Parkinson’s disease(PD) is a chronic,progressive neurodegenerative central nervous system disease which occurs in the substantia nigra-corpus striatum system.The main pathological feature of PD is selective dopaminergic neuronal loss with distinctive Lewy bodies in populations of surviving dopaminergic neurons.In the clinical and neuropathological diagnosis of PD,brain-derived neurotrophic factor mRNA expression in the substantia nigra pars compacta is reduced by 70%,and surviving dopaminergic neurons in the PD substantia nigra pars compacta express less brain-derived neurotrophic factor(BDNF) mRNA(20%) than their normal counterparts.In recent years,knowledge surrounding the relationship between neurotrophic factors and PD has increased,and detailed pathogenesis of the role of neurotrophic factors in PD becomes more important.
