A new study offers hope for women facing the potentially deadly pregnancy complication,pre-eclampsia.
Pre-eclampsia, characterized by high blood pressure and restricted blood flow to the fetus, affects 3 to 5% of pregnancies and is a leading cause of stillbirths and premature births worldwide. Currently, there is no known cure for pre-eclampsia, and treatment options only address symptoms, leaving many women facing tough choices that impact both their health and the health of their babies.
Kelsey Swingle, a doctoral student in the bioengineering lab at the University of Pennsylvania, is resolute to change that.Her groundbreaking research, published in Nature [[1](https://www.nature.com/articles/s41586-024-08291-2)],focuses on harnessing the power of mRNA therapy to effectively treat pre-eclampsia.
Swingle’s research involved testing 98 different lipid nanoparticles (LNPs)—tiny delivery vehicles designed to carry therapeutic mRNA into cells. Her goal was to identify an LNP that could effectively deliver mRNA to the placenta in pregnant mice wiht induced pre-eclampsia. Remarkably, she found an LNP that achieved over 100 times greater mRNA delivery than a currently FDA-approved LNP formulation.
The results were undeniably promising. “Our LNP was able to deliver an mRNA therapeutic that reduced maternal blood pressure through the end of gestation and improved fetal health and blood circulation in the placenta,” explains Swingle.“Additionally, at birth we saw an increase in litter weight of the pups, which indicates a healthy mom and healthy babies. I am very excited about this work and it’s current stage because it could offer a real treatment for pre-eclampsia in human patients in the very near future.”
Paving the Way for Future Research
Swingle’s achievement is a significant step forward, not only for pre-eclampsia but also for the broader field of reproductive health. Her pioneering work in establishing a mouse model of pre-eclampsia opens new doors for researching LNP-mRNA therapeutics for other reproductive health challenges. As Swingle notes, “It turns out that there are relatively few studies that have been done with mRNA lnps in pregnant mice, and little to none done in pre-eclamptic mice.” Her dedication to developing and refining this model lays the foundation for future research that could benefit countless women.
While further progress and clinical trials are necessary before this therapy becomes widely available to humans, Swingle’s groundbreaking research offers a beacon of hope for women facing pre-eclampsia and their families. It represents a significant step towards a future where this potentially deadly complication is treatable, leading to healthier pregnancies and outcomes for mothers and babies alike.
Potential Breakthrough in Pre-eclampsia Treatment
Researchers at the University of Pennsylvania have made significant strides in developing a potential treatment for pre-eclampsia, a serious pregnancy complication characterized by high blood pressure and organ damage. the team, led by Ph.D.candidate Emily Swingle, has successfully used lipid nanoparticles (LNPs) to deliver mRNA that targets and cures pre-eclampsia in mice. In their study, Swingle and her colleagues induced pre-eclampsia in pregnant mice and administered a single dose of the LNP-mRNA therapy on day 11 of gestation. This single injection effectively cured the condition in the mice until the end of their pregnancy, a promising result that warrants further investigation. “At this stage in our research, we would bring this LNP to larger animals such as rats and guinea pigs first to determine how well it works in the ‘gold standard’ models of pre-eclampsia before we could advance this work to human trials,” explained Swingle. the team is notably interested in studying the effects of the LNP-mRNA therapy in guinea pigs. “Testing our LNP on guinea pigs will be particularly interesting, as their placenta closely resembles a human’s and their gestational period is longer, up to 72 days. We will be asking the questions ‘How many doses do these animals need?’ ‘Will the minimum effective dose change?’ and ‘How well does our current LNP work in each?’” stated Swingle. The researchers acknowledge that they still need to optimize the LNP for more efficient mRNA delivery and fully understand how it reaches the placenta. Funding from the National Institutes of Health and the national Science Foundation will support these further investigations. The team is keen about the potential of this therapy and is already exploring the possibility of creating a spin-off company to bring it to clinical trials and ultimately to the market. Swingle’s groundbreaking research not only advances the field of pre-eclampsia treatment but also inspires other young scientists in the field of women’s health. First of its Kind Brain Surgery on Baby Inside the Womb has Successfully Prevented Heart Failure## Archyde Interview: Kelsey Swingle on A Potential Cure for Pre-eclampsia
**Interviewer:** Welcome to Archyde, Kelsey Swingle. Your groundbreaking research on pre-eclampsia has generated meaningful excitement in the scientific community. Coudl you tell us in simple terms what pre-eclampsia is and why itS such a serious condition?
**Kelsey Swingle:** Pre-eclampsia is a pregnancy complication characterized by high blood pressure and restricted blood flow to the fetus. It’s a leading cause of premature births and stillbirths globally, affecting 3 to 5% of pregnancies. Currently, there’s no cure, only treatments to manage symptoms. This leaves many expecting mothers facing difficult choices that can impact both their health and the well-being of their babies.
**Interviewer:** Your research focuses on mRNA therapy, a groundbreaking technology. How does your approach work to address pre-eclampsia?
**Kelsey Swingle:** We’re leveraging the power of mRNA to deliver a therapeutic directly to the placenta in pregnant mice. Think of mRNA as a blueprint that instructs cells to produce specific proteins.We designed an mRNA molecule that can effectively reduce blood pressure and improve blood flow to the fetus.
**Interviewer:** You developed a unique lipid nanoparticle (LNP) for this therapy. Why is the LNP so crucial in this process?
**Kelsey Swingle:** LNPs act as tiny delivery vehicles for the mRNA. They protect the genetic material and help it reach the target cells in the placenta. Our research involved testing 98 different LNPs and we identified one that achieved over 100 times greater mRNA delivery compared to a currently FDA-approved LNP.This is a crucial breakthrough!
**Interviewer:** What where the key findings of your study?
**Kelsey Swingle:** Our LNP successfully delivered the mRNA therapeutic to the placenta in pregnant mice with pre-eclampsia. This led to a significant reduction in maternal blood pressure throughout their pregnancy,improved fetal health,and better blood circulation within the placenta. Excitingly, we also observed an increase in the weight of the pups at birth, indicating healthy mothers and babies.
**Interviewer:** Those are truly remarkable results. what are the next steps for your research and what does this mean for potential treatments for pre-eclampsia in humans?
**Kelsey Swingle:** We’re thrilled with these findings. The next steps involve further testing and refining our LNP-mRNA therapy. We’re hopeful that this approach could lead to a real treatment for pre-eclampsia in human patients in the near future.
**Interviewer:** Your work isn’t just significant for pre-eclampsia; it opens pathways for other reproductive health challenges. Can you elaborate on that?
**Kelsey Swingle:** By establishing and refining this mouse model of pre-eclampsia, we’ve created a valuable tool for researchers exploring other reproductive health issues.There are very few studies using mRNA LNPs in pregnant mice, particularly those with pre-eclampsia. This work lays the groundwork for future research that could benefit countless women.
**Interviewer:** Kelsey Swingle, thank you for sharing your groundbreaking research with Archyde. Your work offers a beacon of hope for expecting mothers around the world.
