Following the earlier observation that there was no change in neutrophil frequency between SFB(−) and (+) Rag−/− mice at 18 h post infection, we found that there may be a very slight trend but no significant change in either the inflammatory (CD62L−CD18+) or pro-resolution (CD62L+CD18−) neutrophil phenotype at 18 h post infection (Figure 7C). This evidence concerns the gene ITGB2 and infection.
