Summary
We aim to deliver a radical new precision intervention for peripheral nerve repair to improve the lives of people with peripheral nerve damage. Drawing from our recently awarded work on 'electric neural tissue engineering', we will pre-clinically test our invention of a unique clinically-amenable electric nerve-guide (e-nerve-guide), designed to act as a protective nerve conduit and wirelessly electrically-stimulate damaged nerves for their regeneration and restoration of function.
Axonal Regeneration And Degeneration: Cellular And Molecular Mechanisms

Summary
Understanding how to repair of nerve damage following a traumatic injury, a vascular accident, or a degenerative condition, is essential to develop novel effective treatments. We have identified, in a simple genetic model system, the molecular mechanisms that allow a transected nerve to be repaired by reattachment of its two separated fragments. This 'axonal fusion' process is a highly promising innovative approach that can be exploited to restore the original neuronal circuit.

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.

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.
Nerve growth factors are essential to promote nerve regeneration and are potential drugs for the treatment of nervous disorders such as spinal cord injury. Our recent result demonstrates that the precursor form of the nerve growth factor brain derived neurotrophic factor (proBDNF) is detrimental to an injured nervous system and can cause nerve degeneration. This project further investigates the phenomenon in order to promote treatment of spinal cord injury.

Summary
Partial or complete deafness affects 11% of Australians and has great personal, social and economic cost . Worldwide, over 60,000 deaf people can now understand spoken language because of the Bionic Ear. However, after prolonged deafness, the nerves in the ear that the BIonic Ear stimulates die, reducing hearing quality. Our research tests whether biological interventions with nerve growth factors and nerve stimulation can preserve nerve function and improve hearing with the Bionic Ear.
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.

The project uses a new approach that allows, for the first time, electrical activity to be recorded and analysed from the very fine nerve endings of nerves whose activation results in painful sensations. Using this technique the mechanisms by which substances released in damaged and inflamed tissues lead to discharge of action potentials and the sensation of pain will be investigated.

Using this technique the mechanisms by which substances released in damaged and inflamed tissues lead to discharge of action potentials and the sensation of pain will be investigated. In particular the project investigates the role of a population of sodium ion selective pores (channels) that are uniquely expressed in pain sensing nerves. These channels have been hypothesised to play an important role in determining the behaviour of these nerves. In addition, the project investigates how some substances released in inflamed tissues sensitize pain sensing nerves, causing them to more readily discharge action potentials. This change is the major cause of pain associated with inflammatory diseases such as arthritis. In summary, the proposed project will provide new insight into how pain sensing nerves function. This knowledge is essential for the development of more effective strategies for treating pain resulting from inflamed and damaged tissue.Read moreRead less
