title: Age-dependent effects of 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP).
abstract: The neurotoxic effects of 1-methyl-4-phenyl-1,2,5,6-tetrahydropyridine (MPTP) have been shown to be dependent upon its conversion to 1-methyl-4-phenyl pyridine ion (MPP+) by monoamine oxidase. Since central monoamine oxidase activity increases with age, the neurotoxic effects of MPTP should be age-dependent. This hypothesis was evaluated by administering MPTP to three groups of rats differing in age. It was observed that both the lethality and neurotoxicity of MPTP were age-dependent.
