NK细胞是妊娠期间母胎界面中最丰富的淋巴细胞群。子宫NK细胞(uNK)是瞬时的,具有独特的免疫表型并产生许多细胞因子。这些细胞因子在建立和维持与成功妊娠相关的血管重塑和耐受中起重要作用。uNK细胞在妊娠期间也表达TIM-3,并且TIM-3表达的阻断导致小鼠的胎儿丢失。在这项研究中,我们确定了TIM-3阻断对uNK细胞的影响。具体而言,我们观察了TIM-3阻断后uNK细胞的表面受体表型和细胞因子产生。我们的研究结果表明,TIM-3在调节uNK细胞中起作用,并有助于维持胎儿-母体界面的耐受性。
NK cells are the most abundant lymphocyte population in the feto-maternal interface during gestation. The uterine NK cells (uNK) are transient, have a unique immunophenotype and produce a number of cytokines. These cytokines play an important role in establishment and maintenance of vascular remodeling and tolerance associated with successful pregnancy. The uNK cells also express TIM-3 during gestation and blockade of TIM-3 expression results in fetal loss in mice. In this study we determined the effect of TIM-3 blockade on uNK cells. Specifically we observed surface receptor phenotype and cytokine production by uNK cells following TIM-3 blockade. Our results show that TIM-3 plays a role in regulating the uNK cells and contributes to the maintenance of tolerance at the feto-maternal interface.
