It has been recently reported that, after physical exercise activity, the skeletal muscle releases Irisin, the newly identified myokine able of driving transition of white adipocytes to brown, following a phenomenon known as the browning response. This result has suggested that skeletal muscle is crucial in the regulation of energy homeostasis, supporting the idea that it can be considered an endocrine organ that targets adipose tissue by promoting energy expenditure. In accor...

Irisin is a hormone-like myokine secreted from skeletal muscle in response to exercise. Considering that an intimate relationship between skeletal muscle and bone has been well established and that physical exercise physiologically stimulates the skeleton strengthening, we explored the involvement of Irisin on bone metabolism.Our findings demonstrated that the myokine Irisin improves cortical bone mass and geometry in vivo, supporting the idea t...
