Summary
Our immune system constantly monitors our body for disease-causing microbes, such as bacteria that cause illnesses like pneumonia or tuberculosis. Our cells have a molecular alarm-system called 'MR1' which alerts white blood cells that an infection by microbes is occurring, however this process is not well understood. This grant will allow me to discover the cells and molecular pathways that govern the MR1 alarm system, which may lead to new treatments against common diseases in our community.

Summary
The immune systems of animals have evolved complex but effective mechanisms to protect against infection with intracellular pathogens. This requires that T cells can distinguish uninfected cells from those harbouring pathogens. This is achieved via recognition of pathogen-derived molecules, which activate the immune system to recognise and fight the pathogen. We have identified a crucial role for a gamma delta T cells in this process, making them essential sentinels of intracellular infection.
Identifying Molecular Machinery In Dendritic Cells.

Summary
Vaccines invoke immune responses that will protect a vaccinated host if they encounter infection. Vaccines can also be deployed to fight cancer. 'Dendritic cells' are the key immune cell responsible for vaccine immunity. While dendritic cells are pivotal to initiating vaccination, little is known about their internal machinery. This research proposal will identify new machinery for dendritic cell vaccine immunity that will serve as therapeutic targets to boost vaccination.
