    Glioblastomas Acquire Myeloid-Affiliated Transcriptional Programs via Epigenetic Immunoediting to Elicit Immune Evasion

    By serially transplanting glioblastoma multiforme stem cells (GSCs) into immunocompetent hosts, scientists uncovered an acquired capability of GSCs to escape immune clearance by establishing an enhanced immunosuppressive tumor microenvironment.

    Interleukin-17D Regulates Group 3 Innate Lymphoid Cell Function through Its Receptor CD93

    Researchers examined the role of interleukin (IL)-17D, a poorly understood member in the IL-17 family. Il17d−/− mice were more susceptible to acute colitis, bacterial infection and experimentally induced colon cancer than their wildtype counterparts.

    Deconvoluting Global Cytokine Signaling Networks in Natural Killer Cells

    The authors employed a multi-omics approach to deconstruct and rebuild the complex interaction of multiple cytokine signaling pathways in natural killer cells.

    Abstract

    Rescue of Maternal Immune Activation-Induced Behavioral Abnormalities in Adult Mouse Offspring by Pathogen-Activated Maternal Treg Cells

    Scientists showed that adoptive transfer of Treg cells largely reversed maternal immune activation-induced phenotypes.

    Abstract

    Therapeutic B-Cell Depletion Reverses Progression of Alzheimer’s Disease

    Using three different murine transgenic models, investigators provide counterintuitive evidence that the Alzheimer’s disease progression required B cells.

    TIM4 Expression by Dendritic Cells Mediates Uptake of Tumor-Associated Antigens and Anti-Tumor Responses

    The authors showed that capture and engulfment of cell associated antigens by tissue resident lung type 1 dendritic cells was inhibited during progression of mouse lung tumors.

    Ssu72 Is a T-cell Receptor-Responsive Modifier That Is Indispensable for Regulatory T Cells

    Scientists found that the Ssu72 phosphatase was activated by various T-cell receptor signaling pathways, including the T-cell receptor and IL-2R pathways, and localized at the cell membrane.

    Abstract

    CD169+ Lymph Node Macrophages Have Protective Functions in Mouse Breast Cancer Metastasis

    Researchers found CD169+ macrophages as the predominant macrophage subtype in naive lymph nodes, which underwent proliferative expansion in response to tumor stimuli.

    UTX Promotes CD8+ T Cell-Mediated Antiviral Defenses but Reduces T Cell Durability

    Investigators showed that T cell receptor-stimulated CD8+ T cells increased their expression of ubiquitously transcribed tetratricopeptide repeat, X chromosome (UTX) to enhance gene expression.

    Nicotinamide Riboside, an NAD+ Precursor, Attenuates Inflammation and Oxidative Stress by Activating Sirtuin 1 in Alcohol-Stimulated Macrophages

    Researchers investigated the effects of nicotinamide riboside, a natural nicotinamide adenine dinucleotide precursor, on alcohol-induced inflammation and oxidative stress in macrophages.

    Abstract

    The IRENA lncRNA Converts Chemotherapy-Polarized Tumor-Suppressing Macrophages to Tumor-Promoting Phenotypes in Breast Cancer

    Scientists found that IFN-activated proinflammatory macrophages after neoadjuvant chemotherapy enhanced antitumor immunity but promoted cancer chemoresistance.
    [Nature Cancer]

    Abstract

    Accumulation of Cytotoxic T Cells in the Aged CNS Leads to Axon Degeneration and Contributes to Cognitive and Motor Decline

    Investigators examined the role of cytotoxic CD8+ T lymphocytes, a type of adaptive immune cells previously identified as amplifiers of axonal perturbation in various models of genetically mediated central nervous system (CNS) diseases.

    Abstract

    Does the Epithelial Barrier Hypothesis Explain the Increase in Allergy, Autoimmunity and Other Chronic Conditions?

    Scientists discuss how the immune responses to dysbiotic microbiota that cross the damaged barrier may be involved in the development of allergic and autoimmune diseases.
    [Nature Reviews Immunology]

    Abstract

    Chemokines and the Immune Response to Cancer

    The authors review the role of the chemokine system in anti-tumor and pro-tumor immune responses and discuss how malignant cells and the tumor microenvironment regulate the overall chemokine landscape to shape the type and outcome of immune responses to cancer and cancer treatment.
