    Proteasome storage granules protect proteasomes from autophagic degradation upon carbon starvation

    Richard S Marshall, Richard D Vierstra
    Proteasomes are protected from autophagic elimination upon carbon starvation by sequestration into cytoplasmic storage granules, which aid cell fitness by providing a cache of proteasomes that can be rapidly remobilized when carbon availability improves.

    Learning place cells, grid cells and invariances with excitatory and inhibitory plasticity

    Simon Nikolaus Weber, Henning Sprekeler
    A large variety of spatial representations implied in rodent navigation could arise robustly and rapidly from inputs with a weak spatial structure, by an interaction of excitatory and inhibitory synaptic plasticity.

    Neurexin and Neuroligin-based adhesion complexes drive axonal arborisation growth independent of synaptic activity

    William D Constance et al.
    Axonal arborisation growth is regulated by dynamic, focal localisations of Neurexin and Neuroligin that provide stability for filopodia, enabling a 'stick and grow'-based mechanism, wholly independent of synapse formation.

    Conjunction of factors triggering waves of seasonal influenza

    Ishanu Chattopadhyay et al.
    Three complementary computational approaches reveal a set of putative causes of initiation of pan-USA waves of influenza.

    Pi-Pi contacts are an overlooked protein feature relevant to phase separation

    Robert McCoy Vernon et al.
    Statistics on the frequencies of pi interactions in folded protein structures enable successful prediction of intrinsically disordered protein phase separation, with clear implications for a physical understanding of cellular organization.

    Bipolar filaments of human nonmuscle myosin 2-A and 2-B have distinct motile and mechanical properties

    Luca Melli et al.
    Individual nonmuscle myosin 2 filaments in cells may differ their mechanical and kinetic properties depending on the myosin paralog composition giving the cells a mechanism for fine tuning the output of a given nonmuscle myosin filament.

    Activation of Toll-like receptors nucleates assembly of the MyDDosome signaling hub

    Sarah Louise Latty et al.
    The strength of Toll-like receptor signalling depends on the number and size of MyDDosomes formed as well as on how quickly these structures assemble.

    Gene-specific mechanisms direct glucocorticoid-receptor-driven repression of inflammatory response genes in macrophages

    Maria A Sacta et al.
    A comprehensive analysis of the glucocorticoid-sensitive pro-inflammatory genes in macrophages reveals fundamental differences between the temporal events and components of transcriptional machinery that the glucocorticoid receptor targets to repress their transcription.

    MERS-CoV spillover at the camel-human interface

    Gytis Dudas et al.
    MERS-CoV infections in the Arabian Peninsula are the result of several hundred spillover events from viruses circulating in camels into the human population.

    Regulation of posterior body and epidermal morphogenesis in zebrafish by localized Yap1 and Wwtr1

    David Kimelman et al.
    Analysis of a double mutant in the Hippo pathway transcription factors Yap1 and Wwtr1 reveals novel roles for these factors in posterior body formation and epidermal morphogenesis in the vertebrate embryo.
