LRRK2 Mediates α-Synuclein-Induced Neuroinflammation and Ferroptosis through the p62-Keap1-Nrf2 Pathway in Parkinson's Disease.

ABSTRACT: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide, characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta and the abnormal aggregation of α-synuclein (α-syn). Despite extensive research, the mechanisms underlying microglial-mediated neuroinflammation and ferroptosis in PD remain inadequately understood. In particular, the role of leucine-rich repeat kinase 2 (LRRK2) in microglial cells and its modulation of the p62-Keap1-Nrf2 signaling pathway warrant further investigation.In this study, we present novel findings demonstrating that LRRK2 regulates microglial neuroinflammation and ferroptosis through the p62-Keap1-Nrf2 signaling axis in the context of PD.
