为寻求丙型肝炎病毒基因免疫的最佳动物实验方法,探讨不同处理方式对重组体pCD-HCV1诱发Balb/c小鼠产生抗体的影响。采用分子生物学技术构建了HCV重组体,用不同免疫次数、途经、剂量和不同处理方式将其免疫小鼠。结果显示:重组体pCD-HCV1(100μg/只/次,n=12)经肌肉1次、2次、3次和4次免疫小鼠后,抗体水平分别为0.183±0.06,0.428±0.05,0.707±0.08(OD410值,下同),其中4次免疫组抗体水平最高;小鼠经灌胃、腹腔注射、皮下注射和肌肉注射(100μg/只×3次)不同途径分别免疫小鼠(n=6),抗体水平依次为0.138±0.05,0.178±0.07,0.233±0.08和0.691±0.05;以不同剂量(10μg,50μg,100μg)分别免疫鼠(n=8),抗体水平依次为0.110±0.09;0.330±0.04和0.700±0.07,各组间差异均有显著性意义(P<0.01);用普鲁卡因100μl(0.04mg)肌肉注射24h后,再肌肉、皮下注射pCD-HCV1,抗体水平比直接肌肉、皮下注射同剂量重组体明显增高。该研究结果为寻求HCV-DNA疫苗动物实验最佳免疫?
In order to find out the best animal experiment method for hepatitis C virus gene immunization, the effects of different treatment methods on antibody production in Balb / c mice induced by recombinant pCD-HCV1 were explored. Recombinant HCV was constructed by molecular biology techniques and immunized mice with different times of immunization, route of administration, dosage and different treatments. The results showed that the antibody levels of mice immunized once, twice, three times and four times with recombinant pCD-HCV1 (100μg / mouse / time, n = 12) were 0.183 ± 0.06,0 .428 ± 0.05,0.707 ± 0.08 (OD410 value, the same below), among which the antibody level in the four immunized groups was the highest; the mice were intragastrically, intraperitoneally, subcutaneously, and intramuscularly injected 3 times) were immunized by different ways (n = 6), the antibody levels followed by 0.138 ± 0.05,0.178 ± 0.07,0.233 ± 0.08 and 0.691 ± 0.05 (N = 8) were immunized with different doses (10μg, 50μg, 100μg). The antibody levels were 0.110 ± 0.09; 0.330 ± 0.04 and 0.700 ± 0.07, (P <0.01). After intramuscular injection of procaine 100μl (0.04mg) for 24h, Meat, subcutaneous injection of pCD-HCV1, antibody levels were significantly higher than the direct muscle, subcutaneous injection of the same dose of recombinant. The results of this study seek the best immune for HCV-DNA vaccine animal experiments?
