    Cryo-EM structures of the DCPIB-inhibited volume-regulated anion channel LRRC8A in lipid nanodiscs

    David M Kern et al.
    The basis for small-molecule block, insights into gating, and an unexpected architectural role for the lipid membrane are revealed in structures of the volume regulated anion channel LRRC8A.

    A FRET sensor of C-terminal movement reveals VRAC activation by plasma membrane DAG signaling rather than ionic strength

    Benjamin König et al.
    VRAC activation, observed with a FRET sensor of intracellular LRRC8-domains movement during gating and by fluorometry, requires plasma membrane localization and diacylglycerol signaling, but is independent of intracellular ionic strength.

    LRRC8A is essential for hypotonicity-, but not for DAMP-induced NLRP3 inflammasome activation

    Jack P Green et al.
    Depletion of LRRC8A provides genetic evidence for the importance of Cl- channels in NLRP3 activation.

    The SWELL1-LRRC8 complex regulates endothelial AKT-eNOS signaling and vascular function

    Ahmad F Alghanem et al.
    SWELL1 is required for basal, stretch, and flow-mediated endothelial AKT-eNOS signaling in vitro and protects against angiotensin-induced hypertension and diabetes-associated vascular dysfunction in vivo.

    Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE

    Yao Li et al.
    A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.

    The fluoride permeation pathway and anion recognition in Fluc family fluoride channels

    Benjamin C McIlwain et al.
    In the extremely selective fluoride channels from the bacterial Fluc family, fluoride ions access the pore via two points, an electropositive vestibule and a triad of conserved residues involved in anion recognition.

    Biophysical models reveal the relative importance of transporter proteins and impermeant anions in chloride homeostasis

    Kira M Düsterwald et al.
    Mathematical models with experimental validation show that chloride transporters in the cell membrane, and not negatively charged impermeant molecules, generate the driving force used by GABA receptors to silence neurons.
