Abstract

Objective: To study the contribution of interferon‐α (IFNα) and IFNγ to the IFN gene expression signature that has been observed in microarray screens of peripheral blood mononuclear cells (PBMCs) from patients with systemic lupus erythematosus (SLE). Methods: Quantitative real‐time polymerase chain reaction analysis of healthy control PBMCs was used to determine the relative induction of a panel of IFN‐inducible genes (IFIGs) by IFNα and IFNγ. PBMCs from 77 SLE patients were compared with those from 22 disease controls and 28 healthy donors for expression of IFIGs. Results: Expression of IFNα‐inducible genes was significantly higher in SLE PBMCs than in those from disease controls or healthy donors. The level of expression of all IFIGs in PBMCs from SLE patients with IFNα pathway activation correlated highly with the inherent responsiveness of those genes to IFNα, suggesting coordinate activation of that cytokine pathway. Expression of genes preferentially induced by IFNγ was not significantly increased in SLE PBMCs compared with control PBMCs. IFNα‐regulated gene‐inducing activity was detected in some SLE plasma samples. Conclusion: The coordinate activation of IFNα‐induced genes is a characteristic of PBMCs from many SLE patients, supporting the hypothesis that IFNα is the predominant stimulus for IFIG expression in lupus.

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.
