B2-Adrenergic Receptor Activation in Donor Cells Inhibits T Cell Trafficking in Vascularized Composite Tissue Allotransplants
*Purpose: Transplantation of faces, hands, and limbs using vascularized composite allotransplantation (VCA) has faced significant challenges hindering its routine implementation in the clinic. One critical…2020 American Transplant Congress
Single Cell RNA Sequencing of Normal Kidney Allograft Surveillance Biopsies Show Evidence of Dynamic Glomerular Endothelial Cell Activation
University of Michigan, Ann Arbor, MI
*Purpose: Indication and surveillance biopsy studies show a high prevalence of post kidney transplant (KT) glomerular disease (ElZoghby 2009,Stegall 2017) that cannot be explained by…2020 American Transplant Congress
Interferon-Beta Acts Directly on T Cells to Promote Foxp3 Acetylation in Regulatory T Cells
Medicine, Icahn School of Medicine at Mount Sinai, New York, NY
*Purpose: Interferon-β (IFNβ) is a type I interferon that binds to its receptor (IFNAR) expressed on immune cells. It has known antiviral and pro-inflammatory activity…2019 American Transplant Congress
A Potential Role for IgE-Mediated Immune Response in the Pathogenesis of Chronic Antibody-Mediated Rejection
*Purpose: Chronic antibody-mediated rejection (CAMR) is the main cause of graft loss and shares with systemic lupus erythematosus (SLE) the antibody-mediated kidney damage and the…2019 American Transplant Congress
Type-1 Interferons Impair the Key Immunoregulatory Activity of IL-10 in the Promotion of Transplant Tolerance
Plastic Surgery, Johns Hopkins University, Baltimore, MD
*Purpose: Induction of long term transplant survival by “costimulation blockade” (CoB) regimens is impaired by inflammatory responses. Despite the identification of type-1 interferons (TI-IFN) as…2019 American Transplant Congress
Human Adenovirus-Specific T Cell Response in Kidney Transplant Recipients Diagnosed with Adenovirus Infection
*Purpose: Cell-mediated immunity plays an important role in controlling human adenovirus (HAdV) infection after kidney transplantation (KT). We investigated T cell lymphocyte subsets and HAdV-specific…2019 American Transplant Congress
Murine Cytomegalovirus Infection Down-Regulates Receptor Tyrosine Kinase MerTK on Macrophages to Abrogate Allograft Tolerance
*Purpose: Cytomegalovirus (CMV) is one of the most common pathogens infecting solid organ transplant recipients. We recently showed that (1) CMV infection impairs the induction…2019 American Transplant Congress
Peripheral Blood Chemokine Levels in Kidney Allograft Rejection
University Hospitals Leuven, Leuven, Belgium
*Purpose: Cytokines and chemokines play a critical role in acute rejection after kidney transplantation and may be of importance in the quest for better diagnostic…2019 American Transplant Congress
Interferon Sensitivity Promotes Recovery from Acetaminophen Induced Liver Injury
Inflammation and Immunity, Cleveland Clinic Foundation, Cleveland, OH
*Purpose: The current study was undertaken to assess the role of inflammatory signaling during induction of and recovery from acetaminophen induced acute liver failure.*Methods: C57BL/6…2019 American Transplant Congress
IL-10+ Plasma Cells Are Not Required for Breg Activity and Are Counterbalanced by Novel Pro-Inflammatory Plasma Cells
University of Pittsburgh, Pittsburgh, PA
*Purpose: Classically, B cells differentiate into Ab-secreting plasma cells (PCs; B220lowCD138hiBlimp1+Ig+) providing humoral immunity. B cells can also inhibit or promote immune responses through the…
