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.
The Role Of Co-signalling Receptors In Cytotoxic Lymphocyte Activity During Infection And Cancer

Summary
Cytotoxic lymphocytes (CLs) are immune cells that detect and kill cancer cells. CLs recognise ‘stress’ proteins on cancer cells through specialised receptors, and this provides the signal for them to kill. However, some cancer cells, such as leukemic cells, can interfere with this recognition to avoid killing by immune cells. This project will investigate the mechanism of recognition and killing of cancer cells by CLs, using both mouse models and cells from patients with acute myeloid leukemia.

Summary
Killer T lymphocytes can penetrate tumors and their transfer into cancer patients has demonstrated some encouraging results, but this form of immunotherapy remain ineffective in most cancer patients. We propose to improve the tumor trafficking and anti-tumor activities of killer cells by genetically engineering them with proteins that will enable them to recognise and destroy cancer cells. The outcomes of this project will validate this novel approach for treatment of cancer patients.

We propose to improve the tumor trafficking and anti-tumor activities of killer cells by genetically engineering them with proteins that will enable them to recognise and destroy cancer cells. Our previous work has indicated that killer T lymphocytes can be genetically engineered in culture with tumor recognition receptors. When transferred into mice, these genetically engineered cells can release toxic and inflammatory proteins that cause tumor destruction. In this proposal we wish to further test this approach in mice by enginneering the mouse killer T cells with (i) receptors that provide stronger signals for killing and proliferation; and (ii) with receptors targeting other structures on tumor cells including the tumor vasculature as a means to overcome tumor escape. In addition, we wish to test a novel approach of combining both genetic engineering and vaccination strategies for expanding gene-modified cells after adoptive transfer. These studies will allow the best receptor genes to be transferred to human white blood cells and examined for anti-tumor effects in immune-deficient mice.Read moreRead less
