Four plasmids encoding different C terminally and N terminally truncated pertussis toxin S1 subunits of Bordetella pertussis were constructed and tested for inducibility of protection against pertussis toxin in mice after DNA-based immunization. The region encoding an N-terminal 180-amino-acid fragment of the S1 subunit had the most potent ability to induce protective immunity.
构建了四种编码不同C端和N端截短的百日咳博德特氏菌百日咳毒素S1亚基的质粒,并在基于DNA免疫后测试了其诱导小鼠抵抗百日咳毒素的保护能力。编码S1亚基N端180个氨基酸片段的区域诱导保护性免疫的能力最强。
