Summary
The innate immune system is the first line of defense in protecting the body from infection. Phagocytic (meaning eating) white blood cells, which include dendritic cells and macrophages are equipped with cell surface proteins These bind the many types of microbes that cause infection, allowing the phagocytes to destroy them (innate immune response). Furthermore, dendritic cells and macrophages have mechanisms to activate additional specific responses (adaptive immune response) mediated by lympho ....The innate immune system is the first line of defense in protecting the body from infection. Phagocytic (meaning eating) white blood cells, which include dendritic cells and macrophages are equipped with cell surface proteins These bind the many types of microbes that cause infection, allowing the phagocytes to destroy them (innate immune response). Furthermore, dendritic cells and macrophages have mechanisms to activate additional specific responses (adaptive immune response) mediated by lymphocytes (T and B cells). We have discovered a cell surface protein, termed DCL-1, which may play a role in uptake of microbes by phagocytes and activation of innate and adaptive immune responses. This project will examine the mechanisms whereby DCL-1 mediates these immune responses. Understanding the mechanism may allow us to exploit DCL-1 for tumor immunotherapy.Read moreRead less
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.
Defining The Role Of B Lymphocytes In Breast Cancer At Single-cell Resolution

Summary
B cells, a type of immune cells, are likely protective against breast cancer, albeit through unknown mechanisms. Over the next 5 years I will apply high-resolution profiling and imaging of B cells within breast cancer biopsies to understand their contribution and identify novel clinical targets, leading to better patient outcomes.
The Regulation Of B Cell Differentiation And Survival In Response To Antigen Challenge

Funding Amount

Summary
Antibodies are crucial to health and well being but can cause disease if their production is not controlled appropriately. This research program examines the basis of antibody production in normal situations and in situations where it is causing illness, in diseases like system lupus erythematosus (SLE) and in cancers of antibody producing cells called multiple myeloma (MM). The aim is to enable control of the process to achieve better health outcomes and better management of disease.

Summary
Virus infected cells and cancer cells are recognised and eliminated from our body by specialised cells called T-cell lymphocytes. This recognition process is the key step in the immune response and some fundamental questions in immunology are centred on the nature of this process. At the molecular level, the recognition is mediated by the specific interaction between proteins on the surface of the cells.

This recognition process is the key step in the immune response and some fundamental questions in immunology are centred on the nature of this process. At the molecular level, the recognition is mediated by the specific interaction between proteins on the surface of the cells. On the T-cell lymphocyte, the T-cell receptor (TCR) binds specifically to a protein called the MHC on the surface of the target cell. The target cell can be a cancer cell, or an infected antigen presenting cell (specialised cells in the body which present protein fragments (peptides) on their surface via MHC). The structure of a TCR and TCR-MHC have been solved in terms of the shape of the molecules at atomic resolution, bringing detailed information on how these two proteins interact with each other. In this proposal the structural basis of antigen presentation and recognition in cell-mediated immunity will be determined by three-dimensional structures of different peptides on MHC by x-ray crystallography. Cell surface antigen presentation by MHC molecules is crucial for initiating the cellular immune response against invading pathogens and cancer. This proposal encompasses a combined biochemical, immunological, and biophysical approach to understand the range of ligands which can bind to MHC which are subsequently recognised by the TCR. To understand the antigenic properties of modified peptides at the structure level, the x-ray structure of MHC with modified bound synthetic peptides will be determined.Read moreRead less
