enabling them to produce essential building blocks to support their proliferation. This metabolic shift results in the accumulation of metabolic intermediates that function as signalling molecules, which further dictate the inflammatory response. However, the synovium is a complex multicellular tissue, and the specific cellular reliance on oxygen and metabolites differs across the synovium. Cellular demands depend on anatomical location, cell-cell interactions and competition for nutrients. Understanding the complex interplay between hypoxia-induced signalling pathways, oxidative stress and inflammatory responses will provide a better insight into the underlying mechanisms of disease pathogenesis.",

The Glasgow Coma Scale-Pupils (GCS-P) score integrates the GCS with pupillary reactivity to improve the prediction of intracranial injury severity. This study aims to examine the correlation between GCS-P scores at presentation and brain CT findings in patients with head trauma, particularly in a semi-urban Indian emergency setting where CT access is often delayed, to validate GCS-P as a practical triage tool in the resource-limited environments. This retrospective study enrolled 300 adult patients with acute head injuries presenting over 3 months. Patients underwent standardized neurological evaluation including GCS and pupillary assessments followed by noncontrast CT imaging within 2 h. The GCS-P score was computed by subtracting the pupil reactivity score from total GCS. CT findings were categorized by injury severity (normal, mild, moderate, and severe). Spearman's rank correlation analysis assessed the relationship between GCS-P scores and CT severity. The mean age was 37.6 \u00b1 15.8 years; 79.3% were male, and road traffic accidents were the predominant trauma mechanism (67%). The mean GCS-P score was 10.7 \u00b1 3.9. CT scans revealed severe injury in 23.3% of cases. A strong negative correlation existed between GCS-P score and CT severity (\u03c1 = -0.682, P < 0.001). Patients with severe CT findings had significantly lower GCS-P scores (5.9 \u00b1 2.4) than those with mild (12.4 \u00b1 2.1) or normal imaging (14.0 \u00b1 1.6) (P < 0.001). GCS-P is a reliable, practical tool for the early identification of severe intracranial injury, with a strong association with CT severity. Routine implementation of GCS-P scoring can enhance triage, neurosurgical decision-making, and resource allocation in emergency neurotrauma care.

"42487691": "ID: 42487691\nTitle: The potential role of aberrant microglial synaptic pruning in the neurodevelopmental pathogenesis of tourette syndrome.\nAbstract: Tourette syndrome is a neurodevelopmental disorder traditionally attributed to dopamine system hyperactivity within the cortico-striato-thalamo-cortical circuitry. However, classical neurotransmitter hypotheses fail to fully explain the spatiotemporal and developmental specificities of the disorder. Consequently, research focus has shifted toward the neuroimmune microenvironment, specifically the role of microglia. This review aims to comprehensively explore the potential mechanisms of microglia-mediated aberrant synaptic pruning in the pathogenesis of tourette syndrome and to evaluate emerging therapeutic strategies. Methodologically, the study employs a narrative review approach to synthesize current neuroimmunobiology literature to reconstruct the pathological trajectory from early immune dysregulation to targeted interneuron impairment. Additionally, it conceptually explores natural product active monomers through a multi-target network pharmacology framework and assesses the translational potential of engineered nanodelivery systems. The findings indicate that genetic susceptibilities, such as histidine decarboxylase gene mutations, interact with environmental stressors, like maternal immune activation, to induce a chronically primed state in basal ganglia microglia. These primed innate immune cells are hypothesized to execute excessive synaptic pruning against highly vulnerable parvalbumin-expressing fast-spiking interneurons, a process significantly facilitated by the pathological downregulation of presynaptic protective signals. The physical loss of this local gamma-aminobutyric acid-ergic inhibitory network attenuates feedforward inhibition on medium spiny neurons, potentially contributing to macroscopic dopaminergic disinhibition. To address these mechanisms, multi-target natural therapies delivered via intelligent nanoplatforms present a theoretically promising approach to penetrate the blood-brain barrier and reverse pathological microglial phenotypes. Ultimately, this manuscript proposes a perspective of tourette syndrome as a microstructural developmental disorder of the circuitry rather than a mere neurotransmitter imbalance, providing a critical theoretical foundation for developing precise, next-generation neuroimmune-modulating interventions.",

Microglia-specific overexpression of Sestrin2 was achieved by injecting adeno-associated virus (AAV) into the CUS mouse hippocampus. Depressive-like behaviors were assessed using sucrose preference, tail suspension, and forced swim tests. Cognitive function was evaluated by the Morris water maze. Levels of IL-1\u03b2 and IL-6 in the hippocampus and cell supernatants were measured by ELISA. BV2 microglial cells were used for in vitro mechanistic studies. YTHDF1 siRNA and overexpressive lentivirus were used to regulate YTHDF1 expression in vitro. RNA immunoprecipitation was performed to demonstrate the physical interaction between YTHDF1 and Sestrin2 mRNA. Sestrin2 expression was significantly reduced in the hippocampus of CUS mice. Overexpression of Sestrin2 specifically in microglia ameliorated CUS-induced depressive-like behaviors, cognitive impairment, and inflammatory levels. YTHDF1 expression was also reduced in the CUS hippocampus. Mechanistically, YTHDF1 bound to Sestrin2 mRNA and knockdown of YTHDF1 decreased Sestrin2 expression. Molecular biology prediction results showed that positions 1943 and 2,114 of Sestrin2 mRNA are high-confidence N6-methyladenosine (m6A) modification sites. Mutation of the 2,114 site on Sestrin2 mRNA inhibited the effect of YTHDF1 on 3Flag expression. Furthermore, YTHDF1 knockdown promoted IL-1\u03b2 and IL-6 production in BV2 cells, which was reversed by Sestrin2 overexpression. Microglial Sestrin2 alleviates depressive-like behaviors, cognitive impairment and neuroinflammation. YTHDF1 regulates Sestrin2 expression via an m6A-dependent mechanism, and the YTHDF1-Sestrin2 axis may represent a novel therapeutic target for major depressive disorder.",

This review examines how lipids and ketone bodies shape microglial metabolic fitness in the aging brain and in Alzheimer's disease, and how these effects intersect with triggering receptor expressed on myeloid cells 2 (TREM2) signaling and translational biomarkers. Available evidence indicates that early compensatory glycolysis may give way to chronic bioenergetic failure, while cholesterol and lipoprotein trafficking, lipid droplet accumulation, ketone-body signaling, and TREM2-associated lysosomal pathways influence plaque engagement, phagocytosis, and inflammatory responses. The review also considers how apolipoprotein E genotype, brain region, sex, disease stage, and model system condition translation from experimental models to human disease. Fluid, imaging, and tissue readouts are therefore discussed as stage- and context-dependent proxies rather than fixed signatures. Overall, nutritional strategies and microglia-targeted interventions are most likely to be informative when aligned with disease stage and biological context.",
"42488223": "ID: 42488223\nTitle: Near-infrared spectroscopy cerebral oximetry in pediatric congenital heart disease with cardiopulmonary bypass: a narrative review of current evidence and neuroprotection.\nAbstract: Children with congenital heart disease (CHD) often require early surgical repair supported by cardiopulmonary bypass (CPB). Although survival has improved, neurological injury and later neurodevelopmental impairment remain common, motivating continuous perioperative neuromonitoring. Near-infrared spectroscopy (NIRS) provides noninvasive, real-time regional cerebral oxygen saturation (rScO2), reflecting the balance between cerebral oxygen delivery and metabolic demand. This review summarizes evidence on NIRS-derived perioperative rScO2 patterns in pediatric CHD surgery with CPB and examines associations between cerebral oxygenation abnormalities, markers of brain injury, and neurodevelopmental outcomes. rScO2 typically increases during cooling/deep hypothermia but reaches nadirs during low-flow perfusion or circulatory arrest and in early rewarming, suggesting vulnerability windows when oxygen supply-demand mismatch is most likely. Definitions and thresholds for cerebral desaturation vary substantially across studies, yet accumulating data indicate that postoperative cerebral oxygenation-particularly mean levels and cumulative desaturation burden within the first 12-24\u2005h-may correlate with adverse biomarkers or neuroimaging findings and poorer later cognitive performance. Hemodynamic disturbance, oxidative stress, and inflammation may further shape the relationship between rScO2 abnormalities and neurological injury risk. Overall, perioperative rScO2 trends and desaturation burden may support neurological risk stratification and individualized physiological assessment, but standardized metrics, multimodal monitoring strategies, and prospective studies with long-term neurodevelopmental endpoints are needed to define actionable targets.",
"42488390": "ID: 42488390\nTitle: The effect of concurrent neural injuries on hemorrhage.\nAbstract: Spinal cord injury (SCI) is often accompanied by additional tissue damage (polytrauma) that amplifies inflammation and activates pain pathways. The latter has been studied by engaging nociceptive fibers using electrical stimulation or capsaicin caudal to a thoracic SCI. Nociceptive stimulation 1\u202fday after SCI increases hemorrhage, amplifying secondary tissue loss. Noxious stimulation also promotes hemorrhage after a traumatic brain injury (TBI). A common form of polytrauma after SCI involves a TBI. The current study examines whether a concurrent TBI promotes hemorrhage after SCI. This also allowed us to evaluate whether a concurrent SCI promotes brain hemorrhage after TBI. Animals received a thoracic SCI and a concurrent brain surgery (anesthesia alone, craniectomy, or TBI). Other animals received a TBI to the frontal region and a concurrent spinal surgery (anesthesia alone, laminectomy, or SCI). Tissue was collected 24\u202fh later, sectioned, and the extent of brain/spinal cord hemorrhage was quantified. Sham controls were included to verify a remote injury (SCI/TBI) does not induce hemorrhage in the absence of local neural damage. A concurrent TBI with a SCI amplified hemorrhage in the spinal cord. A craniectomy had an intermediate effect on hemorrhage. Additionally, concurrent SCI with a TBI increased hemorrhage in the brain with a more modest effect. The results provide a link between hemorrhage development and concurrent neural injuries, with greater hemorrhage observed after SCI in animals with a concurrent TBI. SCI modestly impacted hemorrhage after TBI. These results provide a basis to further investigate the mechanisms responsible for interactions between multiple neurotraumatic injuries.",

To address this research gap, we utilized data from the Long-term Impact of Military-relevant Brain Injury Consortium (LIMBIC) and the Translational Research Center for TBI and Stress Disorders (TRACTS), two prospective longitudinal cohort studies of veterans and active duty SMs, each containing a wide range of symptom scales, objective assessments, and health-related outcomes. This paper describes the innovative methods used to achieve the initial proof-of-concept harmonization for baseline psychosocial and physical health data from these two large cohort studies. To achieve harmonization, we gathered a multidisciplinary team with clinical and research expertise. We created a list of measures utilized by each study and organized them into larger clinically meaningful domains. When possible, we harmonized full measures, or single items directly, while others needed to be indirectly harmonized, by recoding, aligning categorical levels, and categorizing scales based on established cut scores. We calculated descriptive statistics to summarize and compare data. We then conducted Principal Component Analysis (PCA) for all continuous measures to assess whether site-level effects were observed in the shared variance. A total of 73 variables capturing psychosocial function, sensorimotor, pain, and clinical health factors were harmonized across the LIMBIC and TRACTS studies. There were no differences in sex or ethnicity distributions between the studies. Sensory, social health, and health related clinical data were broadly comparable across cohorts, while pain intensity and headache disability were higher in LIMBIC. PCA analysis suggests data is suitable for pooled analysis. We were able to directly harmonize multiple self-report measures of social well-being and indirectly harmonize other functional and demographic variables. While this initial effort focused on baseline data, the included principles can be employed to harmonize longitudinal data to increase the ability to detect clinical phenotypes to be applied in precision medicine approaches in future research.",
"42488470": "ID: 42488470\nTitle: Electrochemical monitoring of early astrocytic responses underlying the synergistic effect of extracellular matrix softening and hypoxia.\nAbstract: Traumatic brain injury (TBI) disrupts central nervous system homeostasis, leading to extracellular matrix (ECM) softening and localized hypoxia and thus contributing to astrocytic activation and sustained neuroinflammation. But the interplay between ECM softening and hypoxia in regulating astrocytic activation and response remains elusive. To understand this, we developed an in vitro model incorporating tunable-stiffness hydrogels and a precise oxygen-control system to simulate the mechanical and hypoxic microenvironment of TBI. We characterized the activation-related proteins and cytokine production of astrocytes under the in vitro model, and found that soft ECM and hypoxia independently promote astrocytic activation and synergistically activate astrocytes via HIF-1\u03b1/YAP-NF-\u03baB signaling, resulting in astrocytic redox imbalance and neuroinflammation. We further used scanning electrochemical microscopy (SECM) to track the dynamic changes in glutathione (GSH) efflux and membrane integrity in live astrocytes in situ under pathophysiological conditions of ECM softening and hypoxia. The SECM results show that the combined ECM softening and hypoxia progressively impair cellular membrane integrity and promote GSH efflux of astrocytes, corresponding to the early changes in astrocytic function and indicative of an early activation-primed state to exacerbate secondary injury of astrocytes. Last, we found that the lovastatin (a neuroprotective agent) treatment can effectively attenuate astrocytic membrane impairment and decrease GSH efflux, proving the potential of lovastatin to mitigate inflammation and preserve neuroregulatory function. Our work observes the in situ and early state changes of astrocytes under a combined mechanical-hypoxic microenvironment for the first time. The findings offer mechanistic insights into TBI pathogenesis and highlight promising strategies for early therapeutic intervention.",

