Abstract[English]
Stabilised Herpesvirus antigens The invention relates to stabilised Herpesvirus antigens, including Herpesvirus glycoprotein B (gB) antigens comprising a non-native Membrane Proximal Region (MPR), use of non-native MPR structures to stabilise the Herpesvirus gB in its pre-fusion form, and methods for designing non-native MPR structures. The invention further relates to a stabilised Herpesvirus gB for use as an immunogen, immune reagent or a vaccine.[French]
