Figure 1.
illustrates representative CAA localization by the APOE genotypes. (A) shows a subject with ε3/3 genotype with sparse CAA which is confined to segmental deposition of β amyloid in only meningeal vessels, and the cortex has few β amyloid plaques. (B) shows a ε2 carrier with CAA present in meningeal and intracerebral cortical vessels, as well as few β amyloid plaques in the cortex. (C) shows a ε4 carrier with marked CAA in meningeal and intracerebral cortical vessels, as well as frequent β amyloid plaques in the cortex. Scale bar = 150 μm.
