    Proteomics reveals synergy between biomass degrading enzymes and inorganic Fenton chemistry in leaf-cutting ant colonies

    Morten Schiøtt, Jacobus J Boomsma
    Leaf-cutting ants use their fecal fluid to vector enzymes produced by their fungal symbiont to degrade plant biomass with a combination of degradation enzymes and Fenton chemistry.

    Use of signals of positive and negative selection to distinguish cancer genes and passenger genes

    László Bányai, Maria Trexler ... László Patthy
    In contrast with earlier conclusions, negative selection has a major role in cancer evolution.

    Gut Helicobacter presentation by multiple dendritic cell subsets enables context-specific regulatory T cell generation

    Emilie V Russler-Germain, Jaeu Yi ... Chyi-Song Hsieh
    In vitro and in vivo studies show that multiple dendritic cell subsets are capable of presenting gut Helicobacter antigens to induce regulatory T cells.

    Generation of stress fibers through myosin-driven reorganization of the actin cortex

    Jaakko I Lehtimäki, Eeva Kaisa Rajakylä ... Pekka Lappalainen
    Live-cell microscopy studies revealed that stress fibers can be generated de novo from the actin cortex without the involvement of stress fiber precursors.

    Transsynaptic mapping of Drosophila mushroom body output neurons

    Kristin M Scaplen, Mustafa Talay ... Karla R Kaun
    Transsynaptic mapping of the postsynaptic connections of mushroom body output neurons reveal both divergent and convergent projections allowing for multimodal integration prior to initiation of an output response.

    The human origin recognition complex is essential for pre-RC assembly, mitosis, and maintenance of nuclear structure

    Hsiang-Chen Chou, Kuhulika Bhalla ... Bruce Stillman
    The initiation of human genome replication requires the six-subunit origin recognition complex (ORC) and CDC6, with ORC playing additional roles during mitosis and in organization of the cell nucleus.

    Charge-driven condensation of RNA and proteins suggests broad role of phase separation in cytoplasmic environments

    Bercem Dutagaci, Grzegorz Nawrocki ... Michael Feig
    Charge complementarity between RNA and proteins may be a universal principle for phase separation in biology without requiring disorder or specific multivalent interactions.

    Behavioral role of PACAP signaling reflects its selective distribution in glutamatergic and GABAergic neuronal subpopulations

    Limei Zhang, Vito S Hernandez ... Lee E Eiden
    Placing the PACAP/PAC1 signaling within glutamate/GABA cell type and subregional contexts in mouse brain reveals its conspicuous role for sensorimotor circuit interaction through modulating neuronal plasticity.

    Structure and mechanism of a phage-encoded SAM lyase revises catalytic function of enzyme family

    Xiaohu Guo, Annika Söderholm ... Maria Selmer
    The first structure of a bacteriophage-encoded S-adenosyl methionine degrading enzyme was solved and demonstrated to catalyze a unimolecular lyase reaction occurring at the domain interface of a trimeric structure.

    Induction of the IL-1RII decoy receptor by NFAT/FOXP3 blocks IL-1β-dependent response of Th17 cells

    Dong Hyun Kim, Hee Young Kim ... Won-Woo Lee
    Cellular immunological and biochemical analyses reveal how decoy IL-1RII is induced by human CD4+ T cells upon TCR-stimulation and regulates the Th17-Treg balance by modulating IL-1β responsiveness in IL-1RI+ cells.
