Endometrial immune profiling: Bridging pre-eclampsia research with infertility solutions

Area of Science:

• Reproductive immunology and obstetrics

Background:

• Assisted reproductive technologies (ART) have improved but still have suboptimal success rates.
• Endometrial immune profiling assesses the uterine immune environment for implantation and pregnancy outcomes.
• Spiral artery remodeling is crucial for normal placentation; poor remodeling is linked to obstetrical complications.

Purpose of the Study:

• To review the link between endometrial biomarkers during the implantation window and key factors in human placentation.
• To discuss the potential of endometrial immune profiling for predicting obstetrical risk and preventing pregnancy pathology.

Main Methods:

• Review of published evidence on endometrial immune biomarkers and their relation to placentation.
• Analysis of the association between spiral artery remodeling and pregnancy complications.

Main Results:

• Endometrial biomarkers correlate with immune factors critical for human placentation.
• Poor uteroplacental spiral artery remodeling is associated with preeclampsia, fetal growth restriction, and other major obstetrical syndromes.

Conclusions:

• Endometrial immune profiling prior to conception is a promising indicator for predicting high obstetrical risk.
• Further understanding of underlying mechanisms could lead to prevention strategies for pregnancy-related pathologies.
