Abstract

Dendritic cells (DCs) are key regulators of innate and acquired immunity. The maturation of DCs is directed by signal transduction events downstream of toll-like receptors (TLRs) and other pattern recognition receptors. Here, we demonstrate that, in mouse DCs, TLR agonists stimulate a profound metabolic transition to aerobic glycolysis, similar to the Warburg metabolism displayed by cancer cells. This metabolic switch depends on the phosphatidyl inositol 3′-kinase/Akt pathway, is antagonized by the adenosine monophosphate (AMP)–activated protein kinase (AMPK), and is required for DC maturation. The metabolic switch induced by DC activation is antagonized by the antiinflammatory cytokine interleukin-10. Our data pinpoint TLR-mediated metabolic conversion as essential for DC maturation and function and reveal it as a potential target for intervention in the control of excessive inflammation and inappropriately regulated immune responses.

  • The increased degradation of key enzymes SUCLA2, ALDH2, and ACO2 is consistent with a reported shift in LPS-stimulated DCs from oxidative phosphorylation and oxygen consumption to glycolysis, glucose consumption, and lactate production.

    “The increased degradation of key enzymes, such as SUCLA2, ALDH2 and ACO2, is consistent with a reported shift in LPS-stimulated DCs from oxidative phosphorylation and oxygen consumption to glycolysis, glucose consumption and lactate production (39–42).”
  • TCR/CD28 stimulation of T cells, surface immunoglobulin stimulation on B cells, and TLR stimulation of macrophages and DCs all promote changes in aerobic glycolysis characteristic of the Warburg effect.

    “TCR/CD28 stimulation of T cells (6), the stimulation of surface immunoglobulin on B cells (41), and TLR stimulation of macrophages and dendritic cells (DCs) (42, 43) all promote changes in aerobic glycolysis characteristic of the Warburg effect.”
  • The increase in IL-10 production may be explained by increased flux of pyruvate into the TCA cycle, because M2 macrophage activity may require mitochondrial oxidative metabolism.

    “This could explain the increase in IL-10 production, which in the case of M2 macrophage activity may require mitochondrial oxidative metabolism (Krawczyk et al., 2010).”

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.
