Type-2 immune responses are important for combating parasitic worm infections but can also result in allergies and asthma. Molecules involved in the initiation of type-2 immune responses can serve as potential targets for therapeutic intervention. Interleukin-33 (IL-33) has been shown to be a potent inducer of type-2 inflammatory response mainly through its effects on T1ST2 receptor expressing immune cells. However, the mechanisms of its secretion and possible nuclear function in the IL-33 producing cells remain to be elucidated. My work focuses on the molecular mechanisms of IL-33 action in a context of an inflammatory response.
