Abstract

NK cells are key players in the fight against persistent viruses. Human cytomegalovirus (HCMV) infection is associated with the presence of a population of CD16+ CD56 dim NKG2C+ NK cells in both acutely and latently infected individuals. Here, we studied the nature of these terminally differentiated NK cells in different human populations infected with HCMV: healthy donors stratified by age, thymectomized individuals, pregnant women suffering from primary CMV infection, and lung transplant patients. Both CD16+ CD56 dim NK‐ and CD8 T‐cell phenotypes as well as functional capacities were determined and stratified according to age and/or CMV event. Similarly to T‐cell responsiveness, we observe an accumulation over time of NKG2C+ NK cells, which preferentially expressed CD57. This accumulation is particularly prominent in elderly and amplified further by CMV infection. Latent HCMV infection (without replication) is sufficient for NKG2C+ CD57+ NK cells to persist in healthy individuals but is not necessarily required in old age. Collectively, the present work supports the emerging concept that CMV shapes both innate and adaptive immunity in humans.

  • A decrease in NKG2A expression occurs from young to elderly adults.

    “A decrease in NKG2A expression occurs from young to elderly adults [104, 105].”
  • Unusual clonal expansion of NKG2C+CD57+ NK cells has been found in elderly CMV-seronegative donors, indicating that parameters related to aging other than CMV could influence the peripheral repertoire.

    “this unusual clonal expansion of NKG2C+CD57+ NK cells has been found in elderly CMV-seronegative donors, indicating that parameters related to aging other than CMV could influence the peripheral repertoire [105].”
  • CMV infection could be a parameter associated with expansion of long-lived memory-like NK cells characterized by CD94/NKG2C and CD57 expression.

    “Recent evidence has demonstrated that CMV infection could be a parameter associated with this expansion of long-lived ‘memory-like’ NK cells, which are characterized by the expression of CD94/NKG2C and CD57 [105, 109].”

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.
