    Traf3 Inactivation Promotes the Development of Intrahepatic Cholangiocarcinoma via NIK-Mediated Hepatocyte Transdifferentiation

    Scientists performed a Sleeping Beauty transposon-based in vivo insertional mutagenesis screen in liver-specific Pten-deficient mice and identified tumor necrosis factor receptor-related factor 3 (Traf3) as the most significantly mutated gene in murine intrahepatic cholangiocarcinomas in a loss-of-function manner.

    Immune Profiling of Combined Hepatocellular-Cholangiocarcinoma Reveals Distinct Subtypes and Activation of Gene Signatures Predictive of Response to Immunotherapy

    The authors identified a subgroup of combined hepatocellular (HCC)-cholangiocarcinoma that displayed features of an ongoing intratumor immune response, along with an activation of gene signatures predictive of response to immunotherapy in HCC.

    Abstract

    Plasmolipin Regulates Basolateral-to-Apical Transcytosis of ICAM-1 and Leukocyte Adhesion in Polarized Hepatic Epithelial Cells

    Researchers investigated the molecular mechanisms that determined intercellular adhesion receptor (ICAM)-1 localization into apical membrane domains of polarized hepatic epithelial cells, and their effect on lymphocyte-hepatic epithelial cell interaction.

    Abstract

    Sapidolide a Alleviates Acetaminophen-Induced Acute Liver Injury by Inhibiting NLRP3 Inflammasome Activation in Macrophages

    The authors investigated whether sapidolide A exerted protective effects on macrophages, thus alleviating the secondary hepatocyte damage in an acetaminophen-induced liver injury.

    Abstract

    Tetramethylpyrazine Prevents Liver Fibrotic Injury in Mice by Targeting Hepatocyte-Derived and Mitochondrial DNA-Enriched Extracellular Vesicles

    Researchers investigated whether tetramethylpyrazine exerted liver-protective action through regulating extracellular vesicle-dependent intercellular communication between hepatocytes and hepatic stellate cells.

    Abstract

    MAPK p38/Ulk1 Pathway Inhibits Autophagy and Induces IL-1β Expression in Hepatic Stellate Cells

    Investigators revealed a continuous signaling pathway, MAPK p38-Ulk1 phosphorylation-Ulk1/Atg13 disruption, which inhibited autophagy and induced IL-1β expression in hepatic stellate cells.
