Summary
This project aims to characterise the nature and ontogeny of a novel population of cells with phagocytic capacity that forms a network underlying the capsule of mouse and human liver reminiscent of that formed by Langherans cells in the epidermis of the skin. In this project we will characterise this newly described liver capsular macrophage subset, define their ontogeny and assess their specific functions.
The immune system must be tightly regulated to make sure that it makes the right response to effectively fight off infection whilst avoiding inappropriate responses that cause damage such as in autoimmunity, inflammation or allergy. This project studies patients who have genetic defects that affect their immune systems and make them susceptible to infection and/or harmful immune responses. This will reveal some of the critical signals that maintain immune control.
The lymphocyte plays a vital role in our immune defence. When lymphocytes encounter a foreign invader, such as a virus, they make a series of decisions that influence the strength, type, and longevity of the immunity created. This program aims to understand how lymphocytes make decisions at the molecular level that affect cell and whole of system level behaviour. We aim to improve vaccines and understand diseases such as allergy, lupus, arthritis and leukaemia to develop novel therapies.

Summary
The cell types of the blood, such as red and white blood cells, are produced in the bone marrow from a rare stem cell. The stem cell uses a handfull of important master-regulatory genes that act in a hierarchy to promote the blood cell differentiation process. This research aims to understand how these master-regulators function in isolation and together in producing the white blood cells that are required for our immune response to microbes, vaccination and to prevent cancer.
The development of better ways to prevent and treat influenza infection will be a major step forward in lessening the impact of the virus in communities worldwide. We have assembled a research team of seven groups who will determine the ways in which the effects of influenza can be mitigated through an understanding of the factors which lead to severe disease, and how these can be lessened by novel vaccination and treatment strategies.