This systematic review aimed to evaluate the diagnostic and prognostic utility of ECG monitoring in patients with TBI, identify knowledge gaps, and guide future research. Following PRISMA guidelines, we searched PubMed and Google Scholar (January 2020 - March 2025) for studies on adult patients with TBI (\u2265 16 years) who underwent acute ECG assessment (\u2264 72 hours post-injury). The inclusion criteria focused on observational/cohort studies that reported ECG changes, severity correlations, and outcomes. The exclusion criteria were pediatric cases, pre-existing cardiac conditions, and non-English articles. Data were extracted from the eligible studies. Six studies (1,642 patients) revealed ECG abnormalities in 10-88% of cases, increasing with TBI severity (e.g., prolonged QTc in 3% of mild cases vs. 15% of severe cases). Common changes included repolarization issues (QTc prolongation and ST-segment/T-wave alterations), arrhythmias, and conduction disturbances. Abnormalities often resolved within days, improved post-neurosurgery (e.g., reduced QTc), and predicted mortality (e.g., QTc prolongation/ST depression as independent factors) and cardiac dysfunction. ECG changes are prevalent in TBI, correlate with severity, and have prognostic value for risk stratification. Routine monitoring is recommended, and larger, standardized studies are needed to optimize management.",
"42488529": "ID: 42488529\nTitle: Targeting Interleukin-6 Signaling with Reactive-Oxygen-Species-Responsive Hydrogel to Promote Regeneration after Spinal Cord Injury.\nAbstract: Spinal cord injury (SCI) triggers an excessive inflammatory response, characterized by the up-regulation of various inflammatory factors that impede neural regeneration and functional recovery. Interleukin-6 (IL-6) is an early and critical inflammatory mediator observed in lesions post-SCI. Antagonizing the signaling pathway presents a promising strategy to mitigate early inflammation and secondary injury after trauma. Here, we identified specific activation of the IL-6 receptor in neurons and microglia in lesions, indicating their responsiveness to early up-regulated IL-6 signaling within the microenvironment. In\u00a0vitro, neutralizing IL-6 signaling in microglia effectively alleviated their inhibitory effects on neuronal axon growth in conditioned media. Building on this, we developed a reactive-oxygen-species-responsive hydrogel for the sustained local delivery of tocilizumab, an IL-6 receptor antagonist, and implanted it in a complete transection SCI model. In\u00a0vivo, sustained IL-6 receptor blockade effectively reduced early inflammatory cell infiltration, modulated microglial polarization toward an anti-inflammatory phenotype, and fostered neuronal regeneration within the lesion. Importantly, this therapeutic intervention promoted long-term hind limb functional recovery in SCI mice. This study underscores the therapeutic potential of precisely targeting early inflammatory cytokine signaling pathways, particularly IL-6, to improve outcomes after SCI.",

This review systematically examines methodological advances in brain organoid technology, from basic fabrication and brain-region-specific organoids to multicellular assembloids that incorporate microglia and vascular components, with an emphasis on strategies for overcoming fetal-like phenotypes. We surveyed literature published between 2018 and April 2026 that focused on human iPSC-derived organoid models that recapitulate core AD pathologies, including A\u03b2 plaques, tau tangles, neuroinflammation, and blood-brain barrier dysfunction. Key findings demonstrate that organoids effectively capture genotype-phenotype relationships for major AD genes (APP, PSEN1, PSEN2, and APOE\u03b54), enable the dissection of signaling pathway dysregulation (Wnt/\u03b2-catenin), and when combined with CRISPR editing and single-cell multi-omics, reveal cell-type-specific disease mechanisms. Organoids have also been successfully applied to patient-specific \"avatar\" models and high-throughput drug screening, thus advancing precision medicine approaches. However, current technological bottlenecks-including a lack of functional vascularization, batch-to-batch variability, and insufficient standardization-limit the full recapitulation of chronic, age-dependent AD pathology. This review critically evaluates these limitations, addresses ethical considerations surrounding neural organoids, and looks forward to future integration with artificial intelligence, spatial omics, and multi-organ systems to accelerate the translation of organoid-based discoveries into clinical applications.",

This study investigated the neuroprotective potential of Kangen-karyu (KK) in a mouse model of global cerebral ischemia/reperfusion injury induced by bilateral common carotid artery occlusion (BCCAO). Male C57BL/6J mice were subjected to BCCAO followed by reperfusion. KK or nimodipine was administered orally either before or after ischemia. Neurological outcomes, histopathology, and markers of oxidative stress, inflammation, and apoptosis were evaluated. Post-ischemic administration of KK significantly reduced brain edema, neuronal degeneration, and ischemia/reperfusion-induced brain damage, while improving cognitive performance. These effects were associated with decreased phosphorylation of JNK/p38 MAPK and reduced expression of iNOS and apoptosis-related proteins. Post-treatment produced greater benefits than pre-treatment or nimodipine. KK may have therapeutic potential for mitigating global cerebral ischemia/reperfusion-induced brain injury, possibly through modulation of stress- and inflammation-related pathways. Further studies are warranted to validate these findings.",

In particular, whether DEX exerts timing-dependent neuroprotection in the developing brain and the mechanisms underlying such effects are unclear. We investigated the neuroprotective effects of DEX in a neonatal rat double-hit model combining prenatal maternal lipopolysaccharide exposure with postnatal hyperoxia. A tapered DEX regimen was initiated on postnatal day (P)1, P3, or P8 to evaluate the therapeutic window. Lung pathology, survival, hippocampal injury, microglial reactivity, behavioral outcomes, resting-state functional magnetic resonance imaging (rs-fMRI), targeted metabolomics, and microglia-neuron coculture experiments were used to characterize pharmacological efficacy and mechanism. Among the tested regimens, DEX initiated at P3 produced the most consistent protective effects, improving alveolar structure, survival, hippocampal pathology, and microglial reactivity. P3-initiated DEX also improved recognition memory, exploratory/anxiety-related behavior, spatial memory retention, and motor coordination, and was associated with partial restoration of hippocampal functional connectivity. At the molecular level, DEX partially restored hippocampal glutamate/GABA balance, reduced Synapsin I phosphorylation, and normalized VGLUT1/VGAT associated synaptic abnormalities. Mechanistically, microglia-derived IL-1\u03b2 promoted neuronal ERK/Syn1 activation, whereas DEX interrupted this inflammatory signaling axis in a microglia-neuron coculture system. Targeted metabolomics and perturbation experiments further showed that DEX increased Acod1-dependent itaconate reprogramming under inflammatory priming, thereby suppressing microglial IL-1\u03b2 and downstream neuronal P-Syn1/Syn1 signaling. These findings identify a developmentally sensitive therapeutic window for DEX neuroprotection in neonatal BPD-associated brain injury and suggest that microglial Acod1-itaconate-dependent regulation of IL-1\u03b2/ERK/Syn1 signaling contributes to its central protective effects. This study expands the pharmacological interpretation of DEX beyond pulmonary benefit and supports an immunometabolic framework for understanding corticosteroid actions in the developing brain.",

However, emerging evidence indicates that adaptive immunity may also contribute to disease heterogeneity and progression. These disorders should not be considered classical autoimmune diseases, but they may display autoimmune-like signatures, including neural antigen-specific T cell responses, clonal expansion of T cells in blood or cerebrospinal fluid, CNS infiltration of adaptive immune cells, and brain-targeting autoantibodies. Recent studies have linked \u03b1-synuclein-specific T cell reactivity to early Parkinson's disease, identified clonally expanded CD8+ T cells in Alzheimer's disease cerebrospinal fluid, and provided direct evidence of adaptive immune involvement in Lewy body dementia, including altered peripheral immunophenotypes and CD4+ T cell-associated neurodegenerative mechanisms. Experimental tauopathy models further show that microglia-mediated T cell infiltration can drive neurodegeneration. Humoral autoreactivity and progression-associated immune changes further suggest that adaptive immune profiles may help define biologically distinct dementia subgroups. In this mini review, we summarize evidence connecting peripheral immune activation, intrathecal adaptive immune remodeling, and CNS pathology in neurodegenerative dementias. We also discuss how longitudinal blood-CSF profiling, single-cell/TCR/BCR sequencing, autoantibody profiling, and mechanistic validation may clarify whether these immune signatures are pathogenic, compensatory, or bystander responses.",

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.",

Dysregulated SIRT activity has been extensively studied in aging, metabolic syndrome, cardiovascular disease, neurodegeneration, cancer, and immune disorders. However, robust human evidence and SIRT-targeted therapies are lacking. Transgenic mouse models serve as key platforms to study gene function and guide therapeutic development. This review synthesizes evidence from Sirt1-7 transgenic mouse models regarding the core cellular processes governed by SIRTs: metabolism, genome integrity, stress resistance, immunity, and autophagy, and illustrates their operation across different organ systems. By comparing global, tissue-specific, and inducible knockout (KO) and overexpression (OE) models of cardiovascular, respiratory, digestive, nervous, endocrine, urogenital, musculoskeletal, malignant, and immune diseases, we identified central regulatory SIRTs (SIRT1, SIRT3, and SIRT6), context-dependent modifiers (SIRT2, SIRT4, SIRT5, and SIRT7), and their organ- and cell type-specific functions. We also summarize representative small-molecule SIRT activators, inhibitors, and degraders, covering both clinical and preclinical studies, and highlight where contradictions and knowledge gaps remain. Together, these analyses help clarify which aspects of SIRT modulation are most promising and under what isoform, tissue, and disease contexts they should be pursued for the development of SIRT\u2011targeted therapies in human disease.",

It is characterized by progressive retinal ganglion cell (RCG) loss, optic nerve-head damage, irreversible visual field loss, and sometimes, increase in intraocular pressure (IOP). Existing therapeutic strategies target elevated IOP, the only modifiable risk factor for the disease, and fail to address the co-current neurodegeneration in the posterior segment of the eye. This demonstrates a huge gap in effective glaucoma therapy and highlights the need for multitargeting treatments that simultaneously reduce IOP in the anterior segment and mitigate neurodegeneration in the posterior segment of the eye. There is evidence that gasotransmitters such as nitric oxide (NO) and hydrogen sulfide (H2S) could be beneficial in the treatment of glaucoma due to their ability to reduce IOP and mitigate neurodegeneration in the mammalian eye; while the second gasotransmitter, carbon monoxide (CO) can relax trabecular meshwork, enhance ocular perfusion and mitigate retinal neuronal apoptosis. Since current glaucoma therapies focus on IOP reduction, the multi-targeting nature of these gasotransmitters renders them as viable drug candidates to shift glaucoma therapy from IOP-targeting to multiple targeting therapeutic agents with improved patient outcomes. This review provides an overview of the \"unmet\" need in glaucoma therapy, summarizes current knowledge on the physiology of gasotransmitters and discusses their potential role as multitargeting therapeutic agents in glaucoma.",

Among the multifactorial mechanisms implicated in AD, reciprocal interactions between brain-derived neurotrophic factor (BDNF) and amyloid-\u03b2 (A\u03b2) have attracted increasing attention as a convergent axis linking amyloid pathology to impaired neurotrophic support. BDNF promotes neuronal resilience, synaptic plasticity, and cognitive function primarily through the activation of its high-affinity receptor, tropomyosin receptor kinase B (TrkB), and downstream signaling pathways, including PI3K-Akt and MAPK/ERK. Human postmortem and biomarker studies mainly support associations between reduced BDNF signaling, synaptic dysfunction, and AD-related pathology. In contrast, cell-based and animal studies provide mechanistic evidence that BDNF/TrkB signaling may influence amyloid precursor protein (APP) processing and neuronal resistance to A\u03b2-induced stress. Conversely, mechanistic studies indicate that A\u03b2 accumulation can suppress CREB-dependent BDNF expression, disturb BDNF transport, and impair TrkB receptor function. Thus, the BDNF-A\u03b2 relationship is better interpreted as a stage- and context-dependent pathogenic coupling rather than a simple causal loop. This review synthesizes evidence from human studies, animal models, and cellular systems to clarify how BDNF-A\u03b2 dysregulation contributes to AD progression and to discuss the translational potential of BDNF-oriented interventions.",

