Characterization of Human Islet Transplant Specific Exosomes in a Xenoislet Transplantation Model.
Department of Surgery, University of Pennsylvania, Philadelphia, PA.
Background: There is a critical need for biomarker platforms for monitoring transplant rejection. We propose that transplant tissues release donor specific exosomes into recipient blood/…2016 American Transplant Congress
Microfluidics to Characterize Leukocyte Trafficking into Allografts and the Resolution of Inflammation.
1Transplant Research Program, Boston Children's Hospital, Boston; 2MGH, Boston.
Pro-resolution mediators such as resolvins and axonal guidance receptor-ligand interactions are increasingly recognized to regulate leukocyte trafficking into sites of inflammation. The implication of this…2016 American Transplant Congress
mTORC2 Negatively Regulates Dendritic Cell (DC) Metabolism and the Allostimulatory Function of Donor DCs in Organ Transplantation.
The mechanistic target of rapamycin (mTOR) is a kinase that functions in at least two complexes: rapamycin (RAPA)-sensitive mTORC1 and RAPA-insensitive mTORC2. These complexes play…2016 American Transplant Congress
Lymph Node Stromal Laminins Differentially Regulate T Cell Immunity and Tolerance.
University of Maryland, Baltimore, MD.
Background:Our recent work demonstrated that laminins α4β1γ1 and α5β1γ1, components of the lymph node (LN) stroma, are differentially regulated. Tolerance is associated with relatively higher…2016 American Transplant Congress
Sphingosine 1-Phosphate (S1P) Receptors Differentially Regulate Murine and Human CD4 T Cell Migration Across Lymphatic Endothelium.
1University of Maryland, Baltimore; 2University of Minnesota, Minneapolis.
S1P and S1PR1 are used by T cells to migrate from thymus across microvascular endothelium to the blood circulation, and across medullary lymphatic endothelium of…2016 American Transplant Congress
Thymus Is Required for T Cells Reconstitution Following Antibody-Mediated Lymphoablation.
Antibody-mediated lymphocyte depletion is used as induction therapy in sensitized transplant recipients. Following lymphoablation, peripheral lymphopenia triggers homeostatic T cell proliferation (HP) and enhanced thymopoiesis.…2016 American Transplant Congress
Role of NRP1 in CD4+ T Cell Allo-Activation.
Department of Surgery, Boston Children's Hospital, Boston, MA.
Introduction: Neuropilin-1 (NRP1) is a transmembrane glycoprotein that functions as a co-receptor for class III/IV semaphorins, VEGF, and several other growth factors. NRP1 has been…2016 American Transplant Congress
Profiling Metabolic Differences Between Graft- vs. Pathogen-Elicited CD8+ T Cell Responses.
The challenge of immune modulation in transplantation is to inhibit pathologic alloreactivity while minimizing off-target toxicities and preserving protective immunity. Data have emerged demonstrating the…2016 American Transplant Congress
Rapamycin Nanotherapy Delays Heart Transplant Rejection.
Background:In patients, allograft survival requires a cocktail of immunosuppressive drugs, while experimentally antibodies targeting the innate immune system have been shown to induce long-term tolerance,…2016 American Transplant Congress
Mechanistic Insights into How Targeting of HDAC10 Promotes Foxp3+ Treg Cell Suppressive Activity, Gene Expression and Metabolism, and Enhances Allograft Survival.
1Children's Hospital of Philadelphia, Philadelphia; 2University of Pennsylvania, Philadelphia.
Foxp3+ T-regulatory (Treg) cells are key regulators of immune responses that can result in unwarranted inflammation and promote allograft rejection. From a theoretical perspective, targeting…
