immune system
• mice administered doxycycline (Dox) exhibit an increase in IFN-gamma production in the lungs
|
• mice treated with Dox show pulmonary inflammation, with infiltration of mononuclear cells in the alveolar wall and general interstitium, indicating interstitial pneumonia
• however, mice treated with Dox do not exhibit emphysema, swelled alveolar macrophages, hyaline membranes, or proteinaceous debris, and show no evidence of increased lung volumes or cardiomegaly

• mean alveolar chord length is lower than in wild-type mice
