    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.

    Electron cryo-microscopy of bacteriophage PR772 reveals the elusive vertex complex and the capsid architecture

    Hemanth KN Reddy et al.
    The structure and composition of the elusive vertex complex in Tectiviridae is finally revealed and the newly reported protein conformations help to maintain the capsid architecture.

    Accelerated phosphatidylcholine turnover in macrophages promotes adipose tissue inflammation in obesity

    Kasparas Petkevicius et al.
    Obesity leads to increased phosphatidylcholine turnover in adipose tissue macrophages that makes them susceptible to saturated fatty acid-induced inflammation.

    Composition and structure of synaptic ectosomes exporting antigen receptor linked to functional CD40 ligand from helper T cells

    David G Saliba et al.
    TCR and CD40L microclusters are linked in synaptic ectosomes (extracellular vesicles) and released in the immunological synapse by helper T cells and induce dendritic cell maturation and cytokine production.

    A critical role of VMP1 in lipoprotein secretion

    Hideaki Morishita et al.
    The ER transmembrane protein VMP1 is important for release of lipoproteins from the ER membrane into the ER lumen for secretion.

    Mechanisms of iron- and O2-sensing by the [4Fe-4S] cluster of the global iron regulator RirA

    Ma Teresa Pellicer Martinez et al.
    Molecular details of how the iron–sulfur cluster cofactor of a bacterial global iron regulatory protein simultaneously senses iron and O2 are revealed by mass spectrometry and spectroscopy.

    Natural selection and repeated patterns of molecular evolution following allopatric divergence

    Yibo Dong et al.
    The genomic architecture of allopatric species is a mosaic of many conserved genes and a few adaptive ones, reflecting balance between conservation of ancestral functions and evolution of new features.

    Noroviruses subvert the core stress granule component G3BP1 to promote viral VPg-dependent translation

    Myra Hosmillo et al.
    A key cellular stress granule protein, G3BP1, is critical for efficient norovirus infection, representing the first pan-norovirus, pro-viral factor identified to date.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Apicomplexan-like parasites are polyphyletic and widely but selectively dependent on cryptic plastid organelles

    Jan Janouškovec et al.
    Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.
