Funding Amount
$841,114.00
Summary
T cell responses are important to establish protection against pathogens and some cancer via generation of memory cells that can be maintained long term and defeat promptly re-infections. This proposal aim at determining important factors that drive the success of immunological memory by employing single cell technologies and unique longitudinal samples from subjects infected with hepatitis C virus. The finding of this study will inform current vaccine research and immunotherapies.
Novel Serological Tools To Aid Malaria Elimination In The Asia-Pacific

Funding Amount
$1,362,749.00
Summary
In 2014 Asia-Pacific leaders pledged a malaria free Asia-Pacific by 2030. We will contribute to this goal by developing novel antibody detection tests that can identify people with current and recent past infections. We will then evaluate the utility of these tests both in mass screening and treatment programs and for the rapid delineation of areas where transmission persists from those where it has been eliminated. This will address two major roadblocks to malaria elimination in our region.
Molecular Networks And Genomics Of Host Response In Typhoid Fever

Funding Amount
$487,814.00
Summary
Typhoid fever affects 25 million people annually and is caused by systemic infection with Salmonella Typhi or Paratyphi. With this proposal, we will characterise how different individuals respond differently to typhoid, what ramifications this has for systemic Salmonella infection in humans, and how typhoid can be clinically identified early on, thus giving the patient the best possible chance to avoid complications, injury and potential death.
Extracellular Cues Compete With TCR Signalling To Alter Lymphocyte Polarity, Fate And Function.

Summary
Following an infection, our immune system generates a large and diverse repertoire of cells required to mount and regulate an appropriate immune response. The signals that control the different types of immune cells that develop, and how bacteria and viruses influence immune cell development, are not fully understood. This project will investigate the regulation of immune cell development, and how competing signals from infectious agents influence this process.
Immune Recognition Of Upper Airway Microbiota In Early Life As A Determinant Of Respiratory Health In Children

Funding Amount
$1,135,837.00
Summary
The study will investigate the impact of respiratory infections during infancy on lung & immune function & respiratory health between 3-7 years of age. Children were previously enrolled in a population based birth cohort study (ORChID study) which collected detailed information about the respiratory health during the first 2 years of life with daily respiratory diary & weekly nasal swab collection. In this study lung function & immune function will be assessed annually in the same children (3-7)
Anti-viral Immune Dysfunction In Severe Asthma Varies Across Inflammatory Phenotypes.

Funding Amount
$997,153.00
Summary
Common cold viruses often trigger asthma flare-ups , but have relatively minor effects on healthy people. Why this happens is not clear. We have identified two different ways in which the immune system can react badly to a common cold virus in people with asthma. In this study we will find out more about why the immune system does not react normally in a large group of people with severe asthma. This study will help us discover improved treatments that can be targeted to people with asthma.
Current anti-HIV therapies can't cure HIV because HIV remains silent(latent) in long-lived cells. The HIV life cycle and virus production is linked to activation of the host cell, which is regulated by dendritic cells. This grant will explore how the factors controlling T cell activation and proliferation control virus expression and latency. By understanding how latent infection is established and maintained, these studies will potentially identify new ways to eliminate HIV infection.
An Investigation Into The Adaptive Immune Response In Celiac Disease
Funder
National Health and Medical Research Council
Funding Amount
$597,167.00
Summary
Celiac Disease (CD), an autoimmune-like disease that is triggered by the ingestion of dietary wheat gluten, or related proteins from rye and barely, affects ~1% of the population, causing tissue damage in the small intestine. The only available treatment is strict adherence to a lifelong gluten free diet. Our project aims to understand, at the molecular level, how components of the immune system and gluten interact to trigger the immune response that leads to CD symptoms.
Enhancing Vaccine Efficacy By Harnessing Dendritic Cell Receptors And Their Unique Properties

Funding Amount
$687,519.00
Summary
Potent vaccination might be achieved by using monoclonal antibodies as magic bullets to target vaccines to special cells in the body. We show that targeting these special cells by using monoclonal antibodies that recognise Clec9A is effective, perhaps because it brings several different immune cells together so that they orchestrate very efficient immune responses. This application investigates how targeting Clec9A allows strong vaccination so that we can apply this to new generation vaccines.
In Vivo Imaging Of Virus-specific T Cell Responses In The Skin
Funder
National Health and Medical Research Council
Funding Amount
$332,258.00
Summary
Effective vaccination against many viral infections such as Herpes Simplex Virus (HSV) may be achieved by directing the cells of the immune system to specific sites in the body where they can lie in wait against the disease. To direct the immune system in this way, we must first understand how immune cells orchestrate themselves in tissues. This project will utilise advanced imaging techniques to study immune cells in real time to understand how they protect against viral infections in the skin.
