Some infections can start inflammation that, while controlling the infection, can also attack the body tissues of genetically susceptible people. This inflammation can initiate long term problems including arthritis, diabetes and cancer. Our research program seeks to understand who is genetically at risk of this sort of problem and why, and thus to develop new means to prevent and treat the chronic diseases that are initiated in this way.
Immune Privilege Of The Hair Follicle: Implications For Alopecia Areata
Funder

Summary
The skin, the second largest organ in the body after the skeleton, is of primary importance to the survival of mammalian life. Hair follicles are complex skin appendages, problems of which have an impact on human health and emotional welfare disproportionate to their small dimensions. In this study we will investigate the role of the immune system in the hair loss disease, alopecia areata, one of the most common human autoimmune diseases with the aim of finding more effective avenues of treatmen ....The skin, the second largest organ in the body after the skeleton, is of primary importance to the survival of mammalian life.

Characterisation Of Autoreactive T Cells In Chronic Idiopathic Urticaria Would Improve Its Diagnosis And Treatment.

Summary
Chronic idiopathic urticaria (CIU) is a disease in which itchy hives recur due to no apparent trigger. It is an autoimmune disease in which the immune system reacts against certain cells in the skin, called mast cells and basophils. It is unclear how this occurs. Once activated, mast cells and basophils release a chemical called histamine, which is responsible for the rash. I aim to identify the immune reactions that occur in CIU, develop reliable tests for diagnosis and improve treatment of CIU ....Chronic idiopathic urticaria (CIU) is a disease in which itchy hives recur due to no apparent trigger.

RELapses PrevENTion In Chronic Autoimmune Disease: Common Mechanisms And Co-morbidities (RELENT)

Funding Amount
$499,837.00
Summary
Treatment of people with chronic autoimmune and inflammatory diseases is not optimal, as we do not know how intensively to treat people, and current treatments often have significant side effects. The RELENT program aims, using multiple approaches, to gain a deeper and more useful knowledge of why these diseases are occuring, what might indicate that disease requires more treatment, and which treatments will be most targeted and have the fewest side effects.
The Role Of NF-?B Transcription Factor RelA In Regulatory T Cell Homeostasis And Function

Summary
Treg cells constitute an immune regulatory cell population that is essential for the prevention of fatal autoimmunity; however, they also limit immunity against cancer. We have discovered that the factor RelA is of critical importance for Treg development and function. We now aim to illuminate the functions of RelA in detail. Understanding the molecules that impact on Treg cell biology is critical to harness their potential for clinical intervention such as treatment of autoimmunity and cancer.
In Vivo Investigation Of Human PR3 Transgenic Mice: A Novel Animal Model To Understand The Role Of PR3 In Chronic Inflammation And Autoimmune Vasculitis

Funding Amount
$378,615.00
Summary
Granulomatosis with polyangiitis (GPA) is a form of vasculitis and is associated with antibodies directed against proteinase 3 (PR3). PR3 is expressed in neutrophils, monocytes and macrophages and has a number of well-characterized pro-inflammatory functions. The aim of this project is to understand the role of PR3 in inflammation and autoimmune vasculitis in vivo. This will be achieved using a transgenic mouse model expressing human PR3.
Exploring The Contribution Of Interferon-lambda To Autoimmune Disease

Summary
We have found that a novel protein, normally made in response to viral infections, is found in the blood of Lupus patients. This project will determine the cells that make this protein, what in Lupus blood makes these cells produce it and whether it plays a role in the severity of Lupus disease.
Pathogenesis Of A New Mouse Model Of Ankylosing Spondylitis

Funding Amount
$682,820.00
Summary
Ankylosing spondylitis and Crohn's disease are autoimmune inflammatory diseases which cause long-term pain and deformity of joints, spine and bowel. Using a new mouse model of both diseases, we will study cells and processes involved in the initiation of disease, in order to discover new targets for prevention and treatment. The work will have importance for design of new therapies for human inflammatory spine and bowel diseases.
