Fig. 2From: The fluorescent ligand bTVBT2 reveals increased p-tau uptake by retinal microglia in Alzheimer’s disease patients and AppNL−F/NL−F micebTVBT2 co-localization with tau in human hippocampus. Cornu ammonis 1 (CA1) from an AD case stained against tau (A), bTVBT2 (B), and merged image (C), showing little (long arrows) or no (short arrows) co-localization of bTVBT2 with PHF-1-positive NFTs. Hippocampal sections stained with bTVBT2 together with tau (D), p-tau181 (E), AT8 (F), and PHF-1 (G) showing co-localization of bTVBT2 with tau-positive dystrophic neurites. Scale bars in A–C and D–G represent 10 µm and 20 µm, respectivelyBack to article page
