Summary
Interleukin 21 is a molecule which activates B cells. Defects in this pathway cause immunodeficiency where individuals cannot make antibodies, while constant activation has been reported in mouse models of autoimmunity. Examining these pathways will shed light on the causes of human immune disease, and may reveal molecules that could be targeted for the treatment of immunodeficiency and autoimmunity. Amplification of normal immune responses could lead to the development of improved vaccines.

Summary
The aim of this research is to study how white blood cell growth is regulated by signals of the immune system. Problems in this process can have drastic effects on the well being of an individual leading to deficiencies in controlling infection and development of diseases such as cancer. Once we understand how these signals regulate white blood cell growth, we can begin to develop therapies to provide protection against these diseases.

Summary
CD46 is a protein on human cells that viruses and bacteria bind to during infection. Our laboratory has found that binding of CD46 on immune cells impairs their ability to recognize and kill target cells and may explain the immunosuppression caused by measles infection. We aim to investigate the mechanisms behind the effect of CD46 on immune cells. The outcomes of this study will define new paradigms in lymphocyte biology and determine how CD46 influences the immune response to infection.

Summary
Lymphocytes are white blood cells that are involved in producing antibodies, killing defective cells, or killing cells infected with viruses. In recent years, researchers have found ways to harness lymphocytes to develop medicines for treating a variety of different cancers. In this project, we will establish methods to make human lymphocytes in the laboratory from stem cells, paving the way for the broader application of this cell type to new therapies.
I am an immunologist-cell biologist investigating the regulation of human immune responses in health and disease. The overall goal of this work is to improve immunity in individuals with immunodeficiencies, or during vaccination, or to attenuate immune re

Summary
To protect us against infection, surveying immune cells will launch an attack against foreign cells by using complex signalling process to communicate with each other. A novel method in which immune cells differentiate to defend the body against infection has been recently discovered this year and this project will involve dissecting how this occurs. It will involve using state-of-the-art laser-based technologies, combined with studying immune events in cells and intact organs.
