Research Abstract |
Glutamate neurotoxicity was found to at least in part involve mitochondrial membrane potential disruption, mPTP orchestration, mitochondrial free Ca^<2+> levels and UCP2 expression in rat hippocampal and cortical neurons. In HEK293 cells with acquired NMDAR channels and overexpressed UCP2, a more marked increase was seen in mitochondrial free Ca^<2+> levels, in addition to more severe cell death, after the exposure to NMDA than in cells without UCP2 overexpression. Accordingly, UCP2 could play a role as a determinant of the neurotoxicity mediated by NMDAR through a mechanism related to the modulation of mitochondrial free Ca^<2+> levels in neurons.
