摘要：
The effects of glycoprotein (GP) Ⅱb/Ⅲa inhibitors on the development of the atherosclerotic process has received scant attention. To investigate whether GP Ⅱb/Ⅲa blockade influences atherosclerosis lesion and HMGB-1/TLR4 signaling, we compared plaque formation in ApoE~(-/-) mice: control group (n=10); IgG group (n=10, 50 μg) and GP Ⅱb/Ⅲa mAb group (n=10, 50 μg). All mice were fed on a Western diet (10% fat and 1.25% cholesterol) for 10 weeks. GP Ⅱb/Ⅲa blockade significantly decreased the atherosclerotic lesion and platelet adhesion to the vessel wall. Immunohistochemistry analysis showed that blocking GP Ⅱb/Ⅲa diminished MOMA-2 and VCAM-1 expression in aortic plaque in ApoE~(-/-) mice. Western blot results indicated that HMGB-1, TLR4, and NF-κB levels were markedly reduced in arteries of ApoE-/- mice treated with GP Ⅱb/Ⅲa mAb (P < 0.05). Moreover, GP Ⅱb/Ⅲa mAb decreased plasma HMGB-1, IL-1β, TNF-α and MCP-1 concentrations. Our findings demonstrated that GP Ⅱb/Ⅲa mAb significantly decreased atherosclerotic lesions and HMGB-1, TLR4 and NF-κB expression in ApoE~(-/-) mice (P < 0.05). The present study has suggested a possibility that GP Ⅱb/Ⅲa blockade attenuates atherosclerosis by inhibiting the HMGB-1/TLR4 pathway..
