Abstract

Summary: We have recently shown in non‐human primates that caloric restriction (CR) initiated during adulthood can delay T‐cell aging and preserve naïve CD8 and CD4 T cells into advanced age. An important question is whether CR can be initiated at any time in life, and whether age at the time of onset would modulate the beneficial effects of CR. In the current study, we evaluated the impact of CR started before puberty or during advanced age on T‐cell senescence and compared it to the effects of CR started in early adulthood. Our data demonstrate that the beneficial effects of adult‐onset CR on T‐cell aging were lost by both early and late CR onset. In fact, some of our results suggest that inappropriate initiation of CR may be harmful to the maintenance of T‐cell function. This suggests that there may be an optimal window during adulthood where CR can delay immune senescence and improve correlates of immunity in primates.

  • Caloric restriction slows the buildup of senescent T cells in rodents and non-human primates.

    “CR has been reported to have multiple beneficial effects on the immune system of both rodents and non-human primates that include a delay in the accumulation of senescent T cells (112) and a stimulation of thymopoiesis (113).”

  • In non-human primates, caloric restriction helps when begun in adulthood but not when begun before puberty or in old age.

    “beneficial effects were observed when it commenced in adults but were not evident when initiated in prepubertal or aged non-human primates (112).”

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.
