Figure 6. Administration of mOVA affects the acute effect of poly(I:C) on cell recruitment in BAL.

Mice received one intranasal injection of PBS, mOVA (100 µg), poly(I:C) (20 µg) or mOVA + poly(I:C). BAL fluids and lungs were collected 16 h later. (A) Total and differential cell counts in the BAL were assessed by MGG coloration. Data are expressed as the mean ± SEM from 3 independent experiments including four mice per group. *: p<0.05 versus cells in medium alone; ≠: p<0.05 versus cells with poly(I:C). (B) Representative hematoxylin and eosin staining of lung sections in the four groups of mice. Magnification: ×300.
