Abstract

Abstract: Dopaminergic neurons in cultures of dissociated cells from fetal rat mesencephalon were exposed to the principal metabolite of the neurotoxin 1‐methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine (MPTP), 1‐methyl‐4‐phenyl‐pyridinium ion (MPP+), and several of its structural analogues. At concentrations between 0.01 and 0.1 μM, MPP+ inhibited catecholamine accumulation as visualized by cytofluorescence. Between 0.1 and 10.0 μM, MPP+ resulted in disappearance of tyrosine hydroxylase immunoreactivity without affecting other cells in the cultures. At concentrations higher than 10 μM, MPP+ was toxic to all cells present in the cultures. The effect of low concentrations of MPP+ on catecholamine cytofluorescence of the dopaminergic neurons was partially reversible. The intermediate concentrations produced irreversible structural changes of tyrosine hydroxylase‐positive cells, resulting in complete disappearance of these neurons. The morphological changes were specific to the dopaminergic neurons and were not evident in other cells viewed with phase contrast microscopy. Of the structural analogues tested, the 1‐ethyl analogue of MPP+ was effective in selectively destroying dopaminergic neurons in our culture system. The antioxidants l‐acetylcarnitine, β‐carotene, and α‐tocopherol failed to protect against MPP+ neurotoxicity when co‐incubated with the toxin.
