p-tau (AT8) immunohistochemistry. A Negative control—Frontal cortex from autopsy of a patient with no history of dementia; scale bar = 150 µm. B Positive control – Frontal cortex of Alzheimer’s disease patient; scale bar = 150 μm. C Control retina shows no p-tau (AT8) staining; scale bar = 60 μm. D Sections of retina from cases of CTE show no immunoreactivity for p-tau; scale bar = 60 μm
