Toxic effects of potential environmental neurotoxins related to 1-methyl-4-phenylpyridinium on cultured rat dopaminergic neurons.


Dopaminergic rat mesencephalic neurons in culture were exposed to a group of potential environmental neurotoxins. These cultures, which contained 0.5 to 1% dopaminergic neurons, were a suitable tool for determining nonselective and selective dopaminergic cytotoxicity. Selective toxicity was quantitated as the concentration which destroyed half of the… (More)
