Perimental model. IFN–mediated immune responses are important for controlling tachyzoite proliferation through both acute acquired infection and reactivation of infection in the brain [37], and IFN has also been demonstrated to regulate the T. gondii load and interconversion inside the eye [38]. On the other hand, there have been enhanced IFN- mRNA expressions in each livers and spleens in mice treated with C48/80 within this study, thus, the inability to handle T. gondii replication observed in mice treated with C48/80 seems not to be a consequence of an increase in the expression of IFN-. IL-4 is protective against development of TE by preventing formation of T. gondii cysts and proliferation of tachyzoites in the brain [39]. Within this study, there had been drastically decreased levels of IL-4 and IL-10 in spleen and liver, respectively, from mice treated with C48/80. It has been reported that IL-10 limits parasite burden in murinePLOS One | www.plosone.orgMast Cells Modulate Acute ToxoplasmosisFigure 7. The liver histological evaluation of T. gondii-infected mice from distinctive groups. Infected mice i.p. inoculated with 102 RH tachyzoites of T. gondii had been killed at 9-10 days p.i.

This acquiring suggests that mediators released by C48/80-treated MCs outcome in impairment of T. gondii clearance, which could be related for the decreased IL-4 or IL-10 levels; whereas infected mice treated with DSCG result in reduced parasite burden, which could be associated to the improved IL-4 and IL-10 levels within this model. Our data indicated that MC activation is very important in the regulation from the inflammatory response to host defense against T. gondii infection, plus the cellular immune response might be partially impaired in infected mice treated with C48/80, that is crucial for the destruction and elimination of T. gondii. We can’t outline the mechanism increasing the parasite burden in acute toxoplasmosis with C48/80 treatment inside the present study; nevertheless, the fact that it requires MCs degranulation brings new aspect with the trouble. In addit.
