Delineating Aberrant Adaptive Immune Responses Due To Germline Mutations In The PI3K Signalling Pathway

Summary
Activation of immune cells is required to generate appropriate immune responses that protect is from disease caused by pathogens. The inability to receive the correct type of signals causes immunodeficiency. The PI3 kinase pathway is central to immune cell activation – and genetic errors in this pathwat compromise the functioning of immune cells. We will investigate the nature of these defects and pursue avenues of overcoming them using pharmacological inhibitors of the PI3K pathway.
Defining The Requirements For Effective Immune Responses

Summary
The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host. Individuals with primary immunodeficiencies have defects in the development and/or function of the cells of their immune system and are more susceptible to infectious diseases. This study will investigate such individuals to identify functions for specific genes and immune cells in order to understand the requirements for generating effective immune responses ....The immune system rapidly responds to infectious pathogens to eradicate such microbes and limit the damage they can inflict upon the host.

Summary
The ageing of the population is one of the major transformations being experienced by Australia’s population which will have major health implications. Recent studies have shown that many elderly individuals display ‘immune risk phenotype’ (IRP) which is characterised by a severely distorted immune system and human cytomegalovirus (CMV) infection. In this project we will investigate the mechanisms by which CMV alters cellular immune system and thus impacts on the host immunity against other path ....The ageing of the population is one of the major transformations being experienced by Australia’s population which will have major health implications.

In Vivo Imaging Of Virus-specific T Cell Responses In The Skin

Summary
Effective vaccination against many viral infections such as Herpes Simplex Virus (HSV) may be achieved by directing the cells of the immune system to specific sites in the body where they can lie in wait against the disease. To direct the immune system in this way, we must first understand how immune cells orchestrate themselves in tissues. This project will utilise advanced imaging techniques to study immune cells in real time to understand how they protect against viral infections in the skin.
The Generation Of HSV-1 Specific Effector And Memory CD4+ T Cell Responses.

Summary
This proposal aims to determine the mechanisms underpinning the generation of helper T cell responses following HSV-1 infection. It will determine the factors that allow T cells to access sites of viral replication and the mechanisms by which they provide protection from skin infections.
Generation And Maintenance Of Effective T Cell Memory In Peripheral Organs

Summary
Infectious diseases represent potentially life-threatening events. Immunity against re-infection relies on different types of memory immune cells that constantly patrol through the organism in search for invading agents. Recently, it has emerged that there exists an additional type of memory cells that permanently reside in peripheral tissues where they confer immediate immune protection. This project will examine the requirements for the generation and maintenance of this important cell type.
My research centers on the formation and function of T cells, with particular emphasis on normal T cell homeostasis and how T cells respond to foreign antigens while tolerating self antigens.
