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…2018 American Transplant Congress
CD4 T Cells Require Both S1PR1 and S1PR4 for Afferent Lymphatic Migration
1UMB, MD; 2NIH, MD; 3Boston Children's Hospital, MA; 4NYU, NY; 5U. Minnesota, MN.
Introduction: Sphingosine 1-phospate (S1P) receptor 1 (S1PR1) drives T cell migration from thymus into blood, and lymph nodes (LN) into efferent lymphatics. Whether S1PR1 and…2018 American Transplant Congress
Lymphatic Endothelium Requires S1PR2 for T Cell Transendothelial Migration
1UMB, MD; 2NIH, MD; 3Boston Children's Hospital, MA; 4NYU, NY; 5U. Minnesota, MN.
Introduction: Sphingosine 1-phosphate (S1P) receptors 1 (S1PR1) and S1PR2 are highly expressed by lymphatic endothelial cells (LEC), while T cells express S1PR1 and S1PR4. S1P…2018 American Transplant Congress
Lymphotoxin Beta Receptor Modulation in Lymphatic Endothelial Cells Alters Regulatory T Cell Dynamics
Background:Lymphotoxin beta receptor (LTβR) mediated signaling in lymphatic endothelium cells (LEC) is important for migration of regulatory T cells (Treg) to afferent lymphatic vessels (LV)…2018 American Transplant Congress
Double Deficiency of Gelatinase-A and Gelatinase-B Does Not Protect against Hepatic Ischemia Reperfusion Injury
Dumont-UCLA Transplant Center, Los Angeles.
Gelatinases, consisting of gelatinase A (MMP-2; 72 KDa) and gelatinase B (MMP-9; 92KDa), are a subgroup of matrix metalloproteinases (MMPs) with key roles in a…2018 American Transplant Congress
Endothelial Progenitor Cell-Derived Extracellular Vesicles Inhibit Kidney Ischemia-Reperfusion Injury through the Transfer of Specific microRNA and mRNA Coding for the Complement Inhibitors CD55, CD59, Factor H and for the Transcription Factor NRF2: Relevance for Delayed Kidney Graft Function
Complement activation and oxidative cell damage are hallmarks of delayed kidney graft function (DGF) due to ischemia-reperfusion injury (IRI). Endothelial progenitor cells (EPC) protect from…2017 American Transplant Congress
Uptake of Extracellular Mitochondria Activates Human Endothelial Cells That Stimulate Alloreactive Effector T Cell Responses.
1Surgery, Duke University, Durham, NC; 2Immunology, Duke University, Durham, NC
Introduction: Vascular endothelial cells (VECs), the initial barrier between host immunity and donor allograft tissue, play a critical role in allograft rejection. We investigated the…2017 American Transplant Congress
Effects of Anti-HLA Antibodies on Endothelial Expression and Serum Levels of Thrombomodulin in Kidney Recipients.
Medicine, Universite Laval, Quebec, QC, Canada
Background: Thrombomodulin (TBM) is an anticoagulant and anti-inflammatory protein expressed on endothelial cells (ECs). Mutations of TBM are seen in thrombotic microangiopathies due to aHUS.…2017 American Transplant Congress
Thrombalexin: Use of a Cytotopic Anticoagulant to Reduce Thrombotic Microangiopathy in a Highly Sensitized Model of Kidney Transplantation.
Introduction:Thrombotic microangiopathy (TMA) is a phenomenon observed in antibody-mediated rejection (AMR) of the kidney transplant, particularly in highly sensitized individuals. Following promising data in a…2017 American Transplant Congress
Anti-HLA I Antibody Enhances Endothelial Cell-Induced Polarization of Human Monocytes to M2a/c-Like Macrophages.
HLA antibody (Ab)-mediated rejection (AMR) is often characterized by graft-infiltrating macrophages, which correlate with tissue fibrosis. Recent studies suggest they may mainly represent M2-polarized macrophages.…
