Pro-inflammatory cytokine levels in the hippocampi of vehicle- or um-PEA-treated mice injected with PTX. (A) Fold expression of mRNA for pro-inflammatory TNF-α; (B) fold expression of mRNA for pro-inflammatory IL-1β; (C) fold expression of mRNA for pro-inflammatory IL-6; (D) fold expression of mRNA for anti-inflammatory IL-10; * p < 0.05, ** p < 0.01, *** p < 0.001 versus vehicle group; ° p < 0.05 versus PTX group. Data are presented as mean ± SEM (n = 8). Differences were evaluated by ANOVA followed by Bonferroni’s post hoc test for multiple comparisons.