In a genetic Val66Met rat model, we compared the effects of a high-enrichment/high-complexity early-life environment (HE) and a low-enrichment/low-complexity environment (LE). Body weight was higher in both male and female HE rats compared to LE rats. Anxiety-like behavior on a plus maze or in an open field was enhanced in both male and female HE rats compared to LE rats. In contrast, following HE, only in females, adrenal weight was higher, and in the forced swim test, immobility was lower, and swimming was higher. Body weight and behavioral changes did not differ between BDNF genotypes. Fear conditioning and extinction were not affected. The effect of HE vs. LE condition on expression of BDNF, the antioxidant transcription factor, NRF2, and the glucocorticoid receptor, NR3C1, in the ventral hippocampus varied depending on genotype, and most of these changes were again only seen in females. There were no effects on the expression of the stress markers, SGK1 and FKBP5, or the mineralocorticoid receptor, NR3C2. These results show persistent effects of early-life environment on anxiety-like behavior and gene expression of BDNF and stress markers in adulthood, with some effects showing sex- and Val66Met genotype specificity. These results may be important for our understanding of factors involved in the development of clinical anxiety and depression, and also have implications for animal welfare in the laboratory setting.",

Despite its therapeutic promise, the clinical application of HKL is severely restricted by its hydrophobicity and low oral bioavailability. The present review systematically summarized 99 studies (90 original articles and nine reviews) on the pharmacological profile of HKL. It detailed HKL's molecular interactions with key signaling targets, such as sirtuin 3, NOD-like receptor family pyrin domain containing 3-cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes, Yes-associated protein/transcriptional coactivator with PDZ-binding motif, adenosine monophosphate-activated protein kinase and signal transducer and activator of transcription 3, which underly its efficacy against cancer (ovarian, liver, breast, colorectal, and lung), neurodegeneration (Alzheimer's and Parkinson's disease), metabolic disorders (diabetes, nonalcoholic fatty liver disease and obesity) and inflammatory and infectious diseases. Furthermore, the present review critically evaluated recently developed strategies to overcome its pharmacokinetic limitations. The present review offered an updated theoretical basis for understanding the structure-activity relationship of HKL and provided insights into its translation from bench to bedside.",

However, how diffuse injury differentially alters hippocampal subregions across time remains incompletely defined. Here, we used a mouse closed-head injury model to characterize early transcriptomics, subacute-to-chronic electrophysiology, dendritic spine morphology, and delayed immunoreactivity for glial fibrillary acidic protein (GFAP), ionized calcium-binding adapter molecule 1 (IBA1), and the pan-leukocyte marker CD45. Bulk RNA sequencing at 9, 24, and 72\u2005h post-injury revealed induction of immediate early genes and neuronal excitability transcripts at 9\u2005h alongside inflammatory pathways. These neuronal signatures diminished by 24-72\u2005h while immune-associated programs persisted. Ex vivo field recordings in CA1 and dentate gyrus at 1, 3, and 6 weeks post-injury revealed reductions in synaptic strength in both regions at 1 week. Dentate gyrus deficits persisted at 3 weeks but recovered by 6 weeks, whereas CA1 showed depression at 1 and 6 weeks with relative sparing at 3 weeks. Fibre volley recruitment was preserved across regions and timepoints, arguing against gross presynaptic loss. Population spike thresholds were reduced in both regions, indicating increased neuronal excitability that persisted in CA1 but partially recovered in dentate gyrus. DiOlistic labelling and spine reconstruction revealed stable total spine density, but spine class composition showed sex-dependent injury effects in CA1 with altered mushroom and stubby proportions in males. Immunohistochemistry across 1-8 weeks post-injury revealed cortical gliosis but no injury-related changes in hippocampal GFAP or IBA1, while CD45 immunoreactivity increased in a delayed, sex-dependent manner within hippocampus. Together, these findings show that a single closed-head injury produces sustained hippocampal circuit dysfunction characterized by reduced synaptic strength and increased neuronal excitability, with region-dependent recovery dynamics, preserved presynaptic recruitment, and delayed hippocampal CD45 increases that do not parallel local glial activation.",

Mounting evidence from both experimental and clinical studies has highlighted the pivotal role of T helper 17 (Th17) cells and their proinflammatory cytokines, especially interleukin-17A (IL-17A), in mediating neuroinflammation similar to that seen in experimental autoimmune encephalomyelitis (EAE) and multiple sclerosis (MS) models. REV-ERBs are nuclear receptors that act as transcriptional repressors and regulate immune responses, circadian rhythm, and metabolism. Synthetic REV-ERB agonists, such as SR9009, SR9011, and SR12418, have demonstrated selective suppression of Th17 differentiation and function, reduction of disease severity, and improved safety profiles in preclinical autoimmune models. In addition to Th17 differentiation, REV-ERB's role in other components of the immunomodulating system is ever-growing. Preclinical and translational data support the further exploration of REV-ERB agonists as a potential addition to the targeted immunomodulatory therapies for canine MUO. By continuing to investigate REV-ERB compounds as a component of MUO therapy, researchers can assess their potential for improved efficacy and reduce the side effects associated with traditional immunosuppressive regimens. This review integrates mechanistic insights from immunology, circadian biology, and experimental models, and outlines future directions for clinical translation, highlighting the relevance of REV-ERB agonists in advancing veterinary neuroimmunology and in informing comparative approaches to human neuroautoimmune disease.",

This narrative review synthesises evidence on the epidemiology, patterns, harms and treatment gaps for OUD in Nigeria and identifies priorities for policy and research. We searched PubMed/MEDLINE, Embase, PsycINFO, the Cochrane Library, African Journals Online, Google Scholar and grey literature from 2005 to 2024 for Nigerian data on non-medical opioid use, clinical harms, opioid agonist therapy (OAT) services, barriers and community supports. Findings were thematically synthesised using Braun and Clarke's framework, with quality appraisal using Joanna Briggs Institute tools and the SANRA scale. Thirty studies were included. The 2019 national drug use survey estimated past-year opioid use at 4.7% (approximately 4.6 million people), with institution-based surveys reporting high lifetime misuse among undergraduates. Reported harms included overdose, seizures, psychiatric comorbidity and injectable pentazocine dependence with severe soft-tissue infections. OAT availability remains highly centralised, with limited community recovery infrastructure. Nigeria's OUD burden is substantial but unevenly characterised, highlighting the need to decentralise OAT, integrate addiction training, strengthen surveillance and expand community supports.",

Whereas the general use of CT for all patients with mTBI is inefficient and wasteful, the omission of a clinically important brain injury is not desirable. Several guidelines have been developed to assist physicians in determining who actually needs a head CT. For this reason, the Canadian CT Head Rule (CCHR) and the New Orleans Criteria (NOC) were compared in this study on their efficacy in predicting surgically significant brain injuries and the need for neurosurgical intervention. The research was a prospective cross-sectional study at a level 1 trauma centre that received ethical approval from the Hospital. Consenting adult patients who presented with mild TBI within 24 hours were recruited. They were assessed with the NOC and CCHR, whose decisions were compared with each other and with CT head findings. A total of 103 patients were successfully enrolled, males were 91 and females were 12, with a mean age of 32.48\u00b112.27 years old. The NOC guideline had a sensitivity (88.6%), specificity (21.4%), positive predictive value (47.0%) and negative predictive value (70.6%) of clinically significant brain injury; while CCHR guideline showed sensitivity (86.4%), specificity (30.4%), positive predictive value (49.4%) and negative predictive value (73.9%) of clinically significant brain injury (table 3), however, statistically were not significantly different with P-value of 0.39. Similarly, there was no statistically significant difference between the two guidelines for the need for neurosurgical intervention, as the P-value was 0.48. Following the findings, this study suggests that either NOC or CCHR is safe to be used for ordering a head CT for patients with mild TBI.",

This hypothesis-testing study investigates disrupted BCAA (branched-chain amino acid) catabolism as a key mechanism of ischemic brain damage and evaluates BCKDK (branched-chain \u03b1-keto acid dehydrogenase kinase) as a novel therapeutic target. Mouse primary cortical neurons subjected to oxygen-glucose deprivation and brain tissue from a mouse acute ischemic stroke model were used as experimental systems. Untargeted metabolomics and metabolic flux analysis were used to characterize BCAA metabolism in both models. In vivo pharmacological inhibition or in vitro knockdown of BCKDK was performed using BT2 treatment or RNA interference. Primary outcome variables included infarct volume, BCKDH (branched-chain \u03b1-keto acid dehydrogenase) enzyme activity, neuronal viability, and markers of energy metabolism and glutamate excitotoxicity. Between-group differences were evaluated using 1-way ANOVA; data are presented as mean \u00b1 SD with 95% CIs and corresponding P values. Metabolomics analysis of oxygen-glucose deprivation-exposed primary neurons revealed impaired BCAA catabolism and significant BCAA accumulation compared with normoxic controls. In ischemic mouse brain tissue, BCKDH activity was significantly suppressed, and BCKDK expression was markedly upregulated relative to sham-operated animals. Both pharmacological and genetic suppression of BCKDK substantially reduced cerebral ischemic injury, as evidenced by decreased infarct volume and improved neuronal survival (95% CI and P values per comparison). Mechanistically, ischemia-induced BCKDK expression via HIF-1\u03b1 (hypoxia-inducible factor 1\u03b1)-mediated transcriptional activation, which inhibited BCAA conversion to tricarboxylic acid cycle substrates, thereby potentiating energy deficiency and glutamate excitotoxicity. These data identify BCKDK as a novel hypoxia-responsive factor whose upregulation drives disrupted BCAA catabolism as a key mechanism of ischemic neuronal injury. BCKDK represents a promising therapeutic target for cerebral ischemia, directly supported by both in vitro and in vivo experimental evidence presented here.",

Retrospective secondary analysis of a multicentre longitudinal cohort. Adults aged 16 years or older with operationally defined severe traumatic brain injury, private residence at 1 year, linked 5-year follow-up, and complete data for 4 profile indicators. Latent class analysis used 5-year rehospitalization, PHQ-9, GAD-7, and Satisfaction With Life Scale scores dichotomized with prespecified clinically interpretable thresholds. External rehabilitation outcomes and early associated factors were examined descriptively and with multivariable logistic regression. Among 2,835 participants, a 2-class solution identified a lower-vulnerability profile (n\u2009=\u20092,361) and a multidomain vulnerability profile (n\u2009=\u2009474). The latter showed more depressive symptoms, anxiety symptoms, low life satisfaction, and rehospitalization, with poorer 5-year functioning, participation, health, productive status, and higher frequency of non-private residence. Better 1-year global outcome was protective; female sex, preinjury illicit drug use, and living alone at 1 year were associated with assignment to this profile. Home return after severe traumatic brain injury should be treated as a transition point for longitudinal rehabilitation surveillance.",

Here, we found that photobiomodulation (PBM) markedly reduced cerebral CD8+ T cells infiltration in the cortex of AD (APP/PS1 and 3\u00d7Tg) mice, thereby improving cognition, and alleviating AD-related pathology by mitigating neuronal damage and gliosis. Immunofluorescence and transcriptomic analyses revealed that PBM inhibited the release of chemokines and pro-inflammatory cytokines from microglia, reducing endothelial adhesion molecules-mediated T cell migration. Concurrently, reduced secretion of tumor necrosis factor-\u03b1, interleukin-1\u03b1, and complement component 1q by pro-inflammatory microglia further diminished neurotoxic A1 astrocyte induction. Genetic overexpression or pharmacological inhibition further validated that PBM disrupted microglia NOD-like receptor protein 3 inflammasomes activation, attenuating astrocyte reactivity and T cells recruitment. These findings collectively suggest that the PBM-induced modulation of crosstalk between microglia, astrocytes, and CD8+ T cells is closely related to cognitive improvement. Reprogramming central-peripheral immune crosstalk with PBM resolves neuroinflammation and restores cognition in AD models-a translatable strategy for combating neurodegeneration.",

AD patients frequently experience recurrent systemic inflammatory insults from comorbid conditions, which act as\u00a0\"secondary-hits\" believed to worsen cognitive decline. The impact of these secondary insults \u00a0on astrocyte-mediated neurovascular regulation remains unknown. We applied intravital two-photon microscopy to longitudinally investigate astrocytic Ca2 + dynamics and functional hyperemia during sensory stimulation in APP/PS1dE9 mice before and during secondary lipopolysaccharide (LPS)-induced systemic inflammation. AD mice exhibited diminished stimulation-evoked astrocytic Ca2 + activity, while functional hyperemia remained largely preserved. LPS further suppressed astrocytic Ca2 + responses and produced temporally specific vascular alterations, with AD and wild-type mice following divergent inflammatory trajectories. Our findings provide the first in vivo longitudinal characterization of how secondary systemic inflammation disrupts astrocyte-mediated neurovascular regulation. The selective vulnerability of astrocytic Ca2 + signaling relative to vascular output implicates recurrent inflammatory insults as a clinically relevant contributor to neurovascular dysfunction in preclinical AD.",

