FIGURE 7.
Knockout of dopamine D3 receptor gene blocked the changes of glutamate NR2B-positive cells in the NAcsh of METH-sensitized mice. (A) Fluorescent staining of the glutamate NR2B in the NAcsh. The red arrows indicated the glutamate NR2B-positive cells. Scale bars = 50 μm. (B,C) Quantification of the number (B) and rate (C) of glutamate NR2B-positive cells in the NAcsh of the four groups of mice (n = 3 mice each). *P < 0.05 compared with the same genotype in saline group; #P < 0.05 compared with same-dose WT mice. Values are presented as mean ±SEM. WT, wild type.
