Isoliquiritigenin suppressed inflammation through Mincle-dependent mechanism in BMDM cells. (A) In the Mincle recovery experiment, we used TDB to upregulate Mincle in ISL-treated inflammatory BMDM. The results showed that the protein level of Mincle (B), iNOS (C), phosphorylated Syk (D) and phosphorylated NF-kappa B (E) were significantly increased in ISL-treated inflammatory BMDM, suggesting ISL inhibits inflammation by suppressing Mincle; Overexpression of Mincle by administration of TDB, upregulated the expression (F–I) and secretion (J–L) of IL-1β, IL-6 and TNF-α and MCP-1 in ISL-treated inflammatory BMDM.
