1 Additionally, reported evidence indicates that the mu-opioid receptor (MOR) interacts with the 5-HT1A-R in the dPAG. dpag opioid receptor mu 1 Homo sapiens
2 Additionally, reported evidence indicates that the mu-opioid receptor (MOR) interacts with the 5-HT1A-R in the dPAG. dpag opioid receptor mu 1 Homo sapiens
3 In the present work, pretreatment of the dPAG with the selective MOR blocker CTOP antagonized the anti-escape effect of chronic fluoxetine (10 mg/kg, i.p., daily, for 21 days), as measured in the elevated T-maze (ETM) test, indicating mediation of this effect by the MOR. dpag opioid receptor mu 1 Homo sapiens
4 In the present work, pretreatment of the dPAG with the selective MOR blocker CTOP antagonized the anti-escape effect of chronic fluoxetine (10 mg/kg, i.p., daily, for 21 days), as measured in the elevated T-maze (ETM) test, indicating mediation of this effect by the MOR. dpag opioid receptor mu 1 Homo sapiens
5 In addition, the combined administration of sub-effective doses of the selective MOR agonist DAMGO (intra-dPAG) and sub-effective doses of chronic as well as subchronic (7 days) fluoxetine increased avoidance and escape latencies, suggesting that the activation of MORs may facilitate and accelerate the effects of fluoxetine. dpag opioid receptor mu 1 Homo sapiens
