Summary
Bacterial membrane remodelling and the interaction with peptides. This project aims to elucidate the fundamental mechanism of lipid remodelling in Gram-negative outer membrane, which is critical both in preventing noxious compounds and evading host immune defence. For the first time, the complex interplays between bacterial cellular metabolism and membrane remodelling will be defined through systems pharmacology, and the precise membrane-peptide interaction will be examined by computational and ....Bacterial membrane remodelling and the interaction with peptides. This project aims to elucidate the fundamental mechanism of lipid remodelling in Gram-negative outer membrane, which is critical both in preventing noxious compounds and evading host immune defence. For the first time, the complex interplays between bacterial cellular metabolism and membrane remodelling will be defined through systems pharmacology, and the precise membrane-peptide interaction will be examined by computational and biophysical approaches. Novel knowledge will be generated to improve our understanding on how bacteria remodel their outer membrane in response to environmental stress. This will benefit the future design of much-needed antimicrobial strategies including products and technologies to target bacterial membrane. Read moreRead less

Summary
Targeting bacterial superbugs: novel approaches for optimisation of antibiotic combinations and resistance prevention. This project will elucidate the mechanistic basis to optimally combine available beta-lactam antibiotics to prevent resistance of gram-negative 'superbugs'. The interdisciplinary project will substantially contribute to solving the global crisis due to multidrug-resistant bacteria and inform the design of effective new antibiotics.

Summary
Using toxins to manipulate the gating of voltage-gated sodium channels. The project aims to investigate how sodium channel subtypes contribute to the excitability of sensory neurons by utilising venom-derived peptides that specifically target and alter the function of these channels. This project expects to generate new knowledge in the area of neuroscience using an interdisciplinary approach including synthetic peptide chemistry, pharmacology and electrophysiology. Expected outcomes of this pro ....Using toxins to manipulate the gating of voltage-gated sodium channels.

Summary
Developing the toolbox of compounds that target acid-sensing proteins. This project aims to examine the interaction between acid-sensing proteins and their modulatory compounds. Animals, including humans, must sense changes in environmental acidity to successfully interact with the surrounding world. Expected outcomes of the project include a better understanding of which regions of these proteins detect acidity, and to develop new compounds that modulate the proteins’ function.

Animals, including humans, must sense changes in environmental acidity to successfully interact with the surrounding world. Expected outcomes of the project include a better understanding of which regions of these proteins detect acidity, and to develop new compounds that modulate the proteins’ function. This would advance our fundamental knowledge in the physiological process of acid sensing. This expects to provide significant benefits, by aiding the potential development of agrochemicals and pain-relieving medications that regulate acid-sensing protein function, resulting in economic benefit to Australia via these new products.

Summary
Endogenous bone regenerative technique to repair hard tissue defects in congenital craniofacial clefts. This project aims to develop an endogenous bone regenerative technique to repair the bony defects in congenital craniofacial clefts, through stimulating patients' latent self-repair mechanisms and reviving their innate capacity for regeneration. The novel technique would replace the existing and controversial surgical bone grafting method.

Summary
Illuminating drug activity in the brain with nanocrystalline beacons. The project focuses on developing technologies to understand the activity of drugs and precisely locate their target sites in the brain. Novel nanocrystalline beacons and ultrahigh-sensitivity optical imaging technology developed in the project have the aim to help visualise opioid and other related drug molecules over extended periods, which is impossible with current methods.

Novel nanocrystalline beacons and ultrahigh-sensitivity optical imaging technology developed in the project have the aim to help visualise opioid and other related drug molecules over extended periods, which is impossible with current methods. Quantifying drug target distribution in the brain and imaging their dynamics on a single molecule level will shed light on drug-target interactions.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.

Summary
Molecular insights into the allosteric regulation of opioid receptors. Allosteric regulation is the biological process by which molecules bind to proteins someplace other than their active site, regulating their activity. Proteins on the cell surface called membrane receptors can be allosterically regulated to fine-tune the response of cells to the environment. This project aims to investigate how small molecules regulate receptor activity at a molecular level, using opioid receptors as an exemp ....Molecular insights into the allosteric regulation of opioid receptors. Allosteric regulation is the biological process by which molecules bind to proteins someplace other than their active site, regulating their activity. Proteins on the cell surface called membrane receptors can be allosterically regulated to fine-tune the response of cells to the environment. This project aims to investigate how small molecules regulate receptor activity at a molecular level, using opioid receptors as an exemplar system. I will use an interdisciplinary approach that combines structural biology, medicinal chemistry, analytical pharmacology, and cell biology. The knowledge gained from these studies will advance fundamental understanding of receptor function and can lay the foundation for future drug discovery efforts.Read moreRead less
