摘  要:
利用国内首次克隆成功的鸡 IL- 2基因真核表达质粒与新城疫病毒 (NDV) D2 6株 F基因真核质粒 (F基因疫苗 )联合免疫 SPF雏鸡 ,观察了其诱导的免疫应答及免疫保护作用 ,以及不同免疫方式对其免疫作用的影响。结果证实了国内克隆鸡 IL- 2基因的免疫增强作用 ,以及作为免疫佐剂应用于禽类基因免疫的可行性 ,为鸡 IL- 2这一新型佐剂的实际应用提供了重要的试验依据。

摘  要:
To investigate the effect of cloned chicken IL 2 gene on the NDV gene vaccination,SPF chickens were innoculated with F protein expression plasmid and chicken IL 2 expression plasmid in different ways,one is coinjection,the other is separate injection.Antibody and T、B cell responses showed that the humoral and cellular immunity of F and IL 2 plasmid vaccinated chickens significantly enhanced as compared with those vaccinated with F protein expression plasmid alone.Six weeks later,All chickens were challenged with a lethal dose of NDV F 48 E 9 strain,40% chickens vaccinated by separate injection of two plasmids survived,50% chickens vaccinated by coinjection survived.The enhanced immunity by adding IL 2 plasmid showed that IL 2 was expressed,and it really has adjuvant effect,the effect of IL 2 expressing plasmid was dependent on coinjection with the plasmid expressing antigen.
