Supplementary Figure 4From: Proteinase-3 as the major autoantigen of c-ANCA is strongly expressed in lung tissue of patients with Wegener's granulomatosisProteinase-3 mRNA expression in macrophages and endothelial cells in a Wegener's granulomatosis lung specimen. The macrophages are double-labeled with CD68 (red cells). The histomorphological appearance of the marked cell points to an endothelial cell (arrow) (magnification, 60 × 2.5).Back to article page
