T-cell responses to 15-mer peptide pairs in Gag Pool 3. a The responses to individual pairs of 15-mer peptides in Gag Pool 3. Responses to peptide pairs in 53 responders to Pool 3 were analyzed by an IFN-γ ELISPOT assay. The dotted line at 200 SFU/106 CD8+ T cells indicates a threshold for a positive response. b Summary of responders and peptide pairs. Reported epitopes included in the pair of the 15-mer peptides are shown according to the LANL-HSD. HLA+ responders are those with the matching restricting HLA allele for the reported epitope
