BIOLOGY 2023; 12:1145. [PMID: 37627029 PMCID: PMC10452491 DOI: 10.3390/biology12081145] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 08/07/2023] [Accepted: 08/16/2023] [Indexed: 08/27/2023]
Abstract
Hirame novirhabdovirus (HIRRV) is one of most serious viral pathogens causing significant economic losses to the flounder (Paralichthys olivaceus)-farming industry. Previous studies have shown that the outbreak of HIRRV is highly temperature-dependent, and revealed the viral replication was significantly affected by the antiviral response of flounders under different temperatures. In the present study, the proteome and phosphoproteome was used to analyze the different antiviral responses in the HIRRV-infected flounder under 10 °C and 20 °C. Post viral infection, 472 differentially expressed proteins (DEPs) were identified in the spleen of flounder under 10 °C, which related to NOD-like receptor signaling pathway, RIG-I-like receptor signaling pathway, RNA transport and so on. Under 20 °C, 652 DEPs were identified and involved in focal adhesion, regulation of actin cytoskeleton, phagosome, NOD-like receptor signaling pathway and RIG-I-like receptor signaling pathway. Phosphoproteome analysis showed that 675 differentially expressed phosphoproteins (DEPPs) were identified in the viral infected spleen under 10 °C and significantly enriched in Spliceosome, signaling pathway, necroptosis and RNA transport. Under 20 °C, 1304 DEPPs were identified and significantly enriched to Proteasome, VEGF signaling pathway, apoptosis, Spliceosome, mTOR signaling pathway, mRNA surveillance pathway, and RNA transport. To be noted, the proteins and phosphoproteins involved in interferon production and signaling showed significant upregulations in the viral infected flounder under 20 °C compared with that under 10 °C. Furthermore, the temporal expression profiles of eight selected antiviral-related mRNA including IRF3, IRF7, IKKβ, TBK1, IFIT1, IFI44, MX1 and ISG15 were detected by qRT-PCR, which showed a significantly stronger response at early infection under 20 °C. These results provided fundamental resources for subsequent in-depth research on the HIRRV infection mechanism and the antiviral immunity of flounder, and also gives evidences for the high mortality of HIRRV-infected flounder under low temperature.

Protective efficacy evaluation of immunogenic protein AHA_3793 of Aeromonas hydrophila as vaccine candidate for largemouth bass Micropterus salmoides. JOURNAL OF OCEANOLOGY AND LIMNOLOGY 2022; 41:392-400.

Abstract
Aeromonas hydrophila is a Gram-negative pathogen that can infect various fish, including largemouth bass (Micropterus salmoides), which have caused huge economic losses. In present study, largemouth bass anti-A. hydrophila antibodies were produced, then a highly immunogenic outer membrane proteins, AHA_3793, was identified by combined western blotting and mass spectrometry analysis. Moreover, AHA_3793 was expressed, and its immunogenicity was further verified by western blotting. Subsequently, the protective efficacy of AHA_3793 were evaluated in largemouth bass. The results showed that rAHA_3793 could produce a relative percentage survival (RPS) of 61.76% for largemouth bass against A. hydrophila challenge. ELISA analysis showed the specific serum antibodies of largemouth bass against rAHA_3793 and A. hydrophila in vaccinated group in weeks 4 and 5 after immunization were significantly higher than those in control group, which suggested that rAHA_3793 induced production of specific serum antibodies against rAHA_3793 and A. hydrophila. The qRT-PCR analysis showed that expressions of CD4-2 and MHC IIα were also significantly up-regulated after immunization. These results collectively demonstrated that rAHA_3793 could induce a strong humoral immune response of largemouth bass, and then produce high immune protection effects against A. hydrophila infection.

Vaccination with live Hirame novirhabdovirus (HIRRV) at temperature-controlled condition induced protective immunity in flounder (Paralichthys olivaceus). Microb Pathog 2021; 157:104993.

Abstract
Hirame novirhabdovirus (HIRRV) is a severe viral pathogen of flounder resulting in significant losses to the aquaculture industry. However, the mortality due to the disease would be significantly reduced when the water temperature was increased from 10 to 20 °C. In this study, we examined the potentiality of vaccination with live HIRRV under a temperature-controlled culture condition for development of protective immunity in flounder. Flounders were infected with HIRRV at 10 °C and maintained for 2 days, and then the temperature was shift up to 20 °C. When the temperature was further shift down to 10 °C at 7 (S-7 group), 14 (S-14 group) or 21 (S-21 group) days post infection (dpi), mortality rates of 60%, 13.33% and 0 were observed, respectively. To investigate the development of protective immunity of survived flounder, a re-challenge was performed and a highest survival rate of 80% was found in S-21 group, which was significantly higher than S-14 group (65%) and S-7 group (45%). Moreover, it was found that a lower viral load was detected in the flounder maintained at 20 °C for a longer time, and a longer maintaining of survived flounder at 20 °C would also elicit higher percentages of IgM + B lymphocytes and specific antibodies levels. Notably, a significantly higher levels of specific antibodies were detected post re-challenge compared with the first peak level after initial infection. Therefore, these demonstrated that the initial infection with live HIRRV under a temperature-controlled condition elicited an effective protective immune response against HIRRV, and maintaining at 20 °C for a long enough time would allow the HIRRV-infected flounder to eliminate the virus completely and acquired a protective immunity against HIRRV infection. This is the first study showing the possibility of developing an effective preventive measure against HIRRV by vaccination with live virus under controlled water temperature.

Microb Pathog 2021; 154:104868. [PMID: 33771630 DOI: 10.1016/j.micpath.2021.104868] [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: 11/06/2020] [Revised: 03/04/2021] [Accepted: 03/04/2021] [Indexed: 11/15/2022]
Abstract
Hirame rhabdovirus (HIRRV) is one of the most important viruses of fish, posing a great threat to the fish industry in Asia and Europe. The glycoprotein (G) of HIRRV is known to play important roles in virus attachment and entry, making it an ideal target for both diagnosis and therapy. In this study, a truncated G of HIRRV was expressed as a fusion protein in Escherichia coli. Using the recombinant G protein (rG), monoclonal antibodies (mAbs) were prepared by the hybridoma technology. Subsequently, positive clones were screened by indirect enzyme-linked immunosorbent assay (ELISA) and further characterized by Western blot and immunofluorescence assay (IFA). ELISA results showed that two mAbs (3E5 and 4D10) could react with the rG, as well as the purified HIRRV. Western blot analysis showed that the mAbs belong to the IgG isotype and could recognize a 60 kDa viral protein, which is consistent with the molecular weight of G protein and determined to be the G protein of HIRRV by mass spectrometry. The virions in HIRRV-infected EPC could also be recognized by two mAbs in IFA. Moreover, neutralization assay showed that mAb 4D10 could significantly inhibit the proliferation of HIRRV and delay the development of cytopathic effect in viral-infected EPC cells, and in vivo neutralization assay also showed that mAb 4D10 could significantly reduce the mortality of HIRRV-infected flounder, indicating that mAb 4D10 can partially neutralize the HIRRV infection. Western blot analysis showed that mAb 4D10 could specifically bind the C-terminal domain of HIRRV-G protein. These results demonstrated that the produced mAbs could specifically recognize the G protein of HIRRV and displayed virus-neutralizing activity in vitro and in vivo, which could serve as effective detection probes and potential neutralizing antibodies for HIRRV.
