Summary
The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue in ....The majority of patients who become infected with hepatitis C virus (HCV) are unable to mount an effective immune response and clear the virus and therefore develop lifelong (chronic) infection. The persistence of virus in the liver of patients with chronic infection results in the recruitment of significant numbers of immune cells, notably T cells, from the bloodstream into the liver where they are involved in both viral control (but not viral clearance) and liver injury. The level of tissue injury observed and the speed of disease progression may be linked to the type of T cells recruited, their function, and their position in the liver. The aims of this project are to determine the factors involved in the fine positioning of T cells in the liver and establish a relationship between T cell recruitment, function, and progression of HCV disease in the liver.Read moreRead less
Characteristics And Mechanisms Of Persistent Asthma After Common Cold Virus Infection

Summary
Asthma is a major health problem for the Australian community. Recent studies have shown increasing numbers of people of all ages are developing asthma, and despite a fall in asthma deaths, large number of people continue to have severe attacks requiring hospitalisation. In most cases the deterioration in asthma symptoms is related to a cold or flu like illness. Viruses are the leading cause of these infections and are known to make asthma symptoms worse.

Recent studies have shown increasing numbers of people of all ages are developing asthma, and despite a fall in asthma deaths, large number of people continue to have severe attacks requiring hospitalisation. In most cases the deterioration in asthma symptoms is related to a cold or flu like illness. Viruses are the leading cause of these infections and are known to make asthma symptoms worse. We have identified how viruses do this by triggering a type of inflammation in the airways. We have also found that after a severe attack of asthma some people do not recover completely. They appear to have persistent problems, and in some cases the virus can still be isolated from the airways. How and why this occurs is not known. We are seeking to understand this problem and describe how it affects people with asthma. We plan to investigate what effect certain viruses have on the lungs of people with asthma by measuring cells and chemicals that are present in sputum. We will use recently developed technologies to accurately see what viruses are infecting these people, and how the immune system is working. This study will shed important light on potential causes of unstable asthma and the role that viral infection plays in this. It may also lead to new opportunities to develop treatments that are more effective in preventing and controlling asthma.Read moreRead less
Genetic Dissection Of Biofilm Development By Non-typeable Haemophilus Influenzae

Funding Amount

Summary
The bacterial pathogen non-typeable Haemophilus influenzae (NTHi) is a common cause of chronic infections of the middle ear and of the airways of patients suffering cystic fibrosis, or chronic obstructive pulmonary disease (COPD). These infections are associated with bacterial biofilms that are significantly resistant to both antibiotics and immune defences. This project aims to characterise the process of NTHi biofilm development so that novel diagnostic tools and therapeutics can be developed.

Funding Amount
$5,997,916.00
Summary
Improving Health Outcomes in the Tropical North will strengthen partnerships with research institutions in the NT, Qld, WA, NSW, Vic and SA, by undertaking a research agenda that will help close the gap in Indigenous health disadvantage, protect the north from emerging infectious threats and engage regional neighbours. We will establish a northern Australian network that incorporates Indigenous engagement, mentoring and knowledge translation, and facilitates collaboration with southern partners.
Determinants Of The Outcomes From Infectious Diseases

Summary
This Fellowship will allow Professor Lloyd to continue clinical and laboratory research in two areas: firstly, in relation to prevention of transmission of hepatitis C infection, and scale up of antiviral treatments, particularly amongst prisoners. Secondly, in studies investigating the biological basis of chronic fatigue states following acute infection or cancer treatment, and also in development of effective treatment for chronic fatigue states.
I am an infectious diseases physician and basic scientist interested in the immunopathogenesis of HIV and hepatitis B virus. My work focuses on HIV viral reservoirs and immune reconstitution and the adaptive immune response to hepatitis B virus.
Finding Therapeutic Targets For An Opportunistic Human Fungal Pathogen

Summary
Penicillium marneffei is a fungus that causes disease in patients with depressed immunity. This project models this infection in zebrafish, which have advantages for modelling infectious disease. It uses fluorescent fungi and fish with fluorescent immune cells to study the way white blood cells fight this infection, and mutant zebrafish and mutant fungi to find new therapeutic targets in the host-pathogen interaction.
