rAAV vehicles drives gene expression in the medial entorhinal cortex (MEC). Low-magnification view of a horizontal section of mouse brain stained with hoechst ((A) vector; (C) P301L) and GFP autofluorescence showing a restriction of target protein expression in MEC and its projection fibers to the middle molecular layer (mml) of hippocampal dentate gyrus (DG) ((B) vector; (D) P301L, arrows point cell bodies) one month after transduction via rAAV delivery, while no GFP was observed in the granular layer (gl) of the dentate gyrus, which is outlined with a white dotted line (scale bar, 500 μm). The insets in (B,D) show the high magnification of MEC (scale bar, 50 μm). HT-7 was employed to detect human tau in the present study. The results showed a co-localization of HT-7 with GFP in the neuronal cell bodies and fibers of MEC (EG), and the projection fibers to DG region (HJ). (scale bar in (AD) 500 μm; in insets of (B,D) 50 μm; in E-J, 50 μm).
