    Large-scale state-dependent membrane remodeling by a transporter protein

    Wenchang Zhou, Giacomo Fiorin ... José D Faraldo-Gómez
    The conformational mechanism of a transporter protein is found to have profound and energetically costly effects on the morphology of the surrounding membrane.

    Membrane contact sites regulate vacuolar fission via sphingolipid metabolism

    Kazuki Hanaoka, Kensuke Nishikawa ... Kouichi Funato
    Sphingolipids regulate vacuolar fission via nuclear vacuole junction to adapt to intracellular and extracellular environments in budding yeast.

    The Caenorhabditis elegans Tubby homolog dynamically modulates olfactory cilia membrane morphogenesis and phospholipid composition

    Danielle DiTirro, Alison Philbrook ... Piali Sengupta
    A Tubby protein regulates ciliary membrane morphology and phosphoinositide composition in a context-dependent manner.

    Sphingomyelin metabolism controls the shape and function of the Golgi cisternae

    Felix Campelo, Josse van Galen ... Vivek Malhotra
    Association of curvature generating proteins to the Golgi membranes by sphingomyelin metabolism essentially controls the flatness of a Golgi cisterna that is necessary for efficient sorting and export.

    Cooperation of the ER-shaping proteins atlastin, lunapark, and reticulons to generate a tubular membrane network

    Songyu Wang, Hanna Tukachinsky ... Tom A Rapoport
    Experiments with mammalian cells and Xenopus egg extracts elucidate how three proteins cooperate to shape the reticular endoplasmic reticulum network.

    State-specific morphological deformations of the lipid bilayer explain mechanosensitive gating of MscS ion channels

    Yein Christina Park, Bharat Reddy ... José D Faraldo-Gómez
    A theory is presented that explains why some ion channels tend to open in response to membrane stretching, which posits that channel closing is disfavored by the morphological energetics of the lipid bilayer, and increasingly so under lateral tension.

    Revealing the distribution of transmembrane currents along the dendritic tree of a neuron from extracellular recordings

    Dorottya Cserpán, Domokos Meszéna ... Daniel K Wójcik
    A computational method reveals current sources along the dendritic tree of a single neuron of known morphology from extracellular potential.

    Long-term adult human brain slice cultures as a model system to study human CNS circuitry and disease

    Niklas Schwarz, Betül Uysal ... Henner Koch
    Viral transduction and gene manipulation of adult human brain slices will be of great value allowing investigations including therapeutic screening, electrophysiological and structural studies of properties of human CNS circuitry.

    QIL1 is a novel mitochondrial protein required for MICOS complex stability and cristae morphology

    Virginia Guarani, Elizabeth M McNeill ... J Wade Harper
    A comprehensive analysis of the human MICOS complex has identified a novel subunit called QIL1 that is required for cristae junction formation in human cells and Drosophila, through its role in the assembly of the MICOS complex.
    1. Neuroscience

    When complex neuronal structures may not matter

    Adriane G Otopalik, Alexander C Sutton ... Eve Marder
    Animal-to-animal variability in neuronal geometry may be compensated for by compact electrotonic structure.
