Summary
The ability to modulate immune responses would have major health benefits. Dendritic cells (DC) are key regulators of the immune system. Different types of DC possess different cell surface molecules and have differing regulatory functions. We have identified four novel DC surface molecules that can be used to target different types of DC. We aim to use antibodies against these molecules to either enhance the effectiveness of vaccines or to suppress autoimmune diseases.

Summary
Some drugs cause adverse reactions that are life threatening. We think these reactions are mediated by killer T cells as they are genetically controlled by immune response genes that normally guide immunity to microbes. We will study immune reactions to the drug abacavir, used to treat HIV (AIDS); allopurinol used to prevent gout and carbamazepine, used to treat epilepsy. The study may also help devise better treatments for patients who experience severe forms of these reactions.

Summary
We here propose to investigate the role of a specific immune-suppressive molecule called CD73 in cancer. We will test the therapeutic activity of blocking CD73 with a monoclonal antibody for cancer treatment, either used alone or in combination with immune-activating agents and chemotherapy.
MicroRNA Networks That Safeguard The Functional Program Of Regulatory T Cells

Summary
A newly discovered group of molecules termed microRNAs are thought to function as rheostats for the activity of genes. We have shown that these molecules are critical for the function of an immune cell type termed regulatory T cells. Without these cells, the immune system is unable to prevent uncontrolled and destructive inflammation. This proposal aims to utilize diverse technologies to uncover the precise molecular mechanisms by which microRNAs safeguard the function of regulatory T cells.
Differentiation of effector and tissue regulatory T cells . Regulatory T cells (Tregs) populate almost every organ of the body and play a central role in preventing inflammation and maintaining health. To exercise these functions, Tregs undergo a developmental program, the details of which are poorly known. This project will utilize newly developed biological tools and state-of-the-art technology to uncover the molecular mechanisms that govern Treg development and function. The project will gene ....Differentiation of effector and tissue regulatory T cells .

The project will generate basic scientific knowledge and new intellectual property that will afford new opportunities for research and development. The outcomes of this project will help to devise strategies to treat diseases such as autoimmunity, cancer and metabolic syndrome, and will thus benefit veterinary and human health.Read moreRead less
The T cell genome in 3D: linking chromatin structure to cellular function. Adaptive immune cell activation results in the acquisition and long term maintenance of specific cellular function that enables efficient immune control of infections. Using advanced cellular and genomic approaches, combined with high-resolution microscopy and cutting edge computational biology, this proposal aims to address major gaps in our knowledge about how alterations in genomic 3D architecture and targeted biochemi ....The T cell genome in 3D: linking chromatin structure to cellular function. Adaptive immune cell activation results in the acquisition and long term maintenance of specific cellular function that enables efficient immune control of infections. Using advanced cellular and genomic approaches, combined with high-resolution microscopy and cutting edge computational biology, this proposal aims to address major gaps in our knowledge about how alterations in genomic 3D architecture and targeted biochemical modifications impact cell specific gene nuclear positioning and how this regulates changes in gene expression associated with immune cell activation. An outcome will be identification of novel molecular mechanisms that will have broad applicability across cellular biology, and provide novel targets for drug development.Read moreRead less
Stress-induced Genomic Instability As A Driver Of Adaptive Responses In Human Cancer Cells

Summary
Growing experimental evidence suggests human cancer cells use evolutionary conserved programs to regulate their mutation rates in response to pharmacological agents, accelerating adaptation and the emergence of resistance. The purpose of our study is to identify the common molecular pathways and genetic mechanisms driving the regulation of mutation rates. Targeting of these pathways using a new generation of “anti-evolution” drugs is an attractive possibility for novel therapeutic approaches.
Using a biosocial approach to advance pandemic influenza control. This project investigates Australia's capacity to cope with pandemic influenza outbreaks, with a special focus on the lives of everyday citizens. By consulting members of the general public and professionals, this project will advise governments on how Australians can be assisted to prepare for the next outbreak of pandemic influenza.
Optimising disease surveillance to support decision-making. COVID-19 has demonstrated the critical role of epidemic data and analytics in guiding government response to pandemic threats, reducing disease and saving lives. The demand for epidemic analytics for response to threats of national significance will only grow. The goals of this project are to 1) determine the combination(s) of surveillance methods that provide the most useful data for epidemic analysis and 2) translate these findings in ....Optimising disease surveillance to support decision-making.

The goals of this project are to 1) determine the combination(s) of surveillance methods that provide the most useful data for epidemic analysis and 2) translate these findings into the blueprint for a next-generation infectious disease surveillance system for Australia. We will use a simulation-evaluation approach, coupling methods from infectious disease modelling with those from information theory optimal design. Outcomes will enable more tailored and effective pandemic response.Read moreRead less
Advancement Of A Personalised Approach To Minimising Infective Complications In Cancer Care

Summary
Managing infections in patients with cancer have become more difficult and unpredictable because of new generation cancer therapies. Measuring the response of the immune system (immune profiling) will allow us to predict which patients will develop infection so that action such as vaccination can be taken to reduce their risk. This program will refine immune profiling to personalise infection care for cancer patients and to introduce it into hospital practice.
