    TOP STORY

    Essential Role of a ThPOK Autoregulatory Loop in the Maintenance of Mature CD4+ T Cell Identity and Function

    The authors described a new autoregulatory loop whereby ThPOK bound to the SilThPOK to maintain its own long-term expression in CD4 T cells.

    Peripheral B-Cells Repress B-Cell Regeneration in Aging through a TNFα/IGFBP-1/IGF1 Immune-Endocrine Axis

    Researchers uncovered an immune-endocrine regulatory circuit that mediated cross-talk between peripheral B-cells and progenitors in the bone marrow, to balance B-lymphopoiesis in both human and mouse aging.

    Abstract

    Pax5 Regulates B Cell Immunity by Promoting PI3K Signaling via PTEN Down-Regulation

    Scientists demonstrated that the loss of Pax5 by conditional mutagenesis in peripheral B lymphocytes led to the strong reduction of B-1a, marginal zone and germinal center B cells as well as plasma cells.

    Abstract

    Mitochondrial Transcription Factor A in RORγt+ Lymphocytes Regulate Small Intestine Homeostasis and Metabolism

    Conditional deletion of mitochondrial transcription factor A in RORγt+ lymphocytes significantly affected systemic γδT17 cell maintenance and reduced group t3 innate lymphoid cells without affecting T helper 17 cells in the gut.

    STING Suppresses Bone Cancer Pain via Immune and Neuronal Modulation

    Investigators reported that agonists of the immune regulator stimulator of interferon genes (STING) confered remarkable protection against cancer pain, bone destruction, and local tumor burden.
    [Nature Communications]

    Abstract

    Anti-Tumor Immunity in Mismatch Repair-Deficient Colorectal Cancers Requires Type I IFN–Driven CCL5 and CXCL10

    The authors discovered that selective recruitment and activation of systemic CD8+ T cells into DNA mismatch repair colorectal cancers strictly depended on overexpression of CCL5 and CXCL10 due to endogenous activation of cGAS/STING and type I IFN signaling by damaged DNA.

    Abstract

    LRRK2 Is Required for CD38-Mediated NAADP-Ca2+ Signaling and the Downstream Activation of TFEB (Transcription Factor EB) in Immune Cells

    Researchers mechanistically and functionally linked CD38 and (leucine-rich repeat kinase 2) LRRK2 as upstream activators of transcription factor EB (TFEB), a host defense transcription factor and the master transcriptional regulator of the autophagy/lysosome machinery.

    Abstract

    Neuroblastoma Formation Requires Unconventional CD4 T Cells and Arginase-1-Dependent Myeloid Cells

    To understand the different facets of immune-tumor collaboration through genetics, spatial transcriptomics, and immunological manipulation with non-invasive, longitudinal imaging, the authors generated a penetrant double oncogene-driven autochthonous model of neuroblastoma.

    Abstract

    Macrophage-Derived Cholesterol Contributes to Therapeutic Resistance in Prostate Cancer

    In a syngeneic model that reflected the mutational landscape of castrate-resistant prostate cancer, macrophage depletion resulted in a reduced transcriptional signature for steroid and bile acid synthesis, indicating potential perturbation of cholesterol metabolism.

    Abstract

    Treg-Expressed CTLA-4 Depletes CD80/CD86 by Trogocytosis, Releasing Free PD-L1 on Antigen-Presenting Cells

    Investigators showed that Treg-expressed CTLA-4 facilitated Treg-antigen-presenting cells conjugation and immune synapse formation.

    Abstract

    Hijacking TYRO3 from Tumor Cells via Trogocytosis Enhances NK-Cell Effector Functions and Proliferation

    Researchers found that although NK cells did not express endogenous TYRO3 on the cell surface, activated NK cells rapidly acquired TYRO3 from tumor cells via trogocytosis in vitro and in vivo.

    Abstract

    Effector Memory CD4+T Cells in Mesenteric Lymph Nodes Mediate Bone Loss in Food-Allergic Enteropathy Model Mice, Creating IL-4 Dominance

    The authors investigated a non-IgE-mediated food-allergic enteropathy model of ovalbumin (OVA) 23-3 mice expressing OVA-specific T-cell-receptor transgenes.
    [Mucosal Immunology]

    Abstract

    Butyrophilin-Like 2 Regulates Site-Specific Adaptations of Intestinal γδ Intraepithelial Lymphocytes

    Scientists showed that butyrophilin-like suppressed homeostatic proliferation of γδ intraepithelial lymphocytes preferentially in the ileum.

    Modulation of Preeclampsia by the Cholinergic Anti-inflammatory Pathway: Therapeutic Perspectives

    Investigators summarize reports in the literature regarding the roles of peripheral and reflex cholinergic neuroinflammatory pathways of nicotinic acetylcholine receptors in reprogramming preeclampsia complications in mothers and their progenies.

    The Role of Interleukin-1β in the Immune Response to Contact Allergens

    The authors summarize the current literature regarding the basic immunological mechanisms mediated by IL-1β in the different phases of allergic contact dermatitis (ACD) and highlights potential IL-1β-targeted treatment options, which in the future may be relevant in the treatment of patients with ACD.
