Time course of LPS-induced airway inflammation.

<p>Leukocytes were collected from the airway compartment by BAL at various timepoints up to 7 days (168h) after intratracheal instillation of 1μg LPS. The number of live cells was determined by trypan blue exclusion. Live cell counts are displayed for PBS control and LPS-exposed <i>Duoxa</i>^<i>-/-</i> (-/-) and <i>Duoxa</i>^<i>+/+</i> (+/+) mice as indicated. Data are shown as mean ± SEM for six mice in each group; * = p< 0.05 between LPS-treated and PBS-treated controls, # = p<0.05 between LPS-treated <i>Duoxa</i>^<i>+/+</i> and <i>Duoxa</i>^<i>-/-</i> mice.
