IFNG and infection: Supplementary Figure 3 shows the gating strategies and FMO controls. The frequency of IFN-γ-producing CD4+ and CD8+ T cells was analyzed both at the initial (Figure 5A), and at the late phase of the infection (Figure 5B). We detected a statistically significant higher production of FN-γ-producing only for CD4+ T cells stimulated with SLA at the final phase of the infection.
