IL23R is a Pathogenic Gene in Type 1 Regulatory T Cells during Mouse Cardiac Transplantation Models
IL23R has been confirmed to be a pathogenic gene in Th17 cells. However, its role in type 1 regulatory T cells (Tr1 cells) is not…2017 American Transplant Congress
Inhibition of Liver Natural Killer Cells Activation Through Co-Transplantation of Pre-Activated Mesenchymal Stem Cells Contributes to Improvement of Islet Graft Survival.
Department of Gastroenterological and Transplant Surgery, Hiroshima University, Hiroshima, Japan
Introduction: We have previously reported that enhancement of TNF-related apoptosis-inducing ligand (TRAIL)-mediated liver NK-cell activity after intraportal islet transplantation (IT) inhibits engraftment of islets. Recently,…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
Liver Transplantation Tolerance Using Outbred Mice.
Success of organ transplantation currently depends on life-time immunosuppression, resulting in severe side effects. Induction of donor specific tolerance is ideal, which actually spontaneously occurs…2017 American Transplant Congress
Inhibition of Multiple Nodes in the PI3K/Akt/mTOR Pathway Synergistically Suppresses Epstein-Barr Virus B Cell Lymphomas.
Division of Abdominal Transplantation, Stanford School of Medicine, Palo Alto, CA
Treating post-transplant lymphoproliferative disorders (PTLD) remains a clinical challenge due to adverse effects such as graft rejection. mTOR inhibitors, including rapamycin (RAPA), have shown both…2017 American Transplant Congress
mTORC1 and 2 Regulate Dendritic Cell (DC) Metabolism and Allostimulatory Function of Donor DCs in Skin Transplantation.
Background/Hypothesis: The mechanistic target of rapamycin (mTOR) is a kinase that functions in two complexes: rapamycin (RAPA)-sensitive mTORC1 and RAPA-insensitive mTORC2. These complexes play critical…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
Donor SIRPa Polymorphism Modulates the Innate Immune Response to Allogeneic Grafts.
Mice devoid of T, B, NK, and innate lymphoid cells distinguish between self and allogeneic non-self despite the absence of an adaptive immune system. 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
Combining Neural Stem Cell Transplantation with Mixed Hematopoietic Chimerism Promotes Restoration of Self-Tolerance in Established Experimental Autoimmune Encephalomyelitis.
Surgery, Massachusetts General Hospital, Boston, MA
Multilineage mixed hematopoietic chimerism induces tolerance to alloantigens in rodents, large animals and kidney-transplanted patients. Here we combined mixed chimerism with neural stem cell (NSC)…
