Researchers Identify Mechanism for Clearing 'Zombie Cells' to Combat Aging and Disease
A new study led by researchers at Albert Einstein College of Medicine has identified a mechanism by which the body can clear harmful 'zombie cells,' formally known as senescent cells. These cells accumulate with age, contributing to chronic inflammation and age-related diseases. The research, published in Nature Aging, found that a decline in chaperone-mediated autophagy (CMA), a cellular recycling process, impairs both the zombie cells themselves and the immune cells responsible for their removal. By restoring CMA activity, the researchers observed a reduction in senescent-cell buildup and a decrease in the severity of lung fibrosis in mice. The study suggests that instead of solely focusing on senolytic drugs to kill these cells, restoring the body's natural clearance mechanisms through CMA activation could be a viable strategy. The team previously developed a small-molecule CMA activator, CA77.1, which showed promising results in aged mice by reducing zombie cell accumulation and signs of inflammation a...
