Nigral cell death in Parkinson's disease (PD) may involve oxidative stress and mitochondrial dysfunction initiated by a decrease in reduced glutathione (GSH) levels in substantia nigra. L-buthionine-(S,R)-sulphoximine (BSO; 4.8 and 9.6 mg/kg/day), an irreversible inhibitor of gamma-glutamyl cysteine synthetase, was chronically infused into the left lateral(More)
The cause of neuronal loss in patients with idiopathic Parkinson's disease is unknown. Oxidative stress and complex I deficiency have both been identified in the substantia nigra in Parkinson's disease but their place in the sequence of events resulting in dopaminergic cell death is uncertain. We have analysed respiratory chain activity, iron and reduced(More)
