摘要： Infection of Taenia pisiformis cysticercus is very frequently found in lagomorphs and causes serious economic losses to rabbit breeding industry. T. pisiformis cysticercus has evolved numerous strategies to manipulate their hosts. The release of exosomes is of importance in the interaction between host and parasite. However, the mechanism by which T. pisiformis cysticercus evades the host immune system for long-term survival within the host remains unclear. Using small RNA sequencing and TMT labelling proteomic, we profiled the expression patterns of miRNAs and proteins in rabbit peritoneal macrophages treated with T. pisiformis cysticercus exo-somes. Seven differentially expressed (DE)-miRNAs and six DE-proteins were randomly selected to validate the accuracy of the sequencing data by qRT-PCR or western blot. Functions of DE-miRNAs and proteins were analyzed using public data bases. And DE-miRNAs-DE-proteins correlation network were established. CCK-8 assay was used to evaluate the effect of exosomes on macrophages proliferation. Cell cycle of macrophages, isolated from T. pisiformis-infected rabbits, was determined using flow cytometry. A total of 21 miRNAs were significantly differentially expressed, including three worm-derived miRNAs. The expressions of miRNAs and proteins were consistent with the sequencing results. DE-miRNAs targets were related to cell proliferation and apoptosis. Exosomes treatment resulted in a decrease of macrophages proliferation. In vivo, T. pisiformis cysti-cercus significantly induced S phase cell arrest. Moreover, DE-proteins were related to production of interferon -gamma and interleukin-12, and immunoregulation. Correlation network analysis revealed a negative correlation relationship between DE-miRNAs and DE-proteins. Among them, novel334 and tpi-let-7-5p have potential reg-ulatory effects on IL1 & beta; and NF & kappa;B2 respectively, which imply that novel334-IL1 & beta;/tpi-let-7-5p-NF & kappa;B2 axis may be an important way that T. pisiformis cysticercus modulates host immune response through exosomes. Further understanding of these potential regulatory mechanisms will contribute to clarify the mechanism of escape mediated by T. pisiformis exosomes.
