Genomic and transcriptome insight into the structure and immunity role of TRIM proteins in Chinese soft-shelled turtles (Pelodiscus sinensis) after Aeromonas hydrophila infection.

Abstract
BACKGROUND TRIM proteins, recognized as a class of E3 ubiquitin ligases, are increasingly acknowledged for their antipathogen immune functions in mammals and fish. In the Chinese soft-shelled turtle (Pelodiscus sinensis), a secondary aquatic reptile that occupies a unique evolutionary position, the TRIM gene has rarely been reported. METHODS AND RESULTS In the present study, 48 PsTRIM proteins were identified from the genome of Pelodiscus sinensis via Hidden Markov Model (HMM) searches and Signal Transduction ATPases with Numerous Domains (SMART) analysis. These PsTRIMs were found across 43 distinct scaffolds, and phylogenetic analyses classified them into three principal clades. The PsTRIMs feature a conserved assembly of either RING-B-box-coiled-coil (RBCC) or B-box-coiled-coil (BBC) domains at the N-terminus, in addition to eight unique domains at the C-terminus, including the B30.2 domain, 19 of which were identified. Expression profiling revealed ubiquitous expression of the 48 PsTRIMs across various P. sinensis tissues. Notably, seven PsTRIMs exhibited significant differential expression in liver transcriptomes following infection with Aeromonas hydrophila. Weighted gene coexpression network analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis implicated PsTRIM14 and PsTRIM28 as key players in host defense against bacterial invasion. Real-time quantitative PCR results indicated that PsTRIM1, PsTRIM2, PsTRIM14, and PsTRIM28 experienced marked upregulation in P. sinensis livers at 12 h post-infection with A. hydrophila. CONCLUSIONS Our study is the first to comprehensively identify and analyze the functions of TRIM genes in P. sinensis, unveiling their considerable diversity and potential roles in modulating immune responses.

Abstract
TRIM proteins are characterized by their conserved N-terminal RING, B-box, and coiled-coil domains. These proteins are efficient regulators of autophagy, apoptosis, and innate immune responses and confer immunity against viruses and bacteria. TRIMs function as receptors or scaffold proteins that target substrates for autophagy-mediated degradation. Most TRIMs interact with the BECN1-ULK1 complex to form TRIMosomes, thereby efficiently targeting substrates to autophagosomes. They regulate the functions of ATG proteins through physical interactions or ubiquitination. TRIMs affect the lipidation of MAP1LC3B1 to form MAP1LC3B2, which is a prerequisite for phagophore and autophagosome formation. In addition, they regulate MTOR kinase and TFEB, thereby regulating the expression of ATG genes. TRIM proteins are efficient regulators of apoptosis and are crucial for regulating cell proliferation and tumor formation. Many TRIM proteins regulate intrinsic and extrinsic apoptosis via the cell surface receptors TGFBR2, TNFRSF1A, and FAS. Mitochondria modulate the anti- and proapoptotic functions of BCL2, BAX, BAK1, and CYCS. These proteins use a multipronged approach to regulate the intrinsic and extrinsic apoptotic pathways, culminating in coordinated activation or inhibition of the initiator and executor CASPs. Furthermore, TRIMs can have a dual effect in determining cell fate and are therefore crucial for cellular homeostasis. In this review, we discuss mechanistic insights into the role of TRIM proteins in regulating autophagy and apoptosis, which can be used to better understand cellular physiology. These findings can be used to develop therapeutic interventions to prevent or treat multiple genetic and infectious diseases.

