Research Interests

Interleukins play a critical role in regulating antibody production, inflammation and haematopoiesis. Dysregulation of these factors can lead to the manifestation of diseases such as asthma, autoimmunity and leukaemia. Our goal is to decipher how these interleukins interact in vivo during haematopoiesis and immune responses providing insight into basic immuno-regulatory mechanisms and identification of novel pathways for therapy.

We are focussed on the molecular regulation of type-2 immune responses including parasite infections and allergic asthma, which are characterised by the cytokines IL-4, IL-5, IL-9 and IL-13.

Recently we have focussed on the cells and molecules that initiate the type-2 response. We have shown that IL-25 and IL-33 play important roles in the up-regulation of type-2 immunity, and in combination with the generation of IL-13-reporter mice we have discovered a novel innate lymphoid cell that we termed the nuocyte. These type-2 innate lymphoid cells (ILC2) play critical roles in protective immunity to helminth parasite infection, and allergy and asthma.
