Figure 6.
Neuronal tropism in the dorsal hippocampal DG and CA3 of CG01-treated rat as evidenced by NPY-immunoreactivity being co-expressed with NeuN-immunoreactivity as revealed by fluorescent (A–C) and confocal microscopy (D–F). (A) Fluorescent microscopy overview images of NPY/NeuN co-staining (merge), NPY- and NeuN-immunoreactivity, with high-magnification images of hatched areas in panel (A), showing hilus of the DG (hDG; B) and CA3 (B,C). (D) Confocal microscopy overview image of NPY/NeuN co-staining, with high-magnification images of hatched areas in panel (D), showing co-labeling in fibers and interneuron (white arrow) in hDG (E) and fibers in pyramidal layer of CA3 (pyrCA3; F). Scale bars: 500 μm (A), 100 μm (B–D), and 30 μm (E,F).
