The study demonstrated that the OVA/CFA sensitization model successfully induced neutrophilic asthma and airway inflammation, while FIP-fve improved airway features and significantly reduced neutrophil infiltration.
Background: Asthma animal models provide valuable information about the pathogenesis and the treatment of asthma. An ovalbumin (OVA)/complete Freund's adjuvant (CFA)-sensitized model was developed to induce neutrophil-dominant asthma and to investigate whether fungal immunomodulatory peptide-fve (FIP-fve) could improve asthma features in the OVA/CFA-sensitized model. Methods: We used female BALB/c mice and sensitized them intraperitoneally with OVA/CFA on days 1, 2, and 3. On days 14, 17, 21, 24, and 27, they were challenged with intranasal OVA. The airway hyper-responsiveness (AHR) was detected by BUXCO, inflammatory cells were stained with Liu's stain, the cytokines were detected using ELISA, and the airway inflammation was analyzed with hematoxylin and eosin stain. Results: According to the results, OVA/CFA sensitization could induce AHR, high levels of IgE, and inflammatory cells especially neutrophils infiltration in the lung and airway inflammation. IL-4, IL-5, IL-6, IL-8, IL-10, IL-13, IL-17, IL-25, IL-33, and transforming growth factor-beta (TGF-beta) increased in the OVA/CFA-sensitized mice. OVA/CFA-sensitized mice treated with FIP-fve not only increased IL-12 and IFN-gamma but also decreased IL-4, IL-5, IL-6, IL-8, IL-13, IL-17, IL-25, IL-33, and TGF-beta in the bronchoalveolar lavage fluid. Moreover, FIP-fve significantly decreased neutrophil infiltration in the lung. Conclusion: The OVA/CFA model induced neutrophilic asthma successfully, and FIP-fve improved neutrophil-dominant asthma.
