Why the placenta becomes vulnerable to CMV (cytomegalovirus)

Trophoblast development and placental susceptibility to cytomegalovirus infection

NIH-funded research University of Minnesota · NIH-11322105

Researchers will look at placenta cells to understand when and how CMV can infect the placenta during pregnancy and how to better protect babies before birth.

What this research studies

The team will use lab-grown human placental (trophoblast) stem cells and follow them as they differentiate to see when cells lose their natural antiviral defenses. They will compare gene activity between early, resistant cells and later, more vulnerable cells, and use CRISPR-based gene editing to turn specific genes on or off to find which ones protect against CMV. Promising protective factors will be tested in relevant models of the placenta to confirm their role. The goal is to identify pathways or molecules that could one day be targeted to prevent placental infection and congenital CMV.

Who could benefit from this research

Good fit: People most relevant to this work would include pregnant individuals—especially early in pregnancy—or those willing to donate placental tissue or clinical samples, and those with recent or suspected CMV infection.

Not a fit: People seeking immediate treatment for CMV or non-pregnant individuals are unlikely to get direct or immediate personal benefit from this laboratory-focused research.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent CMV from crossing the placenta and reduce the risk of congenital CMV in newborns.

How similar studies have performed: Previous lab studies show some placental cells resist CMV through interferon-stimulated genes, but using unbiased CRISPR screens to pinpoint protective factors is a newer and less-tested approach.
