Cytokine mRNA levels were assessed in Burkholderia pseudomallei-susceptible BALB/c mice and B. pseudomallei-resistant C57BL/6 mice following administration of a sublethal dose of less virulent (LV) B. pseudomallei, a candidate immunogen tested for protection against a highly virulent (HV) challenge. Compared on the basis of the bacterial loads, the cytokine patterns induced by HV and LV B. pseudomallei were similar, involving gamma interferon, interleukin-10, and other cytokines. Partial cross-protection between B. pseudomallei strains is shown to be associated with cytokine profiles involving both type 1 and type 2 cytokines.
在给予亚致死剂量的低毒力(LV)类鼻疽伯克霍尔德菌(一种经测试用于预防高毒力(HV)攻击的候选免疫原)后,评估了对类鼻疽伯克霍尔德菌敏感的BALB/c小鼠和对类鼻疽伯克霍尔德菌有抗性的C57BL/6小鼠体内细胞因子mRNA水平。基于细菌载量进行比较,HV和LV类鼻疽伯克霍尔德菌诱导的细胞因子模式相似,涉及γ干扰素、白细胞介素-10和其他细胞因子。结果表明,类鼻疽伯克霍尔德菌菌株之间的部分交叉保护与涉及1型和2型细胞因子的细胞因子谱有关。
