Animals (Basel) 2023; 13:3157. [PMID: 37835763 PMCID: PMC10571807 DOI: 10.3390/ani13193157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 09/22/2023] [Accepted: 10/06/2023] [Indexed: 10/15/2023] Open
Abstract
IFNAR1, one of the type I IFN receptors, is crucial to mammalian host defense against viral invasion. However, largely unknown is the immunological role of the fish teleost protein IFNAR1, also known as CRFB5. We have successfully cloned the whole cDNA of the Japanese eel's (Anguilla japonica) CRFB5a homolog, AjCRFB5a. The two fibronectin-3 domains and the transmembrane region (238-260 aa) of AjCRFB5a are normally present, and it shares a three-dimensional structure with zebrafish, Asian arowana, and humans. According to expression analyses, AjCRFB5a is highly expressed in all tissues found, particularly the liver and intestine. In vivo, Aeromonas hydrophila, LPS, and the viral mimic poly I:C all dramatically increased AjCRFB5a expression in the liver. Japanese eel liver cells were reported to express AjCRFB5a more strongly in vitro after being exposed to Aeromonas hydrophila or being stimulated with poly I: C. The membranes of Japanese eel liver cells contained EGFP-AjCRFB5a proteins, some of which were condensed, according to the results of fluorescence microscopy. Luciferase reporter assays showed that AjCRFB5a overexpression strongly increased the expression of immune-related genes in Japanese eel liver cells, such as IFN1, IFN2, IFN3, IFN4, IRF3, IRF5, and IRF7 of the type I IFN signaling pathway, as well as one of the essential antimicrobial peptides LEAP2, in addition to significantly inducing human IFN-promoter activities in HEK293 cells. Additionally, RNA interference (RNAi) data demonstrated that knocking down AjCRFB5a caused all eight of those genes to drastically lower their expression in Japanese eel liver cells, as well as to variable degrees in the kidney, spleen, liver, and intestine. Our findings together showed that AjCRFB5a participates in the host immune response to bacterial infection by inducing antimicrobial peptides mediated by LEAP2 and favorably modulates host antiviral immune responses by activating IRF3 and IRF7-driven type I IFN signaling pathways.

Abstract
The class II cytokine receptor family members are receptors of class 2 helical cytokines in mammals, and are named cytokine receptor family B (CRFB) in fish. In zebrafish, sixteen members, including CRFB1, CRFB2 and CRFB4-17 were reported. With the availability of genome sequence, a total of nineteen CRFBs was identified in the blunt snout bream (Megalobrama amblycephala), including CRFB1, CRFB2, CRFB4-17 with the presence of three CRFB9 isoforms, and two CRFB14 isoforms. These CRFB molecules contain well conserved features, such as fibronectin type III (FNIII) domain, transmembrane and intracellular domains as other class II cytokine receptors, and are phylogenetically grouped into thirteen clades with their homologues from other species of fish. The CRFB genes were constitutively expressed in organs/tissues examined in the fish. The finding of more CRFB members in the bream may provide clues to understand possible receptor-ligand interaction and their diversity from an evolutionary point of view.

Abstract
The interferon receptor system in teleost fish is more complex than that in mammals. In the present study, we identified 13 cytokine receptor genes (10 interferon receptor genes and 3 IL10R2-like genes) from Chinese sturgeon (Acipenser sinensis) using RNA-sequencing. Sequence analysis indicated that these receptors had conserved domains, including signal peptides, FNⅢ, and transmembrane domains. Phylogenetic analysis suggested that they belonged to the cytokine receptor family. In the present study, we named them IFNAR1-like (CRFB5a, CRFB5b), IFNAR2-like (CRFB3a, CRFB3b), IFNGR1-like (IFNGR1), IFNGR2-like (CRFB6a, CRFB6b/IFNGR2-1, CRFB6c/IFNGR2-2, CRFB6d/IFNGR2-3, CRFB6e/IFNGR2-4) and IL10R2-like (CRFB4a, CRFB4b, CRFB4c), respectively. Constitutive expression analysis revealed that these receptor genes had potential functions in immune and non-immune tissue compartments. After stimulating with Poly (I:C), the expression fold changes of CRFB3a, CRFB4a, CRFB4b, CRFB5b, and CRFB6e/IFNGR2-4 in Chinese sturgeon were higher than those of other receptor genes, which revealed that these five genes had important functions in the immune process to resist virus invasion in the host. After stimulating with IFN gamma, the expression fold changes of CRFB3a, CRFB4a, and CRFB6b/IFNGR2-1 were higher than those other receptor genes. Based on other teleost fish interferon receptor models, we speculated that IFNAR1-like (CRFB5a, CRFB5b) and IFNAR2-like (CRFB3a, CRFB3b), comprised Chinese sturgeon type Ⅰ IFN receptors; and IFNGR1-like (IFNGR1) and IFNGR2-like (CRFB6/IFNGR2) comprised Chinese sturgeon type Ⅱ IFN receptors.

