Summary
Antibody production is essential for immune responses and regulated by a subset of lymphocytes named T follicular helper (TFH) cells. Consequently, dysregulation of TFH cell function, or expression of TFH cell-associated molecules most likely contributes to the pathogenesis of certain autoimmune or immunodeficient diseases. Knowledge on TFH cells can greatly facilitate the development of new diagnosis and therapy.

Summary
An integral component of an immune response to foreign pathogens is the production of antibodies by B cells. However, if antibodies react to self-antigens (human molecules rather than bacteria or viruses) they may also cause autoimmune diseases such as lupus. This research project is investigating the mechanisms that control antibody generation by B cells, and how these are dysregulated in autoimmune diseases, such as lupus.

Summary
An important class of T cells known as T Follicular Helper cells (TFH) orchestrate the immune response so that we can produce antibodies to fight infection. The novel finding that our Lab made last year is that the molecule interleukin 21 (IL-21) is a growth factor for TFH. The findings we have made thus far could be used in a number of ways. For eg, IL-21could be used to expand numbers of TFH, using them to boost vaccination or natural defences against viruses, bacteria and tumour cells.

Summary
Lupus is a life-threatening disease in which immune responses normally targeted at germs are directed at tissue in the body. We have discovered a mouse model of lupus and elucidated an important pathway that determines whether immunity is directed at the body or at germs. Building on recent progress in understanding the genetic variation between individuals, we will use the information obtained from the mouse model to investigate the genes that regulate this pathway in people with lupus.
