概括
2,3,7,8-四二二氧化 (TCDD) 暴露会破坏母胎免疫平衡,可能导致口腔裂 (CP). 用弗莱恩德的完整辅助剂 (FCA) 治疗部分逆转了这些效应,这表明MFI免疫平衡是关键.
科学领域:
- 生殖免疫学 生殖免疫学
- 发展性毒理学 发展性毒理学
- 环境健康 环境健康
背景情况:
- 2,3,7,8-四二二氧化 (TCDD) 是一种已知的破坏免疫平衡的环境污染物.
- TCDD被认为是 palatal cleft (CP) 形成的一个因素.
- 母胎界面 (MFI) 在怀孕和免疫调节中起着至关重要的作用.
研究的目的:
- 调查TCDD是否通过破坏母胎界面 (MFI) 的免疫平衡来诱导口腔裂 (CP).
- 探索弗洛恩德的完整辅助剂 (FCA) 对TCDD诱导的MFI免疫力和CP的潜在保护作用.
主要方法:
- C57BL/6J小鼠被暴露在TCDD中,有或没有FCA治疗.
- 分析包括组织学检查 (H&E),免疫细胞的流细胞计 (Th1,Th2) 和细胞因子水平的ELISA (IFN-γ,IL-4).
- 测量侧重于胎盘发育和 palatal 架附近.
主要成果:
- 暴露于TCDD显著减少了胎盘大小,血管化和MFI细胞面积,以及母体血液中的Th1/Th2细胞和关键细胞因子 (IFN-γ,IL-4) 的减少.
- FCA治疗部分恢复了胎盘参数,并增加了Th1/Th2细胞计数,特别是Th2细胞,表明免疫调节作用.
- FCA治疗也减少了口腔架之间的距离,表明潜在的缓解CP的发展.
结论:
- 通过破坏母胎界面 (MFI) 免疫恒温,TCDD可能会诱导口腔裂 (CP).
- FCA治疗表明,它有可能抵消TCDD对MFI免疫力和胚胎发育的不良影响.
- 需要进一步的研究来阐明TCDD对MFI免疫调节的影响的确切机制.

Development of Immunocompetence

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.

Teratogenicity
2.3K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
