    Onset of taste bud cell renewal starts at birth and coincides with a shift in SHH function

    Erin J Golden et al.
    Taste cell renewal begins at birth and is promoted by sonic hedgehog that alters the expression of regulators of cell migration and adhesion that may allow entry of new cells into buds.

    The Ca2+ transient as a feedback sensor controlling cardiomyocyte ionic conductances in mouse populations

    Colin M Rees et al.
    Feedback sensing of the intracellular calcium concentration suffices to reproduce the diversity of ionic conductances underlying normal cardiac electromechanical function in a genetically diverse population of mice.

    Infant and adult SCA13 mutations differentially affect Purkinje cell excitability, maturation, and viability in vivo

    Jui-Yi Hsieh et al.
    Electrophysiological analysis and imaging in live zebrafish reveal that infant- and adult-onset SCA13 mutations have distinct effects on the electrical activity, development, and survival of cerebellar Purkinje cells.

    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.

    BK channel inhibition by strong extracellular acidification

    Yu Zhou et al.
    Analysis of iconic and gating currents of wild type and mutated BK channels reveals a strong inhibition of this channel by extracellular acidification and elucidates the underlying mechanism that is potentially applicable to other voltage-dependent cation channels.

    Identification of a lipid scrambling domain in ANO6/TMEM16F

    Kuai Yu et al.
    The amino acids that are necessary for phospholipid scrambling by ANO6/TMEM16F can, via domain swapping, confer scrambling activity to the chloride ion channel ANO1 that normally does not scramble phospholipids.

    Temperature compensation in a small rhythmic circuit

    Leandro M Alonso, Eve Marder
    Computational models demonstrate that circuit resilience to temperature perturbations are associated with smooth transitions between cellular mechanisms as the contributions of different currents are altered while activity is maintained.

    Clusters of cooperative ion channels enable a membrane-potential-based mechanism for short-term memory

    Paul Pfeiffer et al.
    Independently gating ion channels typically act fast within milliseconds, but cooperative interactions within a cluster of channels allow for a memory of previous electrical activity for several seconds.

    Development, calibration, and validation of a novel human ventricular myocyte model in health, disease, and drug block

    Jakub Tomek et al.
    A computer model of human cardiomyocyte was produced and validated on independent datasets, overcoming shortcomings of its predecessors, also yielding broadly relevant insights and results on major ionic currents.
