Plasmin

Plasmin (PL) is produced by PLG under the action of its activator (PA) and is the most direct factor that causes fibrin degradation. Under physiological conditions, PL is combined with PLG, t-PA, etc. on the surface of vascular endothelial cells. Once a small amount of fibrin is formed, PLG is activated to PL, which in turn degrades fibrin locally to avoid thrombosis and ensure blood flow. unobstructed.
