IFNG and infection: Nevertheless, a considerable level of T. cruzi specific antibodies was detected in the group of animals primed with pVXVR-mIFN-γ plasmid alone, indicating that mice which have never seen T. cruzi antigen before but were stimulated with plasmid carrying IFN-γ posses the capacity to better respond, at least at the humoral level, to a subsequent virulent infection.
