Growth hormone secretagogue receptor , g 是一种生长激素促分泌素受体
3.
Background : ghrelin is a 28 - amino acid endogenous peptide recently identified in the secretory granules of x / a - like cells in the rat stomach , which can act on the growth hormone secretagogue receptor to accelerate the secretion of growth hormone . it was identified that ghrelin - immunoreactive cell and its receptor localize in areas of brain , such as hypothalamus ( pvn , arc ) , hippocampus , adenohypophysis and so on . motilin is a 22 - amino acid peptide secreted from the upper part of the small intestine , which regulates the interdigestive motility of gastric 背景资料： ghrelin是新发现的由28个氨基酸组成的内源性脑肠肽，由胃部泌酸腺x / a样内分泌细胞分泌， ghrelin免疫活性神经元及其受体在中枢神经系统中如下丘脑室旁核( paraventricularneucleus ， pvn ) 、弓状核( arcuatenucleus ， arc ) 、海马区及腺垂体等均有不同浓度的分布，可与生长素促泌物受体( growthhormonesecretagoguereceptor ， ghsr )结合促进生长素( growthhormone ， gh )分泌。
