1027-人类衰老多维评估框架与多模态时钟研究

from 聊聊Sci

本研究介绍了一项名为“耄耋计划”的大规模科研成果,旨在通过建立多维衰老时钟系统来精准评估人类的生物学年龄。研究人员通过收集两千余名中国志愿者的临床、生理及多组学数据,构建了包含核心功能时钟、多模态时钟及器官特定时钟在内的综合评估框架。该研究揭示了衰老在不同组织间的异步性特征,并证实了生物标志物与衰老轨迹在多中心样本中具有高度的一致性。通过对血浆蛋白质谱的深度解析,科学家们发现凝血因子的积聚不仅是衰老的关键信号,更是驱动血管与全身衰老的核心机制。这一系统性框架不仅为量化人体衰老提供了科学标准,也为开发针对性的抗衰老干预策略奠定了重要基础。References:Li J, Jiang B, Zhang W, et al.
