Endothelial selectin deficiency does not impair lung granulocyte accumulation. Granulocytes recovered by BAL (A) or enzymatic-digestion (B) of the lungs of mice following after IP-priming only (day 0) or after IT SRBC challenge were enumerated as described in the legend to Figure 1. Note the marked difference in scales between the two panels. Dark bars, wt mice; light bars, E-P- mice. Data represent mean ± SEM of six mice per group (days 0 and 4) or 11-12 mice per group (day 7) assayed individually in at least two experiments. *, p<0.05, ***, p<0.001, unpaired Student t test.
