Abrogating MyD88 Signaling in Donor Lung Resident Hematopoietic Cells Promotes Cell Based Tolerance Induction in Lung Allografts in Mice.
Objectives: MyD88 signaling plays an important role in allograft rejection and tolerance induction. This study is designed to determine the cellular base of MyD88 expression…2017 American Transplant Congress
Recipient iNOS Deficiency Reduces Spontaneous Kidney Allograft Acceptance by Accelerating Allograft Loss.
Center for Transplantation Sciences, Massachusetts General Hospital, Boston, MA
Nitric oxide (NO) production by inducible nitric oxide synthase (iNOS), encoded by NOS2, is a hallmark of the innate immune axis, and is typically associated…2017 American Transplant Congress
Combination Therapy of iNKT Cell Ligand and CD40-CD154 Signal Blockade Establishes Islet Allograft Tolerance in Non-Myeloablative Bone Marrow Transplant Recipients.
Background: Allogeneic islet transplantation is an effective therapeutic option for type 1 diabetes. Toxicity associated with chronic use of immunosuppressants still remains an obstacle for…2017 American Transplant Congress
A Novel Method for iNKT Cell-Mediated Ex Vivo Treg Expansion Applied to Induce Human Transplant Tolerance.
Background: Although regulatory T cells (Tregs) are beneficial for transplant-tolerance induction, decisive methods for their preferential expansion have not yet been established. In our series…2017 American Transplant Congress
Impact of mTOR-Inhibition on Tolerance-Induction Following Heart Transplantation.
Clinic for Cardiac Surgery, Heart Center Leipzig, Leipzig, Germany
Introduction: The mammalian target of rapamycin (mTOR) is a central regulator of the immune system and therefore one target of immunosuppressive drug therapy. Tolerance-inducing properties…2017 American Transplant Congress
Dual Costimulatory Blockades Failed to Achieve Transplant Tolerance Despite Induction of Mixed Chimerism in NHPs.
Background: Our previous studies showed that substantial deletion of CD8+ memory T cells (TMEM) was necessary to induce mixed chimerism (MC) and allograft tolerance when…2017 American Transplant Congress
Suppression of T Cell Proliferation by CpG-Activated B Cells Depends on Granzyme-B and Cell-Cell Contact, but Not on IL-10.
Background: Our previous studies document the potent capacity of regulatory B cells (Bregs) to mitigate allograft immunity. However, we have been largely unsuccessful in demonstrating…2017 American Transplant Congress
The Transcription Factor Batf and IRF1 Controls IL-10/IL-27 Expression in Dendritic Cells and Transplant Tolerance Induction.
Objective: To explore the effect of Batf and IRF1 on IL-10/IL-27 expression in DCs during transplant tolerance induction.Methods: Allogeneic heart transplants were performed between WT…2017 American Transplant Congress
In Depth Characterization of Ex Vivo Expanded Polyclonal Regulatory T Cells Used in a Phase I Clinical Trial Following Kidney Transplantation.
Initial clinical trials have investigated the safety of regulatory T cells (Tregs) as a therapy during aberrant immune activation, like graft-versus-host disease (GVHD) following stem…2017 American Transplant Congress
Applicability and Safety of a Regulatory T Cell Therapy in Adult Liver Transplantation: The “ThRIL” Phase I First-in-Human Trial.
MRC Centre for Transplantation, King's College London, London, United Kingdom
Aim“ThRIL” is a multiple site, open-label, uncontrolled, phase I clinical trial assessing the safety and applicability of a CD4+CD25+FOXP3+ regulatory T cell (Treg) immunotherapy in…
