WebPlasmin is the primary fibrinolysin, and is activated from plasminogen by either of two primary serine proteases, tPA and uPA. Whereas tPA is synthesized and released by endothelial cells, uPA is produced by monocytes, macrophages, and urinary epithelium. WebApr 19, 2016 · Plasmin is the key enzyme involved in the dissolution of fibrin. It is produced from plasminogen, which is activated by a plasminogen activator; the two primary activators are tissue-type plasminogen activator (tPA) and urinary-type plasminogen activator (uPA), also called urokinase.

Accordingly, fibrin clearance by plasmin activity would reduce fibrin-driven inflammation, and compromised plasminogen activation (or the elimination of plasminogen) would increase inflammation. WebPlasmin (as part of the fibrinolytic pathway) degrades fibrin (and fibrinogen), resulting in FDPs. One of the specific FDPs is fragment D. Dimers of this fragment ( d -dimer) are detected only upon degradation of cross-linked fibrin (indicating active coagulation and fibrinolysis).

WebPlasminogen and tPA bind to lysine residues exposed by fibrinolysis, further accelerating the conversion of plasminogen into plasmin. Plasmin that is bound to fibrin is relatively protected from inhibition by circulating α 2 -antiplasmin. 27 However, α 2 -antiplasmin also binds to fibrin and helps to protect the clot against fibrinolysis. 20, 21 WebPlasmin is the effector protease of the fibrinolytic system, well known for its involvement in fibrin degradation and clot removal.
