    Exceptional stability of a perilipin on lipid droplets depends on its polar residues, suggesting multimeric assembly

    Manuel Giménez-Andrés, Tadej Emeršič ... Alenka Čopič
    The amphipathic helix of perilipin 4 relies on the organization of its polar residues to form a remarkably immobile and stable protein layer on the surface of lipid droplets.

    Imaging cytoplasmic lipid droplets in vivo with fluorescent perilipin 2 and perilipin 3 knock-in zebrafish

    Meredith H Wilson, Stephen C Ekker, Steven A Farber
    Fluorescent perilipin zebrafish lines are powerful new tools for studying lipid droplet dynamics in health and disease.

    Human VPS13A is associated with multiple organelles and influences mitochondrial morphology and lipid droplet motility

    Wondwossen M Yeshaw, Marianne van der Zwaag ... Ody CM Sibon
    VPS13A is associated with the endoplasmic reticulum, mitochondria and lipid droplets and is required for cellular processes that require interaction between these organells.

    CPEB4 is regulated during cell cycle by ERK2/Cdk1-mediated phosphorylation and its assembly into liquid-like droplets

    Jordina Guillén-Boixet, Víctor Buzon ... Raúl Méndez
    CPEB4's switch from translational repressor to activator is regulated during cell cycle by hyperphosphorylation of its intrinsically disordered domain, which controls its phase-separation into RNA-containing liquid-like droplets.

    The large GTPase Sey1/atlastin mediates lipid droplet- and FadL-dependent intracellular fatty acid metabolism of Legionella pneumophila

    Dario Hüsler, Pia Stauffer ... Hubert Hilbi
    Intracellular growth of the bacterial pathogen Legionella pneumophila in the amoeba Dictyostelium discoideum implicates a bacterial fatty acid transporter as well as dynamic interactions of the distinct membrane-bound replication compartment with host cell lipid droplets.

    Dynamic metastable long-living droplets formed by sticker-spacer proteins

    Srivastav Ranganathan, Eugene I Shakhnovich
    Multi-scale simulations reveal a potential, ATP-independent mechanism resulting in the formation of the long-living multi-droplet state by multi-valent, spacer-sticker proteins.

    TFAP2 transcription factors are regulators of lipid droplet biogenesis

    Cameron C Scott, Stefania Vossio ... Jean Gruenberg
    The biogenesis of lipid droplets induced by Wnt3a is controlled by the transcription factor TFAP2, which presumably acts as a 'master' regulator of lipid droplet biogenesis.

    Lipid droplets and ferritin heavy chain: a devilish liaison in human cancer cell radioresistance

    Luca Tirinato, Maria Grazia Marafioti ... Joao Seco
    Lipid Droplet accumulation is a fingerprint shared by different human cancer radioresistant cells and their biogenesis strongly depend on FTH1 presence.

    A scale-invariant log-normal droplet size distribution below the critical concentration for protein phase separation

    Tommaso Amico, Samuel Toluwanimi Dada ... Amos Maritan
    The scaling invariance of the droplet size distribution as a universal aspect of protein phase separation is reported, providing a quantitative approach to determinate the critical concentration for this process.

    Centering and symmetry breaking in confined contracting actomyosin networks

    Niv Ierushalmi, Maya Malik-Garbi ... Kinneret Keren
    Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.
