Summary
Hearts respond to stimulation by activation of cell surface receptors. We have found that two very closely related receptors have opposing effects on the heart; one is beneficial and the other promotes disease. The planned studies will investigate exactly what explains this difference. This will identify critical factors that protect or damage the heart and is expected to provide suitable targets for drug development.

Alcohol dependence is a major cause of mental and physical illness in Australia. Current medications for treating this condition are of limited effectiveness. This project will investigate the ability of the hormone oxytocin to reduce alcohol abuse and alcohol craving and to reverse the brain damage that alcohol causes. The project will also develop new medications, based on oxytocin, but with more powerful and longer lasting effects.

Summary
Chronic inflammatory lung diseases like asthma and smokers lung are treated with combinations of anti-inflammatory drugs. Powerful anti-inflammatory types of steroid drugs are used in more severe disease. Even these powerful drugs are sometimes not effective enough. Our work is developing an understanding of how inflammation limits the anti-inflammatory effects of steroids and we are devising ways to overcome this with new drugs.

Summary
Chronic pain is a growing and poorly treated global health burden. There is a great need for novel pain therapeutics. We are discovering novel drug targets in pain pathways in the nervous system and new therapeutic molecules that selectively block information flow in pain nerves. Strong pain relieving drugs like morphine also lose their effectiveness after long periods of use. We are finding mechanisms responsible for this thereby providing a rational basis for development of better opioids and ....Chronic pain is a growing and poorly treated global health burden.

The Search For Novel Therapeutic Targets For The Treatment Of Chronic Pain.

Summary
Chronic pain is very common, with one in five Australians suffering long-term pain that is serious enough to cause disability. It is extraordinarily difficult to treat. Medicines used to treat normal pain symptoms are usually ineffective on chronic pain patients because the cause of the pain is different. The aim of this project is to identify new drug targets in the spinal cord that are specific for chronic pain so we can develop new medicines to reverse the symptoms safely and effectively.
Viral Infection And Transforming Growth Factor-beta Impair Glucocorticoid Activity In Epithelial Cells

Summary
Anti-inflammatory types of steroid drugs are commonly used in chronic lung disease including asthma and chronic obstructive pulmonary disease. However, a significant number of sufferers show resistance to the steroid therapy. Our study is developing an understanding of how inflammation limits the anti-inflammatory effects of steroids and we are identifying novel therapeutic targets to improve the effectiveness of treatment of chronic disease.
This proposal utilises forefront technologies to identify and characterise fundamental biological processes influenced by toxic free radicals that are triggered by viruses such as the flu and HIV. The approach is a synergistic collaboration between researchers with unique and complementary expertise across disciplines and across Australian and Irish universities to ultimately identify future drugs to treat viral disease.
Airway Smooth Muscle And Fixed Airway Obstruction: Strategies For Softening Muscle

Summary
In severe asthma the airways don't relax fully making breathing more difficult. The inability to relax is being addressed by exploring the behaviour of isolated muscle cells. These cells are able to compact collagen gels. The mechanisms used to compact the gel are different to those that cause rapid muscular contraction. We aim to identify the molecules responsible for the gel compaction as a first step to identifying new drugs to treat the fixed airway obstruction in severe asthma.
Endocannabinoid-TRP Interactions In Midbrain Analgesic Pathways

Summary
Current pharmacotherapies for chronic pain are often ineffective. The active ingredient of the plant Cannabis sativa, THC, and a number of synthetic cannabinoids have efficacy in these pain states, however, they also produce a spectrum of adverse side-effects. This project will use cellular and behavioural techniques to examine how this cannabinoid system modulates intrinsic pain systems within the midbrain in order provide leads for novel analgesic pharmacotherapies with enhanced efficacy.
Targeting TRPV4 Activation Mechanisms To Reveal Novel Pain Therapies

Funding Amount
$580,938.00
Summary
Pain nerves sense painful chemical and physical stimuli, by opening protein "ion channels" which let small electric currents traverse the cell membrane. This pain signal is transmitted to the spinal cord and then the brain, where it is perceived as pain and elicits a reaction. But we don't know how the ion channels open. This project will investigate how receptors for painful substances open ion channels to cause pain. Understanding this mechanism will help us to make new drugs to treat pain.
