Research indicates that plasma proteomics can estimate the biological age of vital organs, potentially predicting health risks. Analyzing data from 44,498 participants aged 40 to 70, the study identified aging models for 11 organs, revealing that older organs, especially the brain, correlate with increased disease risk and mortality over 17 years. The study found significant relationships between organ age gaps and various lifestyle factors, suggesting that plasma proteomics may provide noninvasive insights into organ health and longevity. Co-author Tony Wyss-Coray from Stanford highlights the brain's possible regulatory role in lifespan.
