Inflammation serves as the initial pathologic step of cardiovascular diseases including atherosclerosis. Resveratrol possesses many pharmacological properties including antioxidant, cardioprotective and anti-cancer effects. In this study, we investigate the anti-inflammatory effect and mechanisms of resveratrol in an atherosclerotic rabbit model.


Rabbit were assigned to six groups (n = 10 each): control, high fat diet group, resveratrol low, medium and high dose groups, resveratrol pretreatment group. The serum tumor necrosis factor-α (TNF- α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) were analyzed by Enzyme-linked immuno sorbent assay(ELISA). Phosphorylation levels of mitogen-activated protein kinases (MAPKs) cascades and NF-κB were determined by Western blot.


Compared with the control group, the expression of serum inflammatory factors IL-1β, IL-6, TNF-α were increased in high-fat group (all P < 0.05). Compared with high-fat group, the expressions of IL-6, IL-1β, TNF-α were significantly reduced in resveratrol low, medium, high dose groups and resveratrol pretreatment group (all P < 0.01), and this effect is dose-dependent. In addition, the NF-κB, p38MAPK, JNK, ERK1/2 protein phosphorylation in high-fat group were significantly upregulated compared with control group (P < 0.05), which (except ERK1/2 phosphorylation level) were significantly downregulated in resveratrol treatment group and resveratrol pretreatment group.


This study indicates that resveratrol reduces serum inflammatory cytokines in this atherosclerotic rabbit model via down-regulation phosphorylation of NF-κB, and MAPKs signaling, which might serve as the anti-inflammatory molecular basis of resveratrol.
