Role of APC Subsets in Rejection and Graft-Versus-Host-Disease in Intestinal Transplantation
Transplant Institute, MedStar Georgetown University, Washington, DC
*Purpose: Intestinal transplantation (ITx) is arguably the most immunogenic and complex organ transplantation, often accompanied with high rates of allograft rejection (AR) and graft-versus-host disease…2020 American Transplant Congress
Influence of Microbial Communities on Transplantation
*Purpose: A diverse microbiome is important in the generation, maintenance, and function of the immune system. Specific bacterial communities may have a relationship with organ…2020 American Transplant Congress
Suppressing Laminin Alpha5 Creates Tolerogenic Niches for Allograft Survival
1UMB, Baltimore, MD, 2Harvard University, Boston, MA
*Purpose: Laminin α5 (Lama5) regulates CD4 T cell migration and function. We hypothesized that stromal Lama5 regulates the structure of the lymph node (LN) microenvironment…2020 American Transplant Congress
Evaluating Preformed Donor HLA Reactive T Cells Using PIRCHE-II Algorithm
*Purpose: De novo donor-specific HLA antibodies (dnDSA) production involves the indirect allorecognition pathway in which recipient CD4+T cells recognize donor-HLA-derived peptide and recipient HLA class…2020 American Transplant Congress
Accelerated Bronchiolitis Obliterans after Lung Transplant Promoted by the ATG16L1 rs2241880 Mutation is Coupled to Mitochondrial Damage and Metabolic Alterations in Monocyte-Derived Alveolar Macrophages
*Purpose: Bronchiolitis obliterans (BOS) remains a major cause of death for lung transplant recipients, and the mechanisms that drive BOS remain poorly understood and require…2020 American Transplant Congress
Strong Engagement of CD137 Suppresses Graft-Versus-Host Disease Through Dendritic Cells
*Purpose: We previously demonstrated that anti-CD137 agonist prevent acute graft-versus-host disease (GVHD) and chronic GVHD in the parent-into-unirradiated F1 acute or chronic GVHD model. Although…2020 American Transplant Congress
Tertiary Lymphoid Organs in Renal Chronic Allograft Rejection
Starzl Transplantation Institute, Pittsburgh, PA
*Purpose: Chronic allograft rejection remains a major obstacle to long-term allograft survival. Tertiary lymphoid organs (TLOs) are ectopic lymphoid structures that arise in non-lymphoid tissues…2020 American Transplant Congress
Lymph Node Stromal Laminin Alpha5 Regulates Antigen Specific T Cell Adaptive Immunity
1UMB, Baltimore, MD, 2Harvard University, Boston, MA
*Purpose: Laminin α5 (Lama5) is associated with immunity and regulates T cell entry and responses within the lymph node (LN). We hypothesized that stromal Lama5…2020 American Transplant Congress
Role of Cross-Dressing in Kidney Transplantation
Thomas E. Starzl Transplantation Institute, Pittsburgh, PA
*Purpose: Activation of host T cells that mediate allograft rejection is relied on dendritic cells (DCs) presenting alloantigens to T cells. Our recent study revealed…2020 American Transplant Congress
Migration of Passenger Leukocytes During Ex Vivo Warm Perfusion
*Purpose: Organ transplantation is a unique immunologic situation in which donor and recipient antigen presenting cells (APCs) are present upon reperfusion. Passenger leukocytes (PL) are…
