HC078/VID 417—definition of CD4⁺ T-cell epitopes in HIV-1 protein Pol. PBMC of subject 417 were expanded by HC078 and stimulated with truncated peptides (left) in ICS. IFN-γ (green) and TNF-α (orange) producing CD4⁺ T cells were determined. Arrows in the graphs and amino acids V and P indicate the stimulatory peptide termini.
