In vivo, exercise can stimulate skeletal muscle cells to secrete and release myokines into blood circulation, which will participate in metabolism and act on multiple organs or systems. Recently, the relationship between myokines and diabetes mellitus was a hot research topic, and myokines may be potential targets for the diagnosis, monitoring, prevention and treatment of diabetes mellitus. In this review, we elucidated the multiple effects of common myokines in the pathogenesis and therapy of diabetes mellitus, which will provide a theoretical foundation of the mechanism in the positive effects of exercises on humans.展开更多
