Abstract

How environmental nutrient availability impacts T cell metabolism and function remains poorly understood. Here, we report that the presence of physiologic carbon sources (PCSs) in cell culture medium broadly impacts glucose utilization by CD8 + T cells, independent of transcriptional changes in metabolic reprogramming. The presence of PCSs reduced glucose contribution to the TCA cycle and increased effector function of CD8 + T cells, with lactate directly fueling the TCA cycle. In fact, CD8 + T cells responding to Listeria infection preferentially consumed lactate over glucose as a TCA cycle substrate in vitro , with lactate enhancing T cell bioenergetic and biosynthetic capacity. Inhibiting lactate-dependent metabolism in CD8 + T cells by silencing lactate dehydrogenase A (Ldha) impaired both T cell metabolic homeostasis and proliferative expansion in vivo . Together, our data indicate that carbon source availability shapes T cell glucose metabolism and identifies lactate as a bioenergetic and biosynthetic fuel for CD8 + effector T cells.

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

  • CD8+ T cells preferentially utilize non-glucose physiologic carbon sources as metabolic fuel.

    “Also, CD8+ T cells preferentially utilize non-glucose physiologic carbon sources as metabolic fuel, and their activation and effector function are regulated by carbon availability.9”

    From SGLT2 inhibitor promotes ketogenesis to improve MASH by suppressing CD8+ T cell activation (2024) · cites this paper as [9]

    The Discussion says that CD8+ T cells preferentially oxidize physiologic carbon sources when those sources are readily available, and the Results show that supplementation increases effector-molecule production. The Results do not establish the broader claim that carbon availability regulates activation: the measured activation/effector markers were unchanged with supplementation. (LLM, conf=0.85)

  • CD8+ T cell activation and effector function are regulated by carbon availability.

    “Also, CD8+ T cells preferentially utilize non-glucose physiologic carbon sources as metabolic fuel, and their activation and effector function are regulated by carbon availability.9”

    From SGLT2 inhibitor promotes ketogenesis to improve MASH by suppressing CD8+ T cell activation (2024) · cites this paper as [9]

    The Results section, “Physiologic carbon sources influence T cell survival and effector function” (page unavailable), reports that adding physiologic carbon sources increased CD8+ T-cell effector-molecule production. It also reports no change in the measured activation/effector markers or proliferation, so the broader claim that carbon availability regulates activation is not established, although two transcription factors changed. (LLM, conf=0.88)

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.
