    摘要:

    线粒体-内质网结构偶联(mitochondria-associated membranes,MAMs)是线粒体外膜和内质网膜之间进行通讯交流及物质交换的特殊结构域,执行不同条件下细胞生命活动的多种生物学过程。 MAMs 功能障碍介导的 Ca2+稳态失衡、内质网应激、线粒体自噬缺陷、线粒体分裂-融合平衡障碍、脂质代谢紊乱、炎症反应是阿尔茨海默病(Alzheimer’s disease,AD)关键的发病机制。 本文围绕 MAMs 结构与功能、参与 AD 病理环节、药物干预靶点等方面进行综述,探讨 MAMs 在 AD 发病中的作用及最新机制研究进展,以期为 AD 的防治提供新思路。

    Abstract:

    Mitochondria-associated membranes ( MAMs ) are a subcellular compartment involved in the communication and material exchange between the mitochondrial outer membrane and endoplasmic reticulum membrane.MAMs perform various biological processes in cells under different conditions. MAM-dysfunction-mediated calcium homeostasis imbalance, endoplasmic reticulum stress, mitophagy defects, mitochondrial fission / fusion dynamics imbalance, lipid metabolism disorders, and inflammatory responses are key pathogenic factors in Alzheimer’ s disease (AD). This article reviews the structure and function of MAMs, their involvement in AD pathology, and drug intervention targets, and discusses the role of MAMs in the pathogenesis of AD and the latest research into their mechanisms, to provide new ideas for the prevention and treatment of AD.
