a A representative dot plot of isolated brain cells from saline or LPS treated mice analyzed by flow cytometry. b Mean ± SD of the percentage of CD11b/CD45^low and CD11b/CD45^high before and 48, 72, and 96 h after LPS treatment and mean ± SD of the fluorescence intensities of CD11b (c). Different literals indicate significant differences between the different groups (p < 0.05) using the Kruskal-Wallis test (non-parametric ANOVA) plus the Dunn’s multiple comparisons test. Data are representative of four experiments
