    LACC1 Bridges NOS2 and Polyamine Metabolism in Inflammatory Macrophages

    Scientists elucidated a shared biochemical function of laccase domain-containing 1 (LACC1) in mice and humans, converting L-citrulline to L-ornithine and isocyanic acid and serving as a bridge between proinflammatory nitric oxide synthase (NOS2) and polyamine immunometabolism.

    Abstract

    Differences in CD80 and CD86 Transendocytosis Reveal CD86 as a Key Target for CTLA-4 Immune Regulation

    Scientists demonstrated that, although CTLA-4 targeted both CD80 and CD86 for destruction via transendocytosis, this process resulted in separate fates for CTLA-4 itself.

    Abstract

    PDIA3 Epitope-Driven Immune Autoreactivity Contributes to Hepatic Damage in Type 2 Diabetes

    Researchers indicated that metabolic insults caused by a high-fat and high-fructose diet elicited liver damage and promoted pathogenic immune autoreactivity driven by T and B cell protein disulfide isomerase family A member 3 (PDIA3) epitopes.

    Abstract

    Transcription-Independent Regulation of STING Activation and Innate Immune Responses by IRF8 in Monocytes

    Investigators showed that interferon regulatory factor 8 (IRF8) was essential for efficient activation of STING-mediated innate immune responses in monocytes.

    Altered Sialidase Expression in Human Myeloid Cells Undergoing Apoptosis and Differentiation

    The authors studied neuraminidase activity and expression in mature human neutrophils (PMNs) and the HL60 promyelocytic leukemic cell line, and changes that might have occurred in PMNs undergoing apoptosis and HL60 cells during their differentiation into PMN-like cells.
