Paragraph: Highlights d Structure of bnAb S9-3-37 bound to influenza hemagglutinin stem was determined d D3-9-encoded region of S9-3-37 contributes majority of the interaction surface with HA d D3-9 gene segment of S9-3-37 can engage the HA stem in two different reading frames d D3-9 gene segment represents a recurring mechanism for antibody targeting of HA stem SUMMARY Discovery and characterization of broadly neutralizing antibodies (bnAbs) to the influenza hemagglutinin (HA) stem have provided insights for the development of a universal flu vaccine. Identification of signature features common to bnAbs from different individuals will be key to guiding immunogen design. S9-3-37 is a bnAb isolated from a healthy H5N1 vaccinee. Here, structural characterization reveals that the D3-9 gene segment of S9-3-37 contributes most of the interaction surface with the highly conserved stem epitope on HA. Comparison with other influenza bnAb crystal structures indicates that the D3-9 segment provides a general mechanism for targeting HA stem. Interestingly, such bnAbs can approach the HA stem with vastly different angles and orientations. Moreover, D3-9 can be translated in different reading frames in different bnAbs yet still target the same HA stem pocket. Thus, the D3-9 gene segment in the human immune repertoire can provide a robust defense against influenza virus.
