Summary
A major source of repair inhibition after brain injury is debris from dying cells, which contains proteins that hinder repair. This project will examine the expression of these proteins in a clinically-relevant model of ischemic stroke and determine if blocking the effect of these proteins neutralises their repair-inhibiting properties. If successful, there is likelihood that this drug, and method of delivery, could be translated into the human for treatment following an ischemic stroke.
Next Generation Cybernetics: Long Term Carbon Fibre Dual Stimulation / Recording Electrode Arrays For Closed Loop Neural Implants

Summary
Electrodes implanted in the brain have enormous potential for treating a range of conditions from epilepsy to control of prosthetics for patients with limb loss. Currently, the electrodes used in such system fail rapidly because they are rejected by the body. We aim to use diamond with ultra-fine carbon fibre electrodes to make arrays that are invisible to the human immune system. Such arrays will function for the lifetime of the patient without needing replacement.
Defining Role Of Inflammatory Signals In Enhancing Motoneuron Regeneration

Summary
Spinal cord injury is a devastating event that has a life-long impact on the patient’s life with wide-reaching social and economic effects. In this proposal we examine how inflammatory signals boost neuronal regeneration after injury. Furthermore, we define how new neurons are able to integrate into existing spinal circuitry. Out work provides critical insight and hold keys to unlocking strategies for future restorative therapies in the brain or spinal cord.
Knowledge, Identification And Exploitation Of Dopaminergic Axon Guidance Cues Will Improve Cell Replacement Therapy For ParkinsonÍs Disease.

Summary
Many obstacles exist for cell transplantation in ParkinsonÍs Disease; namely poor graft survival, restoration of appropriate circuitry and adequate nerve fiber growth from new cells. Using knowledge of how neural circuits are established during fetal development, we will attempt to recapitulate these events following transplantation. Further, we will identify new and novel cues in regulating the connectivity and growth of these nerve fibers.
Enhancement Of Newborn Neuron Survival To Promote Repair Following Adult Brain Injury

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.

Pre-Clinical Studies Towards Cell-Based Approaches For Cortical Repair.

$739,901.00
Summary
This project seeks to determine whether brain cells that die after stroke can be functionally replaced using cells grown in the laboratory from human stem cells. Current therapies for stroke aim to limit the damage but do not allow for actual recovery of brain function. By growing turning stem cells into specialised cells that match the ones lost after stroke, this project aims to restore motor function by transplanting these cells into the injured brain.
Pre-clinical Steps Towards A Stem Cell Therapy For Parkinson's Disease.

Funding Amount
$1,179,594.00
Summary
A promising experimental therapy for Parkinson's disease is the use of stem cells that in order to replace the cells lost during the disease process. A challenge for this approach is that upon transplantation into the brain, in addition to the therapeutic cell types, there will also be unwanted cell types such as those that can form tumours. This proposal seeks to establish a novel strategy for removing those cells prior to transplantation.

Brain trauma and neuro degenerative diseases are prevalent conditions that cause life-long impact and severe disability. Currently there are no therapeutical options available and the prognosis for recovery is very poor. We recently determined the crucial and beneficial role of inflammation in neural regeneration. The inflammatory signals that initiate regeneration are not known.

Summary
This research aims to develop a procedure that allows for the safe and effective use of stem cells as a therapy for Parkinson’s disease. It is based on the concept that new dopamine neurons, generated from stem cells, can be implanted into the brain of the patients in order to replace those lost to the disease, thereby improving motor function.

Summary
The inability of the adult heart to regenerate following a heart attack is a major contributor to the burden of heart disease in the developed world. We have recently discovered that, for a brief period after birth, the newborn heart can completely regenerate itself following injury. Understanding how and why the heart loses this remarkable capacity for regeneration shortly after birth may hold the key for developing cardiac regenerative therapies.
