Immunomodulatory effects of Salvianolic acid B in a spontaneous abortion mouse model.

Abstract

Pregnancy is a kind of natural immune tolerance. Immune factors play an important role in recurrent spontaneous abortion and repeated implantation failure. Salvianolic acid B (SalB) has anti-tumor, anti-inflammatory, anti-oxidation and immunomodulatory functions. However, there are few reports on the relationship between SalB and maternal-fetal immune tolerance. In this study, CBA/J × DBA/2 J mice as a spontaneous abortion mouse model were given SalB. The results showed that the abortion rate was significantly decreased after SalB treatment. The populations of Nkp46 and cytotoxic CD8+ T cells in the placenta of female mice treated with SalB were significantly decreased. The qRT-PCR showed that SalB was able to significantly reduce the expression of pro-inflammatory factors and Toll-like Receptor in the placenta. In addition, SalB was able to increase the area of the labyrinth in the placenta. In conclusion, these findings suggest that SalB is beneficial for the immune-modulation at the maternal-fetal interface in a spontaneous abortion mouse model, resulting in a decrease in the abortion rate. This may encourage new ideas for the treatment of patients with repeated implantation failure.
