Abstract
Macrobrachium rosenbergii Taihu virus (MrTV) is a virulent pathogen that mainly threatens M. rosenbergii larvae. Rab proteins, which are essential for controlling intracellular membrane trafficking, are hijacked by multiple viruses to complete their life cycle. In this paper, we studied the function of M. rosenbergii Rab1A (MrRab1A) in the MrTV infection. Upon MrTV infection, the transcription level of MrRab1A was significantly up-regulated, indicating MrRab1A was a MrTV responsive gene and might be important for MrTV infection. Co-IP and co-localization assays revealed that MrRab1A could directly bind with MrTV and its capsid protein VP3. Moreover, the in vivo neutralization assay demonstrated that pre-incubation of MrTV with recombinant MrRab1A could partially block MrTV infection. These findings indicated that MrRab1A functioned as a virus-binding protein involved in MrTV infection, which shed new light on the mechanism of MrTV infection and provided a potential target for developing anti-MrTV therapies.

Abstract
Spring viremia of carp virus (SVCV) is strongly contagious and pathogenic to common carp and cyprinoid species. However, knowledge of how SVCV enters host cells is still inadequate. In this study, mass spectrometry (MS) was incorporated with tandem affinity purification (TAP) to identify host proteins that interact with SVCV glycoprotein, the main attachment protein of SVCV. Specifically, prohibitin (PHB) received the utmost attention from all the candidate proteins, and its interaction with the SVCV-G protein was confirmed by immunoprecipitation and immunofluorescence assays. Treatment with PHB-specific inhibitors or knockdown of the expression of PHB by siRNAs resulted in a marked reduction in binding and entry of SVCV on host cells, while overexpression of PHB increased SVCV attachment and invasion. Furthermore, binding of SVCV to ZF4 and FHM cells was inhibited by pre-incubating the virus with recombinant PHB protein (rPHB) or blocking the cell surface PHB with its polyclonal antibodies. In addition, overexpression of PHB on SVCV-nonpermissive Grouper spleen cells (GSs) conferred susceptibility to SVCV infection. In vivo, treatment of rPHB could significantly inhibit SVCV propagation within zebrafish and benefit the survival rate of SVCV-infected zebrafish. These results demonstrate that PHB plays a crucial role in both the attachment and entry stages of SVCV infection.

Abstract
Spring viremia of carp virus (SVCV) usually be considered as one of the serious in viral diseases of aquaculture, and DNA vaccine with novel delivery mechanism or adjuvant has proven to be a promising and effective strategy to control aquatic animal diseases. In this study, the mannose-modified chitosan, a carrier system for vaccine delivery, were used to developed a chitosan-encapsulated DNA vaccine (CS-M-G) against SVCV, then investigated immune response induced by the vaccine. Our results showed that CS-M-G was confirmed the spherical or elliptical with even distribution and ranging from approximately 50 to 150 nm in size, the expression of the antigen gene could still be detected after 21 d post vaccination. The CS-M-G induces the highest antibody levels in the 20 μg dose group which is about 3 times than naked plasmid group at 21 d post vaccination, and still hold a higher level than control group at 28 d post vaccination. On the side, strongest protection with relative percent survival of 62.1% in the 20 μg CS-M-G group, which could produce significantly higher enzyme activities and up-regulated expression of immune-associated genes than control group. Thus, our results indicate that DNA vaccine loaded with mannose-modified chitosan induces strong immune response and provided an effective protection against SVCV infection, may be helpful and extended for developing more aquatic animal vaccines in the future.

Abstract
Immersion vaccination of single-walled carbon nanotubes loaded with mannose-modified glycoprotein (SWCNTs-MG) vaccine has been proved to be effective in preventing spring viraemia of carp virus (SVCV). Immunization procedure has immense consequence on the immune effect of the immersion vaccine. However, immunization procedure optimization for SWCNTs-MG vaccine against SVCV has not been reported. In this study, accordingly, a full-factor experiment was designed to optimize the immunization procedure of SWCNTs-MG vaccine by three aspects of vaccine dose (30 mg/L, 40 mg/L and 50 mg/L), immunization density (8 fish L-1 , 24 fish L-1 and 48 fish L-1 ) and immunization time (6, 12 and 24 hr). Furthermore, we used the immunization group (A1B2C1, 30 mg/L, 24 fish L-1 and 6 hr) in the previous study as a positive control (PC) to evaluate the immunization effect optimized conditions from the expression of immune-related genes and relative percentage survival (RPS). At 28 days post-vaccination (DPV), common carps were intraperitoneal injected SVCV challenged test indicated that the A1B2C2 group (30 mg/L, 24 fish L-1 , 12 hr) displayed superiority of protective efficacy compare with other groups and the RPS with 77.9%, which was 15.6% higher than the PC group of RPS with 62.3%. Moreover, the expression of immune-related genes such as IL-10, CD4 and MHC-II was also significantly higher than PC group. The specific experimental flow chart is shown in Figure 1. Conclusively, these results demonstrated that vaccine dose, immunization density and immunization time are 30 mg/L, 24 fish L-1 and 12 hr, which is the more appropriate immunization programme with juvenile carp for SWCNTs-MG vaccine. This study provides a profitable reference for improving the immune efficiency of aquatic immersion vaccine. [Figure: see text].

