Structure of intact IgE and the mechanism of ligelizumab revealed by electron microscopy

Background IgE is the central antibody isotype in TH2‐biased immunity and allergic diseases. The structure of intact IgE and the impact of IgE‐targeting molecules on IgE however remain elusive. In order to obtain insights into IgE biology and the clinical impact, we aimed for structure determination of IgE and the complex of IgE with the anti‐IgE antibody ligelizumab. Methods Structures of two distinct intact IgE with specificity for...
