Healthy lifestyle may buffer against stress-related cell aging, study says
Date:7/29/2014

s the idea, at least observationally, that stressful events can accelerate immune cell aging in adults, even in the short period of one year. Exciting, though, is that these results further suggest that keeping active, and eating and sleeping well during periods of high stress are particularly important to attenuate the accelerated aging of our immune cells," said Puterman.

In recent years, shorter telomeres have become associated with a broad range of aging-related diseases, including stroke, vascular dementia, cardiovascular disease, obesity, osteoporosis diabetes, and many forms of cancer.

Research on telomeres, and the enzyme that makes them, telomerase, was pioneered by three Americans, including UCSF molecular biologist and co-author Elizabeth Blackburn, PhD. Blackburn co-discovered the telomerase enzyme in 1985. The scientists received the Nobel Prize in Physiology or Medicine in 2009 for their work.

"These new results are exciting yet observational at this point. They do provide the impetus to move forward with interventions to modify lifestyle in those experiencing a lot of stress, to test whether telomere attrition can truly be slowed," said Blackburn.
