The multifaceted mitochondrion: An attractive candidate for therapeutic strategies

Abstract

Mitochondria are considered the powerhouse of the cell and disturbances in mitochondrial functions are involved in several disorders such as neurodegeneration and mitochondrial diseases. This review summarizes pharmacological strategies that aim at modifying the number of mitochondria, their dynamics or the mitochondrial quality-control mechanisms, in several pathological instances in which any of these mechanisms are impaired or abnormal. The interplay between different cellular pathways that involve mitochondria in order to respond to stress is highlighted. Such a high mitochondrial plasticity could be exploited for new treatments.

Keywords: Mitochondrial biogenesis; Mitochondrial plasticity; Mitochondrial quality control.
