摘要:

目的 探究呼吸道合胞病毒(RSV)诱导的骨髓间充质干细胞来源的外泌体(BMSCs-Exo-RSV)诱发的哮喘模型小鼠气道炎症相关指标在五虎汤干预作用下的影响。 方法 获取BMSCs-Exo-RSV,采用滴鼻方式进行干预造模,构建哮喘小鼠模型。选择60只SPF级雄性C57小鼠,随机分为空白组、模型组、利巴韦林干预组和五虎汤低、中、高剂量干预组,每组10只;以1日1次的频次分组干预与记录,连续2周。实验结束后,对比各组小鼠行为情况,通过DSI Buxco PFT肺功能检测系统检测各组小鼠肺功能残气量与肺总量比(RV/TLC),检测小鼠肺功能气流受限的程度;通过Masson染色法和苏木精-伊红染色法对比各组小鼠肺组织病理学变化;提取各组小鼠肺泡灌洗液,使用酶联免疫吸附法检测肺泡灌洗液中炎症因子γ干扰素(IFN-γ)、白细胞介素-12(IL-12)、白细胞介素-4(IL-4)、白细胞介素-6(IL-6)的含量;实时荧光定量聚合酶链式反应法检测miRNA-144的表达。 结果 与空白组相比,模型组小鼠出现呼吸增快、挠鼻、喷嚏多、体质量减轻等临床症状;肺功能RV/TLC升高,差异有统计学意义(P<0.01),提示气流受限;肺组织病理学切片提示炎症损伤加重;肺泡灌洗液中炎症因子IFN-γ、IL-12减少,IL-4、IL-6增高,差异有统计学意义(P<0.01),进一步提示气道炎症形成;miRNA-144表达上调,差异有统计学意义(P<0.01);与模型组相比,五虎汤低、中、高剂量干预组,利巴韦林干预组哮喘小鼠呼吸增快、挠鼻、喷嚏多、体质量减轻等临床症状均有改善,肺功能通气受限减轻,差异有统计学意义(P<0.01),肺组织炎症浸润改善,肺泡灌洗液中IFN-γ、IL-12增高,IL-4、IL-6下降,miRNA-144表达下降,差异有统计学意义(P<0.01)。 结论 五虎汤有效调节BMSCs-Exo-RSV诱发的哮喘模型小鼠免疫平衡,改善小鼠气道炎症反应,可能与其抑制miRNA-144上调有关。

Abstract:

Objective To investigate the effects of Wuhu decoction on airway inflammation-related indicators in asthmatic mice induced by respiratory syncytial virus (RSV)-primed bone marrow mesenchymal stem cell-derived exosomes(BMSCs-Exo-RSV). Methods The asthma mouse model was established by intranasal administration of BMSCs-Exo-RSV. Sixty SPF-grade male C57 mice were randomly divided into six groups(n=10 per group): control group, BMSCs-Exo-RSV model group, ribavirin intervention group, and low-, medium-, and high-dose Wuhu decoction intervention groups. Interventions were performed and recorded once daily for two weeks. After the experiment, the behaviors of the mice in each group were compared. Pulmonary function testing using the DSI Buxco PFT system was conducted to measure residual volume/total lung capacity ratio(RV/TLC) and airflow limitation of the pulmonary function of mice; histopathological changes of lung tissues were compared via Masson and HE staining;ELISA quantification of IFN-γ, IL-12, IL-4, and IL-6 levels in bronchoalveolar lavage fluid(BALF) was performed; qPCR was used to determine microRNA-144(miRNA-144) expression. Results Compared with the control group, BMSCs-Exo-RSV model mice exhibited clinical symptoms(tachypnea, nasal scratching, sneezing, weight loss), elevated RV/TLC(P<0.01) that indicated airflow limitation, aggravated inflammatory injury of lung tissues by pathological examination, decreased IFN-γ and IL-12(P<0.01) and increased IL-4 and IL-6(P<0.01) in BALF that further suggested formation of airway inflammation, and upregulated miRNA-144(P<0.01). Compared with model group, Wuhu decoction(all doses) and ribavirin groups showed improvement in clinical symptoms of tachypnea, nasal scratching, sneezing and weight loss, airflow limitation was reduced(P<0.01), pulmonary inflammation was improved, IFN-γ and IL-12(P<0.01) increased while IL-4 and IL-6 decreased(P<0.01) in BALF, and the expression of miRNA-144 decreased(P<0.01). Conclusion Wuhu decoction effectively modulates immune balance and alleviates airway inflammation in BMSCs-Exo-RSV-induced asthmatic mice, which may be related to its inhibition of miRNA-144 upregulation.
