Mechanistic and comparative toxicity of commercial essential oils

This project will focus on the investigation of endocrine disruption of male reproductive performance by essential oils in experimental animals. The project will start with a literature review on essential oil endocrine disruption, fertility in the male rat, and differences in their reproductive physiology in comparison to other experimental animals and humans. After that, an experimental program will be developed to identify which physiological pathways are disrupted in experimental animals by oregano oil, and other essential oils of similar or overlapping composition

BSc (Hons) or Masters in Biomedical Science, Toxicology or Pharmacology. The student should be able to demonstrate a strong proficiency of the English language and the ability to take the initiative in the project.

Circuit, Cellular and Synaptic Mechanisms of Nucleus Accumbens Deep Brain Stimulation

The nucleus accumbens (NAc) is a common deep brain stimulation (DBS) target used to treat a diverse range of psychiatric disorders, including obsessive compulsive disorder, addiction, depression, Tourette’s syndrome, and chronic pain. Why the NAc is an effective target across diverse treatment-refractory disorders is not clear. The NAc is rich in dopamine terminals, and dopamine signalling in this region plays an important role in the integration of stress- and reward-related information to regulate the expression of incentive-motivation behaviours. As part of this, NAc dopamine serves as a neuromodulator, effectively gating information flow from cortical and limbic inputs to determine which successfully activates post-synaptic outputs. The location and function of the NAc mean that NAc dopamine is strategically positioned to modulate overall mesocorticolimbic network function. Despite its clinical potential, the effects of NAc DBS on NAc dopamine neurotransmission have not yet been systematically explored. The proposed study is designed to test the central hypothesis that NAc DBS disinhibits midbrain dopamine cells to increase dopamine neurotransmission, and that this is necessary for its behavioural effects. Specifically, we will demonstrate NAc DBS increases phasic NAc dopamine, stress coping and motivated behaviour. We will then identify the cell and receptor mechanisms mediating NAc DBS effects on NAc dopamine and demonstrate that facilitation of NAc dopamine neurotransmission is essential for the behavioural effects of NAc DBS. This investigation will establish the direct effects of NAc DBS on NAc dopamine and NAc dopamine-dependent behaviour, providing an essential foundation for future studies aimed at target optimisation and development of closed-loop feedback technologies.

Monitoring inflammation through quantitation of redox-mediated macrophage polarisation

 

Failure to turn off the body’s immune response results in chronic inflammation characterised by oxidative stress. Such oxidative stress is associated with irreversible cell/tissue damage and linked to a variety of diseases, such as inflammatory arthritis, liver inflammation, and cardiovascular diseases. Therefore, quantitation of these redox biomolecules in macrophages is critical to understand the correlation between redox levels, macrophage polarisation status and inflammation progression.

This project aims to develop and pre-clinically validate advanced responsive probing technology to quantify redox biomolecules produced in macrophages. This research will address major knowledge gaps relating the redox levels with the macrophage polarisation. This information will underpin a novel method for improved diagnosis and monitoring of inflammatory diseases.

Statistical methods for risk prediction of common diseases

Polygenic risk predictors based on a large number of genetic variants can identify a subgroup of individuals at high risk of developing a common disease, such as coronary artery disease, type 2 diabetes, or breast cancer. This risk stratification will greatly facilitate precision medicine through opportunities for early disease diagnosis, prevention and intervention. The overall aim of this project is to develop and implement optimised statistical methods and software to best predict an individual’s disease risk through the use of genetic and non-genetic data. Data available for the analysis include large-scale genetic data from genome-wide association studies, whole-genome sequence data, molecular quantitative phenotypes across tissues and cell types, functional annotations on genomic regions, and longitudinal health conditions and lifestyle phenotypes from biobanks.

Conversational speech in ageing and dementia

The production of propositional language is uniquely human; it is central for communication. Propositional language is voluntary, spontaneous, novel to a context, and distinct from core spoken language skills (e.g., reading, naming, repeating). Prior to producing propositional language, the speaker must generate an idea or message for expression. This preverbal stage of message formulation represents the interface between broader cognition and language. The number of ideas contained in speech, or propositional density, has been suggested to be predictive of dementia later in life; however, evidence is sparse and largely observational.

There are few experimental studies addressing the relationship between cognition and critical mechanisms involved in spoken language and it therefore remains poorly understood. This project will investigate the mechanisms crucial for message formulation and producing propositional language in healthy and pathological ageing populations (e.g., Alzheimer’s disease, frontotemporal dementia, parkinsonian disorders) in order to identify early indicators of decline that can be useful diagnostic markers.

The successful applicant will enrol through the School of Psychology.

Bachelor of psychological science or a Bachelor degree with a psychology major and honours is desirable or a student with a speech and language degree and strong statistical knowledge.

