Introduction Parasites and parasite-derived extracellular vesicles (EVs) microRNAs (miRNAs) can protect against inflammatory diseases, such as asthma. M2a macrophages facilitate the development of allergic miR-10a-5p is closely associated with asthma, emu-miR-10a-5p (encapsulated in Echinococcus multilocularis EVs), shares seed-site sequences mature human mouse miRNAs. Methods We purified EVs by centrifugation, characterized via nanoparticle tracking analysis (NTA) transmission electron microscopy (TEM). used MH-S cells to construct polarization model. The gene expression changes after transfect mimics was analyzed through transcriptome sequencing. established a model ovalbumin (OVA)-induced Hematoxylin eosin (H&E), Masson’s trichrome, periodic acid–Schiff (PAS) staining were detect airway inflammation lung tissues. RT-qPCR, flow cytometry Western Blot assays performed validate related genes proteins. Results Here, we observed that E. -derived their encapsulated transcripts inhibited macrophage polarization. also found targeted leukemia inhibitory factor (LIF) mRNA downstream Janus kinase 1 (JAK1)–signal transducer activator transcription 3 (STAT3)-signaling pathway. asthma alleviated pulmonary mice while inhibiting accumulation macrophages. intervention LIF JAK1–STAT3 signaling lungs Discussion These findings suggest might regulate pathway targeting binding cross-species manner, thereby alleviating enhance current understanding mechanisms underlying immune regulation during infection maintenance stability.
