Abstract

One explanation for the deterioration of the humoral immune response in elderly individuals is that B lymphopoiesis declines with increasing age. Recent studies report a dramatic decline in pre-B cell numbers in old mice. Surprisingly, the number of mature B cells does not decline with age. To determine if new B cells are made in aged animals despite the drop in pre-B cells, we used 5'-bromo-2-deoxyuridine labeling to determine the production rate of B cells in the bone marrow and spleen of young and old mice. Because of the great variability in the number of early B lineage cells in old mice, we acquired data on >60 young and 50 old mice throughout these experiments. The transitional and mature B cell compartments in the spleen have slower labeling kinetics in old mice as compared to young. By the end of 4 weeks of labeling, an average of only 15% of the mature B cell compartment consists of newly made cells compared to 30% in young mice. However, in contrast to an earlier report, our results indicate that there is no statistical difference in the rate of production of new immature B cells in the marrow of young and old animals. In total, our results confirm previous work showing that mature B cells in old mice have a slower turnover, but more importantly suggest that the defect in mature B cell turnover is not due to a decline in B lymphopoiesis, but rather an inability of the newly made cells to replenish the peripheral compartments.

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.
