Current research projects:

Epigenetic regulation of lymphocyte differentiation and function. T cells can be programmed into different functional subsets that can promote or suppress inflammation and disease. Differentiation and functional plasticity of T cells is dependent on the epigenetic regulator Ezh2 (Tumes et al, Immunity, 2013). We are using modern technologies such as chromatin immunoprecipitation followed by next generation sequencing (ChIP-Seq) to provide a global view of gene regulation in T cells. This information is being used to determine how T cell differentiation and plasticity is regulated and to define new ways to control T cell function in diseases such as allergy and cancer.

Allergic disease of the airways. Airway mucosal tissue is a specialised barrier capable of protecting against infection while allowing airflow to the lungs and absorption of oxygen into the body. Inflammation of the airways results in accumulation of immune cells in lymphoid structures close to the mucosal surface. We are using cutting edge techniques such as single cell RNA-Sequencing and a human airway tissue xenograft model to dissect the inflammatory pathways operating in patients with upper airways disease.

Allergic disease of the skin. The skin is the largest barrier tissue in our body and provides both physical and immunological protection from infection. Mast cells are activated via antigen-mediated cross-linking of IgE bound to their surface, a process that is centrally involved in inflammatory skin diseases such as atopic dermatitis. We are defining novel signalling pathways that regulate IgE-driven mast cell activity and testing new topically applied drugs to inhibit allergic skin diseases.
