It has become increasingly clear that interleukin-33 (IL-33) plays a crucial role in initiation of type 2 immunity. The last decade of intense research has uncovered multiple mechanisms through which IL-33 targets key effector cells of the allergic immune response. Recently, IL-33 has been implicated in shaping the immune system of the lungs early in life, at a time which is crucial in the subsequent development of allergic asthma. In this review, we will address the current literature describing the role of IL-33 in the healthy and diseased lung. In particular, we will focus on the evidence for IL-33 in the development of immune responses in the lung, including the role of IL-33–responsive immune cells that may explain susceptibility to allergic sensitization at a young age and the association between genetic variants of IL-33 and asthma in humans. Finally, we will indicate areas for potential therapeutic modulation of the IL-33 pathway.
