[h=1]Design and Structure of an Engineered Disulfide-Stabilized Influenza Hemagglutinin Trimer.[/h] Lee PS[SUP]1[/SUP], Zhu X[SUP]2[/SUP], Yu W[SUP]2[/SUP], Wilson IA[SUP]3[/SUP].

[h=3]Abstract[/h] We engineered a disulfide-stabilized influenza hemagglutinin (HA) trimer, termed HA[SUB]3[/SUB]-SS, by introducing cysteine residues in the HA stem to covalently bridge the three protomers. HA[SUB]3[/SUB]-SS has increased thermostability compared to wild-type HA and binding of head- and stem-targeted antibodies is preserved; only minor structural changes are found in the vicinity of the additional disulfide. This platform has been applied to H1 and H3 HAs and provides prospects for design of intact, stabilized influenza HA immunogens.
