On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Cytotoxic T lymphocytes (CTLs) are critical for defense against intracellular pathogens and cancer. CTL differentiation begins when a naïve CD8+ T cell recognizes a peptide-MHC ligand complex through its T cell receptor (TCR), triggering a cascade of activation events. The interaction of the TCR with a particular peptide-MHC complex is exquisitely sensitive, such that single amino acid changes in the presented peptide can dramatically alter the activation of responding T cells. Multiple mechanisms have been proposed to underlie this phenomenon, but these cannot be distinguished through snapshot measurements in bulk cellular populations. In this talk, I will describe how we address this using multidimensional measurements (single-cell RNAseq and mass cytometry) of molecular activation events in individual cells over time.
