Although malaria is a serious disease caused by the protozoan genus Plasmodium, several reports have suggested that malaria could stimulate the host innate and adaptive immune systems to combat cancer [22–25] by stimulating IFN-γ production, activating natural killer (NK) cells, γ δ T cells, inducing the maturation of DCs and stimulating T-cell proliferation [24, 26]. Here, IFNG is linked to malaria.
