Development of novel treatments for drug addiction.
Current Research Focus
Drug addiction is a chronic disorder that is characterized by compulsive drug taking and relapse after periods of abstinence. The research in our laboratory focuses on the development of non-addictive treatments for nicotine, alcohol, and opioid addiction. We use animal models to study the neuronal substrates that mediate the negative mood state and anxiety-like behavior associated with drug withdrawal. The negative mood state associated with drug withdrawal is investigated with the intracranial self-stimulation procedure and anxiety-like behavior is investigated with the elevated plus maze test and other anxiety tests. In addition, we study drug self-administration and stress, drug, and cue-induced reinstatement of extinguished drug seeking behavior. Our research group has shown that corticotropin-releasing factor (CRF) mediates the negative mood state associated with nicotine and alcohol withdrawal and plays a critical role in stress-induced relapse of extinguished nicotine-seeking behavior. These studies may lead to the development of treatments that decrease drug abuse in humans and prevent relapse after a period of abstinence.
