摘　　要： 生长激素释放肽(Ghrelin)是在哺乳动物中发现的第一个生长激素促分泌素受体的内源性配体,部分鱼类的Ghrelin基因和肽链结构已经被确定。与哺乳动物相似,鱼类Ghrelin的主要分泌部位也在消化道,但在脑、肾脏、鳃、心脏等组织中也有少量分泌。鱼类的Ghrelin参与多种生理功能的调节,包括促进摄食以及调节脑垂体内多种激素的分泌,可促进脑垂体分泌LH和GH,某些鱼类Ghrelin可能具有促进脑垂体分泌PRL的功能。本文综述了近年来鱼类Ghrelin结构与生理功能研究概况,旨在为丰富鱼类内分泌生理学研究提供参考资料。 Ghrelin was originally purified and characterized as the first identified endogenous ligand of the growth hormone secretagogue receptor in mammals. By now, the gene and peptide structures of ghrelin have been identified in several fishes. As in mammals, ghrelin is mainly secreted in the digestive tract of fish and there are minor levels of ghrelin secreted in the brain, kidney, gills, heart and other tissues, and it is involved in the regulation of a number of physiological functions, including stimulating food intake in fishes and modulating the release of pituitary hormone such as stimulating luteinizing hormone and growth hormone release from the pituitary in fishes, and stimulating the release of prolactin in pituitary in some fishes. This review summarized the research survey in the structure and physiological functions of ghrelin in fishes in recent years in order to provide reference for the enrichment of research content in endocrine physiology in fishes.
