Figure 6. Rapamycin reduced the number of activated microglia.
(A–C) Representative sections from CA1/subiculum regions of brains from 3xTg-ADCTL, 3xTg-AD15–18 and 3xTg-AD2–18 mice brains (n = 8/group) immunostained with an anti-CD45 antibody. (D) Semi-quantitative analysis showed that the number of activated microglia was significantly different across the three groups as determined by one-way ANOVA (F = 5.7; p = 0.01). Bonferroni's post hoc analysis showed that the number of activated microglia was significantly lower in the 3xTg-AD2–18 mice compared to the other two groups. No statistically significant changes were found between 3xTg-ADCTL and 3xTg-AD15–18 mice. Data are presented as means ± SEM.
