1 Tranexamic acid mediates proinflammatory and anti-inflammatory signaling via complement C5a regulation in a plasminogen activator-dependent manner. Tranexamic Acid plasminogen Homo sapiens
2 Tranexamic acid (TXA) blocks both the tPA-dependent generation of plasmin on blood clots as well as active plasmin binding to polymerized fibrin, and is commonly administered for bleeding in trauma to limit fibrinolysis. Tranexamic Acid plasminogen Homo sapiens
3 Tranexamic acid (TXA) blocks both the tPA-dependent generation of plasmin on blood clots as well as active plasmin binding to polymerized fibrin, and is commonly administered for bleeding in trauma to limit fibrinolysis. Tranexamic Acid plasminogen Homo sapiens
4 Tranexamic acid (TXA) blocks both the tPA-dependent generation of plasmin on blood clots as well as active plasmin binding to polymerized fibrin, and is commonly administered for bleeding in trauma to limit fibrinolysis. Tranexamic Acid plasminogen Homo sapiens
5 Tranexamic acid (TXA) blocks both the tPA-dependent generation of plasmin on blood clots as well as active plasmin binding to polymerized fibrin, and is commonly administered for bleeding in trauma to limit fibrinolysis. Tranexamic Acid plasminogen Homo sapiens
6 Because TXA does not block uPA-dependent plasmin generation from PLG and instead augments it, we hypothesized that administration of TXA could enhance or inhibit proinflammatory C5a formation in a PLG activator-dependent manner. Tranexamic Acid plasminogen Homo sapiens
7 RESULTS: Plasmin-mediated fibrinolysis by tPA in clotted PPP led to an approximately threefold increase in C5a production (p < 0.0001), which was significantly inhibited by TXA (p < 0.001). Tranexamic Acid plasminogen Homo sapiens
8 CONCLUSIONS: Tranexamic acid administration can have proinflammatory or anti-inflammatory effects through regulating C5a generation by plasmin, depending on the predominating PLG activator. Tranexamic Acid plasminogen Homo sapiens
9 CONCLUSIONS: Tranexamic acid administration can have proinflammatory or anti-inflammatory effects through regulating C5a generation by plasmin, depending on the predominating PLG activator. Tranexamic Acid plasminogen Homo sapiens
10 Tranexamic acid may cause significant inflammatory C5a elevations in injured tissues by augmenting uPA-mediated plasmin generation in a fibrin-independent manner. Tranexamic Acid plasminogen Homo sapiens
