    Histone H2B ubiquitylation represses gametogenesis by opposing RSC-dependent chromatin remodeling at the ste11 master regulator locus

    Philippe Materne, Enrique Vázquez ... Damien Hermand
    Building on previous work (Materne et al., 2015), it is shown that the ubiquitylation of histone H2B represses cell differentiation by opposing chromatin remodeling at the promoter of the master regulator of gametogenesis, ste11

    Ataxin-1 oligomers induce local spread of pathology and decreasing them by passive immunization slows Spinocerebellar ataxia type 1 phenotypes

    Cristian A Lasagna-Reeves, Maxime WC Rousseaux ... Huda Y Zoghbi
    Building on previous work (Lasagna-Reeves et al., 2015) it is shown that polyglutamine ATXN1 oligomers propagate locally in SCA1 mice, and that passive immunotherapy targeting soluble oligomers can lead to an improvement in motor coordination and a modest increase in life span.

    Elevation of CpG frequencies in influenza A genome attenuates pathogenicity but enhances host response to infection

    Eleanor Gaunt, Helen M Wise ... Peter Simmonds
    Mutants of influenza A virus with increased CpG dinucleotide frequencies show restricted replication and reduced or absent pathogenicity, and powerful host innate and adaptive responses to infection that confer immunity to re-infection.

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    Multimodal sensory integration in single cerebellar granule cells in vivo

    Taro Ishikawa, Misa Shimuta, Michael Häusser
    Building on previous work (Huang et al., 2013), it is shown that single granule cells receive excitatory synaptic input driven by up to three separate sensory modalities in vivo, which demonstrate that individual neurons can contribute to multisensory integration at the input layer of the cerebellar cortex.
    1. Neuroscience

    Dbx1 precursor cells are a source of inspiratory XII premotoneurons

    Ann L Revill, Nikolas C Vann ... Gregory D Funk
    Building on previous work (Wang et al., 2014), we use a combination of genetic, electrophysiology and laser ablation approaches to identify a developmentally defined population of neurons that are a significant source of clinically relevant inspiratory drive to XII motoneurons.
    1. Neuroscience

    Lateral orbitofrontal neurons acquire responses to upshifted, downshifted, or blocked cues during unblocking

    Nina Lopatina, Michael A McDannald ... Geoffrey Schoenbaum
    Building on previous work (McDannald et. al, 2014), it is shown that dissociable populations of neurons in the lateral orbitofrontal cortex acquire responses to cues that predict more, less, or no change in reward in rats during training in a Pavlovian unblocking task.

    TANGO1 recruits ERGIC membranes to the endoplasmic reticulum for procollagen export

    António JM Santos, Ishier Raote ... Vivek Malhotra
    Building on previous work (Nogueira et al., 2014), we describe a mechanism for the generation of a mega-carrier for the export of bulky procollagen from the endoplasmic reticulum.
    1. Neuroscience

    Modulation of GABA and resting state functional connectivity by transcranial direct current stimulation

    Velicia Bachtiar, Jamie Near ... Charlotte J Stagg
    Building on previous work (Stagg et al., 2014), it is shown that transcranial direct current stimulation modulates local GABA concentration and functional connectivity in the human motor cortex.

    Re-examining the role of Drosophila Sas-4 in centrosome assembly using two-colour-3D-SIM FRAP

    Paul T Conduit, Alan Wainman ... Jordan W Raff
    Building on previous work (Conduit et al., 2014), and contrary to what was previously thought, it is shown that key centrosomal proteins are not recruited to centrosomes as part of large multi-protein assemblies.
