From: Lung Inflammation in alpha-1-antitrypsin deficient individuals with normal lung function
Protease-antiprotease imbalance in the epithelial lining fluid (ELF) of alpha1- antitrypsin deficient individuals. Bronchoalveolar lavage was performed in control subjects (N = 14), and alpha1- antitrypsin deficient (N = 22) individuals as described in the methods. A The concentrations of alpha1- antitrypsin, B Alpha1- antitrypsin:anti-neutrophil elastase capacity (ANEC), C neutrophil elastase (NE), and D protease 3 (PR3) were measured by ELISA and expressed as levels of analyte in the ELF. **P < 0.005, ****P < 0.00005