The human dental pulp stem cell (hDPSC) secretome is a promising cell-free therapeutic candidate containing neurotrophic, antioxidant, and immunomodulatory factors. Here, we investigated its therapeutic effects in a photothrombotic mouse model of ischemic stroke and CoCl2-induced hypoxic BV2 microglial cells. Proteomic profiling identified antioxidant-associated proteins, including SOD2, GSR, and GSTP1, and microglial phenotype-related candidates, including GRN, CSF1, and LRP1. hDPSC secretome treatment reduced stroke-induced infarct volume and attenuated stroke-increased neuronal apoptosis, neuronal ROS accumulation, and NF-\u03baB-associated inflammatory signaling in the cortex and hippocampus. It also shifted microglial marker expression toward an M2-associated profile and improved stroke-impaired hippocampal neurogenesis, vascular remodeling, and synaptic organization. Proteomic analyses further identified coordinated changes in pathways related to oxidative phosphorylation, inflammatory responses, calcium signaling, SNARE-associated vesicular transport, and ROBO-Rho-associated cytoskeletal remodeling. These molecular and cellular changes were associated with improved motor coordination, spatial learning and memory, contextual memory, and anxiety-like behavior. These findings support the hDPSC secretome as a cell-free therapeutic candidate for post-stroke functional recovery linked to redox, inflammatory, neurovascular, and synaptic remodeling.",

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.",
"42489330": "ID: 42489330\nTitle: CYP3A4-mediated Effects of Cranberry and Pomegranate Juices on Alprazolam Pharmacodynamics.\nAbstract: Alprazolam, a frequently prescribed anxiolytic, is extensively metabolized in the liver mostly by the cytochrome P450 3A4 (CYP3A4) enzyme. Cranberry and pomegranate juices, often suggested for their possible therapeutic effects in kidney stone management, have been identified as strong inhibitors of CYP3A4. This raises considerable concerns about possible drug-food interactions that could modify the pharmacodynamic profile of alprazolam. This study aimed to comprehensively assess the pharmacodynamic interactions between alprazolam and these juices, focusing on their collective impact on behavioral and histological results. Molecular docking studies were conducted utilizing AutoDock Vina to assess the binding affinities of active compounds from cranberry and pomegranate juices to the CYP3A4 enzyme, resulting in binding energies of -9.2 and -9.3 kcal/mol, respectively. In vivo tests were performed on adult male Wistar albino rats, which were divided into five experimental groups: control, alprazolam alone, and alprazolam co-administered with cranberry juice, pomegranate juice, or a combination of both. Pharmacodynamic interactions were evaluated via behavioral analyses using the Elevated Plus Maze, Rotarod, and Y-Maze tests to assess anxiety, motor coordination, and cognitive performance. Furthermore, histological analyses of brain tissues were performed to detect neuronal changes and evaluate the degree of neurodegeneration linked to the treatment. Molecular docking analyses revealed strong binding affinities of anthocyanins from cranberries and ellagic acid from pomegranates to the CYP3A4 enzyme, suggesting their ability to inhibit its activity. Behavioral tests indicated considerable deficits in memory and motor coordination in groups receiving cranberry or pomegranate drinks in conjunction with alprazolam, relative to the alprazolam-only and control groups. Histopathological examination of brain tissues supported these findings, revealing a significant elevation in neuronal degeneration in the coadministration groups compared to controls, indicating a synergistic effect on neurotoxicity. The pharmacodynamic changes observed suggest that the coadministration of cranberry and pomegranate juices with alprazolam alters the drug's effects, likely due to CYP3A4 inhibition by the juices' phytochemicals. These interactions may enhance alprazolam's neuropharmacological effects, resulting in an increased risk of cognitive and motor impairments. These findings underscore the clinical importance of monitoring food-drug interactions, especially in patients using natural products concurrently with CNS-active medications. This study highlights significant pharmacodynamic interactions between alprazolam and cranberry/pomegranate juices, highlighting their potential to influence the drug's therapeutic effectiveness and safety profile. The findings highlight the essential necessity for monitoring when concurrently administering these natural medicines with alprazolam, as their simultaneous usage may result in altered pharmacological effects and increased risk of adverse effects.",

We evaluated changes in helmet use, clinical outcomes, and short-term direct institutional costs following repeal. In this multicenter retrospective cohort study, motorcycle crash patients treated at five ACS-verified Level I-III trauma centers in eastern Nebraska before and after repeal were compared by law era and helmet status. Helmet-use trends were assessed using segmented binomial logistic regression. Cost analyses were restricted to patients with positive direct institutional costs using survivor-only and log-transformed models. Among 467 patients (241 pre-repeal, 226 post-repeal), helmet use declined from 84.2% to 20.4% after repeal (p<0.001). Segmented regression demonstrated an immediate reduction in helmet use after repeal (OR 0.17, 95% CI 0.06-0.44; p<0.001), consistent with adjusted individual-level analysis (aOR 0.04, 95% CI 0.03-0.07; p<0.001). Post-repeal, non-helmeted riders had greater unadjusted head-injury burden and more neurosurgical interventions. After adjustment, non-helmeted status remained independently associated with neurosurgical intervention (aOR 3.10, 95% CI 1.03-9.35; p=0.044), but not BIG score \u22652, severe traumatic brain injury composite, or mortality. Adjusted log-transformed analyses showed lower short-term direct institutional costs among non-helmeted riders (cost ratio 0.68, 95% CI 0.54-0.86; p=0.001), likely reflecting differences in injury patterns and procedural utilization rather than reduced economic burden. Nebraska's helmet-law repeal was associated with an immediate and sustained reduction in helmet use. Non-helmeted riders had higher adjusted odds of neurosurgical intervention despite similar adjusted severe brain injury and mortality outcomes. Lower short-term institutional costs should not be interpreted as economic neutrality because they exclude downstream rehabilitation, disability, productivity losses, and societal costs.",

This study examined PF and PI in a treatment-seeking mTBI sample and tested whether these processes operate through distinct pathways linking post-concussion symptoms (PCS), functional disability, and psychological distress. Participants were 173 adults with mTBI recruited from outpatient concussion rehabilitation services in New Zealand. Participants completed measures of PCS (Rivermead Postconcussion Symptom Questionnaire), disability (WHODAS-12), psychological distress (DASS-21), PI (reactive avoidance; AAQ-ABI), and PF (Personalized Psychological Flexibility Index; PPFI). Structural equation modeling tested a parallel mediation model in which PCS and disability predicted distress indirectly via PI and PF. Three models were estimated, substituting PPFI facets (behavioral engagement, acceptance, harnessing). Across the three structural equation models, overall model fit was adequate, with the behavioral engagement model demonstrating excellent fit. Higher reactive avoidance was consistently associated with greater psychological distress, and a history of a mental health conditions, across all models. Reactive avoidance mediated the relationship between PCS and distress in the behavioral engagement and harnessing models. Behavioral engagement and acceptance were each independently associated with lower psychological distress, whereas harnessing showed a small positive association with distress. These facets did not mediate the relationship between PCS and psychological distress. No serial mediation effects between reactive avoidance and PF on psychological distress were observed. This study demonstrates that PF and PI represent related but distinct transdiagnostic processes shaping psychological outcomes following mTBI. Reactive avoidance emerged as a key mechanism linking PCS to psychological distress, while behavioral engagement and acceptance were independently associated with lower distress. By delineating these processes, the findings extend existing mTBI research and offer clinically relevant insights with the potential to inform transdiagnostic psychological interventions.",

However, some carriers show \"clinical resilience\", maintaining their cognition despite high risk.ObjectiveWe hypothesized that the glymphatic system, the brain's waste clearance pathway, may attenuate APOE \u03b54-mediated neurodegeneration, and tested this in two independent cohorts.MethodsWe analyzed 625 cognitively normal older adults from the Alzheimer's Disease Neuroimaging Initiative (ADNI) discovery cohort and 447 amyloid-positive participants from the preclinical Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) validation cohort. Glymphatic function was estimated using the analysis of diffusional kurtosis imaging along the perivascular space (DTI-ALPS) index in ADNI and choroid plexus (CP) 18F-Flortaucipir PET uptake in the A4 study. Primary outcomes were clinical conversion to dementia (ADNI) and hippocampal tau pathology (A4).ResultsIn the discovery cohort, we observed a trend toward ALPS \u00d7 APOE4 interaction (p\u2009=\u20090.057, not reaching conventional statistical significance). Carriers with preserved function (high ALPS) showed a reduced conversion risk (hazard ratio\u2009=\u20090.52, 95% CI: 0.27-0.99) compared to those with low function. In the validation cohort, glymphatic interface dysfunction (higher CP tau) strongly predicted hippocampal tau burden (p\u2009<\u20090.0001). However, the gene-specific interaction was not replicated (p\u2009=\u20090.928); clearance failure predicted pathology regardless of genotype. Exploratory fluid biomarker analyses in ADNI did not reveal significant interactions.ConclusionsThese findings suggest that preserved glymphatic function is associated with clinical resilience in APOE \u03b54 carriers, though the interaction was borderline (p\u2009=\u20090.057) and should be considered hypothesis-generating. The strong pathological associations with clearance integrity highlight a biologically plausible mechanism in AD pathogenesis that warrants further investigation.",

Recent evidence from healthy aging shows that personality traits can de-differentiate over time, suggesting a decline of coherence of traits with age. Whether such personality de-differentiation also occurs in neurodegeneration and how personality and cognitive changes relate remains unknown.ObjectiveThis study aimed to examine structural changes in personality traits in individuals with AD-like dementias, using the HEXACO personality model administered cross-sectionally to informants and to a control group of informants of healthy older adults, and explore dimensional changes in the relationship between reported changes in personality and cognition.Methods207 informants of persons with AD-like dementia and 201 informants of healthy older adults completed the Hexaco Adjective Scales, referring both to the present time and to perceived changes in personality, and a questionnaire (e-Cog) to assess cognitive changes.ResultsPrincipal component analysis revealed a simplified personality structure in persons with AD but not in healthy older adults, with Emotionality not emerging as an independent factor in persons with AD. Network analyses indicated significant links between personality trait changes and declines across cognitive domains that differed between the two groups.ConclusionsAD-like dementias are characterized by a reduced differentiation of personality structure paralleling the simplification of cognitive organization, with the strongest impact observed in the Emotionality domain.

Timely and specific screening is crucial for proper management. Cog-First is a tablet-based self-assessment of executive functions, memory, and attention lasting approximately 20 min. This study aimed to develop the English version of Cog-First and evaluate its feasibility. A two-phase study was conducted. Phase 1 involved a rigorous translation and cultural adaptation process, following established guidelines. Phase 2 consisted of an exploratory comparison between MoCA and Cog-First scores in individuals with ABI. The English version of Cog-First was developed. Practitioners highly rated the relevance and applicability. Strong agreement (90%) was observed for memory, attention and inhibition sub-tests. About 90% of ABI participants expressed a high level of satisfaction. Exploratory analyses showed an association between MoCA and Cog-First scores (p\u2009=\u20090.037, r\u2009=\u2009.46). This study successfully translated and culturally adapted Cog-First into English and demonstrated its feasibility and acceptability in English-speaking individuals with ABI. While further research is required to explore its psychometric properties, normative values and clinical utility comprehensively, Cog-First might enhance the detection of subtle cognitive deficits and inform targeted rehabilitation strategies.",

Extracellular A\u03b2 deposition in the isocortex is observed before substantial NFD develops, but in the allocortex (temporal lobe) there are no A\u03b2 deposits in 50% of subjects despite extensive NFD. Cytoskeletal lesions in the allocortex consist of atrophic grid cells, abundant pretangles, neuropil threads, neurofibrillary tangles, and neuritic plaques; isocortical sites show either no NFD at all or only minimal NFD presenting as solitary pretangles or tangles, neuropil threads, or droplet degeneration spheres from ferroptotic neurons. Presence of degenerating grid neurons in entorhinal cortex coincides with microglial apoptosis.ConclusionsNeuroprotection via ferritin expression and A\u03b2 deposition is more effective in the isocortex than in allocortex. Findings support the hypothesis that degeneration or death of neuroprotective microglia promotes neuronal degeneration.",

This review provides an integrative overview of the molecular and biochemical modulators governing synaptic plasticity and their disruption in AD. We discuss how the collective impairment of A\u03b2 aggregation, tau pathology, calcium imbalance, oxidative stress, and neuroinflammation affects dendritic spine morphology and synaptic connectivity. Particular attention is given to neurotrophins such as brain-derived neurotrophic factor and TrkB signaling, hormonal influences, likewise glucocorticoids, estrogens, testosterone, endocannabinoid pathways, lipid and cholesterol regulators like ApoE and lipid rafts, and epigenetic mechanisms that modulate synaptic resilience. We further evaluate the therapeutic potential of pharmacological agents, including cholinesterase inhibitors, NMDA receptor modulators, and multi-target directed ligands alongside nutraceuticals such as resveratrol, curcumin, omega-3 fatty acids, Withania somnifera, and Bacopa monnieri. Emerging technologies, including iPSC-derived neuronal models, optogenetics, and advanced neuroimaging biomarkers like SV2A PET, cerebrospinal fluid/plasma neurogranin, are also highlighted for their role in elucidating and monitoring synaptic integrity. Ultimately, targeting the biochemical modulators of synaptic plasticity offers a promising avenue for AD therapy, especially through combinatorial and precision-medicine strategies aimed at restoring synaptic function and cognitive performance.",

