Abstract

The effects of chronic cocaine use on D₃ receptor mRNA expression in the human nucleus accumbens was assessed by reverse transcription-polymerase chain reaction. D₃ receptor/cyclophilin mRNA ratios in the nucleus accumbens were increased 6-fold in cocaine overdose victims as compared to age-matched and drug-free control subjects. This finding demonstrates that chronic cocaine exposure leads to adaptive increases in the expression of D₃ receptor mRNA in a critical reward center in brain.
