Common carp (Cyprinus carpio) CD81 promoting CyHV-3 virus replication via regulating autophagy and RLRs-interferon signaling pathway. FISH & SHELLFISH IMMUNOLOGY 2023; 143:109181. [PMID: 37871756 DOI: 10.1016/j.fsi.2023.109181] [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: 08/31/2023] [Revised: 10/18/2023] [Accepted: 10/19/2023] [Indexed: 10/25/2023]
Abstract
Cyprinid herpesvirus type 3 (CyHV-3), also called Koi herpesvirus (KHV), which leads to mass cyprinid mortality and enormous economic losses. To establish an infection, CyHV-3 needs to counteract host antiviral responses. CD81 belongs to the evolutionary conserved tetraspanin family of proteins. Several studies have shown that different members of the tetraspanin superfamily modulates different virus infectious processes. Here we aimed at analysing the role of CD81 in CyHV-3 infection. In this study, we cloned and characterized the CD81 of Common Carp, the open reading frame of CcCD81 gene was 702 bp, which encoded 234 amino acids with four transmembrane domains (TM1 to TM4), a small extracellular loop (SEL), and a large extracellular loop (LEL). Tissue distribution analysis showed that CcCD81 was widely expressed in all the tested tissues with the highest expression in head kidney, followed by a high expression in brain. Subsequently, expression levels of CcCD81 were significantly increased in CCB cells within the first 3h after infection, meanwhile, the expression of viral gene VP136 was reduced after CcCD81 knockdown in CCB cells post CyHV-3 infection. Furthermore, CcCD81 knockdown can significantly reduce the autophagy process and increase the promoter activity of ISRE and IFN-1 in the CCB cells after viral infection, as well as other genes involved in the IFN signaling pathway, including RIG-1、MDA5、MAVS、TBK1 and IRF3. Taking the data together, we revealed that CcCD81 mediates autophagy and blocks RIG-1-mediated antiviral signaling and negatively regulates the promoter activity of type I interferon (IFN) promoting virus replication. These results reveal a new link between autophagy and four-transmembrane-domain protein superfamily and contribute to elucidate the mechanism of CyHV-3 infection.

Abstract
Tetraspanins are a family of membrane proteins, which play important roles in many aspects of cell biology and physiology via binding other tetraspanins or proteins. In this study, we identified 251 putative tetraspanin genes in 6 teleost fishes. Conserved gene organization and motif distribution suggested their functional relevance existing in each group. Synteny analyses implied conserved and dynamic evolution characteristics of this gene family in several vertebrates. We also found that some recombination events have accelerated the evolution of this gene family. Moreover, a few positive selection sites were identified. Expression patterns of some tetraspanins were further studied under organophosphorus stress using transcriptome sequencing. Functional network analyses identified some interacting genes that exhibited 174 interactions, which reflected the diversity of tetraspanin binding proteins. The results will provide a foundation for the further functional investigation of the tetraspanin genes in fishes.

Abstract
Tetraspanins, a large cell surface protein superfamily characterized by having four transmembrane domains, play many critical roles in physiological and pathological processes. In this study, we report the identification, characterization and phylogenetic analysis of the channel catfish tetraspanin 3 and tetraspanin 7 (CD231) transcripts. The full-length nucleotide sequences of tetraspanin 3 and tetraspanin 7 cDNA have 1,453 and 1,842 base pairs, respectively. Analysis of the nucleotide sequences reveals that each has one open reading frame (ORF). The ORF of tetraspanin 3 appears to encode 241 amino acids with calculated molecular mass of 26.8 kDa, while the ORF of tetraspanin 7 potentially encodes 251 amino acids with calculated molecular mass of 27.9 kDa. By comparison with the human counterparts, the channel catfish tetraspanin 3 and tetraspanin 7 peptides have four transmembrane domains, three intracellular domains and two (small and large) extracellular domains. In addition, several characteristic features critical for structure and functions in mammalian tetraspanins are also conserved in channel catfish tetraspanin 3 and tetraspanin 7. The transcripts were detected by RT-PCR in restrictive organs. These results with those from our previous studies on other channel catfish tetraspanins provide important information for further investigating the roles of various tetraspanins in channel catfish infection with microorganisms.

