在体外已经证实了KATP通道活性在介导GLP-1释放中的重要性,同时也证实人L-细胞中存在KATP通道的Kir6.2/SUR1通道复合物[31],但KATP通道的Kir6.2/SUR1通道复合物是否在人体中介导GLP-1释放这一过程的作用还有待证实。 图2 L-细胞内...
就在哈本纳发现GLP-1作用的同时,丹麦的外科医生、生理学家詹斯·霍尔斯特 (Jens Juul Holst) 通过胃溃疡手术方面的工作也独立地发现了GLP-1是一种新的肠促胰素。霍尔斯特观察到,他的许多接受肠道溃疡手术的患者,在餐后会出现胰岛素峰值和低血糖的情况。霍尔斯特最终在人体血液中发现了一类...
GIP刺激迷走神经传入传递,随后激活迷走传出神经元和肠神经元,释放乙酰胆碱和/或GRP来刺激远端肠道释放GLP-1,触发GLP-1分泌,而营养物质如能到达远端肠道时,与L-细胞的直接接触也会触发GLP-1分泌进入循环。 02 中枢GLP-1分泌的内分泌调节 后脑孤束核(NTS)尾部的的GCG+神经元是内源性脑GLP-1的主要来源[71]。NT...
临床前数据表明,相较于单独GLP-1类似物或单独雌激素,GLP-1/雌激素结合产物可增强小鼠厌食、减重、促胰岛素和胰岛保存作用[83-85]。而这种GLP-1/雌激素结合物并没有雌激素独有的促子宫内膜增生的效应,仅体现GLP-1成分介导的治疗指标改善。GLP-1R靶向作用也被用来将地塞米松的抗炎特性传递到代谢相关组织。尽管糖皮...
GLP-1 also slows digestion and contributes to a full sensation. It does this specifically by slowing the rate at which the stomach empties. This effect decreases appetite, which lessens food consumption. Improved blood sugar regulation and weight management can be a desired side effect of appetite...

particularly during the postprandial period Upon ingestion of food, GLP-1 is secreted in into the bloodstream and enhances glucose dependent insulin secretion from beta-cells GLP-1 suppresses inappropriately elevated glucagon secretion from alpha cells Lower levels of glucagon lead to a reduction of glu...
Glucagon-like peptide-1 (GLP-1) released from gut enteroendocrine cells controls meal-related glycemic excursions through augmentation of insulin and inhibition of glucagon secretion. GLP-1 also inhibits gastric emptying and food intake, actions maximizing nutrient absorption while limiting weight gain. ...
