Surgery resulted in an increased expression of CB2R in the hippocampus. JWH133 treatment alleviated the surgery-induced upregulation of CB2R in the hippocampus, while AM630 aggravated it. Representative Western blotting bands show the expression of CB2R in the hippocampus 1, 3, and 7 days after surgery (a–c). The expression of CB2R was normalized to that of GAPDH as an internal control (d–f). The data are plotted as the mean ± standard error of the mean for each group (n = 3 per group). *p < 0.05 versus the control group, # p < 0.05 versus the surgery group
