摘要 目的探讨多房棘球绦虫(Em)重组BCG-EmⅡ/3疫苗免疫和Em原头节攻击后小鼠脾细胞因子的变化。方法将Balb/c小鼠按体质量随机分为3组:疫苗皮下注射组、疫苗鼻腔内接种组、对照组。免疫后8周用Em原头节进行攻击感染,感染后18周杀鼠取脾,分离脾细胞,分别用原液、Em抗原(EmAg)、刀豆蛋白A(ConA)或植物血凝素(PHA)培养,酶联免疫吸附(ELISA)法检测脾细胞培养上清液中白细胞介素2(IL-2)、1干扰素(IFN-γ)、肿瘤坏死因子α(TNF-α)、白细胞介素4(IL-4)水平。结果疫苗皮下注射组原液培养条件下IL-2、IFN-γ、TNF-α和IL-4水平分别为(34.6±2.7)、(34.5±2.8)、(265.0±0.0)、(9.8±2.6)ng/L,与对照组[(25.0±1.9)、(30.0±0.0)、(10.0±0.0)、(12.5±2.7)ng/L]比较差异均有统计学意义(P〈0.01或〈0.05);疫苗鼻腔内接种组原液培养条件下上述4种指标分别为(32.5±2.2)、(33.6±2.7)、(130.0±0.0)、(10.4±2.7)ng/L,与对照组比较差异均有统计学意义(P〈0.01或〈0.05);疫苗皮下注射组原液培养条件下TNF-α水平明显高于疫苗鼻腔内接种组(P〈0.01)。EmAg、ConA(或PHA)刺激培养条件下,上述4种指标明显高于相同组别的原液培养(P〈0.01),且ConA(或PHA)刺激培养条件下,上述4种指标明显高于相同组别的EmAg刺激培养条件(P〈0.01)。结论多房棘球绦虫重组BCG-EmⅡ/3疫苗诱导小鼠产生辅助T淋巴细胞(Th)1型免疫反应,从而对抗Em原头节攻击感染。 Objective To investigate the changes of cytokines of splenocytes in mice immunized with recombinant BCG-Em Ⅱ/3 vaccine of Echinococcus multilocularis(Em)and consequently ,challenged with Em protoscoleces. Methods Balb/c mice were subcutaneously or intranasally vaccinated and challenged with Em protoscoleces on the 8^th week of vaccination. After they were killed on the 18^th week of infection, their splenocytes were separated and cultured with EmAg, ConA or PHA, respectively. The supernatants were gathered to measure the levels of IL-2, IFN-γ, TNF-α and IL-4 by ELISA Kits. Results The levels of IL-2, IFN-γ, TNF-α and IL-4 in the subcutaneous group were(34.6 ± 2.7), (34.5 ± 2.8), (265.0 ± 0.0) and (9.8 ± 2.6)ng/L respectively; those in the intranasal group were (32.5 ± 2.2), (33.6 ± 2.7), (130.0 ± 0.0) and (10.4 ±2.7)ng/L respectively; those in the control were (25.0 ± 1.9),(30.0 ±0.0),(10.0 ±0.0) and (12.5 ± 2.7)ng/L, respectively; there were statistical differences between the immunized groups and control group(P 〈 0.01 or 〈 0.05 ) ; The level of TNF-α in the subcutaneous group was higher than that in the intranasal group. Conclusion Th1 response has been induced in mice vaccinated with rBCG-Em Ⅱ/3 vaccine and challenged with Em protoscoleces.
