Targeting Lymphotoxin Signaling in Lymphatics Regulates Immune Sensitization, Elicitation, and Resolution
Background:Contact hypersensitivity (CHS) is a T cell-mediated cutaneous inflammatory response which includes three phases of priming/sensitization, elicitation, and resolution,mirroring many aspects of allogeneic responses. The…2018 American Transplant Congress
p16INK4a Deletion in Vascular Endothelium Improves Kidney Regeneration Post Ischemia Reperfusion Injury
Background: Ischemia Reperfusion injury (IRI) mediated cellular senescence in kidney allografts has been linked to a loss in regenerative potential and delayed graft function. Injured…2018 American Transplant Congress
Endothelin A Receptor (ETaR) siRNA Ameliorates Renal Ischemia Reperfusion Injury through Upregulating Expression of eNOS in Rats
Aims: To explore the protective effect of Endothelin A Receptor (ETaR) siRNA on renal ischemia reperfusion injury and its underlying mechanism.Methods: The model of unilateral…2018 American Transplant Congress
Novel Function of TIE2 in Immunoregulation
Transplant Research Program, Boston Children's Hospital, Boston, MA.
The immunogenicity of graft microvascular endothelial cells (ECs) has immense biological significance in the modulation of the local intragraft microenvironment. EC may either support Teffector…2018 American Transplant Congress
Re-Endothelialization of Liver Xenografts Utilizing Human Endothelial Cells
1Surgery, University of Maryland, Baltimore, MD; 2Pathology, University of Maryland, Baltimore, MD.
Introduction:Acute antibody mediated rejection due to preformed antibodies present in human serum remains a hurdle to successful xenotransplantation. Xenograft vascular endothelium represents the initial site…2018 American Transplant Congress
Recombinant Thrombomodulin alpha Attenuates Kidney Graft Damage after Long Cold Ischemia Time in a Rat Kidney Transplant Model
Objectives: Thrombomodulin (TM) extensively expresses on the endothelial cells in the steady state and is known to prevent hypercoagulation via combining with thrombin and inactivating…2018 American Transplant Congress
Ultrastructural Changes in Lung Allografts: Endothelial Changes Correlate with Donor Specific Antibody & Antibody Mediated Rejection
Introduction: Antibody mediated rejection (AMR) causes lung allograft (LA) injury. Challenges with C4d interpretation & lack of specific histological criteria account for difficulty in diagnosing…2018 American Transplant Congress
Rapamycin Impairs Human Endothelial Cell Alloimmunogenicity Independent of PD-1/PD-1 Ligand Inhibitory Signaling
Department of Surgery, Duke University Medical Center, Durham, NC.
Rapamycin prevents costimulation blockade (CoB)-resistant rejection in mice and primates, and early human data suggests a similar salutary effect. We have hypothesized that one mechanism…2018 American Transplant Congress
Treg Regulate Distinct Lymphatic NFκB Signaling Pathways to Alter Migration and Immunity
Background: Treg migration to the graft and draining lymph nodes is crucial for graft survival. Little is known about the molecular cues that regulate the…2018 American Transplant Congress
CD40 Signaling in Proximal Tubules Regulates Fibrosis in Both Hypertension and Chronic Allograft Rejection
University of Toledo College of Medicine and Life Sciences, Toledo, OH.
Background: We explored the role of CD40 signaling in kidney proximal tubule epithelial cells on renal interstitial fibrosis (IF) in two models: hypertension; and chronic…
