Fig. 5: GAT-1 and GAT-3 are expressed on plasma membranes of striatal astrocytes.

a Striatal immunofluorescence signals for astrocyte marker S100β (magenta) in dorsolateral striatum (DLS) and nucleus accumbens core (NAcC). Scale bars: 100 µm, for inset: 10 µm. cc corpus callosum, ac anterior commissure. b Immunofluorescence signals for S100β do not colocalize with immunofluorescence signals for neuronal marker NeuN. Scale bars: 10 µm. c, d GAT-1 (cyan, c) and GAT-3 (green, d) and are expressed on plasma membranes of striatal S100β-expressing astrocytes imaged in DLS. Immunoreactivity for left, S100β, centre, GAT, right, merged. Scale bars: 5 μm.
