This study presents 'in vitro' evidence for a protection of cultured d
opaminergic neurons against the toxicity of 6-hydroxydopamine (6-OHDA)
and 1-methyl-4-phenylpyridinium (MPP+) by pretreatment with BTCP, a s
elective and potent dopamine (DA) uptake blocker. Moreover, we show th
at, at low concentration (10 nM), treatment with MPP+, which is more s
elective than 6-OHDA for dopaminergic neurons, is followed by some reg
eneration of these neurons.
