1 Mice lacking neutrophil elastase are resistant to bleomycin-induced pulmonary fibrosis. Bleomycin elastase, neutrophil expressed Mus musculus
2 In neutrophil elastase-null mice, biochemical and morphological characteristics of pulmonary fibrosis were attenuated for at least 60 days after bleomycin administration despite a typical response to bleomycin as evidenced by assessment of indices of DNA and cell damage. Bleomycin elastase, neutrophil expressed Mus musculus
3 In neutrophil elastase-null mice, biochemical and morphological characteristics of pulmonary fibrosis were attenuated for at least 60 days after bleomycin administration despite a typical response to bleomycin as evidenced by assessment of indices of DNA and cell damage. Bleomycin elastase, neutrophil expressed Mus musculus
4 Neutrophil burden of bleomycin-treated wild-type and neutrophil elastase-null mice was comparable, and marked neutrophilic alveolitis was manifest in bleomycin-treated neutrophil elastase-null mice. Bleomycin elastase, neutrophil expressed Mus musculus
5 Neutrophil burden of bleomycin-treated wild-type and neutrophil elastase-null mice was comparable, and marked neutrophilic alveolitis was manifest in bleomycin-treated neutrophil elastase-null mice. Bleomycin elastase, neutrophil expressed Mus musculus
6 An absence of immunostaining for active transforming growth factor (TGF)-beta in lung tissue from bleomycin-treated neutrophil elastase-null mice suggested a defect in TGF-beta activation, which was confirmed by biochemical assessment of TGF-beta levels in bronchoalveolar lavage fluid and lung tissue. Bleomycin elastase, neutrophil expressed Mus musculus
