Abstract:
Objective:To probe into effects of Mifepristone on the Th1/Th2 balance at materno-fetal interface.Methods:Sixty three healthy women in early pregnancy were randomized into two groups,30 women used mifepristone 200 mg,and 33 women as control.Their decidual tissue was collected by curettage in 48 hours of taking the drug.The Th1/Th2 cytokine expressions in decidua were analyzed by immunohistochemistry.Results:In the decidual tissue of normal early pregnancy,there were significantly higher densities of Th2 cytokines,IL-4 and TGF-?2,and lower density of Th1-type cytokine,IFN-? and IL-2.After having treated by Mifepristone,the decidual tissue appeared to significantly higher densities of Th1-type cytokines(IL-2, IFN-?).Conclusion:Our findings suggest that Mifepristone can up-regulate expression of the Th1-type cytokines,and cause a shift towards Th1 bias,which leads to abortion.
