Scientists at The Scripps Research Institute (TSRI) have found evidence that an emotion-related brain region called the central amygdala–whose activity promotes feelings of malaise and unhappiness–plays a major role in sustaining cocaine addiction. In experiments with rats, the TSRI researchers found signs that cocaine-induced changes in this brain system contribute to anxiety-like behavior and other unpleasant symptoms of drug withdrawal–symptoms that typically drive an...

Researchers at The Scripps Research Institute have found new links between a protein that controls our urge to eat and brain cells involved in the development of alcoholism. The discovery points to new possibilities for designing drugs to treat alcoholism and other addictions. The new study, published online ahead of print by the journal Neuropsychopharmacology, focuses on the peptide ghrelin, which is known to stimulate eating. “This is the first study to characterize the effects...

Findings could lead to development of new anti-alcoholism drugs New research by scientists at the Scripps Research Institute has underlined the power of an endogenous anti-stress peptide in the brain to prevent and even reverse some of the cellular effects of acute alcohol and alcohol dependence in animal models. The work could lead to the development of novel drugs to treat alcoholism. The new study, led by Scripps Research Associate Professor Marisa Roberto and now published online...

Finding could lead to development of drugs that decrease heavy alcohol consumption A team of Scripps Research Institute scientists has found a key biological mechanism underpinning the transition to alcohol dependence. This finding opens the door to the development of drugs to manage excessive alcohol consumption. "Our focus in this study, like much of our lab's research, was to examine the role of the brain's stress system in compulsive alcohol drinking driven by the aversive aspects of...

The new research suggests potential target for drugs to combat alcohol addiction In findings that should finally put to rest a decade of controversy in the field of neurobiology, a team at The Scripps Research Institute has found decisive evidence that a specific neurotransmitter system"”the endocannabinoid system"”is active in a brain region known to play a key role in the processing of memory, emotional reactions, and addiction formation. The new study also shows that this...

The findings suggest development of drug treatment for substance abuse A team of scientists from The Scripps Research Institute has found that a specific stress hormone, the corticotropin-releasing factor (CRF), is key to the development and maintenance of alcohol dependence in animal models. Chemically blocking the stress factor also blocked the signs and symptoms of addiction, suggesting a potentially promising area for future drug development. The article, the culmination of more than six...
