Scientists found the hidden switch fueling alzheimer’s brain inflammation
Researchers at Scripps Research have identified a protein modification called S-nitrosylation that causes the STING protein to trigger chronic brain inflammation in Alzheimer's patients. Blocking this chemical switch in experimental models successfully reduced inflammation and protected brain cell connections.
Why it matters
This discovery identifies a specific molecular target that could lead to new, more effective therapeutic treatments for Alzheimer's disease.
The brain has its own built in immune defenses that help detect threats and protect nerve cells. But growing evidence suggests that in Alzheimer's disease, these immune cells become stuck in a state of chronic activation. Instead of helping, they trigger ongoing inflammation that can damage the connections between brain cells.
