Impaired action of anxiolytic drugs in mice deficient in cannabinoid CB1 receptors
The role of cannabinoid CB(1) receptors in the action of anxiolytics was examined. Deletion of CB(1) receptors resulted in increased anxiety-like behaviours in light/dark box, elevated plus maze andExpand

Decreased Cocaine Motor Sensitization and Self-Administration in Mice Overexpressing Cannabinoid CB2 Receptors
The potential involvement of the cannabinoid CB2 receptors (CB2r) in the adaptive responses induced by cocaine was studied in transgenic mice overexpressing the CB2r (CB2xP) and in wild-type (WT)Expand

Depression‐resistant endophenotype in mice overexpressing cannabinoid CB2 receptors
Background and purpose:  The present study evaluated the role of CB2 receptors in the regulation of depressive‐like behaviours. Transgenic mice overexpressing the CB2 receptor (CB2xP) were challengedExpand

Differential basal proenkephalin gene expression in dorsal striatum and nucleus accumbens, and vulnerability to morphine self-administration in Fischer 344 and Lewis rats
We have previously shown that the acquisition rate of intravenous morphine self-administration under a fixed ratio one (FR1) schedule of reinforcement was greater in Lewis (LEW) than Fischer 344Expand
