摘要 目的探讨CD40-CD40配体系统(CD40-CD40L)对不同因素致动脉粥样硬化形成的血浆黏附分子影响。方法 40只实验兔随机分为5组,每组8只。A组(正常对照组):普通颗粒饲料喂饲;B组(高脂模型组):高脂饲料喂饲;C组(高脂模型CD40阻断组):高脂饲料喂饲同时给予抗CD40配体抗体0.5ml(250μg),腹腔注射,每周两次;D组(免疫刺激组):应用肺炎衣原体感染制备动脉硬化模型;E组(免疫刺激CD40阻断组):制备模型的同时给予抗CD40配体抗体0.5ml(250μg),腹腔注射,每周两次;实验共16周。实验结束后,检查如下指标:①ELISA法检测sCD40L、sVCAM-1、sICAM-1。斑块/内膜面积比。16周末获取标本检测分析。结果 B、C、D、E组与A组比较sCD40LsVCAM-1、sICAM-1水平升高(P<0.01)。C、E组与B、D组比较sCD40L、sVCAM-1、sICAM-1水平降低(P<0.01)。结论通过高脂饮食、免疫刺激可引起实验兔sCD40L、sVCAM-1、sICAM-1水平升高,阻断CD40-CD40L,可降低实验兔sCD40L、sVCAM-1、sICAM-1水平,从而抑制炎症反应、延缓动脉粥样硬化进展。
