Osteoprotegerin (OPG) is a glycoprotein that plays a crucial role in regulating bone metabolism. It is a decoy receptor for the receptor activator of nuclear factor-kappa B ligand (RANKL), which is involved in the process of bone resorption. OPG is primarily produced by osteoblasts (bone-forming cells) but can also be found in other tissues like endothelial cells, smooth muscle cells, and certain immune cells.
OPG is an important regulator not just for bone metabolism but also in inflammation. It modulates immune cell activity, cytokine production, and tissue remodeling in response to inflammation. Elevated OPG levels can be a sign of ongoing inflammatory processes in diseases such as rheumatoid arthritis, atherosclerosis, and other autoimmune disorders.
Biomedica’s Osteoprotegerin ELISA Assay Kit (BI-20403) was highlighted in a recent study! The study assessed serum OPG levels during acute inflammatory states induced by a bacterial or viral infection in children. The researchers investigated whether OPG increases during acute inflammatory states and if its levels correlate with other biomarkers.
