摘要The intestinal tract,a complex organ responsible for nutrient absorption and digestion,relies heavily on a balanced gut microbiome to maintain its integrity.Disruptions to this delicate microbial ecosystem can lead to intestinal inflam-mation,a hallmark of inflammatory bowel disease(IBD).While the role of the gut microbiome in IBD is increasingly recognized,the underlying mechanisms,particularly those involving endoplasmic reticulum(ER)stress,autophagy,and cell death,remain incompletely understood.ER stress,a cellular response to various stressors,can trigger inflam-mation and cell death.Autophagy,a cellular degradation process,can either alleviate or exacerbate ER stress-induced inflammation,depending on the specific context.The gut microbiome can influence both ER stress and autophagy pathways,further complicating the interplay between these processes.This review delves into the intricate relation-ship between ER stress,autophagy,and the gut microbiome in the context of intestinal inflammation.By exploring the molecular mechanisms underlying these interactions,we aim to provide a comprehensive theoretical framework for developing novel therapeutic strategies for IBD.A deeper understanding of the ER stress-autophagy axis,the gut microbial-ER stress axis,and the gut microbial-autophagy axis may pave the way for targeted interventions to restore intestinal health and mitigate the impact of IBD.
