Immune System in Brain Tied to Alcohol Impulse

Researchers have discovered a new link between the brain’s immune system and the desire to drink alcohol.A team from the University of Adelaide has successfully turned off the impulse to drink alcohol in mice by giving them a drug that blocks a specific response from the immune system in the brain, the first to show a link between the brain’s immunity and the motivation to drink alcohol.“Alcohol is the world’s most commonly consumed drug and there is a greater need than ever to understand the biological mechanisms that drive our need to drink alcohol,” lead author Jon Jacobsen, a Ph.D. student in the University of Adelaide’s Discipline of Pharmacology, said in a statement. “Our body’s circadian rhythms affect the ‘reward’ signals we receive in the brain from drug-related behavior and the peak time for this reward typically occurs during the evening or dark phase.“We wanted to test what the role of the brain’s immune system might have on that reward and whether or not we could switch it off.”
