Abstract
|
|
|
|
Obesity is associated with inflammatory status and linked with metabolic syndrome. Interaction between adipocytes and macrophages aggravates inflammation and leads to insulin resistance in adipocytes. Resveratrol improved reportedly obesity-related inflammatory responses, but the effects of resveratrol on the production of inflammatory mediators and glucose metabolism in inflamed adipose tissue is not completely known. In this study, we investigated the effects of resveratrol on inflammatory change and insulin resistance in the coculture of hypertrophied 3T3-L1 adipocytes and RAW 264.7 macrophages. Resveratrol decreased nitric oxide production and the expression of interleukin (IL)-6, IL-1β, tumor necrosis factor-α, inducible nitric oxide synthesis, and cyclooxygenase-2 in the coculture. Resveratrol increased glucose uptake by stimulating the phosphorylation of IRS-1 and AKT in the coculture. These results support that resveratrol have beneficial effect on inflammation and insulin resistance in inflamed adipose tissue.