Transcranial direct current stimulation (tDCS) and computer-based cognitive rehabilitation (CBCR) have been used in cognitive rehabilitation patients with TBI. This review aims to explore the effects of integrating tDCS and CBCR on cognition post-TBI. \"PsycINFO, PubMed, EMBASE, MEDLINE, SCOPUS, Web of Science, PEDro, and CINAHL\" were explored until March 2026. Randomized studies that integrated tDCS and CBCR and included at least one outcome measure evaluating cognitive function in patients with TBI were included. The Cochrane Risk of Bias 2 (RoB 2) instrument was employed to assess the risk of bias. Four studies involving 115 participants met the inclusion criteria. Two studies reported significant improvements in executive function and working memory after combining tDCS and CBCR compared with no-intervention controls. The other two studies found no significant differences between groups in memory, attention, or executive function outcomes after combining tDCS and CBCR compared with combining tDCS and CBCR. Overall, evidence on the effects of combining tDCS and CBCR is limited. Additional high-quality studies with consistent treatment protocols and long-term follow-up are strongly warranted to understand the effects of the intervention on cognition in individuals with TBI.",

However, its mechanism of action is not completely understood. One proposed mechanism involves the modulation of central and peripheral inflammatory circuits. This exploratory study enrolled 28 participants (11 healthy controls [HC] and 17 patients with chronic back and/or leg pain of various origin). Pain intensity (Numeric Rating Scale), sleep quality (Pittsburgh Sleep Quality Index), mood (Beck Depression Inventory), disability (Oswestry Disability Index), and levels of pro- and anti-inflammatory cytokines (adiponectin, ghrelin, interleukin [IL]-10, high-mobility group box 1-protein, tumor necrosis factor alpha, IL-6, IL-1\u03b2, leptin) were collected at baseline and after three months of burst SCS and compared with HC. A total of 11 men and six women (mean age 68.4 \u00b1 11.2 years) underwent permanent SCS implantation. Pain intensity significantly decreased at follow-up (p < 0.001), accompanied by improvements in sleep quality (p = 0.002), mood (p = 0.001), and disability (p < 0.001). At baseline, proinflammatory tumor necrosis factor alpha levels were significantly elevated (p = 0.006), whereas anti-inflammatory IL-10 levels were significantly reduced compared with HC (p = 0.004). At follow-up, IL-10 levels increased, attenuating the difference between patients and HC such that no statistical significance was observed. Levels of pro- and anti-inflammatory cytokines showed no significant correlations with clinical outcome measures. Consistent with previously published data, we found a proinflammatory profile in patients with chronic pain at baseline. After three months of burst SCS anti-inflammatory IL-10 was increased along with improved pain and functional capacity. However, a causal relationship between burst SCS and neuroinflammatory mediators in chronic back and/or leg pain could not be established.",
"42489669": "ID: 42489669\nTitle: The missing link: Piccolino is essential for tethering synaptic vesicles to rod photoreceptor ribbons.\nAbstract: Retinal photoreceptors transmit light signals to their postsynaptic neurons with high precision, speed and without fatigue. This high-throughput neurotransmission relies on a sophisticated molecular machinery centered on a presynaptic organelle, the synaptic ribbon (SR). A hallmark of SRs is the recruitment of synaptic vesicles (SVs) from the cytoplasmic SV pool via \"tethering\". However, the identity of the tether and the mechanism underlying SV tethering are unknown. Here, we show that cell-specific deletion of the SR-associated protein Piccolino from rod photoreceptors disrupts SR morphology and ablates SV tethering. Nanoscale epitope mapping suggests that Piccolino acts as an SV tether by extending its N terminus away from the SR into the SV-filled terminal cytoplasm. With in silico modeling and protein lipid-binding assays, we demonstrate that an amphipathic liquid packing sensor motif (ALPS) at the N terminus of Piccolino binds SV-like liposomes, implicating this interaction as the mechanism underlying SV tethering. Together, our findings identified Piccolino as the molecular link between the SR and SVs.",

Here, curcumin was evaluated as a dietary bioactive against Salmonella-induced enteritis using in silico target-network analysis, macrophage assays and a mouse infection model. Target-network analysis identified 79 shared targets associated with curcumin and intestinal inflammation. In vitro, macrophages were treated with curcumin at 40 and 80 \u03bcM before stimulation with lipopolysaccharide or Salmonella Enteritidis infection. In vivo, mice were challenged with S. Enteritidis and orally gavaged with curcumin at 100 or 200 mg per kg body weight. Curcumin inhibited LPS- and Salmonella-induced NF-\u03baB activation in J774-Dual/RAW264.7 macrophages, decreased IL-1\u03b2, IL-6 and TNF-\u03b1, increased IL-10, and reduced lactate dehydrogenase release by over 35%. In infected mice, curcumin alleviated clinical deterioration (weight loss and hemolysis), attenuated liver and spleen injury, lowered tissue bacterial burden by nearly 2log10 CFU per 100 mg, and improved intestinal histopathology. Notably, 16S rDNA profiling showed that curcumin reversed Salmonella-driven dysbiosis by improving microbial diversity, limiting Proteobacteria/Enterobacteriaceae expansion, and enriching beneficial taxa including Lactobacillus. These compositional shifts were accompanied by recovery of key short-chain fatty acids by 40%-75% (acetate, propionate, butyrate and valerate), indicating restoration of microbiota-linked metabolic homeostasis. Collectively, curcumin mitigates pathogen-associated intestinal inflammation while rebuilding the microbiota-SCFA homeostasis supportive of mucosal barrier function, supporting its development as a food-derived functional ingredient.",

We assessed whether acSDH, compared with isolated acute SDH (aSDH), is associated with worse neurological presentation and increased radiological markers of mass effect. We conducted a retrospective multicenter cohort study using the IMADIS teleradiology head trauma workflow (103 emergency departments in France, January 2020 to December 2022). Adult patients with complicated mTBI (i.e., GCS 13-15 plus intracranial hemorrhage or skull fracture) and acute SDH on non-contrast head CT were eligible. Exposure was acSDH versus aSDH based on structured radiology reports. Outcomes were (1) GCS\u2009<\u200915 at presentation, (2) SDH maximal thickness\u2009\u2265\u20097\u00a0mm, (3) radiological brain herniation, and (4) intermediate or high QueBIC risk category. Univariable and multivariable logistic regression models were used to estimate associations. Among 935 included patients, 107 (11.4%) had acSDH. Patients with acSDH were older (\u2265\u200975 years: 57.0% vs. 39.7%, p\u2009<\u2009.0001) and more frequently had dementia (8.4% vs. 3.7%, p\u2009=\u2009.0465). Compared with aSDH, acSDH was associated with GCS\u2009<\u200915 (37.4% vs. 21.7%, P\u2009=\u2009.0010) and confusion (41.0% vs. 25.8%, p\u2009=\u2009.0016). On CT, acSDH was associated with SDH thickness\u2009\u2265\u20097\u00a0mm (54.2% vs. 20.4%, OR 4.50, 95%CI 2.90 to 7.01) and brain herniation (27.1% vs. 10.7%, OR 3.61, 95%CI 2.20 to 5.85). AcSDH was independently associated with intermediate or high QueBIC category (OR 3.38, 95%CI 1.95 to 6.27) and with the other severity markers. In complicated mTBI with acute SDH, acSDH is associated with worse neurological presentation and substantially higher radiological markers of mass effect, as well as a higher QueBIC risk category. These findings support considering acSDH as a high-risk imaging phenotype that may warrant closer early monitoring and timely neurosurgical discussion. Future studies should evaluate associations with patient-centered clinical outcomes and neurosurgical interventions. This retrospective, observational, multicenter study was approved by the French National Radiological Review Board (CRM-2507-489, on 16 July 2025).",

Lipoprotein(a) (Lp(a)) is a genetically determined vascular risk factor with pro-inflammatory and pro-atherogenic properties, but the pathways linking Lp(a) to cognitive outcomes after stroke remain unclear. We examined whether systemic inflammation mediates or modifies Lp(a)-related cognitive risk after ischemic stroke.\u00a0We analyzed data from a prespecified substudy of the Third China National Stroke Registry. Baseline serum Lp(a) and high-sensitivity C-reactive protein (hs-CRP) were measured. PSCI was defined as a Montreal Cognitive Assessment score\u2009\u2264\u200922 at 1 year. Multivariable logistic regression, interaction, joint exposure, and causal mediation analyses were performed to evaluate the role of systemic inflammation in the Lp(a)-PSCI association.\u00a0Among 954 patients with acute ischemic stroke, higher baseline Lp(a) was associated with increased PSCI risk after adjustment for baseline cognitive performance and clinical covariates (highest vs. lowest tertile: OR, 1.479; 95% CI, 1.007-2.170). In contrast, hs-CRP was not independently associated with PSCI after multivariable adjustment. No significant multiplicative interaction between Lp(a) and hs-CRP was observed (P\u2009=\u20090.2026). Although joint exposure analyses showed the highest PSCI risk among patients with both elevated Lp(a) and hs-CRP, mediation analysis did not support hs-CRP as a meaningful mediator (proportion mediated\u2009=\u20091.46%). These findings suggest that the observed association between Lp(a) and PSCI was not substantially explained by hs-CRP-indexed peripheral systemic inflammation.\u00a0Elevated Lp(a) was associated with PSCI independently of baseline cognitive performance, but this association was not mediated or significantly modified by hs-CRP. Lp(a)-related cognitive vulnerability after ischemic stroke may therefore reflect vascular susceptibility not captured by hs-CRP alone, with hs-CRP-defined systemic inflammation contributing to cumulative risk rather than serving as the primary mechanistic pathway.",

We tested whether pentoxifylline (PTX), a methylxanthine phosphodiesterase inhibitor with dual hemorheological and anti-inflammatory properties, attenuates VCI-like cognitive and inflammatory abnormalities in a rat model. Three-month-old male Sprague-Dawley rats underwent bilateral common carotid artery occlusion (BCCAO) or sham surgery. PTX (60\u00a0mg\u00a0kg\u207b1\u00a0day\u207b1, gavage) or vehicle was administered for 28\u00a0days starting 24\u00a0h post-operation. Spatial cognition was assessed with the Morris water maze; neuronal injury, microglial activation, and glucose metabolism were evaluated by histology, immunofluorescence, 1\u2078F-FDG PET/CT, and western blotting. Systemic and hippocampal cytokines were quantified by multiplex immunoassay; TLR4/MyD88/NF-\u03baB signaling was profiled by RNA-seq and western blotting. BCCAO induced progressive cognitive deficits without sustained weight loss, paralleled by CA1 neuronal damage, microglial proliferation, and marked elevations of IL-1\u03b2, IL-2, IL-17, and TNF-\u03b1 in plasma and hippocampus. PTX shortened escape latency, restored probe-trial platform crossings, preserved neuronal morphology, suppressed microglial Iba-1\u207a/Ki67\u207a expansion, and reduced all four cytokines. Mechanistically, PTX down-regulated TLR4, MyD88, and NF-\u03baB p65 mRNA and protein, reduced nuclear translocation of NF-\u03baB p65, and partially reversed frontal and hippocampal glucose hypometabolism. Peripheral IL-1\u03b2 and IL-17 levels correlated positively with cognitive impairment. Pentoxifylline concurrently mitigates hypoperfusion-associated neuroinflammation, neuronal injury, and glucose hypometabolism via inhibition of the TLR4/MyD88/NF-\u03baB axis, supporting PTX as a readily translatable candidate for early VCI intervention.",

Despite its multifactorial nature, only a few pharmacological therapies have been approved by the Food and Drug Administration (FDA), and these mainly provide symptomatic relief. Many patients experience inadequate efficacy or intolerable adverse effects, emphasizing the need for further research and improved therapeutic strategies. This review highlights contributing factors in the pathophysiology of FM, including neurochemical alterations, central sensitization, neuroinflammation, oxidative stress, mitochondrial dysfunction, gut microbiota disturbances, and autoimmunity. While some of these factors are well-established, others remain under investigation. Therapeutic strategies are discussed alongside repurposed drugs in preclinical and clinical studies, including N-methyl-D-aspartate (NMDA) receptor antagonists, neurokinin-1 receptor antagonists, drugs targeting the gamma-aminobutyric acid (GABA) system, antiepileptics, antidepressants, opioids, cannabinoids, dopamine receptor agonists, melatonin receptor agonists, and antidiabetics. Future research frontiers in FM should focus on addressing comorbidities and targeting central sensitization by enhancing descending inhibitory pain pathways, suppressing neuroinflammation through NOD-like receptor protein 3 (NLRP3) inflammasome inhibition and promotion of anti-inflammatory glial polarization besides attenuating oxidative stress and mitochondrial dysfunction. Moreover, repurposing drugs from related pain conditions such as migraine and neuropathic pain offers new therapeutic opportunities. Accordingly, this multi-target strategy may facilitate the development of effective therapies for FM.",

