    Mechanisms of CD40-Dependent cDC1 Licensing beyond Costimulation

    Scientists identified CD40-induced genes in classical type 1 dendritic cells, including Cd70, Tnfsf9, Ptgs2 and Bcl2l1, and examined their contributions to anti-tumor immunity.

    Abstract

    SUSD2 Suppresses CD8+ T Cell Antitumor Immunity by Targeting IL-2 Receptor Signaling

    Susd2−/− effector CD8+ T cells showed enhanced production of antitumor molecules, which consequently blunted tumor growth in multiple syngeneic mouse tumor models.

    Abstract

    Antitumor Immunity Induced by Antibody-Based Natural Killer Cell Engager Therapeutics Armed with Not-Alpha IL-2 Variant

    The authors reported the design of tetraspecific molecules engaging natural killer cell-activating receptors NKp46 and CD16a, the β-chain of the interleukin-2 receptor, and a tumor-associated antigen.

    Clonal IgA and IgG Autoantibodies from Individuals at Risk for Rheumatoid Arthritis Identify an Arthritogenic Strain of Subdoligranulum

    Investigators identified cross-reactivity between rheumatoid arthritis-relevant autoantigens and bacterial taxa in the closely related families Lachnospiraceae and Ruminococcaceae.

    Abstract

    Therapeutic Gene Editing of T Cells to Correct CTLA-4 Insufficiency

    Scientists designed a homology-directed repair gene editing strategy that inserted the CTLA-4 cDNA into the first intron of the CTLA-4 genomic locus in primary human T cells.

    Abstract

    Penetrating Macrophage-Based Nanoformulation for Periodontitis Treatment

    Investigators prepared a penetrating macrophage-based nanoformulation-encapsulating hydrogel that responded to the periodontitis microenvironment.

    The ZFP36 Family of RNA Binding Proteins Regulates Homeostatic and Autoreactive T Cell Responses

    The authors found a redundant and critical role for the zinc finger protein 36 (ZFP36) proteins in regulating T cell quiescence.

    Abstract

    A Circulating Subset of iNKT Cells Mediates Antitumor and Antiviral Immunity

    Invariant natural killer T (iNKT) cells in the thymus were divided into three subpopulations by the expression of the natural killer cell receptor CD244 and the chemokine receptor CXCR6 and designated as C0, C1, or C2 iNKT cells.

    VISTA Targeting of T-cell Quiescence and Myeloid Suppression Overcomes Adaptive Resistance

    Mechanisms of enhanced anti-tumor immunity were investigated using scRNA-seq, multiplex image analysis and flow cytometry of the tumor immune infiltrate. In both treatment models, anti-VISTA upregulated stimulated antigen-presentation pathways and reduced myeloid mediated suppression.

    Abstract

    Integrative Analysis Links Ferroptosis to Necrotizing Enterocolitis and Reveals the Role of ACSL4 in Immune Disorders

    Ferroptosis was identified to play a role in necrotizing enterocolitis (NEC) using bioinformatics analyses and wet experiments. Inhibition of ferroptosis significantly alleviated NEC in newborn mice.