Abstract
As a fierce pathogen, spring viremia of carp virus (SVCV) can cause high mortality in the common carp, and its glycoprotein (G protein) is a component of the viral structure on the surface of virion, which is crucial in viral life cycle. This report adopted tandem affinity purification (TAP), mass spectrometry analysis (LC-MS/MS), immunoprecipitation, and confocal microscopy assays to identify Heat shock cognate protein 70 (HSC70) as an interaction partner of SVCV G protein. It was found that HSC70 overexpression dramatically inhibited SVCV replication, whereas its loss of functions elicited opposing effects on SVCV replication. Mechanistic studies indicate that HSC70 induces lysosomal degradation of ubiquitinated-SVCV G protein. This study further demonstrates that Membrane-associated RING-CH 8 (MARCH8), an E3 ubiquitin ligase, is critical for SVCV G protein ubiquitylation and leads to its lysosomal degradation. Furthermore, the MARCH8 mediated ubiquitylation of SVCV G protein required the participation of HSC70 through forming a multicomponent complex. Taken together, these results demonstrate that HSC70 serves as a scaffold for MARCH8 and SVCV G, which leads to the ubiquitylation and degradation of SVCV G protein and thus inhibits viral replication. These findings have established a novel host defense mechanism against SVCV.

Abstract
SVCV infection is known to activate the host's innate immune responses, including the production of interferon (IFN) and interferon-stimulated genes (ISGs). Viperin_sv1 is a novel splice variant of viperin, which is induced during SVCV infection and proves to positively regulate the IFN activation and production. However, the underlying mechanism remains unsolved. In this study, the P protein of SVCV was identified to be the key to induce the mRNA modification and production of viperin_sv1 during the virus infection. Besides, Viperin_sv1 was able to trigger the RLR signaling cascades to activate type-1 interferon response. Additional analysis revealed that viperin_sv1 promoted the stability and function of RIG-I, which result in the production of IFN and ISGs. Moreover, the central SAM domain of viperin_sv1 was demonstrated to be essential for regulating RIG-I protein expression and inducing IFN production. Furthermore, this study also showed that SVCV replication could be inhibited by the viperin_sv1 SAM domain. In conclusion, our study demonstrates that viperin_sv1 reduces the replication of SVCV by promoting the RIG-I protein expression. Our findings identified the antiviral function played by the SAM domain of viperin_sv1 and suggested an antiviral mechanism that is conserved among different species.

Abstract
YWHAB is a PCV2 ORF5-interacting host factor. YWHAB expression is activated by PCV2 infection and ORF5 transfection. YWHAB inhibits PCV2 replication. YWHAB alleviates PCV2 infection induced ERS, autophagy, ROS production and apoptosis.
Porcine circovirus type 2 (PCV2) infection causes porcine circovirus associated diseases (PCVAD) worldwide. Identification of host factors that interact with viral proteins is a fundamental step to understand the pathogenesis of PCV2. Our previous study reported that ORF5, a newly identified PCV2 viral protein supports PCV2 replication and interacts with multiple host factors. Here, we showed that a host factor YWHAB is an ORF5-interacting protein and plays essential roles during PCV2 infection. By using protein-protein interaction assays, we confirmed that YWHAB directly interacts with PCV2-ORF5 protein. We further showed that YWHAB expression was potently induced upon ORF5 overexpression and PCV2 infection. Remarkably, we found that the YWHAB strongly inhibited PCV2 replication, suggesting its role in defending PCV2 infection. By using the ectopic overexpression and gene knockdown approaches, we revealed that YWHAB inhibits PCV2-induced endoplasmic reticulum stress (ERS), autophagy, reactive oxygen species (ROS) production and apoptosis, suggesting its vital role in alleviating PCV2-induced cellular damage. Together, this study demonstrated that an ORF5-interacting host factor YWHAB affects PCV2 infection and PCV2-induced cellular response, which expands the current understanding of YWHAB biological function and might serves as a new therapeutic target to manage PCV2 infection-associated diseases.

