摘 要: | 目的:探讨胸腺基质淋巴细胞生成素(TSLP)与原因不明复发性流产(URSA)的关系。方法:建立研究组自然流产小鼠模型(CBA/J×DBA/2)和对照组正常妊娠小鼠模型(CBA/J×Balb/c),采用免疫印迹(Western Blot)方法和实时荧光定量聚合酶链式反应(RT-PCR)方法检测绒毛、蜕膜组织中TSLP的表达;采用酶联免疫吸附双抗体夹心(ELISA)方法检测外周血TSLP、细胞因子白介素-4(IL-4)及干扰素-γ(IFN-γ)的表达;采用流式细胞仪检测调节性T细胞(Treg)表面FoxP3的表达。结果:RT-PCR法检测自然流产模型组绒毛组织中TSLP的表达低于正常妊娠模型组(P<0.05);Western Blot法分析显示自然流产模型组绒毛、蜕膜组织中TSLP的表达低于正常妊娠模型组(P<0.05);ELISA法检测自然流产模型组血清中TSLP、IL-4的表达低于正常妊娠模型组(P<0.05),而IFN-γ的表达较正常妊娠模型组未见明显增高(P>0.05);流式细胞仪检测自然流产模型组CD4+CD25+Treg和FoxP3的表达明显低于正常妊娠模型组(P<0.05)。结论:TSLP明显降低,可能是导致URSA患者母胎界面免疫耐受异常的重要原因。

Abstract: | Objective:To investigate the relationship between thymic stromal lymphopoietin(TSLP)and unexplained recurrent spontaneous abortion(URSA)。Methods:The mouse models of spontaneous abortion (CBA/J×DBA/2)and normal pregnancy(CBA/J×Balb/c)were established.The expression of TSLP in chorion and decidual tissues was screened by RT-PCR、Western Blot.ELISA was applied to detect expression of cytokines TSLP、cytokines IL-4 and IFN-γfrom peripheral blood.The expression of FoxP3 was detected by FACs.Results:Real-time PCR analysis indicated that the expression of TSLP in chorion spontaneous abortion model group was lower than normal pregnancy model group(P<0.05).Western Blot analysis indicated that the expression of TSLP in chorion and decidua spontaneous abortion model group was lower than normal pregnancy model group(P<0.05).The expression of TSLP and IL-4 in spontaneous abortion model group was lower than in normal pregnancy model group(P<0.05),but the expression of IFN-γwas no significant change than in normal pregnancy model group(P>0.05);The expression of CD4 + CD25 + Treg and FoxP3 in spontaneous abortion model group was significant lower than in normal pregnancy model group (P<0.05).Conclusions:The obvious decrease of TSLP might be an important factor for the disturbance of fatal-maternal immune-tolerance. |
