CatC in lung secretions from patients with chronic inflammatory lung diseases dominated either by macrophages or by neutrophils. A, immunoblots of 30-fold concentrates of BALF from patients with histiocytosis X (HX), desquamative interstitial pneumonia (DIP), or sarcoidosis (SC) using anti-CatC antibody Ab1. B, immunoblots of 20-fold concentrates of sputum supernatants from patients with cystic fibrosis (CF7 to CF9) and from patients with neutrophilic asthma (A1 and A2). The S4 control was a supernatant of ionophore-activated neutrophils.