Human mesenchymal stem cells (hMSCs) offer multimodal neuroprotection through paracrine secretion of neurotrophic factors and immunomodulatory mediators. We reviewed preclinical and clinical evidence for hMSC therapy across multiple CA etiologies, integrating findings from neuroinflammatory, toxic/developmental, and genetic mouse models alongside published clinical trials and case reports. A systematic literature search was conducted in PubMed/MEDLINE, Embase, and the Cochrane Library (search period: 2000-2026) using the following key terms: \"mesenchymal stem cell\" AND \"cerebellar ataxia\"; \"MSC\" AND \"spinocerebellar ataxia\"; \"hMSC\" AND \"Purkinje cell\"; \"stem cell therapy\" AND \"ataxia\". Inclusion criteria encompassed: peer-reviewed original research articles and reviews in English; in\u00a0vivo animal model studies; clinical trials, case series, and case reports. Studies addressing non-CA neurological conditions without CA-relevant data were excluded. hMSC transplantation consistently improved motor function, preserved Purkinje cell integrity, and attenuated neuroinflammation across LPS-induced, Ara-C-induced, and SCA2 transgenic models. A critical observation is that MSCs from CA patients exhibit markedly reduced anti-inflammatory secretome capacity compared with healthy-donor MSCs, justifying an allogeneic strategy. Therapeutic efficacy was maintained even after symptom onset in the SCA2 model. A published case report demonstrated safety and preliminary functional benefit of intrathecal allogeneic bone marrow-derived MSCs in a sporadic adult-onset ataxia patient. hMSC therapy targets convergent CA pathomechanisms-microglial suppression, neurotrophin restoration, and Purkinje cell preservation-through a paracrine rather than cell-replacement mechanism.

Unlike prior reviews focused predominantly on aggregation as an isolated endpoint, this review proposes a neurodevelopmental-neurodegenerative continuum as an interpretive framework, suggesting that \u03b1-Syn's physiological roles in synaptic development and circuit maturation may be linked to its later pathological behaviour. Within this context, we discuss recent advances in small-molecule strategies targeting key stages of \u03b1-Syn pathology, including synthesis, misfolding, aggregation, post-translational modification, and clearance. These include translation and misfolding inhibitors, aggregation modulators such as minzasolmin (UCB0599), epigallocatechin gallate and anle138b, as well as compounds that enhance \u03b1-Syn degradation through autophagy-lysosomal and ubiquitin-proteasome pathways. Additional strategies targeting proteostasis and mitochondrial dysfunction are also considered. Beyond its pathogenic role, \u03b1-Syn contributes to synaptic vesicle trafficking, neurotransmitter release, and neuronal maturation, and disruption of these functions may increase vulnerability to later neurodegeneration. In conclusion, small-molecule-based therapies represent a promising multi-targeted strategy for PD; however, key translational challenges and unresolved questions remain, including optimisation of pharmacokinetics, target specificity, and blood-brain barrier (BBB) penetration and validation in clinical settings.",

NAD\u207a plays a central role in cellular energy metabolism, redox balance, and signaling pathways linked to aging, neurodegeneration, and metabolic health. Current evidence shows that oral NAD\u207a precursors such as nicotinamide riboside and nicotinamide mononucleotide can increase circulating NAD\u207a levels, although their clinical benefits remain variable and context-dependent. Intravenous NAD\u207a administration is less well characterized and lacks robust clinical validation. The modelling framework presented here highlights that NAD\u207a responses are nonlinear and influenced by factors such as dose, age, metabolic state, and route of administration. Rather than following a simple dose-response relationship, NAD\u207a supplementation appears to operate within a complex regulatory system involving feedback mechanisms and biological saturation. Overall, these findings emphasize the need for cautious interpretation of current data and for well-designed clinical studies to define effective and safe therapeutic strategies.",
"42489971": "ID: 42489971\nTitle: Glymphatic Dysfunction and Aquaporin-4 Dysregulation in Traumatic Brain Injury and Brain Tumors: A Review.\nAbstract: The glymphatic system is a cerebrospinal fluid-interstitial fluid exchange pathway that clears metabolic waste and maintains brain fluid homeostasis. Aquaporin-4 (AQP4), a water channel at astrocytic endfeet along the neurovascular interface, supports perivascular water transport and glymphatic flow. Disruption of this glymphatic-AQP4 unit is implicated in conditions with altered fluid dynamics, including traumatic brain injury (TBI) and brain tumors. We reviewed experimental and clinical studies examining glymphatic pathways and AQP4 regulation in TBI and brain tumors, and synthesized evidence on glymphatic physiology, AQP4 polarization, and imaging-based assessment to compare mechanisms of disruption in injury versus tumor remodeling. Evidence shows reduced glymphatic transport in both conditions, commonly accompanied by altered AQP4 localization. In TBI, mechanical injury triggers astrocytic reactivity, blood-brain barrier disruption, and loss of perivascular AQP4 polarization, impairing clearance across phases of injury. In brain tumors, parenchymal remodeling, vascular compression, and vasogenic edema disrupt cerebrospinal fluid dynamics and glymphatic pathways. Across disease states, total AQP4 expression alone poorly predicts glymphatic function; instead, spatial localization and polarization of AQP4 at astrocytic endfeet more consistently correlate with clearance efficiency. Emerging imaging approaches, including diffusion-based MRI metrics and perivascular space quantification, offer potential noninvasive methods for assessing glymphatic alterations in vivo, although their reliability and biological specificity remain debated and under active investigation. Overall, the glymphatic-AQP4 system is a key neurovascular interface regulating brain fluid balance. Disrupted AQP4 polarization and glymphatic transport contribute to edema and impaired solute clearance in both TBI and brain tumors. Future work should prioritize standardized imaging biomarkers and time-dependent strategies to restore glymphatic function and perivascular AQP4 organization.",

The basal ganglia, particularly the globus pallidus, represent a hotspot for iron deposition, yet the precise structural forms and their implications remain incompletely understood. Here, a multimodal approach was applied combining Raman microspectroscopy, light microscopy, transmission (TEM) and scanning electron microscopy coupled with energy-dispersive X-ray analysis (SEM-EDX) to characterise iron-rich deposits in post-mortem human globus pallidus. Tissue samples from six individuals without neurological disease were examined. Perls' staining revealed iron-positive, spherical inclusions 10-20\u00a0\u00b5m in diameter. Raman spectroscopy revealed bands at 268-278, 490, 526, and 603\u00a0cm-1, as well as broader signals at 1259-1349\u00a0cm-1, consistent with magnetite, maghemite, hematite, and ferritin-like structures. Additional vibrations in the 682-1532\u00a0cm-1 range indicated interactions with organic matrices, such as protein or lipid components. SEM-EDX identified both regular and irregular iron-rich particles with multielemental composition, including C, O, Al, Si, P, S, Ca, Cr, and Ni, in addition to Fe. TEM examination showed the micrometre-sized particles of hematite and aggregation of ferrihydrite. These findings suggest that iron deposits in the globus pallidus comprise heterogeneous mixtures of oxides and hydroxides with variable crystallinity. Depending on their crystallinity and surface reactivity, such phases may represent a potential pool of redox-active iron; however, the present study did not assess markers of oxidative stress, and their physiological versus pathological significance remains to be established.",

Here, we performed a comprehensive temporal characterization of the mouse hypothalamus following ovariectomy (OVX), combining physiological measurements with bulk RNA-sequencing of the posterior hypothalamus (PH) and preoptic area (POA) at short-term (14 days) and long-term (4 months) post-OVX. Serum LH levels rose progressively and then declined, while core temperature peaked early and subsequently normalized, recapitulating the endocrine and thermoregulatory dynamics of reproductive aging in humans. Transcriptomic analysis revealed time-dependent activation of inflammatory pathways, glial markers, and KNDy neuron-related gene networks, with the most pronounced changes emerging at 4 months post-OVX, particularly in the PH. Immunofluorescence confirmed increased NKB release, declining KNDy neuronal activity, and heightened astrocytic reactivity in the arcuate nucleus after prolonged estrogen withdrawal. To contextualize these findings, we analyzed publicly available human hypothalamic RNA-seq data across chronological age. Age-related transcriptomic patterns in women, including progressive inflammatory signaling, glial activation, and altered KNDy gene expression, showed significant correlation with the OVX mouse model, particularly at the pathway level. These findings establish a temporal framework for hypothalamic molecular changes after estrogen withdrawal, identify conserved neuroinflammatory signatures across species, and provide a preclinical platform for testing interventions targeting menopausal-associated hypothalamic dysfunction.",

These include metabolism, signalling, and diseases such as cancer and neurodegeneration. Despite the abundance of NADH-protein complex structures, the general principles governing how proteins shape NADH conformation and interaction modes remain unclear, limiting our ability to rationally interpret cofactor specificity, catalytic efficiency, and off-target effects of inhibitors. Here, we present a comprehensive structural analysis of NADH recognition across protein families using 345 NADH-bound crystal structures from the Protein Data Bank. We adopted a descriptor-driven strategy that quantitatively captures the internal geometry of NADH using angles, dihedrals, and interatomic distances, enabling direct comparison of cofactor shapes independent of protein fold. These studies reveal that 65% of structures preferred conformers with a conserved adenine-nicotinamide separation while allowing limited flexibility in the pyrophosphate. The interaction profiles demonstrate that NADH recognition is dominated by hydrogen bonding and electrostatic interactions involving nearly all heteroatoms, while most carbon positions remain non-interacting. Residue- and moiety-level analyses further show that the nicotinamide region serves as the primary interaction hotspot across enzyme classes, while only a handful of structures exhibit adenine-centric recognition. Together, this study establishes a unified biophysical framework that links NADH shape, interaction signatures, and protein context, providing rational insights for cofactor engineering and the design of NADH-targeted inhibitors.",

We applied GAGE-seq (genome architecture and gene expression by sequencing) to jointly profile gene expression and 3D chromatin structure in single cells from postmortem brain tissue from AD patients and age-matched individuals without AD, revealing chromatin reorganization linked to cell type-specific dysregulation. Integrations with spatial transcriptomics and chromatin accessibility data uncovered altered niches reflecting genome compartment remodeling and regulatory element reorganization. Hicformer, a deep learning framework, showed that 3D genome features are essential for predicting disease-relevant, cell type-specific gene expression changes. Our results establish higher-order chromatin alterations as a component of AD-associated molecular pathology, providing a multiscale view of transcriptional regulation and 3D genome organization in neurodegeneration.",

To unravel these complexities, we analyzed single-nucleus gene expression, chromatin accessibility, DNA methylation, and three-dimensional (3D) chromatin architecture from human hippocampal tissues spanning the adult lifespan. We identified both linear and nonlinear dynamic gene regulatory programs during aging. Between the ages of 50 to 75, embryonic yolk sac-derived microglia were depleted and replaced by cells resembling peripheral blood monocyte-derived microglia. Hippocampal astrocytes decreased substantially with age, including those regulating synaptic transmission. Across cell types, 3D genome architecture underwent global erosion. Our analysis provides insights for how altered gene regulatory programs promote cell type-specific aging phenotypes in the human brain.",

Here we describe the regenerative response in the larval zebrafish retina following ablation of cone photoreceptors. To investigate the role of microglia in the regenerative response, we used irf8st95 heterozygote (microglia-sufficient) and irf8st95 homozygous mutant (microglia-deficient) zebrafish. We compared multiple aspects of the regenerative response in irf8\u2009+\u2009/- and irf8-/- larval retinas, including entry of the M\u00fcller glia (MG) into the cell cycle, the amplification of MG-derived progenitor cell (MGPC) proliferation, inflammatory and glial reactivity-associated gene expression, and the regeneration of cones. We found only modest impacts to early and late stages of MGPC proliferation and to inflammatory gene expression in irf8 mutants, with no obvious impacts to the regeneration of cones. Notably, we detected a population of immune cells in irf8 mutants that emerged following cone ablation, which expanded in number then were reduced over time, following a trajectory similar to microglia-sufficient siblings but at markedly reduced abundance. The immune cells detected in irf8 mutants included a subset with L-plastin/4C4 antibody staining patterns different than those in microglia-sufficient siblings, suggesting distinct origins and/or phenotype compared to resident microglia in controls. The presence of immune cells in irf8 mutants following cone ablation limited our ability to make strong conclusions about the role of microglia in regeneration of cones. However, our results are consistent with several reports that indicate a role for microglia in regulating MGPC proliferation in the regenerating retina. Collectively considered with other reports, our results further indicate that compensatory responses, which may include different immune cells and/or signaling from other retinal cell types such as M\u00fcller glia, may be elicited in microglia-deficient retinas upon neuronal damage.",

