Biological and social predictors of immune senescence in the aged primate

Coe, Christopher L.·2004·Mechanisms of Ageing and Development

Abstract

The transition to geriatric status occurs at around 20 years of age in monkeys after which there is typically a decline in immune responses. However, the loss in immune vigor may be quite dissociated from chronological age in some of these long-lived animals. The degree to which natural killer (NK) cell activity is sustained in aged monkeys has proven to be a valuable prognostic of ultimate health and longevity. Another useful biomarker of cellular aging in the monkey is interleukin-6 (IL-6) release. For example, when endothelial cell cultures were generated from cerebral blood vessels, those derived from aged donors produced significantly more IL-6 in response to IL-1, LPS, and hypoxia. Despite this evidence of intrinsic aging, we have found that immune responses in old animals are quite responsive to contemporaneous conditions, including changes in housing or the first onset of illness. Indeed, these changes, especially the pathological processes associated with disease, may promote many age-related immune alterations at the end of the life span.

  • Natural killer cell and lymphocyte activity, which are reported to diminish with age in monkeys and mice, were further attenuated following restraint stress in aged mice.

    “For example, natural killer cell and lymphocyte activity, which are reported to diminish with age in monkeys and mice, were further attenuated following restraint stress in aged mice (Coe, 2004;Padgett, 1998).”

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.
