Cannabidiol has low affinity for the cannabinoid CB1 and CB2 receptors,[26][27] although it can act as an antagonist of CB1/CB2 agonists despite this low affinity.[27] Cannabidiol may be an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[28] It also may act as an inverse agonist of GPR3, GPR6, and GPR12.[29] CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist.[30] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[31] The pharmacological effects of CBD may involve PPARγ agonism and intracellular calcium release.[7]
