Flu-triggered immune signals in pregnancy
Control of influenza virus induced type I interferon signaling during pregnancy
This project looks at whether a hormone-linked signaling pathway helps protect unborn babies from harmful immune reactions caused by influenza in pregnant people.

What this research studies
The research team used a genome-wide CRISPR/Cas genetic screen to find a hormone-related pathway (GPER1) that appears to shield fetal tissues from type I interferon signals produced during maternal flu infection. In laboratory models, disrupting this pathway caused fetal problems as severe as direct congenital infections, while having little effect on the mother's illness. The protective activity was specific to reproductive and fetal tissues. The goal is to better understand and eventually control these immune signals during pregnancy to keep fetuses safe from virus-driven damage.
Who could benefit from this research
Good fit: Pregnant people—especially those exposed to or recovering from influenza or willing to donate pregnancy-related samples—would be the most relevant participants if human participation is included.
Not a fit: People who are not pregnant or whose health issues are unrelated to pregnancy or viral respiratory infections are unlikely to receive direct benefit from this work.
Why it matters
Potential benefit: If successful, this work could lead to ways to protect pregnancies from fetal harm caused by maternal influenza and similar viral infections.
How similar studies have performed: Prior studies showed type I interferons can harm fetal development, but identifying and targeting a GPER1-dependent protective pathway is a newer finding still being explored.
