The role of the plasminogen activators urokinase-PA and tissue-type PA in arthritis

Grant number: 299944


Many diseases, such as rheumatoid arthritis (RA), are inflammatory by nature. Intra-articular fibrin deposition is an early and persistent hallmark of inflammatory responses, resulting from an altered balance between coagulation (the production of fibrin) and fibrinolysis (the breakdown of fibrin). This fibrin accumulation can have adverse effects in RA, including mediating and-or enhancing inflammation, and contributing to subsequent joint damage. The plasminogen activators (PA), urokinase PA (u-PA) and tissue-type PA (t-PA) convert plasminogen into plasmin which can then breakdown the accumulated fibrin. Their presence in RA patients would therefore be beneficial. However, u-PA is also imp..
