Chronic effects of β-FNA on LPS-induced elevations of CCL2 in male C57BL/J6 mice. Micro-osmotic pumps containing saline or β-FNA (42 μg/d) were surgically implanted and dispensed at a flow rate of 0.5 μL/h for 7d. 6d post-surgery, mice (n = 7–8/group) were injected (i.p.) with either 25 μL saline control or LPS (0.83 mg/kg). Behavioral tests were administered 24 h later, and termination followed immediately after. CCL2 was measured via ELISA in (A) frontal cortex, (B) hippocampus, and (C) spleen tissues. Data are presented as mean ± SEM. A Two-ANOVA (n = 5–7/group) indicated that there was no significant main effect for LPS (p = 0.33) or β-FNA (p = 0.11) on CCL2 levels in the frontal cortex, but there was a significant interaction of main effects (p < 0.0001). B Two-way ANOVA revealed a significant main effect of LPS (p < 0.005), no significant main effect of β-FNA (p = 0.55), and a significant interaction of main effects (p < 0.005) on CCL2 levels in the hippocampus (n = 6–7/group). C Two-way ANOVA (n = 5–8/group) suggested a main effect for LPS (p < 0.0001) and β-FNA (p < 0.0001) on CCL2 levels in the spleen, but no interaction of main effects (p = 0.24). Pairwise comparisons were assessed using Fisher's LSD test; bars with letters in common indicate data are not significantly different (p > 0.05)
