Defining the cellular impacts of protein aggregation in neurodegenerative disease with an aggreomics platform. The brain disease Huntington’s is caused by abnormally shaped proteins that assemble into toxic clusters. This project will design new bioprobes to track how these clusters form and cause damage to cells. This strategy will also provide new opportunities for discovering novel therapeutic targets.
Roles of the kynurenine pathway in physiological and pathological brain function. This project will aim to study the metabolism of the essential amino acid tryptophan in the brain and its involvement in diseases including multiple sclerosis and brain tumours.
Visualising neuron-glia interactions in the injured central nervous system. The adult brain and spinal cord recovery poorly from injury. Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain. This project will use the latest, cutting-edge mic ....Visualising neuron-glia interactions in the injured central nervous system. The adult brain and spinal cord recovery poorly from injury. Attempts to overcome this problem include methods to promote the intrinsic regenerative capacity of injured neurons, and modulating the inhibitory extracellular environment to become permissive to regeneration. The goal of this project is to investigate an endogenous regenerative mechanism in the injured brain. This project will use the latest, cutting-edge microscopy techniques to visualise whether the endogenous astrocyte protein metallothionein can promote regeneration in the injured nervous system of living zebrafish. The successful outcomes of this project will provide significant insight into understanding how the brain responds to injury.Read moreRead less
Deciphering the cellular defences against aggregating proteins in human disease. Cells have inbuilt defences for coping with proteins that bend into abnormal sticky shapes that form toxic clusters. In many diseases, including Huntington's, the clusters severely damage nerve cells. This project will identify the genes and mechanisms cells use to protect themselves from toxic clusters, which could provide new therapeutic targets.

Stem Cells Australia. Despite progress in stem cell research, scientists do not understand how stem cells “decide” what to become. Stem Cells Australia will draw upon strengths within Australia’s premier stem cell research universities and institutes. This collaboration between leading bioengineering, nanotechnology, stem cell and advanced molecular analysis experts, will fast-track efforts to deliver a fundamental understanding of the mechanisms of stem cell regulation and differentiation, and ....Stem Cells Australia. Despite progress in stem cell research, scientists do not understand how stem cells “decide” what to become. Stem Cells Australia will draw upon strengths within Australia’s premier stem cell research universities and institutes. This collaboration between leading bioengineering, nanotechnology, stem cell and advanced molecular analysis experts, will fast-track efforts to deliver a fundamental understanding of the mechanisms of stem cell regulation and differentiation, and the ability to control and influence this process. Stem Cells Australia will deliver new methods for stem cell propagation and manipulation, new translational technologies for therapeutic applications, and will prepare Australia’s future stem cell scientific leaders.Read moreRead less
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.

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 gender differences in pain: Cellular therapies for animal pain. Understanding gender differences in pain: Cellular therapies for animal pain. This project aims to relieve chronic pain in animals and lay the foundations for future human therapies, using molecular assays, cell technologies and immune/hormonal pain generators.

Understanding gender differences in pain: Cellular therapies for animal pain. This project aims to relieve chronic pain in animals and lay the foundations for future human therapies, using molecular assays, cell technologies and immune/hormonal pain generators. Chronic pain affects females more than males. Establishing the fundamental mechanism in pain, the role of immune signalling and molecular mediators will enable true pain-modifying treatments that address pivotal triggers in both genders. This project will then use specially selected stem cells separately targeting arthritic male and female pain and demonstrate novel veterinary chronic pain treatments. Expected outcomes are more effective gender-targeted treatments of pain and the realisation of economic value of molecular assays and cell technologies.Read moreRead less
The role of actin in driving bulk endocytosis in neurons and neurosecretory cells. Synaptic release of neurotransmitter is essential for neuronal communication. Following fusion, synaptic vesicle membrane is incorporated into the plasma membrane and retrieved by endocytosis to recover both lipids and essential vesicular proteins. The project will characterise how the actin cytoskeleton perform this function.
How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misf ....How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misfolded proteins during ageing, within the nervous system of a living animal. Expected outcomes of this project will generate new knowledge of brain physiology and ageing relevant to all animals. This should provide significant benefits, such as a greater understanding of long-term brain functions including memory.Read moreRead less
