Cocaine inhibits leptin-induced increase of the cocaine- and amphetamine-regulated transcript peptide in the nucleus accumbens in rats.

abstract：:The putative neurotransmitter peptide CART has been suggested to be involved in the actions of psychostimulants. We analyzed the CART mRNA expression in mesolimbic brain areas of male and ovariectomized 17beta-estradiol- (30 microg) and vehicle-treated female rats. A gender difference was noted in the accumbens shell ...
