摘要	Aspirin (ASP) is the most commonly used non-steroidal anti-inflammatory drug in the world. Recent clinical and preclinical evidence suggests that ASP may also exert psychoactive effects. It remains unclear whether ASP has antidepressant-like activity, and any molecular mechanisms underlying such activity have yet to be elucidated. Using the forced swimming test (FST), a well-established animal model of depression widely used to screen potential antidepressants in rodents, we investigated the effects of subacute treatment with ASP (0, 6, 12, 25, and 50 mg/kg, i.p.) on immobility in the FST, and on FST-induced changes in endocrine and immune parameters in rats, in comparison to the clinical antidepressants imipramine (IMI) and fluoxetine (FLU). Serum levels of corticosterone, pro-inflammatory cytokine interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) were determined by enzyme-linked immunosorbent assay. ASP dose-dependently decreased immobility in the FST, without altering the locomotor activity in the open-field test. The inhibitory effects of higher doses (25 and 50 mg/kg) of ASP on immobility were similar to that of FLU and IMI at a dose of 10 mg/kg. In addition, the levels of corticosterone, IL-6, and TNF-alpha in peripheral blood were significantly increased after the FST exposure. IMI, but not FLU and ASP at any dose tested, significantly attenuated corticosterone responses in the FST. Both FLU and IMI treatment reduced the increase of IL-6 and TNF-a levels following the FST exposure. ASP dose-dependently decreased FST-induced increase of cytokine levels, as manifested by significantly stronger effects on IL-6 and TNF-alpha levels at higher doses (25 and 50 mg/kg) than the lowest dose of ASP (6 mg/kg). In all, these results indicate that ASP treatment dose-dependently decreased the immobility time and the release of pro-inflammatory cytokines in the FST suggesting that the anti-inflammatory effects of ASP might be involved in the antidepressant-like effect.
