APOE2 Lets Neurons Fight DNA Damage, Slowing Brain Aging
TL;DR Summary
Buck Institute researchers show that APOE2 helps neurons repair DNA and resist aging by reducing DNA damage and cellular senescence; studies in human iPSC-derived neurons and aged mice reveal APOE2–driven DNA repair activation and better nuclear integrity, offering a potential mechanism for APOE2's lower Alzheimer’s risk and longer lifespan and suggesting therapies that boost DNA repair for APOE4 carriers.
