- The story starts with an observation , made a few years ago , that senescent cells often produce a molecule called p16ink4a .
- 故事还得从几年前的一项实验开始讲起，他们观察到衰老的细胞通常会产生一种叫p16ink4a的分子。
- First , the researchers cleared senescent cells from the mice throughout their lives-giving the drug every 3 days beginning as soon as the animals were weaned .
- 首先，研究人员从动物断奶开始，每3天给一次药物，清除衰老细胞。
- Senescent cells make up only a small portion of cells -- some 5 % or less -- in the tissue of elderly people , but their effects can be widespread , the researchers said .
- 研究人员说，在老年人的身体组织中，衰老细胞仅占很小的比例，大约为5%或更少，但却造成了广泛的影响。
- Extensive research is still necessary to test whether the clearance of senescent cells would have the same effect in mice that age normally and whether there are different effects in different tissues , such as the brain as compared with muscle tissue , said dr. sierra of the national institute on aging .
- 美国全国老化研究所的塞拉说，还需要进行广泛研究，以测试清除衰老细胞是否会对正常老化的老鼠产生同样效果，以及在脑部等不同于肌肉组织的其它组织是否会产生不同效果。
- Another question is whether continuous clearance of senescent cells is needed to produce health benefits , or whether intermittent removal -- a spring cleaning of sorts -- is just as effective , the study 's authors said .
- 研究的作者说，还有一个问题是，是否需要持续清除衰老细胞才会产生有益于健康的效果，抑或定期清除（类似春季大扫除那种）也同样有效？
- By contrast , actually eliminating senescent cells may be a logical extension of the process of shutting them down ( they certainly cannot cause cancer if they are dead ) , and thus may not have adverse consequences .
- 相比之下，事实上消除衰老细胞可能是关闭细胞过程中的逻辑上的生命延长（这些细胞在死亡之后自然不会引发癌症），因此也就不会产生不利后果。
- Since the work relied on genetically engineered mice , it 's not directly translatable into humans , van deursen says . Researchers , however , can now screen drugs to find compounds that might activate cell death in senescent cells , he says , or that might turn the immune system against senescent cells .
- 由于这一工作依靠遗传工程小鼠，它还不能直接转化应用到人类，vandeursen说，然而，研究人员现在可以筛选相关药物，以发现可以激活衰老细胞死亡的化合物，或激活免疫系统杀死衰老细胞。
- When cells become senescent , they produce harmful compounds such as those that cause inflammation .
- 细胞衰老后会产生对人体有害的化合物，有些化合物还会引发炎症。
- Clearance of senescent cells in those mice didn 't reverse the decline that had already occurred but prevented further deterioration .
- 它们体内衰老细胞的清除并没能扭转已经发生的机能衰退，但阻止了衰老现象的进一步恶化。
- A cell that 's no longer dividing is known as senescent ; it continues to live but no longer functions as it once did .
