Amino acid changes in CD4+ and CD8+ specific T cell epitopes of HPV16 E6 and E7 proteins. Amino acid changes in at least one of the 51 HPV16 isolates at CD4+ and CD8+ specific T cell epitopes are marked with hollow and solid arrows, respectively. Stacking arrows indicate that the amino acid change is in a peptide which serves as both CD4+ and CD8+ epitopes.
