Research Expertise

Description

I run a translational medicine research programme focused on investigation of pathogenesis and discovery of biomarkers of disease in glomerulonephritis. My principal research interest is in ANCA vasculitis, an autoimmune condition that causes multi-organ failure as a consequence of overwhelming necrotising inflammation affecting small blood vessels. We are addressing the following questions: 1. What biomarkers accurately track glomerular and extra-renal inflammation in ANCA associated vasculitis? 2. What molecular and cellular events prevent resolution of vasculitic injury after the initial insult? 3. What underpins the large variability in clinical phenotype observed in ANCA associated vasculitis? 4. How can we minimise the adverse events associated with existing immunosuppressive therapies? To assist in answering these questions, we have set up infrastructure that allows collection of longitudinal clinical data in the form of a national registry and biobank, which is linked to a basic science laboratory.

Projects

  • Title
    • Irish Rare Kidney Disease Registry and Biobank
  • Summary
    • We aim to recruit, register and biobank all incident patients with systemic vasculitis in Ireland. Much effort is put into ensuring the first sample set is obtained before any treatment is given. Subsequent longitudinal sample sets are obtained over the next 5 years. This is being run in collaboration with the Tallaght Vasculitis and Allergy Group

    • The acute, untreated patient with vasculitis: enhancing recruitment and sampling using a national network
  • Summary
    • The Tallaght Vasculitis and Allergy Group (TVA Group) aims to provide joined up, efficient and excellent care to patients with systemic vasculitic and allergic conditions by developing a strong multi-disciplinary alliance within Tallaght Hospital. By combining the academic strength of the members, the group also aims to maximise research funding credibility and to provide a mechanism for national and international research network engagement. The RKD biobank and registry is an established infrastructure which feeds into the academic arm of the TVA Group. It is co-chaired by Mark Little and Peter Lavin on behalf of the group. Its goal is to capture long-term longitudinal clinical data and high quality biological samples from patients with systemic vasculitic and allergic disorders, disease controls and healthy controls. Coordinated from Tallaght Hospital, it currently receives data and samples from five centres across Ireland and has been actively recruiting since September 2012. In this relatively short period of time it has become one of the most important bio-resources in this field globally. To maximise its potential we now wish to target a specific patient group for recruitment: those with very active disease who have not yet been treated with immune suppressing medication. These are very challenging to recruit as they can present at any time of day or night and need to be sampled very rapidly (usually less than one hour) - hence these type of patients are virtually absent from existing biobanks around the world, despite being the most valuable in studying the disease. By extending recruitment to the whole country using the current grant proposal, we believe we can recruit an additional 70 such patients, making the biobank unrivalled anywhere, and an invaluable resource for discovering new biomarkers and studying disease mechanisms in these rare diseases.

  • Title
    • Interplay between Interferon-alpha and low density granulocytes in ANCA vasculitis: a key pathogenic pathway underpinned by NETosis?
  • Summary
    • Anti-neutrophil cytoplasm autoantibody (ANCA) vasculitis (AAV) is a severe, systemic autoimmune disease, and one of the leading causes of progressive glomerulonephritis,which often results in kidney failure. It is a neutrophil driven disease, with antibodies targeting the neutrophil granule proteins myeloperoxidase (MPO) and proteinase 3(PR3. Binding of ANCA to these antigens leads to inappropriate neutrophil activation,and subsequent damage to endothelial cells, with consequent chronic, unresolving vascular inflammation. The reason for the loss of control over this neutrophil-initiated inflammation is unknown; 1. There is strong recent evidence that the ANCA-induced release of neutrophil extracellular traps (NETs) plays an important role in AAV pathogenesis. NETs are composed of nuclear chromatin, histones and antimicrobial proteins and are released in process called NETosis, a specialised form of neutrophil death. 2. Interferon á (IFNá) is upregulated in AAV patient serum and is strongly associated with an increased risk of glomerulonephritis. Interestingly, IFNá can prime neutrophils to undergo NETosis in response to C5a, a proinflammatory complement protein fragment shown to be important in ANCA-associated glomerulonephritis, and it is likely that IFNá also enhances ANCA-induced NETosis. 3. A number of studies have identified a subpopulation of low-density granulocytes (LDGs), with all the characteristics of neutrophils, that co-purify with peripheral blood mononuclear cells (PBMCs). Compared to normal density neutrophils (NDGs), these show a markedly enhanced propensity to NETosis, and to release IFNá. Our preliminary data show that LDGs are present in relatively high numbers in patients with AAV. Thus, we hypothesise that LDGs in AAV are capable of inducing tissue damage via IFNá production, which primes both NDGs and LDGs to undergo NETosis.

  • Title
    • Probing the metabolic response to vasculitic injury: towards a tool for non-invasive monitoring of immune activation in ANCA vasculitis
  • Summary
    • The objective of the proposed work is to identify a non-invasive marker of immune activation in AAV. I will incorporate pre-clinical and clinical tools to study the urinary metabolomic signature at various stages of active, inactive and tolerant AAV. This project will require biobank development including patient recruitment and sample processing. We will then develop an in vivo model of anti-myeloperoxidase (anti-MPO) AAV. The urinary metabolomic signature of the in vivo model and patient samples will be interrogated using mass spectroscopy. Bioinformatics expertise and statistical modelling will then be undertaken to identify a sensitive and specific urinary metabolomic signature of immune activation in AAV. I will then collaborate with University College London Centre for Nephrology and the Immune Tolerance Network and interrogate the urinary metabolomic signature in tolerant patients. These results will then be validated by development of an in vivo model of tolerant AAV. Metabolomics is the non-targeted measurement of all metabolites produced by the body, it is a promising area in biomarker development. It has been used to identify biomarkers in other kidney diseases including acute kidney injury and polycystic kidney disease.

    • Determining the breadth and burden of Chronic Kidney Disease in Ireland: Associations with cognitive impairment, functional decline and quality of life
  • Summary
    • Chronic kidney disease (CKD) is a major health problem all over the world. At least 1 in 10 adults are estimated to have kidney disease. Some of these people will progress to end-stage kidney disease which requires dialysis treatment or a kidney transplant for survival. However the majority of people with CKD do not survive long enough to reach end-stage kidney disease because of high rates of early-onset heart disease and premature death. What is driving these poor outcomes in people with CKD is not fully understood. The extent to which kidney disease affects Irish people is unknown. There is an urgent need for precise information about the impact of CKD in Ireland, so that healthcare resources can be directed at those that need them most. The Irish Longitudinal Study on Ageing (TILDA) has gathered detailed health information on a representative sample of over 8000 members of the Irish general population aged 50 years and over. As CKD is predominantly a disease of older age, TILDA is the perfect setting in which to study this disease. The goals of the proposed research are three-fold: to determine the rates of all stages of CKD in the Irish general population; to explore the impact of CKD on the physical and cognitive health of Irish older adults; and to identify those people with CKD most at risk for complications, whom we expect would benefit most from medical intervention. This important research will provide critical information to policy makers towards developing and implementing a national strategy designed to improve the health of Irish people with kidney disease.
