Are zombie cells invading your brain?

Zombie cells, which are unable to die or function normally, accumulate in the brain before cognitive loss, and can be targeted to prevent diseases like Alzheimer's and Parkinson's, scientists say.

These zombie, or senescent, cells are implicated in a number of age-related diseases.

"Senescent cells are known to accumulate with advancing natural age and at sites related to diseases of ageing, including osteoarthritis; atherosclerosis; and neurodegenerative diseases, such as Alzheimer's and Parkinson's," said Darren Baker, a from Mayo Clinic in the US.


"In prior studies, we have found that elimination of senescent cells from naturally aged mice extends their healthy life span," said Baker. In the study published in the journal, the team used a model that imitates aspects of Alzheimer's disease. -- PTI
