Modulation of Mitochondrial Dynamics by the Angiotensin System in Dopaminergic Neurons and Microglia.

ABSTRACT: Renin-angiotensin system (RAS) dysfunctions have been associated to life-spam, and aging-related diseases, including neurodegenerative diseases, such as Parkinson's disease, and the neuroinflammatory associated processes. Mitochondrial dysfunctions play a major role in aging-related diseases, including dopaminergic neurodegeneration and neuroinflammation. However, the mechanisms of RAS/mitochondria interactions remain to be clarified. In the present work, we studied the role of major RAS components in the mitochondrial dynamics in dopaminergic neurons and microglia using in vitro and in vivo models. In dopaminergic neurons, we observed that activation of the RAS pro-oxidative/pro-inflammatory axis (Angiotensin II/Angiotensin type-1 receptor, AT1/NADPH oxidase complex) produces a dysregulat
