    Spatial tuning and brain state account for dorsal hippocampal CA1 activity in a non-spatial learning task

    Kevin Q Shan, Evgueniy V Lubenov ... Athanassios G Siapas
    Recordings in freely-moving rats show that hippocampal dorsal CA1 pyramidal cells signal only spatial information, even in a non-spatial task such as trace eyeblink conditioning.

    Pregnancy success in mice requires appropriate cannabinoid receptor signaling for primary decidua formation

    Yingju Li, Amanda Dewar ... Xiaofei Sun
    Cannabinoid signaling is critical for integration of vascular system and uterine decidualization.

    CB1R regulates soluble leptin receptor levels via CHOP, contributing to hepatic leptin resistance

    Adi Drori, Asaad Gammal ... Joseph Tam
    The hepatic endocannabinoid/CB1R system controls the soluble leptin receptor’s expression and/or subsequent release by Trib3-induced regulation of C/EBP homologous protein levels in hepatocytes to affect leptin signaling in the liver.

    Endocannabinoid signaling enhances visual responses through modulation of intracellular chloride levels in retinal ganglion cells

    Loïs S Miraucourt, Jennifer Tsui ... Edward S Ruthazer
    Endocannabinoid activation of the CB1 receptor on retinal ganglion cells in the eye results in enhanced excitability and responsiveness to visual stimulation through a novel mechanism involving intracellular chloride regulation.

    A Bayesian approach to dynamic homology of morphological characters and the ancestral phenotype of jawed vertebrates

    Benedict King, Martin Rücklin
    The ancestor of all known jawed vertebrates possessed a maxilla and premaxilla and was similar in morphology to the 'maxillate placoderms' from China.

    The C-terminal helix 9 motif in rat cannabinoid receptor type 1 regulates axonal trafficking and surface expression

    Alexandra Fletcher-Jones, Keri L Hildick ... Jeremy M Henley
    An intracellular H9 motif facilitates the highly localised axonal surface expression of CB1R.

    Experience-dependent shaping of hippocampal CA1 intracellular activity in novel and familiar environments

    Jeremy D Cohen, Mark Bolstad, Albert K Lee
    Comparison of the intracellular activity of hippocampal neurons in novel and familiar environments reveals experience-dependent changes in inputs underlying the formation of stable representations of space.

    Inhibitory CCK+ basket synapse defects in mouse models of dystroglycanopathy

    Jennifer N Jahncke, Daniel S Miller ... Kevin M Wright
    Loss of functional dystroglycan disrupts the formation and function of CCK+/CB1R+ inhibitory synapses in hippocampal CA1, resulting in reduced seizure thresholds in mouse models of dystroglycanopathy.

    CM1-driven assembly and activation of yeast γ-tubulin small complex underlies microtubule nucleation

    Axel F Brilot, Andrew S Lyon ... David A Agard
    Cryo-EM structures reveal that the conserved CM1 motif drives γTuRC assembly by bridging adjacent γTuSC.

    Cannabinoid signaling modulation through JZL184 restores key phenotypes of a mouse model for Williams–Beuren syndrome

    Alba Navarro-Romero, Lorena Galera-López ... Andres Ozaita
    A mouse model of Williams–Beuren syndrome allowed us to assess the endocannabinoid system and the impact of targeting the monoacyl glycerol lipase in modulating key phenotypes such as cognitive and hypersocial phenotype as well as the cardiac phenotype.
