It is emerged as an incretin hormone since its discovery for it could facilitate the release of insulin and reduce insulin resistance (IR). However, apart from stimulating insulin secretion, GLP-1 possesses broader pharmacological effects such as anti-inflammatory, neuro-protection, regulating blood pressure (BP) and reducing lipotoxicity, which are interconnected to physiological and pathological process of Alzheimer's disease (AD), hypertension and non-alcoholic steatohepatitis (NASH). Currently, underlying mechanism of GLP-1 multiple effects are still not fully illustrated and a better understanding of these effects may help identify promising therapeutic targets of AD, hypertension and NASH. Therefore, we focus on biological characteristics of GLP-1, render an overview on the mechanism of GLP-1 effects in diseases and ventilate feasible therapeutic presumption of GLP-1 analogues in related diseases in this review.
