    An elusive electron shuttle from a facultative anaerobe

    Emily Mevers et al.
    The identification of ACNQ as an extracellular electron shuttle solves a longstanding problem in bacterial physiology and provides new tool for bioenergy development.

    Stress-induced Cdk5 activity enhances cytoprotective basal autophagy in Drosophila melanogaster by phosphorylating acinus at serine437

    Nilay Nandi et al.
    Cdk5-mediated stabilization of Acinus in postmitotic neurons promotes autophagy and the removal of protein aggregates linked to neurodegeneration in Drosophila melanogaster.

    Noise-induced plasticity of KCNQ2/3 and HCN channels underlies vulnerability and resilience to tinnitus

    Shuang Li et al.
    Mice that successfully avoid developing tinnitus despite exposure to excessive noise show spontaneous recovery of KCNQ2/3 potassium channel activity associated with a reduction in HCN channel activity in auditory brainstem neurons.

    Domain–domain interactions determine the gating, permeation, pharmacology, and subunit modulation of the IKs ion channel

    Mark A Zaydman et al.
    Contrary to a generally accepted principle, the pore properties of KCNQ1 channels depend on the states of voltage-sensing domains activation; KCNE1 alters the voltage-sensing domains-pore coupling to modulate KCNQ1 channel properties.

    Translation attenuation by minocycline enhances longevity and proteostasis in old post-stress-responsive organisms

    Gregory M Solis et al.
    Directly targeting the ribosome to attenuate translation partly mimics the integrated stress response, increasing lifespan and preserving protein folding capacity even in older individuals with dysfunctional stress response signaling.

    ML277 specifically enhances the fully activated open state of KCNQ1 by modulating VSD-pore coupling

    Panpan Hou et al.
    ML277 exclusively enhances the AO state voltage-sensing domain (VSD)-pore coupling of KCNQ1 channels, providing an effective tool to investigate the voltge-dependent gating and new strategies for treating long QT syndrome.

    1. Neuroscience

    Vasoactive intestinal peptide-expressing interneurons are impaired in a mouse model of Dravet syndrome

    Kevin M Goff, Ethan M Goldberg
    Vasoactive intestinal peptide-expressing GABAergic interneurons in cerebral cortex express the sodium channel subunit Nav1.1, and a defined subset of VIP interneurons are dysfunctional in a mouse model of Dravet syndrome.
    1. Neuroscience

    Deletion of KCNQ2/3 potassium channels from PV+ interneurons leads to homeostatic potentiation of excitatory transmission

    Heun Soh et al.
    Loss of potassium channel activity from fast-spiking interneurons increases their excitability leading to unexpectedly increased fast excitatory transmission and seizure susceptibility.
