背景介绍
TNFRSF11B is a secreted Protein, containing 2 death domains and 4 TNFR-Cys repeats. TNFRSF11B is a decoy Receptor for the Receptor activator of nuclear factor kappa B Ligand (RANKL). By binding RANKL, TNFRSF11B inhibits nuclear kappa B (NF-κB) which is a central and rapid acting transcription factor for immune-related genes, and a key regulator of inflammation, innate immunity, and cell survival and differentiation. TNFRSF11B levels are influenced by voltage-dependent calcium channelsCav1.2. TNFRSF11B can reduce the production of osteoclasts by inhibiting the differentiation of osteoclast precursors (osteoclasts are related to monocytes/ macrophages and are Derived from granulocyte/ macrophage-forming colony units (CFU-GM)) into osteoclasts and also regulates the resorption of osteoclasts in vitroand in vivo. TNFRSF11B binding to RANKL on osteoblast/ stromal cells, blocks the RANKL-RANK Ligand interaction between osteoblast/ stromal cells and osteoclast precursors. This has the effect of inhibiting the differentiation of the osteoclast precursor into a mature osteoclast.
