“…On the other hand, vasoactive intestinal peptide (VIP) has been reported to stimulate specifically PRL release from rat pituitary lactotrophs [6]. It appears that this effect is mediated by cyclic AMP (cAMP) [7,8]. Here, we investigated whether SRIF can interact with the stimulatory effect of VIP on PRL release by rat pituitary cells in culture, and whether this action is mediated by a modification of the cAMP accumulation induced by VIP.…”
