5-Hydroxytryptamine (5-HT, serotonin) is an indolealkylamine that is found in multiple tissues of vertebrates and invertebrates. This chapter reviews the biochemistry, pharmacology, and physiology of 5-HT receptors. Each receptor subtype has a unique distribution. 5-HTIA receptors are located most densely in the limbic system, 5-HTIB in the striatum, 5-HTIC in the choroid plexus, 5-HT2 in the neocortex, and 5-HT3 in the area postrema. A consistently observed effect of 5-HTIA activation has been the modulation of adenylate cyclase activity. Both increases in basal cyclase and the inhibition of forskolin-stimulated cyclase activity have been reported. These discrepancies may have resulted from tissues that had more than one type of closely related 5-HT receptor. This problem has been surmounted by using mammalian cell lines that have no 5-HT receptors and transfecting them with the 5-HTIA gene.
