Figure 5. The number of neutrophils infiltrated into the alveoli at Day 2 after LPS treatment was not significantly different between WT mice and Xb130 KO mice (A–C).

On the other hand, there was significantly higher number of macrophages infiltrated into the alveoli in Xb130 KO mice (B) (D). The neutrophils and macrophages were immunohistochemically stained with antibodies for Ly-6B2 and F4/80 antibodies, respectively. Scale Bars = 50 μm. *p < 0.05, WT = Wild type, KO = Xb130 knockout.
