"It do appear that everywhere you see supersensitivity, you see high-affinity dopamine D2 receptors as the predominant form," said Grandy, a pioneer in the study of the dopamine neurotransmitter system. "But to utter you're going to after reverse supersensitivity by path of shifting the D2-high prestige, we haven't done that. To make that, we must be competent to selectively knead the system in such a way that we could drive the receptor from high-to low-affinity or otherwise effect its flair to motion trimly by some drug treatment." While supersensitivity is lone ruthless by notice behavioral change, and the high-affinity D2 is verified pharmacologically, "what we're showing is a highly undeniable correlation between the being there of a high profit of high-affinity D2 in a population of receptors in animals that make obvious supersensitivity to dopaminergic drugs," Grandy added.
