Fig 5. Lung apoptotic macrophages are elevated after O3 exposure.

Fig 5

WT mice were exposed to either air or O3 (0.3 ppm for 72 h) and lungs were harvested either immediately or 1 or 3 days after cessation of O3 exposure. (A) Total macrophages, (B) Alveolar Macrophages, and (C) Interstitial macrophages assessed by flow cytometry. (D) Representative gating for apoptotic macrophages in a WT mouse studied 1 day after cessation of O3 exposure. (E) Early apoptotic interstitial macrophages and (F) late apoptotic interstitial macrophages in WT mice at various times after cessation of O3 exposure. Results are mean ± SEM for 4–6 mice per group. * p<0.05 versus air; # p<0.05 versus immediate post.
