Summary
Pain following injury usually dissipates as the injury heals, however in some individuals it persists and lasts for years. Chronic pain is extremely difficult to treat, particularly that which originates from a damaged nerve. One of the roadblocks in developing effective treatments is our limited understanding of the pathophysiology. The overall aim of this proposal is to address this gap and determine the processes that occur in the brain that results in acute pain transitioning to chronic.
Betacellulin: Defining A Novel Sub-type In Schizophrenia

Funding Amount
$907,515.00
Summary
Schizophrenia is a severe lifelong mental disorder affecting 0.7% of the world population with only partially effective symptomatic treatments. Its cause is unknown and thus cures cannot be developed currently. A promising candidate is betacellulin a growth factor which is very reduced in the brain and blood of people with schizophrenia. Little is known about its role in the brain and this project seeks to identify its relevance to schizophrenia as a step to develop new treatments.
Defining The Genes That Dictate The Cellular Response To Tumour Protein TP53 Activation

Summary
The tumour suppressor TP53 prevents the growth of abnormal cells by activating processes such as cell death and irreversible growth arrest. A cell will undergo only one of these possible responses, but it is not known why some cells die and others only stop growing. We will use innovative methods to define the genes that dictate the cellular response to TP53 activation. This research has implications for cancer, as many therapeutics aim to permanently kill cancer cells by activating TP53.
Understanding Sex Differences In Alcohol Use Disorder: The Role Of Stress And Neuropeptides

Summary
Alcohol use disorders (AUD) are an emerging issue in women, yet there is little understanding of the how the male and female brains differ in response to excessive alcohol consumption. In pilot studies, we have found that deletion of a specific brain chemical causes differences in the way male and female mice consume alcohol in excess. We will further characterise this system and test new approaches to reduce the desire to consume alcohol.
This study aims to elucidate central pathways which can be manipulated to drive the storage of excess energy away from fat and instead directing it into the production of bone mass. Having identified leptin-responsive NPY neurons as important in the control of energy partitioning, we will focus on manipulating these neurons in the hypothalamus using innovative technology to alter body composition. This research has the potential to result in novel treatments for obesity and osteoporosis.
Identifying How The Enteric Nervous System Regulates Gut Permeability In Autism

Summary
This project aims to investigate causes of increased gut permeability in neurological disorders including autism and will apply neuroscience, immunological and microbiology techniques to clarify the causes of increased gut permeability in a well-characterised genetic mouse model of autism.
Harnessing The Dual Roles Of Pericytes To Improve Stroke Outcomes

Funding Amount
$853,943.00
Summary
Pericytes are cells that are in the walls of capillaries - the smallest blood vessels. Pericytes control blood flow and help promote recovery after injury. In stroke, pericytes squeeze the capillary shut, limiting the amount of energy getting to the brain. This proposal will use innovative techniques to understand how pericytes limit blood flow and also how we can utilise pericytes to improve brain recovery after stroke. This will allow us to identify new potential treatment options for stroke.
Development Of An Intracellular Tau-specific Antibody Therapeutic For The Treatment Of Alzheimer's Disease

Funding Amount
$410,378.00
Summary
The protein, tau, is a promising therapeutic target for the treatment of Alzheimer's disease and related dementia's. Targeting tau is a challenge, however, as it is mostly localised within brain cells and a therapeutic must therefore be able to cross multiple barriers to engage and neutralise tau. This project overcomes this hurdle by using virus' to deliver a tau-specific antibody gene across the multiple barriers where it can be produced by brain cells and target intracellular tau.
Integrating Biology And Medicine To Develop 3D-structure Guided Drug Design For Treatment Of Cardiovascular Disease

Funding Amount
$978,832.00
Summary
Calcium channel inhibitors are commonly prescribed for the treatment of heart disorders such as angina, hypertension, arrhythmias and hypertrophic heart disease. This class of drugs is one of the leading causes of drug-related fatalities. The impediment to designing better drugs is a lack of understanding of the 3 dimensional (3D) structure of the calcium channel. We will enable for the first time a 3D structure blueprint for the design of safe and highly selective calcium channel therapeutics.
Characterisation Of Erusiolin - A New Peptide Hormone

Funding Amount
$547,202.00
Summary
Obesity and type II diabetes are epidemic diseases in Australia. Gut-derived hormones are key mediators in these diseases, due to their role in regulating appetite and blood glucose levels. Therapeutic modulation of these hormones also provides significant benefits for patients. In this proposal, we will determine the metabolic functions, such as appetite control, for a previously uncharacterised hormone, which is an unexplored therapeutic target for obesity and diabetes.
