Multimodal Woven BioPolymer Fibre Conduits For Remodelling Damaged Peripheral Nerve

Summary
Damage to peripheral nerve arises as a result of trauma or disease ranging in severity from mild to severe incapacitation. Currently surgeons remove healthy nerve from individuals with nerve damage to repair more important priority nerves. We aim to create an effective implant for nerve repair that totally degrades leaving behind the regenerated nerve. This will eliminate the need for nerve harvesting as well as restoring lost nerve function in individuals with nerve injury.
Nanoparticle Based Neurotrophin Delivery To Promote Directed Neurite Growth And Auditory Nerve Rescue Following Deafness

Summary
The cochlear implant provides hearing information to the severe-profoundly deaf by electrically stimulating the auditory nerves of the inner ear. Deafness causes these auditory nerves to gradually degenerate leaving fewer nerves for the cochlear implant to stimulate. We propose to reverse this neural degeneration by delivering therapeutic drugs to the inner ear using tiny nanoparticles. This novel technology is expected to have application in other areas of neural degenerative disease.
Molecular And Cellular Mechanisms Of Vertebrate Brain Development

Summary
The essential steps in forming a normal functioning brain occur during life as an embryo. If these processes go haywire, there can be serious repercussions for life after birth. This project seeks to understand how the brain forms during embryonic stages so that better treatments and procedures can be developed to deal with developmental problems.
Functional Neurogenesis In The Injured Neocortex Of The Nonhuman Primate

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.
The Use Of Soluble Antagonists Of EphA4 In Spinal Cord Injuries

Summary
Permanent and limited recovery of function following spinal cord injury is a direct result of the lack of nerve regrowth through the injury. Our preliminary data suggest that antagonising the effects of EphA4, a protein involved in brain development, leads to substantial functional recovery simultaneous with nerve regrowth. In addition to designing new, more effective blockers of EphA4, we will study the signalling pathways that EphA4 activates to inhibit nerve regrowth.
Long-term Nerve Damage In Cancer Survivors: Identification Of Risk Factors And Optimal Assessment Strategies

Funding Amount

Summary
Nerve damage following chemotherapy treatment leads to early treatment cessation and long-lasting disability, developing with commonly used chemotherapies. There is a critical need to understand the mechanisms, optimize clinical assessment and develop interventions to prevent nerve damage. This project is designed to detect the impact of long-term nerve damage in cancer survivors and develop a risk profile based on clinical, neurophysiological and genetic factors.

Summary
There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue. First, the nerve cells that are damaged have to be encouraged to regrow - typically this regrowth is inhibited in the brain; and second, this regrowth has to be directed so that the correct connections are re-established. This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can ....There are, at least, two major obstacles that have to be overcome in the design of therapies to assist the repair of injured brain tissue.

This project will begin to unravel some of the mechanisms that nerve cells use to wire up together during development. This information can be used to assist in trying to modulate and facilitate directed regrowth following injury.Read moreRead less
Chronic neck pain is difficult to treat and can result in a complex set of symptoms, including dizziness, disturbed vision, and exaggerated pain responses in the upper torso and arms. Thus, there is a need to develop new treatments for this debilitating condition. This project will study how damage to structures in the neck alters the excitability of nerve cells in the upper cervical spinal cord. The results will provide a foundation for development of therapies to treat chronic neck pain.

Summary
The olfactory (smell) system is a unique part of the nervous system; nerve cells are generated throughout life and it can regenerate even after injury. It therefore provides an excellent model for examining the growth, development and maintenance of nerve cells. This project will examine the effects on the organisation of the olfactory system when some guidance signals are altered. Information we obtain about how this system develops and regenerates may be useful in treating brain disorders and ....The olfactory (smell) system is a unique part of the nervous system; nerve cells are generated throughout life and it can regenerate even after injury.

This project will examine the effects on the organisation of the olfactory system when some guidance signals are altered. Information we obtain about how this system develops and regenerates may be useful in treating brain disorders and spinal injuries In the current project we will examine the effects of specific nerve cell guidance molecules by generating transgenic mice that produce these molecules only in the olfactory system. We can then determine what changes occur to the nerve cells when these extra molecules are produced. The results of these experiments will provide important information on the the initial growth and targeting of these nerve cells which may have implications for regeneration of these as well as other nerve cells.Read moreRead less
