Cannabis is the most widely used illicit drug, particularly during adolescence. Its consumption disrupts glutamate homeostasis and synaptic plasticity in the nucleus accumbens (NAc). Here, we identify a functionally distinct accumbal astrocytic ensemble, associated with the ventral hippocampus-NAc (vHip→NAc) circuit, that is critical for tetrahydrocannabinol (THC)-induced synaptic and...

Astrocytes take up glucose from the bloodstream to provide energy to the brain, thereby allowing neuronal activity and behavioural responses1-5. By contrast, astrocytes are under neuronal control through specific neurotransmitter receptors5-7. However, whether the activation of astroglial receptors can directly regulate cellular glucose metabolism to eventually modulate behavioural responses is...

Alterations of long-term synaptic plasticity have been proposed to participate in the development of addiction. To preserve synaptic functions, homeostatic processes must be engaged after exposure to abused drugs. At the mouse cortico-accumbens synapses, a single in vivo injection of Delta9-tetrahydrocannabinol (THC) suppresses endocannabinoid-mediated long-term depression. Using biochemical...

Abstract Cannabis is the most widely used illicit drug, particularly during adolescence, and its consumption disrupts glutamate homeostasis and synaptic plasticity in the nucleus accumbens (NAc). While astrocytic cannabinoid receptors (CB1Rs) are known to modulate synaptic plasticity and behavior, the extent to which specific astrocytic ensembles drive tetrahydrocannabinol (THC)-induced...
