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.
