Abstract (original English)

Mitochondria are central to cellular energy metabolism and play a key role in regulating important physiological processes, including apoptosis and oxidative stress. Mitochondrial quality control has recently garnered significant attention, with the underlying mechanisms traditionally considered to be mitophagy and its dynamics. Various studies have demonstrated that extracellular vesicles are crucial for the transmission of mitochondria and their components. These vesicles effectively transport mitochondria to target cells, facilitating intercellular material exchange and signal transmission, thereby enhancing cellular function and viability. This review explores the mechanisms of mitochondrial transfer through mitochondrial extracellular vesicles (MitoEVs), analyzes the novel roles of MitoEVs in mitochondrial quality control, and discusses their applications in disease treatment. We aim to provide new perspectives for future research and support the development of relevant therapeutic strategies.
