Figure 1From: Cross-reactive human B cell and T cell epitopes between influenza A and B virusesComparison of the HA protein amino acid sequences among influenza A and B viruses. Multiple alignment was performed by CLUSTALW (available at http://www.genome.jp/tools/clustalw/). Protein accession numbers are shown in brackets next to influenza virus strain names. The fusion peptide is underlined [28]. B cell and CD4+ T cell epitopes are also shown.Back to article page
