Abstract
The mammalian Sterile 20-like kinase 1/2 (MST1/2) belongs to the serine/threonine (GC) protein kinase superfamily. Collective studies confirm the vital role MST1/2 in inflammation and immunity. MST1/2 is closely related to the progress of inflammation. Generally, MST1/2 aggravates the inflammatory injury through MST1-JNK, MST1-mROS, MST1-Foxo3, and NF-κB pathways, as well as several regulatory factors such as tumor necrosis factor-α (TNF-α), mitochondrial extension factor 1 (MIEF1), and lipopolysaccharide (LPS). Moreover, MST1/2 is also involved in the regulation of immunity to balance immune activation and tolerance by regulating MST1/2-Rac, MST1-Akt1/c-myc, MST1-Foxos, MST1-STAT, Btk pathways, and lymphocyte function-related antigen 1 (LFA-1), which subsequently prevents immunodeficiency syndrome and autoimmune diseases. This article reviews the effects of MST1/2 on inflammation and immunity.

Abstract
Serine/threonine protein kinase 25 (STK25) is a critical regulator of ectopic lipid storage, glucose and insulin homeostasis, fibrosis, and meta-inflammation. More and more studies have revealed a strong correlation between STK25 and human diseases. On the one hand, STK25 can affect glucose and fatty acid metabolism in normal cells or tumors. On the other hand, STK25 participates in autophagy, cell polarity, cell apoptosis, and cell migration by activating various signaling pathways. This article reviews the composition and function of STK25, the energy metabolism and potential drugs that may target STK25, and the research progress of STK25 in the occurrence and development of tumors, to provide a reference for the clinical treatment of tumors.

Abstract
The mammalian sterile 20-like (MST) family belongs to the serine/threonine protein kinase (STK) superfamily and participates in a variety of biological processes, such as cell apoptosis, polarity, migration, immune regulation, inflammatory responses, and cancer. In the economically important bighead carp (Hypophthalmichthys nobilis), the STK gene family and immune-related biological functions may be helpful in increasing its economic yield. However, the comprehensive role of STKs in the bighead carp remains unclear. In this study, the five stk sequences from the bighead carp were divided into two classes: stk3/4 and stk24/25/26. Gene structure and motif prediction analyses confirmed that stk is conserved in the bighead carp. Compared to 26 other vertebrate species, teleosts (including bighead carp) possess more stk members because of teleost-specific whole-genome duplication. Synteny analysis revealed that stk3, stk24, stk25, and stk26 have been relatively conserved in bighead carp during evolution. Meanwhile, stk4 was lost in most Cyprinid species, including bighead carp, during evolution. RNA-seq data revealed that STK expression was associated with various pathogens, and the expression of these STKs (Hnstk3, Hnstk24a, Hnstk24b, Hnstk25, and Hnstk26) was different in seven tissues of bighead carp. In addition, we showed that STK expression levels were dramatically altered in the head kidney and that stk24 was involved in defense against Aeromonas hydrophila. This study provides a molecular basis for the analysis of stk function in bighead carp, and can be used as a reference for further phylogenomics.

Abstract
Krüppel-like factor 2a (KLF2A), a transcription factor of the krüppel-like family, is involved in regulating the immune molecules and is associated with viral infection. However, the function of KLF2A during viral infections in fish remains unclear. In this study, grass carp (Ctenopharyngodon idellus) was used to predict the target genes regulated by KLF2A. The results showed that the candidate target genes included four members of the serpin gene family (serpinb1l2, serpinc1, serpinh1a, and serpinh1b). Dual-luciferase experiments showed that klf2a positively regulates serpinc1 expression. Dose-dependent klf2a overexpression in C. idellus kidney (CIK) cells significantly upregulated the expression of serpinc1. Overexpressing klf2a or serpinc1 in CIK cells activated interferon responses and suppressed grass carp reovirus (GCRV) replication. Klf2a and serpinc1 co-expression inhibited GCRV replication. These results show that klf2a upregulates serpinc1 mRNA expression, promotes type 1 interferon responses, and suppresses GCRV infection. This study provides insights into the regulatory role and biological functions of KLF2A in host-virus interactions in fish.

