5-HT Receptors Scientific Review
Written by Nicholas M. Barnes and John F. Neumaier, this review summarizes the various serotonin receptor subtypes and their importance in mediating the role of serotonin in numerous physiological and pharmacological processes. Compounds available from Tocris are listed.
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.
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.
