Aeromonas salmonicida (A. salmonicida) is a pathogenic bacterium that causes serious problems in the global Atlantic salmon aquaculture industry. In this study, we comprehensively analyzed the profiles of lncRNAs, miRNAs and mRNAs in gills of Atlantic salmon at high-dose A. salmonicida infection (3.06 × 108 CFU/mL), low-dose A. salmonicida infection (3.06 × 105 CFU/mL), and a PBS (100 μL) control. We identified 65 differentially expressed lncRNAs, 41 miRNAs, and 512 mRNAs between the control group and infection groups. Functional analysis showed that these genes were significantly enriched in the p53 signaling pathway, Wnt signaling pathway, mTOR signaling pathway, JAK-STAT signaling pathway, and Toll-like receptor signaling pathway. In addition, we predicted key genes in immune-related pathways and constructed a lncRNA-miRNA-mRNA network based on whole transcriptomic analysis. We further predicted three lncRNA-miRNA-mRNA axes as potential novel biomarkers in regulating the immune response of Atlantic salmon against A. salmonicida infection. • MiRNAs, LncRNAs and mRNAs regulate immune response in Atlantic salmon challenged by Aeromonas salmonicida. • MiRNAs target genes in immune-related pathways could have major functions. • A ceRNA network was constructed to reveal the function of lncRNA-miRNA-mRNA interaction. • Three lncRNA-miRNA-mRNA axis as novel potential biomarkers regulate immune response of Atlantic salmon against A. salmonicida infection.
