Summary
Children and adults feel the symptoms of asthma because their airways close up too easily. We have discovered a new mechanism that the healthy lung uses to keep airways open. The epithelial cells which line the airway release an enzyme that cuts of a small part of another protein, called a PAR receptor, that sits on the same cell. When this happens the epithelial cell releases relaxing substances from their lower surface. The relaxing substances keep the airways open.

We have discovered a new mechanism that the healthy lung uses to keep airways open. The epithelial cells which line the airway release an enzyme that cuts of a small part of another protein, called a PAR receptor, that sits on the same cell. When this happens the epithelial cell releases relaxing substances from their lower surface. The relaxing substances keep the airways open. This grant application is designed to test whether the relaxing system also stops the airways from developing inflammation. If the relaxing system does this we will be able to use the knowlege we have that lets us activate the PAR receptors artificially to design new types of drugs. These drugs would be better than existing asthma drugs because they would prevent inflammation and relax the airways at the same time. These drugs could also be useful in other lung diseases such as chronic bronchitis.Read moreRead less
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

Funding Amount
$33,626.00
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.

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. 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 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
