Abstract

Osteoclast progenitors differentiate into mature osteoclasts in the presence of receptor activator of NF-kappaB (RANK) ligand on stromal or osteoblastic cells and monocyte macrophage colony-stimulating factor (M-CSF). The soluble RANK ligand induces the same differentiation in vitro without stromal cells. Tumor necrosis factor-alpha (TNF-alpha), a potent cytokine involved in the regulation of osteoclast activity, promotes bone resorption via a primary effect on osteoblasts; however, it remains unclear whether TNF-alpha can also directly induce the differentiation of osteoclast progenitors into mature osteoclasts. This study revealed that TNF-alpha directly induced the formation of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cells (MNCs), which produced resorption pits on bone in vitro in the presence of M-CSF. The bone resorption activity of TNF-alpha-induced MNCs was lower than that of soluble RANK ligand-induced MNCs; however, interleukin-1beta stimulated this activity of TNF-alpha-induced MNCs without an increase in the number of MNCs. In this case, interleukin-1beta did not induce TRAP-positive MNC formation. The osteoclast progenitors expressed TNF receptors, p55 and p75; and the induction of TRAP-positive MNCs by TNF-alpha was inhibited completely by an anti-p55 antibody and partially by an anti-p75 antibody. Our findings presented here are the first to indicate that TNF-alpha is a crucial differentiation factor for osteoclasts. Our results sugges…

  • TNF-α induces osteoclastogenesis in RANKL- and M-CSF-positive hematopoietic cell precursors, with effects mediated by TNF-α receptors type 1 and type 2, the former being most effective in inducing differentiation of TRAP-positive multinucleated cells.

    “TNF-α induces osteoclastogenesis in RANKL- and M-CSF-positive hematopoietic cell precursors [29,30], where its effects are mediated by TNF-α receptors type 1 (p55r) and type 2 (p75r), the former being the most effective in inducing the differentiation of TRAP-positive multinucleated cells [31].”

  • IL-1β enhances the ability of TNF-α to upregulate bone resorption by TRAP-positive multinucleated cells.

    “Azuma and associates found that IL-1β enhanced the ability of TNF-α to upregulate bone resorption by TRAP-positive multinucleated cells [31].”

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.
