Ex Situ Heart Perfusion and Standard of Care Cold Storage Differentially Affect the Ischemic Secretome of Donor Hearts in Perfusates but Not the Reperfusion Response in Recipient Plasma
*Purpose: Various allograft preservation procedures influence the donor organ status that may be reflected by the cytokine/chemokine microenvironment in heart transplant (HTx) recipients. In addition,…2021 American Transplant Congress
Myeloid Foxo1-β-catenin Axis Regulates Hedgehog/Gli1 Signaling and Controls NLRP3-Mediated Innate Immune Responses in Sterile Inflammatory Liver Injury
Surgery, Dumont - UCLA Transplant Center, Los Angeles, CA
*Purpose: Foxo1 plays important roles in cell metabolism, oxidative stress, inflammation, and apoptosis. Activation of Hedgehog/Gli1 signaling regulates cell growth, differentiation, and immune function. However,…2021 American Transplant Congress
CHBP Induces Stronger Immunosuppressive CD127+ M-MDSC via Erythropoietin Receptor
Urology, Zhongshan Hospital, Fudan University, Shanghai, China
*Purpose: Erythropoietin (EPO) is not only an erythropoiesis hormone, but also an immune regulatory cytokine. The receptors of EPO, (EPOR)2 and tissue protective receptor (TPR),…2021 American Transplant Congress
Peripheral Blood Inflammatory Chemokines Uncover Rejection in the Absence of Histological Lesions
*Purpose: Cytokines and chemokines play a critical role in the pathophysiology of allograft rejection, but the relation of peripheral blood cytokine expression profiles to clinical…2021 American Transplant Congress
IL-10 Signaling in T Cells Modulates Costimulation-independent Activation and is Essential for Transplant Tolerance Induction
*Purpose: Costimulation blockade (CoB)-based immunotherapy remains a very promising approach for better management of transplant recipients. Understanding the mechanisms that impact the efficacy of CoB…2021 American Transplant Congress
Propensity Matched Analysis of Death and Non-favorable Discharge Among Hospitalized Transplant Recipients with COVID-19
1Houston Methodist Research Institute, Houston, TX, 2Houston Methodist Hospital, Houston, TX
*Purpose: This study compared death and non-favorable discharge following a hospital admission for Coronavirus Disease 2019 (COVID-19) management for patients with a history of solid…2021 American Transplant Congress
HLA Mismatching and Subclinical Inflammation: An Association to be Considered in Kidney Transplant Patients with Low Immunological Risk
*Purpose: Subclinical inflammation (SCI) (2021 American Transplant Congress
Impact of COVID-19 on Solid Organ Transplantation
*Purpose: Patterns of racial disparities have been identified throughout the history of American medicine. In December 2019, COVID-19 was first detected and has had a…2021 American Transplant Congress
Transgenic Overexpression of Human Ectonucleoside Triphosphate Diphosphohydrolase 1 (entpd1, Or Hcd39) in Pig to Primate Xenotransplantation Models
*Purpose: Human CD39 (hCD39) is the gene of interest in xenotransplantation due to its reported capacity to prevent platelet aggregation by metabolizing extracellular ATP to…2021 American Transplant Congress
Resolution of Endothelial Inflammation is Delayed Following IFNγ, Which Provokes a Long-lasting Pro-adhesive Phenotype Dependent on JAK/STAT Signaling
Pathology and Laboratory Medicine, UCLA, Los Angeles, CA
*Purpose: Although many cytokines are upregulated within allografts undergoing rejection, intragraft transcripts are dominated by IFN-response signatures. Resolution is a key phase of inflammation needed…
