Negative Effects of Being Obese or Overweight on T Regulatory (Treg) Cell Suppressive Function in Patients Listed for Lung Transplantation (Tx)
Aim: Obese and overweight patients may be prone to adverse outcomes following lung Tx. We sought to determine the relationship between body mass index (BMI)…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
Kidney Plasmacytoid Dendritic Cells Display Distinct Cell Surface Markers and May Explain the Induction of Tolerance by Kidney Allografts
Massachusetts General Hospital, Boston, MA.
Achieving tolerance in heart allografts is an important area of research as the need for heart transplantations increase. Recent studies in non-human primates (NHPs) have…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…2015 American Transplant Congress
Operational Tolerance in Kidney Transplantation: Results of a Europe-Wide Survey
BACKGROUND: Operational Tolerance (opTOL) is deemed to be extremely rare in kidney transplantation. We launched a Europe-wide survey to assess the frequency of opTOL.METHODS: 18…2015 American Transplant Congress
Comparison of T Regulatory (Treg) Cell Function Pre- and Post-Lung Transplantation Shows a Major Negative Impact of Immunosuppression on Treg Function
Aim: Clinical lung Tx recipients do not have sustained long-term survival outcomes comparable to that of other recipients of solid organ allografts, despite generally comparable…2015 American Transplant Congress
Donor Specific Expansion of Regulatory T-Cells Was Associated With Allograft Tolerance Induced By Transient Mixed Chimerism in Nonhuman Primates
Transplant Center, Massachusetts General Hospital, Boston, MA.
Background: We have previously reported successful induction of solid organ allograft tolerance in nonhuman primates (NHP) via a mixed chimerism approach. Since these recipients achieved…2015 American Transplant Congress
Effects of Toll Like Receptor (TLR) Signaling on Murine Alloimmunity Are Modulated by Immune Cell Derived Complement
TLR signals prevent CD40L-blockade (MR1) induced murine transplant tolerance but mechanisms are incompletely understood. Based on previous findings that immune cell derived complement activation products…2015 American Transplant Congress
Thymic Transplantation to Determine Mechanisms of Thymic Involution: Insulin-Like Growth Factor 1 Receptor and Forkhead Box Protein N1 in the Thymus Play a Role in Maintaining the Juvenile Thymus
Thymic involution has long been associated with age-related changes of the immune system, although the cause remains unclear. We have extensively studied the role of…2015 American Transplant Congress
Anti-BTLA Antibody (6B2) Induced Prolongation of Fully MHC-Mismatched Murine Cardiac Allograft and Generation of Foxp3+ Regulatory T Cells
Background: The co-inhibitory receptor B and T lymphocyte attenuator (BTLA; CD272) has been implicated in the regulation of autoimmune and may potentially play an important…