Abstract
Interferons (IFNs) are proteins of vital importance in the body's immune response. They are formed in different types of cells and have been found in fish, amphibians, reptiles and mammals. Two types of IFN have been found in ray-finned fish (Superclass: Osteichthyes, Class: Actinopterygii) so far, i.e. IFN type I (IFN I) and IFN type II (IFN II), while the presence of IFN type III (IFN III), which is found in phylogenetically older cartilaginous fishes, was not confirmed in this taxonomic group of vertebrates. Currently, type I IFN in Actinopterygii is divided into three groups, I, II and III, within which there are subgroups. These cytokines in these animals show primarily antiviral activity through the use of a signalling pathway JAK-STAT (Janus kinases - Signal transducer and activator of transcription) and the ability to induce ISG (IFN-stimulated genes) expression, which contain ISRE complexes (IFN-stimulated response elements). On the other hand, in Perciformes and Cyprinidae, it was found that type I/I interferons also participate in the antimicrobial response, inter alia, by inducing the expression of the inducible nitric oxide synthase (iNOS) and influencing the production of reactive oxygen species (ROS) in cells carrying out the phagocytosis process.

Identification and characterization of tilapia CRFB1, CRFB2 and CRFB5 reveals preferential receptor usage of three IFN subtypes in perciform fishes. FISH & SHELLFISH IMMUNOLOGY 2020; 107:194-201. [PMID: 33011433 DOI: 10.1016/j.fsi.2020.10.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 09/26/2020] [Accepted: 10/01/2020] [Indexed: 06/11/2023]
Abstract
Type I interferons are a subset of cytokines playing central roles in host antiviral defense, and their effects depend on the interaction with the heterodimeric receptor complex. Surprisingly, two pairs of the receptor subunits, CRFB1 and CRFB5, and CRFB2 and CRFB5, have been identified in fish, but the studies about preferential receptor usage of different fish IFN subtypes are rather limited. In this study, the three receptor chains of type I IFNs named as On-CRFB1, On-CRFB2 and On-CRFB5 were identified in Nile tilapia, Oreochromis niloticus. These three genes were constitutively expressed in all tissues examined, with the highest expression level observed in muscle and liver, and were rapidly induced in liver following the stimulation of poly(I:C). Interestingly, it is possible that all three subtypes of tilapia IFNs are able to signal through two pairs of the receptor subunits, On-CRFB1 and On-CRFB5, and On-CRFB2 and On-CRFB5. More importantly, tilapia group I IFNs (On-IFNd and On-IFNh) preferentially signal through a receptor complex composed of On-CRFB1 and On-CRFB5, and group II IFNs (On-IFNc) preferentially signal through a receptor complex comprised of On-CRFB2 and On-CRFB5. The present study thus provides new insights into the receptor usage of group I and group II IFNs in fish.

Abstract
Grouper is known as a highly economical teleost species in the Asian aquaculture industry; however, intensive culture activities easily cause disease outbreak, especially viral disease. For the prevention of viral outbreaks, interferon (IFN) is among the major defence systems being studied in different species. Fish type I IFNs are known to possess antiviral properties similar to mammalian type I IFNs. In order to stimulate antiviral function, IFN will bind to its cognate receptor, the type I interferon receptor (IFNAR), composed of heterodimeric receptor subunits known as IFNAR1 and IFNΑR2. The binding of type I interferon to receptors assists in the transduction of signals from the external to internal environments of cells to activate biological responses. In order to study the function of IFN, we first need to understand IFN receptors. In this study, we cloned and identified IFNAR1 in orange-spotted grouper (osgIFNAR1) and noted the up-regulated mRNA expression of the receptor and downstream effectors in the head kidney cells with cytokine treatment. The transcriptional expression of osgIFNAR1, which is characterised using polyinosinic-polycytidylic acid (poly[I:C]) and lipopolysaccharide (LPS) treatments, indicated the involvement of osgIFNAR1 in the immune response of grouper. The subcellular localisation of osgIFNAR1 demonstrated scattering across the grouper cell. Viral infection showed the negative feedback regulation of osgIFNAR1 in grouper larvae. Further loss of function of IFNAR1 showed a decreased expression of the virus. This study reported the identification of osgIFNAR1 and characterisation of receptor sensitivity towards immunostimulants, cytokine response, and viral challenge in the interferon pathway of orange-spotted grouper and possible different role of the receptor in viral production. Together, these results provide a frontline report of the potential function of osgIFNAR1 in the innate immunity of teleost.

