Abstract

Pituitary adenylate cyclase-activating polypeptide (PACAP) is an ancestral molecule that was isolated from sheep hypothalamic extracts based on its action to stimulate cAMP production by pituitary cell cultures. PACAP is one of a number of ligands that coordinate with GnRH to control reproduction. While initially viewed as a hypothalamic releasing factor, PACAP and its receptors are widely distributed, and there is growing evidence that PACAP functions as a paracrine/autocrine regulator in the CNS, pituitary, gonads and placenta, among other tissues. This review will summarize current knowledge concerning the expression and function of PACAP in the hypothalamic-pituitary-gonadal axis with special emphasis on its role in pituitary function in the fetus and newborn.

摘要

垂体腺苷酸环化酶激活肽(PACAP)是一种古老的分子,最初从羊下丘脑提取物中分离出来,因其能刺激垂体细胞培养物中 cAMP 的产生而得名。PACAP 是与 GnRH 协同作用以控制生殖的多种配体之一。虽然最初被视为下丘脑释放因子,但 PACAP 及其受体广泛分布,越来越多的证据表明 PACAP 在中枢神经系统、垂体、性腺和胎盘等组织中作为旁分泌/自分泌调节剂发挥作用。 本文综述了 PACAP 在下丘脑-垂体-性腺轴中的表达和功能的最新知识,特别强调了其在胎儿和新生儿垂体功能中的作用。
