- Abstract
Parkinson's disease (PD) is a progressive neurodegenerative disease with no known cure and affects approximately 1% of the elderly population. The major question in PD relates to the selective loss of dopaminergic neurons in patients. The underlying mechanism of genetic dysfunction and environmental toxins in contributing to the pathogenesis of PD may be oxidative stress. The interactions of genetic and environmental factors in PD may provide some answers to the longstanding question. In particular, the possibility that iron may provide selectivity to genetic susceptibility or dopamine reactivity in dopaminergic neuronal death is enhanced by the neuroprotection demonstrated in transgenic mice overexpressing ferritin or the use of iron chelators in MPTP-induced PD mouse. It will be important to dissect and understand the contributions of genes, environment and intrinsic cellular states in the generation and progression of the pathophysiology of PD.
