Plasmids encoding the measles virus hemagglutinin (HA) and nucleoprotein (NP) proteins inoculated into the skin of BALB/c mice by the gene gun method induced both humoral and cytotoxic lymphocyte class I-restricted immune responses. Although intramuscular immunization induces the immunoglobulin G2a (IgG2a) antibody isotype for both antigens, with gene gun immunization, the NP still generated mainly IgG2a and the major isotype induced by the HA was IgG1. Interestingly, gene gun coimmunization of HA and NP plasmids resulted in a dominant IgG1 HA response and the switching of antibodies generated against the NP to the IgG1 isotype.
通过基因枪方法将编码麻疹病毒血凝素(HA)和核蛋白(NP)蛋白的质粒接种到BALB/c小鼠皮肤中,可诱导体液免疫和细胞毒性淋巴细胞I类限制性免疫反应。尽管肌肉内免疫可诱导针对两种抗原的免疫球蛋白G2a(IgG2a)抗体亚型,但通过基因枪免疫,NP仍主要产生IgG2a,而HA诱导的主要抗体亚型是IgG1。有趣的是,HA和NP质粒的基因枪共免疫导致了占主导地位的IgG1 HA反应,并且针对NP产生的抗体转换为IgG1亚型。
