概括
怀孕早期的尿液细胞外囊 (UEV) 可以通过检测改变的免疫编程来预测早产 (PB). 在UEV中测量特定的免疫媒介为早期PB风险评估提供了一种非侵入性方法.
科学领域:
- 免疫学 免疫学 免疫学
- 产科和妇科 产科和妇科
- 生物标志物 生物标志物
背景情况:
- 免疫编程,特别是巨细胞 (M1/M2) 差异化,会影响怀孕结果,如终产 (TB) 和早产 (PB).
- 孕妇血液中的细胞外囊泡 (EVs) 与怀孕有关,但尿路EVs (UEVs) 作为PB预测的非侵入性生物标志物的作用尚未被探索.
- 了解怀孕早期UEVs中的免疫媒介特征对于识别潜在的PB预测因子至关重要.
研究的目的:
- 调查第一季度携带M1免疫信使的UEV是否可以预测随后的早产 (PB).
- 分析UEV免疫特征与PB与期产 (TB) 的发展之间的相关性.
- 评估UEVs对巨细胞和淋巴细胞分化的影响,包括"训练免疫"标记物.
主要方法:
- 从501名孕妇的队列中分离的第一季度UEV (40个PB,40个匹配的TB).
- 在UEV中量化免疫媒介 (MCP-1,IL-6,IL-17A,IP-10,TNFα,IL-12,IFNγ) 在UEV中.
- 评估UEV对巨/淋巴细胞分化,mRNA表达和H3K4me3染色体修饰的影响.
主要成果:
- 与非怀孕样本相比,第一季度的UEV显示出异构体标志物增加.
- 与结核病相比,经历过PB的女性的UEV具有显著更高的MCP-1,IL-6,IL-17A,IP-10,TNFα,IL-12和IFNγ水平.
- 在UEV中MCP-1和IFNγ水平显示出PB的预测潜力,组合标志物显示出更高的灵敏度.
- 来自PB的UEV促进了M1/Th17分化和H3K4me3修饰,与抑制这些通路的TB衍生的UEV不同.
结论:
- 第一个三个月的UEV含有免疫特征,可以预测早产 (PB).
- 在UEV中检测到的改变的M1和Th17免疫反应是PB风险的早期指标.
- UEV可以作为早期发现PB的非侵入性生物标志物和通过免疫调节预防的潜在治疗点.

Development of Immunocompetence
307
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Overview of Exosomes
2.7K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...