Abstract
Tripartite motif (TRIM) proteins have attracted particular research interest because of their multiple functions in the antiviral innate immune response. TRIM proteins perform different functions during virus infection, some play a role in inhibiting while others play a role in promoting. In this study, we described a species-specific TRIM gene named ftr67. Analysis of tissue distribution showed that ftr67 was mainly expressed in the gill and liver in five examined tissues of zebrafish. The phylogenic analysis showed that ftr67 was closest to the grass carp TRIM67. Overexpression of ftr67 resulted in a significantly decreased SVCV entry and impaired SVCV replication in FHM cells. Furthermore, overexpression of ftr67 could significantly induce the upregulation of molecular sensor RIG-I, IRF3/7, IFN and ISGs. In addition, RING domain of ftr67 was a required part essential for the antiviral effect. In summary, our results demonstrated that the important role of ftr67 in regulating SVCV infection, which offers a potential target for development of anti-SVCV therapies.

Abstract
Transcriptional programs regulated by the NF-κB family are essential for the inflammatory response as well as for innate and adaptive immunity. NF-κB activation occurs via two major signaling pathways: the canonical and the noncanonical. The canonical NF-κB pathway responds to diverse immune stimulations and leads to rapid but transient activation. As a member of the canonical NF-κB family, p65 is thought to be a key regulator of viral infection. Because of the embryonic lethality of p65-null mice, the physiological role of p65 in the antiviral immune response is still unclear. In this study, we generated p65-null zebrafish, which were viable and indistinguishable from their wildtype (WT) siblings under normal conditions. However, p65-null zebrafish were more sensitive to spring viremia of carp virus infection than their WT siblings. Further assays indicated that proinflammatory and antiviral genes, including IFN, were downregulated in p65-null zebrafish after spring viremia of carp virus infection compared with their WT siblings. Our results thus suggested that p65 is required for the antiviral response, activating not only proinflammatory genes but also antiviral genes (including IFN).

Liu L, Qiu TX, Song DW, Shan LP, Chen J. Inhibition of a novel coumarin on an aquatic rhabdovirus by targeting the early stage of viral infection demonstrates potential application in aquaculture. Antiviral Res 2019; 174:104672. [PMID: 31825851 DOI: 10.1016/j.antiviral.2019.104672] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 11/29/2019] [Accepted: 12/02/2019] [Indexed: 12/24/2022]
Abstract
Spring viremia of carp virus (SVCV) is one of the most serious pathogens in aquaculture, resulting in devastating damage in cyprinid. In this study, we designed and synthesized a novel coumarin derivative (C3007) for evaluating its in vitro and in vivo anti-SVCV effects. Here, we determined that up to 25 mg/L C3007 significantly decreased SVCV protein gene expression levels in EPC cells by a maximum inhibitory rate of >95%. When C3007 was preincubated with SVCV, infectivity was significantly inhibited in vitro in a time-dependent manner, with complete inhibition at 25 mg/L. For in vivo studies, C3007 exhibited an anti-SVCV effect by substantially enhancing the survival rate of virus-infected fish via intraperitoneal injection. Although the horizontal transmission of SVCV was hindered by C3007 in a static cohabitation challenge model, it was not completely blocked, showing that the viral loads in recipient fish were obviously reduced. Thus, C3007 could potentially be used as a therapeutic agent with great potential in aquatic systems and may also be suitable for applications in pond aquaculture settings against viral transmission. Additionally, the C3007-preincubated virus induced an antiviral immune response with high levels of IFN expression, suggesting that C3007 pre-treatment could be used in vaccine development.

Abstract
The tripartite motif (TRIM) family involves many cellular processes, including fundamental functions in antiviral immunity. Antiviral activities of TRIMs are reported in a variety of patterns, and one of the most significant channels is related to the activation of the type-I interferon (IFN) pathway. In this study, we described a fintrim (ftr) gene named ftr36, which is mainly expressed in the gills, skin, and intestines. This study shows that ftr36 encodes a protein affording a potent antiviral effect. In vitro, overexpression of FTR36 mediated an upregulated pattern of recognition receptor retinoic acid-inducible gene I (RIG-I), interferon regulatory factor 3/7(IRF3/7), IFN, and IFN-stimulated genes (ISGs) expression. Thereby, FTR36 expression could afford host defense against the spring viremia of carp virus (SVCV) and the giant salamander iridovirus (GSIV). With the deletion of the RING domain or B30.2 domain separately, the antiviral ability of FTR36 was abolished partially and almost lost its ability to activate the IFN-pathway. These findings indicate that both RING and B30.2 domains are indispensable for the antiviral activity of FTR36. Altogether, this study described a finTRIM FTR36, which can activate IFN-pathways and stimulate ISGs to provide host defense against viral infections.
