Abstract: Intestinal ischemia/reperfusion injury (II/RI) is a common pathological process in clinical practice. Ischemia/reperfusion causes damage to intestinal mucosa and distant organs, and induces systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS). Autophagy is a defense regulation mechanism under stress conditions, which can maintain the homeostasis of cytoplasm, proteins and organelles. The mechanism of autophagy is complex, which is co-regulated by protein complexes encoded by evolutionarily conserved autophagy-related gene (ATG) and a variety of signaling molecules and pathways. Studies have found that autophagy is involved in the process of intestinal ischemia-reperfusion injury. Therefore, revealing the mechanism of autophagy in II/RI can provide evidence for the prevention and treatment of II/RI.
