Figure 8.

Intracellular IFN-γ and IL-2 expression by CD4+ or CD8+ T cells. PBMC from monkey R immunized with CSLAM/PBS, collected at preimmunization and 4 weeks post virus boost time points, were assayed against PfSSP2/TRAP, or PfLSA1 peptide pools by intracellular cytokine staining. Data represent the percentage of CD4+ or CD8+ IFN-γ and IL-2 producing T cells. Note differences in the y-axis scales between CD4+ and CD8+ responses.