Abstract
SERPINA1, a member of the serine protease inhibitor family, plays a role in viral infection and inflammation by regulating the activities of serine and cysteine proteases. To date, there have been no reports on the immune function of SERPINA1 in fishes. In this study, we first cloned the serpina1 gene of grass carp (Ctenopharyngodon idellus) and found that it could respond rapidly to the infection of Grass carp reovirus (GCRV), and overexpression of serpina1 could enhance the antiviral response of CIK cells. A polyclonal antibody of SERPINA1 was prepared, and the protein interacting with SERPINA1 was screened by CoIP/MS in grass carp hepatopancreas tissue. It was found that SERPINA1 interacted with coagulation factor 2 (CF2) and could degrade it in a dose-dependent manner. In addition, overexpression of cf2 contributed to the infection of GCRV in CIK cells, whereas co-expression of serpina1 and cf2 in grass carp reduced the copy number of GCRV in cells. The results showed that grass carp SERPINA1 could inhibit GCRV infection by degrading CF2. This study proposes that SERPINA1 can inhibit viral infection through interaction with the coagulation factor, providing new insights into the molecular mechanism of SERPINA1’s antiviral function.

Abstract
The regulation of host redox homeostasis is critically important in the immune response to pathogens. The "mammalian sterile 20-like" kinase 2 (MST2) has been shown to play a role in apoptosis, cell proliferation, and cancer; however, few studies have examined its ability to modulate redox homeostasis during innate immunity, especially in teleost fish. In this study, we cloned the MST2 gene of Ctenopharyngodon idella (CiMST2) and analyzed its tissue distribution. CiMST2 was present in most of the studied tissues, and it was most highly expressed in brain tissue. Expression patterns analysis revealed that MST2 mRNA and protein were significantly up-regulated under bacterial infection, suggesting that it is involved in the immune response. Bacterial stimulation significantly increased the level of antioxidases. To explore the interplay between CiMST2 and antioxidant regulation, we examined the effects of CiMST2 overexpression and conducted RNA interference assays in vitro. CiMST2 overexpression significantly increased the expression levels of nuclear factor E2-related factor 2 (Nrf2) and other antioxidases and vice versa, revealing that CiMST2 regulated host redox homeostasis via Nrf2-antioxidant responsive element (ARE) signaling. Overall, our findings provide a new perspective on the role of MST2 in innate immunity in teleosts as well as insights that will aid the prevention and control of disease in the grass carp farming industry.

Abstract
Scavenger receptor class B type 2 (SR-B2) is a pattern recognition receptor involved in innate immunity in mammals; however, the immunological function of SR-Bs in fish remains unclear. In this study, the full-length cDNA sequences of SR-B2a and SR-B2b from grass carp (Ctenopharyngodon idellus) were cloned and designated as CiSR-B2a and CiSR-B2b. Multiple alignments and phylogenetic analyses deduced that CiSR-B2a and CiSR-B2b had the highest evolutionary conservation and were closely related to the zebrafish (Danio rerio) homologs, DrSR-B2a and DrSR-B2b, respectively. Both CiSR-B2a and CiSR-B2b were expressed in all the tested tissues, with the highest expression levels found in the hepatopancreas. In Ctenopharyngodon idellus kidney cells (CIK), CiSR-B2a and CiSR-B2b were mainly located in the cytoplasm, and a small amount located on the plasma membrane. After challenge with Grass Carp Reovirus (GCRV), the expression of CiSR-B2a and CiSR-B2b were significantly upregulated in the spleen (about 10.27 and 27.19 times higher than that at 0 day, p < 0.01). With CiSR-B2a or CiSR-B2b overexpressed in CIK, the relative copy number of GCRV in the cells was both significantly increased compared to that in the control group, indicating that CiSR-B2a and CiSR-B2b may be important proteins during the infection processes of GCRV.

