Resolving Human Immunodeficiency Virus (HIV) Transmission

Summary
To increase the breadth of HIV prevention strategies, it is imperative that we biologically understand how HIV enters our bodies. Through two unique clinical cohorts, we will determine why circumcision is protective and how a commonly acquired sexual transmitted infection (human papilloma virus) can increase HIV transmission.
Identification Of Host Factors That Restrict Influenza Virus Replication In Macrophages

Summary
Influenza virus infects different cells in the airways, including immune cells (macrophages) and non-immune cells (epithelial cells). Epithelial cell infection results in virus amplification and release whereas macrophage infection leads to virus destruction. This project will identify cellular factors expressed by macrophages that block virus amplification and release. Identification of novel antiviral factors is an important step towards developing strategies to reduce influenza disease.
Hepatitis C Virus infects 3% of the world's population causing recurring liver disease, cirrhosis and hepatocellular carcinoma. To infect a liver cell, the viral glycoproteins attach to cell surface molecules wher they are activated to mediate merger of the viral and cellular membranes. This project grant will explore how the viral glycopropteins become activated and obtain essential structural information on the viral glycoproteins. These studies will help us to design antiviral agents.
I am a virologist carrying out research to determine the mechanisms underlying rotavirus cellular tropism and the pathogenesis of rotavirus disease. Rotavirus is the major cause of infantile gastroenteritis worldwide. I am combining the expertise of my group in rotavirus biology with the power of inter-disciplinary collaborations in the areas of sugar chemistry, cell biology, structural biology and diabetes to expand understanding in these areas.

Cell Surface Lectin Receptors For Attachment And Entry Of Influenza Viruses Into Cells Of The Innate Immune System

Funding Amount
$530,094.00
Summary
Influenza virus is a leading cause of respiratory infection and death worldwide. Infection of humans is initiated when the virus contacts cells lining the respiratory tract. Infection of epithelial cells leads to virus amplification whereas infection of immune cells results in virus destruction. Despite extensive research efforts, it is not clear how the virus infects these cells. This project aims to identify receptors on human cells used by influenza virus to attach to and infect immune cells.
Immune Cell Interactions And Cell Signalling Pathways Important For Rotavirus Infection

Funding Amount
$343,812.00
Summary
Rotaviruses are the main cause of severe diarrhoea in Australian children, through infection of the gut cells that absorb food. This project aims to understand the effects of rotaviruses on the functioning and survival of these cells at the molecular level. It will similarly determine the effects of rotavirus infection on the immune cells. These studies will increase understanding of how rotaviruses cause disease, and assist in the development of drugs or improved vaccines against rotavirus.
