    Neuronal hyperexcitability is a DLK-dependent trigger of herpes simplex virus reactivation that can be induced by IL-1

    Sean R Cuddy, Austin R Schinlever ... Anna R Cliffe
    Herpes simplex virus reactivates from a latent infection when neurons become hyperexcitable in response to an inflammatory cytokine known to be released during fever and stress.

    Targeted deletion of AKAP7 in dentate granule cells impairs spatial discrimination

    Brian W Jones, Jennifer Deem ... G Stanley McKnight
    The PKA anchoring protein, AKAP7, localizes PKA in dentate granule mossy fibers and this localization plays an important role in contextual discrimination and cAMP-induced synaptic plasticity.

    Inflammation produces catecholamine resistance in obesity via activation of PDE3B by the protein kinases IKKε and TBK1

    Jonathan Mowers, Maeran Uhm ... Alan R Saltiel
    Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.

    Pharmacological evidence for a metabotropic glutamate receptor heterodimer in neuronal cells

    David Moreno Delgado, Thor C Møller ... Jean-Philippe Pin
    Innovative approaches were used to identify the specific pharmacological properties of heterodimeric metabotropic glutamate receptors composed of mGlu2 and mGlu4 subunits, and reveal their existence in a neuronal cell line and in perforant path terminals.

    GPCR signaling inhibits mTORC1 via PKA phosphorylation of Raptor

    Jenna L Jewell, Vivian Fu ... Kun-Liang Guan
    Protein kinase A (PKA) phosphorylates Raptor and inhibits mammalian target of rapamycin complex 1 (mTORC1) activity.

    Structural and functional characterization of G protein–coupled receptors with deep mutational scanning

    Eric M Jones, Nathan B Lubock ... Sriram Kosuri
    Linking deep mutational scanning with engineered transcriptional reporters in human cell lines establishes a generalizable method for exploring pharmacogenomics, structure, and function across broad classes of drug receptors.

    cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool

    Vladimir Camarena, David W Sant ... Gaofeng Wang
    cAMP is identified to play a novel role in regulating DNA demethylation and gene transcription by augmenting the intracellular reactive Fe(II) pool.

    Nanobody-directed targeting of optogenetic tools to study signaling in the primary cilium

    Jan N Hansen, Fabian Kaiser ... Dagmar Wachten
    Trafficking of optogenetic tools to primary cilia using nanobodies allows to study cAMP signaling with spatial and temporal resolution independent of the cell body.
    1. Developmental Biology

    An adhesion G protein-coupled receptor is required in cartilaginous and dense connective tissues to maintain spine alignment

    Zhaoyang Liu, Amro A Hussien ... Ryan S Gray
    The regulation of the biomechanical properties of tendons/ligaments is essential for the maintenance of spine alignment in the mouse.
