3R- and 4R-tau-positive Inclusions in PPA due to Alzheimer’s Disease. 3R-positive pathology visualized through RD3 immunohistochemical staining in granule (a) and hilar cells (c); taken from case PPA-AD 7. 4R-positive pathology visualized through ET3 immunohistochemical staining in granule (b) and hilar cells (d); taken from case PPA-AD 5. Ratio of stereologic densities revealed ~ 1:1 ratio of 3R-to-4R immunopositivity in the granule cells, and ~ 1.5:1 ratio in hilar cells. Differences in 3R and 4R densities were not significantly different. Scale bar = 50 µm in d, and applies to a–c
