Summary
There are many medical situations where immune suppression is required. Available methods lack specificity and risk infection, drug-related side-effects and cancer. We have discovered a novel way of suppressing immunity such that only unwanted responses are eliminated. This involves virus-mediated delivery of antigen fused to CTLA4-Ig. We plan to test this strategy in the context of gene therapy, to work out how it works and to optimise the approach. Success will have broad health implications.
The aim of this project is to develop mathematical models and computer software capable of predicting immune responses to infection and disease. This “artificial immune system” should lead to improved vaccine design and better understanding of what causes the immune system to attack its own body, causing autoimmune disease, or fail to respond, causing immunodeficiency. This enabling science could then lead to improvements in treatment for a range of conditions of clinical importance.
Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
Development Of Novel Vaccine Strategies To Prevent Genital Tract Chlamydial Infections

Summary
Chlamydia trachomatis is one of the most common sexually transmitted diseases in the developed world. Because an infection can remain undetected it can cause severe long term problems such as infertility. The aim of this project is to develop a successful vaccine using novel immunization regimes that not only protects from infection but also prevents the development of any long term problems.
The Role Of The Dendritic Cell Surface Molecule Clec9A In Dendritic Cell Subset Function And Dead Cell Recognition

Summary
Dendritic cells (DC) are sentinels of the immune system. DC monitor the environment and regulate tolerance to self versus immunity to dangerous material. Different types of DC perform different jobs. We have identified a new surface molecule, Clec9A, on some mouse and human DC. We will investigate the function of Clec9A in the immune response. We will also use Clec9A to help unite mouse and human DC biology, since until now there have been few useful marker molecules common to both species.
Investigating The Potential Effect Of A Novel Immune Regulator (JET) In Preventing Graft Versus Host Disease

Funding Amount

Summary
Graft Versus Host Disease (GVHD) is the primary complication of bone marrow transplants, in which the donor T-cells react with the recipient’s cells causing organ damage. Current treatments are not specific and cause further health problems. This research aims to test the therapeutic potential of a newly discovered molecule (JET) in treating and preventing GVHD. If successful, JET has the potential for treating other conditions such as rheumatoid arthritis, multiple sclerosis and miscarriages.

Summary
One million children die every year of pneumococcal (Pnc) disease, the majority in the third world. Many die in early infancy and babies may benefit from immunisation with a Pnc conjugate vaccine (PrevenarTM) at birth. The Papua New Guinea (PNG) Insatiate of Medical Research; Telethon Institute for Child Health Research and the Department of Paediatrics, University of Western Australia, will collaborate to closely examine the safety of this approach, particularly with regard to impact on the dev ....One million children die every year of pneumococcal (Pnc) disease, the majority in the third world.

The Papua New Guinea (PNG) Insatiate of Medical Research; Telethon Institute for Child Health Research and the Department of Paediatrics, University of Western Australia, will collaborate to closely examine the safety of this approach, particularly with regard to impact on the development of immunity and response to other vaccines given to infants. This study will also provide a unique opportunity for training of PNG and Australian scientists in both countries; transfer state-of-the-art immunological technology and stimulate further collaborations on respiratory infections in the region.Read moreRead less
