摘要： Reticuloendotheliosis virus (REV) is an important representative avian retrovirus. To improve our understanding of the host cellular responses to virus infection and the pathogenesis of REV infection, we applied isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with multidimensional liquid chromatography-tandem mass spectrometry to detect changes in protein levels in chicken embryo fibroblast cells (CEFs) that were infected with REV or mock infected. In total, 605 cellular proteins were differentially expressed, among which 196, 345, and 286 were differentially expressed in REV-infected CEFs at 1, 3, and 5 days postinfection, respectively. Gene Ontology analysis indicated that the biological processes of the differentially expressed proteins were primarily related to cellular processes, metabolic processes, biological regulation, response to stimulus, and immune system processes and that the molecular functions in which the differentially expressed proteins were mainly involved were binding, catalytic activity, and enzyme regulator activity. Pathway analysis showed that a total of 143, 167, and 179 pathways, including protein digestion and absorption, focal adhesion, ECM-receptor interaction, cytokine-cytokine receptor interaction, Toll-like receptors, and JAK-STAT signaling, were enriched in REV-infected CEFs at 1, 3, and 5 days postinfection, respectively. In conclusion, this study is the first to analyze the protein profile of REV-infected CEFs using an iTRAQ approach. The results of this study provide valuable information for better understanding the host response to REV infection.
