    Structural insights into regulation of CNNM-TRPM7 divalent cation uptake by the small GTPase ARL15

    Luba Mahbub, Guennadi Kozlov ... Kalle Gehring
    ADP-ribosylation factor-like GTPase 15, an atypical small GTPase, binds to cystathionine-β-synthase-pair domain divalent metal cation transport mediator (CNNM) membrane proteins to inhibit divalent cation efflux by CNNM proteins and influx by transient receptor potential ion channel subfamily M member 7.

    Widespread mermithid nematode parasitism of Cretaceous insects

    Cihang Luo, George O Poinar ... Bo Wang
    Sixteen new mermithid nematodes associated with their insect hosts are discovered from mid-Cretaceous Kachin amber and they are more abundant in non-holometabolous insect hosts, revealing what appears to be a vanished history of nematodes parasitism.

    Opto-RhoGEFs, an optimized optogenetic toolbox to reversibly control Rho GTPase activity on a global to subcellular scale, enabling precise control over vascular endothelial barrier strength

    Eike K Mahlandt, Sebastián Palacios Martínez ... Joachim Goedhart
    Optogenetic activation of Rho GTPases provides spatiotemporal control over endothelial cell shape and enables control over endothelial barrier function by manipulating the cell-cell overlap with blue light.

    Longitudinal map of transcriptome changes in the Lyme pathogen Borrelia burgdorferi during tick-borne transmission

    Anne L Sapiro, Beth M Hayes ... Seemay Chou
    Development of an enrichment method to facilitate RNA-sequencing of the Lyme disease pathogen from inside of ticks during a bloodmeal provides new candidates for genes important for disease transmission.

    Low-level repressive histone marks fine-tune gene transcription in neural stem cells

    Arjun Rajan, Lucas Anhezini ... Cheng-Yu Lee
    Stem-cell-specific transcriptional repressors fine-tune levels of stemness gene transcripts in asymmetrically dividing neural stem cells by depositing low levels of repressive histone marks at these loci allowing progeny to rapidly initiate differentiation.

    Rapid, automated, and experimenter-free touchscreen testing reveals reciprocal interactions between cognitive flexibility and activity-based anorexia in female rats

    Kaixin Huang, Laura K Milton ... Claire J Foldi
    An automated touchscreen cognitive testing system for rats reduces the length of training required to learn tasks, making it possible to assess cognitive profiles in adolescent animals to more appropriately capture cognitive deficits in adolescent pathologies, such as anorexia nervosa.

    Importance of glutamine in synaptic vesicles revealed by functional studies of SLC6A17 and its mutations pathogenic for intellectual disability

    Xiaobo Jia, Jiemin Zhu ... Yi Rao
    Physiological studies of SLC6A17 and its pathogenic mutations revealed that glutamine is transported into synaptic vesicles (SVs) in an SLC6A17-dependent manner and all pathogenic conditions reduced glutamine level in SVs.

    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.

    Sterol derivative binding to the orthosteric site causes conformational changes in an invertebrate Cys-loop receptor

    Steven De Gieter, Casey I Gallagher ... Rouslan G Efremov
    Cryo-EM structures of Cys-loop receptor Alpo4 from the thermophilic worm Alvinella pompejana show that a sterol derivative CHAPS binds in and outside of its orthosteric binding site and induces a quaternary twist.
