Tannic acid has astringent properties, due to its capacity to form protein¨Cmacromolecular complexes, as well as antibacterial and antioxidant properties. However, little is known about its anti-inflammatory properties. Purpose: To evaluate the anti-inflammatory activity of gelatin tannate by quantifying the suppression of key molecules produced during inflammatory events in lipopolysaccharide (LPS)-stimulated human intestinal cells. Methods: Intercellular adhesion molecule-1 (ICAM-1) expression was determined by Western blot analysis; interleukin-8 (IL-8) and tumor necrosis factor-¦Á (TNF-¦Á) concentrations were measured by enzyme-linked immunosorbent assays in Caco-2 cells 24 hours after treatment with LPS (1 ¦Ìg/mL) in presence of different concentrations of gelatin tannate. Results: ICAM-1 is induced on a wide variety of cells by inflammatory stimuli such as LPS. Our results have shown gelatin tannate as a potent inhibitor of ICAM-1 expression in LPS-stimulated Caco-2 cells. IL-8 and TNF-¦Á are important inflammatory mediators, recruiting neutrophils and T-lymphocytes. Together with LPS, adding gelatin tannate at different concentrations induced a dose-dependent inhibition of IL-8 and TNF-¦Á released by Caco-2 cells. Conclusion: These results suggest that gelatin tannate exerts anti-inflammatory effects by inhibiting the specific cytokines and adhesion molecules involved in several inflammatory disorders. %K Caco-2 %K ICAM-1 %K IL-8 %K TNF-¦Á %U https://www.dovepress.com/gelatin-tannate-reduces-the-proinflammatory-effects-of-lipopolysacchar-peer-reviewed-article-CEG
