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.
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

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.

Summary
Molecular insight into allosteric modulation of G protein-coupled receptors. 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 prob ....Molecular insight into allosteric modulation of G protein-coupled receptors. 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
Biosynthesis, folding and modification of conotoxins. Disulfide-rich peptides represent a diverse family of bioactive molecules which have been developed as drugs for the treatment of severe pain. This project seeks to understand their biosynthesis and how their functional diversity is generated. Such information will assist the translation of more of these novel peptides into new drugs.

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.
Awaking quiescent neural stem cells. This project aims to generate new knowledge in the area of the evolutionary size of animals and plants, which is determined by intrinsic cell regulation and is constrained by nutrient availability. Brain size is perhaps the most profound example of this. Brain size regulation is underpinned by control of proliferation of neural stem cells (NSCs). Using Drosophila NSCs, the project will examine how nutrients impact on NSC quiescence versus activation, a key ch ....Awaking quiescent neural stem cells. This project aims to generate new knowledge in the area of the evolutionary size of animals and plants, which is determined by intrinsic cell regulation and is constrained by nutrient availability. Brain size is perhaps the most profound example of this. Brain size regulation is underpinned by control of proliferation of neural stem cells (NSCs). Using Drosophila NSCs, the project will examine how nutrients impact on NSC quiescence versus activation, a key characteristic of stem cell control throughout evolution. This will increase our understanding of how energy metabolism and nutrition influence organ size control in multicellular organisms, by determining how organs communicate with each other to convert nutrient signals to action stem cell proliferation.Read moreRead less
Regulation of neurite outgrowth by an inhibitor of PI3K signalling. PIPP is an enzyme which inhibits important cellular functions such as cell maturation. We have shown the amount of PIPP is increased in Alzheimer's disease brains. This project will characterise the mechanisms by which PIPP regulates brain cell function to identify how PIPP may be acting to exacerbate Alzheimer's disease development/progression.
