Researchers from the Mayo Clinic have identified a new target in the battle against dementia and age-related cognitive decline – zombie cells. More formally known as senescent cells, these are cells that have stopped dividing but don’t die, and tend to accumulate with age. The new research reveals that many pathological signs of neurodegenerative disease can be eliminated by removing these cells from the brain. read more