Abstract
Interleukin (IL)-22, as a member of the interleukin (IL)-10 family, is an important mediator between the immune cells and epithelial tissues during infection and inflammation. This study reported the characterization and mRNA expression patterns of Pf_IL-22 gene and its cell surface-associated receptors Pf_IL-22RA1 and soluble Pf_IL-22RA2 genes in yellow catfish (Pelteobagrus filvidraco). The open reading frames (ORFs) of the Pf_IL-22, Pf_IL-22RA1 and Pf_IL-22RA2 genes were 546 bp, 1740 bp and 690 bp in length, encoding 181, 579 and 229 amino acids, respectively. Alignments of the deduced amino acid sequences present that the Pf_IL-22 has a conserved IL-10 family signature motif, and the Pf_IL-22RA1 and Pf_IL-22RA2 have two conserved fibronectin type-III domains. Quantitative real-time PCR (qPCR) analyses showed that the Pf_IL-22 and Pf_IL-22RA1 mRNAs were highly expressed in mucosal tissues such as the fin, gill, intestine, skin mucus and stomach, and were weakly expressed in the kidney, liver and head kidney of adult yellow catfish, indicating that the Pf_IL-22 transcripts may be mainly produced by mucosal immune cells/tissues in healthy yellow catfish. The mRNA expression levels of the Pf_IL-22RA2 gene were high in the muscle and liver, and were relatively low in the spleen and kidney. The mRNA expression levels of the Pf_IL-22 and its two receptor genes were significantly up-regulated in both mucosal tissues (gill, hindgut, and skin mucus) and systemic immune tissues (spleen, head kidney and blood) after Edwardsiella ictaluri challenge. These results indicated that the Pf_IL-22 and its two receptors genes might play an important role in the innate immune defense against bacterial invasion.

