Human CD56+CD39+ dNK cells support fetal survival through controlling trophoblastic cell fate:immune mechanisms of recurrent early pregnancy loss

Decidual natural killer（dNK） cells are the most abundant immune cells at the maternal-fetal interface during early pregnancy in both mice and humans, and emerging single-cell transcriptomic studies have uncovered various human dNK subsets that are disrupted in patients experiencing recurrent early pregnancy loss（RPL） at early gestational stage, suggesting a connection between abnormal proportions or characteristics of dNK subsets and RPL pathogenesis. However, the functional mechanisms underlying this association remain unclear. Here, we established a mouse model by adoptively transferring human dNK cells into pregnant NOG（NOD/shi-scid/IL-2Rγnull） mice, where human dNK cells predominantly homed into the uteri of recipients. Using this model, we observed a strong correlation between the properties of human dNK cells and pregnancy outcome. The transfer of dNK cells from RPL patients（dNK-RPL）remarkably worsened early pregnancy loss and impaired placental trophoblast cell differentiation in the recipients. These adverse effects were effectively reversed by transferring CD56+CD39+dNK *** studies revealed that CD56+CD39+dNK subset facilitates early differentiation of mouse trophoblast stem cells（m TSCs） towards both invasive and syncytial pathways through secreting macrophage colony-stimulating factor（M-CSF）. Administration of recombinant M-CSF to NOG mice transferred with dNK-RPL efficiently rescued the exacerbated pregnancy outcomes and fetal/placental development. Collectively, this study established a novel humanized mouse model featuring functional human dNK cells homing into the uteri of recipients and uncovered the pivotal role of M-CSF in fetal-supporting function of CD56+CD39+dNK cells during early pregnancy, highlighting that M-CSF may be a previously unappreciated therapeutic target for intervening RPL.

抑制“两高”企业过度投资,提高企业投资效率是推动经济绿色低碳转型的关键。2007~2021年,“绿色”窗口指导通过限制信贷投放以及强化融资约束遏制了“两高”企业的粗放扩张,减少了企业的非效率投资;“绿色”窗口指导显著提升了国有企业的投资效率,对劳动密集型“两高”企业的影响大于资本密集型企业。“绿色”窗口指导有效减少了污染物排放总量,并对经济增长总量和经济发展质量产生倒U型影响。以“绿色”窗口指导为代表的非市场化货币政策工具能够在优化绿色金融资源配置中发挥关键作用,但长期而言,政府还应积极主动构建市场、完善市场机制,持续推动经济高质量增长。
