The group is well known in the area of herpesvirus immunology and have published numerous scientific papers in leading medical journals. This program grant focuses on two human herpesviruses. The first is called Epstein-Barr virus which causes glandular fever and is associated with arange of human cancers. The second virus is human cytomegalovirus which can cause birth defects and problems in transplant patients. In this program we are investigating how the body�s immune system controls these viruses to exploit this information to develop new treatments.Read moreRead less
Cytokine Production By Human Dendritic Cells - Is Less More?

Summary
Dendritic cells (DC) are specialist white blood cells responsible for initiating and coordinating immune responses against pathogens and cancer. DC act as sentinels of the immune system and are found throughout the body where they are in constant surveillance for infections or danger signals. Once armed they traffic to the lymph nodes, where they activate T lymphocytes and NK cells, which are then responsible for mounting an attack against the infection or tumour.

DC act as sentinels of the immune system and are found throughout the body where they are in constant surveillance for infections or danger signals. Once armed they traffic to the lymph nodes, where they activate T lymphocytes and NK cells, which are then responsible for mounting an attack against the infection or tumour. The complex mechanisms of how dendritic cells respond to danger, and how they direct T and NK cells to induce specific immune responses appropriate for a particular infection are poorly understood. Most of our current knowledge of DC has been obtained from mouse studies, and it is believed that secretion of cytokines by dendritic cells play an important role. Human dendritic cells have been difficult to identify, however we have pioneered methods to isolate and characterise them from human tissue. We will therefore investigate the production of cytokines from human DC subsets and the role they play in the induction of immune responses. DC can be instructed in the test tube to recognise a cancer and mount an immune response, and this is a promising new therapy for cancer. Our work will uncover fundamental information about the most potent danger signal, the type of DC and the most important cytokines for inducing immune responses against cancers, and will therefore assist in the development of cancer vaccines.Read moreRead less

Summary
Specialized white blood cells called dendritic cells (DCs) are essential to inducing the immune system to eradicate cancers and viral infections in mice. We have defined human DC subsets and related their functional capacities to the mouse DC subsets. We will now identify the human DC subsets involved in the induction of cancer and viral immune responses and use this information to develop clinical therapeutic cancer vaccination trials.
I am an immunologist, working to understand the function of NKT cells, and how these cells can be manipulated as a means of immune therapy for a range of immunologically related diseases.
Analysis Of Antigen Receptor Sharing By T And B Lymphocytes

Summary
To survive an infection the immune system must rapidly expand the number of immune cells that have pathogen-specific receptors that recognise, and therefore specifically combat, the infection. This normally occurs through proliferation of the immune cells. We have found that in addition to proliferation, the number of cells with these receptors can be increased by a process of receptor transfer between cells. This grant aims to further advance our understanding of this novel phenomenon.
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.
Chronic infections and cancers are major causes of global disease burden. Harnessing the immune system to combat these diseases has proven difficult and cumbersome to date. We invented a new technology to boost the ability of the immune system to fight chronic infections such as AIDS and Hepatitis C. This involves using someone�s own blood treated with sets of short proteins. We term this therapy Overlapping Peptide Pulsed Autologous CelLs (OPAL). This shows great promise in robust animal models ....Chronic infections and cancers are major causes of global disease burden.

My research is aiming to study how the immune system controls viral infections in transplant patients and use this information to bolster their immunity in a test tube, providing protection against a virus the patient is unable to fight after their transplant. We are also trying to develop new strategies to use patient's own blood cells which will be grown in the laboratory and returned to the patient, resulting in a full recovery.

Summary
We plan to develop the instruments and associated technologies required to directly visualise biological processes as the occur in real-time deep inside living organisms. Thus we will use two-photon microscopy to provide deep tissue imaging of immune cell interactions in mouse models and confocal endomicroscopy to provide molecular imaging of cancer biomarkers in patients with colorectal cancer.
