Can targeting regulatory T cells help with pregnancy complications like spontaneous abortion?
Regulatory T cells (Tregs) are a type of immune cell that play a critical role in maintaining the balance between the mother's immune system and the developing fetus. When these cells are not functioning correctly, it can increase the risk of pregnancy complications like recurrent spontaneous abortion (RSA).
What the research says
Research shows that an imbalance in T cells—specifically a lack of proper regulation between T helper 17 cells and regulatory T cells—can lead to a failure of immune tolerance between the mother and the fetus 1. This imbalance is linked to cases of recurrent spontaneous abortion where other causes are unknown 1.
Scientists are currently exploring various ways to target these cells to improve pregnancy outcomes. Potential strategies include hormonal support, intravenous immunoglobulin, and newer methods like immunometabolic reprogramming or engineered cellular therapies 25. However, while these treatments have been used in areas like organ transplants and autoimmune diseases, their use specifically for pregnancy complications is still in its infancy and currently lacks reported results regarding safety or effectiveness 25.
What to ask your doctor
- What role do regulatory T cells (Tregs) play in preventing spontaneous abortion?
- Are there any current clinical trials or emerging therapies involving Treg cell modulation for pregnancy complications?
- How does my specific health profile influence the risk of recurrent spontaneous abortion?
- Are there other factors, such as gut health or specific biomarkers, that can be addressed to improve pregnancy outcomes?
