[Control of bone resorption by RANKL-RANK system].


Differentiation and function of osteoclasts is regulated by RANKL and OPG, both of which are produced by osteoblasts. Osteoclast precursors express RANK, the receptor of RANKL. The activation of the RANKL-RANK system stimulates osteoclast differentiation and function. OPG is a decoy receptor of RANKL, which inhibits the RANKL-RANK interaction. Several… (More)
