ABSTRACT
A disintegrin and metalloproteases (ADAMs) are a family of proteins that have been reported to be involved in several inflammatory conditions. We examined the secretion of ADAM-10 in biological fluids from patients with rheumatoid arthritis (RA) and the role it plays in monocyte migration. ADAM-10 levels were measured using enzyme-linked immunosorbent assays and immunofluorescence. To examine the role of ADAM-10 in RA synovial fluids (SFs), we studied THP-1 (human acute monocyte leukemia cell line) and monocyte chemotaxis. To determine whether ADAM-10 plays a role in cell proliferation in the RA synovium, we assayed the proliferation of ADAM-10 small interfering RNA (siRNA)-transfected RA fibroblast-like synoviocytes (FLSs). The ADAM-10 level in RA serum was significantly higher than that in normal serum and was correlated with a disease activity score of 28. ADAM-10-depleted RA SFs showed a decrease in THP-1 and monocyte migratory activity compared with that of sham-depleted controls. ADAM-10 siRNA inhibited monocyte adhesion to RA FLSs. Finally, blocking ADAM-10 secretion in RA FLSs resulted in decreased production of fractalkine/CX3CL1 and vascular endothelial cell growth factor. These data indicate that ADAM-10 plays a role in monocyte migration in RA and suggest that targeting ADAM-10 may provide a method of decreasing inflammation and potentially treating other inflammatory diseases.
