Abstract

Resveratrol (Res) is a natural compound that possesses anti‑inflammatory properties. However, the protective molecular mechanisms of Res against lipopolysaccharide (LPS)‑induced inflammation have not been fully studied. In the present study, RAW264.7 cells were stimulated with LPS in the presence or absence of Res, and the subsequent modifications to the LPS‑induced signaling pathways caused by Res treatment were examined. It was identified that Res decreased the mRNA levels of Toll‑like receptor 4 (TLR4), myeloid differentiation primary response protein MyD88, TIR domain‑containing adapter molecule 2, which suggested that Res may inhibit the activation of the TLR4 signaling pathway. It suppressed the expression levels of total and phosphorylated TLR4, NF‑κB inhibitor, p38 mitogen‑activated protein kinase (MAPK), c‑Jun N‑terminal kinase, extracellular signal‑regulated kinase 1/2 and interferon (IFN) regulatory factor 3 (IRF3) proteins. Following treatment with Res or specific inhibitors, the production of pro‑inflammatory mediators including tumor necrosis factor‑α, interleukin (IL)‑6, IL‑8 and IFN‑β were decreased and the expression of anti‑inflammatory mediator IL‑10 was increased. These results suggested that Res may inhibit the signaling cascades of NF‑κB, MAPKs and IRF3, which modulate pro‑inflammatory cytokines. In conclusion, Res exhibited a therapeutic effect on LPS‑induced inflammation through suppression of the TLR4‑NF‑κB/MAPKs/IRF3 signaling cascades.
