Chaumont L, Collet B, Boudinot P. Protein kinase double-stranded RNA-dependent (PKR) in antiviral defence in fish and mammals. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2023; 145:104732. [PMID: 37172664 DOI: 10.1016/j.dci.2023.104732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 05/07/2023] [Accepted: 05/09/2023] [Indexed: 05/15/2023]
Abstract
The interferon-inducible double-stranded RNA-dependent protein kinase (PKR) is one of the key antiviral arms of the innate immune system. Upon binding of viral double stranded RNA, a viral Pattern Associated Molecular Pattern (PAMP), PKR gets activated and phosphorylates the eukaryotic initiation factor 2α (eIF2α) resulting in a protein shut-down that limits viral replication. Since its discovery in the mid-seventies, PKR has been shown to be involved in multiple important cellular processes including apoptosis, proinflammatory and innate immune responses. Viral subversion mechanisms of PKR underline its importance in the antiviral response of the host. PKR activation pathways and its mechanisms of action were previously identified and characterised mostly in mammalian models. However, fish Pkr and fish-specific paralogue Z-DNA-dependent protein kinase (Pkz) also play key role in antiviral defence. This review gives an update on the current knowledge on fish Pkr/Pkz, their conditions of activation and their implication in the immune responses to viruses, in comparison to their mammalian counterparts.

Abstract
Upon infection, the herpes viruses create a cellular environment suitable for survival, but innate immunity plays a vital role in cellular resistance to viral infection. The UL13 protein of herpesviruses is conserved among all herpesviruses and is a serine/threonine protein kinase, which plays a vital role in escaping innate immunity and promoting viral replication. On the one hand, it can target various immune signaling pathways in vivo, such as the cGAS-STING pathway and the NF-κB pathway. On the other hand, it phosphorylates regulatory many cellular and viral proteins for promoting the lytic cycle. This paper reviews the research progress of the conserved herpesvirus protein kinase UL13 in immune escape and viral replication to provide a basis for elucidating the pathogenic mechanism of herpesviruses, as well as providing insights into the potential means of immune escape and viral replication of other herpesviruses that have not yet resolved the function of it.

FISH PHYSIOLOGY AND BIOCHEMISTRY 2022; 48:631-644. [PMID: 35411444 DOI: 10.1007/s10695-022-01072-6] [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: 11/03/2021] [Accepted: 03/30/2022] [Indexed: 06/14/2023]
Abstract
As an intermediate link between multiple cellular stresses and cellular responses, p53, together with its upstream and downstream regulators and related genes, constitutes a complex network that regulates cellular stresses and cellular responses. However, no studies have investigated p53 in Phoxinus lagowskii, particularly the expression of p53 under different hypoxic conditions. In the present study, the cDNA of p53 from the Phoxinus lagowskii was cloned by the combination of homology cloning and rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of Pl-p53 was 1878 bp, including an open reading frame (ORF) of 1116 bp encoding a polypeptide of 371 amino acids with a predicted molecular weight of 41.22 kDa and a theoretical isoelectric point of 7.38. Quantitative real-time (qRT) PCR assays revealed that Pl-p53 was commonly expressed in all tissues examined, with highest expression in the heart. In addition, we investigated the expression of Pl-p53 in different tissues under different hypoxic conditions. In the short-term hypoxia group, Pl-p53 expression was down-regulated in both the brain and heart. The Pl-p53 expression was significantly elevated at 6 h in the muscle and liver, and was significantly up-regulated at 24 h in spleen. These results suggest that Pl-p53 plays different regulatory roles and provide a theoretical basis for the changes of p53 in fish facing hypoxic environments.

Abstract
In the present study, the modulation of the transcriptional immune response (microarray analysis) in the head kidney (HK) of the anadromous fish Atlantic salmon (Salmo salar) fed a diet supplemented with an olive fruit extract (AQUOLIVE®) was evaluated. At the end of the trial (133 days), in order to investigate the immunomodulatory properties of the phytogenic tested against a bacterial infection, an in vivo challenge with Aeromonas salmonicida was performed. A total number of 1,027 differentially expressed genes (DEGs) (805 up- and 222 downregulated) were found when comparing the transcriptomic profiling of the HK from fish fed the control and AQUOLIVE® diets. The HK transcripteractome revealed an expression profile that mainly favored biological processes related to immunity. Particularly, the signaling of i-kappa B kinase/NF-kappa and the activation of leukocytes, such as granulocytes and neutrophils degranulation, were suggested to be the primary actors of the innate immune response promoted by the tested functional feed additive in the HK. Moreover, the bacterial challenge with A. salmonicida that lasted 12 days showed that the cumulative survival was higher in fish fed the AQUOLIVE® diet (96.9 ± 6.4%) than the control group (60.7 ± 13.5%). These results indicate that the dietary supplementation of AQUOLIVE® at the level of 0.15% enhanced the systemic immune response and reduced the A. salmonicida cumulative mortality in Atlantic salmon smolts.

