Interleukin-10 (IL-10) inhibits the induction of nitric oxide synthase by interferon-γ in murine macrophages

Cunha, F.Q., Mohcada, S., Liew, F.Y.·1992·Biochemical and Biophysical Research Communications

Abstract

A murine macrophage cell line, J774, expresses high levels of the enzyme nitric oxide synthase (NOS) and produces large amounts of nitric oxide (NO) when activated with recombinant interferon (IFN)-gamma and a low concentration of LPS (10 ng/ml). Both the expression of NOS and the production of NO were inhibited by recombinant IL-10 in a dose-dependent manner. The inhibition was effective only when the cells were pretreated with IL-10; addition of IL-10 at the same time or after IFN-gamma activation was without effect. These results demonstrate that IL-10, a product of Th2 (helper T lymphocyte 2) cells, can antagonise the function of IFN-gamma, a product of Th1 cells, by modulating the mechanism of synthesis of nitric oxide in the macrophages.

Claims other papers make about this one

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

  • Macrophages exposed to IL-10 have lowered microbicidal activity and diminished capacity to respond to IFN-γ.

    “Macrophages themselves are affected by IL-10 in that exposure to this cytokine lowers their microbicidal activity and diminishes their capacity to respond to IFN-γ (63, 64).”
  • NO increases levels of anti-inflammatory cytokine IL-10 in Treg cells and some cancer cells.

    “NO also increases levels of the anti-inflammatory cytokine interleukin-10 (IL-10) in Treg cells as well as in some cancer cells [63-65].”

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.
