Treating preeclampsia by targeting protein buildup and faulty cell cleanup (autophagy)
Targeting proteinopathy/tauopathy and impaired autophagy for mechanistic understanding and therapeutic intervention of preeclampsia
This project looks at whether trehalose-like sugars can restore cells' cleanup systems and reduce toxic protein clumps that contribute to preeclampsia in pregnant people.

What this research studies
Researchers found that preeclampsia and Alzheimer’s share problems with toxic protein clumps and impaired cellular cleanup (autophagy). They will study placenta tissue and trophoblast cells and use humanized mouse models to see how protein aggregates form, trigger inflammation, and affect blood-vessel support for the fetus. The team will test trehalose and a related compound, lactotrehalose, to see if these sugars restore autophagy, reduce protein aggregation, and improve cell function. Lab studies on human cells, animal models, and analysis of human placenta samples will be combined to guide future patient-focused treatments.
Who could benefit from this research
Good fit: Ideal candidates for future related trials or for providing samples would be pregnant people diagnosed with or at high risk for preeclampsia who can attend the study site or affiliated clinics.
Not a fit: People who are not pregnant or whose pregnancy hypertension has causes unrelated to protein aggregation or impaired autophagy are unlikely to benefit from this project.
Why it matters
Potential benefit: If successful, this work could lead to new treatments that clear harmful protein clumps, reduce inflammation, and lower the risk or severity of preeclampsia for pregnant people and their babies.
How similar studies have performed: Early laboratory and animal studies with trehalose-like compounds have shown promise in restoring autophagy and reducing protein aggregates, but these approaches are not yet proven in pregnant people.
