Role of Interleukin-10 in Malaria: Focusing on Coinfection with Lethal and Nonlethal Murine Malaria Parasites

[摘要] Interleukin- (IL-) 10, anti-inflammatory cytokine, is known to inhibit the protective immune responses against malaria parasites and to be involved in exacerbating parasitemia duringPlasmodiuminfection. In contrast, IL-10 is regarded as necessary for suppressing severe pathology duringPlasmodiuminfection. Here, we summarize the role of IL-10 during murine malaria infection, focusing especially on coinfection with lethal and nonlethal strains of malaria parasites. Recent studies have demonstrated that the major sources of IL-10 are subpopulations of CD4+T cells in humans and mice infected withPlasmodium. We also discuss the influence of innate immunity on the induction of CD4+T cells during murine malaria coinfection.
