Figure 7. Reduction in microglial activity in cortices of FTY720-treated Hexb−/− mice at 15 weeks.

Figure 7

FTY720 was orally administered to Hexb+/− or Hexb−/− mice at 3–15 weeks of age. (A) Immunostaining of coronal sections for CD68 (green) and Iba1 (red) in the cerebral cortices of control and FTY720-treated Hexb−/− mice at 15 weeks. Blue represents DAPI staining. Insets (a–d) show magnified views of the boxed regions. Scale bar, 100 μm. (B,C) Quantitative analysis of the number of CD68+ (B) and Iba1+ (C) cell immune signals in the cerebral cortices of control Hexb+/−, FTY720-treated Hexb+/−, control Hexb−/−, and FTY720-treated Hexb−/− mice at 15 weeks. Boxes, 25th–75th percentile with the median indicated; bars, 10th and 90th percentiles. Analyzed using a Kruskal–Wallis test (non-parametric ANOVA) followed by a Dunn’s post hoc test (n = 6). *P < 0.05.
