Abstract

The past decade has seen an explosion in research focusing on innate immunity. Through a wide range of mechanisms including phagocytosis, intracellular killing and activation of proinflammatory or antiviral cytokine production, the cells of the innate immune system initiate and support adaptive immunity. The effects of aging on innate immune responses remain incompletely understood, particularly in humans. Here we review advances in the study of human immunosenescence in the diverse cells of the innate immune system, including neutrophils, monocytes, macrophages, natural killer and natural killer T (NKT) cells and dendritic cells-with a focus on consequences for the response to infection or vaccination in old age.

  • Alterations to innate immunity with ageing include impaired phagocytosis and chemotaxis of neutrophils and monocytes/macrophages, with the latter exhibiting defective antigen processing and presentation, and an inflammatory phenotype.

    “Alterations to innate immunity include impaired phagocytosis and chemotaxis of neutrophils and monocytes/macrophages, with the latter exhibiting defective antigen processing and presentation, and an inflammatory phenotype (Panda et al. 2009).”

  • Although the number of natural killer (NK) cells increases with age, cytokine production and cytotoxicity on a per cell basis decreases.

  • Ageing is associated with a lower number and altered tissue distribution of dendritic cells, which exhibit impaired antigen processing and presentation, along with decreased co-stimulatory and migratory capacity.

    “Ageing is also associated with a lower number, and altered tissue distribution of dendritic cells, which exhibit impaired antigen processing and presentation, along with decreased co-stimulatory and migratory capacity (Panda et al. 2009).”

  • Ageing results in alterations to almost all aspects of innate and adaptive immune function.

    “Ageing results in alterations to almost all aspects of innate and adaptive immune function, and these changes are typically assumed to reflect deregulation.”

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.
