Summary
B-Cells of the immune system need a growth factor named 'BAFF' to grow and survive. Elevated levels of BAFF have been detected in patients suffering from autoimmune diseases like lupus and arthritis, and B-Cell cancers like myeloma. This study will determine the identity of the chemical messages that BAFF sends to B-Cells, and how these facilitate B-Cell growth and survival. This will provide a framework for the design of targeted drug therapies that reduce the severity of BAFF related diseases.

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.
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
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.
