Fig. 5.
Schematic of hypofibrinolysis. Hypofibrinolysis occurs from either lack of release of plasminogen activators or increase basal expression of inhibitors, or a combination of both. This figure represents the multiple steps at which tPA release can be impaired from the endothelial cells and local neurons. Increased release of PAI-1 can occur in multiple cell lines, often due to cytokines and other stimuli. PAI-1, plasminogen activator inhibitor 1; tPA, tissue plasminogen activator.
