Abstract

Using highly sensitive sandwich enzyme-linked immunosorbent assays (ELISA), we measured for the first time the concentrations of brain-derived growth factor (BDNF) in the brain (substantia nigra, caudate nucleus, putamen, cerebellum, and frontal cortex) from control and parkinsonian patients. BDNF in the human brain (the order of ng/mg protein) was significantly lower specifically in the nigrostriatal dopamine (DA) regions from parkinsonian patients than in those from control patients. The concentration of nerve growth factor (NGF) was also significantly decreased in the substantia nigra of parkinsonian patients in comparison with that in the controls. Since BDNF and NGF may play important roles in survival and differentiation of neuronal cells, the present data indicate that the lack of neurotrophins, especially BDNF, may be involved in the pathogenesis of PD during progress of neurodegeneration of the nigrostriatal DA neurons.
