    Endocannabinoid dynamics gate spike-timing dependent depression and potentiation

    Yihui Cui et al.
    The molecular mechanisms beyond the bidirectionality (tTLP and tLTD) of endocanabinoid spike-timing dependent synaptic plasticity have been identified.

    Hippocampal inputs engage CCK+ interneurons to mediate endocannabinoid-modulated feed-forward inhibition in the prefrontal cortex

    Xingchen Liu et al.
    Endocannabinoids modulate ventral hippocampal inputs to the infralimbic prefrontal cortex by dampening feed-forward inhibition mediated by cholecystokinin-expressing (CCK+) interneurons onto layer 5 intratelencephalic (IT) cells.

    p21-activated kinase 1 restricts tonic endocannabinoid signaling in the hippocampus

    Shuting Xia et al.
    PAK1 regulates inhibitory synaptic transmission in mice through a cyclooxygenase-2 dependent restriction in tonic, but not phasic, secretion of endocannabinoids.

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

    Loïs S Miraucourt et al.
    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.

    Oxytocin functions as a spatiotemporal filter for excitatory synaptic inputs to VTA dopamine neurons

    Lei Xiao et al.
    Oxytocin, a peptide linked to the processing of socially meaningful stimuli, modulates excitatory synaptic transmission in dopaminergic neurons of ventral tegmental area via retrograde endocannabinoid signaling, acting as a pathway-specific temporal filter for synaptic inputs.

    Cocaine-induced endocannabinoid signaling mediated by sigma-1 receptors and extracellular vesicle secretion

    Yoki Nakamura et al.
    Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.

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

    Adi Drori et al.
    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.

    A chemical proteomic atlas of brain serine hydrolases identifies cell type-specific pathways regulating neuroinflammation

    Andreu Viader et al.
    Cell-specific pathways regulate lipid transmitters and neuroinflammation in the brain.
    1. Neuroscience

    Olfactory connectivity mediates sleep-dependent food choices in humans

    Surabhi Bhutani et al.
    Sleep deprivation enhances energy-dense food choices and encoding of olfactory information in the human brain.

    Cannabinoids modulate associative cerebellar learning via alterations in behavioral state

    Catarina Albergaria et al.
    Cannabinoid receptors modulate cerebellar learning, not through direct effects on synaptic plasticity, but as a secondary consequence of their modulation of behavioral state.
