    Tsc2 disruption in mesenchymal progenitors results in tumors with vascular anomalies overexpressing Lgals3

    Peter J Klover, Rajesh L Thangapazham ... Thomas N Darling
    Tsc2 inactivation in mouse mesenchymal progenitors produced tumors with vascular anomalies reminiscent of human angiomyolipomas, and a gene expression signature in Tsc2-deficient tissues which included Lgals3, as a novel potential biomarker for TSC1/2 loss.

    The mammalian lectin galectin-8 induces RANKL expression, osteoclastogenesis, and bone mass reduction in mice

    Yaron Vinik, Hadas Shatz-Azoulay ... Yehiel Zick
    The secreted sugar-binding protein galectin-8 causes osteoblasts to secrete factors that promote the differentiation of bone marrow cells into osteoclasts; targeting this protein could therefore potentially help treat diseases associated with excessive bone loss.

    Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

    Haik Mkhikian, Christie-Lynn Mortales ... Michael Demetriou
    Structurally dissimilar N-glycans can be functionally equivalent, and are produced via a self-correcting feature of the Golgi.

    Cell-autonomous targeting of arabinogalactan by host immune factors inhibits mycobacterial growth

    Lianhua Qin, Junfang Xu ... Haipeng Liu
    Galectin-9 directly binds to arabinogalactan (AG), leading to the identification of AG-specific monoclonal antibodies that effectively inhibit Mycobacterium tuberculosis growth, providing insights for novel tuberculosis therapies.

    Glycolysis and glutaminolysis cooperatively control T cell function by limiting metabolite supply to N-glycosylation

    Lindsey Araujo, Phillip Khim ... Michael Demetriou
    Metabolic switches between oxidative phosphorylation and aerobic glycolysis plus glutaminolysis direct T cell function by altering the flux of glucose and glutamine to N-glycosylation.

    Galectin-9 regulates the threshold of B cell activation and autoimmunity

    Logan K Smith, Kareem Fawaz, Bebhinn Treanor
    Galectin-9-deficient mice develop spontaneous autoimmunity, driven by a decreased threshold of B cell activation and enhanced auto-antigen delivery to the spleen by increased B1a-derived autoantibodies.

    Time-dependent cytokine and chemokine changes in mouse cerebral cortex following a mild traumatic brain injury

    David Tweedie, Hanuma Kumar Karnati ... Nigel H Greig
    Protein changes in cerebral cortex following a mild traumatic brain injury (mTBI) identified herein will help in the development of monitoring and response biomarkers that may translate to clinical mTBI.

    Ym1 protein crystals promote type 2 immunity

    Ines Heyndrickx, Kim Deswarte ... Bart N Lambrecht
    Protein crystallization is a rare event yet Ym1 crystals made from a chitinase-like protein are abundantly found in eosinophilic airway inflammation, where they promote type 2 immunity.

    The role of P2Y12 in the kinetics of microglial self-renewal and maturation in the adult visual cortex in vivo

    Monique S Mendes, Linh Le ... Ania K Majewska
    Adult microglia are born by the division of single surviving microglia that rapidly acquire mature morphologies and functions in order to perform their physiological roles in the brain.

    Guanylate binding proteins directly attack Toxoplasma gondii via supramolecular complexes

    Elisabeth Kravets, Daniel Degrandi ... Klaus Pfeffer
    Cellular immunity against Toxoplasma parasites is orchestrated by GBP complexes attacking the parasite membrane.
