    Oligodendrocytes control potassium accumulation in white matter and seizure susceptibility

    Valerie A Larson et al.
    Oligodendrocytes in white matter use Kir4.1 inwardly rectifying potassium channels to prevent extracellular potassium accumulation, enabling neurons to sustain repetitive firing and limiting the initiation of seizures.

    Molecular structure of human KATP in complex with ATP and ADP

    Kenneth Pak Kin Lee et al.
    MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.

    Anti-diabetic drug binding site in a mammalian KATP channel revealed by Cryo-EM

    Gregory M Martin et al.
    A structure of a pancreatic ATP-sensitive potassium channel complex at 3.63Å resolution obtained by cryo-electron microscopy reveals how a commonly used anti-diabetic drug interacts with and inhibits the channel to stimulate insulin secretion.

    Ion Channels: From ions to insulin

    Voula Kanelis
    Electron cryo-microscopy has revealed the three-dimensional structure of a potassium channel that has a central role in regulating the release of insulin from the pancreas.

    Inhibition of Transient Receptor Potential Melastatin 3 ion channels by G-protein βγ subunits

    Doreen Badheka et al.
    Electrophysiological experiments, Ca2+ imaging, and behavioral studies in mice identify the TRPM3 ion channel as a novel target of G-protein βγ subunits.

    Mutations in L-type amino acid transporter-2 support SLC7A8 as a novel gene involved in age-related hearing loss

    Meritxell Espino Guarch et al.
    SLC7A8 a neutral amino acid transporter has a key role in the maintenance of hearing during aging and its absence causes early onset of hearing loss.

    Immediate perception of a reward is distinct from the reward’s long-term salience

    John P McGinnis et al.
    The experiences that are most rewarding at the time are not necessarily those that are remembered long-term.

    Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

    Hongkang Zhang et al.
    Optogenetic tools enable sophisticated measurements of a voltage-gated sodium channel implicated in pain, as well as high-throughput screening of candidate channel blockers.

    BAD and KATP channels regulate neuron excitability and epileptiform activity

    Juan Ramón Martínez-François et al.
    Altered activity of ATP-sensitive K+ channels underlies the metabolic seizure resistance produced by genetic manipulation of the BAD protein in mice.

    Peptidoglycan sensing by octopaminergic neurons modulates Drosophila oviposition

    C Leopold Kurz et al.
    Female fruit flies sense bacteria-derived peptidoglycan via the octopaminergic neurons to adapt their egg laying behavior to their infection status.
