Interleukin-33 (IL33), also known as NF-HEV and DVS 27, is a cytokine belonging to the IL1 superfamily. IL33 is a pro-inflammatory protein that may regulate gene transcription and induce helper T-cells, mast cells, eosinophils and basophils to produce type 2 cytokines. The induction of type 2 cytokines by IL33 in vivo is believed to induce the severe pathological changes observed in mucosal organs following administration of IL33. IL33 is constitutively expressed in smooth muscle and airway epithelia, and it binds to a high-affinity receptor family member ST2. In vivo administration of mature IL33 promotes increased production of IL5, IL13, IgE and IgA, as well as splenomegaly and inflammatory infiltration of mucosal tissues.
