    摘要:

    [目的] 探讨猪瘟(CSF)、高致病性猪蓝耳病(HP-PRRS)、口蹄疫(FMD)3种疫苗不同免疫组合,对猪免疫机能及其相关细胞因子表达量的影响。[方法] 采用ELISA方法,检测猪血清中IL-1、IL-2、IFN-γ表达量的动态变化,分析免疫后3种细胞因子动态变化规律。[结果] 免疫后猪血清中的IL-1、IL-2、IFN-γ含量变化不一致。其中:IL-1表达量出现“波浪线”变化,且各试验组之间差异不显著;CSF、HP-PRRS、FMD 3种疫苗同步联合免疫组与对照组(C组)相比,二免后60 d和90 d的IL-2表达量差异显著;IFN-γ表达量呈现上升状态,3种疫苗同步联合免疫组与对照组(C组)相比,各时间点的IFN-γ表达量差异均显著(P<0.05),且维持在较高水平。[结论] CSF、HP-PRRS、FMD 3种疫苗不同免疫组合可引起猪免疫机能的变化,且对免疫机能的影响较为复杂;整个免疫过程中各细胞因子的变化不是单纯的上升和下降,而是一个动态的变化过程。

    Abstract:

    [Objective] To investigate the influence of three vaccine combinations of CSF,HP-PRRS and FMD on immune response and expression of some cytokines in swine serum. [Methods] The dynamic change of IL-1,IL-2 and IFN-γ expression in swine serum were tested by ELISA. The dynamic change rule of the three kinds of cytokines after immunization were analyzed. [Results] The change trends of IL-1,IL-2 and IFN–γ content in swine serum after immunization were not the same. A “wave”trend was appeared in the expression of IL-1,and there was no significant difference between different groups. IL-2 change trend was not consistent with different groups,combined with the group immunized by CSF,HP–PRRS and FMD vaccine,compared with the control group(group C). The expression of IL-2 was significantly different at 60 d and 90 d after second immunization;Compared with group C,the expression of IFN–γ in the group immunized by CSF,HP–PRRS and FMD vaccine was increasing. Expressions of IFN –γ were significantly different at each time point(P <0.05),and was always at a high level. [Conclusion] Different immune combinations of CSF,HP-PRRS and FMD vaccine may cause different immune responses to swine,and the changes of cytokines throughout the immune process were not simply rising and falling,but a relatively complex dynamic change process.
