摘要： Vibrio parahaemolyticus is the main pathogen responsible for acute hepatopancreatic necrosis disease in crustaceans. To further understand the immune regulatory mechanisms against V. parahaemolyticus in crustaceans, we employed multi-omics to elucidate the competitive endogenous RNAs (ceRNAs) regulatory network in V. parahaemolyticus-infected Portunus trituberculatus. A total of 8,093 long non-coding RNAs (lncRNAs) in the hepatopancreas of P. trituberculatus were identified, among which 739 were differentially expressed after infection. The target genes of the differentially expressed lncRNAs were enriched in immune-related pathways, including NOD-like receptor signaling and TNF signaling pathways. Further investigation demonstrated that lncRNAs may modulate immune responses by interacting with microRNAs and mRNAs to form complex ceRNA networks. Of particular interest, lncRNA MSTRG.2618.5 was identified acts as a molecular sponge for novel0095, thereby enhancing the expression of interferon regulatory factor 2 gene. The present study provides novel insights into the immune regulatory mechanisms of P. trituberculatus, highlighting the significant role of lncRNAs in crustacean immunity. The findings contribute to our understanding of disease resistance in aquatic animals and offer potential molecular targets for the selective breeding of disease-resistant strains in aquaculture.
