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…2017 American Transplant Congress
Novel Cell Intrinsic Role of the Adaptor Protein TSAd in Maintaining Alloimmune T Regulatory Cell Function.
TSAd is an SH2 domain containing intracellular adapter molecule that functions to elicit T cell receptor-mediated signals and cytokine production. TSAd knockout (KO) T cells…2017 American Transplant Congress
Role of Chemokines in Resolution of BK Virus-Associated Nephropathy and Chronicity of Pathology Changes in Kidney Transplant Recipients.
David Geffen School of Medicine at UCLA, Los Angeles, CA
BK virus-associated nephropathy (BKN) remains the most common infectious cause of allograft loss after kidney transplantation. We previously demonstrated increased frequency of polyfunctional T cells…2017 American Transplant Congress
IL-3 Contributes to Development of Basophil-Triggered Cardiac Allograft Fibrosis Development.
Introduction: Organ fibrosis and vasculopathy are major causes of chronic cardiac allograft failure. Resident (donor-derived) fibroblasts are thought to be mainly responsible for excessive production…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.…2017 American Transplant Congress
Low Level Light Laser Treatment Reduces Macrophage Retention and ROS Levels Following Tissue Injury.
1University of Illinois, Chicago; 2Rush University, Chicago
Following ischemia reperfusion injury, inflamed macrophages switch from oxidative phosphorylation to glycolysis; in contrast, macrophages associated with tissue repair rely on oxidative phosphorylation. The triggers…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
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,…2016 American Transplant Congress
Tissue Inhibitor of Metalloproteinase-3 (TIMP-3) Protects Against Loss of Hepatic Integrity After Ischemia-Reperfusion Injury.
Surgery, The Dumont-UCLA Transplant Center, Los Angeles, CA.
Liver ischemia-reperfusion injury (IRI) remains a challenging problem in clinical orthotopic liver transplantation (OLT). Tissue inhibitor of metalloproteinases-3 (TIMP-3) is an extracellular matrix (ECM)-associated protein…2016 American Transplant Congress
Microfluidics to Characterize Leukocyte Trafficking into Allografts and the Resolution of Inflammation.
1Transplant Research Program, Boston Children's Hospital, Boston; 2MGH, Boston.
Pro-resolution mediators such as resolvins and axonal guidance receptor-ligand interactions are increasingly recognized to regulate leukocyte trafficking into sites of inflammation. The implication of this…