Abstract
Mammalian Ste20-like kinase 4 (MST4), a new member of the germinal-center kinase STE20 family, was recently demonstrated to be a negative regulator of inflammation. However, whether MST4 participates in the inflammatory response to fungal infection remains unknown. Our study investigated the role and molecular mechanisms of MST4 in mice cornea and corneal epithelial cells exposed to Aspergillus fumigatus (A. fumigatus). Protein level of MST4 was detected in mice corneas and human corneal epithelial cells (HCECs) by Western blot analysis. The MST4 protein level was significantly elevated in mice corneas infected with A. fumigatus and HCECs exposed to A. fumigatus. MST4 expression was also detected in mice corneas by immunofluorescence staining. Furthermore, we found recombinant MST4 inhibited proinflammatory cytokines expressions induced by A. fumigatus at both the mRNA and protein levels in mice corneas and HCECs. To further investigate the mechanism of MST4's anti-inflammatory effect in A. fumigatus keratitis, we verified recombinant MST4 can inhibit curdlan-mediated proinflammatory cytokines production in HCECs. Surprisingly, recombinant MST4 protein downregulated A. fumigatus-induced Dectin-1 expression in both mRNA and protein levels in mice corneas. Recombinant MST4 can inhibit the mRNA expression level of Dectin-1 which was induced by curdlan in HCECs. MST4 can also inhibit the expression of Dectin-1 in mRNA levels increased by Dectin-1 overexpression plasmid in HCECs. Moreover, A. fumigatus or curdlan significantly induced the phosphorylation of Syk, which was consequently suppressed by recombinant MST4. Finally, recombinant MST4 promotes HCECs proliferation, which contribute to cornea wound healing. Taken together, our results provide evidences that MST4 inhibits inflammatory signaling response in A. fumigatus keratitis by downregulating Dectin-1/p-Syk pathway and simultaneously promotes HCECs proliferation.

Autophagy Inhibits Grass Carp Reovirus (GCRV) Replication and Protects Ctenopharyngodon idella Kidney (CIK) Cells from Excessive Inflammatory Responses after GCRV Infection. Biomolecules 2020; 10:E1296. [PMID: 32911775 PMCID: PMC7564910 DOI: 10.3390/biom10091296] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Revised: 08/09/2020] [Accepted: 08/28/2020] [Indexed: 02/07/2023] Open
Abstract
Autophagy is an essential and highly conserved process in mammals, which is critical to maintaining physiological homeostasis, including cell growth, development, repair, and survival. However, the understanding of autophagy in fish virus replication is limited. In this study, we found that grass carp reovirus (GCRV) infection stimulated autophagy in the spleen of grass carp (Ctenopharyngodon idella). Moreover, both Western blot (WB) analysis and fluorescent tracer tests showed that GCRV infection induced the enhancement of autophagy activation in Ctenopharyngodon idella kidney (CIK) cells. Autophagy inducer rapamycin and autophagy inhibitor 3-MA pretreatment can inhibit and promote the proliferation of GCRV, respectively. In addition, grass carp autophagy-related gene 5 (CiATG5)-induced autophagy, as well as rapamycin, showed effects on GCRV replication in CIK cells. Transcriptome analysis revealed that the total number of differentially expressed genes (DEGs) in CiATG5 overexpression groups was less than that of the control during GCRV infection. Enrichment analysis showed that CiATG5 overexpression induced the enhancement of autophagy, lysosome, phagosome, and apoptosis in the early stage of GCRV infection, which led to the clearance of viruses. In the late stage, steroid biosynthesis, DNA replication, terpenoid backbone biosynthesis, and carbon metabolism were upregulated, which contributed to cell survival. Moreover, signaling pathways involved in the immune response and cell death were downregulated in CiATG5 overexpression groups. Further study showed that CiATG5 repressed the expression of inflammatory response genes, including cytokines and type I interferons. Taken together, the results demonstrate that autophagy represses virus replication and attenuates acute inflammatory responses to protect cells.

