文题释义:
CD4+CD25+调节性T细胞:
是一类最近才被人们认识的免疫调节细胞,起源于胸腺,发挥抑制性免疫调节作用,持续性表达IL-2Rα链(CD25),具有免疫抑制性和免疫无能性两大特征,在自身免疫性疾病的治疗、肿瘤的免疫治疗以及移植耐受的诱导等方面具有潜在的应用价值。
白细胞介素17:是T 细胞诱导的炎症反应的早期启动因子,可以通过促进释放前炎性细胞因子来放大炎症反应。白细胞介素17与受体结合后,可通过MAP 激酶途径和核转录因子κB途径发挥其生物学作用。

 

摘要
背景:
骨髓间充质干细胞具有自我更新和分化能力,能够迁移到组织损伤部位进行组织修复,在多种疾病治疗中被广泛应用。
目的:探讨骨髓间充质干细胞移植对骨关节炎大鼠的治疗作用。
方法:将36只Wistar大鼠随机分为移植组、模型组和对照组,移植组在建立骨关节炎模型后经尾静脉注射骨髓间充质干细胞(5×107/kg),模型组在建模后经尾静脉注射等量的生理盐水,对照组不予任何处理。各组大鼠于移植治疗后4周评定关节炎指数、关节肿胀度,检测脾脏CD4+CD25+调节性T细胞水平以及血清白细胞介素17、肿瘤坏死因子α、转化生长因子β1水平。
结果与结论:①模型组大鼠关节炎指数明显高于对照组(P < 0.05),移植组大鼠关节炎指数明显低于模型组(P < 0.05);②模型组大鼠后肢关节肿胀度明显高于对照组(P < 0.05),移植组大鼠后肢关节肿胀度明显低于模型组(P < 0.05);③模型组大鼠脾脏CD4+CD25+调节性T细胞水平明显低于对照组(P < 0.05);移植组大鼠脾脏CD4+CD25+调节性T细胞水平明显高于模型组和对照组(P < 0.05);④模型组大鼠血清白细胞介素17、肿瘤坏死因子α水平明显高于对照组(P < 0.05);移植组大鼠血清白细胞介素17、肿瘤坏死因子α水平明显低于模型组(P < 0.05),移植组大鼠血清白细胞介素17、肿瘤坏死因子α水平高于对照组(P < 0.05);⑤模型组大鼠血清转化生长因子β1水平明显低于对照组(P < 0.05);移植组大鼠血清转化生长因子β1水平明显高于模型组和对照组(P < 0.05);⑥结果表明,骨髓间充质干细胞移植主要通过调节骨关节炎大鼠体内细胞因子水平和免疫功能发挥治疗作用。

Abstract:

BACKGROUND: As the ability of self-renewal, differentiation and migration into damaged tissues, bone marrow mesenchymal stem cells have been widely used in a variety of diseases.
OBJECTIVE: To explore the therapeutic effect of bone marrow mesenchymal stem cell transplantation on osteoarthritis in rats.
METHODS: Thirty-six Wistar rats were randomly assigned into transplantation, model or control group. osteoarthritis models were established in the transplantation and model groups, followed by tail vein injection of bone marrow mesenchymal stem cells (5×107/kg) or the same volume of normal saline, respectively. Rats in the control group were subjected to no treatment. Four weeks after injection, levels of CD4+CD25+ regulatory T cells in the spleen, interleukin-17, tumor necrosis factor-α and transforming growth factor-β1 in serum were detected, and arthritis index and the degree of joint swelling were evaluated as well.
RESULTS AND CONCLUSION: Compared with the control group, both arthritis index and degree of joint swelling were increased significantly in the model group (P < 0.05), but these indicators exhibited a remarkable improvement after cell transplantation (P < 0.05). Levels of CD4+CD25+ regulatory T cells in the spleen in the three groups were ranked as follows: the transplantation group > the control group > the model group. The levels of interleukin-17 and tumor necrosis factor-α in serum in the transplantation group were lower than those in the model group but higher than those in the control group (P < 0.05). Highest level of transforming growth factor-β1 was obtained in the transplantation group, followed by the control group and model group (P < 0.05). To conclude, these findings indicate that bone marrow mesenchymal stem cell transplantation exert therapeutic effects in osteoarthritis rats by immune and cytokine regulation.
