Brown fat and obesity: light at the end of the tunnel?

The researchers plan to continue studying the functions of Tyk2 and Stat3 proteins in order to gain a more complete understanding of the mechanisms of formation of brown adipose tissue. They hope that their work will provide new targets not only for the treatment of obesity, but also for the prevention of diseases associated with it.
