Summary
Limited nerve regeneration is the main obstacle for recovery from spinal cord and brain injuries. Understanding the cellular and molecular mechanisms underlying axonal regeneration is an essential step toward the development of novel effective therapies to enhance this process. In this proposal, we use the powerful molecular and genetic tools available for the small nematode worm C. elegans to identify and study axonal regeneration and discover the key molecules involved.

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.
Deciphering The Mechanisms Underlying LRP-mediated Axon Guidance

Summary
Nerve damage can develop post injury or disease and are often very debilitating, slow to heal and cause increased pain. Our work aims to examine a new class of molecules that we show can activate selected fat-receptors on nerve cells to guide the growth of regenerating nerves. We will determine how these receptors function with the aim of developing a novel class of therapeutics directed at healing nerve damage.
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
Injuries to the nervous system can cause lifelong disabilities due to ineffective repair of the damaged nerve fibres. Our previous research has identified a highly efficient mechanism that occurs in nematode worms that allows severed nerves to fuse back together. We will now focus on understanding precisely how this mechanism works, and investigate its utility in repairing nerves that don’t normally utilise this repair mechanism.

Summary
Conditions such as Alzheimer�s and Huntington�s diseases, as well as stroke, represent a major burden of disease in Australia. One goal of modern neurobiology is to harness the brain's ability to make new neurons so that we can replace those damaged by disease or injury. We will investigate how an important developmental molecule, Neogenin, promotes the production of new neurons in the adult brain. A second goal is to show that Neogenin can be activated to promote the repair of the damaged brain ....Conditions such as Alzheimer�s and Huntington�s diseases, as well as stroke, represent a major burden of disease in Australia.

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.

Using nanostructured scaffolds to understand and engineer neuronal circuits. This project aims to understand the formation of neuronal circuits in the brain. While the role of biochemical features in the brain is well understood, it is not clear how the biophysical properties of the brain affect circuit formation. The outcomes of this project will improve our understanding of neuronal circuit formation as well as provide design rules for creating scaffolds to repair neuronal circuits after brain ....Using nanostructured scaffolds to understand and engineer neuronal circuits.
