    Abstract

    Modular Immune-Homeostatic Microparticles Promote Immune Tolerance in Mouse Autoimmune Models

    The authors developed immune-homeostatic microparticles that treat multiple mouse models of autoimmunity via induction of apoptosis in activated T cells and reestablishment of regulatory T cells.
    [Science Translational Medicine]

    Abstract

    TGFβ Restricts Expansion, Survival, and Function of T Cells within the Tuberculous Granuloma

    In a murine infection model, scientists observed that IFNÉ£ production by Mycobacterium tuberculosis-specific CD4 T cells was rapidly extinguished within the granuloma but not within unaffected lung regions, suggesting localized immunosuppression.

    AbstractGraphical Abstract

    Oxidative Phosphorylation Enhances the Leukemogenic Capacity and Resistance to Chemotherapy of B Cell Acute Lymphoblastic Leukemia

    B cell acute lymphoblastic leukemia (B-ALL) cells with a low SoNar ratio had enhanced mitochondrial respiration capacity, mainly resided in the vascular niche, and were enriched with more functional leukemia-initiating cells than that of SoNar-high cells in a murine B-ALL model.

    Cytotoxic CD8+ T Cells Promote Granzyme B-Dependent Adverse Post-ischemic Cardiac Remodeling

    The authors showed that following acute myocardial infarction in mice, CD8+ T lymphocytes were recruited and activated in the ischemic heart tissue and release Granzyme B, leading to cardiomyocyte apoptosis, adverse ventricular remodeling and deterioration of myocardial function.

    Endogenous Modification of the Chemoattractant CXCL5 Alters Receptor Usage and Enhances Its Activity toward Neutrophils and Monocytes

    The authors chemically synthesized native CXCL5, truncated CXCL5, and the citrullinated versions and characterized their functions in vitro and in vivo.
    [Science Signaling]

    Abstract

    The Cytosolic DNA Sensor cGAS Recognizes Neutrophil Extracellular Traps

    Researchers showed that neutrophil extracellular trap (NET) induction in mice treated with the lectin concanavalin A, a model of autoimmune hepatitis, resulted in cGAS-dependent stimulation of an IFN response, suggesting that NETs activated cGAS in vivopan>]

    Abstract

    Programmed Death-1 Promotes Contused Skeletal Muscle Regeneration by Regulating Treg Cells and Macrophages

    Investigators explored the role of programmed death-1 in contused skeletal muscle regeneration, and to clarify the regulation of programmed death-1 on Treg cell generation and macrophage polarization
