Long Lived, Virus Resistant Resident Memory T Cells

Summary
Vaccines that deposit memory T cells within the lung, gut and genital tract hold enormous therapeutic potential, as these mucosal surfaces are major portals of entry into the body for many viruses. However, the accumulation of large numbers of T cells within the mucosal tissue may increase the number of target cells for T cell trophic viruses (eg HIV) to infect. We will explore factors that are important in the generation of mucosal memory T cells that are also resistant to virus infection.
Characterisation Of The Genetic Networks Underlying Macrophage Differentiation And The Resolution Of Inflammation

Summary
Chronic inflammation is a central player in many common diseases, impacting on the health and well being of millions of Australians. By using innovative genomic approaches to build a map of all of the gene products involved in the inflammatory process, this project aims to identify which are the critical molecules that normally switch off inflammation. Our ultimate aim is to develop new approaches to treating inflammatory disease.
Activated Protein C Suppresses The Abnormal Immune Response In Rheumatoid Arthritis

Funding Amount
$380,558.00
Summary
This project will determine whether activated protein C (APC) reduces the severity of rheumatoid arthritis (RA) by altering the abnormal response of a type of white blood cells known as the T cells. Experiments will utilise T cells isolated from patients with RA, normal controls and an animal model of RA, to examine a newly discovered immune pathway now thought to play a major role in causing RA. The results will help clarify whether and how APC prevents joint destruction in RA
Targeting Central Inflammation To Combat Obesity And Obesity-related Cognitive Dysfunction

Summary
The current obesity epidemic means many of us will suffer from overweight or obesity for at least some of our lives. My findings show obesity can cause inflammation throughout the brain including in regions related to learning and memory. Here I hypothesize that obesity induces long-term changes in the brain’s immune cells, that this can explain why we see susceptibility to cognitive decline in obese individuals, and that we can reverse these negative effects by targeting these immune cells.
Investigating The Mechanism And Consequences Of Cytotoxic Lymphocyte Detachment
Funder

Funding Amount
$419,180.00
Summary
Killer cells are white blood cells that destroy cancerous cells. To move to their next target they must quickly detach from a dying target. Failure of detachment results in excessive inflammation and tumour escape. This project will discover the detachment signals required to ‘release’ a locked-on killer cell. This will lead to a deeper understanding of immune pathology and new ways of treating cancer.
Understanding And Modulating Hyperinflammation Caused By Influenza Viruses

Summary
In humans, highly pathogenic influenza A virus (IAV) infections can be fatal, as the disease is untreatable with available vaccine or anti-viral drugs. My fellowship aims to advance our knowledge of the mechanisms by which the immune system induces and regulates inflammation during IAV infection, which can be both helpful and detrimental in fighting the infection. This is critical for identifying and developing new therapies for severe IAV infections in the future.
Integrated Exploration Of Novel Therapies For Depression

Summary
There is a clear need for new therapies for psychiatric illnesses, particularly depression. Current antidepressant therapy is useful but leaves many with a shortfall to functional recovery. My research program investigates new therapies for depression, in the context of the biological understanding of depression.
Macrophage inhibitory cytokine-1 (MIC-1) participates in cancer, stroke and heart attack. Studies show that measurement of MIC-1 in blood and cancer tissue might be useful to detect the development of cancer and determine whether it will spread. Also, MIC-1 measurement can identify people who are at risk of dying of cancer, heart attack and stroke. This study will show how MIC-1 may be used to prevent, diagnose and help treat these conditions and reduce healthcare costs.
I have discovered particular factors produced by our white blood cells have the ability to shut down or boost protein production in the gut, pancreas and lung. My vision is to harness these to devise new strategies for treatments for infectious and non-infectious diseases (inflammatory bowel disease, diabetes) that have a high burden on our healthcare system.
In Vivo Responses To Pathogen-derived Mediators Of Acute Inflammation

Summary
Sepsis causes large numbers of deaths worldwide. It is not known why some patients tolerate an infection and fully recover, while other patients with an equivalent infection are highly vulnerable to severe illness and death from sepsis. Heart failure is a common underlying condition in sepsis. This research will focus on how an infection can cause sudden cardiac death. It will have implications for care of patients with severe infection and also sudden infant death syndrome.
