Using nervous-system signals to help the pregnant immune system

Neuromodulation of maternal immune adaptations in pregnancy

NIH-funded research University of California, San Diego · NIH-11175472

What this research studies

You would hear from researchers at UC San Diego who are studying how the brain and sympathetic nervous system influence immune cells during pregnancy. They will collect blood from people with term and preterm pregnancies and use high-dimensional mass cytometry and blood measurements to see how immune cells respond to adrenergic (stress-related) signals. In parallel, they will use mouse models and targeted neuromodulation of specific brain circuits to test whether increased sympathetic tone drives pro-inflammatory monocytes. The combined human-sample and animal work aims to link nervous-system activity with immune changes that may contribute to preterm birth.

Who could benefit from this research

Good fit: Ideal candidates are pregnant people—especially those in late pregnancy or with risk factors for preterm birth—who can provide blood samples and attend clinic visits at the study site.

Not a fit: People who are not pregnant, already postpartum, or who cannot provide blood samples or attend the study site are unlikely to benefit directly from participating.

Why it matters

Potential benefit: If successful, this work could point to new ways to identify people at higher risk for preterm birth and to therapies that target nerve-immune signals to protect pregnancies.

How similar studies have performed: Studies outside pregnancy have shown the nervous system can change immune responses, but applying neuromodulation to alter pregnancy immune tolerance and prevent preterm birth is largely new.
