Investigation And Therapeutic Targeting Of The Immune Mechanisms That Predispose To And Increase The Severity Of Influenza In Pregnancy
Funder
National Health and Medical Research Council
Funding Amount
$326,097.00
Summary
In pregnancy there is suppression of maternal immunity to enable fetal implantation and growth. Respiratory viruses, like influenza, take advantage of these changes and cause infections that are more severe in pregnant women, affecting them and their babies. In this project we aim to identify specific immune responses against viruses that are reduced in pregnancy that can be selectively boosted. This has the potential to protect against viruses without affecting the pregnancy or baby.
Developmental-associated Dysregulation Of Innate Anti-microbial Immunity In Early Life As A Determinant Of Susceptibility To Atopic Asthma

Funding Amount
$570,334.00
Summary
Previous NHMRC-sponsored research from the applicants has demonstrated that one of the strongest risk factors for subsequent development of asthma is having chest infections during infancy that are so severe that they trigger symptoms of fever and wheeze. It is not known what predisposes susceptible infants to these severe infections, and this project will attempt to define the mechanisms of susceptibility.
Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-tr ....Elucidating the post-transcriptional regulation of mast cell proteases. Mast cells (MCs) are immune cells that protect against pathogens but may induce deleterious inflammation. MC function is mediated by specific proteases that are pre-formed and stored in granules. These proteases have unique yet poorly understood mechanisms of regulation. The aim of the project is to use a novel suite of molecular tools and genetically modified mice to identify the critical regions of transcripts that post-transcriptionally regulate the production and storage of these proteins. The project aims to identify the RNA binding proteins, microRNAs and other novel factors that also regulate them. This is expected to elucidate the post-transcriptional mechanisms of regulation of MC proteases.Read moreRead less
Protective memory T cell immune responses defend our body against pathogens by the rapid induction of killer T cells. This protects us from severe or perhaps even fatal disease. Our work will provide insights to how the body makes these potent ‘footsoldiers’. This work will have important implications for identifying how these immune cells can be manipulated to prevent and treat pathogenic and autoimmune disease and for optimising approaches to vaccination.

FACSAria III - Fluorescence activated cell sorter. Flow cytometry is a technique for counting and examining microscopic particles, such as cells and chromosomes, by suspending them in a stream of fluid and passing them by an electronic detection apparatus. The FACSAria III cell sorter will be used to establish a core facility for sorting cells. The outcomes from using this technology are a better understanding cellular and genetic understanding of cancer, respiratory diseases, reproduction and ....FACSAria III - Fluorescence activated cell sorter.

The Role Of Cross-reactive T Cells In Severe Lung Disease Following Viral Respiratory Infections

Funding Amount
$1,003,390.00
Summary
Why do some patients clinically deteriorate at a greater rate than others during acute respiratory viral infections despite similar or identical clinical management? One explanation is the reactivation immunity towards ubiquitous viruses that then go on to cross-react against the new respiratory pathogen leading to an overly aggressive and destructive response in the lung. We will examine this potential of existing anti-viral immune responses to exacerbate disease in lung transplantation, as suc

How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affec ....How innate lymphoid cells regulate mammalian lung development. This project aims to determine the ability of a subset of lung resident immune cells to promote normal lung development through the regulation of stem cells. The lung is constantly exposed to countless environmental challenges including microbes. Mammals’ local immune systems protect the lung from these challenges. This is particularly important in early-life when the lung is still developing. However, impaired lung development affects humans and livestock, costing >$3 billion p.a. The intended outcome is to identify basic biological processes involved in normal mammalian lung development, which may lead to strategies to prevent chronic lung diseases in humans and animals.Read moreRead less
Priming, Recruitment And Retention Of Influenza Virus Specific CD8 T Cells In The Upper Airways
Funder
National Health and Medical Research Council
Funding Amount
$633,371.00
Summary
Influenza virus gains entry into the body by inhalation and initiates its replication cycle within the upper airways. This early stage of infection, when the amount of influenza virus is low, provides the ideal window of opportunity for an effective immune response to limit disease progression. In this proposal we will define the immunity that can be evoked within the upper airways and determine immune mechanisms left behind that can safeguard this region from this important respiratory pathogen
Mechanisms Regulating Establishment Of Persistent Herpesvirus Infection

Funding Amount

Summary
Herpesviruses are a major cause of disease worldwide and are amongst the most successful human pathogens, with some viruses infecting more than 80% of the world's population. This group of viruses persist and reactivate in hosts and induce immunosuppression.The control of herpesviruses infections thus represents an important clinical goal. Understanding the mechanisms involved in the induction of viral persistence and immunosuppression is a crucial step towards developing better therapies.
Mechanism of action of an anti-inflammatory compound which targets alternatively activated macrophages. The project will study the mechanism by which a novel anti-inflammatory compound, developed by our commercial partner, suppresses the activity of a population of cells known as alternatively activated macrophages. These cells play a key role in driving allergic inflammation, including the inflammation associated with asthma.
