The recent knowledge that 10 years after transplantation surviving human fetal neurons adopt the histopathology of Parkinson's disease suggests that Lewy body formation takes a decade to achieve. To determine whether similar histopathology occurs in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-primate models over a similar timeframe, the brains of two adult monkeys made parkinsonian in their youth with intermittent injections of MPTP were studied. Despite substantial nigral degeneration and increased α-synuclein immunoreactivity within surviving neurons, there was no evidence of Lewy body formation. This suggests that MPTP-induced oxidative stress and inflammation per se are not sufficient for Lewy body formation, or Lewy bodies are human specific.
