    Stepwise visualization of membrane pore formation by suilysin, a bacterial cholesterol-dependent cytolysin

    Carl Leung et al.
    Electron and atomic force microscopy show how bacterial toxins bind to a host membrane and assemble into arcs and rings, before undergoing a dramatic, concerted conformational change to insert into the membrane.

    CryoEM structures of membrane pore and prepore complex reveal cytolytic mechanism of Pneumolysin

    Katharina van Pee et al.
    The near-atomic cryoEM pore complex structure of pneumolysin, the main virulence factor of Streptococcus pneumoniae, shows how the individual domains rearrange during the pore formation.

    Single molecule compression reveals intra-protein forces drive cytotoxin pore formation

    Daniel M Czajkowsky et al.
    Compressive force spectroscopy of single molecules reveals that intra-protein forces underlie the long-distance coordination of structural changes within a cytotoxin during pore formation.

    GPIHBP1 expression in gliomas promotes utilization of lipoprotein-derived nutrients

    Xuchen Hu et al.
    The expression of the lipoprotein lipase (LPL) transporter GPIHBP1 in glioma capillaries promotes the LPL-mediated processing of triglyceride-rich lipoproteins, thereby providing lipid nutrients for glioma cells.

    Release of cholesterol-rich particles from the macrophage plasma membrane during movement of filopodia and lamellipodia

    Xuchen Hu et al.
    Macrophages release 30-nm vesicular particles enriched in accessible cholesterol during cellular locomotion, a discovery that is likely relevant to cholesterol disposal by these cells.

    Membrane insertion of α-xenorhabdolysin in near-atomic detail

    Evelyn Schubert et al.
    Cryo-EM and X-ray structures of α-xenorhabdolysin in soluble and pore form of Xenorhabdus nematophila give novel insights into the mechanism of action of bi-component α-pore-forming toxins.

    A non canonical subtilase attenuates the transcriptional activation of defence responses in Arabidopsis thaliana

    Irene Serrano et al.
    An atypical subtilase protein, resulting from an alternative splicing event, mediates retention of the defence related-transcription factor MYB30 at endosomal vesicles, thus repressing Arabidopsis antibacterial immunity.

    Enteric pathogens deploy cell cycle inhibiting factors to block the bactericidal activity of Perforin-2

    Ryan M McCormack et al.
    Yersinia pseudotuberculosis and enteropathogenic Escherichia coli promote pathogenicity by deamidating the ubiquitin-like protein NEDD8 to block ubiquitin-dependent trafficking of Perforin-2, which is an effector of innate immunity.

    Three pools of plasma membrane cholesterol and their relation to cholesterol homeostasis

    Akash Das et al.
    Precise control of cellular cholesterol levels is achieved by organization of cholesterol into three distinct pools in the plasma membrane.
