Localization of the mRNA for the 5-HT2 receptor by in situ hybridization histochemistry. Correlation with the distribution of receptor sites
Abstract
32P-labelled oligonucleotides complementary to rat 5-HT2 receptor mRNA were used as probes to study the distribution of cells in rat brain containing the mRNA coding for this receptor by in situ hybridization histochemistry. 5-HT2 receptor binding sites were visualized by autoradiography using [125I]DOI as ligand. Both distributions were comparable, demonstrating that 5-HT2 receptors are expressed by cells intrinsic to the neocortex (lamina Va), claustrum, olfactory bulb and several nuclei of the brainstem.
