Summary
Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. ....Bone is continually being formed and broken down, and these two processes are critical forthe maintenance of a normal skeleton. These processes are dependent upon communication between the bone building and degrading cells, and the hormones growth factors and cytokines that are present in the circulation or produced in bone. The tightly regulated processes of bone formation and degradation need to remain equal, and are essential for the achievement and maintenance of skeletal strength and form. Osteoporosis results from an excess of bone breakdown over formation, and our Program aims to identify the factors that regulate these processes, and develop new therapies that can modify them. We will also determine what it is about bone cell properties that make some cancers, especially those of breast and prostate, particularly prone to spread to bone.Read moreRead less

Summary
The development of normal verbal communication is of the utmost importance to human health. Stuttering is a prevalent disorder that severely interferes with communication.

Stuttering is a prevalent disorder that severely interferes with communication. It can be disfiguring and typically causes speech related social anxiety. Social phobia is present in around half of adults affected. It prevents attainment of occupational potential and children who stutter are typically teased and bullied at school. For the past decade NHMRC Project funding has enabled the present team to conduct world class basic research and clinical trials in stuttering. Significant gains have resulted from that research, in particular the development of treatments across the age groups that have a significant evidence base. However, it is becoming increasingly clear that there are serious barriers to the implementation of these evidence based treatments, and innovative treatment developments are needed to address this. In particular, speech pathology services for rural and remotely located patients and their families are incompletely funded, and even in urban settings workplace restrictions have resulted in speech pathologists delivering incomplete and piecemeal treatments. The program of research will develop the following innovative treatment models to solve this problem: �Distance intervention models for the delivery of speech pathology services to rural patients and their families and others who are isolated from treatment services. �Self-managed treatment models for children and adults who stutter, including procedures to minimise the ubiquitous problem of relapse in adults. It is widely understood that social anxiety is a significant problem for many stutterers and research is urgently needed to establish the extent of social anxiety in stutterers across the age groups and its negative effects on treatment effectiveness. Thus, a further aim of this program of research is to: �Identify those patients for whom social anxiety is likely to constitute a barrier to successful treatment. �Develop supplementary interventions to meet the needs of those socially anxious patients. The cause of stuttering is unknown. Understanding the mechanisms underpinning effective behavioural treatments would contribute to understanding causal factors in stuttering. Thus, this program of research also aims to: �Establish why behavioural treatments work, thereby generating new knowledge about causal factors.Read moreRead less

We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will address the structural and biochemical basis for operation of an immune molecule called tapasin and unravel the basis for how some viruses escape the function of this molecule, thus allowing their immune evasion. We will also explore the use of modified small proteins called peptides in a humanized model of gluten hypersensitivity resembling that of Celiac disease. The molecular basis of the natural human immune system's capacity to recognise and reject grafts will be examined. This complements work aimed at improving the prediction of clinical graft rejection in transplantation. Dendritic cells play a central role in immunity, responsible for capturing material, whether from micro-organisms or self tissues, and presenting it to cells of the immune system. Our program will study the development and immunological function of the different dendritic cell subtypes. We will determine the relative contribution of each to the maintenance of immune tolerance and to the induction of immunity to several pathogens, including herpes simplex virus and malaria. Novel dendritic cell surface molecules that we have discovered will be tested for their ability to enhance the effectiveness of vaccines. Overall, this program utilises a broad array of immunological techniques designed to dissect the development and function of various immune system cell types and determine the structure-function relationships between important cell surface molecules involved in immunity.Read moreRead less

Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully persist within reservoirs in the human body. The research program brings together a group of 6 leading scientists and clinicians located at 3 sites in 2 Australian cities. The team is comprised of experts in the study of HIV-AIDS, cytomegalovirus and herpes simplex virus who will combine their knowledge and expertise to speed up the process of research on these viruses that are of major health importance. Studies will also utilise a number of cutting edge technologies that now make it possible to much more rapidly and precisely determine how viruses cause disease. Advances in our understanding of how viruses persist may form the basis for treatments aimed at controlling persistent infections and the serious diseases caused by these viruses.Read moreRead less

For the foreseeable future, these conditions will remain leading causes of death and disease in Australia and most other countries in the region. While there are many established treatment and prevention strategies for these conditions there remains great potential for further advances to be made, which might avert very large numbers of premature deaths and serious disabling outcomes. This Program of research seeks to provide new information that will give patients, doctors and policy makers innovative options for the treatment and prevention of heart attack and stroke. The Program will incorporate two main elements: observational studies and randomised controlled trials. The observational studies will establish the precise importance of each of the main causes of cardiovascular diseases (such as diabetes, blood pressure, smoking and cholesterol) at different ages, in different ethnic groups and in different geographic regions. Furthermore, these studies will also define the relative importance of established and novel risk factors for cardiovascular disease, providing important new information about how resources for prevention should be directed. The large-scale trials will provide evidence about the effectiveness and safety of a range of new cardiovascular disease prevention and treatment strategies. The work will build on the team�s very successful approach of evaluating the effects of established interventions in high-risk groups for whom those particular treatments are not currently indicated.The Program will also include studies that address the critical issue of translating health research findings into practice _ in terms of health policy, clinical practice and consumer behaviour. A particular focus involves the application and evaluation of novel Internet technologies for promoting best practice. The methodologies used by the team will ensure that the evidence generated by the Program is as precise and reliable as possible, in order to provide a sound base to guide decisions about changes in health care policy and practice. The research findings will have direct relevance to the healthcare needs of millions of Australians within the next five years, and the impact of the work will be assured by the development of implementation and dissemination plans for each major component of the Program.Read moreRead less

Almost two million Australians suffer from the debilitating effects of heart disease and it is the leading cause of premature permanent disability in our workers. Heart defects are also the most common type of birth defect and the leading cause of deaths in infants dying from birth defects. Many of these problems can be attributed directly to defects in the development, repair and-or function of heart muscle and, at the cellular level, of heart muscle cells or cardiomyocytes. Understanding the cardiomyocyte as well as integrated heart development, biology, physiology and function, therefore, holds great promise for major advances in the prevention and treatment of contemporary heart diseases. This Program Grant brings together a unique team of interactive researchers with expertise in cardiovascular physiology, as well as developmental, cellular and molecular biology. The outcomes anticipated from new insights into heart biology that will result from the proposed studies, are the development of novel therapeutic approaches for the prevention and treatment of heart attacks and heart failure.Read moreRead less
