A novel drug class for the effective treatment of Giardia infections. Companion animals play a pivotal role in the lifestyle of the average Australian family. The 9 million cats and dogs, residing in >65% of our households, have provided significant health and well-being benefits to owners, especially during COVID. Ensuring pet health is a primary obligation of pet ownership.

Companion animals play a pivotal role in the lifestyle of the average Australian family. The 9 million cats and dogs, residing in >65% of our households, have provided significant health and well-being benefits to owners, especially during COVID. Ensuring pet health is a primary obligation of pet ownership. Giardia infections (Giardia duodenalis, with 94% of infections in dogs identified as Assemblage A) is the most prevalent enteric parasite identified globally in dogs. Infection rates can be as high as 75% in puppies. Current treatments are failing due to poor efficacy, resistance and poor adherence to treatment schedules. We have identified a novel, extremely rapid acting series of compounds capable of single shot eradication of Giardia.Read moreRead less
Novel peptide mimics for the disruption of chemical communication in bacteria. It is now well established that bacteria communicate with each other via small diffusible signalling molecules and coordinate their activities such as biofilm formation, swarming and expression of virulence factors in a coordinated manner. This project will investigate the synthesis of novel organic molecules that have the capacity to disrupt chemical communication in bacteria. This could allow control of the unwante ....Novel peptide mimics for the disruption of chemical communication in bacteria. It is now well established that bacteria communicate with each other via small diffusible signalling molecules and coordinate their activities such as biofilm formation, swarming and expression of virulence factors in a coordinated manner. This project will investigate the synthesis of novel organic molecules that have the capacity to disrupt chemical communication in bacteria. This could allow control of the unwanted microbial activity without the use of growth inhibitory agents such as antibiotics, preservatives and disinfectants that select for the resistant organisms. This elegant approach to eradicating the virulence behaviour of microbes represents a novel strategy to combat antimicrobial resistance.Read moreRead less

Investigations into the antibacterial mechanism of action of cannabidiol. This project aims to understand how the compound cannabidiol is able to kill bacteria by examining its interactions with bacteria from a genetic and molecular level. This research is critical, because future development of cannabidiol and design of improved analogs is predicated on knowing how it works. Expected outcomes include the first detailed understanding of how cannabidiol interacts with bacteria. This should lead ....Investigations into the antibacterial mechanism of action of cannabidiol.

Scaling in biology: size control at the cell, organelle and organism level. This project aims to decipher the universal mechanisms that coordinate growth with division and thereby dictate the size of the cell. It would investigate this question from the triangulating perspective of evolution using yeast and animal models.

This project aims to decipher the universal mechanisms that coordinate growth with division and thereby dictate the size of the cell. It would investigate this question from the triangulating perspective of evolution using yeast and animal models. It plans to interrogate the complex sub-networks that govern cell size using novel genome-scale reagent sets for systematic genetics and other approaches. It would integrate this data in predictive mathematical models of size control that illuminate how the cell processes size-related information, and how size mechanisms evolve to impact form and function in biology. This research is expected to have commercial applications in biotechnology processes and bioengineering.Read moreRead less
Atomic details of antimicrobial peptides at work in live cells. This project aims to develop methods to determine the detailed structure of biologically important molecules in live cells to better understand how biomolecular structure is related to disease. The structure at the atomic level of the molecules of life is usually characterised by crystal or solution studies in model systems. However, the structure of many biologically important molecules depends on their environment. Using new instr ....Atomic details of antimicrobial peptides at work in live cells. This project aims to develop methods to determine the detailed structure of biologically important molecules in live cells to better understand how biomolecular structure is related to disease. The structure at the atomic level of the molecules of life is usually characterised by crystal or solution studies in model systems. However, the structure of many biologically important molecules depends on their environment. Using new instrumentation and labelling schemes, the project plans to use nuclear magnetic resonance methods to study antibiotics and antimicrobial peptides in live bacteria and human cells. The goal is to resolve how these molecules cross cell membranes and how biomolecular structure is related to activity, which may advance development in biotechnology and therapeutic treatments against drug-resistant infections.Read moreRead less
Poly(amino acids) as immune stimulators. This project aims to develop nanoparticles built from natural hydrophobic amino acids as an immune stimulatory delivery system for peptide antigens. Currently available immune stimulants (adjuvants) are often toxic and/or are poorly chemically defined fragments of bacteria or toxins and vary from batch-to-batch. New adjuvants are in high demand; especially to facilitate the use of optimal, but weakly immunogenic, peptide antigens. It is expected that the ....Poly(amino acids) as immune stimulators. This project aims to develop nanoparticles built from natural hydrophobic amino acids as an immune stimulatory delivery system for peptide antigens. Currently available immune stimulants (adjuvants) are often toxic and/or are poorly chemically defined fragments of bacteria or toxins and vary from batch-to-batch. New adjuvants are in high demand; especially to facilitate the use of optimal, but weakly immunogenic, peptide antigens. It is expected that the proposed project will develop a novel efficient, safe and notably biodegradable self-adjuvanting delivery system that can be fully customised to match an antigen of choice. This foundational research should provide important advances for commercial immune stimulatory applications.Read moreRead less

Electrophysiology Platform for Ion-channel Characterisation. Ion channels are ubiquitous pore-forming membrane proteins, with the human genome encoding >300 ion channels. The diverse roles of ion channels include action potential generation, control of ion flow across secretory and epithelial cells, and regulation of cell volume, motility and proliferation. Pharmacological modulators are powerful tools for probing ion channel function, but for most channels these tools are lacking. Thus, this project aims to develop the first comprehensive toolbox of ion channel modulators using an integrated in vitro/in vivo electrophysiology platform. These pharmacological tools will be made freely available to the Australian research community for probing the mechanism and physiological function of ion channels.Read moreRead less
