Figure 2. Effects of loganin on AD pathology and the expression of Aβ-related key proteins. (A) The relative expression of Aβ deposition. (B, C) The relative expression of APP expression and processing related proteins. (D) The relative expression of Tau phosphorylation. Scale bar = 100 μm. Data were expressed as mean ± SEM, *p < 0.05, ***p < 0.001, n = 3 for each group.
