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
T cell-dependent immunity commences with T-cell antigen receptor (TCR-CD3) signalling. TCR-CD3 features unique ligand recognition, signalling modalities and convoluted quaternary structure, diverging considerably from “classic”, evolutionary ancient membrane receptors of simpler molecular design and univocal relationship to ligands. TCR-CD3 recognises with exceptional sensorial and discriminatory ability antigens of varying structure, quantity and detection context. Given such a complexity, it is perhaps unsurprising that controversy exists on how TCR-CD3 works. I will report new data suggesting an allosteric mechanism by which TCR-CD3 transmits signals across the plasma membrane that should improve our understanding of how T cell activation begins.
