Parasite virulence: the role of activation and suppression of P2X7 receptors. Toxoplasmosis and leishmaniasis pose a threat to the health and well-being of the Australian human and animal populations. Around 6-8 million Australians are infected with Toxoplasma, a parasite that can cause severe problems in immunosuppressed individuals and birth defects and miscarriage in pregnant women with a primary infection. Toxoplasmosis is also the main cause of abortion and stillbirth in Australian sheep. L ....Parasite virulence: the role of activation and suppression of P2X7 receptors. Toxoplasmosis and leishmaniasis pose a threat to the health and well-being of the Australian human and animal populations. Around 6-8 million Australians are infected with Toxoplasma, a parasite that can cause severe problems in immunosuppressed individuals and birth defects and miscarriage in pregnant women with a primary infection. Toxoplasmosis is also the main cause of abortion and stillbirth in Australian sheep. Leishmaniasis, recently found in Australia, is a risk for overseas travellers, livestock and wildlife. This research will provide an understanding of what makes these parasites successful, paving the way for development of novel drugs to combat these chronic diseases.Read moreRead less
Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics ....Molecular and antibody analysis of cytomegalovirus (CMV) infection of fetal and placental cells. CMV is a beta herpesvirus with many unknown molecular mechanisms associated with cellular infection. The virus infects placental cells in vivo, although pathogenesis of viral damage to these cells has been extremely difficult to study in vitro. We have commenced a study to i) demonstrate the molecular accompaniments of infection of placental cells in vitro, ii) determine the genotypic characteristics of congenital CMV infections, in collaboration with Abbott Diagnostics, and iii) produce an in vivo model of CMV infection to demonstrate the pathogenesis of cellular injury. The combination of molecular expertise at UNSW with monoclonal antibody expertise from Abbott Diagnostics mean this project is unique worldwide.Read moreRead less
The effect of age on regulatory T cell control of the innate and adaptive antiviral immune responses. Viral pathogens are a lead cause of infant mortality in the world. This project will define how T regulatory cells limit protective antiviral immune responses in the young. This information is critical for the development of potent antiviral vaccines that are effective from the newborn period without inducing autoimmunity. It will also provide novel insight into the way T regulatory cells can b ....The effect of age on regulatory T cell control of the innate and adaptive antiviral immune responses. Viral pathogens are a lead cause of infant mortality in the world. This project will define how T regulatory cells limit protective antiviral immune responses in the young. This information is critical for the development of potent antiviral vaccines that are effective from the newborn period without inducing autoimmunity. It will also provide novel insight into the way T regulatory cells can be manipulated both to dampen immunity, which can be used to develop strategies to reduce immune mediated disease and limit transplant rejection.
