Abstract
Oxidative stress and inflammation are involved in the development of obesity, type 2 diabetes and vascular complications. Systemic inflammation, as seen in obesity, is associated with high plasmatic levels of pro-inflammatory, pro-atherogenic and pro-thrombotic adipokines. Here we studied the effects of lyophilized cranberries (LCB) on the secretion and expression of PAI-1, IL-6, MCP-1 and leptin in mature 3T3-L1 adipocytes under baseline conditions and excessive inflammatory response elicitation by stimulation with H2O2. Our data demonstrated that LCB significantly reduced the expression and secretion of IL-6, MCP-1 and leptin, as well as suppressed the overexpression of PAI-1 induced by H2O2. Our findings suggested that LCB counteracted the stimulatory effect of H2O2 on secretion and expression of pro-inflammatory adipokines, implying a potential anti-inflammatory effect during the inflammatory process induced via oxidative stress in adipose tissue.
