Astragalus membranaceus, a traditional Chinese herb, has been used to improve airway inflammation and asthma. The present study investigated whether A. membranaceus has immunotherapeutic effects on asthma, a chronic inflammatory mucosal disease that is associated with excess production of IgE, eosinophilia, T helper 2 (Th2) cytokines, and bronchial hyperresponsiveness. An ovalbumin (OVA)-induced, chronic inflammatory airway murine asthma model was used to examine the status of pulmonary inflammation after the administration of A. membranaceus. The IgE levels in serum and bronchoalveolar lavage fluid showed a tendency to decrease after the administration of A. membranaceus. The number of eosinophils decreased and infiltration of inflammatory cells and collagen deposition declined in lung sections after A. membranaceus administration. The RNA and protein levels of Th2 cytokines and the ratio of the GATA3/T-bet mRNA levels decreased after A. membranaceus treatment. Furthermore, the mRNA level of peroxisome proliferator-activated receptor γ (PPARγ), a nuclear hormone receptor, increased in the lung tissues of A. membranaceus–treated mice. Finally, an A. membranaceus water extract activated PPARγ activity in either human embryonic kidney 293 (HEK293) or A549 cells in a PPARγ-responsive element-containing luciferase reporter assay. These results indicate that A. membranaceus has an inhibitory effect on airway inflammation in a murine model of asthma through modulating the imbalanced relationship between Th1 and Th2 cytokines.

Abstract BackgroundExposure to toluene diisocyanate (TDI) is a significant pathogenic factor for asthma. We previously reported that receptor for advanced glycation end products (RAGE) plays a key role in TDI-induced asthma; however, the mechanism is not clear. Epigenetic alterations of histone deacetylase (HDAC) are associated with allergic asthma. However, its effect in TDI-induced asthma is not known. The purpose of this study was to determine the role of RAGE and HDAC1 in the regulation of airway inflammation using a TDI-induced asthma model.MethodsBALB/c mice were sensitized, and challenged by TDI to establish murine asthma models. FPS-ZM1 (RAGE inhibitor), JNJ-26482585 and romidepsin (HDAC inhibitor) were given intraperitoneally before each challenge. The human bronchial epithelial cell line 16HBE was stimulated by TDI-human serum albumin (TDI-HSA) in vitro. RAGE knockdown cells were constructed and evaluated, and MK2006 (AKT inhibitor) was used in in vitro experiments.ResultsIn the TDI-induced asthmatic mice, airway reactivity, the level of Th2 cytokines in lymph supernatant, IgE, airway inflammation, and goblet cell metaplasia were all significantly increased. The increases were suppressed by FPS-ZM1, JNJ-26482585, and romidepsin. The expression of HDAC1, RAGE, and p-AKT/t-AKT was also upregulated in TDI-induced asthmatic mice, and the expressions were attenuated by FPS-ZM1. Knockdown of RAGE attenuated the upregulation of HDAC1 and phospho-AKT (p-AKT) in 16HBE cells stimulated by TDI-HSA. Treatment with the AKT inhibitor MK2006 suppressed TDI-induced HDAC1 expression. ConclusionRAGE mediates airway inflammation in a TDI-induced murine asthma model, partly via the HDAC1 pathway.
