However, the potential mechanisms remain to be elucidated. The present study aimed to investigate the effect of FBD-medicated serum (FBDS) on lipopolysaccharide (LPS)-induced inflammation in macrophages. In RAW264.7 macrophages and bone marrow-derived macrophages (BMDMs), FBDS treatment significantly inhibited the production of pro-inflammatory cytokines induced by LPS. In addition, it was indicated that FBDS treatment suppressed the activation of NF-kappaB and Smad2/Smad3 following LPS treatment. Furthermore, FBDS treatment decreased the expression of transforming growth factor-beta1 and chitinase-3-like protein 1. In conclusion, the results demonstrated that treatment with FBDS inhibited LPS-induced inflammation in RAW264.7 and BMDM cells. These data may improve understanding of the effect of FBD on anti-inflammation and help determine the mechanisms underlying the alleviation of PF via FBD.
