Dopamine inhibited basal, TRH-, IBMX- and A23187-stimulated prolactin secretion from rat anterior pituitary cells. However, dopamine did not inhibit prolactin secretion stimulated by elevated K+ concentrations. These data are interpreted in terms of dopaminergic inhibition of both cyclic AMP production and Ca2+ influx through agonist-, but not voltage-, dependent Ca2+ channels.
