title: The role of inflammatory cells and their proteases in extravascular fibrinolysis.
abstract: Extravascular fibrin formation and dissolution is a pivotal event in numerous inflammatory and malignant diseases. In inflammatory cells such as monocytes/macrophages, neutrophil granulocytes appear to interact intimately with hemostasis and regulate the activity of the cascade systems of coagulation and fibrinolysis. Proteases such as neutrophil elastase are thought to influence components of hemostasis, and furthermore provide an alternative pathway of fibrinolysis. Histological, experimental, and clinical data suggest that extravascular fibrinolysis, mediated both by the plasmin system and by proteases like neutrophil elastase, is a prominent finding in various diseases such as lung cancer, chronic inflammatory bowel disease, vasculitis and connective tissue disease, bacterial sepsis, and septic shock.
