Allergic inflammation is a type 2 immune disorder classically characterized by high levels of immunoglobulin E (IgE) and the development of Th2 cells. Asthma is a pulmonary allergic inflammatory disease resulting in bronchial hyper‐reactivity. Atopic asthma is defined by IgE antibody‐mediated mast cell degranulation, while in non‐atopic asthma there is no allergen‐specific IgE and more involvement of innate immune cells, such as basophils, group 2 innate lymphoid cells (ILC2), and eosinophils. Recently, protease allergens were shown to cause asthmatic responses in the absence of Th2 cells, suggesting that an innate cell network (IL‐33/TSLP‐basophil‐ILC2‐IL‐5/IL‐13 axis) can facilitate the sensitization phase of type 2 inflammatory responses. Recent evidence also indicates that in the chronic phase, these innate immune cells directly or indirectly contribute to the adaptive Th2 cell responses. In this review, we discuss the role of Th2 cytokines (IL‐4 and IL‐13) and innate immune cells (mast cells, basophils, ILC2s, and dendritic cells) in the cross‐talk between innate and adaptive inflammatory responses.
