Abstract

Objective: MicroRNAs (miRNA) are a new class of regulatory elements. Altered expression of miRNA has been demonstrated in the inflamed joints of patients with rheumatoid arthritis (RA). The aim of this study was to examine the role of miRNA in the pathogenesis of autoimmune arthritis, using 2 murine models. Methods: Collagen‐induced arthritis (CIA) and K/BxN serum‐transfer arthritis were induced in wild‐type (WT) and miR‐155–deficient (miR‐155 −/− ) mice. The severity of arthritis was determined clinically and histologically. Anticollagen antibodies and cytokines were measured by enzyme‐linked immunosorbent assay. The cellular composition of the draining lymph nodes after induction of CIA was measured by flow cytometry. Results: The miR‐155 −/− mice did not develop CIA. Deficiency in miR‐155 prevented the generation of pathogenic autoreactive B and T cells, since anticollagen antibodies and the expression levels of antigen‐specific T cells were strongly reduced in miR‐155 −/− mice. Moreover, Th17 polarization of miR‐155 −/− mouse T cells was impaired, as shown by a significant decrease in the levels of interleukin‐17 (IL‐17) and IL‐22. In the K/BxN serum‐transfer arthritis model, which only depends on innate effector mechanisms, miR‐155 −/− mice showed significantly reduced local bone destruction, attributed to reduced generation of osteoclasts, although the severity of joint inflammation was similar to that in WT mice. Conclusion: These results demonstrate that miR‐155 is essentially involved in the adaptive and innate immune reactions leading to autoimmune arthritis, and therefore miR‐155 might provide a novel target for the treatment of patients with RA.

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.