Abstract
Innate immunity plays the most important system responsible for protecting crustaceans against invading pathogens. White spot syndrome virus (WSSV) is considered a serious pathogen in crustaceans with high cumulative mortality and morbidity in infected animals. Understanding the mechanism of the response of hosts to WSSV infection is necessary, which is useful for effective prevention in controlling infection. In this review, we summarize the participation of signaling pathways (toll, immune deficiency, JAK/STAT, endocytosis, mitogen-activated protein kinase, PI3K/Akt/mTOR, cGAS-STING, Wingless/Integrated signal transduction, and prophenoloxidase (proPO) cascade) and the activity of cells (apoptosis, autophagy, as well as, reactive oxygen species and antioxidant enzymes) in the cellular-mediated immune response of crustaceans during WSSV infection. The information presented in this current review is important for a better understanding of the mechanism of the response of hosts to pathogens. Additionally, this provides a piece of basic knowledge for discovering approaches to strengthen the immune system and resistance of cultured animals against viral infections.

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.

Genes (Basel) 2023; 14:1555. [PMID: 37628607 PMCID: PMC10454932 DOI: 10.3390/genes14081555] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 07/25/2023] [Accepted: 07/27/2023] [Indexed: 08/27/2023] Open
Abstract
Rabies remains a great threat to public health worldwide. So far, the mechanism of rabies virus (RABV) infection is not fully understood, and there is no effective treatment for rabies. Identifying more host restriction factors of RABV will spur the development of novel therapeutic interventions against rabies. Accumulating studies suggest that tripartite motif-containing (TRIM) proteins have great effects on virus replication. TRIMs control the antiviral responses through either direct interaction with viral proteins or indirect regulation of innate immune signaling molecules in the host. The role of TRIM25 in rabies virus (RABV) infection is poorly understood. Using next-generation sequencing, we found that TRIM25 is upregulated during HEP-Flury infection. Knockdown of TRIM25 enhances HEP-Flury production, while overexpression of TRIM25 suppresses HEP-Flury replication. Knockdown of interferon α and interferon β weakens the anti-RABV response induced by TRIM25 overexpression, and potentiates RABV production. Furthermore, we found that TRIM25 regulates type-I interferon response by targeting retinoic acid-inducible gene I (RIG-I) during HEP-Flury infection. Knockdown of RIG-I weakens the anti-HEP-Flury response induced by TRIM25 overexpression, indicating that TRIM25 regulates RABV production via the RIG-I-IFN axis. In addition, we observed that TRIM25 does not directly interact with HEP-Flury structural proteins, suggesting that TRIM25 regulates HEP-Flury production indirectly. Taken together, our work identifies TRIM25 as a new host factor involved in HEP-Flury infection, which may be a potential target for the development of antiviral drugs against RABV.

Abstract
Rabies, a highly fatal zoonotic disease, is a significant global public health threat. Currently, the pathogenic mechanism of rabies has not been fully elucidated, and no effective treatment for rabies is available. Increasing evidence shows that the tripartite-motif protein (TRIM) family of proteins participates in the host's regulation of viral replication. Studies have demonstrated the upregulated expression of tripartite-motif protein 21 (TRIM21) in the brain tissue of mice infected with the rabies virus. Related studies have shown that TRIM21 knockdown inhibits RABV replication, while overexpression of TRIM21 exerted the opposite effect. Knockdown of interferon-alpha and interferon-beta modulates the inhibition of RABV replication caused by TRIM21 knockdown and promotes the replication of the virus. Furthermore, our previous study revealed that TRIM21 regulates the secretion of type I interferon during RABV infection by targeting interferon regulatory factor 7 (IRF7). IRF7 knockdown reduced the inhibition of RABV replication caused by the knockdown of TRIM21 and promoted viral replication. TRIM21 regulates RABV replication via the IRF7-IFN axis. Our study identified TRIM21 as a novel host factor required by RABV for replication. Thus, TRIM21 is a potential target for rabies treatment or management.

