    Use The Vascularized Sentinel Skin Flap For Prophylaxis Of Antibody-mediated Rejection After Kidney Transplantation In Highly Sensitized Patients

    A. Kalachyk, A. Nosik, D. Sadouski, H. Startsava

    Nephrology, RRT and Kidney Transplant Unit, Minsk scientific and practical center for surgery, transplantation and hematology, State institution, MInsk, Belarus

    *Purpose: Patients with high titer of preexisting donor specific anti-HLA antibodies (DSA) have very high risk of antibody mediated rejection development and followed by the…

    Role of Group 2 Innate Lymphoid Cells in Murine Heart Transplant

    J. Ge1, L. Ott1, A. Das1, J. Markmann2, A. Cuenca1

    1Department of Surgery, Boston Children's Hospital, Boston, MA, 2Division of Transplant Surgery, Department of Surgery, Massachusetts General Hospital, Boston, MA

    *Purpose: Group 2 innate lymphoid cells (ILC2s) have been shown to play key roles in manipulating adaptive immunity. They regulate CD4+ T cell biology not…

    Contributions of Allogenicity and Antigen Presentation to Regulatory B Cell Suppression

    K. Lee, F. Qiang, K. Deng, R. Matheson, J. Lei, C. LeGuern, J. Markmann

    Center for Transplantation Sciences, Boston, MA

    *Purpose: We previously generated in vitro Toll-like receptor (TLR)-activated B cells became regulatory B cells (Bregs) that suppress T cell proliferation and promote allograft tolerance.…
  • 2021 American Transplant Congress

    Combined Donor Derived Cell Free DNA (AlloSure) and Peripheral Immune Cell Gene Expression (AlloMap) Testing for the Diagnosis of Rejection in Kidney Transplant Recipients with De Novo Donor Specific Antibodies

    K. R. Degner, S. Parajuli, F. Aziz, N. Garg, D. Mandelbrot, M. Mohamed, K. Van Hyfte, S. R. Reese, N. A. Wilson, A. Djamali

    University of Wisconsin, Madison, WI

    *Purpose: Combined donor-derived cell-free DNA (dd-cfDNA, AlloSure) and peripheral immune cell gene expression (AlloMap) may increase the predictive value of de novo DSA (dnDSA) for…
  • 2021 American Transplant Congress

    Marginal Zone B Cells Support Donor-Specific Alloantibody Responses to Heart Allografts

    V. Gorbacheva, R. Fan, W. Baldwin, R. Fairchild, A. Valujskikh

    Inflammation and Immunity, Cleveland Clinic, Cleveland, OH

    *Purpose: Production of high affinity isotype-switched donor specific alloantibodies (DSA) after transplantation is associated with germinal center formation by follicular (FO) B cells whereas the…
  • 2021 American Transplant Congress

    Association Between HLA Class II and TLR4 Regulates HLA-II Stimulated P-selectin Expression and Monocyte Capture to Endothelial Cells

    Y. Jin, J. Nevarez-Mejia, E. F. Reed

    Pathology and Laboratory Medicine, University of California Los Angeles, Los Angeles, CA

    *Purpose: Antibody-mediated rejection (AMR) is a major obstacle for long-term allograft survival. Donor specific HLA antibodies (DSA) contribute to the process of AMR by binding…
  • 2021 American Transplant Congress

    Risk Stratification of Kidney Transplant Patients According to the Different Level of HLA-DQ Disparities

    A. Senev1, A. R. Tambur2, M. Naesens1

    1Microbiology, Immunology and Transplantation, KU Leuven, Leuven, Belgium, 2Northwestern University, Chicago, IL

    *Purpose: It is becoming clear that de novo donor-specific antibodies (dnDSA) against HLA-DQ are the most prevalent and the leading cause of chronic antibody-mediated rejection…
  • 2020 American Transplant Congress

    HLA Molecular Mismatch is an Independent Correlate of T-Cell Mediated Rejection and Potential Prognostic Biomarker in Renal Transplantation

    C. Wiebe1, D. Pochinco2, I. W. Gibson3, J. Ho1, P. Birk4, A. Goldberg4, M. Karpinski5, J. Shaw5, R. N. David5, P. W. Nickerson1

    Thymic B Cells: A Means to Control Regulatory Tolerance

    C. LeGuern1, S. Germana1, N. Feeney1, Z. Wang2, N. Tanimine1, C. Huang3, C. Rickert1, J. Markmann1

    1Surgery, Center for Transplantation Sciences, Massachusetts General Hospital, Charlestown, MA, 2University of Colorado Denver, Aurora, CO, 3Surgery, University of Colorado Denver, Aurora, CO

    *Purpose: Therapies involving CD4 regulatory T cells (Tregs) are promising approaches to mitigate graft rejection and autoimmunity. Understanding of the activation mechanisms that initiate Treg…
