We investigated the intrinsic efficacy of this compound at the D2 dopamine receptor subtype using both: (1) a forskolin-dependent adenylyl cyclase inhibition assay and (2) an electrophysiological assay for evaluating coupling to G-protein-coupled inwardly rectifying potassium...

... of senescent animals, which was more pronounced for the D1 subtype. Chronic treatment with cinnarizine, an organic Ca 2+ channel antagonist, alters both D1 and D2 receptor densities, with a higher sensitivity of the Dl subtype. These results could indicate that the interactions between dopamine receptor...
