HLA-A24, -B7, -DR2, -DR3, and -DR4 restriction of 54 peptides of influenza proteins M1, NP, PA, PB1, and PB2 that contain conserved sequences of 9 or more amino acids.

*Conserved aa are boldface. Consecutive peptides overlapping by 11 aa are aligned.
#Numbers are representative average IFN-γ spots forming cells per million splenocytes of individual transgenic mice that were positive at 10 µg/ml of peptide concentration. Number (10, 1 or 0.1) in parenthesis represents the lowest concentration of peptide (µg/ml) giving positive ELISpot response in peptide titration.
-represents no positive IFN-γ ELISpot response.
