Differential Role of PI3K Subunits Gamma and Delta in Regulatory T Cells Homeostasis in Allotransplantation
Renal/Transplant Research Center, Brigham and Women's Hospital, Boston, MA.
Targeting survival pathways that differentially suppress effector T cells (Teff) while sparing regulatory T cells (Tregs) is key in devising novel tolerogenic protocols in transplantation.…2015 American Transplant Congress
Economic Analysis of Kidney Transplant Tolerance: The Holy Grail Is Less Costly
Transplant Surgery, Massachusetts General Hospital, Boston, MA.
Introduction: Kidney transplantation (KTx), although expensive, is a more cost effective treatment for end-stage renal disease (ESRD) than dialysis, and provides better long term survival…2015 American Transplant Congress
T Cell C5a Receptor (C5aR) Signaling Regulates T Follicular Helper Cell (Tfh) Induction
Translational Transplant Research Center, Icahn School of Medicine at Mount Sinai, New York, NY.
Tfh cells, in part via IL-6 dependent production of IL-21, are specialized providers of B cell help. Extending previous work in which we showed that…2015 American Transplant Congress
Feasibility of Regulatory T Cell Cryopreservation and Banking for Clinical Therapeutic Applications
Feasibility of clinical application of regulatory T cells (Tregs) in clinical transplantation would be improved if Tregs or pre-enriched cells for Treg isolation could be…2015 American Transplant Congress
Microchimerism-Tolerance “Missing Link”: Exosome Acquisition by Host Dendritic Cells
Surgery, University of Wisconsin, Madison, WI.
Background: widespread maternal microchimerism (MMc) in mice is associated with development of immune regulation, which can be used to predict transplantation tolerance. We recently showed…2015 American Transplant Congress
Immune Reconstitution in Recipients of Living Donor Kidney/Hematopoietic Stem + Facilitating Cell Transplants
We report the long-term results from a reduced-intensity nonmyeloablative conditioning approach to establish high levels of donor chimerism without graft-versus-host disease (GVHD) in mismatched related…2015 American Transplant Congress
An Economic Analysis of Tolerance Induction for Two-Haplotype Match Kidney Living Donor Transplant Recipients
1Medicine, Stanford University, Palo Alto, CA; 2Medicine, Baylor College of Medicine, Houston, TX.
Purpose:Tolerance induction is a novel therapy that enables some living donor kidney transplant recipients (LDKTR) to safely discontinue immunosuppressive (IS) therapy. We examine whether tolerance…2015 American Transplant Congress
Peritransplant Costimulation Blockade and Rapamycin Therapy Induces Permanent Limb Allograft Survival
Aim: Using murine models, we sought to identify the mechanisms of responsible for vascularized composite allotransplant (VCA) rejection, and to thereafter, using clinically relevant peri-transplant…2015 American Transplant Congress
IL-33 Enhances Host Tolerance to Candida albicans Kidney Infections Through Induction of IL-13 Production by CD4+ T Cells
Susceptibility to systemic Candida albicans infection is determined not only by immune resistance but also by the ability to control Candida-induced immunopathologies. We previously showed…2015 American Transplant Congress
Eomesodermin Expression By Alloreactive Non-Human Primate CD8+ Memory T Cells: Influence of CTLA4Ig and Regulatory DC Infusion in Renal Allograft Recipients
Background:Memory T cells (Tmem), particularly those resistant to costimulation blockade (CoSB), are considered a major barrier to transplant tolerance. The T-box transcription factor Eomesodermin (Eomes)…
