摘要
缺血性脑卒中是一种严重的脑血管疾病,具有高发病率、高致残率和高死亡率的特点.自噬是指细胞利用溶酶体降解受损细胞器和大分子物质的过程.缺血后脑内自噬被激活,然而自噬在缺血性脑卒中过程中的作用尚存争议.近年来,越来越多的证据提示自噬通过多种机制减缓了缺血性脑卒中损伤.本文回顾了缺血性脑卒中诱导自噬的主要病理因素,探讨了自噬在缺血脑内的作用及其机制,总结了缺血性脑卒中过程中自噬的调节剂,以期更新对缺血性脑损伤过程中自噬作用及其机制的认识,为相关抗缺血性脑卒中药物的研究提供新的思路.
Ischemic stroke is a severe cerebrovascular disease that is associated with high morbidity, disability, and mortality. Ischemia activates neuronal autophagy;however, the contribution of autophagy in ischemic brains remains controversial. Autophagy is an intracellular process by which cells degrade damaged organelles and macromolecules via lysosomal pathways. Emerging evidence suggests that autophagy ameliorates ischemic stroke through a variety of mechanisms. Here, we summarize the pathological events that may trigger autophagy in ischemic brains and discuss how autophagy may impact the process of ischemic stroke. We also review the regulatory mechanisms of autophagy in the process of cerebral ischemia and summarize the bioactive compounds that are known to regulate autophagy in ischemic brains. We aim to update the knowledge regarding autophagy in cerebral ischemia and provide new insights into novel drugs for stroke therapy.
