Abstract
“Mitochondria play central roles in cellular metabolism and in key processes such as inflammation, stress response, cell death and signalling. Mitochondrial quality control (MQC) mechanisms continuously monitor organelle integrity and function, and repair or eliminate damaged mitochondria to replace them with newly formed, healthy organelles. MQC is particularly important under metabolic or environmental stress conditions. Failure of MQC paves the way to chronic diseases, such as diabetes, metabolic syndromes and immunosenescence. This Review summarizes our current understanding of MQC biology in the context of healthy human longevity. We explore the regulation of MQC in physiological conditions and explain how the dysregulation of MQC in ageing negatively impacts systemic metabolism and immune function. We discuss emerging therapeutic strategies—such as NAD+, AMPK activators and caloric restriction—that maintain a robust MQC to improve metabolic resilience and illustrate how preclinical and clinical studies can leverage MQC as a potential gerotherapeutic target.”
