Molecular Mechanisms Underlying the Role of Mitophagy in Neurodegeneration

Abstract

Mitophagy is a selective autophagy process in which damaged or surplus mitochondria are removed to sustain normal homeostasis. The efficient removal of damaged or stressed mitochondria is crucial for cellular health. Recent literature emphasizes the role of PINK1-Parkin pathways in the pathogenesis process of various neurodegenerative disorders. Further, mitophagy has shown potential therapeutic activity in treating neurodegenerative diseases. Thus, mitophagy might be important in the field of pharmacotherapeutics. In the present chapter, the authors explain mitophagy, mitophagy signaling pathways, as well as mechanisms and roles of mitophagy in various neurodegenerative disorders.
