Abstract

Innate immune cells, including macrophages, have recently been identified as target cells for thyroid hormone. We hypothesized that optimal intracellular concentrations of the active thyroid hormone triiodothyronine (T3) are essential for proinflammatory macrophage function. T3 is generated intracellularly by type 2 deiodinase (D2) and acts via the nuclear thyroid hormone receptor (TR). In zebrafish embryos, D2 knockdown increased mortality during pneumococcal meningitis. Primary murine D2 knockout macrophages exhibited impaired phagocytosis and partially reduced cytokine response to stimulation with bacterial endotoxin. These effects are presumably due to reduced intracellular T3 availability. Knockdown of the main TR in macrophages, TRα, impaired polarization into proinflammatory macrophages and amplified polarization into immunomodulatory macrophages. Intracellular T3 availability and action appear to play a crucial role in macrophage function. Our data suggest that low intracellular T3 action has an anti-inflammatory effect, possibly due to an effect on macrophage polarization mediated via the TRα. This study provides important insights into the link between the endocrine and innate immune system.

  • DIO2 knockdown impairs macrophage phagocytosis while blunting the cytokine response upon stimulation with bacterial endotoxin.

    “In addition, DIO2 knockdown impairs macrophage phagocytosis while blunting the cytokine response upon stimulation with bacterial endotoxin [36, 37].”

    From An update on non-thyroidal illness syndrome (2021) · cites this paper as [37]

    The section on D2KO macrophages reports impaired phagocytosis and reduced GM-CSF transcription after LPS stimulation. But these experiments used D2 knockout cells rather than DIO2 knockdown, and the other measured cytokine responses were unchanged. The Discussion says the findings accord with earlier knockdown data, but this paper does not establish a generally blunted cytokine response from knockdown. (LLM, conf=0.88)

  • DIO2 knockdown increases mortality in zebrafish embryos during pneumococcal meningitis, which can be restored by T3 administration during infection.

    “Finally, DIO2 knockdown increases mortality in zebrafish embryos during pneumococcal meningitis, which can be restored by T3 administration during infection [37].”

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.
