    Cryo-EM structure of the potassium-chloride cotransporter KCC4 in lipid nanodiscs

    Michelle S Reid et al.
    The structure of the potassium-chloride cotransporter KCC4 provides insight into the basis of ion specificity, transport stoichiometry, and activity regulation for a broadly physiologically and clinically important transporter family.

    Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM

    Gregory M Martin et al.
    Diverse KATP channel inhibitors occupy a common binding pocket and stabilize an interaction between Kir6.2 and SUR1 to allosterically control gating and promote the assembly and trafficking of nascent channels.

    Helical jackknives control the gates of the double-pore K+ uptake system KtrAB

    Marina Diskowski et al.
    The K(+) uptake system KtrAB is controlled by an allosteric mechanism entirely new for membrane channels, which operates the channel gate over a 35 Å distance.

    Evolution of cation binding in the active sites of P-loop nucleoside triphosphatases in relation to the basic catalytic mechanism

    Daria N Shalaeva et al.
    In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.

    ENaC-mediated sodium influx exacerbates NLRP3-dependent inflammation in cystic fibrosis

    Thomas Scambler et al.
    Dysfunction and overexpression of ENaC-mediated sodium influx exacerbates activation of NLRP3-inflammasome mediated inflammation in cells with CF-associated mutations and is modulated by inhibition of these amiloride-sensitive sodium (Na+) channels.
  1. Plain-language Summaries of Research: An inside guide to eLife digests

    Stuart RF King et al.

    Control of brown adipose tissue adaptation to nutrient stress by the activin receptor ALK7

    Patricia Marmol et al.
    The activin receptor ALK7 regulates the adaptation of brown adipose tissue to nutrient availability by preventing over-activation of signaling pathways induced by fasting, allowing appropriate response to cold exposure.

    Structural basis for ion selectivity in TMEM175 K+ channels

    Janine D Brunner et al.
    Structural and functional analysis of a recently discovered non-canonical potassium channel family reveals a unique selectivity filter that is exposed to permeating ions only in the conductive state.

    Human Neocortical Neurosolver (HNN), a new software tool for interpreting the cellular and network origin of human MEG/EEG data

    Samuel A Neymotin et al.
    Human Neocortical Neurosolver is a new user-friendly software tool for researchers to develop and test hypotheses on cellular/circuit origins of human MEG/EEG signals using a biophysical model.

    Purinergic signaling in cochlear supporting cells reduces hair cell excitability by increasing the extracellular space

    Travis A Babola et al.
    Supporting cells in the cochlea change their shape in response to purinergic receptor activation, which influences hair cell excitability by altering potassium redistribution in the extracellular space.
