Blocking MHC Class II on Human Endothelium Mitigates Acute Rejection of Vessel Allografts by Effector Memory T Cells.
Acute allograft rejection is mediated by alloreactive CD8+ T cells that differentiate into cytotoxic lymphocytes (CTL). In most rodent models, CTL differentiate from naïve CD8+…2016 American Transplant Congress
Pathogenic Role of Anti-HLA Antibodies on Endothelial Progenitor Cell Dysfunction of Highly Sensitized Kidney Transplanted Patients.
Anti-HLA antibodies (abs) bind to kidney graft endothelial cells inducing complement-mediated injury and humoral rejection. Endothelial Progenitor Cells (EPC) are bone marrow-derived precursors able to…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
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…2016 American Transplant Congress
Lysosome Ativity Regulates LG3 Export by Apoptotic Cells.
LG3, a C-terminal fragment of perlecan bioactive on vascular cells, has been implicated in aggravation of renal allograft rejection and vascular injury. Recently, we have…2016 American Transplant Congress
Vascular Endothelial Cell Activation by Mitochondria Links Innate and Adaptive Immune Responses to Allograft Injury.
Surgery, Duke University Medical Center, Durham, NC.
Vascular endothelial cells (ECs) are an initial barrier between allografts and the host immune system and play an important role in initiating allograft rejection. Increasing…2016 American Transplant Congress
Tacrolimus as a Tool for Intracellular Assessment of von Willebrand Factor Production by Activated Human Glomerular Endothelial Cells.
Renal Division, University Health Center (CHU) of Quebec, Laval University, Quebec, QC, Canada.
Background: Von Willebrand factor (vWF) is a prothrombotic mediator stored in intracytoplasmic granules within endothelial cells and is released by endothelial exocytosis, leading to microangiopathic…2016 American Transplant Congress
Matrix Metalloproteinase-2 (MMP-2) Activity Protects Against Hepatic Ischemia Reperfusion Injury Through MMP-9-Dependent and MMP-9-Independent Mechanisms.
The Dumont-UCLA Transplant Center, Los Angeles.
Matrix Metalloproteinases (MMPs) are a family of proteinases with key roles in tissue homeostasis, inflammation and repair. We have recently shown that MMP-9 and MMP-2,…
