Fig. 1From: Lupus nephritis correlates with B cell interferon-β, anti-Smith, and anti-DNA: a retrospective studyFlow cytometry analysis of IFNβ+ naïve B cells. A–C Flow cytometry plots showing the sequential gating of IFNβ in naïve B cells based on the indicated cell surface markers in a representative SLE patient with high B cell IFNβ (A), a representative SLE patient with low B cell IFNβ (B), and a representative healthy control donor (C). D Bar graph showing the percentages of IFNβ+ naïve B cells in SLE patients and healthy controls (PB, plasmablasts/plasma cells, HC; healthy control) (data are mean ± SD; unpaired t-test)Back to article page
