Scientists Identify Potential Driver of Chronic Brain Inflammation, Offering New Insights Into Alzheimer’s Disease
—————————————-
Researchers have identified a biological mechanism that may contribute to chronic brain inflammation in people with Alzheimer’s disease, a discovery that could help guide the development of more effective therapies.

According to a report published by Scripps Research and covered by ScienceDaily, scientists found that a protein called STING (Stimulator of Interferon Genes) can become persistently activated in the brains of Alzheimer’s patients due to chemical changes associated with the disease. This sustained activation appears to keep immune cells in a heightened inflammatory state.

The research suggests that ongoing STING activation may drive prolonged inflammation in the brain, which in turn damages neural connections and contributes to the progression of Alzheimer’s pathology.

The findings provide new understanding of how immune signaling pathways may exacerbate neurodegeneration and point to potential targets for future therapeutic intervention aimed at reducing harmful inflammation in Alzheimer’s disease.
