http://ncercc.co.uk/theory/resilience/ Royal jelly (RJ) is known as a functional food for its diverse health-beneficial properties and complicated chemical compositions. Trans-10-hydroxy-2-decenoic acid (10-HDA) is the exclusive lipid component in RJ. In the present study, the in vitro anti-inflammatory effect of 10-HDA in LTA (Lipoteichoic acid from Staphylococcus aureus) induced RAW 264.7 macrophages are evaluated. The results showed that 10-HDA had potent, dose-dependent inhibitory effects on the release of major inflammatory mediators and NO. Several key inflammatory genes, including IL-1β, IL-6, MCP-1 and COX-2 have also been suppressed by 10-HDA. Furthermore, the effects of 10-HDA on LTA-induced pulmonary damage were also examined in mice. It was found that the administration of 10-HDA (100 mg/kg) can provide protective effects by attenuating lung histopathological changes and modulating the secretion of LTA-stimulated inflammatory cytokines in mice, such as IL-10, MCP-1 and TNF-α. Conclusively, the results reveal the potent anti-inflammatory properties of 10-HDA and provide biological information for the future application.(Journal of Functional Foods.
