    Induced Phase Separation of Mutant NF2 Imprisons the cGAS-STING Machinery to Abrogate Antitumor Immunity

    Researchers found that Neurofibromin 2 (NF2) facilitated innate immunity by regulating YAP/TAZ-mediated TBK1 inhibition. Patient-derived individual mutations in the FERM domain of NF2 converted NF2 into a potent suppressor of cGAS-STING signaling.

    Myeloid Cell-Based Delivery of IFN-γ Reprograms the Leukemia Microenvironment and Induces Anti-Tumoral Immune Responses

    The authors employed gene transfer into hematopoietic stem and progenitor cells to selectively express anti-tumoral cytokines in tumor-infiltrating monocytes/macrophages.

    Simultaneous Engagement of Tumor and Stroma Targeting Antibodies by Engineered NK-92 Cells Expressing CD64 Controls Prostate Cancer Growth

    Investigators engineered a NK cell line to express CD64, the sole human high-affinity IgG Fcγ receptor, and bound these cells with antibodies to provide interchangeable tumor-targeting elements.

    Gain-of-Function p53R172H Mutation Drives Accumulation of Neutrophils in Pancreatic Tumors, Promoting Resistance to Immunotherapy

    Researchers compared the immune profiles generated by KrasG12D-mutated mouse pancreatic ductal epithelial cells engineered genetically to express the Trp53R172H mutation with their p53 wild-type control.

    The Composition of the Gut Microbiota Following Early-Life Antibiotic Exposure Affects Host Health and Longevity in Later Life

    Scientists investigated the effect of early-life antibiotic exposure on otherwise healthy, normal chow-fed, wild-type mice, monitoring these mice for more than 700 days in comparison with untreated control mice.

    Tissue Environment, Not Ontogeny, Defines Murine Intestinal Intraepithelial T Lymphocytes

    To gain functional insights into tissue-resident intestinal intraepithelial T lymphocytes (T-IEL), the authors used high-resolution, quantitative mass spectrometry to compare the proteomes of induced T-IEL and natural T-IEL subsets, with naive CD8+ T cells from lymph nodes.

    Expansion of Monocytic Myeloid-Derived Suppressor Cells Ameliorated Intestinal Inflammatory Response by Radiation through SOCS3 Expression

    Scientists demonstrated that radiation exposure in mice promoted the expansion of splenic and intestinal myeloid-derived suppressor cells and caused intestinal inflammation due to the increased secretion of cytokines.

    Immune Normalization Strategy against Suboptimal Health Status: Safe and Efficacious Therapy Using Mixed-Natural Killer Cells

    Researchers established in vitro cultured mixed-natural killer cells (NKM) to achieve immune normalization. The in vitro cytotoxicity of NKM cells was tenfold higher than that of peripheral blood mononuclear cells

    Antagonism of Inhibitors of Apoptosis Proteins Reveals a Novel, Immune-Based Therapeutic Approach for T-Cell Lymphoma

    Researchers showed that tolinapant acted as an efficacious immunomodulatory molecule capable of inducing complete tumor regression in a syngeneic model of T cell lymphoma exclusively in the presence of an intact immune system.

    Glutamine Metabolism Regulates Endothelial to Hematopoietic Transition and Hematopoietic Lineage Specification

    Scientists showed that glutamine was a crucial regulator of endothelial to hematopoietic transition and a rate limiting metabolite in the hematopoietic differentiation of hemogenic endothelial cells.

    Abstract

    Cutting Both Ways: The Innate Immune Response to Oncolytic Virotherapy

    The authors discuss the importance of oncolytic viruses-based combination therapies in optimizing antiviral and antitumor innate immune responses stimulated by virotherapy toward tumor eradication, and how these processes vary depending on the tumor and oncolytic viruses in question.
