OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Influenza hemagglutinin (HA) is the canonical type-I viral envelope glycoprotein, and provides a template for the membrane fusion mechanisms of numerous viruses. Here, using single-molecule Förster resonance energy transfer (smFRET) imaging we directly visualized conformational changes of HA trimers on the viral surface. These findings reveal the coordination between receptor binding and HA conformational dynamics, which facilitates efficient fusion.
