Immunomodulatory Strategies Directed Towards Tolerance of Vascularized Composite Allografts
Background: Achieving tolerance of vascularized composite allografts (VCAs) would improve the risk-to-benefit ratio in patients who undergo this life-enhancing transplant. Kidney co-transplantation along with a…2015 American Transplant Congress
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
Vaccine-Induced 'Incognito' CD8+ T Cell Memory Can Disrupt Transplantation Tolerance
Transplant recipients harbor immunity to vaccines and pathogens (e.g. CMV, EBV). Pre-existing immunity can have significant antigen-specific ramifications, usually attributed to heterologous immunity, as pathogen-reactive…2015 American Transplant Congress
Glycogen Synthase Kinase 3β Inhibition Promotes Human iTreg Differentiation and Suppressive Function
The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
Induced regulatory T cells (iTregs) are essential to maintain immunological tolerance, immune homeostasis, and prevention of autoimmunity. Some studies suggest that glycogen synthase kinase 3β…2015 American Transplant Congress
Costimulation Blockade Prevents Rejection of Vascularized Composite Allografts
[Background] Vascularized composite allotransplantation (VCA) is an emerging new era in transplant medicine and has become a valid therapeutic option after devastating tissue loss. The…2015 American Transplant Congress
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…
