| abstractText | OBJECTIVE: The contribution of thrombosis and coagulation in atherogenesis is largely unknown. We investigated the contribution of the coagulation intrinsic factor VIII (FVIII)-dependent pathway in atherogenesis. METHODS AND RESULTS: Apolipoprotein E and FVIII double-deficient mice (E degrees/FVIII degrees) were generated. Aortic root lesions were analyzed in 14-week-old and 22-week-old female mice maintained for 8 or 16 weeks, respectively, on a normal chow diet or a hypercholesterolemic diet. CONCLUSIONS: Despite a higher plasma total cholesterol concentration compared with E degrees mice, E degrees/FVIII degrees mice developed dramatically less early-stage atherosclerotic lesions. Whereas early lesions in E degrees mice contained abundant fibrin(ogen) deposits on which few platelets adhered, lesions in E degrees/FVIII degrees were almost devoid of fibrin(ogen), and no platelets could be detected. The genotype effect on development and composition of lesions tended to decrease with time. This study demonstrates that the activation of the intrinsic pathway of coagulation is potently proatherogenic at the early stage of atherogenesis. |
