Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Funding Amount
$678,899.00
Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
The Role Of Novel G-Protein Coupled Receptors In Immunity And Inflammatory Diseases

Funding Amount
$69,684.00
Summary
Recent advances in molecular biology techniques have resulted in the identification of many novel GPCRs. Novel GPCRs expressed selectively on immune cells display a potential target for novel therapies for inflammatory diseases such as Asthma and Rheumatoid arthritis. This project aims to define the activity and significance of a novel group of GPCRs, the GPR40 family. Outcomes of this project will be further understanding of immune cell development and inflammatory disease development.
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
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
Elucidating the roles of steroid receptors in mitochondria. This project aims to elucidate the roles of newly discovered steroid receptors in the functions of mitochondria. The project will characterise their impact on cellular respiration, oxidative stress, and the induction of inflammation. By defining these processes in the healthy state and in response to common environmental challenges of infection and smoke exposure, the project will characterise the fundamental biology of entirely new pro ....Elucidating the roles of steroid receptors in mitochondria. This project aims to elucidate the roles of newly discovered steroid receptors in the functions of mitochondria. The project will characterise their impact on cellular respiration, oxidative stress, and the induction of inflammation. By defining these processes in the healthy state and in response to common environmental challenges of infection and smoke exposure, the project will characterise the fundamental biology of entirely new processes of how normal body hormones and administered steroids may function. This may eventually lead to new and more effective ways to control inflammation that will have significant benefits to mammalian health and improve health care and agriculture outcomes.Read moreRead less
Gene Expression Biomarkers Predict Severe Asthma Inflammatory Phenotype, Activation Mechanisms And Treatment Response

Summary
Asthma is now recognised to be made up of several disease variants or phenotypes, which are likely to have different underlying causes and mechanisms. We lack understanding of how to identify phenotypes of asthma and how they work, and this is delaying research that will lead to improvements in treatments and patient care. This is particularly important in people with severe disease. This grant will establish a gene test to identify asthma phenotype, and further understand mechanisms and treatme ....Asthma is now recognised to be made up of several disease variants or phenotypes, which are likely to have different underlying causes and mechanisms.

A Unique Network Of Phagocytic Cells At The Interface Between The Liver And Peritoneal Cavity

Funding Amount
$787,521.00
Summary
This project aims to characterise the nature and ontogeny of a novel population of cells with phagocytic capacity that forms a network underlying the capsule of mouse and human liver reminiscent of that formed by Langherans cells in the epidermis of the skin. In this project we will characterise this newly described liver capsular macrophage subset, define their ontogeny and assess their specific functions.
Targeting Neutrophil Extracellular Traps To Reduce Inflammation In Severe Asthma
Funder
National Health and Medical Research Council
Funding Amount
$585,240.00
Summary
People with severe asthma, a chronic disease of the lungs, often have many inflammatory cells in the airways called neutrophils. Neutrophils release a meshwork of fibers in a web like trap called NETs, which are made of the cells DNA and other proteins that fight infection. These NETs can promote inflammation in the persons airways. Current asthma treatments have no effect on NETs. This project will measure NETs in the airways and test a new treatment to reduce NETs, and relieve asthma symptoms.
The Interplay Between Viperin, Peroxisomes And The Cellular Innate Antiviral Response
Funder
National Health and Medical Research Council
Funding Amount
$556,127.00
Summary
Infection with a virus initiates a cellular antiviral response that attempts to limit viral replication, however how this response is regulated is not well understood. In this proposal we will investigate a cellular protein (viperin) that can regulate this process by interaction with peroxisomes to amplify the antiviral response. This work will provide possible targets for therapeutic manipulation of the innate immune response that will be applicable to a wide range of viral infections.
Arbovirus Activation And Modulation Of NLRP3 Inflammasome

Funding Amount
$779,720.00
Summary
This project aims to establish how mosquito borne viruses such as Ross River and dengue viruses interacts with the human host to cause disease, including how the virus evades the host’s immune response to persist and cause disease for prolonged periods. Knowing how differences in the virus and the host’s immune system interplay to cause asymptomatic to severely disabling disease will assist in devising new treatments and prevention programs to lessen the impact of these diseases in Australia.
