IL-33 Enhances the Ability of Dendritic Cells to Expand Human Regulatory T Cells.
Introduction:The importance of increasing the number of regulatory T cells (Treg) relative to T effectors for the promotion of long-term experimental allograft survival/tolerance is well-established.…2017 American Transplant Congress
Heat Shock Protein 90 Inhibitor, 17DMAG Suppresses Acute Allograft Rejection and Prolongs Allograft Survival in Solid Organ Transplantation.
Urology, Sapporo Medical University School of Medicine, Sapporo, Japan
Purpose: Heat shock protein 90 (HSP90) is a ubiquitously expressed molecular chaperone that is associated with the correct activation of client proteins. Important roles of…2017 American Transplant Congress
CD8+ TAb-supp Cells Are Key Inhibitors of Humoral Alloimmunity by Inhibiting CD4+TFH Cells and Killing Germinal Center B Cells.
Surgery, The Ohio State University Wexner Medical Center, Columbus, OH
Alloantibodies (alloAb) play a critical role in acute and chronic rejection after transplantation (Tx). It is well known that CD4+ T cells and B cells…2017 American Transplant Congress
High Eomesodermin Expression Correlates with Potent Human Allo-Reactive CD8+ Effector T Cells.
Surgery, University of Pittsburgh, Pittsburgh, PA
BackgroundThe transcription factors Eomesodermin (Eomes) and T-bet are thought to play critical roles in CD8+ effector memory T cell development. However, the role of Eomes…2017 American Transplant Congress
Assessment of C4d Positive Biopsies with No Histological Evidence of Inflammation Using Nanostring nCounter Technology.
Deposition of C4d has been an established part of the Banff classification scheme for antibody mediated rejection (AbMR) since 2001. More recently, C4d negative AbMR…2016 American Transplant Congress
Polyfunctionality of CD8 T Cell Responses to Cytomegalovirus in Transplant Patients.
Background: Cytomegalovirus (CMV) infection causes significant morbidity including allograft damage in transplant patients. Primary infection with CMV is rapidly resolved in healthy individuals; memory T…2016 American Transplant Congress
IFN-γ and Contact-Dependent Cytotoxicity Are Rate-Limiting for NK Cells in a Model of Antibody-Mediated Chronic Rejection.
BACKGROUND. Natural killer (NK) cells are key components of the innate immune that contribute to acute and chronic graft rejection. After engagement with antibody, NK…2016 American Transplant Congress
Type-I Interferon Induced Cross-Competition of IL-10 Signaling and Its Role in the Abrogation of Transplant Tolerance.
Plastic Surgery, Johns Hopkins University, School of Medicine, Baltimore, MD.
PurposeA growing body of evidence shows that induction of long term transplant survival by “costimulation blockade” (CoB) regimens is impaired by inflammatory responses. In particular,…2016 American Transplant Congress
An Interventional Study Evaluating Cell Mediated Immunity to Guide Therapy for CMV Viremia.
Multi-Organ Transplant, University Health Network, Toronto, ON, Canada.
BackgroundPatients treated for CMV viremia commonly relapse after discontinuation of therapy. CMV-specific CD8+ T-cell mediated immunity (CMI) is useful to predict the risk of CMV…2016 American Transplant Congress
Evaluation of a Novel Global Immunity Assay to Predict Infections in Organ Transplant Recipients.
Multi-Organ Transplant, University Health Network, Toronto, Canada.
BackgroundSimple standardized measures of global immunity may help predict the risk of infections post-transplant. The Quantiferon-Monitor (QFM) test is a novel interferon-γ (IFN-γ) release assay…
