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.

Immunotherapy is a new approach to treat cancer, and works by promoting the immune system to attack cancer. Immunotherapies, such as checkpoint blockade and adoptive T cell therapy, are proving to be very successful in certain human cancers. However, combining immunotherapy with drugs that cause cancer cell death may be more effective. This project will investigate the potential of combining immunotherapy with a novel anti-cancer drug, in order to develop more effective treatments for cancer.
T-cells: The Key To Unlocking Immunity Against Aggressive Lymphoma

Summary
By investigating several aspects of patients’ immune defenses against the cancer cells in Diffuse large B-cell lymphoma, this project will provide critical insights on ways to harness the patient’s own immune system to effectively mount anti-tumour responses. These results will pave the way for future therapeutic strategies to successfully treat and prevent lymphoma.
Targeting Adenosine Mediated Immunosuppression To Enhance CAR T Cell Activity

Summary
The use of white blood cells genetically engineered to eradicate cancer cells specifically has been a major breakthrough in cancer treatment. These cells (CAR T cells) are very effective in blood cancers, but do not currently work well in other cancers. This is due to the immune suppressing nature of the cancer environment. I propose to use strategies to overcome this by genetically reprogramming the CAR T cells to be resistant to suppression by the cancer and therefore be more effective.
Analysis Of Killer T Cell Geometry During An Anti-tumour Response

Summary
Cancer is a major health problem around the world. Currently used treatment options of cancer have the drawback that they also damage healthy tissues. This limits the dosages that can be administered, frequently resulting in treatment failure. Anti-tumour killer T cells are a naturally occurring cell type that can cause tumour regression. In the present proposal, we explore how the efficiency of these cell-types can be further enhanced to induce rejection of progressing tumours.
The Role Of The Actomyosin Cytoskeleton In T Cell-mediated Anti-tumour Immunity

Funding Amount
$616,950.00
Summary
T cells, specialised immune cells, are crucial in the defence against tumours. In order to reach cancerous target cells, T cells must enter tumour tissues from the blood stream and then effectively migrate in the extravascular space. This application aims to uncover the role of the cytoskeleton, a group of molecules driving cell shape change and motility, in the efficient execution of T cell anti-tumour function. These studies will aid the development of improved immunotherapies against cancer.
Overcoming Resistance To Cancer Immunotherapy By Targeting MET-signaling In Neutrophils

Summary
Cancer is a leading cause of death in Australia. The human immune system is able to attack cancer cells. However, cancer cell can escape the destruction by cytotoxic cells. The development of novel immunotherapies has revolutionized cancer therapy, but only a subgroup of patients is responding. This research project aims to identify novel combinatorial therapies blocking immune suppressive neutrophils to improve anti-cancer immunity and survival of cancer patients.
