In rheumatoid arthritis (RA) the synovial membrane proliferates and invades the underlying tissues. The cell-associated fibrinolytic system (urokinase-type plasminogen activator, uPA; uPA receptor, uPAR; plasminogen activator inhibitor-type 1, PAI-1) is pivotal in cell invasion and proliferation. For this reason, the expression and the role of such enzymatic system was investigated in synovial fibroblasts (SF) of normal and RA patients.
