摘要
线粒体相关内质网膜(mitochondria-associated endoplasmic reticulum membranes,MAM)是内质网(endoplasmic reticulum,ER)膜与线粒体外膜紧密连接的特化部分,构成ER和线粒体之间通讯的物理基础,并在Ca~(2+)稳态、氧化应激、炎症、线粒体形态功能调控、脂质代谢、细胞凋亡、自噬等过程中发挥重要作用。深入研究发现,MAM功能与缺血性脑卒中病理生理机制高度相关。另一方面,多种具有明确抗缺血性脑卒中作用的药物或化合物通过影响MAM相关蛋白发挥作用。该文就MAM在缺血性脑卒中病理进程中的作用,以及其作为抗缺血性脑卒中的潜在药物靶点作一综述。
Mitochondria-associated endoplasmic reticulum membranes( MAM) provide an excellent scaffold for crosstalk between ER and mitochondria,which play an important role in Ca~(2+) homeostasis,oxidative stress,inflammation,mitochondrial morphological and functional regulation,lipid metabolism,apoptosis,autophagy and other processes. With the in-depth research,the function of MAM and the pathophysiological mechanisms of ischemic stroke overlap highly. On the other hand,a variety of drugs or compounds protect against ischemic stroke by affecting MAM-related proteins. In this review,we summarize the critical role of MAM in ischemic stroke and the potential of MAM as one drug target for treating ischemic stroke.
