Injection of recombinant interleukin-6 (IL-6) into mice enhances recovery from infection with Listeria monocytogenes. In this study, the role of IL-6 during primary and secondary Listeria infection was further tested. Neutralization of IL-6 by polyclonal antibody exacerbated primary infection and significantly delayed gamma interferon production by cultured spleen cells. In contrast, administration of anti-IL-6 antibody at the time of secondary infection did not affect the recovery of mice from infection or gamma interferon production, showing that activated T cells are not dependent on IL-6.
向小鼠注射重组白细胞介素-6(IL-6)可增强其从单核细胞增生李斯特菌感染中恢复的能力。在本研究中,进一步检测了IL-6在原发性和继发性李斯特菌感染中的作用。用多克隆抗体中和IL-6会加重原发性感染,并显著延迟培养的脾细胞产生γ干扰素。相比之下,在继发性感染时给予抗IL-6抗体并不影响小鼠从感染中恢复或γ干扰素的产生,这表明活化的T细胞不依赖于IL-6。
