Abstract

The regulation of macrophage orientation pathological conditions is important but still incompletely understood. Here, we show that IL-10 and Rag1 double knockout mice spontaneously develop colitis with dominant M1 macrophage phenotype, suggesting that IL-10 regulates macrophage orientation in inflammation. We demonstrate that IL-10 stimulation induced miR-146b expression, and that the expression of miR-146b was impaired in IL-10 deficient macrophages. Our data show that miR-146b targets IRF5, resulting in the regulation of macrophage activation. Furthermore, miR-146b deficient mice developed intestinal inflammation with enhanced M1 macrophage polarization. Finally, miR-146b mimic treatment significantly suppresses M1 macrophage activation and ameliorates colitis development in vivo. Collectively, the results suggest that IL-10 dependent miR-146b plays an important role in the modulation of M1 macrophage orientation.

  • In a mouse model, knock-out of miR-146a led to colitis, which could be ameliorated upon administration of miR-146a mimic.

    “In a mouse model, knock-out of miR-146a led to colitis, which could be ameliorated upon administration of miR-146a mimic [151].”

    From MicroRNAs as Regulators of Phagocytosis (2022) · cites this paper as [151]

    The Results sections on miR-146b deficiency and mimic treatment report intestinal inflammation in miR-146b-knockout mice, but test the miR-146b mimic for colitis in IL-10-knockout mice. The paper identifies miR-146b, not miR-146a, throughout these findings; it does not report treating miR-146a-knockout mice with a miR-146a mimic. Page numbers were not available in our copy. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • miR-146b takes part in M2 polarization, is upregulated upon IL-10 stimulation, and targets interferon regulatory factor 5 (IRF5).

    “The authors confirmed that miR-146b takes part in M2 polarization and it is upregulated upon IL-10 stimulation, and targets interferon regulatory factor 5 (IRF5).”

    From MicroRNAs as Regulators of Phagocytosis (2022) · cites this paper as [151]

    The Results section, “miR-146b Induced by IL-10 Suppresses M1 Macrophage Polarization” (page unavailable), and the Discussion support IL-10-dependent miR-146b expression and its targeting of IRF5. They describe suppression of M1 polarization, not a demonstrated role in M2 polarization. (LLM, conf=0.90)

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.
