摘要
目的研究NOD/SCID孕鼠胚胎吸收率(Resorption rate,RR)与母-胎界面局部免疫状况的关系。方法计算并比较孕13.5天同基因妊娠NOD/SCID×NOD/SCID小鼠和非免疫缺陷的BALB/c×BALB/c小鼠的RR,并采用4色流式细胞术检测NOD/SCID小鼠非孕期和孕13.5天脾脏和胎盘细胞内细胞因子的表达状况,以明确其与妊娠耐受相关的淋巴细胞功能亚群。结果NOD/SCID小鼠的RR与对照组BALB/c小鼠相比无显著差异。与此相应,虽然能够证实NOD/SCID小鼠具有多重免疫缺陷,但是孕期母-胎界面多种功能性细胞亚群的百分率发生自发性改变。结论NOD/SCID小鼠脾脏和胎盘某些细胞百分率的自发性改变可能对妊娠结局有利。
Objective:To evaluate the relationship between the embryo resorption rate (RR) and the status of local immunity at the feto-maternal interface in pregnant NOD/SCID mice. Methods: RR was calculated in syngeneically impregnated NOD/SCID × NOD/SCID mice and compared with non-immunodeficiency BALB/c × BALB/c mice at day 13. 5 of gestation. Intracellular expression of cytokines was performed with four-color flow cytometry to identify the functional subsets of splenocytes and placental cells in NOD/ SCID mice before bred or during pregnancy. Results:No statistically supported difference in RRs was observed between NOD/SCID and control BALB/c mice. Accordingly, although multiple immunodeficits were confirmed in NOD/SCID mice, the percentages of several functional cell subsets were spontaneously altered during pregnancy, and this may be correlated with the roughly normal pregnancy outcomes observed in these mice. Conclusion:The spontaneous alteration of cell percentages at the feto-maternal interface in NOD/SCID mice may be beneficial to the pregnancy outcomes.
