摘要
目的:研究抗动脉粥样硬化疫苗的免疫学效应。方法:将含有胆固醇酯转运蛋白(CETP)羧基端26肽表位的蛋白疫苗免疫新西兰大白兔,测定兔血清中抗CETP抗体的产生情况及变化趋势,血脂中总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)的含量以及动脉粥样硬化斑块的大小。结果:疫苗诱导新西兰大白兔体内产生了高水平的抗CETP抗体,显著降低了TC、TG及LDL-C的含量,减少了动脉粥样硬化斑块的面积。结论:疫苗具备了较好的免疫学效应,为其作为抗动脉粥样硬化疫苗研究奠定了基础。
AIM:To study the immunological effect of antiatherosclerosis vaccine. METHOD: New Zealand white rabbits were immunized intramuscularly with protein containing 26-amino-acid of carboxyl terminal of cholesterol ester transfer protein (CETP). Anti-CETP antibodies in serum of rabbits were determined by ELISA, total cholesterol(TC) triglycerides(TG), high density lipoproteins cholesterol (HDL-C) and low density lipoproteins cholesterol (LDL-C) in serum of rabbits were determined, and patch area in aorta of rabbits were calculated by MapInfor 7.0 software. RESULT: High level anti-CETP antibodies were evoked in New Zealand white rabbits by vaccine. TC, TG and LDL-C in serum of rabbits were remarkably decreased and patch area in aorta of rabbits were reduced. CONCLUSION: Better immunological effect was evoked in rabbits by protein. The protein might be further developed as a vaccine against atherosclerosis.
