    Novel Antigen Presenting Cell Imparts Treg-Dependent Tolerance to Gut Microbiota

    The authors identified a new class of RORγt+ antigen-presenting cells, dubbed Thetis cells, with transcriptional features of both medullary thymic epithelial cells and dendritic cells, comprising four major sub-groups.

    Induction of a Colitogenic Phenotype in Th1-Like Cells Depends on Interleukin-23 Receptor Signaling

    Using IL-23R-deficient Th1-like cells, scientists demonstrated that IL-23R was required for the development of a highly colitogenic phenotype.

    Neuropilin-1 (NRP1) Expression Distinguishes Self-Reactive Helper T Cells in Systemic Autoimmune Disease

    NRP1+ T helper cells, absent in non-regulatory T cell subsets in normal mice, appeared in models of systemic autoimmune disease and strongly correlated with systemic autoimmune disease symptoms.

    BCG-Induced Tumor Immunity Requires Tumor-Intrinsic CIITA Independent of MHC-II

    Researchers demonstrated that the IFNγ-driven, tumor cell intrinsic expression of the class II transactivator CIITA was required for activation of a tumor-specific CD4 T-cell response and BCG-induced tumor immunity.

    Abstract

    Glucose Promotes Regulatory T Cell Differentiation to Maintain Intestinal Homeostasis

    The authors showed that while glucose at a high concentration promoted intestinal inflammation, it suppressed colitis at a moderate dose, which increased the proportion of intestinal Treg cells but did not affect effector CD4+ T cells.

    Yin and Yang of Cannabinoid CB1 receptor: CB1 Deletion in Immune Cells Causes Exacerbation while CB1 Deletion in Non-Immune Cells Attenuates Obesity

    Chimeras with cannabinoid receptor 1 (CB1)-/- in immune cells showed exacerbation in diet-induced obesity combined with infiltration of bone-marrow derived macrophages to the brain and visceral adipose tissue, elevated food intake, and increased glucose intolerance.

    Changes of Macrophage and CD4+ T Cell in Inflammatory Response in Type 1 Diabetic Mice

    The intraperitoneal injection of streptozocin was used to induce a type 1 diabetes mellitus mouse model; the blood glucose, body weight, and the expression of inflammatory factors in the kidney were measured.
