The systemic rotenone model of Parkinson's disease (PD) accurately replicates many aspects of the pathology of human PD and has provided insights into the pathogenesis of PD. The major limitation of the rotenone model has been its variability, both in terms of the percentage of animals that develop a clear-cut nigrostriatal lesion and the extent of that(More)
More than 80 years after iron accumulation was initially described in the substantia nigra (SN) of Parkinson's disease (PD) patients, the mechanisms responsible for this phenomenon are still unknown. Similarly, how iron is delivered to its major recipients in the cell - mitochondria and the respiratory complexes - has yet to be elucidated. Here, we report a(More)
Cysteine residues in proteins have important biological roles. For example, disulfide bonds are important structural elements; additionally, reversible oxidation of thiols to disulfides functions as a molecular switch and constitutes an early response to oxidative damage. Because organs are heterogeneous structures composed of diverse cell types, there is a(More)
