摘要
This open question research article highlights mitochondria-associated endoplasmic reticulum (ER) membranes (MAMs), which have emerged as crucial cellular structures that challenge our traditional understanding of organelle function. This review highlights the critical importance of MAMs as a frontier in cell biology with far-reaching implications for health, disease and ageing. MAMs serve as dynamic communication hubs between the ER and mitochondria, orchestrating essential processes such as calcium signalling, lipid metabolism and cellular stress responses. Recent research has implicated MAM dysfunction in a wide array of conditions, including neurodegenerative diseases, metabolic disorders, cardiovascular diseases and cancer. The significant lack of biological knowledge behind MAM function emphasizes the need to study these enigmatic subcellular sites in greater detail. Key open questions include the mechanisms controlling MAM formation and disassembly, the full complement of MAM-associated proteins and how MAMs contribute to cellular decision-making and ageing processes. Advancing our understanding of MAMs through interdisciplinary approaches and cutting-edge technologies promises to reveal new insights into fundamental cellular signalling pathways and potentially lead to innovative therapeutic strategies for a range of diseases. As such, MAM research represents a critical open question in biology with the potential to transform our understanding of cellular life and human health.
