Abstract

Cytomegalovirus (CMV)-seropositivity has been shown to have a negative effect on influenza vaccine-specific antibody responses. In this paper, we confirm and extend these results showing for the first time, a negative association between CMV-seropositivity and B cell predictive biomarkers of optimal vaccine responses. These biomarkers are switched memory B cells and AID in CpG-stimulated B cell cultures measured before vaccination which positively correlate with the serum response to the influenza vaccine. We also found that CMV-seropositivity is associated with increased levels of B cell-intrinsic inflammation and these both correlate with lower B cell function. Finally, CMV-seropositivity is associated with decreased percentages of individuals responding to the vaccine in both young and elderly individuals.

  • These intrinsic B-cell defects include decreases in expression and function of the transcription factor E47.

    “and include decreases in expression and function of the key transcription factor E47 (see below), along with a reduction in activation-induced cytidine deaminase (AID), the enzyme of class switch recombination and somatic hypermutation.”

  • Age-related intrinsic B-cell defects responsible for sub-optimal antibody responses in elderly to infections and vaccines have been identified.

  • Immune changes associated with HCMV may have significant impact during co-infection and vaccination, as well as on general and immunological fitness.

    “Immune changes associated with HCMV may have significant impact during co-infection and vaccination, as well as on general and immunological fitness.”
  • The correlation between HCMV positivity and impaired responses is controversial because this relationship is observed in some but not all studies.

    “However, the correlation between HCMV positivity and impaired responses is controversial because this relationship is observed in some but not all studies (54–56).”

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.
