Representative examples of Aβ43 staining in cerebral small vessels. Aβ43-immunostaining was detected in both leptomeningeal (a, b) and parenchymal (d, e) vessels. Some immunostained vessels were partially stained (b, e). In others, Aβ43 staining was detected in the full circumference and thickness of the vessel wall (a, d). Many vessels were devoid of Aβ43 (c). Scale bar = 20 μm (a, b, c, e) or 50 μm (d)
