  • 功能：
    Regulator of osteoclastogenesis which plays an important bone-specific function in osteoclast differentiation.

    2. OSCAR can play a proinflammatory role in monocyte-derived cells and may contribute crucially on multiple levels to rheumatoid arthritis pathogenesis. PMID: 26786702
    3. Each domain of OSCAR binds a collagen triple-helical peptide; the primary site is on the C-terminal domain in contrast to GPVI and LAIR-1. PMID: 26552697
    4. OSCAR is a receptor for surfactant protein D that activates TNF-alpha release from human CCR2+ inflammatory monocytes. PMID: 25716998

    6. Plasma OSCAR level was higher in the serum of RA patients than controls, and higher in patients with destructive RA rather than non-destructive RA. PMID: 24448348
    7. Rotative stress in mouse cells results in increased levels of Oscar transcription. PMID: 22949349

    9. OSCAR is expressed in vascular endothelial cells and is regulated by oxLDL involving NFATc1 PMID: 22009730
    10. Data suggest that OSCAR is a collagen receptor that binds to specific collagen motifs and costimulates osteoclastogenesis in DAP12-deficient humans and mice. PMID: 21841309
    11. This review discusses the structure-function relationship, expression pattern, and physiological role of OSCAR in osteoimmunology and summarizes its potential implications for human diseases. PMID: 21172874
    12. hOSCAR thus represents a novel class of molecule expressed by dendritic cells involved in the initiation of the immune response. PMID: 15155468
    13. ligation of OSCAR promotes dendritic cell survival by an ERK- and PI3K-dependent pathway, linked to expression of the Bcl-2 and Bcl-x(L) antiapoptotic molecules PMID: 15650060
    14. Human OSCAR mediates the rescue from apoptosis and the cooperation between dendritic cells and antigen-specific T cells that is prevented by CD85j receptor. PMID: 15905516
    15. Promoter variant in OSCAR gene (OSCAR-2322A>G) might be one of genetic determinants of bone density in postmenopausal women. PMID: 16007331

    17. OSCAR is a functional receptor on monocytes and neutrophils, involved in the induction of the primary proinflammatory cascade and the initiation of downstream immune responses. PMID: 16493074
    18. OSCAR (osteoclast associated immunoglobulin-like receptor)is expressed by erosion front osteoclasts and by synovial microvessels mononuclear cells. OSCAR is induced in monocytes of rheumatod arthritis patients, facilitating osteoclast differentiation PMID: 18821671
