Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial lung condition with unknown etiology and high mortality. Chinese herbal medicine has been used for more than a thousand years to treat various lung diseases.The current study aimed to examine whether Chinese herbal Maxing Huoqiao Decoction (MXHQD) exerts therapeutic effects on IPF and to further uncover its underlying molecular mechanisms.Mouse model of acute lung injury (ALI) or IPF was induced by intratracheal instillation of LPS or bleomycin, respectively. ALI mice were treated with MXHQD for 7 days, and lung tissues were taken for test after modeling 24 h. IPF mice were gavaged for 21 days after modeling. Lung tissues were subjected to whole transcriptome detection, and the differential RNAs were experimentally verified.The results showed that MXHQD alleviated the computed tomography (CT) and the pathological degree changes in mice with IPF, improved changes in the expression of fibrosis related genes and reduced the hydroxyproline expression in IPF mice. MXHQD also decreased the cell numbers in bronchoalveolar lavage fluids, and the expression levels of the inflammatory factors in the ALI mice lung tissues were significantly inhibited. By applying whole transcriptome analysis, results showed that MXHQD acted on 40 mRNAs, 15 miRNAs, 25 novel lncRNAs and 17 circRNAs to resist pulmonary fibrosis. The competing endogenous RNA (ceRNA) network diagram showed that the multiple components of MXHQD against fibrosis through a network of multiple targets. The differential mRNAs were mainly related to the innate immune response and the defense response to virus. Then the expression of mRNAs in the differential mRNA-miRNA-differential circRNA network in the lung tissue of IPF was verified. The expression of ZBP1 and ISG15 related to immune system and anti virus was verified at both gene and protein expressions. MXHQD could significantly inhibit the elevation of ZBP1 and ISG15 factors induced by the fibrosis model.Overall, our findings provide compelling evidence that MXHQD can alleviate IPF by modulating innate immunity. This is the first study to reveal the molecular mechanism underlying the multi-components, multi-channels and multi-targets anti-IPF immune injury of MXHQD, and supports its potential clinical application for IPF.Copyright © 2023 The Author(s).
