摘 要:
摘 要:酒精性肝病(alcoholic liver disease, ALD)的发生发展过程与体内多种细胞因子有关,尤其是肿瘤坏死因子-a(tumor necrosis factor-a, TNF-a)和转化生长因子-b(transforming growth factor-b, TGF-b)在调节肝细胞的凋亡过程中具有重要作用。TNF-a可引起肝细胞凋亡与炎症反应等,抗TNF-a治疗能明显减轻酒精引起的肝损害; TGF-b具有增加细胞外基质的合成和抑制细胞外基质降解的作用,TGF-b1升高与肝纤维化密切相关。细胞因子可能是防治酒精性肝病的有效分子靶点。

Abstract:
Abstract: Cytokines, especially tumor necrosis factor-a (TNF-a) and transforming growth factor-b(TGF-b), play an important role in the mechanisms in the pathogenesis of alcoholic liver disease (ALD), such as steatohepatitis, fibrosis, and cirrhosis. TNF- a and TGF-b are involved in the apoptotic liver cell death. TNF-a also takes part in the inflammation related to ALD. TNF-a antibody can distinctly alleviate alcohol-induced liver injury. TGF-b can increase extracellular matrix synthesis and inhibit its degradation; TGF-b1 is intimately related to the alcoholic liver fibrosis. Cytokines are promising targets for preventing and treatment of the ALD.
