    Delta glutamate receptor conductance drives excitation of mouse dorsal raphe neurons

    Stephanie C Gantz et al.
    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.

    Adrenergic activation modulates the signal from the Reissner fiber to cerebrospinal fluid-contacting neurons during development

    Yasmine Cantaut-Belarif et al.
    The Reissner fiber in the cerebrospinal fluid is required for a signal integrated by developing sensory neurons and modulated by catecholamines to control the embryo posterior axis morphogenesis.

    Neural signatures of α2-Adrenergic agonist-induced unconsciousness and awakening by antagonist

    Jesus Javier Ballesteros et al.
    Instant performance recovery is possible following general anesthesia-induced unconsciousness using antagonist, and the brain dynamics return abruptly to the awake state without intermediate recovery states.

    Synthetic single domain antibodies for the conformational trapping of membrane proteins

    Iwan Zimmermann et al.
    Synthetic single domain antibody libraries and a binder selection cascade encompassing ribosome and phage display enable the selection of conformation-specific binders against previously intractable membrane proteins within three weeks.

    Molecular basis of signaling specificity between GIRK channels and GPCRs

    Kouki K Touhara, Roderick MacKinnon
    A single kinetic step in the G protein activation cycle determines whether a G protein-coupled receptor activates G protein-gated K+ channels or not.

    Super-resolution microscopy reveals majorly mono- and dimeric presenilin1/γ-secretase at the cell surface

    Abril Angélica Escamilla-Ayala et al.
    Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.

    Synaptic plasticity through activation of GluA3-containing AMPA-receptors

    Maria C Renner et al.
    A novel form of hippocampal synaptic plasticity is expressed by a change in channel function of GluA3-containing AMPA-receptors.

    ANGPTL4 mediates shuttling of lipid fuel to brown adipose tissue during sustained cold exposure

    Wieneke Dijk et al.
    During sustained cold exposure, lipid fuel is specifically directed towards brown adipose tissue, but not white adipose tissue, via cold-induced regulation of Angiopoietin-like 4 (ANGPTL4).

    Intrinsic disorder within an AKAP-protein kinase A complex guides local substrate phosphorylation

    F Donelson Smith et al.
    Structural analysis of an AKAP18-protein kinase A complex reveals that regions of intrinsic disorder impact the phosphorylation of preferred substrates.

    Dynamic control of adipose tissue development and adult tissue homeostasis by platelet-derived growth factor receptor alpha

    Sunhye Shin et al.
    Combined fate mapping and genetic deletion studies reveal that PDGFRα+ cells and PDGFRα gene itself are required for adipose tissue development but not for adult tissue homeostasis.
