Summary
Preeclampsia is a dreaded disease of pregnancy, globally responsible for thousands of deaths of mothers and babies. It is caused by a protein called sFlt-1 leaking out of the placenta and attacking the mothers organs. Recently, a new sflt-1 subtype was discovered that is specific to the placenta. It may be the key disease causing toxin in preeclampsia. We will target this placental specific sFlt-1 to generate diagnostics to predict preeclampsia, and explore novel ways to block the toxic effects ....Preeclampsia is a dreaded disease of pregnancy, globally responsible for thousands of deaths of mothers and babies.

Nanomedicine Targeted Delivery Of Therapeutics To The Placenta To Treat Preeclampsia

Summary
Preeclampsia, one of the most serious complications of pregnancy, affects around 3-8% of all pregnancies. Sadly, there is no treatment. We have developed a new technique to deliver treatments only to the placenta, sparing the mother and baby from side effects. We will test whether this technique can treat the source of preeclampsia, the placenta, in human and mouse models in our laboratory. This work has potential to offer possibilities of new treatments to other pregnancy complications.
Systematic Screening Approach To Identify New Therapeutics For Preeclampsia

Summary
Preeclampsia is a pregnancy complication where factors are released from the placenta into the mum's bloodstream, causing widespread blood vessel and organ damage. Sadly, there is no treatment. Our laboratory has a set up a system to test whether drugs might be useful as a treatment for preeclampsia. We test whether the drugs decrease the release of these factors and protect blood vessels. In this grant, we propose testing three exciting drug treatments for preeclampsia.
Cell-cell fusion is critical for the development and transport capacity of the placenta during pregnancy. Impairments in this process occur in pregnancy complications such as preeclampsia (PE). We have identified a novel pathway (LY6E) regulating placental cell-cell fusion which is also dysregulated in human pregnancies complicated by PE. In the current proposal we will investigate the mechanisms by which LY6E mediates cell-cell fusion and examine its role in the development of PE.
The Pathogenic Role Of A Placenta-specific Protease In Early-onset Preeclampsia

Summary
Preeclampsia (PE) is a life-threatening disorder of pregnancy. If left untreated, PE will lead to maternal as well as fetal death. Unfortunately, the only current effective “cure” for PE is to deliver the baby prematurely. The causes of PE are intrinsically related to the placenta, the organ that connects the fetus to the mother. This project will investigate a unique enzyme that is produced only by the placenta, its contribution to PE and its potential as a target for PE treatment.
New Generation Antiplatelet Therapies To Prevent Preeclampsia

Summary
Preeclampsia, a major complication of pregnancy, affects around 3-8% of pregnancies. Sadly, there is no way to prevent or delay disease. We have uncovered antiplatelet agents, used to prevent heart disease and stroke, may provide health benefits to women at risk of developing preeclampsia. We will test whether these agents can prevent the pathophysiology of preeclampsia in specialized human & mouse models developed in our laboratory. This work may provide a prevention strategy for preeclampsia.
Can Esomeprazole Improve Outcomes In Women At High Risk Of Pre-eclampsia? A Phase II Placebo-controlled Randomised, Multi-centre Clinical Trial.

Funding Amount
$1,597,125.00
Summary
Pre-eclampsia, recognised through the development of high blood pressure in pregnancy, causes death and/or injury to mothers and babies. An improved understanding of the development of pre-eclampsia has provided opportunities for early prediction and prevention of disease. We will use a powerful predictive model to identify pregnancies at high risk of pre-eclampsia then observe the effect of a novel treatment (esomeprazole) on maternal blood pressure and the development of this disease.
From Pathogenesis To Therapeutics: Targeting Two Signalling Pathways As A Therapeutic Strategy To Treat Preeclampsia

Summary
Preeclampsia is a serious complication of pregnancy that claims the lives of thousands of mothers and babies each year. There is no efficacious medical treatment besides delivery of the baby and placenta. Our lack of therapeutics is largely a result of our poor understanding of the disease. In this application we plan to thoroughly characterise two pathways we believe responsible for preeclampsia, effectively identifying many points at which new therapies could be targeted.
Understanding The Role Of Endogenous And Pharmacologic Glycosaminoglycans In Preventing Pre-eclampsia

Summary
Pre-eclampsia (PE) is a serious pregnancy complication that affects the well being of the mother and baby. There is no cure for PE except for delivery of the baby. This may result in delivery much earlier than expected causing a very premature baby. This study investigates substances in the placenta that may be responsible for causing PE. If we can understand how these substances cause the problem of PE, we may be able to find better ways of treating or preventing it.
