We use a mouse model of inflammatory bowel disease (IBD) to determine how sensations from the inflamed gut are processed in the spinal cord. Over 60,000 Australians suffer from IBD and debilitating pain is a major symptom. Surprisingly, we know very little about how pain signals originating in the normal or the diseased gut are organised and processed in the central nervous system. Obtaining such information is a necessary first step before we can develop therapies to relieve gut pain.
Information Encoding By Temporal Structure Of Afferent Spike Trains

Summary
Our ability to sense, discriminate and interpret touch stimuli underpins some of the most crucial functions of the human hand that relate to object exploration and manipulation. The fundamental mechanism of how nerve impulses generated by tactile receptors are interpreted by the nervous system is not understood. Only by discovering the underlying neural encoding mechanisms can we appreciate the functional impairments in patients and learn to identify them before they become widespread and irreve ....Our ability to sense, discriminate and interpret touch stimuli underpins some of the most crucial functions of the human hand that relate to object exploration and manipulation.

Refining And Testing A Promising New Treatment For Chronic Pain.

Funding Amount
$743,947.00
Summary
Chronic pain costs Australia about 35 billion dollars a year. Recent scientific discoveries show that treatment aimed at correcting problems in how the brain processes sensory input can reduce pain and disability. This project will clarify some key aspects of these problems and use that information to make final adjustments to an already very promising treatment. We will then test the treatment in a definitive and comprehensive clinical trial.
Effective Sensory Rehabilitation After Stroke: Targeting Viable Brain Networks.

Funding Amount
$767,525.00
Summary
New therapies have been developed to help the brain recover after stroke. We will compare brain networks involved in recovery of touch sensation under two new training conditions and in individuals with interruption to different parts of the network. Brain imaging will identify the functional and anatomical connections between brain regions. Our findings will guide therapists in choosing the best therapy for the right individual, based on knowledge of brain networks that have capacity to adapt.
Strategies To Restore Bladder Control After Peripheral Nerve Injury

Funding Amount
$519,967.00
Summary
A major complication of pelvic surgery is loss of bladder control, mainly due to nerve injury at the time of removing cancerous tissue. This has a big effect on quality of life. Very little research has been conducted on injured bladder nerves. In this project we will investigate what happens to bladder nerves after injury and how we can make them regrow. We will also investigate if undamaged bladder nerves can be made to compensate for the lost function.
Pain Systems Analysis Highlights PI3K Gamma As A Candidate Regulator Of Nociception.

Summary
Chronic pain will affect most of us at one point in our life, and there is a need for new drugs to manage this condition. The goal of this project is to use our computer modeling of genetic data from multiple species to predict new drug targets, and then use mouse models to look at the mechanism of action for predicted drug targets, and validate one potential drug target in particular for its therapeutic abilities to stop chronic pain.
Targeting GDNF Family Ligand (GFL) Signalling To Treat Inflammatory Bone Pain

Funding Amount
$329,285.00
Summary
Pain associated with bone marrow oedema syndromes, osteomyelitis, osteoarthritis, fractures and bone cancer causes a major burden on individuals and health care systems in Australia and worldwide. In this application, we will explore specific signalling pathways that we have identified in nerves that code bone pain. This will provide an opportunity for the rational design of highly specific drugs capable of interacting exclusively with molecules that drive pain in these conditions.
Reduction Of Chronic Post-surgical Pain With Ketamine - ROCKet Study

Funding Amount

Summary
Chronic post-surgical pain (CPSP) is a common complication of major surgery, and a significant burden on quality of life and ongoing health costs. Ketamine is a drug used by anaesthetists to treat severe acute surgical pain. Various small studies suggest that it may be unique in its ability to reduce the risk of CPSP. We propose a large trial of ketamine during & after anaesthesia for major surgery to test this. Demonstration of effectiveness would promote widespread change in clinical practice.
Piezo2 And Pain - Is There A Role For Piezo2 In Mechanically Induced Bone Pain?

Funding Amount
$543,848.00
Summary
Pain associated with bone marrow edema, osteoarthritis, bone cancer and fracture puts a significant burden on individuals, society, and the health care system in Australia. A dominant feature of these includes mechanical disturbances of the bone, and this is a trigger for the pain. In this study, we will determine if a newly discovered mechanically gated ion channel (Piezo2) is a key contributor to mechanically induced bone pain and could be a target for development of drugs to treat it.
Testing The Imprecision Hypothesis Of Chronic Pain.

Summary
Pain usually occurs when something triggers activity in danger receptors, which are all over the body. The brain receives a huge amount of other sensory input too, which tells the brain what was happening when the danger arose. The brain imprints this sensory barrage and uses it as an early (painful!) warning system next time. If the imprint is imprecise, then the painful warning occurs in non-dangerous situations. We will test whether imprecise imprinting of the sensory input causes the gradual ....Pain usually occurs when something triggers activity in danger receptors, which are all over the body.

We will test whether imprecise imprinting of the sensory input causes the gradual development of chronic debilitating pain.Read moreRead less
