Abstract

BACKGROUND

Cough variant asthma (CVA) is a disease with no definitive diagnosis or pathogenic causes, and still lacks effective and safe treatment. Wuhu decoction is a traditional Chinese medicine with potential effects against CVA, of which underlying mechanism remains elusive. The aim of this study is to explore the therapeutic potential of Wuhu decoction against CVA.

METHODS

The CVA mice model was established by ovalbumin (OVA) treatment. The airway hyperresponsiveness and remodeling were assessed. The pulmonary inflammatory injury was determined by counting of inflammatory cells and serum OVA-specific immunoglobulin E (IgE) in bronchoalveolar lavage fluid, as well as the amount of CD4, CD8 or CD25 T cells. The Th1/Th2 balance was evaluated by type specific cytokines. The level of antisense long non-coding RNA TRPM2 (lncTRPM2-AS) and its downstream targets were determined by mRNA and protein detection, respectively.

RESULTS

Wuhu decoction could improve airway hyperresponsiveness and remodeling in OVA-induced asthmatic mice model by regulating Th1/Th2 balance and affecting pulmonary inflammatory injury. On the molecular level, Wuhu decoction significantly inhibited the expression of lncTRPM2-AS, which was found to be a critical modulator of Th1/Th2 balance. Meanwhile, overexpression of lncTRPM2-AS could abolish Wuhu decoction-mediated protection effects on OVA-induced asthmatic mice model.

CONCLUSIONS

This study discovered the protective function of Wuhu decoction against CVA and illustrated its molecular mechanism, highlighting the therapeutic application of Wuhu decoction for asthma treatment.

摘要

背景

咳嗽变异性哮喘(CVA)是一种诊断不明确且病因不明的疾病,仍然缺乏有效且安全的治疗方法。五胡汤是一种对CVA可能有潜在疗效的中药,但其潜在机制仍不清楚。本研究的目的是探讨五胡汤对CVA的治疗潜力。

方法

通过卵清蛋白(OVA)处理建立CVA小鼠模型。评估气道高反应性和重塑情况。通过计数支气管肺泡灌洗液中的炎性细胞和血清OVA特异性免疫球蛋白E(IgE)以及CD4、CD8或CD25 T细胞的数量来确定肺部炎性损伤。通过特定类型的细胞因子评估Th1/Th2平衡。分别通过mRNA和蛋白质检测来确定反义长链非编码RNA TRPM2(lncTRPM2-AS)及其下游靶点的水平。

结果

五胡汤可通过调节Th1/Th2平衡并影响肺部炎性损伤来改善OVA诱导的哮喘小鼠模型中的气道高反应性和重塑。在分子水平上,五胡汤显著抑制lncTRPM2-AS的表达,发现其是Th1/Th2平衡的关键调节因子。同时,lncTRPM2-AS的过表达可消除五胡汤对OVA诱导的哮喘小鼠模型的保护作用。

结论

本研究发现了五胡汤对CVA的保护作用并阐明了其分子机制,突出了五胡汤在哮喘治疗中的治疗应用。
