Location of HA amino acid changes in influenza A(H7N9) escape mutants. Antigenic structure of the A(H7N9) A/Shanghai/2/2013 HA trimer (PDB ID: 4LN6) and location of the escape mutations to mAbs 7B5 (green), 5A6 (blue), 1E9 (magenta), and 98 (red). A, Top view—the location of each escape mutation on one HA molecule of the trimer is indicated. B, Side view—the location of three escape mutations (5A6, 98, and 1E9) are shown on one HA monomer of the HA trimer; the location of the 7B5 mutation on the other two HA monomers is shown by dotted lines
