Protective effect of 2,2,2-trichloroethanol on peptidoglycan-induced inflammation in murine macrophages

The aim of this study was to investigate the effect of 2,2,2-trichloroethanol on peptidoglycan-induced murine macrophages inflammation. The effect of 2,2,2-trichloroethanol on the production of TNF-α and IL-6 by murine peritoneal macrophages with peptidoglycan-stimulation were investigated. Also, RAW264.7 macrophages transfected with a NF-κB luciferase reporter plasmid with the stimulation of peptidoglycan were used to test the effect of 2,2,2-trichloroethanol on NF-κB activity. Flow cytometry and Western blotting were used to check the expression levels of toll-like receptor 2 on treated RAW264.7 macrophages. 2,2,2-Trichloroethanol decreased the unregulated levels of IL-6 and TNF-α produced by the peritoneal macrophages stimulation with peptidoglycan. The NF-κB activities of the RAW264.7 macrophages stimulated by peptidoglycan were decreased. 2,2,2-Trichloroethanol decreased the peptidoglycan-induced murine macrophage inflammation response. Key words: 2,2,2-Trichloroethanol, peptidoglycan, inflammation, macrophage.
