Abstract:
Cang-ai volatile oil (CAVO) is an aromatic Chinese medicine and is widely used to treat upper respiratory tract infections in children. However, the mechanism of CAVO in asthma treatment is unclear. In this study, we investigated the effects of CAVO on airway inflammation and the mechanism of inhibiting Group-2 innate lymphoid cells (ILC2s) in asthmatic mice, which was induced with Ovalbumin (OVA). CAVO improved AHR and airway inflammation in asthmatic mice. CAVO reduced the production of interleukin (IL)-2, IL-4, IL-5, IL-6, IL-7, IL-9, IL-13, IL-25, IL-33, and thymic stromal lymphopoietin (TSLP) in the bronchoalveolar lavage fluid (BALF), while increased the production of IL-10, significantly. CAVO also inhibited the suppressor of tumorigenicity 2 (ST2) and IL-33 expressions in the lung tissue. Moreover, flow analyses demonstrated that CAVO inhibited ILC2s activation by reducing the sedimentation of its upstream cytokines, thus alleviating downstream cytokines. This could be because of the downregulated microRNA-155 and upregulated microRNA-146a. CAVO inhibits ILC2s activation, thus further attenuating airway inflammation and AHR in asthmatic mice. These effects may be related to the downregulation of microRNA-155 and upregulation of microRNA-146a.
