百日咳杆菌合成AB5型外毒素Pertussis toxin(PT)。PT主要由蛋白质组成,可以引起百日咳。
体外:PT对先天性免疫应答显效。PT对人单核细胞源树突状细胞(MDDC)的效应,包括成熟,由cAMP所调节[1]。
体内:在NIH小鼠或BALB/c小鼠离体气管中,PT不影响其舒张与收缩功能,但显著地减少氯化钾或缓解去甲肾上腺素诱导的最大气管收缩。在雄性Wistar大鼠离体肠系膜阻力性小动脉血管中,PT降低其对去甲肾上腺素的敏感性[2]。
临床试验:PT是一种无细胞百日咳疫苗,用于增强年轻人和老年人免疫力,以减少社区传染并增强保护。受感染的老年人常无症状。无细胞百日咳疫苗改善百日咳症状,同时也作用于轻度以及无症状感染。此外,在婴儿群体中,无细胞百日咳疫苗可以显著降低传染率[3]。
