  • Abstract
  • Look Inside

 The discovery of permanent human parkinsonism due to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and the subsequent production of MPTP-induced monkey parkinsonism in 1983 have resulted in a great impact on both the clinical and basic research fields of Parkinson's disease. Its intravenous, intraperitoneal or intramuscular injection or even oral administration to monkeys causes a clinical syndrome almost identical to Parkinson's disease with a good response to L-dopa and/or dopamine agonist therapy and a selective degeneration of the substantia nigra pars compacta. Using a protracted MPTP regimen and older monkeys, locus coeruleus lesions and eosinophilic inclusion bodies have also been reported. In contrast to its marked effects in primates, MPTP has been much less effective in lower animal species, especially rodents. Mechanism of action of MPTP with theories on anatomic and species selectivity were reviewed, including the discussion whether the principal damage to nigrostriatal neurons is incurred at the nerve terminal or cell body. Finally, various kinds of ongoing experimental research works using MPTP monkey were described. These approaches will greatly promote our understanding of both Parkinson's disease and the functions of the basal ganglia and dopamine system.
