Dopamine Receptors Scientific Review
Written by Phillip Strange and revised by Kim Neve in 2013, this review summarizes the history of the dopamine receptors and provides an overview of individual receptor subtype properties, their distribution and identifies ligands which act at each receptor subtype. Compounds available from Tocris are listed.
The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
Major depressive disorder is characterized by depressed mood and a loss of interest and/or pleasure. Updated in 2015 this poster highlights presynaptic and postsynaptic targets for the potential treatment of major depressive disorder, as well as outlining the pharmacology of currently approved antidepressant drugs.
