Renifolin F是一种从中国少数民族传统药物天门冬中分离得到的戊基化查尔酮,用于治疗呼吸系统疾病和哮喘。在原药用植物作用的基础上,我们以卵白蛋白(OVA)为诱导剂,建立小鼠体内变应性哮喘模型,评价肾ifolin F的治疗作用。本研究采用OVA致敏和激发小鼠,建立变应性哮喘模型,评价肾ifolin F对变应性哮喘的作用。观察气道对甲胆碱的高反应性(AHR)、细胞因子水平、ILC2s数量及mircoRNA-155表达。我们发现肾ifolin F通过抑制肺中ILC2s的调节,从而降低上游炎症因子IL-25、IL-33和TSLP,从而减轻ova诱导的哮喘小鼠模型AHR和气道炎症;ILC2s下游炎性因子IL-4、IL-5、IL-9、IL-13;共刺激因子IL-2和IL-7;以及肺组织中microRNA-155的表达。研究结果提示肾ifolin F对ova诱导的气道炎症具有治疗潜力。
Renifolin F is a prenylated chalcone isolated from Shuteria involucrata, a traditional minority ethnic medicine used to treat the respiratory diseases and asthma. Based on the effects of the original medicine plant, we established an in vivo mouse model of allergic asthma using ovalbumin (OVA) as an inducer to evaluate the therapeutic effects of Renifolin F. In the research, mice were sensitized and challenged with OVA to establish an allergic asthma model to evaluate the effects of Renifolin F on allergic asthma. The airway hyper-reactivity (AHR) to methacholine, cytokine levels, ILC2s quantity and mircoRNA-155 expression were assessed. We discovered that Renifolin F attenuated AHR and airway inflammation in the OVA-induced asthmatic mouse model by inhibiting the regulation of ILC2s in the lung, thereby, reducing the upstream inflammatory cytokines IL-25, IL-33 and TSLP; the downstream inflammatory cytokines IL-4, IL-5, IL-9 and IL-13 of ILC2s; and the co-stimulatory factors IL-2 and IL-7; as well as the expression of microRNA-155 in the lung. The findings suggest a therapeutic potential of Renifolin F on OVA-induced airway inflammation.
