Abstract

Objective. To assess the spontaneous production of proinflammatory cytokines and immunoglobulins in rheumatoid arthritis (RA) synovitis and modulation by interleukin‐4 (IL‐4). Methods. We developed an ex vivo model of RA synovitis using pieces of RA synovium, and have studied the regulation of the production of IL‐1β, IL‐6, tumor necrosis factor α (TNFα), IgM, and IgG. Results. Spontaneous production of proinflammatory cytokines in vitro was active, with prolonged cytokine gene transcription and translation. IL‐6 was produced at higher levels than either IL‐1β or TNFα, and explants produced more IgG than IgM. In contrast, IL‐4 and interferon‐γ were undetectable. When pieces of synovium were incubated in the presence of IL‐4, reduction of spontaneous proinflammatory cytokine and Ig production was observed. Conclusion. These results extend the observations of the antiinflammatory properties of IL‐4 to an ex vivo situation, and provide the rationale for the clinical use of IL‐4 in 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.
