Long Lived, Virus Resistant Resident Memory T Cells

Funding Amount

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.
The Inflammasome In Host Defence And Autoinflammation

Summary
Inflammation is one of the bodies first responses to infection. The inflammasome is a protein complex that activates pro-inflammatory cytokines as part of this process. We are investigating pathogens that activate a specific inflammasome complex, and also an inflammatory disease it may cause when activated accidentally, in the absence of infection. We are also investigating pathways that keep this inflammation in check, and how pathogens might hijack these anti-inflammatory pathways to promote i ....Inflammation is one of the bodies first responses to infection.

Competition For Polarity Influences Lymphocyte Differentiation And Function

Summary
CD46 is a protein on human cells that viruses and bacteria bind to during infection. Our laboratory has found that binding of CD46 on immune cells impairs their ability to recognize and kill target cells and may explain the immunosuppression caused by measles infection. We aim to investigate the mechanisms behind the effect of CD46 on immune cells. The outcomes of this study will define new paradigms in lymphocyte biology and determine how CD46 influences the immune response to infection.
Host-pathogen Interaction: The Battle For Supremacy

Funding Amount
$480,014.00
Summary
This grant will provide salary support for Dr Rowena Bull. Dr Bull's research is focused on understanding the disease process between the human host and the infecting virus. The outcomes of this research will be used to find novel ways to fight viral infections with vaccines and drugs.
HIV is one of the highest public health priorities of our time. Traditional vaccines have been unsuccessful highlighting the need for alternative approaches to HIV vaccine design. We propose to modify a novel technology developed initially for targeted drug delivery, termed “capsules”, for the purpose of inducing an immune response. This is a generic technology with applications for other infectious diseases and cancer and brings together disparate disciplines of nanochemistry and immunology.
Molecular Regulation Of Tissue-Resident Memory T Cell Differentiation

Funding Amount
$419,180.00
Summary
A recently identified subset of T cells that reside at points of pathogen entry are critical to combat viral infection. However, little is known about how these T cell populations are formed. This project will characterise the pathways required to generate these cells and will identify novel factors that regulate their development. A greater understanding of how these T cells can be generated will open the way to utilise these cells in new vaccine strategies.
Generation And Persistence Of Effective T Cell Immunity Towards Seasonal And Pandemic Influenza Viruses
Funder

Funding Amount
$451,716.00
Summary
Introduction of a new influenza strain into human circulation leads to a rapid global spread of the virus (e.g. H1N1 2009 pandemic) due to minimal antibody immunity. Established T cell immunity towards conserved viral regions promotes rapid recovery. However, it is unclear what determines the effective T cell immunity towards influenza. We will define the optimal human T cell populations, with the ultimate goal of improving vaccine design so it protects against seasonal and pandemic strains.
Dendritic Cells In Innate Immunity And Their Potential Clinical Manipulation

National Health and Medical Research Council
Funding Amount
$443,946.00
Summary
Dendritic cells (DC) are rare cells that are crucial in response to infection and surveillance of damaged tissues. We aim to understand the tools that are expressed by DC that allow them to sense pathogens and the functions of different DC types once a pathogen has been detected. The ultimate aim is to be able to understand and harness the functions of different DC so that we may directly target them upon demand to aid in the course of infection or potentially as tumour therapy.

Summary
Patients with lymphoma cancers initially respond well to treatment, but later relapse with disease. The immune system can be effective at controlling cancer. A potential treatment option is to boost the natural immune response against cancer. This study investigates a novel vaccine that activates a certain immune cell, NKT cells, to fight lymphomas by delivering an NKT cell-activating molecule. Outcomes will allow assessment of combining an NKT-based vaccine with established treatments for lymph ....Patients with lymphoma cancers initially respond well to treatment, but later relapse with disease.
