Additional file 1 of Inhibition of effector B cells by ibrutinib in systemic sclerosis

Supplemental Figure 1. Cytokine production by B cells of healthy volunteers with ibrutinib treatment (n = 4). B cells of healthy volunteers were stimulated with CpG for 24 h and treated with DMSO (Control) or ibrutinib (10 μM). With a Legendplex assay, cytokine levels of IL-6, TNF-⍺, IFN-γ and IL-10 were determined in the culture supernatant. Bars represent mean. Error bars indicate SEM. * p < 0.05, ** p < 0.01, *** p < 0.001.
