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...

LIGHT (TNFSF14), expressed by different cells of the immune system, binds two trans-membrane receptors: HVEM and LTβR. It is over-expressed in erosive rheumatoid arthritis and lytic myeloma-bone disease and controversial data have been published on its role osteoclast (OC) formation in vitro. Here, we investigated the role of LIGHT on in vitro murine osteoclastogenesis model and bone phenotype in LIGHT−/− mice. Firstly, we showed that murin...
