Figure 6

Intracellular cytokine expression of IFNγ and IL-2 by CD4+ and CD8+ T cells eight weeks post-infection. Expression of IFNγ is shown in the top panels, IL-2 in the middle panels and dual expressing (IFNγ+IL-2+) in the bottom panels for CD4+ T cells (A) and CD8+ T cells (B). Individual data points are shown with mean expression indicated by a line for each data set. Significant differences in cytokine expression are indicated by a line over the applicable data sets and p-value indicated. Calculations were made using an unpaired t-test.
