Abstract

We investigated the energy‐adaptive potential of human CD4+ T cells under conditions of impaired oxidative phosphorylation (OXPHOS) and/or low glucose (inhibiting glycolysis). These cells often encounter these conditions when executing their functions in injured/inflamed tissues, even though T cells themselves require constant and adequate energy supply via ATP. We assessed two specific functions, cytokine synthesis and proliferation, and addressed whether adaptive characteristics also emerged in vivo. In glucose‐containing medium, both cytokine production and proliferation were unaffected, even under complete OXPHOS suppression. Only when glucose was also absent were these functions significantly decreased. Partial recovery of OXPHOS and induced glycolysis were crucial for the maintenance of cellular energy supply. Adaptive regulatory mechanisms are clinically relevant because hypoxia up‐regulates glycolytic genes but down‐regulates OXPHOS genes in vivo. Our data demonstrate an unexpectedly high, clinically relevant adaptive potential of human CD4+ T cells to maintain specific functions even under severely impaired bioenergetic conditions.

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

  • T cells activated at physiologic O2 tension (2-5% O2) have reduced proliferation and expansion following TCR stimulation.

    “when T cells are activated in conditions of physiologic oxygen tension (2–5 % O2, ~2–5 kPa, or ~15–38 mm Hg), there are a number of changes in T cell dynamics. First, T cells activated at physiologic O2 tension have reduced proliferation and expansion following TCR stimulation.”
  • T cells are able to preserve functionalities including cytokine production even in conditions of severe metabolite restriction including limited oxygen glucose.

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.
