Swiss Study Identifies Blood Protein Differences in Centenarians

A study published by researchers from the University of Geneva and the University of Lausanne in Switzerland examined factors contributing to longevity. The research focused on blood proteins in individuals who reached 100 years of age. 03% of the population.

The team analyzed blood serum samples from centenarians, octogenarians, and adults aged 30 to 60. They measured levels of 724 proteins to identify differences in molecular aging. The findings indicate that centenarians age differently at the molecular level compared to other groups.

Centenarians showed 37 proteins with levels resembling those in younger individuals. These proteins are associated with inflammation and cardiovascular health. The proteins perform various functions in the body, including regulation of oxidative stress and tissue maintenance.

Protein Levels and Oxidative Stress Five proteins linked to oxidative stress, an imbalance between free radicals and antioxidants, were notably lower in centenarians.

Oxidative stress accelerates aging and contributes to chronic conditions such as cancer, diabetes, and Alzheimer's disease. Lower oxidative stress in centenarians results in reduced need for antioxidant proteins.
