Summary
The prevalence of obesity and its related disorders has reached an alarming level in Australia and other developed countries. Obesity is characterized by the accumulation of fully-differentiated adipocytes loaded with lipid droplets (LDs). We aim to characterize seipin, which regulate both lipid droplet formation and adipocyte differentiation. Results from our proposed studies may offer novel therapeutic strategies against human obesity.
Targeting Dysfunctional Mitochondria In Macrophages To Inhibit Atherosclerosis

Summary
The major contributing cells to heart disease are macrophages. These cells scavenge cholesterol, keeping the blood vessels clean and limiting heart disease. The macrophages must process and donate the scavenged cholesterol onto HDL-cholesterol that carries them back to the liver for removal. This process requires the powerhouse of the cell, the mitochondria to be functional. We have discovered that process fails and have novel drugs to re-instate this process of cholesterol removal.
Molecular Characterization Of SEIPIN Function: Implications For Lipogenesis And Adipogenesis

Summary
Obesity and type II diabetes have become a major health threat to Australians. This project aims to understand how fat is made and stored. Results from this research may lead to novel therapeutic strategies against obesity and diabetes.
Mechanism Of Bacterial Resistance To Antimicrobial Peptides

Summary
Bacterial resistance to antibiotics continues to emerge and intensify. While antimicrobial peptides (AMPs) are a promising alternative to current antibiotics, bacteria have also evolved resistance mechanisms to them through changes in their cell membrane. This application will apply a range of analytical and biophysical tools to understand how bacteria change their cell walls in response to AMPs. The results will allow us to design new combination therapies to treat bacterial infections.

Summary
The world is in a need for effective vaccines for the treatment/prevention of a range of currently occurring diseases. The aim of this project is to develop sugar/lipid-based delivery systems by revolutionary new chemo-enzymatic technology. Expected outcomes of the project will be numerous biologically active vaccine candidates and novel technologies which will lead to effective therapeutic products.
Targeting Lipids Regulated In A Setting Of Physiological Cardiac Hypertrophy

Funding Amount
$489,970.00
Summary
Existing heart failure therapies largely delay heart failure progression rather than reversing the disease. New therapeutic strategies with the ability of improving function of the failing heart are thus greatly needed. The primary goal of this study is to determine whether lipids that are secreted by the heart in a setting of “good” physiological heart growth (as occurs with exercise) can be targeted to restore function of the failing heart.
Targeting A New Regulator Of Cardiac Pathology To Protect The Heart From Cardiac Dysfunction And Arrhythmia

Summary
Heart failure is associated with high mortality, and treatment of this condition represents a major unmet need. We recently reported that specific lipid species are elevated in hearts of mice with heart failure. The goal of this study is to comprehensively examine the therapeutic potential of targeting these lipid species with drugs.
Host Metabolism And Responses Contributing To Flavivirus Replication And Pathogenesis

Summary
We aim to determine how viruses affect the cells they infect, In particular how they can alter the metabolism and balance of lipids in cells and how this impacts the bodies capability to respond immunologically. We believe that by understanding these basic principles we can target ares fr antiviral therapeutic potential.
Understanding How Toxins Interact With Lipid Membranes And Ion Channels

Summary
Chronic pain affects one in five Australians and current treatments have limited effectiveness, with only about one third of patients getting meaningful, pain relief. The aim of the current project is to create alternative treatments for pain that can potentially lead to the reduced suffering and improvement of life quality of many Australians. To achieve this aim we propose to study how spider toxins interact with cells and deactivate sensor targets responsible for chronic pain.

Abnormal subcellular distribution of cholesterol is associated with a number of common diseases including heart disease and Alzheimer’s disease. The overall aim of this proposal is to identify and characterize novel molecules that regulate the transport of intracellular cholesterol. Results from the proposed studies will provide important insights into the molecular mechanisms governing intracellular cholesterol transport and distribution, and will lead to better treatment strategies against hea ....Abnormal subcellular distribution of cholesterol is associated with a number of common diseases including heart disease and Alzheimer’s disease.
