Cyclic AMP 30-34 cannabinoid receptor 1 Homo sapiens 0-3 28445587-3 2017 Adopting a combined pharmacological and genetic approach to study the molecular mechanisms of CB1R-induced silencing, we found that adenylyl cyclase inhibition decreases cAMP levels while it increases the number of silent synaptic boutons and occludes the induction of further silencing by the cannabinoid agonist HU-210. Cyclic AMP 170-174 cannabinoid receptor 1 Homo sapiens 94-98
