| Abstract | Background: Regular moderate exercise and endogenous cannabinoid activity have independently been shown to alleviate seizure (SE) attacks. Objectives: This study aimed to investigate the effect of physical activity on the expression levels of cannabinoid CB1 and CB2 receptors in the brains Methods: Male Wistar rats were divided into five groups: Sham, SE, physical activity (PA), PA + SE, and PA before SE. Epileptic SEs were induced by administering pentylenetetrazol (PTZ; intraperitoneally, 35 mg/kg) every other day for four weeks in the SE, PA + SE, and PA before SE groups. Animals in the PA, PA + SE, and PA before SE groups participated in treadmill running (30 minutes per day, five days a week). The mean number of cortical and hippocampal (CA1, CA3) CB1 and CB2 receptors was assessed using immunohistochemistry. Results: The study data revealed a significant reduction of CB1 and CB2 receptors in the CA1, CA3, and cortex of the SE group compared to the sham group. A significant increase in CB1 receptors was observed in the PA and PA before SE groups compared to the SE group in both cortical and hippocampal areas. Physical activity significantly increased hippocampal and cortical CB2 receptor distribution in the PA, PA + SE, and PA before SE groups compared to the SE group. Conclusions: These findings suggest that exercise modulates the expression of hippocampal and cortical cannabinoid receptors in epileptic rats, highlighting the involvement of the endocannabinoid pathway in the anti-epileptic effects of exercise. | en |
