PG - 247-255 LID - 10.1530/REP-19-0172 [doi] AB - During pregnancy, the maternal immune system must tolerate the persistence of semi-allogeneic fetus in the maternal tissue. Inadequate recognition of fetal antigens may lead to pregnancy complications, such as recurrent miscarriage (RM) and recurrent implantation failure (RIF). Dendritic cells (DCs) are key regulators of protective immune responses and the development and maintenance of tolerance. Regarding that DCs are important in the establishment of immune tolerance in human pregnancy, it would be important to study the microenvironment in which DCs reside or are activated may affect their functions toward tolerance rather than active immune response. IL-10 plays a critical role in the maintenance of normal pregnancy, and the increased production of IL-10 is associated with successful pregnancy. In this study, we provide an in-depth comparison of the phenotype and cytokine production by DC-10 and other DC subsets, such as iDC and mDC. CD14+ monocyte-derived DCs were differentiated in the presence of IL-10 (DC-10) in vitro from ten normal fertile controls, six RM women and seven RIF women, and characterized for relevant markers. DC-10 was characterized by relatively low expression of costimulatory molecule CD86, as well as MHC class II molecule HLA-DR, high expression of tolerance molecules HLA-G, ILT2, ILT4 and immunosuppressive cytokine IL-10, but produced little or no proinflammatory cytokines, such as TNF-alpha, IL-6 and IL-12p70. Our study provides a better understanding of the phenotypical properties of DC-10, which may participate in the complex orchestration that leads to maternal immune tolerance and homeostatic environment in human pregnancy.
