Epigenetic Regulation Of Inflammatory Genes In The Fetal Membranes: Role In Term And Preterm Birth

Summary
Preterm birth is the leading cause of death among newborns and the biggest contributor to disability among infants. Here we propose research to define the mechanism that controls the length of pregnancy and is disrupted in preterm birth. Specifically, we will determine what causes the repression of the labour-promoting inflammatory genes in the uterus during pregnancy and what activates them at labour. We will identify new targets for interventions to block or prevent preterm birth.
Immunomodulatory Properties Of Amnion: From Pregnancy To Regenerative Medicine

Summary
Cells from the placenta have been shown to have regenerative capabilities, repairing injured tissues. In this research we aim to explore how the cells do this. In particular we will address how transplanted placental cells talk to the recipient's immune cells to better coordinate tissue repair and prevent scarring. In short, we aim to learn how these cells coordinate immune function during pregnancy to then apply this knowledge to regenerative medicine.
Intraamniotic Delivery Of Antiinflammatory Drugs And Antibiotics For The Prevention Of Preterm Birth

Summary
Inflammation arising from infection in the uterus is a common cause of premature (preterm) birth. Using a pregnant sheep model, plus human preterm membrane studies, we will explore the use of a combination of antibiotics and anti-inflammatory drugs given via intra-amniotic injection to prevent fetal and amniotic inflammation, while protecting mother and baby from unnecessary drug exposure. These studies will lead to the design of clinical trials aimed at preventing preterm birth.
Maternal Recognition Of Fetal Sex In The Regulation Of Labour

Summary
Preterm birth is the largest cause of death in infants and males are more likely to be born preterm than females. We propose that the intrauterine renin-angiotensin system, the activity of which is regulated in a sex-specific manner, plays a critical role in protecting against preterm labour. Our study will further our understanding of the mechanisms of preterm labour and provide new insight into the sex-specific differences in the prevalence of preterm birth.
Cell Therapy For Prevention Of Perinatal Inflammation

Summary
Exposure of babies to infection or inflammation before birth is common and is associated with preterm delivery and illness in newborns. The biggest problem for these babies is lung disease due to inflammation of the lungs before birth and/or in response to lung injury after birth. There is no treatment for the underlying inflammation and no way to prevent or treat the lung disease that it causes. This project will investigate a new stem-cell based treatment for lung inflammation that may prevent ....Exposure of babies to infection or inflammation before birth is common and is associated with preterm delivery and illness in newborns.

Preventing Preterm Lung Disease - A Cell Therapy Approach.

Summary
Due to improvements in medical care, the survival of very premature babies has greatly improved over the past 20 years. However, many of these children are surviving with disability due to severe chronic lung disease of prematurity. Currently, there are no effective treatments for this lung disease. This project explores the use of placental stem cells as a lung repair and regeneration therapy - a therapy that can be given to the baby in the days immediately following its birth.
The Bcl-2 family of proteins is crucial for apoptosis (a form of programmed cell death) regulation. They target the mitochondrial outer membrane where they interact to determine cell fate. We will evaluate the membrane interactions of the Bcl-2 proteins in complementary biophysical and cellular experiments to redefine our understanding of the mechanism of apoptosis and provide new avenues for the development of compounds to selectively modulate diseases in which apoptosis is unregulated.
Myo1b Bridges The Actin-membrane Interface During Osteoclastic Bone Resorption

Summary
Osteoporosis is a debilitating bone disease which features progressive bone loss. Bone loss (resorption) is driven by the bone resident cell the osteoclast. Identifying molecules that regulate bone resorption by osteoclasts is a crucial first step towards developing new targets for theraputic intervention. This proposal explores the role of Myo1b, a novel protein that appears to facilitate osteoclastic bone resorption and thus represents an attractive new candidate to target bone loss.
