Modulation of Gβγ subunit signaling by aripiprazole and reference DRD2 ligands in HEK-AC2/D2 cells. A. Activation of Gβγ signaling was assessed by measuring DRD2 potentiation of the AC2-stimulated cAMP accumulation in HEK-AC2/D2 cells. B. Antagonism of dopamine’s Gβγ response through the DRD2. Cells were treated with antagonists for 30 min, followed by a 1 h incubation with 300 nM dopamine in the presence of 1 µM PMA and 0.5 mM IBMX. Data shown represent the average and S.E.M. of at least three independent experiments conducted in duplicate.
