Figure 7From: Human immunodeficiency virus type I-specific CD8+T cell subset abnormalities in chronic infection persist through effective antiretroviral therapy Frequency of HIV-specific CD8 + T cells producing IL-2 in chronically infected individuals with ongoing HIV replication either detectable (◆) or suppressed below detectable levels (●). The total number of HIV-specific CD8+ T cells producing IL-2/106 PBMC in response to Gag, Pol, Env and Nef peptide pools is shown for each individual at 4 serial time points with horizontal line through the group representing the median frequency.Back to article page
