The liver X receptor agonist T0901317 reduces the inflammation of alveolar epithelial cells induced by polyhexamethylene guanidine through inhibition of the NFκB signaling pathway

BACKGROUND: As a kind of disinfectant, polyhexamethylene guanidine (PHMG) can cause pulmonary inflammation. In addition to liver X receptors (LXRs) playing an important role in cholesterol and lipid metabolism, it has also been found to be involved in inflammation in recent years. This article explores the role of LXRs agonist T0901317 in the inflammation of alveolar epithelial cells induced by PHMG.
METHODS: The A549 human alveolar basal epithelial cell line was exposed to PHMG, T0901317, or the nuclear factor (NF)κB inhibitor BAY11-7082. The cell survival rate was used to determine the cytotoxicity of PHMG and T0901317 to A549 cells. Western blot analysis was used to determine the expression of proteins related to the LXRs and the NFκB signaling pathway. Enzyme-linked immunosorbent assay (ELISA) was conducted to examine the expression of inflammatory cytokines such as interleukin (IL)-8 and interleukin (IL)-6.
RESULTS: Incubation of A549 cells with PHMG decreased the expression of LXRs-related proteins, reduced the expression of cellular IκB, increased the expression of nuclear NFκB, and increased the levels of the inflammatory cytokineIL-8 and IL-6. However, pretreatment with the LXR agonist T0901317 partially reversed the effects of PHMG. The effects of T0901317on NFκB signaling pathway was similar to that observed with the NFκB inhibitor BAY11-7082.
CONCLUSIONS: The LXRs agonist T0901317 may reduce the inflammation of alveolar epithelial cells induced by PHMG by inhibiting the NFκB signaling pathway.
