Low dose cromolyn increased plasma Aβ42:Aβ40 ratios. (A,B). MesoScale Aβ-triplex analyses were applied to plasma samples. Differences in Aβ levels (A) and Aβ42:Aβ40 ratios (B) in plasma were analyzed comparing various treatment groups to vehicle. Mean ± SEM; n ≥ 8 (Table 1); *p < 0.05 (vs. vehicle), one-way ANOVA with Dunnett’s multiple comparison test.
