It is abundantly expressed in lung epithelial cells and plays an important role in both innate and adaptive immunity. In innate immunity, IL-33 responds promptly to produce an immune response that maintains homeostasis. In adaptive immunity, IL-33 interacts with various immune cells. At the same time, IL-33 also plays an important role in chronic inflammation of the airway and its remodeling. This article reviews the relevant biological knowledge of IL-33 and its research progress in lung immunity, and discusses the related issues of IL-33 as a lung immune test site and therapeutic target.展开更多
