OSCAR (Osteoclast Associated Receptor) is a transmembrane glycoprotein belonging to the immunoglobulin superfamily, first identified in the early 2000s for its role in osteoclast differentiation and immune regulation. It is primarily expressed on osteoclast precursors, dendritic cells, monocytes, and certain activated lymphocytes. OSCAR functions as a co-stimulatory receptor, interacting with ligands such as collagenous motifs in the extracellular matrix or soluble factors released during tissue remodeling.
In the immune system, OSCAR is closely associated with innate immunity. It pairs with the Fc receptor γ-chain (FcRγ) to activate signaling pathways, including calcium mobilization and NF-κB activation, which promote osteoclastogenesis and modulate inflammatory responses. OSCAR’s dual role in bone metabolism and immunity links it to pathologies like rheumatoid arthritis and osteoporosis, where dysregulated osteoclast activity and immune activation drive tissue damage.
OSCAR antibodies, developed to target this receptor, have become valuable tools in research and therapeutics. They help elucidate OSCAR’s mechanistic contributions to bone resorption and inflammation. In preclinical studies, blocking OSCAR antibodies show potential in mitigating bone loss in inflammatory diseases. However, their clinical application remains exploratory, with ongoing studies aiming to balance efficacy and immune tolerance. OSCAR thus represents a promising intersection of immunology and skeletal biology. (298 words)
