Supplementary Figure 5From: Proteinase-3 as the major autoantigen of c-ANCA is strongly expressed in lung tissue of patients with Wegener's granulomatosisThe proteinase-3 (PR-3) protein is expressed in pneumocytes type I in Wegener's granulomatosis tissue (arrows). The expression of PR-3 protein was detected by immunohistological staining with WGM2 antibodies, and the pneumocytes type I were detected by double-labeling with fluorescent lectins of Bauhinia purpurea (magnification, 60 × 2.5).Back to article page
