Non-Human Primate Auto-Immune Responses to Col V, Kα-1Tubulin and Vimentin Are P2X7R Dependent.
1Surgery, University of Wisconsin, Madison, WI; 2Medicine, University of Wisconsin, Madison, WI
Background: Auto-immune responses to Collagen type V (ColV) have been associated with coronary artery disease and lung or heart transplant rejection in humans and murine…2017 American Transplant Congress
Blood Tfh Cells Exhibit Impaired B Cell Help in Operationally Tolerant Patients.
Introduction: Operationally tolerant (TOL) patients display a defect of B cell differentiation, with a deficiency in circulating plasma cells secreting antibodies, which could partly contribute…2017 American Transplant Congress
Loss of Bat3 Could Promote Transplant Tolerance by Regulating CD4 + T Cells Function.
Objective: To explore the effect of Bat3 on T cells and its function in transplant tolerance inductionMethodsWe generated Bat3flox/flox CD4-Cre + mice, sorted WT and…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…2016 American Transplant Congress
IL-17-Producing CCR6+CD4+ Th17 Cells Drive Intestinal Allograft Rejection in Humans.
MedStar Georgetown Transplant Institute, Washington DC.
A. Allograft rejection remains a significant source of mortality and morbidity in intestinal transplant (ITx) recipients. However, the underlying mechanisms remain unclear. The purpose of…2016 American Transplant Congress
CTLA4 Negatively Regulates Donor-Reactive CXCR5+PD1+ T Follicular Helper Cell Responses Following Transplantation.
1Emory Transplant Center, Atlanta; 2Bristol-Myers Squibb, Princeton.
Costimulation blockade of the CD28 pathway in the form of CTLA4Ig is known to attenuate T cell dependent antibody responses. T follicular helper (Tfh) cells…2016 American Transplant Congress
Single Cell Profiling of Th9 Cells Allows Identification of Functionally Different Subsets.
Institute of Medical Immunology, Charite University Medicine, Berlin, Germany.
T helper type 9 (Th9) cells represent a distinct subset of CD4+ effector T cells that is characterized by high secretion of interleukin (IL)-9. Protective…2016 American Transplant Congress
The Property of Modulatory T Cells Generated by Mixed Lymphocyte Culture with CD154 Blockade.
Center for Transplantation Science, Massachusetts General Hospital, Boston, MA.
Background:Regulatory T cell (Treg) immunotherapy has been applied to minimize the immunosuppressive drugs in clinical transplantation. To avoid contamination of CD4+CD25- T cells, only highly…2016 American Transplant Congress
Indirect Allo-Antigen Stimulation Identifies the Presence of Either Regulatory IL-10 or of Effector Cytokines IFN-g, IL-21, IL-17a Production by Human Blood Allo-Reactive Memory TFH and TCONV CD4+ T Cells.
Surgery, Thomas E. Starzl Transplantation Institute, Pittsburgh, PA.
Background: It is well accepted that human CD4+ T cell allo-immunity plays pivotal roles during cellular and humoral allograft rejection. While our previous analysis showed…2016 American Transplant Congress
Th17 Development Is Critical for Airway Epithelial Injury After Transplantation.
Department of Immunology, Capital Medical University, Beijing, China.
Background: Development of obliterative bronchiolitis (OB) is the biggest obstacle that limits long-term allograft survival and clinical application of lung transplantation, and the precise mechanisms…
