摘要Aeromonas salmonicida is a major etiologic agent which induces furunculosis and is globally harmful in salmonid and turbot cultures, especially in Atlantic salmon (Salmo salar) farming. In order to improve knowledge of its poorly understood pathogenesis, we utilized high-throughput proteomics to display differentially expressed proteins in the kidney of Atlantic salmon challenged with high and low infection dose of A. salmonicida at 7 and 14 days. In quantitative proteomic assays, isobaric tags for relative and absolute quantitation (iTRAQ) combined with 2D LC-MS/MS is emerging as a powerful methodology in the search for disease-specific targets and biomarkers. In this study, 4009 distinct proteins (unused >= 1.3, which is a confidence >= 95%) were identified in three two-dimensional LC/MS/MS analyses. Then we chose 140 proteins (fold change ratio >= 1.5 and P < 0.01) combined with protein protein interaction analysis to ultimately obtain 39 proteins in network which could be considered as potential biomarkers for Atlantic salmon immune responses. Nine significant differentially expressed proteins were consistent with those at the proteomic level used to validate genes at the transcriptomic level by qPCR. Collectively, these data was first reported using an iTRAQ approach to provide additional elements for consideration in the pathophysiology of A. salmonicida and pave the way to resolve the influence of this disease in Atlantic salmon.
