International immunopharmacology, 2004•ElsevierResveratrol, a polyphenol compound found in grapes and red wines, is a prominent anti-
cancer agent. In this study, we demonstrate that resveratrol enhanced TNF-α, IL-12 and IL-
1β production from LPS activated phorbol myristate acetate (PMA) differentiated THP-1
human macrophages. Expression of CD86 on macrophages was enhanced by resveratrol
alone and with LPS. When macrophages were primed with IFN-γ, resveratrol suppressed
the expression of HLA-ABC, HLA-DR, CD80, CD86 and inhibited production of TNF-α, IL-12 …

When macrophages were primed with IFN-γ, resveratrol suppressed the expression of HLA-ABC, HLA-DR, CD80, CD86 and inhibited production of TNF-α, IL-12, IL-6 and IL-1β induced by LPS. The differential impact of resveratrol on expression of CD14 might be correlated with differential response of macrophages to LPS with or without IFN-γ priming.
