摘要
目的趋化因子CXCL16可能在动脉粥样硬化形成中发挥重要作用,本文探讨贝特类调脂药物非诺贝特对动脉CXCL16表达的影响。方法研究对象采用载脂蛋白E基因敲除小鼠,随机分为非诺贝特组及对照组,非诺贝特干预8周后,比较两组间血脂、血清CXCL16水平;取小鼠主动脉采用医学图像分析系统测量动脉斑块大小,免疫组织化学半定量分析主动脉弓CXCL16及CXCR6的蛋白表达,实时PCR测定CXCL16mRNA。结果非诺贝特组动脉硬化程度较对照组减轻,斑块面积减小;非诺贝特组主动脉弓CXCL16和CXCR6的平均光密度值减低;非诺贝特组CXCL16mRNA表达较对照组减低(0.222±0.189比1.00±0.996,P<0.05)。结论非诺贝特可以改善载脂蛋白E基因敲除小鼠动脉粥样硬化形成,降低CXCL16及其受体CXCR6的蛋白表达,有效减低CX-CL16mRNA的表达,并且该作用独立于其调脂作用。
