Prevention Of Asthma In Young Children Via Immunostimulation

Funding Amount
$679,683.00
Summary
Persistent asthma is a major problem for Australia yet none of the current therapies do more that control the condition. The long-term solution is to prevent asthma from progressing to the persistent form. The major risk factors are: family history, early allergy and recurrent severe lower respiratory infections (sLRI) in the early life. We will conduct a randomized clinical trial to prevent sLRI using a novel bacterial-derived immunostimulant in infants at high risk of developing asthma.
Gastrokine 2 Promotes Gastric Homeostasis And Inhibits Bacterial Pathology

$621,335.00
Summary
Gastrokine 2 is a small regulatory protein secreted by the stomach lining. Its function is unknown but data from our lab suggests that it may be important in maintaining stomach integrity. This project will investigate how gastrokine 2 maintains stomach function, how this can be compromised when bacterial infection is ongoing, and how we might be able to turn up gastrokine 2 expression to prevent inflammation and precancerous changes in the stomach lining.
Cell Surface Mucins In Gastrointestinal Infection, Inflammation And Cancer Development

Summary
Cell surface mucins are protective molecules that line all the wet surface of the body, including the gastrointestinal tract. Our research has uncovered that mucins regulate cell growth and cell death. Inappropriate control by the mucins, could lead to chronic inflammation and formation of cancers. We will test how important these molecules are in the development of cancers in the intestine, and further explore the mechanism of action.
A specialised set of T lymphocytes called Mucosal Associated Invariant T (MAIT) cells react against bacteria and yeast, and reside at mucosal sites where the body's immune defences are most easily breached, e.g. respiratory tract and intestinal mucosa. This study investigates the role of MAIT cells in both protection and pathology in bacterial infections. Controlling MAIT cells could help in treating these conditions.
A Novel Therapeutic Target For Preventing Helicobacter Pylori-associated Diseases

Summary
Gastric cancer mainly results from chronic inflammation (gastritis) caused by the stomach-dwelling bacterium, Helicobacter pylori. We have identified a potassium channel which our data suggest could be a new therapeutic target for protecting against gastric cancer caused by H. pylori infection. This project will test the role of this channel in H. pylori gastritis and see whether drugs that target this channel can protect mice against H. pylori-associated disease.
Adoptive Cell Transfer Incorporating Vaccination (ACTIV) Therapy For Cancer

Funding Amount
$601,950.00
Summary
We have made a breakthrough in a new treatment for cancer that can destroy large tumours in mice. The treatment involves a transfusion of white blood cells and an injection of a vaccine. In this project, we will seek to understand how the treatment works, and apply it to human white blood cells in preparation for a clinical trial in cancer patients.
Generating Stronger And Smarter T Cells For Cancer Therapy

Summary
White blood cells from cancer patients can be modified in the laboratory to react against tumours. These cells can then be given back to the patient, which can sometimes cause cancer regression. However, often the white blood cells lack strength, or they lack the ability to distinguish between tumour and normal tissues of the body. In this project we seek to make stronger and smarter white blood cells that can deliver a lethal hit against tumours without damaging essential organs of the body.
Immune Modulatory Effects Of Vaginal Microbiota Metabolites And HIV Susceptibility
Funder

Funding Amount
$795,110.00
Summary
This study will advance knowledge on how acid molecules produced by beneficial and harmful bacteria are able to promote or impede HIV infection of the female genital mucosa through their effects on the barrier and immune function of cells that line the vagina and cervix. The results of this study are anticipated to augment the efficacy of topical HIV prevention strategies and lead to the development of safe vaginal hygiene products that help protect against other sexually transmitted infections.
The Axis Of Bcl-2, Plasmacytoid DCs And Lupus As A Basis For Therapy

Funding Amount

Summary
Systemic lupus erythematosus (SLE) affects 1 in 1000 Australians, mostly women. Here the immune system goes awry and makes antibodies against the body’s own components including the body’s DNA. This leads to damage to many parts of the body including kidneys, joints, brain and heart. It is incurable. A particular immune cell controls the development of this disease and we have found this cell is selectively killed by an inexpensive drug, which we hope will be a better way of treating SLE.
Generation Of Protective Immunity Against Severe Influenza Disease In Indigenous Australians

Funding Amount
$1,630,970.00
Summary
Hospitalisation and death rates from influenza are high in the Indigenous population, especially when a new virus emerges. There is an urgent need for a vaccine that protects against all influenza strains. T cells recognising conserved viral regions elicit such protection. As T cells are restricted by proteins called HLAs, which vary across ethnicities, we will define T cell regions for HLAs prominent in Indigenous Australians and define how to generate protective immunity against influenza.
