Scientists Restore Key Alzheimer’s Pathway

Dementia Declining Brain Cognition
Scientists discovered that elevated oxysterol traps ABCA1 in lysosomes, disrupting cholesterol metabolism and increasing Alzheimer’s risk. Lowering oxysterol restored ABCA1 function and reduced inflammation, suggesting a new treatment approach.

Researchers combined animal models, human brain tissue, and molecular analysis to uncover a connection between Alzheimer’s disease, cell function issues, and cholesterol in the brain.

A research team from the Keck School of Medicine at USC has identified the mechanisms of a cellular pathway that drives inflammation and aging, particularly in individuals with the APOE4 genetic risk for Alzheimer’s disease. Their study also reveals a method for restoring cells to a healthy state, offering a potential new avenue for treatment. This discovery, the result of a…
