Abstract

The respective roles of cell-mediated immunity and humoral immunity in host defence were investigated in mice infected with influenza A/PR8 virus. Transferred immune spleen cells were shown to provide full protection only when they were actually secreting antibody. Serum antibody transferred in ‘physiological’ amounts was found to be protective in immunologically intact or in immunosuppressed animals. The specificity of the transferred antibody was shown to be critical, since antibody to internal components of the virus was inefficient while antibody to haemagglutinin, especially that to the strain-specific determinants of the haemagglutinin molecule, was highly efficient.

摘要

在感染甲型/PR8流感病毒的小鼠中,研究了细胞介导免疫和体液免疫在宿主防御中的各自作用。已证明,只有当转移的免疫脾细胞实际分泌抗体时,它们才能提供完全保护。发现以“生理”量转移的血清抗体在免疫功能正常或免疫抑制的动物中具有保护作用。转移抗体的特异性被证明至关重要,因为针对病毒内部成分的抗体效率低下,而针对血凝素的抗体,尤其是针对血凝素分子菌株特异性决定簇的抗体,效率很高。
