NF157 blocked M1 polarization of macrophages in LPS-treated mice.

<p>(<b>A</b>, <b>B</b>) Peritoneal and splenic macrophages were isolated from mice 24 h after LPS injection, and analyzed by flow cytometry for the expression of CCR7. Each value represents the mean ± SE. A significant difference between the positive control group (LPS alone) and the indicated group is indicated by **(p<0.01).
