Webbeceptor stimulation inhibits prolactin gene r transcription, the synthesis and release of prolactin, and lactotroph proliferation. Other factors also influence prolactin secretion: serotonin, thyrotropin releasing hormone (TRH) and oestrogen have stimulatory effects; and gammaaminobutyric acid (GABA) has an inhibitory effect (Fig. 1). WebbDopamine inhibits prolactin release by stimulating D2 receptors and serotonin induces prolactin release by 5HT-2A receptors.
