The Endocannabinoid System and the Treatment of Mood and Anxiety Disorders
The central endocannabinoid system is a neuroactive lipid signalling system in the brain which acts to control neurotransmitter release. The expression patterns of this system throughout limbic regions of the brain ideally situate it to exert regulatory control over emotional behaviour, mood and stress responsivity. A growing body of evidence unequivocally demonstrates that deficits in endocannabinoid signalling may result in depressive and anxiogenic behavioural responses, while pharmacological augmentation of endocannabinoid signalling can produce both antidepressive and anxiolytic behavioural responses. The aim of this review is to summarize current knowledge of the role of the endocannabinoid system in the etiology and treatment of mood and anxiety disorders, such as depression, anxiety and post-traumatic stress disorder. Collectively, both clinical and preclinical data argue that cannabinoid receptor signalling may be a realistic target in the development of a novel class of agent for the pharmacotherapy of mood and anxiety disorders.

More about this publication?
- CNS & Neurological Disorders - Drug Targets aims to cover all the latest and outstanding developments on the medicinal chemistry, pharmacology, molecular biology, genomics and biochemistry of contemporary molecular targets involved in neurological and central nervous system (CNS) disorders e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will contain a series of timely in-depth reviews written by leaders in the field covering a range of current topics on drug targets involved in neurological and CNS disorders. As the discovery, identification, characterization and validation of novel human drug targets for neurological and CNS drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
