Injection of type 6b pneumococci into pigs results in a sharp rise in levels of interleukin-6 (IL-6) in blood, with an average peak value of 7,700 U/ml at 4 h and mortality in five of seven of these animals. Pretreatment at -24 h with the monocyte activator MTP-PE prevents this strong increase in IL-6 (peak value, 1,000 U/ml) and reduces mortality to zero of six animals. This suggests that MTP-PE, in addition to activating monocytes, protects animals by preventing the harmful increase of cytokines such as IL-6.
将6b型肺炎球菌注射到猪体内会导致血液中白细胞介素-6(IL-6)水平急剧上升,4小时时平均峰值为7700 U/ml,这些动物中有7只死亡5只。在-24小时用单核细胞激活剂MTP-PE进行预处理可防止IL-6的这种强烈升高(峰值为1000 U/ml),并将6只动物的死亡率降至零。这表明MTP-PE除了激活单核细胞外,还通过防止细胞因子如IL-6的有害增加来保护动物。
