    Modulation of Gut Barrier Functions in Ulcerative Colitis by Hyaluronic Acid System

    A biphasic hyaluronan (HA) enema suspension, naïve-HA system that protected the dysregulated gut epithelium by decreasing the inflammation, permeability, and helping in maintaining the epithelial barrier integrity in the dextran sodium sulfate-induced colitis mice model was reported.

    The Protein Kinase Activity of NME7 Activates Wnt/β-Catenin Signaling to Promote One-Carbon Metabolism in Hepatocellular Carcinoma

    High-throughput RNA-seq was used to identify the differentially expressed circular RNAs upon IL-6 stimulation in intrahepatic cholangiocarcinoma cells.
    [Hepatology]

    Abstract

    Highly Immunogenic Cancer Cells Require Activation of the WNT Pathway for Immunological Escape

    Scientists showed that activation of the WNT/β-catenin signaling pathway contributed to the development of a noninflamed tumor microenvironment in tumors with high tumor mutation burden.

    Abstract

    Single-Cell Multiomics Defines Tolerogenic Extrathymic Aire-Expressing Populations with Unique Homology to Thymic Epithelium

    Researchers used single-cell multiomics, transgenic murine models, and functional approaches to define extrathymic Aire-expressing cells at the transcriptional, genomic, and proteomic level.
    [Science Immunology]

    Abstract

    Cancer-Associated MSC Drive Tumor Immune Exclusion and Resistance to Immunotherapy, Which Can Be Overcome by Hedgehog Inhibition

    Using an immune “hot” mouse ovarian cancer model, scientists found that cancer-associated-MSCs drove CD8+ T cell tumor immune exclusion and reduced response to anti–PD-L1 immune checkpoint inhibitor via secretion of numerous chemokines.

    FGFR3 Destabilizes PD-L1 Via NEDD4 to Control T Cell-Mediated Bladder Cancer Immune Surveillance

    The authors demonstrated that inhibition of fibroblast growth factor receptor 3 (FGFR3) in FGFR3-activated bladder cancer elevated PD-L1 protein levels by affecting its ubiquitination, thereby inhibiting the anti-tumor activity of CD8+ T cells.
    [Cancer Research]

    Abstract

    Desmosterol Suppresses Macrophage Inflammasome Activation and Protects against Vascular Inflammation and Atherosclerosis

    Researchers reported that desmosterol, the most abundant cholesterol biosynthetic intermediate in human coronary artery lesions, played an essential role during atherogenesis, serving as a key molecule integrating cholesterol homeostasis and immune responses in macrophages.
    [Proceedings of the National Academy of Sciences of the United States of America]

    Abstract

    MicroRNA-29 Specifies Age-Related Differences in the CD8+ T Cell Immune Response

    Scientists examined the role of miR-29 in neonatal and adult CD8+ T cells, which expressed different amounts of miR-29 only prior to infection and adopt profoundly different fates after immune challenge.
    [Cell Reports]

    Abstract

    Dynamic Variability in SHP-1 Abundance Determines Natural Killer Cell Responsiveness

    Human and mouse NK cell populations with high responsiveness had low Src homology 2 domain–containing phosphatase-1 (SHP-1) abundance, and a reduction in SHP-1 abundance in NK cells enhanced their responsiveness.
    [Science Signaling]

    Abstract

    Development of Allogeneic HSC-Engineered iNKT Cells for Off-the-Shelf Cancer Immunotherapy

    By combining hematopoietic stem cell (HSC) gene engineering and in vitro differentiation, scientists generated human allogeneic HSC-engineered invariant natural killer T cells at high yield and purity.
