[Mitochondrial dysfunction and oxidative damages in the molecular pathology of Parkinson's disease].

Parkinson's disease is a complex disease characterized by a progressive degeneration of nigrostriatal dopaminergic neurons. Development of this condition is defined by interaction between the genetic constitution of an organism and environmental factors. The analysis of the genes associated with development of monogenic forms of disease, has allowed pointing out proteasome degradation, the differentiation of dopaminergic neurons, the mitochondrial dysfunction and oxidative damage. In this review a variety of data which indicate on a key role of the mitochondrial dysfunction and oxidative stress in Parkinson's disease pathogenesis will be more detail considered.
