在易致动脉粥样硬化的小鼠使用C1酯酶抑制剂阻止动脉损伤后的新生内膜形成

背景：尽管在人类动脉粥样硬化（AS）形成中有补体系统的参与，但是在动脉损伤后的重塑过程中补体的作用尚不清楚。我们在ApoE-/-小鼠使用C1-酯酶抑制剂，探讨补体级联对新生内膜形成的影响。方法和结果：给ApoE-/-小鼠喂饲致AS饮食，并以导丝诱导颈动脉内皮剥脱模型，再于围术期给予C1-酯酶抑制剂（Berinert;15IUi.v.）或赋形剂，随之每2天给一次。通过检测血浆C1-酯酶抑制剂活性来证实治疗效果。结果发现在C1-酯酶抑制剂处理的小鼠，血清甘油三酯显著减少，而胆固醇水平无显著改变。三周后，C1-酯酶抑制剂处理小鼠的新生内膜面积显著下降，而中膜面积无显著改变。这些改变与新生内膜、中膜巨噬细胞和CD3+T细胞含量减少有关。RT-PCR检测显示，C1-酯酶抑制剂处理的小鼠损伤后10天的斑块中，C3mRNA表达显著下降；且ELISA法也证实损伤后C3的血清峰值显著下降；免疫化学揭示在斑块的巨噬细胞中C3和C3c共存且有强表达，而在C1-酯酶抑制剂处理的小鼠则显著下降。在离体流动条件下，C1-酯酶抑制剂削弱单核细胞停顿于激活的内皮和血小板，并在体阻止白细胞向损伤后一天的颈动脉募集。结论：C1-酯酶抑制剂限制新生内膜形成和炎症反应，这可能与补体的激活、白细胞募集被阻止以及甘油三酯下降有关，从而提供另一种治疗动脉疾病的方法。
