CD68 and CD11b expression reveal two distinct microglial populations within the DVC of resting animals. A Representative photomicrographs of CD11b and CD68 labeling taken from coronal brainstem sections of resting mice. The white line symbolizes the border between the AP and the NTS. The white boxes indicated regions from panel A where panel B originated. B Insets highlighted the differential expression of CD11b and CD68 of microglial cells located within the AP and funiculus separans/NTS. Scale bars: 500 µm in A; 10 µm in B. AP area postrema; cc central canal; fs funiculus separans; NTS nucleus tractus solitarius
