Unlike Other Cells, Brain Cells Don’t Divide Or Renew

The scientists found that PDI, on the other hand, has the power to cross into the nucleus of a cell and repair damage, which would essentially extend the life and function of these very important microscopic systems.

Brain cells are especially vulnerable. Unlike skin or blood cells, they don’t divide or renew – so any damage that builds up in them stays. And if the damage isn’t repaired, it can eventually lead to the death of these critical cells.
