端粒和端粒酶是近年来老龄化文献中的热门话题,在2009年诺贝尔医学奖授予伊丽莎白·布莱克本、她的前学生卡罗尔·格雷德和杰克·绍斯塔克后,端粒和端粒酶无疑将受到更多的关注。埃佩尔和他的同事在这期BBI上发表的论文(埃佩尔等人,在出版中)代表了研究人员在这个主题上最新的优雅的行为工作,他们发表了第一篇将压力与端粒长度联系起来的论文(埃佩尔等人,2004年),这一观察结果现在已经被几个实验室证实(Damjanovic等人,2007年;帕克斯等人,2009年)。在这份报告中,他们复制了他们最初的发现,即基础端粒酶活性较低与慢性压力有关,他们还表明,急性应激源促进端粒酶活性(埃佩尔等人,在出版社)。此外,他们提供的证据表明,端粒酶活性的增加与单核细胞、淋巴细胞和特定T细胞类型的数量或百分比的变化无关,并表明应激反应的两个方面,即威胁的程度和皮质醇反应的幅度,都与端粒酶活性的较大增加有关。
Telomeres and telomerase, hot topics in the aging literature in recent years, will undoubtedly receive even more attention following the award of the 2009 Nobel Prize in Medicine “for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase” to Elizabeth Blackburn, her former student Carol Greider, and Jack Szostak. The paper by Epel and colleagues in this BBI issue (Epel et al., in press) represents the latest elegant behavioral work on this topic from the investigators who published the first paper linking stress and telomere length (Epel et al., 2004), an observation that has now been confirmed by several laboratories (Damjanovic et al., 2007; Parks et al., 2009).In this report they replicate their original finding of lower basal telomerase activity associated with chronic stress, and they also show that an acute stressor boosts telomerase reactivity (Epel et al., in press). Furthermore, they provide evidence that the increased telomerase reactivity is independent of changes in numbers or percentages of monocytes, lymphocytes, and specific T-cell types, and they show that two facets of the stress response, the degree of threat and the magnitude of the cortisol response, are both associated with larger increases in telomerase activity.
