Abstract
Methylphenyltetrahydropyridine (MPTP) selectively destroys neuronal cell bodies in the melanin-containing substantia nigra of humans and other primates. We show that methylphenylpyridine (MPP+), an active metabolite of MPTP which is accumulated intraneuronally by the catecholamine uptake system, binds with high affinity to melanin and neuromelanin. MPP+ bound intracellularly to neuromelanin may be released gradually, resulting in subsequent damage to the neurons of the substantia nigra.This publication has 24 references indexed in Scilit:
