摘要 腹主动脉瘤(AAA)指的是主动脉直径扩张50%以上的退行性疾病,近年来发病率呈上升趋势,动脉瘤一旦破裂,死亡风险极高.现有研究结果显示AAA的起始因素为炎性反应,中性粒细胞和单核细胞浸润腹主动脉壁外层和中层,释放炎性因子,激活基质金属蛋白酶(MMPs),导致细胞外基质(ECM),尤其是弹性纤维的降解;同时,中层的血管平滑肌细胞(VSMCs)发生功能改变,收缩功能降低,进一步使血管壁抗张力能力下降,动脉壁在动脉高压血的冲击下逐步扩张形成AAA.低密度脂蛋白受体相关蛋白1(LRP1)是一种具有多种功能的受体蛋白,参与了AAA发生机制的诸多方面,近年来受到广泛关注.本文就LRP1和AAA关系的研究进展进行综述.
