Most people know APOE4 as the gene that raises Alzheimer's risk. Its opposite, APOE2, is linked to lower risk and longer life, and this work shows one reason why. In mice and in human stem-cell-derived cells, APOE2 kept pericytes (tiny cells that seal the blood-brain barrier) healthier, more resistant to aging, and less clogged with fat droplets. Adding APOE2 protein to APOE3 and APOE4 cells partly fixed their problems, which hints at a future drug target.
