ABSTRACT The commensal bacterium Alistipes shahii is a core microbe of the human gut microbiome and its abundance negatively correlated with inflammatory bowel diseases (IBDs). However, fundamental role in regulating response remains unknown. Using dextran sulfate sodium (DSS)-induced colitis mouse model, we examined effect A. strain As360 intervention on host found that alleviated disease activity index, colon shortening, colonic histopathological lesion. levels tight junction proteins (mainly ZO1 claudin-1) were decreased DSS-induced mice, whereas these elevated mice treatment. In addition, treatment led to alterations cytokine release, especially an increase IL10. It also reduced expressions mtor Nlrp3 increased expression mTOR inhibitor Ddit4 at transcriptional level. 16S rRNA amplicon sequencing Bacteroides , producer short-chain fatty acids (SCFAs), was enriched fecal samples Metabolic analyses that, following treatment, SCFAs content lactic acid cecal content. These findings suggest supplementation promising strategy prevent colitis. IMPORTANCE As one microbes keystone species gut, has potential inhibit inflammation improve (IBDs) conditions. this study, experimentally demonstrated oral administration symptoms colitis, altered release cellular factors, intestinal epithelial barrier damage, changed microbiota metabolites. provide deeper understanding beneficial effects perspective for better strategies IBD.

The human gut microbiome contains the largest number of bacteria in body and has potential to greatly influence metabolism, not only locally but also systemically. There is an established link between a healthy, balanced, diverse overall health. When becomes unbalanced (dysbiosis) through dietary changes, medication use, lifestyle choices, environmental factors, ageing, this profound effect on our health linked many diseases, including metabolic inflammatory neurological diseases.

The pathogenic mechanisms underlying distal symmetric polyneuropathy (DSPN), a common neuropathy in patients with diabetes mellitus (DM), are not fully understood. Here, we discover that the gut microbiota from DSPN can induce phenotype exhibiting more severe peripheral db/db mice. In randomized, double-blind, and placebo-controlled trial (ChiCTR1800017257), compared to 10 who received placebo, was significantly alleviated 22 fecal transplants healthy donors, independent of glycemic control. bacterial genomes correlated Toronto Clinical Scoring System (TCSS) score were organized two competing guilds.

Abstract The epithelial barrier theory links the recent rise in chronic non-communicable diseases, notably autoimmune and allergic disorders, to environmental agents disrupting barrier. Global pollution toxic agent exposure have worsened over six decades because of uncontrolled growth, modernization, industrialization, affecting human health. Introducing new chemicals without any reasonable control their health effects through these years has led documented adverse effects, especially on skin mucosal barriers. These substances, such as particulate matter, detergents, surfactants, food emulsifiers, micro- nano-plastics, diesel exhaust, cigarette smoke, ozone, been shown compromise integrity. This disruption is linked opening tight-junction barriers, inflammation, cell death, oxidative stress, metabolic regulation.
