    A Novel Computational HLA Matching Algorithm for Improving Donor-Recipient Histocompatibility and Graft Outcomes After Kidney Transplantation.

    V. Kosmoliaptsis,1 D. Mallon,1 S. Fuggle,2 R. Johnson,2 C. Watson,1 J. Bradley,1 C. Taylor.1

    1Department of Surgery, University of Cambridge, Cambridge, United Kingdom; 2NHS Blood and Transplant, Bristol, United Kingdom

    Introduction: Human Leukocyte Antigen (HLA) matching is a central objective of kidney allocation policies, but current assessment of histocompatibility is inadequate. Building on our previous…
  • 2017 American Transplant Congress

    Validation of a Novel Computational Approach for Predicting HLA Immunogenicity Based on Quantification of Structural and Surface Electrostatic Potential Differences Between Donor and Recipient HLA.
