摘要 Exendin-4(Ex-4)是胰高糖素样肽(glucagon-like peptide-1,GLP-1)受体激动剂,与GLP-1有53%同源性,可与胰高糖素样肽受体(glucagon-like peptide-1 receptor,GLP-1R)结合产生相应的生物学效应。GLP-1通过葡萄糖依赖性途径调节维持血糖稳定,然而天然GLP-1半衰期很短,释放入血后很快被二肽基肽酶Ⅳ(dipeptidyl-peptidase,DPP-4)降解失活。Ex-4半衰期较长,除调节血糖外,对保护血管内皮、调节脂质代谢等方面均有积极作用,表明其在高血压、动脉粥样硬化等心血管疾病的预防和治疗上具有潜在价值。本文主要对Ex-4、GLP-1及其类似物在心血管系统的生物学作用进行综述。
