Semi-quantitative immunomicroscopy for enterocytic abundance of Aβ in control mice. The intensity sums of enterocytic Aβ expressed per nuclei area (A) and representative immunomicrographs showing Aβ (orange) and nuclei (blue) in the intestinal villi (B). The white arrow indicates lamina propria (Lp) and Lu labels the lumen. Data are expressed as mean ± SEM. Statistical significance was estimated by Brown–Forsythe and Welch ANOVA (n = 8–12,*p < 0.05, **p < 0.01, ***p < 0.001).
