FIG. 7.
Postinfection analysis of SIV-specific T cell responses in r08019. We carried out an intracellular cytokine staining assay in PBMC from r08019 at week 3.4 PI. The stimuli consisted of pools of peptides spanning the entire Nef protein or three segments of the Gag polyprotein. A peptide corresponding to the Mamu-A*01-restricted Gag181–189CM9 epitope was included as well. Reactivity to each stimulus is shown based on the production of IFN-γ and/or TNF-α. CD8+ and CD4+ T lymphocytes are shown in the top and bottom rows, respectively.
