Abstract
Bidirectional communication between neurons and astrocytes shapes synaptic plasticity and behavior. D-serine is a necessary co-agonist of synaptic N-methyl-D-aspartate receptors (NMDARs), but the physiological factors regulating its impact on memory processes are scantly known. We show that astroglial CB1 receptors are key determinants of object recognition memory by determining the availability of D-serine at hippocampal synapses. Mutant mice lacking CB1 receptors from astroglial cells (GFAP-CB1-KO) displayed impaired object recognition memory and decreased in vivo and in vitro long-term potentiation (LTP) at CA3-CA1 hippocampal synapses. Activation of CB1 receptors increased intracellular astroglial Ca2+ levels and extracellular levels of D-serine in hippocampal slices. Accordingly, GFAP-CB1-KO displayed lower occupancy of the co-agonist binding site of synaptic hippocampal NMDARs. Finally, elevation of D-serine levels fully rescued LTP and memory impairments of GFAP-CB1-KO mice. These data reveal a novel mechanism of in vivo astroglial control of memory and synaptic plasticity via the D-serine-dependent control of NMDARs.

Abstract
The type-1-cannabinoid (CB1 ) receptor is amongst the most widely expressed G protein-coupled receptors in the brain. In few decades, CB1 receptors have been shown to regulate a large array of functions from brain cell development and survival to complex cognitive processes. Understanding the cellular mechanisms underlying these functions of CB1 is complex due to the heterogeneity of the brain cell types on which the receptor is expressed. Although the large majority of CB1 receptors act on neurons, early studies pointed to a direct control of CB1 receptors over astroglial functions including brain energy supply and neuroprotection. In line with the growing concept of the tripartite synapse highlighting astrocytes as direct players in synaptic plasticity, astroglial CB1 receptor signaling recently emerged as the mediator of several forms of synaptic plasticity associated to important cognitive functions. Here, we shortly review the current knowledge on CB1 receptor-mediated astroglial functions. This functional spectrum is large and most of the mechanisms by which CB1 receptors control astrocytes, as well as their consequences in vivo, are still unknown, requiring innovative approaches to improve this new cannabinoid research field.

Abstract
Type-1 cannabinoid (CB1) and leptin (ObR) receptors regulate metabolic and astroglial functions, but the potential links between the two systems in astrocytes were not investigated so far. Genetic and pharmacological manipulations of CB1 receptor expression and activity in cultured cortical and hypothalamic astrocytes demonstrated that cannabinoid signaling controls the levels of ObR expression. Lack of CB1 receptors also markedly impaired leptin-mediated activation of signal transducers and activators of transcription 3 and 5 (STAT3 and STAT5) in astrocytes. In particular, CB1 deletion determined a basal overactivation of STAT5, thereby leading to the downregulation of ObR expression, and leptin failed to regulate STAT5-dependent glycogen storage in the absence of CB1 receptors. These results show that CB1 receptors directly interfere with leptin signaling and its ability to regulate glycogen storage, thereby representing a novel mechanism linking endocannabinoid and leptin signaling in the regulation of brain energy storage and neuronal functions.

Abstract
Impairment of working memory is one of the most important deleterious effects of marijuana intoxication in humans, but its underlying mechanisms are presently unknown. Here, we demonstrate that the impairment of spatial working memory (SWM) and in vivo long-term depression (LTD) of synaptic strength at hippocampal CA3-CA1 synapses, induced by an acute exposure of exogenous cannabinoids, is fully abolished in conditional mutant mice lacking type-1 cannabinoid receptors (CB(1)R) in brain astroglial cells but is conserved in mice lacking CB(1)R in glutamatergic or GABAergic neurons. Blockade of neuronal glutamate N-methyl-D-aspartate receptors (NMDAR) and of synaptic trafficking of glutamate α-amino-3-hydroxy-5-methyl-isoxazole propionic acid receptors (AMPAR) also abolishes cannabinoid effects on SWM and LTD induction and expression. We conclude that the impairment of working memory by marijuana and cannabinoids is due to the activation of astroglial CB(1)R and is associated with astroglia-dependent hippocampal LTD in vivo.

Abstract
This study has investigated the role of hypothalamic and amygdalar type-1 cannabinoid (CB1) receptors in the emotional and neuroendocrine responses to stress. To do so, we used the Cre/loxP system to generate conditional mutant mice lacking the CB1 gene in neurons expressing the transcription factor single-minded 1 (Sim1). This choice was dictated by former evidence for Sim1-Cre transgenic mice bearing Cre activity in all areas expressing Sim1, which chiefly includes the hypothalamus (especially the paraventricular nucleus, the supraoptic nucleus, and the posterior hypothalamus) and the mediobasal amygdala. Genomic DNA analyses in Sim1-CB1(-/-) mice indicated that the CB1 allele was excised from the hypothalamus and the amygdala, but not from the cortex, the striatum, the thalamus, the nucleus accumbens, the brainstem, the hippocampus, the pituitary gland, and the spinal cord. Double-fluorescent in situ hybridization experiments further indicated that Sim1-CB1(-/-) mice displayed a weaker CB1 receptor mRNA expression in the paraventricular nucleus of the hypothalamus and the mediobasal part of the amygdala, compared to wild-type animals. Individually housed Sim1-CB1(-/-) mice and their Sim1-CB1(+/+) littermates were exposed to anxiety and fear memory tests under basal conditions as well as after acute/repeated social stress. A principal component analysis of the behaviors of Sim1-CB1(-/-) and Sim1-CB1(+/+) mice in anxiety tests (open field, elevated plus-maze, and light/dark box) revealed that CB1 receptors from Sim1-expressing neurons exert tonic, albeit opposite, controls of locomotor and anxiety reactivity to novel environments. No difference between genotypes was observed during the recall of contextual fear conditioning or during active avoidance learning. Sim1-CB1(-/-), but not Sim1-CB1(+/+), mice proved sensitive to an acute social stress as this procedure reverted the increased ambulation in the center of the open field. The stimulatory influence of repeated social stress on body and adrenal weights, water intake, and sucrose preference was similar in the two genotypes. On the other hand, repeated social stress abolished the decrease in cued-fear conditioned expression that was observed in Sim1-CB1(-/-) mice, compared to Sim1-CB1(+/+) mice. This study suggests that CB1 receptors located on Sim1-expressing neurons exert a tonic control on locomotor reactivity, unconditioned anxiety, and cued-fear expression under basal conditions as well as after acute or repeated stress.
