NK cell-derived IL-10 is critical for DC-NK cell dialogue at the maternal-fetal interface
Abstract DC-NK cell interactions are thought to influence the development of maternal tolerance and de novo angiogenesis during early gestation. However, it is unclear which mechanism ensures the cooperative dialogue between DC and NK cells at the feto-maternal interface. In this article, we show th...
