Abstract
BACKGROUND
Many previous studies showed that maternal forced exercise can reduce some central disorders in offsprings, but its clear mechanism remains unclear. In this study, the role of 5-HT2 and D2 receptors in neuroprotective effects of maternal forced exercise in offspring neurodevelopment and effect on some behaviors were evaluated.
MATERIALS AND METHODS
Forty-eight pregnant rats were trained by forced exercise, and some behavioral assays in their offspring were performed in the presence and absence of 5-HT2 and D2 receptor antagonists in various experimental groups.
RESULTS
Our data showed that maternal forced exercise caused increase in latency of pain perception in offsprings in hot plate test, writhing test (WT), and tail flick test. Furthermore, a decrease in intensity was shown by WT. On the other hand, treatment of mothers by forced exercise in combination with 5-HT2 and D2 receptor antagonists could inhibit these effects of forced exercise and cause disturbances in pain perception and intensity.
CONCLUSION
Our data suggested that maternal forced exercise causes protective effects on offspring pain perception and intensity, and in this effect, 5-HT2 and D2 receptors are probably involved.