FISH & SHELLFISH IMMUNOLOGY 2019; 92:600-611. [PMID: 31252046 DOI: 10.1016/j.fsi.2019.06.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 06/04/2019] [Accepted: 06/09/2019] [Indexed: 06/09/2023]
Abstract
Autophagy is an essential and conserved process that plays an important role in physiological homeostasis, adaptive response to stress and the immune response. Autophagy-related proteins (ATGs) are key components of the autophagic machinery. In the study, grass carp (Ctenopharyngodon idella) autophagy-related gene 5 (ATG5) and 12 (ATG12) were identified. In the gill and intestine, ATG5 and ATG12 were highly expressed, but after grass carp reovirus (GCRV) infection, they were decreased significantly. In Ctenopharyngodon idella kidney (CIK) cells, the sharp variation of ATG5 and ATG12 expression was observed after poly(I:C) infection. Subcellular localisation showed that ATG5 and ATG12 were evenly distributed in the cytoplasm and nucleus. However, the interaction between ATG5 and ATG12 was only found in cytoplasm in both 293T cells and CIK cells. In addition, the overexpression of ATG5 or ATG12 in 293T cells showed enhanced autophagy, and autophagic process was facilitated when ATG5 and ATG12 were simultaneously overexpressed. Dual-luciferase activity assay indicated that both ATG5 and ATG12 remarkably suppressed the promoter activity of IRF3, IRF7, and IFN-I. Further, ATG5 and ATG12 conjugate showed far stronger inhibitory affection on the expression of IFN-I than either ATG5 or ATG12 in response to poly(I:C) or GCRV infection. Taken together, the results demonstrate that grass carp ATG5 and ATG12 play an important role in innate immunity and autophagy.

Abstract
Tripartite motif (TRIM) proteins are key components of the innate immune system, functioning as antiviral restriction factors or modulating signaling cascades that lead to proinflammatory cytokine induction. In the present study, the TRIM family gene TRIM23 from grass carp (Ctenopharyngodon idella) was cloned and characterised. TRIM23 was moderately expressed in the examined tissues, and the significantly altered expression was observed after grass carp reovirus (GCRV) and poly(I:C) infection. Dual-luciferase activity assay showed that TRIM23, especially its C-terminal domain ARF, depressed the promoter activity of IRF3 and IRF7. The subcellular localisation showed that TRIM23 protein was located in the cytoplasm and could be recruited by both TRAF6 and MyD88. Furthermore, TRIM23 was confirmed to interact with either TRAF6 or MyD88 by the bimolecular fluorescence complementation (BiFC) system in CIK cells. Additionally, autophagy was enhanced by over-expressed TRIM23 in 293T cells. Taken together, our results demonstrate that TRIM23 gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the TRIM23 in teleosts.

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.

Abstract
The nucleotide-binding domain and leucine-rich-repeat-containing (NLR) proteins regulate innate immunity. Although the positive regulatory impact of NLRs is clear, their inhibitory roles are not well defined. In the present study, the NLR family gene NLRX1 from grass carp (Ctenopharyngodon idella) was cloned and characterised. NLRX1 was widely expressed in all tissues examined, albeit at varying levels. After exposure to the grass carp reovirus (GCRV), NLRX1 mRNA expression levels were altered in immune organs, and dramatically altered in liver. Subcellular localisation indicated that NLRX1 protein co-localised with the mitochondria in the transfected cells. Additionally, the bimolecular fluorescence complementation (BiFC) system was introduced to detect the interaction between tumour necrosis factor (TNF) receptor associated factor 6 (TRAF6) and NLRX1. Moreover, deficient of NLRX1 in CIK cells with small interference RNA (siRNA) promoted polyinosinic:polycytidylic acid (poly (I:C))-induced IFN-related genes production, including IRF3, IRF7, and IFN-I, which reveals that NLRX1 is a negative regulator of IFN. Taken together, our results demonstrate that NLRX1 gene plays an important role in innate immune regulation and provide new insights into understanding the functional characteristics of the NLRX1 in teleosts.
