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
A Unique In Vitro Migration Model for Leukocyte Trans-Lymphatic Endothelial Migration.
1University of Maryland, Baltimore; 2University of Minnesota, Minneapolis.
Trans-endothelial migration (TEM) is an essential process for leukocyte circulation. While much is known about lymphocyte blood to tissue migration, far less is known about…2016 American Transplant Congress
Cold Storage Stabilization of Gap Junctions Reduces Post Transplant Ischemia Reperfusion Injury.
Purpose: Organ procurement, cold storage and ischemia reperfusion injury (IRI) promote inflammation, which induces endothelial cell (EC) activation and dysfunction post transplantation. EC gap junctions…2016 American Transplant Congress
HLA Antibody Clonality and Epitopes Dictate Complement Activation.
Background: Alloimmunization results in production of polyclonal donor specific antibodies (DSA) against human leukocyte antigens (HLA), which mediate endothelial cell activation, leukocyte recruitment, and complement…2015 American Transplant Congress
Tandem P-Selectin Glycoprotein Ligand-Immunoglobulin (TSGL-Ig) Protects Liver Endothelial Cells Against Prolonged Cold Preservation Injury in Mouse Liver Transplantation
Background: Liver endothelial cell (LEC) damage is central in the pathogenesis of hepatic ischemia-reperfusion injury (IRI). LEC detachment/progressed denudation are typical during cold storage and…2015 American Transplant Congress
Allogeneic MonocyteEndothelial Cell Interaction Plays a Critical Role in Initiating Early Pro-Fibrosis Responses
Surgery, Duke University Medical Center, Durham, NC.
Chronic allograft nephropathy (CAN), characterized by interstitial fibrosis, vascular intimal thickening, and glomerulosclerosis, has remained as leading cause of allograft failure. The role of innate…2015 American Transplant Congress
Lymphotoxin Controls Treg Interactions With Lymphatic Endothelial Cells and Interstitial Migration In Vivo
University of Maryland, Baltimore, MD.
Introduction: Lymphotoxin (LT) coordinates the development, organization and structure of lymphoid organs, and LTβreceptor (LTβR) is involved in thymocyte migration. However, LT has no described…2015 American Transplant Congress
Monocyte Recruitment to HLA Class I Antibody-Activated Endothelial Cells Is Dependent Upon mTOR
Pathology & Laboratory Medicine, UCLA, Los Angeles, CA.
Aim: Antibody-mediated rejection (AMR) persists as a major issue affecting solid organ transplants. The purpose of this study was to investigate the proximal signaling events…2015 American Transplant Congress
Pro-Inflammatory Actions of New Non-HLA Antibodies Targeting Protease-Activated Receptor (PAR-1)
Microvascular endothelium is major target for antibodies directed against HLA and non-HLA antigens. Functional antibodies targeting G-protein coupled receptors (GPCRs) such as AT1R or ETAR…2015 American Transplant Congress
Use of RNA Sequencing for Discovery of Markers of Accommodation in Surveillance Biopsies from Recipients of an ABO-Incompatible Renal Transplant
Recipients of an ABO incompatible transplant have circulating anti-AB antibodies, A and/or B antigens expressed on endothelium and usually C4d deposition on the endothelium, yet…
