End-Stage Renal Disease Does Not Impair the Large-Scale Generation of Potent Alloantigen-Specific Regulatory T Cells for Immunotherapy.
Background Alloantigen-specific natural occurring regulatory T cells (nTregs) have the potential to offer a more targeted approach of immunosuppression and are the cell type of…2016 American Transplant Congress
In Vitro Reactivity of CD4+ T Cells Subsets from Hosts with Antigen Specific Transplant Tolerance Mediated by CD4+CD25+T Cells.
Immune Tolerance Laboratory, UNSW Australia, Sydney, NSW, Australia.
In animals with transplant tolerance without lympho-hemopoietic chimerism peripheral T cells reactive to donor are not deleted, but their capacity to effect rejection is inhibited…2016 American Transplant Congress
The UK ONE Study: Safety and Feasibility of Regulatory T Cell Therapy in Renal Transplantation.
Introduction: The UK ONE Study trial investigates the safety and feasibility of regulatory T (Treg) cell therapy in renal transplantation.Materials and Methods: Eleven (9m;2f) living…2016 American Transplant Congress
Cytometric Deep Profiling of the CD8+ T-Cell Compartment in Transplant Patients with CMV Viremia.
Background: Cytomegalovirus (CMV) infection is a common opportunistic viral infection in transplant patients. Patterns of viremia and relapse are influenced by the host immune response,…2016 American Transplant Congress
Microarray Analysis of Transbronchial and Mucosal Biopsies in Lung Transplant Recipients Detects Molecular Changes of T-Cell Mediated Inflammation.
Purpose: The main diagnostic platform for rejection in lung transplant recipients is histology of transbronchial biopsies (TBB), a test with a poor performance and safety…2016 American Transplant Congress
Characterization of T Regulatory Type 1 (Tr1) Cells in Naïve and Transplanted Non-Human Primates.
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA.
BackgroundT regulatory Type 1 (Tr1) cells are peripheral CD4+FoxP3- regulatory T cells expressing CD49b and LAG-3 in mice and humans. Mouse Tr1 cells inhibit antigen-presenting…2016 American Transplant Congress
Function of Sertoli Cells in Regulating Allogeneic T Cell Differentiation into Treg and Th17 In Vitro.
The testis as an immune-privileged site allows long-term survival of allogeneic and xenogeneic transplants. Testicular Sertoli cells (SCs) can confer local immunoprotection for cotransplanted cells…2016 American Transplant Congress
A P2X7R Mutation with Hypermetabolic T Cells, Th1/Th17 Skewing and Reduced Cardiac Allograft Survival.
Background. The purinergic receptor-7 (P2X7R), primarily expressed on lymphocytes, senses ATP released extracellularly during cell damage and regulates T cell activation.Methods. In 640 heart transplant…2016 American Transplant Congress
Assessing Return of CMV Specific Cellular Immunity Using the T-SPOT.CMV Soon After Kidney Transplant with Thymoglobulin.
Infectious Disease, Massachusetts General Hospital, Boston, MA.
Background: We do not currently have sufficient predictive tools to determine risk of CMV infection after organ transplantation. Recent data suggest that assays of the…2016 American Transplant Congress
Toll-Like Receptor (TLR) 9-Induced Resistance to Murine Cardiac Allograft Tolerance Is Dependent Upon C3a and C5a Receptor (C3aR/C5aR) Signaling.
TLR stimulation has been shown by others to prevent costimulatory blockade-induced allograft tolerance. Immune cell derived complement activation products C3a and C5a amplify inflammation, enhance…
