Additionally, the HLA-A*02:01-restricted Ebola virus epitope peptide LLADGLAKA (validated in prior studies) [25] and the HLA-A*11:01-restricted influenza epitope peptide QTNAMVTLR [26] were reciprocally used as irrelevant negative controls for the HLA-A*11:01 and HLA-A*02:01-restricted predicted influenza epitopes, respectively. Here, HLA-A is linked to influenza.
