Abstract

Ability to make an optimal immune response to vaccines and infectious agents declines with age in humans and animal models. Recent advances have shown intrinsic B cell defects in aged mice and humans, including decreases in Ig class switch recombination (CSR), activation-induced cytidine deaminase (AID), and E47 transcription factor. Effects on somatic hypermutation (SHM) have been varied depending on the system studied. Increase of AID in mice has shown improved CSR but not SHM. The reported microarray analysis of human B cell subsets may now be used to delineate B cell defects with aging and all the advances presented should lead to selecting agents for improved immune response in the elderly.

  • Some age-related B cell deficiencies may occur secondary to T cell deficiencies.

    “In view of the critical role played by CD4 + T cells in orchestrating the immune response, some of the age-related deficiencies observed in B cells (51,53,54), which include a reduction in the number of plasmablasts that develop in response to influenza vaccination (55) and the production of poor-quality antibodies to carbohydrate antigens (56)(57)(58), may occur secondary to T cell deficiencies.”

  • B cell number in mice is unchanged by aging, but in human peripheral blood the absolute number is reduced.

    “B cell number in mice is unchanged by aging, but in human peripheral blood their absolute number is reduced (51).”

  • The decline in human B cell number is likely due to fewer IgM+ memory and switched memory B cells, because total naive B cells remain unchanged by aging.

    “This decline is likely due to decreased numbers of IgM + memory and switched memory B cells, because the total number of naive B cells remains unchanged by aging (51,52).”

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.
