【Background and Objective】
1-Methy-4-phenylpyridiniumion (MPP+), the active metabolite of MPTP, is selectively accumulated in the mitochondria of dopaminergic neurons and confers toxicity and neuronal death through inhibiting complex I of the mitochondrial electron transport chain. Inhibition of complex I by MPP+ caused the disintegration of oxidative phosphorylation and Ca2+ influx,resulting in nNOS excess activation and NO overproduction. In addition, mitochondria also produce large amounts ...
