WebBone serves as a vast reservoir of calcium. Stimulating net resorption of bone mineral releases calcium and phosphate into blood, and suppressing this effect allows calcium to be deposited in bone. The kidney is critcally important in calcium homeostasis. Under normal blood calcium concentrations, almost all of the calcium that enters ... WebDespite the role of PTH in stimulating bone resorption, it turns out that if given as a once-daily injection, PTH agonists stimulate osteoblasts to promote bone deposition. The newest anabolic treatment for osteoporosis (approved in April 2024) is romosozumab, a monoclonal antibody drug that inhibits the signaling molecule sclerostin.