Abstract
Protein arginine methylation, catalyzed by protein arginine methyltransferases (PRMT), has recently emerged as an important modification in the regulation of gene expression. In this communication, we identified and characterized the channel catfish orthologs to human PRMT 1, 3, 4 and 5, and PRMT4 like. Each PRMT nucleic acid sequence has an open reading frame (ORF) and 3'-untranslated regions. Each ORF appears to encode 361, 587 and 458 amino acid residues for PRMT1, PRMT4 and variant, respectively. The partial ORF of PRMT3 and PRMT5 encode 292 and 563 amino acids, respectively. By comparison with the human counterparts, each channel catfish PRMT also has conserved domains. For expression profile, the channel catfish PRMT1 transcript was detected by RT-PCR in spleens, anterior kidneys, livers, intestines, skin and gills of fish examined. Except in liver, the PRMT3 transcript was detected in all catfish tissues examined. However, the PRMT4 cDNA was detected in livers from all three catfish and gills from two fish, but not other tissues. This information will enable us to further elucidate PRMT functions in channel catfish.

Abstract
Chemokine receptor CXCR4, a member of the G protein-coupled receptor superfamily, binds selectively CXCL12. This protein plays many important roles in immunological as well as pathophysiological functions. In this study, we identified and characterized the channel catfish CXCR4 transcript. The full-length nucleic acid sequence of channel catfish CXCR4 cDNA comprised of 1994 nucleotides, including an open reading frame, which appears to encode a putative peptide of 357 amino acid residues with a calculated molecular mass of 40.1kDa. By comparison with the human counterpart, the channel catfish CXCR4 peptide can be divided into domains, including seven transmembrane domains, four cytoplasmic domains, and four extracellular domains. The CXCR4 transcript was detected in spleen, anterior kidney, liver, intestine, skin and gill of all catfish examined in this study. Because four CXCL of channel catfish have been identified, the result provides valuable information for further exploring the channel catfish chemokine signalling pathways and their roles in immune responses to infection.

Abstract
CD63, known as lysosome associated membrane protein 3 (LAMP-3), is a member of the tetraspanin integral membrane protein family. This protein plays many important roles in immuno-physiological functions. In this communication, we report the identification, characterization, and expression analysis of the channel catfish CD63 transcript. The complete nucleic acid sequence of channel catfish CD63 cDNA was comprised of 1159 nucleotides, including an open reading frame, which appears to encode a putative peptide of 237-amino-acid residues. Like other tetraspanin proteins, the channel catfish CD63 peptide can be divided into domains, including four transmembrane domains, three intracellular domains, and one of each small and large extracellular loops. The channel catfish CD63 peptide shares 52-55% identity among fish counterparts, but only 43-46% identity among mammalian counterparts. The characteristic Cys-Cys-Gly motif and four Cys residues in the large extracellular loop were conserved. The channel catfish CD63 transcript was detected by RT-PCR in spleen, anterior kidney, liver, intestine, skin and gill. This result provides important information for further elucidating CD63 functions in channel catfish.

Abstract
CD156a, also known as a disintegrin and metalloprotease domain 8 (ADAM-8), is a type 1 transmembrane glycoprotein of the ADAM family. This protein plays important roles in immune and other physiological functions. In this communication, the channel catfish CD156a cDNA was characterized and its expression in various tissues was determined. The full-length of channel catfish CD156a cDNA had 3035 nucleotides, including an open reading frame which appears to encode an 850 amino acid peptide with a calculated molecular mass of 94.6kDa. The peptide had three potential N-glycosylation sites. By comparison with other species, the degree of homology of the CD156a amino acid sequences ranged from 31.6% (vs. chicken CD156a) to 59.5% (vs. zebrafish CD156a). The channel catfish CD156a peptide could be structurally divided into nine domains. Several canonical features for CD156a functions were conserved in channel catfish. The CD156a transcript was detected by two-step RT-PCR in anterior kidney and gill, suggesting that CD156a may be involved in the innate immune response in channel catfish. Reagents for further elucidating the immune functions of channel catfish CD156a are under development.
