Figure 4From: mGluR5 positive modulators both potentiate activation and restore inhibition in NMDA receptors by PKC dependent pathwayPKC inhibitor influences the effects of mGluR5 modulators on NMDA receptor activation and suppression. Pretreatment of hippocampal slices with chelerythrine (10 μM), a PKC inhibitor, inhibited the enhancing effects of DFB (10 μM), CHPG (50 μM), and CDPPB (10 μM) on NMDA-induced field potentials (a) and reversed the attenuating effects of mGluR5 modulators on ketamine (b, 10 μM) or D-APV (c, 50 μM)-evoked NMDA receptor suppression. All values are expressed as the mean ± S.E.M. (n = 5). Data were statistically analyzed by one-way ANOVA followed by a Student-Newman-Keuls post-hoc test.Back to article page
