Abstract

Aging is a global burden, and the increase in life span does not increase in parallel with health span. Therefore, older adults are currently living longer with chronic diseases, increased infections, and cancer. A characteristic of aging is the presence of chronic low-grade inflammation that is characterized by elevated concentrations of IL-6, TNF-α, and C-reactive protein, which has been termed inflammaging. Previous studies have demonstrated that chronic inflammation interferes with T-cell response and macrophage function and is also detrimental for vaccine responses. This raises the question of whether therapeutic strategies that reduce inflammation may be useful for improving immunity in older adults. In this review we discuss the potential causes of inflammaging, the cellular source of the inflammatory mediators, and the mechanisms by which inflammation may inhibit immunity. Finally, we describe existing interventions that target inflammation that have been used to enhance immunity during aging.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Excessive inflammation lowers vaccine efficacy and antigen-specific immunity and increases immunoregulatory mechanisms.

    “In addition, excessive inflammation has been shown to reduce vaccine efficacy (24,25), antigen-specific immunity (26) and increased immunoregulatory mechanisms to combat the increased inflammation (27).”

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.
