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
Development Of Cancer Immunotherapy Using Gene-engineered T Cells In A Self-antigen Mouse Model

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.
Enhanced Translation Of Epstein-Barr Virus Nuclear Protein, EBNA1, As A Target Fot T Cell-based Immunotherapy

Summary
Epstein-Barr virus, (EBV) is a human herpesvirus associated with a range of human cancers. EBNA1, an important EBV antigen, was thought to be “immunologically silent” however, recent studies from our laboratory show that EBNA1 is recognized by our body's defence system and these observations raise the possibility that EBNA1 may be an exploitable, immuno-therapy target for treating EBV-associated cancers.
Investigating The Dynamic Interactions Between Immune And Cancer Cells Using Two-photon Intravital Microscopy

Summary
Immune cells normally aid tumour destruction, but in some situations do the reverse and promote tumour spread. We will utilize cutting edge techniques including 2-photon microscopy together with novel transgenic mouse models to track immune cells in real time during tumour development in order to identify what factors determine a positive versus negative outcome. This will give us an unprecedented opportunity to ‘see’ how these cells interact with malignant cells which could lead to novel therap ....Immune cells normally aid tumour destruction, but in some situations do the reverse and promote tumour spread.

Summary
Patients with lymphoma cancers initially respond well to treatment, but later relapse with disease. The immune system can be effective at controlling cancer. A potential treatment option is to boost the natural immune response against cancer. This study investigates a novel vaccine that activates a certain immune cell, NKT cells, to fight lymphomas by delivering an NKT cell-activating molecule. Outcomes will allow assessment of combining an NKT-based vaccine with established treatments for lymph ....Patients with lymphoma cancers initially respond well to treatment, but later relapse with disease.

Anaphylaxis: Pathophysiology, Acute Management, Diagnosis And Immunotherapy.

Summary
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. This award will support research projects that aim to improve both the emergency care of this condition and subsequent immunotherapy (desensitisation) for people who experience anaphylaxis to insect sting. It will also support research to better understand anaphylaxis to antivenoms, which is a major problem worldwide, and to thus improve the treatment of snake, scorpion and spider envenoming.
Tolerance Induction By Antigen-presenting Cell-targeted Antigen

Summary
We have found that by ‘targeting’ antigen to the cells that ‘train’ the immune system we have been able to prevent the development of autoimmune disease. In the research proposed here we aim to develop new ways in which antigens can be targeted to these cells so that this approach can be applied clinically. The proposed studies will also determine how antigens targeted in this way restore self-tolerance and prevent autoimmune disease.
Human Dendritic Cell Subsets And Their Application For Immunotherapy

Summary
Immunotherapy is a promising non-toxic strategy for the treatment of many cancers, viruses and other diseases. It works by teaching the patient's own immune system to recognize and destroy the cancer. Specialized blood cells called dendritic cells are essential to this process but they are poorly understood in humans. I aim to investigate the function these cells and use this information to develop new treatments for cancer and viruses.
