Summary
A facility for ex-vivo molecular imaging. The facility will allow a consortium of Australian researchers to create an integrated facility for imaging biological receptors in tissue, bringing together laboratory, radiochemistry and imaging expertise. Digital data at each site will be able to be viewed and analysed remotely.
Toxins from Down Under: Novel tools to understand and modulate ion channels. Venoms are complex secretions containing biologically active components that have evolved over millions of years to specifically target the nervous systems of predators and prey. Two novel classes of toxins from snake and plant venoms that act on voltage-gated sodium channels, key proteins that regulate neuronal excitability, were recently identified by the research team. The project aims to develop and apply state-of-t ....Toxins from Down Under: Novel tools to understand and modulate ion channels. Venoms are complex secretions containing biologically active components that have evolved over millions of years to specifically target the nervous systems of predators and prey. Two novel classes of toxins from snake and plant venoms that act on voltage-gated sodium channels, key proteins that regulate neuronal excitability, were recently identified by the research team. The project aims to develop and apply state-of-the-art chemical, structural and biological techniques to unravel the molecular mechanisms through which these novel toxin classes act at their targets. Insights gained from this project will help identify and develop novel channel-modulating molecules that may have applications as neuroscience tools, diagnostics or drugs.Read moreRead less
The potential of membranes – peptide engineering to modulate ion channels. This project aims to develop a platform technology to identify new and selective sodium channel inhibitors based on ultra-stable venom peptides that can interact with and cross membranes. Sodium channels are involved in almost all aspects of human physiology. The ability to selectively inhibit individual sodium channel subtypes and to understand what drives peptides' ability to cross membranes would be a major achievement ....The potential of membranes – peptide engineering to modulate ion channels.

This project’s proposed technology could be translated into new knowledge relevant to the biotechnology industry.Read moreRead less
Defining a new family of sodium channel accessory proteins. Voltage-gated sodium channels are key proteins that function as multi-subunit complexes to regulate neuronal excitability. The project aims to investigate the structure and function of a novel family of accessory subunits by utilizing a class of toxins, derived from the giant Australian stinging tree, that directly binds to these proteins to modulate sodium channel function. The project aims to generate significant new knowledge on the ....Defining a new family of sodium channel accessory proteins.

Nicotinic receptor structure and function probed with conotoxins. Nicotinic receptors are intrinsic membrane proteins that play a role in communication in excitable cells, particularly in the nervous system. The primary goals of this project are to define the structural and functional determinants of nicotinic-conotoxin interactions at a molecular level, and develop new selective probes that advance neurophysiological research. The diversity and distribution of nicotinic receptor subtypes being ....Nicotinic receptor structure and function probed with conotoxins.

The primary goals of this project are to define the structural and functional determinants of nicotinic-conotoxin interactions at a molecular level, and develop new selective probes that advance neurophysiological research. The diversity and distribution of nicotinic receptor subtypes being uncovered through molecular biology and selective conotoxin probes presents an exciting opportunity for the discovery of new therapeutic agents.Read moreRead less
Group A streptococcus (GAS) is a bacteria that causes a wide range of disease in humans. GAS diseases are more common in Australias Indigenous population, and other health and economically disadvantaged groups than more affluent groups. In this study we will evaluate the effectiveness of novel vaccine candidates designed to prevent infection from all strains of GAS.

Summary
Bioaffinity mass spectrometry infrastructure to identify small molecules binding to therapeutic targets. The development of anti-infective therapies is challenging because the underlying biology and biochemistry of pathogen virulence is not yet completely understood. This mass spectrometer facility will be used to identify small molecules suited for development into new therapies for malaria, tuberculosis and HIV.
Development of small molecule primary sulfonamides as new drugs for malaria. Malaria is a major global health threat, causing approximately 800,000 deaths annually. Lives can be saved if patients are treated. The use of current antimalarial drugs is limited by drug resistance, low activity and poor safety. This project investigates the effectiveness of a new class of molecule as a safe drug treatment option to kill malaria parasites.