Although simvastatin (SV) possesses potent pleiotropic effects in promoting BBB repair and attenuating inflammation, its clinical translation for ischemic stroke is severely hampered by poor BBB penetration, low lesion accumulation, and the need for high systemic doses that increase the risk of off-target toxicity (e.g., myopathy). To address these barriers, herein, we developed a platelet membrane-biomimetic nanoparticle system (pmPLGA@SV) designed to leverage the innate affinity of platelets for injured vasculature for lesion-targeted SV delivery at a lower effective dose. Physicochemical characterization confirmed the successful cloaking of platelet membranes onto SV-loaded PLGA cores. In vitro, pmPLGA@SV demonstrated superior therapeutic versatility: it effectively scavenged reactive oxygen species in oxygen glucose deprivation/reoxygenation-treated PC12 cells and orchestrated microglial repolarization from a pro-inflammatory M1 phenotype toward an anti-inflammatory M2 state in BV2 cells, significantly modulating the secretion of IL-1\u03b2 and IL-10. In vivo, pmPLGA@SV treatment dramatically reduced the cerebral infarct volume, exhibiting significant superiority over free SV. Furthermore, longitudinal behavioral assessments over 21 days demonstrated that pmPLGA@SV markedly accelerated motor and sensory-motor functional recovery, accompanied by consistent body weight regain and improved neurological scores. Mechanistically, pmPLGA@SV facilitates a synergistic therapeutic approach by mitigating neuronal oxidative stress and remodeling the inflammatory microenvironment. This study demonstrates that pmPLGA@SV serves as a robust biomimetic platform for the integrated treatment of neurovascular unit damage, offering a promising strategy for long-term neuroprotection and functional rehabilitation following ischemic stroke.",

The recovery after decompressive craniectomy (DC) is very heterogeneous and influenced by surgical laterality and complications. This study compared long-term outcomes after unilateral (UDC) versus bilateral DC (BDC). Patients admitted to our neurological rehabilitation center between 2000 and 2018 after BDC were matched by age, sex, and etiology to UDC. Clinical data included initial Glasgow Coma Scale, intracranial lesions, hospital admission time, complications, outcome, ventriculoperitoneal shunts and time to cranioplasty. Functional outcomes were assessed using the Extended Glasgow Outcome Scale (GOSE), Barthel Index (BI), and Early Rehabilitation Barthel Index (eBI) at discharge and follow-up. Follow-up interviews were conducted with 28 patients (15 UDC, 13 BDC) to evaluate GOSE, BI, quality of life, and home circumstances. Fifty patients (mean age 28.2 \u00b1 13\u202fyears; 28% female) were analyzed. Favorable outcomes occurred in 36% of UDC patients versus 16% of BDC patients, while unfavorable outcomes were more frequent in BDC (44% vs. 24%). UDC patients demonstrated significantly better eBI scores at discharge and follow-up (p =\u202f0.043; p =\u202f0.016) and superior GOSE outcomes (p =\u202f0.011). Shorter hospitalization correlated with favorable outcomes in UDC (p =\u202f0.012; r =\u202f-0.628). BDC patients experienced more neurological complications, which were associated with poorer outcomes (GOSE follow-up p =\u202f0.019; r =\u202f-0.411; BI follow-up p =\u202f0.022; r\u202f=\u202f0.415). BDC is associated with poorer functional outcomes and higher complication rates compared to UDC. Further randomized studies are needed to confirm these findings.",

The plasminogen system, one of the central proteolytic systems, regulates diverse physiological pathways, including fibrinolysis, inflammation, wound healing, and tissue remodelling. Beyond its proteolytic functions, the plasminogen system serves as a hub for crosstalk to maintain homeostasis. Yet, its dysregulation, misuse, or hijacking by pathogens can drive pathologies such as hereditary disorders, tumour dissemination, bacterial invasion, and viral priming. This review explores its evolution, structural aspects, activation mechanisms, regulatory pathways, and pharmacological modulation of the plasminogen system, synthesising decades of research with recent advances. We highlight the multifaceted nature of the plasminogen system-as both a guardian of physiological balance and a potential driver of disease-and discuss its components as therapeutic targets and tools.",

This review gathers current evidence that connects disruptions in microbial metabolites to the pathogenesis of neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Our comprehensive overview discusses major neuroactive metabolite classes-short-chain fatty acids (SCFAs), tryptophan derivatives, bile acids, and phenolic compounds-and their established roles functions in affecting neuroinflammation, epigenetic programming, synaptic function, and blood-brain barrier integrity. Converging evidence from human multi-omics studies and preclinical models frequently reported patterns of metabolic dysregulation in NDDs, including reduced SCFA production, altered kynurenine pathway metabolites, and accumulation of neurotoxic compounds such as para-cresol (p-cresol). However, substantial heterogeneity exists across studies, and causal evidence in humans remains predominantly associative. We further examine the critical early-life window during which the metabolite-producing microbiome is shaped by maternal factors, nutrition, and environmental exposures, with lasting consequences for neurodevelopmental trajectories. Finally, we discuss new intervention strategies such as probiotics, dietary substrates, fecal microbiota transplantation, and metabolite-based therapies, and propose a plan to transition from associative findings to causal, personalized approaches using microbial metabolites as biomarkers and therapeutic targets in child neurodevelopment.",

Electronic databases including China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, Chinese Biomedical Literature Database (CBM), PubMed, and Web of Science were searched from their inception to November 10, 2024. Literature screening, data extraction, and quality assessment were independently conducted by two researchers. The Newcastle-Ottawa Scale (NOS) was used to assess the methodological quality of the included studies. Meta-analysis was performed using RevMan 5.3 software. A total of 14 studies involving 2,729 patients with SCI were included, among whom 1,160 patients developed hyponatremia and 1,569 had normal serum sodium levels. The NOS scores of the included studies ranged from 7 to 8, indicating generally high methodological quality. Meta-analysis results showed that high-level spinal cord injury (OR\u202f=\u202f1.71, 95% CI: 1.04-2.81), complete spinal cord injury (OR\u202f=\u202f4.96, 95% CI: 3.75-6.57), concomitant traumatic brain injury (OR\u202f=\u202f2.70, 95% CI: 1.79-4.07), and the use of assisted ventilation (OR\u202f=\u202f3.28, 95% CI: 1.52-7.09) were significant risk factors for hyponatremia in patients with SCI (p <\u202f0.05). A funnel plot based on complete spinal cord injury was not completely symmetrical, suggesting a potential risk of publication bias. Current evidence indicates that high-level spinal cord injury (\u2264C4), complete spinal cord injury, concomitant craniocerebral injury, and the use of assisted ventilation are significant risk factors for hyponatremia in patients with SCI. Enhanced monitoring and management of these high-risk populations are recommended to facilitate early identification and timely intervention for hyponatremia.

We hypothesized that EGCG exerts its physiological effects via oral chemosensory signaling pathways, independent of intestinal absorption. This study utilized wild-type and Skn-1a-/- mice (lacking bitter taste signaling) to evaluate acute metabolic responses. Furthermore, a chronic study using high-fat/high-sucrose diet (HFSD)-fed rats was conducted to investigate the long-term effects of EGCG on systemic metabolism, neuroinflammation, and adipose and skeletal muscle morphology. Acute oral administration of EGCG or the bitter tastant denatonium benzoate significantly attenuated glycemic excursions and elevated plasma glucagon-like peptide-1 (GLP-1) levels in wild-type mice. Crucially, these effects were completely abolished in Skn-1a-/- mice, identifying bitter taste receptors as essential mediators. In the chronic rat model, repeated oral EGCG treatment effectively reduced food intake, body weight gain, and adiposity. Beyond metabolic regulation, EGCG suppressed Iba-1 expression in the hippocampal dentate gyrus, indicating an anti-neuroinflammatory effect. Notably, EGCG increased the cross-sectional area of both the soleus and extensor digitorum longus muscles across all diet groups, mimicking the beneficial effects of physical exercise. These findings indicate that EGCG acts as a \"metabolic trigger\" through Skn-1a-dependent chemosensory pathways, primarily involving T2R signaling. By demonstrating that bitter-related chemosensory signaling regulates systemic homeostasis and provides neuroprotective effects, this study supports a new concept of \"sensory nutrition.\" This research positions gastrointestinal and oral chemosensors as a novel and non-invasive therapeutic target for managing metabolic syndrome and cognitive decline, overcoming the limitations of systemic bioavailability.",
"42490949": "ID: 42490949\nTitle: High-altitude hypoxic cues and cerebral ischemic tolerance: an evidence-graded translational framework for stroke research.\nAbstract: High altitude exposes the brain to heterogeneous hypoxic, hemodynamic, rheological, inflammatory, and healthcare-access conditions. This heterogeneity makes altitude biologically informative for stroke research, but it does not justify treating natural altitude exposure as a single protective or harmful state. In this structured narrative review, we searched and organized the literature to ask which altitude-associated hypoxic cues resemble or reveal mechanisms compatible with cerebral ischemic tolerance, and what level of evidence supports that claim. We separate long-term adaptation, short-term acclimatization, chronic or excessive environmental hypoxia, and experimental hypoxic conditioning; define direct, supportive, and indirect evidence tiers; and integrate neurovascular-unit biology with multi-omics and stroke pathophysiology. Experimental hypoxic preconditioning remains the clearest direct evidence that a defined sublethal hypoxic stimulus can induce a time-limited tolerant state. In contrast, human high-altitude epidemiology, physiology, and genetics mainly constrain the clinical context and nominate candidate pathways rather than prove stroke-specific protection. We also emphasize that chronic hypoxia can be maladaptive through endothelial dysfunction, oxidative stress, erythrocytosis, thrombogenicity, blood-brain barrier impairment, and microvascular injury. Across neurovascular-unit cell types, a transparent evidence-weighting framework prioritizes endothelial biology because of its direct connection to BBB stability, effective reperfusion, hemorrhagic transformation risk, and no-reflow, while neurons, astrocytes, microglia, oligodendrocyte-lineage cells, and pericytes require different degrees of causal and human validation. We argue that the most productive path forward is not to label altitude as protective, but to use altitude-related biology to prioritize testable, stroke-facing hypotheses regarding BBB stability, microvascular patency, metabolic support, inflammatory thresholds, white-matter resilience, and biomarker-defined conditioning windows.",

Mild behavioral impairment (MBI) occurring in cognitively healthy individuals, however, might be significantly affected by these processes. Three hundred forty-one cognitively normal individuals were analyzed using partial least squares (PLS) regression to determine neurometabolic and brain volumetric determinants of MBI scores. Radiolabeled glucose non-displaceable binding potential and volumes of Schaefer homooxygenation parcels were screened as regressors. PLS models were evaluated with cross-validation, scrambling, and bootstrapping. Hypermetabolism in the left entorhinal cortex and hypertrophy in the left dorsal attention network B contribute substantially to the MBI total score. Significant morpho-functional interactions were observed between the right middle temporal cortex and the right salience-ventral attention B network. MBI might depend on cerebral bioenergetic processes and morpho-functional interactions. Relative hypermetabolism and hypertrophy could be considered specific biomarkers of MBI indicating a prodromal maladaptive neural response.",

Pathological angiogenesis, driven by hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1), constitutes a core pathological mechanism and has become a critical therapeutic target for RA. This article systematically elucidates the molecular mechanisms by which HIF-1\u03b1 drives pathological angiogenesis through interactions with signaling pathways such as vascular endothelial growth factor (VEGF), angiogenin (ANG)-1/2, CXC chemokine ligand 12 (CXCL12)/CXC chemokine receptor 4 (CXCR4), phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR). HIF-1\u03b1-mediated angiogenesis forms a positive feedback network with pathological processes including synovial inflammatory response, glycolytic metabolic reprogramming, and oxidative stress-mitochondrial damage, collectively promoting synovial pannus formation. Additionally, this article summarizes the effects of traditional Chinese medicine formulations and plant-derived monomeric metabolites on HIF-1\u03b1-mediated RA synovial angiogenesis, as well as the preclinical research advances of anti-angiogenic mechanisms. It also briefly explores the potential of novel botanical drugs delivery systems in enhancing the targeting of natural products to the HIF-1\u03b1 pathway and improving therapeutic efficacy, aiming to provide new perspectives and strategic options for HIF-1\u03b1-targeted RA therapies.",

A total of 113 patients were retrospectively enrolled and stratified into two groups according to hemoglobin (Hb) level: a restrictive transfusion group (Hb < 80 g/L) and an liberal transfusion group (Hb < 90 g/L). Transfusion exposure and clinical outcomes were compared between the two groups, and multivariate logistic regression as well as inverse probability of treatment weighting (IPTW) were adopted for statistical analysis. The restrictive group had lower transfusion rate and transfusion volume (both P < 0.05). The incidence of adverse neurological functional outcomes (defined as Glasgow Outcome Scale-Extended score, GOSE score \u2264 4) at 3 months postoperatively was lower in the restrictive group. Multivariate logistic regression analysis indicated that the restrictive transfusion strategy was marginally associated with a lower risk of adverse outcomes (OR=0.40, P=0.053). The IPTW analysis yielded a consistent trend without statistical significance (P=0.110). There was no statistically significant difference in the incidence of complications. The restrictive transfusion strategy can reduce transfusion exposure and is correlated with a favorable trend in neurological functional prognosis. Further studies are still required to validate these findings.",

This retrospective study included two cohorts of patients with imaging-confirmed TBI: a development cohort (n=204) and an external validation cohort (n=80). Candidate predictors included demographic characteristics, Glasgow Coma Scale score, mechanical ventilation (MV), SII, and all routine coagulation markers, including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen (FIB), and thrombin time (TT). Multivariable logistic regression was used to identify factors associated with HAP. Among patients who developed HAP, ventilator-associated pneumonia (VAP) was analyzed descriptively as an exploratory subgroup only. In the development cohort, 76 of 204 patients (37.3%) developed HAP. Patients with HAP exhibited significant coagulation abnormalities, including elevated FIB. Multivariable logistic regression with collinearity diagnostics (VIF analysis) identified SII, FIB, and MV as independent predictors. The combined model demonstrated good discrimination (AUC=0.824) and maintained moderate performance in the external validation cohort (AUC=0.675).

