Early pregnancy events, including embryo implantation, are critical for maintaining a healthy pregnancy and facilitating childbirth. Despite numerous signaling pathways implicated in establishing early pregnancy, a comprehensive understanding of implantation remains elusive.
This paper provides a comprehensive review of the current research on lipids in the context of early pregnancy, with a particular focus on feto-maternal communications.
Embryo implantation entails direct interaction between uterine tissues and embryos. Introducing embryos triggers significant changes in uterine epithelial morphology and stromal differentiation, facilitating embryo implantation through communication with uterine tissue. Studies employing genetic models and chemical compounds targeting enzymes and receptors have elucidated the crucial roles of lipid mediators-prostaglandins, lysophosphatidic acid, sphingosine-1-phosphate, and cannabinoids-in early pregnancy events.
Given the high conservation of lipid synthases and receptors across species, lipid mediators likely play pivotal roles in rodents and humans. Further investigations into lipids hold promise for developing novel diagnostic and therapeutic approaches for infertility in humans.
早期妊娠事件,包括胚胎着床,对于维持健康妊娠和促进分娩至关重要。尽管有许多信号通路参与早期妊娠的建立,但对着床的全面理解仍然难以捉摸。
本文全面综述了早期妊娠背景下当前关于脂质的研究,特别关注母胎通讯。
胚胎着床需要子宫组织与胚胎之间的直接相互作用。引入胚胎会引发子宫上皮形态和基质分化的显著变化,通过与子宫组织的通讯促进胚胎着床。采用针对酶和受体的遗传模型和化合物的研究已经阐明了脂质介质——前列腺素、溶血磷脂酸、鞘氨醇-1-磷酸和大麻素——在早期妊娠事件中的关键作用。
鉴于脂质合成酶和受体在物种间具有高度保守性,脂质介质可能在啮齿动物和人类中发挥关键作用。对脂质的进一步研究有望为开发人类不孕症的新型诊断和治疗方法带来希望。
