1379-维生素C延缓灵长类骨髓衰老研究

from 聊聊Sci

这些研究资料详细介绍了灵长类动物骨髓衰老的单细胞转录组图谱,并重点探讨了维生素C对减缓衰老进程的作用。研究发现,长期补充维生素C能够显著恢复骨髓共同淋巴祖细胞的数量,并纠正由于衰老导致的骨髓细胞谱系偏向。通过对食蟹猴进行的长期实验,科学家证实维生素C能将骨髓的转录组与表观遗传年龄平均降低约4年。此外,研究揭示了颗粒蛋白前体(Progranulin)是介导维生素C发挥保护作用的关键信号分子。这些发现不仅界定了骨髓在不同解剖部位衰老的分子差异,还为干预免疫衰老提供了潜在的策略。这一成果为理解灵长类组织衰老的可逆性以及开发相关营养干预手段提供了重要依据。References:Ye Y, Zhang H, Xin Z, et al.
