摘要 表皮生长因子受体(EGFR)信号转导在调节β细胞数量及其功能中起重要作用,为糖尿病的治疗提供了新方向,但目前对其作用机制仍知之甚少。发育生物学研究表明,EGFR的缺乏会造成小鼠胰岛发育受损。若EGFR信号减弱,会导致β细胞增殖明显减少。而其配体,如β-细胞调节素(BTC)可专一性地增加β细胞增殖和再生。本文对EGFR及其配体在胰腺中的表达及对胰腺发育的影响、β细胞中EGFR信号通路以及对β细胞数量和功能的影响等方面的研究进展进行了综述。 Epidermal growth factor receptor(EGFR) cell signaling plays a central role in β-cell mass/function regulation, and provides a new strategy for the treatment of diabetes,but its mechanisms of action remain poorly understood.In developmental biology,pancreatic islet development is impaired in lacking EGFR of mice.The attenuation of EGFR signaling in the islets leads to markedly reduced β-cell proliferation.EGFR ligands BTC can increase proliferation and neogenesis.In this article EGFR and their ligands in the pancreas,EGFR cell signaling,and EGFR effects in pancreatic β-cell mass/function regulation were reviewed.
