Abstract

In autoimmune arthritis, traditionally classified as a T helper (Th) type 1 disease, the activation of T cells results in bone destruction mediated by osteoclasts, but how T cells enhance osteoclastogenesis despite the anti-osteoclastogenic effect of interferon (IFN)-γ remains to be elucidated. Here, we examine the effect of various Th cell subsets on osteoclastogenesis and identify Th17, a specialized inflammatory subset, as an osteoclastogenic Th cell subset that links T cell activation and bone resorption. The interleukin (IL)-23–IL-17 axis, rather than the IL-12–IFN-γ axis, is critical not only for the onset phase, but also for the bone destruction phase of autoimmune arthritis. Thus, Th17 is a powerful therapeutic target for the bone destruction associated with T cell activation.

  • In rheumatoid arthritis, stimulation of bone resorption by osteoclasts is exclusively mediated by Th17 cells, which produce IL-17 to stimulate RANKL expression.

    “The authors found that, in the pathophysiology of rheumatoid arthritis, the stimulation of bone resorption by osteoclasts is exclusively mediated by Th17 cells, which produce IL-17 to stimulate RANKL expression [15,18,19].”

    From Osteoporosis: Molecular Pathology, Diagnostics, and Therapeutics (2023) · cites this paper as [19]

    The paper identifies Th17 as the exclusive osteoclastogenic subset among known CD4+ T-cell lineages (p. 2) and reports that Th17-derived IL-17 promotes osteoclastogenesis, potentially by inducing RANKL on supporting cells (p. 5). It does not say that Th17 cells exclusively mediate osteoclast-driven bone resorption in rheumatoid arthritis: the introduction (p. 2) also describes indirect effects mediated by inflammatory cytokines from synovial cells.

  • Th17 cells are an osteoclastogenic CD4+ T cell population defined by their capacity to produce IL-17.

    “Th17 cells are an osteoclastogenic population of CD4 + T cells (45,46) defined by the capacity to produce IL-17 (47).”

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.
