Neutrophil extracellular trap (NET) release stimulated by phorbol 12-myristate 13-acetate (PMA) or by a pool of plasma from healthy control subjects (HCs), patients with inactive Behçet’s disease (iBD), and patients with active Behçet’s disease (aBD). Immunofluorescence photomicroscopy illustrates the effect of plasma from patients with Behçet’s disease (BD) in normal and BD neutrophils. White bars indicate scale = 50 μm; green = histone H2A/B; red = human neutrophil elastase; blue = chromatin
