Research Abstract |
Macrolides are well-known antimicrobial agent and has been reported to possess immunomodulating properties. The aim of the present study was to investigate the efficacy of macrolides as an inhibitor of lipopolysaccharide (LPS)-induced bone resorption via CD14. The mouse calbaria-derived bone cells was used in this study. LPS-induced expression of IL-1 alpha mRNA and production of IL-l, and Lipid A-induced production of the factor were all completely inhibited by treatment with erythromycin. Interestingly, LPS-induced formation of osteoclasts and stimulation of bone resorption in mouse calvarial cell culture were also inhibited by erythromycin treatment. These results suggest that erythromycin is a potent inhibitor of LPS-induced bone resorption in the cells. Based on these observations, Macrolides may prove to be an effective anti-inflammatory agent against LPS-stimulated periodontal destruction in periapical and periodontal diseases.
