GLP-1:胰高血糖素(Glucagon)在糖代谢和体内平衡中起重要作用,通过释放糖原和糖酵解调节血糖。作为反调节激素的胰岛素,当血糖升高时,胰岛素可诱导低血糖。胰高血糖素样肽-1(Glucagon-like peptide-1, GLP-1)是一个具有强的**糖依赖的胰岛素释放的肽,在胃运动性和抑制血糖水平上起重要作用。还可能参与外周组织糖的控制,不依赖胰岛素的作用。具有促进肠上皮生长等作用。GLP-1属于胰高血糖素家族成员。
GLP-1 is a incretion hormone, which has been shown to stimulate secretion of insulin in the presence of elevated blood glucose concentrations, but not during periods of low blood glucose concentrations (hypoglycemia). GLP-1 is released from gut endocrine cells in response to nutrient ingestion. The hormone is a physiologic mediator of satiety and regulates energy absorption and disposal. GLP-1 is an insulinotropic hormone that has the ability to render pancreatic beta cells glucose-competent. It has been used in the therapy of type-2 diabetes. GLP-1 has cytokine activity, although it is not classified as such due its small size GLP-1 enhances cell differentiation, plays a role in tissue regeneration, and mediates cytoprotection. |
