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.

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.
Multimodal Electrically Conducting Bionic Implant For Long-distance Oriented Axonal Regeneration

Summary
Neurotrauma, defined as an injury to the central nervous system, is a debilitating medical condition affecting over 3 million people annually worldwide. Loss of function following injury is largely due to the limited potential of nerve cells to regenerate. I will develop a bionic platform that conducts electrical signals and delivers growth promoting proteins thereby enhancing the directed regeneration of nerve cells necessary to bridge the gap caused by the injury and restore organ function.
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.
The Role Of Innate Immune Responses In Cardiac Muscle Regeneration

Summary
Heart attack is a life-threatening disease that damages heart muscle. Zebrafish can naturally restore lost heart muscle after injury, providing a model to understand mechanisms of heart regeneration. Here, we will explore previously uncharacterized events involved in heart regeneration, with particular focus on the immune response. We will study how immune responses are involved in heart muscle regeneration in zebrafish to find new insights for repairing damaged muscle in the human heart.

Summary
Periodontitis is a prevalent dental condition that often leads to premature tooth loss. This project investigates the regenerative potential of periodontal ligament stem cells. It aims to identify novel markers to facilitate the isolation of these cells and to elucidate key factors and mechanisms for periodontal regeneration to occur. These findings will help to improve the predictability of current regenerative therapies and develop a successful treatment strategy for periodontitis.

Summary
Muscular Dystrophy is the most common lethal inherited disorder of children. Within dystrophic patients skeletal muscle fibres undergo cycles of muscle breakdown and regeneration until the regenerative response is exhausted, leading to a progressive muscle wasting. Regeneration of skeletal muscle is controlled by a specialised set of stem cells termed satellite cells that are activated to produce new muscle fibres in response to injury.

Within dystrophic patients skeletal muscle fibres undergo cycles of muscle breakdown and regeneration until the regenerative response is exhausted, leading to a progressive muscle wasting. Regeneration of skeletal muscle is controlled by a specialised set of stem cells termed satellite cells that are activated to produce new muscle fibres in response to injury. As such satellite cells have been the targets of intense investigation for the development of cell based therapies for muscular dystrophies. We have developed a new vertebrate animal system in which to analyse muscular dystrophy and the control of satellite cell function, the zebrafish. We have shown that a mutation in a gene responsible for causing Duchenne Muscular Dystrophy in humans also causes a similar disease in Zebrafish. Zebrafish are an embryologically and genetically tractable model system in which to study muscle cell biology. The ability to visualise muscle growth within an optically transparent embryo and larvae, coupled with a large number of mutations affecting muscle patterning and growth suggest that it is a suitable model to explore muscle maintenance. The specific aims of this proposal are to determine in our new dystrophic zebrafish model, how regeneration controls the onset and pathology of muscle fibre loss. We wish to determine if muscle stems cells analogous to those known to function in mammalian muscle can be detected in zebrafish in normal and dystrophic muscle. We then plan to identify novel genes controlling muscle growth and regeneration through the genetic and embryological advantages that zebrafish as a model organism provide. We hope this will lead to a better understanding of how muscle stem cells are generated and are activated in muscular dystrophy and we hope this will open new avenues for muscle stem cell based therapies of the disease.Read moreRead less
Identification And Characterization Of The Molecular Mechanisms Of Cardiac Muscle Regeneration Regulated By The Epicardium In Zebrafish

Summary
Heart attack is a life-threatening disease that damages cardiac muscle. The human heart cannot create new muscle after the damage, which partly contributes to the high morbidity and mortality of this disease. Unlike humans, zebrafish, a small tropical freshwater fish, can naturally create cardiac muscle after injury. In this project, we will understand at the molecular level how zebrafish regenerate cardiac muscle, and provide insights for repairing damaged muscle in the human heart.
