    Structure of cellular ESCRT-III spirals and their relationship to HIV budding

    Anil G Cashikar, Soomin Shim ... Phyllis I Hanson
    Electron microscopy on native membranes reveals the shape and potential function of protein machinery responsible for budding vesicles and viruses away from the cytoplasm.

    Area-specific development of distinct projection neuron subclasses is regulated by postnatal epigenetic modifications

    Kawssar Harb, Elia Magrinelli ... Christian Alfano
    Lmo4 specifies two neuron subclasses in the mouse neocortex by promoting postnatal co-expression of the transcription factors Ctip2 and Satb2 via chromatin remodelling in a time and area-specific manner.

    Loss of the transcription factor Meis1 prevents sympathetic neurons target-field innervation and increases susceptibility to sudden cardiac death

    Fabrice Bouilloux, Jérôme Thireau ... Frédéric Marmigère
    The transcription factor Meis1 is a dedicated maintenance factor for sympathetic neurons and controls the expression of key genes involved in endosome trafficking.

    Neuronal processing of noxious thermal stimuli mediated by dendritic Ca2+ influx in Drosophila somatosensory neurons

    Shin-Ichiro Terada, Daisuke Matsubara ... Tadao Usui
    Drosophila polymodal nociceptors use precipitous fluctuation of the firing rate, which depends on Ca2+ influx, as a key signal encoding a heat sensation and evoking the robust heat avoidance behavior.

    Activation of individual L1 retrotransposon instances is restricted to cell-type dependent permissive loci

    Claude Philippe, Dulce B Vargas-Landin ... Gaël Cristofari
    The expression of human L1 retrotransposons is highly locus-specific and variable between different cell types.

    The functional O-mannose glycan on α-dystroglycan contains a phospho-ribitol primed for matriglycan addition

    Jeremy L Praissman, Tobias Willer ... Lance Wells
    Disruption of the LG domain-binding phospho-ribitol-containing O-mannose structures on α-dystroglycan results in congenital muscular dystrophy.

    Diagnostic potential of tumor DNA from ovarian cyst fluid

    Yuxuan Wang, Karin Sundfeldt ... Bert Vogelstein
    Mutations in the DNA of ovarian cyst fluid can inform the need for surgery and indicate the type of neoplastic lesion present.

    QIL1 mutation causes MICOS disassembly and early onset fatal mitochondrial encephalopathy with liver disease

    Virginia Guarani, Claude Jardel ... Manuel Schiff
    Building on previous work (Guarani et al., 2015), MICOS (mitochondrial contact site) assembly and cristae junction formation are shown to have a critical role in human health.

    Phenotypic outcomes in Mouse and Human Foxc1 dependent Dandy-Walker cerebellar malformation suggest shared mechanisms

    Parthiv Haldipur, Derek Dang ... Kathleen J Millen
    Building on previous work (Haldipur et al., 2014), we show that many key mechanisms controlling cerebellar development are likely conserved between mouse and human, and validate our mouse model of Dandy-Walker malformation.

    Cilia-mediated Hedgehog signaling controls form and function in the mammalian larynx

    Jacqueline M Tabler, Maggie M Rigney ... John B Wallingford
    Genetic studies in mice reveal the molecular and embryological mechanisms of vocal fold development and function, thereby informing our understanding of vocal communication and congenital voice defects.
