Abstract

T cell-dependent B-cell responses decline with age, suggesting defective CD4 T-cell function. CD4 memory T cells from individuals older than 65 y displayed increased and sustained transcription of the dual-specific phosphatase 4 (DUSP4) that shortened expression of CD40-ligand (CD40L) and inducible T-cell costimulator (ICOS) (both P < 0.001) and decreased production of IL-4, IL-17A, and IL-21 (all P < 0.001) after in vitro activation. In vivo after influenza vaccination, activated CD4 T cells from elderly individuals had increased DUSP4 transcription ( P = 0.002), which inversely correlated with the expression of CD40L ( r = 0.65, P = 0.002), ICOS ( r = 0.57, P = 0.008), and IL-4 ( r = 0.66, P = 0.001). In CD4 KO mice reconstituted with DUSP4 OT-II T cells, DUSP4 had a negative effect on the expansion of antigen-specific B cells ( P = 0.003) and the production of ova-specific antibodies ( P = 0.03) after immunization. Silencing of DUSP4 in memory CD4 T cells improved CD40L ( P < 0.001), IL-4 ( P = 0.007), and IL-21 ( P = 0.04) expression significantly more in the elderly than young adults. Consequently, the ability of CD4 memory T cells to support B-cell differentiation that was impaired in the elderly ( P = 0.004) was restored. Our data suggest that increased DUSP4 expression in activated T cells in the elderly in part accounts for defective adaptive immune responses.

  • DUSP4 induction and sustained transcription in activated CD4+ memory T cells from humans 65 and older correlates with altered cytokine production and impaired help for B cells.

    “One study reported the induction and sustained transcription of DUSP4 in activated CD4 + memory T cells from humans 65 and older, which correlated with their altered cytokine production and an impaired ability to provide help for B cells (87).”

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.
