Contrasting effects of mu opioid receptor and delta opioid receptor deletion upon the behavioral and neurochemical effects of cocaine.

Neuroscience - 1 Jan 2004

Chefer V I, Kieffer B L, Shippenberg T S

Abstract excerpt

Conventional brain microdialysis was used to assess basal and cocaine-induced dopamine (DA) levels in the nucleus accumbens of wildtype (WT) C57BL/6J mice and mice with constitutive deletion of ether mu- or delta-opioid receptors (MOR or DOR knockout [KO], respectively). Locomotor activity was assessed in these same animals. Basal locomotor activity of DOR KO was elevated relative to MOR KO, but did not differ...
