Manganese toxicity is associated with mitochondrial dysfunction and DNA fragmentation in rat primary striatal neurons.

Abstract

Manganese (Mn) in excess is toxic to neurons of the globus pallidus, leading to a Parkinsonian-like syndrome. We used rat primary neuron cultures to examine the cellular events following manganese exposure. Following exposure to Mn(2+) for 48 h, striatal neurons showed dose-dependent losses of mitochondrial membrane potential and complex II activity. The Mn… (More)
