In recent years, the study of endoplasmic reticulum stress involved in the pathogenesis of inflammatory bowel disease in animals has caused wide attention, unfolded or misfolded proteins accumulate in the lumen of the endoplasmic reticulum and cause endoplasmic reticulum stress, persistent endoplasmic reticulum stress can lead to intestinal mucosal barrier damage and induce intestinal inflammation. This paper reviewed the endoplasmic reticulum stress relieving mechanism, unfolded protein response and interaction mechanism of endoplasmic reticulum stress with intestinal inflammation, aimd to pr...
