Single Cell Analysis Reveals Endothelial Activation of Interleukin-6 Mediated Signaling Pathway in Microvascular Inflammation with and without c4d
1University of Michigan, Ann Arbor, MI, 2Henry Ford Hospital, Detroit, MI
*Purpose: Microvascular inflammation (MVI) is a feature of antibody mediated rejection. MVI can be seen with or without activation of other effectors of antibody injury…2020 American Transplant Congress
Validation of Prognostic Index for Allograft Outcome in Kidney Transplant Recipients with Transplant Glomerulopathy
*Purpose: Kidney transplant recipients with Transplant Glomerulopathy (TG) have very poor allograft survival compared to those without TG. The objective of this research was to…2020 American Transplant Congress
Alterations in Left Ventricular Wall Thickness after Cardiac Transplantation
*Purpose: We investigated changes in cardiac wall thickness of donor hearts over time, including the peri-operative OHT period (within 4 days after transplantation) and up…2020 American Transplant Congress
TGF-b Induced Myeloid-Derived Suppressor Cells Prevent Transplatation Rejection by Promoting Immune Tolerance
Department of Urology, Beijing Chaoyang Hospital, Capital Medical University, Beijing, China
*Purpose: Myeloid-derived suppressor cells (MDSCs) are a class of heterogeneous myeloid cells with immunosuppressive function. An effective method to produce MDSCs with better capacity and…2020 American Transplant Congress
Is Ischemia Reperfusion Injury Immediately after Heart Transplantation Correlated to Increased Intimal Thickening in the First Year?
Cedars-Sinai Smidt Heart Institute, Los Angeles, CA
*Purpose: Ischemia reperfusion injury (IRI) is not uncommon in heart transplant patients due to high dose inotropes, ischemic time, and technical surgical reasons. Ischemia in…2020 American Transplant Congress
Graft Perfusion with an Hsp90 Inhibitor Prolongs Graft Survival in Murine Heart Transplantation by Modulating Expression of Cyclin-Dependent Kinases and the Senolytic Effect
Department of Urology, Sapporo Medical University, Sapporo, Japan
*Purpose: We have previously demonstrated that administration of alvespimycin, a heat shock protein 90 (HSP90) inhibitor, prolongs the allograft survival in murine skin and heart…2020 American Transplant Congress
Pre- And Post-Transplant (Tx) Clazakizumab (CLZ, Humanized Anti-IL-6 Monoclonal Antibody) Treatment Increased Regulatory T Cell (Treg) Percentage in CD4+ T Cells in HLA-Sensitized Kidney Transplant Patients (HS KTx Pts)
*Purpose: IL-6 is a B cell growth factor and pro-inflammatory cytokine. Inhibition of IL-6 signaling modulates B cell activation and inflammatory process possibly through Treg…2020 American Transplant Congress
Recipient Myeloid Cell Myeloperoxidase is Required for Nk Cell Activation During Antibody-Mediated Allograft Rejection
Immunology, Cleveland Clinic Lerner Research Institute, Cleveland, OH
*Purpose: Dysregulated donor-specific antibody (DSA) responses are induced in B6.CCR5-/- mice transplanted with complete MHC mismatched A/J kidney allografts and are required for rejection of…2020 American Transplant Congress
Missing Self Increases the Incidence of Microvascular Inflammation after Kidney Transplantation
*Purpose: Anti-HLA donor-specific antibodies (HLA-DSA) are often absent in serum of kidney allograft recipients with biopsies demonstrating microvascular inflammation (MVI), the histological hallmark of antibody-mediated…2020 American Transplant Congress
HLA-DR/DQ Molecular Mismatch Dictates Early Risk of De Novo Donor-Specific Antibody Development and Offers a Personalized Approach to Immunosuppression Management in Kidney Transplantation
*Purpose: Clinicians have few tools to predict the risk of alloimmune injury in a patient undergoing renal transplantation, as traditional demographic or clinical variables lack…
