We studied the role of cocaine and amphetamine related transcript (CART) in regulating context induced reinstatement (renewal) of reward seeking. Rats were trained to respond for alcoholic beer in context A before extinction in context B. Rats were tested for responding in context A (ABA) and context B (ABB). Intracerebroventricular (ICV) infusions of the active fragment CART55-102 but not the inactive fragment CARTI-27 before test prevented ABA renewal of extinguished responding. ICV CART55-102 had no effect on responding in the extinction context (ABB). ICV CART55-102 also altered the profile of behavioral responses observed on test in the training (ABA) but not extinction (ABB) context. These results identify a novel role for CART in preventing reinstatement of reward seeking.
