The protein asparagine endopeptidase (AEP) unleashes enzymes that break down brain cells’ DNA, scientists…have found…While some brain cells die directly because of lack of oxygen, others undergo programmed cell death, a normal developmental process where cells actively destroy their own DNA…At first, [scientists] thought the results of a critical experiment that led them to AEP were an aberration because the experiment was performed under overly acidic conditions.