MEASuRES: Driving quality improvement through Meaningful Evaluation of Aphasia SeRvicES

One scholarship is available for either of the following two topics:

1. MEASuRES: Driving quality improvement through Meaningful Evaluation of Aphasia SeRvicES

Despite the existence of a strong evidence-base for aphasia rehabilitation, people with post-stroke aphasia experience poor outcomes. Living with aphasia often means living with lifelong disability associated with social isolation, reduced employment, and an increased risk of depression. The translation of existing evidence to practice has the potential to improve outcomes for this population, however in Australia, there is no systematic means of determining whether the care provided by aphasia services is effective or meets consumer expectations. This project will use consensus methods to establish a minimum data set and core outcome measures for Australian aphasia services. The core set will be piloted in a prospective observational study to assess data quality and feasibility. This body of research represents the first steps in a broader plan to use routine data collection and data linkage to identify and address evidence-practice gaps in aphasia services. 

2. Development of a Measure of Processes of Care (MPOC) for aphasia rehabilitation services.

In addition to clinical measures of process and outcomes, the assessment of health service quality should incorporate the patient perspective. The patient experience is increasingly recognised as a pivotal aspect of health service evaluation. This project will use experience-based co-design methods to develop a patient-reported measure of processes of care (MPOC) in collaboration with people living with aphasia and clinicians who provide aphasia services.

The successful student will enrol through the School of Health & Rehabilitation Sciences. 

This project would suit a candidate with a background in speech pathology / speech therapy.

The role of ion channels in pain pathways

Pain is Australia’s third most costly health problem and has been suggested as the developed world’s largest undiscovered health priority, with health expenditure on persistent pain exceeding that of cancer, diabetes, and stroke. The enormous
socioeconomic cost of poorly relieved chronic pain provides a powerful rationale to increase our understanding of the underlying pathophysiology of pain. In recent years, ion channels have received attention as putative analgesic targets due to their crucial role in neuronal excitability, signal transduction and action potential propagation. However, the precise role of specific ion channel isoforms in modality- and disease-specific pain pathways remains unclear. The aim of this project is to systematically define the functional role(s) and therapeutic potential of ion channel isoforms expressed in sensory neurons using pharmacological, electrophysiological and behavioural approaches.

Structural studies of the mechanism of formation of caveolae

Caveolae are plasma membrane invaginations involved in transport, signalling and mechanical membrane sensing in metazoans. The Cavin proteins are absolutely required for the formation of caveolae, and mutations in cavin proteins (and other caveola-coat proteins) lead to human disorders including lipodystrophy and muscular dystrophy. Alterations in cavin protein expression are also implicated in cancer progression due to perturbed cellular signalling. The fundamental mechanisms by which Cavins regulate caveola formation are still largely unknown and this project will provide important new insights into the role of strictly conserved cavin domains in cavin protein functions. The project will involve the use of structural and biophysical methods such as X-ray crystallography, cryoEM and liposome binding assays to analyse cavin structure and function.

Structural studies of endosomal membrane trafficking

Endosomal trafficking involves the assembly of large dynamic protein complexes, and their interactions with cargo receptors and membrane lipids to generate tubulovesicular carriers. One of the major endosomal trafficking assemblies is the “retromer complex”. This forms membrane tubules that incorporate a host of different cargo molecules and is essential for normal cellular protein and membrane homeostasis. In humans, mutations of the retromer complex are involved in both Parkinson’s disease and Alzheimer’s. The Collins lab has recently reported the crystallographic and cryoEM structures of the retromer complex and associated sorting nexin proteins from yeast, and this PhD project will explore the structure and function of the human retromer and sorting nexin proteins, using approaches including X-ray crystallography, cryo electron microscopy and protein-protein interaction studies. Ultimately the goal is to derive a more complete understanding of the molecular mechanisms that control their function in receptor transport and signalling.

Structure of pathogenic flaviviruses by cryo-EM

Advances in cryo-electron microscopy (cryo-EM) make it now possible to solve the 3D structure of a virus particle within the timeframe of an outbreak, offering the potential to rapidly develop new vaccines and therapies against emerging viral pathogens. The major limits to structural determination now lie in virus isolation, safe lab handling and propagation. This project will overcome these issues using a new chimeric flavivirus technology that allows the production of virus particles that resemble the pathogenic viruses from which they were constructed, but are safe for human handling. This project will use this platform to reveal the structure of several unsolved and highly pathogenic flaviviruses by cryo-EM, providing a rational basis for the development of viral countermeasures.

Developing an effective vaccine against Group A Streptococcus

Globally Australian Aboriginal and Torres Strait Islanders have the highest recorded rate of Group A Streptococcus (GAS) infection, mainly rheumatic heart disease and rheumatic fever. GAS infection is endemic and often fatal due to post-infection problems. This project aims to develop a glycoconjugate vaccine to prevent GAS infection. We aim to avert these deaths by making a vaccine from small, specific parts of GAS proteins so the body makes safe antibodies that stop GAS and its related diseases.

