Acrolein exposure attenuates allergic airway inflammation in OVA-sensitized and challenged mice. C57BL/6 mice were sensitized and exposed as shown in Figure 1. Bronchoalveolar lavage fluid (BALF) was collected on day 18 ( A,B ) or 14 (6 hrs after OVA challenge; C,D ) for enumeration of total cells ( A, C ) and differential cell counts ( B,D ). Results are expressed as mean ± SEM (n = 3-10/group) (*, p < 0.05).
