HCV peptide-specific T-cell lines grown from PBMC frozen pre-vaccination in HCV infected patients: (A) PBMC frozen pre-vaccination from HLA-A2+ patients who showed a positive response to NS31406 after vaccination were cultured with the 15mer (LAAKLSGLGINAVAY; optimal epitope highlighted in bold) peptide and recombinant human IL-2 for 19 days. PBMC were stained with MHC class I pentamer (NS31406 KLSGLGINAV) at day 0, 12, and 19 of the culture; and (B) example plots for the two patients for which NS31406-specific T-cells were grown to detectable levels at day 19 from pre-vaccine PBMC (patients 351, 357. Negative at day 19: patients 355 and 360).
