斑秃患者外周血CD4+CD25+Foxp3调节性T细胞及T淋巴细胞亚群的测定

目的 研究斑秃患者外周血中CD4+CD25+调节性T细胞数量及CD4+、CD8+ T淋巴细胞亚群数量与斑秃疾病严重程度的关系。方法 对斑秃进行病情分组，以流式细胞仪检测17例重度、15例局限型斑秃患者和25例正常人对照者外周血中有功能活性的CD4+CD25+调节性T细胞（即CD4+CD25+ Foxp 3 T 细胞）在CD4+ T淋巴细胞中的比率，CD4+和CD8+占T淋巴细胞的比率。 结果 重度斑秃患者外周血中有功能活性的CD4+CD25+ Foxp 3 T细胞占CD4+ T细胞比率为0.54% ± 0.31%，显著低于正常人对照组（3.21% ± 0.76%）及局限型斑秃患者（2.71% ± 0.37%，P ＜ 0.001）；与正常人对照组比较，差异无统计学意义（P ＞ 0.05）。重度斑秃患者的CD4+占T淋巴细胞的比率为32.61% ± 3.48%，显著低于正常人对照组（43.0% ± 3.63%，P ＜ 0.001），而CD8+占T淋巴细胞的比率为40.96% ± 8.54%，显著高于正常人对照组（25.23% ± 2.14%，P ＜ 0.001）。局限型斑秃患者的此两项指标分别为41.25% ± 4.27%和26.6% ± 2.28%，与对照组差异无统计学意义（P ＞ 0.05）。重度斑秃患者的CD8+占T淋巴细胞的比率与CD4+CD25+ Foxp 3调节性 T 细胞占CD4+ T细胞的比率有负相关关系（r ＝ －0.94，P ＜ 0.001）。结论 重度斑秃可能与外周血中CD4+CD25+ T细胞数量的减少和功能活性的降低有关。     

银屑病患者外周血调节性T细胞的检测

目的 检测不同类型银屑病患者外周血中调节性T细胞（Treg）的水平。方法 用流式细胞仪和单克隆荧光抗体检测20例寻常性银屑病、15例脓疱性银屑病和10例红皮病性银屑病患者外周血中CD4+CD25bright调节性T细胞百分率，对寻常性银屑病患者中的10例进行了CD4+CD25hi-intCD127low/-调节性T细胞百分率的检测。结果 红皮病性银屑病组CD4+CD25bright调节性T细胞比例高于其他组（P < 0.01）；寻常性银屑病患者组CD4+CD25hi-intCD127low/-调节性T细胞在CD4+ T细胞中比例为4.39% ± 0.84%，正常人对照组为3.83% ± 1.68%，两组进行Mann-Whitney U检验，差异无统计学意义（P > 0.05）。结论 CD4+CD25bright调节性T细胞可能与红皮病性银屑病的发病有关。     

白癜风患者外周血CD4+CD25+调节性T细胞的检测

目的 检测不同病期白癜风患者外周血CD4+CD25+调节性T细胞水平,探讨其与白癜风发病的关系.方法 白癜风患者34例,进展期19例,稳定期15例.通过流式细胞仪对不同病期白癜风患者外周血CD4+、CD4+CD25+T细胞水平进行检测,并与20例正常人比较.结果 进展期患者外周血中CD4+CD25+调节性T细胞占外周血淋巴细胞的表达率低于正常对照组(P<0.05);稳定期患者与正常对照组比,差异无统计学意义(P＞0.05);进展期患者低于稳定期患者,差异有统计学意义(P<0.05).进展期患者CD4+CD25+调节性T细胞占外周血淋巴细胞表达率与皮损面积呈负相关(P<0.05),稳定期则无相关性(P＞0.05).进展期与稳定期患者CD4+CD25+调节性T细胞占外周血淋巴细胞水平与病程均无明显相关性(P＞0.05).结论 白癜风患者外周血中存在异常比例的cD4+CD25+调节性T细胞,可能与白癜风的发病有关.     

白癜风患者外周血CD4+CD25+调节性T细胞的检测

Objective To determine the level of peripheral CD4+CD25+ regulatory T lymphocytes in patients with vitiligo at different stages and to study its relationship with the development of vitiligo. Methods Blood samples were collected from 34 outpatients with vitiligo, including 19 cases of progressive vitiligo and 15 cases of stable vitiligo, as well as from 20 normal human controls. Flow cytometry was used to detect the levels of peripheral CD4+ and CD4+CD25+ T lymphocytes in these samples. Results Compared with the controls, the percentage of CD4+CD25+ regulatory T lymphoeytes in peripheral lymphocytes was significantly lower in patients with progressive vitiligo than those in patients with stable vitiligo and normal human con-trois [(2.43±0.30)% vs (3.49±0.39)% and (3.34±0.24)%, both P <0.05], but no significant difference was found between patients with stable vitiligo and normal human controls (P＞0.05). A significantly nega-tive correlation was observed between the percentage of CD4+CD25+ regulatory T lymphocytes and lesion area in patients with progressive vitiligo (r = -0.48, P <0.05), but not in patients with stable vitiligo (P ＞0.05). There was no significant correlation between the course of disease and the percentage of peripheral CD4+CD25+ regulatory T lymphocytes in patients with progressive vitiligo or stable vitiligo (both P ＞ 0.05). Conclusion There is an abnormal proportion of peripheral CD4+CD25+ regulatory T lymphocytes in patients with vitiligo, which may be related to the development of vitiligo.
