Figure 5.

Relative expression of mRNAs and median fold changes (horizontal bars) of (a) type I IFN-α subtypes, (b) other members of the type I IFNs and IFN-α receptors, and (c) TNF-α, IFN-γ, and IFN-γ receptors in WB of SLE patients compared with healthy controls (P ≤ .05 for all). Averages of relative mRNA levels of these cytokines and their receptors in WB from 24 healthy donors were scaled to 1 based on TaqMan QRT-PCR assays. IFN = interferon; QRT-PCR = quantitative real-time reverse transcriptase polymerase chain reaction; SLE = systemic lupus erythematosus; TNF-α = tumor necrosis factor.
