Cancer May Offer Protection Against Alzheimer's Disease, New Study Suggests

A new scientific study suggests that cancer may offer protection against Alzheimer's disease. Researchers have discovered that cystatin C, a protein produced by cancer cells, has the ability to break down the amyloid plaques that characterize Alzheimer's disease. In experiments with mice, the protein penetrated the brain and activated immune cells, leading to the breakdown of the plaques. If these findings are confirmed in humans, they could pave the way for new treatments for Alzheimer's disease. The study was published in the journal Nature.
