Staining using PBB5 and anti-phosphorylated tau antibody (AT-8) in the caudate/putamen from patients with CBD and motor cortex from PSP showed an overlapping signal, which indicates that PBB5 is capable of recognizing AT-8-positive coiled bodies (Figs. 1, h, i) and argyrophilic threads in oligodendrocytes (SFigs. 2a,b), and tufted astrocyte (SFig. 2c). This evidence concerns the gene MAPT and red-green color blindness.
