Abstract

Recent advances allow aging-associated changes in B-cell function to be approached at a mechanistic level. Reduced expression of genes crucial to lineage commitment and differentiation yield diminished B-cell production. Moreover, intrinsic differences in the repertoire generated by B-cell precursors in aged individuals, coupled with falling B-cell generation rates and life-long homeostatic competition, result in narrowed clonotypic diversity. Similarly, reductions in gene products crucial for immunoglobulin class switch recombination and somatic hypermutation impact the efficacy of humoral immune responses. Together, these findings set the stage for integrated analyses of how age-related changes at the molecular, cellular and population levels interact to yield the overall aging phenotype.

  • During ageing, remodelling of peripheral B cell subsets occurs with a decline in B cell production in the bone marrow and expansion of atypical B cell subsets such as ABCs and DN B cells.

    “During ageing, a remodelling of peripheral B cell subsets occurs with a decline in B cell production in the bone marrow and the expansion of atypical B cell subsets, such as age-associated B cells (ABCs) and double-negative (DN) B cells.”

    From Is there a role for B cells in Alzheimer's disease? (2026) · cites this paper as [65]

    The sections “B-cell production wanes with age” and “Homeostatic relationships shift with age” report reduced bone-marrow B-cell output and age-related changes in mature B-cell subsets. They discuss B1 and marginal-zone B cells, but do not identify an expansion of age-associated B cells (ABCs) or double-negative (DN) B cells. Page numbers are unavailable in our copy.

  • Advancing age is accompanied by profound qualitative changes in the peripheral B cell repertoire with reduced clonotypic diversity and a shift towards autoreactive specificities.

    “Advancing age is accompanied by profound qualitative changes in the peripheral B cell repertoire with reduced clonotypic diversity and a shift towards autoreactive specificities [65 -68].”

    From Is there a role for B cells in Alzheimer's disease? (2026) · cites this paper as [65]

    The “BCR diversity truncates with age” section reports a significant loss of peripheral-blood B-cell diversity in some older subjects, not all older people. “Homeostatic relationships shift with age” says autoreactive cells might enter the primary repertoire and notes age-associated autoreactive antibodies in mouse strains, but it does not establish a general shift of the peripheral B-cell repertoire toward autoreactive specificities.

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.
