摘要
目的对以酵母为载体所制得的艾滋病候选疫苗进行研究。方法构建表达Gag及IL-2的质粒载体,将表达载体分别转化入酵母细胞,通过酵母杂交获得同时表达两种基因的酵母杂交体,放大培养后经灭活、分装、冻干,制得细胞干粉作为试验的疫苗。用小鼠及食蟹猴对试验疫苗进行有效性及安全性研究。结果杂交酵母可以稳定表达Gag及IL-2;经皮下注射可以分别在小鼠及食蟹猴体内诱导一定水平的细胞免疫反应;对小鼠肿瘤模型的研究表明,疫苗可以诱导有效的免疫保护反应;疫苗的安全性良好,没有明显的毒副作用,只在注射部位引起轻微的红肿,个别动物有低热反应,但均在一周左右恢复正常。结论杂交酵母艾滋病疫苗具有诱导细胞免疫反应的能力;杂交酵母载体疫苗在相关疾病的治疗方面有良好的应用前景。
