Abstract

We have established by differential display polymerase chain reaction of mRNA that interleukin (IL)-18 is expressed by osteoblastic stromal cells. The stromal cell populations used for comparison differed in their ability to promote osteoclast-like multinucleated cell (OCL) formation. mRNA for IL-18 was found to be expressed in greater abundance in lines that were unable to support OCL formation than in supportive cells. Recombinant IL-18 was found to inhibit OCL formation in cocultures of osteoblasts and hemopoietic cells of spleen or bone marrow origin. IL-18 inhibited OCL formation in the presence of osteoclastogenic agents including 1α,25-dihydroxyvitamin D3, prostaglandin E2, parathyroid hormone, IL-1, and IL-11. The inhibitory effect of IL-18 was limited to the early phase of the cocultures, which coincides with proliferation of hemopoietic precursors. IL-18 has been reported to induce interferon-γ (IFN-γ) and granulocyte/macrophage colony-stimulating factor (GM–CSF) production in T cells, and both agents also inhibit OCL formation in vitro. Neutralizing antibodies to GM–CSF were able to rescue IL-18 inhibition of OCL formation, whereas neutralizing antibodies to IFN-γ did not. In cocultures with osteoblasts and spleen cells from IFN-γ receptor type II–deficient mice, IL-18 was found to inhibit OCL formation, indicating that IL-18 acted independently of IFN-γ production: IFN-γ had no effect in these cocultures. Additionally, in cocultures in which spleen cells were derived from receptor-deficient mice and osteoblasts were from wild-type mice and vice versa, we identified that the target cells for IFN-γ inhibition of OCL formation were the hemopoietic cells. The work provides evidence that IL-18 is expressed by osteoblasts and inhibits OCL formation via GM–CSF production and not via IFN-γ production.

  • IL-18 inhibits osteoclastogenesis by downregulating osteoblast production of M-CSF.

    “Using co-cultures of osteoblasts and hematopoietic cells, Udagawa and associates found that IL-18 inhibited osteoclastogenesis by downregulating osteoblast production of M-CSF [48].”

    From Osteoclasts and Microgravity (2020) · cites this paper as [48]

    The Results section, “IL-18 Inhibits OCL Formation Via GM–CSF” (page unavailable), attributes the inhibition to increased production of GM–CSF. It does not identify downregulation of osteoblast M-CSF production as the mechanism; M-CSF and GM–CSF are different factors. (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.
