Gsk3β Regulates Macrophage Pro-Inflammatory Immune Activation via AMPK-Mediated Induction of Small Heterodimer Partner (SHP).
Background & AimsAlthough glycogen synthase kinase 3 β (Gsk3β) has been found to play key roles in ischemia and reperfusion injuries (IRI) of different organs,…2016 American Transplant Congress
Recapitulating Peripheral T Cell Development in Neonatal Mice to Induce Transplant Tolerance.
University of Alberta, Edmonton, Canada.
Purpose: Neonatal mice are susceptible to tolerance induction with semi-allogeneic bone marrow and spleen cells (BMC/SC) while allogeneic BMC/SC cause acute lethal graft-versus-host disease (GVHD).…2016 American Transplant Congress
Direct IL-33 Stimulation of T Regulatory Cells via Suppression of Tumorigenicity 2 (ST2) Is Required for Effective Control of Alloimmune Responses.
Background: IL-33 is a pleotropic cytokine that can protect against cardiac transplant rejection by expanding regulatory T cells (Treg), particularly a Treg subset expressing the…2016 American Transplant Congress
Macrophage Specific Deletion of RhoA Impedes Macrophage Functions and Abrogates Chronic Rejection of Cardiac Allograft.
Surgery, The Houston Methodist, Houston, TX.
Objective. Chronic rejection of transplanted organs remains the main obstacle in the long-term success of organ transplantation. Chronic rejection occurs in 40-45% of recipients at…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
Neonatal Tolerance: Donor and Host Cells Fuse in Livers of Newborn Mice Injected With F1-Bone Marrow/Spleen Cells
University of Alberta, Edmonton, Canada.
Purpose: Multiple liver cell-types induce immunological tolerance. Indeed liver allografts are often spontaneously accepted in humans and mice. The role of host liver in the…2015 American Transplant Congress
Presence of Donor Leukocytes and Donor MHC-Cross-Dressed Recipient Cells and Its Relationship to Direct T Cell Alloresponses After Allotransplantation
We have studied the kinetics of donor cell trafficking from the graft to recipient's lymphoid organs and its correlation to the direct T cell alloresponse…2015 American Transplant Congress
Activated Protein C Treatment Protects Steatotic and Non-Steatotic Livers Under Ischemia–Reperfusion Injury in Different Manner
Activated protein C (APC) is known to have the cytoprotective effect on liver ischemia–reperfusion injury (IRI) in rat models. However, it is unclear that whether…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
ECDI Fixed Donor Splenocytes Combined With α-1 Antitrypsin Induce Immune Tolerance in Mice Cardiac Transplantation Model
Our previous study have shown that infusions of donor splenocytes fixed with 1-ethyl-3-(3'-dimethylaminopropyl)-carbodiimide (ECDI-SPs) could prolong allografts survival in mice cardiac transplantation model. However, proinflammatory…