Abstract
Members of the Janus kinase (JAK) family, JAK1 and TYK2 take part in JAK-STAT signaling pathway mediated by interferon in mammalian cells. Similar to the mammalian counterparts, fish JAK1 and TYK2 also perform their potential biological activities by phosphorylating cytokine receptors and STAT. In the present study, Ctenopharyngodon idellus JAK1 (CiJAK1) and TYK2 (CiTYK2) were cloned and identified. The full-length cDNA of CiJAK1 (KT724352.1) is 3829 bp, with an Open Reading Frame (ORF) of 3465 bp encoding a putative protein of 1154 amino acids. The full-length cDNA of CiTYK2 (KT724353.1) is 4337 bp, including an ORF of 3168 bp encoding 1055 amino acids. Structurally, both of them have B41, SH2, TyrKc and TyrKc common domains. CiJAK1 and CiTYK2 share a high degree of homology with their respective counterparts from Danio rerio and Cyprinus carpio by phylogenetic tree analysis. Polyinosinic-polycytidylic acid (Poly I:C), a synthetic dsRNA analogue, can launch the JAK-STAT antiviral signaling pathway. To elucidate the molecular mechanism of Poly I:C initiating the antiviral signaling pathway in fish, C. idellus kidney (CIK) cells were stimulated with Poly I:C and then the cell lysates were separated on 10% SDS-PAGE. The results showed that not only Poly I:C drastically increased the expression level of CiJAK1 and CiTYK2, but also it induced the phosphorylation of CiJAK1 and CiTYK2, as well as C. idellus type I IFN receptor subunits, CiCRFB1 and CiCRFB5. In detail, the levels of p-CiJAK1 and p-CiTYK2 were evidently up-regulated at 3 h post stimulation; however the phosphorylation levels of CiCRFB1 and CiCRFB5 displayed a sharp up-regulation at 12 h post stimulation of Poly I:C. As a basic mechnism of feedback regulation of JAK-STAT signaling pathway, overexpression of CiCRFB1 and CiCRFB5 in CIK cells facilitated the phosphorylation of CiJAK1 and CiTYK2.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 63:10-17. [PMID: 27185203 DOI: 10.1016/j.dci.2016.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2016] [Revised: 05/12/2016] [Accepted: 05/12/2016] [Indexed: 06/05/2023]
Abstract
As one member of ADAR family, ADAR1 (adenosine deaminase acting on RNA 1) can convert adenosine to inosine within dsRNA. There are many ADAR1 splicing isoforms in mammals, including an interferon (IFN) inducible ∼150 kD protein (ADAR1-p150) and a constitutively expressed ∼110 kD protein (ADAR1-p110). The structural diversity of ADAR1 splicing isoforms may reflect their multiple functions. ADAR1 splicing isoforms were also found in fish. In our previous study, we have cloned and identified two different grass carp ADAR1 splicing isoforms, i.e. CiADAR1 and CiADAR1-like, both of them are IFN-inducible proteins. In this paper, we identified a novel CiADAR1 splicing isoform gene (named CiADAR1a). CiADAR1a gene contains 15 exons and 14 introns. Its full-length cDNA is comprised of a 5' UTR (359 bp), a 3' UTR (229 bp) and a 2952 bp ORF encoding a polypeptide of 983 amino acids with one Z-DNA binding domain, three dsRNA binding motifs and a highly conserved hydrolytic deamination domain. CiADAR1a was constitutively expressed in Ctenopharyngodon idella kidney (CIK) cells regardless of Poly I:C stimulation by Western blot assay. In normal condition, CiADAR1a was found to be present mainly in the nucleus. After treatment with Poly I:C, it gradually shifted to cytoplasm. To further investigate the mechanism of transcriptional regulation of CiADAR1a, we cloned and identified its promoter sequence. The transcriptional start site of CiADAR1a is mapped within the truncated exon 2. CiADAR1a promoter is 1303 bp in length containing 4 IRF-Es. In the present study, we constructed pcDNA3.1 eukaryotic expression vectors with IRF1 and IRF3 and co-transfected them with pGL3-CiADAR1a promoter into CIK cells. The results showed that neither the over-expression of IRF1 or IRF3 nor Poly I:C stimulation significantly impacted CiADAR1a promoter activity in CIK cells. Together, according to the molecular and expression characteristics, subcellular localization and transcriptional regulatory mechanism, we deduced that CiADAR1a shared a high degree of homology with mammalian ADAR1-p110.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2016; 61:97-106. [PMID: 27012995 DOI: 10.1016/j.dci.2016.03.020] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Revised: 03/17/2016] [Accepted: 03/18/2016] [Indexed: 06/05/2023]
Abstract
Interferons (IFNs) play crucial roles in the immune response of defense against viral infection and bacteria invasion. In the present study, we systematically identified and characterized the IFNs, their regulatory factors (Interferon Regulatory Factors, IRFs) and receptors (Cytokine Receptor Family B, CRFBs) in grass carp (Ctenopharyngodon idella). Grass carp IFNs can be classified into type I IFN (IFN-I) and type II IFN (IFN-II) like other teleosts. IFN-I consist of two groups with two (group I) or four (group II) cysteines in the mature peptide and can be further divided into three subgroups (IFN-a, -c and -d), containing four members: IFN1, IFN2, IFN3, IFN4 in grass carp. IFN-II contain two members, IFNγ2 with the similarity to mammalian IFNγ and a cyprinid specific IFNγ1 (IFNγ-rel) molecule. mRNA expression analyses of IFNs discovered that IFN1 and IFN-II were sustainably expressed in many tissues, while other IFN members were transiently expressed in specific tissues and time points. In the immune response, IFN transcriptions are primarily regulated through multiple IRFs after grass carp reovirus (GCRV) challenge. IRF family possess thirteen members in grass carp, which can be further divided into four subfamilies (IRF-1, -3, -4 and -5 subfamily), each of them plays different roles in the innate and adaptive immunity via various signaling pathways to interact with IFNs (mainly IFN-I). IFNs have to bind receptors (CRFBs) to perform their functions. CRFBs as IFN receptors contain six members in grass carp. The structure and expression characterizations of IFNs, IRFs and CRFBs were analyzed using bioinformatics tools. These results might provide basic data for the further functional research of IFN system, and deeply understand fish immune mechanisms against virus infection.
