Pregnant women with systemic lupus erythematosus (SLE) have an increased risk of maternal complications and adverse fetal outcomes. To better predict and prevent adverse outcomes of SLE pregnancies, it is crucial to understand the underlying biological processes.
Failing maternal-fetal tolerance is thought to play an important role in the increased risk for pregnancy complications in SLE patients. However, it is unknown which mechanisms mediate maternal-fetal tolerance and how the dysregulated immune system in SLE affects this process.
This study will identify potential therapeutic targets based on the mechanisms underlying failing maternal-fetal tolerance in SLE. Furthermore, it will deliver potential biomarkers for early detection of developing complications. Thereby, the findings in this study will contribute to the improvement of SLE pregnancy outcomes with benefits for both mother and child.
The overall objective of this research is to delineate which cellular processes mediate failing maternal-fetal tolerance in SLE patients. Furthermore, the aim is to define potential biomarkers for earlier detection of complications. The group hypothesises that the abnormally regulated immune system in SLE patients causes aberrant interactions at the maternal-fetal interface, resulting in failure of immunological tolerance.
This study greatly advances our understanding of the processes leading to pregnancy complications in SLE patients. This is a crucial first step in better predicting and improving
pregnancy outcomes for SLE patients, for example by monitoring the cells identified in the final part of our project in the blood of women with SLE. This work will also be a benefit for future research to develop intervention strategies to reduce pregnancy complications.
