The CTBN volume Therapeutic Applications of Dopamine D3 Receptor Function reviews the state of the knowledge on the dopamine D3 receptor and its role in human behavior and disease (i.e.: neuropsychiatric illnesses including schizophrenia, mood disorders, Parkinson s disease, restless legs syndrome, addictions and substance use disorders). The volume is written by leading experts across multidisciplinary areas (imaging, biobehavioral testing and clinical trials, preclinical models / molecular pharmacology) converging on the therapeutic implications / potential of the D3 receptor. The D3 dopamine receptor is a member of the D2-like family of G protein-coupled receptors. It was cloned and characterized almost 25 years ago. A key feature of the D3 dopamine receptor system, which has attracted considerable attention, is its anatomical localization remarkably restricted to the limbic circuitry.
