Funding Amount
$527,286.00
Summary
This project aims to generate new, smart polymers for use in re-building muscle that has degenerated due to disease and-or trauma damage. The merger of smart polymers with biologically based solutions and cells has great potential to improve outcomes of treatments of damaged muscle in diseases such as Muscular Dystrophy.
The Role Of Myo18b In Myopathies And Sarcomere Assembly

Summary
Muscle force is provided by a specific structure within the muscle cell termed the sarcomere. Sarcomeres are the engine-room of muscle cells, that act as complex cellular machines to controls muscle contraction. Many muscle degenerative disorders are caused by defects within the sarcomeres, but how this occurs is not well understood. This grant examines how one such muscle waiting disease, or myopathy, results from mutations in a gene encoding a component of the sarcomere called Myo18b.
Effects Of Fast Versus Slow Weight Loss On Fat, Muscle And Bone In Postmenopausal Women

Summary
Very low energy diets (VLED) are increasingly used to treat obesity. Of concern is the fact that VLED induce adaptive responses that can inhibit loss of, and promote regain of, abdominal fat while decreasing lean body mass, muscle strength and bone density. This project will therefore determine whether VLEDs could have negative effects on body composition that increase the risk of metabolic disease, sarcopenia or osteoporosis, and if so, what mechanisms are involved.
The Effects Of Tonic Muscle Pain On The Sympathetic And Somatic Motor Systems In Human Subjects

Funding Amount
$462,948.00
Summary
The main objective of this proposal is to reveal the effects of nociceptive reflexes in humans, and thus identify their functional and clinical implications. By performing invasive recordings from the nerves that control blood vessels and muscles in healthy volunteers subjected to long-lasting (~1 hour) experimental pain, this work will increase our understanding of the adaptive changes that pain induces and improve treatments to prevent pain from becoming chronic.
Reprogramming Macrophage Function In The Elderly To Rescue Impaired Inflammatory Responses To Muscle Injury

Funding Amount
$410,983.00
Summary
Muscle injury in the elderly often takes longer to heal than in younger people, however the cells responsible for this delayed healing are not well understood. Key inflammatory cells required for muscle repair in young hosts are macrophages. However, during aging we have shown that macrophage function is altered, but the mechanism is unknown. This project aims to determine the mechanisms behind age-related changes to macrophages and whether they can be targeted to improve elderly muscle repair.
Novel Insights Into The Mechanisms Of How Viruses Cause Arthritis-arthralgia

Funding Amount
$626,459.00
Summary
Many viruses are known to cause arthritis (e.g. HIV, hepatitis viruses, mosquito borne viruses). Symptoms of viral arthritis include joint pain, stiffness, and swelling. The mechanism of disease is poorly understood. We have developed a novel animal model of disease by which to study arthritic disease caused by viral infections. This model provides an excellent opportunity to explore the mechanisms of rheumatic disease in a complete functioning animal and to explore new treatment regimes.
Exploring The Therapeutic Potential Of TRAIL In Diabetes And The Metabolic Syndrome

Summary
TNF-related apoptosis-inducing ligand (TRAIL) is a protein with potentially useful actions in human health and disease. TRAIL is able to prevent atherosclerosis, the cause of heart attacks and strokes. In addition, we have recently shown that its actions on fat and the pancreas may prevent the development of the metabolic syndrome and type 2 diabetes. These studies will explore the therapeutic potential of TRAIL for the prevention of diabetes and heart disease in a range of animal models.
We have discovered a single tumour factor which causes cancer cachexia, a wasting condition that is one of the worst complications of malignancy, for which there is no current effective treatment. We have developed antibodies which effectively block this condition in preclinical models and have produced human/humanised version of this. This application is to characterise these human antibodies to allow us proceed to clinical trials.
