概括
COVID-19 感染加剧了胎盘变化,导致更严重的肌和血管变化. 然而,许多观察到的变化反映了孕前的严重程度,而不是直接的病毒影响.
科学领域:
- 产科和妇科 产科和妇科
- 病理学 病理学 病理学
- 传染性疾病 传染性疾病
背景情况:
- SARS-CoV-2 感染对胎盘病理在孕前的影响尚未完全理解.
- 评估胎盘形态在怀孕中复杂的COVID-19和子宫前是至关重要的.
研究的目的:
- 在怀孕期间评估COVID-19妇女的形态胎盘变化.
- 为了区分与COVID-19相关的变化和与孕前相关的变化.
主要方法:
- 来自四组胎盘的组织学和免疫组织化学分析:COVID-19有孕前,COVID-19没有孕前,没有COVID-19的孕前和正常怀孕.
- 使用的特定抗体:SARS-CoV-2尖端蛋白,DPP4 (CD26) 和VEGF.
- 在不同组的胎盘变化和蛋白质表达的比较.
主要成果:
- 来自COVID-19和孕前联合感染的胎盘显示出最严重的筋膜和血管损伤.
- 怀孕前症组表现出增加的胆管病变,纤维素沉积和状成熟,无论COVID-19状态如何.
- 在胎盘组织中检测到SARS-CoV-2尖端蛋白和CD26;VEGF水平与大流行前相似.
结论:
- COVID-19加剧了胎盘的血管变化,但严重的孕前是这些变化的主要原因之一.
- 炎症性胎盘变化不是特定于COVID-19的.
- 在胎盘结构中可以检测到SARS-CoV-2尖端蛋白和CD26,而VEGF水平保持稳定.

01:14Fetal Circulation
2.4K
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...

01:07Teratogenicity
3.9K
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...

01:15Transcytosis of IgG
4.0K
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...

01:24Gonadal and Placental Hormones
2.7K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