Gain from pain: new tools from venomous animals for exploring pain pathways

Many venomous animals use their venom defensively and envenomation is frequently associated with rapid and often excruciating pain. In most cases the molecular mechanisms by which they achieve this is unknown. A diverse array of biochemical, pharmacological and biophysical techniques will be used to explore animal venoms for new pain-causing toxins, to determine their structure and mechanism of action. This project is likely to uncover toxins that employ new mechanisms of pain signalling, leading to new insights into pain physiology.

Students will enrol through the Institute for Molecular Bioscience.

Development of a first-in-class neuroprotective drug for protecting the brain after stroke

We have developed a peptide drug (Hi1a) that prevents stroke-induced brain damage. Hi1a is the most potent known inhibitor of acid-sensing ion channel 1a (ASIC1a), which is robustly activated during stroke-induced cerebral acidosis. Inhibition of ASIC1a by Hi1a prevents the neuronal death caused by ASIC1a activation. We plan to conduct preclinical safety and efficacy studies with Hi1a to develop a data package for supporting its registration as an Investigational New Drug (IND). We will optimise the dose and mode of administration of Hi1a, determine its optimal and maximal therapeutic time window, and examine its performance across a range of ischemic and haemorrhagic stroke models.

Development of new peptide based delivery system for GAS vaccine

Vaccines are the most effective intervention against infectious diseases. Classical whole organism based vaccination is not always effective and safe, while subunit-based vaccines are poorly immunogenic and need help of an adjuvant. However, many adjuvants are not effective immune stimulators or too toxic for human use.

Therefore, the aim for this project is to develop a novel delivery system with self-adjuvanting properties using unique peptide sequences which are able to self-assemble into nanoparticles. To examine the efficacy of this delivery system, the one or more peptide epitopes from group A streptococcal (GAS) M-protein will be conjugated to the synthesized delivery system to form a peptide-based subunit vaccine. The resulted constructs will be self-assembled to form nanoparticles as well as be incorporated into liposomes. These nanoparticles and liposomes will be examined towards their stability, toxicity, and ability to be recognized by antigen presenting cells in vitro. The most promising candidates will be evaluated in vivo for ability to induce humoral immune responses against GAS. Following initial screening of delivery systems second generation of self-assembled peptides will be generated and examined as vaccine delivery systems. Finally, challenge and opsonization experiments will be performed to determine the most effective delivery system.

The successful applicant will enrol through the School of Chemistry and Molecular Biosciences.

Applicants must hold a 1st Class Honours degree for Masters degree (or equivalet in medicinal chemistry or related fields.

Development of new adjuvants and vaccine delivery systems

Vaccine is highly efficient medical intervention to prevent infectious diseases and reduce related morbidity and mortality worldwide.  Peptide vaccine are able to induce very specific and safe immune responses; however, the need to be administered with strong adjuvants. Adjuvants such as Lipid A are very efficient to stimulated humoral immunity against co-administered antigen. The same time Lipid A is very toxic. To overcome this issue, new analogues of lipid A are proposed here. Lipid A toxicity will be reduced by elimination of phosphate group from its structure and by replacement of lipidic moieties with special self-assembling peptides (similar to transmembrane fragments of proteins). Several derivatives will be synthesized and examined in vitro and in vivo towards inducing immune responses. Leading derivatives will be also examined as part of self-adjuvanting liposomal delivery system (anchoring to membrane in similar way as transmembrane fragment of protein). The sytem will be used to make new vaccine against Goup A Streptococcus.

Using Statistical Techniques in Genetic Epidemiology to Investigate the Developmental Origins of Health and Disease (DOHaD)

There is a well-documented observational relationship between low birthweight infants and increased risk of disease in later life (e.g. type 2 diabetes, hypertension, cardiovascular disease, and many more). This inverse association was initially interpreted as resulting from developmental compensations to an adverse intrauterine environment, which in turn led to long-term changes to offspring physiology and increased susceptibility to disease. This theory was christened the “Developmental Origins of Health and Disease” (DOHaD) and has been one of the preeminent paradigms in life-course epidemiology over the last thirty years. The aim of this project is to investigate the DOHaD hypothesis using a variety of statistical techniques including genome-wide association, Mendelian randomization and G-REML approaches in large scale datasets such as the UK Biobank Study.

HLA-G/H2-Bl is Critical for Regulating Inflammation in the Liver

The key factor to induction of liver fibrosis, progression to cirrhosis, and hepatocellular carcinoma is inflammation. Liver transplant and liver regeneration following liver resection are also dramatically impaired by elevation of inflammation. We have identified a potent anti-inflammatory protein, HLA-G, that is critical for regulating post-surgical inflammation in the liver. We will determine if HLA-G can reverse and/or block liver fibrosis and modify HLA-G for improved clinical potential.
