Figure Lengend Snippet: D4R-immunoreactivity in astrocytes. (A,B) Moderate D4R-immunoreactivities of the cortical surface of the prelimbic (A) and somatosensory (B) areas. (C,D) Confocal imaging of double immunostaining for D4R (magenta) and GS (green) indicated strong D4R-immunoreactivities in pial astrocytes (arrowheads) in the prelimbic area. (E,F) Confocal imaging of double immunostaining for D4R (magenta) and GS (green) indicated strong D4R-immunoreactivities in pial astrocytes (arrowheads) in the primary motor area. (G,H) In layer I of the primary motor area, astrocytes showed strong immunoreactivities for D4R (arrows). (I,J) In layer V, weak D4R-immunoreactivities were observed in protoplasmic astrocytes (arrows). (K,L) In layer II of the somatosensory area, D4R-immunoreactivities were observed in GS-negative cells (asterisks). (M,N) In layer V of the primary motor area, D4R-immunoreactivities were observed in a pyramidal cell-like large cell (asterisks) and its process (arrows). (O–R) In layer I of the primary motor area, strong and granular immunoreactivities for D4R were observed (arrowheads), which were in close vicinity of the GS-positive structure (green), but not overlapped. Nuclei were stained with Hoechst33342. Scale bars: 20 μm (A,B) ; 10 μm; (C,D,I–N) ; 5 μm (E–H) ; 2 μm (O–R) .
