The oligodendrocyte marker, Galactocerebroside (GALC), was localized to vesicles in the MDZ of control brains (Figures 3A2,A1) and AD brains (Figures 3B2,B1), and co-localized with the oxidative stress marker 8-Iso-PGF2α in control (Figures 3A1,A3) and AD brain (Figures 3B1,B3). Here, GALC is linked to Alzheimer disease.
