    Epigenetic modulation of type-1 diabetes via a dual effect on pancreatic macrophages and β cells

    Wenxian Fu, Julia Farache ... Diane Mathis
    A short treatment of the NOD mouse model of type-1 diabetes with I-BET151, a small molecule bromodomain blocker, provides long-term protection from disease by inducing macrophages to adapt an anti-inflammatory tenor whilst promoting islet β cell regeneration.

    Expression noise facilitates the evolution of gene regulation

    Luise Wolf, Olin K Silander, Erik van Nimwegen
    In-lab evolution of synthetic promoters has revealed a novel general mechanism for de novo evolution of gene regulation, and highlights the crucial role of expression noise in this process.

    Perturbation biology nominates upstream–downstream drug combinations in RAF inhibitor resistant melanoma cells

    Anil Korkut, Weiqing Wang ... Chris Sander
    Data-driven systems biology models of signaling predict cellular response to untested perturbations and can nominate drug combinations to overcome drug resistance in cancer cells.

    Inhibitory IL-10-producing CD4+ T cells are T-bet-dependent and facilitate cytomegalovirus persistence via coexpression of arginase-1

    Mathew Clement, Kristin Ladell ... Ian R Humphreys
    The results presented here indicate that IL-10-producing CD4+ T cells express genes associated with chronically activated TH1-like cells, undergo clonal expansion, and inhibit antiviral T cell responses via the secretion of arginase-1, facilitating viral persistence in mice infected with MCMV.

    Modelling dynamics in protein crystal structures by ensemble refinement

    B Tom Burnley, Pavel V Afonine ... Piet Gros
    A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

    Natural killer (NK) cell-derived extracellular-vesicle shuttled microRNAs control T cell responses

    Sara G Dosil, Sheila Lopez-Cobo ... Lola Fernandez-Messina
    Extracellular vesicles derived from natural killer cells contain a specific repertoire of microRNAs that promote Th1 responses.
