摘 要: | 摘要 目的 探讨特应性皮炎患者CD4+IL-10+调节性T细胞及其细胞因子的改变。方法 用流氏细胞仪直接免疫荧光法检测AD患者外周血CD4+IL-10+T细胞的绝对计数和百分率;用酶联免疫吸附试验检测外周血细胞因子IL-10、TGF-β的浓度。 结果AD患者CD4+IL-10+T细胞绝对计数为0.26+0.126×109/L,占CD4+T细胞的百分率是12.76+4.85%;而对照组CD4+IL-10+T细胞绝对计数为0.016+0.007×109/L,占CD4+T细胞的百分率是3.27+1.03%。经t检验,AD患者CD4+IL-10+T细胞绝对计数和百分率均高于对照组,有统计学差异(p <0.05)。 AD患者外周血IL-10浓度为126.59+59.46 pg/ml,高于正常对照组(31.47+10.96 pg/ml),经t检验,有统计学差异(p<0.05)。AD患者外周血TGF-β浓度为407.23+155.88 pg/ml,高于正常对照组(359.47+99.21 pg/ml),但经t检验,没有统计学差异(p>0.05)。CD4+IL-10+T细胞绝对计数、百分率均与外周血IL-10浓度呈正相关,有统计学意义(r=0.47,r=0.65, p <0.05);而与外周血TGF-β无统计学相关性(r=0.15,r=0.21 , p >0.05)。结论 IL-10可能是Trl发挥功能的主要因子,通过下调由Thl和Th2细胞介导的炎症反应过程,参与免疫调节。

Change of CD4+IL-10+regulatory T Cell in Atopic Dermatitis patients |

Abstract: | Abstract: Objective To explore the change of CD4 + IL-10 + regulatory T cells and cytokine in atopic dermatitis. Methods The direct immunofluorescence assay was used to detect CD4+ IL-10 +Tcell by flow cytometry. ELISA was used to assay IL-10 and TGF-βin peripheral blood. Results The absolute count of CD4 + IL-10 + T cells is 0.26 + 0.126×109 / L, and the percentage is 12.76 + 4.85% in AD patients . They are higher than in control group(0.016 + 0.007×109 / L; 3.27 + 1.03%). There ere statistically significant (p < 0.05). The peripheral blood IL-10 concentration in AD patients is 126.59+ 59.46 pg/ml, higher than normal control group (31.47 +10.96 pg/ml) (p < 0.05). The peripheral blood TGF-βconcentration in AD patients is 407.23 + 155.88 pg/ml, higher than normal control group (359.47 + 99.21 pg/ml) (p > 0.05). There are statistically positive correlation between absolute and percentage of CD4 + IL-10 + T cell and IL-10 concentration (r = 0.47, r = 0.65, p < 0.05). Whereas There are no statistically correlation between absolute and percentage of CD4 + IL-10 + T cell and TGF-βconcentration (r = 0.15, r = 0.21, p > 0.05). Conclusion IL-10 is the main functional f actor of Trl. It can involved in immune adjustment by cutting inflammation process mediated by Thl and Th2 cell. |
