Roles of astroglial type 1 cannabinoid receptor (CB1) in memory and synaptic plasticity

30/11/2018, 13h30.

Directeur de thèse: Giovanni Marsicano , team leader: “Endocannabinoids and Neuroadaptation” Neurocentre Magendie


The endocannabinoid system is an important modulator of physiological functions. It is composed of cannabinoid receptors,
 their endogenous lipid ligands (the endocannabinoids) and the enzymatic machinery for endocannabinoid synthesis and degradation. The type-1 cannabinoid receptors (CB1) are expressed in different cell types of the brain and are known to be involved in memory processes. Endocannabinoids are mobilized in an activity-dependent manner in brain areas involved in the modulation of memory such as the hippocampus. In this brain region, CB1 receptors are mainly expressed at neuronal pre-synaptic terminals where their stimulation inhibits the release of neurotransmitters, thereby modulating several forms of synaptic activity.
