The airway inflammatory response is closely associated with asthma. The purpose of this article was to study the roles of innate lymphoid cells (ILCs) in the process of airway inflammatory response in asthma. We established the asthmatic mice model with intraperitoneal injected ovalbumin medium, then with the flow cytometry analysis, we detected the ILCs and their surface proteins in the mice blood samples, besides, we analyzed the amounts of inflammatory cytokines and secreted proteins in the mice bronchoalveolar lavage fluid and blood serum. Moreover, Western blot analyzed the proteins in the mice bronchial epithelial tissues. The ILC2 amounts were obviously increased in young asthmatic mice model. And, the proteins CD25 and CCR10 were highly expressed in the sorted ILC2s. Besides, the cytokines interleukin (IL)-5, IL-13, IL-33, CCL22, and CCL27 were abundant in the bronchoalveolar lavage fluid of asthmatic mice model. And, the secretion of IL-5, IL-13, IL-33, TSLP, and CCL22 in blood serum was much more in asthmatic mice model than in the normal control mice, whereas the secretion of PGD2 was suppressed in asthmatic mice bronchoalveolar lavage fluid and blood serum. Additionally, the guanine nucleotide-binding proteins Gα12 and Gα13 were upregulated in asthmatic mice bronchial tissues, and the protein SERCA2 was downregulated; moreover, the proteins NFAT, IRF4, and its downstream signal STAT6 were all upregulated in the asthmatic mice bronchial tissues. ILC2s were involved in the response of airway inflammation through secretion of proinflammatory cytokines and chemokines to dysregulate the Ca homeostasis in airway in the process of asthma.
