NIH researchers discover protein that appears to regulate bone mass loss, the cause of osteoporosis

... density. A new study, published online this week, confirms this unexpected connection. CD40 ligand appears to regulate cells that secrete chemicals that block bone metabolism, and the loss of this protein in people with X-linked Hyper IgM Syndrome appears to accelerate bone loss. The next step, say the resea...
