immune system
• mice exposed to a mild LPS challenge exhibit pulmonary mechanics phenotypes indicative of emphysema
|
• lung bronchoalveolar lavage fluid shows an increase in neutrophil, monocyte, lymphocyte and macrophage counts in 42 week old, but not 8 week old, mice
|
respiratory system
• lung bronchoalveolar lavage fluid shows an increase in neutrophil, monocyte, lymphocyte and macrophage counts in 42 week old, but not 8 week old, mice
|
• the alveolar ducts are enlarged after a mild LPS exposure
• 70 week old unchallenged mice show enlargement of the alveolar ducts
|
• the alveoli are enlarged after a mild LPS exposure
• 70 week old unchallenged mice show enlargement of the alveoli
|
• unchallenged aged mice develop spontaneous emphysema with early signs detectable at 35 weeks of age and clear emphysematous phenotype at 50 weeks of age
• mice exposed to a mild LPS challenge exhibit pulmonary mechanics phenotypes indicative of emphysema
|
• elastance is decreased in 50 week old mice
|
• mice on average have a 22% higher lung volume and higher total surface area after exposure to a mild LPS challenge
|
• mice exposed to a mild LPS challenge exhibit increased inspiratory capacity
|
• mice exposed to a mild lipopolysaccharide (LPS) challenge show increased lung compliance as indicated by a pressure-volume loop that is shifted up and to the left
• at 35 weeks of age, the pressue-volume loop shows increased compliance as evidenced by a shift upwards and the quasistatic compliance is increased, with larger differences at 50 weeks of age
|
homeostasis/metabolism
• lung bronchoalveolar lavage fluid shows an increase in elastase activity with age, with a 2.2-fold difference at 8 weeks and 5.7-fold difference at 42 weeks of age
