Dopaminergic neurotrophic factor for treatment of Parkinson's disease
First Claim
1. A purified form of soluble dopaminergic neurotrophic factor derived from cultured cells of the mammalian peripheral nervous system, said factor comprising a polypeptide of molecular weight between about 9,000 and about 10,000 daltons, said factor being capable of increasing the survival time of fetal, non-mitotic dopamine nerve cells in culture, and of increasing in vivo expression of tyrosine hydroxylase in substantia nigra dopamine nerve cells exposed to said factor, said factor having a neurotrophic effect on substantia nigra dopamine nerve cells.
