中文摘要:
目的：比较类风湿关节炎和骨关节炎外周血T淋巴细胞在IL-12作用下诱导STAT4酪氨酸磷酸化水平的差异。
方法：2007年5月至2009年8月分离提纯20例类风湿关节炎患者[均为女性；年龄28～55岁, 平均(45.0±13.0)岁]和20例骨关节炎患者[均为女性；年龄55～75岁, 平均(67.0±9.6)岁]的外周血T淋巴细胞, 流式细胞仪进行T淋巴细胞纯度鉴定。用50 ng/ml IL-12分别作用0、10、30、60 min后, 提取蛋白进行浓度测量, 然后进行Western Blot检测, 经蛋白条带灰度扫描, 比较IL-12作用各时间点类风湿关节炎和骨关节炎T淋巴细胞STAT4酪氨酸磷酸化水平的差异。
结果：经过对外周血单核细胞的分离纯化, T细胞纯度达到91%以上；IL-12在对骨关节炎和类风湿关节炎T细胞作用30 min后达到活化峰值, 在各个时间点(10、30、60 min)类风湿关节炎外周血T淋巴细胞活化水平均高于骨关节炎。
结论：类风湿关节炎外周血T淋巴细胞在IL-12作用下STAT4异常活化。 |

ABSTRACT
Objective: To compare the levels of STAT4 tyrosine phosphorylation in peripheral T-lymphocytes induced by IL-12 in rheumatoid arthritis(RA) and osteoarthritis(OA).
Methods: From May 2007 to August 2009, peripheral blood mononuclear cells(PBMCs) were isolated from RA patients[RA group, all the cases were female, the age was from 28 to 55 years with an average of (45.0±13.0) years] and OA patients[OA group, all the cases also were female;the age was from 55 to 75 years with an average of (67.0±9.6) years]. The purity of T-lymphocytes from PBMCs was accredited by flow cytometry. The IL-12 of 50 ng/ml added in T-lymphocytes, the levels of STAT4 tyrosine phosphorylation were detected by western blot after different time intervals(0, 10, 30, 60 min).
Results: The purity of T-lymphocytes were above 91% through diremption and depuration for peripheral blood monouclear cells. The levels of STAT4 tyrosine phosphorylation in T-lymphocytes from RA induced by IL-12 were higher than that from OA in the different times(10, 30, 60 min);after 30 min, its levels from RA and OA achieved to crest value.
Conclusion: STAT4 in peripheral T-lymphocytes of rheumatoid arthritis was more easily to be activated than osteoarthritis. |
