Lymphotoxin Controls Treg Interactions With Lymphatic Endothelial Cells and Interstitial Migration In Vivo
University of Maryland, Baltimore, MD.
Introduction: Lymphotoxin (LT) coordinates the development, organization and structure of lymphoid organs, and LTβreceptor (LTβR) is involved in thymocyte migration. However, LT has no described…2015 American Transplant Congress
T Cell Transfer With iNKT Cell Activation Facilitate Engraftment of Bone Marrow Cells Without GvHD
Contamination of allogenic T cells is considered to be a risk factor of graft versus host disease (GvHD) in bone marrow transplantation (BMT), whereas it…2015 American Transplant Congress
IFNγ Is Required for nTreg Afferent Lymphatic Migration
Surgery, University of Maryland, Baltimore, MD.
Background: Natural Treg (nTreg) must migrate from graft to draining lymph node (LN) to prolong islet allograft survival, and we previously showed that the transcription…2015 American Transplant Congress
Structure/Function Insights Into Treg Biology: Hdac11 Is a Foxp3 Deacetylase Whose Targeting Promotes and Stabilizes Foxp3 Expression and Leads to Long-Term Allograft Survival
1CHOP & UPenn, Philadelphia; 2Uni of Illinois at Chicago, Chicago.
Aim: There are huge scientific, economic and practical advantages in developing pharmacologic approaches to enhance Foxp3+ Treg function in allograft recipients versus simply injecting enormous…2015 American Transplant Congress
Conversion to Belatacept After Kidney Transplantation Does Not Alter Immunophenotype
1University Medicine Charité, Berlin, Germany; 2Labor Berlin GmbH, Berlin, Germany.
Belatacept offers a new option for renal allograft recipients who are suffering from side effects of calcineurin inhibitor or mTOR. Such a conversion may result…2015 American Transplant Congress
Inhibition of T Cell Metabolism Reveals a New Approach to Preventing Graft Rejection
Upon antigen recognition and co-stimulation, T cells up-regulate the metabolic machinery necessary to proliferate and sustain effector function. Hallmarks of this response include a switch…2015 American Transplant Congress
Eomes-Expressing CD8+ T Cells and Th17 Cells Mediate Costimulatory Blockade-Resistant Allograft Rejection in Mice
The etiology of costimulatory blockade-resistant allograft rejection remains unclear. Therefore, the purpose of this study was to evaluate the responsiveness of distinct CD4+ and CD8+…2015 American Transplant Congress
The Preservation Technique Modulates the Immunological Milieu in Lung Transplantation and Affects the Pro-/ Anti-Inflammatory Balance
Little is known regarding the influence of different preservation techniques (i.e. cold static storage with Perfadex® or Celsior® solution) on the immunological milieu, especially lung-resident…2015 American Transplant Congress
Liver-Specific Transcription Factor ATF5 Participates in Regulation of IFN-γ/B7-H1 Signaling Pathway in Liver Mesenchymal Cells
Liver transplant tolerance was initially discovered in pigs, rats and mice. A recent paper reviewed ∼400 liver transplant patients worldwide who had undergone weaning of…2015 American Transplant Congress
CN Inhibition (But Not mTOR Inhibition) of a Novel CD8+ T Cell Regulatory Mechanism Results in Higher Alloantibody Posttransplant
Department of Surgery, CTC, The Ohio State University Wexner Medical Center, Columbus, OH.
MTOR inhibitors [mTORi; Rapamycin, (Rapa)] and calcineurin inhibitors [CNi; Tacrolimus (Tac)] are immunosuppressive drugs commonly used to suppress the rejection of transplanted organs and tissues.…
