De ce doi oameni de aceeași vârstă îmbătrânesc diferit? Descoperirea care ar putea schimba prevenirea bolilor • Newsweek România

Research indicates that differences in immune system aging may explain why individuals of the same age experience varying health outcomes. Scientists have identified specific immune cell types linked to chronic disease risk and mortality. A favorable ratio of cells producing granzyme K is associated with healthier aging, while a predominance of granzyme B-producing cells correlates with higher health risks. This discovery could lead to a blood test that predicts health issues years before symptoms appear. The study analyzed blood samples from over 2,600 adults and suggests that immune profile changes can indicate future health risks, although further validation is needed before clinical application.
