US scientists finally uncover how a rare longevity gene may protect the brain from Alzheimer's and the discovery could reshape future treatments

A rare APOE2 gene variant offers protection against brain cell aging. This gene helps brain cells repair DNA damage and resist cellular aging processes. Researchers found APOE2 neurons accumulate less DNA damage and recover faster after stress. This discovery provides new therapeutic directions for Alzheimer's disease research. Future treatments may mimic APOE2's natural protection for at-risk individuals.
