Abstract

Summary: In this study we analysed the effects of age on T and B lymphocytes in human lymph nodes by comparing lymphocyte subsets in paraffin sections from lymph node tissue taken from healthy young and elderly people. We demonstrate that the relative number of CD8+ T cells decreases with age but that the relative number of CD4+ T cells does not. There is also a very pronounced age‐dependent loss of CD45RA+ naïve T cells. The number and size of follicles and the relative number of CD20+ B cells are similar in young and elderly donors. For polymerase chain reaction analysis of the T‐cell receptor (TCR) repertoire the TCR‐γ gene rearrangements were used as a marker of clonality. This is a reliable tool to detect not only clonal TCR‐γδ populations but also TCR‐αβ populations. Young donors with clonal T‐cell expansions in their lymph node tissue do, however, have a higher number of CD20+ B cells, a higher relative size of germinal centres compared to the follicle mantles and a higher number of immunoglobulin M‐expressing cells than young donors without evidence of clonal T‐cell expansions. Corresponding changes are not observed in elderly donors with clonal T‐cell expansions in their lymph node tissue. In summary our findings demonstrate characteristic effects of aging on human lymph node tissue, the most striking feature being the depletion of naïve T cells and the apparent dysregulation of T‐cell/B‐cell interactions in old age.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ageing changes can include fewer naive B and T cells.

    “These changes can include an involuted thymus235, fewer naive B and T cells236, diminished T cell receptor diversity237, higher susceptibility to T cell apoptosis238 and reduced expression of crucial receptors such as CD28 on cytotoxic CD8+ T cells239.”

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.
