Representative heat map demonstrating anti-IFN-α, -IFNAR, and -IFN-ω mAb effects on healthy donor PBMC stimulated with serum from 1 SLE patient. Lane 1: SLE patient serum only; Lane 2: SLE patient serum plus reference antibody; Lane 3: SLE patient serum plus 10 μg/mL anti-IFN-ω mAb; Lanes 4–6: SLE patient serum plus increasing concentrations of anti-IFN-α mAb (0.1, 1, and 10 μg/mL); Lane 7: SLE patient serum plus 10 μg/mL anti-IFNAR mAb. Color represents relative neutralization (inhibition) of overexpression of individual genes upregulated by soluble mediators in the serum of an SLE patient. The red color represents no neutralization, and green represents neutralization of overexpression of individual genes. IFN = interferon; IFNAR = interferon associated receptor; PBMC = peripheral blood mononuclear cells; SLE = systemic lupus erythematosus.
