Oxidative stress in Parkinson's disease.

@article{citeulike:566567, abstract = {Oxidative stress contributes to the cascade leading to dopamine cell degeneration in Parkinson's disease (PD).

Oxidative damage to lipids, proteins, and DNA occurs in PD, and toxic products of oxidative damage, such as 4-hydroxynonenal (HNE), can react with proteins to impair cell viability.
