In contrast, the FMLQILDFYTKVYE epitope, generated a high IFN-γ/IL-10 ratio before infection in the saline-treated controls but promoted the most reduced IFN-γ/IL-10 ratios after infection, and TNF-α/IL-10 ratios before and after infection, which are indicative of its potential ability to induce a T cell regulatory response (Figure 6). This evidence concerns the gene IFNG and infection.
