Summary:
- This article provides a comprehensive overview of the APOE4 allele, the most significant genetic risk factor for late-onset Alzheimer’s disease, and its role in modulating neuroinflammation.
- It explores the mechanistic link between APOE4, the breakdown of the blood-brain barrier, and the subsequent activation of glial cells, which collectively contribute to cognitive decline.
- The text highlights the critical interplay between lipid metabolism and immune system dysregulation in the brain, offering insights into potential therapeutic targets for neurodegenerative pathology.
