Abstract：
:Toxoplasma gondii can activate the nucleotide-binding domain and leucine-rich repeat-containing proteins NLRP1/3 inflammasomes, which mediate host resistance to the infection. Here we showed that deletion of mitogen-activated protein kinases MAPK1 and MAPK2 of type I parasite decreases acute virulence in mice, characterized by low levels of interleukin (IL)-18, NLRP1/3, ASC, and caspase-1, and high levels of IL-10 and interferon (IFN)-β transcripts. Additionally, the mutants increased phosphorylation of STAT1, and decreased phosphorylation of STAT3. These findings suggest that MAPKs are associated with inflammasome activation in T. gondii-infected mice, which may contribute to new insight into the pathogenesis of T. gondii infection.
