However, tau seeding and propagation in neurons, astrocytes and oligodendrocytes was observed following inoculation of paired helical filament (PHF)-enriched fractions from CBD and PSP; deposits in astrocytes comparable to astrocytic plaques were reported following inoculation of CBD, and doubtful tufted astrocytes following inoculation of PSP homogenates (Narasimhan et al., 2017). Here, MAPT is linked to red-green color blindness.
