Archaeal vesicles: new insights into viral evolution and DNA transfer. This project aims to determine the basis for plasmid and membrane vesicle generation and DNA transfer at the cellular and molecular level. Recent discovery of plasmid vesicles, which transfer plasmid DNA between host cells using viral capsid-like membrane vesicles, suggests they may be an evolutionary precursor for virus particles. The expected project outcomes include the first substantive characterisation of membrane vesicl ....Archaeal vesicles: new insights into viral evolution and DNA transfer. This project aims to determine the basis for plasmid and membrane vesicle generation and DNA transfer at the cellular and molecular level. Recent discovery of plasmid vesicles, which transfer plasmid DNA between host cells using viral capsid-like membrane vesicles, suggests they may be an evolutionary precursor for virus particles. The expected project outcomes include the first substantive characterisation of membrane vesicles in the phylum Euryarchaeota, how plasmid vesicles are generated and transmitted, and new insights into how viruses may evolve. This may lead to new avenues for preventing viral transmission and supporting development of new and improved applications biotechnology and the safe delivery of vaccines or genes in animals and humans.Read moreRead less

Development of SELEX technology (Systematic Evolution of Ligands by EXponential enrichment). A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity. The strategy know as SELEX (Systematic Evolution of Ligands by EXponential enrichment) uses protein biochemistry and PCR technology, with subsequent repeated rounds of selection and amplification, to screen vast libraries of oligonucle ....Development of SELEX technology (Systematic Evolution of Ligands by EXponential enrichment). A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity. The strategy know as SELEX (Systematic Evolution of Ligands by EXponential enrichment) uses protein biochemistry and PCR technology, with subsequent repeated rounds of selection and amplification, to screen vast libraries of oligonucleotides (RNA or DNA) for their ability to bind target proteins. This procedure will be developed by UNSW in collaboration with the biotech company BTF Plc., Ltd., to be used in two applications. The first is the research interest of UNSW and involves the development of aptamers against hepatitis C virus. The second lies within the interests of BTF and will involve the development of aptamers against the water borne pathogen Cryptosporidium parvum.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
A New Platform for Developing a Compound Against Herpes Simplex Virus. This project aims to further explore the research team’s recent fundamental discovery of a protein found naturally in an Australian abalone that inhibits viral entry by blocking three key viral glycoproteins. We would aim to utilise this knowledge towards development of a new class of therapeutics against Herpes simplex viruses (HSV) and their consequent infections.

This project aims to further explore the research team’s recent fundamental discovery of a protein found naturally in an Australian abalone that inhibits viral entry by blocking three key viral glycoproteins. We would aim to utilise this knowledge towards development of a new class of therapeutics against Herpes simplex viruses (HSV) and their consequent infections. The new therapeutics could overcome the low bioavailability of current drugs and thus significantly shorten the recurrence period. Such new drugs may have broad applicability.Read moreRead less
Anthocyanin Inhibitors to the Influenza Virus. The increasing resistance of circulating influenza strains to current anti-viral inhibitors has prompted an investigation to screen, design, synthesize and evaluate a new class of natural product based inhibitors to the virus employing novel and innovative mass spectrometry, computational and structural approaches. Preliminary studies reveal they offer benefits in terms of a different mode of binding to influenza neuraminidase, remote from many know ....Anthocyanin Inhibitors to the Influenza Virus. The increasing resistance of circulating influenza strains to current anti-viral inhibitors has prompted an investigation to screen, design, synthesize and evaluate a new class of natural product based inhibitors to the virus employing novel and innovative mass spectrometry, computational and structural approaches. Preliminary studies reveal they offer benefits in terms of a different mode of binding to influenza neuraminidase, remote from many known resistance mutations, and may have specific practicality against N1 neuraminidase in H1N1 and H5N1 viruses responsible for all pandemics of the 20th and 21st centuries. The research will enable the potential of these inhibitors to be fully assessed at the molecular level for the first time.Read moreRead less

This project aims to understand how avian influenza virus (AIV) emerges, evolves and spreads in wild birds. AIV has the potential to devastate the poultry industry and cause human pandemics, but the factors that shape the genetic diversity of AIV in its wild bird reservoir are poorly understood. The project plans to combine genomic, ecological and phylogenetic approaches to reveal key aspects of AIV evolution, as well as the risk for future viral emergence. Using sampling sites in Australia and Antarctica, it plans to investigate AIV diversity, the evolutionary dynamics of AIV in wild birds and poultry, and the role played by environmental transmission in AIV ecology.Read moreRead less

This project will reveal the host factors associated with the diversity, evolution and dynamics of viruses using state-of-the-art metatranscriptomics in Australian wild birds. The structure of virus communities and their associated ecological drivers in wild animal hosts remain a black-box, even though they are the largest source of viral diversity in nature. This project expects to generate key insights into host-associated drivers of viral community dynamics and the subsequent effect of anthropogenic factors such as urbanisation and poultry production. Identifying host factors that affect viral ecology in wild birds will constitute a cornerstone in understanding the emergence of virulent viruses and/or their spread to poultry or humansRead moreRead less
