Excessive alcohol consumption increases the severity and worsens outcomes of pulmonary infections, often due to oxidative stress tissue damage. While mechanism behind this relationship is multifaceted, recent evidence suggests ethanol-induced changes gut microbiome impact gut–lung axis. To assess this, a chronic–binge ethanol feeding mouse model was used determine how altered microbiome, small intestinal epithelial barrier, immune responses, as well neutrophil abundance in lungs, supporting health with tributyrin supplementation during exposure affected these responses. We found that bacterial taxa metabolic processes, distorted induced both bacteria endotoxin translocation into lymphatic circulatory systems. These were associated increased (Ly6G) presence markers stress, lipocalin-2 myeloperoxidase, lungs. Importantly, rescued function (p < 0.05), barrier integrity, reducing Ly6G mRNA 0.05) 0.01) data suggest ethanol-associated disruption homeostasis influenced therapeutics may also support lung health.

Alcohol use disorder (AUD) affects millions of people worldwide and can lead to deleterious physical social consequences. Recent research has highlighted not only the effect alcohol on gut microbiome, but also role microbiome gut-brain axis in development maintenance disorder. This review provides an overview reciprocal relationship between consumption including effects microbial composition, changes metabolites response consumption, how may modulate behavior. We discuss gut-mediated mechanisms neuroinflammation that contribute result from AUD, disruption intestinal barrier, toll-like receptor signaling, activation glial cells immune cells. Finally, we current evidence microbial-directed therapies for AUD implications this our understanding pathophysiology future directions.

Background Endocannabinoids acting via cannabinoid receptor 1 (CB1R) can elicit increased intestinal permeability (a condition also called ‘leaky gut’). Alcohol binge adversely affect digestive functions, including permeability; however, the underlying mechanisms remain incompletely understood. The current study aimed at examining whether CB1R is involved in alcohol binge-induced permeability. Methods We developed epithelial-specific knockout (CB1 IEC−/− ) mice and evaluated vivo contribution of gut Results anandamide levels proximal small intestine association with Radioligand binding functional assays confirmed that genetic deletion epithelial did not alter density or functionality brain. Additionally, a peripheral antagonist, ( S )-MRI-1891 (INV-202/monlunabant), exhibited comparable affinity to brain homogenates. An acute oral administration (3 mg/kg) reduced littermate control CB1 f/f floxed/floxed) but had no effect mice, underscoring role this phenomenon. Mechanistically, we found activated CB1R-ERK1/2 pathway subsequent downregulation tight junction proteins reduction villi length. In addition, targeting downstream ERK1/2 was able reverse process, upregulation length, thus improving barrier function. Despite effects on permeability, significantly metabolic parameters liver disease. Conclusion Our findings suggest promotes leaky activation demonstrate inhibition peripheral-restricted selective antagonists prevent

Abstract Background and aims Alcohol remains a global risk factor for non-communicable diseases with the gut microbiome emerging as novel elucidator. We investigated how associates alcohol on population level, if there is mediation reflected in health outcomes, functional potential related. Methods Our sample consisted of 4575 shallow-shotgun sequenced fecal samples from FINRISK 2002 cohort (25-74yrs., 52.5% women). (g 100% alcohol/week) use was self-reported. Diversity differential species abundances were analyzed using multiple linear regression. Compositional differences PERMANOVA, prospective associations Cox-regression. Connections between alcohol, microbiome, inflammatory markers, outcomes assessed serial mediation. Functional KEGG-orthologies Results High-risk consumers had significantly lower bacterial diversity when compared to low-risk (mean±SD:4.04±0.41 vs. 4.11±0.43, p = 9.56 × 10 − 4 ). also associated significant shifts overall composition (PERMANOVA; ≤ 1.00 ) 344 (ANCOM-BC2; q 0.05). These characterized by an increase relative Gram-negative bacteria, top genera which Bacteroides Prevotella , decrease putatively beneficial such Lactobacillus Bifidobacterium Akkermansia . Prospective all-cause mortality (HR:1.12 [1.02—1.23]), liver disease (HR:1.53 [1.22—1.92]) observed. The association mediating link via proinflammatory beta-diversity principal coordinate (OR:1.04 [1.001—1.10]). observed 1643 KO-groups (q < 0.05, n positive =431, negative =1212). Antioxidative integrity maintaining functions diminished lipopolysaccharide synthesis enriched. Conclusions community-level towards enriched levels bacteria. profile that mediates alcohol’s effect incident risk, possibly increased proliferation endotoxins through epithelial lining.

Non-alcoholic fatty liver disease (NAFLD) is an umbrella term that encompasses a diverse range of clinicopathological findings largely unknown etiology. It refers to conditions characterized by steatosis in more than 5% hepatocytes, often associated with metabolic risk factors such as obesity and type 2 diabetes. fat accumulation cells, including simple (non-alcoholic liver, NAFL), non-alcoholic steatohepatitis (NASH), NASH-associated fibrosis, cirrhosis, hepatocellular carcinoma (HCC), all which occur without significant alcohol intake or other chronic disorders. Pathohistologically, NAFLD defined mild inflammation (NAFL) necroinflammatory subtype injury, hepatocyte ballooning. Affecting approximately one-quarter the global adult population, poses health economic burden on societies, yet no definitive approved pharmacotherapies currently exist. Often asymptomatic, frequently identified incidentally during investigations for issues. A hallmark this condition lipid droplets contain triglycerides, cholesterol esters, species. To better reflect its metabolism-related etiology, recent consensus has proposed renaming dysfunction-associated (MAFLD). This chapter aims educate general public about NAFLD, providing overview establishes foundation understanding subsequent chapters book.

Early initiation of alcohol use during adolescence, and adolescent binge drinking are risk factors for the development disorder later in life. Adolescence is a time rapid sex-dependent neural, physiological, behavioral changes as well period heightened vulnerability to many effects alcohol. The goal present studies was determine age-related blood (leukocyte populations) body composition across adolescence early adulthood, investigate whether intermittent ethanol (AIE) exposure would alter trajectory on these broad physiological parameters. We observed significant ontogenetic leukocyte populations that were mirrored by an increase cytokine expression among mixed circulating leukocytes. Despite developmental changes, AIE did not significantly overall numbers or gene expression. However, led sex-specific fat mass percentage, with AIE-exposed male rats showing decreased levels female increased relative controls. These suggest while may levels, more complex phenotypic could underlie previously reported differences Coupled long-term shifts adipocyte this have long-lasting innate immunity capacity individuals respond immunological threats.
