Abstract

We examined the effect of IL-12 and IL-18 on bactericidal activities of mouse peritoneal cell (PC) against Mycobacterium leprae (M. leprae). We demonstrated that IL-12 and IL-18 synergistically induced the NO-dependent bactericidal activity of PC by stimulating Natural Killer (NK) cells and T-cells through IFN-γ production. IL-12 and IL-18 induced host cell death through NK-cells and T-cells. Therefore, IL-12 and IL-18 play an important role on direct killing of intracellular M. leprae and on indirect killing of them through inducing host cell death.
