    Dna-pkcs Regulation of the Allogeneic Immune Response

    L. Burdine, M. Burdine, Z. Waldrip, D. Harrison

    University of Arkansas, Little Rock, AR

    *Purpose: Organ transplantation is life-saving and continued investigations into immunological mechanisms that drive organ rejection are needed to improve immunosuppression therapies and prevent graft failure.…

    Detection of SARS-CoV-2 Specific Functional T Cells Using a Seven Color Flow Cytometry Assay

    L. Flebbe-Rehwaldt, J. Hayden, K. Mickey, S. Manley, S. Kleiboeker

    Eurofins-Viracor, Lees Summit, MO

    *Purpose: The need to evaluate SARS-CoV-2 immune responses is an important clinical research focus. Detecting neutralizing antibodies is one measure of immune response, but the…

    T-Cell Exhaustion in EBV DNAemic Solid Organ Transplant Recipients

    S. Kothari, T. Ku, D. Kumar, A. Humar, V. H. Ferreira

    Multi-Organ Transplant Program, University Health Network, Toronto, ON, Canada

    *Purpose: In transplant recipients, disease severity after infection with Epstein-Barr virus (EBV) may range from asymptomatic DNAemia to PTLD. Host factors likely play a key…
  • 2021 American Transplant Congress

    Gm2a: A Novel Regulatory Pathway Controlling Alloimmunity

    K. M. Baecher1, P. S. Heeger2, P. Cravedi2, M. Fribourg2, M. L. Ford1

    1Department of Surgery, Emory University, Atlanta, GA, 2Mount Sinai School of Medicine, New York, NY

    *Purpose: In recently published studies we discovered that the inhibitory receptor FcγRIIB regulates CD8+ T cell alloimmunity in a cell-autonomous fashion, and that increased expression…

    Novel Mixed Lymphocyte Reaction Monitoring System That Predicts Chronic Antibody- Mediated Rejection in Kidney Transplant Recipients

    N. Iwahara1, K. Hotta1, T. Tanabe1, D. Iwami2, Y. Takada3, H. Higuchi1, H. Sasaki3, H. Harada3, N. Shinohara1

    1Hokkaido Univercity, Sapporo, Japan, 2Jichi Medical University, Shimotsuke, Japan, 3Sapporo City General Hospital, Sapporo, Japan

    *Purpose: Chronic active antibody-mediated rejection (CAAMR) induced by de novo donor-specific antibodies (DSA) is the main cause of graft loss in the long-term. Currently, there…
  • 2020 American Transplant Congress

    Can Cxcr3+Cd62l–Cd4+ T Cells Serve as Early Warning Sentinels for Subclinical Rejections after Vascularized Composite Allotransplantation (vca)?
