Abstract
Preexisting T-cell immunity directed at conserved viral regions promotes enhanced recovery from influenza virus infections, with there being some evidence of cross-protection directed at variable peptides. Strikingly, many of the immunogenic peptides derived from the current pandemic A(H1N1)-2009 influenza virus are representative of the catastrophic 1918 "Spanish flu" rather than more recent "seasonal" strains. We present immunological and structural analyses of cross-reactive CD8(+) T-cell-mediated immunity directed at a variable (although highly cross-reactive) immunodominant NP(418-426) peptide that binds to a large B7 family (HLA-B*3501/03/0702) found throughout human populations.
