Deciphering IFN Type III, TGF?, IL-10 And Adenosine Pathways In Natural Killer Cells: Enhancing The Innate Anti-metastatic Response Against Breast Cancer Progression

Summary
This project will determine whether one or more factors produced in tumours (eg. cell hormones and metabolites) inhibits NK cells from controlling breast cancer spread using the best available mouse tumour models. We will use genetics to specifically delete response to these factors by NK cells. It is a completely novel approach and this information will allow for the more rational design of cancer treatments following surgery and local radiotherapy and/or chemotherapy.
The Role Of Cytokines In Tumor-induced Immunosuppression

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. We have shown that the cytokine IL-23, plays an important role in cancer initiation, growth and development. My project aims to characterize the cells that produce IL-23 in the cancer microenvironment and define how it suppresses cells of the immune system. A greater understanding of this cytokine’s mechanism of action will enable the rational improvement of treatments for patients with cancer
Control Of Haematological Cancers By Natural Killer Cells

Summary
Haematological cancers affect the blood and lymphoid organs and are generally lethal. Therapies targeting the anti-tumour capacities of the immune system have shown promising results in cancer patients. Natural Killer (NK) cells are key players of anti-tumour immune responses. This project will provide a better understanding of NK cell-mediated control of haematological malignancies that will be directly applied to the design of new curative therapies for blood cancer patients.
Understanding Immunosuppressive Pathways In Cancer

Summary
Cancer-induced immune suppression is a major obstacle to the effective treatment of many cancers. Suppression can be mediated by cells of the immune system, or cancers themselves. My project aims to investigate 3 suppressive pathways and determine their hierarchy in different mouse models of cancer using mouse genetics and antibody-based treatment approaches. Understanding these processes ongoing in the cancer environment will allow the design of more effective cancer therapies.
This Program team will discover new things about immunity to cancer and virus infection and translate the information into novel therapies in patients with blood or solid cancers. The approaches will include new cellular or antibody therapies, alone or in combination. We will determine new predictive biomarkers to better select patients for therapy. We will overcome treatment resistance, improve the safety of combination therapies, and determine their best scheduling and dosing.
This application will increase the impact of cancer immunotherapy on disease prevention and treatment, by developing new targets and novel combination immunotherapies. Outcomes will include an improved understanding of the immune reaction with cancer and more effective strategies to prevent cancer spread and safely target and eradicate a larger proportion of established and advanced malignant disease.

Summary
Immuno-modulators utilize the patient’s own immune system to eliminate or slow the growth of cancerous cells. We have identified a novel immuno-modulator which could be a significant player in immune-modulation therapy for the treatment of cancer. We will use the development grant to develop a product which has significant potential to be the next generation treatment for cancer.
Perforinopathy: Immune-disease Due To Defective Perforin Function

Summary
White blood cells called cytotoxic lymphocytes destroy cancerous cells using special toxic molecules. One of them, perforin, eliminates dangerous cells by punching holes in their membrane. Some individuals that lack perforin become seriously ill in their infancy. Others, that retain some perforin in their lymphocytes can live longer and are at higher risk of developing cancer. We will investigate the causes of partial loss of perforin function and explore novel drug therapies, which should addre ....White blood cells called cytotoxic lymphocytes destroy cancerous cells using special toxic molecules.

Targeting Immune Suppressive Neutrophils To Improve Cancer Immunotherapy

Summary
Cancer is the leading cause of death in Australia. Despite the recent successes of cancer immunotherapies, there is an unmet need to overcome primary unresponsiveness and acquired resistance. Today mounting evidence has accumulated that neutrophils contribute to therapy resistance by fostering tumour blood supply and an immune suppressive microenvironment. The central aim of this project is, to improve cancer immunotherapy by blocking an immune suppressive neutrophil response.
A Role For Double-stranded RNA-dependent Protein Kinase In Regulating Nod-like Receptor Signaling For Modulating Colitis And Colitis-associated Cancer.

Summary
Inflammatory bowel disease (IBD) and Colorectal cancers (CRC) are commonly found in developed countries like Australia. In spite of improved treatment for IBD and CRC, it is still not known why many patients are still not responsive to these therapies. Therefore, this proposed project aims to use genetically modified mice and molecular biology techniques to understand the pathogenesis of these diseases and to find an alternative new treatment for these diseases.
