PG - 1695-1701 LID - 12541 [pii] AB - OBJECTIVE: Deep vein thrombosis (DVT) is one common vascular complication after trauma or surgery. Macrophage plays an important role in recanalization of thrombosis and monocyte chemotactic protein 1 (MCP-1) has a potent chemotactic role for macrophage. This study investigated the role of MCP-1 and macrophage in DVT thrombolysis. MATERIALS AND METHODS: DVT mice model was established for evaluating thrombosis grades, and divided into DVT, DVT + MCP-1 recombinant protein, and DVT + MCP-1 neutralizing antibody groups. MCP-1 mRNA and protein expression, weight/length ratio of thrombosis were tested at 1, 5, 9 and 15 day after DVT. F4/80 protein expression in thrombosis on day 9 was measured to reflect infiltration of macrophage. RESULTS: DVT model mice had thrombosis grade at 2.47 +/- 0.22 whilst no thrombosis occurred in sham group. DVT group had gradually increased MCP-1 mRNA and protein expression, which reached the peak at day 9, followed by decreased expression. Thrombosis weight/length ratio showed decreasing trends. MCP-1 protein injection significantly elevated MCP-1 expression, decreased thrombosis weight/length ratio, and elevated macrophage infiltration. Injection of MCP-1 antibody remarkably decreased MCP-1 expression, elevated thrombosis weight/length ratio and macrophage infiltration. CONCLUSIONS: MCP-1 up-regulation participates in macrophage chemotaxis and thrombolysis after DVT formation. The blockade of MCP-1 weakens its thrombolysis effects.
