Summary
People with lupus are at increased risk of heart attack and stroke. For women aged 30-44 the risk is as much as fifty times higher than in women without lupus. Only some of this risk is due to well known factors like high blood pressure and cholesterol. We are looking at other possible causes of heart attack and stroke in people with lupus - with blood tests and heart scans. We hope this will identify who is at risk and what can be done to prevent them from suffering a heart attack or stroke.
Bring Out Your Dead - How Does Defective Apoptotic Cell Clearance By Tingible Body Macrophages Lead To The Activation Of Self-reactive B Cells In SLE?

Summary
Good housekeeping is critical to the day-to-day running of the immune system. In the case of the germinal centre, a key structure where plasma cells are generated, the ability to clear away dead and dying cells is critical because failure to do so can lead to the spillover of cellular waste and debris into the follicle where they can activate harmful B cells to make autoantibodies and cause disease. Understanding how this happens can lead to new ways to target and treat autoimmune diseases.
B Cells And Autoantibodies In The Pathogenesis Of Hypertension

Summary
This project aims to gain a better understanding of the causes of hypertension. Specifically, we will test the idea that activation of the immune system and the production of antibodies is a major cause of the blood vessel and kidney damage that leads to high blood pressure. Such findings could pave the way for new treatment approaches where drugs currently reserved for patients with autoimmune diseases (e.g. rheumatoid arthritis, gout) are re-purposed for the treatment of hypertension.
Molecular Signatures Of Public Clonotypes In Human Systemic Autoimmunity

Summary
New platform technology has been developed to study autoantibody clones in lupus and Sjogren's syndrome. This approach has furthered our understanding of these disorders by the discovery of unique sets of clones that are common to all patients. The unique "molecular signatures" of these clones can be translated to a next-generation diagnostic that detects them in patients at extremely low levels missed by conventional tests.
Platelet Receptor Regulation In Autoimmune Disease

Summary
In response to bleeding, blood platelets use receptors to form a thrombus (blood clot) and block further loss of blood and aid tissue repair. People treated with heparin prior to surgery, can form autoantibodies that attack platelets, leading to thombus and thrombocytopenia (dangerous loss of circulating platelets). This is a significant clinical problem that is difficult to diagnose. We will determine how platelet receptor shedding can aid the diagnosis of heparin-induced thrombocytopenia.
The Mechanism For Combined Immunodeficiency And Autoimmunity Due To STK4-deficiency And Its Broader Application To Human PIDs

Summary
Why do some patients develop autoimmune diseases such as lupus where the immune system makes antibodies that attack its own body? To answer this, we plan to study a disease where a gene responsible for making antibodies is defective. Patients with mutations in the STK4 gene are unable to regulate the selection processes by which only the right cell is chosen to make antibodies. Understanding how STK4 works may help us unlock the mystery of what causes lupus.
