Comparative transcriptional analysis between virulent isolate HN1307 and avirulent isolate GD1108 of grass carp reovirus genotype II. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 147:104893. [PMID: 37451563 DOI: 10.1016/j.dci.2023.104893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 07/10/2023] [Accepted: 07/11/2023] [Indexed: 07/18/2023]
Abstract
As a widespread epidemic virus, genotype II of the grass carp reovirus poses a significant threat to the grass carp farming industry in China. Different genotype II isolates cause different degrees of virulence, although the underlying pathogenic mechanisms remain largely unknown. In this work, infections of grass carp with the virulent isolate grass carp reovirus (GCRV)-HN1307 and the avirulent isolate GCRV-GD1108 were performed to reveal a possible mutual transcriptional discrepancy. More differentially expressed genes (DEGs) were identified in the HN1307-infected group, which defined a grossly similar gene ontology (GO) pattern and different pathway landscape as the GD1108-infected group. Gene set enrichment analysis revealed that pathways related to innate immunity and metabolism were reciprocally activated and suppressed, respectively, following infection withHN1307, compared with GD1108. The trend analysis further indicated that immune-related pathways were involved in one of the four statistically significant profiles. Network analysis of transcription factor-gene interactions and protein-protein interactions on the immune-related profile suggested that among the core transcriptional factors (TFs) (UBTF, HCFC1, MAZ, MAX, and NRF1) and the hub proteins (Tlr3, Tlr7, Tlr9, Irf3, and Irf7), the latter were highly enriched in the toll-like receptor signaling pathway. Real-time quantitative PCR performed on the selected mRNAs validated the relative expression. This work will provide insights into the distinct transcriptional signatures from avirulent and virulent isolates of GCRV, which may contribute to the development of products for prevention.

Abstract
Grass carp reovirus genotype Ⅱ (GCRV Ⅱ) causes hemorrhagic disease in a variety fish, seriously affecting the aquaculture industry in China. However, the pathogenesis of GCRV Ⅱ is unclear. Rare minnow is an ideal model organism to study the pathogenesis of GCRV Ⅱ. Herein, we applied liquid chromatography-tandem mass spectrometry metabolomics to investigate metabolic responses in the spleen and hepatopancreas of rare minnow injected with virulent GCRV Ⅱ isolate DY197 and attenuated isolate QJ205. Results indicated that marked metabolic changes were identified in both the spleen and hepatopancreas after GCRV Ⅱ infection, and the virulent DY197 strain induced more significantly different metabolites (SDMs) than the attenuated QJ205 strain. Moreover, most SDMs were downregulated in the spleen and tend to be upregulated in hepatopancreas. The Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that tissue-specific metabolic responses were identified after viruses infection, and the virulent DY197 strain induced more SDMs involved in amino acid metabolism in the spleen, especially the tryptophan metabolism, cysteine and methionine metabolism, which were essential for immune regulation in host; Meanwhile, nucleotide metabolism, protein synthesis and metabolism related pathways were enriched in the hepatopancreas by both virulent and attenuated strains. Our findings revealed the large scale metabolic alterations in rare minnow in response to attenuated and virulent GCRV Ⅱ infection, which will lead to a better understanding of the pathogenesis of viruses and host-pathogens interactions.

Abstract
Major histocompatibility complex class Ⅰ (MHC Ⅰ) molecules play a vital role in adaptive immune systems in vertebrates by presenting antigens to effector T cells. Understanding the expression profiling of MHC Ⅰ molecules in fish is essential for improving our knowledge of the relationship between microbial infection and adaptive immunity. In this study, we conducted a comprehensive analysis of MHC Ⅰ gene characteristics in Carassius auratus, an important freshwater aquaculture fish in China that is susceptible to Cyprinid herpesvirus 2 (CyHV-2) infection. We identified approximately 20 MHC Ⅰ genes discussed, including U, Z, and L lineage genes. However, only U and Z lineage proteins were identified in the kidney of Carassius auratus using high pH reversed-phase chromatography and mass spectrometry. The L lineage proteins were either not expressed or present at an extremely low level in the kidneys of Carassius auratus. We also used targeted proteomics to analyze changes in protein MHC Ⅰ molecules abundance in healthy and CyHV-2-infected Carassius auratus. We observed that five MHC Ⅰ molecules were upregulated, and Caau-UFA was downregulated in the diseased group. This study is the first to reveal the expression of MHC Ⅰ molecules at a large scale in Cyprinids, which enhances our understanding of fish adaptive immune systems.
