Leukocyte Production of Inflammatory Mediators Is Inhibited by the Antioxidants Phloretin, Silymarin, Hesperetin, and Resveratrol
Production of the anti-inflammatory factors IL-1Ra and IL-10. Human PBMCs were cultured for 18 hrs in media alone, stimulated with Aa Y4 LPS (1 μg/mL), or treated with Phloretin, Silymarin, Hesperetin, or Resveratrol at a concentration of M for 2 hrs prior to LPS challenge. After 18 hrs, the concentrations of (a) IL-1Ra and (b) IL-10 were assayed by cytometric bead array. ANOVA was performed for statistical analysis, indicating statistical significance versus LPS, independent donors.
