摘 要:
使用伊氏锥虫可溶性抗原免疫小鼠,研究了同时注射重组牛白细胞介素-2(rBIL-2)对NK细胞杀伤活性及特异性抗体水平的影响。试验鼠随机分为4组:Ag组,rBIL-2组,Ag+rBIL-2组和PBS对照组。以LDH释放法和间接ELISA法分别检测脾NK细胞杀伤活性及抗体水平。结果表明,首次免疫后24d,Ag组NK细胞杀伤活性为31.6%,rBIL-2组为99.66%,Ag+rBIL-2组为98.98%,对照组为19.73%;抗体效价Ag组为24,Ag+rBIL-2组为26。说明rBIL-2可显著提高NK细胞杀伤活性及促进抗体生成,提高宿主免疫力。

摘 要:
The effects of recombinant bovine interleukin 2 on NK cell activity and specific antibody level of mice immunized with soluble antigen of Trypanosoma evansi were studied.Thirty six mice were randomly divided into 4 groups and immunized or inoculated with soluble antigen of T.evansi,rBIL 2,antigen plus rBIL 2,and PBS.respectively.NK cell activity and specific antibody level of experimental mice were assaied respectively with LDH release assay and indirect ELISA.The activity of NK cells of Ag group was 31 6%,rBIL 2 group was 99 66%,Ag+rBIL 2 group was 98 98%,and PBS group was 19 73% 24 days after first immunization. Meanwhile,the specific antibody level of Ag group was 2 4,and the Ag+rBIL 2 group reached to 2 6.These results were indicated that rBIL 2 could significantly enhance NK cell activity and increase specific antibody level in vivo,and so that enforce the immunity of immunized animals.
