Central Nervous Pathways For The Sympathetic Control Of Immune Function
Funder
National Health and Medical Research Council
Funding Amount
$300,741.00
Summary
The nervous system regulates immune system function by a special set of nerves that are part of the sympathetic nervous system. This project aims to work out which brain pathways control them.
The brain regulates body temperature by a series of mechanisms, including the control of how much blood flows to the skin to lose or retain heat. The project aims to locate the brain temperature receptors and brain pathways that do this, using an animal model, the rat. At present they are not known.
Stem Cell Treatment For Neonatal Hypoxic Ischaemic Encephalopathy

Funding Amount
$954,195.00
Summary
Hypoxic-ischaemic encephalopathy occurs when the fetus receives inadequate oxygen in labour and many babies die or have brain damage. Stem cell therapy might save these babies from brain damage but there are many unknowns, such as which stem cells to use and how many. Through our skills in stem cells and measuring the rescued brain following injury, we will determine the necessary details for the most effective stem cell therapy to be ready to immediately test the treatment in a RCT in babies.
Nfib Regulates Glial Differentiation During Development And Disease Via Repression Of The Key Epigenetic Protein, Ezh2

Funding Amount
$572,912.00
Summary
Glial development is critical during development, and unrestrained proliferation of glial stem cells in the adult can lead to deadly brain cancers such as glioma. At present there is no cure for glioma and current treatments do not significantly delay tumour progression. Nfib is a transcription factor that may prevent tumour growth through cellular differentiation. We will investigate the role of Nfib during development and in the pathogenesis of glioma and its potential as a therapeutic target.
Functional Neurogenesis In The Injured Neocortex Of The Nonhuman Primate

Funding Amount
$966,048.00
Summary
Research over the past couple of decades has revolutionised our understanding of the capacity of the brain to generate new cells, especially following an injury. However, what does remain controversial is whether this phenomenon occurs in all areas of the brain, especially following a severe traumatic brain injury or stroke. This project will examine whether the outer surface of the brain has the potential to generate new cells following a brain injury and whether they become functional.
Enhancement Of Newborn Neuron Survival To Promote Repair Following Adult Brain Injury

Funding Amount
$555,780.00
Summary
Following brain damage tissue needs to be rebuilt and newborn nerve cells need to survive. Identification of factors that enhance the numbers and promote the survival and appropriate integration of newborn nerve cells is therefore important and over the last few years we have identified two regulatory factors that are prime candidates to enhance numbers and survival of newborn neurons following injury: the Rho pathway and suppressor of cytokine signalling-2, which we will test for effectiveness ....Following brain damage tissue needs to be rebuilt and newborn nerve cells need to survive.

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.
Mechanisms Of PTEN Regulation By Ndfip1 And Their Biological Consequences For Neuron Survival During Brain Injury
Funder
National Health and Medical Research Council
Funding Amount
$686,640.00
Summary
We have discovered a new protein (Ndfip1) that protects brain cells from death after brain injury from trauma and stroke. We will investigate why this protein is activated only in some, but not in other, brain cells after injury. In this application, we will study the mechanisms behind neuron protection, and use this information to explore how to increase the number of brain cells activating Ndfip1.
Using Direct Reprogramming To Generate And Rejuvenate Haematopoietic Stem Cells
Funder
National Health and Medical Research Council
Funding Amount
$1,026,313.00
Summary
One of the greatest promises of regenerative medicine lies in our ability to reprogram any cell type of the body into any other cell type. Transdifferentiation is the conversion of one adult cell type to another and it is believed to be the next frontier in regenerative medicine therapies since it can be used in vivo for the direct conversion of one cell type into another. The outcomes of this grant will push the limits of these technologies to generate new regenerative medicine strategies.
Generating Haematopoietic Stem Cells From Human Pluripotent Stem Cells

Funding Amount
$872,215.00
Summary
Blood stem cell transplantation is a vital therapy for patients with leukaemia following chemotherapy or for patients with bone marrow failure. Because many patients lack a donor, there is a need for an alternate source of stem cells. Using a new approach that we have developed, our laboratories will make blood stem cells from human pluripotent stem cells that will treat patients needing a transplant.
