Fig. 1: LPS challenge initiates blood myeloid cell expansion and lung leukocyte trafficking.

A Blood neutrophil and (B) monocyte numbers were quantified in hβcTg mice treated with LPS (1 or 10 μg). C BAL neutrophil and (D) macrophage numbers were also quantified after LPS challenge (E) MPO activity was quantified in lung tissue as a marker for tissue neutrophil infiltration. F Total protein levels in BAL-fluid was also measured. n = 5–6; data are Mean ± SE; *p < 0.05, one-way ANOVA.