Abstract
As a NAD+-dependent deacetylase, SIRT1 is widely involved in apoptosis and cellular inflammation via multiple pathways such as p53, NF-кB and STAT. More and more studies have shown that p53 is the first non-histone deacetylation target of SIRT1. SIRT1-p53 axis thus plays an important role in mammalian cells. IRF9 is an important member of interferon regulator factor family and performs an important role in innate immunity against foreign virus invasion. More importantly, human IRF9 can suppress the SIRT1-p53 axis. However, the functions and relationship between IRF9 and SIRT1-p53 axis are rarely studied in fish. To this end, we made a preliminary research on the functions of grass carp (Ctenopharyngodon idella) IRF9, SIRT1 and p53 in apoptosis and innate immunity. Firstly, we cloned and identified the ORF of SIRT1 (named CiSIRT1, MN125614) from C. idella and demonstrated that CiIRF9 promoted apoptosis, while CiSIRT1 inhibited apoptosis by flow cytometry and TUNEL experiments. Next, we found the interaction between CiSIRT1 and Cip53 in vivo by co-immunoprecipitation experiments. Moreover, the colocalization analysis also showed CiSIRT1 and Cip53 were mainly distributed in nucleus. Thirdly, we got a conclusion that CiIRF9 can repress the expression of CiSIRT1, implying that CiIRF9 regulates CiSIRT1-p53 axis. Finally, CiSIRT1 mRNA level was significantly up-regulated and the expression reached the highest level at 24 h post poly (I:C) stimulation in CIK cells. So, CiSIRT1 may exert an important function in innate immunity. Furthermore, we found CiSIRT1 down-regulated the expression of CiIFN1. In summary, CiIRF9 promotes apoptosis and innate immunity by inhibiting SIRT1-p53 axis. These findings will provide a new theoretical basis for the research on teleost innate immunity.

Abstract
SAMHD1 is an innate immunity restriction factor that inhibits virus infection through IRF3-mediated antiviral and apoptotic responses. Fish SAMHD1 shares some similar properties with those in mammals. In this study, a SAMHD1 orthologue from grass carp (Ctenopharyngodon idellus) was cloned and characterized. The full-length cDNA of CiSAMHD1 is 2792 bp with an ORF of 1884 bp encoding a polypeptide of 627 amino acids. Multiple alignments showed that SAMHD1 is highly conserved among different species. Phylogenetic tree analysis revealed that CiSAMHD1 shared a high degree of homology with Sinocyclocheilus rhinocerous SAMHD1. Expression analysis indicated that CiSAMHD1 was widely expressed in all tissues tested including the brain, eyes, spleen, gill, intestine, liver, heart and kidney. It was significantly up-regulated in spleen, liver and intestines after treatment with poly I:C. Also, CiSAMHD1 can be induced following stimulation with recombinant IFN in CIK cells. The promoter sequence of CiSAMHD1 was identified to explore the mechanism underlying the transcriptional regulation of CiSAMHD1. The promoter sequence of CiSAMHD1 (1370 bp) consists of IRF1, IRF3, IRF9 and p65 binding elements. Gel mobility shift assay also showed that IRF1, IRF3, IRF9 and p65 prokaryotic proteins can separately interact with CiSAMHD1 promoter. Dual luciferase assay and q-PCR suggested that the promoter of CiSAMHD1 can be activated by the overexpression of CiIRF3 and CiIRF9, but cannot be triggered by CiIRF1 and Cip65. In contrast, knockdown of CiIRF3 or CiIRF9 inhibits the transcription of CiSAMHD1. Intriguingly, CCK assay suggested that CiSAMHD1 decreased cell viability. TUNEL apoptosis assay and Hoechst 33258 staining assay indicated that apoptosis is induced by the overexpression of CiSAMHD1. Crystal violet staining, detection of two GCRV genes (vp3 and vp5) and viral titration showed that CiSAMHD1 can suppress the proliferation of grass carp reovirus (GCRV) in CIK cells.

Abstract
Interleukin-1 receptor-associated kinase (IRAK) family members play important roles in myeloid differentiation primary response 88 (MyD88)-dependent toll-like receptor (TLR) signaling, the crucial innate immune pathway in vertebrates. In the present study, the IRAK family gene IRAK-M (also called IRAK3) from grass carp (Ctenopharyngodon idella) was cloned and characterised. IRAK-M was mainly enriched in the spleen, and the significantly altered expression was observed after grass carp reovirus (GCRV) infection. Subcellular localisation showed that IRAK-M protein distributed uniformly in the entire cell and co-localised with MyD88 in the cytoplasm of transfected cells. Additionally, the interaction between IRAK-M and MyD88 was confirmed by bimolecular fluorescence complementation (BiFC) system. Moreover, deficient of IRAK-M in C. idella kidney cell line (CIK) with small interference RNA (siRNA) upregulated polyinosinic:polycytidylic acid (poly(I:C))-induced inflammatory cytokines production, including interleukin 8 (IL-8), IL-6, and tumour necrosis factor α (TNF-α), which reveals that IRAK-M functions as a negative regulator of inflammatory cytokines. Taken together, our results demonstrate that IRAK-M gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the IRAK-M in teleosts.
