Defined candidate human vaccines for treating infection by Yersinia pestis, the agent of plague, have been developed. To facilitate evaluation of the vaccines' efficacy, the in vitro caspase-3 assay for cytotoxicity-neutralizing activity was modified and reevaluated. Immune serum-mediated caspase-3 neutralizing activity correlated with protection against infection in a nonhuman primate vaccine model of plague immunity.
已经开发出了确定的用于治疗由鼠疫杆菌(鼠疫的病原体)引起的感染的候选人类疫苗。为便于评估疫苗的效力,对用于检测细胞毒性中和活性的体外半胱天冬酶-3检测方法进行了改进和重新评估。在鼠疫免疫的非人灵长类动物疫苗模型中,免疫血清介导的半胱天冬酶-3中和活性与抗感染保护作用相关。
