摘要
癌症与衰老密不可分。然而，癌症究竟是衰老过程的副产品，还是衰老细胞本身就容易发生肿瘤，这仍然是个谜。卡斯特罗、辛迪亚皮纳及其同事的一项研究证明，在自发罹患淋巴瘤的老年小鼠中，肿瘤来源于克隆扩增的老年相关 B 细胞，从而为后者提供了佐证。
Cancer and aging are inextricably linked conditions. However, whether cancer emerges as a byproduct of the aging process or whether aged cells themselves are prone to become neoplastic remains enigmatic. A study by Castro, Shindyapina and colleagues now provides support for the latter by demonstrating that in aged mice that spontaneously develop lymphomas, tumors originate from clonally expanded age-associated B cells.
