    Mouse TRPA1 function and membrane localization are modulated by direct interactions with cholesterol

    Justyna B Startek et al.
    The activation and membrane localization of the broadly-tuned noxious chemosensory cation channel TRPA1 are regulated by direct interactions with cholesterol via CRAC motifs in transmembane segments 2 and 4.

    Impaired skeletal muscle mitochondrial pyruvate uptake rewires glucose metabolism to drive whole-body leanness

    Arpit Sharma et al.
    Skeletal muscle mitochondrial pyruvate carrier disruption increases muscle fatty acid oxidation and systemic glucose turnover that drive whole-body leanness.

    Misfolded GPI-anchored proteins are escorted through the secretory pathway by ER-derived factors

    Eszter Zavodszky, Ramanujan S Hegde
    ER-resident chaperones and cargo receptors make excursions to the cell surface and endocytic compartments when they accompany misfolded clients to lysosomes for degradation.

    Membrane insertion of α-xenorhabdolysin in near-atomic detail

    Evelyn Schubert et al.
    Cryo-EM and X-ray structures of α-xenorhabdolysin in soluble and pore form of Xenorhabdus nematophila give novel insights into the mechanism of action of bi-component α-pore-forming toxins.

    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.

    Presenilin mutations deregulate mitochondrial Ca2+ homeostasis and metabolic activity causing neurodegeneration in Caenorhabditis elegans

    Shaarika Sarasija et al.
    In C. elegans, presenilin functions, independent of its gamma-secretase proteolytic activity, to regulate mitochondrial metabolism by controlling ER-mitochondrial calcium transfer and, even in the absence of Abeta signaling, loss of this activity leads to neurodegeneration.

    Mitochondrial biogenesis is transcriptionally repressed in lysosomal lipid storage diseases

    King Faisal Yambire et al.
    Transcription factors KLF2 and ETV1 repress the transcriptional program of mitochondrial biogenesis, resulting in impaired mitochondrial function in lysosomal storage diseases.

    Mycobacterium tuberculosis induces decelerated bioenergetic metabolism in human macrophages

    Bridgette M Cumming et al.
    Quantifiable bioenergetic parameters, determined from extracellular flux analyses, are distinct between macrophages infected with Mycobacteriumtuberculosis or vaccine strain M. bovis BCG, enabling assessment of future vaccine and drug efficacy.

    Patched1 and Patched2 inhibit Smoothened non-cell autonomously

    Brock Roberts et al.
    Ptch1/2 can lower the sensitivity of Smo to activation by Shh via the secretion of a sterol precursor.

    v-SNARE transmembrane domains function as catalysts for vesicle fusion

    Madhurima Dhara et al.
    Structural flexibility of the synaptobrevin-2 transmembrane domain promotes membrane fusion.
