Acupuncture And Mucosal Immunity In The Upper Respiratory Tract

Summary
Many Australians seek complementary and alternate medicine for the treatment of allergic diseases such as allergic rhinitis. There is evidence that acupuncture treatment is clinically beneficial for the treatment of allergic rhinitis. This project will produce new information that will provide a scientific basis of how acupuncture influences the immune response and modulates inflammation. Broader application to other inflammatory diseases and therapeutic interventions is possible.
Cell Surface Mucins In Gastrointestinal Mucosal Innate Immunity

Summary
Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. We have recently identified three of the seven genes currently known to produce this type of molecule. We propose that mucins have a very important role in maintaining the barrier between potentially infectious microorganisms often present in epithelial tracts and the internal organs. We also believe t ....Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. We have recently identified three of the seven genes currently known to produce this type of molecule. We propose that mucins have a very important role in maintaining the barrier between potentially infectious microorganisms often present in epithelial tracts and the internal organs. We also believe that these molecules trigger epithelial cell defensive responses to the presence of microorganisms. The proposed research aims to prove these propositions and to elucidate the molecular mechanisms underlying function of cell surface mucins. Understanding the function of cell surface mucins could lead to the development of new drugs to treat epithelial inflammation such as that seen in inflammatory bowel diseases and respiratory diseases such as asthma and cystic fibrosis.Read moreRead less
Cell Surface Mucins In Gastrointestinal Infection And Inflammation

Summary
Mucosal tissues, such as the gastrointestinal and respiratory tracts, are the most common site of infectious disease. We have found that the cells in these tissues produce molecules on their surface, known as mucins, that protect from infection. In the case of chronic infection the mucins prevent the inflammation that underlies the development of cancer. In this project we will be exploring the mechanisms by which mucins prevent infection and inflammation.
Enhancement Of Mucosal Immunity And CTL Avidity Against HIV-1

Summary
Production of strong antiviral immunity at the local mucosa (genito-rectal track) is essential for protection against HIV-AIDS. We believe that expression of small hormone-like molecules known as Th2 cytokines IL-4-IL-13 negatively influence the generation of protective immunity against HIV. Thus we aim to counteract these effects by co-expressing proteins known as chemokines together with vaccine antigens to improve the quality of mucosal vaccine immunity.
The Impact Of Influenza A Virus PB1-F2 Protein On Host Immunity And The Potential For Therapeutic Targeting

Summary
The 1918 influenza virus pandemic resulted in 50 million deaths globally and there is potential for new pandemics, such as the predicted H5N1 Bird Flu . Exact causes of such devastating lethality are not fully identified. Newly discovered influenza A virus (IAV) PB1-F2 protein is present in nearly all highly pathogenic IAVs and promotes virus virulence. This study will further examine the way in which PB1-F2 impacts the host, revealing potential therapeutic targets to lessen disease burden.
