Antigen distortion allows influenza virus to escape neutralization.
D.Fleury, S.A.Wharton, J.J.Skehel, M.Knossow, T.Bizebard.
The structure of the hemagglutinin (HA) of a mutant influenza virus that escapes neutralization by a monoclonal antibody shows that the mutation causes changes in HA structure which avoid an energetically less favorable conformation. However, the structure of the mutant HA.Fab complex indicates that the antibody binds selectively to mutant HA in a wild type-like distorted conformation. The association of an antibody with a less favored HA conformation represents an alternative to previously described mechanisms of escape from neutralization by antibodies.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
