581. 用适体标记衰老“僵尸”细胞

from 知为谁 · host 知为谁

梅奥医学中心的这项研究介绍了一种识别衰老“僵尸细胞”的新方法,该方法利用名为适体(aptamers)的微型DNA分子来精准标记这些致病细胞。衰老细胞与多种老年性疾病密切相关,但由于缺乏特异性标识,在活组织中对其进行捕捉一直是个难题。这一突破性进展最初源于两名研究生的偶然交流,随后演变为一项涉及多领域的跨实验室合作。通过从海量随机DNA序列中筛选,团队成功找到了能够与衰老细胞表面特定蛋白质结合的分子。相比传统的抗体检测,这种适体技术具有成本更低、灵活性更强的优势,有望开启抗衰老疗法与精准医疗的新篇章。该成果不仅深化了对细胞生物学的理解,也为未来在人体中监测和清除有害细胞奠定了基础。内容来源:https://www.sciencedaily.com/releases/2025/12/251213032625.htm
