    Inflammatory stress signaling via NF-kB alters accessible cholesterol to upregulate SREBP2 transcriptional activity in endothelial cells

    Joseph Wayne M Fowler, Rong Zhang ... William C Sessa
    Detailed biochemical and metabolic analysis of the inflammatory response in human endothelial cells reveals that inflammation directly regulates cholesterol homeostasis.

    Wnt signaling mediates acquisition of blood–brain barrier properties in naïve endothelium derived from human pluripotent stem cells

    Benjamin D Gastfriend, Hideaki Nishihara ... Eric V Shusta
    Activation of Wnt/β-catenin signaling in endothelial progenitors derived from human pluripotent stem cells partially induces the specialized blood–brain barrier phenotype while the same treatment in matured endothelial cells is less efficacious.

    Gut microbiota induces high platelet response in patients with ST segment elevation myocardial infarction after ticagrelor treatment

    Xi Zhang, Xiaolin Zhang ... Yaling Han
    After myocardial infarction, gut microbiota affects platelet aggregation rate by regulating the absorption and metabolism of ticagrelor.

    Nuclear receptor corepressor 1 controls regulatory T cell subset differentiation and effector function

    Valentina Stolz, Rafael de Freitas e Silva ... Wilfried Ellmeier
    The transcriptional adapter protein NCOR1 that links chromatin-modifying enzymes with gene-specific transcription factors controls naive and effector regulatory T cell states.

    Molecular structures of the eukaryotic retinal importer ABCA4

    Fangyu Liu, James Lee, Jue Chen
    The structures of ABCA4 in two conformations provide a framework to understand its transport mechanism.

    The sterol-responsive RNF145 E3 ubiquitin ligase mediates the degradation of HMG-CoA reductase together with gp78 and Hrd1

    Sam A Menzies, Norbert Volkmar ... Paul J Lehner
    CRISPR/Cas9 genome-wide screens using sterol-sensitive endogenous HMG-CoA reductase (HMGCR) reporter identify the sterol-responsive RNF145 and gp78 as independently responsible for sterol-accelerated degradation of HMGCR, the rate-limiting enzyme of cholesterol biosynthesis.

    A genome-wide view of the de-differentiation of central nervous system endothelial cells in culture

    Mark F Sabbagh, Jeremy Nathans
    In vitro culture of brain endothelial cells leads to a rapid loss of the blood-brain barrier transcriptional and accessible chromatin landscapes that is resistant to the effects of beta-catenin stabilization.

    Expression of SREBP-1c Requires SREBP-2-mediated Generation of a Sterol Ligand for LXR in Livers of Mice

    Shunxing Rong, Víctor A Cortés ... Jay D Horton
    SREBP-2 directly regulates genes involved in cholesterol homeostasis and indirectly regulates fatty acid synthesis through the production of a ligand responsible for the activation of LXR and SREBP-1c.

    Peroxisomal dysfunctions cause lysosomal storage and axonal Kv1 channel redistribution in peripheral neuropathy

    Sandra Kleinecke, Sarah Richert ... Celia Michèle Kassmann
    Dysfunctions of myelin peroxisomes cause a lysosomal storage-like disorder associated with alterations in glial and axonal membranes, which is the likely cause of nerve impairment in peroxisomal disorders.

    Inhibition of cholesterol biosynthesis through RNF145-dependent ubiquitination of SCAP

    Li Zhang, Prashant Rajbhandari ... Peter Tontonoz
    The E3 ubiquitin ligase RNF145 is shown to contribute to crosstalk between the LXR and SREBP-2 pathways in the regulation of cholesterol homeostasis.
