Inhibitory activity of the white wine compounds, tyrosol and caffeic acid, on lipopolysaccharide-induced tumor necrosis factor-alpha release in human peripheral blood mononuclear cells

摘要

abstract_textpThe objective of this study was to assess whether tyrosol and caffeic acid are able to inhibit lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-alpha release. TNF is one of the most important cytokines involved in inflammatory reactions. The results show that both tyrosol and caffeic acid are able to inhibit LPS-induced TNF-alpha release from human monocytes, even at low doses. Their mechanisms of action are discussed and we conclude that high doses of the two compounds are not required to achieve effective inhibition of inflammatory reactions due to TNF-alpha release./p/abstract_text
