概括
肥胖和像棕酸盐这样的和脂肪酸会在怀孕期间恶化B组链球菌 (GBS) 感染. 羊膜层可能会防止炎症,而油酸盐可以减少炎症,从而提供有关代谢综合征风险的见解.
科学领域:
- 生殖免疫学 生殖免疫学
- 代谢障碍 代谢障碍 代谢障碍
- 微生物的病原发生.
背景情况:
- 胆 ?? 膜炎 (CAM),通常是由B组链球菌 (GBS) 引起的,是一种主要的妊娠并发症.
- 肥胖与增加GBS殖民和妊娠并发症有关.
- 孕期膜有不同的层:果性树皮细胞 (DSC),细胞质细胞 (CTB),介质细胞和乳腺上皮细胞 (AEC),其中巨细胞是关键的免疫细胞.
研究的目的:
- 为了研究棕酸,一种常见的和脂肪酸,对每个妊娠膜层对GBS感染的炎症反应的影响.
- 了解代谢因素,如与肥胖相关的脂肪酸,如何影响与GBS相关的妊娠并发症.
主要方法:
- 利用人类细胞系和来自妊娠膜的初级人体组织.
- 对GBS和palmitate暴露的DSC,CTB,AEC和巨细胞.
- 分析了炎症性蛋白质和细胞因子的产生.
- 共同培养和油酸 (单不和脂肪酸) 的研究影响.
- 检查了整个妊娠膜活检.
主要成果:
- 帕尔米增强了GBS的扩散,并与GBS协同诱导DSC,CTB和巨细胞中的炎症蛋白 (例如IL-1β,MMP9),但不是AEC.
- 巨细胞与DSC或CTB的共同培养在共同刺激下放大了炎症反应.
- 活检中的羊膜层似乎减少了对GBS和palmitate的反应中的炎症.
- 油酸盐减轻了棕酸盐的促炎作用.
结论:
- 不同的妊娠膜层对GBS感染表现出不同的免疫反应,由和脂肪酸调节.
- 帕尔米的炎症抑制作用突显出一种潜在的机制,它将肥胖与与GBS相关的怀孕风险增加联系起来.
- 羊膜层的抗炎作用和油酸盐的缓解作用需要进一步研究.

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.

2.7K
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...
