小鼠对利什曼原虫的易感性与NK细胞介导的先天免疫反应不足有关。我们分析了NK细胞激活趋化因子在耐药和易感小鼠感染的第一天在体内的表达。感染1 d后,C57BL/6耐药小鼠引流淋巴结中γ干扰素诱导蛋白10 (IP-10)、单核细胞趋化蛋白1 (MCP-1)和淋巴趋化蛋白mRNA表达上调,而BALB/c易感小鼠则无上调。在感染后不久,用重组IP-10局部处理BALB/c小鼠,导致引流淋巴结NK细胞活性增强。数据表明,虽然NK细胞的募集在易感小鼠中是正常的,但缺乏NK细胞激活趋化因子是导致NK细胞介导的防御不理想的一个因素。
ABSTRACT Susceptibility of mice to Leishmania major is associated with an insufficient NK cell-mediated innate immune response. We analyzed the expression of NK cell-activating chemokines in vivo during the first days of infection in resistant and susceptible mice. The mRNA expression of gamma interferon-inducible protein 10 (IP-10), monocyte chemoattractant protein 1 (MCP-1), and lymphotactin was upregulated 1 day after infection in the draining lymph nodes of resistant C57BL/6 mice but not in those of susceptible BALB/c mice. In vivo local treatment of BALB/c mice with recombinant IP-10 shortly after infection resulted in an enhanced NK cell activity in the draining lymph node. The data suggest that although the recruitment of NK cells is normal in susceptible mice, the lack of NK cell-activating chemokines is a factor resulting in a suboptimal NK cell-mediated defense.
