The role of the immune system in pain is emerging from recent discoveries, and may hold the key to novel pain treatments. Most people experience brief gut infections from food or contagion without long-term consequences. Many others suffer symptoms for years afterwards - probably the best example of immune-based pain. Our project investigates how immune cells communicate with sensory nerves, and how these communications change from both angles after gut infection or inflammation.
Non-HFE Haemochromatosis In Australia: Natural History And Molecular Characterisation
Funder

Funding Amount
$179,948.00
Summary
Hereditary haemochromatosis (HH) is a disorder characterised by excessive iron absorption and build up of iron in body organs such as the liver. The excess iron can be toxic and cause disease. Most HH is caused by mutations in the HFE gene. Other forms are caused by mutations in other genes. This project will characterise a new form of HH that is unrelated to any of the previously known genes. The project aims to find the gene for this new condition by genetic analysis in a large family.
Transient Receptor Potential Channels (TRPs) As Transducers And Targets In Primary Visceral Afferents

Summary
Transient receptor potential, or TRP channels, are involved in generating many of the sensations we perceive, such as heat, cold, touch and pain. Some TRP channels are specialized to signal pain from visceral organs, which we must investigate if we are to find treatments for visceral pain, which are currently lacking.
EXAMINING THE RELATIONSHIP BETWEEN MATRIPTASE-2 AND HEMOJUVELIN, TWO ESSENTIAL REGULATORS OF IRON HOMEOSTASIS

Funding Amount

Summary
The control of iron levels is important in health and well being. Too little can lead to iron deficiency and anaemia, conversly too much can lead to haemochromatosis and tissue damage. We will examine the role of two proteins, matriptase-2 and hemojuvelin that when mutated cause iron deficiency or iron overload respectively. We will study how these proteins interact and work in opposite directions to control iron levels. The results will help to develop new therapeutics for iron disorders.
Cognitive Impairments And Post Traumatic Stress Symptoms In Children With Traumatic Brain Injury: A Longitudinal Study

Summary
Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic ....Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic stress, it is not clear how these interact, how they influence long-term outcomes, and what factors such as pre-injury functioning and family support and distress mediate outcomes. These issues are very important since effective rehabilitation of children following traumatic brain injury is essential to maximise long-term functioning and minimise disability. To be effective, rehabilitation must be guided by the knowledge about key factors that determine the recovery process. This study aims to provide answers to these questions by following two cohorts of children (aged 6-14) over 18 months after receiving a traumatic brain injury. In total 240 children will be recruited from Brisbane and Melbourne hospitals. They will be assessed at three, six, twelve and eighteen months post-injury using measures of cognitive, psychological and social functioning. Information on parent distress and behaviours will also be obtained. The information obtained will provide the basis for the development of a specific rehabilitation strategy for children with traumatic brain injury, including information on strategies to help prevent any confounding impact of post-traumatic stress on recovery.Read moreRead less
Molecular Epidemiology Of Melioidosis In Australia

Summary
Melioidosis is an important infection in northern Australia. It is a common cause of fatal pneumonia and blood infection in the region. Two outbreaks of melioidosis with fatalities occurring in remote Aboriginal communities have been linked to contamination of the community water supply with the melioidosis bacteria, Burkholderia pseudomallei. In addition, a rare form of melioidosis affecting the brain and spinal cord has resulted in a number of deaths in healthy Aboriginal people and also a num ....Melioidosis is an important infection in northern Australia. It is a common cause of fatal pneumonia and blood infection in the region. Two outbreaks of melioidosis with fatalities occurring in remote Aboriginal communities have been linked to contamination of the community water supply with the melioidosis bacteria, Burkholderia pseudomallei. In addition, a rare form of melioidosis affecting the brain and spinal cord has resulted in a number of deaths in healthy Aboriginal people and also a number left living in remote communities with severe disabilities such as complete paralysis of both legs. Melioidosis has also been identified in two outbreaks occurring over many years in separate locations in southern Australia. It is thought that it may have been introduced to these regions by imported animals, eg via cattle drives, and human fatalities have occurred after local flooding in these temperate locations. This project is built on the ongoing melioidosis collaboration between researchers in Western Australia, the Northern Territory and Queensland. The aim is to use new DNA fingerprinting methods developed specifically for the melioidosis bacteria to understand better why melioidosis can be such a severe disease and how it spreads from the environment to humans and animals and also how it has possibly spread within Australia and overseas. Better recognition and treatment of melioidosis has resulted in a halving of the death rate from this disease in northern Australia (mortality decreased from 40%-18%). This study aims to give us a better understanding of how this soil and water bacteria interacts with humans to cause such severe disease and will hopefully result in new primary preventative measures to complement the improved diagnosis and treatment.Read moreRead less
20 Year Study Of Skin Cancer In A Queensland Community

Summary
Skin cancers are by far the commonest cancers diagnosed in Australia. Even though it is known that sun exposure in excess causes skin cancers there are complexities about the causes, especially of basal cell carcinoma (BCC) -the major type of skin cancer- that are still not understood. Relative intensity of sun exposure and perhaps its timing with respect to age in life may well be critical factors. We aim to study these causes in very great detail by collating information that has been gathered ....Skin cancers are by far the commonest cancers diagnosed in Australia. Even though it is known that sun exposure in excess causes skin cancers there are complexities about the causes, especially of basal cell carcinoma (BCC) -the major type of skin cancer- that are still not understood. Relative intensity of sun exposure and perhaps its timing with respect to age in life may well be critical factors. We aim to study these causes in very great detail by collating information that has been gathered over a 20 year period in a community-based skin cancer study in Nambour, Qld as well as performing some laboratory tests on skin cancer tissue collected from participants. This 3-year project will enable the full realisation of the potential of this esource-20 years in the making- with its wealth of information for answering questions about skin cancer decelopment and preventability. It should finally provide us with a clearer rationale for 'prevention of skin cancer' than is currently available. In addition we shall assess the costs of treatment of skin cancer in general and for the individual, and how much preventive practices for skin cancer might save the health budget, by using the releavnt data collected from this community sample.Read moreRead less
