    Autophagy linked FYVE (Alfy/WDFY3) is required for establishing neuronal connectivity in the mammalian brain

    Joanna M Dragich, Takaaki Kuwajima ... Ai Yamamoto
    Loss of function of the selective autophagy adaptor protein Alfy/Wdfy3 leads to profound wiring defects from the forebrain through to the spinal cord, highlighting the growing importance for macroautophagy in the developing brain.

    Histone supply regulates S phase timing and cell cycle progression

    Ufuk Günesdogan, Herbert Jäckle, Alf Herzig
    Controlling cell cycle progression in a developing embryo directly depends on de novo histone supply and a specialized surveillance mechanism for nucleosome assembly.

    A lipid bound actin meshwork organizes liquid phase separation in model membranes

    Alf Honigmann, Sina Sadeghi ... Richard Vink
    A combination of imaging experiments and computer simulations on a model lipid membrane integrate the 'picket fence' and 'raft' models, and suggest that the interplay between actin binding, lipid phase separation and curvature compartmentalize the membrane.

    Diverse stimuli engage different neutrophil extracellular trap pathways

    Elaine F Kenny, Alf Herzig ... Arturo Zychlinsky
    NETs induction, a central component of the innate immune response, utilises assorted signalling pathways as demonstrated through the analysis of healthy and patient neutrophils treated with five distinct stimuli.

    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego, Fernando Josa-Prado ... Maria A Oliva
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.

    Structure and ion-release mechanism of PIB-4-type ATPases

    Christina Grønberg, Qiaoxia Hu ... Pontus Gourdon
    A biochemical approach unveils the overall shape of a subclass of heavy-metal transporting pumps, thereby shedding light on principle molecular determinants linked to the transport mechanism of these elusive machines, information that is critical well beyond basic science.

    Biological brain age prediction using machine learning on structural neuroimaging data: Multi-cohort validation against biomarkers of Alzheimer’s disease and neurodegeneration stratified by sex

    Irene Cumplido-Mayoral, Marina García-Prat ... OASIS study
    Brain-Age delta is a non-invasive marker of biological brain aging that is sensitive to the presence of risk factors and altered biomarkers of Alzheimer's disease in non-demented individuals.

    Integrative dynamic structural biology unveils conformers essential for the oligomerization of a large GTPase

    Thomas-O Peulen, Carola S Hengstenberg ... Christian Herrmann
    Multimodal spectroscopy (smFRET, EPR, SAXS, and SANS) and integrative structural modeling reveal large-scale domain rearrangements in human guanylate binding protein 1 (hGBP1) that are driving forces for the formation of oligomers that enable its biological function in innate immune defense.

    Structural basis for activation and non-canonical catalysis of the Rap GTPase activating protein domain of plexin

    Yuxiao Wang, Heath G Pascoe ... Xuewu Zhang
    The crystal structures of the intracellular part of the plexin receptor in the active dimer form, and its complex with a key downstream signalling protein Rap, provide insights into how plexin initiates a signalling cascade involved in axon guidance.
