Alcohol Doesn't Just Affect Neurons - It Triggers Immune Cells to Destroy The Brain's Structural Matrix, Mouse Study Shows
Yahoo • • health
Key Points:
- New research published in Immunity reveals that alcohol affects not only neurons but also microglia, immune cells in the brain, causing them to dismantle the extracellular matrix that supports brain cells.
- In mouse models simulating binge drinking, alcohol triggered microglia to change shape, reduce their surveillance activity, and break down the extracellular matrix, leading to synaptic loss and neuronal dysfunction.
- Disabling the MyD88 protein in microglia reduced alcohol-induced brain damage and sedation in genetically engineered mice, highlighting MyD88 as a potential therapeutic target.
- Analysis of human brain tissue from individuals with alcohol use disorder showed similar extracellular matrix disruption, suggesting that microglial-driven brain damage occurs in humans as well.
- Researchers aim to explore treatments targeting microglia or protecting the extracellular matrix to prevent brain damage from alcohol and possibly other neurological diseases.
