Dopamine Receptors in the Subthalamic Nucleus: Identification and Localization of D5 Receptors
Résumé
Herein we present methodological approaches for the identification and characterization of dopamine receptors in the subthalamic nucleus, a component nucleus of the basal ganglia, at pre-and postsynaptic locations and of their roles with an emphasis given to the dopamine D5 receptor subtype. This chapter focuses on the possible sources of divergence between electrophysiological studies and describes the pharmacological tools available for functional studies of this receptor. The procedures for single-cell reverse transcription PCR (polymerase chain reaction) identification of dopamine D5 receptor mRNA and the immunochemical detection of the receptor at cellular and subcellular levels are presented.
