“Results: The mu-opioid selective agonist DAMGO , tested at doses of 0, 0.05 and 0.5 µg, produced a dose-related reduction in the number of cocaine infusions obtained during the 1-h self-administration sessions.”
“At a dose of cocaine on the ascending limb of the self-administration dose-response curve, DAMGO microinfusions produced an increase in responding for the drug.”
“These experiments suggest that the mu agonist DAMGO is able to shift the dose-response curve for cocaine self-administration to the left.”
“In the nucleus accumbens chronic cocaine led to an increase in both the number of mu-opioid receptors and the maximal inhibition of adenylyl cyclase activity by DAMGO ([D-Ala2,N-methyl-Phe4,Glyol]enkephalin).”
