    Macrophage-Derived 25-Hydroxycholesterol Promotes Vascular Inflammation, Atherogenesis, and Lesion Remodeling

    The effect of cholesterol 25-hydroxylase on atherosclerosis progression was analyzed by bone marrow adoptive transfer of cells from wild-type or Ch25h–/– mice to lethally irradiated Ldlr–/– mice, followed by a Western diet feeding for 12 weeks.

    Circulating c-Met–Expressing Memory T Cells Define Cardiac Autoimmunity

    In-depth phenotyping of peripheral blood T cells, including c-Met+ T cells, was undertaken in groups of patients with inflammatory and noninflammatory cardiomyopathies, patients with noncardiac autoimmunity, and healthy controls.

    Abstract

    Eosinophils Protect against Pulmonary Hypertension through 14-HDHA and 17-HDHA

    Eosinophils infiltration and chemotaxis were investigated in peripheral blood and lung tissues from pulmonary arterial hypertension patients without allergic history and sugen/hypoxia-induced pulmonary hypertension mice.

    Abstract

    Plasma Cell but Not CD20-Mediated B Cell Depletion Protects from Bleomycin-Induced Lung Fibrosis

    To determine the therapeutic potential of inhibiting B cell function in pulmonary fibrosis, scientists examined the effects of anti-CD20 B cell ablation therapy to selectively remove mature B cells from the immune system and inhibit bleomycin-induced lung fibrosis.

    Abstract

    CTLA-4 on Thymic Epithelial Cells Complements Aire for T Cell Central Tolerance

    Researchers found that a small population of medullary thymic epithelial cells expressed the coinhibitory receptor cytotoxic T lymphocyte-associated protein 4 (CTLA-4) . These CTLA-4+ cells were detectable in perinates, peaked around young adulthood and expanded sixfold in the absence of Aire.

    Abstract

    Gestationally Dependent Immune Organization at the Maternal-Fetal Interface

    Scientists developed a single-cell framework to simultaneously immuno-phenotype circulating, endovascular, and tissue-resident cells at the maternal-fetal interface throughout gestation, discriminating maternal and fetal contributions.

    Intravenous Mesenchymal Stem Cell Administration Modulates Monocytes/Macrophages and Ameliorates Asthmatic Airway Inflammation in a Murine Asthma Model

    Investigators determined the effect of human umbilical cord-derived mesenchymal stem cells on asthmatic lungs by modulating innate immune cells and effector T cells using a murine asthmatic model.

    ZDHHC9 Promotes Colon Tumor Growth by Inhibiting Effector T Cells

    Using Gene Expression Profiling Interactive Analysis and Tumor Immune Estimation Resource, data obtained from The Cancer Genome Atlas were analyzed, and the results showed that ZDHHC9 was highly expressed in colon cancer and that patients with higher ZDHHC9 expression levels had a worse prognosis.
