Abstract

Maternal immunization of mice with formalin inactivated respiratory syncytial virus (FI-RSV) resulted in the passive transfer of RSV antibodies but not cellular components to the offspring. The offspring born to FI-RSV immunized mothers showed serum RSV neutralizing activity, effectively controlled lung viral loads without vaccine-enhanced disease, did not induce pulmonary eosinophilia, and cytokine producing cells after live RSV infection. Therefore, this study provides evidence that maternal immunization provides an in vivo model in investigating the roles of antibodies independent of cellular components.

摘要

用福尔马林灭活呼吸道合胞病毒(FI-RSV)对小鼠进行母体免疫,可导致RSV抗体而非细胞成分被动转移给后代。FI-RSV免疫的母亲所生的后代表现出血清RSV中和活性,有效控制肺部病毒载量且无疫苗增强疾病,不诱导肺部嗜酸性粒细胞增多,也不诱导活RSV感染后的细胞因子产生细胞。因此,本研究提供了证据表明母体免疫为研究抗体独立于细胞成分的作用提供了一种体内模型。
