Abstract

To assess the clinical utility of the ratio of CD4+CD25+CD127 regulatory T cells (Tregs) in subjects at high risk of HCC, investigate the relationship between the percentage of Tregs and the expression of transforming growth factor (TGF)-β1 and interleukin (IL)-10 in patients with hepatocellular carcinoma before and after treatment. Peripheral venous blood was collected from patients with liver cancer before and after treatment. The proportion of CD4+CD25+CD127 Tregs was detected by flow cytometry. The levels of TGF-β1 and IL-10 in serum were detected by enzyme-linked immunosorbent assay, and were compared with healthy subjects as a control group. The proportion of CD4+CD25+CD127 to CD4+T lymphocytes in patients with hepatocellular carcinoma was significantly higher than that in healthy controls (). The proportion of CD4+CD25+CD127Tregs, whose AUC of ROC curve was 0.917, could effectively separate the HCC patients from the healthy subjects with a diagnostic sensitivity of 90%, specificity of 80%. The proportion of CD4+CD25+CD127 to CD4+T lymphocytes and the levels of TGF-β1 and IL-10 in patients with hepatocellular carcinoma after the operation and chemotherapy were significantly lower than those before treatment (P<0.05).The proportion of CD4+CD25+CD127Tregs was positively correlated with the concentrations of TGF-β1 and IL-10 before and after treatment of primary liver cancer (P<0.05). CD4+CD25+CD127Tregs may be a significant predictor of HCC biopsy outcome and play an inhibitory role on effector T cells by regulating cytokines.

摘要

为了评估 CD4+CD25+CD127 调节性 T 细胞(Tregs)在 HCC 高危人群中的临床应用价值,我们研究了肝癌患者治疗前后 Tregs 比例与转化生长因子(TGF)-β1 和白细胞介素(IL)-10 表达之间的关系。采集肝癌患者治疗前后的外周静脉血,采用流式细胞术检测 CD4+CD25+CD127 Tregs 的比例,酶联免疫吸附试验(ELISA)检测血清中 TGF-β1 和 IL-10 的水平,并与健康对照组进行比较。结果显示,肝癌患者 CD4+CD25+CD127 对 CD4+T 淋巴细胞的比例明显高于健康对照组()。CD4+CD25+CD127Tregs 比例的 AUC 为 0.917,可有效区分 HCC 患者与健康对照者,诊断敏感度为 90%,特异度为 80%。肝癌患者手术后和化疗后的 CD4+CD25+CD127Tregs 比例以及 TGF-β1 和 IL-10 水平明显低于治疗前(P<0.05)。CD4+CD25+CD127Tregs 比例与原发性肝癌治疗前后 TGF-β1 和 IL-10 的浓度呈正相关(P<0.05)。CD4+CD25+CD127Tregs 可能是 HCC 活检结果的重要预测指标,通过调节细胞因子对效应 T 细胞发挥抑制作用。
