摘要
目的:研究Th17(IL-17A)在肝细胞癌发生发展中的作用,尤其与乙肝病毒感染的关系。方法:收集39例原发性肝细胞癌患者的癌与非癌组织,应用流式细胞微球阵列术(CBA)检测IL-2、IL-4、IL-6、IFN-γ、IL-17A细胞因子水平,并与患者临床资料进行统计比较分析。结果:肝癌组织中IL-2、IL-4、IFN-γ表达水平好[分别为(4.61±0.28)、(3.37±0.58)、(3.08±1.08)pg/ml]显著低于非癌组织[分别为(5.57±0.59)、(3.77±0.70)、(3.69±1.20)pg/ml],而IL-6、IL-17A水平[分别为(280.09±254.68)、(2.66±1.66)pg/ml]显著高于非癌组织[分别为(6.58±1.92)、(1.49±0.98)pg/ml],同时无论癌组织还是非癌组织,高乙肝病毒载量(>1 000 U/ml)的组织IL-17A的表达[(3.45±1.86)pg/ml]显著高于低病毒载量(<1 000U/ml)的组织[(1.97±1.16)pg/ml]。结论:Th17细胞分泌的细胞因子IL-17A在肝癌组织中高表达,IL-2、IL-4和IFN-γ可能抑制其表达,而IL-6可能促进其表达;乙肝病毒感染有可能促进Th17的表达,从而降低患者的预后。
Objective:To explore the significance of Th17 in hepatocellular carcinoma,expecially with HBV infection. Methods: Cytometric bead array( CBA) was employed to detect 5 cytokines( IL-2,IL-4,IL-6,IFN-γ,IL-17A) from 39 tumor and non-tumor tissues of HCC and combined clinical data for comparative statistic analysis. Results: The expression of IL-2,IL-4,IFN-γ in liver cancer tissue[(4. 61 ± 0. 28),(3. 37 ± 0. 58),(3. 08 ± 1. 08)pg /ml,respectively]was significant lower than non-cancer tissue[(5. 57 ± 0. 59),(3. 77 ± 0. 70),(3. 69 ± 1. 20) pg / ml,respectively]. Otherwise,the expression of IL-6,IL-17 A in cancer tissue[(280. 09 ± 254. 68),(2. 66 ± 1. 66)pg/ml,respectively]was higher than non-cancer[(6. 58 ± 1. 92),(1. 49 ± 0. 98)pg/ml,respectively]. And,whatever cancer or non-cancer tissue,the expression of IL-17 A in tissue[(3. 45 ± 1. 86) pg / ml]with high HBV load( 〉1000 U / ml) was significant higher than tissue with low HBV load[(1. 97 ± 1. 16) pg / ml]. Conclusion: IL-17 A was highly expressed in HCC,and IL-2,IL-4,IFN-γ may inhibit its expression,and IL-6 may promote it. Hepatitis B virus infection may promote Th17 expression,thereby reducing patient's prognosis.
