Abstract [en]

Monocytes induced to express tissue factor (TF), the initiator of the clotting cascade, might play an important role in the pathogenesis of atherosclerosis. We have investigated the TF-inducing capacity of two factors thought to be involved in atherogenesis, i.e. the platelet derived growth factor-BB (PDGF-BB) and monocyte chemotactic protein-1 (MCP-1), a member of the chemokine superfamily. PDGF-BB and MCP-1 are potent chemotactic and activating factors for human blood monocytes. alpha-thrombin which is known to induce TF in endothelial cells and that recently has been shown to induce secretion of MCP-1 from endothelial cells and monocytes was also studied. PDGF-BB induced a dose-dependent expression of TF-antigen in monocytes with maximal response at 20-50 ng/mL. At higher concentrations the expression was reduced. No synergistic effect between PDGF-BB and LPS was seen. MCP-1 also induced a dose-dependent TF-expression with maximal response at 50 ng/mL. In contrast to these results thrombin did not. MCP-1 had a slight, but not significant, priming effect on LPS-induced TF expression. These data show that PDGF-BB and MCP-1 are potent inducers of TF in human peripheral blood monocytes. We suggest that this TF-induction might be an important link between hemostasis and inflammation.