In recent years, epigenetic mechanisms have been widely explored as critical factors in autoreactivity. Among these modifications, N6-methyladenosine (m6A) RNA methylation stands out as a pivotal post-transcriptional regulator of immune cell function and autoimmune diseases (ADs) progression. This review outlines m6A regulation in immune microenvironments and its dual role in maintaining tolerance and promoting inflammation. This study highlights how m6A regulators, including writers (METTL3/14), erasers (FTO and ALKBH5), and readers (YTHDF1-3 and IGF2BP3), orchestrate immune cell dysfunction across systemic (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis) and organ-specific (multiple sclerosis (MS), inflammatory bowel disease (IBD), type 1 diabetes mellitus (T1DM), and autoimmune thyroid disease (AITD) ADs, revealing disease-specific epitranscriptomic regulatory patterns. Critically, we highlight recent therapeutic breakthroughs targeting m6A regulators, including METTL3 inhibition (STM2457) for Th17-driven MS and RA synovitis, ALKBH5 modulation (ALK-04) to mitigate psoriasis flares and neuroinflammation, FTO-targeting small molecules (Rhein) to prevent RA-associated bone erosion, and IGF2BP3 blockade (triptolide) to suppress RA fibroblast activity. Despite their promise, key challenges persist, including stage-specific effects (early vs. chronic), rare immune subset targeting (MDSCs in AIH), and concerns about the long-term safety of epitranscriptomic drugs. Future studies must address m6A dynamics in immune crosstalk to advance precision medicine strategies, particularly through combinatorial approaches with existing JAK inhibitors or checkpoint modulators.",

Acupuncture has shown neuroprotective effects in multiple models of neurological diseases, yet the role of HSP70 as a mechanistic link between acupuncture stimulation and neuronal protection has not been systematically clarified. To this end, current evidence on acupuncture-induced HSP70 regulation is hereby summarized, and its potential contribution to neuroprotection is accordingly discussed, with particular emphasis on mitochondrial preservation and anti-apoptotic signaling. Available studies suggest that acupuncture-associated HSP70 upregulation is linked to enhanced cellular stress adaptation, reduced oxidative injury, stabilization of Bcl-2 family-dependent mitochondrial integrity, inhibition of cytochrome c release and apoptosome formation, and suppression of downstream caspase activation. In addition to these intracellular effects, emerging evidence also uncovers the involvement of HSP70 in neuroinflammatory regulation and neuron-glia communication, suggesting its broader role in shaping the injured neural microenvironment. However, current evidence remains largely associative, leaving several key issues unresolved, including questions of causal necessity, cell-specific regulation, intercellular trafficking, and neuroimmune integration. Overall, HSP70 may represent a promising integrative mediator of acupuncture-induced neuroprotection, yet its precise mechanistic function still warrants further experimental validation.",

The development and characterization of homo- and heterotypic 3D spheroid models incorporating CCF-STTG1 astrocytes, HMC3 microglia, and U87MG glioma cells was undertaken. The assessment of morphological, molecular, and functional properties was performed via flow cytometry, cytokine arrays, ECM analysis and invasion assays (Matrigel\u2122/gelatin). Heterotypic spheroids have been observed to spontaneously self-assemble into a spatially polarized architecture, with microglia and glioma cells segregating into distinct compartments, a pattern suggestive of the cellular topology at the invasive front. The morphological, molecular, and functional properties of the generated 3D models recapitulated several established features associated with in vivo tumors, including growth, invasion, resistance to chemotherapy, and metabolic reprogramming alongside the expression of stemness markers, and key pro-invasive mediators (MMPs, SDF-1\u03b1, VEGF). Secretome profiling revealed a marked, non-additive upregulation of chemokines (IP-10, MIP-1\u03b1) and the emergence of novel correlations (HGF/SDF-1\u03b1, MCP-1/LIF), indicating potential modulation of paracrine networks involved in immune cell trafficking in the heterotypic setting. The initial formation of a rigid ECM matrix appears to be initiated by microglia, while the supply of fibronectin and laminin may be linked to astrocytes exhibiting some features of reactive gliosis, which could help organize invasion pathways. These heterotypic 3D spheroid models offer a stroma-enriched, reproducible platform for the analysis of stromal contributions to glioma progression and for exploratory preclinical evaluation of therapeutic strategies.",

Although the retrograde menstruation theory clarifies the dissemination of endometrial fragments to ectopic sites, the mechanisms behind the survival of ectopic lesions and their immune evasion in hostile microenvironments remain unclear. Endometrial stromal cells (ESCs) are chronically exposed to a microenvironment of hypoxia, nutrient deprivation and oxidative stress, and this energy stress state drives the ESCs to develop adaptive metabolic reprogramming. Through remodeling glucose, lipid, and amino acid metabolic pathways, ESCs not only fulfill their own proliferative requirements but also utilize metabolites as signaling mediators to modulate immune cell functions. This review elaborates on the characteristics of energy stress-driven metabolic reprogramming in EMs, deciphers its mechanisms underlying immune evasion, and discusses the therapeutic potential of combined metabolic-immune intervention strategies.",

In 570 participants with AD, mild cognitive impairment, or normal cognition, we combined peripheral immune profiling with multimodal magnetic resonance imaging (MRI) to evaluate glymphatic function, brain structure, and network organization. AD was characterized by reduced analysis along the perivascular space index, enlarged choroid plexus (CP) volume, increased white matter free water, reduced lymphocyte count, and elevated neutrophil-to-lymphocyte ratio (NLR). Immune indices, including NLR, platelet-to-lymphocyte ratio, systemic immune-inflammation index, and lymphocyte count, were associated with cognition and glymphatic-related MRI measures. Mediation analyses indicated that NLR influenced cognition indirectly through CP volume and downstream brain structural and network features. These findings link peripheral immune imbalance to cognitive decline through glymphatic and brain network alterations, supporting biomarker development and mechanism-guided therapeutic strategies.",

Aerobic exercise (AE) serves as a promising adjuvant intervention for diverse neuropsychiatric conditions, and accumulating evidence suggests favorable effects of AE on ASD-related behaviors and physiological traits. The bone-derived hormone undercarboxylated osteocalcin (ucOCN) induced by AE can cross the blood-brain barrier to regulate synaptic plasticity. Mendelian randomization analysis suggests an association between genetically predicted higher physical activity levels and lower ASD risk, as well as between physical inactivity and higher ASD risk. In BTBR mice (a classic ASD animal model), AE intervention was associated with improvements in ASD-like phenotypes, increased cortical ucOCN, GPR158, BDNF, and synaptic proteins, and altered MAPK/ERK/Akt2 signaling. This work provides potential mechanistic clues for AE-associated changes in synaptic plasticity, supporting non-pharmacological intervention strategies for ASD.",

High-content imaging combined a hypothesis-driven immunofluorescence (IF) panel targeting NF-\u03baB, ASC, and CD45 with a discovery-oriented cell painting (CP) assay. Phenotypes were quantified using handcrafted and representation-learning features. To classify cells, we applied Gaussian mixture models (GMMs), enabling soft probabilistic assignments that capture transitional states. Compared with graph-based methods such as Leiden, GMMs achieved similar performance while providing more interpretable descriptions of microglial heterogeneity. Deep-learning features from the targeted IF panel were most informative, yielding high classification accuracy and strong correlation with biological readouts, including NLRP3 inflammasome activation. This platform offers a scalable approach to quantify microglial states and provides a scalable platform for discovering compounds that modulate microglial phenotypes.",

Using two experimental paradigms, we confirm that a microglial deficiency exacerbates seizures and facilitates the likelihood of developing spontaneous recurrent seizures, indicating that microglia constrain seizure activity. To gain insights into microglial molecular regulators of seizure severity, we examined P2RY12 contributions and demonstrate that a loss of P2RY12 increased seizure severity in both global and microglial-specific knockout mice indicating that microglia suppress seizure severity. During seizures, P2RY12-deficient microglia displayed altered process complexity, accompanied by increased neuronal activation and reduced inhibitory tone. These results link impaired microglial responses to heightened seizure susceptibility and network excitability. Together, we establish microglia and P2RY12 signaling as protective regulators of seizure activity.",
"42491970": "ID: 42491970\nTitle: Discovery of novel indazole derivatives with anti-neuroinflammatory activity.\nAbstract: This study focuses on the critical role of microglia-mediated neuroinflammation in various neurological disorders. Utilizing the indazole heterocycle-a scaffold known for its structural plasticity and multi-target potential-as the core structure, a series of derivatives were designed and synthesized with the aim of screening and elucidating their anti-inflammatory activity and underlying mechanisms. The activities of the compounds were systematically evaluated in an in vitro LPS-stimulated BV-2 microglial model using Griess assay, MTT assay, qPCR, and western blotting. Among the 15 derivatives obtained, compound 5o exhibited the most potent anti-inflammatory activity (IC50 = 8.45 \u00b1 0.64 \u03bcM). Its mechanism of action involves the regulation of microglial polarization-significantly suppressing M1 phenotype markers such as NO, IL-1\u03b2, IL-6, TNF-\u03b1, iNOS, and COX-2. Further mechanistic studies revealed that this effect is mediated through positive regulation nuclear translocation of Nrf2. In summary, this study demonstrates that the indazole derivative 5o exerts anti-neuroinflammatory effects by inhibiting microglial M1 polarization, providing a promising lead compound and a robust pharmacological basis for the development of novel therapeutic strategies targeting neuroinflammatory diseases.",
"42492072": "ID: 42492072\nTitle: Examining Mgat5 upregulation's protective effects and underlying mechanisms in spinal cord injury.\nAbstract: Secondary inflammation severely hinders recovery after spinal cord injury (SCI). This study investigates whether boosting Mgat5-mediated N-glycosylation via a lentiviral vector can reprogram the local immune microenvironment and foster functional repair. We engineered a lentiviral vector to overexpress Mgat5 (Lv-Mgat5) and validated it in rat dorsal root ganglion cells. Next, we established a contusion SCI model in rats, dividing them into sham, SCI, MP (methylprednisolone), Lv-vector, and Lv-Mgat5 groups. Motor recovery was evaluated using BBB and inclined plane tests. To uncover the mechanisms, we quantified N-glycan branching (PHA-L precipitation), inflammatory cytokines (ELISA), and regeneration markers (Western blot). Lv-Mgat5 effectively upregulated \u03b2-1,6-GlcNAc branching both in vitro and in vivo without cytotoxicity. Importantly, this targeted intervention modulated the injured spinal cord microenvironment toward an anti-inflammatory profile. We observed a significant drop in TNF-\u03b1 and IL-1\u03b2, alongside a surge in IL-10 (p\u2009<\u20090.05). Furthermore, GAP-43 expression remained robustly elevated. Consequently, rats treated with Lv-Mgat5 showed remarkable and sustained improvements in hindlimb motor function compared to vehicle controls (p\u2009<\u20090.01). Targeted Mgat5 upregulation effectively modulates the post-injury microenvironment. By reshaping the N-glycosylation profile, it attenuates secondary neuroinflammation and supports a regeneration-associated molecular response, offering a promising target for gene therapy after SCI."
