Cure One, Cure Many Award recipient Dr. Caghan Kizil has been featured in a news article about a new study of the APOE gene. It found that the APOE2 variant helps repair DNA, thereby protecting the brain from Alzheimer’s disease and the effects of aging. https://buff.ly/r958Rcj

APOE2 carriers’ brain cells repair DNA twice as fast as others—fewer breaks, more repair proteins, less aging debris. Their neurons literally stay younger longer. https://s.fitbodyscience.com/Ypc3DT

The breakdown

A rare gene variant might be the brain’s secret weapon against aging and Alzheimer’s.

Other research found that people with the APOE2 variant have brain cells that are better at fixing DNA damage, and those cells also show fewer signs of aging compared to those with other versions of the gene. This suggests APOE2 might help shield the brain from some of the damage linked to Alzheimer’s, though it’s not a guaranteed shield. The study didn’t test whether this directly prevents dementia in people, just that the cellular machinery works better. It’s a promising clue, not a cure.

Bottom line

So while having this gene variant doesn’t mean you’re immune, it might give your brain a little extra repair power as you age.
