Figure 1

Confocal photomicrographs showing immunolabeling for CB2 receptors (CB2r), neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) in the ventral tegmental area (VTA) and the nucleus accumbens (NAcc) of wild-type (WT) mice. Double labeling CB2r-NeuN (yellow cells in c) in the VTA and the NAcc and CB2r-GFAP (yellow cells in i) in the VTA indicates the existence of CB2r in neurons and astrocytes.
