Immunohistochemical staining of VGluT3, EAAT2 and EAAT3 in the rat CB. Immunohistochemical staining showing the location of VGluT3 (A1–2), EAAT2 (B1–2) and EAAT3 (C1–2) in rat CB. D1-D2 are negative staining control obtained by omitting the primary antibody. A2-D2 are higher magnifications images of rectangle areas in A1-D1, respectively. The brown staining represents the glutamate transporter, while the blue staining represents hematoxylin-stained cell nuclei. VGluT: vesicular glutamate transporter; EAAT: excitatory amino acid transporter. Scale Bar = 50 μm for all images
