摘  要:目的研究辅助性T细胞(Th17)/调节性T细胞(Treg)平衡变化在HTLV-I相关性脊髓病/热带痉挛性截瘫(HAM/TSP)疾病中的意义。方法分别应用ELISA法和流式细胞技术检测HAM/TSP患者脑脊液(CSF)上清液中的IL-17、IL-10水平及外周血Th17,Treg细胞的百分率,并计算二者的比值。结果HAM/TSP患者CSF上清IL-17含量及外周血Th17细胞百分率分别为[(4.58±0.70)pg/ml、(2.00±0.64)%],较对照组[(0.76±0.17)pg/ml、(0.41±0.24)%]均有显著升高,差异具有统计学意义(t=5.581、6.11,P〈0.01);HAM/TSP患者CSF上清IL-10含量及外周血Treg细胞百分率分别为[(8.64±2.22)pg/ml、(3.56±0.55)%],较对照组[(17.79±3.08)pg/ml、(7.30±1.20)%]均有显著降低,差异具有统计学意义(t:6.368、7.49,P〈0.01),HAM/TSP和对照组外周血Th17/Treg细胞比例分别为0.55±0.10、0.06±0.03,两者比较差异具有统计学意义(t=12.11,P〈0.01)。结论Th17细胞及其效应分子IL-17在HAM/TSP患者体内均显著升高,Treg细胞及其效应分子IL-lO均较对照组显著降低,Th17/Treg细胞动态平衡的变化在HAM/TSP的发病机制中发挥一定的作用。Objective To investigate the imbalance of T helper 17 (Thl7) / CD4 ± CD25 ± regulatory cell (Treg) in HAM/TSP patients. Methods Enzyme linked immunosorbent assay (EL1SA) was performed to measure the levels of interleukin (IL-17) and IL-10 in CSF, and flow cytometry to determine the percentage of Thl7 and Treg ceils in peripheral blood of patients with HAM/TSP. Results There was a significant increase in the level of IL-17 [ (4. 58 ± 0. 70 ) pg/ml vs (0. 76 ± 0. 17 ) pg/ml, P 〈 0. 01 ] in CSF and the percentage of Thl7 cells [ (2.00 ± 0. 64) % vs (0.41 ± 0. 24) %, P 〈 0. 01 ], but a decrease in the level of IL-10 in CSF and the percentage of Treg cells in peripheral blood of patients with HAM/TSP compared with the control group. The ratio of Thl7/Treg cell (0. 55 ±0. 10 vs 0. 06 ±0. 03) in the peripheral blood of patients with HAM/TSP increased significantly compared with control group ( t = 12. 11, P 〈 0.01 ). Conclusions The imbalance between Thl7 and Treg cells may play an important role in the pathogenesis of the disease.
