In the hours after death, some cells in the human brain not only remain active, they grow in size.
According to researchers, obese mice have increased levels of senescent cells in their brains, and these cells contribute to anxiety. Using senolytics to clear the cells helps to reduce anxiety related behaviors.
Researchers report senescent, or Zombie, cells accumulate in certain neurons prior to cognitive loss. By preventing accumulation of these cells, researchers were able to diminish apoptosis, memory loss and tau aggregation.
