The neurotoxin MPTP reproduces most of the biochemical and pathological hallmarks of Parkinson's disease. In addition to reactive oxygen species (ROS) generated as a consequence of mitochondrial(More)
Striatal neurons which are immunoreactive (ir) to aromatic L-amino-acid decarboxylase (AADC) or tyrosine hydrodroxylase (TH) may play a role in the decarboxylation of L-DOPA to dopamine (DA) in(More)
It has recently been shown that the dopaminergic cell loss induced by neurotoxins is enhanced by brain angiotensin II (AII) via type 1 receptors (AT1). However, the mechanisms involved in the(More)
An age-related proinflammatory, pro-oxidant state in the nigra may increase the vulnerability of dopaminergic neurons to additional damage. Angiotensin II, via type 1 (AT1) receptors, is one of the(More)
Cell death induced by 6-hydroxydopamine (6-OHDA) is thought to be caused by reactive oxygen species (ROS) derived from 6-OHDA autooxidation and by a possible direct effect of 6-OHDA on the(More)
