The roles of novel pathways in the activation and regulation of the adaptive immune response in health and disease. The immune system is designed to protect us against infection and vaccines exploit this with great success in preventing many infections. However, the immune system can also 'fail' and attack the body in a process called autoimmunity e.g. destroying joints in rheumatoid arthritis. This proposal will define how white blood cells work to make better vaccines against infection and ho ....The roles of novel pathways in the activation and regulation of the adaptive immune response in health and disease.

However, the immune system can also 'fail' and attack the body in a process called autoimmunity e.g. destroying joints in rheumatoid arthritis. This proposal will define how white blood cells work to make better vaccines against infection and how these same immune cells can malfunction to create autoimmune diseases like Crohn's disease.Read moreRead less

Summary
c-Cbl is a member of a multi-adaptor protein family that can interact with many signalling proteins via its different domains. Cbl proteins have been implicated as negative regulators of signalling pathways involving protein tyrosine kinases (PTKs). PTKs are enzymes which add phosphate groups to tyrosine residues on other protein substrates, and the process of tyrosine phosphorylation acts as a potent biochemical switch to turn signalling cascades on and off.

Cbl proteins have been implicated as negative regulators of signalling pathways involving protein tyrosine kinases (PTKs). PTKs are enzymes which add phosphate groups to tyrosine residues on other protein substrates, and the process of tyrosine phosphorylation acts as a potent biochemical switch to turn signalling cascades on and off. Studies of Cbl-deficient (knockout) mice show that Cbl proteins are important in regulating the development of, and signalling by, cells of the immune system called T cells. c-Cbl knockout mice show greatly enhanced PTK-signalling responses and deregulated activity of a PTK called ZAP-70. The mechanism of this is not known, but analysis of a c-Cbl mutant mouse shows that this is not dependent on the tyrosine kinase binding (TKB) domain of c-Cbl. Therefore other functional domains of Cbl must be responsible for the increased signalling response in the c-Cbl knockout mouse. One candidate is the highly conserved RING finger domain which can modify Cbl-associated PTKs by addition of ubiquitin molecules. Ubiquitination of a protein often, but not always, leads to its degradation, and this could be how Cbl controls the strength and duration of signalling in T cells. However there may be other functions of the conserved RING finger yet to be identified. c-Cbl itself is prominently and very rapidly modified by tyrosine phosphorylation on tyrosine 737 by the Fyn PTK following T cell activation, but the role of this modification is not known and could also be essential for c-Cbl s function in T cells. We plan to investigate the roles of the RING finger domain and Fyn-mediated tyrosine phosphorylation in c-Cbl regulation of T cell signalling by analyzing knock-in mice that carry specific mutations disrupting the RING finger or tyrosine 737 in the c-Cbl gene.Read moreRead less

Summary
An unfortunate consequence of immune function is that occasionally rogue immune cells are produced that attack the host and lead to the development of so-called autoimmune diseases such as arthritis. Normally a white blood cell called a regulatory T cell suppresses these self-reactive immune cells. We have identified factors that govern the generation of regulatory T cells. Understanding how these factors work should permit the development of new strategies to combat autoimmune diseases. ?
