The role of the monocyte in the generation and dissolution of arterial and venous thrombi.
Monocyte infiltration into forming thrombus has been demonstrated in experimental models of venous thrombosis developed in our laboratories. These cells produce and release plasminogen activators as the thrombus organises and resolves. Monocytes are also capable of assembling and releasing procoagulant factors and the evidence for their importance in thrombogenesis is reviewed. The ability of monocytes to maintain this fibrinolytic balance suggests that they may have a role in both thrombosis and thrombus resolution. Control of the mechanisms which regulate these activities may therefore be important in preventing thrombus formation or stimulating its resolution.
