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.
The Control Of Autoimmunity Originating From Somatically Hypermutated B Cells

Summary
Our immune systems are capable of producing long-lived antibodies that can last a lifetime. Sometimes, this powerful process can however become abnormal and result in autoimmune diseases such as lupus. We have recently developed the first experimental mouse model that allows researchers to study this process in great detail. This funding will extend our initial observations by identifying the exact mechanisms by which important regulators of autoimmune disease act.
Lymphocyte Differentiation And Genetics Of Primary Immunodeficiency

Summary
Primary immunodeficiency diseases affect a large number of individuals. Due to abnormal immune responses, these people are at risk of frequent, severe infections, as well as complications of autoimmune disease and cancer. Treatment often involves regular immunoglobulin (antibody) replacement. Through a better understanding of the mechanisms underlying these immunodeficiency diseases, we hope to be able to determine genetic causes, and more cost-effective and targeted treatment options.
Nodal Function In Peripheral Neuroinflammatory Disorders: Target Antigens, Functional Significance And Treatment Response

Funding Amount

Summary
Inflammatory neuropathies are autoimmune disorders which produce severe disability and represent a costly burden to the healthcare system, but the causes remain unknown. Recent evidence from our team suggests that antibodies against parts of the peripheral nerve at the node of Ranvier are involved. The project aims to identify these specific targets and monitor treatment responsiveness, stabilise nerve function and prevent persistent disability.
