    Pathogen infection and cholesterol deficiency activate the C. elegans p38 immune pathway through a TIR-1/SARM1 phase transition

    Nicholas D Peterson, Janneke D Icso ... Read Pukkila-Worley
    A phase transition of TIR-1/SARM1 induced by either pathogen or non-pathogen stress potentiates its intrinsic NADase activity, which activates the p38 PMK-1 signaling cascade to induce protective immune defenses in Caenorhabditis elegans intestinal epithelial cells.

    Differential modification of the C-terminal tails of different α-tubulins and their importance for microtubule function in vivo

    Mengjing Bao, Ruth E Dörig ... Beat Suter
    Specific glutamylation of some α-tubulin isotypes affects kinesin-1 localization and transport processes that depend on it, but their absence can speed up transport, possibly explaining why some large cells express α-tubulin isotypes that are not glutamylated.

    Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM

    Gregory M Martin, Min Woo Sung ... Show-Ling Shyng
    Diverse KATP channel inhibitors occupy a common binding pocket and stabilize an interaction between Kir6.2 and SUR1 to allosterically control gating and promote the assembly and trafficking of nascent channels.

    A lncRNA identifies Irf8 enhancer element in negative feedback control of dendritic cell differentiation

    Huaming Xu, Zhijian Li ... Martin Zenke
    A novel lncRNA marks the Irf8 downstream enhancer that is crucial for differentiation of plasmacytoid dendritic cells (pDC) and classical dendritic cells type 1 (cDC1) and confers feedback inhibition of Irf8 transcription.

    Malaria parasites use a soluble RhopH complex for erythrocyte invasion and an integral form for nutrient uptake

    Marc A Schureck, Joseph E Darling ... Sanjay A Desai
    A high-resolution structure reveals how the RhopH complex traffics within Plasmodium-infected human erythrocytes to serve divergent, essential functions.

    SETD3 protein is the actin-specific histidine N-methyltransferase

    Sebastian Kwiatkowski, Agnieszka K Seliga ... Jakub Drozak
    Histone-lysine N-methyltransferase SETD3 (NP_115609.2) was identified as the actin-specific histidine N-methyltransferase, an enzyme catalyzing the extremely well-conserved methylation of H73 in β-actin.

    Diversification of heart progenitor cells by EGF signaling and differential modulation of ETS protein activity

    Benjamin Schwarz, Dominik Hollfelder ... Ingolf Reim
    A novel regulatory model for the diversification of cardiac cell subpopulations in Drosophila is established by linking epidermal growth factor signaling with differential activities of key transcription factors.

    The East Asian gut microbiome is distinct from colocalized White subjects and connected to metabolic health

    Qi Yan Ang, Diana L Alba ... Peter J Turnbaugh
    The gut microbiota of East Asians is distinct, dissociated from body mass, and self-sustains compared to White subjects from the same region, and therein may underpin a key health disparity.

    Homeostatic regulation of rapid eye movement sleep by the preoptic area of the hypothalamus

    John J Maurer, Alexandra Lin ... Shinjae Chung
    Preoptic area of the hypothalamus is important for the homeostatic regulation of rapid eye movement sleep.

    Scavenger receptor endocytosis controls apical membrane morphogenesis in the Drosophila airways

    Ana Sofia Pinheiro, Vasilios Tsarouhas ... Christos Samakovlis
    During tracheal morphogenesis, the scavenger receptor Emp senses and responds to luminal cargo levels by initiating apical membrane endocytosis along the longitudinal tube axis to restrict airway elongation.
