Heat-killed pathogenic Leptospira interrogans serovar rachmati induced the production of gamma interferon (IFN-gamma) and the IFN-gamma-inducing cytokines interleukin-12p40 (IL-12p40) and tumor necrosis factor alpha in human whole blood in vitro. The production of IFN-gamma was largely dependent on IL-12. These data establish that pathogenic leptospires can stimulate the production of type I cytokines involved in cellular immunity.
热灭活的致病性问号钩端螺旋体赖型菌株在体外可诱导人全血产生γ干扰素(IFN-γ)以及诱导IFN-γ产生的细胞因子白细胞介素-12p40(IL-12p40)和肿瘤坏死因子α。IFN-γ的产生很大程度上依赖于IL-12。这些数据表明致病性钩端螺旋体能刺激参与细胞免疫的I型细胞因子的产生。
