Zonisamide 43-53 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 145-149 19429061-7 2009 In contrast, ZNS inhibited the stimulatory effect of IP3R agonist on K(+)-evoked release. Zonisamide 13-16 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 53-57 19429061-9 2009 These results suggest that ZNS-activated N-type VSCC enhances IP3R-associated neurotransmitter release during resting stage, whereas ZNS-induced suppression of P- and L-type VSCCs possibly attenuates IP3R-associated neurotransmitter release during neuronal hyperexcitability. Zonisamide 27-30 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 62-66 19429061-9 2009 These results suggest that ZNS-activated N-type VSCC enhances IP3R-associated neurotransmitter release during resting stage, whereas ZNS-induced suppression of P- and L-type VSCCs possibly attenuates IP3R-associated neurotransmitter release during neuronal hyperexcitability. Zonisamide 27-30 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 200-204 19429061-10 2009 Therefore, the combination of both of these two actions of ZNS on IP3R-associated neurotransmitter release mechanism seems to be involved, at least in part, in the mechanisms of antiepileptic and neuroprotective actions of ZNS. Zonisamide 59-62 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 66-70 19429061-10 2009 Therefore, the combination of both of these two actions of ZNS on IP3R-associated neurotransmitter release mechanism seems to be involved, at least in part, in the mechanisms of antiepileptic and neuroprotective actions of ZNS. Zonisamide 223-226 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 66-70 19429061-6 2009 The latter effects of IP3R agonist were weakly enhanced by ZNS, but such stimulatory action of ZNS was abolished by extracellular Ca(2+) depletion. Zonisamide 59-62 inositol 1,4,5-trisphosphate receptor, type 1 Rattus norvegicus 22-26
