Recent studies have established the importance of neutrophils in innate resistance to Listeria monocytogenes infection in mice. The purpose of this study was to determine the importance of neutrophils in acquired resistance to L. monocytogenes infection. Previously immunized mice that were depleted of neutrophils by administration of the antigranulocyte monoclonal antibody RB6-8C5 demonstrated less resistance to L. monocytogenes challenge than did nonimmunized control mice. In contrast, immunized control mice exhibited a heightened resistance to rechallenge, as expected. These results suggest that neutrophils make previously unrecognized contributions to acquired immunity to a facultative intracellular pathogen.
最近的研究证实了中性粒细胞在小鼠对单核细胞增生李斯特菌感染的天然抵抗力中的重要性。本研究的目的是确定中性粒细胞在对单核细胞增生李斯特菌感染的获得性抵抗力中的重要性。通过给予抗粒细胞单克隆抗体RB6-8C5使中性粒细胞耗竭的先前免疫小鼠,与未免疫的对照小鼠相比,对单核细胞增生李斯特菌攻击的抵抗力更低。相比之下,免疫对照小鼠如预期的那样对再次攻击表现出增强的抵抗力。这些结果表明,中性粒细胞对兼性细胞内病原体的获得性免疫做出了先前未被认识到的贡献。
