Assessing the Impact of Flow in Hypothermic Machine Perfusion on Human Venous Endothelium Using a Novel Ex Vivo Model
BACKGROUNDHypothermic machine perfusion (HMP) involves dynamic flow of chilled preservation fluid through an allograft's vasculature. This study describes a simple, reproducible, human model that allows…2018 American Transplant Congress
A Novel Endothelial Cell Based Complement Dependent Cytotoxicity Test in Kidney Transplantation
Introduction:Relevant alloantibodies in kidney transplantation comprise anti-HLA antibodies, blood group antibodies (ABO incompatible) and anti-endothelial cell antibodies (AECA) and can initiate antibody-mediated rejection (ABMR). ABMR…2018 American Transplant Congress
Targeting LTβR Classical NFκB Signaling Facilitates Inflammation Resolution
Background:Contact hypersensitivity (CHS) is a reliable model to assess the immune cell-mediated cutaneous inflammatory response, which includes the three phases of priming/sensitization, elicitation, and resolution,…2018 American Transplant Congress
Apoptotic Exosome-Like Vesicles Induce Endothelial Cell Plasticity
Acute vascular rejection of renal allografts is associated with increased endothelial apoptosis which contributes to the development of transplant vasculopathy. We previously showed that apoptotic…2018 American Transplant Congress
Involvement of PD-L1 Upregulation in Anti-A/B Antibody-Induced Graft Accommodation: Reduction of CD4 T Cell Allo-Response against Graft HLA Class II DR
[Background] Antibodies against transplanted organs cause complement-independent graft injury, but there remain many unknown aspects of its mechanism, in particular its effect on allo-response to…2018 American Transplant Congress
Endothelial Cell Heterogeneity Governs Basal and Inducible Inflammatory Responses Relevant to Allograft Injury
Pathology and Laboratory Medicine, UCLA, Los Angeles, CA.
PurposeTransplanted tissues are differentially susceptible to ischemia/reperfusion and rejection. Endothelial cells (EC) are active regulators of inflammation. But model EC may not adequately reflect the…2018 American Transplant Congress
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…2018 American Transplant Congress
p16INK4a Deletion in Vascular Endothelium Improves Kidney Regeneration Post Ischemia Reperfusion Injury
Background: Ischemia Reperfusion injury (IRI) mediated cellular senescence in kidney allografts has been linked to a loss in regenerative potential and delayed graft function. Injured…2018 American Transplant Congress
Endothelin A Receptor (ETaR) siRNA Ameliorates Renal Ischemia Reperfusion Injury through Upregulating Expression of eNOS in Rats
Aims: To explore the protective effect of Endothelin A Receptor (ETaR) siRNA on renal ischemia reperfusion injury and its underlying mechanism.Methods: The model of unilateral…2018 American Transplant Congress
Novel Function of TIE2 in Immunoregulation
Transplant Research Program, Boston Children's Hospital, Boston, MA.
The immunogenicity of graft microvascular endothelial cells (ECs) has immense biological significance in the modulation of the local intragraft microenvironment. EC may either support Teffector…
