    Phospholipase D activity couples plasma membrane endocytosis with retromer dependent recycling

    Rajan Thakur et al.
    Phosphatidic acid regulates recycling of endocytosed plasma membrane vesicles in polarized cells through a retromer and Arf1 dependent process.

    Membrane fluidity is regulated by the C. elegans transmembrane protein FLD-1 and its human homologs TLCD1/2

    Mario Ruiz et al.
    Inhibition of C. elegans FLD-1 or Human TLCD1/2 prevents saturated fat lipotoxicity by allowing increased levels of membrane phospholipids that contain fluidizing long-chain polyunsaturated fatty acids.

    Phosphatidylcholines from Pieris brassicae eggs activate an immune response in Arabidopsis

    Elia Stahl et al.
    Plants detect the presence of phospholipids in eggs from a herbivorous insect and trigger innate immunity.

    Molecular basis of fatty acid taste in Drosophila

    Ji-Eun Ahn et al.
    Molecular-genetic, neural imaging and behavioral analyses reveal how Drosophila melanogaster sense fatty acids, important nutrient compounds, through multimeric Ionoptropic Receptors complexes.

    Golgi localized β1-adrenergic receptors stimulate Golgi PI4P hydrolysis by PLCε to regulate cardiac hypertrophy

    Craig A Nash et al.
    β-adrenergic receptors at the Golgi apparatus activate a local signaling pathway, not accessed by cell surface receptors, to drive cardiac hypertrophy and could represent a target for heart failure therapy.

    Phosphatidic acid modulation of Kv channel voltage sensor function

    Richard K Hite et al.
    Phosphatidic acid influences the gating of voltage-gated K+ channels through a non-specific surface charge mechanism and through a specific interaction between a voltage sensor arginine and the primary phosphate head group on the cytoplasmic membrane leaflet.

    Repression of viral gene expression and replication by the unfolded protein response effector XBP1u

    Florian Hinte et al.
    A herpesvirus harnesses the unfolded protein response to regulate its own life cycle, revealing an unexpected role of XBP1u as a potent repressor of the most important viral promoter.

    Identification of a bilirubin receptor that may mediate a component of cholestatic itch

    James Meixiong et al.
    MRGPRX4 is a bilirubin receptor that may be a therapeutic target for patients suffering from cholestatic itch.

    Connexin-43-dependent ATP release mediates macrophage activation during sepsis

    Michel Dosch et al.
    Autocrine activation of macrophages is modulated by Connexin-43-mediated ATP release in response to TLR-4 and -2 agonists in a P2Y1-dependent manner, ultimately determining sepsis survival.
