Abstract

Summary: A number of immunological functions are dependent on circadian rhythms and regular sleep. This has impact on the type and magnitude of immune responses following antigenic challenge, for example in vaccination. Little is known about the underlying mechanisms. One possibility may be the circadian and sleep-dependent modulation of CD4+CD25- T cell responses by CD4+CD25+ natural regulatory T cells (nTreg). In a variety of studies, nTreg have been shown to regulate T cell responses negatively. Thus, we investigated the influence of sleep and circadian rhythm on the number and function of nTreg as well as on the function of CD4+CD25- T cells. Seven healthy young men were examined under defined conditions on two occasions, i.e. during sleep and sleep deprivation. Venous blood was drawn periodically; numbers of nTreg, suppressive activity of nTreg, interleukin-2 production and proliferation of CD4+CD25- T cells were explored in vitro. nTreg counts revealed a significant circadian rhythm with highest levels during the night (mean 95 nTreg/µl) and lowest levels during the day (mean 55 nTreg/µl). During normal sleep, the suppressive activity of nTreg was highest at 02.00 h and somewhat lower at 15.00 h. Surprisingly, almost no suppressive activity was present at 07.00 h. Deprivation of sleep abrogated this rhythm. CD4+CD25– T cell proliferation was dampened significantly by sleep deprivation. This is the first study in human cells to show that nTreg number and function follow a rhythm across the 24-h period. Furthermore, sleep deprivation severely disturbs the functional rhythm of nTreg and CD4+CD25– T cells.

  • Several reports indicated an enhancing influence of sleep on T-cell production of IL-2 which acts to further promote T-cell growth, proliferation, and differentiation, although other studies failed to reveal such effects when examining IL-2 production in specific T-cell subpopulations.

    “Furthermore, several reports indicated an enhancing influence of sleep on T-cell production of IL-2 which acts to further promote T-cell growth, proliferation, and differentiation (120, 595), although other studies failed to reveal such effects when examining IL-2 production in specific T-cell subpopulations (109,308).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
