Alcohol abuse triggers neuroinflammation, leading to neuronal damage and further memory cognitive impairment. Few satisfactory advances have been made in the management of alcoholic central nervous Therefore, novel more practical treatment options are urgently needed. Butyrate, a crucial metabolite short-chain fatty acids (SCFAs), has increasingly demonstrated protect against numerous metabolic diseases. However, impact butyrate on chronic alcohol consumption-induced system (CNS) lesions remains unknown.In this study, we assessed possible effects underlying mechanisms attenuation alcohol-induced CNS injury mice. Firstly, sixty female C57BL/6 J mice were randomly divided into 4 groups: pair-fed (PF) group (PF/CON), alcohol-fed (AF) (AF/CON), PF with sodium (NaB) (PF/NaB) AF NaB (AF/NaB). Each was fed modified Lieber-DeCarli liquid diet or without alcohol. After six weeks feeding, euthanized associated indicators investigated.As indicated by behavioral tests brain morphology, dietary administration significantly ameliorated aberrant behaviors, including locomotor hypoactivity, anxiety disorder, depressive behavior, impaired learning, spatial recognition memory, effectively reduced damage. To understand mechanisms, microglia-mediated inflammation M1/M2 polarization measured separately. pro-inflammatory TNF-α, IL-1β, IL-6 peripheral blood circulation decreased, but IL-10 increased AF/NaB compared AF/CON group. Consistently, abnormal proportions activated resting microglial cells hippocampus cortex regions after excessive consumption treatment. Moreover, rectification microglia (M1/M2) imbalance found via binding GPR109A, up-regulating expression PPAR-γ down-regulating TLR4/NF-κB activation. In addition direct suppression intriguingly, intervention remarkably levels intestinal tight junction protein occludin gut morphological barrier, attenuated serum lipopolysaccharide (LPS) dysbiosis microbiota, suggesting that supplementation improved integrity permeability microecology. Finally, neurotransmitters differential Tryptophan (Trp) Kynurenine (Kyn) administration, which showed altered closely correlated microbiota composition, demonstrating complex interactions microbiome-gut-brain axis involved efficacy therapy for lesions.Dietary microbial ameliorates improves related functions through suppressing neuroinflammation GPR109A/PPAR-γ/TLR4-NF-κB signaling pathway modulating microbiota-gut-brain axis.

The human body is full of an extensive number commensal microbes, consisting bacteria, viruses, and fungi, collectively termed the microbiome. initial acquisition microbiota occurs from both external maternal environments, vast majority them colonize gastrointestinal tract (GIT). These microbial communities play a central role in maturation development immune system, nervous GIT system are also responsible for essential metabolic pathways. Various factors, including host genetic predisposition, environmental lifestyle, diet, antibiotic or nonantibiotic drug use, etc., affect composition gut microbiota. Recent publications have highlighted that imbalance microflora, known as dysbiosis, associated with onset progression neurological disorders. Moreover, characterization microbiome-host cross talk pathways provides insight into novel therapeutic strategies. Novel preclinical clinical research on interventions related to microbiome treating conditions, autism spectrum disorders, Parkinson's disease, schizophrenia, multiple sclerosis, Alzheimer's epilepsy, stroke, hold significant promise.

Depression is the most common mental disorder and a leading cause of disability worldwide. Despite abundant research, precise mechanisms underlying pathophysiology depression remain elusive. Accumulating evidence from preclinical clinical studies suggests that alterations in gut microbiota, microbe-derived short-chain fatty acids, D-amino acids metabolites play key role via brain–gut–microbiota axis, including neural immune systems. Notably, axis might crucial susceptibility versus resilience rodents exposed to stress. Vagotomy reported block depression-like phenotypes after fecal microbiota transplantation "depression-related" microbiome, suggesting vagus nerve influences through axis. In this article, we review recent findings regarding discuss its potential as therapeutic target for depression.

Previous studies have identified a crucial role of the gut microbiome in modifying Alzheimer’s disease (AD) progression. However, mechanisms microbiome–brain interaction AD were so far unknown. Here, we identify microbiota-derived short chain fatty acids (SCFA) as microbial metabolites which promote Aβ deposition. Germ-free (GF) mice exhibit substantially reduced plaque load and markedly SCFA plasma concentrations; conversely, supplementation to GF increased levels conventionally colonized (specific pathogen-free [SPF]) animals SPF even further exacerbated load. This was accompanied by pronounced alterations microglial transcriptomic profile, including upregulation ApoE. Despite recruitment plaques upon supplementation, microglia contained less intracellular Aβ. Taken together, our results demonstrate that are critical mediators along gut-brain axis deposition likely via modulation phenotype.
