Introduction. Tissue-type plasminogen activator (t-PA) is a serine protease of the neurovascular unit released by endothelial cells 1, neurons 2, and glial cells 3. t-PA is an unusually active zymogen, with full intrinsic activity and low zymogenicity 4. t-PA promotes fibrinolysis via the conversion of the inactive fibrin-bound zymogen plasminogen into plasmin.
