Abstract:
BACKGROUNDOsteoclast-associated receptor (OSCAR) is a member of the newly identified leukocyte receptor complex, and has recently been described as a key molecule in osteoclastogenesis. In this study, we measured the levels of soluble osteoclast-associated receptor (sOSCAR) in the serum of rheumatoid arthritis (RA) patients and healthy controls to examine whether sOSCAR may play a role in the process of inflammatory arthritis.
METHODSEnzyme-linked immunosorbent assay (ELISA) was used to measure the levels of sOSCAR in the serum of 40 healthy controls and 40 RA patients.
RESULTSThe serum levels of sOSCAR were significantly lower in RA patients than in healthy controls, and were inversely associated with inflammatory activity.
CONCLUSIONsOSCAR is decreased in patients with RA and reduced levels of the protein are associated with increased inflammatory response.
