Fig. 3From: 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 AT8 and PHF-1 but not p-tau181 in human retina. Confocal image of the orthogonal view of a flat-mount retina sample from an AD stained against p-tau181 (A) (purple indicated with an arrow), PHF-1 (B) (purple indicated with arrow), and AT8 (C) (purple) together with bTVBT2 (red in A–C) and Iba-1 (green in A–C). The three p-tau stainings are merged with a staining against DAPI (purple, red, green, and blue in A–C). Scale bars in (A–C), represent 5 µmBack to article page
