Characterization of the binding sites for 123I-ADAM and the relationship to the serotonin transporter in rat and mouse brains using quantitative autoradiography.

Abstract

This study demonstrates that regional distribution of (123)I-ADAM radioactivity is similar to the SERT localization in both rat and mouse brains. We also validated that destruction on central serotonergic neurons after PCA treatment inhibits the uptake of (123)I-ADAM in serotonin-rich brain regions. High specific binding to SERT in vivo makes (123)I-ADAM an appropriate radiotracer for solitary studies of serotonin functions in living humans.
