A group of researchers have shown the health benefits of a hormone, irisine, which secretes muscle cells during exercise. In addition, the hormone has been isolated and it has been shown that injected into mice has the same effects as exercise. In view of this, it is suggested that irisine may have a therapeutic use, especially in obesity and diabetes, but perhaps also in some cancers. The details of the study have been published in the scientific journal Nature. According to the study, the hormone irisine has a direct influence on adipose tissue, either through exercise or injection into blood, the irisín turns white fat (poor health) into brown (beneficial) fat. In addition, glucose tolerance increases. In an experiment with sedentary mice, they have shown that after ten days of irisine injection, blood glucose levels and insulin levels were better than before starting the experiment. At the same time, no side effects were detected. Since the irisine of mice is the same as that of people, researchers hope it can be used to treat patients.
