A unified model of amino acid homeostasis. This project aims to develop a unified model of amino acid homeostasis in mammalian cells and apply it to brain cells. The model will be underpinned by a mathematical algorithm that allows predicting amino acid levels in the cytosol based on fundamental parameters such as transport and metabolism. This project should provide the significant benefit of enabling the prediction of essential functions such as cell growth and survival.

This Project aims to investigate the role of structural and functional cellular components known as microtubules in nervous system regeneration. This Project aims to use innovative approaches in confocal and electron microscopy, genetics, and cell biology, with the expectation of generating new knowledge into nervous system repair. Expected outcomes of this Project include a comprehensive description of how microtubules are rearranged following nervous system injury and the importance of microtubule modifying proteins in promoting regeneration. This should provide significant benefits in our understanding of the cellular mechanisms behind nervous system repair, and offer new approaches for promoting regeneration after injury.Read moreRead less

This project aims to understand the formation of the neural tube; a fundamental tissue structure that generates the brain and the spinal cord. Using interdisciplinary approaches and exploiting recent advances in transgenic and imaging technologies, we expect to reveal the complex interplay between cells and their environment that generates mechanical forces to direct neural tissue formation. Outcomes include knowledge of previously intractable developmental processes, training of future scientists and development of international collaborations. This should provide enhanced imaging capacity, a higher quality scientific workforce and position Australia at the forefront of cell and developmental biology.Read moreRead less
Synergistic nanostimulation of nerve cells using atomic force microscopy technology. The research will develop multifunctional nanoelectrodes for neural prosthetic devices of the future. They will be smaller and more effective, enabling integration with single neural networks in the body, to improve the clinical treatment of severe neurological disorders and loss of sensory (hearing and vision) and motor functions.

Super Resolution Confocal Microscopy Facility. Super resolution confocal microscopy facility:
This project aims to establish a super-resolution confocal microscopy facility with unrivalled resolution, sensitivity and speed. The widespread application of super-resolution microscopy has so far been limited because of the special sample preparation and technical skills required.

Super resolution confocal microscopy facility:
This project aims to establish a super-resolution confocal microscopy facility with unrivalled resolution, sensitivity and speed. The widespread application of super-resolution microscopy has so far been limited because of the special sample preparation and technical skills required. The project aims to provide us with the ability to image thicker samples, such as animal and plant tissue, without these limitations. This would enable us to capture three-dimensional data at both the cellular and tissue level, providing researchers with a level of detail never before seen. The facility may create new knowledge in life science, including visual neuroscience, developmental neurobiology, plant growth, stem cell regeneration, the role of trace metals in physiology, and vaccine and drug development.Read moreRead less
Understanding the changes in brain chemistry associated with schizophrenia. Current drugs for schizophrenia only work in 30% of patients. To develop better therapies, we must understand the changes in the brains of people with the disorder. This research will explore a chemical system in the brain that is changed in schizophrenia and begin to investigate whether counteracting these changes are therapeutically beneficial.

The project aims to understand the molecular mechanisms underlying signal transduction and allosteric modulation of G protein-coupled receptors (GPCRs). Allosteric modulation of proteins is a fundamental process where two distinctly different binding sites are linked through a conformational change. This project will use structural biology, medicinal chemistry and analytical pharmacology to investigate how chemical probes modulate GPCRs at an atomic level, and understand the mechanisms underlying signal transduction. Project outcomes are intended to advance membrane protein crystallography and GPCR biology, and benefit the pharmaceutical industry.Read moreRead less

Summary
Allosteric fingerprinting of G protein-coupled receptor monomers and oligomers. Allosteric modulation describes interactions between distinct, but conformationally linked, binding sites. Research will develop enabling technology using the unique profile, or 'fingerprint', of allosteric modulation at interacting and non-interacting G protein-coupled receptors to probe for receptor complexes within healthy and diseased tissue.
Discovery and characterisation of novel spider-venom peptides targeting the human sodium ion channel Nav1.7. Drugs that selectively block the human sodium ion channel Nav1.7 are likely to be powerful analgesics for treating a wide variety of pain conditions. However, it has proved difficult to obtain selective blockers of this channel. The aim of this project is to determine whether spider-venoms might provide a source of highly selective Nav1.7 blockers.
