FISH & SHELLFISH IMMUNOLOGY 2024; 146:109403. [PMID: 38266793 DOI: 10.1016/j.fsi.2024.109403] [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: 12/12/2023] [Revised: 01/20/2024] [Accepted: 01/21/2024] [Indexed: 01/26/2024]
Abstract
The high morbidity and mortality of Macrobrachium nipponense occurred in several farms in China, with cardinal symptoms of slow swimming, loss of appetite, empty of intestine, reddening of the hepatopancreas and gills. The pathogen has been confirmed as Decapod Iridescent Virus 1 (DIV1), namely DIV1-mn, by molecular epidemiology, histopathological examination, TEM observation, challenge experiment, and viral load detection. Histopathological analysis showed severe damage in hepatopancreas and gills of diseased prawns, exhibited few eosinophilic inclusions and pyknosis, and TEM of diseased prawns revealed that icosahedral virus particles existed in hepatopancreas and gill, which confirmed the disease of the farmed prawns caused by the DIV1 infection. Besides, challenge tests showed LD50 of DIV1 to M. nipponense was determined to be 2.14 × 104 copies/mL, and real-time PCR revealed that M. nipponense had a very high DIV1 load in the hemocytes, gills and hepatopancreas after infection. Furthermore, qRT-PCR was undertaken to investigated the expression of six immune-related genes in DIV1-infected M. nipponense after different time points, and the results revealed UCHL3, Relish, Gly-Cru2, CTL, MyD88 and Hemocyanin were significantly up-regulated in hemocytes, gills and hepatopancreas, which revealed various expression patterns in response to DIV1 infection. This study revealed that DIV1 infection is responsible for the mass mortality of M. nipponense, one of the important crustacean species, indicating its high susceptibility to DIV1. Moreover, this study will contribute to exploring the interaction between the host and DIV1 infection, specifically in terms of understanding how M. nipponense recognizes and eliminates the invading of DIV1.

Abstract
Annexin (Anx) family protein is a highly conserved protein family that plays important roles in immune defense of vertebrates and invertebrates against invading pathogens. In this study, a novel Anx was cloned and characterized from the red claw crayfish, Cherax quadricarinatus. The Open Reading Frame of CqAnxB9 consisted of 930 nucleotide bases pair and encoded 309 amino acids. The CqAnxB9 protein contained three repeat Anx domains and a typical KGLGT sequence. Tissue expression analysis showed that the expression levels of CqAnxB9 were mainly expressed in the intestine, hepatopancreas and hemocytes. After WSSV challenge, CqAnxB9 expression was up-regulated in the hematopoietic tissue (Hpt) cells. Moreover, knockdown of CqAnxB9 inhibited WSSV replication and VP28 expression, suggesting that CqAnxB9 plays a positive role in WSSV infection. Further studies revealed that recombinant CqAnxB9 protein was found to bind to the viral envelop protein VP28. All these findings indicate that new-found CqAnxB9 is likely to promote WSSV infection in crustaceans, which provides a better understanding of the pathogenesis of WSSV.

Abstract
The family of TRIM proteins with E3 ubiquitin ligase activity served important roles in the regulation of innate immune processes, in particular antiviral and proinflammatory cytokine responses. In this study, a novel TRIM37 homolog was identified from Penaeus monodon (named PmTRIM37). The PmTRIM37 protein contained three conserved domains (one RING finger domain, a B-box, and one Coiled-coil region) at its N-terminal and one Meprin and MATH domain at its C-terminal. The MATH domain was the characteristic of TRIM37 family. PmTRIM37 has relatively high expression in immune-related tissues such as hepatopancreas, gills, lymphoid organs and hemocytes. The expression levels of PmTRIM37 in hepatopancreas and lymphoid organs were significantly up-regulated after white spot syndrome virus (WSSV) infection. Knock down of PmTRIM37 promoted WSSV replication and VP28 expression, suggesting that PmTRIM37 played a negative role in WSSV infection. Further studies revealed that PmTRIM37 positively regulated the NF-κB pathway and Antimicrobial peptides (AMP) expression during WSSV infection. These findings indicated that PmTRIM37 might restrict WSSV replication by positively regulating NF-κB pathway during WSSV infection in P. monodon.

Eight TRIM32 isoforms from oriental river prawn Macrobrachium nipponense are involved in innate immunity during white spot syndrome virus infection. FISH & SHELLFISH IMMUNOLOGY 2022; 131:368-380.

Abstract
Tripartite motif (TRIM) proteins comprise a large family of RING-type ubiquitin E3 ligases that regulate important biological processes. In this study, full-length MnTRIM32 cDNA was obtained from oriental river prawn Macrobrachium nipponense, and eight MnTRIM32 isoforms generated by alternative splicing were identified. The open reading frames of the eight MnTRIM32 isoforms were predicted to be separately composed of 402, 346, 347, 346, 414, 358, 359, and 358 amino acid residues. Protein structural analysis revealed that all MnTRIM32 isoforms contained a RING domain and a coiled coil region. MnTRIM32 was ubiquitously expressed in all tissues tested, with the highest expression in the hepatopancreas. The mRNA levels of MnTRIM32 in the gills, stomach, and intestine of prawns were found to undergo time-dependent enhancement following white spot syndrome virus (WSSV) stimulation. Double-stranded RNA interference studies revealed that MnTRIM32 silencing significantly downregulated the expression levels of interferon (IFN) regulatory factor MnIRF, IFN-like factor MnVago4, and tumor necrosis factor MnTNF. Furthermore, knockdown of MnTRIM32 in WSSV-challenged prawns increased the expression of VP28 and the number of WSSV copies, suggesting that MnTRIM32 plays a positive role in limiting WSSV infection. These findings provided strong evidence for the important role of MnTRIM32 in the antiviral innate immunity of M. nipponense.

