B Cells in Liver Transplant Tolerance.
In mice liver transplantation, the liver allografts can be accepted across fully mismatched MHC without immunosuppression. After transplantation, T cells infiltrate into the graft in…2017 American Transplant Congress
Deleting LAG-3 Accelerates Cardiac Allograft Rejection and Augments T Cell Memory in Mice.
Purpose: Lymphocyte Activation Gene-3 (LAG-3) expresses a transmembrane receptor on activated immune cells such as T cells, NK cells, and plasmacytoid dendritic cells. It is…2017 American Transplant Congress
Ethylene Carbodiimide Fixed Donor Splenocytes Combined with α-1 Antitrypsin Induce Indefinite Donor Specific Protection to Mice Cardiac Allografts.
Organ Transplant Center, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China
Peritransplant infusion of ethylene carbodiimide fixed donor splenocytes(ECDI-SPs) induces protection of islet and cardiac allografts. However, pro-inflammatory cytokine production during the peritransplantation period may negate…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…
