    Impaired ABCA1/ABCG1-mediated lipid efflux in the mouse retinal pigment epithelium (RPE) leads to retinal degeneration

    Federica Storti et al.
    Lipid efflux by the retinal pigment epithelium is crucial for proper retinal integrity and function, and its impairment may contribute to diseases like age-related macular degeneration.

    The Arabidopsis transcription factor ABIG1 relays ABA signaled growth inhibition and drought induced senescence

    Tie Liu et al.
    Arabidopsis plants slow growth and jettison leaves in response to drought via a mechanism that involves the transcription factor ABIG1.

    LRP1 integrates murine macrophage cholesterol homeostasis and inflammatory responses in atherosclerosis

    Xunde Xian et al.
    Tyrosine phosphorylation of the intracellular domain of LRP1 serves as a molecular switch to regulate cellular cholesterol homeostasis through nuclear hormone receptor-mediated regulation of the cellular cholesterol exporter ABCA1.

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

    Shunxing Rong et al.
    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.

    The deca-GX3 proteins Yae1-Lto1 function as adaptors recruiting the ABC protein Rli1 for iron-sulfur cluster insertion

    Viktoria Désirée Paul et al.
    Two newly identified assembly factors for the ribosome-associated iron-sulfur protein Rli1 reveal a general mechanism for how the cytosolic iron-sulfur protein assembly (CIA) machinery recruits apoproteins.

    High-resolution mapping of fluoroquinolones in TB rabbit lesions reveals specific distribution in immune cell types

    Landry Blanc et al.
    Penetration of the fluoroquinolones in tuberculosis lesions is heterogeneous even in fully cellular areas, is driven by macrophage content and decreases as the distance from lesion outer rim increases.

    TAF4, a subunit of transcription factor II D, directs promoter occupancy of nuclear receptor HNF4A during post-natal hepatocyte differentiation

    Daniil Alpern et al.
    Physical and functional interactions between HNF4A and TAF4 coordinate HNF4A genomic occupancy with pre-initiation complex formation to activate post-natal hepatocyte gene expression.

    Release of cholesterol-rich particles from the macrophage plasma membrane during movement of filopodia and lamellipodia

    Xuchen Hu et al.
    Macrophages release 30-nm vesicular particles enriched in accessible cholesterol during cellular locomotion, a discovery that is likely relevant to cholesterol disposal by these cells.

    Continuous transport of a small fraction of plasma membrane cholesterol to endoplasmic reticulum regulates total cellular cholesterol

    Rodney Elwood Infante, Arun Radhakrishnan
    A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.
