Optimization of Human Liver Organoid Model for Nonalcoholic Fatty Liver Disease and Nonalcoholic Steatohepatitis
*Purpose: The aim of our project is to develop an in vitro 3D human liver organoid (3D-HLO) model for studying nonalcoholic fatty liver disease (NAFLD)…2022 American Transplant Congress
CEACAM1 Splice Isoforms Are Regulated by Hypoxia Inducible Factors 1 alpha (HIF-1a) to Protect Against Ischemic Injury in Mouse and Human Liver Transplantation
*Purpose: CEACAM1 (CC1) is a transmembrane glycoprotein that undergoes extensive alternative splicing (AS) to generate CC1-S and CC1-L. It is currently unclear which of these…2022 American Transplant Congress
Hepatocyte SIRT1 Regulation of Apoptosis-Mediated Pyroptosis Cell Death in Mouse and Human Liver Transplantation
1UCLA Medical Center, Los Angeles, CA, 2NIEHS, Durham, NC
*Purpose: Cold static preservation is a gold-standard in orthotopic liver transplantation (OLT). However, the role of hepatocyte-specific SIRT1 transcriptional regulation of cell death programs during…2021 American Transplant Congress
Hepatocyte SIRT1 Suppresses Atf4-mediated Apoptosis Triggered by Cold Stress in Mouse and Human Liver Transplantation
1Dumont-UCLA Transplant Center, Los Angeles, CA, 2NIEHS, Durham, NC
*Purpose: The role of ER-stress or hepatocyte-specific SIRT1 signaling during donor liver cold preservation remains unknown. We employed a mouse OLT model and analyzed clinical…2021 American Transplant Congress
Invariant Nkt Cells Promote Expansion of Novel Cxcr3+Ccr4+Cd8+ T Cells in the Liver Following Allogeneic Hepatocyte Transplant
*Purpose: Hepatocyte transplantation represents a treatment for metabolic diseases and a bridge therapy to whole organ transplant but is limited in part by cell immunogenicity.…2021 American Transplant Congress
Ectopic Hepatocyte Transplantation Into the Lymph Nodes in a Fully Mismatched Allogeneic Dog Model Using Tacrolimus and Prednisone
*Purpose: Develop organogenesis through ectopic hepatocyte transplantation (HT) into the upper abdominal lymph nodes (LN).*Methods: Three groups of Mongrel dogs weighting between 25-35 kg (control…2020 American Transplant Congress
The Therapeutic Potential of Human Liver-Derived Stem Cells Transplantation in Carbon Tetrachloride-Induced Rat Liver Cirrhotic Model
*Purpose: Cirrhosis is a long-term consequence of chronic hepatic injury and there are no effective treatment methods. Mesenchymal stem cells (MSCs) have been reported to…2020 American Transplant Congress
Epithelial To Mesenchymal Transition Mediates Engraftment Of Endoderm And Hepatic Progenitor Cells In The Quiescent Liver
*Purpose: Stem cell transplantation to the liver is a promising therapeutic strategy for a variety of disorders. Hepatocyte transplantation has short term efficacy, but can…2020 American Transplant Congress
Improved Survival of Acute Liver Failure by “Off-the-Shelf” Bioartificial Liver Support System Using Immobilized Cryopreserved Hepatocyte Spheroids in Porcine Model
*Purpose: Acute liver failure (ALF) has a rapid and unpredictable onset with high mortality. The only current treatment is to transplant a donor organ but…2020 American Transplant Congress
Identification of Novel Gene Targets Inducing Resistance in Liver Ischemia Reperfusion Injury by CRISPR Screening
*Purpose: Liver transplantation (LT) is the best treatment option for patients with end-stage liver disease (ESLD). However, the gap between available donors and recipients in…
