摘要 胰岛淀粉样多肽(islet amyloid polypeptide,IAPP)是1986年瑞典学者Westermark et al从胰岛素瘤患者的瘤组织,糖尿病猫及Ⅱ型糖尿病患者胰岛淀粉样沉积物中分离出来的一种多肽,几乎在同时,英国生物化学家Cooper et al也从Ⅱ型糖尿病患者的胰岛淀粉样沉积物中分离出该肽。IAPP又称为amylin,对IAPP的分子结构、基因表达和生理作用等已有许多报道。近年来,在IAPP定位、表达及胃肠胰IAPP免疫反应(immunoreactive,IR)细胞定位、发生、发育方面的研究报道,为探讨IAPP的生理作用及疾病状态下的改变,提供了形态学依据,现综述如下。
