A 'James Bond' drug which would enable a spy to drink his opponent under the table, without getting drunk himself may soon become a reality!

Scientists have produced mutant worms that do not get intoxicated by alcohol, an advance that could lead to new drugs to treat alcohol addiction.

Researchers at the University of Texas at Austin generated mutant worms by inserting a modified human alcohol target into the worms.

"This is the first example of altering a human alcohol target to prevent intoxication in an animal," said corresponding author, Jon Pierce-Shimomura, assistant professor in the university's College of Natural Sciences and Waggoner Center for Alcohol and Addiction Research.

An alcohol target is any neuronal molecule that binds alcohol, of which there are many.

One important aspect of this modified alcohol target, a neuronal channel called the BK channel, is that the mutation only affects its response to alcohol.

The BK channel typically regulates many important functions including activity of neurons, blood vessels, the respiratory tract and bladder. The alcohol-insensitive mutation does not disrupt these functions at all.

"We got pretty lucky and found a way to make the channel insensitive to alcohol without affecting its normal function," said Pierce-Shimomura.

"Our findings provide exciting evidence that future pharmaceuticals might aim at this portion of the alcohol target to prevent problems in alcohol abuse disorders," said Pierce-Shimomura.

"However, it remains to be seen which aspects of these disorders would benefit," he said.

Unlike drugs such as cocaine, which have a specific target in the nervous system, the effects of alcohol on the body are complex and have many targets across the brain.

The various other aspects of alcohol addiction, such as tolerance, craving and the symptoms of withdrawal, may be influenced by different alcohol targets.

The worms used in the study, Caenorhabditis elegans, model intoxication well. Alcohol causes the worms to slow their crawling with less wriggling from side to side.

The intoxicated worms also stop laying eggs, which build up in their bodies and can be easily counted.

The modified human BK channel used in the study, which is based on a mutation discovered by lead author and graduate student Scott Davis, could be inserted into mice.

These modified mice would allow scientists to investigate whether this particular alcohol target also affects tolerance, craving and other symptoms relevant to humans.

Scientists speculate that their research could even be used to
