Novel Nanotechnology Strategies For Drug Co-delivery And Combined Therapies In The Brain
Funder

Funding Amount
$1,512,250.00
Summary
Key challenges for treating brain diseases include effective delivery of drugs into the brain and targeted delivery to pathogenic areas. I have developed two world-first drug delivery systems that address these challenges. This project will expand their loading and brain delivery capability to deliver a broad range of novel multiple therapeutics to target sites in the brain. Human brain disease models will be used for systematic preclinical evaluation of novel delivery systems and therapeutics.
A Long-Lasting Oral Drug Delivery System Using Spiky Silica Nanoparticles

Funding Amount
$645,205.00
Summary
This project aims to develop a novel silica nanoparticle-based delivery system for long-lasting oral drug delivery. The particles will be engineered with a spiky morphology that will increase adhesion to the gastrointestinal tract enabling sustained drug release for days or even weeks. Longer lasting oral drug formulations would make it much easier for patients to adhere to the treatment schedules required in chronic diseases like HIV and increase the effectiveness of therapy.
Quantifying And Reducing The Burden Of New And Emerging Psychoactive Substances In Australia
Funder
National Health and Medical Research Council
Funding Amount
$645,205.00
Summary
The public health threat posed by emerging drugs of concern (e.g., new psychoactive substances (NPS) and crystalline methamphetamine) requires timely and effective public health interventions. This research program will strengthen estimates of the global NPS health burden, enhance the surveillance of unwitting drug consumption, and develop and evaluate novel harm reduction responses. Findings will inform policy and health service delivery, both globally and within Australia.
Systems-based Study, Intervention, Diagnosis And Control Of Gastrointestinal Parasites

Funding Amount
$2,538,220.00
Summary
Gastrointestinal parasites cause billions of infections and hundreds of thousand of deaths globally each year. Even in developed countries, these parasites remain an important public health risk, through the cost of their control, the acute impacts of infection and their contribution to post-infectious irritable bowel syndrome and chronic fatigue. My team employs cutting-edge methods to improve their diagnosis, surveillance, treatment and control.
Over the next 5 years my team and I plan to study parasite invasion and blood cell enslavement to guide the design of better vaccines and medicines. Malaria as a deadly parasitic disease caused by large-scale infection of the body’s red blood cells. To design more effective vaccines and improved drugs to globally eliminate malaria we need to improve our understanding of how parasites infect and enslave our blood cells so they can grow rapidly and avoid our immune system.
The role of phosphoinositides in endosomal maturation dynamics. This project aims to investigate the regulation of an intracellular compartment within a cell called endosomes, which plays critical roles in cellular homeostasis, signalling and pathogen entry. New knowledge is expected to be generated in understanding endosome maturation and the signalling events that drive this process using a unique, multidisciplinary approach combining state of the art imaging techniques and high throughput pro ....The role of phosphoinositides in endosomal maturation dynamics. This project aims to investigate the regulation of an intracellular compartment within a cell called endosomes, which plays critical roles in cellular homeostasis, signalling and pathogen entry. New knowledge is expected to be generated in understanding endosome maturation and the signalling events that drive this process using a unique, multidisciplinary approach combining state of the art imaging techniques and high throughput protein analysis. The anticipated outcomes will be to define the molecular steps that govern the membrane-bound machinery on endosomes that directs endosomal maturation. This should provide significant benefits in delineating a process that is linked to almost all aspects of cell life.Read moreRead less
Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pa ....Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pathogen and mitochondrial biology and advanced cell biology tools. With most of the effector proteins yet to be characterised, benefits from the project will be to reveal specifically how these target mitochondria, and more broadly, how bacterial pathogens manipulate organelles for their survival.Read moreRead less
Organising Intracellular Compartments by Formation of Transport Carriers. This project aims to investigate the cellular components which generate carriers that transport material between compartments within the cell. The process of sorting proteins and sending them to the right place is a fundamental mechanism critical to understand how individual proteins function as the move around within cells. The generated knowledge about how cells organise themselves through the movement of proteins betwee ....Organising Intracellular Compartments by Formation of Transport Carriers. This project aims to investigate the cellular components which generate carriers that transport material between compartments within the cell. The process of sorting proteins and sending them to the right place is a fundamental mechanism critical to understand how individual proteins function as the move around within cells. The generated knowledge about how cells organise themselves through the movement of proteins between endosomal intracellular compartments will provide significant benefits by enhancing our capacity to understand this conserved cellular pathway which ensures the integrity of all cellular processes including signalling, communication, homeostasis and development.Read moreRead less

This project investigates how brain cells use their molecular machinery to communicate with one another. At the heart of this process lies the synapses, the contact points that connect brain cells. This project will employ an innovative combination of quantitative microscopy techniques, gene knockout mouse models, and advanced computational and mathematical analyses to generate new knowledge on how a crucial set of proteins organises in space and time to regulate synaptic connectivity. This will provide significant benefits, including molecular-level insight into the inner workings of the brain and interdisciplinary training for students. The expected outcomes include a deeper understanding of brain functions, such as learning and memory.Read moreRead less
