Objective To investigate the effect of FTY720-treated immature bone marrow-derived dendritic cells(BMDCs) on the embryo resorption rate in the CBA/J× DBA/2 abortion mouse model.Methods The dendritic cells(DCs) were derived from bone marrow of DBA/2 mice, and then co-cultured with FTY720. The abortion mouse models were established by mating female CBA/J mice with DBA/2 mice. Via the CBA/J×DBA/2 abortion mouse model, six groups were established, group A: normal pregnancy model; group B: abortion mouse model with no treatment; group C: abortion mouse model injected with DC culture medium(DCCM); group D: abortion mouse model injected with DC; group E: abortion mouse model injected with FTY720; group F: abortion model mouse injected with FTY720-DC. The differences were compared in the embryo resorption rates of the CBA/J ×DBA/2 abortion mouse model treated with FTY720-DC or different controls observed on gestation day 12 to 14, and then the microenvironment in murine pregnancy was investigated.Results The embryo resorption rate was statistically significantly decreased in group D and group E when they compared with group B and group C(P〈0.05, respectively).Furthermore, the embryo resorption rate in group F showed a statistically significant decrease when compared with the other groups except group A(P〈0.01). These resultssuggest that FTY720-DCs possess a notable advantage over DCs or FTY720 in reducing the embryo resorption rate of the abortion mouse model. The percentage of Th17(IL-17+CD4+T cells) in peripheral blood mononuclear cell(PBMC) in the abortion mouse model was 4.35%±0.34% before treated with FTY720-DC, and was1.34%±0.28% after treated with FTY720-DC(P〈0.01). The percentage of Tregs(CD4~+CD25~+Foxp3~+T cells) in PBMC was significantly increased in group F(8.35%±1.80%) as compared with group B(2.68%±0.65%)(P〈0.01).Conclusion Adoptive transfer of FTY720-DC can statistically significantly reduce the embryo resorption rate in the CBA/J×DBA/2 abortion mouse model. The lower embryo resorption rate in the FTY720-DC treated abortion mouse model may be caused by the imbalance of Treg/Th17. 展开更多
