概括

侵袭性胎盘包括一个"合作"的动态,其中胎儿细胞转化母体组织. 通过改变信号通路, 使这种入侵成为可能, 凸显出共同的进化利益.

科学领域:

生殖生物学和进化发展生物学.
植入的细胞和分子机制.
哺乳动物的繁殖策略.

背景情况:

母胎界面 (MFI) 涉及母亲和胎儿之间的复杂相互作用.
尽管有着共同的遗传利益,但MFI多样性往往被视为母胎冲突.
在血胎位中,子宫内膜纤维细胞 (ESF) 决定调节胚胎植入.

研究的目的:

调查外细胞 (EVT) 与母乳体纤维细胞的相互作用.
阐明EVT促进胎盘入侵的分子机制.
探索母体适应在侵袭性胎盘的演变中的作用.

主要方法:

使用来自热囊细胞干细胞和HTR8/SVneo细胞的分化EVT.
分析了ESF行为和矩阵重建属性的变化.
研究了对体信号传递,特别是IL-11和下游信号传递通路 (JAK/STAT,AP-1).

主要成果:

通过像IL-11这样的膜信号,EVT诱导状ESF从矩阵生产转移到矩阵降解.
非侵入性细胞细胞不会诱导这种转化.
孕产妇的同适应至关重要,ESF对细胞因子信号3抑制剂进行上调,改变IL-11信号从JAK/STAT到AP-1.

结论:

高侵袭性胎盘是通过侵袭性EVT和母体适应的相互作用而演变的.
母体适应包括信号通路的切换 (JAK/STAT到AP-1),以响应胎儿的信号.
这种母亲与胎儿的互动是进化"竞争"的一个例子.

Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Transcytosis of IgG

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
