摘要
In view of the co-localization of spinal delta- and kappa-opioid receptors, we have investigated the interaction of selective opioid receptor agonists and antagonists in the spinal cord of mice in order to determine if these receptors are organized as heteromers. The finding that norbinaltorphimine (kappa) antagonized [D-Pen(2,5)]enkephalin (delta(1)), but not deltorphin II (delta(2)), strongly suggests that the putative delta(1)-subtype is a delta-kappa heteromer. Studies with selective opioid receptor (ant)agonists support this conclusion. (C) 2003 Elsevier Science B.V. All rights reserved.
