Alcohol addiction ruins millions of lives every year, but scientists may have found a cure for this terrible affliction. A new treatment for alcohol use disorder (AUD) has been trialled in monkeys with impressive results and, if these translate to human trials, the impact could be monumental. A team of neuroscientists and physiologists from across the US tested a new type of gene therapy to see if they could directly target the underlying brain circuitry associated with sustained heavy drinking. As they noted, in the journal Nature Medicine, people suffering from AUD commonly return to alcohol use even if they attempt to quit. This is largely to do with what’s known as mesolimbic dopamine (DA) signalling – meaning how the central nervous system circuit communicates the feelgood neurotransmitter dopamine. A protein called glial-derived neurotrophic factor (GDNF) is key to keeping these neurons in this reward circuitry functioning. However, experts have found that levels of GDNF are reduced in people with AUD during periods of alcohol abstinence, most notably in a region of the brain called the ventral tegmental area (VTA), as IFLScience notes. Therefore, the researchers decided to test whether using gene therapy to deliver more GDNF to the VTA could help reinforce this crucial dopaminergic signalling and prevent patients from suffering an alcoholic relapse. The team of scientists explained how alcohol consumption in non-addicts prompts the release of dopamine, creating a pleasurable buzz feeling, but chronic alcohol use causes the brain to adapt and stop releasing so much dopamine. “So when people are addicted to alcohol, they don’t really feel more pleasure in drinking,” Dr Kathleen Grant, a senior co-author of the study, said in a statement. “It seems that they’re drinking more because they feel a need to maintain an intoxicated state.” For their research, Dr Grant and her colleagues used eight rhesus macaque monkeys, who were exposed to increasing concentrations of alcohol over four 30-day “induction” periods. The monkeys then had free access to alcohol and water for 21 hours a day for six months, during which they developed heavy drinking behaviours. This was then followed by a 12-week abstinence phase, with the GDNF treatment performed four weeks in for half of the subjects. The gene therapy was delivered using a a viral vector containing a copy of the human GDNF gene injected directly into the primate’s VTA, according to IFLScience. And the results were truly jaw-dropping. “Drinking went down to almost zero,” Dr Grant said. “For months on end, these animals would choose to drink water and just avoid drinking alcohol altogether. They decreased their drinking to the point that it was so low we didn’t record a blood-alcohol level.” The most exciting aspect of their findings is the suggestion that gene therapy could offer a permanent solution for people with the most severe cases of AUD. This will be a welcome glimmer of hope to many, given that some 29.5 million people were diagnosed with AUD in the US alone in 2021, according to the National Institute on Alcohol Abuse and Alcoholism. Of these 29.5 million sufferers, almost a million (894,000) were aged between 12 and 17. It’ll likely be some time before we know for sure whether the gene therapy can be rolled out in humans, but it’s an important first step in tackling this devastating disorder.

Social media personality Hasbulla Magomedov has been arrested in Russia for driving offences committed after a wedding celebration. 20-year-old Hasbulla is from Russia and was arrested in his native Dagestan, a Republic of Russia, in an incident involving a group of his friends celebrating a wedding. According to reports, Hasbulla and friends blocked a main road in order to do doughnuts. Since his arrest, Hasbulla apologised for the incident on social media and confirmed it wasn’t him driving. He tweeted: “That won't happen again, people we apologise. We had to answer for it a little bit. I wasn't driving either.” Sign up to our free Indy100 weekly newsletter According to Dagestan’s Internal Affairs Ministry, the act of blocking a road to burn rubber is a common form of celebration after a wedding and added that wedding emotions got the better of those arrested. The statement read: “Unbridled wedding fun in Dagestan is known to many and far beyond the borders of the republic.” It continued: “In the absence of other ways of entertainment, such a primitive option is still extremely popular - blocking roads for other road users, burning rubber, smashing cars against each other and many other features that, in fact, have nothing to do with the celebration.” Footage of the incident was shared online and showed the social media star in a car blocking the road, while another vehicle from his party did donuts in the road in front. The statement from Dagestan’s Internal Affairs Ministry continued, explaining: “All participants of 'wedding emotions', as they themselves call it, were taken to the police, and in relation to them, employees of the State Traffic Inspectorate of the Ministry of Internal Affairs of Dagestan drew up administrative protocols for all violations.” It’s not the first time in recent months that Hasbulla’s actions have caused a stir. A few months ago the star came under fire after a clip appeared to show him abusing a cat. Have your say in our news democracy.
