Age-related changes in natural killer cell repertoires: impact on NK cell function and immune surveillance

Abstract

A key feature of human natural killer (NK) cells, which enables efficient recognition of infected and malignant target cells, is the expression of HLA class I-specific receptors of the KIR and NKG2 gene families. Cell-to-cell variability in receptor expression leads to the formation of complex NK cell repertoires. As outlined here, NK cells go through major changes from newborns to adults characterized by downregulation of the inhibitory NKG2A receptor and concomitant upregulation of KIR family members. This process is completed in young adults, and in the majority of individuals, KIR/NKG2A repertoires remain remarkably stable until old age. Nonetheless, age-related factors have the potential to majorly influence the complexity of NK cell repertoires: Firstly infection with HCMV is associated with major clonal expansions of terminally differentiated NKG2C- and KIR-expressing NK cells in certain individuals. Secondly, ineffective hematopoiesis can lead to immature and less diversified NK cell repertoires as observed in myelodysplastic syndrome (MDS), a malignant disease of the elderly. Thus, whereas in the majority of elderly the NK cell compartment appears to be highly stable in terms of function and phenotype, in a minority of subjects a breakdown of NK cell repertoire diversity is observed that might influence immune surveillance and healthy aging.

  • Many immune cell subsets become hyporesponsive to acute challenges with age.

  • In immunosenescence, activating receptor expression of NK cell markers NKP30, NKP46, etc., is reduced, while inhibitory receptor expression of KIR, NKG2C, etc., is increased.

    “It should be noted that, in the process of immunosenescence, the activating receptor expression of natural killer (NK) cell markers NKP30, NKP46, etc., is reduced, while the inhibitory receptor expression of KIR, NKG2C, etc., is increased [45, 46].”

  • Two subpopulations of NK cells, immature CD14+CD56dim and mature CD14+CD56bright, are associated with aging and remodeling of mature NK cell subsets, and reduced expression of activated receptors may promote the escape of NK cells in the elderly.

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.
