NMDA–D1 and NMDA–D2 Receptor Interactions

NMDA–D1 Receptor Interactions
Brain slices, oocytesStriatum↑ NMDA responsescAMP–PKA–DARPP-32 [31, 32, 36, 43, 42]
Dissociated cellsCortexCa2+ [37, 44, 45, 46]
Brain slicesN. AccumbensD1/5↑ NMDA responsesPKC, Ca2+, PKA [38, 35, 112]

Cell culturesStriatum↑ D1receptors in spinesCa2+-dependent [52]
Organotypic culturesStriatum↑ D1receptors in spinesAllosteric change, diffusion trap [53]
HEK293, cell culturesHippocampus↓ NMDA currents
