Here, among the members of a healthy population presumed to have previously been infected by pandemic H1N1 (pH1N1), we found that pH1N1-specific T cells showed crossbut biased reactivity to human-infecting AIVs, i.e., H5N1, H6N1, H7N9, and H9N2, which correlates with distinct protections. Thus, to investigate the contribution of different cellular antigens of influenza viruses to biased cross-T-cell reactivities, we compared T-cell responses to H7N9 and pH1N1 among the members of the healthy population using overlapping peptides covering the M1 and NP proteins. Further analysis indicated that these peptides contained previously identified HLA class I-or class II-restricted epitopes (see Fig. S2D and H) and that the immunogenicity can be influenced by the substitutions in different AIVs.
