  • Title: Dopamine inhibition of neurotensin-induced increase in Ca2+ influx into rat pituitary cells.
    Author: Memo M, Carboni E, Trabucchi M, Carruba MO, Spano PF.
    Journal: Brain Res; 1985 Nov 18; 347(2):253-7. PubMed ID: 2415214.
    Abstract:
    In this paper, we report that the intracellular mechanism by which neurotensin stimulates prolactin release involves an increase in Ca2+ uptake by pituitary cells rather than an effect on adenylate cyclase system. In addition, dopamine can prevent neurotensin-induced calcium influx by interacting with dopamine D2-receptors which appear to be completely independent of the adenylate cyclase moiety but are coupled to calcium channels.
