    Delta glutamate receptor conductance drives excitation of mouse dorsal raphe neurons

    Stephanie C Gantz, Khaled Moussawi, Holly S Hake
    In mouse brain slices, native delta glutamate receptors carry ionic current and underlie the α1-adrenergic receptor-mediated depolarization of dorsal raphe neurons that drives action potential firing in vivo.

    SPARK regulates AGC kinases central to the Toxoplasma gondii asexual cycle

    Alice L Herneisen, Michelle L Peters ... Sebastian Lourido
    Genetic and proteomic analyses reveal that the SPARK kinase, which is a regulator of key life-cycle transitions in the parasite Toxoplasma gondii, complexes with an elongin-like protein to regulate several important AGC-family kinases.

    Single-cell transcriptome profiles of Drosophila fruitless-expressing neurons from both sexes

    Colleen M Palmateer, Catherina Artikis ... Michelle N Arbeitman
    A single-cell RNA-seq study examining gene expression profiles in neurons that underlie Drosophila reproductive behaviors shows males and females build sex-specific behaviors at the molecular-genetic level by overlaying sex-specific information on core gene expression networks.

    Mechanical force of uterine occupation enables large vesicle extrusion from proteostressed maternal neurons

    Guoqiang Wang, Ryan J Guasp ... Monica Driscoll
    Large extracellular vesicle extrusion that eliminates neuronal protein aggregates and organelles is potentiated by uterine filling, linking reproductive status to maternal nervous system health, and demonstrating mechanobiology components in exophergenesis.

    Single-cell expression profiling reveals dynamic flux of cardiac stromal, vascular and immune cells in health and injury

    Nona Farbehi, Ralph Patrick ... Richard P Harvey
    Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.

    Enhancing and inhibitory motifs regulate CD4 activity

    Mark S Lee, Peter J Tuohy ... Michael S Kuhns
    Eutherian CD4 evolved counterbalancing motifs in the extracellular, transmembrane, and intracellular domains that regulate CD4+ T cell responses to peptide antigens presented by class II MHC (pMHCII).

    Medial orbitofrontal inactivation does not affect economic choice

    Matthew PH Gardner, Jessica C Conroy ... Geoffrey Schoenbaum
    Inactivation of the medial orbitofrontal cortex using an optogenetic approach did not affect behavior in rats on an iconic economic choice task.
