SloveniaA new study has shown that alcohol consumption triggers changes in the brain that affect not just nerve cells but also the brain's resistance to damage. Scientists discovered an unexpected role of microglia, immune cells that typically protect the central nervous system from injury. Alcohol affects brain function shortly after consumption, with microglia beginning to break down the extracellular matrix, a network that supports brain cells and maintains connections between neurons. In experiments on mice, researchers observed these changes within an hour of alcohol exposure, noting that repeated exposure led to more pronounced effects. The breakdown of this supportive structure could impair neural connections, reducing their efficiency. The findings were published in the scientific journal *Immunity* and involved analyzing brain tissue from six deceased individuals with alcohol-related disorders. While the results suggest similar processes might occur in human brains, further research is needed due to limitations in extrapolating mouse studies to humans.
