Glucagon-like peptide 1 (GLP-1) is both a gut-derived hormone and a neurotransmitter synthesized in the brain. Early reports suggested that GLP-1 acts in the periphery to promote insulin secretion and affect glucose homeostasis, whereas central GLP-1 reduces food intake and body weight. However, current research indicates that in fact, GLP-1 in each location plays a role in these functions. This review summarizes the evidence for involvement of peripheral and brain GLP-1 in food intake regulation and glucose homeostasis and proposes a model for the coordinated actions of GLP-1 at multiple sites.
胰高血糖素样肽1(GLP-1)既是一种源自肠道的激素,也是一种在大脑中合成的神经递质。早期报告表明,GLP-1在外周发挥作用以促进胰岛素分泌并影响葡萄糖稳态,而中枢GLP-1则减少食物摄入和体重。然而,目前的研究表明,实际上,每个部位的GLP-1在这些功能中都发挥作用。这篇综述总结了外周和大脑GLP-1参与食物摄入调节和葡萄糖稳态的证据,并提出了一个GLP-1在多个部位协同作用的模型。
