FACS analysis of HIV-specific tetramer+ and IFN-γ+ T cells.
FACS data from individual 433. Similar tetramer staining and differential IFN-γ production after stimulation with 1 μg peptide/mL for samples drawn early and late in HIV infection. Positive (PMA/ionomycin-stimulated T cells) and negative (no stimulus) controls for IFN-γ production are shown for one time point.
