“换血疗法”，真能够逆转衰老？

Core Insights - The study conducted by Buck Institute for Research on Aging demonstrates that Therapeutic Plasma Exchange (TPE) can significantly reverse biological age in healthy adults, with an average reduction of 2.61 years after three months of treatment [1][13][21] Group 1: Study Overview - The research titled "Multi-Omics Analysis Reveals Biomarkers That Contribute to Biological Age Rejuvenation in Response to Single-Blinded Randomized Placebo-Controlled Therapeutic Plasma Exchange" was published in Aging Cell [2] - The clinical trial involved 44 healthy volunteers aged 50 and above, assessing the safety and impact of TPE on biological age [4] - Participants were divided into four groups with varying treatment frequencies and a placebo group [4] Group 2: Treatment Methodology - TPE is designed to replace harmful aging-related molecules in the blood, such as inflammatory factors and senescent cell secretions [5][6] - The procedure involves blood collection, plasma separation, plasma exchange, and reinfusion of new blood free from harmful substances [5][6] Group 3: Study Results - The study found that TPE is safe, with only 2 out of 44 participants experiencing adverse events leading to treatment interruption [10] - TPE significantly improved biological age markers, with 15 epigenetic clocks showing rejuvenation effects compared to the placebo group [11] - The most effective treatment was TPE combined with intravenous immunoglobulin (IVIG), which reversed age-related immune decline [12][16] Group 4: Implications and Future Directions - The research indicates that TPE can potentially be used for health aging and preventive interventions, highlighting its significance beyond disease treatment [22] - The findings pave the way for developing more convenient and effective anti-aging therapies, such as targeted drugs and new plasma purification technologies [21][22] - The study emphasizes the potential for personalized anti-aging plans based on individual biomarker profiles [22]
