Research Achievements
I have been fascinated by the cellular immune system since my undergraduate project in 1989 under the supervision of Professor Andrew McMichael. During my subsequent DPhil in Professor McMichael’s laboratory, I was part of an exciting group and shared in the achievements of the team. This included the first application of the use of HLA tetrameric complexes to questions relevant to disease pathogenesis (HIV) and the identification of CD94 as being a ligand for HLA-E. I wanted to apply my T cell knowledge to the understanding of human skin disease, as dermatology is my clinical speciality. One of the earliest achievements was working with Professor Vincenzo Cerundolo in which we showed that individuals with vitiligo have high frequencies of circulating melanocyte-specific T cells – this has been confirmed in many subsequent studies by others, and a potential role of such T cells in disease has been suggested by the acquisition of pigment loss in patients with melanoma treated with melanocyte-specific T cell infusions. Since having my own group under the support of an MRC Senior Clinical Fellowship, I have focused on atopic skin disease. We have made several contributions, including the identification of type 2 innate lymphoid cells (ILC2) in the skin of humans, and a further infiltration in eczematous lesions and after allergen challenge. We have defined cytokine and lipid mediators that promote ILC2 activation, with therapeutic implications which we are investigating in a current clinical trial. More recently, in collaboration with Professor Cerundolo, we have found that allergens generate neolipids which are novel ligands for CD1a, and can be presented to CD1a-restricted T cells from human skin. We believe that this is an important finding, not only for CD1a and Langerhans cell biology, but for many forms of cutaneous inflammation and is a key focus of our ongoing work. I continue to do two clinics per week in dermatology at the Churchill hospital. This has been invaluable as a resource for understanding disease and for access to clinical samples from well-defined cohorts and the translation of our findings to clinical trials.
What are the Future Aims of Your Current Group
The overall aim of the group is to understand the pathogenesis of cutaneous inflammatory disease in order to identify new approaches to disease prevention and treatment. The studies will contribute to our understanding of the interaction between the epithelium and the innate and adaptive immune response. Emphasis will be focused on: 1) understanding mechanisms underlying CD1a presentation of lipid antigens to T cells in the skin; 2) characterising the function of ILC2 in the skin, and the therapeutic implications; 3) how filaggrin insufficiency promotes atopic inflammation and whether this can be therapeutically modified; 4) investigating mechanisms underlying the cellular immune response to viral antigens in human skin. As well as contributing to disease and tissue specific questions, these studies will advance the broader Unit aims of defining the interactions between the innate and adaptive immune responses and the local micro-environment, which in turn will support the development of new approaches to vaccination and treatment.
How do the aims of your research fit with the aims of the WIMM and Division of Medicine?
The work of the group is directly informed by clinical observation from patients we see in clinic, and is then translated back to the patients. This is illustrated, for example, by the ILC2 work above, which is being explored through a clinical trial. We aim to understand disease by studying samples from humans, but also using models, as required, to investigate underlying mechanisms that may lead to opportunities for therapeutic intervention. In particular, I believe that the CD1a work is likely to be significance in many human skin diseases. As well as scientific research to contribute to the understanding and management of human disease, we are also contributing to the training of scientists and academic clinicians. Over the last 10 years, there have been 10 DPhils completed, of which 6 were by clinicians – there are five current DPhil students in the laboratory. There have been many others in training who have had periods in the laboratory including MSc students, medical students, academic F1/F2, clinical lecturers, academic clinical fellows and overseas visitors. We aim to function within networks to enhance opportunities for success, including integral links with the NIHR BRC, NHS, NIHR Comprehensive Research Network and we participate in local and multicenter clinical trials. The work involves local, national and international collaborations - key collaborators are Vincenzo Cerundolo, Paul Klenerman, Andrew McKenzie (LMB), Branch Moody (Harvard). We also contribute to the work of the institute towards the public understanding of science, including participation in National Science and Engineering Week (several talks) and the Royal Society Summer Exhibition (2002).
Lay Summary of Research
We are working towards treatment and prevention of skin disease. The skin is often the first point of contact with microbes and allergens, but relatively little is understood about how the cutaneous immune system clears these challenges. Such knowledge is vitally important to understanding the mechanisms of skin disease and related diseases, and for developing more effective ways of cutaneous drug and vaccine delivery.
It is increasingly clear that skin barrier dysfunction is an important first step in the development of atopic eczema, one of the commonest skin diseases in the UK, and often associated with asthma and rhinitis. The barrier dysfunction promotes entry of allergens and microbes which eventually lead to skin inflammation. The latter is treated with topical immune suppressants, but these are not curative and also carry risks of side effects.
We wish to understand the steps linking barrier dysfunction and skin inflammation, as these will provide opportunities for new treatments. In particular, we will explore ways to repair barrier function and to understand the roles of novel immune cells in contributing to the inflammation.
These findings will have implications for atopic eczema, but also for other forms of inflammatory skin disease and indeed for the improvement of vaccine delivery in to the skin.
