gp91^phox-/y mice display neutrophil recruitment to the alveolar space. The gp91^phox-/y mice display increased neutrophil infiltration into the alveolar space as measured in the BALf within 1 h and 2 h of zymosan injection when compared to the WT mice (a, b), with no significant difference in total BAL cell count (c). There is higher cell surface expression of CD11b on neutrophils from the BAL 2 h after injection when compared to WT mice (d) (N = 4–10 from five independent experiments). *p ≤ 0.05, **p ≤ 0.01.
