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,…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…2015 American Transplant Congress
Interactions Between Platelets and Liver Sinusoidal Endothelial Cells Initiate Liver Regeneration
ObjectivesPlatelets and liver sinusoidal endothelial cells (LSEC) were shown to be important contributors to liver regeneration. Several recent studies suggested that their interactions might be…2015 American Transplant Congress
The 20S Proteasome Is Active in Apoptotic Nanovesicles and Controls Anti-LG3 Antibody Production
Humoral autoreactivity to apoptotic cells and perlecan/LG3, a proteoglycan fragment released by apoptotic cells, predicts poor allograft outcomes in renal transplant patients. How apoptotic cells…2015 American Transplant Congress
Anti-LG3 Antibodies Aggravate Ischemia-Reperfusion Injury
Ischemia-Reperfusion Injury (IRI) is a significant cause of renal allograft dysfunction and a risk factor for poor long-term graft outcomes. Microvascular injury is an important…2015 American Transplant Congress
mTOR Inhibitors Reduce the Endothelial Transmigration of Leukocytes After Ischemia
ObjectivemTOR inhibitors Everolimus and Sirolimus are currently used as maintenance immunosuppressive agents to prevent rejection of solid transplanted organs. Episodes of transplant rejection and graft…
