Effects of amantadine and memantine on NMDA receptor-mediated glutamate toxicity were studied in cultured cerebellar, cortical and mesencephalic neurons. Both drugs protected cerebellar and cortical neurons against glutamate toxicity, memantine being consistently more effective than amantadine but less effective than MK-801. Glutamate toxicity of(More)
In striatal neurons in primary culture quisqualate potently stimulated the formation of inositol phosphates via a metabotropic receptor we recently termed Qp in order to distinguish it from the classical ionotropic quisqualate receptor termed Qi. Here we show that 10 microM of quisqualate activated in a rapid and transient manner protein kinase C as(More)
Recent reports suggest that NMDA receptor antagonists when administered in vivo can protect dopaminergic neurons from the toxic actions of MPP+. In the present study the possible neuro-protective effects against MPP+ toxicity of the noncompetitive NMDA receptor antagonist MK-801 was studied in primary cultures of fetal rat mesencephalic dopamine neurons.(More)
Cleavage of methotrexate into glutamate and diaminomethylpteroate by intrathecal glutamate carboxypeptidase is a new approach to the treatment of acute methotrexate neurotoxicity. The simulation of glutamate carboxypeptidase rescue from high-dose methotrexate in neuron astrocyte cocultures of rat cerebellum or cerebral cortex resulted in a selective,(More)
The delayed neuronal death (DND) resulting from brief forebrain ischemia has recently been reported to be markedly attenuated by parenteral administration of the reversible protein synthesis inhibitor, anisomycin. Previous work suggests that ischemia-induced DND is mediated by glutamate acting at one or more glutamate receptors, since glutamate receptor(More)
