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.
Role Of Complement Factor H And Related Proteins In Regulating Complement Activation And Microbial Pathogenesis

Summary
A group of proteins in blood called Complement are activated in the presence of foreign cells or organisms and this generally results in their destruction. It is important to direct this destructive activity against foreign and not self tissue. This is achieved by a further family of proteins, including factor H, which regulate complement activity and how these proteins work is the principal focus of this project. There are many diseases in which damage results from inadvertent complement damage ....A group of proteins in blood called Complement are activated in the presence of foreign cells or organisms and this generally results in their destruction. It is important to direct this destructive activity against foreign and not self tissue. This is achieved by a further family of proteins, including factor H, which regulate complement activity and how these proteins work is the principal focus of this project. There are many diseases in which damage results from inadvertent complement damage and the regulatory proteins have therapeutic potential in this area. In addition many bacteria and other microorganisms, which should be destroyed by complement, escape by binding regulatory proteins. Understanding how this is achieved may reveal new targets for vaccine development. Knowledge of how the production of factor H and related proteins will help understand how inflammation occurs and how it might be controlled.Read moreRead less

Summary
A group of proteins in blood called 'Complement' are activated in the presence of foreign cells or micro-organisms and this generally results in their destruction. It is important that this destructive activity is directed against foreign and not self tissue. This is achieved by a further family of proteins, including a protein called factor H, which switch off or regulate complement activity. How these proteins work is the principle focus of this project.