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
BNIP3 (BCL2 and adenovirus E1B 19-kDa-interacting protein 3), which is a pro-apoptotic protein in the BCL-2 family involves a variety of cell signaling pathways, including mitochondrial dysfunction, mitochondrial autophagy, and apoptosis in vertebrates. However, the role of BNIP3 in the regulation of apoptosis and/or autophagy in crustaceans suffering virus infection is still limited. In this study, the mud crab (Scylla paramamosain) BNIP3 (SpBNIP3) was identified and studied to elucidate its association with the white spot syndrome virus (WSSV) infection. SpBNIP3 was widely expressed in all tested tissues and significantly down-regulated in the hemocytes of mud crab after WSSV infection. Knockdown of SpBNIP3 using RNA interference increased the apoptosis rate and Caspase 3 activity but decreased the mitochondrial membrane potential and autophagy levels, as well as viral copy number in mud crabs infected with WSSV. Additionally, the relationship between the viral infection and the autophagy of hemocytes was observed. The level of autophagy was reduced upon WSSV infection, and the activation of autophagy enriched the viral copy number. Taken together, the results of this study provide a new finding on the mechanism that SpBNIP3 may participate in the WSSV infection through the regulation of apoptosis and autophagy processes in mud crabs.

Tripartite motif (TRIM) proteins are a multifunctional family of ubiquitin E3 ligases involved in multiple biological processes. Studies have shown that many TRIM proteins in mammals play vital roles in the host defense against viral pathogens. In the present study, we identified a novel TRIM gene (MnTrim-like) from the oriental river prawn, Macrobrachium nipponense. Predicted MnTrim-like protein contains the characteristic RING finger domain. MnTrim-like was abundantly distributed in hepatopancreas, intestine, stomach, and gills. Upon white spot syndrome virus (WSSV) challenge, transcripts of MnTrim-like in the stomach were significantly up-regulated. Knockdown of MnTrim-like increased the expression of VP28 and decreased the synthesis of several antimicrobial peptides, including two crustins and one anti-lipopolysaccharide factor. Besides, silencing of these three antimicrobial peptides (AMPs) led to an increase in the expression of VP28 and WSSV copies. Moreover, it was found that injection of recombinant MnTrim-like protein with WSSV could decrease the transcription of VP28 and the number of virus particles. These results suggest that this MnTrim-like may restrict WSSV infection by positively regulating the expression of AMPs with antiviral activities and directly interacting with viral components. This study will broaden our understanding about the function of TRIM in crustacean during viral infection.

Abstract
Protein phosphorylation and dephosphorylation are the most common and important regulatory mechanisms in signal transduction, which play a vital role in immune defense response. Our previous study has found the level of tyrosine phosphorylation was significantly changed in the hemocytes of Fenneropenaeus chinensis upon white spot syndrome virus (WSSV) infection. In order to explore the relationship between protein phosphorylation and WSSV infection, the quantitative phosphoproteomics was employed to identify differential phosphorylated proteins in hemocytes of F. chinensis before and after WSSV infection, and elucidate the role of key differential phosphorylated proteins in WSSV infection process. The results showed that a total of 147 differential phosphorylated proteins were identified in the hemocytes, including 64 phosphorylated proteins and 83 dephosphorylated proteins, which were mostly enriched in pyruvate metabolism, TCA cycle, glycolysis, and ribosomal biosynthesis. Functional analysis of differential phosphorylated proteins showed that they were involved in cell apoptosis, cell phagocytosis, cell metabolism and antiviral infection. A total of 236 differential phosphorylation sites were found, including 91 modified sites in the phosphorylation proteins and 145 modified sites in the dephosphorylation proteins. Motif analysis showed that these phosphorylation sites could activate mitogen-activated protein kinase, P70 S6 kinase and other kinases in hemocytes. Moveover, the phosphorylation levels of eukaryotic protein initiation factor 4E binding proteins and histone H3 were further determined by ELISA and Western blotting, which both exhibited a significant increase post WSSV infection and reach their peak levels at 6 and 12 h, respectively. Moreover, we found that lactate, a metabolite closely related to pyruvate metabolism, TCA cycle and glycolysis, was significantly increased in the hemocytes after WSSV infection. This study revealed the protein phosphorylation response in hemocytes of F. chinensis to WSSV infection, which help to clarify the response characteristics and virus resistance mechanism of hemocytes in F. chinensis, and also facilitate further understanding of the interaction between WSSV and shrimp hemocytes.
