Activity of SOD1. SOD1 activity was assessed in untreated microglia (open bar), in LPS-treated cells (solid bar), and in cells treated for 20 h with 5% (v/v) CFS from each bacterial strain (Lp10, green bars; Lr13, blue bars; Lhr19, pink bars) in the presence of absence of 1 µg/mL LPS (LPS + CFS). Results expressed in U/mL represent the mean ± SD from three independent experiments. Statistically significant differences were assessed by one-way ANOVA followed by Tukey’s post hoc test. *p < 0.05; **p < 0.01
