Identification and Relative Abundance of Naturally Presented and Cross-Reactive Influenza a Virus MHC Class I-restricted T Cell Epitopes

Using an immunopeptidomics approach, naturally presented influenza A virus-derived ligands restricted to HLA-A*24:02, HLA-A*68:01, HLA-B*07:02, and HLA-B*51:01 molecules were identified.
