Stress Exacerbates Age-Related Decrements in the Immune Response to an Experimental Influenza Viral Infection

Abstract

To test the hypothesis that stress exacerbates immune decrements associated with aging, the impact of restraint stress on immunosenescence was assessed using an experimental model of influenza A/Puerto Rico/8/34 viral infection. Beginning one day prior to infection, male C57BL/6 mice, 3 and 22 months of age, were subjected nightly to 12 hours of restraint stress. In both age groups, restraint induced a comparable increase in serum corticosterone levels. However, in contrast to the 3-month-old controls, serum corticosterone levels in 22-month-old mice returned to baseline slower after removal of the stressor. The characteristic influenza-driven increase in cellularity of the lung and draining lymph node was decreased by age and further suppressed by stress. Natural killer cell activity and virus-specific T helper cell function were also blunted by age and almost completely abrogated by stress. Furthermore, due to the weak immune response to viral infection, aged animals subjected to stress had a lower survival rate than age-matched controls.

  • 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.
