چکیده انگلیسی
Opioid and glutamatergic receptors have a key role in depression following stress. In this study, we assessed opioid and glutamatergic receptors interaction with the depressant-like behavior of acute foot-shock stress in the mouse forced swimming test. Stress was induced by intermittent foot shock stimulation during 30 min and swim periods were afterwards conducted by placing mice in separated glass cylinders filled with water for 6 min. The immobility time during the last 4 min of the test was considered. Acute foot-shock stress significantly increased the immobility time of mice compared to non-stressed control group (Pâ¤0.01). Administration of non-selective opioid receptors antagonist, naltrexone (1 and 2 mg/kg, i.p.), and the selective non-competitive NMDA receptor antagonist, MK-801 (0.05 mg/kg, i.p.), and the selective serotonin reuptake inhibitor, fluoxetine (5 mg/kg), significantly reduced the immobility time in stressed animals (Pâ¤0.01). Lower doses of MK-801 (0.01 mg/kg), naltrexone (0.3 mg/kg), NMDA (75 mg/kg) and morphine(5 mg/kg) had no effect on foot-shock stressed mice. Combined treatment of sub-effective doses of naltrexone and MK-801 significantly showed an antidepressant-like effect (Pâ¤0.001). On the other hand, co-administration of non-effective doses of NMDA and morphine with effective doses of naltrexone and MK-801 reversed the anti-immobility effect of these drugs. Taken together, we have for the first time demonstrated the possible role of opioid/NMDA receptors signaling in the depressant-like effect of foot-shock stress, and proposed the use of drugs that act like standard anti-depressants in stress-induced depression.
