Abstract

The presence, pharmacological properties and anatomical distribution of serotonin-1C and serotonin-2 receptor subtypes were studied in the human brain by both radioligand binding and autoradiographic procedures. Frontal cortex, hippocampus and choroid plexus from human brains obtained at autopsy without history of neurological diseases were used in this study. [3H]5-HT and [3H]mesulergine were used to label 5-HT1C recognition sites while [3H]ketanserin was used to label 5-HT2 receptors. The pharmacological profile of 5-HT1C sites which are very concentrated in the choroid plexus, was extremely similar to that of pig and rat 5-HT1C sites. These receptors were also detected in the hippocampus ..
