Peak airway pressures measured at various times during the experimental protocol for mice subjected to either 1 hr of left lung warm ischemia and 4 hr of reperfusion (-IR, n = 12/grp for C57BL/6 and <i>Tlr4</i>^<i>-/-</i>; n=10 for <i>Myd88</i>^<i>-/-</i>) or sham thoracotomy and 5 hr of mechanical ventilation (-Sham, n=4/grp).

<p>*p ≤ 0.05 between <i>MyD88</i>^<i>-/-</i> and <i>Tlr4</i>^<i>-/-</i> mice subjected to sham surgery at specific times.
