Extra-Renal Cardiac Injury Is Associated with Upregulation of NOD2 and Nlrp3 in the Heart After Renal IRI.
Medicine, Division of Nephrology and Hypertension, University of California San Diego, La Jolla, CA
Background: Recent studies show renal ischemia reperfusion injury (IRI) is associated with systemic release of danger associated molecular patterns (DAMPs). DMAPs induce significant extra-renal organ…2017 American Transplant Congress
Binding of Antigens by Its Specific Antibodies Results in Exosome Formation Leading to Rejection of Syngeneic Murine Cardiac Grafts.
Norton Thoracic Institute, St. Joseph's Hospital and Medical Center, Phoenix
Background: Antibody binding to its antigen can activate complement cascades leading to cell death. In addition, it can activate intracellular signals leading to rejection of…2017 American Transplant Congress
Extracellular Mitochondria Cause B7 Costimulation Blockade Resistant Allograft Rejection in Mice.
1Surgery, Duke University, Durham, NC; 2Immunology, Duke University, Durham, NC
Introduction: Mitochondria released in the setting of tissue injury and cell death are a source of damage-associated molecular patterns that activate innate immune responses. We…2016 American Transplant Congress
A Novel Humanized Mouse Model Incorporating Non-Fetal Tissue.
Surgery/Transplant Division, University of Wisconsin-Madison, Madison, WI.
Pre-clinical research into allogeneic tissue transplantation therapies, as well as patient-specific regenerative medicine studies, require animal models that closely mimic the typical patient's immune response.…2016 American Transplant Congress
Activation of Innate Immunity During Human OLT-IRI Triggers Adaptive Immunity and Correlates with the Degree of IRI Injury.
1Surgery, Dumont-UCLA Transplant Ctr, Los Angeles, CA; 2Pathology, UCLA, Los Angeles, CA.
Ischemia reperfusion injury (IRI) in orthotopic liver transplantation (OLT) can severely compromise graft and recipient survival. We postulate this is mediated by interactions between the…2016 American Transplant Congress
Optimizing the Immunogenicity and Immunomodulatory Properties of MSC for Cellular Therapy.
Mesenchymal stromal cells (MSC) are candidates for immunotherapy after transplantation. MSC have shown to be immunomodulatory and low immunogenic, which is favorable for cellular therapy…2016 American Transplant Congress
Dendritic Cells and Damage-Associated Molecular Patterns in Aging.
Recently, it has been shown that Dendritic Cells (DCs) of old organs accelerate graft rejection by orchestrating IL-17A-mediated T cell responses. Moreover, cell-free DNA has…2016 American Transplant Congress
Biopsy-Proven Rejection in Children After Liver Transplantation Is Associated by an IL-12p40-Mediated Innate Immune Response Followed by Th1 T Cell Activation.
Sustained by adaptive immune cells and their soluble mediators is well established for infection but it has not been demonstrated for solid organ transplantation in…2016 American Transplant Congress
Potent Induction Therapy Improves Graft Outcome in Younger Pancreas Transplant Recipients (<30 Years of Age).
SUNY Upstate Medical University, Syracuse, NY.
Purpose: Pancreas transplants (tx) are increasingly performed in older patients with type 1 diabetes mellitus. This trend may be explained by the significantly higher immunologic…2016 American Transplant Congress
Assessing Return of CMV Specific Cellular Immunity Using the T-SPOT.CMV Soon After Kidney Transplant with Thymoglobulin.
Infectious Disease, Massachusetts General Hospital, Boston, MA.
Background: We do not currently have sufficient predictive tools to determine risk of CMV infection after organ transplantation. Recent data suggest that assays of the…
