Adenylate cyclase regulation in intact cultured myocardial cells.


To examine the coupling of cardiac cell-surface beta-adrenergic receptors to adenylate cyclase activation and contractile response, we studied this receptor-effector response system in monolayers of spontaneously contracting chick embryo ventricular cells under physiological conditions. The hydrophilic ligand 3H-CGP12177 identified uniformly high-agonist… (More)
