Abstract

Manganese (Mn), the third most abundant transition metal in the earth's crust, has widespread applications in the emerging field of organometallic catalysis and traditional industries. Excessive Mn exposure causes neurological syndrome resembling Parkinson's disease (PD). The pathogenesis of PD is thought to involve microglia-mediated neuroinflammatory injury, with mitochondrial dysfunction playing a role in aberrant microglial activation. In the early stages of PD, PINK1/Parkin-mediated mitophagy contributes to the microglial inflammatory response via the cGAS/STING signaling pathway. Suppression of PINK1/Parkin-mediated mitophagy due to excessive Mn exposure exacerbates neuronal injury. Moreover, excessive…
