Summary
I have developed and established the use of mass spectrometry to identify and quantitate ligands of antigen presenting molecules to understand the breadth of immune responses in a variety of human disease states including autoimmunity, cancer, infection and allergy. By embedding the technology in disease focussed research programs I will define the molecular bases of these diseases and the important immunological targets that will provide new avenues for therapeutic development and vaccines.
Investigation Of The Roles Of Foxn1, Wnts And Autophagy In The Development And Function Of Thymic Epithelial Cells.

Summary
The immune system usually protects the body from infections. Occasionally, the immune system mistakenly recognises components of the body as foreign and attacks them, resulting in autoimmune diseases such as diabetes, multiple sclerosis and arthritis. An organ called the thymus is responsible for educating the immune system, and preventing autoimmune diseases. The proposed project will explore how the thymus develops, and how it teaches the immune system to ignore normal components of the body.
Antigen Presentation During HLA B27 Associated Auotimmune Disease

Summary
Ankylosing spondylitis is a debilitating arthritic disease, susceptibility to which is conferred by genes of the immune system, particularly HLA-B27, and following gastrointestinal infection. Using mass spectrometry we will identify bacterial peptides bound to HLA-B27 on infected cells that may trigger an autoimmune response. Defining the self peptides that remain the targets of autoimmunity will unravel the molecular and cellular mechanisms if disease and identify peptides for immunotherapy.
The Role Of Non-classical MHC Class I Molecules In Adaptive Immunity

Summary
Specialised proteins called MHC class Ia molecules (MHC-Ia) stimulate killer T cells to lyse virus infected cells. In contrast, the function of the closely related MHC-Ib is uncertain. Recent findings have demonstrated that MHC-Ib can also be recognised by T cells and this interaction is important in the control of viral infections. However, despite the similarity to MHC-Ia, it is unclear how this interaction occurs. This project aims to investigate how killer T cells recognise MHC-Ib molecules.
