During Michaelmas Term, OxTalks will be moving to a new platform (full details are available on the Staff Gateway).
For now, continue using the current page and event submission process (freeze period dates to be advised).
If you have any questions, please contact halo@digital.ox.ac.uk
Major Histocompatibility Complex (MHC molecules) are a cornerstone of the adaptive immune system. They present antigens to T-cells for surveillance.
While we have a reasonably large number of experimentally determined three-dimensional structures of MHC molecules, there is low diversity in the dataset and it represents a very small fraction of the universe of potential complexes.
Despite this caveat, we can discern patterns within antigen presentation/recognition in the bulk data. If we benchmark these methods robustly, we can potentially extend using synthetic data from machine learning prediction methods such as AlphaFold.
