自然杀伤(NK)细胞填充蜕膜是重要的调节正常胎盘。与外周血NK细胞(pNK)相比,蜕膜NK细胞(dNK)缺乏细胞毒性,分泌促血管生成因子并调节滋养细胞侵袭。在这里,我们表明暴露于缺氧,转化生长因子β 1和去甲基化剂的组合,导致NK细胞表达杀手细胞免疫球蛋白样受体,dNK细胞标记CD9和CD49a,以及dNK趋化因子受体模式。这些细胞分泌血管内皮生长因子,一种有效的促血管生成分子,显示降低细胞毒性并促进人类滋养细胞系的侵袭。这些发现对与NK细胞生物学改变相关的胎盘疾病具有潜在的治疗应用价值。
Natural killer (NK) cells that populate the decidua are important regulators of normal placentation. In contrast to peripheral blood NK (pNK) cells, decidual NK cells (dNK) lack cytotoxicity, secrete pro-angiogenic factors and regulate trophoblast invasion. Here we show that exposure to a combination of hypoxia, transforming growth factor beta 1, and a demethylating agent, results in NK cells that express Killer cell Immunoglobulin like Receptors, the dNK cell markers CD9 and CD49a, and dNK pattern of chemokine receptors. These cells secrete vascular endothelial growth factor, a potent pro-angiogenic molecule, display reduced cytotoxicity and promote invasion of human trophoblast cell lines. These findings have potential therapeutic applications for placental disorders associated with altered NK cell biology.
