The 5-hydroxytryptamine(6) (5-ht(6)) was one of the most recent additions to the 5-HT receptor family, selective antagonists have recently been developed and potential functional roles are now becoming apparent. The high affinity of a wide range of psychiatric drugs for the 5-ht(6)receptor, together with its almost exclusive expression in the CNS, being abundant in limbic and cortical regions, has stimulated significant research interest. The 5-ht(6)receptor appears to regulate glutamatergic and cholinergic neuronal activity, and increasing evidence suggests that it may be involved in the regulation of cognition, feeding and, possibly, affective state and seizures. The current article will review all aspects of the discovery, genetics, distribution, pharmacology and function of the 5-ht(6)receptor. Taken together, this wealth of information warrants the use of the upper case nomenclature for the 5-ht(6) receptor to be approved and its true status recognised.
