Patricia Schonhofen, Ivi Juliana Bristot, José Alexandre Crippa, Jaime Eduardo Cecilio Hallak, Antonio Waldo Zuardi, Richard B. Parsons, Fabio Klamt CNS Drugs, 2018, 32 (Suppl 1), 1-16 https///doi.org/10.1007/s40263-018-0550-4 Abstract : The endocannabinoid retrograde signaling pathway is widely expressed in the central nervous system, where it plays major roles in regulating synaptic plasticity (excitatory and inhibitory) through long-term potentiation and long-term depression. The endocannabinoid system (ECS) components-cannabinoid receptors, endocannabinoids and synthesis/degradation enzymes-are expressed and are functional from early developmental stages and throughout adolescent cortical development, regulating progenitor cell fate, neural [...]
