Antibody Recognition of a Highly Conserved Influenza Virus Epitope
Open accessAbstract
Influenza virus presents an important and persistent threat to public health worldwide, and current vaccines provide immunity to viral isolates similar to the vaccine strain. High-affinity antibodies against a conserved epitope could provide immunity to the diverse influenza subtypes and protection against future pandemic viruses. Cocrystal structures were determined at 2.2 and 2.7 angstrom resolutions for broadly neutralizing human antibody CR6261 Fab in complexes with the major surface antigen (hemagglutinin, HA) from viruses responsible for the 1918 H1N1 influenza pandemic and a recent lethal case of H5N1 avian influenza. In contrast to other structurally characterized influenza antibodies, CR6261 recognizes a highly conserved helical region in the membrane-proximal stem of HA1 and HA2. The antibody neutralizes the virus by blocking conformational rearrangements associated with membrane fusion. The CR6261 epitope identified here should accelerate the design and implementation of improved vaccines that can elicit CR6261-like antibodies, as well as antibody-based therapies for the treatment of influenza.

In the citing paper
“The HA stem region is an attractive therapeutic epitope as it is highly conserved across all influenza A subtypes, and targeting this region can block the low-pH-induced conformational rearrangements associated with membrane fusion, which is essential for virus infection32,33.”

- Description of the analyzed sequence data set: A total of 5261 clones comprising all full-length nonredundant influenza A HA protein sequences were analyzed. Only lab strains were excluded from the analysis to avoid the effects of any mutations involved in adaption to culture in vitro. The data set included 854 H1 125 H2 1582 H3 144 H4 1384 H5 261 H6 359 H7 17 H8 334 H9 59 H10 71 H11 25 H12 26 H13 2 H14 5 H15 and 13 H16 sequences.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
