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.
