Summary
There is an unmet medical need to develop new immunotherapies that are safer and potentially allow the treatment of a broader range of cancers. Inhibiting the immune checkpoint CD96 function represents an opportunity that may parallel and indeed complement the activity and impact of other lymphocyte checkpoint inhibitors in human cancer (eg. CTLA-4 and PD1/PD-L1). While developing a new human therapeutic antibody we will also learn more about an important checkpoint in the immune response.
Investigating The Anti-tumour Efficacy And On Target Toxicity Of Gene-modified T Cell Therapy In Vivo

Summary
White blood cells from cancer patients can be modified in the laboratory to react against tumours. Although these cells can induce cancer regression when given back to the patient, these cells can often cause associated pathology. In this study we propose to fully investigate the limits of this type of therapy for mediating anti-tumour responses and potential toxicity in mouse models that closely recapitulate the human setting. These studies will lead to a more effective therapy for patients.
Strategies To Enhance CD4 T Cell-mediated Anti-tumour Immunity

Summary
The immune system is capable of controlling cancer, but frequently does not do so. In this project we will study two factors that compromise anti-cancer immune responses: regulatory T cells, which suppress immune responses, and tolerogenic dendritic cells, which subvert potentially beneficial responses to tumours. By manipulating these factors, we hope to enhance the effectiveness of the immune response against cancer.
Understanding The Role Of B Cells In Gastric Cancer For The Design Of New Therapeutic Strategies

Summary
Gastric cancer is the 2nd most common cause of cancer-related death worldwide. Our laboratory has previously established clinically relevant mouse model of gastric cancers, and our preliminary results indicate a strong link between B cell tumor infiltration and gastric cancer progression. In this project, we aim to elucidate the role of B cells in gastric cancer and determine whether B-cell targeted therapy alone or in combination with chemotherapy can be beneficial against this malignancy.
The Role Of The Transcription Factor Blimp-1 In Tumour Immunity

Summary
Regulatory T (Treg) cells function by suppressing immune system activity, ensuring that our immune system does not mount a response against our own tissue. In cancer, Treg cells suppress anti-tumour immunity, facilitating tumour growth. Recently we have identified a group of active Treg cells that may be the key drivers of immune response regulation. Our work will examine the role of these active Treg cells in tumour immunity, opening the door to more effective targeting of Treg cells in cancer.
Utilization Of Gene-engineered T Cells For Enhancing Cancer Immunotherapy

Summary
Killer T lymphocytes can penetrate tumours and their transfer into cancer patients has demonstrated some encouraging results, but this form of therapy and other approaches including vaccination remain ineffective in most cancer patients. In this project, we propose to improve the tumour trafficking and anti-tumour activities of killer cells by genetically engineering them with proteins that will enable them to recognise and destroy cancer cells, whilst minimizing toxicity to normal tissue.
New Strategies For Enhancing Chimeric Antigen Receptor (CAR) T Cell Therapy For Cancer

Funding Amount
$849,540.00
Summary
The role of the immune system in cancer is now recognised as highly important, highlighted by the success of immunotherapy in patients. Yet many patients fail to respond to this form of treatment due to low frequency of lymphocytes present at the tumor site. A new form of immunotherapy involving transfer of gene-modified lymphocytes is a potential way to overcome this problem. This project will explore new strategies to enhance the utility of this approach against blood and solid cancers.
Identification And Targeting Of A Potent NK Cell “checkpoint” In Tumour Immunity

Funding Amount

Summary
Cancer must evade detection by the immune system in order to develop. Natural Killer (NK) cells can detect and kill cancer cells. We have discovered a potent "checkpoint" in the NK cell activation pathway that desensitizes NK cells to growth factors and switches off their activation and killer function. When this checkpoint is inhibited, NK cells become hyper-activated and prevent most types of cancer metastasis in mice. Targeting this checkpoint in humans could revolutionise cancer therapy

Summary
Cancer must evade detection by the immune system in order to develop. Natural Killer (NK) cells can detect and kill cancer cells. We have discovered a potent "checkpoint" in the NK cell activation pathway that desensitises NK cells to growth factors and switches off their activation and killer function. When this checkpoint is inhibited, NK cells are super activated and can prevent most types of cancer metastasis in mice. Targeting this checkpoint in humans could revolutionise cancer therapy.
