Abstract
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.
