Metabotropic Glutamate Receptors Scientific Review
Written by Francine Acher, this review discusses the pharmacology and therapeutic potential of mGlu receptors, and the compounds acting upon them; compounds available from Tocris are listed.
Addiction Poster
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.
Depression Poster
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.
Huntington's Disease Poster
Huntington's disease (HD) is a severe monogenic neurodegenerative disorder, which is characterized by the prevalent loss of GABAergic medium spiny neurons (MSN) in the striatum. This poster summarizes the effects of mutant huntingtin aggregation implicated in the pathology of HD, as well as highlighting the use of iPSCs for HD modeling.
Parkinson's Disease Poster
Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.
