Summary
Currently, despite cord blood transplantation, most leukemia patients will ultimately die of disease relapse. Therefore, my proposal is focused on improving the effectiveness of cord blood transplantation by further infusion of gene modified umbilical cord derived immune blood cells designed to specifically target and lyse residual leukemia tumor cells. This novel approach this will decrease disease relapse and lead to better patient survival following cord blood transplant therapy.
The Potential Of Cord Blood Stem Cells To Reduce Neuroinflammation

Summary
Cerebral palsy (CP) is the most common cause of physical disability in children and it is well recognised that the brain injury that underlies CP occurs during pregnancy or around the time of birth. Stem cells isolated from umbilical cord blood offer a promising new therapy for children with CP. This proposal will explore the mechanism of how cord blood stem cells can reduce brain inflammation and damage caused by hypoxia-ischemia, an event known to lead to cerebral palsy.

Summary
The immune system has a series of checks and balances in place to distinguish foreign bodies from normal, or self-antigens. In healthy individuals this prevents the immune system from attacking the cells and tissues of the body, food proteins, and the beneficial bacteria of the gut. However in autoimmune disease the system becomes imbalanced, allowing reactions to benign antigens, causing diseases such as diabetes, asthma and rheumatoid arthritis.

In healthy individuals this prevents the immune system from attacking the cells and tissues of the body, food proteins, and the beneficial bacteria of the gut. However in autoimmune disease the system becomes imbalanced, allowing reactions to benign antigens, causing diseases such as diabetes, asthma and rheumatoid arthritis. One of the key players in the maintenance of a healthy immune system is a specialized set of T cells known as T Regulatory cells. These cells are rare, at 1-4% of all T cells, yet are potent modulators of other T cells, and can prevent the activation of a T cell if it is reacting to a self-antigen. If they can control the cause of autoimmune disease, and patient Treg cells can be manipulated, it may be possible to use them therapeutically. Recently the switch that is required to generate regulatory cells was identified from patients with a rare autoimmune disease called Immunodysregulation, polyendocrynopathy, enteropathy, X-linked syndrome or IPEX. A mouse disease, Scurfy, with similar symptoms, is caused by the same mutations. The mutated gene encodes a protein, FoxP3, and this protein is able to bind to other genes in T cells and regulate their function. Without this protein, there are no T regulatory cells, resulting in autoimmune disorders. At this time there is very little known about how the FoxP3 gene is able to make a T cell become a regulatory T cell, and nothing is known about the genes that are turned off and on to facilitate this. If we can understand better the role of this protein, FoxP3, in the generation and maintenance of T cells with regulatory function, we may better be able to diagnose and treat autoimmune diseases, and this knowledge will have broad application to many autoimmune disorders.Read moreRead less
Does Placental Transfusion Prevent Death And Disability In Very Preterm Infants? Childhood Follow Up In The NHMRC Australian Placental Transfusion Study.

Summary
A million babies are born before 30 weeks gestation worldwide each year. Many die or face a lifetime of disability. Enhancing placental transfusion in these infants by deferred clamping of the umbilical cord (DCC) is a simple procedure that may reduce mortality and major disability in childhood. The Australian Placental Transfusion Study (APTS), the largest ever RCT of deferred clamping, will follow up 1200 children born preterm to evaluate if DCC has childhood benefits at 2 years age.
Blood-Spinal Cord Barrier Structure And Function In Syringomyelia

Summary
Syringomyelia is a disorder in which a fluid-filled cyst forms within the spinal cord. These cysts expand over time resulting in paralysis or even death. Syringomyelia occurs in association with spinal cord injury and a number of congenital conditions. In this project we aim to investigate the underlying cause of cyst formation, which is currently unknown. It is hoped that these studies will improve our understanding of cyst formation and facilitate development of better treatment strategies.
Injury to the developing brain, whether sustained during pregnancy or at birth, is the underlying cause of many cognitive and motor disabilities, including cerebral palsy. This project will identify the cellular pathways that cause developmental brain injury in preterm and term infants, and then administer umbilical cord blood stem cells at different timepoints to assess their efficacy at reducing brain injury. This project will inform treatment with cord blood stem cells in high risk infants.
