OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
2D analysis of TCR-pMHC interaction reveals differential cell fate governed by tissue compartmentalization
We discovered that during the early immune contraction phase of an acute infection with lymphocytic choriomeningitis virus, 2D TCR–pMHC affinity of TCR transgenic P14 T cells increased more for cells from the splenic red pulp (RP) than the white pulp (WP). This difference was governed by regulatory T cells and TGF-β. The increased 2D affinity of RP cells correlated with their increased ability to kill target cells and to recognize a CTL escape epitope. Memory precursors from WP preferentially developed into long-term memory cells as compared to cells from RP, despite expression of the same memory markers.
