Abstract:Irisin is a newly discovered myogenic factor which can be induced by exercise. In recent years, Irisin has attracted much attention because of its ability to promote the browning of white adipose tissue and promote the metabolism of sugar and fat. Experimental studies have shown that Irisin has certain clinical value in the treatment of type 2 diabetes mellitus, cardiovascular disease, Alzheimer's disease, bone metabolism, cancer, and other diseases. This article will summarize the published research on Irisin at home and abroad and explore its role and possible mechanism, in order to provide direction for the next clinical research.
