Abstract

Age-related decreases in immune function are thought to contribute to the reduced efficacy of vaccinations seen in elderly populations. Our previous in vitro studies demonstrated that naive CD4 T cells from aged TCR-transgenic mice proliferate less than young cells and generate poorly functioning effectors due to decreased IL-2 production. In this current study, we show that this age-related defect in CD4 T cell response also occurs in vivo and that it is correlated with reduced NF-kappa B activation. After transfer to young hosts, CD4 T cells from aged transgenic mice proliferate less and produce reduced levels of IL-2 upon immunization with Ag and alum. Introducing a combination of the inflammatory cytokines TNF-alpha, IL-1, and IL-6, or the use of an adjuvant such as CFA that induces these cytokines, markedly enhanced responses of these aged CD4 T cells, so that they proliferated and produced IL-2 similar to young cells. This enhancement is correlated with the enhanced activation of the transcription factor NF-kappa B in aged cells. We suggest that induction of inflammatory cytokines via adjuvants may enhance the efficacy of vaccinations in elderly populations.

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.
