The accumulation/deposition of fat within the liver is essential for diagnosis of NAFLD and might be associated with alterations in the hepatic and systemic inflammatory state. Although it is still unclear if each histological entity represents a different disease or rather steps of the same disease, inflammatory processes in NAFLD might influence its pathophysiology and prognosis. In particular, non-alcoholic steatohepatitis (the most inflamed condition in NAFLDs, which more frequently evolves towards chronic and serious liver diseases) is characterized by a marked activation of inflammatory cells and the upregulation of several soluble inflammatory mediators. Among several mediators, cytokines and chemokines might play a pivotal active role in NAFLD and are considered as potential therapeutic targets. In this review, we will update evidence from both basic research and clinical studies on the potential role of cytokines and chemokines in the pathophysiology of NAFLD.展开更多

Methods: With carriers of cationic liposomes, decoy-ODNs were transfected into pMΦ cells of rats. Then the inhibiting effects of the decoy-ODNs on tumor necrosis factor α (TNFα), interleukin-6 (IL-6) and IL-10 were analyzed. Results: Decoy-ODNs could decrease the expression of TNFα and IL-6 in dose-dependent fashion but had weaker inhibiting effect on IL-10. Conclusions: Decoy-ODNs targeting NF-κB can decrease the expression of inflammatory mediators in pMΦ cells from rats.展开更多
