During an immune response a white blood cell, the T lymphocyte, receives a series of signals that manipulate cell survival and proliferation. The team at WEHI will identify the effects of key signals on the molecular control of T cell survival. The results will be used to test a new method for inducing tolerance and dampening unwanted immune responses, such as during tissue graft rejection and autoimmunity.

Summary
The immune response of each individual varies. For some, the response invoked by foreign challenge is weak, leading to a lifetime of difficulty with infection. For others, the response is stronger, yielding excellent immunity, but opening the potential for overactive responses to self-material and autoimmune disease. We have a new theory for how the health of our immune system can be measured and we aim to apply it to understand the genesis of the many different forms of human immune diseases.
Understanding the immune response is proving extremely complex and promising results for disease treatments from animal models are often difficult to translate to new clinical therapies. My research is unearthing weaknesses in our current knowledge of the immune system and seeking to replace them with a foundation that can exploit new developments in computer modelling and systems biology. In this way I aim to rationally manipulate the immune response.

Dendritic cells (DCs) are the body’s sentinels, with three specialized subtypes. They monitor for infections and cancer and then activate immune T cells to clear it. Interestingly, they can all arise from a single cell, but the precise steps are unknown. By literally filming this process and analyzing the movie, we hope to draw the ‘family trees’ that lead to their generation. This knowledge will offer crucial clues as to how to boost or reduce their numbers for medical applications.

Summary
Dendritic cells (DCs) are a type of white blood that kick-start immune responses. There are various types of DCs that specialize in, for example, clearing viral, bacterial or fungal infections, and are even used to fight cancer. Understanding how DCs grow, therefore, has many clinical benefits. This project aims to understand these processes and identify new regulators of their growth using cutting edge technologies and strategies.

Summary
I am an immunologist focused on identifying how B lymphocytes, the cells responsible for producing antibodies, survive and participate in immune responses within the body. I achieve this by using specially designed, genetically modified, mice that allow me to follow B lymphocytes within the body and identify their key genetic and external controls. My work is relevant to vaccine development as well as the control of certain autoimmune diseases and B lymphocyte cancers.
Comprehensive transcriptional mapping of emergent division-linked cell fate decisions. This project proposal will lead to a better understanding of the molecular mechanics that drive certain cellular behaviors. To do this, we will use a frontier technology, RNA sequencing, which we think has the potential to revolutionise Australian science and make Australia an even more attractive place for young researchers.
