    Lymph Node Colonization Induces Tumor-Immune Tolerance to Promote Distant Metastasis

    Lymph node metastases resisted T cell-mediated cytotoxicity, induced antigen-specific regulatory T cells, and generated tumor-specific immune tolerance that subsequently facilitated distant tumor colonization.

    Mesothelial Cell-Derived Antigen-Presenting Cancer-Associated Fibroblasts Induce Expansion of Regulatory T Cells in Pancreatic Cancer

    The authors showed that antigen-presenting cancer-associated fibroblasts directly ligated and induced naive CD4+ T cells into regulatory T cells in an antigen-specific manner.

    Antigen-Bearing Outer Membrane Vesicles as Tumor Vaccines Produced In Situ by Ingested Genetically Engineered Bacteria

    Researchers showed that outer membrane vesicles fused to a tumor antigen and produced in the intestine by ingested genetically engineered bacteria function as effective tumor vaccines in mice.

    Abstract

    Albumin Nanoparticle Containing a PI3Kγ Inhibitor and Paclitaxel in Combination with α-PD1 Induces Tumor Remission of Breast Cancer in Mice

    Investigators designed an albumin nanoparticle, Nano-PI, containing the immunomodulators PI3Kγ inhibitor and paclitaxell and treated two breast cancer mouse models with Nano-PI in combination with α-PD1, which remodeled the tumor microenvironment in both lymph nodes and tumors.

    Chronic Inflammatory Arthritis Drives Systemic Changes in Circadian Energy Metabolism

    Using an established mouse model of rheumatoid arthritis, scientists showed that chronic inflammatory arthritis resulted in rhythmic joint inflammation and drove major changes in muscle and liver energy metabolism and rhythmic gene expression.

    Antibody-Mediated Blockade of the IL23 Receptor Destabilizes Intratumoral Regulatory T Cells and Enhances Immunotherapy

    Researchers provided evidence that the interleukin 23 (IL23) receptor expressed by tumor-infiltrating regulatory T cells promoted suppressive activity.

    Abstract

    The Neuropeptide VIP Potentiates Intestinal Innate Type 2 and Type 3 Immunity in Response to Feeding

    Investigators showed that vasoactive intestinal peptide (VIP), produced by the nervous system in response to feeding, potentiated the production of effector cytokines by intestinal type 2 and type 3 innate lymphoid cells.

    Abstract

    Spatial Analysis and CD25-Expression Identify Regulatory T Cells as Predictors of a Poor Prognosis in Colorectal Cancer

    Scientists investigated the prognostic heterogeneity of regulatory T cells in colorectal cancer (CRC) by co-expression patterns and spatial analyses with diverse T cell markers, using multiplex fluorescence immunohistochemistry and digital image analysis in two consecutive series of primary CRCs.

    Abstract

    Psoriatic Arthritis from a Mechanistic Perspective

    Scientists discuss the contribution of mechanical factors triggering an exaggerated inflammatory response, the impact of adipose tissue and altered lipid metabolism and the influence of intestinal dysbiosis in the psoriatic arthritis disease process.

    Abstract

    Spatial Determinants of CD8+ T Cell Differentiation in Cancer

    The authors discuss the cellular, as well as the soluble and surface-bound signals that regulate CD8+ T cell phenotypes and functions in a topologically-regulated manner, highlighting where new spatial transcriptomics and imaging technologies can uncover mechanistic insights.
