Figure 4.
βAPP levels are reduced in Alzheimer's (AD), and dynactin-P50 (DynP50) and βAPP localization is disrupted. Dynactin-P50 (green) and βAPP (red) were detected by immunofluorescence in tissue sections from hippocampus. (A) Total APP intensity is decreased in AD cases. Blue represents DAPI staining of cellular DNA. Images were digitized at 40× magnification. Scale bar = 10 μm. (B) Overall βAPP fluorescence intensity is diminished in AD compared to neurologically normal controls (AMC). Significance determined by Wilcoxon-Mann-Whitney Rank Sum Test, with *denoting p ≤ 0.05. Data reported as group mean with error bars denoting SEM.
