Correlation of Crossmatch Predictions with Actual Results and Clinical Outcomes
1Vanderbilt University Medical Center, Nashville, TN, 2Dialysis Clinic, Inc, Nashville, TN
*Purpose: Flow cytometry crossmatching (FXM) is recognized as a valuable tool to assess immunological risk prior to renal transplantation. The increased resolution in HLA typing…2019 American Transplant Congress
Epitope-Based Matching in Pediatric Kidney Transplantation
*Purpose: Following the allocation of a transplant by the allocation system, each pediatric transplant team reviews the proposal and decides based on various criteria whether…2019 American Transplant Congress
Synergistic Effect of HLA Eplet Mismatch Load and CMV Viremia on Clinical Antibody-Mediated Rejection in Lung Transplantation
*Purpose: De novo donor specific antibodies (dnDSA) occur in up to 50% of lung transplant (LUTX) recipients within one year and are associated with increased…2019 American Transplant Congress
Novel Role of Qa-1-Restricted Immunoregulation in Murine Cardiac Transplantation
1Medicine, Brigham and Women's Hospital, Boston, MA, 2Dana-Farbar Caner Institute, Boston, MA
*Purpose: HLA-E is an MHC class-1b molecule that is under-studied in the transplant setting. Recent clinical studies have revealed a robust association between allograft outcome…2019 American Transplant Congress
MHC Cross-Dressing in Mixed Hematopoietic Chimerism
*Purpose: Achieving specific long-term allograft survival without ongoing immunosuppression is one of the main objectives in transplantation. Mixed hematopoietic chimerism is a strategy that has…2019 American Transplant Congress
Dendritic Cells Transduced with Autoimmune Regulator Exhibit Immature Properties and Prolong Heart Allograft Survival
Organ Transplant Center, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China
*Purpose: The expression of the Aire (Autoimmune regulator) gene was observed to inhibit the maturation and activation of dendritic cells (DCs) and induce transplantation tolerance.*Methods:…2019 American Transplant Congress
Prolongation of Allograft Survival via Donor MHC Chimerism Induced by Exosomes
*Purpose: Achieving robust and durable host immune tolerance of allogeneic transplants is the ultimate goal in clinical transplantation. Mixed chimerism induced via donor bone marrow…2018 American Transplant Congress
Specific Monocyte Memory to Allogeneic MHC Mediated by Paired Immunoglobulin Receptors (PIR)
Monocytes distinguish between self and allogeneic non-self and contribute to allograft rejection by generating mature, IL-12+, DCs. The initial trigger of monocyte differentiation to DCs…2018 American Transplant Congress
The Role of pDCs in Formation of Treg-Rich Organized Lymphoid Structures in Spontaneously Accepted Murine Kidney Allografts is Dependent on Mismatching of MHC Class II Molecules at the H2-I-Ab Locus
Introduction: Our lab has demonstrated that murine kidney allografts are spontaneously accepted in specific donor-recipient strain combinations. Histologic examination of spontaneously accepted DBA/2J (DBA) kidneys…2018 American Transplant Congress
Informatics Tools for Mapping Molecular HLA Typing Data to UNOS Antigen Equivalencies
Introduction:Molecular HLA typing must be converted to antigen equivalencies for entry into the UNOS database, UNet. Maintaining an up-to-date mapping table for this purpose has…
