IL-10 Signaling in T Cells Modulates Costimulation-independent Activation and is Essential for Transplant Tolerance Induction
*Purpose: Costimulation blockade (CoB)-based immunotherapy remains a very promising approach for better management of transplant recipients. Understanding the mechanisms that impact the efficacy of CoB…2021 American Transplant Congress
Role of Baseline PD-1 Checkpoint Inhibitor Pathway Expression in Bridge to Liver Transplant Hepatocellular Carcinoma
Ochsner Health, New Orleans, LA
*Purpose: Response to first line liver-directed therapy (LDT) in hepatocellular carcinoma (HCC) has important implications in both bridge to transplant (BTT) success as well as…2021 American Transplant Congress
Evaluation of the Differentiation Program of Endogenous Antigen-specific CD8+T Cells Following Transplantation
1Pathology, Johns Hopkins University, Baltimore, MD, 2Surgery, Emory Transplant Center, Atlanta, GA
*Purpose: Despite advances in the survival of transplanted organs, acute T cell mediated rejection remains a significant clinical problem with few effective or targeted treatments.…2021 American Transplant Congress
T-Cell Responses in Solid Organ Transplant Recipients with SARS-CoV-2 Infection
University Health Network, Toronto, ON, Canada
*Purpose: Preliminary data suggest solid organ transplant (SOT) recipients may be at high-risk for developing severe COVID-19. This may be due in part to alterations…2021 American Transplant Congress
P2X7 Receptor Activity Mediates Th17-Specific Self- and Alloreactivity in Non-Human Primates
Department of Surgery, University of Wisconsin, Madison, WI
*Purpose: The broadly expressed ATP-binding purinergic receptor, P2X7 (P2X7R) is involved in the Th17 mediated cellular immune response to allo- and select self-antigens (Collagen type…2021 American Transplant Congress
Reassessing TCMR in Kidney Transplant Indication Biopsies: Emerging Evidence for Partial Exhaustion in Late TCMR
1Alberta Transplant Applied Genomics Centre, Edmonton, AB, Canada, 2., ., AB, Canada
*Purpose: We rederived the MMDx rejection archetypes in an expanded set of 1679 kidney transplant biopsies to add power and potentially define heterogeneity in TCMR.…2021 American Transplant Congress
Establishing a Linear Program for the Development of Costimulation Resistant T-Cells
*Purpose: CD4+CD57+PD1-T-cells are primed effectors capable of mediating belatacept-resistant rejection, however, the developmental program giving rise to these cells has not been elucidated in detail.…2020 American Transplant Congress
Lateral Flow Assay to Detect Soluble CD25 after Kidney Transplantation
Faculty of Natural Sciences, Institute of Technical Chemistry, Hannover, Germany
*Purpose: Kidney transplantations are one of the most common transplantations in the world; 80.696 kidneys were transplanted in 2017. Despite tremendous improvements in quality and…2020 American Transplant Congress
Peripheral Blood RNA Sequencing Unravels a Differential Role of Coding and Non-Coding Genes by Types of Kidney Allograft Rejection
*Purpose: Peripheral blood molecular patterns characterizing the different effector immune pathways driving kidney allograft rejection remain to be fully completely elucidated, to more fully type…2020 American Transplant Congress
Withaferin A Prolongs Islet Allograft Survival in a Mouse Transplant Model by Preventing T Lymphocyte Proliferation and Dendritic Cell Maturation
*Purpose: Chronic decline in islet graft function and toxicities imposed by immunosuppressant drugs remain as challenges to the widespread use of islet transplantation for type…
