NMDA-sensitive L-[3H]glutamate binding in cerebral cortex of El mice.
NMDA-sensitive L-[3H]glutamate binding was examined in the brains of El mice, a genetic animal model of epilepsy, and in ddY mice. In whole brain, Scatchard analysis showed that both stimulated and unstimulated El mice had significantly lower Bmax values for binding than did ddY mice. In regional studies, the binding of NMDA-sensitive L-[3H]glutamate was significantly less in the cerebral cortex of both stimulated and unstimulated El mice than in that of ddY mice. These data suggest that NMDA receptors may be involved in the genetic susceptibility of El mice to seizures.
