PURPOSE. Resveratrol is known as one of the antioxidant polyphenols contained in red wine and grape skin. The purpose of the present study was to investigate the role of resveratrol in ocular inflammation in endotoxin-induced uveitis (EIU). METHODS. EIU was induced in male C57/B6 mice at the age of 6 weeks by a single intraperitoneal injection of lipopolysaccharide (LPS). Animals had received oral supplementation of resveratrol at the doses of 5, 50, 100, or 200 mg/kg for 5 days until LPS injection. Twenty-four hours after LPS administration, leukocyte adhesion to the retinal vasculature was examined with a concanavalin A lectin perfusion-labeling technique. Retinal and retinal pigment epithelium (RPE)-choroidal levels of intercellular adhesion molecule (ICAM)-1, monocyte chemotactic protein (MCP)-1, and 8-hydroxy-2κ-deoxyguanosine (8-OHdG) and nuclear translocation of nuclear factor (NF)-κB p65 were evaluated by enzyme-linked immunosorbent assay. Retinal and RPE-choroidal activities of silent information regulator two ortholog (SIRT) 1 were measured by deacetylase fluorometric assay. RESULTS. Resveratrol pretreatment led to significant and dosedependent suppression of leukocyte adhesion to retinal vessels of EIU mice compared with vehicle application. Protein levels of MCP-1 and ICAM-1 in the retina and the RPE-choroid of EIU animals were significantly reduced by resveratrol administration. Importantly, resveratrol-treated animals showed significant decline of retinal 8-OHdG generation and nuclear NF-κB P65 translocation, both of which were upregulated after EIU induction. RPE-choroidal SIRT1 activity, reduced in EIU animals, was significantly augmented by treatment with resveratrol. CONCLUSIONS. Resveratrol prevented EIU-associated cellular and molecular inflammatory responses by inhibiting oxidative damage and redox-sensitive NF-κB activation.
