title: [The role of dopamine D3 receptor in the amphetamine-induced conditioned place preference in mice].
abstract: OBJECTIVE
  To study the role of dopamine D3 receptor involved in the amphetamine-induced conditioned place preference (CPP) in mice.
  
  
  METHODS
  The CPP was observed in D3 receptor knock-out (D3RKO) mice and C57BL/6 wild-type control mice after administration of amphetamine. The data were analyzed with a two-way ANOVA using the SPSS 13.0 software.
  
  
  RESULTS
  D3RKO mice showed a significant amphetamine-induced CPP (P<0.001), compared with the ones administered with saline in C57BL/6 control mice.
  
  
  CONCLUSIONS
  The results indicate that amphetamine can produce significant CPP in dopamine D3 receptor knock-out mice, suggesting that amphetamine-induced addiction can be inhibited by dopamine D3 receptor.
