A schematic illustration of mitochondrial quality control in Parkinson's disease. (a) Mitochondrial biosynthesis plays an important role in mitochondrial quality control by creating new mitochondria to replace damaged mitochondria. (b) Mitochondrial dynamics include both mitochondrial division and mitochondrial fusion, which are critical for maintaining mitochondrial homeostasis and normal function. (c) Autophagy is generally a process by which cells degrade harmful or excessive cellular components and thus recycling components to maintain the homeostasis.
