Figure 5.
Blood–brain barrier integrity of THY-Tau22 mice. Immunofluorescence labelling of the tight junction marker zonula occludens-1 (ZO-1; red) and the constitutive endothelial marker von Willebrand factor (VWF; green) in the CA1 region of the hippocampus of wild-type (WT; top) and THY-Tau22 mice (bottom) at 12 months of age. DAPI staining of nuclei in blue. Similar co-stainings was observed in both genotypes, reflecting an absence of major blood–brain barrier impairment in transgenic animals. n = 3/group. Scale bar = 20 µm.
