摘要:

胰高血糖素样肽1 (glucagon-like peptide 1, GLP-1)作为一种肠促胰岛素,主要由肠道L细胞分泌,由于其能够有效促进胰岛素的释放从而降低血糖,因此GLP-1及其类似物在2型糖尿病的治疗上具有良好的应用前景。本研究优化了慢病毒感染类器官的方法,利用该方法成功构建了GLP-1过表达的小鼠小肠类器官(organoids)。结果显示该类器官分泌的GLP-1能够有效地提高野生型及糖尿病小鼠的葡萄糖耐受能力。因此,本研究构建的GLP-1过表达类器官可以为2型糖尿病的治疗提供一种新的策略。

Abstract:

As a potent insulinotrophic hormone, glucagon-like peptide 1 (GLP-1) is mainly secreted by intestinal L cells, which can effectively promote the release of insulin and thus reduce blood glucose. Therefore, GLP-1 and its analogs have a good prospect in the treatment of type 2 diabetes. In this study, we constructed mouse intestinal organoids that overexpress GLP-1 by optimizing the GLP-1 lentivirus infection method. We found that supernatants secreted by the GLP-1 overexpression organoids effectively enhanced glucose tolerance in wild-type and diabetic mouse. Thus, the GLP-1 overexpression organoids built in this study may provide a novel strategy for the treatment of type 2 diabetes.

Key words: GLP-1, type 2 diabetes, intestinal organoids
