Francisella tularensis can cause fatal respiratory tularemia in humans and animals and is increasingly being isolated in the United States and several European countries. The correlates of protective immunity against this intracellular bacterium are not known, and currently there are no licensed vaccines available for human use. Cell-mediated immunity has long been believed to be critical for protection, and the importance of humoral immunity is also now recognized. Furthermore, synergy between antibodies, T cell-derived cytokines, and phagocytes appears to be critical to achieve sterilizing immunity against F. tularensis. Thus, novel vaccine approaches should be designed to induce robust antibody and cell-mediated immune responses to this pathogen.
土拉弗朗西斯菌可导致人类和动物发生致命的呼吸道兔热病,在美国和几个欧洲国家越来越多地被分离出来。针对这种细胞内细菌的保护性免疫相关因素尚不清楚,目前尚无获批用于人类的疫苗。长期以来,细胞介导的免疫一直被认为对保护至关重要,体液免疫的重要性现在也得到了认可。此外,抗体、T细胞衍生的细胞因子和吞噬细胞之间的协同作用似乎对于实现针对土拉弗朗西斯菌的杀菌免疫至关重要。因此,应设计新的疫苗方法来诱导针对这种病原体的强大抗体和细胞介导的免疫反应。
