Sequential Monitoring and Stability of Ex Vivo-Expanded Autologous and Non-Autologous Regulatory T Cells Following Infusion in Non-Human Primates
1University of Pittsburgh, pittsburgh, PA; 2University of Wisconsin, Madison.
Ex vivo-expanded cynomolgus monkey CD4+CD25+CD127- regulatory T cells (Treg) maintained Foxp3 demethylation status at the Treg-Specific Demethylation Region (TSDR), and potently suppressed T cell proliferation…2015 American Transplant Congress
Iron Deficiency Impairs Regulatory T Cell Induction
In a recent clinical trial of immunosuppression withdrawal in adult liver transplant recipients, operational tolerance was associated with development of a transient lymphocyte infiltration rich…2015 American Transplant Congress
Immunomodulatory Effects of Neuropilin-2 On T Cells
Axonal guidance molecules are expressed within the immune system and elicit anti-inflammatory effects with potential to target auto- and alloimmunity. The neuropilin (NRP) family receptors…2015 American Transplant Congress
Leukocyte Associated Immunoglobulin-Like Receptor 1 inhibits Th1 But Enhances Th17 Responses
Background: Leukocyte Associated Immunoglobulin-like Receptor 1 (LAIR1), is a transmembrane receptor expressed by immune cells. It recognizes collagen repeats via its extracellular domain and has…2015 American Transplant Congress
Tracking T Cell Fate After Antithymocyte Globulin (ATG) Immunotherapy in Infant Heart Transplant (HTx) Patients
Polyclonal T cell depletion with ATG is a common induction therapy in adult and pediatric transplantation. In adults, T cell recovery post-ATG involves homeostatic proliferation…2015 American Transplant Congress
The Gut Microbiota Regulates Murine Cardiac Transplant Outcome
1University of Maryland, Baltimore, MD; 2University of Hohenheim, Stuttgart, Germany.
Hypothesis: The gut microbiota regulates systemic immunity. Different characteristics of the microbiota can be defined that have pro- or anti-inflammatory effects. We tested the hypothesis…2015 American Transplant Congress
DEPTOR Is Expressed in CD4+ T Cells and Modulates Effector Responses and Allograft Rejection
Transplant Research Program, Boston Children's Hospital, Boston, MA.
DEPTOR is an evolutionarily conserved, first-in-kind cell intrinsic factor with potential to regulate the activity of multiple intracellular signaling pathways. However, its biology in T…2015 American Transplant Congress
Adoptive Transfer of T Cell Receptor-Transgenic (TCR-Tg) Cells Alters Endogenous Immune Responses During Acute Rejection
University of Chicago, Chicago, IL.
In addition to the therapeutic use of adoptive transfer of T cells to combat viral infections and malignancies in humans, adoptive transfer of T cell…2015 American Transplant Congress
Dramatic Primary Expansion of Indirect CD4 T Cells to Allogeneic APCs In Vivo
An ongoing question regarding the primary allograft response is the relative contribution of the 'direct' (donor MHC-restricted) versus 'indirect' (host MHC-restricted) pathways of T cell…2015 American Transplant Congress
VLA-4 Blockade Inhibits Endogenous Memory CD8 T Cell-Mediated Rejection of Cardiac Allografts
Endogenous memory CD8 T cells infiltrate cardiac allografts within 24 hours of reperfusion and are activated to proliferate and produce IFN-γ in response to donor…