Abstract
The TRIpartite Motif (TRIM) proteins play key roles in cell differentiation, apoptosis, development, autophagy, and innate immunity in vertebrates. In the present study, a novel TRIM9 homolog (designated as LvTRIM9-1) specifically expressed in the lymphoid organ of shrimp was identified from the Pacific whiteleg shrimp Litopenaeus vannamei. Its deduced amino acid sequence possesses the typical features of TRIM proteins, including a RING domain, two B-boxes, a coiled-coil domain, a FN3 domain, and a SPRY domain. The transcripts of LvTRIM9-1 were mainly located in the lymphoid tubules of the lymphoid organ. Knockdown of LvTRIM9-1 could apparently inhibit the transcriptions of some genes from white spot syndrome virus (WSSV) and reduce the viral propagation in the lymphoid organ. Overexpression of LvTRIM9-1 in mammalian cells could activate the promoter activity of NF-κB, and an in vivo experiment in shrimp showed that knockdown of LvTRIM9-1 reduced the expression of LvRelish in the lymphoid organ. Yeast two-hybridization and co-immunoprecipitation (Co-IP) assays confirmed that LvTRIM9-1 could directly interact with LvIMD, a key component of the IMD pathway, through its SPRY domain. These data suggest that LvTRIM9-1 could activate the IMD pathway in shrimp via interaction with LvIMD. This is the first evidence to show the regulation of a TRIM9 protein on the IMD pathway through its direct interaction with IMD, which will enrich our knowledge on the role of TRIM proteins in innate immunity of invertebrates.

Abstract
Tripartite motif-containing proteins (TRIMs), exhibiting ubiquitin E3 ligase activity, are involved in regulation of not only autophagy and apoptosis but also pyrotosis and antiviral immune responses of host cells. TRIMs play important roles in modulating signaling pathways of antiviral immune responses via type I interferon, NF-κB, Janus kinase/signal transducer and activator of transcription (JAK/STAT), and Nrf2. However, viruses are able to antagonize TRIM activity or evenly utilize TRIMs for viral replication. This communication presents the current understanding of TRIMs exploited by viruses to evade host immune response.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 123:104146.

Abstract
Tripartite motif (TRIM) proteins are a large family of E3 ubiquitin ligases involved in many biological processes, such as inflammation and antiviral immunity. In the present study, a novel TRIM protein homolog named CgTRIM1 was identified from Pacific oyster Crassostrea gigas. The open reading frame (ORF) of CgTRIM1 was of 1914 bp encoding a putative polypeptide of 637 amino acid residues. There were three classical domains in the predicted CgTRIM1 protein, including one RING domain, two b-box domains and one coiled-coil domain in N-terminal. For the lack of C-terminal domains, the CgTRIM1 was classified as the member of C-V TRIM subfamily. The mRNA transcripts of CgTRIM1 were detected in all the tested tissues and haemocytes, with the highest expression level in gill. The mRNA and protein levels of CgTRIM1 in gill were significantly up-regulated at 6 h after poly (I:C) stimulation. Moreover, the nuclear translocation of CgTRIM1 was observed in haemocytes of oysters after poly (I:C) stimulation. After IFN-like protein (CgIFNLP) was knocked down by RNA interference (RNAi), the expression of CgTRIM1 in gill was markedly inhibited in both mRNA (0.14-fold, p < 0.001) and protein levels after poly (I:C) stimulation. Furthermore, after knocking down of CgTRIM1, the mRNA expression levels of IFN-stimulated genes, including myxovirus resistance of oyster (CgMx) and Interferon-induced protein 44 (CgIFI44) were significantly down-regulated post poly (I:C) stimulation, while no significant change of the CgIFNLP expression was observed. These results indicated that CgTRIM1 participated in the antiviral response of C. gigas by regulating the mRNA expressions of IFN-stimulated genes.

Abstract
Some members of genus Macrobrachium are important economically prawns and valuable objects for studying the innate immune defense mechanism of crustaceans. Studies have focused on immune responses against bacterial and fungal infections and have expanded to include antiviral immunity over the past two decades. Similar to all living organisms, prawns are exposed to viruses, including white spot syndrome virus, Macrobrachium rosenbergii nodavirus, and Decapod iridescent virus 1 and develop effective defense mechanisms. Here, we review current understanding of the antiviral host defense in two species of Macrobrachium. The main antiviral defense of Macrobrachium is the activation of intracellular signaling cascades, leading to the activation of cellular responses (apoptosis) and humoral responses (immune-related signaling pathways, antimicrobial and antiviral peptides, lectins, and prophenoloxidase-activating system).
