Summary
The same nerve receptor that binds the pungent component of chilli peppers (TRPV1) is an important part of our pain pathway. TRPV1 also responds to painful heat and acids. Chronic pain is an important unmet medical need and it uses the TRPV1 pathway. After activation by chilli, a feedback system in nerves inactivates TRPV1 and stops pain signalling. This feedback changes in chronic pain. This project aims to understand and exploit this feedback mechanism to find new approaches to pain therapy.

Summary
After nerve or tissue injury including burns, some people will suffer from a condition called neuropathic pain. This is a condition where chronic pain is endured, often totally unrelated to the initial injury or induced by events that would normally not be painful. Our project will determine whether this abnormal pain response is due to an abnormal communication between the nerves that carry pain signals (sensory nerves) and nerves that form part of the sympathetic nervous system, which is part ....After nerve or tissue injury including burns, some people will suffer from a condition called neuropathic pain. This is a condition where chronic pain is endured, often totally unrelated to the initial injury or induced by events that would normally not be painful. Our project will determine whether this abnormal pain response is due to an abnormal communication between the nerves that carry pain signals (sensory nerves) and nerves that form part of the sympathetic nervous system, which is part of autonomic (or involuntary) nervous system. We believe that this abnormal communication is due to an increase in the expression of special receptors called adrenergic receptors, on the sensory nerves. Our project will look at these receptors in the skin of animals that have had pain conditions induced, and also in skin samples from patients who suffer from neuropathic pain that can be classified as sensitive to sympathetic stimulation. By better understanding how neuropathic pain is derived, we can open the door to novel treatment approaches in these difficult to treat conditions.Read moreRead less
NEU-HORIZONS: The Neuroprotection And Therapeutic Use Of Riluzole For The Prevention Of Oxaliplatin Neurotoxicity Study.

Summary
Colorectal cancer is the second most commonly diagnosed cancer in Australia, with more than 13500 cases recorded annually. Oxaliplatin is an effective chemotherapy for the treatment of colorectal cancer. The major side-effect of oxaliplatin is the development of nerve damage that leads to loss of feeling in the hands and feet and significant disability. The aim of this study is to conduct a trial of a new treatment for oxaliplatin-induced nerve damage.
Diabetic neuropathy causes severe disability, with pain, loss of sensation and weakness. The current project will assess the utility of a new testing method, known as nerve excitability assessment, as a method of detecting early changes in nerve function in diabetic patients. If this technique proves useful in detecting early nerve damage, it will assist in the development of therapeutic and preventative treatments for neuropathy in diabetic patients.
Nerve Excitability Assessment: A Novel Biomarker For The Early Detection Of Diabetic Neuropathy.

Summary
Australia has one of the highest rates of diabetes in the world. Diabetes may be complicated by the development of nerve damage, causing weakness and pain in the upper and lower limbs. The cause remains unclear and there are no tools available for its early detection. This study will provide further information about the cause of diabetic neuropathy and will investigate more sophisticated means for its early detection.
Promoting Regrowth Of Nerve Fibres Into The Epidermis During Diabetic Neuropathy By LRP Agonists

Summary
Nerve damage can develop post injury or disease and is often very debilitating, slow to heal and can cause increased pain. Our work aims to examine a new class of molecules that we show can activate selected fat-receptors on nerve cells to guide the growth of regenerating nerves. We will determine how these receptors function with the aim of developing a novel class of therapeutics directed at healing nerve damage.
Enhanced Sensory Perception Via Jitter Reduction And Neural Synchronisation Evoked By Subsensory Electrical Noise Stimulation – Restoring Sensitivity In Peripheral Neuropathy
Funder

Funding Amount
$318,473.00
Summary
The elderly and patients with diabetes are at high risk of losing sensation in their feet and currently no treatment for this condition exists. This loss of feeling leads to falls, fractures and foot ulcers, which in many cases end with amputation. We have developed a new subsensory stimulation technique which for the first time restores lost sensation. Development of this novel treatment is made possible by a multi-disciplinary team of engineers, neuroscientists, physiologists and podiatrists.
How Amyloid Causes Neurodegeneration: The Role Of Transthyretin In Familial Amyloidotic Polyneuropathy

Funding Amount
$618,950.00
Summary
This project seeks to understand the biochemical basis of nerve degeneration in a disease known as familial amyloidotic polyneuropathy. This disease is caused by a protein known as transthyretin, which is abnormally deposited around nerves and causes nerve damage. The project is highly likely to provide clues which help us understand some related dementia causing diseases like Alzheimer's disease and prion diseases such as scrapie and mad cow disease.
