Age-dependent dysregulation of innate immunity

Open access

Abstract

As we age, the innate immune system becomes dysregulated and is characterized by persistent inflammatory responses that involve multiple immune and non-immune cell types and that vary depending on the cell activation state and tissue context. This ageing-associated basal inflammation, particularly in humans, is thought to be induced by several factors, including the reactivation of latent viral infections and the release of endogenous damage-associated ligands of pattern recognition receptors (PRRs). Innate immune cell functions that are required to respond to pathogens or vaccines, such as cell migration and PRR signalling, are also impaired in aged individuals. This immune dysregulation may affect conditions associated with chronic inflammation, such as atherosclerosis and Alzheimer's disease.

  • The age-related pro-inflammatory response to immune challenge is decreased in macrophages.

    “While the age-related pro-inflammatory response to immune challenge is decreased in macrophages (91)”
  • Cellular senescence is observed in early stages of atherosclerosis, affecting different cell types in the arterial wall.

    “Cellular senescence is observed in early stages of atherosclerosis,9 affecting different cell types in the arterial wall that have distinct roles in the pathogenesis of this disease: endothelial cells (ECs),96–98 vascular smooth muscle cells (VSMCs),45,99–101 macrophages, foam cells,9,102 monocytes,103 fibroblasts,104–106 and T cells.107,108”
  • Loss-of-function of innate immune system with aging is detected in CD14+ Mono (RCC = −0.26, p = 2.68e−177).

    “Besides, the loss-function of innate immune system with aging54 is detected in CD14+ Mono (RCC = −0.26, p = 2.68e−177), which is accompanied by slight up-regulation (RCC = 0.14, p = 2.0e−47) of IFN signaling (Fig. 4g).”

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.
