英文摘要Sea urchins are a popular model species for studying invertebrate diseases. The immune regulatory mechanisms of the sea urchin Mesocentrotus nudus during pathogenic infection are currently unknown. This study aimed to reveal the potential molecular mechanisms of M. nudus during resistance to Vibrio coralliilyticus infection by integrative transcriptomic and proteomic analyses. Here, we identified a total of 135,868 unigenes and 4,351 proteins in the four infection periods of 0 h, 20 h, 60 h and 100 h in M. nudus. In the I20, I60 and I100 infection comparison groups, 10,861, 15,201 and 8,809 differentially expressed genes (DEGs) and 2,188, 2,386 and 2,516 differentially expressed proteins (DEPs) were identified, respectively. We performed an integrated comparative analysis of the transcriptome and proteome throughout the infection phase and found very a low correlation between transcriptome and proteome changes. KEGG pathway analysis revealed that most upregulated DEGs and DEPs were involved in immune strategies. Notably, "lysosome" and "phagosome" activated throughout the infection process, could be considered the two most important enrichment pathways at the mRNA and protein levels. The significant increase in phagocytosis of infected M. nudus coelomocytes further demonstrated that the lysosome-phagosome pathway played an important immunological role in M. nudus resistance to pathogenic infection. Key gene expression profiles and protein-protein interaction analysis revealed that cathepsin family and V-ATPase family genes might be key bridges in the lysosome-phagosome pathway. In addition, the expression patterns of key immune genes were verified using qRT-PCR, and the different expression trends of candidate genes reflected, to some extent, the regulatory mechanism of immune homeostasis mediated by the lysosome-phagosome pathway in M. nudus against pathogenic infection. This work will provide new insights into the immune regulatory mechanisms of sea urchins under pathogenic stress and help identify key potential genes/ proteins for sea urchin immune responses.
