HLA-A*0101-restricted influenza recall responses from human donors. Human donor X757 (A), donor X1257 (B) and donor X716 (C). CD8+ T cells were purified for IFN-γ ELISPOT assays from normal human donors. The experimental values are expressed as the mean IFN-γ net SFC/106 CD8+ T cell lymphocytes ± SEM for each peptide; tests were completed using triplicate wells. Significant responses from the indicated epitopes were defined as responses > than mean of background responses + (2.0 × Std. Dev.). Background responses were determined using supertype binding peptides from pathogens to which donors were not exposed, i.e., HIV, HCV and Plasmodium falciparum.
