首个随机对照人体实验证实，“换血疗法”能够逆转衰老，3个月治疗，让人平均年轻近3岁

Core Insights - The article discusses a significant breakthrough in anti-aging research, demonstrating that Therapeutic Plasma Exchange (TPE) can effectively reverse biological age in healthy adults by an average of 2.61 years after three months of treatment [2][10]. Study Overview - The study, led by scientists from the Buck Institute for Research on Aging and Global Apheresis, involved 44 healthy volunteers aged 50 and above, assessing the safety and impact of TPE on biological age [5]. - Participants were divided into four groups with varying treatment frequencies and a placebo control group [5]. Methodology - TPE is designed to replace harmful aging-related molecules in the blood, such as inflammatory factors and senescent cell secretions [6]. - The process includes blood collection, plasma separation, plasma replacement with sterile fluids, and reinfusion of the treated blood [11]. Results - The study found that TPE is safe, with only two participants experiencing adverse events leading to treatment interruption [10]. - The most effective treatment was TPE combined with intravenous immunoglobulin (IVIG), which improved immune function and reduced chronic inflammation [10][14]. - Participants receiving TPE every two weeks showed the most significant biological age reduction, while those treated monthly also experienced benefits, albeit to a lesser extent [13]. Mechanisms of Action - TPE significantly improved age-related immune system decline and regulated immune cell composition towards a younger state [14]. - The therapy also reduced aging-promoting proteins and "rebooted" aging signal networks, affecting multiple aging-related signaling pathways [18]. Implications - This research marks a major advancement in aging studies, providing scientific evidence that biological aging can be measured, intervened, and potentially reversed [17]. - The findings suggest the potential for TPE to be used not only for disease treatment but also for health aging and preventive interventions [19]. - The study lays the groundwork for personalized anti-aging strategies based on individual biological markers [19].
