摘要: Klebsiella variicola is an emerging pathogen that has become a threat to human and animal health. There is evidence that long noncoding RNAs (lncRNAs) are involved in a host cell's response to microbial infections. However, no study has defined the link between K. variicola pathogenesis and lncRNAs until now. We used RNA sequencing to comprehensively analyze the lncRNAs and mRNAs in the chicken spleen after K. variicola infection. In total, we identified 2896 differentially expressed mRNAs and 578 differentially expressed lncRNAs. To examine the potential functions of these lncRNAs, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes signaling pathway enrichment analyses were performed on the target mRNAs of these differently expressed lncRNAs. The results suggested that lncRNAs play essential roles in modulating mRNA expression and triggering downstream immune signaling pathways to regulate the immune response in the chicken spleen. Using previous microRNA sequencing data, we constructed lncRNA-miRNA-mRNA regulatory networks to clarify the regulatory mechanisms in the chicken immune system. Several potential regulatory pairs related to K. variicola infection were found, involving XR_001467769.2, TCONS_00018386, gga-miR-132a-3p, gga-miR-132b-5p, gga-miR-2954, and novel62_mature. In conclusion, our findings make a significant contribution towards understanding the role of lncRNA in chicken spleen cells during K. variicola infection, thereby establishing a solid foundation for future research in this area.
