摘要 目的研究胰岛素抵抗的慢性丙型肝炎患者外周血辅助性T(Th)17淋巴细胞和自然杀伤性T(NKT)细胞数量和功能的变化。方法筛选52例慢性丙型肝炎患者(其中合并胰岛素抵抗26例),采用流式细胞仪检测患者外周血Th17和NKT细胞频率,细胞内染色技术检测细胞内白细胞介素4(IL-4)和IFN-γ染色阳性的NKT细胞的比例,ELISA法检测患者白细胞介素17(IL-17)的水平。数据行t检验。结果胰岛素抵抗的慢性丙型肝炎患者外周血Th17细胞频率、IL-17水平和细胞内IFN-γ阳性的NKT细胞的比例明显高于慢性丙型肝炎患者[分别为(6.60±1.70)%与(4.52±1.05)%,t=5.205,P<0.01;(180.0±35.6)与(82.0±17.0)pg/mL,t=12.674,P<0.01;(39.5±9.1)%与(32.0±6.5)%,t=3.420,P<0.01];而NKT细胞频率明显降低[(0.42±0.09)%与(0.62±0.14)%,t=9.325,P<0.01]。胰岛素抵抗指数(HOMA-IR)≥4患者组Th17细胞频率、IL-17水平和细胞内IFN-γ阳性的NKT细胞比例明显高于HOMA-IR<4患者[分别为(7.35±1.80)%与(5.82±1.47)%,t=3.292,P<0.01;(243.3±61.2)与(144.7±37.5)pg/mL,t=6.938,P<0.01;(44.3±10.2)%与(34.7±7.5)%,t=3.866,P<0.01];NKT细胞频率明显下降[(0.33±0.08)%与(0.52±0.12)%,t=6.718,P<0.01]。结论随着胰岛素抵抗程度加重,慢性丙型肝炎患者外周血Th17细胞频率升高,分泌IL-17增加;NKT细胞频率减少,分泌IFN-γ增加,导致炎症反应向Th1漂移。
