Abstract
En 中文
Aging is a natural process leading to the slow and progressive deterioration of numerous physiological functions. It is the main risk factor for several neurodegenerative diseases. Mitochondriaassociated membranes (MAMs) or mitochondria-ER contacts (MERCs) are essential and dynamic sites of contact between mitochondria and the endoplasmic reticulum (ER) and are involved in numerous cellular processes, such as calcium (Ca2+) homeostasis, reactive oxygen species (ROS) production, autophagy, inflammation, mitochondrial dynamics, apoptosis, lipid biosynthesis, and trafficking. As a result, they play a significant role in maintaining cellular functionality regulating metabolism and ensuring proper stress responses. Recently, MAMs have been widely investigated to understand their critical role in cell physiology as well as in different pathological conditions. Increasing evidence indicates that alterations in ER-mitochondria communication contribute to aging and the development of age-related diseases. However, the cellular mechanisms underlying this link remain unclear. Understanding how these interactions change with age could provide further insights into the aging process and the mechanisms underlying age-related diseases, suggesting potential new therapeutic strategies. This review summarizes the current knowledge on MAM biology, focusing on their role in the pathogenesis of age-related brain disorders. Their therapeutic potential in limiting the progression of some neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis, and slowing the physiological aging process are also explored.
