Six Year Follow-Up of a Phase 2 Clinical Trial to Induce Tolerance in Mismatched Living Donor Renal Transplant Recipients
27 subjects have been transplanted in a phase 2 protocol (IDE 13947) based upon tolerogenic CD8+/TCR- facilitating cells (FCRx) and 200 cGy TBI-based nonmyeloablative conditioning…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
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
Identifying the Operational Tolerant Pediatric Liver Transplant Recipient by Cytometry by Time-of-Flight
Liver allografts are known to be well tolerated and indeed, some recipients of liver allografts retain stable graft function in the absence of immunosuppression. The…2015 American Transplant Congress
Repurposing Jak/STAT Signaling Inhibition to Enhance Costimulation Blockade and Promote Transplant Acceptance
Plastic and Reconstructive Surgery, Johns Hopkins University, Baltimore.
PURPOSE: Transplant tolerance induction through conventional costimulation blockade (CoB) remains an elusive goal. Recent evidence suggests that inflammatory cytokines contribute to the activation of alloreactive…2015 American Transplant Congress
Rational Development of Alloantigen Specific Regulatory T Cell Therapy Requires Insight Into Longevity of Alloimmune Pathways
University of Cambridge, Cambridge, United Kingdom.
IntroductionWe have recently demonstrated that indirect-pathway responses against different alloantigens differ in their strength and longevity; specifically, that indirect responses against MHC class I alloantigen…2015 American Transplant Congress
IL-2/IL-2 Ab Complex Leads to Long-Term Tolerance in a Treg Dependent DST Model of Skin Allograft Transplantation in Which DST and Timing of the Antibody Complex Are Crucial
1Children's Hospital at Westmead, Sydney, Australia; 2Garvan Institute, Sydney, Australia.
Background: In vivo Treg expansion using IL2 complexed with anti-IL2 antibody has been demonstrated to be effective in the induction of long-term acceptance of islet…2015 American Transplant Congress
Donor Specific Expansion of Regulatory T-Cells Was Associated With Allograft Tolerance Induced By Transient Mixed Chimerism in Nonhuman Primates
Transplant Center, Massachusetts General Hospital, Boston, MA.
Background: We have previously reported successful induction of solid organ allograft tolerance in nonhuman primates (NHP) via a mixed chimerism approach. Since these recipients achieved…2015 American Transplant Congress
Tolerance to Graft A-Antigens Following ABO-Incompatible Heart Transplantation (HTx) in a Blood Group A-Transgenic Mouse Model
Purpose: ABOi HTx can be performed safely in infants when ABO antibody (Ab) levels are low or absent. Following ABOi HTx, immune tolerance develops to…2015 American Transplant Congress
Regulatory Tolerance Across a Full MHC Barrier Is More Robust Than Tolerance Across a Class I MHC Disparity Alone
Background: We previously demonstrated that tolerance of hearts and/or kidneys achieved across a class I MHC mismatch with 12 days of CyA can be abrogated…
